References in this prospectus to "the company," "we," "us," "our," or like terms refer to Hornbeck Offshore Services, Inc. and its subsidiaries, except as otherwise indicated. We refer to offshore supply vessels as "OSVs" in this prospectus. References in this prospectus to "deepwater" include deepwater areas, generally 1,000feet to 5,000feet in depth, and ultra-deepwater areas, generally more than 5,000feet in depth. HORNBECK OFFSHORE SERVICES, INC. We are a leading owner and operator of deepwater-capable offshore supply vessels serving the offshore oil and gas industry. In 1997, we commenced a growth-oriented newbuild program using our proprietary deepwater OSV designs. We currently operate a fleet of 11 deepwater OSVs in the Gulf of Mexico with an average age of approximately two years. We have 10 additional deepwater OSVs currently planned or under construction. Upon completion of this offering, we will be the only publicly traded company with a significant concentration of deepwater OSVs in the Gulf of Mexico. Demand for our OSV services is primarily driven by offshore drilling and production activity. In the late-1990s, we identified a significant opportunity in and developed a plan to exploit the emerging interest in deepwater exploration and production in the Gulf of Mexico. Since then, the deepwater Gulf of Mexico has become an increasingly active oil and natural gas producing region. According to the Minerals Management Service, in 2001, the deepwater accounted for approximately 59% of total Gulf of Mexico oil production and 23% of total Gulf of Mexico natural gas production. Successful exploration and development in deepwater areas requires a new generation of expensive drilling rigs and production platforms and other advanced drilling and production technology. We believe that these projects are served most effectively by a new generation of deepwater OSVs capable of supporting day-to-day operations in a manner that minimizes costly downtime in terms of both drilling rig dayrates and lost oil and natural gas production. We believe that the existing fleet of conventional, 180' OSVs working in shallow water areas, such as the continental shelf of the Gulf of Mexico, is not capable of operating effectively in the deepwater market due to insufficient cargo capacity and lack of dynamic positioning capability. Since 1997, we have assembled a core team of naval architects and other marine professionals to design and operate new classes of OSVs that specifically address the challenges of deepwater operations. All of our deepwater OSVs have been built based on the proprietary designs and to the specifications of our in-house design team. As a result, all of our deepwater OSVs have enhanced capabilities that allow them to be used effectively in all stages of a deepwater project and for specialty services. Although we currently operate exclusively in the Gulf of Mexico, our OSVs are capable of operating in all deepwater regions around the world. We are also a leading provider of marine transportation services to the energy industry in the northeastern United States and Puerto Rico. We own and operate a fleet of 13 ocean-going tugs, 16 ocean-going tank barges and one coastwise tanker. We believe our tug and tank barge business complements our OSV business, provides additional revenue and geographic diversification and allows us to offer another line of services to integrated oil and gas companies. 1

Demand for our tug and tank barge services is driven by the consumption of refined petroleum products. OUR COMPETITIVE STRENGTHS Technologically Advanced Fleet of Deepwater OSVs. Our in-house team of naval architects designed our OSVs to be equipped with sophisticated technologies and increased capacities, allowing them to operate more safely and efficiently in deepwater regions than conventional, 180' OSVs. These enhanced capabilities include dynamic positioning, roll reduction and controllable pitch thrusters, as well as two to three times the dry bulk capacity and deck space, three to ten times the liquid mud capacity and two to four times the deck tonnage compared to conventional OSVs. Our advanced cargo handling systems allow for dry bulk and liquid cargoes to be loaded and unloaded three times faster than with conventional systems, while the solid state controls of our engines typically result in 20% greater fuel efficiency than vessels powered by conventional engines. We believe that we earn higher average dayrates and utilization rates than those of our peers for the following reasons: the superior capabilities of our deepwater OSVs and the collaborative efforts of our in-house design team in providing marine engineering solutions to our customers. Young OSV Fleet. We believe that we operate the youngest fleet of OSVs in the Gulf of Mexico. While over 70% of the Gulf of Mexico OSV fleet is over 18 years old, the average age of our OSV fleet is approximately two years, and we have 10 additional deepwater OSVs currently planned or under construction. Newer vessels experience less downtime and require significantly less capital expenditures for scheduled drydockings and maintenance compared to older vessels. We believe that our operation of new technologically advanced, deepwater OSVs gives us a competitive advantage in obtaining long-term contracts for our vessels and in attracting and retaining crews. Since we accepted delivery of our first OSV in November 1998, the average utilization rate for our OSVs has been approximately 95%. According to One Offshore the Gulf of Mexico industry average was approximately 75% over the same time period, based on vessels available for service. We expect that our newer, larger, faster and more cost-efficient vessels will remain in high demand as deepwater exploration, development and production activity continues to increase globally. Leading Presence in Core Target Markets. We are the second largest operator of deepwater OSVs in the Gulf of Mexico. We have a larger presence in the deepwater Gulf of Mexico than any of our publicly traded competitors, with 11 OSVs. We will strengthen this position and our ability to serve other markets following delivery of the 10 deepwater OSVs we currently have planned or under construction. We operate the largest fleet of tugs and tank barges for the transportation of petroleum products in Puerto Rico and believe that we are also the fourth largest tank barge transporter of petroleum products in New York Harbor. Successful Track Record of Deepwater OSV Construction. Our management possesses significant naval architecture, marine engineering and shipyard experience. We believe we are unique in the manner in which we design our own OSVs and work closely with our contracted shipyards in their construction. In addition, we typically source and supply much of the owner-furnished equipment from vendors other than the shipyard, comprising a significant portion of the aggregate cost of a vessel. We delivered our current fleet of 11 deepwater OSVs substantially on time and on budget. We believe that our history of delivering new vessels without significant delays provides us with a competitive advantage in obtaining contracts for our vessels prior to their actual delivery. Favorable OPA 90 Fleet Status. Based upon our analysis of the industry, we believe that at the time the Oil Pollution Act of 1990, or OPA 90, was passed, approximately 50% of the single hulled tank barge capacity serving the northeastern United States was required to be retired or substantially reconstructed before 2005. Eleven of our 16 tank barges are not required under 2

OPA 90 to be retired or double hulled until 2015. Of the remainder, three are required to be retired or modified before 2005, and two in 2009. Our coastwise tanker is not subject to OPA 90 retirement dates. Because most of our tank barges are not required to be double hulled until 2015, we believe we have a competitive advantage over operators with significant numbers of tank barges that must be retired or modified to add double hulls before that date. Experienced Management Team with Proven Track Record. Our senior management team has an average of 18 years of domestic and international marine transportation industry-related experience. We believe that our team has successfully demonstrated its ability to grow our fleet through new construction and strategic acquisitions and to secure profitable contracts for our vessels in favorable and unfavorable market conditions. Moreover, our in-house engineering team enables us to design and manage our new vessel construction program, adapt our vessels for specialized purposes, oversee and manage the drydocking process and provide custom marine engineering solutions to our customers. We believe this will continue to result in a lower overall cost of ownership over the life of our vessels compared to our competitors, as well as a competitive advantage in securing contracts for our OSVs as the benefits of our proprietary designs and in-house engineering capabilities are recognized by our customers. Numerous Industry-Recognized Quality and Safety Certifications. On a voluntary basis we have obtained certifications and classifications that are not generally held by other companies in our industry. For example, we are the only OSV company operating in the Gulf of Mexico that is approved under the U.S. Coast Guard's Streamlined Inspection Program and is fully International Safety Management code certified with the American Bureau of Shipping. We believe that our numerous industry certifications provide us with a competitive advantage because oil and gas operators increasingly value safety due to the environmental and regulatory sensitivity associated with offshore drilling and production activity. OUR STRATEGY We recently adopted the following mission statement, which we believe summarizes our strategy: "Our mission is to be recognized as the energy industry's marine transportation and service company of choice for our customers, employees and investors through innovative, high quality, value-added business solutions delivered with enthusiasm, integrity and professionalism with the utmost regard for the safety of individuals and the protection of the environment." To implement our mission, we have developed a strategy including the following elements: Maintain Technologically Advanced Fleet. We are committed to applying existing or developing new technologies in each new vessel construction program in order to continue to improve our service offerings and to meet the evolving needs of our customers. Maintain Strong Focus in Deepwater Regions. We intend to maintain our focus on operating high quality OSVs in deepwater regions. We believe that deepwater oil and gas producing regions worldwide will continue to be active areas for exploration and development in the foreseeable future. Expand Fleet Through Newbuilds and Selective Acquisitions. We plan to expand our fleet through construction of new vessels, including our recently announced eight-vessel newbuild program, and strategic acquisitions. Market demand for vessels, including demand in international markets, will be the main determinant of the level and timing of construction of additional vessels. We believe that acquisition opportunities are likely to arise as consolidation in our industry continues. Pursue Optimal Mix of Long-Term and Short-Term Contracts. We seek to balance our portfolio of contracts with both long-term and short-term charters. Long-term contracts provide more predictable cash flow, and short-term charters may provide the opportunity to benefit from increasing dayrates. 3

Continue to Leverage Existing Customer Relationships. We intend to build upon existing customer relationships by expanding the services we offer to those customers with diversified marine transportation needs. Many integrated oil and gas companies require OSVs to support their exploration and production activities and ocean-going tugs and tank barges to support their refining, trading and retail distribution activities. In addition, many of our customers conduct operations in international markets and have expressed interest in chartering our OSVs for use overseas. Our management team has significant international experience and is currently evaluating several such opportunities. Optimize Tug and Tank Barge Operations. Prior to our acquisition of tugs and tank barges from the Spentonbush/Red Star Group, those vessels were largely dedicated to the use of Amerada Hess and its affiliates in New York Harbor. Since that acquisition, we have consolidated the operational management of our entire tug and tank barge fleet, including our Puerto Rican fleet, in our Brooklyn facility. This will better enable us to market our services to customers other than Amerada Hess in the northeastern United States, while we continue our efforts to reduce costs and otherwise optimize utilization. RECENT DEVELOPMENTS Delivery of the HOS Brimstone. On June 13, 2002, we took delivery of the HOS Brimstone, our second 265 Class OSV. The HOS Brimstone was immediately deployed under a one-year time charter with a large international independent oil and gas company to support its deepwater exploration and production activities. Two of our other OSVs have been supporting this customer's deepwater exploratory drilling operations in the Gulf of Mexico since April 2000. We also expect to take delivery of two more 265 Class OSVs, the HOS Sandstorm and the HOS Stormridge, in the third quarter of 2002. Commencement of Eight-Vessel Newbuild Program. In April 2002, our Board of Directors approved a newbuild program for the construction of eight additional deepwater OSVs. On May 1, 2002, we signed a definitive agreement with a shipyard for the construction of the first four vessels of this program, each of which will be a 240ED, our newest class of deepwater OSV. We presently anticipate delivery of all four vessels between June and December 2003. Aggregate construction costs for the four vessels, before allocation of construction period interest, are expected to be approximately $53.0 million. We plan to fund these costs with a portion of the proceeds from this offering. We are currently seeking construction bids from shipyards for the last four vessels of this program. ---------------------- Our principal executive offices are located at 414 North Causeway Boulevard, Mandeville, Louisiana 70448, and our telephone number is (985) 727-2000. 4

EBITDA should not be considered in isolation or as a substitute for net income, cash flow or other income or cash flow data or as a measure of a company's profitability or liquidity and is not a measure calculated in accordance with generally accepted accounting principles. EBITDA is not necessarily comparable with similarly titled measures reported by other companies. (5) Calculated as EBITDA, as defined in footnote (4) above, divided by cash interest paid. (6) Utilization rates are average rates based on a 365-day year. Vessels are considered utilized when they are generating revenues. (7) Average dayrates represent average revenue per day, which includes charter hire and brokerage revenue, based on the number of days during the period that the OSVs generated revenue. (8) Average dayrates represent average revenue per day, including time charters, brokerage revenue, revenues generated on a per-barrel-transported basis, demurrage, shipdocking and fuel surcharge revenue, based on the number of days during the period that the tank barges generated revenue. For purposes of brokerage arrangements, this calculation excludes that portion of revenue that constitutes a "pass-through" to the customer of the cost of in-chartering third party equipment. 7

RISK FACTORS In considering whether to invest in our common stock, you should carefully read and consider the risks described below, together with all of the information we have included in this prospectus. RISKS RELATING TO OUR BUSINESS DEMAND FOR OUR SERVICES SUBSTANTIALLY DEPENDS ON THE LEVEL OF ACTIVITY IN OFFSHORE OIL AND GAS EXPLORATION, DEVELOPMENT AND PRODUCTION. The level of offshore oil and gas exploration, development and production activity has historically been volatile and is likely to continue to be so in the future. The level of activity is subject to large fluctuations in response to relatively minor changes in a variety of factors that are beyond our control, including: - prevailing oil and natural gas prices and expectations about future prices and price volatility; - the cost of offshore exploration for, production and transportation of oil and gas; - worldwide demand for oil and natural gas; - consolidation of oil and gas and oil service companies operating in the deepwater Gulf of Mexico; - availability and rate of discovery of new oil and gas reserves in offshore areas; - local and international political and economic conditions and policies; - technological advances affecting energy production and consumption; - weather conditions; - environmental regulation; and - the ability of oil and gas companies to generate or otherwise obtain funds for capital. We expect levels of oil and gas exploration, development and production activity to continue to be volatile and affect the demand for our offshore supply vessels, or OSVs. A prolonged, material downturn in oil and natural gas prices is likely to cause a substantial decline in expenditures for exploration, development and production activity, which could result in a corresponding decline in the demand for OSVs. Moreover, increases in oil and natural gas prices and higher levels of expenditure by oil and gas companies for exploration, development and production may not result in increased demand for our OSVs. INCREASES IN THE SUPPLY OF OSVS COULD DECREASE DAYRATES. We and certain of our competitors have announced construction of approximately 33 new U.S.-flagged OSVs, including the 10 OSVs we currently have planned or under construction. A remobilization to the Gulf of Mexico of U.S.-flagged OSVs operating in other regions or a repeal or significant modification of the Jones Act, which would permit OSVs that are either foreign- flagged, -built, -owned or -operated to engage in the U.S. coastwise trade, would also result in an increase in capacity. Any increase in the supply of OSVs, whether through new construction, refurbishment or conversion of vessels from other uses, or remobilization, could not only lower charter rates, which would adversely affect our revenues and profitability, but could also worsen the impact of any downturn in oil and natural gas prices on our results of operations and financial condition. We currently conduct our OSV operations exclusively in the Gulf of Mexico and therefore are dependent on levels of activity in that region, which may from time to time differ from levels of 8

activity in other regions of the world. The recent decline in oil and natural gas prices has resulted in reduced offshore drilling activity in the shallow water areas of the Gulf of Mexico and, consequently, a decrease in the demand for OSV services and lower dayrates in those areas. INTENSE COMPETITION IN THE OSV INDUSTRY COULD REDUCE OUR PROFITABILITY AND MARKET SHARE. Contracts for our deepwater OSVs are generally awarded on an intensely competitive basis. The most important factors determining whether a contract will be awarded include: - capability of the vessels; - ability to meet the customer's schedule; - safety record; - reputation; - price; and - experience. Many of our major competitors are diversified multinational companies. These companies have substantially greater financial resources and larger operating staffs than we do. They may be better able to compete in making vessels available more quickly and efficiently, meeting the customer's schedule and withstanding the effect of declines in dayrates. They may also be better able to weather a downturn in the oil and gas industry. As a result, we could lose customers and market share to these competitors. THE FAILURE TO SUCCESSFULLY COMPLETE CONSTRUCTION OF OUR VESSELS ON SCHEDULE AND ON BUDGET AND TO UTILIZE THOSE AND THE OTHER VESSELS IN OUR FLEET AT PROFITABLE LEVELS COULD ADVERSELY AFFECT OUR FINANCIAL CONDITION AND RESULTS OF OPERATIONS. We have six deepwater OSVs under construction and presently have plans to construct four more deepwater OSVs. Our construction projects are subject to the risks of delay and cost overruns inherent in any large construction project, including shortages of equipment, unforeseen engineering problems, work stoppages, weather interference, unanticipated cost increases, inability to obtain necessary certifications and approvals and shortages of materials or skilled labor. Significant delays could have a material adverse effect on anticipated contract commitments with respect to vessels under construction, and significant cost overruns or delays could adversely affect our financial condition and results of operations. Moreover, customer demand for vessels currently under construction may not be as strong as we presently anticipate, and our inability to obtain contracts on anticipated terms or at all may have a material adverse effect on our expected financial results. In addition, our OSVs are typically chartered or hired to provide services to a specified drilling rig. A delay in the availability of a drilling rig to our customer may have an adverse impact on our utilization of the contracted vessel and thus on our financial condition and results of operations. IF WE ARE UNABLE TO ACQUIRE ADDITIONAL VESSELS OR BUSINESSES AND SUCCESSFULLY INTEGRATE THEM INTO OUR OPERATIONS, OUR ABILITY TO GROW MAY BE ADVERSELY AFFECTED. We regularly consider possible acquisitions of single vessels, vessel fleets and businesses that complement our existing operations. We can give no assurance that we will be able to identify desirable acquisition candidates or that we will be successful in entering into definitive agreements on satisfactory terms. Even if we consummate an acquisition, we may be unable to integrate it into our existing operations successfully or realize the anticipated benefits of the acquisition. The process of integrating acquired operations into our own may result in unforeseen operating difficulties and may require significant management attention and financial resources. 9

Future acquisitions could result in the incurrence of additional indebtedness and liabilities, which could have a material adverse effect on our financial condition and results of operations. REVENUES FROM OUR TUG AND TANK BARGE SERVICES COULD BE ADVERSELY AFFECTED BY A DECLINE IN DEMAND FOR DOMESTIC REFINED PETROLEUM PRODUCTS AND CRUDE OIL OR A CHANGE IN EXISTING METHODS OF DELIVERY IN RESPONSE TO INSUFFICIENT AVAILABILITY OF TUG AND TANK BARGE SERVICES AND OTHER CONDITIONS. A reduction in domestic consumption of refined petroleum products or crude oil may adversely affect the revenues of our tug and tank barge services and therefore our financial condition and results of operation. Weather conditions also affect demand for our tug and tank barge services. For example, a mild winter may reduce demand for heating oil in the northeastern United States. Moreover, alternative methods of delivery of refined petroleum products or crude oil may develop as a result of insufficient availability of tug and tank barge services, the cost of compliance with environmental regulations or increased liabilities connected with the transportation of refined petroleum products and crude oil. CONSTRUCTION OF ADDITIONAL REFINED PETROLEUM PRODUCT PIPELINES WOULD HAVE A MATERIAL ADVERSE EFFECT ON OUR TUG AND TANK BARGE REVENUES. Long-haul transportation of refined petroleum products and crude oil is generally less costly by pipeline than by tank barge. While there are significant impediments to building new pipelines such as high capital costs and environmental concerns, entities may propose new pipeline construction to meet demand for petroleum products. To the extent new pipeline segments are built or existing pipelines converted to carry such products, such activity could have an adverse effect on our ability to compete in particular markets. WE ARE SUBJECT TO COMPLEX LAWS AND REGULATIONS, INCLUDING ENVIRONMENTAL REGULATIONS, THAT CAN ADVERSELY AFFECT THE COST, MANNER OR FEASIBILITY OF DOING BUSINESS. Increasingly stringent federal, state and local laws and regulations governing worker health and safety and the manning, construction and operation of vessels significantly affect our operations. Many aspects of the marine industry are subject to extensive governmental regulation by the United States Coast Guard, the National Transportation Safety Board and the United States Customs Service and to regulation by private industry organizations such as the American Bureau of Shipping. The Coast Guard and the National Transportation Safety Board set safety standards and are authorized to investigate vessel accidents and recommend improved safety standards, while the Customs Service is authorized to inspect vessels at will. Our operations are also subject to federal, state, local and international laws and regulations that control the discharge of pollutants into the environment or otherwise relate to environmental protection. Compliance with such laws and regulations may require installation of costly equipment or operational changes. Failure to comply with applicable laws and regulations may result in administrative and civil penalties, criminal sanctions, imposition of remedial obligations or the suspension or termination of our operations. Some environmental laws impose strict liability for remediation of spills and releases of oil and hazardous substances, which could subject us to liability without regard to whether we were negligent or at fault. These laws and regulations may expose us to liability for the conduct of or conditions caused by others, including charterers. Moreover, these laws and regulations could change over time in ways that substantially increase our costs. Any changes in laws, regulations or standards that would impose additional requirements or restrictions may harm our business, financial condition and results of operations. We are also subject to the Merchant Marine Act of 1936, which provides that, upon proclamation by the President of a national emergency or a threat to the security of the national defense, the Secretary of Transportation may requisition or purchase any vessel or other watercraft owned by United States citizens (which includes United States corporations), 10

including vessels under construction in the United States. If one of our OSVs, tugs or tank barges were purchased or requisitioned by the federal government under this law, we would be entitled to be paid the fair market value of the vessel in the case of a purchase or, in the case of a requisition, the fair market value of charter hire. However, if one of our tugs is requisitioned or purchased and its associated tank barge is left idle, we would not be entitled to receive any compensation for the lost revenues resulting from the idled barge. We would also not be entitled to be compensated for any consequential damages we suffer as a result of the requisition or purchase of any of our OSVs, tugs or tank barges. The purchase or the requisition for an extended period of time of one or more of our OSVs, tugs or tank barges may harm our business, results of operations and financial condition. Finally, we are subject to the Merchant Marine Act of 1920, commonly referred to as the Jones Act. The Jones Act requires that vessels engaged in coastwise trade to carry cargo between U.S. ports be owned and operated by U.S. citizens. To ensure that we are determined to be a U.S. citizen as defined under these laws, our certificate of incorporation contains certain restrictions on the ownership of our capital stock by foreigners and establishes certain mechanisms to maintain compliance with these laws. If we are determined at any time not to be in compliance with these citizenship requirements, our vessels would become ineligible to engage in the coastwise trade in U.S. domestic waters, and our business and operating results would be adversely affected. OUR BUSINESS INVOLVES MANY OPERATING RISKS THAT MAY DISRUPT OUR BUSINESS OR OTHERWISE RESULT IN SUBSTANTIAL LOSSES, AND INSURANCE MAY BE UNAVAILABLE OR INADEQUATE TO PROTECT US AGAINST THESE RISKS. Tugs, tank barges and OSVs are subject to operating risks such as catastrophic marine disaster, adverse weather and sea conditions, mechanical failure, collisions, oil and hazardous substance spills, navigation errors, acts of God, war and terrorism. The occurrence of any of these events may result in damage to or loss of our vessels and their tow or cargo or other property and injury to passengers and personnel. If any of these events were to occur, we could be exposed to liability for resulting damages. Affected vessels may also be removed from service and thus be unavailable for income-generating activity. While we believe our insurance coverage is at adequate levels and insures us against risks that are customary in the industry, we may be unable to renew such coverage in the future at commercially reasonable rates. Moreover, existing or future coverage may not be sufficient to cover claims that may arise. THE LOSS OF OUR CONTRACT OF AFFREIGHTMENT WITH AMERADA HESS CORPORATION OR THE EARLY TERMINATION OF ANY CONTRACTS ON OUR OSVS COULD HAVE AN ADVERSE EFFECT ON OUR OPERATIONS. The revenues we derived from our long-term contract of affreightment with Amerada Hess for June through December 2001, which was the first seven months that the contract was in effect, constituted more than 10% of our total revenues for such period. Under the terms of the contract of affreightment, we are required to meet certain performance criteria and, if we fail to meet such criteria, Amerada Hess would be entitled to terminate the contract. We can provide no assurance that we will be able to fulfill our performance obligations under the contract of affreightment, and a decision by Amerada Hess to terminate the contract of affreightment could adversely affect our financial condition and results of operations. Our contract of affreightment provides for minimum annual cargo volume to be transported and allows Amerada Hess to reduce its minimum commitment, subject to a significant adjustment penalty. Most of the contracts for our OSVs contain early termination options in favor of the customer; however, some have substantial early termination penalties designed to discourage the customers from exercising such options. We cannot assure that our customers would not choose to exercise their termination rights in spite of such penalties. Any such early termination could adversely affect our financial condition and results of operations. 11

FUTURE RESULTS OF OPERATIONS DEPEND ON THE LONG-TERM FINANCIAL STABILITY OF OUR CUSTOMERS. Many of the contracts we enter into for our OSVs are full utilization contracts with initial terms ranging from one to five years. We enter into such long-term contracts with our customers based on a credit assessment at the time of execution. Our financial condition in any period may therefore depend on the long-term stability and creditworthiness of our customers. We can provide no assurance that our customers will fulfill their obligations under our long-term contracts and the insolvency or other failure of a customer to fulfill its obligations under such contract could adversely affect our financial condition and results of operations. WE HAVE HIGH LEVELS OF FIXED COSTS THAT WILL BE INCURRED REGARDLESS OF OUR LEVEL OF BUSINESS ACTIVITY. Our business has high fixed costs, and downtime or low productivity due to reduced demand, weather interruptions or other causes could have a significant negative effect on our operating results. WE MAY BE UNABLE TO ATTRACT AND RETAIN QUALIFIED, SKILLED EMPLOYEES NECESSARY TO OPERATE OUR BUSINESS. Our success depends in large part on our ability to attract and retain highly skilled and qualified personnel. Our inability to hire, train and retain a sufficient number of qualified employees in the future could impair our ability to manage and maintain our business. We require skilled employees who can perform physically demanding work. As a result of the volatility of the oil and gas industry and the demanding nature of the work, potential employees may choose to pursue employment in fields that offer a more desirable work environment at wage rates that are competitive with ours. With a reduced pool of workers, it is possible that we will have to raise wage rates to attract workers from other fields and to retain our current employees. If we are not able to increase our service rates to our customers to compensate for wage-rate increases, our operating results may be adversely affected. OUR EMPLOYEES ARE COVERED BY FEDERAL LAWS THAT MAY SUBJECT US TO JOB-RELATED CLAIMS IN ADDITION TO THOSE PROVIDED BY STATE LAWS. Some of our employees are covered by provisions of the Jones Act, the Death on the High Seas Act and general maritime law. These laws typically operate to make liability limits established by state workers' compensation laws inapplicable to these employees and to permit these employees and their representatives to pursue actions against employers for job-related injuries in federal courts. Because we are not generally protected by the limits imposed by state workers' compensation statutes, we may have greater exposure for any claims made by these employees. OUR SUCCESS DEPENDS ON KEY MEMBERS OF OUR MANAGEMENT, THE LOSS OF WHOM COULD DISRUPT OUR BUSINESS OPERATIONS. We depend to a large extent on the efforts and continued employment of our executive officers and key management personnel. We do not maintain key-man insurance. The loss of services of one or more of our executive officers or key management personnel could have a negative impact on our operations. 12

RESTRICTIONS CONTAINED IN THE INDENTURE GOVERNING OUR 10 5/8% SENIOR NOTES AND IN THE AGREEMENT GOVERNING OUR REVOLVING CREDIT FACILITY MAY LIMIT OUR ABILITY TO OBTAIN ADDITIONAL FINANCING, TO PURSUE OTHER BUSINESS OPPORTUNITIES AND TO PAY DIVIDENDS. Covenants contained in the indenture governing our 10 5/8% senior notes and in the agreement governing our revolving credit facility require us to meet certain financial tests, which may limit: - our flexibility in planning for, and reacting to, changes in our business; - our ability to dispose of assets, withstand current or future economic or industry downturns and compete with others in our industry for strategic opportunities; - our ability to obtain additional financing for working capital, capital expenditures, acquisitions, general corporate and other purposes; and - our ability to pay dividends, should we choose to do so in the future. RISKS RELATING TO THIS OFFERING OUR MANAGEMENT AND DIRECTORS WILL BENEFICIALLY OWN, CONTROL OR HAVE SUBSTANTIAL INFLUENCE OVER A SIGNIFICANT AMOUNT OF COMMON STOCK, GIVING THEM A CONTROLLING INFLUENCE OVER CORPORATE TRANSACTIONS AND OTHER MATTERS. THEIR INTERESTS MAY CONFLICT WITH YOURS, AND THE CONCENTRATION OF OWNERSHIP OF OUR COMMON STOCK BY SUCH STOCKHOLDERS WILL LIMIT THE INFLUENCE OF PUBLIC STOCKHOLDERS. Upon completion of this offering, our management, directors and their respective affiliates, will beneficially own, control or have substantial influence over approximately % of our outstanding common stock, approximately % if the underwriters exercise their over-allotment option in full. If these stockholders voted together as a group, they would have the ability to exert significant influence over our board of directors and its policies. These stockholders would, acting together, be able to control or substantially influence the outcome of stockholder votes, including votes concerning the election of directors, the adoption or amendment of provisions in our certificate of incorporation or bylaws and possible mergers, corporate control contests and other significant corporate transactions. This concentration of ownership may have the effect of delaying, deferring or preventing a change in control, a merger, consolidation, takeover or other business combination. This concentration of ownership could also discourage a potential acquirer from making a tender offer or otherwise attempting to obtain control of us, which could in turn have an adverse effect on the market price of our common stock. OUR STOCK PRICE MAY FLUCTUATE SIGNIFICANTLY FOLLOWING THIS OFFERING, AND YOU COULD LOSE ALL OR A PART OF YOUR INVESTMENT AS A RESULT. Prior to this offering there has been no public market for our common stock, and we cannot predict the extent to which investor interest in us will lead to the development or maintenance of an active trading market. You may not be able to resell your shares at or above the initial public offering price, which will be determined through negotiations among us and the underwriters and may not be indicative of prices that will prevail in the public trading market. The trading price of our common stock, and the price at which we may sell securities in the future, could be subject to significant fluctuations in response to: - government regulations; - the prices of oil and natural gas; - our operating results; - changes in earnings estimates by securities analysts or our ability to meet those estimates; 13

- news announcements regarding the oil and gas or related industries in general, our customers, our competitors or us; or - other factors beyond our control. The realization of any of the risks described in this section could cause the market price of our common stock to decline significantly. INVESTORS IN THIS OFFERING WILL SUFFER IMMEDIATE AND SUBSTANTIAL DILUTION. The initial public offering price of our common stock will be substantially higher than the net tangible book value per share of the common stock outstanding immediately after this offering. Therefore, if you purchase shares in this offering, you will incur immediate and substantial dilution based on net tangible book value per share. You will incur further dilution if outstanding options to purchase common stock are exercised. In addition, our certificate of incorporation allows us to issue significant numbers of additional shares. Any such issuance may significantly reduce your proportionate interest in our stock. FUTURE SALES OF OUR COMMON STOCK COULD ADVERSELY AFFECT ITS MARKET PRICE. Following this offering, we will have a large number of shares of common stock outstanding and available for resale beginning at various points in time in the future. Sales of a substantial number of shares of our common stock in the public market after this offering, or the possibility that these sales may occur, could cause the market price for our common stock to decline. These sales, or the possibility that these sales may occur, could also make it more difficult for us to sell our common stock or other equity securities in the future at a time and at a price that we deem appropriate. Our directors, executive officers and principal and selling stockholders, who collectively will own, control or have substantial influence over a total of shares of common stock ( shares if the underwriters' exercise their over-allotment option in full) following the completion of this offering, have agreed not to dispose of any shares of common stock, subject to limited exceptions, for a period of 180 days after the date of this prospectus, without the consent of the underwriters. PROVISIONS OF OUR CERTIFICATE OF INCORPORATION, BYLAWS, STOCKHOLDER RIGHTS PLAN AND DELAWARE LAW COULD DETER TAKEOVER ATTEMPTS. Our certificate of incorporation and bylaws and the Delaware corporations law contain provisions, and our board of directors has approved the form of a stockholder rights plan, that could have the effect of making it more difficult for a third party to acquire, or discourage a third party from attempting to acquire, control of us. These provisions could limit the price that investors might be willing to pay in the future for shares of our common stock. 14

USE OF PROCEEDS We estimate that we will receive net proceeds from the sale of shares in this offering, after deducting offering expenses, of approximately $ million. If the underwriters' over-allotment option is exercised to purchase additional shares from us, we estimate that we will receive up to an additional $ million. We intend to use a portion of these proceeds, along with cash on hand, cash flow from operations and amounts available under our revolving credit facility, to fund the costs of the construction of the first four offshore supply vessels to be delivered under our current newbuild program, which we expect to be approximately $53 million. We will use the remainder of these funds to fund the costs of the construction of the other four offshore supply vessels to be built under our current newbuild program, possible future acquisitions, the retrofit of existing vessels or construction of additional vessels, and for general corporate purposes. We do not currently have any agreements or understandings with respect to any specific acquisition target. We will not receive any proceeds from the sale of shares by the selling stockholders. DIVIDEND POLICY We currently intend to retain any future earnings to finance the growth, development and expansion of our business. Accordingly, we do not currently intend to declare or pay any dividends on our common stock for the foreseeable future. The declaration, payment and amount of future dividends, if any, will be at the sole discretion of our Board of Directors after taking into account various factors, including, among others, our financial condition, results of operations, cash flows from operations, current and anticipated capital requirements and expansion plans, the income tax laws then in effect and the requirements of Delaware law. In addition, the indenture governing our 10 5/8% senior notes and the agreement governing our revolving credit facility include restrictions on our ability to pay cash dividends without meeting certain financial ratios or obtaining the consent of the lenders. 15

CAPITALIZATION The following table sets forth our consolidated cash and cash equivalents and capitalization as of March 31, 2002: - on a historical basis; and - as adjusted to reflect our sale of shares of common stock in this offering at an assumed initial public offering price of $ per share, after deducting underwriting discounts and commissions and our estimated offering expenses of $ . The information in this table is unaudited. This table should be read in conjunction with our historical consolidated financial statements and the notes to those statements included in this prospectus.

The information set forth above does not include 2,032,236 shares of our common stock issuable as of March 31, 2002, upon exercise of options previously granted to employees and non-employee directors at a weighted average price of $2.53 and 1,467,764 additional shares of our common stock reserved as of March 31, 2002, for issuance under our Incentive Compensation Plan, and also assumes that the underwriters do not purchase additional shares of common stock from us in this offering to cover over-allotments. 16

DILUTION Our net tangible book value as of March 31, 2002, was approximately $ million or $ per share. Net tangible book value per share represents our tangible net worth (tangible assets less total liabilities) divided by the total number of outstanding shares of our common stock. Dilution in net tangible book value per share represents the difference between the amount per share that investors will pay in this offering and the net tangible book value per share immediately afterwards. After giving effect to our receipt of $ million of estimated net proceeds from our sale of shares of our common stock in this offering at an assumed price of $ per share after deducting the estimated underwriting fees and estimated expenses of this offering, our adjusted net tangible book value as of March 31, 2002 would have been $ million or $ per share. This represents an immediate increase in our net tangible book value of $ per share to existing shareholders and an immediate dilution of $ per share to new investors purchasing our common stock in this offering. The following table illustrates this per share dilution to new investors purchasing our common stock in this offering:

Assumed public offering price per share..................... $ -------- Net tangible book value per share as of March 31, 2002...... -------- Increase per share attributable to new investors............ -------- Adjusted net tangible book value per share after this offering.................................................. -------- Dilution per share to new investors......................... $ ========
The table above assumes no issuance of shares under options outstanding as of March 31, 2002. Upon completion of this offering, 1,962,236 shares of our common stock will be issuable upon the exercise of options granted under our Incentive Compensation Plan at exercise prices ranging from $1.85 to $2.65 per share. Of these shares, 1,635,101 will be issuable under options that will be exercisable upon completion of this offering, with the remaining 327,135 becoming issuable at various intervals in the future based on remaining option vesting schedules. Please read "Management -- Option Grants" and "Principal and Selling Stockholders" for more information regarding outstanding options to purchase our common stock. If the 1,635,101 shares subject to options that will be exercisable upon completion of this offering were included in the above calculations, the dilution per share to new investors would be $ , and if all 1,962,236 shares subject to options outstanding upon completion of this offering were included in the above calculations, the dilution per share to new investors would be $ . The following table illustrates, on an as adjusted basis as of March 31, 2002, the difference between the number of shares of common stock purchased from us, the total consideration paid to us and the average price paid by existing shareholders and by the new investors purchasing shares of common stock in this offering, before deduction of estimated underwriting fees and estimated expenses of this offering payable by us.

- --------------- (1) Represents non-cash adjustment to interest expense resulting from warrants that provide for put options being accounted for at their fair value. A company whose capital stock is publicly traded is required to account for warrants that contain put options at their fair value and to report the changes as interest expense. (2) Net of other income and expenses. (3) A non-cash extraordinary loss of $1,964, net of taxes, was incurred during 2001 resulting from the early extinguishment of debt. This extraordinary item relates to the write off of deferred financing costs upon the refinancing of all our debt through the issuance of our 10 5/8% senior notes in July 2001. (4) Excludes a net write off of $108 ($0.01 basic and diluted per share of common stock) related to a cumulative effect of change in accounting principle for start-up costs. (5) Excludes original issue discount associated with our senior notes in the amount of $3,024 and $2,890 as of December 31, 2001 and March 31, 2002, respectively. (6) EBITDA is earnings before interest expense, other (expense) income, provision for income taxes, depreciation and amortization. EBITDA is presented as it is commonly used by certain investors to analyze and compare operating performance and to determine a company's ability to service or incur debt. EBITDA should not be considered in isolation or as a substitute for net income, cash flow or other income or cash flow data or as a measure of a company's profitability or liquidity and is not a measure calculated in accordance with generally accepted accounting principles. EBITDA is not necessarily comparable with similarly titled measures reported by other companies. (7) Calculated as EBITDA, as defined in footnote (6) above, divided by cash interest paid. (8) Utilization rates are average rates based on a 365-day year. Vessels are considered utilized when they are generating revenues. (9) Average dayrates represent average revenue per day, which includes charter hire and brokerage revenue, based on the number of days during the period that the OSVs generated revenue. (10) Average dayrates represent average revenue per day, including time charters, brokerage revenue, revenues generated on a per-barrel-transported basis, demurrage, shipdocking and fuel surcharge revenue, based on the number of days during the period that the tank barges generated revenue. For purposes of brokerage arrangements, this calculation excludes that portion of revenue that constitutes a "pass-through" to the customer of the cost of in-chartering third party equipment. 19

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following management's discussion and analysis should be read in conjunction with our historical consolidated financial statements and the notes to those statements included elsewhere in this prospectus. This discussion contains forward-looking statements that reflect our current views with respect to future events and financial performance. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, such as those set forth under "Risk Factors" and elsewhere in this prospectus. GENERAL We own and operate deepwater OSVs in the Gulf of Mexico and ocean-going tugs and tank barges in the northeastern United States, primarily New York Harbor, and in Puerto Rico. We charter our OSVs on a dayrate basis, under which the customer pays us a specified dollar amount for each day during the term of the contract, pursuant to either fixed time charters or spot market charters. A fixed time charter is a contract with a term of at least one year in which the charterer obtains the right to direct the movements and utilization of the vessel in exchange for payment of a specified dayrate, generally paid monthly, but the vessel owner retains operational control over the vessel. Typically, the owner fully equips the vessel and is responsible for normal operating expenses, repairs, wages and insurance, while the charterer is responsible for voyage expenses, such as fuel, port and stevedoring expenses. Spot market charters in the OSV industry are generally time charter contracts with either relatively short, indefinite terms or fixed terms of less than one year. Generally, the vessel owner absorbs crew, insurance and repair and maintenance costs in connection with operation of OSVs pursuant to spot market charters and customers absorb other direct operating costs. All of our OSVs are currently operating under time charters, including six that are chartered under contracts with expiration dates ranging from April 2003 through November 2006. Our long-term contracts for our OSVs are consistent with those used in the industry and are either fixed for a term of months or years or are tied to the duration of a long-term contract for a drilling rig for which the vessel provides services. These contracts generally contain, among others, provisions governing insurance, reciprocal indemnifications, performance requirements and, in certain instances, dayrate escalation terms and renewal options. While OSVs service existing oil and gas production platforms as well as exploration and development activities, incremental OSV demand depends primarily upon the level of drilling activity, which can be influenced by a number of factors, including oil and natural gas prices and drilling budgets of exploration and production companies. As a result, utilization and dayrates have historically been tied to oil and natural gas prices and drilling activity, although the greater investment of time and expense associated with deepwater production and the consequent long-term nature of deepwater OSV contracts have diminished the significance of this relationship. Generally, we operate an ocean-going tug and tank barge together as a "tow" to transport petroleum products between U.S. ports and along the coast of Puerto Rico. We operate our tugs and tank barges under fixed time charters, spot market charters, contracts of affreightment and consecutive voyage contracts. Spot market charters in the tug and tank barge industry are generally single-voyage contracts of affreightment or time charter contracts with terms of less than one year. A consecutive voyage contract is a contract for the transportation of cargo for a specified number of voyages between designated ports over a fixed period of time under which we are paid based on the volume of products we deliver per voyage. Under consecutive voyage contracts, in addition to earning revenues for volumes delivered, we earn a standby hourly rate between charters. One of our tank barges has been chartered to a third party under a bareboat charter. A bareboat charter is a "net lease" in which the charterer takes full operational control over the vessel for a specified period of time for a specified daily rate that is generally paid 20

monthly to the vessel owner. The bareboat charterer is solely responsible for the operation and management of the vessel and must provide its own crew and pay all operating and voyage expenses. The primary drivers of demand for our tug and tank barge services are population growth, the strength of the United States economy and changes in weather patterns that affect consumption of heating oil and gasoline. The tug and tank barge market, in general, is marked by steady demand over time. We believe that demand for refined petroleum products and crude oil will remain steady or gradually increase for the foreseeable future. Our operating costs are primarily a function of fleet size and utilization levels. The most significant direct operating costs are wages paid to vessel crews, maintenance and repairs and marine insurance. Because most of these expenses remain payable regardless of vessel utilization, our direct operating costs as a percentage of revenues may fluctuate considerably with changes in dayrates and utilization. In addition to the operating costs described above, we incur fixed charges related to the depreciation of our fleet and costs for routine drydock inspections and maintenance and repairs necessary to ensure compliance with applicable regulations and to maintain certifications for our vessels with the U.S. Coast Guard and various classification societies. The aggregate number of drydockings and other repairs undertaken in a given period determines the level of maintenance and repair expenses and marine inspection amortization charges. We generally capitalize costs incurred for drydock inspection and regulatory compliance and amortize such costs over the period between such drydockings, typically 30 or 60 months. Applicable maritime regulations require us to drydock our vessels twice in a five-year period for inspection and routine maintenance and repair. If we undertake a large number of drydockings in a particular fiscal period, comparative results may be affected. CRITICAL ACCOUNTING POLICIES The accounting treatment of a particular transaction is specifically dictated by accounting principles generally accepted in the United States. In preparing our financial statements, we are required to make estimates, judgments and assumptions that we believe are reasonable based upon information available. We base our estimates and judgments on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions and conditions. We believe that of our significant accounting policies discussed in Note 2 to our consolidated financial statements beginning on page F-15, the following may involve a higher degree of judgment. Purchase Accounting. Purchase accounting requires extensive use of estimates and judgments to allocate the cost of an acquired enterprise to the assets acquired and liabilities assumed. The cost of each acquired operation is allocated to the assets acquired and liabilities assumed based on their estimated fair values. These estimates are revised during an allocation period as necessary when, and if, information becomes available to further define and quantify the value of the assets acquired and liabilities assumed. For example, costs related to the recertification of acquired vessels that are drydocked within the allocation period immediately following the acquisition of such vessels adjust the value of the vessels acquired and the liabilities assumed related to the drydocking. The adjusted basis of the vessel is depreciated over the estimated useful lives of the vessels. The allocation period does not exceed beyond one year from the date of the acquisition. To the extent additional information to refine the original allocation becomes available during the allocation period, the allocation of the purchase price is adjusted. For example, if an acquired vessel is subsequently disposed of within the allocation period, the sales price of the vessel is used to adjust the original assigned value to the vessel at the date of acquisition such that no gain or loss would be recognized upon disposition during the 21

allocation period. Should information become available after the allocation period, those items are reflected in operating results. Carrying Value of Vessels. We depreciate our tugs, tank barges, and OSVs over estimated useful lives of 14 to 25 years, 3 to 18 years and 25 years, respectively. The economic useful lives used for tank barges is based on their classification under the Oil Pollution Act of 1990, or OPA 90. In assigning depreciable lives to these assets, we have considered the effects of both physical deterioration largely caused by wear and tear due to operating use and other economic and regulatory factors that could impact commercial viability. To date, our experience confirms that these policies are reasonable, although there may be events or changes in circumstances in the future that indicate the recoverability of the carrying amount of a vessel might not be possible. Examples of events or changes in circumstances that could indicate that the recoverability of a vessel's carrying amount should be assessed might include a change in regulations such as OPA 90, a significant decrease in the market value of a vessel and current period operating or cash flow losses combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with a vessel. If events or changes in circumstances as set forth above indicate that a vessel's carrying amount may not be recoverable, we would then be required to estimate the undiscounted future cash flows expected to result from the use of the vessel and its eventual disposition. If the sum of the expected undiscounted future cash flows is less than the carrying amount of the vessel, we would be required to recognize an impairment loss. Recertification Costs. Our tugs, tank barges and OSVs are required by regulation to be recertified after certain periods of time. These recertification costs are incurred while the vessel is in drydock where other routine repairs and maintenance are performed and, at times, major replacements and improvements are performed. Routine repairs and maintenance are expensed as incurred. Recertification costs are generally deferred and amortized over the length of time in which the recertification is expected to last, which is generally 30 to 60 months. Major replacements and improvements which extend the vessel's economic useful life or functional operating capability are capitalized and depreciated over the vessel's remaining economic useful life. Inherent in this process are estimates we make regarding the specific cost incurred and the period that the incurred cost will benefit. RESULTS OF OPERATIONS The table below sets forth, by segment, the average dayrates and utilization rates for our vessels and the average number of vessels owned during the periods indicated. These OSVs and tug and tank barges generate substantially all of our revenues and operating profit.

- --------------- (1) Includes only seven months of operations of the nine tugs and nine tank barges acquired from the Spentonbush/Red Star Group effective May 31, 2001, only eight months of operations from the HOS Innovator, delivered in April 2001, and only two months of operations from the BJ Blue Ray, delivered in November 2001. (2) Includes only one month of operations from the HOS Dominator, delivered in February 2002. (3) Utilization rates are average rates based on a 365-day year. Vessels are considered utilized when they are generating revenues. (4) Average dayrates represent average revenue per day, which includes charter hire and brokerage revenue, based on the number of days during the period that the OSVs generated revenue. (5) Average dayrates represent average revenue per day, including time charters, brokerage revenue, revenues generated on a per-barrel-transported basis, demurrage, shipdocking and fuel surcharge revenue, based on the number of days during the period that the tank barges generated revenue. For purposes of brokerage arrangements, this calculation excludes that portion of revenue that constitutes a "pass-through" to the customer of the cost of in-chartering third party equipment. THREE MONTHS ENDED MARCH 31, 2002 COMPARED TO THREE MONTHS ENDED MARCH 31, 2001 Revenues. Revenues were $22.7 million for the three months ended March 31, 2002, as compared to $10.4 million for the same period in 2001, an increase of $12.3 million or 118.3%. This increase in revenue was primarily the result of the significant increase in the size of our fleet since April 2001. Our operating fleet grew from 18 vessels at the end of the first three months of 2001 to 39 vessels at the end of the first three months of 2002. The additional revenues generated by the 21 new vessels accounted for approximately $11.0 million of the $12.3 million increase in revenues in the first three months of 2002 compared to the same period last year. The balance of the increase in revenue of approximately $1.3 million was derived from our 18 vessels that were in service during each of the first three months of 2001 and 2002. Our OSVs operating in the first three months of both 2002 and 2001 earned higher average dayrates in the first three months of 2002 than in the same period of 2001. Average dayrates for such OSVs increased 18.4% due to increased exploration and production activity in the deepwater Gulf of Mexico. Our tugs and tank barges operating in the first three months of 2002 and 2001 had higher average utilization in the first three months of 2002 than in the same period of 2001. Average tank barge dayrate for such vessels increased 21.4% due to a change in mix of vessels from contracts of affreightment to time charter, combined with fewer days out of service for drydock and repairs in the first three months of 2002 compared to the same period of 2001. Revenues from our OSV segment totaled $9.8 million for the three months ended March 31, 2002, as compared to $6.3 million for the same period in 2001, an increase of $3.5 million or 55.6%. The increase in the OSV segment revenue was primarily due to higher average dayrates and the addition of three deepwater OSVs since April 2001. Our utilization rate was 95.9% in the first three months of 2002 compared to 98.7% in the same period of 2001. The slight decrease in utilization was primarily due to two scheduled drydockings. Our OSV average dayrate was $12,012 in the first three months of 2002 compared to $10,147 in the same period of 2001, an increase of $1,865 or 18.4%. The increase in average dayrates was due to a combination of continued high levels of deepwater drilling, construction and field development activity in the Gulf of Mexico and the addition to our fleet of the larger, newly constructed 240 Class HOS Innovator on April 28, 2001, the 265 Class BJ Blue Ray on November 6, 2001 and the 240 Class HOS Dominator on February 28, 2002. Each vessel commanded higher dayrates than our 200 Class OSVs. Revenues from our tug and tank barge segment totaled $13.0 million for the three months ended March 31, 2002 as compared to $4.1 million for the same period in 2001, an increase of $8.9 million or 217.1%. The tug and tank barge segment revenue increase was primarily due to increased utilization and the revenues generated by nine tugs and nine tank barges acquired on May 31, 2001. The acquisition increased fleet capacity in barrels from 451,655 to 1,130,727 an 23

increase of 150%. Revenues for the first three months of 2002 included $1.1 million that was attributable to the "pass-through" to the customer of the cost of in-chartering third party equipment. There were no such "pass-through" revenues in the first three months of 2001. Our utilization rate increased to 86.9% for the three months ended March 31, 2002 compared to 83.3% for the same period in 2001. The increase in utilization was primarily the result of a change from vessels operating under contracts of affreightment to time charters, as well as the vessels out of service for repairs fewer days in the first three months of 2002 as compared to the same period in 2001. Our average dayrate increased to $9,500 for the first three months of 2002 compared to $7,824 for the same period of 2001. We believe the increase in dayrates since the first three months of last year is reflective of the early effects of the Oil Pollution Act of 1990. Operating Expense. Our operating expense, including depreciation and amortization, increased to $10.6 million for the three months ended March 31, 2002 as compared to $5.1 million in the same period in 2001, an increase of $5.5 million or 107.8%. The increase in operating expense resulted primarily from the addition of 21 vessels to the OSV and tank barge fleets since the first three months of 2001. Operating expense for our OSV segment increased to $3.7 million in the first three months of 2002 compared to $2.4 million in the same period of 2001, an increase of $1.3 million or 54.2%. This increase was primarily the result of the HOS Innovator and BJ Blue Ray being in service for all of the first three months of 2002 and the HOS Dominator being in service for a portion of the first three months of 2002, but not in service during the same period of 2001. Daily operating costs per vessel for the first three months of 2002 increased over the same period of 2001, primarily due to the higher costs of operating larger vessels, including increased manning requirements, in the first three months of 2002. Operating expense for our tug and tank barge segment was $6.9 million for the first three months of 2002 compared to $2.7 million for the same period of 2001, an increase of $4.2 million or 155.6%. The operating expense increase was primarily the result of the addition of nine tugs and nine tank barges on May 31, 2001. Operating expense for the first three months of 2002 included $1.1 million of the cost of in-chartering third party equipment that was "passed through" to the customer. There were no such costs that were "passed through to the customer in the first three months of 2001. Daily operating costs per vessel, excluding "pass-through" operating expenses related to in-chartering of third party equipment, for the first three months of 2002 remained fairly consistent with the same period of 2001. General and Administrative Expense. Our general and administrative expense was $2.8 million for the first three months of 2002 as compared to $1.3 million for the same period of 2001, an increase of $1.5 million. This increase primarily resulted from increased overhead relating to the nine tugs and nine tank barges acquired on May 31, 2001 and new costs associated with compliance with our reporting obligations under the federal securities laws. As discussed in Note 2 to our consolidated financial statements contained herein, we adopted Statement of Financial Accounting Standards No. 142 effective January 1, 2002 and, accordingly, we have ceased amortizing goodwill. General and administrative expense for the first three months of 2001 included goodwill amortization of less than $0.1 million. Interest Expense. Interest expense was $3.9 million for the first three months of 2002 compared to $1.6 million in the same period of 2001, an increase of $2.3 million or 143.8%. The increase in interest expense resulted from the refinancing of all of our conventional floating rate debt through the issuance of senior notes in July 2001 with a higher fixed rate, and a higher average balance of debt outstanding in the 2002 period. This increase was offset by the capitalization of interest costs relating to new construction of approximately $1.0 million in the first three months of 2002 compared to $0.5 million in the same period of 2001. The increase in capitalized construction period interest was primarily due to a higher effective interest rate and a 24

higher average balance of construction in progress outstanding during the first three months of 2002. Interest Income. Interest income was $0.2 million for the first three months of 2002 compared to $0.4 million for the same period of 2001, a decrease of $0.2 million or 50.0%. This decrease in interest income resulted from substantially higher interest rates being earned during the 2001 period, even though cash balances invested during the 2002 period were significantly higher than the 2001 period, due to the excess proceeds of the senior notes offering being available for investment since the July 2001 offering. Income Tax Expense. Our income tax expense for the first three months for each of 2002 and 2001 primarily consisted of deferred taxes due to our federal net operating loss carryforwards to offset future taxable income. In addition, we expect to generate additional federal tax benefits due to our use of accelerated tax depreciation with respect to new vessels. Our use of these net operating losses and additional tax benefits may be limited due to U.S. tax laws. Based on the age and composition of our current fleet, however, we expect to pay a lower than normal amount of federal income taxes over the next five years. YEAR ENDED DECEMBER 31, 2001 COMPARED TO YEAR ENDED DECEMBER 31, 2000 Revenues. Revenues were $68.8 million for the year ended December 31, 2001, as compared to $36.1 million in 2000, an increase of $32.7 million or 90.6%. This increase was primarily attributable to our OSV segment, which continued to experience strong demand for our vessels, and the revenues generated by the additional tugs and tank barges acquired on May 31, 2001. Revenues from our OSV segment increased to $33.6 million in 2001 as compared to $19.6 million in 2000, an increase of $14.0 million or 71.4%. The primary reasons for the increase in revenue from this segment were a 40.7% increase in average dayrates, a 5.7% increase in utilization and the addition, during 2001, of two newly constructed OSVs, one in late April and the other in early November. Our utilization rate for our OSVs was 99.1% for 2001 compared to 93.4% in 2000 as a result of higher demand for deepwater drilling, construction and field development activity in the Gulf of Mexico. Our OSV average dayrate was $11,872 for 2001 compared to $8,435 in 2000, an increase of $3,437 or 40.7%. The increase in average dayrates was due to a combination of higher demand and the addition to our fleet of the larger, newly constructed 240 Class HOS Innovator on April 28, 2001 and the 265 Class BJ Blue Ray on November 6, 2001. Each vessel operated at higher dayrates than our 200 Class OSVs. Revenues from our tug and tank barge segment totaled $35.2 million for 2001 as compared to $16.5 million in 2000, an increase of $18.7 million or 113.3%. This segment revenue increase was primarily due to increased utilization and the acquisition of nine tugs and nine tank barges on May 31, 2001, which increased fleet capacity from 451,655 barrels to 1,130,727 barrels. Our utilization rate for our tugs and tank barges increased to 84.4% for 2001 compared to 71.4% in 2000. The increase in utilization was primarily the result of a change from vessels operating under contracts of affreightment to time charters, combined with the vessels being out of service for repairs fewer days in 2001 as compared to 2000. Our average dayrate increased to $9,306 in 2001 compared to $8,982 in 2000, an increase of $324 per day or 3.6%. Operating Expense. Our operating expense, including depreciation and amortization, increased to $32.4 million for 2001 as compared to $20.4 million in 2000, an increase of $12.0 million or 58.8%. The increase in total operating expense resulted primarily from the addition of vessels to the OSV and tank barge fleets during 2001. Daily operating expenses per vessel in both the OSV segment and the tug and tank barge segment remained fairly constant. Operating expense for our OSV segment increased $5.9 million or 63.4% in 2001 to $15.2 million compared to $9.3 million in 2000. This increase was primarily the result of the HOS 25

Cornerstone being in service for all of 2001, but only a portion of 2000 and the HOS Innovator and BJ Blue Ray being in service for a portion of 2001 but not in service during 2000. Operating expense for our tug and tank barge segment was $25.7 million for 2001 compared to $11.1 million in 2000, an increase of $14.6 million or 131.5%. The operating expense increase resulted primarily from our acquisition of nine tugs and nine tank barges on May 31, 2001. General and Administrative Expense. Our general and administrative expense was $8.5 million for 2001 as compared to $3.4 million of 2000, an increase of $5.1 million. This increase primarily resulted from increased overhead relating to the nine tugs and nine tank barges acquired on May 31, 2001, new costs associated with compliance with our reporting obligations under the federal securities laws and an increase in profit-based incentive bonus compensation accruals as our profitability increased. Interest Expense. Interest expense from debt obligations was $10.7 million in 2001 compared to $8.2 million in 2000, an increase of $2.5 million or 30.5%. This increase in interest expense from debt obligations resulted from the refinancing of all of our conventional floating rate debt through the issuance of our senior notes in July 2001 with a higher fixed rate and average debt outstanding in the 2001 period. This increase was offset by capitalized interest in 2001 due to the construction in progress of six OSVs compared to one vessel under construction in 2000. Non cash adjustments to interest expense reflects fair value adjustments to warrants having put options. The adjustment for 2001 was $2,952 compared to $7,262 in 2000, a decrease of $4,310 or 59.4%. Interest Income. Interest income was $1.5 million in 2001 compared to $0.3 million in 2000, an increase of $1.2 million or 400%. This increase in interest income resulted from substantially higher cash balances invested during the 2001 period resulting from the excess proceeds of the senior notes offering being available for investment after the refinancing. Income Tax Expense. Our effective income tax provision for 2001 compared to 2000 was lower primarily due to the impact of non-deductible interest expense resulting from fair value adjustments for warrants with put options, which was $4,310 lower in 2001 than in 2000. Extraordinary Loss. A non-cash extraordinary loss of $2.0 million, net of taxes, was incurred during 2001 resulting from the early extinguishment of debt. This extraordinary item relates to the write-off of deferred financing costs upon the refinancing of all our debt through the issuance of our 10 5/8% senior notes in July 2001. For more information, please read "Recent Accounting Pronouncements" below. YEAR ENDED DECEMBER 31, 2000 COMPARED TO YEAR ENDED DECEMBER 31, 1999 Revenues. Revenues were $36.1 million in the year ended December 31, 2000 compared to $25.7 million in the year ended December 31, 1999, an increase of $10.4 million or 40.5%. Substantially all of this increase was attributable to our OSV fleet which operated at substantially higher dayrates in 2000 than in 1999. Revenues from our OSV segment totaled $19.6 million in 2000 compared to $9.5 million in 1999, an increase of $10.1 million or 106.3%. The increase in our revenues in 2000 reflected the continued growth of our OSV fleet through the construction of six new OSVs, five of which were delivered at various points during 1999 and one of which was delivered in early 2000. In addition to the impact of new vessel deliveries, average dayrates in 2000 were $8,435 as compared to $6,724 in 1999, an increase of $1,711 per day or 25.4%. This increase reflected the continuing increase in demand for OSVs to support deepwater oil and gas exploration, drilling and production in the Gulf of Mexico, combined with the higher dayrates attributable to two 26

240 Class vessels entering the fleet in late 1999 and early 2000. Our average utilization rate was approximately 93% in each year. Revenues from our tug and tank barge segment totaled $16.5 million in 2000 compared to $16.2 million in 1999, an increase of $0.3 million or 1.9%. Our utilization rate decreased to 71.4% in 2000 from 73.9% in 1999, primarily due to the removal of vessels from service for scheduled maintenance. Although vessel utilization decreased, our average dayrate increased to $8,982 in 2000 from $8,482 in 1999, an increase of $500 per day worked or 5.9%. Operating Expense. Our operating expense, including depreciation and amortization, increased from $16.9 million in 1999 to $20.4 million in 2000, an increase of $3.5 million or 20.7%. Daily operating expenses per vessel in both the OSV segment and the tug and tank barge segment remained fairly constant. Changes in operating expenses resulted primarily from changes in the number of vessels operating in the fleet and fluctuations in direct costs of sales that are either reimbursed by customers or absorbed as an operating expense for the vessel. Operating expense for our OSV segment increased $4.0 million in 2000 to $9.3 million compared to $5.3 million in 1999. This increase resulted from the inclusion in 2000 of vessels added to our fleet at various times in 1999 and early 2000. Operating expense for our tug and tank barge segment decreased $0.9 million or 7.5% in 2000 to $11.1 million compared to $12.0 million in 1999. The operating expense reduction was the result of changing certain contracts from contracts of affreightment to time charters for three tows and having fewer overall contracts of affreightment and more time charters. The result was a daily operating cost of $4,340 per day in 2000 compared to $4,648 per day in 1999, a decrease of $308 per day or 6.6%. General and Administrative Expense. Our general and administrative expense was $3.4 million in 2000 compared to $2.9 million in 1999, an increase of $0.5 million or 17.2%. This increase primarily resulted from an increase in shore-based personnel and associated compensation costs as OSV fleet operations expanded and increased accruals under our profit-based incentive bonus compensation program as our profitability increased. Interest Expense. Interest expense from debt obligations was $8.2 million in 2000 compared to $5.3 million in 1999, an increase of $2.9 million or 54.7%. Interest expense from debt obligations increased as vessels were delivered in 1998, 1999 and 2000 due to conversion from construction interest, which was capitalized, to interest expense under term financing. The financing of the HOS Deepwater and the HOS Cornerstone under one of our former credit facilities increased our debt balances, leading to increased interest expense. Non cash adjustments to interest expense resulting from fair value adjustments to warrants was $7,262 in 2000 compared to $2,262 in 1999 representing a $5,000 increase or 221.0%. Income Tax Expense. Our effective income tax provision for 2000 compared to 1999 was higher primarily due to the impact of non-deductible interest expense resulting from fair value adjustments to warrants with put options, which was $5,000 higher in 2000 than 1999. LIQUIDITY AND CAPITAL RESOURCES We need capital to fund ongoing operations, capital expenditures for the construction of new vessels, acquisitions and debt service. We have historically financed our capital needs with cash flow from operations, issuances of equity and debt securities and borrowings under our credit facilities. Net cash provided by operating activities was $1.9 million in 1999, $5.7 million in 2000, $33.3 million in 2001 and $1.0 million for the first three months of 2002. Changes in cash flow from operating activities are principally the result of higher income from operations after considering increases in depreciation and amortization due to the significant expansion of our 27

vessel fleet, offset by changes in our net working capital, including a $5.1 million decrease in accrued interest expense related to our senior notes. Net cash used in investing activities was $42.3 million in 1999, $15.3 million in 2000, $88.3 million in 2001 and $11.8 million for the first three months of 2002. Net cash used in investing activities was primarily the result of new vessel construction and acquisitions. Also included in these invested cash amounts are drydocking expenditures of $1.0 million in 1999 and $1.7 million in both 2000 and 2001, which were predominately related to recertification of vessels not recently acquired, and of $0.5 million in the first three months of 2002, which were related to recertification of vessels acquired on May 31, 2001. Net cash provided by financing activities was $43.4 million in 1999, $36.4 million in 2000 and $75.2 million in 2001 and $0.1 million in the first three months of 2002. Net cash provided by financing activities was primarily the result of issuances of equity and senior notes and borrowings under our former credit facilities offset in part by the repayment in full of such credit facilities. On December 31, 2001, two of our subsidiaries, Hornbeck Offshore Services, LLC and Hornbeck Offshore Transportation, LLC (formerly known as LEEVAC Marine, LLC), entered into a new $50.0 million three-year senior secured revolving line of credit. Pursuant to the terms of the revolver, our borrowings under this facility will initially be limited to $25.0 million unless we have obtained the lender's concurrence to borrow in excess of $25.0 million and are in compliance with the terms of the indenture governing our senior notes with respect to the incurrence of additional indebtedness. Borrowings under the revolver accrue interest, at our option, at either (i) the prime rate announced by Citibank, N.A. in New York, plus a margin of 0.0% to 1.0%, or (ii) the London Interbank Offered Rate, plus a margin of 1.75% to 3.00%. We are also required to pay a commitment fee on available but unused amounts ranging from 0.250% to 0.375%. The interest rate margin and commitment fee are based on our leverage ratio, as defined in the agreement governing the revolver. We can use the amounts we draw under the revolver for working capital purposes, acquisitions and vessel construction. On February 25, 2002, the revolver was collateralized by four of our OSVs and four of our ocean-going tugs with an aggregate orderly liquidation value of approximately $75.0 million. We have guaranteed the obligations of Hornbeck Offshore Services, LLC and Hornbeck Offshore Transportation, LLC under the revolver. To date, we have made no borrowings under the revolver. On July 24, 2001, we issued $175.0 million in principal of 10 5/8% Series A senior notes due 2008. We realized net proceeds of $165.0 million, a substantial portion of which was used to repay and extinguish our outstanding indebtedness under our then existing credit facilities, which were terminated. On January 18, 2002, all of the Series A senior notes were exchanged for a like principal amount of our 10 5/8% Series B senior notes due 2008, which are identical in all material respects to the form and terms of the Series A senior notes, except that the offering of the Series B senior notes was registered under the Securities Act of 1933. We did not receive any proceeds from the exchange offer. At March 31, 2002, we had outstanding debt of $172.1 million, net of original issue discount, under the 10 5/8% senior notes. Interest on the 10 5/8% senior notes is payable semi-annually on February 1 and August 1. The 10 5/8% senior notes do not require any payments of principal prior to their stated maturity on August 1, 2008. We are required to make offers to purchase the 10 5/8% senior notes upon the occurrence of certain events, such as asset sales where the proceeds are not reinvested timely or a change in control. The 10 5/8% senior notes are general unsecured obligations and rank equally in right of payment with all our existing and future unsecured senior indebtedness and senior to all our future subordinated indebtedness. Our payment obligations under the 10 5/8% senior notes are fully and unconditionally guaranteed on a senior unsecured basis by all our present and future significant subsidiaries on a joint and several basis. 28

The agreement governing the revolver and the indenture under which the 10 5/8% senior notes were issued impose operating and financial restrictions on us. Such restrictions affect, and in many cases limit or prohibit, among other things, our ability to incur additional indebtedness, make capital expenditures, redeem equity, create liens, sell assets and make dividends or other payments. During 2001, we expended approximately $88.3 million for vessel construction, the Spentonbush/Red Star Group acquisition (including drydocking expenses incurred with respect to such vessels during 2001) and the acquisition of the Energy Service 9001, formerly known as the M/V W.K. McWilliams, Jr. During the three months ended March 31, 2002, we expended approximately $9.9 million for new vessel construction. As of March 31, 2002, we had cash of approximately $42.5 million and working capital of approximately $45.0 million. As of March 31, 2002, we were committed under vessel construction contracts to complete construction of three OSVs. The amount expected to be expended to complete construction of these vessels was approximately $17.3 million as of March 31, 2002, which becomes due at various dates through 2002. In addition, we expect to expend approximately $8.0 million during 2002 for drydocking expenses related to recertification of vessels and other maintenance capital expenditures. During the three months ended March 31, 2002, we expended approximately $0.9 million for drydocking-related expenses for vessels, of which $0.4 million was accounted for as deferred charges and $0.5 million was accounted for as an addition to property, plant and equipment relating to costs incurred for the recertification of acquired vessels that are drydocked within the first 12 months immediately following the acquisition of such vessels. Under our accounting policy, we generally capitalize drydocking expenditures related to vessel recertification to deferred charges and amortize the amount over 30 or 60 months, while routine repairs and maintenance are expensed as incurred. Major replacements and improvements which extend the useful life or functional operating capability are capitalized and depreciated over the vessels remaining economic useful life. During the three months ended March 31, 2002, we also expended approximately $0.4 million for miscellaneous other additions to property, plant and equipment. On May 1, 2002, one of our subsidiaries, Hornbeck Offshore Services, LLC, signed a definitive agreement with LEEVAC Industries, LLC for the construction of the first four vessels of our recently announced newbuild program discussed in the section entitled "Prospectus Summary -- Hornbeck Offshore Services, Inc. -- Recent Developments." Our current and past contracts with LEEVAC Industries were entered into following a competitive bidding process. In connection with our contract with LEEVAC Industries relating to the construction of the first four vessels under our current newbuild program, we received a favorable fairness opinion from an independent appraiser with respect to the terms of the transaction. Aggregate costs for the construction of those vessels, before allocation of construction period interest, are expected to be approximately $53.0 million, which becomes due at various dates through 2003. We plan to fund these costs with a portion of the proceeds we receive from this offering. We believe that cash on hand, cash generated from operations and the proceeds of this offering will provide sufficient funds for the construction of additional OSVs under our newbuild program discussed above and to satisfy debt service and working capital requirements. Any excess funds will be available to finance our strategy, which includes expanding our fleet through the construction or acquisition of additional, or the retrofit of existing OSVs, tugs and tank barges as needed to take advantage of the strong demand for such vessels. Depending on the market demand for OSVs, tugs and tank barges and consolidation opportunities that may arise, we may require additional debt or equity financing. As of December 31, 2001, we had federal net operating loss carryforwards of approximately $8.8 million available through 2017 to offset future taxable income. In addition, we expect our federal tax net operating losses to increase due to our use of accelerated tax depreciation with respect to new vessels. Our use of these net operating losses may be limited due to U.S. tax laws. Based on the age and composition of our current fleet, however, we expect to pay a lower 29

than normal amount of federal income taxes over the next five years. See Note 8 to our Consolidated Financial Statements included in this prospectus. CONTRACTUAL OBLIGATIONS AND COMMERCIAL COMMITMENTS The following table sets forth an aggregation of our contractual obligations and commercial commitments as of March 31, 2002, in thousands of dollars.

- --------------- (1) Net of original issue discount of $2,890. (2) In April 2002, our board of directors approved a newbuild program for the construction of eight additional deepwater OSVs. On May 1, 2002, we signed a definitive agreement with a shipyard for the construction of the first four vessels of this program, each of which will be a 240ED Class vessel. We presently anticipate delivery of all four vessels between June and December 2003. Aggregate construction costs for the four vessels, before allocation of construction period interest, are expected to be approximately $53.0 million. We plan to fund these costs with a portion of the proceeds from this offering. We are currently seeking construction bids from shipyards for the last four vessels of this program. The cost of those last four vessels is not included in the table above. See Note 10 to our consolidated financial statements for further discussion of these commitments. INFLATION To date, general inflationary trends have not had a material effect on our operating revenues or expenses. RECENT ACCOUNTING PRONOUNCEMENTS In early 1998, the American Institute of Certified Public Accountants issued Statement of Position 98-5, "Reporting on the Costs of Start-Up Activities." It is effective for fiscal years beginning after December 15, 1998 and requires costs of start-up activities and organization costs to be expensed as incurred. The unamortized costs of this nature were written off and reflected as a cumulative effect of a change in accounting principle during 1999. Effective January 1, 2001, we adopted Statement of Financial Accounting Standards, or SFAS, No. 133, "Accounting for Derivative Instruments and Hedging Activities," which establishes accounting and reporting standards that every derivative instrument be recorded in the balance sheet as either an asset or liability measured at its fair value. The adoption did not have an impact on our financial position as we have not entered into any derivative instruments. In July 2001, the Financial Accounting Standards Board, or FASB, issued SFAS No. 141, "Business Combinations," and SFAS No. 142, "Goodwill and Other Intangible Assets." SFAS 141 eliminates the pooling-of-interests method of accounting for business combinations except for qualifying business combinations that were initiated prior to July 1, 2001. The purchase method of accounting is required to be used for all business combinations initiated 30

after June 30, 2001. SFAS 141 also requires separate recognition of intangible assets that meet certain criteria. Under SFAS 142, goodwill and indefinite-lived intangible assets are no longer amortized but are reviewed for impairment annually, or more frequently if circumstances indicate potential impairment. Separable intangible assets that are not deemed to have an indefinite life will continue to be amortized over their useful lives. For goodwill and indefinite-lived intangible assets acquired prior to July 1, 2001, goodwill continued to be amortized through 2001 at which time amortization ceased and a transitional goodwill impairment test was performed. Any impairment charges resulting from the initial application of the new rules will be classified as a cumulative change in accounting principle. The initial transition evaluation was completed by June 30, 2002, which is within the six month transition period allowed by the new standard. The Company's goodwill balances were determined not to be impaired. Goodwill amortization for each of the years ended December 31, 1999, 2000 and 2001 was $126. In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations," which requires recording the fair value of a liability for an asset retirement obligation in the period incurred. SFAS 143 is effective for fiscal years beginning after June 15, 2002, with earlier application permitted. Upon adoption of SFAS 143, we will be required to use a cumulative effect approach to recognize transition amounts for any existing retirement obligation liabilities, asset retirement costs and accumulated depreciation. We do not have any asset retirement obligations; therefore, adoption of this statement will not have any effect on our financial statements. In August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," which supersedes FASB Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of." SFAS 144 also supersedes certain aspects of APB 30, "Reporting the Results of Operations -- Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions," with regard to reporting the effects of a disposal of a segment of a business and will require expected future operating losses from discontinued operations to be reported in discontinued operations in the period incurred rather than as of the measurement date as presently required by APB 30. The provisions of SFAS 144 are required to be applied for fiscal years beginning after December 15, 2001 and interim periods within those fiscal years. The adoption of this statement is not expected to have any effect on our financial statements. In April 2002, the FASB issued SFAS No. 145, "Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections." SFAS 145 requires that gains or losses recorded from the extinguishment of debt that do not meet the criteria of APB Opinion No. 30 should not be presented as extraordinary items. This statement is effective for fiscal years beginning after May 15, 2002 as it relates to the reissued FASB Statement No. 4, with earlier application permitted. Any gain or loss on extinguishment of debt that was classified as an extraordinary item in prior periods presented that does not meet the criteria in APB 30 for classification as an extraordinary item should be reclassified. The company has elected not to adopt this SFAS early. Accordingly, the losses on extinguishment of debt incurred in 2001 remain classified as an extraordinary item in our accompanying statement of operations. CHANGE IN INDEPENDENT PUBLIC ACCOUNTANTS AND AUDITORS Effective June 24, 2002, we dismissed Arthur Andersen LLP as our independent public accountants and auditors and engaged Ernst & Young LLP as our new independent public accountants and auditors. The decision to change the Company's independent public accountants and auditors was approved by our board of directors upon the recommendation of its audit committee. 31

Arthur Andersen's reports on our consolidated financial statements for the years ended December 31, 2001 and 2000, respectively, did not contain an adverse opinion or disclaimer of opinion, nor were such reports qualified or modified as to uncertainty, audit scope, or accounting principles. In addition, during the two years ended December 31, 2001 and the subsequent interim period preceding the decision to change independent public accountants and auditors, there was no disagreement with Arthur Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement, if not resolved to the satisfaction of Arthur Andersen, would have caused it to make a reference to the subject matter of the disagreement in connection with its reports covering such periods, and there were no other events relating to Arthur Andersen's service as our independent public accountants and auditors that would have required disclosure under applicable Commission regulations. We did not consult Ernst & Young LLP on any financial or accounting reporting matters in the period prior to its appointment. 32

BUSINESS GENERAL We are a leading owner and operator of deepwater-capable offshore supply vessels serving the offshore oil and gas industry. In 1997, we commenced a growth-oriented newbuild program using our proprietary deepwater-OSV designs. We currently operate a fleet of 11 deepwater OSVs in the Gulf of Mexico with an average age of approximately two years. We have 10 additional deepwater OSVs planned or under construction. Upon completion of this offering, we will be the only publicly-traded company with a significant concentration of purpose-built, deepwater OSVs in the Gulf of Mexico. Demand for our OSV services is primarily driven by deepwater drilling and production activity. In the late-1990s, we identified a significant opportunity in and developed a plan to exploit the emerging interest in deepwater exploration and production in the Gulf of Mexico. Since then, the deepwater Gulf of Mexico has become an increasingly active oil and natural gas producing region. According to the Minerals Management Service, in 2001, the deepwater accounted for approximately 59% of total Gulf of Mexico oil production and 23% of total Gulf of Mexico natural gas production. Successful exploration and development in deepwater areas requires a new generation of expensive drilling rigs and production platforms and other advanced drilling and production technology. We believe that these expensive projects are served most effectively by a new generation of deepwater OSVs capable of supporting day-to-day operations in a manner that minimizes costly downtime in terms of both drilling rig dayrates and lost oil and natural gas production. We believe that the existing fleet of conventional, 180' OSVs working in shallow water areas, such as the continental shelf of the Gulf of Mexico, is not capable of operating effectively in the deepwater market due to insufficient cargo capacity and lack of dynamic positioning capability. Dynamic positioning allows a vessel to maintain position without the use of anchors through a sophisticated, computerized system. Since 1997, we have assembled a core team of naval architects and other marine professionals to design and operate a new class of OSVs that specifically address the challenges of deepwater operations. All of our deepwater OSVs have been built based on the proprietary designs and to the specifications of our in-house design team. As a result, all of our deepwater OSVs have enhanced capabilities that allow them to be used effectively in all stages of a deepwater project and for specialty services. Although we currently operate exclusively in the Gulf of Mexico, our OSVs are capable of operating in all deepwater regions around the world. We are also a leading provider of marine transportation services to the energy industry in the northeastern United States and Puerto Rico. We own and operate a fleet of 13 ocean-going tugs, 16 ocean-going tank barges and one coastwise tanker. We believe our tug and tank barge business complements our OSV business, provides additional revenue and geographic diversification and allows us to offer another line of services to integrated oil and gas companies. Demand for our tug and tank barge services is driven by the consumption of refined petroleum products. OFFSHORE SUPPLY VESSELS THE OSV INDUSTRY Offshore supply vessels serve exploratory and developmental drilling rigs and production facilities and support offshore construction and subsea maintenance activities. OSVs differ from other types of marine vessels in their cargo carrying flexibility and capacity. In addition to transporting deck cargo, such as pipe or drummed material and equipment, OSVs transport liquid mud, potable and drilling water, diesel fuel and dry bulk cement. 33

In general, demand for OSVs is primarily related to the level of drilling activity, which can be influenced by a number of factors, including oil and natural gas prices and drilling budgets of exploration and production companies. As a result, utilization and dayrates are directly related to oil and natural gas prices and drilling activity. However, dayrates and utilization in deepwater regions are less sensitive to short-term commodity price fluctuations due to the long-term nature of deepwater projects. The Gulf of Mexico is a critical oil and natural gas supply basin for the United States, accounting for 20% and 26%, respectively, of total U.S. oil and natural gas production in 2001. Offshore oil and natural gas activity in the Gulf of Mexico is bifurcated between the shallow water, or continental shelf, and deepwater regions. Each region has distinct characteristics both in terms of oil and natural gas exploration, development and production activities and OSV requirements. The continental shelf of the Gulf of Mexico is a mature producing region with hydrocarbon reserves that demonstrate increasingly rapid production decline rates. While significant infrastructure exists in this region and oil and natural gas exploration, development and production activities are less costly than in the deepwater, drilling activity is more sensitive to fluctuations in commodity prices, particularly the price of natural gas. Decreases in oil and natural gas prices generally result in reduced offshore drilling activity and lower demand for OSV services in the shallow water areas of the Gulf of Mexico as low commodity prices undermine the economic viability of these projects. This causes a corresponding decline in dayrates for and utilization of OSVs that operate in this region. By contrast, the deepwater region of the Gulf of Mexico, which is generally defined as water depths between 1,000 and 5,000 feet, is an emerging market with many unexplored areas of potential oil and natural gas reserves and is an increasingly important source of oil and natural gas production. From 1990 to 2001, production in the deepwater Gulf of Mexico increased from 4% to 59% of total Gulf of Mexico oil production and from 1% to 23% of total Gulf of Mexico natural gas production. The relatively large capital commitments, long lead times and investment horizons associated with deepwater exploration, development and production activities make it less likely that an oil and gas company will abandon a deepwater project upon a short-term decline in oil or natural gas prices. This is particularly true in the ultra-deepwater, which is generally defined as water depths in excess of 5,000 feet. As a result, despite recent fluctuations in commodity prices, the active Gulf of Mexico OSV fleet operating in the deepwater and ultra-deepwater regions continues to operate at nearly 100% utilization at dayrates that have remained stable. According to Offshore Marine Services Association, the U.S.-flagged OSV fleet totaled 338 vessels as of May 1, 2002, substantially all of which were located in the Gulf of Mexico. Of this total, approximately 248, or 73% are conventional, 180' OSVs that were operating primarily on the continental shelf. Approximately 90 are deepwater capable and were operating primarily in the deepwater Gulf of Mexico. Of the conventional OSV fleet, 95 were cold-stacked. Vessels that are cold stacked have generally been removed from active service by the operator due to lack of demand. In contrast, no deepwater OSVs were cold-stacked at that time. THE MARKET FOR DEEPWATER OSVS Deepwater drilling, exploration and production activities require specialized equipment and higher volumes of supplies to meet the more difficult operating environment that characterizes the deepwater region. To accommodate operations in this environment and meet customer demands, deepwater OSVs, including our entire OSV fleet, are designed with larger capacities, including greater liquid mud and dry bulk cement capacities, as well as larger areas of open deck space, and longer ranges than conventional OSVs. In addition, drilling rigs and OSVs operating in deepwater environments generally require dynamic positioning, or anchorless station-keeping, 34

capability to enable continued operation in adverse weather conditions. For safety reasons, customers do not allow OSVs to tie up to deepwater installations. We believe that vessels in the existing fleet of conventional OSVs, substantially all of which lack dynamic positioning capability and sufficient on-deck or below-deck cargo capacity, are not capable of operating effectively or economically in the deepwater market. Recent deepwater discoveries of deepwater fields in the Gulf of Mexico have resulted in increased developmental and exploratory drilling activities. Of the 86 deepwater Gulf of Mexico fields discovered to date, 56 fields had begun production by the end of June 2002. Moreover, utilization rates for deepwater OSVs in the Gulf of Mexico have averaged nearly 100% over the last two years compared to an average utilization rate for the conventional OSV fleet of approximately 75% over the same period. Given the recent and expected deepwater activity, we believe that the supply of OSVs, including vessels currently available and vessels being constructed under announced construction plans, is insufficient to meet demand for such vessels. Furthermore, although U.S.-flagged vessels operating in overseas locations may be remobilized to the Gulf of Mexico, we believe it is unlikely that any such remobilization would have a significant impact on the supply of deepwater OSVs in the near future. With the existing deepwater fleet operating near full capacity, this demand is most likely to be met through new construction of deepwater OSVs. OUR OSV BUSINESS We currently own and operate a fleet of 11 deepwater OSVs, have 10 deepwater OSVs planned or under construction. Our in-house engineering team designed our fleet of OSVs specifically to meet the demands of deepwater regions. Where appropriate, we work closely with potential charterers to design vessels specifically to meet their anticipated needs, particularly when the charterer will operate a deepwater project that could have a duration of more than 20 years and require expenditures exceeding $1 billion. Our vessels have two to three times the dry bulk capacity and deck space, three to 10 times the liquid mud capacity and two to four times the deck tonnage compared to conventional, 180' OSVs, which are used primarily on the continental shelf. Our advanced cargo handling systems allow for dry bulk and liquid cargoes to be loaded and unloaded three times faster, while the solid state controls of our engines typically result in a 20% greater fuel efficiency than vessels powered by conventional engines. In addition, we believe that the superior capabilities of our deepwater OSVs allow them to earn higher average dayrates and utilization rates than those generated by our peers. All of our OSVs are equipped with advanced dynamic positioning systems which allow our vessels to maintain position within a minimal variance. The unique hull design and integrated rudder and thruster system of our OSVs provide for a more manageable vessel. Our OSVs have been designed with state-of-the-art lifesaving monitoring, emergency power, fire-alarm and fire suppression systems and systems monitoring equipment. These vessels also have double-bottomed and double-sided hulls that minimize the environmental impact of hull penetrations, solid state control that minimizes visible soot and polluting gases and zero discharge sewage and waste systems that minimize the impact on marine environments. Although we currently operate exclusively in the Gulf of Mexico, our vessels are capable of operating in deepwater regions around the world and all of our vessels are either fully SOLAS (Safety of Life at Sea) certified or SOLAS ready. SOLAS is the international convention that regulates the technical characteristics of vessels for purposes of ensuring international standards of safety for vessels engaged in commerce between international ports. We designed our OSVs to support certain specialty services, including well stimulation, remotely operated vehicles, or ROVs, used in oilfield subsea construction and maintenance, underwater inspections, marine seismic operations, and certain non-energy applications such as fiber optics cable installation. We design our OSVs to include such characteristics as maneuverability, fuel efficiency and firefighting capacity, which strengthens demand for their use 35

in specialty situations. Two of our vessels, the HOS Innovator and the HOS Dominator, currently provide ROV subsea construction and maintenance support under three-year contracts with a large oilfield service company. The BJ Blue Ray operates under a five-year contract to support well stimulation services for another large oilfield service company. The following table provides information, as of July 1, 2002, regarding our existing fleet of deepwater OSVs, as well as those we currently have under construction. OFFSHORE SUPPLY VESSELS

TUGS AND TANK BARGES THE TUG AND TANK BARGE INDUSTRY Petroleum products are transported in the northeastern United States through a vast network of refineries, terminals, tankers and pipelines. We believe, based upon our analysis of the industry, that approximately 1.2 million barrels of petroleum products are transported each day by tank barges operating in the coastwise trade in this region. Tugs and tank barges are also used to transport petroleum products in Puerto Rico and other Caribbean islands. Demand for tug and tank barge services in the northeastern United States is primarily driven by population growth, the strength of the U.S. economy and changes in weather and transportation patterns that affect consumption of heating oil, gasoline, diesel and jet fuel. The tank barge market in general is marked by steady demand and we believe that demand for refined petroleum products and crude oil will remain steady in the foreseeable future. The largest single market in the northeastern United States is New York Harbor. Imported petroleum products are primarily delivered to New York Harbor as it has the capacity to receive products in cargo lots of 50,000 tons or more per tanker. By contrast, draft limitations in most New England ports and drawbridge limitations in Boston and Portland, Maine limit the average cargo carrying capacity of direct imports into many of the largest New England ports to about 30,000 tons per tanker. As a result, ships importing directly into New England must frequently discharge in multiple ports or terminals or transfer cargoes to tank barges, involving more time and cost. As existing tankers are retired, they are typically replaced by larger tankers. As larger petroleum tankers are being built, we believe that direct delivery into New York Harbor with onward barging to New England, the Hudson River and Long Island will increase. We also believe that demand for barging services will increase as larger oil tankers are built to replace oil tankers removed from service due to mandates under the Oil Pollution Act of 1990, or OPA 90. These larger-sized tankers are being built to facilitate the importation of crude oil and petroleum products into the United States, which is expected to grow at compound annual growth rates of 1.7% and 4.9%, respectively, through 2020, according to the Energy Information Agency. These larger tankers will require lightering services provided by tugs and tank barges. In addition, OPA 90 has imposed significant limits on the service lives and capacity of most existing tank barges. Based upon our analysis of the industry, we believe that at the time OPA 90 was passed, approximately 50% of the U.S. flagged tanker and tank barge fleet in the northeastern United States affected by OPA 90 was required to be retired or substantially reconstructed by December 31, 2004. Based on the remaining lives of the majority of our tank barge fleet under OPA 90, we believe we are well positioned to obtain additional customers in the northeastern United States as currently available capacity is required to be removed from service or substantially reconstructed. OUR TUG AND TANK BARGE BUSINESS We own and operate a fleet of 13 ocean-going tugs, 16 ocean-going tank barges, one of which has been bareboat chartered to a third party, and one coastwise tanker. Generally, a tug and tank barge work together as a "tow" to transport refined or bunker grade petroleum products. Our tank barges carry petroleum products that are typically characterized as either "clean" or "dirty" along the upper east coast of the United States, the coast of Puerto Rico and in the Caribbean. Clean products are primarily gasoline, home heating oil, diesel fuel and jet fuel. Dirty products are mainly crude oils, residual crudes and feedstocks, heavy fuel oils and asphalts. Our tugs and tank barges serve the northeastern U.S. coast, primarily New York Harbor, by transporting both clean and dirty petroleum products to and from refineries and distribution terminals. Our tugs and tank barges also transport both clean and dirty petroleum products from 38

refineries and distribution terminals to the Puerto Rico Electric Power Authority and to utilities located on other Caribbean islands. In addition, we provide ship lightering, bunkering and docking services in these markets and are well positioned to provide such services to the new tankers that are too large to make direct deliveries to distribution terminals and refineries. On May 31, 2001, we acquired nine ocean-going tugs and nine ocean-going tank barges from the Spentonbush/Red Star Group, composed of certain affiliates of Amerada Hess, as well as the business related to these tugs and tank barges, greatly expanding our capacity in the northeastern United States and increasing our market share of the coastwise trade on the U.S. upper east coast. As part of the acquisition, Amerada Hess entered into a long-term contract of affreightment with us pursuant to which Amerada Hess has committed to use us as its exclusive marine logistics provider and transporter of liquid petroleum products in the northeastern United States. Under this contract, Amerada Hess has committed to ship a minimum of 45 million barrels annually for an initial period from June 1, 2001 through March 31, 2006 with options to renew for subsequent periods. Also under the contract, we have the opportunity, on a reasonable commercial efforts basis, to coordinate the marine logistics for Amerada Hess in the southeastern United States, subject to Amerada Hess's right to cancel within 30 days after December 31 of each year of the contract. The contract of affreightment will provide us with a significant source of revenues over the life of the contract. Our contract of affreightment allows Amerada Hess to reduce its minimum annual cargo volume commitment subject to a significant adjustment penalty. If Amerada Hess does not transport volumes as contemplated under the contract, we believe that we would be able to replace such volumes through other customers. The following tables provide information, as of July 1, 2002, regarding the tugs, tank barges and the coastwise tanker we own. OCEAN-GOING TUGS

- --------------- (1) For a discussion of OPA 90 see "-- Environmental and Other Governmental Regulations" below. (2) This coastwise tanker, formerly known as the M/V W.K. McWilliams, Jr., was acquired on November 15, 2001 and is not currently certificated to transport petroleum products. Therefore, barrel capacity is not applicable to this vessel. COMPETITIVE STRENGTHS Technologically Advanced Fleet of Deepwater OSVs. Our OSVs were designed with the operating specifications necessary for operations in deepwater regions and have significantly more capacity and operate more efficiently than conventional OSVs. In addition, we believe that safety is an increasingly important consideration for oil and gas operators due to the environmental and regulatory sensitivity associated with offshore drilling and production activity. While operators are especially concerned with a vessel's ability to avoid collisions with multi-million dollar drilling rigs or production platforms during adverse weather conditions, they are hesitant to stop operations in such conditions because of the high daily cost of halting a deepwater operation. Our vessels incorporate sophisticated technologies and are designed specifically to operate safely in the rougher seas in the deepwater Gulf of Mexico. These technologies include dynamic positioning, roll reduction, controllable pitch thrusters and our unique cargo handling systems, which permit high volume transfer rates of liquid mud and dry bulk. We believe that we earn higher average dayrates and utilization rates than those of our peers for the following reasons: the superior capabilities of our deepwater OSVs and the collaborative efforts of our in-house design team in providing marine engineering solutions to our customers. Young OSV Fleet. We believe that we operate the youngest fleet of OSVs in the Gulf of Mexico. While over 70% of the Gulf of Mexico OSV fleet is over 18 years old, the average age of 40

our OSV fleet is approximately two years, and we have 10 additional deepwater OSVs currently planned or under construction. Newer vessels experience less downtime and require significantly less capital expenditures for scheduled drydockings and maintenance compared to older vessels. The average drydocking for recertification for one of our OSVs generally lasts five to 10 days in the shipyard and costs approximately $0.2 million. In contrast, the typical drydocking for recertification of a conventional, 180-foot OSVs may last 60 to 90 days in the shipyard and can cost as much as $1.5 million. We believe that our operation of new technologically advanced, deepwater OSVs gives us a competitive advantage in obtaining long-term contracts for our vessels and in attracting and retaining crews. Since we accepted delivery of our first OSV in November 1998, the average utilization rate for our OSVs has been approximately 95%. According to One Offshore, formerly Offshore Data Services, the Gulf of Mexico industry average was approximately 75% over the same time period, based on vessels available for service. We expect that our newer, larger, faster and more cost-efficient vessels will remain in high demand as deepwater exploration, development and production activity continues to increase globally. Leading Market Presence in Core Target Markets. We are the second largest operator of deepwater OSVs in the Gulf of Mexico. We have a larger presence in the deepwater Gulf of Mexico than any of our publicly traded competitors, with 11 OSVs. We will strengthen this position and our ability to serve other markets following delivery of the 10 deepwater OSVs we currently have planned or under construction. We operate the largest fleet of tugs and tank barges for the transportation of petroleum products in Puerto Rico and believe that we are also the fourth largest tank barge transporter of petroleum products in New York Harbor. Our offshore supply vessel and ocean-going tug and tank barge fleets also benefit from the restrictions of Section 27 of the Merchant Marine Act of 1920, commonly referred to as the Jones Act, which requires that vessels engaged in coastwise U.S. trade, including along the coast of Puerto Rico, be built in the United States, be U.S.-flagged and be owned and managed by U.S. citizens. This law effectively prohibits vessels that are either foreign-flagged or foreign-built, whether owned and operated by foreign or domestic companies, from operating in our market areas. Successful Track Record of Deepwater OSV Construction. Our management possesses significant naval architecture, marine engineering and shipyard experience. We believe we are unique in the manner in which we design our own OSVs and work closely with our contracted shipyards in their construction. In addition, we typically source and supply much of the owner-furnished equipment from vendors other than the shipyard, comprising a large portion of the aggregate cost of a vessel. This approach results in substantial cost savings by avoiding the shipyard's mark-up on such equipment and enabling us to qualify for volume discounts with our non-shipyard vendors. This approach also fosters direct relationships with the vendors of our major equipment systems, which enhances the level of service we receive from such vendors during the warranty period. We delivered our current fleet of 11 deepwater OSVs substantially on time and on budget. We believe that our history of delivering new vessels without significant delays provides us with a competitive advantage in obtaining contracts for our vessels prior to their actual delivery. The shipyard responsible for two of our OSVs currently under construction has notified us that delivery of these vessels will be delayed from their original delivery dates. We do not believe that such delays in the delivery of these vessels will have a material adverse effect on our financial condition and results of operations or ability to charter these OSVs prior to their delivery. Favorable OPA 90 Fleet Status. Based upon our analysis of the industry, we believe that at the time OPA 90 was passed, approximately 50% of the single hulled tank barge capacity serving the northeastern United States was required to be retired or substantially reconstructed before 2005. Eleven of our 16 tank barges are not required under OPA 90 to be retired or double hulled until 2015. Of the remainder, three are required to be retired or modified before 2005, and two in 2009. Our coastwise tanker, the Energy Service 9001, is not subject to OPA 90 retirement dates. Because most of our barges are not required to be double hulled until 2015, we believe we have 41

a competitive advantage over operators with significant numbers of tank barges that must be retired or modified to add double hulls before that date. Long-Term Contracts and a Diversified Fleet. Currently, six of our 11 OSVs operate under long term contracts with expiration dates ranging from April 2003 to November 2006. These contracts generally provide for full year-round utilization, are based on dayrates with a built-in escalation clause and are exclusively dedicated to the charterer. We often receive more inquiries regarding the charter of our vessels than we have vessels to contract, allowing us to select our charterers carefully. We continue to experience high levels of inquiries as potential charterers have become aware of the capabilities and performance of our newly constructed OSVs. A majority of our tug and tank barge capacity is operating under a long-term contract of affreightment through at least November 2006. In addition, our long term contract with Amerada Hess, when coupled with our operation of tugs and tank barges in both the northeastern United States and Puerto Rico, provides revenue diversification to complement our OSV fleet. We also operate four of our tank barges in the Caribbean under contracts that have been renewed in each of the last three years. We believe that by having many of our vessels operating under long-term contracts, we have a competitive advantage because it provides us a stable base of revenue and cash flow throughout the energy service industry cycle, and enhances our ability to manage our long-term growth. Experienced Management Team with Proven Track Record. Our senior management team has an average of 21 years of domestic and international marine transportation industry-related experience. We believe that our team has successfully demonstrated its ability to grow our fleet through new construction and strategic acquisitions and to secure profitable contracts for our vessels in favorable and unfavorable market conditions. Moreover, our in-house engineering team enables us to design and manage our new vessel construction program, adapt our vessels for specialized purposes, oversee and manage the drydocking process and provide custom marine engineering solutions to our customers. We believe this will continue to result in a lower overall cost of ownership over the life of our vessels compared to our competitors, as well as a competitive advantage in securing contracts for our OSVs as the benefits of our proprietary designs and in-house engineering capabilities are recognized by our customers. Numerous Industry-Recognized Safety and Quality Certifications. As part of our commitment to quality and safety, we have pursued on a voluntary basis and have received certifications and classifications that are not generally held by other companies in our industry. We maintain ISO 9000 and ISO 14001 certifications for quality and environmental management, respectively, from the International Standards Organization with respect to the nine tugs and nine tank barges acquired from the Spentonbush/Red Star Group. Our other tugs and tank barges participate in the Responsible Carrier Program, developed by the American Waterways Operators to improve marine safety and environmental protection in the tank barge industry. We are the only OSV company operating in the Gulf of Mexico that is approved under the U.S. Coast Guard's Streamlined Inspection Program in which we and the Coast Guard cooperate to develop training, inspection and compliance processes, with our personnel conducting periodic examinations of vessel systems and taking corrective actions where necessary. Both of our principal office locations in Mandeville, Louisiana and Brooklyn, New York, as well as the majority of our vessels, including all of our OSVs and our tugs and tank barges acquired from the Spentonbush/ Red Star Group, are also certified under the International Safety Management Code, developed by the International Maritime Organization to provide internationally recognized standards for the safe management and operation of ships and for pollution prevention. Our OSVs are classed by the American Bureau of Shipping, which develops and verifies standards for the design, construction and operational maintenance of vessels and facilities. We believe that our numerous industry certifications are a competitive advantage given that safety is an increasingly important consideration for oil and gas operators due to the environmental and regulatory sensitivity associated with offshore drilling and production activity. 42

OUR STRATEGY We recently adopted the following mission statement, which we believe summarizes our strategy: "Our mission is to be recognized as the energy industry's marine transportation and service company of choice for our customers, employees and investors through innovative, high quality, value-added business solutions delivered with enthusiasm, integrity and professionalism with the utmost regard for the safety of individuals and the protection of the environment." To implement our mission, we have developed a strategy including the following elements: Maintain Technologically Advanced Fleet. We designed our OSVs to meet the higher capacity and performance needs of our clients' drilling and production programs. We have accomplished this by building our deepwater OSVs with sophisticated propulsion and cargo handling systems, dynamic positioning capabilities and larger capacities. We are committed to applying existing or developing new technologies in each new vessel construction program in order to continue to improve our service offerings and meet the evolving needs of our customers. Maintain Strong Focus In Deepwater Regions. We intend to maintain our focus on operating high quality OSVs in deepwater regions. Oil and natural gas exploration and development activity in this region have increased recently as a result of several factors including world-class exploration potential, improvements in exploration and production technologies for deepwater projects, and slowing or declining production from onshore and shallow water fields. We believe that the deepwater regions worldwide will continue to be active areas for exploration and development in the foreseeable future, and that demand for our OSVs, which are uniquely equipped to serve the current and planned drilling programs in these markets, will continue to be strong. Expand Fleet Through Newbuilds And Selective Acquisitions. We plan to expand our fleet through construction of new vessels, including our recently announced eight-vessel newbuild program and strategic acquisitions. Market demand for vessels, including demand in international markets, will be the main determinant of the level and timing of construction of additional vessels. We believe that acquisition opportunities are likely to arise as consolidation in our industry continues. We intend to use our expertise and experience to evaluate strategic acquisitions where the opportunity exists to increase market share and create or enhance long-term client relationships. To date, we have completed four acquisitions involving ocean-going tugs and tank barges. Pursue Optimal Mix of Long-Term and Short-Term Contracts. We seek to balance our portfolio of charters with both long-term and short-term charters. Long-term contracts provide more predictable cash flow, and short-term charters may provide the opportunity to benefit from increasing dayrates. We intend to maintain a significant percentage of our assets working under long-term contracts, which results in high utilization rates and provides a stable cash flow base to manage debt obligations. The average initial term for our current OSV term contracts is approximately three years. Our contract of affreightment with Amerada Hess for the services of tugs and tank barges in the northeastern United States has an initial term of June 1, 2001 through March 31, 2006. All of our other tug and tank barge contracts typically have been renewed annually over the last several years. Continue To Leverage Existing Customer Relationships. We intend to build upon existing customer relationships by expanding our services to those customers with diversified marine transportation needs. Many integrated oil and gas companies require OSVs to support their exploration and production activities and ocean-going tugs and tank barges to support their refining, trading and retail distribution activities. In addition, many of our customers conduct operations in international markets and have expressed interest in chartering our OSVs for use overseas. Our OSVs are capable of operating in all of the major deepwater oil and natural gas producing regions of the world. Our management team has significant international experience and is currently evaluating several such opportunities. 43

Optimize Tug And Tank Barge Operations. Prior to our acquisition of tugs and tank barges from the Spentonbush/Red Star Group, those vessels were largely dedicated to the use of Amerada Hess and its affiliates in New York Harbor. Since that acquisition, we have consolidated the operational management of our entire tug and tank barge fleet, including our Puerto Rican fleet, in our Brooklyn facility. This will enable us to market our services to customers other than Amerada Hess in the northeastern United States, while we continue our efforts to reduce costs and otherwise optimize utilization. CUSTOMERS AND CHARTER TERMS Major oil companies, large independent oil and gas exploration, development and production companies and large oil service companies constitute the majority of our customers for our OSV services, while refining, marketing and trading companies constitute the majority of our customers for our tug and tank barge services. The percentage of revenues attributable to a customer in any particular year depends on the level of oil and natural gas exploration, development and production activities undertaken or refined petroleum products or crude oil transported by a particular customer, the availability and suitability of our vessels for the customer's projects or products and other factors, many of which are beyond our control. For the year ended December 31, 2001, Amerada Hess Corporation and Mariner Energy, Inc. each accounted for more than 10% of our total revenues for such period. We enter into a variety of contract arrangements with our customers, including spot and time charters, contracts of affreightment and consecutive voyage contracts. Our contracts are obtained through competitive bidding or, with established customers, through negotiation. Currently, six of our 11 OSVs operate under long-term charters, with initial terms of one year or longer and expiration dates ranging from April 2003 through November 2006. Most of the contracts for our OSVs contain early termination options in favor of the customer; however some have substantial early termination penalties designed to discourage the customers from exercising such options. Similarly, 13 of our 16 tank barges provide services under long-term contracts with initial terms of one year or longer. Our OSVs have performed services for approximately 34 different customers, and our tugs and tank barges have performed services for approximately 84 different customers. Because of the variety and number of customers historically using the services of our fleet, and the near equal balance between supply and demand in both the OSV and tug and tank barge markets, we believe that the loss of any one customer would not have a material adverse effect on our business. Because we have established a reputation for on time delivery and reliability, charterers have contacted us to construct vessels to meet their needs. In such circumstances, we generally contract these specially designed vessels for three to five years, with renewal options, before construction is completed. Although we will design vessels to meet the specific needs of a charterer, we ensure in our design that customization does not preclude efficient operation of these vessels for other customers, for other purposes or in other situations. Two of our OSVs had been under long-term charter to Mariner Energy, Inc., which is 96%-owned by an indirect affiliate of Enron Corp. Mariner had been using these two vessels to service an offshore drilling rig it has chartered for drilling operations in the Gulf of Mexico. On December 11, 2001, Mariner notified us of its intent to furlough the drilling rig by December 15, 2001 and unilaterally sought to terminate its contract with respect to our two vessels. Mariner released one of our vessels on December 14, 2001 and the other on December 16, 2001. We do not believe that Mariner's actions will have a material adverse affect on our financial condition or results of operations. Both vessels have been redeployed under spot market charters with other customers earning substantially the same dayrates as under the Mariner contract with almost no lapse in utilization. We continue to experience strong demand for OSVs capable of operating in the deepwater Gulf of Mexico based on the ongoing requests we receive 44

from other customers for the services of our vessels. In addition, we are in discussions with several customers regarding term contract opportunities for these vessels. Furthermore, we are also in discussions with Mariner to re-establish our working relationship. All accounts receivable from Mariner for base charter hire prior to the release of our vessels have been fully paid. COMPETITION We operate in a highly competitive industry. Competition in the deepwater OSV and ocean-going tug and tank barge segments of the marine transportation industry primarily involves factors such as: - capability of the vessels; - ability to meet the customer's schedule; - safety record; - reputation; - price; and - experience. Under the terms of the Jones Act, competition in the coastwise trade in the United States and Puerto Rico is limited to vessels built in the United States that are U.S.-flagged and owned and managed by U.S. citizens. We do not anticipate significant competition in the near term from pipelines as an alternative method of petroleum product delivery in the northeastern United States or Puerto Rico. No pipelines are currently under construction that could provide significant competition to tank barges in the northeastern United States or Puerto Rico, nor are any new pipelines likely to be built in the near future due to cost constraints and logistical and environmental requirements. We believe that prior to this offering, approximately 75% of the OSVs operating in the deepwater Gulf of Mexico are owned by privately-held companies. We believe we operate the second largest fleet of deepwater OSVs in the Gulf of Mexico, and, after this offering we will be the only publicly-traded company with a significant concentration of purpose-built, deepwater OSVs in the Gulf of Mexico. In contrast, approximately 82% of the OSVs operating on the continental shelf of the Gulf of Mexico are owned by publicly-traded companies. We operate the largest tank barge fleet in Puerto Rico and we believe that we are the fourth largest transporter by tank barge of petroleum products in New York Harbor. Virtually all of our competitors in the tug and tank barge industry are privately held. Although some of our principal competitors are larger and have greater financial resources and current international operations, we believe that our operating capabilities and reputation enable us to compete effectively with other fleets in the market areas in which we operate. In particular, we believe that the relatively young age and advanced features of our OSVs provide us with a competitive advantage in both the continental shelf and deepwater segments of the Gulf of Mexico. The ages of our OSVs range from one month to 41 months, while approximately 70% of the OSVs operating in the continental shelf area of the Gulf of Mexico are over 18 years old, with many approaching 25 years old. We believe that many of these older vessels will be retired in the next few years. In addition to the young age of our fleet, the advanced capabilities of our fleet position us to take advantage of the expanding deepwater segment of the Gulf of Mexico. 45

ENVIRONMENTAL AND OTHER GOVERNMENTAL REGULATION Our operations are significantly affected by a variety of federal, state and local laws and regulations governing worker health and safety and the manning, construction and operation of vessels. Certain governmental agencies, including the U.S. Coast Guard, the National Transportation Safety Board, the U.S. Customs Service and the Maritime Administration of the U.S. Department of Transportation, have jurisdiction over our operations. In addition, private industry organizations such as the American Bureau of Shipping oversee aspects of our business. The Coast Guard and the National Transportation Safety Board establish safety criteria and are authorized to investigate vessel accidents and recommend improved safety standards. The U.S. Coast Guard regulates and enforces various aspects of marine offshore vessel operations. Among these are classification, certification, routes, drydocking intervals, manning requirements, tonnage requirements and restrictions, hull and shafting requirements and vessel documentation. Coast Guard regulations require that each of our vessels be drydocked for inspection at least twice within a five-year period. Under Section 27 of the Merchant Marine Act of 1920, also known as the Jones Act, the privilege of transporting merchandise or passengers for hire in the coastwise trade in U.S. domestic waters extends only to vessels that are owned and managed by U.S. citizens and are built in and registered under the laws of the United States. A corporation is not considered a U.S. citizen unless, among other things: - the corporation is organized under the laws of the United States or of a state, territory or possession of the United States; - at least 75% of the ownership of voting interest with respect to its capital stock is held by U.S. citizens; - the corporation's chief executive officer, president and chairman of the board are U.S. citizens; and - no more than a minority of the number of directors necessary to constitute a quorum for the transaction of business are foreigners. We meet all of the foregoing requirements. If we fail to comply with these requirements, our vessels lose their eligibility to engage in coastwise trade within U.S. domestic waters. To facilitate compliance, our certificate of incorporation: - limits ownership by foreigners of any class of our capital stock (including our common stock) to 20%, so that foreign ownership will not exceed the 25% permitted; - permits withholding of dividends and suspension of voting rights with respect to any shares held by foreigners that exceed 20%; - permits a stock certification system with two types of certificates to aid tracking of ownership; - permits our board of directors to redeem any shares held by foreigners that exceed 20%; and - permits our board of directors to make such determinations to ascertain ownership and implement such measures as reasonably may be necessary. Our operations are also subject to a variety of federal, state, local and international laws and regulations regarding the discharge of materials into the environment or otherwise relating to environmental protection. The requirements of these laws and regulations have become more complex and stringent in recent years and may, in certain circumstances, impose strict liability, rendering a company liable for environmental damages and remediation costs without regard to negligence or fault on the part of such party. Aside from possible liability for damages and costs 46

including natural resource damages associated with releases of hazardous materials including oil into the environment, such laws and regulations may expose us to liability for the conditions caused by others or even acts of ours that were in compliance with all applicable laws and regulations at the time such acts were performed. Failure to comply with applicable laws and regulations may result in the imposition of administrative, civil and criminal penalties, revocation of permits, issuance of corrective action orders and suspension or termination of our operations. Moreover, it is possible that changes in the environmental laws, regulations or enforcement policies or claims for damages to persons, property, natural resources or the environment could result in substantial costs and liabilities to us. We believe that we are in substantial compliance with currently applicable environmental laws and regulations. OPA 90 and regulations promulgated pursuant thereto impose a variety of regulations on "responsible parties" related to the prevention of oil spills and liability for damages resulting from such spills. A "responsible party" includes the owner or operator of an onshore facility, pipeline or vessel or the lessee or permittee of the area in which an offshore facility is located. OPA 90 assigns liability to each responsible party for oil removal costs and a variety of public and private damages. Under OPA 90, "tank vessels" of over 3,000 gross tons that carry oil or other hazardous materials in bulk as cargo, a term which includes our tank barges, are subject to liability limits of the greater of $1,200 per gross ton or $10 million. For any vessels, other than "tank vessels," that are subject to OPA 90, the liability limits are the greater of $0.5 million or $600 per gross ton. A party cannot take advantage of liability limits if the spill was caused by gross negligence or willful misconduct or resulted from violation of a federal safety, construction or operating regulation. If the party fails to report a spill or to cooperate fully in the cleanup, the liability limits likewise do not apply. OPA 90 also imposes ongoing requirements on a responsible party, including preparedness and prevention of oil spills, preparation of an oil spill response plan and proof of financial responsibility (to cover at least some costs in a potential spill) for vessels in excess of 300 gross tons. We have engaged the National Response Corporation to serve as our independent contractor for purposes of providing stand-by oil spill response services in all geographical areas of our fleet operations. In addition, our Oil Spill Response Plan has been approved by the U.S. Coast Guard. Finally, we have provided satisfactory evidence of financial responsibility to the U.S. Coast Guard for all of our vessels over 300 tons. OPA 90 requires that all newly-built tank vessels used in the transport of petroleum products be built with double hulls and provides for a phase-out period for existing single-hull vessels. Modifying existing vessels to provide for double hulls will be required of all tank barges and tankers in the industry by the year 2015. We are in a favorable position concerning this provision because a significant number of vessels in our fleet of tank barges measure less than 5,000 gross tons. Vessels of such tonnage may continue to operate without double hulls through the year 2015. Under existing legal requirements, therefore, we will be required to modify or replace only five of our tank barges before 2015. Although we are not aware of anything that would lead us to believe this current schedule will change, it remains possible that a change in the law affecting the requirement for double-hulls or other aspects of our operations may occur that would require us to modify or replace our existing tank barge fleet earlier than currently anticipated. The Clean Water Act imposes strict controls on the discharge of pollutants into the navigable waters of the United States. The Clean Water Act also provides for civil, criminal and administrative penalties for any unauthorized discharge of oil or other hazardous substances in reportable quantities and imposes substantial liability for the costs of removal and remediation of an unauthorized discharge. Many states have laws that are analogous to the Clean Water Act and also require remediation of accidental releases of petroleum in reportable quantities. Our vessels routinely transport diesel fuel to offshore rigs and platforms and also carry diesel fuel for their own use. Our supply boats transport bulk chemical materials used in drilling activities and 47

liquid mud, which contains oil and oil by-products. We maintain vessel response plans as required by the Clean Water Act to address potential oil spills. The Comprehensive Environmental Response, Compensation, and Liability Act of 1980, also known as "CERCLA" or "Superfund," and similar laws impose liability for releases of hazardous substances into the environment. CERCLA currently exempts crude oil from the definition of hazardous substances for purposes of the statute, but our operations may involve the use or handling of other materials that may be classified as hazardous substances. CERCLA assigns strict liability to each responsible party for all response and remediation costs, as well as natural resource damages and thus we could be held liable for releases of hazardous substances that resulted from operations by third parties not under our control or for releases associated with practices performed by us or others that were standard in the industry at the time. The Resource Conservation and Recovery Act regulates the generation, transportation, storage, treatment and disposal of onshore hazardous and non-hazardous wastes and requires states to develop programs to ensure the safe disposal of wastes. We generate non-hazardous wastes and small quantities of hazardous wastes in connection with routine operations. We believe that all of the wastes that we generate are handled in all material respects in compliance with the Resource Conservation and Recovery Act and analogous state statutes. In or around early September 2000, LEEVAC Marine, one of our subsidiaries, the name of which was recently charged to Hornbeck Offshore Transportation, was one of approximately 130 companies that received a letter from the U.S. Environmental Protection Agency, or EPA, directing LEEVAC Marine to respond to a CERCLA 104(e) information request on hazardous substances that may have been sent by it to the Palmer Barge Line Site in Port Arthur, Texas. The Palmer Barge Line site was listed as a federal Superfund site in July 2000. According to records furnished by EPA in mid-September 2000, LEEVAC Marine allegedly had two tank cleaning jobs performed at this site in September-October 1988 (which was before LEEVAC Marine became one of our subsidiaries) at a cost of approximately $12,000. In early September 2001, the EPA sent a letter addressed to LEEVAC Marine, identifying it as a party that may be responsible for cleanup of the Palmer Barge Line Site. Our subsidiary subsequently had further communications with the EPA on the alleged connection between the two tank cleaning jobs and responsibility for cleanup of the Palmer Barge Line Site. In late September 2001, the EPA sent another letter addressed to LEEVAC Marine notifying the company that it is no longer identified as a potentially responsible party in this matter. Consequently, we do not believe that we will have any ultimate liability with respect to this matter. LEEVAC Marine was notified in March 1996 regarding the possibility of remediating on a voluntary basis certain waste pits at the SBA Shipyards site in Jennings, Louisiana. This site is not identified as a Superfund site. Subsequent to this initial notice, in December 2000, LEEVAC Marine was one of approximately 14 companies that formed a limited liability company, SSCI Remediation, LLC, to address this matter. LEEVAC Marine accrued a $97,500 liability at the time of our formation to cover this expense. Our subsidiary's current percentage of liability for cleanup efforts at this site is estimated at approximately 2.64%, and, to date, it has contributed approximately $34,000 towards this cleanup effort, thereby reducing the accrued liability to $63,500. This $34,000 contribution represents our subsidiary's current share of a $2 million voluntary cleanup plan submitted to the limited liability company's members by an independent contractor who has agreed to clean up the site in a manner that will meet both state and federal standards. Remedial activities have begun at the SBA Shipyards site. In June 1997, Cari Investment Company agreed to indemnify us for certain matters, including those discussed in this paragraph. The indemnity would be applicable to all liabilities, obligations, damages and expenses related to the Superfund matter and to all other liabilities, obligations, damages and expenses in excess of $0.1 million. Christian G. Vaccari, who served as our Chairman and Chief Executive Officer until February 2002 and is serving as one of our directors until his resignation becomes effective at the closing of this offering, is a minority shareholder and President, Chief 48

Executive Officer and Chairman of the Board of Cari Investment Company. In July 2002, Hornbeck Offshore Transportation entered into a contractual agreement whereby it paid an additional $17,000 to SSCI Remediation, LLC in order to limit its exposure to certain future costs incurred by the independent contractor at the site. This limitation on payment of future monies relates primarily to certain legal and administrative costs of SSCI Remediation, LLC and does not bar future payment of monies for Superfund cleanup costs or for costs associated with any suits brought by third parties. Payment of the $17,000 has decreased Hornbeck Offshore Transportation's accrual for environmental liability to $46,500. The Outer Continental Shelf Lands Act gives the federal government broad discretion to regulate the release of offshore resources of oil and natural gas. Because our operations rely primarily on offshore oil and natural gas exploration, development and production, if the government were to exercise its authority under the Outer Continental Shelf Lands Act to restrict the availability of offshore oil and natural gas leases, such an action would have a material adverse effect on our financial condition and results of operations. In addition to laws and regulations affecting us directly, our operations are also influenced by laws, regulations and policies which affect our customers' drilling programs and the oil and natural gas industry as a whole. We currently have in place pollution insurance coverage for oil spills in navigable waters of the United States. Our 11 OSVs have $5 million in primary insurance coverage for such offshore oil spills, with an additional $100 million in excess umbrella coverage. In addition, 15 of our 16 tank barges have $10 million in primary insurance coverage for such offshore oil spills, with an excess umbrella coverage of $1 billion. Our sixteenth tank barge is leased under a bareboat charter, and the operator of that tank barge is responsible for insuring the tank barge for offshore oil spills. Finally, our 13 tugs have $5 million in primary insurance coverage for these offshore oil spills, with an excess umbrella coverage of $1 billion. Our tugs and tank barges acquired from the Spentonbush/Red Star Group have obtained ISO 14001 certifications for environmental management from the International Standards Organization. Both of our principal office locations in Mandeville, Louisiana and Brooklyn, New York, as well as the majority of our vessels, including all of our OSVs and our tugs and tank barges acquired from the Spentonbush/Red Star Group, are also certified under the International Safety Management Code, developed by the International Maritime Organization to provide internationally recognized standards for the safe management and operation of ships and for pollution prevention. Our other tugs and tank barges participate in the Responsible Carrier Program developed by the American Waterways Operators to improve marine safety and environmental protection in the tank barge industry. Our OSVs participate in the U.S. Coast Guard's Streamlined Inspection Program to maintain the overall quality of our vessels and their operating systems. We believe that our voluntary attainment and maintenance of these certifications and participation in these programs provides evidence of our commitment to operate in a manner that minimizes our impact on the environment. In connection with the terrorist attacks in New York on September 11, 2001, certain of our tugs operating in New York Harbor were requisitioned by the U.S. Coast Guard for four days pursuant to federal law authorizing the requisition of U.S. owned vessels in a national emergency. The loss of revenues associated with such requisition by the Coast Guard did not have a material adverse impact on our financial condition or results of operations, and we chose not to pursue a claim. OPERATING HAZARDS AND INSURANCE The operation of our vessels is subject to various risks, such as catastrophic marine disaster, adverse weather conditions, mechanical failure, collision and navigation errors, all of which represent a threat to personnel safety and to our vessels and cargo. We maintain 49

insurance coverage that we consider customary in the industry against certain of these risks, including, as discussed above, $1 billion in pollution insurance for the tug and tank barge fleet and $100 million of pollution coverage for the OSVs. We believe that our current level of insurance is adequate for our business and consistent with industry practice, and we have not experienced a loss in excess of our policy limits. We may not be able to obtain insurance coverage in the future to cover all risks inherent in our business, or insurance, if available, may be at rates that we do not consider to be commercially reasonable. In addition, as more single-hulled vessels are retired from active service, insurers may be less willing to insure and customers less willing to hire single-hulled vessels. EMPLOYEES On July 1, 2002, we had 412 employees in the United States and Puerto Rico, including 350 operating personnel and 62 corporate, administrative and management personnel. None of our employees are represented by a union or employed pursuant to a collective bargaining agreement or similar arrangement. In July 2001, the International Organization of Masters, Mates and Pilots, ILA, AFL-CIO, initiated an action to organize a union that would include 30 of our fleet and technical employees in Puerto Rico. We contested the action with the regional office of the National Labor Relations Board, or NLRB, and engaged in a campaign to educate our employees with regard to the issues related to the action. Our Puerto Rican employees held an election on the matter in October 2001. The results of the election were announced on July 11, 2002, with our Puerto Rican employees voting not to unionize. The union had until July 19, 2002 to file an objection with the NLRB with respect to the election results. No such objection was filed. We have been advised that the NLRB will certify as final the results of the election. We have not experienced any strikes or work stoppages, and our management believes that we continue to enjoy good relations with our employees. PROPERTIES Our corporate headquarters are located in Mandeville, Louisiana in two leased facilities which house our principal executive and administrative offices. One facility consists of approximately 6,500 square feet and is held under a nine-month lease, and the other consists of approximately 3,600 square feet and is held under a month-to-month lease. We also hold a one-year lease on a 4,500 square foot warehouse near our corporate headquarters to maintain spare parts inventory. For local support in Puerto Rico, we lease an office consisting of approximately 1,900 square feet. To support our operations in the northeastern United States, we lease office space and warehouse space in Brooklyn, New York, consisting of approximately 66,760 square feet. We also lease dock space, consisting of approximately 36,000 square feet, in Brooklyn, New York. We operate our tug and tank barge fleet from these New York facilities. The lease on the dock space expires in 2006. We believe that our facilities, including waterfront locations used for vessel dockage and certain vessel repair work, provide an adequate base of operations for the foreseeable future. Information regarding our fleet is set forth above in " -- Offshore Supply Vessels -- Our OSV Business" and " -- Tugs and Tank Barges -- Our Tug and Tank Barge Business." LEGAL PROCEEDINGS We are not currently a party to any material legal proceedings, although we may from time to time be subject to various legal proceedings and claims that arise in the ordinary course of business. 50

SEASONALITY OF BUSINESS Demand for our OSV services is directly affected by the levels of offshore drilling activity. Budgets of many of our customers are based upon a calendar year, and demand for our services has historically been stronger in the third and fourth calendar quarters when allocated budgets are expended by our customers and weather conditions are more favorable for offshore activities. Many other factors, such as the expiration of drilling leases and the supply of and demand for oil and natural gas, may affect this general trend in any particular year. These factors have less impact on our OSV business due to our high level of contracted cash flow, which has resulted in high utilization. Tank barge services are significantly affected by demand for refined petroleum products and crude oil. Such demand is seasonal and often dependent on weather conditions. Unseasonably mild winters result in significantly lower demand for heating oil in the northeastern United States, which is a significant market for our tank barge services. Conversely, the summer driving season can increase demand for automobile fuel and, accordingly, the demand for our services. While The recent winter season was the warmest on record and adversely affected the volume of products we transported in the northeastern United States in the fourth quarter of 2001 and the first quarter of 2002. 51

Each non-employee director will be entitled to receive a total annual retainer of $20,000, paid quarterly. Each non-employee director will also receive $1,200 for each board meeting attended in person and $800 for each board meeting attended by telephonic communications. Board committee members will be entitled to receive $600 for each committee meeting attended, with the committee chairman entitled to receive $800 for each committee meeting attended. Committee members must attend meetings in person or by telephonic communications to receive the applicable compensation. Non-employee directors will receive a minimum annual grant of 5,000 options to purchase common stock which amount may be reviewed annually and increased at the discretion of the compensation committee. After three years of service as a non-employee director, a non-employee director and his immediate family may elect to participate in the same insurance benefit programs sponsored by the company on the same monetary terms as the executive officers. The compensation plan also provides for longevity service awards to non-employee directors. Upon completion of three years of service following adoption of the compensation plan, a director will be granted options to purchase the number of shares of common stock equaling 25% of the options granted to such director over the previous three years. Upon completion of five years of service as a non-employee director, a director will be granted options to purchase the number of shares of common stock equaling 50% of the options granted to such director over the previous five years less the number of shares covered by the options awarded to such director after three years of service. Thereafter, upon completion of each successive period of five years of service, a non-employee director will be granted options to purchase the number of shares of common stock equaling 50% of the options granted to such director over the previous five years. Under the terms of this compensation plan, neither Mr. Cryar nor Mr. Vaccani qualifies to participate. As compensation for their service as directors during 2001, in March 2002 each of Messrs. Cryar, Larry Hornbeck, Hunt and Waite were granted options to purchase 20,000 shares of our common stock at an exercise price of $2.65 per share. In March 2002, Mr. Stewart was also granted options to purchase 10,000 shares of our common stock at an exercise price of 55

$2.65 per share in connection with his service as director in 2001. One fourth of these options was exercisable as of the date of grant and one-fourth will become exercisable on each of the three following anniversaries of such dates. Also, during 2001, Messrs. Waite and Larry Hornbeck were each granted options to purchase 10,000 shares of our common stock at an exercise price of $2.65 per share in connection with the commencement of their service as directors. One-fifth of these options granted to Messrs. Waite and Larry Hornbeck was exercisable as of the date of the grant and one-fifth will become exercisable on each of the four following anniversaries of such dates. On February 27, 2002, we entered into an advisory agreement with Bernie W. Stewart, our Chairman of the Board. Under the terms of this agreement, Mr. Stewart advises and makes recommendations to our executive officers and board of directors on matters relating to our business, including our operations, finances, strategic planning and acquisitions. Mr. Stewart provided these services on a full-time basis through May 31, 2002 and is providing these services on a part-time basis through February 27, 2003. He received $20,000 per month for his full-time advisory services and will receive $8,335 per month for his part-time services. In addition to the options granted to Mr. Stewart described above, under the terms of his advisory agreement Mr. Stewart was granted options to purchase 10,000 shares of our common stock at an exercise price of $2.65 per share. Also under the terms of the advisory agreement, Mr. Stewart purchased 75,472 shares of our common stock at a purchase price of $2.65 per share, and, upon such purchase, we granted Mr. Stewart an option to purchase 37,736 shares of our common stock at a purchase price of $2.65 per share, which option shall be exercised in accordance with, and subject to the terms of, the terms and conditions of our Incentive Compensation Plan. If we terminate the agreement for any reason other than for cause, or if Mr. Stewart terminates the agreement for cause, he will be entitled to receive his advisory fees for the remainder of the original term of the agreement. Mr. Stewart has agreed that during the term of his advisory agreement he will not be employed by or associated with or own more than five percent (5%) of the outstanding securities of any entity which competes with us. Mr. Stewart has also agreed that during the term of the advisory agreement and for a period of two years after he will not (i) solicit any of our employees, customers, suppliers or sales agents to terminate their relationship with us or (ii) employ or cause any of our competitors to employ any person who is or was recently one of our employees, sales representatives, contractors, advisors or agents. 56

- --------------- (1) The options were granted at or above the fair market value of our common stock on the date of grant. (2) In accordance with the rules of the Securities and Exchange Commission, the gains or "option spreads" that would exist for the respective options granted are shown. These gains are based on the assumed rates of annual compound stock price appreciation of 5% and 10% from the date the option was granted over the full option term. These assumed annual compound rates of stock price appreciation are mandated by the rules of the Securities and Exchange Commission and do not represent our estimate or projection of future appreciation. (3) One-fifth of these options are exercisable as of the date of grant, and one-fifth become exercisable on each of the first, second, third and fourth anniversaries of the date of grant, provided, however, that any of these options that are not exercisable will become exercisable upon completion of this offering.

Annessa serves as our Vice President and Chief Operating Officer, James O. Harp, Jr. serves as our Vice President and Chief Financial Officer, and Paul M. Ordogne serves as our Treasurer, each under an employment agreement with an initial term expiring December 31, 2003. On January 1, 2003, and on every third January 1 (or second January 1 in the case of Mr. Ordogne) thereafter, each agreement will automatically renew for up to three additional years (two years in the case of Mr. Ordogne), unless terminated before any such renewal date by the employee or us. The employment agreements of Messrs. Hornbeck, Annessa, Harp and Ordogne currently provide for annual base salaries of $200,000, $170,000, $170,000 and $116,000, respectively. Our board has agreed to award a bonus or bonuses to each of Messrs. Hornbeck, Annessa and Harp if our company meets certain EBITDA and earnings per share targets with respect to any year during which their respective employment agreement is in effect. Our board may, in its discretion, award a smaller bonus if our company does not meet such targets or an additional bonus if our company exceeds such targets. Mr. Ordogne is eligible for a bonus each year at the discretion of the board. Under each of their respective employment agreements, the employee's salary will be reviewed from time to time by our compensation committee for possible increases based on the employee's performance. If we terminate the employment of Mr. Hornbeck for any reason other than for cause, he will be entitled to receive his salary until the actual termination date of his agreement or two years after the date of termination, whichever is later. If we terminate the employment of Messrs. Annessa, Harp or Ordogne for any reason other than for cause, he will be entitled to receive his salary until the actual termination date of his agreement or one year, as to Messrs. Annessa and Harp, and six months, as to Mr. Ordogne, after the date of termination, whichever is later. If we should undergo a change in control while the agreements are in effect and Messrs. Hornbeck, Annessa or Harp is either constructively or actually terminated under the conditions set forth in his agreement, then he will be entitled to receive three times his salary for 59

the year in which the termination occurs and, in general, three times the bonus he received for the previous year. If we should undergo a change in control while Mr. Ordogne's agreement is in effect and he is either constructively or actually terminated under the conditions set forth in his agreement, then he will be entitled to receive one and one-half times his salary for the year in which the termination occurs and, in general, one and one-half times the bonus he received for the previous year. Mr. Hornbeck has agreed that during the term of his agreement and Messrs. Annessa, Harp and Ordogne have each agreed that during the term of their respective agreements and for a period of one year (six months in the case of Mr. Ordogne) after termination, they will not (i) be employed by or associated with or own more than five percent (5%) of the outstanding securities of any entity which competes with us in the locations in which we operate, (ii) solicit any of our employees to terminate their employment or (iii) accept employment with or payments from any of our clients or customers who did business with us while employed by us. We may elect to extend Mr. Annessa's noncompetition period for an additional year by paying his compensation and other benefits for an additional year, and we may elect to extend Mr. Ordogne's noncompetition period for an additional six months by paying his compensation and other benefits for an additional six months. Christian G. Vaccari served as our Chairman of the Board and Chief Executive Officer under an employment agreement with terms substantially identical to the terms of Mr. Hornbeck's employment agreement described above. Effective February 27, 2002, Mr. Vaccari ceased serving as our Chairman of the Board and Chief Executive Officer, his employment under the terms of his agreement terminated and he continues to receive payments in accordance with the termination provisions of his agreement. INCENTIVE COMPENSATION PLAN Our board of directors and shareholders adopted an Incentive Compensation Plan in 1997. The purpose of the Incentive Compensation Plan is to strengthen our company by providing an incentive to our employees, officers, consultants, non-employee directors and advisors to devote their abilities and energies to our success. The plan provides for the granting or awarding of incentive and nonqualified stock options, stock appreciation and dividend equivalent rights, restricted stock and performance shares. With the approval of our stockholders, we have reserved 3.5 million shares of our common stock for issuance pursuant to awards made under the plan, of which 1,428,764 shares are available for future grants. The Incentive Compensation Plan is administered by the compensation committee. Subject to the express provisions of the plan, the compensation committee has full authority, among other things: - to select the persons to whom stock, options and other awards will be granted, - to determine the type, size and terms and conditions of stock options and other awards and - to establish the terms for treatment of stock options and other awards upon a termination of employment. Under the plan, awards other than stock options and stock appreciation rights given to any of our executive officers whose compensation must be disclosed in our annual proxy statement and who is subject to the limitations imposed by Section 162(m) of the tax code must be based on the attainment of certain performance goals established by the board or the compensation committee. The performance measures are limited to earnings per share, return on assets, return on equity, return on capital, net profit after taxes, net profits before taxes, operating profits, stock price and sales or expenses. Additionally, the performance goals must include formulas for calculating the amount of compensation payable if the goals are met; both the goals and the 60

formulas must be sufficiently objective so that a third party with knowledge of the relevant performance results could assess that the goals were met and calculate the amount to be paid. Consistent with certain provisions of the tax code, there are other restrictions providing for a maximum number of shares that may be granted in any one year to a named executive officer and a maximum amount of compensation payable as an award under the plan (other than stock options and stock appreciation rights) to a named executive officer. 401(K) RETIREMENT PLAN We have adopted a 401(k) plan for our employees. Employees are eligible to participate in the plan following three months of employment with us if they are at least 21 years of age. Under the plan, eligible employees are permitted, subject to legal limitations, to contribute up to 20% of compensation. The plan provides that we will match an amount equal to a percentage set by us of up to 6% of an employee's contribution before the end of each calendar year. We are also permitted to make qualified non-elective and discretionary contributions in proportion to each eligible employee's compensation as a ratio of the aggregate compensation of all eligible employees. The amounts held under the plan are invested in investment funds maintained under the plan in accordance with the directions of each participant. This plan does not permit investments in our common stock. All employees' contributions are immediately 100% vested. Contributions by us to the plan vest at a rate of 20% each year after the second year of service. Upon attaining age 65, participants are automatically 100% vested, even with respect to our contributions. Subject to certain limitations imposed under the tax code, participants or their designated beneficiaries are entitled to payment of vested benefits upon termination of employment. On attaining age 65, participants are entitled to distribution of the full value of their benefits even if they continue to be employed by us. Such employees also have the option of deferring payment until April 1 following the year they attain the age of 70 1/2. In addition, hardship and other in-service distributions are available under certain circumstances and subject to certain conditions. The amount of benefits ultimately payable to a participant under the plan depends on the level of the participant's salary deferral contributions under the plan, the amount of our discretionary and matching contributions made to the plan and the performance of the investment funds maintained under the plan in which participants are invested. 61

CERTAIN TRANSACTIONS WITH RELATED PARTIES The following is a discussion of transactions between our company and its executive officers, directors and shareholders owning more than 5% of our common stock. We believe that the terms of each of these transactions were at least as favorable as could have been obtained in similar transactions with unaffiliated third parties. Effective May 29, 2002, we changed our name to Hornbeck Offshore Services, Inc. from HORNBECK-LEEVAC Marine Services, Inc., and one of our subsidiaries changed its name to Hornbeck Offshore Transportation, LLC for LEEVAC Marine, LLC. In connection with these name changes, we terminated a cross-license with Cari Investment Company covering the use of the name "LEEVAC" and certain logos associated with such name, and assigned all of our interests therein to Cari Investment Company. In consideration, Cari Investment Company agreed not to use the name "LEEVAC" or its related logos in any activity that would compete with our business. Cari Investment Company is a holder of more than 5% of our common stock and Christian G. Vaccari, who served as our Chairman of the Board and Chief Executive Officer until February 2002 and who will serve as one of our directors until his resignation becomes effective at the closing of this offering, is the President, Chief Executive Officer and Chairman of the Board of Cari Investment Company. Mr. Vaccari is also a member of LEEVAC Industries, LLC. Four of our offshore supply vessels delivered since January 1, 2001 were built by LEEVAC Industries. As of June 1, 2002, we had contracts with LEEVAC Industries for the construction of four additional offshore supply vessels, which are the first four vessels to be constructed under our current eight-vessel newbuild program. Since January 1, 2001, we have made payments under our various shipyard contracts with LEEVAC Industries aggregating $36.3 million, and at July 1, 2002 our contracts with LEEVAC Industries call for the payment of an additional $34.2 million over the course of construction of the four offshore supply vessels. Our current and past contracts with LEEVAC Industries were entered into following a competitive bidding process. In connection with our contract with LEEVAC Industries relating to the construction of the first four vessels under our current newbuild program, we received a favorable fairness opinion from an independent appraiser with respect to the terms of the transaction. On June 5, 1998, Enron North America Corp. and Joint Energy Development Investments II Limited Partnership entered into an agreement with us and two of our subsidiaries, Hornbeck Offshore Services, Inc. and LEEVAC Marine Inc. (now known as Hornbeck Offshore Services, LLC and Hornbeck Offshore Transportation, LLC, respectively), pursuant to which Enron North America and Joint Energy Development Investments agreed to lend these subsidiaries $20 million. In connection with this facility, our subsidiaries issued to each of Enron North America and Joint Energy Development Investments a promissory note in the amount of $10 million, each bearing interest at 7% annually. ENA CLO I Holding Company I L.P., an affiliate of Enron North America, subsequently succeeded to the interests, obligations, duties and rights of both Joint Energy Development Investments and Enron North America as lenders under this facility. These notes were paid in full in July 2001 with proceeds from the private placement of our senior notes and this credit facility has been terminated. In connection with this facility, Enron North America and Joint Energy Development Investments were each issued warrants to purchase shares of our common stock and, as a result of holding such warrants, became the beneficial owners of more than 5% of our common stock. On October 25, 2001, we repurchased all of the warrants for an aggregate purchase price of $14.5 million. In order to finance the repurchase of the warrants, we completed a private placement of $14.6 million of our common stock. In connection with Richard Cryar's resignation from our board of directors, the board approved an amendment to his outstanding stock options providing for full vesting at the closing of this offering of any unvested options previously granted to Mr. Cryar. As a result, options covering 21,000 shares of our common stock that were not exercisable at the time Mr. Cryar tendered his resignation will become exercisable at the closing of this offering. 62

We have entered into registration rights agreements, voting agreements and stockholders agreements with Todd M. Hornbeck, Troy A. Hornbeck, Cari Investment Company and SCF-IV, L.P. Please read the sections entitled "Principal and Selling Stockholders -- Voting Agreements," "Description of Capital Stock -- Common Stock," "-- Registration Rights" and "-- Anti-Takeover Effects of Certificate, Bylaws, Stockholder Rights Plan and Delaware Law" for information regarding the terms of these agreements. 63

PRINCIPAL AND SELLING STOCKHOLDERS The following table sets forth certain information regarding the beneficial ownership of our voting securities as of July 18, 2002 and as adjusted to reflect the sale of the shares of our common stock offered pursuant to this prospectus by: - each person who is known to us to be the beneficial owner of more than 5% of our voting securities; - each of our directors; - each of our executive officers and all of our executive officers and directors as a group; and - each selling stockholder who is not also a director, executive officer or the beneficial owner of more than 5% of our voting securities. The number of shares listed in the table as being offered is allocated based on preliminary indications from selling stockholders of the number of shares they wish to sell, assuming an offering by all selling stockholders of shares. These amounts are subject to change until the selling stockholders enter into binding agreements regarding their shares. The directors and executive officers of the company, other than Mr. Vaccari, are not selling shares in this offering. Additionally, SCF-IV, L.P. and the William Herbert Hunt Trust Estate will not be selling more than 33 1/3% of the shares of our common stock that they own, respectively. 64

Unless otherwise indicated, each person named below has an address in care of our principal executive offices and has sole power to vote and dispose of the shares of voting securities beneficially owned by them, subject to community property laws where applicable. The table below assumes that the underwriters do not purchase additional shares of common stock from us in this offering to cover over-allotments. It is therefore based on 30,301,036 shares of our common stock outstanding prior to this offering and shares outstanding immediately after this offering.

DESCRIPTION OF CAPITAL STOCK GENERAL The following description of our capital stock, our certificate of incorporation and bylaws is only a summary. For more complete information, you should refer to our certificate of incorporation and bylaws, which we have filed with the Securities and Exchange Commission as exhibits to the registration statement of which this prospectus is a part. In addition, you should refer to the general corporation laws of Delaware, which also govern our structure, management and activities. As of July 1, 2002, our authorized capital stock consisted of: - 100,000,000 shares of common stock, par value $.01 per share, of which 30,301,036 were outstanding and held by approximately 75 holders of record; and - 5,000,000 shares of preferred stock, par value $.01 per share, of which will be designated as Series A Junior Participating Preferred Stock in connection with the stockholder rights plan discussed below, but none are currently outstanding. One of the consequences of our authorized but unissued common and preferred stock may be to enable our board to make more difficult or to discourage an attempt to obtain control of our company. Use of the common or preferred stock for this purpose might also protect incumbent management. Before this offering, there has been no public market for our common stock. Although we intend to apply to list the common stock on the , we cannot assure you that a market for our common stock will develop or, if one develops, that it will be sustained. COMMON STOCK General. The holders of common stock are entitled to one vote per share on all matters submitted to a vote of our stockholders. Stockholders are not permitted to cumulate their votes. With certain exceptions, which are described below, a majority of the votes entitled to be cast and represented in person or by proxy at a meeting of stockholders is required to approve any matter on which stockholders vote. The affirmative vote of holders of at least 80% of the shares entitled to vote is required to approve certain amendments to our certificate of incorporation and bylaws. See "-- Anti-Takeover Effects of Certificate, Bylaws, Stockholder Rights Plan and Delaware Law -- Board of Directors." The affirmative vote of holders of at least 66 2/3% of the shares entitled to vote is required to approve or authorize: - a merger or consolidation with any other corporation; - the sale, lease, exchange or other disposition of all or substantially all of our assets; - a liquidation of our company; or - any amendments to our certificate of incorporation other than those indicated in this paragraph. The holders of common stock are entitled to receive ratably such dividends as may be declared from time to time by our board out of funds legally available for the payment of dividends, subject to preferences that may be applicable to any outstanding preferred stock. The indenture governing our senior notes and the agreement governing our revolving line of credit limit and in some circumstances prohibit our ability to declare or pay dividends. If we liquidate, dissolve or otherwise wind up our business, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities and satisfaction of prior distribution rights of preferred stock, if any is then outstanding. The holders of common stock have no preemptive or conversion rights or other subscription rights, and there are no redemption or 67

sinking fund provisions applicable to the common stock. All of the outstanding shares of common stock are fully paid and nonassessable, and the shares of common stock to be issued upon completion of this offering will be fully paid and nonassessable. Voting Agreements. Under the terms of a stockholders' agreement entered into October 27, 2000 among SCF-IV, L.P., Todd M. Hornbeck, Troy A. Hornbeck, Cari Investment Company and the company, Todd and Troy Hornbeck and Cari Investment Company have agreed to vote their shares in favor of SCF-IV, L.P.'s designee to our board, so long as it owns at least 5% of the company's outstanding common stock or, prior to an initial public offering, it owns at least 80% of the common stock it acquired in November 2000. Under this agreement, SCF-IV, L.P. also agrees to vote its shares in favor of the two designees of Todd and Troy Hornbeck and the two designees of Cari Investment Company. Pursuant to a voting arrangement entered into between SCF-IV, L.P. and the company in connection with our private equity offering completed in October 2001, SCF is restricted from voting 562,081 of its shares. See also "Business -- Environmental and Other Governmental Regulation" for a discussion of restrictions on foreign ownership of our stock. PREFERRED STOCK Our board, without further action by our stockholders, is authorized to issue preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions of the preferred stock, including: - dividends rights; - conversion rights; - voting powers; - redemption rights; and - liquidation preferences. The issuance of preferred stock provides us with flexibility in achieving various corporate purposes, including possible acquisitions, but it could adversely affect the voting rights of holders of common stock. It could also affect the likelihood that holders of common stock will receive dividends or payments upon liquidation. A total of shares of preferred stock will be designated as Series A Junior Participating Preferred Stock, which we refer to as "the Series A Preferred Stock", in connection with our stockholder rights plan discussed below. No other series of preferred stock is designated and no shares of preferred stock are outstanding. REGISTRATION RIGHTS Under the terms of a stockholders' agreement among us, Todd M. Hornbeck, Troy A. Hornbeck and Cari Investment Company, Todd and Troy Hornbeck and Cari Investment Company are entitled to require us to file a registration statement under the Securities Act of 1933 to sell some or all of the shares of our common stock held by them. We are only required to make one such stand-alone registration for each of Todd and Troy Hornbeck and one for Cari Investment Company. In addition, holders of a majority of the shares of our common stock issued to the Hornbecks and Cari Investment Company on June 5, 1997 and shares issued with equivalent registration rights to other persons or entities may require us to register some or all of such shares if they have not already been registered and may not then be sold under Rule 144(k) of the Securities Act of 1933. Todd and Troy Hornbeck and Cari Investment Company also have the right to include some or all of their shares of common stock in any other registration statement that we file involving our common stock. 68

Under the terms of a registration rights agreement among us and SCF-IV, L.P., SCF-IV, L.P. and other stockholders that purchased shares of our common stock in the private placement of our common stock completed in November 2000 have the right to include some or all of such shares, and any shares issued in respect of such shares, in any registration statement that we file involving our common stock. Also under such agreement, the holders of 50.1% of the shares of our common stock issued in the November 2000 private placement, which, at this time, is only SCF-IV, L.P., are entitled to require us to file a registration statement under the Securities Act of 1933 to sell some or all of the common stock held by them. All persons with registration rights under the foregoing agreements have either elected to participate in this offering or have waived their rights to participate. TRANSFER AGENT AND REGISTRAR The transfer agent and registrar for our common stock is Mellon Investor Services LLC. ANTI-TAKEOVER EFFECTS OF CERTIFICATE, BYLAWS, STOCKHOLDER RIGHTS PLAN AND DELAWARE LAW General. Our certificate of incorporation and bylaws contain provisions and our board of directors has adopted a stockholder rights plan that are designed in part to make it more difficult and time-consuming for a person to obtain control of our company. The provisions of our certificate of incorporation, bylaws and stockholder rights plan reduce the vulnerability of our company to an unsolicited takeover proposal. On the other hand, these provisions may have an adverse effect on the ability of stockholders to influence the governance of our company. In addition, our certificate of incorporation contains provisions that enable our board to limit the amount of our common stock that may be owned by persons who are not U.S. citizens. See "Business -- Environmental and Other Governmental Regulation." This may adversely affect the liquidity of our common stock in certain situations. We have summarized the provisions of our certificate of incorporation and bylaws, other than those dealing with citizenship, and the terms of our stockholder rights plan below, but you should read our certificate of incorporation, bylaws and stockholder rights plan for a more complete description of the rights of holders of our common stock. Board of Directors. Our certificate of incorporation and bylaws divide the members of our board of directors into three classes serving three-year staggered terms. The classification of directors makes it more difficult for our stockholders to change the composition of our board: at least two annual meetings of stockholders may be required for the stockholders to change a majority of the directors, whether or not a majority of our stockholders favors such a change. The affirmative vote of the holders of at least eighty percent (80%) of the shares entitled to vote is required to alter or repeal the provision related to the classification of our board. Our stockholders may only remove directors from office for cause by the affirmative vote of stockholders holding at least 80% of the shares entitled to vote at an election of directors. Our stockholders may not remove directors without cause. Vacancies in a directorship may be filled only by the vote of a majority of the remaining directors, although if a director was removed by the stockholders, the vacancy may be filled at the meeting at which the removal took place, if the notice of such meeting specified that the vacancy would be filled by the stockholders, by the affirmative vote of stockholders holding at least 80% of the shares entitled to vote. The number of directors may be fixed by resolution of the board, but must be no less than four nor more than nine unless otherwise determined by holders of 80% of the shares entitled to vote at an election of directors or by unanimous consent of the board. Contractual Restrictions on Transfer by Certain Stockholders. Todd M. Hornbeck, Troy A. Hornbeck and Cari Investment Company have agreed, after we become a reporting company under the Securities Exchange Act of 1934, to give us notice of and an opportunity to make a competing offer regarding a decision by any of them to sell or consider accepting an offer to sell 69

to a single person or entity shares of common stock representing 5% or more of our common stock, other than in compliance with Rule 144 or to an affiliate or family member of the holder. SCF-IV, L.P. has also agreed to give us notice of and an opportunity to make a competing offer regarding a decision by it to sell or consider accepting an offer to sell to a single person or entity shares of common stock representing 5% or more of our common stock. SCF-IV, L.P. is further prohibited from transferring any of its shares of our common stock to any person or entity that is a competitor of ours. Supermajority Voting. The affirmative vote of the holders of at least 66 2/3% of our outstanding voting stock is required to amend or repeal our certificate of incorporation, except with respect to the classification of the board, which requires the affirmative vote of the holders of at least 80% of our outstanding voting stock. The affirmative vote of the holders of at least 80% of our outstanding voting stock is required to amend, alter, change or repeal the provisions in our bylaws governing the following matters: - the composition of the board of directors, including the classification of the board; - the removal of directors and the procedure for electing the successor to a removed director; - the date and time of the annual meeting; - advance notice of stockholder nominations and stockholder business; and - the procedure for calling a special meeting of stockholders. No Stockholder Action by Written Consent. Under Delaware law, unless a corporation's certificate of incorporation specifies otherwise, any action that could be taken at an annual or special meeting of stockholders may be taken without a meeting and without notice to or a vote of other stockholders if a consent in writing is signed by holders of outstanding stock having voting power sufficient to take such action at a meeting at which all outstanding shares were present and voted. Our certificate of incorporation provides that stockholder action may be taken only at an annual or special meeting of stockholders. As a result, our stockholders may not act upon any matter except at a duly called meeting. Advance Notice of Stockholder Nominations and Stockholder Business. Our stockholders may nominate a person for election as a director or bring other business before a stockholder meeting only if written notice of an intent to do so is given at a specified time in advance of the meeting. Special Meetings of the Stockholders. Special meetings of the stockholders may be called only by the chairman of the board, the chief executive officer, the president, a majority of the directors or holders of not less than 25% of the shares entitled to vote at the meeting. Stockholder Rights Plan. Our board approved the form of a stockholder rights plan on July 18, 2002, a copy of which will be filed with the Commission, in anticipation of declaring a dividend of one right for each outstanding share of our common stock to stockholders of record on completion of this offering. Once a dividend of the rights is declared, the rights will only become exercisable, and transferable apart from our common stock, 10 business days following a public announcement that a person or group has acquired beneficial ownership of, or has commenced a tender or exchange offer for, 15% or more of our common stock. The discussion that follows sets forth the operation of the rights once the dividend of the rights has been declared and the rights have been issued to the stockholders. Each right will initially entitle the holder to purchase one one-hundredth of one share of our Series A Preferred Stock at a price to be determined, subject to adjustment. In the event that a person becomes a 15% or more holder whose acquisition of 15% or more of common stock triggered the exercise of the rights of our common stock, each holder of a right (other than the 70

person whose acquisition of 15% or more of common stock triggered the exercise of the rights) will be entitled, instead, to receive upon exercise of each right a number of shares of our common stock (or, in certain circumstances, cash, property or other securities of us) having a current market price equal to twice the exercise price for one one-hundredth of a share of Series A Preferred Stock. Similarly, if after an event triggering the exercise of the rights we are acquired in a merger or other business combination, or 50% or more of our assets or earning power are sold or transferred, each right will entitle the holder thereof (other than the person whose acquisition of 15% or more of common stock triggered the exercise of the rights) to receive a number of shares of common stock of the company acquiring us having a current market price equal to twice the exercise price for one one-hundredth of a share of Series A Preferred Stock. We may redeem the rights in whole, but not in part, at a redemption price of $.01 per right at any time before the rights become exercisable. The rights will expire 10 years from the record date to be set for the dividend of the rights. Pursuant to the stockholder rights plan, all shares of our Series A Preferred Stock, once established, will be reserved for issuance upon exercise of rights. The rights have certain anti-takeover effects. The rights will cause substantial dilution to a person or group who attempts to acquire us without the approval of our board of directors. As a result, the overall effect of the rights may be to render more difficult or discourage any attempt to acquire us even if such acquisition may be favorable to the interests of our stockholders. Because our board of directors can redeem the rights or approve certain offers, the rights should not interfere with any merger or other business combination approved by our board of directors. The description and terms of the rights are set forth in a Rights Agreement to be entered into between the company and Mellon Investor Services, LLC, which serves as the rights agent. Delaware Business Combination Statute. Section 203 of the Delaware General Corporation Law provides that, subject to specified exceptions, an "interested stockholder" of a Delaware corporation may not engage in any "business combination," including general mergers or consolidations or acquisitions of additional shares of the corporation, with the corporation for a three-year period following the time that such stockholder becomes an interested stockholder unless: - before such time, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; - upon consummation of the transaction which resulted in the stockholder becoming an "interested stockholder," the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding specified shares; or - on or after such time, the business combination is approved by the board of directors of the corporation and authorized not by written consent, but at an annual or special meeting of stockholders, by the affirmative vote of at least 66 2/3% of the outstanding voting stock not owned by the interested stockholder. Under Section 203, the restrictions described above also do not apply to specified business combinations proposed by an interested stockholder following the announcement or notification of a transaction specified in Section 203 and involving the corporation and a person who: - had not been an interested stockholder during the previous three years; or - became an interested stockholder with the approval of a majority of the corporation's directors, 71

if such transaction is approved or not opposed by a majority of the directors who were directors prior to any person becoming an interested stockholder during the previous three years or were recommended for election or elected to succeed such directors by a majority of such directors. Except as otherwise specified in Section 203, an "interested stockholder" is defined to include: - any person that is the owner of 15% or more of the outstanding voting stock of the corporation, or is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within three years immediately before the date of determination; and - the affiliates and associates of any such person. Under some circumstances, Section 203 makes it more difficult for an interested stockholder to effect various business combinations with a corporation for a three-year period. INDEMNIFICATION OF DIRECTORS AND OFFICERS Our certificate of incorporation provides for indemnification of directors and officers under the circumstances and to the full extent permitted by Delaware law. We have also entered into indemnification agreements with our directors and officers. 72

SHARES ELIGIBLE FOR FUTURE SALE Prior to this offering, there has been no market for our common stock, and we cannot assure you that a significant public market for our common stock will develop or be sustained after this offering. Sales by our existing stockholders of a substantial number of shares of our common stock held by them in the public market could cause the market price of our common stock to fall and could affect our ability to raise capital on terms favorable to us in the future. Upon completion of this offering, we will have outstanding shares of common stock, assuming the underwriters' over-allotment option is not exercised. Of these shares, shares, or shares if the underwriters exercise their over-allotment option in full, of the common stock sold in this offering will be freely tradable without restriction under the Securities Act of 1933 unless purchased by our affiliates as that term is defined in Rule 144 under the Securities Act. The remaining shares of common stock outstanding will be restricted securities under Rule 144 and may in the future be sold without registration under the Securities Act to the extent permitted by Rule 144 or any other applicable exemption under the Securities Act, subject to the restrictions on transfer described in "Description of Securities -- Anti-Takeover Effects of Certificate, Bylaws, Stockholder Rights Plan and Delaware Law -- Contractual Restrictions on Transfer by Certain Stockholders" and the lock-up agreements described below. Our executive officers, directors and certain stockholders have agreed pursuant to lock-up agreements that, with limited exceptions, they will not sell any shares of our common stock for a period of 180 days from the date of this prospectus without the prior written consent of lead underwriter. As a result of these lock-up agreements and the rules under the Securities Act, the restricted shares will be available for sale in the public market, subject in most cases to volume and other restrictions, as follows:

DAYS AFTER THE NUMBER OF SHARES EFFECTIVE DATE ELIGIBLE FOR SALE COMMENT - -------------- ----------------- ------- Upon effectiveness............. Restricted shares not locked up and eligible for sale under Rule 144 90 days........................ Restricted shares not locked up and eligible for sale under Rules 144 and 701 180 days....................... Lock-up released; restricted shares eligible for sale under Rules 144 and 701
Upon expiration of the lock-up period, or to the extent restricted shares are not subject to the lock-up restrictions, the restricted shares will become available for sale in the public market, subject to Rule 144 and Rule 701 of the Securities Act. The shares set forth in the above table do not include 1,635,101 shares of our common stock issuable under options that will be exercisable upon completion of this offering, of which will be eligible for sale after 90 days and of which will be eligible for sale after 180 days. RULE 144 In general, under Rule 144 of the Securities Act as currently in effect, beginning 90 days after the date of this prospectus, a person (or persons whose shares are aggregated, such as an affiliate) who has beneficially owned restricted shares for at least one year, is permitted to 73

sell, within any three-month period, the number of such restricted shares that does not exceed the greater of: - one percent (1%) of the then-outstanding shares of common stock, which will equal approximately shares after giving effect to this offering; or - the average weekly trading volume of our common stock during the four calendar weeks preceding such sale. Sales under Rule 144 are subject to restrictions relating to manner of sale, notice and the availability of current public information about us. RULE 144(k) In addition, under Rule 144(k) of the Securities Act, a person who was not an affiliate of our company at any time within the three months preceding a sale, and who has beneficially owned shares for at least two years, may sell such shares immediately following this offering without having to comply with volume limitations, manner of sale provisions, notice or other requirements of Rule 144. RULE 701 Any employees, directors, officers, consultants and advisors who purchased shares from us in connection with a compensatory stock or option plan or other written agreement may be entitled to rely on the resale provisions of Rule 701. Rule 701 permits resales of such shares 90 days after the effective date of this offering in reliance on Rule 144, without having to comply with the holding period and notice filing requirements of Rule 144 and, in the case of non- affiliates, without having to comply with the public information, volume limitation or notice filing provisions of Rule 144. Following the consummation of this offering, we intend to file a registration statement on Form S-8 covering a total of 3.5 million shares of common stock reserved for issuance under our Incentive Compensation Plan. Shares of our common stock so registered will, subject to vesting provisions, Rule 144 volume limitations applicable to our affiliates and the expiration of any applicable lock-up agreement, be available for sale immediately in the open market. Options covering 1,635,101 shares of our common stock will be exercisable upon completion of this offering. 74

Shares sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus. Any shares sold by the underwriters to securities dealers may be sold at a discount of up to $ per share from the initial public offering price. Any such securities dealers may resell any shares purchased from the underwriters to other brokers for dealers at a discount of up to $ per share from the initial public offering price.

agreement does not apply to any existing employee benefit plans. See "Shares Available for Future Sale" for a discussion of certain transfer restrictions. Prior to this offering, there has been no public market for the shares. The initial public offering price will be negotiated between us and the representative.

In connection with this offering, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in this offering. "Covered" short sales are sales made in an amount not greater than the underwriters' option to purchase additional shares in this offering. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the underwriters' option. "Naked" short sales are any sales in excess of such option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in this offering. Stabilizing transactions consist of various bids for or purchases of common stock made by the underwriters in the open market prior to the completion of this offering. The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representative have repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions. Purchases to cover a short position and stabilizing transactions may have the effect of preventing or retarding a decline in the market price of our stock, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of the common stock. As a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued at any time. These transactions may be effected on , in the over-the-counter market or otherwise. The underwriters do not expect sales to discretionary accounts to exceed five percent of the total number of shares offered. We estimate that our share of the total expenses of this offering, excluding underwriting discounts and commissions, will be approximately $ million, and the selling stockholders estimate that their share will be approximately $ million. The company and the selling stockholders have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933. An affiliate of RBC Dain Rauscher Inc. acted as an initial purchaser in connection with our private placement of 10 5/8% senior notes for which it received customary fees. 76

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (IN THOUSANDS, EXCEPT RATIOS AND PER SHARE INFORMATION) The following unaudited pro forma condensed consolidated financial statements are derived from our historical consolidated financial statements as set forth elsewhere in this prospectus and from the historical combined financial statements of the Spentonbush/Red Star Group included elsewhere in this registration statement with pro forma adjustments based on assumptions we have deemed appropriate. The unaudited pro forma combined statements of operations give effect to offering of shares of common stock and the acquisition of the Spentonbush/Red Star Group tug and tank barge fleet as if the transactions had occurred on January 1, 2001. The Spentonbush/Red Star Group was acquired on May 31, 2001 and accordingly their operating results are included in our historical results from the date of the acquisition. The pro forma balance sheet is presented as if the offering of shares of common stock occurred on March 31, 2002. The transactions and the related adjustments are described in the accompanying notes. In the opinion of management, all adjustments have been made that are necessary to present fairly in accordance with Regulation S-X the pro forma condensed consolidated financial statements. The following unaudited pro forma condensed consolidated financial statements are presented for illustrative purposes only. They do not purport to be indicative of the financial position or results of operations that would actually have occurred if the transactions described had occurred as presented in such statements or that may be obtained in the future. In addition, future results may vary significantly from the results reflected in such statements due to factors described in "Risk Factors" included elsewhere in this registration statement. As discussed in "Use of Proceeds" included elsewhere in this prospectus we intend to use a portion of these proceeds along with cash on hand, cash flow from operations and amounts available under our revolving credit facility, to fund the costs of the construction of our current vessel newbuild program, possible future acquisitions, the retrofit of existing vessels or construction of additional vessels, and for general corporate purposes. The following unaudited pro forma condensed consolidated financial statements should be read in conjunction with the historical consolidated financial statements of the Company and the notes thereto and the combined financial statements of the Spentonbush/Red Star Group and the notes thereto included elsewhere in this registration statement.

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Hornbeck Offshore Services, Inc. and subsidiaries as of December 31, 2001 and 2000, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2001, in conformity with accounting principles generally accepted in the United States.

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS AND SHARES IN THOUSANDS) 1. ORGANIZATION: FORMATION HORNBECK-LEEVAC Marine Services, Inc. (formerly HV Marine Services, Inc.) was renamed Hornbeck Offshore Services, Inc. (hereinafter, the Company), on May 29, 2002. The Company is incorporated in the state of Delaware. The Company wholly owns LEEVAC Marine, LLC, Hornbeck Offshore Services, LLC, HORNBECK-LEEVAC Marine Operators, LLC and Energy Services Puerto Rico, LLC. LEEVAC Marine, LLC and HORNBECK-LEEVAC Marine Operators, LLC were renamed Hornbeck Offshore Transportation, LLC and Hornbeck Offshore Operators, LLC, respectively, on May 29, 2002. All of the subsidiaries were converted from C Corporations to Limited Liability Companies (LLC) in 2001. The accompanying financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. NATURE OF OPERATIONS Hornbeck Offshore Services, LLC (HOS) operates eleven offshore supply vessels to provide support and specialty services to the offshore oil and gas exploration and production industry, primarily in the Gulf of Mexico. Prior to 2000, HOS operated six vessels with one additional vessel being added in each of March 2000, April 2001 and November 2001. Hornbeck Offshore Transportation, LLC (HOT) operates ocean-going tugs and tank barges which provide vessel and barge charters for the transportation of petroleum products. In 2000, HOT operated an average of seven ocean-going tank barges and associated tugs. On May 31, 2001, the Company purchased a fleet of nine ocean-going tugs and nine ocean-going tank barges and the related coastwise transportation businesses from the Spentonbush/Red Star Group, affiliates of Amerada Hess Corporation, for approximately $28,000 in cash. HOT services the north-eastern seaboard of the United States and Puerto Rico. The result of this acquisition has been included since the date of acquisition (see Note 14). Hornbeck Offshore Operators, LLC (HOO) is a service subsidiary that provides administrative and personnel support to the other subsidiaries. Energy Services Puerto Rico, LLC (ESPR) provides administrative and personnel support to employees residing in Puerto Rico. UNAUDITED INTERIM FINANCIAL STATEMENTS The accompanying unaudited consolidated financial statements as of March 31, 2002 and for the three months ended March 31, 2002 and 2001 have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all material adjustments (consisting only of normal and recurring adjustments) necessary to present a fair statement of the Company's financial position and results of operations for the interim periods included herein have been made, and the disclosures contained herein are adequate to make the information presented not misleading. Operating results for the three months ended March 31, 2002 are not necessarily indicative of the results that may be expected for the year ended December 31, 2002. F-14

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: REVENUE RECOGNITION HOS contracts its offshore support vessels to clients under time charters based on a daily rate of hire and recognizes revenue as earned on a daily basis during the contract period of the specific vessel. HOT also contracts its vessels to clients under time charters based on a daily rate of hire. Revenue is recognized on such contracts as earned on a daily basis during the contract period of the specific vessel. Under other contracts, primarily contracts of affreightment, revenue is recognized based on the percentage of days incurred for the voyage to total estimated days applied to total estimated revenues. Voyage related costs are expensed as incurred. Substantially all voyages under these contracts are less than 10 days in length. CASH AND CASH EQUIVALENTS Cash and cash equivalents consist of all highly liquid investments in money market funds and investments available for current use with an initial maturity of three months or less. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are recorded at cost. Depreciation and amortization of equipment and leasehold improvements are computed using the straight-line method based on the estimated useful lives of the related assets. Interest costs incurred during the construction of new vessels are capitalized. Improvements and major repairs that extend the useful life of the related asset are capitalized. Minor repairs and maintenance costs are expensed as incurred. Gains and losses from retirements or other dispositions are recognized currently. The estimated remaining useful lives by classification are as follows:

Tugs........................................................ 14-25 years Tank Barges................................................. 3-18 years Offshore supply vessels..................................... 25 years Machinery and equipment..................................... 5 years
All of the tank barges have estimated economic useful lives based on their classification under the Oil Pollution Act of 1990. DEFERRED CHARGES The Company's tank barges, tugs and offshore supply vessels are required by regulation to be recertified after certain periods of time. The Company defers drydocking costs related to the recertification of the vessels. Deferred drydocking costs are amortized over the length of time in which the improvements made during the recertification is expected to last (generally thirty or sixty months). Financing costs are amortized over the term of the related debt using the interest method. INCOME TAXES Deferred tax assets and liabilities are provided to reflect the future tax consequences of differences between the tax bases of assets and liabilities and their reported amounts on the financial statements. The Company's temporary differences primarily relate to depreciation and deferred drydocking costs. F-15

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Deferred tax assets and liabilities are measured using currently enacted tax rates. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The provision for income taxes includes provisions for both federal and state income taxes. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. CONCENTRATION OF CREDIT RISK Customers are primarily major and independent, domestic and international, oil and oil service companies. The Company's customers are granted credit on a short-term basis and related credit risks are considered minimal. The Company usually does not require collateral. GOODWILL Goodwill reflects the excess of cost over the estimated fair value of the net assets acquired. Goodwill is being amortized on a straight-line basis over its estimated useful life of 25 years. Realization of goodwill is periodically assessed by management based on the expected future profitability and undiscounted future cash flows of acquired entities and their contribution to the overall operations of the Company. Should the review indicate that the carrying value is not recoverable, the excess of the carrying value over the undiscounted cash flow would be recognized as an impairment loss. STOCK-BASED COMPENSATION Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation," established accounting and disclosure requirements using a fair-value-based method of accounting for stock-based employee compensation plans. As provided for under SFAS No. 123, the Company accounts for stock-based compensation using the intrinsic value method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees." Compensation cost for stock options, if any, is measured as the excess of the quoted market price of the Company's stock at the date of grant over the amount an employee must pay to acquire the stock. IMPAIRMENT OF LONG-LIVED ASSETS AND INTANGIBLE ASSETS When events or circumstances indicate that the carrying amount of long-lived assets to be held and used or intangible assets might not be recoverable, the expected future undiscounted cash flows from the assets is estimated and compared with the carrying amount of the assets. If the sum of the estimated undiscounted cash flows is less than the carrying amount of the assets, an impairment loss is recorded. The impairment loss is measured by comparing the fair value of the assets with their carrying amounts. Fair value is determined based on discounted cash flow or appraised values, as appropriate. Long-lived assets that are held for disposal are reported at the lower of the assets' carrying amount or fair value less costs related to the assets' disposition. F-16

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) EARNINGS PER SHARE Basic net income (loss) per share of common stock was calculated by dividing net income (loss) applicable to common stock by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share of common stock was calculated by dividing net income (loss) applicable to common stock by the weighted average number of common shares outstanding during the year plus the effect of dilutive stock options and warrants. Dilutive stock options and warrants, utilizing the treasury stock method, represented 215, 3,108 and 269 for the year ended December 31, 2001 and the three months ended March 31, 2001 and 2002. Options and warrants that were excluded from the computation of diluted net income (loss) per share of common stock, become their effect was antidilutive, was 12,047, 12,262 and 11,905 for the years ended December 31, 1999, 2000 and 2001, respectively. RECENT ACCOUNTING PRONOUNCEMENTS In early 1998, the American Institute of Certified Public Accountants (AICPA) issued Statement of Position (SOP) 98-5, "Reporting on the Costs of Start-Up Activities." The SOP is effective for fiscal years beginning after December 15, 1998 and requires costs of start-up activities and organization costs to be expensed as incurred. The unamortized costs were written off and reflected as a cumulative effect of a change in accounting principle during 1999. Effective January 1, 2001, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities," which establishes accounting and reporting standards that every derivative instrument be recorded in the balance sheet as either an asset or liability measured at its fair value. The adoption did not have an impact on the Company's financial position as it has not entered into any derivative instruments. In July 2001, the Financial Accounting Standards Board (FASB) issued Financial Accounting Standards Statement (SFAS) No. 141, "Business Combinations" and Financial Accounting Standards Statement (SFAS) No. 142, "Goodwill and Other Intangible Assets." SFAS 141 eliminates the pooling-of-interests method of accounting for business combinations except for qualifying business combinations that were initiated prior to July 1, 2001. The purchase method of accounting is required to be used for all business combinations initiated after June 30, 2001. SFAS 141 also requires separate recognition of intangible assets that meet certain criteria. Under SFAS 142, goodwill and indefinite-lived intangible assets are no longer amortized but are reviewed for impairment annually, or more frequently if circumstances indicate potential impairment. Separable intangible assets that are not deemed to have an indefinite life will continue to be amortized over their useful lives. For goodwill and indefinite-lived intangible assets acquired prior to July 1, 2001, goodwill will continue to be amortized through 2001 at which time amortization will cease and a transitional goodwill impairment test will be performed. Any impairment charges resulting from the initial application of the new rules will be classified as a cumulative change in accounting principle. The initial transition evaluation was completed by June 30, 2002 which is within the six month transition period allowed by the new standard. The Company's goodwill balances were determined not to be impaired. Goodwill amortization for each of the years ended December 31, 1999, 2000 and 2001 was $126. F-17

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) The following table presents the Company's net income as reported in the Company's unaudited consolidated financial statements compared to that which would have been reported had the Company adopted SFAS 142 as of January 1, 2001.

THREE MONTHS ENDED MARCH 31, ------------------ 2001 2002 ---- ---- Net income, as reported..................................... $1,758 $3,489 Amortization of goodwill.................................... 32 -- ------ ------ Net income, as adjusted..................................... $1,790 $3,489 ====== ======
There was no per share effect from the adoption of SFAS 142. In July 2001, the FASB issued Statement of Financial Accounting Standards (SFAS) No. 143, "Accounting for Asset Retirement Obligations," which requires recording the fair value of a liability for an asset retirement obligation in the period incurred. SFAS 143 is effective for fiscal years beginning after June 15, 2002, with earlier application permitted. Upon adoption of SFAS 143, the Company will be required to use a cumulative effect approach to recognize transition amounts for any existing retirement obligation liabilities, asset retirement costs and accumulated depreciation. The Company does not have any asset retirement obligations; therefore, adoption of this statement does not have effect on the financial statements. In August 2001, the FASB issued Statement of Financial Accounting Standards (SFAS) No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" (SFAS 144), which supersedes FASB Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of". SFAS 144 also supersedes certain aspects of APB 30, "Reporting the Results of Operations-Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions", with regard to reporting the effects of a disposal of a segment of a business and will require expected future operating losses from discontinued operations to be reported in discontinued operations in the period incurred rather than as of the measurement date as presently required by APB 30. The provisions of SFAS 144 are required to be applied for fiscal years beginning after December 15, 2001 and interim periods within those fiscal years. The adoption of this statement is not expected to have any effect on the Company's financial statements. In April 2002, the FASB issued Statement of Financial Accounting Standards (SFAS) No. 145, "Rescission of FASB Statement No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections." SFAS 145 requires that gains or losses recorded from the extinguishment of debt that do not meet the criteria of APB Opinion No. 30 should not be presented as extraordinary items. This statement is effective for fiscal years beginning after May 15, 2002 as it relates to the reissued FASB Statement No. 4, with earlier application permitted. Any gain or loss on extinguishment of debt that was classified as an extraordinary item in prior periods presented that does not meet the criteria in APB 30 for classification as an extraordinary item should be reclassified. The Company has elected not to early adopt. Accordingly, the losses on extinguishment of debt incurred in 2001 remains classified as an extraordinary item in the accompanying statements of operations. F-18

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 3. DEFINED CONTRIBUTION PLAN: The Company was a participating employer in the Cari Investment Company 401(k) Plan, a defined contribution plan with a cash or deferred compensation arrangement pursuant to Section 401(k) of the Internal Revenue Code. The Company established a simple employer plan on March 1, 2001 which covers employees who are at least twenty-one years of age and have completed one year of service are eligible for participation. Participants may elect to defer up to 20 percent of their compensation, subject to certain statutorily established limits. The Company may elect to make annual matching and/or profit sharing contributions to the plan. During the years ended December 31, 1999, 2000 and 2001 the Company made contributions of $6, $6 and $75, respectively. 4. PROPERTY, PLANT AND EQUIPMENT: Property, plant and equipment consisted of the following:

DECEMBER 31, ------------------ MARCH 31, 2000 2001 2002 ---- ---- --------- (UNAUDITED) Tugs............................................ $ 9,467 $ 28,846 $ 28,861 Tank barges..................................... 14,614 26,504 26,504 Offshore supply vessels......................... 69,744 102,932 102,703 Construction in progress........................ 12,294 36,402 48,317 Machinery and equipment......................... 818 581 658 Less: Accumulated depreciation.................. (8,002) (14,484) (16,636) ------- -------- -------- $98,935 $180,781 $190,407 ======= ======== ========
Interest expense of $815, $365, $3,075 and $1,003 was capitalized for the years ended December 31, 1999, 2000 and 2001, and the three months ended March 31, respectively. 5. INVESTMENT IN UNCONSOLIDATED ENTITY: In years prior to 2000 and for over ten months in 2000 the Company had a 60 percent limited partner interest in a partnership. The remaining 40 percent was owned by an entity in which the Company's former Chairman of the Board and Chief Executive Officer had a minority interest. The partnership's only asset was a tank barge which was leased by the Company on a short-term basis. The Company accounted for this investment using the cost-method of accounting because it did not exert significant influence over the operations of the partnership. Monthly lease payments were charged to expense, and partnership profit distributions were netted against the lease expense. During the years ended December 31, 1999, 2000 and 2001 HOT's lease expense, net of distributions, related to this partnership was approximately $105, $106 and $0, respectively. As part of its $35,000 private equity offering in November 2000, the Company issued approximately 340 shares of common stock at a per share price of $2.65 for an aggregate of $900 in exchange for the remaining 40 percent of the partnership. The price represented 40 percent of the value of the tank barge based on an independent appraisal. As a result the barge was recorded as an asset in the Company's consolidated property, plant and equipment. F-19

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 6. LONG-TERM DEBT: On June 5, 1998, the Company entered into a $43,000 line of credit agreement with two banks (Facility A) and $15,000 and $20,000 line of credit agreements (Facility B and C, respectively) with two venture capital companies. These "Credit Agreements" were used to refinance existing indebtedness and partially finance the construction of offshore supply vessels (see Note 9). Facilities A and B converted to term loans upon the completed construction of certain offshore supply vessels. In connection with Facility C, the Company issued detachable warrants to purchase 11,905 shares of common stock. The warrants were assigned an estimated market value of $500. The warrants for the purchase of 10,500 shares of common stock were exercisable with an exercise price of $1.68 per share. The remaining warrants became exercisable only on the occurrence of an event of default under Facility C, the Company filing for bankruptcy or if the indebtedness under Facility C was not discharged in full by June 5, 2003. All of the warrants issued in connection with establishment of Facility C provided the holders with a put option whereby the holders had the right, if the Company's stock was not publicly traded by June 5, 2003 to require the Company to repurchase the warrants at their fair market value. According to EITF Issue 88-9, Accounting for Put Warrants, issued by the Emerging Issues Task Force and supplemented by EITF Issue 00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company's own Stock, a company whose stock is publicly traded is required to account for warrants that contain put options as a liability. As previously discussed, the Company assigned a market value of $500 to the warrants at issuance based on the relative fair value of the Facility C debt and the warrants. The $500 was allocated to debt with all subsequent changes to the fair market value of the warrants for each period presented being recorded as a noncash adjustment to interest expense. The Company repurchased and terminated all of the warrants for $14,500 in October 2001. The repurchase of the warrants was funded by a private placement of the Company's common stock for gross proceeds of $14,650. The remaining funds were used for payment of expenses incurred in the offering. On March 5, 1999, the Facility A credit agreement was amended by the Company with the two banks by which it was then maintained. The commitment was increased from $43,000 to $49,400 along with an extension of the outside date for conversion of construction loans to term loans. The conversion date occurred upon the completed construction and delivery of an offshore supply vessel in March 2000. In July and November 2000, the Company entered into two new credit facilities (collectively, Facility D) totaling $41,400 with a new lender. Of the proceeds, $15,000 was used to repay Facility B in full. The remaining amounts were used to pay the construction costs of additional offshore supply vessels. At December 31, 2000, Facility D was collateralized by two existing vessels and four vessels under construction. In November 2000, Facility A credit agreement was amended by the Company. The Commitment was increased from $49,400 to $69,000. These additional funds were used to build additional vessels. On July 24, 2001, the Company issued $175,000 in principal amount of 10 5/8% senior notes. The Company realized net proceeds of approximately $165,000, a substantial portion of which was used to repay and fully extinguish all of the then existing credit facilities. The senior notes mature on August 1, 2008 and require semi-annual interest payments at an annual rate of 10 5/8 percent on February 1 and August 1 of each year until maturity, with the first payment due on February 1, 2002. The effective interest rate on the senior notes is 11.18 percent. No principal F-20

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) payments are due until maturity. The senior notes are unsecured senior obligations and rank equally in right of payment with other existing and future senior indebtedness and senior in right of payment to any subordinated indebtedness incurred by the Company in the future. The senior notes are guaranteed by all of the Company's subsidiaries. The Company may, at its option, redeem all or part of the senior notes from time to time at specified redemption prices and subject to certain conditions required by the Indenture. The Company is permitted under the terms of the Indenture to incur additional indebtedness in the future, provided that certain financial conditions set forth in the Indenture are satisfied by the Company. As of December 31, 2001, the Company was permitted to incur a minimum of $25,000 of additional indebtedness. In connection with the issuance of the senior notes, the Company wrote-off deferred financing costs related to previous credit facilities. The write-off in the amount of $1,964 (net of tax of $1,065) has been presented as an extraordinary item in the accompanying statements of operations. The Company completed an Exchange Offer on January 18, 2002, whereby the 10 5/8% Series A Senior Notes, due 2008, were exchanged for 10 5/8% Series B Senior Notes with the same terms, the offering of which was publicly registered. Effective December 31, 2001, the Company entered into a new senior secured revolving line of credit (the Revolver) for $50,000 with one of its former lenders. Pursuant to the terms of the Revolver, the Company's borrowings under this facility will initially be limited to $25,000 unless we have obtained the lender's concurrence to borrow in excess of $25,000. Pursuant to the indenture governing the senior notes, unless the Company meets a specified consolidated interest coverage ratio test, the level of permitted borrowings under this facility initially will be limited to $25,000 plus 15 percent of the increase in the Company's consolidated net tangible assets over the consolidated net tangible assets as of March 31, 2001 determined on a pro forma basis to reflect the Spentonbush/Red Star Group acquisition. Unused commitment fees are payable quarterly at the annual rate of three-eighths of one percent on the revolving line of credit. F-21

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) As of the dates indicated, the Company had the following outstanding long-term debt:

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 7. SHAREHOLDERS' EQUITY Preferred Stock The Company's charter authorizes 5,000 shares of Preferred Stock. The Board of Directors has the authority to issue Preferred Stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series or the designation of such series, without further vote or action by the Company's shareholders. Shareholder Rights Plan The Company's Board of Directors approved the form of a stockholder rights plan on July 18, 2002 in anticipation of declaring a dividend of one right for each outstanding share of common stock to stockholders of record upon completion of the Company's initial public offering of its common stock. Once a dividend of rights is declared, the rights will only become exercisable, and transferable apart from the Company's common stock, 10 business days following a public announcement that a person or group has acquired beneficial ownership of, or has commenced a tender or exchange offer for, 15% or more of the Company's common stock. The rights will have anti-takeover effects. The rights will cause substantial dilution to a person or group who attempts to acquire the Company without the approval of the Board of Directors. As a result, the overall effect of the rights may be to render more difficult or discourage any attempt to acquire the Company even if such acquisition may be favorable to the interests of the Company's stockholders. Because the Board of Directors can redeem the rights or approve certain offers, the rights should not interfere with any merger or other business combination approved by the Company's Board of Directors. 8. STOCK OPTION PLANS: SFAS No. 123, "Accounting for Stock-Based Compensation," established financial accounting and reporting standards for stock-based compensation plans. The Company's plan includes all arrangements by which employees and directors receive shares of stock or other equity instruments of the Company, or the Company incurs liabilities to employees or directors in amounts based on the price of the stock. SFAS No. 123 defines a fair-value-based method of accounting for stock-based compensation. However, SFAS No. 123 also allows an entity to continue to measure stock-based compensation cost using the intrinsic value method of APB Opinion No. 25, "Accounting for Stock Issued to Employees." Entities electing to retain the accounting prescribed in APB No. 25 must make pro forma disclosures of net income assuming dilution as if the fair-value-based method of accounting defined in SFAS No. 123 had been applied. The Company retained the provisions of APB No. 25 for expense recognition purposes. Under APB No. 25, where the exercise price of the Company's stock options equals the market price of the underlying stock on the date of grant, no compensation expense in recognized. The Company established an incentive stock option plan which provides that options for a maximum of 3,500 shares of common stock that may be granted by the Company. The purchase price of the stock subject to each option is determined by the Board of Directors of the Company and cannot be less than the fair market value of the stock at the date of grant. No options have been exercised to date. All options granted expire 5-10 years after date of grant, have an exercise price equal to or greater than the estimated market price of the Company's stock at the date of grant and vest over a 2 to 4 year period.

HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) The following summarizes the option activity in the plans during 1999, 2000 and 2001:

1999 2000 2001 ------------------- ------------------- ------------------- WEIGHTED WEIGHTED WEIGHTED AVERAGE AVERAGE AVERAGE PRICE PRICE PRICE OPTIONS PER SHARE OPTIONS PER SHARE OPTIONS PER SHARE ------- --------- ------- --------- ------- --------- Outstanding, beginning of year........................ 53 $1.85 150 $1.85 386 $1.97 Granted............................................. 97 1.85 236 2.04 1,420 2.65 Cancelled........................................... -- -- -- -- (66) 2.36 --- ----- --- ----- ----- ----- Outstanding, end of year.............................. 150 $1.85 386 $1.97 1,740 $2.51 === ===== === ===== ===== ===== Exercisable, end of year.............................. 76 196 568 === === ===== Weighted average fair value of options granted during the year............................................ $ .38 $ .52 $ .74 ===== ===== =====
The weighted average remaining contractual life for the options at December 31, 2001 was 5 years. The fair value of the options granted under the Company's stock option plan during each of the three years ended December 31, 2001 and the three months ended March 31, 2002, was estimated using the Black-Scholes Pricing Model using the minimum value method whereby volatility is not considered. For 1999, a risk-free interest rate of 5.79%; dividend yield of zero; and a weighted average expected life of the options of 7 years. For 2000, a risk-free interest rate of 6.20%; dividend yield of zero; and a weighted average expected life of the options of 6 years. For 2001, a risk-free interest rate of 4.88%; dividend yield of zero; and a weighted average expected life of the options of 6 years. Had compensation cost for the Company's stock options been determined based on the fair value at the grant date consistent with the method under SFAS No. 123, the Company's basic and diluted net income (loss) per share of common stock for the years ended December 31, 1999, 2000 and 2001 would have been as indicated below:

REPORT OF INDEPENDENT AUDITORS To the Board of Directors and Stockholders of Spentonbush/Red Star Group: We have audited the accompanying combined balance sheets of Spentonbush/Red Star Group (as discussed in Note 1) as of December 31, 2000 and 1999, and the related combined statements of income and retained earnings and cash flows for each of the three years in the period ended December 31, 2000. These financial statements are the responsibility of the Group's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Spentonbush/Red Star Group as of December 31, 2000 and 1999, and the results of their income and their cash flows for each of the three years in the period ended December 31, 2000, in conformity with accounting principles generally accepted in the United States.

(New York) Hygrade Operators, Inc. (New York) Red Star Towing & Transportation Company (New York) Sheridan Towing Co., Inc. (Delaware) Each is an indirect wholly owned subsidiary of Amerada Hess Corporation ("Parent") and is included in its Parent's consolidated financial statements. The Group is an owner and operator of vessels engaged in tug and tank barge operations. A significant portion of the Group's business is transacted with the Parent and its affiliates (see Note 3). PRINCIPLES OF COMBINATION The combined financial statements include the accounts of the Group. All intergroup transactions have been eliminated. REVENUE RECOGNITION Revenues and related voyage expenses are recognized on an accrual basis. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are recorded at cost. Depreciation of property, plant and equipment is computed using the straight-line method based on the estimated useful lives of the related assets. Improvements that extend the useful life of the related asset are capitalized; all other expenditures for maintenance and repairs, excluding drydock, are expensed as incurred. Gains and losses from retirements or other dispositions are recognized as incurred. F-37

SPENTONBUSH/RED STAR GROUP NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED) DRYDOCK RESERVES The Group's vessels are required to be recertified by the United States Coast Guard after certain periods of time. The Group maintains a drydock reserve to accrue for estimated drydocking costs over the operating period preceding each scheduled drydocking. Drydocking expenses are recognized as the reserves are accrued and the reserves are included in accrued liabilities. INCOME TAXES The Group is included in the consolidated federal income tax return of the Parent. In 1998, 1999 and 2000, the Parent allocated federal income tax expense at a rate of 35%. This allocation is comparable to the amount that would be provided for income taxes if the provision was determined on a stand-alone basis. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using currently enacted tax rates. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. 2. INCOME TAXES The components of income tax expense (benefit) were as follows:

1998 1999 2000 ---- ---- ---- Current.................................................. $2,026 $1,303 $3,935 Deferred................................................. (114) 620 (530) ------ ------ ------ Total.......................................... $1,912 $1,923 $3,405 ====== ====== ======
Total income tax expense for 2000, 1999 and 1998 was different from the amount computed by applying the statutory federal income tax rate due primarily to state income taxes and certain non-deductible travel and entertainment expenses. The tax effect of significant temporary differences that give rise to the net deferred tax assets are differences in the basis of property, plant and equipment and drydock reserves. The current taxes payable of the Group which are owed to its Parent are $1,225 and $3,893 at December 31, 1999 and 2000, respectively. F-38

YEAR ENDED --------------------------- 1998 1999 2000 ---- ---- ---- Marine transportation -- affiliates................... $27,165 $24,962 $34,120 Operating expenses.................................... 235 747 702 General and administrative expenses................... 1,001 998 1,874
DECEMBER 31, ----------------- 1999 2000 ---- ---- Accounts receivable -- affiliates........................... $21,149 $24,479 Current taxes payable....................................... (1,225) (3,893)
Effective January 1, 2000, the Group entered into Service Level Agreements with its Parent. Under these agreements the Parent provides information systems services, human resources, risk management and other administrative related functions to the Group. The fee charged for these services is based upon estimated level of time expended for human resources, risk management and other administrative functions plus volume-related charges for information systems activities. Prior to January 1, 2000, the Parent allocated an amount to the Group for the services provided. The fees allocated for these services are reported as selling, general and administrative expenses in the table above and in the accompanying statement of income and retained earnings. During the years ended December 31, 1998, 1999 and 2000, affiliates of the Group provided certain vessel operating expenses which included fuel costs and insurance related to vessel operations. Advances to parent represent non-interest bearing advances of cash to the Parent. Accordingly, advances are recorded as a component of stockholder's equity in the accompanying combined balance sheet. 4. DRYDOCK RESERVES Drydock reserves are in accrued liabilities and the analysis of changes in these reserves as of the periods indicated are as follows:
DECEMBER 31, --------------------------- 1998 1999 2000 ---- ---- ---- Drydock reserve, beginning of period.................. $ 3,647 $ 3,913 $ 2,588 Drydock expense....................................... 1,880 2,095 2,927 Payments on completed drydock costs................... (1,614) (3,420) (1,407) ------- ------- ------- Drydock reserve, end of period........................ $ 3,913 $ 2,588 $ 4,108 ======= ======= =======
5. CONTINGENCIES The Group is subject to contingent liabilities with respect to existing or potential claims, lawsuits and other proceedings. The Group considers these routine and incidental to its business F-39

SPENTONBUSH/RED STAR GROUP NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED) and not material to its financial position or results of operations. The Group accrues liabilities when the future costs are probable and estimable. 6. SUBSEQUENT EVENT On May 31, 2001, the Group sold nine ocean-going tugs and nine ocean-going tank barges and the related coastwise transportation business to Hornbeck Offshore Services, Inc. (Hornbeck Offshore) for approximately $28 million in cash. In connection with the transaction, Amerada Hess then entered into a contract of affreightment with Hornbeck Offshore, whereby Hornbeck Offshore will provide marine logistics and coastwise transportation in the northeastern United States to Amerada Hess. The Group's remaining ocean-going tug and ocean-going tank barge will continue to provide transportation services to Amerada Hess, primarily in the Caribbean market. F-40

INDEMNIFICATION OF DIRECTORS AND OFFICERS The General Corporation Law of Delaware, under which we are incorporated, authorizes the indemnification of directors and officers under the circumstances described below. To the extent one of our present or former directors or officers is successful on the merits or otherwise in defense of any action, suit or proceeding described below, the General Corporation Law of Delaware requires that such person be indemnified against expenses, including attorneys' fees, actually and reasonably incurred by such person in connection with such action, suit or proceeding. Article VIII of our Certificate of Incorporation requires indemnification of our directors and officers to the extent permitted by law. Section 6.10 of our bylaws provides for, and sets forth the procedures for obtaining, such indemnification. These provisions may be sufficiently broad to indemnify such persons for liabilities under the Securities Act of 1933. In addition, we maintain insurance which insures our directors and officers against certain liabilities. The General Corporation Law of Delaware gives us the power to indemnify each of our officers and directors against expenses, including attorneys' fees, and judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any action, suit or proceeding by reason of such person being or having been one of our directors, officers, employees or agents, or of any other corporation, partnership, joint venture, trust or other enterprise at our request. To be entitled to such indemnification, such person must have acted in good faith and in a manner he reasonably believed to be in or not opposed to our best interest and, if a criminal proceeding, had no reasonable cause to believe that the conduct was unlawful. The General Corporation Law of Delaware also gives us the power to indemnify each of our officers and directors against expenses, including attorneys' fees, actually and reasonably incurred by such person in connection with the defense or settlement of any action or suit by or in the right of us to procure a judgment in our favor by reason of such person being or having been one of our directors, officers, employees or agents, or of any other corporation, partnership, joint venture, trust or other enterprise at our request, except that we may not indemnify such person with respect to any claim, issue or matter as to which such person was adjudged to be liable to us in the absence of a determination by the court that, despite the adjudication of liability, such person is fairly and reasonably entitled to indemnity. To be entitled II-1

to such indemnification, such person must have acted in good faith and in a manner he reasonably believed to be in or not opposed to our best interest. We have also entered into indemnification agreements with our directors and officers. These agreements provide rights that are consistent with but more detailed than those provided under Delaware Law and our bylaws. The indemnification agreements are not intended to deny or otherwise limit third-party derivative suits against us or our directors or officers, but if a director or officer is entitled to indemnity or contribution under the indemnification agreement, the financial burden of the third-party suit would be borne by us, and we would not benefit from derivative recoveries against the director or officer. Such recoveries would accrue to the benefit of us but would be offset by our obligations to the director or officer under the indemnification agreement. ITEM 15.

On January 18, 2002, all of the Series A notes were exchanged for a like principal amount of our 10 5/8% Series B notes due 2008, which are identical in all material respects to the form and terms of the Series A notes, except that the offering of the Series B notes was registered under the Securities Act. We did not receive any proceeds from the exchange offer. ITEM 16. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES (a) Exhibits:

UNDERTAKINGS The undersigned registrant hereby undertakes to provide to the underwriter at the closing specified in the underwriting agreements, certificates in such denominations and registered in such names as required by the underwriter to permit prompt delivery to each purchaser. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described in Item 14 above, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities II-5

(other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. The undersigned registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430(A) and contained in a form of prospectus filed by the Company pursuant to Rule 424(b)(1) or (4) of 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective. (2) For purposes of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. II-6

SIGNATURES Pursuant to the requirements of the Securities Act of 1933, as amended, the registrant has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Mandeville, the State of Louisiana, on July 19, 2002.

EXHIBIT 3.5 CERTIFICATE OF AMENDMENT TO CERTIFICATE OF INCORPORATION HORNBECK-LEEVAC MARINE SERVICES, INC. Pursuant to section 242 of Title 8 of the Delaware General Corporation Law, HORNBECK-LEEVAC Marine Services, Inc., a corporation organized and existing under and by virtue of the General Corporation Law of the State of Delaware (the "Corporation"), does hereby certify: FIRST: The Certificate of Incorporation of the Corporation is hereby amended so that Article One reads in its entirety as follows: ARTICLE ONE The name of the Corporation is Hornbeck Offshore Services, Inc. SECOND: The Certificate of Incorporation of the Corporation is hereby amended so that Article Twelve reads in its entirety as follows: ARTICLE TWELVE Section 1. Purpose and effectiveness. The purpose of this Article Twelve is to limit ownership and control of shares of any class of capital stock of the Corporation by Aliens in order to permit the Corporation and/or its Subsidiaries or Controlled Persons to conduct their business as U.S. Maritime Companies. Section 2. Restriction on transfers. Any transfer, or attempted or purported transfer, of any shares of any class of capital stock issued by the Corporation or any interest therein or right thereof, which would result in the ownership or control by one or more Aliens of an aggregate percentage of the shares of any class of capital stock of the Corporation or of any interest therein or right thereof in excess of the Permitted Percentage will, until such excess no longer exists, be void and will be ineffective as against the Corporation and the Corporation will not recognize, to the extent of such excess, the purported transferee as a stockholder of the Corporation for any purpose other than the transfer of such excess to a person who is not an Alien; provided, however, that such shares, to the extent of such excess, may nevertheless be deemed to be Alien owned shares for the purposes of this Article Twelve. The Board of Directors is hereby authorized to adopt such bylaws and resolutions, and to effect any and all other measures reasonably necessary or desirable (consistent with applicable law and the provisions of the Certificate of Incorporation) to fulfill the purpose and implement the provisions of this Article Twelve, including without limitation, obtaining, as a condition precedent to the transfer of shares on the records of the Corporation, representations and other

proof as to the identity of existing or prospective stockholders and persons on whose behalf shares of any class of capital stock of the Corporation or any interest therein or right thereof are or are to be held or establishing and maintaining a dual stock certificate system under which different forms of stock certificates, representing outstanding shares of Common Stock or Preferred Stock of the Corporation, are issued to the holders of record of the shares represented thereby to indicate whether or not such shares or any interest therein or right thereof is owned or controlled by an Alien. Section 3. Suspension of voting, dividend and distribution rights with respect to alien owned stock. No shares of the outstanding capital stock of the Corporation or any class thereof held by or for the benefit of any Alien determined to be in excess of the Permitted Percentage in accordance with this Section 3 of this Article Twelve (such shares referred to herein as the "Excess Shares") will, until such excess no longer exists, be entitled to receive or accrue any rights with respect to any dividends or other distributions of assets declared payable or paid to the holders of such capital stock during such period. Furthermore, no Excess Shares will be entitled to vote with respect to any matter submitted to stockholders of the Corporation so long as such excess exists. If Excess Shares exist, the shares deemed included in such Excess Shares for purposes of this Section 3 of this Article Twelve will be those Alien owned shares that the Board of Directors determines became so owned most recently. Section 4. Redemption of Shares. The Corporation, by action of the Board of Directors, shall have the power, but not the obligation, to redeem Excess Shares subject to the following terms and conditions: (1) the per share redemption price to be paid for the Excess Shares shall be the sum of (A) the Fair Market Value of such shares of capital stock plus (B) an amount equal to the amount of any dividend or distribution declared in respect of such shares prior to the date on which such shares are called for redemption and which amount has been withheld by the Corporation pursuant to Section 3 of this Article Twelve (the "Redemption Price"); (2) the Redemption Price shall be paid either in cash (by bank or cashier's check) or by the issuance of Redemption Notes, as determined by the Board of Directors, in its discretion; (3) the Excess Shares to be redeemed shall be selected in the same manner as provided in Section 3 above and shall not exceed the number necessary to reduce the percentage of shares of capital stock of the Corporation or any class thereof owned by Aliens, in the aggregate, to the Permitted Percentage; provided that the Corporation may adjust upward to the nearest whole share the number of shares to be redeemed so as not to be required to redeem or issue fractional shares; (4) written notice of the date of redemption (the "Redemption Date") together with a letter of transmittal to accompany certificates evidencing shares of stock which are 2

surrendered for redemption shall be given by first class mail, postage prepaid, mailed not less than 10 days prior to the Redemption Date to each holder of record of the selected shares to be redeemed, at such holder's last known address as the same appears on the stock register of the Corporation (unless such notice is waived in writing by any such holders) (the "Redemption Notice"); (5) the Redemption Date (for purposes of determining right, title and interest in and to shares of capital stock being selected for redemption) shall be the later of (A) the date specified as the redemption date in the Redemption Notice given to record holders (which date shall not be earlier than the date such notice is given) or (B) the date on which the funds or Redemption Notes necessary to effect the redemption have been irrevocably deposited in trust for the benefit of such record holders; (6) each Redemption Notice shall specify (A) the Redemption Date, as determined pursuant to clause (5) of this Section 4, (B) the number and class of shares of capital stock to be redeemed from such holder (and the certificate number(s) evidencing such shares), (C) the Redemption Price and the manner of payment thereof, (D) the place where certificates for such shares are to be surrendered for cancellation against the simultaneous payment of the Redemption Price, (E) any instructions as to the endorsement or assignment for transfer of such certificates and the completion of the accompanying letter of transmittal; and (F) the fact that all right, title and interest in respect of the shares so selected for redemption (including, without limitation, voting and dividend rights) shall cease and terminate on the Redemption Date, except for the right to receive the Redemption Price; (7) from and after the Redemption Date, all right, title and interest in respect of the shares selected for redemption (including, without limitation, voting and dividend rights) shall cease and terminate, such shares shall no longer be deemed to be outstanding (and may either be retired or held by the Corporation as treasury stock) and the owners of such shares shall thereafter be entitled only to receive the Redemption Price; and (8) upon surrender of the certificates for any shares so redeemed in accordance with the requirements of the Redemption Notice and accompanying letter of transmittal (and otherwise in proper form for transfer as specified in the Redemption Notice), the owner of such shares shall be entitled to payment of the Redemption Price. In case fewer than all the shares represented by any such certificate are redeemed, a new certificate (or certificates) shall be issued representing the shares not redeemed without cost to the holder thereof. Section 5. Severability. Each provision of this Article Twelve is intended to be severable from every other provision. If any one or more of the provisions contained in this Article Twelve is held to be invalid, illegal or unenforceable, the validity, legality or enforceability of any other provision of this Article Twelve shall not be affected, and this Article Twelve shall be construed as if the provisions held to be invalid, illegal or unenforceable had never been contained therein. 3

The number may be decreased below four (4) or increased above nine (9) only by (a) the vote of holders of at least eighty percent (80%) of the shares entitled to vote thereon, or (b) the unanimous vote of the Board of Directors. No decrease in number of directors shall shorten the term of any incumbent director. Directors need not be residents of Delaware but shall be stockholders of the Corporation. Except as otherwise provided in Section 4.3 of these Bylaws, the Board of Directors shall be divided into three classes, each class to be as nearly equal in number as possible. The terms of office of directors of the first class are to expire at the first annual meeting of stockholders after their election or appointment, that of the second class is to expire at the second annual meeting after their election or appointment, and that of the third class is to expire at the third annual meeting after their election or appointment.

Any such election shall be conducted in accordance with Section 3.10 of these Bylaws. Each person elected a director shall hold office until his successor is duly elected and qualified or until his earlier resignation or removal in accordance with Section 4.2 of these Bylaws. To alter or repeal this classified board provision, the affirmative vote of the holders of at least eighty percent (80%) of the shares entitled to vote thereon is required. Section 4.2 is hereby amended to read in its entirety as follows: Section 4.2. Removal. Any director or the entire Board of Directors may be removed from office, at any time, but only for cause, at any meeting of stockholders by the affirmative vote of at least 80% of the shares of the stockholders entitled to vote at such meeting, if notice of the intention to act upon such matter shall have been given in the notice calling such meeting. If the notice calling such meeting shall have been so provided, the vacancy caused by such removal may be filled at such meeting by the affirmative vote of at least 80% of the shares of the stockholders present in person or by proxy and entitled to vote.

"Cause" is defined to include only: Conviction of a felony; declaration of unsound mind by order of court; gross dereliction of duty; commission of an action involving moral turpitude; or commission of an action which constitutes intentional misconduct or a knowing violation of law if such action in either event results both in an improper substantial personal benefit and a material injury to the Corporation. Section 4.3 is hereby amended to read in its entirety as follows: Section 4.3. Vacancies. Vacancies and newly created directorships resulting from any increase in the authorized number of directors may be filled by a majority of the directors then in office, although less than a quorum, or by a sole remaining director. When one or more directors shall die, resign, or be removed from the board, a majority of the directors then in office, including, if applicable, those who have so resigned effective at a future date, shall have power to fill such vacancy or vacancies, the vote thereon to take effect when such resignation or resignations shall become effective, and each director so chosen shall hold office as provided in this section in the filling of other vacancies. A director elected to fill a vacancy shall be elected for the unexpired term of his predecessor in office.

(c) The Company may withdraw any registration statement and abandon any proposed offering initiated by the Company without the consent of any Holder of Registrable Securities, notwithstanding the request of any such Holder to participate therein in accordance with this provision, if the Company determines in its sole discretion that such action is in the best interests of the Company and its stockholders (for this purpose, the interest of the Holders in effecting the registration and offering shall not be considered). 3

Following receipt of such request, the Company shall, no later than 10 Business Days after receipt of such request, notify such Specified Holder of its election to either (1) file, at the Company's expense, the registration statement covering such shares for sale by such Specified Holder; provided, that the Company may, if necessary, delay the filing of any registration statement relating to any such Special Demand Registration for such reasonable period of time, not to exceed 90 days, as is necessary to prepare the financial statements of the Company for the fiscal period most recently ended prior to such written request, or (2) if the Company is not at such time registered under the Exchange Act, purchase the number of shares requested to be registered from such Specified Holder at a price per share equal to the Fair Market Value for shares of Common Stock. In the event the Company elects to exercise its rights under (2) above, such Specified Holder shall not be required to sell such Registrable Securities to the Company, but because the Company offers to purchase such Registrable Securities, its obligation to register such Registrable Securities on demand under this Section 2.2(a)(ii) shall have been satisfied. Within 10 Business Days after the Company provides its notice of election to such Specified Holder, the Company will serve written notice (the "Special Demand Notice") of such registration request to all Holders of Registrable Securities and the Company will include in such registration or Company purchase of shares, together with the shares of the Specified Holder, all such Registrable Securities with respect to which the Company has received written requests for inclusion therein within 10 Business Days after the receipt by the applicable Holder of the Special Demand Notice. If a Holder of Registrable Securities shall fail to request inclusion in such Special Demand Registration or Company purchase of shares, and such Special Demand Registration shall not 4

become effective under the 1933 Act, or the Company does not purchase part of all of the shares of Registrable Securities provided for because one or more Holders chose not to sell as provided above, such Holder failing to request inclusion in the Special Demand Registration shall not have a right to request inclusion of such Holder's Registrable Securities in a future demand registration or Company purchase of shares with respect to the Registrable Securities. Any Holder, a representative of whom is on the Company's Board of Directors and which representative voted not to register the shares upon such a request, shall not be entitled to cause the inclusion of such Holder's shares in any such Special Demand Registration or Company purchase of shares. (iii) Any purchase of shares by the Company pursuant to Section 2.2(a)(ii) above shall be consummated (a "Closing") within 10 Business Days after the expiration of the 10 Business Day period stated above that begins with the receipt by the applicable Holder of the Special Demand Notice. Any Closing shall take place at the offices of the Company at 1100 Poydras Street, Suite 2000, New Orleans, Louisiana, at 9:00 a.m. At the Closing, the Company will deliver to each Holder selling shares a certified or bank cashier's check or evidence of a wire transfer to the Holder's designated account, in the amount of the purchase price for the Shares sold by such Holder, against delivery of the certificate evidencing such shares duly endorsed or accompanied by a stock power duly endorsed in blank. (iv) For purposes of this Section 2.2(a), the term "Fair Market Value" shall mean, with respect to shares of Common Stock, as of any date, (A) if the Common Stock is listed or admitted to trade on a national securities exchange, the closing price of the Common Stock on the composite tape, as published in The Wall Street Journal, of the principal national securities exchange on which the Common Stock is so listed or admitted to trade, on such date or, if there is no trading in shares of the Common Stock on such date, then the closing price of the Common Stock as quoted on such composite tape on the next preceding date on which there was trading in such shares of Common Stock; (B) if the Common Stock is not listed or admitted to trade on a national securities exchange, then the closing price of the Common Stock as quoted on the National Market System of the National Association of Securities Dealers, Inc. ("NASD"); (C) if the Common Stock is not listed or admitted to trade on a national securities exchange or the National Market System of the the National Association of Securities Dealers, Inc. ("NASD"), the mean between the bid and asked price for the Common Stock on such date, as furnished by NASD through NASDAQ or a similar organization if NASDAQ is no longer reporting such information; or (D) if the Common Stock is not listed or admitted to trade on a national securities exchange or the National Market System of the NASD and if bid and asked prices for the Common Stock are not so furnished by the NASD or a similar organization, the value established by the Board of Directors of the Company in good faith but in any event not less than 90% of the price at which the common stock issued by the Company was last sold (other than pursuant to options or warrants). Fair Market Value shall be determined without regard to any restriction other than a restriction which, by its terms, will never lapse. (v) All requests made pursuant to this Section 2.2(a) will specify the amount of Registrable Securities to be registered and will also specify the intended methods of disposition thereof. 5

(vi) Each of the terms "Hornbecks" and "Cari," as used in this Section 2.2, shall also refer collectively to any Holders that are transferees of such entity. (b) Number of Demand Registrations; Payment of Expenses. Notwithstanding the percentage limitation in Section 2.2(a)(i), after June 5, 2000, each of the Hornbecks and Cari shall, subject to the provisions of paragraph (c) below, be entitled to one Demand Registration, which in each case must become effective to count as having occurred. The Company shall pay all Registration Expenses (as hereinafter defined) of each Demand Registration, whether or not it becomes effective. The Company's obligation to make Demand Registrations shall, subject to the provisions of paragraph (c) below, cease on the date seven years after the date hereof. (c) Supplemental Demand Registrations. If the managing underwriter or underwriters of a Demand Registration (or in the case of a Demand Registration not being underwritten, the holders of a majority of the Registrable Securities being registered therein), advise the Company in writing that in its or their opinion the number of securities proposed to be sold in such Demand Registration exceeds the number which can be sold in such offering at the desired price, the Company will include in such registration only the number of securities which, in the opinion of such underwriter or underwriters (or Holders, as the case may be) can be sold, selected pro rata among the Holders which have requested to be included in such Demand Registration. In such event, the Holders of the shares requested to be included but not so included (the "Excess Requested Shares") shall be treated as if there had been no Demand Registration, and shall be entitled to the benefit of this Section 2.2 with respect to the Excess Requested Shares, provided that any subsequent Demand Registration shall not be required to become effective within twelve months of the effective date of any prior Demand or Piggy-back Registration hereunder. With respect to such a Demand Registration subsequently initiated, only Excess Requested Shares shall be deemed Registrable Shares, and no Holder shall have any further Demand Registration rights with respect to shares for which he failed to request inclusion pursuant to Section 2.2(a) in a prior Demand Registration that became effective. (d) Selection of Underwriters. If any Demand Registration is an underwritten offering, the holders of a majority of the Registrable Securities to be included in such Demand Registration will select a managing underwriter or underwriters acceptable to the Company to administer the offering, which acceptance will not be unreasonably withheld. (e) Company Registration. Notwithstanding the provisions of paragraphs 2.2(a)-(d), the Company shall not be obligated to effect a registration requested pursuant to paragraphs 2.2(a)-(d) if (i) within 30 days after receiving the notice provided by a Holder under paragraphs 2.2(a)-(d), the Company notifies all Holders of Registrable Securities of its intention to file a registration statement for a firm commitment underwritten public offering of Common Stock and within ninety days after providing such notice, files a registration statement for such offering and (ii) the Company has never before exercised its rights under this paragraph 2.2(e). In such case, the Holders shall have all the rights provided herein as if no such demand for registration had been requested. If at any time the Company fails diligently to pursue its registration statement or the offering, the provisions of the preceding sentence shall not apply, and the Company shall be obligated to satisfy its obligations under paragraphs 2.2(a)-(d). With 6

respect to such registration, the Company shall have sole authority to select or terminate the employment of underwriters, and to make all decisions in connection with the filing, effectiveness and consummation of the proposed offering, subject to the express provisions hereof. (f) The obligations of the Company under Sections 2.2(a)-(d) are subject to each of the following limitations, conditions and qualifications: (i) The Company shall be entitled to postpone for a reasonable period of time (not exceeding 60 days) the filing (but not the preparation) of any registration statement otherwise required to be prepared and filed by it pursuant hereto if, at the time the Company receives a request for such registration, the Company is in possession of material non-public information that would be required to be disclosed in a registration statement but that has not been and will otherwise not be disclosed to the public and the Company deems disclosure not to be in the best interests of the Company and its stockholders (for this purpose, the interest of the Holders in effecting the registration shall not be considered). The Company shall be entitled to postpone the filing of such a registration statement for additional 60-day periods (not to exceed in any event an aggregate of 120 days) if it delivers to the Holders of Registrable Securities an opinion of counsel to the effect that there is a reasonable likelihood that the filing of a registration statement would result in the disclosure of material non-public information that would be required to be disclosed in a registration statement, the disclosure of which at such time appears not to be in the best interests of the Company and its stockholders (for this purpose, the interest of the Holders in effecting the registration shall not be considered). (ii) The Company shall be entitled to postpone for a reasonable period of time (not exceeding 90 days) the distribution of preliminary or final prospectuses under any registration statement required to be prepared and filed by it pursuant hereto, if at the time such distribution would otherwise be made the Company is engaged in an issuer tender offer within the meaning of Section 13(e) of the Securities Exchange Act of 1934, as amended, for securities of the same class as the Registrable Securities, unless the Holders of the Registrable Securities proposed to be registered can obtain a no-action letter from the staff of the Securities and Exchange Commission (the "Commission") to the effect that the staff would not recommend enforcement action to the Commission if offers or sales were made pursuant to a prospectus under such circumstances. (iii) The Company shall be entitled to postpone for a reasonable period of time (not exceeding 90 days) the effectiveness (but not the filing or preparation) of any registration statement otherwise required to be prepared and filed by it pursuant hereto if, within 10 Business Days after it receives a request for a registration pursuant hereto, the Company's investment banking firm determines (and the Company so notifies the Holders of Registrable Securities) that in its judgment, such registration and offering would materially interfere with any financing, acquisition, corporate reorganization or other material transaction involving the Company that prior to such request the Board of Directors of the Company had agreed by resolution to pursue. (iv) If pursuant to a request for Demand Registration the Company delivers to the Holders of Registrable Securities proposed to be registered an opinion 7

of counsel to the effect that sales of such Registrable Securities thereunder might cause the Company to lose a material amount of net operating losses or other tax carryforwards, the Company may postpone the filing of the registration statement otherwise required to be filed by it pursuant hereto, but only to the extent required to protect such carryforwards, and only if it is first determined that such protection cannot be effected by reducing the number of shares being registered. 2.3 Holdback Agreements; Requirements of Holders. (a) Restrictions on Public Sale by Holders of Registrable Securities. To the extent not inconsistent with applicable law, including insurance codes, each Holder of Registrable Securities that are included in a registration statement which registers Registrable Securities pursuant to this Agreement agrees not to effect any public sale or distribution of the issue being registered or a similar security of the Company or any securities convertible into or exchangeable or exercisable for such securities, during the 14 days prior to, and during the 90-day period beginning on, the effective date of a registration statement filed by the Company (except as part of such registration), but only if and to the extent requested in writing (with reasonable prior notice) by the managing underwriter or underwriters in the case of an underwritten public offering by the Company of securities similar to the Registrable Securities; provided, however, that the period of time for which the Company is required to keep such registration statement which includes Registrable Securities continuously effective shall be increased by a period equal to such requested holdback period. (b) Restrictions on Public Sale by the Company. The Company agrees not to effect any public sale or distribution of any securities similar to those being registered, or any securities convertible into or exchangeable or exercisable for such securities, during the 14 days prior to, and during the 90-day period beginning on, the effective date of any registration statement in which the Holders of Registrable Securities are participating (except pursuant to such registration statement). (c) Cooperation by Holders. The offering of Registrable Securities by any Holder shall comply in all respects with the applicable terms, provisions and requirements set forth in this Agreement, and such Holder shall timely provide the Company with all information and materials required to be included in a registration statement that (a) relate to the offering, (b) are in possession of such Holder, and (c) relate to such Holder, and to take all such action as may be reasonably required in order not to delay the registration and offering of the securities by the Company. The Company shall have no obligation to include in such registration statement shares of a Holder who has failed to furnish such information which, in the written opinion of counsel to the Company, is required in order for the registration statement to be in compliance with the 1933 Act. 2.4 Registration Procedures. Whenever any Registrable Securities are to be registered pursuant to Sections 2.1 or 2.2 of this Agreement, the Company will use reasonable diligence to effect the registration of such Registrable Securities in accordance with the intended method of disposition thereof as quickly as practicable. In connection with any Piggy-back Registration or Demand Registration, the Company will as expeditiously as possible: 8

(a) prepare and file with the Commission a registration statement which includes the Registrable Securities and use reasonable diligence to cause such registration statement to become effective; provided, however, that before filing a registration statement or prospectus or any amendments or supplements thereto, including documents incorporated by reference after the initial filing of the registration statement, the Company will furnish to the Holders of the Registrable Securities covered by such registration statement and the underwriters, if any, draft copies of all such documents proposed to be filed at least 5 Business Days prior thereto, which documents will be subject to the reasonable review of such Holders and underwriters, and the Company will not file any registration statement or amendment thereto or any prospectus or any supplement thereto (including such documents incorporated by reference) to which holders of a majority of the Registrable Securities covered by such registration statement or the underwriters with respect to such Registrable Securities, if any, shall reasonably object, and will notify each Holder of the Registrable Securities of any stop order issued or threatened by the Commission in connection therewith and take all reasonable actions required to prevent the entry of such stop order or to remove it if entered; (b) prepare and file with the Commission such amendments and post-effective amendments to the registration statement as may be necessary to keep the registration statement effective for a period of not less than six months (or such shorter period which will terminate when all Registrable Securities covered by such registration statement have been sold or withdrawn, but not prior to the expiration of the 90-day period referred to in Section 4(3) of the 1933 Act and Rule 174 thereunder, if applicable); cause the prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the 1933 Act; and comply with the provisions of the 1933 Act applicable to it with respect to the disposition of all securities covered by such registration statement during the applicable period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement or supplement to the prospectus; (c) furnish to any Holder of Registrable Securities included in such registration statement and the underwriter or underwriters, if any, without charge, such number of conformed copies of the registration statement and any post-effective amendment thereto and such number of copies of the prospectus (including each preliminary prospectus) and any amendments or supplements thereto, and any documents incorporated by reference therein, as such Holder or underwriter may request in order to facilitate the disposition of the Registrable Securities being sold by such Holder (it being understood that the Company consents to the use of the prospectus and any amendment or supplement thereto by each Holder of Registrable Securities covered by the registration statement and the underwriter or underwriters, if any, in connection with the offering and sale of the Registrable Securities covered by the prospectus or any amendment or supplement thereto); provided, however, that before filing a registration statement or prospectus or any amendments or supplements thereto, the Company will furnish to one counsel selected by the Holders of a majority of the Registrable Securities covered by such registration statement, copies of all documents proposed to be filed which documents will be subject to the review of such counsel; (d) notify each Holder of Registrable Securities included in such registration statement, at any time when a prospectus relating thereto is required to be delivered 9

under the Securities Act, when the Company becomes aware of the happening of any event as a result of which the prospectus included in such registration statement (as then in effect) contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements therein (in the case of the prospectus or any preliminary prospectus, in light of the circumstances under which they were made) not misleading and, as promptly as practicable thereafter, prepare and file with the Commission and furnish a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; (e) use reasonable diligence to cause all Registrable Securities included in such registration statement to be listed, by the date of the first sale of Registrable Securities pursuant to such registration statement, on each securities exchange (including, for this purpose, NASDAQ) on which the Common Stock of the Company is then listed or proposed to be listed, if any; (f) make generally available to its security holders an earnings statement satisfying the provisions of Section 11(a) of the 1933 Act no later than 45 days after the end of the 12-month period beginning with the first day of the Company's first fiscal quarter commencing after the effective date of the registration statement, which earnings statement shall cover said 12-month period, which requirement will be deemed to be satisfied if the Company timely files complete and accurate information on Forms 10-Q, 10-K and 8-K under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and otherwise complies with Rule 158 under the 1933 Act as soon as feasible; (g) make every reasonable effort to obtain the withdrawal of any order suspending the effectiveness of the registration statement at the earliest possible moment; (h) if requested by the managing underwriter or underwriters or any Holder of Registrable Securities covered by the registration statement, promptly incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or underwriters or such Holder requests to be included therein, including, without limitation, with respect to the number of Registrable Securities being sold by such Holder to such underwriter or underwriters, the purchase price being paid therefor by such underwriter or underwriters and any other terms of the underwritten offering of such Registrable Securities, and promptly make all required filings of such prospectus supplement or post-effective amendment; (i) as promptly as practicable after filing with the Commission of any document which is incorporated by reference into a registration statement, deliver a copy of such document to each Holder of Registrable Securities covered by such registration statement; (j) on or prior to the date on which the registration statement is declared effective, use reasonable diligence to register or qualify, and cooperate with the Holders of Registrable Securities included in such registration statement, the underwriter or underwriters, if any, and their counsel, in connection with the registration or qualification of the Registrable 10

Securities covered by the registration statement for offer and sale under the securities or blue sky laws of each state and other jurisdiction of the United States as any such Holder or underwriter reasonably requests in writing, to use reasonable diligence to keep each such registration or qualification effective, including through new filings, or amendments or renewals, during the period such registration statement is required to be kept effective and to do any and all other acts or things necessary or advisable to enable the disposition in all such jurisdictions of the Registrable Securities covered by the applicable registration statement; provided that the Company will not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject; (k) cooperate with the Holders of Registrable Securities covered by the registration statement and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing securities to be sold under the registration statement, and enable such securities to be in such denominations and registered in such names as the managing underwriter or underwriters, if any, or such Holders may request, subject to the underwriters' obligation to return any certificates representing securities not sold; (l) use reasonable diligence to cause the Registrable Securities covered by the registration statement to be registered with or approved by such other governmental agencies or authorities within the United States as may be necessary to enable the seller or sellers thereof or the underwriter or underwriters, if any, to consummate the disposition of such securities; (m) enter into such customary agreements (including an underwriting agreement in customary form) and take all such other reasonable actions as the Holders of a majority of the Registrable Securities being sold or the underwriters retained by Holders participating in an underwritten public offering, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities; (n) make available for inspection by any holder of Registrable Securities included in such registration statement, any underwriter participating in any disposition pursuant to such registration statement, and any attorney, accountant or other agent retained by any such seller or underwriter (collectively, the "Inspectors"), all nonconfidential financial and other records, pertinent corporate documents and properties of the Company (collectively, the "Records"), as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company's officers, directors and employees to supply all Records reasonably requested by any such Inspector in connection with such registration statement; and (o) use reasonable diligence in connection with any underwritten offering to obtain a "cold comfort" letter from the Company's independent public accountants in customary form and covering such matters of the type customarily covered by cold comfort letters as the managing underwriter or underwriters may reasonably request. 11

Each Holder, upon receipt of any notice from the Company of the happening of any event of the kind described in subsection (d) of this Section 2.4, will forthwith discontinue disposition of the Registrable Securities until such Holder's receipt of the copies of the supplemented or amended prospectus contemplated by subsection (d) of this Section 2.4 or until it is advised in writing (the "Advice") by the Company that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings which are incorporated by reference in the prospectus, and, if so directed by the Company, such Holder will, or will request the managing underwriter or underwriters, if any, to, deliver to the Company (at the Company's expense) all copies, other than permanent file copies then in such Holder's possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. In the event the Company shall give any such notice, the time periods mentioned in subsection (b) of this Section 2.4 shall be extended by the number of days during the period from and including the date of the giving of such notice to and including the date when each seller of Registrable Securities covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by subsection (d) of this Section 2.4 hereof or the Advice. If such registration statement refers to any Holder by name or otherwise as the Holder of any securities of the Company then such Holder shall have the right to require (i) the insertion therein of language, in form and substance satisfactory to such holder, to the effect that the holding by such Holder of such securities is not to be construed as a recommendation of such Holder of the investment quality of the Company's securities covered thereby and that such holding does not imply that such Holder will assist in meeting any future financial requirements of the Company, or (ii) in the event that such reference to such Holder by name or otherwise is not required by the 1933 Act or any similar federal statute then in force, the deletion of the reference to such Holder. 2.5 Registration Expenses. All expenses incident to the Company's performance of or compliance with this Agreement, including without limitation, all SEC and securities exchange or National Association of Securities Dealers, Inc. registration and filing fees, fees and expenses (other than the pro rata portion of filing fees required by state law attributable to the securities to be sold) of compliance with securities or blue sky laws (including fees and disbursements of counsel in connection with blue sky qualifications of the Registrable Securities), rating agency fees, printing expenses, messenger and delivery expenses, internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the fees and expenses incurred in connection with the listing of the securities to be registered on each securities exchange on which similar securities issued by the Company are then listed and fees and disbursements of counsel for the Company and its independent certified public accountants (including the expenses of any special audit or "cold comfort" letters required by or incident to such performance), securities act liability insurance (if the Company elects to obtain such insurance), the fees and expenses of any special experts retained by the Company in connection with such registration (but not including any underwriting fees, discounts or commissions attributable to the sale of Registrable Securities), and any out-of-pocket expenses of the Holders of Registrable Securities excluding any travel costs and counsel fees except as set forth above (all such expenses being herein called "Registration Expenses"), will be borne by the Company. 12

2.6 Indemnification; Contribution. (a) Indemnification by the Company. The Company agrees to indemnify and hold harmless each Holder of Registrable Securities, its officers, directors and each Person who controls such Holder (within the meaning of the 1933 Act), and any Agent (as hereinafter defined) or investment advisor thereof against all losses, claims, damages, liabilities and expenses (including reasonable costs of investigation) (collectively, "Liabilities") arising out of or based upon any untrue or alleged untrue statement of material fact contained in any registration statement, any amendment or supplement thereto, any prospectus or preliminary prospectus or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as any such Liabilities arise out of or are based upon any untrue statement or omission based upon information with respect to such indemnified Person furnished in writing to the Company by such indemnified Person expressly for use therein. In connection with an underwritten offering, the Company will indemnify the underwriters thereof, their officers and directors and each Person who controls such underwriters (within the meaning of the 1933 Act) to the same extent as provided above with respect to the indemnification of the Holders of Registrable Securities or to such other extent as the Company and such underwriters may agree. For purposes of this Section 2.6(a), an "Agent" of a Holder of Registrable Securities is any person acting for or on behalf of such Holder with respect to the holding or sale of such Registrable Securities. (b) Indemnification by Holders of Registrable Securities. In connection with any registration statement in which a Holder of Registrable Securities is participating, each such Holder will furnish to the Company in writing such information with respect to the name and address of such Holder and the amount of Registrable Securities held by such Holder and such other information as the Company shall reasonably request for use in connection with any such registration statement or prospectus, and agrees to indemnify, to the extent permitted by law, the Company, its directors and officers and each Person who controls the Company (within the meaning of the 1933 Act) against any losses, claims, damages, liabilities and expenses resulting from any untrue statement of a material fact or any omission of a material fact required to be stated in the registration statement or prospectus or any amendment thereof or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the extent, that such untrue statement or omission is based upon any information with respect to such Holder so furnished in writing by such Holder specifically for inclusion in any prospectus or registration statement. In no event shall the liability of any selling Holder of Registrable Securities hereunder be greater in amount than the dollar amount of the proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation. (c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder agrees to give prompt written notice to the indemnifying party after the receipt by such Person of any written notice of the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which such Person may claim indemnification or contribution pursuant to this Agreement and, unless in the written opinion of counsel for such indemnified party a conflict of interest may exist between such indemnified party and the indemnifying party with respect to such claim, permit the indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to such indemnified party. 13

Whether or not such defense is assumed by the indemnifying party, the indemnifying party will not be subject to any liability for any settlement made without its consent. No indemnifying party will consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. If the indemnifying party is not entitled to, or elects not to, assume the defense of a claim, it will not be obligated to pay the fees and expenses of more than one counsel with respect to such claim, unless in the opinion of counsel for any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of such additional counsel or counsels. (d) Contribution. If the indemnification provided for in this Section 2.6 from the indemnifying party is unavailable to an indemnified party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified parties in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified parties shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact, has been made by, or relates to information supplied by, such indemnifying party or indemnified parties, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 2.6(c), any legal or other fees or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 2.6(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 2.6(d), no selling Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities of such selling Holder were offered to the public exceeds the amount of any damages which such selling Holder has otherwise been required to pay by reason of such untrue statement or omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The obligations of the Company pursuant to this Section 2.6 shall be further subject to such additional express agreements of the Company as may be required to facilitate an underwritten offering, provided that no such agreement shall in any way limit the rights of the Holders of Registrable Securities under this Agreement, or create additional obligations of such Holders not set forth herein, except as otherwise expressly agreed in writing by any such Holders. 14

2.7 Participation in Underwritten Registrations. No Holder of Registrable Securities may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder's securities on the terms of and on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements (which shall be the Company in the case of an offering of securities by the Company) and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 2.8 Rule 144. The Company covenants that, upon any registration statement covering Company securities becoming effective, it will file the reports required to be filed by it under the 1933 Act and the Exchange Act and the rules and regulations adopted by the Commission thereunder (or, if the Company is not required to file such reports, it will, upon the request of any Holder of Registrable Securities, make publicly available other nonconfidential information so long as necessary to permit sales under Rule 144 under the 1933 Act) , and it will take such other action as any Holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the 1933 Act within the limitation of the exemptions provided by (a) Rule 144 under the 1933 Act, as such Rule may be amended from time to time, or (b) any similar rule or regulation hereafter adopted by the Commission. Upon the request of any Holder of Registrable Securities, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements. Section 3. Other Registration Rights. The Company may only grant registration rights to any person (including the Holders of Registrable Securities) with respect to any securities of the Company that are granted in accordance with the terms of this Section 3. Such new rights must either (i) if identical to those granted herein (through being designated as "Purchaser Shares" hereunder),be approved in writing by Holders of a majority of the then Registrable Securities, or (ii) if not identical to those granted herein, nevertheless not be inconsistent with the terms of this Agreement while providing that (a) with respect to demand registration rights granted to other persons, the Holders of Registrable Securities have a piggy-back right upon the exercise of such new rights and shall be included in such registration statement on the same terms and conditions as the holders of the new rights, subject to possible reduction at the initiative of the managing underwriter or underwriters on terms substantially equivalent to those set forth in Section 2.1 and with respect to piggy-back rights granted to other persons, such other persons' rights to be included in a registration statement shall not be superior to the rights of the Holder. The Company may grant registration rights that would permit any person the right to piggy-back or may itself exercise the right to piggy-back on any Demand Registration, provided that if the managing underwriter or underwriters of such offering delivers an opinion to the Holders of Registrable Securities that the total amount of securities which they and the holders of such new piggy-back rights intend to include in any Demand is so large as to materially and adversely affect the success of such offering (including the price at which such securities can be sold), then only the amount or kind of securities to be offered for the account of holders of such new piggy-back rights, or the Company if it is exercising piggy-back rights, will be reduced to the extent necessary to reduce the total amount of securities to be included in such offering to the amount recommended by the managing underwriter prior to any reduction in the amount of 15

Registrable Securities to be included; and further provided that if such offering is not underwritten, then such piggy-back shall only be exercised with the consent of the Holders of a majority of the Registrable Securities being offered.

(a) Subsequent to the Company becoming a reporting company under the Exchange Act, TMH, TAH and Cari each agrees to give the Company ten (10) days' written notice of the occurrence of an "Event" as that term is hereinafter defined.

Any holder electing to participate in such registration agrees to be bound by the terms and conditions of this Agreement. The Company shall use reasonable diligence to cause the managing underwriter or underwriters of a proposed underwritten offering to permit the Holders of Registrable Securities requested to be included in the registration for such offering to include such securities in such offering on the same terms and conditions as any similar securities of the Company included therein. Notwithstanding the foregoing, if the managing underwriter or underwriters of such offering delivers a written opinion to the holders of Registrable Securities that the total amount of securities which they or the Company and any other Persons intend to include in such offering is sufficiently large to materially and adversely affect the success of such offering, then the amount or kind of Registrable Securities to be offered for the accounts of Holders of Registrable Securities shall be reduced pro rata (based on the number of shares of Common Stock requested to be included in such offering by each such Holder) with respect to each Holder requesting inclusion therein to the extent necessary, in the opinion of such managing underwriter, to reduce the total amount of securities to be included in such offering to the amount recommended by such managing underwriter; provided, that the reduction imposed upon Holders of Registrable 3

Securities shall not be greater, on a fractional basis, than the reduction imposed upon other Persons whose piggy-back registration rights are pari passu with those granted hereby with respect to the amount of securities requested for inclusion in such registration. (b) Notwithstanding anything to the contrary contained in this Agreement, the Company shall not be required to include Registrable Securities in any registration statement if the proposed registration is (i) a registration of a stock option or other employee incentive compensation plan or of securities issued or issuable pursuant to any such plan, (ii) a registration of securities issued or issuable pursuant to a stockholder reinvestment plan, or other similar plan, (iii) a registration of securities issued in exchange for any securities or any assets of, or in connection with a merger or consolidation with, an unaffiliated company, or (iv) a registration of securities pursuant to a "rights" or other similar plan designed to protect the Company's stockholders from a coercive or other attempt to take control of the Company. (c) The Company may withdraw any registration statement and abandon any proposed offering initiated by the Company without the consent of any Holder of Registrable Securities, notwithstanding the request of any such Holder to participate therein in accordance with this provision, if the Company determines in its sole discretion that such action is in the best interests of the Company and its stockholders (for this purpose, the interest of the Holders in effecting the registration and offering shall not be considered).

(i) Subject to the conditions stated in this Section 2.2 herein and provided the Common Stock is registered under Section 12 of the Exchange Act, at any time after the date hereof, the Holders of at least 50.1% of the shares of Registrable Securities may make a written request to the Company for registration with the Commission by such Holders, under and in accordance with the provisions of the 1933 Act, of the resale of all or part of their Registrable Securities (a "Demand Registration"); provided that the Company may if necessary 4

delay the filing of such Demand Registration for such reasonable period of time, not to exceed 90 days, as is necessary to prepare the financial statements of the Company for the fiscal period most recently ended prior to such written request. Within 10 Business Days after receipt of such request, the Company will serve written notice (the "Notice") of such registration request to all Holders of the Registrable Securities and holders of Company securities possessing equivalent registration rights and the Company will include in such registration all Registrable Securities and securities eligible for registration of such holders with respect to which the Company has received written requests for inclusion therein within 10 Business Days after the receipt by the applicable holder of the Notice. Any Holder by electing to participate in such registration agrees to be bound by the terms and conditions of this Agreement. (ii) Subject to the conditions stated hereinafter in this Section 2.2(a), at any time after the earlier of (x) the fourth anniversary of the date hereof or (y) the Repurchase Event Date (as defined in Section 2.2(a)(vi), if the Company is not Publicly Traded and SCF continues to own at least 80% of the shares of Common Stock acquired by SCF in the Private Placement, SCF may make a written request (a "Special Demand") to the Company for registration with the Commission of the offer and sale of SCF's shares of the Registrable Securities under and in accordance with the provisions of the 1933 Act (the "Special Demand Registration"); provided, however, that if the Repurchase Event Date is based on an election or elections to cause the repurchase of less than all of the Warrants or a Board Determination to redeem less than all of the Warrants or to enter into a transaction with the holders of Warrants to substantially the same effect as a redemption or repurchase of less than all of the Warrants, then the shares which SCF shall be entitled to include in a Special Demand shall be limited to that number determined by multiplying 8,150,944 (or such lesser number of shares of Common Stock as is then owned by SCF) by a fraction the numerator of which is the number of shares of Common Stock otherwise issuable pursuant to the Warrants to be so redeemed, repurchased or subjected to a transaction to substantially the same effect and the denominator of which shall be 11,904,761 or such lesser number of Warrants as are then exercisable. If SCF is not permitted to include all of its shares of Registrable Securities in a Special Demand, SCF shall continue to have the right to make Special Demands pursuant to the terms of this Section. Following receipt of such request, the Company shall, no later than 40 Business Days after receipt of such request, notify SCF of its election to either (1) file the registration statement covering such shares for sale by SCF, provided that the Company may, if necessary, delay the filing of any registration statement relating to any such Special Demand Registration for such reasonable period of time, not to exceed 90 days, as is necessary to prepare the financial statements of the Company for the fiscal period most recently ended prior to such written request, or (2) if the Company is not at such time registered under the Exchange Act, purchase the number of shares requested to be registered from SCF at a price per share equal to the Fair Market Value for shares of Common Stock. In the event the Company elects to exercise its rights under (2) above, SCF shall not be required to sell such Registrable Securities to the Company, but because the Company offers to purchase such Registrable Securities, its obligation to register such Registrable Securities on demand under this Section 2.2(a)(ii) shall have been satisfied. Within 10 Business Days after the Company provides its notice of election to SCF of its intention to file a registration statement at SCF's request, the Company will serve written notice (the "Special Demand Notice") of such registration request to all Holders of Registrable Securities and the Company will include in such registration together with the shares of SCF, all such Registrable Securities with respect to which 5

the Company has received written requests for inclusion therein within 10 Business Days after the receipt by the applicable Holder of the Special Demand Notice. Any Holder by electing to participate in such registration agrees to be bound by the terms and conditions of this Agreement. If a Holder of Registrable Securities shall fail to request inclusion in such Special Demand Registration and such Special Demand Registration shall not become effective under the 1933 Act, such Holder failing to request inclusion in the Special Demand Registration shall not have a right to request inclusion of such Holder's Registrable Securities in a future demand registration with respect to the Registrable Securities. Any Holder, a representative of whom is on the Company's Board of Directors and which representative voted not to register the shares upon such a request, shall not be entitled to cause the inclusion of such Holder's shares in any such Special Demand Registration. If the Company elects to effect a registration pursuant to a Special Demand, then after taking into account the shares to be sold by SCF and any other selling stockholders in such registration, the Company will include in the registration statement such additional shares to be sold by the Company so that the aggregate offering price of all shares to be sold under such registration statement will equal at least $25 million. (iii) Any purchase of shares by the Company pursuant to Section 2.2(a)(ii) above shall be consummated (a "Closing") within 150 Days after the expiration of the 40-Business Day period stated above that begins with the receipt by the Company of SCF's request for registration under Section 2.2(a)(ii). Any Closing shall take place at the offices of the Company at 414 N. Causeway Boulevard, Mandeville, Louisiana 70448, at 9:00 a.m. At the Closing, the Company will deliver a certified or bank cashier's check or evidence of a wire transfer to SCF's designated account, in the amount of the purchase price for the shares of Common Stock sold by such Holder, against delivery of the certificate evidencing such shares duly endorsed or accompanied by a stock power duly endorsed in blank. (iv) Whenever as a result of a Special Demand the Company determines to consider its election under Section 2.2(a)(ii)(2) and, accordingly, a determination of the Fair Market Value of the Common Stock must be made and such determination shall be made in good faith by the Board of Directors of the Company within 15 Business Days following the Special Demand. The Company shall notify SCF of such determination no later than two Business Days following the date of such determination. If SCF disagrees with the Fair Market Value as so determined by the Board of Directors, SCF shall so notify the Company within three Business Days after receipt of notice from the Board of Directors of its determination and SCF shall include in such notice (a "Dissenting Notice"), SCF's estimate of the Fair Market Value. In the event SCF and the Company are unable to reach an agreement regarding the Fair Market Value within two Business Days after receipt by the Company of the Dissenting Notice, then the Fair Market Value shall be determined by an independent third party, knowledgeable and experienced in the valuation of private businesses, and who is mutually acceptable to the Company and SCF (the "Appraiser"). In the event the Company and SCF are unable to agree upon an Appraiser within two Business Days after receipt by the Company of the Dissenting Notice, each party shall select an investment banking firm and the two investment banking firms so selected shall, within three Business Days, select a third investment banking firm to be the Appraiser. The Appraiser shall make a determination of Fair Market Value within 15 Business Days of his appointment and shall notify the Company and SCF of such determination, which shall be binding on all parties if the Company elects to proceed under Section 2.2(a)(ii)(2). 6

Costs associated with the determination of Fair Market Value shall be borne by the Company unless the Fair Market Value as determined by the Appraiser is closer to the value determined by the Board of Directors than the value estimated by SCF, in which event SCF shall pay such costs; provided, that if, following the appraisal the Company elects under Section 2(a)(ii) to register the shares pursuant to the Special Demand, the Company shall pay the costs of the Appraiser. (v) All requests made pursuant to this Section 2.2(a) will specify the amount of Registrable Securities to be registered and will also specify the intended methods of disposition thereof. (vi) For purposes of Section 2.2(a)(ii), a Repurchase Event Date shall occur if (i) the holders of warrants (the "Warrants") that were originally issued to Joint Energy Development Investment II Limited Partnership and Enron Capital & Trade Resources Corp. on June 5, 1998 give the Company notice that such holders are exercising any of their rights under Section 3 of Warrants to require the Company to repurchase Warrants or (ii) the Board of Directors of the Company determines ("Board Determination") to redeem Warrants or to enter into a transaction with the holders of Warrants to substantially the same effect as a redemption or repurchase of Warrants; provided, however, that, if the holders of Warrants elect to withdraw their notice of election to require repurchase of Warrants or the Board of Directors elects to rescind the Board Determination, SCF's right to a Special Demand prior to the fourth anniversary of the date hereof shall simultaneously terminate. The Company shall promptly give SCF notice of any Repurchase Event Date. (b) Supplemental Demand Registrations. If the managing underwriter or underwriters of a Demand Registration (or in the case of a Demand Registration not being underwritten, the holders of a majority of the Registrable Securities being registered therein), advise the Company in writing that in its or their opinion the number of securities proposed to be sold in such Demand Registration exceeds the number which can be sold in such offering at the desired price, the Company will include in such registration only the number of securities which, in the opinion of such underwriter or underwriters (or Holders, as the case may be) can be sold, selected pro rata among the Holders which have requested to be included in such Demand Registration. In such event, the Holders of the shares requested to be included but not so included (the "Excess Requested Shares") shall be treated as if there had been no Demand Registration, and shall be entitled to the benefit of this Section 2.2 with respect to the Excess Requested Shares, provided that any subsequent Demand Registration shall not be required to become effective within twelve months of the effective date of any prior Demand or Piggy-back Registration hereunder. With respect to such a Demand Registration subsequently initiated, only Excess Requested Shares shall be deemed Registrable Shares, and no Holder shall have any further Demand Registration rights with respect to shares for which he failed to request inclusion pursuant to Section 2.2(a) in a prior Demand Registration that became effective. (c) Selection of Underwriters. If any Demand Registration is an underwritten offering, the holders of a majority of the Registrable Securities to be included in such Demand Registration will select a managing underwriter or underwriters acceptable to the Company to administer the offering, which acceptance will not be unreasonably withheld. 7

(d) Company Registration. Notwithstanding the provisions of paragraphs 2.2(a)-(c), the Company shall not be obligated to effect a registration requested pursuant to paragraphs 2.2(a)-(c) (other than pursuant to a Special Demand) if within 10 Business Days after receiving the notice provided by a Holder under paragraphs 2.2(a)-(c) (other than a Special Demand), the Company notifies all Holders of Registrable Securities of its intention to file a registration statement for a firm commitment underwritten public offering of Common Stock and within ninety days after providing such notice, files a registration statement for such offering. In such case, the Holders shall have all the rights provided herein as if no such demand for registration had been requested. If at any time the Company fails diligently to pursue its registration statement or the offering, the provisions of the preceding sentence shall not apply, and the Company shall be obligated to satisfy its obligations under paragraphs 2.2(a)-(c). With respect to such registration, the Company shall have sole authority to select or terminate the employment of underwriters, and to make all decisions in connection with the filing, effectiveness and consummation of the proposed offering, subject to the express provisions hereof. (e) The obligations of the Company under Sections 2.2(a)-(c) are subject to each of the following limitations, conditions and qualifications: (i) The Company shall be entitled to postpone for a reasonable period of time (not exceeding 60 days) the filing (but not the preparation) of any registration statement otherwise required to be prepared and filed by it pursuant hereto if, at the time the Company receives a request for such registration, the Company is in possession of material non-public information that would be required to be disclosed in a registration statement but that has not been and will otherwise not be disclosed to the public and the Company deems disclosure not to be in the best interests of the Company and its stockholders (for this purpose, the interest of the Holders in effecting the registration shall not be considered). The Company shall be entitled to postpone the filing of such a registration statement for additional 30-day periods (not to exceed in any event an aggregate of 90 days) if it delivers to the Holders of Registrable Securities an opinion of counsel to the effect that there is a reasonable likelihood that the filing of a registration statement would result in the disclosure of material non-public information that would be required to be disclosed in a registration statement, the disclosure of which at such time appears not to be in the best interests of the Company and its stockholders (for this purpose, the interest of the Holders in effecting the registration shall not be considered). (ii) The Company shall be entitled to postpone for a reasonable period of time (not exceeding 90 days) the distribution of preliminary or final prospectuses under any registration statement required to be prepared and filed by it pursuant hereto, if at the time such distribution would otherwise be made the Company is engaged in an issuer tender offer within the meaning of Section 13(e) of the Exchange Act, as amended, for securities of the same class as the Registrable Securities, unless the Holders of the Registrable Securities proposed to be registered can obtain a no-action letter from the staff of the Commission to the effect that the staff would not recommend enforcement action to the Commission if offers or sales were made pursuant to a prospectus under such circumstances. 8

(iii) The Company shall be entitled to postpone for a reasonable period of time (not exceeding 90 days) the effectiveness (but not the filing or preparation) of any registration statement otherwise required to be prepared and filed by it pursuant hereto if, within 10 Business Days after it receives a request for a registration pursuant hereto, the Company's investment banking firm determines (and the Company so notifies the Holders of Registrable Securities) that in its judgment, such registration and offering would materially interfere with any financing, acquisition, corporate reorganization or other material transaction involving the Company that prior to such request the Board of Directors of the Company had agreed by resolution to pursue. (iv) Intentionally Omitted. (v) The holders of securities that may be registered pursuant to Section 2.1 of the 1997 Stockholders' Agreement may exercise the piggy-back registration rights granted to such holders under such Section 2.1 of the 1997 Stockholders' Agreement with respect to the Demand Registration or Special Demand Registration and be included in a registration statement pertaining to such demand registration on the same terms and conditions as the Holders of the Registrable Securities requesting such registration, subject to possible reduction at the initiative of the managing underwriter or underwriters as provided in Section 2.1(a). (vi) The holders of securities that may be registered pursuant to Section 2.02 of the Enron Registration Rights Agreement may exercise the piggy-back registration rights granted to such holders under such Section 2.02 of the Enron Registration Rights Agreement with respect to the Demand Registration or Special Demand Registration and be included in a registration statement pertaining to such demand registration on the same terms and conditions as the Holders of the Registrable Securities requesting such registration subject to possible reduction at the initiative of the managing underwriter or underwriters as provided in Section 2.1(a). (vii) The Company shall be entitled to include in any registration statement filed pursuant to this Section 2.2, for sale in accordance with the method of disposition specified by the requesting Holder, securities of the Company entitled to vote generally in the election of directors (or any securities convertible into or exchangeable for or exercisable for the purchase of securities so entitled generally to vote in the election of directors) (collectively, "Voting Securities") to be sold by the Company for its own account, except as and to the extent that, in the opinion of the managing underwriter (if such method of disposition shall be an underwritten public offering), such inclusion would materially jeopardize the successful marketing of the Registrable Securities to be sold. 2.3 Holdback Agreements; Requirements of Holders. (a) Restrictions on Public Sale by Holders of Registrable Securities. To the extent not inconsistent with applicable law, including insurance codes, SCF and each Holder of Registrable Securities that are included in a registration statement which registers Registrable Securities pursuant to this Agreement agree not to effect any public sale or distribution of the issue being registered or a similar security of the Company or any securities 9

convertible into or exchangeable or exercisable for such securities, during the 14 days prior to, and during the 180-day period (or such shorter period as to which the Company or any other Person is subject) beginning on, the effective date of a registration statement filed by the Company (except as part of such registration), but only if and to the extent requested in writing (with reasonable prior notice) by the managing underwriter or underwriters in the case of an underwritten public offering by the Company and/or selling stockholders of securities similar to the Registrable Securities; provided, however, that the period of time for which the Company is required to keep such registration statement which includes Registrable Securities continuously effective shall be increased by a period equal to such requested holdback period. (b) Restrictions on Public Sale by the Company. The Company agrees not to effect any public sale or distribution of any securities similar to those being registered, or any securities convertible into or exchangeable or exercisable for such securities, during the 14 days prior to, and during the 90-day period beginning on, the effective date of any registration statement in which the Holders of Registrable Securities are participating (except pursuant to such registration statement). (c) Cooperation by Holders. The offering of Registrable Securities by any Holder shall comply in all respects with the applicable terms, provisions and requirements set forth in this Agreement, and such Holder shall timely provide the Company with all information and materials required to be included in a registration statement that (a) relate to the offering, (b) are in possession of such Holder, and (c) relate to such Holder, and to take all such action as may be reasonably required in order not to delay the registration and offering of the securities by the Company. The Company shall have no obligation to include in such registration statement shares of a Holder who has failed to furnish such information which, in the written opinion of counsel to the Company, is required in order for the registration statement to be in compliance with the 1933 Act. 2.4 Registration Procedures. Whenever any Registrable Securities are to be registered pursuant to Sections 2.1 or 2.2 of this Agreement, the Company will use reasonable diligence to effect the registration of such Registrable Securities in accordance with the intended method of disposition thereof as quickly as practicable. In connection with any Piggy-back Registration, Demand Registration or Special Demand Registration, the Company will as expeditiously as possible: (a) prepare and file with the Commission a registration statement which includes the Registrable Securities and use reasonable diligence to cause such registration statement to become effective; provided, however, that before filing a registration statement or prospectus or any amendments or supplements thereto, including documents incorporated by reference after the initial filing of the registration statement, the Company will furnish to the Holders of the Registrable Securities covered by such registration statement and the underwriters, if any, draft copies of all such documents proposed to be filed at least 3 Business Days prior thereto, which documents will be subject to the reasonable review of such Holders and underwriters, and the Company will not file any registration statement or amendment thereto or any prospectus or any supplement thereto (including such documents incorporated by reference) to which holders of a majority of the Registrable Securities covered by such 10

registration statement or the underwriters with respect to such Registrable Securities, if any, shall reasonably object, and will notify each Holder of the Registrable Securities of any stop order issued or threatened by the Commission in connection therewith and take all reasonable actions required to prevent the entry of such stop order or to remove it if entered; (b) prepare and file with the Commission such amendments and post-effective amendments to the registration statement as may be necessary to keep the registration statement effective for a period of not less than six months (or such shorter period which will terminate when all Registrable Securities covered by such registration statement have been sold or withdrawn, but not prior to the expiration of the 90-day period referred to in Section 4(3) of the 1933 Act and Rule 174 thereunder, if applicable); cause the prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the 1933 Act; and comply with the provisions of the 1933 Act applicable to it with respect to the disposition of all securities covered by such registration statement during the applicable period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement or supplement to the prospectus; (c) furnish to any Holder of Registrable Securities included in such registration statement and the underwriter or underwriters, if any, without charge, such number of conformed copies of the registration statement and any post-effective amendment thereto and such number of copies of the prospectus (including each preliminary prospectus) and any amendments or supplements thereto, and any documents incorporated by reference therein, as such Holder or underwriter may reasonably request in order to facilitate the disposition of the Registrable Securities being sold by such Holder (it being understood that the Company consents to the use of the prospectus and any amendment or supplement thereto by each Holder of Registrable Securities covered by the registration statement and the underwriter or underwriters, if any, in connection with the offering and sale of the Registrable Securities covered by the prospectus or any amendment or supplement thereto); (d) notify each Holder of Registrable Securities included in such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, when the Company becomes aware of the happening of any event as a result of which the prospectus included in such registration statement (as then in effect) contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements therein (in the case of the prospectus or any preliminary prospectus, in light of the circumstances under which they were made) not misleading and, as promptly as practicable thereafter, prepare and file with the Commission and furnish a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; (e) use reasonable diligence to cause all Registrable Securities included in such registration statement to be listed, by the date of the first sale of Registrable Securities pursuant to such registration statement, on each securities exchange (including, for this purpose, NASDAQ Stock Market) on which the Common Stock of the Company is then listed or proposed 11

to be listed, if any and, in the case of a Special Demand Registration, use all reasonable diligence to cause all Registrable Securities included in such registration statement to be listed on the New York Stock Exchange, the American Stock Exchange or the NASDAQ Stock Market's National Market System. (f) make generally available to its security holders an earnings statement satisfying the provisions of Section 11(a) of the 1933 Act no later than 45 days after the end of the 12-month period beginning with the first day of the Company's first fiscal quarter commencing after the effective date of the registration statement, which earnings statement shall cover said 12-month period, which requirement will be deemed to be satisfied if the Company timely files complete and accurate information on Forms 10-Q, 10-K and 8-K under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and otherwise complies with Rule 158 under the 1933 Act as soon as feasible; (g) make every reasonable effort to obtain the withdrawal of any order suspending the effectiveness of the registration statement at the earliest possible moment; (h) if requested by the managing underwriter or underwriters or any Holder of Registrable Securities covered by the registration statement, promptly incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or underwriters or such Holder requests to be included therein, including, without limitation, with respect to the number of Registrable Securities being sold by such Holder to such underwriter or underwriters, the purchase price being paid therefor by such underwriter or underwriters and any other terms of the underwritten offering of such Registrable Securities, and promptly make all required filings of such prospectus supplement or post-effective amendment; (i) as promptly as practicable after filing with the Commission of any document which is incorporated by reference into a registration statement, deliver a copy of such document to each Holder of Registrable Securities covered by such registration statement; (j) on or prior to the date on which the registration statement is declared effective, use reasonable diligence to register or qualify, and cooperate with the Holders of Registrable Securities included in such registration statement, the underwriter or underwriters, if any, and their counsel, in connection with the registration or qualification of the Registrable Securities covered by the registration statement for offer and sale under the securities or blue sky laws of each state and other jurisdiction of the United States as any such Holder or underwriter reasonably requests in writing, to use reasonable diligence to keep each such registration or qualification effective, including through new filings, or amendments or renewals, during the period such registration statement is required to be kept effective and to do any and all other acts or things necessary or advisable to enable the disposition in all such jurisdictions of the Registrable Securities covered by the applicable registration statement; provided that the Company will not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject; 12

(k) cooperate with the Holders of Registrable Securities covered by the registration statement and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing securities to be sold under the registration statement, and enable such securities to be in such denominations and registered in such names as the managing underwriter or underwriters, if any, or such Holders may request, subject to the underwriters' obligation to return any certificates representing securities not sold; (l) use reasonable diligence to cause the Registrable Securities covered by the registration statement to be registered with or approved by such other governmental agencies or authorities within the United States as may be necessary to enable the seller or sellers thereof or the underwriter or underwriters, if any, to consummate the disposition of such securities; (m) enter into such customary agreements (including an underwriting agreement in customary form) and take all such other reasonable actions as the Holders of a majority of the Registrable Securities being sold or the underwriters retained by Holders participating in an underwritten public offering, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities; (n) make available for inspection by one representative of the Holders of Registrable Securities included in such Registration Statement, any underwriter participating in any disposition pursuant to such registration statement, and any attorney, accountant or other agent retained by any such representative of the Holders or underwriter (collectively, the "Inspectors"), all nonconfidential financial and other records, pertinent corporate documents and properties of the Company (collectively, the "Records"), as shall be reasonably necessary to enable each of the foregoing to exercise its due diligence responsibility, and cause the Company's officers, directors and employees to supply all Records reasonably requested by any such Inspector in connection with such registration statement; provided, however, that with respect to any Records that are confidential, the Inspectors shall execute such confidentiality agreements as the Company may reasonably request in order to maintain the confidentiality of the Records; and (o) use reasonable diligence in connection with any underwritten offering to obtain a "cold comfort" letter from the Company's independent public accountants in customary form and covering such matters of the type customarily covered by cold comfort letters as the managing underwriter or underwriters may reasonably request. Each Holder, upon receipt of any notice from the Company of the happening of any event of the kind described in subsection (d) of this Section 2.4, will forthwith discontinue disposition of the Registrable Securities until such Holder's receipt of the copies of the supplemented or amended prospectus contemplated by subsection (d) of this Section 2.4 or until it is advised in writing (the "Advice") by the Company that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings which are incorporated by reference in the prospectus, and, if so directed by the Company, such Holder will, or will request the managing underwriter or underwriters, if any, to, deliver to the Company (at the Company's 13

expense) all copies, other than permanent file copies then in such Holder's possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. In the event the Company shall give any such notice, the time periods mentioned in subsection (b) of this Section 2.4 shall be extended by the number of days during the period from and including the date of the giving of such notice to and including the date when each seller of Registrable Securities covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by subsection (d) of this Section 2.4 hereof or the Advice. If such registration statement refers to any Holder by name or otherwise as the Holder of any securities of the Company then such Holder shall have the right to require (i) the insertion therein of language, in form and substance satisfactory to such holder, to the effect that the holding by such Holder of such securities is not to be construed as a recommendation of such Holder of the investment quality of the Company's securities covered thereby and that such holding does not imply that such Holder will assist in meeting any future financial requirements of the Company, or (ii) in the event that such reference to such Holder by name or otherwise is not required by the 1933 Act or any similar federal statute then in force, the deletion of the reference to such Holder. 2.5 Expenses. (a) Registration Expenses. "Registration Expenses" means all expenses incurred by the Company incident to the Company's performance of or compliance with this Agreement, including without limitation, all SEC and securities exchange, NASDAQ or National Association of Securities Dealers, Inc. registration and filing fees, fees and expenses (other than the pro rata portion of filing fees required by state law attributable to the securities to be sold) of compliance with securities or blue sky laws (including fees and disbursements, if any, of any underwriters' counsel in connection with blue sky qualifications of the Registrable Securities), rating agency fees, printing expenses, messenger and delivery expenses, internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the fees and expenses incurred in connection with the listing of the securities to be registered on each securities exchange or NASDAQ on which similar securities issued by the Company are to be or are then listed and fees and disbursements of counsel for the Company and its independent certified public accountants (including the expenses of any special audit or "cold comfort" letters required by or incident to such performance), securities act liability insurance (if the Company elects to obtain such insurance), the fees and expenses of any special experts retained by the Company in connection with such registration and reasonable fees of one counsel for all selling Holders (the "Sellers' Attorney") (but not including any Selling Expenses). "Selling Expenses" means all underwriting fees, discounts and selling commissions allocable to the sale of Registrable Securities sold pursuant to the applicable registration statement and all out-of-pocket expenses incurred directly by the selling Holders, including for legal counsel other than the Sellers' Attorney. (b) The Company will pay all Registration Expenses in connection with each Demand Registration, Special Demand Registration or Piggyback Registration and the selling Holders shall pay all Selling Expenses. 14

2.6 Indemnification; Contribution. (a) Indemnification by the Company. The Company agrees to indemnify and hold harmless each Holder of Registrable Securities, its officers, directors and each Person who controls such Holder (within the meaning of the 1933 Act), and any Agent (as hereinafter defined) or investment advisor thereof against all Liabilities arising out of or based upon any untrue or alleged untrue statement of material fact contained in any registration statement, any amendment or supplement thereto, any prospectus or preliminary prospectus or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as any such Liabilities arise out of or are based upon any untrue statement or omission based upon information with respect to such indemnified Person furnished in writing to the Company by such indemnified Person expressly for use therein. In connection with an underwritten offering, the Company will indemnify the underwriters thereof, their officers and directors and each Person who controls such underwriters (within the meaning of the 1933 Act) to the same extent as provided above with respect to the indemnification of the Holders of Registrable Securities or to such other extent as the Company and such underwriters may agree. For purposes of this Section 2.6(a), an "Agent" of a Holder of Registrable Securities is any person acting for or on behalf of such Holder with respect to the holding or sale of such Registrable Securities. (b) Indemnification by Holders of Registrable Securities. In connection with any registration statement in which a Holder of Registrable Securities is participating, each such Holder will furnish to the Company in writing such information with respect to the name and address of such Holder and the amount of Registrable Securities held by such Holder and such other information as the Company shall reasonably request for use in connection with any such registration statement or prospectus, and agrees to indemnify, to the extent permitted by law, the Company, its directors and officers and each Person who controls the Company (within the meaning of the 1933 Act) against any Liabilities resulting from any untrue statement of a material fact or any omission of a material fact required to be stated in the registration statement or prospectus or any amendment thereof or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the extent, that such untrue statement or omission was made in reliance upon and in conformity with information with respect to such Holder so furnished in writing by such Holder specifically for inclusion in any prospectus or registration statement. In no event shall the liability of any selling Holder of Registrable Securities hereunder be greater in amount than the dollar amount of the proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation. (c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder agrees to give prompt written notice to the indemnifying party after the receipt by such Person of any written notice of the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which such Person may claim indemnification or contribution pursuant to this Agreement and, unless in the written opinion of counsel for such indemnified party a conflict of interest may exist between such indemnified party and the indemnifying party with respect to such claim, permit the indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to such indemnified party. 15

Whether or not such defense is assumed by the indemnifying party, the indemnifying party will not be subject to any liability for any settlement made without its consent. No indemnifying party will consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. If the indemnifying party is not entitled to, or elects not to, assume the defense of a claim, it will not be obligated to pay the fees and expenses of more than one counsel with respect to such claim, unless in the opinion of counsel for any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of such additional counsel or counsels. (d) Contribution. If the indemnification provided for in this Section 2.6 from the indemnifying party is unavailable to or insufficient to hold harmless an indemnified party hereunder in respect of any Liabilities referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Liabilities in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified parties in connection with the actions which resulted in such Liabilities, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified parties shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact, has been made by, or relates to information supplied by, such indemnifying party or indemnified parties, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Liabilities referred to above shall be deemed to include, subject to the limitations set forth in Section 2.6(c), any legal or other fees or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 2.6(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 2.6(d), no selling Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities of such selling Holder were offered to the public exceeds the amount of any damages which such selling Holder has otherwise been required to pay by reason of such untrue statement or omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The obligations of the Company pursuant to this Section 2.6 shall be further subject to such additional express agreements of the Company as may be required to facilitate an underwritten offering, provided that no such agreement shall in any way limit the rights of the Holders of Registrable Securities under this Agreement, or create additional obligations of such Holders not set forth herein, except as otherwise expressly agreed in writing by any such Holders. 16

2.7 Participation in Underwritten Registrations. No Holder of Registrable Securities may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder's securities on the terms of and on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements (which shall be the Company in the case of an offering of securities by the Company); (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements; and (c) agrees to be bound by all terms and conditions of this Agreement. Section 3. Other Registration Rights. The Company may only grant registration rights to any Person (including the Holders of Registrable Securities) with respect to any securities of the Company that are granted in accordance with the terms of this Section 3. Such new rights must either (i) if identical to those granted herein (through being designated as "Purchaser Shares" hereunder), be approved in writing by Holders of a majority of the then Registrable Securities, or (ii) if not identical to those granted herein, nevertheless not be inconsistent with the terms of this Agreement while providing that (a) with respect to demand registration rights granted to other Persons, the Holders of Registrable Securities have a piggy-back right upon the exercise of such new rights and shall be included in such registration statement on the same terms and conditions as the holders of the new rights, subject to possible reduction at the initiative of the managing underwriter or underwriters on terms substantially equivalent to those set forth in Section 2.1 and with respect to piggy-back rights granted to other Persons, such other Persons' rights to be included in a registration statement shall not be superior to the rights of the Holder. The Company may grant registration rights that would permit any person the right to piggy-back or may itself exercise the right to piggy-back on any Demand Registration or Special Demand Registration, provided that if the managing underwriter or underwriters of such offering delivers an opinion to the Holders of Registrable Securities that the total amount of securities which they and the holders of such new piggy-back rights intend to include in any Demand Registration or Special Demand Registration is so large as to materially and adversely affect the success of such offering (including the price at which such securities can be sold), then only the amount or kind of securities to be offered for the account of holders of such new piggy-back rights, or the Company if it is exercising piggy-back rights, will be reduced to the extent necessary to reduce the total amount of securities to be included in such offering to the amount recommended by the managing underwriter prior to any reduction in the amount of Registrable Securities to be included; and further provided that if such offering is not underwritten, then such piggy-back shall only be exercised with the consent of the Holders of a majority of the Registrable Securities being offered in the Demand Registration or Special Demand Registration. Section 4. Miscellaneous. 4.1 Recapitalizations, Exchanges, etc. The provisions of this Agreement shall apply, to the full extent set forth herein with respect to the Registrable Securities, to any and all shares of capital equity of the Company or any successor or assign of the Company (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for, or in substitution of the shares of Registrable Securities, in each case as the 17

amounts of such securities outstanding are appropriately adjusted for any equity dividends, splits, reverse splits, combinations, recapitalizations and the like occurring after the date of this Agreement. 4.2 Opinions. When any legal opinion is required to be delivered hereunder, such opinion may contain such qualifications as may be customary or otherwise appropriate for legal opinions in similar circumstances. 4.3 Notices.

The parties agree that in the event there is any breach or asserted breach of the terms, covenants or conditions of this Agreement, the remedy of the parties hereto shall be at law and in equity and injunctive relief shall lie for the enforcement of or relief from any provisions of this Agreement. 4.7 Severability.

In any case, the remaining provisions of this Agreement or the application thereof to any Person or circumstances other than those to which they have been held invalid or unenforceable, shall remain in full force and effect. 4.8 Counterparts.

Hornbeck and Troy A. Hornbeck. Unless otherwise provided herein, the provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto (including those Holders who elect to participate in any registration) and their respective heirs, legal representatives, successors and permitted assigns, and is not intended to confer upon any other Person any right or remedies hereunder other than purchasers in the Private Placement. 4.11 Entire Agreement.

EXHIBIT 4.5 AGREEMENT CONCERNING REGISTRATION RIGHTS This Agreement Concerning Registration Rights (the "Agreement") is entered into and made effective as of October 27, 2000 by and between HORNBECK-LEEVAC Marine Services, Inc., a Delaware corporation (the "Company"), SCF-IV, L.P., a Delaware limited partnership ("SCF"), JOINT ENERGY DEVELOPMENT INVESTMENTS II LIMITED PARTNERSHIP, a Delaware limited partnership, ("JEDI-II"), SUNDANCE ASSETS, L.P., a Delaware limited partnership, as successor-in-interest to Enron Capital Trade & Resources Corp. ("Sundance"), Todd M. Hornbeck, Troy A. Hornbeck (collectively, Todd and Troy Hornbeck are referred to as the "Hornbecks") and CARI INVESTMENT COMPANY, a Louisiana corporation ("Cari"). WHEREAS, the Company and SCF are entering into that certain Registration Rights Agreement dated of even date herewith (the "2000 Agreement") that provides for demand registration rights and piggy-back registration rights on behalf of SCF and certain other persons; and WHEREAS, the Company, JEDI-II and Sundance are parties to that certain Registration Rights Agreement dated June 5, 1998 (the "1998 Agreement"), that provides for demand registration rights and piggy-back registration rights on behalf of JEDI-II and Sundance, respectively; and WHEREAS, the Company, the Hornbecks and Cari are parties to that certain Stockholders' Agreement dated June 5, 1997 (the "1997 Agreement," and together with the 1998 Agreement and the 2000 Agreement, the "RRAs"), that provides for demand registration rights and piggy-back registration rights on behalf of the Hornbecks and Cari and certain other persons; and WHEREAS, SCF, JEDI-II, Sundance, the Hornbecks and Cari (each individually a "Party," and collectively, the "Parties") desire to set forth certain agreements concerning their respective rights in the event the Company files a registration statement. NOW, THEREFORE, in consideration of the mutual covenants herein contained and for other good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement agree as follows: 1. Notwithstanding the terms and conditions contained in the individual RRAs, any Party electing to participate in a registration as described herein agrees to be bound by the terms and conditions of this Agreement; provided however, that nothing in this Agreement shall derogate from or modify the terms and conditions set forth in the Stockholders' and Warrantholders' Agreement dated June 5, 1998 among the Company and the other parties thereto.

2. If the Company proposes to file a registration statement under the Securities Act of 1933, as amended, with respect to an offering by the Company for its own account, or in response to a demand by any of the Parties under any provision of the RRAs, of any class of equity security, including any securities convertible into or exchangeable for any equity security (other than a registration statement on Forms S-4 or S-8 (or their successor forms) or filed in connection with an exchange offer or an offering of securities solely to the Company's existing stockholders), then the Company shall in each case give written notice of such proposed filing to the Parties and other "Holders" of "Registrable Securities," as such terms are defined under each of the RRAs, at least twenty (20) days before the anticipated filing date, and such notice shall offer such Parties and other Holders the opportunity to register such number of Registrable Securities as each such Party or other Holder may request (a "Piggy-back Registration"). Upon notice from the Company to each of the Parties or other Holders, each Party or other Holder may request a Piggy-back Registration. In accordance with each of the RRAs, the Company shall use commercially reasonable efforts to cause the managing underwriter or underwriters of a proposed underwritten offering to permit the Parties and other Holders of Registrable Securities requested to be included in the registration for such offering to include such securities in such offering on the same terms and conditions as any similar securities of the Company or the Party who demanded registration under one of the RRAs. Notwithstanding the foregoing, if the managing underwriter or underwriters of such offering delivers a written opinion to the Company and the Parties that the total amount of securities which the Company and the Parties and any other Holders intend to include in such offering is sufficiently large to materially and adversely affect the success of such offering, then the amount of Registrable Securities to be offered shall be reduced in accordance with Section 3 hereof. 3. In the event of a registration initiated pursuant to the exercise of any demand registration rights, whether by a Party or a third party, then (i) any securities to be registered by any person or entity who is not a "Holder" under any RRA (other than the party exercising their demand rights) shall be reduced first, (ii) any securities to be registered by the Company shall then be reduced prior to effecting any reduction in the number of securities to be registered by the Parties and the other Holders and (iii) any further reduction required shall be made pro-rata among the Parties and the other Holders in proportion to the number of Registrable Securities for which they requested registration. In the event of a registration not initiated pursuant to the exercise of any demand registration rights (such as a Company-initiated registration or a "Company Registration" as contemplated by the 1997 Agreement and the 2000 Agreement) then (i) any securities to be offered by any person or entity other than a Party, any other Holder or the Company shall be reduced first, (ii) any further reduction required shall be made pro-rata among the Parties and the other Holders in proportion to the number of shares of Registrable Securities for which they requested registration, and (iii) any further reduction required shall be made with respect to the securities to be registered by the Company. The total amount of the reduction shall be the amount which the managing underwriter reasonably believes is necessary so as not to materially and adversely affect the success of the offering. 4. Notwithstanding Section 3 hereof, if any RRA is modified in a manner that increases the number or kind of securities subject to registration, then with respect to the 2

reductions to be effected among the Parties and the other Holders, such additional securities shall be the first to be excluded from registration when reductions are effected. 5. The provisions of this Agreement shall be binding upon and inure to the benefit of the Parties, the Company and those other Holders who elect to exercise any rights hereunder or to participate in any registration of Company securities and upon their respective heirs, legal representatives, successors and assigns, and is not intended to confer upon any other Person any right or remedies hereunder. 6. This Agreement, together with the other agreements referenced herein, constitutes the entire agreement and supersedes all prior agreements, understandings, both written and oral, among the parties with respect to the subject matter hereof. 7. Notwithstanding anything else in this Agreement, this Agreement will only become effective and binding on the parties hereto upon the closing of the sale by the Company of 8,150,944 shares of the Company's common stock to SCF as part of a private placement of up to $35,000,000 in common stock.

EXHIBIT 10.9 INDEMNIFICATION AGREEMENT THIS AGREEMENT (the "Agreement") is made and entered into this _____ day of __________, 2002 between Hornbeck Offshore Services, Inc., a Delaware corporation ("the Company") and __________ ("Indemnitee"). WITNESSETH THAT: WHEREAS, Indemnitee performs a valuable service for the Company; and WHEREAS, the Board of Directors of the Company has adopted Bylaws (the "Bylaws") providing for the indemnification of the directors, executive officers and other key employees of the Company to the maximum extent authorized by Section 145 of the Delaware General Corporation Law, as amended (the "DGCL"); and WHEREAS, the Board of Directors has determined that for purposes of indemnification protection afforded by the Company, including as specifically used in this Agreement, the term "director" shall refer to members of the Board of Directors and any advisory director serving by appointment of the Board; and WHEREAS, the Second Amended Bylaws (the "Bylaws") and the DGCL by their nonexclusive nature, permit contracts between the Company and the directors and officers of the Company with respect to indemnification of such directors and officers; and WHEREAS, in accordance with the authorization as provided by the DGCL, the Company may purchase and maintain a policy or policies of director's and officer's liability insurance ("D & O Insurance"), covering certain liabilities which may be incurred by its directors and/or officers in the performance of their obligations as directors and/or officers of the Company; and WHEREAS, as a result of recent developments affecting the terms, scope and availability of D & O Insurance, there exists general uncertainty as to the extent of protection afforded Company directors and officers by such D & O Insurance and said uncertainty also exists under statutory and bylaw indemnification provisions; and WHEREAS, in recognition of past services and in order to induce Indemnitee to continue to serve as a director and/or officer of the Company, the Company has determined and agreed to enter into this contract with Indemnitee; NOW, THEREFORE, in consideration, of Indemnitee's service as a director and/or officer after the date hereof, the parties hereto agree as follows; 1. INDEMNITY OF INDEMNITEE. The Company hereby agrees to hold harmless and indemnify Indemnitee to the full extent authorized or permitted by the provisions of the DGCL, as such may be amended from time to time, and Section 6.10 of the Bylaws, as such may be amended. In furtherance of the foregoing indemnification, and without limiting the generality thereof: (a) Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this Section 1(a) if, by reason of his PAGE 1

Corporate Status (as hereinafter defined), he is, or is threatened to be made, a party to or participant in any Proceeding (as hereinafter defined) other than a Proceeding by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses (as hereinafter defined), judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with such Proceeding or any claim, issue or matter therein, if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company and, with respect to any criminal Proceeding, had no reasonable cause to believe his conduct was unlawful. (b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this Section 1(b) if, by reason of his Corporate Status, he is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the Company to procure a judgment in its favor. Pursuant to this Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by him or on his behalf in connection with such Proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company; provided, however, that, if applicable law so provides, no indemnification against such Expenses shall be made in respect of any claim, issue or matter in such Proceeding as to which Indemnitee shall have been adjudged to be liable to the Company unless and to the extent that the Court of Chancery of the State of Delaware, or the court in which such Proceeding shall have been brought or is pending, shall determine that such indemnification may be made. (c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, he shall be indemnified to the maximum extent permitted by law against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him or on his behalf in connection with each successfully resolved claim, issue or matter. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 2. ADDITIONAL INDEMNITY. (a) Subject only to the exclusions set forth in Section 2(b) hereof, the Company hereby further agrees to hold harmless and indemnify Indemnitee against any and all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee in connection with any Proceeding (including an action by or on behalf of the Company) to which Indemnitee is, was or at any time becomes a party, or is threatened to be made a party, by reason of his Corporate Status; provided, however, that with respect to actions by or on behalf of the Company, indemnification of Indemnitee against any judgments shall be made by the Company only as authorized in the specific case upon a determination that Indemnitee acted in PAGE 2

good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company; and (b) No indemnity pursuant to this Section 2 shall be paid by the Company: (i) In respect to remuneration paid to Indemnitee if it shall be determined by a final judgment or other final adjudication that such remuneration was in violation of law; (ii) On account of any suit in which judgment is rendered against Indemnitee for an accounting of profits made from the purchase or sale by Indemnitee of securities of the Company pursuant to the provisions of Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto or similar provisions of any federal, state or local statutory law; (iii) On account of Indemnitee's conduct which is finally adjudged to have been knowingly fraudulent or deliberately dishonest, or to constitute willful misconduct; or (iv) If a final decision by a court having jurisdiction in the matter shall determine that such indemnification is not lawful. 3. CONTRIBUTION. If the indemnification provided in Sections 1 and 2 is unavailable and may not be paid to Indemnitee for any reason other than those set forth in paragraphs (i), (ii), (iii) and (iv) of Section 2(b), then in respect to any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding), the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in such proportion as is appropriate to reflect (i) the relative benefits received by the Company on the one hand and by the Indemnitee on the other hand from the transaction from which such Proceeding arose, and (ii) the relative fault of the Company on the one hand and of the Indemnitee on the other hand in connection with the events which resulted in such Expenses, judgments, fines or settlement amounts, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and of the Indemnitee on the other hand shall be determined by reference to, among other things, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent the circumstances resulting in such Expenses, judgments, fines or settlement amounts. The Company agrees that it would not be just and equitable if contribution pursuant to this Section 3 were determined by pro rata allocation or any other method of allocation which does not take account of the foregoing equitable considerations. 4. INDEMNIFICATION FOR EXPENSES OF A WITNESS. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his Corporate Status, a witness in any Proceeding to which Indemnitee is not a party, he shall be indemnified against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. 5. ADVANCEMENT OF EXPENSES. The Company shall advance all reasonable Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee's Corporate Status within 10 days after the receipt by the Company of a statement or statements from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee and shall include or be preceded or Page 3

accompanied by an undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that Indemnitee is not entitled to be indemnified against such Expenses. Any advances and undertakings to repay pursuant to this Section 5 shall be unsecured and interest free. Notwithstanding the foregoing, the obligation of the Company to advance Expenses pursuant to this Section 5 shall be subject to the condition that, if, when and to the extent that the Company determines that Indemnitee would not be permitted to be indemnified under applicable law, the Company shall be entitled to be reimbursed, within 30 days of such determination, by Indemnitee (who hereby agrees to reimburse the Company) for all such amounts theretofore paid; provided, however, that if Indemnitee has commenced or thereafter commences legal proceedings in a court of competent jurisdiction to secure a determination that Indemnitee should be indemnified under applicable law, any determination made by the Company that Indemnitee would not be permitted to be indemnified under applicable law shall not be binding and Indemnitee shall not be required to reimburse the Company for any advance of Expenses until a final judicial determination is made with respect thereto (as to which all rights of appeal therefrom have been exhausted or lapsed). 6. PROCEDURE FOR DETERMINATION OF ENTITLEMENT TO INDEMNIFICATION. (a) To obtain indemnification (including, but not limited to, the advancement of Expenses and contribution by the Company) under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board of Directors in writing that Indemnitee has requested indemnification. (b) Upon written request by Indemnitee for indemnification pursuant to the first sentence of Section 6(a) hereof, a determination, if required by applicable law, with respect to Indemnitee's entitlement thereto shall be made in the specific case: (i) if a Change in Control (as hereinafter defined) shall have occurred, by Independent Counsel (as hereinafter defined) in a written opinion to the Board of Directors, a copy of which shall be delivered to Indemnitee (unless Indemnitee shall request that such determination be made by the Board of Directors or the stockholders, in which case the determination shall be made in the manner provided in Clause (ii) below), or (ii) if a Change in Control shall not have occurred, (A) by the Board of Directors by a majority vote of a quorum consisting of Disinterested Directors (as hereinafter defined), or (B) if a quorum of the Board of Directors consisting of Disinterested Directors is not obtainable or, even if obtainable, said Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board of Directors, a copy of which shall be delivered to Indemnitee, or (C) if so directed by said Disinterested Directors, by the stockholders of the Company; and, if it is determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within 10 days after such determination. Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee's entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such Page 4

determination. Any Independent Counsel, member of the Board of Directors, or stockholder of the Company shall act reasonably and in good faith in making a determination under the Agreement of the Indemnitee's entitlement to indemnification. Any costs or expenses (including attorneys' fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee's entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. (c) If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 6(b) hereof, the Independent Counsel shall be selected as provided in this Section 6(c). If a Change in Control shall not have occurred, the Independent Counsel shall be selected by the Board of Directors, and the Company shall give written notice to Indemnitee advising him of the identity of the Independent Counsel so selected. If a Change in Control shall have occurred, the Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection be made by the Board of Directors, in which event the preceding sentence shall apply), and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected. In either event, Indemnitee or the Company, as the case may be, may, within 10 days after such written notice of selection shall have been given, deliver to the Company or to Indemnitee, as the case may be, a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of "Independent Counsel" as defined in Section 14 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If a written objection is made and substantiated, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If, within 20 days after submission by Indemnitee of a written request for indemnification pursuant to Section 6(a) hereof, no Independent Counsel shall have been selected, or Independent Counsel has been selected and objected to, and such objection has not been resolved, either the Company or Indemnitee may petition the Court of Chancery of the State of Delaware or other court of competent jurisdiction for resolution of any objection which shall have been made by the Company or Indemnitee to the other's selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 6(b) hereof. The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to Section 6(b) hereof, and the Company shall pay all reasonable fees and expenses incident to the procedures of this Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 8 of this Agreement, Independent Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). (d) The Company shall not be required to obtain the consent of the Indemnitee to the settlement of any Proceeding which the Company has undertaken to defend if the Company Page 5

assumes full and sole responsibility for such settlement and the settlement grants the Indemnitee a complete and unqualified release in respect of the potential liability. 7. PRESUMPTIONS AND EFFECT OF CERTAIN PROCEEDINGS. (a) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 6(a) of this Agreement, and the Company shall have the burden of proof to overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to that presumption. (b) If the person, persons or entity empowered or selected under Section 6 of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within 30 days after receipt by the Company of the request therefore, the requisite determination of entitlement to indemnification shall be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee's statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 30-day period may be extended for a reasonable time, not to exceed an additional fifteen (15) days, if the person, persons or entity making the determination with respect to entitlement to indemnification in good faith requires such additional time for obtaining or evaluating documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 7(b) shall not apply (i) if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 6(b) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination the Board of Directors or the Disinterested Directors, if appropriate, resolve to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat, or (B) a special meeting of stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is made thereat, or (ii) if the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 6(b) of this Agreement. (c) The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement (with or without court approval), conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his conduct was unlawful. (d) For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if a majority of Disinterested Directors, the stockholders, or Independent Counsel through a written opinion determines that such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company, and Page 6

in the case of a criminal proceeding, such person had no reasonable cause to believe his conduct was unlawful. In addition, the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. The provisions of this Section 7(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which the Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement. 8. REMEDIES OF INDEMNITEE. (a) In the event that (i) a determination is made pursuant to Section 6 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to indemnification shall have been made pursuant to Section 6(b) of this Agreement within 90 days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Section 3 or 4 of this Agreement within 10 days after receipt by the Company of a written request therefore, or (v) payment of indemnification is not made within 10 days after a determination has been made that Indemnitee is entitled to indemnification or such determination is deemed to have been made pursuant to Section 6 or 7 of this Agreement, Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other court of competent jurisdiction, of his entitlement to such indemnification. Alternatively, Indemnitee, at his option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 8(a). The Company shall not oppose Indemnitee's right to seek any such adjudication or award in arbitration. (b) In the event that a determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 8 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that adverse determination. (c) If a determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 8, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee's statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. (d) In the event that Indemnitee, pursuant to this Section 8, seeks a judicial adjudication of or an award in arbitration to enforce his rights under, or to recover damages for breach of, this Agreement, Indemnitee shall be entitled to recover from the Company, and shall be indemnified by the Company against, any and all expenses (of the types described in the definition of Expenses in Section 14 of this Agreement) actually and reasonably incurred by him in such judicial adjudication or arbitration, but only if he prevails therein. If it shall be determined in Page 7

said judicial adjudication or arbitration that Indemnitee is entitled to receive part but not all of the indemnification sought, the expenses incurred by Indemnitee in connection with such judicial adjudication or arbitration shall be appropriately prorated. The Company shall indemnify Indemnitee against any and all expenses and, if requested by Indemnitee, shall (within 10 days after receipt by the Company of a written request therefore) advance such expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee to recover under any directors' and officers' liability insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of expenses or insurance recovery, as the case may be. (e) The Company shall be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 8 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement. 9. NON-EXCLUSIVITY; SURVIVAL OF RIGHTS; INSURANCE; SUBROGATION. (a) The rights of indemnification as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the certificate of incorporation of the Company, the Bylaws, any agreement, a vote of stockholders or a resolution of directors, or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in the DGCL, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Bylaws and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. (b) To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers, employees, or agents or fiduciaries of the Company or of any other Enterprise which such person serves at the request of the Company, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee or agent under such policy or policies. (c) In the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. Page 8

(d) The Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 10. EXCEPTION TO RIGHT OF INDEMNIFICATION AND EXPENSE ADVANCEMENT. Notwithstanding any other provision of this Agreement, Indemnitee shall not be entitled to indemnification or advancement of expenses under this Agreement with respect to any Proceeding brought by Indemnitee, or any claim therein, unless (a) the bringing of such Proceeding or making of such claim shall have been approved by the Board of Directors or (b) such Proceeding is being brought by the Indemnitee to assert his rights under this Agreement. 11. DURATION OF AGREEMENT. All agreements and obligations of the Company contained herein shall apply to the period Indemnitee is or was a director or officer of the Company, including any such period prior to this Agreement, (or the period Indemnitee is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) and shall continue thereafter so long as Indemnitee shall be subject to any Proceeding (or any proceeding commenced under Section 8 hereof) by reason of his Corporate Status, whether or not he is acting or serving in any such capacity at the time any liability or expense is incurred for which indemnification can be provided under this Agreement. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), assigns, spouses, heirs, executors and personal and legal representatives. This Agreement shall continue in effect regardless of whether Indemnitee continues to serve as a director or officer of the Company or any other Enterprise at the Company's request. 12. SECURITY. To the extent requested by the Indemnitee and approved by the Board of Directors, the Company may at any time and from time to time provide security to the Indemnitee for the Company's obligations hereunder through an irrevocable bank line of credit, funded trust or other collateral. Any such security, once provided to the Indemnitee, may not be revoked or released without the prior written consent of the Indemnitee. 13. ENFORCEMENT. (a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director or officer of the Company. (b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof. 14. DEFINITIONS. For purposes of this Agreement: (a) "Change in Control" means a change in control of the Company occurring after the date of this Agreement of a nature that would be required to be reported in response to Item 6(e) Page 9

of Schedule 14A of Regulation 14A (or in response to any similar item on any similar schedule or form) promulgated under the Securities Exchange Act of 1934 (the "Act"), whether or not the Company is then subject to such reporting requirement; provided, however, that, without limitation, such a Change in Control shall be deemed to have occurred if after the date of this Agreement (i) any "person" (as such term is used in Sections 13(d) and 14(d) of the Act, as amended) other than a trustee or other fiduciary holding securities under an employee benefit plan of the Company or a corporation owned directly or indirectly by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company, is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Act), directly or indirectly, of securities of the Company representing 20% or more of the combined voting power of the Company's then outstanding securities (other than any such person or any affiliate thereof that is such a 20% beneficial owner as of the date hereof) without the prior approval of at least two-thirds of the members of the Board of Directors in office immediately prior to such person attaining such percentage interest; (ii) there occurs a proxy contest, or the Company is a party to a merger, consolidation, sale of assets, plan of liquidation or other reorganization, as a consequence of which members of the Board of Directors in office immediately prior to such transaction or event constitute less than a majority of the Board of Directors thereafter; or (iii) during any period of two consecutive years, other than as a result of an event described in clause (a)(ii) of this Section 14, individuals who at the beginning of such period constituted the Board of Directors (including for this purpose any new director whose election or nomination for election by the Company's stockholders was approved by a vote of at least two-thirds of the directors then still in office who were directors at the beginning of such period) cease for any reason to constitute at least a majority of the Board of Directors. A Change in Control shall not be deemed to have occurred under item (i) above if the "person" described under item (i) is entitled to report its ownership on Schedule 13G promulgated under the Act and such person is able to represent that it acquired such securities in the ordinary course of its business and not with the purpose nor with the effect of changing or influencing the control of the Company, nor in connection with or as a participant in any transaction having such purpose or effect. If the "person" referred to in the previous sentence would at any time not be entitled to continue to report such ownership on Schedule 13G pursuant to Rule 13d-l(b)(3)(i)(B) of the Act, then a Change in Control shall be deemed to have occurred at such time. (b) "Corporate Status" describes the status of a person who is or was a director, officer, employee or agent or fiduciary of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise which such person is or was serving at the express written request of the Company, provided that the approval by the Board of Directors of such position in a resolution adopted by the Board of Directors shall for all purposes qualify as such a written requirement. (c) "Disinterested Director" means a director of the Company who is not and was not a party to the Proceeding in respect of which indemnification is sought by Indemnitee. (d) "Enterprise" shall mean the Company and any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise of which Indemnitee is or was serving at the express written request of the Company as a director, officer, employee, agent or fiduciary Page 10

provided that the approval by the Board of Directors of such position in a resolution adopted by the Board of Directors shall for all purposes qualify as such a written requirement. (e) "Expenses" shall include all reasonable attorneys' fees, retainers, court costs, transcript costs, fees of experts, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees, and all other disbursements or expenses of the types customarily incurred in connection with prosecuting, defending, preparing to prosecute or defend, investigating, participating, or being or preparing to be a witness in a Proceeding. (f) "Independent Counsel" means a law firm, or a member of a law firm, that is experienced in matters of corporation law and neither presently is, nor in the past five years has been, retained to represent the Company or Indemnitee in any matter material to either such party (other than with respect to matters concerning the Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements) or any other party to the Proceeding giving rise to a claim for indemnification hereunder, or otherwise has any substantial business or personal relationship with the Company or Indemnitee or any other party to the Proceeding giving rise to a claim for indemnification hereunder that could reasonably be considered to influence the independent judgment of the Independent Counsel. Notwithstanding the foregoing, the term "Independent Counsel" shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee's rights under this Agreement. The Company agrees to pay the reasonable fees of the Independent Counsel referred to above and to fully indemnify such counsel against any and all expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. (g) "Proceeding" includes any threatened, pending or completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought by or in the right of the Company or otherwise and whether civil, criminal, administrative or investigative, in which Indemnitee was, is or will be involved as a party or otherwise, by reason of Indemnitee's Corporate Status, by reason of any action taken by him or of any inaction on his part while acting as a director or officer of the Company, or by reason of the fact that he is or was serving as a director, officer, employee or agent of another Enterprise at the request of the Company, in each case whether or not he is acting or serving in any such capacity at the time any liability or expense is incurred for which indemnification can be provided under this Agreement; including one pending on or before the date of this Agreement and excluding one initiated by an Indemnitee pursuant to Section 8 of this Agreement to enforce his rights under this Agreement. 15. SEVERABILITY. If any provision or provisions of this Agreement shall be held by a court of competent jurisdiction to be invalid, void, illegal or otherwise unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; and (b) to the fullest extent possible, Page 11

the provisions of this Agreement (including, without limitation, each portion of any section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested thereby. 16. MODIFICATION AND WAIVER. No supplement, modification, termination, waiver or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver. 17. NOTICE BY INDEMNITEE. Indemnitee agrees promptly to notify the company in writing upon being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification covered hereunder. The failure to so notify the Company shall not relieve the Company of any obligation which it may have to the Indemnitee under this Agreement or otherwise. 18. NOTICES. All notices, requests, demands and other communications hereunder shall be in writing and shall be deemed to have been duly given if (i) delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed, or (ii) mailed by certified or registered mail with postage prepaid, on the third business day after the date on which it is so mailed: (a) If to Indemnitee, to: (b) If to the Company, to: Hornbeck Offshore Services, Inc. 414 North Causeway Boulevard Mandeville, Louisiana 70448 Attention: President and Chief Executive Officer or to such other address as may have been furnished to Indemnitee by the Company or to the Company by Indemnitee, as the case may be. 19. IDENTICAL COUNTERPARTS. This Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an original but all of which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the existence of this Agreement. 20. HEADINGS. The headings of the paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect the construction thereof. Page 12
