E-1 PART III i This Annual Report on Form 10-K contains “forward-looking statements,” as contemplated by the Private Securities Litigation Reform Act of 1995, in which the Company discusses factors it believes may affect its performance in the future. Forward-looking statements are all statements other than historical facts, such as statements regarding assumptions, expectations, beliefs and projections about future events or conditions. You can generally identify forward-looking statements by the appearance in such a statement of words like “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “remain,” “should,” or “will,” or other comparable words or the negative of such words. The accuracy of the Company’s assumptions, expectations, beliefs and projections depends on events or conditions that change over time and are thus susceptible to change based on actual experience, new developments and known and unknown risks. The Company gives no assurance that the forward-looking statements will prove to be correct and does not undertake any duty to update them. The Company’s actual future results might differ from the forward-looking statements made in this Annual Report on Form 10-K for a variety of reasons, including the effect of the de facto regulatory moratorium on the issuance of drilling and other permits in the Gulf of Mexico due to government regulations. Future results may also be impacted by proposed federal legislation or regulations that may be implemented in response to the Deepwater Horizon event. Such legislation or regulations could further aggravate a number of other existing risks, uncertainties and assumptions, including, without limitation: less than anticipated success in marketing and operating the Company’s MPSVs; bureaucratic, administrative or operating barriers that delay vessels chartered in foreign markets from going on-hire or result in contractual penalties imposed by foreign customers; further weakening of demand for the Company’s services; the inability to effectively curtail operating expenses from stacked vessels; unplanned customer suspensions, cancellations, rate reductions or non-renewals of vessel charters or failures to finalize commitments to charter vessels; industry risks; further reductions in capital spending budgets by customers; declines in oil and natural gas prices; increases in operating costs; the inability to accurately predict vessel utilization levels and dayrates; the inability to effectively compete in or operate in international markets; less than anticipated subsea infrastructure demand activity in the U.S. Gulf of Mexico and other markets; the level of fleet additions by competitors that could result in over capacity; economic and political risks, including the recent unrest in the Middle East; weather related risks; the inability to attract and retain qualified personnel; regulatory risks; the repeal or administrative weakening of the Jones Act; the imposition of laws or regulations that result in reduced exploration and production activities or that increase the Company’s operating costs or operating requirements, including any such laws or regulations that may arise as a result of the de facto regulatory moratorium or as a result of the oil spill disaster in the Gulf of Mexico; drydocking delays and cost overruns and related risks; vessel accidents or pollution incidents resulting in lost revenue or expenses that are unrecoverable from insurance policies or other third parties; unexpected litigation and insurance expenses; fluctuations in foreign currency valuations compared to the U.S. dollar and risks associated with expanded foreign operations, such as non-compliance with or the unanticipated effect of tax laws, customs laws, immigration laws, or other legislation that result in higher than anticipated tax rates or other costs or the inability to repatriate foreign-sourced earnings and profits. In addition, the Company’s future results may be impacted by adverse economic conditions, such as inflation, deflation, or lack of liquidity in the capital markets, that may negatively affect it or parties with whom it does business resulting in their non-payment or inability to perform obligations owed to the Company, such as the failure of customers to fulfill their contractual obligations or the 1 failure by individual banks to provide expected funding under the Company’s credit agreement. Should one or more of the foregoing risks or uncertainties materialize in a way that negatively impacts the Company, or should the Company’s underlying assumptions prove incorrect, the Company’s actual results may vary materially from those anticipated in its forward-looking statements, and its business, financial condition and results of operations could be materially and adversely affected. Additional factors that you should consider are set forth in detail in the “Risk Factors” section of this Annual Report on Form 10-K as well as other filings the Company has made and will make with the Securities and Exchange Commission which, after their filing, can be found on the Company’s website www.hornbeckoffshore.com.

In this Annual Report on Form 10-K, references to “company,” “we,” “us,” “our” or like terms refer to Hornbeck Offshore Services, Inc. and its subsidiaries, except as otherwise indicated. Hornbeck Offshore Services, Inc. is a leading provider of marine services to exploration and production, oilfield service, offshore construction and U.S. military customers. Since our establishment, we have primarily focused on providing innovative technologically advanced marine solutions to meet the evolving needs of the deepwater and ultra-deepwater energy industry in domestic waters and increasingly in foreign locations. Throughout our history, we have expanded our fleet of vessels primarily through a series of new vessel construction programs, as well as through acquisitions of existing vessels. We maintain our headquarters at 103 Northpark Boulevard, Suite 300, Covington, Louisiana, 70433; our telephone number is (985) 727-2000. We operate two business segments in the marine industry. Our Upstream segment owns and operates one of the youngest and largest fleets of U.S.-flagged, new generation OSVs and, we believe, one of the youngest and largest U.S.-owned fleets of DP-2 and DP-3 MPSVs. Together, these vessels support deepwater and ultra-deepwater exploration, development, production, construction, installation, maintenance, repair and enhanced oil recovery requirements of the offshore oil and gas industry, primarily in the U.S. Gulf of Mexico, or GoM, and in select international markets. While we have historically operated our Upstream segment predominately in the GoM, the recent Deepwater Horizon incident and the resulting domestic deepwater drilling regulatory environment have contributed to our increased focus on deployment of vessels to international markets. As of December 31, 2010, we had 16 new generation OSVs working in foreign markets compared to 11 new generation OSVs as of December 31, 2009. Our Upstream segment also includes six work class ROVs, a shore-base facility located in Port Fourchon, Louisiana and one inactive conventional OSV, which is considered a non-core asset. On occasion, we provide vessel management services for other vessels owners, such as crewing, daily operational management and maintenance activities. Our Downstream segment owns and operates a fleet of ocean-going tugs and double-hulled tank barges that transport petroleum products, primarily in the northeastern United States and the GoM. Although all of our vessels are capable of operating in both domestic and international waters, all but six of our vessels are qualified under Section 27 of the Merchant Marine Act of 1920, also known as the Jones Act, to engage in the U.S. coastwise trade. Foreign owned, flagged, built or crewed vessels are restricted in their ability to conduct U.S. coastwise trade and are typically excluded from such trade. We intend to continue our efforts to maximize stockholder value through our long-term return-oriented growth strategy. We will, as opportunities arise, acquire or construct additional vessels, as well as divest certain assets that we consider to be non-core or otherwise not in-line with our long-term strategy. 3 DESCRIPTION OF OUR BUSINESS Our Upstream Segment General—OSVs OSVs primarily serve exploratory and developmental drilling rigs and production facilities and support offshore and subsea construction, installation, maintenance, repair and decommissioning activities. OSVs differ from other ships primarily due to their cargo-carrying flexibility and capacity. In addition to transporting deck cargo, such as pipe or drummed material and equipment, OSVs also transport liquid mud, potable and drilling water, diesel fuel, dry bulk cement and personnel between shore bases and offshore rigs and production facilities. In the mid-1990s, oil and gas producers began seeking large hydrocarbon reserves in deeper water depths using new, specialized drilling and production equipment. We recognized that the then-existing fleet of conventional OSVs operating in the GoM was not designed to support these more complex projects or to operate in the challenging environments in which they were conducted. Therefore, in 1997, we conceived of a fleet of new generation OSVs with enhanced capabilities to allow them to more effectively support deepwater drilling and related construction projects. In order to best serve these projects, we designed our new generation vessels with larger liquid mud and dry bulk cement capacities, as well as larger areas of open deck space, which are features essential to deepwater projects that are often distant from shore-based support infrastructure. Deepwater environments also require dynamic positioning, or anchorless station-keeping capability, driven primarily by safety concerns that preclude vessels from physically mooring to deepwater installations. Such DP systems have experienced steady increases in technology over time with the highest DP rating currently being DP-3. The number following the DP notation generally indicates the degree of redundancy built into the vessel’s systems and the range of usefulness of the vessel in deepwater construction and subsea operations. Higher numbers represent greater DP capabilities. Since 1997, we have executed our business plan to serve the deepwater exploration and production requirements of our customers with our diverse fleet of new generation OSVs. With the completion of our fourth OSV newbuild program in 2010, we own a fleet of 51 new generation OSVs. Our new generation OSV fleet is comprised of a broad array of vessel classes with varying sizes and capabilities. Through a series of newbuild construction programs and multiple acquisitions, we now have a total of ten distinct new generation OSV vessel class designs particularly suited for our customers’ evolving needs. Our newest proprietary vessel design, the 250 EDF class, is based on our highly successful 240 ED design modified to lengthen the vessel and expand the propulsion package to achieve faster transit speeds. General—MPSVs MPSVs also support the offshore exploration and production activities of the energy industry. MPSVs are distinguished from OSVs in that they are significantly larger and more specialized vessels that are principally used to support complex deepwater subsea construction, installation, intervention, maintenance, repair, decommissioning and other sophisticated operations. These vessels are or can be equipped with a variety of lifting and deployment systems, including ROVs, large capacity cranes, winches or reel systems. For example, MPSVs can serve as a platform for the subsea installation of risers, jumpers and 4 umbilicals. MPSVs also support ROV operations, diving activities, oil spill response efforts, well intervention, including live well intervention, platform decommissioning and other complex construction operations. Generally, MPSVs command higher day rates than OSVs due to their significantly larger relative size and versatility, as well as higher construction and operating costs. In May 2005, we conceived of a new breed of MPSV that, in addition to the array of services described above, are also capable of being utilized to transport deck or bulk cargoes with capacities far exceeding that of even the largest new generation OSVs. We launched an innovative MPSV program to convert two former U.S.-flagged sulfur carriers into proprietary 370 class DP-2 new generation MPSVs. These MPSVs have nearly three times the deadweight and liquid mud capacity of one of our 265 class new generation OSVs and more than eight times the liquid mud capacity of one of our 200 class new generation OSVs. Moreover, these MPSVs can assist in large volume deepwater well testing and flow-back operations. In addition, these vessels can be outfitted with a variety of “tool kits” including ROVs, large capacity cranes, winches and other apparatus to support offshore construction, subsea well intervention, ROV operations, pipe-hauling, oil spill response and flotel services, among others. In May 2007, we expanded our MPSV program to include the HOS Iron Horse, which is a newbuild MPSV that was constructed at IHC Holland’s Merwede Shipyard in the Netherlands. Our MPSV program was further expanded in January 2008 with the acquisition of the HOS Achiever, which was then under construction at IHC Holland’s Krimpen Shipyard, also in the Netherlands. The HOS Iron Horse and HOS Achiever are 430 class DP-3 new generation MPSVs. A DP-3 notation requires greater vessel and ship-system redundancies. DP-3 systems also include separate vessel compartments with fire-retardant walls for generators, prime movers, switchboards and most other DP components. These 430 class MPSVs are designed to handle a variety of global offshore energy applications, many of which are not dependent on the exploratory rig count. They are excellent platforms to support subsea-to-surface construction, inspection, repair and maintenance, well intervention, oil spill response, decommissioning projects and flotel services, as well as pipeline and subsea wellhead installations with ROVs, saturation diving systems and flexible umbilical and flexible pipe-laying capabilities. They are not, however, equipped to handle liquid cargoes. The HOS Iron Horse and the HOS Achiever are not U.S.-flagged vessels, however, they can engage in certain legally permissible operations in the U.S. that do not constitute coastwise trade. 5 The following table provides information, as of February 15, 2011, regarding our Upstream fleet of 51 new generation OSVs and four MPSVs.

This vessel, the Cape Breton, is considered a non-core asset and is currently inactive and marketed for sale. (2) The BJ Blue Ray was renamed the Independence due to the BJ Services/Baker Hughes merger and the resulting vessel charter assignment to a third party. (3) The HOS Navegante, a foreign-flagged AHTS, is used primarily for its OSV capabilities. (4) In recognition of the soft Upstream market conditions that began in the second quarter of 2009, we commenced stacking certain of our new generation OSVs on various dates since May 2009. Since April 2010, the GoM has been under a government–imposed drilling moratorium, or de facto regulatory moratorium, which is expected to remain in effect to a significant degree through at least the first half of 2011. We expect to have an average of 15.0 new generation OSVs cold-stacked during 2011. In December 2005, we acquired the lease rights to a shore-base facility located in Port Fourchon, Louisiana, which we renamed HOS Port. Port Fourchon’s proximity to the deepwater GoM provides a strategic logistical advantage for servicing drilling rigs and production units. Developed as a multi-use facility, Port Fourchon has historically been a land base for offshore oil support services and the Louisiana Offshore Oil Port, or LOOP. According to industry sources, Port Fourchon services nearly all deepwater rigs and almost half of all shallow rigs in the GoM. The HOS Port facility lease has two years remaining on its initial term, with four additional five-year renewal periods. In January 2008, we purchased a leasehold interest in an additional parcel of improved real estate adjacent to HOS Port. The new facility lease has four years remaining on its initial term, with four additional five-year renewal periods. The combined acreage of the two adjoining properties now comprising HOS Port is approximately 60 acres with total waterfront bulkhead of nearly 3,000 linear feet. HOS Port not only supports our existing fleet and Upstream customers’ deepwater logistics requirements, but it underscores our long-term commitment to and our long-term outlook for the deepwater GoM, notwithstanding the current de facto regulatory moratorium. Principal Markets for Upstream Segment OSVs and MPSVs operate worldwide, but are generally concentrated in relatively few offshore regions with high levels of exploration and development activity, such as the GoM, the North Sea, Southeast Asia, West Africa, Latin America, and the Middle East. While there is some vessel migration between regions, key factors such as mobilization costs, vessel suitability and government statutes prohibiting foreign-flagged vessels from operating in certain waters, or coastwise cabotage laws such as the Jones Act, can limit the migration of OSVs. Because MPSVs are generally utilized for non-cargo operations, they are less limited by cabotage laws. Demand for OSVs, as evidenced by dayrates and utilization rates, is primarily related to offshore oil and natural gas exploration, development and production activity. Such activity is influenced by a number of factors, including the actual and forecasted price of oil and natural gas, the level of drilling permit activity, capital budgets of offshore exploration and production companies, and repair and maintenance needs in the deepwater oilfield. Our principal geographic market is the GoM, where we provide and have historically provided services to several major integrated oil companies as well as mid-size and large independent oil companies with deepwater and ultra-deepwater 7 activities. We also operate in select international markets, primarily Brazil, Mexico, Trinidad and Qatar, where we provide services to state-owned oil companies and major international oil and oilfield service companies. We are often subcontracted by other oilfield service companies, both in the GoM and internationally, to provide a new generation fleet that enables them to render offshore oilfield services, such as well stimulation or other enhanced oil recovery activities, diving and ROV operations, construction, installation, maintenance, repair and decommissioning services. Since 2006, we have also developed a specialized application of our new generation OSVs for use by the United States military. The April 20, 2010 catastrophic explosion of the Deepwater Horizon, the related oil spill in the GoM and the U.S. government’s response to those events has significantly and adversely disrupted oil and gas exploration activities in the GoM. Shortly after the explosion, the Department of the Interior (DOI) imposed a moratorium effectively suspending all deepwater drilling activity in the GoM. Although the DOI announced that it was lifting such drilling moratorium on October 12, 2010, delays in obtaining drilling permits and uncertainty surrounding compliance with new safety regulations, or a de facto regulatory moratorium, continue to slow new drilling and exploration activity by GoM operators, including operators in shallow waters. If this de facto regulatory moratorium continues for an extended period, we may need to further expand our international presence by mobilizing additional vessels out of the GoM into foreign markets such as Latin America, West Africa, the Middle East or other regions. The deployment of additional vessels to foreign markets will take time, resulting in periods in which they are not earning revenue and will require us to make expenditures necessary for such repositioning. In addition, the ability to obtain charters in international locations is not certain given the competition that exists for such charters, which may increase as more vessels depart the GoM in response to the lack of drilling permit activity. In response to the de facto regulatory moratorium, we have stacked 15 of our new generation OSVs and have taken other measures to reduce costs, such as laying off crew members and deferring certain vessel drydocking and upgrades. During the Deepwater Horizon disaster, our Upstream equipment demonstrated the breadth and depth of services that we are able to provide. Our vessels were involved in nearly every aspect of the marine services required to respond to this event. Our OSVs were employed in skimming, environmental monitoring, accommodations, as well as dispersant and other support operations. In addition, our 370 class MPSVs were selected as key assets supporting the “top-kill” and “bottom-kill” efforts, which provided our industry a platform to witness the unique capabilities of these vessels on a wide-scale. Our 430 class MPSVs, together with certain of our ROVs, were also utilized as part of the well-capping, fluid injection, fire prevention, subsea installation, and well-monitoring efforts critical to the oil spill containment effort. Our charters are the product of either direct negotiation or a competitive proposal process, which evaluates vessel capability, availability and price. Our primary method of chartering in the GoM is through direct vessel negotiations with our customers on either a long-term or spot basis. In the international market, we often charter through local entities in order to comply with cabotage or other local requirements. Some charters are solicited by customers through international vessel brokerage firms, which earn a commission that is customarily paid by the vessel owner. Our military charters are the product of a competitive procurement process conducted by the Military Sealift Command. All of our charters, whether 8 long-term or spot, are priced on a dayrate basis, whereby for each day that the vessel is under contract to the customer, we earn a fixed amount of charter-hire for making the vessel available for the customer’s use. Many long-term contracts and all government, including national oil company, charters contain early termination options in favor of the customer; however, some have fees designed to discourage early termination. Long-term charters sometimes contain provisions that permit us to increase our dayrates in order to be compensated for certain increased operational expenses or regulatory changes. Competition for Upstream Segment The OSV and MPSV industry is highly competitive. Competition primarily involves such factors as: (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) quality, capability and age of vessels; quality and capability of the crew members; ability to meet the customer’s schedule; safety record; reputation; price and; experience. All but six of our OSVs and MPSVs are U.S.-flagged vessels, which are qualified under the Jones Act to engage in domestic coastwise trade. The Jones Act restricts the ability of vessels that are foreign-built, foreign-owned, foreign-crewed or foreign-flagged from engaging in coastwise trade in the United States and Puerto Rico. The services typically provided by OSVs constitute coastwise trade as defined by the Jones Act. Consequently, competition for our Upstream services in the GoM is largely restricted to other U.S. vessel owners and operators, both publicly and privately held. We believe that we operate the second largest fleet of new generation Jones Act qualified OSVs in the United States. See “Environmental and Other Governmental Regulation” for a more detailed discussion of the Jones Act. Internationally, our OSVs compete against other U.S. owners, as well as foreign owners and operators of OSVs. Some of our international competitors may benefit from a lower cost basis in their vessels, which are not generally constructed in high-cost U.S. shipyards, as well as from lower crewing costs and favorable tax regimes. While foreign vessel owners cannot engage in U.S. coastwise trade, some cabotage laws in other parts of the world permit waivers for foreign vessels if domestic vessels are unavailable. We, and other U.S. and foreign vessel owners have been able to obtain such waivers in the foreign jurisdictions in which we operate. Many of the services provided by MPSVs do not involve the transportation of merchandise and therefore are generally not considered coastwise trade under U.S. and foreign cabotage laws. Accordingly, competition in the MPSV industry is global in nature and is more greatly affected by the particular capabilities of a vessel to meet the requirements of a customer’s project. Our 430 class MPSVs have DP-3 systems, which increase their uniqueness in the international market and their ability to support highly specialized operations for which customers require a high-end dynamic positioning solution. Our 370 class MPSVs are Jones Act-qualified DP-2 classed vessels. Unlike most MPSVs that do not 9 carry significant amounts of deck or bulk cargo, these vessels will compete for projects with other international MPSVs as well as participate in the GoM and international OSV markets as large-capacity carriers of drilling fluids, petroleum products and deck cargos in support of deepwater exploration, development and production operations. Although some of our principal competitors are larger, have greater financial resources and have more extensive international operations than we do, we believe that our operating capabilities and reputation for quality and safety enable us to compete effectively with other fleets in the market areas in which we operate and intend to operate. In particular, we believe that the relatively young age and advanced features of our OSVs and MPSVs provide us with a competitive advantage. The ages of our new generation OSVs range from less than one year to twelve years. In fact, one-third of our active new generation OSVs have been placed in service since January 1, 2008. The average age of the industry’s conventional U.S.-flagged OSV fleet is approximately 30 years. We believe that most of these older vessels are cold- stacked and many of them will be permanently retired in the next few years due to physical and economic obsolescence. Worldwide competition for new generation vessels has been impacted in recent years by the increase in newbuild OSVs placed in service, greater customer interest in deep well, deepwater and ultra-deepwater drilling activity and the U.S. government-imposed drilling moratorium and de facto regulatory moratorium in the GoM. Competition for MPSVs differs from OSVs in that MPSVs that do not have coastwise trade privileges might be permitted to operate in the GoM provided they do not engage in certain activities that are reserved for Jones Act-qualified vessels. Consequently, our U.S.-flagged DP-2 MPSVs may face more competition from foreign-flagged vessels in the GoM than do our OSVs. In addition, while operating in the GoM, our foreign-flagged DP-3 MPSVs are required to utilize U.S. crews while foreign-owned vessels are not. U.S. crews are often more expensive than foreign crews. Also, foreign MPSV owners may have more favorable tax regimes than ours. Consequently, prices for foreign-owned MPSVs in the GoM are often lower than prices we can charge. Finally, some potential MPSV customers are also owners of MPSVs that will compete with our vessels. Our OSVs, by contrast, are usually contracted by oil companies, which do not own their own vessels and therefore do not compete with us. Our Downstream Segment General The domestic tank barge industry provides marine transportation of crude oil, petroleum products and petrochemicals by ocean-going tugs and tank barges and is a critical link in the U.S. petroleum distribution chain. The largest domestic tank barge market is on the East Coast. The largest tank barge market in the northeastern United States is New York Harbor. Petroleum products are transported in the northeastern United States through a vast network of terminals, tankers and pipelines. 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, Massachusetts 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 larger petroleum tankers are being built, we believe that direct delivery into New York Harbor has favorably impacted tank barge demand for lightering services and further shipment to New England, the Hudson River and Long Island. 10 We offer marine transportation, distribution and logistics services primarily in the northeastern United States, GoM, Great Lakes and Puerto Rico with our active Downstream fleet of nine double-hulled tank barges and nine ocean-going tugs. We also own six ocean- going tugs that are stacked. We provide our services to major integrated oil companies, independent refineries and oil traders. 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”. 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. Oil Pollution Act of 1990 OPA 90 mandates that all single-hulled tank vessels operating in U.S. waters be removed from petroleum transportation service according to a set time schedule. We believe that any remaining single-hulled capacity, which is scheduled to be retired by 2015, has already been removed from service due to the soft demand and increased newbuild double- hulled tank barge capacity that has been delivered to the market over the past three years. None of our double-hulled tank barges are subject to OPA 90 retirement dates. The following tables provide information, as of February 15, 2011, regarding our Downstream fleet of 15 ocean-going tugs and 10 tank barges.

These vessels were significantly improved and (2) modernized to accommodate our newbuild double-hulled tank barges. In recognition of the soft Downstream market conditions for our single-hulled equipment that began early in the second quarter of 2008 and is expected to continue through at least the first half of 2011, we stacked six lower horsepower tugs on various dates since April 1, 2008. 11 Ocean-Going Tank Barges Name Active: Energy 13501 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

For a discussion of OPA 90, see “—Environmental and Other Governmental Regulation” below. In March 2011, we sold our last remaining single-hulled tank barge, the Energy 6504, which had been stacked since June 2008 due to soft Downstream market conditions. Principal Market for Downstream Segment Major oil companies, refining, marketing and trading companies constitute the majority of our customers for Downstream services. We enter into a variety of contract arrangements with our Downstream customers, including spot and time charters, contracts of affreightment, consecutive voyage contracts and, occasionally, bareboat charters. Our contracts are obtained through competitive bidding, or with established customers through negotiation. We sometimes place charters through the brokerage community, which charges a brokerage commission payable by us. The brokerage commissions are based on the dayrates charged to customers. Our ocean-going 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 have also transported both clean and dirty petroleum products from refineries and distribution terminals in Puerto Rico to the Puerto Rico Electric Power Authority and to utilities located on other Caribbean islands. In addition, we have provided ship lightering, bunkering and docking services in these markets and are well positioned to provide such services to the increasing number of new tankers that are too large to make direct deliveries to distribution terminals and refineries. Also, since 2005, we have accessed new markets for our double-hulled tank barges by performing upstream services for our OSV customers in the deepwater GoM. Re-deploying some of our Downstream equipment to the GoM provided additional market opportunities with new downstream customers. Our tug and tank barge fleet has also served the Great Lakes region on a seasonal basis to support increased demand for clean fuels during the summer driving season. During the post-Deepwater Horizon oil spill response efforts in the GoM, certain of our Downstream equipment was mobilized to serve as processing, collection and skimming vessels. 12 Competition for Downstream Segment In addition to pricing, which is a significant factor, the basis for competition in the Downstream industry is dependent upon four major determinants: (cid:129) Management systems: The operating capabilities of the vessels and the skill of the crews that man those vessels is a key determinant of a fleet’s ability to operate efficiently (cid:129) Scheduling: The ability of the fleet to meet stringent customer sailing and delivery schedule requirements. (cid:129) Experience: Efficient sailing schedules and lower fleet incident rates are indicative of higher safety standards and experienced personnel. (cid:129) Vessel size and accessibility to customer terminals: Customer terminals vary widely in the sizes and types of vessels than can be accepted in their berths. A Downstream operator’s market reputation is a function of its performance against each of these criteria. Our Downstream segment has built a reputation in the TTB industry for providing punctual, high quality service with a focus on safety. When analyzing our competitive landscape, we consider the blue-water, short-haul niche within the East Coast market to be our primary operating domain. In defining the East Coast, we include the entire Atlantic seaboard from the northeastern U.S. to Florida, the GoM region, Puerto Rico and the Great Lakes. The total barrel capacity of all short-haul competitors that are either headquartered or currently operating the majority of their vessels within the East Coast market is fairly evenly distributed among seven companies that own about 90% of the short-haul fleet; including the barrels that we transport. Competitors in our market niche are primarily comprised of well-established, multi-generational, family-owned businesses, with only two publicly traded companies, including us, having a critical mass of coastwise barges in the size range of 50,000 to 150,000 barrels. We do not anticipate significant competition in the near term from new “greenfield” refined products pipelines or pipeline expansions along the primary transportation routes in the northeastern U.S. or Puerto Rico. FINANCIAL INFORMATION ABOUT SEGMENTS See Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 15 to our consolidated financial statements for further discussion regarding financial information by segment and geographic location. CUSTOMER DEPENDENCY 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, 2010, BP and Military Sealift Command each accounted for more than 10% of our total revenues. For a discussion of significant customers in prior periods, see Note 13 to our consolidated financial statements. 13 GOVERNMENT REGULATION Environmental Laws and Regulations Our operations are 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 including natural resource damages associated with releases of oil or hazardous materials 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 that impose additional or more restrictive requirements 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 and/or reporting 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, as amended by the Coast Guard and Maritime Transportation Act of 2006, “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 (i) for a single-hulled vessel, the greater of $3,200 per gross ton or $23.5 million or (ii) for a tank vessel other than a single-hulled vessel, the greater of $2,000 per gross ton or $17.1 million. “Tank vessels” of 3,000 gross tons or less are subject to liability limits of (i) for a single-hulled vessel, the greater of $3,200 per gross ton or $6.4 million or (ii) for a tank vessel other than a single-hulled vessel, the greater of $2,000 per gross ton or $4.3 million. For any vessels, other than “tank vessels,” that are subject to OPA 90, the liability limits are the greater of $1,000 per gross ton or $854,400. 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. In addition, there are no liability limits for vessels carrying crude oil from a well situated on the Continental Shelf. If the party fails to report a spill or to cooperate fully in the cleanup, the liability limits likewise do not apply and certain defenses may not be available. Moreover, OPA 90 imposes on responsible parties the need for proof of financial responsibility to cover at least some costs in a potential spill. As required, we have provided satisfactory evidence of financial responsibility to the U.S. Coast Guard for all of our vessels over 300 tons. OPA 90 also imposes ongoing requirements on a responsible party, including preparedness and prevention of oil spills and preparation of an oil spill response plan. We have engaged the National Response Corporation to serve as our independent contractor for 14 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. OPA 90 requires that all newly-built tank vessels used in the transportation of petroleum products be built with double hulls and provides for a phase-out period for existing single hull vessels. Modifying or replacing existing vessels to provide for double hulls will be required of all single-hulled tank barges and tankers in the industry by the year 2015. 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 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 OSVs routinely transport diesel fuel to offshore rigs and platforms and also carry diesel fuel for their own use. Our OSVs also transport bulk chemical materials used in drilling activities and liquid mud, which contain oil and oil by-products. In addition, our tank barges are specifically engaged to transport a variety of petroleum products. We maintain vessel response plans as required by the Clean Water Act to address potential oil and fuel 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 response costs, as well as natural resource damages. Under CERCLA, responsible parties include owners and operators of vessels. 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. The United States Coast Guard has announced proposed regulations that when adopted, would require all of our existing vessels to meet certain standards pertaining to ballast water discharge, on or before certain dates between January 2014 and July 2016. The cost of compliance with these standards is presently unknown; however, some estimates range between $250,000 and $700,000, per vessel, for Phase I compliance and additional amounts thereafter for Phase II compliance. The United States Environmental Protection Agency (“EPA”) also has recently imposed emissions regulations affecting vessels that operate in the United States. These regulations impose standards that may require modifications to our vessels at a cost that we have as yet been unable to estimate. Moreover, the EPA’s decision to regulate “green house gasses” as a pollutant may result in further regulations and compliance costs. 15 Climate Change Greenhouse gas emissions have increasingly become the subject of international, national, regional, state and local attention. Cap and trade initiatives to limit greenhouse gas emissions have been introduced in the European Union. Similarly, numerous bills related to climate change have been introduced in the U.S. Congress, which could adversely impact most industries. In addition, future regulation of greenhouse gas could occur pursuant to future treaty obligations, statutory or regulatory changes or new climate change legislation in the jurisdictions in which we operate. It is uncertain whether any of these initiatives will be implemented. However, based on published media reports, we believe that it is not reasonably likely that the current proposed initiatives in the U.S. will be implemented without substantial modification. If such initiatives are implemented, we do not believe that such initiatives would have a direct, material adverse effect on our operating results. Restrictions on greenhouse gas emissions or other related legislative or regulatory enactments could have an effect in those industries that use significant amounts of petroleum products, which could potentially result in a reduction in demand for petroleum products and, consequently and indirectly, our offshore transportation and support services. We are currently unable to predict the manner or extent of any such effect. Furthermore, one of the asserted long-term physical effects of climate change may be an increase in the severity and frequency of adverse weather conditions, such as hurricanes, which may increase our insurance costs or risk retention, limit insurance availability or reduce the areas in which, or the number of days during which, our customers would contract for our vessels in general and in the Gulf of Mexico in particular. We are currently unable to predict the manner or extent of any such effect. EMPLOYEES On December 31, 2010, we had 999 employees, including 818 operating personnel and 181 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. We have not experienced any strikes or work stoppages, and our management believes that we continue to experience good relations with our employees. SEASONALITY Demand for our offshore support 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 upstream services has historically been stronger in the second and third 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. Currently, we expect the de facto regulatory moratorium to distort the historic patterns of seasonality experienced by our Upstream business. In addition, we typically have an increase in demand for our Upstream vessels to survey and repair offshore infrastructure immediately following major hurricanes in the GoM. Downstream services are significantly affected by the strength of the U.S. economy, changes in weather patterns and population growth that affect the consumption of and the demand for refined petroleum products and crude oil. The Downstream market has been 16 historically impacted by seasonal weather patterns. Demand for heating oil in the northeastern United States, which is a significant market for our Downstream services, is generally driven by temperature levels experienced during the winter months. Normal winter conditions in the northeastern United States usually drive demand higher from December through March. However, unseasonably mild winters result in significantly lower demand during such months. In addition, the summer driving season, notwithstanding the impact of general economic trends such as gasoline price volatility, can increase demand for automobile fuel and, accordingly, the demand for our marine transportation services.

ITEM 1A—Risk Factors Our results of operations and financial condition can be adversely affected by numerous risks. You should carefully consider the risks described below as well as the other information we have provided in this Annual Report on Form 10-K. The risks described below are not the only ones we face. You should also consider the factors contained in our “Forward Looking Statements” disclaimer found on page 1 of this Annual Report on Form 10-K. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. 17 Demand for our OSV 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: (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) local and international political and economic conditions and policies, including the de facto regulatory moratorium on drilling permits in the GoM; changes in capital spending budgets by our customers; unavailability of drilling rigs in the GoM, our principal operating area; prevailing oil and natural gas prices and expectations about future prices and price volatility; the cost of offshore exploration for, and production and transportation of, oil and natural gas; successful exploration for, and production and transportation of, oil and natural gas from onshore sources; (cid:129) worldwide demand for oil and natural gas; (cid:129) (cid:129) (cid:129) consolidation of oil and gas and oil service companies operating offshore; availability and rate of discovery of new oil and natural gas reserves in offshore areas; technological advances affecting energy production and consumption; (cid:129) weather conditions; (cid:129) (cid:129) environmental and other regulation affecting our customers and their other service providers; and the ability of oil and gas companies to generate or otherwise obtain funds for exploration and production. We expect levels of oil and gas exploration, development and production activity to continue to be volatile and affect the demand for our Upstream and Downstream services. Oil and natural gas prices are volatile. A downturn in oil prices or further deterioration in natural gas prices is likely to cause a decline in expenditures for exploration, development and production activity, which would likely result in a corresponding decline in the demand for OSVs and MPSVs and thus decrease the utilization and dayrates of our OSVs and MPSVs. Such decreases could negatively impact our financial condition and results of operations. 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 necessarily result in increased demand for our OSVs and MPSVs and could adversely affect utilization of our tugs and tank barges. 18 Increases in the supply of vessels could decrease dayrates. In addition to our own vessel building programs, which were completed in 2010, certain of our competitors have announced plans to construct new vessels to be deployed in domestic and foreign locations. A remobilization to the GoM oilfield of U.S.-flagged vessels currently operating in other regions or in non-oilfield applications would result in an increase in vessel capacity in our primary market. Similarly, vessel capacity in foreign markets may also be impacted by U.S.-flagged vessels migrating to foreign locations due to the on-going de facto regulatory moratorium in the GoM. Construction of double-hulled, ocean-going tank barges has increased ocean-going tank barge capacity. Further, a repeal, suspension or significant modification of the Jones Act, or the administrative erosion of its benefits, permitting vessels that are either foreign-flagged, foreign-built, foreign-owned, foreign- controlled or foreign-operated to engage in the U.S. coastwise trade, would also result in an increase in capacity. Any increase in the supply of OSVs or MPSVs, whether through new construction, refurbishment or conversion of vessels from other uses, remobilization or changes in law or its application, could not only increase competition for charters and lower utilization and dayrates, which would adversely affect our revenues and profitability, but could also worsen the impact of any downturn in the oil and gas industry on our results of operations and financial condition. Similarly, any increase in the supply of ocean-going tank barges, could not only increase competition, domestically and internationally, for charters and lower utilization and dayrates, which could negatively affect our revenues and profitability, but could also worsen the impact of any reduction in domestic consumption of refined petroleum products or crude oil on our results of operations and financial condition. Because some services provided by MPSVs are not protected by the Jones Act, foreign competitors may bring MPSVs to the GoM or build additional MPSVs that we will compete with domestically or internationally. Intense competition in our industry could reduce our profitability and market share. Contracts for our vessels are generally awarded on an intensely competitive basis. Some of our competitors, including diversified multinational companies in the Upstream segment, 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 and utilization rates. 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. Some of our competitors may also be willing to accept lower dayrates in order to maintain utilization, which can have a negative impact on dayrates and utilization in both of our market segments. Similarly, competition in foreign markets may also be impacted by U.S.-flagged vessels migrating to foreign locations due to the on-going de facto regulatory moratorium in the GoM. Moreover, customer demand for vessels under our recently completed construction or conversion programs may not be as strong as we have anticipated and our inability to obtain contracts on anticipated terms or at all may have a material adverse effect on our revenues and profitability. 19 The failure to successfully complete construction or conversion of our vessels or repairs, maintenance and routine drydockings on schedule and on budget and to utilize such vessels and the other vessels in our fleet at profitable levels could adversely affect our financial condition and results of operations. We currently do not have any new generation OSVs or MPSVs under construction or conversion although we may plan to construct or convert additional such vessels as market conditions warrant. We also routinely engage shipyards to drydock our vessels for regulatory compliance and to provide repair and maintenance. Our construction projects and drydockings are subject to the risks of delay and cost overruns inherent in any large construction project, including shortages of equipment, lack of shipyard availability, 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 or anticipated revenues with respect to vessels under construction, conversion or for other drydockings. Further, significant cost overruns or delays for vessels under construction, conversion or retrofit not adequately protected by liquidated damages provisions, in general could adversely affect our financial condition and results of operations. In addition, our Upstream vessels are sometimes chartered or hired to provide services to a specified drilling rig or project. A delay in the availability of the drilling rig or other project delays may have an adverse impact on our utilization of the contracted vessel and thus on our financial condition and results of operations. We have grown, and may continue to grow, through acquisitions that give rise to risks and challenges that could adversely affect our future financial results. We regularly consider possible acquisitions of single vessels, vessel fleets and businesses that complement our existing operations to enable us to grow our business. Acquisitions can involve a number of special risks and challenges, including: (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) diversion of management time and attention from our existing business and other business opportunities; delays in closing or the inability to close an acquisition for any reason, including third party consents or approvals; any unanticipated negative impact on us of disclosed or undisclosed matters relating to any vessels or operations acquired; loss or termination of employees, including costs associated with the termination or replacement of those employees; assumption of debt or other liabilities of the acquired business, including litigation related to the acquired business; the incurrence of additional acquisition-related debt as well as increased expenses and working capital requirements; dilution of stock ownership of existing stockholders; increased costs and efforts in connection with compliance with Section 404 of the Sarbanes-Oxley Act; and substantial accounting charges for restructuring and related expenses, impairment of goodwill, amortization of intangible assets, and stock-based compensation expense. 20 Even if we consummate an acquisition, the process of integrating acquired operations into our own may result in unforeseen operating difficulties and costs and may require significant management attention and financial resources. In addition, integrating acquired businesses may impact the effectiveness of our internal control over financial reporting. Any of the foregoing, and other factors, could harm our ability to achieve anticipated levels of utilization and profitability from acquired vessels or businesses or to realize other anticipated benefits of acquisitions. 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 or closing such acquisitions on satisfactory terms. An inability to acquire additional vessels or businesses may limit our growth potential. Revenues from our Downstream business could be further 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 Downstream services and other conditions. A reduction in domestic consumption of refined petroleum products or crude oil has adversely affected the revenues of our Downstream business and could worsen. Further worsening could affect our financial condition and results of operation. Weather conditions also affect demand for our Downstream 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 Downstream services, the cost of compliance with homeland security, environmental regulations or increased liabilities connected with the transportation of refined petroleum products and crude oil. For example, 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 petroleum products, such activity could have an adverse effect on our ability to compete in particular markets. The early termination of contracts on our vessels could have an adverse effect on our operations. Some of the long-term contracts for our vessels and all contracts with governmental entities and national oil companies contain early termination options in favor of the customer; however, some have early termination remedies or other provisions 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 remedies or the threat of litigation with us. Until replacement of such business with other customers, any termination could temporarily disrupt our business or otherwise adversely affect our financial condition and results of operations. We might not be able to replace such business on economically equivalent terms. 21 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, local and foreign 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, the Environmental Protection Agency and the United States Customs Service, and their foreign equivalents, 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 United States Coast Guard and 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, regulations and standards may require installation of costly equipment, increased manning, or operational changes. While we endeavor to comply with all applicable laws, we might not and our 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 in ways that substantially increase costs that we may not be able to pass along to our customers. Any changes in laws, regulations or standards that would impose additional requirements or restrictions could adversely affect our 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), including vessels under construction in the United States. If one of our OSVs, MPSVs, 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, MPSVs, tugs or tank barges. The purchase or the requisition for an extended period of time of one or more of our vessels could adversely affect our results of operations and financial condition. Finally, we are subject to the Merchant Marine Act of 1920, commonly referred to as the Jones Act, which requires that vessels engaged in coastwise trade to carry cargo between U.S. ports be documented under the laws of the United States and be controlled by U.S. citizens. We endeavor to ensure that we would be determined to be a U.S. citizen as defined under these laws by including in our certificate of incorporation certain restrictions on the ownership of our capital stock by non-U.S. citizens and establishing certain mechanisms to 22 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. The Jones Act’s provisions restricting coastwise trade to vessels controlled by U.S. citizens have recently been circumvented by foreign interests that seek to engage in trade reserved for vessels controlled by U.S. citizens and otherwise qualifying for coastwise trade. Legal challenges against such actions are difficult, costly to pursue and are of uncertain outcome. To the extent such efforts are successful and foreign competition is permitted, such competition could have a material adverse effect on domestic companies in the offshore service vessel industry and on our financial condition and results of operations. In addition, in the interest of national defense, the Secretary of Homeland Security is authorized to suspend the coastwise trading restrictions imposed by the Jones Act on vessels not controlled by U.S. citizens. Such a waiver was issued following Hurricane Katrina and was in effect on a temporary basis for tank vessels that carried petroleum products. A more limited waiver continues in existence for vessels that carry petroleum cargoes from the Strategic Petroleum Reserve. 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. Our vessels are subject to operating risks such as: (cid:129) (cid:129) catastrophic marine disaster; adverse weather and sea conditions; (cid:129) mechanical failure; (cid:129) (cid:129) (cid:129) (cid:129) collisions or allisions; oil and hazardous substance spills; navigation errors; acts of God; and (cid:129) 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 and possible penalties, that pursuant to typical marine indemnity policies, we must pay and then seek reimbursement from our insurer. 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 and we do not maintain insurance for loss of income resulting from a marine casualty. 23 Our expansion of operations into international markets and shipyard activities in foreign shipyards subjects us to risks inherent in conducting business internationally. Over the past several years we have derived an increasing portion of our revenues from foreign sources. In addition, certain of our shipyard repair and procurement activities are being conducted with foreign vendors. We therefore face risks inherent in conducting business internationally, such as legal and governmental regulatory requirements, potential vessel seizure or nationalization of assets, import-export quotas or other trade barriers, difficulties in collecting accounts receivable and longer collection periods, political and economic instability, kidnapping of or assault on personnel, piracy, adverse tax consequences, difficulties and costs of staffing international operations and language and cultural differences. We do not hedge against foreign currency risk. While we endeavor to contract in U.S. Dollars when operating internationally, some contracts may be denominated in a foreign currency, which would result in a foreign currency exposure risk. All of these risks are beyond our control and difficult to insure against. We cannot predict the nature and the likelihood of any such events. If such an event should occur, however, it could have a material adverse effect on our financial condition and results of operations. We may lose the right to operate in some international markets in which we have a presence. In certain foreign markets in which we operate, most notably Mexico and Brazil, we depend upon governmental waivers of cabotage laws. These waivers could be revoked or made more burdensome, which could result in our inability to continue our operations or materially increase the costs of operating in such foreign locations. Future results of operations depend on the long-term financial stability of our customers. Some of the contracts we enter into for our vessels are full utilization contracts with initial terms ranging from one to five years. We enter into these 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 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 could impair our ability to manage, maintain and grow our business. In crewing our vessels, 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 vessel employees may choose to pursue employment in fields that offer a more desirable work environment at wage rates that are competitive with ours. 24 With a reduced pool of workers, it is possible that we will have to raise wage rates to attract workers 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 financial condition and results of operations may be adversely affected. If we are unable to recruit qualified personnel we may not be able to operate our vessels at full utilization, which would adversely affect our results of operations. 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 preempt state workers’ compensation laws and permit these employees and their representatives to pursue actions against employers for job-related incidents in federal courts based on tort theories. Because we are not generally protected by the damage limits imposed by state workers’ compensation statutes for these types of claims, 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 financial condition and results of operations. Restrictions contained in the indentures governing our 6.125% senior notes due 2014 and our 8.000% senior notes due 2017 and in the agreement governing our revolving credit facility may limit our ability to obtain additional financing and to pursue other business opportunities. Covenants contained in the indentures governing our 6.125% senior notes due 2014 and our 8.000% senior notes due 2017 and in the agreement governing our revolving credit facility require us to meet certain financial tests, which may limit or otherwise restrict: (cid:129) (cid:129) (cid:129) our flexibility in operating, 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; and our ability to obtain additional financing for working capital, capital expenditures, including our newbuild programs, acquisitions, general corporate and other purposes. We have high levels of fixed costs that will be incurred regardless of our level of business activity. Our business has high fixed costs. Downtime or low productivity due to reduced demand, as experienced in 2009 and 2010, weather interruptions or other causes can have a significant negative effect on our operating results and financial condition. 25 Our revenues and operating results may vary significantly from quarter to quarter due to a number of factors such as volatility in our vessel dayrates, changes in utilization, vessel incidents and other unforeseen matters. Many of these factors that may cause our actual financial results to vary from our publicly disclosed earnings guidance and forecasts are outside of our control. Our actual financial results might vary from those anticipated by us or by securities analysts and investors, and these variations could be material. From time to time we publicly provide various forms of guidance, which reflect our projections about future market expectations and operating performance. The numerous assumptions underlying such guidance may be impacted by factors that are beyond our control and might not turn out to be correct. Although we believe that the assumptions underlying our projections are reasonable, when such projections are made, actual results could be materially different, particularly with respect to our MPSVs. We are susceptible to unexpected increases in operating expenses such as materials and supplies, crew wages, maintenance and repairs, and insurance costs. Many of our operating costs are unpredictable and vary based on events beyond our control. Our gross margins will vary based on fluctuations in our operating costs. If our costs increase or we encounter unforeseen costs, we may not be able to recover such costs from our customers, which could adversely affect our financial position, results of operations and cash flows. We may not have the ability to raise the funds necessary to settle conversion of our 1.625% convertible senior notes or to purchase such notes upon a fundamental change or on other purchase dates as defined in the agreement, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of shares. Upon conversion of our 1.625% convertible senior notes, we may pay a settlement amount in cash and shares of our common stock, if any, based upon a 25 trading-day observation period. In addition, on November 15, 2013, November 15, 2016 and November 15, 2021, holders of the 1.625% convertible senior notes may require us to purchase their notes for cash. We cannot assure you that we will have sufficient financial resources, or would be able to arrange financing, to pay the settlement amount in cash, or the purchase price or fundamental change purchase price for the 1.625% convertible senior notes tendered by the holders in cash. Further, our ability to pay the settlement amount in cash, or the purchase price or fundamental change purchase price for the 1.625% convertible senior notes in cash may be subject to limitations in our revolving credit facility or any other indebtedness we may have in the future. If the holders of the 1.625% convertible senior notes convert such notes or require us to repurchase them, we may seek the consent of our lenders or attempt to refinance the debt, but there can be no assurance that we will be able to obtain consent or complete a refinancing. Failure by us to pay the settlement amount upon conversion or purchase the notes when required will result in an event of default with respect to the notes, which may also result in the acceleration of our other indebtedness, which we may not be able to satisfy. 26 The convertible note hedge and warrant transactions may affect the value of our common stock. In connection with the original issuance of our 1.625% convertible senior notes, we entered into convertible note hedge and warrant transactions with counterparties that include affiliates of the initial purchasers of the convertible senior notes. The convertible note hedge transactions are expected to reduce the potential dilution upon conversion of such notes. However, if the warrants are exercised, such exercise would mitigate some of that reduction. In connection with these hedging and warrant transactions, such counterparties or their affiliates may enter into, or may unwind, various derivatives and/or purchase or sell our common stock in secondary market transactions (and are likely to do so during any observation period related to a conversion of notes). The effect, if any, of these convertible note hedge and warrant transactions or any of these hedging activities on the market price of our common stock or the convertible senior notes will depend in part on market conditions and cannot be ascertained at this time, but any of these activities could materially and adversely affect the value of our common stock. The fundamental change purchase feature of our 1.625% convertible senior notes and provisions of our certificate of incorporation, bylaws, stockholder rights plan and Delaware law may delay or prevent an otherwise beneficial takeover attempt of our company. The terms of our 1.625% convertible senior notes require us to purchase the notes for cash in the event of a fundamental change. A takeover of our company would trigger the requirement that we purchase the notes. Furthermore, our certificate of incorporation and bylaws, Delaware corporations law, and our stockholder rights plan contain provisions 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 and may have the effect of delaying or preventing a takeover of our company that would otherwise be beneficial to investors. Conversion of the 1.625% convertible senior notes or exercise of the warrants issued in the warrant transactions may dilute the ownership interest of existing stockholders. The conversion of the 1.625% convertible senior notes or exercise of some or all of the warrants we issued in the warrant transactions may dilute the ownership interests of existing stockholders. Although the convertible note hedge transactions are expected to reduce potential dilution upon conversion of the 1.625% convertible senior notes, the warrant transactions could have a dilutive effect on our earnings per share to the extent that the price of our common stock exceeds the strike price of the warrants. Any sales in the public market of our common stock issuable upon such conversion of the 1.625% convertible senior notes could adversely affect prevailing market prices of our common stock. In addition, the anticipated exercise of the warrants for shares of our common stock could depress the price of our common stock. 27 We may not have the funds available or be able to obtain the funds necessary to repay our 6.125% senior notes due 2014, or 2014 senior notes, and our 8.000% senior notes due 2017, or 2017 senior notes, upon maturity or to repurchase such notes at the option of the holder upon the occurrence of certain change of control events prior to their maturity. Our 2014 senior notes and 2017 senior notes mature in November 2014 and August 2017, respectively. In addition, upon the occurrence of certain change of control events, as defined in the indentures governing such notes, holders of our 2014 senior notes and 2017 senior notes would have the right to require us to repurchase such notes at 101% of their principal amount, plus accrued and unpaid interest, if any. We cannot be certain that we will have sufficient funds available or that we will have the ability to obtain additional financing, to obtain a waiver, consent or an extension from our lenders, or to raise funds by disposing of one or more of our assets to repay such notes upon maturity or upon any change of control event that would require us to repurchase the 2014 senior notes or 2017 senior notes that may be tendered by our bondholders, if any. Failure by us to repay such notes upon maturity or to repurchase such notes when required would result in an event of default with respect to such notes, which may also result in the acceleration of our other outstanding indebtedness, which we may not have sufficient funds to repay. We may be adversely affected by uncertainty in the global financial markets. Our future results may be impacted by continued volatility, weakness or deterioration in the debt and equity capital markets. Inflation, deflation, or other adverse economic conditions may negatively affect us or parties with whom we do business resulting in their non-payment or inability to perform obligations owed to us, such as the failure of customers to honor their commitments, the failure of shipyards and major suppliers to complete orders or the failure by banks to provide expected funding under our revolving credit agreement. Additionally, credit market conditions may slow our collection efforts as customers experience increased difficulty in obtaining requisite financing, potentially leading to lost revenue and higher than normal accounts receivable. This could result in greater expense associated with collection efforts and increased bad debt expense. The cost of raising money in the debt and equity capital markets has increased substantially during the ongoing financial crisis while the availability of funds from those markets has diminished significantly. The current global economic downturn may adversely impact our ability to issue additional debt and equity in the future on acceptable terms. Also, the cost of obtaining money from the credit markets has increased as many lenders and institutional investors have increased interest rates, enacted tighter lending standards, refused to refinance existing debt upon maturity or on terms similar to expiring debt. If we require additional sources of short-term liquidity for any reason including without limitation the factors stated above, our existing lenders may be unable or unwilling to extend credit to us. Due to these factors, we cannot be certain that additional funding will be available if needed and to the extent required, on acceptable terms. We may be unable to collect amounts owed to us by our customers. We typically grant our customers credit on a short-term basis. Related credit risks are inherent as we do not typically collateralize receivables due from customers. We provide 28 estimates for uncollectible accounts based primarily on our judgment using historical losses, current economic conditions and individual evaluations of each customer as evidence supporting the receivables valuations stated on our financial statements. However, our receivables valuation estimates may not be accurate and receivables due from customers reflected in our financial statements may not be collectible. Changes in legislation, policy, restrictions or regulations for drilling in the Gulf of Mexico that cause delays or deter new drilling could have a material adverse effect on our financial position, results of operations and cash flows. In response to the April 20, 2010, Deepwater Horizon incident, the U.S. government and its regulatory agencies with jurisdiction over oil and gas exploration, including the DOI and the Bureau of Ocean Energy Management, Regulation and Enforcement, or BOEMRE, have responded to the Deepwater Horizon incident by imposing moratoria on drilling operations, by requiring operators to reapply for exploration plans and drilling permits which had previously been approved and by adopting numerous new regulations and new interpretations of existing regulations regarding operations in the U.S. Gulf of Mexico that are applicable to our Upstream customers and with which their new applications for exploration plans and drilling permits must prove compliant. Compliance with these new regulations and new interpretations of existing regulations may materially increase the cost of drilling operations in the U.S. GoM, which could materially adversely impact our business, financial position or results of operations. The uncertainty surrounding the timing and cost of drilling activities in the U.S. GoM is primarily the result of (i) newly issued regulations by the DOI and BOEMRE, (ii) on-going clarifications and interpretive guidance often in the form of an NTL issued by the DOI and the BOEMRE relating to these newly issued regulations as well as with respect to existing regulations, (iii) continuing compliance efforts relating to these regulations, clarifications and guidance, (iv) uncertainty as to the ability of the BOEMRE to timely review submissions and issue drilling permits, (v) the general uncertainty regarding additional regulation of the oil and gas industry’s operations in the U.S. GoM and (vi) on-going and potential third party legal challenges to industry drilling operations in the U.S. GoM. We do not expect that drilling activities in the GoM will recommence until such time that legal issues surrounding the new statutory and regulatory restrictions and the de facto regulatory moratorium is resolved to the satisfaction of operators and regulators. In addition, the commission appointed by the President of the United States to study the causes of the catastrophe released its report and has recommended certain legislative and regulatory measures that should be taken to minimize the possibility of a reoccurrence of a disastrous spill. Various bills are being considered by Congress which, if enacted, could either significantly impact drilling and exploration activities in the GoM, particularly in the deepwater areas, or possibly drive a substantial portion of drilling and operational activity out of the GoM. Given the current restrictions, potential future restrictions and the uncertainty surrounding the availability of any exceptions to any restrictions, we cannot predict when our GoM oil and gas exploration and production customers will be able to continue their drilling activities to any significant degree in the U.S. GoM. A prolonged suspension of or delay in these drilling operations would have a material adverse effect on our business, financial position or future results of operations. Moreover, the uncertainty caused by such legislation, policy, restrictions or regulations for new drilling in the GoM could aggravate the potentially adverse effects of many of the risks previously identified in this Item 1A. 29 ITEM 1B—Unresolved Staff Comments None. ITEM 2—Properties Our principal executive offices are in Covington, Louisiana, where we lease approximately 61,000 square feet of office space under leases expiring in September 2013. Our primary domestic operating offices are located in Port Fourchon, Louisiana, and Brooklyn, New York. For more information, see Management’s Discussion and Analysis of Financial Condition and Results of Operations included within this report. 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.

We presently intend to retain all of the cash our business generates to meet our working capital requirements and fund future growth. Any future payment of cash dividends will depend upon the financial condition, capital requirements, plans to reduce our long-term debt and earnings of our Company, as well as other factors that our Board of Directors may deem relevant. In addition, the indentures governing our 6.125% senior notes and our 8.000% senior notes and the agreement governing our revolving credit facility include restrictions on our ability to pay cash dividends on our common stock.

This impairment charge is reflected in depreciation expense for the year ended December 31, 2009. The Company’s amortization expense for such period includes a $0.9 million pre-tax non-cash charge for the write-off of remaining goodwill associated with our Downstream segment. Effective January 1, 2007, we modified our assumptions regarding estimated salvage values for its marine equipment. Salvage values for marine equipment are estimated to range between 5% and 25% of the originally recorded cost, depending on vessel type. For the year ended December 31, 2007, this change in estimated salvage values resulted in an increase in operating income, net income and diluted earnings per share of approximately $6.2 million, $4.0 million and $0.15, respectively. (2) Represents other operating income and expenses, including equity in income from investments and foreign currency transaction gains or losses. (3) For the years ended December 31, 2010, 2009, 2008, 2007, and 2006 stock options representing rights to acquire 400, 414, 3, 146, and 323 shares, respectively, of common stock were excluded from the calculation of diluted earnings per share because the effect was anti-dilutive after considering the exercise price of the options in comparison to the average market price, proceeds from exercise, taxes and related unamortized compensation. See Note 3 of our consolidated financial statements for more information on diluted shares outstanding. (4) Excludes original issue discount associated with our 6.125% senior notes in the amount of $279, $341, $398, $453, and $503 as of December 31, 2010, 2009, 2008, 2007, and 2006, respectively, original issue discount associated with our 8.000% senior notes in the amount of $6,305, and $6,980 as of December 31, 2010 and 2009 and original issue discount associated with our 1.625% convertible senior notes in the amount of $35,183, $46,005, $56,083, $65,471, and $74,215 as of December 31, 2010, 2009, 2008, 2007, and 2006, respectively. (5) See our discussion of EBITDA as a non-GAAP financial measure immediately following these footnotes. (6) We owned 51 new generation OSVs as of December 31, 2010. Our average number of new generation OSVs for the years ended December 31, 2010, 2009 and 2008 reflect the deliveries of several vessels under our fourth OSV newbuild program. During 2010, 2009 and 2008, we placed in service, four OSVs, eight OSVs and four OSVs, respectively. Please refer to the New Generation OSVs table on page 6 of the Form 10-K for more information about vessel names and placed in service dates. Our average number of new generation OSVs for the year ended December 31, 2007 includes ten new generation OSVs that were acquired in August 2007. Excluded from this data are ten conventional OSVs that were also acquired in August 2007, nine of which have been sold on various dates in 2008, 2009, and 2010. Our remaining conventional OSV, which is stacked, is considered a non-core asset. In response to weak market conditions we elected to stack certain of our new generation OSVs on various dates in 2009 and 2010. Active new generation OSVs represent vessels that are immediately available for service during each respective period. (7) (8) Utilization rates are average rates based on a 365-day year. Vessels are considered utilized when they are generating revenues. (9) Effective utilization rate is based on a denominator comprised only of vessel-days available for service by the active fleet, which excludes the impact of stacked vessel days. (10) Average dayrates represent average revenue per day, which includes charter hire, crewing services and net brokerage revenues, based on the number of days during the period that the OSVs generated revenue. (11) Effective dayrate represents the average dayrate multiplied by the average utilization rate. (12) Other operating data for tugs and tank barges reflects only the results from our double-hulled tank barges as our single-hulled tank barges are considered non-core assets. Our active Downstream fleet is comprised of nine double-hulled barges and nine ocean-going tugs. (13) The averages for the years ended December 31, 2010, December 31, 2009, December 31, 2008 and December 31, 2007 include the Energy 6506, Energy 6507 and Energy 6508, three double-hulled tank barges delivered under our second TTB newbuild program in August 2007, November 2007, and March 2008, respectively. As of December 31, 2010, our double-hulled tank barge fleet consisted of nine vessels. (14) 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 is equal to the cost of in-chartering third-party equipment paid by customers. 33 Non-GAAP Financial Measures We disclose and discuss EBITDA as a non-GAAP financial measure in our public releases, including quarterly earnings releases, investor conference calls and other filings with the Commission. We define EBITDA as earnings (net income) before interest, income taxes, depreciation and amortization. Our measure of EBITDA may not be comparable to similarly titled measures presented by other companies. Other companies may calculate EBITDA differently than we do, which may limit their usefulness as comparative measures. We view EBITDA primarily as a liquidity measure and, as such, we believe that the GAAP financial measure most directly comparable to this measure is cash flows provided by operating activities. Because EBITDA is not a measure of financial performance calculated in accordance with GAAP, it should not be considered in isolation or as a substitute for operating income, net income or loss, cash flows provided by operating, investing and financing activities, or other income or cash flow statement data prepared in accordance with GAAP. EBITDA is widely used by investors and other users of our financial statements as a supplemental financial measure that, when viewed with our GAAP results and the accompanying reconciliation, we believe provides additional information that is useful to gain an understanding of the factors and trends affecting our ability to service debt, pay deferred taxes and fund drydocking charges and other maintenance capital expenditures. We also believe the disclosure of EBITDA helps investors meaningfully evaluate and compare our cash flow generating capacity from quarter to quarter and year to year. EBITDA is also a financial metric used by management (i) as a supplemental internal measure for planning and forecasting overall expectations and for evaluating actual results against such expectations; (ii) as a significant criteria for annual incentive cash bonuses paid to our executive officers and other shore-based employees; (iii) to compare to the EBITDA of other companies when evaluating potential acquisitions; and (iv) to assess our ability to service existing fixed charges and incur additional indebtedness. The following table provides the detailed components of EBITDA as we define that term for the years ended December 31, 2010, 2009, 2008, 2007 and 2006 respectively (in thousands).

We believe that these ratios are a material component of certain financial covenants in such credit agreements and failure to comply with the financial covenants could result in the acceleration of indebtedness or the imposition of restrictions on our financial flexibility. The applicable covenants contained in our credit facility are described in the Liquidity and Capital Resources section of Item 7. The following table provides certain detailed adjustments to EBITDA, as defined in our revolving credit facility for the years ended December 31, 2010, 2009, 2008, 2007, and 2006 respectively (in thousands).

(cid:129) EBITDA does not reflect the future capital expenditure requirements that may be necessary to replace our existing vessels as a result of normal wear and tear, (cid:129) EBITDA does not reflect the interest, future principal payments and other financing- related charges necessary to service the debt that we have incurred in acquiring and constructing our vessels, (cid:129) EBITDA does not reflect the deferred income taxes that we will eventually have to pay once we are no longer in an overall tax net operating loss carryforward position, as applicable, and (cid:129) EBITDA does not reflect changes in our net working capital position. Management compensates for the above-described limitations in using EBITDA as a non-GAAP financial measure by only using EBITDA to supplement our GAAP results. 35 Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations The following management’s discussion and analysis of financial condition and results of operations should be read in conjunction with our historical consolidated financial statements and their notes included elsewhere in this Annual Report on Form 10-K. 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 or as a result of certain factors such as those set forth in our Forward Looking Statements disclaimer on page 1 of this Annual Report on Form 10-K. Outlook In response to the April 20, 2010, Deepwater Horizon incident, the United States Department of the Interior, or the DOI, ordered a moratorium on all deepwater drilling on the Outer Continental Shelf, or OCS, effective May 30, 2010. This moratorium was lifted by the DOI on October 12, 2010. In addition, through the issuance of Notices to Lessees, or NTLs, as well as through the promulgation of new rules, the DOI has imposed significant new regulations governing all drilling in the U.S. Gulf of Mexico, or GoM, including shallow-water drilling. The DOI has indicated that it intends to issue additional new regulations, which are expected to impose further requirements affecting all drilling operations. The immediate effect of the DOI’s regulatory actions has been to drastically curtail the level of drilling activity in the GoM, which is our primary market and the primary demand driver for our type of vessels in that market. While we expect that drilling activity will resume as operators begin to comply with the new regulations, we cannot predict if or when activity in the GoM will return to levels that existed prior to the Deepwater Horizon event for at least the first half of 2011. The timing of a market recovery will depend upon several factors outside of our control including 1) the ability of operators and drilling contractors to comply with the new rules; 2) the content of additional as yet unpromulgated rules that are expected to be issued; 3) the content of oil spill legislation that may be enacted by the U.S. Congress; and 4) general economic conditions. These actions will adversely affect our operating results in the first half of 2011 and possibly beyond. In response to these events, we have taken measures to 1) reduce our operating costs by stacking vessels, including vessels that were recently delivered under our fourth OSV newbuild program, and furloughing employees, and 2) expand our international presence by mobilizing vessels out of the GoM into foreign markets. The deployment of additional vessels to foreign markets will take time, resulting in periods in which they are not earning revenue and will require us to make expenditures necessary for such repositioning. In addition, the ability to obtain charters in international locations is not certain given the competition that exists for such charters, which may increase as more vessels depart the GoM in response to current regulatory constraints and market conditions. We believe several international markets are currently oversupplied and dayrates in those markets are low in comparison to historic norms. In order to enhance our competitiveness in Mexico, we previously re-flagged, or placed under Mexican registry, two of our older new generation U.S.-flagged vessels and expect to place an additional three such vessels under Mexican registry in March 2011. Because we anticipate long-term growth in our 36 Mexican and Brazilian operations, we may re-flag additional U.S.-flagged vessels in those markets. Once a U.S.-flagged vessel changes its registry and is re-flagged, it loses its eligibility to return to U.S. coastwise trade. In addition to international deployments, we will also continue to seek additional production-related, decommissioning, specialty-work or other non-oilfield markets for our vessels both in the United States and abroad. Generally, operations of this kind are not affected by the on-going de facto regulatory moratorium in the GoM. The de facto regulatory moratorium is, however, adversely impacting our ability to predict utilization of our MPSVs. While several operators have indicated a strong interest in utilizing our 370 class MPSVs, we believe more regular and predictable utilization will be contingent upon the issuance of permits in the deepwater GoM by BOEMRE. Utilization of our 430 class MPSV’s is less impacted by drilling permits. However, because these vessels are utilized for construction and other projects with long-lead times, some of which may be impacted by the de facto regulatory moratorium, we are experiencing light utilization of these vessels in the GoM thus far in 2011. In connection with our litigation brought against the DOI, we filed a Motion for Recovery of Attorney’s Fees and Costs against the DOI. On February 2, 2011 the motion was granted on the basis that the DOI was found in contempt of the Court’s injunction order. The Court has referred our claim to a magistrate judge to decide the monetary award for such fees and costs to which we are entitled. In addition to the delayed issuance of drilling permits in the GoM, weakness in the overall economy continues to negatively impact dayrates and utilization for each of our business segments. We have not seen any improvement of the prevailing weak market conditions in our Downstream segment. With our participation in the BP oil spill response activities, we experienced a temporary increase in demand for our Upstream and Downstream equipment during 2010. However, this demand driver significantly declined once the oil well was successfully capped. For the year ended December 31, 2010, we recorded approximately $102.1 million in consolidated revenue related to oil spill response activities. Our primary customer for these activities was BP. As drilling in the GoM begins to resume, we do not expect that it will do so evenly. As a consequence, for a period, we expect that operators will first utilize vessels under long-term contracts to meet their needs and competition for charters will be intense. Because we have been forced to furlough some employees, we may also face competition to rehire mariners as demand resumes, which could negatively impact our operating costs. Upstream Segment Our average new generation OSV dayrates for the year ended December 31,2010 were approximately $21,600 and our average OSV utilization was approximately 72%. During 2010, our average OSV utilization was adversely affected by roughly 2,700 days out-of-service related to stacked vessels and approximately 962 days of aggregate downtime related to customer-required modifications and pre-positioning of eight vessels that were mobilized to Brazil during 2010 for multi-year charters. The deepwater drilling moratorium and de facto regulatory moratorium in the GoM also contributed to the lower Upstream utilization. This demand decline was temporarily offset by an expansive effort by BP to deploy marine 37 assets to control the well and recover the oil spilled. During the year ended December 31, 2010, we had as many as 12 new generation OSVs and four MPSVs assisting with oil spill- related activities, which represented approximately 11% and 63% of the total new generation OSV and MPSV vessel-days worked, respectively. As of December 31, 2010, no new generation OSVs or MPSVs remained on charter for oil spill response activities. Notwithstanding the “lifting” of the deepwater drilling moratorium, until the Bureau of Ocean Energy Management, Regulation and Enforcement, or BOEMRE, begins issuing drilling permits to our customers with some degree of regularity, the uncertainty surrounding the demand outlook for the entire Upstream segment in the GoM will continue. We believe only a few permits have been issued for drilling in the deepwater GoM and such permits related to wells that had commenced prior to the Deepwater Horizon incident. As of December 31, 2010, we had 15 new generation vessels stacked and may also elect to stack additional Upstream vessels while GoM market conditions remain weak. As of December 31, 2010, our 36 active new generation OSVs and four MPSVs were operating in domestic and international areas as noted in the following table: Operating Areas Domestic GoM . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

(3) Excluded from this table are 15 of our new generation OSVs and one conventional OSV that were stacked as of December 31, 2010. OSV Newbuild Program. Our fourth OSV newbuild program consisted of vessel construction contracts with three domestic shipyards to build six 240 ED class OSVs, nine 250 EDF class OSVs and one 290 class OSV. Of the 16 new generation DP-2 OSVs included in this program, we placed in service four vessels in 2008, eight vessels in 2009, and four vessels in 2010. With the last four remaining vessels placed in service in 2010, our fourth OSV newbuild program has been completed. The aggregate cost of this program, prior to the allocation of construction period interest, was approximately $431.6 million. For further information regarding our fourth OSV newbuild program, please refer to the Capital Expenditures and Related Commitments section. MPSV Program. Our MPSV program included the conversion of two coastwise sulfur tankers into U.S.-flagged, proprietary 370 class DP-2 new generation MPSVs at domestic shipyards, and the newbuild construction of two 430 class DP-3 new generation MPSVs at foreign shipyards. With the second converted 370 class MPSV, the HOS Strongline, being placed in service in March 2010, the MPSV program has been completed. The aggregate cost of the MPSV program, prior to the allocation of construction period interest, was 38 approximately $491.1 million. We also have an exclusive four-year option to construct two additional “sister vessels” based on the same 430 class DP-3 MPSV design at a U.S. shipyard of our choice, which would qualify for domestic coastwise trade under the Jones Act. For further information regarding our MPSV program, please refer to the Capital Expenditures and Related Commitments section. The HOS Centerline, the first converted 370 class MPSV, has received final certifications by the United States Coast Guard allowing operations as a supply vessel, industrial/ construction vessel and as a petroleum and chemical tanker under subchapters “L”, “I”, “D”, and “O”, respectively. During the first quarter of 2011, the HOS Strongline, the sister vessel to the HOS Centerline, received its “D” and “O” certifications and can now operate under subchapters “L”, “I”, “D”, and “O”. We believe that these vessels are not only the largest supply vessels in the world, but also the only vessels in the world to have received all four of these certifications. All of our current vessels are qualified under the Jones Act to engage in U.S. coastwise trade, except for one foreign-flagged AHTS vessel, one foreign-flagged well stimulation vessel, two foreign-flagged new generation OSVs and two foreign-flagged MPSVs. Downstream Segment As of December 31, 2010, our Downstream fleet was comprised of a mix of nine double- hulled tank barges, four single-hulled tank barges and 15 ocean-going tugs. All of our single- hulled tank barges and six lower horsepower tugs, which are non-core assets, were stacked as of December 31, 2010. We completed the sale of all four of our remaining single-hulled tank barges during the first quarter of 2011. Downstream results for the year ended December 31, 2010 were adversely impacted by the continued decline in demand for petroleum products in the U.S. In addition, approximately 2.0 million barrels of double-hulled tank barge capacity was delivered to the market since 2009, which further expands the over-supply of tank barges. These unfavorable supply/ demand fundamentals were temporarily offset by increased demand for our Downstream equipment in connection with BP’s oil spill recovery efforts. During the third quarter of 2010, we had as many as five double-hulled tank barges assisting with oil spill-related activities. As of December 31, 2010, there were no double-hulled tank barges that remained on charter related to oil spill response activities. We anticipate the weak market conditions for our Downstream vessels will continue into at least the first half of 2011 which may result in our decision to stack one or more double- hulled tank barges during the first half of 2011. With the protracted weak demand for tugs and tank barges coupled with the expansion of our Upstream fleet, we expect our Downstream segment to represent a much smaller portion of our consolidated operating results compared to historical trends. Operating Costs Our operating costs are primarily a function of fleet size, area of operations 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 are 39 incurred regardless of vessel utilization, our direct operating costs as a percentage of revenues may fluctuate considerably with changes in dayrates and utilization. By stacking under-utilized vessels, we have been able to realize some reductions in our operating costs. In certain foreign markets in which we operate, we are susceptible to higher operating costs such as materials and supplies, crew wages, maintenance and repairs, taxes, and insurance costs. Difficulties and costs of staffing international operations, including vessel crews, and language and cultural differences generally contribute to a higher cost structure in foreign locations compared to our domestic operations. We may not be able to recover higher international operating costs through higher dayrates charged to our customers. Therefore, when we increase our international complement of vessels, particularly for our Upstream segment, our gross margins may fluctuate depending on the foreign areas of operation and the complement of vessels operating domestically. In addition to the operating costs described above, we incur fixed charges related to the depreciation of our fleet and amortization of 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 capitalize costs incurred for drydock inspection and regulatory compliance and amortize such costs over the period between such drydockings, typically 30 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. While we can defer required drydockings of stacked vessels, we will be required to conduct such deferred drydockings prior to such vessels returning to service. Critical Accounting Policies Our consolidated financial statements included in this Annual Report on Form 10-K have been prepared in accordance with accounting principles generally accepted in the United States. In many cases, the accounting treatment of a particular transaction is specifically dictated by generally accepted accounting principles. In other circumstances, we are required to make estimates, judgments and assumptions that we believe are reasonable based upon available information. We base our estimates and judgments on historical experience and various other factors that we believe are reasonable based upon the information available. 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, the following may involve estimates that are inherently more subjective. Carrying Value of Vessels. We depreciate our tugs, tank barges, OSVs, and MPSVs over estimated useful lives of 14 to 25 years, three to 25 years, five to 25 years and 25 years, respectively. The shorter useful lives relate to acquired vessels. Salvage values for marine equipment range between 5% and 25% of the originally recorded cost, depending on vessel type. The useful lives used for single-hulled tank barges are based on their retirement date classification under OPA 90, and for double-hulled tank barges it is 25 years. 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 40 regulatory factors that could impact commercial viability. To date, our experience confirms that these policies are reasonable, although there may again be events or changes in circumstances in the future that indicate that recovery of the carrying amount of our vessels might not be possible. We review for impairment of our vessels by asset group. Vessels with similar operating and marketing characteristics are grouped for asset impairment review. For vessels that are not expected to be placed back into service, the impairment review is performed on a vessel-by-vessel basis. Examples of events or changes in circumstances that could indicate that the recoverability of the carrying amount of our asset groups should be assessed might include a change in regulations such as OPA 90, a significant decrease in the market value of the asset group 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 the asset group. If events or changes in circumstances as set forth above indicate that the asset group’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 asset group and its eventual disposition. If the sum of the expected future cash flows is less than the carrying amount of the vessel, we would be required to reduce the carrying amount to fair value. Fair value is determined by using appropriate valuation techniques such as expected discounted cash flows and third-party appraisals. Please refer to Note 14 of our consolidated financial statements included herein. Recertification Costs. Our vessels 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. We expense routine repairs and maintenance as they are incurred. Recertification costs can be accounted for in one of two ways: (1) defer and amortize or (2) expense as incurred. We defer and amortize recertification costs over the length of time that the recertification is expected to last, which is generally 30 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 judgments we make regarding whether the specific cost incurred is capitalizable and the period that the incurred cost will benefit. Mobilization Costs. Vessels will routinely move to and from international and domestic operating areas. Mobilization costs associated with relocating vessels typically include fuel, crew costs, vessel modifications, materials and supplies or other pre-positioning expenses required by the customer. The extent of mobilization costs incurred to relocate a vessel is directly related to the customer contract terms and area of operation. Some of our charter agreements provide for us to recover mobilization costs through either direct reimbursement or higher dayrates charged to our customers. Unless mobilization costs are rebillable to customers, we typically expense these costs as incurred. Revenue Recognition. We charter our vessels to customers under time charters based on a daily rate of hire and recognize revenue as earned on a daily basis during the contract period of the specific vessel. We also contract our Downstream vessels to customers under COAs, under which revenue is recognized based on the number of days incurred for the voyage as a percentage of total estimated days applied to total estimated revenues. Voyage related costs are expensed as incurred. Substantially all voyages under COAs are less than 10 days in length. 41 Allowance for Doubtful Accounts. Our customers are primarily major and independent, domestic and international, oil and gas and oil service companies. Our customers are granted credit on a short-term basis and related credit risks are considered minimal. We usually do not require collateral. We provide an estimate for uncollectible accounts based primarily on management’s judgment. Management uses historical losses, current economic conditions and individual evaluations of each customer to make adjustments to the allowance for doubtful accounts. Our historical losses have not been significant. However, because amounts due from individual customers can be significant, future adjustments to the allowance can be material if one or more individual customer’s balances are deemed uncollectible. Income Taxes. We follow accounting standards for income taxes as set forth by the Financial Accounting Standards Board which requires the use of the liability method of computing deferred income taxes. Under this method, deferred income taxes are provided for the temporary differences between the financial reporting basis and the tax basis of our assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The assessment of the realization of deferred tax assets, particularly those related to tax net operating loss carryforwards, involves the use of management’s judgment to determine whether it is more likely than not that we will realize such tax benefits in the future. In addition, each reporting period, we assess and adjust for any significant changes to our liability for unrecognized income tax benefits. We account for any interest and penalties relating to uncertain tax positions in general and administrative expenses. Stock-Based Compensation Expense. In accordance with accounting standards set forth by the Financial Accounting Standards Board all share-based payments to employees and directors, including grants of stock options and restricted stock are recognized in the income statement based on their fair values. Convertible Senior Notes. Effective January 1, 2009, we retroactively applied new accounting rules set forth by the Financial Accounting Standards Board regarding the Company’s 1.625% convertible senior notes due 2026, or convertible senior notes. The new requirements state that the liability and equity components of a convertible debt instrument that may be settled in cash upon conversion be accounted for separately so that an entity’s accounting reflects additional non-cash original issue discount, or OID, interest expense to match the non-convertible debt borrowing rate when interest cost is recognized in subsequent periods. We applied a non-convertible debt borrowing rate of 7.125% upon adoption of these new rules based on quoted market prices for our 6.125% senior notes due 2014 on the date the convertible senior notes were issued. The impact of this requirement has resulted in a material increase to our non-cash OID interest expense for financial statements covering the periods ended December 31, 2006 through December 31, 2013. The additional interest costs are being amortized over the period ending November 15, 2013, which is the date that the convertible senior notes are first putable by the convertible note holders. 42 Results of Operations The tables below set forth, by segment, the average dayrates, utilization rates and effective dayrates for our vessels and the average number and size of vessels owned during the periods indicated. These new generation OSVs and tank barges generate substantially all of our revenues and operating profit. Excluded from the OSV information below is the results of operations for our MPSVs, conventional vessels, our shore-base facility, and vessel management services. We have excluded MPSV results because fiscal years 2010, 2009, and 2008 were introductory operating years for these vessels.

Our average number of new generation OSVs for the years ended December 31, 2010, 2009 and 2008 reflect the deliveries of several vessels under our fourth OSV newbuild program. During 2010, 2009 and 2008, we placed in service, four OSVs, eight OSVs and four OSVs, respectively. Please refer to the New Generation OSVs table on page 6 of this Form 10-K for more information about vessel names and placed in service dates. Excluded from this data are ten conventional OSVs that were also acquired in August 2007, nine of which were sold on various dates since 2008. We consider our remaining conventional OSV to be a non-core asset. In response to weak market conditions, we elected to stack certain of our new generation OSVs on various dates in 2009 and 2010. Active new generation OSVs represent vessels that are fully crewed and immediately available for service during each respective period. (2) (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, crewing services and net brokerage revenues, based on the number of days during the period that the OSVs generated revenue. (5) Effective dayrate represents the average dayrate multiplied by the average utilization rate. (6) Other operating data for tugs and tank barges reflects only the results from our double-hulled tank barges as our single-hulled tank barges are considered non-core assets. Our active Downstream fleet was comprised of nine double-hulled barges and nine ocean-going tugs. (7) 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 is equal to the cost paid by customers of in-chartering third-party equipment. (8) Effective utilization rate is based on a denominator comprised only of vessel-days available for service by the active fleet, which excludes the impact of stacked vessel days. 43 YEAR ENDED DECEMBER 31, 2010 COMPARED TO YEAR ENDED DECEMBER 31, 2009 Summarized financial information concerning our reportable segments for the years ended December 31, 2010 and 2009, respectively, is shown below in the following table (in thousands, except percentage changes): Year Ended December 31, Increase (Decrease) 2010 2009 $ Change % Change Revenues by segment: Upstream Domestic . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $298,400 $274,782 51,875 Foreign . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 76,127 $ 23,618 24,252 374,527 326,657 47,870 8.6% 46.8 14.7 Downstream Domestic . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Included in depreciation and amortization, for the year ended December 31, 2009, is a pre-tax non-cash asset impairment charge of $25.8 million related to ten single-hulled tank barges and six ocean-going tugs as well as a $0.9 million pre-tax non-cash charge for the write-off of remaining goodwill associated with this segment. 44 Revenues. Revenues for 2010 increased by $34.9 million, or 9.0%, to $420.8 million compared to 2009 primarily due to the full and partial-period contribution of newbuild and converted Upstream vessels that were added to our fleet since January 1, 2009. Although we added 14 vessels to our fleet since early 2009, our weighted-average active operating fleet as of December 31, 2010 was approximately 65 vessels compared to 66 vessels for the same period in 2009 as a result of vessels that were stacked, sold or retired during 2009 and 2010. Revenues from our Upstream segment increased by $47.9 million, or 14.7%, to $374.5 million for 2010 compared to $326.7 million for 2009. The vessels placed in service under our newbuild and conversion programs accounted for a $98.5 million increase in Upstream revenues. These incremental revenues were offset by an $18.3 million decrease in revenue primarily from lower effective dayrates for our new generation OSVs that were in service during each of the years ended December 31, 2010 and 2009 and a $32.3 million decrease in revenue for our new generation and conventional OSVs that were in service during 2009, but have either been stacked or sold on various dates since then and decreased activity at our shore-base port facility. Our new generation OSV average dayrates of $21,561 for 2010 were in-line with dayrates of $21,348 for 2009. Our new generation OSV dayrates for the year ended December 31, 2010 were favorably impacted by non-recurring revenues for one of our specialty service vessels unrelated to the oil spill relief efforts in the GoM. Excluding these revenues, our new generation OSV dayrates would have been $20,756, or 2.7% lower than the prior-year. This decrease in dayrates is largely due to contracts that expired in 2009 and early 2010 having terms that were negotiated during stronger OSV market conditions. Several OSV time charter contracts that were in effect during 2009 and previously fixed in 2008 at dayrates in the range of $20,000 to $36,000 were replaced or renewed with spot time charters at dayrates that were roughly 50% lower than their previously contracted rates. Our new generation OSV utilization was 71.6% compared to 79.9% for 2009. The decline in utilization was driven by weaker GoM OSV market conditions over the last 12 months, which was further exacerbated by the federal drilling moratorium and de facto regulatory moratorium in the deepwater GoM. In addition, we had 962 incremental days out-of-service to ready eight OSVs for long-term charters in Latin America. Domestic revenues for our Upstream segment increased $23.6 million during the year ended December 31, 2010 due to the full or partial- period contribution of eleven additional OSVs and three additional MPSVs that were placed in service on various dates since January 1, 2009. This increase was partially offset by an average of 7.5 new generation OSVs being stacked during 2010 compared to an average of 4.1 new generation OSVs being stacked during 2009. Foreign revenues for our Upstream segment increased $24.3 million due to five additional vessels deployed to foreign markets since 2009. For the year ended December 31, 2010, oil spill response activities accounted for approximately $89.6 million of our Upstream revenues. Revenues from our Downstream segment decreased by $13.0 million, or 21.9%, to $46.3 million for 2010 compared to 2009. The partial-period revenue contribution from single-hulled tank barges that were in service during the year ended December 31, 2009, but have been retired, stacked or sold since then, accounted for $9.6 million of the Downstream revenue decline. The remaining $3.4 million decrease in Downstream revenues was largely due to well-test contract cancellation fees recognized during 2009. Such fees typically represent customer revenue that we would have otherwise earned over a contract term for specialty services contracts. Well-test contract cancellations are not uncommon for these types of high profile specialty service projects and will likely occur again in the future. However, we had no 45 such well-test contract cancellations during 2010. Excluding the well-test contract cancellation revenues, our Downstream revenues for the year ended December 31, 2010 would have decreased $7.6 million, or 12.8% from the year ended December 31, 2009. Our Downstream revenues for 2010 were favorably impacted by one of our double-hulled tank barges performing well-test services for an Upstream customer in the GoM and having up to five double-hulled tank barges temporarily contracted by BP to support oil skimming operations in the GoM. Our double-hulled tank barge average dayrates were $17,502 for the year ended December 31, 2010, a decrease of $3,636, or 17.2%, from $21,138 for 2009. Excluding the incremental revenues associated with well-test revenue in 2010 and 2009, double-hulled tank barge average dayrates would have been $16,640 and $18,840, respectively. Our double- hulled tank barge utilization was 80.5% for 2010 compared to 71.5% for 2009. The increase in double-hulled tank barge utilization was primarily driven by the temporary increase in demand related to our oil spill recovery efforts in the GoM during 2010. For the year ended December 31, 2010, oil spill response activities accounted for approximately $12.5 million of our Downstream revenues. Operating expenses. Operating expenses for 2010 increased by $35.6 million, or 22.1%, to $196.8 million. This increase was primarily associated with adding eleven new generation OSVs and three MPSVs to our active fleet since 2009 under our fourth OSV newbuild program and MPSV program, respectively. Through vessel sales or stacking, we have partially offset these higher operating costs by removing Upstream and Downstream equipment from our operating fleet. Operating expenses for our Upstream segment were $166.3 million, an increase of $44.9 million, or 36.9%, for 2010 compared to $121.5 million for 2009. Newly constructed vessels placed in service since 2009 accounted for approximately $38.7 million of the higher operating costs. Vessels that operated during the years ended December 31, 2009 and 2010 accounted for approximately $18.5 million of the operating expense variance, which primarily resulted from pre-positioning costs for vessels operating in Latin America. Included in these pre-positioning costs was industry-wide Brazilian importation and regulatory review delays which resulted in higher than expected days out-of-service, and mobilization costs of approximately $9.7 million associated with placing eight vessels on charter in Brazil. These increases were partially offset by approximately $12.3 million in operating expense decreases resulting from a reduction of our operating fleet through vessel sales or stacking and decreased activity at our shore-base port facility. Excluding vessels that were mobilizing to Brazil, operating expenses were flat for vessels that were in-service during all of 2009 and 2010. Aggregate cash operating expenses for our Upstream segment are projected to be in the range of $140.0 million and $145.0 million for 2011, inclusive of approximately $3.3 million expected to be incurred for our 15 inactive stacked OSVs. With 15 new generation OSVs projected to be stacked throughout 2011, our active Upstream Fleet for 2011 is expected to be comprised of 36 new generation OSVs and four MPSVs. These 36 new generation OSVs are comprised of 23 “term” vessels that are currently chartered on long-term contracts with maturities extending beyond 2011 and 13 “spot” vessels that are currently idle or operating under short-term charters. All four of our MPSVs are currently idle or operating under short- term charters. Our cash operating expense estimate is exclusive of any additional repositioning expenses we may incur that are not recoverable through charter hire in connection with the potential relocation of more of our vessels into international markets; or any customer-required cost-of-sales related to future contract fixtures that are typically 46 recovered through higher dayrates. Also excluded from these projected Upstream operating costs for 2011 are potential late-delivery penalties resulting from Brazilian importation and regulatory review delays noted above. Operating expenses for our Downstream segment were $30.4 million, a decrease of $9.3 million, or 23.4%, for the year ended December 31, 2010 compared to $39.7 million for the same period in 2009. The decrease in operating expenses for the Downstream segment is primarily associated with the lower cost of maintaining equipment that was stacked, sold or retired from service since 2009. Operating expenses for our active nine double-hulled tank barges and associated tugs was down approximately $2.6 million in the year ended 2010 compared to 2009. Aggregate cash operating expenses for our Downstream segment are projected to be in the range of $28.0 million to $30.0 million for 2011. Depreciation and Amortization. Depreciation and amortization was $16.3 million lower for 2010 compared to 2009 due to the $26.7 million asset and goodwill impairment charges for our Downstream segment recorded during the second quarter of 2009. In addition, we incurred incremental depreciation in 2010 related to eleven OSVs placed in service under our fourth OSV newbuild program and three MPSVs placed in service under our MPSV program since 2009. Depreciation and amortization expense is expected to increase further when these and any other recently acquired and newly constructed vessels undergo their initial 30-month and 60-month recertifications. General and Administrative Expense. General and administrative expenses of $36.8 million, or 8.7% of revenues, increased by $5.9 million during the year ended December 31, 2010 compared to the year ended December 31, 2009. This increase is primarily the result of higher personnel and stock-based compensation expense costs recorded during 2010 compared to 2009. Our general and administrative expenses for 2011 are expected to be in the range of $35.0 million to $39.0 million for 2011. Gain on Sale of Assets. During 2010, we sold two conventional OSVs, one older, lower- horsepower tug, and two single-hulled tank barges for net cash proceeds of $4.5 million for these vessel sales, which resulted in aggregate gains of approximately $1.9 million ($1.2 million after tax or $0.04 per diluted share). During 2009, we sold one older, lower- horsepower tug, six single-hulled tank barges, and three conventional OSVs for net cash proceeds of $10.6 million. We recorded aggregate gains of approximately $1.1 million ($0.7 million after tax or $0.03 per diluted share) on the sales of these vessels. Operating Income. Operating income increased by $10.5 million, or 10.4%, to $112.2 million during the year ended December 31, 2010 compared to the same period in 2009 due to the reasons discussed above. Operating income as a percentage of revenues for our Upstream segment was 29.5% for 2010 compared to 39.5% for the 2009. The primary driver for this margin decrease relates to operating costs associated with the mobilization of eight vessels to Latin America. We recorded operating income of $1.7 million for our Downstream segment for 2010, compared to operating loss of $27.2 million for 2009. Excluding the asset and goodwill impairment charges noted above, the Downstream segment operating loss for the year ended December 31, 2009 would have been $0.5 million. Interest Expense. Interest expense increased $34.2 million during the year ended December 31, 2010 compared to the same period in 2009. This increase was driven by 47 incremental interest resulting from our 8.000% senior notes due 2017, which were issued in August 2009, and lower capitalized interest driven by having fewer vessels under construction in our newbuild and conversion programs. See “Liquidity and Capital Resources” for further discussion. Interest Income. Interest income increased 9.5% during 2010 compared to 2009. The average interest rate earned on our invested cash balances during the year ended December 31, 2010 was approximately 0.6% compared to 1.1% for the same period in 2009. Although we earned lower rates on our invested cash balances, our average cash balance increased to $82.7 million for 2010 compared to $36.2 million for 2009. Income Tax Expense. Our effective tax rate was 37.1% and 37.4% for the year ended December 31, 2010 and 2009, respectively. Our income tax expense primarily consists of deferred taxes. Our income tax rate is higher than the federal statutory rate primarily due to expected state tax liabilities and items not deductible for federal income tax purposes. We expect our annual effective tax rate to be in the range of 35.0% to 37.0% in 2011. Net Income. Net income decreased by $14.0 million, or 27.7%, to $36.4 million for the year ended December 31, 2010 compared to the same period in 2009 primarily due to a $34.1 million pre-tax increase in net interest expense. 48 YEAR ENDED DECEMBER 31, 2009 COMPARED TO YEAR ENDED DECEMBER 31, 2008 Summarized financial information concerning our reportable segments for the years ended December 31, 2009 and 2008, respectively, is shown below in the following table (in thousands, except percentage changes): Revenues by segment: Upstream Domestic . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $274,782 $262,199 72,161 Foreign . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 51,875 $ 12,583 (20,286) 4.8% (28.1) Year Ended December 31, Increase (Decrease) 2009 2008 $ Change % Change Downstream Domestic . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Revenues for 2009 decreased 10.7%, or $46.1 million, to $385.9 million from 2008 primarily due to a decline in effective, or utilization-adjusted, dayrates for both our Upstream and Downstream segments. These lower dayrates were partially offset by the full and partial-period contribution of Upstream vessels that were added to our fleet since December 31, 2007. For the year ended December 31, 2009, our weighted-average active fleet, including our Upstream and Downstream vessels, was approximately 66 vessels compared to 80 vessels for the same period in 2008. Revenues from our Upstream segment decreased $7.7 million, or 2.3%, to $326.7 million for 2009 compared to $334.4 million for 2008. The vessels placed in service under our newbuild and conversion programs accounted for a $46.1 million increase in Upstream revenues. This increase was more than offset by a $34.0 million decrease in revenue from lower effective dayrates for our new generation OSVs that were in service during each of the years ended December 31, 2009 and 2008 and a $19.8 million decrease in revenue from our conventional OSVs that were in service during 2008, but have either been stacked or sold on various dates since then. Our new generation OSV average dayrate was $21,348 in 2009 compared to $22,939 in 2008, a decrease of $1,591 or 6.9%. Our new generation OSV utilization was 79.9% compared to 95.4% in 2008. Our new generation OSV dayrates were driven lower by slack demand for our services resulting from decreased drilling and production activity in the markets in which we operate. Domestic revenues for our Upstream segment increased $12.6 million during 2009 on the basis of our fleet growth, offset by decreased dayrates and utilization. Foreign revenues for our Upstream segment decreased by $20.3 million primarily due to the mobilization of three new generation OSVs from Latin America to the GoM during 2009. However, we mobilized four new generation OSVs back to Latin America from the GoM in December 2009. Revenues from our Downstream segment decreased $38.4 million, or 39.3%, to $59.3 million for 2009 compared to 2008. The decrease in revenues was driven by soft market conditions that led to our decision to stack all of our single-hulled tank barges and six lower horsepower tugs on various dates since April 30, 2008. The decrease in revenues was partially offset by incremental revenues generated by well-test contract cancellation fees recognized during 2009 and the full-period contribution from one newbuild double-hulled tank barge, the Energy 6508, which was placed in service in March 2008. Well-test contract cancellation fees typically represent customer revenue that we would have otherwise earned over a contract term for specialty services contracts. Such fees are not uncommon for these types of high profile specialty service projects and will likely occur again in the future. Our double-hulled tank barge average dayrate was $21,138 in 2009, a decrease of $668, or 3.1%, from $21,806 in 2008. Our double-hulled tank barge utilization was 71.5% for 2009 compared to 85.0% for 2008. The decrease in double-hulled tank barge utilization was driven by reduced demand for petroleum products in the U.S., which we attributed to the depressed state of the economy in 2009. During the fourth quarter of 2009, six of these stacked vessels were sold. Foreign revenues for our Downstream segment decreased $8.2 million primarily due to fewer vessels operating in Puerto Rico during 2009 compared to the same period in 2008. Operating expenses. Operating expenses for 2009 decreased by $3.3 million, or 2.0%, to $161.2 million. This decrease reflects the reduced costs associated with removing from our active operating fleet, through vessel sales or stacking, eight new generation OSVs, six conventional OSVs, six single-hulled barges and six ocean-going tugs since the end of 2008. 50 These fleet reductions were partially offset by the incremental operating costs associated with adding eight new generation OSVs and two MPSVs to our active fleet since 2008 under our fourth OSV newbuild program and MPSV program, respectively. Daily vessel operating costs for 2009 were in-line with 2008 for vessels that operated in both of our segments during 2009 and 2008. Operating expenses for our Upstream segment were $121.5 million, an increase of $10.2 million, or 9.2%, for 2009 compared to $111.3 million for 2008. Newly constructed vessels placed in service since 2008 accounted for approximately $18.5 million of increased operating expenses during 2009. Excluding the impact of the recent newbuild deliveries, operating expense decreased approximately $8.3 million from 2008 primarily due to the stacking of eight new generation OSVs and the sale or stacking of our conventional OSVs on various dates during 2008 and 2009. Operating expenses for our Downstream segment were $39.7 million, a decrease of $13.6 million, or 25.5%, for 2009 compared to 2008. The decrease in operating expenses for the Downstream segment is primarily associated with the lower cost of maintaining equipment that was stacked, sold or retired from service since 2008. Depreciation and Amortization. Depreciation and amortization was $41.4 million higher for 2009 compared to 2008, substantially due to an asset impairment charge for our Downstream vessels. During the second quarter of 2009, we recorded an asset impairment of $25.8 million, or $0.60 per diluted share, related to the write-down of ten of our single-hulled tank barges and six of our ocean-going tugs to their respective fair values. In addition, we incurred incremental depreciation related to eight OSVs placed in service under our fourth OSV newbuild program and two MPSVs placed in service under our MPSV program since 2008. Our depreciation and amortization expense for 2009 also included an approximate $0.9 million, or $0.02 per diluted share, charge for the write-off of remaining goodwill associated with our Downstream segment, which was also recorded during the second quarter of 2009. General and Administrative Expenses. General and administrative expenses of $30.8 million, or 8.0% of revenues, decreased by $6.3 million during 2009 compared to 2008. This decrease is due to lower shore-side incentive compensation and stock-based compensation expense. Gain on Sale of Assets. During 2009, we sold an older, lower-horsepower tug, six single- hulled tank barges and three conventional OSVs for net cash proceeds of $10.6 million. We recorded aggregate gains of approximately $1.1 million ($0.7 million after-tax or $0.03 per diluted share) on the sales of these vessels. In 2008, we sold four conventional OSVs for net cash proceeds of $17.8 million for an aggregate gain of $8.4 million ($5.3 million after-tax or $0.20 per diluted share). Operating Income. Operating income decreased by $85.1 million, or 45.6%, to $101.7 million during 2009 compared to 2008 due to the reasons discussed above. Operating income as a percentage of revenues for our Upstream segment was 39.5% for 2009 compared to 51.5% for 2008. The primary driver for this margin decrease relates to lower effective dayrates and lower utilization for our Upstream equipment during 2009 compared to 2008 and higher gains from vessel sales recorded in 2008. We recorded an operating loss of $27.2 million for our Downstream segment for 2009, compared to operating income of $14.5 million 51 for 2008. This decrease primarily relates to the $26.7 million impairment losses discussed above and lower dayrates and utilization for Downstream equipment during 2009. Interest Expense. Interest expense increased $12.7 million during 2009 compared to 2008. Our interest expense variance was driven by incremental interest resulting from our newly issued 8.000% senior notes due 2017 and lower capitalized interest driven by having fewer vessels under construction in our newbuild and conversion programs. See “Liquidity and Capital Resources” for further discussion. Interest Income. Interest income decreased by $1.0 million to $0.5 million during 2009 largely due to lower invested cash balances. The decrease in invested cash balances was driven by cash paid for newbuild and conversion programs. Our weighted-average cash balance for 2009 was $36.2 million compared to $43.0 million for 2008. The average interest rate earned on our invested cash balances during the year ended December 31, 2009 was 1.1% compared to 3.2% for 2008. Income Tax Expense. Our effective tax rate was 37.4% and 35.7% for 2009 and 2008, respectively. Our effective rate increased mainly due to a larger effect of permanent book-tax differences on our lower pre-tax income. Our income tax expense primarily consists of deferred taxes. Our income tax rate is higher than the federal statutory rate primarily due to expected state tax liabilities and items not deductible for federal income tax purposes. Net Income. Net income decreased by $65.4 million, or 56.5%, to $50.4 million for 2009 compared to 2008. This decrease was primarily due to the lower operating income discussed above, as well as a $13.7 million increase in net interest expense. Liquidity and Capital Resources Our capital requirements have historically been financed with cash flows from operations, proceeds from issuances of our debt and common equity securities, borrowings under our credit facilities and cash received from the sale of assets. We require capital to fund on-going operations, vessel construction, retrofit or conversion projects, acquisitions, vessel recertifications, discretionary capital expenditures and debt service. The nature of our capital requirements and the types of our financing sources are not expected to change significantly throughout 2011. While we have postponed required drydockings for some of our stacked vessels, we will be required to conduct any deferred drydockings prior to such vessels returning to service. The drydocking funds required to recertify currently stacked vessels will be dependent upon vessel class, certification requirements and the timing and sustainability of any market recovery. We have reviewed all of our debt agreements as well as our liquidity position and projected future cash needs. Despite volatility in financial and commodity markets, we remain confident in our current financial position, the strength of our balance sheet and the short- and long-term viability of our business model. To date, our liquidity has not been materially impacted and we do not expect that it will be materially impacted in the near-future due to such volatility. We believe that our cash on-hand, projected operating cash flow and available borrowing capacity under our recently amended revolving credit facility will be more than sufficient to operate the Company, while we reposition vessels to alternative markets and/or await the resumption of drilling activities in the GoM. 52 Although we expect to continue generating positive working capital through our operations, events beyond our control, such as an extended delay in returning to normal operating conditions following the de facto regulatory moratorium in the GoM, declines in expenditures for exploration, development and production activity, mild winter conditions or any extended reduction in domestic consumption of refined petroleum products and other reasons discussed under “Forward Looking Statements” on page 1 and the Risk Factors stated in Item 1A of this Annual Report on Form 10-K, may affect our financial condition or results of operations. None of our debt instruments mature any sooner than March 2013. Depending on the market demand for our vessels, long-term debt maturities and other growth opportunities that may arise, we may require additional debt or equity financing. We currently expect to generate sufficient cash to re-pay our long-term debt upon maturity. However, it is possible that, due to events beyond our control, including those described in our Risk Factors, should such need for additional financing arise, we may not be able to access the capital markets on attractive terms at that time or otherwise obtain sufficient capital to meet our maturing debt obligations or finance growth opportunities that may arise. We will continue to closely monitor our liquidity position, as well as the state of the global capital and credit markets. As of December 31, 2010, we had total cash and cash equivalents of $127.0 million. During 2009, we used the majority of the net proceeds from a private placement of 8.000% senior notes to pay the then-outstanding $200.0 million balance drawn under our revolving credit facility. In addition, in late 2009 we subsequently amended and extended our revolving credit facility to include an accordion feature that allows for the expansion of the facility up to an aggregate of $350.0 million as discussed in Note 6 to our consolidated financial statements. On March 14, 2011, we amended the credit agreement governing our revolving credit facility to adjust certain financial ratios and maintenance covenants to provide greater financial flexibility in light of the current market uncertainty in the GoM. The revolving credit facility as of March 15, 2011 remains undrawn. Excluding any potential cash requirements for growth opportunities that may arise, our cash on-hand of $127.0 million as of December 31, 2010 and our internal cash projections indicate that our revolving credit facility will remain undrawn for the foreseeable future beyond 2011. As of December 31, 2010, we had a posted letter of credit for $0.9 million and, subsequent to the March 2011 amendment, we have $249.1 million of credit available under our revolving credit facility, for all uses of proceeds, including working capital, if necessary. Prior to the March 2011 amendment, the available borrowing capacity under our revolving credit facility was largely dependent on the use of the proceeds to be drawn on such facility. See the Debt section of Commitments and Contractual Obligations on page 55 for further discussion of our recently amended revolving credit facility. Cash Flows Operating Activities. We rely primarily on cash flows from operations to provide working capital for current and future operations. Cash flows from operating activities were $131.0 million in 2010, $183.2 million in 2009, and $206.8 million in 2008. Operating cash flows decreased from 2009 mainly due to a decline in effective dayrates and utilization for our Upstream and Downstream segments, which was partially offset by the growth of our Upstream fleet. Cash flows from operations for 2010 reflect full and partial-period contributions from eleven additional new generation OSVs and three MPSVs that were placed in service since January 1, 2009. Cash flows from operations for 2009 reflect full- and partial- period contributions from eight additional new generation OSVs and two MPSVs that were 53 placed in service since January 1, 2008. Our cash flows from operations for 2008 reflect a full-period contribution from the OSVs that were acquired in August 2007, three additional double-hulled newbuild tank barges that were placed in service during the second half of 2007 and early 2008 and four newbuild OSVs that were placed in service in 2008. Investing Activities. Net cash used in investing activities was $57.0 million in 2010, $263.1 million in 2009, and $487.3 million in 2008. Cash utilized during 2010 primarily consisted of construction costs incurred for our newbuild and conversion programs, which were partially offset by approximately $4.7 million in aggregate net cash proceeds from the sale of two conventional OSVs, one older, lower-horsepower tug, two single-hulled barges, and other non-revenue generating equipment. Cash utilized during 2009 primarily consisted of construction costs incurred for our newbuild and conversion programs, which were partially offset by approximately $10.6 million in net cash proceeds from the sale of three conventional OSVs, six single-hulled barges and one older, lower-horsepower tug. Cash utilized in 2008 primarily consisted of construction costs incurred for our newbuild and conversion programs, as well as acquisition costs for the HOS Achiever and the lease rights for an additional shore- base facility adjacent to HOS Port. These investing activities were partially offset by approximately $17.8 million in net cash proceeds from the sale of four conventional OSVs. With the last remaining newbuild and converted vessels placed in service in 2010, our fourth OSV newbuild program and MPSV program have been completed. Financing Activities. Net cash provided by financing activities was $1.9 million in 2010, $110.6 million in 2009, and $127.1 million in 2008. Net cash provided by financing activities for 2010 primarily resulted from proceeds from common shares issued pursuant to our employee stock-based compensation plans. Net cash provided by financing activities for 2009 is primarily the result of approximately $237.3 million in net proceeds in connection with a private placement of $250.0 million in 8.000% senior notes offset by net payments on our revolving credit facility. Net cash provided by financing activities for 2008 primarily resulted from the $125.0 million in borrowings under our revolving credit facility and, to a lesser extent, the net proceeds related to common stock issued under employee benefit programs.

(2) Our 8.000% senior notes mature on September 1, 2017 and include $6,305 of original issue discount. (3) Our 1.625% convertible senior notes, with an initial interest rate of 1.625% per year, declining to 1.375% beginning on November 15, 2013, mature on November 15, 2026 and currently include $35,183 of non-cash original issue discount. Holders of the convertible senior notes may require that such notes be repurchased at their option on November 15, 2013, 2015 and 2021, pursuant to certain conditions described in Note 6 of our consolidated financial statements included herein. The debt maturities reflected in the table above assume that the holders of our convertible senior notes do not require that such notes be repurchased prior to their maturity in November 2026. 54 (4) (5) Interest payments relate to our 6.125% senior notes due December 1, 2014, our 8.000% senior notes due September 1, 2017 and our 1.625% convertible senior notes due November 15, 2026 with semi-annual interest payments of $9.2 million payable June 1 and December 1, $10.0 million payable March 1 and September 1, and $2.0 million payable May 15 and November 15, respectively. The semi-annual interest payments for our convertible senior notes will decline to $1.7 million for interest payments made after November 15, 2013. Effective January 1, 2009, we adopted new accounting standards which require us to record additional non-cash interest expense. Non-cash interest expense has been excluded from the table above. Included in operating leases are commitments for vessel rentals, a shore-base port facility, office space, office equipment and vehicles. See “—Properties” for additional information regarding our leased office space and other facilities. Debt As of December 31, 2010, we had total debt of $758.2 million, net of original issue discount of $41.8 million. Our debt is comprised of $299.7 million of our 6.125% senior notes due 2014, or 2014 senior notes, $243.7 million of our 8.000% senior notes due 2017, or 2017 senior notes, and $214.8 million of our 1.625% convertible senior notes due 2026, or convertible senior notes. The effective interest rate on the 2014 senior notes is 6.39% with semi-annual cash interest payments of $9.2 million due and payable each June 1 and December 1. The effective interest rate on the 2017 senior notes is 8.63% with semi-annual cash interest payments of $10.0 million due and payable each March 1 and September 1, commencing March 1, 2010. The $250.0 million, in face amount, of convertible senior notes bear interest at an annual coupon of 1.625% with semi-annual cash interest payments of $2.0 million due May 15 and November 15, declining to 1.375%, or $1.7 million semi-annually, beginning on November 15, 2013. The effective interest rate on such notes is 6.36%. The senior notes do not require any payments of principal prior to their stated maturity dates, but pursuant to the each indenture under which the 2014 senior notes and 2017 senior notes were issued, we would be required to make offers to purchase such senior notes upon the occurrence of specified events, such as certain asset sales or a change in control. As of December 31, 2010, we had a posted letter of credit for $0.9 million and had zero drawn on our revolving credit facility. The revolving credit facility remains undrawn as of March 15, 2011. Under our revolving credit facility, we have the option of borrowing at a variable rate of interest equal to either (i) the London Interbank Offered Rate, or LIBOR; plus an applicable margin, or (ii) the greatest of the Prime Rate, the Federal Funds Effective Rate plus 1/2 of 1% and the one-month LIBOR plus 1% plus in each case an applicable margin. The applicable margin for each base rate is determined by a pricing grid, which is based on our leverage ratio, as defined in the credit agreement governing our revolving credit facility. Unused commitment fees are payable quarterly at the annual rate of 50.0 basis points of the unused portion of the $250.0 million borrowing base of the amended facility. For additional information with respect to our revolving credit facility, our 2014 senior notes, our 2017 senior notes and our convertible senior notes, please refer to Note 6 of our consolidated financial statements included herein. On March 14, 2011, we amended the credit agreement governing our revolving credit facility to favorably adjust certain financial ratios and provide for additional new maintenance covenants. The key changes to our revolving credit facility, effective commencing with the fiscal quarter ended December 31, 2010, were as follows: (cid:129) The maximum leverage ratio, as defined in the previous credit agreement, was eliminated as a maintenance covenant and is now only used to determine the pricing grid. (cid:129) A maximum secured debt leverage ratio of 2.00 to 1.00, as defined in the March 2011 amendment, was added as a new maintenance covenant. 55 (cid:129) The minimum interest coverage ratio was reduced from 3.00 to 1.00 to 2.00 to 1.00. (cid:129) A maximum total debt to capitalization ratio of 55.0%, as defined in the March 2011 amendment, was added as a new maintenance covenant. Other than these key changes, all other definitions and substantive terms in our credit agreement governing our revolving credit facility were unchanged with the March 2011 amendment and remain in effect through the remaining life of the facility, which expires on March 31, 2013. The credit agreement governing the revolving credit facility and the indentures governing our 2014 senior notes and 2017 senior notes impose certain 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 dividend or other restricted payments. As of December 31, 2010, we were in compliance with all of our debt covenants. As of March 14, 2011, based on our financial ratios for the quarterly compliance reporting period ended December 31, 2010, the full amount of the undrawn borrowing base under our revolving credit facility is available to us for all uses of proceeds, including working capital, if necessary. We continuously review our debt covenants and report our compliance with financial ratios on a quarterly basis. We also consider such covenants in evaluating transactions that will have an effect on our financial ratios. Capital Expenditures and Related Commitments The following table sets forth the amounts incurred for our newbuild and conversion programs, before construction period interest, during the year ended December 31, 2010 and since each program’s inception, respectively, as well as the estimated total project costs for each of our current expansion programs (in millions): Growth Capital Expenditures: MPSV program(1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The first converted 370 class MPSV, the HOS Centerline, was placed in service on March 27, 2009. The first newbuild 430 class MPSV, the HOS Achiever was placed in service on October 1, 2008. The second newbuild 430 class MPSV, the HOS Iron Horse, was placed in service on November 27, 2009. With the second converted 370 class MPSV, the HOS Strongline, being placed in service on March 25, 2010, the MPSV program was completed. These actual delivery dates result in an average MPSV fleet complement of 3.8 vessels for fiscal year 2010. The aggregate cost of the MPSV program, prior to the allocation of construction period interest, was approximately $491.1 million. (2) Our fourth OSV newbuild program consisted of vessel construction contracts with three domestic shipyards to build six 240 ED class OSVs, nine 250 EDF class OSVs and one 290 class OSV. Of the 16 new generation DP-2 OSVs included in this program, we have placed in service four vessels in 2008, eight vessels in 2009, and four vessels in 2010. The last four remaining vessels the HOS Arrowhead, the HOS Pinnacle, the HOS Windancer, and the HOS Wildwing were placed in service in January 2010, February 2010, May 2010, and September 2010, respectively. These actual delivery dates result in an average new generation OSV fleet complement of 49.9 vessels for fiscal year 2010. Inclusive of the prior vessel deliveries discussed above, the aggregate cost of our fourth OSV newbuild program was approximately $431.6 million. Our fourth OSV newbuild program has been completed. 56 The following table summarizes the costs incurred, prior to the allocation of construction period interest, for the purposes set forth for the years ended December 31, 2010, 2009, and 2008 and a forecast for 2011 (in millions): Year Ended December 31, 2011 2010 2009 2008 Forecast Actual Actual Actual Maintenance and Other Capital Expenditures: Maintenance Capital Expenditures Deferred drydocking charges(1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

(2) Other vessel capital improvements include costs for discretionary vessel enhancements, which are typically incurred during a planned drydocking event to meet customer specifications. (3) Commercial-related vessel improvements includes items, such as cranes, ROVs and other specialized vessel equipment, which costs are typically included in and offset by higher dayrates charged to customers. (4) Non-vessel capital expenditures are primarily related to information technology initiatives. Inflation To date, general inflationary trends have not had a material effect on our operating revenues or expenses. 57 Item 7A—Quantitative and Qualitative Disclosures About Market Risk We have not entered into any derivative financial instrument transactions to manage or reduce market risk or for speculative purposes, other than the convertible note hedge and warrant transactions entered into concurrently with our convertible note offering in November 2006. Such transactions were entered into to mitigate the potential dilutive effect of the conversion feature of the convertible notes on our common stock. A hypothetical 25% change from our closing share price of $20.88 as of December 31, 2010 would not have an impact on such transactions. Changes in interest rates may result in changes in the fair market value of our financial instruments, interest income and interest expense. Our financial instruments that are exposed to interest rate risk are cash equivalents and long-term borrowings. Due to the short duration and conservative nature of our cash equivalent investment portfolio, we do not expect any material loss with respect to our investments. The book value for cash equivalents is considered to be representative of its fair value. A hypothetical 10% change in interest rates as of December 31, 2010 would have no material impact on such investments or interest expense. Changes in interest rates would not impact our interest expense for our long-term fixed interest rate 6.125% senior notes, 8.000% senior notes and 1.625% convertible senior notes. However, changes in interest rates would impact the fair market value of such notes. In general, the fair market value of debt with a fixed interest rate will increase as interest rates fall. Conversely, the fair market value of debt will decrease as interest rates rise. The currently outstanding 6.125% senior notes accrue interest at the rate of 6.125% per annum and mature on December 1, 2014 and the effective interest rate on such notes is 6.39%. The currently outstanding 8.000% senior notes accrue interest at a rate of 8.000% per annum and mature on September 1, 2017 and the effective interest rate on such notes is 8.63%. Our outstanding 1.625% convertible senior notes accrue interest at the rate of 1.625%, which will decline to 1.375% beginning on November 15, 2013, and mature on November 15, 2026. The effective interest rate on such notes is 6.36%. In connection with our convertible notes, we are a party to convertible note hedge transactions with respect to our common stock with Jefferies & Company, Inc., Bear Stearns International Limited and AIG-FP Structured Finance (Cayman) Limited, or the counterparties. As a result of the financial markets crisis during the third quarter of 2008, the Bear Stearns International Limited position has been assumed by JPMorgan Chase in its acquisition of Bear Stearns and AIG-FP Structured Finance (Cayman) Limited’s parent company, or AIG, was re-capitalized by the U.S. Government. We are not currently aware of any collection issues with regard to any of these counter-parties. We estimate the fair value of our 6.125% senior notes due 2014, our 8.000% senior notes due 2017 and our 1.625% convertible senior notes due 2026, all of which are publicly traded, by using quoted market prices. The fair value of our revolving credit facility, when there are outstanding balances, approximates its carrying value. The face value, carrying value and fair value of our total debt was $800.0 million, $758.2 million and $783.9 million, respectively, as of December 31, 2010. As of December 31, 2010, we had no amounts outstanding under our revolving credit facility. Therefore it is not subject to interest rate risk. 58 Our operations are primarily conducted between U.S. ports, including along the coast of Puerto Rico, and historically we have not been exposed to significant foreign currency fluctuation. However, as we expand our operations in international markets, we may become exposed to certain risks typically associated with foreign currency fluctuation. We currently have time charters for 13 of our OSVs for service offshore Latin America. Although such contracts are denominated and will be paid in U.S. Dollars, value added tax, or VAT, payments are paid in local currencies which creates an exchange risk related to currency fluctuations. There is an exchange risk to foreign currency fluctuations related to the payment terms of such time charters. We also frequently acquire other vessel equipment for our active vessels that are denominated in foreign currencies, which creates an exchange risk to foreign currency fluctuations related to the payment terms of such commitments or purchases. To date, we have not hedged against any foreign currency rate fluctuations associated with foreign currency VAT payments or other foreign currency denominated transactions arising in the normal course of business. We continually monitor the currency exchange risks associated with conducting international operations. To date, gains or losses associated with such fluctuations have not been material. Item 8—Financial Statements and Supplementary Data The financial statements and information required by this Item appear on pages F-1 through F-27 of this Annual Report on Form 10-K. Item 9—Changes in and Disagreements with Accountants on Accounting and Financial Disclosures None. Item 9A—Controls and Procedures Disclosure Controls and Procedures Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. Internal Control Over Financial Reporting Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13(a)-15(f) or Rule15d-15(f) under the Exchange Act. Internal control over financial reporting is a process to 59 provide reasonable assurance regarding the reliability of our financial reporting for external purposes in accordance with U.S. generally accepted accounting principles. Internal control over financial reporting includes maintaining records that, in reasonable detail, accurately and fairly reflect our transactions; providing reasonable assurance that transactions are recorded as necessary for preparation of our financial statements in accordance with U.S. generally accepted accounting principles; providing reasonable assurance that receipts and expenditures of company assets are made in accordance with authorizations of the Company’s management and board of directors; and providing reasonable assurance that unauthorized acquisition, use or disposition of company assets that could have a material effect on our financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies of procedures may deteriorate. Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2010, utilizing the criteria set forth in the report entitled Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based upon such assessment, our management concluded that our internal control over financial reporting was effective as of December 31, 2010. Ernst & Young LLP, an independent registered public accounting firm, who audited our consolidated financial statements included in this Form 10-K, has issued an attestation report on our internal control over financial reporting which is included herein. There were no changes in our internal controls over financial reporting that occurred during the quarter ended December 31, 2010 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 60 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Stockholders Hornbeck Offshore Services, Inc. We have audited Hornbeck Offshore Services, Inc.’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control— Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Hornbeck Offshore Services, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, Hornbeck Offshore Services, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Hornbeck 61 Offshore Services, Inc. and subsidiaries as of December 31, 2010 and 2009, and the related consolidated statements of operations, changes in stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2010 of Hornbeck Offshore Services, Inc. and subsidiaries and our report dated March 16, 2011 expressed an unqualified opinion thereon. /s/ Ernst & Young LLP New Orleans, Louisiana March 16, 2011 Item 9B—Other Information On March 14, 2011, two of our subsidiaries, Hornbeck Offshore Services, LLC and Hornbeck Offshore Transportation, LLC, as borrowers, and we, as guarantor, amended the agreement governing our existing senior secured revolving credit facility with Wells Fargo Bank, N.A., as administrative agent, and the lenders party thereto to adjust certain financial ratios and maintenance covenants.

F-7 F-1 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Stockholders Hornbeck Offshore Services, Inc. We have audited the accompanying consolidated balance sheets of Hornbeck Offshore Services, Inc. and subsidiaries as of December 31, 2010 and 2009, and the related consolidated statements of operations, changes in stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2010. 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 conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (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 balance sheets of Hornbeck Offshore Services, Inc. and subsidiaries at December 31, 2010 and 2009, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles.

F-6 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. Organization Nature of Operations Hornbeck Offshore Services, Inc., or the Company, was incorporated in the state of Delaware in 1997. The Company, through its subsidiaries, operates offshore supply vessels, or OSVs, multi-purpose support vessels, or MPSVs, and a shore-base facility to provide logistics support and specialty services to the offshore oil and gas exploration and production industry, primarily in the U.S. Gulf of Mexico, or GoM, and select international markets. The Company, through its subsidiaries, also operates ocean-going tugs and tank barges that provide transportation of petroleum products, primarily in the northeastern United States, GoM and Puerto Rico. All significant intercompany accounts and transactions have been eliminated. 2. Summary of Significant Accounting Policies Revenue Recognition The Company charters its OSVs, MPSVs and certain of its tank barges 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. The Company also contracts certain of its tank barges to clients under contracts of affreightment, or COAs, under which revenue is recognized based on the number of days incurred for the voyage as a percentage of 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. Deferred revenue represents payments received from customers or billings submitted to customers in advance of vessels commencing time charters. Cash and Cash Equivalents Cash and cash equivalents consist of all highly liquid investments in money market funds, deposits and investments available for current use with an initial maturity of three months or less. Accounts Receivable Accounts receivable consists of trade receivables net of reserves, amounts to be rebilled to customers and interest receivables. Property, Plant and Equipment Property, plant and equipment is 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. Major modifications and improvements, F-7 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) which extend the useful life of the vessel, are capitalized and amortized over the remaining useful life of the vessel. Gains and losses from retirements or other dispositions are recognized as incurred. Salvage values for marine equipment are estimated to range between 5% and 25% of the originally recorded cost, depending on the vessel type. The estimated useful lives by classification are as follows: Tugs . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Non-vessel related property, plant and equipment 14-25 years 3-25 years 5-25 years 25 years 3-28 years All of the Company’s single-hulled tank barges have estimated useful lives based on their classification under the Oil Pollution Act of 1990. The Company’s double-hulled tank barges have an estimated useful life of 25 years. Assets having shorter useful lives primarily relate to acquired vessels. See “Impairment of Long-Lived Assets” below for more information. Deferred Charges The Company’s vessels are required by regulation to be recertified after certain periods of time. The Company defers the drydocking expenditures incurred due to regulatory marine inspections and amortizes the costs on a straight-line basis over the period to be benefited from such improvements (generally 30 months). Financing charges are amortized over the term of the related debt. Deferred charges also include prepaid lease expenses related to the Company’s shore- base port facility. Such prepaid lease expenses are being amortized on a straight-line basis over the effective remaining term of the lease. Mobilization Costs The Company incurs mobilization costs to transit its vessels to and from certain regions and/or for long-term contracts. These costs, which are typically expensed as incurred, include, but are not limited to, fuel, crew wages, vessel modification and pre-positioning expenses, materials and supplies and importation taxes. The Company incurred mobilization costs of $9.7 million during 2010 associated with placing eight vessels on multi-year charters in Brazil Income Taxes 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 F-8 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) the period that includes the enactment date. The provision for income taxes includes provisions for federal, state and foreign income taxes. Interest and penalties relating to uncertain tax positions are recorded as general and administrative expenses. Use of Estimates The preparation of financial statements in conformity with United States generally accepted accounting principles 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. The Company provides an estimate for uncollectible accounts based primarily on management’s judgment using historical losses, current economic conditions and individual evaluations of each customer to make adjustments to the allowance for doubtful accounts. The following table represents the allowance for doubtful accounts (in thousands): Balance, beginning of year . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Changes to provision . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 860 (126) $ 2,135 (1,275) $1,048 1,087 Balance, end of year . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 734 $ 860 $2,135 December 31, 2010 2009 2008 Impairment of Long-Lived 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 are 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. See Note 14 for further information 3. Earnings Per Share Basic earnings per common share was calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per common share was calculated by dividing net income by the weighted average number of common shares outstanding during the year plus the effect of dilutive stock options. Weighted F-9 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) average number of common shares outstanding was calculated by using the sum of the shares determined on a daily basis divided by the number of days in the period.

Stock options are anti-dilutive when the exercise price of the options is greater than the average market price of the common stock for the period or when the results from operations are a net loss. (2) For the year ended December 31, 2010, 2009, and 2008, the 1.625% convertible senior notes were not dilutive, as the average price of the Company’s stock was less than the effective conversion price of the Notes. See Note 6 for further information. (3) Dilutive restricted stock is expected to fluctuate from quarter to quarter depending the Company’s performance compared to a predetermined set of performance criteria. See Note 8 for further information regarding certain of the Company’s restricted stock awards. 4. Defined Contribution Plan The Company offers a 401(k) plan to all full-time employees. Employees must be at least eighteen years of age and have completed three months of service to be eligible for participation. Participants may elect to defer up to 60% of their compensation, subject to certain statutorily established limits. The Company may elect to make annual matching and profit sharing contributions to the 401(k) plan. During the years ended December 31, 2010, 2009 and 2008, the Company made contributions to the 401(k) plan of approximately $2.9 million, $2.9 million, and $2.3 million, respectively. 5.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) During 2010, the Company completed its fourth OSV newbuild program and its MPSV program. The Company’s fourth OSV newbuild program consisted of vessel construction contracts with three domestic shipyards to build six 240 ED class OSVs, nine 250 EDF class OSVs and one 290 class OSV. These vessels were delivered on various dates since 2008. The aggregate cost, prior to the allocation of construction period interest, of the fourth OSV newbuild program was approximately $431.6 million. The Company’s MPSV program consisted of the conversion of two coastwise sulfur tankers into U.S.-flagged, proprietary 370 class DP-2 new generation MPSVs at domestic shipyards, and the newbuild construction of two 430 class DP-3 new generation MPSVs at foreign shipyards. These vessels were delivered on various dates since 2008. The aggregate cost of the MPSV program, prior to the allocation of construction period interest, was approximately $491.1 million. 6. Long-Term Debt Senior Notes On November 23, 2004, the Company issued in a private placement $225.0 million in aggregate principal amount of 6.125% senior unsecured notes, or senior notes, governed by an indenture, or the 2004 indenture. The effective interest rate on the 2004 senior notes is 6.38%. On October 4, 2005, the Company issued in a private placement an additional $75.0 million in aggregate principal amount of 6.125% senior unsecured notes, or additional notes, governed by the 2004 indenture. The additional notes were priced at 99.25% of principal amount to yield 6.41%. The senior notes and additional notes, collectively, the 2014 senior notes, mature on December 1, 2014 and require semi-annual interest payments at a fixed interest rate of 6.125% per year on June 1 and December 1 of each year until maturity. No principal payments are due until maturity. Pursuant to registered exchange offers, the senior notes issued in November 2004 and October 2005 that were initially sold pursuant to private placements were exchanged by the holders for 6.125% senior notes with substantially the same terms, except that the issuance of the senior notes issued in the exchange offers was registered under the Securities Act of 1933, as amended, or the Securities Act. Both series of senior notes were issued under and are entitled to the benefits of the same 2004 indenture. On August 17, 2009, the Company issued in a private placement $250.0 million of 8.000% senior notes, or 2017 senior notes. The net proceeds to the Company from the offering were approximately $237.3 million, net of original issue discount and estimated transaction costs. The Company used $200.0 million of proceeds to repay debt under its revolving credit facility, which may be reborrowed. The remaining proceeds were available for general corporate purposes, which include partial funding of the construction of OSVs and MPSVs under existing newbuild programs. The 2017 senior notes mature on September 1, 2017 and require semi-annual interest payments at an annual rate of 8.000%, or $10.0 million semi-annually, on March 1 and September 1 of each year until maturity, which began on March 1, 2010. The effective interest rate on the 2017 senior notes is 8.63% and no principal payments are due until maturity. Pursuant to a registered exchange offer, the senior notes issued in August 2009 that were initially sold pursuant to private placements were exchanged by the holders for 8.000% senior notes with substantially the same terms, except that the F-11 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) issuance of the senior notes issued in the exchange offer was registered under the Securities Act of 1933, as amended, or the Securities Act. The original 8.000% senior notes and the similar notes exchanged therefor were issued under and are entitled to the benefits of the same 2009 indenture. The 2014 senior notes and 2017 senior notes are senior unsecured 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 that may be incurred by the Company in the future. These senior notes are guaranteed by certain of the Company’s subsidiaries. The guarantees are full and unconditional, joint and several, and all of the Company’s non-guarantor subsidiaries are minor as defined in the Securities and Exchange Commission, or Commission, regulations. Hornbeck Offshore Services, Inc., as the parent company issuer of these senior notes, has no independent assets or operations other than its ownership interest in its subsidiaries and affiliates. There are no significant restrictions on the Company’s ability or the ability of any guarantor to obtain funds from its subsidiaries by such means as a dividend or loan, except for certain restrictions contained in the Company’s revolving credit facility restricting the payment of dividends by the Company’s two principal subsidiaries. The Company may, at its option, redeem all or part of the 2014 senior notes or 2017 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. Convertible Senior Notes On November 13, 2006, the Company issued in a private placement $250.0 million of convertible senior notes due 2026, or the convertible notes, to qualified institutional buyers pursuant to Rule 144A under the Securities Act. During the first quarter of 2007, the Company registered the resale of the convertible notes by the holders thereof. The convertible notes bear interest at an annual rate of 1.625%, declining to 1.375% beginning on November 15, 2013, payable semi-annually on May 15 and November 15 of each year, with the first interest payment made on May 15, 2007. The effective interest rate on such notes is 6.36%. The convertible notes are convertible into shares of the Company’s common stock based on the applicable conversion rate only under the following circumstances: (cid:129) (cid:129) during any calendar quarter (and only during such calendar quarter), if the closing price of the Company’s shares of common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is more than 135% of the conversion price per share, which is $1,000 divided by the then applicable conversion rate; prior to November 15, 2013, during the five business day period after a 10 consecutive trading day period in which the trading price per $1,000 principal amount of senior subordinated convertible notes for each day of that period was less than 95% of the product of the closing price for the Company’s shares of common stock for each day of that period and the number of shares of common stock issuable upon conversion of $1,000 principal amount of the convertible notes; F-12 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) (cid:129) (cid:129) if the convertible notes have been called for redemption, or upon the occurrence of specified corporate transactions, as defined by the convertible note agreement. The initial conversion rate of 20.6260 shares per $1,000 principal amount of notes, which corresponds to a conversion price of approximately $48.48 per share, is based on the last reported sale price of the Company’s common shares on The New York Stock Exchange of $35.26 on November 7, 2006. As of December 31, 2010, the Company’s closing share price was $20.88. The convertible senior notes are guaranteed by certain of the Company’s subsidiaries. The guarantees are full and unconditional, joint and several, and all of the Company’s non-guarantor subsidiaries are minor as defined in Commission regulations. Hornbeck Offshore Services, Inc., as the parent company issuer of the convertible senior notes, has no independent assets or operations other than its ownership interest in its subsidiaries and affiliates. There are no significant restrictions on the Company’s ability or the ability of any guarantor to obtain funds from its subsidiaries by such means as a dividend or loan, except for certain restrictions contained in the Company’s revolving credit facility restricting the payment of dividends by the Company’s two principal subsidiaries. The convertible notes are general unsecured, senior obligations of the Company, ranking equally in right of payment with all of its existing and future senior indebtedness, including its outstanding 6.125% senior notes due 2014, 8.000% new senior notes due 2017, and indebtedness under its revolving credit facility. If, upon the occurrence of certain events, the holders of the convertible notes exercise the conversion provisions of the convertible notes, the Company may need to remit the principal balance of the convertible notes to them in cash as discussed below. In such case, the Company would classify the entire amount of the outstanding convertible notes as a current liability in the respective quarter. This evaluation of the classification of amounts outstanding associated with the convertible notes will occur every calendar quarter. Upon conversion, a holder will receive, in lieu of common stock, an amount of cash equal to the lesser of (i) the principal amount of the convertible note, or (ii) the conversion value, determined in the manner set forth in the indenture governing the convertible notes, of a number of shares equal to the conversion rate. If the conversion value exceeds the principal amount of the convertible note on the conversion date, the Company will also deliver, at the Company’s election, cash or common stock or a combination of cash and common stock with respect to the conversion value upon conversion. If conversion occurs in connection with a change of control, the Company may be required to deliver additional shares of its common stock by increasing the conversion rate with respect to such convertible notes. In connection with the sale of the convertible notes, the Company is a party to convertible note hedge transactions with respect to its common stock with Jefferies & Company, Inc., JP Morgan Chase and AIG-FP Structured Finance (Cayman) Limited, or the counterparties. Each of the convertible note hedge transactions involves the purchase of call options with F-13 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) exercise prices equal to the conversion price of the convertible notes, and are intended to mitigate dilution to the Company’s stockholders upon the potential future conversion of the convertible notes. Under the convertible note hedge transactions, the counterparties are required to deliver to the Company the number of shares of the Company’s common stock that the Company is obligated to deliver to the holders of the convertible notes with respect to the conversion. The convertible note hedge transactions cover approximately the same number of shares of the Company’s common stock underlying the convertible notes, subject to customary anti-dilution adjustments, at a strike price of approximately $48.48 per share of common stock. The convertible note hedge transactions expire at the close of trading on November 15, 2013, which is the date that the convertible notes are first putable by the convertible noteholders, although the counterparties will have ongoing obligations with respect to convertible notes properly converted on or prior to that date of which the counterparty has been timely notified. In addition, on November 15, 2016 and November 15, 2021, holders of the 1.625% convertible senior notes may require the Company to purchase their notes for cash. The Company also entered into separate warrant transactions, whereby the Company sold to the counterparties warrants to acquire approximately the same number of shares of its common stock underlying the convertible notes, subject to customary anti-dilution adjustments, at a strike price of $62.59 per share of common stock, which represented a 77.5% premium over the closing price of the Company’s shares of common stock on November 7, 2006. If the counterparties exercise the warrants, the Company will have the option to settle in cash or shares of its common stock equal to the difference between the then market price and strike price. The convertible note hedge and warrant transactions are separate and legally distinct instruments that bind the Company and the counterparties and have no binding effect on the holders of the convertible notes. For income tax reporting purposes, the Company has elected to integrate the convertible notes and the convertible note hedge transactions. Integration of the convertible note hedge with the convertible notes creates an in-substance original issue debt discount for income tax reporting purposes and, therefore, the cost of the convertible note hedge is accounted for as interest expense over the term of the convertible notes for income tax reporting purposes. The associated income tax deductions will be recognized in the period that the deduction is taken for income tax reporting purposes. The Company has also treated the proceeds from the sale of warrants as a non-taxable increase in additional paid-in capital in stockholders’ equity. Revolving Credit Facility On September 27, 2006, the Company closed on a five-year senior secured $100.0 million revolving credit facility with an accordion feature that allowed for the expansion of the facility up to an aggregate of $250.0 million. On February 20, 2008, the Company exercised its accordion feature in full and increased the then-undrawn borrowing base of its revolving credit facility from $100.0 million to $250.0 million. In accordance with the terms of F-14 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) the expanded facility, the Company pledged an additional 16 new generation OSVs as collateral commensurate with the higher borrowing base. On November 4, 2009, the Company amended and extended its revolving credit facility, which maintains its $250.0 million borrowing base but now includes an accordion feature that allows for the expansion of the facility up to an aggregate of $350.0 million. The amended facility, among other changes, also extended the maturity from September 2011 to March 2013. With the amended facility, the Company has the option of borrowing at a variable rate of interest equal to either (i) LIBOR, plus an applicable margin, or (ii) the greatest of the Prime Rate, the Federal Funds Effective Rate plus 1/2 of 1% and the one-month LIBOR plus 1%, plus in each case an applicable margin. The applicable margin for each base rate is determined by a pricing grid, which is based on the Company’s leverage ratio, as defined in the credit agreement governing the amended revolving credit facility. Unused commitment fees are payable quarterly at the annual rate of 50.0 basis points of the unused portion of the borrowing base of the amended facility. The Company also exchanged certain vessels pledged as collateral under the amended revolving credit facility such that the total number of vessels pledged as collateral is 19 new generation OSVs. None of the Company’s Downstream vessels are pledged under the amended and extended facility. As of December 31, 2010, there were no amounts drawn under the Company’s $250 million revolving credit facility and $0.9 million posted in letters of credit. As of December 31, 2010, the Company was in compliance with all financial covenants contained in its amended revolving credit facility. On March 14, 2011, the Company further amended the credit agreement governing its revolving credit facility to favorably adjust certain financial ratios and provide for additional new maintenance covenants. The key changes to the Company’s revolving credit facility, effective commencing with the fiscal quarter ended December 31, 2010, were as follows: (cid:129) The maximum leverage ratio, as defined in the previous credit agreement, was eliminated as a maintenance covenant and is now only used to determine the pricing grid. (cid:129) A maximum secured debt leverage ratio of 2.00 to 1.00, as defined in the March 2011 amendment, was added as a new maintenance covenant. (cid:129) The minimum interest coverage ratio was reduced from 3.00 to 1.00 to 2.00 to 1.00. (cid:129) A maximum total debt to capitalization ratio of 55.0%, as defined in the March 2011 amendment, was added as a new maintenance covenant. Other than these key changes, all other definitions and substantive terms in the Company’s credit agreement governing its revolving credit facility were unchanged with the March 2011 amendment and remain in effect through the remaining life of the facility, which expires on March 31, 2013. The credit agreement governing the amended revolving credit facility and the indentures governing the Company’s 2014 senior notes and 2017 senior notes impose certain operating and financial restrictions on the Company. Such restrictions affect, and in many cases limit or prohibit, among other things, the Company’s ability to incur additional indebtedness, make capital expenditures, redeem equity, create liens, sell assets and make dividend or other restricted payments. F-15 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) The Company estimates the fair value of its 6.125% senior notes due 2014, its 8.000% senior notes due 2017 and its 1.625% convertible senior notes due 2026 by using quoted market prices. The fair value of the Company’s revolving credit facility, when there are outstanding balances, approximates its carrying value. The face value, carrying value and fair value of the Company’s total debt was $800.0 million, $758.2 million and $783.9 million, respectively, as of December 31, 2010. Interest expense excludes capitalized interest related to the construction or conversion of vessels in the approximate amount of $3.7 million, $23.8 million, and $28.3 million, for the years ended December 31, 2010, 2009, and 2008, respectively.

Stockholders’ Equity Preferred Stock The Company’s certificate of incorporation authorizes 5.0 million shares of preferred stock. The Board of Directors has the authority to issue preferred stock in one or more series F-16 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) 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 stockholders. Stockholder Rights Plan The Company’s Board of Directors previously implemented a stockholder rights plan, as amended, establishing one right for each outstanding share of common stock. The rights 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, 10% or more of the Company’s common stock. 8. Stock-Based Compensation Incentive Compensation Plan During the Company’s Annual Meeting of Stockholders in June 2010, the Company’s stockholders approved an increase in the number of shares available to issue under its stock- based incentive compensation plan by 700,000. The Company’s stock-based incentive compensation plan now covers a maximum of 4.2 million shares of common stock that allows the Company to grant restricted stock awards, restricted stock unit awards, or collectively restricted stock, stock options and stock appreciation rights to employees and directors. The issuance of shares of common stock under the incentive compensation plan has been registered on Form S-8 with the Securities and Exchange Commission. The table below reflects selected financial captions and the related impact stock-based compensation expense charges have on the Company’s operating results (in thousands, except per share data): Year Ended December 31, 2010 2009 2008 Income before taxes . . . . . . . . . . . . . . . . . . . . . . . . . . . $8,710 $8,704 $10,815 Net income . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $5,479 $5,449 $ 6,954 Earnings per common share: Basic . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 0.21 $ 0.21 $ 0.27 Diluted . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 0.20 $ 0.20 $ 0.26 For the years ended December 31, 2010, 2009, and 2008, approximately $0.4 million, $1.1 million, and $1.4 million of stock-based compensation expense, respectively, was capitalized as part of the Company’s newbuild construction programs and general corporate projects. The accounting rule also requires the benefits of tax deductions in excess of recognized compensation expense to be reported as financing cash flows, rather than as operating cash flows. The Company recorded financing cash flows for such excess tax F-17 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) deductions of approximately $0.4 million, $0.2 million, and $0.5 million for the years ended December 31, 2010, 2009, and 2008, respectively. Net cash proceeds from the exercise of stock options were $0.6 million, $1.0 million, and $1.2 million for the years ended December 31, 2010, 2009, and 2008, respectively, and the income tax benefit from such exercises was $2.7 million, $1.3 million, and $1.0 million for the respective periods. As of December 31, 2010, the Company has approximately 1.0 million shares available for future grants of stock options, restricted stock, stock appreciation rights or other awards to employees and directors under the incentive compensation plan. Stock Options The Company is authorized to grant stock options under its incentive compensation plan in which the purchase price of the stock subject to each option is established as the closing price on the New York Stock Exchange of the Company’s common stock on the date of grant and accordingly is not less than the fair market value of the stock on the date of grant. All options granted during the year ended December 31, 2006 expire ten years after the date of grant, have an exercise price equal to or greater than the actual or estimated market price of the Company’s stock on the date of grant and vest over a one to four-year period. No stock options were granted during the years ended December 31, 2010 and 2009. The following table represents the Company’s stock option activity for the year ended December 31, 2010 (in thousands, except per share data and years): Number of Shares Weighted Average Exercise Price Weighted- Average Remaining Contractual Term (years) Options outstanding at January 1, 2010 . . . . . . . . . . .

In addition, no stock options vested during the year ended December 31, 2010. Restricted Stock The Company’s incentive compensation plan allows the Company to issue restricted stock units, with either performance-based or time-based vesting provisions. The Company has issued two types of performance-based restricted stock unit awards whose vesting is determined by achieving either external or internal performance criteria. For the first type of F-18 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) performance-based restricted stock unit award, the number of shares that will ultimately be received by the award recipients at the end of the performance period is dependent upon the Company’s performance relative to a peer group, as defined by the restricted stock unit agreements governing such awards. Performance has historically been measured by a number of factors, including the change in the Company’s stock price measured against the peer group during the measurement period, generally three years, return on invested capital, return on equity, OSV operating profit margin and growth in earnings (net income) before interest, income taxes, depreciation and amortization or EBITDA. The actual number of shares that could be received by the award recipients can range from 0% to 200% of the Company’s base share awards depending on the Company’s performance ranking relative to the peer group. This type of performance-based restricted stock unit was granted in 2008. The second type of performance-based restricted stock unit award, calculates the shares to be received based on the Company’s achievement of certain performance criteria over a three-year period as defined by the restricted stock unit agreement governing such awards. The actual number of shares that could be received by these award recipients can range from 0% to 100% of the Company’s base share awards depending on the number of performance goals attained by the Company. Compensation expense related to restricted stock unit awards is recognized over the period the restrictions lapse, from one to three years. The fair value of the Company’s performance-based restricted stock unit awards, which is determined using a Monte Carlo simulation, is applied to the base shares and is amortized over the vesting period based on either their relative performance compared to peers or internal performance goals attained. The compensation expense related to time-based restricted stock unit awards, which is amortized over a one-to-four year vesting period, is determined based on the market price of the Company’s stock on the date of grant applied to the total shares that are expected to fully vest. As of December 31, 2010, the Company had unamortized stock-based compensation expense of $7.8 million, which will be recognized over the next 1.8 years. In addition, the Company has recorded approximately $8.7 million of compensation expense during the year ended December 31, 2010 associated with restricted stock unit awards. The following table summarizes the restricted stock awards activity during the year ended December 31, 2010 (in thousands, except per share data): Number of Shares Weighted Avg.

Includes the full amount of both base and bonus share awards cancelled during the period, which represents up to 200% of the aggregate total of the base share awards. F-19 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) Employee Stock Purchase Plan On May 3, 2005, the Company established the Hornbeck Offshore Services, Inc. 2005 Employee Stock Purchase Plan, or ESPP, which was adopted by the Company’s Board of Directors and approved by the Company’s stockholders. Under the ESPP, the Company is authorized to issue up to 700,000 shares of common stock to eligible employees of the Company and its designated subsidiaries. Employees have the opportunity to purchase shares of the Company’s common stock at periodic intervals through accumulated payroll deductions that will be applied at semi-annual intervals to purchase shares of common stock at a discount from the market price as defined by the ESPP. The ESPP is designed to satisfy the requirements of Section 423 of the Internal Revenue Code of 1986, as amended, and thereby allows participating employees to defer recognition of taxes when purchasing the shares of common stock at a 15% discount under the ESPP. The Company has an effective Registration Statement on Form S-8 with the Commission registering the issuance of shares of common stock under the ESPP. As of December 31, 2010, there were approximately 425,884 shares available for future issuance to employees under the ESPP. The fair value of the employees’ stock purchase rights granted under the ESPP was estimated using the Black-Scholes model with the following assumptions for years ended December 31, 2010 and 2009: 2010 2009 Dividend yield . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Commitments and Contingencies Operating Leases The Company is obligated under certain operating leases for marine vessels, office space, shore-base facilities and vehicles. The Covington facility lease, which commenced on September 1, 2003, provides for an initial term of five years with two five-year renewal options. In September 2008, the Company exercised its first five-year renewal option. A shore-base facility lease in Port Fourchon commenced on December 20, 2005 and provides for an initial term of seven years with four additional five-year periods upon the terms and conditions contained in the lease agreement. On January 30, 2008, the Company purchased a leasehold interest in a parcel of improved real estate as an adjacent addition to HOS Port, its existing shore-base facility located in Port Fourchon, Louisiana. At December 31, 2010, the new facility lease had approximately four years remaining on its initial term, with four additional five-year renewal periods.

Total rent expense related to such leases was approximately $0.2 million, and $5.4 million, during the years ended December 31, 2009, and 2008, respectively. We did not have any rent expense related to such vessels during the year ended December 31, 2010. Contingencies In the normal course of its business, the Company becomes involved in various claims and legal proceedings in which monetary damages are sought. It is management’s opinion that the Company’s liability, if any, under such claims or proceedings would not materially affect its financial position or results of operations. The Company insures against losses relating to its vessels, pollution and third party liabilities, including claims by employees under Section 33 of the Merchant Marine Act of 1920, or the Jones Act. Third party liabilities and pollution claims that relate to vessel operations are covered by the Company’s entry in a mutual protection and indemnity F-22 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) association, or P&I Club, as well as by marine liability policies in excess of the P&I Club’s coverage. In February 2009, the terms of entry with the P&I Club for both of the Company’s segments contained an annual aggregate deductible (AAD) for which the Company remains responsible. In February 2010, the terms of entry for our Downstream segment contained an AAD. The P&I Club is responsible for covered amounts that exceed the AAD, after payment by the Company of an additional individual claim deductible. The Company provides reserves for those portions of the AAD and any individual claim deductibles for which the Company remains responsible by using an estimation process that considers Company-specific and industry data, as well as management’s experience, assumptions and consultation with outside counsel. As additional information becomes available, the Company will assess the potential liability related to its pending claims and revise its estimates. Although historically revisions to such estimates have not been material, changes in estimates of the potential liability could materially impact the Company’s results of operations, financial position or cash flows. 11.

Related Party Transactions During 2010, 2009, and 2008, the Company received aggregate payments of approximately $4.3 million, $9.9 million, and $0.6 million, respectively, for charter of its OSVs and rental of its shore-base port facility from a customer whose Chairman of the Board serves on the Company’s Board of Directors. From October 2007 until his retirement on May 7, 2009, such customer’s Chairman also served as its President and Chief Executive Officer. This Board member stepped down as Chairman of such customer and ceased to serve as a director effective May 7, 2010. F-23 HORNBECK OFFSHORE SERVICES, INC.

Asset and Goodwill Impairment Assessment In the second quarter of 2009, triggering events occurred which resulted in the Company performing impairment tests on its Downstream segment assets as well as the conventional OSVs in its Upstream Segment. This resulted in the Company recording a non-cash asset impairment charge of $25.8 million, included in depreciation expense, related to ten single- hulled tank barges and six ocean-going tugs, and a $0.9 million non-cash charge, included in amortization expense, for the write-off of remaining goodwill associated with the Company’s Downstream segment. Based on the analysis performed, no impairment existed for any of the Company’s conventional OSVs. The specific triggering events were the Downstream segment operating loss for the quarter ended June 30, 2009, the lack of any material new contracts for the Downstream segment since March 31, 2009, and the lack of any expected change in performance in that segment in the near term. As of June 30, 2009, the Company had stacked all of its conventional OSVs, which it considered to be a triggering event for those specific assets. The impairment assessment compared the net book values of the Company’s Downstream marine assets, as well as Downstream segment goodwill that was booked upon the Company’s formation in June 1997, to their respective fair values. The analysis performed during the second quarter of 2009 included considering recent vessel sales, quoted market prices and past third-party appraisals. Based on recent comparable vessel sales in the second half of 2009 and third party appraisals obtained during the fourth quarter of 2009 in connection with the Company’s amended and extended revolving credit facility in November 2009, no further impairment for the Company’s vessels was deemed necessary as of December 31, 2010 and 2009. No new triggering events have occurred since June 30, 2009. The Company considered whether the curtailed level of drilling activity in the GoM represented an indicator of impairment for any of its asset groups and concluded it did not. Some factors that the Company considered were the anticipated temporary nature of the reduced drilling activity, projected operating results for assets groups, the significant remaining operating useful life, mobility and flexibility of the Company’s vessels. The Company did not record any impairment losses related to its long- lived assets during 2008 or 2010. F-24 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) 15. Segment Information The Company provides marine transportation and logistics services through two business segments. The Company primarily operates new generation OSVs and MPSVs in the U.S. Gulf of Mexico, or GoM, other U.S. coastlines, Latin America and the Middle East and operates a shore-base facility in Port Fourchon, Louisiana through its Upstream segment. The OSVs, MPSVs and the shore-base facility principally support complex exploration and production projects by transporting cargo to offshore drilling rigs and production facilities and provide support for oilfield and non-oilfield specialty services, including military applications. The Downstream segment primarily operates ocean-going tugs and tank barges in the northeastern United States, the GoM, Great Lakes and Puerto Rico. The ocean-going tugs and tank barges provide coastwise transportation of refined and bunker grade petroleum products as well as non-traditional downstream services, such as support of deepwater well testing and other specialty applications for the Company’s upstream customers. The following table shows reportable segment information for the years ended December 31, 2010, 2009, and 2008, reconciled to consolidated totals and prepared on the same basis as the Company’s consolidated financial statements (in thousands).

(2) 16. Employment Agreements The Company has employment agreements with certain members of its executive management team. These agreements include, among other things, contractually stated base level salaries and a structured cash incentive compensation program dependent upon the Company achieving certain targeted financial results. The agreements contain an EBITDA F-26 HORNBECK OFFSHORE SERVICES, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) target, as well as a discretionary component, established by the Compensation Committee of the Company’s Board of Directors, in setting the cash incentive compensation for such executives under this program. In the event such a member of the executive management team is terminated due to certain events as defined in such officer’s agreement, the employee will continue to receive salary, bonus and other payments for the full remaining term of the agreement. The current term of these employment agreements expires on December 31, 2013 and automatically extends each year thereafter on January 1st, for an additional year. 17.
