The Company recorded income from continuing operations for the first quarter of 2015 of $35.9 million, or $0.99 per diluted share. Excluding the impact of the first quarter 2015 gain on sale of assets, income from continuing operations would have been $15.2 million, or $0.42 per diluted share, compared to $11.4 million, or $0.31 per diluted share, for the year-ago quarter; and $18.8 million, or $0.52 per diluted share, for the fourth quarter of 2014. Diluted common shares for the first quarter of 2015 were 36.1 million compared to 36.7 million for the first quarter of 2014 and 36.4 million for the fourth quarter of 2014. EBITDA from continuing operations for the first quarter of 2015 was $94.8 million. Excluding the impact of the first quarter 2015 gain on sale of assets, EBITDA from continuing operations would have been $61.7 million compared to $54.3 million for the first quarter of 2014 and $67.4 million for the fourth quarter of 2014. For additional information regarding EBITDA as a non-GAAP financial measure, please see Note 10 to the accompanying data tables.

Revenues. Revenues were $134.6 million for the first quarter of 2015, a decrease of $2.0 million, or 1.4%, from $136.6 million for the first quarter of 2014; and a decrease of $25.6 million, or 16.0%, from $160.2 million for the fourth quarter of 2014. The year-over-year decrease in revenues was primarily due to soft spot market conditions in the GoM, which led to the Company's decision to stack 18 OSVs on various dates in the fourth quarter of 2014 and thus far in 2015. For the three months ended March 31, 2015, the Company had an average of 9.5 vessels stacked compared to none in the prior-year quarter and 3.3 in the sequential quarter. This year-over-year decrease in revenue was partially offset by $18.1 million in revenue earned from the full or partial-period contribution of 12 vessels that were placed in service since December 2013 under the Company's fifth OSV newbuild program. Operating income was $66.9 million, or 49.7% of revenues, for the first quarter of 2015. Excluding the gain on sale of assets, the Company's operating income for the first quarter of 2015 would have been $33.8 million, or 25.1% of revenues, compared to $25.0 million, or 18.3% of revenues, for the prior-year quarter; and $37.4 million, or 23.3% of revenues, for the fourth quarter of 2014. Average new generation OSV dayrates for the first quarter of 2015 were $26,705 compared to $26,237 for the same period in 2014 and $27,623 for the fourth quarter of 2014. New generation OSV utilization was 64.7% for the first quarter of 2015 compared to 75.3% for the year-ago quarter and 75.7% for the sequential quarter. Excluding stacked vessel days, the Company's new generation OSV effective utilization was 76.6%, 75.3% and 80.0% for the same periods, respectively. The year-over-year decrease in utilization is primarily due to soft market conditions for high-spec OSVs operating in the GoM spot market and the incremental vessels that were stacked in the current-year quarter. The Company's high-spec OSVs incurred 58 days of aggregate downtime for regulatory drydockings and were stacked for an aggregate of 266 days during the first quarter of 2015.

Operating Expenses. Operating expenses were $61.4 million for the first quarter of 2015, a decrease of $7.2 million, or 10.5%, from $68.6 million for the first quarter of 2014; and a decrease of $18.7 million, or 23.3%, from $80.1 million for the fourth quarter of 2014. The year-over-year decrease in operating expenses was driven lower by vessels that the Company idled or stacked since late 2014, which resulted in a substantial reduction in mariner headcount. This decrease was partially offset by $11.5 million of operating costs related to the full or partial-period contribution from vessels added to the Company's fleet since December 2013.

General and Administrative ("G&A"). G&A expenses of $11.9 million for the first quarter of 2015 were 8.8% of revenues compared to $13.7 million, or 10.0% of revenues, for the first quarter of 2014; and $13.9 million, or 8.7% of revenues, for the fourth quarter of 2014. The year-over-year decrease in G&A expenses was primarily attributable to the cancellation of performance-based RSUs that did not achieve their performance vesting criteria, a reduction in bad debt reserves and lower shoreside compensation.

Depreciation and Amortization. Depreciation and amortization expense was $27.5 million for the first quarter of 2015, or $1.9 million lower than the prior-year quarter and $2.1 million lower than the sequential quarter. Depreciation increased by $3.8 million primarily due to the contribution of nine vessels that were placed in-service on various dates since March 2014. The depreciation increase was more than offset by a decrease in amortization expense of $5.7 million, which was largely due to $4.3 million of incremental amortization recorded for the accelerated regulatory drydocking of vessels during the year-ago period. Depreciation and amortization expense is expected to continue to increase from current levels as the vessels under the Company's current newbuild program are placed in-service and when any newly constructed vessels undergo their initial 30-month and 60-month recertifications.

Gain on Sale of Assets. Included in first quarter 2015 results from continuing operations was a $33.1 million ($20.7 million after tax and $0.57 per diluted share) gain on the sale of three 250EDF class OSVs to the U.S. Navy, which closed on February 27, 2015.

Interest Expense. Interest expense was $10.3 million during the first quarter of 2015, or $3.0 million higher than the prior-year quarter. The increase was primarily due to the Company capitalizing a lower percentage of interest compared to the prior-year period. The Company recorded $5.8 million of capitalized construction period interest, or roughly 36% of its total interest costs, for the first quarter of 2015 compared to having capitalized $8.7 million, or roughly 55% of its total interest costs, for the year-ago quarter.

Vessel Sales to U.S. Navy. As previously announced, the Company has recently closed the sale of three 250EDF class OSVs previously chartered to the U.S. Navy. The vessel purchase agreement includes an option for the acquisition of a fourth vessel currently under charter to the U.S. Navy, the HOS Black Powder, that, if exercised as anticipated, would bring the aggregate sale amount to $152.0 million, which is expected to result in an aggregate gain on sale of assets for the four vessels of approximately $44.1 million ($27.6 million after-tax or $0.76 per diluted share). In addition to these vessel sales, the Company separately entered into an operations and maintenance ("O&M") contract for the three vessels sold, which contains an initial term and annual renewal options spanning a 10-year operating period including annual dayrate escalations. Associated with the O&M contract, the Company was also awarded a time charter for the HOS Black Powder that will remain in effect until the anticipated sale of the vessel pursuant to the U.S. Navy purchase option is completed. At such time, the HOS Black Powder will operate under the same terms and conditions as the current O&M contract for the other three vessels. While the U.S. Navy purchase option for the fourth vessel is valid through September 30, 2016, the Company expects to complete the sale of HOS Black Powder by the end of the third quarter of 2015, subject to government funding.

Common Stock Repurchase. On October 28, 2014, the Company's Board of Directors authorized the Company to repurchase up to $150.0 million in shares of its common stock. As of December 31, 2014, the Company had repurchased and retired 891,396 shares at an average price of $28.05 per share. Since December 31, 2014, no additional shares have been repurchased.

Future Outlook

Based on the key assumptions outlined below and in the attached data tables, the following statements reflect management's current expectations regarding future operating results from continuing operations and certain events. These statements are forward-looking and actual results may differ materially given the volatility inherent in the Company's industry. Other than as expressly stated, these statements do not include the potential impact of any significant further decline in commodity prices for oil and natural gas; any additional future long-term contract repositioning voyages; unexpected vessel repairs or shipyard delays; or future capital transactions, such as vessel acquisitions or divestitures, business combinations, additional stock buy-backs, financings or the unannounced expansion of existing newbuild programs that may be commenced after the date of this disclosure. Additional cautionary information concerning forward-looking statements can be found on page 9 of this news release.

Forward Guidance

The Company's forward guidance for selected operating and financial data, outlined below and in the attached data tables, reflects the current state of depressed commodity prices and planned decreases in the capital spending budgets of its customers in recent months.

Vessel Counts. As of March 31, 2015, excluding one inactive non-core conventional OSV, the Company's fleet consisted of 60 new generation OSVs and five MPSVs. The forecasted vessel counts presented in this press release reflect (i) the anticipated fiscal 2015 and 2016 OSV and MPSV newbuild deliveries discussed below; (ii) the OSV-to-MPSV conversion of one 300 class HOSMAX vessel that was completed on April 6, 2015; and, for purposes of this guidance, (iii) the assumed sale of the fourth and final vessel to the U.S. Navy on September 30, 2015. With an average of 15.4 new generation OSVs projected to be stacked during 2015, the Company's active fleet for 2015 is expected to be comprised of an average of 45.5 new generation OSVs and 5.9 MPSVs. For 2015, these active new generation OSVs are comprised of an average of 21.6 "term" vessels that are currently operating under long-term charters and an average of 23.9 "spot" vessels that are currently idle, operating under short-term charters or set to roll off of long-term charters by the end of 2015. With an assumed average of 18.0 new generation OSVs projected to be stacked during 2016, the Company's active fleet for 2016 is expected to be comprised of an average of 44.0 new generation OSVs and 8.8 MPSVs. For 2016, these active new generation OSVs are comprised of an average of 3.9 "term" vessels that are currently operating under long-term charters and an average of 40.1 "spot" vessels that are currently idle, operating under short-term charters or set to roll off of long-term charters by the end of 2016.

Contract Coverage.The Company's forward contract coverage for its current and projected fleet of new generation OSVs (including stacked vessels) for the remainder of fiscal 2015 and 2016 is currently 36% and 7%, respectively. The Company's forward contract coverage for its current and projected fleet of MPSVs for the remainder of fiscal 2015 and 2016 is currently 29% and 0%, respectively. These contract backlog percentages are based on available vessel-days for the guidance periods, not estimated revenue.

Effective Dayrates. Effective, or utilization-adjusted, new generation OSV dayrates for the Company's projected average of 21.6 active "term" OSVs are expected to be in the $24,000 to $26,000 range for the full-year 2015. This range does not reflect the incremental impact of any revenue expected to be derived in the remainder of fiscal 2015 from the Company's "spot" OSVs. The Company does not provide annual guidance regarding the effective dayrates anticipated for its "spot" new generation OSVs or for any of its MPSVs due to the wide range of potential outcomes of its current domestic and international bidding activity for such vessels.

Operating Expenses.Aggregate cash operating expenses are projected to be in the range of $60.0 million to $65.0 million for the second quarter of 2015, and $253.0 million to $268.0 million for the full-year 2015. Not included in these costs is the expected lost revenue related to vessels during approximately 276 days of aggregate commercial-related downtime. Please refer to the attached data table on page 12 of this press release for a summary, by period and by vessel type, of historical and projected data for commercial-related downtime (in days) for each of the quarterly and/or annual periods presented for the fiscal years 2014, 2015 and 2016. Included in the cash opex guidance range above are the anticipated results of several cost containment measures recently initiated by the Company due to prevailing market conditions, including, among other actions, the stacking of 18 new generation OSVs on various dates since October 1, 2014, as well as company-wide headcount reductions and across-the-board pay-cuts for shore-side personnel. The Company may choose to stack additional vessels as market conditions warrant. The cash operating expense estimate above is exclusive of any additional repositioning expenses the Company may incur in connection with the potential relocation of more of its current spot vessels into international markets or back to the GoM from international markets, and any customer-required cost-of-sales related to future contract fixtures that are typically recovered through higher dayrates.

G&A Expenses.G&A expenses are expected to be in the approximate range of $13.0 million to $14.0 million for the second quarter of 2015, and $50.0 million to $55.0 million for the full-year 2015. For future periods, the Company expects to remain within its historical range of G&A-to-revenue margins, as well as those of its domestic public OSV peer group.

Other Financial Data.Projected quarterly depreciation, amortization, net interest expense, cash income taxes, cash interest expense and weighted-average diluted shares outstanding for the second quarter of 2015 are $20.8 million, $7.0 million, $10.4 million, $0.6 million, $11.3 million and 36.2 million, respectively. Guidance for depreciation, amortization, net interest expense, cash income taxes and cash interest expense for the full fiscal years 2015 and 2016 is provided on page 13 of this press release. The Company's annual effective tax rate is expected to be in the range of 37.0% to 38.0% for fiscal years 2015 and 2016.

The Company is monitoring production deficiencies experienced at two of the shipyards and employing all tools contractually available to improve progress and to ensure all possible efforts are made to meet the requirements of the contract. Production at the other yard remains on-time or ahead of schedule. The Company completed the conversion of one of its newbuild HOSMAX 300 class OSVs, the HOS Riverbend, that was previously placed in service under its ongoing newbuild program into a HOSMAX 300 class MPSV. This vessel was re-delivered into the active fleet as a new U.S.-flagged, Jones Act-qualified MPSV in April 2015 and will be included in the Company's MPSV fleet counts and operating statistics beginning in the second quarter of 2015. Based on the updated schedule above of projected vessel in-service dates and the recent 300 class OSV-to-MPSV conversion, the Company now expects to own 62 new generation OSVs as of December 31, 2015. These vessel additions result in a projected average new generation OSV fleet complement of 61.3 and 62.0 vessels for the fiscal years 2015 and 2016, of which 15.8 and 18.0 vessels are projected to be stacked, respectively. Based on the foregoing, the Company now expects to own and operate seven and 10 MPSVs as of December 31, 2015, and 2016, respectively. These vessel additions result in a projected average MPSV fleet complement of 5.9, 8.8 and 10.0 vessels for the fiscal years 2015, 2016 and 2017, respectively. The aggregate cost of the Company's fifth OSV newbuild program, excluding construction period interest, is expected to be approximately $1,265.0 million, of which $188.2 million and $44.4 million are expected to be incurred in fiscal years 2015 and 2016, respectively. From the inception of this program through March 31, 2015, the Company has incurred $1,080.2 million, or 85.4%, of total expected project costs, including $47.8 million that was spent during the first quarter of 2015. The Company expects to incur newbuild project costs of $79.0 million during the second quarter of 2015.

Update on Maintenance Capital Expenditures. Please refer to the attached data table on page 12 of this press release for a summary, by period and by vessel type, of historical and projected data for drydock downtime (in days) and maintenance capital expenditures for each of the quarterly and/or annual periods presented for the fiscal years 2014, 2015 and 2016. Maintenance capital expenditures, which are recurring in nature, primarily include regulatory drydocking charges incurred for the recertification of vessels and other vessel capital improvements that extend or maintain a vessel's economic useful life. The Company expects that its maintenance capital expenditures for its Upstream fleet of vessels will be approximately $19.3 million and $22.9 million for the full fiscal years 2015 and 2016, respectively.

Update on Other Capital Expenditures. Please refer to the attached data tables on page 12 of this press release for a summary, by period, of historical and projected data for other capital expenditures, for each of the quarterly and/or annual periods presented for the fiscal years 2014, 2015 and 2016. Other capital expenditures, which are generally non-recurring, are comprised of the following: (i) commercial-related vessel improvements, such as the addition of cranes, ROVs, helidecks, living quarters and other specialized vessel equipment, or the modification of vessel capacities or capabilities, such as DP upgrades and mid-body extensions, which costs are typically included in and offset, in whole or in part, by higher dayrates charged to customers; and (ii) non-vessel related capital expenditures, including costs related to the Company's shore-based facilities, leasehold improvements and other corporate expenditures, such as information technology or office furniture and equipment. The Company expects miscellaneous incremental commercial-related vessel improvements and non-vessel capital expenditures to be approximately $62.5 million and $12.0 million, respectively, for the full fiscal years 2015 and 2016, respectively.

Liquidity Outlook

As of March 31, 2015, the Company had a cash balance of $279.5 million and an undrawn $300.0 million revolving credit facility. The Company also expects to receive an additional $38.0 million in cash proceeds from the anticipated sale of the fourth 250EDF class OSV to the U.S. Navy during the third quarter of 2015. Together with cash on-hand, the Company expects to generate sufficient cash flow from operations to cover all of its growth capital expenditures for the remaining eight HOSMAX vessels under construction, commercial-related capital expenditures, and all of its annually recurring cash debt service, maintenance capital expenditures and cash income taxes through the completion of the newbuild program, as well as discretionary share repurchases from time to time, without ever having to use its currently undrawn revolving credit facility. The Company has three tranches of funded unsecured debt outstanding that mature in fiscal 2019, 2020 and 2021, respectively. On February 6, 2015, the Company amended and extended the maturity of its existing revolving credit facility to February 2020, provided that, if the 2019 convertible senior notes remain outstanding on March 1, 2019, the Company is required to maintain a specified minimum liquidity level until after the redemption or refinancing of the convertible senior notes, which mature on September 1, 2019.

The Company's actual future results might differ from the forward-looking statements made in this Press Release for a variety of reasons, including significant and sustained or additional declines in oil and natural gas prices; a sustained weakening of demand for the Company's services; unplanned customer suspensions, cancellations, rate reductions or non-renewals of vessel charters or failures to finalize commitments to charter vessels; further reductions in capital spending budgets by customers; the inability to accurately predict vessel utilization levels and dayrates; fewer than anticipated deepwater and ultra-deepwater drilling units operating in the GoM or other regions where the Company operates; the effect of inconsistency by the United States government in the pace of issuing drilling permits and plan approvals in the GoM or other drilling regions; the Company's inability to successfully complete the remainder of its current vessel newbuild program on-time and on-budget, which involves the construction and integration of highly complex vessels and systems; the inability to successfully market the vessels that the Company owns, is constructing or might acquire; the inability of the Company to complete a sale to the U.S. Navy of one additional vessel or the government's cancellation or non-renewal of the operations and maintenance contracts for vessels; an oil spill or other significant event in the United States or another offshore drilling region that could have a broad impact on deepwater and other offshore energy exploration and production activities, such as the suspension of activities or significant regulatory responses; 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; environmental litigation that impacts customer plans or projects; disputes with customers; bureaucratic, administrative or operating barriers that delay vessels chartered in foreign markets from going on-hire or result in contractual penalties or deductions imposed by foreign customers; industry risks; the impact stemming from the reduction of Petrobras' announced plans for or administrative barriers to exploration and production activities in Brazil; less than expected growth in Mexican offshore activities; unanticipated difficulty in effectively competing in or operating in international markets; less than anticipated subsea infrastructure and field development demand in the GoM and other markets; the level of fleet additions by the Company and its competitors that could result in over capacity in the markets in which the Company competes; economic and political risks; weather-related risks; the shortage of or the inability to attract and retain qualified personnel, as needed, including vessel personnel for active and newly constructed vessels; regulatory risks; the repeal or administrative weakening of the Jones Act or changes in the interpretation of the Jones Act; drydocking delays and cost overruns and related risks; vessel accidents, pollution incidents, or other events resulting in lost revenue, fines, penalties or other expenses that are unrecoverable from insurance policies or other third parties; unexpected litigation and insurance expenses; or 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 failure by individual banks to provide funding under the Company's credit agreement, if required. Further, the Company can give no assurance regarding when and to what extent it will affect share repurchases. 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 the Company's most recent 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.

Regulation G Reconciliation

This Press Release also contains references to the non-GAAP financial measures of earnings, or net income, before interest, income taxes, depreciation and amortization, or EBITDA, and Adjusted EBITDA. The Company views EBITDA and Adjusted EBITDA primarily as liquidity measures and, therefore, believes that the GAAP financial measure most directly comparable to such measure is cash flows provided by operating activities. Reconciliations of EBITDA and Adjusted EBITDA to cash flows provided by operating activities are provided in the table below. Management's opinion regarding the usefulness of EBITDA to investors and a description of the ways in which management uses such measure can be found in the Company's most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission, as well as in Note 10 to the attached data tables.

    2                For the three months ended March 31, 2015 and
                     December 31, 2014 the Company had 337 and 140
                     anti-dilutive stock options, respectively. For
                     the three months ended March 31, 2014, the
                     Company had no anti-dilutive stock options.  As
                     of March 31, 2015, December 31, 2014, and March
                     31, 2014, the 1.500% convertible senior notes
                     were not dilutive, as the average price of the
                     Company's stock was less than the effective
                     conversion price of $68.53 for such notes.


    3                The Company owned 60 new generation OSVs as of
                     March 31, 2015.  Excluded from this data is one
                     stacked conventional OSV that the Company
                     considers to be a non-core asset.  Also
                     excluded from this data are five MPSVs owned and
                     operated by the Company.


    4                In response to weak market conditions, the
                     Company elected to stack certain of its new
                     generation OSVs on various dates during the
                     fourth quarter of 2014 and thus far in 2015.
                     Active new generation OSVs represent vessels
                     that are immediately available for service
                     during each respective period.


    5                Average utilization rates are average rates based
                     on a 365-day year.  Vessels are considered
                     utilized when they are generating revenues.


    6                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.


    7                Average new generation OSV 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 revenues.


    8                Effective dayrate represents the average dayrate
                     multiplied by the utilization rate for the
                     respective period.


    9                Represents revenues from shore-based operations,
                     vessel-management services, including from the
                     O&M contract, and ancillary equipment rentals,
                     including from ROVs.


    10              Non-GAAP Financial Measure


                    The Company discloses and discusses EBITDA as a
                     non-GAAP financial measure in its public
                     releases, including quarterly earnings releases,
                     investor conference calls and other filings with
                     the Securities and Exchange Commission.  The
                     Company defines EBITDA as earnings (net income)
                     before interest, income taxes, depreciation and
                     amortization.  The Company's measure of EBITDA
                     may not be comparable to similarly titled
                     measures presented by other companies.  Other
                     companies may calculate EBITDA differently than
                     the Company, which may limit its usefulness as a
                     comparative measure.


                    The Company views EBITDA primarily as a liquidity
                     measure and, as such, believes that the GAAP
                     financial measure most directly comparable to it
                     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 the Company's financial statements as a
                     supplemental financial measure that, when viewed
                     with GAAP results and the accompanying
                     reconciliations, the Company believes provides
                     additional information that is useful to gain an
                     understanding of the factors and trends
                     affecting its ability to service debt, pay
                     deferred taxes and fund drydocking charges and
                     other maintenance capital expenditures.  The
                     Company also believes the disclosure of EBITDA
                     helps investors meaningfully evaluate and
                     compare its 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 the Company's executive officers and other
                     shore-based employees; (iii) to compare to the
                     EBITDA of other companies when evaluating
                     potential acquisitions; and (iv) to assess the
                     Company's ability to service existing fixed
                     charges and incur additional indebtedness.


                    In addition, the Company also makes certain
                     adjustments, as applicable, to EBITDA for losses
                     on early extinguishment of debt, stock-based
                     compensation expense and interest income, or
                     Adjusted EBITDA, to internally evaluate its
                     performance based on the computation of ratios
                     used in certain financial covenants of its
                     credit agreements with various lenders.  The
                     Company believes that these ratios can be
                     material components of financial covenants and,
                     when applicable, failure to comply with such
                     covenants could result in the acceleration of
                     indebtedness or the imposition of restrictions
                     on the Company's financial flexibility.


                     Set forth below are the material limitations
                     associated with using EBITDA as a non-GAAP
                     financial measure compared to cash flows
                     provided by operating activities.


                    EBITDA does not reflect the future capital
                      expenditure requirements that may be necessary
                      to replace the Company's existing vessels as a
                      result of normal wear and tear, 
    EBITDA does not
                      reflect the interest, future principal payments
                      and other financing-related charges necessary
                      to service the debt that the Company has
                      incurred in acquiring and constructing its
                      vessels, 
    EBITDA does not reflect the deferred
                      income taxes that the Company will eventually
                      have to pay once it is no longer in an overall
                      tax net operating loss position, as applicable,
                      and 
    EBITDA does not reflect changes in the
                      Company's 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 the Company's GAAP results.


    11               Commercial-related Downtime results from
                     commercial-related vessel improvements, such as
                     the addition of cranes, ROVs, helidecks, living
                     quarters and other specialized vessel equipment;
                     the modification of vessel capacities or
                     capabilities, such as DP upgrades and mid-body
                     extensions, which costs are typically included
                     in and offset, in whole or in part, by higher
                     dayrates charged to customers; and the
                     speculative relocation of vessels from one
                     geographic market to another.


    12               The capital expenditure amounts included in this
                     table are cash outlays before the allocation of
                     construction period interest, as applicable.


    13               As of April 29, 2015, the Company's active fleet
                     of 26 new generation OSVs that were committed to
                     "term" contracts (time charters of one year or
                     longer in duration at inception) was comprised
                     of the following fleet mix: five 200 class OSVs,
                     fourteen 240 class OSVs and seven 300 class
                     OSVs.


    14               As of April 29, 2015, the Company's active fleet
                     of 15 new generation OSVs that were available
                     for "spot" contracts (time charters of less than
                     one year in duration at inception) or additional
                     "term" contracts was comprised of the following
                     fleet mix: three 240 class OSVs, four 265 class
                     OSVs and eight 300 class OSVs.


    15               As of April 29, 2015, the Company's inactive
                     fleet of 18 new generation OSVs that were
                     "stacked" was comprised of the following: seven
                     200 class OSVs and eleven 240 class OSVs.


    16               The "low" and "high" ends of the guidance ranges
                     set forth in this table are not intended to
                     cover unexpected variations from currently
                     anticipated market conditions.  These ranges
                     provide only a reasonable deviation from the
                     conditions that are expected to occur.

                     Warrants related to the Company's 1.500%
                     convertible senior notes become dilutive when
                     the average price of the Company's stock exceeds
