PURCHASE AND SALE AGREEMENT

This Purchase and Sale Agreement (this “Agreement”) is made and entered into this 21st day of February 2006, by and between Marlin Energy, L.L.C., a Delaware limited liability company (“Seller”), and Energy XXI Gulf Coast, Inc., a Delaware corporation (“Buyer”). Buyer and Seller are collectively referred to herein as the “Parties”, and are sometimes referred to individually as a “Party.”

W I T N E S S E T H:

WHEREAS, Seller is the owner of 100% of the outstanding membership interests in each of Marlin Energy Offshore, L.L.C. (“Marlin Offshore”) and Marlin Texas GP, L.L.C. (“Marlin GP”); and

WHEREAS, Seller is the sole limited partner and Marlin GP is the sole general partner of Marlin Texas, L.P. (the “Partnership” and together with Marlin GP and Marlin Offshore, the “Target Entities” and each, a “Target Entity”); and

WHEREAS, as of the Closing, Marlin Offshore and the Partnership will collectively own the Assets (as hereinafter defined) but only the Assets and no other property of any kind or nature; and

WHEREAS, Seller desires to sell and Buyer desires to purchase all of the membership interests in Marlin Offshore (the “Marlin Offshore Membership Interests”) and Marlin GP (the “Marlin GP Membership Interests” and together with the Marlin Offshore Membership Interests, the “Membership Interests”) and all of the limited partner interest in the Partnership (the “Limited Partner Interest” and together with the Membership Interests, the “Securities”), all upon the terms and conditions hereinafter set forth:

NOW, THEREFORE, in consideration of the mutual benefits derived and to be derived from this Agreement by each Party, Seller and Buyer hereby agree as follows:

ARTICLE I

Purchase and Sale

Section 1.01. Agreement to Sell and Purchase. Subject to and in accordance with the terms and conditions of this Agreement, Seller agrees to sell and Buyer agrees to purchase the Securities. It is hereby expressly acknowledged by the Parties that Buyer has valued the purchase of the Securities as if the Assets (together with the limited partner interest in the Partnership) were the only assets owned by the Target Entities. For this reason, but subject to the remaining provisions of this Section 1.01, the Parties acknowledge that it is their desire that the transaction be structured so that, after the Closing, Buyer is not entitled to receive and the Target Entities shall not hold any property of any kind or nature other than the Assets in connection with the transactions contemplated hereby (with Seller expressly retaining and being entitled to a distribution of all of the assets and properties of the Target Entities other than the Assets in accordance with the terms of this Agreement). Notwithstanding anything to the contrary in this Agreement, except for those Excluded Assets described on Exhibit F or in Sections 1.03(a) through and including 1.03(y), the Parties intend that, after the Closing, the

Target Entities will own those assets and properties that the Target Entities currently own and use primarily in connection with the ownership and/or operation of the Subject Interests and Wells.

Section 1.02. Assets. Subject to Section 1.03, as used herein, the term “Assets” shall mean the following:

(c) all permits, licenses, franchises, consents, approvals and other similar rights and privileges (the “Permits”), in each case to the extent used in connection with the ownership or operation of the Subject Interests and held by any Target Entity;

ARTICLE II

Purchase Price

Section 2.01. Purchase Price. The total consideration for the purchase, sale and assignment of the Securities to Buyer is Buyer’s cash payment to Seller at Closing (“Purchase Price”) of the sum of FOUR HUNDRED TWENTY ONE MILLION FIFTY EIGHT THOUSAND AND SEVEN HUNDRED DOLLARS AND NO/100 ($421,058,700) as adjusted in accordance with the provisions of this Agreement.

Section 2.02. Deposit.

(a) Concurrently with the execution of this Agreement by Buyer and Sellers, Buyer shall deliver a deposit by wire transfer to JPMorganChase Bank, N.A. (“Escrow Agent”) in an amount equal to Five Hundred Thousand and no/100 Dollars ($500,000) (the “Initial Deposit”) to hold in an interest bearing account pursuant to the terms of this Agreement and the Escrow Agreement attached hereto as Exhibit J (the “Escrow Agreement”). On or before the tenth (10th) day following the date hereof, Buyer shall have the right to increase the Initial Deposit by an additional Nine Million Five Hundred Thousand and no/100 Dollars ($9,500,000) (the “Additional Funds”), by delivering such amount by wire transfer to the Escrow Agent. Should Buyer in fact so increase the Initial Deposit within such ten (10) day period by such amount, then the provisions of Section 2.05 hereof shall be disregarded in their entirety and be of no force or effect, the intention of the Parties being that this Agreement be construed as if such Section was not a part hereof. All monies placed with the Escrow Agent pursuant to this Section 2.02 shall accrue interest in accordance with the Escrow Agreement from the date such monies are deposited with the Escrow Agent until the earlier of the Scheduled Closing Date or the termination of this Agreement. Thereafter, if the Deposit is delivered to Seller to hold because Buyer has extended the Closing in accordance with Section 11.02, Seller shall hold such Deposit but such monies shall accrue no interest from the Scheduled Closing Date until the Extended Closing Date. All monies placed with the Escrow Agent pursuant to this Section 2.02 plus any such accrued interest shall be included in the term “Deposit.” All fees payable to the Escrow Agent under the Escrow Agreement shall be borne and paid one-half by Buyer and one-half by Seller.

(b) If the transactions contemplated by this Agreement are consummated on or before the Scheduled Closing Date, the Deposit shall be distributed to Seller by the Escrow Agent as payment of a portion of the Purchase Price (and Seller and Buyer shall deliver joint instructions to the Escrow Agent to accomplish the foregoing), and the amount payable by Buyer at the Closing shall be reduced by the amount of the Deposit. If the Buyer extends the Closing in accordance with Section 11.02 and the transactions contemplated by this Agreement are consummated after the Scheduled Closing Date but on or before the Extended Closing Date, the Deposit shall be retained by Seller as payment of a portion of the Purchase Price, and the amount payable by Buyer at the Closing shall be reduced by the amount of the Deposit. If the transactions contemplated by this Agreement are not consummated, the provisions of Section 12.02 shall apply.

Section 2.03. Allocated Value(s). The Purchase Price is assigned among the Assets, as set forth in Exhibit F (the “Allocated Value(s)”), to be used solely to compute any adjustments to

7

the Purchase Price pursuant to the provisions of Article IV and for no other purpose. Notwithstanding anything contained herein to the contrary, Seller is not acknowledging that the Allocated Value(s) set forth on Exhibit F represent the fair market value of the Assets.

Section 2.04. Section 1031 Like Kind Exchange. Seller shall have the right at any time prior to completion of all the transactions that are to occur at Closing to assign all or a portion of its rights under this Agreement to a “Qualified Intermediary” (as that term is defined in Section 1.1031(k)-1(g)(4)(v) of the Treasury Regulations) in order to accomplish the transaction in a manner that will comply, either in whole or in part, with the requirements of a like-kind exchange pursuant to Section 1031 of the Code. If Seller assigns all or any of its rights under this Agreement for this purpose, Buyer agrees to (a) consent to Seller’s assignment of its rights in this Agreement, which assignment shall be in a form reasonably acceptable to Buyer, and (b) pay the Purchase Price (or a designated portion thereof as specified by Seller) into a qualified escrow or qualified trust account at Closing as directed in writing. Seller and Buyer acknowledge and agree that any assignment of this Agreement (or any rights hereunder) to a Qualified Intermediary shall not release any Party from any of its respective liabilities and obligations hereunder, and that neither Party represents to the other that any particular tax treatment will be given to either as a result thereof.

Section 2.05. Additional Funds Provision. Irrespective of any act or omission on the part of Seller or breach by Seller of any representation, warranty, covenant or agreement of Seller contained herein, in the event that Buyer does not contribute the Additional Funds within the period of time set forth in Section 2.02(a), then the following provisions shall be applicable:

(a) Any and all references to $1,000,000 and $5,000,000 contained in Section 12.02(b) and Section 12.02(d) shall automatically and without any action by any Party be changed to $500,000;

(b) The text of Section 11.03(a)(vi) shall be deleted and the following language shall be substituted in lieu thereof:

(vi) an amount equal to interest at 7% on $421,058,700, for the period from and including January 1, 2006 to but excluding the Closing Date.

(c) During the period from the date hereof up until the Closing or the earlier termination of this Agreement, prior to Buyer discussing any transaction (an “Other Transaction”) with a third party involving (i) the purchase of oil and gas and related assets from a person other than Seller, (ii) a stock or equity interest acquisition other than the Securities, or (iii) a merger or other combination or restructuring transaction with any person other than the Seller or an Affiliate of Buyer, Buyer shall promptly notify Seller. Buyer may negotiate and execute a memorandum of understanding or similar document and negotiate a purchase and sale agreement in connection with any such Other Transaction but may not execute such purchase and sale agreement until such time as the Closing and, should the Closing not occur, for a period of one year after the termination of this Agreement, Buyer shall be prohibited from closing the Other Transaction. Other than with respect to an Other Transaction that Buyer has notified Seller of in accordance with this Section 2.05(c), during the period from the date hereof up until the

8

Closing or the earlier termination of this Agreement, Buyer shall not, directly or indirectly, discuss, seek or consider (i) the purchase of oil and gas and related assets from a person other than Seller, (ii) a stock or equity interest acquisition other than the Securities, or (iii) a merger or other combination or restructuring transaction with any person other than the Seller.

ARTICLE III

Title Matters

Section 4.01. Title Examination Period.

(a) For a period of forty five (45) days following the execution of this Agreement, but in any event, no later than 5:00 p.m. local time in Lafayette, Louisiana on April 7, 2006 (the “Title Examination Period”), Seller shall permit Buyer and/or its representatives to examine, at reasonable times during normal business days and hours and in Seller’s and the Target Entities’ offices, all abstracts of title, title opinions, title files, ownership maps, Lease, Warranty Well and division order files, assignments, operating and accounting records and all Surface Agreements, Permits, Contracts and other agreements pertaining to the Assets or under which the Target Entities will be liable as of the Closing insofar as same may now be in existence and in the possession or control of Seller or any of the Target Entities, subject to such restrictions upon disclosure as may exist under confidentiality or other agreements binding upon Seller, the Target Entities or such data (provided that Seller shall use its reasonable efforts to cause such restrictions to be waived). Notwithstanding anything contained herein to the contrary, in no event shall Buyer have access to or be entitled to review any abstracts of title, title opinions, title files, ownership maps, lease, Well and division order files, assignments, operating and accounting records and all Surface Agreements, Permits, Contracts and other agreements pertaining to the Excluded Assets.

(b) For purposes of this Article IV, the following terms shall have the following meanings:

“PUD Location” means for each PUD Well identified on Exhibit F, the leases identified on Exhibit F as being associated with such PUD Well subject to any depth restriction set forth for such Leases in Exhibit A.

“PUD Well” means a well identified on Exhibit F to be drilled in the future upon a PUD Location which (for the purposes of determining Marketable Title thereto, and any Title Defects or Title Benefits associated therewith, pursuant to this Agreement) shall be treated as if such well had been drilled and completed and was in existence at or prior to the date of this Agreement.

9

“Warranty Well” means a Well or a PUD Well, as the context requires.

Section 4.02. Title Defects. The term “Title Defect” means any encumbrance, encroachment or defect in a Target Entity’s ownership of a Lease and/or Warranty Well that causes the Target Entities not to have Marketable Title to such Lease and/or Warranty Well, provided that an Allocated Value has been assigned to such Lease and/or Warranty Well. The term “Marketable Title” means such ownership by the Target Entities in a Lease and/or Warranty Well that, subject to and except for the Permitted Encumbrances:

(a) entitles the Target Entities to receive not less than the percentage set forth in Exhibit A and/or Exhibit F as the Net Revenue Interest of all Hydrocarbons produced, saved and marketed from such Lease and/or Warranty Well, all without reduction, suspension or termination of such interest throughout the productive life of such Lease and/or Warranty Well, except as specifically set forth in such Exhibit A and/or Exhibit F;

(b) obligates the Target Entities to bear not greater than the percentage set forth in Exhibit A and/or Exhibit F as the Working Interest of the costs and expenses relating to the maintenance, development and operation of such Lease and/or Warranty Well, all without increase throughout the productive life of such Lease and/or Warranty Well, except as specifically set forth in Exhibit A and/or Exhibit F and without a proportionate increase in corresponding Net Revenue Interest; and

(c) is free and clear of all liens and encumbrances.

Section 4.03. Notice of Title Defects.

(a) During the Title Examination Period, if Buyer obtains knowledge of any Title Defect affecting any Lease and/or Warranty Well for which an Allocated Value has been assigned, then Buyer shall notify Seller of such alleged Title Defect on or before the expiration of the Title Examination Period; provided that Buyer will assert any such alleged Title Defect that exceeds the Single Title Defect Threshold as soon as reasonably practicable upon making the determination to assert such Title Defect. To be effective, such notice must (i) be in writing, (ii) be received by Seller prior to the expiration of the Title Examination Period, (iii) describe the Title Defect in reasonable specific detail (including any alleged variance in the Net Revenue Interest or Working Interest), (iv) identify the specific Lease or Leases and/or Warranty Well or Warranty Wells affected by such Title Defect, (v) contain copies of all written data, title opinions and other documents and written information in Buyer’s possession directly relating to the alleged Title Defect and its determination of the Title Defect Value, and (vi) include the Title Defect Value, as reasonably determined by Buyer in good faith. Any matters, including those identified by Buyer during the Title Examination Period, that constitute Title Defects, but of which Seller has not been specifically notified by Buyer in accordance with the foregoing, shall be deemed to have been waived by Buyer for all purposes and shall constitute Permitted Encumbrances. Upon the receipt of such effective notice from Buyer, Seller shall have the option, but not the obligation, to attempt to cure such Title Defect at any time prior to the Closing and shall have the right in its sole discretion to postpone the Scheduled Closing Date up to thirty (30) days beyond the date specified in Section 11.01 to facilitate such cure (and the term “Scheduled Closing Date” shall be amended to be the date so extended by Seller).

10

(b) The value attributable to each Title Defect that is asserted by Buyer in the Title Defect notices (the “Title Defect Value”) shall be determined based upon the criteria set forth below:

(i) If the Title Defect is a lien upon any such Lease and/or Warranty Well, the Title Defect Value is the amount necessary to be paid to remove the lien from the affected Lease and/or Warranty Well.

(ii) If the Title Defect asserted is that the Net Revenue Interest attributable to any Lease and/or Warranty Well is less than the Net Revenue Interest for such Lease and/or Warranty Well set forth in Exhibit A and/or Exhibit F, then the Title Defect Value is the product of the Allocated Value attributed to such Lease, multiplied by a fraction, the numerator of which is the difference between such Net Revenue Interest set forth in Exhibit A and/or Exhibit F and the actual Net Revenue Interest for such Lease and/or Warranty Well, and the denominator of which is such Net Revenue Interest set forth in Exhibit A and/or Exhibit F.

(iii) If the Title Defect represents an obligation, encumbrance, burden or charge upon the affected Lease and/or Warranty Well (including any increase in Working Interest for which there is not a proportionate increase in the corresponding Net Revenue Interest) for which the economic detriment to Buyer is unliquidated, the amount of the Title Defect Value shall be determined by taking into account the Allocated Value of the affected Lease and/or Warranty Well, the portion of the Lease and/or Warranty Well affected by the Title Defect, the legal effect of the Title Defect, the potential discounted economic effect of the Title Defect over the life of the affected Lease and/or Warranty Well, if any, and the Title Defect Values placed upon the Title Defect by Buyer and Seller.

(iv) If a Title Defect does not adversely affect a Lease and/or Warranty Well throughout the entire productive life of such Lease and/or Warranty Well, such fact shall be taken into account in determining the Title Defect Value.

(v) The Title Defect Value of a Title Defect shall be determined without duplication of any costs or losses included in another Title Defect Value hereunder.

(vi) Notwithstanding anything herein to the contrary, in no event shall a Title Defect Value exceed the Allocated Value of the Lease(s) and/or Warranty Well(s) affected thereby.

(vii) Such other factors as are reasonably necessary to make a proper evaluation.

Section 4.04. Remedies for Title Defects.

(a) With respect to each Title Defect that is not cured on or before the Closing, except as otherwise provided in this Section 4.04 and in Section 4.09, the Purchase Price shall be reduced, subject to Section 4.09, by an amount equal to the Title Defect Value agreed upon in writing by Buyer and Seller acting reasonably.

11

(b) If on or before Closing the Parties have not agreed upon the validity of any asserted Title Defect, the Title Defect Value attributable thereto and/or Seller’s cure of same, either Party shall have the right to elect to have the validity of such Title Defect, cure of same and/or such Title Defect Value determined by an Independent Expert pursuant to Section 4.08. If the validity of any asserted Title Defect, cure of same, or the Title Defect Value attributable thereto, is not determined before Closing, the Purchase Price paid at Closing shall be reduced by the Title Defect Value of such disputed Title Defect or Title Defect Value. Upon the final resolution of such dispute, the difference (if any) between the Title Defect Value by which the Purchase Price was reduced and the Title Defect Value determined by the Independent Expert, if any, found to be attributable to any such Title Defect (which is, as a result of the resolution of the dispute, considered to be cured) shall, subject to Section 4.08, be promptly paid to Seller by Buyer, together with interest on such amount at the Interest Rate as accrued from the Closing Date until the date of payment. The term “Interest Rate” shall mean the annual rate of interest published as the “Prime Rate” in the “Money Rates” section of The Wall Street Journal on the execution date hereof (or if not published on such date, such rate as was then last published).

Section 4.05. Permitted Encumbrances. The term “Permitted Encumbrances” shall mean any of the following matters to the extent the same are valid and subsisting and affect the Assets:

(a) any (i) undetermined or inchoate liens or charges constituting or securing the payment of expenses not yet delinquent that were incurred incidental to the maintenance, development, production or operation of the Assets or for the purpose of developing, producing or processing Hydrocarbons therefrom or therein, and (ii) materialman’s, mechanics’, repairman’s, employees’, contractors’, operators’ liens or other similar liens or charges for liquidated amounts not yet delinquent arising in the ordinary course of business;

(b) any liens for taxes and assessments not yet delinquent or, if delinquent, that are being contested in good faith in the ordinary course of business and for which Seller has agreed to pay pursuant to the terms hereof or which have been prorated pursuant to the terms hereof;

(c) the terms, conditions, restrictions, exceptions, reservations, limitations and other matters contained in (including any liens or security interests created by law or reserved in oil and gas leases for royalty, bonus or rental, or created to secure compliance with the terms of) the Contracts and any other agreements, instruments, documents and other matters described or referred to in any Exhibit or Schedule hereto or that create or reserve to the Target Entities their interest in the Assets; provided, that, such matters (i) do not operate to (A) reduce the Net Revenue Interest in any Lease and/or Warranty Well below the Net Revenue Interest reflected in Exhibit A and/or Exhibit F hereto, (B) increase the share of costs and expenses of the maintenance, development or operation of any Lease and/or Warranty Well above the Working Interest reflected in Exhibit A and/or Exhibit F hereto, unless there is a proportionate increase in the corresponding Net Revenue Interest or (C) materially adversely affect or impair the ownership, use or operation of such Assets as they are currently owned, used or operated;

12

(d) any obligations or duties affecting the Assets to any Governmental Authority with respect to any franchise, grant, license or permit, and all applicable laws, rules, regulations and orders of any Governmental Authority;

(f) all royalties, overriding royalties, net profits interests, carried interests, production payments, reversionary interests and other burdens on or deductions from the proceeds of production of Hydrocarbons created or in existence as of the Effective Time, whether recorded or unrecorded, that do not operate to reduce the Net Revenue Interests set forth in Exhibit A and/or Exhibit F, or increase the Working Interests set forth in Exhibit A and/or Exhibit F without a proportionate increase in the corresponding Net Revenue Interests;

(g) all rights to consent by, required notices to, filings with, or other actions by Governmental Authorities in connection with the direct or indirect sale, transfer or conveyance of the Assets that are customarily obtained subsequent to such sale or conveyance;

(h) production sales contracts; division orders; contracts for sale, purchase, exchange, refining or processing of hydrocarbons; unitization and pooling designations, declarations, orders and agreements; operating agreements; agreements of development; area of mutual interest agreements; gas balancing or deferred production agreements; processing agreements; plant agreements; pipeline, gathering and transportation agreements; injection, repressuring and recycling agreements; water or other disposal agreements; seismic or geophysical permits or agreements; and any and all other agreements that are ordinary and customary to the oil, gas and other mineral exploration, development, processing or extraction business or in the business of processing of gas and gas condensate production for the extraction of products therefrom; provided, that, such matters do not operate to (i) reduce the Net Revenue Interest in any Lease and/or Warranty Well below the Net Revenue Interest reflected in Exhibit A and/or Exhibit F, (ii) increase the share of costs and expenses of the maintenance, development or operation of any Lease and/or Warranty Well above the Working Interest reflected in Exhibit A and/or Exhibit F, unless there is a proportionate increase in the corresponding Net Revenue Interest or (iii) materially adversely affect or impair the ownership, use or operation of such Assets as they are currently owned, used or operated;

(k) conventional rights of reassignment arising upon decision to surrender or abandon an interest;

(l) liens related to any debt facility of Seller or its Affiliates to be released at or prior to Closing by Seller without any cost to Buyer or the Target Entities;

M. Huber Corporation and Marlin Energy Offshore, L.L.C.

Section 4.06. Preferential Rights To Purchase and Consents.

(a) After consultation with Buyer, prior to Closing, Seller shall use its reasonable efforts, but without any obligation to incur any material cost or expense in connection therewith, to comply with all preferential right to purchase provisions relative to any Asset and applicable in connection with the transactions contemplated hereby. Prior to the Closing, Seller shall promptly notify Buyer if any preferential purchase rights are exercised, waived or if the requisite period has elapsed without said rights having been exercised. If a third party, who has been offered the right to purchase an interest in any Asset pursuant to a preferential right to purchase, timely elects prior to Closing to purchase such Assets pursuant to such offer, then the Asset or part thereof so affected will be eliminated from the Assets, shall become an Excluded Asset hereunder, and the Purchase Price shall be reduced by the Allocated Value of such Asset. Simultaneously with the Closing, Seller shall cause the Target Entities to transfer such additional Excluded Asset to the third party exercising such preferential right to purchase pursuant to the terms of the agreement creating such preferential purchase right.

(b) In the event the time period in which a preferential right which has been noticed has not expired by Closing and the third party holder of the preferential right has not exercised or waived its right within such period, (i) the affected Asset shall be excluded from the purchase and sale provided for herein, (ii) the affected Asset shall become an Excluded Asset hereunder, (iii) the Purchase Price shall be reduced by the Allocated Value of the affected Asset, and (iv) subject to Section 12.01(f) hereof, Closing shall occur. Prior to the Closing, Seller shall cause the Target Entities to transfer such Excluded Asset to Seller or its designee in accordance with the requirements of Section 1.03 hereof. If, after Closing, the third party does not elect to exercise its right of preferential purchase, waives such right, or is deemed to have waived its right or if, within six (6) months of the Closing, a third party who has elected to exercise its right

14

of preferential purchase fails to close and no dispute therewith is currently existing, then, within ten (10) days after Buyer receives notice from Seller of such waiver or non-election or failure to close, the Parties shall close on the affected Asset and the provisions of this Agreement shall apply to the affected Asset and the closing thereof mutatis mutandis.

Section 4.07. Governmental Authority; Bonds.

(a) For purposes of this Agreement, the term “Governmental Authority” shall mean any federal, state, local, administrative authority, government, department, court, commission, board, bureau, ministry, agency, or other instrumentality of the same or political subdivision exercising or entitled to exercise administrative, executive, judicial, legislative, police, regulatory or taxing authority.

(b) Subject to the Seller’s obligations under Section 8.01(g)(iii), Buyer agrees that at or before Closing it will either (i) (A) have assumed Seller’s guaranty and indemnity obligations with respect to all bonds currently held by the Target Entities and required by the MMS and SMB and any and all other applicable Governmental Authorities to enable the Target Entities to own and/or operate the Assets; (B) have caused the Seller to be released from such guaranty and indemnity obligations with no further liability thereunder or if the holder thereof refuses to so release Seller, post an irrevocable letter of credit from a bank satisfactory to the Seller for the face amount of any bonds (the “Subject Bonds”) where Seller has not been released as of closing from such guaranty or indemnity obligation, or other financial assurance reasonably satisfactory to Seller in order to support Seller’s obligations under such guaranty or indemnity obligation; provided that if Buyer has not caused Seller to be released as guarantor and indemnitor of any of the Subject Bonds by 45 days after Closing, Buyer will pay Seller a fee of seven percent (7%) per annum on the face amount of each Subject Bond where Seller remains obligated; and (C) have posted a replacement letter of credit for the beneficiaries of the letters of credit posted by Seller and set forth on Schedule 6.01(ff) (“Seller’s Letters of Credit”), and have caused Seller’s Letters of Credit to be returned as of Closing or if not so returned post a letter of credit to support Seller’s Letters of Credit, in each case without any cost or liability to Seller, or (ii) have purchased and posted on behalf of the Target Entities any and all letters of credit, bonds, supplemental bonds, sureties, guarantees, other securities or other financial assurances required by the MMS, the SMB and any and all other applicable Governmental Authorities to enable the Target Entities to own and/or operate the Assets. Except for those indemnity obligations, letters of credit, bonds, supplemental bonds, sureties, guarantees, other securities or other financial assurances for which Buyer has provided a back-up letter of credit to fully cover Seller’s obligations thereunder, from and after Closing, Buyer acknowledges that the Seller shall not have any obligation to continue to post, hold or otherwise guarantee or have any indemnification obligation with respect to (or to cause any of the Target Entities to do any of the foregoing) any letters of credit, bonds, supplemental bonds, sureties, guarantees, other securities or other financial assurances required by the MMS, the SMB or any other applicable Governmental Authority pertaining to the Target Entities and the Assets.

The Independent Expert shall be selected by the Parties (acting reasonably and in good faith) within fifteen (15) days following the effective date of said notice and shall be a person who is independent, impartial, and knowledgeable in the subject matter and substantive laws involved. Each Party shall bear its own costs and expenses incurred in connection with any such proceeding, and one-half (1/2) of the costs and expenses of the Independent Expert.

The decision and award of the Independent Expert shall be binding upon the Parties and final and non-appealable to the maximum extent permitted by law, and judgment thereon may be entered in a court of competent jurisdiction and enforced by any Party as a final judgment of such court.

(c) All proceedings under this Section 4.08 shall be conducted in Lafayette, Louisiana or such other mutually agreed location.

Section 4.09. Limitation of Remedies for Title Defects. Notwithstanding anything to the contrary contained in this Agreement, (a) if the Title Defect Value for a given Title Defect, in each case as determined pursuant to Section 4.03(b) or Section 4.08, does not exceed $25,000 (the “Single Title Defect Threshold”), then no adjustment to the Purchase Price shall be made for such Title Defect, (b) if the aggregate Title Defect Values of all Title Defects that were not cured prior to Closing and that exceed the Single Title Defect Threshold does not exceed $500,000, then no adjustment of the Purchase Price shall be made therefore, and (c) if the aggregate Title Defect Values of all Title Defects that were not cured prior to Closing and that exceed the Single Title Defect Threshold exceeds $500,000, then the Purchase Price shall only be adjusted by the amount of such excess above $500,000. All Title Defects asserted by Buyer pursuant to this Article IV shall constitute Permitted Encumbrances, whether or not an adjustment to the Purchase Price is made with respect thereto in accordance with this Article IV. In no event shall any Title Defect Value exceed the Allocated Value for the affected Asset. Subject to the termination provisions of Section 12.01(f), notwithstanding anything to the contrary in this

16

Agreement, the Purchase Price Adjustment provided for in this Article IV shall be Buyer’s sole and exclusive remedy for any Title Defects.

Section 4.10. Remedies for Title Benefits.

(a) If during the Title Examination Period, Buyer discovers any Title Benefit affecting the Leases, it shall promptly notify Seller in writing thereof. If during the Title Examination Period Seller discovers any Title Benefit affecting the Leases, it shall promptly notify Buyer in writing thereof. Seller shall be entitled to an upward adjustment to the Purchase Price with respect to all Title Benefits in an amount (the “Title Benefit Value”) mutually agreed upon by the Parties determined in accordance with the criteria set forth in the definition of the term Title Benefit Value. The term “Title Benefit” shall mean any Target Entity’s Net Revenue Interest in any Lease and/or Warranty Well that is greater than or in addition to the Net Revenue Interest set forth in Exhibit A and/or Exhibit F, or any Target Entity’s Working Interest in any Lease and/or Warranty Well is less than the Working Interest set forth in Exhibit A and/or Exhibit F (without a proportionate decrease in the Net Revenue Interest).

(b) If on or before Closing the Parties have not agreed upon the validity of any asserted Title Benefit and/or the Title Benefit Value attributable thereto, either Party shall have the right to elect to have the validity of such Title Benefit and/or Title Benefit Value determined by an Independent Expert pursuant to Section 4.08. If the validity of any asserted Title Benefit or the Title Benefit Value attributable thereto is not determined before Closing, the Purchase Price paid at Closing shall be increased by the Title Benefit Value of such disputed Title Benefit or Title Benefit Value determined by Buyer, acting reasonably and in good faith, and, upon the final determination of such dispute (i) Seller shall refund to Buyer the amount, if any, by which the amount so paid by Buyer at Closing exceeds such Title Benefit Value or (ii) Buyer shall pay to Seller the amount, if any, by which such Title Benefit Value exceeds the amount so paid by Buyer at Closing, in each case with interest at the Interest Rate as accrued from the Closing Date until the date of payment.

Section 4.11. Limitation of Remedies for Title Benefits. Notwithstanding anything to the contrary contained in this Agreement, (a) if the Title Benefit Value, in each case as determined pursuant to Section 4.04 or as otherwise provided herein, does not exceed $25,000 (the “Single Title Benefit Threshold”), then no adjustment to the Purchase Price shall be made for such Title Benefit, (b) if the aggregate Title Benefit Values of all of the Title Benefits that were discovered prior to the end of the Title Examination Period and that exceed the Single Title Benefit Threshold does not exceed $500,000, then no adjustment of the Purchase Price shall be made therefor, and (c) if the aggregate Title Benefit Values of all Title Benefits that were discovered prior to the end of the Title Examination Period and that exceed the Single Title Benefit Threshold exceeds $500,000, then the Purchase Price shall only be adjusted by the amount of such excess above $500,000.

To the extent Seller has the authority to grant such right (and Seller shall use its reasonable efforts to cause third party operators to grant such right), Buyer shall have the right to conduct environmental reviews related to the environmental and physical condition of the Assets so long as the tests do not unreasonably interfere with the operation of the Assets. Buyer shall keep the results of all such reviews and tests confidential pursuant to the terms of the Confidentiality Agreement and shall provide the results of the same to Seller.

18

HAD AN ADEQUATE OPPORTUNITY TO REVIEW THE WAIVER PROVISION CONTAINED IN THIS SECTION 5.02, INCLUDING THE OPPORTUNITY TO SUBMIT THE SAME TO LEGAL COUNSEL FOR REVIEW AND COMMENT, AND UNDERSTANDS THE RIGHTS BEING WAIVED HEREIN.

Section 5.03. Notice of Environmental Defect. The term “Environmental Laws” shall mean all applicable laws, rules, regulations and orders pertaining to health or safety of the environment. Upon discovery by Buyer of an occurrence(s) or circumstance(s) affecting the ownership or operation of one or more of the Assets which results in such affected Assets not being in compliance with Environmental Laws (“Environmental Defect”), Buyer shall provide Seller with written notice of such Environmental Defect on or before the end of the Environmental Examination Period; provided that if Buyer determines it will assert such Environmental Defect at an earlier date, Buyer will notify Seller as soon as reasonably practicable. The notice shall include:

(a) the Asset affected by the asserted Environmental Defect;

(b) Buyer’s basis for the assertion of such Environmental Defect;

(c) copies of any and all written data, tests results or reports collected or prepared in support of the asserted Environmental Defect; and

(d) Buyer’s good faith estimate of the amount required to remediate the asserted Environmental Defect (the “Environmental Defect Value”).

(e) Subject to Buyer’s remedies for a breach of Seller’s express representations and warranties set forth in Section 6.01(m), any Environmental Defect that is not disclosed to Seller prior to the expiration of the Environmental Examination Period shall conclusively be deemed waived by Buyer for all purposes.

Notwithstanding anything contained in this Agreement to the contrary but subject to Buyer’s remedies for a breach of Seller’s representations and warranties set forth in Section 6.01(m), the Purchase Price adjustment provided in this Section 5.04 shall be Buyer’s sole and exclusive remedy for any and all Environmental Defects related to the Assets. Buyer shall not be entitled to assert any particular Environmental Defect unless the Environmental Defect Value of such Environmental Defect is greater than $25,000 (the “Single Environmental Defect Threshold”). Buyer shall not be entitled to any Purchase Price Adjustment for any Environmental Defect unless and until the aggregate of all Environmental Defect Values of all Environmental Defects that exceed the Single Environmental Defect Threshold exceeds an amount equal to $500,000.

(b) Any downward adjustment to the Purchase Price made in accordance with this Article V shall be limited to the amount by which the sum of all Environmental Defect Values of all Environmental Defects that exceed the Single Environmental Defect Threshold exceeds $500,000. Upon timely delivery of notice of an Environmental Defect, Buyer and Seller

19

shall meet and use their reasonable good faith efforts to agree on the validity of the claim, the Environmental Defect Amount or some other form of mutually acceptable resolution to the Environmental Defect.

(c) With respect to each Environmental Defect that is not cured on or before the Closing, except as otherwise provided in this Section 5.04, the Purchase Price shall be reduced by an amount equal to the Environmental Defect Value agreed upon in writing by Buyer and Seller acting reasonably.

(d) If on or before Closing the Parties have not agreed upon the validity of any asserted Environmental Defect and/or the Environmental Defect Value attributable thereto and/or Seller’s cure of same, either Party shall have the right to elect to have the validity of such Environmental Defect, cure of same and/or such Environmental Defect Value determined by an Independent Expert pursuant to Section 4.08. If the validity of any asserted Environmental Defect, cure of same or the Environmental Defect Value attributable thereto, is not determined before Closing, the Purchase Price paid at Closing shall be reduced by virtue of the Environmental Defect Value of such disputed Environmental Defect or Environmental Defect Value. Upon the final resolution of such dispute the difference (if any) between the Environmental Defect Value by which the Purchase Price was reduced and the Environmental Defect Value determined by the Independent Expert, if any, found to be attributable to any such Environmental Defect (which is, as a result of the resolution of the dispute, considered to be cured) the difference shall, subject to Section 5.04, be promptly paid to Seller by Buyer, together with interest on such amount at the Interest Rate as accrued from the Closing Date until the date of payment.

ARTICLE VIII

Operation of the Assets and Certain Agreements

Section 8.01. Operation of the Assets.

(a) From and after the date of execution of this Agreement, and subject to the provisions of applicable operating and other agreements affecting the Assets, Seller shall (i) use its reasonable efforts during the period prior to the Closing to cause the Target Entities to operate and administer the Assets, and to cause any other operators to operate and administer the Assets, in a manner consistent with past practices, (ii) cause the Target Entities to make payment when due of all costs and expenses attributable to the ownership or operation of the Assets (except when being contested in good faith), and (iii) cause the Target Entities to carry on their respective businesses with respect to the Assets in substantially the same manner as before execution of this Agreement.

(b) After the date hereof until Closing, Seller shall submit to Buyer promptly upon receipt of any AFE or within five (5) business days prior to the giving of any AFE or making any operating or capital expenditure (in each case) for an amount in excess of $250,000.00 net to the Target Entities’ interest. Buyer shall notify Seller in writing at least two (2) business days prior to the expiration of the response period applicable to the AFE or its receipt of Seller’s notice, whichever is earlier, whether it desires for the Target Entities to elect to participate in the relevant operation. If Buyer timely notifies Seller that it desires for the Target Entities to elect to participate in such operation and Seller agrees with such decision, then Seller shall cause the Target Entities to make such election and thereafter upon Closing Buyer shall bear and be responsible or cause the Target Entities to bear and be responsible for all costs and

31

expenses related thereto incurred with respect to the Target Entities’ interest. If Buyer notifies Seller that it does not want the Target Entities to elect to participate in such operation or Buyer is deemed to have elected to not have the Target Entities participate but Seller disagrees with Buyer in the exercise of its reasonable business judgment, then Seller shall cause the Target Entities to make such election and thereafter upon Closing Buyer shall bear and be responsible or cause the Target Entities to bear and be responsible for all costs and expenses related thereto incurred with respect to the Target Entities’ interest. If Buyer timely notifies Seller that it desires for the Target Entities to elect to participate in such operation but Seller in the exercise of its reasonable business judgment disagrees with such decision, then Seller shall cause the Target Entities to make such election but only upon first receiving from Buyer an amount sufficient to cover all costs and expenses related to the Target Entities’ interest. Should Buyer not pay the amount required in the immediately preceding sentence, then Seller shall have no obligation with respect to such AFE. Buyer’s failure to so notify Seller of its desire for the Target Entities to elect to participate in the proposed operation within the time period herein provided shall be deemed an election by Buyer for the Target Entities not to participate.

(c) Buyer acknowledges that the Target Entities own undivided interests in some or all of the Assets, and Buyer agrees that the acts or omissions of the other working interest owners shall not constitute a violation of the provisions of this Article VIII, nor shall any action required by a vote of working interest owners constitute such a violation so long as the Target Entities have voted their interests in a manner that complies with the provisions of this Article VIII. To the extent that a Target Entity is not the operator of any of the Assets, the obligations of Seller in this Article VIII shall be construed to require that Seller use reasonable efforts (without being obligated to incur any expense or institute any cause of action) to cause the operator of such Assets to take such actions or render such performance within the constraints of the applicable operating agreements and other applicable agreements.

(d) From and after the date hereof up to the Closing, Seller shall cause the Target Entities to:

(i) other than in the ordinary course of business consistent with past practices, not enter into any Permit, contract or Lease or terminate or amend in any material respect any Permit, contract or Lease to which any Target Entity is bound or the Assets are subject;

(ii) not purchase any securities of any entity, except short term debt securities of governmental entities and financial institutions, make any investment in any entity or merge of consolidate with any entity;

(iii) not sell, lease or otherwise dispose of any Assets other than (A) the sale of Hydrocarbons produced from the Assets in the ordinary course of business, (B) Assets with an aggregate value of not more than Five Hundred Thousand Dollars ($500,000.00); provided, however, that in no event shall Seller cause any Target Entity to sell, lease or otherwise dispose of any Assets to Seller or any of its Affiliates;

(iv) not purchase, lease or otherwise acquire any property of any kind whatsoever other than (A) in the ordinary course of business consistent with past practices,

32

(B) property with an aggregate value of not more than Two Hundred and Fifty Thousand Dollars ($250,000.00), or (C) in connection with the termination of the Seller’s employee working interest plan as to the Assets at no cost to the Buyer or the Target Entities;

(v) not waive, release or assign any material rights or Claims;

(vi) not fail to use reasonable business efforts to renew any Material Contract or Permit which is part of the Assets or to which any of the Target Entities is bound on substantially the same terms and conditions;

(vii) not implement or adopt any material change in its Tax methods, principles or elections;

(viii) not enter into any employment, services or consulting agreement or hire any person as an employee, consultant or independent contractor;

(ix) not establish, maintain, contribute to or participate in any Benefit Plan not in existence on the date hereof, inclusive of any plan, program, agreement, contract, arrangement or policy, providing for compensation or benefits for employees or contractors;

(x) not make any change in any of its present accounting methods and practices, except as required by U.S. generally accepted accounting principles;

(xi) not declare, set aside or pay any dividends, or make any distributions, in respect of the Securities, or repurchase, redeem or otherwise acquire any of the Securities to the extent the dividends or distributions reflect the Assets; provided, however, that notwithstanding the foregoing, the Seller shall have the absolute right without any liability to Buyer or the Target Entities to take the actions set forth in Sections 1.03 and 8.01(e) provided that such actions are taken in full compliance with such Sections;

(xii) except in the ordinary course of business under existing lines of credit, not create, incur or assume any debt for borrowed money;

(xiii) not make a loan, advance or capital contribution to any person or entity;

(xiv) not amend or modify its organizational documents; and

(xv) not agree to take any action or actions prohibited by any of the foregoing clauses (i) through (xiv).

(e) Buyer agrees and understands that Seller shall have the right to cause the Target Entities to make dividends or distributions of cash and the Excluded Assets directly or indirectly to Seller at any time prior to the Closing. Such right shall not include the right to declare dividends or distributions prior to the Closing that are payable after the Closing. No action taken in accordance with this Section 8.01(e) shall be considered as violation of any other provision of this Agreement. Any action taken pursuant to this Section 8.01(e) shall be taken by

33

the Target Entities without warranty of any kind (express, implied or statutory) and without any liability to Buyer or any Target Entity.

(f) Except to the extent a Target Entity has an obligation to a third party or under applicable law as a result of such breach, in no event shall Buyer’s remedy following Closing for any Seller’s breach of its obligations under Sections 8.01(a), (b), (c) and (d) exceed the Allocated Value of the Subject Interest affected by such breach.

(g) From and after the date hereof up to the Closing, Seller shall:

(i) keep or cause to be kept in full force and effect until Closing all insurance (including operator’s extra expense and casualty coverages) now maintained by Seller (with respect to the Target Entities or the Assets) and/or the Target Entities;

(ii) not encumber or permit any Target Entity to encumber any of the Assets other than for Permitted Encumbrances; and

(iii) maintain or cause to be maintained all of the bonds and other financial assurances set forth on Schedule 6.01(ff).

Section 8.02. Operation of the Target Entities After the Closing. Seller does not warrant or guarantee that the Target Entities will continue to be or will become the operator of the Assets or any portion thereof, as such matter will be controlled by the applicable joint operating agreement(s) and governmental regulations. Subject to the Transition Services Agreement, Seller is hereby released and indemnified by Buyer from all Claims (INCLUDING THOSE RESULTING FROM SELLER’S SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT) accruing with respect to operations of the Assets by the Target Entities after the Closing, except (i) to the extent directly caused by the gross negligence or willful misconduct of Seller, (ii) to the extent any such Claim would relate to a joint interest in the Assets acquired by Seller after the Closing and (iii) to the extent any such Claims constitute a portion of the Retained Obligations. Notwithstanding anything herein to the contrary but subject to Buyer’s remedy for a breach of Seller’s representation and warranty set forth in Section 6.01(r) and the Transition Services Agreement, Seller shall have no liability to Buyer for, and Buyer hereby agrees to release, defend, indemnify and hold harmless Seller from, the incorrect payment of delay rentals, royalties, shut-in royalties or similar payments or for any failure to pay any such payments through mistake or oversight (INCLUDING THOSE RESULTING FROM SELLERS’ SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT) from and after the Effective Time, except to the extent of any amounts included in the upward Purchase Price Adjustment made pursuant to Section 11.03.

Section 8.03. Return of Information. In the event of termination of this Agreement, Buyer shall promptly, and in any event, within ten (10) days of such termination, return or cause to be returned to Seller all documents and other materials obtained from or on behalf of Seller in connection with the transactions contemplated hereby and shall keep confidential any such information, all in accordance with the provisions of the Confidentiality Agreement entered into on December 9, 2005.

34

Section 8.04. No Solicitation. During the period from the date hereof up to the Closing or the earlier termination of this Agreement, Seller shall not, directly or indirectly, seek, solicit or entertain competitive offers to purchase the Assets or the Securities, or otherwise discuss the sale of the Assets or the Securities with any party other than Buyer.

Section 8.05. Intercompany Accounts and Liens. Prior to or on the Closing Date, all intercompany obligations or receivables between any Target Entity and the Seller or any Affiliate of Seller (excluding the Target Entities) shall have been fully satisfied and Seller shall cause the Target Entities and the Assets to be released from any guaranty or lien relating to any indebtedness of Seller or its Affiliates. Except with respect to charges incurred by Seller or its Affiliates on behalf of one of the Target Entities to a third party and which are allocated specifically to one of the Assets, there shall be no Purchase Price Adjustment in connection with the compliance by Seller of its obligations set forth in this Section 8.05.

Section 8.06. Cooperation in Connection with Regulatory Filings. Prior to, and for a period of one year following the Closing, Seller shall, and shall cause its Affiliates and their respective officers, employees and advisors to, provide reasonable cooperation to Buyer, its Affiliates and their representatives in connection with any filings that may be required by the Securities and Exchange Commission (the “SEC”) or otherwise under securities laws applicable to Buyer’s indirect parent, Energy XXI Acquisition Corporation (Bermuda) Limited (“Buyer Parent”), including the filing by Buyer Parent with the SEC of one or more registration statements to register any securities of Buyer Parent under the Securities Act of 1933 (the “Securities Act”) or of any report required to be filed by Buyer Parent under the Securities Exchange Act of 1934 (the “Exchange Act”, and together with the Securities Act, the “Securities Laws”) (collectively, the “Filings”). Further, prior to and for a period of one year following the Closing, Seller agrees to make available to Buyer and its Affiliates and their representatives any and all books, records, information and documents that are attributable to the Assets and Target Entities in Seller’s or its Affiliates’ possession reasonably required by Buyer, its Affiliates and their representatives in order to prepare for Buyer or its Affiliates, if required, in connection with such Filings, financial statements of the Target Entities and the Assets meeting the requirements of Regulation S-X under the Securities Act, along with any documentation attributable to the Assets and Target Entities required to complete any audit associated with such financial statements; provided, however, that notwithstanding anything contained herein to the contrary, in no event shall Buyer have access to nor shall Seller be required to provide Buyer with any books, records, information and documents that relate to either the Excluded Assets (except, if required in connection with the Filings, as it relates to the Excluded Assets that would appear on Target Entities’ balance sheets or otherwise reflected in Target Entities’ financials under U.S. generally accepted accounting principles) or Seller’s consolidated financial statements or any corporate type information even if included in the Target Entities except that Seller will provide such information to Buyer’s auditors to the extent required for Buyer’s auditors to confirm the reasonableness of any allocations made to the Assets; and provided, further, that in no event shall Seller’s reasonable cooperation be deemed to require Seller or its Affiliates to disclose any information contained in any such books, records, information and documents other than as expressly provided herein or as required to enable Buyer to comply with Filings. Without limiting the generality of the foregoing, but subject in all respects to the provisios set forth above, Seller shall, and shall cause its Affiliates to, use their respective commercially reasonable efforts to cooperate with the independent auditors chosen by Buyer Parent (“Buyer’s Auditor”)

35

in connection with any audit by Buyer’s Auditor of any financial statements, balance sheet and statement of cash flows of the Assets and the Target Entities that Buyer Parent or any of its Affiliates requires to comply with the requirements of the Securities Laws with respect to any Filings. Buyer will reimburse Seller, within three (3) business days after demand in writing therefor, for any reasonable out-of-pocket costs incurred by Seller in complying with the provisions of this Section 8.06. For a period of three years following the Closing, Seller shall, and shall cause it Affiliates to, retain all books, records, information and documents in its or its Affiliates’ possession that are necessary to prepare and audit financial statements with respect to the Target Entities and the Assets.

In no event shall either Party be required to indemnify the other Party for any Claim hereunder unless the indemnifying Party receives written notice of the Claim as provided in Section 13.11. The indemnifying Party shall have no liability hereunder with respect to any Claims until the aggregate liability incurred by the indemnified Party for all otherwise indemnified Claims exceeds $500,000 (the “Deductible”) and, thereafter, the indemnifying Party shall be liable hereunder for only those indemnified Claims exceeding the Deductible; provided, that, after the Deductible has been satisfied, the indemnifying Party shall have no liability hereunder with respect to any individual Claim in an amount less than $25,000; and provided further that the foregoing limitations in this sentence shall not apply to any Claims caused by, resulting from or incidental to (a) the Retained Obligations, (b) a breach by a Party of its obligations under Sections 11.05, 11.10(b) or 11.10(c), or (c) any breach of any representation relating to Taxes; and provided further that in calculating the Deductible and the Threshold with respect to any indemnified Claims under Section 13.08(b)(i), all materiality qualifiers (including a Seller Material Adverse Effect) in any Party’s representations and warranties (except for Seller’s representations and warranties under Section 6.01(o)) shall be disregarded. Notwithstanding anything herein to the contrary, the indemnifying Party’s aggregate liability hereunder shall not exceed, and shall be limited to, one hundred percent (100%) of the Purchase Price to Seller (as adjusted hereunder); provided that the foregoing limitations in this sentence shall not apply to any Claims caused by, resulting from or incidental to the Retained Obligations. In addition to the foregoing, the amount of damages for which indemnification is provided under this Article XIII shall be net of any amounts actually recovered by the indemnified Party from third parties other than another indemnified Party (including, without limitation, amounts actually recovered under insurance policies) with respect to the damages. An indemnifying Party shall be subrogated to the rights of an indemnified Party upon the Indemnified Party’s payment in full of the amount of the relevant loss. An insurer who is otherwise obligated to pay a Claim is not relieved of the responsibility with respect to the claim and has no subrogation rights with respect to the claim, in either instance, solely by virtue of the indemnification provisions of this Article XIII. In addition to the foregoing, the amount of damages for which indemnification is provided under this Article XIII shall be net of any amounts of any tax benefit received by the indemnified Party.

Section 13.11. Survival. The representations, warranties, covenants, indemnities and agreements of the Parties set forth herein shall survive the Closing, and the consummation of the transactions contemplated hereby; provided that the representations and warranties, and the covenants and agreements to be performed prior to Closing, (in each case) of Seller shall survive only for a period of one (1) year after the Closing. Notwithstanding anything to the contrary, Buyer shall not be entitled to make, and hereby waives the right to assert, any Claim against Seller for a breach of the representations or warranties, or the covenants and agreements to be performed prior to Closing, (in each case) of Seller, unless Buyer seeks indemnification for such Claim by a written notice received by Seller on or before the date that is one (1) year from the Closing Date.

Section 13.12. Exclusive Remedy. If Closing occurs, except for the Parties’ rights and remedies under the Assignment, the Transition Services Agreement, the Limited Non-Competition Agreement, and the Insurance Assignment, the terms and provisions of this Article XIII and Section 4.07 and Section 8.02 shall be the sole and exclusive remedy of each of the Parties indemnified hereunder with respect to the representations, warranties, covenants and agreements of the Parties set forth in this Agreement and the other documents executed and delivered hereunder.

Section 13.13. Defenses and Counterclaims. Each Party that is required to assume any obligation or liability of the other Party pursuant to this Agreement or that is required to defend, indemnify or hold the other Party harmless hereunder shall, notwithstanding any other provision hereof to the contrary, be entitled to the use and benefit of all defenses (legal and equitable) and counterclaims of such other Party in defense of third party Claims arising out of any such assumption or indemnification.

Section 13.14. Seller Defense of Retained Litigation; Buyer Cooperation. Seller shall be obligated to defend the Target Entities, Buyer and (in each case) the parties related thereto set forth in Section 13.06, at its sole expense, in the Retained Litigation and shall not, without the written consent of Buyer, settle any Claim related to such Retained Litigation or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect Buyer, the Target Entities or the Assets.

Section 15.13. Interpretation. This Agreement shall be deemed and considered for all purposes to have been jointly prepared by the Parties, and shall not be construed against any one Party (nor shall any inference or presumption be made) on the basis of who drafted this Agreement or any particular provision hereof, who supplied the form of Agreement, or any other event of the negotiation, drafting or execution of this Agreement.

In construing this Agreement, the following principles will apply.

(b) If there is any conflict or inconsistency between the provisions of the main body of this Agreement and the provisions of any Appendix, Exhibit or Schedule hereto, the provisions of this Agreement shall take precedence. If there is any conflict between the

60

provisions of the Assignment or other transaction documents attached to this Agreement as an Exhibit and the provisions of the Assignment and other transaction documents actually executed by the parties, the provisions of the executed document shall take precedence.

(c) The Exhibits, Schedules and Appendices referred to herein are hereby incorporated and made a part of this Agreement for all purposes by such reference.

(d) The omission of certain provisions of this Agreement from the Assignment does not constitute a conflict or inconsistency between this Agreement and the Assignment, and will not effect a merger of the omitted provisions.

(f) The Article, Section, Exhibit and Schedules references in this Agreement refer to the Articles, Sections, Exhibits and Schedules of this Agreement.

Notwithstanding the foregoing, Buyer acknowledges that the Target Entities acquired some of the Assets from third parties with some of the Wells having been drilled by such third parties and that Seller acquired Marlin Offshore from a third party, that in connection with such activities Seller and/or the Target Entities conducted such due diligence as at the time they considered reasonable and customary for properties of such nature, and that no current inquiries or investigations of such third parties have been made by, nor are any required of, any of Seller’s or the Target Entities’ personnel in connection with any representation, warranty, covenant or other obligation set out herein that is limited by a knowledge qualifier.
