Any decision rendered by the Accounting Arbitrator pursuant hereto shall include a written statement as to the basis for such decision and shall be final, conclusive and binding on Seller and Buyer and will be enforceable against any of the parties in any court of competent jurisdiction. Seller shall bear one-half and Buyer shall bear one-half of the costs of the Accounting Arbitrator, and Seller and Buyer shall bear its own legal fees and other costs in presenting its case. As to any Imbalances which exist, the parties agree that from and after the Effective Date, any and all benefits, obligations and liabilities associated with Imbalances shall accrue to, and be the responsibility of, Buyer. The Final Settlement Statement shall include an adjustment for any Imbalance differences between those estimates shown on Schedule 3.3 and the actual Imbalances as of the Effective Date. The accuracy of the volumes and prices used herein in the Purchase Price adjustments shall be subject to Purchaser’s audit rights under Section 3.6. Seller shall furnish to Buyer with the Final Settlement Statement reasonably sufficient documentation including operator’s Imbalance Statements, to the extent in Seller's possession, to determine the correct volume and value of each imbalance under the terms of the applicable contract.

3.8 Allocation of Purchase Price / Allocated Values. Buyer and Seller agree that the unadjusted Purchase Price shall be allocated among the Assets as set forth in Schedule 3.8 of this Agreement. The “Allocated Value” for any Asset equals the portion of the unadjusted Purchase Price allocated to such Asset on Schedule 3.8 and such Allocated Value shall be used in calculating adjustments to the Purchase Price as provided herein.

(g) within two (2) Business Days following the execution by Buyer and Seller of this Agreement, Seller will notify the holders of certain overriding royalty interests of Seller’s intent to exercise the ORI Repurchase Option pursuant to Section 1.2(a) of that certain Conveyance of Overriding Royalty Interest dated effective June 29, 2001. In the event that Seller is not successful in repurchasing such overriding royalty interests by the Closing Date, (i) the Purchase Price will be reduced in accordance with Exhibit F at Closing, and Seller and Buyer agree to amend Exhibit B to this Agreement to exclude such overriding royalty interests as an Asset and

(ii) Seller will use commercially reasonable efforts to repurchase such overriding royalty interests within one hundred twenty (120) days after Closing. In the event within one hundred twenty (120) days after Closing Seller is successful in such efforts and upon receipt by Buyer of an executed and acknowledged recordable assignment covering such repurchased overriding royalty interests, Buyer shall pay to Seller consideration in accordance with Exhibit F.

Buyer acknowledges that Seller owns undivided interests in certain of the properties comprising the Assets that it is not the operator thereof, and Buyer agrees that the acts or omissions of the other Working Interests owners (including the operators) who are not Seller or any Affiliates of Seller shall not constitute a breach of the provisions of this Section 7.1, nor shall any action required by a vote of Working Interest owners constitute such a breach so long as Seller has voted its interest in a manner that complies with the provisions of this Section 7.1.

7.2 Bonds, Letters of Credit and Guarantees. Buyer acknowledges that none of the bonds, letters of credit and guarantees, if any, posted by Seller or its Affiliates with Governmental Authorities or Third Parties and relating to the Assets are transferable to Buyer. Except to the extent that Buyer will, as of Closing, be covered by the bonds of the operators of the applicable Assets, then Buyer shall obtain, or cause to be obtained in the name of Buyer, any bonds, supplemental bonds or other securities which may be required of it to own and operate the Assets pursuant to all applicable federal laws, rules and regulations. No other collateral or security will be required or provided.

7.3 Cooperation. If Closing occurs, Buyer and Seller agree to cooperate with each other in connection with the defense and other actions relating to or arising out of the litigation and claims (including insurance claims) relating to the ownership and operation of the Assets and with respect to future audits. Buyer and Seller agrees to make available each other its employees engaged in, or having information about, the ownership and operation of the Assets, for the purposes of providing testimony, depositions, information and other related activities relating to such litigation, claims and audits.

7.4 Plugging, Abandonment, Decommissioning and Other Costs. In addition to its other obligations under this Agreement, if Closing occurs, Buyer shall comply with all Laws, Leases, Applicable Contracts (including all joint and unit operating agreements) and prevailing industry standards relating to (i) the plugging, abandonment and/or replugging of all Xxxxx, including inactive Xxxxx or temporarily abandoned Xxxxx, included in the Assets, (ii) the dismantling or decommissioning and removal of any Personal Property and other property of whatever kind related to or associated with operations and activities conducted by whomever on the Properties or otherwise, pursuant to the Leases or Applicable Contracts and (iii) the clean-up,

restoration and/or remediation of the property covered by the Leases or related to the Assets

(collectively, the “P&A Obligations”).

7.5 Record Retention. Buyer, for a period of seven years following Closing, will (i) retain the Records, (ii) provide Seller, its Affiliates and its and their officers, employees and representatives with access to the Records (to the extent that Seller has not retained the original or a copy) during normal business hours for review and copying at Seller’s expense and upon reasonable notice, and (iii) provide Seller, its Affiliates and its and their officers, employees and representatives with access, during normal business hours, to materials received or produced after Closing relating to any indemnity claim made under Section 13.2 of this Agreement for review and copying at Seller’s expense. If Buyer shall desire to dispose of or transfer any such Records or other materials upon or after the expiration of such seven-year period, Buyer shall, prior to any disposition, give Seller notice and a reasonable opportunity at Seller’s expense to segregate and remove or copy such Records or other materials as Seller may select.

7.6 Governmental Approvals. Notwithstanding anything to the contrary in Section 15.9, Buyer shall promptly seek, and use its best efforts after Closing to obtain, the unconditional approval by the BOEM/BSEE of (i) the Assignments of Record Title in Oil and Gas Lease(s) in the form attached hereto as Exhibit D and (ii) the Assignments of Operating Rights in Oil and Gas Lease(s) in the form attached hereto as Exhibit E. In the event Buyer or its nominated operator is elected successor operator under the operating agreements applicable to any of the Leases, Buyer also obligates itself to ensure that it or the successor operator (1) files all appropriate forms, declarations or bonds with Governmental Authorities as may be required to change the record operator of any Assets where Seller is the designated record operator, (2) makes application to the BOEM/BSEE to qualify as operator with respect to that portion of the Assets it will operate and (3) takes all actions necessary to qualify as an operator under any applicable joint operating agreement (subject to the terms of that operating agreement) and to provide appropriate evidence of financial responsibility as required by the OPA. Buyer shall take any actions reasonably required of it by the BOEM/BSEE or any other regulatory agencies to obtain all requisite regulatory approvals, including but not limited to, the purchase and posting of any and all bonds, supplemental bonds or other securities which may be required of it pursuant to OPA and 30

C.F.R §§ 250.7, 256.58, 256.59, and 256.61 in excess of any existing lease, pipeline or area-wide bond(s). Until the governmental approval with respect to an assignment described in this Section

7.6 is obtained, however, the following shall occur:

(a) Seller shall continue to hold the operating rights and record title to the applicable Assets as nominee for Buyer;

(b) Buyer’s indemnity under Section 13.3 shall include any and all claims, expenses of any kind or character relating to the Assets accruing after the Effective Time including but not limited to any bonding or regulatory costs incurred by Seller;

(c) Seller shall act as Buyer’s nominee with respect to the Assets but shall be authorized to act only upon and in accordance with Buyer’s specific written instructions, and Seller shall have no authority, responsibility or discretion to perform any tasks or functions with respect to the Assets other than those which are purely administrative or ministerial in nature, unless otherwise specifically requested and authorized by Buyer in writing; and

(d) Buyer shall continue to maintain and provide at its cost the insurance coverages as reviewed by Seller under Section 9.5 of this Agreement.

If the BOEM/BSEE does not, within twelve months from the Closing Date, approve all (i) the Assignments of Record Title of the Leases into Buyer and (ii) the Assignments of Oil and Gas Lease Operating Rights, then:

(w) As to those assignments that the BOEM/BSEE has approved, the transaction contemplated by this Agreement will proceed as to those Assets in accordance with the terms and conditions of this Agreement, mutatis mutandis; and

(x) As to those assignments that the BOEM/BSEE has not approved due to a reason other than the BOEM/BSEE’s delay in addressing otherwise valid filings by Buyer, Seller, at its option, may either:

(i) continue to hold the operating rights, title to the Leases and the rights of way as Buyer’s nominee, or,

(ii) upon 30 days’ notice to Buyer, rescind the purchase and sale of the Assets that are the subject of such non-approvals and terminate this Agreement as to those Assets, but only as to those Assets.

(y) The exercise by Seller of the option to rescind as specified in the preceding clause (x)(ii), however, shall be predicated upon Seller’s reasonable determination either that (i) Buyer has failed to comply with the requirements of 30

C.F.R. § 256.64 and not taken any and all actions required by BOEM/BSEE to obtain such approval, or (ii) there had been a material adverse effect on the financial condition of Buyer after Closing.

(z) Upon such termination and rescission, this Agreement shall be null and void as between Buyer and Seller with respect to the non-approved Assets, and (i) Buyer shall return to Seller the assignments and any and all other documents, materials and data previously delivered to Buyer with respect to such Assets; and (ii) Seller shall return to Buyer the Purchase Price allocated to such Assets in Schedule 3.8, without interest, less the proceeds of production net of all expenses, capital expenditures, royalties, and costs of operations (including plugging and abandonment expenses but excluding mortgage interest and any burdens or encumbrances created by Buyer which shall be released prior to this payment) attributable to the Leases and other rights from and after the Effective Time. Seller shall not be liable to Buyer if BOEM/BSEE approvals are not obtained, except as expressly provided in this Section 7.6.

7.7 Special Warranty of Title. If the Closing occurs, then effective as of the Closing Date, Seller warrants Defensible Title to the Assets from and against the lawful claims of third parties arising by, through or under Seller, but not otherwise (such warranty, the “Special Warranty”). This Special Warranty shall, to the fullest extent permitted by applicable Law, be the exclusive right and remedy of Buyer with respect to title to the Assets. Except for the Special Warranty, Buyer, on behalf of itself and its successors, assigns and insurers, releases, remises and forever discharges Seller from any and all claims, demands, damages, losses, costs,

liabilities, interest or causes of action whatsoever, in Law or in equity, known or unknown, which Buyer

might now or subsequently may have, based on, relating to or arising out of, any failure to have Defensible Title or other deficiency in or encumbrance on title to any Asset.

7.8 SEC Sec. 210.3-05.

(d) Requests by Buyer for cooperation, access and documentation pursuant to clauses (a) through (c) of this Section 7.8 shall be given with reasonable specificity and with reasonable advance notice to Seller and Seller’s Representatives so as not to unreasonably interfere with Seller’s or any of Seller’s Representative’s conduct of business.

(e) For a period of three (3) years following the Closing Date, Seller shall retain, or caused to be retained, all books, Records, information and documents in its possession that may be necessary in connection with the preparation and audit of financial statements with respect to the Assets.

(f) Buyer shall reimburse Seller and Seller’s Representatives for their reasonable out-of-pocket costs, including fees of any independent auditor, including

general and administrative expenses, incurred by Seller and Seller’s Representatives in complying with the provisions of this Section 7.8.

Seller shall perform the following marketing functions with respect to the Assets from and after the Closing Date until the earlier of (i) the last day of the calendar month in which falls the date that is ninety (90) days after the Closing Date and (ii) the last day of the calendar month in which falls the date that is five (5) days after the delivery of a notice from Buyer to Seller requesting early termination of such services by Seller: (i) pipeline nominations, (ii) marketing, and (iii) transportation of production. Seller and its shareholders, directors, officers, affiliates, employees, attorneys, contractors and agents shall have no liability for or in connection with any and all claims, demands, suits, causes of action, losses, damages, liabilities, fines, penalties and costs (including attorneys’ fees and costs of litigation) whether known or unknown, asserted or unasserted (including, without limitation, claims under applicable environmental laws) that are brought by or owed to Buyer or any third party arising out of or resulting from the services performed by Seller at the instruction of Buyer pursuant to this Section 7.9. During the marketing transition, Seller shall promptly provide Buyer true and correct records of all receipts, reports and such other documents as are customarily maintained by it in connection with Seller’s performance of the marketing services.

ARTICLE XII

TITLE MATTERS; ENVIONMENTAL MATTERS; CASUALTIES; TRANSFER RESTRICTIONS

12.1 Title Matters.

(a) General Disclaimer of Title Warranties and Representations. Other than the special warranty in the Assignments to be executed pursuant hereto, Seller makes no warranty or representation, express, implied, statutory or otherwise, not even as to a return of the Purchase Price, with respect to Seller’s title to any of the Assets and Buyer hereby acknowledges and agrees that, Buyer’s sole remedy after Closing for any defect of title shall be the special warranty in the Assignments to be executed pursuant hereto.

(b) Title Defects. Following the execution date of this Agreement until 5:00 p.m. Central Time on the expiration date of the Examination Period:

(i) If Buyer discovers any Title Defect affecting any Asset, Buyer shall notify Seller as promptly as possible, but no later than the expiration of the Examination Period of such alleged Title Defect, except as otherwise expressly set forth herein. To be effective, such notice must (A) be in writing, (B) be received by Seller by 5:00 p.m. Central Time on the expiration date of the Examination Period, (C) describe the Title Defect in sufficient, specific detail (including any alleged variance in the Net Revenue Interest), (D) identify the specific Asset or Assets affected by such Title Defect, and (E) include the value of such Title Defect as determined by Buyer. Any matters that may otherwise 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 of this Article XII but not for purposes of the special warranty of title provided for in the Assignments.

(ii) Upon the receipt of such effective notice from Buyer, Seller may (A) attempt to cure such Title Defect at any time prior to the Closing or (B) exclude the affected Asset from the sale and reduce the Purchase Price by the Allocated Value of such affected Asset.

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

(A) If the Title Defect is a lien or encumbrance upon any Asset, the Title Defect Value is the amount necessary to be paid to remove the lien or encumbrance from the affected Asset.

(B) If the Title Defect asserted is that the Net Revenue Interest attributable to any Asset is less than that stated in Exhibit B or the Working Interest attributable to any Asset is greater than that stated in Exhibit B, then the Title Defect Value shall take into account the relative change in the interest from Exhibit B and the appropriate Allocated Value attributed to such Asset.

(C) If the Title Defect represents an obligation, encumbrance, burden or charge upon the affected Asset (including any increase in Working Interest for which there is not a proportionate increase in 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 Asset, the portion of the Asset affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the affected Asset, and the Title Defect Values placed upon the Title Defect by Buyer and Seller.

(D) If a Title Defect is not in effect or does not adversely affect an Asset throughout the entire productive life of such Asset, such fact shall be taken into account in determining the Title Defect Value.

(E) 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.

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

(G) Notwithstanding anything herein to the contrary, in no event shall a Title Defect Value exceed the Allocated Value of the Asset affected thereby.

(i) With respect to each Title Defect that (A) Seller does not cure on or before the Closing and (B) affects an Asset which Seller has elected to include in the sale pursuant to Section 12.2(b)(ii), except as otherwise provided in this Section 12.2(c), the Purchase Price shall be reduced by an amount equal to the Title Defect Value agreed upon in writing by Buyer and Seller.

(ii) If any Title Defect is in the nature of an unobtained consent to assignment or other restriction on assignability, the provisions of Section 12.5 shall apply.

(iii) If on or before Closing the Parties have not agreed upon the validity of any asserted Title Defect or have not agreed on the Title Defect Value attributable

thereto, any Party shall have the right to elect to have the validity of such Title Defect and/or such Title Defect Value determined by an Independent Expert pursuant to Section 12.3. If the validity of any asserted Title Defect, or the Title Defect Value attributable thereto, is not determined before Closing, then the affected Asset shall be excluded from the sale and the Purchase Price shall be reduced by the Allocated Value of such affected Asset

(iv) Notwithstanding anything to the contrary in this Agreement, (A) if the aggregate adjustment to the Purchase Price determined in accordance with this Agreement for Title Defect Values does not exceed one percent (1%) of the Purchase Price prior to any adjustments thereto, then no adjustment of the Purchase Price shall be made therefor, and (B) if the aggregate adjustment to the Purchase Price determined in accordance with this Agreement for Title Defects does exceed one percent (1%) of the Purchase Price prior to any adjustments thereto, then the Purchase Price shall only be adjusted by the amount of such excess.

(v) If the total amount of the Title Defects, Environmental Defects and destruction of the Assets by fire or other casualty or taking of the Assets in condemnation or under right of eminent domain exceeds twenty percent (20%) of the Purchase Price, either Seller or Buyer shall have the option to terminate this Agreement.

(vi) In the event that the Title Defect gives rise to the exclusion of all or part of any Asset from this Agreement as a result of that Title Defect, and there has been a reduction in the Purchase Price, and the Title Defect is cured by Seller after the Closing (provided Seller shall have no obligation to attempt to cure Title Defects), and Seller delivers to Buyer pertinent information reasonably necessary to document the curative action, within 120 days after the Closing Date if not disputed, or immediately after the Independent Expert’s determination under Section 12.3, then Seller shall have the option to put the excluded Asset to Buyer, such put option shall be exercised by Seller delivering written notice to Buyer of Seller’s election to put the excluded Asset to Buyer within 120 days after the Closing Date, and, in exchange for an assignment in the form of Exhibit C, effectuating the transfer of the excluded Asset, Buyer shall pay to Seller an

amount equal to the amount deducted from the Purchase Price (or as agreed or resolved in the event of a dispute), adjusted as provided in Section 3.3, with respect to such Asset. Any dispute regarding matters arising under this Section

12.2(c)(vi) shall be resolved exclusively by arbitration using the procedures specified in Section 12.3.

12.2 Environmental Matters.

(a) Environmental Review.

(i) Buyer shall have the right to conduct or cause a consultant (“Buyer’s Environmental Consultant”) to conduct a standard Phase I environmental review of the Assets and Seller’s Records (as set forth in Section

11.1) prior to the expiration of the Examination Period (“Buyer’s Environmental Review”). The cost and expense of Buyer’s Environmental Review, if any, shall be borne solely by Buyer. The scope of work comprising Buyer’s Environmental Review shall be disclosed to Seller prior to commencement thereof and shall not include any intrusive test or procedure (for example, digging, boring, or sampling of soils). Buyer shall (and shall cause Buyer’s Environmental Consultant to): (A) consult with Seller before conducting any work comprising Buyer’s Environmental Review, (B) perform all such work in a safe and workmanlike manner and so as to not unreasonably interfere with Seller’s operations, and (C) comply with all applicable laws, rules, and regulations. Seller shall have the right to have a representative or representatives accompany Buyer and Buyer’s Environmental Consultant at all times during Buyer’s Environmental Review. The Parties shall execute a “common undertaking” letter regarding the confidentiality for the Environmental Review where appropriate. Buyer hereby agrees to release, defend, indemnify and hold harmless Seller Indemnified Parties from and against all Claims arising from, out of or in connection with, or otherwise relating to, Buyer’s Environmental Review, or, any other access to the Assets by Buyer, REGARDLESS OF THE SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE (BUT NOT ANY SELLER INDEMNITIES’ GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), STRICT LIABILITY, REGULATORY LIABILITY, STATUTORY LIABILITY, BREACH OF CONTRACT, BREACH OF WARRANTY OR OTHER FAULT OR RESPONSIBILITY OF A SELLER PARTY OR ANY OTHER PERSON OR PARTY.

(ii) Unless otherwise required by applicable law, Buyer shall (and shall cause Buyer’s Environmental Consultant to) treat confidentially any matters revealed by Buyer’s Environmental Review and any reports or data generated from such review (the “Environmental Information”), and Buyer shall not (and shall cause Buyer’s Environmental Consultant to not) disclose any Environmental Information to any Governmental Authority or other Third Party without the prior written consent of Seller. Buyer may use the Environmental Information only in connection with the transactions contemplated by this Agreement. If Buyer, Buyer’s Environmental Consultant, or any Third Party to whom Buyer has

provided any Environmental Information become legally compelled to disclose any of the Environmental Information, Buyer shall provide Seller with prompt notice sufficiently prior to any such disclosure so as to allow Seller to file any protective order, or seek any other remedy, as it deems appropriate under the circumstances. If this Agreement is terminated prior to the Closing, Buyer shall deliver the Environmental Information to Seller, which Environmental Information shall become the sole property of Seller. Buyer shall provide copies of the Environmental Information to Seller upon

written request from Seller and with payment of any reasonable out of pocket expenses of Buyer for such copies.

(b) Notice of Environmental Defects.

(i) If Buyer discovers any Environmental Defect affecting the Assets, Buyer shall notify Seller prior to the expiration of the Examination Period of such alleged Environmental Defect. To be effective, such notice must: (A) be in writing; (B) be received by Seller prior to the expiration of the Examination Period; (C) describe the Environmental Defect in sufficient, specific detail, including, without limitation, (1) the written conclusion that an Environmental Defect exists, which conclusion shall be reasonably substantiated by the factual data gathered in Buyer’s Environmental Review, and (2) a separate specific citation of the provisions of Environmental Laws alleged to be violated and the related facts that substantiate such violation; (D) identify the specific Assets affected by such Environmental Defect, including, without limitation, a site plan showing the location of the Environmental Defect; (E) make recommendations from Buyer’s Environmental Consultant to cure the Environmental Defect; and (F) state Buyer’s estimate of the Environmental Defect Value, including the basis for such estimate, for which Buyer would agree to adjust the Purchase Price in order to accept such Environmental Defect if Seller elected Section 12.2(c)(i) as the remedy therefor.

(ii) Any matters that may otherwise constitute Environmental Defects, but of which Seller has not been specifically notified by Buyer in accordance with the foregoing, together with any environmental matter that does not constitute an Environmental Defect, shall be deemed to have been waived by Buyer for the purposes of this Article XII. Upon the receipt of such effective notice from Buyer, Seller may (A) attempt to cure such Environmental Defect at any time prior to the Closing, or, with Buyer’s consent, post-Closing, in a manner that is consistent with the applicable Environmental Laws or (B) exclude the affected Asset from the sale and reduce the Purchase Price by the Allocated Value of such affected Asset.

(i) With respect to each Environmental Defect described in a notice delivered in accordance with Section 12.2(b)(i) that (A) Seller does not cure on or before the Closing and (B) affects an Asset which Seller has not elected to exclude from the sale pursuant to Section 12.2(b)(ii)(B), then the Purchase Price

shall be reduced by the Environmental Defect Value of such Environmental Defect as agreed by the Parties, but in no event with respect to item (A) shall the Purchase Price be reduced by more than the Allocated Value of the affected Asset.

(ii) If Buyer and Seller have not agreed as to the (A) validity of any asserted Environmental Defect, (B) the Environmental Defect Value therefor, or (C) the adequacy of the cure, then on or before three (3) Business Days prior to the Scheduled Closing Date either Party shall have the right to elect to have (1) the validity of the asserted Environmental Defect, (2) the Environmental Defect Value for such Environmental

Defect, or (3) the adequacy of the cure, determined by an Independent Expert pursuant to Section 12.3. If the validity of any such asserted Environmental Defect or the amount of any such Environmental Defect Value is not determined by the Closing, the Asset affected by such disputed Environmental Defect shall be excluded from the Closing and the Purchase Price paid at Closing shall be reduced by the Allocated Value of that Asset. Upon resolution of such dispute, subject to this Section 12.2(c), Buyer shall pay Seller the Allocated Value of the affected Asset less the determined Environmental Defect Value, and Seller shall simultaneously convey the affected Asset to Buyer.

(iii) Notwithstanding anything to the contrary in this Agreement, (A) if the aggregate adjustment to the Purchase Price determined in accordance with this Agreement for Environmental Defect Values does not exceed one percent (1%) of the Purchase Price prior to any adjustments thereto, then no adjustment of the Purchase Price shall be made therefor, and (B) if the aggregate adjustment to the Purchase Price determined in accordance with this Agreement for Environmental Defect Values does exceed one percent (1%) of the Purchase Price prior to any adjustments thereto, then the Purchase Price shall only be adjusted by the amount of such excess.

(iv) If the total amount of the Environmental Defects, Title Defects and destruction of the Assets by fire or other casualty or taking of the Assets in condemnation or under right of eminent domain exceeds twenty percent (20%) of the Purchase Price, either Seller or Buyer shall have the option to terminate this Agreement.

12.3 Disputes Regarding Title Defects and Environmental Defects.

(a) Each Party shall have the right to submit disputes regarding Title Defects, or Environmental Defect to an independent expert appointed in accordance with this Section 12.3 (each, an “Independent Expert”), who shall serve as sole arbitrator. The Independent Expert shall be appointed by mutual agreement of the Parties from among candidates with experience and expertise in the area that is the subject of such dispute, and failing such agreement, such Independent Expert for such dispute shall be selected by the Chief Judge of the United States District Court for the Southern District of Texas.

(b) Disputes to be resolved by an Independent Expert shall be resolved in accordance with mutually agreed procedures and rules and failing such agreement, in accordance with the rules and procedures of the Texas Arbitration Act and the Rules of the American Arbitration Association to the extent such Rules do not conflict with such Texas Arbitration Act or the provisions of this Agreement. The Independent Expert shall be instructed by the Parties to resolve such Dispute as soon as reasonably practicable in light of the circumstances. The decision and award of the Independent Expert shall be binding upon the Parties as an award under the Federal Arbitration Act and final and nonappealable 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.

Seller and Buyer.

(d) Any arbitration hearing held pursuant to Section 12.3 shall be held in

Houston, Texas.

12.4 Casualty or Condemnation Loss.

(a) Notwithstanding anything herein to the contrary, from and after the Effective Time, subject to the Closing, Buyer shall assume all risk of loss with respect to production of Hydrocarbons through normal depletion (including watering out of any well, collapsed casing or sand infiltration of any well) and the depreciation of Personal Property due to ordinary wear and tear, in each case, with respect to the Assets.

(b) If, after the date of this Agreement but prior to the Closing Date, any portion of the Assets is destroyed by fire or other casualty or is taken in condemnation or under right of eminent domain, and the aggregate amount of any such loss or taking, along with the total amount of Environmental Defects and Title Defects exceed twenty percent (20%) of the Purchase Price, either party shall have the right to terminate this Agreement and Buyer shall promptly receive back the Deposit. If the aggregate amount of any such loss or taking along with the total amount of Environmental Defects and Title Defects is twenty percent (20%) or less of the Purchase Price, Buyer shall be required to close. If the loss as a result of such individual casualty or taking exceeds two percent (2%) of the Purchase Price and the parties proceed to Closing, Seller shall elect by written notice to Buyer prior to Closing either (i) to cause the Assets affected by such casualty or taking to be repaired or restored to at least its condition prior to such casualty or taking, at Seller’s sole cost, as promptly as reasonably practicable (which work may extend after the Closing Date) or (ii) to indemnify Buyer through a document reasonably acceptable to Seller and Buyer against any costs or expenses that Buyer reasonably incurs to repair the Assets subject to such casualty or taking, or (iii) Seller, at Closing, shall pay to Buyer all sums paid or payable to Seller by Third Parties by reason of such casualty or taking insofar as with respect to the Assets and shall assign, transfer and set over to Buyer or subrogate Buyer to all of Seller’s right, title and interest (if any) in insurance claims, unpaid awards and other rights against Third Parties (excluding any Liabilities, other than insurance claims, of or against any Seller Indemnified Parties) arising out of

such casualty or taking insofar as with respect to the Assets; provided, however, that in the case of (iii), Seller shall reserve and retain (and Buyer shall assign to Seller) all rights, title, interests and claims against Third Parties for the recovery of Seller’s costs and expenses incurred prior to the Closing Date in pursuing or asserting any such insurance claims or other rights against Third Parties or in defending or asserting rights in such condemnation or eminent domain action with respect to the Assets. In the case of (i) - (ii), Seller shall retain all rights to insurance, condemnation awards and other claims against Third Parties with respect to the casualty or taking except to the extent the parties otherwise agree in writing.

(c) If any action for condemnation or taking under right of eminent domain is pending or threatened with respect to any Asset or portion thereof after the date of this Agreement, but no taking of such Asset or portion thereof occurs prior to the Closing Date, Buyer shall nevertheless be required to close and Seller, at Closing, shall assign, transfer and set over to Buyer or subrogate Buyer to all of Seller’s right, title and interest (if any) in such condemnation or eminent domain action, including any future awards therein, insofar as they are attributable

to the Assets threatened to be taken, except that Seller shall reserve and retain (and Buyer shall assign to Seller) all rights, titles, interests and claims against Third Parties for the recovery of Seller’s costs and expenses incurred prior to the Closing in defending or asserting rights in such action with respect to the Assets.

12.5 Preferential Purchase Rights and Consents to Assign.

(a) The provisions of this Section 12.5 shall apply to preferential rights to purchase set forth on Schedule 4.9 that are validly exercisable as a result of the sale of the Properties contemplated hereby and that enable a Third Party to purchase a Property or any part thereof, as a result of such sale of such Properties (or portion thereof) to Buyer (such rights hereafter referred to as “Preference Rights”). Buyer is purchasing the Properties subject to all Preference Rights.

(b) Seller shall send notices of the transactions contemplated hereby to holders of validly exercisable Preference Rights (“Preference Notices”). The Preference Notices shall be in a form reasonably satisfactory to Buyer, and shall include the Allocated Value of the Property or portion thereof affected by each Preference Right. After receiving a response to a Preference Notice, Seller shall promptly provide a copy of the response to Buyer at the address set forth in this Agreement.

(c) In the event, and only in such event, the holder of a Preference Right elects to validly and properly exercise such Preference Right and to purchase the Property subject thereto upon the Closing, Seller shall convey on substantially the same terms and conditions set forth in the applicable assignment attached to this Agreement (subject to such modifications as deemed reasonably necessary by Buyer to reflect the relevant Preference Right transaction, the price and the additional terms as contemplated by this Agreement) the Property or portion of the Property subject to the Preference Right to the holder of such Preference Right at the Closing; provided, however, that Seller shall have no obligation to convey any Property to a Preference Right holder unless and until the

Closing occurs and provided further that Seller shall: (i) convey to Buyer at Closing all Property subject to Preference Rights for which the time for election to exercise such Preference Right has expired and the Preference Right has not been validly and properly asserted (and the Purchase Price to be paid at Closing by Buyer shall be reduced by the Allocated Value of all Properties regarding which a Preference Right has been validly and properly exercised and all Delayed Closing Properties and no other adjustments related to such Properties and Delayed Closing Properties shall be made to the Purchase Price under this Agreement); and (ii) retain all other Property subject to a Preference Right (“Delayed Closing Properties”), subject to Seller’s obligation to convey such Delayed Closing Properties to Buyer at a delayed Closing date (the “Delayed Closing”), and Buyer shall take all such Delayed Closing Properties (other than Delayed Closing Properties for which the Preference Right has been validly and properly asserted). Notwithstanding the foregoing, all Delayed Closing Properties (other than Delayed Closing Properties for which the Preference Right has been validly and properly asserted) will be conveyed to Buyer at the Delayed Closing, which shall occur within fifteen (15) days after the time that the election to exercise such Preference Rights on all Delayed Closing Properties has expired; provided, however, that if the Delayed Closing has not occurred within one hundred

twenty (120) days after the Closing Date, Buyer shall not be obligated to take assignment of the Delayed Closing Properties. The date of the Delayed Closing shall become the new Closing Date with respect to such Delayed Closing Properties). Prior to the Delayed Closing Seller shall prepare a Preliminary Settlement Statement in accordance with Section 3.5. The Delayed Closing shall occur, to the extent applicable, in accordance with Section 10.3 and, at the Delayed Closing, Buyer shall pay Seller an amount equal to the amount by which the Purchase Price was reduced on account of the holding back of such retained Delayed Closing Properties (as adjusted pursuant to Sections 3.3 and 3.4 through the new Closing Date therefor). The final purchase price adjustments for the Delayed Closing Properties shall be made at the same time as the final purchase price adjustments for all other Assets and pursuant to Section 3.6.

(d) Buyer acknowledges that Seller desires to sell all of the Assets and would not have entered into this Agreement but for Buyer’s agreement to purchase all of the Assets as herein provided. Accordingly, it is expressly understood and agreed that Seller does not desire to sell any Asset that is subject to a Preference Right (collectively the “Preference Right Assets”) unless the sale of all of the Assets is consummated on the Closing Date in accordance with the terms of this Agreement. In furtherance of the foregoing, Seller’s obligation hereunder to sell the Preference Right Assets to Buyer is expressly conditioned upon the consummation on the Closing Date of the sale of all of the Assets in accordance with the terms of this Agreement, either by conveyance to Buyer or conveyance pursuant to an applicable Preference Right; provided that, nothing herein is intended or shall operate to extend or apply any Preference Right to any portion of the Assets which is not otherwise burdened thereby. Time is of the essence with respect to the parties’ agreement to consummate the sale of the Assets on the Closing Date.

(e) Seller shall send to each holder of a right to consent to assignment pertaining to the Assets and the transactions contemplated hereby a notice seeking such

party’s consent to the transaction contemplated hereby. If Seller fails to obtain a consent prior to the Closing and the failure to obtain such consent would cause the assignment of such Asset to Buyer to be void, then Seller shall continue to hold the operating rights or other legal title to such Asset as nominee for Buyer; provided, however, that Buyer shall have no obligation to acquire Seller’s interest in Medusa Spar or the Assets associated with Mississippi Canyon Blocks 538 and 582 until the consents to assignment for the contracts listed under the heading “Medusa” in Schedule 4.4 have been obtained. Seller shall not be obligated to incur any expenses, obligations or other liabilities, or be responsible for any Claims, in Seller’s capacity as nominee and Buyer shall indemnify, defend and hold harmless Seller in relation to such Assets. Seller and Buyer, as between themselves, shall treat and deal with such Assets as if full legal and equitable title to such Assets had passed from Seller to Buyer at Closing. If Seller fails to obtain a consent prior to Closing and such consent does not relate to a material Asset or the failure to obtain such consent would not cause the assignment of such Asset to Buyer to be void, then Buyer shall have no rights or remedies against Seller with respect thereto.

13.4 Express Negligence. The indemnification, release and Assumed Obligations provided for in this Agreement shall be applicable whether or not the liabilities, losses, costs, expenses and damages in question arose or resulted solely or in part from the gross, sole, active, passive, concurrent or comparative negligence, strict liability or other fault or violation of law of or by any Indemnified Party. Buyer and Seller acknowledge that this statement complies with the express negligence rule and is conspicuous.

13.5 Indemnification Procedures. All claims for indemnification under Sections

13.2 and 13.3 shall be asserted and resolved as follows:

(a) Notwithstanding anything to the contrary in this Agreement, the Buyer Indemnified Parties shall not be entitled to indemnification under, and shall not assert any claim for indemnification pursuant to, Section 13.2 until the aggregate amount of such claims exceeds 1% of the Purchase Price (the “Indemnification Threshold”), and then only to the extent the claim exceeds the Indemnification Threshold. In no event will Buyer be entitled to indemnification under Section 13.2 once the aggregate of all claims made under such Section equals 15% of the Purchase Price (the “Indemnification Cap”); provided that Section 13.6, the Indemnification Threshold and/or the Indemnification Cap shall not apply with respect to any claim for indemnification asserted under Sections

13.2(a), or (d) through (j).

(b) For purposes of this Article XIII, the term “Indemnifying Party” when used in connection with particular Liabilities shall mean the party or parties having an obligation to indemnify another party or parties with respect to such Liabilities pursuant to this Article XIII, and the term “Indemnified Party” when used in connection with particular Liabilities shall mean the party or parties having the right to be indemnified with respect to such Liabilities by another party or parties pursuant to this Article XIII.

Indemnified Party shall notify the Indemnifying Party of its claim under this Section

13.5, including the specific details of and specific basis under this Agreement for its

claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a Third Party against the Indemnified Party (a “Claim”), the Indemnified Party shall provide its Claim Notice promptly after the Indemnified Party has actual knowledge of the Claim and shall enclose a copy of all papers (if any) served with respect to the Claim; provided that the failure of any Indemnified Party to give notice of a Claim as provided in this Section 13.5 shall not relieve the Indemnifying Party of its obligations under Sections 13.2 or 13.3 (as applicable) except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Claim or otherwise materially prejudices the Indemnifying Party’s ability to defend against the claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(d) In the case of a claim for indemnification based upon a Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim Notice to notify the Indemnified Party

whether it admits or denies its liability to defend the Indemnified Party against such Claim at the sole cost and expense of the Indemnifying Party. The Indemnified Party is authorized, prior to and during such 30-day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party.

(e) If the Indemnifying Party admits its liability, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Claim. The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate in contesting any Claim which the Indemnifying Party elects to contest. The Indemnified Party may participate in, but not control, any defense or settlement of any Claim controlled by the Indemnifying Party pursuant to this Section 13.5(e). An Indemnifying Party shall not, without the written consent of the Indemnified Party, (i) settle any Claim or consent to the entry of any judgment with respect thereto which does not include an unconditional written release of the Indemnified Party from all liability in respect of such Claim or (ii) settle any Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity).

(f) If the Indemnifying Party does not admit its liability or admits its liability but fails to diligently prosecute or settle the Claim, then the Indemnified Party shall have the right to defend against the Claim at the sole cost and expense of the Indemnifying Party, with counsel of the Indemnified Party’s choosing, subject to the right of the Indemnifying Party to admit its liability and assume the defense of the Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet admitted its liability for a Claim, the Indemnified Party shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for ten days following receipt of such notice to (i) admit in writing its liability for

the Claim and (ii) if liability is so admitted, reject, in its reasonable judgment, the proposed settlement.

(g) In the case of a claim for indemnification not based upon a Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim Notice to (i) cure the Liabilities complained of, (ii) admit its liability for such Liability or (iii) dispute the claim for such Liabilities. If the Indemnifying Party does not notify the Indemnified Party within such 30-day period that it has cured the Liabilities or that it disputes the claim for such Liabilities, the amount of such Liabilities shall conclusively be deemed a liability of the Indemnifying Party hereunder.

13.6 Survival.

(a) Each representation, warranty, covenant and agreement made herein shall terminate and cease to be of further force and effect as of the Closing or such later date after Closing as is expressly stipulated in this Section for the survival thereof; except as to claims for indemnification permitted by this Article XIII as to which a bona fide Claim Notice with respect to such Claim has been delivered to the applicable Indemnifying Party on or prior to such date. If any Asset becomes a retained Asset and the Closing with respect thereto is delayed pursuant to Section 12.3, the parties’ respective representations, warranties, covenants and agreements provided for in this Agreement with respect to such retained Asset shall survive under this Section 13.6 in relation to such delayed Closing rather than the initial Closing under this Agreement. In addition, the definitions set forth in the Definitions section at the beginning of this Agreement or in any other provision of this Agreement which are used in the representations, warranties, covenants and agreements which survive the Closing pursuant to this Section shall survive the Closing to the extent necessary to give operative effect to such surviving representations, warranties, covenants and agreements. It is expressly agreed that:

(i) Sections 4.1, 4.2, 4.3, 4.10, 4.13, 4.14, 5.1, 5.2, 7.2, 7.3, 7.4, 7.6,

12.3, 13.1, 13.2(d), 13.2(e) and Article VI shall survive indefinitely.

(ii) The covenants and agreements of Buyer in Section 7.5 shall survive the Closing for a period of seven years.

(iii) Section 4.16 shall survive until the second anniversary of the

Closing Date.

Date.

(iv) Section 4.4 shall survive until the first anniversary of the Closing

(v) Sections 4.6, 4.7, 4.8, 4.11, and 4.15 shall survive the Closing for a period of six months.

(vi) Sections 4.9 and 4.12 shall terminate on the Closing Date.

(vii) All covenants and obligations of Buyer not identified in the preceding clauses (i) - (vi) shall survive until the first anniversary of the Closing Date.

(viii) The indemnities in Article XIII shall terminate as of the termination date of each respective covenant or agreement that is subject to indemnification, except in each case as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Party on or before such termination date.

13.7 Non-Compensatory Damages. None of the Buyer Indemnified Parties nor Seller Indemnified Parties shall be entitled to recover from Seller or Buyer, or their respective Affiliates, any indirect, consequential, punitive or exemplary damages or damages for lost profits of any kind arising under or in connection with this Agreement or the transactions contemplated hereby, except to the extent any such party suffers such damages (including costs of defense and reasonable attorney’s fees incurred in connection with defending of such damages) to a Third Party, which damages (including costs of defense and reasonable attorney’s fees incurred in connection with defending against such damages) shall not be excluded by this provision as to recovery hereunder. Subject to the preceding sentence, Buyer, on behalf of each of the Buyer Indemnified Parties, and Seller, on behalf of each of Seller Indemnified Parties, waive any right to recover punitive, special, exemplary and consequential damages, including damages for lost profits, arising in connection with or with respect to this Agreement or the transactions contemplated hereby.

13.8 Disclaimer of Application of Anti-Indemnity Statutes. The parties acknowledge and agree that the provisions of any anti-indemnity statute relating to oilfield services and associated activities shall not be applicable to this Agreement and/or the transactions contemplated hereby.

ARTICLE XIV TERMINATION, DEFAULT AND REMEDIES

14.1 Right of Termination. This Agreement and the transactions contemplated herein may be terminated at any time at or prior to Closing:

(a) by Seller, at Seller’s option, if any of the conditions set forth in Article IX have not been satisfied on or before the Scheduled Closing Date, or such other date agreed by Buyer and Seller in accordance with Section 10.1;

(b) by Buyer, at Buyer’s option, if any of the conditions set forth in Article VIII have not been satisfied on or before the Scheduled Closing Date, or such other date agreed by Buyer and Seller in accordance with Section 10.1; or

December 31, 2013 (the “Outside Date”);

provided, however, that no party shall have the right to terminate this Agreement pursuant to clause (a), (b) or (c) above if such party or its Affiliates are at such time in material breach of any provision of this Agreement.

14.2 Effect of Termination. If the obligation to close the transactions contemplated by this Agreement is terminated pursuant to any provision of Section 14.1 hereof, then, except as provided in Section 3.2 and except for the provisions of Sections 1.1, 11.2, 11.3, 13.7 and this Section 14.2 and Article XV (other than Sections 15.2(b), 15.7, 15.8, and 15.9), and any other provision hereof which, by its very nature, must survive such termination so as to carry out the stated intent of Buyer and Seller, this Agreement shall forthwith become of no further force or effort and the parties shall have no liability or obligation hereunder and Seller shall immediately return the Deposit to Buyer, except and to the extent such termination results from the material breach by a party of this Agreement. Upon a material breach of this Agreement by Seller that is not cured by the Closing Date, Buyer, at its sole option and as its sole remedy, may (i) enforce specific performance, or (ii) terminate this Agreement and Seller shall return the Deposit. Upon a material breach of this Agreement by Buyer that is not cured by the Closing Date, Seller, at its sole option and as its sole remedy, may (i) enforce specific performance, or (ii) terminate this Agreement and retain the Deposit.

ARTICLE XV MISCELLANEOUS

15.1 Exhibits and Schedules. All of the Exhibits and Schedules referred to in this Agreement are hereby incorporated into this Agreement by reference and constitute a part of this Agreement. Each party to this Agreement and its counsel has received a complete set of Exhibits and Schedules prior to and as of the execution of this Agreement.

Buyer shall ensure nevertheless that the assignment documents relating to such interests are appropriately filed in the “non-required filing” system of the BOEM/BSEE. Such interests shall be excluded from the scope of Section 7.6 for all purposes.

The other party agrees to cooperate with all reasonable requests of the Electing Party in order to establish and create sufficient documentation to support such federal tax treatment by the Electing Party, provided that the other party shall have no obligation to incur or pay any cost or expense in such connection and the Electing Party shall indemnify and hold the other party harmless from and against all claims and liabilities resulting from such election.
