(a) Promptly after the Execution Date, but in no event later than ten (10) days after the Execution Date, each Party shall prepare and send (i) notices (each a “Consent Request Notice”), to the holders of any Consents set forth on Schedule 5.13 or Schedule 6.13, as applicable, in compliance with the terms of such consents and requesting consents to the applicable Conveyance and, to the extent applicable, an express waiver of any provision that would require the assignment of the applicable Asset subject to such Consent to be delayed until after the Closing Date, and (ii) notices (each a “Preferential Right Notice”), to the holders of any Preferential Rights set forth on Schedule 5.13 or Schedule 6.13, as applicable, in compliance with the terms of such rights and requesting waivers of such rights. With respect to each Consent (other than a Customary Post-Closing Consent) or Preferential Right that is not set forth on Schedule 5.13 or Schedule 6.13, as applicable, but is discovered by a Party prior to Closing, as soon as reasonably practicable after discovery of any such Preferential Right or Consent, such Party shall prepare and send (A) a Consent Request Notice to the holders of any such Consents in compliance with the terms of such consents and requesting consents to the applicable Conveyance and, to the extent applicable, an express waiver of any provision that would require the assignment of the applicable Asset subject to such Consent to be delayed until after the Closing Date, and (B) a Preferential Right Notice to the holders of any such Preferential Rights in compliance with the terms of such rights and requesting waivers of such rights. Each Party shall provide the other Party with a copy of all notices sent to applicable Preferential Right and Consent holders. Each Party shall use commercially reasonable efforts to cause such Consents and waivers of Preferential Rights (or the exercise thereof) required to be requested pursuant to this Section 4.1(a) to be obtained and delivered prior to Closing. The Parties shall cooperate with each other in seeking to obtain such Consents and waivers of Preferential Rights, including providing reasonably requested financial and other information, and for the avoidance of doubt the Parties shall not and shall cause JVCo not to (I) take any action intended to frustrate the receipt of any Consent or waiver or (II) to cause any contract or agreement to become an Excluded Asset by refusing to take assignment thereof or refusing to grant any Consent or waiver.

(b) Any Preferential Right must be exercised subject to all terms and conditions set forth in this Agreement. The consideration payable under this Agreement for any particular

Asset for purposes of Preferential Right notices shall be the Agreed Allocated Value for such Asset.

(c) (i) If any Preferential Right is exercised prior to Closing, or (ii) if prior to the Closing, the time period in which the holder of a Preferential Right has the right to exercise such Preferential Right has not yet expired and such holder has not waived such Preferential Right, then, in each case (A) the Assets subject to such Preferential Right shall be excluded from the Assets to be conveyed to JVCo at Closing, (B) the MEPU Adjustment Amount or the PAI Adjustment Amount, as applicable, shall be adjusted upward by the Agreed Allocated Values of the Assets so excluded and (C) subject to Section 4.1(d), such Assets so excluded shall become Excluded Assets for all purposes hereunder.

(d) With respect to any Preferential Right described in Section 4.1(c)(i) or Section 4.1(c)(ii) above (i) if for any reason (A) the purchase and sale of the Assets covered by such Preferential Right is not or cannot be consummated with the holder of such Preferential Right in accordance with the instrument under which such Preferential Right arises, or (B) the holder of the Preferential Right is unable to satisfy the conditions to closing contained therein, or (ii) the period in which to exercise such Preferential Right has expired without the exercise thereof, then, in each case, the applicable Party shall promptly notify the other Party and, if less than 180 days have elapsed since the Closing Date, then, within ten (10) Business Days after the other Party’s receipt of such notice, the Parties shall conduct an additional closing whereby the applicable Party shall sell, assign and convey to JVCo, and the Parties shall cause JVCo to purchase and accept from such Party, such previously Excluded Assets (1) for the amount by which the MEPU Adjustment Amount or the PAI Adjustment Amount, as applicable, was adjusted at the initial Closing with respect to such Excluded Assets (subject to any applicable adjustments contained in Section 3.1 or Section 3.2 with respect to such Excluded Assets and any applicable closing conditions), (2) pursuant to an instrument in substantially the same form as the Conveyances, except the “Closing Date” with respect to any such Excluded Asset shall mean the date of assignment of such Excluded Asset from such Party to JVCo, and (3) thereafter, such previously Excluded Assets shall become Assets for all purposes hereunder.

(e) All Assets for which any applicable Preferential Right has been waived, or as to which the period to exercise the applicable Preferential Right has expired without the applicable Preferential Right having been validly exercised, in each case, prior to Closing, shall be transferred to JVCo at Closing pursuant to the provisions of this Agreement. With respect to any Preferential Right, until the Assets subject to such Preferential Right are transferred to JVCo pursuant to the provisions of this Agreement, each Party shall control any dispute between it and a holder of a Preferential Right with respect to such Preferential Right.

(f) If a Party fails to obtain a Consent prior to Closing and (i) the failure to obtain such Consent would cause (A) the assignment of the Assets affected thereby to JVCo to be void or voidable, (B) the termination of (or the right to terminate) a Lease or other Asset under the express terms thereof, or (C) any material Liability to the transferee of such Asset, (ii) the Consent requested by such Party is denied in writing, or (iii) the Consent is required from a Governmental Authority (other than a Customary Post-Closing Consent), the Parties shall execute and deliver such instruments and take such other actions as the Parties may mutually agree to carry out the intent of this Agreement and the transfer of the benefits and burdens of such Assets to JVCo. Such

instruments and actions may include the execution of back-to-back agreements to effect the transfer to JVCo of the benefits and burdens of such Assets which the Party whose Assets are subject to such Consent is obligated to perform and/or is entitled to receive, as applicable (provided that entering into such back-to-back agreements is not impracticable or does not: (x) result in a breach of any obligations under any such Assets, (y) result in a violation of Law or (z) impose a burden on such Party or JVCo disproportionate to the benefit received by JVCo under such Asset). In any such back-to-back agreement (whether in writing or otherwise), (i) such Party shall continue to be bound thereby and (ii) (A) such Party shall, without further consideration therefor, pay, assign and remit to JVCo promptly all monies, rights and other considerations received in respect of such Asset, (B) such Party shall continue to operate the Assets in compliance with Section 7.3, (C) such Party shall promptly exercise or exploit the beneficial rights and options of JVCo under such Asset at JVCo’s request and expense, (D) if and when any such Consent shall be obtained or such an Asset shall otherwise become assignable, such Party shall promptly assign, in a manner consistent with Section 2.2, its rights and obligations under such Asset to JVCo and the Parties shall cause JVCo, without the payment of any further consideration therefor, to assume such rights and obligations, and (E) the Parties shall cause JVCo to perform and discharge fully all of the obligations of such Party thereunder after the Effective Time and indemnify such Party for all Liabilities arising out of such performance by JVCo as if such obligations and Liabilities were Assumed Obligations hereunder; provided, however, JVCo shall not be required to indemnify such Party to the extent any such Liability arises from, or is attributable to (1) the gross negligence or willful misconduct of any MEPU Indemnified Party or PAI Indemnified Party, as applicable or (2) such Party’s breach of any provision of this Section 4.1(f). To the extent that a Party is unable to assign an Asset with respect to which this Section 4.1(f) applies, the Parties shall use commercially reasonable efforts to continue to seek the Consent applicable to such Asset until the earlier of (I) the third anniversary of the Closing Date or (II) the date such Asset terminates in accordance with its terms or otherwise at the direction of the other Party.

(g) Notwithstanding Section 4.1(f), the Parties may mutually agree prior to Closing, for JVCo to receive an assignment of Assets affected by Consents (including all Assets subject to or otherwise affected by such Consent), and such Assets shall be assigned to JVCo at Closing, and the Parties shall cause JVCo to indemnify the Party whose Assets are subject to such Consent for all Liabilities arising out of such assignment as if such Liabilities were Assumed Obligations hereunder.

(h) If a Party fails to obtain a Consent prior to Closing and (i) the failure to obtain such Consent would not cause (A) the assignment of the Asset (or portion thereof) affected thereby to JVCo to be void or voidable, (B) the termination of (or the right to terminate) a Lease or other Asset under the express terms thereof, or (C) any material Liability to the transferee of such Asset, (ii) such Consent requested by such Party is not denied in writing by the holder thereof, and (iii) such Consent is not required from a Governmental Authority (or is a Customary Post-Closing Consent) then, the Asset (or portion thereof) subject to such un-obtained Consent shall nevertheless be assigned by such Party to JVCo at Closing as part of the Assets.

(i) Prior to Closing, the Parties shall use their commercially reasonable efforts to obtain all Consents required to be requested pursuant to this Section 4.1 and waivers of all Preferential Rights; in addition, following the Closing, the Parties agree to use their commercially

reasonable efforts to cooperate with each other to obtain any Consents and waivers of Preferential Rights that were not obtained prior to Closing.

Section 4.2 Casualty or Condemnation Loss

(a) From the Execution Date until Closing, each Party shall provide written notice to the other Party of any (i) physical damage to a Well or any Equipment, and any Environmental Defect resulting therefrom or arising in connection therewith, that occurs and (A) is not the result of normal wear and tear, mechanical failure or gradual structural deterioration of materials, equipment, and infrastructure, or reservoir changes or depletion due to normal production (including (1) failures arising or occurring during drilling or completing operations, (2) junked or lost holes, or (3) sidetracking or deviating a well), and (B) is a result of acts of God, fire, explosion, pipeline or gathering line failure, earthquake, hurricane, tropical storm, tropical depression, storm, windstorm or blowout or (ii) any condemnation or other taking related to any Asset that occurs (each, a “Casualty Loss”) (provided that Casualty Loss shall not include any physical damage related to Decommissioning and NORM). Such written notice shall be provided promptly upon a Party becoming aware of any Casualty Loss and shall include, to the extent known by such Party at such time, (I) a reasonably detailed description of the events leading to such Casualty Loss, (II) a description of the Equipment and/or Wells affected by such Casualty Loss and (III) such Party’s estimate of the costs to repair or replace the Equipment and/or Wells affected by such Casualty Loss.

(b) From the Execution Date until Closing, should any Property suffer a Casualty Loss in an amount that exceeds Five Million Dollars $(5,000,000), net to the contributing or transferring Party’s interest in the applicable Property, then (subject to Section 8.1, Section 8.2 and Section 10.1) (the “Casualty Loss Threshold”) the other Party shall nevertheless be required to proceed to Closing and such Party may elect by written notice to the contributing or transferring Party prior to Closing to either (A) require such contributing or transferring Party, at such contributing or transferring Party’s sole cost, expense and Liability (to the extent the other Party does not otherwise own an interest in such Property), to repair or restore (or cause to be repaired or restored, including debris and wreck removal to the extent required by applicable Law) any such Property affected by such Casualty Loss to a quality and condition comparable to that existing with respect to such Property immediately before such Casualty Loss, as promptly as reasonably practicable (which work may extend after the Closing Date, so long as such contributing or transferring Party is diligently pursuing such repairs or restoration activities but not longer than one hundred eighty (180) days after the Closing Date unless mutually acceptable to the Parties) or (B) adjust the MEPU Adjustment Amount or the PAI Adjustment Amount, as applicable, by an amount that would be necessary to repair or restore (or cause to be repaired or restored, including debris and wreck removal to the extent required by applicable Law) any such Property affected by such Casualty Loss to a quality and condition comparable to that existing with respect to such Property immediately before such Casualty Loss. From the Execution Date until Closing, should any Property suffer a Casualty Loss in an amount less than the Casualty Loss Threshold, upon Closing, JVCo shall be entitled to all rights of the contributing or transferring Party to any insurance proceeds under insurance policies issued by Third Parties, to condemnation awards and to other claims against Third Parties with respect to the Casualty Loss; provided, however, that such contributing or transferring Party shall reserve and retain all rights, title, interests and claims against Third Parties for the recovery of such contributing or transferring Party’s costs and

expenses (if any) incurred prior to Closing in pursuing or asserting any such insurance claims or other rights against Third Parties with respect to such Casualty Loss.

(c) The Parties shall attempt to agree on the amount of the costs and expenses associated with Casualty Losses prior to Closing. Subject, and without prejudice, to Section 8.1(f) and Section 8.2(f), if the Parties are unable to reach an agreement by Closing, then a numerical average of each Party’s good faith estimate thereof shall be used for purposes of the Closing, and either Party may initiate binding arbitration in accordance with Section 12.10(c) within the 10-day period following the Closing Date to resolve the amount of the costs and expenses associated with Casualty Losses.

(iii) the Retained Liabilities of PAI; and

(iv) the Vantage Matter,

REGARDLESS OF FAULT.

(b) From and after Closing, MEPU shall indemnify, defend, and hold harmless PAI and its Affiliates, and all of its and their respective Representatives, successors and assigns (collectively, “PAI Indemnified Parties”) and JVCo from and against all Liabilities sustained or incurred by any person or entity or incurred in the investigation or defense of any of the same or in asserting, presenting or enforcing any of their respective rights hereunder arising from, based upon, related to or associated with:

(i) MEPU’s breach of any of its covenants or agreements contained this Agreement,

(ii) any breach of any representation or warranty made by MEPU pursuant to Article 5 or in the certificate delivered by MEPU at Closing pursuant to Section 9.2(l), and

(iii) the Retained Liabilities of MEPU,

REGARDLESS OF FAULT.

(c) From and after Closing, Transferors shall cause JVCo to indemnify, defend, and hold harmless each of the MEPU Indemnified Parties and the PAI Indemnified Parties from and against all Liabilities sustained or incurred by any person or entity or incurred in the investigation or defense of any of the same or in asserting, presenting or enforcing any of their respective rights hereunder arising from, based upon, related to or associated with the Assumed Obligations and the ownership of the Medusa Spar Units,

REGARDLESS OF FAULT.

(d) No Indemnified Party other than MEPU and PAI shall have any rights against MEPU, PAI or JVCo under the terms of this Section 11.2 except as may be exercised on its behalf by PAI or MEPU.

Section 11.3 Indemnification Actions. All claims for indemnification pursuant to this Agreement shall be asserted and resolved as follows:

(a) The term “Indemnifying Party” when used in connection with particular Liabilities shall mean the JV Party having an obligation to Indemnify another JV Party or Person(s) with respect to such Liabilities pursuant to this

Agreement, and the term “Indemnified Party” when used in connection with particular Liabilities shall mean the JV Party or Person(s) having the right to be indemnified with respect to such Liabilities by another JV Party pursuant to this Agreement.

(b) The term “REGARDLESS OF FAULT” MEANS WITHOUT REGARD TO THE CAUSE OR CAUSES OF ANY CLAIM, INCLUDING, EVEN THOUGH A CLAIM IS CAUSED IN WHOLE OR IN PART BY:

(i) THE NEGLIGENCE (WHETHER SOLE, JOINT, CONCURRENT, COMPARATIVE, CONTRIBUTORY, ACTIVE, PASSIVE, GROSS OR OTHERWISE), WILLFUL MISCONDUCT, STRICT LIABILITY OR OTHER FAULT OF ANY MEMBER OF THE PAI INDEMNIFIED PARTIES AND/OR THE MEPU INDEMNIFIED PARTIES, JVCO, INVITEES AND/OR THIRD PARTIES; AND/OR

(ii) A PRE-EXISTING DEFECT, WHETHER PATENT OR LATENT, OF THE ASSETS AND/OR EQUIPMENT.

(c) To make a claim for indemnification pursuant to this Agreement, an Indemnified Party shall notify the Indemnifying Party of its claim under this Section 11.3, 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 “Third Party Claim”), the Indemnified Party shall provide its Claim Notice promptly after the Indemnified Party has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 11.3 shall not relieve the Indemnifying Party of its obligations under this Agreement except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise materially prejudices the Indemnifying Party’s ability to defend against the Third Party 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 Third Party 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 Third Party Claim at the sole cost and expense of the Indemnifying Party. The Indemnified Party is authorized, prior to and during such 30 day period (or such shorter period until notification from the Indemnifying Party is received), at the expense of the Indemnifying Party, 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 to defend the Indemnified Party against a Third Party Claim, it shall have the right and obligation to diligently defend, at its sole cost and expense, such Third Party 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 good faith in contesting any Third Party Claim which the Indemnifying Party elects to contest (provided that in no event shall an Indemnified Party be obligated to bring any cross-complaint or counterclaim against any Person). The Indemnified Party may participate in, but not control, at its own expense, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 11.3(e). An Indemnifying Party shall not, without the written consent (which consent may not be unreasonably withheld) of the Indemnified Party, (i) settle any Third Party 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 Third Party Claim or (ii) settle any Third Party 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 to defend the Indemnified Party against the Third Party Claim, but fails to diligently prosecute or settle such Third Party Claim, then the Indemnified Party shall have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying Party (to the extent the Indemnified Party is entitled to indemnification hereunder), 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 Third Party Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet admitted its liability to defend the Indemnified Party against the Third Party 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 (10) days following receipt of such notice to (i) admit in writing its liability to indemnify the Indemnified Party from and against the Liability and consent to such settlement, (ii) if liability is so admitted, reject, in its reasonable judgment, the proposed settlement, or (iii) deny liability. If the Indemnified Party settles any Third Party Claim over the objection of the Indemnifying Party after the Indemnifying Party has timely admitted its obligation in writing and has actually assumed the defense of a Third Party Claim, the Indemnified Party shall be deemed to have waived any right to indemnity for such claim. Any failure by the Indemnifying Party to respond to such notice shall be deemed to be an election under subsection (i) above. Notwithstanding the other provisions of this Section 11.3, if the Indemnifying Party disputes its potential liability to the Indemnified Party under this Section 11.3 and if such dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party shall not be required to bear any costs and expenses of the Third Party Claim or the Indemnified Party’s defense pursuant to this Section 11.3 and, to the extent incurred by the Indemnifying Party, such costs and expenses shall be promptly reimbursed by the Indemnified Party.

(g) In the case of a claim for indemnification not based upon a Third Party 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.

(c) MEPU shall not have any liability for any indemnification under Section 11.2(b)(ii) for any Liability with a value of $350,000 or less, net to MEPU’s interest (and these types of Liabilities will not be counted in determining whether the $20,000,000 amount described below has been met), and MEPU shall have no Liability for any indemnification under Section

11.2(b)(ii) until and unless the aggregate amount of the liability for all such Liabilities under Section 11.2(b)(ii) for which Claim Notices are delivered by PAI on behalf of any PAI Indemnified Party or JVCo (and for which MEPU is responsible) exceeds $20,000,000, and then only to the extent such the aggregate Liabilities which are above such $350,000 threshold exceed $20,000,000, provided, however, that the indemnities under Section 11.2(b)(ii) for a breach of any Fundamental Representation shall not be limited by the provisions of this Section 11.4(c).

(d) PAI shall not have any liability for any indemnification under Section 11.2(a)(ii) for any Liability with a value of $350,000 or less, net to PAI’s interest (and these types of Liabilities will not be counted in determining whether the $20,000,000 amount described below has been met), and PAI shall have no Liability for any indemnification under Section 11.2(a)(ii) until and unless the aggregate amount of the liability for all such Liabilities under Section 11.2(a)(ii) for which Claim Notices are delivered by MEPU on behalf of any MEPU Indemnified Party or JVCo (and for which PAI is responsible) exceeds $20,000,000, and then only to the extent such the aggregate Liabilities which are above such $350,000 threshold exceed $20,000,000, provided, however, that the indemnities under Section 11.2(a)(ii) for a breach of any Fundamental Representation shall not be limited by the provisions of this Section 11.4(d). For the avoidance of doubt, the limitations in this Section 11.4(d) shall not apply to indemnity under Section 11.2(a)(iv).

(e) Notwithstanding anything to the contrary contained elsewhere in this Agreement, no Transferor shall be required to indemnify the other Transferor or JVCo under Section 11.2(a)(i) and Section 11.2(a)(ii), or Section 11.2(b)(i) and Section 11.2(b)(ii), as applicable, for aggregate Liabilities in excess of $1,000,000,000, provided, however, that the indemnities under Section 11.2(a)(ii) and Section 11.2(b)(ii) for a breach of any Fundamental Representation shall not be limited by the provisions of this Section 11.4(e). For the avoidance of doubt, the limitations in this Section 11.4(e) shall not apply to indemnity under Section 11.2(a)(iv).

(f) PAI’s liability for any indemnification under Section 11.2(a)(iv) shall be limited to $622,000,000 plus the amount of any reasonable attorneys’ fees, costs of investigation, defense, litigation, arbitration or other expenses incurred by the MEPU Indemnified Parties or JVCo.

(i) In no event shall any Indemnified Party be entitled to duplicate compensation with respect to the same Liability, loss, cost, expense, claim, award or judgment under more than one provision of this Agreement and the various documents delivered in connection with the Closing, or for which an Indemnified Party received the benefits of an adjustment to the MEPU Adjustment Amount or the PAI Adjustment Amount pursuant to Section 3.1 or Section 3.2, as applicable. Any Indemnified Party shall have a duty to mitigate the amount of any Liabilities for which such Indemnified Party is entitled to indemnity under this Article 11 by taking appropriate, commercially reasonable actions to reduce or limit the amount of such Liabilities.

(j) For purposes of this Article 11, any claim of, and Liability resulting from, any breach or inaccuracy in the representations and warranties under this Agreement and the corresponding representations and warranties given in the certificates to be delivered by Transferors at Closing pursuant to Section 9.2(l) and Section 9.3(h) shall be determined without regard to any materiality qualifiers in or affecting such representations or warranties.

SUBJECT TO THE PRECEDING SENTENCE, EACH OF MEPU, ON BEHALF OF ITSELF, THE MEPU INDEMNIFIED PARTIES AND JVCO, AND PAI, ON BEHALF OF ITSELF, THE PAI INDEMNIFIED PARTIES AND JVCO, WAIVES ANY RIGHT TO RECOVER INDIRECT, PUNITIVE, SPECIAL, INCIDENTAL, SPECULATIVE, EXEMPLARY AND CONSEQUENTIAL DAMAGES, INCLUDING DAMAGES FOR LOST PROFITS (WHETHER DIRECT OR INDIRECT) OR LOSS OF BUSINESS OPPORTUNITY, ARISING IN CONNECTION WITH OR WITH RESPECT TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 11.6 Exclusive Remedy and Release. Except for fraud, the indemnification remedies set forth in this Article 11 and the express rights of Transferors pursuant to Section 4.1, Section 4.2 and Section 10.2 (to the extent any such rights expressly survive the Closing pursuant to their terms), shall, from and after the Closing, constitute the sole and exclusive remedies of Transferors (including in their capacity as Members of JVCo) with respect to any and all Liabilities relating to the subject matter of this Agreement, including statutory or other claims arising under any Law. In furtherance of the foregoing, except for (a) claims made pursuant to the express indemnification provisions of this Article 11, (b) the express rights of Transferors pursuant to Section 4.1, Section 4.2 and Section 10.2 (to the extent any such rights expressly survive the

Closing pursuant to their terms) and (c) fraud, each Transferor hereby waives and releases, from and after the Closing to the fullest extent permitted by Law, any and all rights, Liabilities, and causes of action, with respect to the subject matter of this Agreement, it may have against the other Transferor, its respective Affiliates and their respective Representatives arising under or based upon any Law. Except for (a) claims made pursuant to the express indemnification provisions of this Article 11, (b) the express rights of Transferors pursuant to Section 4.1, Section 4.2 and Section 10.2 (to the extent any such rights expressly survive the Closing pursuant to their terms) and (c) fraud, PAI, on behalf of the PAI Indemnified Parties and JVCo, and MEPU, on behalf of the MEPU Indemnified Parties and JVCo, shall be deemed to have waived, to the fullest extent permitted under applicable Law, any right of contribution against such Transferor or any of its Affiliates and any and all rights, Liabilities and causes of action it may have against such Transferor or any of its Affiliates, arising under or based on any federal, state or local Law, common Law or otherwise. Notwithstanding the foregoing, nothing in this Section 11.6 shall prevent any Transferor from seeking injunctive or equitable relief in pursuit of its indemnification claims under this Article 11.

Section 11.7 Opportunity for Review. Each Transferor represents that it has had an adequate opportunity to review all waiver, release, indemnity and defense provisions in this Agreement, including the opportunity to submit the same to legal counsel for review and advice.

Any notice or communication given in accordance herewith shall be deemed to have been given when delivered to the addressee in person, or by courier, during normal business hours, or upon actual receipt by the addressee after such notice has either been delivered to an overnight courier or deposited in the United States Mail or sent electronically via email (provided that delivery of such email is confirmed by written confirmation), as the case may be. The Parties may change the addresses to which such notices or communications are to be addressed by giving written notice to the other Party in the manner provided in this Section 12.4.

Section 12.5 Sales or Use Tax, Recording Fees and Similar Taxes and Fees. Each Transferor shall pay 100% of, and will reimburse JVCo for, any sales, use, excise, real property transfer or gain, gross receipts, goods and services, registration, capital, documentary, stamp or transfer Taxes, recording fees and similar Taxes and fees incurred and imposed upon, or with respect to, the property transfers or other transactions contemplated hereby (“Transfer Taxes”) with respect to such Transferor’s Assets, other than any Transfer Taxes incurred and imposed upon, or with respect to a Transferor’s transfer to JVCo of pipe (“Pipe

Transfer Taxes”). The first $1,000,000 of any Pipe Transfer Taxes incurred by a Transferor shall be borne equally by each of the Transferors, and thereafter any additional Pipe Transfer Taxes shall be borne by the Transferor incurring such taxes; provided, that, for the avoidance of doubt, this clause only applies to Pipe Transfer Taxes. In the event that one Transferor is required to pay a portion of such Pipe Transfer Tax that it is not required to bear, the other Transferor will reimburse the paying Transferor for the portion of such Pipe Transfer Taxes that such nonpaying Transferor is required to bear. In the event that JVCo is required to pay any Pipe Transfer Taxes, each Transferor shall reimburse JVCo for the portion of such Pipe Transfer Taxes that such Transferor is required to bear. If such transfers or transactions are exempt from any such Taxes or fees upon the filing of an appropriate certificate or other evidence of exemption, such Transferor will timely furnish to the other Transferor such certificate or evidence. The Parties will reasonably cooperate as may be necessary to establish the applicability of any available Transfer Tax exemption (including, for the avoidance of doubt, any applicable isolated or occasional sale exemption).

Section 12.6 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any adverse manner to any Party. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

Section 12.7 Replacement of Bonds, Letters of Credit and Guarantees. The Parties understand that none of the bonds, letters of credit and guarantees, if any, posted by a Transferor or any of its Affiliates with any Governmental Authority or Third Party and relating to the Assets are to be transferred to JVCo. On or before Closing, Transferors shall cause to be obtained in the name of JVCo, replacements for such bonds, letters of credit and guarantees, to the extent such replacements are necessary to permit the cancellation of the bonds, letters of credit and guarantees posted by Transferors and such Affiliates or to consummate the transactions contemplated by this Agreement.

Section 12.8 Records Within thirty days of Closing, each Transferor, at its sole cost and expense, shall deliver or cause to be delivered to JVCo the Records. Transferors may retain copies of any or all of the Records, subject to their obligations under Section 7.2(b). Transferors agree to furnish or cause to be furnished to each other, upon request, as promptly as practicable, such information and assistance relating to the Assets, including access to books and records, as is reasonably necessary for the filing of all Tax Returns by Transferors, the making of any election relating to Taxes, the preparation for any audit by any Governmental Authority with respect to Taxes and the prosecution or defense of any claim, suit or proceeding relating to any Tax. Transferors shall, and shall cause JVCo to, retain all Records with respect to Taxes for a period of at least seven (7) years following the Closing Date (or such longer period as the statute of limitations for assessment of such Taxes remains open). Transferors shall retain all books and records with respect to Taxes pertaining to the Assets not included in the Records for a period of at least seven (7) years following the Closing Date (or such longer period as the statute of limitations for assessment of such Taxes remains open). Transferors shall cooperate fully with

each other in the conduct of any audit, litigation or other proceeding relating to Taxes involving the Assets, Allocable Amount, or Allocation Schedule.

Section 12.9 Governing Law; Jurisdiction; Venue; Jury Waiver

(a) THIS AGREEMENT, THE LEGAL RELATIONS AMONG THE PARTIES AND ALL DISPUTES OR CONTROVERSIES ARISING OUT OF, RELATING TO OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY SHALL BE GOVERNED EXCLUSIVELY BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS, EXCLUDING ANY CONFLICTS OF LAW RULE OR PRINCIPLE THAT MIGHT REFER CONSTRUCTION OF SUCH PROVISIONS TO THE LAWS OF ANOTHER JURISDICTION. SUBJECT TO THE REQUIREMENT THAT, UNLESS OTHERWISE PROVIDED HEREIN ALL DISPUTES UNDER THIS AGREEMENT, BE RESOLVED PURSUANT TO THE PROVISIONS SET FORTH IN Section 12.10, IN ANY ACTION TO ENFORCE ANY RIGHTS HEREUNDER, EACH OF THE PARTIES HERETO CONSENTS TO THE EXERCISE OF JURISDICTION IN PERSONAM BY THE UNITED STATES FEDERAL DISTRICT COURTS LOCATED IN HOUSTON, TEXAS (OR, ONLY IF THE FEDERAL DISTRICT COURTS DECLINE TO ACCEPT JURISDICTION OVER A PARTICULAR MATTER, THE STATE COURTS IN HOUSTON, TEXAS) AND ANY APPELLATE COURT THEREOF FOR ANY SUCH ACTION. ALL SUCH ACTIONS SHALL BE BROUGHT IN THE UNITED STATES FEDERAL DISTRICT COURTS HAVING SITES IN HOUSTON, TEXAS (OR, ONLY IF THE FEDERAL DISTRICT COURTS DECLINE TO ACCEPT JURISDICTION OVER A PARTICULAR MATTER, THE STATE COURTS IN HOUSTON, TEXAS) AND ANY APPELLATE COURT THEREOF. EACH PARTY HEREBY IRREVOCABLY CONSENTS TO THE SERVICE OF ANY PAPERS, NOTICES OR PROCESS AT THE ADDRESS SET OUT IN Section 12.4 IN CONNECTION WITH ANY SUCH ACTION AND AGREES THAT NOTHING HEREIN WILL AFFECT THE RIGHT OF THE OTHER PARTY TO SERVE ANY SUCH PAPERS, NOTICES OR PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW. EACH PARTY HERETO WAIVES ANY OBJECTION TO LAYING VENUE IN ANY SUCH ACTION IN SUCH COURTS AND WAIVES ANY OBJECTION THAT SUCH COURTS ARE AN INCONVENIENT FORUM OR DO NOT HAVE JURISDICTION OVER SUCH PARTY. EACH PARTY HERETO WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUCH ACTION.

(b) EACH OF THE PARTIES, FOR ITSELF OR ANY OF ITS ASSETS, HEREBY WAIVES ANY IMMUNITY TO THE FULLEST EXTENT PERMITTED BY THE LAWS OF ANY APPLICABLE JURISDICTION. THIS WAIVER INCLUDES IMMUNITY FROM: (I) JURISDICTION; (II) SERVICE OF PROCESS; (III) ANY LITIGATION, EXPERT DETERMINATION, MEDIATION, OR ARBITRATION PROCEEDING COMMENCED UNDER THIS AGREEMENT; (IV) ANY JUDICIAL, ADMINISTRATIVE OR OTHER PROCEEDINGS THAT ARE PART OF, OR IN AID OF, THE LITIGATION, EXPERT DETERMINATION, MEDIATION, OR ARBITRATION COMMENCED UNDER THIS AGREEMENT; AND (V) ANY EFFORT TO CONFIRM, ENFORCE, OR EXECUTE ANY DECISION, SETTLEMENT, AWARD, JUDGMENT, SERVICE OF PROCESS, EXECUTION ORDER OR ATTACHMENT (INCLUDING PRE-JUDGMENT ATTACHMENT) THAT

RESULTS FROM LITIGATION, EXPERT DETERMINATION, MEDIATION, ARBITRATION OR ANY JUDICIAL OR ADMINISTRATIVE PROCEEDINGS COMMENCED UNDER THIS AGREEMENT. FOR THE PURPOSES OF THIS WAIVER, EACH PARTY ACKNOWLEDGES THAT ITS RIGHTS AND OBLIGATIONS UNDER THIS AGREEMENT ARE OF A COMMERCIAL AND NOT A GOVERNMENTAL NATURE.

Section 12.10 Dispute Resolution

(a) Any dispute, controversy, cause of action or claim arising out of or in relation to or in connection with this Agreement, any documents contemplated to be executed hereunder, or the transactions contemplated hereby or thereby, whether sounding in contract, tort, statutory law, at common law, or in equity, including, any dispute as to the construction, validity, interpretation, enforceability or breach of this Agreement (each, a “Dispute”) (other than (i) a Dispute arising out of or in relation to or in connection with the calculation of the MEPU Adjustment Amount and the PAI Adjustment Amount, which shall be resolved in accordance with Section 9.4, or (ii) as set out in Section 4.2(c), which shall be resolved in accordance with Section 12.10(c)), on written request of either Transferor, shall be referred to representatives of the Transferors for decision, each Transferor being represented by a senior executive officer of the ultimate parent company of such Transferor who has no direct or operational responsibility for the matters contemplated by this Agreement (the “Negotiation Representatives”). The Negotiation Representatives shall promptly meet in a good faith effort to resolve the Dispute. If the Dispute is not resolved, as evidenced by the terms of a settlement reduced to writing and signed by the Transferors, within 30 calendar days after reference of the matter to them (or within such longer period of time as the Transferors may mutually agree in writing), either of the Transferors may submit the Dispute to non-binding mediation as provided in this Section 12.10.

(b) The Transferors agree that prior to attempting to resolve the Dispute by litigation, the Transferors may attempt to settle the Dispute by mediation in Houston, Texas under the then current International Institute for Conflict Prevention and Resolution Mediation Procedure, which procedure will be non-binding and confidential unless otherwise agreed by the parties. Within ten days of a Transferor’s written notice to the other Transferor of its desire to mediate, the non-requesting Transferor will provide a written response indicating whether it agrees to mediate. Within ten days of the non-requesting Transferor’s written notice to the requesting Transferor of its agreement to mediate, the parties will appoint a mutually acceptable mediator from the CPR Panels of Distinguished Neutrals.

(c) During the 10-day period following the Closing Date, the amount of costs and expenses associated with Casualty Losses in dispute shall be submitted to a consultant with at least ten (10) years’ experience in Gulf of Mexico oil and gas damage and insurance issues as selected by mutual agreement of the Parties or absent such agreement during the 10-day period, by the Houston, Texas office of the American Arbitration Association (the “Losses Arbitrator”). The arbitration proceeding shall be held in Houston, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section. The Losses Arbitrator’s determination shall be made within thirty (30) days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In

making his determination, the Losses Arbitrator may consider such matters as in the opinion of the Losses Arbitrator are necessary or helpful to make a proper determination. Additionally, the Losses Arbitrator may consult with and engage disinterested third parties to advise the arbitrator, including attorneys and engineers. In no event shall the amount of costs and expenses associated with a Casualty Loss as determined by the Losses Arbitrator be less than the amount asserted by the Party asserting the lower amount or greater than the amount asserted by the Party asserting the higher amount. The Losses Arbitrator shall act as an expert for the limited purpose of determining the amount of costs and expenses associated with Casualty Losses and may not award damages, interest or penalties to either Party with respect to any matter. Each Party shall bear its own legal fees and other costs of presenting its case. Each Party shall bear one-half of the costs and expenses of the Losses Arbitrator.

(d) All applicable statutes of limitation and defenses based upon the passage of time will be tolled for the duration of any Dispute resolution under this Section 12.10. All negotiations and mediations under this Section 12.10 shall be considered confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence. The Transferors shall continue to perform this Agreement pending the final resolution of any Dispute.

Section 12.11 Captions. The captions in this Agreement are for convenience only and shall not be considered a part of or affect the construction or interpretation of any provision of this Agreement.

Section 12.12 Waiver; Rights Cumulative. Any of the terms, covenants, representations, warranties or conditions hereof may be waived only by a written instrument executed by or on behalf of the Party waiving compli ance. No course of dealing on the part of any Party, or its respective Representatives, and no failure by a Party to exercise any of its rights under this Agreement shall operate as a waiver thereof or affect in any way the right of such Party at a later time to enforce the performance of such provision. No waiver by any Party of any condition, or any breach of any term, covenant, representation or warranty contained in this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such condition or breach or a waiver of any other condition or of any breach of any other term, covenant, representation or warranty. The rights of the Parties under this Agreement shall be cumulative, and the exercise or partial exercise of any such right shall not preclude the exercise of any other right.

Section 12.13 Assignment. No Party shall assign or otherwise transfer all or any part of this Agreement, nor shall any Party delegate any of its rights or duties hereunder, without the prior written consent of the other Party and any transfer or delegation made without such consent shall be void. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective successors and assigns.

Section 12.14 Entire Agreement. The Confidentiality Agreement, this Agreement and the documents to be executed hereunder and the Exhibits and Schedules attached hereto constitute the entire agreement between the Parties pertaining to the subject matter hereof, and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties pertaining to the subject matter hereof. In the event of any conflict between the provisions

of this Agreement and any of the documents contemplated to be executed hereunder or the Exhibits or Schedules, the provisions of this Agreement shall control.

Section 12.15 Amendment. This Agreement may be amended or modified only by an agreement in writing signed by each of MEPU and PAI and expressly identified as an amendment or modification.

Section 12.16 No Third Party Beneficiaries. Nothing in this Agreement shall entitle any Person other than Transferors to any claim, cause of action, remedy or right of any kind, except the rights expressly provided to the Persons described in Section 11.2(a), Section 11.2(b) or Section 11.2(c), subject to Section 11.2(d).
