If Closing occurs, the Deposit shall be applied toward the Adjusted Purchase Price at Closing as provided under Section 9.3(d).

(b) If (i) all conditions precedent to the obligations of Buyer set forth in Article VII (other than those actions or deliveries to occur at Closing) have been met or waived by Buyer, and (ii) the transactions contemplated by this Agreement are not consummated on or before the Closing Date because of: (A) the failure of Buyer to materially perform any of its obligations hereunder, or (B) the failure of any of Buyer’s representations or warranties hereunder to be true and correct in all material respects (other than representations and warranties qualified by materiality, including Material Adverse Effect, which shall be true and correct in all respects) as of the Closing, then, in such event, Seller shall have the right, as its sole and exclusive remedy, to either: (1) terminate this Agreement pursuant to Section 14.1(a), and

The parties hereby agree that the amount of the Deposit is a fair and reasonable estimation of Seller’s anticipated losses, damages and expenses that may be incurred as a result of such termination and therefore does not constitute a penalty. The parties, having bargained in good faith for such specific liquidated damages, are estopped from contesting the validity or enforceability of such liquidated damages after the Effective Time.

(c) If (i) all conditions precedent to the obligations of Seller set forth in Article VIII (other than those actions or deliveries to occur at Closing) have been met or waived by Seller, and (ii) the transactions contemplated by this Agreement are not consummated because of: (A) the failure of Seller to materially perform any of its obligations hereunder, or (B) the failure of any of Seller’s representations or warranties hereunder to be true and correct in all material respects (other than representations and warranties qualified by materiality, including Material Adverse Effect, which shall be true and correct in all respects) as of Closing, then, in such event, Buyer shall have the right, as its sole and exclusive remedy, to either: (1) terminate this Agreement pursuant to Section 14.1(b), and the Deposit shall be released to the Buyer from the Deposit Escrow Account in accordance with the Deposit Escrow Agreement, which Deposit shall constitute liquidated damages for any and all breaches of this Agreement by Seller, or (2) seek specific performance.

3.5 Preliminary Settlement Statement. Not less than five (5) Business Days prior to the Closing, Seller shall prepare and submit to Buyer for review a draft settlement statement (the “Preliminary Settlement Statement”) that shall set forth the Adjusted Purchase Price, reflecting each adjustment made in accordance with this Agreement as of the date of preparation of such Preliminary Settlement Statement and the calculation of the adjustments used to determine such amount, together with the designation of Seller’s accounts for the wire transfers of funds as set forth in Section 9.3(d). To the extent available, actual numbers shall be used in preparing the Preliminary Settlement Statement; however, if actual numbers are not available Seller shall use reasonable and good faith estimates, which estimates shall be adjusted to take into account actual numbers in connection with the Final Settlement Statement. Within three (3) Business Days of receipt of the Preliminary Settlement Statement, Buyer will deliver to Seller a written report containing all changes with the explanation therefor that Buyer proposes to be made to the Preliminary Settlement Statement. The Preliminary Settlement Statement, as agreed upon by the parties, will be used to adjust the Purchase Price at Closing. The parties shall attempt to agree on a final Preliminary Settlement Statement no later than one (1) Day prior to Closing. If the parties are unable to agree by that date, Seller’s estimate shall be used to determine the Adjusted Purchase Price.

3.6 Final Settlement Statement. On or before one hundred twenty (120) Days after the Closing, a final settlement statement (the “Final Settlement Statement”) will be prepared by Seller, based on actual income and expenses during the Interim Period and which takes into account all final adjustments made to the Purchase Price and shows the resulting final Purchase Price (“Final Price”). The Final Settlement Statement shall set forth the actual proration of the amounts required by this Agreement. As soon as practicable, and in any event within thirty (30) Days, after receipt of the Final Settlement Statement, Buyer shall return a written report containing any proposed changes to the Final Settlement Statement and an explanation of any such changes and the reasons therefor (the “Dispute Notice”). If Buyer fails to timely deliver the Dispute Notice to Seller, the statement as delivered by Seller will be deemed to be correct and will be final and binding on the parties and not subject to further audit or arbitration. If the Final Price set forth in the Final Settlement Statement is mutually agreed upon by Seller and Buyer, the Final Settlement Statement and the Final Price, shall be final and binding on the parties hereto. Any difference in the Adjusted Purchase Price as paid at Closing pursuant to the Preliminary Settlement Statement and the Final Price shall be paid by the owing party within ten (10) Days to the owed party. All amounts paid pursuant to this Section 3.6 shall be delivered in United States currency by wire transfer of immediately available funds to the account specified in writing by the relevant party.

document of twenty pages or less and submit such summaries to KPMG, or such other party as the parties may mutually select (the “Accounting Arbitrator”), together with the Dispute Notice, the Final Settlement Statement and any other documentation such party may desire to submit. Within twenty (20) business days after receiving the parties’ respective submissions, the Accounting Arbitrator shall render a decision choosing either Seller’s position or Buyer’s position with respect to each matter addressed in any Dispute Notice, based on the materials described above. Any decision rendered by the Accounting Arbitrator pursuant hereto 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. The costs of such Accounting Arbitrators shall be borne one-half by Buyer and one-half by Seller.

Buyer and Seller agree that the unadjusted Purchase Price shall be allocated among the Assets, in accordance with the principles of Section 1060 of the Code and the Treasury Regulations, 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. Buyer and Seller agree (i) that the Allocated Values, as adjusted, shall be used by Seller and Buyer as the basis for reporting asset values and other items for purposes of all federal, state, and local tax returns, including without limitation Internal Revenue Service Form 8594 and (ii) that neither they nor their Affiliates will take positions inconsistent with such Allocated Values in notices to Governmental Authorities, in audit or other proceedings with respect to taxes, in notices to preferential purchaser right holders, or in other documents or notices relating to the transactions contemplated by this Agreement.

(a) operate, or use commercially reasonable efforts to cause the operators thereof to operate, the Assets in the usual, regular and ordinary manner consistent with past practice;

(b) maintain the books of account and records relating to the Assets in the usual, regular and ordinary manner, in accordance with the usual accounting practices of each such Person;

of any such AFE and, except where immediate action is required under the circumstances or where such AFEs are issued for only informational purposes not allowing Seller an election to participate, obtain Buyer’s approval or disapproval with respect to whether Seller should elect to participate or not participate in the operations covered by such AFE (provided, that, approval of any AFE or election to participate contemplating expenditures in excess of $500,000 will require the approval of both parties);

(f) not enter into a Contract that if entered into prior to the date of this Agreement, would be required to be listed in a schedule attached to this Agreement, or terminate or materially amend or change the terms of any Material Contract;

Buyer acknowledges 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 6.1, 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 6.1.

ARTICLE XI

TITLE MATTERS; CASUALTIES; TRANSFER RESTRICTIONS

11.1 Seller’s Title.

(a) General Disclaimer of Title Warranties and Representations. Except for the special warranty of title as set forth in Section 11.1(b) and without limiting Buyer’s remedies for Title Defects set forth in this Article XI, Seller makes no warranty or representation, express,

implied, statutory or otherwise, with respect to Seller’s title to any of the Assets and Buyer hereby acknowledges and agrees that Buyer’s sole remedy for any defect of title, including any Title Defect, with respect to any of the Assets (i) before Closing, shall be as set forth in Section 11.2 and (ii) after Closing, shall be pursuant to the special warranty of title set forth in Section 11.1(b).

(b) Special Warranty of Title. If the Closing occurs, then effective as of the Closing Date, Seller warrants title to the Assets unto Buyer against every Person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under Seller or its Affiliates, but not otherwise, subject, however, to the Permitted Encumbrances; provided, however, that, except with respect to any liability of Seller for any claim asserted in writing by Buyer to Seller in accordance with Section 11.1(c) on or before the expiration of the Survival Period for breach of such special warranty, such special warranty shall cease and terminate at the end of such Survival Period. Buyer shall not be entitled to protection under Seller’s special warranty of title against any Title Defect reported by Buyer under Section 11.2, or any Title Defect actually known by Buyer prior to the Title Claim Date.

(c) Recovery on Special Warranty. Prior to the expiration of the one (1) year period commencing as of the Closing Date (the “Survival Period”), Buyer shall furnish Seller a notice setting forth any matters which Buyer intends to assert as a breach of Seller’s special warranty in Section 11.1(b). Seller shall have a reasonable opportunity, but not the obligation, to cure any title claim asserted by Buyer pursuant to this Section 11.1(c). Buyer agrees to reasonably cooperate with any attempt by Seller to cure any such title claim.

11.2 Notice of Title Defects; Defect Adjustments.

(a) Title Defect Notices. On or before June 26, 2013 (the “Title Claim Date”), Buyer must deliver claim notices to Seller meeting the requirements of this Section 11.2(a) (collectively the “Title Defect Notices” and individually a “Title Defect Notice”) setting forth any matters which, in Buyer’s reasonable opinion, constitute Title Defects and which Buyer intends to assert as a Title Defect pursuant to this Article XI. For all purposes of this Agreement and notwithstanding anything herein to the contrary, Buyer shall be deemed to have waived, and Seller shall have no liability for, any Title Defect which Buyer fails to assert as a Title Defect by a Title Defect Notice received by Seller on or before the Title Claim Date. To be effective, each Title Defect Notice shall be in writing, and shall include (i) a description of the alleged Title Defect(s), (ii) the Leases and Wells (and the applicable zone(s) therein) and/or other Assets affected by the Title Defect (each a “Title Defect Property”), (iii) the Allocated Value of each Title Defect Property, (iv) supporting documents reasonably necessary for Seller to verify the existence of the alleged Title Defect(s), and (v) the amount by which Buyer reasonably believes the Allocated Value of each Title Defect Property is reduced by the alleged Title Defect(s) and the computations upon which Buyer’s belief is based. To give Seller an opportunity to commence reviewing and curing Title Defects, Buyer agrees to use reasonable efforts to give Seller, on or before the end of each calendar week prior to the Title Claim Date, written notice of all Title Defects discovered by Buyer during the preceding calendar week, which notice may be preliminary in nature and supplemented prior to the Title Claim Date. Buyer shall also promptly furnish Seller with written notice of any Title Benefit which is discovered by any of Buyer’s or any of its Affiliate’s employees, title attorneys, landmen or other title examiners while conducting Buyer’s due diligence with respect to the Assets prior to the Title Claim Date.

(b) Title Benefit Notices. Seller shall have the right, but not the obligation, to deliver to Buyer on or before the Title Claim Date with respect to each Title Benefit a notice (a “Title Benefit Notice”) including (i) a description of the Title Benefit, (ii) the Leases and Wells (and the applicable zone(s) therein) affected by the Title Benefit, and (iii) the amount by which Seller reasonably believes the Allocated Value of those Leases and Wells (and the applicable zone(s) therein) is increased by the Title Benefit, and the computations upon which Seller’s belief is based. Except for purposes of defending against or paying any claim that Seller has breached its special warranty of title under Section 11.1(c), Seller shall be deemed to have waived all Title Benefits of which it has not given notice on or before the Title Claim Date.

(c) Seller’s Right to Cure. Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure at any time prior to Closing (the “Cure Period”), any Title Defects of which it has been advised by Buyer.

(d) Remedies for Title Defects. Subject to Seller’s continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto and subject to the rights of the parties pursuant to Section 14.1(f), in the event that any Title Defect timely asserted by Buyer in accordance with Section 11.2(a) is not waived in writing by Buyer or cured on or before Closing, Seller shall, at its sole option, elect to:

(i) subject to the Individual Title Defect Threshold and the Title Indemnity Deductible, reduce the Purchase Price by an amount (“Title Defect Amount”) determined pursuant to Section 11.2(g) or 11.2(j) as being the value of such Title Defect;

(ii) retain the entirety of the Title Defect Property that is subject to such Title Defect, together with all associated Assets, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Title Defect Property and such associated Assets; or

(iii) if applicable, terminate this Agreement pursuant to Section 14.1(f).

(e) Remedies for Title Benefits. With respect to each Lease and Well (or specified zone(s) therein) affected by Title Benefits reported under Section 11.2(b), the Purchase Price shall be increased by an amount (the “Title Benefit Amount”) equal to the increase in the Allocated Value for such Lease and Well caused by such Title Benefits, as determined pursuant to Section 11.2(h).

(f) Exclusive Remedy. Except for Seller’s special warranty of title under Section 11.1(b), Section 11.2(d) shall be the exclusive right and remedy of Buyer with respect to Seller’s failure to have Defensible Title with respect to any Asset.

(g) Title Defect Amount. The Title Defect Amount resulting from a Title Defect shall be the amount by which the Allocated Value of the affected Title Defect Property is reduced as a result of the existence of such Title Defect and shall be determined in accordance with the following terms and conditions:

(i) if Buyer and Seller agree on the Title Defect Amount, then that amount shall be the Title Defect Amount;

(ii) if the Title Defect is an Encumbrance, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Defect Property;

(iii) if the Title Defect represents a discrepancy between (A) the Net Revenue Interest for any Title Defect Property and (B) the Net Revenue Interest stated in Exhibit A and Exhibit B, then the Title Defect Amount shall be the product of the Allocated Value of such Title Defect Property multiplied by a fraction, the numerator of which is the Net Revenue Interest decrease and the denominator of which is the Net Revenue Interest stated in Exhibit A and Exhibit B;

(iv) if the Title Defect represents an obligation or Encumbrance upon or other defect in title to the Title Defect Property of a type not described above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property 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 Title Defect Property, the values placed upon the Title Defect by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation;

(v) the Title Defect Amount with respect to a Title Defect Property shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder; and

(vi) notwithstanding anything to the contrary in this Article XI, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Value of the Title Defect Property.

(h) Title Benefit Amount. The Title Benefit Amount resulting from a Title Benefit shall be determined in accordance with the following methodology, terms and conditions:

(i) if Buyer and Seller agree on the Title Benefit Amount, then that amount shall be the Title Benefit Amount; and

(ii) if the Title Benefit represents a discrepancy between (A) the Net Revenue Interest for any Lease or Well (or the specified zone(s) therein) and (B) the Net Revenue Interest stated in Exhibit A and Exhibit B, then the Title Benefit Amount shall be the product of the Allocated Value of such Lease or Well (or the specified zone(s) therein) multiplied by a fraction, the numerator of which is the Net Revenue Interest increase and the denominator of which is the Net Revenue Interest stated in Exhibit A and Exhibit B.

(i) Title Deductibles. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any individual Title Defect for which the Title Defect Amount does not exceed seventy-five thousand dollars ($75,000) (“Individual Title Defect Threshold”); and (ii) in no event shall there

be any adjustments to the Purchase Price or other remedies provided by Seller for any Title Defect that exceeds the Individual Title Defect Threshold unless (A) the sum of the Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold, in the aggregate, excluding any Title Defects cured by Seller, exceeds (B) the Title Indemnity Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price or other remedies only with respect to such Title Defects in excess of such Title Indemnity Deductible.

(j) Title Dispute Resolution. Seller and Buyer shall attempt to agree on all Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts prior to Closing. If Seller and Buyer are unable to agree by Closing, the Title Defect Amounts and Title Benefit Amounts in dispute shall be exclusively and finally resolved pursuant to this Section 11.1(j). There shall be a single arbitrator, who shall be a title attorney with at least ten (10) years experience in oil and gas titles involving properties on the Outer Continental Shelf, Gulf of Mexico, as selected by mutual agreement of Buyer and Seller within fifteen (15) Days after the end of the Cure Period, and absent such agreement, by the Houston office of the American Arbitration Association (the “Title 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 Article. The Title Arbitrator’s determination shall be made within twenty (20) 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 Title Arbitrator shall be bound by the rules set forth in Sections 11.2(g) and 11.2(h) and, subject to the foregoing, may consider such other matters as in the opinion of the Title Arbitrator are necessary to make a proper determination. The Title Arbitrator, however, may not award the Buyer a greater Title Defect Amount than the Title Defect Amount claimed by Buyer in its applicable Title Defect Notice and may not award Seller a greater Title Benefit Amount than the Title Benefit Amount claimed by Seller in its applicable Title Benefit Notice. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defect, Title Benefit, Title Defect Amounts and/or Title Benefit Amounts submitted by either party and may not award damages, interest or penalties to either party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each of Seller and Buyer shall bear one-half of the costs and expenses of the Title Arbitrator. To the extent that the award of the Title Arbitrator with respect to any Title Defect Amount or Title Benefit Amount is not taken into account as an adjustment to the Purchase Price pursuant to Section 3.5 or Section 3.6, then within ten (10) days after the Title Arbitrator delivers written notice to Buyer and Seller of his award with respect to a Title Defect Amount or a Title Benefit Amount, (i) Buyer shall pay to Seller the amount, if any, so awarded by the Title Arbitrator to Seller and (ii) Seller shall pay to Buyer the amount, if any, so awarded by the Title Arbitrator to Buyer.

11.3 Casualty or Condemnation Loss.

(a) Notwithstanding anything herein to the contrary, from and after the Effective Time, 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) Without limiting Buyer’s rights under Section 14.1(e), if, after the date of this Agreement but prior to the Closing Date, any portion of the Assets (including downhole) is destroyed by fire, windstorm or other casualty or is taken in condemnation or under right of eminent domain, and the aggregate amount of any such loss as a result of such casualty or taking exceeds fifteen percent (15%) of the Purchase Price, either party shall have the right to terminate this Agreement. If the aggregate amount of any such loss as a result of such casualty or taking exceeds fifteen percent (15%) of the Purchase Price and the parties nevertheless elect to 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 treat such casualty or taking as a Title Defect with respect to the affected Asset or Assets under Section 11.2. In each case, 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) Subject to and without limiting Buyer’s rights under Section 14.1(e), if, after the date of this Agreement but prior to the Closing Date, any portion of the Assets (including downhole) is destroyed by fire, windstorm or other casualty or is taken in condemnation or under right of eminent domain, and the aggregate amount of any such loss as a result of such casualty or taking is fifteen percent (15%) or less of the Purchase Price, Buyer shall nevertheless be required to close and Seller, at Closing, shall pay to Buyer all sums paid 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 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 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.

(d) 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.

11.4 Preferential Purchase Rights and Consents to Assign.

(a) With respect to each preferential purchase right pertaining to an Asset and the transactions contemplated hereby, Seller, prior to the Closing, shall send to the holder of each such right a notice, in material compliance with the contractual provisions applicable to such right. In addition, prior to the Closing, 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.

(b) If, prior to the Closing, any holder of a preferential purchase right notifies Seller that it intends to consummate the purchase of the Asset to which its preferential purchase right applies, the exercise of such preferential purchase right shall constitute a Title Defect, that Asset shall be excluded from the Assets to be conveyed to Buyer to the extent of the interest affected by the preferential purchase right, and the Purchase Price shall be reduced by the Allocated Value of the relevant Asset allocable to such interest. Seller shall be entitled to all proceeds paid by a party exercising a preferential purchase right prior to the Closing. If such holder of such preferential purchase right thereafter fails to consummate the purchase of the Asset covered by such right on or before thirty (30) Days following the Closing Date, then Seller shall so notify Buyer, and Buyer shall purchase on or before ten (10) Days following receipt of such notice, subject to Buyer’s satisfaction that such preferential right has been waived, such Asset from Seller, under the terms of this Agreement for a price equal to the portion of the Purchase Price previously allocated to it.

(c) If a preferential purchase right burdening any Asset is not exercised, or the time for exercising such preferential purchase right has not expired, prior to the Closing Date, then Buyer shall purchase such Asset subject to the preferential purchase right, and if such preferential purchase right is subsequently exercised, Buyer shall deliver the affected Asset to the holder of such preferential purchase right pursuant to an assignment in substantially the same form as the Assignment and shall keep the proceeds paid for such Asset by the party exercising the preferential purchase right.

(d) All Assets for which preferential purchase rights have been waived, or as to which the period to exercise such right has expired prior to the Closing, shall be sold to Buyer at the Closing pursuant to the provisions of this Agreement.

(e) If Seller fails to obtain a consent prior to the Closing (except for Customary Post-Closing Consents) and the failure to obtain such consent would cause the assignment of such Asset to Buyer to be void ab initio or the termination of a Lease, then the portion of the Assets subject to such failed consent shall constitute a Title Defect, that Asset shall be excluded from the Assets to be conveyed to Buyer to the extent of the interest affected by the consent, and the Purchase Price shall be reduced by the Allocated Value of the relevant Asset allocable to such interest. In the event that a consent (with respect to an Asset excluded pursuant to this Section 11.4(e)) that was not obtained prior to Closing is obtained prior to the date of delivery of the Final Settlement Statement, then, within ten (10) days after such Consent is obtained (x) Buyer shall purchase the Asset (or portion thereof) that was so excluded as a result of such previously un-obtained Consent and pay to Seller the amount by which the Purchase Price was reduced at Closing with respect to the Asset (or portion thereof) so excluded and (y) Seller shall assign to Buyer the Asset (or portion thereof) so excluded at Closing pursuant to an instrument in substantially the same form as the Assignment.

ARTICLE XII

ENVIRONMENTAL MATTERS

12.1 Environmental Defects.

(a) Assertions of Environmental Defects. Buyer must deliver claim notices to Seller meeting the requirements of this Section 12.1(a) (collectively the “Environmental Defect Notices” and individually an “Environmental Defect Notice”) not later than June 26, 2013 (the “Environmental Claim Date”) setting forth any matters which, in Buyer’s reasonable opinion, constitute Environmental Defects and which Buyer intends to assert as Environmental Defects pursuant to this Section 12.1. For all purposes of this Agreement, Buyer shall be deemed to have waived any Environmental Defect which Buyer fails to assert as an Environmental Defect by a Environmental Defect Notice received by Seller on or before the Environmental Claim Date. To be effective, each Environmental Defect Notice shall be in writing and shall include (i) a description of the matter constituting the alleged Environmental Defect, (ii) a description of each Asset (or portion thereof) that is affected by the alleged Environmental Defect, (iii) Buyer’s assertion of the Allocated Value of the portion of the Assets affected by the alleged Environmental Defect, (iv) supporting documents reasonably necessary for Seller to verify the existence of the alleged Environmental Defect, and (v) a calculation of the Remediation Amount (itemized in reasonable detail) that Buyer asserts is attributable to such alleged Environmental Defect. Buyer’s calculation of the Remediation Amount included in the Environmental Defect Notice must describe in reasonable detail the Remediation proposed for the Environmental Condition that gives rise to the asserted Environmental Defect and identify all assumptions used by the Buyer in calculating the Remediation Amount, including the standards that Buyer asserts must be met to comply with Environmental Laws. Seller shall have the right, but not the obligation, to cure any claimed Environmental Defect on or before Closing.

(b) Remedies for Environmental Defects. Subject to Seller’s continuing right to dispute the existence of a Environmental Defect and/or the Remediation Amount asserted with respect thereto, in the event that any Environmental Defect timely asserted by Buyer in accordance with Section 12.1(a) is not waived in writing by Buyer or cured on or before Closing, Seller shall, at its sole option, elect to:

(i) subject to the Individual Environmental Threshold and the Environmental Indemnity Deductible, reduce the Purchase Price by the Remediation Amount;

(ii) assume responsibility for the Remediation of such Environmental Defect;

(iii) retain the entirety of the Asset that is subject to such Environmental Defect, together with all associated Assets, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Asset and such associated Assets; or

(iv) if applicable, terminate this Agreement pursuant to Section 14.1(f).

If Seller elects the option set forth in clause (i) above, Buyer shall be deemed to have assumed responsibility for Remediation of such Environmental Defect and such Environmental Defect and all Liabilities with respect thereto shall be deemed to constitute Assumed Obligations. If Seller elects the option set forth in clause (ii) above, Seller shall use reasonable efforts to implement such Remediation in a manner which is consistent with the requirements of Environmental Laws in a timely fashion for the type of Remediation that Seller elects to undertake and shall have access to the affected Assets after the Closing Date to implement and complete such Remediation in accordance with an Access Agreement in substantially the form attached hereto as Exhibit E (the “Access Agreement”). Seller will be deemed to have adequately completed the Remediation required in the immediately preceding sentence (A) upon receipt of a certificate or approval from the applicable Governmental Authority that the Remediation has been implemented to the extent necessary to comply with existing regulatory requirements or (B) upon receipt of a certificate from a licensed professional engineer that the Remediation has been implemented to the extent necessary to comply with existing regulatory requirements.

(c) Exclusive Remedy. Subject to Section 14.1(f), Section 12.1(b) shall be the exclusive right and remedy of Buyer with respect to any Environmental Defect.

(d) Environmental Deductibles. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any individual Environmental Defect for which the Remediation Amount does not exceed seventy-five thousand dollars ($75,000) (“Individual Environmental Threshold”); and (ii) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any Environmental Defect for which the Remediation Amount exceeds the Individual Environmental Threshold unless (A) the sum of the Remediation Amounts of all such Environmental Defects that exceed the Individual Environmental Threshold, in the aggregate, excluding any Environmental Defects cured by Seller, exceeds (B) the Environmental Indemnity Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price or other remedies only with respect to such Environmental Defects in excess of such Environmental Indemnity Deductible.

(e) Environmental Dispute Resolution. Seller and Buyer shall attempt to agree on all Environmental Defects and Remediation Amounts prior to Closing. If Seller and Buyer are unable to agree by Closing, the Environmental Defects and/or Remediation Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 12.1. There shall be a single arbitrator, who shall be an environmental attorney with at least ten (10) years experience in environmental matters involving oil and gas producing properties in the Outer Continental Shelf, Gulf of Mexico, as selected by mutual agreement of Buyer and Seller within fifteen (15) Days after the Closing Date, and absent such agreement, by the Houston office of the American Arbitration Association (the “Environmental 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 Article. The Environmental Arbitrator’s determination shall be made within twenty (20) 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 Environmental Arbitrator shall be bound by the rules set forth in this Section 12.1 and, subject to the foregoing, may consider such other matters as in the opinion of the Environmental Arbitrator are necessary or helpful to make a proper determination. The Environmental Arbitrator, however, may not award the Buyer a greater Remediation Amount than the Remediation Amount

claimed by Buyer in its applicable Environmental Defect Notice. The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defects and/or Remediation Amounts submitted by either party and may not award damages, interest or penalties to either party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each of Seller and Buyer shall bear one-half of the costs and expenses of the Environmental Arbitrator. To the extent that the award of the Environmental Arbitrator with respect to any Remediation Amount is not taken into account as an adjustment to the Purchase Price pursuant to Section 3.6, then within ten (10) Days after the Environmental Arbitrator delivers written notice to Buyer and Seller of his award with respect to a Remediation Amount, and subject to Section 12.1, (i) Buyer shall pay to Seller the amount, if any, so awarded by the Environmental Arbitrator to Seller and (ii) Seller shall pay to Buyer the amount, if any, so awarded by the Environmental Arbitrator to Buyer.

12.2 NORM, Wastes and Other Substances. Buyer acknowledges that the Assets have been used for exploration, development, and production of oil and gas and that there may be petroleum, produced water, wastes, or other substances or materials located in, on or under the Assets or associated with the Assets. Equipment and sites included in the Assets may contain asbestos, NORM or other Hazardous Substances. NORM may affix or attach itself to the inside of wells, materials, and equipment as scale, or in other forms. The Wells, Personal Property, materials, and equipment located on the Assets or included in the Assets may contain NORM and other wastes or Hazardous Substances. NORM containing material and/or other wastes or Hazardous Substances may have come in contact with various environmental media, including without limitation, water, soils or sediment. Special procedures may be required for the assessment, remediation, removal, transportation, or disposal of environmental media, wastes, asbestos, NORM and other Hazardous Substances from the Assets.

ARTICLE XIII

13.7 Indemnification Procedures. All claims for indemnification under Sections 10.1(c), 13.2 and 13.3 shall be asserted and resolved as follows:

(a) 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.

(b) For purposes of this Article XIII, any breach of, or loss or Liability resulting from any breach or inaccuracy in the representations and warranties set forth in Article IV shall be determined without regard to any materiality qualifiers (including Material Adverse Effect) in or affecting such representations or warranties.

(c) To make claim for indemnification under Sections 10.1(c), 13.2 or 13.3, an Indemnified Party shall notify the Indemnifying Party of its claim under this Section 13.7, 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 13.7 shall not relieve the Indemnifying Party of its obligations under Sections 10.1(c), 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 thirty (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 thirty (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 13.7(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 (10) 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 thirty (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.

13.8 Survival.

(a) The representations and warranties of the parties in Articles IV and V (other than the Fundamental Representations and those representations and warranties in Sections 5.1, 5.2, 5.9, 5.10, and 5.11) and the covenants and agreements of the parties in Sections 6.1 and 9.4 shall survive the Closing for a period of twelve (12) months after the Closing Date. The special warranty of title provided for in Section 11.1 of this Agreement shall survive until the expiration of the Survival Period. Subject to the foregoing and as set forth in Section 13.8(b), the remaining representations, warranties, covenants and agreements of the parties (including, without limitation, the Fundamental Representations and those representations and warranties in Sections 5.1, 5.2, 5.9, 5.10, and 5.11) shall survive the Closing without time limit. Any reference to a representation or warranty in this Section 13.8(a) shall also be deemed to include a reference to the corresponding representations and warranties given in any certificate delivered by either party at Closing. Representations, warranties, covenants and agreements shall be of no further force and effect after the date of their expiration, provided that there shall be no termination of any bona fide claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to its expiration date.

(b) The indemnities in Sections 13.2(a), 13.2(b), 13.3(a) and 13.3(b) shall terminate as of the termination date of each respective representation, warranty, 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. Seller’ indemnity set forth in Section 13.2(c) shall terminate twelve (12) months after Closing; provided, however, that Seller’s indemnity obligation in Section 13.2(c) with respect to those Retained Liabilities set forth in Section 13.1(y)(i) and Section 13.1(y)(ii) shall survive the Closing without time limit. Buyer’s indemnity in Sections 13.3(c), and Seller’s indemnity set forth in Section 13.2(d) shall survive the Closing without time limit.

13.9 Waiver of Right to Rescission. Seller and Buyer acknowledge that the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant or agreement contained herein or for any other claim arising in connection with or with respect to the transactions contemplated in this Agreement. As the payment of money shall be adequate compensation, Buyer and Seller waive any right to rescind this Agreement or any of the transactions contemplated hereby.

13.10 Insurance, Taxes. The amount of any Liabilities for which any of the Buyer Indemnified Parties is entitled to indemnification under this Agreement or in connection with or with respect to the transactions contemplated in this Agreement shall be reduced by any corresponding (i) tax benefit created or generated or (ii) insurance proceeds realized or that could reasonably be expected to be realized by such party if a claim were properly pursued under the relevant insurance arrangements.

13.11 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 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, each waive any right to recover punitive, special, exemplary and consequential damages, arising in connection with or with respect to this Agreement or the transactions contemplated hereby.

13.12 Cooperation by Buyer - Retained Litigation. Buyer agrees to use reasonable efforts to cooperate with Seller in connection with Seller’s defense and other actions relating to or arising out of the litigation and claims set forth on Schedule 4.7 and Schedule 4.14. Buyer agrees to make available Buyer’s employees engaged in the operation of the Assets, for the purposes of providing testimony, depositions, information and other related activities relating to such litigation and claims.

13.13 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.
