If at the end of such thirty (30) day period (or earlier by mutual agreement) Buyer and Seller have not reached agreement on all such matters, Buyer and Seller may mutually agree to extend in writing the time to resolve any differences that they may have with respect to the matters specified in the Dispute Notice. In the absence of any such extension or upon the termination of any such extension without any additional extensions, either Party may submit any remaining Disputed Amounts to a recognized independent accounting firm reasonably agreed to by the Parties in writing (the “Referral Firm”) for review and resolution.

(ii) Not more than fifteen (15) days after the Parties have agreed upon the Referral Firm, each Party shall submit to the Referral Firm any supporting materials and calculations with regard to any Disputed Amounts in the Closing Statement.

With respect to any Disputed Amounts under this Agreement to be resolved by the Referral Firm, neither the Referral Firm nor any Person employed by the Referral Firm will interpret the provisions of this Agreement unless otherwise agreed by Seller and Buyer. With respect to any Disputed Amounts for which interpretation of this Agreement is required, and for which Buyer and Seller cannot agree on such interpretation, such interpretation of the Agreement shall be submitted to arbitration in a similar manner as set forth in Section 8 of Exhibit A regarding Title Defects and Environmental Defects.

(iii) The Referral Firm shall render a decision resolving the matters within thirty (30) days thereafter, unless the Parties reach prior agreement and withdraw the dispute from the Referral Firm. At the time the Referral Firm renders its decision, it shall provide a written statement of findings and conclusions regarding the Closing Statement and any disputed amounts set forth therein and shall issue a Final Closing Statement reflecting such decisions.

2.4 Defect Escrow. In the event that at the Closing there remains unresolved Title Defect or Environmental Defect and Seller elects to cure any such Title Defect or Environmental Defect after Closing pursuant to Section 3 of Exhibit A (“Post-Closing Curable Defect”), on the Closing Date Buyer shall deposit a portion of the Initial Purchase Price equal to the sum of such Title Defect Amounts and the Environmental Defect Amounts, as the case may be, attributable to such Post-Closing Curable Defects in immediately available funds (together with any interest accrued thereon, the “Post-Closing Defect Escrow Amount”) with the Escrow Agent to be held pursuant to the Escrow Agreement and this Agreement. If Seller and Buyer mutually agree in good faith that a Post-Closing Curable Defect has been cured at any time during the Cure Period, then within ten (10) days after such determination, the Post-Closing Defect Escrow Amount withheld with respect thereto shall be released to Seller in accordance with the terms of the Escrow Agreement. If, at the end of the Cure Period, Buyer and Seller agree that Seller has been unable to cure one or more of the Post-Closing Curable Defects, Buyer shall be entitled to the Post-Closing Defect Escrow Amount withheld with respect to such uncured Post-Closing Curable Defects, if any, which amount shall be deemed to be a reduction to the Final Purchase Price. If, at the end of the Cure Period, Seller and Buyer are unable to agree (a) whether Seller has cured a Post-Closing Curable Defect or (b) to the Title Defect Amount or Environmental Defect Amount attributable to a Post-Closing Curable Defect, then the applicable amount of funds in dispute, and accrued interest thereof, shall remain with the Escrow Agent pursuant to the Escrow Agreement until such disagreement shall be resolved as provided in Section 8 of Exhibit A.

No later than Closing, Buyer and Seller shall agree on a preliminary determination of the sales prices, which shall be based on the Initial Purchase Price and the Company’s liabilities that the Parties expect will be included in the amount realized for United States federal Income Tax purposes on the deemed sale of the Company’s assets. Buyer shall propose (subject to Seller’s review and comment) the preliminary determination to Seller no later than five (5) Business Days before the Closing Date, and once agreed upon, the preliminary determination shall be attached to this Agreement as Schedule 2.6.

If Seller provides such notice to Buyer, the Parties shall proceed in good faith to determine mutually the sales prices in dispute.

Seller and Buyer shall equally share all fees and any other charges of the Referral Firm. The Referral Firm shall be instructed to deliver to Seller and Buyer a written determination of the sales prices in dispute within twenty (20) days after the Parties’ submission of the disputed items to the Referral Firm. Such determination shall be conclusive and binding on the Parties. Notwithstanding the foregoing, the Parties shall mutually adjust the sales prices as determined hereunder (whether or not any matter has been referred to the Referral Firm) to the extent necessary to reflect any adjustment to the Final Purchase Price, as determined for United States federal Income Tax purposes. Neither Buyer nor Seller shall take, nor shall either permit any of their Affiliates (including, without limitation, the Company) to take, any position for Income Tax purposes that is inconsistent with the sales prices as finally determined hereunder.

(iii) Seller agrees to make available to Buyer and the Company records in the custody of Seller, to furnish other information and otherwise to cooperate to the extent reasonably required for the filing or audit of or other proceeding with respect to United States federal Income Tax Returns and Texas Margin Tax Returns relating to the Company for any taxable period ending after the Closing Date.

(iv) Seller agrees to cooperate with Buyer, and Buyer agrees to cooperate (and cause the Company to cooperate) with Seller, to the extent necessary in connection with the filing of any Tax Return relating to Buyer’s acquisition of the Company.

(e) After the Closing, this Article VII shall supersede any and all Tax-sharing or similar agreements to which (i) the Company, on the one hand, and (ii) Seller or any affiliated entity, on the other hand, are parties. Neither the Company, nor Seller or any such affiliated entity shall have any obligation or right with respect to each other under any such prior agreement after the Closing.

(f)

(i) Except as otherwise expressly provided in Section 7.1(a), Section 7.1(b), Section 7.1(c), or Section 7.1(f)(iii), (x) the Buyer and the Company (and not Seller) shall be responsible for preparing all other Tax Returns (including for the avoidance of doubt production and severance Taxes) due after the Closing Date, and any such Tax Returns that include any period before the Closing Date shall (except as otherwise required by law or expressly agreed to in writing by Seller and Buyer) be prepared on a basis consistent with prior Tax Returns relating to the same Tax; and (y) the Seller shall be responsible for preparing and filing all other Tax Returns (including for the avoidance of doubt production and severance Taxes) due after the Effective Date and on or before the Closing Date. Buyer and the Company shall not amend any Tax Return relating to a period ending on or before or including the Closing Date without the prior written consent of Seller, such consent not to be unreasonably withheld.

(ii) If the Company is required to file any Tax Return, other than those Tax Returns to which Section 7.1(a), Section 7.1(b), Section 7.1(c), or Section 7.1(f)(iii), apply, for a taxable period ending after the date of Closing but covering days before and after the Closing Date, Buyer or Seller, as the case may be, shall cause such returns to be filed and shall be responsible for payment of any Tax for such period. However, Seller shall pay to Buyer or Buyer shall pay to Seller, as appropriate, the amount by which the Tax attributable to the portion of the period through the Effective Date exceeds or is less than the sum of (i) amount of such Tax paid on or before the Effective Date and (ii) the amount of such Tax taken into account in computing the Initial Working Capital (the “Tax Adjustment”). This Section 7.1(f)(ii) shall not apply to Property Taxes, which shall be subject to Section 7.1(f)(iii). For purposes of this Section 7.1(f)(ii), the Tax attributable to the portion of the period through the Effective Date shall be determined as if the portion of the period through the Effective Date were a separate taxable period (i.e., by closing the books as of the Effective Date); provided, however, that in the case of any Tax that is a fixed amount for the entire taxable period, the Tax attributable to the portion of the period through the Effective Date shall be the product of such fixed amount and a fraction, the numerator of which is the number of days during the portion of the period through the Effective Date and the denominator of which is the number of days in the entire taxable period. Buyer shall compute the amount of the Tax Adjustment attributable to the portion of the period through the Effective Date, and shall notify Seller of such amount in writing no later than twenty (20) days after the filing of any Tax Return Buyer or Seller, as the case may be, is to cause to be filed under this Section 7.1.(f)(ii). Within twenty (20) days after such notification date, Seller shall pay to Buyer or Buyer shall pay to Seller, as appropriate, the Tax Adjustment, unless within twenty (20) days after such notification date, Seller notifies Buyer in writing that Seller disagrees with the computation of any such amount. In that case, Seller and Buyer shall proceed in good faith to determine the correct amount, and Seller’s payment to Buyer, or Buyer’s payment to Seller, shall be due the later of (i)the time specified in the

- 36 -

immediately preceding sentence or (ii) ten (10) days after Seller and Buyer agree to the amount payable. Seller shall be entitled to any refunds (including interest) of Taxes under Section 7.1(f)(ii) attributable to any period (or portion thereof) ending on or before the Effective Date except to the extent such refunds were included in the computation of the Tax Adjustments.

(iii) Ad valorem, on real and personal property Taxes (“Property Taxes”) attributable to the year of the Closing will be pro-rated as of the Effective Date with the Seller being liable for such Taxes attributable to the days in the Property Tax year through and including the Effective Date and the Buyer being liable for such Taxes attributable to days in the Property Tax year after the Effective Date. Such proration will be reflected in the calculation of the Initial Working Capital. Buyer shall promptly reimburse Seller for any Property Taxes paid by the Seller or the Company for any period (or portion thereof) beginning after the Effective Date. Proration of Property Taxes shall be made on the basis of the most recent Property Tax valuation and assessments of the assets owned by the Company. If such valuation pertains to a Property Tax period other than that in which the Closing occurs, within sixty (60) days of the issuance of the Tax ▇▇▇▇ covering the actual Property Tax period, Seller shall pay to Buyer or Buyer shall pay to Seller, as appropriate, the amount by which the prorated Property Tax exceeds or is less than the amount thereof taken into account in calculating the Initial Working Capital.

7.2 Seller’s Security. Buyer shall have in place as of the Closing sufficient surety bonds, cash collateral, letters of credit and guaranties, as applicable, to replace Seller’s Security. Buyer shall release or cause Seller’s Security to be released in full and unconditionally as of the Closing Date.

7.3 Non-Solicitation. Buyer agrees not to solicit or hire any employee of Seller or Seller Affiliate for a period of one (1) year from the Closing Date, except for employees of Seller or Seller’s Affiliate who are headquartered at locations within the State of Texas. The foregoing exception notwithstanding, to assure that Seller will maintain the benefits of certain of its employees until the expiration of the Cure Period and as necessary to provide any transition services that Seller may agree to provide to Buyer after the Closing Date, Buyer agrees (i) until the expiration of the Cure Period, except as otherwise approved by Seller in writing, to not solicit or hire any employee of Seller or Seller Affiliate that Seller, in its sole discretion, determines it requires to perform work necessary to cure any Title Defect or Environmental Defect (“Cure Employees”), (ii) to not hire any employee of Seller or Seller Affiliate that is performing any transition service to Buyer (“Transition Service Employees”), unless Buyer has notified Seller in writing that it will no longer require the specific transition service, or portion thereof, being provided by such employee, (iii) until after the Closing Date, to not hire any employee of Seller or Seller Affiliate who are headquartered at locations within the State of Texas (other than Cure Employees and Transition Service Employees) and (iv) if Closing does not occur, not solicit or hire any employee of Seller or Seller Affiliate, regardless of their location, for a period of one (1) year after termination of this Agreement. During the period between the date of this Agreement and the Closing Date, Buyer may enter into discussions with the employees referenced in Section 7.3 (i), (ii) and (iii) above regarding potential employment, provided that a representative of Seller is present during those discussions. After Closing Date and prior to the expiration of applicable non-solicitation period, Buyer may enter into discussions with the employees

- 37 -

referenced in Section 7.3 (ii) and (iii) above regarding potential employment. Solicitation for employment does not include general advertising for employment opportunities.” After the applicable non-solicitation period, Buyer may, at its sole discretion, decide to employ some or all of the individuals previously employed by Seller; however, Seller will not be involved in any way with Buyer’s evaluation or selection of candidates should Buyer decide to accept applications from any employees of Seller or Seller’s Affiliate.

7.4 Trademarks, Trade-Names, Signage. The trademarks and trade-names of Seller or any of its Affiliates, including but not limited to the word “DTE” (collectively, “Seller Marks”) appear on some of the properties and assets of the Company, including on signs at the offices of the Company, and on supplies, materials, stationary, brochures, advertising materials, manuals and similar consumable items of the Company. Buyer acknowledges and agrees that it does not have and, upon consummation of the transactions contemplated by this Agreement, will not have, any right, title, interest, license, or other right to use the Seller Marks. Buyer will (a) remove, within forty-five (45) days of Closing, the Seller Marks from, or cover or conceal the Seller Marks on, the properties and assets of the Company; (b) promptly ensure that all Oil and Gas Lease and Well identification signs relating to the Oil and Gas Leases and ▇▇▇▇▇ are updated to reflect Buyer as the operator of the ▇▇▇▇▇ and Oil and Gas Leases, (c) file amendments to the Company’s organizational documents, as amended, to change the name of the Company to remove the Seller Marks in accordance with this Section 7.4, and (d) submit notifications of change of name with respect to any permits or licenses of the Company to the extent that they use any Seller Marks.

ARTICLE VIII

8.1 Limitation on and Survival of Representations and Warranties.

(a) Buyer and Seller acknowledge and agree that no representations or warranties have been made by Buyer or Seller in connection with the transactions contemplated by this Agreement, except for those representations and warranties made in Article III and Article IV hereof.

(b) Subject to Section 8.1(a), all representations and warranties contained in this Agreement, or in any agreements or instruments executed in connection herewith or delivered pursuant hereto, shall survive the Closing for a period of one (1) year beginning on the Closing Date, except for (i) representations and warranties of Seller contained in Sections 3.1, 3.2, 3.3 and 3.4 and representations and warranties of Buyer contained in Sections 4.1 and 4.2 (collectively, “Fundamental Representations”), which shall survive the Closing without expiration, and (ii) representations and warranties contained in Section 3.9 which shall survive until sixty (60) days following the expiration of the applicable statute of limitations with respect to the underlying Tax claim (including any valid extensions). Such representations and warranties shall only be effective with respect to any breach or claim when notice of such breach or claim shall have been given in writing to the other Party in breach or against whom indemnification is sought within such applicable survival period. Any claim for indemnification

- 38 -

for which notice has been given within the prescribed period may be prosecuted to conclusion notwithstanding the subsequent expiration of such period.

8.2 Indemnification by Seller.

(a) Subject to the limitations set forth in Sections 8.1 and 8.5, Seller shall indemnify and hold Buyer and its employees, officers, directors and Affiliates (each a “Buyer Indemnified Party”) harmless from and against any and all claims, demands, suits, proceedings, judgments, losses, liabilities, damages, costs and expenses, including, but not limited to, reasonable attorneys’ fees, but excluding as described in Section 11.10, any consequential, incidental, punitive damages, lost profits or speculative damages except to the extent arising pursuant to a third party claim therefor (collectively, “Losses”) imposed upon or incurred by any Buyer Indemnified Party as a result of or in connection with any of the following:

(i) any breach of a representation or warranty made by Seller in Article III, except with respect to Taxes, a breach of a representation or warranty made under Section 3.9 shall be limited to all Taxes other than Taxes specified in (iii) below; or

(ii) the breach of, or default in the performance by Seller of, any covenant, agreement or obligation to be performed by Seller pursuant to this Agreement; or

(iii) Any United States Income Taxes, Texas Margin Taxes and other Taxes provided in Section 7.1(f) for which Seller is liable pursuant to Section 7.1.

Buyer covenants that it shall not solicit or encourage third parties to commence any proceedings or make any claims for which a Buyer Indemnified Party would be entitled to indemnification under this Section 8.2(a) and shall not disclose any information with the intent of soliciting or encouraging third parties to commence such proceedings or make such claims.

(b) Within thirty (30) days after receipt by a Buyer Indemnified Party of notice of the commencement of an Action or other event giving rise to a buyer claim with respect to which a Buyer Indemnified Party may be entitled to indemnification under this Section 8.2 (a “Buyer Claim”), the Buyer Indemnified Party receiving such notice shall notify (the “Buyer Claim Notice”) Seller in writing of the commencement of such Action or the assertion of such Buyer Claim; provided, however, that failure to give such notice shall not relieve Seller of its obligations hereunder (i) unless the Buyer Indemnified Party fails to deliver a proper Buyer Claim Notice prior to the date specified in Section 8.1(b), or (ii) unless and only to the extent that Seller is materially prejudiced thereby. Seller shall have the option, and shall notify Buyer Indemnified Party in writing within ten (10) Business Days after the date of a Buyer Claim Notice of their election, either: (A) to participate (at the expense of Seller) in the defense of such Action or Buyer Claim (in which case the defense of such Action or Buyer Claim shall be controlled by Buyer Indemnified Party) or (B) to take charge of and control the defense of such Action or Buyer Claim (at the expense of Seller). If Seller elects to control the defense, it will not compromise or settle the Action or Buyer Claim if (x) the amount to be paid in settlement, when aggregated with other Buyer Claims, exceeds the Maximum Indemnity Amount, as defined below, or (y) the settlement does not include a provision releasing Buyer Indemnified Party from

- 39 -

all liabilities with respect thereto. If Seller fails to notify Buyer Indemnified Party of its election within the applicable response period, then Seller shall be deemed to have elected not to control the defense of such Action or Buyer Claim. If Seller elects to control the defense of any Action or Buyer Claim, Buyer Indemnified Party shall have the right to employ separate counsel and participate in the defense of such Action or Buyer Claim, but the fees and expenses of such counsel shall be at the expense of Buyer Indemnified Party unless: (1) the named parties in such Action or Buyer Claim (including any impleaded parties) include both Buyer Indemnified Party and Seller and Buyer Indemnified Party shall have been advised by such counsel that there may be one or more legal defenses available to it that are different from or additional to those available to Seller, or (2) Buyer Indemnified Party has reasonably determined that Losses that may be incurred may exceed either individually, or when aggregated with other Buyer Claims, the Maximum Indemnity Amount (in which case, Seller shall not have the right to control the defense of such Action or Buyer Claim on behalf of Buyer Indemnified Party, it being understood, however, that Seller shall not, in connection with such Action or Buyer Claim, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) and that all such fees and expenses shall be reimbursed as they are incurred).

(c) If Seller does not control the defense of any Action or Buyer Claim, then Buyer Indemnified Party may settle such Action or Buyer Claim with the prior written consent of Seller (not to be unreasonably withheld).

8.3 Indemnification by Buyer.

(a) Subject to the limitations set forth in Sections 8.1, 8.5 and 11.10, Buyer shall indemnify and hold harmless Seller its Affiliates (other than the Company), each of their respective past, present and future directors, officers, employees, consultants and agents, each of the Company’s past and present (and, through the Closing, future) directors, officers, employees, consultants and agents), and each of the directors, officers, heirs, executors, successors and assigns of any of the foregoing (each a “Seller Indemnified Party”) harmless from and against any and all Losses imposed upon or incurred by any Seller Indemnified Party as a result of or in connection with any of the following:

(i) any breach of a representation or warranty made by Buyer in Article IV; or

(ii) the breach of or default in the performance by Buyer or Buyer Parent of any covenant, agreement or obligation to be performed by Buyer or Buyer Parent pursuant to this Agreement.

(b) Within thirty (30) days after receipt by a Seller Indemnified Party of notice of the commencement of an Action or other event giving rise to a seller claim with respect to which a Seller Indemnified Party may be entitled to indemnification (a “Seller Claim”), the Seller Indemnified Party receiving such notice shall notify (the “Seller Claim Notice”) Buyer in writing of the commencement of such Action or the assertion of such Seller Claim; provided, however, that failure to give such notice shall not relieve Buyer of its obligations hereunder (i) unless the Seller Indemnified Party fails to deliver a proper Seller Claim Notice prior to the date specified in Section 8.1(b) or (ii) unless and only to the extent that Buyer is materially prejudiced

- 40 -

thereby. Buyer shall have the option, and shall notify each indemnified Party in writing within 10 Business Days after the date of a Seller Claim Notice of its election, either: (A) to participate (at its own expense) in the defense of the Action or Seller Claim (in which case the defense of such Action or Seller Claim shall be controlled by Seller Indemnified Party) or (B) to take charge of and control defense of such Action or Seller Claim (at its own expense). If Buyer fails to notify Seller Indemnified Party of its election within the applicable response period, then Buyer shall be deemed to have elected not to control the defense of such Action or Seller Claim. If Buyer elects to control the defense of any Action or Seller Claim, each Seller Indemnified Party shall have the right to employ separate counsel and participate in the defense of any such Action or Seller Claim, but the fees and expenses of such counsel shall be at the expense of Seller Indemnified Party unless: (1) the named parties in such Action or Seller Claim (including any impleaded parties) include both Seller Indemnified Party and Buyer and Seller Indemnified Party shall have been advised by such counsel that there may be one or more legal defenses available to it that are different from or additional to those available to Buyer, or (2) Seller has reasonably determined that Losses that may be incurred may exceed either individually, or when aggregated with other Seller Claims, the Maximum Indemnity Amount (in which case, Buyer shall not have the right to assume the defense of such Action or Seller Claim on behalf of Seller Indemnified Party, it being understood, however, that Buyer shall not, in connection with such Action or Seller Claim be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) and that such fees and expenses shall be reimbursed as they are incurred).

(c) If Buyer does not control the defense of any Action or Seller Claim, then Seller Indemnified Party may settle such Action or Seller Claim with the prior written consent of Buyer (not to be unreasonably withheld).

8.4 Consent to Settlement; Cooperation. Either Buyer or Seller, as the case may be (each an “Indemnifying Party”), in the defense of any claim or litigation, shall not, except with the consent of the Buyer Indemnified Party or Seller Indemnified Party as the case may be (which consent shall not be unreasonably withheld, delayed or conditioned), consent to entry of any judgment or enter into any settlement which (a) does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Buyer Indemnified Party or Seller Indemnified Party of a full and unconditional release from all liability in respect of such claim or litigation or (b) with respect to a claim settled by Seller as Indemnifying Party, contains any term that would restrict the operations or activities of the Company or any Buyer Indemnified Party. A Buyer Indemnified Party or Seller Indemnified Party, as the case may be, shall furnish such information regarding itself or the claim in question as the Indemnifying Party, may reasonably request in writing and as shall be reasonably required in connection with the defense of such claim and litigation resulting therefrom.

8.5 Limitation of Liability.

(a) Notwithstanding the foregoing, (i) Seller shall not be obligated to indemnify Buyer Indemnified Parties, and Buyer shall not be obligated to indemnify Seller Indemnified Parties pursuant to this Article VIII unless and until the amount of all Losses incurred by Buyer, or by Seller, as the case may be, exceeds three percent (3%) of the Initial Purchase Price in the aggregate (the “Basket”), in which event the Party seeking indemnity may

- 41 -

recover Losses incurred in excess of the Basket from the first dollar above the Basket, and (ii) Seller’s maximum liability for Losses under Section 8.2 and Buyer’s maximum liability for Losses under Section 8.3 shall be, in each case, twenty percent (20%) of the Initial Purchase Price (the “Maximum Indemnity Amount”). Notwithstanding the foregoing, (w) Buyer’s obligation pursuant to Seller’s Security in Section 7.2, (x) each Party’s obligation pursuant to Sections 8.2(a)(i) and 8.3(a)(i), respectively, with respect to breach of any Fundamental Representation, (y) Seller’s (i) obligation pursuant to Section 8.2(a)(iii) and (ii) the covenant set forth in Section 5.10, and (z) each Party’s obligations pursuant to Section 11.2, (collectively, “(w)-(z)”), shall not be subject to the Basket or the Maximum Indemnity Amount.

(b) Notwithstanding the foregoing, the Buyer Indemnified Parties shall not be entitled to indemnification pursuant to this Article VIII with respect to any inaccuracy or breach of any representation and warranty or covenant by Seller or of the Company that is contained herein if, at or before the time of Closing, Buyer, Buyer Parent or any of their representatives, attorneys, accountants or agents had actual knowledge of the misrepresentation or breach of warranty or covenant or any of the facts underlying such breach.

(c) Notwithstanding the foregoing, the Buyer Indemnified Parties shall not be entitled to indemnification pursuant to this Article VIII to the extent the matter in question, taken together with all similar matters, does not exceed the amount of any reserves or liabilities with respect to such matters that are reflected in the Closing Statement and taken into account in the calculation of the Final Purchase Price.

(d) The amount of any recovery by any Buyer Indemnified Party pursuant to this Article VIII shall be reduced by the amount of insurance proceeds paid to any Buyer Indemnified Parties under any applicable insurance policy and the amount of indemnification and other payments paid to any Buyer Indemnified Parties under any applicable indemnification agreements or similar rights as a result of the facts that entitled any Buyer Indemnified Parties to recover from Buyer. Each Buyer Indemnified Party shall make all claims under applicable insurance policies (other than self-insurance policies), indemnification agreements and similar rights and to seek recovery under all applicable insurance policies, indemnification agreements and similar rights for all Losses to the extent such Losses are covered by any insurance policy, indemnification agreement or similar right; provided, that such Buyer Indemnified Party’s right to indemnification hereunder shall not be affected by such obligation.

(e) The amount of any recovery by any Buyer Indemnified Party pursuant to this Article VIII shall be reduced by the amount of any net refund of Taxes paid or reduction in the amount of Taxes that the Buyer Indemnified Parties are reasonably expected to realize as a result of the incurrence or payment of any such Losses.

(f) The amount of any recovery by any Buyer Indemnified Party pursuant to this Article VIII shall be reduced by the amount of any net refund of Taxes paid or reduction in the amount of Taxes that the Buyer Indemnified Parties actually realize as a result of the incurrence or payment of any such Losses.

8.6 Exclusive Remedy. Except for remedies that cannot be waived as a matter of Law and injunctive and provisional relief (including specific performance) and except in the case

- 42 -

of fraud or willful misconduct, if the Closing occurs, indemnification pursuant to the provisions of this Article VIII shall be the sole and exclusive remedy of the Parties with respect to any matters arising under or relating to this Agreement, any Closing document executed and delivered pursuant to the provisions hereof and the transactions contemplated by this Agreement, and the only legal action that may be asserted by any Party with respect to any matter that is the subject of this Article VIII shall be a contract action to enforce, or to recover Losses for the breach of, this Article VIII. Without limiting the generality of the preceding sentence, no legal action sounding in tort or strict liability may be maintained by any Party, except in the case of fraud or willful misconduct.

8.7 Title Defects and Environmental Defects. Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to the Company’s title to any of the Company Assets and Buyer hereby acknowledges and agrees that Buyer’s sole remedy for (i) any defect of title, including any Title Defect, with respect to any of the Assets and (ii) Environmental Defects, in each case, shall be pursuant to the procedures set forth in Exhibit A, except as expressly provided herein to the contrary, such remedy shall cease and be deemed to be finally and conclusively satisfied, in all respects upon the Closing.

8.8 Disclaimer of Other Warranties.

(a) The express representations and warranties of Seller contained in this Agreement are exclusive and are in lieu of all other representations and warranties, express, implied, or statutory. EXCEPT AS SET FORTH IN THIS AGREEMENT, NO EXPRESS, STATUTORY, OR IMPLIED WARRANTY OR REPRESENTATION OF ANY KIND IS MADE BY SELLER OR THE COMPANY, INCLUDING BUT NOT LIMITED TO WARRANTIES OR REPRESENTATIONS RELATING TO:

ARTICLE IX

TERMINATION

9.1 Termination. This Agreement may be terminated by written agreement, and the transactions contemplated by this Agreement may be abandoned at any time prior to the Closing only as follows:

- 45 -

(a) by mutual written agreement of Buyer and Seller;

(b) by Buyer or Seller, if the Closing shall not have occurred on or before December 31, 2012, except that Buyer and Seller shall have the right, in their mutual discretion, to extend this time period in this Section 9.1(b); provided that the right to terminate this Agreement pursuant to this Section 9.1(b) shall not be available to a Party whose failure to perform any of its obligations required to be performed under this Agreement prior to Closing resulted in the failure of the Closing to be consummated by such date;

(c) by Buyer or Seller, if any court of competent jurisdiction in the United States or other United States Governmental Authority shall have issued an order, decree or ruling or taken any other action restraining, enjoining or otherwise prohibiting the transactions contemplated hereby and such order, decree, ruling or other action shall have become final and non-appealable;

(d) by Buyer or Seller, if the aggregate amount of the agreed-upon Title Defects and Environmental Defects exceeds fifteen percent (15%) of the Initial Purchase Price;

(e) by Buyer, by written notice to Seller, if Seller breaches or fails to perform its representations, warranties or covenants contained in this Agreement, which breach or breaches or failure or failures to perform (i) would, individually or in the aggregate, give rise to the failure of a condition set forth in Section 6.2(a) or Section 6.2(b) and (ii) cannot be cured or, if curable, is not or are not cured within thirty (30) days after written notice from Buyer; or

(f) by Seller, by written notice to Buyer, if Buyer breaches or fails to perform its representations, warranties or covenants contained in this Agreement, which breach or breaches or failure or failures to perform (i) would, individually or in the aggregate, give rise to the failure of a condition set forth in Section 6.3(a) or Section 6.3(b) and (ii) cannot be cured or, if curable, is not or are not cured within thirty (30) days after written notice from Seller.

9.2 Effect of Termination.

Nothing contained in this Section 9.2 shall relieve any Party from liability for any willful failure to perform or observe in any material respect any of its agreements or covenants contained herein or willful breach of any representations or warranties, that are to be performed or observed at or prior to the Closing. In the event this Agreement terminates under Section 9.1 and any Party has willfully failed to perform or observe in any material respect any of its agreements or covenants contained herein or willfully breached any of its representations or warranties, which are to be performed or observed at or prior to the Closing, then the other Party, subject to Section 11.10, shall be entitled to all remedies available at law or in equity and shall be entitled to recover court costs and attorneys’ fees in addition to any other relief to which the other Party may be entitled.

EXHIBIT A

PROCEDURE FOR CLAIMING

TITLE DEFECTS AND ENVIRONMENTAL DEFECTS AND ADJUSTING THE BASE

PURCHASE PRICE

1. Examination Period and Access to Information

(a) From the date of this Agreement until noon Central Time on December 17, 2012 (the “Examination Period”), Seller will afford to Buyer and its representatives reasonable access during normal business hours to the offices, personnel and books and records of Seller and/or the Company in order for Buyer to conduct a title examination and environmental examination as it may in its sole discretion choose to conduct with respect to (i) the Properties, in order to determine whether Environmental Defects exist and (ii) the Oil and Gas Leases and ▇▇▇▇▇ set forth on Schedule 3.18(f)(i) in order to determine whether Title Defects exist.

(b) Buyer and its representatives may examine all abstracts of title, title opinions, title files, ownership maps, lease files, assignments, division orders, operating records and agreements, well files, financial and accounting records, geological, geophysical, engineering and environmental records, in each case insofar as the same may now be in existence and in the possession of Seller or the Company, provided, however, that Seller and the Company may withhold access to (a) all legally privileged documents and (b) information that Seller or the Company is prohibited from disclosing by bona fide, third party confidentiality restrictions; provided further that Seller will use, and will cause the Company to use, its reasonable efforts to obtain a waiver of any such restrictions in favor of Buyer. The cost and expense of Buyer’s review of the title to the Oil and Gas Leases or ▇▇▇▇▇ and environmental condition of the Properties will be borne solely by Buyer. Buyer will not contact any of the customers or suppliers of the Company or its Working Interest co-owners, operators, lessors or surface interest owners, in connection with the transactions contemplated hereby, whether in person or by telephone, mail or other means of communication, without the specific prior authorization of Seller, which consent will not be unreasonably withheld. Buyer will indemnify and hold harmless Seller and the Company and their respective officers, directors, agents, representatives, employees, successors, and assigns against any damages arising from or in connection with Buyer’s due diligence examination of title to the Oil and Gas Properties or the environmental condition of the Properties.

2. Notice of Asserted Title Defects and Environmental Defects. If Buyer discovers any Title Defect affecting any of the Oil and Gas Leases or ▇▇▇▇▇ or Environmental Defect affecting any of the Properties, Buyer may notify Seller of such alleged Title Defect or Environmental Defect prior to the expiration of the Examination Period, provided, that such allegation is made in good faith. To be effective, such notice (“Title Defect Notice” or “Environmental Defect Notice,” respectively) must

(a)

be in writing;

(b)

be received by Seller prior to the expiration of the Examination Period;

Page 1

(c)

describe the Title Defect or Environmental Defect in reasonable detail including the basis therefore (including any alleged variance in the Net Revenue Interest or Working Interest of any alleged Title Defect) and any supporting documents;

(d)

identify the specific Title Defect Property or Environmental Defect Property (as defined below) to which such Title Defect or Environmental Defect relates; and

(e)

include the value of such Title Defect Amount or Environmental Defect Amount as determined by Buyer in good faith and in accordance with Section 6 of this Exhibit A.

Notwithstanding anything to the contrary herein, at the end of the Examination Period, any matters that may otherwise constitute a Title Defect or Environmental Defect, but of which Seller has not been specifically notified by Buyer in accordance with the foregoing, will be deemed to have been waived by Buyer for all purposes.

3. Cure. Upon the receipt of an effective Title Defect Notice or Environmental Defect Notice from Buyer, Seller will have the option, but not the obligation, to attempt to cure such Title Defect or Environmental Defect during the Cure Period (as hereinafter defined) at Seller’s sole cost and expense.

4. A property affected by such Title Defect or Environmental Defect will be referred to as “Title Defect Property” or “Environmental Defect Property,” respectively.

5. Title Defect.

(a) As used in this Exhibit A, “Title Defect” means, for each Oil and Gas Property, any condition other than a Permitted Encumbrance, that now or in the future causes the Company not to have Defensible Title, as defined below.

(b) “Defensible Title,” means, as of the date of this Agreement and the Closing Date, other than Permitted Encumbrances, with respect to the Oil and Gas Properties, such record title and ownership by the Company that:

(i)

entitles the Company to receive and retain from such Oil and Gas Property, without reduction, suspension or termination, not less than the percentage set forth on Schedule 3.18(f)(i) as the Net Revenue Interest of all Hydrocarbons produced, saved and marketed from such Oil and Gas Property;

(ii)

obligates the Company to bear a percentage of the costs and expenses relating to the maintenance, development and operation of such Oil and Gas Property that is not more than the Working Interest set forth for such Oil and Gas Property on Schedule 3.18(f)(i) (unless such increase is accompanied by a proportionate increase in the Net Revenue Interest applicable to such Oil and Gas Property); and

Page 2

(iii)

is free and clear of all encumbrances except Permitted Encumbrances

6. Title Defect Amount; Environmental Defect Amount. “Title Defect Amount” or “Environmental Defect Amount” means, with respect to a Title Defect Property or Environmental Defect Property, as applicable, the reduction, in the Allocated Value (as set forth on Exhibit A-1, of a property as a result of the existence of one or more Title Defects or Environmental Defects, respectively, which amount will be determined as follows:

(a)

The Title Defect Amount with respect to a Title Defect Property will be determined by taking into consideration the Allocated Value of the Title Defect Property affected by such Title Defect (or if the Title Defect Property does not have a specific Allocated Value, then the Allocated Value thereof will be derived from the Allocated Value of the Oil and Gas Property associated therewith), the portion of the Title Defect Property subject to such Title Defect, and the legal effect of such Title Defect on the Title Defect Property affected thereby; provided, however, that:

(i)

if such Title Defect is in the nature of the Net Revenue Interest in an Oil and Gas Property being less than the Net Revenue Interest set forth on Schedule 3.18(f)(i) with respect thereto and the corresponding Working Interest remains the same, then the Title Defect Amount will be the Allocated Value for the relevant Oil and Gas Property multiplied by the percentage reduction in such Net Revenue Interest as a result of such Title Defect;

(ii)

if such Title Defect is in the nature of an encumbrance, then the Title Defect Amount will be the amount required to fully discharge such encumbrance; and

(iii)

if the Title Defect results from any matter not described in Paragraph (i) or Paragraph (ii) above, the Title Defect Amount will be an amount equal to the difference between the value of the Title Defect Property with such Title Defect and the value of such Title Defect Property without such Title Defect (taking into account the Allocated Value of the Title Defect Property). A Title Defect Amount may not exceed the Allocated Value of the Title Defect Property.

(b)

The Environmental Defect Amount with respect to an Environmental Defect Property will be determined by taking into consideration the Allocated Value of the Environmental Defect Property affected by such Environmental Defect (or if the Environmental Defect Property does not have a specific Allocated Value, then the Allocated Value thereof will be

Page 3

derived from the Allocated Value of the Oil and Gas Property associated therewith), the portion of the Environmental Defect Property subject to such Environmental Defect, and the decrease in value of such Environmental Defect Property resulting from such Environmental Defect, the amount of the civil penalty or fine assessed (or likely to be assessed) for such violation where the Environmental Defect is a violation of Environmental Law, or the cost to cure or otherwise remediate the Environmental Defect on such Environmental Defect Property, as applicable; provided the Environmental Defect Amount may not exceed the Allocated Value of the Environmental Defect Property.

7. Procedures for Title Defects and Environmental Defects.

(a)

If Seller and Buyer agree that a Title Defect or Environmental Defect exists and if prior to the Closing Date, Seller or the Company has been unable to cure such Title Defect or Environmental Defect (and there is no dispute as to whether or not it has been cured), and Buyer and Seller agree that Seller will not be able to cure such Title Defect or Environmental Defect within ninety (90) days after the Closing Date (the “Cure Period”), then the Initial Purchase Price will be reduced by the Title Defect Amount or Environmental Defect Amount, with respect to such Title Defect Property or Environmental Defect Property (taking into account the results of any curative efforts made by or on behalf of Seller with respect to such Title Defect Property or Environmental Defect Property).

(b)

If Seller and Buyer are unable to reach an agreement at any time as to (i) whether a Title Defect or Environmental Defect exists, or if it does exist whether it has been cured, or (ii) the amount of the Title Defect Amount or Environmental Defect Amount attributable to such Title Defect or Environmental Defect, then dispute resolution procedures pursuant to Section 8 may be initiated by Seller or Buyer promptly following the inability to reach an agreement. In such event, however and subject to Section 2.4 of the Agreement, then the Title Defect Property or Environmental Defect Property that is the subject of such dispute will not cause any reduction of the Initial Purchase Price.

(c)

Buyer will act in good faith and reasonably cooperate with Seller after the Closing to assist Seller in its cure of any Title Defects or Environmental Defects that have not been cured or resolved pursuant to Section 7(a). All reasonable third party costs incurred by Buyer in providing such assistance to Seller will be borne by Seller.

8. Arbitration.

(a)

If any Party hereto elects to submit any Title Defect or Environmental Defect dispute to arbitration as specifically provided in this Section 8, then such Party will notify the other Party in writing (“Arbitration Demand”).

Page 4

Within 15 days following such notice, Seller and Buyer agree to jointly select an arbitrator. For disputes regarding Title Defects or Title Defect Amounts, the arbitrator will be an experienced oil and gas attorney, familiar by training and experience with U.S. oil and gas legal and business matters including titles and oil and gas transactions. This Person will be the sole arbitrator (the “Title Defect Arbitrator”) to hear and decide all existing disputes regarding asserted Title Defects and Title Defect Amounts. For disputes regarding Environmental Defects or Environmental Defect Amounts, the arbitrator will be an experienced environmental attorney, familiar by training and experience with U.S. environmental legal and business matters in the oil and gas industry. This Person will be the sole arbitrator (the “Environmental Defect Arbitrator”) to hear and decide all existing disputes regarding asserted Environmental Defects and Environmental Defect Amounts. If Seller and Buyer are unable to agree on the Title Defect Arbitrator or Environmental Defect Arbitrator within the 15 day period, any Party hereto must apply exclusively to a Texas court for the selection of an Arbitrator or Environmental Defect Arbitrator, respectively with the qualifications set forth in this paragraph or other interim relief necessary to protect the value of the Oil and Gas Properties and/or the Properties, as the case may be.

(b)

Any arbitration hearing, if one is desired by the Title Defect Arbitrator or Environmental Defect Arbitrator, must be held in Dallas, Texas unless the Parties agree in writing to another location that is acceptable to both Parties and the Title Defect Arbitrator or Environmental Defect Arbitrator. The Parties agree that the laws of the State of Texas (exclusive of conflict of laws principles) shall govern the arbitration and the dispute regarding Title Defects or Environmental Defects. To the extent not otherwise provided in this Section 8, the arbitration will be conducted in accordance with the Texas Rules of Civil Procedure. Seller may elect to conduct the proceeding by written submissions from Seller and Buyer with exhibits, including interrogatories, supplemented with appearances by Buyer and Seller as the Title Defect Arbitrator or Environmental Defect Arbitrator may desire. The arbitration proceeding, subject only to the terms hereof, will be conducted informally and expeditiously and in such a manner as to result in a good faith resolution as soon as reasonably possible under the circumstances. The decision of the Title Defect Arbitrator or Environmental Defect Arbitrator with respect to such remaining disputed matters will be reduced to a writing that states the arbitrator’s reasons for the decision and shall be binding on the Parties. Judgment upon the award(s) rendered by the Title Defect Arbitrator or Environmental Defect Arbitrator may be entered and execution had in any court of competent jurisdiction, or application may be made to such court for a judicial acceptance of the award and an order of enforcement. Seller and Buyer, respectively, will bear their own legal fees and other costs incurred in presenting their respective cases. The charges and expenses of the Title Defect Arbitrator or Environmental Defect Arbitrator will be shared equally by the Parties.

Page 5

(c)

The arbitration will commence as soon as possible after the Title Defect Arbitrator or Environmental Defect Arbitrator is selected in accordance with the provisions of this Section 8. In fulfilling his or her duties with respect to determining the amount of a Title Defect Amount or Environmental Defect Amount, the Title Defect Arbitrator or Environmental Defect Arbitrator, as applicable, may consider such matters as, in the opinion of the Title Defect Arbitrator or Environmental Defect Arbitrator, are necessary or helpful to make a proper valuation; however, the Title Defect Arbitrator or Environmental Defect Arbitrator will be bound by those factors set forth in Section 6(a) and Section 6(c), respectively. Furthermore, the Title Defect Arbitrator or Environmental Defect Arbitrator may consult with and engage disinterested third parties to advise the Title Defect Arbitrator or Environmental Defect Arbitrator including, without limitation, geologists, geophysicists, petroleum engineers, title and oil and gas lawyers, accountants and consultants, and the fees and expenses of such third parties will be considered to be charges and expenses of the Title Defect Arbitrator or Environmental Defect Arbitrator. The sole remedy in any arbitration award will be resolution of alleged Title Defects and Title Defect Amounts or Environmental Defects and Environmental Defect Amounts which will then be applied as provided in Section 9 and neither the Title Defect Arbitrator nor the Environmental Defect Arbitrator will award any other remedy, including, without limitation, equitable relief, actual damages, consequential, exemplary or punitive damages, attorneys’ fees or interest reflecting the time value of money.

(d)

Any replacement Title Defect Arbitrator or Environmental Defect Arbitrator, should one become necessary, will be selected in accordance with the procedure provided above for the initial selection of the Title Defect Arbitrator or Environmental Defect Arbitrator.

(e)

As to any determination of amounts owing under the terms of this Section 8, no lawsuit based on such claimed amounts owing will be instituted by either Buyer or Seller, other than to compel arbitration proceedings or enforce the award of the Title Defect Arbitrator or Environmental Defect Arbitrator.

(f)

All privileges under state and federal law, including attorney-client and work-product privileges, will be preserved and protected to the same extent that such privileges would be protected in a federal or state court proceeding applying state or federal law, as the case may be.

Page 6

9. Limitations of Title Defect Amounts and Environmental Defect Amounts. Notwithstanding anything to the contrary herein, (i) there will be no reduction of the Initial Purchase Price and no amount owing by Seller with respect to a Title Defect or an Environmental Defect unless the Title Defect Amount or Environmental Defect Amount, as the case may be, exceeds $25,000; (ii) there will be no reduction of the Initial Purchase Price and no amount owing by Seller unless and until the Title Defect Amounts and Environmental Defect Amounts exceed 1% of the Initial Purchase Price in the aggregate (the “Defect Basket”), in which event the Seller will be liable for all Title Defect Amounts and Environmental Defect Amounts in excess of the Defect Basket from the first dollar above the Defect Basket, and (iii) the maximum liability of Seller for all Title Defect Amounts and Environmental Defect Amounts, in the aggregate, including all amounts owing before, on or after the Closing, will be fifteen percent (15%) of the Initial Purchase Price. Buyer’s sole and exclusive remedy for the reduction in value of the Company’s title to an Oil and Gas Property resulting from the existence of a Title Defect or Environmental Defect will be as provided in this Exhibit A; provided however, that, pursuant to Section 9.1(d) of the Agreement, Buyer or Seller may terminate this Agreement if the aggregate of the agreed-upon Title Defect Amounts and Environmental Defect Amounts exceeds fifteen percent (15%) of the Initial Purchase Price.

10. [Reserved]

11. Replacement Leases. Seller may, with the prior written consent of Buyer (such consent to be given in the sole discretion of Buyer), acquire, at its sole cost and expense, any one or more oil, gas and/or mineral leases (each such lease being a “Replacement Lease”) and such Replacement Lease shall be deemed to cure any one or more Title Defects agreed by Seller and Buyer on a Net Mineral Acre by Net Mineral Acre basis and such Replacement Lease shall be deemed to be a part of the Oil and Gas Leases for purposes of this Agreement.
