Article X

Certain Accounting Adjustments

Section 10.1 Adjustments. Appropriate adjustments shall be made between Buyer and Seller so that (a) all expenses (including all drilling costs, all capital expenditures, and all overhead charges under applicable operating agreements, and all other overhead charges actually charged by third parties) which are incurred in the operation of the Properties on or after the Effective Date will be borne by Buyer, and all proceeds (net of applicable production, severance, and similar Taxes) from the sale of oil, gas and/or other minerals produced from the Oil and Gas Properties on or after the Effective Date will be received by Buyer, and (b) all expenses (including all drilling costs, all capital expenditures, and all overhead charges under applicable operating agreements, and all other overhead charges actually charged by third parties)which are incurred in the operation of the Properties before the Effective Date will be borne by Seller and all proceeds (net of applicable production, severance, and similar Taxes) from the sale of oil, gas and/or other minerals produced from the Oil and Gas Properties before the Effective Date will be received by Seller. It is agreed that, in making such adjustments, all oil and all other hydrocarbons which were produced from the Oil and Gas Properties and which were, on the Effective Date, stored in tanks located on the Oil and Gas Properties and above pipeline connections shall be deemed to have been produced before the Effective Date (it is recognized that such tanks may not have been gauged on the Effective Date for the purposes of this Agreement and that determination of the volume of such oil in storage will be based on the best available data, which may include estimates). For purposes of this Section 10.1, oil in storage will be valued at the weighted average price for oil produced from the Oil and Gas Properties during the month of October 2010 after deduction for trucking, transportation and other expenses associated with the sale of oil and condensate. Ad valorem personal property and similar Taxes attributable to the Properties assessed with respect to a period which begins before, and ends after, the Effective Date shall be prorated based on the number of days in such period which fall on each side of the Effective Date (with the day on which the Effective Date falls being counted in the period after the Effective Date); it being expressly understood and agreed by the parties that such ad valorem personal property and similar Taxes will be based on the January 1, 2010 assessed values of the Properties, as reflected in the tax statement xxxxxxxx rendered by the applicable Governmental Authorities to Buyer, as operator, in 2010. Without limiting the foregoing allocation of liability for ad valorem and similar Taxes, Buyer shall be responsible for the administrative function of sending payment for the ad valorem and similar Taxes on the Properties to the appropriate Governmental Authority and for the filing of any related Tax Returns. No consideration shall be given to the local, state or federal income Tax liabilities of any party. For the avoidance of doubt, (a) any advances made by Seller prior to Closing for the drilling of xxxxx or other operations on the Properties (the "Prepaid Amounts") and (b) any reimbursements, refunds, rebates, credits or adjustments received by Buyer at any time for severance taxes paid with respect to production from the Properties before the Effective Date or for any other expenses relating to the Properties which were charged to Seller,shall be subject to the foregoing adjustment provisions, and, in the case of the reimbursements, refunds, rebates, credits or adjustments referred to in clause (b) above, shall be credited to Seller.

Section 10.2 Closing and Post-Closing Accounting Settlements

(a) At or before Closing, the parties shall determine, based upon the best information reasonably available to them, the amount of the adjustments provided for in Section 10.1. If the amount of adjustments so determined which would result in a credit to Buyer exceed the amount of adjustments so determined which would result in a credit to Seller, Buyer shall receive a credit, for the amount of such excess, against the Purchase Price to be paid at Closing, and, if the converse is true, Buyer shall pay to Seller, at Closing (in addition to amounts otherwise then owed), the amount of such excess.

(b) Within 10 business days after Closing, the parties shall determine, based upon the best information reasonably available to them, the amount of the adjustments provided for in Section 10.1 with respect to the Prepaid Amounts (to the extent such adjustments have not already been taken into account pursuant to paragraph (a) above), and shall make any such adjustments by appropriate payments from Buyer to Seller. These adjustments and the appropriate payments from Buyer shall be determined (i) on an individual AFE-by-AFE basis and (ii) independently of adjustments provided for in Section 10.1 with respect to expenses other than those relating to Prepaid Amounts, which such other adjustments shall be made pursuant to paragraphs (c) and (d) below.

(c) On or before 45 days after Closing, Buyer and Seller shall review any additional information which may then be available pertaining to the adjustments provided for in Section 10.1, shall determine if any additional adjustments (whether the same be made to account for expenses or revenues not considered in making the adjustments made at Closing, or to correct errors made in such adjustments) should be made beyond those made at Closing, and shall make any such adjustments by appropriate payments from Seller to Buyer or from Buyer to Seller.

(d) Should any additional items which would be the subject of adjustments provided for in Section 10.1 above come to the attention of Buyer or Seller after such adjustments under paragraph (c) above are concluded, such adjustments shall be made by appropriate payments from Buyer to Seller or from Seller to Buyer.

(e) Buyer shall afford Seller and its representatives reasonable access to, and furnish Seller with copies of, all Buyer's books and records and other documents pertaining to the items which are or should be the subject of the adjustments provided for in Section 10.1 to enable Seller to verify all such adjustments.

Section 10.3 No Sales Taxes. No sales, transfer or similar Tax will be collected at Closing in connection with this transaction. If, however, this transaction is later deemed to be subject to sales, transfer or similar Tax, at any time, for any reason, Buyer shall be responsible for all sales, transfer or other similar Taxes (including related penalty, interest or legal costs) due by virtue of this transaction on the Properties transferred pursuant hereto (regardless of the person liable for such Taxes under applicable Law) and shall remit such Taxes at that time. Seller and Buyer agree to cooperate with each other in all reasonable respects in demonstrating that the requirements for any exemption from such Taxes have been met.

Article XI

Post Closing Obligations

Section 11.1 Indemnification Obligations

(b) Buyer shall, on the date of Closing, agree (and, upon delivery to Buyer of the Conveyance, shall be deemed to have agreed), subject to the limitations and procedures contained in this Section 11.1, and in Sections 11.2, 11.3, and 15.1, following the Closing, to remain responsible for and indemnify, defend and hold Seller (and for purposes of Article XI, its affiliates and its and their respective directors, officers, employees and attorneys, contractors, subcontractors, and agents) harmless from and against any and all claims, obligations, actions, liabilities, damages, costs, expenses (including, without limitation, court costs and consultants' and attorneys' fees), or losses (collectively, "Seller's Losses") arising out of, relating to or caused by (i) any misrepresentation or breach of any warranty, covenant or agreement of Buyer contained in this Agreement, (ii) the ownership or operation of the Properties after the Effective Date, or (iii) the condition of the Properties on, prior to or after the Effective Date (including, without limitation, all obligations to properly plug and abandon, or replug and re-abandon, xxxxx located on the Properties, to restore the surface of the Properties and to comply with, or to bring the Properties into compliance with, Applicable Environmental Laws, including conducting any remediation activities which may be required on or otherwise in connection with activities on the Properties), regardless of whether such condition or the events giving rise to such condition arose or occurred before or after the Effective Date. Notwithstanding anything to the contrary contained herein, Buyer shall not be obligated to indemnify or hold Seller harmless for any of Buyer's Losses.

(c) Nothing in paragraphs (a) and (b) above shall be construed as overriding the adjustment procedure provided for in Article X.

(d) Notwithstanding anything to the contrary in this Agreement, the termination of this Agreement under Article VIII, shall not relieve either party from liability for any willful or negligent failure to perform or observe in any material respect any of its agreements or covenants contained herein which are to be performed or observed at or prior to Closing. In the event this Agreement terminates under Article VIII because a party has willfully or negligently failed to perform or observe in any material respect any of its agreements or covenants contained herein which are to be performed at or prior to Closing, then the other party shall be entitled to all remedies available at law or in equity and shall be entitled to recover court costs and reasonable attorneys' fees in addition to any other relief to which such party may be entitled.

Section 11.2 Indemnification Procedures.

(a) If indemnification pursuant to Sections 11.1(a) or 11.1(b) is sought, the party seeking indemnification (the "Indemnitee") shall give written notice to the indemnifying party of an event giving rise to the obligation to indemnify, describing in reasonable detail the factual basis for such claim ("Indemnification Claim"), and, provided that the indemnifying party acknowledges that it is liable for the matters that gave rise to such Indemnification Claim, shall allow the indemnifying party to assume and conduct the defense of the claim or action and cooperate with the indemnifying party in the defense thereof, provided that the omission to give such notice to the indemnifying party shall not relieve the indemnifying party from any liability which it may have to the Indemnitee, except to the extent that the Indemnification Claim arises from a third party claim ("Third Party Claim") against Indemnitee and the indemnifying party proves it was materially prejudiced by the failure to give such notice.

(b) Within fifteen (15) business days ("Response Period") of receipt of an Indemnification Claim, the indemnifying party shall notify Indemnitee in writing whether or not it disputes that it is obligated to indemnify the Indemnitee as set forth in the Indemnification Claim. Further, if such Third Party Claim is undisputed by the indemnifying party, the indemnifying party shall have the right, within the Response Period, to assume and conduct the defense of the Third Party Claim with counsel reasonably satisfactory to the Indemnitee. The Indemnitee shall have the right to employ separate counsel to represent the Indemnitee if the Indemnitee is advised by counsel that an actual conflict of interest makes it advisable for the Indemnitee to be represented by separate counsel and the reasonable expenses and fees of such separate counsel shall be paid by the indemnifying party. The indemnifying party shall not control (but may participate at its own expense in the defense of), and the Indemnitee shall be entitled to have sole control over, the defense or settlement, compromise, admission or acknowledgment of any Third Party Claim (i) as to which the indemnifying party fails to assume the defense within the Response Period or (ii) to the extent the Third Party Claim seeks an order, injunction or other equitable relief against the Indemnitee which, if successful, would materially adversely affect the business, operations, assets, or financial condition of the Indemnitee

(c) The indemnifying party shall obtain the prior written approval of the Indemnitee, which approval shall not be unreasonably withheld, before making any settlement, compromise, admission, or acknowledgment of the validity of any Third Party Claim or any liability in respect thereof if, pursuant to or as a result of such settlement, compromise, admission, or acknowledgment, injunctive or other equitable relief would be imposed against the Indemnitee or if, in the opinion of the Indemnitee, such settlement, compromise, admission, or acknowledgment could have an adverse effect on its business, operations, assets or financial condition. No indemnifying party shall consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by each claimant or plaintiff to each Indemnitee of a full and unconditional release from all liability in respect of such Third Party Claim.

Section 11.3 Tax Treatment of Indemnity Payments. Seller and Buyer agree to treat any indemnity payment made pursuant to this Agreement as an adjustment to the Purchase Price for Tax purposes.

Section 11.4 Transfer of Files. Seller will use its best efforts to deliver to Buyer, within ten (10) days after the Closing, all of Seller's lease files, abstracts, and title opinions, production records, well files, accounting records (but not including general tax and general financial accounting records), seismic records and surveys, gravity maps, electric logs, and geological or geophysical data and records, which relate solely and exclusively to the Properties.

Article XV

Miscellaneous Matters

Section 15.1 Survival of Provisions. All representations and warranties of Seller or Buyer contained in this Agreement or in any certificate delivered at the Closing shall survive the Closing until the first anniversary of the Closing Date (the "Survival Period"). Any claim for indemnification with respect to such representations and warranties must be made prior to the expiration of the Survival Period. Notwithstanding the foregoing, the obligation of each party hereto to indemnify any other party hereto with respect to such representations and warranties shall continue after the expiration of the Survival Period, with respect to any matter of which the party seeking indemnity hereunder shall have given the other party written notice as provided herein prior to the expiration of the Survival Period.

Section 15.2 Further Assurances. This transaction constitutes an assignment of the Seller's interests in Oil and Gas Properties and all related property. Seller intended to convey each property described in Exhibit A even though Seller's interest in such oil, gas and other minerals may be incorrectly described in, or omitted from, such Exhibit A. In order to effectuate and provide Buyer with the benefits of the transactions contemplated hereby, after the Closing, Seller shall execute and deliver, and shall otherwise cause to be executed and delivered, from time to time, such further instruments, notices, division orders, transfer orders and other documents, and do such other and further acts and things, as may be reasonably necessary to more fully and effectively grant, convey and assign the Properties to Buyer including, solely at Buyer's request, the conveyance of agreements or contracts of type set forth in Section 2.1(d). Any additional properties conveyed pursuant to this Section 15.2 shall be deemed to be a Property for all purposes of this Agreement, including the indemnification, representation and warranty provisions contained herein.

Section 15.3 Binding Effect; Successors and Assigns. The Agreement shall be binding on the parties hereto and their respective successors and permitted assigns. Neither party shall have the right to assign its rights or obligations under this Agreement, without the prior written consent of the other party first having been obtained.

Section 15.4 Like-Kind Exchange. The Seller may structure all or a portion of the transaction contemplated in this Agreement relating to the Properties sold to the Buyer, as a like-kind exchange under Section 1031 of the Code in accordance with this Section 15.4 (Seller, if it so elects, herein called the "Electing Party"). Such transfer shall be effectuated by mutually acceptable instruments, including without limitation, an exchange agreement and related assignments and consents to assignment. If Electing Party elects to structure the transaction as a like-kind exchange, the Electing Party shall substitute a third party, qualified intermediary (the "Intermediary") as the Seller of all or a portion of the Properties. The Intermediary shall be designated in writing by the Electing Party prior to Closing. The Electing Party is and shall remain primarily liable for the full and timely performance of each and every one of the representations, warranties, indemnities, obligations, and undertakings ascribed to the Electing Party under this Agreement, notwithstanding its substitution of the Intermediary, and in the event of a breach by either Buyer, Seller, or the Intermediary, then Buyer or Seller may proceed directly against the other without the need to join the Intermediary as a party to any action. Neither party represents to the other party that any particular tax treatment will be given to the other party as a result of the Electing Party's election to structure the transaction as a like-kind exchange. Buyer shall not incur any additional costs expenses, fees, or liabilities as a result of or connected with expenses incurred in connection with the exercise of the rights under this Section 15.4. THE ELECTING PARTY SHALL PROTECT, INDEMNIFY, AND HOLD HARMLESS BUYER FROM ANY LIABILITY, DAMAGES, OR COSTS, INCLUDING REASONABLE ATTORNEYS' FEES, COURT COSTS, AND RELATED EXPENSES, THAT MAY ARISE IN CONNECTION WITH ITS SECTION 1031 EXCHANGE UNDER THIS SECTION.

Section 15.5 Imbalances. On the date of Closing (and, upon the delivery to Buyer of the Conveyances), Buyer shall succeed to the position of Seller with respect to all gas imbalances. As a result of such succession Buyer shall (i) be entitled to receive any and all benefits, including payments of proceeds of production in excess of amounts which it would otherwise be entitled to produce and receive by virtue of ownership of the Oil and Gas Properties, which Seller would have been entitled to receive by virtue of such positions and (ii) shall be obligated to suffer any detriments (whether the same be in the form of obligations to deliver production which would have otherwise been attributable to its ownership of the Oil and Gas Properties without receiving full payment therefor, or be in the form of the obligation to make payment in cash) which Seller would have been obligated to suffer by virtue of such positions.

Section 15.6 Expenses. Except as otherwise expressly provided in this Agreement, each party shall bear and pay all expenses incurred by it in connection with the transaction contemplated by this Agreement. Buyer shall be responsible for all Conveyance and lien release recording fees and related costs and expenses.

Section 15.7 Entire Agreement — Time of the Essence. This Agreement contains the entire understanding of the parties hereto with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations, and discussions among the parties with respect to such subject matter. Time is of the essence in this Agreement.

Section 15.8 Public Statements. Either party may make any public disclosure regarding the existence of this Agreement it believes in good faith is required by applicable law, by the rules and regulations of the Securities and Exchange Commission or by the rules of any national securities exchange; and, if so required, the disclosing Party shall provide the other Party with a copy of such press release prior to the publication of such press release. This provision shall not be construed so as to limit either party's disclosures of or about this Agreement to regulatory authorities or to other parties as may otherwise be required by law, when in the opinion of the party's counsel such disclosure is so required.

Section 15.9 Injunctive Relief. The parties hereto acknowledge and agree that irreparable damage would occur in the event any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Agreement, and shall be entitled to enforce specifically the provisions of this Agreement, in any court of the United States or any state thereof having jurisdiction, in addition to any other remedy to which the parties may be entitled under this Agreement or at law or in equity.

Section 15.10 Amendments. This Agreement may be amended, modified, supplemented, restated or discharged (and provisions hereof may be waived) only by an instrument in writing signed by the party against whom enforcement of the amendment, modification, supplement, restatement or discharge (or waiver) is sought.

Section 15.11 Governing Law and Venue. This Agreement shall be governed by and construed in accordance with the internal Laws of the State of Texas applicable to a contract executed and performed in such State, without giving effect to conflicts of laws principles requiring the application of the Laws of another State. EACH PARTY HERETO WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT. Each of the parties hereby (a) irrevocably submits to the exclusive jurisdiction of the state and federal courts of Dallas County, Texas, for the purposes of any suit, action or proceeding arising out of or relating to this Agreement, and (b) waives, and agrees not to assert in any such suit, action or proceeding, any claim that (i) it is not personally subject to the jurisdiction of such court or of any other court to which proceedings in such court may be appealed; (ii) such suit, action or proceeding is brought in an inconvenient forum; or (iii) the venue of such suit, action or proceeding is improper.

Section 15.12 Multiple Counterparts; Fax. This instrument may be executed in a number of identical counterparts, each of which for all purposes is to be deemed an original, and all of which constitute collectively, one instrument. It is not necessary that each party hereto execute the same counterpart so long as identical counterparts are executed by each such party hereto. This instrument may be validly executed and delivered by facsimile or other electronic transmission.

Section 15.13 Confidentiality. Provided the Closing has occurred, during the Survival Period, Seller shall keep all information related to the Properties in strict confidence and shall not disclose such information to any person, except (i) to its accountants, attorneys, and other representatives, (ii) as required by law or legal process or in connection with any legal proceeding, (iii) for information that was or becomes generally publicly available other than as a result of a disclosure by Seller in violation of this Agreement, (iv) for information that becomes available to Seller on a nonconfidential basis from a third party that to Seller's knowledge, is not bound by a similar duty of confidentiality (contractual, legal, fiduciary, or other), and (v) for press releases permitted under Section 15.8.

Section 15.14 No Waiver. The failure of either party to insist upon strict performance of any provision hereof shall not constitute a waiver of, or estoppel against asserting, the right to require such performance in the future, nor shall a waiver or estoppel in any one instance constitute a waiver or estoppel with respect to a later breach of a similar nature or otherwise.

IN WITNESS WHEREOF, this Agreement is executed by the parties hereto on the date set forth above.
