(a) If the Closing occurs, appropriate adjustments shall be made between Buyer and Seller so that (i) Buyer will receive all proceeds from sales of Minerals that are produced and saved from and after the Effective Date and any other revenues arising out of the ownership or operation of the Assets from and after the Effective Date, net of all applicable production, severance, and similar taxes, and (ii) Seller will receive all proceeds from sales of Minerals that are produced and saved prior to the Effective Date and any other revenues arising out of the ownership or operation of the Assets prior to the Effective Date.

(b) Not later than three business days prior to the Closing Date, Seller shall prepare and deliver to Buyer a statement of the estimated Purchase Price Adjustments taking into account the foregoing principles (the “Statement”). If approved by Buyer, at Closing, Buyer shall pay the Purchase Price, as adjusted by the estimated Purchase Price Adjustments reflected on the Statement. If not approved by Buyer, then the Statement shall be revised to make one-half (1/2) of the monetary changes to the Statement requested by Buyer, and, as so revised, shall be utilized to determine the adjusted Purchase Price paid by Buyer at Closing.

Section 10.04 Post-Closing Adjustments to Purchase Price.

(a) On or before 120 days after the Closing Date, Seller shall prepare and deliver to Buyer a revised Statement setting forth the actual Purchase Price Adjustments. To the extent reasonably required by Seller, Buyer shall assist in the preparation of the revised Statement. Each Party shall provide the other Party such data and information as the other Party may reasonably request supporting the amounts reflected on the revised Statement in order to permit the requesting Party to perform or cause to be performed an audit. The revised Statement shall become final and binding upon the parties on the 30th day following receipt thereof by Buyer (the “Final Settlement Date”) unless Buyer gives written notice of its disagreement (a “Notice of Disagreement”) to Seller prior to such date. Any Notice of Disagreement shall specify in detail the dollar amount, nature and basis of any disagreement so asserted. If a Notice of Disagreement is received by Seller in a timely manner, then the Parties shall resolve the Dispute evidenced by the Notice of Disagreement in accordance with Article XIV. Any revenues received by either Party after the Closing to which the other Party is entitled under this Agreement shall be promptly paid to the Party, which is entitled to receive such revenue, and such payment shall be taken into account in reaching the Final Statement. Any invoices received by either Party after the Closing shall be promptly forwarded to the Party, which is obligated to pay such invoice, and such obligated Party shall pay such invoice, unless disputed in good faith, on or before the date such invoice is due and such payment shall be taken into account in reaching the Final Statement.

(b) If the amount of the Purchase Price as set forth on the Final Statement exceeds the amount of the estimated Purchase Price paid at Closing, then Buyer shall pay to Seller the amount by which the Purchase Price as set forth on the Final Statement exceeds the amount of the estimated Purchase Price paid at Closing within five business days after the Final Settlement Date, together with interest at the Interest Rate as accrued from the Closing Date until the date of payment. If the amount of the Purchase Price as set forth on the Final Statement is less than the amount of the estimated Purchase Price paid at Closing, then Seller shall pay to Buyer the amount by which the Purchase Price as set forth on the Final Statement is less than the amount of the estimated Purchase Price paid at Closing within five business days after the Final Settlement Date, together with interest at the Interest Rate as accrued from the Closing Date until the date of payment. For purposes of this Agreement, the term “Final Statement” shall mean (i) if the revised Statement becomes final pursuant to Section 10.04(a), such revised Statement or (ii) upon resolution of any Dispute regarding a Notice of Disagreement, the revised Statement reflecting such resolutions, which the Parties shall issue, or cause the Independent Expert or arbitrators to issue, as applicable, following such resolution.

Section 10.05 Transfer Taxes. All sales, use or other taxes (other than taxes on gross income, net income or gross receipts) and duties, levies or other governmental charges (including recording or similar fees and expenses) incurred by or imposed with respect to the property transfers undertaken pursuant to this Agreement shall be the responsibility of, and shall be paid by, Buyer.

Section 10.06 Ad Valorem and Similar Taxes. Ad valorem taxes and all similar taxes assessed for period prior to the Effective Date shall be borne by Seller and ad valorem taxes and all similar taxes assessed for periods on or after the Effective Date, including prepaid taxes by Seller, shall be borne by Buyer. It is agreed that, in making such adjustments ad valorem taxes and all similar taxes assessed with respect to a period which the Effective Date splits 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 before the Effective Date).

Section 10.07 Actions of Seller at Closing. At the Closing, Seller shall:

(a) execute, acknowledge and deliver to Buyer the Deeds and such other conveyances, assignments, transfers, bills of sale and other instruments as may be necessary or desirable to convey the Assets to Buyer;

(b) execute, acknowledge and deliver to Buyer letters in lieu of transfer in the form attached hereto as Exhibit 10.07(b) or division orders directing all Buyers of production from the Mineral Interests to make payment of proceeds attributable to such production to Buyer from and after the Effective Time;

(d) execute and deliver to Buyer an affidavit attesting to Seller’s non-foreign status; and

(e) execute, acknowledge and deliver the Transition Services Agreement attached hereto as Exhibit 10.07 (e) and any other agreements provided for herein or necessary or desirable to effectuate the transactions contemplated hereby.

Section 10.08 Actions of Buyer at Closing. At the Closing, Buyer shall:

(a) deliver to Seller, the Purchase Price less the Deposit, as adjusted pursuant to the provisions hereof, but without any other deduction, by means of a completed federal funds transfer of same day funds to such bank accounts as may be designated by Seller;

(b) take possession of the Assets; and

(c) execute, acknowledge and deliver the Transition Services Agreement attached hereto as Exhibit 10.07 (e) and any other agreements provided for herein or necessary or desirable to effectuate the transactions contemplated hereby.

Section 10.09 Further Cooperation. After the Closing Date, each Party at the request of the other and without additional consideration, shall execute and deliver, or shall cause to be executed and delivered from time to time such further instruments of conveyance and transfer and shall take such other action as the other Party may reasonably request to convey and deliver the Assets to Buyer and to accomplish the orderly transfer of the Assets to Buyer in the manner contemplated by this Agreement. After the Closing, the Parties will cooperate to have all proceeds received attributable to the Assets to be paid to the proper Party hereunder within fifteen (15) days of receipt and to have all expenditures to be made with respect to the Assets to be made by the proper Party hereunder within fifteen (15) days of receipt. Furthermore, without limitation of the foregoing, it is expressly understood that the Assets are to include all the interests and properties from which the net revenue interests shown on Exhibit 5.11 were derived; and if it should be discovered, from time to time, that such interests and properties were not granted, conveyed, and assigned to Buyer at the Closing, Seller shall execute and deliver, and shall otherwise cause to be executed and delivered, from time to time, such further documents and do such further act and things as may be reasonably necessary to fully and effectively grant, convey and assign the such interests and properties to Buyer. From and after the Closing, Seller shall provide Buyer access to Seller’s and their respective affiliates’ personnel, books and records to the extent reasonably necessary to enable the Buyer to prepare the consolidated financial statements of the Buyer and its subsidiaries in such form and covering such periods as may be determined necessary by Buyer in its sole judgment. Seller shall use commercially reasonable efforts to cause the independent public accounts of each Seller to provide any consent necessary to the filing of such financial statements with the Securities and Exchange Commission, if desired by Buyer, and to provide such customary representation letters as are necessary in connection therewith.

It is understood that some of the individual conveyances executed and delivered at Closing may have descriptions that do not satisfy the statute of frauds or that are not acceptable for recording in specific states or jurisdictions. Furthermore, certain of the Assets may be presently held by subsidiaries or affiliates of Seller that are no longer in existence. Without limitation of the other more general further assurances contained in this Agreement, in any such event, it is expressly understood that on or before one hundred twenty (120) days after Closing Seller shall prepare, execute and deliver, or cause to be prepared, executed and delivered to Buyer, such conveyances as are reasonably necessary to convey all the Assets to Buyer, in each state or jurisdiction in which they are located, by conveyances that contain full and complete descriptions of the Assets to be conveyed (where such descriptions are available) to the reasonable satisfaction of Buyer. Such Seller also forever waives and releases any claim, demand, defense or cause or action that Seller may have against Buyer arising out of or in connection with any argument that any conveyance delivered pursuant to this Agreement does not contain a description that satisfies the statute of frauds or is not acceptable for recording.

Section 10.10 Confidentiality Agreement. If the Closing occurs, the binding portion of any confidentiality agreement executed by and among Seller and Buyer (the “Confidentiality Agreement”) shall terminate and be of no further force or effect insofar as the Confidentiality Agreement relates to the Assets.

Section 10.11 Documents and Geophysical/Geological Data. If the Closing occurs, within thirty (30) business days thereafter, Seller shall deliver to Buyer in Houston Texas, the originals of (i) all land, title, contract and division of interest files, plat books and all other pertinent files of Seller relating to the Assets (collectively “Documents”) and (ii) insofar and insofar only as Seller has the right to do so, any seismic data, geological or geophysical data, or other similar data, or any interpretations thereof or other data or records related to the Assets. Buyer hereby agrees to retain the originals of all Documents for at least a period of six (6) years following the Closing Date and to give Seller and its designees reasonable access to such originals of the Documents as may be necessary for Seller to comply with any legal proceedings or any inquiries, audits, or the like by any governmental entity, and to prepare financial statements. Additionally, after the Closing Date each Party at the request of the other shall provide reasonable access to records and files related to the Assets to the extent related to the period of ownership of Assets by the Party seeking such access.

Section 10.12 Imbalance Adjustments. At Closing, Buyer and Seller shall, based upon data available at that time, determine (i) the total amount of “overproduction” of gas as of the Effective Date with respect to the Assets (e.g. volumes of gas, measured in MMBtu, taken from such Assets by the Seller and its predecessors in title to the Assets in excess of those volumes which the ownership of the Assets would entitle them to receive) and (ii) total amount of “underproduction” of gas as of the Effective Date with respect to Assets (e.g. the amount by which the volumes of gas, measured in MMBtu, from such ▇▇▇▇▇ and units which the ownership of the Assets by Seller and its predecessors in title thereto would entitle them to take exceeds the volumes taken from the Assets by Seller and such predecessors). If the total amount of overproduction (as so determined) exceeds the total amount of underproduction (as so determined), then the Purchase Price shall be decreased by an amount equal to $2.50 per MMBtu times such excess. If the total amount of underproduction (as so determined) exceeds the total amount of overproduction (as so determined), then the Purchase Price shall be increased by an amount equal to $2.50 per MMBtu times such excess.

ARTICLE XI.

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

Section 11.02 Effect of Termination. In the event that Closing does not occur as a result of any Party exercising its right to terminate pursuant to Section 11.01, the Deposit shall be refunded to Buyer and no Party shall have any further rights or obligations under this Agreement, except that nothing herein shall relieve any Party from any liability for any breach hereof or any liability that has accrued prior to the date of such termination.

ARTICLE XI

Assumption and Indemnification

Section 12.01 Indemnification by Buyer.

ARTICLE XIII.

Limitations on Representations and Warranties

Section 13.01 Disclaimers of Representations and Warranties.

Notwithstanding anything contained in this Agreement to the contrary:

(i) Buyer accepts responsibility for and agrees to pay any and all costs and expenses associated with assessment, remediation, removal, transportation and disposal of asbestos and NORM associated with the Assets, and may not claim the fact that assessment, remediation, removal, transportation or disposal of asbestos and NORM are not complete or that additional costs and expenses are required in connection with assessment, remediation, removal, transportation or disposal of asbestos and NORM as an Environmental Condition or a breach of Seller’s representations and warranties under this Agreement or the basis for any other redress against Seller; and Buyer irrevocably waives any and all claims against Seller associated with the same; and

(ii) Buyer releases Seller from and shall fully protect, defend, indemnify, and hold Seller harmless from and against any and all Claims relating to, arising out of, or connected with, directly or indirectly, the assessment, remediation, removal, transportation and disposal of asbestos and NORM associated with the Assets, no matter whether arising before or after the Effective Time.

Section 14.02 Senior Management. If a Dispute occurs that the senior representatives of the Parties responsible for the transactions contemplated by this Agreement have been unable to settle or agree upon within a period of 15 days after such Dispute arose, Seller shall nominate and commit one of its senior officers, and Buyer shall nominate and commit one of its senior officers, to meet at a mutually agreed time and place not later than 30 days after the Dispute has arisen to attempt to resolve same.

The foregoing notwithstanding, in all events any pre-closing arbitration shall be concluded, and a final decision rendered at least five (5) days prior to the Closing Date.

(g) Waiver of Certain Damages. Notwithstanding any other provision in this Agreement to the contrary, the Parties expressly agree that the arbitrators shall have absolutely no authority to award consequential, incidental, special, treble, exemplary or punitive damages of any type under any circumstances regardless of whether such damages may be available under Texas law, or any other laws, or under the Federal Arbitration Act or the Rules.

The Parties shall request that final decision of the arbitrators be in writing, be as brief as possible, set forth the reasons for such final decision, and if the arbitrators award monetary damages to either Party, contain a certification by the arbitrators that, they have not included any consequential, incidental, special, treble, exemplary or punitive damages. To the fullest extent permitted by law, the arbitration proceeding and the arbitrators’ decision and award shall be maintained in confidence by the Parties and the Parties shall instruct the arbitrators to likewise maintain such matters in confidence.

ARTICLE XV

The receiving party shall have 48 hours after receipt of such notice within which to advise the sending party whether it consents to such publicity or release. The receiving party’s failure to notify the sending party of any objection to the proposed publicity or release within such period shall be conclusively presumed to be consent thereto.
