WHEREAS, Seller owns certain oil and gas properties and related assets; WHEREAS, Seller desires to sell to Buyer, and Buyer desires to purchase from Seller, such oil and gas properties and related assets upon the terms and subject to the conditions set forth herein; NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth, the parties hereto agree as follows: ARTICLE I. CERTAIN DEFINITIONS Section 1.1 Certain Defined Terms. Unless the context otherwise requires, the respective terms defined in Appendix A attached hereto and incorporated herein shall, when used herein, have the respective meanings therein specified, with each such definition to be equally applicable both to the singular and the plural forms of the term so defined. Section 1.2 References, Gender, Number. All references in this Agreement to an "Article," "Section," or "subsection" shall be to an Article, Section, or subsection of this Agreement, unless the context requires otherwise. Unless the context otherwise requires, the words "this Agreement," "hereof," "hereunder," "herein," "hereby," or words of similar import shall refer to this Agreement as whole and not to a particular Article, Section, subsection, clause or other subdivision hereof. Whenever the context requires, the words used herein shall include the masculine, feminine and neuter gender, and the singular and the plural. ARTICLE II. SALE AND PURCHASE Subject to the terms and conditions of this Agreement, Seller agrees to sell and convey to Buyer, and Buyer agrees to purchase from Seller, the Assets. ARTICLE III. CONSIDERATION AND PAYMENT Section 3.1 Consideration. The consideration for the sale and conveyance of the Assets to Buyer is $8,000,000.00, as adjusted in accordance with the terms of this Agreement (the "Purchase Price"). The "Adjusted Purchase Price" shall be the Purchase Price (I) as adjusted by the Initial Adjustment Amount determined pursuant to Section 3.3, (ii) as adjusted for Title Defects, if any, in accordance with Section 6.2, (iii) as may be adjusted for excluded Title Defect Properties, if any, in accordance with Section 6.5, (iv) as may be adjusted for undisclosed gas imbalances, if any, pursuant to Section 3.5, (v) as may be adjusted for payments of portions of the Purchase Price received by Seller from holder of Preference Right contemporaneously with Closing in accordance with and as contemplated by Section 7.2, and (vi) as may be adjusted on account of Retained Assets as contemplated by Section 7.3. Section 3.2 Payment. Contemporaneously with the execution of this Agreement, Buyer has deposited an amount equal to twenty percent (20%) of the Purchase Price with Seller as a deposit hereunder (the "Deposit"). At the Closing, Buyer shall wire transfer the Adjusted Purchase Price minus the Deposit in immediately available funds to Texas Commerce Bank, N.A., ABA No. 113000609 for the account of Seller, Account No. 001-01763374, or such other account specified by Seller to Buyer on or prior to the business day immediately preceding the Closing Date. Section 3.3 Adjustment Period Cash Flow. (a) The Purchase Price shall be increased or decreased, as the case may be, by an amount equal to the Net Cash Flow with respect to the Assets for the time period (the "Adjustment Period") beginning at the Effective Time and ending at 7:00 a.m. (local time) on the Closing Date. The Seller shall deliver to Buyer on or prior to the business day immediately preceding the Closing Date a statement (the "Adjustment Statement") setting forth the Seller's preliminary determination (the "Initial Adjustment Amount") of the Net Cash Flow. If the Initial Adjustment Amount shown on the Adjustment statement is a positive number, then the Purchase Price shall be increased by such amount. If the Initial Adjustment Amount shown on the Adjustment Statement is a negative number, then the Purchase Price shall be decreased by such amount. (b) The Adjustment Statement shall be based upon actual information available to the Seller at the time of its preparation and upon the Seller's good faith estimates and assumptions. There shall be attached to the Adjustment Statement such supporting documentation and other data as is reasonably necessary to provide a basis for the Net Cash Flow shown therein. (c) The "Net Cash Flow" shall be the algebraic sum of (i) a positive amount equal to the aggregate amount paid by Seller as Seller's share of the costs and expenses of exploration, maintenance, development, production and operation of the Assets incurred with respect to the Adjustment Period (including prepayments of any such costs or expenses), (ii) a positive amount equal to the sum of (A) all overhead charges paid by Seller to any operator of any of the Assets, and (B) with respect to any properties operated by Seller or any affiliate of Seller, the overhead charges payable to Seller or such affiliated operator on account of the Subject Interests in such properties under existing operating agreements or, if no overhead charge is applicable to a Subject Interest under an existing operating agreement, an overhead charge to such Subject Interest equal to the Average Drilling and Producing Well Rates in the area as indicated in the most recent Survey of Combined Fixed Rate Overhead Charges for Oil and Gas Producers conducted by Ernst & Young or the prevailing rate in the area if the foregoing survey is not available, and (iii) a negative amount equal to the aggregate gross proceeds received by Seller from the sale or disposition of oil, gas and other hydrocarbons produced from the Assets during the Adjustment Period or from the rental, sale, salvage or other disposition of any other Assets during the Adjustment Period. 2 Section 3.4 Post Closing Review. After the Closing, Seller shall review the Adjustment Statement and determine the actual Net Cash Flow. On or prior to the ninetieth day after the Closing Date, Seller shall present Buyer with a statement of the actual Net Cash Flow and such supporting documentation as is reasonably necessary to support the Net Cash Flow shown therein (the "Final Adjustment Statement"). Buyer will give representatives of Seller reasonable access to its premises and to its books and records for purposes of preparing the Final Adjustment Statement and will cause appropriate personnel of Buyer to assist Seller and Seller's representatives, at no cost to Seller, in the preparation of the Final Adjustment Statement. Seller will give representatives of Buyer reasonable access to its premises and to its books and records for purposes of reviewing the calculation of Net Cash Flow and will cause appropriate personnel of Seller to assist Buyer and its representatives, at no cost to Buyer, in verification of such calculation. The Final Adjustment Statement shall become final and binding on Seller and Buyer as to the Net Cash Flow ninety (90) days following the date the Final Adjustment Statement is received by Buyer, except to the extent that prior to the expiration of such ninety (90) day period Buyer shall deliver to Seller notice, as hereinafter required, of its disagreement with the contents of the Final Adjustment Statement. Such notice shall be in writing and set forth all of Buyer's disagreements with respect to any portion of the Final Adjustment Statement, together with Buyer's proposed changes thereto, and shall include an explanation in reasonable detail of, and such supporting documentation as is reasonably necessary to support, such changes. If Buyer has timely delivered such a notice of disagreement to Seller, then, upon written agreement between Buyer and Seller resolving all disagreements of Buyer set forth in such notice, the Final Adjustment Statement will become final and binding upon Buyer and Seller as to the Net Cash Flow. If the Final Adjustment Statement has not become final and binding by the one hundred twentieth (120th) day following its receipt by Buyer, then Buyer and Seller may submit any unresolved disagreements of Buyer set forth in such notice to final and binding arbitration in accordance with the Arbitration Procedures. Upon resolution of such unresolved disagreements of Buyer, the Final Adjustment Statement shall be final and binding upon Buyer and Seller as to the Net Cash Flow. Within three (3) business days after the Final Adjustment Statement becomes final and binding, Seller or Buyer, as appropriate, shall pay to the other party the amount, if any, by which the Net Cash Flow as shown in the Final Adjustment Statement is less than or exceeds the Initial Adjustment Amount. Section 3.5 Gas Imbalance Credits. The Purchase Price shall be (a) reduced by an amount equal to (1) Unscheduled (Negative) Imbalances multiplied by (2) $1.00 per Mcf and (b) increased by an amount equal to (1) Unscheduled (Positive) Imbalances multiplied by (2) $1.00 per Mcf. 3 ARTICLE IV.

Section 5.2 Confidential Information. Unless and until the Closing occurs, Buyer agrees to maintain all information made available to it pursuant to Section 5.1 confidential and to cause its officers, employees, representatives, consultants and advisors to maintain all information made available to them pursuant to Section 5.1 confidential. ARTICLE VI. TITLE ADJUSTMENTS. Section 6.1 No Warranty or Representation. Without limiting Buyer's right to adjust the Purchase Price by operation of Section 6.2 and except for the special warranty of title which is contained in the Conveyance, Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to Seller's title to any of the Assets and Buyer hereby acknowledges and agrees that Buyer's sole remedy for any defect of title, including any Title Defect, with respect to any of the Assets shall be pursuant to the procedures set forth in this Article VI, which remedies shall cease, and be deemed to be finally and conclusively satisfied, in all respects, upon the Closing. Furthermore, Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to the accuracy or completeness of the information, records and data now, heretofore or hereafter made available to Buyer in connection with this Agreement (including, without limitation, any description of the Assets, pricing assumptions, potential for production of oil, gas or other hydrocarbons from the Subject Interests or any other matters contained in or related to any other material furnished to Buyer by Seller or by Seller's agents or representatives). Section 6.2 Buyer's Title Review. (a) Buyer's Assertion of Title Defects. Prior to the expiration of the fourteen (14) day period commencing on the execution of this Agreement (the "Title Examination Period"), Buyer shall notify Seller in writing of any matters which, in Buyer's reasonable opinion, constitute Title Defects and which Buyer intends to assert as a Title Defect with respect to any portion of a Property Subdivision pursuant to this Article VI. For all purposes of this Agreement, Buyer shall be deemed to have waived any Title Defect which Buyer fails to assert as a Title Defect by written notice given to Seller on or before the expiration of the Title Examination Period. To be effective, Buyer's written notice of a Title Defect must include (i) a brief description of the matter constituting the asserted Title Defect, (ii) the claimed Title Defect Amount attributable thereto, and (iii) supporting documents reasonably necessary for 7 Seller (as well as any title attorney or examiner hired by Seller) to verify the existence of such asserted Title Defect. Buyer shall promptly furnish Seller with written notice of any Seller Title Credit which is discovered by any of Buyer's employees or representatives while conducting Buyer's title review, due diligence or investigation with respect to the Subject Interests and Property Subdivisions. (b) Purchase Price Allocations. A portion of the Purchase Price has been allocated to the various Subject Interests in Property Subdivisions in the manner and in accordance with the respective values set forth in the Property Schedule. If any adjustment is made to the Purchase Price pursuant to this Section 6.2, a corresponding adjustment shall be made to the portion of the Purchase Price allocated to the affected Property Subdivision in the Property Schedule. (c) Seller's Opportunity to Cure. Seller shall have until two (2) days prior to the Closing Date, at its cost and expense, if it so elects but without obligation, to cure all or a portion of such asserted Title Defects. Any asserted Title Defects which are waived by Buyer or cured within such time shall be deemed "Permitted Encumbrances" hereunder. If Seller within such time fails to cure any Title Defect of which Buyer has given timely written notice as required above and Buyer has not and does not waive same on or before the day immediately preceding the Closing Date, the Property Subdivision affected by such uncured and unwaived Title Defect shall be a "Title Defect Property". (d) Buyer's Title Adjustments. Subject to Section 6.5, as Buyer's sole and exclusive remedy with respect to Title Defects, Buyer shall be entitled to reduce the Purchase Price by the amount, if any, by which the aggregate amount of Title Defect Amounts with respect to all Title Defect Properties exceeds the sum of $400,000.00 (the "Title Defect Deductible") plus the aggregate amount of Seller Title Credits with respect to all Property Subdivisions. "Title Defect Amount" shall mean, with respect to a Title Defect Property, the amount by which the value of such Title Defect Property is impaired as a result of the existence of one or more Title Defects, which amount shall be determined as follows: (1) If the Title Defect results from Seller having a lesser Net Revenue Interest in such Title Defect Property than the Net Revenue Interest specified therefor in the Property Schedule, the Title Defect Amount shall be equal to the product obtained by multiplying the portion of the Purchase Price allocated to such Title Defect Property in the Property Schedule by a fraction, the numerator or which is the reduction in the Net Revenue Interest and the denominator of which is the Net Revenue Interest specified for such Title Defect Property in the Property Schedule. (2) If the Title Defect results from Seller having a greater Working Interest in a Title Defect Property than the Working Interest specified therefor in the Property Schedule, the Title Defect Amount shall be equal to the present value (discounted at 10% compounded annually) of the increase in the costs and expenses forecasted in Exhibit B hereto with respect to such Title Defect Property for the period from and after the Effective Time which is attributable to such increase in the Seller's Working Interest. 8 (3) If the Title Defect results from the existence of a lien, the Title Defect Amount shall be an amount sufficient to discharge such lien. (4) If the Title Defect results from any matter not described in paragraphs (1), (2) or (3) above, the Title Defect Amount shall be an amount equal to the difference between the value of the Title Defect Property affected by such Title Defect with such Title Defect and the value of such Title Defect Property without such Title Defect (taking into account the portion of the Purchase Price allocated in the Property Schedule to such Title Defect Property); provided, that if such Title Defect is reasonably susceptible of being cured, the Title Defect Amount shall be the reasonable cost and expense of curing such Title Defect, if less. (5) If a Title Defect is not effective or does not affect a Title Defect Property throughout the entire productive life of such Title Defect Property, such fact shall be taken into account in determining the Title Defect Amount. (6) The Title Defect Amount with respect to a Title Defect Property shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder. For example, but without limitation, if a lien affects more than one Title Defect Property or the curative work with respect to one Title Defect results (or is reasonably expected to result) in the curing of any other Title Defect affecting the same or another Title Defect Property, the amount necessary to discharge such lien or the cost and expense of such curative work shall only be included in the Title Defect Amount for one Title Defect Property and only once in such Title Defect Amount. (7) If a Title Defect affects only a portion of a Property Subdivision (as contrasted with an undivided interest in the entirety of such Property Subdivision) and a portion of the Purchase Price has not been allocated specifically to such portion of a Property Subdivision in the Property Schedule, then for purposes of computing the Title Defect Amount, the portion of the Purchase Price allocated to such Property Subdivision shall be further allocated among the portions of such Property Subdivision in the proportion that the portion of the Property Subdivision affected by such Title Defect bears to the entire Property Subdivision. (8) The Title Defect Amount attributable to a Title Defect Property or any portion thereof shall not exceed the portion of the Purchase Price allocated to such Title Defect Property or such portion in Section 6.2(b) and paragraph (7) above. For example, but without limitation, if the Seller does not own fifty percent (50%) of the Net Revenue Interest specified in the Property Schedule for a Title Defect Property and such unowned fifty percent (50%) interest is also burdened by a lien, the Title Defect Amount for such Title Defect Property shall not exceed the portion of the Purchase Price allocable to such fifty percent (50%) interest notwithstanding that it may be affected by multiple Title Defects. 9 (9) No Title Defect Amount shall be allowed on account of and to the extent that an increase in the Seller's Working Interest in a Property Subdivision has the effect of proportionately increasing the Seller's Net Revenue Interest in such Property Subdivision. (10) With respect to any Subject Interest in a Property Subdivision in which Buyer likewise owned an undivided interest at the Effective Time, no Title Defect Amount shall be allowed on account of a Title Defect affecting such Subject Interest that also affected Buyer's interest in such Property Subdivision at the Effective Time. Section 6.3 Determination of Title Defects. A portion of a Property Subdivision shall be deemed to have a "Title Defect" if any one or more of the following statements is untrue with respect to such portion of a Property Subdivision as of the Effective Time and as of the Closing Date: (a) The Seller has Defensible Title thereto. (b) All royalties, rentals, Pugh clause payments, shut-in gas payments and other payments due with respect to such portion of a Property Subdivision have been properly and timely paid, except for payments held in suspense for title or other reasons which are customary in the industry and which will not result in grounds for cancellation of the Seller's rights in such portion of a Property Subdivision. (c) The Seller is not in default under the material terms of any leases, farm-out agreements or other contracts or agreements respecting such portion of a Property Subdivision which could (1) prevent the Seller from receiving the proceeds of production attributable to the Seller's interest therein, or (2) result in cancellation of the Seller's interest therein. Section 6.4 Seller Title Credit. A "Seller Title Credit" shall mean, with respect to a Property Subdivision, the amount by which the value of such Property Subdivision is enhanced by virtue of (a) Seller having a greater Net Revenue Interest in such Property Subdivision than the Net Revenue specified therefor in the Property Schedule, or (b) Seller having a lesser Working Interest in such Property Subdivision than the Working Interest specified therefor in the Property Schedule, which amount shall be determined as follows: (1) If the Seller Title Credit results from Seller having a greater Net Revenue Interest in such Property Subdivision than the Net Revenue Interest specified therefor in the Property Schedule, the Seller Title Credit shall be equal to the product obtained by multiplying the portion of the Purchase Price allocated to such Property Subdivision in the Property Schedule by a fraction, the numerator of which is the increase in the Net Revenue Interest and the denominator of which is the Net Revenue Interest specified for such Property Subdivision in the Property Schedule. 10 (2) If the Seller Title Credit results from Seller having a lesser Working Interest in a Property Subdivision than the Working Interest specified therefor in the Property Schedule, the Seller Title Credit shall be equal to the present value (discounted at 10% compounded annually) of the decrease in the costs and expenses forecasted in Exhibit B hereto with respect to such Property Subdivision for the period from and after the Effective Time which is attributable to such decrease in Seller's Working Interest. (3) In determining the amount of Seller Title Credits, the principles and methodology set forth in paragraphs (5), (6) and (7) of Section 6.2(d) shall be applied, mutatis mutandis. (4) No Seller Title Credit shall be allowed on account of and to the extent that a decrease in Seller's Working Interest in a Property Subdivision has the effect of proportionately decreasing Seller's Net Revenue Property Interest in such Property Subdivision. The Title Defect Deductible shall be restored to the extent that any portion thereof is applied as a credit against a Title Defect Amount attributable to a Title Defect which is subsequently cured by Seller or determined not to constitute a Title Defect. Section 6.5 Exclusion of Defect Properties. On or before the Closing Date, Seller may elect to retain and exclude from the Assets to be conveyed to Seller by Buyer pursuant to the terms hereof any Title Defect Property so long as the Purchase Price is reduced by the portion of the Purchase Price allocated to such Title Defect Property in the Property Schedule. Upon such election by Seller, said Title Defect Property, together with a pro rata share of all incidental rights, oil, gas and other hydrocarbons and other assets attributable or appurtenant thereto, shall be retained by Seller and excluded from the Assets which are conveyed by Seller to Buyer pursuant to the Conveyance. Section 6.6 Deferred Claims and Disputes. In the event that Buyer and Seller have not agree upon one or more adjustments, credits or offsets claimed by Buyer or Seller pursuant to and in accordance with the requirements of this Article VI, any such claim (a "Deferred Adjustment Claim") shall be settled pursuant to this Section 6.6 and, except as provided in Sections 9.1(g) and 9.2(g), shall not prevent or delay Closing. With respect to each potential Deferred Adjustment Claim, Buyer and Seller shall deliver to the other a written notice describing each such potential Deferred Adjustment Claim, the amount in dispute and a statement setting forth the facts and circumstances that support such party's position with respect to such Deferred Adjustment Claim. At Closing the Purchase Price shall not be adjusted on account of, and, except as provided in Sections 9.1(e) and 9.2(e), no effect shall be given to, the Deferred Adjustment Claim. On or prior to the thirtieth (30th) consecutive calendar day following the Closing Date (the "Deferred Matters Date"), the Seller and Buyer shall attempt in good faith to reach agreement on the Deferred Adjustment Claims and, ultimately, to resolve by written agreement all disputes regarding the Deferred Adjustment Claims. Any Deferred Adjustment Claims which are not so 11 resolved on or before the Deferred Matters Date shall be submitted to final and binding arbitration in accordance with the Arbitration Procedures; provided, however, that the Seller may elect at any time to resolve the disputes relating to the Deferred Adjustment Claims by the payment to Buyer of the amount by which the Purchase Price would have been reduced at Closing on account of the Title Defects which constitute Deferred Adjustment Claims if same did not constitute Deferred Adjustment Claims. Notwithstanding anything herein provided to the contrary, including Section 6.2(c), Seller shall be entitled to cure any Title Defect which constitutes a Deferred Adjustment Claim at any time prior to the point in time when a final and binding written decision of the board of arbitrators is made with respect thereto in accordance with the Arbitration Procedures. The amount of any reduction in the Purchase Price to which Buyer becomes entitled under the final and binding written decision of the board of arbitrators shall be promptly refunded by Seller to Buyer. Section 6.7 No Duplication. Notwithstanding anything herein provided to the contrary, if a Title Defect results from a matter which could also result in the breach of any representation or warranty of Seller set forth in Section 4.1, then Buyer shall only be entitled to assert such matter as a Title Defect pursuant to this Article VI and shall be precluded from also asserting such matter as the basis of the breach of any such representation or warranty. ARTICLE VII. PREFERENCE RIGHTS AND CONSENTS Section 7.1 Compliance. To Seller's knowledge, all agreements containing a (i) Preference Right are set forth in Part I of Schedule 7.1 and (ii) Transfer Requirement are set forth in Part II of Schedule 7.1 (except such agreements with respect to which all Preference Rights and Transfer Requirements applicable to the sale contemplated by this Agreement have been complied with or waived). Prior to the Closing Date, Seller shall initiate all procedures required to comply with or obtain the waiver of all Preference Rights and Transfer Requirements set forth in Schedule 7.1 with respect to the transactions contemplated by this Agreement. Section 7.2 Effect of Preference Rights. If a third party who has been offered a Preference Property pursuant to Section 7.1 elects prior to Closing to purchase such Preference Property in accordance with the terms of such Preference Right, and Seller and Buyer receive written notice of such election prior to the Closing Date, such Preference Property will be eliminated from the Assets and the Purchase Price shall be reduced by the portion of the Purchase Price allocated to such Preference Property pursuant to the immediately following sentence. The portion of the Purchase Price to be allocated to any Asset or portion thereof affected by a Preference Right (a "Preference Property") shall be the portion of the Purchase Price allocated thereto in the Property Schedule. If a Preference Right affects only a portion of a Property Subdivision and a portion of the Purchase Price has not been allocated specifically to such portion of a Property Subdivision in the Property Schedule, then the portion of the Purchase Price to be allocated to such Preference Property shall be determined in the same manner as provided in Section 6.2(d)(7) when a Title Defect affects only a portion of a Property Subdivision. If a third party who has been offered a Preference Property or who has been requested to waive its Preference Right pursuant to Section 7.1 does not elect to purchase 12 such Preference Property or waive such Preference Right with respect to the transactions contemplated by this Agreement prior to the Closing Date, such Preference Property shall be conveyed to Buyer at Closing subject to such Preference Right, unless such Preference Property has been otherwise eliminated from the Assets in accordance with other provisions of this Agreement. If a third party elects to purchase a Preference Property subject to a Preference Right and Closing has already occurred with respect to such Preference Property, Buyer shall be obligated to convey said Preference Property to such third party and shall be entitled to the consideration for the sale of such Preference Property. Section 7.3 Transfer Requirements. If a Transfer Requirement applicable to the transactions contemplated by this Agreement is not obtained, complied with or otherwise satisfied prior to the Closing Date; then, unless otherwise mutually agreed by Seller and Buyer, any Asset or portion thereof affected by such Transfer Requirement (a "Retained Asset") shall be held back from the Assets to be transferred and conveyed to Buyer at Closing and the Purchase Price to be paid at Closing shall be reduced by the portion of the Purchase Price which would be allocated to such Retained Asset pursuant to Section 7.2 if such Retained Asset were a Preference Property. Any Retained Asset so held back at the initial Closing will be conveyed to Buyer within ten (10) days following the date on which Seller obtains, complies with or otherwise satisfies all Transfer Requirements with respect to such Retained Assets for a purchase price equal to the amount by which the Purchase Price was reduced on account of the holding back of such Retained Asset; provided, however, if all Transfer Requirements with respect to any Retained Asset so held back at the initial Closing are not obtained, complied with or otherwise satisfied within one hundred twenty (120) days following the Closing Date, then such Retained Asset shall be eliminated from the Assets and this Agreement unless Seller and Buyer mutually agreed to proceed with a closing on such Retained Asset in which case Buyer shall be deemed to have waived any objection with respect to non-compliance with such Transfer Requirements. In connection with any subsequent conveyance of a Retained Asset, appropriate adjustments in Net Cash Flow and proration of revenues and expenses will be made to account for any delayed Closing with respect to a Retained Asset.

(a) With respect to unresolved Deferred Adjustment Claims, on or before the Deferred Matters Date, Seller and Buyer shall each submit to the other the list of what such party considers to comprise the remaining unresolved Deferred Adjustment Claims. The two lists shall together comprise the "Disputed Issues" relating to Deferred Adjustment Claims which shall be resolved by the binding arbitration provided for herein. (b) If, pursuant to Section 3.4 of the Agreement, either Buyer or Seller elects to submit any Final Adjustment Statement disagreements to arbitration, such disagreements will also constitute "Disputed Issues" to be resolved by the binding arbitration provided for herein. 3. Seller and Buyer, each being duly authorized by all necessary corporate, partnership or other proceedings, if any are applicable, shall submit the Disputed Issues to binding arbitration by a board of arbitration to be selected by the following procedures. Notices hereunder shall be sufficient if sent in accordance with the terms of the Agreement. With respect to Disputed Issues involving Deferred Adjustment Claims, within five (5) days after the Deferred Matters Date, Seller shall by written notice name one arbitrator and Buyer shall by written notice name one arbitrator. With respect to Disputed Issues involving Final Adjustment Statement disagreements, within five (5) days after either Buyer or Seller provides the other party with written notice that such party desires to submit such Final Adjustment Statement disagreements to arbitration, Seller shall by written notice name one arbitrator and Buyer shall by written notice name one arbitrator. If a party fails to name an arbitrator, the other party shall by further written notice name the second arbitrator. The two arbitrators so appointed shall name the third arbitrator within ten (10) days after the selection of the second arbitrator. If they fail to do so, either arbitrator may request the judge of the United States District Court for the Southern District of Texas having greatest tenure; but not yet on retired or senior status, to appoint the third arbitrator. If that judge fails to do so within thirty (30) days, either party may request the judge of that court next senior to name the third arbitrator, and if that judge fails to do so after ten (10) days, either party may make the request of the judge of that court next senior, and so on, until the board of arbitration is constituted. With respect to Disputed Issues involving Deferred Adjustment Claims, each of the arbitrators shall be knowledgeable about matters affecting title to oil and gas properties in the state or other jurisdiction in which Page - 1 - of Exhibit A-1 such properties are located, by virtue of managerial, land property administration, legal or judicial experience. With respect to Disputed Issues involving Final Adjustment Statement disagreements, each of the arbitrators shall be knowledgeable about oil and gas related accounting matters. In addition, the third arbitrator, in each case, shall be required to meet the qualification requirements of the Commercial Arbitration Rules of the American Arbitration Association (the "AAA Rules"), whether appointed by the arbitrators or by a judge as provided above. 4. If prior to rendering a decision an arbitrator resigns or becomes unable to serve, the arbitrator shall be replaced as follows. If that arbitrator was one of the two arbitrators appointed by the parties, the party that names him or her shall name a replacement; provided, however, that if that replacement is not named within five (5) days from notice of resignation or inability to serve, the other party shall name a replacement. If he or she was the third arbitrator, the other two arbitrators shall name a replacement; provided, however, that if they fail to agree on a replacement within ten (10) days, either arbitrator may follow the procedures specified in Paragraph 3 above and request judicial appoint of the replacement. 5. No party subject to these Arbitration Procedures will commence or prosecute any suit or action against another party subject to these Arbitration Procedures relating to the Disputed Issues, other than as may be necessary to compel arbitration under these Arbitration Procedures or to enforce the award of the board of arbitration. 6. The board of arbitration may in all matters act through a majority of its members on each matter if unanimity is not attained. It shall not be necessary that the same majority agree on each and every item; that is, the parties will be bound by majority rulings on each Disputed Issue even though the majority is not the same as to each Disputed Issue. In fulfilling their duties hereunder with respect to Deferred Adjustment Claims, each of the arbitrators shall be bound by the matters set forth in Article VI of the Agreement. The arbitrators shall not add any interest factor reflecting the time value of money to any title Defect Amount. 7. No matters whatsoever, other than the Disputed Issues, are subject to the agreement to arbitrate embodied in these Arbitration Procedures. The board of arbitration shall be empowered hereunder solely to resolve the Disputed Issues. The board of arbitration shall not have any authority to award punitive damages. The sole forum for the arbitration shall be Harris County, Texas and all hearings shall be conducted in Harris County, Texas. 8. The decision of the board of arbitration shall be rendered in writing and shall be final and binding upon the parties as to the Disputed Issues. The expenses of arbitration, including reasonable compensation to the third arbitrator, shall be borne equally by the parties. Each party shall bear the compensation and expenses of its own counsel, witnesses and employees and of any arbitrator it has appointed. If the Page - 2 - of Exhibit A-1 testimony of a witness is obtained by both parties, the costs associated with obtaining such testimony shall be borne equally between the parties. 9. Matters not specifically provided for in the Arbitration Procedures shall be governed by the AAA Rules. Page - 3 - of Exhibit A-1
