1.01 Contribution. As a contribution to Buyer and in consideration for the payment of the Purchase Price to the Sellers as described in Section 1.02, the Sellers shall contribute to Buyer at Closing all of the Seller Securities free and clear of all Liens (except as provided in Section 4.04).

1.02 Purchase Price. At the Closing, Buyer agrees to pay to the Sellers an aggregate cash and/or Buyer Units in an aggregate amount (the “Purchase Price”) equal to (i) $70,000,000.00, minus (ii) the Sellers’ Expenses, plus (iii) the amount, if any, by which Estimated Net Working Capital exceeds Target Working Capital, minus (iv) the amount, if any, by which Estimated Net Working Capital is less than the Target Working Capital, minus (v) the aggregate amount of Closing Indebtedness, minus (vi) the amount equal to one-half the premium for the Tax Insurance Policy (if the Sellers chose to reduce the Purchase Price instead of paying one-half of the premium directly). At Closing, five percent (5%) of the Purchase Price in the form of Buyer Units (the “Escrow Amount”) shall be deposited in the Escrow Account with the Escrow Agent pursuant to the terms and conditions of the Escrow Agreement.

ARTICLE II
CLOSING AND PURCHASE PRICE ADJUSTMENTS

2.01 The Closing. The closing of the transactions contemplated by this Agreement (the “Closing”) shall take place at the offices of Gardere ▇▇▇▇▇ ▇▇▇▇▇▇ LLP located at ▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇-▇▇▇▇ at 10:00 a.m. local time on July 31, 2007 or on such other date as is mutually agreeable to Buyer and the Sellers. The date and time of the Closing are referred to herein as the “Closing Date.”

2.02 The Closing Transactions. Subject to the terms and conditions set forth in this Agreement, the parties hereto shall consummate the following transactions on the Closing Date:

(a) the Sellers shall deliver to Buyer all of the certificates, if any, evidencing the Seller Securities, duly endorsed for transfer or accompanied by duly executed security transfer powers or other form of assignment and transfer;

(b) Buyer shall deliver to the Sellers the Purchase Price (excluding the Escrow

Amount and the amount required to repay Closing Indebtedness) in the following manner: (i) the cash portion shall be paid by wire transfer of immediately available funds to the account(s) designated by the Sellers at least three (3) business days prior to the Closing Date and (ii) the equity portion shall be paid in Buyer Units in the form of certificates evidencing such Buyer Units;

(c) Buyer shall repay, or cause to be repaid, on behalf of the Company and its Subsidiaries, the Closing Indebtedness by wire transfer of immediately available funds to the account(s) designated by the holders of such Closing Indebtedness at least three (3) business days prior to the Closing Date;

(d) Buyer shall deliver the Escrow Amount by wire transfer of immediately available funds to the Escrow Agent;

(e) the Sellers shall deliver to Buyer evidence satisfactory to Buyer that all Liens on the Seller Securities and/or the Company’s assets securing Indebtedness (other than Permitted Liens) shall be released upon the payment of the Closing Indebtedness in full on terms and conditions reasonably acceptable to the Sellers, Buyer and the holders of such Liens;

(f) the Sellers shall have paid or assumed all of the Sellers’ Expenses as set forth in Section 11.02; and

(g) Buyer and the Sellers shall make such other deliveries as are required by Article III hereof.

2.03 Net Working Capital.

(a) At least three (3) business days prior to the Closing Date, the Sellers shall deliver to Buyer its good faith calculation of Estimated Net Working Capital, Closing Indebtedness and the Purchase Price. The Sellers and Buyer shall negotiate in good faith to resolve any disagreement with respect to the Estimated Net Working Capital, Closing Indebtedness and the Purchase Price prior to the Closing. The Estimated Net Working Capital shall be determined in accordance with GAAP and consistent with the methodology set forth on Exhibit C attached hereto.

(b) As promptly as possible, but in any event within ninety (90) days after the Closing Date, Buyer will deliver to the Sellers a balance sheet of the Company and its Subsidiaries (the “Closing Balance Sheet”) and a statement showing the calculation of Net Working Capital and its calculation of any adjustments pursuant to Section 2.03(c) below, derived from the Closing Balance Sheet (together with the Closing Balance Sheet, the “Preliminary Net Working Capital Statement”). The Closing Balance Sheet shall be prepared, and Net Working Capital shall be determined, each as of the Effective Time, on a consolidated basis in accordance with GAAP and with the same accounting methods, policies, principles, practices and procedures, with consistent classifications, judgments and estimations methodology, as were used in preparation of the audited consolidated balance sheet of the Company and its Subsidiaries as of the fiscal year ended December 31, 2006 (the “2006 Balance Sheet”). The Net Working Capital and the related Purchase Price adjustment shall be derived from the Closing Balance Sheet and determined in accordance with GAAP and consistent with the methodology set forth on Exhibit C

attached hereto. The parties agree that the purpose of preparing the Closing Balance Sheet and determining Net Working Capital and the related Purchase Price adjustment contemplated by Section 2.03(c) is to measure changes in Net Working Capital, and such processes are not intended to permit the introduction of different judgments, accounting methods, policies, principles, practices, procedures, classifications or estimation methodologies for the purpose of preparing the Closing Balance Sheet or determining Net Working Capital. After delivery of the Preliminary Net Working Capital Statement, Buyer shall give the Sellers and its accountants reasonable access to review the Company’s and its Subsidiaries’ books and records and work papers related to the preparation of the Preliminary Net Working Capital Statement. The Sellers and their accountants may make reasonable inquires of Buyer, the Company and their respective accountants regarding questions concerning, or disagreements with, the Preliminary Net Working Capital Statement arising in the course of its review thereof, and Buyer shall use its, and shall cause the Company to use its, commercially reasonable efforts to cause any such accountants to cooperate with and respond to such reasonable inquiries. If the Sellers have any objections to the Preliminary Net Working Capital Statement, the Sellers shall deliver to Buyer a statement setting forth their objections thereto (an “Objections Statement”). If an Objections Statement is not delivered to Buyer within 30 days after delivery of the Preliminary Net Working Capital Statement, the Preliminary Net Working Capital Statement shall be final, binding and nonappealable by the parties hereto. The Sellers and Buyer shall negotiate in good faith to resolve any such objections, but if they do not reach a final resolution within 15 days after the delivery of the Objections Statement, the Sellers or Buyer may submit such dispute to PricewaterhouseCoopers LLP or a mutually acceptable qualified dispute resolution firm (the “Dispute Resolution Auditor”). Any further submissions to the Dispute Resolution Auditor must be written and delivered to each party to the dispute. The Dispute Resolution Auditor shall consider only those items and amounts which are identified in the Objections Statement as being items which the Sellers and Buyer are unable to resolve. The Dispute Resolution Auditor’s determination will be based on the definition of Net Working Capital contained herein. The Sellers and Buyer shall use their commercially reasonable efforts to cause the Dispute Resolution Auditor to resolve all disagreements as soon as practicable and in any event within 45 days after the submission of any dispute. Further, the Dispute Resolution Auditor’s determination shall be based solely on the presentations by Buyer and the Sellers (or their respective independent auditors or other agents) which are in accordance with the terms and procedures set forth in this Agreement (i.e., not on the basis of an independent review). The resolution of the dispute by the Dispute Resolution Auditor shall be final, binding and nonappealable on the parties hereto. The fees and expenses of the Dispute Resolution Auditor shall be allocated between and paid by Buyer and/or the Sellers based upon the percentage which the portion of the contested amount not awarded to each party bears to the amount actually contested by such party, as determined by the Dispute Resolution Auditor.

(c) If the Net Working Capital as finally determined pursuant to Section 2.03(b) above is greater than the Estimated Net Working Capital, Buyer shall promptly pay to the Sellers the amount of such excess in cash. If the Net Working Capital as finally determined pursuant to Section 2.03(b) above is less than the Estimated Net Working Capital, the Sellers shall promptly pay to Buyer in cash the amount of such shortfall. Payments to be made pursuant to this Section 2.03(b) shall be made in accordance with Section 2.04.

2.04 Post Closing Adjustment Payment. Any amounts payable pursuant to Section

2.03(c) above shall be paid promptly (but in any event within ten (10) business days) after such amounts are finally determined pursuant to Section 2.03(b) by wire transfer of immediately available funds to an account or accounts designated by the Sellers or Buyer, as applicable. In addition, if Buyer so elects in its sole discretion, Buyer may collect any amounts not paid by the Sellers pursuant to this Section 2.04 by making a claim against the Escrow Account.

2.05 Adjustment for Title Defects.

(a) General Disclaimer of Title Warranties and Representations. Except as set forth in Section 4.07(c), the Sellers and the Company make no warranty or representation, express, implied, statutory or otherwise, not even as to a return of the Purchase Price, with respect to title to any of the Oil and Gas Interests and Buyer hereby acknowledges and agrees that, except for any remedy Buyer may have for the breach of Section 4.07(c), which shall be in addition to any remedy set forth in this Section 2.05, Buyer’s sole remedy for any defect of title, including any Title Defect, with respect to any of the Oil and Gas Interests shall be as set forth in Section 2.05(b).

(b) Notice of Title Defects; Defect Adjustments.

(i) Title Defect Notices. On or before ten (10) days prior to Closing (the “Title Claim Date”), Buyer must deliver claim notices to Company meeting the requirements of this Section 2.05(b) (a “Title Defect Notice”) setting forth any matters which, in Buyer’s reasonable opinion, constitute Title Defects and which Buyer intends to assert as a Title Defect pursuant to this Section 2.05. Except for a breach of Section 4.07(c), which shall not be limited by this sentence, Buyer shall be deemed to have waived, and the Sellers and the Company shall have no liability for, any Title Defect which Buyer fails to assert as a Title Defect by a Title Defect Notice received by Company on or before the Title Claim Date. To be effective, each Title Defect Notice shall be in writing, and shall include (A) a description of the alleged Title Defect(s), (B) the Well(s) (and the applicable zone(s) therein) and/or other Oil and Gas Interests affected by the Title Defect (each a “Title Defect Property”), (C) the Allocated Value of each Title Defect Property, (D) supporting documents reasonably necessary for the Sellers to verify the existence of the alleged Title Defect(s), and (E) the amount by which Buyer reasonably believes the Allocated Value of each Title Defect Property is reduced by the alleged Title Defect(s) and the computations upon which Buyer’s belief is based.

(ii) Title Benefit Notices. The Sellers shall have the right, but not the obligation, to deliver to Buyer on or before the Title Claim Date a notice (a “Title Benefit Notice”) with respect to each Title Benefit, which Title Benefit Notice must be delivered by the Company or the Sellers, as the case may be, to the Buyer on or before the Title Claim Date. To be effective, each Title Benefit Notice shall be in writing, and shall include (A) a description of the alleged Title Benefit(s), (B) the Well(s) (and the applicable zone(s) therein) and/or other Oil and Gas Interests affected by the Title Benefit (each a “Title Benefit Property”), (C) the Allocated Value of each Title Benefit Property, (D) supporting documents reasonably necessary for the Buyers to verify the existence of the alleged Title Benefit(s), and (E) the amount by which Seller reasonably believes the Allocated Value of each Title Benefit Property is increased by the alleged Title Benefit(s)

and the computations upon which Seller’s belief is based. The Sellers shall be deemed to have waived all Title Benefits which Sellers fail to assert as a Title Benefit by a Title Benefit Notice received by the Buyer on or before the Title Claim Date.

(iii) Sellers’ Right to Cure. The Sellers shall have the right, but not the obligation, to attempt, at their sole cost, to cure at any time prior to the Closing Date (the “Cure Period”), any Title Defects of which Company has been advised by Buyer.

(iv) Remedies for Title Defects. Subject to the Sellers’ continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto in accordance with this Section 2.05(b), in the event that any Title Defect timely asserted by Buyer in accordance with Section 2.05(b)(i) is not waived in writing by Buyer or cured on or before Closing, the Sellers shall, at their sole option, elect to:

(A) subject to the Individual Title Defect Threshold and the Aggregate Deductible, reduce the Purchase Price by an amount (“Title Defect Amount”) determined pursuant to Section 2.05(b)(vii) or 2.05(b)(x) as being the value of such Title Defect;

(B) retain the entirety of the Oil and Gas Interest that is subject to such Title Defect, together with all associated Oil and Gas Interests, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such asset and such associated Oil and Gas Interests; or

(v) Remedies for Title Benefits. With respect to each Well (or specified zone(s) therein) affected by Title Benefits reported under Section 2.05(b)(ii), the Purchase Price shall be increased by an amount (the “Title Benefit Amount”) equal to the increase in the Allocated Value for such Well caused by such Title Benefits, as determined pursuant to Section 2.05(b)(viii) or 2.05(b)(x). Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided to the Sellers for any individual Title Benefit for which the Title Benefit Amount does not exceed $25,000 (the “Individual Title Benefit Threshold”); and (ii) in no event shall there be any adjustments to the Purchase Price or other remedies provided to the Sellers for any Title Benefit that exceeds the Individual Title Benefit Threshold unless the sum of the Title Benefit Amounts of all such Title Benefits that exceed the Individual Title Benefit Threshold, in the aggregate, exceeds the Aggregate Deductible, after which point the Sellers shall be entitled to adjustments to the Purchase Price only with respect to such Title Benefits in excess of such Aggregate Deductible.

(vi) Exclusive Remedy. Except for any remedy Buyer may have for the breach of Section 4.07(c), which remedy shall be in addition to the remedy provided under this section, Section 2.05(b)(iv) shall be the exclusive right and remedy of Buyer with respect to the Company’s failure to have Defensible Title with respect to any Oil and Gas Interest.

(vii) Title Defect Amount. The Title Defect Amount resulting from a Title

Defect shall be the amount by which the Allocated Value of the affected Title Defect Property is reduced as a result of the existence of such Title Defect and shall be determined in accordance with the following terms and conditions:

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

(B) if the Title Defect is a Lien that is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Defect Property;

(C) if the Title Defect does not affect the ratio of the Net Revenue Interest to the Working Interest for any Title Defect Property stated in Schedule B, then the Title Defect Amount shall be the product of the Allocated Value of such Title Defect Property multiplied by a fraction, the numerator of which is the decimal amount of the Net Revenue Interest decrease and the denominator of which is the Net Revenue Interest stated in Schedule B;

(D) if the Title Defect represents an obligation or Lien upon or other defect in title to the Title Defect Property of a type not described above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property, the values placed upon the Title Defect by Buyer and the Sellers and such other reasonable factors as are necessary to make a proper evaluation; provided, however, that if such Title Defect is reasonably capable of being cured, the Title Defect Amount shall not be greater than the reasonable cost and expense of curing such Title Defect;

(E) If (a) a Title Defect Property is not a Well (or specified zone(s) therein), (b) such Title Defect Property does not have an Allocated Value, (c) the Title Defect with respect to such Title Defect Property causes a loss of title to such Title Defect Property, and (d) the loss of such title to such Title Defect Property will prevent the continued operation or production of a Well (or one or more specified zone(s) therein) shown in Schedule B (such Well or the specified zone(s) therein being referred to as the “Affected Well”) and the other Oil and Gas Interests are not capable of providing an alternative means to support, in all material respects, the continued operation or production of the Affected Well, then such Title Defect Property (a “Defective Support Property”) and such Affected Well(s) shall collectively be considered a single Title Defect Property for purposes of this Section 2.05; provided, however, that the Title Defect Amount resulting from the Title Defect affecting such Defective Support Property shall be the lesser of (1) the reasonable cost to replace such Defective Support Property, if such Defective Support Property is reasonably capable of being replaced, (2) the reasonable cost of providing an alternative means to support in all material respects the continued operation or production of the Affected Well, or (3) the Title Defect Amount that would otherwise be applicable to such Title

Defect under this Section 2.05.

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

(G) notwithstanding anything to the contrary in this Section 2.05, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Value of the Title Defect Property.

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

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

(B) if the Title Benefit does not affect the ratio of the Net Revenue Interest to the Working Interest for any Title Benefit Property stated in Schedule B, then the Title Benefit Amount shall be the product of the Allocated Value of such Title Benefit Property multiplied by a fraction, the numerator of which is the decimal amount of the Net Revenue Interest increase and the denominator of which is the Net Revenue Interest stated in Schedule B; and

(C) if the Title Benefit represents a benefit in title of a type not described above, the Title Benefit Amount shall be determined by taking into account the Allocated Value of the affected property, the portion of the subject property affected by the Title Benefit, the legal effect of the Title Benefit, the potential economic effect of the Title Benefit over the life of the subject property, the values placed upon the Title Benefit by Buyer and the Sellers and such other reasonable factors as are necessary to make a proper evaluation.

(ix) Title Deductibles. Notwithstanding anything to the contrary, (A) in no event shall there be any adjustments to the Purchase Price or other remedies provided by the Sellers for any individual Title Defect for which the Title Defect Amount does not exceed $25,000 (“Individual Title Defect Threshold”); and (B) in no event shall there be any adjustments to the Purchase Price or other remedies provided by the Sellers for any Title Defect that exceeds the Individual Title Defect Threshold unless the sum of (1) the Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold, in the aggregate, excluding any Title Defects cured by the Sellers plus (2) the Remediation Amounts of all environmental defects, in the aggregate, excluding any individual Environmental Condition for which the Remediation Amount does not exceed the Individual Environmental Threshold and any environmental defects cured by the Sellers, exceeds the Aggregate Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price or other remedies only with respect to such Title Defects in excess of such Aggregate Deductible.

(x) Title Dispute Resolution. The Sellers and Buyer shall attempt to agree on all Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts prior to Closing. If the Sellers and Buyer are unable to agree by Closing, the Title Defect Amounts and Title Benefit Amounts in dispute shall be exclusively and finally resolved pursuant to this Section 2.05(b)(x). There shall be a single arbitrator, who shall be a title attorney with at least ten years experience in oil and gas titles involving properties in the regional area in which the Title Defect Properties are located, as selected by mutual agreement of Buyer and the Sellers within 15 days after the end of the Cure Period, and absent such agreement, by the Houston office of the American Arbitration Association (the “Title Arbitrator”). The arbitration proceeding shall be held in Houston, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section. The Title Arbitrator’s determination shall be made within 20 days after submission of the matters in dispute and shall be final and binding upon both parties, without right of appeal. In making his determination, the Title Arbitrator shall be bound by the provisions of Sections 2.05(b)(vii) and 2.05(b)(viii) and, subject to the foregoing, may consider such other matters as in the opinion of the Title Arbitrator are necessary to make a proper determination. The Title Arbitrator, however, may not award the Buyer a greater Title Defect Amount than the Title Defect Amount claimed by Buyer in its applicable Title Defect Notice and may not award the Sellers a greater Title Benefit Amount than the Title Benefit Amount claimed by the Sellers in its applicable Title Benefit Notice. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defect, Title Benefit, Title Defect Amounts and/or Title Benefit Amounts submitted by either party and may not award damages, interest or penalties to either party with respect to any matter. The Sellers and Buyer shall each bear its own legal fees and other costs of presenting its case. The non-prevailing party shall bear the costs and expenses of the Title Arbitrator. To the extent that the award of the Title Arbitrator with respect to any Title Defect Amount or Title Benefit Amount is not taken into account as an adjustment to the Purchase Price pursuant to Section 2.05(b), then within ten days after the Title Arbitrator delivers written notice to Buyer and the Sellers of his award with respect to a Title Defect Amount or a Title Benefit Amount, and subject to the other terms and provisions hereof, (A) Buyer shall pay to the Sellers the amount, if any, so awarded by the Title Arbitrator to the Sellers and (B) the Sellers shall pay to Buyer the amount, if any, so awarded by the Title Arbitrator to Buyer.

(xi) Casualty or Condemnation Loss.

(A) Notwithstanding anything herein to the contrary and subject to the termination rights set forth below, from and after the Effective Time, subject to the Closing, Buyer shall assume all risk of loss with respect to production of Hydrocarbons through normal depletion (including watering out of any well, collapsed casing or sand infiltration of any well) and the depreciation of personal property due to ordinary wear and tear, in each case, with respect to the assets of the Company and its Subsidiaries.

(B) If, after the date of this Agreement but prior to the Closing Date, any portion of the Oil and Gas Interests is destroyed by fire or other casualty or is

taken in condemnation or under right of eminent domain, and the aggregate amount of any such loss or taking exceeds ten percent (10%) of the Purchase Price, either Buyer or the Sellers shall have the right to terminate this Agreement, in which event this Agreement shall terminate and the LOC Deposit shall be returned to Buyer. If the aggregate amount of any such loss or taking is ten percent (10%) or less of the Purchase Price, this Agreement may not be terminated based on such loss or taking. If the loss as a result of such individual casualty or taking exceeds $25,000 and the parties proceed to Closing, the parties shall treat such casualty or taking as a Title Defect with respect to the affected Oil and Gas Interests under this Section 2.05, including the dispute resolution provisions, except that for purposes of this Section 2.05(b)(xi): (1) the Title Claim Date shall be the Closing Date; (2) the Title Defect Amount shall be the difference between the cost to replace or repair the Oil and Gas Interests that are destroyed by fire or other casualty or are taken in condemnation or under right of eminent domain and the estimated insurance or other proceeds the Company is entitled to as a result of such destruction or taking.

(C) If any action for condemnation or taking under right of eminent domain is pending or threatened with respect to any Oil and Gas Interests of the Company or its Subsidiaries or portion thereof after the date of this Agreement, but no taking of such Oil and Gas Interests or portion thereof occurs prior to the Closing Date, Buyer shall nevertheless be required to close the transactions contemplated by this Agreement and the Sellers, at Closing, shall assign, transfer and set over to Buyer or subrogate Buyer to all of the Sellers’ right, title and interest (if any) in such condemnation or eminent domain action, including any future awards therein, insofar as they are attributable to such Oil and Gas Interests threatened to be taken, except that the Sellers shall reserve and retain (and Buyer shall assign to the Sellers) all rights, titles, interests and claims against third parties for the recovery of the Seller’s costs and expenses incurred prior to the Closing in defending or asserting rights in such action with respect to such Oil and Gas Interests.

2.06 Gas Imbalance Adjustment. To the Sellers’ knowledge, each of the net overproduction and underproduction of gas from the Oil and Gas Interests as of the Effective Date is shown on Schedule 2.06. Buyer shall have a period of six months following Closing to verify such imbalances. If Buyer notifies the Sellers within such period that such overproduction exceeded the amount shown on Schedule 2.06 by more than 0.5 billion cubic feet or such underproduction is less than the amount shown on Schedule 2.06 by 0.5 billion cubic feet, and thereafter promptly provides to the Sellers all reasonable evidence supporting such conclusion, the Sellers shall have thirty (30) days following the receipt of such information to object in writing to Buyer’s calculations or information. If the Sellers notify Buyer in writing of its objection within such thirty (30) day period, and the parties cannot agree on the amount of overproduction or underproduction within thirty (30) days following such written objection notice, the matter shall be arbitrated in accordance with the provisions of Section 2.05, with the deadline for selection of a mutually acceptable auditor being ten days following the foregoing thirty-day resolution-by-agreement period. The Sellers shall pay to Buyer $4.00 per thousand cubic feet of the actual volume of overproduction less the amount shown on Schedule 2.06 for

such overproduction within five business days following the period for the Sellers to object, if no objection is made, or within five business days following resolution of the matter by agreement or arbitration, whichever occurs. Buyer shall pay to the Sellers $4.00 per thousand cubic feet for the difference between the amount shown on Schedule 2.06 for such underproduction and the actual volume of underproduction within five business days following the period for the Sellers to object, if no objection is made, or within five business days following resolution of the matter by agreement or arbitration, whichever occurs. Such overproduction and underproduction payments shall be netted against each other to the extent possible. This Section 2.06 contains the sole and exclusive obligation of each of the Sellers and Buyer with respect to natural gas imbalances.

2.07 Environmental Adjustment.

(a) Inspection and Testing.

(i) Prior to Closing, Buyer shall have the right, at its sole cost and expense, to review the Company’s and its Subsidiaries’ Phase I environmental assessments of the Oil and Gas Interests and to conduct any further Phase I or other non-invasive environmental assessment of the Oil and Gas Interests it deems appropriate, to the extent that the Company and its Subsidiaries have the authority to grant such right to Buyer; provided that the Company and its Subsidiaries shall use commercially reasonable efforts to obtain all authority necessary to grant to Buyer the right to all Phase I or other non-invasive environmental assessments that Buyer determines are necessary with respect to the Oil and Gas Interests. Buyer shall promptly provide to the Company any reports prepared by third party consultants for Buyer. The Company and its Subsidiaries and Buyer shall keep all information relating to such assessments and any internal documents regarding Buyer’s environmental assessments strictly confidential whether or not Closing occurs, except as may be required pursuant to any Environmental Laws.

(ii) Buyer waives and releases all claims against the Sellers, their affiliates, and each of their respective partners, members, directors, officers, employees, agents and other representatives and their successor and assigns (collectively, the “Sellers’ Group”), for injury to or death of persons, or damage to property, arising in any way from the exercise of rights granted to Buyer pursuant to this Section 2.07 or the activities of Buyer or its employees, agents or contractors on the Oil and Gas Interests in connection therewith. BUYER SHALL INDEMNIFY THE SELLERS’ GROUP AGAINST AND HOLD THE MEMBERS OF THE SELLERS’ GROUP HARMLESS FROM ANY AND ALL LOSS, COST, DAMAGE, EXPENSE OR LIABILITY WHATSOEVER, INCLUDING ATTORNEY’S FEES, ARISING OUT OF (I) ANY AND ALL STATUTORY OR COMMON LAW LIENS OR OTHER ENCUMBRANCES FOR LABOR OR MATERIALS FURNISHED IN CONNECTION WITH SUCH TESTS, SAMPLINGS, STUDIES OR SURVEYS AS BUYER MAY CONDUCT WITH RESPECT TO THE OIL AND GAS INTERESTS; AND (II) ANY INJURY TO OR DEATH OF PERSONS OR DAMAGE TO PROPERTY OCCURRING IN, ON OR ABOUT THE OIL AND GAS INTERESTS AS A RESULT OF SUCH EXERCISE OR ACTIVITIES, NOTWITHSTANDING THE SOLE, JOINT OR CONCURRENT NEGLIGENCE OR STRICT LIABILITY OF, OR BREACH OF REPRESENTATION,

WARRANTY OR CONTRACT BY, ANY OF THE SELLERS’ GROUP, BUT EXCLUDING, HOWEVER, THOSE LOSSES, COSTS, DAMAGES, EXPENSES AND LIABILITIES ARISING OUT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE SELLERS OR ANY REPRESENTATIVE, EMPLOYEE, CONSULTANT, INDEPENDENT CONTRACTOR OR SUBCONTRACTOR OF THE SELLERS.

(b) Assertions of Environmental Conditions. Buyer must deliver claim notices to the Sellers meeting the requirements of this Section 2.07 an (“Environmental Defect Notice”) not later than ten (10) days prior to Closing (the “Environmental Claim Date”) setting forth any matters which, in Buyer’s reasonable opinion, constitute an Environmental Condition and which Buyer intends to assert as an Environmental Condition pursuant to this Section 2.07; provided however, nothing in this subsection prevents Buyer from delivering more than one Environmental Defect Notice, so long as all such Environmental Defect Notices are delivered prior to the Environmental Claim Date. For all purposes of this Agreement, Buyer shall be deemed to have waived any Environmental Condition which Buyer fails to assert as an Environmental Condition by an Environmental Defect Notice received by the Sellers on or before the Environmental Claim Date. To be effective, each Environmental Defect Notice shall be in writing and shall include (i) a description of the matter constituting the alleged Environmental Condition, (ii) a description of each Oil and Gas Interest (or portion thereof) that is affected by the alleged Environmental Condition, (iii) Buyer’s assertion of the Allocated Value of the portion of the Oil and Gas Interest affected by the alleged Environmental Condition, (iv) supporting documents reasonably necessary for the Sellers to verify the existence of the alleged Environmental Condition, and (v) a calculation of the Remediation Amount (itemized in reasonable detail) that Buyer asserts is attributable to such alleged Environmental Condition. Buyer’s calculation of the Remediation Amount included in the Environmental Defect Notice must describe in reasonable detail the Remediation proposed for the asserted Environmental Condition and identify all assumptions used by the Buyer in calculating the Remediation Amount, including the standards that Buyer asserts must be met to comply with Environmental Laws. The Sellers shall have the right, but not the obligation, to cure any claimed Environmental Condition on or before Closing. It shall be Buyer’s sole responsibility to inspect, investigate, and assess any Environmental Conditions prior to the Environmental Claim Date.

(c) Remedies for Environmental Conditions. Subject to the Sellers’ continuing right to dispute the existence of an Environmental Condition and/or the Remediation Amount asserted with respect thereto, in the event that any Environmental Condition timely asserted by Buyer in accordance with Section 2.07(b) is not waived in writing by Buyer or cured on or before Closing, the Sellers shall, at their sole option, elect to:

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

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

(iii) retain the entirety of the Oil and Gas Interest that is subject to such Environmental Condition, together with all associated Oil and Gas Interests, in which

event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such asset and such associated Oil and Gas Interests; or

(iv) if applicable, terminate this Agreement pursuant to Section 9.01.

If the Sellers elects the option set forth in clause (ii) above, the Sellers shall use reasonable efforts to implement such Remediation in a manner which is consistent with the requirements of Environmental Laws in a timely fashion for the type of Remediation that the Sellers elect to undertake and shall have reasonable access to the affected Oil and Gas Interests after the Closing Date to implement and complete such Remediation. In connection with the grant of access to the Oil and Gas Interests in this Section 2.07(c), Sellers represent that they are adequately insured and waive, release and agree to indemnify Buyer and its parent, affiliates, directors, officers, shareholders, employees, agents, partners, members, and representatives against all claims for injury to, or death of, persons or for damage to property arising in any way from the access afforded to Sellers hereunder or the activities of Sellers. THE FOREGOING INDEMNITY SHALL BE ENFORCEABLE REGARDLESS OF WHETHER ANY PERSON (INCLUDING THE INDEMNIFYING PARTY) ALLEGES OR PROVES (i) NEGLIGENCE (INCLUDING SOLE NEGLIGENCE, SINGLE NEGLIGENCE, JOINT NEGLIGENCE, CONCURRENT NEGLIGENCE, ACTIVE OR PASSIVE NEGLIGENCE, BUT EXPRESSLY NOT INCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF ANY INDEMNIFIED PARTY, OR (ii) STRICT LIABILITY. THE PARTIES HERETO AGREE THAT THE FOREGOING COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS. THIS WAIVER, RELEASE AND INDEMNITY BY SELLERS SHALL SURVIVE THE CLOSING. The Sellers will be deemed to have adequately completed the Remediation required in the immediately preceding sentence (A) upon receipt of a certificate or approval from the applicable Governmental Entity that the Remediation has been implemented to the extent necessary to comply with existing regulatory requirements equal to but no more stringent than as required for land use of the Oil and Gas Interests as of the Closing Date or (B) upon written consent of Buyer which consent may not be unreasonably withheld or delayed.

(d) Exclusive Remedy. Subject to Section 2.07(e), Section 2.07(c) shall be the exclusive right and remedy of Buyer with respect to any Environmental Condition other than any right or remedy Buyer may have for the breach of the representations contained in Section 4.16, which right shall be in addition to the remedy provided in Section 2.07(c). Buyer hereby waives any claims of cost recovery or contribution from the Sellers related to the Oil and Gas Interests under any Environmental Laws or any other cause of action.

(e) Environmental Deductibles. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided by the Sellers for any individual Environmental Condition for which the Remediation Amount does not exceed $1,000,000 (“Individual Environmental Threshold”); and (ii) in no event shall there be any adjustments to the Purchase Price or other remedies provided by the Sellers for any Environmental Condition for which the Remediation Amount exceeds the Individual Environmental Threshold unless (A) the sum of (1) the Remediation Amounts of all such

Environmental Conditions that exceed the Individual Environmental Threshold, in the aggregate, excluding any Environmental Conditions cured by the Sellers, plus (2) the Title Defect Amounts of all Title Defects, in the aggregate, excluding any individual Title Defect for which the Title Defect Amount does not exceed the Individual Title Defect Threshold and any Title Defects cured by the Sellers, (B) exceeds the Aggregate Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price or other remedies only with respect to such Environmental Conditions in excess of such Aggregate Deductible.

(f) Environmental Dispute Resolution. The Sellers and Buyer shall attempt to agree on all Environmental Conditions and Remediation Amounts prior to Closing and as to the completion of Remediation efforts after Closing. If the Sellers and Buyer are unable to agree by Closing (or, after Closing, as to the completion of Remediation efforts), the Environmental Conditions and/or Remediation Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 2.07. There shall be a single arbitrator, who shall be an environmental attorney with at least ten years experience in environmental matters involving oil and gas properties, as selected by mutual agreement of Buyer and the Sellers within fifteen days after the Closing Date, or within fifteen days after the Sellers claim completion of Remediation efforts after Closing, as applicable, and absent such agreement, by the Houston office of the American Arbitration Association (the “Environmental Arbitrator”). The arbitration proceeding shall be held in Houston, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Article. The Environmental Arbitrator’s determination shall be made within twenty days after submission of the matters in dispute and shall be final and binding upon Buyer and the Sellers, without right of appeal. In making his or her determination, the Environmental Arbitrator shall be bound by the provisions set forth in this Section 2.07 and, subject to the foregoing, may consider such other matters as in the opinion of the Environmental Arbitrator are necessary or helpful to make a proper determination. The Environmental Arbitrator, however, may not award the Buyer more than the Remediation Amount claimed by Buyer in its applicable Environmental Defect Notice. The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Conditions and/or Remediation Amounts submitted by a party and may not award damages, interest or penalties to any party with respect to any matter. The Sellers and Buyer shall each bear their own legal fees and other costs of presenting their case. The non-prevailing party shall bear the costs and expenses of the Environmental Arbitrator, such non-prevailing party to be designated by the Environmental Arbitrator; provided however, if the Environmental Arbitrator is unable or unwilling to designate a non-prevailing party and the Sellers and the Buyer cannot agree among themselves as to which is the non-prevailing party, the Sellers and the Buyer shall share the costs and expenses of the Environmental Arbitrator in equal portions. To the extent that the award of the Environmental Arbitrator with respect to any Remediation Amount is not taken into account as an adjustment to the Purchase Price pursuant to Section 2.07, then within ten days after the Environmental Arbitrator delivers written notice to Buyer and the Sellers of his or her award with respect to a Remediation Amount, and subject to Section 2.07 and the other terms and provisions hereof, (i) Buyer shall pay to the Sellers the amount, if any, so awarded by the Environmental Arbitrator to the Sellers and (ii) the Sellers shall pay to Buyer the amount, if any, so awarded by the Environmental Arbitrator to Buyer.

(g) NORM, Wastes and Other Substances. Buyer acknowledges that the Oil and Gas

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

2.08 Tax Treatment of Adjustments to the Purchase Price. For Tax purposes, the parties agree to treat all payments made under Article II, or under any indemnity provisions contained in this Agreement, or for breaches of representations, warranties, covenants or agreements, as adjustments to the Purchase Price.

(c) Insofar as the title claims and demands of all persons claiming, or to claim any interest in the Oil and Gas Interests, Sellers, the Company and its Subsidiaries specially warrant by, through or under Sellers, the Company or its Subsidiaries, but not otherwise that:

Except as set forth on Schedule 4.08, neither the Company nor any of its Subsidiaries is currently the beneficiary of any extension of time within which to file any Tax Return. To the Sellers’ knowledge, no claim has ever been made by an authority in a jurisdiction where the Company or any of its Subsidiaries does not file Tax Returns that the Company or any of its Subsidiaries is or may be subject to taxation by that jurisdiction. There are no Liens other than Permitted Liens on any of the assets of the Company or any of its Subsidiaries that arose in connection with any failure (or alleged failure) to pay any Tax.

(b) The Company and each of its Subsidiaries has withheld and paid, if due, all Taxes that they are required to withhold and pay in connection with amounts paid or owing to any Person except where any such failure to withhold or pay would not have a Material Adverse Effect.

(c) Except as set forth on Schedule 4.08: (i) there is no litigation concerning any liability for Taxes of the Company or any of its Subsidiaries, either (A) claimed or raised by any authority and delivered to the Company or any of its Subsidiaries in writing or (B) to the Sellers’ knowledge, based upon personal contact with any agent of such authority; and (ii) no Tax audits or other administrative proceedings or court proceedings are presently pending or, to the Sellers’ knowledge, threatened with regard to any Taxes for which the Company or any of its Subsidiaries has been or will be liable.

(e) Except as set forth on Schedule 4.08, neither the Company nor any of its Subsidiaries has waived any statute of limitations with respect to any Taxes or agreed to any extension of time with respect to a Tax assessment or deficiency (where such waiver or extension is still in effect), and no power of attorney granted by the Company or any of its Subsidiaries with respect to any Tax matter is currently in force.

(h) All deficiencies asserted or assessments made as a result of any examinations of the Company or any of its Subsidiaries have been fully paid, or are fully reflected as a liability in the Audited Financial Statements or First Fiscal Quarter 2007 Financial Statements, or are being contested and an adequate reserve therefor has been established and is fully reflected in the Audited Financial Statements or First Fiscal Quarter 2007 Financial Statements.

(i) Neither the Company nor any of its Subsidiaries has constituted either a “distributing corporation” or a “controlled corporation” within the meaning of Section 355(a)(1)(A) of the Code in a distribution of stock intended to qualify under Section 355(a) of the Code (a) in the two (2) years prior to the date of this Agreement (or will constitute such a corporation in the two (2) years prior to the Closing Date) or (b) in a distribution that otherwise constitutes part of a “plan” or “series of related transactions” within the meaning of Section 355(e) of the Code.

(j) Neither the Company nor any of its Subsidiaries has participated in any “reportable transaction” within the meaning of Section 1.6011-4 of the Treasury Regulations.

(k) The due but unpaid Taxes of the Company and its Subsidiaries did not, as of December 31, 2006, exceed the reserve for Tax liability (rather than any reserve for deferred Taxes, established to reflect timing differences between book and Tax income) set forth on the face of the Audited Financial Statements or First Fiscal Quarter 2007 Financial Statements (rather than in any notes thereto) and the due but unpaid Taxes as of the date hereof do not (and as of the Closing Date will not) exceed that reserve as adjusted for the passage of time through the Closing Date in accordance with the past custom and practice of the Company and its Subsidiaries in filing their Tax Returns.

(l) The Company has always been treated as a partnership for federal income Tax purposes, and neither the Company nor ▇▇▇▇▇▇ Enterprises has made an election (nor will such election be made prior to the Closing Date) to be treated as an association taxable as a corporation for federal income Tax purposes. Each Subsidiary (other than ▇▇▇▇▇▇ Enterprises) has always been treated as a corporation for federal income Tax purposes. ▇▇▇▇▇▇ Enterprises has always been disregarded from ▇▇▇▇▇▇ Delaware for federal income Tax purposes.

(m) Ninety percent (90%) or more of the income earned by ▇▇▇▇▇▇ Delaware, ▇▇▇▇▇▇ Enterprises, ▇▇▇▇▇▇ Property Company, and ▇▇▇▇▇ Gathering Company from January 1, 2007 until the Closing date will be “qualifying income” within the meaning of Section 7704(d) of the Code.

(n) The Company is not a party to any joint venture, partnership or other arrangement or contract that could be treated as a partnership for federal income Tax purposes.

(o) Except as set forth on Schedule 4.08, neither the Company nor any of its Subsidiaries has been a member of any affiliated, consolidated, combined, unitary or similar group other than a group in which ▇▇▇▇▇▇ Delaware was the common parent.

Except as listed on Schedule 4.13(a), with respect to employees, directors and independent contractors of the Company or any of its Subsidiaries, neither the Company nor any of its Subsidiaries maintains, participates in or contributes to, whether written or unwritten, any “pension plans” (as defined under Section 3(2) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)), “welfare plans” (as defined under Section 3(1) of ERISA), or any stock purchase, stock option, restricted stock, severance, employment, bonus, change in control, retention, termination, fringe benefit, incentive, deferred compensation, employee loan or other employee benefit plans, agreements, programs, policies or arrangements (“Plans”). Each of the Plans that is intended to be qualified under Section 401(a) of the Internal Revenue Code of 1986, as amended (the “Code”), is so qualified and has received a favorable determination letter from the Internal Revenue Service or is a prototype plan that is entitled to rely on an opinion letter issued by the Internal Revenue Service to the prototype plan sponsor regarding qualification of the form of the prototype plan. To the Sellers’ knowledge, nothing has occurred that could be expected to adversely affect a Plan’s qualified status. The Plans have been administered in accordance with their respective terms and comply in form and in operation in all material respects with the requirements of the Code, ERISA and all other applicable Laws. Since January 1, 2005, each Plan that is a “nonqualified deferred compensation plan” (as defined under Code

Section 409A) has been operated in compliance with Code Section 409A and the guidance promulgated thereunder. Neither the Company and its Subsidiaries nor any “party in interest” or “disqualified person” (as defined in Code Section 4975(e) and ERISA Section 3(14)) has engaged in any “prohibited transaction” (as defined in Code Section 4975 and ERISA Section 406) with respect to any Plan, and, with respect to each Plan, no fiduciary has breached the responsibilities or obligations imposed under Title I of ERISA.

Neither the Company nor any of its Subsidiaries has any material obligation to provide post employment health, life or other welfare benefits other than as required under Section 4980B of the Code or any similar applicable Laws. No Plan is (i) an “employee stock ownership plan” (as defined in Code Section 4975(e)(7)) or otherwise invests in employer securities (as defined in Code Section 409) or (ii) a “voluntary employees’ beneficiary association” (as defined in Code Section 501(c)(9)).

(e) Except as set forth on Schedule 4.13(e), the consummation of the transactions contemplated by this Agreement will not (i) result in any payment becoming due or owing pursuant to a Plan or (ii) accelerate the vesting or timing of the payment of any benefits payable pursuant to a Plan. No amount required to be paid or that is payable in connection with the consummation of the transactions contemplated by this Agreement will be “excess parachute payments” (as defined in Code Section 280G).

4.14 Insurance.

(a) Each of the Company and its Subsidiaries maintains insurance coverage with respect to its properties and business of such a nature, in such amounts, with such terms, and covering such risks as required by the Company Contracts or applicable Laws. All such policies are in full force and effect. Neither the Company nor any Subsidiary has received notice of default under any such policy, nor has it received notice of any pending or, to the Sellers’ knowledge, threatened termination or cancellation, coverage limitation or reduction, or material premium or deductible increase with respect to any such policy. The insurance policies currently

in effect are sufficient to operate the Business as now conducted and currently proposed to be conducted and there have been no lapses in the insurance coverage of the Company and its Subsidiaries during the last seven (7) years (or since the respective formation dates of the Company and its Subsidiaries, if within the last seven years).

(b) Schedule 4.14 contains a complete list of all insurance policies (including performance bonds) carried by or for the benefit of the Company or any of its Subsidiaries, specifying the insurer, the amount of and nature of coverage, the risk insured against, the deductible amount (if any), the date through which coverage shall continue by virtue of premiums already paid. None of the policy limits of such insurance have been exhausted, nor has the Company or any of its Subsidiaries failed to give any notice or to present any claim thereunder in due and timely fashion. To the Sellers’ knowledge, neither the Company nor any of its Subsidiaries has received any notice of the intent of any insurance company to not renew or to cancel any insurance policies of the Company or its Subsidiaries or materially increase the premiums thereunder, and none of the insurance policies shall terminate as a result of the transactions contemplated hereby. No insurance company has reserved rights with respect to any material claim made pursuant to an insurance policy of the Company or its Subsidiaries.

Except as set forth on Schedule 4.15, to the knowledge of the Company, its Subsidiaries and the Sellers, the Company and its Subsidiaries hold, and are in material compliance with, all permits, licenses, certificates, accreditations or other authorizations or consents of a Governmental Entity (“Permits”) required for the conduct of the businesses of the Company and its Subsidiaries (including the operation of the Company’s and its Subsidiaries’ real property, assets and Oil and Gas Interests) and such Permits are in full force and effect and there have been no material violations thereof which have not been resolved.

ARTICLE VIII
INDEMNIFICATION

8.01 Survival of Representations, Warranties, Covenants, Agreements and Other Provisions. The representations and warranties in this Agreement and all covenants contained in this Agreement shall survive the Closing until one (1) year after the Closing Date (the “Expiration Date”), except that (a) the representations and warranties in Sections 4.03, 4.04 and 4.07(c) shall survive indefinitely, (b) the representations and warranties in Section 4.08 shall survive until three (3) years after the Closing Date if the Tax Insurance Policy has been delivered and accepted by Buyer prior to ▇▇▇▇▇▇ ▇▇, ▇▇▇▇ (▇▇ not delivered and accepted by Buyer by August 31, 2007, the representations and warranties shall survive the Closing until one (1) year after the Closing Date), and (c) certain covenants with a specified expiration date shall continue in effect as provided therein. Notwithstanding the foregoing, if, prior to the close of business on the applicable Expiration Date, an Indemnitor (as defined in Section 8.05(a) below) shall have been properly notified of a claim for indemnity hereunder and such claim shall not have been finally resolved or disposed of at such Expiration Date, such claim shall continue to survive and shall remain a basis for indemnity hereunder until such claim is finally resolved or disposed of in accordance with the terms hereof.

8.02 Indemnification for the Benefit of Buyer. Subject to the terms of this Article VIII, each of the Company (solely prior to the Closing Date), and the Sellers severally, but not jointly, agree to indemnify Buyer, the Company (solely after the Closing Date) and each of Buyer’s and the Company’s (solely after the Closing Date) respective officers, directors, employees, agents, representatives, affiliates, successors and permitted assigns (collectively, the “Buyer Parties”) and hold each of them harmless from and against and pay on behalf of or reimburse such Buyer Parties in respect of any direct losses, liabilities, damages, judgments, penalties and expenses (including reasonable legal fees and expenses) (“Loss(es)”) which any such Buyer Party may

suffer, sustain or become subject to, as a result of:

(a) the breach of any representation or warranty made by the Company contained in Article IV or any certificate delivered by a Seller to Buyer with respect hereto in connection with the Closing; or

(b) the breach of any covenant or agreement to be performed by the Sellers or the Company (solely with respect to the Company, to be performed on or prior to the Closing) contained in this Agreement or any certificate delivered by the Sellers to Buyer with respect hereto in connection with the Closing.

8.03 The Buyer’s Indemnification Obligation. Subject to the terms of this Article VIII, Buyer shall indemnify the Sellers and each of their respective officers, directors, employees, stockholders, agents, representatives, affiliates, successors and permitted assigns (collectively, “Seller Parties”) and hold them harmless from and against and pay on behalf of or reimburse such Seller Parties in respect of any Loss which any Seller Party may suffer, sustain or become subject to, as the result of:

(a) the breach of any representation or warranty made by Buyer contained in Article V or any certificate delivered by Buyer to the Sellers with respect hereto in connection with the Closing; or

(b) the breach of any covenant or agreement made by Buyer contained in this Agreement or any certificate delivered by Buyer to the Sellers with respect hereto in connection with the Closing.

8.04 Limitations on Indemnity.

(a) Notwithstanding anything in this Agreement to the contrary except for Section 8.4(d) below, which specifically modifies this Section 8.04(a), (i) the Sellers and the Company shall not be liable to the Buyer Parties for any Loss arising under Section 8.02, (A) unless the aggregate amount of all such Losses exceeds $750,000, including any Losses relating to a Tax Indemnification Obligation up to the amount of the Tax Indemnification Threshold (the “Sellers’ Indemnification Threshold”), in which case such parties shall be liable for all such Losses to the extent such Losses exceed the Sellers’ Indemnification Threshold; provided that, in the case of any Loss arising under Section 4.07(c), Sellers’ Indemnification Threshold shall not be applicable and only the limitations contained in Section 4.07(c) shall be applicable, or (B) to the extent the aggregate amount of all Losses indemnified by the Sellers and the Company exceeds five percent (5%) of the Purchase Price (the “Cap”), and (ii) each Seller’s liability for any Loss shall be limited to a percentage share of such Loss equal to such Seller’s percentage interest in the Purchase Price as set forth on Schedule 8.4(a) (which schedule shall include the amount of cash proceeds, Buyer Units and percentage of Purchase Price applicable to each Seller).

(b) Notwithstanding anything herein to the contrary, Buyer shall not be liable to the Seller Parties for any Loss arising under Section 8.03, (i) unless the aggregate amount of all such Losses exceeds $750,000 in the aggregate (the “Buyer Indemnification Threshold”), in which case Buyer shall be liable for all such Losses to the extent such Losses exceed the Buyer Indemnification Threshold, or (ii) to the extent the aggregate amount of all Losses indemnified by

Buyer exceeds the Cap.

(c) The amount of any Loss subject to indemnification under this Article VIII shall be calculated net of any insurance proceeds or any indemnity, contribution or other similar payment actually received by any Buyer Party or Seller Party from any third party with respect thereto. The Indemnitee (as defined in Section 8.05 below) shall use commercially reasonable efforts to seek recovery under all insurance policies and any other rights to indemnification covering any Loss to the same extent as they would if such Loss were not subject to indemnification hereunder. In the event that an insurance or other recovery is made by any Indemnitee with respect to any Loss for which any such Person has been indemnified hereunder, then a refund equal to the aggregate amount of the recovery shall be made promptly to the Indemnitor (as defined in Section 8.05 below).

(d) The parties intend for Buyer to obtain the Tax Insurance Policy to provide insurance coverage for breaches of the representations and warranties of the Sellers of Section 4.08 and insurance coverage for Tax liability arising from any restructuring undertaken by the Company and/or any Subsidiary prior to the Closing Date (“Tax Indemnification Obligation”). If the Tax Insurance Policy has been delivered and accepted by Buyer, with respect to any Tax Indemnification Obligation, Buyer shall not be entitled to receive any proceeds until any Loss relating to a Tax Indemnification Obligation exceeds $250,000 in the aggregate (“Tax Indemnification Threshold”), in which case Buyer shall be able to receive, proceeds under the Tax Insurance Policy for all such Losses to the extent such Losses exceed the Tax Indemnification Threshold. If the Tax Insurance Policy has been delivered and accepted by Buyer, the aggregate amount of Losses for which Buyer shall be entitled to receive proceeds shall be limited only by the limits of the Tax Insurance Policy. The Sellers and Buyer agree that any proceeds received by Buyer under the Tax Insurance Policy shall not be counted as Losses limited by the Cap and shall not be subject to the Sellers’ Indemnification Threshold. If the Tax Insurance Policy has been delivered and accepted by Buyer, notwithstanding anything in this Agreement to the contrary, Buyer’s exclusive remedy for any breach of Section 4.08 shall be limited to Buyer’s recourse and recovery under the Tax Insurance Policy and the Sellers shall not be liable to Buyer for any breach of Section 4.08. If the Tax Insurance Policy has not been delivered and accepted by Buyer, this Section 8.04(d) shall have no force and effect.

(e) Except as set forth in Sections 2.05, 2.06, and 2.07, the Sellers, Buyer and the Company agree that (i) the remedies set forth in this Article VIII are the exclusive remedies of such parties for any breach of this Agreement or otherwise arising in connection with the transactions contemplated hereby, and (ii) the liability of the Sellers and the Company (before Closing) to Buyer and the Company (after Closing) shall be limited to the Cap in all circumstances, except as set forth in Section 8.04(d).

8.05 Defense of Third Party Claims.

(a) Any Person making a claim for indemnification under Section 8.02 or Section 8.03 (an “Indemnitee”) shall notify the indemnifying party (an “Indemnitor”) of the claim in writing promptly after receiving written notice of any action, lawsuit, proceeding, investigation or other claim against it (if by a third party), describing the claim, the amount thereof (if known and quantifiable) and the basis thereof; provided, however, that the failure to so notify the Indemnitor

shall relieve the Indemnitor from liability hereunder with respect to such claim only if, and only to the extent that, such failure to so notify the Indemnitor results in a material forfeiture by the Indemnitor of rights and defenses otherwise available to the Indemnitor with respect to such claim. Any Indemnitor shall be entitled to participate, upon written notice delivered to the Indemnitee within thirty (30) days of the receipt of Indemnitee’s notice of claim, in the defense of such action, lawsuit, proceeding, investigation or other claim giving rise to an Indemnitee’s claim for indemnification at such Indemnitor’s expense, and at its option shall be entitled to assume the defense thereof by appointing a reputable counsel reasonably acceptable to the Indemnitee to be the lead counsel in connection with such defense; provided, however, the Indemnitor shall not be entitled to assume the defense thereof if (A) such claim, based on the remedy sought, could result in criminal liability of, or injunctive or other equitable relief against, the Indemnitee or (B) the Indemnitee reasonably believes that the interests of the Indemnitor and the Indemnitee with respect to such claim are in conflict with one another, and as a result, the Indemnitor could not adequately represent the interests of the Indemnitee in such claim. In the event, however, that the Indemnitor declines or fails to assume the defense of such claim on the terms provided above or to employ counsel reasonably satisfactory to the Indemnitee, in either case within such 30-day period, or if the Indemnitor is not entitled to assume the defense of such claim in accordance with the preceding sentence, then the Indemnitor shall pay the reasonable fees and expenses of counsel for the Indemnitee as incurred; provided, however, that the Indemnitor shall not be required to pay the fees and disbursements of more than one firm for all Indemnitees in any jurisdiction in any single audit, investigation, action or proceeding. The Indemnitor or the Indemnitee (as the case may be) shall at all times use commercially reasonable efforts to keep the Indemnitor or Indemnitee (as the case may be) reasonably apprised of the status of the defense of any matter the defense of which it is maintaining and to cooperate in good faith with each other with respect to the defense of any such matter.

(b) No Indemnitee may settle or compromise any claim or consent to the entry of any judgment with respect to which indemnification is being sought hereunder without the prior written consent of the Indemnitor, unless (i) the Indemnitor fails to assume and maintain the defense of such claim pursuant to Section 8.05(a) or (ii) such settlement, compromise or consent includes an unconditional release of the Indemnitor and its officers, directors, employees and Affiliates from all liability arising out of such claim. An Indemnitor may not, without the prior written consent of the Indemnitee, settle or compromise any claim or consent to the entry of any judgment with respect to which indemnification is being sought hereunder unless (x) such settlement, compromise or consent includes an unconditional release of the Indemnitee and its officers, directors, employees and Affiliates from all liability arising out of such claim, (y) does not contain any admission or statement suggesting any wrongdoing or liability on behalf of the Indemnitee and (z) does not contain any equitable order, judgment or term that in any manner affects, restrains or interferes with the business of the Indemnitee or any of the Indemnitee’s Affiliates.

(c) In the event an Indemnitee claims a right to payment pursuant hereto, such Indemnitee shall send written notice of such claim to the appropriate Indemnitor. Such notice shall specify the basis for such claim. The failure by any Indemnitee so to notify the Indemnitor shall not relieve the Indemnitor from any liability that it may have to such Indemnitee with respect to any claim made pursuant to this Section 8.05(c). Any claim for indemnification that may be made under more than one subsection may be made under the subsection that the claiming

party may elect in its sole discretion, notwithstanding that such claim may be made under more than one subsection. In the event the Indemnitor disputes its liability with respect to such claim, as promptly as possible, such Indemnitee and the appropriate Indemnitor shall establish the merits and amount of such claim (by mutual agreement, litigation or otherwise) and, within five (5) business days following the final determination of the merits and amount, if any, of such claim, the Indemnitor shall pay to the Indemnitee in immediately available funds an amount equal to such claim as determined hereunder.

8.06 Disclaimers.

(a) Except as and to the extent expressly set forth in Article IV and elsewhere in this Agreement, (i) the Company and the Sellers make no representations or warranties, express, statutory or implied, and (ii) the Company and the Sellers expressly disclaim all liability and responsibility for any representation, warranty, statement or information made or communicated (orally or in writing) to Buyer or any of its Affiliates or Buyer’s Representatives (including, without limitation, any opinion, information, projection or advice that may have been provided to Buyer by any officer, director, employee, agent, consultant, representative or advisor of the Company, the Sellers or any of their respective Affiliates). In particular, except as expressly set forth in Article IV and elsewhere in this Agreement, and without limiting the generality of the foregoing, the Company and the Sellers expressly disclaim any representation or warranty, express, statutory or implied, as to (i) title to any of the Oil and Gas Interests or other assets of the Company and its Subsidiaries, (ii) the contents, character or nature of any report of any petroleum engineering consultant or any engineering, geological or seismic data or interpretation, relating to the Oil and Gas Interests or other assets of the Company and its Subsidiaries, (iii) the quantity, quality or recoverability of Hydrocarbons in or from the Oil and Gas Interests, (iv) any estimates of the value of the Oil and Gas Interests or other assets of the Company and its Subsidiaries or future revenues generated by such assets, (v) the production of Hydrocarbons from the Oil and Gas Interests, (vi) the maintenance, repair, condition, quality, suitability, design or marketability of the Oil and Gas Interests or other assets of the Company and its Subsidiaries, (vii) the content of any information memorandum, reports, brochures, charts or statements prepared by the Company, the Sellers or third parties with respect to the Oil and Gas Interests or other assets of the Company and its Subsidiaries, and (viii) any other materials or information that may have been made available to Buyer, its Affiliates, or Buyer’s Representatives in connection with the transactions contemplated by this Agreement or any discussion or presentation relating thereto. Except as expressly set forth in Article IV and elsewhere in this Agreement, the Company and the Sellers further disclaim any representation or warranty, express, statutory or implied, of merchantability, freedom from latent vices or defects, fitness for a particular purpose or conformity to models or samples of materials of any assets, rights of a purchaser under appropriate statutes to claim diminution of consideration or return of the Purchase Price, it being expressly understood and agreed by the parties hereto that Buyer shall be deemed to be obtaining the Oil and Gas Interests and other assets of the Company and its Subsidiaries in their present status, condition and state of repair, “as is” and “where is” with all faults or defects (known or unknown, latent, discoverable or undiscoverable), and that Buyer has made or caused to be made such inspections as Buyer deems appropriate. With respect to any such assets that are located in or in federal waters

offshore Louisiana, Buyer acknowledges that this waiver has been expressly called to its attention and includes, without limitation, a waiver of warranty against rehibitory vices arising under Louisiana Civil Code Articles 2520 through 2548, inclusive.

(b) The Sellers, the Company and Buyer agree that, to the extent required by applicable Laws to be effective, the disclaimers of certain representations and warranties contained in this Section 8.06 are “conspicuous” disclaimers for the purpose of any applicable Laws.

8.07 Non-Compensatory Damages. None of the Buyer Parties nor Seller Parties shall be entitled to recover from the Sellers or Buyer, or their respective Affiliates, any indirect, consequential, punitive or exemplary damages or damages for lost profits of any kind arising under or in connection with this Agreement or the transactions contemplated hereby. Buyer, on behalf of each of the Buyer Parties, and the Sellers, on behalf of each of Seller Parties, waive any right to recover punitive, special, exemplary and consequential damages, including damages for lost profits, arising in connection with or with respect to this Agreement or the transactions contemplated hereby.

ARTICLE IX

In the event the Sellers terminate this Agreement pursuant to Section 9.01(d) and are not in material breach of this Agreement at the time of such termination, the Sellers shall be entitled to payment of the full amount under the LOC Deposit and to retain such amount.

ARTICLE X
ADDITIONAL COVENANTS

10.01 Tax Matters.

(a) Prior to the Closing Date, the parties shall agree to an allocation of the Purchase Price among the Company’s assets for federal income Tax purposes (the “Allocation”).

(b) The Sellers and Buyer shall report the transactions contemplated hereby on all Tax Returns in a manner consistent with the Allocation. If the Purchase Price is adjusted pursuant to this Agreement, then the Sellers shall prepare such adjustment to the Allocation, which adjustment shall be submitted to Buyer, and the Sellers and Buyer shall use their best efforts to agree on the final adjustment within thirty (30) days after the determination of the adjusted Purchase Price. If, contrary to the intent of the parties hereto as expressed in this Section 10.01(b), any Governmental Entity makes or proposes an allocation different from the Allocation,

the Sellers and Buyer shall cooperate with each other in good faith to contest such Governmental Entity’s allocation (or proposed allocation); provided, however, that, after consultation with the party (or parties) adversely affected by such allocation (or proposed allocation), the other party (or parties) hereto may file such protective claims or Tax Returns as may be reasonably required to protect its (or their) interests.

(c) The Sellers shall prepare and timely file, or cause to be prepared and timely filed, the final federal income Tax Return for the Company on IRS Form 1065 for the period that ends on the Closing Date, and the Sellers shall be responsible for all Taxes due with respect to such Tax Return. Taxes of the Company and the Subsidiaries for any Tax period that includes but does not end on the Effective Time (a “Straddle Period”) shall be apportioned between Buyer and the Sellers as follows: (i) property and similar ad valorem Taxes or franchise Taxes based solely on capital shall be apportioned to the Sellers for the period until the Effective Time and to the Buyer for the period from and after the Effective Time on a ratable daily basis; and (ii) all other Taxes shall be apportioned based on an interim closing of the books of the Company as of the Effective Time. For purposes of this Section 10.01(c), any franchise Tax paid or payable with respect to the Company or any of its Subsidiaries shall be allocated to the taxable period during which the income, operations, assets or capital comprising the base of such Tax is measured, regardless of whether the right to do business for another taxable period is obtained by the payment of such Tax. Buyer shall file, or cause to be filed, all Tax Returns with respect to a Straddle Period. Buyer shall provide a copy of each such Tax Return at least twenty (20) days before the due date for such Tax Return. Five (5) days before the due date for such a Tax Return, the Sellers shall pay Buyer the excess, if any, of the Sellers’ share of the Taxes for such Straddle Period, as determined in this Section 10.01(c), over the accrual for such Taxes on the Closing Balance Sheet. If the accrual for such Taxes on the Closing Balance Sheet exceeds the Sellers’ share of the Taxes for such Straddle Period, as determined in this Section 10.01(c), the Buyer shall pay such excess to the Sellers five (5) days before the due date for such Tax Return. Buyer and the Sellers shall each provide the other with all information reasonably necessary to prepare a Tax Return with respect to the Company or its Subsidiaries.

(d) The Sellers shall prepare and file the federal income Tax Return for the Subsidiaries for the 2006 taxable year and shall pay the excess, if any, of the Taxes due on such Tax Returns over the accrual for such Taxes on the Closing Balance Sheet. If the accrual for such Taxes on the Closing Balance Sheet exceeds the Taxes due on such Tax Returns, the Buyer shall pay such excess to the Sellers five (5) days before the due date for such Tax Return. The Sellers shall provide Buyer with copies of such Tax Return at least 15 days prior to the due date for the filing of such Tax Return for Buyer’s review and comment. The Sellers shall consider such comments in good faith prior to the filing of any such Tax Return.

(e) Any tax-sharing agreement between the Sellers and the Company shall be terminated no later than the Closing Date and shall have no further effect for any taxable year (whether the current year, a future year, or a past year).

(f) The Sellers shall control and bear the cost of any audit or contest with respect to a Pre-Effective Time Tax Period or relating to income taxes attributable to the Company or any of its Subsidiaries prior to the Closing Date, and Buyer shall control and bear the cost of any other audit or contest; provided, however, that Buyer shall control and bear the cost of any audit or

contest with respect to a Straddle Period; provided further, that Buyer shall allow the Sellers to participate at the Sellers’ cost and expense. The party in control of an audit or controversy shall keep the other party reasonably informed of the status of the audit or controversy. Neither Buyer nor the Sellers shall settle any audit or contest in a way that would adversely affect the other party without the other party’s written consent, which the other party shall not unreasonably withhold. Buyer, the Company and its Subsidiaries, and the Sellers shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information reasonably relevant to any such audit, litigation, or other proceeding and making employees available without charge on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Company and its Subsidiaries, the Sellers, and Buyer agree (i) to retain all books and records with respect to Tax matters pertinent to the Company and its Subsidiaries relating to any taxable period beginning before the Closing Date until expiration of the statute of limitations (and, to the extent notified by Buyer or the Sellers, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (ii) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, the Company and its Subsidiaries or the Sellers, as the case may be, shall allow the other party to take possession of such books and records.

(g) Buyer and the Sellers shall each pay 50% of any real property sale and transfer or gains Tax, stamp Tax, stock transfer Tax, or other similar Tax imposed on the Sellers or its Subsidiaries solely as a result of the transfer of the Seller Securities contemplated by this Agreement (collectively, “Transfer Taxes”). Buyer and the Sellers shall each also pay 50% of any penalties or interest with respect to the Transfer Taxes. The Sellers agree to cooperate with Buyer in the filing of any returns with respect to the Transfer Taxes, including promptly supplying any information in their possession that is reasonably necessary to complete such returns.

(h) If the parties cannot agree, after good faith consultation, on the calculation of any Taxes that would result in a payment hereunder by one to the other or an adjustment of the purchase price, then each party shall deliver simultaneously to PricewaterhouseCoopers LLP (or if such firm is unwilling or unable to serve, another nationally recognized accounting firm mutually agreed on by the parties, the accounting firm ultimately chosen being referred to herein as the “Accountants”) such work papers and other reports and information relating to the disputed matter(s) as the Accountants may request and shall be afforded the opportunity to discuss the disputed matter(s) with the Accountants. The Accountants shall have thirty (30) days to carry out a review and prepare a written statement of its determination regarding the disputed matter(s) (including a statement regarding the Accountants’ determination of the prevailing party in any such disputed matter) which determination shall be final and binding upon the parties. Any fees and expenses of the Accountants incurred in resolving the disputed matter(s) shall be borne equally by the parties.

(i) The covenants in this Section 10.01 shall survive indefinitely; provided, however, that this Section 10.01 shall not be subject to the limits on liability and indemnity set forth in Article VIII hereof and; provided further, that the Sellers shall not be liable for the payment of

any Taxes pursuant to this Section 10.01 after the first anniversary of the Closing Date.

10.02 Further Assurances. From time to time, as and when requested by any party hereto and at such party’s expense, any other party shall execute and deliver, or cause to be executed and delivered, all such documents and instruments and shall take, or cause to be taken, all such further or other actions as such requesting party may reasonably deem necessary or desirable to evidence and effectuate the transactions contemplated by this Agreement.

10.03 Disclosure Generally. All Disclosure Schedules attached hereto are incorporated herein and expressly made a part of this Agreement as though completely set forth herein. All references to this Agreement herein or in any of the Disclosure Schedules shall be deemed to refer to this entire Agreement, including all Disclosure Schedules.

11.04 Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, except that neither this Agreement nor any of the rights, interests or obligations hereunder may be assigned or delegated by any Person without the prior written consent of the parties hereto; provided, however, that Buyer may, without prior written consent, assign any of its rights, interests or obligations hereunder to (i) any Affiliate for any reason or (ii) Buyer’s or the Company’s financing sources as collateral security for any financing; provided further, however, that no such assignment shall relieve Buyer of its obligations hereunder if the assignee does not perform its obligations hereunder.

11.05 Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable Laws, but if any provision of this Agreement is held to be prohibited by or invalid under applicable Laws, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

11.06 References. The table of contents and the Section and other headings and subheadings contained in this Agreement and the exhibits hereto are solely for the purpose of reference, are not part of the agreement of the parties hereto, and shall not in any way affect the meaning or interpretation of this Agreement or any exhibit hereto. All references to days or months shall be deemed references to calendar days or months. All references to “$” shall be deemed references to United States dollars. Unless the context otherwise requires, any reference to a “Section,” “Exhibit,” “Disclosure Schedule” or “Schedule” shall be deemed to refer to a Section of this Agreement, exhibit to this Agreement or a schedule to this Agreement, as applicable. The words “hereof,” “herein” and “hereunder” and words of similar import referring to this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement. English shall be the governing language of this Agreement. The word “including” shall mean “including, without limitation”.

11.07 Construction. The language used in this Agreement shall be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction shall be applied against any Person. The information contained in this Agreement and in the Disclosure Schedules and Exhibits hereto is disclosed solely for purposes of this Agreement, and no information contained herein or therein shall be deemed to be an admission by any party hereto to any third party of any matter whatsoever (including, without limitation, any violation of Laws or breach of contract).

11.08 Amendment, Waiver. Any provision of this Agreement or the Disclosure Schedules or Exhibits hereto may be amended only in a writing signed by Buyer and the Sellers. No waiver of any provision hereunder or any breach or default thereof shall extend to or affect in any way any other provision or prior or subsequent breach or default. Any provision of this Agreement or Disclosure Schedules or Exhibits may be waived only in writing signed by the party to be bound thereby. No waiver of any provision hereunder or any breach or default thereof shall extend to or affect in any way any other provision or prior or subsequent breach or default. No failure or delay on the part of any party hereto in the exercise of any right hereunder will impair such right or be construed to be a waiver of, or acquiescence in, any breach of any

representation, warranty or agreement herein, nor will any single or partial waiver by any party hereto of a breach of any provision hereunder operate or be construed as a waiver of any prior or subsequent breach of the same or any other provision hereunder.

11.09 Complete Agreement. This Agreement and the documents referred to herein (including the Escrow Agreement) and that certain Confidentiality Agreement dated December 26, 2006, contain the complete agreement between the parties hereto and supersede any prior understandings, agreements or representations by or between the parties, written or oral, which may have related to the subject matter hereof in any way.

11.10 Third Party Beneficiaries. Except as otherwise expressly provided herein, nothing expressed or referred to in this Agreement will be construed to give any Person other than the parties to this Agreement any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision of this Agreement.

11.11 Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or at law or in equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that 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 injunctive relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which they are entitled at law or in equity.

11.12 Arbitration. Except as otherwise expressly provided in this Agreement, if a dispute arises from or relates to this Agreement or the breach thereof, and if the dispute cannot be settled through direct discussions, the parties agree to endeavor first to settle the dispute by mediation administered by the AAA under its Commercial Mediation Rules before resorting to arbitration. Any unresolved controversy or claim arising from or relating to this Agreement or breach thereof shall be settled by arbitration administered by the AAA in accordance with its Commercial Arbitration Rules, then in effect. The decision of arbitration, unless clearly erroneous, shall be final and conclusive upon the parties, and judgment upon the award rendered by the arbitrator may be entered in any court having competent jurisdiction. The mediation, and arbitration proceedings shall be held in Houston, Texas. The arbitration proceedings shall be conducted before one (1) neutral arbitrator who shall be a member of the Texas Bar who has been actively engaged in the practice of corporate and oil and gas law for at least fifteen (15) years, and shall proceed under the Expedited Procedures of the Commercial Arbitration Rules. The arbitrator shall have authority to award any remedy or relief that a court of the State of Texas could order or grant, including specific performance of any obligation created under this Agreement, the issuance of an injunction, or the imposition of sanctions for abuse or frustration of the arbitration process. The arbitrator’s compensation, and the administrative costs of the arbitration, shall be borne by the parties in the manner set forth in the arbitration award, as determined by the arbitrator. The arbitrator, in the exercise of its sole discretion, shall have authority to award attorneys’ fees, costs, and expert witness fees to the prevailing party.

11.13 Delivery by Facsimile. This Agreement and any signed agreement entered into in

connection herewith or contemplated hereby, and any amendments hereto or thereto, to the extent signed and delivered by means of a facsimile machine, shall be treated in all manner and respects as an original contract and shall be considered to have the same binding legal effects as if it were the original signed version thereof delivered in person. At the request of any party hereto or to any such contract, each other party hereto or thereto shall re-execute original forms thereof and deliver them to all other parties. No party hereto or to any such contract shall raise the use of a facsimile machine to deliver a signature or the fact that any signature or contract was transmitted or communicated through the use of facsimile machine as a defense to the formation of a contract and each such party forever waives any such defense.

11.14 Counterparts. This Agreement may be executed in multiple counterparts, any one of which need not contain the signature of more than one party, but all such counterparts taken together shall constitute one and the same instrument.

11.15 Non-Compete. For the one (1) period after the Closing Date, neither J. ▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇ nor ▇▇▇▇▇ ▇▇▇▇ shall acquire, directly or indirectly, any interest in any oil and gas lease to the extent such lease covers and includes land within three (3) miles of any producing well set forth on Schedule B. Each of the above-named Persons agrees that such restriction is fair and reasonable both in length of time and in geographic scope and that such restriction will not preclude such Person for earning a living. Each Person agrees to execute a separate agreement prepared in good faith by Buyer and determined to be reasonably necessary by Buyer to carry out the terms of this Section 11.15, which agreement shall be delivered at Closing at the reasonable request of Buyer. Each of the above-named Persons agrees to the terms of this Section 11.15 severally and not jointly and agrees that Buyer’s remedies at law or in equity may be exercised against any single Person and are not required to be exercised against all Persons jointly and that the provisions of Article VIII shall not preclude Buyer from enforcing this provision in equity, it being agreed by the parties hereto that a calculation of Loss for a violation of this Section 11.15 would be impractical.

11.16 Governing Law. All issues and questions concerning the construction, validity, interpretation and enforceability of this Agreement and the exhibits and schedules hereto shall be governed by, and construed in accordance with, the Laws of the State of Texas, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Texas or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Texas.
