ARTICLE III

CONSIDERATION

Section 3.01 Purchase Price. The total consideration for the purchase, sale and assignment of the Assets by Seller to Buyer is Buyer’s payment to Seller of the sum of $127,000,000 (the “Purchase Price”) as adjusted pursuant to this Agreement (the “Adjusted Purchase Price”). The Adjusted Purchase Price shall be paid by Buyer to Seller at the Closing by means of a completed wire transfer to the account of Seller as designated by Seller to Buyer in writing prior to the Closing.

Section 3.02 Deposit.

(a) Concurrently with the execution and delivery of this Agreement, Buyer has deposited by wire transfer with Seller in same day funds the sum equal to ten percent (10%) of the Purchase Price (the “Deposit”). The Deposit shall be applied toward the Purchase Price at the Closing without any interest earned thereon.

(b) If (i) all conditions precedent to the obligations of Buyer set forth in Article VIII have been met and (ii) the transactions contemplated by this Agreement are not consummated on or before the Closing Date because of: (A) the failure of Buyer to materially perform any of its obligations hereunder or (B) the failure of any of Buyer’s representations or warranties hereunder to be true and correct in all material respects as of the Closing, then, in such event, Seller shall have the right to terminate this Agreement and retain the Deposit, as liquidated damages.

(c) If this Agreement is terminated by the mutual written agreement of Buyer and Seller or if the Closing does not occur on or before the Closing Date for any reason other than as set forth in Section 3.02(b), then Buyer shall be entitled to the delivery of the Deposit, free of any claims by Seller with respect thereto, but without any interest earned thereon. Buyer and Seller shall thereupon have the rights and obligations set forth in Section 12.02.

Section 3.03 Allocated Values and Value of Tag Along Assets.

(a) Buyer and Seller agree that the unadjusted Purchase Price is allocated among the Assets in the amounts set forth in Exhibit C – Part 1. The “Allocated Value” for any Asset equals the portion of the unadjusted Purchase Price allocated to such Asset on Exhibit C – Part 1 and to the extent there is any adjustment to the Purchase Price pursuant to this Agreement, such adjustment shall adjust the Allocated Values set forth on Exhibit C – Part 1 in accordance with Section 1060 of the Code. Buyer and Seller agree (a) that the Allocated Values, as adjusted, shall be used by Seller and Buyer as the basis for reporting Asset values and other items for purposes of all federal, state and local Tax Returns, including without limitation Internal Revenue Service Form 8594 and (b) that neither they nor their Affiliates will take positions inconsistent with such Allocated Values in notices to Governmental Authorities, in audit or other proceedings with respect to Taxes, in notices to holders of preferential purchase rights or in other documents or notices relating to the transactions contemplated by this Agreement. Each Party will

notify the other Party if it receives notice that the Internal Revenue Service proposes any allocation that is different from the allocation as set forth in Exhibit C – Part 1.

Section 3.04 Adjustments to Purchase Price.

(a) The Purchase Price for the Assets shall be adjusted as follows with all such amounts being determined in accordance with generally accepted accounting principles and Council of Petroleum Accountants Society (▇▇▇▇▇) standards:

(i) Reduced by the aggregate amount of the following proceeds received by Seller during the period between the Effective Time and the Closing Date (referred to herein as the “Adjustment Period”): (A) proceeds from the sale of Hydrocarbons (net of any royalties, overriding royalties or other burdens on or payable out of production, gathering, processing and transportation costs and any production, severance, sales or excise Taxes not reimbursed to Seller by the purchaser of production) produced from or attributable to the Assets during the Adjustment Period, and (B) other proceeds earned with respect to the Assets during the Adjustment Period;

(ii) the Deposit shall be credited against the Purchase Price in accordance with Section 3.02(a);

(iii) Reduced in accordance with Section 4.09, by an amount equal to the Allocated Value of those Assets with respect to which preferential purchase rights have been exercised prior to Closing and prior to the expiration of the applicable period of time within which the holder of any such preferential right is entitled to exercise the preferential right;

(iv) (A) Reduced as a result of Title Defects by the Title Defect Amount, to the extent required by Section 4.04, but subject to the limitations of Section 4.06, (B) increased as a result of Title Benefits by the Title Benefit Amount, to the extent required by Section 4.05(b), (C) increased or reduced, as applicable, as a result of Lease Adjustments pursuant to Section 4.13, and (D) reduced as a result of Environmental Defects by the Environmental Defect Amount, to the extent required by Section 5.04, but subject to the limitations of Section 5.05;

(v) Reduced by any other amount provided for in this Agreement or agreed upon by Buyer and Seller;

(vi) Increased by the value of all Hydrocarbons produced from or attributable to the Leases, the Units or the ▇▇▇▇▇ prior to the Effective Time that are in storage prior to sale as of the Closing Date, which value shall be calculated based upon the contract price for the sale of such Hydrocarbon;

(vii) Subject to the limitations of Section 7.04, increased by the amount of all Operating Expenses and other costs attributable to the ownership and operation of the Assets which are paid by Seller and incurred at or after the

Effective Time, except any Operating Expenses and other such costs already deducted in the determination of proceeds in Section 3.04(a) or already taken into account as a Lease Adjustment pursuant to Section 4.13;

(viii) Increased by any other amount provided for in this Agreement or agreed upon by Buyer and Seller; and

(ix) Increased or reduced, as appropriate, pursuant to the provisions of Section 7.07.

(b) Each adjustment made pursuant to Section 3.04(a)(i) shall serve to satisfy, up to the amount of the adjustment, Buyer’s entitlement under Section 2.04 to Hydrocarbon production from or attributable to the Assets during the Adjustment Period, and to the value of other income, proceeds, receipts and credits earned with respect to the Assets during the Adjustment Period, and as such, Buyer shall not have any separate rights to receive any production or income, proceeds, receipts and credits with respect to which an adjustment has been made.

(c) Similarly, the adjustment described in Section 3.04(a)(vii) shall serve to satisfy, up to the amount of the adjustment, Buyer’s obligation under Section 2.04 to pay the costs attributable to the ownership and operation of the Assets which are incurred during the Adjustment Period, and as such, Buyer shall not be separately obligated to pay for any such costs with respect to which an adjustment has been made.

ARTICLE IV

TITLE MATTERS

Section 4.01 Title Examination Period. Commencing on the date hereof and ending October 4, 2010 at 6:00 p.m. Midland, Texas time (the “Title Examination Period”), Seller shall, subject to Section 7.01, (a) permit Buyer and/or its representatives to examine, primarily by electronic “paper vision” and otherwise in a manner reasonably acceptable to Seller, at reasonable times and in Seller’s offices, all abstracts of title, title opinions, title files, ownership maps, Lease files, assignments, division orders, operating records and agreements (including the Contracts) and all other non-confidential and non-proprietary records and files pertaining to the Assets insofar as same may now be in existence and in the possession or control of Seller and (b) subject to Third Party operator approval, permit Buyer and/or its representatives, at reasonable times and at Buyer’s sole risk, cost and expense, to conduct reasonable inspections of the Assets (other than environmental inspections which are covered by Section 5.01 hereof).

Section 4.02 Title Defects. An Asset shall be deemed to have a “Title Defect” if Seller is found to have less than Defensible Title and it is reasonably estimated to (a) require an expenditure in excess of $25,000 to remedy or (b) reduce the value of such Asset by an amount in excess of $25,000. For purposes of this Agreement, the term “Defensible Title” shall mean

(a) with respect to any Tract identified on Exhibit C – Part 1, such title of Seller that, subject to and except for the Permitted Encumbrances:

(i) entitles Seller to receive not less than the percentage set forth in Exhibit C – Part 1 as the net revenue interest for any well drilled or which could

be drilled on such Tract of all Hydrocarbons produced, saved and marketed from such well, all without reduction of such interest throughout the duration of the productive life of such well, except (A) as specifically set forth in Exhibit C – Part 1, (B) decreases in connection with those operations in which Seller may from and after the date of this Agreement be a non-consenting co-owner, (C) decreases resulting from the establishment or amendment of pools or units from and after the date of this Agreement, and (D) decreases required to allow other working interest owners to make up past underproduction or pipelines to make up past under deliveries;

(ii) obligates Seller to bear the percentage of the costs and expenses relating to the maintenance, development and operation of any well drilled or which could be drilled on such Tract not greater than the working interest for such Tract shown in Exhibit C - Part 1, without increase throughout the duration of the productive life of such well, except (A) as specifically set forth in Exhibit C – Part 1, (B) increases resulting from contribution requirements with respect to defaulting co-owners under applicable operating agreements, and (C) increases to the extent that they are accompanied by a proportionate increase in Seller’s corresponding net revenue interest set forth in Exhibit C – Part 1; and

(iii) is free and clear of all liens, encumbrances and defects

(c) with respect to all other Assets, such title that is good and defensible and is free and clear of all liens, with the exception of Permitted Encumbrances.

Notwithstanding the foregoing, (a) the loss of or reduction of interest in any Tract following the Effective Time due to any election or decision made by Seller in accordance with applicable joint operating agreements as permitted under this Agreement shall not constitute a Title Defect and (b) Lease Expirations shall not be treated as a Title Defect hereunder but will instead be exclusively addressed pursuant to Section 4.13.

Section 4.03 Notice of Title Defects. To assert a claim for a Title Defect, Buyer must notify Seller thereof prior to the expiration of the Title Examination Period. To be effective, such notice (a “Title Defect Notice”) shall be in writing and shall include (a) a detailed description of the alleged Title Defect(s), (b) the Assets affected thereby (each, a “Title Defect Property”), (c) the value of each Title Defect Property (which shall be the Allocated Value thereof), (d) the information upon which the Title Defect(s) are based, and (e) the amount which Buyer reasonably believes to be the Title Defect Amount resulting from the alleged Title Defect(s) and the computations and information upon which Buyer’s belief is based. Upon request, Buyer must provide reasonable supporting documentation for any Title Defect. Subject to Buyer’s rights with respect to any breach by Seller of Section 7.03 and Buyer’s rights under Section 4.08, any matters that may otherwise constitute Title Defects but that are not specifically disclosed to Seller pursuant to a Title Defect Notice delivered to Seller prior to the expiration of the Title Examination Period shall be deemed to have been waived by Buyer, on behalf of itself and its successors and assigns, for all purposes, except as may otherwise be a breach of Seller’s representations and warranties in Section 6.01 and other than Seller’s special warranty of title provided in the assignments delivered at Closing, which will not be affected or diminished by this waiver.

Section 4.04 Remedies for Title Defects. Seller shall have the option, but not the obligation, to attempt to cure any Title Defect on or before Closing (the “Cure End Date”). Buyer agrees to reasonably cooperate with any attempt by Seller to cure any such Title Defect. In the event that any Title Defect is not cured on or before the Cure End Date, then Seller may, at its sole election for each Title Defect:

(a) subject to Section 4.06, adjust the Purchase Price downward in the Final Accounting Statement by an amount (the “Title Defect Amount”) determined in accordance with Section 4.07 for such Title Defect; or

(b) Seller may retain the Title Defect Property and reduce the Purchase Price by an amount equal to the Allocated Value (or portion thereof allocable thereto) of the Title Defect Property, in which event the Parties shall proceed to the Closing, the Title Defect Property shall be retained by Seller and Buyer shall pay to Seller the Purchase Price as so adjusted.

Section 4.05 Title Benefits.

(a) Should either Party discover any Title Benefit on or before the end of the Title Examination Period that would have a Title Benefit Amount greater than $25,000, Seller shall have the right, and Buyer shall have the obligation, to notify the other Party thereof on or before the end of the Title Examination Period, which notice shall include (i) a description of the Title Benefit(s), (ii) the Lease and/or Tract(s) affected (each “Title Benefit Property”), (iii) the Allocated Value of each Title Benefit Property, (iv) documentation sufficient to reasonably support the asserted Title Benefit(s), and (v) the amount by which the asserting Party reasonably believes the Allocated Value of each Title Benefit Property is increased by the alleged Title Benefit(s) and the computations and information upon which such Party’s belief is based.

(b) With respect to each Title Benefit Property reported under Section 4.05(a) for which the Title Benefit Amount is greater than $25,000, (i) if the net revenue interest of the Title Benefit Property is greater than the net revenue interest stated on Exhibit C - Part 1, then the Purchase Price shall be increased by an amount equal to the product of the Allocated Value of the Title Benefit Property multiplied by a fraction, the numerator of which is the actual net revenue interest increase and the denominator of which is the net revenue interest stated on Exhibit C – Part 1, and (iii) if the net revenue interest of the Title Benefit Property is the same as the net revenue interest stated on Exhibit C – Part 1, then the Purchase Price shall be adjusted upward by an amount mutually agreed by Seller and Buyer. The amount by which the Purchase Price is increased pursuant to the preceding sentence of this Section 4.05(b) shall be referred to herein as the “Title Benefit Amount.”

(c) Notwithstanding the foregoing, New Leases will not be treated as a Title Benefit hereunder, but will be addressed exclusively pursuant to Section 4.13.

Section 4.06 Limitations. Notwithstanding anything to the contrary, but excluding any adjustments for Lease Expirations or New Leases, which will be treated as Lease Adjustments in accordance with 4.13, (a) in no event shall there be any adjustments to the Purchase Price or

other remedies available to Buyer for any Title Defect if the sum of all Title Defect Amounts, net of all Title Benefit Amounts, does not exceed one percent of the Purchase Price (the “Title Defect Deductible”), (b) Buyer will only be entitled to one recovery for a matter which constitutes a Title Defect even if such matter breaches another provision of this Agreement, and (c) if the sum of all Title Defect Amounts, net of all Title Benefit Amounts, exceeds the Title Defect Deductible, then any adjustments to the Purchase Price or other remedies provided by Seller pursuant to Section 4.04 shall be applicable only to the portion thereof that exceeds the Title Defect Deductible.

Section 4.07 Title Defect Amount.

(a) The Title Defect Amount resulting from a Title Defect shall be the amount by which the Allocated Value of each 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:

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

(ii) if the Title Defect is an encumbrance 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;

(iii) if the Title Defect represents a discrepancy between (i) the net revenue interest for any well drilled or which could be drilled on such Tract and (ii) the net revenue interest stated in Exhibit C – Part 1, then the Title Defect Amount shall be the product of the Allocated Value of such affected Tract multiplied by a fraction, the numerator of which is the actual net revenue interest and the denominator of which is the net revenue interest stated in Exhibit C – Part 1;

(iv) if the Title Defect represents an obligation, encumbrance 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 Seller 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;

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

(vi) notwithstanding anything to the contrary in this Section 4.07, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon each Title Defect Property shall not exceed the Allocated Value of each Title Defect Property.

(b) If Buyer and Seller are unable to agree upon the Title Defect Amount under this subsection, or the validity of a Title Defect, the Parties shall proceed to the Closing, the Title Defect Property shall be conveyed to the Buyer, the Purchase Price shall be reduced by an amount equal to the Allocated Value of the Title Defect Property otherwise payable at Closing and such amount shall be paid by Buyer into an escrow account established with a federally insured savings or banking institution mutually acceptable to Buyer and Seller pursuant to the terms of an escrow agreement in a form acceptable to the escrow agent and reasonably acceptable to Buyer and Seller. The amount deposited into escrow will remain there until the matter is exclusively and finally resolved by arbitration pursuant to this Section 4.07(b). There shall be a single arbitrator, who shall be a title attorney with at least ten (10) years experience in oil and gas titles involving Texas properties, as selected by mutual agreement of Buyer and Seller within fifteen (15) days after the Closing Date, and absent such agreement, by the Houston office of the American Arbitration Association (the “Title Arbitrator”). The arbitration proceeding shall be held in Austin, 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 twenty (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 rules set forth in Section 4.07(a) and may consider such other matters as in the opinion of the Title Arbitrator are necessary or helpful to make a proper determination. Additionally, the Title Arbitrator may consult with and engage disinterested third parties to advise the arbitrator, including without limitation petroleum engineers. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defect Amounts submitted by either party and may not award damages, interest or penalties to either party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each party shall bear one-half of the costs and expenses of the Title Arbitrator.

Section 4.08 Special Warranty of Title. The assignments delivered to Buyer at Closing will contain a special warranty of title from Seller to Buyer warranting title to the Assets against every Person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under Seller or its Affiliates, but not otherwise.

Section 4.09 Preferential Rights To Purchase. Prior to the Closing, Seller shall use commercially reasonable efforts to comply with all preferential rights to purchase or similar rights relative to the sale of any of the Assets as set forth in Schedule 6.01(v) (the “Subject Preferential Rights”) (provided that Seller shall not be required to provide consideration, incur any expense or undertake obligations to or for the benefit of the holders of the Subject Preferential Rights), and the transactions contemplated by this Agreement are expressly subject to all validly existing and applicable Subject Preferential Rights. In accordance with this Agreement and the applicable

Contracts, Seller shall deliver written notices of the proposed transfer of any Asset subject to the Subject Preferential Rights to the holders of such Subject Preferential Rights. Seller shall promptly notify Buyer if any Subject Preferential Right is exercised or if the requisite period has elapsed without said right having been exercised. If a Third Party who has been offered an interest in any Asset pursuant to a Subject Preferential Right timely elects, prior to the Closing, to purchase such Asset pursuant to the aforesaid offer, and Seller receives written notice of such election prior to Closing, the Asset or part thereof so affected will be eliminated from the Assets, the Purchase Price will be reduced proportionately by the Allocated Value attributable thereto and the Parties shall proceed to the Closing. Otherwise the Assets shall be conveyed to Buyer at Closing subject to any preferential right to purchase or similar right applicable to the transactions that has not been waived. If a Third Party elects to purchase any Asset pursuant to a preferential right to purchase or similar right applicable to the transactions after the Closing Date, Buyer shall be obligated to convey such Asset to such Third Party and shall be entitled to the consideration for the sale of such Asset.

Section 4.10 Consents to Assignment. Prior to Closing, Seller shall use commercially reasonable efforts to obtain all consents set forth in Schedule 6.01(c) (provided that Seller shall not be required to provide consideration, incur any expense or undertake obligations to or for the benefit of the holders of such consents). Seller shall deliver written requests for such consents to the holders thereof. If (a) Seller fails to obtain a consent prior to the Closing, (b) the failure to obtain such consent would cause the assignment of such Asset to Buyer to be void or would materially affect the operation of the Assets, and (c) the requirements of Sections 4.02(a) and (b) are met, then the portion of the Asset subject to such failed consent shall constitute a Title Defect (without giving effect to the Title Defect Deductible) and Seller and Buyer shall have the rights and remedies set forth in Section 4.04 and Section 4.07 with respect thereto.

Section 4.11 Post-Closing Consents. At the Closing, Seller shall execute and deliver to Buyer such assignments of Leases by Governmental Authorities as require consent to assignment that are typically obtained after Closing, on the forms required by such Governmental Authorities having jurisdiction thereof, in addition to the assignment of such Leases pursuant to the Assignment, and Buyer shall pay to Seller, as part of the Purchase Price, the Allocated Value attributable to such Leases. After Closing, Seller and Buyer will cooperate and use their reasonable efforts to obtain all such consents from Governmental Authorities typically obtained after Closing. Until all of such unobtained consents are obtained, Seller shall continue to hold title to the affected Assets as nominee for Buyer. If any such consent is finally denied, then Seller, at its sole option, may elect:

(a) to continue to hold title to the affected Assets as Buyer’s nominee pursuant to the terms described in this Section 4.11 or

(b) to retain the affected Assets subject to such denied consent.

In the event Seller elects the option set forth in Section 4.11(b), then on or before the 10th day following such election, (x) Buyer shall deliver to Seller all proceeds of production (net of all expenses, expenditures, capital expenses, royalties and other costs of operation incurred or paid by Buyer, but excluding mortgage interest and any burdens or encumbrances created by Buyer, all of which shall be released prior to any payment to Seller pursuant to Section 4.11(b)) attributable to the affected Assets from the Effective Time to the date of reassignment of such

Assets from Buyer to Seller, (y) Seller shall reimburse to Buyer the Allocated Value paid to Seller as part of the Purchase Price at the Closing for such affected Assets, and (z) Buyer shall execute any and all conveyances or other instruments necessary or desirable to fully vest title to such Assets in Seller and to otherwise accomplish the foregoing as requested by Seller.

Section 4.12 Tag Along Rights.

(a) Prior to the Closing, Seller shall use commercially reasonably efforts to give notice of the proposed sale and purchase under this Agreement to Third Parties who have Tag Along Rights under applicable joint operating agreements to participate in sales by the Seller of certain Assets. Seller shall timely inform Buyer as to all such Third Parties who waive their Tag Along Rights and all those who indicate a preference to participate.

(b) After Seller has first received an executed confidentiality agreement from a Third Party owning Tag Along Assets, Seller shall promptly supply said Third Party in each case with an executed copy of this Agreement (together with all Exhibits and Schedules hereto), along with written notice that their election to sell their Tag Along Assets must be evidenced by a signed copy of their Tag Along PSA in the form thereof attached hereto as Exhibit E and forwarded to Buyer in time for the Closing.

(c) If a Third Party elects to sell its Tag Along Assets in a simultaneous but separate sale of the Assets at Closing, then Buyer shall be obligated to purchase such Third Party’s Tag Along Assets simultaneous with the Closing.

(d) If Buyer wishes to arrange a purchase or possible purchase of a Third Party’s Tag Along Assets at a date after the Closing Date, then Buyer shall supply Seller with a written waiver in favor of Seller of the Third Party’s Tag Along Rights properly executed by such Third Party in favor of Seller.

Section 4.13 Lease Adjustment. The following adjustments to the Purchase Price (“Lease Adjustments”) shall be made for Seller's purchase of New Leases and Lease Expirations:

(a) The Purchase Price shall be increased by an amount (on a dollar-for-dollar basis and without giving effect to any threshold or deductible amounts provided for elsewhere in this Agreement) equal to the greater of (A) the actual costs incurred by Seller after June 1, 2010 for the purchase of New Leases or (B) the Title Benefit Amount resulting from the New Lease as calculated according to Section 4.05(b) if the New Lease were treated as a Title Benefit (but without regard to the $25,000 individual threshold for Title Benefits). Notwithstanding the foregoing, there will be no upward adjustment to the Purchaser Price for New Leases entered into by Seller after the execution of this Agreement for which Buyer’s approval in accordance with Section 7.04 is not obtained. Buyer and Seller agree that Exhibit A to the Assignment will include the New Leases, regardless of whether they are listed on the Exhibit A – Part 1 to this Agreement.

(b) The Purchase Price shall be decreased by an amount (on a dollar-for-dollar basis and without giving effect to any threshold or deductible amounts provided for elsewhere in this

Agreement) equal to the Title Defect Amount calculated pursuant to Section 4.07(a)(iii) (but without regard to the $25,000 individual threshold for Title Defects) resulting from any Lease Expirations. Notwithstanding the foregoing, there will be no downward adjustment to the Purchase Price for a Lease Expiration where such Lease Expiration could have been cured by Seller prior to the Closing Date by an extension of the underlying Lease but such extension was not obtained due to Buyer’s failure to consent to an extension of the Lease in accordance with Section 7.04.

(c) The Purchase Price shall be increased by an amount (on a dollar-for-dollar basis and without giving effect to any threshold or deductible amounts provided for elsewhere in this Agreement) equal to the cost incurred by Seller in connection with the acquisition of any oil and gas lease after the Effective Time that is not included in the definition of “New Lease” (each an “Interim Lease”) but only to the extent such Interim Lease relates to the Tracts on Pages One, Two or Three of Exhibit C – Part 1, Titled “Allocation of Proven Value”, (the “Proven Tracts”). To the extent that any Interim Lease covers more acreage than is included the Proven Tracts, the amount of the Purchase Price increase will be the amount equal to the cost incurred by Seller in connection with the acquisition of the Interim Lease multiplied a fraction, the numerator of which is the net acres covered by the Interim Lease which are included in any Proven Tract and the denominator of which is the total net acres covered by such Interim Lease.

Section 5.01 Environmental Examination Period.

(a) Commencing on the date hereof and ending October 4, 2010 at 6:00 p.m. Midland, Texas time (the “Environmental Examination Period”), Seller shall, subject to Third Party operator and surface owner approval (which, upon Buyer’s request, Seller shall use commercially reasonable efforts to obtain, provided that Seller shall not be required to provide consideration, incur any expense or undertake obligations to or for the benefit of the holders of such approval rights) and the provisions of Section 7.01 hereof, permit Buyer and/or its representatives, in a reasonable manner, at reasonable times and at Buyer’s sole risk, cost and expense, to conduct reasonable environmental inspections of the Assets; provided, however, that Buyer must make previous arrangements with Seller for each such inspection; and provided, further, that each such inspection shall be limited to a visual inspection of the Seller’s ▇▇▇▇▇ and Leases (although Seller may move dirt or ground coverings at the surface location to obtain such a visual inspection, subject to the requirements of subsection (e) below), it being understood that no soil or water tests, other samplings or borings thereof may be conducted without Seller’s prior consent. If Buyer determines that invasive inspections are warranted, and if Seller declines to consent thereto, Buyer shall have the right to terminate this Agreement, in which case the Deposit shall be paid to Buyer.

(b) Buyer agrees (i) to provide to Seller, upon request, a copy of any portion of any environmental assessments of the Seller’s ▇▇▇▇▇ and Leases conducted by or on behalf of Buyer, including any reports, data and conclusions, to the extent such portion relates to an Environmental Defect described in any Environmental Defect Notice

delivered by Buyer and (ii) to maintain the confidentiality of the information set forth therein, except to the extent disclosure is required under applicable Law.

(c) Each Party agrees that it will not (and will cause its officers not to) use any information obtained pursuant to this Section 5.01 for any purpose unrelated to the consummation of the transactions contemplated by this Agreement.

(d) Buyer shall coordinate its environmental site assessments and physical inspections of Seller’s ▇▇▇▇▇ and Leases with Seller to minimize any inconvenience to or interruption of the conduct of business by Seller insofar as possible without interfering with Buyer’s ability to conduct a thorough examination of the Assets, Buyer shall abide by Seller’s, and any Third Party operator’s, safety rules, regulations and operating policies while conducting its due diligence evaluation of Seller’s ▇▇▇▇▇ and Leases, including any environmental or other inspection or assessment of Seller’s ▇▇▇▇▇ and Leases.

(e) Upon completion of Buyer’s due diligence, Buyer shall at its sole cost and expense and without any cost or expense to Seller or its Affiliates, (i) repair all damage done to Seller’s Assets in connection with Buyer’s due diligence in accordance with recognized industry standards or requirements of Third Party operators, (ii) restore Seller’s Assets to the approximate same or better condition than existed prior to commencement of Buyer’s due diligence, but limited to the full extent of any damage related to Buyer’s due diligence, and (iii) remove all equipment, tools or other property brought onto Seller’s Assets in connection with Buyer’s due diligence. Any disturbance to Seller’s Assets (including, without limitation, any real property, platform or other fixtures associated with such Assets) resulting from Buyer’s due diligence will be promptly corrected by Buyer.

Section 5.02 Environmental Defect. An Asset shall be deemed to have an “Environmental Defect” if Buyer discovers that such Asset is subject to a condition constituting a violation of Environmental Laws with respect to which the Lowest Cost Response therefor is reasonably estimated to require an expenditure in excess of $25,000; provided that an Environmental Defect shall not be deemed to exist with respect to NORM in connection with in-use equipment or with respect to any issues disclosed in Schedule 5.02.

Section 5.03 Notice of Environmental Defects. To assert a claim for an Environmental Defect, Buyer must promptly notify Seller thereof prior to the expiration of the Environmental Examination Period. To be effective, such notice (an “Environmental Defect Notice”) shall be in writing and shall include (a) a detailed description of the alleged Environmental Defect(s), (b) the Assets affected thereby (each, an “Environmental Defect Property”), (c) the value of each Environmental Defect Property (which shall be the Allocated Value thereof), (d) documentation sufficient to reasonably support the asserted Environmental Defect(s), and (e) the amount which Buyer reasonably believes is the Lowest Cost Response to cure the alleged Environmental Defect(s) and the computations and information upon which Buyer’s belief is based. Any matters that may otherwise constitute Environmental Defects but that are not specifically disclosed to Seller pursuant to an Environmental Defect Notice prior to the expiration of the Environmental Examination Period shall be deemed to have been waived by Buyer.

Section 5.04 Remedies for Environmental Defects. Seller shall have the option, but not the obligation, to attempt to cure any Environmental Defect prior to the Cure End Date. In the event that any Environmental Defect is not cured on or before the Cure End Date, then subject to Section 5.05, Seller may, at its sole election for each Environmental Defect:

(a) subject to Section 5.05, adjust the Purchase Price downward by the Lowest Cost Response to cure such Environmental Defect (such adjustment being herein referred to as the “Environmental Defect Amount”), provided if Seller and Buyer are unable to agree on the Environmental Defect Amount prior to the Closing such amount will be determined pursuant to Section 5.06; or

(b) Seller may retain the Environmental Defect Property and reduce the Purchase Price by an amount equal to the Allocated Value (or portion thereof allocable thereto) of each Environmental Defect Property, in which event the Parties shall proceed to the Closing, the Environmental Defect Property shall be retained by Seller and Buyer shall pay to Seller the Purchase Price as so adjusted.

Section 5.05 Limitations. Notwithstanding anything to the contrary, (a) in no event shall there be any adjustments to the Purchase Price or other remedies available to Buyer for any Environmental Defect if the sum of all Environmental Defect Amounts does not exceed $1,000,000 (the “Environmental Defect Deductible”), (b) Buyer will only be entitled to one recovery for a matter which constitutes an Environmental Defect even if such matter breaches another provision of this Agreement, (c) if the sum of all Environmental Defect Amounts exceeds the Environmental Defect Deductible, then any adjustments to the Purchase Price in the Final Accounting Statement or other remedies provided by Seller pursuant to Section 5.04 shall be applicable only to the portion thereof that exceeds the Environmental Defect Deductible, and (d) Section 5.04 (as limited by this Section 5.05) shall, to the fullest extent permitted by applicable Law, but excluding Section 6.01(l) and any remedies described in this Agreement for a breach thereof, be the exclusive right and remedy of Buyer with respect to any Environmental Law, any other environmental matter with respect to the Assets or Seller’s breach of any warranty with respect to Environmental Laws, and Buyer waives any and all other rights, at Law or in equity, with respect thereto.

Section 5.06 Environmental Arbitrator. If Buyer and Seller are unable to agree upon the Environmental Defect Amount, or the validity of an Environmental Defect, the Parties shall proceed to the Closing, the Environmental Defect Property shall be conveyed to the Buyer, the Purchase Price shall be reduced by an amount equal to the Allocated Value of the Environmental Defect Property otherwise payable at Closing and such amount shall be paid by Buyer into an escrow account established with a federally insured savings or banking institution mutually acceptable to Buyer and Seller pursuant to the terms of an escrow agreement in a form acceptable to the escrow agent and reasonably acceptable to Buyer and Seller. The amount deposited into escrow will remain there until the matter is exclusively and finally resolved by arbitration pursuant to this Section 5.06. There shall be a single arbitrator, who shall be an attorney or environmental consultant with at least ten (10) years experience in environmental issues involving Texas oil and gas properties, as selected by mutual agreement of Buyer and Seller within fifteen (15) days after the Closing Date, and absent such agreement, by the Houston office of the American Arbitration Association (the “Environmental Arbitrator”). The arbitration proceeding shall be held in Austin,

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 Environmental Arbitrator’s determination shall be made within twenty (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 Environmental Arbitrator shall be bound by the rules set forth in Article V and may consider such other matters as in the opinion of the Environmental Arbitrator are necessary or helpful to make a proper determination. Additionally, the Environmental Arbitrator may consult with and engage disinterested third parties to advise the arbitrator. The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defect Amounts submitted by either party and may not award damages, interest or penalties to either party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each party shall bear one-half of the costs and expenses of the Environmental Arbitrator.

under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a Third Party against the Indemnitee (a “Claim”), the Indemnitee shall provide its Claim Notice promptly after the Indemnitee has actual knowledge of the Claim and shall enclose a copy of all papers (if any) served with respect to the Claim; provided that the failure of any Indemnitee to give notice of a Claim as provided in this Section 13.11 shall not relieve the Indemnitor of its obligations under this Article XIII except to the extent (and only to the extent of such incremental damages incurred) such failure results in insufficient time being available to permit the Indemnitor to effectively defend against the Claim or otherwise prejudices the Indemnitor’s ability to defend against the Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(c) In the case of a claim for indemnification based upon a Claim, the Indemnitor shall have 30 days from its receipt of the Claim Notice to notify the Indemnitee whether or not it agrees to indemnify and defend the Indemnitee against such Claim under this Article XIII. The Indemnitee is authorized, prior to and during such thirty 30 day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnitor and that is not prejudicial to the Indemnitor.

(d) If the Indemnitor agrees to indemnify the Indemnitee, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Claim. The Indemnitor shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnitor, the Indemnitee agrees to cooperate in contesting any Claim which the Indemnitor elects to contest (provided, however, that the Indemnitee shall not be required to bring any counterclaim or cross-complaint against any Person). The Indemnitee may participate in, but not control, at its sole cost and expense, any defense or settlement of any Claim controlled by the Indemnitor pursuant to this Section 13.11. An Indemnitor shall not, without the written consent of the Indemnitee, such consent not to be unreasonably withheld or delayed, settle any Claim or consent to the entry of any judgment with respect thereto that (i) does not result in a final resolution of the Indemnitee’s Liability with respect to the Claim (including, in the case of a settlement, an unconditional written release of the Indemnitee from all Liability in respect of such Claim) or (ii) may materially and adversely affect the Indemnitee (other than as a result of money damages covered by the indemnity).

(e) If the Indemnitor does not agree to indemnify the Indemnitee within the 30 day period specified in Section 13.11(c), fails to give notice to the Indemnitee within such 30 day period regarding its election or if the Indemnitor agrees to indemnify, but fails to diligently defend or settle the Claim, then the Indemnitee shall have the right to defend against the Claim (at the sole cost and expense of the Indemnitor, if the Indemnitee is entitled to indemnification hereunder), with counsel of the Indemnitee’s choosing; provided, however, that the Indemnitee shall make no settlement, compromise, admission or acknowledgment that would give rise to Liability on the part of any

Indemnitor without the prior written consent of such Indemnitor, which consent shall not be unreasonably withheld, conditioned or delayed.

(f) In the case of a claim for indemnification not based upon a Claim, the Indemnitor shall have 30 days from its receipt of the Claim Notice to (i) cure the damages complained of, (ii) agree to indemnify the Indemnitee for such Damages, or (iii) dispute the claim for such damages. If such Indemnitor does not respond to such Claim Notice within such 30 day period, such Person will be deemed to dispute the claim for damages.

(a) Except as set forth in Sections 14.02(b) and (c), Buyer hereby assumes all risk of loss with respect to, and any change in the condition of, the Assets from the Effective Time until Closing, including for production of Hydrocarbons through normal depletion (including the watering-out of any well, collapsed casing or sand infiltration of any well), the depreciation of personal property due to ordinary wear and tear or any diminution of value resulting from industry-wide or regional fluctuation in markets or economies.

(b) If, after the Effective Time and prior to the Closing, any part of the Assets shall be damaged or destroyed by fire or other casualty or if any part of the Assets shall be taken in condemnation, under the right of eminent domain or if proceedings for such purposes shall be pending or threatened, and the loss as a result of such individual casualty or taking exceeds twenty percent (20%) of the Purchase Price, Buyer shall not be required to close. Should Buyer elect to close, Seller and Buyer shall agree, by written notice prior to Closing, either (i) to cause the Assets affected by any casualty or taking to be repaired or restored to at least its condition prior to such casualty, at Seller’s sole cost, as promptly as reasonably practicable (which work may extend after the Closing Date), (ii) to treat such casualty or taking as a Title Defect with respect to the affected Asset or Assets under Section 4.04 (but without regard to the limitations of Section 4.06).

(c) If, after the date of this Agreement but prior to the Closing Date, any portion of the Assets is destroyed by fire or other casualty or is taken in condemnation or under right of eminent domain, and the loss as a result of such individual casualty or taking is twenty percent (20%) or less of the Purchase Price, Buyer shall nevertheless be required to close and Seller shall, at Closing, reduce the Purchase Price in an amount equal to the allocated value of the Asset affected by the casualty or taking. If Buyer agrees, Seller shall in lieu of a Purchase Price reduction contemplated above, pay to Buyer and shall assign, transfer and set over to Buyer or subrogate Buyer to all of Seller’s right, title and interest (if any) in insurance claims, unpaid awards, and other rights against Third Parties (other than Affiliates of Seller and its and their directors, officers, employees and agents) arising out of the casualty or taking.
