Section 4.01 Examination Period.

After the execution of this Agreement until 5:00 p.m., local time in Midland, Texas on December 7, 2007 (the “Examination Period”), at Buyer’s sole cost and risk, Seller

(a) shall permit Buyer and/or its representatives to examine, at reasonable times during normal business days and hours and in Seller’s offices, all abstracts of title, title opinions, title files, ownership maps, lease, well and division order files, assignments, operating and accounting records and all Surface Agreements, Permits, Contracts, and other agreements pertaining to the Assets insofar as same may now be in existence and in the possession or control of Seller, subject to such restrictions upon disclosure as may exist under confidentiality or other agreements binding upon Seller or such data; and

5

(b) shall provide access to the Assets in order for Buyer to conduct a Phase I environmental site assessment, as that term is defined by the Association of Standards, Tests and Measurements. Except as otherwise required by law, such Phase I environmental site assessment, and all reports, drafts, data, and analyses relating thereto shall remain strictly confidential and Buyer shall not disclose the same to any third party without the prior written consent of Seller which shall not be unreasonably withheld.

Section 4.02 Title Matters.

(a) Definition of Defensible Title.

(i) As used in this Agreement, the term “Defensible Title” shall mean, subject to Permitted Encumbrances, that title of Seller evidencing its ownership of the Assets which is filed and deducible of record (to the extent constituting real property), including the federal and state records for federal and state leases (as applicable), and is free from doubt such that a prudent person engaged in the business of ownership, development, and operation of producing oil and gas properties, with knowledge of all of the facts and their legal effect, would be willing to accept the same;

(ii) With respect to each Well or Well location shown on Exhibit C, title thereto which entitles Seller to receive not less than the percentage set forth in Exhibit C as Seller’s Net Revenue Interest of all Hydrocarbons produced, saved, and marketed from such Well or Well location as to the currently producing interval in each such Well and as to the interval or zone identified on Exhibit C with respect to each such non-producing Well or Well location, all without reduction, suspension or termination of such interest throughout the productive life of such Well or Well location, except as specifically set forth in such Exhibit C;

(iii) With respect to each Well or Well location shown on Exhibit C, obligates Seller to bear not greater than the percentage set forth in Exhibit C as Seller’s Working Interest of the cost and expenses relating the maintenance, development, and operation of such Well or Well location as to the currently producing interval in each such Well and as to the interval or zone identified in Exhibit C with respect to each non-producing Well or Well location, all without increase throughout the productive life of such Well or Well location, except as specifically set forth in Exhibit C, and except to the extent such increase is accompanied by a proportionate increase in the Net Revenue Interest of such Well or Well location; and

(iv) Entitles Seller to hold title to the interest in the Subject Interests, Leases, and Xxxxx set forth in Exhibit C free and clear of all liens and encumbrances, obligations or defects (except for Permitted Encumbrances, as defined in this Section 4.02(h), below).

6

(b) Definition of Title Defect. As used in this Agreement, the term “Title Defect” shall mean any defect which alone, or in conjunction with other defects, causes Seller not to have Defensible Title to the Subject Interest, Lease, or Well.

(c) Title Adjustment. There shall not exist at Closing hereunder any uncured Title Defects asserted by Buyer except where:

(i) adjustments therefor will be made to the Purchase Price payable hereunder in accordance with the provisions of this Agreement;

(ii) Buyer has elected to attempt to cure any such Title Defect pursuant to Section 4.04(g); or

(iii) Buyer has elected to waive any such Title Defects.

(d) “Defect Value” shall be determined based upon the criteria set forth below:

(i) If the Title Defect is a lien upon any such Subject Interest, Lease or Well, the Title Defect Value is the amount necessary to be paid to remove the lien from the affected Subject Interest, Lease or Well.

(ii) If the Title Defect asserted is that the Net Revenue Interest (as that term is defined in Section 4.02(f), below) attributable to any Lease or Well is less than that stated in Exhibit C, then the Title Defect Value is the product of the Allocated Value (as that term is defined in Section 4.02(e) below) attributed to such Lease or Well, multiplied by a fraction, the numerator of which is the difference between the Net Revenue Interest applicable thereto set forth in Exhibit C and the actual Net Revenue Interest, as determined by Buyer, and the denominator of which is the applicable Net Revenue Interest stated in Exhibit C.

(iii) If the Title Defect represents an obligation, encumbrance, burden or charge upon the affected Lease or Well [including any increase in Working Interest (as that term is defined in Section 4.02(g), below) for which there is not a proportionate increase in Net Revenue Interest] for which the economic detriment to Buyer is unliquidated, the amount of the Title Defect Value shall be mutually determined by Buyer and Seller by taking into account the Allocated Value of the affected Lease or Well, the portion of the Lease or Well affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the remaining life of the affected Lease or Well, and the respective Title Defect Values placed upon this Title Defect by Buyer and Seller.

7

(iv) If a Title Defect is not in effect, or does not adversely affect a Lease or Well throughout the entire productive life of such Lease or Well, such fact shall be taken into account in determining the Title Defect Value.

(v) The Title Defect Value of each Title Defect shall be determined without duplication of any costs or losses included in the Title Defect Value of any other Title Defect hereunder.

(vi) Notwithstanding anything herein to the contrary, in no event shall a Title Defect Value exceed the Allocated Value of the Lease(s), Well(s), or other Assets affected thereby; and

(vii) Such other factors as are reasonably necessary to make a proper evaluation.

(e) “Allocated Value” attributed to each Lease or Well shall be that which is set forth on Exhibit F to this Agreement.

(f) “Net Revenue Interest” shall mean Seller’s interest in and to all production of Hydrocarbons saved, produced and sold or which can be produced and sold from any Well or Lease after giving effect to all valid lessor’s royalties, overriding royalties, production payments, carried interest, liens, and other encumbrances or charges against production therefrom.

(g) “Working Interest” shall mean with respect to the Leases and the Xxxxx, Seller’s interest in and to the full and entire leasehold estate created under and by virtue of the Leases and all rights and obligations of every kind and character appurtenant thereto or arising therefrom, without regard to any valid lessor’s royalty, overriding royalties, production payments, carried interest, liens, or other encumbrances or charges against production therefrom insofar as such interest in said leasehold estate is burdened with the obligation to bear and pay costs of operations.

(h) “Permitted Encumbrances” shall mean:

(i) any (x) undetermined or inchoate liens or charges constituting or securing the payment of expenses that were incurred incidental to the maintenance, development, production or operation of the Assets or for the purpose of developing, producing or processing Hydrocarbons therefrom or therein, and (y) materialman’s, mechanics’, repairman’s, employees’, contractors’, operators’ liens or other similar liens or charges for liquidated amounts arising in the ordinary course of business: (A) that Seller has agreed to retain or pay pursuant to the terms hereof, or (B) for which Seller is responsible for paying or releasing at the Closing.

8

(ii) any liens for taxes and assessments not yet delinquent or, if delinquent, that are being contested in good faith in the ordinary course of business and for which Seller has agreed to pay pursuant to the terms hereof or which have been prorated pursuant to the terms hereof.

(iii) the terms, conditions, restrictions, exceptions, reservations, limitations and other matters contained in (including any liens or security interests created by law or reserved in oil and gas leases or royalty, bonus or rental, or created to secure compliance with the terms of) the Leases, Contracts or Surface Agreements; provided, that, such matters do not operate to (x) reduce the Net Revenue Interest of Seller in any Lease or Well as reflected in Exhibit C hereto or (y) increase the proportionate share of costs and expenses of leasehold operations attributable to or to be borne by the Working Interest of Seller with respect to any Lease or Well as reflected in Exhibit C hereto, unless there is a proportionate increase in Seller’s applicable Net Revenue Interest;

(iv) any (x) easements, rights-of-way, servitudes, permits, surface leases and other rights in respect of surface operations, pipelines, grazing, hunting, lodging, canals, ditches, reservoirs or the like, and (y) easements for streets, alleys, highways, pipelines, telephone lines, power lines, railways, and other similar rights-of-way on, over or in respect of property owned or leased by Seller, or over which Seller owns rights-of-way, easements, permits or licenses, in either case which do not materially affect the ownership and operation of the Assets affected or the value thereof;

(v) all royalties, overriding royalties, net profits interests, carried interests, production payments, reversionary interests and other burdens on or deductions from the proceeds of production created or in existence as of the Effective Time, which recorded or unrecorded, that do not operate to reduce the Net Revenue Interests of Seller set forth on Exhibit C, or increase the Working Interests of Seller set forth on Exhibit C without a corresponding increase in its Net Revenue Interests;

(vi) all rights to consent by, required notices to, filings with, or other actions by Governmental Authorities in connection with the sale, transfer or conveyance of the Assets that are customarily obtained subsequent to such sale or conveyance;

(vii) rights reserved to or vested in any Governmental Authority to control or regulate any of the Leases or units included in the Assets and the applicable laws, rules, and regulations of any such Governmental Authority;

9

(ix) any Title Defects Buyer may have expressly waived;

(x) preferential rights to purchase or similar agreements, subject to Section 4.05A;

(xi) required third party consents to assignment or similar agreements with respect to which (a) waivers or consents are obtained from the appropriate parties for the transaction contemplated hereby or (b) required notices have been given for the transaction contemplated hereby to the holders of such rights and the appropriate period for asserting such rights has expired without an exercise of such rights;

(xii) liens and security interests which are released at Closing pursuant to Section 10.07; and

(xiii) that certain net profits overriding royalty interest conveyed by Xxxxxxx Energy I, Ltd. to TCW Energy Funds X Holdings, L.P. pursuant to that certain Conveyance of Net Profits Overriding Royalty Interest dated as of February 16, 2006, as amended by First Supplement dated effective as of July 1, 2006, and by Second Supplement dated effective as of November 1, 2007 (the “TCW Net Profits Interest”), which is reassigned by TCW Energy Funds X and XIV Holdings, L.P. to Xxxxxxx Energy I, Ltd. at or before Closing pursuant to Section 10.07.

(i) “Governmental Authority” shall mean, as to any given Asset, the United States and the state, county, parish, city and political subdivisions in which such Asset is located and that exercises jurisdiction over such Asset, and any agency, department, board or instrumentality thereof that exercises jurisdiction over such Asset.

Section 4.03 Title Review. At its sole cost and expense, Buyer shall commence and diligently pursue such examination of title to the Assets as Buyer desires and may continue such examination through the Closing Date, as defined in Section 10.01, below.

Section 4.04 Determination of Title Defects and the Defect Values.

(a) Buyer shall notify Seller in writing of any claimed Title Defect on or before December 7, 2007 (the “Title Defects Notice”). The Title Defects Notice shall:

(i) set forth in reasonable detail the Leases or Xxxxx with respect to which a claimed Title Defect is made,

(ii) the nature of such claimed Title Defect, and

10

(iii) Buyer’s proposed calculation of the value of each claimed Title Defect (the “Defect Value Adjustment”).

Any Title Defect that is not identified in the Title Defect Notice shall thereafter be forever waived and expressly assumed by Buyer, except for any Title Defect that constitutes a breach of Seller’s special warranty of title contained in the form of Assignment attached hereto as Exhibit G. Closing shall occur notwithstanding the Title Defects identified by Buyer, subject to Section 10.03.

(b) Within five (5) days after Seller’s receipt of the Title Defects Notice, Seller shall give written counter-notice (“Seller’s Notice”) to Buyer that it

(i) intends to correct or cure any or all of the asserted Title Defects,

(ii) agrees with such Title Defect and rather than correcting the Title Defect agrees to the Defect Value Adjustment,

(iii) it agrees with the Title Defect, does not want to correct the Title Defect, but does not agree to the amount of the Defect Value Adjustment, or

(iv) it disagrees that the asserted Title Defect exists.

(c) If Seller’s Notice expresses the intent to cure any of the Title Defects, it shall have a period of ten days from the receipt of the Title Defect Notice (the “Cure Period”) to correct such asserted Title Defect at its own expense. If the Title Defect has not been cured within the Cure Period, the amount of the Defect Value Adjustment shall be credited by Buyer as part of the Purchase Price Adjustment, pursuant to Section 10.03, below, and the Title Defect shall be assumed by Buyer.

(d) If Seller’s Notice states that the Seller disagrees that there is a Title Defect and/or if the Defect Value Adjustment cannot be agreed upon, then the existence of the Title Defect and/or Defect Value Adjustment, if any, will be determined by arbitration pursuant to Article XV hereof.

(e) The failure of Seller to deliver Seller’s Notice within the time prescribed shall be deemed to be:

(i) an acquiescence to the existence of such Title Defect,

(ii) an agreement to the amount of the Defect Value Adjustment, and

(iii) an agreement that the Purchase Price shall be adjusted by the Defect Value Adjustment, pursuant to Section 10.03, below.

(f) If the existence of a Title Defect or the amount of the Defect Value Adjustment is to be determined by arbitration pursuant to Article XV hereof, the Purchase Price,

11

shall not be reduced by the amount of the Defect Value Adjustment Buyer proposed for that Title Defect on the Closing Date, but until the conclusion of the arbitration proceeding such amount shall be held in escrow pursuant to a mutually acceptable escrow agreement to be negotiated by the Parties. If Buyer should prevail in the arbitration, Seller shall, within five (5) days after the arbitration decision, cause the remission of the full or partial amount, of said Defect Value Adjustment, as applicable, to Buyer, as was determined in such decision.

(g) Subject to Section 4.04 (f), if Seller is unable or chooses not to cure a Title Defect as specified above, Buyer shall have the right but not the obligation to remove the subject Lease or defective portion on which there is a Title Defect from the transaction contemplated by this Agreement and reduce the Purchase Price in accordance with Section 10.03, below; provided, however, that Buyer may elect to attempt to cure any such remaining defect itself for a period of 180 days from the Final Settlement Date. If Buyer so elects to attempt to cure, then it shall be permitted to withhold from the adjusted Purchase Price the value of the leasehold acres attributable to such defects in accordance with Section 10.03, below. If within such 180-day period the defect is cured by Buyer, or not cured but Buyer elects to retain such interest, then Buyer shall remit to Sellers the value of the defect so withheld.

Section 4.05 Suspense Funds Held by Seller. Seller agrees to convey to Buyer and Buyer agrees to receive all suspense held by Seller, if any, as of the Effective Time, for the benefit of royalty, overriding royalty and working interest owners attributable to the Leases or Xxxxx, except and excluding minimum suspense funds and suspense accounts with a negative balance, the amount of such funds to be adjusted with respect to the suspense funds received and disbursed by Seller. Buyer will defend, indemnify and hold Seller harmless from and against any future liability associated with such funds.

Section 4.05A Preferential Rights to Purchase and Consents. Seller shall use its reasonable efforts, but without any obligation to incur any cost or expense in connection therewith (other than de minimis amounts), to comply with all preferential right to purchase provisions relative to any Asset prior to the Closing. Prior to the Closing, Seller shall notify Buyer of the existence of any preferential purchase rights, if any preferential purchase rights are exercised or if the requisite period has elapsed without said rights having been exercised. If a third party who has been offered an interest in any Asset pursuant to a preferential right to purchase elects prior to the Closing to purchase all or part of such Asset pursuant to the aforesaid offer, the interest or part thereof so affected will be eliminated from the Assets and the Purchase Price shall be reduced by the Allocated Value of such Asset. Otherwise, the interest offered as aforesaid shall be conveyed to Buyer at the Closing subject to any preferential right to purchase of any third party for which notice has been given but the time period for response by the holder of such preferential right extends beyond the Closing and Buyer shall assume all duties, obligations and liabilities arising from such preferential right to purchase. Without limiting the foregoing, if any such third party elects to purchase all or a part of an interest in any Asset subject to a preferential right to purchase after the Closing Date, Buyer shall be obligated to convey said interest to such third party and shall be entitled to the consideration for the sale of such interest or part thereof.

12

Seller shall use all reasonable efforts to obtain all necessary consents from third parties to assign the Assets prior to Closing (other than governmental approvals that are customarily obtained after Closing) and Buyer shall assist Seller with such efforts.

Section 4.06 Environmental Matters.

(a) Adverse Environmental Condition. “Adverse Environmental Condition” means

(i) any contamination or condition exceeding currently allowed regulatory limits and not otherwise permanently authorized by permit or law, resulting from any discharge, release, disposal, production, storage, treatment, or any other activities on, in or from any Lease or Well, or the migration or transportation from other lands to any Lease or Well, prior to the Effective Time, of any wastes, pollutants, contaminants, Hazardous Substances or other materials or substances subject to any state or federal law or regulation relating to the protection of the environment, including, but not limited to, the Clean Air Act, the Comprehensive Environmental Response, Compensation and Liability Substance Control Act, the Hazardous Waste and Solid Waste Amendments Act of 1984, the Superfund Amendments and Reauthorization Act of 1986, the Hazardous Materials Transportation Act, the Clean Water Act, the National Environmental Policy Act, the Endangered Species Act, the Fish and Wildlife Coordination Act, the National Historic Preservation Act, and the Oil Pollution Act of 1990, as well as any state and local regulation or law governing the same, similar or related matters (“Environmental Laws”), and

(ii) any such contamination or condition temporarily authorized by permit, fee agreement or other arrangement.

(b) Environmental Assessment. At its sole cost and expense, Buyer shall commence and diligently pursue a Phase I environmental site assessment of the Assets as Buyer desires and may continue such examination through the Closing Date.

Buyer shall consult with Seller before conducting any work comprising Buyer’s environmental site assessment of the Assets, shall perform all such work in a safe and workmanlike manner so as not to unreasonably interfere with Seller’s operations, and will comply with all applicable laws, rules and regulations. With respect to any samples taken in connection with Buyer’s environmental site assessment of the Assets, Buyer shall take split samples, providing one of each such sample,

13

properly labeled and identified, to Seller. BUYER HEREBY AGREES TO RELEASE, DEFEND, INDEMNIFY AND HOLD HARMLESS EACH PARTY SELLER AND THEIR RESPECTIVE PARTNERS, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, REPRESENTATIVES, MEMBERS, SHAREHOLDERS, AFFILIATES, HEIRS, SUCCESSORS AND ASSIGNS, FROM AND AGAINST ALL CLAIMS, LOSSES, DAMAGES, COSTS, EXPENSES, CAUSES OF ACTION AND JUDGMENTS OF ANY KIND OR CHARACTER (INCLUDING THOSE RESULTING FROM SELLER’S SOLE, JOINT, COMPARATIVE OR CONCURRENT NEGLIGENCE OR STRICT LIABILITY) ARISING OUT OF OR RELATING TO BUYER’S ENVIRONMENTAL SITE ASSESSMENT OF THE ASSETS. Notwithstanding the foregoing and assuming that Buyer complies with the notice requirements of this Section 4.06, prior to Closing Buyer shall have no indemnity obligation to Seller with respect to Buyer’s discovery of information that may lead to Claims arising from the condition of the Assets prior to Buyer’s Environmental Review.

(c) Notice of Adverse Environmental Condition. Buyer shall notify Seller in writing of any claimed Adverse Environmental Condition (“Environmental Defect”) on or before December 7, 2007 (“Environmental Defects Notice”). The Environmental Defects Notice shall

(i) set forth in reasonable detail the Well and/or Lease with respect to which a claimed Adverse Environmental Condition is made,

(ii) the nature of such claimed Adverse Environmental Condition, and

(iii) Buyer’s proposed calculation of the cost to remediate each claimed Adverse Environmental Condition (“Remediation Value Adjustment”).

(d) Determination of Adverse Environmental Conditions and Remediation Values. Within five (5) days after Seller’s receipt of the Environmental Defects Notice, Seller shall give written counter notice (“Seller’s Environmental Notice”) to Buyer that it

(i) intends to correct the asserted Environmental Defect,

(ii) agrees with the Adverse Environmental Condition and rather than correcting the Adverse Environmental Condition, agrees to the Remediation Value Adjustment as an adjustment to the Purchase Price, payable under this Agreement, or

(iii) it agrees with the Adverse Environmental Condition, does not want to correct the Adverse Environmental Condition, but does not agree to the amount of the Remediation Value Adjustment, or

14

(iv) it disagrees that the asserted Adverse Environmental Condition for that Lease or Well exists, or

(v) agrees with the asserted Adverse Environmental Condition for that Lease or Well, but because the Remediation Value Adjustment is greater than the Allocated Value assigned to the Lease or Well on Exhibit F, Seller elects to exclude the property from the sale and reduce the Purchase Price by the full Allocated Value thereof.

(1) If Seller’s Environmental Notice expresses the intent to cure the Environmental Defect, it shall have a period of five (5) days from the receipt of the Environmental Defect Notice (the “Cure Period”) to correct such asserted Environmental Defect at its own expense. If the Environmental Defect has not been cured within the Cure Period, the amount of the Remediation Value Adjustment shall be credited to Buyer at Closing as a part of the Purchase Price Adjustment to be made pursuant to Section 10.03 hereof and the Environmental Defect shall be assumed by Buyer at Closing.

(2) If Seller’s Environmental Notice states that the Seller disagrees that there is an Environmental Defect and/or Remediation Value Adjustment cannot be agreed upon, then the existence of the Environmental Defect and/or Remediation Value Adjustment, if any, will be determined by arbitration pursuant to Article XV hereof.

(3) The failure of Seller to deliver Seller’s Environmental Notice within the time prescribed shall be deemed to be:

(i) an acquiescence to the existence of such Environmental Defect,

(ii) an agreement to the amount of the Remediation Value Adjustment, and

(iii) an agreement that the Purchase Price, under this Agreement, shall be adjusted by the Remediation Value Adjustment pursuant to Section 10.03 hereof.

(4) If the existence of an Environmental Defect or the amount of Remediation Value Adjustment is to be determined by arbitration pursuant to Article XV hereof, the Purchase Price to be paid by Buyer to Seller, under this Agreement, shall not be reduced on the Closing Date by the amount of the Remediation Value Adjustment that Buyer has proposed be made, but until the conclusion of the arbitration proceeding such amount shall be held in escrow

15

pursuant to a mutually acceptable escrow agreement to be negotiated by the Parties. If Buyer should prevail in the arbitration, Seller shall, within five (5) days, cause to be refunded any portion or all of such Remediation Value Adjustment Reduction to Buyer in the amount determined by the arbitration decision.

(e) Exclusive Remedy. Subject to Section 16.01(a), this Section 4.06 shall be the exclusive right and remedy of Buyer with respect to any Environmental Defect.

Section 4.07 Limitation of Remedies for Title and Environmental Defects. Notwithstanding anything to the contrary contained in Article IV hereof, (a) if the Defect Value of a given Title Defect or the Remediation Value Adjustment of a given Environmental Defect does not exceed $25,000, as determined pursuant to Article IV or Article XV hereof, then no adjustment to the Purchase Price shall be made for such Title Defect or Environmental Defect and no such Title Defect or Environmental Defect shall be counted toward the Aggregate Deductible, (b) if the aggregate net adjustment to the Purchase Price determined in accordance with this Agreement for all Title Defects and Environmental Defects does not exceed 2% of the Purchase Price (the “Aggregate Deductible”), then no adjustment to the Purchase Price shall be made therefor, and (c) if the aggregate net adjustment to the Purchase Price determined in accordance with this Agreement for all Title Defects and Environmental Defects does exceed the Aggregate Deductible, then the Purchase Price shall only be adjusted by the amount of such excess. If Seller elects to retain any Assets related to an Environment Defect under Section 4.06, the Environmental Defect Value with respect to all such Environmental Defects shall not be counted towards the Aggregate Deductible.
