There is expressly excluded from the Assets to be conveyed pursuant hereto, and each Seller shall except, reserve, and retain to itself, severally according to its respective ownership thereof and not jointly, the following properties and assets: (i) all corporate, financial, legal, and tax records of each Seller; (ii) all deposits, cash, checks in process of collection, cash equivalents, accounts receivable and funds attributable to the Assets for the period prior to the Effective Date; (iii) all rights, interests, and claims that Sellers may have under any policy of insurance or indemnity, surety bond, or any insurance or condemnation proceeds or recoveries from third persons relating to property damage or Casualty Loss affecting the Assets occurring prior to the Effective Date; (iv) all claims, whether in contract, in tort, or arising by operation of law, and whether asserted or unasserted as of the Closing Date, that Sellers may have against any person arising out of acts, omissions, or events, or injury to or death of persons or loss or destruction of or damage to property, relating in any way to, the Assets that occurred prior to the Effective Date; provided, however, that no such claim may be settled, compromised, or otherwise resolved in a manner that results in an obligation borne by Purchaser or the Assets on and after the Effective Date without the prior written consent of Purchaser, which shall not to be unreasonably withheld Page 10 or delayed; (v) all exchange traded futures contracts and over-the-counter derivative contracts of any Seller as to which such Seller has an open position as of the Effective Date; (vi) any and all rights to use the names, marks, trade dress or insignia of any Seller, and all of the intellectual property of each Seller, including, without limitation, proprietary or licensed computer software; patents; trade secrets; copyrights; all geological and geophysical information and data (including, without limitation, conventional two-dimensional and three-dimensional seismic data) that image, cover, or otherwise pertain in any way to lands and/or subsurface intervals not included in the Assets, or Technical Data as to which the sale or disclosure of such data is restricted or prohibited by agreement with third parties, and Sellers' proprietary interpretations of any of the foregoing; economic analyses; and pricing forecasts; (vii) all amounts due or payable to any Seller as adjustments to insurance premiums related to the Assets for periods prior to the Effective Date; (viii) all claims of any Seller for any tax refunds and loss carry-forwards and carry-backs with respect to any taxes relating to the Assets for periods prior to the Effective Date; (ix) all audit rights and all amounts due or payable to any Seller as refunds, adjustments, or settlements of disputes arising under the Properties or the Existing Contracts for periods prior to the Effective Date; all inventories of pipe, equipment and other Personal Property not currently in use or allocated for use in connection with the Assets, and the surface location(s) where such items of property are located; (xi) all rights to drill future Hydrocarbon wells on and rights to earn additional interests in lands and subsurface intervals covered by the Leases, as well as other leases and lands, not included within the Assets under the terms of that certain Farmout Agreement dated May 5, 1995, as amended and/or extended, by and between Sue-Ann Production Company and Douglas Sartoris; (xii) the overriding royalty interests reserved by DSX in Article II of the General Assignment; and (xiii) all other interests, rights, property, and assets of Sellers not located on or used in connection with the Assets or otherwise specifically included in the definition of the Assets. 2. SALE AND PURCHASE 2.1 Purchase and Sale. At the Closing, Sellers shall sell, assign, transfer, and convey to Purchaser, and Purchaser shall purchase and pay for, the Assets, and Purchaser shall also assume the Assumed Obligations as set forth in Section 13.3.4. 2.2 Purchase Price. The purchase price to be paid by Purchaser to Sellers with respect to the Assets (the "Purchase Price") shall equal the product obtained by multiplying (i) the aggregate Allocation Percentages of DSX, KEBO, and those Possible Sellers who execute and return to Purchaser signature pages for this Agreement in a timely manner in accordance with Section 1.1.2, by (ii) ONE HUNDRED MILLION AND NO/100 Dollars U.S. ($100,000,000.00) (the "Full Interest Purchase Price"). If all Possible Sellers execute and return to Purchaser signature pages for this Agreement in a timely manner in accordance with Section 1.1.2, the Purchase Price shall equal the Full Interest Purchase Price. To the extent that the Purchase Price is less than the Full Interest Purchase Price, such shortfall shall not be taken into account in determining whether (y) the Deductible (as defined below) has been met for purposes of Section 3.5.2 or Section 5.5.2, or (z) the Termination Threshold (as defined below) has been met for purposes of Section 3.8. The amount of the Purchase Price is set in consideration of Purchaser's assumption of the Assumed Obligations as set forth in Section 13.3.4. Page 11 2.3 Performance Deposit. 2.3.1 If Possible Sellers having, in the aggregate, Allocation Percentages equal to or greater than ninety-two percent (92%) execute and return to Purchaser signature pages for this Agreement in accordance with Section 1.1.2, Purchaser, as evidence of Purchaser's good faith intention to consummate the transactions contemplated hereby, shall tender to DSX, on behalf of Sellers, no later than 6:00 p.m., Central Daylight Time, on the second Business Day after the Participation Date, a cash performance deposit in the amount of TWO MILLION FIVE HUNDRED THOUSAND AND NO/100 Dollars U.S. ($2,500,000.00) (the "Performance Deposit"). If Purchaser fails to tender to Sellers the Performance Deposit in a timely manner as provided in the immediately preceding sentence of this Section 2.3.1, Sellers shall have the right to terminate this Agreement. If this Agreement is thus terminated by Sellers, neither Sellers nor Purchaser shall have any further obligation or liability to the other Party under this Agreement or otherwise in connection with the transactions contemplated herein, subject, however, to the terms of Section 14.2. 2.3.2 If Sellers terminate this Agreement in accordance with Section 14.1.2 or Section 14.1.5 hereof, Sellers shall retain the Performance Deposit as liquidated damages; provided that nothing contained herein shall prohibit Purchaser from contesting the basis for Sellers' decision to terminate and seeking recovery of such Performance Deposit through any legal means available to it. The Parties agree that the Performance Deposit is a reasonable sum considering all the circumstances existing on the date of this Agreement, including the relationship of the sum to the range of harm to Sellers that reasonably could be anticipated and the anticipation that proof of actual damages would be costly or inconvenient. If this Agreement is otherwise terminated for any reason by either Sellers or Purchaser pursuant to the terms thereof, the Performance Deposit shall be returned to Purchaser, except to the extent otherwise provided in Section 8.10. In the event the transactions contemplated herein close, the Performance Deposit shall be retained by Sellers and credited against the Purchase Price payable by Purchaser hereunder. 2.4 Determination of Adjusted Purchase Price. The net purchase price for the Assets (the "Adjusted Purchase Price") shall be determined as follows: 2.4.1 The Purchase Price; 2.4.2 Plus the amount of the value of all merchantable Hydrocarbons produced from or allocable to the Properties existing in pipelines, storage tanks, or other processing or storage facilities (including, without limitation, unsold inventories of plant products owned by Sellers if any) upstream of the delivery points to the relevant purchasers as of the Effective Date, the value to be based on the contract price applicable to such Hydrocarbons in effect as of the Effective Date (or the market value, if there is no contract price, in effect as of the Effective Date), less amounts payable as royalties, overriding royalties, and other, similar burdens upon such Hydrocarbons; Page 12 2.4.3 Plus the amount of all actual expenditures made or prepaid by Sellers that are incurred in connection with the Assets which are attributable to periods on and after the Effective Date through the Closing Date, including, without limitation: rentals, shut-in well payments, and other lease maintenance payments; operating costs; premiums on insurance policies allocable to the period on and after the Effective Date through the Closing Date; capital costs (including, without limitation, all drilling costs, completion costs, acreage expenditures, acquisition expenditures, seismic expenditures, and waterflood expenditures); and the direct, overhead, and other charges and expenses (including, without limitation, the salaries, wages, and personal expenses of technical employees of Sellers directly employed on the Assets, to the extent that such charges are permitted as direct charges to the joint account under the terms of the applicable joint operating agreements) billed to Sellers by the operator or operators (including, without limitation, KEBO or its Affiliates) of the Assets under applicable operating agreements (or if KEBO or its Affiliate is the operator in the absence of an operating agreement, the charges provided in Section 8.3 hereof), including, without limitation, unreimbursed expenses paid by Sellers on behalf of third parties to which Sellers are entitled to reimbursement under such operating agreements; 2.4.4 Plus an amount equal to upward adjustments for Interest Additions determined in accordance with Section 3.7, and the amount of any interest accrued on the Purchase Price pursuant to Section 12.2; 2.4.5 Plus the total amount of any Property Taxes (as defined below) paid by any Seller for its or another Seller's accounts, relating to the Assets and attributable to any period of time on and after the Effective Date, as further provided for in Sections 15.1 and 15.2 and to the extent same are not included under Section 2.4.3 above; 2.4.6 Less the amount of the actual proceeds received by Sellers in the ordinary course of business that are attributable to Hydrocarbon production from the Properties on and after the Effective Date through the Closing Date (net of any royalties and of any production, severance, sales, or other taxes actually paid by or on behalf of Sellers), together with any other monies or credits attributable to the ownership or operation of the Assets on and after the Effective Date through the Closing Date; 2.4.7 Less the amount of the Performance Deposit and all other advances and deposits relating to the Assets that are received by Sellers prior to the Closing Date and attributable to periods of time on or after the Effective Date; 2.4.8 Less an amount equal to the aggregate of all Title Indemnity Payments made in accordance with Article 3; 2.4.9 Less an amount equal to the aggregate of all Environmental Indemnity Payments made in accordance with Article 5; 2.4.10 Less an amount equal to the Allocated Value of (i) the Assets with respect to which preferential purchase rights have been exercised prior to the Closing Date, or (ii) Assets excluded for failure to obtain a Page 13 required consent prior to the Closing Date, each in accordance with Section 3.10; 2.4.11 Less the value of any Sellers' prorated shares of all accrued but unpaid Property Taxes relating to the Assets for the period prior to the Effective Date in accordance with Sections 15.1 and 15.2; 2.4.12 Less an amount equal to all Casualty Loss Amounts paid in accordance with Article 4; 2.4.13 Less or plus, as the case may be, an amount necessary to adjust for the net gas imbalances as determined pursuant to Section 13.1.3; and 2.4.14 Less an amount equal to the net proceeds and receivables related to the Assets which are payable to third parties and are held in suspense by any Seller on the Closing Date. 2.5 Payment of Adjusted Purchase Price. At the Closing, Purchaser shall cause to be delivered by wire transfer to Sellers, or, in the event Sellers so request, to an escrow agent determined by Sellers, an amount in immediately available U.S. funds equal to the Purchase Price, plus or minus the adjustments provided for in Section 2.4 calculated as provided in Section 12.3 (the "Preliminary Amount"). At the Closing, the Preliminary Amount shall be deposited to the accounts of Sellers in the amounts and into the accounts set forth in a notice to be given by Sellers to Purchaser concurrently with Sellers' delivery to Purchaser of the Closing Adjustment Statement pursuant to Section 12.3. The Preliminary Amount paid at the Closing shall be subject to later adjustment pursuant to Section 13.1. 2.6 Tax Purchase Price Allocations. Sellers and Purchaser recognize that reporting requirements, as imposed by Section 1060 of the Internal Revenue Code of 1986, as amended (the "IRC" or "Code"), and the regulations thereunder, may apply to the transaction contemplated by this Agreement. Except as may otherwise be required by the IRC and regulations thereunder or other Applicable Laws, Sellers and Purchaser agree (i) that for tax reporting purposes, the Purchase Price shall be allocated among the Assets as set forth in the final version of Exhibit J attached to this Agreement pursuant to Section 1.1.3, and such allocation shall be used in preparing Internal Revenue Service Form 8594 ("Form 8594") pursuant to the regulations under Section 1060 of the Code, and (ii) not to assert, in connection with any tax return, tax audit, or similar proceeding, any allocation of the Purchase Price that differs from that set forth in Exhibit J to this Agreement. In the event of any adjustment of the Purchase Price pursuant to the terms of this Agreement, Sellers and Purchaser shall adjust the allocations reflected in Exhibit J accordingly and report such adjustments in conformity with Section 1060 of the Code and the regulations thereunder. 3. TITLE MATTERS 3.1 Access to Records and Assets. Upon execution of this Agreement and until the Closing, and thereafter to the extent any Sellers, or any Affiliate thereof, retains physical possession of any of the Assets and/or Records, Sellers shall make the Records (including, without limitation, all revenue statements, lease operating statements, invoices, and regulatory reports necessary to permit Purchaser to verify the historical and current lease operating statements and joint interest billings prepared with respect to the Assets) available to Purchaser at Sellers' designated offices located at the offices of KEBO at 607 Page 14 Railroad Avenue, Portland, Texas, during normal business hours for examination and copying by Purchaser and shall grant to Purchaser access to such Properties for inspection. No Seller shall be obligated to perform any title work or provide abstracts other than those presently in such Seller's possession, nor will any existing title opinions be made current by any Seller. Sellers will use reasonable commercial efforts to furnish to Purchaser all other information with respect to the Assets that Purchaser may from time to time reasonably request, except to the extent that any Seller determines in good faith that it is prohibited by agreement with a third party from disclosing the information covered thereby. Purchaser agrees to conduct its due diligence in a professional and orderly manner and at its own cost and expense without disruption of any Seller's normal and usual operations. PURCHASER SHALL INDEMNIFY AND HOLD HARMLESS EACH SELLER, AND ITS AFFILIATES, TOGETHER WITH THEIR RESPECTIVE PARTNERS, CO-VENTURERS, SHAREHOLDERS, MEMBERS, OFFICERS, DIRECTORS, TRUSTEES, EMPLOYEES, AGENTS (INCLUDING, WITHOUT LIMITATION, RICHARDSON BARR SECURITIES, INC.), AND REPRESENTATIVES (COLLECTIVELY, THE "SELLERS' GROUP"), FROM ANY AND ALL CLAIMS, DEMANDS, DAMAGES, LOSSES, LIABILITIES, COSTS AND EXPENSES, INCLUDING COURT COSTS AND REASONABLE ATTORNEY'S FEES (COLLECTIVELY, "COSTS"), ARISING OUT OF, OR RESULTING FROM PURCHASER'S ACTS OR OMISSIONS IN CONNECTION WITH ITS ACCESS TO THE ASSETS, REGARDLESS OF WHETHER SUCH COSTS ARE ATTRIBUTABLE, IN WHOLE OR IN PART, TO THE NEGLIGENCE, SOLE OR CONCURRENT, OF THE SELLERS' GROUP. 3.2 Definitions. For purposes of this Agreement, the following expressions and terms will have the meanings set forth hereinafter: 3.2.1 "Sellers' Title" shall mean, as to each Well, that (i) Sellers (and upon Closing, Purchaser), by virtue of their ownership interests therein, are collectively entitled to receive a fractional decimal interest of not less than the "Net Revenue Interest" set forth for each Well on Exhibit B, without reduction, suspension, or termination throughout the productive life of each Well (unless otherwise shown on Exhibit B); (ii) Sellers are collectively obligated to bear (and after the Closing, Purchaser shall be obligated to bear) a fractional decimal interest of not more than the "Working Interest" set forth for each Well on Exhibit B of the costs and expenses related to the maintenance, development, drilling, equipping, testing, completion, sidetracking, reworking and operation of each such Well, without increase throughout the productive life thereof (unless otherwise shown on Exhibit B); and (iii) such Well is free and clear of liens, encumbrances, and other defects or irregularities in title, except for Permitted Encumbrances. 3.2.2 "Permitted Encumbrances" shall mean: (a) lessors' royalties, overriding royalties, payments out of production, reversionary interests, and other similar burdens affecting the aggregate Net Revenue Interest of all parties comprising Sellers if the net cumulative effect of such burdens does not operate to (i) reduce the aggregate Net Revenue Interest of Sellers in any Well to less than the Net Revenue Interest set forth for such Well in Exhibit B; or (ii) increase the aggregate Working Interest of Sellers in any such Well to greater than the Page 15 Working Interest set forth for such Well in Exhibit B (unless the aggregate Net Revenue Interest of Sellers therein is increased in the same proportion); (b) preferential rights to purchase, required third party consents to assignment, and similar agreements with respect to which, prior to the Closing, (i) waivers or consents are obtained from the appropriate parties; (ii) the appropriate time for asserting such rights has expired without an exercise of such rights; (iii) with respect to consents, such consent need not be obtained prior to assignment, or the failure to obtain such consent will not have a material adverse effect on the value of the affected Well, or may not reasonably be expected to subject Purchaser to liability in favor of any third party; (c) all rights to consent by, required notices to, filings with, or other actions by Governmental Bodies in connection with the sale or conveyance of the Assets if the same are customarily obtained subsequent to such sale or conveyance; (d) non-consent penalties applied against the interest of any Sellers arising under applicable operating agreements which are scheduled on Exhibit C and taken into account in the calculation of the interests shown on Exhibit B; (e) easements, rights-of-way, servitudes, permits, surface leases, and other rights in respect of surface operations that are not a part of, but that burden, the Assets; (f) such Title Defects as Purchaser has waived or released or is deemed to have waived pursuant to the terms of this Agreement; (g) the terms and conditions of all Existing Contracts; provided, however, that the effect of such terms and conditions is reflected in the calculation of the Working Interests and Net Revenue Interests set forth for the Wells in Exhibit B; (h) rights of reassignment, to the extent any exist as of the date of this Agreement, upon the surrender or expiration of any Lease; (i) liens for taxes not yet due or not yet delinquent or, if due or delinquent, that are being contested in good faith; (j) materialman's, mechanic's, repairman's, employee's, contractor's, operator's, and other similar liens or charges encumbering the Assets that arise in the ordinary course of business (i) if they have not been filed pursuant to Applicable Law, (ii) if filed, they have not yet become due and payable, or payment is being withheld as provided by Applicable Law, or (iii) if their validity is being contested in good faith by appropriate action; (k) all rights reserved to or vested in any Governmental Body to control or regulate any of the Assets in any manner, and all Applicable Laws; Page 16 (l) all defects and irregularities of title that would not reasonably be expected to result in claims that would materially and adversely affect the title of any Seller to, or the ownership, operation, or value of, the Assets, including, without limitation (i) defects in the early chain of title consisting of the failure to recite marital status or the omission of succession or heirship proceedings; (ii) defects or irregularities arising out of the lack of a survey (but not defects or irregularities, the existence of which is demonstrated by a survey); (iii) defects or irregularities arising out of or relating to the lack of powers of attorney from corporations to execute and deliver documents on their behalf or lack of spousal joinder; (iv) defects of title which result from the failure to file assignments or other documents in the state or federal records so long as such assignments or other documents are properly recorded in the county records; and (v) irregularities cured by possession under applicable statutes of limitation and statutes relating to acquisitive (or liberative) prescription; and (m) all other liens, charges, encumbrances, instruments, obligations, defects and irregularities affecting the Assets which, individually or in the aggregate, do not: (i) interfere materially with the operation, value, or use of any of the Wells; (ii) do not prevent Purchaser from receiving the proceeds of production from any of the Wells; (iii) do not reduce the aggregate interests of all Sellers with respect to Hydrocarbons produced from any Well below the Net Revenue Interest set forth for such Well on Exhibit B; or (iv) do not increase the aggregate share of the costs and expenses that Sellers are obligated to pay above the Working Interest set forth for such Well in Exhibit B without a proportionate increase in the Net Revenue Interest for such Well. 3.2.3 "Title Defect" shall mean any matter: (i) that would cause the title to any Well fail to be as reflected in Sellers' Title, or that reflects a failure in Sellers' title to any Property; (ii) has a Defect Value (as hereinafter defined) which is greater than $25,000; and (iii) as to which notice is provided to Sellers in a timely manner as provided for in Section 3.3. 3.2.4 "Allocated Value" means, with respect to each Well, the amount set forth on the final version of Exhibit B attached to this Agreement pursuant to Section 1.1.3 under the column styled "Allocated Value" for such Well. For purposes of this Agreement, Sellers and Purchaser agree and stipulate that the Allocated Values set forth in Exhibit B have been established solely for use in calculating adjustments to the Purchase Price as provided herein, and not for purposes of federal, state, local, or foreign income taxation, such Allocated Values being solely for the convenience of the Parties. 3.3 Notice of Title Defect. During the period of time between the execution of this Agreement and September 21, 2007 (the "Due Diligence Period"), Purchaser may review title to the Assets and may notify Sellers in writing (the "Title Defect Notice") of any Title Defect; provided, however, Purchaser shall notify Sellers of any Title Defect it discovers as soon as reasonably practicable after its discovery. Any notice provided hereunder shall include appropriate evidence to substantiate Purchaser's position, including a description of the Title Defect, the basis for the Title Defect, the portion of the Well or Wells affected by the Title Defect, the Allocated Value therefore, the amount by which Purchaser reasonably believes, in accordance with the provisions of Section 3.6, Page 17 the value of the affected Well or Wells would be reduced if the Title Defect were uncured (the "Defect Value"), and the computations and information upon which Purchaser's belief is based. Purchaser will be deemed to have conclusively waived any matter reflected in the public records of the county where the Properties are located as of the end of the Due Diligence Period or in any documents or records made available by Sellers to Purchaser pursuant hereto that would otherwise qualify as a Title Defect but about which Purchaser fails to notify Sellers in writing in the manner described above prior to the expiration of the Due Diligence Period. 3.4 Remedies for Title Defects. For any Title Defect properly asserted by Purchaser during the Due Diligence Period, subject to the termination rights of both Parties pursuant to Section 3.8 hereof, Sellers shall have the option, in their sole discretion, of (i) curing the Title Defect, (ii) contesting the Title Defect or the Defect Value, or (iii) subject to the terms of Section 3.5.2, reducing the Purchase Price by the amount of the Defect Value ("Title Indemnity Payment"). 3.5 Procedure for Resolving Title Defects. With respect to Title Defects properly and timely asserted by Purchaser as provided herein, the following procedures shall apply. 3.5.1 If Sellers contest the existence of a Title Defect or the Defect Value applicable thereto, Sellers shall so notify Purchaser in writing on or before five (5) days after Sellers' receipt of the Title Defect Notice ("Rejection Notice"). The Rejection Notice shall state with reasonable specificity the basis of Sellers' rejection of the Title Defect or the Defect Value. No later than five (5) days following Purchaser's receipt of the Rejection Notice, representatives of Purchaser and Sellers, knowledgeable in title matters, shall meet and either: (i) agree to mutually reject the particular Title Defect, or (ii) agree on the validity of such Title Defect and the Defect Value, in which case Sellers shall cure such Title Defect at their own expense and to their reasonable satisfaction and, failing such cure, make the Title Indemnity Payment therefor, subject to the limitations set forth in Section 3.5.2. If the Parties cannot agree on either option (i) or (ii) in the preceding sentence, the Title Defect or the Defect Value subject to the Rejection Notice shall be submitted to dispute resolution in accordance with the procedures set forth in Section 3.9. Each Title Defect as to which Sellers and Purchaser reach agreement hereunder concerning the validity of such Title Defect and its Defect Value or as to which such validity and/or Defect Value is finally determined pursuant to Section 3.9 shall be referred to herein as a "Finally Determined Title Defect." 3.5.2 Notwithstanding the provisions of Section 3.5.1, and except as otherwise provided in Section 3.10, Sellers shall not be obligated to pay any Title Indemnity Payment, Environmental Indemnity Payment, or Casualty Loss Amount hereunder unless, and only to the extent that, the sum of (i) the aggregate Defect Values for all uncured, Finally Determined Title Defects, plus (ii) the aggregate Remediation Amounts for all unremedied Finally Determined Environmental Defects, plus (iii) the aggregate Casualty Loss Amounts for all unrepaired Finally Determined Casualty Losses, exceeds a deductible of five percent (5.0%) of the Purchase Price (the "Deductible"). If Purchaser asserts Finally Determined Title Defects for which Sellers elect to make a Title Indemnity Payment, and the sum of (x) the aggregate Defect Values for such uncured Finally Determined Title Defects plus (y) the aggregate Remediation Amounts for all unremedied Finally Determined Environmental Page 18 Defects, plus (z) the aggregate Casualty Loss Amounts for all unrepaired Finally Determined Casualty Losses do not exceed the Deductible, no Title Indemnity Payment shall be made. 3.6 Value of Defects. The Defect Value for a Title Defect shall be determined as follows: 3.6.1 If, because of the Title Defect, title to a particular Well fails completely with the effect that Sellers have no ownership interest in the relevant Well, the Defect Value shall be the Allocated Value of that Well. 3.6.2 If the Title Defect consists of a lien, encumbrance or other charge upon a Well which is liquidated in amount, the Defect Value shall be the amount necessary to pay the obligee to remove such Title Defect. 3.6.3 If the actual aggregate Net Revenue Interest of Sellers in a Well is less than the Net Revenue Interest set forth for such Well in Exhibit B throughout the remaining productive life of such Well, the Defect Value shall be an amount equal to (i) the ratio of (x) the difference obtained by subtracting the actual Net Revenue Interest for such Well from the Net Revenue Interest set forth for such Well on Exhibit B, to (y) the Net Revenue Interest set forth for such Well on Exhibit B, (ii) multiplied by the Allocated Value for such Well. 3.6.4 If the actual aggregate Net Revenue Interest of Sellers in a Well is less than the Net Revenue Interest set forth for such Well in Exhibit B for less than the remaining productive life of such Well, or if the actual aggregate Working Interest of Sellers in a Well is greater than the Working Interest set forth for such Well in Exhibit B without a proportionate increase in the relevant Net Revenue Interest, then the Defect Value shall be equal to the Allocated Value for such Well multiplied by a fraction (i) the numerator of which shall be the net present value, as of the Effective Date, of the aggregate interests of Sellers in the future net revenues from such Well set forth in that certain reserve report dated May 31, 2007, covering the Properties as of June 1, 2007, prepared by R. A. Lenser & Associates (the "Lenser Reserve Report"), a copy of which has been previously delivered to Purchaser, discounted at ten percent (10%) per annum (the "PV-NRI"), minus the net present value, as of the Effective Date, of the aggregate interests of Sellers in the future net revenues from such Well calculated based upon the same production, cost, and assumed future price estimates and such other methods, techniques and assumptions used in the preparation of the Lenser Reserve Report but taking into account the Title Defect, and (ii) the denominator of which shall be the PV-NRI. 3.6.5 If the Title Defect is one other than described in Sections 3.6.1 through 3.6.4, the Defect Value shall be the amount agreed to by Sellers and Purchaser or, failing such agreement, the Defect Value shall be determined pursuant to Section 3.9 below. 3.7 Interest Additions. If Sellers discover that the actual aggregate Net Revenue Interest of Sellers for a Well is greater than the Net Revenue Interest shown for such Well on Exhibit B, and such Well is otherwise free of Title Defects (an "Interest Addition"), then Sellers shall, from time to time, have the right to give Purchaser written notice of such Interest Additions ("Interest Page 19 Addition Notice"), as soon as practicable but no later than the end of the Due Diligence Period, stating with reasonable specificity the Well affected, the particular Interest Addition claimed, and Sellers' good faith estimate of the amount by which the Additional Interest increases the value of the affected Well over and above the Allocated Value for such Well ("Interest Addition Value"). If Purchaser agrees with the existence of the Interest Addition and Sellers' good faith estimate of the Interest Addition Value, and such Interest Addition Value exceeds $25,000, then the Interest Addition Value shall be applied as an offset to any Title Indemnity Payment or Environmental Indemnity Payment required of Sellers ("Offset"). If Purchaser contests the existence of the Interest Addition or Sellers' good faith estimate of the Interest Addition Value, then Purchaser shall so notify Sellers in writing on or before five (5) days after receipt of the Interest Addition Notice ("Interest Addition Rejection Notice"). The Interest Addition Rejection Notice shall state with reasonable specificity the basis of Purchaser's rejection of the Additional Interest or the Interest Addition Value. No later than five (5) days following delivery of the Interest Addition Rejection Notice, representatives of Purchaser and Sellers, knowledgeable in title matters, shall meet and either (i) agree to mutually reject the Interest Addition, in which case Sellers shall waive the Interest Addition, or (ii) agree on the validity of such Interest Addition and the Interest Addition Value, in which case Sellers shall be entitled to an Offset. If the Parties cannot agree on either option (i) or (ii) in the preceding sentence, the Interest Addition subject to the Interest Addition Rejection Notice shall be submitted to dispute resolution in accordance with the procedures set forth in Section 3.9. If Purchaser fails to timely deliver an Interest Addition Rejection Notice, Purchaser shall be deemed to have accepted the validity of the Interest Addition and the Interest Addition Value, and Sellers shall be entitled to an Offset as described above. 3.8 Right to Terminate Agreement. Notwithstanding anything in Article 3, Article 4 or Article 5, if the sum of (i) the Defect Values for all Finally Determined Title Defects (which, for purposes of this Section 3.8, shall include preferential rights to purchase and required third person consents to assignment that result in the exclusion of one or more Assets from the Closing pursuant to Section 3.10, but shall exclude liens, encumbrances, or other charges upon a Well as to which Sellers obtain releases upon Sellers' payment or discharge of the indebtedness or other obligations secured thereby), plus (ii) the Remediation Amounts for all Finally Determined Environmental Defects, plus (iii) the Casualty Loss Amounts for all Finally Determined Casualty Losses that occur prior to the Closing Date, equals or exceeds, independently of and without regard to the Deductible, fifteen percent (15%) of the Full Interest Purchase Price (the "Termination Threshold"), and Sellers elect not, or are unable, to cure, remedy, or repair such Finally Determined Title Defects, Finally Determined Environmental Defects, or Finally Determined Casualty Losses, either Party may elect to terminate this Agreement without liability to the other Party, in which case Purchaser shall be entitled to a refund of the Performance Deposit. 3.9 Expert Determination. 3.9.1 If Sellers and Purchaser are unable to agree, as herein provided, regarding the existence of a Title Defect, Environmental Defect, or Casualty Loss, the applicable Defect Value, Remediation Amount (as hereinafter defined), or reduction in value resulting from a Casualty Loss, or any other matter to be resolved under this Article 3, Article 4, or Article 5, the Parties shall promptly refer the matter for determination in the manner hereinafter provided to a person selected by Page 20 mutual agreement of the Parties who possesses the requisite knowledge, skill and experience to determine the issue in question (the "Defect Expert"). The Defect Expert may enlist the advice of attorneys, accountants, geologists, landmen, or any petroleum engineer or environmental consultant mutually agreed upon by the Parties and any other neutral expert as reasonably necessary. 3.9.2 Upon referral to the Defect Expert, the Parties shall each deliver to the other and the Defect Expert a notice setting forth in adequate detail the issues to be determined by the Defect Expert and the decision (on a word-for-word basis) that such Party wishes the Defect Expert to make with respect to the issues to be determined (the "Decision Notice"); provided, however, in preparing their Decision Notice, each Party (as well as the Defect Expert) shall be bound by the terms of this Agreement. Within two (2) business days after the giving of the two Decision Notices, the Parties shall attend a meeting with the Defect Expert at a mutually acceptable time and place to discuss fully the content of such Decision Notice and, based thereon, determine whether either or both wish to modify their Decision Notices in any way. Any such modifications shall be discussed, so that when each Party finalizes its Decision Notice, it shall do so with full knowledge of the content of the other Party's final Decision Notice. The finalization of such Decision Notices and the delivery of same by each Party to the other shall occur at the meeting unless the Parties agree to have one or more additional meetings for such purposes. The Defect Expert shall be required to adopt the decision set forth in either final Decision Notice and shall have no power whatsoever to reach any other result. Such Defect Expert shall adopt the decision that, in his or her judgment, is the more fair and equitable and in conformity with this Agreement and industry standards. 3.9.3 The decision, made in writing and signed by the Defect Expert, shall determine such dispute. Such decision shall be made, signed and delivered to the Parties at the meeting unless otherwise agreed by the Parties. The expenses of the Defect Expert and any other expert retained by the Defect Expert under this Agreement shall be borne by the Party whose final Decision Notice was not chosen by the Defect Expert, except that each Party shall bear the compensation and expense of its own counsel, witnesses and employees. The determination and award of the Defect Expert shall be final and binding upon the Parties, and judgment may be entered thereon in any court of competent jurisdiction upon the application of either Party. 3.10 Preferential Purchase Rights and Consents to Assign. 3.10.1 Within five (5) days after the execution of this Agreement, Sellers shall send to the holder of each preferential right to purchase identified on Exhibit D a written notice offering to sell to such holder, in accordance with the contractual provisions applicable to such right, the Asset covered by such right on substantially the same terms as this Agreement and for the Allocated Value applicable to such Asset as set forth in Exhibit B, subject to adjustments in price in the same manner that the Purchase Price is adjusted pursuant to Section 2.4 of this Agreement. Similarly, within five (5) days after the execution of this Agreement, Sellers shall send to each party identified on Exhibit D from whom a consent to assignment is required prior to the Closing a written notice requesting such party to consent to the assignment of the affected Asset to Purchaser. Both Purchaser and Sellers shall use Page 21 reasonable efforts to identify additional preferential rights to purchase and consents to assign and, if any such rights are identified, Sellers shall notify such holder(s) in accordance with the terms of this Section 3.10.1 within five (5) days of the identification of such additional rights. 3.10.2 If an Asset (including, without limitation, an Existing Contract) is subject to a preferential right to purchase, right of first refusal, right of first offer, or similar right that is exercised prior to the Closing, then at Purchaser's option, (i) Sellers shall convey the affected Asset to Purchaser at the Closing subject to such outstanding preferential right to purchase or similar right, or (ii) the affected Asset shall be excluded from the Assets conveyed to Purchaser at the Closing, the Purchase Price shall be reduced by an amount equal to the full Allocated Value of the affected Asset without regard to the existence or status of amounts credited against the Deductible, and Sellers shall be entitled to retain all proceeds paid for the affected Asset by the person exercising such preferential right to purchase or similar right. No reduction of the Purchase Price pursuant to this Section 3.10.2 shall be taken into account in determining whether the Deductible has been met. If Purchaser purchases at the Closing an Asset burdened by a preferential right to purchase or similar right that has not been exercised as of the Closing Date, regardless of whether the time period for the exercise of such right has expired, no reduction of the Adjusted Purchase Price paid at the Closing shall be made with respect thereto. If, for any reason, such preferential right to purchase or similar right is successfully exercised by the holder thereof after the Closing, Purchaser shall be entitled to retain all proceeds paid for the affected Asset by the holder of the relevant preferential right to purchase or similar right. If the holder of such a preferential right to purchase or similar right notifies Sellers that it intends to consummate the purchase of an Asset to which its preferential purchase right applies, but the holder of such preferential right fails to consummate the purchase of the relevant Asset such that the holder's right expires or is terminated, whether before or after Closing, then Sellers, as promptly as possible thereafter, but in no event later than one hundred fifty (150) days after the Closing, shall so notify Purchaser. Within fifteen (15) days after Purchaser's receipt of such notice from Sellers, Sellers shall sell to Purchaser, and Purchaser shall purchase from Sellers, for a price equal to the Allocated Value of such Asset and subject to and in accordance with the other terms of this Agreement, the Asset to which such preferential right to purchase or similar right applies. 3.10.3 If an Asset (including, without limitation, an Existing Contract) is subject to a third person consent to assignment required to be obtained before the relevant Asset may be assigned, but the third party holding such right to consent neglects or refuses to give such consent prior to the Closing, Sellers will promptly so notify Purchaser and, at Purchaser's option, (i) Sellers shall convey the affected Asset to Purchaser at the Closing subject to such outstanding consent, in which case the Allocated Value applicable to the affected Asset shall be included in the Purchase Price paid by Purchaser at the Closing, or (ii) the affected Asset shall be excluded from the Assets conveyed at Closing, title thereto shall be retained by Sellers subject to the terms of this Section 3.10.3, and the Purchase Price shall be reduced by an amount equal to the full Allocated Value of the affected Asset without regard to the existence or status of amounts credited against the Deductible. After the Closing, Sellers shall continue to use their reasonable commercial efforts (which shall in no event include any obligation to pay money to the owners of such rights or undertake any Page 22 legal obligation) to obtain all consents to assignment as promptly after the Closing as is possible. If Sellers obtain the relevant outstanding consent to assignment, and Purchaser has elected to exclude the affected Asset from the Assets conveyed at Closing, then within fifteen (15) days after Sellers' receipt of such consent, Sellers shall convey to Purchaser, and Purchaser shall purchase from Sellers, for a price equal to the Allocated Value of such Asset and subject to and in accordance with the other terms of this Agreement, the Asset to which such consent requirement applies. If such outstanding consent is not obtained prior to the expiration of one hundred fifty (150) days after the Closing Date, and Purchaser has elected to purchase and receive a conveyance of the affected Asset at the Closing, Purchaser shall have the right and option to reassign the affected Asset to Sellers, without representation or warranty as to title except as against those claiming the same by, through, or under Purchaser and subject only to those matters to which the Asset was subject at Closing, and Sellers shall refund to Purchaser the Allocated Value for such Asset subject to adjustment for revenues, expenses, and other matters attributable to such Asset since the Effective Date in accordance with Section 2.4. Upon such reassignment, Sellers shall have no further liability to Purchaser with respect to such Asset under this Section 3.10.3. 4. CASUALTY LOSS. 4.1 Casualty Loss. If, prior to the Closing, any of the Assets are substantially damaged or destroyed by fire, explosion, accident, act of the public enemy, act of God, or other similar event or occurrence ("Casualty Loss"), Sellers shall notify Purchaser promptly after Sellers learn of such event. Sellers shall have the right, but not the obligation, to cure any such Casualty Loss by repairing such damage or, in the case of Personal Property or fixtures, replacing the damaged Asset with equivalent items no later than the Closing Date. If any Casualty Loss exists at the Closing, Purchaser shall proceed to purchase the damaged Assets, and the Purchase Price shall be reduced by the aggregate reduction in value of all Assets affected by such Casualty Loss ("Casualty Loss Amount"), as determined by the mutual agreement of the Parties; provided that if the Parties are unable to agree on such amount prior to the Closing, then such determination shall be made by the Defect Expert as provided in Section 3.9 above. Each Casualty Loss as to which Sellers and Purchaser reach agreement on the Casualty Loss Amount prior to the Closing or as to which such Casualty Loss Amount is finally determined pursuant to Section 3.9 shall be referred to herein as a "Finally Determined Casualty Loss." Notwithstanding anything to the contrary contained in this Section 4.1, (i) a reduction of the Purchase Price attributable to any Casualty Loss shall be made only to the extent permitted under the provisions of Section 3.5.2, and (ii) if a Casualty Loss does not result in a reduction of the Purchase Price hereunder, Sellers shall promptly remit to Purchaser all insurance proceeds and shall take all actions necessary to permit Purchaser to pursue any claims against third parties, in each case relating to any such Casualty Loss that is not repaired by Sellers; provided, however, that if any reduction to the Purchase Price occurs as the result of a Casualty Loss, Sellers shall be entitled to retain all insurance proceeds and claims against other parties relating to any such Casualty Loss. For purposes of this Section 4.1, normal wear and tear shall not be considered a Casualty Loss. Page 23 5. ENVIRONMENTAL CONDITION 5.1 Physical Condition of the Assets. The Assets have been used for Hydrocarbon drilling and production operations and various related oil field operations. Physical changes in or under the Assets or adjacent lands may have occurred as a result of such uses. The Assets also may contain buried pipelines and other equipment, whether or not of a similar nature, the locations of which may not now be known by Sellers or be readily apparent by a physical inspection of the Assets. Purchaser understands that Sellers do not have the requisite information with which to determine the exact nature or condition of the Assets or the effect any such use has had on the physical condition of the Assets. In addition, Purchaser acknowledges that some oil field production equipment may contain asbestos and/or naturally occurring radioactive material ("NORM"). In this regard, Purchaser expressly understands that NORM may affix or attach itself to the inside of wells, materials, and equipment as scale or in other forms, and that the wells, materials, and equipment located on the Assets may contain NORM and that NORM containing materials may be buried or have been otherwise disposed of on the Assets. Purchaser also expressly understands that special procedures may be required for the removal and disposal of asbestos and NORM from the Assets where it may be found. 5.2 Environmental Assessment. 5.2.1 Prior to the Closing, and upon reasonable, prior notice to Sellers, Purchaser and any third party environmental consulting firm approved by DSX on behalf of Sellers (which consent shall not be unreasonable withheld) and retained by Purchaser (the "Purchaser's Environmental Consultant"), to the same extent Sellers have such right, shall have the right to enter upon the Assets and all buildings and improvements thereon, inspect the same, conduct soil and water tests and borings, and generally conduct such tests, examinations, investigations, and studies as may be necessary or appropriate for the preparation of appropriate engineering and other reports, judgments, and environmental assessments in relation to the Assets, their environmental condition, and the existence of Environmental Defects (as hereinafter defined) (such inspection and investigation being called herein "Purchaser's Environmental Assessment"). Purchaser shall promptly provide to Sellers a copy of Purchaser's Environmental Assessment, including any reports, data, and conclusions. Purchaser and Sellers shall keep strictly confidential any data or information acquired from such examinations and the results of all analyses of such data and information and shall not disclose same to any person or Governmental Body without the prior written approval of the other Party, except such disclosure as may be required by Applicable Law. This obligation of confidentiality shall survive the Closing. 5.2.2 WITH RESPECT TO PURCHASER'S ENVIRONMENTAL ASSESSMENT, PURCHASER SHALL INDEMNIFY AND HOLD HARMLESS THE SELLERS' GROUP FROM ANY AND ALL COSTS ARISING OUT OF OR RESULTING FROM THE ACTS OR OMISSIONS OF PURCHASER OR PURCHASER'S ENVIRONMENTAL CONSULTANT IN CONNECTION WITH PURCHASER'S ENVIRONMENTAL ASSESSMENT, INCLUDING, WITHOUT LIMITATION, COSTS RELATING TO (I) ANY AND ALL STATUTORY OR COMMON-LAW LIENS OR OTHER ENCUMBRANCES FOR LABOR OR MATERIALS FURNISHED IN CONNECTION WITH SUCH TESTS, Page 24 SAMPLINGS, STUDIES, OR SURVEYS AS PURCHASER OR PURCHASER'S ENVIRONMENTAL CONSULTANT MAY CONDUCT WITH RESPECT TO THE ASSETS AND (II) CLAIMS ASSERTED BY PURCHASER, ITS AFFILIATES, AND THEIR RESPECTIVE PARTNERS, SHAREHOLDERS, MEMBERS, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS AND REPRESENTATIVES (COLLECTIVELY, THE "PURCHASER GROUP") FOR INJURY TO OR DEATH OF ANY PERSON, PERSONS, OR OTHER LIVING THINGS, OR DAMAGE TO OR LOSS OF PROPERTY, IN EITHER CASE RESULTING FROM, ARISING OUT OF, OR OCCURRING IN CONNECTION WITH PURCHASER'S ENVIRONMENTAL ASSESSMENT, REGARDLESS OF WHETHER SUCH COSTS ARE ATTRIBUTABLE, IN WHOLE OR IN PART, TO THE NEGLIGENCE, SOLE OR CONCURRENT, OF THE SELLERS' GROUP. 5.3 Environmental Defect Notice. If Purchaser reasonably determines, as a result of Purchaser's Environmental Assessment, that there exists or may exist an Environmental Defect, Purchaser may notify Sellers thereof in writing as soon as reasonably practical after its discovery, but in any event before the end of the Due Diligence Period (the "Environmental Defect Notice"). Any notice provided hereunder shall include appropriate evidence to substantiate Purchaser's position, including a description of the Environmental Defect, the Environmental Law applicable to the Environmental Defect, Purchaser's basis for believing that Sellers is in violation of such Environmental Law, the Well or Wells affected by the Environmental Defect, an estimate from Purchaser's Environmental Consultant outlining the cost for Remediation (as hereinafter defined), which estimate shall identify the methods and scope of the remediation proposed and all assumptions relied upon by Purchaser's Environmental Consultant in calculating the estimated cost of Remediation, and a calculation by Purchaser of the Remediation Amount (as hereinafter defined) attributable to the Environmental Defect based upon the estimate of Purchaser's Environmental Consultant. Purchaser will be deemed to have conclusively waived any Environmental Defect discovered by Purchaser during the Due Diligence Period about which it fails to notify Sellers in writing prior to the expiration of the Due Diligence Period. 5.4 Remedies for Environmental Defects. For any Environmental Defect properly asserted by Purchaser during the Due Diligence Period, subject to the termination rights of both Parties pursuant to Section 3.8, Sellers shall have the option, in their sole discretion, of (i) remedying the Environmental Defect, (ii) contesting the Environmental Defect or the Remediation Amount, or (iii) subject to the terms of Section 5.5.2, reducing the Purchase Price by an amount equal to the Remediation Amount ("Environmental Indemnity Payment"). 5.5 Procedure for Resolving Environmental Defects. With respect to Environmental Defects properly and timely asserted by Purchaser as provided herein, the following procedures shall apply. 5.5.1 If Sellers contest the existence of an Environmental Defect or the Remediation Amount, Sellers shall provide Purchaser a Rejection Notice with respect thereto on or before five (5) days after Sellers' receipt of the Environmental Defect Notice. The Rejection Notice shall state Page 25 with reasonable specificity the basis of Sellers' rejection of the Environmental Defect or the Remediation Amount. No later than five (5) days following Purchaser's receipt of the Rejection Notice, representatives of Purchaser and Sellers, knowledgeable in environmental matters, shall meet and either: (i) agree to mutually reject the particular Environmental Defect, or (ii) agree on the validity of such Environmental Defect and the Remediation Amount, in which case Sellers shall remedy such Environmental Defect at their own expense and to the satisfaction of the appropriate Governmental Body prior to the Closing or as soon thereafter as is reasonably practicable and, failing such remedy, make the Environmental Indemnity Payment therefor, subject to the limitation set forth in Section 5.5.2. If the Parties cannot agree on either option (i) or (ii) in the preceding sentence, the Environmental Defect or the Remediation Amount subject to the Rejection Notice shall be submitted to dispute resolution in accordance with the procedures set forth in Section 3.9. Each Environmental Defect as to which Sellers and Purchaser reach agreement hereunder concerning the validity of such Environmental Defect and its Remediation Amount or as to which such validity and/or Remediation Amount is finally determined pursuant to Section 3.9 shall be referred to herein as a "Finally Determined Environmental Defect." 5.5.2 Notwithstanding the provisions of Section 5.5.1, Sellers shall be obligated to make an Environmental Indemnity Payment only if, and then only to the extent, provided in Section 3.5.2. If Purchaser asserts Finally Determined Environmental Defects for which Sellers elect to make an Environmental Indemnity Payment, and the sum of the aggregate Remediation Amounts for such unremedied Finally Determined Environmental Defects plus (ii) the aggregate Defect Values for all uncured Finally Determined Title Defects, plus (iii) the aggregate Casualty Loss Amounts for all unrepaired Finally Determined Casualty Losses do not exceed the Deductible, no Environmental Indemnity Payment shall be made. 5.6 Definitions. For purposes of this Agreement, the following expressions and terms will have the meanings set forth hereinafter: 5.6.1 "Applicable Laws" shall mean all laws, statutes, treaties, rules, codes, ordinances, regulations, certificates, orders, interpretations, licenses and permits of any Governmental Body, including the common or civil law, (including, without limitation, those pertaining to occupational health and safety, consumer product safety, employee benefits, the environment, securities or zoning) and all judgments, decrees, injunctions, writs, orders, or like action of any court, arbitrator, or other Governmental Body of competent jurisdiction. 5.6.2 "Environmental Defect" shall mean a condition that exists prior to the Effective Date, and only to the extent in existence as of the Effective Date, with respect to the air, land, soil, surface, subsurface strata, surface water, ground water or sediments which causes an Asset to be subject to definitive remediation within a time certain under Environmental Laws in effect as of the Effective Date, but only to the extent that (i) the condition was not otherwise known to Purchaser prior to the execution of this Agreement, and (ii) the Remediation Amount, net to Purchaser's interest, will exceed the sum of $50,000.

PURCHASER WAIVES ITS RIGHTS, IF ANY, UNDER THE DECEPTIVE TRADE PRACTICES-CONSUMER PROTECTION ACT, SECTION 17.41, ET SEQ., TEXAS BUSINESS AND COMMERCE CODE, A LAW THAT GIVES CONSUMERS SPECIAL RIGHTS AND PROTECTIONS. AFTER CONSULTATION WITH AN ATTORNEY OF ITS OWN SELECTION, PURCHASER VOLUNTARILY CONSENTS TO THIS WAIVER. 6.2 Representations. Each Seller, on its own behalf and not on behalf of any other Seller, and severally according to its ownership interests in the Assets and not jointly or collectively, represents and warrants to Purchaser, as of the date hereof and as of the Closing Date, as follows: 6.2.1 Existence. Except for those Sellers that are individuals, each Seller is a legal entity of the type identified for such Seller on the final version of Schedule 6.2.1 attached hereto pursuant to Section 1.1.3 that Page 28 is (i) duly organized or duly formed, as applicable, under the laws of the state also identified for such Seller on Schedule 6.2.1; (ii) validly existing; (iii) if required to pay state franchise or similar taxes under Applicable Laws, in good standing under the laws of its state of its organization or formation; and (iv) if organized or formed under the laws of a state other than Texas, duly qualified to do business in and, if required to pay state franchise or other taxes under Texas law, in good standing under the laws of, the State of Texas. 6.2.2 Power. Each Seller has full capacity, power, and authority to carry on its business as presently conducted, to enter into this Agreement and any other documents and agreements contemplated hereby, and to perform its obligations under this Agreement. 6.2.3 Authorization. The execution, delivery, and performance by each Seller of this Agreement and the consummation of the transactions contemplated hereby have been duly and validly authorized and approved by all necessary corporate, partnership, limited liability company, trust, or other action of each Seller and will not violate or be in conflict with, or result in a breach, or trigger a default (or an event that, with the lapse of time or the giving of notice, or both, would constitute a default) under the provisions of, (i) any material note, bond, mortgage, indenture, Lease contract (including the Existing Contracts), agreement, or instrument to which any Seller is a party, or by which any Seller is bound, or to which any Asset is subject, (ii) the organizational and governing documents of any Seller, or (iii) any judgment, decree, order, law, statute, rule, or regulation applicable to any Seller or any Asset, the non-compliance with which would have a material adverse effect on Purchaser, its ownership or operation, after the Closing, of any of the Assets, or the ability of any Seller to consummate the transactions contemplated herein. This Agreement has been, and the other documents provided for herein to be executed and delivered by Sellers to Purchaser at the Closing will be, duly executed and delivered on behalf of each Seller and constitute or shall constitute the legal, valid, and binding obligations of each Seller, enforceable in accordance with their respective terms, subject to the effects of bankruptcy, insolvency, reorganization, moratorium, and similar laws, as well as principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). 6.2.4 Brokers. No Seller has incurred any obligation or liability, contingent or otherwise, for brokers' or finders' fees relating to the matters provided for in this Agreement which will be the responsibility of Purchaser. Any such obligation or liability of any Seller shall be the sole obligation of such Seller. 6.2.5 Certain Tax Matters. Each Seller has filed all tax returns that it was required to file and has paid all taxes shown thereon as owing or subsequently assessed with respect thereto. The agreements to which the Properties are subject do not create, for federal income tax purposes, a partnership among any of the parties to such agreements for which a partnership income tax return is required to be filed under Subchapter K of Chapter 1 of Subtitle A of the IRC (other than a partnership for which an election is in effect pursuant to the provisions of Section 761 of the IRC and the regulations thereunder to be excluded from such provisions). Page 29 6.2.6 Pending Claims and Litigation. There are no suits, actions or other legal, administrative, or arbitration proceedings that are pending or, to each Seller's knowledge, threatened in writing against any Seller, KEBO, or any of the Assets that would, if determined adversely to Sellers, (i) result in the material impairment or loss of Sellers' title to the relevant Assets, (ii) materially hinder or impede the operation of all or any material portion of such Assets, or (iii) that would, if determined adversely to the Parties, restrain, prohibit, or impose damages on Purchaser or Sellers with respect to, or otherwise materially impair Sellers' ability to consummate, the transactions contemplated by this Agreement. 6.2.7 Preferential Rights; Required Consents. Except as otherwise reflected in Exhibit D, none of the Leases or Existing Contracts is subject to a preferential right to purchase, third party consent to assignment requirement, right of first refusal, or right of first offer. 6.2.8 Governmental Approvals. Except for approvals by Governmental Bodies customarily obtained after the Closing, no authorization, consent, approval, exemption, franchise, permit, or license of, or filing with, any Governmental Body is required to authorize, or is otherwise required by any Governmental Body in connection with, the valid execution and delivery by Sellers of this Agreement, the transfer of the Assets by Sellers to Purchaser, or the performance by Sellers of their other obligations hereunder. 6.2.9 Leases. To each Seller's knowledge, each Lease is in full force and effect. Each Seller has, in all material respects, fulfilled all requirements for filings, certificates, consents, approvals, disclosures, and similar matters contained in the Leases and Applicable Law, and each Seller is fully qualified to own, operate, and transfer the Leases under the terms thereof and Applicable Law. No Seller is in material breach or material default, and there has occurred no event, fact, or circumstance that, with the lapse of time or the giving of notice, or both, would constitute such a material breach or material default by any Seller, with respect to any terms of any Lease. No lessor under any Lease has given or, to any Seller's knowledge, threatened to give notice of any action to terminate, cancel, rescind, repudiate, or procure a judicial reformation of any Lease or any provision thereof. 6.2.10 Payments Under the Leases. To each Seller's knowledge, such Seller has correctly made, or caused to be correctly made, all payments, including, without limitation, royalties, rentals, shut-in well payments, and other lease maintenance payments, due in respect of the Leases thereunder and required to be made by such Seller. 6.2.11 Gas Imbalances. Except for those listed on Exhibit G, there exist no production imbalances or imbalances with respect to any pipeline, storage, or processing facility or other conditions regarding Hydrocarbons taken or marketed from the Assets or any portion thereof which could result in: (a) a portion of the interest of Sellers in such Hydrocarbon production being taken or delivered after the Closing without Purchaser then receiving payment therefor or at the price it would have received absent such imbalance; or Page 30 (b) Sellers being obligated to make payment to any person or entity as a result of such imbalance; or (c) Sellers being obligated, by virtue or any prepayment arrangement, take-or-pay agreement, or similar arrangement, to deliver Hydrocarbons produced from the Assets at some future time without then receiving full payment therefor. Notwithstanding anything else to the contrary contained herein, Purchaser's sole and exclusive remedy with respect to any breach of the representation and warranty contained in this Section 6.2.11 shall be an adjustment to the Purchase Price at the Closing. 6.2.12 Existing Contracts. Except for those contracts for the sale of Hydrocarbons which are terminable within thirty-one (31) days or less, to Sellers' knowledge, Exhibit C contains a complete list of all contracts and agreements that constitute the Existing Contracts. With respect to the Existing Contracts: (i) to each Seller's knowledge, all Existing Contracts are in full force and effect; (ii) no Seller is in material breach or material default, and there has occurred no event, fact, or circumstance that, with the lapse of time or the giving of notice, or both, would constitute such a material breach or material default by any Seller, with respect to the terms of any Existing Contract; (iii) to each Seller's knowledge, no party to an Existing Contract is in material breach or material default with respect to the terms of any Existing Contract; and (iv) no Seller or, to each Seller's knowledge, any other party to an Existing Contract has given or threatened to give notice of any action to terminate, cancel, rescind, or procure a judicial reformation of such Existing Contract or any provision thereof. 6.2.13 Compliance With Applicable Laws.

Each Seller has all governmental permits required in connection with the ownership and operation of the Assets; has properly made all filings necessary or appropriate to obtain such governmental permits; and all of such governmental permits and filings are in full force and effect. No Seller has received notice from any Governmental Body or other person that any such Applicable Law, governmental permit, or filing has been violated or not complied with in any material respect with respect to the Assets by Sellers. 6.2.14 Wells. As of the date of this Agreement, the Wells described on Exhibit B are the only wells currently capable of producing Hydrocarbons located on the Properties. All of such Wells have been, or will be, drilled, completed, and operated within the boundaries of the relevant Leases or within the limits otherwise permitted by contract and by Applicable Law and in compliance with the provisions of the applicable Leases, Existing Contracts, and all Applicable Laws. The production of Hydrocarbons from such Wells has not been in excess of the allowable production established for each Well. All Hydrocarbon wells located on the Leases that have permanently ceased the production of Hydrocarbons in paying quantities, as well as all plants, pipelines, personal property, pits, equipment, materials, appurtenances, and facilities located on or used in connection with the Properties and that Sellers have abandoned or Page 31 otherwise permanently ceased to use, have been plugged and/or abandoned, and all related salvage, site clearance, and surface restoration operations have been completed, in accordance with Applicable Laws, and all costs and expenses incurred in connection therewith have been paid in full. None of the Wells has been plugged and abandoned. 6.2.15 Hydrocarbon Marketing. Except as identified in Exhibit C, there are no calls on production, options to purchase, or similar rights in effect with respect to any portion of the Hydrocarbons allocable to the Assets, and all contracts for the sale of Hydrocarbons produced from the Assets are terminable without penalty on no more than thirty (30) days' prior notice. Each Seller is currently receiving the prices provided for under such sales contracts with respect to the Hydrocarbons. All proceeds from the sale of Hydrocarbons attributable to the interests in the Assets of each Seller have been and are being disbursed to such Seller under appropriate division orders, transfer orders, or similar documents signed by or otherwise binding on such Seller, and no portion of any such proceeds is being held in suspense, subject to a claim for refund by the purchaser, used as an offset or as collateral for other obligations (whether disputed or undisputed), or otherwise not being paid to any Seller as it becomes due in the ordinary course of business. 6.2.16 Payment of Expenses; Commitments. Each Seller has paid its respective proportionate share of all amounts owed by Sellers in connection with the Assets for which Sellers have received invoices from the operator(s) thereof, and there are no outstanding calls or payments due from any Seller under the terms of the Existing Contracts or otherwise with respect to the Assets. Exhibit H contains a true and complete list and description, as of the date of execution of this Agreement, of all authorities for expenditures, plans of exploration and/or development, and other commitments as to which Sellers have become obligated regarding drilling, reworking, or other operations or other capital expenditures on or relating to the Assets which were not completed prior to the date of this Agreement. There are no express obligations to drill additional Hydrocarbon wells or engage in other operations on the Properties that are binding on any Seller, except as identified on Exhibit H and except for drilling obligations arising under offset well provisions of, or implied covenants under, the Leases, and operations proposed under the Existing Contracts that allow the parties thereto to elect whether to participate. There are no material operations on the Assets with respect to which any Seller has become a non-consenting party. 6.2.17 Areas of Mutual Interest, Etc. Except as set forth in any agreement identified or referred to in Exhibit A or C, the Assets are not subject to any contract containing an area of mutual interest, maintenance of uniform interest, "before payout" or "after payout" reversion or conversion, or other provision under which Sellers or Purchaser may be obligated to make assignments to third Persons of interests in any Asset after the Effective Time. 6.2.18 No Bankruptcy. There are no bankruptcy, insolvency, reorganization, or arrangement proceedings pending, being contemplated by, or, to each Seller's knowledge, threatened against any Seller or any Affiliate that controls any Seller. Page 32 6.2.19 Insurance. Each Seller has paid all premiums required under, and is otherwise in compliance with, the terms of all insurance policies or self-insurance programs obtained by Sellers with respect to the Assets, all of which policies or programs, or renewals thereof, are as of the date of execution of this Agreement, in full force and effect. 6.3 Knowledge.

Such survival does not obligate any Party to make any further representation or warranty after the Closing Date, or to cause any representation or warranty made hereunder to remain true and correct after the Closing Date. 13.3.3 Except to the extent otherwise provided in Article 15 with respect to taxes, neither Purchaser nor Sellers shall be entitled to seek indemnification from the other Party with respect to the inaccuracy in or breach of any representation or warranty made by such Party hereunder unless the Party seeking indemnification gives written notice of the alleged inaccuracy or breach to the Party from whom indemnification is sought no later than the 365th day after the Closing Date. Except to the extent otherwise provided in Article 15 with respect to taxes, and except as provided hereinafter, neither Purchaser nor Sellers shall be entitled to seek indemnification from the other Party with respect to the breach or default in the performance by such Party of any covenant or agreement of such Party contained in this Agreement unless the Party seeking indemnification gives written notice of the alleged breach or default to the Party from whom indemnification is sought no later than the 365th day after the Closing Date. Except as provided hereinafter, Purchaser shall not be entitled to seek indemnification from any Seller under the terms of clause (a) or clause (b) of Section 13.3.6 unless Purchaser gives written notice of the claim for indemnification to Sellers no later than the 365th day after the Closing Date.

The deadlines for asserting claims for indemnification specified in the preceding two sentences of this Section 13.3.3 shall be referred to herein as the "Survival Dates." Except as otherwise provided in this Agreement, the sole and exclusive remedies of Purchaser with respect to Title Defects, Casualty Losses, and Environmental Defects shall be as stated in Articles 3, 4, and 5, and in no event shall any other provision of this Agreement entitle Purchaser to any other remedy with respect to Title Defects, Casualty Losses, or Environmental Defects. 13.3.4 If the Closing occurs, Purchaser shall assume and agrees to pay, perform, and discharge any and all Assumed Obligations (as hereinafter defined).

PURCHASER'S OBLIGATIONS UNDER SECTION 13.3.4 AND THE OBLIGATIONS OF THE INDEMNIFYING PARTY UNDER SECTIONS 13.3.5 AND 13.3.6 SHALL APPLY REGARDLESS OF THE FAULT OR NEGLIGENCE (OTHER THAN THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF THE OTHER PARTY, INCLUDING STRICT OR STATUTORY LIABILITY OF THE OTHER PARTY UNDER ANY APPLICABLE LAW. 13.5 Method of Asserting Claims. All claims for indemnification under this Agreement shall be asserted and resolved as follows; provided that the provisions of Sections 13.5 and 13.6 shall be covenants and not conditions to the defense and indemnity obligations to which they apply: 13.5.1 If any claim is asserted, whether by a third party (a "Third Party Claim") or by the other Party hereto (a "Non-Third Party Claim"), for which a Party providing indemnification (the "Indemnifying Party") would be liable to a Party or any of its officers, directors, employees, agents or representatives entitled to indemnification hereunder (collectively, the "Indemnified Party"), the Indemnified Party shall promptly notify the Indemnifying Party of such claim, specifying the nature of such claim and the amount or the estimated amount thereof to the extent then feasible (which estimate shall not be conclusive of the final amount of such claim) (the "Claim Notice"). Page 47 13.5.2 Upon its receipt of a timely Claim Notice for a Third Party Claim, the Indemnifying Party shall have thirty (30) days from its receipt of such Claim Notice (the "Notice Period") to notify the Indemnified Party (i) whether it disputes its liability to the Indemnified Party hereunder with respect to such Third Party Claim; and (ii) if it does not dispute such liability, whether it desires, at its sole cost and expense, to defend the Indemnified Party against such Third Party Claim; provided, however, that the Indemnified Party is hereby authorized, prior to and during the Notice Period, to file any motion, answer, or other pleading, submission or document which it shall deem necessary or appropriate to protect its interests. If the Indemnifying Party notifies the Indemnified Party within the Notice Period that it does not dispute such liability and desires to defend against such Third Party Claim, then, except as hereinafter provided, the Indemnifying Party shall have the right to defend such Third Party Claim by appropriate proceedings, which proceedings shall be promptly settled or prosecuted to a final conclusion, in such a manner as to avoid any risk of the Indemnified Party becoming subject to liability. If the Indemnified Party desires to participate in, but not control, any such defense or settlement, it may do so at its own cost and expense. If the Indemnifying Party disputes its liability with respect to such Third Party Claim, or elects not to defend such Third Party Claim, whether by not giving timely notice as provided above or otherwise, the Indemnified Party shall have the right, but not the obligation, to defend against such Third Party Claim, and the amount of any such Third Party Claim, or if the same be contested by the Indemnifying Party or by the Indemnified Party, then that portion thereof as to which such defense is unsuccessful, shall be conclusively deemed to be a liability of the Indemnifying Party hereunder. 13.5.3 Upon receipt of a timely Claim Notice involving a Non-Third Party Claim, the Indemnified Party and the Indemnifying Parties shall meet and use their respective best efforts to agree on the validity and the amount of the Non-Third Party Claim covered by the Claim Notice. If, within thirty (30) days after the Indemnifying Party's receipt of such Claim Notice, the Parties cannot agree on the validity and the amount of the Non-Third Party Claim, the validity and the amount of the Non-Third Party Claim shall be determined by arbitration as provided below in Section 13.5.4. 13.5.4 All disputes between Sellers and Purchaser with respect to any matter relating to indemnification under this Agreement shall be determined by arbitration using the procedure for determining the arbitrator and other procedures for the arbitration contained in Section 3.9 of this Agreement, which provisions are incorporated herein mutadis mutandis. 13.6 Payment. Payments under this Article 13 and under any other indemnity provision of this Agreement shall be made as follows: 13.6.1 If the Indemnifying Party is required to make any payment hereunder, the Indemnifying Party shall promptly pay the Indemnified Party the amount so determined. If there should be a dispute as to the amount or manner of determination of any indemnity obligation owed hereunder, the Indemnifying Party shall nevertheless pay when due such portion, if any, of the obligation as shall not be subject to dispute. The difference, if any, between the amount of the obligation ultimately determined as properly payable hereunder and the portion, if any, theretofore paid shall bear interest at the Agreed Rate. Upon the payment in full of any Page 48 claim, the Indemnifying Party shall be subrogated to the rights of the Indemnified Party against any person or other entity with respect to the subject matter of this claim. 13.6.2 If all or part of any indemnification obligation under this Agreement is not paid when due upon resolution of the claim, then the Indemnifying Party shall pay upon demand to the Indemnified Party interest at the Agreed Rate on the unpaid amount of the obligation for each day from the date the amount became due until payment in full. As used herein, "Agreed Rate" means a rate per annum calculated on a 360-day basis which is equal to the lesser of (i) a rate which is two percent (2%) above the prime rate of interest of Chase Manhattan Bank, New York, New York, as announced or published by such bank from time to time (adjusted from time to time to reflect any changes in such rate determined hereunder), or (ii) the maximum rate from time to time permitted by Applicable Law. 13.7 Limitation on Damages. For the breach or non-performance by any Party of any representation, warranty, covenant, or agreement contained in this Agreement, the liability of the obligor shall be limited to direct actual damages only, except to the extent that the obligee is entitled to specific performance or injunctive relief. AS BETWEEN THE PARTIES, NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, NEITHER SELLERS NOR PURCHASER SHALL BE LIABLE TO THE OTHER PARTY AS THE RESULT OF A BREACH OR A VIOLATION OF ANY REPRESENTATION, WARRANTY, COVENANT, AGREEMENT, OR CONDITION CONTAINED IN THIS AGREEMENT FOR SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY, OR INDIRECT DAMAGES, LOST PROFITS, OR OTHER BUSINESS INTERRUPTION DAMAGES, IN TORT, IN CONTRACT, UNDER ANY INDEMNITY PROVISION, ARISING BY OPERATION OF LAW (INCLUDING, WITHOUT LIMITATION, STRICT LIABILITY), OR OTHERWISE. WITH RESPECT TO CLAIMS BY THIRD PERSONS, A PARTY MAY RECOVER FROM THE OTHER PARTY ALL COSTS, EXPENSES, OR DAMAGES (INCLUDING, WITHOUT LIMITATION, SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY, OR INDIRECT DAMAGES), LOST PROFITS, AND OTHER BUSINESS INTERRUPTION DAMAGES IN ADDITION TO ACTUAL DIRECT DAMAGES PAID OR OWED TO ANY SUCH THIRD PERSON IN SETTLEMENT OR SATISFACTION OF CLAIMS AS TO WHICH THE RELEVANT PARTY IS ENTITLED TO INDEMNIFICATION HEREUNDER. 13.8 Recording. As soon as practicable after the Closing, Purchaser shall file and record all counterparts of the General Assignment in the appropriate counties and, if necessary, with all relevant Governmental Bodies, and provide Sellers, at its expense, with copies of all recorded counterparts of the General Assignment. 13.9 Cooperation and Further Assurances. After the Closing, Sellers and Purchaser agree to take such further actions and to execute, acknowledge, and deliver all such further documents as are necessary or useful in carrying out the purposes of this Agreement or of any document delivered pursuant to this Agreement, including, but not limited to, the execution of state change of operator forms and other required state regulatory filings. Each Party also agrees to cooperate with each other by providing reasonable information which Page 49 may be required by the other Party for the purpose of administering the Assets and preparing or reviewing the Post-Closing Adjustment Statement. 14. TERMINATION 14.1 Right of Termination. This Agreement may be terminated at any time at or prior to the Closing only: 14.1.1 by mutual consent of the Parties; 14.1.2 by the Party not in material breach or material default of its obligations under this Agreement if, prior to the Closing Date, the other Party is in material breach or material default of its obligations under this Agreement; 14.1.3 by either Party pursuant to the provisions of Section 3.8, if applicable; 14.1.4 by Purchaser if the Closing does not occur because (i) any of the conditions contained in Article 11 hereof is not fulfilled by Sellers or waived by Purchaser on or before the Closing Date, and (ii) all of the conditions set forth in Article 10 hereof have been fulfilled on or before the Closing Date; 14.1.5 by Sellers if the Closing does not occur because (i) any of the conditions contained in Article 10 hereof is not fulfilled by Purchaser or waived by Sellers on or before the Closing Date, and (ii) all of the conditions set forth in Article 11 hereof have been fulfilled on or before the Closing Date; 14.1.6 by Purchaser pursuant to the terms of Section 1.1.3 or Section 8.10, if applicable; or 14.1.7 by Sellers pursuant to the terms of Section 2.3.1, if applicable. 14.2 Effect of Termination. If this Agreement is terminated pursuant to Section 14.1 above, this Agreement shall become void and of no further force or effect (except for the provisions of Sections 9.1, 13.7, 16.10, and this Section 14.2, which shall continue in full force and effect). If this Agreement is terminated pursuant to Section 14.1.1, Section 14.1.3, Section 14.1.6, or Section 14.1.7, neither Party shall have any further liability to the other Party as the result of such termination. If Sellers terminate this Agreement pursuant to Section 14.1.2 or Section 14.1.5 as the result of Purchaser's failure to fulfill any condition set forth in Article 10, then in addition to such right of termination, the sole and exclusive remedy of Sellers with respect to such breach or default by Purchaser or failure by Purchaser to fulfill such conditions shall be the right to retain the Performance Deposit in accordance with Section 2.3 hereof. If Purchaser terminates this Agreement pursuant to Section 14.1.2 or Section 14.1.4 as the result of Sellers' failure to fulfill any condition set forth in Article 11, then in addition to such right of termination and the right to the return of the Performance Deposit under Section 2.3 hereof, Purchaser shall be entitled to pursue any and all remedies available to Purchaser at law or in equity (but not including specific performance); provided, however, that any damages recovered by Purchaser from Sellers with respect to such breach or default by Sellers or such failure by Sellers to fulfill such conditions shall be limited to direct, actual damages in an amount not to exceed the amount of the Performance Deposit. Notwithstanding anything to Page 50 the contrary contained in this Agreement, upon any termination of this Agreement pursuant to Section 14.1, Sellers shall be free immediately to enjoy all rights of ownership of the Assets and to sell, transfer, encumber, or otherwise dispose of the Assets to any party without any restriction under this Agreement; and Purchaser shall be liable for all actual, incidental, and consequential damages (including, without limitation, lost profits) if it attempts to interfere in any way with any such enjoyment or action by Sellers; provided that the institution of a lawsuit for actual, incidental, or consequential damages (including, without limitation, lost profits) by Purchaser (including, without limitation, a lawsuit based on a claim that Sellers breached Section 8.11) shall not be deemed to be an attempt to interfere with such enjoyment or action by Sellers, as long as Purchaser, upon written request by Sellers, provides reasonable assurances to any party (as designated by Sellers) contemplating the purchase from Sellers of the Assets or any portion thereof that Purchaser claims no interest in the Assets by virtue of a right to enforce specific performance under this Agreement and shall waive any rights it may have to enjoin the sale of the Assets to such party and to institute any actions at law against such party with respect to tortious interference with its rights under this Agreement, unless Purchaser has reasonable cause to believe that the party in question has tortiously interfered with its rights under this Agreement. 15. TAXES 15.1 Apportionment of Ad Valorem and Property Taxes. All ad valorem taxes, real property taxes, Personal Property taxes, and similar tax obligations (the "Property Taxes") with respect to the Assets for the tax period in which the Effective Date occurs shall be apportioned, based on the Effective Date, between Sellers, on the one hand, and Purchaser, on the other hand, and, if already paid by Sellers, an appropriate increase in the Purchase Price shall be made pursuant to Section 2.4.5. If such Property Taxes are not already paid, but the tax liability is known or can be reasonably estimated, Sellers' portion of such Property Taxes shall be credited to Purchaser's account pursuant to Section 2.4.11. Purchaser shall pay or cause to be paid to the taxing authorities all Property Taxes of which it has knowledge not already paid relating to the tax period in which the Effective Date occurs and if appropriate adjustments to the Purchase Price pursuant to Section 2.4 were not made at the Closing or in connection with the Post-Closing Adjustment Statement, Purchaser shall invoice Sellers (with copies of applicable tax bills and assessments to confirm same) for Sellers' apportioned shares of such Property Taxes, and Sellers shall pay the same within thirty (30) days of receipt of said notice. Purchaser shall defend, indemnify, and hold Sellers harmless with respect to the payment of such Property Taxes of which Purchaser has knowledge and which Purchaser is obligated to pay to the applicable taxing authorities (including any interest or penalties assessed thereon), provided Sellers pay their respective shares (as apportioned hereunder) within thirty (30) days of being properly invoiced (with accompanying documents to support the invoice) by Purchaser. For the tax period in which the Effective Date occurs, Sellers agree (i) to forward immediately to Purchaser copies of all Property Tax reports and returns received by Sellers after the Closing and (ii) to provide Purchaser with appropriate information which is necessary for Purchaser to file any required Property Tax reports and returns. All tax apportionments determined under this Section 15.1 and Section 15.2 shall be deemed a final settlement of Property Taxes between the Parties. Notwithstanding the foregoing, Sellers or Purchaser may contest with the appropriate taxing authority the amount of or liability for any Property Tax apportioned to it pursuant to this Section 15.1. The Party pursuing the contest shall indemnify the other Party from and against all Costs incurred by the other Party in connection with the contest, and upon final settlement or resolution of Page 51 the contest, the economic burden of the contested tax shall be adjusted among the Parties in a manner consistent with the intent of this Section 15.1. 15.2 Taxes Paid for Others. To the extent Purchaser has a right to do so, Purchaser agrees to withhold from future income distributions to royalty owners, overriding royalty interest owners, and other production burden holders as to the Assets amounts sufficient to reimburse Sellers for various taxes (e.g., Property Taxes, severance, environmental excise, etc.) paid by Sellers on behalf of such interest holders while Sellers owned the Assets (which shall include withholdings for co-working interest owners when Sellers have paid such owners' taxes and have not previously collected such taxes through joint interest billings). Sellers will provide Purchaser with sufficient documentation to allow Purchaser to confirm amounts to be withheld, and each Seller, severally according to its ownership interest in the Assets and not jointly, will indemnify and hold Purchaser harmless from liability for deducting such sums as directed by Sellers. Purchaser agrees promptly to forward to Sellers such sums which are withheld pursuant to this Section 15.2. 15.3 Sales Taxes. Purchaser shall pay, or cause to be paid, all sales, use, transfer, and similar taxes, if any, resulting from the sale and transfer of the Assets to Purchaser hereunder (including without limitation, all applicable conveyance, transfer and recording fees, and real estate transfer stamps or taxes imposed on the transfer of the Assets pursuant to this Agreement), and shall prepare and file all tax returns required to be filed with respect to such taxes. 15.4 Other Taxes. All production, severance, excise, and other similar taxes that are based upon production of, or income or revenues from, Hydrocarbons attributable to the Assets prior to the Effective Date shall be paid by Sellers, and all such taxes relating to such production on or after the Effective Date shall be paid by Purchaser. The Party responsible for payment of such taxes shall prepare and file all tax returns required to be filed in respect thereof. This Section 15.4 shall not apply to any tax to the extent specifically otherwise provided elsewhere in this Agreement. 15.5 Cooperation. Each Party shall cooperate with the other Party and provide the other Party with all information in its possession or to which it has access which may be reasonably required by the other Party in connection with the preparation of any tax return relating to the Assets, the audit or examination of any such returns by any tax authority, and the determination of or contest of any tax relating to the Assets. Notwithstanding anything to the contrary in this Agreement, neither Party shall be required at any time to disclose to the other Party any tax returns or other confidential tax information except to the extent required by Applicable Law or court order. 15.6 Tax Indemnity. Each Seller, severally according to its ownership interest in the Assets and not jointly, shall indemnify and hold harmless Purchaser, and Purchaser shall indemnify and hold harmless Sellers, in each case with respect to the payment of any taxes, including any interest or penalties assessed thereon, for which the indemnifying Party is responsible pursuant to the provisions of this Article 15.

Sellers shall have the right to utilize all or part of the Assets as part of a tax deferred exchange pursuant to Section 1031 of the IRC and applicable state and local tax laws. In connection with an exchange, and notwithstanding the terms of Section 16.4, all or part of the rights of Sellers under this Agreement may be assigned, without the need for Purchaser's consent, to an intermediary, escrow agent, trustee, or other exchange accommodation party, provided that such assignment shall not relieve Sellers of their obligations to Purchaser hereunder. Purchaser shall cooperate with Sellers in effecting such an exchange, including, without limitation, the execution of escrow instructions and other instruments, provided that: (i) the acquisition and exchange of any exchange property shall not impose upon Purchaser any additional financial obligation other than as set out in this Agreement; (ii) Purchaser shall have no obligation to become a holder of record title to any exchange property; (iii) each Seller, severally according to its ownership interest in the Assets and not jointly, shall indemnify and hold Purchaser harmless from any and all Costs which Purchaser incurs or to which Purchaser may be exposed as a result of Purchaser's participation in the contemplated exchange, including reasonable attorneys' fees and costs of defense; (iv) the Closing shall not be delayed or affected by reason of such exchange nor shall the consummation or accomplishment of such exchange be a condition precedent or condition subsequent to Sellers' obligations under this Agreement; (v) Purchaser shall not, by this Agreement or acquiescence to such exchange, have its rights under this Agreement affected or diminished in any manner; and (vi) Purchaser shall not, by this Agreement or acquiescence to such exchange, be responsible for compliance with or deemed to have warranted to Sellers that such exchange in fact complies with Section 1031 of the IRC or any state or local tax law. If any exchange contemplated by Sellers should fail to occur, for whatever reason, the sale of the Assets shall nonetheless be consummated as provided herein. 16.19 Data.
