(F) Shareholder or member resolutions, as applicable, of the Company and Seller, certified by the secretary or other appropriate officer of the Company and Seller, authorizing the execution and performance of this Agreement and the transactions contemplated hereby; and

(G) Such other documents as Seller may reasonably request.

3.3 Delivery by Buyer. At Closing, Buyer shall deliver to Seller:

(A) The Purchase Price set forth in the Closing Adjustment Statement by wire transfer in immediately available funds, less the Deposit; and

(B) An executed Closing Adjustment Statement.

3.4 Further Cooperation. At the Closing and thereafter as may be necessary, Seller and Buyer shall execute and deliver such other instruments and documents and take such other actions as may be reasonably necessary to evidence and effectuate the transactions contemplated by this Agreement.

4. ACCOUNTING ADJUSTMENTS.

4.1 Closing Adjustments. With respect to matters that can be determined as of the Closing, Seller shall prepare, in accordance with the provisions of this Article 4, a statement (the “Closing Adjustment Statement”) with relevant supporting information setting forth each adjustment to the Base Purchase Price submitted by Seller. Seller shall submit the Closing Adjustment Statement to Buyer, together with all records or data supporting the calculation of amounts presented on the Closing Adjustment Statement, no later than three (3) business days prior to the scheduled Closing Date. Prior to the Closing, Buyer and Seller shall review the adjustments proposed by Seller in the Closing Adjustment Statement. Agreed adjustments shall be taken into account in computing any adjustments to be made to the Base Purchase Price at the Closing. When available, actual figures will be used for the adjustments at Closing. To the extent actual figures are not available, estimates shall be used subject to final adjustments as described in Section 4.4 below.

4.2 Strapping and Gauging. Seller caused the Oil and Gas in the storage facilities located on, or utilized in connection with, the Leases to be measured, gauged or strapped as of the Effective Time. Seller caused the production meter charts (or if such do not exist, the sales meter charts) on the pipelines transporting Oil and Gas from the Leases to be read as of such time. The Oil and Gas in such storage facilities above six inches or through the meters on the pipelines as of the Effective Time shall be allocated to the Seller and shall be valued based on the price actually paid for Oil and Gas produced from the Oil and Gas Properties for the month prior to the Effective Time, and the Oil and Gas placed in such storage facilities after the Effective Time and production upstream of the aforesaid meters shall belong to the Company and become part of the Oil and Gas Properties. Buyer or Buyer’s representative shall have the option to witness the gauging by Seller. To the extent, but only to the extent, the Company does not receive the sales proceeds from the sale of such stored Oil and Gas prior to Closing, the value of such shared Oil and Gas shall be an upward adjustment to the Base Purchase Price as provided in Section 2.4(A). This provision should not apply to any Oil and Gas Properties that are not operated by the Company. There shall be no settlement for Stock in Tanks on non-operated Oil and Gas Properties.

4.3 Taxes.

(A) Property Taxes. All ad valorem taxes, real property taxes, personal property taxes and similar obligations assessed on the Oil and Gas Properties (“Property Taxes”) shall be apportioned as of the Effective Time between Buyer and Seller. Buyer shall cause the Company to file all required reports and returns incident to Property Taxes which are due on or after the Closing, and the Company shall pay or cause to be paid to the taxing authorities all such taxes reflected on such reports and returns. The Post-Closing

Adjustment Statement shall settle all liability for Property Taxes, using estimates based on previous assessments to the extent current assessments are not known.

(B) Sales Taxes, Filing Fees, Etc. The Base Purchase Price is net of any sales taxes or other transfer taxes. Buyer shall be liable for any sales tax or other transfer tax as well as any applicable conveyance, transfer and recording fees. If Seller is required by applicable state law to report and pay these taxes or fees, Buyer shall promptly reimburse Seller in full payment of the invoice.

(C) Severance Taxes. All production, severance or excise taxes, conservation fees and other similar taxes or fees (other than income taxes) payable on a current basis with respect to Oil and Gas produced and sold from the Assets (“Severance Taxes”) shall be allocated to Seller to the extent the production on which such taxes are based occurs prior to the Effective Time and shall be allocated to Buyer to the extent such production occurs after the Effective Time.

4.4 Post-Closing Adjustments.

(A) A post-closing adjustment statement (the “Post-Closing Adjustment Statement”) based on the actual income and expenses shall be prepared and delivered by Seller to Buyer within ninety (90) days after the Closing, proposing further adjustments to the calculation of the Purchase Price based on the information then available. Seller or Buyer, as the case may be, shall be given access to and shall be entitled to review and audit the other Party’s records pertaining to the computation of amounts claimed in such Post-Closing Adjustment Statement.

(B) Within thirty (30) days after receipt of the Post-Closing Adjustment Statement, Buyer shall deliver to Seller a written statement describing in reasonable detail its objections (if any) to any amounts or items set forth on the Post-Closing Adjustment Statement. If Buyer does not raise objections within such period, then the Post-Closing Adjustment Statement shall become final and binding upon the Parties at the end of such period.

(C) If Buyer raises objections, the Parties shall negotiate in good faith to resolve any such objections. If the Parties are unable to resolve any disputed item within thirty (30) days after Buyer’s receipt of the Post-Closing Adjustment Statement, any disputed accounting item shall be submitted to a nationally recognized independent accounting firm mutually agreeable to the Parties who shall be instructed to resolve such disputed item within thirty (30) days. The resolution of disputes by the accounting firm so selected shall be set forth in writing and shall be conclusive, binding and non-appealable upon the Parties with respect to the accounting matters submitted and the Post-Closing Adjustment Statement shall become final and binding upon the Parties on the date of such resolution. The fees and expenses of such accounting firm shall be paid one-half by Buyer and one-half by Seller.

(D) After the Post-Closing Adjustment Statement has become final and binding on the Parties, Seller or Buyer, as the case may be, shall pay to the other such sums as are due to settle accounts between the Parties due to differences between the estimated Purchase Price

paid pursuant to the Closing Adjustment Statement and the actual Purchase Price set forth on the Post-Closing Adjustment Statement.

4.5 Suspended Funds. At the Closing, Seller shall provide to Buyer a listing showing all third party proceeds from production attributable to the operated Leases which are currently held in suspense and shall transfer to Buyer all of those suspended proceeds. The Company shall be responsible for proper distribution of all the suspended proceeds, to the extent so identified by Seller, to the parties lawfully entitled to them and any claims related thereto, and the Company hereby agrees to indemnify, defend and hold harmless Seller from and against any and all claims, liabilities, losses, costs and expenses arising out of or relating to those suspended proceeds and any claims related thereto after the Effective Time. Seller shall be responsible and liable for, any claims, liabilities, losses, costs and expenses arising out of or relating to those suspended proceeds and any claims related thereto through the Closing Date and related to any suspended funds not identified by Seller as provided above.

4.6 Audit Adjustments. Seller retains all rights to adjustments resulting from any operating agreement and other audit claims asserted against third party operators on transactions occurring prior to the Effective Time (which includes Buyer, if applicable). Any credit received by Buyer pertaining to such an audit claim shall be paid to Seller within thirty (30) days after receipt.

4.7 Cooperation. Each Party covenants and agrees to promptly inform the other with respect to amounts owing under Sections 4.4 and 4.6 hereof.

5. DUE DILIGENCE: TITLE MATTERS.

5.1 General Access.

(A) During reasonable business hours, Seller and the Company agree to grant Buyer physical access to the Oil and Gas Properties and other assets of the Company to allow Buyer to conduct, at Buyer’s sole risk and expense, on-site inspections and environmental assessments of the Oil and Gas Properties and other assets of the Company. In connection with any such on-site inspections, Buyer agrees not to interfere with the normal operation of the Oil and Gas Properties and other assets of the Company and agrees to comply with all requirements of the operators of the Wells. If Buyer or its agents prepares an environmental assessment of any of the Oil and Gas Properties and other assets of the Company, Buyer agrees to keep such assessment confidential. In connection with granting such access, Buyer represents that it is adequately insured and waives, releases and agrees to indemnify the Seller and the Company against all claims for injury to, or death of, persons or for damage to operations or property arising in any way from the access afforded to Buyer hereunder or the activities of Buyer, except to the extent caused by Seller’s or the Company’s gross negligence or willful misconduct. This waiver, release and indemnity by Buyer shall survive termination of this Agreement.

(B) Upon the execution of this Agreement, Seller and the Company shall give Buyer and its representatives, employees, consultants, independent contractors, attorneys and other advisors reasonable access to the Records and other books and records of the Company during regular office hours for any and all inspections and copying.

5.2 Defensible Title. As used herein the term “Defensible Title” shall mean:

(A) As to the Oil and Gas Properties, that record title of the Company which:

(i) entitles the Company to receive not less than the interests shown in Exhibit B as the “Net Revenue Interest” of all Oil and Gas produced, saved and marketed from or allocated to the Wells, all without reduction, suspension or termination during the life of such Wells except as stated in such Exhibit; and

(ii) obligates the Company to bear a percentage of the costs and expenses relating to the maintenance and development of, and operations relating to, the Wells not greater than the “Working Interest” shown in Exhibit B (without a proportionate increase in the Net Revenue Interest), all without increase during the life of such Wells except as stated in such Exhibit; and

(B) That title of the Company to the Oil and Gas Properties is free and clear of liens, encumbrances and defects that materially and adversely affect the ownership, operation or use of the Oil and Gas Properties, except for Permitted Encumbrances.

(C) As used herein, the term “Permitted Encumbrances” shall mean any one or more of the following:

(1) Any lessor’s royalties, overriding royalties, net profits interests, carried interests, production payments, reversionary interests and similar burdens reflected in the public records, if the net cumulative effect of the burdens does not operate to reduce the Net Revenue Interest of the Company below the interests described in Exhibit B;

(2) Any increase in lessor’s royalty occasioned by the repeal or suspension of any governmental regulation providing for the reduction of royalty for wells producing below defined threshold amounts;

(3) Division orders and production sales contracts terminable without penalty upon no more than ninety (90) days notice to the purchaser;

(4) Preferential Rights and required third party consents to assignment and similar agreements with respect to which waivers or consents are obtained from the appropriate parties, or the appropriate time period for asserting any such right has expired without an exercise of the right;

(5) Materialman’s, mechanic’s, repairman’s, employee’s, contractor’s, operator’s and other similar liens or charges arising in the ordinary course of business for obligations that are not delinquent and that will be paid and discharged in the ordinary course of business, or if delinquent, that are being contested in good faith by appropriate action of which Buyer is notified in writing before Closing;

(6) All rights to consent by, required notices to, filings with, or other actions by governmental entities in connection with the sale or conveyance of oil and gas leases or interests therein if they are routinely obtained subsequent to the sale or conveyance;

(7) Easements, rights-of-way, servitudes, permits, surface leases and other rights in respect of surface operations that do not materially interfere with the oil and gas operations to be conducted on any Well or Lease;

(8) All operating agreements, unit agreements, unit operating agreements, pooling agreements and pooling designations affecting the Assets that are either (i) of record in the Company’s chain of title or (ii) reflected or referenced in the Records or (iii) included as Material Agreements on Schedule 7.1(K), to the extent the same do not decrease the Company’s Net Revenue Interests below the interests set forth on Exhibit B or increase the Company’s Working Interests above the interests set forth on Exhibit B;

(9) Conventional rights of reassignment prior to release or surrender requiring notice to the holders of the rights;

(10) All rights reserved to or vested in any governmental, statutory or public authority to control or regulate any of the Oil and Gas Properties in any manner, and all applicable laws, rules and orders of governmental authority;

(11) Defects that are defensible by possession under applicable statutes of limitation for adverse possession or for prescription;

(12) All other liens, charges, encumbrances, contracts, agreements, instruments, obligations, defects and irregularities which results in an adjustment to the Base Purchase Price under Section 5.4.

(13) All other liens, charges, encumbrances, contracts, agreements, instruments, obligations, defects and irregularities affecting the Oil and Gas Properties that individually or in the aggregate are not such as to materially interfere with or affect the operation, value or use of any of the Oil and Gas Properties and have not prevented, and cannot reasonably be expected to prevent, the Company from receiving the proceeds of production from the affected Oil and Gas Properties.

5.3 Defect Letters.

(A) Buyer may from time to time and no later than September 25, 2008, at 5:00 p.m., Central Time (the “Defect Notice Deadline”) notify Seller in writing (a “Notice”) of any matter which would cause title to all or part of the Oil and Gas Properties not to be Defensible Title (“Title Defect”). There shall be no adjustment to the Base Purchase Price unless the aggregate Title Defect Values of all Title Defects exceed two percent (2%) of the Base Purchase Price (the “Title Defect Threshold”) (such amount being a threshold, not a deductible). In order to provide Seller a reasonable opportunity to cure any Title Defects

prior to Closing, Buyer shall use reasonable efforts to provide the Notice as soon as reasonably possible after becoming aware of or making its determination of the Title Defect.

(B) In the Notice, Buyer must describe with reasonable detail each alleged Title Defect it has discovered and the steps required to cure each Title Defect, include Buyer’s reasonable estimate of the Title Defect Value attributable to each, and include all data and information in Buyer’s possession or control bearing thereon. Except for Title Defects arising by, through or under the Company, Buyer shall be deemed to have conclusively waived all Title Defects not disclosed to Seller in a Notice on or before the Defect Notice Deadline.

(C) Upon timely delivery of a Notice by Buyer:

(i) within three (3) business days after Seller’s receipt of the Title Defects Notice, Seller shall notify Buyer whether Seller agrees with Buyer’s claimed Title Defects and/or the proposed Title Defect Values therefor (“Seller’s Response”). If Seller does not agree with any claimed Title Defect and/or the proposed Title Defect Value therefor, then the Parties shall enter into good faith negotiations and shall attempt to agree on such matters;

(ii) within one (1) business day after Seller’s notice of its cure of a Title Defect, Buyer shall notify Seller whether Buyer agrees with Seller’s proposed cure of a Title Defect (“Buyer’s Response”). All actions to attempt to cure a Title Defect shall be at Seller’s expense. If Buyer does not agree with any such cure, then the Parties shall enter into good faith negotiations and shall attempt to agree on such matters;

(iii) if the Parties cannot reach agreement concerning either the existence of a Title Defect, Seller’s proposed cure of a Title Defect, or a Title Defect Value within ten (10) days after Buyer’s receipt of Seller’s Response or Seller’s receipt of Buyer’s Response, as applicable, upon either Party’s request, the Parties shall mutually agree on and employ an attorney experienced in title examination in the state where the Oil and Gas Properties are located (“Title Consultant”) to resolve all points of disagreement relating to Title Defects and Title Defect Values; provided that Seller or Buyer may elect to proceed to Closing with such Oil and Gas Property subject to the Title Defect becoming an Excluded Asset and adjust the Base Purchase Price in the amount of the Allocated Value and not submit such matter to arbitration;

(iv) if at any time any Title Consultant so chosen fails or refuses to perform hereunder, a new Title Consultant shall be chosen by the Parties. The cost of any such Title Consultant shall be borne one hundred percent (100%) by the party that does not prevail. Each Party shall present a written statement of its position on the Title Defect and/or Title Defect Value in question to the Title Consultant within five (5) days after the Title Consultant is selected, and the Title Consultant shall make a determination of all points of disagreement in accordance with the terms and

conditions of this Agreement within ten (10) business days of receipt of such position statements. The determination by the Title Consultant shall be conclusive and binding on the Parties, and shall be enforceable against any Party in any court of competent jurisdiction. If necessary, the Closing Date shall be deferred until the Title Consultant has made a determination of the disputed issues with respect thereto; provided, however, that, unless Seller and Buyer mutually agree to the contrary, the Closing Date shall not be deferred in any event for more than thirty (30) days beyond the scheduled Closing Date in Section 3.1. Once the Title Consultant’s determination has been expressed to both Parties, if applicable, Seller shall have five (5) days in which to advise Buyer in writing which of the options available to Seller under Section 5.4 that Seller elects regarding each of the Oil and Gas Properties as to which the Title Consultant has made a determination. In evaluating whether a Title Defect exists, due consideration shall be given to the length of time that the particular Oil and Gas Property has been producing Oil and Gas and whether such fact, circumstance or condition is of the type expected to be encountered in the area involved and is usual and customarily acceptable to reasonable and prudent operators, working interest owners and/or purchasers engaged in the business of the exploration, development, and operation of oil and gas properties.

5.4 Effect of Title Defect.

(A) In the event Buyer provides Seller with a timely Notice and the Title Defects are valid and exceed the Title Defect Threshold, for those Title Defects not cured by Closing, Seller may, at its sole discretion:

(i) adjust the Base Purchase Price in the amount of the Title Defect Value of the Oil and Gas Property to which such Title Defect relates and proceed to Closing on all Oil and Gas Properties; or

(ii) proceed with (a) Closing on those Oil and Gas Properties not affected by the valid Title Defects and such Oil and Gas Properties to which a Title Defect relates but for which Seller has elected to proceed to Closing with an adjustment of the Base Purchase Price in the amount of the Title Defect Value of such Oil and Gas Properties, and (b) defer Closing on those other Oil and Gas Properties to which a Title Defect relates and for which Seller has elected to attempt to cure such Title Defect and to not proceed to Closing, for which Buyer shall place into escrow an amount equal to the Allocated Values of the Oil and Gas Properties affected by the valid Title Defects, which withheld amount shall be paid to Seller when the Oil and Gas Property affected by any valid Title Defect is cured or the Title Defect is waived by Buyer and the affected Oil and Gas Property is conveyed from Seller to Buyer. If neither of the above occurs and if Seller later determines it will not cure a Title Defect on or before thirty (30) days from the Closing Date, the amount in the escrow account attributable to such Title Defect will be returned to Buyer and such Oil and Gas Property affected by such Title Defect shall be deemed an Excluded Asset and be transferred to Seller or Seller’s designee pursuant to Section 1.2.

(B) The diminution in value of an Oil and Gas Property attributable to a valid Title Defect (the “Title Defect Value”) notified in a Notice shall be determined by the following:

(i) if the valid Title Defect asserted is that the actual Net Revenue Interest attributable to the producing or valued formation in any Oil and Gas Property is less than that stated in the applicable Exhibit, then the Title Defect Value is the product of the Allocated Value attributed to the affected formation(s) in such Oil and Gas Property, multiplied by a fraction, the numerator of which is the difference between the Net Revenue Interest set forth in the applicable Exhibit and the actual Net Revenue Interest, and the denominator of which is the Net Revenue Interest stated in the applicable Exhibit; or

(ii) if the valid Title Defect represents an obligation, encumbrance, burden or charge upon the affected Oil and Gas Property (including any increase in Working Interest for which there is not a proportionate increase in Net Revenue Interest), the amount of the Title Defect Value is to be determined by taking into account the Allocated Value of such Oil and Gas Property, the portion of the Oil and Gas Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the affected Oil and Gas Property, and the Title Defect Values placed upon the Title Defect by Buyer and Seller.

(iii) Notwithstanding the above, in no event shall the total of the Title Defect Values related to a particular Oil and Gas Property exceed the Allocated Value of such Oil and Gas Property.

(C) If the aggregate value of (i) the Base Purchase Price adjustment for Title Defect Values plus (ii) the Allocated Value of Oil and Gas Properties which are excluded in lieu of cure or adjustment equals or exceeds ten percent (10%) of the Base Purchase Price, then by notice delivered prior to the Closing either Party may terminate this Agreement and neither Party shall have any further obligation to conclude the transaction contemplated by this Agreement.

5.5 Consents. Seller shall cause the Company to use its best efforts to obtain all required consents. If Buyer discovers other affected Oil and Gas Properties during the course of Buyer’s due diligence activities, Buyer shall notify Seller immediately and Seller shall cause the Company to use its best efforts to obtain such consents prior to Closing.

Except for consents and approvals which are customarily obtained post-Closing, if a necessary consent to assign any Lease has not been obtained as of the Closing, then (i) the portion of the Oil and Gas Properties for which such consent has not been obtained shall become an Excluded Asset conveyed to Seller or Seller’s designee at the Closing, (ii) the Allocated Value for that Oil and Gas Property shall not be paid to Seller, and (iii) Seller shall use best efforts to obtain such consent as promptly as possible following Closing. If such consent has been obtained as of the date on which the Post-Closing Adjustment Statement becomes final, Seller shall convey the affected Oil and Gas

Property to the Company effective as of the Effective Time and Buyer shall pay Seller the Allocated Value of the affected Oil and Gas Property, less any proceeds from the affected Oil and Gas Property received by Seller attributable to the period of time after the Effective Time (calculated in accordance with Section 2.3). If such consent has not been obtained or has not been waived by Buyer as of the date on which the Post-Closing Adjustment Statement becomes final, Seller shall elect either to (i) challenge in court the enforceability of such consent right, in which event the affected Oil and Gas Property shall be assigned to Seller as an Excluded Asset and a portion of the Purchase Price equal to the Allocated Value of the affected Oil and Gas Property shall be withheld by Buyer until such legal challenge is finally resolved by settlement or non-appealable court order, after which Seller shall convey the affected Oil and Gas Property to the Company under the terms of this Agreement and Buyer shall pay the Allocated Value for such Oil and Gas Property, less any proceeds received by Seller attributable to such Oil and Gas Property for the period from and after the Effective Time (calculated in accordance with Section 2.3) or (ii) deem the affected Oil and Gas Property an Excluded Asset and the Base Purchase Price shall be reduced by an amount equal to the Allocated Value of the affected Oil and Gas Property (with such adjustment being an “Exclusion Adjustment”). Buyer shall reasonably cooperate with Seller in obtaining any required consent including providing assurances of reasonable financial conditions, but Buyer shall not be required to expend funds or make any other type of financial commitments a condition of obtaining such consent.

6. ENVIRONMENTAL ASSESSMENT.

6.1 Physical Condition of the Oil and Gas Properties.

(A) Buyer acknowledges that the Oil and Gas Properties have been used for oil and gas drilling and production operations and possibly for the storage and disposal of waste materials or hazardous substances related to standard oil field operations. Physical changes in or under the Oil and Gas Properties or adjacent lands may have occurred as a result of such uses. The Oil and Gas Properties also may contain previously plugged and abandoned wells, buried pipelines, storage tanks and other equipment, whether or not of a similar nature, the locations of which may not now be known by Seller or be readily apparent by a physical inspection of the Oil and Gas Properties. Upon consummation of the Closing Buyer shall be deemed to have assumed the risk of expense, claim, damage or liability arising from any such matter referred to in this section, including without limitation the risk that the Oil and Gas Properties may contain waste or contaminants and that adverse physical conditions, including the presence of waste or contaminants, may not have been revealed by Buyer’s investigation. Upon consummation of the Closing the Company shall retain all responsibility and liability related to disposal, spills, waste or contamination on or below the Oil and Gas Properties.

(B) In addition, Buyer acknowledges that some oil field production equipment located on the Oil and Gas Properties may contain asbestos and/or naturally-occurring radioactive material (“NORM”). In this regard, Buyer expressly understands that NORM may affix or attach itself to inside of wells, materials and equipment as scale or in other forms, and that wells, materials and equipment located on the Oil and Gas Properties described herein may contain NORM and that NORM-containing materials may be buried or have been otherwise disposed of on the Oil and Gas Properties. Buyer also expressly understands that special procedures may be required for the removal and disposal of

asbestos and NORM from the Oil and Gas Properties where it may be found, and that upon consummation of the Closing the Company shall be deemed to have retained all liability when such activities are performed

6.2 Inspection and Testing.

(A) Prior to Closing, Buyer shall have the right, at its sole cost and risk, to review Seller’s or the Company’s Phase I environmental assessments of the Oil and Gas Properties, if any exist, and to conduct any further environmental assessment of the Oil and Gas Properties it deems appropriate, to the extent that Seller or the Company has the authority to grant such right to Buyer. Buyer shall immediately provide to Seller any data obtained from such assessments, including any reports and conclusions. Seller, the Company and Buyer shall keep all information relating to such assessments strictly confidential whether or not Closing occurs, except as may be required pursuant to any Environmental Laws.

(B) Buyer waives and releases all claims against Seller, the Company, their Affiliates, and each of their respective directors, officers, employees, agents, and other representatives and their successors and assigns (collectively, the “Seller’s Group”), for injury to or death of persons, or damage to property, arising in any way from the exercise of rights granted to Buyer in Section 6.2(A) above or the activities of Buyer or its employees, agents or contractors on the Oil and Gas Properties pursuant to Section 6.2(A) above. EXCEPT TO THE EXTENT CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE SELLER’S GROUP, BUYER SHALL INDEMNIFY THE SELLER’S GROUP AGAINST AND HOLD THE MEMBERS OF THE SELLER’S GROUP HARMLESS FROM ANY AND ALL REASONABLE LOSS, COST, DAMAGE, EXPENSE OR LIABILITY, INCLUDING REASONABLE ATTORNEY’S FEES, WHATSOEVER ARISING OUT OF (I) ANY AND ALL STATUTORY OR COMMON LAW LIENS OR OTHER ENCUMBRANCES FOR LABOR OR MATERIALS FURNISHED IN CONNECTION WITH SUCH TESTS, SAMPLINGS, STUDIES OR SURVEYS AS BUYER MAY CONDUCT WITH RESPECT TO THE OIL AND GAS PROPERTIES; AND (II) ANY INJURY TO OR DEATH OF PERSONS OR DAMAGE TO PROPERTY OCCURRING IN, ON OR ABOUT THE OIL AND GAS PROPERTIES AS A RESULT OF SUCH EXERCISE OR ACTIVITIES.

(C) “Environmental Laws” means all applicable local, state, and federal laws, rules, regulations, and orders regulating or otherwise pertaining to: (i) the use, generation, migration, storage, removal, treatment, remedy, discharge, release, transportation, disposal, or cleanup of pollutants, contamination, hazardous wastes, hazardous substances, hazardous materials, toxic substances or toxic pollutants; (ii) surface waters, ground waters, ambient air and any other environmental medium on or off any Lease; or (iii) the environment, habitat protection or health and safety-related matters; including the following as from time to time amended and all others whether similar or dissimilar: the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended by the Superfund Amendments and Reauthorization Act of 1986, the Resource Conservation and Recovery Act of 1976, as amended by the Used Oil Recycling Act of 1980, the Solid Waste Disposal Act Amendments of 1980, and the Hazardous and Solid Waste Amendments of 1984, the Hazardous Materials Transportation Act, the Toxic

Substance Control Act, the Clean Air Act, the Clean Water Act, the Safe Drinking Water Act, the National Environmental Policy Act, the Endangered Species Act, the Oil Pollution Act of 1990, and all regulations promulgated pursuant thereto.

6.3 Notice of Adverse Environmental Conditions. No later than the Defect Notice Deadline, Buyer shall notify Seller in writing of any Adverse Environmental Condition with respect to the Oil and Gas Properties. Such notice shall describe in reasonable detail the Adverse Environmental Condition and include the estimated Environmental Defect Value attributable thereto (the “Environmental Defect Notice”) based on an estimate of the cost to Remediate the Adverse Environmental Condition. There shall be no adjustment to the Base Purchase Price unless the aggregate Environmental Defect Values of all Adverse Environmental Conditions exceeds one percent (1%) of the Base Purchase Price (the “Environmental Defect Threshold”) (such amount being a threshold, not a deductible). The “Environmental Defect Value” attributable to any Adverse Environmental Condition shall be the estimated amount (net to the Company’s interest) of all reasonable costs and claims necessary to Remediate the Adverse Environmental Conditions, as reasonably determined and estimated by Buyer. The term “Adverse Environmental Condition” means (i) the failure of the Oil and Gas Properties to be in material compliance with all applicable Environmental Laws; (ii) the Oil and Gas Properties being subject to any agreements, consent orders, decrees or judgments currently in existence based on any Environmental Laws that negatively and materially impact the future use of any portion of the Oil and Gas Properties or that require any material change in the present conditions of any of the Oil and Gas Properties; or (iii) the Oil and Gas Properties being subject to any material uncured violations of or non-compliance with any applicable Environmental Laws or any Lease or agreement. Buyer shall be deemed to have conclusively waived (i) all Adverse Environmental Conditions not contained in an Environmental Defect Notice delivered to Seller on or before the Defect Notice Deadline, and (ii) any remedy against Seller for Adverse Environmental Conditions if the Environmental Defect Value of all Adverse Environmental Conditions do not exceed the Environmental Defect Threshold.

6.4 Rights and Remedies for Adverse Environmental Conditions.

(A) With respect to any Adverse Environmental Conditions affecting one or more of the Oil and Gas Properties which exceed the Environmental Defect Threshold, Seller may on an property-by-property basis (i) cause Company at Seller’s expense to remediate the Adverse Environmental Conditions to Buyer’s reasonable satisfaction prior to Closing, but Seller shall have no obligation to do so, and proceed to Closing with no adjustment of the Base Purchase Price; (ii) proceed to Closing and adjust the Base Purchase Price in an amount equal to the applicable Environmental Defect Value; or (iii) deem the affected Oil and Gas Property an Excluded Asset and reduce the Base Purchase Price by the Allocated Value of the affected Oil and Gas Property (“Exclusion Adjustment”).

(B) Buyer waives any Adverse Environmental Condition for which Buyer has received an adjustment to the Base Purchase Price in accordance with Section 6.4(A).

(C) If Buyer delivers a valid Environmental Defect Notice to Seller and if the aggregate of the Environmental Defects claimed is less than the Environmental Defect Threshold, Buyer will be deemed to have accepted the Oil and Gas Properties “where-is, as-is” with

respect to all Adverse Environmental Conditions in, on or under the Oil and Gas Properties. The Environmental Defect Threshold is a threshold and not a deductible. The Environmental Defect Threshold and the Title Defect Threshold are separate and distinct and operate independently.

(D) If the aggregate value of (i) the Base Purchase Price adjustment for Adverse Environmental Conditions plus (ii) any Exclusion Adjustments in lieu of Remediating any Adverse Environmental Conditions equals or exceeds ten percent (10%) of the Base Purchase Price, either Party may terminate this Agreement and neither Party shall have any further obligation to conclude the transfer of the Oil and Gas Properties under this Agreement.

(E) The term “Remediate” or “Remediation” means, with respect to any valid Adverse Environmental Condition, causing the Company at Seller’s expense to undertake and complete those actions and activities necessary to eliminate or correct such Adverse Environmental Condition to the degree sufficient that such Adverse Environmental Condition no longer constitutes an Adverse Environmental Condition as defined above. Seller shall promptly notify Buyer at such time as it believes that it has Remediated an Adverse Environmental Condition. Buyer shall promptly notify Seller whether it agrees such condition is Remediated. If Buyer fails to notify Seller of its determination with respect to such Remediation within ten (10) business days following Seller’s notice, such Adverse Environmental Condition shall be deemed Remediated.

(F) �� If Seller and Buyer are unable to agree on the amount of the Environmental Defect Value within ten (10) business days after Seller’s receipt of the Environmental Defect Notice or that an Adverse Environmental Condition exists, has been Remediated or is required to be Remediated, then the dispute will be submitted to a mutually acceptable company with recognized expertise in the oil and gas environmental remediation and regulation field (the “Environmental Consultant”) whose determination shall be final and binding upon the Parties. Seller and Buyer shall each bear their respective costs and expenses incurred in connection with any such dispute, and one-half (1/2) of the fees, costs and expenses charged by the Environmental Consultant. Each Party shall present a written statement of its position on the Adverse Environmental Condition and/or the Environmental Defect Value in question to the Environmental Consultant within five (5) business days after the Environmental Consultant is selected, and the Environmental Consultant shall make a determination of all points of disagreement in accordance with the terms and conditions of this Agreement within ten (10) business days of receipt of such position statements. If necessary, the Closing Date shall be deferred until the Environmental Consultant has made a determination of the disputed issues with respect thereto; provided, however, that, unless Seller and Buyer mutually agree to the contrary, the Closing Date shall not be deferred in any event for more than thirty (30) days beyond the scheduled Closing Date in Section 3.1. Once the Environmental Consultant’s determination has been expressed to both Parties, if applicable, Seller shall have five (5) business days in which to advise Buyer in writing which of the options available to Seller under Section 6.4(A) Seller elects regarding each of the Oil and Gas Properties as to which the Environmental Consultant has made a determination.

6.5 Remediation by Seller. If Seller elects to Remediate an Adverse Environmental Condition or is required by a governmental or regulatory agency to Remediate an Adverse Environmental Condition, the following will govern the Remediation:

(A) Seller shall be responsible for all negotiations and contacts with federal, state, and local agencies and authorities.

Seller agrees to make available to Buyer prior to and for a period of twelve (12) months following Closing any and all existing information and documents in the possession of Seller that Buyer may reasonably require to comply with Buyer’s tax and financial reporting requirements and audits.

Seller’s cooperation will include (i) such reasonable access to Seller’s employees who were responsible for preparing the financialstatements and work papers and other supporting documents used in the preparation of such financial statements as may be required by Buyer’s Auditor to perform an audit in accordance with generally accepted auditing standards, and (ii) delivery of one or more customary representation letters (in substantially the form previously approved by Seller and Buyer) from Seller to Buyer’s Auditor that are requested by Buyer to allow such auditors to complete an audit (or review of any interim quarterly

financials), and to issue an opinion that in Buyer’s experience is acceptable with respect to an audit or review of those financialstatements required pursuant to this Section. Buyer will reimburse Seller, within three (3) business days after demand therefor, for any reasonable out-of-pocket and overhead costs with respect to any costs incurred by Seller in complying with the provisions of this Section.

(B) Notification. The Seller and the Company shall give prompt notice to Buyer, and Buyer shall give prompt notice to the Seller and the Company, of (i) any representation or warranty made by it contained in this Agreement becoming untrue or inaccurate in any material respect or (ii) the failure by it to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations or warranties or covenants or agreements of the parties or the conditions to the obligations of the parties hereunder.

9.5 Payment of Indebtedness. Seller will cause all indebtedness owed to the Company by Seller or any Affiliate of Seller, if any, to be paid in full prior to Closing.

9.6 Insider Debt and Liabilities. All debt, obligations and liabilities, if any, owed by the Company to Seller and its Affiliates shall be deemed paid and cancelled at Closing. Seller

agrees to and agrees to cause its Affiliates to waive and release the Company, from any and all such debts, liabilities and obligations, by executing and delivering a release at Closing in a form acceptable to Buyer (collectively, the “Releases”). Seller shall deliver any documents evidencing such debt, if any, marked paid, to Buyer at Closing.

9.7 Operation of Oil and Gas Properties. Seller shall cause the transfer all operations of the Oil and Gas Properties to Buyer or Buyer’s designee effective as of Closing.

10. CERTAIN AGREEMENTS OF BUYER. Buyer agrees and covenants that unless Seller shall have consented otherwise in writing, the following provisions shall apply:

Upon consummation of the Closing, the Company and Buyer shall perform all necessary and proper plugging and abandonment of all Wells and all surface restoration and reclamation required by law or the Leases, in each case to the extent the same relate to the Oil and Gas Properties.

10.2 Plugging Bond. The Company, Buyer or Buyer’s Affiliate shall post, prior to Closing, the necessary bonds or letters of credit as required by the state in which the Leases are located for the plugging of all Wells, and provide Seller with a copy of same, and provide proof satisfactory to Seller that the applicable state has accepted such bonds or letters of credit as sufficient assurance to cover the plugging of all Wells and related matters. Further, Buyer shall provide to Seller copies of the approval by any applicable regulatory agencies concerning change of operatorship of the Oil and Gas Properties if Buyer or Buyer’s Affiliate is duly elected Operator.

10.3 Seller’s Logos. Commencing no later than sixty (60) days after Closing, Buyer shall promptly cover or cause to be covered by decals or new signage any names and marks on the Oil and Gas Properties used by Seller, and all variations and derivatives thereof and logos relating thereto, and shall not thereafter make any use whatsoever of such names, marks and logos.

10.4 Like-Kind Exchanges. Each Party consents to the other Party’s assignment of its rights and obligations under this Agreement to its Qualified Intermediary (as that term is defined in Section 1.1031(k)-1(g)(4)(v) of the Treasury Regulations), or to its Qualified Exchange Accommodation Titleholder (as that term is defined in Rev. Proc. 2000-37), in connection with effectuation of a like-kind exchange. However, Seller and Buyer acknowledge and agree that any assignment of this Agreement to a Qualified Intermediary or to a Qualified Exchange Accommodation Titleholder does not release either Party from any of their respective liabilities and obligations to each other under the Agreement. Each Party agrees to cooperate with the other to attempt to structure the transaction as a like-kind exchange. The electing Party shall indemnify and hold harmless the non-electing Party from and against all claims, expenses (including reasonable attorney’s fees and court costs) and liabilities resulting from any such like-kind exchange.

13.2 Effect of Termination.

If Closing does not occur because Buyer wrongfully fails to tender performance at Closing or otherwise breaches this Agreement prior to Closing, and Seller is ready to close and is not in material breach of this Agreement, Seller shall have the right to terminate this Agreement and retain the Deposit, together with interest thereon, as liquidated damages. Buyer’s failure to close shall not be considered wrongful if (i) conditions to Buyer’s obligation to close under Article 11 are not satisfied through no fault of Buyer and are not waived, or (ii) Buyer has terminated this Agreement as of right under Section 13.1. The remedy set forth herein shall be Seller’s sole and exclusive remedy for Buyer’s wrongful failure to close hereunder and Seller expressly waives any and all other remedies, legal and equitable, that it otherwise may have for Buyer’s failure to close.

(B) Seller’s Breach. If Closing does not occur because Seller wrongfully fails to tender performance at Closing or otherwise breaches this Agreement prior to Closing, and Buyer is ready to close and is not in material breach of this Agreement, Buyer may terminate this Agreement, in which event Seller will return the Deposit, together with interest thereon, to Buyer immediately after the determination that the Closing will not occur. If Buyer elects not to terminate this Agreement upon any such breach by Seller, Buyer shall retain all legal remedies for Seller’s breach of this Agreement, including, without limitation, specific performance of this Agreement. Seller’s failure to close shall not be considered wrongful if (i) conditions to Seller’s conditions to close under Article 12 are not satisfied through no fault of Seller and are not waived; or (ii) Seller has terminated this Agreement as of right under Section 13.1.

(C) Termination Pursuant to Section 13.1. If Buyer or Seller terminates this Agreement pursuant to Section 13.1 in the absence of a breach by the other Party, Seller shall return the Deposit and all accrued interest thereon to Buyer and neither Buyer nor Seller shall have any liability to the other Party for termination of this Agreement. If Buyer or Seller terminates this Agreement pursuant to Section 13.1 and asserts that a breach of this Agreement has occurred, the notice of termination shall include a statement describing the nature of the alleged breach together with supporting documentation.

(D) Effect of Termination. In the event of the termination of this Agreement pursuant to the provisions of this Article 13 or elsewhere in this Agreement, this Agreement shall become void and have no further force and effect and, except as provided in this Article 13, for the indemnities provided for in Sections 6.2(B) and 14.3, any breach of this Agreement prior to such termination and any continuing confidentiality requirement, neither Party shall have any further right, duty or liability to the other hereunder. Upon termination, Buyer agrees to return to Seller or destroy all materials, documents and copies thereof provided, obtained or discovered in the course of any due diligence investigations of the Assets.

14.4 Notification.

The foregoing shall not effect or limit any liability or indemnification related to any breach of representation, warranty or covenant of Seller or the Company set forth herein.

(B) Seller shall cause to be prepared (subject to Buyer’s review and approval) any and all tax returns which are required to be filed for, by, on behalf of, or with respect to, the Company for any period before June 30, 2008, including any tax return required for any short tax year ending as of the Effective Time.

(D) In connection with the preparation of any tax return or with respect to any Tax Contest, each of the parties hereto shall grant or cause to be granted to the other parties or such parties’ representatives, access at all reasonable times during normal business hours and following reasonable notice to all information, books and records relating to the Company within its possession or control, including the right to make copies thereof to the extent reasonably necessary in connection with the rights and responsibilities for the tax matters set forth herein, and shall furnish such assistance and cooperation as may be reasonably requested in connection therewith.

16. MISCELLANEOUS.

16.1 Casualty Loss.

(A) An event of casualty means volcanic eruptions, acts of God, fire, explosion, earthquake, wind storm, flood, drought, condemnation, the exercise of any right of eminent domain, confiscation and seizure (a “Casualty”). A Casualty does not include depletion due to normal production and depreciation or failure of equipment or casing.

(B) If, prior to the Closing, a Casualty occurs (or Casualties occur) which results in a reduction in the value of any of the Oil and Gas Properties (“Casualty Loss”), (i) Seller shall retain such Oil and Gas Property and such Oil and Gas Property shall be the subject of an adjustment to the Base Purchase Price in the same manner set forth in Section 5.4 hereof, or (ii) at the Closing, Seller shall assign to Buyer or the Company, at Buyer’s election, the right to receive all insurance proceeds or other sums payable to Seller or its Affiliates by reason of such Casualty Loss, the Base Purchase Price shall not be adjusted by reason of such payment, and the affected Oil and Gas Property will continue to be owned by the Company. In the event a Casualty Loss results in a five percent (5%) or greater reduction in the value of an affected Oil and Gas Property, Buyer shall have the right to exclude such Oil and Gas Property from this transaction, receive a reduction of the Base Purchase Price based on the Allocated Value of such Oil and Gas Property, and the Company shall transfer the affected Oil and Gas Property to Seller or Seller’s designee as an Excluded Asset.

(C) For purposes of determining the diminution in value of an Asset as a result of a Casualty Loss, the Parties shall use the same methodology as applied in determining the diminution in value of an Asset as a result of a Title Defect as set forth in Section 5.4.

16.2 Confidentiality.

(A) Prior to Closing, to the extent not already public, Buyer shall not disclose to any party that it is conducting negotiations with Seller or has entered into this Agreement other than as expressly provided herein or as permitted in the confidentiality agreement executed by Buyer in Seller’s favor prior to the execution of this Agreement, which shall continue to apply until the Closing and thereafter in the event of termination of this Agreement prior to the Closing. Buyer shall exercise all due diligence in safeguarding and maintaining secure all engineering, geological and geophysical data, seismic data, reports and maps, the results and findings of Buyer with regard to its due diligence associated with the Assets (including without limitation with regard to due diligence associated with environmental and title matters) and other data relating to the Assets (collectively, the “Confidential Information”). Buyer acknowledges that, prior to Closing, all Confidential Information shall be treated as confidential. Notwithstanding the foregoing, Seller understands that Buyer has public reporting obligations that may require public announcement of certain information relating to this Agreement. Seller and Buyer shall consult with each other with regard to all publicity and other releases at or prior to the Closing concerning this Agreement and the transaction contemplated hereby and, except as provided herein or as required by applicable law or other applicable rules or regulations of any governmental body or stock exchange, neither party shall issue any publicity or other release without the prior written consent of the other party, such consent not to be unreasonably withheld.

(B) In the event of termination of this Agreement for any reason, Buyer shall not use or knowingly permit others to use such Confidential Information in a manner detrimental to Seller, and will not disclose any such Confidential Information to any person, firm, corporation, association or other entity for any reason or purpose whatsoever, except to Seller or to a governmental agency pursuant to a valid subpoena or other order or pursuant to applicable governmental regulations, rules or statutes.

(C) The undertaking of confidentiality shall not diminish or take precedence over any separate confidentiality agreement between the Parties. Should this Agreement terminate, such separate confidentiality agreement shall remain in full force and effect.
