     4.2 Conduct of Business Prior to Closing. Seller covenants and agrees that prior to Closing:

     (a) Negative Covenants. During the Interim Period, Seller shall not, except with the prior written consent of Buyer, which shall not be unreasonably withheld, conditioned or delayed:

          (i) sell, lease, dispose of or abandon any of the Assets, or allow any of the Assets to be subjected to any mortgage, pledge, lien, security interest or encumbrance of any kind which is not in existence as of the date hereof;

          (ii) elect not to participate (i.e., go “non-consent”) in any new Well, recompletion, rework, sidetrack or other Well operation proposed under applicable joint operating agreements or other Contracts with respect to the Properties or any of them.

     (b) Affirmative Covenants. Seller shall, throughout the Interim Period, cause the Assets to be owned, produced, maintained and (where applicable) operated in the ordinary course of business consistent with good industry practices. Seller shall promptly give Buyer notice of (i) any legal actions which to Seller’s knowledge have been initiated or threatened, by or against Seller whether by a Governmental Entity or other Person, and which relate to the Assets or the ability of Seller to proceed to Closing, (ii) to the extent material, any notice or other communication received by Seller, whether from a Governmental Entity or otherwise, in respect of any Asset or in connection with the transactions contemplated by this Agreement, including any notice from a person alleging that the consent of such person is or may be required in connection therewith, and (iii) the material damage or destruction of any part of the Assets.

     4.3 Imbalances, Prepayments and Refunds. The parties recognize that as of the Effective Date there may be (i) wellhead gas imbalances (“Imbalances”) with respect to production from or attributable to certain of the Properties, whether such Imbalances be instances of overproduction (“Imbalance Obligations”) or underproduction (“Imbalance Entitlements”), (ii) prepayment obligations due to monies received by Seller under production sales contracts or similar agreements containing “take-or-pay” clauses (or similar arrangements), whereby Seller is obligated to deliver oil or gas produced after the Effective Date with respect to a Property without receiving payment therefor in the ordinary course of business (“Prepayment Obligations”), or (iii) refund obligations arising from Seller’s sale of oil or gas produced from a Property prior to the Effective Date at prices exceeding the applicable maximum lawful prices (“Refund Obligations”). The parties agree that, from and after the date of this Agreement, they shall jointly attempt to ascertain prior to Closing all Imbalances, Prepayment Obligations and Refund Obligations affecting the Properties as of the Effective Date. The parties agree that they shall adjust the Purchase Price at Closing for all discovered Imbalances, Prepayment Obligations and Refund Obligations in accordance with the following procedures:

     (a) Imbalances. The value of discovered Imbalances allocable to the Properties existing as of the Effective Date shall be calculated by multiplying the overproduced or underproduced volumes by $4.00 per MMBtu, net of all royalty and severance tax burdens. At Closing or on the Final Settlement Date, as the case may be, the Purchase Price shall be adjusted upward for the aggregate value of all Imbalance Entitlements and downward for the aggregate value of all Imbalance Obligations, in each cost allocable to the Properties. As to Imbalances allocable to the Properties discovered after the Final Settlement Date, Buyer shall bear all obligations with respect to any overproduction liability and shall receive the benefit of and be credited with any underproduction credit, including overproduction and

underproduction attributable to periods of time prior to the Effective Date. If the Imbalance Obligation exceeds the Allocated Value of a Property, Seller may remove such Property from the Assets to be sold to Buyer and the Base Purchase Price shall be reduced by the Allocated Value of such Property. Buyer shall not assume any obligation of Seller with respect to pipeline gas imbalances as of the Effective Date that may be associated with the Properties. Any such pipeline gas imbalance shall remain with and continue as the sole responsibility of the Seller.

     (b) Prepayment Obligations. At Closing, the Purchase Price shall be adjusted downward by all amounts received by Seller prior to the Effective Date with respect to Prepayment Obligations allocable to the Properties. All amounts received by Seller after the Effective Date and prior to the Final Settlement Date due to Prepayment Obligations allocable to the Properties shall be credited to Buyer.

     (c) Refund Obligations. At Closing, the Purchase Price shall be adjusted downward by all amounts received by Seller prior to the Effective Date with respect to Refund Obligations allocable to the Properties. With respect to Refund Obligations allocable to the Properties not discovered by Closing, Seller will be liable for such Refund Obligations allocable to the Properties for a period expiring two (2) year after the Closing Date.

     4.4 TAG Team Preferential Right to Purchase. Seller shall seek to acquire from TAG Team a preferential right to purchase the TAG Team Properties (“TAG Team Preferential Right”). The TAG Team Preferential Right shall contain substantially the same language as that set forth in Exhibit F attached hereto and contain no conditions as to its assignment to Buyer. Seller shall unconditionally assign the TAG Team Preferential Right to Buyer at Closing.

     4.5 Audited Financials. After the date of this Agreement, Seller agrees to cooperate with and provide reasonable assistance to Buyer in the construction of audited financial statements respecting the Assets for the prior three fiscal years, at Buyer’s sole expense.

ARTICLE V
TITLE MATTERS AND CASUALTY LOSSES

     5.1 Title and Environmental Investigation. Buyer may conduct, at its cost, such title and environmental examination and investigation, and other examinations and investigations, as it may in its discretion choose to conduct with respect to the Assets in order to determine whether any Title Defects or Environmental Defects exist.

     5.2 Notice of Title Defects. Buyer shall give Seller written “Notice of Title Defects” as soon as possible but no later than 5:00 p.m., Central Time, on the Defect Date, provided that Buyer shall notify Seller of possible Title Defects as soon as reasonably practicable after Buyer becomes aware of the same. Such notice shall be in writing and inclusion of the following elements shall be a condition precedent to the effectiveness of the Notice of Title Defects: (i) a description of the Title Defect, (ii) the reasonable basis for the Title Defect, including reasonable documentation supporting the basis for the Title Defect, if available, (ii) the Allocated Value of the affected Asset, and (iv) the

Defect Value and the computations upon which Buyer’s belief is based. If Buyer does not deliver a timely Notice of Title Defects for a particular Asset, title to such Asset shall be deemed to be Defensible Title.

     5.3 Title Defect Adjustments and Exclusions. . Subject to this Section 5.3 and Section 5.7 respecting the Defect Threshold, if any Asset is affected by a Title Defect, the Base Purchase Price shall be reduced in accordance with Section 2.2(b)(iv) by the Defect Value (which reduction shall be called a “Defect Adjustment”) unless, (i) Buyer agrees in writing to waive the relevant Title Defect, (ii) the basis for treating such Asset as subject to a Title Defect has been removed by Seller at his sole cost and expense prior to the Closing Date, or (iii) Seller and Buyer reach a subsequent agreement regarding curative of the Title Defect prior to Closing. The Base Purchase Price shall be adjusted only if the Defect Threshold, i.e., the Defect Value respecting each individual Property is equal to or exceeds $10,000 and the aggregate Defect Value of all Title Defects and Environmental Defects exceeds $200,000, in which event, the Base Purchase Price shall be reduced by the amount of the total Defect Values (i.e., which amount is a threshold, not a deductible).

     5.4 Title Defect Value. In determining which portions of an Asset constitute a Title Defect, it is the intent of the parties to include, to the extent possible, only that portion of any affected Asset (whether a Well, unit or leasehold interest, as applicable) that is adversely affected by the defect. The Defect Value for a Title Defect shall not exceed the Allocated Value of the Asset and shall be determined by the parties in good faith taking into account all relevant factors, including, but not limited to, the following:

     (a) The Allocated Value of the affected Asset;

     (b) The potential or actual reduction in the warranted NRI of the affected Property, or the potential or actual increase in the warranted WI to the extent such increase is not accompanied by a corresponding increase in NRI;

     (c) If the Title Defect represents only a possibility of title failure, the probability that such failure will occur;

     (d) The legal effect of the Title Defect; and

     (e) If the Title Defect is a lien or encumbrance on an Asset, the cost of removing such lien or encumbrance.

     5.5 Title Increases. To the extent that same are discovered by Buyer prior to the Defect Date, Seller and Buyer acknowledge and agree that the Base Purchase Price shall be increased (a “Title Increase”) by an amount determined as follows:

     (a) any increase in Seller’s NRI above that NRI shown on Exhibit A for any Property without a corresponding increase in Seller’s WI above that WI shown on Exhibit A for such Property; or

     (b) any decrease in Seller’s WI below that shown on Exhibit A for any Property without a corresponding decrease in Seller’s NRI shown on Exhibit A for such Property, in each case with such values to be agreed upon by Seller and Buyer (taking into account the Allocated Value for such Property).

Title Increases shall be available to Seller only to the extent Buyer has asserted Title Defects and may be applied to set off decreases in the Base Purchase only after the total of Defects has exceeded the Defect Threshold. The intent is that there can be no net upward adjustment to the Base Purchase Price based upon Title Increases and that such increases are only available to Seller as a set off against reductions in the Purchase Price because of Title Defects.

     5.6 Casualty Loss. If, prior to Closing, a portion of an Asset is destroyed by fire or other casualty, is taken or threatened to be taken in condemnation or under the right of eminent domain (a “Casualty Loss”), the Asset shall be included in the sale for the Allocated Value of the affected Asset, reduced by the mutually agreed cost to repair such affected Asset (with equipment of similar utility) up to the Allocated Value thereof (the reduction being the “Net Casualty Loss”) and Seller shall retain all rights to any insurance payments, awards or other payments from third parties arising out of the Casualty Loss. Any dispute concerning the amount of a Net Casualty Loss shall be resolved through arbitration pursuant to Section 9.11 except the Arbitrator to be selected shall have a minimum of fifteen (15) years’ experience in oil and gas insurance matters rather than in oil and gas accounting.

     5.7 Environmental Defects. If (i) Buyer notifies Seller on or before the Defect Date of the existence of any environmental conditions on or underlying the Assets, or any portion thereof, that (A) constitutes a violation of Environmental Laws, or (B) poses a material risk of injury to human health or the environment, and (ii) the aggregate remediation costs of all such Environmental Defects for Properties when combined with all asserted Title Defects, exceeds the Defect Threshold, then the following shall occur:

     (a) Seller shall have the right to remediate any and all Environmental Defects on or before the Closing, provided such remediation can be completed to Buyer’s reasonable satisfaction; or

     (b) Buyer and Seller shall reach agreement upon an appropriate reduction to the Base Purchase Price which shall be based, in large part, upon the anticipated remediation costs for each such Environmental Defect; or

     (c) In the event Seller is unable to cure or otherwise remediate an Environmental Defect prior to Closing and the parties are unable to reach agreement on an appropriate reduction to the Base Purchase Price, the Asset affected by such Environmental Defect shall be removed from the sale and the Base Purchase Price shall be reduced by the Allocated Value therefor.

     5.8 Environmental Laws. As used herein, the term “Environmental Law” shall mean any and all laws, statutes, regulations, rules, orders, ordinances, permits, or determinations of any governmental authority pertaining to health or the environment in effect in any and all jurisdictions

in which the Assets are located, including, without limitation, the Clean Air Act, as amended, the Federal Water Pollution Control Act, as amended, the River and Harbor Act, as amended, the Safe Drinking Water Act, as amended, the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), as amended, the Superfund Amendments and Reauthorization Act of 1986, as amended, the Resource Conservation and Recovery Act (RCRA), as amended, the Hazardous and Solid Waste Amendments Act of 1984, as amended, the Toxic Substances Control Act, as amended, the Occupational Safety and Health Act, as amended, and other federal, state, and local laws whose purpose is to conserve or protect health, the environment, wildlife, or natural resources. The terms hazardous substances, release, and threatened release shall have the meanings specified in CERCLA; provided, however, that (i) to the extent the laws of the state in which the Assets are located are applicable and have established a meaning for hazardous substances, release, threatened release, solid waste, hazardous waste, and disposal that is broader than that specified in CERCLA or RCRA, such broader meaning shall apply with respect to the matters covered by such laws, and (ii) the term solid waste shall include all oil and gas exploration, development and production wastes, even if such wastes are specifically exempt from classification as hazardous substances or hazardous wastes pursuant to CERCLA or RCRA, or the state analogues to those statutes.

     5.9 Mutual Right to Terminate. Notwithstanding anything contained herein to the contrary, either Seller or Buyer may terminate this Agreement, in their sole and absolute discretion, if the sum of all Defect Adjustments (less offsets for Title Increases), casualty losses, and anticipated remediation costs for Environmental Defects exceed ten percent (10%) of the Base Purchase Price. If, in such event, either Seller or Buyer elects to terminate this Agreement, this Agreement shall terminate and be of no further force or effect.
