Section 2.1.                                  Purchase Price .  In consideration of the sale of the Properties by Sellers to Buyer, Buyer shall pay to Sellers cash in the amount of FIVE HUNDRED NINETY-NINE

Section 2.2.                                  Accounting Adjustments .

(a)           Subject to Section 2.2(b) , and in addition to other adjustments to the Purchase Price provided for in this Agreement, appropriate adjustments shall be made between Buyer and Sellers so that:

(i)           all expenses (including all drilling costs, all capital expenditures, and all overhead administrative charges under applicable operating agreements, and all other operating costs actually charged by third parties) for work done in the operation of the Properties on or after the Effective Date will be borne by Buyer, and all proceeds (net of applicable gathering, transportation charges as well as production, severance, and similar Taxes) from the sale of oil, gas or other minerals produced from the Oil and Gas Properties on or after the Effective Date will be received by Buyer, and

(ii)           all expenses for work done in the operation of the Properties before the Effective Date will be borne by Sellers and all proceeds (net of applicable production, severance, and similar Taxes) from the sale of oil, gas, or other minerals produced therefrom before the Effective Date will be received by Sellers.

(b)           It is agreed that, in making the adjustments contemplated by Section 2.2(a) :

(i)           Oil which was produced from the Oil and Gas Properties and which was, on the Effective Date, stored in tanks, but without taking into account tank bottom sediment and water,  located on the Oil and Gas Properties (or located elsewhere but used to store oil produced from the Oil and Gas Properties prior to delivery to oil purchasers) and above pipeline connections shall be deemed to have been produced before the Effective Date (it is recognized that such tanks were not gauged on the Effective Date for the purposes of this Agreement and that determination of the volume of such oil in storage will be based on the best available data, which may include estimates),

(ii)           ad valorem Taxes assessed with respect to a period which begins before and ends on or after the Effective Date shall be prorated based on the number of days in such period which fall on each side of the Effective Date (with the day on which the Effective Date falls being counted in the period after the Effective Date), and

Section 2.3.                                  Closing and Post-Closing Accounting Settlements .

(a)           No later than three (3) business days prior to the Closing Date, the parties shall determine, based upon the best information reasonably available to them, the amount of the

adjustments provided for in Section 2.2 .   If the amount of adjustments so determined which would result in a credit to Buyer exceed the amount of adjustments so determined which would result in a credit to Sellers, Buyer shall receive a credit, for the amount of such excess, against the Purchase Price to be paid at Closing, and, if the converse is true, Buyer shall pay to Sellers, at Closing (in addition to amounts otherwise then owed), the amount of such excess.

(b)           On or before 120 days after Closing, Buyer and Sellers shall review any additional information which may then be available pertaining to the adjustments provided for in Section 2.2 , shall determine if any additional adjustments (whether the same be made to account for expenses or revenues not considered in making the adjustments made at Closing, or to correct errors made in such adjustments) should be made beyond those made at Closing, and shall make any such adjustments by appropriate payments from Sellers to Buyer or from Buyer to Sellers.   Following such additional adjustments, no further adjustments to the Purchase Price shall be made under this Section 2.3 .

(c)           If a dispute arises under Section 2.3(b) with respect to any additional adjustments (an “ Accounting Dispute ”) that the parties have been unable to resolve prior to the end of the 120 day period in Section 2.3(b) above, then, at the written request of either Sellers or Buyer (the “ Request Date ”), each of Sellers and Buyer shall nominate and commit one of their senior officers to meet at a mutually agreed time and place not later than ten days after the Request Date to attempt to resolve same.  If such senior officers have been unable to resolve such Accounting Dispute within a period of 30 days after the Request Date, any party shall have the right, by written notice to the other specifying in reasonable detail the basis for the Accounting Dispute, to resolve the Accounting Dispute by submission thereof to a independent public accounting firm mutually agreeable to the parties, which firm shall serve as sole arbitrator (the “ Accounting Referee ”).  The scope of the Accounting Referee’s engagement shall be limited to the resolution of the items described in the notice of the Accounting Dispute given in accordance with the foregoing and the corresponding calculation of the adjustments pursuant to Section 2.2 .  The Accounting Referee shall be instructed by the parties to resolve the Accounting Dispute as soon as reasonably practicable in light of the circumstances but in no event in excess of 15 days following the submission of the Accounting Dispute to the Accounting Referee.  The decision and award of the Accounting Referee shall be binding upon the parties as an award under the Federal Arbitration Act and final and nonappealable to the maximum extent permitted by law, and judgment thereon may be entered in a court of competent jurisdiction and enforced by any party as a final judgment of such court.  The fees and expenses of the Accounting Referee shall be borne equally by Sellers and Buyer.

Section 2.4.                                  Payment of Adjusted Purchase Price .  The Adjusted Purchase Price shall be paid to Sellers as follows:

(a)           Within one Business Day after the execution and delivery of this Agreement, Buyer shall tender to Sellers cash equal to ten percent (10%) of the Purchase Price, which is FIFTY-NINE MILLION NINE HUNDRED SEVEN THOUSAND AND NO\100 DOLLARS ($59,970,000.00), as a deposit (such amount, together with all interest earned thereon, the “ Deposit ”).  The Deposit shall (i) be applied against the Adjusted Purchase Price owing by Buyer at the Closing pursuant to Section 2.4(b) , (ii) retained by Sellers pursuant to Section 10.2 or (iii) returned to Buyer pursuant to Section 10.2 , as applicable.

(b)           At the Closing, Buyer shall pay to Sellers cash equal to the Adjusted Purchase Price less the Deposit.

(c)           All cash payments by Buyer pursuant to this Section 2.4 shall be made in immediately available funds by confirmed wire transfer to a bank account or accounts designated by Sellers, as applicable.

Section 2.5.                                  Allocation of Purchase Price .

(a)           Buyer, using its reasonable business judgment, has allocated the Purchase Price among the Oil and Gas Properties as shown on the attached Exhibit C.

(b)           On or before the Closing Date, the Buyer and Sellers shall agree in writing as to the allocation of the Adjusted Purchase Price among the Properties under the methodology required by Section 1060 of the Code.  Such agreed allocation shall be set forth on Schedule 2.5 attached hereto.  The Buyer and Sellers shall report the transactions contemplated hereby on all Tax Returns, including, but not limited to Form 8594, in a manner consistent with such allocation.  If, contrary to the intent of the parties hereto as expressed in this Section 2.5 , any taxing authority makes or proposes an allocation different from the allocation determined under this Section 2.5 , Buyer and Sellers shall cooperate with each other in good faith to contest such taxing authority’s allocation (or proposed allocation), provided, however, that, after consultation with the party adversely affected by such allocation (or proposed allocation), the other party hereto may file such protective claims or Tax Returns as may be reasonably required to protect its interests.

(c)           sell, transfer, or abandon any portion of the Properties other than items of materials, supplies, machinery, equipment, improvements, or other personal property or fixtures forming a part of the Properties (and then only if the same is replaced with an item of substantially equal suitability, free of liens and security interests, which replacement item will then, for the purposes of this Agreement, become part of the Properties); or

unobtained waiver is a waiver of a preferential right to purchase, and if both Buyer and Sellers agree to this treatment of such matter (and agree upon an appropriate allocation of the Purchase Price), Sellers will tender (at the agreed allocated portion of the Purchase Price) the required interest in the Property affected by such unwaived preferential right to purchase to the holder, or holders, of such right who have elected not to waive such preferential right to purchase, and if, and to the extent that, such preferential right to purchase is exercised by such party or parties, such interest in such Property will be excluded from the transaction contemplated hereby and the Purchase Price will be reduced by the amount paid, or to be paid, by the party exercising such preferential right to purchase (and Sellers shall collect such amount from such purchaser).
