“(c) by Sellers, if Purchaser shall have failed to fulfill in any material respect any of its obligations under this Agreement; and such failure has not been cured within five (5) days after written notice thereof from Seller to Purchaser; provided that, any cure period shall not extend beyond the Termination Date and shall not extend the Termination Date;”

1.04. Amendment to Section 7.8(a). Effective as of the date hereof, Section 7.8(a) of the Agreement is and shall be deleted and replaced in its entirety with the following:

“(a) Subject to the provisions of Section 12.3, Sellers shall be responsible for all Taxes related to the Assets (including ad valorem, property, severance, Hydrocarbon production and similar Taxes based upon or measured by the ownership or operation of the Assets or the production of Hydrocarbons therefrom, which are addressed and apportioned as set forth in Section 1.4) attributable to any period of time prior to the Effective Time, and Purchaser shall be responsible for all such Taxes related to the Assets attributable to any period of time on and after the Effective Time. Notwithstanding the foregoing, Sellers shall handle payment to the appropriate Governmental Body of all Taxes with respect to the Assets which are required to be paid prior to Closing (and shall file all Tax Returns with respect to such Taxes). If requested by Purchaser, Sellers will assist Purchaser with preparation of all ad valorem and property Tax Returns for periods ending on or before the Closing Date (including any extensions requested), but which are required to be paid after the Closing Date. Purchaser shall file all Tax Returns covering Taxes treated as Property Costs that are required to be filed after the Closing Date unless

If any Taxes allocated to Purchaser pursuant to this Section 7.8 or Section 1.4 are actually paid by Sellers and not already accounted for in an adjustment to the Purchase Price pursuant to Section 2.2(d), then, after the Closing Date and upon written request by Sellers, Purchaser shall, within fifteen (15) Business Days of such request, make a payment to Sellers of the amount of any such Taxes paid by Sellers but allocated to Purchaser.”
