NOW, THEREFORE, for and in consideration of the mutual covenants and agreements herein contained, the parties to this Amendment hereby agree as follows:

Section 3. Redetermination of the Borrowing Base.

(a) As of the Amendment Effective Date, the amount of the Borrowing Base under the Credit Agreement shall be increased to $475,000,000, which Borrowing Base shall remain in effect until (i) reduced pursuant to clause (b) of this Section 3 (if applicable) or (ii) redetermined or adjusted, as applicable, in accordance with the provisions of Section 2.04 of the Credit Agreement or otherwise.

(b) If (i) a Pending Disposition shall have occurred within 120 days following the Amendment Effective Date, the Borrowing Base then in effect shall automatically be reduced by $37,500,000, effective upon the consummation of the first Pending Disposition to occur (if any) after the Amendment Effective Date, and (ii) a second Pending Disposition shall have occurred within 120 days following the Amendment Effective Date the Borrowing Base (as reduced by the foregoing subclause (i) and as otherwise then in effect) shall automatically be further reduced by an additional $37,500,000, effective upon the consummation of the second Pending Disposition to occur (if any) after the Amendment Effective Date. The Borrowing Base, as so reduced pursuant to this clause (b), shall remain in effect until further redetermined or adjusted in accordance with the provisions of Section 2.04 of the Credit Agreement or otherwise.

(c) Both the Borrower, on the one hand, and the Administrative Agent and the Lenders, on the other hand, agree that the redetermination of the Borrowing Base pursuant to the foregoing clause (a) of this Section 3 shall constitute the regularly scheduled redetermination of the Borrowing Base for Spring 2014, and the redetermination of the Borrowing Base pursuant to the foregoing clause (b) of this Section 3 shall constitute the adjustment contemplated by Section 6.13 of the Credit Agreement (and neither the redetermination pursuant to clause (a) nor any automatic reduction pursuant to clause (b) shall constitute a discretionary redetermination of the Borrowing Base by either the Borrower, on the one hand, or the Administrative Agent or the Lenders, on the other hand, pursuant to Section 2.04(e) of the Credit Agreement).

(d) For the avoidance of doubt, in the event that a Borrowing Base Deficiency exists after giving effect to a reduction in the Borrowing Base pursuant to the foregoing clause (b) of this Section 3, the Borrower covenants and agrees to use the Net Cash Proceeds of the applicable Pending Disposition to eliminate such Borrowing Base Deficiency in accordance with Section 2.11(a)(ii) of the Credit Agreement.
