“Borrower will, and will cause each Subsidiary to, use the proceeds of the Loans for Borrower’s and its Subsidiaries’ general corporate purposes in the ordinary course of business, including without limitation for working capital, non-hostile acquisitions and development of Oil and Gas Properties; provided, however, that proceeds of Loans shall not be used to redeem, purchase, repay, terminate or otherwise defease or cancel any Senior Notes in an amount in excess of the amount of cash proceeds from any sale of Property permitted by Section 7.5(g) actually utilized to repay Loans.”

D.                                    Section 6.1 of the Credit Agreement hereby is amended in its entirety to read as follows:

III.                              Effectiveness.  This Amendment shall become effective as of September 12, 2013 (the “First Amendment Effective Date”) when the Administrative Agent shall have received counterparts hereof duly executed by the Borrower, the Administrative Agent and the Borrowing Base Required Lenders (or, in the case of any party as to which an executed counterpart shall not

C.                                    The execution, delivery and performance by the Borrower of this Amendment are within the Borrower’s corporate powers, and have been duly authorized by all necessary corporate action.  This Amendment has been duly executed and delivered by the Borrower and, when duly executed and delivered by the other parties hereto, will constitute, a legal, valid and binding obligation of the Borrower, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

D.                                    The execution, delivery and performance by the Borrower of this Amendment (i) do not require any Governmental Approval or third party approvals, except such as have been obtained or made and are in full force and effect, (ii) will not violate any applicable Governmental Rule or the Organic Documents of the Borrower or any order of any Governmental Authority, (iii) will not violate or result in a default under any indenture, agreement or other instrument binding upon the Borrower or of its assets, or give rise to a right thereunder to require any payment to be made by the Borrower, and (iv) will not result in the creation or imposition of any Lien on any asset of the Borrower (other than Liens created under the Loan Documents).

E.                                     No Default under the Loan Documents has occurred and is continuing and the Borrower is in compliance with the financial covenant set forth in Article VI of the Credit Agreement (as amended by this Amendment).

F.                                      No event or events have occurred which individually or in the aggregate could reasonably be expected to have a Material Adverse Effect.

VI.                               Reaffirmation of Credit Agreement.  This Amendment shall be deemed to be an amendment to the Credit Agreement, and the Credit Agreement, as amended hereby, is hereby ratified, approved and confirmed in each and every respect.  All references to the Credit Agreement herein and in any other document, instrument, agreement or writing shall hereafter be deemed to refer to the Credit Agreement as amended hereby.

VII.                          Governing Law.  THIS AMENDMENT SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

VIII.                     Severability of Provisions. Any provision of this Amendment held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

IX.                              Counterparts. This Amendment may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract.  Delivery of an executed counterpart of a signature page of this Amendment by telecopy shall be effective as delivery of a manually executed counterpart of this Amendment.
