On September 11, 2013, Sanchez Energy Corporation (the “Company”) and its subsidiaries, SEP Holdings III, LLC, SN Marquis LLC, and SN Cotulla Assets, LLC, as Borrowers, and Royal Bank of Canada, as Administrative Agent, and the other Lenders party thereto entered into an amendment (the “Amendment”) to the Company’s Amended and Restated Credit Agreement, dated as of May 31, 2013 (the “Credit Agreement”), to (i) increase the aggregate principal amount of senior unsecured notes that the Company may issue from time to time in private placement transactions from the current $400 million limit to $600 million, (ii) make some technical modifications to the automatic borrowing base reduction calculation provision in connection with debt issuances and incurrences (the “Automatic Borrowing Base Reduction Provision”), such that the reduction is 25% of the net increase in the principal amount of certain debt rather than 25% of the net proceeds received in connection with the issuance or incurrence of such debt, (iii) waive the borrowing base reduction that would result from the Automatic Borrowing Base Reduction Provision in connection with the issuance of senior unsecured notes after September 1, 2013 and before the earlier of (a) January 1, 2014 and (b) the effective date of the borrowing base redetermined in connection with the scheduled quarterly redetermination of the borrowing base for the fourth quarter of 2013, and (iv) permit the Company to hedge incremental proved reserves following the closing of the Company’s recently announced Wycross acquisition as if such incremental proved reserves had been included in the then most recently delivered reserve report at the time of such acquisition.

From time to time, the Administrative Agents and the Lenders party to the Amendment have provided, or may in the future provide, various investment banking, commercial banking, financial advisory, brokerage and other services to the Company and its affiliates for which services they have received, and may in the future receive, customary fees and expense reimbursement.
