You have further advised SunTrust that, in connection with the Acquisition, the Company seeks to amend its existing senior credit facility (the “Existing Senior Credit Facility”) by increasing the maximum facility amount from $100,000,000 to $500,000,000 and increasing the total borrowing base to $100,000,000, adding additional lenders, extending the maturity date and making other amendments on the terms set forth in the Summary of Principal Terms and Conditions attached hereto as Annex I (the “Term Sheet”). As used in this letter, the “Amendment” means the proposed amendment described in this letter and the Term Sheet and the “Amended Senior Credit Facility” means the Existing Senior Credit Facility as amended by such proposed Amendment. All transactions described above, together with the financing contemplated hereby, are sometimes referred to herein as the “Transactions”. Capitalized terms used in this letter but not defined herein shall have the meanings given to them in the Term Sheet.

SunTrust Bank is pleased to commit to provide the full amount of the $100,000,000 initial increased Borrowing Base, subject to the terms and conditions set forth in this letter and the Term Sheet (collectively, this “Commitment Letter”). You hereby appoint SunTrust Robinson Humphrey, Inc. to act, and the Arranger agrees to act, as sole lead arranger and book manager for the Amended Senior Credit Facility, subject to the terms and conditions of this Commitment Letter.

The Lead Arranger reserves the right, before or after the execution of the Financing Documentation, to syndicate all or a portion of SunTrust Bank’s commitment to one or more other financial institutions that will become parties to the Financing Documentation (such financial institutions, the “Lenders”) and the commitment of SunTrust Bank hereunder shall be reduced dollar-for dollar as and when the corresponding commitments are received. The Company understands that the Lead Arranger intends to commence such syndication efforts promptly.

The Arranger will manage all aspects of the syndication of the Amended Senior Credit Facility in consultation with SunTrust Bank and the Company, including the timing of all offers to potential Lenders, the determination of all amounts offered to potential Lenders, the selection of Lenders, the allocation of commitments, and the determination of compensation and titles (such as co-agent, managing agent, etc.) given, if any, to such Lenders. The Company agrees that no other agents, co-agents or arrangers will be appointed, or other titles conferred, without the prior written consent of the Lead Arranger, and that no Lender will receive any compensation for its commitment to, or participation in, the Amended Senior Credit Facility except as expressly set forth in the Term Sheet or the Fee Letter (as defined below), or as otherwise agreed to and offered by the Arranger.

To ensure an orderly and effective syndication of the Amended Senior Credit Facility, the Company further agrees that until the earlier of termination of this Commitment Letter and a Successful Syndication (as defined in the Fee Letter), the Company will not, and will not cause or permit any of its affiliates or agents to, arrange, sell, syndicate or issue, attempt to arrange, sell, syndicate or issue, announce or authorize the announcement of the arrangement, sale, syndication or issuance of, or engage in discussions concerning the arrangement, sale, syndication or issuance of, any credit facility or debt security (including any renewals thereof) except with the prior written consent of the Arranger.

The undertakings and obligations of SunTrust under this Commitment Letter are subject to: (i) the preparation, execution and delivery of mutually acceptable loan documentation, including an amendment to the Existing Credit Agreement incorporating substantially the terms and conditions outlined in this Commitment Letter; (ii) the accuracy of all representations that the Company makes to SunTrust (including those in Section D below) and all information that the Company furnishes to SunTrust, and the absence of any information or other matter being disclosed after the date hereof that is inconsistent in a material and adverse manner with any information or other material disclosed to SunTrust; (iii) the completion, and the Company’s reasonable cooperation in connection with, our due diligence investigation and review, and our satisfaction in all material respects with the results thereof; (iv) the payment in full of all fees, expenses and other amounts payable hereunder and under the Fee Letter; (v) the compliance with the provisions of this Commitment Letter; (vi) the Closing Date on or prior to July 31, 2015; and (vii) the satisfaction of the other conditions set forth in the Term Sheet.
