NOW, THEREFORE, in consideration of these premises and other valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree, as follows:

1. Amendments to Loan Agreement. Subject to the satisfaction of the conditions set forth herein, the Loan Agreement is amended as follows:

(a) The following definitions are hereby added to Section 1.1 of the Loan Agreement in the appropriate alphabetical order:

“Incremental Facility” has the meaning set forth in Section 2.6.

“Incremental Loan” has the meaning set forth in Section 2.6.

“Incremental Loan Termination Date” means 5:00 P.M. Dallas, Texas time on January 29, 2016 or such earlier date on which the Incremental Loan terminates as provided in this Agreement.

(b) The definition of “Commitment” in Section 1.1 of the Loan Agreement is hereby amended and restated in its entirety to read as follows:

“Commitment” means the obligation of Lender to make Borrowings pursuant to Section 2 in an aggregate principal amount at any time outstanding up to but not exceeding $30,000,000, subject, however, to (i) for the period following the Effective Date until the Incremental Loan Termination Date, a temporary increase pursuant to the Incremental Loan as set forth in Section 2.6 and (ii) termination pursuant to Section 10.2.

(c) The introductory paragraph of Section 2.1(a) of the Loan Agreement is hereby amended and restated in its entirety to read as follows:

(a) Borrowings. Subject to the terms and conditions of this Agreement (including, without limitation, Section 2.6), Lender agrees to make one or more revolving credit loans to Borrower from time to time from the date hereof to and including the Termination Date in an aggregate principal amount at any time outstanding up to but not exceeding the amount of the Commitment, provided that the aggregate amount of all Borrowings at any time outstanding shall not exceed the lesser of (i) the amount of the Commitment and (ii) the Borrowing Base. Subject to the foregoing limitations, and the other terms and provisions of this Agreement, Borrower may borrow, repay, and reborrow hereunder; provided that Borrower may not repay and reborrow amounts under the Incremental Loan. No Loan shall be funded or held with “plan assets” within the meaning of Section 3(42) of ERISA.

(d) Section 2.1(a)(ii) of the Loan Agreement is hereby amended and restated in its entirety to read as follows:

(ii) Repayment of Borrowings. Borrower shall repay the unpaid principal amount of all Borrowings on the Termination Date and, with respect to the Incremental Loan, on the Incremental Loan Termination Date, unless sooner due by reason of acceleration by Lender as provided in this Agreement.

(e) Section 2.1(a)(iii) of the Loan Agreement is hereby amended and restated in its entirety to read as follows:

(iii) Interest. The unpaid principal amount of the Borrowings shall, subject to the following sentence, bear interest as provided in the Revolving Credit Note. If at any time the rate of interest specified in the Revolving Credit Note would exceed the Maximum Rate but for the provisions thereof limiting interest to the Maximum Rate, then any subsequent reduction shall not reduce the rate of interest on the Borrowings below the Maximum Rate until the aggregate amount of interest accrued on the Borrowings equals the aggregate amount of interest which would have accrued on the Borrowings if the interest rate had not been limited by the Maximum Rate. Accrued and unpaid interest on the Borrowings shall be payable as provided in the Revolving Credit Note and on the Termination Date and, with respect to the Incremental Loan, on the Incremental Loan Termination Date.

(f) A new Section 2.6 is hereby added after Section 2.5 of the Loan Agreement to read as follows:

Section 2.6 Incremental Loan. Borrower has requested that Lender temporarily increase the principal amount of the Loan and the Lender has agreed to temporarily increase the principal amount of the Loan upon the terms and conditions as set forth herein (such increase, the “Incremental Facility” and the loan made pursuant to such Incremental Facility, the “Incremental Loan”) in an aggregate principal amount not to exceed $10,000,000. Such

Incremental Loan shall be due and payable in full on the Incremental Loan Termination Date; provided that Borrower may voluntarily prepay amounts due under the Incremental Loan prior to the Incremental Loan Termination Date without penalty. Subject to the foregoing limitations, and the other terms and provisions of this Agreement, Borrower may not repay and reborrow amounts under the Incremental Loan. Upon the Incremental Loan Termination Date, at Lender’s request, Borrower shall execute an amended and restated note reflecting a Commitment of $30,000,000.
