WITNESSETH:

WHEREAS, the Borrower, the Lenders and the Administrative Agent are parties to a certain Treasury Secured Revolving Credit Agreement, dated as of March 31, 2011 (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”; capitalized terms used herein and not otherwise defined shall have the meanings assigned to such terms in the Credit Agreement), pursuant to which the Lenders have made certain financial accommodations available to the Borrower;

NOW, THEREFORE, for good and valuable consideration, the sufficiency and receipt of all of which are acknowledged, the Borrower, the Lenders and the Administrative Agent agree as follows:

1. Consent. Notwithstanding anything to the contrary in the Credit Agreement and subject to the satisfaction of the conditions set forth in Section 3 below, the Lenders hereby consent to the Borrower’s repurchase of Common Stock from time to time, and waive any Default associated with such repurchase of Common Stock, provided that (i) at the time of each such repurchase no Default shall be continuing and (ii) the aggregate consideration paid for all such purchases of Common Stock pursuant to this Consent shall not exceed $10,000,000.

2. Amendment. Section 1.1 of the Credit Agreement is hereby amended by replacing the definition of “Commitment Termination Date” in its entirety with the following definition:

3. Conditions to Effectiveness of this Consent and Amendment. Notwithstanding any other provision of this Consent and Amendment and without affecting in any manner the rights of the Lenders hereunder, it is understood and agreed that this Consent and Amendment shall not become effective, and the Borrower shall have no rights under this Consent and Amendment, until the Administrative Agent shall have received (i) an arrangement fee in the amount of $125,000, payable to the Administrative Agent for its own account, (ii) such other fees as the Borrower has previously agreed to pay the Administrative Agent or any of its affiliates in connection with this Consent and Amendment, (iii) reimbursement or payment of its costs and expenses incurred in connection with this Consent and Amendment or the Credit Agreement (including reasonable fees, charges and disbursements of King & Spalding LLP, counsel to the Administrative Agent), (iv) executed counterparts to this Consent and Amendment from the Borrower and the Lenders and (v) a fully executed copy of that certain Consent, effective as of March 30, 2012, by and among the Borrower, Administrative Agent and other parties thereto, concerning the Second Amended and Restated Revolving Credit Agreement, dated as of December 6, 2011 (as amended, restated, supplemented or otherwise modified from time to time).

(d) This Consent and Amendment has been duly executed and delivered for the benefit of or on behalf of the Borrower and constitutes a legal, valid and binding obligation of the Borrower, enforceable against the Borrower in accordance with its terms except as the enforceability hereof may be limited by bankruptcy, insolvency, reorganization, moratorium and other laws affecting creditors’ rights and remedies in general; and

6. Effect of Consent and Amendment. Except as set forth expressly herein, all terms of the Credit Agreement, as amended hereby, and the other Loan Documents shall be and remain in full force and effect and shall constitute the legal, valid, binding and enforceable obligations of the Borrower to the Lenders and the Administrative Agent. The execution, delivery and effectiveness of this Consent and Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of the Lenders under the Credit Agreement, nor constitute a waiver of any provision of the Credit Agreement. This Consent and Amendment shall constitute a Loan Document for all purposes of the Credit Agreement.

7. Governing Law.

(a) This Consent and Amendment shall be construed in accordance with and be governed by the law (without giving effect to the conflict of law principles thereof) of the State of New York.

(b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the United States District Court of the Southern District of New York, and of any state court of the State of New York sitting in New York County and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Consent and Amendment or any other Loan Document or the transactions contemplated hereby or thereby, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York state court or, to the extent permitted by applicable law, such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

Nothing in this Consent and Amendment or in any other Loan Document will affect the right of any party hereto to serve process in any other manner permitted by law.
