WHEREAS, the Sellers own 3,865,384 shares of the Company’s Class B common stock as of the date hereof;

WHEREAS, each share of Class B common stock is convertible into one share of Class A common stock (the “Common Stock”) at any time at the option of the Sellers, and each of the Sellers has agreed to transfer, assign, sell, convey and deliver a portion of the shares of Common Stock to the Company on the terms and conditions set forth in this Agreement;

WHEREAS, the Sellers and the Company have commenced an underwritten public offering (the “Public Offering”) of certain shares of Common Stock held by the Sellers (the “Underwritten Shares”);

NOW, THEREFORE, in consideration of the mutual covenants herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agree as follows:

1. Repurchase.

(a) At the Closing (as defined below), subject to the satisfaction of the conditions and to the terms set forth in paragraph 1(b), each Seller shall transfer, assign, sell, convey and deliver to the Company, and the Company shall purchase from such Seller, the number of shares of Common Stock set forth opposite such Seller’s name on Schedule A hereto (collectively, the “Repurchase Shares”). The per share purchase price for each Repurchase Share shall be equal to the per share price at which the Sellers sell the Underwritten Shares to the underwriters in the Public Offering (the “Per Share Purchase Price”).

(b) The obligations of the Company to purchase the Repurchase Shares shall be subject to the closing of the Public Offering pursuant to that certain Underwriting Agreement, dated as of May 1, 2013, by and among the Company, the Sellers and the underwriters named therein (the “Underwriting Agreement”).

At the Closing, the Sellers shall deliver to the Company, or as otherwise instructed by the Company, a duly executed stock power relating to the Repurchase Shares, and the Company agrees to deliver to each of the Sellers, by wire transfer of immediately available funds, an amount equal to the product of the Per Share Purchase Price multiplied by the aggregate number of Repurchase Shares of the respective Seller as set forth on the attached Schedule A.

(a) The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware. The Company has the requisite power and authority to execute, deliver and perform its obligations under this Agreement and to consummate the transactions contemplated hereby.

(b) This Agreement has been duly authorized, executed and delivered by the Company and constitutes a valid and binding agreement of the Company enforceable in accordance with its terms, except to the extent that enforcement thereof may be limited by bankruptcy, insolvency, reorganization or other laws affecting enforcement of creditors’ rights or by general equitable principles.

(c) The execution, delivery and performance by the Company of this Agreement and the consummation by the Company of the transactions contemplated by this Agreement will not (i) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its subsidiaries pursuant to, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject, (ii) result in any violation of the provisions of the charter or by-laws or similar organizational documents of the Company or (iii) result in the violation of any law or statute applicable to the Company or any of its subsidiaries or any judgment, order, rule or regulation of any court or arbitrator or governmental or regulatory authority having jurisdiction over the Company or any of its subsidiaries.

No transfer of property is being made and no obligation is being incurred in connection with the transactions contemplated by this Agreement with the intent to hinder, delay or defraud either present or future creditors of the Company or its subsidiaries.

(c) Complete Agreement. This Agreement and any other agreements ancillary thereto and executed and delivered on the date hereof embody the complete agreement and understanding between the parties and supersede and preempt any prior understandings, agreements, or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way.

Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by any of the parties without the prior written consent of the other parties. Subject to the preceding sentence, this Agreement shall bind and inure to the benefit of and be enforceable by each of the Sellers and the Company and their respective successors and permitted assigns.

(g) Governing Law; Jurisdiction. This Agreement and all disputes arising out of or related to this Agreement (whether in contract, tort or otherwise) will be governed by and construed in accordance with the laws of the State of Delaware. EACH OF THE PARTIES TO THIS AGREEMENT IRREVOCABLY WAIVES ANY AND ALL RIGHTS TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT. Each of the parties (i) irrevocably submits to the personal jurisdiction of any state or federal court sitting in Wilmington, Delaware, as well as to the jurisdiction of all courts to which an appeal may be taken from such courts, in any suit, action or proceeding relating to or arising out of, under or in connection with this Agreement, (ii) agrees that all claims in respect of such suit, action or proceeding, whether arising under contract, tort or otherwise, shall be brought, heard and determined exclusively in the Delaware Court of Chancery (provided that, in the event that subject matter jurisdiction is unavailable in that court, then all such claims shall be brought, heard and determined exclusively in any other state or federal court sitting in Wilmington, Delaware), (iii) agrees that it shall not attempt to deny or defeat such personal

jurisdiction by motion or other request for leave from such court, and (iv) agrees not to bring any action or proceeding relating to or arising out of, under or in connection with this Agreement or the Company’s business or affairs in any other court, tribunal, forum or proceeding.

(h) Mutuality of Drafting. The parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as jointly drafted by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

(i) Remedies. The parties hereto agree and acknowledge that money damages will not be an adequate remedy for any breach of the provisions of this Agreement, that any breach of the provisions of this Agreement shall cause the other parties irreparable harm, and that any party may in its sole discretion apply to any court of law or equity of competent jurisdiction (without posting any bond or deposit) for specific performance or other injunctive relief in order to enforce, or prevent any violations of, the provisions of this Agreement.

(j) Amendment and Waiver. The provisions of this Agreement may be amended, modified or waived only with the prior written consent of the Sellers and the Company. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement, nor shall any waiver constitute a continuing waiver. Moreover, no failure by any party to insist upon strict performance of any of the provisions of this Agreement or to exercise any right or remedy arising out of a breach thereof shall constitute a waiver of any other provisions or any other breaches of this Agreement.

(k) Further Assurances. Each of the Company and the Sellers shall execute and deliver such additional documents and instruments and shall take such further action as may be necessary or appropriate to effectuate fully the provisions of this Agreement.

(l) Expenses.
