the transactions contemplated hereby have been duly and validly authorized by all necessary action on the part of the Stockholder. This Agreement has been duly and validly executed and delivered by the Stockholder and, assuming the due
authorization, execution and delivery by the Company and Parent, constitutes a legal, valid and binding obligation of the Stockholder, enforceable against the Stockholder in accordance with its terms, (i) except as may be limited by bankruptcy,
insolvency, moratorium or other similar laws affecting or relating to enforcement of creditors’ rights generally, and (ii) subject to general principles of equity (whether considered in a proceeding in equity or at law). 

2.4. No Conflict. Except for any filings as may be required by applicable federal securities laws, the execution and delivery of
this Agreement by the Stockholder does not, and the performance of this Agreement by the Stockholder will not, (a) require any consent, approval, authorization or permit of, or filing with or notification to, any Governmental Entity or any other
Person by the Stockholder; (b) conflict with, or result in any violation of, or default (with or without notice or lapse of time or both) under any provision of, the organizational documents of the Stockholder or any other agreement to which the
Stockholder is a party, or (c) conflict with or violate any judgment, order, notice, decree, statute, law, ordinance, rule or regulation (collectively “Laws”) applicable to the Stockholder or to the Stockholder’s property or assets.

respect to the Shares. Notwithstanding the foregoing, the Stockholder shall be permitted to Transfer a portion or all of the Shares owned by the Stockholder to an Affiliate (as defined in the New Stockholder Rights Agreement) (any such Affiliate to
whom Shares are Transferred, an “Affiliate Transferee”), provided such Affiliate Transferee shall agree to specifically assume and be bound by the provisions of this Agreement with respect to such Shares Transferred to it. 

3.2. Additional Shares. Prior to the termination of this Agreement, the Stockholder will promptly notify Parent of the number of
any new shares of Company Common Stock or any other Company Securities acquired directly or beneficially by the Stockholder, if any, after the date of this Agreement. Any such shares of Company Common Stock shall become “Shares” within the
meaning of this Agreement. 
 3.3. Nonsolicitation.  

(a) None of the Stockholder or any of its Subsidiaries shall (whether directly or indirectly through directors, officers, employees,

take any of the actions prohibited by clause (i), (ii) or (iii) of this sentence. The Stockholder shall immediately cease, and cause its representatives, advisors and other intermediaries to immediately cease, any and all existing activities,
discussions or negotiations with any parties conducted heretofore with respect to any of the foregoing. The Stockholder shall promptly inform its representatives and advisors of the Stockholder’s obligations under this Section 3.3. Any
violation of this Section 3.3 by any representative of the Stockholder or its Subsidiaries shall be deemed to be a breach of this Section 3.3 by the Stockholder. For purposes of this Section 3.3, the term “Person” means any person,
corporation, entity or “group,” as defined in Section 13(d) of the Exchange Act, other than, with respect to the Stockholder, the Company or any Subsidiaries of the Company. 

(b) Notwithstanding the foregoing, the Stockholder, directly or indirectly through its directors, officers, employees, representatives,
advisors or other intermediaries, may, prior to the Company Stockholders Meeting, engage in negotiations or discussions with any Person (and its representatives, advisors and intermediaries) that has made an unsolicited bona fide written Company
Acquisition Proposal not resulting from or arising out of a breach of Section 3.3(a) of this Agreement to the extent that the Company, its Subsidiaries and controlled Affiliates, officers, directors, representatives, advisors or other intermediaries
are permitted to do so under Section 7.4 of the Merger Agreement. 






 3.4. Restrictions on Hedging. Prior to the termination of this Agreement, without
