Parent covenants and agrees with Stockholder that Parent will exercise the foregoing proxy consistent with the provisions of Section 2(a).

(c) For the avoidance of doubt, nothing in this Agreement prevents Stockholder from voting or issuing instructions, including any proxy to vote (or maintaining any such instructions or proxy), at its discretion all Covered Shares at the Company’s annual meeting of stockholders, on the matters described in the Company’s proxy statement disseminated to holders of Company Shares prior to the date hereof.

Without limiting the foregoing, it is agreed that any violation of the foregoing restrictions by any Representative of Stockholder shall be deemed to be a breach of this Section 3(b) by Stockholder. For purposes of this Section 3(b), the term “Person” shall not include Parent or any Parent Subsidiary or other affiliate of Parent or any of their Representatives. Notwithstanding anything to the contrary contained in this Agreement, Stockholder and its Representatives may in any event inform a Person that has made or, to the knowledge of the Company, is considering making any inquiry, indication of interest, proposal or offer relating to an Acquisition Proposal of the provisions of this Section 3(b).

(i) No Waiver. No failure or delay by any party in exercising any right, power, remedy or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any right, power or privilege.

(j) Governing Law. This Agreement shall be governed by, and construed in accordance with, and all disputes arising out of or in connection with this Agreement or the transactions contemplated hereby shall be resolved under, the Law of the State of Delaware regardless of the Law that might otherwise govern under applicable principles of conflicts of laws thereof.

(k) Jurisdiction. The parties agree that any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby (whether brought by any party or any of its Affiliates or against any party or any of its Affiliates) shall be brought in the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks subject matter jurisdiction, the Federal court of the United States of America sitting in Delaware, and any appellate court from any thereof, and each of the parties irrevocably consents to the exclusive jurisdiction of such courts (and of the appropriate appellate courts therefrom) (the “Delaware Courts”) in any such suit, action or proceeding and irrevocably and unconditionally waives, to the fullest extent permitted by Law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 10(f) shall be deemed effective service of process on such party.

(l) Waiver of Jury Trial. EACH OF THE PARTIES TO THIS AGREEMENT IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

(m) Interpretation. When a reference is made in this Agreement to Sections, such reference shall be to a Section of this Agreement unless otherwise indicated. Whenever the words “include”, “includes” or “including” are used in this Agreement they shall be deemed to be followed by the words “without limitation.” The word “or” shall not be exclusive. “Extent” in the phrase “to the extent” means the degree to which a subject or other thing extends, and such phrase does not mean simply “if.” References to “dollars” or “$” are to United States of America dollars. References (i) to any Law shall be deemed to refer to such Law as amended from time to time and to any rules, regulations or interpretations promulgated thereunder, (ii) to any Person include the successors and permitted assigns of that Person, (iii) from or through any date mean, unless otherwise specified, from and including or through and including, respectively, and (iv) to the “date hereof” means the date of this Agreement. The headings set forth in this Agreement are for convenience of reference purposes only and shall not affect or be deemed to affect in any way the meaning or interpretation of this Agreement or any term or provision hereof. When reference is made herein to a Person, such reference shall be deemed to include all direct and indirect Subsidiaries of such Person unless otherwise indicated or the context otherwise requires. All references herein to the Subsidiaries of a Person shall be deemed to include all direct and indirect Subsidiaries of such Person unless otherwise indicated or the context otherwise requires. The parties agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore, waive the application of any Law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

(n) Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by email (in .pdf or .tiff format) shall be sufficient to bind the parties to the terms and conditions of this Agreement.

(o) Expenses. Except as otherwise expressly provided in this Agreement, all direct and indirect costs and expenses incurred in connection with this Agreement shall be borne by the party incurring such expenses.

(p) No Ownership Interest. Nothing contained in this Agreement shall be deemed, upon execution, to vest in Parent or Merger Sub any direct or indirect ownership or incidence of ownership of or with respect to any Covered Shares. All rights, ownership and economic benefits of and relating to the Covered Shares shall remain vested in and belong to Stockholder, and Parent and Merger Sub shall have no authority to manage, direct, superintend, restrict, regulate, govern or administer any of the policies or operations of the Company or exercise any power or authority to direct Stockholder in the voting of any of the Covered Shares, except as otherwise provided in this Agreement.
