Such irrevocable proxy shall be valid until the termination of this Agreement in accordance with its terms.

3. Representations and Warranties of Each Stockholder. Each Stockholder jointly and severally hereby represents and warrants to Parent and Merger Sub, on behalf of itself and each other Stockholder, as follows:

(a) The Stockholder has all requisite power and authority to execute and deliver this Agreement and to perform the Stockholder’s obligations under this Agreement. The execution, delivery and performance of this Agreement have been duly authorized by the Stockholder. This Agreement has been duly executed and delivered by the Stockholder and, assuming this Agreement constitutes a valid and binding obligation of Parent and Merger Sub, constitutes a valid and binding obligation of the Stockholder enforceable against the Stockholder in accordance with its terms, subject to (i) laws of general application relating to bankruptcy, insolvency and the relief of debtors, and (ii) rules of law governing specific performance, injunctive relief and other equitable remedies. The failure of the spouse, if any, of the Stockholder to be a party or signatory to this Agreement shall not (x) prevent the Stockholder from performing the Stockholder’s obligations contemplated hereunder or (y) prevent this Agreement from constituting the legal, valid and binding obligation of the Stockholder in accordance with its terms.

4

(b) The Securities and the certificates (or any book-entry notations used to represent any uncertificated shares of Company Common Stock) representing the Securities are now, and at all times during the term hereof will be, held by the Stockholder, or by a nominee or custodian for the benefit of the Stockholder, and the Stockholder has valid title to the Securities, free and clear of any Encumbrances (including voting trusts and voting commitments), except as would not limit the Stockholder’s ability to vote (or cause to be voted) the Securities in the manner provided herein and except as provided by this Agreement. As of the date of this Agreement, the Stockholder (i) is the record and/or beneficial owner of the Securities set forth on Exhibit A hereto and (ii) does not own of record or beneficially any Securities, other than the Securities set forth on Exhibit A hereto. The Stockholder has full power to vote (or cause to be voted) the Securities as provided herein.

(c) (i) No filing with, and no permit, authorization, consent or approval of any state, federal or foreign governmental authority is necessary on the part of the Stockholder for the execution and delivery of this Agreement by the Stockholder and the performance by the Stockholder of the Stockholder’s obligations under this Agreement and (ii) neither the execution and delivery of this Agreement by the Stockholder nor the performance by the Stockholder of the Stockholder’s obligations under this Agreement nor compliance by the Stockholder with any of the provisions hereof shall (x) result in the creation of an Encumbrance on any of the Securities or (y) violate any order, writ, injunction, decree, statute, rule or regulation applicable to the Stockholder or any of the Securities, except in the case of (x) or (y) for violations, breaches or defaults that would not in the aggregate materially impair the ability of the Stockholder to perform its obligations hereunder.

(d) As of the date hereof, there is no Legal Proceeding pending or, to the knowledge of the Stockholder, threatened against or affecting the Stockholder’s and/or any of its Affiliates before or by any Governmental Body that would reasonably be expected to impair the ability of the Stockholder to perform its obligations hereunder or to consummate the transactions contemplated hereby in a timely manner.

4. Assignment; Binding Effect. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other parties. Subject to the preceding sentence, this Agreement shall be binding upon, inure solely to the benefit of, and be enforceable by, the parties hereto and their respective permitted successors and assigns. Notwithstanding anything contained in this Agreement to the contrary, nothing in this Agreement, expressed or implied, is intended to or shall confer on any person other than the parties hereto or their respective heirs, successors, executors, administrators and assigns any rights, benefits, remedies, obligations or liabilities of any nature whatsoever under or by reason of this Agreement.

5. Termination. This Agreement, and all rights and obligations of the parties hereunder, shall terminate upon the first to occur of (a) the Effective Time, (b) the date on which the Merger Agreement is terminated in accordance with its terms, (c) the entry without the prior written consent of any Stockholder into any amendment or modification to the Merger Agreement or any waiver of any of Parent’s obligations under the Merger Agreement, in each case, that results in (i) a decrease in the Merger Consideration or (ii) a change in the form of Merger Consideration, or (d) the mutual written agreement of the parties to terminate this Agreement (the “Expiration Date”). In the event of termination of this Agreement pursuant to this Section 5, this Agreement will become null and void and of no effect with no liability on the part of any party hereto; provided, however, (A) the definitions in this Agreement, Section 5 and Section 8 shall each survive the termination of this Agreement and shall remain in full force and effect and (B) nothing set forth in this Section 5 or elsewhere in this Agreement shall relieve any Stockholder from any liability, or otherwise limit the liability, of any Stockholder for any Willful Breach by any Stockholder prior to such termination. For the avoidance of doubt, the representations and warranties herein shall not survive the termination of this Agreement.

6. Stockholder Capacity. Notwithstanding anything to the contrary in this Agreement, the parties acknowledge that (a) each Stockholder is entering into this Agreement solely in such Stockholder’s capacity as a record and/or beneficial owner of the Company Common Stock and not in such Stockholder’s capacity as a director, officer or employee of the Company (as applicable) or in such Stockholder’s capacity as a trustee or fiduciary of any Employee Plans and (b) nothing in this Agreement is intended to limit or restrict any Stockholder from taking any action or inaction or voting in such Stockholder’s sole discretion on any matter in his or her capacity as a director of the Company or in such Stockholder’s capacity as a trustee or fiduciary of any Employee Plans (if applicable), including, for the avoidance of doubt, taking any action permitted by Sections 4.3 and 5.1 of the Merger Agreement, and none of such actions in such capacity shall be deemed to constitute a breach of this Agreement. Neither Parent nor Merger Sub shall assert any claim that any action taken by such Stockholder in his capacity as a director of the Company violates any provision of this Agreement.

7. No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent or Merger Sub any direct or indirect ownership or incidence of ownership of or with respect to any Securities. All rights, ownership and economic benefits of and relating to the Securities shall remain vested in and belong to the Stockholders, 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 each Stockholder in the voting of any of the Securities, except as otherwise provided herein.

8. General Provisions.

No failure or delay by any party in exercising any right, power 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 other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by applicable law.

(c) All notices and other communications hereunder shall be in writing and shall be deemed to have been duly delivered and received hereunder (i) one business day after being sent for next business day delivery, fees prepaid, via a reputable international overnight courier service, (ii) upon delivery in the case of delivery by hand, (iii) if sent by email transmission prior to 6:00 p.m. recipient’s local time, upon transmission (provided that no “bounce back” or similar message of non-delivery is received with respect thereto) or (iv) if sent by email transmission after 6:00 p.m. recipient’s local time and no “bounce back” or similar message of non-delivery is received with respect thereto, the business day following the date of transmission; provided that in each case the notice or other communication is sent to the physical address or email address set forth beneath the name of such party below (or to such other physical address or email address as such party shall have specified in a written notice given to the other parties):

(d) When a reference is made in this Agreement to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

(e) 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 PDF shall be sufficient to bind the parties to the terms and conditions of this Agreement.

(f) This Agreement and the Merger Agreement constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof.

(g) This Agreement shall be governed and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof.

(h) (i) each of the parties irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Chancery Court of the State of Delaware and any state appellate court therefrom or, if such court lacks subject matter jurisdiction, the United States District Court sitting in New Castle County in the State of Delaware (it being agreed that the consents to jurisdiction and venue set forth in this Section 8(h) shall not constitute general consents to service of process in the State of Delaware and shall have no effect for any purpose except as provided in this paragraph and shall not be deemed to confer rights on any Person other than the parties hereto); and (ii) each of the parties irrevocably consents to service of process by first class certified mail, return receipt requested, postage prepaid, to the address at which such party is to receive notice in accordance with Section 8(c). The parties hereto agree 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 applicable Legal Requirements; provided, however, that nothing in the foregoing shall restrict any party’s rights to seek any post-judgment relief regarding, or any appeal from, such final trial court judgment. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING BETWEEN THE PARTIES HERETO ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

(i) If any provision of this Agreement or the application thereof to any party or set of circumstances shall, in any jurisdiction and to any extent, be finally held invalid or unenforceable by any rule of law or public policy, such term or provision shall only be ineffective as to such jurisdiction, and only to the extent of such invalidity or unenforceability, without invalidating or rendering unenforceable any other terms or provisions of this Agreement or under any other circumstances, and the parties shall negotiate in good faith a substitute provision which comes as close as possible to the invalidated or unenforceable term or provision, and which puts each party in a position as nearly comparable as possible to the position it would have been in but for the finding of invalidity or unenforceability, while remaining valid and enforceable.

8

(j) Each of the parties acknowledges that irreparable damage would occur in the event any provision of this Agreement was not performed in accordance with the terms hereof and agrees that the parties’ respective remedies at law for a breach or threatened breach of any of the provisions of this Agreement would be inadequate and, in recognition of that fact, each agrees that, in the event of a breach or threatened breach by any party of the provisions of this Agreement, in addition to any remedies at law or damages, each party, respectively, without posting any bond, shall be entitled to obtain equitable relief in the form of specific performance, a temporary restraining order, a temporary or permanent injunction or any other equitable remedy which may then be available in order to enforce the terms hereof.
