AGREEMENT

In consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, do hereby agree as follows:

SECTION 1 AGREEMENT TO TENDER AND VOTE

1.1 Agreement to Tender. Subject to the terms of this Agreement and other than with respect to Rollover Shares, each Stockholder agrees (i) to validly tender or cause to be tendered in the Offer all of such Stockholder’s Shares if no Company Adverse Change Recommendation has occurred and is continuing or (ii) to validly

tender or cause to be tendered in the Offer at least the Recommendation Change Requirement (rounded up to the nearest whole number of Shares) of Shares held by such Stockholder as set forth opposite such Stockholder’s name on Schedule A (as applicable, the “Recommendation Change Requirement”) if a Company Adverse Change Recommendation has occurred, pursuant to and in accordance with the terms of the Offer, free and clear of all Encumbrances (other than Permitted Encumbrances). Without limiting the generality of the foregoing, as promptly as practicable after, but in no event later than ten (10) Business Days after, the commencement (within the meaning of Rule 14d-2 under the Exchange Act) of the Offer (or, if later, the date of delivery of the letter of transmittal with respect to the Offer), each Stockholder shall, other than with respect to Rollover Shares, (i) deliver pursuant to the terms of the Offer (A) a letter of transmittal with respect to such Stockholder’s Shares or Recommendation Change Requirement, as applicable, complying with the terms of the Offer, (B) a Certificate or Certificates (or affidavits of loss in lieu thereof) representing such Shares or Recommendation Change Requirement, as applicable, or an “agent’s message” (or such other evidence, if any, of transfer as the Paying Agent may reasonably request) in the case of a Book-Entry Share, and (C) all other documents or instruments required to be delivered by stockholders of the Company pursuant to the terms of the Offer and/or (ii) instruct such Stockholder’s broker or such other Person that is the holder of record of any Shares or Recommendation Change Requirement, as applicable, beneficially owned by such Stockholder to tender such Shares or Recommendation Change Requirement, as applicable, pursuant to and in accordance with clause (i) of this Section 1.1 and the terms of the Offer. Each Stockholder agrees that, once any of such Stockholder’s Shares are tendered, such Stockholder will not withdraw or cause to be withdrawn any of such Shares from the Offer, unless and until this Agreement shall have been validly terminated in accordance with Section 5.2 or if a Company Adverse Change Recommendation is made after a Stockholder has tendered its shares, such Stockholder may withdraw its Shares provided that such Stockholder’s Recommendation Change Requirement remains tendered and such Stockholder shall tender such withdrawn Shares at such time that such Company Adverse Change Recommendation is no longer continuing.

1.2 Agreement to Vote. Subject to the terms of this Agreement, each Stockholder hereby irrevocably and unconditionally agrees that, during the time this Agreement is in effect, at any annual or special meeting of the stockholders of the Company, however called, including any adjournment or postponement thereof, and in connection with any action proposed to be taken by written consent of the stockholders of the Company, such Stockholder shall, in each case to the fullest extent that such Stockholder’s Shares are entitled to vote thereon: (i) if no Company Adverse Change Recommendation has occurred and is continuing, such Stockholder shall be present (in person or by proxy) and vote, or exercise its right to consent with respect to, all Shares held by such Stockholder (A) in favor of the adoption of the Merger Agreement and the approval of the Merger and (B) notwithstanding Section 4.4, against any Acquisition Proposal and any other proposal or action that would reasonably be expected to impede, interfere with, delay or postpone the Merger or change in any manner the voting rights of any class of Shares; and (ii) if a Company Adverse Change Recommendation has occurred and is continuing, such Stockholder shall be

present (in person or by proxy) and vote, or exercise its right to consent with respect to, at least the Recommendation Change Requirement (rounded up to the nearest whole number of Shares) of Shares held by such Stockholder (A) in favor of the adoption of the Merger Agreement and the approval of the Merger and (B) notwithstanding Section 4.4, against any Acquisition Proposal and any other proposal or action that would reasonably be expected to impede, interfere with, delay or postpone the Merger or change in any manner the voting rights of any class of Shares. Until such Shares are accepted for purchase in the Offer, each Stockholder shall retain at all times the right to vote the Shares in such Stockholder’s sole discretion, and without any other limitation, on any matters other than those set forth in this Section 1.2 that are at any time or from time to time presented for consideration to the Company’s stockholders generally.

Any action taken in violation of the foregoing sentence shall be null and void ab initio and such Stockholder agrees that any such prohibited action may and should be enjoined. If any involuntary Transfer of any or all of such Stockholder’s Shares shall occur (including, if applicable, a sale by such Stockholder’s trustee in any bankruptcy, or a sale to a purchaser at any creditor’s or court sale), the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and hold such Shares, subject to all of the restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect until valid termination of this Agreement. Such Stockholder agrees that it shall not, and shall cause each of its Affiliates not to, become a member of a “group” (as defined under Section 13(d) of the Exchange Act) with respect to any Company securities for the purpose of opposing or

competing with or taking any actions inconsistent with the transactions contemplated by the Merger Agreement. Notwithstanding the foregoing but subject to the Rollover Agreement, such Stockholder may make Transfers of Shares (a) to any “Permitted Transferee” (as defined below), in which case the Shares shall continue to be bound by this Agreement and provided that any such Permitted Transferee agrees in writing to be bound by the terms and conditions of this Agreement prior to the consummation of any such Transfer, or (b) as Parent may otherwise agree in writing in its sole discretion. A “Permitted Transferee” means, with respect to any Stockholder, (i) a spouse, lineal descendant or antecedent, brother or sister, adopted child or grandchild, or the spouse of any child, adopted child, grandchild, or adopted grandchild of such Stockholder, (ii) any charitable organization described in Section 170(c) of the Code, (iii) any trust, the beneficiaries of which include only the Persons named in clause (i) or (ii) of this definition, (iv) to any private equity fund affiliated with or managed by Stockholder or its fund, managed account or other similar vehicle Affiliates (and any investment vehicles wholly owned by such fund) and (if applicable) any direct or indirect general partner, managing member or similar control Person of any such Person or (v) any corporation, limited liability company, or partnership, the stockholders, members, and general or limited partners of which include only the Persons named in clause (i) or (ii) of this definition.

Such Stockholder consents to and hereby authorizes Parent and Purchaser to publish and disclose in all documents and schedules filed with the SEC, and any press release or other disclosure document that Parent or Purchaser reasonably determines to be necessary in connection with the Offer, the Merger and any transactions contemplated by the Merger Agreement, such Stockholder’s identity and ownership of the Shares, the existence of this Agreement and the nature of such Stockholder’s commitments and obligations under this Agreement, and such Stockholder acknowledges that Parent and Purchaser may, in Parent’s sole discretion, file this Agreement or a form hereof with the SEC or any other Governmental Body. Such Stockholder agrees to promptly give Parent any information it may reasonably require for the preparation of any such disclosure documents, and such Stockholder agrees to promptly notify Parent of any required corrections with respect to any written information supplied by it specifically for use in any such disclosure document, if and to the extent that such Stockholder shall become aware that any such information shall have become false or misleading in any material respect.

4.4 No Solicitation. Subject to Section 5.15, each Stockholder shall not, and, if not an individual, shall cause its Affiliates not to, and shall direct its other Representatives not to, directly or indirectly, (i) initiate or continue any solicitation, knowing encouragement, knowing facilitation, discussions or negotiations with any Persons with respect to an Acquisition Proposal or (ii) solicit, initiate or knowingly facilitate or knowingly encourage (including by way of furnishing non-public information) any inquiries regarding, or the making of any proposal or offer that constitutes, or could reasonably be expected to lead to, an Acquisition Proposal, (iii) engage in, continue or otherwise participate in any activities, discussions or negotiations regarding, or furnish to any other Person any non-public information in connection with or for the purpose of knowingly encouraging or facilitating, an Acquisition Proposal or any proposal or offer that could reasonably be expected to lead to an Acquisition Proposal, or (iv) endorse, approve or enter into any letter of intent, acquisition agreement, agreement in principle or similar agreement with respect to an Acquisition Proposal or any proposal or offer that could reasonably be expected to lead to an Acquisition Proposal or to prevent such Shareholder from complying with its obligations under this Section 4.4, or requiring or that would reasonably be expect to cause the Company to abandon, terminate, delay or fail to consummate, or that would otherwise reasonably impede, interfere with or be inconsistent with, the Offer or the Merger. Notwithstanding anything to the contrary provided in this Agreement, each Stockholder and its Affiliates and Representatives shall not be prohibited from participating in any discussions or negotiations with respect to a possible tender and support, voting or similar agreement in connection with an Acquisition Proposal in the event that the Company is permitted to take the actions set forth in Section 5.3 of the Merger Agreement with respect to such Acquisition Proposal.

(a) This Agreement shall be governed by, 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. Subject to Section 5.8(c), in any action or proceeding arising out of or relating to this Agreement or any of the transactions contemplated by this Agreement: (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 5.8 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 5.1 (Notices). 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.

(b) The parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the parties hereto do not perform their obligations under the provisions of this Agreement in accordance with its specified terms or otherwise breach such provisions. Subject to the following sentence, the parties acknowledge and agree that the parties shall be entitled to seek an injunction or injunctions, specific performance, or other equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in the courts described in Section 5.8(a) without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement. The parties will waive the defense of adequacy of a remedy at law and the parties hereto acknowledge and agree that any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 5.8(b) shall not be required to provide any bond or other security in connection with any such order or injunction.

(c) 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.

5.9 Entire Agreement; Counterparts. This Agreement and the schedules referred to herein, together with the Merger Agreement and the Rollover Agreement, constitute the entire agreement and supersedes all prior agreements and understandings, both written and oral, among or between the parties, with respect to the subject matter hereof. 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.

5.10 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.

5.11 Headings. The bold-faced headings contained in this Agreement are for convenience of reference only, shall not be deemed to be a part of this Agreement and shall not be referred to in connection with the construction or interpretation of this Agreement.

5.12 Mutual Drafting. Each party has participated in the drafting of this Agreement, which each party acknowledges is the result of extensive negotiations between the parties; accordingly, in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement.

5.13 Further Assurances. Parent, Purchaser and each Stockholder will execute and deliver, or cause to be executed and delivered, all further documents and instruments and use their respective reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable Legal Requirements, to perform their respective obligations under this Agreement.

5.14 Interpretation. Unless the context otherwise requires, as used in this Agreement: (i) “or” is not exclusive; (ii) “including” and its variants mean “including, without limitation” and its variants; (iii) words defined in the singular have the parallel meaning in the plural and vice versa; (iv) words of one gender shall be construed to apply to each gender; (v) the terms “Section” and “Schedule” refer to the specified Section or Schedule of or to this Agreement; and (vi) the words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement.

5.15 Capacity as Stockholder. Notwithstanding anything herein to the contrary, (i) each Stockholder signs this Agreement solely in such Stockholder’s capacity as a Stockholder of the Company, and not in any other capacity and this Agreement shall not limit or otherwise affect the actions of such Stockholder or any affiliate, employee or designee of such Stockholder or any of its affiliates in its capacity, if applicable, as an officer or director of the Company, and (ii) nothing herein shall in any way restrict a director or officer of the Company in the taking of any actions (or failure to act) in his or her capacity as a director or officer of the Company, or in the exercise of his or her fiduciary duties as a director or officer of the Company, or prevent or be construed to create any obligation on the part of any director or officer of the Company from taking any action in his or her capacity as such director or officer.

5.16 No Agreement Until Executed. This Agreement shall not be effective unless and until (i) the Merger Agreement is executed by all parties thereto, and (ii) this Agreement is executed by all parties hereto.

5.17 No Ownership Interest. Except as otherwise provided herein, nothing contained in this Agreement shall be deemed to vest in Parent or Purchaser any direct or indirect ownership or incidence of ownership of or with respect to the Shares.
