SECTION 4. No Transfer; Other Actions.

(a) Prior to the termination of this Agreement, except as otherwise provided herein (including pursuant to Section 3), the Stockholder shall not, directly or indirectly: (i) transfer, assign, sell (including short sell), gift, hedge, pledge, grant a participation interest in, hypothecate or otherwise dispose of (whether by sale, liquidation, dissolution, dividend or distribution), enter into any derivative arrangement with respect to, create or permit to exist any Encumbrances (other than Permitted Encumbrances) on, or consent to any of the foregoing (collectively, “Transfer”), any or all of the Subject Shares, Subject Option / RSUs, Subject Restricted Shares or any other securities of the Company or any right or interest therein (“Subject Securities”) (for the avoidance of doubt, any Shares issued upon the exercise of any Subject Option / RSUs or Subject Restricted Shares that cease to be subject to any forfeiture or vesting conditions, in each case shall be subject to the restrictions set forth in this Section 4(a)); (ii) enter into any contract, option or other agreement, arrangement or understanding with respect to any such Transfer; (iii) grant or permit the grant of any proxy, power-of-attorney or other authorization or consent in or with respect to any Subject Security; (iv) deposit or permit the deposit of any of the Subject Shares into a voting trust, or enter into a voting agreement, understanding or arrangement with respect to any Subject Security; or (v) take or permit any other action that would in any way restrict, limit or interfere with the performance of the Stockholder’s obligations hereunder or the transactions contemplated hereby or otherwise make any representation or warranty of the Stockholder herein untrue or incorrect in any material respect.

The Stockholder agrees that he shall not, and shall cause each of his Affiliates not to, become a member of a “group” (as that term is used in Section 13(d) of the Exchange Act) with respect to any Subject Shares, warrants or any other voting securities of the Company for the purpose of opposing or competing with the transactions contemplated by the Merger Agreement. The Stockholder shall promptly (but in any event within one business day) advise Parent of any Acquisition Proposal or Product Transaction Proposal received by the Stockholder or any of his Affiliates, the material terms and conditions of any such Acquisition Proposal or Product Transaction Proposal (including any material changes thereto) and the identity of the Person making any such Acquisition Proposal or Product Transaction Proposal.

(d) The Stockholder irrevocably and unconditionally (i) waives and agrees not to exercise any appraisal rights in respect of the Subject Shares that may arise with respect to the Merger and (ii) agrees not to commence or join or participate in, and agrees to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Parent, Purchaser, the Company or any of their respective successors (A) challenging the validity of, or seeking to enjoin or delay the operation of, any provision of this Agreement or the Merger Agreement (including any claim seeking to enjoin or delay the acceptance of the Offer or the Closing) or (B) alleging a breach of any duty of any Person in connection with the Merger Agreement, this Agreement or the transactions contemplated hereby or thereby.

SECTION 5. Non-Solicitation.

(a) From and after the date of this Agreement, except as otherwise permitted pursuant to the Merger Agreement, the Stockholder agrees that he and his Affiliates (for purposes of this Agreement, the Company shall not be deemed to be an Affiliate of the Stockholder) shall not, and shall cause his or their Representatives not to, directly or indirectly engage in any conduct prohibited by Section 5.3 of the Merger Agreement.

(b) Notwithstanding anything to the contrary in this Agreement, solely to the extent the Company is permitted to take the actions set forth in Section 5.3(b) of the Merger Agreement with respect to an Acquisition Proposal or Product Transaction Proposal, the Stockholder will be free to participate in any discussions or negotiations regarding such Acquisition Proposal or Product Transaction Proposal with the Person making such Acquisition Proposal or Product Transaction Proposal, provided that (i) the Stockholder has not breached this Section 5 and (ii) such action by the Stockholder would be permitted to be taken by the Company pursuant to Section 5.3(b) of the Merger Agreement.

(b) Waiver. No failure on the part of any party hereto to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any party hereto in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy.

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 hereto to the terms and conditions of this Agreement.

(d) No Third-Party Beneficiaries. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person (other than the parties hereto) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of such parties and, in some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties. Consequently, Persons other than the parties hereto may not rely on the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

(e) Applicable Legal Requirements; Jurisdiction; Specific Performance; Remedies.

(i) This Agreement and any disputes arising from or relating to this Agreement (whether based in contract, tort, or otherwise) 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. In any action or proceeding arising out of or relating to this Agreement: (A) each of the parties hereto irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware and any state appellate court therefrom or, if (but only if) such court lacks subject matter jurisdiction, the United States District Court sitting in New Castle County in the State of Delaware and any appellate court therefrom (collectively, the “Delaware Courts”); and (B) each of the parties hereto 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 11(a). Each of the parties hereto irrevocably and unconditionally (1) agrees not to commence any such action or proceeding except in the Delaware Courts, (2) agrees that any claim in respect of any such action or proceeding may be heard and determined in the Delaware Courts, (3) waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the jurisdiction or laying of venue of any such action or proceeding in the Delaware Courts and (4) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in the Delaware Courts. 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.

(ii) 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. The parties acknowledge and agree that (A) the parties shall be entitled to 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 this Section 11(e) without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement and (B) the right of specific performance is an integral part of the transactions contemplated by this Agreement and without that right, the parties hereto would not have entered into this Agreement. Each of the parties hereto agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that the other party or parties hereto have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity. 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 11(e) shall not be required to provide any bond or other security in connection with any such order or injunction.

(iii) 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.

(f) Assignment. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the parties hereto and their respective successors and permitted assigns; provided, however, that neither this Agreement nor any of the rights hereunder may be assigned without the prior written consent of the other parties hereto, and any attempted assignment of this Agreement or any of such rights without such consent shall be void and of no effect; provided, further, however, that Parent or Purchaser may assign its rights under this Agreement to any one or more Affiliates at any time so long as Parent provides the other parties hereto with prior written notice of such assignment; provided that no such assignment shall relieve Parent of its obligations hereunder.

(g) 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.
