In the event and to the extent that a Stockholder fails to vote the Subject Shares in accordance with Section 2.1(a) at least five (5) Business Days prior to (or takes or attempts to take any actions inconsistent with Section 2.1(a) prior to or at) any applicable meeting of the stockholders of Parent or pursuant to any applicable written consent of the stockholders of Parent, such Stockholder hereby appoints Parent and any designee of Parent, and each of them individually, as such Stockholder’s proxy, with full power of substitution and re-substitution, to vote, including by executing written consents, during the Initial Voting Period with respect to any and all of the Subject Shares on the matters and in the manner specified in Section 2.1(a). Each Stockholder shall take all further action or execute such other instruments as may be necessary to effectuate the intent of any such proxy. Each Stockholder affirms that the irrevocable proxy given by it hereby with respect to the Merger Agreement and the Contemplated Transactions is given to Parent by such Stockholder to secure the performance of the obligations of such Stockholder under this Support Agreement. It is agreed that Parent (and its designees) will use the irrevocable proxy that is granted by such Stockholder hereby only in accordance with applicable Laws and that, to the extent Parent (and its designees) uses such irrevocable proxy, it will only vote (or sign written consents in respect of) the Subject Shares subject to such irrevocable proxy with respect to the matters specified in, and in accordance with the provisions of, Section 2.1(a).

The proxy that may be granted hereunder shall terminate at the Expiration Time, but shall survive the death or incapacity of the granting Stockholder and any obligation of such Stockholder under this Support Agreement shall be binding upon the heirs, personal representatives and successors of such Stockholder until the Expiration Time.

Article III

Section 3.1 Subject Shares.

(a) Each Stockholder agrees during the Initial Voting Period it shall not, and shall not commit or agree to, without the prior written consent of Parent and the Company, (i) directly or indirectly, whether by merger, consolidation or otherwise, offer for sale, sell (including short sales), transfer, tender, pledge, encumber, assign or otherwise dispose of (including by gift or by operation of law) (collectively, a “Transfer”), or enter into any contract, option, derivative, hedging or other agreement or arrangement or understanding (including any profit-sharing arrangement) with respect to, or consent to or permit, a Transfer of any or all of the Subject Shares or any interest therein; (ii) grant any proxies or powers of attorney with respect to any or all of the Subject Shares or agree to vote (or sign written consents in respect of) the Subject Shares on any matter or divest itself of any voting rights in the Subject Shares that would conflict with the terms of this Support Agreement, or (iii) take any action that would have the effect of preventing or disabling such Stockholder from performing its obligations under this Support Agreement.

Each Stockholder agrees that any Transfer of Subject Shares not permitted hereby shall be null and void and that any such prohibited Transfer shall be enjoined. If any voluntary or involuntary Transfer of any Subject Shares covered hereby shall occur (including a sale by a Stockholder’s trustee in bankruptcy, or a sale to a purchaser at any creditor’s or court sale), the Permitted Transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial Permitted Transferee) shall take and hold such Subject Shares subject to all of the restrictions, liabilities and rights under this Support Agreement, which shall continue in full force and effect.

(b) In the event of a stock dividend or distribution, or any change in the Subject Shares by reason of any stock dividend or distribution, split-up, recapitalization, combination, conversion, exchange of shares or the like, the term “Subject Shares” shall be deemed to refer to and include the Subject Shares as well as all such stock dividends and distributions and any securities into which or for which any or all of the Subject Shares may be changed or exchanged or which are received in such transaction. Each Stockholder further agrees that, in the event such Stockholder purchases or otherwise acquires beneficial or record ownership of or an interest in, or acquires the right to vote or share in the voting of, any additional shares of Common Stock, in each case after the execution of this Support Agreement and prior to the Expiration Time, such Stockholder shall deliver promptly to the Company and Parent written notice of such event, which notice shall state the number of additional shares so acquired. Each Stockholder agrees that any such additional shares of Common Stock shall constitute Subject Shares for all purposes of this Support Agreement and shall be subject to the terms of this Support Agreement, including all covenants, agreements, obligations, representations and warranties set forth herein as if those additional shares were owned by such Stockholder on the date of this Support Agreement.

Section 3.2 Stockholder’s Capacity. All agreements and understandings made herein shall be made solely in each Stockholder’s capacity as a holder of the Subject Shares and not in any other capacity, including not in such Stockholder’s capacity as a director or officer of Parent. Notwithstanding anything herein to the contrary, nothing in this Support Agreement (including, for the avoidance of doubt, Section 3.7 below), shall in any way restrict a director of Parent (including any director who is an Affiliate of a Stockholder) in the taking of any actions (or failure to act) solely in his or her capacity as a director of Parent, or in the exercise of his or her fiduciary duties as a director of Parent, or prevent or be construed to create any obligation on the part of any director of Parent from taking any action in his or her capacity as such director, and no action taken solely in any such capacity as a director of Parent shall be deemed to constitute a breach of this Support Agreement.

Section 3.3 Other Offers. Except to the extent Parent is permitted to take such action pursuant to the Merger Agreement, each Stockholder (in such Stockholder’s capacity as such) shall not, and shall instruct and cause its Representatives not to, take any of the following actions: (a) solicit, initiate, knowingly encourage or knowingly facilitate an Acquisition Proposal; (b) furnish any non-public information regarding Parent to any Person in connection with or in response to an Acquisition Proposal (except as required by applicable Law or pursuant to a request by a Governmental Body); (c) engage in, enter into, continue or otherwise participate in any discussions or negotiations with any Person with respect to, or otherwise knowingly cooperate in any way with any Person (or any representative thereof) with respect to, any Acquisition Proposal; (d) approve, endorse or recommend or publicly propose to approve, endorse or recommend, any Acquisition Proposal; or (e) enter into any letter of intent or any Contract contemplating or otherwise relating to any Acquisition Transaction or publicly proposing to approve, endorse or recommend, any Acquisition Transaction; provided, however, that none of the foregoing restrictions shall apply to a Stockholder’s and its Representatives’ interactions with Parent, Merger Sub, the Company and their respective subsidiaries and Representatives; provided, further, that nothing in this Section 3.3 shall prevent a Stockholder from referring a Person to this Section 3.3 or to the Merger Agreement. Without limiting the foregoing, it is understood that any violation of the foregoing restrictions by any Representatives of the Stockholders shall be deemed to be a breach of this Section 3.3.

Section 3.4 Communications. Section 3.5 During the Initial Voting Period, each Stockholder shall not, and shall use its reasonable best efforts to cause its Representatives and Affiliates, if any, not to, directly or indirectly, make any press release, public announcement or other public communication that (a) criticizes or disparages this Support Agreement or the Merger Agreement or any of the transactions contemplated hereby and thereby or (b) is in opposition to the Stockholder Approval Matters, without the prior written consent of Parent and the Company, except as may be required by applicable Law in which circumstance such announcing party shall reasonably consult with the Company and Parent to the extent legally permissible prior to any such disclosure; provided, that the foregoing shall not limit or affect any actions taken by the Stockholders (or any affiliated officer or director of the Stockholders) that would be permitted to be taken by the Stockholders pursuant to the Merger Agreement.

SECTION 3.5 Voting Trusts. Except for this Support Agreement or otherwise disclosed to Parent prior to the date hereof, each Stockholder agrees that it will not, nor will it permit any entity under its control to, deposit any of its Subject Shares in a voting trust or subject any of its Subject Shares to any arrangement with respect to the voting of such Subject Shares that would restrict such Stockholder from performing its obligations under this Support Agreement.

SECTION 3.6 Waiver of Appraisal Rights. Each Stockholder hereby irrevocably and unconditionally waives, and agrees not to assert, exercise or perfect (or attempt to exercise, assert or perfect) any rights of appraisal or rights to dissent from the Merger or quasi-appraisal rights that it may at any time have under applicable Laws, including Section 262 of the DGCL.

(a) No filing with any Governmental Body, and no authorization, consent or approval of any other Person, is necessary for the execution of this Support Agreement by each of Parent and the Company and (b) none of the execution and delivery of this Support Agreement by Parent and the Company, the performance of Parent and the Company’s obligations hereunder, the consummation by Parent and the Company of the transactions contemplated hereby or compliance by Parent and the Company with any of the provisions hereof shall (i) conflict with or result in any breach of the organizational documents of Parent and the Company, as applicable, (ii) result in, or give rise to, a violation or breach of or a default under any of the terms of any material Contract, understanding, agreement or other instrument or obligation to which Parent or the Company is a party or by which Parent or the Company, as applicable, or their respective assets may be bound or (iii) violate any applicable order, writ, injunction, decree, judgment, statute, rule or regulation, except for any of the foregoing as would not reasonably be expected to impair Parent or the Company’s ability to perform its obligations under this Support Agreement.

Prior to the Release Date, none of the Stockholders (individually or jointly) nor any of their Representatives or Affiliates shall issue a press release, public announcement or other public communication with respect to Parent, the Company, the entry into this Support Agreement or the actions contemplated hereby without the prior written consent of Parent and the Company. Promptly following the execution and delivery of this Support Agreement, Parent will file a Current Report on Form 8-K (the “Form 8-K”), which will report the entry into this Support Agreement and file the Support Agreement as an exhibit thereto. The Stockholders shall be given a reasonable opportunity to review and comment on the Form 8-K or any other filing with the SEC made by Parent with respect to this Support Agreement, and Parent shall give reasonable consideration to any comments of the Stockholders. Parent acknowledges that the Stockholders may file this Support Agreement as an exhibit to the Stockholders’ Schedule 13D. In such event, Parent shall be given a reasonable opportunity to review and comment on such Schedule 13D filing made by the Stockholders with respect to this Support Agreement, and the Stockholders shall give reasonable consideration to any comments of Parent.

Section 7.2 Non-Disparagement. Each of the parties hereby agrees that, during the Initial Voting Period, neither it nor any of its Representatives or Affiliates or any of its or its Representatives’ and Affiliates’ respective agents, subsidiaries, officers, directors, managers, principals or managing members shall in any way publicly (or in any way reasonably expected to be made public) attack, disparage, call into disrepute, criticize, impugn, defame, slander or otherwise make any public statements or statements reasonably expected to be made public that would reasonably be expected to damage the business or reputation of any other party or such other party’s subsidiaries, Affiliates, officers (including any current officer of a party or a party’s subsidiaries who no longer serves in such capacity following the execution of this Support Agreement), directors (including any current director of a party or a party’s subsidiaries who no longer serves in such capacity following the execution of this Support Agreement) or employees, or any of their businesses, products or services, including, for the avoidance of doubt, the making of statements that would reasonably be expected to have any of the foregoing adverse consequences. Each party shall use its commercially reasonable efforts to cause its and its Representatives’ and Affiliates’ employees to comply with this Section 7.2. For the avoidance of doubt, the foregoing shall not restrict the ability of any person to comply with compelled testimony or production of information by legal process, subpoena or as part of a response to a request for information from any Governmental Body with purported jurisdiction over the party from whom information is sought.

Section 7.3 Further Actions. Subject to the terms and conditions set forth in this Support Agreement, each party hereto agrees to take any all actions and to do all things reasonably necessary to effectuate this Support Agreement.

Section 7.5 Amendments, Waivers, etc. This Support Agreement may not be amended except by an instrument in writing signed by all the parties hereto and specifically referencing this Support Agreement. No failure on the part of any party to exercise any power, right, privilege or remedy under this Support Agreement, and no delay on the part of any party in exercising any power, right, privilege or remedy under this Support 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. No party shall be deemed to have waived any claim arising out of this Support Agreement, or any power, right, privilege or remedy under this Support Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such party and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

Section 7.7 Interpretation; Construction. Headings of the Articles and Sections of this Support Agreement are for convenience of the parties only, and shall be given no substantive or interpretive effect whatsoever. Except as otherwise indicated, all references in this Support Agreement to “Exhibits”, “Sections” or “Schedules” are intended to refer to Sections of this Support Agreement and the Exhibits or Schedules to this Support Agreement. Any rule of construction to the effect that ambiguities are to be resolved against the drafting party shall not be applied in the construction or interpretation of this Support Agreement. As used in this Support Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.” For purposes of this Support Agreement, whenever the context requires: the singular number shall include the plural, and vice versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include masculine and feminine genders.

Section 7.8 Severability. Any term or provision of this Support 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 Support 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 Support Agreement is invalid or unenforceable, the parties 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 Support 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 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.

Section 7.9 Entire Agreement; Assignment. This Support Agreement constitutes the entire agreement, and supersedes all other prior agreements and understandings, both written and oral, between the parties, or any of them, with respect to the subject matter hereof; provided, however, that, as between the Company and Parent, to the extent of any conflict between the Merger Agreement and this Support Agreement, the terms of the Merger Agreement shall control and supersede any such conflicting terms. This Support Agreement will be binding upon, inure to the benefit of and be enforceable by the parties hereto and their respective successors and permitted assigns, and, in the case of each Stockholder, such Persons to which record or beneficial ownership of such Stockholder’s Subject Shares shall pass; provided, however, that neither this Support Agreement nor any of the rights, interests or obligations hereunder shall be assigned or delegated by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other parties, except that, without consent, each of Parent and the Company may assign all or any of its rights and obligations hereunder to any of its Affiliates that assume the rights and obligations of such party under the Merger Agreement, and any attempted assignment or delegation of this Support Agreement or any of the rights, interests or obligations by any of the parties without the other parties prior written consent shall be void and of no effect.

Section 7.10 Governing Law. THIS SUPPORT AGREEMENT AND ALL QUESTIONS RELATING TO THE INTERPRETATION OR ENFORCEMENT OF THIS SUPPORT AGREEMENT SHALL BE DEEMED TO BE MADE IN AND IN ALL RESPECTS SHALL BE INTERPRETED, CONSTRUED AND GOVERNED BY AND IN ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE WITHOUT REGARD TO THE CONFLICTS OF LAW PRINCIPLES THEREOF TO THE EXTENT THAT SUCH PRINCIPLES WOULD DIRECT A MATTER TO ANOTHER JURISDICTION.

Section 7.11 Specific Performance. The parties hereto acknowledge that any breach of this Support Agreement would give rise to irreparable harm for which monetary damages, even if applicable, would not be an adequate remedy, and would occur in the event that any party does not perform the provisions of this Support Agreement (including failing to take such actions as are required of it hereunder to consummate the transactions contemplated hereby) in accordance with its specified terms or otherwise breaches such provisions. Accordingly, the parties shall be entitled to seek a decree of specific performance, an injunction or other equitable relief to prevent breaches or threatened breaches of any of the provisions of this Support Agreement and to enforce specifically the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity. Each of the parties agrees that it will not oppose the granting of specific performance, an injunction or other equitable relief on the basis that any other party has an adequate remedy at law or that any award of specific performance or other equitable relief is not an appropriate remedy for any reason at law or in equity. Any party seeking an injunction or injunctions to prevent breaches of this Support Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.

Section 7.12 Submission to Jurisdiction. The parties hereby (a) irrevocably and unconditionally submit to the exclusive personal jurisdiction and venue of the Court of Chancery of the State of Delaware, New Castle County, or, if the Chancery Court declines jurisdiction, the United States District Court for the District of Delaware or, to the extent that neither of the foregoing courts has jurisdiction, the Superior Court of the State of Delaware, (b) agree that all claims in respect of such action or proceeding shall be heard and determined exclusively in accordance with clause (a) of this Section 7.12, (c) waive any objection to laying venue in any such action or proceeding in such courts, (d) waive any objection that such courts are an inconvenient forum or do not have jurisdiction over any party, and (e) agree that service of process upon such party in any such action or proceeding shall be effective if notice is given in accordance with Section 7.6 of this Support Agreement. Nothing in this Section 7.12, however, shall affect the right of any person to serve legal process in any other manner permitted by Law.

Section 7.13 Waiver of Jury Trial. EACH PARTY HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION (i) ARISING UNDER THIS SUPPORT AGREEMENT OR (ii) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS SUPPORT AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE. EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS SUPPORT AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS SUPPORT AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

Section 7.14 Counterparts. This Support Agreement may be executed in two or more counterparts (including by facsimile transmission or other means of electronic transmission, such as by electronic mail in “pdf” form), each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument, and shall become effective when one or more counterparts have been signed by each of the parties and delivered (by facsimile or otherwise) to the other parties.
