Definitions. For purposes of this Agreement, capitalized terms used and not otherwise defined herein shall have the respective meanings ascribed to such terms in the Merger Agreement. When used in this Agreement, the following terms shall have the meanings assigned to them in this Section 1.

“Beneficially Own” or “Beneficial Ownership” has the meaning assigned to such term in Rule 13d-3 under the Exchange Act, and a Person’s beneficial ownership of securities shall be calculated in accordance with the provisions of such rule (in each case, irrespective of whether or not such rule is actually applicable in such circumstance). For the avoidance of doubt, “Beneficially Own” and “Beneficial Ownership” shall also include record ownership of securities.

“Beneficial Owner” shall mean the Person who Beneficially Owns the referenced securities.

Representations of Stockholder. Stockholder hereby represents and warrants to Parent that:

Ownership of Shares. Stockholder: (i) is the Beneficial Owner of, and has good and marketable title to, all of the Original Shares, free and clear of any proxy, voting restriction, adverse claim, or other Encumbrances, other than those created by this Agreement or under applicable federal or state securities laws; and (ii) has the sole voting and sole disposition power over all of the Original Shares. Except pursuant to this Agreement, there are no options, warrants, or other rights, agreements, arrangements, or commitments of any character to which Stockholder is a party relating to the pledge, disposition, or voting of any of the Original Shares and there are no voting trusts or voting agreements with respect to the Original Shares.

Disclosure of All Shares Owned. Stockholder does not Beneficially Own any shares of Company Common Stock other than the Original Shares.

Power and Authority; Binding Agreement. Stockholder has full limited liability company power and authority and legal capacity to enter into, execute, and deliver this Agreement and to perform fully Stockholder’s obligations hereunder (including delivering the proxy described in Section 3.B. below). This Agreement has been duly and validly executed and delivered by Stockholder and constitutes the legal, valid, and binding obligation of Stockholder, enforceable against Stockholder in accordance with its terms, except as may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, or other similar Laws affecting creditors’ rights generally.

No Conflict. The execution and delivery of this Agreement by Stockholder does not, and the consummation of the transactions contemplated hereby and the compliance with the provisions hereof will not, conflict with or violate any Law applicable to Stockholder or result in any breach or violation of, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration, or cancellation of, or result in the creation of any Encumbrance on any of the Shares pursuant to, any agreement or other instrument or obligation (including organizational documents) binding upon Stockholder or any of the Shares.

No Consents. No consent, approval, order, or authorization of, or registration, declaration, or filing with, any Governmental Entity or any other Person on the part of Stockholder is required in connection with the valid execution, delivery, or performance of this Agreement. For the avoidance of doubt, no consent of Stockholder’s spouse is necessary under any “community property” or other laws in order for Stockholder to enter into and perform its obligations under this Agreement.

No Litigation. There is no action, suit, investigation, or proceeding (whether judicial, arbitral, administrative, or otherwise) (each an “Action”) pending against, or, to the knowledge of Stockholder, threatened against or affecting, Stockholder that could reasonably be expected to materially impair or materially adversely affect the ability of Stockholder to perform Stockholder’s obligations hereunder or to consummate the transactions contemplated by this Agreement on a timely basis.

Agreement to Vote and Approve. Stockholder irrevocably and unconditionally agrees during the term of this Agreement, at any annual or special meeting of the Company called with respect to the following matters, and at every adjournment or postponement thereof, and for every action or approval by written consent or consents of the Company stockholders with respect to any of the following matters, to vote or cause the holder of record to vote the Shares: (i) in favor of (1) the Merger Agreement and the Merger and the other transactions contemplated by the Merger Agreement, and (2) any proposal to adjourn or postpone such meeting of stockholders of the Company to a later date if there are not sufficient votes to approve the Merger; and (ii) against (1) any Company Competing Proposal or any transactions contemplated thereby, (2) any action, proposal, transaction, or agreement which could reasonably be expected to result in a breach of any covenant, representation or warranty, or any other obligation or agreement of the Company under the Merger Agreement or of Stockholder under this Agreement, and (3) any action, proposal, transaction, or agreement that could reasonably be expected to impede, interfere with, delay, discourage, adversely affect, or inhibit the timely consummation of the Merger or the fulfillment of Parent’s, the Company’s, or Merger Sub’s conditions to Closing under the Merger Agreement or change in any manner the voting rights of any class of shares of the Company (including any amendments to the Company Organizational Documents).

Irrevocable Proxy. Stockholder hereby appoints Parent and any designee of Parent, and each of them individually, until the Expiration Time (as defined below) (at which time this proxy shall automatically be revoked), as its proxies and attorneys-in-fact, with full power of substitution and resubstitution, to vote or act by written consent during the term of this Agreement with respect to the Shares in accordance with Section 3A. This proxy and power of attorney is given to secure the performance of the duties of Stockholder under this Agreement. Stockholder shall take such further action or execute such other instruments as may be necessary to effectuate the intent of this proxy. This proxy and power of attorney granted by Stockholder shall be irrevocable during the term of this Agreement, shall be deemed to be coupled with an interest sufficient in law to support an irrevocable proxy, and shall revoke any and all prior proxies granted by Stockholder with respect to the Shares. The power of attorney granted by Stockholder herein is a durable power of attorney and shall survive the bankruptcy, death, or incapacity of Stockholder. The proxy and power of attorney granted hereunder shall terminate upon the termination of this Agreement.

No Voting Trusts or Other Arrangement. Stockholder agrees that, during the term of this Agreement, Stockholder will not, and will not permit any Person under Stockholder’s control to, deposit any of the Shares in a voting trust, grant any proxies with respect to the Shares, or subject any of the Shares to any arrangement with respect to the voting of the Shares, in each case other than those entered into with, or otherwise for the benefit of, Parent.

Transfer and Encumbrance. Stockholder agrees that during the term of this Agreement, Stockholder will not, directly or indirectly, transfer, sell, offer, exchange, assign, gift, pledge, convey any legal or Beneficial Ownership interest in, or otherwise dispose of (by merger (including by conversion into securities or other consideration), by tendering into any tender or exchange offer, by testamentary disposition, by operation of Law, or otherwise), or encumber (each, a “Transfer”), any of the Shares or enter into any contract, option, or other agreement with

respect to, or consent to, a Transfer of any of the Shares or Stockholder’s voting or economic interest therein. Any attempted Transfer of Shares or any interest therein in violation of this Section 5 shall be null and void. Notwithstanding the foregoing, this Section 5 shall not prohibit a Transfer of the Shares by Stockholder to: (a) any member of Stockholder’s immediate family; (b) a trust under which distributions may be made only to the Stockholder or any member of Stockholder’s immediate family; or (c) Stockholder’s executors, administrators, testamentary trustees, legatees, or beneficiaries, for bona fide estate planning purposes by will or by the laws of intestate succession/to an Affiliate of Stockholder; provided, that a Transfer referred to in this sentence shall be permitted only if, as a precondition to such Transfer, the transferee agrees in a writing, reasonably satisfactory in form and substance to Parent, to be bound by all of the terms of this Agreement.

Additional Shares. Stockholder agrees that all shares of Company Common Stock that Stockholder purchases, acquires the right to vote, or otherwise acquires Beneficial Ownership of, after the execution of this Agreement and prior to the Expiration Time shall be subject to the terms and conditions of this Agreement and shall constitute Shares for all purposes of this Agreement. In the event of any stock split, stock dividend, merger, reorganization, recapitalization, reclassification, combination, exchange of shares, or the like of the capital stock of the Company affecting the Shares, the terms of this Agreement shall apply to the resulting securities and such resulting securities shall be deemed to be “Shares” for all purposes of this Agreement.

Waiver of Appraisal and Dissenters’ Rights and Certain Other Actions.

Waiver of Appraisal and Dissenters’ Rights. To the fullest extent permitted by applicable Law, Stockholder hereby irrevocably and unconditionally waives, and agrees not to assert or perfect, any rights of appraisal or rights to dissent in connection with the Merger that Stockholder may have by virtue of ownership of the Shares.

Waiver of Certain Other Actions. Stockholder hereby agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any Action, derivative or otherwise, against Parent, the Company, or any of their respective Subsidiaries or successors: (i) 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 Closing); or (ii) to the fullest extent permitted under applicable Law, alleging a breach of any duty of the board of directors of the Company or Parent in connection with the Merger Agreement, this Agreement, or the transactions contemplated thereby or hereby.

Termination. This Agreement shall terminate upon the earliest to occur of (the “Expiration Time”): (a) the Effective Time; (b) the date on which the Merger Agreement terminates in accordance with its terms; and (c) the termination of this Agreement by mutual written consent of the Parties; provided, however, that (i) this Section 8 shall survive the termination of this Agreement and remain in full force and effect, and (ii) nothing in this Section 8 shall relieve or otherwise limit the liability of any Party for any intentional breach of this Agreement prior to such termination.

No Solicitation. Subject to Section 10, Stockholder shall not, and shall cause its Subsidiaries not to, and shall use its reasonable best efforts to cause its and its Subsidiaries’

Affiliates and Representatives not to: (a) directly or indirectly solicit, seek, initiate, knowingly encourage, or knowingly facilitate any inquiries regarding, or the making of, any submission or announcement of a proposal or offer that constitutes, or could reasonably be expected to lead to, any Company Competing Proposal; (b) directly or indirectly engage in, continue, or otherwise participate in any discussions or negotiations regarding, or furnish or afford access to any other Person any information in connection with or for the purpose of encouraging or facilitating, any proposal or offer that constitutes, or could reasonably be expected to lead to, any Company Competing Proposal; (c) enter into any agreement, agreement in principle, letter of intent, memorandum of understanding, or similar arrangement with respect to a Company Competing Proposal; (d) solicit proxies with respect to a Company Competing Proposal, or otherwise encourage or assist any Person in taking or planning any action that could reasonably be expected to compete with, restrain, or otherwise serve to interfere with or inhibit the timely consummation of the Merger in accordance with the terms of the Merger Agreement; or (e) initiate a stockholders’ vote or action by written consent of the Company’s stockholders with respect to a Company Competing Proposal.

No Agreement as Director or Officer. Stockholder has entered into this Agreement solely in the Stockholder’s capacity as the record and Beneficial Owner of the Shares (and not in any other capacity, including any capacity as a director or officer of the Company or its Subsidiaries). Nothing in this Agreement: (a) will limit or affect any actions or omissions taken by Stockholder in Stockholder’s capacity as a director or officer of the Company or its Subsidiaries, including in exercising rights under the Merger Agreement, and no such actions or omissions shall be deemed a breach of this Agreement; or (b) will be construed to prohibit, limit, or restrict Stockholder from exercising Stockholder’s fiduciary duties as a director or officer to the Company, its Subsidiaries, or their respective stockholders.

Further Assurances. Stockholder agrees, from time to time, and without additional consideration, to execute and deliver such additional proxies, documents, and other instruments and to take all such further action as Parent may reasonably request to consummate and make effective the transactions contemplated by this Agreement.

Stop Transfer Instructions. At all times commencing with the execution and delivery of this Agreement and continuing until the Expiration Time, in furtherance of this Agreement, Stockholder hereby authorizes the Company or its counsel to notify the Company’s transfer agent that there is a stop transfer order with respect to all of the Shares (and that this Agreement places limits on the voting and transfer of the Shares), subject to the provisions hereof and provided that any such stop transfer order and notice will immediately be withdrawn and terminated by the Company following the Expiration Time.

Specific Performance. Each Party hereto acknowledges that it will be impossible to measure in money the damage to the other Party if a Party fails to comply with any of the obligations imposed by this Agreement, that every such obligation is material and that, in the event of any such failure, the other Party will not have an adequate remedy at law or in damages. Accordingly, each Party agrees that injunctive relief or other equitable remedy, in addition to remedies at law or damages, is the appropriate remedy for any such failure and will not oppose the seeking of such relief on the basis that the other Party has an adequate remedy at law. Each Party

hereto agrees that it will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with the other Party’s seeking or obtaining such equitable relief.

Entire Agreement. This Agreement supersedes all prior agreements, written or oral, between the Parties with respect to the subject matter hereof and contains the entire agreement between the Parties with respect to the subject matter hereof. This Agreement may not be amended or supplemented, and no provisions hereof may be modified or waived, except by an instrument in writing signed by both Parties. No waiver of any provisions hereof by either Party shall be deemed a waiver of any other provisions hereof by such Party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such Party.

Notices. All notices, requests and other communications to any Party under, or otherwise in connection with, this Agreement shall be in writing and shall be deemed to have been duly given (a) if delivered in person; (b) if transmitted by electronic mail (“e-mail”) (but only if confirmation of receipt of such e-mail is requested and received; provided that each notice Party shall use reasonable best efforts to confirm receipt of any such email correspondence promptly upon receipt of such request); or (c) if transmitted by national overnight courier, in each case as addressed as follows:

Governing Law. This Agreement, and all claims or causes of action (whether based on contract, tort, or statute) arising out of or relating to, or in connection with this Agreement or the actions of any of the Parties in the negotiation, administration, performance, or enforcement hereof, shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of Laws of any jurisdiction other than those of the State of Delaware.

Each of the Parties irrevocably agrees that any claims or causes of action (whether based on contract, tort, or statute) with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by the other Party or its successors or assigns shall be brought and determined exclusively in the Court of Chancery of the State Of Delaware, or in the event (but only in the event) that such court does not have subject matter jurisdiction over such claim or cause of action, in the Federal Courts of the United States of America located in the State of Delaware. Each of the Parties agrees that service of process or other papers in connection with any such claim or cause of action in the manner provided for notices in Section 15 or in such other manner as may be permitted by applicable Law, will be valid and sufficient service thereof. Each of the Parties hereby irrevocably submits with regard to any such claim or cause of action for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court or tribunal other than the aforesaid courts. Each of the Parties hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim, or otherwise, in any claim or cause of action with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder: (i) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve process in accordance with this Section 16B.; (ii) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment, or otherwise); and (iii) to the fullest extent permitted by applicable Law, any claim that (x) the suit, action, or proceeding in such court is brought in an inconvenient forum, (y) the venue of such suit, action, or proceeding is improper, or (z) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY CONTROVERSY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT: (A) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER

Severability. If any term or provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be invalid, illegal, or unenforceable in any jurisdiction, such invalidity, illegality, or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal, or unenforceable, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the greatest extent possible.

Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument. A signed copy of this Agreement delivered by facsimile, email, or other means of electronic transmission shall be deemed to have the same legal effect as delivery of an original signed copy of this Agreement.

Interpretation. The section headings herein are for convenience of reference only, do not constitute part of this Agreement, and shall not be deemed to limit or otherwise affect any of the provisions hereof. Where a reference in this Agreement is made to a Section, 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.” As used herein, the word “extent” in the phrase “to the extent” means the degree to which a subject or other thing extends, and does not simply mean “if,” and the word “or” is not exclusive. The definitions of terms defined herein, or defined in the Merger Agreement and incorporated herein, shall apply equally to the singular and plural forms of such terms. The words “hereof,” “herein,” “hereby,” “hereto,” 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.

Assignment. Neither Party may assign any of its rights or obligations under this Agreement without the prior written consent of the other Party, except that Parent may assign, in its sole discretion, all or any of its rights, interests, and obligations hereunder to an Affiliate of Parent without the prior written consent of Stockholder. Subject to the immediately preceding sentence, this Agreement will be binding upon, inure to the benefit of, and be enforceable by the Parties and their respective successors and permitted assigns. Any assignment contrary to the provisions of this Section 16H. shall be null and void.

No Third-Party Beneficiaries. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person, other than the Parties and their respective successors and permitted assigns, any legal or equitable right, benefit, or remedy of any nature under or by reason of this Agreement.
