ARTICLE I

AGREEMENT TO TENDER AND VOTE

Section 1.1 Agreement to Tender. Subject to the terms of this Agreement, each Stockholder hereby agrees to validly and irrevocably tender (except in the case of termination of this Agreement or as otherwise provided by Law) or cause to be validly and irrevocably tendered (except in the case of termination of this Agreement or as otherwise provided by Law) in the Offer all of such Stockholder’s Subject Shares (other than Company Stock Options that are not exercised, Company RSUs that are not vested, and Company PSUs that are not settled during the term of this Agreement) pursuant to and in accordance with the terms of the Offer, free and clear of all Encumbrances, except for Permitted Encumbrances (in each case, as defined below). Without limiting the generality of the foregoing, as promptly as practicable after, but in no event later than eight (8) Business Days after, the commencement (within the meaning of Rule 14d-2 under the Exchange Act) of the Offer (or in the case of any Subject Shares acquired by such Stockholder subsequent to such eighth (8th) Business Day, as promptly as practicable after the acquisition of such Shares), as the case may be (but, if such Subject Shares are acquired prior to the expiration of the Offer, in no event later than the expiration of the Offer), each Stockholder shall deliver or cause to be delivered pursuant to the terms of the Offer (a) in the case of Subject Shares represented by a certificate or held in direct registry form through the Company’s transfer agent, a letter of transmittal with respect to all of such Stockholder’s Subject Shares complying with the terms of the Offer, together with the certificate(s) (or affidavits of loss in lieu thereof) representing all such Subject Shares that are certificated or (b) in the case of Shares held in book-entry form, written instructions to such Stockholder’s broker, dealer or other nominee that such Subject Shares be tendered, including a reference to this


Agreement, and requesting delivery of an “agent’s message” (or such other evidence, if any, of transfer as the Paying Agent may reasonably request) with respect to such Subject Shares, and (c) all other documents or instruments required to be delivered by the Stockholder pursuant to the terms of the Offer in order to effect the valid tender of such Stockholder’s Subject Shares in accordance with the Merger Agreement (it being understood that this sentence shall not apply to Company Stock Options that are not exercised, Company RSUs that are not vested or Company PSUs that are not settled during the term of this Agreement). Each Stockholder agrees that, once any of such Stockholder’s Subject Shares are tendered in accordance with the Offer, such Stockholder will not withdraw and will cause not to be withdrawn such Subject Shares from the Offer at any time, unless and until this Agreement shall have been validly terminated in accordance with Section 5.2. For clarity, no Stockholder shall be required, for purposes of this Agreement, to exercise any unexercised Company Stock Options held by such Stockholder. If the Offer is terminated or withdrawn by Purchaser, or the Merger Agreement is validly terminated prior to the Acceptance Time, Purchaser shall, and Parent shall cause Purchaser to, promptly return or cause to be returned all tendered Subject Shares to the applicable Stockholder no later than five (5) Business Days after the applicable termination or withdrawal.

Section 1.2 Agreement to Vote. Subject to the terms of this Agreement, each Stockholder hereby irrevocably and unconditionally agrees that, during the Agreement Period (as defined below), 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 (if permitted at such time) of the stockholders of the Company, in which the vote, consent or other approval of the stockholders of the Company is sought with respect to the Offer, the Merger, the Merger Agreement or any Acquisition Proposal, such Stockholder shall, in each case to the fullest extent that such Stockholder’s Subject Shares are entitled to vote thereon: (a) appear at each such meeting or otherwise cause all such Subject Shares to be counted as present thereat for purposes of determining a quorum; provided that this Section 1.2(a) shall not require any Stockholder to be present or vote any of its Subject Shares with respect to any amendment, modification or waiver of any provision of the Merger Agreement, or any amendment, modification or supplement to the Offer, that (x) terminates the Offer, or (y) would constitute or result in any of the matters set forth in clauses (A) through (G) of the last sentence of Section 1.1(a)(i) of the Merger Agreement (any of the foregoing, or the Company’s consent to any of the foregoing, an “Adverse Offer Modifications”); and (b) be present (in person or by proxy) and vote (or cause to be voted), or deliver (or cause to be delivered) a written consent (if permitted at such time) with respect to, all of its Subject Shares (i) against any Acquisition Proposal (other than the Merger), (ii) against any change in membership of the Company Board that is not recommended or approved by the Company Board, and (iii) against any other proposed action, agreement or transaction involving the Company that would reasonably be expected to, prevent, materially impair or delay the consummation of the Offer, the Merger or the other Contemplated Transactions, or result in any of the Offer Conditions or conditions to the consummation of the Merger under the Merger Agreement not being fulfilled. Each Stockholder shall retain at all times the right to vote such Stockholder’s Subject 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. Each Stockholder hereby authorizes Parent to direct the Company to impose stop orders to prevent the Transfer of any Subject Shares on the books of the Company in violation of this Agreement. Notwithstanding the foregoing, (x) any Stockholder that is an individual may Transfer Subject Shares (i) to any member of such Stockholder’s immediate family, (ii) to a trust for the sole benefit of such Stockholder or any member of such Stockholder’s immediate family, the sole trustees of which are such Stockholder or any member of such Stockholder’s immediate family, (iii) by will or under the laws of intestacy upon the death of such Stockholder, (iv) pursuant to, and in compliance with, a written plan in effect as of May 12, 2026 and provided to Parent prior to execution of this Agreement that meets the requirements of Rule 10b5-1 under the Exchange Act (and only with respect to those Shares subject to such written plan as of such date), or (v) to a partnership, limited liability company or other type of entity of which the Stockholder or its immediate family are the legal and beneficial owners of all of the outstanding equity securities or similar interests and (y) any Stockholder may Transfer Subject Shares to any Affiliate of such Stockholder; provided that in any such case (other than a Transfer pursuant to clause (x)(iv) above), such Transfer shall be permitted only if all of the representations and warranties in this Agreement with respect to such Stockholder would be true and correct at the time of such Transfer and the transferee shall have executed and delivered to Parent and Purchaser a counterpart to this Agreement pursuant to which such transferee shall be bound by all of the terms and provisions of this Agreement and agree and acknowledge that such Person shall constitute a Stockholder for all purposes of this Agreement.

Notwithstanding the foregoing, such Stockholder may make Transfers of its Subject Shares as Parent may agree in writing in its sole discretion.

Such Stockholder consents to and hereby authorizes the Company, Parent and Purchaser to publish and disclose in all documents and schedules filed with the SEC, including Schedule 14D-9, and any press release or other disclosure document that Parent, the Company or Purchaser reasonably determines to be necessary in connection with the Offer, the Merger and any of the other Contemplated Transactions, in each case regarding such Stockholder’s identity and ownership of the Subject Shares, the existence of this Agreement, the nature of such Stockholder’s commitments and obligations under this Agreement and any other information that Parent or the Company reasonably determines is required to be disclosed by Law, 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.

Whenever the words “include,” “includes,” or “including” are used in this Agreement, they will be deemed to be followed by the words “without limitation.” The words “hereof,” “herein,” “hereby,” “hereto,” and “hereunder” and words of similar import when used in this Agreement will refer to this Agreement as a whole and not to any particular provision of this Agreement. The word “or” will not be exclusive. Whenever used in this Agreement, any noun or pronoun will be deemed to include the plural as well as the singular and to cover all genders. This Agreement will be construed without regard to any presumption or rule requiring construction or interpretation against the party drafting or causing any instrument to be drafted. Any Law defined or referred to herein means such Law as from time to time amended, modified or supplemented, and all rules and regulations promulgated thereunder, unless otherwise specified therein. References to “days” shall mean “calendar days” unless expressly stated otherwise. Time is of the essence with respect to the performance of the obligations set forth in this Agreement and the provisions hereof will be interpreted as such.

Section 5.11 Further Assurances. Each Stockholder will execute and deliver, or cause to be executed and delivered, any additional documents and take such further actions as may be necessary, proper or advisable to comply with its obligations under this Agreement.

Section 5.12 Capacity as Stockholder. Each Stockholder signs this Agreement solely in such Stockholder’s capacity as a stockholder of the Company, and not, if applicable, in such Stockholder’s capacity as a director, officer or employee of the Company. 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, and no action taken in any such capacity as an officer or director of the Company shall be deemed to constitute a breach of this Agreement; provided, that, for the avoidance of doubt, nothing herein shall be understood to relieve any party to the Merger Agreement of any obligation under, or of any liability for breach of any provision of, the

Merger Agreement. Notwithstanding anything to the contrary in this Agreement or any other agreement or document executed or delivered in connection with the transactions contemplated hereby, nothing in this Agreement or any such other agreement or document shall: (a) release, waive, discharge, compromise, settle or affect any rights or claims that Stockholder or its Affiliates may have for (i) indemnification, advancement of expenses, contribution or reimbursement under any applicable Law, the certificate of incorporation, bylaws or other organizational documents of any person or party, any agreement or arrangement providing for such indemnification, advancement, contribution or reimbursement, or any insurance policy covering Stockholder or any of its Affiliates, (ii) any breach of or default under this Agreement, the Merger Agreement or any other agreement or document executed or delivered by Parent or Purchaser, (iii) any rights under this Agreement or the Merger Agreement, or (iv) any rights or claims that are expressly reserved, acknowledged or granted by this Agreement or any other agreement or document executed or delivered in connection with the transactions contemplated hereby; or (b) limit, impair or affect any rights or claims that Stockholder and/or its Affiliates may have against any other person or party arising out of or relating to any matter, event, circumstance, action, omission, transaction or occurrence that is outside the transactions contemplated hereby or the subject matter of this Agreement or any other agreement or document executed or delivered in connection therewith.

Section 5.15 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 Subject Shares. All rights, ownership and economic benefits of and relating to the Subject Shares shall remain vested in and belong to Stockholder, and neither Parent nor Purchaser shall have any authority to manage, direct, restrict, regulate, govern, or administer any of the policies or operations of the Company as a result of this Agreement or exercise any power or authority to direct Stockholder in the voting of any of the Subject Shares, except as otherwise provided herein.

Section 5.16 Stockholder Obligation Several and Not Joint. The obligations of each Stockholder hereunder shall be several and not joint, and no Stockholder shall be liable for any breach of the terms of this Agreement by any other Stockholder. Further, Parent and Purchaser agree that no Stockholder will be liable for claims, losses, damages, liabilities or other obligations of, or incurred by, the Company resulting from the Company’s breach of the Merger Agreement except to the extent that breach of such Stockholder’s obligations hereunder was also involved in such breach by the Company.

Section 5.17 Exclusion for Certain Company Stock Option Exercises. Notwithstanding anything to the contrary herein, Subject Shares surrendered to the Company in respect of payment of the exercise price upon exercise of Company Stock Options or for the withholding due upon such exercise shall not be Subject Shares subject to this Agreement, and this Agreement does not impose any restriction on such Transfer.
