Unless otherwise specified herein, all capitalized terms used but not otherwise defined in this Agreement shall have the respective meanings ascribed to such terms in the Company’s Amended and Restated Certificate of Formation, dated as of August 28, 2025 (as may be amended from time to time, the “Restated Certificate”).

WHEREAS, the Restated Certificate provides that, subject to the requirements and limitations set forth therein, the Company shall take all Necessary Action to cause the slate of nominees recommended by the board of directors of the Company (the “Board”) for election as Directors of the Company to be consistent with Part G of Article V of the Restated Certificate, including for so long as Cynosure beneficially owns, on a collective basis, at least seven and one-half percent (7.5%) of the outstanding Common Stock, one (1) individual nominated for election to the Board by Cynosure (the “Cynosure Nominee”); and

WHEREAS, the Founder Investors and the Company wish to enter into this Agreement concerning the voting of shares of Common Stock held by the Founder Investors in favor of the election of the Cynosure Nominee and the Incumbent Nominees (as defined below).

1. Voting Provisions Regarding the Election of the Cynosure Nominee. Subject to Part G of Article V of the Restated Certificate, and for so long as Cynosure has the right to nominate for election to the Board the Cynosure Nominee pursuant to the terms of the Restated Certificate, each Founder Investor agrees to vote, or cause to be voted, all shares of Common Stock that it owns or over which such Founder Investor has voting control, from time to time and at all times, in favor of the election of the Cynosure Nominee that is nominated for election to the Board in accordance with Article V of the Restated Certificate (including in connection with the filling of any vacancy on the Board), whether by written consent or at a special or annual meeting of shareholders.

2. Voting Provisions Regarding the Election of Incumbent Directors. Subject to Part G of Article V of the Restated Certificate, and solely for the next two (2) consecutive annual meetings of the Company’s shareholders (excluding any adjournments or postponements thereof) occurring after the date of this Agreement, each Founder Investor agrees to vote, or cause to be voted, all shares of Common Stock that it owns or over which such Founder Investor has voting control, from time to time and at all times, in favor of the election of each incumbent member of the Board that is nominated for election to the Board in accordance with Article V of the Restated Certificate (such slate of nominees, the

“Incumbent Nominees”) at such annual meeting; provided that each of the Individual Founders continues to serve on the Board immediately prior to the commencement of such annual meeting, except where any such Individual Founder no longer serves on the Board by reason of resignation, death or incapacity. For the avoidance of doubt, nothing in this Section 2 shall limit or otherwise affect the obligations of the Founder Investors pursuant to Section 1 hereof to vote in favor of the Cynosure Nominee for so long as Cynosure retains its nomination rights under the Restated Certificate.

3. Voting Provisions Regarding the Election of Independent Directors. Solely for the next two (2) consecutive annual meetings of the Company’s shareholders, in the event that either of Kristina Cashman or Richard Federico shall fail to be nominated for election to the Board prior to the end of their respective term, in either event other than due to their respective death, resignation, disability or a determination by the Board in good faith that such nomination would be a violation of the Board’s fiduciary duties of care and loyalty, each Founder Investor agrees to refrain from voting, and to cause not to be voted, all shares of Common Stock that it owns or over which such Founder Investor has voting control, from time to time and at all times, in favor of the election of a different nominee to the Board nominated in the place of either of Kristina Cashman or Richard Federico without the written consent of the Cynosure Director.

4. Term. This Agreement shall be effective as of the date hereof and shall continue in effect until and shall terminate upon the earliest to occur of (a) the mutual written agreement of the Company, the Founder Investors and The Cynosure Group, LLC, (b) the Sunset Date and (c) the date on which Cynosure no longer has the right to nominate for election to the Board the Cynosure Nominee pursuant to the terms of the Restated Certificate.

5.3 Governing Law. This Agreement shall be governed by the internal law of the State of Texas, without regard to conflict of law principles that would result in the application of any law other than the law of the State of Texas.

5.4 Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act or other applicable law) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.
