On June 24, 2026, Bleichroeder and certain funds and managed accounts managed by Bleichroeder (collectively, the "Voting Agreement Parties") entered into a Voting and Support Agreement (a copy of which is attached as Exhibit 4.1 hereto) (the "Voting Agreement") with Buyer and the Issuer, pursuant to which the Voting Agreement Parties agreed, among other things, to (a) appear at any meeting of the stockholders of the Issuer or otherwise cause the Shares and shares of Preferred Stock beneficially owned held by the Voting Agreement Parties as of such date (such number of shares, the "Covered Shares") to be counted as present thereat for purposes of calculating a quorum and (b) vote (or cause to be voted) all of such Covered Shares (i) in favor of the Transaction; (ii) in favor of the approval to adjourn or postpone any meeting of the stockholders of the Issuer if there are not sufficient votes for adoption of the Purchase Agreement on such date; (iii) against any action or agreement that would reasonably be expected to result in a breach by the Issuer of Purchase Agreement; (iv) against any action, proposal, transaction or agreement that would reasonably be expected to prevent, impede, frustrate, interfere with, postpone, materially delay or adversely affect the consummation of the Transaction or the fulfillment of Buyer's or the Issuer's conditions under the Purchase Agreement and the Transaction Documents; and (v) against any Acquisition Proposal (as such term is defined in the Purchase Agreement), provided that, in each case, the Voting Agreement Parties shall not be required to vote in favor of the Transaction if, and only if, the Purchase Agreement has been amended or modified without the Voting Agreement Parties' consent to reduce the consideration payable to the Issuer or otherwise amend the material terms of the Purchase Agreement in a manner that is materially adverse to the stockholders of the Issuer. The Voting Agreement will terminate upon the earlier of (i) the conclusion of the meeting of the stockholders of the Issuer called to vote upon the Transaction at which a vote upon the Transaction has occurred and the Covered Shares have been voted as specified in accordance with the terms of the Voting Agreement, (ii) the termination of the Purchase Agreement in accordance with its terms and (iii) the date on which Buyer and the Voting Agreement Parties agree in writing to terminate the Voting Agreement.

On June 24, 2026, Bleichroeder entered into a letter agreement (a copy of which is attached as Exhibit 4.2 hereto) (the "Governance Letter Agreement") with Issuer pursuant to which the Issuer agreed, among other things, to (a) include in its upcoming proxy statement a proposal seeking stockholder approval of Bleichroeder's ability to convert Series B Preferred Stock in excess of 19.9% of Issuer's outstanding Common Stock and to exceed 19.9% of Issuer's outstanding stock generally; (b) for a three-year period, not to amend or modify its bylaws to prevent, impair or delay the ability of stockholders holding 10% or more of Issuer's outstanding capital stock from calling special meetings of stockholders, and to consult reasonably with Bleichroeder with respect to dividends, distributions, stock repurchases and other transactions providing liquidity to stockholders; (c) provide Bleichroeder with the right to nominate one designee, reasonably acceptable to the then-current board of directors, for election to the board of directors at each annual meeting of stockholders for so long as Bleichroeder holds at least 20% of Issuer's outstanding Common Stock, including for this purpose securities convertible into Common Stock without giving effect to any conversion limitations applicable to the Series B Preferred Stock, and a second such designee if Bleichroeder's ownership increases to 40% or more; (d) use reasonable best efforts to obtain the election of any such Bleichroeder designees and, upon Bleichroeder's request, to appoint any such designees then serving on the board of directors to any committee designated to review or oversee strategic alternatives for Issuer, subject to customary recusal requests in the event of any potential conflict of interest. The Governance Letter Agreement further contains Issuer's acknowledgment that the restrictions on business combinations under Section 203 of the Delaware General Corporation Law are no longer applicable to Bleichroeder, Bleichroeder's acknowledgment and agreement that the Board and its committees must satisfy applicable Nasdaq and SEC independence requirements, and Bleichroeder's agreement that, if it acquires more than 40% of Issuer's voting stock, it shall vote shares held above such threshold in the same proportion as shares voted by Issuer's other stockholders.
