GSRM GSR II Meteora Acquisition Corporation

Voting and Non-Redemption Agreement

On May 18, 2023, GSR II Meteora Acquisition Corp. (the “Company”) entered into voting and non-redemption agreements (each a “Voting and Non-Redemption Agreement” and collectively, the “Voting and Non-Redemption Agreements”) with unaffiliated third parties (each a “Non-Redeeming Stockholder” and collectively, the “Non-Redeeming Stockholders”) in exchange for such Non-Redeeming Stockholders agreeing to either not redeem or to reverse any previously submitted redemption request with respect to an aggregate of 6,033,000 shares of the Company’s Class A common stock sold in its initial public offering (“Non-Redeemed Shares”) in connection with the special meeting of stockholders called by the Company (the “Special Meeting”) to consider and approve, among other proposals, an extension of time for the Company to consummate an initial business combination (the “Extension Proposal”) from June 1, 2023 to July 1, 2023 (the “Initial Extension”), and to allow the Company, without another stockholder vote, to further extend the date to consummate an initial business combination on a monthly basis up to eight times by an additional one month each time after July 1, 2023 (each one month extension, a “Monthly Extension”), or later extended deadline date, by resolution of the Company’s board of directors, if requested by the GSR II Meteora Sponsor LLC (the “Sponsor”), until March 1, 2024, unless the closing of an initial business combination shall have occurred prior thereto (the “Extension”). In exchange for the foregoing commitments not to redeem such Non-Redeemed Shares, the Company has agreed to issue to the Non-Redeeming Stockholders an aggregate of 60,330 shares (the “Commitment Shares”) of the Company’s Class A common stock. If the Extension Proposal is approved, the Non-Redeeming Stockholders shall be entitled to receive up to 120,660 shares of the Company’s Class A common stock in connection with the Initial Extension and for each Monthly Extension that occurs prior to the closing of an initial business combination. The shares of Class A common stock issuable pursuant to the Initial Extension and each Monthly Extension shall accrue on a monthly basis and be issued to the Non-Redeeming Stockholders upon closing of an initial business combination (the “Share Issuance”). Pursuant to the Voting and Non-Redemption Agreements, the Non-Redeeming Stockholders are not required to vote shares of the Company’s Class A common stock acquired after the date of the Voting and Non-Redemption Agreement in favor of the Extension Proposal. The Company expects to enter into additional voting and non-redemption agreements with additional unaffiliated third parties on substantially the same terms as the Voting and Non-Redemption Agreements.

The Voting and Non-Redemption Agreements are expected to increase the likelihood that the Extension Proposal is approved by Company’s stockholders, and increase the amount of funds that remain in the Company’s trust account (the “Trust Account”) following the Special Meeting, relative to the amount of funds that would be expected to be remaining in the Trust Account following the Special Meeting had the Voting and Non-Redemption Agreements not been entered into and the shares subject to such agreements had been redeemed.

In connection with the Extension Proposal, the holders of the Company’s Class A common stock may elect to redeem their shares for their pro rata portion of the funds available in the Trust Account. The Company estimates that as of May 25, 2023, the date of the Special Meeting, the pro rata portion of the funds available in the Trust Account for the redemption of the Company’s Class A common stock will be approximately $10.39 per share.

The foregoing summary of the Voting and Non-Redemption Agreements do not purport to be complete and is qualified in its entirety by reference to the form of Voting and Non-Redemption Agreement filed as Exhibit 10.1 hereto and incorporated herein by reference.

Stockholders may withdraw redemption requests at any time prior to 5:00 p.m. Eastern time on May 23, 2023 (two business days before the Special Meeting) with respect to the Extension by contacting the Company’s transfer agent, Continental Stock Transfer & Trust Company, to the attention of SPAC Redemption Team at 1 State Street Plaza, 30th Floor, New York, New York 10004, or by email at spacredemptions@continentalstock.com.

Registration Rights Agreement

Pursuant to the Voting and Non-Redemption Agreement, each Non-Redeeming Stockholder is entitled to the registration rights set forth in the Registration Right Agreement (the “Registration Rights Agreement”), dated as of February 24, 2022, among the Company, Sponsor and the other parties thereto with respect to the Commitment Shares and the shares of Class A Common Stock issued pursuant the Share Issuance. Each Non-Redeeming Stockholder, the Company, and the Sponsor has executed a joinder to the Registration Rights Agreement (the “Joinder”) to join such Non-Redeeming Stockholder as a “Holder” (as defined in the Registration Rights Agreement”).

The foregoing summary of the Joinder does not purport to be complete and is qualified in its entirety by reference to the form of Joinder included in Exhibit 10.1 hereto and incorporated herein by reference.
