On August 25, 2024, BEP Special Situations IV LLC (“BEP SS IV”) and the Issuer entered into a debt commitment letter (the “Debt Commitment Letter”) pursuant to which BEP SS IV has agreed to purchase $3,000,000 in aggregate principal amount of additional senior secured convertible notes (the “Additional Convertible Notes”), contingent on the satisfaction of certain conditions set forth therein, including the Issuer’s consummation of an equity financing (the “Equity Financing”) and the amendment of the Amended and Restated Note Purchase Agreement, by and among the Issuer, BEP SS IV, Ascend Global Investment Fund SPC for and on behalf of Strategic SP and the other parties thereto. The terms of the Additional Convertible Notes are expected to be substantially similar to the Convertible Notes and the conversion price for the Additional Convertible Notes will be $0.9375, 125% of the price per share of the shares sold in the Equity Financing.

Pursuant to Section 2.2(a) of the Purchase Agreement and in satisfaction of a condition of the Company’s obligations under the Purchase Agreement, the undersigned irrevocably agrees with the Company that, from the date hereof until ninety (90) days after the Closing Date (such period, the “Restriction Period”) the undersigned will not offer, sell, contract to sell, hypothecate, pledge or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the undersigned or any Affiliate of the undersigned), directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), with respect to, any shares of Common Stock of the Company or securities convertible, exchangeable or exercisable into shares of Common Stock of the Company beneficially owned, held or hereafter acquired by the undersigned (the “Securities”). Beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act.

Notwithstanding the foregoing, and subject to the conditions below, the undersigned may transfer the Securities provided that, in the case of clauses (i) through (vi) below, (1) the Company receives a signed lock-up letter agreement (in the form of this Letter Agreement) for the balance of the Restriction Period from each donee, trustee, distributee or transferee, as the case may be, prior to such transfer, (2) any such transfer shall not involve a disposition for value, (3) such transfer is not required to be reported with the Securities and Exchange Commission in accordance with the Exchange Act and no report of such transfer shall be made voluntarily, and (4) neither the undersigned nor any donee, trustee, distributee or transferee, as the case may be, otherwise voluntarily effects any public filing or report regarding such transfers, with respect to transfer:

In addition, notwithstanding the foregoing, this Letter Agreement shall not restrict the delivery of shares of Common Stock to the undersigned upon (i) exercise of any options granted under any employee benefit plan of the Company, or the receipt of any shares upon the grant or vesting of any equity-based awards; provided that any shares of Common Stock or Securities acquired in connection with any such exercise will be subject to the restrictions set forth in this Letter Agreement, or (ii) the exercise of warrants; provided that such shares of Common Stock delivered to the undersigned in connection with such exercise are subject to the restrictions set forth in this Letter Agreement.

Furthermore, the undersigned may enter into any new plan (or amend any existing plan) established in compliance with Rule 10b5-1 of the Exchange Act; provided that (i) to the extent a public announcement or filing with the Securities and Exchange Commission, or other applicable regulatory authority, is made in connection with the establishment of such plan during the Restriction Period, such announcement or filing shall include a statement to the effect that no transfer of Common Stock may be made under such plan during the Restriction Period, and (ii) no sale of shares of Common Stock are made pursuant to such plan during the Restriction Period.

If the Company releases or waives any prohibition set forth in any other lock-up agreement executed pursuant to the Purchase Agreement (the “SPA Lock-Up Agreements”), the undersigned shall be immediately and fully released on the same terms from the applicable prohibitions set forth in such SPA Lock-Up Agreements.

The undersigned acknowledges that the execution, delivery and performance of this Letter Agreement is a material inducement to the Company to complete the transactions contemplated by the Purchase Agreement and the Company shall be entitled to specific performance of the undersigned’s obligations hereunder.

The undersigned hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by receiving a copy thereof sent to the Company at the address in effect for notices to it under the Purchase Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. The undersigned hereby waives any right to a trial by jury. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. The undersigned agrees and understands that this Letter Agreement does not intend to create any relationship between the undersigned and any Purchaser and that no Purchaser is entitled to cast any votes on the matters herein contemplated and that no issuance or sale of the Securities is created or intended by virtue of this Letter Agreement.

This Letter Agreement shall be binding on successors and assigns of the undersigned with respect to the Securities and any such successor or assign shall enter into a similar agreement for the benefit of the Company. This Letter Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.
