		(a)	 Effective as of the execution hereof, Section 1(i)
of the Trust Agreement is hereby amended and restated in its entirety as follows:

 

“(i) Commence liquidation of the
Trust Account only after and promptly after (x) receipt of, and only in accordance with, the terms of a letter from the Company (“Termination
Letter”) in a form substantially similar to that attached hereto as either Exhibit A or Exhibit B, as applicable,
signed on behalf of the Company by its Chief Executive Officer, President, Chief Financial Officer, Secretary or Chairman of the board

dissolution expenses), only as directed in the Termination Letter and the other documents referred to therein; or (y) upon (i) August
23, 2023 (or such earlier date as determined by the Board, in its sole discretion, and included in a public announcement) (the “Liquidation
Date”) and (ii) such later date as may be approved by the Company’s stockholders in accordance with the Company’s

which case the Trust Account shall be liquidated in accordance with the procedures set forth in the Termination Letter attached as Exhibit
B and the Property in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released

Agreement is intended to be in full compliance with the requirements for an amendment to the Trust Agreement as required by Section
6(c) and Section 6(d) of the Trust Agreement, and any defect in fulfilling such requirements for an effective amendment to the Trust
Agreement is hereby ratified, intentionally waived and relinquished by all parties hereto.

 Re: Trust Account - Termination Letter

 

Mr. Wolf and Ms. Gonzalez:

 

Pursuant to Section 1(i)
of the Investment Management Trust Agreement between AF Acquisition Corp. (the “Company”) and Continental Stock Transfer
& Trust Company (the “Trustee”), dated as of March 18, 2021 (as amended, the “Trust Agreement”),

set forth in the Trust Agreement.

 

In accordance with the terms
of the Trust Agreement, we hereby authorize you to liquidate all of the assets in the Trust Account and transfer the total proceeds into
a segregated account held by you on behalf of the Beneficiaries to await distribution to the Public Stockholders. The Company has selected
[__]1 as the effective date for the purpose of determining when the Public Stockholders will be entitled to receive their share
of the liquidation proceeds. You agree to be the Paying Agent of record and, in your separate capacity as Paying Agent, agree to distribute
said funds directly to the Company’s Public Stockholders in accordance with the terms of the Trust Agreement and the amended and
restated Certificate of Incorporation of the Company. Upon the distribution of all the funds, net of any payments necessary for reasonable
unreimbursed expenses related to liquidating the Trust Account, your obligations under the Trust Agreement shall be terminated, except
to the extent otherwise provided in Section 1(i) of the Trust Agreement.

 

	 	Very truly yours,

and Nicole Berg, Nicky V LLC and MSB Research Inc. (collectively, the “Signing Purchasers”). 
 WITNESSETH

 WHEREAS, the Borrower and the Required Purchases (as defined below) are parties to that certain Amended and Restated Note
Purchase Agreement dated February 20, 2015, as amended (the “2015 Purchase Agreement”), pursuant to which the Borrower issued to the Purchasers, among other things, 8% senior subordinated notes that mature on February 20,

2025, (ii) cancel the 2015 Warrants and the 2020 Warrants and (ii) issue new Warrants to the Purchasers as set forth herein; and 

WHEREAS, Section 5.13(a) of the 2015 Purchase Agreement provides that the 2015 Notes, 2015 Warrants and 2020 Warrants may be amended or
terminated by the Purchasers of Notes (as defined therein) representing at least a majority of the aggregate principal amount outstanding under all of the 2015 Notes (the “Required Purchasers”), and the undersigned Signing
Purchasers constitute the Required Purchasers. 
 NOW, THEREFORE, the parties hereby agree as follows:

issue to the Purchasers warrants to purchase that number of shares of Common Stock of the Borrower (collectively, the “2022 Warrants”) in accordance with such Purchaser’s individual allocation set forth opposite such
