Dear Mr. Wolf and Ms. Gonzalez: 
 Pursuant to
Section 1(i) of the Investment Management Trust Agreement between Crixus BH3 Acquisition Company (the “Company”) and Continental Stock Transfer & Trust Company (the “Trustee”), made
effective as of October 4, 2021 (as amended, the “Trust Agreement”), this is to advise you that the Company did not effect an initial business combination (the “Business Combination”) within the
time frame specified in the Company’s Charter. Capitalized terms used but not defined herein shall have the meanings 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 [_________, 20__] 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 Charter. 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,
