Re: Trust Account — Termination Letter

Ladies & Gentlemen:

Pursuant to paragraph 1(i) of the Investment Management
Trust Agreement between NorthView Acquisition Corp. (“Company”) and Continental Stock Transfer & Trust Company (“Trustee”),
dated as of December 20, 2021 (the “Trust Agreement”), this is to advise you that the Company has been unable to effect
a Business Combination with a Target Company within the time frame specified in the Company’s Amended and Restated Certificate of
Incorporation, as amended. Capitalized terms used herein and not otherwise defined 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 to 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 record 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 of the Trust Agreement.

(1) March 22, 2025 (which may be extended by the Corporation
monthly for up to three additional months (ultimately until as late as June 22, 2025)).

| Very truly yours,
