 “Company”) and continuing until the earlier of (i) the consummation by the Company of an initial business combination
and (ii) the Company’s liquidation (in each case as described in the Registration Statement) (such earlier date hereinafter referred
to as the “Termination Date”), Chain Bridge Group (the “Sponsor”) shall take steps
directly or indirectly to make available to the Company certain office space, secretarial and administrative services as may be required
by the Company from time to time, situated at 100 El Camino Real, Ground Suite, Burlingame, CA 94010 (or any successor location). In exchange
therefore, the Company shall pay the Sponsor a sum of up to $20,000 per month commencing on the Effective Date and continuing monthly
thereafter until the Termination Date. Sponsor hereby agrees that it does not have any right, title, interest or claim of any kind (a
 “Claim”) in or to any monies that may be set aside in a trust account (the “Trust Account”)
that may be established in connection with and upon the consummation of the IPO and hereby irrevocably waives any Claim it presently has
or may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with the Company and will not seek
recourse, reimbursement, payment or satisfaction of any Claim against the Trust Account or any monies or other assets in the Trust Account
for any reason whatsoever.

This letter agreement may
not be amended, modified or waived as to any particular provision, except by a written instrument executed by the parties hereto.


 


The parties may not assign
this letter agreement and any of their rights, interests, or obligations hereunder without the consent of the other party. Any purported
assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title
to the purported assignee.


 


This letter agreement shall

its choice of laws principles that will apply the laws of another jurisdiction.

constitute one and the same agreement.
