(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”),
Frontier Acquisition Sponsor LLC (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 660 Madison Avenue, 19th Floor, New York, NY 10065 (or any successor location). In exchange therefor the Company shall
pay the Sponsor a sum of $10,000 per month on the Effective Date and continuing monthly thereafter until the Termination Date.
The 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
upon the consummation of the IPO and hereby irrevocably waives any Claim it 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 against the Trust Account for any
reason whatsoever.

by the parties hereto.

This
letter agreement shall be governed by, construed in accordance with, and interpreted pursuant to the laws of the State of New
York, without giving effect to its choice of laws principles that might apply the laws of another jurisdiction.
