 Re: Administrative Services Agreement 

Gentlemen: 
 This letter agreement by and between
Fortress Capital Acquisition Corp. (the “Company”) and FIG LLC (“FIG”), an affiliate of our sponsor, Fortress Capital Acquisition Sponsor LLC, dated as of the date hereof, will confirm our agreement that, commencing on the date
the securities of the Company are first listed on the New York Stock Exchange (the “Listing Date”), pursuant to a Registration Statement on Form S-1 and prospectus filed with the Securities and
Exchange Commission (the “Registration Statement”) and continuing until the earlier of the consummation by the Company of an initial business combination or the Company’s liquidation (in each case as described in the Registration
Statement) (such earlier date hereinafter referred to as the “Termination Date”): 
 (i) FIG shall make available to the Company,
at 1345 Avenue of the Americas, 46th Floor, New York, NY 10105 (or any successor location), certain office space, utilities and secretarial and administrative support as may be reasonably required by the Company. In exchange therefor, the Company
shall pay FIG the sum of $20,000 per month on the Listing Date and continuing monthly thereafter until the Termination Date; and 
 (ii) FIG
hereby irrevocably waives any and all right, title, interest, causes of action and claims of any kind as a result of, or arising out of, this letter agreement (each, a “Claim”) in or to, and any and all right to seek payment of any amounts
due to it out of, the trust account established for the benefit of the public stockholders of the Company and into which substantially all of the proceeds of the Company’s initial public offering will be deposited (the “Trust
Account”), and hereby irrevocably waives any Claim it may have in the future, which Claim would reduce, encumber or otherwise adversely affect the Trust Account or any monies or other assets in the Trust Account, and further agrees not to 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 constitutes the entire agreement and understanding of the parties hereto in respect of its subject matter and supersedes
all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they relate in any way to the subject matter hereof or the transactions contemplated hereby. 

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. 
 No party hereto may assign either this letter agreement or any of its rights, interests, or obligations hereunder without
the prior written approval 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 constitutes the entire relationship of the parties hereto, and any litigation between the parties (whether grounded in
contract, tort, statute, law or equity) 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.
