Re: Administrative Services Agreement 

Gentlemen: 
 This letter will confirm our
agreement that, commencing on the date the securities of GigCapital5, Inc. (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”), GigManagement, LLC
(“GigManagement”) shall make available to the Company, at 1731 Embarcadero Road, Suite 200, Palo Alto, CA 94303 (or any successor location), certain office space, utilities, and general office, receptionist and secretarial support
and other administrative services as may be reasonably required by the Company. In exchange therefor, the Company shall pay GigManagement the sum of $30,000 per month on the Listing Date and continuing monthly thereafter and will be entitled to
be reimbursed for any out-of-pocket expenses until the Termination Date. 

GigManagement hereby irrevocably waives any and all right, title, interest, causes of action and claims of any kind (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 as a result of, or arising out of, this agreement, 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 all 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.
