GUARANTY

This Guaranty (this “Guaranty”) is by and among the Guarantors identified on the signature page hereto and each other Person that becomes a party hereto pursuant to Section 19 (each a “Guarantor”; together, the “Guarantor(s)”), for the benefit of FUNICULAR FUNDS, LP (the “Holder”), and is dated as of      , 2024 (the “Effective Date”).

WHEREAS, QT IMAGING HOLDINGS, INC. F/K/A GIGCAPITAL5, INC, a Delaware corporation (the “Borrower”), has entered into that certain Secured Convertible Note (as amended, restated, supplemented or otherwise modified from time to time, the “Note”) dated as of the Effective Date in favor of the Holder, pursuant to the Note Purchase Agreement, dated as of February 29, 2024 (the “Purchase Agreement”), among the Borrower, QT Imaging, Inc. (“QT Imaging”) and the Holder;

WHEREAS, Borrower is a party to the Business Combination Agreement, dated as of December 8, 2022 (the “Business Combination Agreement”), by and among Borrower, QT Imaging and QTI Merger Sub., Inc., a wholly-owned subsidiary of Borrower (“Merger Sub”), pursuant to which Merger Sub will merge with and into QT Imaging, with QT Imaging surviving the merger as a wholly owned subsidiary of Borrower (the “Merger” and, together with the other transactions contemplated by the Business Combination Agreement and any other agreement executed and delivered in connection therewith, the “Business Combination”). Following the closing of the Business Combination, Borrower will be renamed “QT Imaging Holdings, Inc.”

WHEREAS, to induce the Holder to extend credit to the Borrower as set forth in the Note, each Guarantor absolutely and unconditionally guarantees all of the Obligations (as such term is defined in the Note); and

WHEREAS, each Guarantor has agreed to absolutely and unconditionally, and jointly and severally, guarantee the Obligations.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which hereby are acknowledged by the parties hereto, each Guarantor hereby agrees as follows:

1. Definitions. Capitalized terms used herein but not otherwise defined herein shall have the respective meanings ascribed to such terms in the Note.

2. Guaranty. To induce the Holder to make the loan under the Note, each Guarantor hereby unconditionally guarantees, as primary obligor and not merely as surety, the prompt and complete payment and performance when due, whether by demand, acceleration or otherwise, of the Obligations in the currency in which and as such Obligations are to be paid or performed.

3. Guaranty Absolute. This is a guaranty of payment and not merely of collection. Each Guarantor’s obligations under this Guaranty shall be absolute and unconditional, irrespective of: (a) any lack of capacity or authority of the Borrower or any lack of validity, regularity or enforceability of any provision of any Loan Document or other agreement relating to the Obligations; (b) any change in the amount, time, manner or place of payment of, or in any other term of, all or any of the Loan Documents or Obligations, or any other amendment or waiver of or any consent to departure from any of the terms of any Loan Document or Obligation, (c) any variation, extension, waiver, compromise or release of any or all of the Obligations or of any security from time to time provided therefor, (d) any release or amendment or waiver of, or consent to departure from, any other Guarantor or any other guaranty or support document, or any exchange, release or non-perfection of any collateral, for all or any of the Loan Documents or

Obligations; or (e) any present or future law, regulation or order of any jurisdiction (whether of right or in fact) or of any agency thereof purporting to reduce, amend, restructure or otherwise affect any term of any Loan Document or Obligation. This Guaranty shall not be affected by any circumstance (other than complete, irrevocable payment or performance) that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor. The Holder makes no representation or warranty in respect of any such circumstance and has no duty or responsibility whatsoever to any Guarantor in respect of the management and maintenance of the Obligations or any collateral therefor. The Holder shall not be obligated to file any claim relating to the Obligations in the event that the Borrower becomes subject to a bankruptcy, reorganization or similar proceeding, and the failure by the Holder to so file shall not affect any Guarantor’s obligations hereunder. In the event that any payment to the Holder in respect of any Obligations is rescinded or must otherwise be returned for any reason whatsoever, each Guarantor shall remain liable hereunder in respect of such Obligations, and each Guarantor’s obligations hereunder shall be reinstated, all as if such payment had not been made. Each Guarantor waives any right of set-off or counterclaim which such Guarantor may have or acquire against the Holder. Each Guarantor agrees that this Guaranty is a continuing guaranty and shall cover any present Obligations, and also all Obligations that have been created or may hereafter be created as such Obligations may be changed from time to time. Each Guarantor agrees that the Holder may deal freely with the Borrower with respect to the Obligations, without notice to such Guarantor, the same as if this Guaranty had not been given, all without in any way affecting such Guarantor’s obligations hereunder.

6. Set-Off. Upon the occurrence and during the continuance of any Event of Default, and without limiting any other rights of the Holder, the Holder in its sole discretion and without notice (which notice is expressly waived hereunder) and irrespective of whether (x) the Holder has made a demand for payment hereunder or under any other Loan Document or (y) the Obligations are due and payable, contingent, or unsecured, may also set-off any or all of the Obligations against any securities, cash, or other property of the Guarantor(s) in the possession of the Holder and against any obligations owed to the Guarantor(s) by the Holder to the extent that it does not impact the Holder’s ability to recover amounts owed to the Holder.

To the extent not referred to above, each Guarantor hereby waives all defenses (other than payment) which the Borrower may now or hereafter have to the payment of the Obligations, together with all suretyship defenses, which could otherwise be asserted by the Guarantor.

9. Waiver of Subrogation. Each Guarantor agrees not to exercise any rights which it may acquire by way of subrogation or by any indemnity, reimbursement or other agreement until all the Obligations have been indefeasibly paid in full in cash and the Loan Documents have been terminated. If any amount shall be paid to any Guarantor in violation of the preceding sentence, such amount shall be held in trust for the benefit of the Holder and shall forthwith be paid to the Holder to be credited and applied to the Obligations, whether matured or unmatured.

No failure on the part of the Holder to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the Holder of any right, remedy or power hereunder preclude any other or future exercise of any other right, remedy or power. Each and every right, remedy and power hereby granted to the Holder or allowed the Holder by law or other agreement shall be cumulative and not exclusive of any other right, remedy or power, and may be exercised by the Holder from time to time.
