2021 by the U.S. Securities and Exchange Commission; 
 WHEREAS, the Company has entered into an Underwriting Agreement, dated as of
September 23, 2021, with Wells Fargo Securities, LLC and William Blair & Company, L.L.C., as representatives (the “Representatives”) of the underwriters (the “Underwriters”) named therein

for the benefit of the Company, the holders of the Public Common Stock and the Underwriters (the amount to be delivered to the Trustee, and any interest subsequently earned thereon, will be referred to herein as the
“Property”; the stockholders for whose benefit the Trustee shall hold the Property will be referred to as the “Public Stockholders”, and the Public Stockholders, the Company and the Underwriters will

Offering (including such proceeds from the exercise of the underwriters’ over-allotment option, if exercised) for each one-month extension of the time period to complete its initial Business Combination,
in exchange for a non-interest bearing, unsecured promissory note, as set forth in the Company’s Amended and Restated Certificate (as defined below); and 

WHEREAS, the Company and the Trustee desire to enter into this Agreement to set forth the terms and conditions pursuant to which the Trustee
shall hold the Property. 
 IT IS AGREED: 

1. Agreements and Covenants of Trustee. The Trustee hereby agrees and covenants to: 

(a) Hold the Property in trust for the Beneficiaries in accordance with the terms of this Agreement in the Trust Account, which Trust Account
shall be established by the Trustee at a branch of J.P. Morgan Chase Bank, N.A. (or at another U.S. chartered commercial bank with consolidated assets of $100 billion or more) and at a brokerage institution selected by the Trustee that is
satisfactory to the Company; 
 (b) Manage, supervise and administer the Trust Account subject to the terms and conditions set forth herein;

 (c) In a timely manner, upon the instruction of the Company, to invest and reinvest the Property in United States “government
securities” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), having a maturity of 185 days or less, and/or in any open ended investment company
registered under the Investment Company Act that holds itself out as a money market fund selected by the Company meeting the conditions of paragraphs (d)(2), (d)(3) and
(d)(4) of Rule 2a-7












 
promulgated under the Investment Company Act or any successor rule, which invests only in direct U.S. government treasury obligations, as determined by the Company. As used herein,
“government securities” shall mean United States Treasury Bills; the Trustee may not invest in any other securities or assets, it being understood that the Trust Account will earn no interest while account funds are uninvested awaiting the
Company’s instructions hereunder; while the account funds are invested or uninvested, the Trustee may earn bank credits or other consideration during such periods; 

(d) Collect and receive, when due, all principal and interest income arising from the Property, all of which income shall become part of the
Property and which interest income can then be released to the Company to the extent required to pay taxes when requested by the Company as provided for in Section 1(l) below; 

(e) Notify the Company and the Representatives of all communications received by it with respect to any Property requiring action by the
Company; 
 (f) Supply any necessary information or documents as may be requested by the Company or its authorized agents in connection with
the Company’s preparation of the tax returns relating to assets held in the Trust Account; 
 (g) Participate in any plan or proceeding
for protecting or enforcing any right or interest arising from the Property if, as and when instructed by the Company in writing to do so; 

(h) Render to the Company, and to such other person as the Company may instruct, monthly written statements of the activities of and amounts
in the Trust Account reflecting all receipts and disbursements of the Trust Account; 
 (i) Commence liquidation of the Trust Account only
after and promptly after (x) receipt of, and only in accordance with, the terms of a letter from the Company (“Termination Letter”) in a form substantially similar to that attached hereto as either
Exhibit A or Exhibit B signed on behalf of the Company by the Chief Executive Officer or Chief Financial Officer of the Company or by the Executive Chairman of the Board of Directors of the Company (the
“Board”) or other authorized officer of the Company, and, in the case of a Termination Letter in a form substantially similar to the attached hereto as Exhibit A, acknowledged and agreed to by the Representatives, and
complete the liquidation of the Trust Account and distribute the Property in the Trust Account, including interest (less up to $100,000 of interest that may be released to the Company to pay dissolution expenses in the case of a Termination Letter
in the form of Exhibit B hereto and which interest shall be net of any taxes payable), only as directed in the Termination Letter and the other documents referred to therein, or (y) the date which is the later of (i)
12 months after the closing of the IPO (or up to 18 months if the period to complete a Business Combination is extended as set forth in the Company’s Amended and Restated Certificate) and (ii) such later date as may be approved by the
Company’s stockholders in accordance with the Company’s Amended and Restated Certificate of Incorporation, as filed with the Secretary of State of the State of Delaware (the “Amended and Restated Certificate”) if a
Termination Letter has not been received by the Trustee prior to such date, in which case the Trust Account shall be liquidated in accordance with the procedures set forth in the form of letter attached hereto as Exhibit B and the
Property in the Trust Account, including interest (less up to $100,000 of interest that may be released to the Company to pay dissolution expenses in the case of a Termination Letter in the form of Exhibit B hereto and which
interest shall be net of any taxes payable), shall be distributed to the Public Stockholders of record as of such date; provided, however, that in the event the Trustee receives a Termination Letter in a form
substantially similar to Exhibit B hereto, or if the Trustee begins to liquidate the Property because it has received no such Termination Letter by the date specified in clause (y) of this Section 1(i), the
Trustee shall keep the Trust Account open until twelve (12) months following the date the Property has been distributed to the Public Stockholders; 

(j) Upon written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto
as Exhibit C (a “Tax Payment Withdrawal Instruction”), withdraw from the Trust Account and distribute to the Company the amount of interest earned on the Property requested by the Company to cover any tax
obligation owed by the Company as a result of assets of the Company or interest or other income earned on the Property, which amount shall be delivered directly to the Company by electronic funds transfer or other method of prompt payment, and the
Company shall forward such payment to the relevant taxing authority; provided, however, that to the extent there is not sufficient cash in the Trust Account to pay such tax obligation, the Trustee shall
liquidate such assets held in the Trust Account as shall be designated by the Company in writing to make such distribution so long as such distribution shall not result in a reduction in the principal amount per share initially deposited in the
Trust Account; provided, further, that if the tax to be paid is a franchise 












 
tax, the written request by the Company to make such distribution shall be accompanied by a copy of the franchise tax bill from the State of Delaware for the Company and a written statement from
the principal financial officer of the Company setting forth the actual amount payable (it being acknowledged and agreed that any such amount in excess of interest income earned on the Property shall not be payable from the Trust Account). The
written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility to look beyond said request; 

(k) Upon written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto
as Exhibit D (a “Stockholder Redemption Withdrawal Instruction”), the Trustee shall distribute to the Public Stockholders of record as of the applicable date the amount requested by the Company to be used
to redeem shares of Public Common Stock from Public Stockholders properly submitted in connection with a stockholder vote to approve an amendment to any provision of the Amended and Restated Certificate relating to pre-initial Business Combination
(as defined below) activity or the related stockholders’ rights. The written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility
to look beyond said request; and 
 (l) Not make any withdrawals or distributions from the Trust Account other than pursuant to
Sections 1(i), 1(j) or 1(k) above. 
 2. Agreements and Covenants of the Company. The Company hereby
agrees and covenants to: 
 (a) Give all instructions to the Trustee hereunder in writing, signed by the Company’s President, the
Executive Chairman of the Board or the Company’s Chief Executive Officer or Chief Financial Officer. In addition, except with respect to its duties under Sections 1(i), 1(j) and 1(k) above,
the Trustee shall be entitled to rely on, and shall be protected in relying on, any verbal or telephonic advice or instruction which it, in good faith and with reasonable care, believes to be given by any one of the persons authorized above to give
written instructions, provided that the Company shall promptly confirm such instructions in writing; 
 (b) Subject to
Section 4 hereof, hold the Trustee harmless and indemnify the Trustee from and against any and all expenses, including reasonable counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken
by it hereunder and in connection with any action, suit or other proceeding brought against the Trustee involving any claim, or in connection with any claim or demand, which in any way arises out of or relates to this Agreement, the services of the
Trustee hereunder, or the Property or any interest earned on the Property, except for expenses and losses resulting from the Trustee’s gross negligence, fraud or willful misconduct. Promptly after the receipt by the Trustee of notice of demand
or claim or the commencement of any action, suit or proceeding, pursuant to which the Trustee intends to seek indemnification under this Section 2(b), it shall notify the Company in writing of such claim (hereinafter referred to as the
“Indemnified Claim”). The Trustee shall have the right to conduct and manage the defense against such Indemnified Claim; provided, that the Trustee shall obtain the consent of the Company with respect
to the selection of counsel, which consent shall not be unreasonably withheld or delayed. The Trustee may not agree to settle any Indemnified Claim without the prior written consent of the Company, which such consent shall not be unreasonably
withheld or delayed. The Company may participate in such action with its own counsel; 
 (c) Pay the Trustee the fees set forth on
Schedule A hereto, including an initial acceptance fee, annual administration fee, and transaction processing fee which fees shall be subject to modification by the parties from time to time. It is expressly understood that the Property
shall not be used to pay such fees unless and until it is distributed pursuant to Sections 1(i) through 1(k) hereof. The Company shall pay the Trustee the initial acceptance fee and the first annual
administration fee at the consummation of the IPO, and, thereafter pay the annual fee. The Trustee shall refund to the Company the annual fee (on a pro rata basis) with respect to any period after the liquidation of the Trust Account. The Company
shall not be responsible for any other fees or charges of the Trustee except as set forth in this Section 2(c), Schedule A and as may be provided in Section 2(b) hereof; 

(d) In connection with any vote of the Company’s stockholders regarding a merger, capital stock exchange, asset acquisition, stock
purchase, reorganization or similar business combination involving the Company and one or more businesses (the “Business Combination”), provide to the Trustee an affidavit or certificate of the inspector of elections for the
stockholder meeting verifying the vote of such stockholders regarding such Business Combination; 
 (e) Provide the Representatives with a
copy of any Termination Letter(s) and/or any other correspondence that is sent to the Trustee with respect to any proposed withdrawal from the Trust Account promptly after it issues the same; and 












 (f) In the event that the Company directs the Trustee to commence liquidation of the Trust
Account pursuant to Section 1(i), the Company agrees that it will not direct the Trustee to make any payments not specifically authorized by this Agreement. 

3. Limitations of Liability. The Trustee shall have no responsibility or liability to: 

(a) Imply obligations, perform duties, inquire or otherwise be subject to the provisions of any agreement or document other than this
agreement and that which is expressly set forth herein; 
 (b) Take any action with respect to the Property, other than as directed
in Section 1 hereof, and the Trustee shall have no liability to any party except for liability arising out of the Trustee’s gross negligence, fraud or willful misconduct; 

(c) Institute any proceeding for the collection of any principal and income arising from, or institute, appear in or defend any proceeding of
any kind with respect to, any of the Property unless and until it shall have received written instructions from the Company given as provided herein to do so and the Company shall have advanced or guaranteed to it funds sufficient to pay any
expenses incident thereto; 
 (d) Change the investment of any Property, other than in compliance with Section 1(c); 

(e) Refund any depreciation in principal of any Property; 

(f) Assume that the authority of any person designated by the Company to give instructions hereunder shall not be continuing unless provided
otherwise in such designation, or unless the Company shall have delivered a written revocation of such authority to the Trustee; 
 (g) The
other parties hereto or to anyone else for any action taken or omitted by it, or any action suffered by it to be taken or omitted, in good faith and in the exercise of its own best judgment, except for the Trustee’s gross negligence, fraud or
willful misconduct. The Trustee may rely conclusively and shall be protected in acting upon any order, judgment, instruction, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Trustee, which counsel may be
the Company’s counsel), statement, instrument, report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein
contained) which the Trustee believes, in good faith, to be genuine and to be signed or presented by the proper person or persons. The Trustee shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this
Agreement or any of the terms hereof, unless evidenced by a written instrument delivered to the Trustee, signed by the proper party or parties and, if the duties or rights of the Trustee are affected, unless it shall give its prior written consent
thereto; 
 (h) Verify the accuracy of the information contained in the Registration Statement; 

(i) Provide any assurance that any Business Combination entered into by the Company or any other action taken by the Company is as
contemplated by the Registration Statement;

federal taxing authority or provide periodic written statements to the Company documenting the taxes payable by the Company, if any, relating to any interest income earned on the Property; 

(k) Prepare, execute and file tax reports, income or other tax returns and pay any taxes with respect to any income generated by, and
activities relating to, the Trust Account, regardless of whether such tax is payable by the Trust Account or the Company, including, but not limited to, income tax obligations, except pursuant to Section 1(j) hereof; or 

(l) Verify calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to
Sections 1(i), 1(j) and 1(k) hereof.

Claim to, or to any monies in, the Trust Account that it may have now or in the future. In the event the Trustee has any Claim against the Company under this Agreement, including, without limitation, under
Section 2(b) or Section 2(c) hereof, the Trustee shall pursue such Claim solely against the Company and its assets outside the Trust Account and not against the Property or any monies in the Trust Account.













 5. Termination. This Agreement shall terminate as follows: 

(a) If the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company shall use its reasonable
efforts to locate a successor trustee, pending which the Trustee shall continue to act in accordance with this Agreement. At such time that the Company notifies the Trustee that a successor trustee has been appointed and has agreed to become subject
to the terms of this Agreement, the Trustee shall transfer the management of the Trust Account to the successor trustee, including but not limited to the transfer of copies of the reports and statements relating to the Trust Account, whereupon this
Agreement shall terminate; provided, however, that in the event that the Company does not locate a successor trustee within ninety (90) days of receipt of the resignation notice from the Trustee, the
Trustee may submit an application to have the Property deposited with any court in the State of New York or with the United States District Court for the Southern District of New York and upon such deposit, the Trustee shall be immune from any
liability whatsoever; 
 (b) At such time that the Trustee has completed the liquidation of the Trust Account and its obligations in
accordance with the provisions of Section 1(i) hereof (which section may not be amended except as described in Section 6(c)) and distributed the Property in accordance with the provisions of the Termination
Letter, this Agreement shall terminate except with respect to Section 2(b). 
 6. Miscellaneous. 

(a) The Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth below with respect to funds
transferred from the Trust Account. The Company and the Trustee will each restrict access to confidential information relating to such security procedures to authorized persons. Each party must notify the other party immediately if it has reason to
believe unauthorized persons may have obtained access to such information, or of any change in its authorized personnel. In executing funds transfers, the Trustee will rely upon all information supplied to it by the Company, including, account
names, account numbers, and all other identifying information relating to a beneficiary, beneficiary’s bank or intermediary bank. Except for any liability arising out of the Trustee’s gross negligence, fraud or willful misconduct, the
Trustee shall not be liable for any loss, liability or expense resulting from any error in the information or transmission of the funds. 

(b) This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving effect
to conflict of laws. It may be executed in several counterparts, each one of which shall constitute an original, and together shall constitute but one instrument.

for Sections 1(i) and 1(k) hereof (each of which may not be modified, amended or deleted without the affirmative vote of a majority of the then outstanding shares of Common Stock; provided,
that no such amendment will affect any Public Stockholder who has otherwise indicated his election to redeem his shares of Common Stock in connection with a stockholder vote sought to amend this Agreement), this Agreement or any provision hereof may
be changed, amended or modified by a writing signed by each of the parties hereto. 
 (d) The Trustee may rely conclusively on the
certification from the inspector of elections referenced above and shall be relieved of all liability to any party for executing the proposed amendment in reliance thereon. The parties hereto consent to the jurisdiction and venue of any state or
federal court located in the City of New York, State of New York, for purposes of resolving any disputes hereunder. AS TO ANY CLAIM, CROSS-CLAIM OR COUNTERCLAIM IN ANY WAY RELATING TO THIS AGREEMENT, EACH PARTY WAIVES THE RIGHT TO TRIAL BY JURY.

 (e) Any notice, consent or request to be given in connection with any of the terms or provisions of this Agreement shall be in writing
and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested), by hand delivery or by facsimile transmission:

 Ladies and Gentlemen: 

Pursuant to Section 1(k) of the Investment Management Trust Agreement between GigCapital5, Inc., a Delaware
corporation (the “Company”) and Continental Stock Transfer & Trust Company (“Trustee”), dated as of September 23, 2021 (“Trust Agreement”), the Company hereby
requests that you deliver $[        ] of the principal and interest income earned on the Property as of the date hereof to a segregated account held by you for further transfer to the institutions representing
the Public Stockholders who have properly elected to have their shares of Public Common Stock redeemed by the Company as described below. Capitalized terms used but not defined herein shall have the meanings set forth in the Trust Agreement. 

The Company needs such funds to pay the Public Stockholders who have properly elected to have their shares of Public Common Stock redeemed by
the Company in connection with a stockholder vote to approve an amendment to the Company’s Amended and Restated Certificate of Incorporation that would affect the substance or timing of the Company’s obligation to redeem 100% of the shares
of Public Common Stock if the Company has not consummated an initial Business Combination within such time as is described in the Company’s Amended and Restated Certificate of Incorporation, or that would otherwise affect provisions thereof
relating to the Company’s pre-initial Business Combination activity or related stockholder rights. As such, you are hereby directed and authorized to transfer (via wire transfer) such funds
promptly upon your receipt of this letter to the financial institutions that have redeemed shares on behalf of the Beneficiaries.
