ARTICLE III.

EFFECTS OF THE MERGER

SECTION 3.01 Conversion of Securities.

(a) At the Effective Time, by virtue of the Merger and without any action on the part of GigCapital5, Merger Sub, the Company or the holders of any of the following securities or rights:

(i) each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (including shares issued upon the exercise or conversion of Company Options, Company Warrants and Company Convertible Notes, in each case prior to the Effective Time, but excluding any shares to be cancelled pursuant to Section 3.01(a)(ii)) shall be canceled and converted into (A) the right to receive a number of shares of GigCapital5 Common Stock equal to the Exchange Ratio (the “Per Share Merger Consideration”) and (B) the contingent right to receive a portion of the Merger Consideration Earnout Shares, if, as and when payable in accordance with the provisions of Section 3.07;

(ii) each share of Company Common Stock held in the treasury of the Company shall be canceled without any conversion thereof and no payment or distribution shall be made with respect thereto;

(iii) each share of Merger Sub Common Stock issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of common stock, par value $0.0001 per share, of the Surviving Corporation; and

(b) Prior to the Effective Time, the Company shall in a manner acceptable to GigCapital5 take such actions as are necessary to terminate each Company Option that is outstanding immediately prior to the Effective Time, whether vested or unvested, including by payment or in accordance with Section 16(c)(ii) of the Company Option Plan by providing fifteen (15) day notice to holders of the Company Options that if the business combination is consummated, based on the anticipated value of the Company Options, the Company Options shall be terminated without any conversion thereof and no payment or distribution shall be made, and the holder thereof shall cease to have any rights, with respect thereto. At or prior to the Effective Time, the parties and their boards, as applicable, shall adopt any resolutions and take any actions that are necessary to effectuate the treatment of the Company Options pursuant to the provisions of this Section 3.01(b).

(c) Effective as of the Effective Time, each outstanding In-the-Money Company Warrant that is not exercised and exchanged prior to the Effective Time shall automatically, without any action on the part of the holder thereof, in accordance with the provisions thereof (for the avoidance of doubt, as may be amended following the date of this Agreement with the written approval of GigCapital5), be converted into a warrant to acquire a number of shares of GigCapital5 Common Stock at an adjusted exercise price per share, in each case, as determined under this Section 3.01(c) (each such resulting warrant, an “Assumed Warrant”). Each Assumed Warrant shall be subject to the same terms and conditions as were applicable to such corresponding In-the-Money Company Warrant immediately prior to the Effective Time (including applicable vesting conditions), except to the extent such terms or conditions are rendered inoperative by the

Transactions. Accordingly, effective as of the Effective Time: (A) each such Assumed Warrant shall be exercisable solely for shares of GigCapital5 Common Stock; (B) the number of shares of GigCapital5 Common Stock subject to each Assumed Warrant shall be determined by multiplying the number of shares of Company Common Stock subject to such In-the-Money Company Warrant, as in effect immediately prior to the Effective Time, by the Per Share Merger Consideration, and rounding the resulting number down to the nearest whole number of shares of GigCapital5 Common Stock; (C) the per share exercise price for the GigCapital5 Common Stock issuable upon exercise of each Assumed Warrant shall be determined by dividing the per share exercise price for the shares of Company Common Stock subject to the In-the-Money Company Warrant, as in effect immediately prior to the Effective Time, by the Per Share Merger Consideration, and rounding the resulting exercise price up to the nearest whole cent; and (D) the holder of each In-the-Money Company Warrant outstanding as of immediately prior to the Effective Time shall be entitled to the contingent right to receive a portion of the Merger Consideration Earnout Shares, if, as and when payable in accordance with the provisions of Section 3.07. Effective as of the Effective Time, each Company Warrant (other than any In-the-Money Company Warrant) that is outstanding immediately prior to the Effective Time, whether vested or unvested, shall, in accordance with the provisions thereof (for the avoidance of doubt, as may be amended following the date of this Agreement with the written approval of GigCapital5), be canceled without any conversion thereof and no payment or distribution shall be made, and the holder thereof shall cease to have any rights, with respect thereto. At or prior to the Effective Time, the parties and their boards, as applicable, shall adopt any resolutions and take any actions that are necessary to effectuate the treatment of the Company Warrants (including by causing or entering into any amendments thereto) pursuant to the provisions of this Section 3.01(c).

(d) Notwithstanding anything to the contrary set forth in this Agreement, (i) the portion of the Aggregate Closing Merger Consideration issuable to any Person pursuant to Section 3.01(a)(i) and Section 3.01(c) shall be calculated on an aggregate basis with respect to all shares of Company Common Stock, and all In-the-Money Company Warrant Shares subject to In-the-Money Company Warrants, held of record by such person immediately prior to the Effective Time, and (ii) after such aggregation, any fractional share of GigCapital5 Common Stock that would otherwise be issuable to such person following such aggregation shall be rounded up to a whole share of GigCapital5 Common Stock.

SECTION 3.02 Delivery of Shares.

(a) On the Closing Date, GigCapital5 shall deposit, or shall cause to be deposited, with a bank or trust company that shall be designated by GigCapital5 and is reasonably satisfactory to the Company (the “Exchange Agent”), for the benefit of the Company Equity Securityholders, for exchange in accordance with this Article III, the number of shares of GigCapital5 Common Stock sufficient to deliver the aggregate Per Share Merger Consideration payable pursuant to this Agreement (such shares of GigCapital5 Common Stock, the Merger Consideration Earnout Shares and any dividends or distributions with respect thereto (pursuant to Section 3.02(c)), being hereinafter referred to as the “Exchange Fund”). GigCapital5 shall cause the Exchange Agent pursuant to irrevocable instructions, to pay the Per Share Merger Consideration out of the Exchange Fund in accordance with this Agreement. Except as contemplated by Section 3.02(c) and Section 3.07, the Exchange Fund shall not be used for any other purpose.

(b) As promptly as practicable after the effectiveness of the Registration Statement, GigCapital5 shall use its reasonable best efforts to cause the Exchange Agent to mail to each holder of Company Common Stock entitled to receive the Per Share Merger Consideration pursuant to Section 3.01: a letter of transmittal, which shall be in a form reasonably acceptable to GigCapital5 and the Company prior to the Closing (the “Letter of Transmittal”) and shall specify (i) that delivery shall be effected, and risk of loss and title to the certificates evidencing such shares of Company Common Stock (the “Certificates”) shall pass, only upon proper delivery of the Certificates to the Exchange Agent or confirmation of cancellation of such Certificates from the Company, (each, a “Transfer Agent Cancellation”); and (ii) instructions for use in effecting the surrender of the Certificates pursuant to the Letter of Transmittal. Within two (2) Business Days (but in no event prior to the Effective Time) after the surrender to the Exchange Agent of all

Certificates held by such holder for cancellation (or a Transfer Agent Cancellation), together with a Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto and such other documents as may be required pursuant to such instructions, the holder of such Certificates shall be entitled to receive in exchange therefore, and QTI Holdings shall cause the Exchange Agent to deliver, the Per Share Merger Consideration with respect thereto in accordance with the provisions of Section 3.01, and the Certificate so surrendered shall forthwith be cancelled. Until surrendered as contemplated by this Section 3.02, each Certificate entitled to receive the Per Share Merger Consideration in accordance with Section 3.01(a)(i) shall be deemed at all times after the Effective Time to represent only (A) the right to receive upon such surrender the Per Share Merger Consideration that such holder is entitled to receive in accordance with the provisions of Section 3.01(a)(i) and (B) the contingent right to receive a portion of the Merger Consideration Earnout Shares, if, as and when payable in accordance with the provisions of Section 3.07.

(c) No dividends or other distributions declared or made after the Effective Time with respect to the GigCapital5 Common Stock with a record date after the Effective Time shall be paid from the Exchange Fund to the holder of any unsurrendered Certificate with respect to the shares of GigCapital5 Common Stock represented thereby until the holder of such Certificate shall surrender such Certificate in accordance with Section 3.02(b). Subject to the effect of escheat, Tax or other applicable Laws, following surrender of any such Certificate, QTI Holdings shall pay or cause to be paid to the holder of the certificates representing shares of GigCapital5 Common Stock issued in exchange therefore, without interest, (i) promptly, but in any event within five (5) Business Days of such surrender, the amount of dividends or other distributions with a record date after the Effective Time and theretofore paid with respect to such shares of GigCapital5 Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date after the Effective Time but prior to surrender and a payment date occurring after surrender, payable with respect to such shares of GigCapital5 Common Stock.

(d) The Per Share Merger Consideration and the Merger Consideration Earnout Shares payable upon conversion of the Company Equity Securities in accordance with the terms hereof shall be deemed to have been paid and issued in full satisfaction of all rights pertaining to such Company Equity Securities.

(e) The Per Share Merger Consideration shall be adjusted to reflect appropriately the effect of any stock split, reverse stock split, stock dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to GigCapital5 Common Stock occurring on or after the date hereof and prior to the Effective Time.

(f) Except as set forth in Section 3.07 hereto, any portion of the Exchange Fund that remains undistributed to the Company Equity Securityholders for one year after the Effective Time shall be delivered to QTI Holdings, upon demand, and any Company Equity Securityholders who have not theretofore complied with this Section 3.02 shall thereafter look only to QTI Holdings for the Per Share Merger Consideration. Any portion of the Exchange Fund remaining unclaimed by the applicable Company Equity Securityholders as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any government entity shall, to the extent permitted by applicable law, become the property of QTI Holdings free and clear of any claims or interest of any person previously entitled thereto.

(g) None of the Exchange Agent, QTI Holdings or the Surviving Corporation shall be liable to any Company Equity Securityholder for any such Company Equity Securities (or dividends or distributions with respect thereto) or cash delivered to a public official pursuant to any abandoned property, escheat or similar Law in accordance with Section 3.02.

(h) Each of the Surviving Corporation and QTI Holdings shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to a person such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld and timely remitted to the appropriate Governmental Authority by the Surviving Corporation or QTI Holdings, as the case may be, such withheld

amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding was made by the Surviving Corporation or QTI Holdings, as the case may be. If the Surviving Corporation or QTI Holdings intends to withhold any Taxes from any amounts payable to holders of equity interests in the Company (other than with respect to any withholding) on amounts treated as compensation for applicable Tax purposes, QTI Holdings shall use reasonable best efforts to provide prior notice of such withholding to the Company as soon as reasonably practicable after it determines withholding is required. The Surviving Corporation, QTI Holdings and any Company Equity Securityholder, as applicable, shall reasonably cooperate to reduce or seek an exemption from any withholding, including providing the Person in respect of which such deduction and withholding was made with a reasonable opportunity to provide forms or other evidence that would exempt such amounts from withholding.

(i) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate, the Per Share Merger Consideration that such holder is otherwise entitled to receive pursuant to, and in accordance with, the provisions of Section 3.01(a)(i).

SECTION 3.03 Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of Company Common Stock thereafter on the records of the Company. From and after the Effective Time, the holders of Certificates representing Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Company Common Stock, except as otherwise provided in this Agreement or by Law. On or after the Effective Time, any Certificates presented to the Exchange Agent or QTI Holdings for any reason shall be converted into (a) the Per Share Merger Consideration in accordance with the provisions of Section 3.01(a)(i) and (b) the contingent right to receive a portion of the Merger Consideration Earnout Shares if, as and when payable in accordance with the provisions of Section 3.07.

SECTION 3.04 Payment of Expenses.

(a) No sooner than five (5) or later than two (2) Business Days prior to the Closing Date, the Company shall provide to GigCapital5 a written report setting forth a list of all of the following fees, expenses and disbursements incurred by or on behalf of the Company in connection with the preparation, negotiation and execution of this Agreement and the consummation of the transactions contemplated hereby (together with paid invoices or wire transfer confirmation receipts), including such fees and expenses that have been (x) paid or will be paid prior to the close of business on the Business Day immediately preceding the Closing (collectively, the “Paid Company Transaction Expenses”) or (y) incurred and expected to remain unpaid as of the close of business on the Business Day immediately preceding the Closing Date (collectively, the “Unpaid Company Transaction Expenses” and, together with the Paid Company Transaction Expenses, the “Company Transaction Expenses”): (i) the amount of expenses paid by the Company pursuant to the provisions of Section 9.03; (ii) the fees and disbursements of outside legal counsel to the Company incurred in connection with the Transactions; (iii) the fees, costs and expenses associated with the Tail Policies; and (iv) the fees, costs, commissions and expenses of any other agents, advisors, consultants, experts, financial advisors, lenders, brokers and other service providers engaged by or on behalf of, or otherwise entitled to payments or other compensation from, the Company in connection with the Transactions. On the Closing Date following the Closing, QTI Holdings shall pay or cause to be paid by wire transfer of immediately available funds all such Unpaid Company Transaction Expenses (other than any such Unpaid Company Transaction Expenses to be satisfied by the issuance of shares of GigCapital5 Common Stock pursuant to the provisions of Section 3.04(d) and Section 3.04(g)). For the avoidance of doubt, the Company Transaction Expenses shall not include any fees and expenses incurred by the Company’s stockholders (except to the extent incurred on behalf, and for the account, of the Company).

(b) No sooner than five (5) or later than two (2) Business Days prior to the Closing Date, GigCapital5 shall provide to the Company a written report setting forth: (i) the amount of expenses paid by GigCapital5

pursuant to the provisions of Section 9.03 (the “Paid GigCapital5 Transaction Expenses”); (ii) a list of all the fees and disbursements of outside legal counsel, agents, advisors, consultants, experts, financial advisors, lenders, brokers and other service providers engaged by or on behalf of, or otherwise entitled to payments or other compensation from, GigCapital5 or Merger Sub in connection with the Transactions or otherwise in connection with GigCapital5’s operations (together with written invoices and wire transfer instructions for the payment thereof); and (iii) a list of all costs and expenses payable to the R&W Insurance Provider in connection with the transactions contemplated herein (the fees, costs, expenses and disbursements described in the foregoing clauses (ii) and (iii), collectively, the “Unpaid GigCapital5 Transaction Expenses” and, together with the Paid GigCapital5 Transaction Expenses, the “GigCapital5 Transaction Expenses”). On the Closing Date following the Closing, QTI Holdings shall pay or cause to be paid by wire transfer of immediately available funds all such Unpaid GigCapital5 Transaction Expenses (other than any such Unpaid GigCapital5 Transaction Expenses to be satisfied by the issuance of shares of GigCapital5 Common Stock pursuant to the provisions of Section 3.04(e)).

(c) QTI Holdings shall not pay or cause to be paid any Unpaid GigCapital5 Transaction Expenses or Unpaid Company Transaction Expenses other than in accordance with this Section 3.04.

(d) Notwithstanding anything to the contrary set forth in this Agreement, if the Unpaid Company Transaction Expenses would exceed the Company Transaction Expenses Cap, the Company shall use its reasonable best efforts to cause its agents, advisors, consultants, experts, financial advisors and other service providers (other than outside legal counsel, certified public accountants, insurance companies and brokers, trust and transfer agents and other similarly situated service providers) who are or will be owed Unpaid Company Transaction Expenses to agree in writing to accept payment of such excess (or any applicable portion thereof) in the form of shares of GigCapital5 Common Stock, in lieu of cash, up to an aggregate number of shares of GigCapital5 Common Stock equal to the Aggregate Excess Company Transaction Expenses Shares, to be issued by GigCapital5 to such service providers of the Company at the Closing on terms and conditions approved in writing by GigCapital5 (such approval not to be unreasonably withheld, conditioned or delayed). Subject to the foregoing, GigCapital5 shall, at the Closing, issue such shares of GigCapital5 Common Stock to such service providers of the Company in accordance with such approved terms and conditions.

(e) Notwithstanding anything to the contrary set forth in this Agreement, if the Unpaid GigCapital5 Transaction Expenses would exceed the GigCapital5 Transaction Expenses Cap, GigCapital5 shall use its reasonable best efforts to cause its agents, advisors, consultants, experts, financial advisors and other service providers (other than outside legal counsel, certified public accountants, insurance companies and brokers, trust and transfer agents and other similarly situated service providers) who are or will be owed Unpaid GigCapital5 Transaction Expenses to agree in writing to accept payment of such excess (or any applicable portion thereof) in the form of shares of GigCapital5 Common Stock, in lieu of cash, up to an aggregate number of shares of GigCapital5 Common Stock equal to the Aggregate Excess GigCapital5 Transaction Expenses Shares, to be issued by GigCapital5 to such service providers of GigCapital5 at the Closing on terms and conditions approved in writing by the Company (such approval not to be unreasonably withheld, conditioned or delayed). Subject to the foregoing, GigCapital5 shall, at the Closing, issue such shares of GigCapital5 Common Stock to such service providers of GigCapital5 in accordance with such approved terms and conditions.

(f) If the Unpaid GigCapital5 Transaction Expenses exceed the Unpaid GigCapital5 Transaction Expenses Cap, GigCapital5 shall cause the Sponsor, at the Closing, to irrevocably forfeit and transfer to GigCapital5 a number of shares of GigCapital5 Common Stock equal to the Aggregate Excess GigCapital5 Transaction Expenses Shares, and thereafter the Sponsor shall have no further right or interest in such shares of GigCapital5 Common Stock, which shall remain in treasury at GigCapital5 until otherwise disposed of by GigCapital5 in its sole discretion.

(g) Notwithstanding anything to the contrary set forth in this Agreement, the Unpaid Company Transaction Expenses set forth on Schedule 3.04(g) shall be settled in shares of GigCapital5 Common Stock

issued to the applicable individual service providers of the Company at the Closing on the terms and conditions set forth in the written agreements between the Company and such service providers, together with any amendments thereto as may be reasonably required by GigCapital5. Subject to the foregoing, GigCapital5 shall, at the Closing, issue such shares of GigCapital5 Common Stock to such service providers of the Company in accordance with such terms and conditions, as may be amended. For the avoidance of doubt, each such share of GigCapital5 Common Stock issued pursuant to this Section 3.04(g) shall be treated as $10.00 of Unpaid Company Transaction Expenses.

SECTION 3.05 Appraisal Rights.

(a) Notwithstanding any provision of this Agreement to the contrary and to the extent available under the DGCL, shares of Company Common Stock that are outstanding immediately prior to the Effective Time and that are held by stockholders of the Company who shall have neither voted in favor of the Merger nor consented thereto in writing and who shall have demanded properly in writing appraisal for such Company Common Stock in accordance with Section 262 of the DGCL and otherwise complied with all of the provisions of the DGCL relevant to the exercise and perfection of dissenters’ rights shall not be converted into, and such stockholders shall have no right to receive, the Per Share Merger Consideration or the contingent right to receive any portion of the Merger Consideration Earnout Shares, unless and until such stockholder fails to perfect or withdraws or otherwise loses his, her or its right to appraisal and payment under the DGCL. Any stockholder of the Company who fails to perfect or who effectively withdraws or otherwise loses his, her or its rights to appraisal of such shares of Company Common Stock under Section 262 of the DGCL shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive (i) the Per Share Merger Consideration, without any interest thereon, upon surrender, in the manner provided in Section 3.01(a)(i), of the Certificate or Certificates that formerly evidenced such shares of Company Common Stock, and a portion of the Merger Consideration Earnout Shares if, as and when payable in accordance with the provisions of Section 3.07.

(f) by written notice by GigCapital5 to the Company upon a breach of any representation, warranty, covenant or agreement on the part of the Company set forth in this Agreement, or if any representation or warranty of the Company shall have become untrue, in either case such that the conditions set forth in Sections 8.02(a) and 8.02(b) would not be satisfied (“Terminating Company Breach”); provided that GigCapital5 has not waived such Terminating Company Breach and GigCapital5 and Merger Sub are not then in material breach of their representations, warranties, covenants or agreements in this Agreement; provided further that, if such Terminating Company Breach is curable by the Company, GigCapital5 may not terminate this Agreement under this Section 9.01(f) for so long as the Company continues to exercise its reasonable efforts to cure such breach, unless such breach is not cured within thirty (30) days after notice of such breach is provided by GigCapital5 to the Company; or

(g) by written notice by the Company to GigCapital5 upon a breach of any representation, warranty, covenant or agreement on the part of GigCapital5 or Merger Sub set forth in this Agreement, or if any representation or warranty of GigCapital5 or Merger Sub shall have become untrue, in either case such that the conditions set forth in Sections 8.03(a) and 8.03(b) would not be satisfied (“Terminating GigCapital5 Breach”); provided that the Company has not waived such Terminating GigCapital5 Breach and the Company is not then in material breach of their representations, warranties, covenants or agreements in this Agreement; provided, however, that, if such Terminating GigCapital5 Breach is curable by GigCapital5 and Merger Sub, the Company may not terminate this Agreement under this Section 9.01(g) for so long as GigCapital5 and Merger Sub continue to exercise their reasonable efforts to cure such breach, unless such breach is not cured within thirty (30) days after notice of such breach is provided by the Company to GigCapital5; or

(h) by written notice by either GigCapital5 or the Company to the other party, if the condition set forth in Section 8.01(h) has not been satisfied.

SECTION 9.02 Effect of Termination.

Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the Transactions be consummated as originally contemplated to the fullest extent possible.

This Agreement and the Ancillary Agreements constitute the entire agreement among the parties with respect to the subject matter hereof and supersede, except as set forth in Section 7.04(b), all prior agreements, and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof, except for the Confidentiality Agreement.

Each of the parties further agrees that notice as provided herein shall constitute sufficient service of process and the parties further waive any argument that such service is insufficient.

INTO THIS AGREEMENT AND THE TRANSACTIONS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.07.

SECTION 10.08 Headings. The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.

RECITALS

WHEREAS, concurrently herewith, the Company, QTI Merger Sub, Inc., a Delaware corporation (“Merger Sub”), and GigCapital5 are entering into a Business Combination Agreement (as amended, supplemented, restated or otherwise modified from time to time, the “BCA”), pursuant to which (and subject to the terms and conditions set forth therein) Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of GigCapital5;

WHEREAS, capitalized terms used but not otherwise defined in this Agreement shall have the meanings ascribed to them in the BCA;

WHEREAS, the Sponsor is currently the record owner of 6,530,000 shares of GigCapital5 Common Stock (the “Sponsor Shares”); and

WHEREAS, as a condition and inducement to the willingness of GigCapital5 and the Company to enter into the BCA, GigCapital5, the Company and the Sponsor are entering into this Agreement.

AGREEMENT

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the Sponsor, GigCapital5 and the Company hereby agree as follows:

1. Voting Agreement. The Sponsor agrees that, at the GigCapital5 Stockholders’ Meeting, at any other meeting of the stockholders of GigCapital5 (whether annual or special and whether or not an adjourned or postponed meeting, however called and including any adjournment or postponement thereof) and in connection with any written consent of the stockholders of GigCapital5, the Sponsor shall:

a. when such meeting is held, appear at such meeting or otherwise cause the Sponsor Shares to be counted as present thereat for the purpose of establishing a quorum;

b. vote (or execute and return an action by written consent), or cause to be voted at such meeting (or validly execute and return and cause such consent to be granted with respect to), all of the Sponsor Shares (i) in favor of the approval and adoption of the BCA and approval of the Merger and all other transactions contemplated by the BCA and (ii) against any action, agreement or transaction or proposal that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of GigCapital5 under the BCA or that would reasonably be expected to result in the failure of the Merger from being consummated and (iii) in favor of each of the proposals and any other matters necessary or reasonably requested by GigCapital5 for consummation of the Merger and the other transactions contemplated by the BCA; and

c. vote (or execute and return an action by written consent), or cause to be voted at such meeting (or validly execute and return and cause such consent to be granted with respect to), all of the Sponsor Shares against

(i) any Business Combination Proposal other than with the Company and (ii) any other action that would reasonably be expected to (x) materially impede, interfere with, delay, postpone or adversely affect the Merger or any of the other transactions contemplated by the BCA, or (y) result in a breach of any covenant, representation or warranty or other obligation or agreement of the Sponsor contained in this Agreement.

2. Transfer of Shares. Except as otherwise contemplated by the BCA or this Agreement, the Sponsor agrees that it shall not, directly or indirectly, (a) sell, assign, transfer (including by operation of law), create any lien or pledge, dispose of or otherwise encumber any of the Sponsor Shares or otherwise agree to do any of the foregoing, (b) deposit any Sponsor Shares into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect thereto that is inconsistent with this Agreement or (c) enter into any contract, option or other arrangement or undertaking requiring the direct acquisition or sale, assignment, transfer or other disposition of any Sponsor Shares. Without limiting the foregoing, and for the avoidance of doubt, the Sponsor agrees to comply, during the term of this Agreement, with the provisions of section 9 of that certain letter agreement, dated September 23, 2021, by and among GigCapital5, Sponsor, Xxxxx Fargo Securities, LLC and Xxxxxxx Xxxxx & Company, L.L.C.

3. No Solicitation of Transactions.

Sponsor shall, and shall cause its affiliates and Representatives to, immediately cease any and all existing discussions or negotiations with any person (other than with the Company, its stockholders and their respective affiliates and Representatives) conducted prior to the date hereof with respect to, or which is reasonably likely to give rise to or result in, a Business Combination Proposal. If the Sponsor receives any inquiry or proposal with respect to a Business Combination Proposal, then Sponsor shall promptly (and in no event later than twenty-four (24) hours after the Sponsor becomes aware of such inquiry or proposal) notify such person in writing that GigCapital5 is subject to an exclusivity agreement with respect to the Merger that prohibits Sponsor from considering such inquiry or proposal.

4. Representations and Warranties of the Sponsor. The Sponsor hereby represents and warrants to GigCapital5 and the Company as follows:

a. The Sponsor is the only record and a beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act) of, and has good, valid and marketable title to, the Sponsor Shares, free and clear of Liens other than as created by this Agreement or Sponsor’s organizational documents or the organizational documents of GigCapital5 (including, without limitation, for the purposes hereof, any agreement between or among stockholders of GigCapital5).

c. The Sponsor (i) is a legal entity duly organized, validly existing and, to the extent such concept is applicable, in good standing under the Laws of the jurisdiction of its organization and (ii) has all requisite limited liability company or other power and authority and has taken all limited liability company or other action necessary in order to, execute, deliver and perform its obligations under this Agreement and to consummate the transactions contemplated hereby.

e. The execution, delivery and performance of this Agreement by the Sponsor does not, and the consummation of the transactions contemplated hereby or the Merger and the other transactions contemplated by the BCA will not, constitute or result in (i) a breach or violation of, or a default under, the limited liability company agreement or similar governing documents of the Sponsor, (ii) with or without notice, lapse of time or both, a breach or violation of, a termination (or right of termination) of or a default under, the loss of any benefit under, the creation, modification or acceleration of any obligations under or the creation of a Lien on any of the properties, rights or assets of the Sponsor pursuant to any contract binding upon the Sponsor or, assuming (solely with respect to performance of this Agreement and the transactions contemplated hereby), compliance with the matters referred to in Section 1, under any applicable Law to which the Sponsor is subject or (iii) any change in the rights or obligations of any party under any contract legally binding upon the Sponsor, except, in the case of clause (ii) or (iii) directly above, for any such breach, violation, termination, default, creation, acceleration or change that would not, individually or in the aggregate, reasonably be expected to prevent or materially delay or impair the Sponsor’s ability to perform its obligations hereunder or to consummate the transactions contemplated hereby, the consummation of the Merger or the other transactions contemplated by the BCA.

f. As of the date of this Agreement, there is no action, proceeding or investigation pending against the Sponsor or, to the knowledge of the Sponsor, threatened against the Sponsor that questions the beneficial or record ownership of the Sponsor Shares, the validity of this Agreement or the performance by the Sponsor of its obligations under this Agreement.

hereunder. Any agreement on the part of a party hereto to any such waiver shall be valid only if set forth in a written instrument executed and delivered by such party.

RECITALS

WHEREAS, GigCapital5, QTI Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of GigCapital5 (“Merger Sub”), and the Company have negotiated a Business Combination Agreement in the form attached hereto as Exhibit B (the “BCA”; terms used but not defined in this Agreement shall have the meanings ascribed to them in the BCA), which provides, among other things, that, upon the terms and subject to the conditions thereof, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of GigCapital5; and

WHEREAS, as of the date hereof, each Stockholder owns of record the number of shares of Company Common Stock and Company Preferred Stock as set forth opposite such Stockholder’s name on Exhibit A hereto (all such shares of Company Common Stock and Company Preferred Stock and any shares of Company Common Stock and Company Preferred Stock of which ownership of record or the power to vote is hereafter acquired by the Stockholders prior to the termination of this Agreement being referred to herein as the “Shares”).

AGREEMENT

NOW, THEREFORE, in consideration of the foregoing and of the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

1. BCA Approved; Agreement to Vote. Each Stockholder, with respect to such Stockholder’s Shares, severally and not jointly, hereby agrees to vote, at any meeting of the Stockholders of the Company, and in any action by written consent of the Stockholders of the Company (which written consent shall be delivered promptly, and in any event within forty eight (48) hours, after the Company requests such delivery), all of the Shares held by such Stockholder at such time in favor of the approval and adoption of the BCA and approval of the Merger and all other transactions contemplated by the BCA, provided in all cases that no changes have been made in the BCA or in the Merger or related transactions or ancillary agreements under the BCA that are material to one or more of the Stockholders. Provided no changes are made in the BCA or in the Merger or related transactions or ancillary agreements under the BCA that are material to one or more of the Stockholders, each Stockholder, severally and not jointly, hereby agrees to vote at any meeting of the Stockholders of the Company, and to act by written consent of Company Stockholders, against any action, agreement, transaction or proposal that would cause a material breach of any covenant, representation, warranty or other obligation or agreement of the Company under the BCA or that would reasonably be expected to prevent the Merger from being consummated. Each Stockholder acknowledges receipt and review of a copy of the BCA.

2. Termination of Stockholder Rights. Subject to consummation of the Closing pursuant to the BCA, each Stockholder, severally and not jointly, hereby agrees that, if applicable to such Stockholder, any rights under Article VII (Transfer of Shares and Admission of New Stockholders) and Article VIII (Tag Along Rights) of the Company’s Bylaws, as amended, and any rights under any letter agreement providing for redemption rights, put rights, purchase rights or similar rights not generally available to Stockholders of the Company (the “Terminating Rights”) between such Stockholder and the Company, shall terminate (and such Stockholder, without any further action, shall automatically and irrevocably release and waive any claim such Stockholder may have thereunder)

immediately prior to the Closing under the BCA, and prior thereto such Stockholder shall not exercise such rights in any manner inconsistent with the BCA or otherwise reasonably likely to interfere with, delay, impede, frustrate or prevent the consummation of the Merger. For the avoidance of doubt, the Terminating Rights shall exclude any rights such Stockholder may have that relate to any commercial or employment agreements or arrangements between such Stockholder and the Company or any subsidiary of the Company, which shall survive in accordance with their terms.

3. Transfer of Shares. Each Stockholder, severally and not jointly, agrees that he, she or it shall not, directly or indirectly, (a) sell, assign, transfer (including by operation of law), create any lien or pledge, dispose of or otherwise encumber any of the Shares or otherwise agree to do any of the foregoing, except for a sale, assignment or transfer pursuant to the BCA or to another Stockholder of the Company that is a party to this Agreement and bound by the terms and obligations hereof, (b) deposit any Shares into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect thereto that is inconsistent with this Agreement or (c) enter into any contract, option or other arrangement or undertaking with respect to the direct acquisition or sale, assignment, transfer or other disposition of any Shares, except as set forth in the BCA or this Agreement; provided, that the foregoing shall not prohibit the transfer of the Shares to an affiliate of Stockholder, but only if such affiliate of such Stockholder shall execute this Agreement or a joinder agreeing to become a party to this Agreement.

4. No Solicitation of Transactions. Each of the Stockholders, severally and not jointly, agrees not to directly or indirectly, through any officer, director, representative, agent or otherwise, (a) solicit, initiate or knowingly encourage (including by furnishing information) the submission of, or participate in any discussions or negotiations regarding, any transaction in violation of the BCA or (b) participate in any discussions or negotiations regarding, or furnish to any person or other entity or “group” within the meaning of Section 13(d) of the Exchange Act, any information with the intent to, or otherwise cooperate in any way with respect to, or knowingly assist, participate in, facilitate or encourage, any unsolicited proposal that constitutes, or may reasonably be expected to lead to, an Alternative Transaction in violation of the BCA. Each Stockholder shall, and shall direct his, her or its representatives and agents to, immediately cease and cause to be terminated any discussions or negotiations with any parties that may be ongoing with respect to any Alternative Transaction (other than the transactions contemplated by the BCA) to the extent required by the BCA. If any Stockholder receives any inquiry or proposal with respect to an Alternative Transaction, then such Stockholder shall promptly (and in no event later than twenty-four (24) hours after such Stockholder becomes aware of such inquiry or proposal) notify such person in writing that the Company is subject to an exclusivity agreement with respect to the sale of the Company that prohibits such Stockholder from considering such inquiry or proposal.

5. Representations and Warranties. Each Stockholder, severally and not jointly, represents and warrants to GigCapital5 as follows:

(a) The execution, delivery and performance by such Stockholder of this Agreement and the consummation by such Stockholder of the transactions contemplated hereby do not and will not (i) conflict with or violate any statute, law, ordinance, regulation, rule, code, executive order, injunction, judgment, decree or other order applicable to such Stockholder, (ii) require any consent, approval or authorization of, declaration, filing or registration with, or notice to, any person or entity, (iii) result in the creation of any encumbrance on any Shares (other than under this Agreement, the BCA and the agreements contemplated by the BCA) or (iv) if such Stockholder is an entity, conflict with or result in a breach of or constitute a default under any provision of such Stockholder’s governing documents.

(b) As of the date of this Agreement, such Stockholder owns exclusively of record and has good and valid title to the Shares set forth opposite the Stockholder’s name on Exhibit A free and clear of any security interest, lien, claim, pledge, proxy, option, right of first refusal, agreement, voting restriction, limitation on disposition, charge, adverse claim of ownership or use or other encumbrance of any kind and has the sole power to vote and the right, power and authority to sell, transfer and deliver such Shares, other than pursuant and subject to: (i) this Agreement, (ii) applicable securities laws, and (iii) the Company’s certificate of incorporation and bylaws. Such Stockholder is not the registered owner of any Shares other than those set forth on Exhibit A.

(c) Such Stockholder has the power, authority and capacity to execute, deliver and perform this Agreement and that this Agreement has been duly authorized, executed and delivered by such Stockholder. No person not a signatory to this Agreement (or such signatory’s spouse for purposes of applicable community property laws) has a beneficial interest in or a right to acquire or vote any of the Shares (other than, if Stockholder is trust, the beneficiary(ies) thereof).

6. Termination. This Agreement and the obligations and liabilities of the Stockholders under this Agreement shall automatically terminate upon the earliest of (a) the Effective Time; (b) the termination of the BCA in accordance with its terms, (c) the effective date of a written agreement of the parties hereto terminating this Agreement and (d) any material breach by GigCapital5 of the BCA that is not fully cured within the time permitted by the BCA.

(h) This Agreement may be executed and delivered (including by facsimile or portable document format (pdf) transmission) in counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

(i) At the request of GigCapital5, in the case of any Stockholder, or at the request of any Stockholder, in the case of GigCapital5, and without further consideration, each party shall execute and deliver or cause to be executed and delivered such additional documents and instruments and take such further action as may be reasonably necessary to implement the provisions of this Agreement.

Subject to the provisions of Section 2.1.4 and Section 2.4 hereof, at any time and from time to time on or after the Closing Date, the Holders holding at least a majority in interest of the then-outstanding number of Registrable Securities held by all the Holders (such Holders, the “Demanding Holders”), may make a written demand for Registration under the Securities Act of all or part of their Registrable Securities, which written demand shall describe the amount and type of securities to be included in such Registration and the intended method(s) of distribution thereof (such written demand a “Demand Registration”). The Company shall, within ten (10) days of the Company’s receipt of the Demand Registration, notify, in writing, all other Holders of Registrable Securities of such demand, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in the Demand Registration (each such Holder that includes all or a portion of such Holder’s Registrable Securities in such Registration, a “Requesting Holder”) shall so notify the Company, in writing, within five (5) days after the receipt by the Holder of the notice from the Company. Upon receipt by the Company of any such written notification from a Requesting Holder(s) to the Company, such Requesting Holder(s) shall be entitled to have their Registrable Securities included in a Registration pursuant to a Demand Registration and the Company shall effect, as soon thereafter as practicable, but not more than forty five (45) days immediately after the Company’s receipt of the Demand Registration, the Registration of all Registrable Securities requested by the Demanding Holders and Requesting Holders pursuant to such Demand Registration. Under no circumstances shall the Company be obligated to effect more than an aggregate of three (3) Registrations pursuant to a Demand Registration under this Section 2.1.1 initiated by Holders; provided, however, that an Underwritten Offering pursuant to a Demand Registration shall not be counted for such purposes unless a Registration Statement that may be available at such time has become effective and all of the Registrable Securities requested by the Demanding Holders to be registered on behalf of the Demanding Holders in such Registration Statement have been sold, in accordance with Section 3.1 of this Agreement.

2.1.2 Effective Registration. Notwithstanding the provisions of Section 2.1.1 above or any other part of this Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement filed with the Commission with respect to such Demand Registration has been declared effective by the Commission and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, that if, after such Registration Statement has been declared effective, the offering of Registrable Securities pursuant to a Demand Registration is interfered with by any stop order or injunction of the Commission or any other governmental agency or court, the Registration Statement with respect to such Demand Registration will be deemed not to have been declared effective, unless and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders initiating such Demand Registration thereafter affirmatively elect to continue with such Registration and accordingly notify the Company in writing of such election, which notice shall be received by the Company not later than five (5) days after the removal of any such stop order or injunction; provided, further, that the Company shall not be obligated to file a second Registration Statement until a Registration Statement that has been previously filed pursuant to a Demand Registration becomes effective or is terminated.

2.1.3 Underwritten Offering. Subject to the provisions of Section 2.1.4 and Section 2.4 hereof, if a majority-in-interest of the Demanding Holders so advise the Company as part of their Demand Registration that the offering of Registrable Securities pursuant thereto shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or Requesting Holder (if any) to include its Registrable Securities in such Registration shall be conditioned upon such Holder’s participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten Offering to the extent provided herein. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this Section 2.1.3 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by a majority-in-interest of the Demanding Holders initiating the Demand Registration.

2.1.4 Reduction of Underwritten Offering. If the managing Underwriter(s) for a Demand Registration that is to be an Underwritten Offering, in good faith, advises the Company, the Demanding Holders and the Requesting Holders in writing that the dollar amount or number of Registrable Securities which the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other shares of Common Stock or other equity securities which the Company desires to sell and the shares of Common Stock, if any, as to which a Registration has been requested pursuant to separate written contractual piggyback registration rights held by other stockholders of the Company who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such Underwritten Offering (such maximum dollar amount or maximum number of securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and the Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the Demanding Holders and Requesting Holders have requested be included in such Underwritten Registration (such proportion is referred to herein as “Pro Rata”, provided, however, that such Pro Rata proportion shall not include any unvested Earnout Shares)) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the Registrable Securities of Holders (Pro Rata, based on the respective number of Registrable Securities that each Holder has so requested exercising their rights to register their Registrable Securities pursuant to Section 2.2.1 hereof), that can be sold without exceeding the Maximum Number of Securities; (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (iv) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i), (ii) and (iii), the Common Stock or other equity securities of other persons or entities that the Company is obligated to register in a Registration pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities.

2.1.5 Demand Registration Withdrawal. Any Demanding Holder shall have the right to withdraw from a Registration pursuant to such Demand Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter(s) (if any) of their intention to withdraw from such Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to the Registration of their Registrable Securities pursuant to such Demand Registration. Notwithstanding anything to the contrary in this Agreement, if with respect to a Demand Registration, a majority-in-interest of the Demanding Holders initiating a Demand Registration so withdraw from a Registration pursuant to such Demand Registration, such Registration shall not count as a Demand Registration provided for in Section 2.1.1 and the Company shall be responsible for the Registration Expenses incurred in connection with a Registration pursuant to a Demand Registration prior to its withdrawal under this Section 2.1.5.

Section 2.2 Piggyback Registration.

2.2.1 Piggyback Rights. If, at any time on or after the Closing Date, the Company proposes to file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into, equity securities, for its own account or for the account of stockholders of the Company (or by the Company and by stockholders of the Company including, without limitation, pursuant to Section 2.1), other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall (x) give written notice of such proposed filing to all of the Holders of Registrable Securities as soon as practicable but in no event less than ten (10) days before the anticipated filing date, which notice shall describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, of the offering, and (y) offer to all of the Holders of Registrable Securities in

such notice the opportunity to register the sale of such number of shares of Registrable Securities as such Holders may request in writing within five (5) days following receipt of such notice (a “Piggyback Registration”). The Company shall, in good faith, cause such Registrable Securities to be included in such Registration and shall use its best efforts to cause the managing Underwriter(s) of a proposed Underwritten Offering to permit the Registrable Securities requested to be included in such Piggyback Registration on the same terms and conditions as any similar securities of the Company and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All holders of Registrable Securities proposing to distribute their Registrable Securities through a Piggyback Registration that involves an Underwriter(s) shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Piggyback Registration.

2.2.2 Reduction of Piggyback Registration. If the managing Underwriter(s) for a Piggyback Registration that is to be an Underwritten Offering, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of securities which the Company desires to sell, taken together with (i) the Common Stock or other equity securities, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which Registration has been requested under this Section 2.2, and (iii) the Common Stock or other equity securities, if any, as to which Registration has been requested pursuant to separate written contractual piggyback registration rights of other stockholders of the Company, exceeds the Maximum Number of Securities, then:

(i) If the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (A) first, the Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggyback registration rights of other stockholders of the Company that pre-dates this Agreement, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Section 2.2.1 hereof, Pro Rata, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggyback registration rights of other stockholders of the Company not otherwise covered above, which can be sold without exceeding the Maximum Number of Securities; and

(ii) If the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Company shall include in any such Registration (A) first, the Common Stock or other equity securities, if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Section 2.2.1, Pro Rata based on the number of Registrable Securities that each Holder has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the Holders have requested to be included in such Underwritten Registration, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the Common Stock or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number of Securities.

2.2.3 Piggyback Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter(s) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration. The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this Section 2.2.3.

2.2.4 Unlimited Piggyback Registration Rights. For purposes of clarity, any Registration effected pursuant to Section 2.2 hereof shall not be counted as a Registration pursuant to a Demand Registration effected under Section 2.1 hereof.

Section 2.3 Registration on Form S-3. The Holders of Registrable Securities may at any time, and from time to time, request in writing that the Company, pursuant to Rule 415 under the Securities Act (or any successor rule promulgated thereafter by the Commission), register the resale of any or all of their Registrable Securities on Form S-3 or any similar short-form registration statement that may be available at such time (“Form S-3”); provided, that the Company shall not be obligated to effect such request through an Underwritten Offering. Within five (5) days of the Company’s receipt of a written request from a Holder or Holders of Registrable Securities for a Registration on Form S-3, the Company shall promptly give written notice of the proposed Registration on Form S-3 to all other Holders of Registrable Securities, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in such Registration on Form S-3 shall so notify the Company, in writing, within ten (10) days after the receipt by the Holder of the notice from the Company. As soon as practicable thereafter, but not more than twelve (12) days after the Company’s initial receipt of such written request for a Registration on Form S-3, the Company shall register all or such portion of such Holder’s Registrable Securities as are specified in such written request, together with all or such portion of Registrable Securities of any other Holder or Holders joining in such request as are specified in the written notification given by such Holder or Holders; provided, that the Company shall not be obligated to effect any such Registration pursuant to this Section 2.3 if (i) a Form S-3 is not available for such offering; or (ii) the Holders of Registrable Securities, together with the Holders of any other equity securities of the Company entitled to inclusion in such Registration, propose to sell the Registrable Securities and such other equity securities (if any) at any aggregate price to the public of less than $5,000,000. Registrations effected pursuant to this Section 2.3 shall not be counted as Demand Registrations effected pursuant to Section 2.1.

Section 2.4 Restrictions on Registration Rights. If (A) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration and provided that the Company has delivered written notice to the Holders prior to receipt of a Demand Registration pursuant to Section 2.1.1 and it continues to actively employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become effective; (B) the Holders have requested an Underwritten Registration and the Company and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer; or (C) in the good faith judgment of the Board such Registration would be seriously detrimental to the Company and the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to such Holders a certificate signed by the Chairman of the Board stating that in the good faith judgment of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is therefore essential to defer the filing of such Registration Statement. In such event, the Company shall have the right to defer such filing for a period of not more than thirty (30) days; provided, that the Company may not defer its obligation in this manner more than once in any 12-month period.

3.1.13 on the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion and negative assurance letter, dated such date, of counsel representing the Company for the purposes of such Registration, addressed to the Holders, the placement agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given as the Holders, placement agent, sales agent, or Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters, and may be found reasonably satisfactory to a majority in interest of the participating Holders;

Section 3.3 Requirements for Participation in Underwritten Offerings.

Section 3.4 Suspension of Sales; Adverse Disclosure.

3.4.1 The Company shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement for a reasonable period of time, not to exceed 90 calendar days in any 360-day period (i) during any customary blackout or similar period or as permitted hereunder and (ii) as may be necessary in connection with the preparation and filing of a post-effective amendment to the Registration Statement following the filing of the Issuer’s Annual Report on Form 10-K for its first completed fiscal year.

3.4.2 Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until such Holder has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplemented or amended Prospectus as soon as practicable after the time of such notice), or until he, she or it is advised in writing by the Company that the use of the Prospectus may be resumed. If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would require the Company to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities. The Company shall immediately notify the Holders of the expiration of any period during which it exercised its rights under this Section 3.4, and upon the expiration of such period the Holders shall be entitled to resume the use of any such Prospectus in connection with any sale or offer to sell Registrable Securities, and upon the expiration of such period the Holders shall be entitled to resume the use of any such Prospectus in connection with any sale or offer to sell Registrable Securities

Section 3.5 Reporting Obligations.

The Company further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission), including providing any legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

ARTICLE IV

INDEMNIFICATION AND CONTRIBUTION

Section 4.1 Indemnification by the Company. The Company agrees to indemnify, to the extent permitted by law, and hold harmless each Holder of Registrable Securities, its officers and directors and each person who controls such Holder (within the meaning of the Securities Act) from and against any losses, claims, damages, liabilities and expenses (including reasonable attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus, or any amendment or supplement to any of them, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, except insofar as the same is contained in any information furnished in writing to the Company by the Holder expressly for use therein. The Company also shall indemnify any Underwriter of the Registrable Securities, their officers and directors and each person who controls such Underwriter (within the meaning of the Securities Act) on substantially the same basis as that of the indemnification of the Holder provided in this Section 4.1.

Section 4.2 Indemnification by Holders of Registrable Securities. In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. Each Holder shall indemnify any Underwriter of Registrable Securities sold by such Holder, their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

Section 4.3 Conduct of Indemnification Proceedings. Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

Section 4.4 Survival. The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Xxxxxx’s indemnification is unavailable for any reason.

Section 4.5 Contribution. If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, that the liability of any Holder under this Section 4.5 shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4.1, 4.2 and 4.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this Section 4.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.5 from any person who was not guilty of such fraudulent misrepresentation.

Each of the parties irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in

any Action arising out of or relating to this Agreement or the transactions contemplated hereby, (i) any claim that he, she or it is not personally subject to the jurisdiction of the courts in Delaware as described herein for any reason, (ii) that he, she or it or his, her or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) that (A) the Action in any such court is brought in an inconvenient forum, (B) the venue of such Action is improper or (C) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

2. Lock-Up.

2.1 Lock-Up. Each Lock-Up Party severally, and not jointly, agrees with GigCapital5 not to effect any Transfer, or make a public announcement of any intention to effect such Transfer, of any Lock-Up Securities Beneficially Owned or otherwise held by such Lock-Up Party during the Lock-Up Period (as defined below); provided, that such prohibition shall not apply to Transfers permitted pursuant to Section 2.2. The “Lock-Up Period” shall be the period commencing on the Closing Date and ending on the date that is the earlier to occur of:

(a) six (6) months following the Closing Date; (b) subsequent to the Closing, the date on which the reported closing price of one share of GigCapital5 Common Stock quoted on The Nasdaq Stock Market LLC, the New York Stock Exchange or the NYSE American (or the exchange on which the shares of GigCapital5 Common Stock are then listed) equals or exceeds eleven dollars and fifty cents ($11.50) per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like occurring after the Closing Date) for any twenty (20) Trading Days (as defined below) within any thirty (30) consecutive Trading Day period commencing at least ninety (90) days after the Closing Date; and (c) subsequent to the Closing, the date on which GigCapital5 completes a liquidation, merger, stock exchange or other similar transaction that results in all of GigCapital5’s stockholders having the right to exchange their GigCapital5 Securities for cash, securities or other property. “Trading Day” means a day on which shares of GigCapital5 Common Stock are actually traded on the principal securities exchange or securities market on which shares of GigCapital5 Common Stock are then traded; provided, however, that if the GigCapital5 Common Stock is not so listed or admitted for trading, Trading Day means a Business Day. For the avoidance of any doubt, each Lock-Up Party shall retain all of his, her or its rights as a stockholder of GigCapital5 during the Lock-Up Period, including the right to vote, and to receive any dividends and distributions in respect of, any Lock-Up Securities.

2.2 Permitted Transfers. Notwithstanding anything to the contrary contained in this Agreement, during the Lock-Up Period, each Lock-Up Party may Transfer, without the consent of GigCapital5, any of such Lock-Up Party’s Lock-Up Securities (a) to any of such Lock-Up Party’s Permitted Transferees, upon written notice to GigCapital5 or (b) pursuant to any liquidation, merger, stock exchange or other similar transaction which results in all of GigCapital5’s stockholders having the right to exchange their GigCapital5 Securities for cash, securities or other property subsequent to the Merger; provided, that in connection with any Transfer of such Lock-Up Securities, the restrictions and obligations contained in Section 2.1 and this Section 2.2 will continue to apply to such Lock-Up Securities after any Transfer of such Lock-Up Securities and such transferee shall execute a lock-up agreement substantially in the form of this Agreement for the balance of the Lock-Up Period. Notwithstanding the foregoing provisions of this Section 2.2, a Lock-Up Party may (i) not make a Transfer to a Permitted Transferee if such Transfer has as a purpose the avoidance of or is otherwise undertaken in contemplation of avoiding the restrictions on Transfers in this Agreement (it being understood that the purpose of this provision includes prohibiting the Transfer to a Permitted Transferee (A) that has been formed to facilitate a material change with respect to who or which entities Beneficially Own the Lock-Up Securities, or (B) followed by a change in the relationship between the Lock-Up Party and the Permitted Transferee (or a change of control of such Lock-Up Party or Permitted Transferee) after the Transfer with the result and effect that the Lock-Up Party has indirectly made a Transfer of Lock-Up Securities by using a Permitted Transferee, which Transfer would not have been directly permitted under this Section 2 had such change in such relationship occurred prior to such Transfer), or (ii) enter into a written plan meeting the requirements of Rule 10b5-1 under the Exchange Act after the date of this Agreement relating to the sale of the undersigned’s Lock-Up Securities, provided that (A) the securities subject to such plan may not be sold until after the expiration of the Lock-Up Period and (B) the Company shall not be required to effect, and the undersigned shall not effect or cause to be effected, any public filing, report or other public announcement regarding the establishment of the trading plan.

3. Confidentiality. Until the Expiration Time, each Lock-Up Party will and will direct his, her or its Affiliates to keep confidential and not disclose any non-public information relating to GigCapital5 or the Company and their respective subsidiaries, including the existence or terms of, or transactions contemplated by, this Agreement, the Business Combination Agreement or the other Transaction Documents, except to the extent that such information (i) was, is or becomes generally available to the public after the date hereof other than as a result of a disclosure by such Lock-Up Party in breach of this Section 3, (ii) is, was or becomes available to such Lock-Up Party on a non-confidential basis from a source other than GigCapital5 or the Company, or (iii) is or was independently developed by such Lock-Up Party after the date hereof. Notwithstanding the foregoing, such information may be disclosed to the extent required to be disclosed in a judicial or administrative proceeding, or otherwise required to be disclosed by applicable Law (including complying with any oral or written questions, interrogatories, requests for information or documents, subpoena, civil investigative demand or similar process to which such disclosing party is subject), provided that such Lock-Up Party gives GigCapital5 or the Company, as applicable, prompt notice of such request(s) or requirement(s), to the extent practicable (and not prohibited by Law), so that

GigCapital5 or the Company may seek, at its expense, an appropriate protective order or similar relief (and such Lock-Up Party shall reasonably cooperate with such efforts it being understood that such obligation to reasonably cooperate does not require a Lock-Up Party to himself, herself or itself commence litigation regarding such protective order or similar relief).

4. Representations and Warranties of the Lock-Up Parties. Each Lock-Up Party hereby represents and warrants, severally and not jointly, to the Company and GigCapital5 as follows:

4.1 Due Authority. Such Lock-Up Party has the full power and authority to execute and deliver this Agreement and perform his, her or its obligations hereunder. If such Lock-Up Party is an individual, the signature to this agreement is genuine and such Lock-Up Party has legal competence and capacity to execute the same. This Agreement has been duly and validly executed and delivered by such Lock-Up Party and, assuming due execution and delivery by the other parties hereto, constitutes a legal, valid and binding obligation of such Lock-Up Party, enforceable against such Lock-Up Party in accordance with its terms, except as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, and by general equitable principles.

4.2 No Conflict; Consents.

(a) The execution and delivery of this Agreement by such Lock-Up Party does not, and the performance by such Lock-Up Party of the obligations under this Agreement and the compliance by such Lock-Up Party with any provisions hereof do not and will not: (i) conflict with or violate any Law applicable to such Lock-Up Party, (ii) if such Lock-Up Party is an entity, conflict with or violate the certificate of incorporation or bylaws or any equivalent Organizational Documents of such Lock-Up Party, or (iii) result in any breach of, or constitute a default (or an event, which with notice or lapse of time or both, would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of a lien on any of the securities of the Company owned by such Lock-Up Party pursuant to any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation to which such Lock-Up Party is a party or by which such Lock-Up Party is otherwise bound, except, in the case of clauses (i) and (iii), as would not reasonably be expected, individually or in the aggregate, to materially impair the ability of such Lock-Up Party to perform his, her or its obligations hereunder or to consummate the transactions contemplated hereby.

(b) The execution and delivery of this Agreement by such Lock-Up Party does not, and the performance of this Agreement by such Lock-Up Party will not, require any consent, approval, authorization or permit of, or filing or notification to, or expiration of any waiting period by any Governmental Authority, other than those set forth as conditions to closing in the Business Combination Agreement.

4.3 Absence of Litigation. As of the date hereof, there is no litigation, suit, claim, charge, grievance, action, proceeding, audit or investigation by or before any Governmental Authority (an “Action”) pending against, or, to the knowledge of such Lock-Up Party, threatened against such Lock-Up Party that would reasonably be expected to materially impair the ability of such Lock-Up Party to perform his, her or its obligations hereunder or to consummate the transactions contemplated hereby.

4.4 Absence of Conflicting Agreements. Such Lock-Up Party has not entered into any agreement, arrangement or understanding that is otherwise materially inconsistent with, or would materially interfere with, or prohibit or prevent him, her or it from satisfying, his, her or its obligations pursuant to this Agreement.

5. Fiduciary Duties. The covenants and agreements set forth herein shall not prevent any designee of any Lock-Up Party from serving on the Board of Directors or as an officer of the Company or from taking any action, subject to the provisions of the Business Combination Agreement, while acting in such designee’s capacity as a director or officer of the Company. Each Lock-Up Party is entering into this Agreement solely in his, her or its capacity as the anticipated owner of GigCapital5 Securities following the consummation of the Merger.

6. Termination. This Agreement shall terminate upon the earlier of: (i) termination of the Business Combination Agreement in accordance with its terms; or (ii) completion of the Lock-Up as specified in Section 2.1 of this Agreement. Upon termination of this Agreement, none of the parties hereto shall have any further obligations or liabilities under this Agreement; provided, that nothing in this Section 6 shall relieve any party hereto of liability for any willful material breach of this Agreement prior to its termination.

7. Miscellaneous.

7.1 Severability. In the event that any term, provision, covenant or restriction of this Agreement, or the application thereof, is held to be illegal, invalid or unenforceable under any present or future Law: (a) such provision will be fully severable; (b) this Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof; (c) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by the illegal, invalid or unenforceable provision or by its severance therefrom; and (d) in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms of such illegal, invalid or unenforceable provision as may be possible.

7.2 Non-survival of Representations and Warranties. None of the representations or warranties in this Agreement or in any schedule, instrument or other document delivered pursuant to this Agreement shall survive the Expiration Time.

7.3 Assignment. Neither party hereto may assign, directly or indirectly, including, through any merger, acquisition, sale of all or substantially all shares/assets or by operation of Law, either this Agreement or any of his, her or its rights, interests or obligations hereunder without the prior written approval of the other parties hereto, except with respect to a Transfer completed in accordance with Section 2.2. Subject to the first sentence of this Section 7.3, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns. Any assignment in violation of this Section 7.3 shall be void ab initio.

7.4 Amendments and Modifications. This Agreement may be amended by the parties hereto at any time by execution of an instrument in writing signed by (a) GigCapital5, (b) the Company and (c) (i) by Lock-Up Parties holding at least fifty percent (50%) of the Lock-Up Securities (assuming the hypothetical exercise of all then-outstanding warrants and options that are Lock-Up Securities) that are then subject to this Agreement, and any such amendment shall be binding on all the Lock-Up Parties; provided, however, that in no event shall the obligation of any Lock-Up Party hereunder be materially increased without the prior written consent of such Lock-Up Party, unless such amendment applies to all Lock-Up Parties in the same fashion; provided, further, however, that (A) if this Agreement, or any other lock-up agreement signed by a stockholder of the Company in connection with the transactions contemplated hereby or under the Business Combination Agreement, is amended, modified or waived in a manner favorable to any Lock-Up Party or such shareholder, and such amendment, modification or waiver would be favorable to any other Lock-Up Party, this Agreement shall be automatically amended in the same manner with respect to such other Lock-Up Party (and GigCapital5 shall provide prompt notice thereof to all Lock-Up Parties), and (B) if any Lock-Up Party or such shareholder is released from any or all of the lock-up restrictions under this Lock-Up Agreement or such other lock-up agreement, each other Lock-Up Party shall automatically be contemporaneously and proportionately released from the lock-up restrictions hereunder (which, for the avoidance of doubt, will include a release of the same percentage of such Lock-Up Party’s Lock-Up Securities) and GigCapital5 shall provide prompt notice thereof to each Lock-Up Party.

7.8 Counterparts. This Agreement may be executed and delivered (including by facsimile or portable document format (pdf) transmission) in one or more counterparts, and by the different parties in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

7.10 Legal Representation. Each of the parties hereto agrees that he, she or it has been represented by independent counsel of his, her or its choice during the negotiation and execution of this Agreement and each party hereto and his, her or its counsel cooperated in the drafting and preparation of this Agreement and the documents referred to herein and, therefore, waive the application of any Law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party hereto drafting such agreement or document.

No failure or delay on the part of any party to exercise any power, right, privilege or remedy under this Agreement shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. No party shall be deemed to have waived any claim available to such party arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such waiving party; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

7.14 Several Liability. The liability of the Lock-Up Parties hereunder is several (and not joint).

BOARD OF DIRECTORS

Section 5.1 Board Powers. The business and affairs of the Corporation shall be managed by, or under the direction of, the Board. In addition to the powers and authority expressly conferred upon the Board by statute, this Second Amended and Restated Certificate or the Bylaws of the Corporation (as they may be amended from time to time, “Bylaws”), the Board is hereby empowered to exercise all such powers and do all such acts and things as may be exercised or done by the Corporation, subject, nevertheless, to the provisions of the DGCL, this Second Amended and Restated Certificate, and any Bylaws adopted by the stockholders of the Corporation; provided, however, that no Bylaws hereafter adopted by the stockholders of the Corporation shall invalidate any prior act of the Board that would have been valid if such Bylaws had not been adopted.

Section 5.2 Number, Election and Term.

(a) The number of directors of the Corporation, other than those who may be elected by the holders of one or more series of the Preferred Stock voting separately by class or series, shall be fixed from time to time exclusively by the Board pursuant to a resolution adopted by a majority of the Board.

(b) Subject to Section 5.5 hereof, the Board shall be divided into three classes, as nearly equal in number as possible and designated Class I, Class II, and Class III. The Board is authorized to assign members of the Board already in office to Class I, Class II, or Class III. The term of the initial Class I Directors shall expire at the first annual meeting of the stockholders of the Corporation following the effectiveness of this Second Amended and Restated Certificate, the term of the initial Class II Directors shall expire at the second annual meeting of the stockholders of the Corporation following the effectiveness of this Second Amended and Restated Certificate, and the term of the initial Class III directors shall expire at the third annual meeting of the stockholders following the effectiveness of this Second Amended and Restated Certificate. At each succeeding annual meeting of the stockholders of the Corporation, beginning with the first annual meeting of the stockholders of the Corporation following the effectiveness of this Second Amended and Restated Certificate, each of the successors elected to replace the class of directors whose term expires at that annual meeting shall be elected for a three year term or until the election and qualification of their respective successors in office, subject to their earlier death, resignation or removal. Subject to Section 5.5 hereof, if the number of directors that constitutes the Board is changed, any increase or decrease shall be apportioned by the Board among the classes so as to maintain the number of directors in each class as nearly equal as possible, but in no case shall a decrease in the number of directors constituting the Board shorten the term of any incumbent director. Subject to the rights of the holders of one or more series of Preferred Stock, voting separately by class or series, to elect directors pursuant to the terms of one or more series of Preferred Stock, the election of directors shall be determined by a plurality of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon. The Board is hereby expressly authorized, by resolution or resolutions thereof, to assign members of the Board already in office to the aforesaid classes at the time this Second Amended and Restated Certificate (and therefore such classification) becomes effective in accordance with the DGCL.

(c) Subject to Section 5.5 hereof, a director shall hold office until the next annual meeting for the year in which his or her term expires and until his or her successor has been elected and qualified, subject, however, to such director’s earlier death, resignation, retirement, disqualification or removal.

(d) Unless and except to the extent that the Bylaws shall so require, the election of directors need not be by written ballot. The holders of shares of Common Stock shall not have cumulative voting rights.

Section 5.3 Newly Created Directorships and Vacancies. Subject to Section 5.5 hereof, newly created directorships resulting from an increase in the number of directors and any vacancies on the Board resulting from death, resignation, retirement, disqualification, removal or other cause may be filled solely and exclusively by a majority vote of the remaining directors then in office, even if less than a quorum, or by a sole remaining director (and not by stockholders), and any director so chosen shall hold office for the remainder of the full term of the

class of directors to which the new directorship was added or in which the vacancy occurred and until his or her successor has been elected and qualified, subject, however, to such director’s earlier death, resignation, retirement, disqualification or removal.

Section 5.4 Removal. Subject to Section 5.5 hereof, any or all of the directors may be removed from office, but only for cause, by the affirmative vote of holders of a majority of the voting power of all then outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class, at a meeting called for that purpose.

Section 5.5 Preferred Stock—Directors. Notwithstanding any other provision of this Article V, and except as otherwise required by law, whenever the holders of one or more series of the Preferred Stock shall have the right, voting separately by class or series, to elect one or more directors, the term of office, the filling of vacancies, the removal from office and other features of such directorships shall be governed by the terms of such series of the Preferred Stock as set forth in this Second Amended and Restated Certificate (including any Preferred Stock Designation) and such directors shall not be included in any of the classes created pursuant to this Article V unless expressly provided by such terms.

ARTICLE VI

BYLAWS

In furtherance and not in limitation of the powers conferred upon it by law, the Board shall have the power and is expressly authorized to adopt, amend, alter or repeal the Bylaws by the affirmative vote of a majority of the total number of directors present at a regular or special meeting of the Board at which there is a quorum or by unanimous written consent. The Bylaws also may be adopted, amended, altered or repealed by the stockholders of the Corporation; provided, however, that in addition to any vote of the holders of any class or series of capital stock of the Corporation required by law or by this Second Amended and Restated Certificate (including any Preferred Stock Designation), the affirmative vote of the holders of at least a majority of the voting power of all then outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class, shall be required for the stockholders of the Corporation to adopt, amend, alter or repeal the Bylaws; and provided further, however, that no Bylaws hereafter adopted by the stockholders of the Corporation shall invalidate any prior act of the Board that would have been valid if such Bylaws had not been adopted.

ARTICLE VII

SPECIAL MEETINGS OF STOCKHOLDERS; ACTION BY WRITTEN CONSENT

Section 7.1 Special Meetings. Subject to the rights, if any, of the holders of any outstanding series of the Preferred Stock, and to the requirements of applicable law, special meetings of stockholders of the Corporation may be called only by the Chairman of the Board, Chief Executive Officer of the Corporation, or the Board pursuant to a resolution adopted by a majority of the Board, and the ability of the stockholders of the Corporation to call a special meeting is hereby specifically denied. Except as provided in the foregoing sentence, special meetings of stockholders of the Corporation may not be called by another person or persons.

Section 7.2 Advance Notice. Advance notice of stockholder nominations for the election of directors and of business to be brought by stockholders before any meeting of the stockholders of the Corporation shall be given in the manner provided in the Bylaws.

Section 7.3 Action by Written Consent. Except as may be otherwise provided for or fixed pursuant to this Second Amended and Restated Certificate (including any Preferred Stock Designation) relating to the rights of the holders of any outstanding series of Preferred Stock, any action required or permitted to be taken by the stockholders of the Corporation must be effected by a duly called annual or special meeting of such stockholders and may not be effected by written consent of the stockholders of the Corporation.

ARTICLE VIII

LIMITED LIABILITY; INDEMNIFICATION

Section 8.1 Limitation of Director Liability. A director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or may hereafter be amended unless a director violated his or her duty of loyalty to the Corporation or its stockholders, acted in bad faith, knowingly or intentionally violated the law, authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or derived improper personal benefit from his or her actions as a director. Any amendment, modification or repeal of the foregoing sentence shall not adversely affect any right or protection of a director of the Corporation hereunder in respect of any act or omission occurring prior to the time of such amendment, modification or repeal.

Section 8.2 Indemnification and Advancement of Expenses.

(a) To the fullest extent permitted by applicable law, as the same exists or may hereafter be amended, the Corporation shall indemnify and hold harmless each person who is or was made a party or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”) by reason of the fact that he or she is or was a director or officer of the Corporation or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, other enterprise or nonprofit entity, including service with respect to an employee benefit plan (an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent, or in any other capacity while serving as a director, officer, employee or agent, against all liability and loss suffered and expenses (including, without limitation, attorneys’ fees, judgments, fines, XXXXX excise taxes and penalties and amounts paid in settlement) reasonably incurred by such indemnitee in connection with such proceeding. The Corporation shall to the fullest extent not prohibited by applicable law pay the expenses (including attorneys’ fees) incurred by an indemnitee in defending or otherwise participating in any proceeding in advance of its final disposition; provided, however, that, to the extent required by applicable law, such payment of expenses in advance of the final disposition of the proceeding shall be made only upon receipt of an undertaking, by or on behalf of the indemnitee, to repay all amounts so advanced if it shall ultimately be determined that the indemnitee is not entitled to be indemnified under this Section 8.2 or otherwise. The rights to indemnification and advancement of expenses conferred by this Section 8.2 shall be contract rights and such rights shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators. Notwithstanding the foregoing provisions of this Section 8.2(a), except for proceedings to enforce rights to indemnification and advancement of expenses, the Corporation shall indemnify and advance expenses to an indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board.

(b) The rights to indemnification and advancement of expenses conferred on any indemnitee by this Section 8.2 shall not be exclusive of any other rights that any indemnitee may have or hereafter acquire under law, this Second Amended and Restated Certificate, the Bylaws, an agreement, vote of stockholders or disinterested directors, or otherwise.

(c) Any repeal or amendment of this Section 8.2 by the stockholders of the Corporation or by changes in law, or the adoption of any other provision of this Second Amended and Restated Certificate inconsistent with this Section 8.2, shall, unless otherwise required by law, be prospective only (except to the extent such amendment or change in law permits the Corporation to provide broader indemnification rights on a retroactive basis than permitted prior thereto), and shall not in any way diminish or adversely affect any right or protection existing at the time of such repeal or amendment or adoption of such inconsistent provision in respect of any proceeding (regardless of when such proceeding is first threatened, commenced or completed) arising out of, or related to, any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision.

(d) This Section 8.2 shall not limit the right of the Corporation, to the extent and in the manner authorized or permitted by law, to indemnify and to advance expenses to persons other than indemnitees.

ARTICLE IX

CORPORATE OPPORTUNITY

Section 9.1 Corporate Opportunities and Non-Employee Directors.

(a) In recognition and anticipation that members of the Board who are not employees of the Corporation (the “Non-Employee Directors”) and their respective Affiliates may now engage and may continue to engage in the same or similar activities or related lines of business as those in which the Corporation, directly or indirectly, may engage and/or other business activities that overlap with or compete with those in which the Corporation, directly or indirectly, may engage, the provisions of this Article IX are set forth to regulate and define the conduct of certain affairs of the Corporation with respect to certain classes or categories of business opportunities as they may involve any of the Non-Employee Directors or their respective Affiliates and the powers, rights, duties and liabilities of the Corporation and its directors, officers and stockholders in connection therewith. For purposes of this Article IX, (i) “Affiliate” shall mean, (a) in respect of each Non-Employee Director, any Person that, directly or indirectly, is controlled by such Non-Employee Director (other than the Corporation and any entity that is controlled by the Corporation) and (b) in respect of the Corporation, any Person that, directly or indirectly, is controlled by the Corporation; and (ii) “Person” shall mean any individual, corporation, general or limited partnership, limited liability company, joint venture, trust, association or any other entity.

(b) No Non-Employee Director (including any Non-Employee Director who serves as an officer of the Corporation in both his or her director and officer capacities) or his or her Affiliates (such Persons being referred to, collectively, as “Identified Persons” and, individually, as an “Identified Person”) shall, to the fullest extent permitted by law, have any duty to refrain from directly or indirectly (1) engaging in the same or similar business activities or lines of business in which the Corporation or any of its Affiliates now engages or proposes to engage or (2) otherwise competing with the Corporation or any of its Affiliates, and, to the fullest extent permitted by law, no Identified Person shall be liable to the Corporation or its stockholders or to any Affiliate of the Corporation for breach of any fiduciary duty solely by reason of the fact that such Identified Person engages in any such activities. To the fullest extent permitted by law, the Corporation hereby renounces any interest or expectancy in, or right to be offered an opportunity to participate in, any business opportunity which may be a corporate opportunity for an Identified Person and the Corporation or any of its Affiliates, except as provided in Section 9.1(c) of this Article IX. Subject to said Section 9.1(c) of this Article IX, in the event that any Identified Person acquires knowledge of a potential transaction or other business opportunity which may be a corporate opportunity for itself, herself or himself and the Corporation or any of its Affiliates, such Identified Person shall, to the fullest extent permitted by law, have no duty to communicate or offer such transaction or other business opportunity to the Corporation or any of its Affiliates and, to the fullest extent permitted by law, shall not be liable to the Corporation or its stockholders or to any Affiliate of the Corporation for breach of any fiduciary duty as a stockholder, director or officer of the Corporation solely by reason of the fact that such Identified Person pursues or acquires such corporate opportunity for itself, herself or himself, or offers or directs such corporate opportunity to another Person.

(c) The Corporation does not renounce its interest in any corporate opportunity offered to any Non-Employee Director (including any Non-Employee Director who serves as an officer of this Corporation) if such opportunity is expressly offered to such person solely in his or her capacity as a director or officer of the Corporation, and the provisions of Section 9.1(b) of this Article IX shall not apply to any such corporate opportunity.

(d) In addition to and notwithstanding the foregoing provisions of this Article IX, a corporate opportunity shall not be deemed to be a potential corporate opportunity for the Corporation if it is a business opportunity that (i) the Corporation is unable, financially or legally, or is not contractually permitted to undertake, (ii) from its nature, is not in the line of the Corporation’s business or is of no practical advantage to the Corporation or (iii) is one in which the Corporation has no interest or reasonable expectancy.

(e) To the fullest extent permitted by law, any Person purchasing or otherwise acquiring any interest in any shares of capital stock of the Corporation shall be deemed to have notice of and to have consented to the provisions of this Article IX.

(f) Neither the alteration, amendment, addition to or repeal of this Article IX, nor the adoption of any provision of this Second Amended and Restated Certificate (including any Preferred Stock Designation) inconsistent with this Article IX, shall eliminate or reduce the effect of this Article IX in respect of any corporate opportunity first identified or any other matter occurring, or any cause of action, suit or claim that, but for this Article IX, would accrue or arise, prior to such alteration, amendment, addition, repeal or adoption.

ARTICLE X

AMENDMENT OF SECOND AMENDED AND RESTATED CERTIFICATE OF INCORPORATION

The Corporation reserves the right at any time and from time to time to amend, alter, change or repeal any provision contained in this Second Amended and Restated Certificate (including any Preferred Stock Designation), and other provisions authorized by the laws of the State of Delaware at the time in force that may be added or inserted, in the manner now or hereafter prescribed by this Second Amended and Restated Certificate and the DGCL; and, except as set forth in Article VIII, all rights, preferences and privileges of whatever nature herein conferred upon stockholders, directors or any other persons by and pursuant to this Second Amended and Restated Certificate in its present form or as hereafter amended are granted subject to the right reserved in this Article X.

ARTICLE XI

EXCLUSIVE FORUM FOR CERTAIN LAWSUITS

Section 11.1 Forum. Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for any stockholder (including a beneficial owner) to bring (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Corporation to the Corporation or the Corporation’s stockholders, (iii) any action asserting a claim against the Corporation, its directors, officers or employees arising pursuant to any provision of the DGCL or this Second Amended and Restated Certificate or the Bylaws, or (iv) any action asserting a claim against the Corporation, its directors, officers or employees governed by the internal affairs doctrine and, if brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s counsel except any action (A) as to which the Court of Chancery in the State of Delaware determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), (B) which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or (C) for which the Court of Chancery does not have subject matter jurisdiction. Notwithstanding the foregoing, the provisions of this Section 11.1 will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Notwithstanding the foregoing, the federal district courts of the United States of America, to the fullest extent permitted by law, shall be the sole and exclusive forum for the resolution of any action asserting a cause of action arising under the Securities Act. Any person or entity purchasing or otherwise acquiring any interest in any security of the Corporation shall be deemed to have notice of and consented to the provisions of this Section 11.1.

Section 11.2 Consent to Jurisdiction. If any action the subject matter of which is within the scope of Section 11.1 immediately above is filed in a court other than a court located within the State of Delaware (a “Foreign Action”) in the name of any stockholder, such stockholder shall be deemed to have consented to (i) the personal jurisdiction of the state and federal courts located within the State of Delaware in connection with any action brought in any such court to enforce Section 11.1 immediately above (an “FSC Enforcement Action”) and (ii) having service of process made upon such stockholder in any such FSC Enforcement Action by service upon such stockholder’s counsel in the Foreign Action as agent for such stockholder.
