 Exhibit 10.1 

AMENDMENT TO 

SUBSCRIPTION AGREEMENT 

THIS AMENDMENT TO SUBSCRIPTION AGREEMENT (this “Amendment”), is entered into on June 8, 2021, by and between
GigCapital2, Inc., a Delaware corporation (the “Company”), and [•] (“Subscriber”). Capitalized terms used herein but not otherwise defined herein shall have the definitions ascribed to them in the
Subscription Agreement (as defined below). 
 WHEREAS, pursuant to a separate subscription agreement dated January 20, 2021 (the
“Subscription Agreement”), the Subscriber subscribed for and agreed to purchase from the Company, immediately prior to the consummation of the Transaction, a specified number of shares of the Company’s common stock, par
value $0.0001 per share (the “Common Stock”), as set forth on the signature page of the Subscription Agreement (the “Subscribed Shares”) for a purchase price of $10.00 per share (the “Per
Share Price” and the aggregate of such Per Share Price for all Subscribed Shares being referred to herein as the “Purchase Price”), and the Company agreed to issue and sell to the Subscriber the Subscribed Shares
in consideration of the payment of the Purchase Price by or on behalf of Subscriber to the Company; 
 WHEREAS, in connection with the
issuance of the Subscribed Shares on the Closing Date, the Company will enter into an Amended and Restated Warrant Agreement in substantially the form attached hereto as Exhibit A (the “Warrant Agreement”) in
respect of the PIPE Financing Warrants (as defined below and in Exhibit A); and 
 WHEREAS, the Company and the Subscriber desire to
amend the Subscription Agreement to provide that, upon payment of the Purchase Price at the Closing, the Subscriber will acquire, in addition to the Subscribed Shares, PIPE Financing Warrants for the purchase of one (1) share of Common Stock
for each ten (10) Subscribed Shares, but to otherwise effectuate no change to the terms of the Subscription Agreement (including the aggregate Purchase Price to be paid by the Subscriber). 

NOW, THEREFORE, the parties hereto agree as follows: 

1. Capitalized terms used herein but not otherwise defined herein shall have the definitions ascribed to them in the Subscription Agreement.

 2. The first sentence of Section 1 of the Subscription Agreement is hereby amended to read in full as follows: 

1. Subscription. Subject to the terms and conditions hereof, at the Closing (as defined below), Subscriber hereby agrees to
subscribe for and purchase, and the Company hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, (a) the Subscribed Shares plus (b) warrants (the “PIPE Financing Warrants”) to
purchase one (1) share of Common Stock for every ten (10) Subscribed Shares (such subscription and issuance, the “Subscription”). 
  

 3. The second and third sentences of Section 2.b. of the Subscription Agreement are
hereby amended to read in full as follows: 
 No later than two (2) Business Days after receiving the Closing Notice, Subscriber shall
deliver to the Company such information as is reasonably requested in the Closing Notice in order for the Company to issue the Subscribed Shares and PIPE Financing Warrants to Subscriber. Subscriber shall deliver to the Company, on or prior to 8:00
a.m. (Eastern time) (or as soon as practicable after the Company or its transfer agent delivers evidence of the issuance to Subscriber of the Subscribed Shares on and as of the Closing Date) on the Closing Date the Purchase Price in cash via wire
transfer to the account specified in the Closing Notice against (and concurrently with) delivery by the Company to Subscriber of (i) the Subscribed Shares in book entry form, free and clear of any liens or other restrictions (other than those
arising under this Subscription Agreement or state or federal securities laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions) or to a custodian designated by Subscriber, as applicable, (ii) a Warrant
Agreement executed by the Company, evidencing the issuance to Subscriber of the applicable number of PIPE Financing Warrants on and as of the Closing Date, subject to the Subscriber’s execution of such Warrant Agreement, and (iii) written
notice from the Company or its transfer agent evidencing the issuance to Subscriber of the Subscribed Shares and such PIPE Financing Warrants on and as of the Closing Date. 

4. The following is added as a new Section 5(a1), to be inserted between current Sections 5.a. and 5.b. of the Subscription Agreement:

 a1. The Company agrees that, within forty five (45) calendar days after the consummation of the Transaction (the
“Second Filing Deadline”), the Company will file with the Commission (at the Company’s sole cost and expense) a new registration statement (the “Second Registration Statement” and, together with the
Registration Statement referenced in Section 5.a., the “Registration Statements”) registering the resale of the PIPE Financing Warrants (“Additional Registrable Securities,” and, together with the Subscribed
Shares, the “Registrable Securities”), and the Company shall use its commercially reasonable efforts to have the Second Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the
60th calendar day (or 90th calendar day if the Commission notifies the Company that it will “review” the Second Registration Statement) following the Filing Deadline (such date, the “Second Effectiveness Date”); provided,
however, that the Company’s obligations to include the Additional Registrable Securities in the Second Registration Statement are contingent upon the undersigned furnishing in writing to the Company such information regarding the undersigned,
the securities of the Company held by the undersigned and the intended method of disposition of the Additional Registrable Securities as shall be reasonably requested by the Company to effect the registration of the Additional Registrable
Securities, and shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations. In no event shall the Subscriber be identified as a statutory
underwriter in the Second Registration Statement unless requested by the Commission; provided, that if the Commission requests that the Subscriber be identified as a statutory underwriter in the Second Registration Statement, the Subscriber will
have an opportunity to withdraw from the Second Registration Statement. Notwithstanding the foregoing, if the Commission 

  
 2 

 
prevents the Company from including any or all of the securities proposed to be registered under the Second Registration Statement due to limitations on the use of Rule 415 of the Securities
Act for the resale of the Additional Registrable Securities by the applicable shareholders or otherwise, such Second Registration Statement shall register for resale such number of Additional Registrable Securities which is equal to the maximum
number of Additional Registrable Securities as is permitted by the SEC. In such event, the number of Additional Registrable Securities to be registered for each selling shareholder named in the Second Registration Statement shall be reduced pro rata
among all such selling shareholders. The Company will use its commercially reasonable efforts to maintain the continuous effectiveness of the Second Registration Statement, and to be supplemented and amended to the extent necessary to ensure that
such Second Registration Statement is available or, if not available, that another registration statement is available for the resale of the Additional Registrable Securities, until the earliest of (i) the date on which the Additional
Registrable Securities may be resold without volume or manner of sale limitations pursuant to Rule 144 promulgated under the Securities Act, (ii) the date on which such Additional Registrable Securities have actually been sold and
(iii) the date which is three years after the Closing. For purposes of clarification, any failure by the Company to file the Second Registration Statement by the Second Filing Deadline or to effect such Second Registration Statement by the
Second Effectiveness Date shall not otherwise relieve the Company of its obligations to file or effect the Second Registration Statement set forth in this Section 5. 

5. Sections 5.b. through 5.e. are hereby amended as follows: all references to “Registration Statement” are replaced with
“Registration Statements” and all references to “Subscribed Shares” are replaced with “Registrable Securities.” 

6. Except as expressly modified by this Amendment, all terms and conditions of the Subscription Agreement shall remain in full force and
effect. 
 7. This Amendment is governed by, and construed in accordance with, the laws of the state of New York. For avoidance of
doubt, the provisions of Section 8 (Miscellaneous) are applicable to this Amendment. 
 8. This Amendment may be
executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same agreement.

 NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as
follows: 
 1. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for
the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement. 

2. Warrants. 

2.1 Form of Warrant. Each Warrant shall initially be issued in registered form only. 

2.2 Effect of Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant
to this Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the holder thereof. 

  
 8 

 2.3 Registration. 

2.3.1 Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”), for the
registration of original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants in book-entry form, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof
in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. Ownership of beneficial interests in the Public Warrants shall be shown on, and the transfer of such ownership shall be effected
through, records maintained by institutions that have accounts with the Depositary (such institution, with respect to a Warrant in its account, a “Participant”). 

If The Depository Trust Company (the “Depositary”) subsequently ceases to make its book-entry settlement system
available for the Public Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Public Warrants are not eligible for, or it is no longer necessary to have the Public
Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depositary to deliver to the Warrant Agent for cancellation each book-entry Public Warrant, and the Company shall instruct the Warrant Agent to
deliver to the Depositary definitive certificates in physical form evidencing such Warrants which shall be in the form annexed hereto as Exhibit A. Notwithstanding anything herein to the contrary, any Initial Warrant, or portion thereof, may
be issued as part of, and be represented by, a Unit. Any Initial Warrant so issued shall have the same terms, force and effect as a certificated Initial Warrant that has been duly countersigned by the Warrant Agent in accordance with the terms of
this Agreement. 
 Certificates representing the Warrants, if issued, shall be signed by, or bear the facsimile signature of, the Chairman
of the Board, President, Chief Executive Officer, Chief Financial Officer, Secretary or other executive officer of the Company. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the
capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance. Each certificate representing a Private Placement Warrant shall
bear the legend set forth in Exhibit B hereto. Each certificate representing a PIPE Financing Warrant shall bear the legend set forth in Exhibit C hereto. 

2.3.2 Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent
may deem and treat the person in whose name such Warrant is registered in the Warrant Register (the “Registered Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby, for the purpose of any
exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. 

2.4 Detachability of Warrants. The Common Stock, Rights and Warrants comprising the Public Units trade separately. 

2.5 Private Placement Warrants. The Private Placement Warrants shall be identical to the Public Warrants, except that so long as they
are held by a Founder or any of its Permitted Transferees (as defined below) the Private Placement Warrants: (i) may be exercised for cash or on a cashless basis, pursuant to subsection 3.3.1(c) hereof, (ii) shall
be subject to the Lock-up (as defined below), and (iii) in accordance with Section 6.4 hereof shall not be redeemable by the Company; provided, however,
that in the case of (ii), the Private Placement Warrants and any shares of Common Stock held by a Founder or its Permitted Transferees and issued upon exercise of the Private Placement Warrants may be transferred by the holders thereof: 

(a) in the case of an individual, by bona fide gift to such person’s immediate family or to a trust, the beneficiary of which is a member
of such person’s immediate family, an affiliate of such person or to a charitable organization, 
 (b) amongst the Founders and their
affiliates, to the Company’s executive officers or directors, or to any affiliate or family member of any of the Company’s executive officers or directors, 

(c) in the case of an individual, by virtue of the laws of descent and distribution upon death of such person or pursuant to a qualified
domestic relations order, 

  
 9 

 (d) by certain pledges to secure obligations incurred in connection with purchases of the
Company’s securities, 
 (e) through private sales or transfers made in connection with the consummation of the Company’s initial
Business Combination at prices no greater than the price at which the Private Placement Warrants were originally purchased, or 
 (f) in
the event of the Company’s liquidation prior to the completion of the initial Business Combination, 
 (g) by virtue of the laws of
the state of Delaware and the holder’s limited liability company agreement, if applicable; provided, however, that, in the case of clauses (a) through (e) and (g), these transferees (the “Permitted
Transferees”) enter into a written agreement with the Company agreeing to be bound by the transfer restrictions in this Agreement. 

For the purposes of this Agreement, the term “Lock-up” means, (A) with
respect to all of the Private Placement Units, and the underlying Private Placement Warrants and shares of Common Stock underlying them (collectively, the “Private Placement Securities”), that such Private Placement
Securities may not be transferred, assigned or sold until the earlier to occur of: (A) one year after the completion of the Company’s initial Business Combination (as defined below) or (B) the date on which the Company completes a
liquidation, merger, stock exchange or other similar transaction after its initial Business Combination (as defined below) that results in all of its stockholders having the right to exchange their shares of Common Stock for cash, securities or
other property, provided, that, notwithstanding the foregoing, if the last sale price of the Common Stock equals or exceeds $12.50 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for
any 20 trading days within any 30-trading day period commencing at least 90 days after the Company’s initial Business Combination (as defined below), the Private Placement Securities will be released from
the Lock-up, subject to the following clause (B), if applicable; and, (B) with respect to the Private Placement Securities held only by EarlyBird and Northland Investment, and their Permitted Transferees,
that, notwithstanding any release from the Lock-up described in clause (A), the Private Placement Securities may not be sold, transferred, assigned, pledged or hypothecated for 180 days immediately following
the effective date of the Registration Statement except to any underwriter or selected dealer participating in the Offering and the bona fide officers or partners of the applicable Founder and any such participating underwriter or selected dealer,
nor may they be the subject of any hedging, short sale, derivative, put or call transaction that would result in the economic disposition of the Private Placement Securities by any person during such 180-day
period. As used in this Agreement, “trading day” means any day on which the Common Stock is traded on a national securities exchange or quoted for trading on one or more OTC Markets. 

2.6 Exercise Period for Certain Founders. Notwithstanding anything herein to the contrary, any Private Placement Warrants held by
EarlyBird or Northland Investment shall expire and not be exercisable on the date immediately following the fifth anniversary of the effective date of the Registration Statement. 

2.7 PIPE Financing Warrants. The PIPE Financing Warrants shall be identical to the Public Warrants, except that the PIPE Financing
Warrants in accordance with Section 6.5 hereof shall not be redeemable by the Company. 
 3. Terms and
Exercise of Warrants. 
 3.1 Exercise Price. Each Warrant shall, when countersigned by the Warrant Agent, entitle the
Registered Holder thereof, subject to the provisions of such Warrant and of this Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of $11.50 per share, subject to the adjustments provided
in Section 4 hereof and in the last sentence of this Section 3.1. The term “Exercise Price” as used in this Agreement shall mean the price per share at which shares of Common Stock may be
purchased at the time a Warrant is exercised. The Company in its sole discretion may lower the Exercise Price at any time prior to the Expiration Date (as defined below) for a period of not less than twenty (20) Business Days (a day, other than
a Saturday, Sunday or federal holiday, on which banks in New York City are generally open for normal business is a “Business Day”), provided, that the Company shall provide at least twenty (20) days prior written notice
of such reduction to Registered Holders of the Warrants and, provided further that any such reduction shall be identical among all of the Warrants. 

  
 10 

 3.2 Duration of Warrants. A Warrant may be exercised only during the period (the
“Exercise Period”) commencing on the later of: (i) the date that is thirty (30) days after the first date on which the Company completes its initial Business Combination, or (ii) the date that is twelve
(12) months from the date of the closing of the Offering, and terminating at 5:00 p.m., New York City time on the earlier to occur of: (x) the date that is five (5) years after the date on which the Company completes its initial
Business Combination, (y) the liquidation of the Company’s trust account in accordance with the Company’s amended and restated certificate of incorporation, as amended from time to time, if the Company fails to consummate an initial
Business Combination, or (z) other than with respect to the Private Placement Warrants and the PIPE Financing Warrants to the extent then held, directly or indirectly, by the original purchasers thereof or their Permitted Transferees, the
Redemption Date (as defined below) as provided in Section 6.2 hereof (the “Expiration Date”); provided, however, that the exercise of any Warrant shall be subject to the satisfaction of any
applicable conditions, as set forth in subsection 3.3.2 below, with respect to an effective registration statement. Except with respect to the right to receive the Redemption Price (as defined below) (other than with respect to a Private
Placement Warrant or a PIPE Financing Warrant to the extent then held, directly or indirectly, by the original purchasers thereof or their Permitted Transferees) in the event of a redemption (as set forth in Section 6
hereof), each Warrant (other than a Private Placement Warrant or a PIPE Financing Warrant, in the event of a redemption to the extent then held, directly or indirectly, by the original purchasers thereof or their Permitted Transferees) not exercised
on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m. New York City time on the Expiration Date. The Company in its sole discretion may extend
the duration of the Warrants by delaying the Expiration Date; provided, that the Company shall provide at least twenty (20) days prior written notice of any such extension to Registered Holders of the Warrants and, provided further that
any such extension shall be identical in duration among all the Warrants. 
 3.3 Exercise of Warrants. 

3.3.1 Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant, when countersigned by the Warrant Agent,
may be exercised by the Registered Holder thereof by surrendering it, at the office of the Warrant Agent, or at the office of its successor as Warrant Agent, in the Borough of Manhattan, City and State of New York, with the subscription form, as set
forth in the Warrant, duly executed, and by paying in full the Exercise Price for each share of Common Stock as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of
the Warrant for the shares of Common Stock and the issuance of such Common Stock, as follows: 
 (a) in lawful money of the United States,
in good certified check or good bank draft payable to the order of the Warrant Agent; 
 (b) in the event of a redemption pursuant
to Section 6 hereof in which the Company’s board of directors (the “Board”) has elected to require all holders of the Warrants to exercise such Warrants on a “cashless basis,” by surrendering
the Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the difference between the Exercise Price and the
Fair Market Value, as defined in this subsection 3.3.1(b) by (y) the Fair Market Value. Solely for purposes of this subsection 3.3.1(b) and Section 6.3, the “Fair Market
Value” shall mean the average reported last sale price of the Common Stock for the five (5) trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of the Warrants,
pursuant to Section 6 hereof; 
 (c) with respect to any Private Placement Warrant, so long as such Private Placement Warrant
is held by a Founder or a Permitted Transferee of a Founder, by surrendering the Private Placement Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common
Stock underlying the Warrants, multiplied by the difference between the Exercise Price and the Fair Market Value, as defined in this subsection 3.3.1(c), by (y) the Fair Market Value. Solely for purposes of this subsection
3.3.1(c), the “Fair Market Value” shall mean the average reported last sale price of the Common Stock for the five (5) trading days ending on the third trading day prior to the date on which notice of exercise of the
Warrant is sent to the Warrant Agent; or 

  
 11 

 (d) as provided in Section 7.4 hereof. 

3.3.2 Issuance of Shares of Common Stock on Exercise. As soon as practicable after the exercise of any Warrant and the clearance
of the funds in payment of the Exercise Price (if payment is pursuant to subsection 3.3.1(a)), the Company shall issue to the Registered Holder of such Warrant a book-entry position or certificate, as applicable, for the number of full
shares of Common Stock to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as
applicable, for the number of shares of Common Stock as to which such Warrant shall not have been exercised. Notwithstanding the foregoing, the Company shall not be obligated to deliver any shares of Common Stock pursuant to the exercise of a Public
Warrant or a PIPE Financing Warrant and shall have no obligation to settle such Public Warrant or PIPE Financing Warrant exercise unless a registration statement under the Securities Act with respect to the shares of Common Stock underlying the
Public Warrant or PIPE Financing Warrant is then effective and a prospectus relating thereto is current, subject to the Company’s satisfying its obligations under Section 7.4. No Public Warrant or PIPE Financing Warrant shall be
exercisable and the Company shall not be obligated to issue shares of Common Stock upon exercise of a Public Warrant or a PIPE Financing Warrant unless the Common Stock issuable upon such Warrant exercise has been registered, qualified or deemed to
be exempt from registration or qualification under the securities laws of the state of residence of the Registered Holder of the Public Warrants and PIPE Financing Warrants. In the event that the conditions in the two immediately preceding sentences
are not satisfied with respect to a Public Warrant or a PIPE Financing Warrant, the holder of such Warrant shall not be entitled to exercise such Public Warrant or PIPE Financing Warrant, and such Public Warrant or PIPE Financing Warrant may have no
value and expire worthless, in which case the purchaser of a Public Unit containing such Public Warrants shall have paid the full purchase price for the Unit solely for the share of Common Stock underlying such Public Unit. In no event will the
Company be required to net cash settle the Public Warrant or the PIPE Financing Warrant exercise. The Company may require holders of Public Warrants or PIPE Financing Warrants to settle the Public Warrant or PIPE Financing Warrant on a
“cashless basis” pursuant to Section 7.4. If, by reason of any exercise of Warrants on a “cashless basis”, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional
interest in a share of Common Stock, the Company shall round down to the nearest whole number, the number of shares of Common Stock to be issued to such holder.

3.3.3 Valid Issuance. All shares of Common Stock issued upon the proper exercise of a Warrant in conformity with this Agreement
shall be validly issued, fully paid and non-assessable. 
 3.3.4 Date of Issuance. Each
person in whose name any book-entry position or certificate, as applicable, for shares of Common Stock is issued shall for all purposes be deemed to have become the holder of record of such shares of Common Stock on the date on which the Warrant, or
book-entry position representing such Warrant, was surrendered and payment of the Exercise Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Warrant, except that, if the date of such surrender and
payment is a date when the share transfer books of the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed to have become the holder of such shares of Common Stock at the close of business on the next succeeding
date on which the share transfer books or book-entry system are open. 
 3.3.5 Maximum Percentage. A holder of a Warrant may
notify the Company in writing in the event it elects to be subject to the provisions contained in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection 3.3.5 unless he,
she or it makes such election. If the election is made by a holder, the Warrant Agent shall not effect the exercise of the holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the extent that after giving
effect to such exercise, such person (together with such person’s affiliates), to the Warrant Agent’s actual knowledge, would beneficially own in excess of 9.8% (the “Maximum Percentage”) of the shares of Common
Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such person and its affiliates shall include the number of shares of
Common Stock issuable upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock that would be issuable upon (x) exercise of the remaining, unexercised portion
of the Warrant 

  
 12 

 
beneficially owned by such person and its affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by
such person and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in
the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes of
the Warrant, in determining the number of outstanding shares of Common Stock, the holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent annual report on Form 10-K, quarterly report on Form 10-Q, current report on Form 8-K or other public filing with the Commission as the case may be,
(2) a more recent public announcement by the Company or (3) any other notice by the Company or Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written request of the
holder of the Warrant, the Company shall, within two (2) Business Days, confirm orally and in writing to such holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be
determined after giving effect to the conversion or exercise of equity securities of the Company by the holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the
Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder to any other percentage specified in such notice; provided, however, that any such increase shall
not be effective until the sixty-first (61st) day after such notice is delivered to the Company. 
 4. Adjustments. 

4.1 Stock Dividends. 

4.1.1 Split-Ups. If after the date hereof, and subject to the provisions
of Section 4.6 below, the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares of Common Stock or other
similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be increased in proportion to such
increase in the outstanding shares of Common Stock. 
 4.1.2 Extraordinary Dividends. If the Company, at any time while the
Warrants are outstanding and unexpired, shall pay a dividend or make a distribution in cash, securities or other assets to the holders of the Common Stock on account of such shares of Common Stock (or other shares of the Company’s capital stock
into which the Warrants are convertible) (an “Extraordinary Dividend”), then the Exercise Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or
the fair market value (as determined by the Board, in good faith) of any securities or other assets paid on each share of Common Stock in respect of such Extraordinary Dividend; provided, however, that none of the following shall be deemed an
Extraordinary Dividend for purposes of this provision: (a) any adjustment described in subsection 4.1.1 above, (b) any cash dividend or cash distribution which, when combined on a per share basis with the per share amounts of all
other cash dividends and cash distributions paid on the Common Stock during the 365-day period ending on the date of declaration of such dividend or distribution does not exceed $0.50 (as adjusted to
appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends or cash distributions that resulted in an adjustment to the Exercise Price or to the number of shares of Common
Stock issuable on exercise of each Warrant) but only with respect to the amount of the aggregate cash dividend or cash distribution equal to or less than $0.50, (c) any payment to satisfy the redemption rights of the holders of the shares of Common
Stock in connection with a proposed initial Business Combination or (d) any payment in connection with the Company’s liquidation and the distribution of its assets upon its failure to consummate a Business Combination. Solely for purposes
of illustration, if the Company, at a time while the Warrants are outstanding and unexpired, pays a cash dividend of $0.35 and previously paid an aggregate of $0.40 of cash dividends and cash distributions on the Common Stock during the 365-day period ending on the date of declaration of such $0.35 dividend, then the Warrant Price will be decreased, effectively immediately after the effective date of such $0.35 dividend, by $0.25 (the absolute
value of the difference between $0.75 (the aggregate amount of all cash dividends and cash distributions paid or made in such 365-day period, including such $0.35 dividend) and $0.50 (the greater of (x) $0.50
and (y) the aggregate amount of all cash dividends and cash distributions paid or made in such 365-day period prior to such $0.35 dividend)). 

  
 13 

 4.2 Aggregation of Shares. If after the date hereof, and subject to the
provisions of Section 4.6 hereof, the number of outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Common Stock or other similar event, then, on the effective
date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding shares of
Common Stock. 
 4.3 Adjustments in Exercise Price. 

4.3.1 Whenever the number of shares of Common Stock purchasable upon the exercise of the Warrants is adjusted, as provided
in subsection 4.1.1 or Section 4.2 above, the Exercise Price shall be adjusted (to the nearest cent) by multiplying such Exercise Price immediately prior to such adjustment by a fraction (x) the numerator of
which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number of shares of Common Stock so purchasable immediately
thereafter.
 4.3.2 If (a) the Company issues additional shares of Common Stock or equity-linked securities for capital raising
purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.50 per share of Common Stock (with such issue price or effective issue price to be determined in good faith by the
Board, and in the case of any such issuance to Founders or their affiliates, without taking into account any founder shares held by them prior to such issuance), (b) the aggregate gross proceeds from such issuances represent more than 60% of the
total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (c) the volume weighted average trading
price of Common Stock during the 20 trading-day period starting on the trading day prior to the day on which the Company consummates the initial Business Combination (such price, the “Market
Value”) is below $9.50 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the greater of (i) the Market Value or (ii) the price at which the Company issues the
additional shares of Common Stock or equity-linked securities. 
 4.4 Replacement of Securities upon Reorganization, etc. In
case of any reclassification or reorganization of the outstanding shares of Common Stock (other than a change under subsections 4.1.1 or 4.1.2 or Section 4.2 hereof or that solely affects the par value
of such shares of Common Stock), or in the case of any merger or consolidation of the Company with or into another entity or conversion of the Company into another entity (other than a consolidation or merger in which the Company is the continuing
corporation and that does not result in any reclassification or reorganization of the outstanding shares of Common Stock), or in the case of any sale or conveyance to another entity of the assets or other property of the Company as an entirety or
substantially as an entirety in connection with which the Company is dissolved, the holders of the Warrants shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in
lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash)
receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have received if such holder had exercised his, her or its Warrant(s)
immediately prior to such event; and if any reclassification also results in a change in shares of Common Stock covered by Sections 4.1 or 4.2, then such adjustment shall be made pursuant to Sections 4.1, 4.2 and this
Section 4.4. The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. In no event will the Exercise Price be reduced to
less than the par value per share issuable upon exercise of the Warrant. 
 4.5 Notices of Changes in Warrant. Upon every adjustment
of the Exercise Price or the number of shares of Common Stock issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Exercise Price resulting from such adjustment and the
increase or decrease, if any, in the number of shares of Common Stock purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the
occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4, the Company shall give written notice of the occurrence of such event to each holder of a Warrant, at the last address set forth
for such holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event.

  
 14 

 4.6 No Fractional Shares. Notwithstanding any provision contained in this
Agreement to the contrary, the Company shall not issue fractional shares of Common Stock upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon
the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to such holder. 

4.7 Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and
Warrants issued after such adjustment may state the same Exercise Price and the same number of shares of Common Stock as is stated in the Warrants initially issued pursuant to this Agreement; provided, however, that
the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange
or substitution for an outstanding Warrant or otherwise, may be in the form as so changed. 
 4.8 Other Events. In case any
event shall occur affecting the Company as to which none of the provisions of preceding subsections of this Section 4 are strictly applicable, but which would require an adjustment to the terms of the Warrants in order to
(i) avoid an adverse impact on the Warrants and (ii) effectuate the intent and purpose of this Section 4, then, in each such case, the Company shall appoint a firm of independent public accountants, investment banking or other
appraisal firm of recognized national standing, which shall give its opinion as to whether or not any adjustment to the rights represented by the Warrants is necessary to effectuate the intent and purpose of this Section 4 and, if
they determine that an adjustment is necessary, the terms of such adjustment. The Company shall adjust the terms of the Warrants in a manner that is consistent with any adjustment recommended in such opinion. 

5. Transfer and Exchange of Warrants. 

5.1 Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon
the Warrant Register, upon surrender of such Warrant for transfer, in the case of certificated Warrants, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new
Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. In the case of certificated Warrants, the Warrants so cancelled shall be delivered by the Warrant Agent to the
Company from time to time upon request. 
 5.2 Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant
Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal
aggregate number of Warrants; provided, however, that in the event that a Warrant surrendered for transfer bears a restrictive legend (as in the case of the Private Placement Warrants or the PIPE Financing Warrants), the
Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must
also bear a restrictive legend. 
 5.3 Fractional Warrants. The Warrant Agent shall not be required to effect any registration
of transfer or exchange which shall result in the issuance of a warrant certificate or book-entry position for a fraction of a warrant, except as part of the Units. 

5.4 Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants. 

5.5 Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance
with the terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on
behalf of the Company for such purpose. 

  
 15 

 5.6 Transfer of Warrants. Each transfer of a Unit on the register relating to
such Units shall operate also to transfer the Warrants included in such Unit. This Section 5.6 shall not apply to the PIPE Financing Warrants, as they are not issued in conjunction with Units. 

5.7 Transfer of PIPE Financing Warrants to Affiliates. The Subscribers shall be permitted to transfer the PIPE Financing Warrants to
their respective affiliates so long as such affiliates have entered into a written agreement with the Company agreeing to comply with any applicable transfer restrictions under federal and state securities laws in accordance with the provisions of
the Subscription Agreements and this Agreement. 
 6. Redemption. 

6.1 Redemption. Subject to Section 6.4 and Section 6.5 hereof, not less than all of the
outstanding Warrants may be redeemed, at the option of the Company, at any time while they are exercisable and prior to their expiration, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described
in Section 6.2 below, at the price of $0.01 per Warrant (the “Redemption Price”), provided that the last sales price of the Common Stock reported has been at least $18.00 per share (subject to adjustment in
compliance with Section 4 hereof), on each of twenty (20) trading days within the thirty (30) trading-day period ending on the third Business Day prior to the date on
which notice of the redemption is given and provided that there is an effective registration statement covering the shares of Common Stock issuable upon exercise of the Warrants, and a current prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in Section 6.2 below) or the Company has elected to require the exercise of the Warrants on a “cashless basis” pursuant to subsection
3.3.1; provided, however, that if and when the Public Warrants become redeemable by the Company, the Company may not exercise such redemption right if the issuance of shares of Common Stock upon exercise of the Public Warrants is not exempt from
registration or qualification under applicable state blue sky laws or the Company is unable to effect such registration or qualification. 

6.2 Date Fixed for, and Notice of, Redemption. In the event that the Company elects to redeem all of the Warrants, the Company
shall fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (such 30-day period, the “Redemption Period”) to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the registration books. Any notice mailed in
the manner herein provided shall be conclusively presumed to have been duly given whether or not the Registered Holder received such notice. 

6.3 Exercise After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in accordance
with subsection 3.3.1(b) of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.2 hereof and prior to the Redemption Date. In the event that the Company
determines to require all holders of Warrants to exercise their Warrants on a “cashless basis” pursuant to subsection 3.3.1, the notice of redemption shall contain the information necessary to calculate the number of shares of
Common Stock to be received upon exercise of the Warrants, including the Fair Market Value (as such term is defined in subsection 3.3.1(b) hereof) in such case. On and after the Redemption Date, the record holder of the Warrants
shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price. 
 6.4 Exclusion of Private
Placement Warrants. The Company agrees that the redemption rights provided in this Section 6 shall not apply to the Private Placement Warrants if at the time of the redemption such Private Placement Warrants continue to be held
by the Founders and/or their Permitted Transferees. However, once such Private Placement Warrants are transferred (other than to Permitted Transferees under Section 2.6), the Company may redeem the Private Placement Warrants,
provided that the criteria for redemption are met, including the opportunity of the holder of such Private Placement Warrants to exercise the Private Placement Warrants prior to redemption pursuant to Section 6.3. Private Placement
Warrants that are transferred to persons other than Permitted Transferees shall upon such transfer cease to be Private Placement Warrants and shall become Public Warrants under this Agreement. 

  
 16 

 6.5 Exclusion of PIPE Financing Warrants. The Company agrees that the redemption
rights provided in this Section 6 shall not apply to the PIPE Financing Warrants if at the time of the redemption such PIPE Financing Warrants continue to be held, either directly or indirectly through one or more
Participants, by the Subscribers and/or their Permitted Transferees. However, once such PIPE Financing Warrants are transferred, the Company may redeem the PIPE Financing Warrants, provided that the criteria for redemption are met, including the
opportunity of the holder of such PIPE Financing Warrants to exercise the PIPE Financing Warrants prior to redemption pursuant to Section 6.3. PIPE Financing Warrants that are transferred shall upon such transfer cease to
be PIPE Financing Warrants and shall become Public Warrants under this Agreement. Notwithstanding anything to the contrary contained in this Agreement, PIPE Financing Warrants that were originally purchased by a Subscriber shall not be deemed to
have been transferred so long as such PIPE Financing Warrants continue to be held by such Subscriber and/or its Permitted Transferees, in each case directly or indirectly through one or more Participants. 

7. Other Provisions Relating to Rights of Holders of Warrants. 

7.1 No Rights as Stockholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a stockholder of
the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election
of directors of the Company or any other matter. 
 7.2 Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost,
stolen, mutilated, or destroyed, the Company and the Warrant Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new
Warrant of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or
destroyed Warrant shall be at any time enforceable by anyone. 
 7.3 Reservation of Common Stock. The Company shall at all times
reserve and keep available a number of its authorized but unissued shares of Common Stock that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement. 

7.4 Registration of Common Stock; Cashless Exercise at Company’s Option. 

7.4.1 Registration of the Common Stock. The Company agrees that as soon as practicable, but in no event later than fifteen
(15) Business Days after the closing of its initial Business Combination, it shall use its best efforts to file with the Commission a registration statement for the registration, under the Securities Act, of the shares of Common Stock issuable
upon exercise of the Warrants. The Company shall use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the
Warrants in accordance with the provisions of this Agreement. If any such registration statement has not been declared effective by the 60th Business Day following the closing of the Business Combination, holders of the Warrants shall have the
right, during the period beginning on the 61st Business Day after the closing of the Business Combination and ending upon such registration statement being declared effective by the Commission, and during any other period when the Company shall fail
to have maintained an effective registration statement covering the shares of Common Stock issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless basis,” by exchanging the Warrants (in accordance with
Section 3(a)(9) of the Securities Act (or any successor rule) or another exemption) for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the
Warrants, multiplied by the difference between the Exercise Price and the Fair Market Value (as defined below) by (y) the Fair Market Value. Solely for purposes of this subsection 7.4.1, “Fair Market Value”
shall mean the volume weighted average price of the Common Stock as reported during the five (5) trading day period ending on the trading day prior to the date that notice of exercise is received by the Warrant Agent from the holder of such
Warrants or its securities broker or intermediary. The date that notice of cashless exercise is received by the Warrant Agent shall be conclusively determined by the Warrant Agent. In connection with the “cashless exercise” of a Public
Warrant or a PIPE Financing Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion of counsel for the Company (which shall be an outside law firm with securities law experience) stating that (i) the exercise of the
Warrants on a cashless basis in accordance with this subsection 7.4.1 is not required to be registered under the Securities Act and (ii) the shares of Common Stock issued upon such exercise shall be freely tradable

  
 17 

 
under United States federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Securities Act (or any successor rule)) of the Company and,
accordingly, shall not be required to bear a restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of any doubt, unless and until all of the Warrants have been exercised, the Company shall continue to be obligated
to comply with its registration obligations under the first three sentences of this subsection 7.4.1. 
 7.4.2 Cashless
Exercise at Company’s Option. If the Common Stock is at the time of any exercise of a Warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1)
of the Securities Act (or any successor rule), the Company may, at its option, (i) require holders of Public Warrants or PIPE Financing Warrants who exercise Public Warrants or PIPE Financing Warrants to exercise such Public Warrants or PIPE
Financing Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act (or any successor rule) as described in subsection 7.4.1 and (ii) in the event the Company so elects, the Company
shall not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the Common Stock issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary. If
the Company does not elect at the time of exercise to require a holder of Public Warrants or PIPE Financing Warrants who exercises Public Warrants or PIPE Financing Warrants to exercise such Public Warrants or PIPE Financing Warrants on a
“cashless basis,” it agrees to use its best efforts to register or qualify for sale the Common Stock issuable upon exercise of the Public Warrant or PIPE Financing Warrant under the blue sky laws of the state of residence in those states
in which the Public Warrants or PIPE Financing Warrants were initially offered by the Company of the exercising Public Warrant or PIPE Financing Warrant holder to the extent an exemption is not available. 

8. Concerning the Warrant Agent and Other Matters. 

8.1 Payment of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company
or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares of Common Stock. 

8.2 Resignation, Consolidation, or Merger of Warrant Agent. 

8.2.1 Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its
duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise,
the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or
incapacity by the Warrant Agent or by the holder of a Warrant (who shall, with such notice, submit his Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of
New York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of New
York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state
authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent
hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent
all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and
effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations. 

8.2.2 Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice
thereof to the predecessor Warrant Agent and the Transfer Agent for the Common Stock not later than the effective date of any such appointment. 

  
 18 

 8.2.3 Merger or Consolidation of Warrant Agent. Any corporation into which the
Warrant Agent may be merged or with which it may be consolidated or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further
act. 
 8.3 Fees and Expenses of Warrant Agent. 

8.3.1 Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent
hereunder and shall, pursuant to its obligations under this Agreement, reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder. 

8.3.2 Further Assurances. The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed, executed,
acknowledged, and delivered all such further and other acts, instruments, and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement. 

8.4 Liability of Warrant Agent. 

8.4.1 Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem
it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be
deemed to be conclusively proved and established by a statement signed by the President, Chief Executive Officer or Chairman of the Board of the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any
action taken or suffered in good faith by it pursuant to the provisions of this Agreement. 
 8.4.2 Indemnity. The Warrant
Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith. The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and reasonable
counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s gross negligence, willful misconduct or bad faith. 

8.4.3 Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect
to the validity or execution of any Warrant (except its countersignature thereof). The Warrant Agent shall not be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant. The Warrant Agent
shall not be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that would
require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be issued pursuant to this Agreement or any Warrant or as to
whether any shares of Common Stock shall, when issued, be valid and fully paid and non-assessable. 

8.5 Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same
upon the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the
purchase of shares of Common Stock through the exercise of the Warrants. 
 8.6 Waiver. The Warrant Agent has no right of set-off or any other right, title, interest or claim of any kind (“Claim”) in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement,
dated as of the date hereof, by and between the Company and the Warrant Agent as trustee thereunder) and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason whatsoever.
The Warrant Agent hereby waives any and all Claims against the Trust Account and any and all rights to seek access to the Trust Account. 

  
 19

Certificate 
 This Warrant Certificate certifies that             ,

(“Common Stock”), of GigCapital2, Inc., a Delaware corporation (the “Company”). Each Warrant entitles the holder, upon exercise during the period set forth in the
Warrant Agreement referred to below, to receive from the Company that number of fully paid and non-assessable shares of Common Stock as set forth below, at the exercise price
(the “Exercise Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless exercise” as provided for in the Warrant Agreement) of the
United States of America upon surrender of this Warrant Certificate and payment of the Exercise Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement. Defined
terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement. 
 Each
Warrant is initially exercisable for one fully paid and non-assessable share of Common Stock. The number of shares of Common Stock issuable upon exercise of the Warrants is subject to adjustment upon the
occurrence of certain events set forth in the Warrant Agreement. 
 The initial Exercise Price per share of Common Stock for any Warrant is
equal to $11.50 per share. The Exercise Price is subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement. 

Subject to the conditions set forth in the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent
not exercised by the end of such Exercise Period, such Warrants shall become void. 
 Reference is hereby made to the further provisions of
this Warrant Certificate set forth on the reverse hereof and such further provisions shall for all purposes have the same effect as though fully set forth at this place. 

This Warrant Certificate shall not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement. 

This Warrant Certificate shall be governed by and construed in accordance with the internal laws of the State of New York, without regard to
conflicts of laws principles thereof.

The Warrants evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive
shares of Common Stock and are issued or to be issued pursuant to an Amended and Restated Warrant Agreement dated as of June 9, 2021 (the “Warrant Agreement”), duly executed and delivered by the
Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part
of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the
words “holders” or “holder” meaning the Registered Holders or Registered Holder) of the Warrants. A copy of the Warrant Agreement may be obtained by the
holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement. 

Warrants may be exercised at any time during the Exercise Period set forth in the Warrant Agreement. The holder of Warrants evidenced by this
Warrant Certificate may exercise them by surrendering this Warrant Certificate, with the form of election to purchase set forth hereon properly completed and executed, together with payment of the Exercise Price as specified in the Warrant Agreement
(or through “cashless exercise” as provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised shall
be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised. 

Notwithstanding anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise
(i) a registration statement covering the shares of Common Stock to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the shares of Common Stock is current, except through
“cashless exercise” as provided for in the Warrant Agreement. 
 The Warrant Agreement provides that upon the occurrence of
certain events the number of shares of Common Stock issuable upon exercise of the Warrants set forth on the face hereof may, subject to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive
a fractional interest in a share of Common Stock, the Company shall, upon exercise, round down to the nearest whole number of shares of Common Stock to be issued to the holder of the Warrant. 

Warrant Certificates, when surrendered at the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person
or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or
Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants. 

 Upon due presentation for registration of transfer of this Warrant Certificate at the office
of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations
provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith. 
 The
Company and the Warrant Agent may deem and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise
hereof, of any distribution to the holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants nor this Warrant Certificate entitles any holder
hereof to any rights of a stockholder of the Company. 
 Election to Purchase 

(To Be Executed Upon Exercise of Warrant) 

The undersigned hereby irrevocably elects to exercise the right, represented by this Warrant Certificate, to receive
                shares of Common Stock and herewith tenders payment for such shares of Common Stock to the order of GigCapital2, Inc.
(the “Company”) in the amount of $                in accordance with the terms hereof. The undersigned requests that a
certificate for such shares of Common Stock be registered in the name of                 , whose address is
                and that such shares of Common Stock be delivered to
                whose address is                 . If said number of shares of Common
Stock is less than all of the shares of Common Stock purchasable hereunder, the undersigned requests that a new Warrant Certificate representing the remaining balance of such shares of Common Stock be registered in the name of
                , whose address is                 and that such Warrant Certificate be
delivered to                 , whose address is                 . 

In the event that the Warrant has been called for redemption by the Company pursuant to Section 6 of the
Warrant Agreement and the Company has required cashless exercise pursuant to Section 6.3 of the Warrant Agreement, the number of shares of Common Stock that this Warrant is exercisable for shall be determined in
accordance with subsection 3.3.1(b) and Section 6.3 of the Warrant Agreement. 
 In the
event that the Warrant is a Private Placement Warrant that is to be exercised on a “cashless” basis pursuant to subsection 3.3.1(c) of the Warrant Agreement, the number of shares of Common Stock that this Warrant is
exercisable for shall be determined in accordance with subsection 3.3.1(c) of the Warrant Agreement. 
 In the event that
the Warrant is to be exercised on a “cashless” basis pursuant to Section 7.4 of the Warrant Agreement, the number of shares of Common Stock that this Warrant is exercisable for shall be determined in
accordance with Section 7.4 of the Warrant Agreement. 
 In the event that the Warrant may be exercised, to
the extent allowed by the Warrant Agreement, through cashless exercise (i) the number of shares of Common Stock that this Warrant is exercisable for would be determined in accordance with the relevant section of the Warrant Agreement which
allows for such cashless exercise and (ii) the holder hereof shall complete the following: The undersigned hereby irrevocably elects to exercise the right, represented by this Warrant Certificate, through the cashless exercise provisions of the
Warrant Agreement, to receive shares of Common Stock. If said number of shares is less than all of the shares of Common Stock purchasable hereunder (after giving effect to the cashless exercise), the undersigned requests that a new Warrant
Certificate representing the remaining balance of such shares of Common Stock be registered in the name of                 , whose address is
                and that such Warrant Certificate be delivered to                 , whose
address is                 .
