FORM OF BACKSTOP SUBSCRIPTION
AGREEMENT

 

This BACKSTOP SUBSCRIPTION
AGREEMENT (this “Backstop Subscription Agreement”) is entered into on October 13, 2021, by and between ACE Convergence
Acquisition Corp., a Cayman Islands exempted company (“Issuer”), and the undersigned subscriber (the “Backstop
Investor”).

 

WHEREAS, this Backstop Subscription
Agreement is being entered into in connection with the Agreement and Plan of Merger, dated as of the date hereof (as may be amended, supplemented
or otherwise modified from time to time, the “Transaction Agreement”), by and among Issuer, Tempo Automation, Inc.,
a Delaware corporation (the “Company”), ACE Convergence Subsidiary Corp., a Delaware corporation and a direct wholly
owned subsidiary of Issuer (“Merger Sub”), and the other parties thereto, pursuant to which, among other things, Merger
Sub will merge with and into the Company, with the Company surviving such merger as a wholly owned subsidiary of Issuer (collectively,
the “Transaction”);

 

WHEREAS, prior to the closing
of the Transaction (and as more fully described in the Transaction Agreement), Issuer will domesticate as a Delaware corporation in accordance
with Section 388 of the General Corporation Law of the State of Delaware and Part XII of the Cayman Islands Companies Law (2020 Revision)
(the “Domestication”);

 

WHEREAS,
in connection with the Transaction, and subject to the limitations set forth in Section 1 hereof, Issuer is
seeking the commitment from the Backstop Investor to purchase, following the Domestication and substantially concurrently with the closing
of the Transaction, shares of Issuer’s common stock, par value $0.001 per share, as such shares will exist as common stock following
the Domestication (the “Backstop Shares”), in a private placement for a purchase price of $10.00 per share (the “Per
Share Subscription Price”) to backstop certain redemptions by Company shareholders;

 

WHEREAS,
the aggregate purchase price to be paid by the Backstop Investor for the subscribed Backstop Shares pursuant to Section 1
hereof is referred to herein as the “Subscription Amount”; and

 

WHEREAS, substantially concurrently
with the execution of this Backstop Subscription Agreement, Issuer is entering into separate subscription agreements (collectively, the
 “Other Subscription Agreements”) with certain other investors (the “Other Investors”) (other than
pursuant to this Backstop Subscription Agreement) with an aggregate purchase price of $107,000,000.

 

NOW, THEREFORE, in consideration
of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, set forth herein, and intending
to be legally bound hereby, each of the Backstop Investor and Issuer acknowledges and agrees as follows:

 

1.                  
Subscription. Subject to the terms and conditions set forth in this Backstop Subscription Agreement, in the event that any
holder of the Issuer’s ordinary shares, contemporaneously with or prior to the vote of the Issuer’s shareholders in the extraordinary
general meeting of the Issuer to approve the Transaction, elects to have such holder’s ordinary shares redeemed by the Issuer, then,
if immediately prior to the consummation of the Transaction: (a) the PIPE Investment Amount (as defined in the Transaction Agreement)
actually received by Acquiror prior to or substantially concurrently with the Closing equals or exceeds $107,000,000; (b) the Available
Credit Amount (as defined in the Transaction Agreement) equals or exceeds $52,000,000; and (c) the condition precedent to the closing
of the Transaction set forth in Section 9.3(d) of the Transaction Agreement (the “Minimum Cash Condition”) would
not be satisfied if the Subscription Amount were equal to $0 (the amount of additional cash required to satisfy the Minimum Cash Condition,
the “Cash Shortfall Amount”), the Backstop Investor hereby irrevocably subscribes for and agrees to purchase from the
Issuer, at the Per Share Subscription Price, the number of Backstop Shares equal to the quotient of (x) the lesser of (A) the Cash
Shortfall Amount and (B) $25,000,000 divided by (y) $10.00, with such number of Backstop Shares to be rounded up to the nearest whole
number, and the Issuer agrees to sell such Backstop Shares to the Backstop Investor at the Per Share Subscription Price. The Backstop
Investor acknowledges and agrees that, as a result of the Domestication, the Backstop Shares that will be issued pursuant hereto shall
be shares of common stock in a Delaware corporation (and not shares in a Cayman Islands exempted company).

 

    

     

    

 

2.                  
Closing. The closing of the sale of the Backstop Shares contemplated hereby (the “Closing”) shall occur
on the closing date (the “Closing Date”) and is expected to occur substantially concurrent with the consummation of
the Transaction. Subject to the satisfaction or waiver of the conditions set forth in this Section 2 and in Section 3
below, upon delivery of written notice from (or on behalf of) Issuer to the Backstop Investor (the “Closing Notice”),
that Issuer reasonably expects all conditions to the closing of the Transaction to be satisfied or waived on an expected Closing Date
that is not less than ten (10) business days from the date on which the Closing Notice is delivered to the Backstop Investor, the Backstop
Investor shall deliver to Issuer, on the expected Closing Date specified in the Closing Notice, the Subscription Amount by wire transfer
of United States dollars in immediately available funds to the account(s) specified by Issuer in the Closing Notice. On the Closing Date
and prior to the release of the Subscription Amount by the Backstop Investor, Issuer shall issue the Backstop Shares against payment of
the Subscription Amount to the Backstop Investor and cause the Backstop Shares to be registered in book entry form in the name of the
Backstop Investor on Issuer’s share register (which book entry records shall contain an appropriate notation concerning transfer
restrictions of the Backstop Shares, in accordance with applicable securities laws of the states of the United States and other applicable
jurisdictions), and will provide to the Backstop Investor evidence of such issuance from Issuer’s transfer agent. For purposes of
this Backstop Subscription Agreement, “business day” shall mean a day, other than a Saturday, Sunday or other day on
which commercial banks in New York, New York or governmental authorities in the Cayman Islands (for so long as Issuer remains domiciled
in Cayman Islands) are authorized or required by law to close. Prior to or at the Closing, Backstop Investor shall deliver to Issuer a
duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8. In the event the consummation of the Transaction
does not occur within two (2) business days after the Closing Date under this Backstop Subscription Agreement, Issuer shall promptly (but
not later than two (2) business days thereafter) return the Subscription Amount to the Backstop Investor by wire transfer of U.S.
dollars in immediately available funds to the account specified by the Backstop Investor, and any book entries for the Backstop Shares
shall be deemed repurchased and cancelled; provided that, unless this Backstop Subscription Agreement has been terminated pursuant
to Section 8 hereof, such return of funds shall not terminate this Backstop Subscription Agreement or relieve the Backstop
Investor of its obligation to purchase the Backstop Shares at the Closing.

 

3.                  
Closing Conditions. The obligation of the parties hereto to consummate the purchase and sale of the Backstop Shares pursuant

enjoining or prohibiting the issuance and sale of the Backstop Shares under this Backstop Subscription Agreement; (b) all conditions precedent
to the closing of the Transaction under the Transaction Agreement shall have been satisfied or waived (as determined by the parties to
the Transaction Agreement and other than those conditions under the Transaction Agreement which, by their nature, are to be fulfilled
at or substantially contemporaneously with the closing of the Transaction); (c)(i) solely with respect to the Backstop Investor’s
obligation to close, the representations and warranties made by Issuer, and (ii) solely with respect to Issuer’s obligation to close,
the representations and warranties made by the Backstop Investor, in each case, in this Backstop Subscription Agreement shall be true
and correct in all material respects as of the Closing Date other than (x) those representations and warranties which are qualified by
materiality, Material Adverse Effect or similar qualification, which shall be true and correct in all respects as of the Closing Date,
and (y) those representations and warranties expressly made as of an earlier date, which shall be true and correct in all material respects
(or, if qualified by materiality, Material Adverse Effect or similar qualification, all respects) as of such date, in each case without
giving effect to the consummation of the Transactions; and (d)(i) solely with respect to the Backstop Investor’s obligation to purchase
the Backstop Shares pursuant to this Backstop Subscription Agreement, Issuer shall have performed, satisfied and complied in all material
respects with all covenants, agreements and conditions required by this Backstop Subscription Agreement to be performed, satisfied or
complied with by it at or prior to the Closing, and (ii) solely with respect to the Issuer’s obligation to close, the Backstop Investor
shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required by this Backstop
Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing.

 

4.

additional actions as the parties reasonably may deem to be practical and necessary in order to consummate the subscription as contemplated
by this Backstop Subscription Agreement.

indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Issuer or any of its subsidiaries

Shares or the legal authority of Issuer to comply in all material respects with its obligations under this Backstop Subscription Agreement;
(ii) result in any violation of the provisions of the organizational documents of Issuer; or (iii) result in any violation of

As of the date hereof, Issuer has not received any written communication from a governmental authority that alleges that Issuer
is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation
would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(a)                
The Backstop Investor (i) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or

for its own account and not for the account of others, or if the Backstop Investor is subscribing for the Backstop Shares as a fiduciary
or agent for one or more investor accounts, the Backstop Investor has full investment discretion with respect to each such account, and
the full power and authority to make the acknowledgements, representations and agreements herein on behalf of each owner of each such

The Backstop Investor is a sophisticated investor, experienced in investing in private equity transactions and capable of evaluating
investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or

and together with Citi, the “Placement Agents” and individually, a “Placement Agent”) or any of
their respective affiliates, or any control persons, officers, directors, employees, agents or representatives of any of the foregoing.
Accordingly, the Backstop Investor understands that the offering meets (i) the exemptions from filing under FINRA Rule 5123(b)(1)(A) and
(ii) the institutional customer exemption under FINRA Rule 2111(b). The Backstop Investor has determined based on its own independent
review and such professional advice as it deems appropriate that the Backstop Investor’s purchase of the Backstop Shares and participation
in the Transaction (A) are fully consistent with its financial needs, objectives and condition, (B) comply and are fully consistent with
all investment policies, guidelines and other restrictions applicable to it, (C) have been duly authorized and approved by all necessary
action, (D) do not and will not violate or constitute a default under the Backstop Investor’s charter, by-laws or other constituent
document or under any law, rule, regulation, agreement or other obligation by which it is bound and (E) are a fit, proper and suitable

and that any certificates or book entry records representing the Backstop Shares shall contain a restrictive legend to such effect. The

that certain information received was based on projections, and such projections were prepared based on assumptions and estimates that

information and projections were prepared without the participation of the Placement Agents and that the Placement Agents do not assume
responsibility for independent verification of, or the accuracy or completeness of, such information or projections. Without limiting
the generality of the foregoing, the Backstop Investor acknowledges that it has reviewed Issuer’s filings with the SEC. The Backstop

of 2001 (the “PATRIOT Act”), and its implementing regulations (collectively, the “BSA/PATRIOT Act”),
that the Backstop Investor maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT
Act. The Backstop Investor also represents that it maintains policies and procedures reasonably designed to ensure compliance with sanctions
administered by the United States, the European Union, or any individual European Union member state, including the United Kingdom, to
the extent applicable to it. The Backstop Investor further represents that the funds held by the Backstop Investor and used to purchase
the Backstop Shares were legally derived and were not obtained, directly or indirectly, from a Prohibited Investor.

or to any person claiming through the Backstop Investor, in respect of the Transaction.

 

(r)                 
In connection with the issue and purchase of the Backstop Shares, the Placement Agents are acting solely as placement agents to

Investor hereby waives, to the fullest extent permitted by law, any claims it may have based on any actual or potential conflict of interest
or similar claim, whether known or unknown, contingent or otherwise and wherever and whenever arising in connection with, relating to

7.             
Registration Rights.

 

(a)                
Issuer agrees that, within thirty (30) business days following the Closing Date (such deadline, the “Filing Deadline”),
Issuer will submit to or file with the SEC a registration statement for a shelf registration on Form S-1 or Form S-3 (if Issuer is then
eligible to use a Form S-3 shelf registration) (the “Registration Statement”), in each case, covering the resale of
the Backstop Shares acquired by the Backstop Investor pursuant to this Backstop Subscription Agreement which are eligible for registration
(determined as of two business days prior to such submission or filing) (the “Registrable Backstop Shares”) and Issuer
shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing
thereof, but no later than the earlier of (i) the 120th calendar day following the filing date thereof if the SEC notifies Issuer
that it will “review” the Registration Statement (including a limited review) and (ii) the 10th business day after the
date Issuer is notified (orally or in writing, whichever is earlier) by the SEC that the Registration Statement will not be “reviewed”
or will not be subject to further review (such earlier date, the “Effectiveness Deadline”); provided, however,
that Issuer’s obligations to include the Registrable Backstop Shares in the Registration Statement are contingent upon Backstop
Investor furnishing in writing to Issuer such information regarding Backstop Investor or its permitted assigns, the securities of Issuer
held by Backstop Investor and the intended method of disposition of the Registrable Backstop Shares (which shall be limited to non-underwritten
public offerings) as shall be reasonably requested by Issuer to effect the registration of the Registrable Backstop Shares at least five
(5) business days in advance of the expected filing date of the Registration Statement, and Backstop Investor shall execute such documents
in connection with such registration as Issuer may reasonably request that are customary of a selling stockholder in similar situations,
including providing that Issuer shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement, if applicable,
during any customary blackout or similar period or as permitted hereunder; provided that Backstop Investor shall not in connection
with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the
ability to transfer the Registrable Backstop Shares. Notwithstanding the foregoing, if the SEC prevents Issuer from including any or all
of the shares proposed to be registered under a Registration Statement due to limitations on the use of Rule 415 under the Securities
Act for the resale of the Shares pursuant to this Section 7 by the applicable stockholders or otherwise, such Registration Statement shall
register for resale such number of Shares which is equal to the maximum number of Shares as is permitted to be registered by the SEC.
In such event, the number of Shares to be registered for each selling stockholder named in such Registration Statement shall be reduced
pro rata among all such selling stockholders. In the event Issuer amends the Registration Statement in accordance with the foregoing,
Issuer will use its commercially reasonable efforts to file with the SEC, as promptly as allowed by the SEC, one or more registration
statements to register the resale of those Registrable Shares that were not registered on the initial Registration Statement, as so amended.
For as long as the Backstop Investor holds Backstop Shares, Issuer will use commercially reasonable efforts to file all reports for so
long as the condition in Rule 144(c)(1) (or Rule 144(i)(2), if applicable) is required to be satisfied, and provide all customary and
reasonable cooperation, necessary to enable the undersigned to resell the Backstop Shares pursuant to Rule 144 of the Securities Act (in
each case, when Rule 144 of the Securities Act becomes available to the Backstop Investor). Any failure by Issuer to file the Registration
Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Deadline shall not otherwise relieve Issuer
of its obligations to file or effect the Registration Statement as set forth above in this Section 7.

 

(b)          
At its expense Issuer shall:

 

(i)                 
except for such times as Issuer is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement,
use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities
laws which Issuer determines to obtain, continuously effective with respect to Backstop Investor, and to keep the applicable Registration
Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of the following:
(A) Backstop Investor ceases to hold any Registrable Backstop Shares, (B) the date all Registrable Backstop Shares held by Backstop
Investor may be sold without restriction under Rule 144, including, without limitation, any volume and manner of sale restrictions which
may be applicable to affiliates under Rule 144 and without the requirement for Issuer to be in compliance with the current public information
required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), and (C) two (2) years from the date of effectiveness of the Registration
Statement (the period of time during which Issuer is required hereunder to keep a Registration Statement effective is referred to herein
as the “Registration Period”);

 

    9

     

    

 

(ii)               
during the Registration Period, advise Backstop Investor, as expeditiously as practicable:

 

(1)               
when a Registration Statement or any amendment thereto has been filed with the SEC;

 

(2)               
after it shall receive notice or obtain knowledge thereof, of the issuance by the SEC of any stop order suspending the effectiveness
of any Registration Statement or the initiation of any proceedings for such purpose;

 

(3)               
of the receipt by Issuer of any notification with respect to the suspension of the qualification of the Registrable Backstop Shares
included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

 

(4)               
subject to the provisions in this Backstop Subscription Agreement, of the occurrence of any event that requires the making of any
changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit
to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the
light of the circumstances under which they were made) not misleading.

 

Notwithstanding anything to the contrary set forth
herein, Issuer shall not, when so advising Backstop Investor of such events, provide Backstop Investor with any material, nonpublic information
regarding Issuer other than to the extent that providing notice to Backstop Investor of the occurrence of the events listed in (1) through
(4) above constitutes material, nonpublic information regarding Issuer;

 

(iii)             
during the Registration Period, use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness
of any Registration Statement as soon as reasonably practicable;

 

(iv)            
during the Registration Period, upon the occurrence of any event contemplated in Section 7(b)(ii)(4) above, except
for such times as Issuer is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration
Statement, Issuer shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment
to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered
to purchasers of the Registrable Backstop Shares included therein, such prospectus will not include any untrue statement of a material
fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were
made, not misleading;

 

(v)               
during the Registration Period, use its commercially reasonable efforts to cause all Registrable Backstop Shares to be listed on
each securities exchange or market, if any, on which the shares of common stock issued by Issuer have been listed;

 

(vi)              
during the Registration Period, use its commercially reasonable efforts to allow the Backstop Investor to review disclosure regarding
the Backstop Investor in the Registration Statement; and

 

(vii)            
during the Registration Period, otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably
be requested by the Backstop Investor, consistent with the terms of this Backstop Subscription Agreement, in connection with the registration
of the Registrable Backstop Shares.

 

    10

     

    

 

(c)                
Notwithstanding anything to the contrary in this Backstop Subscription Agreement, Issuer shall be entitled to delay the filing
or effectiveness of, or suspend the use of, the Registration Statement if it determines that in order for the Registration Statement not
to contain a material misstatement or omission, (i) an amendment thereto would be needed to include information that would at that time
not otherwise be required in a current, quarterly, or annual report under the Exchange Act, (ii) the negotiation or consummation of a
transaction by Issuer or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event Issuer’s
board of directors reasonably believes would require additional disclosure by Issuer in the Registration Statement of material information
that Issuer has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would
be expected, in the reasonable determination of Issuer’s board of directors to cause the Registration Statement to fail to comply
with applicable disclosure requirements, or (iii) in the good faith judgment of the majority of the members of Issuer’s board of
directors, such filing or effectiveness or use of such Registration Statement, would be seriously detrimental to Issuer and the majority
of the members of Issuer’s board of directors concludes as a result that it is essential to defer such filing (each such circumstance,
a “Suspension Event”); provided, however, that Issuer may not delay or suspend the Registration Statement
on more than three occasions or for more than ninety (90) consecutive calendar days, or more than one hundred and twenty (120) total
calendar days in each case during any twelve-month period. Upon receipt of any written notice from Issuer of the happening of any Suspension
Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement
or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein (in light of the circumstances under which they were made, in the case of the prospectus)
not misleading, Backstop Investor agrees that (i) it will immediately discontinue offers and sales of the Registrable Backstop Shares
under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until Backstop Investor
receives copies of a supplemental or amended prospectus (which Issuer agrees to promptly prepare) that corrects the misstatement(s) or
omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified
by Issuer that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in
such written notice delivered by Issuer unless otherwise required by law or subpoena. If so directed by Issuer, Backstop Investor will
deliver to Issuer or, in Backstop Investor’s sole discretion destroy, all copies of the prospectus covering the Registrable Backstop
Shares in Backstop Investor’s possession; provided, however, that this obligation to deliver or destroy all copies
of the prospectus covering the Registrable Backstop Shares shall not apply (A) to the extent Backstop Investor is required to retain
a copy of such prospectus (1) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements
or (2) in accordance with a bona fide pre-existing document retention policy or (B) to copies stored electronically on archival
servers as a result of automatic data back-up.

 

(d)               
Indemnification.

 

(i)                 
Issuer agrees to indemnify, to the extent permitted by law, Backstop Investor (to the extent a seller under the Registration Statement),
its directors and officers and each person who controls Backstop Investor (within the meaning of the Securities Act or the Exchange Act),
to the extent permitted by law, against all losses, claims, damages, liabilities and reasonable and documented out of pocket expenses
(including reasonable and documented outside attorneys’ fees of one law firm (and one firm of local counsel)) caused by any untrue
or alleged untrue statement of material fact contained in any Registration Statement, prospectus included in any Registration Statement
(“Prospectus”) or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged
omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, in
the light of the circumstances under which they were made) not misleading, except insofar as the same are caused by or contained in any
information or affidavit so furnished in writing to Issuer by or on behalf of Backstop Investor expressly for use therein.

 

    11

     

    

 

(ii)               
In connection with any Registration Statement in which Backstop Investor is participating, Backstop Investor shall furnish (or
cause to be furnished) to Issuer in writing such information and affidavits as Issuer reasonably requests for use in connection with any
such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify Issuer, its directors and officers and
each person or entity who controls Issuer (within the meaning of the Securities Act or the Exchange Act) against any losses, claims, damages,
liabilities and expenses (including, without limitation, reasonable outside attorneys’ fees) resulting from any untrue or alleged
untrue statement of material fact contained or incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus
or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of a Prospectus, in the light of the circumstances under which they were made) not
misleading, but only to the extent that such untrue statement or omission is contained (or not contained in, in the case of an omission)
in any information or affidavit so furnished in writing by on behalf of Backstop Investor expressly for use therein; provided,
however, that the liability of Backstop Investor shall be several and not joint with any Other Investor and shall be in proportion
to and limited to the net proceeds received by Backstop Investor from the sale of Registrable Backstop Shares giving rise to such indemnification
obligation.

 

(iii)             
Any person or entity entitled to indemnification herein shall (A) 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
or entity’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (B) 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 includes a statement or admission of fault and culpability on the part of such indemnified party
or which 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. 

 

(iv)              
The indemnification provided for under this Backstop Subscription 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 or entity of such indemnified
party and shall survive the transfer of securities. 

 

(v)               
If the indemnification provided under this Section 7(d) 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; provided, however,
that the liability of the Backstop Investor shall be limited to the net proceeds received by Backstop Investor from the sale of Registrable
Backstop Shares giving rise to such indemnification obligation. 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 not made by, in the case of an omission), or
relates to information supplied by (or not supplied by, in the case of an omission), 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. 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 7(d)(i), (ii) and (iii) above, any legal
or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. 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 7(d)(v) from any person or entity who was not guilty of such fraudulent misrepresentation.

 

    12

     

    

 

8.                  
Termination. This Backstop Subscription Agreement shall terminate and be void and of no further force and effect, and all
rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof,
upon the earliest to occur of (a) such date and time as the Transaction Agreement is terminated in accordance with its terms without
being consummated, (b) upon the mutual written agreement of each of the parties hereto to terminate this Backstop Subscription Agreement,
(c) if the conditions to Closing set forth in Section 3 of this Backstop Subscription Agreement are not satisfied, or
are not capable of being satisfied, on or prior to the Closing and, as a result thereof, the transactions contemplated by this Backstop
Subscription Agreement will not be or are not consummated at the Closing and (iv)the Agreement End Date (as defined in the Transaction
Agreement and as it may be extended as described therein) if the Closing has not occurred by such date; provided that nothing herein
will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled
to any remedies at law or in equity to recover losses, liabilities or damages arising from any such willful breach. Issuer shall notify
the Backstop Investor of the termination of the Transaction Agreement promptly after the termination of such agreement. Upon the termination
of this Backstop Subscription Agreement in accordance with this Section 8, any monies paid by the Backstop Investor to Issuer
in connection herewith shall be promptly (and in any event within one business day after such termination) returned to the Backstop Investor.

 

9.                  
Backstop Investor Covenant. Backstop Investor hereby agrees that, from the date of this Backstop Subscription Agreement,
none of Backstop Investor, its controlled affiliates, or any person or entity acting on behalf of Backstop Investor or any of its controlled
affiliates or pursuant to any understanding with Backstop Investor or any of its controlled affiliates will engage in any Short Sales
with respect to securities of Issuer prior to the Closing Date. For purposes of this Section 9, “Short Sales”
shall include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange
Act, and all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage
arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and sales
and other transactions through non-U.S. broker dealers or foreign regulated brokers. Notwithstanding the foregoing, (i) nothing herein
shall prohibit other entities under common management with Backstop Investor that have no knowledge of this Backstop Subscription Agreement
or of Backstop Investor’s participation in the Transaction (including Backstop Investor’s controlled affiliates and/or affiliates)
from entering into any Short Sales and (ii) if Backstop Investor is a multi-managed investment vehicle whereby separate portfolio managers
manage separate portions of Backstop Investor’s assets and the portfolio managers have no knowledge of the investment decisions
made by the portfolio managers managing other portions of Backstop Investor’s assets, the covenant set forth above shall only apply
with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Backstop Shares
covered by this Backstop Subscription Agreement.

 

    13

     

    

 

10.               
Trust Account Waiver. The Backstop Investor acknowledges that Issuer is a blank check company with the powers and privileges
to effect a merger, asset acquisition, reorganization or similar business combination involving Issuer and one or more businesses or assets.
The Backstop Investor further acknowledges that, as described in Issuer’s prospectus relating to its initial public offering dated
July 27, 2020 (the “IPO Prospectus”) available at www.sec.gov, substantially all of Issuer’s assets consist of
the cash proceeds of Issuer’s initial public offering and private placement of its securities, and substantially all of those proceeds
have been deposited in a trust account (the “Trust Account”) for the benefit of Issuer, its public shareholders and
the underwriter of Issuer’s initial public offering. Except with respect to interest earned on the funds held in the Trust Account
that may be released to Issuer to pay its tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes
set forth in the IPO Prospectus. For and in consideration of Issuer entering into this Backstop Subscription Agreement, the receipt and
sufficiency of which are hereby acknowledged, the Backstop Investor hereby irrevocably waives any and all right, title and interest, or
any claim of any kind it has or may have in the future, in or to any monies held in the Trust Account, and irrevocably agrees not to seek
recourse against the Trust Account as a result of, or arising out of, this Backstop Subscription Agreement. Backstop Investor agrees and
acknowledges that such irrevocable waiver is material to this Backstop Subscription Agreement and specifically relied upon by Issuer and
its affiliates to induce Issuer to enter in this Backstop Subscription Agreement, and each such party further intends and understands
such waiver to be valid, binding and enforceable against the Backstop Investor and its affiliates under applicable law. To the extent
Backstop Investor commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating
to Issuer or its affiliates, which proceeding seeks, in whole or in part, monetary relief against Issuer or its affiliates, the Backstop
Investor hereby acknowledges and agrees that the Backstop Investor’s sole remedy shall be against funds held outside of the Trust
Account and that such claim shall not permit the Backstop Investor (or any person claiming on any of their behalves or in lieu of any
of the Backstop Investor) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained
therein and in the event of any action or proceeding based upon, in connection with, relating to or arising out of any matter relating
to Issuer or its affiliates, which proceeding seeks, in whole or in part, relief against the Trust Account (including any distributions
therefrom) in violation of this Backstop Subscription Agreement, Issuer shall be entitled to recover from the Backstop Investor and its
affiliates, the associated legal fees and costs in connection with any such action, in the event Issuer or its affiliates, as applicable,
prevails in such action or proceeding. Notwithstanding any else in this Section 10, nothing herein shall be deemed to limit
the Backstop Investor’s right, title, interest or claim to the Trust Account by virtue of the Backstop Investor’s record or
beneficial ownership of any equity interests in Issuer acquired by any means other than pursuant to this Backstop Subscription Agreement.

 

11.               
Miscellaneous.

 

(a)                
Neither this Backstop Subscription Agreement nor any rights that may accrue to the Backstop Investor hereunder (other than the
Backstop Shares acquired hereunder, if any) may be transferred or assigned; provided that the Backstop Investor may assign its

above) except by an instrument in writing, signed by each of the parties hereto. No failure or delay of either party in exercising any
right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise
thereof or the exercise of any other right or power. The rights and remedies of the parties and third-party beneficiaries hereunder are
cumulative and are not exclusive of any rights or remedies that they would otherwise have hereunder.

 

(g)

so executed and delivered shall be construed together and shall constitute one and the same agreement.

not been taken by any Person (including under any Contract binding upon such Sponsor or such Sponsor’s shares of Acquiror Common
Stock or Acquiror Warrants), in each case, to the extent such consent, approval or other action would prevent, enjoin or materially delay
