pursuant to which such other investors have agreed to subscribe for and purchase, and the Issuer has agreed to issue and sell to such other investors (the “Other Subscribers”), on the Closing Date, Class A Shares at the Share
Purchase Price (the “Other Subscription Agreements”). 
 NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties and covenants, and subject to the conditions, herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

Issuer’s share register and will provide to the Subscriber evidence of such issuance from the Issuer’s transfer agent. In the event the Closing does not occur within three (3) business days of the Scheduled Closing Date, the Issuer
shall promptly (but not later than two (2) business days thereafter) return the Purchase Price to Subscriber, and any book-entries for the Shares shall be deemed cancelled; provided that, unless this Agreement has been terminated

alleges that the 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, individually or in the aggregate, be

schedule, prospectus, proxy, registration statement and other document, if any, filed by the Issuer with the Commission since its initial registration of the Class A Shares (the “SEC Documents”), which SEC Documents, as of
their respective filing dates, complied in all material respects with the requirements of the Exchange Act or the Securities Act applicable to the SEC Documents and the rules and regulations of the Commission promulgated thereunder applicable to the
SEC Documents. None of the SEC Documents filed under the Exchange Act or the Securities Act (except to the extent that information contained in any SEC Document has been superseded by a later timely filed SEC Document) contained, when filed any
untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The Issuer has timely filed

entity or arbitrator outstanding against the Issuer.

Securities, Inc., in their capacities as placement agents for the offer and sale of the Acquired Shares (in such capacities, the “Placement Agents”), the Issuer has not paid, and is not obligated to pay, any brokerage, finder’s
or other commission or similar fee in connection with its issuance and sale of the Acquired Shares, including, for the avoidance of doubt, any fee or commission payable to any stockholder or affiliate, as defined in Rule 144 under the Securities Act
(“Affiliate”), of the Issuer.

 5. Registration Rights. 

a. The Issuer agrees that, within thirty (30) calendar days after the consummation of the Transactions (the “Filing
Date”), the Issuer will file with the Commission (at the Issuer’s sole cost and expense) a registration statement registering the resale of the Acquired Shares (the “Registration Statement”), and the 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 90th calendar day (or 120th calendar day if the Commission
notifies the Issuer that it will “review” the Registration Statement) following the Closing and (ii) the 10th business day after the date the Issuer is notified (orally or in writing, whichever is earlier) by the Commission that the
Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Date”); provided, however, that the Issuer’s obligations to include the
Acquired Shares in the Registration Statement are contingent upon Subscriber furnishing in writing to the Issuer such information regarding Subscriber, the securities of the Issuer held by Subscriber and the intended method of disposition of the
Acquired Shares as shall be reasonably requested by the Issuer to effect the registration of the Acquired Shares, and Subscriber shall execute such documents in connection with such registration as the Issuer may reasonably request that are
customary of a selling stockholder in similar situations, including providing that the Issuer shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period or as
permitted hereunder; provided that Subscriber shall not in connection with the foregoing be required to execute any lock up or similar agreement providing contractual restrictions on the Subscriber’s ability to transfer the Acquired Shares.
The Issuer will provide a draft of the Registration Statement to the Subscriber for review at least two (2) business days in advance of filing the Registration Statement. Unless otherwise agreed to in writing by the Subscriber, the
Subscriber shall not be identified as a statutory underwriter in the Registration Statement unless requested by the Commission or another regulatory agency; provided, that if the Commission or another regulatory agency requests that a Subscriber be
identified as a statutory underwriter in the Registration Statement, Subscriber will have the opportunity to withdraw from the Registration Statement upon its prompt written request to the Issuer. Notwithstanding the foregoing, if the Commission
prevents the Issuer from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Acquired Shares by the applicable
stockholders or otherwise, such Registration Statement shall register for resale such number of Acquired Shares which is equal to the maximum number of Acquired Shares as is permitted by the Commission. In such event, the number of Acquired Shares
to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders. For purposes of clarification, any failure by the Issuer to file the Registration Statement by the
Filing Date or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve the Issuer of its obligations to file or effect the Registration Statement as set forth above in this Section 5.

 b. In the case of the registration, qualification, exemption or compliance effected by the Issuer pursuant to this Subscription Agreement,
the Issuer shall, upon reasonable request, inform Subscriber as to the status of such registration, qualification, exemption and compliance. At its expense the Issuer shall: 

(i) except for such times as the 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 the Issuer determines to obtain, continuously effective with respect to Subscriber, 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: (i) Subscriber ceases to hold any Acquired Shares or (ii) the date all
Acquired Shares held by Subscriber 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 the
Issuer to be in compliance with the current public information required under Rule 144(c)(1) or Rule 144(i)(2), as applicable, and (iii) two (2) years from the effective date of the Registration Statement. 

  
 10 













 (ii) advise Subscriber, as expeditiously as possible: 

(1) when a Registration Statement or any amendment thereto has been filed with the Commission and when such Registration Statement or any
post-effective amendment thereto has become effective; 
 (2) after it shall receive notice or obtain knowledge thereof, of the issuance by
the Commission 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 the Issuer of any notification with respect to the suspension of the qualification of the Acquired 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 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. 

(iii) 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) upon the occurrence of any event contemplated above, except for such times as the Issuer is
permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the 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 Acquired 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) without limitation to section 3(j) above, use its commercially reasonable efforts to cause all Acquired Shares to be listed on each
securities exchange or market, if any, on which the Class A Shares issued by the Issuer have been listed; 
 (vi) use its commercially
reasonable efforts (i) to take all other steps necessary to effect the registration of the Acquired Shares contemplated hereby and (ii) to file all reports and other materials required to be filed by the Exchange Act so long as the Issuer
remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144 to enable Subscriber to sell the Acquired Shares under Rule 144 for so long as the Subscriber holds
Acquired Shares; and 
 (vii) cause the removal of all restrictive legends from all Acquired Shares, including but not limited to the legend
set forth above in Section 2(b), at Subscriber’s request, when the Acquired Shares are sold pursuant to Rule 144 under the Securities Act or the Registration Statement or may be sold without restriction under Rule 144. In connection
therewith, if required by the Issuer’s transfer agent, the Issuer will promptly cause an opinion of counsel to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required
by the transfer agent that authorize and direct the transfer agent to issue such Acquired Shares without any such legend. 

  
 11 













 c. Notwithstanding anything to the contrary in this Subscription Agreement, the Issuer shall
be entitled to delay or postpone the effectiveness of the Registration Statement, and from time to time to require Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, if the Issuer determines that in
order for the Registration Statement to not contain a material misstatement or omission, 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, or if such filing or use could materially affect a bona fide business or financing transaction of the Issuer or its subsidiaries or would require additional disclosure by the Issuer in the Registration Statement of material
information that the Issuer has a bona fide business purpose for keeping confidential (each such circumstance, a “Suspension Event”); provided, however, that (i) the Issuer may not delay or suspend the
Registration Statement on more than two occasions or for more than sixty (60) consecutive calendar days, or more than one hundred and twenty (120) total calendar days, in each case during any twelve-month period and (ii) the Issuer
shall use commercially reasonable efforts to make the Registration Statement available for sale by the Subscriber of its Acquired Shares as soon as practicable thereafter. Upon receipt of any written notice from the 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, Subscriber agrees that it will immediately discontinue offers
and sales of the Acquired Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until Subscriber receives copies of a supplemental or amended prospectus (which the 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 the Issuer that it may resume such offers and sales;
provided, for the avoidance of doubt, that the Issuer shall not include any material non-public information in any such written notice. If so directed by the Issuer, Subscriber will deliver to the
Issuer or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Acquired Shares in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the
prospectus covering the Acquired Shares shall not apply (i) to the extent Subscriber is required to retain a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or
(b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on archival servers as a result of automatic data
back-up. 
 d. Subscriber may deliver written notice (an
“Opt-Out Notice”) to the Issuer requesting that Subscriber not receive notices from the Issuer otherwise required by this Section 5; provided, however,
that Subscriber may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from Subscriber (unless subsequently revoked), (i) the Issuer
shall not deliver any such notices to Subscriber and Subscriber shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to Subscriber’s intended use of an effective Registration Statement,
Subscriber will notify the Issuer in writing at least two (2) business days in advance of such intended use, and if a notice of a Suspension Event was previously delivered (or would have been delivered but for the provisions of this
Section 5(d)) and the related suspension period remains in effect, the Issuer will so notify Subscriber, within one (1) business day of Subscriber’s notification to the Issuer, by delivering to Subscriber a copy
of such previous notice of Suspension Event, and thereafter will provide Subscriber with the related notice of the conclusion of such Suspension Event immediately upon its availability. 

e. For purposes of this Section 5, “Acquired Shares” shall mean, as of any date of determination,
the Acquired Shares purchased by Subscriber pursuant to this Subscription Agreement and any other equity security issued or issuable with respect to such Acquired Shares by way of share split, dividend, distribution, recapitalization, merger,
exchange, replacement or similar event, and “Subscriber” shall include any person to whom the rights under this Section 5 shall have been duly assigned. 

  
 12 













 f. Issuer shall indemnify Subscriber (to the extent a seller under the Registration
Statement), its officers, directors, partners, members, managers, employees, stockholders, advisers and agents, and each person who controls Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including without limitation reasonable attorneys’ fees) and expenses (collectively, “Losses”),
as incurred, that arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement (or incorporated by reference therein), any prospectus included in the Registration Statement or any
form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the
statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except to the extent that such untrue statements or alleged untrue statements or
omissions or alleged omissions, are based upon information regarding Subscriber furnished in writing to Issuer by Subscriber expressly for use therein. 

g. Subscriber shall, severally and not jointly with any Other Subscriber, indemnify and hold harmless the Issuer, its directors, officers,
agents and employees, and each person who controls the Issuer (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), to the fullest extent permitted by applicable law, from and against all Losses, as
incurred, that arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or
supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus,
or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statements or alleged untrue statements, or omissions, or alleged
omissions, are based upon information regarding Subscriber furnished in writing to the Issuer by Subscriber expressly for use therein provided, however, that the indemnification contained in this Section 5(g) shall not
apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of Subscriber (which consent shall not be unreasonably withheld, conditioned or delayed). In no event shall the liability of Subscriber exceed the
net proceeds received by Subscriber upon the sale of the Acquired Shares giving rise to such indemnification obligation. Subscriber shall notify the Issuer promptly of the institution, threat or assertion of any proceeding arising from or in
connection with the transactions contemplated by this Section 5 of which Subscriber is aware. 
 h. If the
indemnification provided under this Section 5 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to
herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as
is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by
reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such
indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a
result of the losses or other liabilities referred to above shall be subject to the limitations set forth in this Section 5 and deemed to include 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 5 from any 

  
 13 













 
person who was not guilty of such fraudulent misrepresentation. Each indemnifying party’s obligation to make a contribution pursuant to this Section 5(h) shall be
individual, not joint and several, and in no event shall the liability of Subscriber hereunder exceed the net proceeds received by Subscriber upon the sale of the Acquired Shares giving rise to such indemnification obligation. 

6. Termination. This 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 earlier to occur of (a) such date and time as the Merger Agreement is terminated in accordance with the
terms therein, (b) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, (c) if any of the conditions to Closing set forth in Section 2(c) are not satisfied on
or prior to the Closing Date and, as a result thereof, the transactions contemplated by this Subscription Agreement, including, for the avoidance of doubt, the Transactions, are not consummated at the Closing or (d) on or after March 21,
2021 if the Closing has not occurred on or prior to such date (the “Outside Date”); provided, however, that (x) if the Issuer’s stockholders approve the Required Extension (as defined in the Merger
Agreement), the Outside Date will be automatically extend to the earlier of (i) such extension date and (ii) July 13, 2021, provided, further, 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 reasonable and documented out-of-pocket losses,
liabilities or damages arising from such breach. The Issuer shall promptly notify Subscriber of the termination of the Merger Agreement promptly after the termination of such agreement. 

7. Trust Account Waiver. Subscriber acknowledges that the Issuer is a blank check company with the powers and privileges to effect a
merger, asset acquisition, reorganization or similar business combination involving the Issuer and one or more businesses or assets. Subscriber further acknowledges that, as described in the Issuer’s prospectus relating to its initial public
offering dated March 7, 2019 (the “Prospectus”), available at www.sec.gov, substantially all of the Issuer’s assets consist of the cash proceeds of the Issuer’s initial public offering and private placements of its
securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of the Issuer, its public stockholders and the underwriters of the Issuer’s initial public
offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to the 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
Prospectus. For and in consideration of the Issuer entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, Subscriber, on behalf of itself and its representatives, hereby irrevocable waives any and
all right, title and interest, or any claim of any kind they have or may have in the future arising out of this Subscription Agreement, in or to any monies held in the Trust Account, and agrees not to seek recourse against the Trust Account as a
result of, or arising out of, this Subscription Agreement; provided, however, that nothing in this Section 7 shall be deemed to limit any Subscriber’s right, title, interest or claim to the Trust Account by
virtue of such Subscriber’s record or beneficial ownership of securities of the Issuer acquired by any means other than pursuant to this Subscription Agreement, including but not limited to any redemption right with respect to any such
securities of the Issuer. 
 8. Exculpation of Placement Agents. Subscriber acknowledges and agrees for the express benefit of
the Placement Agents and their Affiliates and their and their Affiliates’ respective officers, directors, employees or representatives that neither the Placement Agents nor any of their Affiliates or any of their or their Affiliates’
officers, directors, employees or representatives shall, absent gross negligence, fraud or willful misconduct, be liable to any Subscriber, pursuant to this Subscription Agreement or any other subscription agreement related to the private placement
of the Acquired Shares, the negotiation hereof or thereof or the subject matter hereof or thereof, or the transactions contemplated hereby or thereby, for any action heretofore or hereafter taken or omitted to be taken by any of them in connection
with the purchase of the Acquired Shares by such Subscriber. 

  
 14 













 9. Miscellaneous.

Subscription Agreement, makes the representations and warranties in Section 4 and completes Schedule A hereto. In the event of such a transfer or assignment, Subscriber shall update Schedule B to provide the
information required therein. 
 d. All the agreements, representations and warranties made by each party hereto in this Subscription
Agreement shall survive the Closing. 
 e. The Issuer may request from Subscriber such additional information as the Issuer may reasonably
deem necessary to evaluate the eligibility of Subscriber to acquire the Acquired Shares, and Subscriber shall promptly provide such information as may be reasonably requested, to the extent readily available and to the extent consistent with its
internal policies and procedures; provided, that the Issuer agrees to keep any such information provided by Subscriber confidential. 

f. This Subscription Agreement may not be modified, waived or terminated except by an instrument in writing, signed by the party against whom
enforcement of such modification, waiver, or termination is sought. 
 g. This Subscription Agreement constitutes the entire agreement, and
supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof. 

h. Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto and
their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon,
such heirs, executors, administrators, successors, legal representatives and permitted assigns. 
 i. If any provision of this Subscription
Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and
effect. The parties hereto shall execute and deliver all such further instruments and documents and take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the

 SCHEDULE A 

ELIGIBILITY REPRESENTATIONS OF SUBSCRIBER 

This Schedule must be completed by Subscriber and forms a part of the Subscription Agreement to which it is attached. Capitalized terms used and not
otherwise defined in this Schedule have the meanings given to them in the Subscription Agreement. Subscriber must check the applicable box in either Part A or Part B below and the applicable box in Part C below. 

 

	A.	 QUALIFIED INSTITUTIONAL BUYER STATUS 



(Please check the applicable subparagraphs): 
  

	☐	 Subscriber is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act (a
