receive a certain number of shares of Parent Common Stock and if applicable and subject to the election of the holders of Company Capital Stock, cash pursuant, and subject to, the terms of the Business Combination Agreement; and 











 WHEREAS, as an inducement to Parent and the Company to enter into the Business Combination
Agreement and to consummate the transactions contemplated therein, the parties hereto desire to agree to certain matters as set forth herein. 

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

ARTICLE I 

STOCKHOLDER SUPPORT AGREEMENT; COVENANTS 

Section 1.1 Binding Effect of Business Combination Agreement. Each Company Stockholder hereby acknowledges that it has had the
opportunity to read the Business Combination Agreement and this Agreement and has had the opportunity to consult with its tax and legal advisors. During the period commencing on the date hereof and ending on the earliest of (a) the First
Effective Time, and (b) such date and time as the Business Combination Agreement shall be terminated in accordance with Section 10.1 thereof (the earlier of (a) and (b), the “Expiration Time”), each Company
Stockholder shall be bound by and comply with Section 6.4 (Acquisition Proposals) of the Business Combination Agreement (and any relevant definitions contained in such Section) as if (a) such Company Stockholder was an original
signatory to the Business Combination Agreement with respect to such provisions, and (b) each reference to the “Company” contained in Section 6.4 (Acquisition Proposals) also referred to such Company Stockholder (but for
the avoidance of doubt, the “Person” referred to in the Acquisition Proposal definition shall refer to the Company, not the Company Stockholder). 

Section 1.2 Publicity. No Company Stockholder may issue any press release or other public communications relating to the
Transactions without the prior approval of Parent and the Company; provided that no Company Stockholder shall be required to obtain consent pursuant to this Section 1.2 to the extent any proposed release or statement is substantially equivalent
to the information that has previously been made public by Parent or the Company. The restriction in this Section 1.2 shall not apply to the extent the public announcement is required by applicable securities Law, any Governmental Authority or
stock exchange rule; provided, however, contract or agree to sell, that in such an event, the Company Stockholder making the announcement shall use its commercially reasonable efforts to consult with Parent and the Company in advance as to
its form, content and timing. 
 Section 1.3 No Transfer. Prior to the Expiration Time, no Company Stockholder shall
(i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, file (or participate in the filing of) a registration statement with
the SEC (other than the Proxy Statement and Registration Statement) or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, with respect to any
Subject Shares; (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Subject Shares (clauses (i) and (i) collectively, a
“Transfer”); (iii) grant any proxies or powers of attorney with respect to any or all of such Company Stockholder’s Subject Shares; (iv) take any action with the intent to prevent, impede, interfere with or adversely
affect such Company Stockholder’s ability to perform its obligations under this Stockholder Support Agreement; or (v) publicly announce any intention to effect any transaction specified in clause (i) or (ii), provided, however, that
(x) if a Company Stockholder is an individual, such Company Stockholder may Transfer any such Subject Shares (A) to any member of such Company Stockholder’s immediate family, or to a trust for the benefit of such Company Stockholder
or any member of such Company Stockholder’s immediate family, the sole trustees of which are such Company Stockholder and/or any member of such Company Stockholder’s immediate family or (B) by


  
 2 












 
will, other testamentary document or under the laws of intestacy upon the death of such Company Stockholder; or (y) if a Company Stockholder is an entity, such Company Stockholder may
Transfer any Subject Shares to any partner, member, or affiliate of such Company Stockholder; provided further, that, in each case, such Transfer shall be permitted only if, as a precondition to such Transfer, the transferee of such Subject Shares
evidences in a writing reasonably satisfactory in form and substance to Parent such transferee’s agreement to be bound by and subject to the terms and provisions hereof to the same extent as such transferring Company Stockholder; provided,
further, that any Transfer permitted under this Section 1.3 shall not relieve a Company Stockholder of its obligations under this Agreement. Any Transfer in violation of this Section 1.3 with respect to a Company Stockholder’s Subject
Shares shall be null and void. 
 Section 1.4 New Shares. In the event that, during the period commencing on the date hereof and
ending at the Expiration Time, (a) any Subject Shares are issued to a Company Stockholder after the date of this Agreement pursuant to any stock dividend, stock split, recapitalization, reclassification, combination or exchange of Subject
Shares or otherwise, (b) a Company Stockholder purchases or otherwise acquires beneficial ownership of any Subject Shares or (c) a Company Stockholder acquires the right to vote or share in the voting of any Subject Shares (collectively,
the “New Securities”), then such New Securities acquired or purchased by such Company Stockholder shall be subject to the terms of this Agreement to the same extent as if they constituted the Subject Shares owned by such Company
Stockholder as of the date hereof. 
 Section 1.5 Stockholder Agreements. Hereafter until the Expiration Time, each
Company Stockholder hereby unconditionally and irrevocably agrees that, at any meeting of the Stockholders of the Company (or any adjournment or postponement thereof), in each case whether held in person or held in virtual format, and in any action
by written consent of the Stockholders of the Company requested by the board of directors of the Company or otherwise undertaken as contemplated by the Transactions (which written consent shall be delivered promptly, and in any event within three
Business Days, after the Registration Statement (as contemplated by the Business Combination Agreement) is declared effective under the Securities Act), such Company Stockholder shall, if a meeting is held, appear at the meeting, in person or by
proxy, or otherwise cause its Subject Shares to be counted as present thereat for purposes of establishing a quorum, and such Company Stockholder shall vote or provide consent (or cause to be voted or consented) covering, in person or by proxy, all
of its Subject Shares: 
 (a) to approve and adopt the Business Combination Agreement and the Transactions, including the Mergers; 

(b) to the extent such Company Stockholder’s Subject Shares include shares of Company Preferred Stock, to authorize and approve the
Company Preferred Stock Conversion; 
 (c) in any other circumstances upon which a consent or other approval is required or sought under
the Company Charter or otherwise sought with respect to the Business Combination Agreement or the Transactions, to vote, consent or approve (or cause to be voted, consented or approved) all of such Company Stockholder’s Subject Shares held at
such time in favor thereof; 
 (d) against and withhold consent with respect to the entry into or consummation of any Acquisition Proposal
(in each case other than the Business Combination Agreement and the Transactions); and 
 (e) against any proposal, action or agreement
that would (i) impede, frustrate, prevent or nullify any provision of this Agreement, the Business Combination Agreement or the Transactions, including the Mergers and the Company Preferred Stock Conversion, (ii) result in a breach in any
respect of any covenant, representation, warranty or any other obligation or agreement of the Company under the Business Combination Agreement or (iii) result in any of the conditions set forth in Article 9 of the Business Combination Agreement
not being fulfilled; 

  
 3 












 provided, however, that such Company Stockholder shall not vote or provide consent with
respect to any of its Subject Shares that are not held by the Company’s directors, officers, affiliates or greater than 5% shareholders of the Company, or take any other action, in each case to the extent any such vote, consent or other action
would preclude Parent from filing the Registration Statement with the SEC as contemplated by the Business Combination Agreement. Each Company Stockholder hereby agrees that it shall not commit or agree to take any action inconsistent with the
foregoing prior to the Expiration Time. 
 Section 1.6 No Challenges. Each Company Stockholder agrees not to commence, join in,
facilitate, assist or encourage, and agrees to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Parent, First Merger Sub, Second Merger Sub, the Company or any of
their respective successors, directors or officers (a) challenging the validity of, or seeking to enjoin the operation of, any provision of this Agreement or (b) alleging a breach of any fiduciary duty of any person in connection with the
evaluation, negotiation or entry into the Business Combination Agreement. 
 Section 1.7 Affiliate Agreements. Each Company
Stockholder hereby agrees and consents to the termination of the Contracts set forth on Schedule II to which such Company Stockholder is party, effective as of the First Effective Time without any further liability or obligation to the
Company, any of the Company’s Subsidiaries, Parent, First Merger Sub or Second Merger Sub. 
 Section 1.8 Amended Registration
Rights Agreement; Lock-Up Agreement. Each of the Company Stockholders set forth on Schedule III will deliver, substantially simultaneously with the First Effective Time, (a) a duly executed
copy of the Amended Registration Rights Agreement substantially in the form attached as Exhibit F to the Business Combination Agreement and (b) a duly-executed copy of the Lock-Up Agreement substantially
in the form attached as Exhibit G to the Business Combination Agreement. 
 Section 1.9 Further Assurances. Each Company
Stockholder shall execute and deliver, or cause to be delivered, such additional documents, and take, or cause to be taken, all such further actions and do, or cause to be done, all things reasonably necessary (including under applicable Laws), or
reasonably requested by Parent or the Company, to effect the actions and consummate the Mergers and the other transactions contemplated by this Agreement and the Business Combination Agreement (including the Transactions), in each case, on the terms
and subject to the conditions set forth therein and herein, as applicable. 
 Section 1.10 No Inconsistent Agreement; No Voting
Trusts or other Arrangements. Each Company Stockholder hereby represents and covenants that such Company Stockholder has not entered into, and shall not enter into, any agreement, or amend or modify any existing agreement that would restrict,
limit or interfere with the performance of such Company Stockholder’s obligations hereunder. Company Stockholder agrees that prior to the Expiration Time, Company Stockholder will not, and will not permit any entity under Company
Stockholder’s control to, deposit any of the Subject Shares in a voting trust, grant any proxies with respect to the Subject Shares, or subject any of the Subject Shares to any arrangement with respect to the voting of the
Subject Shares other than as provided hereunder and under the Contracts set forth on Schedule II. 

  
 4 












 Section 1.11 Consent to Disclosure. Each Company Stockholder hereby consents to
the publication and disclosure in the Proxy Statement and Registration Statement (and, as and to the extent otherwise required by applicable securities Laws or the SEC or any other securities authorities, any other documents or communications
provided by Parent or the Company to any Governmental Authority or to securityholders of Parent) of such Company Stockholder’s identity and beneficial ownership of Subject Shares and the nature of such Company Stockholder’s commitments,
arrangements and understandings under and relating to this Agreement and, if deemed appropriate by Parent or the Company, a copy of this Agreement. Each Company Stockholder will promptly provide any information reasonably requested by Parent or the
Company for any regulatory application or filing made or approval sought in connection with the Transactions (including filings with the SEC). 

ARTICLE II 

REPRESENTATIONS AND WARRANTIES 

Section 2.1 Representations and Warranties of the Company Stockholders. Each Company Stockholder represents and warrants as of the
date hereof to Parent and the Company (solely with respect to itself, himself or herself and not with respect to any other Company Stockholder) as follows: 

(a) Organization; Due Authorization. If such Company Stockholder is not an individual, it is duly organized, validly existing and in
good standing under the Laws of the jurisdiction in which it is incorporated, formed, organized or constituted, and the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby are within
such Company Stockholder’s corporate, limited liability company or organizational powers and have been duly authorized by all necessary corporate, limited liability company or organizational actions on the part of such Company Stockholder. If
such Company Stockholder is an individual, such Company Stockholder has full legal capacity, right and authority to execute and deliver this Agreement and to perform his or her obligations hereunder. This Agreement has been duly executed and
delivered by such Company Stockholder and, assuming due authorization, execution and delivery by the other parties to this Agreement, this Agreement constitutes a legally valid and binding obligation of such Company Stockholder, enforceable against
such Company Stockholder in accordance with the terms hereof (subject to the Enforceability Exceptions). If this Agreement is being executed in a representative or fiduciary capacity, the Person signing this Agreement has full power and authority to
enter into this Agreement on behalf of the applicable Company Stockholder. 
 (b) Ownership. Such Company Stockholder is the record
and beneficial owner (as defined in the Securities Act) of, and has good title to, all of such Company Stockholder’s Subject Shares, and there exist no Liens or any other limitation or restriction (including any restriction on the right to
vote, sell or otherwise dispose of such Subject Shares) affecting any such Subject Shares, other than Liens or other limitations and restrictions pursuant to (i) this Agreement, (ii) the Company Charter, (iii) the Business Combination
Agreement, (iv) any Contract set forth on Schedule II or (v) any applicable securities Laws, including transfer restrictions under the Securities Act. Such Company Stockholder’s Subject Shares are the only shares of capital
stock in the Company owned of record or beneficially by such Company Stockholder on the date of this Agreement, and none of such Company Stockholder’s Subject Shares are subject to any proxy, voting trust or other agreement or arrangement with
respect to the voting of such Subject Shares, except as provided hereunder and under the Contracts set forth on Schedule II. Such Company Stockholder does not hold or own any rights to acquire (directly or indirectly) any equity securities of
the Company or any equity securities convertible into, or which can be exchanged for, equity securities of the Company, other than any Company Warrants or Company Options held by such Company Stockholder. 

(c) No Conflicts. The execution and delivery of this Agreement by such Company Stockholder does not, and the performance by such
Company Stockholder of his, her or its obligations hereunder will not, (i) if such Company Stockholder is not an individual, conflict with or result in a violation of the organizational documents of such Company Stockholder or (ii) require
any consent or 

  
 5 












 
approval that has not been given or other action that has not been taken by any Person (including under any Contract binding upon such Company Stockholder or such Company Stockholder’s
Subject Shares) to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by such Company Stockholder of its, his or her obligations under this Agreement. 

(d) Litigation. There are no Actions pending against such Company Stockholder, or to the knowledge of such Company Stockholder
threatened against such Company Stockholder, before (or, in the case of threatened Actions, that would be before) any arbitrator or any Governmental Authority, which in any manner challenges or seeks to prevent, enjoin or materially delay the
performance by such Company Stockholder of its, his or her obligations under this Agreement. 
 (e) Adequate Information. Such
Company Stockholder is a sophisticated stockholder and has adequate information concerning the business and financial condition of Parent and the Company to make an informed decision regarding this Agreement and the Transactions and has
independently and without reliance upon Parent or the Company and based on such information as such Company Stockholder has deemed appropriate, made its own analysis and decision to enter into this Agreement. Such Company Stockholder acknowledges
that Parent and the Company have not made and do not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement. Such Company Stockholder acknowledges that the agreements
contained herein with respect to the Subject Shares held by such Company Stockholder are irrevocable. 
 (f) Brokerage Fees. No
broker, finder, investment banker or other Person is entitled to any brokerage fee, finders’ fee or other commission in connection with the Transactions based upon arrangements made by such Company Stockholder, for which the Company or any of
its Subsidiaries may become liable. 
 (g) Acknowledgment. Such Company Stockholder understands and acknowledges that each of Parent
and the Company is entering into the Business Combination Agreement in reliance upon such Company Stockholder’s execution and delivery of this Agreement. 

ARTICLE III 

MISCELLANEOUS 

Section 3.1 Termination. This Agreement and all of its provisions shall terminate and be of no further force or effect upon the
earlier of (a) the Expiration Time and (b) as to each Company Stockholder, the written agreement of Parent, the Company and such Company Stockholder. Upon such termination of this Agreement, all obligations of the parties under this
Agreement will terminate, without any liability or other obligation on the part of any party hereto to any Person in respect hereof or the transactions contemplated hereby, and no party hereto shall have any claim against another (and no person
shall have any rights against such party), whether under contract, tort or otherwise, with respect to the subject matter hereof; provided, however, that the termination of this Agreement shall not relieve any party hereto from
liability arising in respect of any breach of this Agreement prior to such termination. This ARTICLE III shall survive the termination of this Agreement. 

Section 3.2 Governing Law. This Agreement, and all claims or causes of action based upon, arising out of, or related to this
Agreement or the Transactions, shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without giving effect to principles or rules of conflict of Laws to the extent such principles or rules would require or permit
the application of Laws of another jurisdiction. Any proceeding or Action based upon, arising out of or related to this Agreement or the Transactions must be brought in the Court of Chancery of the State of Delaware (or, to the extent such Court
does not have subject matter jurisdiction, the Superior Court of the State of Delaware), or, if it has or 

  
 6 












 
can acquire jurisdiction, in the United States District Court for the District of Delaware, and each of the parties irrevocably submits to the exclusive jurisdiction of each such court in any
such proceeding or Action, waives any objection it may now or hereafter have to personal jurisdiction, venue or to convenience of forum, agrees that all claims in respect of the proceeding or Action shall be heard and determined only in any such
court, and agrees not to bring any proceeding or Action arising out of or relating to this Agreement or the Transactions in any other court. Nothing herein contained shall be deemed to affect the right of any party to serve process in any manner
permitted by Law or to commence Legal Proceedings or otherwise proceed against any other party in any other jurisdiction, in each case, to enforce judgments obtained in any Action, suit or proceeding brought pursuant to this Section 3.2. 

Section 3.3 Waiver Of Jury Trial. Each party acknowledges and agrees that any controversy which may arise under this Agreement and
the Transactions is likely to involve complicated and difficult issues, and therefore each such party hereby irrevocably, unconditionally and voluntarily waives any right such party may have to a trial by jury in respect of any Action, suit or
proceeding directly or indirectly arising out of or relating to this Agreement or any of the Transactions. 
 Section 3.4
Assignment. No party hereto shall assign this Agreement or any part hereof without the prior written consent of the other parties hereto and any such transfer without prior written consent shall be void. Subject to the foregoing, this
Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns. 

Section 3.5 Specific Performance. The parties hereto agree that irreparable damage may occur in the event that any of the
provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties hereto shall be entitled to an injunction or injunctions to prevent breaches of this
Agreement and to specific enforcement of the terms and provisions of this Agreement, in addition to any other remedy to which any party is entitled at law or in equity. In the event that any Action shall be brought in equity to enforce the
provisions of this Agreement, no party shall allege, and each party hereby waives the defense, that there is an adequate remedy at law, and each party agrees to waive any requirement for the securing or posting of any bond in connection therewith.

 Section 3.6 Amendment; Waiver. This Agreement may not be amended, changed, supplemented, waived or otherwise modified or
terminated, except upon the execution and delivery of a written agreement executed by Parent, the Company and the Company Stockholder. 

Section 3.7 Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent
jurisdiction, the other provisions of this Agreement shall remain in full force and effect. The parties further agree that if any provision contained herein is, to any extent, held invalid or unenforceable in any respect under the Laws governing
this Agreement, they shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by Law and, to the extent necessary, shall amend or otherwise modify this Agreement to
replace any provision contained herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the parties.
