actions required to be taken pursuant to Section 1.4 and Section 1.5 of this Sponsor Agreement.

REPRESENTATIONS AND WARRANTIES 

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

(a) Organization; Due Authorization. If such Sponsor Party 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 Sponsor Agreement and the consummation of the transactions contemplated hereby are within
such Sponsor Party’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 Sponsor Party. If such Sponsor
Party is an 

  
 4 













 
individual, such Sponsor Party has full legal capacity, right and authority to execute and deliver this Sponsor Agreement and to perform his or her obligations hereunder. This Sponsor Agreement
has been duly executed and delivered by such Sponsor Party and, assuming due authorization, execution and delivery by the other parties to this Sponsor Agreement, this Sponsor Agreement constitutes a legally valid and binding obligation of such
Sponsor Party, enforceable against such Sponsor Party in accordance with the terms hereof (except as enforceability may be limited by bankruptcy Laws, other similar Laws affecting creditors’ rights and general principles of equity affecting the
availability of specific performance and other equitable remedies). If this Sponsor Agreement is being executed in a representative or fiduciary capacity, the Person signing this Sponsor Agreement has full power and authority to enter into this
Sponsor Agreement on behalf of the applicable Sponsor Party. 
 (b) Ownership. The Sponsor is the record and beneficial owner of, and
has good title to, all of the Sponsor’s Subject Securities listed across from the Sponsor’s name on Schedule I hereto and each other Sponsor Party holds interest in the Sponsor representing the economic benefit in the Subject
Securities listed across from such Sponsor Party’s name on Schedule I hereto, 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
Securities (other than transfer restrictions under the Securities Act)) affecting any such Subject Securities owned by the Sponsor, other than Liens pursuant to (i) this Sponsor Agreement, (ii) the Acquiror Governing Documents,
(iii) the Merger Agreement, (iv) the Insider Letter or (v) any applicable securities Laws. The Sponsor’s Subject Securities are the only equity securities in Acquiror owned of record or beneficially by the Sponsor on the date of
this Sponsor Agreement, and none of the Sponsor’s Subject Securities are subject to any proxy, voting trust or other agreement or arrangement with respect to the voting of such Subject Securities, except as provided hereunder and under the
Insider Letter. Other than the Acquiror Warrants held by such Sponsor Party and the Subscription Agreement to which the Sponsor is a party, such Sponsor Party does not hold or own any rights to acquire (directly or indirectly) any equity securities
of Acquiror or any equity securities convertible into, or which can be exchanged for, equity securities of Acquiror. 
 (c) No
Conflicts. The execution and delivery of this Sponsor Agreement by such Sponsor Party does not, and the performance by such Sponsor Party of his, her or its obligations hereunder will not, (i) if such Sponsor Party is not an individual,
conflict with or result in a violation of the organizational documents of such Sponsor Party or (ii) require any consent or approval that has not been given or other action that has not been taken by any Person (including under any Contract
binding upon such Sponsor Party or such Sponsor Party’s Subject Securities), in each case, to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by such Sponsor Party of its, his or her
obligations under this Sponsor Agreement. 
 (d) Litigation. There are no Actions pending against such Sponsor Party, or to the
knowledge of such Sponsor Party threatened against such Sponsor Party, 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 Sponsor Party of its, his or her obligations under this Sponsor Agreement.

Disclosure Letter, no broker, finder, investment banker or other Person is entitled to any brokerage fee, finders’ fee or other commission in connection with the transactions contemplated by the Merger Agreement based upon arrangements made by
such Sponsor Party, for which Acquiror or any of its Subsidiaries may become liable. 
 (f) Affiliate Arrangements. Except as set
forth on Schedule II attached hereto or any Acquiror SEC Filings, neither such Sponsor Party nor any anyone related by blood, marriage or adoption to such Sponsor Party or, to the knowledge of such Sponsor Party, any Person in which such
Sponsor Party has a direct or indirect legal, contractual or beneficial ownership of 5% or greater is party to, or has any rights with respect to or arising from, any Contract with Acquiror or its Subsidiaries. 

(g) Acknowledgment. Such Sponsor Party understands and acknowledges that each of Acquiror and the Company is entering into the Merger
Agreement in reliance upon such Sponsor Party’s execution and delivery of this Sponsor Agreement.

such termination of this Sponsor Agreement, all obligations of the parties under this Sponsor 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,
