If Sponsor 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 Sponsor’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 Sponsor. If Sponsor is an individual, Sponsor 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 Sponsor 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 Sponsor, enforceable against Sponsor 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.

(b) Ownership. Sponsor is the record and beneficial owner (as defined in the Securities Act) of, and has good title to, all of Sponsor’s Subject Securities listed across from Sponsor’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, 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. Sponsor’s Subject Securities are the only equity securities in Acquiror owned of record or beneficially by Sponsor on the date of this Sponsor Agreement, and none of 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 Sponsor, Sponsor 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 Sponsor does not, and the performance by Sponsor of his, her or its obligations hereunder will not, (i) if Sponsor is not an individual, conflict with or result in a violation of the organizational documents of Sponsor 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 Sponsor or Sponsor’s Subject Securities), in each case, to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by Sponsor of its, his or her obligations under this Sponsor Agreement.

(d) Litigation. There are no Actions pending against Sponsor, or to the knowledge of Sponsor threatened against Sponsor, 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 Sponsor of its, his or her obligations under this Sponsor Agreement.

(e) Brokerage Fees. Except as described on Section 5.13 of the Acquiror 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 Sponsor, for which Acquiror or any of its Affiliates may become liable.

(f) Affiliate Arrangements. Except as set forth on Schedule II attached hereto, neither Sponsor nor any anyone related by blood, marriage or adoption to Sponsor or, to the knowledge of Sponsor, any Person in which Sponsor 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. Sponsor understands and acknowledges that each of Acquiror and the Company is entering into the Merger Agreement in reliance upon Sponsor’s execution and delivery of this Sponsor Agreement.
