REPRESENTATIONS AND WARRANTIES

Section 2.1     Representations and Warranties of the Sponsors. Each Sponsor 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) as follows:

(a)            Organization; Due Authorization. If such 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 such 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 such Sponsor. If such Sponsor is an individual, such 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 such 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 such Sponsor, enforceable against such 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. Such Sponsor is the record and beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act) of, and has good title to, all of such Sponsor’s Acquiror Ordinary Shares and Acquiror Warrants, 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 Acquiror Ordinary Shares or Acquiror Warrants (other than transfer restrictions under the Securities Act)) affecting any such Acquiror Ordinary Shares or Acquiror Warrants, other than Liens pursuant to (i) this Sponsor Agreement, (ii) the Acquiror Governing Documents, (iii) the Merger Agreement, (iv) the Sponsor Letter Agreement or (v) any applicable securities Laws. Such Sponsor’s Acquiror Ordinary Shares and Acquiror Warrants are the only equity securities in Acquiror owned of record or beneficially by such Sponsor on the date of this Sponsor Agreement, and none of such Sponsor’s Acquiror Ordinary Shares or Acquiror Warrants are subject to any proxy, voting trust or other agreement or arrangement with respect to the voting of such Acquiror Ordinary Shares or Acquiror Warrants, except as provided hereunder and under the Sponsor Letter Agreement. Other than the Acquiror Warrants, such 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 such Sponsor does not, and the performance by such Sponsor of his, her or its obligations hereunder will not, (i) if such Sponsor is not an individual, conflict with or result in a violation of the organizational documents of such 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 such Sponsor or such Sponsor’s Acquiror Ordinary Shares or Acquiror Warrants), in each case, to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by such Sponsor of its, his or her obligations under this Sponsor Agreement.

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

(e)            Brokerage Fees. Except as described on Section 5.15 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 such 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 such Sponsor nor any anyone related by blood, marriage or adoption to such Sponsor or, to the knowledge of such Sponsor, any Person in which such 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. Such Sponsor understands and acknowledges that each of Acquiror and the Company is entering into the Merger Agreement in reliance upon such Sponsor’s execution and delivery of this Sponsor Agreement.

(h)            No Other Representations or Warranties. Except for the representations and warranties made by the Sponsors in this Article II, no Sponsor nor any other Person makes any express or implied representation or warranty to Acquiror or the Company in connection with this Agreement or the transactions contemplated by this Agreement, and each Sponsor expressly disclaims any such other representations or warranties.
