Execution Version

(b) If any term or other provision of this Agreement is held to be invalid, illegal or incapable of being enforced by any rule of law, or public policy, in whole or in part, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

(c) This Agreement (together with the BCA, to the extent referred to in this Agreement) constitutes the entire agreement among the parties with respect to the subject matter hereof and supersedes all prior and contemporaneous agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof. This Agreement shall not be assigned (whether pursuant to a merger, by operation of law or otherwise), by any party without the express written consent of the other parties hereto.

(d) This Agreement shall be binding upon and inure solely to the benefit of each party hereto (and their respective successors and permitted assigns), and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

(e) The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement was not performed in accordance with the terms hereof and that the parties shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or in equity.

(f) This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable to contracts executed in and to be performed in that State. Each of the parties hereby irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware or, if (and only if) the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, the Superior Court of the State of Delaware (Complex Commercial Division) or, if (and only if) the Superior Court of the State of Delaware (Complex Commercial Division) declines to accept jurisdiction over a particular matter, any federal court sitting in the State of Delaware, and any appellate courts therefrom (collectively, the “Chosen Courts”). Each of the parties further agrees that notice as provided herein shall constitute sufficient service of process and the parties further waive any argument that such service is insufficient. Each of the parties hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any Action arising out of or relating to this Agreement or the transactions contemplated hereby, (i) any claim that it is not personally subject to the jurisdiction of the Chosen Court as described herein for any reason, (ii) that it or its property is exempt or immune from jurisdiction of any Chosen Court or from any legal process commenced in the Chosen Courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) that (A) the Action in any such court is brought in an inconvenient forum, (B) the venue of such Action is improper or (C) this Agreement, or the subject matter hereof, may not be enforced in or by such court.

Execution Version

(g) Each of the parties hereto hereby waives to the fullest extent permitted by applicable Law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under or in connection with this Agreement and the transaction contemplated hereby. Each of the parties hereto (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce that foregoing waiver and (b) acknowledges that it and the other hereto have been induced to enter into this Agreement and the transaction contemplated hereby, as applicable, by, among other things, the mutual waivers and certifications in this Section 6(g).

(h) This Agreement may be executed and delivered (including executed manually or electronically via DocuSign or other similar services and delivered by facsimile or portable document format (pdf) transmission) in one or more counterparts, and by the different parties in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

(i) Each party hereto shall execute and deliver or cause to be executed and delivered such additional documents and instruments and take all such further action as may be reasonably necessary or desirable to consummate the transactions contemplated by this Agreement.

(j) This Agreement shall not be effective or binding upon any party hereto until after such time as the BCA is executed and delivered by SPAC, the Sellers, the Company, New SPAC and Irish Holdco.

(k) This Agreement may not be amended except by an instrument in writing signed by each of the parties hereto.

(l) Each Sponsor Party shall permit and hereby consents to and authorizes SPAC and the Company to publish and disclose in all documents and schedules filed with the SEC, and any press release or other disclosure document that SPAC or the Company reasonably determines to be necessary in connection with the SPAC Merger or any of the other Transactions, a copy of this Agreement, such Sponsor Parties’ identity and ownership of the Sponsor SPAC Shares held by such Sponsor Party and the nature of such Sponsor Parties’ commitments and obligations under this Agreement.

(m) Each Sponsor Party signs this Agreement solely in such Sponsor Party’s capacity as a shareholder of SPAC. Each Sponsor Party makes no agreement or understanding in this Agreement in such Sponsor Party’s capacity (or in the capacity of any affiliate, partner or employee of such Sponsor Party) as a director or officer of SPAC, Irish Holdco or New SPAC (if such Sponsor Party holds such office). Nothing in this Agreement will limit or affect any actions or omissions taken by any Sponsor Party (or any affiliate, partner or employee of any Sponsor Party) in his, her or its capacity as a director or officer of SPAC, Irish Holdco or New SPAC, and no actions or omissions taken in any Sponsor Party’s capacity (or in the capacity of any affiliate, partner or employee of any Sponsor Party) as a director or officer of SPAC, Irish Holdco or New SPAC Sub shall be deemed a breach of this Agreement. Nothing in this Agreement will be construed to prohibit, limit or restrict any Sponsor Party (or any affiliate, partner or employee of any Sponsor Party) from exercising his or her fiduciary duties as an officer or director of SPAC, Irish Holdco or New SPAC.
