If to a Company Member, to the address of such Company Member set forth on Exhibit A.

(c) If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy, 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 contemplated transactions 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 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 contemplated transactions be consummated as originally contemplated to the fullest extent possible.

(d) This Agreement, the Merger Agreement and the Ancillary Documents constitute the entire agreement among the parties with respect to the subject matter, and supersede all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter. This Agreement shall not be assigned (whether pursuant to a merger, by operation of law or otherwise) without the prior written consent of the parties, and any attempt to do so without such consent shall be void ab initio.

(e) This Agreement shall be binding upon and inure solely to the benefit of each party, 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.

(g) The parties agree that irreparable damage may occur in the event any provision of this Agreement is not performed in accordance with the terms and that the parties shall be entitled to seek specific performance of the terms, in addition to any other remedy at law or in equity. Each of the parties agrees that it shall not oppose the granting of an injunction, specific performance or other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that the other parties have an adequate remedy at law or that an award of specific performance is not an appropriate remedy for any reason at law or equity. Any party seeking an injunction or injunctions to prevent breaches or threatened breaches of, or to enforce compliance with, this Agreement, when expressly available pursuant to the terms of this Agreement, shall not be required to provide any bond or other security in connection with any such Order.

(h) This Agreement shall be governed by, construed and enforced in accordance with the Laws of the State of Delaware, without regard to its conflict of laws principles. All actions, suits or proceedings (each an “Action”, and, collectively, “Actions”), arising out of or relating to this Agreement shall be heard and determined exclusively in any state or federal court located in Castle County, State of Delaware (or in any appellate court) (the “Specified Courts”). Each party (a) submits to the exclusive jurisdiction of any Specified Court for the purpose of any Action arising out of or relating to this Agreement brought by any party and (b) irrevocably waives, and agrees not to assert by way of motion, defense or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the Contemplated Transactions may not be enforced in or by any Specified Court. Each party agrees that a final judgment in any Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each party irrevocably consents to the service of the summons and complaint and any other process in any other Action relating to the transactions contemplated by this Agreement, on behalf of itself, or its property, by personal delivery of copies of such process to such party at the applicable address set forth in Section 6(b). Nothing in this Section 6(h) shall affect the right of any party to serve legal process in any other manner permitted by Law.

(i) EACH OF THE PARTIES WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY ACTION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE CONTEMPLATED TRANSACTIONS. EACH PARTY (A) CERTIFIES THAT NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SEEK TO ENFORCE THAT FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 6(i).

(j) This Agreement may be executed and delivered (including by electronic 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.

(k) Without further consideration, each party shall use commercially reasonable efforts to 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.

(l) This Agreement shall not be effective or binding upon any Company Member until such time as the Merger Agreement is executed by each of the parties.

(m) If, there are any changes in the Company or the Company securities by way of equity split, dividend, combination or reclassification, or through merger, consolidation, reorganization, recapitalization or business combination, or by any other means, equitable adjustment shall be made to the provisions of this Agreement as may be required so that the rights, privileges, duties and obligations shall continue with respect to the Company Member and its Securities as so changed.

(n) Each Company Member signs this Agreement solely in such Company Member’s capacity as a holder of securities of the Company, and not in any other capacity, and if applicable, this Agreement shall not limit or otherwise affect the actions of any affiliate, employee or designee of such Company Member or any of its affiliates in his or her capacity as an officer or director of the Company.
