For greater certainty, nothing shall limit any director of the Company from fulfilling his or her fiduciary duties as a director of the Company or from engaging in such capacity in any discussions or negotiations permitted under the Transaction Agreement.

SECTION 7.          General Provisions.

All references in this Agreement to any “Section” are to the corresponding Section of this Agreement unless otherwise specified;

(d)          Severability. If any term or other provision of this Agreement is determined by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other terms, provisions and conditions of this Agreement shall nevertheless remain in full force and effect.

(i)    This Agreement and any other document or instrument delivered pursuant hereto, and all claims or causes of action (whether in contract or tort) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution, termination, performance or nonperformance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement), shall be governed by the internal laws of the State of New York, without regard to its conflicts of law principles.

(ii)    Each of the parties hereto irrevocably agrees that any and all actions and proceedings with respect to this Agreement and the rights and obligations arising out of or relating to this Agreement, shall be brought and determined exclusively in the United States District Court for the Southern District of New York; provided, however, that, if subject matter jurisdiction is unavailable in that court, then all such claims shall be transferred to or otherwise brought, heard and determined exclusively in the Supreme Court of the State of New York, County of New York (as applicable, the “Agreed Court”).

Each of the parties hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the Agreed Court for any reason, (b) any claim that it or its property is exempt or immune from jurisdiction of such court or from any legal process commenced in such court (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) to the fullest extent permitted by applicable Law, any claim that (i) the action or proceedings in such court is brought in an inconvenient forum, (ii) the venue of such action or proceeding is improper or (iii) this Agreement, or the subject matter of this Agreement, may not be enforced in or by the Agreed Court.

(iii)    EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHTS TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

(h)          Binding Effect; Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, directly or indirectly, by operation of Law or otherwise, by any of the parties without the prior written consent of the other parties, except that (i) Parent may assign, in its sole discretion, any of or all of its rights, interests and obligations under this Agreement to any wholly owned subsidiary of Parent, but no such assignment shall relieve Parent of any of its obligations hereunder, and (ii) any Securityholder may assign its rights, interests and obligations under this Agreement to any Clay Family Member (as defined in the JV Operating Agreement attached as Exhibit A to the Transaction Agreement) that is or agrees to become a party to this Agreement.

Any purported assignment not permitted under this Section 7(h) shall be null and void.

(i)          Remedies.

It is accordingly agreed that the parties shall be entitled to one or more injunctions, temporary restraining orders or other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the Chancery Court of the State of Delaware, without bond or other security being required, this being in addition to any other remedy to which they are entitled at law or in equity.
