(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 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.

Each of the parties agrees that it shall not oppose the granting of an injunction, specific performance, and 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 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.

(g) This Agreement shall be governed by, and construed in accordance with, the Laws of the State of New York applicable to contracts executed in and to be performed in that State without giving effect to principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of Laws of another jurisdiction.

The parties hereto hereby (i) submit to the exclusive jurisdiction of federal or state courts within the State of New York for the purpose of any Action arising out of or relating to this Agreement brought by any party hereto, and (ii) irrevocably waive, and agree 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 transactions contemplated hereunder 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 or proceeding 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 7(b).

No failure or delay by a party in exercising any right hereunder shall operate as a waiver thereof. No waivers of or exceptions to any term, condition, or provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term, condition, or provision.

(o) Each party shall be responsible for its own fees and expenses (including the fees and expenses of investment bankers, accountants and counsel) in connection with the entering into of this Agreement, the performance of its obligations hereunder and the consummation of the transactions contemplated hereby; provided, that in the event of any Action arising out of or relating to this Agreement, the non-prevailing party in any such Action will pay its own expenses and the reasonable documented out-of-pocket expenses, including reasonable attorneys’ fees and costs, reasonably incurred by the prevailing party.
