(g) Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application thereof to any Person or any circumstance, is found by a court or other Governmental Authority of competent jurisdiction to be invalid or unenforceable, the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as would be enforceable.

(h) Specific Performance and Other Remedies.

It is accordingly agreed that, without posting bond or other undertaking, the parties shall be entitled to injunctive or other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any court of competent jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.

The parties hereto further agree that (i) by seeking any remedy provided for in this Section 10(h), a party shall not in any respect waive its right to seek any other form of relief that may be available to such party under this Agreement and (ii) nothing contained in this Section 10(h) shall require any party hereto to institute any action for (or limit such party’s right to institute any action for) specific performance under this Section 10(h) before exercising any other right under this Agreement.

11

(i) No Waiver. The failure of any party hereto to exercise any right, power or remedy provided under this Agreement or otherwise available in respect hereof at law or in equity, or to insist upon compliance by any other party hereto with such party’s obligations hereunder, and any custom or practice of the parties at variance with the terms hereof, shall not constitute a waiver by such party of such party’s right to exercise any such or other right, power or remedy or to demand such compliance.

(j) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflicts of law rules of such state.

The parties hereto agree that any Action seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby (whether brought by any party or any of its Affiliates or against any party or any of its Affiliates) shall be brought in any state or United States federal court located in the State of Delaware, United States, and each of the parties hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such Action and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such Action in any such court or that any such Action brought in any such court has been brought in an inconvenient forum. Process in any such Action may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 10(f) shall be deemed effective service of process on such party.
