(d) Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any 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 hereto. 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 an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

(e) Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement.

(g) Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Indiana, regardless of the Laws that might otherwise govern under applicable principles of conflicts of law thereof.

(h) Assignment.

Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

(i) Enforcement. The transactions contemplated by this Agreement are unique and the parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, each of the parties hereto acknowledges and agrees that, in addition to all other remedies to which it may be entitled, each of the parties hereto is entitled to a decree of specific performance, provided that such party hereto is not in material default or breach hereunder. The parties hereto agree that, if for any reason a party hereto shall have failed to perform its obligations under this Agreement, then the party hereto seeking to enforce this Agreement against such nonperforming party under this Agreement shall be entitled to specific performance and injunctive and other equitable relief, and the parties hereto further agree to waive any requirement for the securing or posting of any bond in connection with the obtaining of any such injunctive or other equitable relief. This provision is without prejudice to any other rights that any party hereto may have against another party hereto for any failure to perform its obligations under this Agreement.

(j) Jurisdiction. Any suit, action or proceeding 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 or thereby may be brought in any federal or state court located in the State of Indiana, and each of the parties hereby consents to the jurisdiction of such courts (and of the

appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by Law, any objection which it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding which is brought in any such court has been brought in an inconvenient forum. Process in any such suit, action or proceeding 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 by U.S. registered mail to such party’s address set forth herein shall be deemed effective service of process on such party; provided that nothing herein shall affect the right of any party to serve legal process in any other manner permitted by Law. The consent to jurisdiction set forth in this Agreement shall not constitute a general consent to service of process in the State of Indiana and shall have no effect for any purpose except as provided in this Agreement. The parties hereto agree that final judgment in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.
