12.          Miscellaneous.

12.1         Severability. If any term, provision, agreement, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, agreements, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the obligations contemplated hereby is not affected in any manner materially adverse to any party hereto.

6

No party to this Agreement may assign or delegate, by operation of law or otherwise, all or any portion of its rights, obligations or liabilities under this Agreement without the prior written consent of the other parties to this Agreement. Any purported assignment in violation of this Section 12.2 shall be void.

12.3         Amendment. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

12.4         Specific Performance; Injunctive Relief.

Each of the parties agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief 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 of this Agreement and to enforce specifically the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.

12.5         Notices.
