(a) In the event that any part of this Agreement is declared by any court or other judicial or administrative body to be null, void or unenforceable, and all of the other provisions of this Agreement shall remain in full force and effect, with no effect on the validity or enforceability of such other provisions. If any provision of this Agreement, or the application of such provision to any Person or any circumstance, is invalid or unenforceable, (i) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (ii) 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 of such provision, in any other jurisdiction.

9.12 Injunctive Relief.

It is accordingly agreed that BGC Partners shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the performance of terms and provisions of this Agreement in any court referred to in Section 9.1, without proof of actual damages (and Cantor hereby waives any requirement for the securing or posting of any bond in connection with any such remedy), this being in addition to any other remedy to which BGC Partners is entitled at law or in equity. Cantor further agrees not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, or to assert that a remedy of monetary damages would provide an adequate remedy for any such breach.
