(c) The Consultant acknowledges and agrees that, because the legal remedies of the Company may be inadequate in the event of a breach of, or other failure to perform, any of the covenants and obligations set forth in this Section, the Company may, in addition to obtaining any other remedy or relief available to it (including without limitation, consequential and other damages at law), enforce this Section by injunction and other equitable remedies. (d) The parties agree that the provisions set forth in this Section, including without limitation as to duration and geographic scope, are reasonable to protect the legitimate interests of the Company. The provisions of this Section are severable, and in the event that any provision hereof should, for any reason, be held invalid or unenforceable in any respect, it shall not invalidate, render unenforceable or otherwise affect any other provision hereof, and such invalid or unenforceable provision shall be construed by limiting it so as to be valid and enforceable to the maximum extent compatible with, and possible under, applicable law. 6 7 8.
