The Consultant acknowledges that the Company from time to time has in its possession information (including product and development plans and specifications) which represent information which is claimed by others to be proprietary and which the Company has agreed to keep confidential. The Consultant agrees that all such information shall be Confidential Information for purposes of this Agreement.

provision. No waiver of any breach of or non-compliance with this Agreement shall be held to be a waiver of any other or subsequent breach or non-compliance.

(g)     Remedies. The Consultant recognizes that money damages alone would not adequately compensate the Company in the event of breach by the Consultant of this Agreement, and the Consultant therefore agrees that, in addition to all other remedies available to the Company at law, in equity or otherwise, the Company shall be entitled to injunctive relief for the enforcement hereof.

If, after application of the preceding sentence, any provision of this Agreement shall be determined to be invalid, illegal or otherwise unenforceable by a court of competent jurisdiction, the validity, legality and enforceability of the other
