            documents and other evidence thereof. Consultant acknowledges that
            all Confidential Information, whether prepared by Consultant or

            the Company, and the Company's officers, directors and shareholders

            deficiencies, including, without limitation, interest, penalties and
            reasonable attorney fees and costs, that the Company may incur or
            suffer and that arise, result from or are related to any breach or

            warranties and agreements contained in this Agreement. Consultant is

            Company's Right to Assign. Consultant's rights and benefits under

      18.   No Third Party Beneficiary. Nothing in this Agreement, whether

            hereunder.

      19.   Severability. If any term or provision of this Agreement is found to
            be invalid, illegal or unenforceable under present or future laws
            effective during the term of this Agreement, then and, in that event
            (i) the performance of the offending term or provision (but only to

            shall be excused as if it had never been incorporated in to this
            Agreement, and, in lieu of such excused provision as may be possible
            and be legal, valid and enforceable, and (ii) the remaining part of
