  15.   Amendments, Modifications and Waivers:  No delay or failure by either
        party to exercise or enforce at any time any right or provision of this
        Agreement will be considered a waiver thereof or of such party's right
        thereafter to exercise or enforce each and every right and provision of
        this Agreement.  No single waiver will constitute a continuing or
        subsequent waiver.  No waiver, modification or amendment of any
        provision of this Agreement will be effective unless it is in writing
        and signed by the parties, but it need not be supported by
        consideration.

  16.   Equitable Relief:  Because each party will have access to and become
        acquainted with confidential and proprietary information of the other,
        the unauthorized use of disclosure of which would cause irreparable harm
        and significant injury which would be difficult to ascertain and which
        would not be compensable by damages alone, each party agrees that the
        other party will have the right to enforce this Agreement and any of its
        provisions by injunction, specific performance or other equitable relief
        without prejudice to any other rights and remedies that it may have for
        breach of this Agreement.
