          have an adequate remedy at law in the event of a violation by the
          receiving Party of such obligations.  The receiving Party agrees and
          consents that the disclosing Party shall be entitled, in addition to
          all other rights and remedies to which the disclosing Party may be
          entitled, to have a decree of specific performance or an injunction
          issued requiring any such violation to be cured and enjoining all
          persons involved from continuing the violation.  The existence of any
          claim or cause of action that the receiving Party or any other person
          may have against the disclosing Party shall not constitute a defense
          or bar the enforcement of this Section 17.  The receiving Party
          acknowledges that the restrictions in this Section 17 are reasonable
          and necessary to protect legitimate business interests of the
          disclosing Party.
