for which it was intended,  and (z) must be returned to the disclosing  Party or

the  request  of the  disclosing  Party,  the  receiving  Party  will  furnish a
certificate of an officer of the receiving  Party  certifying  that  Proprietary
Information  not  returned  to  disclosing  Party  has been  destroyed.  For the
purposes hereof, Proprietary Information does not include information which:

          (i) has been or may in the future be published or is now or may in the

in the event of a breach or threatened breach of this Contract, without limiting
any other rights and remedies  specified  herein,  an  injunction  may be sought

Party  represents and warrants that it has the right to disclose all Proprietary
Information which it has disclosed to the other Party pursuant to this Contract,
and each Party agrees to indemnify  and hold  harmless the other from all claims
by a third  party  related to the  wrongful  disclosure  of such  third  party's
Proprietary  Information.  Otherwise,  neither Party makes any representation or
warranty, express or implied, with respect to any Proprietary Information.
