         exclusively to the benefit of the other party.

      obligation of confidence to the disclosing party; or

(d)   which is required to be produced by law or regulation or under order of

                                        10


      receiving party cooperate with the disclosing party in seeking to resist 
      or narrow such request or to secure assurances that the Confidential 
      Information so disclosed would be kept confidential.

         During the term of this Agreement and at all times thereafter, the 
receiving party shall hold in strictest of confidence and shall never 
disclose, transfer, convey or make accessible to any person any Confidential 
Information of the disclosing party. The receiving party agrees not to use 
the Confidential Information of the disclosing party except to the extent 
necessary to perform its obligations under this Agreement, and agrees not to 
allow such Confidential Information to be used for the benefit of anyone 
other than the disclosing party. The receiving party agrees to take 
reasonable precautions to prevent receiving party's employees, 
representatives, agents and others from disclosing or appropriating for their 
own use any Confidential Information of the disclosing party.
