          (a) "Proprietary Information" shall mean all drawings, documents,
     ideas, know-how and other information supplied by one party to another
     (whether disclosed orally, or in documentary form, by demonstration or

recipient only to persons within the recipient's company (including companies
directly or indirectly more than fifty percent (50%) owned or controlled by the
recipient) who are directly concerned in the Proper Use, and shall not be
disclosed to consultants or by the recipient to any other party without the
disclosing party's prior written consent, except for Proprietary Information
that was:

          (a) In the public domain at the time it was disclosed; or
