under the Uniform Commercial Code. Pledgor acknowledges that the Note remains a
full recourse obligation of Pledgor.

         4. Pledgor warrants and represents to the Company that upon delivery of
the Pledged Stock to the Company, this Stock Pledge Agreement creates and grants
a valid lien on and perfected security interest in the Pledged Stock, subject to
