Collateral, the Patent Collateral and the Trademark Collateral. Additionally,
upon such satisfaction, the Collateral Agent shall reasonably cooperate with any
efforts made by an Obligor to make of record or otherwise confirm such
satisfaction including, but not limited to, the release and/or termination of
this Agreement and any security interest in, to or under the subject collateral.

4. The security interest in this Agreement has been granted as a supplement to,
and not in limitation of, the security interest granted to the Collateral Agent
under the Security Agreement. The Security Agreement (and all rights and
remedies of the Collateral Agent) shall remain in full force and effect in
accordance with its terms. The rights and remedies of the Collateral Agent with

provisions of which are incorporated herein by reference.
