         2. Assignor covenants that, until all of the Obligations shall have

Assignment, without the Assignee's prior written consent.

         3. Assignor covenants that if, before the Obligations shall have been
satisfied in full, Assignor shall obtain rights to any additional registered
trademarks or servicemarks, or become entitled to the benefit of any
registration applications for trademarks or servicemarks, the provisions of this
Assignment shall automatically apply thereto and Assignor shall give to the
Assignee prompt notice thereof in writing.

action, proceedings, judgments and liabilities, including reasonable attorneys'
fees incurred in litigation or otherwise assessed, incurred or sustained by or
against Assignee's Indemnified Parties or any of them with respect to or arising
out of or in any way connected with this Assignment.

         5. Assignor authorizes the Assignee to modify this Assignment by
amending Schedule A to include any future trademarks, servicemarks, or trademark
or servicemark applications of which Assignor may acquire an interest.

         6. At such time as Borrower shall completely and finally satisfy all of
the Obligations, the Assignee shall execute and deliver to Assignor all deeds,
assignments and other instruments as may be necessary or proper to re-vest in
Assignor full title to the Trademarks, subject to any disposition thereof which
may have been made by the Assignee pursuant to the Security Agreement.

         IN WITNESS WHEREOF, Assignor has caused this Conditional Trademark
Assignment to be duly executed by its duly authorized officer as of the date
first set forth above.
