and (o) upon Lender's reasonable request, appear in and defend any action or
proceeding that may affect Borrower's title to or Lender's security interest

the Collateral; or (b) cause any waste or unusual or unreasonable depreciation
of the Collateral.

                  2.4        INSURANCE. Upon execution of this Agreement,
Borrower will insure the Collateral, with Lender named as a loss payee, in
reasonable form and amounts, with companies reasonably acceptable to Lender, and
against normal risks and liabilities. Borrower will deliver copies of such

disapproving, accepting, preventing, obtaining or failing to obtain any
insurance, incur any liability for or with respect to the amount of insurance
carried, the form or legal sufficiency of insurance contracts, solvency of

respect thereto.

                  2.5        PERFECTION. Borrower represents and warrants to
Lender that subject to the timely filing of such UCC-1 Financing Statements as

Borrower to Lender pursuant to the terms of this Agreement, this Agreement
creates a valid, perfected, and first priority lien against and security
interest in the Collateral, securing the payment of the Obligations, and all
filings and other actions necessary or desirable to perfect and protect such
interest have been duly taken. Borrower further represents and warrants to
Lender that neither the Collateral nor any portion thereof is subject to (or
will be subject to) any lien, encumbrance, or security interest in favor of any
third party that is senior in priority to the lien against and security interest
in the Collateral granted by Borrower to Lender pursuant to the terms of this
Agreement. Borrower represents and warrants to Lender that with respect to any
and all Collateral that Lender sells to Borrower, Lender will have a valid and
perfected first priority lien against and purchase money security interest in
such Collateral.

                  2.6        EXPENSES. Lender may incur expenses in connection
with the retaking, holding or preparing for sale of the Collateral including,
with limitation, reasonable attorneys'

                  2.7        WAIVERS. Borrower waives every right it may have to
require Lender to proceed against any person or to exhaust any Collateral or to
pursue any remedy available to Lender. Borrower waives every defense it may have
arising from Lender's failure to perfect or maintain a perfected security
interest in the Collateral.

                  2.8        TERMINATION OF SECURITY INTERESTS; RELEASE OF
COLLATERAL. Upon payment in full of all Obligations, the security interest
created hereby will terminate. Upon such termination of the security interest or
release of any Collateral, Lender will execute and deliver to Borrower such
documents as Borrower reasonably requests to evidence the termination of the
security interest or the release of such Collateral.

                  2.9        CUMULATIVE RIGHTS. All rights and remedies of
Lender under this Agreement are in addition to all rights and remedies given to
Lender contained in any other agreement, instrument or document or available to
Lender at law or in equity. All such rights and remedies are cumulative and not
exclusive and may be exercised successively or concurrently. No exercise of any
right or remedy will be deemed an election of remedies and preclude exercise of
any other right or remedy.

sale from time to time by announcement at the time and place fixed therefor,
and such sale may, without further notice, be made at the time and place to
which it was so adjourned. To the extent permitted by law, Borrower hereby
specifically waives all rights of redemption, stay, or appraisal which it has
or may have under any law now existing or hereafter enacted.

                           (b)        For the purposes of this Agreement,
Borrower acknowledges and agrees that after an Event of Default, it will be
liable to Lender for all attorneys' fees, consultant's fees, accountants'
fees, expert witness fees, and all actual out-of-pocket expenses incurred by
Lender in connection with any and all of the following: (1) any action taken
by Lender to (A) enforce any of its rights under this Agreement, (B) protect,
preserve, collect, assemble, lease, sell, take possession of, or liquidate
any of the Collateral, or (C) enforce or foreclose upon its security interest
in any of the Collateral; (2) any negotiation and/or documentation of a work
out, refinancing, restructuring, or settlement agreement with Borrower; and
(3) the commencement or defense of, or appearance or intervention in, any
litigation, arbitration proceeding, administrative proceeding, or bankruptcy
case (including but not limited to any adversary proceeding in such case) in
or to which Borrower is a party or party in interest.

Beyond the safe custody thereof, Lender will have no duty with respect to any
Collateral in its possession or control (or in the possession or control of any
agent or bailee) or with respect to


<Page>

any income thereon or the preservation of rights against prior parties or any
other rights pertaining thereto. Lender will be deemed to have exercised
reasonable care in the custody and preservation of the Collateral in its
possession if the Collateral is accorded treatment substantially equal to
that which it accords its own property. Lender will not be liable or
responsible for any loss or damage to any of the Collateral, or for any
diminution in the value thereof, by reason of the act or omission of any
warehouseman, carrier, forwarding agency, consignee or other agent or bailee
selected in good faith by Lender.

                  5.4        APPLICATION OF PROCEEDS. Upon the occurrence and
during the continuance of an Event of Default, the proceeds of any sale of, or
other realization upon, all or any part of the Collateral by Lender will be
applied: first, to all fees, costs and expenses incurred by Lender with respect
to the enforcement of this Agreement; second, to accrued and unpaid interest on
the Obligations; and third, to the principal amount of the Obligations
outstanding. Lender acknowledges and agrees that it will not retain any proceeds
in excess of the amounts necessary to pay in full all of the items described in
the preceding sentence, and will remit promptly to Borrower all of such excess
proceeds, if any.

         6.       MISCELLANEOUS.

Agreement has been represented by independent counsel in the preparation and
negotiation of this Agreement, and this Agreement will be construed according to

that it has full power, authority and legal right to execute, deliver and comply

actions of each of the parties to this Agreement that are necessary or
appropriate for the execution and delivery of and compliance with this Agreement
and such other documents and instruments have been taken. Upon its execution and
delivery, this Agreement will constitute the valid and legally binding
obligation of each of the parties to this Agreement, enforceable against each of

subsequent litigation, arbitration proceeding, controversy or dispute concerning
this Agreement, neither of them will be permitted to offer or introduce into
evidence any oral testimony concerning any oral promises or oral agreements

the parties to this Agreement.

arbitrator who will be a retired judge associated with the San Francisco
regional office of JAMS, and who will be selected by JAMS within five (5)
days of the service of a written request that JAMS select the arbitrator.

SECTION 6.12 IS A MATERIAL INDUCEMENT TO IT TO ENTER INTO THIS AGREEMENT, AND
EACH PARTY IS REASONABLY RELYING UPON THE OTHER PARTY'S REPRESENTATION TO DO
SO.

                           (e)        ARBITRATION HEARING AND AWARD. The
arbitration hearing will be conducted within thirty (30) days of the
appointment of the arbitrator. The arbitration will be conducted in
accordance with the JAMS Rules. The arbitrator's award will be conclusive and

entitled to recover from the adverse party its costs and expenses incurred in
connection therewith including, without limitation, attorneys' fees as

out-of-pocket expenses including, without limitation, expert witness and
consultants' fees. Judgment upon the arbitrator's award may be entered in any
court of competent jurisdiction.
