Obligations. All acts done under the foregoing authorization are hereby ratified
and approved and neither the Secured Party nor any designee or an agent thereof

judgment or for any mistake of fact or law; provided, that the Secured Party
shall not be relieved of liability to the extent its or its agent's or
designee's act, error or mistake constituted gross negligence or willful
misconduct. This power of attorney being coupled with an interest is irrevocable
while any Obligations shall remain unpaid.

7. Care of Collateral. The Secured Party shall have the duty to exercise
reasonable care in the custody and preservation of any Collateral in its

property owned by them, and, with respect to the Secured Party's custody and
preservation of any of the Collateral in their possession, the Debtor releases
the Secured Party from, and agree to indemnify, defend, and hold harmless the
Secured Party with respect to, any third party claims, causes of actions, and
demands at any time arising out of or with respect to the Secured Party's

hereof. All amounts payable by the Debtor under this Section shall be due upon
demand and shall be part of the Obligations. The Debtor's obligations under this
Section shall survive the termination of this Agreement and the discharge of the
Debtor's other obligations hereunder.

         (a) The Debtor agrees to indemnify, reimburse and hold the Secured
Party and its successors, assigns, employees, officers, directors, agents,
attorneys and servants (collectively, "Indemnitees") harmless from and against
any and all liabilities, obligations, damages, injuries, penalties, claims,
demands, actions, suits, judgments and any and all reasonable costs and expenses
(including, without limitation, reasonable attorneys' fees and expenses) of
whatsoever kind and nature imposed on, asserted against, or incurred by any of
the Indemnitees, in any way
<PAGE>

relating to or arising out of this Agreement or in any other way connected with
the administration of the transactions contemplated hereby or the enforcement of
any of the terms hereof, or the preservation of any rights hereunder, or in any
way relating to or arising out of the manufacture, processing, ownership,
ordering, purchase, delivery, testing, control, lease, possession, operation or
other disposition or use of the Collateral by the Indemnitees (including,
without limitation, latent or other defects, whether or not discoverable);
provided, that the Debtor shall have no obligation to an Indemnitee hereunder to
the extent that such indemnified liabilities arise from the gross negligence or
willful misconduct of such Indemnitee. Upon written notice by any Indemnitee of
the assertion of such a liability, obligation, damage, injury, penalty, claim,
demand, action, judgment or suit, Debtor shall assume full responsibility for
the defense thereof. If any action, suit or proceeding arising from any of the
foregoing is brought against any Indemnitee, Debtor shall, if requested by such
Indemnitee, defend such action, suit or proceeding. Each Indemnitee shall,
unless any other Indemnitee has made the request described in the preceding
sentence and such request has been complied with, have the right to employ its
own counsel (or internal counsel) to investigate and control the defense of any
matter covered by the indemnity set forth in this Section, and the fees and
expenses of such counsel shall be paid by the Debtor; provided that, only to the
extent no conflict exists between and among the Indemnitees as reasonably
determined by the Indemnitees, the Debtor shall not be obligated to pay the fees
and expenses or more than one counsel for all Indemnitees as a group with

Debtor under this Section are unenforceable for any reason, the Debtor hereby
agrees to make the maximum
<PAGE>

contribution to the payment and satisfaction of such obligations that is
permissible under applicable law.

         (c) Survival. The obligations of the Debtor contained in this Section
shall survive the termination of this Agreement and the discharge of the
Debtor's other obligations hereunder. 10. Waivers. No act, omission or delay by
the Secured Party or course of dealing between the Secured Party and the Debtor
shall constitute a waiver of the rights and remedies of the Secured Party
hereunder. No single or partial waiver by the Secured Party of any Event of
Default or right or remedy which it may have shall operate as a waiver of any
other Event of Default, right or remedy or of the same Event of Default, right
or remedy on a future occasion. The Debtor hereby waives presentment, notice of
dishonor and protest of all instruments included in or evidencing any
Obligations or Collateral, and all other notices and demands whatsoever (except
as expressly provided herein).
