                                  MISCELLANEOUS

      7.1 Limitation on the Secured Party's Duty in Respect of Collateral. The
Secured Parties shall be deemed to have acted reasonably in the custody,
preservation and disposition of any of the Collateral if they take such action
as the Debtor requests in writing, but failure of the Secured Parties to comply

and no failure of the Secured Parties to do any act not so requested shall be
deemed a failure to act reasonably.

      7.2 Reinstatement. This Security Agreement shall remain in full force and
effect and continue to be effective should any petition be filed by or against

or make an assignment for the benefit of creditors or should a receiver or
trustee be appointed for all or any significant part of the Debtor's property
and assets, and shall continue to be effective or be reinstated, as the case may
be, if at any time payment and performance of the Secured Obligations, or any
part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or
must otherwise be restored or returned by any obligee of the Secured
Obligations, whether as a "voidable preference," "fraudulent conveyance," or
otherwise, all as though such payment or performance had not been made. In the


                                       8
<PAGE>

returned, the Secured Obligations shall be reinstated and deemed reduced only by
such amount paid and not so rescinded, reduced, restored or returned.

be waived, amended, supplemented or otherwise modified with the written consent
of the Company and the Secured Parties holding at least 75% in aggregate
principal amount of the Notes issued in the Offering.

      7.7 No Waiver; Remedies Cumulative. No failure or delay on the part of the
Secured Parties in exercising any right, power or privilege hereunder and no
course of dealing between the Debtor shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. A waiver by the Secured Parties of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Secured Parties would otherwise have on any future
occasion. The rights and remedies herein expressly provided are cumulative and
may be exercised singly or concurrently and as often and in such order as the
Secured Parties deem expedient and are not exclusive of any rights or remedies
which the Secured Parties would otherwise have whether by security agreement or
now or hereafter existing under applicable law. No notice to or demand on the
Debtor in any case shall entitle the Debtor to any other or further notice or
demand in similar or other circumstances or constitute a waiver of the rights of
the Secured Parties to any other or future action in any circumstances without
notice or demand.

      7.8 Termination; Release. When the Secured Obligations have been
indefeasibly paid and performed in full this Security Agreement shall terminate,
and the Secured Parties, at the request and sole expense of the Debtor, will
execute and deliver to the Debtor the proper instruments (including UCC
termination statements) acknowledging the termination of this Security
Agreement, and will duly assign, transfer and deliver to the Debtor, without
recourse, representation or warranty of any kind whatsoever, such of the
Collateral as may be in the possession of the Secured Parties and has not
theretofore been disposed of, applied or released.
