          6.10.1  If while payment Obligations are outstanding any item of
Equipment is lost, stolen, destroyed, damaged or seized by a Governmental
Authority (an "Event of Loss"), then, at Borrower's option, either (i) Lender
shall receive from the proceeds of insurance maintained pursuant to Section 6.6,
from any award paid by the seizing Governmental Authority or, to the extent not
received from the proceeds of insurance or award or both, from Borrower, on or
before the next scheduled payment date succeeding such Event of Loss, an amount
equal to the replacement value of the item of Equipment subject to the Event of
which shall be held as additional Collateral for the Loan, or (ii) if no Event
of Default has occurred and is continuing, Borrower may use any such proceeds to
purchase an item of Equipment to replace the item of Equipment which was subject
to the Event of Loss and such replacement Equipment shall become part of the
Collateral.  On the date of receipt by Lender of the amount specified
hereinabove with respect to each such item of Collateral subject to an Event of
Loss, the provisions of this Agreement shall terminate as to such Collateral.
Any proceeds of insurance maintained by Borrower with respect to the Collateral

the election of Borrower, be applied either to the repair or replacement of such
Collateral or, upon Lender's receipt of evidence of the repair or replacement of
the Collateral reasonably satisfactory to Lender, to the reimbursement of
Borrower for the cost of such repair or replacement. All replacement parts and
equipment acquired by Borrower in replacement of Collateral pursuant to this
Section 6.10 shall immediately become part of the Collateral upon acquisition by
Borrower. Borrower shall take such actions and provide such documentation as may
be reasonably requested by Lender to protect and preserve Lender's first
priority security interest and otherwise to avoid any impairment of Lender's
rights under the Operative Documents, in connection with such repair or
replacement.

ARTICLE 7.  CONFIDENTIALITY.

     Lender agrees to hold non-public information received by it in confidence
and shall not disclose such information to third parties except to the extent
any disclosure of such information is required by auditors, lenders, a court of

at the time or in the manner provided in any Operative Document, then at
Lender's sole and absolute discretion, without notice to or demand upon Borrower
and without releasing Borrower from any obligation, covenant or condition in any
Operative Document, Lender may make, perform, observe, take or do the same in
such manner and to such extent as Lender may deem necessary to protect its
security interest in or the value of the Collateral, and Borrower shall be
liable to Lender for all costs and expenses incurred by Lender in connection
therewith.

law and in equity, against Borrower, its successors and assigns, and against

                                      -19-

time of, or received by Lender after, the occurrence of an Event of Default
hereunder) shall be paid to and applied as follows: (a) First, to the payment of
reasonable costs and expenses, including all amounts expended to preserve the
value of the Collateral, of foreclosure or suit, if any, and of such sale and

sale, entry or otherwise, and such proceedings shall have been discontinued or

fail to give such notice to Lender with regard to any such claim or cause of
action, Borrower shall be deemed to have waived, and shall be forever barred
from bringing or asserting such claim or cause of action in any suit, action or
proceeding in any court or before any governmental agency or authority or any
arbitrator. (b) NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED

or lease financing prior to the time that such requests are provided to other

<PAGE>

appropriate to protect and preserve the right, title and interest of Lender in

Lender were the outright owner of the Collateral; provided, however, that the
power of attorney herein granted shall be exercisable only upon the occurrence
