                        AUTHORIZATION TO CHARGE ACCOUNT

     This Authorization to Charge Account ("Authorization") is part of the
consideration given to Commercial Money Center, Inc. or its assigns ("CMC") to
induce CMC to enter into Lease Agreement No. K030312 ("the lease") with us.  We
understand that THIS IS A NONCANCELABLE AUTHORIZATION DURING THE TERM OF THE
LEASE.

     The Authorization to charge our account at our bank shall be the same as if
we had personally signed a check to CMC.  This Authorization shall remain in
effect until CMC notifies our bank in writing that wish to end this
Authorization.  CMC will so notify our bank when all sums due and owing to it
pursuant to the Lease have been received by CMC.

     This Authorization is entered into concurrently with the Lease and is
hereby incorporated therein.  If this Authorization, with or without our
knowledge or consent or, by the act of any third party, is in anyway terminated,
stayed, modified, or suspended without the written consent of CMC, such act or
omission shall be deemed a default under terms and provisions of the Lease and
CMC may thereupon exercise any and all rights and remedies as stated in the
Lease.

     A record of your payment shall be included in our bank statement and will
serve as our receipt.  In the event of an error and with the written consent of
CMC, we have the right to reverse any transfer.  However, we must notify our
bank within fifteen days of the date of our bank statement or within forty-five
days after transfer was made.

     We understand and agree that our bank is not responsible for an error in
the amount of any transferred payment.  In the event of such an error, we will
reconcile directly with CMC.

                         IMPORTANT INFORMATION ON YOUR
                          PRE-AUTHORIZED LEASE PAYMENT
                                -A MUST READ!!-

     IN THE EVENT A PAYMENT DEBIT IS NOT HONORED BY YOUR BANK FOR INSUFFICIENT
FUNDS, ACCOUNT CLOSED, PAYMENT STOPPED OR ANY OTHER REASON, AN AUTOMATIC SERVICE
CHARGE OF $10.00 WILL BE ASSESSED AND BILLED TO YOU.

     I (We) hereby authorize our bank to charge our account each month and to
pay CMC the amount shown below.  I (We) have read, understand and agree with the
terms of this Authorization.

     Monthly payments:  $11,013.94 + 0.00 = 11,013.94 due on the 1st of each
month.
