MULTIPLE SITE INSTALLATION FEE:         $**** PER ADDITIONAL SITE LOCATION.

SECTION 9. ONGOING SUPPORT FEES; VOLUME REBATES. As additional consideration for
our initial and continuing marketing, technical and Program support, you agree

                                       2
<PAGE>

ongoing support fee equal to ****% of the total discount fees charged or taken
by you in each subsequent month with respect to "ongoing purchases" of
receivables from each CashFlow Manager customer. As used herein, the term
"Initial Balance" purchase means the first purchase of receivables from a
CashFlow Manager Customer (or the first 30 days' receivables acquired by you if
you either (i) acquire less than all of the CashFlow Manager customer's
receivables existing on the date of the first purchase of receivables, or (ii)
if such CashFlow Manager customer has no existing receivables which will be
purchased by you until after the date of the first purchase of receivables).
"Ongoing purchases" means purchases of receivables from a CashFlow Manager
Customer subsequent to the Initial Balance purchase.

SUPPORT FEE REBATES. We agree to pay you a marketing rebate based upon the
monthly volume levels of ongoing receivable purchases made by you from your
CashFlow Manager customers. These volume levels and the amount of the rebate
percentage applicable to each volume level as applied to the discount fees
charged or taken by you in a specific month are as follows:

LEVEL   AMOUNT OF RECEIVABLES PURCHASED    REBATE PERCENTAGE* (OF DISCOUNT FEE)
--------------------------------------------------------------------------------

I             $****        -         $****.......................... ****%
II            $****        -         $****...........................****%
III           $****        +              ...........................****%

* The net effective ongoing support fee rate at these levels is **%, **% and
**%, respectively.

These volume rebate percentages shown above are applied separately to each of
the specific volume levels to which they relate (e.g., the rebate percentage for
receivable purchases between $**** and $**** is ****% regardless of the total
receivables purchased in that month, etc.). These marketing rebates will be
processed by us approximately forty-five (45) days after the close of the
calendar month to which the rebate relates, and payable by us to you no more
than sixty (60) days beyond the close of the calendar month to which the rebate
relates. The rebates will be applicable to: (1) all ongoing support fees which
are normally processed and invoiced during a calendar month which (2) are paid
to us no later than twenty-five (25) days following the invoice date. Rebates
will not be given with respect to any ongoing support fees which are paid to us
more than 25 days beyond the invoice date.

SECTION 10. REPORTING AND PAYMENT OF ONGOING SUPPORT FEES. You agree to report
to us each month, on forms supplied by us, the amount of receivables purchased
during the preceding month, and remit by check the fees due to us under this
agreement. All ongoing support fees will be due and payable within twenty-five
(25) days of the invoice date. Amounts which are due and not paid to us as
provided in this agreement will thereafter bear interest at the rate of eighteen
percent (18.0%) per annum.

SECTION 11. TERM OF AGREEMENT, TERMINATION . This agreement will be effective on
the date of execution by us, and will be for an initial term of five (5) years
(the "Initial Term"). At the end of the Initial Term, and on each anniversary
date thereafter, this agreement will automatically extend for an additional year
beyond the Initial Term, or renewal term, unless we or you give written notice
to the other of non-extension at least sixty (60) days prior to the expiration
date of the Initial Term, or renewal term of this agreement. From and after such
effective date of termination, for any reason, you shall cease processing sales
through the Program, shall cease displaying the service marks, symbols, and
names related to the Program, and shall promptly return to us all materials
relating to the Program. All of your obligations incurred or existing under this
agreement as of the date of termination shall survive such termination,
including those set forth in Section 15 below.

This agreement may also be terminated during the Initial Period, as set forth
below.

INITIAL PERIOD. The first twelve (12) months of the Initial Term of this
agreement will be deemed the "Initial Period." If you have not purchased of a
minimum of $100,000 in Initial Balance purchases of receivables (as defined in
this agreement) during the Initial Period, we agree that you will have the right
and option either to: (i) terminate this agreement; or (ii) to continue the
Program without a termination of this agreement. To terminate this agreement,
you must give us written notice of your election to terminate within thirty (30)
days following the expiration of the Initial Period. In the event you give us

                                       3
<PAGE>

notice of termination under these circumstances, this agreement will terminate
on the date specified in the notice. If you do not give us written notice under
these circumstances, we will continue the Program without a termination of this
agreement. Any ongoing support fees which are outstanding at the time of a
termination will be immediately due and payable to us.

EARLY TERMINATION AFTER THE INITIAL PERIOD. After the Initial Period expires, we
agree that you will have the right to terminate this agreement by giving us
ninety (90) days prior written notice of termination, subject to the remaining
provisions of this Section and Section 15. In the event you terminate this
agreement prior to the expiration of the Initial Term or a renewal term (except
a termination which arises out of our uncured default), any ongoing support fees
which are outstanding at the time of a termination and all other fees which have
not been paid previously by you will be due and payable 25 days after the date
of termination specified in your notice.

ONGOING PURCHASE FEE OBLIGATIONS AFTER EXPIRATION OR TERMINATION. As additional
consideration for the license and services we provide in connection with the
Program, you agree to pay an ongoing purchase fee ("OP Fee") with respect to
each CashFlow Manager customer for a period of twenty-four (24) months following
the expiration or termination of this agreement if you continue to offer an
accounts receivable financing program of a nature similar to CashFlow Manager
("replacement program") to such customer. So long as the OP Fee is payable under
these circumstances, you agree to report to us each month, on forms supplied by
us, the amount of receivables purchased during the preceding month, and remit by
check the fees due to us under this section. All OP Fees will be due and payable
on or before the 25th day of each month for purchases made in the preceding
month.

We agree that you will have no OP Fee obligation if you do not offer, or once
you discontinue to offer, your replacement program to such CashFlow Manager
customer. We also agree that you will have no OP Fee obligation with respect to
new customers added to your replacement program following a termination or
expiration of this agreement, or if the termination of this agreement arises out
of our uncured default in obligations to you under this agreement. The OP Fee
provided for in this section shall be calculated in the same manner as the
ongoing support fees provided for in Section 9, including any applicable volume
rebate provisions.

EARLY TERMINATION BY BREACH. If either party materially defaults in the
performance of any obligation under this agreement, and this default continues
for a period of thirty (30) days after written notice is given by the
non-defaulting party, then the non-defaulting party will have the right, at its
option, to terminate this agreement by giving written notice of such
termination.
