event of a conflict between the terms of this Addendum and the terms of the AWF,
the terms of this Addendum will control in determining the agreement between IBM
Credit and Customers.

         (b)  Exhibit A is incorporated herein. IBM Credit may modify Exhibit A
from time to time by providing Customers with a new Exhibit A. Any such new
Exhibit A shall be effective as of the date specified in the new Exhibit A.
Customers will have accepted the new Exhibit A if a Customer does not notify IBM
Credit in writing of its rejection of the new Exhibit A within thirty (30) days
of the date IBM Credit mails any such new Exhibit A to Customers. In the event
any Customer rejects a new Exhibit A, IBM Credit shall have no further
obligation under this Addendum to make loans or advances or other financial
accommodations to Customers effective on the earlier of (i) the date of the
written rejection or (ii) the thirty-first day after IBM Credit mailed to
Customers the new Exhibit A which was not accepted by a Customer, and all of
Customers’ FPP Outstanding Indebtedness to IBM Credit shall be due and payable
in its entirety in accordance with the then prevailing terms. Only one Exhibit
A, the one with the most recent Effective Date, shall be in force at any time
(“Current Exhibit A”).

         (c)  Any Addendum to the AWF for the Extended Scheduled Payment Program
or Large Sale Financing Option executed by any Customer and IBM Credit prior to
this Addendum is hereby superseded by this Addendum and terminated.

2.2   General Description of Credit Offerings.

Customers may extend the due date for repayment of advances from IBM Credit for
the purchase of Products (“Product Advances”) for the period set forth in
Exhibit A hereto (the “Financing Period”).

Advance Option, the Payment Reschedule Option and the Working Capital Option
described in Section 5 of this Addendum.

Page 3 of 19

--------------------------------------------------------------------------------

 

2.3   Maximum Allowable Indebtedness.

         Customers’ Total Outstanding Indebtedness shall at no time exceed an
amount (the “Maximum Allowable Indebtedness”) equal to the lesser of: (a) the
amount set forth in Exhibit A as the “FPP Credit Line”, or (b) Customers’ Total
Qualifying Collateral Value.

2.4   Available Credit.

         The maximum amount which Customers may borrow under this Addendum in
any given instance (“Available Credit”) shall be equal to (a) the Maximum
Allowable Indebtedness, less (b) Customers’ Total Outstanding Indebtedness.

2.5   Shortfall Amount.

         If at any time the amount of Customers’ Total Outstanding Indebtedness
exceeds the amount of Customers’ Maximum Allowable Indebtedness, Customers agree
to pay immediately to IBM Credit an amount equal to such excess (“Shortfall
Amount”) upon the earliest to occur of (a) demand for payment by IBM Credit, (b)
the delivery of Customers’ Collateral Report, delivered in accordance with
Paragraph 7.1, indicating such Shortfall Amount or (c) any Customer’s
independent determination of such Shortfall Amount.

2.6   Shortfall Transaction Fee.

         IBM Credit will charge Customers a fee (“Shortfall Transaction Fee”)
for each occurrence of a Shortfall Amount unless Customers have timely paid IBM
Credit the amount of such Shortfall Amount in accordance with Paragraph 2.5.
Shortfall Transaction Fees are calculated by multiplying the Shortfall Amount
times the rate specified in Exhibit A.

2.7   Calculation of Financing Charges and Delinquency Fee.

         All financing charges and the Delinquency Fee provided for herein are
computed on the basis of an actual-day, 360-day year and are calculated by
multiplying the applicable period rate for the billing period times the
applicable Average Daily Balance of Customers’ FPP Outstanding Indebtedness
during said period. The “Average Daily Balance” of Customers’ FPP Outstanding
Indebtedness shall equal the sum of the outstanding principal balances as of
each day during the billing period divided by the number of days in the billing
period. The financing charges and the Delinquency Fee shall accrue at the lesser
of (a) the applicable per annum rate specified in Exhibit A, or (b) the highest
rate of interest from time to time permitted by applicable law. Any amount
received from Customers in excess of the highest rate of interest from time to
time permitted by applicable law shall be considered reductions to principal to
the extent of such excess. The financing charges and the Delinquency Fee shall
be based upon floating rates which shall be adjusted as of the first day of each
month based upon the prevailing Prime Rate in effect as of the last day of the
immediately preceding month.

2.8   Delinquency Fee.

         In the event any Customer is delinquent in making any payment to IBM
Credit when due hereunder, IBM Credit will charge a fee (“Delinquency Fee”) to
Customer at the per annum rate specified in Exhibit A, based on the Average
Daily Balance of the delinquent amount from the original due date of the
delinquent payment to the date of payment. Customers shall pay such fee to IBM
Credit as specified and set forth in its monthly billing statement.

2.9   FPP Application Processing Fee.

         IBM Credit will charge a one-time fee to Customers, in an amount
specified by IBM Credit in Exhibit A, and Customers shall pay such fee to IBM
Credit when invoiced by IBM Credit. Such fee shall not be deemed to be an
origination or commitment fee.

Page 4 of 19

--------------------------------------------------------------------------------

 

2.10   FPP Monthly Service Fee.

         IBM Credit will charge a flat fee to Customers, in the amount specified
by IBM Credit in Exhibit A. This fee will be set forth in Customers’ monthly
billing statement from IBM Credit and will be due in accordance with the terms
stated on the monthly billing statement. Such fee shall not be deemed to be an
origination or commitment fee.

2.11   Statement of Transaction.

         In accordance with the terms of the AWF, IBM Credit will send the
requesting Customer a Statement of Transaction notifying such Customer of each
advance under this Addendum. Upon receipt of such Statement of Transaction,
Customers shall be considered to have acknowledged the advance in the amount
indicated on the Statement of Transaction unless such Customer notifies IBM
Credit, in writing, of any correction or objection claimed within seven (7)
business days after such Statement of Transaction is delivered to Customers by
IBM Credit.

2.12   Billings.

         IBM Credit shall send to Customers, at monthly or other intervals, a
statement of all amounts, including principal, accrued financing charges, fees
and costs due and not paid with respect to this Addendum. All such amounts shall
be due and payable in accordance with the terms of such billing statement.
Customers shall be considered to have acknowledged as due such amounts indicated
on any such statement unless Customers object to IBM Credit in writing, within
seven (7) business days after such statement is delivered to Customers by IBM
Credit.

2.13   Place of Payment.

         All payments of sums due from Customers to IBM Credit shall be
delivered to IBM Credit at the address first above written, or at such other
address as IBM Credit may from time to time, in writing, designate.

2.14   Prepayment.

         Customers may elect, at any time, without premium or penalty to prepay
all or part of the principal amount outstanding as IBM Product Advances or under
an FPP Option. Customers will indicate to IBM Credit, in its remittance advice
report, which amounts are to be prepaid (“PrePayments”).

Section 3.0   FPP Provisions

3.1   Product Advances.

         Provided that Customers have adequate Available Credit and provided
that no Event of Default has occurred under the Agreement, pursuant to the FPP
Addendum, IBM Credit shall advance funds for the account of the applicable
Customer in payment of invoice rendered to such Customer for such Customer’s
authorized purchases of Products. Each such advance shall be deemed to be a
Product Advance. Confirmation of each such advance shall be reflected in a
Statement of Transaction which shall identify the date upon which an advance is
made; said date shall be described in the Statement of Transaction as the “Date
of Note”.

3.2   FPP Financing Charge.

No finance charge shall accrue on any Product Advance during the No Charge
Financing Days, if any, applicable to such Product Advance. Each Product Advance
shall be due and payable on the Common Due Date for such Product Advance.
Customers may, at their option, repay a Product Advance by requesting IBM Credit
to apply all or any part of the principal amount of a WCO Advance to the

Page 5 of 19

--------------------------------------------------------------------------------

 

outstanding Product Advance. Customers’ request for such application shall be
made in accordance with Section 4.3. When so requested and subject to the terms
and conditions of this Addendum, IBM Credit shall apply the amount so requested
to the amounts due in respect of the outstanding Product Advances. Nothing
contained herein shall relieve Customers of their obligation to repay Product
Advances when due. Each Product Advance shall accrue a finance charge on the
Average Daily Balance thereof from and including the first (1st) day following
the end of the No Charge Financing Days, if any, for such Product Advance, or if
no such No Charge Financing Days shall be in effect, from and including the Date
of Note for such Product Advance, in each case, to and including the date such
Product Advance shall become due and payable in accordance with the terms of
this Addendum, at a per annum rate equal to the lesser of (a) the finance charge
set forth in Exhibit A to this Addendum as the “FPP Financing Charge” and (b)
the highest rate from time to time permitted by applicable law.

         In addition, for any Product Advance with respect to which No Charge
Financing Days shall not be in effect, Customers shall pay a Free Financing
Period Exclusion Fee for such Product Advance multiplied by the rate set forth
in Exhibit A. Such fee shall be due and payable on the Common Due Date for such
Product Advance. If it is determined that amounts received from Customers were
in excess of the highest rate permitted by law, then the amount representing
such excess shall be considered reductions to principal of Advances.

3.3   Repayment of Product Advances.

         The Financing Period specified in Exhibit A shall commence to run on
the Date of Note applicable to each Product Advance. At the expiration of the
Financing Period for each Product Advance, repayment of the total amount of such
advance shall be due to IBM Credit on the date determined as follows: If the
expiration of the Financing Period occurs on a date from: (i) the first through
the tenth of a month, then payment shall be due on the fifth day of such month;
(ii) the eleventh through the twentieth of the month; then payment shall be due
on the fifteenth day of such month; and (iii) the twenty-first through the
thirty-first of the month, then payment shall be due on the twenty-fifth date of
such month. Said dates are referred to as “Common Payment Due Dates”.

         Customers hereby acknowledge that IBM Credit shall have the right, in
accordance with the terms of the AWF, to apply and reapply any Product Advance
payments, other than PrePayments, to any Product invoices or Product Advance
payments due, as IBM Credit may deem advisable, notwithstanding any entry by IBM
Credit upon its books and records.

Section 4.0   FPP Options

         IBM Credit reserves the right, in its sole discretion, to amend or
terminate any FPP Option requested by Customers and approved by IBM Credit at
any time upon thirty (30) days written notice. All advances made by IBM Credit
prior to the effective date of any proposed termination or amendment of any FPP
Option will not be impaired by such proposed termination or amendment.

4.1   Takeout Advance Option.

         Provided that Customers have adequate Available Credit and provided
that no Event of Default has occurred under the Agreement, pursuant to the
Takeout Advance Option, Customers may in writing request an advance (“Takeout
Advance”) in an amount sufficient to pay off and discharge all remaining
indebtedness it has with other lenders to meet IBM Credit’s requirements for
acceptance of this Addendum. IBM CREDIT MAY, IN ITS SOLE DISCRETION, PROVIDE
SUCH TAKEOUT ADVANCE.

         Customers must complete all of the IBM Credit required documents

Page 6 of 19

--------------------------------------------------------------------------------

 

         The Takeout Advance shall accrue a finance charge during the period
from the date such advance is made to maturity at the per annum rate specified
in Exhibit B as the “FPP Takeout Advance Financing Charge”. From and after
maturity, the delinquent portion of the Takeout Advance shall accrue a
Delinquency Fee in accordance with Paragraph 2.8 hereof.

         Customers shall repay the Takeout Advance according to the repayment
schedule set forth in Exhibit B. All amounts due and unpaid will be set forth in
Customers’ monthly billing statement.

4.2   Payment Reschedule Option.

         Provided that Customers have adequate Available Credit and provided
that no Event of Default has occurred under the Agreement, pursuant to the
Payment Reschedule Option (“PRO”), a Customer may request IBM Credit to provide
a credit advance to repay, all or any part of any Product Advance when due. Such
Customer shall provide IBM Credit with a written request (“Reschedule Request”)
for a PRO advance (“PRO Advance”) for periods of 10 day increments (“PRO Term”)
up to the maximum approved term set forth in Exhibit A (“Maximum PRO Term”).

         The Rescheduled Request must state the PRO Advance amount requested,
and the month, day and year of the Common Payment Due Date, as set forth in
Customers’ applicable monthly billing statement from IBM Credit, or the Product
Advance or part thereof to be rescheduled. Each Reschedule Request is subject to
IBM Credit’s written approval and shall not exceed the Maximum PRO Term. IBM
CREDIT MAY, IN ITS SOLE DISCRETION, PROVIDE SUCH PRO ADVANCE.

         If a Reschedule Request is approved by IBM Credit, the PRO Term shall
commence on the Common Payment Due Date for the Product Advance or part thereof
being paid by the PRO Advance and shall end on the last day of the approved PRO
Term. Payment for the PRO Advance shall be due on the last day of the PRO Term.
Payments due for PRO Advances are not eligible for rescheduling under the PRO.

         Customers cannot use the PRO to reschedule any Product Advance or part
thereof on any Common Payment Due Date on which any Customer will take a
discount offered by IBM Credit for invoice amounts paid in full within fifteen
(15) days of IBM Credit’s Date of Note. This discount is referred to as the High
Turnover Option (“HTO”).

         Each PRO Advance shall accrue a finance charge during the period from
the date such advance is made of maturity at the per annum rate specified in
Exhibit A as the “FPP PRO Financing Charge”. From and after maturity, the
delinquent portion of a PRO Advance shall accrue a Delinquency Fee in accordance
with Paragraph 2.8 hereof.

4.3   Working Capital Option.

         Provided that Customers have adequate Available Credit and provided
that no Event of Default has occurred under the Agreement, pursuant to the
Working Capital Option (“WCO”), Customers may request IBM Credit to provide cash
advances (“WCO Advances”). Customers shall provide IBM Credit with a written
request (“WCO Advance Request”) for a period (“WCO Term”) up to the maximum
approved term set forth in Exhibit A (“Maximum WCO Term”).

         The WCO Advance Request must state the WCO Advance amount requested.
Each WCO Advance Request is subject to IBM Credit’s approval and shall not
exceed the Maximum WCO Term. IBM CREDIT MAY, IN ITS SOLE DISCRETION, PROVIDE
SUCH WCO ADVANCE.

         If a WCO Advance Request is approved by IBM Credit, the WCO Term shall
commence on the date that the WCO Advance is made and shall end on the last day
of the approved WCO Term.

         At the conclusion of the WCO Term applicable to the WCO Advance, the
outstanding WCO Advance will be automatically renewed for another period equal
to the Maximum WCO Term unless IBM

Page 7 of 19

Credit informs Customers, in writing, at least thirty (30) days prior to the
conclusion of the current WCO Term that such WCO Advance will not be renewed. If
the outstanding WCO Advance is not renewed by IBM Credit, Customers agree to
repay the outstanding WCO Advance to IBM Credit no later than the last day of
the current WCO Term.

the date such advance is made to maturity at the per annum rate specified in
Exhibit A as the “FPP WCO Financing Charge”. From and after maturity, the
delinquent portion of a WCO Advance shall accrue a Delinquency Fee in accordance
with Paragraph 2.8 hereof.

         (a)  Customers shall establish and maintain a lockbox (“Lockbox”) at
the address set forth in Exhibit A with the financial institution listed in

form and substance satisfactory to IBM Credit. Customers shall also establish
and maintain a deposit account which shall contain only proceeds of Customers’
Accounts (“Special Account”) with Bank. Customers shall enter into a control
agreement with Bank and IBM Credit in form and substance satisfactory to IBM
Credit pursuant to which, among other things, Bank shall agree that its security

and that upon notice from IBM Credit, disbursements from the Lockbox or the
Special Account shall be made only as IBM Credit shall direct, without further
consent by Customers.

         (b)  Customers shall direct all Account Debtors to send all payments to
Customers’ lockbox. In addition, Customers shall have such instruction printed

agree that they shall not deposit or permit any deposits of funds other than
remittances paid in respect of the Accounts into the Special Account or permit
any commingling of funds with such remittances in the Lockbox or Special
Account.

         (c)  Without limiting the Customers’ foregoing obligations, if, at any
time, any Customer receives a remittance directly from an Account Debtor, then
such Customer shall make entries on its books and records in a manner that shall
reasonably identify such remittances and shall keep a separate account on its
record books of all remittances so received and deposit the same into Special
Account. Until so deposited into the Special Account, Customers shall keep all
remittances received in respect of Accounts separate from Customers’ other
property so that they are capable of identification as the proceeds of Accounts
in which IBM Credit has a security interest.

Section 9.0 Power of Attorney.

         Each Customer hereby irrevocably appoints IBM Credit (and any person
designated by it) as its true and lawful attorney-in-fact with full power, as it
pertains to the loan, at any time, in the sole discretion of IBM Credit, to:

applicable Customer’s rights and remedies with respect to the collection of any

to IBM Credit for application to the Obligations, or as otherwise directed by
IBM Credit.

         IBM Credit shall have no obligation to preserve rights to Accounts
against others and Customers hereby waive and release IBM Credit from any and
all claims and causes of action which Customers may now or hereafter have for
any loss or damage to Customers claimed by Customers to be caused by, or arising
from, IBM Credit’s actions and/or omissions relating to any Account Debtors,
including but not limited to:

         (a)  any failure of IBM Credit to protect, enforce or collect, in whole
or in any part, an Account;
