Buyer will not --------------------- purchase Eligible Receivables that Seller offers to the extent that the aggregate purchase price paid by Buyer for Purchased Receivables would exceed Ten Million Dollars ($10,000,000). Each purchase of Purchased Receivables shall be evidenced by an Instrument of Transfer and Assignment in substantially the form of Exhibit "A" attached hereto (the "Assignment"). ----------- ---------- (b) Conditions Precedent. Buyer, assuming that it has accepted a -------------------- Request, shall not be obligated to purchase Eligible Receivables described in such Request unless on the Purchase Date therefor: (i) Buyer has received all of the Receivables Documentation for such Eligible Receivables and such other supporting documentation that Buyer has reasonably requested; (ii) Seller's representations, warranties and covenants herein are true and accurate in all material respects on such Purchase Date; 1 (iii) No Event of Repurchase exists on such Purchase Date with respect to which Seller has not repurchased, and paid the full purchase price therefor, the affected Purchased Receivables to the extent required to do so in accordance with Section 7; and (iv) No default or event of default exists under the Seller's credit facility with ABN AMRO Bank, Comerica Bank and Industrial Bank of Japan or any other agreement for indebtedness for borrowed money with respect to which the Seller is the borrower or lessee thereunder, and no default or event of default would be caused under any of the foregoing agreements as a result of the purchase of the Eligible Receivables on such Purchase Date. (c) Purchase Price. The purchase price for Purchased Receivables (the -------------- "Purchase Price") purchased on a Purchase Date shall be ninety-six and sixty- -------------- six-one hundredths percent (96.66%) of the aggregate Net Invoice Amount of such Purchased Receivables (the "Aggregate Net Invoice Amount"). Buyer shall pay ---------------------------- the Purchase Price, denominated in U.S. dollars, to Seller in immediately available funds on the Purchase Date. (d) No Recourse. Except as otherwise provided in Section 7, each ----------- purchase of the Purchased Receivables is made without recourse to Seller and Seller shall have no liability to Buyer for any Eligible Customer's failure to pay any of its Purchased Receivables when it is due and payable under the terms of the applicable Receivables Documentation. (e) Collection Expenses Account. On the initial Purchase Date, Buyer --------------------------- shall establish an interest-bearing account (the "Collection Expenses Account") --------------------------- into which it shall deposit funds equal to one half of one percent (.5%) of the Net Invoice Amount of the Purchased Receivables acquired on such Purchase Date. On each subsequent Purchase Date, Buyer shall deposit into the Collection Expenses Account funds equal to one half of one percent (.5%) of the Net Invoice Amount of the Purchased Receivables acquired on such Purchase Date.

On the date that no further purchase transactions are authorized hereunder Seller, as compensation for the collection agent services performed hereunder, shall be entitled to all funds remaining in the Collection Expenses Account. (f) Rebate. Upon Buyer's receipt of all payments due with respect to ------ the Purchased Receivables purchased on a Purchase Date, whether through payments made by or on behalf of the Approved Customers and/or payments made under the Insurance Policy and payments made by Seller hereunder, Buyer and Seller shall determine the Average Collection Days for such Purchased Receivables. If the Average Collection Days is less than one hundred twenty (120) days (the "Projected Collection Days"), then Buyer shall pay to Seller the amount equal to - -------------------------- the result obtained by multiplying 0.02111% times the Net Invoice Amount of the subject Purchased Receivables times the difference between the Projected Collection Days less the Average Collection Days. 2.
