         product of:

                       ((2.0 * ED) + ((DS - ED) * DS / ED)) * DP

         Where:

<PAGE>

         ED  =  the average of the Dilution Ratios during the preceding twelve

         aggregate amount of all Receivables which arose during such Monthly
         Period and (ii) DSO divided by 30, and the denominator of which is the
         Net Receivables Balance as of the last day of such Monthly Period; and

         DSO  =  the number of calendar days equal to the product of (i) 91 and
         (ii) a fraction the numerator of which is the Net Receivables Balance
         as of the last day of such Monthly Period, and the denominator of which
         is the aggregate amount of all Receivables which arose during the
         preceding three consecutive Monthly Periods ending on the last day of
         the Monthly Period for which such Dilution Reserve Percentage is
         established.

         (ii) The defined terms "Dilution Spike" and "Expected Dilution" are
         hereby deleted from Section 1.01 of the Receivables Purchase Agreement.

         SECTION 2. Addition of New Section 2.06A to the Receivables Purchase

following new Section 2.06A immediately after Section 2.06 therein:

         Section 2.06A. Pooled Funding of Net Investment. Notwithstanding
         anything to the contrary contained in this Agreement, if the Buyer
         funds all or a portion of the Net Investment through the issuance of
         Commercial Paper, it may (in its sole discretion) elect to do so
         through the issuance of Commercial Paper tranches the proceeds of which
         are not used exclusively for the purpose of funding the Net Investment
         hereunder (a "Pooled Funding"). To the extent the Buyer (in the
         exercise of its sole discretion) funds all or a portion of the Net
         Investment on a Pooled Funding basis, (i) the Seller shall have no
         right to request Tranche Periods, (ii) the Tranche Rate for the portion
         of the Net Investment funded on a Pooled Funding basis shall be, for
         each day, the rate equivalent of the weighted average of the rates
         payable on all Commercial Paper of the Buyer issued on a Pooled Funding
         basis on such day, converted (as necessary) to an annual yield
         equivalent rate on the basis of a 360-day year, which rates shall
         include any dealer's discount or fees and any other fees attributable
         thereto, (iii) the portion of the Net Investment funded on a Pooled
         Funding basis shall be deemed to be allocated to a Tranche with a
         Tranche Period maturing on the last calendar day of each calendar
         month, (iv) if the report delivered by the Administrative Agent to the
         Seller pursuant to Section 2.07 includes an estimate with respect to a
         Tranche funded on a Pooled Funding basis, the Administrative Agent
         shall deliver a revised report to the Seller on or before the last
         calendar day of the applicable calendar month and the Seller shall pay
         the Discount shown thereon on the last calendar

                                        2

<PAGE>

         day of such calendar month, and (v) the other terms and provisions of
         this Agreement shall be construed and applied in a manner consistent
         with this Section 2.06A (whether or not such terms and provisions are
         referenced with specificity in this Section 2.06A) and all Pooled
         Funding shall be administered by the Administrative Agent in accordance
         with its general policies and procedures applicable to Pooled Funding.

         SECTION 3. Receivables Purchase Agreement in Full Force and Effect, as
Amended. Except as specifically stated herein, all of the terms and conditions
of the Receivables Purchase Agreement shall remain in full force and effect. All
references to the Receivables Purchase Agreement in any Purchase Document or any
other document or instrument shall be deemed to mean the Receivables Purchase
Agreement, as amended by this Amendment. This Amendment shall not constitute a
novation of the Receivables Purchase Agreement, but shall constitute an
amendment thereto. The parties hereto agree to be bound by the terms and
obligations of the Receivables Purchase Agreement, as amended by this Amendment,
as though the terms and obligations of the Receivables Purchase Agreement were
set forth herein.

         SECTION 4. Effectiveness. This Amendment shall become effective as of
the date hereof, upon receipt by the Administrative Agent of an executed
counterpart of this Amendment from each party hereto (including the
acknowledgement and consent of JPMorgan Chase Bank, as Agent for the APA
Purchasers).

         SECTION 5. Counterparts. This Amendment may be executed in any number
of counterparts and by separate parties hereto on separate counterparts
(including by way of facsimile transmission), each of which when executed shall
be deemed an original, but all such counterparts taken together shall constitute
one and the same instrument.

         SECTION 6. Governing Law. THIS AMENDMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
