                  the case of any Committed Lender, exceed (after giving effect
                  to all Loans of such Committed Lender and any Conduit Lender
                  designated by such Committed Lender repaid concurrently with
                  the making of such Loans) its Available Commitment; (ii)

                  Each Borrowing shall be in an aggregate principal amount of
                  $5,000,000, in the case of the first Borrowing hereunder, or
                  $1,000,000, in the case of subsequent Borrowings, or, in each
                  case, any larger amount (except that any such Borrowing may be
                  in the aggregate amount of the unused Commitments) and shall
                  be made from the several Committed Lenders ratably in
                  proportion to their respective Commitments. The Lenders have
                  no obligation to make any Loan hereunder except as expressly
                  set forth in this Agreement. Within the foregoing limits, the
                  Borrower may borrow under this Section 2.01, repay, or, to the
                  extent permitted by Section 2.07, prepay, Loans and reborrow

                  on any Funding Date, the Agent may in its sole discretion
                  grant the Borrower a temporary waiver for a specified period
                  of time to perform its obligations under clauses (a) or (b) or
                  the last sentence of clause (c) of Section 2.02 and to fulfill
                  the conditions set forth in Section 4.02 (other than clauses

                  Committed Lenders (or from their related Conduit Lenders)
                  ratably in proportion to the respective Commitments of such
                  Committed Lenders, or which requires payments of principal and
                  interest on the Loans to be made and allocated, or Loans to be
                  continued or converted, based on Commitment Percentages rather
                  than outstanding principal amounts:

                  (1)      If, as a result of any increase in a Committed
                           Lender's Commitment, its Commitment Percentage is
                           greater than the percentage which the Loans of such
                           Committed Lender and its related Conduit Lenders
                           constitutes of the aggregate outstanding Loans of all
                           Lenders, then any further Borrowing will be made from
                           such Committed Lender and its related Conduit Lenders
                           on a non-pro-rata basis until their outstanding Loans
                           constitute

                                      -4-


                           the same percentage of all the outstanding Loans as
                           such Committed Lender's Commitment Percentage,

                  (2)      payments of principal and interest on the Loans will
                           be made to the Lenders according to the respective
                           outstanding principal amounts of such Loans, and

                  (3)      outstanding Loans will be continued and converted
                           according to their outstanding principal amounts
                           rather than the Committed Percentages of the
                           applicable Lenders."

13.      Section 2.01(ii)(B) of the Agreement is hereby amended by inserting the
words "then in effect" immediately after the words "Advance Rate" therein.

14.      Section 2.05(a) of the Agreement is hereby amended in its entirety to
read as follows:

                           "(a) Rate of Interest. (i) Each Loan shall bear
                  interest on the outstanding principal amount thereof, for each
                  day during each Interest Period applicable thereto, at a rate
                  per annum equal to the Applicable Rate for such day, or if any
                  Conduit Lender shall so designate (in accordance with the
                  definition of CP Rate) for any Loan funded and maintained by
                  such Conduit Lender through the issuance of commercial paper,
                  the CP Rate for such day; provided that any change to the
                  interest rate shall not take effect until the next succeeding
                  Interest Period after such designation. Such interest shall be
                  payable in arrears on each Settlement Date and on the
                  Termination Date.

                           (ii) At any time during which an Event of Default has
                  occurred and is continuing, each Loan shall bear additional
                  interest (in addition to the interest payable pursuant to
                  Section 2.05(a)(i)) on the outstanding principal amount
                  thereof, for each day during each Interest Period applicable
                  thereto, at a rate per annum equal to the Default Margin and
                  such accrued additional interest shall be aggregated on the
                  last day of such Interest Period (all such aggregated
                  additional interest, the "Aggregated Default Interest"). Such
                  Aggregated Default Interest shall bear interest on the
                  outstanding amount thereof, for each day during each Interest
                  Period applicable thereto, at a rate per annum equal to the
                  Aggregated Default Interest Rate and such accrued interest
                  shall be aggregated on the last day of such Interest Period
                  with the Aggregated Default Interest and shall be deemed
                  "Aggregated Default Interest" upon such aggregation.
                  Aggregated Default Interest and the interest thereon shall be
                  payable in arrears on the date on which the aggregate
                  principal amount of the Loans have been paid in full pursuant
                  to the terms of this Agreement."

                  such Lender) extend any such payment date on terms
                  satisfactory to such Lenders (in their sole discretion);
                  provided that, any such extension shall not extend any such
                  payment beyond the Termination Date. For the avoidance of
                  doubt, principal amounts of the Loans prepaid after the
                  Revolving Termination Date in accordance with Section 2.07(a)
