For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

“Called Principal” shall mean, with respect to any Series 2008-A Note, the principal of such Series 2008-A Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

“Reinvestment Yield” shall mean, with respect to the Called Principal of any Series 2008-A Note, .50% over the yield to maturity implied by (a) the yields reported, as of 10:00 a.m. (New York, New York time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated a “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets

In the case of each determination under clause (a) or (b), as the case may be, of the preceding paragraph, such implied yield will be determined, if necessary, by (1) converting U.S. Treasury bill quotations to bond-equivalent yields in accordance with accepted financial practice and (2) interpolating linearly between (i) the applicable U.S. Treasury Security with the maturity closest to and greater than such Remaining Average Life and (ii) the applicable U.S. Treasury Security with the maturity closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of such Series 2008-A Note.

“Remaining Average Life” shall mean, with respect to the Called Principal of any Series 2008-A Note, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (a) such Called Principal into (b) the sum of the products obtained by multiplying (1) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (2) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” shall mean, with respect to the Called Principal of any Series 2008-A Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of such Series 2008-A Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or Section 12.1.

“Settlement Date” shall mean, with respect to the Called Principal of any Series 2008-A Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.
