AMENDMENTS

Section 2.1. Definition of Make-Whole Amount. The definition of “Make-Whole Amount” set forth in Section 1.1 of the Indenture is hereby amended and restated in its entirety solely with respect to the Affected Securities as follows:

“Make-Whole Amount” means, in connection with any optional redemption or accelerated payment of any Security, the excess, if any, of (i) the aggregate present value as of the date of such redemption or accelerated payment of each dollar of principal being redeemed or paid and the amount of interest (exclusive of interest accrued to the date of redemption or accelerated payment) that would have been payable in respect of such dollar to the applicable Par Call Date if such redemption or accelerated payment had not been made, determined by discounting, on a semi-annual basis, such principal and interest at the Reinvestment Rate (determined on the third Business Day preceding the date such notice of Redemption is given or declaration of acceleration is made) from the respective dates on which such principal and interest would have been payable if such redemption or accelerated payment had not been made, over (ii) the aggregate principal amount of the Securities being redeemed or paid; provided, however, that if the Issuer redeems any Security on or after the applicable Par Call Date, no Make-Whole Amount will be due and payable.”

Section 2.2. Definition of Par Call Date. Section 1.1 of the Indenture is hereby amended solely with respect to the Affected Securities to add the following defined term:

“Par Call Date” means, with respect to any Security, the date established by Board Resolution (or in the absence of such a Board Resolution, the Stated Maturity of such Security).

Section 2.3. Definition of Reinvestment Rate. The definition of “Reinvestment Rate” set forth in Section 1.1 of the Indenture is hereby amended and restated in its entirety solely with respect to the Affected Securities as follows:

“Reinvestment Rate” means the percentage established by Board Resolution (or, in the absence of such a Board Resolution, 0.25% (twenty-five one hundredths of one percent)) plus the arithmetic mean of the yields under the respective heading “Week Ending” published in the Statistical Release under the caption “Treasury Constant Maturities” for the maturity (rounded to the nearest month) corresponding to the remaining life to maturity (assuming that the Securities matured on the Par Call Date, the “remaining life”) of the Securities of the relevant series, as of the payment date of the principal being redeemed or paid. If no maturity exactly corresponds to such maturity, yields for the two published maturities most closely corresponding to such maturity shall be calculated pursuant to the immediately preceding sentence and the Reinvestment Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding in each of such relevant periods to the nearest month. For purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the Make-Whole Amount shall be used.

Section 2.4. Waiver of the Corporate Seal. For the purposes of the Affected Securities, it is agreed that the corporate seal of the general partner referred to in Section 3.3 of the Indenture shall not be required to be affixed to the Affected Securities for the Affected Securities to be duly and validly issued pursuant to the Indenture.
