The notice of redemption will specify, among other items, the Redemption Price and the principal amount of the Underwritten Securities held by such person to be redeemed. DEFINITIONS. As used herein, - ----------- "Make-Whole Amount" means, in connection with any optional redemption or accelerated payment of any Underwritten Securities, 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 if such redemption or accelerated payment had not been made, determined by discounting, on a semiannual 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 Underwritten Securities being redeemed or paid. "Reinvestment Rate" means .25% (one-fourth of one percent) plus the arithmetic mean of the yields under the respective heading "Week Ending" published in the most recent Statistical Release under the caption "Treasury Constant Maturities" for the maturity (rounded to the nearest month) corresponding to the remaining life -4- to maturity, 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 the 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. "Statistical Release" means the statistical release designated "H.15(519)" or any successor publication which is published weekly by the Federal Reserve System and which establishes yields on actively traded United States government securities adjusted to constant maturities, or, if such statistical release is not published at the time of any determination under the Indenture, then such other reasonably comparable index which shall be designated by ERP. "Subsidiary" means a corporation, a limited liability company or a partnership a majority of the outstanding voting stock, limited liability company interests or partnership interests, as the case may be, of which is owned, directly or indirectly, by ERP or by one or more other Subsidiaries of ERP. For the purposes of this definition, "voting stock" means stock having voting power for the election of directors, managing members or trustees, whether at all times or only so long as no senior class of stock has such voting power by reason of any contingency. "Total Unencumbered Assets" means the sum of (i) those Undepreciated Real Estate Assets not subject to an encumbrance and (ii) all other assets of the Operating Partnership and its Subsidiaries not subject to an encumbrance determined in accordance with GAAP (but excluding accounts receivable and intangibles). "Undepreciated Real Estate Assets" as of any date means the cost (original cost plus capital improvements) of real estate assets of ERP and its Subsidiaries on such date, before depreciation and amortization determined on a consolidated basis in accordance with GAAP.
