The term "Record Date" as used with respect to any Interest Payment Date or Installment Payment Date (except a date for payment of Defaulted Interest or Defaulted Installment) shall mean, with respect to the 1995 Series Bonds, the December 15 or June 15 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date or Installment Payment Date, as the case may be. "Defaulted Installment" shall mean any unpaid installment payment of principal of a 1995 Series Bond in respect of which the Owner Trust shall default in the payment when due on an Installment Payment Date. All references in the Indenture to the principal amount of Bonds shall, when used with respect to the 1995 Series Bonds, mean the unpaid principal amount thereof, except that, for purposes of Section 2.06, and 2.07 and 6.08 of the Indenture, principal amount shall, when used with respect to the 1995 Series Bonds, refer to Original Principal Amount.

The 1995 Series Bonds shall be subject to redemption in whole but not in part, at 100% of the unpaid principal amount thereof, together with interest accrued to the Redemption Date, upon the receipt of payment of the applicable purchase price or Termination Value -4- 5 resulting from a termination of the Lease pursuant to Section 7 thereof. (b) Mandatory Redemption - Event of Loss. The 1995 Series Bonds shall be subject to redemption, at 100% of the unpaid principal amount thereof, together with interest accrued to the Redemption Date upon the receipt of the applicable payment of Casualty Value resulting from an Event of Loss under the Lease (unless, in connection with an Event of Loss described in clause (e) of the definition thereof, TU Electric assumes the 1995 -5- 6 Series Bonds then Outstanding pursuant to Section 2.16 of the Indenture), in the principal amount equal to the product of (i) the aggregate unpaid principal amount of 1995 Series Bonds then Outstanding and (ii) a fraction the numerator of which is the Purchase Price of the Facility to which such Event of Loss pertains and the denominator of which is the aggregate Purchase Price of the Facilities then subject to the Lien of the Indenture. The aggregate amount payable upon a partial redemption pursuant to this subsection 1.02(b) shall be allocated among the Holders of 1995 Series Bonds pro rata, in proportion, as nearly as practicable, to the respective unpaid principal amount of 1995 Series Bonds held by such Holders, and upon payment of the applicable redemption price to the Holders in accordance with the Indenture, the unpaid principal amount of each 1995 Series Bond recorded on the Bond Register maintained by the Indenture Trustees shall be controlling. (c) Installment Payments. On each Installment Payment Date, the Holder of a 1995 Series Bond will receive a payment of principal equal to the Installment Payment Percentage for such Installment Payment Date multiplied by the Original Principal Amount of such 1995 Series Bond.
