Amendment to Original Indenture. The first and second paragraphs of Section 7.01 of the Original Indenture are designated paragraphs "(a)" and "(b)", respectively. There is added to the Original Indenture the following provision: "(c) Pursuant to the Series 1986A Series Supplemental Indenture dated as of July 15, 1986 (the Series 1986A Supplement), the Company issued a series of Securities designated "Lease Obligation Bonds Series 1986A" (the Series A Bonds), of which, on June 1, 1994 two Stated Maturities of principal remain outstanding: July 15, 1996 and January 15, 2014. Paragraph (b) of Section 7.01 of the Original Indenture to the contrary notwithstanding, in the event that there shall have been any partial redemption of Series A Bonds of a particular Stated Maturity of principal (other than pursuant to the Sinking Fund), the Sinking Fund payments thereafter to be made with respect to such Series A Bonds shall be adjusted as follows. The Company shall first identify all related Pledged Lessor Notes (as defined in Article II of Series 1986A Supplement and identified in Schedule 2 thereto) having the same maturity as the Series A Bonds of such particular Stated Maturity of principal redeemed, if any, which are outstanding following such redemption; provided, however, that for purposes of this Section 7.01(c), any such Pledged Lessor Notes with a maturity subsequent to January 15, 2010 shall be deemed to have a maturity of January 15, 2014. Having identified all such outstanding Pledged Lessor Notes (the Outstanding Notes), the Company shall determine the dates on which the principal of such Outstanding Notes is to be amortized (the Scheduled Amortization Dates). The amount of the Sinking Fund payment scheduled to be made on each Sinking Fund Date subsequent to the date of such partial redemption shall then be adjusted to equal the aggregate principal amount of all Outstanding Notes scheduled to be amortized on the Scheduled Amortization Date corresponding to such Sinking Fund Date. All such adjustments in respect of Sinking Fund payments on a Sinking Fund Date shall be rounded to the nearest $1,000, and shall be subject to necessary further adjustment so that the total amount of such reduction is at least equal to the total principal amount of Series A Bonds redeemed pursuant to such partial redemption. Having made the calculations required by the preceding two sentences, the Company shall deliver to the Trustee a Company Request not later than 30 days following any partial redemption of Series A Bonds (other than pursuant to the Sinking Fund), setting forth (x) the schedules of principal amortization of all related Outstanding Notes having the same maturity as the Stated Maturity of principal of the Series A Bonds redeemed and (y) a revised schedule of Sinking Fund payments applicable to Series A Bonds having the same Stated Maturity of principal as the Series A Bonds redeemed. The Trustee may rely on such Company Request and shall have no duty with respect to the adjustments set forth therein other than to make them available for inspection by a Holder of Series A Bonds at the Corporate Trust Office upon reasonable notice." SECTION 1.02. Effectiveness. (a) The amendments to the Original Indenture specified in Section 1.01 shall become effective for all purposes of the Indenture, without necessity for further act by or notice to PNM, the Company or the Trustee, upon the execution and delivery of this 1994 Supplemental Indenture by the Trustee. (b) Upon the effectiveness of the amendments to the Original Indenture specified in Section 1.01, the Original Indenture shall, as provided in Section 11.05 thereof, be modified accordingly and such amendments shall form a part of the Indenture for all purposes and every Holder of 1986A Bonds shall be bound thereby.
