SECTION 1. The Thirty-second Series of Bonds to be executed, authenticated and delivered under and secured by the Indenture shall be Bonds of MTN Series C, designated as "First Mortgage Bonds, Secured Medium-Term Notes, Series C" of the Company. The Bonds of MTN Series C shall be executed, authenticated and delivered in accordance with the provisions of, and shall in all respects be subject to, all of the terms, conditions and covenants of the Original Indenture, except insofar as the terms and provisions of the Original Indenture have been or are amended or modified by said First through Thirty-fourth Supplemental Indentures or by this Thirty-fifth Supplemental Indenture. Bonds of MTN Series C shall be issued from time to time in an aggregate principal amount not to exceed $200,000,000, be issued as registered Bonds without coupons in the denominations of $1,000 or in any multiple thereof; each Bond of MTN Series C shall mature on such date not less than nine months nor more than forty years from date of issue, shall bear interest at such rate or rates (which may be either fixed or variable) and have such other terms and provisions not inconsistent with the Indenture as the Board of Directors may determine in accordance with a resolution filed with the Corporate Trustee and a written order referring to this Thirty-fifth Supplemental Indenture; the principal of and interest on each said Bond to be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York and, at the option of the Company, interest on each said Bond may also be payable at the office of the Company in Boise, Idaho, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts. Interest on Bonds of MTN Series C which bear interest at a fixed rate shall be payable semiannually on April 1 and October 1 of each year or on such other dates as set forth in a resolution filed with the Corporate Trustee referring to this Thirty-fifth Supplemental Indenture and at maturity or upon earlier redemption (each an interest payment date). Interest on Bonds of MTN Series C which bear interest at a variable rate shall be payable on the dates (each an interest payment date) set forth in a resolution filed with the Corporate Trustee referring to this Thirty-fifth Supplemental Indenture. Notwithstanding the foregoing, so long as there is no existing default in the payment of interest on the Bonds of MTN Series C, all Bonds of MTN Series C authenticated by the Corporate Trustee after the Record Date hereinafter specified for any interest payment date, and prior to such interest payment date (unless the date of first authentication of Bonds of such designated -6- interest rate and maturity is after such Record Date), shall be dated the date of authentication, but shall bear interest from such interest payment date, and the person in whose name any Bond of MTN Series C is registered at the close of business on any Record Date with respect to any interest payment date shall be entitled to receive the interest payable on such interest payment date, notwithstanding the cancellation of such Bond of MTN Series C, upon any transfer or exchange thereof subsequent to the Record Date and on or prior to such interest payment date. If the date of first authentication of the Bonds of MTN Series C of a designated interest rate and maturity is after such Record Date and prior to the corresponding interest payment date, such Bonds shall bear interest from the Original Interest Accrual Date but payment of interest shall commence on the second interest payment date succeeding the Original Interest Accrual Date. "Record Date" for Bonds of MTN Series C which bear interest at a fixed rate shall mean March 15 for interest payable April 1 and September 15 for interest payable October 1; for Bonds of MTN Series C which bear interest at a fixed rate that is payable on other dates, shall mean the last day of the calendar month preceding such interest payment date if such interest payment date is the fifteenth day of a calendar month and shall mean the fifteenth day of the calendar month preceding such interest payment date if such interest payment date is the first day of a calender month, as determined by the Board of Directors and set forth in a resolution filed with the Corporate Trustee referring to this Thirty-fifth Supplemental Indenture; and for Bonds of MTN Series C which bear interest at a variable rate, the date 15 calendar days prior to any interest payment date, provided that, interest payable on the maturity date will be payable to the person to whom the principal thereof shall be payable. "Original Interest Accrual Date" with respect to Bonds of MTN Series C of a designated interest rate and maturity shall mean the date of first authentication of Bonds of such designated interest rate and maturity unless a written order filed with the Corporate Trustee on or before such date shall specify another date from which interest shall accrue, in which case "Original Interest Accrual Date" shall mean such other date specified in the written order for Bonds of such designated interest rate and maturity. The Bonds of MTN Series C, in definitive form, shall be, at the option of the Company, fully engraved or shall be lithographed or printed on steel engraved borders or shall be partially lithographed or printed and partially engraved on steel borders or shall be printed on safety paper or shall be typewritten. The holders of the Bonds of MTN Series C consent that the Company may, but shall not be obligated to, fix a record date for the purpose of determining the holders of Bonds of MTN Series C entitled to consent to any amendment, supplement or waiver. If a record date is fixed, those persons who are holders at such record date (or their duly designated proxies), and only those persons, shall be entitled to consent to such amendment, supplement or waiver or to revoke any consent previously given, whether or not such persons continue to be holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date. The Bonds of MTN Series C may be redeemable at the option of the Company (including without limitation redemptions by the application of cash deposited with the Corporate Trustee pursuant to Section 39 of the Indenture) in whole at any time, or in part from time to time, -7- prior to maturity, as provided in Section 52 of the Indenture, upon giving notice of such redemption by first class mail, postage prepaid, by or on behalf of the Company at least thirty (30) days prior to the date fixed for redemption as the Board of Directors may determine in accordance with a resolution filed with the Corporate Trustee and a written order referring to this Thirty-fifth Supplemental Indenture SECTION 2. At the option of the registered holder, any Bonds of MTN Series C, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, together with a written instrument of transfer (if so required by the Company or by the Trustees) in form approved by the Company duly executed by the registered holder or by his duly authorized attorney, shall be exchangeable for a like aggregate principal amount and maturity of Bonds of MTN Series C of other authorized denominations. Bonds of MTN Series C may bear such legends as may be necessary to comply with any law or with any rules or regulations made pursuant thereto or with the rules or regulations of any stock exchange or to conform to usage with respect thereto. Bonds of MTN Series C shall be transferable at the office or agency of the Company in the Borough of Manhattan, The City of New York. Notwithstanding the foregoing provisions of this Section 2, the Company shall not be required to make any transfers or exchanges of Bonds of MTN Series C for a period of fifteen (15) days next preceding any mailing of notice of redemption, and the Company shall not be required to make transfers or exchanges of the principal amount of any Bonds of MTN Series C so called or selected for redemption. SECTION 3. The Bonds of MTN Series C shall be substantially of the tenor and purport recited in the Original Indenture, and the form thereof shall be as established by resolution of the Board of Directors or the Executive Committee of the Board of Directors of the Company, which resolution may provide that any provisions of such form of Bond may appear on the reverse of such form.
