The bonds shall bear interest at a rate or rates not exceeding 7 percent per annum, payable semiannually, except that the first interest payable on the bonds or any series thereof may be for any period not exceeding one year as determined by the board. In the resolution or resolutions providing for the issuance of the bonds, the board may also provide for call and redemption of the bonds prior to maturity at the times and prices and upon any other terms it may specify, but no bond shall be subject to call or redemption prior to maturity unless it contains a recital to that effect or unless a statement to that effect is printed thereon. The denomination or denominations of the bonds shall be stated in the resolution providing for their issuance, but shall not be less than one thousand dollars ($1,000). The principal of and interest on the bonds shall be payable in lawful money of the United States at the office of the treasurer of the district or at any other place or places that may be designated, or at either place or places at the option of the holders of the bonds. The bonds, or series thereof, shall be dated and numbered consecutively and shall be signed by the chairperson of the board and the treasurer, countersigned by the secretary and the official seal of the district attached. The interest coupons of the bonds shall be signed by the treasurer. All signatures, countersignatures, and seal may be printed, lithographed, or mechanically reproduced, except that one of the signatures or countersignatures on the bonds shall be manually affixed. If any officer whose signature or countersignature appears on bonds or coupons ceases to be an officer before the delivery of the bonds, his or her signature is as effective as if he or she had remained in office.
