The governing board of the issuing unit shall determine the form and manner of execution of the bonds, including any interest coupons to be attached thereto. The board may also provide for the authentication of the bonds by a trustee or fiscal agent. The board may authorize the use of facsimile signatures and seals on the bonds and coupons, if any, but at least one manual signature (which may be the signature of the representative of the Commission to the Commission’s certificate) must appear on each bond that is represented by an instrument. Delivery of bonds executed in accordance with the board’s determination shall be valid notwithstanding any change in officers or in the seal of the issuing unit occurring after the original execution of the bonds.

Before definitive bonds are prepared, the unit may issue interim receipts or temporary bonds, with or without coupons, exchangeable for definitive bonds when they have been executed and are available for delivery.
