Bonds authorized by resolution of the authority may be issued in one or more series and shall bear such date or dates, mature at such time or times, bear interest at such rate or rates, provided that the bonds of any issue shall not bear a greater overall maximum interest rate to maturity than that allowed in Section 75-17-103, be in such denomination or denominations, be in such form, either coupon or registered, carry such conversion or registration privileges, have such rank or priority, be executed in such manner, be payable in such medium of payment, at such place or places, and be subject to such terms of redemption (with or without premium) as such resolution, its trust indenture or mortgage may provide. No bond shall bear more than one (1) rate of interest; each bond shall bear interest from its date to its stated maturity date at the interest rate specified in the bid; all bonds of the same maturity shall bear the same rate of interest from date to maturity; all interest accruing on such bonds so issued shall be payable semiannually or annually, except that the first interest coupon attached to any such bond may be for any period not exceeding one (1) year.

No interest payment shall be evidenced by more than one (1) coupon and neither cancelled nor supplemental coupons shall be permitted; the lowest interest rate specified for any bonds issued shall not be less than seventy percent (70%) of the highest interest rate specified for the same bond issue.

Each interest rate specified in any bid must be in multiples of one-eighth of one percent (⅛ of 1%) or in multiples of one-tenth of one percent (1/1 of 1%). The denomination, form and place or places of payment of such bonds shall be fixed in the resolution or ordinance of the governing authorities issuing such bonds. Such bonds shall be executed by the manual or facsimile signature of the chairman and secretary of such authority, with the seal of the authority affixed thereto. At least one (1) signature on each bond shall be a manual signature, as specified in the resolution. The coupons may bear only the facsimile signatures of such chairman and secretary. No bonds shall be issued and sold under the provisions of this chapter for less than par and accrued interest.

The bonds may be sold at not less than par at public sale held after notice published once at least five (5) days prior to such sale in a newspaper having a general circulation in the area of operation and in a financial newspaper published in the City of Jackson, Mississippi, or in the City of New York, New York. Such bonds may be sold at not less than par to the federal government at private sale without any public advertisement.

In case any of the commissioners or officers of the authority whose signatures appear on any bonds or coupons shall cease to be such commissioners or officers before the delivery of such bonds, such signatures shall, nevertheless, be valid and sufficient for all purposes, the same as if such commissioners or officers had remained in office until such delivery. Any provision of any law to the contrary notwithstanding, any bonds issued pursuant to this chapter shall be fully negotiable.

The determination of the authority, in the resolution authorizing the bonds, as to the classification of the railroad properties and facilities for which such bonds are authorized and as to the maximum period of usefulness shall be conclusive in any action or proceeding involving the validity of such bonds.
