Iowa Code § 262A.7
Upon the determination by the state board of regents to undertake and carry out any project or to refund outstanding bonds, said board shall adopt a resolution describing generally the contemplated project and setting forth the estimated cost thereof, or describing the obligations to be refunded, fixing the amount of bonds to be issued, the maturity or maturities, the interest rate or rates and all details in respect thereof. Such resolution shall contain such covenants as may be determined by the board as to the issuance of additional bonds that may thereafter be issued payable from the student fees and charges and institutional income received by the particular institution, the amendment or modification of the resolution authorizing the issuance of any bonds, the manner, terms, and conditions and the amount or percentage of assenting bonds necessary to effectuate such amendment or modification, and such other covenants as may be deemed necessary or desirable. In the discretion of the board any bonds issued under the terms of this chapter may be secured by a trust indenture by and between the board and a corporate trustee, which may be any trust company or bank having the powers of a trust company within or without the boundaries of the state of Iowa, but no such trust indenture shall convey or mortgage the buildings and facilities or any part thereof. The provisions of this chapter and of any resolution or other proceedings authorizing the issuance of bonds and providing for the establishment and maintenance of adequate student fees and charges and the application of the proceeds thereof, together with institutional income, shall constitute a contract with the holders of such bonds.
