Before issuing any bond or bonds pursuant to this chapter, the regents shall by resolution declare the purpose for which the proceeds of the bonds proposed to be issued shall be expended and shall specify the maximum amount of bonds to be issued or sold for such purpose. Bonds shall not be issued or sold for such purpose in an amount exceeding the maximum specified in such resolution except with the consent of bondholders, pursuant to amendment or modification of an indenture, as provided in Sections 92528 and 92529. Nothing in this section shall be construed to prevent the regents from amending any such resolution prior to the issuance of bonds authorized thereby to increase or decrease the maximum amount of bonds to be issued or sold. The issuance of bonds for one or more projects may be included in a single resolution of authorization.
