Prior to the leasing of any project, the governing body must determine and find the following: the amount necessary in each year to pay the principal of and the interest on the bonds proposed to be issued to finance such project; the amount necessary to be paid each year into any reserve funds, which amounts may include deposits in escrow or reserve amounts as advance sums for the payment of insurance, which the governing body may deem it advisable to establish in connection with the retirement of the proposed bonds and the maintenance of the project; and, unless the terms under which the project is to be leased provide that the lessee shall maintain the project and carry all proper insurance with respect thereto, the estimated cost of maintaining the project in good repair and keeping it properly insured. The determinations and findings of the governing body required to be made in the preceding sentence shall be set forth in the proceedings under which the proposed bonds are to be issued; and prior to the issuance of such bonds, the municipality shall lease the project to a lessee under an agreement conditioned upon completion of the project and providing for payment to the municipality of such rentals as, upon the basis of such determinations and findings, will be sufficient (a) to pay the principal of and interest on the bonds issued to finance the project, (b) to build up and maintain any reserve deemed by the governing body to be advisable in connection therewith, and (c) unless the agreement of lease obligated the lessee to pay for the maintenance and insurance of the project, to pay the cost of maintaining the project in good repair and keeping it properly insured. Such lease shall be made upon such other terms and conditions and for the time which may be determined by the municipality and may contain provisions authorizing the purchase of the entire project or any portion thereof by the industry or its assignee after all bonds (if any) issued thereunder have been paid in full, for such consideration and upon such terms and conditions as the municipality may determine.
