The authority and the executive head of any agency, board, commission, public corporation, bureau or department of the State of Alabama, or the successor in office and duties of such executive head, are hereby authorized to enter into a lease or leases for the use and occupancy of offices and storage space in the public office buildings or buildings constructed, renovated, reconstructed, improved, altered, added to or equipped and owned by the authority under the provisions of this article. Such executive heads are hereby separately authorized to enter into lease agreements for the use and occupancy of any space in the said buildings. The authority and the Director of Finance on behalf of the Finance Department are hereby authorized to enter into a lease or leases for the use and occupancy of any or all of said buildings. In such event, the Finance Department may sublease space in said buildings upon such terms and conditions as may be determined by the Director of Finance. Upon a determination by the authority that a lessee has failed or refused to pay the lease payment charged to it under its lease agreement with the authority and that said lease payments are at least 90 days in arrears, the authority may request that the Director of Finance direct the state Comptroller to issue a state warrant to the authority in the amount of the delinquent lease payments. If the Director of Finance finds that the lessee has funds appropriated, budgeted and allotted for such payments, he may direct the state Comptroller to issue a state warrant to the authority in the amount owed. The state Comptroller is authorized to pay to the authority the amount of the delinquent lease payments that he finds to be appropriated, budgeted and allotted for that purpose if sufficient funds are then available in the fund from which such payments are to be made.
