(1) All monies of the corporation, except as otherwise authorized or provided in this act, shall be paid to the commissioner of taxation and finance as agent of the corporation, who shall not commingle such monies with any other monies. Such monies shall be deposited in a separate bank account or accounts. The monies in such accounts shall be paid out on checks signed by the commissioner of taxation and finance on requisition of the chairman of the corporation or of such other officer or employee or officers or employees as the corporation shall authorize to make such requisition. All deposits of such monies shall, if required by the commissioner of taxation and finance or the corporation, be secured by obligations of the United States or of the state of a market value equal at all times to the amount of the deposit, and all banks and trust companies are authorized to give such security for such deposits. Notwithstanding the provisions of this section, the corporation shall have power to contract with the holders of any of its notes or bonds, as to the custody, collection, securing, investment, and payment of any monies of the corporation, of any monies held in trust or otherwise for the payment of notes or bonds, and to carry out such contract. Monies held in trust or otherwise for the payment of notes or bonds or in any way to secure notes or bonds and deposits of such monies may be secured in the same manner as monies of the corporation, and all banks and trust companies are authorized to give such security for such deposits.
