The issuance of bonds or bond anticipation notes issued under sections 13b-74 to 13b-77, inclusive, shall not directly or indirectly or contingently obligate the state or any political subdivision thereof to levy or to pledge any form of taxation whatever therefor, except for taxes included in the pledged revenues, or to make any additional appropriation for their payment. Such bonds and bond anticipation notes shall not constitute a charge, lien or encumbrance, legal or equitable, upon any property of the state or of any political subdivision thereof other than the pledged revenues or other receipts, funds or moneys pledged therefor as provided in sections 3-21a, 3-27a, 3-27f, 12-458 and 12-458d, subsection (c) of section 13a-80a, sections 13a-175p to 13a-175u, inclusive, subsection (f) of section 13b-42, sections 13b-59, 13b-61, 13b-69, 13b-71, 13b-74 to 13b-77, inclusive, and 13b-80, subsection (a) of section 13b-97, subsection (a) of section 14-12, except for subdivision (2) of said subsection (a), sections 14-15, 14-16a and 14-21c, subsection (a) of section 14-25a, section 14-28, subsection (b) of section 14-35, subsection (a) of section 14-41, section 14-41a, subsection (a) of section 14-44, sections 14-47, 14-48b, 14-49 and 14-50, subsection (a) of section 14-50a, sections 14-52 and 14-58, subsection (c) of section 14-66, subsection (e) of section 14-67, sections 14-67a, 14-67d, 14-67 l and 14-69, subsection (e) of section 14-73, subsection (c) of section 14-96q, sections 14-103a and 14-160, subsection (a) of section 14-164a, subsection (a) of section 14-192, sections 14-319, 14-320 and 14-381, subsection (b) of section 14-382 and section 15-14, and the substance of such limitation shall be plainly stated on the face of each such bond and bond anticipation note.

The State Bond Commission shall determine the form of the bonds, the manner of execution of the bonds, the denomination or denominations of the bonds and the manner of payment of principal and interest. Prior to the preparation of definitive bonds, the State Bond Commission may, under like restrictions, authorize the issuance of interim receipts or temporary bonds, exchangeable for definitive bonds when such bonds have been executed and are available for delivery. If any of the officers whose signatures appear on the bonds cease to be officers before the delivery of any such bonds, such signatures shall, nevertheless, be valid and sufficient for all purposes, the same as if such officers had remained in office until delivery.

(c) Any bonds issued pursuant to sections 13b-74 to 13b-77 , inclusive, may be sold at public sale on sealed proposals or by negotiation in such manner, at such price or prices, at such time or times and on such other terms and conditions of such bonds and the issuance and sale thereof as the State Bond Commission may determine to be in the best interests of the state, or the State Bond Commission may delegate to the Treasurer all or any part of the foregoing powers in which event the Treasurer shall exercise such powers unless the State Bond Commission, by adoption of a resolution prior to the exercise of such powers by the Treasurer, shall elect to reassume the same.

(d) The debt service requirements with respect to any bonds and bond anticipation notes issued pursuant to sections 13b-74 to 13b-77 , inclusive, shall be secured by (1) a first call upon the pledged revenues as they are received by the state and credited to the Special Transportation Fund established under section 13b-68 , and (2) a lien upon any and all amounts held to the credit of said Special Transportation Fund from time to time, provided said lien shall not extend to amounts held to the credit of such Special Transportation Fund which represent (A) amounts borrowed by the Treasurer in anticipation of state revenues pursuant to section 3-16 , or (B) transportation-related federal revenues of the state. Any obligation of the state secured by said lien to pay the unrefunded principal of bond anticipation notes, including for this purpose any obligation of the state under a reimbursement agreement entered into in connection with a credit facility providing for payment of the unrefunded principal of bond anticipation notes, shall be subordinate to any obligation of the state secured by said lien to pay (i) the debt service requirements with respect to bonds, or (ii) any debt service requirements with respect to bond anticipation notes other than debt service requirements relating to unrefunded principal of bond anticipation notes or to obligations under a credit facility for the payment of such unrefunded principal.

All expenses incurred in carrying out such trust indenture may be treated as transportation costs, as defined in section 13b-75 . (h) The Treasurer shall have power to purchase bonds and bond anticipation notes of the state issued pursuant to this section out of any funds available therefor.

Proceeds from investments authorized by this subparagraph, less amounts required under the proceedings authorizing the issuance of bonds for the payment of transportation costs relating to such bonds, shall be credited to the Special Transportation Fund created under section 13b-68 . (l) Any bonds issued under the provisions of sections 13b-74 to 13b-77 , inclusive, and any general obligation bonds of the state issued for transportation purposes, as defined in subsection (c) of section 13b-69 , and at any time outstanding may, at any time and from time to time, be refunded by the state by the issuance of its refunding bonds in such amounts as the State Bond Commission may deem necessary, but not to exceed an amount sufficient to refund the principal of the bonds to be so refunded, to pay any unpaid interest on such bonds and any premiums and commissions necessary to be paid in connection with such bonds and to pay costs and expenses which the Treasurer may deem necessary or advantageous in connection with the authorization, sale and issuance of refunding bonds. Any such refunding may be effected whether the bonds to be refunded shall have matured or shall thereafter mature. All refunding bonds issued under this subsection shall be payable solely from the revenues or other receipts, funds or moneys out of which the bonds to be refunded thereby are payable and shall be subject to and may be secured in accordance with the provisions of this section. (m) Whenever the issuance of bonds has been authorized pursuant to sections 13b-74 to 13b-77 , inclusive, the Treasurer may, pending the issuance thereof, and, subject to any applicable terms or provisions of the proceedings authorizing such issuances, issue, in the name of the state, bond anticipation notes and any renewals thereof. Notes evidencing such borrowings shall be designated “Bond Anticipation Notes” and shall be signed by the Treasurer or his deputy. The principal of and interest on any bond anticipation notes issued pursuant to this subsection may be repaid from pledged revenues or other pledged receipts, funds or moneys, to the extent not paid from the proceeds of renewals thereof or of the bonds. Upon the sale of the bonds, the proceeds thereof, to the extent required, shall be applied forthwith to the payment of the principal of and interest on any bond anticipation notes or shall be deposited in trust for such purpose. The date or dates of such bond anticipation notes, the maturities, denominations, form, details and other particulars of such bond anticipation notes, including the method, terms and conditions for the issue and sale thereof, shall be determined by the Treasurer in the best interest of the state, and the Treasurer shall file with the secretary of the State Bond Commission on or before the date of delivery of such bond anticipation notes a certificate of determination setting forth the specific details and particulars of each issue of bond anticipation notes, including renewals thereof. (n) Whenever the state has a written commitment to receive a grant-in-aid or similar form of assistance with respect to a project or program for which the issuance of bonds has been authorized pursuant to sections 13b-74 to 13b-77 , inclusive, the Treasurer may issue notes in anticipation of the issuance of such a grant-in-aid or other assistance, provided (1) the total amount of such notes shall not exceed the amount of the grant commitment which has not been paid to the state and (2) all grant payments with respect to such project or program received by the state, to the extent required, shall be applied promptly toward repayment of such temporary notes as the same shall become due and payable, or shall be deposited in trust for such purpose. Notes evidencing such borrowings shall be designated “Grant Anticipation Notes” and shall be signed by the manual or facsimile signature of the Treasurer or his deputy. The principal of and interest on any grant anticipation notes issued pursuant to this subsection may be repaid from the proceeds of renewals thereof, from grants-in-aid or other assistance pledged for the payment thereof, or from the proceeds of a credit facility including but not limited to, a letter of credit or policy of bond insurance. The Treasurer is hereby authorized to enter into reimbursement agreements or similar agreements with respect to such credit facilities, and the state's obligation under any such credit facility shall be included among the debt service requirements for the applicable period. The date or dates of such grant anticipation notes, the maturities, denomination, form, details and other particulars of such grant anticipation notes, including the method, terms and conditions for the issue and sale thereof, shall be determined by the Treasurer in the best interests of the state, and the Treasurer shall file with the secretary of the State Bond Commission on or before the date of delivery of such bond anticipation notes a certificate of determination setting forth the specific details and particulars of each issue of grant anticipation notes, including renewals thereof. This subsection shall not apply if the grant-in-aid or other assistance is to be paid over a period of years to reimburse the state for a portion of principal due on bonds or bond anticipation notes. (o) The State Bond Commission may make representations and agreements which are necessary or appropriate to ensure the exemption from taxation of interest on bonds or bond anticipation notes issued pursuant to sections 13b-74 to 13b-77 , inclusive, eligibility of such bonds or bond anticipation notes for tax credits or payments from the federal government, or any other desired federal income tax treatment of such bonds or bond anticipation notes, in each case under the Internal Revenue Code of 1986, as amended, or any subsequent corresponding internal revenue code of the United States, including agreements to pay rebates to the federal government of investment earnings derived from the investment of the proceeds of bonds or bond anticipation notes, or may delegate to the Treasurer the authority to make such representations and agreements on behalf of the state.
