(70 ILCS 3615/5.05) (from Ch. 111 2/3, par. 705.05)
    Sec. 5.05. Opt Out.
    (a) Notwithstanding any other provision of this Act, if the County Board of the County of DuPage, Kane, Lake, McHenry or Will by ordinance authorizes that such county shall elect to terminate the powers of the Authority and the Suburban Bus Division in that County, the Secretary of such County Board shall certify that proposition to the proper election officials, who shall submit such proposition at an election in accordance with the general election law to decide whether or not the County shall opt out; and if a majority of the voters voting upon the proposition is in favor of terminating the powers of the Authority and the Suburban Bus Division those powers shall be terminated.
    The form of the ballot to be used at the referendum shall be substantially as follows:
--------------------------------------------------------------
    Shall ..... County Terminate the
Powers of the Regional Transportation        YES
Authority and the Suburban Bus          ----------------------
Division in .... County                       NO
on ..... (date)
--------------------------------------------------------------
    If a majority of the voters vote in favor of terminating the powers of the Authority and the Suburban Bus Division then all of the powers of the Authority and the Suburban Bus Division shall terminate in such county except those powers and functions which the Authority determines to be necessary to exercise with regard to:
        (i) public transportation by commuter rail, and
    
related public transportation facilities;
        (ii) public transportation other than by commuter
    
rail which is required in order to comply with federal or State laws and regulations, and related public transportation facilities; and
        (iii) public transportation other than by commuter
    
rail provided by the Suburban Bus Division pursuant to contract with the County or other governmental entity therein, and related public transportation facilities.
    (b) The termination of the powers of the Authority and the Suburban Bus Division referred to in paragraph (a) of this Section with respect to any County shall occur on approval of the referendum by the electors provided on or prior to the date of such termination, such County shall have:
        (i) assumed the obligations of the Authority under
    
all laws, federal or State, and all contracts with respect to public transportation or public transportation facilities in such County, which statutory or contractual obligations extend beyond the termination date provided for in accordance with paragraph (c) of this Section provided that such obligations shall not be deemed to include any indebtedness of the Authority for borrowed money;
        (ii) agreed to indemnify and hold harmless the
    
Authority against any and all claims, actions and liabilities arising out of or in connection with the termination of the Authority's powers and functions pursuant to paragraph (a) of this Section; and
        (iii) taken or caused to be taken all necessary
    
actions and fulfilled or caused to be fulfilled all requirements under federal and State laws, rules and regulations with respect to such termination and any related transfers of assets or liabilities of the Authority. A County may, by mutual agreement with the Authority, permit the Authority to fulfill one or more contracts which by their terms extend beyond the termination date provided for in accordance with paragraph (c) of this Section, in which case the powers and functions of the Authority in that County shall survive only to the extent deemed necessary by the Authority to fulfill said contract or contracts. The satisfaction of the requirements provided for in this paragraph shall be evidenced in such manner as the Authority may require.
    (c) Following an election to terminate the powers of the Authority and the Suburban Bus Division at a referendum held under paragraph (a) of this Section the County Board shall notify the Authority of the results of the referendum which notice shall specify a termination date, which is the last day of the calendar month, but no earlier than December 31, 1984. Unless the termination date is extended by mutual agreement between the County and the Authority, the termination of the powers and functions of the Authority in the County shall occur at midnight on the termination date, provided that the requirements of this Section have been met.
    (d) The proceeds of taxes imposed by the Authority under Sections 4.03 and 4.03.1 collected after the termination date within a County wherein the powers of the Authority and the Suburban Bus Division have been terminated under this Section shall be provided by the Authority to the Commuter Rail Board to support services under the jurisdiction of the Commuter Rail Board which are attributable to that County, as determined by the Commuter Rail Board. Any proceeds which are in excess of that necessary to support such services shall be paid by the Authority to that County to be expended for general transportation purposes in accordance with law. If no services under the jurisdiction of the Commuter Rail Board are provided in a County wherein the powers of the Authority have been terminated under this Section, all proceeds of taxes imposed by the Authority in the County shall be paid by the Authority to the County to be expended for general transportation purposes in accordance with law. The Authority or the Suburban Bus Division has no obligation to see that the funds expended under this paragraph by the County are spent for general transportation purposes in accordance with law.
