For the purpose of carrying out a financing authorized under sections 7-620 to 7-620e, inclusive, a municipality may issue bonds which are payable solely from and secured by a pledge of and lien upon any or all of the income, proceeds, revenues and property provided as security for the repayment of loans by borrowers financing enterprise zone facilities or by lenders relending bond proceeds in a “loans to lenders” program or any combination thereof as provided in the Internal Revenue Code. Bonds issued pursuant to sections 7-620 to 7-620e, inclusive, shall be special obligations of the municipality and shall not be payable from or charged upon any funds other than the revenues pledged to the payment thereof, nor shall the municipality issuing the same be subject to any liability thereon except to the extent of such pledged revenues. No holder or holders of any bonds shall have the right to compel any exercise of the taxing power of the municipality to pay any bonds or the interest thereon, or to enforce payment thereon against any property of the municipality and the bonds shall not constitute a charge, lien or encumbrance, legal or equitable, upon any property of the municipality. The substance of such limitation shall be plainly stated on the face of each bond. Bonds issued pursuant to sections 7-620 to 7-620e, inclusive, shall not be subject to any statutory limitation on the indebtedness of the municipality and such bonds when issued shall not be included in computing the aggregate indebtedness of the municipality in respect to and to the extent of any such limitation.
