As additional security for any issue of refunding bonds hereunder, or any part thereof, any municipality may by resolution of its governing body confer upon the holders of the refunding bonds all rights, powers and remedies which the holders would be entitled to if they were the owners and had possession of the notes, bonds or other obligations for the refinancing of which such refunding bonds shall have been issued, including, but not limited to, the preservation of the lien of such notes, bonds or other obligations without extinguishment, impairment or diminution thereof. In the event any municipality exercises the power conferred by this section (a) each refunding bond shall contain a recital to the effect that the holder thereof has been granted the additional security provided by this section and (b) each note, bond, certificate or other obligation of the municipality to be refinanced by any such refunding bonds shall be kept intact and shall not be cancelled or destroyed until the refunding bonds, and interest thereon, have been finally paid and discharged but shall be stamped with a legend to the effect that such note, bond, certificate or other obligation has been refunded pursuant to The Revenue Bond Refinancing Act of 1937.
