Be it enacted by the Senate and House of Representatives in General Court assembled, and by the authority of the same, as follows:

Notwithstanding the provisions of any general or special law to the contrary and in order to promote the public good, the city of Quincy retirement board is hereby authorized and directed to credit Fred J. Prezioso with creditable service, for the period from January 1976 to March 1978, inclusive, for the purpose of determining his superannuation retirement allowance pursuant to the provisions of paragraph (a) of subdivision (2) of section 5 of chapter 32 of the General Laws; provided, however, that before the date any retirement allowance becomes effective for him, he shall pay into the annuity savings fund of the city of Quincy retirement system in one sum or installments, upon such terms and conditions as the board may prescribe, an amount equal to that which would have been withheld as regular deductions from his regular compensation for such previous service, plus interest.
