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

Notwithstanding any general or special law to the contrary, Robert W. Aylward shall be eligible to be reinstated as a member in service of the teachers' retirement system as of the effective date of this act if he repays to the teachers' retirement system an amount equal to the total amount of any retirement allowance received by him together with interest thereon, such repayment to be made in 1 sum or in installments as the teachers' board of retirement shall prescribe. Upon such reinstatement, regular deductions shall be made from his regular compensation pursuant to paragraphs (b) and (b½) of subdivision (1) of section 22 of chapter 32 of the General Laws, for purposes of which his date of entry into service shall be the date he waived his retirement allowance. Upon completion of such repayment, said Robert W. Aylward shall be entitled to creditable service for all periods for which deductions were made from his regular compensation.

Upon reinstatement as a member in service of the teachers' retirement system, Robert W. Aylward shall be eligible, upon the payment of regular deductions together with interest thereon, to establish creditable service with the system for the period of service during which he previously waived his retirement allowance. Such payment will be made in 1 sum.

If Robert W. Aylward retires again before the completion of made payments, he shall, in addition to credit for his actual membership service rendered since the date of his reinstatement under this act, be entitled to credit for the portion of his payments actually made, together with regular interest thereon to the date such retirement becomes effective, bears to the total amount of what his make-up payments, together with regular interest thereon to such latter date, would have been had he made payment thereof in 1 sum on such latter date. Any pension allowance, or other retirement benefit provided under this act shall be exclusive of and in the alternative to any other pension, allowance, or other retirement benefit, including any provided for under general or special law.
