Whenever refunding Bonds are issued to refund Bonds, the proceeds of which were used to make Authority loans, the Authority may reduce the amount it is owed by the institutions of higher education or education loan corporations which had received Authority Loans from the proceeds of the refunded Bonds. Such institutions of higher education and education loan corporations may use this reduced amount to reduce the amount of interest being paid on Education Loans which the institutions and education loan corporations had made pursuant to the Authority Loans from the proceeds of the refunded Bonds.
