(b) Remedies For Nonpayment. If on any Series B Redemption Date, all of the Shares elected to be redeemed pursuant to a Series B Election Notice are not redeemed in full by the Corporation by paying the entire Series B Redemption Price, until such Shares are fully redeemed and the aggregate Series B Redemption Price paid in full, (i) all of the unredeemed Shares shall remain outstanding and continue to have the rights, preferences and privileges expressed herein, including the accrual and accumulation of dividends thereon as provided in Section 4, (ii) interest on the portion of the aggregate Series B Redemption Price applicable to the unredeemed Shares shall accrue daily in arrears at a rate equal to the lesser of (x) 4.0% or (y) the prime rate, as published in the Eastern Edition of the Wall Street Journal per annum, compounded quarterly.

To the extent that such Shares are certificated, each surrendered certificate shall be canceled and retired and the Corporation shall thereafter make payment of the applicable Series B Redemption Price by certified check or wire transfer to the holder of record of such certificate; provided, however, that if less than all the Shares represented by a surrendered certificate are redeemed, then a new stock certificate representing the unredeemed Shares shall be issued in the name of the applicable holder of record of canceled stock certificate.

8.5 No Rights Subsequent to Redemption. If on the applicable Series B Redemption Date, the Series B Redemption Price is paid (or tendered for payment) for any of the Shares to be redeemed on such Series B Redemption Date, then on such date all rights of the holder in the Shares so redeemed and paid or tendered, including any rights to dividends on such Shares, shall cease, and such Shares shall no longer be deemed issued and outstanding.
