SECTION 2 DIVIDENDS 2.1 Payment of Dividends The holders of the Preferred Stock, Series B shall be entitled to receive, and the Corporation shall pay thereon, as and when declared by the board of directors out of monies properly applicable to the payment of dividends, fixed cumulative preferential cash dividends at the rate of 5% per share per annum (the "Dividend Payment") on the amount paid-up thereon payable in arrears on December 31 of each year (the "Dividend Payment Date"). Dividends on the Preferred Stock, Series B shall accrue from and including the date of issuance. Cheques of the Corporation or its dividend paying agent payable at par at a chartered bank or trust company shall be issued in respect of such dividends to the holders of the Preferred Stock, Series B entitled thereto. The mailing of such cheques shall satisfy and discharge all liability for the dividends represented thereby, unless the cheques are not paid on due presentation.

The holders of the Preferred Stock, Series B shall not be entitled to any dividends other than or in excess of the cash dividends provided for herein. A dividend which is represented by a cheque which has not been presented for payment within six years after it was issued shall be forfeited to the Corporation. 2.2 Dividend for Other than a Full Year The amount per share of the dividend accrued for any period which is less than a full year with respect to any Preferred Stock, Series B: 2 (a) which is issued, redeemed or purchased; or (b) where the assets of the Corporation are distributed to the holders of Preferred Stock, Series B on the liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary, or on any other distribution of assets of the Corporation among its shareholders for the purpose of winding up its affairs, shall be equal to the amount (rounded to the nearest 1/100th of 1 cent) calculated by multiplying the Dividend Payment by a fraction of which the numerator is the number of days during the year that the share has been outstanding (including the date of issuance or the first day of the year as well as the Dividend Payment Date or date of redemption, purchase, or distribution of assets, as applicable) and the denominator is 365. 2.3 Interest Payment The holders of the Preferred Stock, Series B shall be entitled to receive, as provided herein, an amount equivalent to interest at the rate of 8% per annum on the amount of all Dividend Payments not paid on their respective Dividend Payment Dates and which remain outstanding from time to time, which shall be compounded annually on each Dividend Payment Date (the "Interest Amount"). SECTION 3 REDEMPTION AND PURCHASE 3.1 General Subject to Section 6, the Preferred Stock, Series B may be redeemed or purchased by the Corporation as provided in this Section, but not otherwise. 3.2 Redemption Rights (a) Subject to Section 6, the Corporation may at its option redeem at any time all or from time to time any number of the outstanding Preferred Stock, Series B on payment of the Redemption Price as provided in Section 3.3.

(b) On and after the date fixed for redemption, the Corporation shall pay or cause to be paid the Redemption Price to or to the order of the holders of the Preferred Stock, Series B redeemed on presentation and surrender, at the place of redemption, of the respective certificates representing such shares, and the holders of the Preferred Stock, Series B called for redemption shall cease to be entitled to dividends or to exercise any of the rights of holders in respect thereof, unless payment of the Redemption Price shall not be made in accordance with the foregoing provisions, in which case the rights and privileges of the holders shall remain unimpaired. (c) The Corporation shall have the right at any time after mailing the Redemption Notice to deposit the Redemption Price of the shares thereby called for redemption, or such part thereof as at the time of deposit has not been claimed by the shareholders entitled thereto, in a special account with a chartered bank or trust company for the holders of such shares, and upon the deposit being made or upon the date fixed for redemption, whichever is the earlier, the Preferred Stock, Series B in respect of which the deposit shall have been made shall be deemed to be redeemed and the rights of each holder thereof shall be limited to receiving, without interest, his proportionate part of the Redemption Price so deposited upon presentation and surrender of the certificates representing his shares so redeemed.
