COMMON SHARES

Each holder of common shares shall be entitled to receive notice of and to attend all meetings of shareholders of the Corporation and to vote thereat, except meetings at which only holders of a specified class of shares (other than common shares) or specified series of shares are entitled to vote. At all meetings of which notice must be given to the holders of the common shares, each holder of common shares shall be entitled to one vote in respect of each common share held by such holder.

The holders of the common shares shall be entitled, subject to the rights, privileges, restrictions and conditions attaching to any other class or series of shares of the Corporation, to receive any dividend declared by the Corporation.

The holders of the common shares shall be entitled, subject to the rights, privileges, restrictions and conditions attaching to any other class or series of shares of the Corporation, to receive the remaining property of the Corporation on a liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary.

PREFERRED SHARES. ISSUABLE IN SERIES

The directors of the Corporation may, at any time and from time to time, issue the Preferred Shares in one or more series.

Subject to the following provisions, and subject to the filing of articles of amendment in prescribed form and the endorsement thereon of a certificate of amendment, in accordance with the Canada Business Corporations Act, before the first shares of a particular series are issued, the directors of the Corporation shall fix the number of shares in such series and shall determine, subject to any limitations set out in the articles of the Corporation, the designation, rights, privileges, restrictions and conditions attaching to the shares of such series including, without limiting the generality of the foregoing, any right to receive dividends (which may be cumulative, non-cumulative or partially cumulative and variable or fixed), the rate or rates, amount or method or methods of calculation of preferential dividends and whether such rate or rates, amount or method or methods of calculation shall be subject to change or adjustment in the future, the currency or currencies of payment, the date or dates and place or places of payment thereof and the date or dates from which such preferential dividends shall accrue, the rights of redemption (if any) and the redemption price and other terms and conditions of redemption, the rights of retraction (if any) and the prices and other terms and conditions of any rights of retraction and whether any additional rights of retraction may be provided to such holders in the future, the voting rights (if any) and the conversion or exchange rights (if any) and any sinking fund, purchase fund or other provisions attaching thereto. Before the first shares of a particular series are issued, the directors of the Corporation may change the rights, privileges, restrictions and conditions attaching to such unissued shares.

Before the issue of the first shares of a series, the board of directors of the Corporation shall send to the Director (as defined in the Canada Business Corporations Act) articles of amendment containing a description of such series including the designations, rights, privileges, restrictions and conditions determined by the directors.

No rights, privileges, restrictions or conditions attaching to a series of Preferred Shares shall confer upon a series a priority over any other series of Preferred Shares in respect of redemption, the payment of dividends, the return of capital or the distribution of assets in the event of the liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary.

The Preferred Shares of each series shall rank on parity with the Preferred Shares of every other series with respect to priority in redemption, the payment of dividends, the return of capital and

The Preferred Shares shall be entitled to priority over the common shares and any other shares of any other class of the Corporation ranking junior to the Preferred Shares with respect to priority in the payment of any dividends.

In the event of the liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, or any other distribution of the assets of the Corporation among its shareholders for the purpose of winding up its affairs, the holders of the Preferred Shares of any series shall be entitled, after payment or provision for payment of the debts and other liabilities of the Corporation as may be required by law:

The Preferred Shares of any series may also be given such other preferences, not inconsistent with the articles of the Corporation over the common shares and any other shares of the Corporation ranking junior to the Preferred Shares as may be determined in the case of such series of Preferred Shares in accordance with paragraph 2 hereof.

The Preferred Shares of any series may be made convertible into or exchangeable for common shares of the Corporation.

The rights, privileges, restrictions and conditions attached to the Preferred Shares of any series may include the right to receive a dividend concurrently with any dividend declared on any other class or series of shares of the Corporation, to be calculated in the manner set forth in the rights, privileges, restrictions and conditions attached to the shares of such series of Preferred Shares.

Except as may be otherwise provided in the articles of the Corporation or as otherwise required by law or in accordance with any voting rights which may from time to time be attached to any series of Preferred Shares, the holders of Preferred Shares as a class shall not be entitled as such to receive notice of, nor to attend or vote at any meeting of the shareholders of the Corporation.
