                                  SCHEDULE "A"

      The rights, privileges, restrictions and conditions attaching to the
Common Shares shall be as follows:

(a)   The holders of the Common Shares shall be entitled to one (1) vote per
share at all meetings of the Shareholders of the Corporation;

(b)   Subject to the prior rights of the holders of the Special Shares, the
holders of the Common Shares shall be entitled to receive any dividends declared
by the Corporation;

(c)   Subject to the prior rights attaching to the Special Shares, in the event
of the liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, the holders of the Common Shares shall be entitled to
all the remaining assets of the Corporation.

      The rights, privileges, restrictions and conditions attaching to the
Special Shares shall be as follows:

(a)   Subject to the Act, the holders of the Special Shares shall not as such
have any voting rights for the election of Directors or for any other purpose,
nor shall they be entitled to attend meetings of Shareholders or to receive
notice of meetings of the Shareholders of the Corporation;

(b)   The holders of the Special Shares shall in each year, in the discretion of
the Directors of the Corporation, but always in preference and priority to any
payment of dividends on the Common Shares for such year, be entitled, out of any
or all profits or surplus available for dividends, to non-cumulative dividends
at the rate of 8% per annum. If in any year, after providing for the full
dividend on the Special Shares, there shall remain any profits or surplus
available for dividends, the whole or any part thereof may, in the discretion of
the Directors, be applied to dividends on the Common Shares. The Special Shares
shall not be entitled to any dividend other than, or in excess of, the
non-cumulative dividends at the rate of 8% per annum hereinbefore provided for;

entitled to share in any further distribution of the property or assets of the
Corporation;

(d)   Subject to the Act, the Corporation may upon giving notice as hereinafter
provided, redeem at any time the whole or any part of the then outstanding
Special Shares on payment for each share to be redeemed of $1.00, together with
all declared and unpaid dividends. In case a part only of the then outstanding
Special Shares are at any time to be redeemed, pursuant to this clause of
Schedule A, the shares so to be redeemed shall be redeemed pro rata in
proportion to the number of Special Shares held by the holders thereof,
provided that the Corporation shall not be required to pay off or redeem any
fractions of shares and that the Directors may depart from such pro rata
redemption in such manner and to such extent as may seem to them advisable in
order to avoid fractions;

redemption. Such Special Shares shall thereupon be and be deemed to be redeemed
and shall be restored to the status of authorized but unissued shares. If only
part of the shares represented by any certificate be redeemed, a new certificate
for the balance shall be issued at the expense of the Corporation;

(g)   From and after the date specified in any such notice, the Special Shares
called for redemption shall cease to be entitled to dividends and the holders
shall not be entitled to exercise any of the rights of Shareholders in respect
thereof unless payment of the redemption price shall not be made upon
presentation of certificates in accordance with the foregoing provisions, in
which case the rights of the holders shall remain unaffected;

(h)   Should the holders of any of the Special Shares so called for redemption
fail to present the certificate or certificates representing the Special Shares
on the date specified for redemption the

                                                                               3
