3.1      The Corporation may issue an unlimited number of Common Shares without
         par value (herein called "Common Shares") and an unlimited number of
         Class A Common Shares without par value (herein called "Class A Common
         Shares").

3.2      The Common Shares and the Class A Common Shares shall each carry and be
         subject to the following rights, privileges, restrictions and
         conditions:

         3.2.1    To vote at all meetings of shareholders except meetings of
                  shareholders at which holders of a specified class of shares
                  only are entitled to vote. A shareholder shall have one (1)
                  vote in respect of each share held.

         3.2.2    To receive ratably, subject to the rights of the holders of
                  another class of shares, any dividend declared by the
                  Corporation.

         3.2.3    To receive ratably, subject to the rights of the holders of
                  another class of shares, the remaining property of the
                  Corporation on the liquidation, dissolution or winding-up of
                  the Corporation, whether voluntary or involuntary, save and
                  except that the holders of the Class A Common Shares shall be
                  entitled to receive from the assets of the Corporation such
                  amount in cash and/or assets at undepreciated cost or book
                  value on the balance sheet whichever is greater.

         3.2.4    Any shareholder holding a fractional share issued by the
                  Corporation is entitled to exercise voting rights and to
                  receive dividends in respect of the fractional share.

3.3      The following provisions shall apply with respect to the Common Shares
         authorized, issued and outstanding from time to time. The Corporation
         shall not issue Common Shares unless IMC Potash Carlsbad Inc., a
         corporation incorporated in the State of Deleware, United States of
         America ("IMC Carlsbad"), shall in connection therewith issue common
         shares ("IMC Carlsbad Common Shares") in equal number, and each such
         Common Share and IMC Carlsbad Common Share shall be registered in the
         name of the same person or persons and issued to such person or persons
         subject to the condition that such Common Shares and IMC Carlsbad
         Common Shares shall only be transferable, repurchasable, or redeemable
         and otherwise dealt with together. The Corporation will not take any
         action which will result in an increase or decrease in the number of
         Common Shares issued and outstanding (including, but not limited to,
         through purchase, exchange, reclassification, reorganization,
         consolidation, merger, split, reverse split, or dividend) unless in
         connection therewith there is a commensurate increase or decrease, as
         applicable, in the number of RAC Carlsbad Common Shares issued and
         outstanding such that each issued and outstanding Common Share
         continues to have an associated issued and outstanding IMC Carlsbad
         Common Share. The Common Shares shall not be transferable (including
         transfers to or by the Corporation) and shall not be transferred on the
         books of the Corporation, unless in connection therewith a transfer is
         made by the same transferor to the same transferee of an equal number
         of IMC Carlsbad Common Shares. Each certificate representing Common
         Shares shall contain or have affixed a
