convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors) and has not been a party to a civil proceeding of a judicial or

             The Corporation acquired ownership of 39,361,786 common shares of
Repadre Capital Corporation ("Repadre"), representing 100 per cent of the
outstanding common shares of Repadre, in exchange for 1.6 common shares of
IAMGold for each one common share of Repadre (the "Transaction"), resulting in
the Corporation issuing from treasury an aggregate of 62,978,756 common shares
of the Corporation. The Transaction became effective on January 7, 2003.
Reference is made to the Form 6-K dated November 8, 2002 of Repadre for
information regarding the Transaction. As a result of the completion of the
Transaction, the proportion of the outstanding common shares of the Corporation
controlled by Mr. Nathanson has decreased. This report is being filed for

         The securities of the Corporation controlled by Mr. Nathanson are held

any additional securities of the Corporation. Mr.


                                       3





Nathanson  intends  to  review  his  investment  in  the  Corporation  on a
continuing  basis and may increase or decrease his holding of  securities of the
Corporation in the future.  Any such increase or decrease will depend on various
factors, including, among other things, the price and availability of securities
of the  Corporation,  subsequent  developments  affecting the Corporation or its
business, other available investments and business opportunities,  general stock
market and economic  conditions,  tax  considerations  and  required  regulatory
approvals.

                Other than discussed above, Mr. Nathanson currently has no plans
to effect any of the transactions required to be described in Item 4 of Schedule
13D.

the outstanding common shares of the Corporation. In addition, Mr. Nathanson
holds options to acquire 470,000 common shares of the Corporation. Assuming the
exercise of all of such options, Mr. Nathanson would beneficially own or
exercise control or direction over an aggregate of 7,744,946 common shares of
the Corporation, representing approximately 5.4 per cent of the then outstanding
common shares of the Corporation.

knowledge of any arrangements, undertakings or relationships (legal or
