Dear Bob:

     Attached is a term sheet setting forth the principal terms and conditions
of our proposal for a stock merger (the "Merger") of Freeport-McMoRan Inc. and
IMC Global Inc.  If you indicate your acceptance of the attached term sheet by
executing in the space provided below, this letter, together with the term 
sheet, will constitute the mutual nonbinding statement of the intention of
Freeport-McMoRan Inc. and IMC Global Inc. to effect the Merger.

     There will be a period commencing on the date that this letter has been
executed by you and ending on August 31, 1997, during which (i) each of the
parties will complete its due diligence and evaluation of the other party and
(ii) the parties will use their reasonable good faith efforts to negotiate a
mutually acceptable definitive agreement to effect the Merger.  Except for the
obligations set forth in the foregoing sentence, neither this letter nor the 
term sheet shall be deemed to be a binding agreement of the parties nor shall 
such instruments create any legal obligation on behalf of Freeport-McMoRan 
Inc., IMC Global Inc. or any of their respective representatives.  Any such 
agreement shall be created solely by a written, executed and delivered 
definitive agreement.

     Please confirm your acceptance of our proposal by executing two copies of
this letter and returning a fully executed copy to Freeport-McMoRan Inc.  We
would intend to mutually publicly announce the proposed transaction immediately
thereafter.  It is our expectation that the parties would enter into a 
definitive agreement within one month after your execution and return of this 
letter, that the necessary stockholders meetings will be held as soon as 
practicable thereafter and that the closing will take place as soon as 
practicable after such meetings.

                                   Freeport-McMoRan Inc.
