VOTING  AGREEMENT,  dated as of November 13, 1995,  by  and  among  IMC
Global  Inc., a Delaware corporation ("Parent"), on the one  hand,  and
Great  American  Management and Investment, Inc., in  its  capacity  as
stockholder  ("Stockholder")  of  The Vigoro  Corporation,  a  Delaware
corporation (the "Company"), on the other hand (this "Agreement");


WHEREAS, concurrently herewith, Parent, Bull Merger Company, a Delaware
corporation and wholly owned subsidiary of Parent, and the Company  are
entering  into an Agreement and Plan of Merger (the "Merger Agreement";
capitalized  terms used without definition herein having  the  meanings
ascribed thereto in the Merger Agreement);


WHEREAS,  concurrently herewith, Parent and the  Company  are  entering
into a Stock Option Agreement (the "Stock Option Agreement");


WHEREAS,  Stockholder is as of the date hereof the beneficial owner  of
Company Common Shares (collectively, the "Shares");


WHEREAS, approval of the Merger Agreement by the Company's stockholders
is a condition to the consummation of the Merger;


WHEREAS,  as  a  condition to its entering into the  Merger  Agreement,
Parent has required that Stockholder agree, and Stockholder has agreed,
to enter into this Agreement; and


WHEREAS,  Stockholder has been informed that the Board of Directors  of
the Company has approved the Merger Agreement.


NOW,  THEREFORE,  in  consideration of the  foregoing  and  the  mutual
covenants and agreements set forth herein, the parties hereto agree  as
follows:


Section 1.  Agreement to Vote, Restrictions on Dispositions, Etc.


a.   Stockholder  hereby  agrees  to  attend  the  Company  Stockholder
Meeting, in person or by proxy, and to vote (or cause to be voted)  all
Shares,  and  any  other  voting securities of the  Company,  owned  by
Stockholder  whether issued heretofore or hereafter, that  such  person
owns  or has the right to vote, for approval and adoption of the Merger
Agreement  (as  amended  from time to time) and  the  Merger,  and  the
transactions  contemplated by the Merger Agreement, such  agreement  to
vote  to  apply  also  to  any adjournment of the  Company  Stockholder
Meeting.  Stockholder agrees not to grant any proxies or enter into any
voting agreement or arrangement inconsistent with this Agreement or the
Limited Irrevocable Proxy of even date herewith executed by Stockholder
in favor of Parent ("Irrevocable Proxy").


b.   Stockholder hereby agrees that, without the prior written  consent
of  Parent, Stockholder shall not, directly or indirectly, sell,  offer
to  sell,  grant  any option for the sale of or otherwise  transfer  or
dispose  of,  or enter into any agreement to sell, any Shares  and  any
other   voting   securities  of  the  Company  that  Stockholder   owns
beneficially or otherwise.  Stockholder agrees that Parent may instruct
the  Company  to enter stop transfer orders with the transfer  agent(s)
and  the registrar(s) of the Company Common Shares against the transfer
of  Shares  and  any  other  voting  securities  of  the  Company  that
Stockholder  owns beneficially or otherwise.  If requested  by  Parent,
Stockholder   agrees  to  surrender  to  the  transfer   agent(s)   and
registrar(s)  of  the  Company Common Shares certificates  representing
Company  Common  Shares  registered in  the  name  of  Stockholder,  in
exchange for certificates representing Company Common Shares containing
a legend to the effect of the following:


The  shares represented by this certificate are subject to restrictions
on  transfer and disposition as set forth in the Voting Agreement dated
as  of November 13, 1995 among IMC Global Inc., a Delaware corporation,
and  Great  American Management and Investment, Inc.  A  copy  of  such
agreement may be obtained from the Secretary of the Company.


Upon  the  termination  of  this  Agreement  pursuant  to  Section   6,
Stockholder shall have the right to unilaterally instruct the  transfer
agent(s)  and registrar(s) of the Company Common Shares to  deliver  to
the   Stockholder  certificates  representing  Company  Common   Shares
registered in the name of the Stockholder and not bearing the foregoing
legend  in exchange for certificates representing Company Common Shares
registered in the name of the Stockholder and bearing such legend.


c.   Stockholder agrees to vote (or cause to be voted) all Shares,  and
any  other  voting  securities  of the Company,  owned  by  Stockholder
whether  issued heretofore or hereafter, that such person owns  or  has
the   right   to  vote,  (i)  against  any  recapitalization,   merger,
consolidation, sale of assets or other business combination or  similar
transaction   involving  the  Company  or  any  of  its   Subsidiaries,
securities  or  assets which is not endorsed in writing by  Parent  and
(ii) any other action or agreement that would result in a breach of any
covenant,  representation  or  warranty  or  any  other  obligation  or
agreement  of  the Company under the Merger Agreement  or  which  could
result in any of the conditions to the Company's obligations under  the
Merger Agreement not being fulfilled.


d.   Stockholder  agrees  not  to directly or  indirectly  solicit,  or
authorize  any person to solicit, any inquiries or proposals  from  any
person other than Parent relating to the merger or consolidation of the
Company with any person other than Parent or its Subsidiaries,  or  the
acquisition  of  the  Company's  or any  of  its  Subsidiaries'  voting
securities by, or the direct or indirect acquisition or disposition  of
a   significant  amount  of  assets  of  the  Company  or  any  of  its
Subsidiaries otherwise than in the ordinary course of business  of  the
Company or such Subsidiary, from or to any person other than Parent  or
its  Subsidiaries or directly or indirectly enter into or continue  any
discussions, negotiations or agreements relating to, or vote (or  cause
to  be  voted)  in  favor of, any such transaction.  Nothing  contained
herein shall be construed to limit or otherwise affect any Affiliate or
representative  of  Stockholder who shall serve as a  director  of  the
Company  from taking any action permitted by Section 4.2 of the  Merger
Agreement in his or her capacity as such director.


e.   Stockholder  agrees to promptly notify Parent in  writing  of  the
nature  and  amount of any acquisition by Stockholder  after  the  date
hereof of any voting securities of the Company.


Section  2.   Securities Act Covenants, Representations and Warranties.
Stockholder  hereby  agrees,  represents  and  warrants  to  Parent  as
follows:


a.   Stockholder will not make any sale, transfer or other  disposition
of  Parent  Common  Stock  received by Stockholder  in  the  Merger  in
violation of the Securities Act.


b.   Stockholder has been advised that the offering, sale and  delivery
of  shares  of  Parent  Common Stock pursuant to  the  Merger  will  be
registered under the Securities Act on a registration statement on Form
S-4.   Stockholder has also been advised, however, that to  the  extent
Stockholder is considered an Affiliate of the Company at the  time  the
Merger  Agreement  is submitted for a vote of the stockholders  of  the
Company,  any public offering or sale by Stockholder of any  shares  of
Parent  Common Stock received by Stockholder in the Merger will,  under
current  law,  require  either (i) the further registration  under  the
Securities  Act  of any shares of Parent Common Stock  to  be  sold  by
Stockholder, (ii) compliance with Rule 145 promulgated by the SEC under
the  Securities Act or (iii) the availability of another exemption from
such registration under the Securities Act.


c.   Stockholder has read this Agreement and the Merger  Agreement  and
has  discussed  their  requirements to the extent Stockholder  believed
necessary, with Stockholder's counsel or counsel for the Company.


d.   Stockholder  understands that stop transfer instructions  will  be
given  to Parent's transfer agents with respect to Parent Common  Stock
and that a legend will be placed on the certificates for the shares  of
Parent  Common  Stock  issued  to  Stockholder,  or  any  substitutions
therefor, to the extent Stockholder is considered an Affiliate  of  the
Company at the time the Merger Agreement is submitted for a vote of the
stockholders of the Company.


Section  3.   Additional Representations and Warranties of Stockholder.
Stockholder  represents and warrants to Parent as follows:  Stockholder
has  all  necessary  power and authority to execute  and  deliver  this
Agreement,  to perform its obligations hereunder and to consummate  the
transactions  contemplated  hereby.   This  Agreement  has  been   duly
executed and delivered by Stockholder.  Assuming the due authorization,
execution  and  delivery  of this Agreement by Parent,  this  Agreement
constitutes  the valid and binding agreement of Stockholder enforceable
against  Stockholder in accordance with its terms,  except  as  may  be
limited   by   applicable   bankruptcy,   insolvency,   reorganization,
moratorium  and  other  similar laws of general application  which  may
affect  the  enforcement of creditors' rights generally and by  general
equitable principles.  The Company Common Shares of Stockholder are the
only voting securities of the Company owned (beneficially or of record)
by  Stockholder  and  are owned free and clear of all  liens,  charges,
encumbrances, restrictions and commitments of any kind. Other than  the
Irrevocable  Proxy,  Stockholder  has  not  appointed  or  granted  any
irrevocable proxy, which appointment or grant is still effective,  with
respect to the Shares.  The execution and delivery of this Agreement by
Stockholder  does not (a) conflict with or violate any agreement,  law,
rule,  regulation,  order,  judgment or decision  or  other  instrument
binding  upon  it,  nor  require any consent, notification,  regulatory
filing  or  approval  or (b) result in any breach of  or  constitute  a
default  (or an event that with notice or lapse of time or  both  would
become  a  default) under, or give to others any rights of termination,
amendment,  acceleration or cancellation of, or result in the  creation
of  a  lien  or  encumbrance on any of the Shares owned by  Stockholder
pursuant  to, any note, bond, mortgage, indenture, contract, agreement,
lease, license, permit, franchise or other instrument or obligation  to
which  Stockholder  is a party or by which Stockholder  or  the  Shares
owned  by  Stockholder are bound or affected.  Stockholder acknowledges
that  the  restrictions  imposed  upon  it  are  so  imposed  only   in
Stockholder's capacity as a stockholder of the Company.


Section  4.  Further Assurances.  Each party shall execute and  deliver
such  additional  instruments and other documents and shall  take  such
further  actions  (including,  without  limitation,  in  the  case   of
Stockholder,  any  amendments  to  this  Agreement  which  Parent   may
reasonably  request) as may be necessary or appropriate to  effectuate,
carry  out  and  comply  with  all  of  their  obligations  under  this
Agreement.   Without limiting the generality of the foregoing,  neither
of the parties hereto shall enter into any agreement or arrangement (or
alter,  amend  or  terminate any existing agreement or arrangement)  if
such  action  would materially impair the ability of  either  party  to
effectuate, carry out or comply with all the terms of this Agreement.


Section   5.    Representations  and  Warranties  of  Parent.    Parent
represents  and  warrants  to Stockholder as  follows:   Each  of  this
Agreement  and the Merger Agreement has been approved by the  Board  of
Directors  of Parent.  Each of this Agreement and the Merger  Agreement
has  been  duly executed and delivered by a duly authorized officer  of
Parent.  Assuming the due authorization, execution and delivery of this
Agreement by Stockholder and the Merger Agreement by the Company,  each
of  this  Agreement and the Merger Agreement constitutes  a  valid  and
binding  agreement of Parent, enforceable against Parent in  accordance
with  its  terms,  except  as may be limited by applicable  bankruptcy,
insolvency,  reorganization,  moratorium  and  other  similar  laws  of
general  application  which  may affect the enforcement  of  creditors'
rights generally and by general equitable principles.


Section 6.  Effectiveness and Termination.  It is a condition precedent
to  the effectiveness of this Agreement that the Merger Agreement shall
have been executed and delivered and be in full force and effect.  This
Agreement shall automatically terminate and be of no further  force  or
effect:   (i)  upon the close of business on August 14,  1996,  if  the
Merger  shall  not have been effected by such time, or  (ii)  upon  the
earlier  termination  of the Merger Agreement in  accordance  with  its
terms,  or (iii) immediately prior to the Company Stockholder  Meeting,
if  Parent has: (a) pursuant to the exercise of the Option (as  defined
in the Stock Option Agreement), acquired Optioned Shares (as defined in
the   Stock  Option  Agreement);  provided  that,  if,  prior  to   the
acquisition of Optioned Shares, a record date has been established  for
the  vote  of  stockholders of the Company with respect to  any  matter
described in paragraph a or b of Section 1, this Agreement shall remain
in  effect with respect to such vote; and (b) the full legal right  and
authority  to vote all such Optioned Shares at the Company  Stockholder
Meeting  for  approval  and adoption of the Merger  Agreement  and  the
Merger,  and  the  transactions contemplated by the  Merger  Agreement.
Notwithstanding  anything  contained  in  clause  (iii)  above  to  the
contrary,  this Voting Agreement shall not terminate if the Option  has
been  exercised  for  less than all of the Optioned  Shares;  provided,
however,  that from and after any partial exercise of the Option,  this
Agreement  shall relate to the number of Shares equal to (i) the  total
number  of  Shares  initially subject hereto less  (ii)  the  aggregate
number  of  Optioned  Shares as to which the  Option  shall  have  been
exercised.   Upon  any termination of this Agreement,  except  for  any
rights  either party may have in respect of any breach by either  party
of its obligations hereunder, none of the parties hereto shall have any
further obligation or liability hereunder.  The provisions of Section 1
of  this Agreement shall terminate and be of no further force or effect
from and after the Effective Time of the Merger.


Section  7.   Covenants of Stockholder Not to Enter  Into  Inconsistent
Agreements.  Stockholder hereby agrees that, except as contemplated  by
this  Agreement,  the  Irrevocable  Proxy  and  the  Merger  Agreement,
Stockholder  shall  not  enter into any voting agreement  or  grant  an
irrevocable proxy or power of attorney with respect to the Shares which
is inconsistent with this Agreement.


Section 8.  Miscellaneous.


a.    Notices,   Etc.    All  notices,  requests,  demands   or   other
communications  required by or otherwise given  with  respect  to  this
Agreement  shall be in writing and shall be deemed to  have  been  duly
given to either party when delivered personally (by courier service  or

among  the parties relating to the subject matter hereof and supersedes
all  prior  agreements  and  understandings relating  to  such  subject
matter.  There are no representations, warranties or covenants  by  the

unenforceable)  that will be valid and enforceable and will  carry  out
the parties' intentions hereunder.


f.   Specific Performance.  The parties acknowledge that money  damages

Agreement  or prevent any violation hereof and, to the extent permitted
by applicable law, each party waives any objection to the imposition of
such relief.


g.   Remedies  Cumulative.  All rights, powers  and  remedies  provided
under this Agreement or otherwise available in respect hereof at law or
in  equity shall be cumulative and not alternative, and the exercise or
beginning  of  the exercise of any thereof by either  party  shall  not
preclude  the simultaneous or later exercise of any other such  rights,
power or remedy by such party.


h.   No  Waiver.   The failure of either party hereto to  exercise  any
right,  power  or  remedy  provided under this Agreement  or  otherwise
available  in  respect hereof at law or in equity, or  to  insist  upon
compliance  by  the other party hereto with its obligations  hereunder,
and  any  custom or practice of the parties at variance with the  terms
hereof,  shall not constitute a waiver by such party of  its  right  to
exercise  any  such or other right, power or remedy or to  demand  such
compliance.


i.  No Third Party Beneficiaries.  This Agreement is not intended to be
for the benefit of and shall not be enforceable by any person or entity

exclusive  jurisdiction  of  the Court of  Chancery  in  the  State  of
Delaware  in any action, suit or proceeding arising in connection  with
this  Agreement,  and agrees that any such action, suit  or  proceeding
shall be brought only in such court (and waives any objection based  on
forum non conveniens or any other objection to venue therein) provided,
however,  that such consent to jurisdiction is solely for  the  purpose
referred  to  in this paragraph (j) and shall not be deemed  to  be  in
general submission to the jurisdiction of said Court or in the State of
Delaware  other than for such purposes.  Each party hereto  waives  any
right  to a trial by jury in connection with any such action,  suit  or
proceeding.


k.   Governing Law.  This Agreement and all disputes hereunder shall be
governed  by and construed and enforced in accordance with the internal

of law.

counterparts, each of which shall be deemed to be an original, but  all
of  which  together shall constitute one instrument.  Each  counterpart
may  consist  of a number of copies each signed by less than  all,  but
together signed by all, the parties hereto.


n.   Expenses.   Each  party shall bear its own  expenses  incurred  in

The  undersigned  stockholder  of The Vigoro  Corporation,  a  Delaware
corporation  (the "Company"), hereby irrevocably appoints  IMC  Global,
Inc., a Delaware corporation ("Parent"), the attorney-in-fact and proxy
of  the undersigned, within the limitations of this Proxy, with respect
to  shares  of Common Stock, $.01 par value per share, of  the  Company
owned  of  record  or beneficially by the undersigned  (the  "Shares").
Upon  the  execution hereof, all prior proxies given by the undersigned
with respect to the Shares are hereby revoked and no subsequent proxies
will  be  given.   This Proxy is irrevocable (to the  extent  permitted
under  Delaware law), and coupled with an interest and  is  granted  in
consideration of the Company and Parent entering into the Agreement and
Plan  of  Merger dated November 13, 1995 among Parent, Bull Merger  Co.
and the Company (the "Merger Agreement").  The attorney and proxy named
above  will be empowered at any time prior to the earliest of  (i)  the
effectiveness  of the Merger as defined in the Merger  Agreement,  (ii)
August  14,  1996,  (iii)  notice from Parent  that  Parent  elects  to
terminate  this  Proxy or (iv) the termination of the Voting  Agreement
(as  defined in the Merger Agreement) in accordance with its terms,  to
exercise  all  voting and other rights to the extent specified  in  the
succeeding  paragraph; provided, however, that, in the event  that  the
number of Shares subject to the Voting Agreement is reduced pursuant to
the  provisions of Section 6 thereof, then this Proxy shall  thereafter
be  deemed  to  relate  only to such number of  Shares  then  remaining
subject  to the Voting Agreement.  Upon the occurrence of  the earliest
of  the foregoing events described in clauses (i), (ii), (iii) or  (iv)
above, this Proxy shall expire and be of no further force or effect.


The attorney and proxy named above may only exercise this proxy to vote
the  Shares subject hereto in favor of approval of the Merger Agreement
and  the  Merger at any annual, special or other meeting of the holders
of   capital  stock  of  the  Company  and  any  adjournments   thereof
(including,  without  limitation, the  power  to  execute  and  deliver
written  consents  with respect to the Shares) or for  the  purpose  of
voting  against a business combination of the Company  or  any  of  its
subsidiaries and affiliates with any party other than Parent or any  of
its  subsidiaries and affiliates and may not exercise this Proxy on any
other matters.  The undersigned stockholder may vote the Shares on  all
other matters.  The undersigned will, upon request, execute and deliver
any additional documents deemed by the above-named attorney-in-fact and
proxy  to  be  necessary or desirable to effect the limited irrevocable
proxy created hereby.
