Gentlemen:


         This letter sets forth the understanding among each of you and Eridania
Beghin-Say,  S.A., a  corporation  organized  under the laws of France  ("EBS"),
concerning the following transactions (the "Proposed Transactions"):

         (i) EBS and a  subsidiary  of EBS  ("Subsidiary  I") will  enter into a
stock purchase agreement with all of the holders of common stock of GIH Corp., a
Delaware corporation ("GIH"), including you, pursuant to which Subsidiary I will
agree to purchase all of the outstanding  shares of common stock of GIH at a per
share price  calculated  based on an  underlying  value of $40 for each share of
common stock of American  Maize-Products Company ("American Maize") owned by GIH
less the value of any  disclosed  liabilities  of GIH (the "GIH  Stock  Purchase
Agreement").  It is understood  that GIH will have no assets at the time of sale
of the GIH stock other than shares of American  Maize.  Consummation  of the GIH
Stock Purchase Agreement will be conditioned on (A) the approval by the Board of
Directors of American Maize and the stockholders of American Maize of the Merger
Agreement and of an amendment to the Articles of Incorporation of American Maize
(each as  described in paragraph  (ii)  below),  (B) the  agreement of the other
stockholders of GIH to the sale of GIH common stock and (C) subject to paragraph
(iv) below,  the receipt by Swisher (as defined below) of assurances  reasonably
satisfactory to the Purchasers (as defined below) of the  availability of senior
debt in the aggregate  amount of $110 million on commercially  reasonable  terms
and  conditions.  Consummation  of the GIH Stock  Purchase  Agreement will occur
immediately prior to consummation of the Merger Agreement. You will agree in the
GIH Stock  Purchase  Agreement  not to sell your  shares of GIH or permit GIH to
sell its American  Maize shares to any other party at any time prior to December
31, 1995. The GIH

Stock Purchase Agreement also will contain other customary terms and conditons;

         (ii) EBS and a subsidiary of Subsidiary I ("Subsidiary  II") will enter
into an  agreement  and plan of merger  with  American  Maize  pursuant to which
Subsidiary  II will be  merged  with and  into  American  Maize  and each of the
outstanding  shares of common  stock of  American  Maize  (other than the shares
owned  by GIH)  will be  cancelled  in  exchange  for $40 in cash  (the  "Merger
Agreement"). The Merger Agreement will contain substantially equivalent terms as
contained in the  Agreement  and Plan of Merger,  dated as of February 22, 1995,
among  American  Maize,  EBS and Cerestar USA, Inc.  Consummation  of the Merger
Agreement will be  conditioned,  among other  customary  conditions,  on (A) the
approval of the Merger  Agreement by the requisite vote under the Maine Business
Corporation Act ("MBCA") of the stockholders of American Maize, (B) no more than
5% of the  holders of common  stock of  American  Maize  perfecting  dissenters'
rights  under Maine law by filing a written  objection to the merger prior to or
during the meeting of stockholders to vote upon the Merger Agreement and (C) the
approval of the Board of  Directors  and  stockholders  of American  Maize of an
amendment to the Articles of  Incorporation of American Maize making Section 910
of the MBCA inapplicable to American Maize;

         (iii) EBS and Subsidiary I will enter into a stock  purchase  agreement
with  you  or  your   respective   nominees  who  are  controlled  by  you  (the
"Purchasers")  pursuant to which they will agree to cause American Maize to sell
88% of the  outstanding  shares of common stock of Swisher  International,  Inc.
("Swisher") to the  Purchasers for $145 million in cash and a subordinated  note
(the  "Note")  issued by  Swisher in the  principal  amount of $20  million  (as
described in paragraph (iv) below) (the "Swisher Stock Purchase Agreement"). The
sale of the common  stock of Swisher will effect a transfer of all of the assets
and liabilities (excluding intercompany  liabilities) related to the business of
Swisher (subject to the agreement of the parties on the closing balance sheet of
Swisher),  provided,  however, that Swisher will have only $5 million of cash on
hand at the  time of  consummation  of the  sale.  The  Swisher  Stock  Purchase
Agreement  will  provide  that Swisher  will  indemnify  American  Maize and its
affiliates  for all past,  present  and  future  liabilities  arising  out of or
related to the business or operations of Swisher;

         (iv) The Note issued by Swisher will pay interest at the rate of 6% per
annum,  payable  semi-annually in arrears. The Note will provide for the payment
of $3 million of the principal amount of the Note on each of the fifth and sixth
anniversaries  of the date of issuance of the Note and payment of $14 million of
the  principal  amount  of the Note on the  seventh  anniversary  of the date of
issuance of the Note. The indebtedness evidenced by the Note will be subordinate
and junior to no more than $110  million of senior debt  containing  terms which
are reasonably  satisfactory to EBS. The Note will contain other customary terms
and  conditions.  If the senior lenders  require a modification to the repayment
schedule for the Note set forth above, the

parties  hereto will use their best  efforts to negotiate in good faith to agree
on a repayment  schedule  and other terms of the Note that are in the  aggregate
economically  comparable to American  Maize to the repayment  schedule and other
terms of the Note contemplated herein; and

         (v)  Concurrent  with   consummation  of  the  Swisher  Stock  Purchase
Agreement and execution of the Note,  American Maize, the Purchasers and Swisher
will enter into a stockholders agreement (the "Swisher Stockholders Agreement").
The Swisher Stockholders  Agreement will entitle American Maize to (A) designate
one representative who will be entitled to (i) receive notice of, (ii) attend as
an observer  and (iii)  receive  copies of all  documents  distributed  at, each
meeting  of  the  Board  of  Directors  of  Swisher,  (B)  exercise  "piggyback"
registration  rights in the event of an initial  public  offering  of the common
stock of Swisher,  (C)  exercise  first  priority  tag-along  rights to sell its
shares of Swisher  common stock in the event of the sale of any shares of common
stock by another  stockholder of Swisher,  (D) at its option require Swisher and
the stockholders of Swisher to purchase  American Maize's shares of common stock
of  Swisher  at a price  equal  to the fair  market  value  of such  shares  (as
determined  by  one  or  more  investment  banks  reasonably  acceptable  to the
Puchasers and EBS based on the acquisition value of Swisher at that time) at any
time  after  the  fifth  anniversary  of the  date of the  Swisher  Stockholders
Agreement  and (E)  receive  information  on a  periodic  basis  related  to the
operations and financial results of Swisher. The Swisher Stockholders  Agreement
also will entitle Swisher at its option to purchase  American  Maize's shares of
common stock of Swisher at a price equal to the fair market value of such shares
(as  determined by one or more  investment  banks  reasonably  acceptable to the
Purchasers  and EBS based on the  acquisition  value of Swisher at that time) at
any time after the fifth  anniversary  of the date of the  Swisher  Stockholders
Agreement.  The Purchasers and EBS will each bear one-half of the aggregate fees
of any  investment  bank or banks  engaged to determine the fair market value of
shares of common stock of Swisher.

         The GIH Stock Purchase  Agreement,  the Merger  Agreement,  the Swisher
Stock Purchase Agreement,  the Note and the Swisher  Stockholders  Agreement are
hereinafter  referred  to  collectively  as  the  "Definitive   Agreements."  In
connection  with the  foregoing  and to induce all  parties  to work  toward the
negotiation and execution of Definitive Agreements with respect to such Proposed
Transactions, the parties hereto agree as follows:

         The parties shall use their best efforts to negotiate and enter into as
promptly as practicable  the Definitive  Agreements with respect to the Proposed
Transactions  embodying  the  terms  set  forth  herein  and such  other  terms,
agreements,   representations,   warranties   and  conditions  as  are  mutually
satisfactory  to  the  parties.  In  connection  with  the  preparation  of  the
Definitive  Agreements,  you shall provide EBS with such information  concerning
GIH as may reasonably be requested by EBS.

         It is understood  that this letter  agreement sets forth a statement of
intentions with respect to the Proposed  Transactions,  but does not contain all
matters  upon  which  agreement  must be  reached  in  order  for  the  Proposed
Transactions  to be  consummated.  It is  further  understood  that this  letter
agreement  constitutes  an  obligation  binding  on each  party  to use its best
efforts and to act in good faith to complete  the Proposed  Transactions  and to
negotiate and enter into the  Definitive  Agreements.  Other than the foregoing,
neither the Purchasers nor EBS will have any liability to the other.  Each party
will bear its own expenses that arise from this letter agreement.

         This letter agreement,  unless the parties mutually agree in writing to
extend it, will expire on the 45th day after the date hereof.

         This Agreement may be executed in any number of counterparts, each such
counterpart being deemed to be an original instrument, and all such counterparts
shall together constitute the same agreement.



         Please confirm that the foregoing  accurately  sets forth our agreement
by executing this letter and returning it to EBS.

July 7, 1995

                                                 Very truly yours,
                                                 ERIDANIA BEGHIN-SAY, S.A.
