                                  ----------
                       
  The issue price of each Structured Yield Product Exchangeable for Stock SM,
   % STRYPES SM Due       , 2001 (each, a "STRYPES") of Merrill Lynch & Co.,
Inc. (the "Company") being offered hereby is $     , which amount is equal to
the last sale price of the common stock, par value $1.00 per share (the "IMC
Common Stock" ), of IMC Global Inc., a Delaware corporation ("IMC"), on       ,
1996, as reported on the New York Stock Exchange (the "Initial Price"). The
STRYPES will mature on       , 2001 (the "Maturity Date"). Interest on the
STRYPES, at the rate of   % of the issue price per annum, is payable in cash
quarterly in arrears on           ,            ,          and           ,
beginning       , 1996. The STRYPES are not subject to redemption or any
sinking fund. The STRYPES will be unsecured obligations of the Company ranking
pari passu with all of its other unsecured and unsubordinated indebtedness. In
addition, the STRYPES will not restrict the Company's ability to incur
additional indebtedness ranking senior to, or pari passu with, the STRYPES. See
"Supplemental Description of the STRYPES--Ranking."
   
  On the Maturity Date, the Company will pay and discharge each STRYPES by
delivering to the holder thereof a percentage of each type of Reference
Property (subject to the Company's right to deliver, with respect to all, but
not less than all, Reference Property deliverable on the Maturity Date, cash
with an equal value) determined in accordance with the following formula: (a)
if the Reference Property Value (as defined herein) is greater than or equal to
$    (the "Threshold Appreciation Price"),   % of each type of Reference
Property, (b) if the Reference Property Value is less than the Threshold
Appreciation Price but is greater than $    (the "Initial Price"), a percentage
of each type of Reference Property, allocated as proportionately as
practicable, so that the aggregate value thereof is equal to the Initial Price
and (c) if the Reference Property Value is less than or equal to the Initial
Price, 100% of each type of Reference Property. The term "Reference Property"
shall mean initially one share of IMC Common Stock and shall be subject to
adjustment from time to time prior to the Maturity Date to reflect the addition
or substitution of any cash, securities and/or other property resulting from
the application of the adjustment provisions described herein. AS DESCRIBED
HEREIN, THE REFERENCE PROPERTY VALUE WILL REPRESENT A DETERMINATION OF THE
VALUE OF THE REFERENCE PROPERTY IMMEDIATELY PRIOR TO THE MATURITY DATE.
ACCORDINGLY, THERE CAN BE NO ASSURANCE THAT THE AMOUNT RECEIVABLE BY HOLDERS OF
THE STRYPES ON THE MATURITY DATE WILL BE EQUAL TO OR GREATER THAN THE ISSUE
PRICE OF THE STRYPES. IF THE REFERENCE PROPERTY VALUE IS LESS THAN THE INITIAL
PRICE, SUCH AMOUNT RECEIVABLE ON THE MATURITY DATE WILL BE LESS THAN THE ISSUE
PRICE PAID FOR THE STRYPES, IN WHICH CASE AN INVESTMENT IN THE STRYPES WILL
RESULT IN A LOSS. See "Supplemental Description of the STRYPES."     
  Reference is made to the accompanying prospectus of IMC covering the shares
of IMC Common Stock (including the preferred stock purchase rights associated
therewith) which may be received by a holder of the STRYPES on the Maturity
Date. IMC is not affiliated with the Company, will not receive any of the
proceeds from the sale of the STRYPES and will have no obligations with respect
to the STRYPES.
  SEE "RISK FACTORS" BEGINNING ON PAGE S-8 OF THIS PROSPECTUS SUPPLEMENT FOR
CERTAIN CONSIDERATIONS RELEVANT TO AN INVESTMENT IN THE STRYPES.
  For a discussion of certain United States Federal income tax consequences for
holders of the STRYPES, see "Certain United States Federal Income Tax
Considerations."
   
  The IMC Common Stock is listed on the New York Stock Exchange ("NYSE") under
the symbol "IGL." The STRYPES have been approved for listing on the NYSE,
subject to official notice of issuance.     
                                  ----------
THESE SECURITIES  HAVE NOT BEEN APPROVED  OR DISAPPROVED BY  THE SECURITIES AND

                                    SUMMARY
   
  The following summary is qualified in its entirety by the information
included and incorporated by reference in the accompanying Prospectus (the
"ML&Co. Prospectus") and by the more detailed information included elsewhere in
this Prospectus Supplement. Unless otherwise indicated, the information
contained in this Prospectus Supplement assumes that the Underwriter's over-
allotment option is not exercised. Unless the context otherwise requires, the
following summary assumes that on the Maturity Date the Reference Property
consists only of shares of IMC Common Stock (including the preferred stock
purchase rights associated therewith).     
 
                           MERRILL LYNCH & CO., INC.

PAYMENT AT MATURITY.........    
                             On the Maturity Date, the Company will pay and
                             discharge each STRYPES by delivering to the holder
                             thereof a percentage of each type of Reference
                             Property (subject to the Company's right to
                             deliver, with respect to all, but not less than
                             all, Reference Property deliverable on the
                             Maturity Date, cash with an equal value)
                             determined in accordance with the following
                             formula: (a) if the Reference Property Value (as
                             defined herein) is greater than or equal to $
                             (the "Threshold Appreciation Price"),    % of each
                             type of Reference Property, (b) if the Reference
                             Property Value is less than the Threshold
                             Appreciation Price but is greater than $   (the
                             "Initial Price"), a percentage of each type of
                             Reference Property, allocated as proportionately
                             as practicable, so that the aggregate value
                             thereof is equal to the Initial Price and (c) if
                             the Reference Property Value is less than or equal
                             to the Initial Price, 100% of each type of
                             Reference Property. The term "Reference Property"
                             shall mean initially one share of IMC Common Stock
                             and shall be subject to adjustment from time to
                             time prior to the Maturity Date to reflect the
                             addition or substitution of any cash, securities
                             and/or other property resulting from the
                             application of the adjustment provisions described
                             herein. AS DESCRIBED HEREIN, THE REFERENCE
                             PROPERTY VALUE WILL REPRESENT A DETERMINATION OF
                             THE VALUE OF THE REFERENCE PROPERTY IMMEDIATELY
                             PRIOR TO THE MATURITY DATE. ACCORDINGLY, THERE CAN
                             BE NO ASSURANCE THAT THE AMOUNT RECEIVABLE BY
                             HOLDERS OF THE STRYPES ON THE MATURITY DATE WILL
                             BE EQUAL TO OR GREATER THAN THE ISSUE PRICE OF THE
                             STRYPES. IF THE REFERENCE PROPERTY VALUE IS LESS
                             THAN THE INITIAL PRICE, SUCH AMOUNT RECEIVABLE ON
                             THE MATURITY DATE WILL BE LESS THAN THE ISSUE
                             PRICE PAID FOR THE STRYPES, IN WHICH CASE AN
                             INVESTMENT IN THE STRYPES WILL RESULT IN A LOSS.
                             See "Supplemental Description of the STRYPES--
                             General."     
 
NO REDEMPTION, SINKING FUND
 OR PAYMENT PRIOR TO
 MATURITY...................
                             The STRYPES are not subject to redemption by the
                             Company prior to the Maturity Date and do not
                             contain any sinking fund or other mandatory
                             redemption provisions. The STRYPES are not subject
                             to payment prior to the Maturity Date at the
                             option of the holder.
 
RANKING..................... The STRYPES will be unsecured obligations of the
                             Company ranking pari passu with all of its other
                             unsecured and unsubordinated indebtedness. See
                             "Supplemental Description of the STRYPES--Ranking"
                             herein and "Description of the STRYPES--Ranking"
                             in the ML&Co. Prospectus.
 
RELATIONSHIP TO IMC COMMON
 STOCK......................
                             The STRYPES will bear interest at    % of the
                             issue price per annum, a yield substantially in
                             excess of the    % dividend yield of IMC Common
                             Stock based on the last sale price of the IMC
                             Common Stock on       , 1996, as reported on the
                             NYSE, and the recent $.08 per share quarterly
                             dividend paid on the IMC Common Stock. However,
                             the opportunity for equity appreciation
 
                                      S-4

                             afforded by an investment in the STRYPES is less
                             than the opportunity for equity appreciation
                             afforded by a direct investment in the IMC Common
                             Stock because the amount receivable by a holder of
                             a STRYPES on the Maturity Date will only exceed
                             the issue price of such STRYPES if the Reference
                             Property Value exceeds the Threshold Appreciation
                             Price (which represents an appreciation of    %
                             over the Initial Price). Moreover, holders of the
                             STRYPES will only be entitled to receive on the
                             Maturity Date     % (the percentage equal to the
                             Initial Price divided by the Threshold
                             Appreciation Price) of any appreciation of the
                             value of Reference Property in excess of the
                             Threshold Appreciation Price. Holders of the
                             STRYPES will not be entitled to any rights with
                             respect to the Reference Property (including,
                             without limitation, voting rights and rights to
                             receive any dividends, interest or other
                             distributions in respect thereof) unless and until
                             such time, if any, as the Company shall have
                             delivered the Reference Property for STRYPES on
                             the Maturity Date, and unless the applicable
                             record date, if any, for the exercise of such
                             rights occurs after such delivery. See "Risk
                             Factors--Limitations on Opportunity for Equity
                             Appreciation" and "--No Stockholder's Rights."
                                 
TRADING PRICES.............. The trading prices of the STRYPES in the secondary
                             market will be directly affected by the trading
                             prices of the IMC Common Stock in the secondary
                             market. It is impossible to predict whether the
                             price of IMC Common Stock will rise or fall. In
                             addition, any market that develops for the STRYPES
                             is likely to influence the market for IMC Common
                             Stock. For example, the price of IMC Common Stock
                             could be depressed by investors' anticipation of
                             the potential distribution into the market of
                             substantial amounts of IMC Common Stock on the
                             Maturity Date, by possible sales of IMC Common
                             Stock by investors who view the STRYPES as a more
                             attractive means of equity participation in IMC,
                             and by hedging or arbitrage trading activity that
                             may develop involving the STRYPES and the IMC
                             Common Stock. See "Risk Factors--Factors Affecting
                             Trading Prices" and "--Impact of the STRYPES on
                             the Market for IMC Common Stock."
 
DILUTION....................    
                             The Reference Property (or the amount of cash)
                             that holders of the STRYPES are entitled to
                             receive upon payment and discharge on the Maturity
                             Date will not be adjusted for certain events, such
                             as offerings of IMC Common Stock for cash or in
                             connection with acquisitions. IMC is not
                             restricted from issuing additional IMC Common
                             Stock during the term of the STRYPES and has no
                             obligation to consider the interests of holders of
                             STRYPES for any reason. Additional issuances of
                             shares of IMC Common Stock may materially and
                             adversely affect the price of IMC Common Stock
                             and, because of the relationship of the percentage
                             of the Reference Property (or cash amount) to be
                             received upon payment and

                             such other events may adversely affect the trading
                             price of the STRYPES. See "Risk Factors--Dilution

PURCHASE AGREEMENT WITH
 GVI HOLDINGS, INC.....     
                                
                             Pursuant to an agreement (the "Purchase
                             Agreement") among the Company, Merrill Lynch
                             Mortgage Capital Inc., a wholly owned subsidiary
                             of the Company (the "ML&Co. Subsidiary"), and GVI
                             Holdings, Inc. ("GVI"), a wholly-owned subsidiary
                             of Great American Management and Investment, Inc.,
                             GVI is obligated to deliver to the ML&Co.
                             Subsidiary immediately prior to the Maturity Date
                             the Reference Property required by the Company to
                             pay and discharge all of the STRYPES (including
                             any STRYPES issued pursuant to the over-allotment
                             option granted by the Company to the Underwriter).
                             In lieu of delivering the Reference Property
                             immediately prior to the Maturity Date, GVI has
                             the right to satisfy its obligation under the
                             Purchase Agreement by delivering at such time cash
                             in an amount equal to the value of such Reference
                             Property immediately prior to the Maturity Date.
                             Such right, if exercised by GVI, must be exercised
                             with respect to all of the Reference Property
                             deliverable pursuant to the Purchase Agreement.
                             Under the Purchase Agreement, the Company has
                             agreed to pay and discharge the STRYPES by
                             delivering to the holders thereof on the Maturity
                             Date the form of consideration that the ML&Co.
                             Subsidiary receives from GVI. The consideration to
                             be paid by the ML&Co. Subsidiary under the
                             Purchase Agreement is $    in the aggregate, and
                             is payable to GVI on or about      , 1996. No
                             other consideration is payable by the ML&Co.
                             Subsidiary to GVI in connection with its
                             acquisition of the Reference Property pursuant to
                             the Purchase Agreement or the performance of the
                             Purchase Agreement by GVI.     
                                
                             GVI has no obligations with respect to the STRYPES
                             or amounts to be paid to holders thereof,
                             including any obligation to take the needs of the
                             Company or of holders of the STRYPES into
                             consideration in determining whether to deliver
                             the Reference Property or cash or for any other
                             reason. The Purchase Agreement among the Company,
                             the ML&Co. Subsidiary and GVI is a commercial
                             transaction and does not create any rights in, or
                             for the benefit of, any holder of STRYPES. See
                             "Certain Arrangements with GVI."     
 
CERTAIN UNITED STATES
FEDERAL  INCOME TAX
CONSIDERATIONS.............. Prospective investors in the STRYPES should be
                             aware that there exists uncertainty concerning the
                             proper United States Federal income tax
                             characterization and treatment of the STRYPES.
                             Accordingly, prospective investors should consider
                             the tax consequences of investing in the STRYPES.
                             See "Risk Factors--Tax Matters" and "Certain
                             United States Federal Income Tax Considerations."

GLOBAL NOTES................ Upon issuance, all STRYPES will be represented by
                             one or more global securities deposited with, and
                             registered in the name of, The Depository Trust
                             Company, as Securities Depository (the "Securities
                             Depository"), or a nominee thereof. As a result,
                             the Securities Depository, or its nominee, will be
                             considered the sole owner of the STRYPES under the
                             Indenture (as defined herein). Ownership interests
                             of actual purchasers of STRYPES will be recorded
                             on the records of participants in the Securities
                             Depository. See "Description of the STRYPES--
                             Securities Depository" in the ML&Co. Prospectus.
 
USE OF PROCEEDS.............    
                             The net proceeds to the Company from the sale of
                             the STRYPES are expected to be $    , $     of
                             which will be used to purchase an obligation of
                             the ML&Co. Subsidiary and the remainder of which
                             will be used for general corporate purposes. The
                             ML&Co. Subsidiary will use a portion of the
                             consideration that it receives from the Company to
                             pay to GVI the consideration due under the
                             Purchase Agreement.

                                  RISK FACTORS
   
  Prospective purchasers should read carefully this entire Prospectus
Supplement and the ML&Co. Prospectus and should consider, among other things,
the factors set forth below and under "Risk Factors" in the IMC Prospectus.
Unless the context otherwise requires, the following discussion assumes that on
the Maturity Date the Reference Property consists only of shares of IMC Common
Stock (including the preferred stock purchase rights associated therewith).
    
COMPARISON TO OTHER DEBT SECURITIES; RELATIONSHIP TO IMC COMMON STOCK
   
  The terms of the STRYPES differ from those of ordinary debt securities in
that the value of the Reference Property (or, pursuant to the option of the
Company, the amount of cash) that a holder of a STRYPES will receive on the
Maturity Date is not fixed, but is based on the Reference Property Value (see
"Supplemental Description of the STRYPES"). THERE CAN BE NO ASSURANCE THAT SUCH
AMOUNT RECEIVABLE BY THE HOLDER ON THE MATURITY DATE WILL BE EQUAL TO OR
GREATER THAN THE ISSUE PRICE OF THE STRYPES. IF THE REFERENCE PROPERTY VALUE IS
LESS THAN THE INITIAL PRICE, SUCH AMOUNT RECEIVABLE ON THE MATURITY DATE WILL
BE LESS THAN THE ISSUE PRICE PAID FOR THE STRYPES, IN WHICH CASE AN INVESTMENT
IN STRYPES WILL RESULT IN A LOSS. ACCORDINGLY, A HOLDER OF STRYPES ASSUMES THE
RISK THAT THE MARKET VALUE OF THE REFERENCE PROPERTY MAY DECLINE, AND THAT SUCH
DECLINE COULD BE SUBSTANTIAL. THE IMC PROSPECTUS COVERS THE SHARES OF IMC
COMMON STOCK (INCLUDING THE PREFERRED STOCK PURCHASE RIGHTS ASSOCIATED
THEREWITH) WHICH MAY BE RECEIVED BY A HOLDER OF THE STRYPES ON THE MATURITY
DATE.     
 
LIMITATION ON OPPORTUNITY FOR EQUITY APPRECIATION
   
  The opportunity for equity appreciation afforded by an investment in the
STRYPES is less than the opportunity for equity appreciation afforded by a
direct investment in the IMC Common Stock because the amount receivable by a
holder of a STRYPES on the Maturity Date will only exceed the issue price of
such STRYPES if the Reference Property Value exceeds the Threshold Appreciation
Price (which represents an appreciation of    % over the Initial Price).
Moreover, holders of the STRYPES will only be entitled to receive on the
Maturity Date    % (the percentage equal to the Initial Price divided by the
Threshold Appreciation Price) of any appreciation of the value of the Reference
Property in excess of the Threshold Appreciation Price. See "Supplemental
Description of the STRYPES." Because the price of the Reference Property is
subject to market fluctuations, the value of the Reference Property (or,
pursuant to the option of the Company, the amount of cash) received by a holder
of a STRYPES on the Maturity Date, determined as described herein, may be more
or less than the issue price of the STRYPES.     
 
FACTORS AFFECTING TRADING PRICES
 
  The trading prices of the STRYPES in the secondary market will be directly
affected by the trading prices of the IMC Common Stock in the secondary market.
It is impossible to predict whether the price of IMC Common Stock will rise or
fall. Trading prices of IMC Common Stock will be influenced by IMC's operating
results and prospects, by complex and interrelated political, economic,
financial and other factors and market conditions that can affect the capital
markets generally, the market segment of which IMC is a part, the NYSE (on
which the IMC Common Stock is traded), including the level of, and fluctuations
in, the trading prices of stocks generally and sales of substantial amounts of
IMC Common Stock in the market subsequent to the offering of the STRYPES or the
perception that such sales could occur, and by other events that are difficult
to predict and are beyond the Company's control.
 
IMPACT OF STRYPES ON THE MARKET FOR IMC COMMON STOCK
 
  It is not possible to predict accurately how or whether the STRYPES will
trade in the secondary market or whether such market will be liquid. Any market
that develops for the STRYPES is likely to influence and be influenced by the
market for IMC Common Stock. For example, the price of IMC Common Stock could
become more volatile and could be depressed by investors' anticipation of the
potential distribution into the market of substantial amounts of IMC Common
Stock on the Maturity Date, by possible sales of IMC Common Stock by investors
who view the STRYPES as a more attractive means of equity participation in IMC,
and by hedging or arbitrage trading activity that may develop involving the
STRYPES and the IMC
 
                                      S-8

Common Stock. In addition, if the Underwriter's over-allotment option is not
exercised in full, GVI will continue to own shares of the IMC Common Stock that
are not subject to the Purchase Agreement. GVI is not precluded from selling
any such shares of IMC Common Stock, either pursuant to Rule 144 under the
Securities Act of 1933, as amended (the "Securities Act"), or by exercising its
registration rights. Any such sales could have an adverse effect on the market
price of IMC Common Stock and/or the STRYPES and could affect the percentage of
the Reference Property (or cash amount) that a holder of a STRYPES will receive
on the Maturity Date.     
 
POSSIBLE ILLIQUIDITY OF THE SECONDARY MARKET
   
  It is not possible to predict how the STRYPES will trade in the secondary
market or whether such market will be liquid or illiquid. The STRYPES are novel
securities and there is currently no secondary market for the STRYPES. The
STRYPES have been approved for listing on the NYSE, subject to official notice
of issuance. However there can be no assurance that an active trading market
for the STRYPES will develop, that such listing will provide the holders of the
STRYPES with liquidity of investment, or that the STRYPES will not later be
delisted or that trading of the STRYPES on the NYSE will not be suspended. In
the event of a delisting or suspension of trading on the NYSE, the Company will
apply for listing of the STRYPES on another national securities exchange or for
quotation on another trading market. If the STRYPES are not listed or traded on
any securities exchange or trading market, or if trading of the STRYPES is
suspended, pricing information for the STRYPES may be more difficult to obtain
and the liquidity of the STRYPES may be adversely affected.     
 
NO STOCKHOLDER'S RIGHTS
   
  Holders of the STRYPES will not be entitled to any rights with respect to the
Reference Property (including, without limitation, voting rights and rights to
receive any dividends, interest or other distributions in respect thereof)
unless and until such time, if any, as the Company shall have delivered the
Reference Property for STRYPES on the Maturity Date, and unless the applicable
record date, if any, for the exercise of such rights occurs after such
delivery. For example, in the event that an amendment is proposed to the
Restated Certificate of Incorporation of IMC and the record date for
determining the stockholders of record entitled to vote on such amendment
occurs prior to such delivery, holders of the STRYPES will not be entitled to
vote on such amendment.     
 
NO AFFILIATION BETWEEN THE COMPANY AND IMC
 
  The Company has no affiliation with IMC, and IMC has no obligations with
respect to the STRYPES or amounts to be paid to holders thereof, including any
obligation to take the needs of the Company or of holders of the STRYPES into
consideration for any reason. IMC will not receive any of the proceeds of the
offering of the STRYPES made hereby and is not responsible for, and has not
participated in, the determination of the timing of, prices for or quantities
of the STRYPES to be issued, or the determination or calculation of the amount
receivable by holders of the STRYPES on the Maturity Date. IMC is not involved
with the administration or trading of the STRYPES and has no obligations with
respect to the amount receivable by holders of the STRYPES on the Maturity
Date.
 
DILUTION OF IMC COMMON STOCK
   
  The Reference Property (or, pursuant to the option of the Company, the amount
of cash) that holders of the STRYPES are entitled to receive on the Maturity
Date is subject to adjustment for certain events arising from, among others, a
merger or consolidation in which IMC is not the surviving or resulting
corporation and the liquidation, dissolution, winding up or bankruptcy of IMC,
as well as stock splits and combinations, stock dividends and certain other
actions of IMC that modify its capital structure. See "Supplemental Description
of the STRYPES--Reference Property Adjustments." Such Reference Property (or
cash amount) to be received by such holders on the Maturity Date will not be
adjusted for other events,     
 
                                      S-9
<PAGE>
 
   
such as offerings of IMC Common Stock for cash or in connection with
acquisitions. IMC is not restricted from issuing additional shares of IMC
Common Stock during the term of the STRYPES and has no obligation to consider
the interests of the holders of the STRYPES for any reason. Additional
issuances may materially and adversely affect the price of the IMC Common Stock
and, because of the relationship of the percentage of the Reference Property
(or cash amount) to be received on the Maturity Date to the price of the IMC
Common Stock, such other events may adversely affect the trading price of the
STRYPES.     
       
TAX MATTERS
   
  Because of an absence of authority as to the proper characterization of the
STRYPES, their ultimate tax treatment is uncertain. Accordingly, no assurances
can be given that any particular characterization and treatment of the STRYPES
will be accepted by the Internal Revenue Service ("IRS") or upheld by a court.
However, it is the opinion of Brown & Wood, counsel to the Company, that the
characterization and tax treatment of the STRYPES described herein (and
described in greater detail under "Certain United States Federal Income Tax
Considerations"), while not the only reasonable characterization and tax
treatment, is based on reasonable interpretations of law currently in effect
and, even if successfully challenged by the IRS, will not result in the
imposition of penalties. The Indenture will require that any holder subject to
U.S. Federal income tax include currently in income, for U.S. Federal income
tax purposes, payments denominated as interest that are made with respect to a
STRYPES in accordance with such holder's regular method of tax accounting. The
Indenture also requires the Company and holders to treat each STRYPES for tax
purposes as a unit (a "Unit") consisting of (i) a debt instrument (the "Debt
Instrument") with a fixed principal amount unconditionally payable on the
Maturity Date equal to the issue price of the STRYPES and bearing interest at
the stated interest rate on the STRYPES and (ii) a forward purchase contract
(the "Forward Contract") pursuant to which the holder agrees to use the
principal payment due on the Debt Instrument to purchase on the Maturity Date
the Reference Property which the Company is obligated under the STRYPES to
deliver at that time (subject to the Company's right to deliver cash in lieu of
the Reference Property). The Indenture also requires that upon the acquisition
of a STRYPES and upon a holder's sale or other disposition of a STRYPES prior
to the Maturity Date, the amount paid or realized by the holder be allocated by
the holder between the Debt Instrument and the Forward Contract based upon
their relative fair market values (as determined on the date of acquisition or
disposition). For these purposes, with respect to acquisitions of STRYPES in
connection with the original issuance thereof, the Company and each holder
agrees, pursuant to the terms of the Indenture, to allocate $        of the
entire initial purchase price of a STRYPES (i.e., the issue price of a STRYPES)
to the Debt Instrument and to allocate the remaining $        of the entire
initial purchase price of a STRYPES to the Forward Contract. As previously
mentioned, the appropriate character and timing of income, gain or loss to be
recognized on a STRYPES is uncertain and investors should consult their own tax
advisers concerning the application of the United States Federal income tax
laws to their particular situations as well as any consequences of the
purchase, ownership and disposition of the STRYPES arising under the laws of
any other taxing jurisdiction. The tax consequences of investing in the STRYPES
are described in greater detail under "Certain United States Federal Income Tax
Considerations."     
 
HOLDING COMPANY STRUCTURE
 
  Since the Company is a holding company, the right of the Company, and hence
the right of creditors of the Company (including the holders of the STRYPES),
to participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized. In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

(1)IMC declared a quarterly dividend of $0.08 per share on April 18, 1996,
   payable on June 28, 1996 to stockholders of record at the close of business
   on June 14, 1996.
   
  As of June 17, 1996, there were approximately 475 record holders of the IMC
Common Stock. On June 17, 1996, the last reported sale price of the IMC Common
Stock on the NYSE was $39.25 per share.     
 
  In April 1993, IMC's Board of Directors reduced cash dividend payments on the
IMC Common Stock in light of financial demands of litigation arising out of an
explosion at a nitroparaffins plant operated by IMC in Sterlington, Louisiana,
and weakness in concentrated phosphate prices. Although IMC has paid cash
dividends in recent quarters, any future payment of cash dividends is subject
to the discretion of IMC's Board of Directors and will be dependent on IMC's
results of operations, financial condition, cash requirements and other
relevant factors. Since substantially all of IMC's operations are conducted
through subsidiaries, IMC cash flow, and consequently its future ability to pay
dividends, will be dependent upon the earnings of its subsidiaries and the
payment of funds by those subsidiaries to IMC in the form of loans, dividends
or otherwise. Certain of IMC's debt agreements contain restrictions on the
payment of dividends by IMC's subsidiaries.
   
  The Company makes no representation as to the amount of dividends, if any,
that IMC will pay in the future. In any event, holders of STRYPES will not be
entitled to receive any dividends or interest that may be payable on IMC Common
Stock or other Reference Property until such time as the Company, if it so
elects, delivers the Reference Property on the Maturity Date of the STRYPES,
and then only with respect to dividends having a record date on or after the
date of delivery thereof. See "Supplemental Description of the STRYPES."     
 
                          SUPPLEMENTAL USE OF PROCEEDS
   
  The net proceeds to the Company from the sale of the STRYPES are expected to
be $    , $     of which will be used to purchase an obligation of the ML&Co.
Subsidiary and the remainder of which will be used for general corporate
purposes. The ML&Co. Subsidiary will use a portion of the consideration that it
receives from the Company to pay to GVI the consideration due under the
Purchase Agreement.

                    SUPPLEMENTAL DESCRIPTION OF THE STRYPES
 
  The STRYPES are a series of Senior Debt Securities to be issued under an
indenture, dated as of April 1, 1983 and restated as of April 1, 1987, as
amended and supplemented as of   , 1996 (the indenture dated as of April 1,
1983 and restated as of April 1, 1987, as amended and supplemented from time to
time, the "Indenture") between the Company and Chemical Bank (successor by
merger to Manufacturers Hanover Trust Company), as trustee (the "Trustee").
Certain provisions of the Indenture are summarized in the ML&Co. Prospectus.
All capitalized terms not otherwise defined herein have the meanings specified
in the Indenture.
 
GENERAL
 
  The aggregate number of STRYPES to be issued under the Indenture will be
limited to 5,661,119, plus such additional number of STRYPES as may be issued
pursuant to the over-allotment option granted by the Company to the
Underwriter. See "Underwriting." No fractional STRYPES will be issued.
   
  Each STRYPES, which will be issued at a price of $    , will bear interest at
the rate of  % of the issue price per annum (or $   per annum) from     , 1996,
or from the most recent Interest Payment Date to which interest has been paid
or provided for, until the Maturity Date or such earlier date on which such
STRYPES is repaid pursuant to the terms thereof. Interest on the STRYPES will
be payable in cash quarterly in arrears on      ,       ,     and      ,
beginning      , 1996, and on the Maturity Date (each, an "Interest Payment
Date"), to the persons in whose names the STRYPES are registered at the close
of business on the fifteenth calendar day (whether or not a Business Day)
immediately preceding such Interest Payment Date. Interest on the STRYPES will
be computed on the basis of a 360-day year of twelve 30-day months. If an
Interest Payment Date falls on a day that is not a Business Day, the interest
payment to be made on such Interest Payment Date will be made on the next
succeeding Business Day with the same force and effect as if made on such
Interest Payment Date, and no additional interest will accrue as a result of
such delayed payment.     
   
  The STRYPES will mature on      , 2001. On the Maturity Date, the Company
will pay and discharge each STRYPES by delivering to the holder thereof a
percentage of each type of Reference Property (subject to the Company's right
to deliver, with respect to all, but not less than all, Reference Property
deliverable on the Maturity Date, cash with an equal value) determined in
accordance with the following formula: (a) if the Reference Property Value (as
defined below) is greater than or equal to the Threshold Appreciation Price,
  % of each type of Reference Property, (b) if the Reference Property Value is
less than the Threshold Appreciation Price but is greater than the Initial
Price, a percentage of each type of Reference Property, allocated as
proportionately as practicable, so that the aggregate value thereof is equal to
the Initial Price and (c) if the Reference Property Value is less than or equal
to the Initial Price, 100% of each type of Reference Property. ACCORDINGLY,
THERE CAN BE NO ASSURANCE THAT THE AMOUNT RECEIVABLE BY HOLDERS OF THE STRYPES
ON THE MATURITY DATE WILL BE EQUAL TO OR GREATER THAN THE ISSUE PRICE OF THE
STRYPES. IF THE REFERENCE PROPERTY VALUE IS LESS THAN THE INITIAL PRICE, SUCH
AMOUNT RECEIVABLE ON THE MATURITY DATE WILL BE LESS THAN THE ISSUE PRICE PAID
FOR THE STRYPES, IN WHICH CASE AN INVESTMENT IN STRYPES WILL RESULT IN A LOSS.
       
  Notwithstanding the foregoing, the Company may, in lieu of delivering the
applicable percentage of each type of Reference Property, deliver cash in an
amount equal to the sum of (a) for any portion of the Reference Property
consisting of cash that is otherwise deliverable on the Maturity Date, the
amount of such cash, without interest thereon, (b) for any portion of the
Reference Property consisting of property other than cash or Reference
Securities that is otherwise deliverable on the Maturity Date, the fair market
value (as determined by a nationally recognized independent investment banking
firm retained for this purpose by the Company) as of the third Trading Day
preceding the Maturity Date of such property, and (c) for any portion of the
Reference Property consisting of a Reference Security (as defined below) that
is otherwise deliverable     
 
                                      S-13
<PAGE>
 
   
on the Maturity Date (except as described under "Reference Property
Adjustments" below), an amount equal to the average Closing Price (as defined
below) per unit of such Reference Security on the 20 Trading Days immediately
prior to, but not including, the second Trading Day preceding the Maturity Date
multiplied by the number of units of such Reference Security constituting part
of the Reference Property, subject to the Company's agreement contained in the
Purchase Agreement to deliver on the Maturity Date the form of consideration
that the ML&Co. Subsidiary receives from GVI. Such right, if exercised by the
Company, must be exercised with respect to all Reference Property otherwise
deliverable on the Maturity Date in payment of all outstanding STRYPES. On or
prior to the sixth Business Day prior to the Maturity Date, the Company will
notify The Depository Trust Company and the Trustee and publish a notice in The
Wall Street Journal or another daily newspaper of national circulation stating
whether the STRYPES will be paid and discharged by delivery of the applicable
percentage of each type of Reference Property or cash. At the time such notice
is published, the Reference Property Value will not have been determined. If
the Company elects to deliver Reference Property, holders of the STRYPES will
be responsible for the payment of any and all brokerage costs upon the
subsequent sale thereof.     
   
  The term "Reference Property" initially means one share of IMC Common Stock
and shall be subject to adjustment from time to time prior to the Maturity Date
to reflect the addition or substitution of any cash, securities and/or other
property resulting from the application of the adjustment provisions described
herein. See "--Reference Property Adjustments" below. The term "Reference
Security" means, at any time, any security (as defined in Section 2(1) of the
Securities Act) then constituting part of the Reference Property. The term
"Reference Property Value" means, subject to the adjustment provisions
described below, the sum of (a) for any portion of the Reference Property
consisting of cash, the amount of such cash, (b) for any portion of the
Reference Property consisting of property other than cash or Reference
Securities, the fair market value (as determined by a nationally recognized
independent investment banking firm retained for this purpose by the Company)
as of the third Trading Day preceding the Maturity Date of such property, and
(c) for any portion of the Reference Property consisting of a Reference
Security, an amount equal to the average Closing Price per unit of such
Reference Security on the 20 Trading Days immediately prior to, but not
including, the second Trading Day preceding the Maturity Date multiplied by the
number of units of such Reference Security constituting part of the Reference
Property. The "Closing Price" of any Reference Security on any date of
determination means the closing sale price (or, if no closing price is
reported, the last reported sale price) of such Reference Security on the NYSE
on such date or, if such Reference Security is not listed for trading on the
NYSE on any such date, as reported in the composite transactions for the
principal United States securities exchange on which such Reference Security is
so listed, or if such Reference Security is not so listed on a United States
national or regional securities exchange, as reported by the National
Association of Securities Dealers, Inc. Automated Quotation System, or, if such
Reference Security is not so reported, the last quoted bid price for such
Reference Security in the over-the-counter market as reported by the National
Quotation Bureau or similar organization, or, if such bid price is not
available, the market value of such Reference Security on such date as
determined by a nationally recognized independent investment banking firm
retained for this purpose by the Company. A "Trading Day" is defined as a day
on which the Reference Security the Closing Price of which is being determined
(A) is not suspended from trading on any national or regional securities
exchange or association or over-the-counter market at the close of business and
(B) has traded at least once on the national or regional securities exchange or
association or over-the-counter market that is the primary market for the
trading of such Reference Security.     
   
  For illustrative purposes only, the following table shows the number of
shares of IMC Common Stock or the amount of cash that a holder of STRYPES would
receive for each STRYPES at various Reference Property Values. The table
assumes that there will be no Reference Property adjustments as described below
and, accordingly, that on the Maturity Date the Reference Property will consist
of one share of IMC Common Stock. There can be no assurance that the Reference
Property Value will be within the range set forth below. Given the Initial
Price of $        and the Threshold Appreciation Price of $       , a STRYPES
holder would receive on the Maturity Date the following number of shares of IMC
Common Stock or amount of cash (if the Company elects to pay and discharge the
STRYPES with cash) per STRYPES:

REFERENCE PROPERTY ADJUSTMENTS     
   
  The Reference Property is subject to adjustment if an issuer of a Reference
Security shall: (i) subdivide or split the outstanding units of such Reference
Security into a greater number of units; (ii) combine the outstanding units of
such Reference Security into a smaller number of units; (iii) issue by
reclassification of units of such Reference Security any units of another
security of such issuer; (iv) issue rights or warrants to all holders of such
Reference Security entitling them, for a period expiring prior to the fifteenth
calendar day following the Maturity Date, to subscribe for or purchase any of
its securities or other property (other than rights to purchase units of such
Reference Security pursuant to a plan for the reinvestment of dividends or
interest); or (v) pay a dividend or make a distribution to all holders of such
Reference Security of cash, securities or other property (excluding any cash
dividend on any Reference Security consisting of capital stock that does not
constitute an Extraordinary Cash Dividend (as defined below), excluding any
payment of interest on any Reference Security consisting of an evidence of
indebtedness and excluding any dividend or distribution referred to in clause
(i), (ii), (iii) or (iv) above) or issue to all holders of such Reference
Security rights or warrants to subscribe for or purchase any of its securities
or other property (other than those referred to in clause (iv) above) (any of
the foregoing cash, securities or other property or rights or warrants are
referred to as the "Distributed Assets").     
   
  In the case of the events referred to in clauses (i), (ii) and (iii) above,
the Reference Property shall be adjusted to include the number of units of such
Reference Security and/or other security of such issuer which a holder of units
of such Reference Security would have owned or been entitled to receive
immediately following any such event had such holder held, immediately prior to
such event, the number of units of such Reference Security constituting part of
the Reference Property immediately prior to such event. Each such adjustment
shall become effective immediately after the effective date for such
subdivision, split, combination or reclassification, as the case may be. Each
such adjustment shall be made successively.     
   
  In the case of the event referred to in clause (iv) above, the Reference
Property shall be adjusted to include an amount in cash equal to the fair
market value (determined as described below), as of the fifth Business Day
(except as provided below) following the date on which such rights or warrants
are received by securityholders entitled thereto (the "Receipt Date"), of each
such right or warrant multiplied by the product of (A) the number of such
rights or warrants issued for each unit of such Reference Security and (B) the
number of units of such Reference Security constituting part of the Reference
Property on the date of issuance of such rights or warrants, immediately prior
to such issuance, without interest thereon. For purposes of the foregoing, the
fair market value of each such right or warrant shall be the quotient of (x)
the highest net bid, as of approximately 10:00 A.M., New York City time, on the
fifth Business Day following the Receipt Date for settlement three Business
Days later, by a recognized securities dealer in The City of New York selected
by or on behalf of the Company (from three (or such fewer number of dealers as
may be providing such bids) such recognized dealers selected by or on behalf of
the Company), for the purchase by such quoting dealer of the number of rights
or warrants (the "Aggregate Number") that a holder of such Reference Security
would receive if such holder held, as of the record date for determination of
stockholders entitled to receive such rights or warrants, a number of units of
such Reference Security equal to the product of (1) the aggregate number of
Outstanding STRYPES as of such record date and (2) the number of units of such
Reference Security constituting part of the Reference Property, divided by (y)
the Aggregate Number. Each such adjustment shall become effective on the fifth
Business Day following the Receipt Date of such rights or warrants. If for any
reason the Company is unable to obtain the required bid on the fifth Business
Day following the Receipt Date, it shall attempt to obtain such bid at
successive intervals of three months thereafter and on the third Trading Day
prior to the Maturity Date until it is able to obtain the required bid. From
the date of issuance of such rights or warrants until the required bid is
obtained, the Reference Property shall include the number of such rights or
warrants issued for each unit of such Reference Security multiplied     
 
                                      S-15
<PAGE>
 
   
by the number of units of such Reference Security constituting part of the
Reference Property on the date of issuance of such rights or warrants,
immediately prior to such issuance, and such rights or warrants constituting
part of the Reference Property shall be deemed for all purposes hereof to have
a fair market value of zero.     
   
  In the case of the event referred to in clause (v) above, the Reference
Property shall be adjusted to include, from and after such dividend,
distribution or issuance, (x) in respect of that portion, if any, of the
Distributed Assets consisting of cash, the amount of such Distributed Assets
consisting of cash received for each unit of such Reference Security multiplied
by the number of units of such Reference Security constituting part of the
Reference Property on the date of such dividend, distribution or issuance,
immediately prior to such dividend, distribution or issuance, without interest
thereon, plus (y) in respect of that portion, if any, of the Distributed Assets
which are other than cash, the number or amount of each type of Distributed
Assets other than cash received with respect to each unit of such Reference
Security multiplied by the number of units of such Reference Security
constituting part of the Reference Property on the date of such dividend,
distribution or issuance, immediately prior to such dividend, distribution or
issuance.     
          
  An "Extraordinary Cash Dividend" means, with respect to any consecutive 12-
month period, the amount, if any, by which the aggregate amount of all cash
dividends on any Reference Security consisting of capital stock occurring in
such 12-month period (or, if such Reference Security was not outstanding at the
commencement of such 12-month period, occurring in such shorter period during
which such Reference Security was outstanding) exceeds on a per share basis 12%
of the average of the Closing Prices per share of such Reference Security over
such 12-month period (or such shorter period during which such Reference
Security was outstanding); provided that, for purposes of the foregoing
definition, the amount of cash dividends paid on a per share basis will be
appropriately adjusted to reflect the occurrence during such period of any
stock dividend or distribution of shares of capital stock of the issuer of such
Reference Security or any subdivision, split, combination or reclassification
of shares of such Reference Security.     
          
  In the event of (A) any consolidation or merger of an issuer of a Reference
Security with or into another entity (other than a merger or consolidation in
which such issuer is the continuing corporation and in which the Reference
Security outstanding immediately prior to the merger or consolidation is not
exchanged for cash, securities or other property of such issuer or another
entity), (B) any statutory exchange of securities of an issuer of a Reference
Security with another entity (other than in connection with a merger or
acquisition) or (C) any liquidation, dissolution, winding up or bankruptcy of
an issuer of a Reference Security (excluding any distribution in such event
referred to in clause (v) above) (any such event described in clause (A), (B)
or (C), a "Reorganization Event"), the Reference Property shall be adjusted to
include, from and after the effective date for such Reorganization Event, in
lieu of the number of units of such Reference Security constituting part of the
Reference Property immediately prior to the effective date for such
Reorganization Event, the amount or number of any cash, securities and/or other
property owned or received in such Reorganization Event with respect to each
unit of such Reference Security multiplied by the number of units of such
Reference Security constituting part of the Reference Property immediately
prior to the effective date for such Reorganization Event.     
       
  No adjustments will be made for certain other events, such as offerings of
IMC Common Stock by IMC for cash or in connection with acquisitions. Likewise,
no adjustments will be made for any sales of IMC Common Stock by GVI.
   
  The Company is required, within ten Business Days following the occurrence of
an event that requires an adjustment to the Reference Property (or if the
Company is not aware of such occurrence, as soon as practicable after becoming
so aware), to provide written notice to the Trustee and to the holders of the
STRYPES of the occurrence of such event and a statement in reasonable detail
setting forth the amount or number of each type of Reference Security and other
property then constituting part of the Reference Property.

FRACTIONAL INTERESTS     
   
  No fractional units of any Reference Security will be delivered if the
Company pays and discharges the STRYPES by delivering Reference Property. In
lieu of any fractional unit otherwise deliverable in respect of all STRYPES of
any holder on the Maturity Date, such holder shall be entitled to receive an
amount in cash equal to the value of such fractional unit based on the average
Closing Price per unit of such Reference Security on the 20 Trading Days
immediately prior to, but not including, the second Trading Day preceding the
Maturity Date.     
   
  To the extent practicable, the Company will deliver fractional interests of
any Reference Property other than cash or a Reference Security if the Company
pays and discharges the STRYPES by delivering Reference Property. If such
delivery is not practicable, in lieu of delivering any such fractional interest
otherwise deliverable in respect of all STRYPES of any holder on the Maturity
Date, such holder shall be entitled to receive an amount in cash equal to the
value of such fractional interest based on the fair market value (as determined
by a nationally recognized independent investment banking firm retained for
this purpose by the Company) as of the third Trading Day preceding the Maturity
Date of such Reference Property other than cash or a Reference Security.     
 
REDEMPTION, SINKING FUND AND PAYMENT PRIOR TO MATURITY
 
  The STRYPES are not subject to redemption by the Company prior to the
Maturity Date and do not contain sinking fund or other mandatory redemption
provisions. The STRYPES are not subject to payment prior to the Maturity Date
at the option of the holder.
 
RANKING
 
  The STRYPES will be unsecured obligations and will rank pari passu with all
other unsecured and unsubordinated indebtedness of the Company. At March 29,
1996, the Company had long-term borrowings outstanding of $20,226 million. In
addition, at March 29, 1996, there were $526 million of bank loans and $17,222
million of commercial paper outstanding.
 
  The Company had no secured debt at March 29, 1996. At such date,
collateralized financing transactions of the Company's subsidiaries consisted
of $3,768 million of cash deposits for securities loaned and $61,657 million of
securities sold under agreements to repurchase. See Note 4 to "Summary
Financial Information" in the ML&Co. Prospectus.
 
  There are no contractual restrictions on the ability of the Company or its
subsidiaries to incur additional secured or unsecured debt. However, borrowings
by certain subsidiaries, including MLPF&S, are restricted by net capital
requirements under the Exchange Act and under rules of certain exchanges and
other regulatory bodies. See "Description of the STRYPES--Ranking" in the
ML&Co. Prospectus.
   
PURCHASE AGREEMENT     
   
  Pursuant to the Purchase Agreement described under "Certain Arrangements with
GVI," GVI is obligated to deliver to the ML&Co. Subsidiary immediately prior to
the Maturity Date the Reference Property required by the Company to pay and
discharge all of the STRYPES (including any STRYPES issued pursuant to the
over-allotment option granted by the Company to the Underwriter). In lieu of
delivering the Reference Property immediately prior to the Maturity Date, GVI
has the right to satisfy its obligation under the Purchase Agreement by
delivering at such time cash in an amount equal to the value of such Reference
Property immediately prior to the Maturity Date. Such right, if exercised by
GVI, must be exercised with respect to all of the Reference Property
deliverable pursuant to the Purchase Agreement.     
 
LISTING
   
  The STRYPES have been approved for listing on the NYSE, subject to official
notice of issuance.

                         CERTAIN ARRANGEMENTS WITH GVI
   
  Pursuant to the Purchase Agreement, GVI is obligated to deliver to the ML&Co.
Subsidiary immediately prior to the Maturity Date the Reference Property
required by the Company to pay and discharge all of the STRYPES (including any
STRYPES issued pursuant to the over-allotment option granted by the Company to
the Underwriter). In lieu of delivering the Reference Property immediately
prior to the Maturity Date, GVI has the right to satisfy its obligation under
the Purchase Agreement by delivering at such time cash in an amount equal to
the value of such Reference Property immediately prior to the Maturity Date.
Such right, if exercised by GVI, must be exercised with respect to all of the
Reference Property deliverable pursuant to the Purchase Agreement. Under the
Purchase Agreement, the Company has agreed to pay and discharge the STRYPES by
delivering to the holders thereof on the Maturity Date the form of
consideration that the ML&Co. Subsidiary receives from GVI. The consideration
to be paid by the ML&Co. Subsidiary under the Purchase Agreement is $    in the
aggregate, and is payable to GVI on or about      , 1996. No other
consideration is payable by the ML&Co. Subsidiary to GVI in connection with its
acquisition of the Reference Property pursuant to the Purchase Agreement or the
performance of the Purchase Agreement by GVI. The Company has agreed with GVI
that, without the prior consent of GVI, it will not amend the Indenture in any
respect that would adversely affect any obligation of GVI under the Purchase
Agreement, including, without limitation, increasing the consideration that GVI
is obligated to deliver pursuant to the Purchase Agreement.     
   
  Until such time, if any, as GVI shall have delivered the Reference Property
to the ML&Co. Subsidiary pursuant to the terms of the Purchase Agreement, GVI
will retain all ownership rights with respect to the Reference Property held by
it (including, without limitation, voting rights and rights to receive any
dividends, interest or other distributions in respect thereof).     
   
  GVI has no obligations with respect to the STRYPES or amounts to be paid to
holders thereof, including any obligation to take the needs of the Company or
of holders of the STRYPES into consideration in determining whether to deliver
the Reference Property or cash or for any other reason. The Purchase Agreement
among the Company, the ML&Co. Subsidiary and GVI is a commercial transaction
and does not create any rights in, or for the benefit of, any holder of
STRYPES.     
   
  In the event GVI does not perform under the Purchase Agreement, the Company
will be required to otherwise acquire the Reference Property for delivery to
the holders of the STRYPES on the Maturity Date, unless it elects to exercise
its option to deliver cash with an equal value.     
   
  For more information regarding the relationship between GVI and IMC and the
IMC Common Stock (including the preferred stock purchase rights associated
therewith) that may be delivered to the holders of STRYPES on the Maturity
Date, see the IMC Prospectus which accompanies this Prospectus Supplement and
the ML&Co. Prospectus.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
   
  Set forth in full below is the opinion of Brown & Wood, counsel to the
Company, as to certain United States Federal income tax consequences of the
purchase, ownership and disposition of the STRYPES. Such opinion is based upon
laws, regulations, rulings and decisions now in effect (or, in the case of
certain regulations, in proposed form or in final form but not yet effective),
all of which are subject to change (including retroactive changes in effective
dates) or possible differing interpretations. The discussion below deals only
with STRYPES held as capital assets and does not purport to deal with persons
in special tax situations, such as financial institutions, insurance companies,
regulated investment companies, dealers in securities or currencies, tax-exempt
entities, or persons holding STRYPES as a hedge against currency risks or as a
position in a "straddle" for tax purposes. It also does not deal with holders
of STRYPES other than original purchasers thereof (except where otherwise
specifically noted herein). The following discussion also does not address the
tax consequences of investing in the STRYPES arising under the laws of any
state, local or foreign jurisdiction. Persons considering the purchase of the
STRYPES should consult their own tax advisors concerning the application of the
United States Federal income tax laws to their particular situations as well as
any consequences of the purchase, ownership and disposition of the STRYPES
arising under the laws of any other taxing jurisdiction.     
 
  As used herein, the term "U.S. Holder" means a beneficial owner of a STRYPES
that is for United States Federal income tax purposes (i) a citizen or resident
of the United States, (ii) a corporation, partnership or other entity created
or organized in or under the laws of the United States or of any political
subdivision thereof, (iii) an estate or trust the income of which is subject to
United States Federal income taxation regardless of its source or (iv) any
other person whose income or gain in respect of a STRYPES is effectively
connected with the conduct of a United States trade or business. As used
herein, the term "non-U.S. Holder" means a beneficial owner of a STRYPES that
is not a U.S. Holder.
 
GENERAL
   
  There are no statutory provisions, regulations (except possibly the Treasury
Regulations as described below), published rulings or judicial decisions
addressing or involving the characterization, for United States Federal income
tax purposes, of the STRYPES or securities with terms substantially the same as
the STRYPES. Accordingly, the proper United States Federal income tax
characterization and treatment of the STRYPES is uncertain. Pursuant to the
terms of the Indenture, the Company and any holder of a STRYPES agree to treat
each STRYPES as a unit (a "Unit") consisting of (i) a debt instrument (the
"Debt Instrument") with a fixed principal amount unconditionally payable on the
Maturity Date equal to the issue price of the STRYPES and bearing interest at
the stated interest rate on the STRYPES and (ii) a forward purchase contract
(the "Forward Contract") pursuant to which the holder agrees to use the
principal payment due on the Debt Instrument to purchase on the Maturity Date
the Reference Property which the Company is obligated to deliver at that time
(subject to the Company's right to deliver cash in lieu of the Reference
Property). Therefore, the Company currently intends to treat each STRYPES as a
Unit consisting of the Debt Instrument and the Forward Contract for United
States Federal income tax purposes and, where required, intends to file
information returns with the Internal Revenue Service ("IRS") in accordance
with such treatment, in the absence of any change or clarification in the law,
by regulation or otherwise, requiring a different characterization and
treatment of the STRYPES for United States Federal income tax purposes. In the
opinion of Brown & Wood, counsel to the Company, such characterization and tax
treatment of the STRYPES, although not the only reasonable characterization and
tax treatment, is based on reasonable interpretations of law currently in
effect and, even if successfully challenged by the IRS, will not result in the
imposition of penalties.     
 
  Prospective investors in the STRYPES should be aware, however, that no ruling
is being requested from the IRS with respect to the STRYPES, the IRS is not
bound by the characterization of each STRYPES by the Company and the holders
thereof as a Unit consisting of the Debt Instrument and the Forward Contract,
and the IRS could possibly assert a different position as to the proper United
States Federal income tax characterization and treatment of the STRYPES. For
instance, it is possible that the IRS could assert that
 
                                      S-19
<PAGE>
 
each STRYPES should be treated entirely as a single debt instrument of the
Company for United States Federal income tax purposes. Except where otherwise
specifically provided herein, the following discussion of the principal United
States Federal income tax consequences of the purchase, ownership and
disposition of the STRYPES is based upon the assumption that each STRYPES will
be characterized and treated as a Unit consisting of the Debt Instrument and
the Forward Contract for United States Federal income tax purposes. As
discussed in greater detail herein, if the STRYPES are not in fact ultimately
characterized and treated as a Unit consisting of the Debt Instrument and the
Forward Contract for United States Federal income tax purposes, then the United
States Federal income tax treatment of the purchase, ownership and disposition
of the STRYPES could significantly differ from the treatment discussed
immediately below with the result that the timing and character of income, gain
or loss recognized on a STRYPES could significantly differ from the timing and
character of income, gain or loss recognized on a STRYPES had each STRYPES in
fact been characterized and treated as a Unit consisting of the Debt Instrument
and the Forward Contract for United States Federal income tax purposes.
 
U.S. HOLDERS
   
  As previously discussed, pursuant to the terms of the Indenture, the Company
and any holder of a STRYPES agree to treat each STRYPES as a Unit consisting of
the Debt Instrument and the Forward Contract. Consistent with this treatment of
the STRYPES, pursuant to the terms of the Indenture, a U.S. Holder of a STRYPES
will be required to include currently in income payments denominated as
interest that are made with respect to a STRYPES in accordance with such U.S.
Holder's regular method of tax accounting. Furthermore, pursuant to the
agreement contained in the Indenture to treat each STRYPES as a Unit consisting
of the Debt Instrument and the Forward Contract, any holder of a STRYPES agrees
to allocate the purchase price paid by such holder to acquire the STRYPES
between the two components of the Unit (i.e., the Debt Instrument and the
Forward Contract) based upon their relative fair market values (as determined
on the purchase date). The portion of the total purchase price so allocated by
the holder to each component of the Unit will generally constitute the holder's
initial tax basis for each such component of the Unit. Accordingly, in the
event that the fair market value of the Debt Instrument (as determined on the
purchase date) exceeds the purchase price paid by the holder to acquire the
STRYPES, the holder would be deemed to have acquired the Debt Instrument for an
amount equal to the fair market value of the Debt Instrument (as determined on
the purchase date) and would be deemed to have assumed the Forward Contract
component of the STRYPES in exchange for a payment in an amount equal to the
excess of the fair market value of the Debt Instrument (as determined on the
purchase date) over the purchase price paid by the holder to acquire the
STRYPES. In such event, such deemed payment received by the holder in respect
of the Forward Contract should only be taken into account by the holder as an
additional amount realized with respect to the Forward Contract on the earlier
of the sale or other disposition of the STRYPES by the holder or the Maturity
Date (which would either reduce the holder's tax basis in any Reference
Property received thereby or, if the STRYPES are paid in cash on the Maturity
Date or sold prior to the Maturity Date, increase the amount of gain or
decrease the amount of loss realized with respect to the Forward Contract).
Pursuant to the terms of the Indenture, with respect to acquisitions of STRYPES
in connection with the original issuance thereof, the Company and the holders
agree to allocate $             of the entire initial purchase price of a
STRYPES (i.e., the issue price of a STRYPES) to the Debt Instrument component
and to allocate the remaining $           of the entire initial purchase price
of a STRYPES to the Forward Contract component. Based upon the foregoing,
pursuant to the agreement to treat each STRYPES as a Unit consisting of the
Debt Instrument and the Forward Contract, a holder who acquires a STRYPES in
connection with the original issuance thereof, will have agreed to treat such
acquisition of the STRYPES by the holder as a purchase of the Debt Instrument
by the holder for $           and the making of an initial payment by the
holder with respect to the Forward Contract of $          .     
 
  Under general principles of current United States Federal income tax law,
payments of interest on a debt instrument (e.g., the Debt Instrument) generally
will be taxable to a U.S. Holder as ordinary interest income at the time such
payments are accrued or are received (in accordance with the U.S. Holder's
regular
 
                                      S-20
<PAGE>
 
method of tax accounting). In addition, a debt instrument will be treated as
having been issued with original issue discount for United States Federal
income tax purposes to the extent that the stated redemption price at maturity
of the debt instrument (generally the debt instrument's stated principal
amount) exceeds the debt instrument's issue price, if such excess equals or
exceeds a de minimis amount (generally 1/4 of 1% of the debt instrument's
stated redemption price at maturity multiplied by the number of complete years
to maturity from its issue date). Pursuant to the agreement to treat each
STRYPES as a Unit consisting of the Debt Instrument and the Forward Contract,
each such Debt Instrument component will be treated, for these purposes as
having an issue price equal to $          . Since the stated redemption price
at maturity of each such Debt Instrument component (i.e., $          ) does not
exceed its issue price (i.e., $          ) by an amount that is equal to or
greater than $           (i.e., the applicable de minimis amount), the Debt
Instrument component of each Unit will not be treated as having been issued
with any original issue discount.
   
  Under the foregoing principles and in accordance with the agreement to treat
each STRYPES as a Unit consisting of the Debt Instrument and the Forward
Contract, the quarterly interest payments payable with respect to the STRYPES
at the stated interest rate of    % of the issue price of the STRYPES per annum
(the "Interest Payments") generally will be taxable to a U.S. Holder as
ordinary interest income on the respective dates that such Interest Payments
are accrued or are received (in accordance with the U.S. Holder's regular
method of tax accounting). On the Maturity Date, pursuant to the agreement to
treat each STRYPES as a Unit consisting of the Debt Instrument and the Forward
Contract, a U.S. Holder will recognize capital gain or loss with respect to the
Debt Instrument in an amount equal to the difference, if any, between the
principal amount of the Debt Instrument (i.e., the issue price of the STRYPES)
and such U.S. Holder's adjusted tax basis in the Debt Instrument. Such capital
gain or loss will generally be long-term capital gain or loss if the STRYPES
has been held by the U.S. Holder for more than one year as of the Maturity
Date. In addition, pursuant to the agreement to treat each STRYPES as a Unit
consisting of the Debt Instrument and the Forward Contract, on the Maturity
Date, if the Company delivers Reference Property upon payment of the STRYPES, a
U.S. Holder will generally not realize any taxable gain or loss on the
exchange, pursuant to the Forward Contract, of the principal amount of the Debt
Instrument for the Reference Property. However, a U.S. Holder will generally be
required to recognize taxable gain or loss with respect to any cash received in
lieu of fractional interests and any Reference Property consisting of cash. The
amount of such gain or loss recognized by a U.S. Holder will be equal to the
difference, if any, between the amount of cash received by the U.S. Holder and
the portion of the sum of the principal amount of the Debt Instrument and the
U.S. Holder's tax basis in the Forward Contract that is allocable to the
fractional interests and any Reference Property consisting of cash. Any such
taxable gain or loss attributable to cash received in lieu of fractional
interests will be treated as short-term capital gain or loss, and, because the
matter is uncertain, any such taxable gain or loss attributable to any
Reference Property consisting of cash could be treated as short-term capital
gain or loss, as long-term or short-term capital gain or loss (depending upon
the U.S. Holder's holding period for the STRYPES), or as ordinary income or
loss. A U.S. Holder will have an initial tax basis (as allocated among the
Reference Property in accordance with the relative fair market values thereof,
as determined on the Maturity Date) in any Reference Property (other than any
cash received in lieu of fractional interests and any Reference Property
consisting of cash) received on the Maturity Date in an amount equal to the sum
of the principal amount of the Debt Instrument and the U.S. Holder's tax basis
in the Forward Contract less the portion of such sum that is allocable to any
fractional interests and any Reference Property consisting of cash (as
described above) and will realize taxable gain or loss with respect to such
Reference Property received on the Maturity Date only upon the subsequent sale
or disposition by the U.S. Holder of such Reference Property. In addition, a
U.S. Holder's holding period for any Reference Property received by such U.S.
Holder on the Maturity Date will begin on the day immediately following the
Maturity Date and will not include the period during which the U.S. Holder held
such STRYPES.     
 
  Alternatively, pursuant to the agreement to treat the STRYPES as a Unit
consisting of the Debt Instrument and the Forward Contract, if the Company pays
the STRYPES in cash on the Maturity Date, a U.S. Holder will recognize taxable
gain or loss on the Maturity Date with respect to the Forward Contract (in
addition to any gain or loss recognized with respect to the Debt Instrument as
described above) in an
 
                                      S-21
<PAGE>
 
   
amount equal to the difference, if any, between the total amount of cash
received by such U.S. Holder on the Maturity Date and an amount equal to the
sum of the principal amount of the Debt Instrument and the U.S. Holder's tax
basis in the Forward Contract. It is uncertain whether such gain or loss would
be treated as capital or ordinary gain or loss. If such gain or loss is
properly treated as capital gain or loss, then such gain or loss generally will
be treated as long-term capital gain or loss if the STRYPES has been held by
the U.S. Holder for more than one year as of the Maturity Date. If such gain or
loss is properly treated as ordinary gain or loss, it is possible that the
deductibility of any loss recognized on the Maturity Date with respect to the
Forward Contract by a U.S. Holder who is an individual could be subject to the
limitations applicable to miscellaneous itemized deductions provided for under
Section 67(a) of the Internal Revenue Code of 1986, as amended (the "Code"). In
general, Section 67(a) of the Code provides that an individual may only deduct
miscellaneous itemized deductions for a particular taxable year to the extent
that the aggregate amount of the individual's miscellaneous itemized deductions
for such taxable year exceed two percent of the individual's adjusted gross
income for such taxable year (although, the miscellaneous itemized deductions
allowable to high-income individuals are generally subject to further
limitations). Prospective investors in the STRYPES are urged to consult their
own tax advisors concerning the character of any gain or loss realized on the
Maturity Date with respect to the Forward Contract in the event that either (i)
the Reference Property consists of cash, securities (other than IMC Common
Stock) or other property or (ii) the Company elects to pay the STRYPES in cash
on the Maturity Date as well as the deductibility of any such loss.     
   
  Pursuant to the agreement to treat each STRYPES as a Unit consisting of the
Debt Instrument and the Forward Contract, upon the sale or other disposition of
a STRYPES prior to the Maturity Date, a U.S. Holder generally will be required
to allocate the total amount realized by such U.S. Holder upon such sale or
other disposition (other than amounts representing accrued and unpaid Interest
Payments) between the two components of the Unit (i.e., the Debt Instrument and
the Forward Contract) based upon their relative fair market values (as
determined on the date of disposition). Accordingly, in the event that the fair
market value of the Debt Instrument (as determined on the date of disposition)
exceeds the actual amount realized by the U.S. Holder upon the sale or other
disposition of a STRYPES prior to the Maturity Date, the U.S. Holder would be
deemed to have sold the Debt Instrument for an amount equal to the fair market
value of the Debt Instrument (as determined on the date of disposition) and
would be deemed to have made a payment to the purchaser of the STRYPES in
exchange for such purchaser's assumption of the Forward Contract in an amount
equal to the excess of the fair market value of the Debt Instrument (as
determined on the date of disposition) over the actual amount realized by the
U.S. Holder upon such sale or disposition of the STRYPES. A U.S. Holder will
generally be required to recognize taxable gain or loss with respect to each
such component in an amount equal to the difference, if any, between (or, in
some cases, the sum of) the amount realized (or paid) with respect to each such
component upon the sale or disposition of the STRYPES (as determined in the
manner described above) and the U.S. Holder's adjusted tax basis in each such
component (or, the amount deemed to have been realized by the U.S. Holder in
respect of the Forward Contract). Any such gain or loss will generally be
treated as long-term capital gain or loss if the U.S. Holder has held the
STRYPES for more than one year at the time of disposition.     
 
  As previously discussed, prospective investors in the STRYPES should be aware
that the IRS is not bound by the characterization of the STRYPES by the Company
and the holders thereof as a Unit consisting of the Debt Instrument and the
Forward Contract, and the IRS could possibly assert a different position as to
the proper United States Federal income tax characterization and treatment of
the STRYPES. For instance, it is possible that the IRS could assert that each
STRYPES should be treated entirely as a single debt instrument of the Company
for United States Federal income tax purposes.
 
  If the STRYPES were ultimately characterized and treated entirely as debt
instruments of the Company for United States Federal income tax purposes, then
the timing and character of income, gain or loss recognized on a STRYPES would
differ from the timing and character of income, gain or loss recognized on a
STRYPES had each STRYPES in fact been characterized and treated for United
States Federal income tax purposes as a Unit consisting of the Debt Instrument
and the Forward Contract. If the STRYPES were
 
                                      S-22
<PAGE>
 
   
ultimately characterized and treated entirely as indebtedness of the Company
for United States Federal income tax purposes, under general principles of
current United States Federal income tax law, the Interest Payments generally
would be taxable to a U.S. Holder as ordinary interest income on the respective
dates that such Interest Payments are accrued or are received (in accordance
with the U.S. Holder's regular method of tax accounting). Under this same
analysis and treatment of each STRYPES as a single debt instrument of the
Company for United States Federal income tax purposes, under general principles
of current United States Federal income tax law, if the fair market value (as
determined on the Maturity Date) of the amount of Reference Property or cash in
lieu thereof payable on the Maturity Date with respect to a STRYPES exceeds the
issue price thereof, such excess could be treated as contingent interest and,
if so treated, generally would be includible in income by a U.S. Holder as
ordinary interest on the Maturity Date (regardless of the U.S. Holder's regular
method of tax accounting). In addition, if the fair market value (as determined
on the Maturity Date) of the Reference Property or cash in lieu thereof payable
on the Maturity Date with respect to a STRYPES exceeds the issue price thereof,
then such STRYPES would be treated as having been retired on the Maturity Date
in exchange for an amount equal to the issue price thereof. If, however, the
fair market value (as determined on the Maturity Date) of the Reference
Property or cash in lieu thereof payable on the Maturity Date with respect to a
STRYPES is equal to or less than the issue price thereof, then such STRYPES
would be treated as having been retired on the Maturity Date in exchange for an
amount equal to the fair market value (as determined on the Maturity Date) of
the entire amount payable on the Maturity Date with respect to such STRYPES and
no portion of the amount payable on the Maturity Date with respect to such
STRYPES would be treated as contingent interest. A U.S. Holder's initial tax
basis in any Reference Property received by such U.S. Holder on the Maturity
Date of a STRYPES would equal the fair market value (as determined on the
Maturity Date) of the Reference Property received by such U.S. Holder.
Furthermore, a U.S. Holder's holding period for any Reference Property received
by such U.S. Holder on the Maturity Date of a STRYPES would begin on the day
immediately following the Maturity Date and would not include the period during
which the U.S. Holder held such STRYPES.     
 
  Moreover, under this analysis and treatment of each STRYPES as a single debt
instrument of the Company for United States Federal income tax purposes, upon
the sale, exchange or retirement of a STRYPES, a U.S. Holder generally would
recognize taxable gain or loss in an amount equal to the difference, if any,
between the amount realized on the sale, exchange or retirement (other than
amounts representing accrued and unpaid Interest Payments) and such U.S.
Holder's adjusted tax basis in the STRYPES. A U.S. Holder's adjusted tax basis
in a STRYPES generally would equal such U.S. Holder's initial investment in the
STRYPES (as adjusted pursuant to the market discount and bond premium rules
described below). Such gain or loss generally would be long-term capital gain
or loss if the STRYPES were held by the U.S. Holder for more than one year
(subject to the market discount rules, as discussed below). It is possible,
however, that under this analysis and treatment of the STRYPES the IRS could
assert that any amounts realized upon the sale or exchange of a STRYPES prior
to the Maturity Date in excess of the STRYPES issue price constitutes ordinary
interest income (subject to the bond premium rules, as discussed below).
Nonetheless, if the STRYPES were ultimately characterized and treated entirely
as indebtedness of the Company for United States Federal income tax purposes,
although the matter is not free from doubt, in the opinion of Brown & Wood,
counsel to the Company, under current law, any gain realized upon the sale or
exchange of a STRYPES prior to the Maturity Date should be treated entirely as
capital gain (subject to the market discount rules, as discussed below).
   
  Prospective investors in the STRYPES should also be aware that on June 11,
1996, the Treasury Department issued final regulations (the "Treasury
Regulations") concerning the proper United States Federal income tax treatment
of contingent payment debt instruments. In the event that the STRYPES were
characterized and treated entirely as debt instruments of the Company for
United States Federal income tax purposes, the STRYPES would be treated as
contingent payment debt instruments. The Treasury Regulations, however, only
apply to debt instruments issued on or after August 13, 1996. Accordingly, due
to the effective date of the Treasury Regulations, the Treasury Regulations
will not apply to the STRYPES even if the STRYPES were characterized and
treated entirely as debt instruments of the Company for United     
 
                                      S-23
<PAGE>
 
   
States Federal income tax purposes. In general, the Treasury Regulations would
cause the timing and character of income, gain or loss reported on a contingent
payment debt instrument to substantially differ from the timing and character
of income, gain or loss reported on a contingent payment debt instrument under
general principles of current United States Federal income tax law (as
described immediately above). The Treasury Regulations provide no definitive
guidance as to whether or not an instrument is properly characterized as a
single debt instrument for United States Federal income tax purposes.
Prospective investors in the STRYPES are urged to consult their own tax
advisors concerning the effect, if any, of the Treasury Regulations on their
investment in the STRYPES.     
 
  Prospective investors in the STRYPES should also be aware that it is possible
that the ultimate characterization and treatment of the STRYPES for United
States Federal income tax purposes could differ from the possible
characterizations and treatments described herein with the result that the
ultimate United States Federal income tax treatment of the purchase, ownership
and disposition of the STRYPES could significantly differ from any of the
treatments described herein.
 
  Despite the foregoing, as previously discussed, pursuant to the agreement
contained in the Indenture to treat each STRYPES as a Unit consisting of the
Debt Instrument and the Forward Contract, the Company, where required,
currently intends to file information returns with the IRS treating each
STRYPES as a Unit consisting of the Debt Instrument and the Forward Contract
for United States Federal income tax purposes (as described above), in the
absence of any change or clarification in the law, by regulation or otherwise,
requiring another characterization and treatment of the STRYPES for United
States Federal income tax purposes.
 
MARKET DISCOUNT AND PREMIUM
 
  In general, if a U.S. Holder purchases a debt instrument (e.g., the Debt
Instrument component of a Unit) for an amount that is less than the principal
amount thereof, the amount of the difference will be treated as "market
discount," unless such difference is less than a specified de minimis amount
(generally 1/4 of 1% of the debt instrument's stated principal amount
multiplied by the number of complete years to maturity from the date the U.S.
Holder purchased such debt instrument).
 
  Under the market discount rules, a U.S. Holder will be required to treat any
gain realized on the sale, exchange, retirement or other disposition of a debt
instrument as ordinary income to the extent of the lesser of (i) the amount of
such realized gain or (ii) the market discount which has not previously been
included in income and is treated as having accrued on such debt instrument at
the time of such payment or disposition. Market discount will be considered to
accrue ratably during the period from the date of acquisition to the maturity
of the debt instrument, unless the U.S. Holder elects to accrue market discount
on the basis of semiannual compounding.
 
  A U.S. Holder may be required to defer the deduction of all or a portion of
the interest paid or accrued on any indebtedness incurred or maintained to
purchase or carry a debt instrument with market discount until the maturity of
the debt instrument or its earlier disposition in a taxable transaction and
certain nontaxable transactions, because a current deduction is only allowed to
the extent that the interest expense exceeds an allocable portion of the market
discount. A U.S. Holder may elect to include market discount in income
currently as it accrues (on either a ratable or semiannual compounding basis),
in which case the rules described above regarding the deferral of interest
deductions will not apply. Generally, such currently included market discount
is treated as ordinary interest income for United States Federal income tax
purposes and a U.S. Holder would increase its tax basis in a debt instrument by
the amount of any such currently included market discount. Such an election
will apply to all debt instruments acquired by the U.S. Holder on or after the
first day of the first taxable year to which such election applies and may be
revoked only with the consent of the IRS.
 
  In general, if a U.S. Holder purchases a debt instrument for an amount that
is greater than the principal amount thereof, such U.S. Holder will be
considered to have purchased the debt instrument with
 
                                      S-24
<PAGE>
 
"amortizable bond premium" equal in amount to such excess. A U.S. Holder may
elect to amortize such premium using a constant yield method over the remaining
term of the debt instrument and may offset ordinary interest otherwise required
to be included in respect of the debt instrument during any taxable year by the
amortized amount of such premium for such year (or, prior years, if such
amortized premium for prior years has not yet offset interest) and would reduce
its tax basis in the debt instrument by the amount of any such interest offset
taken. Such election, if made, would apply to all debt instruments held by the
U.S. Holder at the beginning of the taxable year to which such election applies
and to all debt instruments acquired by the U.S. Holder thereafter. Such
election would also be irrevocable once made, unless the U.S. Holder making
such an election obtains the express written consent of the IRS to revoke such
election.
 
MISCELLANEOUS TAX MATTERS
 
  Special tax rules may apply to persons holding a STRYPES as part of a
"synthetic security" or other integrated investment, or as part of a straddle,
hedging transaction or other combination of offsetting positions. For instance,
Section 1258 of the Code may possibly require certain U.S. Holders of the
STRYPES who enter into hedging transactions or offsetting positions with
respect to the STRYPES to treat all or a portion of any gain realized on the
STRYPES as ordinary income in instances where such gain may have otherwise been
treated as capital gain. U.S. Holders hedging their positions with respect to
the STRYPES or otherwise holding their STRYPES in a manner described above
should consult their own tax advisors regarding the applicability of Section
1258 of the Code, or any other provision of the Code, to their investment in
the STRYPES.
 
NON-U.S. HOLDERS
 
  Based on the treatment of each STRYPES as a Unit consisting of the Debt
Instrument and the Forward Contract, in the case of a non-U.S. Holder, payments
made with respect to the STRYPES should not be subject to United States
withholding tax, provided that such non-U.S. Holder complies with applicable
certification requirements. Any capital gain realized upon the sale or other
disposition of a STRYPES by a non-U.S. Holder will generally not be subject to
United States Federal income tax if (i) such gain is not effectively connected
with a United States trade or business of such non-U.S. Holder and (ii) in the
case of an individual non-U.S. Holder, such individual is not present in the
United States for 183 days or more in the taxable year of the sale or other
disposition, or the gain is not attributable to a fixed place of business
maintained by such individual in the United States and such individual does not
have a "tax home" (as defined for United States Federal income tax purposes) in
the United States.
 
  As discussed above, alternative characterizations of the STRYPES for United
States Federal income tax purposes are possible. Should an alternative
characterization of the STRYPES, by reason of a change or clarification of the
law, by regulation or otherwise, cause payments with respect to the STRYPES to
become subject to withholding tax, the Company will withhold tax at the
statutory rate. Prospective non-U.S. Holders of the STRYPES should consult
their own tax advisors in this regard.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
  A beneficial owner of a STRYPES may be subject to information reporting and
to backup withholding at a rate of 31 percent of certain amounts paid to the
beneficial owner unless such beneficial owner provides proof of an applicable
exemption or a correct taxpayer identification number, and otherwise complies
with applicable requirements of the backup withholding rules.
 
  Any amounts withheld under the backup withholding rules from a payment to a
beneficial owner would be allowed as a refund or a credit against such
beneficial owner's United States Federal income tax provided the required
information is furnished to the IRS.

                                  -----------
 
  Merrill Lynch & Co., Inc. (the "Company") intends to sell from time to time
its Structured Yield Product Exchangeable for Stock SM, STRYPES SM. The STRYPES
will be offered to the public in series and on terms determined by market
conditions at the time of sale and set forth in the accompanying prospectus
supplement (the "Prospectus Supplement"). The STRYPES will be unsecured
obligations of the Company ranking pari passu with all of its other unsecured
and unsubordinated indebtedness. See "Description of the STRYPES--Ranking."
 
  On the maturity date of each series of STRYPES (the "Maturity Date"), the
Company will pay and discharge such STRYPES by delivering to the holder thereof
a number of shares of common stock or other securities (the "Underlying
Securities") of the unaffiliated corporation identified in the Prospectus
Supplement (the "Underlying Issuer") determined in accordance with a payment
rate formula specified in the Prospectus Supplement (subject to the Company's
right to deliver, with respect to all, but not less than all, STRYPES of such
series, cash with an equal value). THERE CAN BE NO ASSURANCE THAT THE VALUE OF
THE UNDERLYING SECURITIES (OR CASH) PAYABLE TO HOLDERS OF A SERIES OF STRYPES
ON THE MATURITY DATE WILL BE EQUAL TO OR GREATER THAN THE ISSUE PRICE OF SUCH
STRYPES. IF THE VALUE OF THE UNDERLYING SECURITIES (OR CASH) RECEIVED ON THE
MATURITY DATE OF A SERIES OF STRYPES IS LESS THAN THE ISSUE PRICE PAID FOR SUCH
STRYPES, AN INVESTMENT IN STRYPES WILL RESULT IN A LOSS. SEE "DESCRIPTION OF
THE STRYPES."
 
  Each series of STRYPES may vary, where applicable, as to aggregate issue
price, Maturity Date, Underlying Issuer, Underlying Securities deliverable upon
maturity, formula or other method by which the amount of such Underlying
Securities will be determined, public offering or purchase price, interest rate
or rates, if any, and timing of payments thereof, provision for redemption,
currencies of denomination or currencies otherwise applicable thereto and any
other variable terms and method of distribution. The accompanying Prospectus
Supplement sets forth the specific terms with regard to the series of STRYPES
in respect of which this Prospectus is being delivered.
 
  Reference is made to any accompanying prospectus of the Underlying Issuer
covering the Underlying Securities which may be received by holders of a series
of STRYPES on the Maturity Date.

                           MERRILL LYNCH & CO., INC.
 
  Merrill Lynch & Co., Inc. is a holding company that, through its subsidiaries
and affiliates, provides investment, financing, insurance, and related services
on a global basis. Its principal subsidiary, MLPF&S, one of the largest
securities firms in the world, is a leading broker in securities, options
contracts, and commodity and financial futures contracts; a leading dealer in
options and in corporate and municipal securities; a leading investment banking
firm that provides advice to, and raises capital for, its clients; and an
underwriter of selected insurance products. Other subsidiaries provide
financial services on a global basis similar to those of MLPF&S and are engaged
in such other activities as international banking, lending, and providing other
investment and financing services. Merrill Lynch International Incorporated,
through subsidiaries and affiliates, provides investment, financing, and
related services outside the United States and Canada. Merrill Lynch Asset
Management, LP and Fund Asset Management, LP together constitute one of the
largest mutual fund managers in the world and provide investment advisory
services. Merrill Lynch Government Securities Inc. is a primary dealer in
obligations issued or guaranteed by the U.S. Government and its agencies.
Merrill Lynch Capital Services, Inc., Merrill Lynch Derivative Products, Inc.,
and Merrill Lynch Capital Markets PLC are the Company's primary derivative
product dealers and enter into interest rate and currency swaps and other
derivative transactions as intermediaries and as principals. The Company's
insurance underwriting operations consist of the underwriting of life insurance
and annuity products. Banking, trust, and mortgage lending operations conducted
through subsidiaries of the Company include issuing certificates of deposit,
offering money market deposit accounts, making secured loans, and providing
foreign exchange trading facilities and other related services.
 
  The principal executive office of the Company is located at World Financial
Center, North Tower, 250 Vesey Street, New York, New York 10281; its telephone
number is (212) 449-1000.
 
                                USE OF PROCEEDS
 
  The Company intends to use the net proceeds from the sale of the STRYPES for
general corporate purposes. Such uses may include the funding of investments
in, or extensions of credit to, its subsidiaries, the funding of assets held by
the Company or its subsidiaries, including securities inventories, customer
receivables and loans (including business loans, home equity loans, and loans
in connection with investment banking-related merger and acquisition
activities), and the refunding of maturing indebtedness. The precise amount and
timing of investments in, and extensions of credit to, its subsidiaries will
depend upon their funding requirements and the availability of other funds to
the Company and its subsidiaries. Pending such applications, the net proceeds
will be temporarily invested or applied to the reduction of short-term
indebtedness. Management of the Company expects that it will, on a recurrent
basis, engage in additional financings as the need arises to finance the growth
of the Company or to lengthen the average maturity of its borrowings. To the
extent that STRYPES being purchased for resale by MLPF&S are not resold, the
aggregate proceeds to the Company and its subsidiaries would be reduced.

                         SUMMARY FINANCIAL INFORMATION
 
  The following summary of consolidated financial information was derived from,
and is qualified in its entirety by reference to, the financial statements and
other information and data contained in the Company's Annual Report on Form 10-
K for the year ended December 29, 1995 and Quarterly Report on Form 10-Q for
the period ended March 29, 1996 (the "Quarterly Report"). See "Incorporation of
Certain Documents by Reference." The condensed consolidated financial
statements contained in the Quarterly Report are unaudited; however, in the
opinion of management of the Company, all adjustments, consisting only of
normal recurring accruals, necessary for a fair statement of the results of
operations have been included. The year-end results include 52 weeks for 1991,
1992, 1994, and 1995 and 53 weeks for 1993.
 
  The Company conducts its business in highly volatile markets. Consequently,
the Company's results can be affected by many factors, including general market
conditions, the liquidity of secondary markets, the level and volatility of
interest rates and currency values, the valuation of securities positions,
competitive conditions, and the size, number, and timing of transactions. In
periods of unfavorable market activity, profitability can be adversely affected
because certain expenses remain relatively fixed. As a result, net earnings and
revenues can vary significantly from period to period.

(1) Net earnings for 1992 have been reduced by $58 million to reflect the
  adoption of Statement of Financial Accounting Standards ("SFAS") No. 106,
  Employers' Accounting for Postretirement Benefits Other than Pensions, and
  SFAS No. 109, Accounting for Income Taxes. Net earnings for 1993 were reduced
  by $35 million to reflect the adoption of SFAS No. 112, Employers' Accounting
  for Postemployment Benefits.
(2) For the purpose of calculating the ratio of earnings to fixed charges,
  "earnings" consists of earnings from continuing operations before income
  taxes and fixed charges. "Fixed charges" consists of interest costs,
  amortization of debt expense, preferred stock dividend requirements of
  majority-owned subsidiaries, and that portion of rentals estimated to be
  representative of the interest factor.
(3) In 1994, the Company adopted Financial Accounting Standards Board ("FASB")
  Interpretation No. 39, Offsetting of Amounts Related to Certain Contracts,
  and FASB Interpretation No. 41, Offsetting of Amounts Related to Certain
  Repurchase and Reverse Repurchase Agreements, which increased assets and
  liabilities at December 30, 1994 by approximately $8,500 million.
   
(4) To finance its diverse activities, the Company and certain of its
  subsidiaries borrow substantial amounts of short-term funds on a regular
  basis. Although the amount of short-term borrowings varies significantly with
  the level of general business activity, on March 29, 1996, $526 million of
  bank loans and $17,222 million of commercial paper were outstanding. In
  addition, certain of the Company's subsidiaries lend securities and enter
  into repurchase agreements to obtain financing. At March 29, 1996, cash
  deposits for securities loaned and securities sold under agreements to
  repurchase amounted to $3,768 million and $61,657 million, respectively. From
  March 30, 1996 to June 14, 1996, long-term borrowings, net of repayments and
  repurchases, increased by approximately $1,683 million.

FISCAL YEAR 1995
 
  Global financial markets, which steadily weakened during most of 1994,
generally improved during 1995, led by a more stable U.S. economy, declining
interest rates, and heightened investor activity. Inflationary fears eased
throughout 1995 as key U.S. economic statistics indicated slow to moderate
growth. The Federal Reserve decreased short-term interest rates in July and
December 1995 following seven rate increases between February 1994 and February
1995. Investors reacted favorably to these events and were more active in stock
and bond markets during 1995. Net earnings for the 1995 fourth quarter were
$303 million, up 1% from the 1995 third quarter and up 88% from the 1994 fourth
quarter.
 
  Net earnings for 1995 were $1,114 million, up 10% from 1994 net earnings of
$1,017 million. Earnings per common share were $5.44 primary and $5.42 fully
diluted in 1995, compared with $4.75 primary and $4.74 fully diluted in 1994.
 
  Total revenues were a record $21,513 million, up 18% from 1994. Net revenues
(revenues after interest expense) totaled $10,265 million in 1995, up 7% from
1994.
 
  Commission revenues increased 9% to a record $3,126 million from $2,871
million in 1994, due primarily to higher levels of listed and over-the-counter
securities transactions and mutual fund commissions, partially offset by lower
revenues from commodities. Commissions from listed and over-the-counter
securities increased due primarily to higher trading volumes on most major U.S.
and international exchanges. Mutual fund commissions increased due primarily to
higher distribution and redemption fees. Distribution fees from deferred-charge
funds increased due to strong fund sales in prior periods and higher asset
levels. Redemption fees increased as clients repositioned invested assets.
 
  Interest and dividend revenues increased 28% to $12,221 million from $9,578
million in 1994. Interest expense, which includes dividend expense, increased
31% from 1994 to $11,248 million. Net interest and dividend profit was $973
million, virtually unchanged from $969 million in 1994, with increases in net
interest-earning assets offset by declining interest spreads due to the
flattening of the U.S. Treasury yield curve. The change in the yield curve
resulted from long-term interest rates falling more than short-term rates
during 1995.
 
  Principal transactions revenues increased 8% from 1994 to $2,519 million in
1995. Increases in equities and equity derivatives and taxable fixed-income
trading revenues were partially offset by decreases in trading revenues from
municipal securities, foreign exchange and commodities, and interest rate and
currency swaps. Equities and equity derivatives trading revenues, in the
aggregate, increased 46% to $912 million, due primarily to improved volumes in
the convertible, over-the-counter, and international equities markets,
partially offset by lower equity derivatives trading revenues. Taxable fixed-
income trading revenues increased 10% to $516 million due, in part, to higher
revenues from corporate bonds and preferred stock, high-yield bonds, and non-
U.S. governments and agencies securities. Trading revenues from mortgage-backed
products were negatively affected by reduced market liquidity, leading to a
loss. Nevertheless, trading results from mortgage-backed products, which
include related net interest revenues, were positive. U.S. Government and
agencies securities trading revenues were down from 1994 due to tighter spreads
between U.S. Treasury securities and related futures hedges, as well as reduced
retail investor demand attributable to lower interest rates. Municipal
securities revenues decreased 28% to $273 million as a result of decreased
investor demand for tax-exempt investments as investors remained wary of
potential tax law changes and sought higher returns in equity and taxable
fixed-income securities. Foreign exchange and commodities revenues, in the
aggregate, declined 22% to $86 million. Commodities trading revenues decreased
due to lower volumes. Increases in foreign exchange trading revenues resulted
from higher customer volume caused by the strengthening of the U.S. dollar
versus other major currencies during 1995. Interest rate and currency swaps
revenues declined 2% to $732 million. Decreases in U.S. dollar-denominated
transactions were substantially offset by increased revenues in non-dollar-
denominated transactions, particularly in Japanese and European markets.

  Investment banking revenues were $1,308 million, up 5% from $1,240 million in
1994. Strategic services revenues, which include fees for merger and
acquisition activity, debt restructuring, and other advisory services,
increased, as companies worldwide sought strategic partners to promote growth
while cutting costs and increasing efficiencies. Underwriting revenues were
down, as lower revenues from equities, private placements, high-yield debt, and
mortgage-backed securities underwriting were partially offset by increased
underwriting revenues from corporate bonds and preferred stock and defined
asset funds.
 
  Asset management and portfolio service fees rose 9% in 1995 to a record
$1,890 million from $1,739 million in 1994, as a result of higher fees earned
from asset management and other fee-based services. Other revenues decreased 5%
from 1994 to $449 million, due to lower net realized investment gains in 1995
compared with 1994.
 
  Non-interest expenses were $8,454 million, up 7% from $7,895 million in the
year-ago period. Compensation and benefits expense, which represented
approximately 62% of non-interest expenses, increased 6% due primarily to
increased production-related and incentive compensation and the addition of
Smith New Court PLC ("Smith New Court") employees. Compensation and benefits
expense as a percentage of net revenues was 51.3% in 1995, compared with 51.5%
in 1994.
 
  Occupancy costs increased 3% from 1994 primarily due to international growth.
Other facilities-related costs, which include communications and equipment
rental expense and depreciation and amortization expenses, rose 13% primarily
due to expanded use of market data services, as well as higher depreciation
expense from the purchase of technology-related assets over the past year.
 
  Professional fees increased 16% from the year-ago period, due to higher legal
fees and systems development costs related to upgrading technology and
processing capabilities in customer, trading, and transaction processing
systems. Advertising and market development expenses increased 6% from 1994 as
a result of increased advertising, international travel, and sales promotion
primarily related to international growth. Brokerage, clearing, and exchange
fees increased 7% as a result of higher securities volume, particularly in
international markets. Other expenses increased 4% from 1994, due primarily to
a $26 million first quarter charge for the write-off of assets related to a
technology contract and $14 million of goodwill amortization related to Smith
New Court.
 
  Income tax expense totaled $697 million in 1995. The effective tax rate in
1995 was 38.5%, compared with 41.2% in 1994. The decrease in the effective tax
rate was attributable to lower state income taxes, expanded international
business activities in jurisdictions with lower tax rates, and increases in
deductions for dividends received.
 
  In 1995 the Company acquired Smith New Court, a U.K.-based global securities
firm, for approximately $800 million. The Company recorded approximately $530
million of goodwill related to the acquisition, which is being amortized on a
straight-line basis over 15 years. The Company's 1995 results include those of
Smith New Court since mid-August 1995.
 
CERTAIN BALANCE SHEET INFORMATION AS OF DECEMBER 29, 1995
 
  The Company believes that its equity base is adequate relative to the level
and composition of its assets and the mix of its business.
 
  In the normal course of business, the Company underwrites, trades, and holds
non-investment grade securities in connection with its investment banking,
market-making, and derivative structuring activities. These activities are
subject to risks related to the creditworthiness of the issuers of, and the
liquidity of the market for, such securities, in addition to the usual risks
associated with investing in, financing, underwriting, and trading in
investment grade instruments.

  At December 29, 1995, the fair value of long and short non-investment grade
trading inventories amounted to $5,489 million and $353 million, respectively,
and in the aggregate (i.e. the sum of long and short trading inventories)
represented 6.3% of aggregate consolidated trading inventories.
 
  At December 29, 1995, the carrying value of extensions of credit provided to
corporations entering into leveraged transactions aggregated $489 million
(excluding unutilized revolving lines of credit and other lending commitments
of $127 million), consisting primarily of senior term and subordinated
financings to 30 medium-sized corporations. At December 29, 1995, the Company
had no bridge loans outstanding. Loans to highly leveraged corporations are
carried at unpaid principal balances less a reserve for estimated losses. The
allowance for loan losses is estimated based on a review of each loan, and
consideration of economic, market, and credit conditions. Direct equity
investments made in conjunction with the Company's investment and merchant
banking activities aggregated $211 million at December 29, 1995, representing
investments in 62 enterprises. Equity investments in privately-held companies
for which sale is restricted by government or contractual requirements are
carried at the lower of cost or estimated net realizable value. At December 29,
1995, the Company held interests in partnerships, totaling $91 million
(recorded on the cost basis), that invest in highly leveraged transactions and
non-investment grade securities. At December 29, 1995, the Company also
committed to invest an additional $79 million in partnerships that invest in
leveraged transactions.
 
  The Company's insurance subsidiaries hold non-investment grade securities.
Non-investment grade securities were 4.2% of total insurance investments at
December 29, 1995. Non-investment grade securities of insurance subsidiaries
are classified as available-for-sale and are carried at fair value.
 
  At December 29, 1995, the largest non-investment grade concentration
consisted of various issues of a South American sovereign totaling $674
million, of which $672 million represented on-balance-sheet hedges for off-
balance-sheet financial instruments. No one industry sector accounted for more
than 35% of total non-investment grade positions. At December 29, 1995, the
Company held an aggregate carrying value of $164 million in debt and equity
securities of issuers in various stages of bankruptcy proceedings or in
default, of which 75% resulted from the Company's market-making activities in
such securities.
 
FIRST QUARTER 1996
 
  Global financial markets were generally strong during 1995, led by a stable
U.S. economy, declining interest rates, and heightened investor activity.
Market expectations for additional declines in interest rates continued through
February 1996, fueling further market advances, strong investor and issuer
activity, higher fee-based revenues, and improved trading profits industrywide.
In March 1996, inflationary fears were stirred by the release of U.S. economic
statistics indicating stronger than anticipated growth and the Federal
Reserve's decision to hold short-term interest rates at current levels. This
led to increases in long-term interest rates and greater market volatility,
although interest rates remained low relative to the year-ago period.
 
  Net earnings for the 1996 first quarter were a record $409 million, up 80%
from 1995 first quarter net earnings of $228 million. Earnings per common share
were $2.03 primary and fully diluted in the 1996 first quarter, compared with
$1.08 primary and fully diluted in the 1995 first quarter. Total revenues were
a record $6,019 million in the first quarter of 1996, up 16% from the 1995
first quarter. Net revenues (revenues after interest expense) totaled $3,261
million in the first quarter of 1996, up 35% from the 1995 first quarter.
 
  Commissions revenues rose 44% to a record $989 million from $685 million in
the 1995 first quarter. Commissions revenues from listed and over-the-counter
securities increased to record levels due to higher trading volumes on most
major U.S. and international exchanges. Mutual fund commissions advanced to
record levels due to strong sales of both domestic and offshore funds.
 
  Interest and dividend revenues decreased to $3,010 million from $3,030
million in the 1995 first quarter. Interest expense, which includes dividend
expense, decreased to $2,758 million from $2,783 million in the year-ago
quarter. Net interest and dividend profit was $252 million, up slightly from
$247 million in 1995, with increases in net interest-earning assets
substantially offset by the effect of lower interest rates.

<PAGE>
 
  Principal transactions revenues increased 46% from the 1995 first quarter to
a record $982 million, as higher investor activity and market volatility led to
increases in virtually all trading products. Equities and equity derivatives
trading revenues, in the aggregate, were up 109% to $347 million. Trading
revenues from most equity products increased, due primarily to higher trading
volume and rising stock prices. International equities trading revenues, in
particular, benefited from the addition of Smith New Court trading activity.
Taxable fixed-income trading revenues rose 62% to $265 million due primarily to
higher revenues from non-U.S. governments and agencies, mortgage-backed
securities, and high-yield bonds. Non-U.S. governments and agencies trading
revenues advanced due to improved results from trading of Japanese Government
Bonds, as well as increased trading volume in certain Latin American emerging
markets as credit ratings improved and investors sought higher returns.
Mortgage-backed securities trading revenues increased due primarily to improved
liquidity and increased customer demand compared with the year-ago period.
Trading revenues from high-yield bonds were up due to lower interest rates and
improved credit ratings of certain issuers. Interest rate and currency swap
trading revenues increased 9% to $255 million due to higher trading revenues
from non-U.S. dollar-denominated transactions, partially offset by decreases in
revenues from U.S. dollar-denominated transactions. Foreign exchange and
commodities trading revenues, in the aggregate, rose 94% from the 1995 first
quarter to $40 million, as foreign exchange trading revenues continued to
benefit from the strengthening of the U.S. dollar versus other major
currencies. Municipal securities trading revenues declined 17% to $75 million,
primarily due to continued weak investor demand for tax-exempt investments.
 
  Investment banking revenues were $378 million, up 52% from $249 million in
the 1995 first quarter. Underwriting revenues increased 82%, benefiting from
strong levels of debt and equity underwriting industrywide, with higher fees
from convertibles, corporate bonds and preferred stock, equities, and high-
yield securities. Strategic services revenues were down slightly from a year
ago, but remained comparable to record 1995 levels, benefiting from continued
strong merger and acquisition activity.
 
  Asset management and portfolio service fees rose 20% in 1996 to a record $538
million from $448 million in the first quarter of 1995, primarily as a result
of strong inflows of client assets. Other revenues were $122 million, up 4%
from $117 million reported in the 1995 first quarter.
 
  Non-interest expenses were $2,590 million, up 27% from $2,041 million in the
year-ago period. Compensation and benefits expense, which represented
approximately 65% of non-interest expenses, increased 33% due primarily to
higher incentive and production-related compensation as well as a 6% increase
in the number of full-time employees, largely due to acquisitions. Compensation
and benefits expense as a percentage of net revenues was 51.8% in the first
quarter of 1996, compared with 52.5% in the 1995 first quarter.
 
  Occupancy costs increased 5% from the 1995 first quarter primarily due to
international growth. Other facilities-related costs, which include
communications and equipment rental expense and depreciation and amortization
expense, rose 16% primarily due to higher levels of business activity and
increased use of market data services, as well as higher depreciation expense
from the purchase of technology-related assets over the past year.
 
  Professional fees increased 32% from the year ago period, primarily as a
result of higher systems development costs related to upgrading technology and
processing capabilities. Advertising and market development expenses increased
33% from the 1995 first quarter. Increased international travel and higher
advertising and client promotion costs contributed to this advance. Brokerage,
clearing, and exchange fees rose 27% as a result of higher trading volume,
particularly in international markets. Other expenses increased 4% from 1995,
primarily due to goodwill amortization related to Smith New Court.
 
  Income tax expense totaled $262 million in the 1996 first quarter. The
effective tax rate in the 1996 first quarter was 39.0%, compared with 40.0% in
the first quarter of 1995. The decrease in the effective tax rate was primarily
attributable to increases in dividends qualifying for the Federal dividends
received deduction, lower state taxes, and expanded international business
activities.

                           DESCRIPTION OF THE STRYPES
 
  Each issue of STRYPES will be a series of Senior Debt Securities to be issued
under an indenture (the "Chemical Indenture"), dated as of April 1, 1983, as
amended and restated, between the Company and Chemical Bank (successor by
merger to Manufacturers Hanover Trust Company), as trustee (the "Trustee"), as
further amended and supplemented by a supplemental indenture to be entered into
by the Company and the Trustee relating to each series of STRYPES (the
"Supplemental Indenture") (the Chemical Indenture, as so amended and
supplemented by the Supplemental Indenture with respect to each series of
STRYPES, the "Indenture"). The following summary of certain provisions of the
Indenture does not purport to be complete and is qualified in its entirety by
reference to the Indenture. All capitalized terms not otherwise defined herein
have the meanings specified in the Indenture. Whenever defined terms of the
Indenture are referred to herein, such defined terms are incorporated by
reference herein.
 
GENERAL
 
  The Supplemental Indenture will provide that STRYPES of the related series
may be issued from time to time under the Indenture, up to a specified
aggregate issue price, upon satisfaction of certain conditions precedent. The
Supplemental Indenture will establish the terms of the related series of
STRYPES, including: (1) the issue price per STRYPES; (2) the date on which such
STRYPES will mature; (3) the consideration deliverable or payable with respect
to such STRYPES, whether at maturity or upon earlier acceleration, and the
formula or other method by which the amount of such consideration will be
determined; (4) the rate or rates per annum (which may be fixed or variable) at
which such STRYPES will bear interest, if any; (5) the dates on which such
interest, if any, will be payable; (6) the provisions for redemption of such
STRYPES, if any, the redemption price and any remarketing arrangements relating
thereto; (7) the sinking fund requirements, if any, with respect to such
STRYPES; (8) whether such STRYPES are denominated or provide for payment in
United States dollars or a foreign currency or units of two or more of such
foreign currencies; (9) whether and under what circumstances the Company will
pay additional amounts ("Additional Amounts") in respect of such STRYPES held
by a person who is not a U.S. person (as defined in the Prospectus Supplement,
as applicable) in respect of specified taxes, assessments or other governmental
charges and whether the Company has the option to redeem the affected STRYPES
rather than pay such Additional Amounts; (10) the title of the STRYPES and the
series of which such STRYPES shall be a part; and (11) the obligation of the
Company to pay and discharge such STRYPES at maturity by delivery of Underlying
Securities (or, cash with an equal value), the formula or other method by which
the amount of such Underlying Securities will be determined, and the terms and
conditions upon which such payment and discharge shall be effected. Reference
is made to the Prospectus Supplement for the terms of the STRYPES being offered
thereby.
 
  Under the Indenture, the Company will have the ability, in addition to the
ability to issue STRYPES with terms different from those of STRYPES previously
issued, to "reopen" a previous series of STRYPES and issue additional STRYPES
of such series.
 
  Issue price and interest, premium and Additional Amounts, if any, and
Underlying Securities will be payable or deliverable in the manner, at the
places and subject to the restrictions set forth in the Indenture, the STRYPES
and the Prospectus Supplement relating thereto, provided that payment of any
interest and any Additional Amounts may be made at the option of the Company by
check mailed to the holders of registered STRYPES at their registered
addresses.
 
  STRYPES may be presented for exchange, and registered STRYPES may be
presented for transfer, in the manner, at the places and subject to the
restrictions set forth in the Indenture, the STRYPES and the Prospectus
Supplement relating thereto. No service charge will be made for any transfer or
exchange of STRYPES, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.
 
                                       10
<PAGE>
 
RANKING
 
  The STRYPES will be unsecured obligations and will rank pari passu with all
other unsecured and unsubordinated indebtedness of the Company. Since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the holders of the STRYPES), to participate
in any distribution of the assets of any subsidiary upon its liquidation or
reorganization or otherwise is necessarily subject to the prior claims of
creditors of the subsidiary, except to the extent that claims of the Company
itself as a creditor of the subsidiary may be recognized. In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

  Upon issuance, each series of STRYPES will be represented by one or more
fully registered global securities (the "Global Notes"). Each such Global Note
will be deposited with, or on behalf of, The Depository Trust Company, as
Securities Depository (the "Securities Depository"), and registered in the name
of the Securities Depository or a nominee thereof. Unless and until it is
exchanged in whole or in part for STRYPES in definitive form under the limited
circumstances described below, no Global Note may be transferred except as a
whole by the Securities Depository to a nominee of such Securities Depository
or by a nominee of such Securities Depository to such Securities Depository or
another nominee of such Securities Depository or by such Securities Depository
or any such nominee to a successor of such Securities Depository or a nominee
of such successor.
 
  The Securities Depository has advised the Company as follows: The Securities
Depository is a limited-purpose trust company organized under the Banking Law
of the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Securities Exchange Act of 1934, as amended. The Securities Depository was
created to hold securities of its participants ("Participants") and to
facilitate the clearance and settlement of securities transactions among its
Participants in such securities through electronic book-entry changes in
accounts of the Participants, thereby eliminating the need for physical
movement of securities certificates. The Securities Depository's Participants
include securities brokers and dealers (including MLPF&S), banks, trust
companies, clearing corporations, and certain other organizations.
 
  The Securities Depository is owned by a number of Participants and by the New
York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National
Association of Securities Dealers, Inc. Access to the Securities Depository's
book-entry system is also available to others, such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship
with a Participant, either directly or indirectly ("Indirect Participants").
 
  Purchases of STRYPES must be made by or through Participants, which will
receive a credit on the records of the Securities Depository. The ownership
interest of each actual purchaser of each STRYPES ("Beneficial Owner") is in
turn to be recorded on the Participants' or Indirect Participants' records.
Beneficial Owners will not receive written confirmations from the Securities
Depository of their purchase, but Beneficial Owners are expected to receive
written confirmation providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interest in such Global Note will be shown on, and the transfer of
such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on
the records of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Notes.
 
  So long as the Securities Depository, or its nominee, is the registered owner
of a Global Note, the Securities Depository or its nominee, as the case may be,
will be considered the sole owner or holder of the STRYPES
 
                                       11
<PAGE>
 
represented by such Global Note for all purposes under the Indenture. Except as
provided below, Beneficial Owners in a Global Note will not be entitled to have
the STRYPES represented by such Global Notes registered in their names, will
not receive or be entitled to receive physical delivery of the STRYPES in
definitive form and will not be considered the owners or holders thereof under
the Indenture. Accordingly, each Person owning a beneficial interest in a
Global Note must rely on the procedures of the Securities Depository and, if
such Person is not a Participant, on the procedures of the Participant through
which such Person owns its interest, to exercise any rights of a holder under
the Indenture. The Company understands that under existing industry practices,
in the event that the Company requests any action of holders or that an owner
of a beneficial interest in such a Global Note desires to give or take any
action which a holder is entitled to give or take under the Indenture, the
Securities Depository would authorize the Participants holding the relevant
beneficial interests to give or take such action, and such Participants would
authorize Beneficial Owners owning through such Participants to give or take
such action or would otherwise act upon the instructions of Beneficial Owners.
Conveyance of notices and other communications by the Securities Depository to
Participants, by Participants to Indirect Participants, and by Participants and
Indirect Participants to Beneficial Owners will be governed by arrangements
among them, subject to any statutory or regulatory requirements as may be in
effect from time to time.
 
  Payment of any amount with respect to STRYPES registered in the name of the
Securities Depository or its nominee will be made to the Securities Depository
or its nominee, as the case may be, as the holder of the Global Notes
representing such STRYPES. None of the Company, the Trustee or any other agent
of the Company or agent of the Trustee will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests or for supervising or reviewing any records
relating to such beneficial ownership interests. The Company expects that the
Securities Depository, upon receipt of any payment in respect of a Global Note,
will credit the accounts of the Participants with payment in amounts
proportionate to their respective holdings of beneficial interest in such
Global Note as shown on the records of the Securities Depository. The Company
also expects that payments by Participants to Beneficial Owners will be
governed by standing customer instructions and customary practices, as is now
the case with securities held for the accounts of customers in bearer form or
registered in "street name", and will be the responsibility of such
Participants.
 
  If, with respect to a series of STRYPES, (x) the Securities Depository is at
any time unwilling or unable to continue as Securities Depository and a
successor depository is not appointed by the Company within 60 days, (y) the
Company executes and delivers to the Trustee a Company Order to the effect that
the Global Notes shall be exchangeable or (z) an Event of Default has occurred
and is continuing with respect to any STRYPES of that series, the Company will
issue STRYPES in definitive form in exchange for all of the Global Notes
representing the STRYPES of that series. Such definitive STRYPES shall be
registered in such name or names as the Securities Depository shall instruct
the Trustee. It is expected that such instructions may be based upon directions
received by the Securities Depository from Participants with respect to
ownership of beneficial interests in such Global Notes.
 
MERGER AND CONSOLIDATION
 
  The Company may consolidate or merge with or into any other corporation, and
the Company may sell, lease or convey all or substantially all of its assets to
any corporation, provided that (i) the corporation (if other than the Company)
formed by or resulting from any such consolidation or merger or which shall
have received such assets shall be a corporation organized and existing under
the laws of the United States of America or a state thereof and shall assume
the due and punctual delivery or payment of the Underlying Securities (or cash
with an equal value) in respect of, any interest and Additional Amounts on, and
any other amounts payable with respect to, the STRYPES of each series and the
due and punctual performance and observance of all of the covenants and
conditions of the Indenture to be performed or observed by the Company, and
(ii) the Company or such successor corporation, as the case may be, shall not
immediately thereafter be in default under the Indenture.
 
                                       12
<PAGE>
 
LIMITATIONS UPON LIENS
 
  The Indenture provides that the Company may not, and may not permit any
Subsidiary (defined in the Indenture as any corporation of which at the time of
determination the Company and/or one or more Subsidiaries owns or controls
directly or indirectly 50% of the shares of Voting Stock of such corporation)
to, create, assume, incur or permit to exist any indebtedness for borrowed
money secured by a pledge, lien or other encumbrance (except for certain liens
specifically permitted by the Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
STRYPES will be secured equally and ratably with such secured indebtedness.
 
LIMITATIONS ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS
BY, MLPF&S
 
  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to
any such transaction, MLPF&S remains a Controlled Subsidiary (defined in the
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company). In
addition, the Indenture provides that the Company may not permit MLPF&S to (i)
merge or consolidate, unless the surviving company is a Controlled Subsidiary,
or (ii) convey or transfer its properties and assets substantially as an
entirety, except to one or more Controlled Subsidiaries.
 
EVENTS OF DEFAULT
 
  Unless otherwise specified in a Prospectus Supplement, each of the following
will constitute an Event of Default under the Indenture with respect to each
series of STRYPES: (a) failure to pay and discharge the STRYPES of that series
with the Underlying Securities or, if the Company so elects, to pay an
equivalent amount in cash in lieu thereof when due; (b) failure to pay the
Redemption Price or any redemption premium with respect to any STRYPES of that
series when due; (c) failure to deposit any sinking fund payment, when and as
due by the terms of any STRYPES of that series; (d) failure to pay any interest
on or any Additional Amounts in respect of any STRYPES of that series when due,
continued for 30 days; (e) failure to perform any other covenant of the Company
contained in the Indenture for the benefit of that series or in the STRYPES of
that series, continued for 60 days after written notice has been given to the
Company by the Trustee, or to the Company and the Trustee by the holders of at
least 10% of the aggregate issue price of the Outstanding STRYPES of that
series, as provided in the Indenture; (f) certain events in bankruptcy,
insolvency or reorganization of the Company; and (g) any other Event of Default
provided with respect to STRYPES of that series.
 
  Unless otherwise specified in a Prospectus Supplement, if an Event of Default
(other than an Event of Default described in clause (f) of the immediately
preceding paragraph) with respect to the STRYPES of any series shall occur and
be continuing, either the Trustee or the holders of at least 25% of the
aggregate issue price of the Outstanding STRYPES of that series by notice as
provided in the Indenture may declare an amount equal to the aggregate issue
price of all the STRYPES of that series and the interest accrued thereon and
Additional Amounts payable in respect thereof, if any, to be immediately due
and payable in cash. If an Event of Default described in said clause (f) shall
occur, an amount equal to the aggregate issue price of all the STRYPES of that
series and the interest accrued thereon and Additional Amounts payable in
respect thereof, if any, will become immediately due and payable in cash
without any declaration or other action on the part of the Trustee or any
holder. After such acceleration, but before a judgment or decree based on
acceleration, the holders of a majority of the aggregate issue price of the
Outstanding STRYPES of that series may, under certain circumstances, rescind
and annul such acceleration if all Events of Default, other than the non-
payment of the amount equal to the aggregate issue price of all the STRYPES of
that series due by reason of such acceleration, have been cured or waived as
provided in the Indenture. See "Modification and Waiver" below.
 
                                       13
<PAGE>
 
  Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default shall occur and be continuing, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the holders of STRYPES of any
series, unless such holders of that series shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred by it in compliance with such request or direction.
Subject to such provisions for the indemnification of the Trustee, the holders
of a majority of the aggregate issue price of the STRYPES of any series will
have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee with respect to the STRYPES of that series.
 
  The Company will be required to furnish to the Trustee annually a statement
by certain of its officers as to whether or not the Company, to their
knowledge, is in default in the fulfillment of any of its obligations under the
Indenture and, if so, specifying all such known defaults.
 
  The STRYPES and other series of Senior Debt Securities issued under the
Indenture will not have the benefit of any cross-default provisions with other
indebtedness of the Company.
 
MODIFICATION AND WAIVER
 
  Unless otherwise specified in a Prospectus Supplement, modifications of and
amendments to the Indenture affecting a series of STRYPES may be made by the
Company and the Trustee with the consent of the holders of 66 2/3% of the
aggregate issue price of the Outstanding STRYPES of such series; provided,
however, that no such modification or amendment may, without the consent of the
holder of each Outstanding STRYPES of such series affected thereby, (a) change
the Maturity Date or the Stated Maturity of any installment of interest or
Additional Amounts on any STRYPES or any premium payable on the redemption
thereof, or change the Redemption Price, (b) reduce the amount of Underlying
Securities payable with respect to any STRYPES (or reduce the amount of cash
payable in lieu thereof), (c) reduce the amount of interest or Additional
Amounts payable on any STRYPES or reduce the amount of cash payable with
respect to any STRYPES upon acceleration of the maturity thereof, (d) change
the place or currency of payment of interest or Additional Amounts on, or any
amount of cash payable with respect to, any STRYPES, (e) impair the right to
institute suit for the enforcement of any payment on or with respect to any
STRYPES, including the payment of Underlying Securities with respect to any
STRYPES, (f) reduce the percentage of the aggregate issue price of Outstanding
STRYPES of such series, the consent of whose holders is required to modify or
amend the Indenture, (g) reduce the percentage of the aggregate issue price of
Outstanding STRYPES of such series necessary for waiver of compliance with
certain provisions of the Indenture or for waiver of certain defaults or (h)
modify such provisions with respect to modification and waiver. Except as
provided in the Indenture, no modification of or amendment to the Indenture may
adversely affect the rights of a holder of any other Senior Debt Security
without the consent of such holder.
 
  The holders of a majority of the aggregate issue price of each series of
STRYPES may waive compliance by the Company with certain restrictive provisions
of the Indenture. The holders of a majority of the aggregate issue price of
each series of STRYPES may waive any past default under the Indenture, except a
default in the payment of the Underlying Securities with respect to any STRYPES
of that series, or of cash payable in lieu thereof, or in the payment of any
premium, interest or Additional Amounts on any STRYPES of that series for which
payment had not been subsequently made or in respect of a covenant and
provision of the Indenture which cannot be modified or amended without the
consent of the holder of each Outstanding STRYPES of such series affected.
 
GOVERNING LAW
 
  The Indenture and the STRYPES will be governed by, and construed in
accordance with, the laws of the State of New York.

                              PLAN OF DISTRIBUTION
 
  The Company may sell STRYPES to the public through MLPF&S. The accompanying
Prospectus Supplement describes the terms of the STRYPES offered thereby,
including the public offering or purchase price, any discounts and commissions
to be allowed or paid to MLPF&S, all other items constituting underwriting
compensation, the discounts and commissions to be allowed or paid to dealers,
if any, and the exchanges, if any, on which the STRYPES will be listed. Only
MLPF&S will act as an underwriter in connection with the STRYPES. Under certain
circumstances, the Company may repurchase STRYPES and reoffer them to the
public as set forth above. The Company may also arrange for repurchases and
resales of such STRYPES by dealers.
 
  The underwriting of STRYPES will conform to the requirements set forth in the
applicable sections of Schedule E to the By-Laws of the National Association of
Securities Dealers, Inc.

  With respect to unaudited interim financial information for the periods

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 of the General Corporation Law of the State of Delaware, as
amended, provides that under certain circumstances a corporation may indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that such
person is or was a director, officer, employee or agent of the corporation or
is or was serving at its request in such capacity in another corporation or
business association, against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by such
person in connection with such action, suit or proceeding if such person acted
in good faith and in a manner such person reasonably believed to be in or not
opposed to the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe such person's
conduct was unlawful.
 
  Article XIII, Section 2 of the Restated Certificate of Incorporation of the
Registrant provides in effect that, subject to certain limited exceptions, the
Registrant shall indemnify its directors and officers to the extent authorized
or permitted by the General Corporation Law of the State of Delaware.
 
  The Form of Underwriting Agreement filed as Exhibit 1(a) provides for the
indemnification of the Registrant, its controlling persons, its directors and
certain of its officers by the Underwriter against certain liabilities,
including liabilities under the Securities Act of 1933, as amended. The Form of
Registration Agreement filed as Exhibit 1(b) provides for the indemnification
of the Registrant and its controlling persons by IMC Global Inc. against
certain liabilities, including liabilities under the Securities Act of 1933, as
amended.
 
  The directors and officers of the Registrant are insured under policies of
insurance maintained by the Registrant, subject to the limits of the policies,
against certain losses arising from any claim made against them by reason of
being or having been such directors or officers. In addition, the Registrant
has entered into contracts with all of its directors providing for
indemnification of such persons by the Registrant to the full extent authorized
or permitted by law, subject to certain limited exceptions.

     The STRYPES will be payable at maturity by delivery of the Maturity
Consideration (as defined in the Supplemental Indenture) subject to the
Company's option to deliver cash with an equal value.  The Company, IMC and the
Underwriter are concurrently entering into an agreement dated the date hereof
(the "Registration Agreement") relating to the registration of shares of common
stock, par value $1.00 per share (the "IMC Common Stock"), of IMC Global Inc., a
Delaware corporation ("IMC"), Common Stock that may be deliverable by the
Company pursuant to the STRYPES.

     The Company understands that the Underwriter proposes to make a public
offering of the Securities as soon as the Underwriter deems advisable after this
Agreement has been executed and delivered.

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 33-65135) for the
registration of debt securities, including the Securities, and warrants under
the Securities Act of 1933, as amended (the "1933 Act"), and the offering
thereof from time to time in accordance with Rule 415 of the rules and
regulations of the Commission under the 1933 Act (the "1933 Act Regulations"),
and the Company has filed post-effective amendment no. 3 and post-effective
amendment no. 5 thereto, including a preliminary prospectus and preliminary
prospectus supplement relating to the offering of the Securities.  Promptly
after execution and delivery of this Agreement, the Company will either (i)
prepare and file a prospectus and prospectus supplement in accordance with the
provisions of Rule 430A ("Rule 430A") of the 1933 Act Regulations and paragraph
(b) of Rule 424 ("Rule 424(b)") of the 1933 Act Regulations or (ii) if the
Company has elected to rely upon Rule 434 ("Rule 434") of the 1933 Act
Regulations, prepare and file a term sheet (an "ML&Co. Term Sheet") in
accordance with the provisions of Rule 434 and Rule 424(b).  The information
included in such prospectus and prospectus supplement or in such ML&Co. Term
Sheet, as the case may be, that was omitted from such registration statement (as

     conflict (if the subject of any unfavorable decision, ruling or finding) or
     invalidity or inadequacy, singly or in the aggregate, would result in a

     is and will be in compliance with, the provisions of that certain Florida
     act relating to disclosure of doing business with Cuba, codified as Section
     517.075 of the Florida statutes, and the rules and regulation thereunder
     (collectively, the "Cuba Act") or is exempt therefrom.

     (b) Representations and Warranties by GVI.  GVI represents and warrants to
each of the Company and the Underwriter as of the date hereof, as of the Closing
Time referred to in Section 2(c) hereof, and as of each Date of Delivery (if
any) referred to in Section 2(b) hereof, and agrees with each of the Company and
the Underwriter, as follows:

          (i)  Good Standing of GVI. GVI has been duly organized and is validly
               --------------------                                            
     existing as a corporation in good standing under the laws of the State of
     Delaware and has corporate power and authority to enter into and perform
     its obligations under this Agreement and the Purchase Agreement.

          (ii)  Delivery of IMC Common Stock.  At the date hereof, GVI is the
                ----------------------------                                 
     sole registered owner of and has all rights in and to at least 6,510,268
     shares of IMC  Common Stock, free and clear of any security interest,
     mortgage, pledge, lien, encumbrance, claim or equity (except for the
     security interest created under or pursuant to [describe existing bridge
     loan], which will have been released at the Closing Time, and such as may
     be created under or pursuant to that certain [describe new loan
     agreement]).  If immediately prior to maturity of the Securities GVI
     delivers to the Company shares of IMC Common Stock pursuant to the Purchase
     Agreement, upon delivery by GVI to the ML&Co. Subsidiary of such shares of
     IMC Common Stock pursuant to the Purchase Agreement, the ML&Co. Subsidiary
     will be the sole registered owner of the shares of IMC Common Stock so
     delivered and, assuming the ML&Co. Subsidiary purchased for value in good
     faith and without notice of any adverse claim, the ML&Co. Subsidiary will
     have acquired all rights in and to such shares of IMC Common Stock, free
     and clear of any security interest, mortgage, pledge, lien, encumbrance,
     claim or equity.  The delivery of shares of IMC Common Stock to the ML&Co.
     Subsidiary at maturity of the Securities in accordance with the Purchase
     Agreement is not, and at the time of delivery of such shares will not be,
     subject to any right of first refusal or similar rights of any person
     pursuant to any contract to which GVI or any of its subsidiaries is a party
     or by which any of them is bound.

          (iii)  Authorization of Agreement.  This Agreement has been duly
                 --------------------------                               
     authorized, executed and delivered by GVI.

          (iv)  Authorization of the Purchase Agreement. The Purchase Agreement
                ---------------------------------------                        
     has been duly authorized by GVI and, at the Closing Time, will have been
     duly executed and delivered by GVI and (assuming the due authorization,
     execution and delivery by the Company and the ML&Co. Subsidiary) will
     constitute a valid and binding agreement of GVI, enforceable against GVI in
     accordance with its terms, except as the enforcement thereof may be limited
     by bankruptcy, insolvency (including, without limitation, all laws relating
     to fraudulent transfers), reorganization, moratorium or similar laws
     affecting enforcement of creditors' rights generally and except as
     enforcement thereof is subject

                                       11
<PAGE>
 
     to general principles of equity (regardless of whether enforcement is
     considered in a proceeding in equity or at law).  Amounts received by GVI
     at Closing Time and at each Date of Delivery, if any, pursuant to the
     Purchase Agreement will not be used by GVI for the purpose, whether
     immediate, incidental or ultimate, of buying or carrying a margin stock, as
     such terms are defined in Regulation G promulgated by the Board of
     Governors of the Federal Reserve System.

          (v)  Absence of Defaults and Conflicts. The execution, delivery and
               ---------------------------------                             
     performance by GVI of this Agreement and the Purchase Agreement and the
     consummation by GVI of the transactions contemplated herein and therein and
     compliance by GVI with its obligations hereunder and thereunder have been
     duly authorized by all necessary corporate action and do not and will not,
     whether with or without the giving of notice or passage of time or both,
     conflict with or constitute a breach of, or default or GVI Repayment Event
     (as defined below) under, or result in the creation or imposition of any
     lien, charge or encumbrance upon any property or assets of GVI or any of
     its subsidiaries pursuant to, any contract, indenture, mortgage, deed of
     trust, loan or credit agreement, note, lease or any other agreement or
     instrument to which GVI or any of its subsidiaries is a party or by which
     it or any of them may be bound, or to which any of the property or assets
     of GVI or any of its subsidiaries is subject (except for such conflicts,
     breaches or defaults or liens, charges or encumbrances that would not,
     singly or in the aggregate, materially and adversely affect the ability of
     GVI to perform its obligations under this Agreement or the Purchase
     Agreement), nor will such action result in any violation of the provisions
     of the charter or by-laws of GVI or any of its subsidiaries, or any
     applicable law, statute, rule or regulation of any government or government
     instrumentality having jurisdiction over GVI or any of its subsidiaries or
     any of their assets, properties or operations (other than any state
     securities or "blue sky" law, statute, rule or regulation, as to which no
     representation and warranty is made), or any applicable judgment, order,
     writ or decree of any government, government instrumentality or domestic
     court having jurisdiction over GVI or any of its subsidiaries or any of
     their assets, properties or operations (except in all cases for such
     violations that would not, singly or in the aggregate, materially and
     adversely affect the ability of GVI to perform its obligations under this
     Agreement or the Purchase Agreement).  As used herein, a "GVI Repayment
     Event" means any event or condition which gives the holder of any note,
     debenture or other evidence of indebtedness (or any person acting on such
     holder's behalf) the right to require the repurchase, redemption or
     repayment of all or a portion of such indebtedness by GVI or any of its
     subsidiaries.

          (vi)  Absence of Further Requirements. No filing with, or
                -------------------------------                    
     authorization, approval, consent, license, order, registration,
     qualification or decree of, any court or governmental authority or agency
     is necessary or required for the execution, delivery or performance by GVI
     of this Agreement or the Purchase Agreement or the consummation by GVI of
     the transactions contemplated by this Agreement or the Purchase Agreement,
     except such as have been already obtained or as may be required under the
     1933 Act or the 1933 Act Regulations or state securities laws.

          (vii)  IMC Registration Statement and Prospectus.  The IMC
                 -----------------------------------------          
     Registration Statement, any IMC Rule 462(b) Registration Statement or any
     post-effective amendments thereto, at the respective times the IMC
     Registration Statement, any IMC Rule 462(b) Registration Statement or any
     post-effective amendments thereto became effective, did not contain an
     untrue statement of a material fact or omit to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading.  The IMC Prospectus or any amendment or supplement thereto,
     at the time the IMC Prospectus was issued, at the time any such amended or
     supplemented prospectus was issued or at the Closing Time (and, if any
     Option Securities are purchased, at the Date of Delivery), did not and will
     not include an untrue statement of a material fact and did not and will not
     omit to state a material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading.  The representations and warranties in this subsection shall
     apply only to statements in or omissions from the IMC Registration
     Statement (or any amendment thereto) or IMC Prospectus (or any amendment or
     supplement thereto) made in reliance upon and in conformity with
     information furnished to IMC in writing by GVI expressly for use in the IMC
     Registration Statement (or any amendment thereto) or IMC Prospectus (or any
     amendment or supplement thereto).

     (c) Officer's Certificates.  Any certificate signed by any officer of the
Company or any of its subsidiaries delivered to the Underwriter shall be deemed
a representation and warranty by the Company to the Underwriter as to the
matters covered thereby.  Any certificate signed by any officer of GVI or any of
its subsidiaries delivered to the Underwriter or the Company shall be deemed a
representation and warranty by GVI to the Underwriter or the Company, as the
case may be, as to the matters covered thereby.

Underwriter is then exercising the option and the time and date of payment and

as follows:

          (i) Compliance with Securities Regulations and Commission Requests.
     The Company, subject to Section 3(a)(ii), will comply with the requirements
     of Rule 430A or Rule 434, as applicable, and will notify the Underwriter
     immediately, and confirm the notice in writing, (A) when any post-effective
     amendment to the ML&Co. Registration Statement shall become effective, or
     any supplement to the ML&Co. Prospectus or any amended ML&Co. Prospectus
     shall have been filed, (B) of the receipt of any comments from the
     Commission, (C) of any request by the Commission for any amendment to the
     ML&Co. Registration Statement or any amendment or supplement to the ML&Co.
     Prospectus or for additional information, and (D) of the issuance by the
     Commission of any stop order suspending the effectiveness of the ML&Co.
     Registration Statement or of any order preventing or suspending the use of
     any ML&Co. preliminary prospectus, or of the suspension of the
     qualification of the Securities for offering or sale in any jurisdiction,
     or of the initiation or threatening of any proceedings for any of such
     purposes.  The Company will promptly effect the filings necessary pursuant
     to Rule 424(b) and will take such steps as it deems necessary to ascertain
     promptly whether the form of prospectus transmitted for filing under Rule
     424(b) was received for filing by the

                                       14
<PAGE>
 
     Commission and, in the event that it was not, it will promptly file such
     prospectus.  The Company will make every reasonable effort to prevent the
     issuance of any stop order and, if any stop order is issued, to obtain the
     lifting thereof at the earliest possible moment.

          (ii) Filing of Amendments.   The Company will give the Underwriter
     notice of its intention to file or prepare any amendment to the ML&Co.
     Registration Statement (including any filing under Rule 462(b)), any ML&Co.
     Term Sheet or any amendment, supplement or revision to either the
     prospectus relating to the offering of the Securities included in the
     ML&Co. Registration Statement at the time it became effective or to the
     ML&Co. Prospectus, whether pursuant to the 1933 Act, the 1934 Act or
     otherwise, will furnish the Underwriter with copies of any such documents a
     reasonable amount of time prior to such proposed filing or use, as the case
     may be, and will not file or use any such document to which the Underwriter
     or counsel for the Underwriter shall reasonably object.

          (iii)  Delivery of ML&Co. Registration Statements.  The Company has
     furnished or will deliver to the Underwriter, without charge, signed copies
     of the ML&Co. Registration Statement as originally filed and of each
     amendment thereto (including exhibits filed therewith or incorporated by
     reference therein and documents incorporated or deemed to be incorporated
     by reference therein) and signed copies of all consents and certificates of
     experts.  If applicable, the copies of the ML&Co. Registration Statement
     and each amendment thereto furnished to the Underwriter will be identical
     to the electronically transmitted copies thereof filed with the Commission
     pursuant to EDGAR, except to the extent permitted by Regulation S-T.

          (iv) Delivery of ML&Co. Prospectuses.  The Company has delivered to
     the Underwriter, without charge, as many copies of each ML&Co. preliminary
     prospectus as the Underwriter reasonably requested, and the Company hereby
     consents to the use of such copies for purposes permitted by the 1933 Act.
     The Company will furnish to the Underwriter, without charge, during the
     period when the ML&Co. Prospectus is required to be delivered under the
     1933 Act or the 1934 Act, such number of copies of the ML&Co. Prospectus
     (as amended or supplemented) as the Underwriter may reasonably request.  If
     applicable, the ML&Co. Prospectus and any amendments or supplements thereto
     furnished to the Underwriter will be identical to the electronically
     transmitted copies thereof filed with the Commission pursuant to EDGAR,
     except to the extent permitted by Regulation S-T.

          (v) Continued Compliance with Securities Laws.  The Company will
     comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act and
     the 1934 Act Regulations so as to permit the completion of the distribution
     of the Securities as contemplated in this Agreement and in the ML&Co.
     Prospectus.  If at any time when a prospectus is required by the 1933 Act
     to be delivered in connection with sales of the Securities, any event shall
     occur or condition shall exist as a result of which it is necessary, in the
     opinion of counsel for the Underwriter or for the Company, to amend the
     ML&Co. Registration Statement or amend or supplement the ML&Co. Prospectus

                                       15
<PAGE>
 
     in order that the ML&Co. Prospectus will not include any untrue statements
     of a material fact or omit to state a material fact necessary in order to
     make the statements therein not misleading in the light of the
     circumstances existing at the time it is delivered to a purchaser, or if it
     shall be necessary, in the opinion of either such counsel, at any such time
     to amend the ML&Co. Registration Statement or amend or supplement the
     ML&Co. Prospectus in order to comply with the requirements of the 1933 Act
     or the 1933 Act Regulations, the Company will promptly prepare and file
     with the Commission, subject to Section 3(a)(ii), such amendment or
     supplement as may be necessary to correct such statement or omission or to
     make the ML&Co. Registration Statement or the ML&Co. Prospectus comply with
     such requirements, and the Company will furnish to the Underwriter such
     number of copies of such amendment or supplement as the Underwriter may
     reasonably request.

          (vi) Blue Sky Qualifications.  The Company will use its best efforts,
     in cooperation with the Underwriter, to qualify the Securities for offering
     and sale under the applicable securities laws of such states and other
     jurisdictions of the United States as the Underwriter may designate and to
     maintain such qualifications in effect for a period of not less than one
     year from the later of the effective date of the ML&Co. Registration
     Statement and any ML&Co. Rule 462(b) Registration Statement; provided,
     however, that the Company shall not be obligated to file any general
     consent to service of process or to qualify as a foreign corporation or as
     a dealer in securities in any jurisdiction in which it is not so qualified
     or to subject itself to taxation in respect of doing business in any
     jurisdiction in which it is not otherwise so subject.  In each jurisdiction
     in which the Securities have been so qualified, the Company will file such
     statements and reports as may be required by the laws of such jurisdiction
     to continue such qualification in effect for a period of not less than one
     year from the effective date of the ML&Co. Registration Statement and any
     ML&Co. Rule 462(b) Registration Statement.

          (vii)  Rule 158.  The Company will timely file such reports pursuant
     to the 1934 Act as are necessary in order to make generally available to
     its securityholders as soon as practicable an earnings statement for the
     purposes of, and to provide the benefits contemplated by, the last
     paragraph of Section 11(a) of the 1933 Act.

          (viii)  Use of Proceeds.  The Company will use the net proceeds
     received by it from the sale of the Securities in the manner specified in
     the ML&Co. Prospectus under "Supplemental Use of Proceeds."

          (ix) Listing.  The Company will use its best efforts to effect the
     listing of the Securities on the New York Stock Exchange.

          (x) Reporting Requirements.  The Company, during the period when the
     ML&Co. Prospectus is required to be delivered under the 1933 Act or the
     1934 Act, will file all documents required to be filed with the Commission
     pursuant to the 1934 Act within the time periods required by the 1934 Act
     and the 1934 Act Regulations.

          hereof.

     (c) Termination of Agreement.  If any condition specified in subsection (a)
of this Section shall not have been fulfilled when and as required to be

obligations of the Underwriter to purchase the relevant Option Securities, may
be terminated by the Underwriter by notice to the Company and GVI at any time at
or prior to Closing Time or such Date of Delivery, as the case may be, and such
termination shall be without liability of any party to any other party except as

Securities, may be terminated by the Company by notice to the Underwriter and
GVI at any time at or prior to Closing Time or such Date of Delivery, as the

other party except as provided in Section 4 and except that Sections 1, 6, 7 and
8 shall survive any such termination and remain in full force and effect.

     SECTION 6.  Indemnification.
                 --------------- 

     (a) Indemnification of the Underwriter by the Company.  The Company agrees
to indemnify and hold harmless the Underwriter and each person, if any, who
controls the Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act as follows:

          (i)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material

                                       24
<PAGE>
 
     fact contained in the ML&Co. Registration Statement (or any amendment
     thereto), including the Rule 430A Information and the Rule 434 Information,
     if applicable, or the omission or alleged omission therefrom of a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading or arising out of any untrue statement or alleged
     untrue statement of a material fact contained in any ML&Co. preliminary
     prospectus or the ML&Co. Prospectus (or any amendment or supplement
     thereto), or the omission or alleged omission therefrom of a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading;

          (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, referred to under (i) above; provided
     that (subject to Section 6(e) below) any such settlement is effected with
     the written consent of the Company; and

          (iii)  against any and all expense whatsoever, as incurred (including
     the fees and disbursements of counsel chosen by the Underwriter),
     reasonably incurred in investigating, preparing or defending against any
     litigation, or any investigation or proceeding by any governmental agency
     or body, commenced or threatened, or any claim whatsoever based upon any
     such untrue statement or omission, or any such alleged untrue statement or
     omission, referred to under (i) above, to the extent that any such expense
     is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by the
Underwriter expressly for use in the ML&Co. Registration Statement (or any
amendment thereto), including the Rule 430A Information and the Rule 434
Information, if applicable, or any ML&Co. preliminary prospectus or the ML&Co.
Prospectus (or any amendment or supplement thereto).

     Insofar as this indemnity agreement may permit indemnification for
liabilities under the 1933 Act of any person who controls an underwriter within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and who,
at the date of this Agreement, is a director or officer of the Company or
controls the Company within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act, such indemnity agreement is subject to the undertaking of
the Company in the ML&Co. Registration Statement under Item 17 thereof.

     (b) Indemnification of the Underwriter and the Company by GVI.  GVI agrees
to indemnify and hold harmless (1) the Underwriter and each person, if any, who
controls the Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act and (2) the Company and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act, as follows:

                                       25
<PAGE>
 
     (i)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in the IMC Registration
     Statement (or any amendment thereto), or the omission or alleged omission
     therefrom of a material fact required to be stated therein or necessary to
     make the statements therein not misleading or arising out of any untrue
     statement or alleged untrue statement of a material fact contained in any
     IMC preliminary prospectus or the IMC Prospectus (or any amendment or
     supplement thereto), or the omission or alleged omission therefrom of a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

          (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, referred to under (i) above; provided
     that (subject to Section 6(e) below) any such settlement is effected with
     the written consent of GVI; and

          (iii)  against any and all expense whatsoever, as incurred (including
     the fees and disbursements of counsel chosen by the Underwriter or the
     Company, as the case may be), reasonably incurred in investigating,
     preparing or defending against any litigation, or any investigation or
     proceeding by any governmental agency or body, commenced or threatened, or
     any claim whatsoever based upon any such untrue statement or omission, or
     any such alleged untrue statement or omission, referred to under (i) above,
     to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall apply only with respect
to untrue statements or omissions, or alleged untrue statements or omissions,
made in the IMC Registration Statement (or any amendment thereto) or any IMC
preliminary prospectus or the IMC Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished
to IMC by GVI expressly for use in the IMC Registration Statement (or any
amendment thereto) or any IMC preliminary prospectus or the IMC Prospectus (or
any amendment or supplement thereto).

     (c) Indemnification of the Company, Directors and Officers.  The
Underwriter agrees to indemnify and hold harmless the Company, its directors,
each of its officers who signed the ML&Co. Registration Statement, and each
person, if any, who controls the Company within the meaning of Section 15 of the
1933 Act or Section 20 of the 1934 Act against any and all loss, liability,
claim, damage and expense described in the indemnity contained in subsection (a)
of this Section, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the ML&Co.
Registration Statement (or any amendment thereto), including the Rule 430A
Information and the Rule 434 Information, if applicable, or any ML&Co.
preliminary prospectus or the ML&Co. Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished
to the Company by the Underwriter expressly for use in the ML&Co. Registration
Statement (or any

                                       26
<PAGE>
 
amendment thereto) or such ML&Co. preliminary prospectus or the ML&Co.
Prospectus (or any amendment or supplement thereto).

     (d) Actions against Parties; Notification.  Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder which it may have otherwise than
on account of this indemnity agreement.  In the case of parties indemnified
pursuant to Section 6(a) or clause (1) of Section 6(b) above, counsel to the
indemnified parties shall be selected by the Underwriter, and, in the case of
parties indemnified pursuant to clause (2) of Section 6(b) or Section 6(c)
above, counsel to the indemnified parties shall be selected by the Company.  An
indemnifying party may participate at its own expense in the defense of any such
action; provided, however, that counsel to the indemnifying party shall not
(except with the consent of the indemnified party) also be counsel to the
indemnified party.  In no event shall the indemnifying parties be liable for
fees and expenses of more than one counsel (in addition to any local counsel)
separate from their own counsel for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances.  No
indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with
respect to any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever in
respect of which indemnification or contribution could be sought under this
Section 6 or Section 7 hereof (whether or not the indemnified parties are actual
or potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.

     (e) Settlement without Consent if Failure to Reimburse.  If at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(ii) and 6(b)(ii) effected without its written consent if (i) such
settlement is entered into more than 45 days after receipt by such indemnifying
party of the aforesaid request, (ii) such indemnifying party shall have received
notice of the terms of such settlement at least 30 days prior to such settlement
being entered into and (iii) such indemnifying party shall not have reimbursed
such indemnified party in accordance with such request prior to the date of such
settlement.

     SECTION 7.  Contribution.
                 ------------ 

     (a) If the indemnification provided for in Sections 6(a) and 6(c) is for
any reason unavailable to or insufficient to hold harmless an indemnified party
in respect of any losses, liabilities, claims, damages or expenses referred to
therein, then the Company and the Underwriter shall contribute to the aggregate
amount of such losses, liabilities, claims, damages and expenses incurred by
such indemnified party, as incurred, (i) in such proportion as is appropriate to
reflect the relative benefits received by the Company on the one hand and the

                                       27
<PAGE>
 
Underwriter on the other hand from the offering of the Securities pursuant to
this Agreement or (ii) if the allocation provided by clause (i) is not permitted
by applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company on the one hand and of the Underwriter on the other hand in
connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.  The relative benefits received by the Company on the
one hand and the Underwriter on the other hand in connection with the offering
of the Securities pursuant to this Agreement shall be deemed to be in the same
respective proportions as the total net proceeds from the offering of the
Securities pursuant to this Agreement (before deducting expenses) received by
the Company and the total underwriting discount received by the Underwriter, in
each case as set forth on the cover of the ML&Co. Prospectus, or, if Rule 434 is
used, the corresponding location on the ML&Co. Term Sheet, bear to the aggregate
initial public offering price of the Securities as set forth on such cover.  The
relative fault of the Company on the one hand and the Underwriter on the other
hand shall be determined by reference to, among other things, whether any such
untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information supplied by the Company
or by the Underwriter and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

     Notwithstanding the provisions of this Section 7(a), the Underwriter shall
not be required to contribute any amount in excess of the amount by which the
total price at which the Securities underwritten by it and distributed to the
public were offered to the public exceeds the amount of any damages which the
Underwriter has otherwise been required to pay by reason of any such untrue or
alleged untrue statement or omission or alleged omission.

     The Company and the Underwriter agree that it would not be just and
equitable if contribution pursuant to this Section 7(a) were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 7(a).  The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 7(a) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 7(a), each person, if any, who controls the
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as the Underwriter, and
each director of the Company, each officer of the Company who signed the ML&Co.
Registration Statement, and each person, if any, who controls the Company within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall
have the same rights to contribution as the Company.

                                       28
<PAGE>
 
     (b) If the indemnification provided for in Section 6(b) hereof is for any
reason unavailable to or insufficient to hold harmless an indemnified party in
respect of any losses, liabilities, claims, damages or expenses referred to
therein, then GVI on the one hand and the Underwriter and the Company on the
other hand shall contribute to the aggregate amount of such losses, liabilities,
claims, damages and expenses incurred by such indemnified party, as incurred,
(i) in such proportion as is appropriate to reflect the relative benefits
received by GVI on the one hand and by the Underwriter and the Company on the
other hand from the offering of the Securities pursuant to this Agreement or
(ii) if the allocation provided by clause (i) is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of GVI on
the one hand and of the Underwriter and the Company on the other hand in
connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.  The relative benefits received from the offering of
the Securities pursuant to this Agreement shall be deemed to be such that the
Underwriter and the Company shall be responsible for that portion of the
aggregate amount of such losses, liabilities, claims, damages and expenses
represented by the percentage that the total underwriting discount received by
the Underwriter, as set forth on the cover of the ML&Co. Prospectus, or, if Rule
434 is used, the corresponding location on the ML&Co. Term Sheet, bears to the
aggregate initial public offering price of the Securities as set forth on such
cover and GVI shall be responsible for the balance.  The relative fault of GVI
on the one hand and the Underwriter and the Company on the other hand shall be
determined by reference to, among other things, whether any such untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by GVI on the one hand or
by the Underwriter or the Company on the other hand and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

     Notwithstanding the provisions of this Section 7(b), the Underwriter and
the Company shall not be required to contribute any amount in excess of the
amount by which the total price at which the Securities underwritten by the
Underwriter and distributed to the public were offered to the public exceeds the
amount of any damages which the Underwriter and the Company have otherwise been
required to pay by reason of any such untrue or alleged untrue statement or
omission or alleged omission.

     GVI, the Underwriter and the Company agree that it would not be just and
equitable if contribution pursuant to this Section 7(b) were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 7(b).  The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 7(b) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

                                       29
<PAGE>
 
     For purposes of this Section 7(b), each person, if any, who controls the
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as the Underwriter, and
each person, if any, who controls the Company within the meaning of Section 15
of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to
contribution as the Company.

     SECTION 8.  Representations, Warranties and Agreements to Survive Delivery.
                 -------------------------------------------------------------- 
All representations, warranties and agreements contained in this Agreement or in
certificates of officers of the Company, IMC or GVI submitted pursuant hereto,
shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of the Underwriter or controlling person, or
by or on behalf of the Company or GVI, and shall survive delivery of the
Securities to the Underwriter.

     SECTION 9.  Termination of Agreement.
                 ------------------------ 

     (a) Termination; General.  The Underwriter may terminate this Agreement, by
notice to the Company and GVI, at any time at or prior to Closing Time (i) if
there has been, since the time of execution of this Agreement or since the
respective dates as of which information is given in the ML&Co. Prospectus, any
material adverse change in the condition, financial or otherwise, or in the
earnings, business affairs or business prospects of the Company and its
subsidiaries considered as one enterprise, whether or not arising in the
ordinary course of business, or (ii) if there has been, since the time of
execution of this Agreement, or since the respective dates as of which
information is given in the IMC Prospectus, any material adverse change in the
condition, financial or otherwise, or in the earnings, business affairs or
business prospects of IMC and its subsidiaries considered as one enterprise,
whether or not arising in the ordinary course of business, or (iii) if there has
occurred any material adverse change in the financial markets in the United
States, any outbreak of hostilities or escalation thereof or other calamity or
crisis or any change or development involving a prospective change in national
or international political, financial or economic conditions, in each case the
effect of which is such as to make it, in the judgment of the Underwriter,
impracticable to market the Securities or to enforce contracts for the sale of
the Securities, or (iv) if trading in any securities of the Company or in the
IMC Common Stock has been suspended or limited by the Commission or the New York
Stock Exchange, or if trading generally on the American Stock Exchange or the
New York Stock Exchange or in the Nasdaq National Market has been suspended or
limited, or minimum or maximum prices for trading have been fixed, or maximum
ranges for prices have been required, by any of said exchanges or by such system
or by order of the Commission, the NASD or any other governmental authority, or
(v) if a banking moratorium has been declared by either federal or New York
authorities.

     (b) Liabilities.  If this Agreement is terminated pursuant to this Section,
such termination shall be without liability of any party to any other party
except as provided in Section 4 hereof, and provided further that Sections 1, 6,
7 and 8 shall survive such termination and remain in full force and effect.

     SECTION 10. Notices.  All notices and other communications hereunder shall
                 -------

be binding upon each of the Underwriter, the Company and GVI and their
respective successors.  Nothing expressed or mentioned in this Agreement is
intended or shall be construed to give any person, firm or corporation, other

  business and is in good standing in each jurisdiction in which such

  or encumbrance upon any property or assets of the Company or any subsidiary

  agreement, note, lease or any other agreement or instrument, known to us, to
  which the Company or any subsidiary is a party or by which it or any of them
  may be bound, or to which any of the property or assets of the Company or any
  subsidiary is subject (except for such conflicts, breaches or defaults or
  liens, charges or encumbrances that would not have a Material Adverse Effect),
  nor will such action result in any violation of the provisions of the charter
  or by-laws of the Company or any subsidiary, or any applicable law, statute,
  rule, regulation, judgment, order, writ or decree, known to us, of any
  government, government instrumentality or court, domestic or foreign, having

       We have participated in conferences with officers and representatives of
  the Company and IMC, representatives of the independent accountants of the
  Company and IMC, and the Underwriter at which the contents of the ML&Co.
  Registration Statement and Prospectus, the contents of the IMC Registration
  Statement and Prospectus and related matters were discussed and, although we
  are not passing upon or assuming responsibility for the accuracy, completeness
  or fairness of the statements contained or incorporated by reference in said
  Registration Statements and Prospectuses and have made no independent check or
  verification thereof, on the basis of the foregoing, nothing has come to our
  attention that would lead us to believe (i) that the ML&Co. Registration
  Statement or any amendment thereto, including the Rule 430A Information and
  Rule 434 Information (if applicable), (except for financial statements and
  schedules and other financial data included or incorporated by reference
  therein or omitted therefrom and the Form T-1, as to which we make no
  statement), at the time such ML&Co. Registration Statement or any such
  amendment became effective or at the date of the Underwriting Agreement,
  contained an untrue statement of a material fact or omitted to state a
  material fact required to be stated therein or necessary to make the
  statements therein not misleading or that the ML&Co. Prospectus or any
  amendment or supplement thereto (except for financial statements and schedules
  and other financial data included or incorporated by reference therein or
  omitted therefrom, as to which we make no statement), at the  time the ML&Co.
  Prospectus was issued, at the time any such amended or supplemented prospectus
  was issued or at the Closing Time, included or includes an untrue statement of
  a material fact or omitted or omits to state a material fact necessary in
  order to make the statements therein, in the light of the circumstances under
  which they were made, not misleading, or (ii) that the IMC Registration
  Statement or any amendment thereto, (except for financial statements and
  schedules and other financial data included or incorporated by reference
  therein or omitted therefrom, as to which we make no statement), at the time
  such IMC Registration Statement or any such amendment became effective,
  contained an untrue statement of a material fact or omitted to state a
  material fact required to be stated therein or necessary to make the
  statements therein not misleading or that the IMC Prospectus or any amendment
  or supplement thereto (except for financial statements and schedules and other
  financial data included or incorporated by reference therein or omitted
  therefrom, as to which we make no statement), at the time the IMC Prospectus
  was issued, at the time any such amended or supplemented prospectus was issued
  or at the Closing Time, included or includes an untrue statement of a material
  fact or omitted or omits to state a material

                                      A-4

  fact necessary in order to make the statements therein, in the light of the
  circumstances under which they were made, not misleading.

  In rendering such opinion, such counsel may rely as to matters of fact (but
not as to legal conclusions), to the extent they deem proper, on certificates of
responsible officers of the Company and public officials.

  capital stock of any Subsidiary was issued in violation of the preemptive or

       (v) The IMC Registration Statement, including any IMC Rule 462(b)

  effectiveness of the IMC Registration Statement or any IMC Rule 462(b)
  Registration Statement has been issued under the 1933 Act and no proceedings
  for that purpose have been instituted or are pending or threatened by the
  Commission.

       (vi) The IMC Registration Statement, including any IMC Rule 462(b)
  Registration Statement, the IMC Prospectus, excluding the documents
  incorporated by reference therein, and each amendment or supplement to the IMC
  Registration Statement and IMC Prospectus, excluding the documents
  incorporated by reference therein, as of their respective effective or issue
  dates (other than the financial statements and supporting schedules included
  therein or omitted therefrom, as to which we express no opinion) complied as
  to form in all material respects with the requirements of the 1933 Act and the
  1933 Act Regulations.

       (vii)  The documents incorporated by reference in the IMC Prospectus
  (other than the financial statements and supporting schedules included therein
  or omitted therefrom, as to which we express no opinion), when they were filed
  with the Commission, complied as to form in all material respects with the

  action, suit, proceeding, inquiry or investigation, to which IMC or any
  subsidiary is a party, or to which the property of IMC or any subsidiary is
  subject, before or brought by any court or governmental agency or body,
  domestic or foreign, which might reasonably be expected to result in a
  Material Adverse Effect, or which might reasonably be expected to materially
  and adversely affect the properties or assets thereof or the consummation of
  the transactions contemplated in the Registration Agreement or the performance
  by IMC of its obligations thereunder.

       (x) The information in the Prospectus under
  "___________________________," "_________________________" and "Description of

  reviewed by us and is correct in all material respects.

       (xi) To the best of our knowledge, there are no statutes or regulations,
  and no legal or governmental proceedings pending or threatened to which IMC or

  under the securities or blue sky laws of the various states, as to which we
  express no opinion) is necessary or required in connection with the due
  authorization, execution, and delivery by IMC of the Registration Agreement or
  the performance by IMC of its obligations thereunder.

       (xiv) The execution, delivery and performance of the Registration
  Agreement and the consummation of the transactions contemplated in the
  Registration Agreement and in the IMC Registration Statement and compliance by
  IMC with its obligations under the Registration Agreement do not and will not,
  whether with or without the giving of notice or lapse of time or both,
  conflict with or constitute a breach of, or default or Repayment Event (as
  defined in Section 1(a)(xi) of the Registration Agreement) under or result in
  the creation or imposition of any lien, charge or encumbrance upon any
  property or assets of IMC or any subsidiary pursuant to, any contract,
  indenture, mortgage, deed of trust, loan or credit agreement, note, lease or
  any other agreement or instrument, known to us, to which IMC or any subsidiary
  is a party or by which it or any of them may be bound, or to which any of the
  property or assets of IMC or any subsidiary is subject (except for such
  conflicts, breaches or defaults or liens, charges or encumbrances that would
  not have a Material Adverse Effect), nor will such action result in any
  violation of the provisions of the charter or by-laws of IMC or any
  subsidiary, or any applicable law, statute, rule, regulation, judgment, order,
  writ or decree, known to us, of any government, government instrumentality or
  court, domestic or foreign, having jurisdiction over IMC or any subsidiary or
  any of their respective properties, assets or operations.

       [(xv)  IMC is not an "investment company" or an entity "controlled" by an
  "investment company," as such terms are defined in the 1940 Act.]

       We have participated in conferences with officers and representatives of
  IMC, representatives of the independent accountants of IMC, and the
  Underwriter at which the contents of the IMC Registration Statement and the
  IMC Prospectus and related matters were discussed and, although we are not
  passing upon or assuming responsibility for the accuracy, completeness or
  fairness of the statements contained or incorporated by reference in the IMC
  Registration Statement and the IMC Prospectus and have made no independent
  check or verification thereof except as described in paragraph (x) above, on
  the basis of the foregoing, nothing has come to our attention that would lead
  us to believe that the IMC Registration Statement or any amendment thereto
  (except for financial statements and schedules and other financial data
  included or incorporated by reference therein or omitted therefrom, as to
  which we make no statement), at the time such IMC Registration Statement or
  any such amendment became effective, contained an untrue statement of a
  material fact or omitted to state a material fact required to be stated
  therein or necessary to make the statements therein not misleading or that the
  IMC Prospectus or any amendment or supplement thereto (except for financial
  statements and schedules and other financial data included or incorporated by
  reference therein or omitted therefrom, as to which

                                      B-3
<PAGE>
 
  we need make no statement), at the time the IMC Prospectus was issued, at the
  time any such amended or supplemented prospectus was issued or at the Closing
  Time, included or includes an untrue statement of a material fact or omitted
  or omits to state a material fact necessary in order to make the statements
  therein, in the light of the circumstances under which they were made, not
  misleading.

       [In rendering such opinion, such counsel may rely (A) as to matters
  involving the application of laws other than the laws of the State of New
  York, the corporate laws of the State of Delaware or the federal laws of the
  United States of America, to the extent such counsel deems proper and
  specified in such opinion, upon the opinion of other counsel whom such counsel
  believes to be reliable, provided that such counsel furnishes copies thereof
  to the Underwriter and states that such opinion of such local counsel is
  satisfactory in form and substance and the Underwriter and counsel for the
  Underwriter are entitled to rely thereon, and (B) as to matters of fact (but
  not as to legal conclusions), to the extent they deem proper, on certificates
  of responsible officers of IMC and public officials.  As used in this Exhibit
  B, the terms "Material Adverse Effect," "Subsidiary" and "Subsidiaries" shall
  have the meanings ascribed to them in the Registration Agreement.]

                        FORM OF OPINION OF GVI'S COUNSEL
                          TO BE DELIVERED PURSUANT TO
                                SECTION 5(a)(5)



       (i) GVI has been duly incorporated and is validly existing as a

  agreement]).

       (iii)  The Underwriting Agreement has been duly authorized, executed and
  delivered by GVI.

       (iv) The Purchase Agreement has been duly authorized, executed and
  delivered by GVI and (assuming the due authorization, execution and delivery
  thereof by the Company) constitutes a valid and binding agreement of GVI,
  enforceable against GVI in accordance with its terms, except as the
  enforcement thereof may be limited by bankruptcy, insolvency (including,
  without limitation, all laws relating to fraudulent transfers),
  reorganization, moratorium or similar laws affecting enforcement of creditors'
  rights generally and except as enforcement thereof is subject to general
  principles of equity (regardless of whether enforcement is considered in a
  proceeding in equity or at law).

       (v) The execution, delivery and performance by GVI of the Underwriting
  Agreement and the Purchase Agreement and the consummation by GVI of the
  transactions contemplated therein and compliance by GVI with its obligations
  thereunder have been duly authorized by all necessary corporate action and do

  Repayment Event under or result in the creation or imposition of any lien,
  charge or encumbrance upon any property or assets of GVI or any of its
  subsidiaries pursuant to, any contract, indenture, mortgage, deed of trust,
  loan or credit agreement, note, lease or any other agreement or instrument,
  known to us, to which GVI or any of its subsidiaries is a party or by which it
  or any of them may be bound, or to which any of the property or assets of GVI
  or any of its subsidiaries is subject (except for such conflicts, breaches or
  defaults or liens, charges or encumbrances that would not, singly or in the

<PAGE>
 
  ability of GVI to perform its obligations under the Underwriting Agreement or
  the Purchase Agreement), nor will such action result in any violation of the
  provisions of the charter or by-laws of GVI or any of its subsidiaries, or any
  applicable law, statute, rule, regulation, judgment, order, writ or decree,
  known to us, of any government, government instrumentality or court, domestic
  or foreign, having jurisdiction over GVI or any of its subsidiaries or any of
  their respective assets, properties or operations (except for such violations

  the ability of GVI to perform its obligations under the Underwriting Agreement
  or the Purchase Agreement).

       (vi) To the best of our knowledge, no filing with, or authorization,
  approval, consent, license, order, registration, qualification or decree of,

  under the securities or blue sky laws of the various states, as to which we
  need express no opinion) is necessary or required in connection with the due
  authorization, execution and delivery by GVI of the Underwriting Agreement or
  the Purchase Agreement or the performance by GVI of its obligations
  thereunder.

       We have participated in conferences with officers and representatives of
  GVI, IMC and the Underwriter at which the contents of the IMC Registration
  Statement and the IMC Prospectus relating to GVI were discussed and, although
  we are not passing upon or assuming responsibility for the accuracy,
  completeness or fairness of the statements contained in the IMC Registration
  Statement and the IMC Prospectus relating to GVI and have made no independent
  check or verification thereof, on the basis of the foregoing, nothing has come
  to our attention that would lead us to believe that the IMC Registration
  Statement or any amendment thereto (only with respect to the information
  included therein or omitted therefrom relating to GVI), at the time such IMC
  Registration Statement or any such amendment became effective, contained an
  untrue statement of a material fact or omitted to state a material fact
  required to be stated therein or necessary to make the statements therein not
  misleading or that the IMC Prospectus or any amendment or supplement thereto
  (only with respect to the information included therein or omitted therefrom
  relating to GVI), at the time the IMC Prospectus was issued, at the time any
  such amended or supplemented prospectus was issued or at the Closing Time,
  included or includes an untrue statement of a material fact or omitted or
  omits to state a material fact necessary in order to make the statements
  therein, in the light of the circumstances under which they were made, not
  misleading.


       [In rendering such opinion, such counsel may rely (A) as to matters
  involving the application of laws other than [the laws of the State of New
  York,] the laws of the State of Illinois, the corporate laws of the State of
  Delaware or the federal laws of the United States of America, to the extent
  such counsel deems proper and specified in such opinion, upon the opinion of
  other counsel whom such counsel believes to be reliable, provided that such
  counsel furnishes copies thereof to the Underwriter and states that such
  opinion of such local counsel is satisfactory in form and substance and the
  Underwriter and counsel for the Underwriter are entitled to rely thereon, and
  (B) as to matters of fact (but not as to legal conclusions), to the extent
  they deem proper, on certificates of responsible officers of GVI and public
  officials.]

Ladies and Gentlemen:

     IMC Global Inc., a Delaware corporation (the "Company"), confirms its
agreement with Merrill Lynch & Co., Inc., a Delaware corporation ("ML&Co."), and
Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated (the
"Underwriter"), in connection with the proposed issue and sale by ML&Co. to the
Underwriter, pursuant to an underwriting agreement, dated the date hereof (the
"Underwriting Agreement"), among ML&Co., GVI Holdings, Inc.,  a Delaware
corporation ("GVI"), and the Underwriter, of an aggregate of 5,661,119 of
ML&Co.'s Structured Yield Product Exchangeable for Stock/SM/, ___% STRYPES/SM/
Due ________, 2001 (each, a "STRYPES"), payable at maturity by delivery of
shares of common stock, par value $1.00 per share (the "IMC Common Stock"), of
the Company, and, at the option of the Underwriter, all or any part of 849,167
additional STRYPES to cover over-allotments, if any.

_______________

/SM/ Service mark of Merrill Lynch & Co., Inc.

                                       1
<PAGE>
 
The aforesaid 5,661,119 STRYPES (the "Initial Securities") to be purchased by
the Underwriter and all or any part of the 849,167 STRYPES subject to the option
described in Section 2(b) of the Underwriting Agreement (the "Option
Securities") are hereinafter called, collectively, the "Securities."
Capitalized terms used herein and not otherwise defined shall have the meanings
ascribed to them in the Underwriting Agreement.

     The Company understands that the Underwriter proposes to make a public
offering of the Securities as soon as the Underwriter deems advisable after this
Agreement and the Underwriting Agreement have been executed and delivered.  The
Company acknowledges that the execution and delivery of this Agreement is a
condition to the execution and delivery of the Underwriting Agreement by the
Underwriter and ML&Co. and that, in consideration of the execution and delivery
of the Underwriting Agreement by the Underwriter and ML&Co., the Company is
willing to make the representations, warranties and covenants herein contained.

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-      ) covering the
registration under the Securities Act of 1933, as amended (the "1933 Act"), of
the shares of IMC Common Stock deliverable upon payment and discharge of the
Securities, including the related preliminary prospectus or prospectuses.  Each
prospectus used before such registration statement became effective is herein
called an "IMC preliminary prospectus."  Such registration statement, including
the exhibits thereto, the schedules thereto, if any, and the documents
incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933
Act, at the time it became effective, is herein called the "IMC Registration
Statement."  Any registration statement filed pursuant to Rule 462(b) of the
rules and regulations of the Commission under the 1933 Act (the "1933 Act
Regulations") is herein referred to as the "IMC Rule 462(b) Registration
Statement," and after such filing the term "IMC Registration Statement" shall
include the IMC Rule 462(b) Registration Statement.  The final prospectus,
including the documents incorporated by reference therein pursuant to Item 12 of
Form S-3 under the 1933 Act, in the form first furnished to the Underwriter for
use in connection with the offering of the Securities is herein called the "IMC
Prospectus."  For purposes of this Agreement, all references to the IMC
Registration Statement, any IMC preliminary prospectus, the IMC Prospectus or
any amendment or supplement to any of the foregoing shall be deemed to include
the copy filed with the Commission pursuant to its Electronic Data Gathering,
Analysis and Retrieval system ("EDGAR").

     All references in this Agreement to financial statements and schedules and
other information which are "contained," "included" or "stated" in the IMC
Registration Statement, any IMC preliminary prospectus or the IMC Prospectus (or
other references of like import) shall be deemed to mean and include all such
financial statements and schedules and other information which are incorporated
by reference in the IMC Registration Statement, any IMC preliminary prospectus
or the IMC Prospectus, as the case may be; and all references in this Agreement
to amendments or supplements to the IMC Registration Statement, any IMC
preliminary prospectus or the IMC Prospectus shall be deemed to mean and include
the filing of any document under the Securities Exchange Act of 1934, as amended
(the "1934 Act"), which is incorporated by reference in the IMC Registration
Statement, such IMC preliminary prospectus or the IMC Prospectus, as the case
may be.

     Prior to the closing under the Underwriting Agreement, ML&Co., Merrill
Lynch Mortgage Capital Inc., a wholly-owned subsidiary of ML&Co., and GVI will
enter into a contract, pursuant to which GVI will agree to sell and ML&Co. will
agree to purchase, immediately prior to the maturity date of the Securities, the
Maturity Consideration (as defined in the Supplemental Indenture) required by
ML&Co. to pay and discharge all of the Securities at maturity as described in
the ML&Co. Prospectus, subject to GVI's right to require that the obligations
thereunder be satisfied by a cash payment based on the value of such Maturity
Consideration.


     SECTION 1.  Representations and Warranties.
                 ------------------------------ 

     (a) Representations and Warranties by the Company.  The Company represents
and warrants to each of the Underwriter and to ML&Co. as of the date hereof, as
of the Closing Time referred to in Section 2(c) of the Underwriting Agreement,
and as of each Date of Delivery (if any) referred to in Section 2(b) of the
Underwriting Agreement, and agrees with each of the Underwriter and ML&Co. as
follows:

          (i)  Compliance with Registration Requirements.  The Company meets the
               -----------------------------------------                        
     requirements for the use of Form S-3 under the 1933 Act.  Each of the IMC
     Registration Statement and any IMC Rule 462(b) Registration Statement has
     become effective under the 1933 Act and no stop order suspending the
     effectiveness of the IMC Registration Statement or any IMC Rule 462(b)
     Registration Statement has been issued under the 1933 Act and no
     proceedings for that purpose have been instituted or are pending or, to the
     knowledge of the Company, are contemplated by the Commission, and any
     request on the part of the Commission for additional information has been
     complied with.

          At the respective times the IMC Registration Statement, any IMC Rule
     462(b) Registration Statement and any post-effective amendments thereto
     became effective and at the Closing Time (and, if any Option Securities are
     purchased, at the Date of Delivery), the IMC Registration Statement, the
     IMC Rule 462(b) Registration Statement and any amendments and supplements
     thereto complied and will comply in all material respects with the
     requirements of the 1933 Act and the 1933 Act Regulations and did not and
     will not contain an untrue statement of a material fact or omit to state a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading.  Neither the IMC Prospectus nor any
     amendments or supplements thereto, at the time the IMC Prospectus or any
     such amendment or supplement was issued and at the Closing Time (and, if
     any Option Securities are purchased, at the Date of Delivery), included or
     will include an untrue statement of a material fact or omitted or will omit
     to state a material fact necessary in order to make the statements therein,
     in the light of the circumstances under which they were made, not
     misleading.  The representations and warranties in this subsection shall
     not apply to statements in or omissions from the IMC Registration Statement
     or IMC Prospectus made in reliance upon and in conformity with information
     furnished to the Company in writing by the Underwriter, ML&Co. or GVI
     expressly for use in the IMC Registration Statement or IMC Prospectus.

          Each IMC preliminary prospectus and the IMC Prospectus filed as part
     of the IMC Registration Statement as originally filed or as part of any
     amendment thereto, or filed 

                                       3
<PAGE>
 
     pursuant to Rule 424 under the 1933 Act, complied when so filed in all
     material respects with the 1933 Act Regulations and, if applicable, each
     IMC preliminary prospectus and the IMC Prospectus delivered to the
     Underwriter for use in connection with the offering of the Securities was
     identical to the electronically transmitted copies thereof filed with the
     Commission pursuant to EDGAR, except to the extent permitted by Regulation
     S-T.

          (ii)  Incorporated Documents.  The documents incorporated or deemed to
                ----------------------                                          
     be incorporated by reference in the IMC Registration Statement and the IMC
     Prospectus, when they became effective or at the time they were or
     hereafter are filed with the Commission, complied and will comply in all
     material respects with the requirements of the 1934 Act and the rules and
     regulations of the Commission thereunder (the "1934 Act Regulations"), and,
     when read together with the other information in the IMC Prospectus, at the
     time the IMC Registration Statement and any post-effective amendments
     thereto became effective, at the time the IMC Prospectus was issued and at
     the Closing Time (and if any Option Securities are purchased, at the Date
     of Delivery), did not and will not contain an untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading.

          (iii)  Independent Accountants.  The accountants who certified the
                 -----------------------                                    
     financial statements and supporting schedules of the Company and its
     subsidiaries, and of The Vigoro Corporation and its subsidiaries
     ("Vigoro"), included in the IMC Registration Statement are independent
     public accountants as required by the 1933 Act and the 1933 Act
     Regulations.

          (iv)  Financial Statements.  The financial statements of the Company
                --------------------                                          
     (including the financial statements giving retroactive effect to the merger
     of the Company and Vigoro) included in the IMC Registration Statement and
     the IMC Prospectus, together with the related schedules and notes, present
     fairly the financial position of the Company and its consolidated
     subsidiaries at the dates indicated and the statement of operations,
     stockholders' equity and cash flows of the Company and its consolidated
     subsidiaries for the periods specified; said financial statements have been
     prepared in conformity with generally accepted accounting principles
     ("GAAP") applied on a consistent basis throughout the periods involved.
     The financial statements of Vigoro included in the IMC Registration
     Statement and the IMC Prospectus, together with the related notes, present
     fairly the financial position of Vigoro and its consolidated subsidiaries
     at the dates indicated and the statement of operations, stockholders'
     equity and cash flows of Vigoro and its consolidated subsidiaries for the
     periods specified; said financial statements have been prepared in
     conformity with GAAP applied on a consistent basis throughout the periods
     involved.  The supporting schedules, if any, included in the IMC
     Registration Statement present fairly in accordance with GAAP the
     information required to be stated therein.  The selected consolidated
     financial information and the summary selected consolidated financial
     information included in the IMC Prospectus present fairly the
     information shown therein and have been compiled on a basis consistent with
     that of the audited financial statements included in the IMC Registration
     Statement.  The pro forma financial statements and the other pro forma
     financial information of the Company and its subsidiaries and the related
     notes thereto included in the IMC Registration Statement

     information shown therein, have been prepared in accordance with the
     Commission's rules and guidelines with respect to pro forma financial
     statements and have been properly compiled on the bases described therein,
     and the assumptions used in the preparation thereof are reasonable and the
     adjustments used therein are appropriate to give effect to the transactions
     and circumstances referred to therein.

          (v)  No Material Adverse Change in Business.  Since the respective
               --------------------------------------                       
     dates as of which information is given in the IMC Registration Statement
     and the IMC Prospectus, except as otherwise stated therein or contemplated
     thereby, (A) there has been no material adverse change in the condition,

in order that the IMC Prospectus will not include any untrue statements of a
material fact or omit to state a material fact necessary in order to make the

ML&Co. within the meaning of Section 15 of the 1933 Act or Section 20 of the
1934 Act, as follows:

          (i) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in the IMC Registration
     Statement (or any amendment thereto) or the omission or alleged omission
     therefrom of a material fact required to be stated therein or necessary to
     make the statements therein not misleading or arising out of any untrue
     statement or alleged untrue statement of a material fact contained in any
     IMC preliminary prospectus or the IMC Prospectus (or any amendment or
     supplement thereto), or the omission or alleged omission therefrom of a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

          (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, referred to under (i) above; provided
     that (subject to Section 4(d) below) any such settlement is effected with
     the written consent of the Company; and

          (iii)  against any and all expense whatsoever, as incurred (including
     the fees and disbursements of counsel chosen by the Underwriter or ML&Co.,
     as the case may be), reasonably incurred in investigating, preparing or
     defending against any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or any claim
     whatsoever based upon any such untrue statement or omission,

                                       12
<PAGE>
 
     or any such alleged untrue statement or omission, referred to under (i)
     above, to the extent that any such expense is not paid under (i) or (ii)
     above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by the
Underwriter, ML&Co. or GVI expressly for use in the IMC Registration Statement
(or any amendment thereto), or any IMC preliminary prospectus or the IMC
Prospectus (or any amendment or supplement thereto).

     (b) Indemnification of Company, Directors, Officers.  The Underwriter
agrees to indemnify and hold harmless the Company, its directors, each of its
officers who signed the IMC Registration Statement, and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act against any and all loss, liability, claim, damage and
expense described in the indemnity contained in subsection (a) of this Section,
as incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the IMC Registration Statement (or any
amendment thereto),  or any IMC preliminary prospectus or the IMC Prospectus (or
any amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Company by the Underwriter expressly for
use in the IMC Registration Statement (or any amendment thereto) or such IMC
preliminary prospectus or the IMC Prospectus (or any amendment or supplement
thereto).

     (c) Actions against Parties; Notification.  Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement.  In the case of parties indemnified pursuant to clause (1) of Section
4(a) above, counsel to the indemnified parties shall be selected by the
Underwriter; in the case of parties indemnified pursuant to clause (2) of
Section 4(a), counsel to the indemnified parties shall be selected by ML&Co.;
and, in the case of parties indemnified pursuant to Section 4(b) above, counsel
to the indemnified parties shall be selected by the Company.  An indemnifying
party may participate at its own expense in the defense of any such action;
provided, however, that counsel to the indemnifying party shall not (except with
the consent of the indemnified party) also be counsel to the indemnified party.
In no event shall the indemnifying parties be liable for fees and expenses of
more than one counsel (in addition to any local counsel) separate from their own
counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances.  No indemnifying party shall,
without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought under this Section 4 or Section
5 hereof (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an

                                       13
<PAGE>
 
unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as to or an admission of fault, culpability or a failure to act by
or on behalf of any indemnified party.

     (d) Settlement without Consent if Failure to Reimburse.  If at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 4(a)(ii) effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.

     SECTION 5.  Contribution.  If the indemnification provided for in Section 4
                 ------------                                                   
hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then the Company on the one hand and the
Underwriter and ML&Co. on the other hand shall contribute to the aggregate
amount of such losses, liabilities, claims, damages and expenses incurred by
such indemnified party, as incurred, (i) in such proportion as is appropriate to
reflect the relative benefits received by the Company on the one hand and the
Underwriter and ML&Co. on the other hand from the offering of the Securities or
(ii) if the allocation provided by clause (i) is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of the
Company on the one hand and of the Underwriter and ML&Co. on the other hand in
connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.

     The relative benefits received from the offering of the Securities shall be
deemed to be such that the Underwriter and ML&Co. shall be responsible for that
portion of the aggregate amount of such losses, liabilities, claims, damages and
expenses represented by the percentage that the total underwriting discount
received by the Underwriter, as set forth on the cover of the ML&Co. Prospectus,
or, if Rule 434 is used, the corresponding location on the ML&Co. Term Sheet,
bears to the aggregate initial public offering price of the Securities as set
forth on such cover and the Company shall be responsible for the balance.

     The relative fault of the Company on the one hand and the Underwriter and
ML&Co. on the other hand shall be determined by reference to, among other
things, whether any such untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by the Company or GVI on the one hand or by the Underwriter or ML&Co.
on the other hand and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

     Notwithstanding the provisions of this Section 5, the Underwriter and
ML&Co. shall not be required to contribute any amount in excess of the amount by
which the total price at which the Securities underwritten by the Underwriter
and distributed to the public were offered to the 

                                       14
<PAGE>
 
public exceeds the amount of any damages which the Underwriter and ML&Co. have
otherwise been required to pay by reason of any such untrue or alleged untrue
statement or omission or alleged omission.

     The Company, the Underwriter and ML&Co. agree that it would not be just and
equitable if contribution pursuant to this Section 5 were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this Section 5.  The aggregate
amount of losses, liabilities, claims, damages and expenses incurred by an
indemnified party and referred to above in this Section 5 shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 5, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as the Underwriter; each
person, if any, who controls ML&Co. within the meaning of Section 15 of the 1933
Act shall have the same rights to contribution as ML&Co.; and each director of
the Company, each officer of the Company who signed the IMC Registration
Statement, and each person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same
rights to contribution as the Company.

     SECTION 6.  Representations, Warranties and Agreements to Survive Delivery.
                 -------------------------------------------------------------- 
All representations, warranties and agreements contained in this Agreement or in
certificates of officers of the Company submitted pursuant to the Underwriting
Agreement, shall remain operative and in full force and effect, regardless of
any investigation made by or on behalf of the Underwriter or controlling person
thereof, or by or on behalf of ML&Co. or controlling person thereof or by or on
behalf of the Company, and shall survive delivery of the Securities to the
Underwriter pursuant to the Underwriting Agreement.

     SECTION 7.  Termination.  In the event that the Underwriter terminates the
                 -----------                                                   
Underwriting Agreement as provided in Section 9 thereof, this Agreement shall
simultaneously terminate, except that the provisions of Section 3, the indemnity
agreements set forth in Section 4, the contribution provisions set forth in
Section 5, and the provisions of Section 6 shall remain in effect.

     SECTION 8.  Notices.  All notices and other communications hereunder shall
                 -------

Corporate Secretary.

     SECTION 9.  Parties.  This Agreement shall inure to the benefit of and be
                 -------                                                      
binding upon each of the Underwriter, ML&Co. and the Company and their
respective successors.  Nothing expressed or mentioned in this Agreement is
intended or shall be construed to give any person, firm or corporation, other
than the Underwriter, ML&Co. and the Company and their respective successors and
the controlling persons and officers and directors referred to in Sections 4 and
5 and their heirs and legal representatives, any legal or equitable right,
remedy or claim under or in respect of this Agreement or any provision herein
contained.  This Agreement and all conditions and provisions hereof are intended
to be for the sole and exclusive benefit of the Underwriter, ML&Co. and the
Company and their respective successors, and said controlling persons and
officers and directors and their heirs and legal representatives, and for the
benefit of no other person, firm or corporation.  No purchaser of Securities
from the Underwriter shall be deemed to be a successor by reason merely of such
purchase.

     SECTION 10. GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND
                 -------------                                          
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     SECTION 11. Effect of Headings.  The Article and Section headings herein

                                  THE STRYPES

     SECTION 201.   Description of the STRYPES.  The Securities shall be known
                    --------------------------                                
and designated as the "Structured Yield Product Exchangeable for Stock, __%
STRYPES Due _________, 2001" of the Company.  The aggregate number of STRYPES
which may be authenticated and delivered under this Supplemental Indenture is
limited to 6,510,286 with an issue price of $_____ per STRYPES, or $___________

<PAGE>
 
registration of transfer of, or in exchange for, or in lieu of, other STRYPES
Certificates evidencing such STRYPES pursuant to Section 304, 305, 306 or 906 of
the Principal Indenture.

     The STRYPES shall mature on _________, 2001 (the "Maturity Date").  On the
Maturity Date, the STRYPES shall be paid and discharged as provided in Article
Three of this Supplemental Indenture.

     The STRYPES shall bear interest at the rate of __% of the issue price per
annum (or $ ____ per annum), from _______, 1996, or from the most recent
Interest Payment Date to which interest has been paid or duly provided for, as
the case may be, until the Maturity Date or such earlier date on which the issue
price of all STRYPES is repaid in accordance with the provisions of the
Indenture.  Interest shall be payable in cash quarterly in arrears on
___________, ___________, ___________ and ___________, beginning ___________,
1996, and on the Maturity Date (each, an "Interest Payment Date"), to the
Persons in whose names the STRYPES are registered at the close of business on
the fifteenth calendar day (whether or not a Business Day) immediately preceding
such Interest Payment Date (each, a "Regular Record Date").  Interest on the
STRYPES shall be computed on the basis of a 360-day year of twelve 30-day
months.

     The interest on the STRYPES shall be payable and the Maturity Consideration
shall be deliverable or payable at the office or agency of the Company in the
Borough of Manhattan, The City of New York maintained for such purpose and at
any other office or agency maintained by the Company for such purpose; provided,
however, that at the option of the Company payment of interest may be made by
check mailed to the address of the Person entitled thereto as such address shall

     The STRYPES shall not be redeemable at the option of the Company, or

                                 ARTICLE THREE

                        PAYMENT AND DISCHARGE OF STRYPES

     SECTION 301.  Payment and Discharge on the Maturity Date.   On the Maturity
                   ------------------------------------------                   
Date, the Company shall pay and discharge each STRYPES by delivering to the
Holder thereof:  (a) if the Reference Property Value is greater than or equal to
$_____ (the "Threshold Appreciation Price"), ____% of the amount or number of
each type of Reference Security and other property constituting part of the
Reference Property, (b) if the Reference Property Value is less than the
Threshold Appreciation Price but is greater than $_____ (the "Initial Price"), a
percentage of the amount or number of each type of Reference Security and other
property constituting part of the Reference Property, allocated as
proportionately as practicable, so that the aggregate value thereof is equal to
the Initial Price and (c) if the Reference Property Value is less than or equal
to the Initial Price, 100% of the amount or number of each type of Reference
Security and other property constituting part of the Reference Property.

     The term "Reference Property" shall initially mean one share of IMC Common
Stock and shall be subject to adjustment from time to time prior to the Maturity
Date to reflect the addition or substitution of any cash, securities and/or
other property resulting from the application of the provisions of Section 303
of this Article Three.

     Holders of the STRYPES will be responsible for the payment of any and all
brokerage and transaction costs upon any subsequent sale of any Reference
Security or other property constituting part of the Reference Property received
on the Maturity Date as described above.

     SECTION 302.  No Fractional Units.  No fractional units or scrip
                   -------------------                               
representing fractional units of any Reference Security shall be delivered on
the Maturity Date.  If more than one STRYPES shall be held at one time by the
same Holder, the number of full units of any Reference Security which shall be
delivered upon payment and discharge of such Holder's STRYPES shall be computed
on the basis of the aggregate number of STRYPES so held on the Maturity Date.
In lieu of any fractional unit of any Reference Security which would otherwise
be deliverable upon payment and discharge of any STRYPES on the Maturity Date,
the Company, through any applicable Paying Agent, shall make a cash payment in
respect of such fractional unit in an amount equal to the value of such
fractional unit based on the average Closing Price per unit of such Reference
Security on the 20 Trading Days immediately prior to, but not including, the
second Trading Day preceding the Maturity Date.

     To the extent practicable, the Company will deliver fractional interests of
any Reference Property other than cash or

                                       7
<PAGE>
 
a Reference Security upon payment and discharge of any STRYPES on the Maturity
Date.  If such delivery is not practicable, in lieu of any fractional interest
of any Reference Property other than cash or a Reference Security which would
otherwise be deliverable on the Maturity Date, the Company, through any Paying
Agent, shall make a cash payment in respect of such fractional interest in an
amount equal to the value of such fractional interest based on the fair market
value (as determined by a nationally recognized independent investment banking
firm retained for this purpose by the Company) as of the third Trading Day
preceding the Maturity Date of such Reference Property other than cash or a
Reference Security.

     SECTION 303.  Adjustment of Reference Property.
                   -------------------------------- 

     (a)  Adjustment for Subdivisions, Splits, Combinations or
          ----------------------------------------------------
Reclassifications.  If an issuer of a Reference Security shall:
- ------------------                                             

               (A)  subdivide or split the outstanding units of such Reference
     Security into a greater number of units;

               (B)  combine the outstanding units of such Reference Security
     into a smaller number of units; or

               (C)  issue by reclassification of units of such Reference
     Security any units of another security of such issuer;

then, in any such event, the Reference Property shall be adjusted to include the
number of units of such Reference Security and/or other security of such issuer
which a holder of units of such Reference Security would have owned or been
entitled to receive immediately following any event described above had such
holder held, immediately prior to such event, the number of units of such
Reference Security constituting part of the Reference Property immediately prior
to such event.  Each such adjustment shall become effective immediately after
the effective date for such subdivision, split, combination or reclassification,
as the case may be.  Each such adjustment shall be made successively.

     (b)  Adjustment for Issuance of Certain Rights or Warrants.  If an issuer
          ------------------------------------------------------              
of a Reference Security shall issue rights or warrants to all holders of such
Reference Security entitling them, for a period expiring prior to the fifteenth
calendar day following the Maturity Date, to subscribe for or purchase any of
its securities or other property (other than rights to purchase units of such
Reference Security pursuant to a plan for the reinvestment of dividends or
interest), then in each such case, the Reference Property shall be adjusted to
include an amount in cash equal to the fair market value (determined as
described below), as of the fifth Business Day following the date on which such
rights or warrants are received by securityholders entitled thereto (the
"Receipt Date"), of each such right or warrant

                                       8
<PAGE>
 
multiplied by the product of (A) the number of such rights or warrants issued
for each unit of such Reference Security and (B) the number of units of such
Reference Security constituting part of the Reference Property on the date of
issuance of such rights or warrants, immediately prior to such issuance, without
interest thereon.  For purposes of this subsection (b), the fair market value of
each such right or warrant shall be determined by the Company and shall be the
quotient of (x) the highest net bid, as of approximately 10:00 A.M., New York
City time, on the fifth Business Day following the Receipt Date for settlement
three Business Days later, by a recognized securities dealer in The City of New
York selected by or on behalf of the Company (from three (or such fewer number
of dealers as may be providing such bids) such recognized dealers selected by or
on behalf of the Company), for the purchase by such quoting dealer of the number
of rights or warrants (the "Aggregate Number") that a holder of such Reference
Security would receive if such holder held, as of the record date for
determination of stockholders entitled to receive such rights or warrants, a
number of units of such Reference Security equal to the product of (1) the
aggregate number of Outstanding STRYPES as of such record date and (2) the
number of units of such Reference Security constituting part of the Reference
Property, divided by (y) the Aggregate Number.  Each such adjustment shall
become effective on the fifth Business Day following the Receipt Date of such
rights or warrants.  If for any reason the Company is unable to obtain the
required bid on the fifth Business Day following the Receipt Date, it shall
attempt to obtain such bid at successive intervals of three months thereafter
and on the third Trading Day prior to the Maturity Date until it is able to
obtain the required bid.  From the date of issuance of such rights or warrants
until the required bid is obtained, the Reference Property shall include the
number of such rights or warrants issued for each unit of such Reference
Security multiplied by the number of units of such Reference Security
constituting part of the Reference Property on the date of issuance of such
rights or warrants, immediately prior to such issuance, and such rights or
warrants constituting part of the Reference Property shall be deemed for
purposes of the definition of Reference Property Value and Section 304 of this
Article Three to have a fair market value of zero.

     (c)  Adjustment for Distributions.   If an issuer of a Reference Security
          -----------------------------                                       
shall pay a dividend or make a distribution to all holders of such Reference
Security of cash, securities or other property (excluding any cash dividend on
any Reference Security consisting of capital stock that does not constitute an
Extraordinary Cash Dividend, excluding any payment of interest on any Reference
Security consisting of an evidence of indebtedness and excluding any dividend or
distribution described in subsection (a) or (b) above) or shall issue to all
holders of such Reference Security rights or warrants to subscribe for or
purchase any of its securities or other property (excluding any rights or
warrants referred to in subsection (b) above) (any of

                                       9
<PAGE>
 
the foregoing being referred to herein as "Distributed Assets"), then in each
such case, the Reference Property shall be adjusted to include, from and after
such dividend, distribution or issuance, (x) in respect of that portion, if any,
of the Distributed Assets consisting of cash, the amount of such Distributed
Assets consisting of cash received for each unit of such Reference Security
multiplied by the number of units of such Reference Security constituting part
of the Reference Property on the date of such dividend, distribution or
issuance, immediately prior to such dividend, distribution or issuance, without
interest thereon, plus (y) in respect of that portion, if any, of the
Distributed Assets which are other than cash, the number or amount of each type
of Distributed Assets other than cash received with respect to each unit of such
Reference Security multiplied by the number of units of such Reference Security
constituting part of the Reference Property on the date of such dividend,
distribution or issuance, immediately prior to such dividend, distribution or
issuance.

     (d)   Adjustment for Consolidation, Merger or Other Reorganization Event.
           ------------------------------------------------------------------  
In the event of (i) any consolidation or merger of an issuer of a Reference
Security with or into another entity (other than a merger or consolidation in
which such issuer is the continuing corporation and in which the Reference
Security outstanding immediately prior to the merger or consolidation is not
exchanged for cash, securities or other property of such issuer or another
entity), (ii) any statutory exchange of securities of an issuer of a Reference
Security with another entity (other than in connection with a merger or
acquisition) or (iii) any liquidation, dissolution, winding up or bankruptcy of
an issuer of a Reference Security (excluding any distribution in such event
referred to in subsection (c) above) (any such event described in clause (i),
(ii) or (iii), a "Reorganization Event"), the Reference Property shall be
adjusted to include, from and after the effective date for such Reorganization
Event, in lieu of the number of units of such Reference Security constituting
part of the Reference Property immediately prior to the effective date for such
Reorganization Event, the amount or number of any cash, securities and/or other
property owned or received in such Reorganization Event with respect to each
unit of such Reference Security multiplied by the number of units of such
Reference Security constituting part of the Reference Property immediately prior
to the effective date for such Reorganization Event.

     SECTION 304.  Payment and Discharge With Cash.   Notwithstanding the
                   -------------------------------                       
provisions of Sections 301, 302 and 303 of this Article Three, the Company may,
at its option, in lieu of delivering the applicable percentage of each type of
Reference Security and other property constituting part of the Reference
Property on the Maturity Date, deliver cash in an amount (calculated to the
nearest 1/100th of a dollar per STRYPES or, if there is not a nearest 1/100th of
a dollar, then to the next

                                       10
<PAGE>
 
higher 1/100th of a dollar) equal to the sum of (a) for any portion of the
Reference Property consisting of cash that is otherwise deliverable on the
Maturity Date, the amount of such cash, without interest thereon, (b) for any
portion of the Reference Property consisting of property other than cash or
Reference Securities that is otherwise deliverable on the Maturity Date, the
fair market value (as determined by a nationally recognized independent
investment banking firm retained for this purpose by the Company) as of the
third Trading Day preceding the Maturity Date of such property, and (c) for any
portion of the Reference Property consisting of a Reference Security (including
IMC Common Stock) that is otherwise deliverable on the Maturity Date (except as
provided in Section 303(b)), an amount equal to the average Closing Price per
unit of such Reference Security on the 20 Trading Days immediately prior to, but
not including, the second Trading Day preceding the Maturity Date multiplied by
the number of units of such Reference Security constituting part of the
Reference Property.  Such option, if exercised by the Company, must be exercised
with respect to all Reference Securities and other property otherwise
deliverable on the Maturity Date upon payment and discharge of all Outstanding
STRYPES.

     SECTION 305.  Notice of Adjustments and Certain Other Events.
                   ---------------------------------------------- 

     (a)  In case at any time while any of the STRYPES are outstanding the
Company receives notice that:

          (i)  an issuer of a Reference Security shall declare a dividend (or
any other distribution) on or in respect of such Reference Security to which
Section 303(c) shall apply (other than any cash dividends, if any, paid from
time to time by such issuer that do not constitute Extraordinary Cash
Dividends);

          (ii)  an issuer of a Reference Security shall authorize the issuance
to all holders of such Reference Security of rights or warrants to subscribe for
or purchase units of such Reference Security or of any other subscription rights
or warrants;

          (iii)  there shall occur any conversion or reclassification of any
Reference Security (other than a subdivision or combination of outstanding units
of such Reference Security) or any consolidation, merger or reorganization to
which an issuer of a Reference Security is a party and for which approval of any
unitholders of such issuer is required, or the sale or transfer of all or
substantially all of the assets of an issuer of a Reference Security; or

          (iv)  there shall occur the voluntary or involuntary dissolution,
liquidation, winding up or bankruptcy of an issuer of a Reference Security;

                                       11

                                     TAXES

     SECTION 401.   Documentary, Stamp, Transfer or Similar Taxes.  The Company
                    ---------------------------------------------              
will pay any and all documentary, stamp, transfer or similar taxes that may be
payable in respect of the transfer and delivery of the Maturity Consideration
pursuant to this Supplemental Indenture; provided, however, that the Company
shall not be required to pay any such tax which may be payable in respect of any
transfer involved in the delivery of Maturity Consideration in a name other than
that in which the STRYPES so paid and discharged were registered, and no such
transfer or delivery shall be made unless and until the Person requesting such
transfer has paid to the Company the amount of any such tax, or has established,
to the satisfaction of the Company, that such tax has been paid.

     SECTION 402.   Treatment of STRYPES.  The parties hereto hereby agree, and
                    --------------------                                       
each Holder of a STRYPES by its purchase of a STRYPES hereby agrees:

       (a) to treat, for all United States Federal, state and local tax
          purposes, each STRYPES as a unit (a "Unit") consisting of (A) a debt
          instrument (the "Debt Instrument") with a fixed principal amount
          unconditionally payable on the Maturity Date equal to the issue price
          of the STRYPES and bearing interest at the stated interest rate on the
          STRYPES and (B) a forward purchase contract (the "Forward Contract")
          pursuant to which the Holder is irrevocably committed to use the
          principal payment due on the Debt Instrument to purchase on the
          Maturity Date the Maturity Consideration which the Company is
          obligated to deliver at that time (subject to the Company's right to
          deliver cash with an equal value), which treatment will require, among
          other things, each Holder that is subject to United States Federal
          income tax in connection with its ownership of the STRYPES to include
          currently in income and ordinary interest payments denominated as
          interest that are made with respect to the STRYPES in accordance with
          such Holder's regular method of tax accounting;

                                       13
<PAGE>
 
       (b) in the case of purchases of STRYPES in connection with the original
issuance thereof, (A) to allocate $____________ of the entire initial purchase
price of a STRYPES (i.e., the issue price of a STRYPES) to the Debt Instrument
component and to allocate the remaining $___________ of the entire initial
purchase price of a STRYPES to the Forward Contract component and (B) to treat
such acquisition of the STRYPES by the Holder as a purchase of the Debt
Instrument by the Holder for $__________ and the making of an initial payment by
the Holder with respect to the Forward Contract of $__________;

       (c) in the case of purchases and sales of STRYPES subsequent to the
          original issuance thereof, the purchase price paid (or received) by a
          Holder will be allocated by the Holder between the Debt Instrument and
          the Forward Contract based upon their relative fair market values (as
          determined on the date of acquisition or disposition);

       (d) to file all United States Federal, state and local income, franchise
          and estate tax returns consistent with the treatment of each STRYPES
          as a Unit consisting of the Debt Instrument and the Forward Contract
          (in the absence of any change or clarification in applicable law, by
          regulation or otherwise, requiring a different characterization or
          treatment of the STRYPES).

     the reason for such Event of Default and whether it shall be voluntary or
     involuntary or be effected by operation of law pursuant to any judgment,
     decree or order of any court or any order, rule or regulation of any

     any corporate action in furtherance of any of the foregoing."

     (c)   By deleting Section 502 of the Principal Indenture in its entirety
and inserting in its stead the following:

     "SECTION 502.  Acceleration of Maturity; Rescission and Annulment.  If an
     Event of Default (other than an Event of Default specified in Section
     501(4) or 501(5)) occurs and is continuing, then and in every such case the
     Trustee or the Holders of not less than 25% of the aggregate issue price of
     the Outstanding STRYPES may declare an amount equal to the issue price of
     all the STRYPES to be due and payable immediately, by a notice in writing
     to the Company (and to the Trustee if given by the Holders), and upon any
     such declaration such amount shall become immediately due and payable in
     cash.  If an Event of Default specified in Section 501(4) or 501(5) occurs,
     an amount equal to the issue price of all the STRYPES shall automatically,
     and without any declaration or other action on the part of the Trustee or
     any Holder, become immediately due and payable in cash.

     At any time after such a declaration of acceleration has been made or an
     Event of Default specified in Section 501(4) or 501(5) has occurred, and
     before a judgment or decree for payment of the money due has been obtained
     by the Trustee as hereinafter provided, the Holders of a majority of the
     aggregate issue price of the Outstanding STRYPES, by written notice to the
     Company and the Trustee, may rescind and annul such declaration or Event of
     Default and its consequences if

          (1) the Company has paid or deposited with the Trustee a sum
          sufficient to pay

               (A) all overdue installments of interest on all STRYPES,

               (B) to the extent that payment of such interest is lawful,
               interest upon overdue installments of interest at the rate borne
               by the STRYPES, and

               (C) all sums paid or advanced by the Trustee hereunder and the
               reasonable compensation, expenses, disbursements and advances of
               the Trustee, its agents and counsel,

          and

          (2) all Events of Default with respect to the STRYPES, other than the
          non-payment of the amount equal to the issue price of all the STRYPES
          due solely by reason of such declaration of acceleration or Event of
          Default

                                       16

          specified in Section 501(4) or 501(5), have been cured or waived as
          provided in Section 513.

     No such rescission shall affect any subsequent default or impair any right
     consequent thereon."

     (d)   By deleting the first paragraph of Section 503 of the Principal
Indenture in its entirety and inserting in its stead the following:

          "The Company covenants that, if default is made in the payment of any
     installment of interest on any STRYPES (other than interest due on the
     Maturity Date) when such interest becomes due and payable and such default
     continues for a period of 30 days, the Company will, upon demand of the
     Trustee, pay to it, for the benefit of the Holders of such STRYPES, an
     amount equal to the issue price of all the STRYPES, the whole amount of
     interest then due and payable on such STRYPES and, to the extent that
     payment of such interest shall be legally enforceable, interest on any
     overdue interest, at the rate borne by the STRYPES, and, in addition
     thereto, such further amount as shall be sufficient to cover the costs and
     expenses of collection, including the reasonable compensation, expenses,
     disbursements and advances of the Trustee, its agents and counsel.

          The Company further covenants that, if the Maturity Consideration or
     any interest due on the Maturity Date is not delivered or paid in respect
     of any STRYPES on the Maturity Date, the Company will, upon demand of the
     Trustee, pay to it, for the benefit of the Holders of such STRYPES, the
     Maturity Consideration then due and payable on such STRYPES, the whole
     amount of interest then due and payable on such STRYPES and, to the extent
     that payment of such interest shall be legally enforceable, interest on any
     Maturity Consideration that is overdue and on any overdue interest, at the
     rate borne by the STRYPES, and, in addition thereto, such further amount as
     shall be sufficient to cover the costs and expenses of collection,
     including the reasonable compensation, expenses, disbursements and advances
     of the Trustee, its agents and counsel."

     Trustee pursuant to this Article shall be applied in the following order,
     at the date or dates fixed by the Trustee and, in case of the distribution
     of such money on account of the Maturity Consideration or interest, upon
     presentation of the relevant STRYPES Certificate and the notation thereon
     of the payment if only partially paid and upon surrender thereof if fully
     paid:

     STRYPES in respect of which or for the benefit of which such money has been
     collected, ratably, without preference or priority of any kind, according
     to the amounts due and payable on such STRYPES; and

          THIRD: The balance, if any, to the Person or Persons entitled
     thereto."

     (f)   By deleting Section 508 of the Principal Indenture in its entirety
and inserting in its stead the following:

     Indenture, the Holder of any STRYPES shall have the right, which is
     absolute and unconditional, to receive (subject to Section 502) payment of
     the Maturity Consideration in respect of and (subject to Sections 305 and
     307) interest on such STRYPES and to institute suit for the enforcement of
     any such payment, and such right shall not be impaired without the consent
     of such Holder."

Indenture in its entirety and inserting in its stead the following:

     "The Holders of not less than a majority of the aggregate issue price of
     the Outstanding STRYPES may on behalf of the Holders of all STRYPES waive
     any past default hereunder and its consequences, except a default

          (1) in the delivery or payment of the Maturity Consideration or in the
     payment of interest on any STRYPES, or

          (2) in respect of a covenant or provision hereof which under Article
     Nine cannot be modified or amended without the consent of the Holder of
     each Outstanding STRYPES affected."

and inserting in its stead the following:

     "SECTION 801.  Consolidations and Mergers of the Company and Sales, Leases
     and Conveyances Permitted Subject to Certain Conditions.  The Company may
     consolidate with, or sell, lease or convey all or substantially all of its
     assets to, or merge with or into any other corporation, provided that in
     any such case, (i) either the Company shall be the continuing corporation,

     observance of all of the covenants and conditions of this Indenture to be
     performed by the Company by supplemental indenture satisfactory to the
     Trustee, executed and delivered to the Trustee by such corporation, and
     (ii) the Company or such successor corporation, as the case may be, shall

     in any manner or eliminating any of the provisions of this Indenture or of
     modifying in any manner the rights of the Holders of STRYPES under this
     Indenture; provided, however, that no such supplemental indenture shall,
     without the consent of the Holder of each Outstanding STRYPES affected
     thereby,

     of interest on any STRYPES, or reduce the amount of Maturity Consideration
     deliverable or payable on the Maturity Date or reduce the amount of

     Consideration in respect of, and interest on, the STRYPES in accordance
     with the terms of the STRYPES and this Indenture."

     (k)   By deleting Section 1003 of the Principal Indenture in its entirety
and inserting in its stead the following:

     "SECTION 1003.  Money for Security Payments to Be Held in Trust.  If the
     Company shall at any time act as its own Paying Agent, it will, on or
     before each due date of the Maturity Consideration in respect of, or
     interest on, any of the STRYPES, segregate and hold in trust for the
     benefit of the Persons entitled thereto consideration in an amount
     sufficient to deliver or pay the Maturity Consideration or a sum sufficient
     to pay the interest so becoming due until such consideration shall be
     delivered or paid to such Persons or otherwise disposed of as herein
     provided and will promptly notify the Trustee of its action or failure so
     to act.

     Whenever the Company shall have one or more Paying Agents, it will, prior
     to each due date of the Maturity Consideration in respect of, or interest
     on, any STRYPES, deposit with a Paying Agent consideration in an amount
     sufficient to deliver or pay the Maturity Consideration or a sum sufficient
     to pay the interest so becoming due, such consideration to be held as
     provided by the Trust Indenture Act, and (unless such Paying Agent is the
     Trustee) the Company will promptly notify the Trustee of its action or
     failure so to act.

     The Company will cause each Paying Agent other than the Trustee to execute
     and deliver to the Trustee an instrument in which such Paying Agent shall
     agree with the Trustee, subject to the provisions of this Section, that
     such Paying Agent will (i) comply with the provisions of the Trust
     Indenture Act applicable to it as Paying Agent and (ii) during the
     continuance of any default by the Company (or any other obligor upon the
     STRYPES) in the making of any payment

     in respect of the STRYPES, upon the written request of the Trustee,
     forthwith pay to the Trustee all sums held in trust by such Paying Agent as
     such.

     The Company may at any time, for any purpose, pay, or by Company Order
     direct any Paying Agent to pay, to the Trustee all sums held in trust by
     the Company or such Paying Agent, such sums to be held by the Trustee upon
     the same trusts as those upon which such sums were held by the Company or
     such Paying Agent; and, upon such payment by any Paying Agent to the
     Trustee, such Paying Agent shall be released from all further liability
     with respect to such money.

     Any consideration deposited with the Trustee or any Paying Agent, or then
     held by the Company, in trust for the payment of the interest on or
     delivery upon discharge of any STRYPES and remaining unclaimed for two
     years after such consideration has become due and payable shall be paid to
     the Company on Company Request, or (if then held by the Company) shall be
     discharged from such trust; and the Holder of such STRYPES shall
     thereafter, as an unsecured general creditor, look only to the Company for
     payment thereof, and all liability of the Trustee or such Paying Agent with
     respect to such trust consideration, and all liability of the Company as
     trustee thereof, shall thereupon cease; provided, however, that the Trustee
     or such Paying Agent, before being required to make any such repayment, may
     at the expense of the Company cause to be published once, in an Authorized
     Newspaper in each Place of Payment or to be mailed to Holders of the
     STRYPES, or both, notice that such consideration remains unclaimed and
     that, after a date specified therein, which shall not be less than 30 days
     from the date of such publication or mailing, any unclaimed balance of such
     consideration then remaining will be repaid to the Company."

     Merrill Lynch & Co., Inc., a Delaware corporation (hereinafter called the
"Company", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay and
discharge each STRYPES evidenced hereby on _________, 2001 (the "Maturity Date")
by delivering to _____________________________________, or registered assigns, a
percentage of the amount or number of each type of Reference Security and other
property then constituting part of the Reference Property (as defined below)
determined in accordance with the provisions set forth below, and to pay
interest (computed on the basis of a 360-day year of twelve 30-day months) on
such STRYPES from _______, 1996, or from the most recent Interest Payment Date
to which interest has been paid or duly provided for, on ___________,

Maturity Date, at the rate of __% of the Issue Price per annum, until the
Maturity Date or such earlier date on which the Issue Price is repaid in
accordance with the provisions described below.  The interest so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in said Indenture, be paid to the Person in whose name this STRYPES
Certificate (or one or more Predecessor STRYPES Certificates) is registered at
the close of business on the fifteenth calendar day (whether or not a Business
Day) immediately preceding such Interest Payment Date (each a "Regular Record
Date").  In any case where such Interest Payment Date shall not be a Business
Day, then (notwithstanding any other provision of said Indenture or this STRYPES
Certificate) payment of such interest need not be made on such date, but may be
made on the next succeeding Business Day with the same force and effect as if
made on such date, and, if such payment is so made, no interest shall accrue for
the period from and after such date.  Any such interest not so punctually paid
or duly provided for shall forthwith cease to be payable to the registered
Holder on the relevant Regular Record Date, and may be paid to the Person in
whose name this STRYPES Certificate (or one or more Predecessor STRYPES
Certificates) is registered at the close of business on a Special Record Date
for the payment of such interest to be fixed by the Trustee hereinafter referred
to, notice whereof shall be given to Holders of STRYPES not less than 10 days
prior to such Special Record Date, or may be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the STRYPES may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in said Indenture.

     On the Maturity Date, the Company shall pay and discharge each STRYPES
evidenced hereby by delivering to the Holder:  (a) if the Reference Property
Value (as defined below) is greater than or equal to $____ (the "Threshold
Appreciation Price"), _____% of the amount or number of each type of Reference
Security and other property constituting part of the Reference Property, (b) if
the Reference Property Value is less than the Threshold Appreciation Price but
is greater than $_____ (the "Initial Price"), a percentage of the amount or
number of each type of Reference Security and other property constituting part
of the Reference Property, allocated as proportionately as practicable, so that
the aggregate value thereof is equal to the Initial Price and (c) if the
Reference Property Value is less than or equal to the Initial Price, 100% of the
amount or number of each type of Reference Security and other property
constituting part of the Reference Property.  Notwithstanding the foregoing, the
Company may, at its option in lieu of delivering the applicable percentage of
each type of Reference Security and other property constituting part of the
Reference Property on the Maturity Date, deliver cash in an amount (calculated
to the nearest 1/100th of a dollar per STRYPES or, if there is not a nearest
1/100th of a dollar, then to the next higher 1/100th of a dollar) equal to the

                                       25
<PAGE>
 
sum of (a) for any portion of the Reference Property consisting of cash that is
otherwise deliverable on the Maturity Date, the amount of such cash, (b) for any
portion of the Reference Property consisting of property other than cash or
Reference Securities that is otherwise deliverable on the Maturity Date, the
fair market value (as determined by a nationally recognized independent
investment banking firm retained for this purpose by the Company) as of the
third Trading Day preceding the Maturity Date of such property, and (c) for any
portion of the Reference Property consisting of a Reference Security (including
IMC Common Stock) that is otherwise deliverable on the Maturity Date, an amount
equal to the average Closing Price per unit of such Reference Security on the 20
Trading Days immediately prior to, but not including, the second Trading Day
preceding the Maturity Date multiplied by the number of units of such Reference
Security constituting a part of the Reference Property, all as provided in the
Indenture.  Such number or amount of each type of Reference Security and other
property constituting part of the Reference Property (or, pursuant to the
Company's option, the amount of cash in lieu thereof) deliverable upon payment
and discharge hereof on the Maturity Date is hereinafter referred to as the
"Maturity Consideration."

     The term "Reference Property" initially means one share of common stock,
par value $1.00 per share (the "IMC Common Stock"), of IMC Global Inc., a
Delaware corporation ("IMC Global"), and shall be subject to adjustment from
time to time prior to the Maturity Date to reflect the addition or substitution

Reference Securities, the fair market value (as determined by a nationally
recognized independent investment banking firm retained for this purpose by the
Company) as of the third Trading Day preceding the Maturity Date of such
property, and (c) for any portion of the Reference Property consisting of a
Reference Security (including IMC Common Stock), an amount equal to the average
Closing Price per unit of such Reference Security on the 20 Trading Days
immediately prior to, but not including, the second Trading Day preceding the
Maturity Date multiplied by the number of units of such Reference Security
constituting part of the Reference Property.  The term "Closing Price" means,
with respect to any Reference Security on any date of determination, the closing
sale price (or, if no closing price is reported, the last reported sale price)
of such Reference Security on the NYSE on such date or, if such Reference
Security is not listed for trading on the NYSE on any such date, as reported in
the composite transactions for the principal United

States securities exchange on which such Reference Security is so listed, or if
such Reference Security is not so listed on a United States national or regional
securities exchange, as reported by the National Association of Securities
Dealers, Inc. Automated Quotation System, or, if such Reference Security is not
so reported, the last quoted bid price for such Reference Security in the over-
the-counter market as reported by the National Quotation Bureau or similar
organization, or, if such bid price is not available, the market value of such
Reference Security on such date as determined by a nationally recognized
independent investment banking firm retained for this purpose by the Company.
The term "Trading Day" means, with respect to any Reference Security the Closing
Price of which is being determined, a day on which such Reference Security (A)
is not suspended from trading on any national or regional securities exchange or
association or over-the-counter market at the close of business and (B) has
traded at least once on the national or regional securities exchange or
association or over-the-counter market that is the primary market for the
trading of such Reference Security.

     Interest on the STRYPES evidenced hereby will be payable, and delivery of
the Maturity Consideration in payment of the STRYPES evidenced hereby on the
Maturity Date will be made, upon surrender of this STRYPES Certificate, at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, The City of New York, and payment of interest on the STRYPES
evidenced by this STRYPES Certificate (and, if the Company elects to deliver
cash in lieu of the applicable percentage of each type of Reference Property on
the Maturity Date, the amount of cash payable on the Maturity Date) will be made
in such coin or currency of the United States of America as at the time of
payment is legal tender for payment of public and private debts; provided,
however, that at the option of the Company payment of interest may be made by
check mailed to the address of the Person entitled thereto as such address shall
appear on the Securities Register.

     ADDITIONAL PROVISIONS OF THIS STRYPES CERTIFICATE ARE CONTAINED ON THE
REVERSE HEREOF AND SUCH PROVISIONS SHALL HAVE THE SAME EFFECT AS THOUGH FULLY
SET FORTH IN THIS PLACE.

     Unless the certificate of authentication hereon has been executed by or on
behalf of the Trustee by manual signature, this STRYPES Certificate shall not be
entitled to any benefit under the Indenture, or be valid or obligatory for any
purpose.

      (Payable with Shares of Common Stock, par value $1.00 per share,  
                              of IMC Global Inc.)


     This STRYPES Certificate evidences part of a duly authorized issue of
unsecured and unsubordinated debentures, notes or other evidences of senior
indebtedness (hereinafter called the "Securities") of the Company of the series
hereinafter specified, all such Securities issued and to be issued under an
indenture dated as of April 1, 1983 and restated as of April 1, 1987, as amended
and supplemented as of _______, 1996, between the Company and Chemical Bank
(successor by merger to Manufacturers Hanover Trust Company), as Trustee (the
indenture dated as of April 1, 1983 and restated as of April 1, 1987, as
amended, restated and supplemented from time to time, the "Indenture"), to which
Indenture and all other indentures supplemental thereto reference is hereby made
for a statement of the rights and limitation of rights thereunder of the Holders
of the Securities and of the rights, obligations, duties and immunities of the
Trustee for each series of Securities and of the Company, and the terms upon
which the Securities are and are to be authenticated and delivered.  As provided
in the Indenture, the Securities may be issued in one or more series, which
different series may be issued in various aggregate principal amounts, may be
denominated in currencies other than U.S. Dollars (including composite
currencies), may mature at different times, may bear interest, if any, at
different rates, may be subject to different redemption provisions, if any, may

in the Indenture provided or permitted.  This STRYPES Certificate evidences
Securities of the series designated as Structured Yield Product Exchangeable for
Stock, __% STRYPES Due ___________, 2001 (each, a "STRYPES").

     The STRYPES are not subject to any sinking fund or other mandatory
redemption provisions.  The STRYPES are not payable at the option of the Holders
prior to the Maturity Date.

     If an Event of Default with respect to the STRYPES, as defined in the
Indenture, shall occur and be continuing, then an amount equal to the issue
price of all the STRYPES may be declared immediately due and payable in cash in
the manner and with the effect provided in the Indenture.

                                       29

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the STRYPES under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of 66-2/3%
of the aggregate issue price of the Outstanding STRYPES.  The Indenture also
contains provisions permitting the Holders of a majority of the aggregate issue
price of the Outstanding STRYPES, on behalf of the Holders of all STRYPES, to
waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences with respect to
the STRYPES.  Any such consent or waiver by the Holder of this Security shall be
conclusive and binding upon such Holder and upon all future Holders of the
STRYPES evidenced by this STRYPES Certificate and of any STRYPES evidenced by a
STRYPES Certificate issued upon the transfer hereof or in exchange herefor or in
lieu hereof whether or not notation of such consent of waiver is made upon this
STRYPES Certificate.

     No reference herein to the Indenture and no provision of this STRYPES
Certificate or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to deliver or pay the interest on,
and Maturity Consideration in respect of, the STRYPES evidenced by this STRYPES
Certificate at the times, place and rate, and in the manner, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the STRYPES evidenced by this STRYPES Certificate are transferable on the
Security Register of the Company, upon surrender of this STRYPES Certificate for
registration of transfer at the office or agency of the Company to be maintained
for that purpose in The City of New York, New York, or at any other office or
agency of the Company maintained for that purpose, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new STRYPES
Certificates, evidencing the same aggregate number of STRYPES, will be issued to
the designated transferee or transferees.

     No service charge shall be made for any such transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection with the registration of such transfer
or exchange, other than certain exchanges not involving any transfer.  Certain
terms used in this STRYPES Certificate which are defined in the Indenture have
the meanings set forth therein.

                         Issue Price Per STRYPES: $____

          Merrill Lynch & Co., Inc., a Delaware corporation (hereinafter called
the "Company", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay and
discharge each STRYPES evidenced hereby on _________, 2001 (the "Maturity Date")
by delivering to _____________________________________________________, or 
registered assigns, a percentage of the amount or number of each type of 
Reference Security and other property then constituting part of the Reference 
Property (as defined below) determined in accordance with the provisions set 
forth below, and to pay interest (computed on the basis of a 360-day year of 
twelve 30-day months) on such STRYPES from _______, 1996, or from the most 
recent Interest Payment Date to
<PAGE>
 
which interest has been paid or duly provided for, on ___________, ___________,
__________ and ___________ in each year, commencing ____________,1996 and on the
Maturity Date, at the rate of __% of the Issue Price per annum, until the
Maturity Date or such earlier date on which the Issue Price is repaid in
accordance with the provisions described below.  The interest so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in said Indenture, be paid to the Person in whose name this STRYPES
Certificate (or one or more Predecessor STRYPES Certificates) is registered at
the close of business on the fifteenth calendar day (whether or not a Business
Day) immediately preceding such Interest Payment Date (each a "Regular Record
Date").  In any case where such Interest Payment Date shall not be a Business
Day, then (notwithstanding any other provision of said Indenture or this STRYPES
Certificate) payment of such interest need not be made on such date, but may be
made on the next succeeding Business Day with the same force and effect as if
made on such date, and, if such payment is so made, no interest shall accrue for
the period from and after such date.  Any such interest not so punctually paid
or duly provided for shall forthwith cease to be payable to the registered
Holder on the relevant Regular Record Date, and may be paid to the Person in
whose name this STRYPES Certificate (or one or more Predecessor STRYPES
Certificates) is registered at the close of business on a Special Record Date
for the payment of such interest to be fixed by the Trustee hereinafter referred
to, notice whereof shall be given to Holders of STRYPES not less than 10 days
prior to such Special Record Date, or may be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the STRYPES may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in said Indenture.

          On the Maturity Date, the Company shall pay and discharge each STRYPES
evidenced hereby by delivering to the Holder:  (a) if the Reference Property
Value (as defined below) is greater than or equal to $____ (the "Threshold
Appreciation Price"), _____% of the amount or number of each type of Reference
Security and other property constituting part of the Reference Property, (b) if
the Reference Property Value is less than the Threshold Appreciation Price but
is greater than $_____ (the "Initial Price"), a percentage of the amount or
number of each type of Reference Security and other property constituting part
of the Reference Property, allocated as proportionately as practicable, so that
the aggregate value thereof is equal to the Initial Price and (c) if the
Reference Property Value is less than or equal to the Initial Price, 100% of the
amount or number of each type of Reference Security and other property
constituting part of the Reference Property.  Notwithstanding the foregoing, the
Company may, at its option in lieu of delivering the applicable percentage of
each type of Reference Security and other property constituting part of the
Reference Property on the Maturity Date, deliver cash in an amount (calculated
to the nearest 1/100th of a dollar per STRYPES or, if there is not a nearest
1/100th of a dollar, then to the next higher 1/100th of a dollar) equal to the
sum of (a) for any portion of the Reference Property consisting of cash that is
otherwise deliverable on the Maturity Date, the amount of such cash, (b) for any
portion of the Reference Property consisting of property other than cash or
Reference Securities that is otherwise deliverable on the Maturity Date, the
fair market value (as determined by a nationally recognized independent
investment banking firm retained for this purpose by the Company) as of the
third Trading Day preceding the Maturity Date of such property, and (c) for any
portion of the Reference Property consisting of a Reference Security (including
IMC Common Stock) that is otherwise deliverable on the Maturity Date, an amount
equal to the average Closing Price per unit of such Reference Security on the

                                       2
<PAGE>
 
20 Trading Days immediately prior to, but not including, the second Trading Day
preceding the Maturity Date multiplied by the number of units of such Reference
Security constituting a part of the Reference Property, all as provided in the
Indenture.  Such number or amount of each type of Reference Security and other
property constituting part of the Reference Property (or, pursuant to the
Company's option, the amount of cash in lieu thereof) deliverable upon payment
and discharge hereof on the Maturity Date is hereinafter referred to as the
"Maturity Consideration."

          The term "Reference Property" initially means one share of common
stock, par value $1.00 per share (the "IMC Common Stock"), of IMC Global Inc., a
Delaware corporation ("IMC Global"), and shall be subject to adjustment from
time to time prior to the Maturity Date to reflect the addition or substitution
of any cash, securities and/or other property as provided for in the Indenture.
The term "Reference Security" means, at any time, any security (as defined in
Section 2(1) of the Securities Act of 1933, as amended) then constituting part
of the Reference Property.  The term "Reference Property Value" means, subject
to the provisions of the Indenture, the sum of (a) for any portion of the
Reference Property consisting of cash, the amount of such cash, (b) for any
portion of the Reference Property consisting of property other than cash or
Reference Securities, the fair market value (as determined by a nationally
recognized independent investment banking firm retained for this purpose by the
Company) as of the third Trading Day preceding the Maturity Date of such
property, and (c) for any portion of the Reference Property consisting of a
Reference Security (including IMC Common Stock), an amount equal to the average
Closing Price per unit of such Reference Security on the 20 Trading Days
immediately prior to, but not including, the second Trading Day preceding the
Maturity Date multiplied by the number of units of such Reference Security
constituting part of the Reference Property.  The term "Closing Price" means,
with respect to any Reference Security on any date of determination, the closing
sale price (or, if no closing price is reported, the last reported sale price)
of such Reference Security on the NYSE on such date or, if such Reference
Security is not listed for trading on the NYSE on any such date, as reported in
the composite transactions for the principal United States securities exchange
on which such Reference Security is so listed, or if such Reference Security is
not so listed on a United States national or regional securities exchange, as
reported by the National Association of Securities Dealers, Inc. Automated
Quotation System, or, if such Reference Security is not so reported, the last
quoted bid price for such Reference Security in the over-the-counter market as
reported by the National Quotation Bureau or similar organization, or, if such
bid price is not available, the market value of such Reference Security on such
date as determined by a nationally recognized independent investment banking
firm retained for this purpose by the Company.  The term "Trading Day" means,
with respect to any Reference Security the Closing Price of which is being
determined, a day on which such Reference Security (A) is not suspended from
trading on any national or regional securities exchange or association or over-
the-counter market at the close of business and (B) has traded at least once on
the national or regional securities exchange or association or over-the-counter
market that is the primary market for the trading of such Reference Security.

          Interest on the STRYPES evidenced hereby will be payable, and delivery
of the Maturity Consideration in payment of the STRYPES evidenced hereby on the
Maturity Date will be made, upon surrender of this STRYPES Certificate, at the
office or agency of the Company maintained

for that purpose in the Borough of Manhattan, The City of New York, and payment
of interest on the STRYPES evidenced by this STRYPES Certificate (and, if the
Company elects to deliver cash in lieu of the applicable percentage of each type
of Reference Property on the Maturity Date, the amount of cash payable on the
Maturity Date) will be made in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that at the option of the Company payment of
interest may be made by check mailed to the address of the Person entitled
thereto as such address shall appear on the Securities Register.

          ADDITIONAL PROVISIONS OF THIS STRYPES CERTIFICATE ARE CONTAINED ON THE
REVERSE HEREOF AND SUCH PROVISIONS SHALL HAVE THE SAME EFFECT AS THOUGH FULLY

(Payable with Shares of Common Stock, par value $1.00 per share, of IMC Global
Inc.)


     This STRYPES Certificate evidences part of a duly authorized issue of
unsecured and unsubordinated debentures, notes or other evidences of senior
indebtedness (hereinafter called the "Securities") of the Company of the series
hereinafter specified, all such Securities issued and to be issued under an
indenture dated as of April 1, 1983 and restated as of April 1, 1987, as amended
and supplemented as of _______, 1996, between the Company and Chemical Bank
(successor by merger to Manufacturers Hanover Trust Company), as Trustee (the
indenture dated as of April 1, 1983 and restated as of April 1, 1987, as
amended, restated and supplemented from time to time, the "Indenture"), to which
Indenture and all other indentures supplemental thereto reference is hereby made
for a statement of the rights and limitation of rights thereunder of the Holders
of the Securities and of the rights, obligations, duties and immunities of the
Trustee for each series of Securities and of the Company, and the terms upon
which the Securities are and are to be authenticated and delivered.  As provided
in the Indenture, the Securities may be issued in one or more series, which
different series may be issued in various aggregate principal amounts, may be
denominated in currencies other than U.S. Dollars (including composite
currencies), may mature at different times, may bear interest, if any, at
different rates, may be subject to different redemption provisions, if any, may
be subject to different sinking, purchase and analogous funds, if any, may be
subject to different covenants and Events of Default and may otherwise vary as
in the Indenture provided or permitted.  This STRYPES Certificate evidences
Securities of the series designated as Structured Yield Product Exchangeable for
Stock, __% STRYPES Due ___________, 2001 (each, a "STRYPES").

     The STRYPES are not subject to any sinking fund or other mandatory
redemption provisions.  The STRYPES are not payable at the option of the Holders
prior to the Maturity Date.

     If an Event of Default with respect to the STRYPES, as defined in the
Indenture, shall occur and be continuing, then an amount equal to the issue
price of all the STRYPES may be declared immediately due and payable in cash in
the manner and with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the STRYPES under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of 66-2/3%
of the aggregate issue price of the Outstanding STRYPES.  The Indenture also
contains provisions permitting the Holders of a

                                       6
<PAGE>
 
majority of the aggregate issue price of the Outstanding STRYPES, on behalf of
the Holders of all STRYPES, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences with respect to the STRYPES.  Any such consent or waiver by
the Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of the STRYPES evidenced by this STRYPES Certificate and
of any STRYPES evidenced by a STRYPES Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
consent of waiver is made upon this STRYPES Certificate.

     No reference herein to the Indenture and no provision of this STRYPES
Certificate or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to deliver or pay the interest on,
and Maturity Consideration in respect of, the STRYPES evidenced by this STRYPES
Certificate at the times, place and rate, and in the manner, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the STRYPES evidenced by this STRYPES Certificate are transferable on the
Security Register of the Company, upon surrender of this STRYPES Certificate for
registration of transfer at the office or agency of the Company to be maintained
for that purpose in The City of New York, New York, or at any other office or
agency of the Company maintained for that purpose, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new STRYPES
Certificates, evidencing the same aggregate number of STRYPES, will be issued to
the designated transferee or transferees.

     No service charge shall be made for any such transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection with the registration of such transfer
or exchange, other than certain exchanges not involving any transfer.  Certain
terms used in this STRYPES Certificate which are defined in the Indenture have
the meanings set forth therein.

     This STRYPES Certificate shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York.  The Company,
the Trustee and any agent of the Company or the Trustee may treat the Person in
whose name this STRYPES Certificate is registered as the owner of the STRYPES
evidenced hereby for the purpose of receiving payment as herein provided and for
all other purposes, whether or not the STRYPES be overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

Merrill Lynch & Co., Inc.
World Financial Center
North Tower
New York, New York  10281-1334

Gentlemen:

          We have acted as your counsel and are familiar with the corporate
proceedings had in connection with the proposed issuance and sale by Merrill
Lynch & Co., Inc. (the "Company") of up to 6,510,286 of its Structured Yield
Product Exchangeable for Stock, _____% STRYPES Due _________, 2001 (the
"Securities").

           We have examined such documents and records as we deemed appropriate,
including the following:

          (a) a copy of the Restated Certificate of Incorporation of the
     Company, certified by the Secretary of State of the State of Delaware;

          (b) a copy of the Company's Registration Statement on Form S-3 (File
     No. 33-65135), as amended by Post-Effective Amendment Nos. 3 and 5 thereto,
     relating to the Securities (as so amended, the "Registration Statement");

          (c) a copy of the indenture with respect to the Company's senior debt
     securities between the Company and Chemical Bank (successor by merger to
     Manufacturers Hanover Trust Company), as trustee (the "Trustee"), dated as
     of April 1, 1983, as amended and restated (the "Principal Indenture"), in
     the form executed by the Company and the Trustee; and

          (d) a copy of the supplemental indenture with respect to the
     Securities between the Company and the Trustee (the "Supplemental
     Indenture"), in the form filed as an exhibit to the Registration Statement.

     The term "Indenture" shall mean the Principal Indenture as amended by the
Trust Indenture Reform Act of 1990 and as amended and supplemented by the
Supplemental Indenture.

     Based upon the foregoing and upon such further investigation as we deem
relevant in the premises, we are of the opinion:

     1.   The Company has been duly incorporated under the laws of the State of
Delaware.
<PAGE>
 
     2.  The Principal Indenture has been duly and validly authorized, executed
and delivered by the Company and, as amended by the Trust Indenture Reform Act
of 1990, constitutes a valid and binding agreement of the Company, enforceable
in accordance with its terms.

     3.   The Supplemental Indenture has been duly authorized by the Company
and, when the Supplemental Indenture has been duly executed and delivered by the
Company and the Trustee, such Supplemental Indenture will constitute a valid and
binding agreement of the Company, enforceable in accordance with its terms.

     4.   When appropriate corporate action has been taken to fix the terms of
the Securities and the Supplemental Indenture has been duly executed and
delivered by the Company and the Trustee, and when the Securities shall have
been duly authenticated or countersigned by the Trustee and duly issued under
the Indenture, such Securities will constitute valid and binding obligations of
the Company, enforceable in accordance with their terms.

     With respect to enforcement, the above opinions are qualified to the extent
that enforcement of the Principal Indenture, the Supplemental Indenture or the
Securities may be limited by bankruptcy, insolvency (including, without
limitation, all laws relating to fraudulent transfers), reorganization,
moratorium or other similar laws affecting enforcement of creditors' rights
generally and may be subject to general principles of equity (regardless of
whether enforcement is considered in a proceeding in equity or at law).

     We consent to the filing of this opinion as an exhibit to the Registration
Statement, to the quotation in the Registration Statement of our opinion with
respect to certain tax matters and to the use of our name wherever appearing in
the Registration Statement and any amendment thereto.

                                    Very truly yours,



                                    /s/ BROWN & WOOD

practicable, Seller will deliver fractional interests of any Reference Property
other than cash or a Reference Security at the Closing.  If such delivery is not
practicable, in lieu of any fractional interest of any Reference Property other
than cash or a Reference Security which would otherwise be deliverable at the
Closing, Seller shall make a cash payment in respect of such fractional interest
in an amount equal to the value of such fractional interest based on the fair
market value (as determined by a nationally recognized independent investment
banking firm retained for this purpose by ML & Co.) as of the third Trading Day
preceding the Maturity Date of such Reference Property other than cash or a
Reference Security.

     2.5. Cash Settlement.  (a)  Notwithstanding the provisions of Sections 2.1,

discretion, to require that its obligation contained therein be settled, in
whole, through a cash payment at Closing in lieu of delivery of the Contract
Consideration.  The amount of such cash settlement payment shall be equal to the
value of the Subsidiary Maturity Consideration determined in accordance with the
second sentence of the third paragraph of the Subsidiary STRYPES, assuming (x)
(1) all of the STRYPES are held by the same Holder at such time and without
taking into account any default with respect to the STRYPES or any acceleration
of the maturity of the STRYPES resulting therefrom and (2) all of the Subsidiary
STRYPES are held by the same Holder at such time and without taking into account

shall notify Purchaser whether it will exercise its option to require cash
settlement pursuant to this Section 2.5.

     (b) If the Contract Consideration consists of securities and/or other
property other than IMC Common Stock, Seller's right to deliver (or cause to be
delivered) to Purchaser hereunder such securities and/or other property shall be
conditioned upon such securities and/or other property so delivered (i) being
transferable by Purchaser to the same extent as when received by or on behalf of
Seller, and (ii) not being subjected, by reason of or following receipt

                                       4

     (e) Except for Permitted Activities and the transactions otherwise
contemplated by this Agreement and the Pledge Agreement, own any property, incur
any liabilities, make any investment or conduct any business other than the
ownership of the Collateral, this Agreement and the Pledge Agreement, and the
incurrence of the obligations pursuant to this Agreement and the Pledge
Agreement.

     5.4.  Separate Corporate Existence.  Seller acknowledges that Purchaser is
           ----------------------------                                        
entering into the transactions contemplated by this Agreement and the Pledge
Agreement in reliance upon the Seller's identity as a legal entity that is
separate from GAMI and its other Affiliates. As used in this Agreement, unless
otherwise specifically provided, the term "Affiliate" means, as to any Person,
any other Person that, directly or indirectly, controls, is controlled by or is
under common control with such Person or is a partner in, or a director or
officer of, such Person. The term "control" (including the terms "controlled by"
or "under the common control with") means the possession, direct or indirect, of
the power to vote ten percent or more of the securities having ordinary voting
power for the election of directors of such Person or to direct or cause the
direction of the management and policies of such Person, whether through
ownership of voting securities or by contract or otherwise. Therefore, from and
after the date of execution and delivery of this Agreement, Seller covenants and
agrees to take all reasonable steps, including, without limitation, all steps
that Purchaser may from time to time reasonably request, to maintain Seller's
identity as a separate legal entity and to make it manifest to third parties
that Seller is an entity with assets and liabilities distinct from those of GAMI
and its other Affiliates and not just a division of GAMI. Without limiting the
generality of the foregoing and in addition to the other covenants set forth
herein, Seller covenants and agrees to:

     (a) conduct its own business in its own name and, to the extent Seller has
any full-time employees, require that all full-time employees of the Seller
identify themselves as such and not as employees of any Affiliate (including,
without limitation, by means of providing appropriate employees with business or
identification cards identifying such employees as Seller's employees);

     (b) compensate all employees, consultants and agents directly, from
Seller's bank accounts, for services provided to Seller by such employees,
consultants and agents, except to the extent that any employee, consultant or
agent of Seller is also an employee, consultant or agent of any Affiliate(s) and
the compensation of such employee, consultant or agent is allocated between
Seller and such Affiliate(s) on a basis which reflects the services rendered to
Seller and such Affiliate(s);

     (c) have separate stationery, invoices and checks in its own name;

     (d) conduct all transactions with each Affiliate strictly on an arm's-
length basis, allocate all overhead expenses (including, without limitation,
telephone and other utility charges)

                                       10
<PAGE>
 
for items shared between Seller and such Affiliate on the basis of actual use to
the extent practicable and, to the extent such allocation is not practicable, on
a basis reasonably related to actual use;

     (e) observe all corporate formalities as a distinct entity, and ensure that
all appropriate corporate actions are duly authorized by its Board of Directors;
without limiting the generality of the foregoing, Seller's Certificate of
Incorporation shall at all times provide that corporate action to file a
voluntary petition under the federal Bankruptcy Code or consent to the entry of
an order for relief in an involuntary case under the federal bankruptcy laws as
now or hereafter in effect may be authorized only by unanimous vote of its Board
of Directors;

     (f) maintain the Seller's books and records separate from those of each
Affiliate and otherwise readily identifiable as its own assets rather than
assets of any Affiliate;

     (g) prepare its financial statements separately from those of each
Affiliate and insure that any consolidated statements of any Affiliate that
include Seller have notes clearly indicating that Seller is a separate corporate
entity and that the Collateral will be available first and foremost to satisfy 
the claims of Purchaser pursuant to this Agreement;

     (h) except as herein specifically otherwise provided, not commingle funds
or other assets, including the Collateral, of Seller with those of any Affiliate
and not maintain bank accounts or other depository accounts to which any
Affiliate is an account party, into which any Affiliate makes deposits or from
which any Affiliate has the power to make withdrawals;

     (i) not permit any Affiliate to pay any of the Seller's operating expenses
(except pursuant to allocation arrangements that comply with the requirements of
this Section 5.4);

     (j) except for the master or blanket policies covering Seller and any
Affiliate(s) or the property of Seller and such Affiliate(s), the costs of which
are allocated between Seller and such Affiliate(s) on a reasonable basis, not
permit Seller to be named as an insured on the insurance policy covering the
property of any Affiliate or enter into an agreement with the holder of such
policy whereby in the event of a loss in connection with such property, proceeds
are paid to Seller; and

     (k) have at least one member of its Board of Directors who is not (i) an
officer or employee of any Affiliate; (ii) a Person related to any officer or
employee of any Affiliate, (iii) a holder (directly or indirectly) of any
securities of any Affiliate, or (iv) a Person related to a holder (directly or
indirectly) of any voting securities of any Affiliate; provided that for
                                                       --------         
purposes of this clause (k), "Affiliate" shall mean any entity consolidated
under generally accepted accounting principles with Equity Holdings Limited, an
Illinois limited partnership ("EHL") and any trustee, officer, employee or
direct beneficiary of any of EHL's general partners.

     5.5.  Taxes.  Seller shall pay any and all documentary, stamp, transfer or
           -----                                                               
similar taxes and charges that may be payable in respect of the transfer and
delivery of the Contract Consideration pursuant hereto.

     5.6.  Amounts Due to Trustee.  ML & Co. shall pay any and all amounts due
           ----------------------                                             
to the Trustee under Section 607 of the Indenture.

     5.7.  Certain Notices.  (a)  ML & Co. shall notify Seller of any notice of
           ---------------                                                     
default with respect to the STRYPES received by ML & Co. from the Trustee or any
holders of STRYPES pursuant to the Indenture as promptly as reasonably
practicable after receipt thereof.

     (b) In case at any time while any of the STRYPES are outstanding Seller
receives written notice in its capacity as a holder of any Reference Security
that:

               (i) an issuer of a Reference Security shall declare a dividend
     (or any other distribution) on or in respect of such Reference Security to
     which Section 303(c) of the Supplemental Indenture shall apply (other than
     any cash dividends, if any, paid from time to time by the issuer of such
     Reference Security that do not constitute Extraordinary Cash Dividends);

               (ii) an issuer of a Reference Security shall authorize the
     issuance to all holders of such Reference Security of rights or warrants to
     subscribe for or purchase units of such Reference Security or of any other
     subscription rights or warrants;

               (iii)  there shall occur any conversion or reclassification of
     any Reference Security (other than a subdivision or combination of
     outstanding units of such Reference Security) or any consolidation, merger
     or reorganization to which an issuer of a Reference Security is a party and
     for which approval of any unitholders of such issuer is required, or the
     sale or transfer of all or substantially all of the assets of an issuer of
     a Reference Security; or

               (iv) there shall occur the voluntary or involuntary dissolution,
     liquidation, winding up or bankruptcy of an issuer of a Reference Security;

then Seller shall promptly notify Purchaser and ML & Co. of such fact and of (x)
the date, if known by Seller, on which a record is to be taken for the purpose
of such dividend, distribution or grant of rights or warrants, or, if a record
is not to be taken, the date as of which the holders of such Reference Security
of record to be entitled to such dividend, distribution or grant of rights or
warrants are to be determined, or (y) the date, if known by Seller, on which
such reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation, winding up or bankruptcy is expected to become effective.

     5.8. No Supplemental Indentures Without Consent.  ML & Co. shall not,
          ------------------------------------------                      
without the consent of Seller, enter into any indenture supplemental to the
Indenture or otherwise modify or supplement the Supplemental Indenture which
would have an adverse effect on Seller.  ML & Co. and Purchaser shall not,
without the consent of Seller, amend the Subsidiary STRYPES in any respect that
would adversely affect any obligation of Seller hereunder, including, without
limitation, increasing the consideration that Seller is obligated to deliver at
Closing pursuant to this Agreement.  In the event that (i) any modification or
indenture supplemental to the Indenture or modification or supplement to the
Supplemental Indenture which would have an adverse effect on Seller is entered
into without Seller's consent or (ii) the Subsidiary STRYPES are amended

                                       12
<PAGE>
 
in any respect that would adversely affect any obligation of Seller hereunder
without Seller's consent, then, insofar as this Agreement is concerned and
except to the extent thereafter approved by Seller, this Agreement shall be
interpreted and performed as if such modification or indenture supplemental to
the Indenture or modification or supplement to the Supplemental Indenture or
amendment of the Subsidiary STRYPES had never existed and such modification or
indenture supplemental to the Indenture or modification or supplement to the
Supplemental Indenture or amendment of the Subsidiary STRYPES shall have no
effect for purposes of this Agreement.

     5.9. Limitations on Trading During Certain Days.  Each of Seller and ML &
          ------------------------------------------                          
Co. hereby agrees that it will not, and it will cause each of its Affiliates not
to, buy or sell shares of any Reference Security for their own account during
the 20 Trading Days immediately prior to the second Trading Day preceding the
Maturity Date.

     5.10.  Payment and Discharge of STRYPES.  Purchaser agrees that it shall
            --------------------------------                                 
pay and discharge its obligations under the Subsidiary STRYPES by delivering to
the holders of the Subsidiary STRYPES on the Maturity Date the form of
consideration that it receives from Seller hereunder.  ML & Co. agrees that it
shall pay and discharge its obligations under the STRYPES by delivering to the
holders of the STRYPES on the Maturity Date the form of consideration that it
receives from Purchaser under the Subsidiary STRYPES.

     5.11.  Further Assurances.  From time to time on and after the date hereof
            ------------------                                                 
through the date of Closing, each of the parties hereto shall use its reasonable
best efforts to take, or cause to be taken, all action and to do, or cause to be
done, all things necessary, proper and advisable to consummate and make
effective as promptly as practicable the transactions contemplated by this
Agreement in accordance with the terms and conditions hereof, including (i)
using reasonable best efforts to remove any legal impediment to the consummation
of such transactions and (ii) the execution and delivery of all such deeds,
agreements, assignments and further instruments of transfer and conveyance
necessary, proper or advisable to consummate and make effective the transactions
contemplated by this Agreement in accordance with the terms and conditions
hereof.

Pledge Agreement, shall occur following the occurrence of a ML Termination
Event, within the meaning of the Pledge Agreement, or a GVI Termination Event

is greater than $ [the aggregate Issue Price], then the greater of (x) a
percentage of the amount or number of each type of Reference Security and other
property then constituting Reference Property, allocated

<PAGE>
 
as proportionately as practicable, so that the aggregate value thereof
(determined in the manner provided in Section 2.5 hereof for the Maturity Value)
is equal to $ [the aggregate Issue Price], and (y) ___% of the amount or number
of each type of Reference Security and other property then constituting
Reference Property, or (2) if the value of the Collateral is less than or equal
to $ [the aggregate Issue Price], then 100% of the Collateral, and (iii) the
balance of the Collateral remaining after the delivery and payment described in
clause (ii) above, if any, shall be retained by Seller (and shall become
immediately deliverable by the Agent under the Pledge Agreement to Seller).

     (b)  If a GVI Termination Event, within the meaning of the Pledge
Agreement, shall occur prior to the occurrence of a ML Termination Event, within
the meaning of the Pledge Agreement, then (i) Seller's rights under Section 2.5
hereof shall terminate immediately and (ii) all Collateral shall become
immediately deliverable and payable by Seller to Purchaser (and immediately
deliverable by the Agent under the Pledge Agreement to Purchaser).

          ----------------------------------------------------------------     
& Co. shall provide Seller with all notices given by ML & Co. pursuant to
Section 305 of the Supplemental Indenture. ML & Co. shall provide Seller
reasonable opportunity to review the calculations pertaining to any adjustment
of the Reference Property or to any determination of the Maturity Consideration
or the value of the Maturity Consideration made pursuant to Article Three of the
Supplemental Indenture. If the Seller disagrees with any such calculation or
determination or with the determination of the Subsidiary Maturity
Consideration, the Contract Consideration or the Maturity Value, _________ or
such other independent accounting or investment banking firm agreed upon by
Seller and ML & Co. shall be retained to make such calculation, which shall be
binding upon Purchaser, ML & Co. and Seller. The fees and expenses of such firm
shall be borne by Seller if the independent firm agrees with the calculation of
ML & Co. and shall by borne by ML & Co. if the independent firm agrees with the
calculation of Seller. If the independent firm agrees with neither the
calculation of ML & Co. or of Seller, its fees and expenses shall be borne
equally by ML & Co. and Seller. If, pursuant to the terms and conditions of the
Supplemental Indenture and the STRYPES, ML & Co. shall be required to retain a
nationally recognized independent investment banking firm for any purpose
provided in the Supplemental Indenture or the STRYPES, such nationally
recognized independent investment banking firm shall be selected and retained by
ML & Co. only after giving Seller 30 days prior notice (or such shorter notice
as may be reasonably practicable) of the identity of such firm and after
consultation with Seller, and ML & Co. shall not select any firm that is not
reasonably acceptable to Seller. In the event that ML & Co. fails or refuses to
timely make the calculations pertaining to any adjustment of the Reference
Property or to any determination of the Maturity Consideration or the value of
the Maturity Consideration pursuant to Article Three of the Supplemental
Indenture or to notify Seller of such calculations, then Seller may retain
___________________ or a nationally recognized independent investment banking
firm to make such calculations, adjustments or determinations, which shall be

Co. or, in the case of a waiver, by the party against whom the waiver is to be
