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 $38.25 per STRYPES, or $249,018,440 in the aggregate, except for STRYPES evidenced by STRYPES Certificates authenticated and delivered upon 5 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 July 1, 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 $2.3908 per STRYPES per annum (or $.5977 per STRYPES per quarter), from July 9, 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 January 1, April 1, July 1 and October 1, beginning October 1, 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 appear in the Security Register. The STRYPES shall not be redeemable at the option of the Company, or payable at the option of the Holders, prior to the Maturity Date. The STRYPES shall be issuable only in registered form without coupons. The STRYPES will be issued in any whole numbers. No fractional STRYPES or scrip representing fractional STRYPES shall be issued. SECTION 202. Form of STRYPES. The STRYPES shall be evidenced by --------------- certificates ("STRYPES Certificates") in the form attached hereto as Exhibit A. 6 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 $46.28 (the "Threshold Appreciation Price"), 82.65% 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 $38.25 (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, including the preferred stock purchase right associated therewith, 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. 7 To the extent practicable, the Company will deliver fractional interests of any Reference Property other than cash or 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 8 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 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 9 purchase any of its securities or other property (excluding any rights or warrants referred to in subsection (b) above) (any of 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 10 (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, 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 of such property (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, 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 11 (iv) there shall occur the voluntary or involuntary dissolution, liquidation, winding up or bankruptcy of an issuer of a Reference Security; then the Company shall promptly cause to be delivered to the Trustee and any applicable Paying Agent and filed at the office or agency maintained for the purpose of payment and discharge of STRYPES on the Maturity Date in the Borough of Manhattan, The City of New York by the Trustee (or any applicable Paying Agent), and shall promptly cause to be mailed to the Holders of STRYPES at their last addresses as they shall appear in the Security Register, at least 10 days before the date hereinafter specified (or the earlier of the dates hereinafter specified, in the event that more than one is specified), a notice stating (x) the date, if known by the Company, 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 the Company, on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation, winding up or bankruptcy is expected to become effective.

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 Reference Property 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 13 currently in income payments denominated as interest that are made with respect to the STRYPES in accordance with such Holder's regular method of tax accounting and to treat the Debt Instrument as having been issued with original issue discount in an amount equal to 3.15% of the issue price of the STRYPES; (b) in the case of purchases of STRYPES in connection with the original issuance thereof, (A) to allocate $37.045 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 $1.205 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 $37.045 and the making of an initial payment by the Holder with respect to the Forward Contract of $1.205; (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).

(b) By deleting Section 501 of the Principal Indenture in its entirety and inserting in its stead the following: "SECTION 501. Events of Default.

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, 16 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 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."

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.
