In consultation with your own financial and legal advisers, you should carefully consider, among other matters, the following discussion of risks before deciding whether an investment in the notes is suitable for you. The notes are not an appropriate investment for you if you are unsophisticated with respect to their significant components and interrelationships. Structure Risks of Notes Indexed to Interest Rate, Currency or Other Indices or Formulas If you invest in notes indexed to one or more interest rate, currency or other indices or formulas, there will be significant risks not associated with a conventional fixed rate or floating rate debt security. These risks include fluctuation of the indices or formulas and the possibility that you will receive a lower, or no, amount of principal, premium or interest and at different times than you expected. We have no control over a number of matters, including economic, financial and political events, that are important in determining the existence, magnitude and longevity of these risks and their results. In addition, if an index or formula used to determine any amounts payable in respect of the notes contains a multiplier or leverage factor, the effect of any change in that index or formula will be magnified. In recent years, values of certain indices and formulas have been volatile and volatility in those and other indices and formulas may be expected in the future. However, past experience is not necessarily indicative of what may occur in the future. Redemption May Adversely Affect Your Return on the Notes If your notes are redeemable at our option we may choose to redeem your notes at times when prevailing interest rates are relatively low. In addition, if your notes are subject to mandatory redemption, we may be required to redeem your notes at times when prevailing interest rates are also relatively low. As a result, you generally will not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as that of the notes. There May Not Be Any Trading Market for Your Notes; Many Factors Affect the Trading Market and Value of Your Notes We cannot assure you a trading market for your notes will ever develop or be maintained. In addition to our own creditworthiness, many other factors may affect the trading market value of, and trading market for, your notes. These factors include: . the complexity and volatility of the index or formula applicable to your notes, . the method of calculating the principal, premium and interest in respect of your notes, . the time remaining to the maturity of your notes, . the outstanding amount of your notes, . any redemption features of your notes, . the amount of other securities linked to the index or formula applicable to your notes, and . the level, direction and volatility of market interest rates generally. In addition, notes that are designed for specific investment objectives or strategies often experience a more limited trading market and more price volatility. There may be a limited number of buyers when you decide to sell your notes. This may affect the price you receive for your notes or your ability to sell your notes at all. You should not purchase notes unless you understand and know you can bear all of the investment risks related to your notes. S-3 Our Credit Ratings May Not Reflect All Risks of an Investment in the Notes Our credit ratings are an assessment of our ability to pay our obligations. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of your notes. Our credit ratings, however, may not reflect the potential impact of risks related to structure, market or other factors discussed above on the value of your notes. DESCRIPTION OF THE NOTES The notes will be issued as a series of debt securities under a senior indenture, dated as of October 1, 1993, as amended (the "1993 Indenture"), between ML&Co. and The Chase Manhattan Bank, as trustee. The term "senior debt securities," as used in this prospectus supplement, refers to all securities issued and issuable from time to time under ML&Co.'s senior indentures and includes the notes. The senior debt securities and ML&Co.'s senior indentures are more fully described in the accompanying prospectus. The following summary of the material provisions of the notes and of the 1993 Indenture is not complete and is qualified in its entirety by reference to the 1993 Indenture, a copy of which has been filed as an exhibit to the registration statement of which this prospectus supplement and the accompanying prospectus are a part. You should rely only on the information contained or incorporated by reference in this prospectus supplement, the accompanying prospectus and any pricing supplement. Neither we nor MLPF&S has authorized any other person to provide you with different or additional information. If anyone provides you with different or additional information, you should not rely on it. Neither we nor MLPF&S is making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information contained or incorporated by reference in this prospectus supplement, the accompanying prospectus and any pricing supplement is accurate only as of the date on the front cover of the applicable pricing supplement. The following description of notes will apply unless otherwise specified in an applicable pricing supplement. Terms of the Notes All senior debt securities, including the notes, issued and to be issued under ML&Co.'s senior indentures will be unsecured general obligations of ML&Co. and will rank equally with all other unsecured and unsubordinated indebtedness of ML&Co. from time to time outstanding. Because ML&Co. is a holding company, the right of ML&Co. and its creditors, including the holders of the notes, 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 that subsidiary, except to the extent that a bankruptcy court may recognize the claims of ML&Co. itself as a creditor of that subsidiary. In addition, dividends, loans and advances to ML&Co. from certain subsidiaries, including MLPF&S, are restricted by net capital requirements under the Securities Exchange Act of 1934, as amended, and under rules of certain exchanges and other regulatory bodies. ML&Co.'s senior indentures do not limit the aggregate principal amount of senior debt securities which ML&Co. may issue. ML&Co. may issue its senior debt securities from time to time as a single series or in two or more separate series up to the aggregate principal amount from time to time authorized by ML&Co. for each series. ML&Co. may, from time to time, without the consent of the holders of the notes, provide for the issuance of notes or other senior debt securities under its senior indentures in addition to the $17,939,515,000 aggregate principal amount of notes offered by this prospectus supplement. As of March 31, 2000, ML&Co. had approximately $19.9 billion aggregate principal amount of notes issued and outstanding. The aggregate principal amount of notes which may be offered and sold by this prospectus supplement may be reduced by the sale by ML&Co. of other securities under the registration statement of which this prospectus supplement and the accompanying prospectus are a part. S-4 The notes will be offered on a continuing basis and will mature on a day nine months or more from the date of their issue (the "stated maturity date"), as selected by the purchaser and agreed to by ML&Co., or on any date before the stated maturity date on which the principal or an installment of principal of a note becomes due and payable, whether by the declaration of acceleration, call for redemption at the option of ML&Co., notice of repayment at the option of the holder or otherwise (the stated maturity date or such prior date, as the case may be, is referred to as, a "Maturity"). Interest-bearing notes will bear interest at either fixed or floating rates as specified in the applicable pricing supplement. Some notes may not bear interest. In addition, notes may be issued at significant discounts from their principal amount payable at Maturity. Unless otherwise specified in the applicable pricing supplement, the notes will be denominated in United States dollars and ML&Co. will make payments of principal of, and premium, if any, and interest on, the notes in United States dollars. Interest rates offered by ML&CO. with respect to the notes may differ depending upon, among other factors, the aggregate principal amount of notes purchased in any single transaction. ML&Co. may offer notes with similar variable terms but different interest rates concurrently at any time. ML&Co. also may concurrently offer notes having different variable terms to different investors. Interest rates, interest rate formulae and other variable terms of the notes are subject to change by ML&Co. from time to time, but no change will affect any note already issued or as to which ML&Co. has accepted an offer to purchase. Each note will be issued in fully registered book-entry form or certificated form, in denominations of $1,000 and integral multiples of $1,000. Notes in book-entry form may be transferred or exchanged only through a participating member of The Depository Trust Company, also known as DTC, or any other depository as is identified in an applicable pricing supplement. See "-- Book-Entry Notes". Registration of transfer of notes in certificated form will be made at the corporate trust office of the trustee. There will be no service charge for any registration of transfer or exchange of notes, but ML&Co. may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with any transfer or exchange, other than exchanges pursuant to the 1993 Indenture not involving any transfer. ML&Co. will make payments of principal of, and premium and interest, if any, on notes in book-entry form through the trustee to the depository or its nominee. See "--Book-Entry Notes". Unless otherwise specified in the applicable pricing supplement, a beneficial owner of notes in book-entry form that are denominated in a currency other than United States dollars (a "Specified Currency") electing to receive payments of principal or any premium or interest in that Specified Currency must notify the participant of DTC through which its interest is held on or before the applicable regular record date, in the case of a payment of interest, and on or before the sixteenth day, whether or not a Business Day, as defined below, before its stated maturity date, in the case of principal or premium, of the beneficial owner's election to receive all or a portion of any payment in a Specified Currency. The participant must notify the depository of any election on or before the third Business Day after the regular record date. The depository will notify the paying agent of the election on or before the fifth Business Day after the regular record date. If complete instructions are received by the participant and forwarded to the depository, and forwarded by the depository to the paying agent, on or before the relevant dates, the beneficial owner of the notes in book-entry form will receive payments in the Specified Currency. In the case of notes in certificated form, ML&Co. will make payment of principal or premium, if any, due at Maturity of each note in immediately available funds upon presentation of the note and, in the case of any repayment on an optional repayment date, upon submission of a duly completed election form if and as required by the provisions described below, at the corporate trust office of the trustee in the Borough of Manhattan, The City of New York, or at any other place as ML&Co. may designate. Payment of interest due at Maturity of the notes in certificated form will be made to the person to whom payment of the principal thereof will be made. Payment of interest due on notes in certificated form other than at Maturity will be made at the corporate trust office of the trustee or, at the option of ML&Co., may be made by check mailed to the address S-5 of the person entitled to receive payment as the address shall appear in the security register. Notwithstanding the immediately preceding sentence, a holder of $1,000,000 or more in aggregate principal amount of notes in certificated form, whether having identical or different terms and provisions will, at the option of ML&Co., be entitled to receive interest payments, other than at Maturity, by wire transfer of immediately available funds if appropriate wire transfer instructions have been received in writing by the trustee not less than 15 days prior to the applicable interest payment date. Any wire instructions received by the trustee shall remain in effect until revoked by the applicable holder. "Business Day" means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which commercial banks are authorized or required by law, regulation or executive order to close in The City of New York; provided, however, that, with respect to non-United States dollar- denominated notes, the day is also not a day on which commercial banks are authorized or required by law, regulation or executive order to close in the Principal Financial Center, as defined below, of the country issuing the Specified Currency or, if the Specified Currency is Euro, the day is also a day on which the Trans-European Automated Real-time Gross Settlement Express Transfer (TARGET) System is open; provided, further, that, with respect to notes as to which LIBOR is an applicable Interest Rate Basis, the day is also a London Banking Day. "London Banking Day" means a day on which commercial banks are open for business, including dealings in the LIBOR Currency, as defined below, in London. "Principal Financial Center" means: (1) the capital city of the country issuing the Specified Currency, except that with respect to United States dollars, Australian dollars, Canadian dollars, Deutsche marks, Dutch guilders, Italian lire, South African rand and Swiss francs, the "Principal Financial Center" will be The City of New York, Sydney and Melbourne, Toronto, Frankfurt, Amsterdam, Milan, Johannesburg and Zurich, respectively, or (2) the capital city of the country to which the LIBOR Currency relates, except that with respect to United States dollars, Australian dollars, Canadian dollars, Deutsche marks, Dutch guilders, Italian lire, Portuguese escudos, South African rand and Swiss francs, the "Principal Financial Center" will be The City of New York, Sydney, Toronto, Frankfurt, Amsterdam, Milan, London, Johannesburg and Zurich, respectively. Redemption at the Option of ML&Co. The notes will not be subject to any sinking fund. ML&Co. may redeem the notes at its option before their stated maturity date only if an initial redemption date is specified in the applicable pricing supplement. If so indicated in the applicable pricing supplement, ML&Co. may redeem the notes at its option on any date on and after the applicable initial redemption date specified in the applicable pricing supplement. On and after the initial redemption date, if any, ML&Co. may redeem the related note at any time in whole or from time to time in part at its option at the applicable redemption price referred to below together with interest on the principal of the applicable note payable to the redemption date, on notice given, unless otherwise specified in the applicable pricing supplement, not more than 60 nor less than 30 days before the redemption date. ML&Co. will redeem the notes in increments of $1,000, provided that any remaining principal amount will be an authorized denomination of the applicable note. Unless otherwise specified in the applicable pricing supplement, the redemption price with respect to a note will initially mean a percentage, the initial redemption percentage, of the principal amount of the note to be redeemed specified in the applicable pricing supplement and shall decline at each anniversary of the initial redemption date by a percentage specified in the applicable pricing supplement, of the principal amount to be redeemed until the redemption price is 100% of the principal amount. Repayment at the Option of the Holder If so indicated in an applicable pricing supplement, ML&Co. will repay the notes in whole or in part at the option of the holders of the notes on any optional repayment date specified in the applicable pricing S-6 supplement. If no optional repayment date is indicated with respect to a note, it will not be repayable at the option of the holder before its stated maturity date. Any repayment in part will be in an amount equal to $1,000 or integral multiples of $1,000, provided that any remaining principal amount will be an authorized denomination of the applicable note. The repurchase price for any note so repurchased will be 100% of the principal amount to be repaid, together with interest on the principal of the applicable note payable to the date of repayment. For any note to be repaid, the trustee must receive, at its office maintained for such purpose in the Borough of Manhattan, The City of New York, currently the corporate trust office of the trustee, not more than 60 nor less than 30 days before the optional repayment date, the particular note being repaid: . in the case of a note in certificated form, the form entitled "Option to Elect Repayment" duly completed, or . in the case of a note in book-entry form, instructions to that effect from the applicable beneficial owner thereof to the depository and forwarded by the depository. Notices of elections from a holder to exercise the repayment option must be received by the trustee by 5:00 p.m., New York City time, on the last day for giving such notice. Exercise of the repayment option by the holder of a note will be irrevocable. Only the depository may exercise the repayment option in respect of global securities representing notes in book-entry form. Accordingly, beneficial owners of global securities that desire to have all or any portion of the notes in book-entry form represented by global securities repaid must instruct the participant through which they own their interest to direct the depository to exercise the repayment option on their behalf by forwarding the repayment instructions to the trustee as discussed above. In order to ensure that the instructions are received by the trustee on a particular day, the applicable beneficial owner must so instruct the participant through which it owns its interest before that participant's deadline for accepting instructions for that day. Different firms may have different deadlines for accepting instructions from their customers. Accordingly, beneficial owners of notes in book-entry form should consult the participants through which they own their interest for the respective deadlines. All instructions given to participants from beneficial owners of notes in book-entry form relating to the option to elect repayment will be irrevocable. In addition, at the time instructions are given, each beneficial owner will cause the participant through which it owns its interest to transfer its interest in the global security or securities representing the related notes in book-entry form, on the depository's records, to the trustee. See "--Book-Entry Notes". If applicable, ML&Co. will comply with the requirements of Section 14(e) of the Exchange Act and the rules promulgated thereunder and any other securities laws or regulations in connection with any repayment at the option of the holder. ML&Co. may at any time purchase notes at any price or prices in the open market or otherwise. Notes so purchased by ML&Co. may, at the discretion of ML&Co., be held, resold or surrendered to the trustee for cancellation. Interest Each interest-bearing note will bear interest from the date of issue at the rate per annum, in the case of a fixed rate note, or pursuant to the interest rate formula, in the case of a floating rate note, in each case as stated in the applicable pricing supplement until the principal of the note is paid or made available for payment. Interest will be payable in arrears on each interest payment date specified in the applicable pricing supplement on which an installment of interest is due and payable and at Maturity. The first payment of interest on any note originally issued between a regular record date and the related interest payment date will be made on the interest payment date immediately following the next succeeding regular record date to the holder on the next succeeding regular record date. The regular record date will be the fifteenth calendar day, whether or not a Business Day, immediately preceding the related interest payment date. S-7 Fixed Rate Notes Each fixed rate note will bear interest from, and including, the date of issue, at the rate per annum stated on the face of the note until the principal amount of the note is paid or made available for payment. Interest payments on fixed rate notes will equal the amount of interest accrued from and including the immediately preceding interest payment date in respect of which interest has been paid or from, and including, the date of issue, if no interest has been paid with respect to the applicable fixed rate notes, to, but excluding, the applicable interest payment date or Maturity, as the case may be. Unless otherwise specified in the applicable pricing supplement, interest on fixed rate notes will be computed on the basis of a 360-day year of twelve 30-day months. Interest on fixed rate notes will be payable semiannually on May 15 and November 15 of each year and at Maturity. If any interest payment date or the Maturity of a fixed rate note falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if made on the date the applicable payment was due, and no interest will accrue on the amount payable for the period from and after the interest payment date or Maturity, as the case may be. Floating Rate Notes Interest on floating rate notes will be determined by reference to the applicable Interest Rate Basis or Interest Rate Bases, which may be one or more of: . the CD Rate, . the CMT Rate, . the Commercial Paper Rate, . the Eleventh District Cost of Funds Rate, . the Federal Funds Rate, . LIBOR, . the Prime Rate, . the Treasury Rate, or . any other Interest Rate Basis or interest rate formula that is specified in the applicable pricing supplement. A floating rate note may bear interest with respect to two or more Interest Rate Bases. Each applicable pricing supplement will specify certain terms of the floating rate note being delivered, including: . whether the floating rate note is . a "Regular Floating Rate Note", . a "Inverse Floating Rate Note" or . a "Floating Rate/Fixed Rate Note", . the Interest Rate Basis or Bases, . the Initial Interest Rate, . the Interest Reset Dates, . the interest payment dates, S-8 . the period to maturity of the instrument or obligation with respect to which the Interest Rate Basis or Bases will be calculated (the "Index Maturity"), . the Maximum Interest Rate and Minimum Interest Rate, if any, . the number of basis points to be added to or subtracted from the related Interest Rate Basis or Bases (the "Spread"), . the percentage of the related Interest Rate Basis or Bases by which the Interest Rate Basis or Bases will be multiplied to determine the applicable interest rate (the "Spread Multiplier"), and . if one or more of the specified Interest Rate Bases is LIBOR, the LIBOR Currency, the Index Maturity and the Designated LIBOR Page. The interest rate borne by the floating rate notes will be determined as follows: Regular Floating Rate Notes. Unless a floating rate note is designated as a Floating Rate/Fixed Rate Note, an Inverse Floating Rate Note or as having an Addendum attached or as having "Other Provisions" apply relating to a different interest rate formula, it will be a "Regular Floating Rate Note" and will bear interest at the rate determined by reference to the applicable Interest Rate Basis or Bases: . plus or minus the applicable Spread, if any, and/or . multiplied by the applicable Spread Multiplier, if any. Commencing on the first Interest Reset Date, the rate at which interest on the Regular Floating Rate Note will be payable will be reset as of each Interest Reset Date; provided, however, that the interest rate in effect for the period from the date of issue to the first Interest Reset Date will be the Initial Interest Rate. Floating Rate/Fixed Rate Notes. If a floating rate note is designated as a "Floating Rate/Fixed Rate Note", it will bear interest at the rate determined by reference to the applicable Interest Rate Basis or Bases: . plus or minus the applicable Spread, if any, and/or . multiplied by the applicable Spread Multiplier, if any. Commencing on the first Interest Reset Date, the rate at which interest on the Floating Rate/Fixed Rate Note will be payable will be reset as of each Interest Reset Date; provided, however, that: . the interest rate in effect for the period from the date of issue to the first Interest Reset Date will be the Initial Interest Rate, and . the interest rate in effect commencing on, and including, the date on which interest begins to accrue on a fixed rate basis to Maturity will be the Fixed Interest Rate, if the rate is specified in the applicable pricing supplement, or if no Fixed Interest Rate is specified, the interest rate in effect on the Floating Rate/Fixed Rate Note on the day immediately preceding the date on which interest begins to accrue on a fixed rate basis. Inverse Floating Rate Notes. If a floating rate note is designated as an "Inverse Floating Rate Note" it will bear interest equal to the Fixed Interest Rate specified in the related pricing supplement minus the rate determined by reference to the applicable Interest Rate Basis or Bases: . plus or minus the applicable Spread, if any, and/or . multiplied by the applicable Spread Multiplier, if any; provided, however, that the interest rate on the applicable Inverse Floating Rate Note will not be less than zero percent. Commencing on the first Interest Reset Date, the rate at which interest on the Inverse Floating Rate S-9 Note is payable will be reset as of each Interest Reset Date; provided, however, that the interest rate in effect for the period from the date of issue to the first Interest Reset Date will be the Initial Interest Rate. The interest rate derived from an Interest Rate Basis will be determined in accordance with the applicable provisions below. The interest rate in effect on each day will be based on: . if the day is an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as defined below) immediately preceding the applicable Interest Reset Date, or . if the day is not an Interest Reset Date, the interest rate determined as of the Interest Determination Date immediately preceding the most recent Interest Reset Date. Interest Reset Dates. The applicable pricing supplement will specify the dates on which the interest rate on the related floating rate note will be reset (each, an "Interest Reset Date"). The Interest Reset Date will be, in the case of floating rate notes which reset: . daily--each Business Day; . weekly--the Wednesday of each week, with the exception of weekly reset Floating Rate Notes as to which the Treasury Rate is an applicable Interest Rate Basis, which will reset the Tuesday of each week, except as described below under "--Interest Determination Dates"; . monthly--the third Wednesday of each month, with the exception of monthly reset Floating Rate Notes as to which the Eleventh District Cost of Funds Rate is an applicable Interest Rate Basis, which will reset on the first calendar day of the month; . quarterly--the third Wednesday of March, June, September and December of each year; . semiannually--the third Wednesday of the two months specified in the applicable pricing supplement; and . annually--the third Wednesday of the month specified in the applicable pricing supplement; provided, however, that with respect to Floating Rate/Fixed Rate Notes, the rate of interest will not reset after the applicable date on which interest on a fixed rate basis begins to accrue. If any Interest Reset Date for any floating rate note would otherwise be a day that is not a Business Day, the applicable Interest Reset Date will be postponed to the next succeeding day that is a Business Day, except that in the case of a floating rate note as to which LIBOR is an applicable Interest Rate Basis, if the Business Day falls in the next succeeding calendar month, then the applicable Interest Reset Date will be the immediately preceding Business Day. In addition, in the case of a floating rate note for which the Treasury Rate is an applicable Interest Rate Basis if the Interest Determination Date would otherwise fall on an Interest Reset Date, then the applicable Interest Reset Date will be postponed to the next succeeding Business Day. Maximum and Minimum Interest Rates. A floating rate note may also have either or both of the following: . a maximum numerical limitation, or ceiling, on the rate at which interest may accrue during any interest period (a "Maximum Interest Rate"), and . a minimum numerical limitation, or floor, on the rate at which interest may accrue during any period (a "Minimum Interest Rate"). The 1993 Indenture is, and any notes issued under the 1993 Indenture will be, governed by and construed in accordance with the laws of the State of New York. Under present New York law, the maximum rate of interest is 25% per annum on a simple interest basis. This limit may not apply to securities in which $2,500,000 or more has been invested. While ML&Co. believes that New York law would be given effect by a S-10 state or federal court sitting outside of New York, state laws frequently regulate the amount of interest that may be charged to and paid by a borrower, including, in some cases, corporate borrowers. It is suggested that prospective investors consult their personal advisors with respect to the applicability of these laws. ML&Co. has agreed for the benefit of the beneficial owners of the notes, to the extent permitted by law, not to claim voluntarily the benefits of any laws concerning usurious rates of interest against a beneficial owner of the notes. Interest Payments. Each applicable pricing supplement will specify the dates on which interest will be payable. Each floating rate note will bear interest from the date of issue at the rates specified in the applicable floating rate note until the principal of the applicable note is paid or otherwise made available for payment. The interest payment dates with respect to floating rate notes will be, in the case of floating rate notes which reset: . daily, weekly or monthly--the third Wednesday of each month or on the third Wednesday of March, June, September and December of each year, as specified in the applicable pricing supplement; . quarterly--the third Wednesday of March, June, September and December of each year; . semiannually--the third Wednesday of the two months of each year specified in the applicable pricing supplement; . annually--the third Wednesday of the month of each year specified in the applicable pricing supplement; and . at Maturity. If any interest payment date for any floating rate note, other than an interest payment date at Maturity, would otherwise be a day that is not a Business Day, the interest payment date will be postponed to the next succeeding day that is a Business Day except that in the case of a floating rate note as to which LIBOR is an applicable Interest Rate Basis, if the Business Day falls in the next succeeding calendar month, the applicable interest payment date will be the immediately preceding Business Day. If the Maturity of a floating rate note falls on a day that is not a Business Day, the payment of principal, premium, if any, and interest will be made on the next succeeding Business Day, and no interest on such payment will accrue for the period from and after the Maturity. All percentages resulting from any calculation on floating rate notes will be rounded to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards. For example, 9.876545%, or .09876545, would be rounded to 9.87655%, or .0987655. All dollar amounts used in or resulting from any calculation on floating rate notes will be rounded to the nearest cent with one-half cent being rounded upward. Interest payments on floating rate notes will equal the amount of interest accrued from and including the immediately preceding interest payment date in respect of which interest has been paid or from and including the date of issue, if no interest has been paid, to but excluding the related interest payment date or Maturity. With respect to each floating rate note, accrued interest is calculated by multiplying its principal amount by an accrued interest factor. The accrued interest factor is computed by adding the interest factor calculated for each day in the period for which accrued interest is being calculated. . In the case of notes for which the Interest Rate Basis is the CD Rate, the Commercial Paper Rate, the Eleventh District Cost of Funds Rate, the Federal Funds Rate, LIBOR or the Prime Rate, the interest factor for each day will be computed by dividing the interest rate applicable to each day by 360. S-11 . In the case of notes for which the Interest Rate Basis is the CMT Rate or the Treasury Rate, the interest factor for each day will be computed by dividing the interest rate applicable to each day by the actual number of days in the year. . The interest factor for notes for which the interest rate is calculated with reference to two or more Interest Rate Bases will be calculated in each period in the same manner as if only one of the applicable Interest Rate Bases applied. Interest Determination Dates. The interest rate applicable to each interest reset period commencing on the Interest Reset Date with respect to that interest reset period will be the rate determined as of the applicable "Interest Determination Date". . The Interest Determination Date with respect to the Federal Funds Rate and the Prime Rate will be the Business Day immediately preceding the related Interest Reset Date. .

Book-Entry Notes Description of the Global Securities Upon issuance, all notes in book-entry form having the same date of issue, Maturity and otherwise having identical terms and provisions will be represented by one or more fully registered global notes (the "Global Notes"). Each Global Note will be deposited with, or on behalf of, The Depository Trust Company as depository registered in the name of the depository or a nominee of the depository. Unless and until it is exchanged in whole or in part for notes in certificated form, no Global Note may be transferred except as a whole by the depository to a nominee of the depository or by a nominee of the depository to the depository or another nominee of the depository or by the depository or any such nominee to a successor of the depository or a nominee of the successor. DTC Procedures The following is based on information furnished by the depository: The depository will act as securities depository for the notes in book- entry form. The notes in book-entry form will be issued as fully registered securities registered in the name of Cede & Co., the depository's partnership nominee. One fully registered Global Note will be issued for each issue of notes in book-entry form, each in the aggregate principal amount of the issue, and will be deposited with the depository. If, however, the aggregate principal amount of any issue exceeds $400,000,000, one Global Note will be issued with respect to each $400,000,000 of principal amount and an additional Global Note will be issued with respect to any remaining principal amount of the issue. The depository is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, 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 Exchange Act. The depository holds securities that its participants deposit with the depository. The depository also facilitates the settlement among participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants' accounts, thereby eliminating the need for physical movement of securities certificates. Direct participants of the depository include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. The depository is owned by a number of its direct 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 depository's system is also available S-21 to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to the depository and its participants are on file with the SEC. Purchasers of notes in book-entry form under the depository's system must be made by or through direct participants, which will receive a credit for those notes in book-entry form on the depository's records. The ownership interest of each actual purchaser of each note in book-entry form represented by a Global Note is, in turn, to be recorded on the records of direct participants and indirect participants. Beneficial owners in book-entry form will not receive written confirmation from the depository of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct participants or indirect participants through which the beneficial owner entered into the transaction. Transfers of ownership interests in a Global Note representing notes in book-entry form are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners of a Global Note representing notes in book-entry form will not receive notes in certificated form representing their ownership interests therein, except in the event that use of the book-entry system for such notes in book-entry form is discontinued. To facilitate subsequent transfers, all Global Notes representing notes in book-entry form which are deposited with, or on behalf of, the depository are registered in the name of the depository's nominee, Cede & Co. The deposit of Global Notes with, or on behalf of, the depository and their registration in the name of Cede & Co. effect no change in beneficial ownership. The depository has no knowledge of the actual beneficial owners of the Global Notes representing the notes in book-entry form; the depository's records reflect only the identity of the direct participants to whose accounts such notes in book-entry form are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers. Conveyance of notices and other communications by the depository to direct participants, by direct participants to indirect participants, and by direct 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. Neither the depository nor Cede & Co. will consent or vote with respect to the Global Notes representing the notes in book-entry form. Under its usual procedures, the depository mails an omnibus proxy to ML&Co. as soon as possible after the applicable record date. The omnibus proxy assigns Cede & Co.'s consenting or voting rights to those direct participants, identified in a listing attached to the omnibus proxy, to whose accounts the notes in book- entry form are credited on the applicable record date. ML&Co. will make principal, premium, if any, and/or interest, if any, payments on the Global Notes representing the notes in book-entry form in immediately available funds to the depository. The depository's practice is to credit direct participants' accounts on the applicable payment date in accordance with their respective holdings shown on the depository's records unless the depository has reason to believe that it will not receive payment on the applicable payment date. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name", and will be the responsibility of the applicable participant and not of the depository, the trustee or ML&Co., subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, premium, if any, and/or interest, if any, to the depository is the responsibility of ML&Co. and the trustee, disbursement of payments to direct participants will be the responsibility of the depository, and disbursement of payments to the beneficial owners will be the responsibility of direct participants and indirect participants. S-22 If applicable, redemption notices shall be sent to Cede & Co. If less than all of the notes in book-entry form of like tenor and terms are being redeemed, the depository's practice is to determine by lot the amount of the interest of each direct participant in the issue to be redeemed. A beneficial owner will give notice of any option to elect to have its notes in book-entry form repaid by ML&Co., through its participant, to the trustee, and will effect delivery of the applicable notes in book-entry form by causing the direct participant to transfer the participant's interest in the Global Note notes in book-entry form, on the depository's records, to the trustee. The depository may discontinue providing its services as securities depository with respect to the notes in book-entry form at any time by giving reasonable notice to ML&Co. or the trustee. In the event that a successor securities depository is not obtained, notes in certificated form are required to be printed and delivered. ML&Co. may decide to discontinue use of the system of book-entry transfers through the depository or a successor securities depository. In that event, notes in certificated form will be printed and delivered. The laws of some states may require that certain purchasers of securities take physical delivery of 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 depository, or its nominee, is the registered owner of a Global Note, the depository or its nominee, as the case may be, will be considered the sole owner or holder of the notes represented by such Global Note for all purposes under the 1993 Indenture. Except as provided below, beneficial owners of a Global Note will not be entitled to have the notes represented by a Global Note registered in their names, will not receive or be entitled to receive physical delivery of the notes in definitive form and will not be considered the owners or holders thereof under the 1993 Indenture. Accordingly, each person owning a beneficial interest in a Global Note must rely on the procedures of the depository and, if that person is not a participant, on the procedures of the participant through which that person owns its interest, to exercise any rights of a holder under the 1993 Indenture. ML&Co. understands that under existing industry practices, in the event that ML&Co. requests any action of holders or that an owner of a beneficial interest in a Global Note desires to give or take any action which a holder is entitled to give or take under the 1993 Indenture, the depository would authorize the participants holding the relevant beneficial interests to give or take the desired action, and the participants would authorize beneficial owners owning through the participants to give or take the desired action or would otherwise act upon the instructions of beneficial owners. Exchange for Notes in Certificated Form If: (a) the depository is at any time unwilling or unable to continue as depository and a successor depository is not appointed by ML&Co. within 60 days, (b) ML&Co. executes and delivers to the trustee a company order to the effect that the Global Notes shall be exchangeable, or (c) an Event of Default has occurred and is continuing with respect to the notes, the Global Note or Global Notes will be exchangeable for notes in certificated form of like tenor and of an equal aggregate principal amount, in denominations of $1,000 and integral multiples of $1,000. The certificated notes will be registered in the name or names as the depository instructs the trustee. It is expected that instructions may be based upon directions received by the depository from participants with respect to ownership of beneficial interests in Global Notes. S-23 The information in this section concerning the depository and the depository's system has been obtained from sources that ML&Co. believes to be reliable, but ML&Co. takes no responsibility for the accuracy of the information. UNITED STATES FEDERAL INCOME TAXATION The following summary of certain United States Federal income tax consequences of the purchase, ownership and disposition of the notes is based upon laws, regulations, rulings and decisions now in effect, all of which are subject to change, including changes in effective dates, or possible differing interpretations. It deals only with notes 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, persons holding notes as a hedge against currency risks or as a position in a "straddle" for tax purposes, or persons whose functional currency is not the United States dollar. It also does not deal with holders other than original purchasers, except where otherwise specifically noted. Persons considering the purchase of the notes should consult their own tax advisors concerning the application of United States Federal income tax laws to their particular situations as well as any consequences of the purchase, ownership and disposition of the notes arising under the laws of any other taxing jurisdiction. As used in this prospectus, the term "U.S. Holder" means a beneficial owner of a note that is for United States Federal income tax purposes: (1) a citizen or resident of the United States, (2) a corporation or a partnership (including an entity treated as a corporation or a partnership for United States Federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia (unless, in the case of a partnership, Treasury regulations are adopted that provide otherwise), (3) an estate whose income is subject to United States Federal income tax regardless of its source, (4) a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust, or (5) any other person whose income or gain in respect of a note is effectively connected with the conduct of a United States trade or business. Certain trusts not described in clause (4) above in existence on August 20, 1996 that elect to be treated as a United States person will also be a U.S. Holder for purposes of the following discussion. As used herein, the term "non- U.S. Holder" means a beneficial owner of a note that is not a U.S. Holder. U.S. Holders Payments of Interest. Payments of interest on a note 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 method of tax accounting). Original Issue Discount. The following summary is a general discussion of the United States Federal income tax consequences to U.S. Holders of the purchase, ownership and disposition of notes issued with original issue discount ("Discount Notes"). The following summary is based upon final Treasury regulations (the "OID Regulations") released by the Internal Revenue Service on January 27, 1994, as amended on June 11, 1996, under the original issue discount provisions of the Code. S-24 For United States Federal income tax purposes, original issue discount is the excess of the stated redemption price at maturity of a note over its issue price, if such excess equals or exceeds a de minimis amount (generally 1/4 of 1% of the note's stated redemption price at maturity multiplied by the number of complete years to its maturity from its issue date or, in the case of a note providing for the payment of any amount other than qualified stated interest (as defined below) prior to maturity, multiplied by the weighted average maturity of the note). The issue price of each note of an issue of notes equals the first price at which a substantial amount of the notes has been sold (ignoring sales to bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents, or wholesalers). The stated redemption price at maturity of a note is the sum of all payments provided by the note other than "qualified stated interest" payments. The term "qualified stated interest" generally means stated interest that is unconditionally payable in cash or property (other than debt instruments of the issuer) at least annually at a single fixed rate. In addition, under the OID Regulations, if a note bears interest for one or more accrual periods at a rate below the rate applicable for the remaining term of the note (e.g., notes with teaser rates or interest holidays), and if the greater of either the resulting foregone interest on the note or any "true" discount on the note (i.e., the excess of the note's stated principal amount over its issue price) equals or exceeds a specified de minimis amount, then the stated interest on the note would be treated as original issue discount rather than qualified stated interest. Payments of qualified stated interest on a note are 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 method of tax accounting). A U.S. Holder of a Discount Note must include original issue discount in income as ordinary interest for United States Federal income tax purposes as it accrues under a constant yield method in advance of receipt of the cash payments attributable to such income, regardless of the U.S. Holder's regular method of tax accounting. In general, the amount of original issue discount included in income by the initial U.S. Holder of a Discount Note is the sum of the daily portions of original issue discount with respect to the Discount Note for each day during the taxable year (or portion of the taxable year) on which the U.S. Holder held the Discount Note. The "daily portion" of original issue discount on any Discount Note is determined by allocating to each day in any accrual period a ratable portion of the original issue discount allocable to that accrual period. An "accrual period" may be of any length and the accrual periods may vary in length over the term of the Discount Note, provided that each accrual period is no longer than one year and each scheduled payment of principal or interest occurs either on the final day of an accrual period or on the first day of an accrual period. The amount of original issue discount allocable to each accrual period is generally equal to the difference between . the product of the Discount Note's adjusted issue price at the beginning of such accrual period and its yield to maturity (determined on the basis of compounding at the close of each accrual period and appropriately adjusted to take into account the length of the particular accrual period) and . the amount of any qualified stated interest payments allocable to such accrual period. The "adjusted issue price" of a Discount Note at the beginning of any accrual period is the sum of the issue price of the Discount Note plus the amount of original issue discount allocable to all prior accrual periods minus the amount of any prior payments on the Discount Note that were not qualified stated interest payments. Under these rules, U.S. Holders generally will have to include in income increasingly greater amounts of original issue discount in successive accrual periods. A U.S. Holder who purchases a Discount Note for an amount that is greater than its adjusted issue price as of the purchase date and less than or equal to the sum of all amounts payable on the Discount Note after the purchase date other than payments of qualified stated interest, will be considered to have purchased the Discount Note at an "acquisition premium". Under the acquisition premium rules, the amount of original issue discount which such U.S. Holder must include in its gross income with respect to such Discount Note for any taxable year (or portion thereof in which the U.S. Holder holds the Discount Note) will be reduced (but not below zero) by the portion of the acquisition premium properly allocable to the period. S-25 Under the OID Regulations, Floating Rate Notes and Indexed Notes (hereinafter "Variable Notes") are subject to special rules whereby a Variable Note will qualify as a "variable rate debt instrument" if . its issue price does not exceed the total noncontingent principal payments due under the Variable Note by more than a specified de minimis amount and . it provides for stated interest, paid or compounded at least annually, at current values of: . one or more qualified floating rates, . a single fixed rate and one or more qualified floating rates, . a single objective rate, or . a single fixed rate and a single objective rate that is a qualified inverse floating rate. A "qualified floating rate" is any variable rate where variations in the value of such rate can reasonably be expected to measure contemporaneous variations in the cost of newly borrowed funds in the currency in which the Variable Note is denominated. Although a multiple of a qualified floating rate will generally not itself constitute a qualified floating rate, a variable rate equal to the product of a qualified floating rate and a fixed multiple that is greater than .65 but not more than 1.35 will constitute a qualified floating rate. A variable rate equal to the product of a qualified floating rate and a fixed multiple that is greater than .65 but not more than 1.35, increased or decreased by a fixed rate, will also constitute a qualified floating rate. In addition, under the OID Regulations, two or more qualified floating rates that can reasonably be expected to have approximately the same values throughout the term of the Variable Note (e.g., two or more qualified floating rates with values within 25 basis points of each other as determined on the Variable Note's issue date) will be treated as a single qualified floating rate. Notwithstanding the foregoing, a variable rate that would otherwise constitute a qualified floating rate but which is subject to one or more restrictions such as a maximum numerical limitation (i.e., a cap) or a minimum numerical limitation (i.e., a floor) may, under certain circumstances, fail to be treated as a qualified floating rate under the OID Regulations unless such cap or floor is fixed throughout the term of the note. An "objective rate" is a rate that is not itself a qualified floating rate but which is determined using a single fixed formula that is based on objective financial or economic information. A rate will not qualify as an objective rate if it is based on information that is within the control of the issuer (or a related party) or that is unique to the circumstances of the issuer (or a related party), such as dividends, profits, or the value of the issuer's stock (although a rate does not fail to be an objective rate merely because it is based on the credit quality of the issuer). A "qualified inverse floating rate" is any objective rate where such rate is equal to a fixed rate minus a qualified floating rate, as long as variations in the rate can reasonably be expected to inversely reflect contemporaneous variations in the qualified floating rate. The OID Regulations also provide that if a Variable Note provides for stated interest at a fixed rate for an initial period of one year or less followed by a variable rate that is either a qualified floating rate or an objective rate and if the variable rate on the Variable Note's issue date is intended to approximate the fixed rate (e.g., the value of the variable rate on the issue date does not differ from the value of the fixed rate by more than 25 basis points), then the fixed rate and the variable rate together will constitute either a single qualified floating rate or objective rate, as the case may be. If a Variable Note that provides for stated interest at either a single qualified floating rate or a single objective rate throughout the term thereof qualifies as a "variable rate debt instrument" under the OID Regulations, and if the interest on a Variable Note is unconditionally payable in cash or property (other than debt instruments of the issuer) at least annually, then all stated interest on the Variable Note will constitute qualified stated interest and will be taxed accordingly. Thus, a Variable Note that provides for stated interest at either a single qualified floating rate or a single objective rate throughout the term thereof and that qualifies as a "variable rate debt instrument" under the OID Regulations will generally not be treated as having been issued with original issue discount unless the Variable Note is issued at a "true" discount (i.e., at a price below the Variable Note's stated principal amount) in excess of a specified de minimis amount. The amount of qualified stated interest and the amount of original issue discount, if any, that accrues during an accrual period on such a S-26 Variable Note is determined under the rules applicable to fixed rate debt instruments by assuming that the variable rate is a fixed rate equal to (1) in the case of a qualified floating rate or qualified inverse floating rate, the value as of the issue date, of the qualified floating rate or qualified inverse floating rate, or (2) in the case of an objective rate (other than a qualified inverse floating rate), a fixed rate that reflects the yield that is reasonably expected for the Variable Note. The qualified stated interest allocable to an accrual period is increased (or decreased) if the interest actually paid during an accrual period exceeds (or is less than) the interest assumed to be paid during the accrual period pursuant to the foregoing rules. In general, any other Variable Note that qualifies as a "variable rate debt instrument" will be converted into an "equivalent" fixed rate debt instrument for purposes of determining the amount and accrual of original issue discount and qualified stated interest on the Variable Note. The OID Regulations generally require that such a Variable Note be converted into an "equivalent" fixed rate debt instrument by substituting any qualified floating rate or qualified inverse floating rate provided for under the terms of the Variable Note with a fixed rate equal to the value of the qualified floating rate or qualified inverse floating rate, as the case may be, as of the Variable Note's issue date. Any objective rate (other than a qualified inverse floating rate) provided for under the terms of the Variable Note is converted into a fixed rate that reflects the yield that is reasonably expected for the Variable Note. In the case of a Variable Note that qualifies as a "variable rate debt instrument" and provides for stated interest at a fixed rate in addition to either one or more qualified floating rates or a qualified inverse floating rate, the fixed rate is initially converted into a qualified floating rate (or a qualified inverse floating rate, if the Variable Note provides for a qualified inverse floating rate). Under such circumstances, the qualified floating rate or qualified inverse floating rate that replaces the fixed rate must be such that the fair market value of the Variable Note as of the Variable Note's issue date is approximately the same as the fair market value of an otherwise identical debt instrument that provides for either the qualified floating rate or qualified inverse floating rate rather than the fixed rate. Subsequent to converting the fixed rate into either a qualified floating rate or a qualified inverse floating rate, the Variable Note is then converted into an "equivalent" fixed rate debt instrument in the manner described above. Once the Variable Note is converted into an "equivalent" fixed rate debt instrument pursuant to the foregoing rules, the amount of original issue discount and qualified stated interest, if any, are determined for the "equivalent" fixed rate debt instrument by applying the general original issue discount rules to the "equivalent" fixed rate debt instrument and a U.S. Holder of the Variable Note will account for such original issue discount and qualified stated interest as if the U.S. Holder held the "equivalent" fixed rate debt instrument. Each accrual period appropriate adjustments will be made to the amount of qualified stated interest or original issue discount assumed to have been accrued or paid with respect to the "equivalent" fixed rate debt instrument in the event that such amounts differ from the actual amount of interest accrued or paid on the Variable Note during the accrual period. If a Variable Note does not qualify as a "variable rate debt instrument" under the OID Regulations, then the Variable Note would be treated as a contingent payment debt obligation. On June 11, 1996, the Treasury Department issued final regulations (the "CPDI Regulations") concerning the proper United States Federal income tax treatment of contingent payment debt instruments. In general, the CPDI 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. Specifically, the CPDI Regulations generally require a U.S. Holder of such an instrument to include future contingent and noncontingent interest payments in income as such interest accrues based upon a projected payment schedule. Moreover, in general, under the CPDI Regulations, any gain recognized by a U.S. Holder on the sale, exchange, or retirement of a contingent payment debt instrument will be treated as ordinary income and all or a S-27 portion of any loss realized could be treated as ordinary loss as opposed to capital loss (depending upon the circumstances). The CPDI Regulations apply to debt instruments issued on or after August 13, 1996. The proper United States Federal income tax treatment of Variable Notes that are treated as contingent payment debt obligations will be more fully described in the applicable pricing supplement. Furthermore, any other special United States Federal income tax considerations, not otherwise discussed herein, which are applicable to any particular issue of notes will be discussed in the applicable pricing supplement. ML&Co. may issue notes which; . may be redeemable at the option of ML&Co. prior to their stated maturity (a "call option") and/or . may be repayable at the option of the holder prior to their stated maturity (a "put option"). Notes containing such features may be subject to rules that differ from the general rules discussed above. Investors intending to purchase notes with such features should consult their own tax advisors, since the original issue discount consequences will depend, in part, on the particular terms and features of the purchased notes. U.S. Holders may generally, upon election, include in income all interest (including stated interest, acquisition discount, original issue discount, de minimis original issue discount, market discount, de minimis market discount, and unstated interest, as adjusted by any amortizable bond premium or acquisition premium) that accrues on a debt instrument by using the constant yield method applicable to original issue discount, subject to certain limitations and exceptions. Foreign-Currency Notes. The United States Federal income tax consequences of the purchase, ownership and disposition of notes providing for payments denominated in a currency other than U.S. dollars will be more fully described in the applicable pricing supplement. Short-Term Notes. Notes that have a fixed maturity of one year or less ("Short-Term Notes") will be treated as having been issued with original issue discount. In general, an individual or other cash method U.S. Holder is not required to accrue such original issue discount unless the U.S. Holder elects to do so. If such an election is not made, any gain recognized by the U.S. Holder on the sale, exchange or maturity of the Short-Term Note will be ordinary income to the extent of the original issue discount accrued on a straight-line basis, or upon election under the constant yield method (based on daily compounding), through the date of sale or maturity, and a portion of the deductions otherwise allowable to the U.S. Holder for interest on borrowings allocable to the Short-Term Note will be deferred until a corresponding amount of income is realized. U.S. Holders who report income for United States Federal income tax purposes under the accrual method, and certain other holders including banks and dealers in securities, are required to accrue original issue discount on a Short-Term Note on a straight-line basis unless an election is made to accrue the original issue discount under a constant yield method (based on daily compounding). Market Discount. If a U.S. Holder purchases a note, other than a Discount Note, for an amount that is less than its issue price (or, in the case of a subsequent purchaser, its stated redemption price at maturity) or, in the case of a Discount Note, for an amount that is less than its adjusted issue price as of the purchase date, such U.S. Holder will be treated as having purchased the note at a "market discount", unless such market discount is less than a specified de minimis amount. Under the market discount rules, a U.S. Holder will be required to treat any partial principal payment (or, in the case of a Discount Note, any payment that does not constitute qualified stated interest) on, or any gain realized on the sale, exchange, retirement or other disposition of, a note as ordinary income to the extent of the lesser of: . the amount of such payment or realized gain or S-28 . the market discount which has not previously been included in income and is treated as having accrued on the note 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 date of the note, 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 note with market discount until the maturity of the Note or certain earlier dispositions, because a current deduction is only allowed to the extent the interest expense exceeds an allocable portion of 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 treatment as ordinary income of gain upon the disposition of the note and upon the receipt of certain cash payments and regarding the deferral of interest deductions will not apply. Generally, such currently included market discount is treated as ordinary interest for United States Federal income tax purposes. Such an election will apply to all debt instruments acquired by the U.S. Holder on or after the first day of the taxable year to which such election applies and may be revoked only with the consent of the IRS. Premium. If a U.S. Holder purchases a note for an amount that is greater than the sum of all amounts payable on the note after the purchase date other than payments of qualified stated interest, the U.S. Holder will be considered to have purchased the note with "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 note and may offset interest otherwise required to be included in respect of the note during any taxable year by the amortized amount of such excess for the taxable year. However, if the note may be optionally redeemed after the U.S. Holder acquires it at a price in excess of its stated redemption price at maturity, special rules would apply which could result in a deferral of the amortization of some bond premium until later in the term of the note. Any election to amortize bond premium applies to all taxable debt obligations then owned and thereafter acquired by the U.S. Holder and may be revoked only with the consent of the IRS. Disposition of a Note. Except as discussed above, upon the sale, exchange or retirement of a note, a U.S. Holder generally will recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange or retirement (other than amounts representing accrued and unpaid interest) and the U.S. Holder's adjusted tax basis in the note. A U.S. Holder's adjusted tax basis in a note generally will equal the U.S. Holder's initial investment in the note increased by any original issue discount included in income (and accrued market discount, if any, if the U.S. Holder has included such market discount in income) and decreased by the amount of any payments, other than qualified stated interest payments, received and amortizable bond premium taken with respect to the note. Such gain or loss generally will be long-term capital gain or loss if the note were held for more than one year. Long-term capital gains of individuals are subject to reduced capital gain rates while short-term capital gains are subject to ordinary income rates. The deductibility of capital losses is subject to certain limitations. Prospective investors should consult their own tax advisors concerning these tax law provisions. Non-U.S. Holders A non-U.S. Holder will not be subject to United States Federal income taxes on payments of principal, premium (if any) or interest (including original issue discount, if any) on a note, unless such non-U.S. Holder is a direct or indirect 10% or greater shareholder of ML&Co., a controlled foreign corporation related to ML&Co. or a bank receiving interest described in section 881(c)(3)(A) of the Code. To qualify for the exemption from taxation, the last United States payor in the chain of payment prior to payment to a non-U.S. Holder (the "Withholding Agent") must have received in the year in which a payment of interest or principal occurs, or in either of the two preceding calendar years, a statement that (1) is signed by the beneficial owner of the note S-29 under penalties of perjury, (2) certifies that such owner is not a U.S. Holder and (3) provides the name and address of the beneficial owner. The statement may be made on an IRS Form W-8, IRS Form W-8 BEN or a substantially similar form, and the beneficial owner must inform the Withholding Agent of any change in the information on the statement within 30 days of such change. If a note is held through a securities clearing organization or certain other financial institutions, the organization or institution may provide a signed statement to the Withholding Agent. However, in such case, the signed statement must be accompanied by a copy of the IRS Form W-8, IRS Form W-8 BEN or the substitute form provided by the beneficial owner to the organization or institution. The Treasury Department is considering implementation of further certification requirements aimed at determining whether the issuer of a debt obligation is related to holders thereof. To claim an exemption from United States withholding for interest or proceeds from sale paid after December 31, 2000, a non-U.S. Holder may no longer use the IRS Form W-8 to certify its status as a non-U.S. Holder. On October 6, 1997, the Treasury issued new regulations (the "New Regulations") which make certain modifications to the withholding, backup withholding and information reporting rules. The New Regulations attempt to unify certification requirements and modify reliance standards. The New Regulations will generally be effective for payments made after December 31, 2000, subject to certain transition rules. Prospective investors are urged to consult their own tax advisors regarding the New Regulations. After December 31, 2000, interest accrued under the OID Regulations will not be subject to withholding upon sale or exchange (other than a redemption) of a note unless the Withholding Agent knows or has reason to know that such instrument was sold with the principal purpose of avoiding tax. Generally, a non-U.S. Holder will not be subject to United States Federal income taxes on any amount which constitutes capital gain upon retirement or disposition of a note, provided the gain is not effectively connected with the conduct of a trade or business in the United States by the non-U.S. Holder. Certain other exceptions may be applicable, and a non-U.S. Holder should consult its tax advisor in this regard. The notes will not be includible in the estate of a non-U.S. Holder unless the individual is a direct or indirect 10% or greater shareholder of ML&Co. or, at the time of such individual's death, payments in respect of the notes would have been effectively connected with the conduct by such individual of a trade or business in the United States. Backup Withholding Backup withholding of United States Federal income tax at a rate of 31% may apply to payments made in respect of the notes to registered owners who are not "exempt recipients" and who fail to provide certain identifying information, such as the registered owner's taxpayer identification number, in the required manner. Generally, individuals are not exempt recipients, whereas corporations and certain other entities generally are exempt recipients. Payments made in respect of the notes to a U.S. Holder must be reported to the IRS, unless the U.S. Holder is an exempt recipient or establishes an exemption. Compliance with the identification procedures described in the preceding section would establish an exemption from backup withholding for those non-U.S. Holders who are not exempt recipients. In addition, upon the sale of a note to (or through) a broker, the broker must withhold 31% of the entire purchase price, unless either: . the broker determines that the seller is a corporation or other exempt recipient or . the seller provides, in the required manner, certain identifying information and, in the case of a non-U.S. Holder, certifies that such seller is a non-U.S. Holder (and certain other conditions are met). S-30 Such a sale must also be reported by the broker to the IRS, unless either: . the broker determines that the seller is an exempt recipient or . the seller certifies its non-U.S. status (and certain other conditions are met). After December 31, 2000, interest accrued under the OID Regulations will not be subject to withholding upon sale or exchange (other than a redemption) of a note unless the Withholding Agent knows or has reason to know that such instrument was sold with the principal purpose of avoiding tax. Certification of the registered owner's non-U.S. status would be made normally on an IRS Form W-8, IRS Form W-8 BEN under penalties of perjury, although in certain cases it may be possible to submit other documentary evidence. After December 31, 2000, a registered owner may no longer use an IRS Form W-8 to certify to its non-U.S. status. In addition, prospective U.S. Holders are strongly urged to consult their own tax advisors with respect to the New Withholding Regulations. See " United States Federal Income Taxation--Non-U.S. Holders". 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. PLAN OF DISTRIBUTION ML&Co. is offering the notes for sale on a continuing basis through the agent, MLPF&S, who will purchase the notes, as principal, from ML&Co., for resale to investors and other purchasers at varying prices relating to prevailing market prices at the time of resale as determined by the agent, or, if so specified in an applicable pricing supplement, for resale at a fixed public offering price. Unless otherwise specified in an applicable pricing supplement, any note sold to the agent as principal will be purchased by the agent at a price equal to 100% of the principal amount of the note less a percentage of the principal amount equal to the commission applicable to an agency sale as described below of a note of identical maturity. If agreed to by ML&Co. and the agent, the agent may utilize its reasonable efforts on an agency basis to solicit offers to purchase the notes at 100% of the principal amount of the notes, unless otherwise specified in an applicable pricing supplement. ML&Co. will pay a commission to the agent, ranging from .050% to .600% of the principal amount of a note, depending upon its stated maturity or, with respect to a note for which the stated maturity is in excess of 30 years, a commission as agreed upon by ML&Co. and the agent at the time of sale, sold through the agent. The agent may sell notes it has purchased from ML&Co. as principal to other dealers for resale to investors, and may allow any portion of the discount received in connection with such purchases from ML&Co. to such dealers. After the initial public offering of notes, the public offering price, in the case of notes to be resold at a fixed public offering price, the concession and the discount allowed to dealers may be changed. ML&Co. reserves the right to withdraw, cancel or modify the offer made by this prospectus supplement without notice and may reject orders, in whole or in part, whether placed directly with ML&Co. or through the agent. The agent will have the right, in its discretion reasonably exercised, to reject in whole or in part any offer to purchase notes received by the agent. Unless otherwise specified in an applicable pricing supplement, payment of the purchase price of the notes will be required to be made in immediately available funds in U.S. dollars or the Specified Currency, as the case may be, in New York City on the date of settlement. No Note will have an established trading market when issued. Unless specified in the applicable pricing supplement, ML&Co. will not list the notes on any securities exchange. The agent may from time to time purchase and sell notes in the secondary market, but the agent is not obligated to do so, and there can be S-31 no assurance that there will be a secondary market for the notes or liquidity in the secondary market if one develops. From time to time, the agent may make a market in the notes. The agent may be deemed to be an "underwriter" within the meaning of the Securities Act of 1933, as amended. ML&Co. has agreed to indemnify the agent against or to make contributions relating to certain civil liabilities, including liabilities under the Securities Act, or to contribute to payments the agent may be required to make in respect thereof. ML&Co. has agreed to reimburse the agent for certain expenses. From time to time, ML&Co. may issue and sell other securities described in the accompanying prospectus, and the amount of notes that ML&Co. may offer and sell under this prospectus supplement may be reduced as a result of such sales. In connection with the offering of notes purchased by the agent as principal on a fixed price basis, the agent is permitted to engage in certain transactions that stabilize the price of the notes. These transactions may consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the notes. If the agent creates a short position in the notes in connection with the offering, i.e., if it sells notes in an aggregate principal amount exceeding that set forth in the applicable pricing supplement, then the agent may reduce that short position by purchasing notes in the open market. In general, purchases of notes for the purpose of stabilization or to reduce a short position could cause the price of the notes to be higher than in the absence of these purchases. Neither ML&Co. nor the agent make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the notes. In addition, neither ML&Co. nor the agent makes any representation that the agent will engage in any such transactions or that such transactions, once commenced, will not be discontinued without notice. The distribution of the notes will conform to the requirements set forth in the applicable sections of Rule 2720 of the Conduct Rules of the NASD. VALIDITY OF THE NOTES The validity of the notes will be passed upon for ML&Co. and the agent by Brown & Wood LLP, New York, New York. S-32 PROSPECTUS - -------------- [LOGO] Merrill Lynch & Co., Inc.

The following information for the fiscal years 1995 through 1997 has been restated as if the two entities had always been combined. The following table sets forth our historical ratios of earnings to fixed charges and ratios of earnings to combined fixed charges and preferred stock dividends for the periods indicated:
Year Ended Last Friday in December For the Three ------------------------ Months Ended 1995 1996 1997 1998 1999 March 31, 2000 ---- ---- ---- ---- ---- -------------- Ratio of earnings to fixed charges(a)........................... 1.2 1.2 1.2 1.1 1.3 1.4 Ratio of earnings to combined fixed charges and preferred stock dividends(a)......................... 1.2 1.2 1.2 1.1 1.3 1.4
- -------- (a) The effect of combining Midland Walwyn did not change the ratios reported for the fiscal years 1995 through 1997. For the purpose of calculating the ratio of earnings to fixed charges, "earnings" consist of earnings from continuing operations before income taxes and fixed charges, excluding capitalized interest and preferred security dividend requirements. "Fixed charges" consist of interest costs, the interest factor in rentals, amortization of debt issuance costs, preferred security dividend requirements of subsidiaries, and capitalized interest.

DESCRIPTION OF DEBT SECURITIES Unless otherwise specified in a prospectus supplement, the senior debt securities are to be issued under an indenture (the "1983 Indenture"), dated as of April 1, 1983, as amended and restated through the date of this prospectus and as it may be further amended in the future, between ML&Co. and The Chase Manhattan Bank, as trustee, or issued under an indenture (the "1993 Indenture"), dated as of October 1, 1993, as amended through the date of this prospectus and as it may be further amended in the future, between ML&Co. and The Chase Manhattan Bank, as trustee (each, a "Senior Debt Trustee"). The 1983 Indenture and the 1993 Indenture are referred to as the "Senior Indentures". Unless otherwise specified in a prospectus supplement, the subordinated debt securities are to be issued under an indenture (the "Subordinated Indenture"), between ML&Co. and The Chase Manhattan Bank, as trustee (the "Subordinated Debt Trustee"). The Senior Debt Securities and Subordinated Debt Securities may also be issued under one or more other indentures (each, a "Subsequent Indenture") and have one or more other trustees (each, a "Subsequent Trustee"). Any Subsequent Indenture relating to senior debt securities will have terms and conditions identical in all material respects to the above-referenced Senior Indentures and any Subsequent Indenture relating to subordinated debt securities will have terms and conditions identical in all material respects to the above-referenced Subordinated Indenture, including, but not limited to, the applicable terms and conditions described below. Any Subsequent Indenture relating to a series of debt securities, and the applicable trustee, will be identified in the applicable prospectus supplement or term sheet. A copy of each indenture is filed, or, in the case of a Subsequent Indenture, will be filed, as an exhibit to the registration statement relating to the securities. The following summaries of the material provisions of the indentures are not complete and are subject to, and are qualified in their entirety by reference to, all provisions of the respective indentures, including the definitions of terms. Terms of the Debt Securities ML&Co. may issue the debt securities from time to time, without limitation as to aggregate principal amount and in one or more series. ML&Co. may issue debt securities upon the satisfaction of conditions, including the delivery to the applicable Trustee of a resolution of the Board of Directors of ML&Co., or a committee of the Board of Directors, or a certificate of an officer of ML&Co. who has been authorized by the Board of Directors to take that kind of action, which fixes or establishes the terms of the debt securities being issued. Any resolution or officer's certificate approving the issuance of any issue of debt securities will include the terms of that issue of debt securities, including: . the aggregate principal amount and whether there is any limit upon the aggregate principal amount that ML&Co. may subsequently issue; . the stated maturity date; 4 . the principal amount payable whether at maturity or upon earlier acceleration, and whether the principal amount will be determined with reference to an index, formula or other method; . any fixed or variable interest rate or rates per annum and any contingencies relating to changes in any applicable interest rate; . any interest payment dates; . any provisions for redemption, the redemption price and any remarketing arrangements; . any sinking fund requirements; . whether the debt securities are denominated or payable in United States dollars or a foreign currency or units of two or more foreign currencies; . the form in which ML&Co. will issue the debt securities, whether registered, bearer or both, and any restrictions applicable to the exchange of one form for another and to the offer, sale and delivery of the debt securities in either form; . whether and under what circumstances ML&Co. will pay additional amounts ("Additional Amounts") under any debt securities held by a person who is not a U.S. person for specified taxes, assessments or other governmental charges and whether ML&Co. has the option to redeem the affected debt securities rather than pay any Additional Amounts; . whether the debt securities are to be issued in global form; . the title and series designation; . the minimum denominations; . whether, and the terms and conditions relating to when, ML&Co. may satisfy all or part of its obligations with regard to payment upon maturity, or any redemption or required repurchase or in connection with any exchange provisions by delivering to the holders of the debt securities, other securities, which may or may not be issued by or be obligations of ML&Co., or a combination of cash, other securities and/or property ("Maturity Consideration"); . any additions or deletions in the terms of the debt securities with respect to the Events of Default set forth in the respective indentures; . the terms, if any, upon which the debt securities are convertible into common stock or preferred stock of ML&Co. and the terms and conditions upon which any conversion will be effected, including the initial conversion price or rate, the conversion period and any other provisions in addition to or instead of those described in this prospectus; . whether, and the terms and conditions relating to when, holders may transfer the debt securities separately from warrants if the debt securities and warrants are issued together; and . any other terms of the debt securities which are not inconsistent with the provisions of the applicable indenture. Please see the accompanying prospectus supplement or the terms sheet you have received or will receive for the terms of the specific debt securities being offered. ML&Co. may deliver this prospectus before or concurrently with the delivery of a terms sheet. ML&Co. may issue debt securities under the indentures upon the exercise of warrants to purchase debt securities. See "Description of Debt Warrants". Nothing in the indentures or in the terms of the debt securities will prohibit the issuance of securities representing subordinated indebtedness that is senior or junior to the subordinated debt securities. Prospective purchasers of debt securities should be aware that special U.S. Federal income tax, accounting and other considerations may be applicable to instruments such as the debt securities. The prospectus supplement relating to an issue of debt securities will describe these considerations, if they apply. 5 ML&Co. will issue each series of debt securities, as described in the prospectus supplement, in fully registered form without coupons, and/or in bearer form with or without coupons, and in denominations set forth in the prospectus supplement. There will be no service charge for any registration of transfer of registered debt securities or exchange of debt securities, but ML&Co. may require payment of a sum sufficient to cover any tax or other governmental charges imposed in connection with any registration of transfer or exchange. Each indenture provides that ML&Co. may issue debt securities in global form. If any series of debt securities is issued in global form, the applicable prospectus supplement will describe the circumstances, if any, under which beneficial owners of interests in any of those global debt securities may exchange their interests for debt securities of that series and of like tenor and principal amount in any authorized form and denomination. The provisions of the indentures permit ML&Co. , without the consent of holders of any debt securities, to issue additional debt securities with terms different from those of debt securities previously issued and to reopen a previous series of debt securities and issue additional debt securities of that series. The senior debt securities will be unsecured and will rank equally with all other unsecured and unsubordinated indebtedness of ML&Co. The subordinated debt securities will be unsecured and will be subordinated to all existing and future senior indebtedness of ML&Co. Because ML&Co. is a holding company, the right of ML&Co. and its creditors, including the holders of the debt securities, 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 a bankruptcy court may recognize the claims of ML&Co. itself as a creditor of the subsidiary. In addition, dividends, loans and advances from certain subsidiaries, including MLPF&S, to ML&Co. are restricted by net capital requirements under the Securities Exchange Act of 1934, as amended, and under rules of certain exchanges and other regulatory bodies. ML&Co. will pay or deliver principal and any premium, Additional Amounts, Maturity Consideration and interest in the manner, at the places and subject to the restrictions set forth in the applicable indenture, the debt securities and the applicable prospectus supplement. However, at its option, ML&Co. may pay any interest and any Additional Amounts by check mailed to the holders of registered debt securities at their registered addresses. Holders may present debt securities for exchange, and registered debt securities for registration of transfer, in the manner, at the places and subject to the restrictions set forth in the applicable indenture, the debt securities and the applicable prospectus supplement. Holders may transfer debt securities in bearer form and the coupons, if any, pertaining to the debt securities by delivery. There will be no service charge for any registration of transfer or exchange of debt securities, but ML&Co. may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange. Unless otherwise indicated in the applicable prospectus supplement, ML&Co. will issue the debt securities under the indentures. If so specified in a prospectus supplement, ML&Co. may issue subordinated debt securities under a separate indenture which provides for a single issue of zero coupon convertible subordinated debt securities, a form of which is filed as an exhibit to the registration statement of which this prospectus is a part. If ML&Co. issues debt securities under any indenture, the applicable prospectus supplement will set forth the terms of the debt securities and will identify the applicable indenture and trustee. Merger and Consolidation ML&Co. may consolidate or merge with or into any other corporation, and ML&Co. may sell, lease or convey all or substantially all of its assets to any corporation, provided that: . the resulting corporation, if other than ML&Co., is a corporation organized and existing under the laws of the United States of America or any U.S. state and assumes all of ML&Co.'s obligations to: 6 . pay or deliver the principal of, and any premium, Additional Amounts, Maturity Consideration or interest on, the debt securities; and . perform and observe all of ML&Co.'s other obligations under the indentures, and . ML&Co. or any successor corporation, as the case may be, is not, immediately after any consolidation or merger, in default under the indentures. Modification and Waiver Each indenture may be modified and amended by ML&Co. and the applicable trustee with the consent of holders of at least 66 2/3% in principal amount or aggregate issue price of each series of debt securities affected. However, without the consent of each holder of any debt security affected, no amendment or modification to any indenture may: . change the stated maturity of the principal or Maturity Consideration of, or any installment of interest or Additional Amounts on, any debt security or any premium payable on redemption, or change the redemption price; . reduce the principal amount of, or the interest or Additional Amounts payable on, or reduce the amount or change the type of Maturity Consideration deliverable on, any debt security or reduce the amount of principal or Maturity Consideration which could be declared due and payable before the stated maturity; . change the place or currency of any delivery or payment of principal or Maturity Consideration of, or any premium, interest or Additional Amounts on any debt security; . impair the right to institute suit for the enforcement of any delivery or payment on any debt security; . reduce the percentage in principal amount or aggregate issue price of the outstanding debt securities of any series, the consent of whose holders is required to modify or amend the applicable indenture; or . modify the foregoing requirements or reduce the percentage in principal amount or aggregate issue price of outstanding debt securities necessary to waive any past default to less than a majority. No modification or amendment of the Subordinated Indenture or any Subsequent Indenture for subordinated debt securities may adversely affect the rights of any holder of ML&Co.'s senior indebtedness without the consent of each holder affected. The holders of at least a majority in principal amount or aggregate issue price of the outstanding debt securities of any series may, with respect to that series, waive past defaults under the applicable indenture and waive compliance by ML&Co. with certain provisions of that indenture, except as described under "--Events of Default". Events of Default Each of the following will be an Event of Default with respect to each series of debt securities issued under each indenture: . default in the payment of any interest or Additional Amounts when due, and continuing for 30 days; . default in the payment of any principal or premium, when due; . default in the delivery or payment of the Maturity Consideration when due; . default in the deposit of any sinking fund payment, when due; . default in the performance of any other obligation of ML&Co. contained in the applicable indenture for the benefit of that series or in the debt securities of that series, and continuing for 60 days after written notice as provided in the applicable indenture; 7 . specified events in bankruptcy, insolvency or reorganization of ML&Co.; and . any other Event of Default provided with respect to debt securities of that series. If an Event of Default occurs and is continuing for any series of debt securities, the applicable trustee or the holders of at least 25% in principal amount or aggregate issue price of the outstanding debt securities of that series may declare all amounts, or any lesser amount provided for in the debt securities of that series, due and payable or deliverable immediately. At any time after the applicable trustee or the holders have made a declaration of acceleration with respect to the debt securities of any series but before the applicable trustee has obtained a judgment or decree for payment of money due, the holders of a majority in principal amount or aggregate issue price of the outstanding debt securities of that series may rescind any declaration of acceleration and its consequences, provided that all payments and/or deliveries due, other than those due as a result of acceleration, have been made and all Events of Default have been remedied or waived. The holders of a majority in principal amount or aggregate issue price of the outstanding debt securities of any series may waive an Event of Default with respect to that series, except a default: . in the payment of any amounts due and payable or deliverable under the debt securities of that series; or . in respect of an obligation of ML&Co. contained in, or a provision of, any indenture which cannot be modified under the terms of that indenture without the consent of each holder of each series of debt securities affected. The holders of a majority in principal amount or aggregate issue price of the outstanding debt securities of a series may direct the time, method and place of conducting any proceeding for any remedy available to the applicable trustee or exercising any trust or power conferred on the trustee with respect to debt securities of that series, provided that any direction is not in conflict with any rule of law or the applicable indenture. Subject to the provisions of each indenture relating to the duties of the appropriate trustee, before proceeding to exercise any right or power under an indenture at the direction of the holders, the applicable trustee is entitled to receive from those holders reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in complying with any direction. Unless otherwise stated in the applicable prospectus supplement, any series of debt securities issued under any indenture will not have the benefit of any cross-default provisions with other indebtedness of ML&Co. ML&Co. will be required to furnish to each trustee annually a statement as to the fulfillment by ML&Co. of all of its obligations under the applicable indenture. Special Terms Relating to the Senior Debt Securities Limitations Upon Liens ML&Co. may not, and may not permit any majority-owned subsidiary to, create, assume, incur or permit to exist any indebtedness for borrowed money secured by a pledge, lien or other encumbrance, other than any lien specifically permitted by the Senior Indentures, on the Voting Stock owned directly or indirectly by ML&Co. of any majority-owned subsidiary, other than a majority-owned subsidiary which, at the time of incurrence of the secured indebtedness, has a net worth of less than $3,000,000, unless the outstanding senior debt securities are secured equally and ratably with the secured indebtedness. "Voting Stock" is defined in the Senior Indentures as the stock of the class or classes having general voting power under ordinary circumstances to elect at least a majority of the board of directors, managers or trustees of a corporation provided that, for the purposes of the Senior Indentures, stock that carries only the right to vote conditionally on the occurrence of an event is not considered voting stock whether or not the event has happened. 8 Limitations on Disposition of Voting Stock of, and Merger and Sale of Assets by, MLPF&S ML&Co. 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 the transaction, MLPF&S remains a Controlled Subsidiary. "Controlled Subsidiary" is defined in the Senior Indentures to mean a corporation more than 80% of the outstanding shares of Voting Stock of which are owned directly or indirectly by ML&Co. In addition, ML&Co. may not permit MLPF&S to: . merge or consolidate, unless the surviving company is a Controlled Subsidiary, or . convey or transfer its properties and assets substantially as an entirety, except to one or more Controlled Subsidiaries. Special Terms Relating to the Subordinated Debt Securities Upon any distribution of assets of ML&Co. resulting from any dissolution, winding up, liquidation or reorganization, payments on subordinated debt securities are subordinated to the extent provided in the Subordinated Indenture in right of payment to the prior payment in full of all senior indebtedness, but the obligation of ML&Co. to make payments on the subordinated debt securities will not otherwise be affected. ML&Co. may not make any payment on subordinated debt securities at any time when there is a default in the payment or delivery of any amounts due on any senior indebtedness, including payment of any sinking fund. Because the subordinated debt securities are subordinated in right of payment to any senior indebtedness, in the event of a distribution of assets upon insolvency, some creditors of ML&Co. may recover more, ratably, than holders of subordinated debt securities. Holders of subordinated debt securities will be subrogated to the rights of holders of senior indebtedness to the extent of payments made on senior indebtedness upon any distribution of assets in any proceedings in respect of subordinated debt securities. As of March 31, 2000, a total of approximately $85.0 billion of ML&Co.'s indebtedness was senior indebtedness. Special Terms Relating to Convertible Debt Securities The following provisions will apply to debt securities that will be convertible into common stock or preferred stock of ML&Co. unless otherwise provided in the prospectus supplement relating to the specific issue of debt securities. The holder of any convertible debt securities will have the right, exercisable at any time during the time period specified in the applicable prospectus supplement, unless previously redeemed, to convert convertible debt securities into shares of common stock or preferred stock of ML&Co. as specified in the prospectus supplement, at the conversion rate per principal amount of convertible debt securities set forth in the applicable prospectus supplement. In the case of convertible debt securities called for redemption, conversion rights will expire at the close of business on the date fixed for the redemption specified in the applicable prospectus supplement, except that, in the case of redemption at the option of the holder, if applicable, the conversion right will terminate upon receipt of written notice of the exercise of the option. For each series of convertible debt securities, the conversion price or rate will be subject to adjustment as contemplated in the applicable indenture. Unless otherwise provided in the applicable prospectus supplement, these adjustments may occur as a result of: . the issuance of shares of ML&Co. common stock as a dividend; . subdivisions and combinations of ML&Co. common stock; 9 . the issuance to all holders of ML&Co. common stock of rights or warrants entitling holders to subscribe for or purchase shares of ML&Co. common stock at a price per share less than the current market price per share; and . the distribution to all holders of ML&Co. common stock of: . shares of ML&Co. capital stock other than common stock; . evidences of indebtedness of ML&Co. or assets other than cash dividends paid from retained earnings and dividends payable in common stock referred to above; or . subscription rights or warrants other than those referred to above. In any case, no adjustment of the conversion price or rate will be required unless an adjustment would require a cumulative increase or decrease of at least 1% in such price or rate. ML&Co. will not issue any fractional shares of ML&Co. common stock upon conversion, but, instead, ML&Co. will pay a cash adjustment. If indicated in the applicable prospectus supplement, convertible debt securities convertible into common stock of ML&Co. which are surrendered for conversion between the record date for an interest payment, if any, and the interest payment date, other than convertible debt securities called for redemption on a redemption date during that period, must be accompanied by payment of an amount equal to interest which the registered holder is entitled to receive. ML&Co. will determine the adjustment provisions for convertible debt securities at the time of issuance of each series of convertible debt securities. These adjustment provisions will be described in the applicable prospectus supplement. Except as set forth in the applicable prospectus supplement, any convertible debt securities called for redemption, unless surrendered for conversion on or before the close of business on the redemption date, are subject to being purchased from the holder of the convertible debt securities by one or more investment banking firms or other purchasers who may agree with ML&Co. to purchase convertible debt securities and convert them into common stock or preferred stock of ML&Co., as the case may be. Governing Law The indentures and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York. DESCRIPTION OF DEBT WARRANTS ML&Co. may issue warrants for the purchase of debt securities ("Debt Warrants"). The Debt Warrants are to be issued under debt warrant agreements to be entered into between ML&Co. and a bank or trust company, as debt warrant agent as set forth in the prospectus supplement relating to the specific issue of Debt Warrants being offered. We have filed a copy of the form of debt warrant agreement, including the form of warrant certificates representing the Debt Warrants, reflecting the alternative provisions to be included in the debt warrant agreements that will be entered into with respect to particular offerings of Debt Warrants, as an exhibit to the registration statement of which this prospectus is a part. The following summaries of the material provisions of the debt warrant agreement and the debt warrant certificates are not complete and are subject to, and are qualified in their entirety by reference to, all the provisions of the debt warrant agreement and the debt warrant certificates, respectively, including the definitions of terms. Terms of the Debt Warrants The applicable prospectus supplement will describe the terms of the specific issue of Debt Warrants being offered, the debt warrant agreement relating to the Debt Warrants and the debt warrant certificates representing the Debt Warrants, including the following: 10 . the designation and aggregate principal amount of the debt securities that the holder of a Debt Warrant may purchase upon exercise of the Debt Warrant and the price at which the purchase may be made; . the designation and terms of any debt securities issued with or purchasable upon exercise of the Debt Warrants, including whether the debt securities will be senior debt securities or subordinated debt securities and under which indenture the debt securities will be issued; . the procedures and conditions relating to the exercise of the Debt Warrants; . the number of Debt Warrants issued with each debt security; . any date on and after which the Debt Warrants and any related debt securities are separately transferable; . the date on which the right to exercise the Debt Warrants begins and expires; . whether the Debt Warrants represented by the debt warrant certificates will be issued in registered or bearer form, and, if registered, where they may be transferred and registered; . any circumstances which will cause the Debt Warrants to be deemed to be automatically exercised; . the identity of the debt warrant agent; and . any other terms of the Debt Warrants which are not inconsistent with the provisions of the debt warrant agreement. Holders may exchange debt warrant certificates for new debt warrant certificates of different denominations. Holders may exercise Debt Warrants at the corporate trust office of the debt warrant agent or any other office indicated in the applicable prospectus supplement. Before the exercise of their Debt Warrants, holders of Debt Warrants will not have any of the rights of holders of the debt securities that may be purchased upon exercise of the Debt Warrants and will not be entitled to payment or delivery of any amounts which may be due on the debt securities purchasable upon exercise of the Debt Warrants. Prospective purchasers of Debt Warrants should be aware that special U.S. Federal income tax, accounting and other considerations may be applicable to instruments such as Debt Warrants and to the debt securities purchasable upon exercise of the Debt Warrants. The prospectus supplement relating to any issue of Debt Warrants will describe these considerations. Ranking The Debt Warrants are unsecured contractual obligations of ML&Co. and will rank equally with its other unsecured contractual obligations and with its unsecured and unsubordinated debt. Because ML&Co. is a holding company, the right of ML&Co. and its creditors, including the debt warrantholders, 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 a bankruptcy court may recognize claims of ML&Co. itself as a creditor of the subsidiary. In addition, dividends, loans and advances from certain subsidiaries, including MLPF&S, to ML&Co. are restricted by net capital requirements under the Exchange Act and under rules of certain exchanges and other regulatory bodies. Book-Entry Procedures Except as may otherwise be provided in the applicable prospectus supplement, the Debt Warrants will be issued in the form of global debt warrant certificates, registered in the name of a depositary or its nominee. 11 Except as may otherwise be provided in the applicable prospectus supplement, beneficial owners will not be entitled to receive definitive certificates representing Debt Warrants unless the depositary is unwilling or unable to continue as depositary or ML&Co. decides to have the Debt Warrants represented by definitive certificates. A beneficial owner's interest in a Debt Warrant will be recorded on or through the records of the brokerage firm or other entity that maintains the beneficial owner's account. In turn, the total number of Debt Warrants held by an individual brokerage firm for its clients will be maintained on the records of the depositary in the name of the brokerage firm or its agent. Transfer of ownership of any Debt Warrant will be effected only through the selling beneficial owner's brokerage firm. Exercise of Debt Warrants Each Debt Warrant will entitle the holder to purchase for cash a principal amount of debt securities at the exercise price set forth in, or determined in the manner set forth in, the applicable prospectus supplement. Holders may exercise Debt Warrants at any time up to the close of business on the expiration date set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised Debt Warrants will become void. Holders may exercise Debt Warrants in the manner described in the applicable prospectus supplement. Upon receipt of payment and properly completed and duly executed debt warrant certificate at the corporate trust office of the debt warrant agent or any other office indicated in the applicable prospectus supplement, ML&Co. will, as soon as practicable, forward the debt securities purchased. If less than all of the Debt Warrants represented by any debt warrant certificate are exercised, a new debt warrant certificate will be issued for the remaining amount of Debt Warrants. Listing ML&Co. may list an issue of Debt Warrants on a national securities exchange. Any listing will be specified in the applicable prospectus supplement. DESCRIPTION OF CURRENCY WARRANTS ML&Co. may issue Currency Warrants either in the form of: . Currency Put Warrants entitling the holders to receive from ML&Co. the cash settlement value in U.S. dollars of the right to sell a specified amount of a specified foreign currency or currency units for a specified amount of U.S. dollars, or . Currency Call Warrants entitling the holders to receive from ML&Co. the cash settlement value in U.S. dollars of the right to purchase a specified amount of a specified foreign currency or units of two or more currencies for a specified amount of U.S. dollars. ML&Co. may issue the Currency Warrants under a currency put warrant agreement or a currency call warrant agreement, as applicable, to be entered into between ML&Co. and a bank or trust company, as currency warrant agent as set forth in the applicable prospectus supplement relating to Currency Warrants being offered. Copies of the forms of currency put warrant agreement and currency call warrant agreement, including the forms of certificates representing the Currency Put Warrants and Currency Call Warrants, reflecting the provisions to be included in the currency warrant agreements that will be entered into with respect to particular offerings of Currency Warrants, are filed as exhibits to the registration statement of which this prospectus is a part. The following summaries of the material provisions of the currency warrant agreements and the currency warrant certificates are not complete and are subject to, and are qualified in their entirety by reference to, all the provisions of the currency warrant agreements and the currency warrant certificates, respectively, including the definitions of terms. 12 Terms of the Currency Warrants The applicable prospectus supplement will describe the terms of the specific issue of Currency Warrants being offered, the currency warrant agreement relating to the Currency Warrants and the currency warrant certificates representing the Currency Warrants, including the following: . whether the Currency Warrants are Currency Put Warrants, Currency Call Warrants, or both; . the formula for determining the cash settlement value of each Currency Warrant; . the procedures and conditions relating to the exercise of the Currency Warrants; . any circumstances other than those described below under "--Exercise of Currency Warrants" and "--Listing"that will cause the Currency Warrants to be deemed to be automatically exercised; . any minimum number of Currency Warrants which must be exercised at any one time, other than upon automatic exercise; . the date on which the right to exercise the Currency Warrants begins and expires; . the identity of the currency warrant agent; and . any other terms of the Currency Warrants that are not inconsistent with the provisions of the applicable currency warrant agreement. Prospective purchasers of Currency Warrants should be aware that special U.S. Federal income tax, accounting and other considerations may be applicable to instruments such as Currency Warrants. The prospectus supplement relating to any issue of Currency Warrants will describe these considerations, if they apply. Ranking The Currency Warrants are unsecured contractual obligations of ML&Co. and will rank equally with its other unsecured contractual obligations and with its unsecured and unsubordinated debt. Because ML&Co. is a holding company, the right of ML&Co. and its creditors, including the currency warrantholders, 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 a bankruptcy court may recognize claims of ML&Co. itself as a creditor of the subsidiary. In addition, dividends, loans and advances from certain subsidiaries, including MLPF&S, to ML&Co. are restricted by net capital requirements under the Exchange Act and under rules of certain exchanges and other regulatory bodies. Book-Entry Procedures Except as may otherwise be provided in the applicable prospectus supplement, the Currency Warrants will be issued in the form of global currency warrant certificates, registered in the name of a depositary or its nominee. In that case, beneficial owners will not be entitled to receive definitive certificates representing Currency Warrants unless the depositary is unwilling or unable to continue as depositary or ML&Co. decides to have the Currency Warrants represented by definitive certificates. A beneficial owner's interest in a Currency Warrant will be recorded on or through the records of the brokerage firm or other entity that maintains a beneficial owner's account. In turn, the total number of Currency Warrants held by an individual brokerage firm for its clients will be maintained on the records of the depositary in the name of the brokerage firm or its agent. Transfer of ownership of any Currency Warrant will be effected only through the selling beneficial owner's brokerage firm. 13 Exercise of Currency Warrants Each Currency Warrant will entitle the holder to the cash settlement value of that Currency Warrant on the applicable exercise date as described in the applicable prospectus supplement. If a Currency Warrant has more than one exercise date and is not exercised before the time specified in the applicable prospectus supplement, on the fifth business day preceding the expiration date, the Currency Warrants will be deemed automatically exercised. Listing ML&Co. will apply to list each issue of Currency Warrants on a national securities exchange. In the event that the Currency Warrants are delisted from, or permanently suspended from trading on, any exchange, the expiration date for the exercise of the Currency Warrants will be the date the delisting or trading suspension becomes effective and Currency Warrants not previously exercised will be deemed automatically exercised on the business day immediately preceding the expiration date. Under the applicable currency warrant agreement, ML&Co. will agree not to seek delisting of the Currency Warrants, or suspension of their trading, on any exchange. DESCRIPTION OF INDEX WARRANTS ML&Co. may issue from time to time Index Warrants consisting of index put warrants or index call warrants. Subject to applicable law, ML&Co. will pay or deliver consideration on each Index Warrant in an amount determined by reference to the level or value of an index such as: . an equity or debt security, or a portfolio or basket of indices or securities, which may include the price or yield of securities; . any statistical measure of economic or financial performance, which may include any currency or consumer price, or mortgage index; or . the price or value of any commodity or any other item or index or any combination. The payment or delivery of any consideration on any index put warrant will be determined by the decrease in the level or value of the applicable index and the payment or delivery of any consideration on any index call warrant will be determined by the increase in the level or value of the applicable Index. Method of Issuance Index Warrants issued without a Minimum Expiration Value will be issued under one or more index warrant agreements to be entered into between ML&Co. and a bank or trust company, as index warrant agent, all as described in the prospectus supplement relating to the specific issue of Index Warrants. The index warrant agent will act solely as the agent of ML&Co. under the applicable index warrant agreement and will not assume any obligation or relationship of agency or trust for or with any index warrantholders. A single bank or trust company may act as index warrant agent for more than one issue of Index Warrants. 14 Index Warrants issued with a Minimum Expiration Value will be issued under one or more index warrant trust indentures to be entered into between ML&Co. and a corporation or other person permitted by the Trust Indenture Act of 1939, as amended from time to time, to act as index warrant trustee, all as described in the prospectus supplement relating to the Index Warrants. Any index warrant trust indenture will be qualified under the Trust Indenture Act. To the extent allowed by the Trust Indenture Act, a single qualified corporation may act as index warrant trustee for more than one issue of Index Warrants. ML&Co. has filed forms of index warrant agreement and index warrant trust indenture and the related global index warrant certificates as exhibits to the registration statement of which this prospectus is a part. The summaries set forth in this section of the material provisions of the index warrant agreement, the index warrant trust indenture and global index warrant certificates are not complete, are subject to, and are qualified in their entirety by reference to, all the provisions of the index warrant agreement, the index warrant trust indenture and global index warrant certificates, respectively. Unless otherwise specified in the accompanying prospectus supplement, payments, if any, upon exercise of the Index Warrants will be made in U.S. dollars. The Index Warrants will be offered on terms to be determined at the time of sale. ML&Co. will have the right to reopen a previous issue of Index Warrants and to issue additional Index Warrants of that issue without the consent of any index warrantholder. Terms of the Index Warrants The applicable prospectus supplement will describe the specific issue of Index Warrants being offered, the indenture or agreement under which the Index Warrants will be issued, as the case may be, and the index warrant certificates representing the Index Warrants, including the following: . whether the Index Warrants to be issued will be Index Put Warrants, Index Call Warrants or both; . the aggregate number and initial public offering price or purchase price; . the applicable index; . whether the Index Warrants will be deemed automatically exercised as of a specified date or whether the Index Warrants may be exercised during a period and the date on which the right to exercise the Index Warrants commences and expires; . the manner in which the Index Warrants may be exercised and any restrictions on, or other special provisions relating to, the exercise of the Index Warrants; . any minimum number of the Index Warrants exercisable at any one time; . any maximum number of the Index Warrants that may, subject to ML&Co.'s election, be exercised by all index warrantholders, or by any person or entity, on any day; . any provisions permitting an index warrantholder to condition an exercise notice on the absence of certain specified changes in the level of the applicable index after the exercise date, any provisions permitting ML&Co. to suspend exercise of the Index Warrants based on market conditions or other circumstances and any other special provision relating to the exercise of the Index Warrants; . any provisions for the automatic exercise of the Index Warrants other than at the expiration date; . any provisions permitting ML&Co. to cancel the Index Warrants upon the occurrence of certain events; . any additional circumstances that would constitute an Event of Default under the Index Warrants; . the method of determining: . the payment or delivery, if any, to be made in connection with the exercise or deemed exercise of the Index Warrants (the "Settlement Value"); 15 . the minimum payment or delivery, if any, to be made upon expiration of the Index Warrants (the "Minimum Expiration Value"); . the payment or delivery to be made upon the exercise of any right which ML&Co. may have to cancel the Index Warrants; and . the value of the index; . in the case of Index Warrants relating to an index for which the trading prices of underlying securities, commodities or rates are expressed in a foreign currency, the method of converting amounts in the relevant foreign currency or currencies into U.S. dollars, or any other currency or composite currency in which the Index Warrants are payable; . any method of providing for a substitute index or otherwise determining the payment or delivery to be made in connection with the exercise of the Index Warrants if the index changes or ceases to be made available by its publisher; . any time or times at which ML&Co. will make payment or delivery on the Index Warrants following exercise or automatic exercise; . any provisions for issuing the Index Warrants in other than book-entry form; . if the Index Warrants are not issued in book-entry form, any place or places at which ML&Co. will make payment or delivery on cancellation and any Minimum Expiration Value of the Index Warrants; . any circumstances that will cause the Index Warrants to be deemed to be automatically exercised; . any material risk factors relating to the Index Warrants; . the identity of the Index Warrant Agent; and . any other terms of the Index Warrants which are not inconsistent with the provisions of the index warrant agreement. Prospective purchasers of Index Warrants should be aware that special U.S. Federal income tax, accounting and other considerations may be applicable to instruments such as the Index Warrants. The prospectus supplement relating to any issue of Index Warrants will describe these considerations, if they apply. Ranking The Index Warrants are unsecured contractual obligations of ML&Co. and will rank equally with its other unsecured contractual obligations and with its unsecured and unsubordinated debt. Because ML&Co. is a holding company, the right of ML&Co. and its creditors, including the index warrantholders, 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 a bankruptcy court may recognize claims of ML&Co. itself as a creditor of the subsidiary. In addition, dividends, loans and advances from certain subsidiaries, including MLPF&S, to ML&Co. are restricted by net capital requirements under the Exchange Act and under rules of certain exchanges and other regulatory bodies. Payment and Delivery If specified, and under the circumstances described in the prospectus supplement: . ML&Co. will pay or deliver to each index warrantholder an amount equal to the greater of the applicable Settlement Value and a Minimum Expiration Value of the Index Warrants; . upon cancellation of the Index Warrants by ML&Co. which may occur upon specified events, ML&Co. will pay or deliver to each index warrantholder an amount specified in the prospectus supplement; and 16 . following the occurrence of an extraordinary event, the Settlement Value of an Index Warrant may, at the option of ML&Co., be determined on a different basis, including in connection with automatic exercise at expiration. Unless otherwise specified in the related prospectus supplement, the Index Warrants will be deemed to be automatically exercised upon expiration or any earlier date that may be specified. Upon any automatic exercise, ML&Co. will deliver or pay to each index warrantholder an amount equal to the Settlement Value of the Index Warrants, except that holders of Index Warrants having a Minimum Expiration Value will be entitled to receive a payment or delivery equal to the greater of the Settlement Value and the applicable Minimum Expiration Value. The Minimum Expiration Value may be either a predetermined payment or delivery or a payment or delivery that varies during the term of the Index Warrants in accordance with a schedule or formula. Any Minimum Expiration Value applicable to an issue of Index Warrants, as well as any additional circumstances resulting in the automatic exercise of the Index Warrants, will be specified in the applicable prospectus supplement. Cancellation or Postponement If so specified in the applicable prospectus supplement, ML&Co. may cancel the Index Warrants. In addition, ML&Co. may delay or postpone the exercise or valuation of, or payment or delivery for, the Index Warrants upon the occurrence of an extraordinary event. Any extraordinary events relating to an issue of Index Warrants will be described in the applicable prospectus supplement. Upon cancellation, the related index warrantholders will be entitled to receive only the applicable payment or delivery on cancellation specified in the applicable prospectus supplement. The amount payable or deliverable upon cancellation may be either a predetermined amount or an amount that varies during the term of the Index Warrants in accordance with a schedule or formula. Waiver of Default If ML&Co. defaults with respect to any of its obligations under any Index Warrants issued with a Minimum Expiration Value under an index warrant trust indenture, the index warrantholders of a majority in interest of all outstanding Index Warrants may waive a default, except a default: . in the payment or delivery of the Settlement Value, Minimum Expiration Value or payment or delivery of any amount upon cancellation of the Index Warrants; or . in respect of a covenant or provision of the applicable index warrant trust indenture which cannot be modified or amended without the consent of each index warrantholder of each outstanding Index Warrant affected. Modification ML&Co. and the index warrant agent or index warrant trustee, as the case may be, may amend any index warrant agreement or index warrant indenture and the terms of the related Index Warrants by a supplemental agreement or supplemental indenture (each, a "Supplemental Agreement"), without the consent of the holders of any Index Warrants, for the purpose of: . curing any ambiguity, or of curing, correcting or supplementing any defective or inconsistent provision, or of making any other provisions with respect to matters or questions arising under the index warrant agreement or index warrant trust indenture, as the case may be, which are not inconsistent with the provisions of the respective agreement or indenture or of the Index Warrants; . evidencing the succession to ML&Co. and the assumption by the successor of ML&Co.'s covenants contained in the index warrant agreement or the index warrant trust indenture, as the case may be, and the Index Warrants; . appointing a successor depositary; 17 . evidencing and providing for the acceptance of appointment by a successor index warrant agent or index warrant trustee with respect to the Index Warrants, as the case may be; . adding to the covenants of ML&Co., for the benefit of the index warrantholders or surrendering any right or power conferred upon ML&Co. under the index warrant agreement or index warrant trust indenture, as the case may be; . issuing Index Warrants in definitive form; or . amending the index warrant agreement or index warrant trust indenture, as the case may be, in any manner which ML&Co. may deem to be necessary or desirable and which will not materially and adversely affect the interests of the index warrantholders. ML&Co. and the index warrant agent may also amend any index warrant agreement or index warrant trust indenture, as the case may be, and the terms of the related Index Warrants, by a Supplemental Agreement, with the consent of the index warrantholders holding not less than 66 2/3% in number of the then outstanding unexercised Index Warrants affected by the amendment, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the index warrant agreement or index warrant trust indenture, as the case may be, or of modifying in any manner the rights of the index warrantholders. However, without the consent of each index warrantholder affected, no amendment may be made that: . changes the determination, or any aspects of the determination, of the Settlement Value or any payment or delivery to be made on cancellation, or any Minimum Expiration Value of the Index Warrants so as to reduce the payment or delivery to be made upon exercise or deemed exercise, . shortens the period of time during which the Index Warrants may be exercised, or otherwise materially and adversely affects the exercise rights of the index warrantholders, or . reduces the number of outstanding Index Warrants, the consent of whose holders is required for amendment of the index warrant agreement, the index warrant trust indenture or the terms of the related Index Warrants. Events of Default Specified events in bankruptcy, insolvency or reorganization of ML&Co. will constitute Events of Default with respect to Index Warrants having a Minimum Expiration Value which are issued under an index warrant trust indenture. Upon the occurrence of an Event of Default, the holders of 25% of unexercised Index Warrants may elect to receive a settlement payment or delivery for any unexercised Index Warrants. Any settlement payment or delivery will immediately become due to the index warrantholders upon any election. Assuming ML&Co. is able to satisfy its obligations when due under the Index Warrants, the settlement payment or delivery will be an amount equal to the market value of the Index Warrants as of the date ML&Co. is notified of the intended liquidation. The market value of the Index Warrants will be determined by a nationally recognized securities broker-dealer unaffiliated with ML&Co. and mutually selected by ML&Co. and the index warrant trustee. Merger, Consolidation, Sale, Lease or Other Dispositions ML&Co. may consolidate or merge with or into any other corporation and ML&Co. may sell, lease or convey all or substantially all of its assets to any corporation, provided that: . the resulting corporation, if other than ML&Co., is a corporation organized and existing under the laws of the United States of America or any U.S. state and assumes all of ML&Co.'s obligations to: . pay or deliver the Settlement Value, any Minimum Expiration Value or any consideration payable or deliverable upon cancellation, if applicable with respect to all the unexercised Index Warrants; and 18 . perform and observe all of the obligations and conditions of the index warrant agreement or index warrant trust indenture, as the case may be, to be performed or observed by ML&Co.; and . ML&Co. or the successor corporation, as the case may be, is not, immediately after any merger or consolidation, in default under the index warrant agreement or index warrant trust indenture, as the case may be. Enforceability of Rights by Index Warrantholders Any index warrantholder may, without the consent of the related index warrant agent, enforce by appropriate legal action, in and for its own behalf, its right to exercise, and receive payment or delivery for, its Index Warrants. Book-Entry Procedures Except as may otherwise be provided in the applicable prospectus supplement, the Index Warrants will be issued in book-entry form and represented by global Index Warrants, registered in the name of a depositary or its nominee. In that case, index warrantholders will not be entitled to receive definitive certificates representing Index Warrants, unless the depositary is unwilling or unable to continue as depositary or ML&Co. decides to have the Index Warrants represented by definitive certificates. A beneficial owner's interest in an Index Warrant represented by a global Index Warrant will be recorded on or through the records of the brokerage firm or other entity that maintains the beneficial owner's account. In turn, the total number of Index Warrants held by an individual brokerage firm or other entity for its clients will be maintained on the records of the depositary in the name of the brokerage firm or other entity or its agent. Transfer of ownership of any Index Warrant will be effected only through the selling beneficial owner's brokerage firm. Listing ML&Co. may list an issue of Index Warrants on a national securities exchange. Any listing will be specified in the applicable prospectus supplement. DESCRIPTION OF PREFERRED STOCK The following description sets forth certain general terms of preferred stock which ML&Co. may issue. The terms of any series of the preferred stock will be described in the applicable prospectus supplement relating to the preferred stock being offered. The description set forth below and in any prospectus supplement is not complete, and is subject to, and qualified in its entirety by reference to, ML&Co.'s restated certificate of incorporation, as amended, which is filed as an exhibit to the registration statement of which this prospectus is a part, and the certificate of designations relating to each particular series of the preferred stock, which was or will be filed with the SEC at or before the issuance of the series of preferred stock. Terms of the Preferred Stock Under ML&Co.'s restated certificate of incorporation, ML&Co. is authorized to issue up to 25,000,000 shares of preferred stock, par value $1.00 per share. The Board of Directors of ML&Co. has the authority, without approval of the stockholders, to issue all of the shares of preferred stock which are currently authorized in one or more series and to fix the number of shares and the rights, preferences, privileges, qualifications, restrictions and limitations of each series. As of March 31, 2000, ML&Co. had 24,957,500 shares of preferred stock available for issuance. ML&Co. has authorized the issuance of shares of Series A junior preferred stock, par value $1.00 per share, of ML&Co. upon exercise of preferred share purchase rights associated with each share of common stock outstanding. See "Description of Common Stock--Rights to Purchase Series A Junior Preferred Stock". 19 In addition, as described under "Description of Depositary Shares", ML&Co., at its option, instead of offering full shares of any series of preferred stock, may offer depositary shares evidenced by depositary receipts, each representing a fraction of a share of the particular series of preferred stock issued and deposited with a depositary. The fraction of a share of preferred stock which each depositary share represents will be set forth in the prospectus supplement relating to the depositary shares. The applicable prospectus supplement will describe the terms of each series of preferred stock, including, where applicable, the following: . the designation, stated value, liquidation preference and number of shares offered; . the offering price or prices; . the dividend rate or rates, or method of calculation, the dividend periods, the date on which dividends shall be payable and whether dividends are cumulative or noncumulative and, if cumulative, the dates from which dividends begin to cumulate; . any redemption or sinking fund provisions; . any conversion or exchange provisions; . any voting rights; . whether the preferred stock will be issued in certificated or book-entry form; . whether the preferred stock will be listed on a national securities exchange; . information with respect to any book-entry procedures; and . any additional rights, preferences, privileges, limitations and restrictions of the preferred stock which are not inconsistent with the provisions of the certificate of incorporation. The preferred stock will be, when issued against payment, fully paid and nonassessable. Holders will have no preemptive rights to subscribe for any additional securities which ML&Co. may issue. Unless otherwise specified in the applicable prospectus supplement, the shares of each series of preferred stock will rank equally with all other outstanding series of preferred stock issued by ML&Co. as to payment of dividends, other than with respect to cumulation of dividends, and as to the distribution of assets upon liquidation, dissolution, or winding up of ML&Co. As of March 31, 2000, there were 42,500 shares of ML&Co.'s 9% Cumulative Preferred Stock, Series A (the "9% Preferred Stock") represented by 17,000,000 depositary shares and one Special Voting Share outstanding. See "--Outstanding Preferred Stock". Each series of preferred stock will rank senior to the common stock, and any other stock of ML&Co. that is expressly made junior to that series of preferred stock. Unless otherwise specified in the applicable prospectus supplement, Citibank, N.A., will be the transfer agent, dividend disbursing agent and registrar for the shares of the preferred stock. Because ML&Co. is a holding company, its rights and the rights of holders of its securities, including the holders of preferred stock, to participate in the distribution of assets of any subsidiary of ML&Co. upon its liquidation or recapitalization will be subject to the prior claims of the subsidiary's creditors and preferred stockholders, except to the extent ML&Co. may itself be a creditor with recognized claims against the subsidiary or a holder of preferred stock of the subsidiary. Dividends and Distributions Holders of shares of the preferred stock will be entitled to receive, as, if and when declared by the Board of Directors of ML&Co., or a duly authorized committee of the Board of Directors, out of funds legally available for the payment of dividends, cash dividends at the rate set forth in, or calculated in accordance with the formula set forth in, the prospectus supplement relating to the preferred stock being offered. 20 Dividends on the preferred stock may be cumulative or noncumulative as provided in the applicable prospectus supplement. Dividends on the cumulative preferred stock will accumulate from the date of original issue and will be payable quarterly in arrears on the dates specified in the applicable prospectus supplement. If any date so specified as a dividend payment date is not a business day, declared dividends on the preferred stock will be paid on the immediately succeeding business day, without interest. The applicable prospectus supplement will set forth the applicable dividend period with respect to a dividend payment date. If the Board of Directors of ML&Co. or a duly authorized committee of the Board of Directors, fails to declare a dividend on any series of noncumulative preferred stock for any dividend period, ML&Co. will have no obligation to pay a dividend for that period, whether or not dividends on that series of noncumulative preferred stock are declared for any future dividend period. Unless otherwise specified in the applicable prospectus supplement, dividends on the preferred stock will be payable to record holders as they appear on the stock books of ML&Co. on each record date, not more than 30 nor less than 15 days preceding the applicable payment date, as shall be fixed by the Board of Directors of ML&Co. or a duly authorized committee of the Board of Directors. No dividends will be declared or paid or set apart for payment on the preferred stock of any series ranking, as to dividends, equally with or junior to any other series of preferred stock for any period unless dividends have been or are contemporaneously declared and paid or declared and a sum sufficient for the payment of those dividends has been set apart for, . in the case of cumulative preferred stock, all dividend periods terminating on or before the date of payment of full cumulative dividends, or . in the case of noncumulative preferred stock, the immediately preceding dividend period. When dividends are not paid in full upon any series of preferred stock, and any other preferred stock ranking equally as to dividends with that series of preferred stock, all dividends declared upon shares of that series of preferred stock and any other preferred stock ranking equally as to dividends will be declared pro rata so that the amount of dividends declared per share on that series of preferred stock and any other preferred stock ranking equally as to dividends will in all cases bear to each other the same ratio that accrued dividends per share on the shares of that series of preferred stock and the other preferred stock bear to each other. In the case of noncumulative preferred stock, any accrued dividends described in the immediately preceding paragraph will not include any cumulation in respect of unpaid dividends for prior dividend periods. Except as provided in the immediately preceding paragraph, unless full dividends on all outstanding shares of any series of preferred stock have been declared and paid, . in the case of a series of cumulative preferred stock, for all past dividend periods, or . in the case of noncumulative preferred stock, for the immediately preceding dividend period, then: . ML&Co. may not declare dividends or pay or set aside for payment or other distribution on any of its capital stock ranking junior to or equally with that series of preferred stock as to dividends or upon liquidation, other than dividends or distributions paid in shares of, or options, warrants or rights to subscribe for or purchase shares of, the common stock of ML&Co. or other capital stock of ML&Co. ranking junior to that series of preferred stock as to dividends and upon liquidation, and . other than in connection with the distribution or trading of any of its capital stock, ML&Co. may not redeem, purchase or otherwise acquire any of its capital stock ranking junior to or equally with that series of preferred stock as to dividends or upon liquidation, for any consideration or any moneys paid to or made available for a sinking fund for the redemption of any shares of any of its capital stock, except by conversion or exchange for capital stock of ML&Co. ranking junior to that series of preferred stock as to dividends and upon liquidation. 21 Unless otherwise specified in the applicable prospectus supplement, the amount of dividends payable for any period shorter than a full dividend period shall be computed on the basis of twelve 30-day months, a 360-day year and the actual number of days elapsed in any period of less than one month. As of the date of this prospectus, subsidiaries of ML&Co. have issued $2.673 billion of perpetual Trust Originated Preferred Securities SM ("TOPrS"). In connection with the issuance of the TOPrS, ML&Co. has agreed, among other things, that if full distributions on the TOPrS have not been paid or set apart for payment or if ML&Co. is in default of their related guarantee obligations, ML&Co., with certain exceptions, will not declare or pay dividends, make distributions with respect to, or redeem, purchase or acquire, or make a liquidation payment with respect to any of its capital stock, including the preferred stock. Liquidation Preference Upon any voluntary or involuntary liquidation, dissolution or winding up of ML&Co., the holders of the preferred stock will have preference and priority over the common stock of ML&Co. and any other class of stock of ML&Co. ranking junior to the preferred stock upon liquidation, dissolution or winding up, for payments out of or distributions of the assets of ML&Co. or proceeds from any liquidation, whether from capital or surplus, of the amount per share set forth in the applicable prospectus supplement plus all accrued and unpaid dividends, whether or not earned or declared, to the date of final distribution to such holders. After any liquidating payment, the holders of preferred stock will be entitled to no other payments. If, in the case of any liquidation, dissolution or winding up of ML&Co., the assets of ML&Co. or the proceeds from any liquidation should be insufficient to make the full liquidation payment in the amount per share set forth in the applicable prospectus supplement relating to a series of preferred stock, plus all accrued and unpaid dividends on that preferred stock, and liquidating payments on any other preferred stock ranking as to liquidation, dissolution or winding up equally with that preferred stock, then any assets and proceeds will be distributed among the holders of the preferred stock and any other preferred stock ratably in accordance with the respective amounts which would be payable on those shares of preferred stock and any other preferred stock if all amounts payable were paid in full. In the case of noncumulative preferred stock, accrued and unpaid dividends will not include cumulation of unpaid dividends from prior dividend periods. A consolidation or merger of ML&Co. with one or more corporations will not be deemed to be a liquidation, dissolution or winding up, voluntary or involuntary, of ML&Co. Redemption If specified in the prospectus supplement relating to a series of preferred stock being offered, ML&Co. may, at its option, at any time or from time to time on not less than 30 nor more than 60 days notice, redeem that series of preferred stock in whole or in part at the redemption prices and on the dates set forth in the applicable prospectus supplement. If less than all outstanding shares of a series of preferred stock are to be redeemed, the selection of the shares to be redeemed shall be determined by lot or pro rata as may be determined by the Board of Directors of ML&Co. or a duly authorized committee of the Board of Directors to be equitable. From and after the redemption date, unless ML&Co. is in default in providing for the payment of the redemption price, dividends shall cease to accrue on the shares of that series of preferred stock called for redemption and all rights of the holders shall cease, other than the right to receive the redemption price. Voting Rights Unless otherwise described in the applicable prospectus supplement, holders of the preferred stock will have no voting rights except as set forth below or as otherwise required by law. SM Service mark of Merrill Lynch & Co., Inc. 22 Whenever dividends payable on the preferred stock are in arrears for a number of dividend periods, whether or not consecutive, which in the aggregate is equivalent to six calendar quarters, the holders of outstanding shares of the preferred stock, voting as a class with holders of shares of all other series of preferred stock ranking equally with the preferred stock either as to dividends or the distribution of assets upon liquidation, dissolution or winding up and upon which like voting rights have been conferred and are exercisable, will be entitled to vote for the election of two additional directors on the terms set forth below. These voting rights will continue, in the case of any series of cumulative preferred stock, until all past dividends accumulated on shares of cumulative preferred stock are paid in full and, in the case of noncumulative preferred stock, until all dividends on shares of noncumulative preferred stock are paid in full for at least one calendar year. Upon payment in full of these dividends, the voting rights will terminate except as expressly provided by law. These voting rights are subject to re- vesting in the event of each and every subsequent default in the payment of dividends. Holders of all series of preferred stock which are granted these voting rights and which rank equally with the preferred stock will vote as a class, and, unless otherwise specified in the applicable prospectus supplement, each holder of shares of the preferred stock will have one vote for each share of stock held and each other series will have the number of votes, if any, for each share of stock held as may be granted to them. In the event that the holders of shares of the preferred stock are entitled to vote as described in this paragraph, the Board of Directors of ML&Co. will be increased by two directors, and the holders of the preferred stock will have the exclusive right as members of that class, as outlined above, to elect two directors at the next annual meeting of stockholders. Upon termination of the right of the holders of the preferred stock to vote for directors as discussed in the preceding paragraph, the term of office of all directors then in office elected by those holders will terminate immediately. Whenever the term of office of the directors elected by those holders ends and the related special voting rights expire, the number of directors will automatically be decreased to the number of directors as would otherwise prevail. So long as any shares of preferred stock remain outstanding, ML&Co. shall not, without the affirmative vote or consent of the holders of at least two- thirds of the shares of the preferred stock outstanding at the time, voting as a class with all other series of preferred stock ranking equally with the preferred stock either as to dividends or the distribution of assets upon liquidation, dissolution or winding up and upon which like voting rights have been conferred and are exercisable, given in person or by proxy, either in writing or at a meeting: . authorize, create or issue, or increase the authorized or issued amount of, any class or series of stock ranking senior to the preferred stock with respect to payment of dividends or the distribution of assets upon liquidation, dissolution or winding up of ML&Co.; or . amend, alter or repeal, whether by merger, consolidation or otherwise, the provisions of ML&Co.'s restated certificate of incorporation or the certificate of designations of the preferred stock so as to materially and adversely affect any right, preference, privilege or voting power of the preferred stock or the holders of the preferred stock; provided, however, that any increase in the amount of authorized preferred stock or the creation and issuance, or an increase in the authorized or issued amount, of other series of preferred stock, or any increase in the amount of authorized shares of preferred stock, in each case ranking equally with or junior to the preferred stock with respect to the payment of dividends and the distribution of assets upon liquidation, dissolution or winding of ML&Co. up will not be deemed to materially and adversely affect these rights, preferences, privileges or voting powers. The foregoing voting provisions will not apply if all outstanding shares of preferred stock have been redeemed or sufficient funds have been deposited in trust to effect such a redemption which is scheduled to be consummated within three months after the time that such rights would otherwise be exercisable. 23 Conversion or Exchange Rights The prospectus supplement relating to a series of preferred stock that is convertible or exchangeable will state the terms on which shares of that series are convertible or exchangeable into common stock, another series of preferred stock or debt securities. Outstanding Preferred Stock At March 31, 2000, there were 42,500 shares of 9% Preferred Stock represented by 17,000,000 depositary shares and one Special Voting Share outstanding. 9% Preferred Stock The 9% Preferred Stock has preference over ML&Co.'s common stock and the Series A junior preferred stock issuable under the Rights Plan described under "Description of Common Stock" with respect to the payment of dividends and the distribution of assets in the event of liquidation, dissolution or winding up of ML&Co. Holders of the 9% Preferred Stock do not have any preemptive rights to subscribe for any additional securities which may be issued by ML&Co. Dividends on the 9% Preferred Stock are cumulative and payable quarterly at the rate per annum of 9% of the $10,000 liquidation preference per share. Holders of the 9% Preferred Stock have no voting rights except as set forth above under "--Voting Rights" above. In the event of any voluntary or involuntary liquidation, dissolution or winding up of ML&Co., the holders of outstanding shares of 9% Preferred Stock are entitled to receive out of assets of ML&Co. available for distribution to stockholders a distribution of $10,000 per share, plus accumulated and unpaid dividends, if any. The 9% Preferred Stock is not redeemable before December 30, 2004. On and after that date, the 9% Preferred Stock is redeemable at the option of ML&Co., in whole at any time or from time to time in part, upon not less than 30 nor more than 60 days notice, at a redemption price of $10,000 per share, plus accumulated and unpaid dividends, if any. Special Voting Share In connection with the acquisition of Midland Walwyn Inc. by ML&Co. in August 1998, ML&Co. issued a single share of preferred stock with special voting rights (the "Special Voting Share"), under the terms of a Voting and Exchange Trust Agreement entered into by Merrill Lynch & Co., Canada Ltd. ("ML Canada"), ML&Co. and Montreal Trust Company of Canada, as trustee (the "Voting Trust Agreement"). The Special Voting Share possesses a number of votes equal to the number of exchangeable shares of ML Canada (the "Exchangeable Shares") issued and outstanding from time to time that are not owned by ML&Co. or its affiliates, which votes may be exercised for the election of directors and on all other matters submitted to a vote of ML&Co.'s stockholders. The holders of ML&Co.'s common stock and the holder of the Special Voting Share vote together as a class on all matters. See "Description of Common Stock--Voting Rights". The Special Voting Share was issued to the trustee under the Voting Trust Agreement. The holder of the Special Voting Share is not entitled to receive dividends, and, in the event of any liquidation, dissolution or winding up of ML&Co., will receive an amount equal to the par value of the Special Voting Share. When the Special Voting Share has no votes attached to it because there are no Exchangeable Shares outstanding not owned by ML&Co. or any of its affiliates, the Special Voting Share will cease to have any rights. DESCRIPTION OF DEPOSITARY SHARES ML&Co. may issue depositary receipts evidencing depositary shares, each of which will represent a fraction of a share of preferred stock. ML&Co. will deposit shares of preferred stock of each class or series represented by depositary shares under deposit agreements to be entered into among ML&Co., a bank or trust company, as depositary, and the holders from time to time of the depositary receipts. A copy of the form of deposit agreement, including the form of certificates representing the depositary receipts, is filed as an exhibit to the registration statement of which this prospectus is a part. The following summaries of the material 24 provisions of the deposit agreements and the depositary receipt certificates are not complete, are subject to, and are qualified in their entirety by reference to, all the provisions of the deposit agreement and the depositary receipt certificates, respectively, including the definitions of terms. Terms of the Depositary Shares Depositary receipts issued under the applicable deposit agreement will evidence the depositary shares. Immediately following the issuance and delivery of the preferred stock by ML&Co. to the depositary, ML&Co. will cause the depositary to issue, on behalf of ML&Co., the depositary receipts. Subject to the terms of the applicable deposit agreement, each holder of a depositary receipt will be entitled, in proportion to the fraction of a share of preferred stock represented by the applicable depositary shares, to all the rights and preferences of the preferred stock being represented, including dividend, voting, conversion, redemption and liquidation rights, all as will be set forth in the prospectus supplement relating to the depositary shares being offered. The depositary shares will have the dividend, liquidation, redemption, voting and conversion or exchange rights set forth below unless otherwise specified in the applicable prospectus supplement. The applicable prospectus supplement will describe the terms of the specific issue of the depositary shares being offered, the deposit agreement relating to the depositary shares and the depositary receipts evidencing the depositary shares, including the following: . the designation, stated value and liquidation preference of the depositary shares and the number of shares offered; . the offering price or prices; . the dividend rate or rates, or method of calculation, the dividend periods, the dates on which dividends will be payable and whether dividends are cumulative or noncumulative and, if cumulative, the dates from which dividends will begin to cumulate; . any redemption or sinking fund provisions; . any conversion or exchange provisions; . any material risk factors relating to the depositary shares; . the identity of the depositary; and . any other terms of the depositary shares which are not inconsistent with the provisions of the deposit agreement. Book-Entry Procedures Except as may otherwise be provided in the applicable prospectus supplement, the depositary shares will be evidenced by global depositary receipts, registered in the name of a depositary or its nominee. In that case, beneficial owners will not be entitled to receive depositary receipts evidencing their depositary shares unless the depositary is unwilling or unable to continue as depositary or ML&Co. decides to have the depositary shares represented by separate depositary receipts. A beneficial owner's interest in depositary shares will be recorded on or through the records of the brokerage firm or other entity that maintains the beneficial owner's account. In turn, the total number of depositary shares held by an individual brokerage firm for its clients will be maintained on the records of the depositary in the name of the brokerage firm or its agent. Transfer of ownership of depositary shares will be effected only through the selling beneficial owner's brokerage firm. Dividends and Other Distributions The depositary will distribute all cash dividends or other cash distributions received in respect of the preferred stock to the record holders of depositary receipts in proportion to the number of depositary shares owned by those holders, subject to the obligations of holders to file proofs, certificates and other information and to pay certain charges and expenses to the depositary. 25 In the event of a distribution in respect of the preferred stock other than in cash, the depositary will distribute property it receives to the record holders of the depositary shares, subject to certain obligations of holders to file proofs, certificates and other information and to pay certain charges and expenses to the depositary, unless the depositary, after consultation with ML&Co., determines that it is not feasible to make the distribution, in which case the depositary may, with the approval of ML&Co., sell any property and distribute the net proceeds from the sale to the holders. Withdrawal of Stock Unless the related depositary shares have been previously called for redemption, upon surrender of the depositary receipts at the corporate trust office of the depositary, the holder of the depositary shares will be entitled to delivery, at the corporate trust office of the depositary to or upon his or her order, of the number of whole shares of the preferred stock and any money or other property represented by the depositary shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares. In no event will the depositary deliver fractional shares of preferred stock upon surrender of depositary receipts. Redemption of Depositary Shares Whenever ML&Co. redeems shares of preferred stock held by the depositary, the depositary will redeem as of the same redemption date the number of depositary shares representing shares of the preferred stock so redeemed, provided ML&Co. has paid in full to the depositary the redemption price of the preferred stock to be redeemed plus an amount equal to any accumulated and unpaid dividends on the preferred stock to the date fixed for redemption. The redemption price per depositary share will be equal to the redemption price and any other amounts per share payable with respect to the preferred stock multiplied by the fraction of a share of preferred stock represented by one depositary share. If less than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by the lot or pro rata as may be determined by the depositary. After the date fixed for redemption, depositary shares called for redemption will no longer be deemed to be outstanding and all rights of the holders of depositary shares called for redemption will cease, except the right to receive any moneys payable upon redemption and any money or other property to which the holders of the depositary shares were entitled upon redemption upon surrender to the depositary of the depositary receipts evidencing the depositary shares. Voting the Preferred Stock Upon receipt of notice of any meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts relating to that preferred stock. The record date for the depositary receipts relating to the preferred stock will be the same date as the record date for the preferred stock. Each record holder of the depositary shares on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of preferred stock represented by that holder's depositary shares. The depositary will endeavor, insofar as practicable, to vote the amount of preferred stock represented by the depositary shares in accordance with those instructions, and ML&Co. will agree to take all reasonable action which may be deemed necessary by the depositary in order to enable the depositary to do so. The depositary will not vote any shares of preferred stock except to the extent it receives specific instructions from the holders of depositary shares representing that number of shares of preferred stock. 26 Exchange of Preferred Stock Whenever ML&Co. exchanges all of the shares of a series of preferred stock held by the depositary for debt securities, common stock or other shares of preferred stock, the depositary will exchange as of the same exchange date the number of depositary shares representing all of the shares of the preferred stock so exchanged for debt securities, common stock or other shares of preferred stock, provided ML&Co. has issued and deposited with the depositary, debt securities, common stock or other shares of preferred stock, as applicable, for all of the shares of the preferred stock to be exchanged. The exchange rate per depositary share will be equal to the exchange rate per share of preferred stock multiplied by the fraction of a share of preferred stock represented by one depositary share, plus all money and other property, if any, represented by those depositary shares, including all amounts paid by ML&Co. in respect of dividends which on the exchange date have accumulated on the shares of preferred stock to be so exchanged and have not already been paid. Conversion of Preferred Stock The depositary shares are not convertible or exchangeable into common stock or any other securities or property of ML&Co. Nevertheless, if so specified in the applicable prospectus supplement, each depositary receipt may be surrendered by its holder to the depositary with written instructions to the depositary to instruct ML&Co. to cause conversion or exchange of the preferred stock represented by the depositary shares evidenced by that depositary receipt into whole shares of common stock, other shares of preferred stock or debt securities of ML&Co. ML&Co. has agreed that upon the receipt of any instructions to convert or exchange any depositary shares and the payment of any fees or other amounts applicable to any conversion or exchange, it will convert or exchange the depositary shares using the same procedures as those provided for delivery of preferred stock to effect conversions or exchange. If the depositary shares represented by a depositary receipt are converted in part only, a new depositary receipt or receipts will be issued for any depositary shares not converted or exchanged. Amendment and Termination of the Deposit Agreement The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may at any time be amended by agreement between ML&Co. and the depositary. However, any amendment that materially and adversely alters the rights of the holders of depositary receipts will not be effective unless it has been approved by the holders of at least a majority of the depositary shares then outstanding. No amendment to the form of depositary receipt or any provision of the deposit agreement relating to or affecting rights to receive dividends or distributions or voting, redemption or conversion rights will be effective unless approved by the holders of at least two-thirds of the depositary shares then outstanding. ML&Co. may terminate the deposit agreement at any time upon 60 days prior written notice to the depositary, in which case the depositary will deliver to the record holders, upon surrender of the depositary receipts, the number of whole or fractional shares of preferred stock as is represented by those depositary receipts. The deposit agreement will automatically terminate if: . all outstanding depositary shares have been redeemed, . all shares of preferred stock deposited with the depositary in accordance with the terms of the deposit agreement and all money and other property relating to those shares of preferred stock have been withdrawn in accordance with the terms of the deposit agreement, or . there has been a final distribution in respect of the preferred stock in connection with any liquidation, dissolution or winding up of ML&Co. and the distribution has been distributed to the holders of depositary receipts. Charges of Depositary ML&Co. will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. ML&Co. will pay the fees and expenses of the depositary in connection with 27 the performance of its duties under the deposit agreement. Holders of depositary receipts will pay transfer and other taxes and governmental charges and any other charges that are expressly provided in the deposit agreement to be for their accounts. The depositary may refuse to effect any transfer of a depositary receipt or any withdrawals of preferred stock evidenced by a depositary receipt until all taxes and charges with respect to the depositary receipt or preferred stock are paid by their holders. Resignation and Removal of Depositary The depositary may resign at any time by delivering to ML&Co. notice of its election to do so, and ML&Co. may remove the depositary at any time. Any resignation or removal of the depositary will take effect upon ML&Co.'s appointment of a successor depositary, which must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000. Notices The depositary will forward to holders of depositary receipts all reports and communications received from ML&Co. and the depositary and which ML&Co. is required to furnish to holders of the related underlying preferred stock. The depositary will also, promptly after its receipt, transmit to the holders of depositary receipts, copies of all notices and reports required by law, the rules of any national securities exchange or ML&Co.'s restated certificate of incorporation to be furnished to the record holders of depositary receipts. Limitation of Liability Neither the depositary nor ML&Co. will assume any obligation or be subject to any liability under the deposit agreement to holders of depositary receipts other than for negligence, willful misconduct or bad faith. The depositary will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or any shares of preferred stock unless it is furnished with satisfactory indemnification. ML&Co. and the depositary may rely on written advice of counsel or accountants, or information provided by persons presenting shares of preferred stock for deposit, holders of depositary receipts or other persons believed to be competent and on documents believed to be genuine. Neither the depositary nor ML&Co. will be liable if it is prevented from or delayed, by law, by provision of ML&Co.'s restated certificate of incorporation or any circumstances beyond its control, in performing its obligations under the deposit agreement. DESCRIPTION OF PREFERRED STOCK WARRANTS ML&Co. may issue warrants for the purchase of preferred stock ("Preferred Stock Warrants"). Each series of Preferred Stock Warrants is to be issued under a preferred stock warrant agreement to be entered into between ML&Co. and a bank or trust company, as preferred stock warrant agent, as described in the applicable prospectus supplement relating to the Preferred Stock Warrants being offered. A copy of the form of preferred stock warrant agreement, including the form of warrant certificates representing the Preferred Stock Warrants, is filed as an exhibit to the registration statement of which this prospectus is a part. The following summaries of the material provisions of the preferred stock warrant agreement and preferred stock warrant certificates are not complete and are subject to and are qualified in their entirety by reference to, all the provisions of the preferred stock warrant agreement and the preferred stock warrant certificates, respectively, including the definitions of terms. Terms of the Preferred Stock Warrants The applicable prospectus supplement will describe the terms of the specific issue of Preferred Stock Warrants being offered, the preferred stock warrant agreement relating to the Preferred Stock Warrants and the preferred stock warrant certificates representing the Preferred Stock Warrants, including the following: 28 . the offering price or prices; . designation, aggregate number and terms of the series of preferred stock that may be purchased upon exercise of the Preferred Stock Warrants and the minimum number of Preferred Stock Warrants that are exercisable; . any designation and terms of the securities with which the Preferred Stock Warrants are being offered and the number of Preferred Stock Warrants being offered with each Security; . any date on and after which the Preferred Stock Warrants and the related securities will be transferable separately; . the number and stated values of the series of preferred stock that may be purchased upon exercise of each Preferred Stock Warrant and the price at which the shares of preferred stock of that series may be purchased upon exercise, and events or conditions under which the number of shares that may be purchased may be adjusted; . the date on which the right to exercise the Preferred Stock Warrants will begin and the date on which the right to exercise will expire; . any circumstances that will cause the Preferred Stock Warrants to be deemed to be automatically exercised; . any material risk factors relating to the Preferred Stock Warrants; . the identity of the preferred stock warrant agent; and . any other terms of the Preferred Stock Warrants which are not inconsistent with the provisions of the preferred stock warrant agreement. Holders may exchange preferred stock warrant certificates for new preferred stock warrant certificates of different denominations, may, if in registered form, present for registration of transfer, and exercise the Preferred Stock Warrants at the corporate trust office of the preferred stock warrant agent or any other office indicated in the applicable prospectus supplement. Before the exercise of any Preferred Stock Warrant, a holder will not have the rights of a holder of shares of the preferred stock that may be purchased upon exercise of the Preferred Stock Warrant, including the right to receive payment of dividends, if any, on the underlying preferred stock or the right to vote the underlying preferred stock. Prospective purchasers of Preferred Stock Warrants should be aware that special U.S. Federal income tax, accounting and other considerations may be applicable to instruments such as Preferred Stock Warrants. The prospectus supplement relating to any issue of Preferred Stock Warrants will describe these considerations. Book-Entry Procedures Except as may otherwise be provided in the applicable prospectus supplement, the Preferred Stock Warrants will be issued in the form of global preferred stock warrant certificates, registered in the name of a depositary or its nominee. In that case, beneficial owners will not be entitled to receive definitive certificates representing Preferred Stock Warrants unless the depositary is unwilling or unable to continue as depositary, specified events of bankruptcy or insolvency occur with respect to ML&Co. or ML&Co. decides to have the Preferred Stock Warrants represented by definitive certificates. A beneficial owner's interest in a Preferred Stock Warrant will be recorded on or through the records of the brokerage firm or other entity that maintains the beneficial owner's account. In turn, the total number of Preferred Stock Warrants held by an individual brokerage firm for its clients will be maintained on the records of the depositary in the name of the brokerage firm or its agent. Transfer of ownership of any Preferred Stock Warrant will be effected only through the selling beneficial owner's brokerage firm. 29 Exercise of Preferred Stock Warrants Each Preferred Stock Warrant will entitle its holder to purchase a number of shares of preferred stock at the exercise price described in the applicable prospectus supplement. After the close of business on the date the right to exercise the Preferred Stock Warrants expires, or any later date if extended by ML&Co., unexercised Preferred Stock Warrants will become void. Holders may exercise the Preferred Stock Warrants in the manner set forth in the applicable prospectus supplement. Upon receipt of payment and a properly completed and duly executed preferred stock warrant certificate at the corporate trust office of the preferred stock warrant agent or any other office indicated in the applicable prospectus supplement, ML&Co. will, as soon as practicable, issue and deliver the shares of preferred stock purchased upon exercise. If less than all of the Preferred Stock Warrants represented by any preferred stock warrant certificate are exercised, ML&Co. will issue a new preferred stock warrant certificate for the remaining number of Preferred Stock Warrants. Listing ML&Co. may list an issue of Preferred Stock Warrants on a national securities exchange. Any listing will be specified in the applicable prospectus supplement. Modifications ML&Co. and the preferred stock warrant agent may amend any preferred stock warrant agreement and the terms of the related Preferred Stock Warrants, without the consent of the holders of the Preferred Stock Warrants, for the purpose of curing any ambiguity, or of curing, correcting or supplementing any defective or inconsistent provision, or in any other manner which ML&Co. may deem necessary or desirable and which will not materially and adversely affect the interests of the preferred stock warrantholders. ML&Co. and the preferred stock warrant agent also may amend any preferred stock warrant agreement and the terms of the related Preferred Stock Warrants, with the consent of the holders of not less than a majority in number of the then outstanding unexercised Preferred Stock Warrants affected by the amendment. However, without the consent of each of the preferred stock warrantholders affected, no amendment will be effective that: . shortens the period of time during which the Preferred Stock Warrants may be exercised; . otherwise materially and adversely affects the exercise rights of the preferred stock warrantholders; or . reduces the number of outstanding Preferred Stock Warrants the consent of whose holders is required to approve an amendment of the preferred stock warrant agreement or the terms of the related Preferred Stock Warrants. Enforceability of Rights by Preferred Stock Warrantholders Any preferred stock warrantholder may, without the consent of the related preferred stock warrant agent, enforce by appropriate legal action, in and of its own behalf, its right to exercise its Preferred Stock Warrants. DESCRIPTION OF COMMON STOCK The following description sets forth the general terms of common stock which ML&Co. may issue. The description set forth below and in any prospectus supplement is not complete, is subject to, and is qualified in its entirety by reference to, ML&Co's restated certificate of incorporation which is filed as an exhibit to the registration statement of which this prospectus is a part. 30 Terms of the Common Stock Under ML&Co.'s restated certificate of incorporation, ML&Co. is authorized to issue up to 1,000,000,000 shares of common stock, par value $1.33 1/3 per share. As of May 5, 2000, there were 385,241,585 shares of common stock and 2,634,634 Exchangeable Shares outstanding. The Exchangeable Shares are exchangeable at any time into common stock on a one-for-one basis and entitle holders to dividend, voting and other rights equivalent to common stock. The common stock is traded on the New York Stock Exchange under the symbol "MER" and also on the Chicago Stock Exchange, the Pacific Exchange, the Paris Bourse, the London Stock Exchange and the Tokyo Stock Exchange. The common stock has the dividend, voting, liquidation and preemptive rights set forth below unless otherwise specified in the prospectus supplement being used to offer the common stock. The applicable prospectus supplement will describe the terms of the common stock including, where applicable, the following: . the number of shares to be offered; . the offering price or prices; . to the extent permitted by applicable law, whether the common stock will be issued in certificated or book-entry form; . information with respect to any book-entry procedures; and . any additional terms of the common stock which are not inconsistent with the provisions of ML&Co.'s restated certificate of incorporation. The common stock will be, when issued against payment therefor, fully paid and nonassessable. Holders of the common stock will have no preemptive rights to subscribe for any additional securities which may be issued by ML&Co. The rights of holders of common stock will be subject to, and may be adversely affected by, the rights of holders of any preferred stock that has been issued and may be issued in the future. As of March 31, 2000, 17,000,000 depositary shares, each representing a one-four-hundredth interest in a share of 9% Preferred Stock, and one Special Voting Share were outstanding. See "Description of Preferred Stock--Outstanding Preferred Stock" for a description of that preferred stock . The Board of Directors of ML&Co. may issue additional shares of preferred stock to obtain additional financing, in connection with acquisitions, to officers, directors and employees of ML&Co. and its subsidiaries pursuant to benefit plans or otherwise and for other proper corporate purposes. ML&Co. is the principal transfer agent for the common stock. Because ML&Co. is a holding company, its rights, and the rights of holders of its securities, including the holders of common stock, to participate in the distribution of assets of any subsidiary of ML&Co. upon the subsidiary's liquidation or recapitalization will be subject to the prior claims of the subsidiary's creditors and preferred stockholders, except to the extent ML&Co. may itself be a creditor with recognized claims against the subsidiary or a holder of preferred stock of the subsidiary. Dividends ML&Co. may pay dividends on the common stock out of funds legally available for the payment of dividends as, if and when declared by the Board of Directors of ML&Co. or a duly authorized committee of the Board of Directors. As of the date of this prospectus, subsidiaries of ML&Co. have issued $2.673 billion of perpetual TOPrS. In connection with the issuance of the TOPrS, ML&Co. has agreed, among other things, that if full distributions on the TOPrS have not been paid or set apart for payment or ML&Co. is in default of its related guarantee obligations, ML&Co., with certain exceptions, will not declare or pay dividends, make distributions 31 with respect to, or redeem, purchase or acquire, or make a liquidation payment with respect to any of its capital stock, including the common stock. Liquidation Rights Upon any voluntary or involuntary liquidation, dissolution, or winding up of ML&Co., the holders of its common stock will be entitled to receive, after payment of all of its debts, liabilities and of all sums to which holders of any preferred stock may be entitled, all of the remaining assets of ML&Co. Voting Rights Except as described under "Description of Preferred Stock--Outstanding Preferred Stock", the holders of the common stock currently possess exclusive voting rights in ML&Co. The Board of Directors of ML&Co. may, however, give voting power to any preferred stock which may be issued in the future. Each holder of common stock is entitled to one vote per share with respect to all matters. There is no cumulative voting in the election of directors. Actions requiring approval of stockholders generally require approval by a majority vote of outstanding shares. The Board of Directors of ML&Co. is currently comprised of 13 directors, divided into three classes, the precise number of members to be fixed from time to time by the Board of Directors. The directors of the class elected at each annual election hold office for a term of three years, with the term of each class expiring at successive annual meetings of stockholders. Rights to Purchase Series A Junior Preferred Stock Under the Amended and Restated Rights Agreement, adopted on December 2, 1997 (the "Rights Agreement"), preferred purchase rights were distributed to holders of common stock. The preferred purchase rights are attached to each outstanding share of common stock and will attach to all subsequently issued shares, including common stock that may be offered by ML&Co. pursuant to an applicable prospectus supplement. The preferred purchase rights entitle the holder to purchase fractions of a share ("Units") of Series A junior preferred stock at an exercise price of $300 per Unit, subject to adjustment from time to time as provided in the Rights Agreement. The exercise price and the number of Units issuable are subject to adjustment to prevent dilution. The preferred purchase rights will separate from the common stock ten days following the earlier of: . an announcement of an acquisition by a person or group of 15% or more of the outstanding common stock of ML&Co.; or . the commencement of a tender or exchange offer for 15% or more of the shares of common stock of ML&Co. outstanding. If, after the preferred purchase rights have separated from the common stock, . ML&Co. is the surviving corporation in a merger with an acquiring party, . a person becomes the beneficial owner of 15% or more of the common stock, . an acquiring party engages in one or more defined "self-dealing" transactions, or . an event occurs which results in such acquiring party's ownership interest being increased by more than 1%, then, in each case, each holder of a preferred purchase right will have the right to purchase Units of Series A junior preferred stock having a value equal to two times the exercise price of the preferred purchase right. In addition, preferred purchase rights held by or transferred in certain circumstances by an acquiring party may immediately become void. 32 In the event that, at any time, . ML&Co. is acquired in a merger or other business combination transaction and ML&Co. is not the surviving corporation, . any person consolidates or merges with ML&Co. and all or part of ML&Co.'s common stock is converted or exchanged for securities, cash or property of any other person or . 50% or more of ML&Co.'s assets or earning power is sold or transferred, each holder of a right will have the right to purchase common stock of the acquiring party having a value equal to two times the exercise price of the preferred purchase right. The preferred purchase rights expire on December 2, 2007. The preferred purchase rights are redeemable at the option of a majority of the independent directors of ML&Co. at $.01 per right at any time until the tenth day following an announcement of the acquisition of 15% or more of the common stock. The foregoing provisions of the Rights Agreement may have the effect of delaying, deferring or preventing a change in control of ML&Co. The certificate of designations of the Series A junior preferred stock provides that the holders of Units of the Series A junior preferred stock will be entitled to receive quarterly dividends in an amount to be determined in accordance with the formula set forth in the certificate of designations. These dividend rights are cumulative. The Series A junior preferred stock rank junior in right of payment of dividends to the 9% Preferred Stock and to all other preferred stock issued by ML&Co., unless the terms of any other preferred stock provide otherwise. The holders of Units of the Series A junior preferred stock will have one vote per Unit on all matters submitted to the stockholders of ML&Co., subject to adjustment. If at any time dividends on any Units of the Series A junior preferred stock are in arrears for a number of periods, whether or not consecutive, which in the aggregate is equivalent to six calendar quarters, then during that period of default, the holders of all Units, voting separately as a class, will have the right to elect two directors to the Board of Directors of ML&Co. Additionally, whenever quarterly dividends or other dividends or distributions payable on the Series A junior preferred stock are in arrears, ML&Co. shall not, among other things, declare or pay dividends on or make any other distributions on, or redeem or purchase or otherwise acquire for consideration any shares or capital stock of ML&Co. which ranks junior in right of payment to the Series A junior preferred stock, including the common stock. In the event of any voluntary or involuntary liquidation, dissolution or winding up of ML&Co., the holders of outstanding Units of the Series A junior preferred stock will be entitled to receive a distribution in an amount to be determined in accordance with the formula set forth in the certificate of designations before the payment of any distribution to the holders of common stock.

DESCRIPTION OF COMMON STOCK WARRANTS ML&Co. may issue warrants for the purchase of common stock ("Common Stock Warrants"). Each series of Common Stock Warrants will be issued under a common stock warrant agreement to be entered into between ML&Co. and a bank or trust company, as common stock warrant agent, all as set forth in the applicable prospectus supplement. A copy of the form of common stock warrant agreement, including the form of warrant certificates representing the Common Stock Warrants, reflecting the provisions to be included in the common stock warrant agreements that will be entered into with respect to particular offerings of Common Stock Warrants, is filed as an exhibit to the registration statement of which this prospectus is a part. The following summaries of the material provisions of the common stock warrant agreement and common stock warrant certificates are not complete, are subject to, and are qualified in their entirety by reference to, all of the provisions of the common stock warrant agreement and the common stock warrant certificates, including the definitions of terms. Terms of the Common Stock Warrants The applicable prospectus supplement will describe the terms of the Common Stock Warrants being offered, the common stock warrant agreement relating to the Common Stock Warrants and the common stock warrant certificates, including the following: . the offering price or prices; . the aggregate number of shares of common stock that may be purchased upon exercise of the Common Stock Warrants and minimum number of Common Stock Warrants that are exercisable; . the number of securities, if any, with which the Common Stock Warrants are being offered and the number of the Common Stock Warrants being offered with each security; . the date on and after which the Common Stock Warrants and the related securities, if any, will be transferable separately; . the number of shares of common stock purchasable upon exercise of each Common Stock Warrant, the price at which the common stock may be purchased, and events or conditions under which the number of shares purchasable may be adjusted; . the date on which the right to exercise the Common Stock Warrants will begin and the date on which the right to exercise will expire; . the circumstances, if any, which will cause the Common Stock Warrants to be deemed to be automatically exercised; . any material risk factors relating to the Common Stock Warrants; . the identity of the common stock warrant agent; and . any other terms of the Common Stock Warrants which are not inconsistent with the provisions of the common stock warrant agreement. Holders may exchange common stock warrant certificates for new common stock warrant certificates of different denominations, if in registered form, may present for registration of transfer, and may exercise the Common Stock Warrants, at the corporate trust office of the common stock warrant agent or any other office indicated in the applicable prospectus supplement. Before the exercise of any Common Stock Warrants to 34 purchase common stock, holders of the Common Stock Warrants will not have any rights of holders of common stock purchasable upon exercise of the Common Stock Warrants, including the right to receive payments of dividends, if any, on the common stock purchasable upon any exercise or the right to vote the underlying common stock. Prospective purchasers of Common Stock Warrants should be aware that special U.S. Federal income tax, accounting and other considerations may be applicable to instruments such as Common Stock Warrants. The prospectus supplement relating to any issue of Common Stock Warrants will describe these considerations. Book-Entry Procedures Except as may otherwise be provided in the applicable prospectus supplement, the Common Stock Warrants will be issued in the form of global common stock warrant certificates, registered in the name of a depositary or its nominee. In that case, beneficial owners will not be entitled to receive definitive certificates representing Common Stock Warrants unless the depositary is unwilling or unable to continue as depositary, certain specified events of bankruptcy or insolvency occur with respect to ML&Co. or ML&Co. decides to have the Common Stock Warrants represented by definitive certificates. A beneficial owner's interest in a Common Stock Warrant will be recorded on or through the records of the brokerage firm or other entity that maintains a beneficial owner's account. In turn, the total number of Common Stock Warrants held by an individual brokerage firm for its clients will be maintained on the records of the depositary in the name of the brokerage firm or its agent. Transfer of ownership of any Common Stock Warrant will be effected only through the selling beneficial owner's brokerage firm. Exercise of Common Stock Warrants Each Common Stock Warrant will entitle its holder to purchase a specific number of shares of common stock at the exercise price described in the applicable prospectus supplement. After the close of business on the date the right to exercise the Common Stock Warrants expires, or any later date if extended by ML&Co., unexercised Common Stock Warrants will become void. Common Stock Warrants may be exercised as set forth in the applicable prospectus supplement. Upon receipt of payment and a properly completed and duly executed common stock warrant certificate at the corporate trust office of the common stock warrant agent or any other office indicated in the applicable prospectus supplement, ML&Co. will, as soon as practicable, issue and deliver the shares of common stock purchased upon exercise. If less than all of the Common Stock Warrants represented by any common stock warrant certificate are exercised, a new common stock warrant certificate will be issued for the remaining Common Stock Warrants. Listing ML&Co. may list an issue of Common Stock Warrants on a national securities exchange. Any listing will be specified in the applicable prospectus supplement. Modifications ML&Co. and the common stock warrant agent may amend any common stock warrant agreement and the terms of the related Common Stock Warrants, without the consent of the holders of the Common Stock Warrants, for the purpose of curing any ambiguity, or of curing, correcting or supplementing any defective or inconsistent provision, or in any other manner which ML&Co. may deem necessary or desirable and which will not materially and adversely affect the interests of the common stock warrantholders. ML&Co. and the common stock warrant agent also may amend any common stock warrant agreement and the terms of the related Common Stock Warrants, with the consent of the holders of not less than a majority in 35 number of the then outstanding unexercised Common Stock Warrants affected by amendment. However, without the consent of each of the common stock warrantholders affected, no amendment will be effective that: . shortens the period of time during which the Common Stock Warrants may be exercised; . otherwise materially and adversely affects the exercise rights of the common stock warrantholders; or . reduces the number of outstanding Common Stock Warrants the consent of whose holders is required to approve an amendment of the common stock warrant agreement or the terms of the related Common Stock Warrants. Enforceability of Rights by common stock warrantholders Any common stock warrantholder may, without the consent of the related common stock warrant agent, enforce by appropriate legal action, in and for its own behalf, its right to exercise its Common Stock Warrant. PLAN OF DISTRIBUTION ML&Co. may sell securities: . to the public through MLPF&S, or through a group of underwriters managed or co-managed by, one or more underwriters, including MLPF&S, . through MLPF&S as agent, or . directly to purchasers.

EXPERTS The consolidated financial statements and the related financial statement schedule incorporated in this prospectus by reference from the Annual Report on Form 10-K of Merrill Lynch & Co., Inc. and subsidiaries for the year ended December 31, 1999 have been audited by Deloitte & Touche LLP, independent auditors, as stated in their reports (each of which express an unqualified opinion and which report on the consolidated financial statements includes an explanatory paragraph for the change in accounting method in 1998 for certain internal-use software development costs to conform with Statement of Position 98-1), which are incorporated herein by reference, and have been so incorporated in reliance upon the reports of such firm given upon their authority as experts in accounting and auditing. With respect to unaudited interim financial information for the periods included in the Quarterly Reports on Form 10-Q which are incorporated herein by reference, Deloitte & Touche LLP have applied limited procedures in accordance with professional standards for a review of such information. However, as stated in their report included in such Quarterly Reports on Form 10-Q and incorporated by reference herein, they did not audit and they do not express an opinion on such interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Deloitte & Touche LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933, as amended, for their reports on unaudited interim financial information because such report is not a "report" or a "part" of the Registration Statement prepared or certified by an accountant within the meaning of Sections 7 and 11 of the Securities Act of 1933, as amended. 38 - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- [LOGO] $17,939,515,000 Merrill Lynch & Co., Inc.
