CUSIP:	$

MERRILL LYNCH & CO., INC., a corporation duly organized and existing under the laws of the State of Delaware (herein called the “Company”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum of FOUR HUNDRED AND TWENTY-FIVE MILLION DOLLARS ($425,000,000) on September 15, 2026 (the “Stated Maturity”) and to pay interest on said principal sum quarterly in arrears on the 15^th of March, June, September and December of each year, commencing December 15, 2006 (each such date, an “Interest Payment Date”). For any Interest Accrual Period (defined below), interest will accrue at a rate per annum equal to Three-Month U.S. Dollar LIBOR, reset quarterly, plus 76 basis points, from and including the first day of an Interest Accrual Period to but excluding the last day of the Interest Accrual Period or the date on which the principal is paid or duly made available for payment; provided, however, that the rate of interest in effect from and including September 12, 2006 to but excluding the first Interest Payment Date shall be 6.15097%. The amount of interest paid for any period will be computed on the basis of a 360-day year and the actual number of days elapsed during such quarterly Interest Accrual Period. “Interest Accrual Period” means the period from and including each scheduled Interest Payment Date to but excluding the next succeeding scheduled Interest Payment Date; provided, however, that the initial Interest Accrual Period shall be from and including September 12, 2006 to but excluding the first Interest Payment Date. In the event that an Interest Payment Date, other than an Interest Payment Date falling on the Stated Maturity, falls on a day that is not a Business Day, the payment due on such Interest Payment Date shall be paid on the next succeeding Business Day (and no interest will accrue on the amount payable from such scheduled payment date to the next succeeding Business Day) unless such Business Day falls in the next succeeding calendar month, in which case the Interest Payment Date shall be the Business Day immediately preceding the scheduled Interest Payment Date, in each case with the same force and effect as if made on the date the payment was originally payable. If the Stated Maturity falls on a day that is not a Business Day, the payment of principal and interest due on the Stated Maturity shall be paid on the next succeeding Business Day (and no interest will accrue on the amount payable from such scheduled payment date to the next succeeding Business Day) with the same force and effect as if made on the date the payment was originally payable. A “Business Day” shall mean any day other

than a Saturday or Sunday that is neither a legal holiday nor a day on which banking institutions in The City of New York are authorized or required by law, regulation or executive order to close. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date shall, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities, as defined in the Indenture) is registered at the close of business on the Regular Record Date for such interest installment, which shall be the close of business on the fifteenth calendar day immediately preceding such scheduled Interest Payment Date. Any such interest installment not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

“Three-Month U.S. Dollar LIBOR,” with respect to an Interest Accrual Period, means:

(i) the rate (expressed as a percentage per annum) for deposits in U.S. dollars for a three month period, commencing on the related Interest Reset Date for such Interest Accrual Period, that appears on Moneyline Telerate Page 3750, as displayed on page “BBAM” (British Bankers Association Official BBA LIBOR Fixings) in the Bloomberg Professional Service (or any other service that may replace Moneyline Telerate, Inc. on page BBAM or any other page that may replace page BBAM on the Bloomberg Professional Service or a successor service, in each case, for the purpose of displaying London interbank offered rates of major banks), as of 11:00 A.M., London time, on the applicable Interest Determination Date; or

(ii) if no rate appears on the particular Interest Determination Date on Moneyline Telerate Page 3750 or any successor service or page as may replace Moneyline Telerate Page 3750, Three-Month U.S. Dollar LIBOR shall be the rate calculated by the Trustee as the arithmetic mean of at least two offered quotations obtained by the Trustee after requesting the principal London offices of each of four major reference banks, which may include our affiliates, in the London interbank market to provide the trustee with its offered quotation for deposits in U.S. dollars for a three month period, commencing on the related Interest Reset Date, to prime banks in the London interbank market at approximately 11:00 A.M., London time, on that Interest Determination Date and in a principal amount that is representative for a single transaction in U.S. dollars in that market at that time; or

(iii) if fewer than two offered quotations referred to in (ii) above are provided as requested, Three-Month U.S. Dollar LIBOR shall be the rate calculated by the Trustee as the arithmetic mean of the rates quoted at approximately 11:00 A.M., in The City of New York, on the particular Interest Determination Date by three major banks, which may include our affiliates, in The City of New York selected by the Trustee for loans in U.S. dollars to leading European banks, for a period of 3 months and in a principal amount that is representative for a single transaction in U.S. dollars in that market at that time; or

(iv) if the banks selected by the Trustee are not quoting as mentioned in (iii) above, Three-Month U.S. Dollar LIBOR for that Interest Accrual Period shall equal Three-Month U.S. Dollar LIBOR for the immediately preceding Interest Accrual Period.

An “Interest Determination Date” for an Interest Accrual Period shall be the second London Business Day prior to the Interest Reset Date for that Interest Accrual Period.

An “Interest Reset Date” shall occur on the 15^th of March, June, September and December of each year, commencing December 15, 2006; provided, however, that if any scheduled Interest Reset Date falls on a day that is not a Business Day, the Interest Reset Date shall be postponed to the next succeeding Business Day unless such Business Day falls in the next succeeding calendar month, in which case the Interest Reset Date shall be the Business Day immediately preceding the scheduled Interest Reset Date.

A “London Business Day” means a day other than a Saturday or Sunday on which dealings in deposits in U.S. dollars are transacted, or with respect to any future date are expected to be transacted, in the London interbank market.

Payment of the principal of and interest on this Security will be made at the office or agency of the Company maintained for that purpose in New York, New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

The Company, or an affiliate of the Company, will act as calculation agent with respect to the Notes.

The indebtedness evidenced by this Security is, to the extent provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness, and this Security is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee his attorney-in-fact for any and all such purposes. Each Holder hereof, by his acceptance hereof, waives all notice of the acceptance of the subordination provisions contained herein and in the indenture of each holder of Senior Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such holder upon said provisions.

Reference is hereby made to the further provisions of the Indenture summarized on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

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

IN WITNESS WHEREOF, Merrill Lynch & Co., Inc. has caused this instrument to be duly executed under its corporate seal.

The Securities are issuable only in registered form without coupons in minimum denominations of $100,000.00 and integral multiples of $1,000.00 in excess thereof.
