MEDIUM-TERM NOTE,

SERIES C

Merrill Lynch Extendible Monthly Securities

(the “Notes”)

     MERRILL LYNCH & CO., INC., a Delaware corporation (“Issuer” or the “Company,” which terms
include 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 $[•] ([•]
DOLLARS) on September 15, 2010 (the “Final Stated Maturity Date”) (or such lesser amount as shall
not have been earlier exchanged for other notes pursuant to the terms hereof), and to pay interest
on the principal amount hereof outstanding from time to time, at a rate per annum determined in
accordance with the provisions hereof, until the principal hereof is paid or duly made available
for payment.

     The “Original Issue Date” is August 23, 2005.

     The “Initial Stated Maturity Date” of this Note is September 15, 2006, or if such date is not
a Business Day (as defined herein), the Business Day immediately preceding such date.

     To exercise the option to extend the Note in whole or in part, this Note and the duly
completed form entitled “Option to Extend Maturity” below must be received, by the Trustee at
its office at 111 Sanders Creek Parkway, Syracuse, New York 13057, Attention: Corporate Trust
Operations or such address which the Company shall from time to time notify the Holders of the
Notes (any such office being the “Corporate Trust Office”), no later than the close of business,
New York City time, on the last Business Day during the Notice Period (as defined herein) for the
applicable Election Date (as defined herein). Exercise of such extension option by the Holder
hereof shall be revocable during such Notice Period until 12:00 noon, New York City time, on the
last Business Day in the Notice Period relating to the applicable Election Date, upon which time
such notice will become irrevocable.

 

 

EXHIBIT A-1

     If on any Election Date a Holder does not make an election to extend the maturity date of all
or any portion of the principal amount of this Note, the principal amount of this Note for which
such election was not made shall become due and payable on the Initial Stated Maturity Date or any
Subsequent Stated Maturity Date (as defined herein), if applicable, to which the maturity date of
such principal amount shall have previously been extended. The principal amount of this Note for
which such election is not exercised shall be represented by a new Merrill Lynch Extendible Monthly
Security (a “New Note”), issued on the last Business Day of the applicable Notice Period in the
Form of Exhibit A hereto. The New Note so issued shall have the same terms as this Note, except
that it shall not be extendible, shall have a separate CUSIP number and its stated maturity date
shall be the date that is 366 calendar days from and including such Election Date, or if such
366th calendar day is not a Business Day, the immediately preceding Business Day. The
failure to elect to extend the maturity date of all or any portion of this Note shall be
irrevocable and shall be binding upon any subsequent Holder of such notes.

     To exercise the option to extend the maturity date of all or of any portion of this Note
having a principal amount of $1,000 or any multiple of $1,000 in excess thereof the Holder must
deliver notice to the Trustee, as described above, during the applicable Notice Period for that
Election Date. The new maturity date for the portion of this Note that has been so extended shall
be the 366th calendar day from, and including, the 15th calendar day of the
month immediately succeeding such election, provided that if such 366th calendar day is
not a Business Day, the new maturity date shall be the immediately preceding Business Day (a
“Subsequent Stated Maturity Date”). A Subsequent Stated Maturity Date cannot occur on any date
after the Final Stated Maturity Date.

     To the extent that the Trustee has not received a duly completed “Option to Extend Maturity”
form within the applicable Election Period in accordance with the terms of this Note as to all or
part of the principal amount of this Note, the Trustee shall (a) issue a new Note in the form of
Exhibit A hereto representing such principal amount and (b) reduce or cause to be reduced the
outstanding principal amount of this Note by such amount.

     “Election Date” means the 15th calendar day of each month from September 2005 to
August 2009 inclusive, whether or not such day is a Business Day.

     The “Notice Period” for each Election Date shall begin on the fifth scheduled Business Day
prior to but not including the Election Date and end on the Election Date; however, if that
Election Date is not a Business Day, the Notice Period will be extended to the following
Business Day.

     This Note may not be redeemed at the option of the Company in whole or in part.

     The Company shall pay interest on the 15th calendar day of each month, commencing
September 15, 2005 and on the Final Stated Maturity Date (each an “Interest Payment Date”); (the
date of such Final Stated Maturity Date and the date on which principal or an installment of
principal is due and payable by declaration of acceleration pursuant to the Indenture being
referred to hereinafter as a “Maturity” with respect to principal payable on such date);
provided, however, that if an Interest Payment Date (other than an Interest Payment
Date at Maturity) would fall on a day that is not a Business Day, such Interest Payment Date shall
be postponed to the next succeeding day that is a Business Day. The “Regular Record Date” shall be
the date 15 calendar days (whether or not a Business Day) prior to the applicable Interest Payment
Date. Interest on this Note shall accrue from and including the Original Issue Date, at the rates
determined from time to time as specified herein, until the principal hereof has been paid or made
available for payment. The interest 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
Note is registered at the close of business on the Regular Record Date for such Interest Payment
Date. Any such interest which is payable, but not punctually paid or duly provided for on any
Interest Payment Date (herein called “Defaulted Interest”), shall forthwith cease to be payable to
the registered Holder on such Regular Record Date, and may be paid to the Person in whose name this
Note 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 the Holder of this
Note not less than 10 days prior to such Special Record Date, or may be paid at any time in any
other lawful manner, all as more fully provided in the Indenture.

     The “Interest Rate” borne by this Note shall be LIBOR (as defined below) plus the applicable
Spread (as defined below).

EXHIBIT A-1

     Commencing on the first Interest Reset Date, the rate at which interest on this Note is
payable shall be reset as of each Interest Reset Date. An “Interest Reset Date” means the
15th calendar day of each month, commencing on September 15, 2005.

     Except as provided above, the interest rate in effect on each day shall be (a) if such day is
an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as
defined below) immediately preceding such Interest Reset Date or (b) if such day is not an Interest
Reset Date, the interest rate determined as of the Interest Determination Date immediately
preceding the immediately preceding Interest Reset Date. LIBOR shall be determined in accordance
with the applicable provision below. If any Interest Reset Date would otherwise be a day that is
not a Business Day, that Interest Reset Date shall be postponed to the next succeeding day that is
a Business Day.

     Interest payable on this Note on any Interest Payment Date shall be 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 Original Issue Date specified above, if no
interest has been paid), to but excluding the related Interest Payment Date or Maturity. Accrued
interest hereon shall be an amount calculated by multiplying the face amount hereof by an accrued
interest factor. The accrued interest factor shall be computed by adding the interest factor
calculated for each day in the period for which accrued interest is being calculated. The interest
factor for each such day shall be computed by dividing the interest rate applicable to each day by
360.

     “Interest Determination Date” means the second London Banking Day (as defined below) preceding
each Interest Reset Date.

     All percentages resulting from any calculation on this Note shall 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 shall be rounded to the nearest cent
with one-half cent being rounded upward.

     As used herein, “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 and such day is also a London Banking Day (as
hereinafter defined).

     As used herein, “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.

     “LIBOR” as determined by the Calculation Agent (as defined below) means:

	 	(1)	 	The rate for deposits in the LIBOR Currency, as defined below, having an index
maturity of one month commencing on the related Interest Reset Date, that appears on
the LIBOR Page, as defined below, as of 11:00 A.M., London time, on the particular
Interest Determination Date, or
	 
	 	(2)	 	if no rate appears on the particular Interest Determination Date on the LIBOR
Page as specified above, the rate calculated by the Calculation Agent as the arithmetic
mean of at least two offered quotations obtained by the Calculation Agent after
requesting the principal London offices of each of four major reference banks, which
may include affiliates of the agent, in the London interbank market to provide the
Calculation Agent with its offered quotation for deposits in the LIBOR Currency for the
period of the index maturity of one month, 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 principal amount that is
representative for single transaction in the LIBOR Currency in that market at that
time, or
	 
	 	(3)	 	if fewer than two offered quotations referred to in clause (2) are provided as
requested, the rate calculated by the Calculation Agent 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 affiliates of the
Calculation Agent, in The City of New York selected by the Calculation Agent for loans
in the LIBOR Currency to leading European banks, having the index maturity of one month
and in principal amount that is representative for single

	 	 	 	transaction in the LIBOR
Currency in that market at that time, or
	 
	 	(4)	 	if the banks selected by the Calculation Agent are not quoting as mentioned in
clause (3), LIBOR in effect on the particular Interest Determination Date.

     “LIBOR Currency” means United States dollars.

     “LIBOR Page” means the display on Reuters (or any successor service) on page LIBOR01 or any
page as may replace such page on that service for the purpose of displaying the London interbank
rates of major banks for the LIBOR Currency.

     The “Spread” applicable to this Note shall equal (i) minus .02%, for Interest Reset Dates
occurring from the Original Issue Date to and including August 2006, (ii) plus .01%, for Interest
Reset Dates occurring from and including September 2006 to and

including August 2009 and (v) plus .18 % for Interest Reset Dates occurring from and including

     The Calculation Agent shall calculate the interest rate hereon in accordance with the
foregoing on or before each Calculation Date. The Company hereby covenants for the benefit of the
Holder hereof, to the extent permitted by applicable law, not to claim voluntarily the benefits of
any laws concerning usurious rates of interest against such Holder.

     Merrill Lynch, Pierce, Fenner & Smith Incorporated shall be the “Calculation Agent”. At the
request of the Holder hereof, the Calculation Agent shall provide to the Holder hereof the interest
rate hereon then in effect and, if determined, the interest rate which shall become effective as of
the next Interest Reset Date with respect to this Note.

     Payment of the principal of and interest on this Note shall be made at the Office or Agency of
the Company maintained by the Company for such purpose in the Borough of Manhattan, The City of 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.

     Unless the certificate of authentication hereon has been executed by or on behalf of The Bank
of New York, the Trustee with respect to the Notes under the Indenture, or its successor
thereunder, by the manual signature of one of its authorized officers, this Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

Securities are issued and to be issued under an indenture (the “Indenture”) dated as of April 1,

integral multiples thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes as

shall be registered in such name or names as the Depository shall instruct the Trustee. If
definitive Notes are so delivered, the Company may make such changes to the form of this Note as
are necessary or appropriate to allow for the issuance of such definitive Notes.

with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of the Holders of the
Securities of each series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of 66 2/3% in aggregate original public offering price or

MEDIUM-TERM NOTE,

Merrill Lynch Extendible Monthly Securities

(Election not made) (the “Note”)

     MERRILL LYNCH & CO., INC., a Delaware corporation (“Issuer” or the “Company,” which terms
include 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 specified above on
the Stated Maturity specified above, and to pay interest thereon, at a rate per annum determined in
accordance with the provisions hereof, until the principal hereof is paid or duly made available
for payment.

     This Note may not be redeemed at the option of the Company in whole or in part.

     The Company shall pay interest on the 15th calendar day of each month, commencing
September 15, 2005 and on the Stated Maturity (each an “Interest Payment Date”); (such Stated
Maturity and the date on which principal or an installment of principal is due and payable by
declaration of acceleration pursuant to the Indenture being referred to hereinafter as a “Maturity”
with respect to principal payable on such date); provided, however, that if an
Interest Payment Date (other than an Interest Payment Date at Maturity) would fall on a day that is
not a Business Day (as defined below), such Interest Payment Date shall be postponed to the next
succeeding day that is a Business Day. The “Regular Record Date” shall be the date 15
calendar days (whether or not a Business Day) prior to the applicable Interest Payment Date.
Interest on this Note shall accrue from and including the Original Issue Date, at the rates
determined from time to time as specified herein, until the principal hereof has been paid or made
available for payment. The interest 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
Note is registered at the close of business on the Regular Record Date for such Interest Payment
Date. Any such interest which is payable, but not punctually paid or duly provided for on any
Interest Payment Date (herein called “Defaulted Interest”), shall forthwith cease to be

EXHIBIT A-1

payable to
the registered Holder on such Regular Record Date, and may be paid to the Person in whose name this
Note 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 the Holder of this
Note not less than 10 days prior to such Special Record Date, or may be paid at any time in any
other lawful manner, all as more fully provided in the Indenture.

     The “Interest Rate” borne by this Note shall be LIBOR (as defined below) plus the applicable
Spread (as defined below).

     Commencing on the first Interest Reset Date, the rate at which interest on this Note is
payable shall be reset as of each Interest Reset Date. An “Interest Reset Date” means the
15th calendar day of each month, commencing on September 15, 2005.

     Except as provided above, the interest rate in effect on each day shall be (a) if such day is
an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as
defined below) immediately preceding such Interest Reset Date or (b) if such day is not an Interest
Reset Date, the interest rate determined as of the Interest Determination Date immediately
preceding the immediately preceding Interest Reset Date. LIBOR shall be determined in accordance
with the applicable provision below. If any Interest Reset Date would otherwise be a day that is
not a Business Day, that Interest Reset Date shall be postponed to the next succeeding day that is
a Business Day.

     Interest payable on this Note on any Interest Payment Date shall be the amount of interest
accrued from and including the immediately preceding Interest Payment Date in respect of which
interest has been paid, including any interest paid on the Merrill Lynch Extendible Monthly
Securities issued on August 23, 2005 (or from and including the Original Issue Date specified
above, if no interest has been paid), to but excluding the related Interest Payment Date or
Maturity. Accrued interest hereon shall be an amount calculated by multiplying the face amount
hereof by an accrued interest factor. The accrued interest factor shall be computed by adding the
interest factor calculated for each day in the period for which accrued interest is being
calculated. The interest factor for each such day shall be computed by dividing the interest rate
applicable to each day by 360.

     “Interest Determination Date” means the second London Banking Day (as defined below) preceding
each Interest Reset Date.

     All percentages resulting from any calculation on this Note shall 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 shall be rounded to
the nearest cent with one-half cent being rounded upward.

     As used herein, “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 and such day is also a London Banking Day (as
hereinafter defined).

     As used herein, “London Banking Day” means a day on which commercial banks are open for
business, including dealings in the LIBOR Currency, in London.

     “LIBOR” as determined by the Calculation Agent (as defined below) means:

	 	(1)	 	The rate for deposits in the LIBOR Currency, as defined below, having an index
maturity of one month commencing on the related Interest Reset Date, that appears on
the LIBOR Page, as defined below, as of 11:00 A.M., London time, on the particular
Interest Determination Date, or
	 
	 	(2)	 	if no rate appears on the particular Interest Determination Date on the LIBOR
Page as specified above, the rate calculated by the Calculation Agent as the arithmetic
mean of at least two offered quotations obtained by the Calculation Agent after
requesting the principal London offices of each of four major reference banks, which
may include affiliates of the agent, in the London interbank market to provide the
Calculation Agent with its offered quotation for deposits in the LIBOR

A-2 

 

EXHIBIT A-1

	 	 	 	Currency for the
period of the index maturity of one month, 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 principal amount that is
representative for single transaction in the LIBOR Currency in that market at that
time, or
	 
	 	(3)	 	if fewer than two offered quotations referred to in clause (2) are provided as
requested, the rate calculated by the Calculation Agent 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 affiliates of the
agent, in The City of New York selected by the Calculation Agent for loans in the LIBOR
Currency to leading European banks, having the index maturity of one month and in
principal amount that is representative for single transaction in the LIBOR Currency in
that market at that time, or
	 
	 	(4)	 	if the banks selected by the Calculation Agent are not quoting as mentioned in
clause (3), LIBOR in effect on the particular Interest Determination Date.

     “LIBOR Currency” means United States dollars.

     “LIBOR Page” means the display on Reuters (or any successor service) on page LIBOR01 or any
page as may replace such page on that service for the purpose of displaying the London interbank
rates of major banks for the LIBOR Currency.

     The “Spread” applicable to this Note shall equal (i) minus .02%, for Interest Reset Dates
occurring from the Original Issue Date to and including August 2006, (ii) plus .01%, for Interest
Reset Dates occurring from and including September 2006 to and
including August 2007, (iii) plus .14 %, for Interest Reset Dates occurring from and including September 2007 to and including August
2008, (iv) plus .16 %, for Interest Reset Dates occurring from and including September 2008 to and
including August 2009 and (v) plus .18 %, for Interest Reset Dates occurring from and including
September 2009 to and including August 2010.

     The Calculation Agent shall calculate the interest rate hereon in accordance with the
foregoing on or before each Calculation Date. The Company hereby covenants for the benefit of the
Holder hereof, to the extent permitted by applicable law, not to claim voluntarily the benefits of
any laws concerning usurious rates of interest against such Holder.

     Merrill Lynch, Pierce, Fenner & Smith Incorporated shall be the “Calculation Agent”. At the
request of the Holder hereof, the Calculation Agent shall provide to the Holder hereof the interest
rate hereon then in effect and, if determined, the interest rate which shall become effective as of

MEDIUM-TERM NOTE,

SERIES C

Merrill Lynch Extendible Monthly Securities

(Election not made) (the “Note”)

     MERRILL LYNCH & CO., INC., a Delaware corporation (“Issuer” or the “Company,” which terms
include 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 specified above on
the Stated Maturity specified above, and to pay interest thereon, at a rate per annum determined in
accordance with the provisions hereof, until the principal hereof is paid or duly made available
for payment.

     This Note may not be redeemed at the option of the Company in whole or in part.

     The Company shall pay interest on the 15th calendar day of each month, commencing
September 15, 2005 and on the Stated Maturity (each an “Interest Payment Date”); (such Stated
Maturity and the date on which principal or an installment of principal is due and payable by
declaration of acceleration pursuant to the Indenture being referred to hereinafter as a “Maturity”
with respect to principal payable on such date); provided, however, that if an
Interest Payment Date (other than an Interest Payment Date at Maturity) would fall on a day that is
not a Business Day (as defined below), such Interest Payment Date shall be postponed to the next
succeeding day that is a Business Day. The “Regular Record Date” shall be the date 15 calendar
days (whether or not a Business Day) prior to the applicable Interest Payment Date.
Interest on this Note shall accrue from and including the Original Issue Date, at the rates
determined from time to time as specified herein, until the principal hereof has been paid or made
available for payment. The interest 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
Note is registered at the close of business on the Regular Record Date for such Interest Payment
Date. Any such interest which is payable, but not punctually paid or duly provided for on any
Interest Payment Date (herein called “Defaulted Interest”), shall forthwith cease to be payable to
the registered Holder on such Regular Record Date, and may be paid to the Person in whose name this

 

 

EXHIBIT A-2

Note 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 the Holder of this
Note not less than 10 days prior to such Special Record Date, or may be paid at any time in any
other lawful manner, all as more fully provided in the Indenture.

     The “Interest Rate” borne by this Note shall be LIBOR (as defined below) plus the applicable
Spread (as defined below).

     Commencing on the first Interest Reset Date, the rate at which interest on this Note is
payable shall be reset as of each Interest Reset Date. An “Interest Reset Date” means the
15th calendar day of each month, commencing on September 15, 2005.

     Except as provided above, the interest rate in effect on each day shall be (a) if such day is
an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as
defined below) immediately preceding such Interest Reset Date or (b) if such day is not an Interest
Reset Date, the interest rate determined as of the Interest Determination Date immediately
preceding the immediately preceding Interest Reset Date. LIBOR shall be determined in accordance
with the applicable provision below. If any Interest Reset Date would otherwise be a day that is
not a Business Day, that Interest Reset Date shall be postponed to the next succeeding day that is
a Business Day.

     Interest payable on this Note on any Interest Payment Date shall be the amount of interest
accrued from and including the immediately preceding Interest Payment Date in respect of which
interest has been paid, including any interest paid on the Merrill Lynch Extendible Monthly
Securities issued on August 23, 2005 (or from and including the Original Issue Date specified
above, if no interest has been paid), to but excluding the related Interest Payment Date or
Maturity. Accrued interest hereon shall be an amount calculated by multiplying the face amount
hereof by an accrued interest factor. The accrued interest factor shall be computed by adding the
interest factor calculated for each day in the period for which accrued interest is being
calculated. The interest factor for each such day shall be computed by dividing the interest rate
applicable to each day by 360.

     “Interest Determination Date” means the second London Banking Day (as defined below) preceding
each Interest Reset Date.

     All percentages resulting from any calculation on this Note shall 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 shall be rounded to the nearest cent
with one-half cent being rounded upward.

     As used herein, “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 and such day is also a London Banking Day (as
hereinafter defined).

business, including dealings in the LIBOR Currency, in London.

     “LIBOR” as determined by the Calculation Agent (as defined below) means:

	 	(1)	 	The rate for deposits in the LIBOR Currency, as defined below, having an index
maturity of one month commencing on the related Interest Reset Date, that appears on
the LIBOR Page, as defined below, as of 11:00 A.M., London time, on the particular
Interest Determination Date, or
	 
	 	(2)	 	if no rate appears on the particular Interest Determination Date on the LIBOR
Page as specified above, the rate calculated by the Calculation Agent as the arithmetic
mean of at least two offered quotations obtained by the Calculation Agent after
requesting the principal London offices of each of four major reference banks, which
may include affiliates of the agent, in the London interbank market to provide the
Calculation Agent with its offered quotation for deposits in the LIBOR Currency for the
period of the index maturity of one month, commencing on the related Interest Reset
Date, to prime banks in the London interbank market at approximately 11:00 A.M., London

 

 

EXHIBIT A-2

	 	 	 	time, on that Interest Determination Date and in principal amount that is
representative for single transaction in the LIBOR Currency in that market at that
time, or
	 
	 	(3)	 	if fewer than two offered quotations referred to in clause (2) are provided as
requested, the rate calculated by the Calculation Agent 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 affiliates of the
agent, in The City of New York selected by the Calculation Agent for loans in the LIBOR
Currency to leading European banks, having the index maturity of one month and in
principal amount that is representative for single transaction in the LIBOR Currency in
that market at that time, or
	 
	 	(4)	 	if the banks selected by the Calculation Agent are not quoting as mentioned in
clause (3), LIBOR in effect on the particular Interest Determination Date.

     “LIBOR Currency” means United States dollars.

     “LIBOR Page” means the display on Reuters (or any successor service) on page LIBOR01 or any
page as may replace such page on that service for the purpose of displaying the London interbank
rates of major banks for the LIBOR Currency.

     The “Spread” applicable to this Note shall equal (i) minus .02%, for Interest Reset Dates
occurring from the Original Issue Date to and including August 2006, (ii) plus .01%, for Interest
Reset Dates occurring from and including September 2006 to and
including August 2007, (iii) plus .14 %, for Interest Reset Dates occurring from and including September 2007 to and including August
2008, (iv) plus .16 %, for Interest Reset Dates occurring from and including September 2008 to and
including August 2009 and (v) plus .18 %, for Interest Reset Dates occurring from and including
September 2009 to and including August 2010.

     The Calculation Agent shall calculate the interest rate hereon in accordance with the
foregoing on or before each Calculation Date. The Company hereby covenants for the benefit of the
Holder hereof, to the extent permitted by applicable law, not to claim voluntarily the benefits of
any laws concerning usurious rates of interest against such Holder.

     Merrill Lynch, Pierce, Fenner & Smith Incorporated shall be the “Calculation Agent”. At the
request of the Holder hereof, the Calculation Agent shall provide to the Holder hereof the interest
rate hereon then in effect and, if determined, the interest rate which shall become effective as of
the next Interest Reset Date with respect to this Note.

     Payment of the principal of and interest on this Note shall be made at the Office or Agency of
the Company maintained by the Company for such purpose in the Borough of Manhattan, The City of 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.

     Unless the certificate of authentication hereon has been executed by or on behalf of The Bank
of New York, the Trustee with respect to the Notes under the Indenture, or its successor
thereunder, by the manual signature of one of its authorized officers, this Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

     This Note is one of a duly authorized issue of Securities (hereinafter called the
“Securities”) of the Company designated as its Medium-Term Notes, Series C (the “Notes”). The
Securities are issued and to be issued under an indenture (the “Indenture”) dated as of April 1,
1983, between the Company and The Bank of New York (herein called the “Trustee”, which term
includes any successor Trustee under the Indenture), as amended and restated, to which Indenture

rights thereunder of the Company, the Trustee and the Holders of the Notes and the terms upon which
the Notes are to be authenticated and delivered.

integral multiples thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the Notes are

 

 

EXHIBIT A-2

exchangeable for a like aggregate principal amount of Notes as
requested by the Holder surrendering the same. If (x) the Depository is at any time unwilling or
unable to continue as depository and a successor depository is not appointed by the Company within
60 days, (y) the Company executes and delivers to the Trustee a Company Order to the effect that
this Note shall be exchangeable or (z) an Event of Default has occurred and is continuing with
respect to the Notes, this Note shall be exchangeable for Notes in definitive form of like tenor
and of an equal aggregate principal amount, in authorized denominations. Such definitive Notes
shall be registered in such name or names as the Depository shall instruct the Trustee. If
definitive Notes are so delivered, the Company may make such changes to the form of this Note as
are necessary or appropriate to allow for the issuance of such definitive Notes.

     This Note is not subject to any sinking fund.

     If an Event of Default (as defined in the Indenture) with respect to the Notes shall occur and
be continuing, the principal of all the Notes may be declared due and payable in the manner and
with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of the Holders of the
Securities of each series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of 66 2/3% in aggregate original public offering price or
principal amount, as the case may be, of the Securities at any time
Outstanding, as defined in the Indenture, of each series affected thereby. Holders of
specified percentages in aggregate original public offering price or principal amount, as the case
may be, of the Securities of each series at the time Outstanding, on behalf of the Holders of all

exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon

principal of and interest on this Note at the time, place and rate, and in the coin or currency,

Operations or such address which the Company shall from time to time notify the Holders of the
Notes (any such office being the “Corporate Trust Office”), no later than the close of business,
New York City time, on the last Business Day during the Notice Period (as defined herein) for
the applicable Election Date (as defined herein). Exercise of such extension option by the Holder
hereof shall be revocable during each day of such notice period until 12:00 noon, New York City
time, on the last Business Day in the notice period relating to the applicable election date, at
which time such notice will become irrevocable.

 

 

EXHIBIT B-1

     If on any Election Date a Holder does not make an election to extend the maturity date of all
or any portion of the principal amount of this Note, the principal amount of this Note for which
such election was not made shall become due and payable on the Initial Stated Maturity Date or any
Subsequent Stated Maturity Date (as defined herein), if applicable, to which the maturity date of
such principal amount shall have previously been extended. The principal amount of this Note for
which such election is not exercised shall be represented by a new Merrill Lynch Extendible Monthly
Security (a “New Note”), issued on the last Business Day of the applicable Notice Period in the
Form of Exhibit A hereto. The New Note so issued shall have the same terms as this Note, except
that it shall not be extendible, shall have a separate CUSIP number and its stated maturity date
shall be the date that is 366 calendar days from and including such Election Date, or if such
366th calendar day is not a Business Day, the immediately preceding Business Day. The
failure to elect to extend the maturity date of all or any portion of this Note shall be
irrevocable and shall be binding upon any subsequent Holder of such notes.

     To exercise the option to extend the maturity date of all or of any portion of this Note
having a principal amount of $1,000 or any multiple of $1,000 in excess thereof the Holder must
deliver notice to the Trustee, as described above, during the applicable Notice Period for that
Election Date. The new maturity date for the portion of this Note that has been so extended shall
be the 366th calendar day from, and including, the 24th calendar day of the
next succeeding month immediately following such election, provided that if such 366th
calendar day is not a Business Day, the new maturity date shall be the immediately preceding
Business Day (a “Subsequent Stated Maturity Date”). A Subsequent Stated Maturity Date cannot occur
on any date after the Final Stated Maturity Date.

     To the extent that the Trustee has not received a duly completed “Option to Extend Maturity”
form within the applicable Election Period in accordance with the terms of this Note as to all or
part of the principal amount of this Note, the Trustee shall (a) issue a new Note in the form of
Exhibit A hereto representing such principal amount and (b) reduce or cause to be reduced the
outstanding principal amount of this Note by such amount.

     “Election Date” means the 24th calendar day of each month from August 2006 to July
2010 inclusive, whether or not such day is a Business Day.

     The “Notice Period” for each Election Date shall begin on the fifth scheduled Business Day
prior to but not including the Election Date and end on the Election Date; however, if that
Election Date is not a Business Day, the Notice Period will be extended to the following Business
Day.

     This Note may not be redeemed at the option of the Company in whole or in part.

     The Company shall pay interest on the 24th calendar day of each month, commencing
August 24, 2006 and on the Final Stated Maturity Date (each an “Interest Payment Date”); (the
date of such Final Stated Maturity Date and the date on which principal or an installment of
principal is due and payable by declaration of acceleration pursuant to the Indenture being
referred to hereinafter as a “Maturity” with respect to principal payable on such date);
provided, however, that if an Interest Payment Date (other than an Interest Payment
Date at Maturity) would fall on a day that is not a Business Day, such Interest Payment Date shall
be postponed to the next succeeding day that is a Business Day. The “Regular Record Date” shall be
the date 15 calendar days (whether or not a Business Day) prior to the applicable Interest Payment
Date. Interest on this Note shall accrue from and including the Original Issue Date, at the rates
determined from time to time as specified herein, until the principal hereof has been paid or made
available for payment. The interest 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
Note is registered at the close of business on the Regular Record Date for such Interest Payment
Date. Any such interest which is payable, but not punctually paid or duly provided for on any
Interest Payment Date (herein called “Defaulted Interest”), shall forthwith cease to be payable to
the registered Holder on such Regular Record Date, and may be paid to the Person in whose name this
Note 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 the Holder of this
Note not less than 10 days prior to such Special Record Date, or may be paid at any time in any
other lawful manner, all as more fully provided in the Indenture.

     The “Interest Rate” borne by this Note shall be LIBOR (as defined below) plus the applicable
Spread (as defined below); provided that for the period from and including the Original Issue Date
to but excluding the initial Interest Reset Date (as defined below), the Interest Rate shall be a
rate based upon an interpolation of two-week

2

 

EXHIBIT B-1

LIBOR and one-month LIBOR, to be determined two London
Banking Days prior to the Original Issue Date, minus the applicable Spread of .02%.

     Commencing on the first Interest Reset Date, the rate at which interest on this Note is
payable shall be reset as of each Interest Reset Date. An “Interest Reset Date” means the
24th calendar day of each month, commencing on August 24, 2006.

     Except as provided above, the interest rate in effect on each day shall be (a) if such day is
an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as
defined below) immediately preceding such Interest Reset Date or (b) if such day is not an Interest
Reset Date, the interest rate determined as of the Interest Determination Date immediately
preceding the immediately preceding Interest Reset Date. LIBOR shall be determined in accordance
with the applicable provision below. If any Interest Reset Date would otherwise be a day that is
not a Business Day, that Interest Reset Date shall be postponed to the next succeeding day that is
a Business Day.

     Interest payable on this Note on any Interest Payment Date shall be 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 Original Issue Date specified above, if no
interest has been paid), to but excluding the related Interest Payment Date or Maturity. Accrued
interest hereon shall be an amount calculated by multiplying the face amount hereof by an accrued
interest factor. The accrued interest factor shall be computed by adding the interest factor
calculated for each day in the period for which accrued interest is being calculated. The
interest factor for each such day shall be computed by dividing the interest rate applicable
to each day by 360.

     “Interest Determination Date” means the second London Banking Day (as defined below) preceding
each Interest Reset Date.

     All percentages resulting from any calculation on this Note shall 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 shall be rounded to the nearest cent
with one-half cent being rounded upward.

     As used herein, “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 and such day is also a London Banking Day (as
hereinafter defined).

     As used herein, “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.

     “LIBOR” as determined by the Calculation Agent (as defined below) means:

	 	(1)	 	The rate for deposits in the LIBOR Currency, as defined below, having an index
maturity of one month commencing on the related Interest Reset Date, that appears on
the LIBOR Page, as defined below, as of 11:00 A.M., London time, on the particular
Interest Determination Date, or
	 
	 	(2)	 	if no rate appears on the particular Interest Determination Date on the LIBOR
Page as specified above, the rate calculated by the Calculation Agent as the arithmetic
mean of at least two offered quotations obtained by the Calculation Agent after
requesting the principal London offices of each of four major reference banks, which
may include affiliates of the Calculation Agent, in the London interbank market to
provide the Calculation Agent with its offered quotation for deposits in the LIBOR
Currency for the period of the index maturity of one month, 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 principal amount
that is representative for single transaction in the LIBOR Currency in that market at
that time, or
	 
	 	(3)	 	if fewer than two offered quotations referred to in clause (2) are provided as
requested, the rate calculated by the Calculation Agent 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

3

 

EXHIBIT B-1

	 	 	 	major banks, which may include affiliates of the
Calculation Agent, in The City of New York selected by the Calculation Agent for loans
in the LIBOR Currency to leading European banks, having the index maturity of one month
and in principal amount that is representative for single transaction in the LIBOR
Currency in that market at that time, or
	 
	 	(4)	 	if the banks selected by the Calculation Agent are not quoting as mentioned in
clause (3), LIBOR in effect on the particular Interest Determination Date.

     “LIBOR Currency” means United States dollars.

     “LIBOR Page” means the display on Reuters (or any successor service) on page LIBOR01 or any
page as may replace such page on that service for the purpose of displaying the London interbank
rates of major banks for the LIBOR Currency.

     The “Spread” applicable to this Note shall equal (i) minus .02%, for Interest Reset Dates
occurring from the Original Issue Date to but excluding August 2007, (ii) plus .01%, for Interest
Reset Dates occurring in August 2007, (iii) plus .14%, for Interest Reset Dates occurring from and
including September 2007 to but excluding August 2008, (iv) plus .16%, for Interest Reset Dates
occurring from and including August 2008 to but excluding August 2009, (v) plus .18%, for Interest
Reset Dates occurring from and including August 2009 to but
excluding August 2010 and (vi) plus .20%, for Interest Reset Dates occurring from and including August 2010 to but excluding August
2011.

     The Calculation Agent shall calculate the interest rate hereon in accordance with the
foregoing on or before each Interest Determination Date. The Company hereby covenants for the
benefit of the Holder hereof, to the extent permitted by applicable law, not to claim voluntarily
the benefits of any laws concerning usurious rates of interest against such Holder.

     Merrill Lynch, Pierce, Fenner & Smith Incorporated shall be the “Calculation Agent”. At the
request of the Holder hereof, the Calculation Agent shall provide to the Holder hereof the interest
rate hereon then in effect and, if determined, the interest rate which shall become effective as of
the next Interest Reset Date with respect to this Note.

     Payment of the principal of and interest on this Note shall be made at the Office or Agency of
the Company maintained by the Company for such purpose in the Borough of Manhattan, The City of 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.

     Unless the certificate of authentication hereon has been executed by or on behalf of The Bank
of New York, the Trustee with respect to the Notes under the Indenture, or its successor
thereunder, by the manual signature of one of its authorized officers, this Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

     This Note is one of a duly authorized issue of Securities (hereinafter called the
“Securities”) of the Company designated as its Medium-Term Notes, Series C (the “Notes”). The
Securities are issued and to be issued under an indenture (the “Indenture”) dated as of April 1,
1983, between the Company and The Bank of New York, (herein called the “Trustee”, which term
includes any successor Trustee under the Indenture), as amended and restated, to which Indenture
and all indentures supplemental thereto reference is hereby made for a statement of the respective
rights thereunder of the Company, the Trustee and the Holders of the Notes and the terms upon which
the Notes are to be authenticated and delivered.

     The Notes are issuable only in registered form without coupons in denominations of $1,000 and
integral multiples thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes as
requested by the Holder surrendering the same. If (x) the Depository is at any time unwilling or
unable to continue as depository and a successor depository is not appointed by the Company within
60 days, (y) the Company executes and delivers to the Trustee a Company Order to the effect that
this Note shall be exchangeable or (z) an Event of Default has occurred and is continuing with
respect to the Notes, this Note shall be exchangeable for Notes in definitive form of like tenor
and of an equal

EXHIBIT B-1

aggregate principal amount, in authorized denominations. Such definitive Notes
shall be registered in such name or names as the
Depository shall instruct the Trustee. If definitive Notes are so delivered, the Company may
make such changes to the form of this Note as are necessary or appropriate to allow for the
issuance of such definitive Notes.

     This Note is not subject to any sinking fund.

     If an Event of Default (as defined in the Indenture) with respect to the Notes shall occur and
be continuing, the principal of all the Notes may be declared due and payable in the manner and
with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of the Holders of the
Securities of each series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of 66 2/3% in aggregate original public offering price or
principal amount, as the case may be, of the Securities at any time Outstanding, as defined in the
Indenture, of each series affected thereby. Holders of specified percentages in aggregate original
public offering price or principal amount, as the case may be, of the Securities of each series at
the time Outstanding, on behalf of the Holders of all the Securities of each series, are permitted
to waive compliance by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of
this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note
and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the
principal of and interest on this Note at the time, place and rate, and in the coin or currency,
herein prescribed.

     As provided in the Indenture and subject to certain limitations set forth therein and on the
face hereof, the transfer of this Note may be registered on the Security Register of the Company,
upon surrender of this Note for registration of transfer at the office or agency of the Company in
the Borough of Manhattan, The City of New York, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company duly executed by, the Holder hereof or
by his attorney duly authorized in writing, and thereupon one or more new Notes of authorized
denominations and for the same aggregate principal amount, shall be issued to the designated
transferee or transferees.

     No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

     Prior to due presentment of this Note for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name this Note is
registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

     The Indenture and the Notes shall be governed by and construed in accordance with the laws of
the State of New York.

     All terms used in this Note which are defined in the Indenture but not in this Note shall have
the meanings assigned to them in the Indenture.

MEDIUM-TERM NOTE,

SERIES C

Merrill Lynch Extendible Monthly Securities

(Election not made) (the “Note”)

     MERRILL LYNCH & CO., INC., a Delaware corporation (“Issuer” or the “Company,” which terms
include 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 specified above on
the Stated Maturity specified above, and to pay interest thereon, at a rate per annum determined in
accordance with the provisions hereof, until the principal hereof is paid or duly made available
for payment.

     This Note may not be redeemed at the option of the Company in whole or in part.

     The Company shall pay interest on the 24th calendar day of each month, commencing
August 24, 2006 and on the Stated Maturity (each an “Interest Payment Date”); (such Stated Maturity
and the date on which principal or an installment of principal is due and payable by declaration of
acceleration pursuant to the Indenture being referred to hereinafter as a “Maturity” with respect
to principal payable on such date); provided, however, that if an Interest Payment
Date (other than an Interest Payment Date at Maturity) would fall on a day that is not a Business
Day (as defined below), such Interest Payment Date shall be postponed to the next succeeding day
that is a Business Day. The “Regular Record Date” shall be the date 15
calendar days (whether or not a Business Day) prior to the applicable Interest Payment Date.
Interest on this Note shall accrue from and including the Original Issue Date, at the rates
determined from time to time as specified herein, until the principal hereof has been paid or made
available for payment. The interest 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
Note is registered at the close of business on the Regular Record Date for such Interest Payment
Date. Any such interest which is payable, but not punctually paid or duly provided for on any
Interest Payment Date (herein called “Defaulted Interest”), shall forthwith cease to be

 

 

EXHIBIT B-1

payable to
the registered Holder on such Regular Record Date, and may be paid to the Person in whose name this
Note 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 the Holder of this
Note not less than 10 days prior to such Special Record Date, or may be paid at any time in any
other lawful manner, all as more fully provided in the Indenture.

     The “Interest Rate” borne by this Note shall be LIBOR (as defined below) plus the applicable
Spread (as defined below).

     Commencing on the first Interest Reset Date, the rate at which interest on this Note is
payable shall be reset as of each Interest Reset Date. An “Interest Reset Date” means the
24th calendar day of each month, commencing on August 24, 2006.

     Except as provided above, the interest rate in effect on each day shall be (a) if such day is
an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as
defined below) immediately preceding such Interest Reset Date or (b) if such day is not an Interest
Reset Date, the interest rate determined as of the Interest Determination Date immediately
preceding the immediately preceding Interest Reset Date. LIBOR shall be determined in accordance
with the applicable provision below. If any Interest Reset Date would otherwise be a day that is
not a Business Day, that Interest Reset Date shall be postponed to the next succeeding day that is
a Business Day.

     Interest payable on this Note on any Interest Payment Date shall be the amount of interest
accrued from and including the immediately preceding Interest Payment Date in respect of which
interest has been paid, including any interest paid on the Merrill Lynch Extendible Monthly
Securities issued on August 3, 2006 (or from and including the Original Issue Date specified above,
if no interest has been paid), to but excluding the related Interest Payment Date or Maturity.
Accrued interest hereon shall be an amount calculated by multiplying the face amount hereof by an
accrued interest factor. The accrued interest factor shall be computed by adding the interest
factor calculated for each day in the period for which accrued interest is being calculated. The
interest factor for each such day shall be computed by dividing the interest rate applicable to
each day by 360.

     “Interest Determination Date” means the second London Banking Day (as defined below) preceding
each Interest Reset Date.

     All percentages resulting from any calculation on this Note shall 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 shall be rounded to
the nearest cent with one-half cent being rounded upward.

     As used herein, “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 and such day is also a London Banking Day (as
hereinafter defined).

     As used herein, “London Banking Day” means a day on which commercial banks are open for
business, including dealings in the LIBOR Currency, in London.

     “LIBOR” as determined by the Calculation Agent (as defined below) means:

	 	(1)	 	The
rate for deposits in the LIBOR Currency, as defined below, having an index maturity of
one month commencing on the related Interest Reset Date, that appears on the LIBOR
Page, as defined below, as of 11:00 A.M., London time, on the particular Interest
Determination Date, or
	 
	 	(2)	 	if no rate appears on the particular Interest Determination Date on the LIBOR
Page as specified above, the rate calculated by the Calculation Agent as the arithmetic
mean of at least two offered quotations obtained by the Calculation Agent after
requesting the principal London offices of each of four major reference banks, which
may include affiliates of the Calculation Agent, in the London interbank market to
provide the Calculation Agent with its offered quotation for deposits

2

 

EXHIBIT B-1

	 	 	 	in the LIBOR
Currency for the period of the index maturity of one month, 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 principal amount
that is representative for single transaction in the LIBOR Currency in that market at
that time, or
	 
	 	(3)	 	if fewer than two offered quotations referred to in clause (2) are provided as
requested, the rate calculated by the Calculation Agent 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 affiliates of the
Calculation Agent, in The City of New York selected by the Calculation Agent for loans
in the LIBOR Currency to leading European banks, having the index maturity of one month
and in principal amount that is representative for single transaction in the LIBOR
Currency in that market at that time, or
	 
	 	(4)	 	if the banks selected by the Calculation Agent are not quoting as mentioned in
clause (3), LIBOR in effect on the particular Interest Determination Date.

     “LIBOR Currency” means United States dollars.

     “LIBOR Page” means the display on Reuters (or any successor service) on page LIBOR01 or any
page as may replace such page on that service for the purpose of displaying the London interbank
rates of major banks for the LIBOR Currency.

     The “Spread” applicable to this Note shall equal (i) minus .02%, for Interest Reset Dates
occurring from the Original Issue Date to but excluding August 2007, (ii) plus .01%, for Interest
Reset Dates occurring in August 2007, (iii) plus .14%, for Interest Reset Dates occurring from and
including September 2007 to but excluding August 2008, (iv) plus .16%, for Interest Reset Dates
occurring from and including August 2008 to but excluding August 2009, (v) plus .18%, for Interest
Reset Dates occurring from and including August 2009 to but
excluding August 2010 and (vi) plus .20% for Interest Reset Dates occurring from and including August 2010 to but excluding August
2011.

     The Calculation Agent shall calculate the interest rate hereon in accordance with the
foregoing on or before each Calculation Date. The Company hereby covenants for the benefit of the
Holder hereof, to the extent permitted by applicable law, not to claim voluntarily the benefits of
any laws concerning usurious rates of interest against such Holder.

     Merrill Lynch, Pierce, Fenner & Smith Incorporated shall be the “Calculation Agent”. At the
request of the Holder hereof, the Calculation Agent shall provide to the Holder hereof the interest
rate hereon then in effect and, if determined, the interest rate which shall become effective as of
the next Interest Reset Date with respect to this Note.

     Payment of the principal of and interest on this Note shall be made at the Office or Agency of
the Company maintained by the Company for such purpose in the Borough of Manhattan, The City of 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.

     Unless the certificate of authentication hereon has been executed by or on behalf of The Bank
of New York, the Trustee with respect to the Notes under the Indenture, or its successor
thereunder, by the manual signature of one of its authorized officers, this Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

     This Note is one of a duly authorized issue of Securities (hereinafter called the
“Securities”) of the Company designated as its Medium-Term Notes, Series C (the “Notes”). The
Securities are issued and to be issued under an indenture (the “Indenture”) dated as of April 1,
1983, between the Company and The Bank of New York (herein called the “Trustee”, which term
includes any successor Trustee under the Indenture), as amended and restated, to which Indenture
and all indentures supplemental thereto reference is hereby made for a statement of the

3

 

EXHIBIT B-1

respective
rights thereunder of the Company, the Trustee and the Holders of the Notes and the terms upon which
the Notes are to be authenticated and delivered.

     The Notes are issuable only in registered form without coupons in denominations of $1,000 and
integral multiples thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes as
requested by the Holder surrendering the same. If (x) the Depository is at any time unwilling or
unable to continue as depository and a successor depository is not appointed by the Company within
60 days, (y) the Company executes and delivers to the Trustee a Company Order to the effect that
this Note shall be exchangeable or (z) an Event of Default has occurred and is continuing with
respect to the Notes, this Note shall be exchangeable for Notes in definitive form of like tenor
and of an equal aggregate principal amount, in authorized denominations. Such definitive Notes
shall be registered in such name or names as the Depository shall instruct the Trustee. If
definitive Notes are so delivered, the Company may make such changes to the form of this Note as
are necessary or appropriate to allow for the issuance of such definitive Notes.

     This Note is not subject to any sinking fund.

     If an Event of Default (as defined in the Indenture) with respect to the Notes shall occur and
be continuing, the principal of all the Notes may be declared due and payable in the manner and
with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of the Holders of the
Securities of each series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of 66 2/3% in aggregate original public offering price or
principal amount, as the case may be, of the Securities at any time Outstanding, as defined in the
Indenture, of each series affected thereby. Holders of specified percentages in aggregate original
public offering price or principal amount, as the case may be, of the Securities of each series at
the time Outstanding, on behalf of the Holders of all the Securities of each series, are permitted
to waive compliance by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of
this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note
and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the
principal of and interest on this Note at the time, place and rate, and in the coin or currency,
herein prescribed.

     As provided in the Indenture and subject to certain limitations set forth therein and on the
face hereof, the transfer of this Note may be registered on the Security Register of the Company,
upon surrender of this Note for registration of transfer at the office or agency of the Company in
the Borough of Manhattan, The City of New York, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company duly executed by, the Holder hereof or
by his attorney duly authorized in writing, and thereupon one or more new Notes of authorized
denominations and for the same aggregate principal amount, shall be issued to the designated
transferee or transferees.

     No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

     Prior to due presentment of this Note for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name this Note is
registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

     The Indenture and the Notes shall be governed by and construed in accordance with the laws of
the State of New York.

the meanings assigned to them in the Indenture.

MEDIUM-TERM NOTE,

SERIES C

Merrill Lynch Extendible Monthly Securities

(Election not made) (the “Note”)

     MERRILL LYNCH & CO., INC., a Delaware corporation (“Issuer” or the “Company,” which terms
include 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 specified above on
the Stated Maturity specified above, and to pay interest thereon, at a rate per annum determined in
accordance with the provisions hereof, until the principal hereof is paid or duly made available
for payment.

     This Note may not be redeemed at the option of the Company in whole or in part.

     The Company shall pay interest on the 24th calendar day of each month, commencing
August 24, 2006 and on the Stated Maturity (each an “Interest Payment Date”); (such Stated Maturity
and the date on which principal or an installment of principal is due and payable by declaration of
acceleration pursuant to the Indenture being referred to hereinafter as a “Maturity” with respect
to principal payable on such date); provided, however, that if an Interest Payment
Date (other than an Interest Payment Date at Maturity) would fall on a day that is not a Business
Day (as defined below), such Interest Payment Date shall be postponed to the next succeeding day
that is a Business Day. The “Regular Record Date” shall be the date 15
calendar days (whether or not a Business Day) prior to the applicable Interest Payment Date.
Interest on this Note shall accrue from and including the Original Issue Date, at the rates
determined from time to time as specified herein, until the principal hereof has been paid or made
available for payment. The interest 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
Note is registered at the close of business on the Regular Record Date for such Interest Payment
Date. Any such interest which is payable, but not punctually paid or duly provided for on any
Interest Payment Date (herein called “Defaulted Interest”), shall forthwith cease to be

 

 

EXHIBIT B-2

payable to
the registered Holder on such Regular Record Date, and may be paid to the Person in whose name this
Note 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 the Holder of this
Note not less than 10 days prior to such Special Record Date, or may be paid at any time in any
other lawful manner, all as more fully provided in the Indenture.

     The “Interest Rate” borne by this Note shall be LIBOR (as defined below) plus the applicable
Spread (as defined below).

     Commencing on the first Interest Reset Date, the rate at which interest on this Note is
payable shall be reset as of each Interest Reset Date. An “Interest Reset Date” means the
24th calendar day of each month, commencing on August 24, 2006.

     Except as provided above, the interest rate in effect on each day shall be (a) if such day is
an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as
defined below) immediately preceding such Interest Reset Date or (b) if such day is not an Interest
Reset Date, the interest rate determined as of the Interest Determination Date immediately
preceding the immediately preceding Interest Reset Date. LIBOR shall be determined in accordance
with the applicable provision below. If any Interest Reset Date would otherwise be a day that is
not a Business Day, that Interest Reset Date shall be postponed to the next succeeding day that is
a Business Day.

     Interest payable on this Note on any Interest Payment Date shall be the amount of interest
accrued from and including the immediately preceding Interest Payment Date in respect of which
interest has been paid, including any interest paid on the Merrill Lynch Extendible Monthly
Securities issued on August 3, 2006 (or from and including the Original Issue Date specified above,
if no interest has been paid), to but excluding the related Interest Payment Date or Maturity.
Accrued interest hereon shall be an amount calculated by multiplying the face amount hereof by an
accrued interest factor. The accrued interest factor shall be computed by adding the interest
factor calculated for each day in the period for which accrued interest is being calculated. The
interest factor for each such day shall be computed by dividing the interest rate applicable to
each day by 360.

     “Interest Determination Date” means the second London Banking Day (as defined below) preceding
each Interest Reset Date.

     All percentages resulting from any calculation on this Note shall 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 shall be rounded to
the nearest cent with one-half cent being rounded upward.

     As used herein, “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 and such day is also a London Banking Day (as
hereinafter defined).

     As used herein, “London Banking Day” means a day on which commercial banks are open for
business, including dealings in the LIBOR Currency, in London.

     “LIBOR” as determined by the Calculation Agent (as defined below) means:

	 	(1)	 	The
rate for deposits in the LIBOR Currency, as defined below, having an index maturity of
one month commencing on the related Interest Reset Date, that appears on the LIBOR
Page, as defined below, as of 11:00 A.M., London time, on the particular Interest
Determination Date, or
	 
	 	(2)	 	if no rate appears on the particular Interest Determination Date on the LIBOR
Page as specified above, the rate calculated by the Calculation Agent as the arithmetic
mean of at least two offered quotations obtained by the Calculation Agent after
requesting the principal London offices of each of four major reference banks, which
may include affiliates of the Calculation Agent, in the London interbank market to
provide the Calculation Agent with its offered quotation for deposits in the LIBOR
Currency for the period of the index maturity of one month, commencing on the

 

 

EXHIBIT B-2

	 	 	 	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 principal amount
that is representative for single transaction in the LIBOR Currency in that market at
that time, or
	 
	 	(3)	 	if fewer than two offered quotations referred to in clause (2) are provided as
requested, the rate calculated by the Calculation Agent 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 affiliates of the
Calculation Agent, in The City of New York selected by the Calculation Agent for loans
in the LIBOR Currency to leading European banks, having the index maturity of one month
and in principal amount that is representative for single transaction in the LIBOR
Currency in that market at that time, or
	 
	 	(4)	 	if the banks selected by the Calculation Agent are not quoting as mentioned in
clause (3), LIBOR in effect on the particular Interest Determination Date.

     “LIBOR Currency” means United States dollars.

     “LIBOR Page” means the display on Reuters (or any successor service) on page LIBOR01 or any
page as may replace such page on that service for the purpose of displaying the London interbank
rates of major banks for the LIBOR Currency.

     The “Spread” applicable to this Note shall equal (i) minus .02%, for Interest Reset Dates
occurring from the Original Issue Date to but excluding August 2007, (ii) plus .01%, for Interest
Reset Dates occurring in August 2007, (iii) plus .14%, for Interest Reset Dates occurring from and
including September 2007 to but excluding August 2008, (iv) plus .16%, for Interest Reset Dates
occurring from and including August 2008 to but excluding August 2009, (v) plus .18%, for Interest
Reset Dates occurring from and including August 2009 to but
excluding August 2010 and (vi) plus .20% for Interest Reset Dates occurring from and including August 2010 to but excluding August
2011.

     The Calculation Agent shall calculate the interest rate hereon in accordance with the
foregoing on or before each Calculation Date. The Company hereby covenants for the benefit of the
Holder hereof, to the extent permitted by applicable law, not to claim voluntarily the benefits of
any laws concerning usurious rates of interest against such Holder.

     Merrill Lynch, Pierce, Fenner & Smith Incorporated shall be the “Calculation Agent”. At the
request of the Holder hereof, the Calculation Agent shall provide to the Holder hereof the interest
rate hereon then in effect and, if determined, the interest rate which shall become effective as of
the next Interest Reset Date with respect to this Note.

     Payment of the principal of and interest on this Note shall be made at the Office or Agency of
the Company maintained by the Company for such purpose in the Borough of Manhattan, The City of 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.

     Unless the certificate of authentication hereon has been executed by or on behalf of The Bank
of New York, the Trustee with respect to the Notes under the Indenture, or its successor
thereunder, by the manual signature of one of its authorized officers, this Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

     This Note is one of a duly authorized issue of Securities (hereinafter called the
“Securities”) of the Company designated as its Medium-Term Notes, Series C (the “Notes”). The
Securities are issued and to be issued under an indenture (the “Indenture”) dated as of April 1,
1983, between the Company and The Bank of New York (herein called the “Trustee”, which term
includes any successor Trustee under the Indenture), as amended and restated, to which Indenture
and all indentures supplemental thereto reference is hereby made for a statement of the respective
rights thereunder of the Company, the Trustee and the Holders of the Notes and the terms upon which
the Notes are to be authenticated and delivered.

 

 

EXHIBIT B-2

     The Notes are issuable only in registered form without coupons in denominations of $1,000 and
integral multiples thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes as
requested by the Holder surrendering the same. If (x) the Depository is at any time unwilling or
unable to continue as depository and a successor depository is not appointed by the Company within
60 days, (y) the Company executes and delivers to the Trustee a Company Order to the effect that
this Note shall be exchangeable or (z) an Event of Default has occurred and is continuing with
respect to the Notes, this Note shall be exchangeable for Notes in definitive form of like tenor
and of an equal aggregate principal amount, in authorized denominations. Such definitive Notes
shall be registered in such name or names as the Depository shall instruct the Trustee. If
definitive Notes are so delivered, the Company may make such changes to the form of this Note as
are necessary or appropriate to allow for the issuance of such definitive Notes.

     This Note is not subject to any sinking fund.

     If an Event of Default (as defined in the Indenture) with respect to the Notes shall occur and
be continuing, the principal of all the Notes may be declared due and payable in the manner and
with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of the Holders of the
Securities of each series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of 66 2/3% in aggregate original public offering price or
principal amount, as the case may be, of the Securities at any time Outstanding, as defined in the
Indenture, of each series affected thereby. Holders of specified percentages in aggregate original
public offering price or principal amount, as the case may be, of the Securities of each series at
the time Outstanding, on behalf of the Holders of all the Securities of each series, are permitted
to waive compliance by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of
this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note
and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the
principal of and interest on this Note at the time, place and rate, and in the coin or currency,
herein prescribed.

     As provided in the Indenture and subject to certain limitations set forth therein and on the
face hereof, the transfer of this Note may be registered on the Security Register of the Company,
upon surrender of this Note for registration of transfer at the office or agency of the Company in
the Borough of Manhattan, The City of New York, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company duly executed by, the Holder hereof or
by his attorney duly authorized in writing, and thereupon one or more new Notes of authorized
denominations and for the same aggregate principal amount, shall be issued to the designated
transferee or transferees.

     No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

     Prior to due presentment of this Note for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name this Note is
registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

     The Indenture and the Notes shall be governed by and construed in accordance with the laws of
the State of New York.

     All terms used in this Note which are defined in the Indenture but not in this Note shall have
the meanings assigned to them in the Indenture.

Merrill Lynch Extendible Monthly Securities, Series 2

(the “Notes”)

     MERRILL LYNCH & CO., INC., a Delaware corporation (“Issuer” or the “Company,” which terms
include 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 $[•] [•]
DOLLARS) on April 17, 2012, or if such day is not a Business Day (as defined below), the
immediately preceding Business Day (the “Final Stated Maturity Date”) (or such lesser amount as
shall not have been earlier exchanged for other notes pursuant to the terms hereof), and to pay
interest on the principal amount hereof outstanding from time to time, at a rate per annum
determined in accordance with the provisions hereof, until the principal hereof is paid or duly
made available for payment.

     The “Original Issue Date” is March 28, 2007.

     The “Initial Stated Maturity Date” of this Note is April 18, 2008, or if such date is
not a Business Day (as defined herein), the Business Day immediately preceding such date.

     To exercise the option to extend the Note in whole or in part, this Note and the duly
completed form entitled “Option to Extend Maturity” below must be received, by the Trustee (as
defined below) at its office at 111 Sanders Creek Parkway, Syracuse, New York 13057, Attention:
Corporate Trust Operations or such address which the Company shall from time to
time notify the Holders of the Notes (any such office being the “Corporate Trust Office”), no
later than the close of business, New York City time, on the last Business Day during the Notice
Period (as defined herein) for the applicable Election Date (as defined herein). Exercise of such
extension option by the Holder hereof shall be revocable during each day of such Notice Period
until 12:00 noon, New York City time, on the last Business Day in the Notice Period relating to the
applicable election date, at which time such notice will become irrevocable.

 

 

EXHIBIT C-1

     If on any Election Date a Holder does not make an election to extend the maturity date of all
or any portion of the principal amount of this Note, the principal amount of this Note for which
such election was not made shall become due and payable on the Initial Stated Maturity Date or any
Subsequent Stated Maturity Date (as defined below), if applicable, to which the maturity date of
such principal amount shall have previously been extended. The principal amount of this Note for
which such election is not exercised shall be represented by a new Merrill Lynch Extendible Monthly
Security (a “New Note”), issued on the last Business Day of the applicable Notice Period in the
Form of Exhibit A hereto. The New Note so issued shall have the same terms as this Note, except
that it shall not be extendible, shall have a separate CUSIP number and its stated maturity date
shall be the date that is 366 calendar days from and including such Election Date, or if such
366th calendar day is not a Business Day, the immediately preceding Business Day. The
failure to elect to extend the maturity date of all or any portion of this Note shall be
irrevocable and shall be binding upon any subsequent Holder of such notes.

     To exercise the option to extend the maturity date of all or of any portion of this Note
having a principal amount of $1,000 or any multiple of $1,000 in excess thereof the Holder must
deliver notice to the Trustee, during the applicable Notice Period for that Election Date. The new
maturity date for the portion of this Note that has been so extended shall be the 366th calendar
day from and including the 18th calendar day of the next succeeding month immediately
following such Election Date, provided that if such 366th calendar day is not a Business
Day, the new maturity date shall be the immediately preceding Business Day (a “Subsequent Stated
Maturity Date”). A Subsequent Stated Maturity Date cannot occur on any date after the Final Stated
Maturity Date. The date of such Final Stated Maturity Date and the date on which principal or an
installment of principal is due and payable by declaration of acceleration pursuant to the
Indenture is referred to hereinafter as a “Maturity” with respect to principal payable on such
date.

     To the extent that the Trustee has not received a duly completed “Option to Extend Maturity”
form within the applicable election period in accordance with the terms of this Note as to all or
part of the principal amount of this Note, the Trustee shall (a) issue a new Note in the form of
Exhibit A hereto representing such principal amount and (b) reduce or cause to be reduced the
outstanding principal amount of this Note by such amount.

     “Election Date” means the 18th calendar day of each month from April 2007
to March 2011 inclusive, whether or not such day is a Business Day.

     The “Notice Period” for each Election Date shall begin on the fifth scheduled Business Day
prior to the Election Date and end on the Election Date; however, if that Election Date is not a
Business Day, the Notice Period will be extended to the following Business Day.

     This Note may not be redeemed at the option of the Company in whole or in part.

     The Company shall pay interest on the 18th calendar day of each month, commencing
April 18, 2007 and on the Final Stated Maturity Date (each an “Interest Payment Date”);
provided, however, that if an Interest Payment Date (other than an Interest Payment
Date at Maturity) would fall on a day that is not a Business Day, such Interest Payment Date shall
be postponed to the next succeeding day that is a Business Day, except if the Business Day falls in
the next succeeding calendar month, the applicable interest payment date will be the immediately
preceding Business Day. The “Regular Record Date” shall be the date 15 calendar days (whether or
not a Business Day) prior to the applicable Interest Payment Date. Interest on this Note shall
accrue from and including the Original Issue Date, at the rates determined from time to time as
specified herein, until the principal hereof has been paid or made available for payment. The
interest 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 Note is registered at the close
of business on the Regular Record Date for such Interest Payment Date. Any such interest which is
payable, but not punctually paid or duly provided for on any Interest Payment Date (herein called
“Defaulted Interest”), shall forthwith cease to be payable to the registered Holder on such Regular
Record Date, and may be paid to the Person in whose name this Note 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 the Holder of this Note not less than 10 days prior to
such Special Record Date, or may be paid at any time in any other lawful manner, all as more fully
provided in the Indenture.

     The “Interest Rate” borne by this Note shall be LIBOR (as defined below) plus the applicable
Spread (as defined below); provided that for the period from and including the Original Issue Date
to but excluding the initial

5.32395%, a rate based upon an interpolation of two-week LIBOR and one-month LIBOR, to be
determined two London Banking Days (as defined below) prior to the Original Issue Date, minus the
applicable Spread of .02%.

     Commencing on the first Interest Reset Date, the rate at which interest on this Note is
payable shall be reset as of each Interest Reset Date. An “Interest Reset Date” means the
18th calendar day of each month, commencing on April 18, 2007. If any Interest
Reset Date would otherwise be a day that is not a Business Day, that Interest Reset Date shall be
postponed to the next succeeding day that is a Business Day, except if the Business Day falls in
the next succeeding calendar month, the applicable interest payment date will be the immediately
preceding Business Day.

     Except as provided above, the interest rate in effect on each day shall be (a) if such day is
an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as
defined below) immediately preceding such Interest Reset Date or (b) if such day is not an Interest
Reset Date, the interest rate determined as of the Interest Determination Date immediately
preceding the immediately preceding Interest Reset Date. LIBOR shall be determined in accordance
with the applicable provision below.

     Interest payable on this Note on any Interest Payment Date shall be 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 Original Issue Date specified above, if no
interest has been paid), to but excluding the related Interest Payment Date or Maturity. Accrued
interest hereon shall be an amount calculated by multiplying the face amount hereof by an
accrued interest factor. The accrued interest factor shall be computed by adding the interest
factor calculated for each day in the period for which accrued interest is being calculated. The
interest factor for each such day shall be computed by dividing the interest rate applicable to
each day by 360.

     “Interest Determination Date” means the second London Banking Day preceding each Interest
Reset Date.

     All percentages resulting from any calculation on this Note shall 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 shall be rounded to the nearest cent
with one-half cent being rounded upward.

     As used herein, “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 and such day is also a London Banking Day.

     As used herein, “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.

     “LIBOR” as determined by the Calculation Agent (as defined below) means:

	 	(1)	 	The rate for deposits in the LIBOR Currency, having an index maturity of one month
commencing on the related Interest Reset Date, that appears on the LIBOR Page, as
defined below, as of 11:00 A.M., London time, on the particular Interest Determination
Date, or
	 
	 	(2)	 	if no rate appears on the particular Interest Determination Date on the LIBOR
Page as specified above, the rate calculated by the Calculation Agent as the arithmetic
mean of at least two offered quotations obtained by the Calculation Agent after
requesting the principal London offices of each of four major reference banks, which
may include affiliates of the Calculation Agent, in the London interbank market to
provide the Calculation Agent with its offered quotation for deposits in the LIBOR
Currency for the period of the index maturity of one month, 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 the LIBOR Currency in that market at
that time, or
	 
	 	(3)	 	if fewer than two offered quotations referred to in clause (2) are provided as
requested, the rate calculated by the Calculation Agent as the arithmetic mean of the
rates quoted at approximately

3

 

EXHIBIT C-1

	 	 	 	11:00 A.M., in The City of New York, on the particular
Interest Determination Date by three major banks, which may include affiliates of the
Calculation Agent, in The City of New York selected by the Calculation Agent for loans
in the LIBOR Currency to leading European banks, having the index maturity of one month
and in a principal amount that is representative for a single transaction in the LIBOR
Currency in that market at that time, or
	 
	 	(4)	 	if the banks selected by the Calculation Agent are not quoting as mentioned in
clause (3), LIBOR in effect on the particular Interest Determination Date.

     “LIBOR Currency” means United States dollars.

     “LIBOR Page” means the display on Reuters (or any successor service) on page LIBOR01 or any
page as may replace such page on that service for the purpose of displaying the London interbank
rates of major banks for the LIBOR Currency.

     The “Spread” applicable to this Note shall equal (i) minus .02%, for Interest Reset
Dates occurring from the Original Issue Date to but excluding
September 2007, (ii) plus .14%, for Interest Reset Dates occurring from and including September 2007 to but excluding
April 2008, (iii) plus .16%, for Interest Reset Dates occurring from and including April
2008 to but excluding April 2009, (iv) plus .18%, for Interest Reset Dates occurring from
and including April 2009 to but excluding April 2010, (v) plus .20%, for Interest Reset
Dates occurring from and including April 2010 to but excluding April 2011 and (vi) plus .20% , for
Interest Reset Dates occurring from and including April 2011 to but excluding April 2012.

     The Calculation Agent shall calculate the interest rate hereon in accordance with the
foregoing on or before each Interest Determination Date. The Company hereby covenants for the
benefit of the Holder hereof, to the extent permitted by applicable law, not to claim voluntarily
the benefits of any laws concerning usurious rates of interest against such Holder.

     Merrill Lynch, Pierce, Fenner & Smith Incorporated shall be the “Calculation Agent”. At the
request of the Holder hereof, the Calculation Agent shall provide to the Holder hereof the interest
rate hereon then in effect and, if determined, the interest rate which shall become effective as of
the next Interest Reset Date with respect to this Note.

     Payment of the principal of and interest on this Note shall be made at the Office or Agency of
the Company maintained by the Company for such purpose in the Borough of Manhattan, The City of 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.

     Unless the certificate of authentication hereon has been executed by or on behalf of The Bank
of New York, the Trustee with respect to the Notes under the Indenture, or its successor
thereunder, by the manual signature of one of its authorized officers, this Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

     This Note is one of a duly authorized issue of Securities (hereinafter called the
“Securities”) of the Company designated as its Medium-Term Notes, Series C (the “Notes”). The
Securities are issued and to be issued under an indenture (the “Indenture”) dated as of April 1,
1983, between the Company and The Bank of New York, (herein called the “Trustee”, which term
includes any successor Trustee under the Indenture), as amended and restated, to which Indenture
and all indentures supplemental thereto reference is hereby made for a statement of the respective
rights thereunder of the Company, the Trustee and the Holders of the Notes and the terms upon which
the Notes are to be authenticated and delivered.

     The Notes are issuable only in registered form without coupons in denominations of $1,000 and
integral multiples thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes as
requested by the Holder surrendering the same. If (x) the Depository is at any time unwilling or
unable to continue as depository and a successor depository is not appointed by the Company within
60 days, (y) the Company executes and delivers to the Trustee a Company
Order to the effect that this Note shall be exchangeable or (z) an Event of Default (as
defined in the Indenture) has

occurred and is continuing with respect to the Notes, this Note shall
be exchangeable for Notes in definitive form of like tenor and of an equal aggregate principal
amount, in authorized denominations. Such definitive Notes shall be registered in such name or
names as the Depository shall instruct the Trustee. If definitive Notes are so delivered, the
Company may make such changes to the form of this Note as are necessary or appropriate to allow for
the issuance of such definitive Notes.

     This Note is not subject to any sinking fund.

     If an Event of Default with respect to the Notes shall occur and be continuing, the principal
of all the Notes may be declared due and payable in the manner and with the effect provided in the
Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of the Holders of the
Securities of each series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of 66 2/3% in aggregate original public offering price or
principal amount, as the case may be, of the Securities at any time Outstanding, as defined in the
Indenture, of each series affected thereby. Holders of specified percentages in aggregate original
public offering price or principal amount, as the case may be, of the Securities of each series at
the time Outstanding, on behalf of the Holders of all the Securities of each series, are permitted
to waive compliance by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of
this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note
and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the
principal of and interest on this Note at the time, place and rate, and in the coin or currency,
herein prescribed.

     As provided in the Indenture and subject to certain limitations set forth therein and on the
face hereof, the transfer of this Note may be registered on the Security Register of the Company,

the Borough of Manhattan, The City of New York, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company duly executed by, the Holder hereof or
by his attorney duly authorized in writing, and thereupon one or more new Notes of authorized
denominations and for the same aggregate principal amount, shall be issued to the designated
transferee or transferees.

     No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

     The Company and each Holder (and each beneficial owner) of this Note, by virtue of the
purchase and ownership of this Note, agree, for U.S. federal income tax purposes, to (i) treat this
Note as a variable rate debt
instrument and (ii) not treat any election or series of elections to extend the maturity date
of this Note as resulting in a taxable exchange of this Note.

(Election not made) (the “Note”)

     MERRILL LYNCH & CO., INC., a Delaware corporation (“Issuer” or the “Company,” which terms
include 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 specified above on
the Stated Maturity specified above, and to pay interest thereon, at a rate per annum determined in
accordance with the provisions hereof, until the principal hereof is paid or duly made available
for payment.

     This Note may not be redeemed at the option of the Company in whole or in part.

     The Company shall pay interest on the 18th calendar day of each month,
commencing April 18, 2007 and on the Stated Maturity (each an “Interest Payment Date”);
(such Stated Maturity and the date on which principal or an installment of principal is due and
payable by declaration of acceleration pursuant to the Indenture being referred to hereinafter as a
“Maturity” with respect to principal payable on such date); provided, however, that
if an Interest Payment Date (other than an Interest Payment Date at Maturity) would fall on a day
that is not a Business Day (as defined below), such Interest Payment Date shall be postponed to the
next succeeding day that is a Business Day, except if the Business Day falls in the next
succeeding calendar month, the applicable interest payment date will be the immediately
preceding Business Day. The “Regular Record Date” shall be the date 15 calendar days (whether or
not a Business Day) prior to the applicable Interest Payment Date. Interest on this Note shall
accrue from and including the Original Issue Date, at the rates determined from time to time as
specified herein, until the principal hereof has been paid or made available for payment. The
interest 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 Note is registered at the close
of business on the Regular Record Date for such Interest Payment Date. Any such interest

 

 

EXHIBIT C-1

which is
payable, but not punctually paid or duly provided for on any Interest Payment Date (herein called
“Defaulted Interest”), shall forthwith cease to be payable to the registered Holder on such Regular
Record Date, and may be paid to the Person in whose name this Note 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 the Holder of this Note not less than 10 days prior to
such Special Record Date, or may be paid at any time in any other lawful manner, all as more fully
provided in the Indenture.

     The “Interest Rate” borne by this Note shall be LIBOR (as defined below) plus the applicable
Spread (as defined below).

     Commencing on the first Interest Reset Date, the rate at which interest on this Note is
payable shall be reset as of each Interest Reset Date. An “Interest Reset Date” means the
18th calendar day of each month, commencing on the first April 18th after the
Original Issue Date. If any Interest Reset Date would otherwise be a day that is not a Business
Day, that Interest Reset Date shall be postponed to the next succeeding day that is a Business Day,
except if the Business Day falls in the next succeeding calendar month, the applicable interest
payment date will be the immediately preceding Business Day.

     The interest rate in effect on each day shall be (a) if such day is an Interest Reset Date,
the interest rate determined as of the Interest Determination Date (as defined below) immediately
preceding such Interest Reset Date or (b) if such day is not an Interest Reset Date, the interest
rate determined as of the Interest Determination Date immediately preceding the immediately

specified above, if no interest has been paid), to but excluding the related Interest Payment Date
or Maturity. Accrued interest hereon shall be an amount calculated by multiplying the face amount
hereof by an accrued interest factor. The accrued interest factor shall be computed by adding the
interest factor calculated for each day in the period for which accrued interest is being
calculated. The interest factor for each such day shall be computed by dividing the interest rate
applicable to each day by 360.

     “Interest Determination Date” means the second London Banking Day (as defined below) preceding
each Interest Reset Date.

     All percentages resulting from any calculation on this Note shall be rounded to the nearest
one hundred-thousandth of a percentage point, with five one-millionths of a percentage point

integral multiples thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes as
requested by the Holder surrendering the same. If (x) the Depository is at any time unwilling or

definitive form of like tenor and of an equal aggregate principal amount, in authorized
denominations. Such definitive Notes shall be registered in such name or names as the Depository
shall instruct the Trustee. If definitive Notes are so delivered, the Company may make such
changes to the form of this Note as are necessary or appropriate to allow for the issuance of such
definitive Notes.

     This Note is not subject to any sinking fund.

     If an Event of Default with respect to the Notes shall occur and be continuing, the principal
of all the Notes may be declared due and payable in the manner and with the effect provided in the
Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of the Holders of the
Securities of each series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of 66 2/3% in aggregate original public offering price or
principal amount, as the case may be, of the Securities at any time Outstanding, as defined in the
Indenture, of each series affected thereby. Holders of specified percentages in aggregate original
public offering price or principal amount, as the case may be, of the Securities of each series at
the time Outstanding, on behalf of the Holders of all the Securities of each series, are permitted
to waive compliance by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of
this Note shall be conclusive and binding upon
such Holder and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of
such consent or waiver is made upon this Note.

denominations and for the same aggregate principal amount, shall be issued to the designated
transferee or transferees.

Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

thereunder, by the manual signature of one of its authorized officers, this Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

     This Note is one of a duly authorized issue of Securities (hereinafter called the
“Securities”) of the Company designated as its Medium-Term Notes, Series C (the “Notes”). The
Securities are issued and to be issued under an indenture (the “Indenture”) dated as of April 1,
1983, between the Company and The Bank of New York, (herein called the “Trustee”, which term
includes any successor Trustee under the Indenture), as amended and restated, to which Indenture
and all indentures supplemental thereto reference is hereby made for a statement of the

 

 

EXHIBIT C-2

respective
rights thereunder of the Company, the Trustee and the Holders of the Notes and the terms upon which
the Notes are to be authenticated and delivered.

     The Notes are issuable only in registered form without coupons in denominations of $1,000 and
integral multiples thereof. As provided in the Indenture and subject to certain limitations
therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes as
requested by the Holder surrendering the same. If (x) the Depository is at any time unwilling or
unable to continue as depository and a successor depository is not appointed by the Company within
60 days, (y) the Company executes and delivers to the Trustee a Company Order to the effect that
this Note shall be exchangeable or (z) an Event of Default (as defined in the Indenture) has
occurred and is continuing with respect to the Notes, this Note shall be exchangeable for Notes in
definitive form of like tenor and of an equal aggregate principal amount, in authorized
denominations. Such definitive Notes shall be registered in such name or names as the Depository
shall instruct the Trustee. If definitive Notes are so delivered, the Company may make such
changes to the form of this Note as are necessary or appropriate to allow for the issuance of such
definitive Notes.

     This Note is not subject to any sinking fund.

     If an Event of Default with respect to the Notes shall occur and be continuing, the principal
of all the Notes may be declared due and payable in the manner and with the effect provided in the
Indenture.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of the Holders of the
Securities of each series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of 66 2/3% in aggregate original public offering price or
principal amount, as the case may be, of the Securities at any time Outstanding, as defined in the
Indenture, of each series affected thereby. Holders of specified percentages in aggregate original
public offering price or principal amount, as the case may be, of the Securities of each series at
the time Outstanding, on behalf of the Holders of all the Securities of each series, are permitted
to waive compliance by the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of
this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note
and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the
principal of and interest on this Note at the time, place and rate, and in the coin or currency,
herein prescribed.

     As provided in the Indenture and subject to certain limitations set forth therein and on the
face hereof, the transfer of this Note may be registered on the Security Register of the Company,
upon surrender of this Note for registration of transfer at the office or agency of the Company in
the Borough of Manhattan, The City of New York, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company duly executed by, the Holder hereof or
by his attorney duly authorized in writing, and thereupon one or more new Notes of authorized
denominations and for the same aggregate principal amount, shall be issued to the designated
transferee or transferees.

     No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

     Prior to due presentment of this Note for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name this Note is
registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

     The Indenture and the Notes shall be governed by and construed in accordance with the laws of
the State of New York.

     All terms used in this Note which are defined in the Indenture but not in this Note shall have
the meanings assigned to them in the Indenture.
