EXTENDIBLE SENIOR UNSECURED FLOATING RATE NOTES INITIALLY DUE 2008




          NATIONAL RURAL UTILITIES COOPERATIVE FINANCE CORPORATION, a District of Columbia cooperative
association (herein called the “Company”, which term includes any successor Person under the
Indenture referred to on the reverse hereof), for value received, hereby promises to pay to CEDE &
Co., or registered assigns, the principal sum of $250,000,000 on May 1, 2008, or, if such day is
not a Business Day, the immediately following Business Day (the “initial maturity date”), unless
the maturity of all or any portion of the principal amount of the Notes is extended in accordance
with the procedures set forth below, but in no event will the maturity of the Notes be extended
beyond May 1, 2014 or, if such day is not a Business Day, the immediately following Business Day
(the “final maturity date”); and to pay interest thereon as set forth below, until the principal
hereof is paid or made available for payment.




          During a notice period for any election date (each as defined below), the maturity of all or
any portion of the principal amount of the Notes may be extended to the actual maturity date
occurring thirteen months after that election date. The election dates will be the third calendar
day of each month, commencing on May 3, 2007, provided that if such day is not a Business Day, the
election date will be extended to the next succeeding Business Day. The actual maturity date will
be the initial maturity date, the final maturity date and the 1st calendar day of each
month, commencing on May 1, 2008, provided that if such day is not a Business Day, the payment of
principal and interest may be made on the next succeeding Business Day as if it were



 









 







made on the date that the payment was due, and no interest on such principal will accrue for
the period from and after the actual maturity date.



          The maturity of all or any portion of the Notes having a principal amount of $2,000 or any
multiple of $1,000 in excess thereof may be extended. To make this election effective on any
election date, a holder of the Notes must deliver a notice of election during the notice period for
that election. The “notice period” for each election date will begin on the tenth Business Day
prior to the election date and end at 12:00 noon (New York City time) two Business Days immediately
preceding the election date; provided that if the election date is not a Business Day, the notice
period will be extended to 12:00 noon (New York City time) on the following Business Day. The
notice of election must be delivered through the normal clearing system channels described in more
detail below, no later than 12:00 noon, New York City time, on the last Business Day in the notice
period. Upon delivery to the Trustee of such notice of election to extend the maturity of the
Notes or any portion thereof during a notice period, the election will be revocable during each day
of such notice period, until 12:00 noon, New York City time, on the last Business Day in such
notice period, at which time such notice will become irrevocable.




          If, with respect to any election date, a holder of the Notes does not make an election to
extend the maturity date of all or any portion of the principal amount of its Notes, the principal
amount of the Notes for which such holder has failed to make an election will become due and
payable on the initial maturity date, or any later actual maturity date to which the maturity date
of the Notes has previously been extended. The principal amount of the Notes for which such
election is not exercised will be represented by a note issued on such election date. The note so
issued will have the same terms and form part of the same series as the Notes, except that it will
not be extendible, will have a separate CUSIP number and its maturity date will be the date that is
the actual maturity date that corresponds to such election date or, if such maturity date is not a
Business Day, the next succeeding Business Day. The failure to elect to extend the maturity of all
or any portion of the Notes will be irrevocable and will be binding upon any subsequent holder of
such Notes.




          The Notes will be issued in registered global form and will remain on deposit with the
Depository Trust Company (“DTC”), as depositary for the Notes. Therefore, each holder of the Notes
must exercise the option to extend the maturity of such Notes through DTC. To ensure that DTC will
receive timely notice of any holder’s election to extend the maturity of all or a portion of the
Notes, the holder must instruct the direct or indirect participant through which it holds an
interest in the Notes to notify DTC of such election in accordance with the then applicable
operating procedures of DTC. DTC must be timely notified of such election so that it can deliver
notice thereof to the Trustee prior to the close of business on the last Business Day in the notice
period.




          DTC must receive any notice of election or any notice of revocation of a previous election
from its participants no later than 12:00 noon, New York City time, on the last Business Day of the
notice period for any election date. Different firms have different deadlines for accepting
instructions from their customers and holders of Notes should consult the direct or



 









 







indirect participant through which they hold an interest in the Notes to ascertain the
deadline for ensuring that timely notice will be delivered to DTC.



          The Notes will bear interest at three month US dollar LIBOR plus or minus the applicable
spread, as described below, provided, however, the interest for the final interest period ending on
the actual maturity date will be calculated according to one month US dollar LIBOR, if the final
interest period is a period of one month, two month US dollar LIBOR, if the final interest period
is a period of two months, or three month US dollar LIBOR, if the final interest period is a period
of three months. Interest will be paid quarterly in arrears on the 1st calendar day of each May,
August, November and February, beginning on August 1, 2007, and on the applicable actual maturity
date. If any date on which interest is scheduled to be paid falls on a day that is not a Business
Day (each, an “original interest payment date”), the making of such interest payment will be
postponed to the next succeeding Business Day (and interest will accrue to but excluding that next
succeeding Business Day) unless, (a) such next succeeding Business Day is in the next calendar
month or (b) such original interest payment date is also a maturity date, in which case the date on
which interest is to be paid will be the immediately preceding Business Day (and interest will
accrue to but excluding that immediately preceding Business Day). A date on which an interest
payment is made (following any adjustment made in accordance with the terms of the immediately
preceding sentence) is referred to as an “interest payment date.” The final interest payment date
for the Notes, or any portion of the Notes maturing prior to the final maturity date, will be the
applicable maturity date, and interest for the last interest period preceding the final maturity
date (as set forth below) will accrue from and including the interest payment date immediately
preceding such maturity date to but excluding the maturity date (as adjusted as described in the
third sentence of this paragraph if such maturity date is not a Business Day). Interest on the
Notes will be computed on the basis of a 360-day year and the actual number of days elapsed.




          Interest on the Notes will accrue from and including April 10, 2007 to but excluding the first
interest payment date and then from and including each interest payment date to which interest has
been paid or duly provided for to but excluding the next interest payment date or the applicable
maturity date, as the case may be (following any adjustment made in accordance with the terms of
the immediately preceding paragraph). Each of these periods is referred to as an “interest period.”




          The Company will pay interest on the Notes to the persons in whose names the Notes are
registered at the close of business on the Business Day immediately preceding the interest payment
date. However, the Company will pay interest on the maturity date to the same persons to whom the
principal will be payable.




          The Trustee has been initially appointed as calculation agent. The calculation agent will
calculate the interest rate on the Notes and reset the interest rate on each interest payment date
(or the issue date, in the case of the first interest period), each of which is referred to as an
“interest reset date,” for the interest period commencing on such date to but excluding the next
interest payment date (or the maturity date, in the case of the final interest period). The
interest rate for each interest period will be equal to LIBOR, plus or minus the spread, as
determined below:




 









 





	 	 	 
	For Interest Reset Dates Occurring	 	Spread
	From and including April 10, 2007 to and including April 30, 2008

	 	Plus 0.00%
	From and including May 1, 2008 to and including April 30, 2009

	 	Plus 0.01%
	From and including May 1, 2009 to and including April 30, 2010

	 	Plus 0.02%
	From and including May 1, 2010 to and including April 30, 2011

	 	Plus 0.03%
	From and including May 1, 2011 to and including April 30, 2012

	 	Plus 0.04%
	From and including May 1, 2012 to and including April 30, 2013

	 	Plus 0.05%
	From and including May 1, 2013 to and including April 30, 2014

	 	Plus 0.05%






          The interest rate in effect for the period from April 10, 2007 to but excluding May 1,
2007 (the “initial interest reset date”) will be three month US dollar LIBOR, as determined on
April 9, 2007 (the “initial interest rate”). The second London Banking Day preceding an interest
reset date will be the “interest determination date’’ for that interest reset date. The interest
rate in effect on each day that is not an interest reset date will be the interest rate determined
as of the interest determination date pertaining to the immediately preceding interest reset date.
The interest rate in effect on any day that is an interest reset date will be the interest rate
determined as of the interest determination date pertaining to that interest reset date, except
that the interest rate in effect for the period from and including April 10, 2007, to but excluding
the next succeeding interest reset date will be the initial interest rate.




          The calculation agent will, upon the request of the holder of any Notes, provide the interest
rate then in effect. All calculations of the calculation agent, in the absence of manifest error,
shall be conclusive for all purposes and binding on the Company and holders of the Notes.




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




          Unless the certificate of authentication hereon has been executed by the Trustee referred to
on the reverse hereof, directly or through an Authenticating Agent, by manual signature of an
authorized signatory, this Note shall not be entitled to any benefit under the Indenture or be
valid or obligatory for any purpose.




 









 





     IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed under its

REVERSE OF NOTE




          This Note is one of a duly authorized issue of securities of the Company (herein called the
“Notes”), issued and to be issued in one or more series under an Indenture dated as of December 15,
1987, as supplemented by a First Supplemental Indenture dated as of October 1, 1990 (the Indenture
as so supplemented being herein called the “Indenture”), between the Company and U.S. Bank National
Association, as successor trustee (herein called the “Trustee”, which term includes any successor
trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms
upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the
series designated Extendible Senior Unsecured Floating Rate Notes Initially Due 2008.




          Each Note of this series shall be dated the date of its authentication by the Trustee. Each
Note of this series shall also bear an Original Issue Date, as specified on the face hereof, and
such Original Issue Date shall remain the same for all Notes subsequently issued upon transfer,
exchange or substitution of such original Note (or such subsequently issued Notes) regardless of
their dates of authentication.




          The Notes may not be redeemed by the Company prior to maturity.




          For purposes of this Note the following terms shall have the following meanings:




          “Business Day” means any day other than a Saturday or Sunday that is neither a legal holiday
nor a day on which banking institutions are authorized or required by law or regulation to close in
New York City which is also a London Banking Day.




          “Designated LIBOR Page” means the display on Reuters 3000 Xtra (or any successor service) on
Reuters Page LIBOR01, or any other page as may replace the page on the service, for the purpose of
displaying the London interbank rates of major banks of U.S. dollar deposits.




          “LIBOR” will be determined by the calculation agent in accordance with the following
provisions:






(a) the calculation agent will determine the offered rate for deposits in United
States dollars for the three-month period commencing on the applicable interest
reset date that appears on the Designated LIBOR Page as of 11:00 A.M., London Time,
on the applicable interest determination date. If fewer than two offered rates
appear or no rate appears, LIBOR on the interest determination date will be
determined in accordance with the provisions described in paragraph (b) set forth
below.




(b) With respect to an interest determination date on which fewer than two offered
rates appear or no rate appears on the Designated LIBOR Page as specified in (a)
above, LIBOR will be determined according to the procedures described below.



 









 






     The calculation agent will request the principal London offices of each of four
major reference banks (which may include affiliates of the underwriters) in the
London interbank market, as selected by the calculation agent, to provide the
calculation agent with its offered quotation for deposits in United States dollars
for the three-month period commencing on the first day of the relevant interest
period, to prime banks in the London interbank market at approximately 11:00 A.M.,
London time, on the interest determination date and in a principal amount that is
representative for a single transaction in United States dollars in the market at
the time.




     If at least two quotations are so provided, then LIBOR on the interest
determination date will be the arithmetic mean of the quotations.




     If fewer than two quotations are so provided, the LIBOR on the interest
determination date will be arithmetic mean of the rates quoted at approximately
11:00 A.M., London time, in the applicable principal financial center, on the
interest determination date by three major banks (which may include affiliates of
the underwriters) in the principal financial center selected by the calculation
agent for loans in United States dollars to leading European banks for the
three-month period and in a principal amount that is representative for a single
transaction in United States dollars in the market at the time.




     If the banks so selected by the calculation agent are not quoting as provided
above, LIBOR determined as of the interest determination date will be LIBOR in
effect for the Notes on that interest determination date.



          “London Banking Day” means any day on which dealings in deposits in U.S. dollars are
transacted in the London interbank market.




          The Company at its option, subject to the terms and conditions provided in the Indenture, (a)
will be discharged from any and all obligations in respect of the Notes (except for certain
obligations including obligations to register the transfer or exchange of Notes, replace stolen,
lost or mutilated Notes, maintain paying agencies and hold moneys for payment in trust) or (b) need
not comply with certain restrictive covenants of the Indenture after the Company deposits with the
Trustee (or, in certain circumstances, 91 days after the Company deposits with the Trustee),
pursuant to an escrow trust agreement, money or U.S. Government Obligations, or a combination of
money and U.S. Government Obligations, which through the payment of interest thereon and principal
thereof in accordance with their terms will provide money in an amount sufficient to pay all the
principal of, and interest on, the Notes on the dates such payments are due in the currency,
currencies or currency unit or units, in which such Notes are payable and in accordance with the
terms of the Notes.




          If an Event of Default with respect to Notes of this series shall occur and be continuing, the
principal of the Notes of this series 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
Notes 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 not less than a majority in principal amount of the Outstanding
Securities of all series affected thereby (acting as one class). The Indenture also contains
provisions permitting the Holders of not less than a majority in principal amount of the
Outstanding Securities of all series affected thereby (acting as one class), on behalf of the
Holders of all Notes of each such series, to waive compliance by the Company with certain
provisions of the Indenture. The Indenture also provides that, regarding the Notes of any series,
the Holders of not less than a majority in principal amount of the Outstanding Securities of such
series may waive certain past defaults and their consequences on behalf of the Holders of all Notes
of such series. 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.




          As set forth in, and subject to, the provisions of the Indenture, no Holder of any Note of
this series will have any right to institute any proceeding with respect to the Indenture or for
any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice
of a continuing Event of Default with respect to this series, the Holders of not less than 25% in
principal amount of the Outstanding Securities of this series shall have made written request, and
offered reasonable indemnity, to the Trustee to institute such proceeding as trustee, the Trustee
shall not have received from the Holders of a majority in principal amount of the Outstanding
Securities of this series a direction inconsistent with such request and the Trustee shall have
failed to institute such proceeding within 60 days; provided, however, that such limitations do not
apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of
(and premium, if any) or interest on this Note on or after the respective due dates expressed herein.




          No reference herein to the Indenture and no provision of this Note or the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the
principal of (and premium, if any) and interest on this Note at the times, places and rate, and in
the coin or currency, herein prescribed.




          As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Note is registrable in the Security Register, upon surrender of this Note for
registration of transfer at the office or agency as may be designated by 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 and the Security Registrar duly executed by the Holder
hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this
series and of the tenor and terms, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.




 









 








          The Notes of this series are issuable only in registered form, without coupons, in minimum
denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Notes of this series are
exchangeable for a like aggregate principal amount of Notes of this series and of like tenor and
terms of a different authorized denomination, as requested by the Holder surrendering the same.




          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 is 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.

assigned to them in the Indenture.
