NOMINEE OF THE DEPOSITORY OR BY THE DEPOSITORY OR ANY SUCH NOMINEE TO A

LEHMAN BROTHERS HOLDINGS INC., a corporation duly organized and existing
under the laws of the State of Delaware (herein called the “Company,” which
term includes any successor corporation under the Indenture referred to on the
reverse hereof), for value received, hereby promises to pay to CEDE & Co.,
or registered assigns, on the Maturity Date, an amount equal to the Redemption
Amount.


The “Maturity Date” is April 16, 2008, or if such day is not a Business
Day, on the next following Business Day.


The “Redemption Amount” is the amount equal to the sum of the principal
amount of the Notes plus the Additional Amount, if any.


The “Additional Amount” is a single U.S. Dollar amount equal the
principal amount of the Notes multiplied by the Leverage multiplied by the
Basket Value, provided that the minimum
Additional Amount payable on the Notes shall be zero.


The “Leverage” is 235%.


The “Reference Currencies” are the Brazilian
Real (BRL), the Russian Ruble (RUB), the Indian Rupee (INR) and the Chinese
Renminbi (CNY).


The “Basket Value” equals the sum of:


(i) a quotient, the numerator of which is 0.5076 and the denominator of which is the Settlement Rate for BRL plus


(ii) a quotient, the numerator of which is 6.4913 and the denominator of which is the Settlement Rate for RUB plus


(iii) a quotient, the numerator of which is 10.7125 and the denominator of which is the Settlement Rate for INR plus


(iv) a quotient, the numerator of which is 1.9336 and the denominator of which is the Settlement Rate for CNY plus


(v) a quotient, the numerator of
which is -1.0000 and the
denominator of which is the Settlement Rate for USD.


The “Settlement
Rate” for each Reference Currency is the Reference Exchange Rate on the
Valuation Date, determined in accordance with the Settlement Rate Option
(subject to the occurrence of a Disruption Event).  The Settlement Rate for the USD shall be 1.


The “Reference
Exchange Rates” are the spot exchange rates for each of the Reference
Currencies quoted against the U.S. Dollar expressed as number of currency units
per USD 1.


The “Trade Date” is April 4, 2007.


The “Valuation Date” is April 7, 2008;
provided that, upon the occurrence of a Disruption Event with respect to a
Reference Currency, the Valuation Date for the affected Reference Currency may
be postponed (as described in “Disruption Events” below).



 2
 









If the
Calculation Agent determines that a Disruption Event relating to one or more of
the Reference Currencies is in effect on the scheduled Valuation Date, the
Calculation Agent will determine the Basket Value using:


·                                          for each Reference
Currency that did not suffer a Disruption Event on the scheduled Valuation
Date, the Settlement Rate on the scheduled Valuation Date, and


·                                          for each Reference
Currency that did suffer a Disruption Event on the scheduled Valuation Date,
the Settlement Rate on the immediately succeeding scheduled Valuation Business
Day for such Reference Currency on which no Disruption Event occurs or is
continuing with respect to such Reference Currency;


provided, however, that if a
Disruption Event has occurred or is continuing with respect to a Reference
Currency on each of the three scheduled Valuation Business Days following the
scheduled Valuation Date, then (a) such third scheduled Valuation Business Day
shall be deemed the Valuation Date for the affected Reference Currency; and (b)
the Calculation Agent will determine the Settlement Rate for the affected
Reference Currency on such day in accordance with Fallback Rate Observation
Methodology.


For
purposes of the above, “scheduled Valuation Business Day” means a day that is
or, in the judgment of the Calculation Agent, should have been, a Valuation
Business Day for the affected Reference Currency.


A “Disruption
Event” means any of the
following events as determined in good faith by the Calculation Agent:


(A)                              the occurrence and/or existence of an event on any
day that has the effect of preventing or making impossible the delivery of USD
from accounts inside the country for which a Reference Currency is the lawful
currency (such jurisdiction with respect to such Reference Currency, the “Reference
Currency Jurisdiction”) for that Reference Currency to accounts outside that
Reference Currency Jurisdiction;


(B)                                the occurrence of any
event causing the Reference Exchange Rate for the Reference Currency to be
split into dual or multiple currency exchange rates; or


(C)                                the Settlement Rate being unavailable for the
Reference Currency, or the occurrence of an event (i) in the Reference Currency
Jurisdiction for that Reference Currency that materially disrupts the market
for the Reference Currency or (ii) that generally makes it impossible to obtain
the Settlement Rate for the Reference Currency, on the Valuation Date.


A “Valuation Business Day” means,
with respect to each Reference Currency, 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
(including for dealings in foreign exchange in accordance with the practice of
the foreign exchange market) in the city or jurisdiction indicated in the table
below:

The “Settlement Rate Option”
for the BRL is the Brazilian Real/U.S. Dollar offered rate for U.S. Dollars,
expressed as the amount of Brazilian Reals per one U.S. Dollar, for settlement
in two Business Days reported by the Banco Central do Brasil on SISBACEN Data
System under transaction code PTAX-800 (“Consulta de Cambio” or Exchange Rate
Inquiry), Option 5 (“Cotacoes para Contabilidade” or Rates for Accounting
Purposes), which appears on Reuters Screen BRFR Page under the caption “Dolar
PTAX” at approximately 6:30 pm Sao Paolo time on the Valuation Date or such
other relevant date.  The Settlement Rate
Option for the RUB is the Russian Ruble/U.S. Dollar Specified Rate, expressed
as the amount of Russian Rubles per one U.S. Dollar, for settlement in one
Business Day, calculated by the Chicago Mercantile Exchange (“CME”) and as
published on CME’s website, which appears on the Reuters Screen EMTA Page, at
approximately 1:30 p.m., Moscow time, on the Valuation Date or such other
relevant date.  The Settlement Rate
Option for the INR is the Indian Rupee/U.S. Dollar reference rate, expressed as
the amount of Indian Rupee per one U.S. Dollar, for settlement in two Business
Days reported by the Reserve Bank of India which appears on the Reuters Screen
RBIB Page at approximately 2:30 p.m., Mumbai time, or as soon thereafter as
practicable on the Valuation Date or such other relevant date.  The Settlement Rate Option for the CNY is the
Chinese Renminbi/U.S. Dollar official fixing rate, expressed as the amount of
Chinese Renminbi per one U.S. Dollar, for settlement in two Business Days
reported by The State Administration of Foreign Exchange of the People’s
Republic of China, Beijing, which appears on the Reuters Screen SAEC Page
opposite the symbol “USDCNY=“ at approximately 5:00 p.m., Beijing time, on the
Valuation Date or such other relevant date.


The screen or time of observation
indicated in relation to any Settlement Rate Option above shall be deemed to
refer to such screen or time of observation as modified or amended from time to
time, or to any substitute screen thereto.


The “Fallback
Rate Observation Methodology” means
that the reference exchange rate, Settlement Rate or other rate, as specified
in the applicable pricing supplement, in respect of a reference currency will
equal the noon buying rate in New York for cable transfers in foreign
currencies as announced by the Federal Reserve Bank of New York for customs
purposes (the “Noon Buying Rate”) on the relevant Valuation Date or such other
date specified in the applicable pricing supplement. If the Noon Buying Rate is
not announced on that date, the Reference Exchange Rate, Settlement Rate or
other rate for such Reference Currency will be calculated on the basis of the
arithmetic mean of the applicable spot quotations received by the Calculation
Agent at approximately 10:00 a.m., New York City time, on the Valuation
Business Day next succeeding the Valuation Date or such other date specified in
the applicable pricing supplement, for the purchase or sale for deposits in the
reference currency by the New York offices of three leading banks engaged in
the interbank market (selected in the sole discretion of the Calculation Agent)
(the “Reference Banks”). If fewer than three Reference Banks provide 



 4
 









spot quotations, then the Reference Exchange Rate,
Settlement Rate or other rate, as applicable, will be calculated on the basis
of the arithmetic mean of the applicable spot quotations received by the
Calculation Agent at approximately 10:00 a.m., New York City time, on the
relevant date from two Reference Banks (selected in the sole discretion of the
Calculation Agent), for the purchase or sale for deposits in the Reference
Currency. If these spot quotations are available from only one Reference Bank,
then the Calculation Agent, in its sole discretion, will determine whether that
quotation is reasonable to be used. If no spot quotation is available, then the
Reference Exchange Rate, Settlement Rate or other rate, as applicable, for such
Reference Currency will be determined by the Calculation Agent in good faith
and in a commercially reasonable manner.


A “Business Day”,
notwithstanding any provision in the Indenture, is any day that is not is not a
Saturday or Sunday and that is not a day on which banking institutions in New
York City generally are authorized or obligated by law or executive order to be
closed.


The “Calculation Agent” means
Lehman Brothers Inc.


Except as provided below, the
Redemption Amount may, at the option of the Company, be made by check mailed to
the person entitled thereto at such person’s address as it appears on the
registry books of the Company.


Payment of the Redemption
Amount will be made in immediately available funds in accordance with the
normal procedures of the Trustee (or any duly appointed Paying Agent).


The Company will pay any
administrative costs imposed by banks in making payments in immediately
available funds, but any tax, assessment or governmental charge imposed upon
payments hereunder, including, without limitation, any withholding tax, will be
borne by the Holder hereof.


References herein to “U.S.
dollars” or “U.S.$” or “$” or “USD” are to the coin or currency of the United
States as at the time of payment is legal tender for the payment of public and
private debts.


REFERENCE
IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET FORTH ON THE REVERSE
HEREOF.  SUCH FURTHER PROVISIONS SHALL
FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.


This Note shall not be valid or
become obligatory for any purpose until the certificate of authentication
hereon shall have been signed by the Trustee under the Indenture.

LEHMAN BROTHERS
HOLDINGS INC.


MEDIUM-TERM NOTES,
SERIES I


FX BASKET-LINKED NOTE
 DUE APRIL 16, 2008


Section 1.  General.  This Note is one of a duly authorized series
of Notes of the Company designated as the Medium-Term Notes, Series I, FX Basket-Linked Note (herein called
the “Notes”).  The Notes are one of an indefinite
number of series of debt securities of the Company (collectively, the “Securities”)
issued or issuable under and pursuant to an indenture dated as of September 1,
1987, as amended and supplemented (the “Indenture”), duly executed and
delivered by the Company and Citibank, N.A., as Trustee (herein called the “Trustee”),
to which Indenture and all indentures supplemental thereto reference is hereby
made for a description of the rights, limitations of rights, obligations,
duties and immunities thereunder of the Trustee, the Company and the holders of
the Securities.  The separate series of
Securities may be issued in various aggregate principal amounts, may mature at
different times, may bear interest (if any) at different rates, may be subject
to different redemption provisions or repurchase rights (if any), may be
subject to different sinking, purchase or analogous funds (if any), may be
subject to different covenants and Events of Default and may otherwise vary as
in the Indenture provided.


Section 2.  Principal
Amount for Indenture Purposes.  For
the purpose of determining whether Holders of the requisite amount of Notes of
this series outstanding under the Indenture have made a demand, given a notice
or waiver or taken any other action, the principal amount of this Note will be
deemed to be the principal amount of this Note then outstanding.


Section 3.  Modification
and Waivers.  The Indenture contains
provisions permitting the Company and the Trustee, with the consent of the
Holders of not less than 662/3% in aggregate principal amount of each series of
the Securities at the time Outstanding to be affected, evidenced as in the
Indenture provided, to execute supplemental indentures adding any provisions to
or changing in any manner or eliminating any of the provisions of the Indenture
or of any supplemental indenture or modifying in any manner the rights of the
holders of the Securities of all such series; provided, however, that no such
supplemental indenture shall, among other things, (i) change the fixed maturity
of any Security, or reduce the Additional Amount or the principal amount
thereof, or reduce the rate or extend the time of payment of interest thereon
or reduce any premium or other amount payable on redemption, or make the
Additional Amount or the principal amount thereof, premium or other amount
payable, if any, or interest thereon payable in any coin or currency other than
that herein above provided, without the consent of the Holder of each Security
so affected, or (ii) change the place of payment on any Security, or impair the
right to institute suit for payment on any Security, or reduce the aforesaid
percentage of Securities, the holders of which are required to consent to any
such supplemental indenture, without the consent of the holders of each
Security so affected.  It is also
provided in the Indenture that, prior to any declaration accelerating the
maturity of any series of Securities, the holders of a majority in aggregate
principal amount of the Securities of such series Outstanding may on behalf of
the holders of all the Securities of such series waive any past 













default or Event of Default under the Indenture with
respect to such series and its consequences, except a default in the payment of
interest, if any, on the Additional Amount or the principal amount, or premium,
if any, on any of the Securities of such series, or in the payment of any
sinking fund installment or analogous obligation with respect to Securities 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 and owners of this Note and any Notes of this series which
may be issued in exchange or substitution herefor, irrespective of whether or
not any notation thereof is made upon this Note or such other Notes of this
series.


Section 4.  Obligations
Unconditional.  No reference herein
to the Indenture and no provisions of this Note or of the Indenture shall alter
or impair the obligation of the Company, which is absolute and unconditional,
to pay the Additional Amount or the principal amount on this Note at the place,
at the respective times, at the rate, and in the coin or currency herein
prescribed.


Section 5.  Defeasance.  The Indenture contains provisions for the
discharge of the Indenture and defeasance at any time of the indebtedness on
this Note upon compliance by the Company with certain conditions set forth
therein, which provisions apply to this Note.


Section 6.  Authorized
Form and Denominations.  The Notes of
this series are issuable in registered form, without coupons.  Each Note will be issued initially as either
a Global Security or a Certificated Note, at the option of the Company, in
denominations of $1,000 or whole multiples of $1,000, either at the office or
agency to be designated and maintained by the Company for such purpose in the
Borough of Manhattan, New York City, pursuant to the provisions of the
Indenture or at any of such other offices or agencies as may be designated and
maintained by the Company for such purpose pursuant to the provisions of the
Indenture, and in the manner and subject to the limitations provided in the
Indenture, but without the payment of any service charge, except for any tax or
other governmental charges imposed in connection therewith.  Notes of this series are exchangeable for a
like aggregate principal amount of Notes of this series of a different
authorized denomination, except that Global Securities will not be exchangeable
for Certificated Notes of this series.


Section 7.  Registration
of Transfer.  As provided in the
Indenture and subject to certain limitations as 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 Corporate Trust Office or agency in a
Place of Payment for this Note, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security Registrar
requiring such written instrument of transfer duly executed by, the Holder
hereof or his attorney duly authorized in writing, and thereupon one or more
new Notes of this series, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.


If at any time the Depository notifies the Company
that it is unwilling or unable to continue as Depository or if at any time the
Depository shall no longer be eligible under the Indenture, the Company shall
appoint a successor Depository.  If a
successor Depository for the Notes of this series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such ineligibility, the Company will issue, and the Trustee will 













authenticate and deliver, Notes of this series in
definitive form in an aggregate principal amount equal to the principal amount
of this Note.


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 that may be
imposed 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, and neither the Company nor the Trustee nor any agent
of the Company or of the Trustee shall be affected by any notice to the
contrary.


Section 8.  Events
of Default.  If an Event of Default
with respect to Notes of this series shall occur and be continuing, the amount
that may be declared due and payable upon any acceleration of the notes will be
determined by the Calculation Agent for the period from and including the Trade
Date to but excluding the date of early repayment and will equal, for each
note, the Redemption Amount, calculated as though the date of early repayment
were the Maturity Date. If a bankruptcy proceeding is commenced in respect of
Lehman Brothers Holdings, the claim of the beneficial owner of a note for the
period from and including the Trade Date to but excluding the date of early
repayment will be capped at the Redemption Amount, calculated as though the
date of the commencement of the proceeding were the Maturity Date.


Section 9.  No
Recourse Against Certain Persons.  No
recourse for the payment of the Additional Amount or for any claim based hereon
or otherwise in respect hereof, and no recourse under or upon any obligation,
covenant or agreement of the Company in the Indenture or any Indenture
supplemental thereto or in any Note, or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator,
stockholder, officer or director, as such, past, present or future, of the
Company or of any successor corporation, either directly or through the Company
or any successor corporation, whether by virtue of any constitution, statute or
rule of law or by the enforcement of any assessment or penalty or otherwise,
all such liability being, by the acceptance hereof and as part of the
consideration for the issue hereof, expressly waived and released.


Section 10.  Defined
Terms.  All terms used but not
defined in this Note are used herein as defined in the Indenture.


Section 11.  GOVERNING LAW.  THIS NOTE SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
