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 February 1, 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:


(A) 0.0%, if the Basket Return is less than or equal to 0.0; or


(B) 4.5%, if the Basket Return is greater than 0.0.


The “Reference Currencies” are the Indian Rupee (INR) and Indonesian
Rupiah (IDR).


The
“Basket Return” equals the sum of the Weighted Currency Returns.


The “Weighted
Currency Return” for each Reference Currency is the product of the Weighting
for such Reference Currency times a quotient, the numerator of which is the
difference of the Initial Reference Currency Rate for such Reference Currency
minus the Settlement Rate for such Reference Currency and the denominator of
which is the Initial Reference Currency Rate for such Reference Currency.


The “Weighting”
and “Initial Reference Currency Rate” for each Reference Currency are as
follows:


	
  Reference 

  Currency

  	
  Weighting

  	
  Initial 

  Reference

  Currency Rate

  
	
  IDR

  	
  50.00%

  	
  9195

  
	
  INR

  	
  50.00%

  	
  40.42

  



 


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


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 “Valuation Date” is January 28, 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).









 3



The “Issue Date” is August 2, 2007.


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
Return 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









 4



(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:


	
  Reference Currency

  	
  Screen Reference

  	
  Valuation Business Day

  
	
  INR

  	
  RBIB

  	
  Mumbai

  
	
  IDR

  	
  ABSIRFIX01

  	
  Singapore

  



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 on the Valuation Date or such other relevant date.   
The Settlement Rate Option for the IDR is the Indonesian Rupiah/U.S.
dollar spot rate at 11:00 a.m., Singapore time, expressed as the amount of
Indonesian Rupiah per one U.S. dollar, for settlement in two Business Days
reported by the Association of Banks in Singapore which appears on the Reuters
Page ABSIRFIX01 to the right of the caption “Spot” under the column “IDR” at
approximately 11:30 a.m., Singapore time, on the 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 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

Except as provided below,
the Redemption Amount may, at the option of the Company, be made by check

MEDIUM-TERM NOTES,
SERIES I


FX BASKET-LINKED NOTE
 DUE FEBRUARY 1, 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 66-2/3% 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 Issue
Date to but excluding the date of early repayment and will equal, for each
note, the Redemption Amount, calculated as 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 Issue 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.
