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 23, 2010, 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 450%.

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 0.5228 and the denominator of which is the Settlement Rate for BRL plus

(ii) a quotient, the numerator of which is 6.5575 and the denominator of which is the Settlement Rate for RUB plus

(iii) a quotient, the numerator of which is 11.0225 and the denominator of which is the Settlement Rate for INR plus

(iv) a quotient, the numerator of which is 1.9352 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 February 16, 2007.

The “Valuation Date” is February 16, 2010; 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:

3

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.

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.

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

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 maturity and Valuation Date of the notes were the date of the commencement of the proceeding.
