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 Notes do not bear interest. No payments on the Notes will be made until the Maturity Date.

The “Maturity Date” is April 20, 2007, or if such day is not a Business Day, on the next following Business Day.

The Redemption Amount, for each $1 principal amount of the Notes represented hereby, is the amount equal to the sum of (i) the Principal Protection times $1 plus (ii) the Additional Amount.

The “Principal Protection” is 97.0%.

The “Additional Amount”, for each $1 principal amount of the Notes represented hereby is equal to (subject to the occurrence of a Disruption Event) $1 multiplied by:

•                  21%, if the Settlement Rate is less than or equal to the Reference Level; or

•                  0%, if the Settlement Rate is greater than the Reference Level.

The “Settlement Rate” for the Reference Currency is the Reference Exchange Rate on the Valuation Date, observed as per the Settlement Rate Option (subject to the occurrence of a Price Source Unavailability Event).

The “Reference Level” is 1.3505.

The “Reference Currency” is the Turkish Lira (TRY).

The “Reference Exchange Rate” is the spot exchange rate for the Reference Currency quoted against the U.S. dollar expressed as the number of units of the Reference Currency per USD 1.

The “Settlement Rate Option” for the Reference Currency is as follows:

The screen or time of observation indicated in relation to the 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.

2

The “Valuation Date” is April 16, 2007 or, if such day is not a Valuation Business Day, the immediately preceding Valuation Business day.

A “Valuation Business Day” means any day on which the Trans-European Automated Real-Time Gross Settlement Express Transfer (TARGET) System is open.

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.

Upon the occurrence of a Disruption Event with respect to any Reference Currency on any day during the term of the notes, the Calculation Agent shall determine the Additional Amount payable on the Maturity Date in good faith and in a commercially reasonable manner.

A “Disruption Event” means any of the following events (other than a Price Source Unavailability Event), 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 (i) the conversion of TRY into USD through customary legal channels or (ii) the delivery of (x) USD from accounts inside Turkey to accounts outside Turkey or (y) of TRY between accounts inside Turkey or to a party that is a non-resident of Turkey;

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

(C)                                the occurrence and/or existence of any event (other than those set forth in (A) or (B) above or those constituting a Price Source Unavailability Event) with respect to the Reference Currency that prevents or makes impossible (x) the Calculation Agent’s ability to calculate the Additional Amount, (y) the fulfilment of the obligations of the Company under the notes, or (z) the ability of the Company or of any of its affiliates through which the Company hedges its position under the notes to hedge such position or to unwind all or a material portion of such hedge.

Upon the occurrence of a Price Source Unavailability Event with respect to a Reference Currency, the Settlement Rate for the Reference Currency will be determined in accordance with the Fallback Rate Observation Methodology.

A “Price Source Unavailability Event” means, as determined in good faith by the Calculation Agent, the Settlement Rate being unavailable for the Reference Currency, or the occurrence of an event (other than an event constituting a Disruption Event) that generally makes it impossible to obtain the Settlement Rate for the Reference Currency, on the Valuation Date.

The “Fallback Rate Observation Methodology” means that the Settlement Rate for the 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, 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 Settlement Rate 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,

3

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 Settlement Rate for such Reference Currency will be determined by the Calculation Agent in good faith and in a commercially reasonable manner.

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 upon surrender of this Note at the corporate trust office or agency of the Trustee (or any duly appointed Paying Agent) maintained for that purpose in the Borough of Manhattan, New York City (the “Corporate Trust Office”), provided that this Note is presented to the Trustee (or any such Paying Agent) in time for the Trustee (or any such Paying Agent) to make such payments in such funds in accordance with its normal procedures.

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 “USD”, “U.S. dollars” or “U.S.$” or “$” 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.

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 Redemption 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 Redemption 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 hereinabove 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 Redemption 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 Redemption 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.

Each Note will be issued initially as either a Global Security or a Certificated Note, at the option of the Company, in denominations of $10,000 or whole multiples of $5,000, 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.

Section 8. Events of Default. If an Event of Default with respect to Notes of this series shall occur and be continuing, the amount declared due and payable upon any acceleration of the Notes will be determined by the Calculation Agent and will equal the Redemption Amount calculated as though the maturity of the Notes were the date of early repayment in the manner and with the effect provided in the Indenture. The amount payable to the Holder hereof upon any acceleration permitted under the Indenture will be equal to the Redemption Amount calculated as though the date to which the maturity has been accelerated were the Maturity Date as determined by the Calculation Agent.
