SUMMARY INFORMATION — Q&A

This summary highlights selected information from this pricing supplement, the MTN prospectus supplement and the base prospectus to help you understand the notes. You should carefully read this pricing supplement, the MTN prospectus supplement and the base prospectus to understand fully the terms of the notes and the tax and other considerations that are important to you in making a decision about whether to invest in the notes. You should pay special attention to the “Risk Factors” section on page S-4 of the MTN prospectus supplement to determine whether an investment in the notes is appropriate for you.

What are the notes?

The notes will be a series of our senior debt that are linked to a basket (the “Basket”) that measures the performance of the South Korean Won (KRW), Indonesian Rupiah (IDR), Indian Rupee (INR), Malaysian Ringgit (MYR) and Singapore Dollar (SGD) relative to the U.S. dollar (USD).  We refer to KRW, IDR, INR, MYR and SGD as the Reference Currencies. Each of KRW, IDR, INR, MYR and SGD makes up a portion of the Basket with a weighting, on the date of this pricing supplement, of 20%.

The notes will rank equally with all other unsecured debt of Lehman Brothers Holdings Inc., except subordinated debt, and will mature on February 19, 2010 (or if such day is not a New York business day, the next succeeding New York business day).

What payments will I receive on the notes before maturity?

None. Unlike ordinary debt securities, the notes do not pay interest before maturity.

What will I receive if I hold the notes until the stated maturity date?

We have designed this type of note for investors who want to protect their investment by receiving at least the principal amount of their investment at maturity and who also want to participate in a possible increase in the value of the Reference Currencies relative to the U.S. dollar. At maturity, you will receive a payment equal to the sum of:

·the principal amount of the notes; and

·the Additional Amount, if any.

As a result, if you hold the notes until maturity, you will not receive less than the principal amount.

How will the Additional Amount be calculated?

The Additional Amount is a single U.S. dollar amount equal to the principal amount of the notes multiplied by the product of the Leverage times the Basket Return; provided that the minimum Additional Amount payable on the notes shall be zero.

The Basket Return is the sum of the Weighted Currency Returns for the Reference Currencies. 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 Initial Reference Currency Rate for each Reference Currency is as follows:

Currency	Initial Reference Currency  Rate
KRW	945.4
IDR	9268
INR	39.68
MYR	3.2340
SGD	1.4163

The Initial Reference Currency Rate for each Reference Currency is the Reference Exchange Rate for that Reference Currency determined by the Calculation Agent on the date hereof in accordance with the applicable Settlement Rate Option (as defined in “Description of the Notes” below).

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

The Valuation Date is February 12, 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 “Description of the Notes” below).

The Reference Exchange Rates are the spot exchange rate for each of the Reference Currencies quoted against the U.S. dollar expressed as the number units of the Reference Currency per one USD.

PS-1

The Leverage is 260%.

For further information concerning the calculation of the Additional Amount, see “Description of the Notes” below.  You can review hypothetical Redemption Amount payment examples under “Description of the Notes—Hypothetical Redemption Amount Payment Examples” below.

How will I be able to find the Basket Return at any point in time?

You can obtain the Basket Return at any time by calling your Lehman Brothers sales representative.

You can review the historical performance of the South Korean Won, Indonesian Rupiah, Indian Rupee, Malaysian Ringgit and Singapore Dollar under “Exchange Rates” below.

Are there any risks associated with my investment?

Yes, the notes will be subject to a number of risks. See “Risk Factors” beginning on page S-4 of the MTN prospectus supplement.

What about taxes?

We intend to treat the notes as contingent payment debt instruments as described under “Certain United States Federal Income Tax Consequences” below and “Supplemental United States Federal Income Tax Consequences—Contingent Payment Debt Instruments” in the MTN prospectus supplement.

What happens in the event of a Disruption Event?

If the Calculation Agent determines that a Disruption Event (as defined in “Description of the Notes” below) 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 the Fallback Rate Observation Methodology, as defined under “Description of the Notes—Currency-Indexed Notes” in the MTN prospectus supplement.

Who is Lehman Brothers Holdings?

Lehman Brothers Holdings Inc. and its subsidiaries (collectively “Lehman Brothers Holdings”) an innovator in global finance, serves the financial needs of corporations, governments and municipalities, institutional clients and high-net-worth clients worldwide. Lehman Brothers Holdings’ worldwide headquarters in New York and regional headquarters in London and Tokyo are complemented by offices in additional locations in North America, Europe, the Middle East, Latin America and the Asia Pacific region. See “Prospectus Summary—Lehman Brothers Holdings Inc.” and “Where You Can Find More Information” on pages 1 and 58, respectively, of the base prospectus.

You may request a copy of any document Lehman Brothers Holdings files with the Securities and Exchange Commission, or the SEC, pursuant to the Securities and Exchange Act of 1934, at no cost, by writing or telephoning Lehman Brothers Holdings at the address set forth under the caption “Where You Can Find More Information” in the base prospectus.

What is the role of Lehman Brothers Inc.?

Lehman Brothers Inc., one of our subsidiaries, will be the agent and the calculation agent for purposes of determining whether the Additional Amount is payable on the Maturity Date as well as determining whether a Disruption Event has occurred.  Potential conflicts of interest may exist between Lehman Brothers Inc. and you as a beneficial owner of the notes. See “Risk Factors—An affiliate of ours may act as calculation agent on the notes, creating a potential conflict of interest between you and us” in the MTN prospectus supplement and “Description of the Notes” below.

Can you tell me more about the effect of hedging activity by Lehman Brothers Holdings?

We expect to hedge our obligations under the notes through one or more of our affiliates. This hedging activity will likely involve trading in the Reference Currencies or in other instruments, such as options, swaps or futures, based on the Reference Currencies.

PS-2

This hedging activity could adversely affect the price at which your notes will trade in the secondary market. Moreover, this hedging activity may result in us or our affiliates receiving a profit, even if the market value of the notes declines.

In what form will the notes be issued?

The notes of each series will be represented by one or more global securities that will be deposited with and registered in the name of The Depository Trust Company or its nominee. Except in very limited circumstances you will not receive a certificate for your notes.

Will the notes be listed on a stock exchange?

No, the notes will not be listed on a stock exchange.

After the initial offering of the notes, Lehman Brothers Inc. intends to make a market in the notes and may stabilize or maintain the market price of the notes during the initial distribution of the notes.  However, Lehman Brothers Inc. will not be obligated to engage in any of these market activities or to continue them once they are begun. No assurance can be given as to the liquidity of the trading market for the notes.

PS-3

RISK FACTORS

An investment in the notes entails certain risks not associated with an investment in conventional floating rate or fixed rate medium-term notes. See “Risk Factors” generally, and “Risk Factors—Risks Relating to Currency-Indexed Notes” specifically, in the MTN prospectus supplement.

DESCRIPTION OF THE NOTES

The U.S.$3,975,000 aggregate principal amount of FX Basket-Linked Notes Due February 19, 2010 offered hereby are Medium-Term Notes, Series I, of Lehman Brothers Holdings Inc.  The CUSIP number for the notes is 5252M0CE5 and the ISIN number is US5252M0CE53. The notes will be issued in book-entry form only, and will be eligible for transfer through the facilities of DTC or any successor depository. See “Book-Entry Procedures and Settlement” in the base prospectus.

The notes will be issued in minimum denominations of U.S.$1,000 and in integral multiples of U.S.$1,000 in excess thereof, and will have a stated “Maturity Date” of February 19, 2010 or if such day is not a New York business day, the next succeeding New York business day.

The notes are offered as foreign exchange-linked notes with portions of the amount payable at the Maturity Date indexed to the spot exchange rates of a basket of five currencies consisting of the South Korean Won (KRW), Indonesian Rupiah (IDR), Indian Rupee (INR), Malaysian Ringgit (MYR) and Singapore Dollar (SGD). Each of the KRW, IDR, INR, MYR and SGD (each a “Reference Currency” and, collectively, the “Reference Currencies”) makes up a portion of the “Basket” with a weighting, on the date of this pricing supplement, of 20%.

If held to the Maturity Date, holders of the notes will receive on the Maturity Date a single payment in U.S. dollars in an amount equal to the Redemption Amount as described below. No interest will accrue during the term of the notes and no interest will be payable on the Maturity Date except in the event that the Redemption Amount is not paid when due, as described below.

The “Redemption Amount” for each note will be an amount equal to the sum of the principal amount of each note plus the Additional Amount, if any.  The Additional Amount is linked to the Basket Return, which in turn is based on the spot exchange rates of the Reference Currencies relative to the U.S. dollar. Holders of the notes will receive on the Maturity Date an amount equal to not less than the principal amount of each note, notwithstanding a possible depreciation of the Reference Currencies as compared to the U.S. dollar.

The “Additional Amount” is a single U.S. dollar amount equal to the principal amount of the notes multiplied by the product of the Leverage times the Basket Return; provided that the minimum Additional Amount payable on the notes shall be zero.

The “Basket Return” is the sum of the Weighted Currency Returns for the Reference Currencies. 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 “Leverage” is 260%.

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

Currency	Weighting	Initial Reference Currency Rate
KRW	20%	945.4
IDR	20%	9268
INR	20%	39.68
MYR	20%	3.2340
SGD	20%	1.4163

The Initial Reference Currency Rate for each Reference Currency is the Reference Exchange Rate for that Reference Currency determined by the Calculation Agent on the Original Trade Date in accordance with the applicable Settlement Rate Option.

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 “Valuation Date” is February 12, 2010; provided that, upon the occurrence of a Disruption Event with

PS-4

respect to a Reference Currency, the Valuation Date for the affected Reference Currency may be postponed (as described below).

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 one USD.

The “Upsize Trade Date” is February 14, 2008 ($1,975,000 aggregate principal amount).

The “Original Trade Date” is February 13, 2008 ($2,000,000 aggregate principal amount).

The “Issue Date” is February 20, 2008.

The “Settlement Rate Option” and “Valuation Business Day” for each Reference Currency are as follows:

Reference  Currency	Screen Reference	Valuation  Business Day
KRW	KFTC18	Seoul
IDR	ABSIRFIX01	Singapore
INR	RBIB	Mumbai
MYR	ABSIRFIX01	Singapore
SGD	ABSIRFIX01	Singapore

For further information concerning the Settlement Rate Option and Valuation Business Day, see “Description of the Notes—Currency-Indexed Notes” in, and Appendix A to, the MTN prospectus supplement. The spot exchange rate for each of the Reference Currencies quoted against the U.S. dollar expressed as number of units of the Reference Currency per one USD.

If 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 the Fallback Rate Observation Methodology, as defined under “Description of the Notes—Currency-Indexed Notes” in the MTN prospectus supplement.

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 (x) 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, or (y) the conversion of SGD into USD through customary legal channels;
(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.

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.

The notes are not subject to redemption at our option or to repayment at the option of the Holders of the notes prior to the Maturity Date.

In case an event of default (as described in the base prospectus) with respect to any note shall have occurred 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 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 Issue Date to but excluding the date of early repayment will be capped

PS-5

at the Redemption Amount, calculated as though the date of the commencement of the proceeding were the Maturity Date.

Any overdue payment in respect of any note will bear interest until the date upon which all sums due in respect of such note are received by or on behalf of the relevant Holder, at the rate per annum that is the rate for deposits in U.S. dollars for a period of six months that appears on the Reuters Screen LIBOR page as of 11:00 a.m. (London time) on the first London business day following such failure to pay. Such rate will be determined by the Calculation Agent.  If interest in respect of overdue amounts is calculated for a period of less than one year, it will be calculated on the basis of a 360-day year consisting of 12 months of 30 days each, and, in the case of an incomplete month, the number of days elapsed.

The “Calculation Agent” means Lehman Brothers Inc.

PS-6

Hypothetical Redemption Amount Payment Examples

The following payment examples for this note show scenarios for the Redemption Amount payable at maturity of the notes, including scenarios under which an Additional Amount will or will not be payable, based on the Leverage of 260% and the Initial Reference Currency Rates for the Reference Currencies (each of which were determined on the Original Trade Date), as well as hypothetical values for the Settlement Rates (which will be determined on the Valuation Date) and the resulting Basket Return.

The Settlement Rate values for the Reference Currencies have been chosen arbitrarily for the purpose of these examples, are not associated with Lehman Brothers Research forecasts for any Reference Currency/USD exchange rates and should not be taken as indicative of the future performance of any Reference Currency/USD exchange rate.

PS-7

Example 1: KRW, IDR, INR, MYR and SGD each appreciate relative to their Initial Reference Currency Rates, resulting in a Basket Return of 0.0820 (8.20%).  The Additional Amount is therefore equal to 21.32%, and the Redemption Amount is equal to 121.32%, times the principal amount of the notes.

Because the Basket Return is 0.0820, the Redemption Amount payable at maturity is equal to $1,213.20 per $1,000 note (reflecting an Additional Amount of $213.20 per note), calculated as follows:

Redemption Amount = $1,000 + ($1,000 * 260% * 0.0820) = $1,213.20

The table below illustrates how the Basket Return in the above example was calculated:

Reference Currency	Initial Reference Currency Rate (on Original Trade Date)	Weighting	Settlement Rate (on Valuation Date)	Weighted Currency Return
KRW	945.4	20%	879.2	0.0140
IDR	9268	20%	8527	0.0160
INR	39.68	20%	35.32	0.0220
MYR	3.2340	20%	3.0400	0.0120
SGD	1.4163	20%	1.2888	0.0180
	Basket Return = Sum of Weighted Currency Returns =			0.0820

Example 2: KRW, IDR, INR, MYR and SGD each depreciate relative to their Initial Reference Currency Rates, resulting in a Basket Return of –0.0562 (–5.62%), which is less than zero.  The Additional Amount is therefore 0%, and the Redemption Amount is equal to the product of 100%, times the principal amount of the notes.

Because the Basket Return is –0.0562, which is less than zero, the Redemption Amount payable at maturity is equal to $1,000 per $1,000 note (reflecting an Additional Amount of $0 per note), the repayment of principal invested, with no additional return.

The table below illustrates how the Basket Return in the above example was calculated:

Reference Currency	Initial Reference Currency Rate (on Original Trade Date)	Weighting	Settlement Rate (on Valuation Date)	Weighted Currency Return
KRW	945.4	20%	985.1	–0.0084
IDR	9268	20%	9463	–0.0042
INR	39.68	20%	41.90	–0.0112
MYR	3.2340	20%	3.4895	–0.0158
SGD	1.4163	20%	1.5339	–0.0166
	Basket Return = Sum of Weighted Currency Returns =			–0.0562

PS-8

Example 3: KRW and IDR each appreciate relative to their Initial Reference Currency Rates while INR, MYR and SGD each depreciate relative to their Initial Reference Currency Rates, resulting in a Basket Return of 0.0150 (1.50%).  The Additional Amount is therefore equal to 3.90%, and the Redemption Amount is equal to 103.90%, times the principal amount of the notes.

Because the Basket Return is 0.0150, the Redemption Amount payable at maturity is equal to $1,039.00 per $1,000 note (reflecting an Additional Amount of $39.00 per note), calculated as follows:

Redemption Amount = $1,000 + ($1,000 * 260% * 0.0150) = $1,039.00.

The table below illustrates how the Basket Return in the above example was calculated:

Reference Currency	Initial Reference Currency Rate (on Original Trade Date)	Weighting	Settlement Rate (on Valuation Date)	Weighted Currency Return
KRW	945.4	20%	849.0	0.0204
IDR	9268	20%	8489	0.0168
INR	39.68	20%	40.63	–0.0048
MYR	3.2340	20%	3.3537	–0.0074
SGD	1.4163	20%	1.4871	–0.0100
	Basket Return = Sum of Weighted Currency Returns =			0.0150

Example 4: KRW, INR and SGD each depreciate relative to their Initial Reference Currency Rates while IDR and MYR each appreciate relative to their Initial Reference Currency Rates, resulting in a Basket Return of –0.0272 (–2.72%).  The Additional Amount is therefore equal to 0%, and the Redemption Amount is equal to 100%, times the principal amount of the notes.

Because the Basket Return is –0.0272, which is less than zero, the Redemption Amount payable at maturity is equal to $1,000 per $1,000 note (reflecting an Additional Amount of $0 per note), the repayment of principal invested, with no additional return.

The table below illustrates how the Basket Return in the above example was calculated:

Reference Currency	Initial Reference Currency Rate (on Original Trade Date)	Weighting	Settlement Rate (on Valuation Date)	Weighted Currency Return
KRW	945.4	20%	1080.6	–0.0286
IDR	9268	20%	8971	0.0064
INR	39.68	20%	45.75	–0.0306
MYR	3.2340	20%	2.7230	0.0316
SGD	1.4163	20%	1.4588	–0.0060
	Basket Return = Sum of Weighted Currency Returns =			–0.0272

HISTORICAL EXCHANGE RATES

General

The notes are designed to allow investors to participate in spot exchange rate movements of the Reference Currencies relative to the U.S. dollar. The Reference Currencies consist of the South Korean Won (KRW), Indonesian Rupiah (IDR), Indian Rupee (INR), Malaysian Ringgit (MYR) and Singapore Dollar (SGD), each of which makes up a portion of the Basket with a weighting of 20%.

Historical Data on the Reference Currencies

The following chart shows the spot exchange rates for each Reference Currency at the end of each week in the period from the week ending February 13, 2005 through the week ending February 10, 2008 using historical data obtained from Reuters; neither Lehman Brothers Inc. nor Lehman Brothers Holdings Inc. makes any representation or warranty as to the accuracy or completeness of this data.  The spot exchange rates are expressed as the amount of U.S. dollars per Reference Currency to show the appreciation or depreciation, as the case may be, of the Reference Currency against the U.S. dollar.  The spot exchange rates used to calculate the Basket Return are expressed as the amount of Reference Currency per U.S. dollar, which are the inverse of the spot exchange rates presented in the following charts.  The historical data on each Reference Currency is not necessarily indicative of the future performance of the Reference Currencies, the Basket Return or what the value of the notes may be. Fluctuations in exchange rates make it difficult to predict whether the Additional Amount will be payable at maturity, or what that Additional Amount, if any, may be.  Historical exchange rate fluctuations may be greater or lesser than those experienced by the holders of the notes.

Hypothetical Historical Basket Return

The following charts show the hypothetical Basket Return at the end of each week in the period from the week ending February 13, 2005 through the week ending February 10, 2008, and February 13, 2008, based on the hypothetical composite performance of the Reference Currencies using data obtained from Reuters; neither Lehman Brothers Inc. nor Lehman Brothers Holdings Inc. makes any representation or warranty as to the accuracy or completeness of this data.  The Basket Return was indexed to a level of 0.0 on the Original Trade Date based upon the Initial Reference Exchange Rates determined on that day.  The composite value of the Reference Currencies on any prior day was obtained by using the calculation of the Basket Return described above. Spot exchange rates used in this determination are expressed as the number of units of Reference Currency per U.S. dollar.

We have agreed to sell to Lehman Brothers Inc. (the “Agent”), and the Agent has agreed to purchase from us, the principal amount of the notes at the price specified on the cover of this pricing supplement. The Agent is committed to take and pay for all of the notes, if any are taken.

The Agent proposes to offer the notes initially at a public offering price equal to the public offering price on the cover of this pricing supplement and to certain dealers at a discount not to exceed 1.0%. After the initial public offering, the public offering price and the selling terms may from time to time be varied by the Agent.

It is expected that delivery of the notes will be made against payment therefor more than three business days following the date of this pricing supplement. Trades in the secondary market generally are required to settle in three business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the securities on any day prior to the third business day before the settlement date will be required to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement.

If the notes are sold in a market-making transaction after their initial sale, information about the purchase price and the date of the sale wil l be provided in a separate confirmation of sale.
