Summary Description

The notes are designed for investors who seek exposure to a foreign equity index (the “Equity Component”) as well as certain foreign currencies (the “Currency Component”) related to the Equity Component.

• The Equity Component consists of the S&P BRIC 40^® Index (SBR) (the “Basket Index”).

• The Currency Component consists of the Brazilian real (BRL), the Russian ruble (RUB) and the Indian rupee (INR) (each, a “Basket Currency” and, collectively, the “Basket Currencies”). The Basket Currencies are substantially equally-weighted.

The Equity Component represents 45% of the Basket and the Currency Component constitutes 55% of the Basket. The Notes give investors the opportunity to gain enhanced exposure to the return of a foreign index and the appreciation of foreign currencies against the USD, while providing principal protection if held to maturity.

If the Basket Return is greater than zero on the Valuation Date, the investor will receive a single payment at maturity equal to the principal amount of the notes plus an Additional Amount equal to the principal amount of the notes multiplied by the Basket Return multiplied by the Participation Rate. If the Basket Return on the Valuation Date is less than, or equal to, zero, then the investor will receive at maturity the principal amount of the notes. The notes do not bear interest and are 100% principal protected only if held to maturity.

A “Disruption Event” means, for the Basket Index, a market disruption event (as defined under “Description of Notes—Market Disruption Events” in the accompanying product supplement no. 570-I) and, for a Basket Currency, a Currency Disruption Event. A “Currency 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 Basket Currency is the lawful currency (such jurisdiction with respect to such Basket Currency, the “Basket Currency Jurisdiction”) to accounts outside that Basket Currency Jurisdiction; (B)        the occurrence of any event causing the Reference Exchange Rate for any Basket Currency to be split into dual or multiple currency exchange rates; or (C)        a Reference Exchange Rate being unavailable, or the occurrence and/or existence of any event (other than those set forth in (A) or (B) above) that (i) materially disrupts the market for a Basket Currency or (ii) makes it generally impossible to obtain a Reference Exchange Rate for a Basket Currency on the scheduled Valuation Date. For purposes of the above, “scheduled Index Trading Day” or “scheduled Currency Valuation Business Day” means a day that is or, in the judgment of the Calculation Agent, should have been, an Index Trading Day or a Currency Valuation Business Day.

ADDITIONAL TERMS SPECIFIC TO THE NOTES

Lehman Brothers Holdings Inc. has filed a registration statement (including a base prospectus) with the U.S. Securities and Exchange Commission, or SEC, for this offering. Before you invest, you should read this term sheet together with the base prospectus, as supplemented by the MTN prospectus supplement relating to our Series I medium-term notes of which the notes are a part, and the more detailed information contained in product supplement no. 570-I (which supplements the description of the general terms of the notes) and underlying supplement no. 1160 (which describes the Index, including risk factors specific to it). Buyers should rely upon the base prospectus, the MTN prospectus supplement, product supplement no. 570-I, underlying supplement no. 1160, this term sheet and any other relevant terms supplement for complete details. This term sheet, together with the documents listed below, contains the terms of the notes and supersedes all prior or contemporaneous communications concerning the notes. To the extent that there are any inconsistencies among the documents listed below, this term sheet shall supersede product supplement no. 570-I, which shall, likewise, supersede the base prospectus and the MTN prospectus supplement. You should carefully consider, among other things, the matters set forth in “Risk Factors” in the accompanying product supplement no. 570-I and “Risk Factors” in the accompanying underlying supplement no. 1160, as the notes involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the notes. You may get these documents and other documents Lehman Brothers Holdings Inc. has filed for free by searching the SEC online database (EDGAR^®) at www.sec.gov, with “Lehman Brothers Holdings Inc.” as a search term or through the links below, or by calling Lehman Brothers Inc. toll-free at 1-888-603-5847.

You may access these documents on the SEC website at www.sec.gov as follows (or if such address has changed, by reviewing our filings for the relevant date on the SEC website):

Selected Purchase Considerations

• Uncapped Appreciation Potential:    The notes provide the opportunity to enhance equity/currency returns by multiplying a positive Basket Return by a Participation Rate of 110% to 120%. The notes are not subject to a predetermined maximum gain and, accordingly, any return at maturity will be determined by the appreciation of the Basket. Because the notes are our senior obligations, payment of any amount at maturity is subject to our ability to pay our obligations as they become due.

• Diversification Among the Basket Components:    The return on an investment in the notes linked to the return of the S&P BRIC 40^® Index and the appreciation of the Brazilian real, the Russian ruble and the Indian rupee against the U.S. dollar. The S&P BRIC 40^® Index consists of 40 companies from the emerging markets of Brazil, Russia, India and China. For additional information about the Basket Index, see the information set forth under “The S&P BRIC 40^® Index” in the accompanying underlying supplement no. 1160. For a discussion of risks relating to Currency-Indexed notes, see pages S-8 to S-10 in the accompanying MTN prospectus supplement.

TS-1

• Certain U.S. Federal Income Tax Consequences:    Lehman Brothers Holdings Inc. intends to treat, and by purchasing a note, for all tax purposes, you agree to treat, a note as debt subject to the contingent payment debt instrument rules. Lehman Brothers Holdings Inc. is required to provide the comparable yield to you and, solely for tax purposes, is also required to provide a projected payment schedule that includes the fixed payments on the notes and estimates of the amount and timing of the contingent payments on the notes. Lehman Brothers Holdings Inc. has determined that the comparable yield will be an annual rate of [    ], compounded semi-annually. Based on the comparable yield, the projected payment schedule per $1,000, note is [    ] due at maturity.

Lehman Brothers Holdings Inc. agrees and, by purchasing a note, you agree, for United States federal income tax purposes, to be bound by Lehman Brothers Holdings Inc.’s determination of the comparable yield and projected payment schedule. As a consequence, for United States federal income tax purposes, you must use the comparable yield determined by Lehman Brothers Holdings Inc. and the projected payments set forth in the projected payment schedule prepared by Lehman Brothers Holdings Inc. in determining your interest accruals (even though you will not receive any periodic payments of interest on the notes), and the adjustments thereto, in respect of the notes. See “Certain U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 570-I.

Selected Risk Factors

An investment in the notes involves significant risks. Investing in the notes is not equivalent to investing directly in any of the stocks included in the Basket Index. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement no. 570-I, in the “Risk Factors” section of the accompanying underlying supplement no. 1160 and in the “Risk Factors” section of the MTN prospectus supplement. You should reach an investment decision only after you have carefully considered with your advisors the suitability of an investment in the notes in light of your particular circumstances.

• The Basket Index and Basket Currencies Are Not Equally Weighted:    The Basket is composed of an Equity Component and a Currency Component, which are not equally weighted. Additionally, the Equity Component is comprised of only one Basket Index while the Currency Component is comprised of three Basket Currencies that are weighted equally to each other but weighted different from the Basket Index. One consequence of such unequal weighting is that the same percentage change in the Basket Index would have a greater effect on the Basket Closing Level than such percentage change in one of the Basket Currencies, which have a smaller weighting.

• Changes in the Level of the Basket Components May Offset Each Other:    The Basket is composed of one Basket Index and three Basket Currencies. At a time when the level or rate of the Basket Index or one or more of the Basket Currencies increases, the level or rate of the other Basket components may not increase or may even decline. Therefore, in calculating the Ending Basket Level, increases in the level or rate of the Basket Index or one or more of the Basket Currencies may be moderated, or more than offset, by lesser increases or declines in the level or rate of the other Basket components.

• No Interest or Dividend Payments or Voting Rights:    As a holder of the notes, you will not receive interest payments, and you will not have voting rights or rights to receive cash dividends or other distributions or other rights that holders of stocks included in the Basket Index would have.

• Certain Built-in Costs are Likely to Adversely Affect the Value of the Notes Prior to Maturity:     The original issue price of the notes includes the agent’s commission and the cost of hedging our obligations under the notes through one or more of our affiliates, which includes our affiliates’ expected cost of providing such hedge as well as the profit our affiliates expect to realize in consideration for assuming the risks inherent in providing such hedge. As a result, the price, if any, at which Lehman Brothers Inc. will be willing to purchase notes from you in secondary market transactions, if at all, will likely be lower than the original issue price and any sale prior to the maturity

TS-2

date could result in a substantial loss to you. The notes are not designed to be short-term trading instruments. YOU SHOULD BE WILLING TO HOLD YOUR NOTES TO MATURITY.

• Dealer Incentives:    We and our affiliates act in various capacities with respect to the notes. Lehman Brothers Inc. and other of our affiliates may act as a principal, agent or dealer in connection with the notes. Such affiliates, including the sales representatives, will derive compensation from the distribution of the notes and such compensation may serve as an incentive to sell these notes instead of other investments.

• Lack of Liquidity:    The notes will not be listed on any securities exchange. Lehman Brothers Inc. intends to offer to purchase the notes in the secondary market but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily. Because other dealers are not likely to make a secondary market for the notes, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which Lehman Brothers Inc. is willing to buy the notes.

• Potential Conflicts:    We and our affiliates play a variety of roles in connection with the issuance of the notes, including acting as Calculation Agent and hedging our obligations under the notes. In performing these duties, the economic interests of the Calculation Agent and other affiliates of ours are potentially adverse to your interests as an investor in the notes.

• You Must Rely on Your Own Evaluation of the Merits of an Investment in the Notes:    In the ordinary course of their businesses Lehman Brothers Holdings Inc., or its respective affiliates, may from time to time express views on expected movements in the level of the Basket Index and/or rates of the Basket Currencies. These views are sometimes communicated to clients who are active participants in the equity and/or currency markets. However, these views, depending upon worldwide economic, political and other developments, may vary over differing time horizons, may be inconsistent with the investment view implied in the notes and are subject to change. In connection with your purchase of the notes, you should investigate the equity and currency markets and not rely on views which may be expressed by Lehman Brothers Holdings Inc. or its affiliates in the ordinary course of their businesses with respect to the future performance of the Equity Component and the Currency Component.

• Many Economic and Market Factors Will Impact the Value of the Notes:    In addition to the level of the Basket on any day, the value of the notes will be affected by a number of economic and market factors that may either offset or magnify each other and which are set out in more detail in the product supplement no. 570-I.

• Creditworthiness of Issuer:    An investment in the notes will be subject to the credit risk of Lehman Brothers Holdings, Inc., and the actual and perceived creditworthiness of Lehman Brothers Holdings Inc. may affect the market value of the notes.

• Tax Treatment:    You should consider the tax consequences of investing in the notes and you should consult your own tax advisor about your own tax situation before investing in the notes.

Hypothetical Payment at Maturity for Each USD1,000 Principal Amount Note

The following table illustrates the hypothetical payment amount at maturity, for a hypothetical range of performance of the Basket for a Basket Return of -100% to 50% and reflects a Starting Basket Level of 1,000 and assumes a Participation Rate of 115% (the midpoint of the range of 110% to 120%, the actual Participation Rate will be determined on the Trade Date). The hypothetical payment at maturity examples set forth below are for illustrative purposes only, have been chosen arbitrarily for the purposes of these examples, are not associated with Lehman Brothers Research forecasts for the Equity Component or Currency Component and may not be indicative of the actual payment at maturity. The numbers appearing in the table below have been rounded for ease of analysis.

Hypothetical Examples of Amounts Payable at Maturity

The examples below illustrate the hypothetical Payment at Maturity amount (including, where applicable, the payment of the Additional Amount) per $1,000 principal amount note, based on hypothetical values for the Basket Index Starting Level (which will be determined on the Pricing Date), the Basket Currency Starting Levels (which will be determined on the Pricing Date), the Basket Index Ending Level (which will be determined on the

TS-4

Valuation Date), the Basket Currency Ending Levels (which will be determined on the Valuation Date), the Starting Equity Component Level (which will be set at 450 on the Pricing Date), the Ending Equity Component Level (which will be determined on the Valuation Date), the Starting Currency Component Level (which will be set at 550 on the Pricing Date), the Ending Currency Component Level (which will be determined on the Valuation Date) and a Participation Rate of 115% (the midpoint of the range of 110% to 120%, the actual Participation Rate will be determined on the Pricing Date). The following results are based solely on the hypothetical examples cited; the hypothetical values above have been chosen arbitrarily for the purpose of these examples, are not associated with Lehman Brothers Research forecasts and should not be taken as indicative of the future performance of the Basket Index or the Basket Currencies. Numbers in the examples have been rounded for ease of analysis.

Example 1: The Basket Index Ending Level is greater than the Basket Index Starting Level. As a result, the level of the Ending Equity Component Level increases from a Starting Equity Component Level of 450 to an Ending Equity Component Level of 549.000. The Basket Currency Ending Levels of the BRL, the RUB and the INR are lower than their respective Basket Currency Starting Levels (i.e., the BRL, the RUB and the INR have appreciated relative to the USD). As a result, the Ending Currency Component Level increases from a Starting Currency Component Level of 550 to an Ending Currency Component Level of 678.333.

Because the Ending Basket Level is the sum of the Ending Equity Component Level and the Ending Currency Component Level (549.000 + 678.348 = 1,227.35) and is above the Starting Basket Level of 1,000, the payment at maturity is equal to $1,261.40 per $1,000 principal amount note, and is calculated as follows:

$1,000 + [$1,000 × 0.2274 × 1.15] = $1,261.51

.2274 = Basket Level up 22.74%

1.15 = 115% Participation Rate

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

Basket Index	Hypothetical Basket Index Starting Level (on Pricing Date)	Hypothetical Basket Index Ending Level (on Valuation Date)	Hypothetical Basket Index Return	Weighting	Hypothetical Weighted Return on Basket Index
SBR	2,824.71	3,446.15	22.0%	100.00%	22.000%
Total Return on Equity Component =					22.000%
Ending Equity Component Level = 450 × (1 + Basket Index Return) =					549.000
Basket Currency	Hypothetical Basket Currency Starting Level (on Pricing Date)	Hypothetical Basket Currency Ending Level (on Valuation Date)	Hypothetical Basket Currency Return	Weighting	Hypothetical Weighted Return on Respective Basket Currency
BRL	1.7455	1.4546	20.0%	33.33%	6.667%
RUB	24.4910	22.2645	10.0%	33.33%	3.333%
INR	39.3600	28.1143	40.0%	33.34%	13.336%
		Total Return on Currency Component =			23.336%
Ending Currency Component Level = 550 × (1 + (sum of (Basket Currency Return × Basket Currency Weighting) for all Basket Currencies)) =					678.348

Example 2: The Basket Index Ending Level is greater than the Basket Index Starting Level. As a result, the level of the Ending Equity Component Level increases from a Starting Equity Component Level of 450 to an Ending Equity Component Level of 675.000. The Basket Currency Ending Levels of the BRL and the INR are greater than their respective Basket Currency Starting Levels (i.e., the BRL and the INR have depreciated relative to the USD), but the Basket Currency Ending Level of the RUB is lower than its

TS-5

Basket Currency Starting Level (i.e., the RUB has appreciated relative to the USD). The decrease in the values of the BRL and the INR are not offset by the increase in the value of the RUB. As a result, the Ending Currency Component Level decreases from a Starting Currency Component Level of 550 to an Ending Currency Component Level of 509.667.

Because the Ending Basket Level is the sum of the Ending Equity Component Level and the Ending Currency Component Level (675.000 + 509.662 = 1,184.662) and is above the Starting Basket Level of 1,000, the payment at maturity is equal to $1,212.41 per $1,000 principal amount note, and is calculated as follows:

$1,000 + [$1,000 × 0.1847 × 1.15] = $1,212.41

.1847 = Basket Level up 18.47%

1.15 = 115% Participation Rate

INR	39.3600	44.7273	-12.0%	33.34%	-4.001%
		Total Return on Currency Component =			-7.334%
Ending Currency Component Level = 550 × (1 + (sum of (Basket Currency Return × Basket Currency Weighting) for all Basket Currencies)) =					509.662

Example 3: The Basket Index Ending Level is lower than the Basket Index Starting Level. As a result, the level of the Ending Equity Component Level decreases from a Starting Equity Component Level of 450 to an Ending Equity Component Level of 360.000. The Basket Currency Ending Levels of the BRL and the INR are greater than their respective Basket Currency Starting Levels (i.e., the BRL and the INR have depreciated relative to the USD), but the Basket Currency Ending Level of the RUB is lower than its Basket Currency Starting Level (i.e., the RUB has appreciated relative to the USD). The decrease in the values of the BRL and the INR are more than offset by the increase in the value of the RUB. As a result, the Ending Currency Component Level increases from a Starting Currency Component Level of 550 to an Ending Currency Basket Level of 559.167.

Because the Ending Basket Level is the sum of the Ending Equity Component Level and the Ending Currency Component Level (360.000 + 559.159 = 919.159) and is not greater than the Basket Starting Value of 1,000, the payment at maturity is equal to $1,000 per $1,000 principal amount note.

		Total Return on Currency Component =			1.665%
Ending Currency Component Level = 550 × (1 + (sum of (Basket Currency Return × Basket Currency Weighting) for all Basket Currencies)) =					559.159

Example 4: The Basket Index Ending Level is lower than the Basket Index Starting Level. As a result, the level of the Ending Equity Component Level decreases from a Starting Component Basket Level of 450 to an Ending Equity Component Level of 270.000. The Basket Currency Ending Levels of the BRL, the RUB and the INR are greater than their respective Basket Currency Starting Levels (i.e., the BRL, the RUB and the INR have depreciated relative to the USD). As a result, the Ending Currency Component Level decreases from a Starting Currency Component Level of 550 to an Ending Currency Component Level of 449.185.

Because the Ending Basket Level is the sum of the Ending Equity Component Level and the Ending Currency Component Level (270.000 + 449.158 = 719.158) and is less than the Basket Starting Value of 1,000, the payment at maturity is equal to $1,000 per $1,000 principal amount note.

Supplemental Plan of Distribution

We have agreed to sell to Lehman Brothers Inc., and the Lehman Brothers Inc. has agreed to purchase, all of the notes at the price indicated on the cover of the pricing supplement.

We have agreed to indemnify Lehman Brothers Inc. against liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments that Lehman Brothers Inc. may be required to make relating to these liabilities as described in the MTN prospectus supplement and the base prospectus.

We expect to deliver the Notes against payment on or about February 29, 2008, which is the fifth business day following the Pricing Date. Under Rule 15c6-1 of the Exchange Act, 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, if any purchaser wishes to trade the Notes on the Pricing Date, it will be required, by virtue of the fact that the Notes initially will settle on the fifth business day following the Pricing Date, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement.

Lehman Brothers Inc. will offer the notes initially at a public offering price equal to the issue price set forth on the cover of the pricing supplement. After the initial public offering, the public offering price may from time to time be varied by Lehman Brothers Inc.

We or our affiliate will enter into swap agreements or related hedge transactions with one of our other affiliates or unaffiliated counterparties in connection with the sale of the notes and Lehman Brothers Inc. and/or an affiliate will earn additional income as a result of payments pursuant to the swap, or related hedge transactions.
