Return Optimization Securities Linked to an International Index Basket
Offering Potential Enhanced Returns in a Moderate-Return Environment Lehman Brothers Holdings Inc. Notes Linked to an International Index Basket due March 31, 2009

Investment Description

These Return Optimization Securities Linked to an International Index Basket (the “Notes”) provide potential enhanced returns based on the positive performance of a basket composed of six international equity indices: the Dow Jones EURO STOXX 50^® Index, the FTSE 100 Index^®, the Nikkei 225^SM Index, the Swiss Market Index^®, the S&P^®/ASX 200 Index and the MSCI Emerging Markets Index^SM. The Notes are designed to enhance returns in a moderate-return environment - meaning an environment in which stocks generally experience no more than moderate appreciation. If the Basket Return is positive, at the maturity of the Notes you will receive your principal plus a return equaling 300% of the Basket Return, up to the Maximum Gain, providing you with an opportunity to outperform the Basket. If the Basket Return is negative, at maturity of the Notes you will receive your principal reduced by a percentage equal to the absolute value of the Basket Return. Investing in the Notes is subject to significant risks, including potential loss of principal and a capped appreciation at maturity.

Additional Information about Lehman Brothers Holdings Inc. and 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. 730-I (which supplements the description of the general terms of the Notes) and underlying supplement no. 890 (which describes each of the Basket Indices, as defined herein, including risk factors specific to each). Buyers should rely upon the base prospectus, the MTN prospectus supplement, product supplement no. 730-I, underlying supplement no. 890, this term sheet and any other relevant terms supplement and any relevant free writing prospectus for complete details. This term sheet, together with the documents listed below, contains the terms of the Notes and supersedes all prior or contemporaneous oral statements as well as any other written materials including preliminary pricing terms, correspondence, trade ideas, structures for implementation, sample structures, fact sheets, brochures or other educational materials of ours. To the extent that there are any inconsistencies among the documents listed below, this term sheet shall supersede product supplement no. 730-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. 730-I and “Risk Factors” in the accompanying underlying supplement no. 890, 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 UBS Financial Services Inc. toll-free at 1-877-827-2010 or Lehman Brothers Inc. toll-free at 1-888-603-5847.

Investor Suitability

The Notes may be suitable for you if, among other considerations:

^¨ You believe that the Basket will appreciate moderately—meaning that you believe the Basket will appreciate over the term of the Notes and that such appreciation, as leveraged by the Leverage Factor, is unlikely to exceed the indicative Maximum Gain at maturity

^¨ You are willing to risk losing some or all of your investment

^¨ You are willing to hold the Notes to maturity

^¨ You do not seek current income from this investment

^¨ You are willing to invest in the Notes based on the range indicated for the Maximum Gain (the actual Maximum Gain will be determined on the Trade Date)

The Notes may not be suitable for you if, among other considerations:

^¨ You do not seek an investment with exposure to international developed markets or emerging markets

^¨ You are unable or unwilling to hold the Notes to maturity

^¨ You seek an investment whose return is not subject to a cap that is equivalent to the Maximum Gain, which will be between 28% and 30% (the actual Maximum Gain will be determined on the Trade Date)

^¨ You prefer the lower risk, and therefore accept the potentially lower returns, of fixed income investments with comparable maturities and credit ratings

^¨ You seek current income from your investments

^¨ You seek an investment for which there will be an active secondary market

^¨ You seek an investment that offers principal protection when the Notes are held to maturity

The suitability considerations identified above are not exhaustive. Whether or not the Notes are a suitable investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting, and other advisors have carefully considered the suitability of an investment in the Notes in light of your particular circumstances. You should also review carefully the “Key Risks” on page 5, “Risk Factors” in product supplement no. 730-I, underlying supplement no. 890 and the MTN prospectus supplement for risks related to an investment in the Notes.

Determining Payment at Maturity

¹ Lehman Brothers Holdings Inc. is rated A+ by Standard & Poor’s, A1 by Moody’s and AA- by Fitch. A credit rating reflects the creditworthiness of Lehman Brothers Holdings Inc. and is not a recommendation to buy, sell or hold securities, and it may be subject to revision or withdrawal at any time by the assigning rating organization. Each rating should be evaluated independently of any other rating. The creditworthiness of the issuer does not affect or enhance the likely performance of the investment other than the ability of the issuer to meet its obligations.

Scenario Analysis and Examples at Maturity

The following scenario analysis and examples reflect the Leverage Factor of 3 and assume a Maximum Gain of 29% (the midpoint of the range of 28% to 30%) and a range of Basket Returns from +40% to -40%. The actual Maximum Gain will be set on the Trade Date.

Example 1—The level of the Basket increases from the Basket Starting Level of 100 to a Basket Ending Level of 105. Because the Basket Ending Level is 105 and the Basket Starting Level is 100, the Basket Return is 5%, calculated as follows:

(105 – 100)/100 = 5%

Because the Basket Return is 5%, the payment at maturity is equal to $11.50 per $10.00 principal amount Note calculated as follows:

$10 + ($10 × 5% × 3) = $11.50

Example 2—The level of the Basket increases from the Basket Starting Level of 100 to a Basket Ending Level of 115. Because the Basket Ending Level is 115 and the Basket Starting Level is 100, the Basket Return is 15% calculated as follows:

(115 – 100)/100 = 15%

Because the Basket Return is 15% and the Leverage Factor is 3, the return on the Note would be equal to 45%, but it is subject to the Maximum Gain of 29%. Therefore, the payment at maturity is equal to $12.90 per $10.00 principal amount Note calculated as follows:

$10 + ($10 × 29%) = $12.90

Example 3—The level of the Basket decreases from the Basket Starting Level of 100 to a Basket Ending Level of 90. Because the Basket Ending Level is 90 and the Basket Starting Level is 100, the Basket Return is -10%, calculated as follows:

(90 – 100)/100 = -10%

Because the Basket Return is -10%, the payment at maturity is equal to $9.00 per $10.00 principal amount Note calculated as follows:

$10 + ($10 × -10%) = $9.00

What are the tax consequences of the Notes?

Lehman Brothers Holdings Inc. intends to treat, and by purchasing a Note, for all tax purposes, you agree to treat, a Note as a cash-settled financial contract, rather than as a debt instrument.

Upon the receipt of cash on the Maturity Date of the Notes, you will recognize gain or loss. The amount of that gain or loss will be the extent to which the amount of the cash received differs from your tax basis in the Note. Your tax basis in a Note generally will equal the amount you paid to acquire the Note. It is uncertain whether any such gain or loss would be treated as ordinary income or loss or capital gain or loss. Absent a future clarification in current law (by an administrative determination, judicial ruling or otherwise), where required, Lehman Brothers Holdings Inc. intends to report any such gain or loss to the Internal Revenue Service in a manner consistent with the treatment of that gain or loss as capital gain or loss. If that gain or loss is treated as capital gain or loss, then any gain or loss will generally be long-term capital gain or loss if you have held the Note for more than one year as of the Maturity Date. If you are an individual, long-term capital gains will be subject to reduced rates of taxation. The deductibility of capital losses is subject to certain limitations.

Upon a sale, exchange or other disposition of a Note prior to the Maturity Date, you will recognize gain or loss in an amount equal to the difference between the amount of cash received and your tax basis in the Note. Any such gain or loss will be treated as capital gain or loss. If you have held the Note for more than one year as of the date of such sale, exchange or other disposition, any such capital gain or loss will generally be long-term capital gain or loss. If you are an individual, long-term capital gains will be subject to reduced rates of taxation. The deductibility of capital losses is subject to limitations.

See “Certain U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 730-I.

Key Risks

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in the Basket Indices or any of the stocks included in the Basket Indices. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement no. 730-I and in the “Risk Factors” section of the accompanying underlying supplement no. 890. 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.

^¨ Potentially Full Market Risk; You May Lose Some or All of Your Principal: The return on the Notes at maturity is linked to the performance of the Basket, and will depend on whether, and the extent to which, the Basket Return is positive. If the Basket Ending Level is less than the Basket Starting Level, you will lose 1% of your principal for every 1% of the amount by which the Basket Ending Level is less than the Basket Starting Level. YOU MAY LOSE THE ENTIRE PRINCIPAL AMOUNT OF YOUR INVESTMENT.

^¨ Maximum Gain: An investment in the Basket may exceed the Maximum Gain of between 28% and 30% (to be determined on the Trade Date). YOU WILL NOT RECEIVE A RETURN ON THE NOTES GREATER THAN THE MAXIMUM GAIN.

^¨ Changes in the Level of the Basket Indices May Offset Each Other: The Notes are linked to a weighted basket composed of the Basket Indices. At a time when the level of one or more of the other Basket Indices increases, the level of one or more of the other Basket Indices may not increase as much or may even decline. Therefore, in calculating the Basket Ending Level, increases in the level of one or more of the Basket Indices may be moderated, or offset, by lesser increases or declines in the level of one or more of the other Basket Indices.

^¨ 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 Indices would have.

^¨ Certain Built-in Costs are Likely to Adversely Affect the Value of the Notes Prior to Maturity: While the payment at maturity described in this term sheet is based on the full principal amount of your Notes, 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 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.

^¨ The Basket Return Will Not Be Adjusted for Changes in Exchange Rates Relative to the U.S. Dollar, But the Notes Will Have Some Exposure to Exchange Rate Fluctuations: The value of your Notes will not be adjusted for exchange rate fluctuations between the U.S. dollar and the currencies in which the stocks included in the Basket Indices are based. Therefore, if the applicable currencies appreciate or depreciate relative to the U.S. dollar over the term of the Notes, you will not receive any additional payment or incur any reduction in your return, if any, at maturity. However, because one of the Basket Indices (the MSCI Emerging Markets Index^SM)—but not its component stocks—is denominated in U.S. dollars, you will have foreign currency exposure with respect to that Basket Index, and the value of your Notes will be affected by exchange rate fluctuations between the U.S. dollar and the currencies in which such component stocks are based. If the applicable currencies appreciate or depreciate relative to the U.S. dollar over the term of the Notes, the value of your Notes may increase or decrease at maturity.

^¨ Dealer Incentives: We, our affiliates and agents, and UBS Financial Services Inc., and its 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 the Notes instead of other investments. We will pay compensation of $0.175 per $10 principal amount Note to the principals, agents and dealers in connection with the distribution of the Notes.

^¨ 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. If you are an employee of Lehman Brothers Holdings Inc. or one of our affiliates, you may not be able to purchase the Notes from us and your ability to sell or trade the Notes in the secondary market may be limited.

^¨ 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.

^¨ We and our Affiliates and Agents May Publish Research, Express Opinions or Provide Recommendations that are Inconsistent with Investing in or Holding the Notes. Any Such Research, Opinions or Recommendations Could Affect the Level of the Basket and, Consequently, the Value of the Notes: We, our affiliates and agents publish research from time to time on financial markets and other matters that may influence the value of the Notes, or express opinions or provide recommendations that may be inconsistent with purchasing or holding the Notes. We, our affiliates and agents may publish or may have published research or other opinions that are inconsistent with an investment position in the Dow Jones EURO STOXX 50^® Index, the FTSE 100 Index^®, the Nikkei 225^SM Index, the Swiss Market Index^®, the S&P^®/ASX 200 Index and the MSCI Emerging Markets Index^SM. Any research, opinions or recommendations expressed by us, our affiliates or agents may not be consistent with each other and may be modified from time to time without notice. Additionally, UBS Financial Services Inc. and its affiliates may publish or may have published research or other opinions that are inconsistent with an investment position in the Dow Jones EURO STOXX 50^® Index, the FTSE 100 Index^®, the Nikkei 225^SM Index, the Swiss Market Index^®, the S&P^®/ASX 200 Index and the MSCI Emerging Markets Index^SM. Investors should make their own independent investigation of the merits of investing in the Notes.

^¨ 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. 730-I.

^¨ There are Risks in Emerging Markets: Countries with emerging markets may have relatively unstable governments, may present risks of nationalization of businesses, may impose restrictions on foreign ownership, foreign currency exchange and the repatriation of assets, and may be less protective of property rights than more developed countries. The economies of countries with emerging markets may be based on only a few industries, may be highly vulnerable to changes in local, regional and global economic and trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.

^¨ Uncertain Tax Treatment: Significant aspects of the tax treatment of the Notes are uncertain. You should consult your own tax advisor about your own tax situation before investing in the Notes.
