  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. 60-I (which supplements the description of the general terms of the Notes) and underlying supplement no. 800 (which describes each of the Basket Indices, as defined herein, including risk factors specific to each). Buyers should rely upon the base prospectus, MTN prospectus supplement, product supplement no. 60-I, underlying supplement no. 800, 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. 60-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. 60-I and “Risk Factors” in the accompanying underlying supplement no. 800, as the Notes involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisers 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.

References to “Lehman Brothers,” “we,” “our” and “us” refer only to Lehman Brothers Holdings Inc. and not to its consolidated subsidiaries. In this document, “Notes” refers to the 100% Principal Protection Enhanced Participation Notes Linked to a Basket of Asian Indices that are offered hereby, unless the context otherwise requires.

  Selected Purchase Considerations

¨ Uncapped Appreciation Potential: 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 Basket, which consists of the Nikkei 225^SM Index, the MSCI Singapore Free Index^SM and the MSCI Taiwan^SM Index. The Nikkei 225^SM Index consists of 225 stocks listed on the First Section of the Tokyo Stock Exchange, representing a broad cross-section of Japanese industries. The MSCI Singapore Free Index^SM targets an 85% free float adjusted market representation level within each industry group in Singapore. The MSCI Taiwan^SM Index targets an 85% free float adjusted market representation level within each industry group in Taiwan. For additional information about each Basket Component, see the information set forth under “The Nikkei 225^SM Index,” “The MSCI Singapore Free Index^SM” and “The MSCI Taiwan^SM Index” in the accompanying underlying supplement no. 800.

¨ 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 interest payments on the Notes), and the adjustments thereto, in respect of the Notes. See “Certain U.S. Federal Income Tax Consequences” in product supplement no. 60-I.

  Selected Risk Factors

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. 60-I and in the “Risk Factors” section of the accompanying underlying supplement no. 800. 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.

¨ No Principal Protection Unless You Hold the Notes To Maturity: The Notes are not designed to be short-term trading instruments. You will receive at least the minimum payment of 100% of the principal amount of your Notes if you hold your Notes to maturity. If you sell your Notes in the secondary market prior to maturity, you will not receive principal protection. YOU SHOULD BE WILLING TO HOLD YOUR NOTES TO MATURITY.

¨ Market Risk: The return on the Notes at maturity is linked to the positive performance of the Basket, and will depend on whether, and the extent to which, the Basket Return is positive. YOU WILL RECEIVE NO MORE THAN THE FULL PRINCIPAL AMOUNT OF YOUR NOTES AT MATURITY IF THE BASKET RETURN IS ZERO OR NEGATIVE.

¨ The Notes Might Not Pay More Than the Principal Amount: You may receive a lower payment at maturity than you would have received if you had invested in the Basket Indices, any of the stocks included in the Basket Indices, or contracts related to the Basket Indices. If the Basket Ending Level is not above the Basket Starting Level, the Additional Amount will be zero. This will be true even if the level of the Basket was above the Basket Starting Level at some time during the term of the Notes but falls below the Basket Starting Level on the Final Valuation Date.

¨ Changes in the Level of the Basket Indices May Offset Each Other: The Notes are linked to a substantially equally weighted basket composed of Basket Indices. At a time when the level of one or more Basket Indices increases, the level of the other Basket Index or 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 the other Basket Index or 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 Related to the U.S. Dollar that Might Affect the Nikkei 225^SM Index, the MSCI Singapore Free Index^SM and the MSCI Taiwan^SM Index: 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 Nikkei 225^SM Index, the MSCI Singapore Free Index^SM and the MSCI Taiwan^SM Index 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.

¨ Dealer Incentives: We, our affiliates and agents 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. We will pay compensation of up to $5 per 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.

4

¨ 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 to which the Notes are Linked or 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 are inconsistent with purchasing or holding the Notes. We, our affiliates and agents may have published research or other opinions that are inconsistent with the investment view implicit in the Notes. 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. Investors should make their own independent investigation of the merits of investing in the Notes which are linked to the Basket.

¨ 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 accompanying product supplement no. 60-I.

  Scenario Analysis and Examples at Maturity

The following scenario analysis and examples assume a Participation Rate of 110%, the minimum Participation Rate, and a range of Basket Returns from +40% to -40%. The actual Participation Rate 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 120. Because the Basket Ending Level is 120 and the Basket Starting Level is 100, the Basket Return is 20% calculated as follows:

(120 – 100)/100 = 20%

Because the Basket Return is 20%, the Additional Amount is equal to $220 and the payment at maturity is equal to $1,220 per $1,000 principal amount Note calculated as follows:

$1,000 + ($1,000 × 20% × 110%) = $1,220

Example 2—The level of the Basket decreases from the Basket Starting Level of 100 to a Basket Ending Level of 80. Because the Basket Ending Level is 80 and the Basket Starting Level is 100, the Basket Return is -20% calculated as follows:

(80 – 100)/100 = -20%

Because the Basket Return is -20%, the Additional Amount is equal to $0 and 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 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.

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 may earn additional income as a result of payments pursuant to the swap or related hedge transactions.
