Summary Description

The notes are designed for investors who seek early exit prior to maturity at a premium if the closing price of a share of the Index Fund is at or above its Call Price on either of the two semi-annual Review Dates. If the notes are not automatically called, and the price per share of the Index Fund does not close below the Initial Share Price by more than the Protection Percentage on the Final Review Date, you will receive a cash payment equal to your initial investment of $1,000 per note; provided, however, that you may lose some or all of your principal if the price of a share of the Index Fund closes below the Initial Share Price by more than the Protection Percentage on the Final Review Date, as described below. Investors should be willing to forgo interest and dividend payments during the term of the notes and be willing to lose some or all of their principal.

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. 990-I (which supplements the description of the general terms of the notes) and underlying supplement no. 930 (which describes the Index Fund, including risk factors specific to it). Buyers should rely upon the base prospectus, the MTN prospectus supplement, product supplement no. 990-I, underlying supplement no. 930, this term sheet and any other relevant terms supplement for complete details. To the extent that there are any inconsistencies among the documents listed below, this term sheet shall supersede product supplement no. 990-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. 990-I and “Risk Factors” in the accompanying underlying supplement no. 930, 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.

Selected Purchase Considerations

• Appreciation Potential: If the Index Fund closing price on a Review Date is above or equal to the Call Price, the notes will automatically be called and your investment will yield a payment per $1,000 principal amount note of $1,000 plus: (i) (8.50% to 11.25%)^* × $1,000, if called on the First Review Date, or (ii) the greater of (a) (17.00% to 22.50%)^* × $1,000 and (b) the Share Return × $1,000, if called on the Final Review Date. Because the notes are our senior unsecured obligations, payment of any amount if automatically called or at maturity is subject to our ability to pay our obligations as they become due.

*The actual percentage applicable to the First Review Date and the Final Review Date will be determined on the Pricing Date but will not be less than 8.50% and 17.00%, respectively.

• Potential Early Exit with Appreciation as a Result of Automatic Call Feature: While the original term of the notes is approximately one year, if the Index Fund closing price is at or above the Call Price on a Review Date, the notes will be automatically called before maturity and you will be entitled to the applicable payment set forth on the cover of this term sheet.

• Limited Protection Against Loss: If the notes are not automatically called and a Trigger Event has not occurred, you will be entitled to receive the full principal amount of your notes at maturity. If the Share Price is more than 20% below the Initial Share Price on the Final Review Date, then, for every 1% that the Final Share Price is below the Initial Share Price, you will lose an amount equal to 1% of the principal amount of your notes. YOU MAY LOSE SOME OR ALL OF YOUR INVESTMENT IF THE NOTES ARE NOT AUTOMATICALLY CALLED AND A TRIGGER EVENT HAS OCCURRED.

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 a cash-settled financial contract, rather than as a debt instrument.

Potential Application of the Constructive Ownership Rules. A “constructive ownership transaction” includes a contract under which an investor will receive payment equal to or credit for the future value of any equity interest in a regulated investment company (such as the Underlying Shares). Under the “constructive ownership” rules, if an investment in the notes is treated as a “constructive ownership transaction,” any long-term capital gain recognized by a United States holder in respect of a note will be recharacterized as ordinary income to the extent such gain exceeds the amount of “net underlying long-term capital gain” (as defined in Section 1260 of the Internal Revenue Code of 1986, as amended (the “Code”)) of the United States holder, determined as if the United States holder had acquired the Underlying Shares on the original issue date of the notes at fair market value and sold them at fair market value on the Maturity Date (if the notes were held until the Maturity Date) or on the date of sale (including pursuant to an automatic call) or exchange of the notes (if the notes were sold (including pursuant to an automatic call) or exchanged prior to the Maturity Date) (the “Excess Gain”). In addition, an interest charge will also apply to any deemed underpayment of tax in respect of any Excess Gain to the extent such gain would have resulted in gross income inclusion for the United States holder in taxable years prior to the taxable year of the sale (including pursuant to an automatic call), exchange or settlement of the notes (assuming such income accrued at a constant rate equal to the applicable federal rate as of the date of sale (including pursuant to an automatic call), exchange or settlement of the notes).

Although the matter is not clear, there exists a substantial risk that an investment in the notes will be treated as a “constructive ownership transaction.” If such treatment applies, it is not entirely clear to what extent any long-term capital gain recognized by a United States holder in respect of the notes will be recharacterized as ordinary income. It is possible, for example, that the amount of the Excess Gain (if any) that would be recharacterized as ordinary income in respect of each note will equal the excess of (i) any long-term capital gain recognized by the United States holder in respect of the note over (ii) the “net underlying long-term capital gain” such United States holder would have had if such United States holder had acquired a number of the Underlying Shares at fair market value on the original issue date of the notes for an amount equal to the “issue price” of the notes and, upon the date of sale (including pursuant to an automatic call), exchange or settlement of the notes, sold such Underlying Shares at fair market value (which would reflect the percentage increase in the value of the Underlying Shares over the term of the notes). Accordingly, United States holders should consult their tax advisors regarding the potential application of the “constructive ownership” rules.

Recent Tax Law Developments. On December 7, 2007, the Internal Revenue Service released a Notice indicating that the Internal Revenue Service and the Treasury Department are considering and seeking comments as to whether holders of instruments similar to the notes should be required to accrue income on a current basis over the term of the notes, regardless of whether any payments are made prior to maturity. In addition, the Notice provides that the Internal Revenue Service and the Treasury Department are considering related issues, including, among other things, whether gain or loss from such instruments should be treated as ordinary or capital, whether foreign holders of such instruments should be subject to withholding tax, whether the tax treatment of such instruments should vary depending upon the nature of the underlying asset, and whether such instruments should be subject to the special “constructive ownership rules” contained in Section 1260 of the Code (as discussed above). It is not possible to predict what changes, if any, will be adopted, or when they will take effect. Any such changes could affect the amount, timing and character of income, gain or loss in respect of the notes, possibly with retroactive effect. Holders are urged to consult their tax advisors concerning the impact of the Notice on their investment in the notes. Subject to future developments with respect to the foregoing, Lehman Brothers Holdings Inc. intends to continue to treat the notes for U.S. federal income tax purposes in accordance with the treatment described in the accompanying product supplement no. 990-I under the headings “Risk Factors” and “Certain U.S. Federal Income Tax Consequences.”

See “Certain U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 990-I.

Selected Risk Factors

An investment in the notes involves significant risks. Investing in the notes is not equivalent to investing directly in the Index Fund, any of the stocks held by the Index Fund or any of the stocks included in the Underlying Index. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement no. 990-I and in the “Risk Factors” section of the accompanying underlying supplement no. 930. 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.

• Your Investment in the Notes May Result in a Significant Loss: The notes do not pay interest and do not guarantee any return of principal. If the notes are not automatically called, the Payment at Maturity will be based on the Final Share Price and whether the closing price of the Index Fund was below the Trigger Price on the Final Review Date. If the notes are not automatically called and the closing price of the Index Fund is below the Initial Share Price by more than the Protection Percentage of 20% on the Final Review Date, you will receive at maturity an amount that will be less than the principal amount of each note and may be zero. In addition, on the Pricing Date, share prices generally in the market and share prices for the Index Fund in particular may be significantly higher than historical averages, which could increase the likelihood of subsequent declines in the price of a share of the Index Fund and of a Trigger Event and could reduce the likelihood that the notes will be automatically called. You may lose the entire principal amount of your notes.

• Limited Return on the Notes if the Notes Are Called on First Review Date: If your notes are automatically called on the First Review Date, your potential gain on the notes will be limited to the call premium applicable for the First Review Date, as set forth on the cover of this term sheet, regardless of the Index Fund appreciation on the First Review Date, which may be significant. Similarly, because the determination of whether the notes will be called (and, if the notes are not called, the Final Share Price) will be based on the Index Fund closing price on a limited number of Review Dates prior to the Maturity Date, your return may be adversely affected by a sudden or temporary decrease in the Index Fund closing price on either or both of the Review Dates. Conversely, you will not benefit from higher Index Fund closing prices at any time during the term of the notes other than on the Review Dates. As a result, you may receive a lower return on the notes than you would receive if you were to take a position in the Index Fund, any of the stocks held by the Index Fund or any of the stocks included in the Underlying Index.

• The Notes Will Not Pay More Than the Principal Amount at Maturity Plus Any Applicable Call Premiums, and Principal Protection is Under Limited Circumstances: Your return of principal at maturity is protected so long as the Share Price does not fall below the Trigger Price. However, if the Share Price falls below the Trigger Price, you could lose the entire principal amount of your notes.

• 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 the stocks held by the Index Fund or stocks included in the Underlying Index would have.

• Differences Between the Index Fund and the Underlying Index: The Index Fund does not fully replicate the Underlying Index, may hold securities not included in the Underlying Index and will reflect transaction costs and fees that are not included in the calculation of the Underlying Index, all of which may lead to a lack of correlation between the Index Fund and the Underlying Index. In addition, because the shares of the Index Fund are traded on the American Stock Exchange and are subject to market supply and investor demand, the market price per share of the Index Fund may differ from the net asset value per share of the Index Fund.

• Dealer Incentives: We and our affiliates act in various capacities with respect to the notes. Lehman Brothers Inc. and others of our affiliates may act as principals, agents or dealers 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 up to $15.00 per note to the principals, agents and dealers in connection with the distribution of the notes.

• Certain Built-In Costs Are Likely to Adversely Affect the Value of the Notes Prior to Maturity: While the payment described in this term sheet after an automatic call or at maturity 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, is likely to 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 THE NOTES TO MATURITY.

• 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

TS-3

Recommendations Could Affect the Price Per Share of the Index Fund or the Value of the Notes: We, our affiliates and our agents publish research from time to time on financial markets and other matters that may influence the value of the notes, and we, our affiliates and our agents express opinions or provide recommendations that are inconsistent with purchasing or holding the notes. We, our affiliates and our 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 our 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.

• We Cannot Control Actions by the Companies Whose Stocks or Other Equity Securities are Represented in the Financial Select Sector Index: We are one of the companies that are represented in the Underlying Index, but we are not affiliated with any of the other companies whose stock is represented in the Underlying Index. As a result, we will have no ability to control the actions of such companies, including actions that could affect the value of the stocks underlying the Underlying Index or your notes. None of the money you pay us will go to any of the companies represented in the Underlying Index, and none of those companies will be involved in the offering of the notes in any way. Neither those companies nor we will have any obligation to consider your interests as a holder of the notes in taking any corporate actions that might affect the value of your 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.

• 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. The economic interests of the calculation agent and other affiliates of ours in their performance of these duties are potentially adverse to your interests as an investor in the notes.

• 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.

• The Final Share Price May be Below the Share Price on the Maturity Date or at Other Times during the Term of the Notes: Because the Final Share Price is calculated based on the Share Price on the Final Review Date and not on the Maturity Date or any other date during the term of the notes, significant volatility in the Share Price at or around the time of the Final Review Date could materially affect the Payment at Maturity. For example, a significant decline in the Share Price on the Final Review Date would result in a corresponding decline in the Payment at Maturity notwithstanding a significant increase in the Share Price on any date or dates subsequent to the Final Review Date. Under these circumstances, you may receive a lower Payment at Maturity than you would have received if you had invested directly in the Index Fund, the stocks held by the Index Fund or the stocks included in the Underlying Index, the value of which could be realized on any date or dates other than, or in addition to, the Final Review Date.

• If the Share Return is Negative and the Absolute Value of the Share Return is Not Significantly Different from the Protection Percentage, the Return on Your Notes Will Be Extremely Sensitive to Small Differences in the Final Share Price. If your notes are not automatically called, a negative Share Return whose absolute value exceeds the Protection Percentage of 20% will result in a loss equal to the full product of the absolute value of the Share Return and your initial investment, not just in a loss proportional to the amount by which the percentage decline in the Share Price exceeds the Protection Percentage. If your notes are not automatically called, a Final Share Price that reflects, for example, a Share Return of -20.0% would result in your receiving, at maturity, the full amount of your initial investment, whereas an incrementally lower Final Share Price, reflecting a Share Return of -20.1%, would result in a loss, at maturity, of 20.1% of your initial investment. In this example, a change of -0.1% in the Share Return would lead to a loss of over 20%. Consequently, you should note that for a Share Return in the vicinity of -20%, a small negative change in the Final Share Price could have a profound adverse effect on the return on your notes if your notes are not automatically called.

• Many Economic and Market Factors Will Impact the Value of the Notes: In addition to the price per share of the Index Fund 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. 990-I and the accompanying underlying supplement no. 930.

• 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.

• Anti-Dilution Protection is Limited: The calculation agent will make adjustments to the Share Adjustment Factor for certain adjustment events affecting the Index Fund. However, the calculation agent will not make an adjustment in response to all events that could affect the Index Fund. If an event occurs that does not require the calculation agent to make an adjustment, the value of the notes may be materially and adversely affected.

Hypothetical Examples of Amounts Payable Upon An Automatic Call or At Maturity

The following table illustrates the hypothetical simple (i.e., not compounded) total return that could be realized on the notes on the applicable Review Date or at maturity based on a range of hypothetical Share Prices on the Review Dates. The following table assumes a Call Price equal to a hypothetical Initial Share Price of $29.14. The table assumes that the percentages used to calculate the Payment if Called on applicable Review Dates are 9.875% and 19.75% for the First Review Date and the Final Review Date, respectively (based on the midpoint of the ranges of 8.50% to 11.25% and 17.00% to 22.50% expected call premium, or on the First Review Date and the Final Review Date, respectively; the actual percentages will be determined on the Pricing Date). There will be only one payment on the notes, whether they are automatically called or remain outstanding (and uncalled) at the Maturity Date. The following results are based solely on the hypothetical examples cited. The numbers appearing in the table below have been rounded for ease of analysis.

The following examples illustrate how the total returns set forth in the highlighted rows in the table above are calculated.

Example 1 (fifth highlighted row): The price per share of the Index Fund increases from the Initial Share Price of $29.14 to a closing price of $34.97 on the First Review Date. Because the Index Fund closing price on the First Review Date of $34.97 is above the Call Price of $29.14, the notes are automatically called, and the investor receives a single payment of $1,098.75 per $1,000 principal amount note calculated as follows:

$1,000 + ($1,000 × 9.875%) = $1,098.75

Example 2 (third highlighted row): The price per share of the Index Fund decreases from the Initial Share Price of $29.14 to a closing price of $17.48 on the First Review Date and increases from the Initial Share Price of $29.14 to a closing price of $32.05 on the Final Review Date. Because (a) the Index Fund closing price on the Final Review Date of $32.05 is above the Call Price of $29.14 and (b) the Index Fund closing price on the Final Review Date is not more than 19.75% above the Initial Share Price, the notes are automatically called on the Final Review Date and the investor receives a single payment of $1,197.50 per $1,000 principal amount note calculated as follows:

$1,000 + ($1,000 × 19.75%) = $1,197.50

Example 3 (fourth highlighted row): The price per share of the Index Fund decreases from the Initial Share Price of $29.14 to a closing price of $26.23 on the First Review Date and increases from the Initial Share Price of $29.14 to a closing price of $37.88 on the Final Review Date. Because (a) the Index Fund closing price on the Final Review Date of $32.05 is above the Call Price of $29.14 and (b) the Index Fund closing price on the Final Review Date is more than 19.75% above the Initial Share Price, the notes are automatically called on the Final Review Date and the investor receives a single payment of $1,300.00 per $1,000 principal amount note calculated as follows:

$1,000 + ($1,000 × 30%) = $1,300.00

Example 4 (second highlighted row): The price per share of the Index Fund decreases from the Initial Share Price of $29.14 to a closing price of $24.77 on the First Review Date and $23.31 on the Final Review Date. Because (a) the Index Fund closing price on each of the Review Dates ($24.77 and $23.31) is below the Call Price of $29.14, and (b) the Final Share Price is not more than 20% below the Initial Share Price, the notes are not automatically called and the Payment at Maturity is the principal amount of $1,000 per $1,000 principal amount note.

Example 5 (first highlighted row): The price per share of the Index Fund decreases from the Initial Share Price of $29.14 to a closing price of $20.40 on the First Review Date and $21.86 on the Final Review Date. Because (a) the Index Fund closing price on each of the Review Dates ($20.40 and $21.86) is below the Call Price of $29.14, and (b) the Final Share Price is more than 20% below the Initial Share Price, the notes are not automatically called and the investor will receive a payment that is less than the principal amount of each $1,000 principal amount note, calculated as follows:

$1,000 + ($1,000 × -25%) = $750.00
