Investment Description

This term sheet relates to two separate issuances of 100% Principal Protection Absolute Return Barrier Notes Linked to the S&P 500^® Index (each, a “Note” and collectively, the “Notes”). The Notes provide an opportunity to potentially hedge your exposure to equity securities as represented by the S&P 500^® Index (the “Index”), while benefiting from moderately positive or negative returns of the Index. If the Index never closes above the applicable Upper Index Barrier or below the applicable Lower Index Barrier on any trading day during the Observation Period, at maturity you will receive your principal plus a return equal to the absolute value of the applicable Index Return. Otherwise, at maturity you will receive only your principal.

Features

q Hedging Opportunity—You have the potential to hedge your exposure to the S&P 500^® Index while benefiting from moderately positive or negative returns over the 1 year term of the Notes.

q Potential for Equity-Linked Performance—If the Index never closes above the applicable Upper Index Barrier or below the applicable Lower Index Barrier on any trading day during the Observation Period, you will receive an equity-based return that may exceed the return you could receive on traditional fixed income investments.

q Preservation of Capital—At maturity, you will receive a cash payment equal to at least 100% of your principal.

Investor Suitability

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

^¨ You seek an investment that offers 100% principal protection when the Notes are held to maturity

^¨ You believe that the Index will appreciate or depreciate over the Observation Period and that any appreciation or depreciation is unlikely to exceed the applicable Upper Index Barrier or the applicable Lower Index Barrier on any trading day during the Observation Period

^¨ You are willing to hold the Notes to maturity

^¨ You do not seek current income from this investment

^¨ You are willing to invest in securities for which there may be little or no secondary market

^¨ You are willing to forgo dividends paid on the stocks included in the Index

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

^¨ You believe the Index is likely to appreciate or depreciate over the Observation Period and that any appreciation or depreciation is likely to exceed the applicable Upper Index Barrier or the applicable Lower Index Barrier on any trading day during the Observation Period

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

^¨ 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

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. 1140-I, underlying supplement no. 100 and the MTN prospectus supplement for risks related to an investment in the Notes.

  * Calculation assumes that the Index never closes above the Upper Index Barrier or below the Lower Index Barrier on any single trading day during the Observation Period

** Calculation assumes that the Index closes above the Upper Index Barrier or below the Lower Index Barrier on at least one trading day during the Observation Period

Example 1: On a trading day during the Observation Period, the Index closes at 1,710.42, which is 20% above the Index Starting Level, and the Index Ending Level is 10% above the Index Starting Level. Since the Index closed at a level above the Upper Index Barrier, you will receive a Payment at Maturity of $10.00 per $10 Note principal amount (a zero return).

Example 2: During the Observation Period, the Index never closes above the Upper Index Barrier or below the Lower Index Barrier and the Index Ending Level is 1,567.89. The Absolute Index Return is 10%, calculated as follows:

The Absolute Value of: (1,567.89 – 1,425.35)/ 1,425.35 = 10%

You will receive a Payment at Maturity of $11.00 per $10 Note principal amount calculated as follows:

$10 + ($10 × 10%) = $11.00

Example 3: On a trading day during the Observation Period, the Index closes at 1,140.28, which is 20% below the Index Starting Level, and the Index Ending Level is 10% below the Index Starting Level. Since the Index closed at a level below the Lower Index Barrier, you will receive a Payment at Maturity of $10.00 per $10 Note principal amount (a zero return).

Example 4: During the Observation Period, the Index never closes above the Upper Index Barrier or below the Lower Index Barrier and the Index Ending Level is 10% below the Index Starting Level 1,282.82. The Absolute Index Return is 10%, calculated as follows:

The Absolute Value of: (1,282.82 – 1,425.35)/ 1,425.35 = -10%

You will receive a Payment at Maturity of $11.00 per $10 Note principal amount calculated as follows:

$10 + ($10 × 10%) = $11.00

  * Calculation assumes that the Index never closes above the Upper Index Barrier or below the Lower Index Barrier on any single trading day during the Observation Period

** Calculation assumes that the Index closes above the Upper Index Barrier or below the Lower Index Barrier on at least one trading day during the Observation Period

Example 1: On a trading day during the Observation Period, the Index closes at 1,710.42 which is 20% above the Index Starting Level, and the Index Ending Level is 10% above the Index Starting Level. Since the Index closed at a level above the Upper Index Barrier, you will receive a Payment at Maturity of $10.00 per $10 Note principal amount (a zero return).

Example 2: During the Observation Period, the Index never closes above the Upper Index Barrier or below the Lower Index Barrier and the Index Ending Level is 1,567.89. The Absolute Index Return is 10.00%, calculated as follows:

The Absolute Value of: (1,567.89 – 1,425.35)/ 1,425.35 = 10%

You will receive a Payment at Maturity of $11.00 per $10 Note principal amount calculated as follows:

$10 + ($10 × 10%) = $11.00

Example 3: On a trading day during the Observation Period, the Index closes at 1,140.28, which is 20% below the Index Starting Level, and the Index Ending Level is 10% below the Index Starting Level. Since the Index closed at a level below the Lower Index Barrier, you will receive a Payment at Maturity of $10.00 per $10 Note principal amount (a zero return).

Example 4: During the Observation Period, the Index never closes above the Upper Index Barrier or below the Lower Index Barrier and the Index Ending Level is 1,354.08. The Absolute Index Return is 5% calculated as follows:

The Absolute Value of: (1,354.08 – 1,425.35)/ 1,425.35 = -5%

You will receive a Payment at Maturity of $10.50 per $10 Note principal amount calculated as follows:

$10 + ($10 × 5%) = $10.50

Key Risks

An investment in the Notes involves significant risks not associated with an investment in conventional floating rate or fixed rate medium-term notes. Some of these risks are summarized below and are explained in more detail in the “Risk Factors” section of the accompanying product supplement no. 1140-I and in the “Risk Factors” section of the accompanying underlying supplement no. 100, which you are urged to read. 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. Investing in the Notes is not equivalent to investing directly in any of the stocks included in the Index.

^¨ 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: Amounts payable on the Notes and their market value will depend on the performance of the Index and will depend on where the Index closes on any single trading day during the Observation Period. YOU WILL RECEIVE NO MORE THAN THE FULL PRINCIPAL AMOUNT OF YOUR NOTES AT MATURITY IF THE INDEX CLOSES EITHER ABOVE THE APPLICABLE UPPER INDEX BARRIER OR BELOW THE APPLICABLE LOWER INDEX BARRIER DURING THE OBSERVATION PERIOD.

^¨ 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 any of the stocks underlying the Index or contracts related to the Index. If the Index Ending Level is above the Index Starting Level but the Index closes above the applicable Upper Index Barrier or below the applicable Lower Index Barrier on any trading day during the Observation Period, you will receive only the principal amount of your Notes.

^¨ The Upper Index Barrier and Lower Index Barrier Limit Your Potential Return: The appreciation potential of the Notes is limited to the applicable Upper Index Barrier, if the Index appreciates, and to the applicable Lower Index Barrier, if the Index depreciates, regardless of the performance of the Index.

^¨ 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 underlying the Index 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 agents’ 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, 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.

^¨ 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 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 $0.125 per $10 Note principal amount 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 and may cease any such market making activities at any time. 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 are One of the Companies that Make up the S&P 500^® Index: We are one of the companies that make up the S&P 500^® Index. We will not have any obligation to consider your interests as a holder of the Notes in taking any corporate action that might affect the level of the S&P 500^® Index and the value of 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 Index 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 publish or 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.

readily be foreseen. These factors may include, but are not limited to, economic events, changes in monetary policy, inflation, interest rate volatility, supply and demand for the Notes, market expectations, political, legislative, accounting, tax and other regulatory events, and financial events may either offset or magnify each other and which are described in more detail in product supplement no. 1140-I.

^¨ 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.

^¨ Credit 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.

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 debt instrument that is a “short-term obligation” for U.S. federal income tax purposes. Subject to certain limitations, and based on certain factual representations received from us, in the opinion of Sidley Austin LLP, the Notes will be treated for U.S. federal income tax purposes as debt instruments that constitute “short-term obligations” for U.S. federal income tax purposes.

No statutory, judicial or administrative authority directly addresses the treatment of the Notes or instruments similar thereto for U.S. federal income tax purposes and no ruling will be requested from the Internal Revenue Service with respect to the Notes. As a result, certain aspects of the U.S. federal income tax consequences of an investment in the Notes are uncertain. Any differing treatment could affect the amount, timing and character of income with respect to the Notes.

In general, pursuant to the short-term debt rules, you will be taxed on discount on the Notes. Individuals and certain other cash method holders of the Notes generally are not required to include accrued discount in their income currently unless they elect to do so. Holders that report income for U.S. federal income tax purposes on the accrual method and certain other holders are generally required to accrue discount on the Notes (as ordinary income) on a straight-line basis, unless an election is made to accrue the discount according to a constant yield method based on daily compounding. If a holder is not required, and does not elect, to include discount in income currently, any gain a holder realizes on the sale, exchange or retirement of a Note will generally be ordinary income to the extent of the discount accrued by the holder through the date of sale, exchange or retirement.

Because the amount payable upon maturity of the Notes is not fixed, it is not clear to what extent holders generally required to accrue discount under the short-term debt rules would be required to accrue income with respect to the Notes or the extent to which any gain realized by holders on the sale, exchange or maturity of the Notes would be treated as capital gain or ordinary interest income. Gain realized by a holder who has held the Notes during their entire term to maturity is likely to be treated as ordinary interest income. Any loss realized by such holder upon maturity would likely be treated as capital loss, except possibly to the extent of amounts, if any, previously included in income. You should consult your tax advisors regarding the proper treatment of amounts paid in respect of the Notes.

If you do not elect to currently include accrued discount in income you may be required to defer deductions for a portion of your interest expense with respect to any indebtedness attributable to the Notes.
