Investor Suitability

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

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

^¨ 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.

Term	4 years
Basket	The Notes are linked to a Basket consisting of the S&P 500® Index (SPX), the Dow Jones EURO STOXX 50® Index (SX5E) and the Nikkei 225SM Index (NKY) (each, a “Basket Index” and, collectively, the “Basket Indices”).
Index Weightings	S&P 500® Index Dow Jones EURO STOXX 50® Index Nikkei 225SM Index	33.34% 33.33% 33.33%
Participation Rate	105% to 115%. The actual Participation Rate will be determined on the Trade Date.
Principal Protection	100% if held to maturity
Payment at Maturity (per $10)	If the Basket Return is positive, you will receive a cash payment, for each $10 Note principal amount, of $10 plus the Additional Amount, which will be calculated as follows: $10 x Basket Return x Participation Rate If the Basket Return is zero or negative, you will receive a cash payment, for each $10 principal amount Note, of $10.

Determining Payment at Maturity

The percentage change from the Basket Starting Level to the Basket Ending Level

You will receive a cash payment that provides you with a return per $10 Note principal amount equal to the Basket Return multiplied by the Participation Rate of 105% to 115% (actual Participation Rate to be set on the Trade Date). Accordingly, if the Basket Return is positive, your payment at maturity per $10 Note principal amount will be calculated as follows: $10 + [$10 x Basket Return x Participation Rate]

You will receive the principal amount of your Notes 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 a Participation Rate of 110%, the midpoint of the range of 105% to 115%, and assume a range of Basket Returns from +40% to -40%. 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 110. Because the Basket Ending Level is 110 and the Basket Starting Level is 100, the Basket Return is 10% calculated as follows:

(110 – 100)/100 = 10%

Because the Basket Return is 10%, the Additional Amount is equal to $1.10 and the payment at maturity is equal to $11.10 per $10.00 principal amount Note calculated as follows:

$10 + ($10 × 10% × 110%) = $11.10

Example 2—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 Additional Amount is equal to $0 and the payment at maturity is equal to $10 per $10 principal amount Note.

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 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 $10 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, and the adjustments thereto, in respect of the Notes. See “Certain U.S. Federal Income Tax Consequences” in product supplement no. 220-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. 220-I and in the “Risk Factors” section of the accompanying underlying supplement no. 720. 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 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 weighted basket composed of the Basket Indices. At a time when the level of one or more Basket Indices increases, the level of the other Basket Index or 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: 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 Dow Jones EURO STOXX 50^® Index and the Nikkei 225^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 the Notes instead of other investments. We will pay compensation of $0.30 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 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 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 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 S&P 500^® Index, Dow Jones EURO STOXX 50^® Index, or Nikkei 225^SM Index. 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 recently published research or other opinions that are inconsistent with an investment position in S&P 500^® Index, Dow Jones EURO STOXX 50^® Index, or Nikkei 225^SM Index. 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 product supplement no. 220-I.

Hypothetical Historical Basket Performance

The graph below illustrates the hypothetical historical performance of the Basket from July 11, 1997 to July 13, 2007, if the Basket Level was made to equal 100 on July 13, 2007. The hypothetical historical performance reflects the performance the Basket would have exhibited based on (i) the actual historical performance of the Basket Indices and (ii) the Basket Weightings indicated in the Indicative Terms. Neither the hypothetical historical performance of the Basket nor the actual historical performance of the Basket Indices should be taken as indications of future performance.
