MEDIUM-TERM NOTES, SERIES I

12.00% Yield Enhanced Equity Linked Debt Securities Due October 7, 2007

Performance Linked to the Common Stock of KB Home (KBH)

Because these notes are part of a series of Lehman Brothers Holdings’ debt securities called Medium-Term Notes, Series I, this preliminary pricing supplement and the accompanying prospectus supplement, dated May 30, 2006 (the “YEELDS prospectus supplement”) should also be read with the accompanying prospectus supplement, dated May 30, 2006 (the “MTN prospectus supplement”) and the accompanying prospectus dated May 30, 2006 (the “base prospectus”). Terms used here have the meanings given them in the YEELDS prospectus supplement, the MTN prospectus supplement or the base prospectus, unless the context requires otherwise.

· Index stock issuer: KB Home. KB Home is not involved in this offering and has no obligation with respect to the notes.

· Index stock: The common stock of the index stock issuer.

· Principal amount: An amount per YEELDS equal to the initial value, and, in the aggregate, $ .

· Stated maturity date: October 7, 2007, subject to postponement if the valuation date is postponed. If the stated maturity date is not a business day, any payment required to be made on the stated maturity date will instead be made on the next business day with the same effect as if paid on the scheduled stated maturity date, as described on page S-17 of the MTN prospectus supplement.

· Averaging period: The last five scheduled trading days ending on the valuation date (each an “averaging day”), subject to postponement if a market disruption event occurs, as described under “Postponement of an Averaging Day, including Valuation Date, Because of a Market Disruption Event” on page PS-4 of this preliminary pricing supplement.

· Valuation date: October 2, 2007, subject to postponement if a market disruption event occurs or if such day is not a scheduled trading day, as described under “Postponement of an Averaging Day, including Valuation Date, Because of a Market Disruption Event” on page PS-2 of this preliminary pricing supplement.

· Coupon rate: 12.00% per annum, payable quarterly.

· Coupon payment dates: July 7th, 2007 and October 7th, 2007.

· Coupon record dates: 15 calendar days prior to each coupon payment date.

· Payment at maturity: Unless Lehman Brothers Holdings has elected to exercise its stock settlement option described below, on the stated maturity date, Lehman Brothers Holdings will pay you in cash, per YEELDS, the lesser of:
(1) the alternative redemption amount; and
(2) the equity cap price

Because the principal amount is equal to the initial value, the alternative redemption amount per YEELDS will equal the settlement value.

The settlement value will be based upon the arithmetic average of the adjusted closing prices of the index stock on each averaging day during the averaging period, and shall generally be equal to such arithmetic average multiplied by the multiplier, as described beginning on page PS-2 of this preliminary pricing supplement under “Settlement Value Based Upon Arithmetic Average of Adjusted Closing Prices”.

· Stock settlement option: Yes; if Lehman Brothers Holdings has elected to exercise its stock settlement option, on the stated maturity date, Lehman Brothers Holdings will deliver to you, per YEELDS, a number of shares of KB Home common stock equal to the sum of the daily settlement share numbers for each averaging day during the averaging period, all as described beginning on page PS-3 of this preliminary pricing supplement under “Stock Settlement Option”. Lehman Brothers Holdings will provide the trustee with prior written notice no later than the first averaging day if it elects the stock settlement option.

· Denominations: An amount equal to the initial value and integral multiples thereof.

· Listing: The YEELDS will not be listed on any exchange.

· CUSIP No.:

· ISIN No.:

Investing in the notes involves risks. Risk Factors begin on page PS-2 of this preliminary pricing supplement and page SS-7 of the YEELDS prospectus supplement.

ADDITIONAL RISK FACTOR

If a market disruption event occurs on a day that would otherwise be an averaging day, there will be a delay in settlement of the YEELDS.		the YEELDS will be delayed, depending on the circumstances surrounding the market disruption event, for up to 40 trading days following the stated maturity date.

If a market disruption event occurs on a day that would otherwise be an averaging day, settlement of


SETTLEMENT VALUE BASED UPON ARITHMETIC AVERAGE OF ADJUSTED CLOSING PRICES

The settlement value will be based upon the arithmetic average of the adjusted closing prices of the index stock on each of the last five scheduled trading days ending on, and including, the valuation date, and shall generally be equal to such arithmetic average multiplied by the multiplier. Adjustments to the closing prices will occur if KB Home changes the		amount of the quarterly cash dividends it pays on its shares of common stock during the term of the YEELDS. See “Description of the Notes—Settlement value” on page SS-14 in the accompanying YEELDS prospectus supplement.


POSTPONEMENT OF AN AVERAGING DAY, INCLUDING VALUATION DATE, BECAUSE OF A MARKET DISRUPTION EVENT

If a market disruption event occurs on a day that would otherwise be an averaging day, as set forth on the cover page of this pricing supplement, such averaging day will be postponed until the next scheduled trading day on which no market disruption event occurs; provided, however, if a market disruption event occurs on each of the eight scheduled trading days following the originally scheduled averaging day, then (a) that eighth scheduled trading day shall be deemed to be that averaging day and (b) the calculation agent shall determine the adjusted closing price of the index stock for that eighth scheduled trading day, based upon its good faith		estimate of the value of the index stock as of the close of trading on the relevant exchange on such day. If any averaging day is postponed, all subsequent averaging days will also be postponed; the next subsequent averaging day will then be the next scheduled trading day on which no market disruption event occurs (subject to the eight scheduled trading day limitation described above). As a consequence, the occurrence of a market disruption event on a day that would otherwise be an averaging day may result in non-consecutive averaging days.

PS-3

STOCK SETTLEMENT OPTION

If Lehman Brothers Holdings elects to exercise its stock settlement option and provides the trustee with written notice no later than the first averaging day, Lehman Brothers Holdings may, subject to the next paragraph, deliver on the stated maturity date a number of shares of KB Home common stock equal to, per YEELDS, the sum of the daily settlement share numbers for each averaging day during the averaging period, as determined by the calculation agent in its good faith judgment. The daily settlement share number for any averaging day will generally equal:					Upon the occurrence of certain events, or if KB Home is involved in certain extraordinary transactions, the number of shares of KB Home common stock to be delivered may be adjusted and Lehman Brothers Holdings may deliver, in lieu of or in addition to KB Home common stock, cash and any other equity securities used in the calculation of the daily settlement share numbers, all as determined by the calculation agent. See “Description of the Notes—Adjustments to multipliers and to securities included in the calculation of the settlement value” on page SS-16 of the accompanying YEELDS prospectus supplement.

· if the product of the adjusted closing price on such averaging day times the multiplier exceeds the equity cap price:					Because the daily settlement share numbers will ordinarily be determined over the five-trading-day averaging period ending on the fifth business day prior to the stated maturity date, if Lehman Brothers Holdings elects the stock settlement option, the effect to holders will be as if the YEELDS matured over a five trading day period ending on the fifth business day prior to the stated maturity date. Thus, the aggregate value of the shares of KB Home common stock and any other equity securities and cash that you receive at maturity may be more or less than the amount you would have received had Lehman Brothers Holdings not elected the stock settlement option as a result of fluctuations in the value Consequently, it is possible that the aggregate value of the cash and securities that you receive at maturity may be less than the payment that you would have received at maturity had Lehman Brothers Holdings not elected to settle the YEELDS with shares of KB Home common stock. In the absence of any election notice to the trustee, Lehman Brothers Holdings will be deemed to have elected to pay the amount payable at maturity in cash.

		closing price

· if the product of the adjusted closing price on such averaging day times the multiplier is equal to or less than the equity cap price:

0.2 x	adjusted closing price			x multiplier
	closing price

If, however, Lehman Brothers Holdings determines that it is prohibited from delivering such shares, or that it would otherwise be unduly burdensome to deliver such shares, on the stated maturity date, it will pay in cash the amount payable at maturity if it had not elected the stock settlement option.

If the calculation above results in a fractional share, Lehman Brothers Holdings will pay cash to you in an amount equal to that fractional share, calculated on an aggregate basis in respect of the YEELDS you own, multiplied by the market value based upon the arithmetic average of the adjusted closing price of KB Home common stock (and any equity securities included in the calculation of the settlement value) on each averaging day during the five-trading-day averaging period.

PS-4

EXAMPLES OF AMOUNT PAYABLE AT MATURITY

Here are three examples of the amount that may be payable on the stated maturity date if Lehman Brothers Holdings does not elect to exercise its stock settlement option. In each of these examples it is assumed that (a) the investment is held from the date on which the YEELDS are first issued until the stated maturity date, (b) KB Home does not change the amount of the quarterly cash dividends that it pays on its shares of common stock during the term of the YEELDS, (c) the initial value is $43.10 and (d) the equity cap price is $49.5650. Example 1. Assuming the settlement value is $34.48: As a result, because the settlement value of $34.48 is less than $43.10, on the stated maturity date, you would receive $34.48 per YEELDS, plus accrued but unpaid coupon payments. Example 2. Assuming the settlement value is $47.41: As a result, because the settlement value of $47.41 is less than $49.5650, on the stated maturity date, you would receive $47.41 per YEELDS, plus accrued but unpaid coupon payments.		Example 3. Assuming the settlement value is $68.96: As a result, because $49.5650 is less than the settlement value of $68.96, on the stated maturity date, you would receive $49.5650 per YEELDS, plus accrued but unpaid coupon payments. To the extent the actual settlement value, initial value or equity cap price differs from the values assumed above or that KB Home changes the amount of the quarterly cash dividends it pays during the term of the YEELDS, the results indicated above would be different. If Lehman Brothers Holdings elects the stock settlement option, the market price of the shares of KB Home common stock that you receive per YEELDS on the stated maturity date may be less than the amount that you would have received had Lehman Brothers Holdings not elected the stock settlement option because the number of shares you receive will ordinarily be calculated based upon the adjusted closing prices of KB Home common stock during the five-trading-day averaging period ending on the fifth business day prior to the stated maturity date.

(1) Excludes accrued but unpaid coupon payments payable on the stated maturity date.

(2) The hypothetical total annualized yield on the stated maturity date represents the coupon rate per year used in determining the present values, discounted to the original issue date (computed on the basis of a 360-day year of twelve 30-day months compounded annually), of all payments made or to be made on the YEELDS, including the amount payable on the stated maturity date and all coupon payments through the stated maturity date, the sum of these present values being equal to the original issue price.

The above figures are for purposes of illustration only. The actual amount received by investors and the resulting total annualized yield will depend entirely on the actual settlement value determined by the calculation agent. In particular, the actual settlement value could be lower or higher than those reflected in the table.

You should compare the features of the YEELDS to other available investments before deciding to

purchase the YEELDS. Due to the uncertainty concerning the settlement value on the valuation date, the return on investment with respect to the YEELDS may be higher or lower than the return available on other securities issued by Lehman Brothers Holdings or by others. You should reach an investment decision only after carefully considering the suitability of the YEELDS in light of your particular circumstances.

SUPPLEMENTAL PLAN OF DISTRIBUTION

Lehman Brothers Holdings has agreed to sell to Lehman Brothers Inc. and Lehman Brothers Inc. has agreed to purchase, all of the YEELDS at the price indicated on the cover of the pricing supplement. Lehman Brothers Holdings has 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 YEELDS 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. Lehman Brothers Holdings has granted to Lehman Brothers Inc. an option to purchase, at any time within 13 days of the original issuance of the YEELDS, up to additional YEELDS solely to cover over-allotments. To the extent that the option is exercised, Lehman Brothers Inc. will be committed, subject to certain conditions, to purchase the additional YEELDS. If this option is exercised in full, the total public offering price, the underwriting discount and proceeds to Lehman Brothers Holdings would be approximately $ , $ and $ , respectively.		Lehman Brothers Holdings expects to deliver the YEELDS against payment on or about April 5, 2007, which is the fifth business day following the date of the pricing supplement. Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, if any purchaser wishes to trade the YEELDS on the date of the pricing supplement, it will be required, by virtue of the fact that the YEELDS initially will settle on the fifth business day following the date of the pricing supplement, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Lehman Brothers Holdings or an affiliate will enter into swap agreements or related hedge transactions with one of Lehman Brothers Holdings’ other affiliates or unaffiliated counterparties in connection with the sale of the notes and Lehman Brothers Inc. and/or an affiliate will earn additional income as a result of payments pursuant to the swap, or related hedge transactions.
