INITIAL MULTIPLIERS; ADJUSTMENTS TO THE MULTIPLIERS; BASE DIVIDENDS

The initial multiplier is:

· 1.42011 for the Intersil Corporation common stock; · 1.27701 for the Seagate Technology common stock; and · 1.92828 for the Fairchild Semiconductor International Inc. common stock. The multipliers are subject to adjustment under certain circumstances, including if, during the period from the date of this pricing supplement to the valuation date, holders of record of shares of common stock of any of the three companies whose common stock is included in the basket are entitled to receive a cash dividend (other than an extraordinary dividend) from such company and the amount of such dividend is more or less than the “base dividend” specified below.  See “Description of the Notes—Adjustments to multipliers and securities included in the calculation of the settlement value” on page SS-19 of the synthetic convertible prospectus supplement. The “base dividend” shall be: ·    $0.06 for the Intersil Corporation common stock; ·    $0.10 for the Seagate Technology common stock; and ·    $0.00 for the Fairchild Semiconductor International Inc. common stock;

which is the amount of the respective dividend per share of common stock most recently paid by such company prior to the date of this pricing supplement, subject to adjustment in the event of certain events affecting the applicable shares of common stock of any such company, such as share splits, reverse share splits or reclassifications, as determined by the calculation agent, in its good faith judgment. If the calculation agent determines in its sole and absolute discretion that any such company has failed to declare or make a dividend payment, the effective adjustment date for adjusting the applicable multiplier will be: ·      in the case of the Intersil Corporation common stock, the first business day immediately following the 19th day of each January, April, July or October and the valuation date, as applicable; ·      in the case of Seagate Technology common stock, the first business day immediately following the 19th day of each January, April, July or October and the valuation date, as applicable; and ·      in the case of the Fairchild Semiconductor International Inc. common stock, the first business day immediately following the 19th day of each January, April, July or October  and the valuation date, as applicable.

EXAMPLES OF AMOUNT PAYABLE AT MATURITY OR UPON REDEMPTION OR REPURCHASE

Here are two examples of hypothetical alternative redemption amount calculations.  In each of these examples it is assumed that during the term of the notes the issuers of the common stocks included in the basket do not change the amount of the cash dividends that they pay on their shares of common stock. Example 1. Assuming the settlement value is $83.90: Alternative redemption amount per $1,000 note = $1,000  ×        $83.90    =   $749.98 $111.87 As a result, on the maturity date, or upon redemption, you would receive $1,000, plus accrued but unpaid interest, per $1,000 note because $1,000 is greater than $749.98.  If you require Lehman Brothers Holdings to repurchase your notes, you would only receive $749.98, plus accrued but unpaid interest, per $1,000 note. Example 2. Assuming the settlement value is $139.84: Alternative redemption amount per $1,000 note = $1,000  ×            $139.84     =    $1,250.02 $111.87 As a result, on the maturity date or upon redemption, you would receive $1,250.02, plus accrued but unpaid interest, per $1,000 note because $1,250.02 is greater than $1,000. If you require Lehman Brothers Holdings to repurchase your notes, you would also receive $1,250.02, plus accrued but unpaid interest, per $1,000 note. To the extent the actual settlement value differs from the values assumed above or that any of the issuers of the common stocks included in the basket changes the amount of the cash dividends it pays on its shares of common stock, the results indicated above would be different.

HYPOTHETICAL RETURNS
The table below illustrates, for a range of hypothetical settlement values on the valuation date, in each case assuming that (a) the investment is held from the date on which the notes are first issued until the stated maturity date and (b) the issuers of the common stocks included in the basket do not change the amount of the cash dividends that they pay on their shares of common stock:	·  the hypothetical total amount payable on the stated maturity date per $1,000 note (without interest); ·  the hypothetical total rate of return (without interest); ·  the hypothetical annualized pre-tax rate of return (without interest);
·  the hypothetical alternative redemption amount per $1,000 note;	·  the hypothetical total rate of return (including interest); and

(1)This figure represents the threshold level.

The above figures are for purposes of illustration only. The actual amount received by investors and the resulting total and pre-tax rates of return 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. The table above only provides hypothetical return information with regard to notes held to maturity.  It is not applicable in the case of notes repurchased or redeemed prior to the stated maturity date. You should compare the features of the notes to other available investments before deciding to purchase the notes. Due to the uncertainty as to whether the alternative redemption amount, at stated maturity or in connection with a repurchase or redemption, will be greater than $1,000 per $1,000 note or whether the notes will be redeemed prior to the stated maturity date, the return on investment with respect to the notes may be higher or lower than the return available on other securities issued by Lehman Brothers Holdings or by others and available through Lehman Brothers Inc. You should reach an investment decision only after carefully considering the suitability of the notes in light of your particular circumstances.

SUPPLEMENTAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

Lehman Brothers Holdings 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 actual interest payments on the notes and estimates the amount and timing of contingent payments on the notes. Lehman Brothers Holdings has determined that the comparable yield is an annual rate of 5.4440% compounded semi-annually. Based on the comparable yield, the projected payment schedule per $1,000 note is $1.25 semi-annually and $1,436.72 due at maturity. Lehman Brothers Holdings agrees and, by purchasing a note, you agree, for United States federal income tax purposes, to be bound by Lehman Brothers Holdings’ 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 and the projected payments set forth in the projected payment schedule prepared by Lehman Brothers Holdings in determining your interest accruals, and the adjustments thereto, in respect of the notes. See “United States Federal Income Tax Consequences” in the accompanying synthetic convertible prospectus supplement.

PS-10

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 notes at the price indicated on the cover of this 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 notes initially at a public offering price equal to the issue price set forth on the cover of this 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 notes, up to $2,550,000 additional aggregate principal amount of notes 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 notes.  If this option is exercised in full, the total public offering price, the underwriting discount and proceeds to Lehman Brothers Holdings would be $19,550,000, $25,415 and $19,524,585, respectively. Lehman Brothers Holdings expects to deliver the notes against payment on or about January 26, 2007, which is the fifth business day following the date of this 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 notes on the date of this pricing supplement, it will be required, by virtue of the fact that the notes initially will settle on the fifth business day following the date of this 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 has entered 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 has earned additional income as a result of payments pursuant to the swap, or related hedge transactions.
