CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

We intend to treat the Notes as contingent payment debt instruments, as described under “Supplemental United States Federal Income Tax Consequences—Contingent Payment Debt Instruments” in the Prospectus.

HISTORICAL LEVELS OF THE 30-YEAR CMS RATE AND THE 10-YEAR CMS RATE

The following shows for illustrative purposes the 30-Year CMS Rate and the 10-Year CMS Rate in effect on the Trade Date and on the hypothetical Interest Reset Dates listed below. The historical experience of the 30-Year CMS Rate and 10-Year CMS Rate should not be taken as an indication of the future performance of the 30-Year CMS Rate and 10-Year CMS Rate during the term of the Notes. Fluctuations in the level of the 30-Year CMS Rate and 10-Year CMS Rate make the Notes’ effective interest rate after January 25, 2008, difficult to predict and can result in effective interest rates to investors that are lower than anticipated. In addition, historical interest rates are not necessarily indicative of future interest rates. Fluctuations in interest rates and interest rate trends that have occurred in the past are not necessarily indicative of fluctuations that may occur in the future, which may be wider or narrower than those that have occurred historically.

SUPPLEMENTAL INFORMATION CONCERNING THE PLAN OF DISTRIBUTION

Lehman Brothers Holdings has agreed to sell to Lehman Brothers Inc. (the “Agent”), and the Agent has agreed to purchase from Lehman Brothers Holdings Inc. the principal amount of the Notes at the price specified on the cover of this pricing supplement. The Agent is committed to take and pay for all of the Notes, if any are taken.

The Agent proposes to offer the Notes from time to time for sale in negotiated transactions, or otherwise, at varying prices to be determined at the time of each sale. In connection with the sale

of the Notes, the Agent may be deemed to have received compensation from us in the form of underwriting discounts. The Agent may effect such transactions by selling the Notes to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the Agent.

It is expected that delivery of the Notes will be made against payment therefor more than three business days following the date of this pricing supplement. 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, purchasers who wish to trade the securities on any day prior to the third business day before the settlement date will be required to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement.

If the Notes are sold in a market-making transaction after their initial sale, information about the purchase price and the date of the sale will be provided in a separate confirmation of sale.
