RISK FACTORS

An investment in the Notes entails certain risks not associated with an investment in conventional floating rate or fixed rate medium-term notes. See “Risk Factors” in the Prospectus Supplement.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

We intend to treat the Notes as variable rate debt instruments, as described under “Supplemental United States Federal Income Tax Consequences—Variable Rate Debt Instruments” in the Prospectus Supplement.

HISTORICAL LEVELS OF THE 10-YEAR CMS RATE AND THE 2-YEAR CMS RATE

The following shows the 10-Year CMS Rate and the 2-Year CMS Rate in effect on the Trade Date and on the hypothetical Interest Reset Dates listed below. The historical experience of the 10-Year CMS Rate and 2-Year CMS Rate should not be taken as an indication of the future performance of the 10-Year CMS Rate and 2-Year CMS Rate during the term of the Notes. Fluctuations in the level of the 10-Year CMS Rate and 2-Year CMS Rate make the Notes’ effective interest rate after June 2, 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 Inc. 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. The Agent may also use all or a portion of its commissions on the Notes to pay selling concessions or fees to other dealers not to exceed 2.00%.

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.
