MSCI has no obligation to consider your interests in calculating or revising the MSCI EM (Emerging Markets) Index. See “The MSCI EM (Emerging Markets) Index.”

Neither Lehman Brothers Holdings nor any of its affiliates assumes any responsibility for the adequacy or accuracy of the information about the MSCI EM (Emerging Markets) Index or MSCI contained in this underlying supplement or any public disclosure of information by MSCI. You, as an investor in the notes, should make your own investigation into the MSCI EM (Emerging Markets) Index and MSCI.

We cannot control actions by the companies whose common stocks or other equity securities make up the MSCI EM (Emerging Markets) Index.

We are not affiliated with any of the companies whose stock is included in the MSCI EM (Emerging Markets) Index. As a result, we will have no ability to control the actions of such companies, including actions that could affect the value of the stocks underlying the MSCI EM (Emerging Markets) Index or your notes. None of the money you pay us will go to MSCI, or any of the companies included in the MSCI EM (Emerging Markets) Index and none of those companies will be involved in the offering of notes in any way.

As a holder of the notes, you will not have voting rights or rights to receive dividends or other distributions or other rights that holders of the securities composing the MSCI EM (Emerging Markets) Index would have.

US-1

Many economic and market factors will impact the value of the notes; these factors interrelate in complex ways and the effect of any one factor may offset or magnify the effect of another factor.

In addition to the price of the stock underlying the MSCI EM (Emerging Markets) Index, 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, including:

• the volatility or expected volatility of each of the stocks underlying the MSCI EM (Emerging Markets) Index;

• the time to maturity of the notes (and any associated “time premium”);

• the dividend rate on the common stocks included in the MSCI EM (Emerging Markets) Index;

• interest and yield rates in the market generally as well as in the markets of the stocks included in the MSCI EM (Emerging Markets) Index;

• economic, financial, political, geographical, agricultural, meteorological, regulatory or judicial events that affect the stocks underlying the MSCI EM (Emerging Markets) Index or markets generally and which may affect the closing prices of the stocks underlying the Index; and

• our creditworthiness, including actual or anticipated downgrades in our credit ratings.

Notes linked to the MSCI EM (Emerging Markets) Index will have exposure to fluctuations in foreign exchange rates.

Because the MSCI EM (Emerging Markets) Index is denominated in U.S. dollars, but its components stocks are denominated in foreign currencies, you will have foreign currency exposure. The value of your notes will be affected by exchange rate fluctuations between the U.S. dollar and the currencies in which the stocks included in the MSCI EM (Emerging Markets) Index are based. Therefore, if the applicable currencies appreciate or depreciate relative to the U.S. dollar over the term of the notes, the value of your notes may increase or decrease at maturity.

The amount payable on the notes at maturity will not be adjusted, unless otherwise specified in the relevant terms supplement, for changes in exchange rates that might affect the MSCI EM (Emerging Markets) Index.

Although the stocks composing the MSCI EM (Emerging Markets) Index are traded in currencies other than U.S. dollars, and the notes, which are linked to the MSCI EM (Emerging Markets) Index, are denominated in U.S. dollars, the amount payable on the notes at maturity will not be adjusted, unless otherwise specified in the relevant terms supplement, for changes in the exchange rate between the U.S. dollar and each of the currencies in which the stocks composing the MSCI EM (Emerging Markets) Index are denominated. Changes in exchange rates, however, may reflect changes in various non-U.S. economies that in turn may affect the amount payable on the notes at maturity. The amount we pay in respect of the notes on the maturity date, if any, will be determined solely in accordance with the procedures described in the relevant product supplement.

An investment in the notes is subject to risks associated with non-U.S. securities markets.

The stocks that constitute the MSCI EM (Emerging Markets) Index have been issued by non-U.S. companies. Investments in securities indexed to the value of such non-U.S. equity securities involve risks associated with the securities markets in those countries, including risks of volatility in those markets, governmental intervention in those markets and cross shareholdings in companies in certain countries. Also, there is generally less publicly available information about companies in some of these jurisdictions than about U.S. companies that are subject to the reporting requirements of the Securities and Exchange Commission, and generally non-U.S. companies are subject to accounting, auditing and financial reporting standards and requirements and securities trading rules different from those applicable to U.S. reporting companies.

US-2

The prices of securities in non-U.S. jurisdictions may be affected by political, economic, financial and social factors in such markets, including changes in a country’s government, economic and fiscal policies, currency exchange laws or other foreign laws or restrictions. Moreover, the economies in such countries may differ favorably or unfavorably from the economy of the United States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources and self sufficiency. Such countries may be subjected to different and, in some cases, more adverse economic environments.

The countries represented by the MSCI EM (Emerging Markets) Index include Argentina, Brazil, Chile, China, Columbia, the Czech Republic, Egypt, Hungary, India, Indonesia, Israel, Jordan, Malaysia, Mexico, Morocco, Pakistan, Peru, Philippines, Poland, Russia, South Africa, South Korea, Taiwan, Thailand and Turkey. Countries with emerging markets may have relatively unstable governments; may present risks of nationalization of businesses; may impose restrictions on foreign ownership, foreign currency exchange and the repatriation of assets; and may be less protective of property rights than more developed countries. The economies of countries with emerging markets may be based on only a few industries, may be highly vulnerable to changes in local, regional and global economic and trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.

Time differences between the cities where the stocks underlying the MSCI EM (Emerging Markets) Index trade and New York City may create discrepancies in trading levels.

As a result of the time difference between the cities where the stocks underlying the MSCI EM (Emerging Markets) Index trade and New York City (where the notes may trade), there may be discrepancies between the prices of the stocks underlying the MSCI EM (Emerging Markets) Index and the trading prices of the notes. In addition, there may be periods when the foreign securities markets are closed for trading (for example during holidays in a foreign country), as a result of which the prices of the stocks underlying the MSCI EM (Emerging Markets) Index remain unchanged for multiple trading days in New York City.

MSCI EM (Emerging Markets) Index Composition and Calculation

The MSCI EM (Emerging Markets) Index (the “Index”) is a free float-adjusted market capitalization index that is designed to measure the performance of certain equity market performance of emerging markets. It has a base date of December 31, 1987 and had on that date an initial value of 100. The MSCI EM (Emerging Markets) Index is calculated in U.S. dollars on a real time basis and disseminated every 60 seconds during market trading hours.

As of January 15, 2008, the Index consisted of the following 25 emerging market country indices: Argentina, Brazil, Chile, China, Colombia, Czech Republic, Egypt, Hungary, India, Indonesia, Israel, Jordan, Malaysia, Mexico, Morocco, Pakistan, Peru, Philippines, Poland, Russia, South Africa, South Korea, Taiwan, Thailand and Turkey. As of January 15, 2008 the five largest sector weights were: Financials (21.7%), Energy (18.2%), Materials (15.2%), Telecommunication Services (11.4%) and Information Technology (9.6%). The Index contained 926 constituents with a total market capitalization of US$3,503,422 million.

The Index is part of the MSCI Equity Indices series. MSCI aims to include in its indices 85% of the free float-adjusted market capitalization in each industry sector, within each country included in an index.

MSCI recently announced changes to the methodology used in its MSCI International Equity Indices. The current MSCI Standard and MSCI Small Cap Indices, along with the other MSCI equity indices based on them, are transitioning to the Global Investable Market Indices methodology described below. The first phase of the transition of the MSCI Standard Indices, which include the MSCI EM (Emerging Markets) Index, was completed on November 30, 2007. At the end of the transition period (May 30, 2008), the current MSCI Standard Indices will be composed of the MSCI Large Cap and Mid Cap Indices. The current MSCI Small Cap Index will transition to the MSCI Small Cap Index resulting from the new methodology. Together, the relevant MSCI Large Cap, Mid Cap and Small Cap Indices will make up the MSCI Investable Market Index for each country, composite, sector, and style index that MSCI offers.

Constructing the MSCI Global Investable Market Indices

MSCI undertakes an index construction process, which involves: (i) defining the Equity Universe; (ii) determining the Market Investable Equity Universe for each market; (iii) determining market capitalization size segments for each market; (iv) applying Index Continuity Rules for the MSCI Standard Index; (v) creating style segments within each size segment within each market; and (vi) classifying securities under the Global Industry Classification Standard (the “GICS”).

US-4

Defining the Equity Universe

(i) Identifying Eligible Equity Securities: The Equity Universe initially looks at securities listed in any of the countries in the MSCI Global Index Series, which will be classified as either Developed Markets (“DM”) or Emerging Markets (“EM”). All listed equity securities, or listed securities that exhibit characteristics of equity securities, except mutual funds, ETFs, equity derivatives, limited partnerships, and most investment trusts, are eligible for inclusion in the Equity Universe. Real Estate Investment Trusts (“REITs”) in some countries and certain income trusts in Canada are also eligible for inclusion.

(ii) Country Classification of Eligible Securities: Each company and its securities (i.e., share classes) are classified in one and only one country, which allows for a distinctive sorting of each company by its respective country.

Determining the Market Investable Equity Universes

A Market Investable Equity Universe for a market is derived by applying investability screens to individual companies and securities in the Equity Universe that are classified in that market. A market is equivalent to a single country, except in DM Europe, where all DM countries in Europe are aggregated into a single market for index construction purposes. Subsequently, individual DM Europe country indices within the MSCI Europe Index are derived from the constituents of the MSCI Europe Index under the Global Investable Market Indices methodology.

The investability screens used to determine the Investable Equity Universe in each market are as follows:

(i) Equity Universe Minimum Size Requirement: This investability screen is applied at the company level. In order to be included in a Market Investable Equity Universe, a company must have the required minimum full market capitalization.

(ii) Equity Universe Minimum Float-Adjusted Market Capitalization Requirement: This investability screen is applied at the individual security level. To be eligible for inclusion in a Market Investable Equity Universe, a security must have a free float-adjusted market capitalization equal to or higher than 50% of the Equity Universe Minimum Size Requirement.

(iii) DM and EM Minimum Liquidity Requirement: This investability screen is applied at the individual security level. To be eligible for inclusion in a Market Investable Equity Universe, a security must have adequate liquidity. The Annualized Traded Value Ratio (“ATVR”), a measure that offers the advantage of screening out extreme daily trading volumes and taking into account the free float-adjusted market capitalization size of securities, is used to measure liquidity. In the calculation of the ATVR, the trading volumes in depository receipts associated with that security, such as ADRs or GDRs, are also considered. A minimum liquidity level of 20% ATVR is required for inclusion of a security in a Market Investable Equity Universe of a Developed Market, and a minimum liquidity level of 15% ATVR is required for inclusion of a security in a Market Investable Equity Universe of an Emerging Market.

(iv) Global Minimum Foreign Inclusion Factor Requirement: This investability screen is applied at the individual security level. To be eligible for inclusion in a Market Investable Equity Universe, a security’s Foreign Inclusion Factor (“FIF”) must reach a certain threshold. The FIF of a security is defined as the proportion of shares outstanding that is available for purchase in the public equity markets by international investors. This proportion accounts for the available free float of and/or the foreign ownership limits applicable to a specific security (or company). In general, a security must have an FIF equal to or larger than 0.15 to be eligible for inclusion in a Market Investable Equity Universe.

(v) Minimum Length of Trading Requirement: This investability screen is applied at the individual security level. For an initial public offering (“IPO”) to be eligible for inclusion in a Market Investable Equity Universe, the new issue must have started trading at least four months before the implementation of the initial construction of the index or at least three months before the

US-5

implementation of a Semi-Annual Index Review. This requirement is applicable to small new issues in all markets. Large IPOs are not subject to the Minimum Length of Trading Requirement and may be included in a Market Investable Equity Universe and the Standard Index outside of a Quarterly or Semi-Annual Index Review.

Defining Market Capitalization Size Segments for Each Market

Once a Market Investable Equity Universe is defined, it is segmented into the following size-based indices:

• Investable Market Index (Large + Mid + Small)

• Standard Index (Large + Mid)

• Large Cap Index

• Mid Cap Index

• Small Cap Index

Creating the Size Segment Indices in each market involves the following steps: (i) defining the Market Coverage Target Range for each size segment; (ii) determining the Global Minimum Size Range for each size segment; (iii) determining the Market Size-Segment Cutoffs and associated Segment Number of Companies; (iv) assigning companies to the size segments; and (v) applying final size-segment investability requirements.

Index Continuity Rules for the Standard Indices

In order to achieve index continuity, as well as provide some basic level of diversification within a market index, notwithstanding the effect of other index construction rules contained herein, a minimum number of five constituents will be maintained for a DM Standard Index and a minimum number of three constituents will be maintained for an EM Standard Index.

Creating Style Indices within Each Size Segment

All securities in the investable equity universe are classified into Value or Growth segments using the MSCI Global Value and Growth methodology.

Classifying Securities under the Global Industry Classification Standard

All securities in the Global Investable Equity Universe are assigned to the industry that best describes their business activities. To this end, MSCI has designed, in conjunction with Standard & Poor’s, the Global Industry Classification Standard. Under the GICS, each company is assigned uniquely to one sub-industry according to its principal business activity. Therefore, a company can belong to only one industry grouping at each of the four levels of the GICS.

MSCI EM (Emerging Markets) Index Maintenance

The MSCI Global Investable Market Indices are maintained with the objective of reflecting the evolution of the underlying equity markets and segments on a timely basis, while seeking to achieve index continuity, continuous investability of constituents and replicability of the indices, and index stability and low index turnover.

In particular, index maintenance involves:

(i) Semi-Annual Index Reviews (“SAIRs”) in May and November of the Size Segment and Global Value and Growth Indices which include:

• Updating the indices on the basis of a fully refreshed Equity Universe.

US-6

• Taking buffer rules into consideration for migration of securities across size and style segments.

• Updating FIFs and Number of Shares (“NOS”).

(ii) Quarterly Index Reviews (“QIRs”) in February and August of the Size Segment Indices aimed at:

• Including significant new eligible securities (such as IPOs that were not eligible for earlier inclusion) in the index.

• Allowing for significant moves of companies within the Size Segment Indices, using wider buffers than in the SAIR.

• Reflecting the impact of significant market events on FIFs and updating NOS.

(iii) Ongoing event-related changes. Changes of this type are generally implemented in the indices as they occur. Significantly large IPOs are included in the indices after the close of the company’s tenth day of trading.

Transition

MSCI will transition the current MSCI Standard Index, the Small Cap Index and all indices derived from the MSCI Standard Index to the Global Investable Market Indices methodology described above.

All indices that are constructed with the Standard Indices as their basis, such as the GDP-weighted indices, 10/40 Indices and other custom indices, High Dividend Yield Indices, the MSCI Global Value and Growth Indices, etc., will continue to be derived from the Standard Indices throughout the transition.

The second phase of the transition of the MSCI Standard and the MSCI Small Cap Indices to the MSCI Global Investable Market Indices methodology will take place on May 30, 2008 (the first phase having been completed on November 30, 2007). The final additions and deletions of constituents for the second phase will be announced at least four weeks in advance of their implementation in the Standard and Small Cap Indices. All indices derived from the MSCI Standard Indices will follow the two-phase transition, except for the MSCI Euro and Pan Euro Indices which were transitioned in one phase on November 30, 2007. The transition will be synchronized for all markets and composites.

During the transition period, MSCI will be producing the MSCI Provisional Standard and Provisional Small Cap Indices to assist investors in understanding the changes that would occur if the Global Investable Market Indices methodology were immediately implemented in the current MSCI Standard and Small Cap Indices. The Provisional Indices also provide increased flexibility to current investors who wish to transition to the Global Investable Market Indices methodology on their own schedule.

The Provisional Standard and Provisional Small Cap Indices and the new Size Segment and Style Indices that will be created based on this methodology are official MSCI indices and, as such, can be used for a variety of purposes, including as the basis for new investment mandates and for investment vehicles such as passive mutual funds, exchange traded funds and listed and over-the-counter derivative contracts.

Reflecting Constituent Changes in the Standard Indices at the Transition Points

In the first phase of the transition, which was completed on November 30, 2007:

• After rebalancing the Provisional Standard Indices as per the SAIR, they were compared with the relevant Standard Indices.

US-7

• All companies that were in the Provisional Standard Index but not in the corresponding Standard Index were added to the Standard Index at half of their free float-adjusted market capitalization, and all companies that were not in the Provisional Standard Index but were in the corresponding Standard Index were retained in the Standard Index but at only half of their free float-adjusted market capitalization.

In the second and final phase in May 2008:

• The Provisional Standard Indices will be rebalanced.

• Any and all differences between the rebalanced Provisional Standard Index and the Standard Index will be fully implemented in the Standard Indices.

The transition of the Small Cap Indices will be synchronized with the transition of the Standard Indices, following the same timeline and approach.

Discontinuation of the MSCI EM (Emerging Markets) Index; Alteration of Method of Calculation

MSCI has no obligation to continue to publish the MSCI EM (Emerging Markets) Index, and may discontinue publication of the MSCI EM (Emerging Markets) Index at any time in its sole discretion. If MSCI discontinues publication of the MSCI EM (Emerging Markets) Index and MSCI or another entity publishes a successor or substitute index that the calculation agent determines, in its sole discretion, to be comparable to the discontinued Index (such index being referred to herein as a “MSCI EM (Emerging Markets) Index successor index”), then any Index closing level will be determined by reference to the level of such MSCI EM (Emerging Markets) Index successor index at the close of trading on the NYSE, the AMEX, the NASDAQ National Market or the relevant exchange or market for the MSCI EM (Emerging Markets) Index successor index on each relevant Index Valuation Date, Observation Date, Averaging Date, Review Date or other relevant date or dates as set forth in the relevant terms supplement.

Upon any selection by the calculation agent of a MSCI EM (Emerging Markets) Index successor index, the calculation agent will cause written notice thereof to be promptly furnished to the trustee, to us and to the holders of the notes.

If MSCI discontinues publication of the MSCI EM (Emerging Markets) Index prior to, and such discontinuation is continuing on, an Index Valuation Date, Observation Date, Averaging Date, Review Date or other relevant date as set forth in the relevant terms supplement, and the calculation agent determines, in its sole discretion, that no MSCI EM (Emerging Markets) Index successor index is available at such time, or the calculation agent has previously selected a MSCI EM (Emerging Markets) Index successor index and publication of such MSCI EM (Emerging Markets) Index successor index is discontinued prior to, and such discontinuation is continuing on, such Index Valuation Date, Observation Date, Averaging Date, Review Date or other relevant date, or if MSCI (or the publisher of any MSCI EM (Emerging Markets) Index successor index) fails to calculate and publish a closing level for the MSCI EM (Emerging Markets) Index (or any MSCI EM (Emerging Markets) Index successor index) on any date when it would ordinarily do so in accordance with its customary practice, then the calculation agent will determine the Index closing level for such date. The Index closing level will be computed by the calculation agent in accordance with the formula for and method of calculating the MSCI EM (Emerging Markets) Index or MSCI EM (Emerging Markets) Index successor index, as applicable, last in effect prior to such discontinuation, or failure to calculate or publish a closing level for the index, using the closing price (or, if trading in the relevant securities has been materially suspended or materially limited, its good faith estimate of the closing price that would have prevailed but for such suspension or limitation) at the close of the principal trading session on such date of each security most recently composing the MSCI EM (Emerging Markets) Index or MSCI EM (Emerging Markets) Index successor index, as applicable. Notwithstanding these alternative arrangements, discontinuation of the publication or failure to calculate or publish the closing level of the MSCI EM (Emerging Markets) Index may adversely affect the value of the notes.

US-8

As used herein, “closing price” of a security, on any particular day, means the last reported sales price for that security on the relevant exchange at the scheduled weekday closing time of the regular trading session of the relevant exchange. If, however, the security is not listed or traded on a bulletin board, then the closing price of the security will be determined using the average execution price per share that an affiliate of Lehman Brothers Holdings Inc. pays or receives upon the purchase or sale of the security used to hedge Lehman Brothers Holdings Inc.’s obligations under the notes. The “relevant exchange” for any security (or any combination thereof then underlying the MSCI EM (Emerging Markets) Index or any successor index) means the primary exchange, quotation system (which includes bulletin board services) or other market of trading for such security.

If at any time the method of calculating the MSCI EM (Emerging Markets) Index or a MSCI EM (Emerging Markets) Index successor index, or the level thereof, is changed in a material respect, or if the MSCI EM (Emerging Markets) Index or a MSCI EM (Emerging Markets) Index successor index is in any other way modified so that the MSCI EM (Emerging Markets) Index or such MSCI EM (Emerging Markets) Index successor index does not, in the opinion of the calculation agent, fairly represent the level of the MSCI EM (Emerging Markets) Index or such MSCI EM (Emerging Markets) Index successor index had such changes or modifications not been made, then the calculation agent will, at the close of business in New York City on each date on which the MSCI EM (Emerging Markets) Index closing level is to be determined, make such calculations and adjustments as, in the good faith judgment of the calculation agent, may be necessary in order to arrive at a level of a stock index comparable to the MSCI EM (Emerging Markets) Index or such MSCI EM (Emerging Markets) Index successor index, as the case may be, as if such changes or modifications had not been made, and the calculation agent will calculate the Index closing level with reference to the MSCI EM (Emerging Markets) Index or such MSCI EM (Emerging Markets) Index successor index, as adjusted. Accordingly, if the method of calculating the MSCI EM (Emerging Markets) Index or a MSCI EM (Emerging Markets) Index successor index is modified so that the level of the MSCI EM (Emerging Markets) Index or such MSCI EM (Emerging Markets) Index successor index is a fraction of what it would have been if there had been no such modification (e.g., due to a split in the MSCI EM (Emerging Markets) Index), then the calculation agent will adjust its calculation of the MSCI EM (Emerging Markets) Index or such MSCI EM (Emerging Markets) Index successor index in order to arrive at a level of the MSCI EM (Emerging Markets) Index or such MSCI EM (Emerging Markets) Index successor index as if there had been no such modification (e.g., as if such split had not occurred).

License Agreement with MSCI

Lehman Brothers Holdings Inc. is expected to enter into a non-exclusive license agreement with MSCI, which would grant Lehman Brothers Holdings Inc. and certain of its affiliated or subsidiary companies a license, in exchange for a fee, to use the MSCI EM (Emerging Markets) Index in connection with certain products, including the notes.

ALTHOUGH MSCI SHALL OBTAIN INFORMATION FOR INCLUSION IN OR FOR USE IN THE CALCULATION OF THE INDEX FROM SOURCES THAT MSCI CONSIDERS RELIABLE, NEITHER MSCI NOR ANY OTHER PARTY GUARANTEES THE ACCURACY AND/OR COMPLETENESS OF THE INDEX OR ANY DATA INCLUDED THEREIN.
