Security Offerings

We are offering 100% Principal Protection Notes Linked to a Currency Basket. If the Basket Return, which is linked to the performance of the Basket relative to the U.S. dollar, is greater than zero on the Valuation Date, the investor will receive a single payment at maturity equal to the principal amount of the Notes plus an Additional Amount equal to the principal amount of the Notes multiplied by the product of [235–275%] (the Participation Rate) and the appreciation of the Basket (that is, the amount by which the Basket Return exceeds zero). If the Basket Return on the Valuation Date is less than or equal to zero, then the investor will receive at maturity only the principal amount of the Notes, with no additional return. The Notes do not bear interest and are 100% principal protected if held to maturity. The Notes are offered at a minimum investment of $1,000.

Scenario Analysis and Examples at Maturity

The following examples for the Notes shows scenarios for the Payment at Maturity of the Notes, assuming a Participation Rate of 250% and hypothetical Basket Returns from –100% to +100%. The actual Participation Rate will be set on the Trade Date.

Example A—The level of the Basket increases from the Basket Starting Level of 100 to a Basket Ending Level of 110. Because the Basket Ending Level is 110 and the Basket Starting Level is 100, the Basket Return is 10%, calculated as follows:

(110 – 100)/100 = 10%

Because the Basket Return is 10%, the Additional Amount is equal to $2.50, a return of 25% per $10 Note, and the payment at maturity is equal to $12.50 per $10 Note, calculated as follows:

$10 + ($10 × 10% × 250%) = $12.50

Example B—The level of the Basket decreases from the Basket Starting Level of 100 to a Basket Ending Level of 90. Because the Basket Ending Level is 90 and the Basket Starting Level is 100, the Basket Return is –10% calculated as follows:

(90 – 100)/100 = –10%

Because the Basket Return is –10%, the Additional Amount is equal to $0, a return of 0% per $10 Note, and the payment at maturity is equal to $10 per $10 Note.

For additional payment examples for the Notes showing scenarios for the Payment at Maturity of the Notes, showing positive and negative Basket Ending Levels and Basket Returns (based on either correlated or offsetting appreciation and depreciation in the different Basket Currencies), see “Additional Payment at Maturity Examples” below.

Disruption Events	If a Disruption Event relating to one or more Basket Currencies is in effect on the scheduled Valuation Date, the Calculation Agent will calculate the Basket Return using: •    for each Basket Currency that did not suffer a Disruption Event on the scheduled Valuation Date, the Final Spot Rate on the scheduled Valuation Date, and •    for each Basket Currency that did suffer a Disruption Event on the scheduled Valuation Date, the Final Spot Rate on the immediately succeeding scheduled Valuation Business Day for such Basket Currency on which no Disruption Event occurs or is continuing with respect to such Basket Currency; provided however that if a Disruption Event has occurred or is continuing with respect to a Basket Currency on each of the three scheduled Valuation Business Days following the scheduled Valuation Date, then (a) such third scheduled Valuation Business Day shall be deemed the Valuation Date for the affected Basket Currency; and (b) the Calculation Agent will determine the Final Spot Rate for the affected Basket Currency on such day in accordance with “Fallback Rate Observation Methodology” (as defined under “Description of the Notes—Currency-Indexed Notes” in the MTN Prospectus Supplement). A “Disruption Event” means any of the following events with respect to a Basket Currency, as determined in good faith by the Calculation Agent: (A)   the occurrence and/or existence of an event on any day that has the effect of preventing or making impossible the delivery of USD from accounts inside the Basket Currency Jurisdiction for that Basket Currency to accounts outside that Basket Currency Jurisdiction; (B)    the occurrence of any event causing the Reference Exchange Rate for the Basket Currency to be split into dual or multiple currency exchange rates; or (C)   the Final Spot Rate being unavailable for the Basket Currency, or the occurrence of an event (i) in the Basket Currency Jurisdiction for that Basket Currency that materially disrupts the market for the Basket Currency or (ii) that generally makes it impossible to obtain the Final Spot Rate for the Basket Currency, on the Valuation Date.

What are the tax consequences of the Notes?

Lehman Brothers Holdings Inc. intends to treat, and by purchasing a note for all tax purposes you agree 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 MTN Prospectus Supplement.

Key Risks

An investment in the Notes entails certain risks not associated with an investment in conventional floating rate or fixed rate medium-term Notes. You should read the risks summarized below in conjunction with, and the risks summarized below are qualified by reference to, the risks described in “Risk Factors” generally, and “Risk Factors—Risks Relating to Currency Indexed Notes” in particular, in the MTN Prospectus Supplement. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the Notes. You should reach an investment decision only after you and your advisors have carefully considered the suitability of an investment in the Notes in light of your particular circumstances.

^¨ No interest payments — The terms of the Notes differ from those of ordinary debt securities in that the Issuer will not pay interest on the Notes. The return on the Notes at maturity is entirely dependent on the aggregate performance of the Basket Currencies, and if the Basket Return is zero or less than zero, you will receive only the repayment of your principal, with no additional return.

^¨ Principal protection only if you hold the Notes to maturity — The trading value of the Notes will be affected by factors that interrelate in complex ways, including (but not limited to) the prevailing exchange rates of the Basket Currencies relative to the U.S. dollar from time to time (as discussed under “Foreign Exchange Rate Risk” below). Although the Notes are principal-protected if held to maturity, selling this or any fixed income security prior to maturity may result in a dollar price less than 100% of the applicable principal amount of Notes sold.

^¨ Foreign exchange rate risk — An investment in the Notes may not be suitable for an investor unfamiliar with the exchange rates of the Basket Currencies relative to the U.S. dollar or the factors that affect movements in such exchange rates. The exchange rates for the Basket Currencies relative to the U.S. dollar will be influenced by the complex and interrelated global and regional political, economic, financial and other factors that can affect the currency markets on which a Basket Currency is traded. Changes in the exchange rates for the Basket Currencies result over time from the interaction of many factors directly or indirectly affecting economic and political conditions in the United States and the countries in which the Basket Currencies are circulated as legal tender, particularly relative rates of inflation, interest rate levels, the balance of payments and the extent of governmental surpluses or deficits in those countries.

Foreign exchange rates can either be fixed by the sovereign government, allowed to float within a range of exchange rates set by the government, or left to float freely. Governments, including those issuing the Basket Currencies, use a variety of techniques, such as intervention by their central bank or imposition of regulatory controls or taxes, to affect the exchange rates of their respective currencies. They may also issue a new currency to replace an existing currency or alter the exchange rate or relative exchange characteristics by devaluation or revaluation of a currency. Thus, a special risk in purchasing the Notes is that their liquidity, trading value and amount payable could be affected by the actions of sovereign governments that could change or interfere with previously freely determined currency valuations, fluctuations in response to other market forces and the movement of currencies across borders. There will be no offsetting adjustment or change made during the term of the Notes in the event that the exchange rates should become fixed (or in the case of certain currencies, become floating), or in the event of any devaluation or revaluation or imposition of exchange or other regulatory controls or taxes or in the event of other developments affecting a Basket Currency, the U.S. dollar, or any other currency.

In addition, investments in or related to the currencies of emerging markets such as China, India, Indonesia and the Philippines are also subject to greater risks than those in more developed markets, as discussed below. The information below is taken from and based on publicly available information.

The People’s Republic of China. In 2005, the People’s Bank of China, with the authorization of the State Council of the People’s Republic of China, announced that the Chinese renminbi exchange rate would no longer be pegged to the U.S. dollar and would float within managed bands, which are reset daily. After the closing of the market on each business day, the People’s Bank of China announces the closing price of a foreign currency, such as the U.S. dollar, traded against the Chinese renminbi in the interbank foreign exchange market. This closing price then becomes the central point of the managed trading band for that currency for the following business day. Despite the recent change in its exchange rate regime, the Chinese government continues to manage the valuation of the Chinese renminbi, and further changes in the Chinese government’s management of the Chinese renminbi may impact the exchange rate for the Chinese renminbi relative to the U.S. dollar.

The Republic of India. The Indian government has pursued policies of economic liberalization and deregulation, but the government’s role in the economy has remained significant. The Indian government allows the exchange rate to float freely, without a fixed target or band, but may intervene when it deems necessary to preserve stability. It also has the ability to restrict the conversion of rupees into foreign currencies, and, under certain circumstances, investors that seek to convert rupees into foreign currency must obtain the approval of the Reserve Bank of India. If the Indian government prevents the Indian rupee from floating freely in order to preserve stability, or if the Indian government, with the approval of the Reserve Bank of India, restricts the conversion of rupees into foreign currencies, the exchange rate of the Indian rupee relative to the U.S. dollar may be adversely impacted.

Indonesia. From 1977 to 1997, the Indonesian government maintained a managed floating exchange rate system under which the Indonesian rupiah was linked to a basket of currencies. In 1997, the Indonesian rupiah depreciated significantly during the Asian currency crisis and the Indonesian government subsequently abandoned its trading band policy and permitted the Indonesian rupiah to float without an announced level at which the government would intervene. The Indonesian government continues to intervene in the foreign exchange market and to impose restrictions on certain foreign exchange transactions and dealings. Factors that might affect the Indonesian government’s policy with respect to the Indonesian rupiah include the extent of Indonesia’s foreign currency reserves, the balance of payments, the extent of governmental surpluses and deficits, the size of Indonesia’s debt service burden relative to the economy as a whole, regional hostilities, terrorist attacks or social unrest, and political constraints to which Indonesia may be subject.

6

Philippines. The Philippine peso has been a floating currency since the mid-1960s. Between 1996 and 2001, the Philippine peso depreciated significantly during and following the Asian financial crisis, and beginning in 2000, the Philippine Central Bank (the Bangko Sentral) began implementing a series of measures to curb foreign exchange speculation and foreign exchange volatility, including requiring a minimum holding period for foreign investments in peso time deposits and establishing documentary requirements for foreign exchange forward and swap transactions. The current administration has also continued to experience domestic political instability, including terrorist activity and attempted coups. Factors that might affect the Philippine government’s policy with respect to the Philippine peso include the extent of the Philippine’s foreign currency reserves, the balance of payments, the extent of governmental surpluses and deficits, the size of Philippine’s debt service burden relative to the economy as a whole, regional hostilities, terrorist attacks or social unrest, and political constraints to which the Philippines may be subject.

^¨ Volatility of currency markets — The value of the Basket Currencies relative to the U.S. dollar have in the past been, and may continue to be, volatile and may vary based on a number of interrelated factors, including economic, financial and political events that Lehman Brothers Holdings Inc. cannot control.

^¨ Changes in the value of the Basket Currencies may offset each other — The Basket Return will be based on the appreciation or depreciation of the aggregate Basket Currencies as a whole. Movements in the exchange rates of the Basket Currencies may not correlate with each other, and an increase in the values of some but not all of the Basket Currencies relative to the U.S. dollar may be substantially or entirely offset by decreases in the values of the other Basket Currencies relative to the U.S. dollar. As a result, a positive Basket Return, and a resulting Additional Amount greater than zero, cannot be assured by appreciation in only some of the Basket Currencies. Any gain in one position may be offset by a loss in another position.

^¨ Exchange rates for the Basket Currencies prior to the Valuation Date will not factor into the calculation of the Basket Return — Because the Additional Amount will be based on the Basket Return, which in turn is calculated based on the Final Spot Rate for each basket Currency on the Valuation Date, a single day near the end of the term of the Notes, the exchange rates for the Basket Currencies at other times during the term of the Notes or at the Maturity Date may have appreciated more (or depreciated less) than the Final Spot Rates for the Basket Currencies on the Valuation Date.

^¨ Even though currency trades around-the-clock, the Notes may not — The interbank market in foreign currencies is a global, around-the-clock market. The hours of trading for the Notes may not conform to the hours during which the Basket Currencies and the U.S. dollar are traded. Significant price and rate movements may take place in the underlying foreign exchange markets that will not be reflected immediately in the market price of the Notes.

^¨ The market for the Notes may be illiquid — The Notes will not be listed on any securities exchange, and as a result, there may be little or no secondary market for the Notes. Subject to regulatory constraints, Lehman Brothers Inc. has agreed to use reasonable efforts to make a market in the Notes for so long as the Notes are outstanding. Even if there is a secondary market, it may not provide enough liquidity to allow you to sell the Notes easily, and if at any time Lehman Brothers Inc. were to cease acting as market makers, it is likely that there would be no secondary market for the Notes.

^¨ Potential conflicts of interest — Lehman Brothers Inc. and other affiliates of Lehman Brothers Holdings Inc. play a variety of roles in connection with the issuance of the Notes, including acting as Calculation Agent and hedging Lehman Brothers Holdings Inc.’s obligations under the Notes. In performing these duties, the economic interests of the Calculation Agent and other affiliates of Lehman Brothers Holdings Inc. are potentially adverse to your interests as an investor in the Notes.

^¨ Commissions and Hedging Costs — The original issue price of the Notes includes the underwriting commissions and fees and Lehman Brothers Holdings Inc.’s cost of hedging its obligations under the Notes through one or more of its affiliates. Such cost includes such affiliates’ expected cost of providing this hedge, as well as the profit these affiliates expect to realize in consideration for assuming the risks inherent in providing such hedge. As a result, assuming no change in market conditions or any other relevant factors, the price, if any, at which you are able to sell Notes in secondary market transactions, if at all, will likely be lower than the original issue price.

^¨ Suspension or disruption of market trading in the Basket Currencies — Certain events, including events involving the suspension or disruption of market trading in the Basket Currencies, constitute Disruption Events under the terms of the Notes. To the extent any of these events occurs with respect to a Basket Currency and remains in effect on the Valuation Date, the Valuation Date for the affected Basket Currency may be postponed until the Disruption Event ceases to be in effect or, if the Disruption Event remains in effect for three scheduled Valuation Business Days, the exchange rate for the affected Basket Currency will be determined by the Calculation Agent in good faith based on quotations from dealers in the market for the relevant Basket Currency or, in certain circumstances, in the Calculation Agent’s discretion. In the event that the Valuation Date for one or more Basket Currencies is postponed, the Basket Return may be lower, and could result in the Additional Amount being lower, than what you may have anticipated based on the last available exchange rate for any affected Basket Currency as of the scheduled Valuation Date. For further information, see “Disruption Events” above.

^¨ You must rely on your own evaluation of the merits of an investment linked to the Basket Currencies — In the ordinary course of their businesses, Lehman Brothers Holdings Inc., Lehman Brothers Inc., UBS Financial Services Inc. or their respective affiliates may from time to time express views on expected movements in the exchange rates of the Basket Currencies or other currencies. These views are sometimes communicated to clients who participate in the markets for the Basket Currencies and other currencies. However, these views, depending upon worldwide economic, political and other developments, may vary over differing time horizons and are subject to change. In connection with your purchase of the Notes, you should investigate the Basket Currencies and the markets in which they trade and not rely on views which may be expressed by Lehman Brothers Holdings Inc., Lehman Brothers Inc., UBS Financial Services Inc. or their respective affiliates in the ordinary course of their businesses with respect to future Basket Currency or other currency price movements.

^¨ Historical information about the exchange rates for the Basket Currencies may not be indicative of future values — Historical information on the exchange rates of the Basket Currencies relative to the U.S. dollar, and hypothetical historical information concerning the composite Basket performance, furnished herein is provided as a matter of information only, and you should not regard the information as indicative of the range of, or trends in, future fluctuations in the exchange rates for the Basket Currencies relative to the U.S. dollar, the future performance of the Basket, the Basket Return or what the value of the Notes may be. Fluctuations in exchange rates make it difficult to predict whether the Additional Amount will be payable at maturity, or what that

7

Additional Amount, if any, may be. Historical exchange rate fluctuations may be greater or lesser than those experienced by the holders of the Notes.

^¨ Certain activities by Lehman Brothers Holdings Inc., Lehman Brothers Inc, UBS Financial Services Inc. and their respective affiliates may adversely affect the value of the Notes — Lehman Brothers Holdings Inc. or one or more of its affiliates may hedge its obligations under particular notes by purchasing or selling the Basket Currencies, options or futures on the Basket Currencies or other instruments linked to the Basket Currencies, and may adjust the hedge by, among other things, purchasing or selling any of the foregoing, at any time and from time to time, and by unwinding the hedge by selling any of the foregoing. Lehman Brothers Holdings Inc. or one or more of its affiliates also may enter into, adjust and unwind hedging transactions relating to other notes whose returns are linked to the same Basket Currencies. Lehman Brothers Inc., UBS Financial Services Inc. and their respective affiliates may engage in trading in the Basket Currencies, or instruments whose returns are linked to the Basket Currencies, either for their proprietary accounts, for other accounts under their management or to facilitate transactions on behalf of customers. Any of these activities may adversely affect the market values or levels of the Basket Currencies and therefore the market value of the Notes. It is possible that Lehman Brothers Holdings Inc., Lehman Brothers Inc., UBS Financial Services Inc. or their respective affiliates could receive positive returns with respect to these activities while the value of the Notes may decline.

Lehman Brothers Holdings Inc. or its affiliates also have issued and in the future may issue, and Lehman Brothers Inc., UBS Financial Services Inc. and their respective affiliates also have underwritten on behalf of other issuers and in the future may underwrite, other securities or financial or derivative instruments with returns linked to changes in the level of the Basket Currencies or other currencies. By introducing competing products into the marketplace in this manner, Lehman Brothers Holdings Inc., Lehman Brothers Inc., UBS Financial Services Inc. and their respective affiliates could adversely affect the value of the Notes and the amount payable on the Notes.

^¨ The trading value of the Notes may reflect a time premium or discount — As a result of a “time premium or discount,” the Notes may trade at a value above or below that which would be expected based on the level of interest rates and the values of the Basket Currencies relative to the U.S. dollar. A “time premium or discount” results from expectations regarding the value of one or more Basket Currencies relative to the U.S. dollar during the period prior to the Maturity Date. However, as the time remaining to the Maturity Date decreases, this time premium or discount may diminish, thereby decreasing or increasing the market value of the Notes.

^¨ The Notes are not foreign currencies, and holders of the Notes will have no rights to receive the Basket Currencies — The Notes are linked to the composite value of the Basket Currencies relative to the U.S. dollar, but are not themselves the basket Currencies. The Payment at Maturity on the Notes will be made in U.S. dollars, and investing in the Notes will not entitle holders of the notes to receive the Basket Currencies.

Hypothetical Historical Basket Ending Level

The following chart shows the hypothetical Basket Ending Level at the end of each week in the period from the week ending April 27, 1997 through the week ending April 29, 2007, using a Basket Ending Level indexed to 100 on April 29, 2007, based upon Initial Spot Rates determined on that day. The Basket Ending Level for any prior day was obtained by using the formula for the calculation of the Basket Ending Level described above. For purposes of the Notes and the determination of the Additional Amount (if any), the Basket Starting Level will be indexed to 100 on the Trade Date.

The hypothetical historical Basket Ending Level chart above was prepared using historical weekly data for the Basket Currencies obtained from Reuters; none of UBS Financial Services Inc., Lehman Brothers Inc. or Lehman Brothers Holdings Inc. makes any representation or warranty as to the accuracy or completeness of this data. The hypothetical historical Basket Return is not necessarily indicative of the future performance of the Basket, the Basket Return or what the value of the Notes may be. Fluctuations in exchange rates make it difficult to predict whether the Additional Amount will be payable at maturity, or what that Additional Amount, if any, may be. Historical exchange rate fluctuations may be greater or lesser than those experienced by the holders of the Notes.

9

Historical Exchange Rates

The following charts show the spot exchange rates for each Basket Currency at the end of each week in the period from the week ending April 27, 1997 through the week ending April 29, 2007. The spot exchange rates are expressed as the amount of U.S. dollars per Basket Currency to show the appreciation or depreciation, as the case may be, of the Basket Currency against the U.S. dollar. The spot exchange rates used to calculate the Basket Return are expressed as the amount of Basket Currency per U.S. dollar, which are the inverse of the spot exchange rates presented in the following charts.

10

The historical exchange rates presented in the charts above were prepared using historical data obtained from Reuters; none of UBS Financial Services Inc., Lehman Brothers Inc. or Lehman Brothers Holdings Inc. makes any representation or warranty as to the accuracy or completeness of this data. The historical data on each Basket Currency is not necessarily indicative of the future performance of the Basket Currencies, the Basket Return or what the value of the Notes may be. Fluctuations in exchange rates make it difficult to predict whether the Additional Amount will be payable at maturity, or what that Additional Amount, if any, may be. Historical exchange rate fluctuations may be greater or lesser than those experienced by the holders of the Notes.

The following additional payment examples for the Notes shows scenarios for the Payment at Maturity of the Notes, illustrating positive and negative Basket Ending Levels and Basket Returns reflecting either correlated or offsetting appreciation and depreciation in the different Basket Currencies. The following examples are, like the above, based on a hypothetical Participation Rate of 250%, as well as hypothetical Initial Spot Rates for the Basket Currencies (each of which will be determined on the Trade Date) and for the Final Spot Rates (which will be determined on the Valuation Date), and consequently of the Basket Ending Level and Basket Return. The hypothetical Initial Spot Rate and Final Spot Rate values for the Basket Currencies have been chosen arbitrarily for the purpose of these examples, are not associated with Lehman Brothers Research forecasts for any Basket Currency/USD exchange rates and should not be taken as indicative of the future performance of any Basket Currency/USD exchange rate.

Example A: CNY, IDR, INR and PHP each appreciate relative to their Initial Spot Rates, resulting in a Basket Ending Level of 108.52 and a Basket Return of 8.52%, and therefore a Payment at Maturity of $12.13 per $10 Note.

Because the Basket Return is 8.52%, which is greater than zero, the Additional Amount is equal to $2.13, and the Payment at Maturity is equal to $12.13, per $10 Note (a return of 21.3% per $10 Note), calculated as follows:

$10 + ($10 x 8.52% x 250%) = $12.13.

The table below illustrates how the Basket Ending Level in the above example was calculated:

Basket Currency	Initial Spot Rate (on Trade Date)	Final Spot Rate (on Valuation Date)	Currency Return	Basket Currency Weighting	Weighted Currency Return
CNY	7.7169	7.2539	0.0638	25%	0.0160
IDR	9091	8273	0.0989	25%	0.0247
INR	41.59	36.60	0.1364	25%	0.0341
PHP	47.45	45.55	0.0417	25%	0.0104
		Sum of Weighted Currency Returns =			0.0852
Basket Ending Level = 100 x (1 + Sum of Weighted Currency Returns) =					108.52

Example B: CNY, IDR, INR and PHP each depreciate relative to their Initial Spot Rates, resulting in a Basket Ending Level of 95.48 and a Basket Return of –4.52%, and therefore a Payment at Maturity of $10 per $10 Note.

Because the Basket Return is –4.52%, which is less than zero, the Additional Amount is equal to $0, and the Payment at Maturity is equal to $10, per $10 Note (the repayment of principal invested, because the Notes are 100% principal protected, with 0% additional return).

The table below illustrates how the Basket Ending Level in the above example was calculated:

Basket Currency	Initial Spot Rate (on Trade Date)	Final Spot Rate (on Valuation Date)	Currency Return	Basket Currency Weighting	Weighted Currency Return
CNY	7.7169	8.0256	–0.0385	25%	–0.0096
IDR	9091	9364	–0.0291	25%	–0.0073
INR	41.59	43.67	–0.0476	25%	–0.0119
PHP	47.45	50.77	–0.0654	25%	–0.0164
		Sum of Weighted Currency Returns =			–0.0452
Basket Ending Level = 100 x (1 + Sum of Weighted Currency Returns) =					95.48

Example C: CNY and IDR appreciate relative to their Initial Spot Rates while INR and PHP depreciate relative to their Initial Spot Rates, resulting in a Basket Ending Level of 101.96 and a Basket Return of 1.96%, and therefore a Payment at Maturity of $10.49 per $10 Note.

Because the Basket Return is 1.96%, which is greater than zero, the Additional Amount is equal to $0.49, and the Payment at Maturity is equal to $10.49, per $10 Note (a return of 4.9% per $10 Note), calculated as follows:

$10 + ($10 x 1.96% x 250%) = $10.49.

The table below illustrates how the Basket Ending Level in the above example was calculated:

Basket Currency	Initial Spot Rate (on Trade Date)	Final Spot Rate (on Valuation Date)	Currency Return	Basket Currency Weighting	Weighted Currency Return
CNY	7.7169	6.7523	0.1429	25%	0.0357
IDR	9091	8091	0.1236	25%	0.0309
INR	41.59	47.41	–0.1228	25%	–0.0307
PHP	47.45	50.77	–0.0654	25%	–0.0164
		Sum of Weighted Currency Returns =			0.0196
Basket Ending Level = 100 x (1 + Sum of Weighted Currency Returns) =					101.96

Example D: INR and PHP appreciate relative to their Initial Spot Rates while CNY and IDR depreciate relative to their Initial Spot Rates, resulting in a Basket Ending Level of 98.78 and a Basket Return of –1.22%, and therefore a Payment at Maturity of $10 per $10 Note.

Because the Basket Return is –1.22%, which is less than zero, the Additional Amount is equal to $0, and the Payment at Maturity is equal to $10.00, per $10 Note (the repayment of principal invested, because the Notes are 100% principal protected, with 0% additional return).

The table below illustrates how the Basket Ending Level in the above example was calculated:

Basket Currency	Initial Spot Rate (on Trade Date)	Final Spot Rate (on Valuation Date)	Currency Return	Basket Currency Weighting	Weighted Currency Return
CNY	7.7169	8.7973	–0.1228	25%	–0.0307
IDR	9091	10455	–0.1305	25%	–0.0326
INR	41.59	39.93	0.0416	25%	0.0104
PHP	47.45	40.81	0.1627	25%	0.0407
		Sum of Weighted Currency Returns =			–0.0122
Basket Ending Level = 100 x (1 + Sum of Weighted Currency Returns) =					98.78

Supplemental Plan of Distribution

We will agree to sell to UBS Financial Services Inc. and Lehman Brothers Inc., together the “Agents”, and the Agents will agree to purchase, all of the Notes at the price indicated on the cover hereof and on the cover of the pricing supplement, the document that will be filed pursuant to Rule 424(b) containing the final pricing terms of the Notes.

We have agreed to indemnify the Agents against liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments that the Agents may be required to make relating to these liabilities as described in the MTN Prospectus Supplement and the base prospectus.

We expect to deliver the Notes against payment on or about May 31, 2007, which will be the fourth business day following the Trade Date. 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 Trade Date, it will be required, by virtue of the fact that the Notes initially will settle on the fourth business day following the Trade Date, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement.

Subject to regulatory constraints, Lehman Brothers Inc. has agreed to use reasonable efforts to make a market in the Notes for so long as the Notes are outstanding.

We or our affiliate will enter into swap agreements or related hedge transactions with one of our other affiliates or unaffiliated counterparties in connection with the sale of the Notes and the Agents and/or an affiliate may earn additional income as a result of payments pursuant to the swap or related hedge transactions.
