SUMMARY INFORMATION — Q&A

This summary highlights selected information from this pricing supplement, the MTN prospectus supplement and the base prospectus to help you understand the notes. You should carefully read this pricing supplement, the MTN prospectus supplement and the base prospectus to understand fully the terms of the notes and the tax and other considerations that are important to you in making a decision about whether to invest in the notes. You should pay special attention to the “Risk Factors” section on page S-4 of the MTN prospectus supplement to determine whether an investment in the notes is appropriate for you.

What are the notes?

The notes will be a series of our senior debt that are linked to a basket (the “Basket”) that measures the performance of the U.S. dollar (USD), relative to the Euro (EUR), Japanese Yen (JPY), British Pound (GBP), Canadian Dollar (CAD), Swedish Krona (SEK), and Swiss Franc (CHF). We refer to EUR, JPY, GBP, CAD, SEK and CHF as the Reference Currencies. Each of the EUR, JPY, GBP, CAD, SEK and CHF makes up a portion of the Basket, with a Weighting of 57.6%, 13.6%, 11.9%, 9.1%, 4.2% and 3.6%, respectively.

The notes will rank equally with all other unsecured debt of Lehman Brothers Holdings Inc., except subordinated debt, and will mature on March 1, 2010 (or if such day is not a New York business day, the next succeeding New York business day).

What payments will I receive on the notes before maturity?

None. Unlike ordinary debt securities, the notes do not pay interest before maturity.

What will I receive if I hold the notes until the stated maturity date?

We have designed this type of note for investors who want to protect their investment by receiving at least the principal amount of their investment at maturity and who also want to participate in a possible change in the value of the U.S. dollar relative to the Reference Currencies. At maturity, you will receive a payment equal to the sum of:

•the principal amount of the notes; and

•the Additional Amount, if any.

As a result, if you hold the notes until maturity, you will not receive less than the principal amount.

How will the Additional Amount be calculated?

The Additional Amount is a single U.S. dollar amount equal to the principal amount of the notes multiplied by the product of the Leverage times the Basket Return, if the Basket Return is greater than zero; provided that the minimum Additional Amount payable on the notes shall be zero.

The Leverage is 100%.

The Basket Return is the sum of the Weighted Currency Returns. For EUR and GBP, the Weighted Currency Return is the product of the Weighting for each of EUR and GBP times a quotient, the numerator of which is the difference of the Initial Reference Currency Rate for such Reference Currency minus the Settlement Rate for such Reference Currency and the denominator of which is the Settlement Rate for such Reference Currency. For JPY, CAD, SEK and CHF, the Weighted Currency Return is the product of the Weighting for each of JPY, CAD, SEK and CHF times a quotient, the numerator of which is the difference of the Settlement Rate for such Reference Currency minus the Initial Reference Currency Rate for such Reference Currency and the denominator of which is the Initial Reference Currency Rate for such Reference Currency.

The Initial Reference Currency Rate for each Reference Currency is as follows:

Reference Currency	Initial Reference Currency Rate
BRL	1.4883
RUB	107.66
INR	1.9723
CNY	0.9871
KRW	6.2534

The Settlement Rate for each Reference Currency is the Reference Exchange Rate on the Valuation Date, determined by the Calculation Agent in accordance with the applicable Settlement Rate Option (as defined in “Description of the Notes” below), subject to the occurrence of a Disruption Event (as defined in “Description of the Notes” below).

The Valuation Date is February 24, 2010; provided that, upon the occurrence of a Disruption Event with respect to a Reference Currency, the Valuation Date for the affected Reference Currency may be postponed (as described in “Description of the Notes” below).

PS-1

The Reference Exchange Rates are, for EUR and GBP, the spot exchange rates for each of EUR and GBP quoted against the U.S. dollar, expressed as the number of USD per unit of the Reference Currency. The Reference Exchange Rates for JPY, CAD, SEK and CHF are the spot exchange rate for each of JPY, CAD, SEK and CHF, respectively, quoted against the U.S. dollar, expressed as the number of units of the Reference Currency per one USD.

For further information concerning the calculation of the Additional Amount, see “Description of the Notes” below. You can review hypothetical Redemption Amount payment examples under “Description of the Notes—Hypothetical Redemption Amount Payment Examples” below.

How will I be able to find the Basket Return at any point in time?

You can obtain the Basket Return at any time by calling your Lehman Brothers sales representative.

You can review the historical performance of the Reference Currencies under “Historical Exchange Rates” below.

Are there any risks associated with my investment?

Yes, the notes will be subject to a number of risks. See “Risk Factors” beginning on page S-4 of the MTN prospectus supplement.

What about taxes?

We intend to treat the notes as contingent payment debt instruments as described under “Certain United States Federal Income Tax Consequences” below and “Supplemental United States Federal Income Tax Consequences—Contingent Payment Debt Instruments” in the MTN prospectus supplement.

What happens in the event of a Disruption Event?

If the Calculation Agent determines that a Disruption Event (as defined in “Description of the Notes” below) relating to one or more of the Reference Currencies is in effect on the scheduled Valuation Date, the Calculation Agent will determine the Basket Return using:

•for each Reference Currency that did not suffer a Disruption Event on the scheduled Valuation Date, the Settlement Rate on the scheduled Valuation Date, and

•for each Reference Currency that did suffer a Disruption Event on the scheduled Valuation Date, the Settlement Rate on the immediately succeeding scheduled Valuation Business Day for such Reference Currency on which no Disruption Event occurs or is continuing with respect to such Reference Currency;

provided however that if a Disruption Event has occurred or is continuing with respect to a Reference 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 Reference Currency; and (b) the Calculation Agent will determine the Settlement Rate for the affected Reference Currency on such day in accordance with the Fallback Rate Observation Methodology, as defined under “Description of the Notes—Currency-Indexed Notes” in the MTN prospectus supplement.

Who is Lehman Brothers Holdings?

Lehman Brothers Holdings Inc. and its subsidiaries (collectively “Lehman Brothers Holdings”) an innovator in global finance, serves the financial needs of corporations, governments and municipalities, institutional clients and high-net-worth clients worldwide. Lehman Brothers Holdings’ worldwide headquarters in New York and regional headquarters in London and Tokyo are complemented by offices in additional locations in North America, Europe, the Middle East, Latin America and the Asia Pacific region. See “Prospectus Summary – Lehman Brothers Holdings Inc.” and “Where You Can Find More Information” on pages 1 and 58, respectively, of the base prospectus.

You may request a copy of any document Lehman Brothers Holdings files with the Securities and Exchange Commission, or the SEC, pursuant to the Securities and Exchange Act of 1934, at no cost, by writing or telephoning Lehman Brothers Holdings at the address set forth under the caption “Where You Can Find More Information” in the base prospectus.

What is the role of Lehman Brothers Inc.?

Lehman Brothers Inc., one of our subsidiaries, will be the agent and the calculation agent for purposes of determining whether the Additional Amount is payable on the Maturity Date as well as determining whether a Disruption Event has occurred. Potential conflicts of interest may exist between Lehman Brothers Inc. and you as a beneficial owner of the notes. See “Risk Factors—An affiliate of ours may act as calculation agent on the notes, creating a potential conflict of interest between you and us” in the MTN prospectus supplement and “Description of the Notes” below.

PS-2

Can you tell me more about the effect of hedging activity by Lehman Brothers Holdings?

We expect to hedge our obligations under the notes through one or more of our affiliates. This hedging activity will likely involve trading in the Reference Currencies or in other instruments, such as options, swaps or futures, based on the Reference Currencies. This hedging activity could adversely affect the price at which your notes will trade in the secondary market. Moreover, this hedging activity may result in us or our affiliates receiving a profit, even if the market value of the notes declines.

In what form will the notes be issued?

The notes of each series will be represented by one or more global securities that will be deposited with and registered in the name of The Depository Trust Company or its nominee. Except in very limited circumstances you will not receive a certificate for your notes.

Will the notes be listed on a stock exchange?

No, the notes will not be listed on a stock exchange.

After the initial offering of the notes, Lehman Brothers Inc. intends to make a market in the notes and may stabilize or maintain the market price of the notes during the initial distribution of the notes. However, Lehman Brothers Inc. will not be obligated to engage in any of these market activities or to continue them once they are begun. No assurance can be given as to the liquidity of the trading market for the notes.

PS-3

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” generally, and “Risk Factors—Risks Relating to Currency-Indexed Notes” specifically, in the MTN prospectus supplement.

DESCRIPTION OF THE NOTES

The U.S.$870,000 aggregate principal amount of FX Basket-Linked Notes Due March 1, 2010 offered hereby are Medium-Term Notes, Series I, of Lehman Brothers Holdings Inc.  The CUSIP number for the notes is 5252M0DM6 and the ISIN number is US5252M0DM60. The notes will be issued in book-entry form only, and will be eligible for transfer through the facilities of DTC or any successor depository. See “Book-Entry Procedures and Settlement” in the base prospectus.

The notes will be issued in minimum denominations of U.S.$1,000 and in integral multiples of U.S.$1,000 in excess thereof, and will have a stated “Maturity Date” of March 1, 2010 or if such day is not a New York business day, the next succeeding New York business day.

The notes allow you to hold a long position in the U.S. dollar relative to a single basket of currencies, inlcuding the Euro (EUR), Japanese Yen (JPY), British Pound (GBP), Canadian Dollar (CAD), Swedish Krona (SEK), and Swiss Franc (CHF). Each of the EUR, JPY, GBP, CAD, SEK and CHF (each a “Reference Currency” and, collectively, the “Reference Currencies”) makes up a portion of the “Basket” with a weighting, on the date of this pricing supplement, of 57.6%, 13.6%, 11.9%, 9.1%, 4.2% and 3.6%, respectively.

If held to the Maturity Date, holders of the notes will receive on the Maturity Date a single payment in U.S. dollars in an amount equal to the Redemption Amount as described below. No interest will accrue during the term of the notes and no interest will be payable on the Maturity Date except in the event that the Redemption Amount is not paid when due, as described below.

The “Reference Exchange Rates” are, for EUR and GBP, the spot exchange rates for each of EUR and GBP quoted against the U.S. dollar, expressed as the number of USD per unit of the Reference Currency. The Reference Exchange Rates for JPY, CAD, SEK and CHF are the spot exchange rate for each of JPY, CAD, SEK and CHF, respectively, quoted against the U.S. dollar, expressed as the number of units of the Reference Currency per one USD.

The “Settlement Rate” for each Reference Currency is the Reference Exchange Rate on the Valuation Date, determined by the Calculation Agent in accordance with the applicable Settlement Rate Option (subject to the occurrence of a Disruption Event).

The “Leverage” is 100%.

The “Redemption Amount” for each note will be an amount equal to the sum of the principal amount of each note plus the Additional Amount, if any.  The Additional Amount is linked to the Basket Return, which in turn is based on whether the USD has appreciated or depreciated, in aggregate, relative to the Reference Currencies on the Valuation Date. Holders of the notes will receive on the Maturity Date an amount equal to not less than the principal amount of each note.

The “Additional Amount” is a single U.S. dollar amount equal to the principal amount of the notes multiplied by the product of the Leverage times the Basket Return, if the Basket Return is greater than zero; provided that the minimum Additional Amount payable on the notes shall be zero.

The “Basket Return” is the sum of the Weighted Currency Returns for each Reference Currency.  The “Weighted Currency Return” for EUR and GBP is the product of the Weighting for each of EUR and GBP times a quotient, the numerator of which is the difference of the Initial Reference Currency Rate for such Reference Currency minus the Settlement Rate for such Reference Currency and the denominator of which is the Settlement Rate for such Reference Currency.  The Weighted Currency Return for JPY, CAD, SEK and CHF is the product of the Weighting for each of JPY, CAD, SEK and CHF times a quotient, the numerator of which is the difference of the Settlement Rate for such Reference Currency minus the Initial Reference Currency Rate for such Reference Currency and the denominator of which is the Initial Reference Currency Rate for such Reference Currency.

The “Initial Reference Currency Rate” for each Reference Currency is the Reference Exchange Rate for that Reference Currency on the Trade Date,

PS-4

determined in accordance with the applicable Settlement Rate Option, as follows:

Reference Currency	Weighting	Initial Reference Currency Rate
EUR	57.6%	1.4883
JPY	13.6%	107.66
GBP	11.9%	1.9723
CAD	9.1%	0.9871
SEK	4.2%	6.2534
CHF	3.6%	1.0848

The “Valuation Date” is February 24, 2010; provided that, upon the occurrence of a Disruption Event with respect to a Reference Currency, the Valuation Date for the affected Reference Currency may be postponed (as described below).

The “Trade Date” is the date hereof.

The “Issue Date” is February 29, 2008.

The “Settlement Rate Option” and “Valuation Business Day” for each Reference Currency are as follows:

Reference Currency	Screen Reference*	Valuation Business Day
EUR	Reuters page EURUSDFIXM=WM (as substitute for 1FED)	London
JPY	Reuters page USDJPYFIXM=WM (as substitute for 1FED)	London
GBP	Reuters page GBPUSDFIXM=WM (as substitute for 1FED)	London
CAD	Reuters page USDCADFIXM=WM (as substitute for 1FED)	London
SEK	Reuters page USDSEKFIXM=WM (as substitute for 1FED)	London
CHF	Reuters page USDCHFFIXM=WM (as substitute for 1FED)	London

*              In each case, as observed at approximately 4:00 p.m. London time.

For further information concerning the Settlement Rate Option and Valuation Business Day, see “Description of the Notes—Currency-Indexed Notes” in, and Appendix A to, the MTN prospectus supplement.

If a Disruption Event relating to one or more of the Reference Currencies is in effect on the scheduled Valuation Date, the Calculation Agent will determine the Basket Return using:

•for each Reference Currency that didnot suffer a Disruption Event on the scheduled Valuation Date, the Settlement Rate on the scheduled Valuation Date, and

•for each Reference Currency that did suffer a Disruption Event on the scheduled Valuation Date, the Settlement Rate on the immediately succeeding scheduled Valuation Business Day for such Reference Currency on which no Disruption Event occurs or is continuing with respect to such Reference Currency;

provided however that if a Disruption Event has occurred or is continuing with respect to a Reference 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 Reference Currency; and (b) the Calculation Agent will determine the Settlement Rate for the affected Reference Currency on such day in accordance with the 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 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 (x) the conversion of the Reference Currency into USD through customary legal channels; or (y) for any Reference Currency other than EUR, the delivery of USD from accounts inside the Reference Currency Jurisdiction with respect to such Reference Currency to accounts outside that Reference Currency Jurisdiction;

(B)the occurrence of any event causing the Reference Exchange Rate for the Reference Currency to be split into dual or multiple currency exchange rates; or

(C)the Settlement Rate being unavailable for the Reference Currency, or the occurrence of an event (i) for any Reference Currency other than EUR, in the Reference Currency Jurisdiction for that Reference Currency that materially disrupts the market for the Reference Currency or (ii) that generally makes it impossible to obtain the Settlement Rate for the Reference Currency, on the Valuation Date.

For purposes of the above, “scheduled Valuation Business Day” means a day that is or, in the

PS-5

judgment of the Calculation Agent, should have been, a Valuation Business Day for the affected Reference Currency.

The notes are not subject to redemption at our option or to repayment at the option of the Holders of the notes prior to the Maturity Date.

In case an event of default (as described in the base prospectus) with respect to any note shall have occurred and be continuing, the amount that may be declared due and payable upon any acceleration of the notes will be determined by the Calculation Agent for the period from and including the Issue Date to but excluding the date of early repayment and will equal, for each note, the Redemption Amount, calculated as though the date of early repayment were the Maturity Date. If a bankruptcy proceeding is commenced in respect of Lehman Brothers Holdings, the claim of the beneficial owner of a note for the period from and including the Issue Date to but excluding the date of early repayment will be capped at the Redemption Amount, calculated as though the date of the commencement of the proceeding were the Maturity Date.

Any overdue payment in respect of any note will bear interest until the date upon which all sums due in respect of such note are received by or on behalf of the relevant Holder, at the rate per annum that is the rate for deposits in U.S. dollars for a period of six months that appears on the Reuters Screen LIBOR page as of 11:00 a.m. (London time) on the first London business day following such failure to pay. Such rate will be determined by the Calculation Agent.  If interest in respect of overdue amounts is calculated for a period of less than one year, it will be calculated on the basis of a 360-day year consisting of 12 months of 30 days each, and, in the case of an incomplete month, the number of days elapsed.

The “Calculation Agent” means Lehman Brothers Inc.

PS-6

HISTORICAL EXCHANGE RATES

General

The notes allow you to hold a long position in the U.S. dollar relative to the Basket.

Historical Data on the Reference Currencies

The following charts show the spot exchange rates for each Reference Currency at the end of each week in the period from the week ending February 27, 2005, through the week ending February 24, 2008, using historical data obtained from Reuters; neither Lehman Brothers Inc. nor Lehman Brothers Holdings Inc. makes any representation or warranty as to the accuracy or completeness of this data. The spot exchange rates are expressed as the amount of Reference Currency per U.S. dollar to show the appreciation or depreciation, as the case may be, of the U.S. dollar relative to the Reference Currency (and, in the case of EUR and GBP, are the inverse of the spot exchange rates used to calculate the Basket Return, which are expressed as the amount of U.S. dollars per Reference Currency). The historical data on each Reference Currency is not necessarily indicative of the future performance of the Reference Currencies, the Basket Return or what the value of the notes may be. Fluctuations in exchange rates make it difficult to predict whether the Basket Return will be greater than, less than or equal to zero and, consequently, the Additional Amount payable at maturity. Historical exchange rate fluctuations may be greater or lesser than those experienced by the holders of the notes.

Hypothetical Historical Basket Return

The following chart shows the hypothetical Basket Return at the end of each week in the period from the week ending February 27, 2005, through the week ending February 24, 2008, based on the hypothetical composite performance of the Reference Currencies using data obtained from Reuters; neither Lehman Brothers Inc. nor Lehman Brothers Holdings Inc. makes any representation or warranty as to the accuracy or completeness of this data. The Basket Return was indexed to a level of 0.0 on February 24, 2008, based upon the Reference Exchange Rates determined on that day. The composite value of the Reference Currencies on any prior day was obtained by using the calculation of the Basket Return described above. Spot exchange rates used in this determination are expressed as the number of units of Reference Currency per U.S. dollar (except for EUR and GBP, which are expressed as the number of USD per unit of the Reference Currency). For purposes of the notes and the determination of the Additional Amount, the Basket Return was indexed to 0.0 on the Trade Date.

PS-11

Hypothetical Redemption Amount Payment Examples

The following payment examples for this note show scenarios for the Redemption Amount payable at maturity of the notes, including scenarios for the Additional Amounts payable if the Basket Return is greater or less than zero, based on values for the Leverage (100%) and the Initial Reference Currency Rates (each of which was determined on the Trade Date), as well hypothetical values for the Settlement Rates (which will be determined on the Valuation Date), and the resulting Basket Return.

The Settlement Rate values for the Reference Currencies have been chosen arbitrarily for the purpose of these examples, are not associated with Lehman Brothers Research forecasts for any Reference Currency/USD exchange rates and should not be taken as indicative of the future performance of any Reference Currency/USD exchange rate.

Example 1: The USD appreciates relative to each of the EUR, JPY, GBP, CAD, SEK and CHF, resulting in a Basket Return of 0.0807 (8.07%). Because the Basket Return is greater than zero, the Additional Amount is equal to 8.07%, and the Redemption Amount is equal to 108.07%, times the principal amount of the notes.

Because the Basket Return is 0.0807, the Redemption Amount payable at maturity is equal to $1,080.70 per $1,000 note (reflecting an Additional Amount of $80.70 per note), calculated as follows:

Redemption Amount = $1,000 + ($1,000 * 100% * 0.0807) = $1,080.70

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

Basket Currency	Initial Reference Currency Rate (on Trade Date)	Settlement Rate (on Valuation Date)	Weighting	Weighted Currency Return
EUR	1.4883	1.3692	57.6%	0.0501
JPY	107.66	117.35	13.6%	0.0122
GBP	1.9723	1.8271	11.9%	0.0095
CAD	0.9871	1.0463	9.1%	0.0055
SEK	6.2534	6.6598	4.2%	0.0027
CHF	1.0848	1.1065	3.6%	0.0007
	Basket Return = Sum of Weighted Currency Returns =			0.0807

PS-12

Example 2: The USD depreciates relative to each of the EUR, JPY, GBP, CAD, SEK and CHF, resulting in a Basket Return of –0.0391 (–3.91%). Because the Basket Return is less than zero, the Additional Amount is equal to 0%, and the Redemption Amount is equal to 100%, times the principal amount of the notes.

Because the Basket Return is –0.0391, the Redemption Amount payable at maturity is equal to $1,000 per $1,000 note (reflecting an Additional Amount of $0 per note), the repayment of principal invested, with no additional return.

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

Basket Currency	Initial Reference Currency Rate (on Trade Date)	Settlement Rate (on Valuation Date)	Weighting	Weighted Currency Return
EUR	1.4883	1.5377	57.6%	–0.0185
JPY	107.66	103.35	13.6%	–0.0054
GBP	1.9723	2.0768	11.9%	–0.0060
CAD	0.9871	0.9278	9.1%	–0.0055
SEK	6.2534	6.1283	4.2%	–0.0008
CHF	1.0848	0.9980	3.6%	–0.0029
	Basket Return = Sum of Weighted Currency Returns =			–0.0391

Example 3: The USD appreciates relative to each of the EUR, GBP and CHF, but depreciates relative to the JPY, CAD and SEK, resulting in a Basket Return of 0.0429 (4.29%). Because the Basket Return is greater than zero, the Additional Amount is equal to 4.29%, and the Redemption Amount is equal to 104.29%, times the principal amount of the notes.

Because the Basket Return is 0.0429, the Redemption Amount payable at maturity is equal to $1,042.90 per $1,000 note (reflecting an Additional Amount of $42.90 per note), calculated as follows:

Redemption Amount = $1,000 + ($1,000 * 100% * 0.0429) = $1,042.90

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

Basket Currency	Initial Reference Currency Rate (on Trade Date)	Settlement Rate (on Valuation Date)	Weighting	Weighted Currency Return
EUR	1.4883	1.3525	57.6%	0.0578
JPY	107.66	101.20	13.6%	–0.0082
GBP	1.9723	1.9131	11.9%	0.0037
CAD	0.9871	0.8883	9.1%	–0.0091
SEK	6.2534	5.6280	4.2%	–0.0042
CHF	1.0848	1.1716	3.6%	0.0029
	Basket Return = Sum of Weighted Currency Returns =			0.0429

Example 4: The USD appreciates relative to each of the JPY, GBP and CAD, but depreciates relative to the EUR, SEK and CHF resulting in a Basket Return of –0.0198 (–1.98%). Because the Basket Return is less than zero, the Additional Amount is equal to 0%, and the Redemption Amount is equal to the product of 100%, times the principal amount of the notes.

Because the Basket Return is –0.0198, the Redemption Amount payable at maturity is equal to $1,000 per $1,000 note (reflecting an Additional Amount of $0 per note), the repayment of principal invested, with no additional return.

JPY	107.66	109.81	13.6%	0.0027
GBP	1.9723	1.7928	11.9%	0.0119
CAD	0.9871	1.0068	9.1%	0.0018
SEK	6.2534	5.6280	4.2%	–0.0042
CHF	1.0848	0.9546	3.6%	–0.0043
	Basket Return = Sum of Weighted Currency Returns =			–0.0198

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 MTN prospectus supplement.

PS-15

SUPPLEMENTAL PLAN OF DISTRIBUTION

We have agreed to sell to Lehman Brothers Inc. (the “Agent”), and the Agent has agreed to purchase from us, 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 initially at a public offering price equal to the public offering price on the cover of this pricing supplement and to certain dealers at a discount not to exceed 1.00%. After the initial public offering, the public offering price and the selling terms may from time to time be varied by the Agent.

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.
