Risk Factors

An investment in the notes is subject to risks associated with the performance of the Components Commodities.

The return on the notes at maturity is dependent on the Basket Return, which in turn depends on the performance of the prices of the Component Commodities (Copper and Zinc).  Because the notes do not bear interest, if the Basket Return is equal to or less than 0.0% on the Valuation Date, you will receive at maturity only the principal you invested.

The prices of the Component Commodities are primarily affected by the global demand for and supply of the Component Commodities (including certain specific factors discussed below), but from time to time may also be significantly affected by speculative actions or currency exchange rates.  Demand for the Component Commodities is significantly linked to the level of global industrial economic activity, but is also influenced by other factors such as government regulations (including environmental or consumption policies) and growth in industrial production and gross domestic product in emerging market countries, such as India or China, that have become oversized users of commodities and therefore increased the extent to which commodities rely on these markets.  In addition to general economic activity and demand, prices for a Component Commodity can be influenced by political events, labor activity and supply disruptions in regions of the world that are major producers of the relevant Component Commodity, and which will tend to affect prices of a Component Commodity worldwide, regardless of the location of the event.  It is impossible to predict what effect these factors will have on the value of any Component Commodity and thus, the return on the notes.

In the event of sudden disruptions in the supplies of a Component Commodity, such as those caused by war, natural events, or accidents, prices of the Component Commodity and futures contracts on the Component Commodity could become extremely volatile and unpredictable. Also, sudden and dramatic changes in the futures market may occur, for example, upon the introduction of new or previously withheld supplies of the Component Commodity into the market or the introduction of substitute products or commodities.  In addition, there are substitutes for each of the Component Commodities in various applications, and the availability and price of these substitutes (and in particular, a decrease in the price of any of these substitute commodities) will also affect demand for a Component Commodity and may have a material adverse effect on the price of a Component Commodity.

Specific factors affecting the price of Copper.  The price of copper is primarily affected by the global demand for and supply of copper. Copper is a conductor of electricity, and one of the most significant applications for copper is the production of cable, wire and electrical products for both the electrical and building industries. Construction is another principal industrial application for copper, which is used in pipes for plumbing, heating, ventilation, and air conditioning, along with masonry wiring and sheet metal facing.   Demand for copper products in recent years has been supported by strong consumption from newly industrializing countries due to their copper-intensive economic growth and infrastructure development.  Apart from the United States, Canada and Australia, the majority of copper concentrate supply (the raw material) comes from outside the Organization for Economic Cooperation and Development countries. In previous years, copper supply has been affected by strikes, financial problems and terrorist activity.

Specific factors affecting the price of Zinc.  The price of zinc is primarily affected by the global demand for and supply of zinc.  The manufacture of galvanized steel, which adds protection against corrosion to steel-based building structures, vehicles, machinery and general household equipment, accounts  for a significant percentage of world-wide zinc demand.  Accordingly, the demand for zinc is highly correlated to the supply of and demand for galvanized steel, which is in turn heavily dependent on the automobile and construction sectors.   The largest reserves of zinc concentrate (the raw material) are in Australia, Canada, China and Latin American countries (particularly Peru).

Many factors affect the market 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.

The market value of the notes will be affected by factors that interrelate in complex ways. The effect of one factor may offset the increase in the market value of the notes caused by another factor and the effect of one factor may exacerbate the decrease in the market value of the notes caused by another factor.  For example, the market value of the notes will be affected by changes in the level of interest rates, the time to maturity of the notes (and any associated “time premium”) and the credit ratings of Lehman Brothers Holdings Inc.  In addition, the market value of the notes will also be affected by certain specific factors, which are described in the following paragraphs (along with the expected impact on the market value of the notes given a change in that specific factor, assuming all other conditions remain constant).

The prices of the Component Commodities will affect the market value of the notes. It is expected that the market value of the notes will depend on where the prices of the Component Commodities are trading relative to the Commodity Strikes.

The forward prices of the Component Commodities are currently lower than spot prices, which implies a decline in spot prices over time.  Your return on the notes depends on the Basket Return being greater than 0.0% on the Valuation Date, which in turn depends on the prices for the Component Commodities having appreciated relative to their prices on the Trade Date.  However, the prices for the Component Commodities are currently in “backwardation”, meaning that the forward prices are currently lower than the spot prices, and which implies that the prices of the Component Commodities are expected to decrease in the future.  If the prices of the Component Commodities on the Valuation Date decline in the aggregate during the term of the notes, the Basket Return will be less than 0.0%, and you will receive only the principal amount you invested in the notes at maturity, or $1,000 per each $1,000 principal amount note.

Changes in the volatility of the Component Commodities and their prices are expected to affect the market value of the notes. Volatility is the term used to describe the size and frequency of price and/or market fluctuations. If the volatility of one or more of the Component Commodities or the prices of the Component Commodities increases or decreases, the market value of the notes may be adversely affected. The volatility of the Component Commodities and their prices are affected by a variety of factors, including weather, governmental programs and policies, national and international political and economic events (including terrorist attacks and wars), changes in interest and exchange rates and trading activity in the Component Commodities and futures contracts on the Component Commodities.

Suspension or disruptions of market trading in the commodity markets may adversely affect the value of the notes. The commodity markets are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators and government regulation and intervention. These circumstances could adversely affect the prices of one or more of the Component Commodities and, therefore, the value of your notes.

Active trading in Component Commodity options, futures contracts, options on futures contracts and underlying commodities may adversely affect the value of the notes.  Lehman Brothers Commodity Services Inc. and certain other affiliates of Lehman Brothers Holdings Inc., actively trade the Component Commodities and futures contracts on the Component Commodities on a spot and forward basis and other contracts and products in or related to the Component Commodities and other derivative products (including futures contracts, options on futures contracts and options and swaps on the underlying Component Commodities).  Lehman Brothers Holdings Inc., Lehman Brothers Inc. or their affiliates may also issue or underwrite other financial instruments with returns indexed to one or more of the Component Commodities or futures contracts on the Component Commodities and derivative commodities. These trading and underwriting activities by Lehman Brothers Holdings Inc., Lehman Brothers Inc., Lehman Brothers Commodity Services Inc. or their affiliates, or by unaffiliated third parties, could adversely affect the prices of the Component Commodities, which could in turn affect the return on and the value of the notes.

The inclusion in the original issue price of the broker’s fee and Lehman Brothers Holdings Inc.’s cost of hedging its obligations under the notes through one or more of its affiliates is likely to adversely affect the value of the notes prior to maturity.

The original issue price of the notes includes the broker’s fee 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 a broker will be willing to purchase notes from you in secondary market transactions, if at all, will likely be lower than the original issue price.  In addition, any such prices may differ from values determined by pricing models used by a broker, as a result of such compensation or other transaction costs.

5

The use of a return on a basket of Component Commodities instead of a single Component Commodity return may adversely affect the return on your investment.

The Redemption Amount payable on the notes is based on the Basket Return, which in turn is based on the combined performance of the Component Commodities.  Because price movements in the Component Commodities may not correlate with each other, at a time when the price of one or more of the Component Commodities increases, the price of one or more of the other Component Commodities may increase to a lesser extent or may decline. Therefore, in calculating the Basket Return, increases in the value of one or more of the Component Commodities may be moderated, or wholly offset, by lesser increases or declines in the value of one or more of the other Component Commodities.

The notes are subject to risks associated with a lack of diversification.

Because the notes are linked to the Component Commodities, it will be less diversified than other notes linked to a broader range of products, and therefore could experience greater volatility.  Additionally, the Component Commodities are concentrated in the base metals sector only.  Therefore, an investment in the notes may carry risks similar to a concentrated securities investment in a limited number of industries or sectors.

The return on your notes may not reflect all developments in the Component Commodities.

Because the Redemption Amount will be based on the Basket Return, which in turn is calculated based on the Final Commodity Price for each Component Commodity on the Valuation Date, which is a single Exchange Business Day near the end of the term of the notes, the prices of the Component Commodities at other times during the term of the notes or at the Maturity Date could be higher than the Final Commodity Prices for the Component Commodities on the Valuation Date.  This difference could be particularly large if there is a significant decrease in the prices of the Component Commodities during the latter portion of the term of the notes or if there is significant volatility in the prices of the Component Commodities during the term of the notes, especially on dates near the Valuation Date.

Lack of regulation.

The notes are debt securities that are direct obligations of Lehman Brothers Holdings Inc. The net proceeds to be received by Lehman Brothers Holdings Inc. from the sale of the notes will not be used to purchase or sell futures contracts on the Component Commodities on the Relevant Exchange for the benefit of holders of the notes. The notes are not themselves futures contracts on the Component Commodities, and an investment in the notes does not constitute either an investment in the Component Commodities, futures contracts on the Component Commodities or in a collective investment vehicle that trades in the Component Commodities or futures contracts on the Component Commodities.

Unlike an investment in the notes, an investment in a collective investment vehicle that invests in commodities on behalf of its participants may be regulated as a commodity pool and its operator may be required to be registered with and regulated by the Commodity Futures Trading Commission (“CFTC”) as a “commodity pool operator” (“CPO”). Because the notes are not interests in a commodity pool, the notes will not be regulated by the CFTC as a commodity pool, Lehman Brothers Holdings Inc. will not be registered with the CFTC as a CPO, and you will not benefit from the CFTC’s or any non-U.S. regulatory authority’s regulatory protections afforded to persons who trade in commodities or who invest in regulated commodity pools.

The notes do not constitute investments by you in futures contracts traded on regulated futures exchanges.  Accordingly, you will not benefit from the CFTC’s or any other regulatory authority’s regulatory protections afforded to persons who trade in futures contracts on a regulated futures exchange.

You must rely on your own evaluation of the merits of an investment linked to the Component Commodities.

In the ordinary course of their businesses, affiliates of Lehman Brothers Holdings Inc. may from time to time express views on expected movements in the price of Copper, Zinc and other base metals. These views are sometimes communicated to clients who participate in the markets for the Component Commodities and other base metals. However, these views, depending upon worldwide economic, political and other developments, may vary over differing time horizons and are subject to change. Moreover, other professionals who deal in the markets for the Component Commodities and other base metals may at any time have significantly different views from those of Lehman Brothers Holdings Inc. or its affiliates.  In connection with your purchase of the notes, you should investigate the Component Commodities and other base metal markets and not rely on views which may be expressed by Lehman Brothers Holdings Inc. or its affiliates in the ordinary course of their businesses with respect to future Component Commodity or other base metal price movements.

6

You should make such investigation as you deem appropriate as to the merits of an investment linked to the Component Commodities. Neither the offering of the notes nor any views which may from time to time be expressed by Lehman Brothers Holdings Inc. or its affiliates in the ordinary course of their businesses with respect to future price movements of the Component Commodities or other base metals constitutes a recommendation as to the merits of an investment in your notes.

Suspension or disruption of market trading in the Component Commodities or futures contracts on the Component Commodities and certain other events may require a postponement in the Valuation Date for one or more of the Component Commodities, and may adversely affect the value of the notes.

Certain events, including events involving the suspension or disruption of market trading in Copper or Zinc or Copper or Zinc futures contracts, constitute Disruption Events under the terms of the notes.  For further information on these events, see “Disruption Events” above.  To the extent any of these events occurs with respect to a Component Commodity and remains in effect on the scheduled Valuation Date for the notes, the Valuation Date for the affected Component Commodity may be postponed until the Disruption Event ceases to be in effect or, if the Disruption Event remains in effect for three scheduled Exchange Business Days after the Valuation Date, the price for the affected Component Commodity used to calculate the Basket Return will be determined by the Calculation Agent in its sole and absolute discretion taking into account the latest available quotation for the Commodity Price for the affected Component Commodity and any other information that in good faith it deems relevant.  In the event the Valuation Date for one or more Component Commodities is delayed, the Basket Return may be lower, and could result in the Redemption Amount being lower (and potentially resulting in a greater loss of principal), than what you may have anticipated based on the last available price for any affected Component Commodity as of the scheduled Valuation Date.

There are specific risks you should consider relating to the trading of commodities on the London Metal Exchange.

The Final Commodity Price of Copper and Zinc will be determined by reference to the official cash delivery settlement price of contracts traded on the London Metal Exchange (the “LME”). The LME is a principals’ market which operates in a manner more closely analogous to the over-the-counter physical commodity markets than regulated futures markets, and certain features of regulated futures markets are not present in the context of LME trading. For example, there are no daily price limits on the LME, which would otherwise restrict the extent of daily fluctuations in the prices of LME contracts. In a declining market, therefore, it is possible that prices would continue to decline without limitation within a trading day or over a period of trading days. In addition, a contract may be entered into on the LME calling for delivery on any day from one day to three months following the date of such contract, weekly from three months to six months, and monthly thereafter up to 63, 27 and 15 months forward (depending on the commodity, 63 months forward for Copper and 27 months for Zinc), in contrast to trading on futures exchanges, which call for delivery in stated delivery months. As a result, there may be a greater risk of a concentration of positions in LME contracts on particular delivery dates, which in turn could cause temporary aberrations in the prices of LME contracts for certain delivery dates. If such aberrations are occurring on the Valuation Date, the Basket Return and, therefore, the Redemption Amount, could be adversely affected.

United States Federal Income Tax Treatment

Lehman Brothers Holdings Inc. intends to treat the notes as contingent payment debt instruments, as described under “Supplemental United States Federal Income Tax Consequences—Contingent Payment Debt Instruments” in the prospectus supplement dated May 30, 2006 for the Issuer’s Medium Term Notes, Series I.

Information on the Component Commodities

The Redemption Amount payable on the Maturity Date will be determined by the Basket Return, which is dependent on the official settlement price on the Valuation Date of Copper and Zinc for cash delivery, expressed as the U.S. dollar price per metric ton of Copper and Zinc, as made public by the LME.  Lehman Brothers Holdings Inc. has derived all information regarding the commodities futures markets, the LME and the trading of Copper and Zinc on the LME from publicly available sources.  Information concerning the LME and Copper and Zinc trading on the LME reflects the policies of, and is subject to change without notice by, the LME.  Neither Lehman Brothers Holdings Inc. nor Lehman Brothers Inc. makes any representation or warranty as to the accuracy or completeness of such information.

The daily Commodity Price for each Component Commodity is published on (a) for Copper, Bloomberg page “LOCADY Commodity <Go>” and (b) for Zinc, Bloomberg page “LOZSDY Commodity <Go>”. Each daily Commodity Price is also displayed on Reuters page MTLE.

The Commodity Futures Markets

An exchange-traded futures contract is a bi-lateral contract that provides for the future purchase and sale of a specified type and quantity of a commodity for a fixed price. The contract provides for a specified settlement month in which the commodity is to be delivered by the seller. Rather than settlement by physical delivery of the commodity, futures contracts may be settled for the cash value of the right to receive or sell the specified commodity on the specified date.

Futures contracts are traded on organized exchanges, known as “contract markets”, through the facilities of a centralized clearing house and a brokerage firm which is a member of the clearing house.  The clearing house guarantees the performance of each clearing member which is a party to a futures contract by, in effect, taking the opposite side of the transaction.  U.S. futures markets, as well as brokers and market participants, are subject to regulation by the CFTC.  Futures markets outside the United States are generally subject to regulation by comparable regulatory authorities (such as the Financial Services Authority (FSA) in the United Kingdom).  Because the notes do not constitute futures contracts or commodity options, noteholders will not benefit from the aforementioned clearing house guarantees or the regulatory protections of the CFTC, the FSA or any other non-U.S. regulatory authority.

Information on Copper and Zinc Trading on the LME

According to publicly available information, the LME was established in 1877 and is the principal metal exchange in the world on which contracts for delivery of copper and zinc — as well as nickel, lead, tin, aluminum and aluminum alloy — are traded. In contrast to U.S. futures exchanges, the LME operates as a principals’ market for the trading of forward contracts, and is therefore more closely analogous to over-the-counter physical commodity markets than futures markets. As a result, members of the LME trade with each other as principals and not as agents for customers, although such members may enter into offsetting “back-to-back” contracts with their customers.  Further, the LME does not require client orders to be exposed to the market via LME Select, inter-office dealing or the floor of the exchange trading, and LME members may, at their option (unless they have specific client instructions to the contrary) cross the order against their own book or that of another customer, rather than expose it to the market.  As a result price discovery will take place against LME members’ net exposures during the relevant LME second ring (as discussed below).

In addition, while futures exchanges permit trading to be conducted in contracts for monthly delivery in stated delivery months, LME contracts are be established for delivery on any day (referred to as a “prompt date”) from one day to three months following the date of contract, weekly from three months to six months, and monthly thereafter up to 63, 27 and 15 months forward (depending on the commodity).  Further, there are no price limits applicable to LME contracts, and prices could decline without limitation over a period of time. Trading is conducted on the basis of warrants that cover physical material held in listed warehouses.

The trading on the LME is transacted through open-outcry sessions on the LME floor, electronically on LME Select (the LME’s official electronic trading platform) and through inter-office dealing, which allows the LME to operate as a 24-hour market. Trading on the floor takes place in two sessions daily, from 11:45 am to 1:05 pm and from 2:55 to 4:15 pm, London time. The two sessions are each broken down into two rings made up of five minutes’ trading in each contract. After the second ring of the first session the official prices for the day are announced. Contracts may be settled by offset or delivery and can be cleared in U.S. dollars, pounds sterling, Japanese yen and euros.

The LME is not a cash-cleared market. Both inter-office and floor trading are cleared and guaranteed by a system run by the London Clearing House, whose role is to act as a central counterparty to trades executed between clearing members and thereby reduce risk and settlement costs. The LME is subject to regulation by the FSA.

Copper has traded on the LME since its establishment.  The Copper contract traded on the LME was upgraded to High Grade Copper in November 1981 and again to the current Copper – Grade A contract in June 1986.  Copper trades on the LME in units of 25 metric tons and the settlement price of Copper for cash delivery is the price for the contract, expressed as U.S. dollars per metric ton, scheduled for same-day settlement.  Copper contracts on the LME may be established for delivery daily from one day (cash delivery) to three months, weekly on each Wednesday from three months to six months, and monthly on every third Wednesday from seven months to 63 months.

Zinc has traded on the LME unofficially since its establishment and officially since 1915, and the Zinc contract has undergone a number of upgrades, most recently to the current Special High Grade contract in June 1986.  Zinc trades on the LME in units of 25 metric tons and the settlement price of Zinc for cash delivery is the price for the contract, expressed as U.S. dollars per metric ton, scheduled for same-day settlement.  Zinc contracts on the LME may be established for delivery daily from one day (cash delivery) to three months, weekly on each Wednesday from three months to six months, and monthly on every third Wednesday from seven months to 27 months.

Historical Component Commodity Prices and Basket Return

The following charts show the daily Commodity Price for each Component Commodity, expressed as the U.S. dollar price per metric ton, on the LME from July 12, 2002 through July 13, 2007, using historical data obtained from Bloomberg Financial Markets; neither Lehman Brothers Inc. nor Lehman Brothers Holdings Inc. makes any representation or warranty as to the accuracy or completeness of these prices.  The historical data on the Commodity Prices are not necessarily indicative of the future performance of the Commodity Prices for the Component Commodities, the Basket Return, or what the value of the notes may be.  Fluctuations in the Commodity Prices for the Component Commodities make it difficult to predict whether or not the Basket Return will be greater or less than 0.000% and consequently whether the Redemption Amount payable at maturity will be greater than or equal to the principal amount invested.  Historical fluctuations in the Commodity Prices for the Component Commodities, and the resulting Basket Return, may be greater or lesser than fluctuations experienced by the holders of the notes.

The following chart shows the hypothetical daily historical Basket Return based on the hypothetical composite performance of the Commodity Prices for the Component Commodities on the LME, using historical data from July 12, 2002 through July 13, 2007, obtained from Bloomberg Financial Markets; neither Lehman Brothers Inc. nor Lehman Brothers Holdings Inc. makes any representation or warranty as to the accuracy or completeness of these prices.  For purposes of illustration only, the Basket Return shown in the chart below was indexed to a level of 0.0 on July 12, 2002, based upon the Commodity Prices for the Component Commodities on that day, and the composite value of the Component Commodities on any subsequent day was obtained by using the calculation of the Basket Return described above.

Under the terms of the notes and for purposes of calculating the Redemption Amount, the initial Basket Return will be indexed to a level of 0.0 on the Trade Date, based on the Commodity Strikes for the Component Commodities on the Trade Date.

Hypothetical Redemption Amount Payment Examples

If the Basket Return on the Valuation Date is greater than 0.0% on the Valuation Date, the Redemption Amount per $1,000 note payable on the Maturity Date will equal $1,000 plus the product of $1,000 and the Basket Return multiplied by the Participation Rate.  If the Basket Return on the Valuation Date is less than or equal to 0.0%, the Redemption Amount per $1,000 note payable on the Maturity Date will equal $1,000.

The table and examples below illustrate the hypothetical Redemption Amount at maturity per $1,000 in principal amount of notes, based on hypothetical values for the Basket Return of +100.0% to -100.0% and hypothetical Weighted Component Commodity Returns comprising the associated Basket Return (each of which values will be determined on the Valuation Date).  The examples below also assume a Participation Rate of 125.0% and Commodity Strike values of $7,967.50 for Copper and $3,545.50 for Zinc (each of which were set on the Trade Date).  The following results are based solely on the hypothetical examples cited; the trading performances of Copper and Zinc and the associated Basket Returns have been chosen arbitrarily for the purpose of these examples and should not be taken as indicative of the future performance of the Commodity Prices for the Component Commodities or of the Basket Return.  Numbers in the table and examples below have been rounded to two decimal places for ease of analysis.

Basket Return	Percentage Return  on Initial Investment	Redemption Amount  per $1,000 Note1
+100.00%	125.00%	$2,250.00
+50.00%	62.50%	$1,625.00
+30.00%	37.50%	$1,375.00
+25.00%	31.25%	$1,312.50
+20.00%	25.00%	$1,250.00
+15.00%	18.75%	$1,187.50
+10.00%	12.50%	$1,125.00
0.00%	0.00%	$1,000.00
–10.00%	0.00%	$1,000.00
–15.00%	0.00%	$1,000.00
–20.00%	0.00%	$1,000.00
–25.00%	0.00%	$1,000.00
–30.00%	0.00%	$1,000.00
–50.00%	0.00%	$1,000.00
–100.00%	0.00%	$1,000.00

1. If the Basket Return on the Valuation Date is greater than 0.0% on the Valuation Date, the Redemption Amount per $1,000 note will equal $1,000 + ($1,000 x Basket Return x Participation Rate).  If the Basket Return on the Valuation Date is less than or equal to 0.0%, the Redemption Amount per $1,000 note will equal $1,000.

The following examples illustrate the total returns set forth in the table above, based on various scenarios for the Basket Return:

Example 1:  Copper and Zinc each appreciate relative to their Component Commodity Strikes, resulting in a Basket Return of 10.0%.  Since the Basket Return is equal to 10.0% on the Valuation Date, the Redemption Amount, per $1,000 note, equals $1,000 + ($1,000 x 10.0% x 125.0%) or $1,125.

Component  Commodity	Commodity Strike  (on the Trade Date)	Final Commodity Price (on the Valuation Date)	Appreciation / Depreciation in Commodity Price		Component Commodity  Weighting		Weighted Component  Commodity Return
Copper	$7,967.50	$8,764.25	10.00%	*	1/2	=	5.00%
Zinc	$3,545.50	$3,900.05	10.00%	*	1/2	=	5.00%
				Basket Return		=	10.00%
			Redemption Amount			=	$1,125.00

Example 2:  Copper and Zinc each depreciate relative to their Commodity Strikes, resulting in a Basket Return of
–80.0%.  Since the Basket Return is equal to –80.0% on the Valuation Date, the Redemption Amount, per $1,000 note, equals $1,000.

Component Commodity	Commodity Strike (on the Trade Date)	Final Commodity Price (on the Valuation Date)	Appreciation / Depreciation in Commodity Price		Component Commodity Weighting		Weighted Component Commodity Return
Copper	$7,967.50	$796.75	–90.00%	*	1/2	=	–45.00%
Zinc	$3,545.50	$1,063.65	–70.00%	*	1/2	=	–35.00%
				Basket Return		=	–80.00%
			Redemption Amount			=	$1,000.00

Example 3:  Copper appreciates relative to its Commodity Strike, but Zinc depreciates relative to its Commodity Strike, resulting in a Basket Return of 20.0%.  Since the Basket Return is equal to 20.0% on the Valuation Date, the Redemption Amount, per $1,000 note, equals $1,000 + ($1,000 x 20.0% x 125.0%) or $1,250.

Component Commodity	Commodity Strike (on the Trade Date)	Final Commodity Price (on the Valuation Date)	Appreciation / Depreciation in Commodity Price		Component Commodity Weighting		Weighted Component Commodity Return
Copper	$7,967.50	$12,748.00	60.00%	*	1/2	=	30.00%
Zinc	$3,545.50	$2,836.40	–20.00%	*	1/2	=	–10.00%
			Basket Return			=	20.00%
			Redemption Amount			=	$1,250.00

13

Example 4:  Zinc appreciates relative to its Commodity Strike, but Copper depreciates relative to its Commodity Strikes, resulting in a Basket Return of –30.0%.  Since the Basket Return is equal to –30.0% on the Valuation Date, the Redemption Amount, per $1,000 note, equals $1,000.

Component Commodity	Commodity Strike (on the Trade Date)	Final Commodity Price (on the Valuation Date)	Appreciation / Depreciation in Commodity Price		Component Commodity Weighting		Weighted Component Commodity Return
Copper	$7,967.50	$1,593.50	–80.00%	*	1/2	=	–40.00%
Zinc	$3,545.50	$4,254.60	20.00%	*	1/2	=	10.00%
			Basket Return			=	–30.00%
			Redemption Amount			=	$1,000.00
