General

•

The securities are designed for investors who are mildly bearish, neutral or mildly bullish on the Underlyings. Investors should be willing to lose some or all of their investment if a Knock-In Event occurs with respect to either Underlying. Any payment on the securities is subject to our ability to pay our obligations as they become due.

•	Interest will be paid quarterly in arrears at a rate expected to be between 9.00% - 11.00% per annum (to be determined on the Trade Date), subject to Early Redemption. Interest will be calculated on a 30/360 basis.

•	The Issuer may redeem the securities, in whole but not in part, on any Interest Payment Date scheduled to occur on or after November 4, 2011. No interest will accrue or be payable following an Early Redemption.

•	Senior unsecured obligations of Credit Suisse AG, acting through its Nassau Branch, maturing May 4, 2012.†

•	Minimum purchase of $1,000. Minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.

•	The securities are expected to price on or about April 29, 2011 (the “Trade Date”) and are expected to settle on or about May 4, 2011. Delivery of the securities in book-entry form only will be made through The Depository Trust Company.

Key Terms

	Credit Suisse AG ("Credit Suisse"), acting through its Nassau Branch
Underlyings:	Each Underlying is identified in the table below, together with its Bloomberg ticker symbol, Initial Level and Knock-In Level:
	Underlying	Ticker	Initial Level	Knock-In Level
	Russell 2000® Index ("RTY")	RTY
	United States Natural Gas Fund, LP ("UNG")	UNG UP
Interest Rate:	Expected to be between 9.00% - 11.00% per annum (to be determined on the Trade Date). Interest will be calculated on a 30/360 basis.
Interest Payment Dates:	Unless redeemed earlier, interest will be paid quarterly in arrears on August 4, 2011, November 4, 2011, February 6, 2012 and the Maturity Date, subject to the modified following business day convention. No interest will accrue or be payable following an Early Redemption.
Redemption Amount:	At maturity, the Redemption Amount you will be entitled to receive will depend on the individual performance of each Underlying and whether a Knock-In Event occurs. If the securities are not subject to Early Redemption, the Redemption Amount will be determined as follows:
	• If a Knock-In Event occurs during the Observation Period, the Redemption Amount will equal the principal amount of the securities you hold multiplied by the sum of one plus the Underlying Return of the Lowest Performing Underlying. In this case, the maximum Redemption Amount will equal the principal amount of the securities. Therefore, unless the Final Level of each of the Underlyings is greater than or equal to its Initial Level, the Redemption Amount will be less than the principal amount of the securities and you could lose your entire investment.
	• If a Knock-In Event does not occur during the Observation Period, the Redemption Amount will equal the principal amount of the securities you hold.
	Any payment on the securities is subject to our ability to pay our obligations as they become due.
Early Redemption:	The Issuer may redeem the securities in whole, but not in part, on any Interest Payment Date scheduled to occur on or after November 4, 2011 upon at least three business days notice at 100% of the principal amount of the securities, together with the interest payable on that Interest Payment Date.
Knock-In Event:	A Knock-In Event will occur if the closing level of either Underlying reaches or falls below the Knock-In Level for that Underlying on any trading day during the Observation Period.
Knock-In Level:	The Knock-In Level for each Underlying will be approximately 65.00% of the Initial Level of such Underlying.
Lowest Performing Underlying:	The Underlying with the lowest Underlying Return.
Underlying Return:	For each Underlying, the Underlying Return will be calculated as follows:

Final Level – Initial Level

Initial Level

; subject to a maximum of zero

Initial Level:*	For each Underlying, the closing level of such Underlying on the Trade Date.
Final Level:	For each Underlying, the closing level of such Underlying on the Valuation Date.
Observation Period:	The period from but excluding the Trade Date to and including the Valuation Date.
Valuation Date:†	May 1, 2012
Maturity Date:†	May 4, 2012
Listing:	The securities will not be listed on any securities exchange.
CUSIP:	22546E3K8

*In the event that the closing level of either Underlying is not available on the Trade Date, the Initial Level for such Underlying will be determined on the immediately following trading day on which a closing level is available.

†The Valuation Date for either Underlying is subject to postponement if such date is not an underlying business day for such Underlying or as a result of a market disruption event in respect to such Underlying and the Maturity Date is subject to postponement if such date is not a business day or if the Valuation Date for either Underlying is postponed, in each case as described in the accompanying product supplement under "Description of the Securities-Market disruption events."

Our Central Index Key, or CIK, on the SEC website is 1053092. As used in this pricing supplement, the “Company,” “we,” “us,” or “our” refers to Credit Suisse.

This pricing supplement, together with the documents listed above, contains the terms of the securities and supersedes all other prior or contemporaneous oral statements as well as any other written materials including preliminary or indicative pricing terms, fact sheets, correspondence, trade ideas, structures for implementation, sample structures, brochures or other educational materials of ours. You should carefully consider, among other things, the matters set forth in “Risk Factors” in the product supplement and “Selected Risk Considerations” in this pricing supplement, as the securities involve risks not associated with conventional debt securities. You should consult your investment, legal, tax, accounting and other advisors before deciding to invest in the securities.

Hypothetical Redemption Amounts and Total Payments on the Securities

The tables and examples below illustrate hypothetical Redemption Amounts payable at maturity and, in the case of the tables, total payments over the term of the securities (which include both payments at maturity and the total interest paid on the securities) on a $1,000 investment in the securities for a range of Underlying Returns for the Lowest Performing Underlying, both in the event a Knock-In Event does not occur and in the event a Knock-In Event does occur. The tables and examples assume that (i) the securities are not redeemed prior to maturity, (ii) the Interest Rate applicable to the securities is 10.00% per annum (the midpoint of the expected range set forth on the cover of this pricing supplement), (iii) the term of the securities is exactly one year and (iv) the Knock-In Level for each Underlying is 65% of the Initial Level for such Underlying. In addition, the examples below assume that the Initial Level is 824 for RTY and $12 for UNG. The examples are intended to illustrate hypothetical calculations of only the Redemption Amount and do not illustrate the calculation or payment of any individual interest payment. The Redemption Amounts and total payment amounts set forth below are provided for illustration purposes only. The actual Redemption Amounts and total payments applicable to a purchaser of the securities will depend on several variables, including, but not limited to (a) whether the closing level of either Underlying is less than or equal to its respective Knock-In Level on any trading day during the Observation Period and (b) the Final Level of the Lowest Performing Underlying determined on the Valuation Date. It is not possible to predict whether a Knock-In Event will occur, and in the event that there is a Knock-In Event, whether and by how much the Final Level of the Lowest Performing Underlying will decrease in comparison to its Initial Level. Any payment on the securities is subject to our ability to pay our obligations as they become due. The numbers appearing in the following tables and examples have been rounded for ease of analysis.

TABLE 1: A Knock-In Event DOES NOT occur during the Observation Period.

Percentage Change from the Initial Level to the Final Level for the Lowest Performing Underlying	Underlying Return of the Lowest Performing Underlying	Redemption Amount per $1,000 Principal Amount of Securities (Knock-In Event does not occur)	Total Interest Payment per $1,000 Principal Amount of Securities	Total Payment per $1,000 Principal Amount of Securities

TABLE 2: A Knock-In Event DOES occur during the Observation Period.

Percentage Change from the Initial Level to the Final Level for the Lowest Performing Underlying	Underlying Return of the Lowest Performing Underlying	Redemption Amount per $1,000 Principal Amount of Securities (Knock-In Event occurs)	Total Interest Payment per $1,000 Principal Amount of Securities	Total Payment per $1,000 Principal Amount of Securities

-50%	-50%	$500	$100.00	$600.00

Example 1: A Knock-In Event occurs because the closing level of one Underlying reaches its Knock-In Level during the Observation Period; and the Final Level of the Lowest Performing Underlying is less than its Initial Level.

Underlying	Initial Level	Lowest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
RTY	824	824.00 (100% of Initial Level)	906.40 (110% of Initial Level)
UNG	$12	$7.80 (65% of Initial Level)	$7.80 (65% of Initial Level)

Since the closing level of UNG reaches its Knock-In Level during the Observation Period, a Knock-In Event occurs. UNG is also the Lowest Performing Underlying.

Therefore, the Underlying Return of the Lowest Performing Underlying will equal:

Final Level of UNG ― Initial Level of UNG

Initial Level of UNG

; subject to a maximum of 0.00

= ($7.80 – $12)/$12 = -0.350

Redemption Amount = principal amount of the securities × (1 + Underlying Return of the Lowest Performing Underlying)

= $1,000 x (1 – 0.350) = $650

Example 2: A Knock-In Event occurs because the closing level of one Underlying reaches its Knock-In Level during the Observation Period; the Lowest Performing Underlying never reaches or falls below its Knock-In Level during the Observation Period; and the Final Level of the Lowest Performing Underlying is less than its Initial Level.

Underlying	Initial Level	Lowest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
RTY	824	535.60 (65% of Initial Level)	906.40 (110% of Initial Level)
UNG	$12	$8.64 (72% of Initial Level)	$8.64 (72% of Initial Level)

Since the closing level of RTY reaches its Knock-In Level during the Observation Period, a Knock-In Event occurs. UNG is the Lowest Performing Underlying, even though its closing level never reaches or falls below its Knock-In Level during the Observation Period.

Therefore, the Underlying Return of the Lowest Performing Underlying will equal:

Final Level of UNG ― Initial Level of UNG

Initial Level of UNG

; subject to a maximum of 0.00

= ($8.64 – $12)/$12 = -0.280

Redemption Amount = principal amount of the securities × (1 + Underlying Return of the Lowest Performing Underlying)

= $1,000 x (1 – 0.280) = $720

Example 3: A Knock-In Event occurs because the closing level of one Underlying reaches its Knock-In Level during the Observation Period; and the Final Level of the Lowest Performing Underlying is greater than its Initial Level.

Underlying	Initial Level	Lowest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
RTY	824	535.60 (65% of Initial Level)	906.40 (110% of Initial Level)
UNG	$12	$11.40 (95% of Initial Level)	$14.40 (120% of Initial Level)

Since the closing level of RTY reaches its Knock-In Level, a Knock-In Event occurs. RTY is also the Lowest Performing Underlying.

Therefore, the Underlying Return of the Lowest Performing Underlying will equal:

Final Level of RTY ― Initial Level of RTY

Initial Level of RTY

; subject to a maximum of 0.00

= (906.40 – 824)/824 = 0.100

BUT 0.100 is greater than the maximum of 0.00, so the Underlying Return of the Lowest Performing Underlying is 0.00.

Redemption Amount = principal amount of the securities × (1 + Underlying Return of the Lowest Performing Underlying)

= $1,000 x (1 + 0.00) = $1,000

Example 4: A Knock-In Event does not occur.

Underlying	Initial Level	Lowest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
RTY	824	593.28 (72% of Initial Level)	906.40 (110% of Initial Level)
UNG	$12	$8.76 (73% of Initial Level)	$13.20 (110% of Initial Level)

Since the closing level of each Underlying did not reach or fall below its Knock-In Level during the Observation Period, a Knock-In Event does not occur.

Therefore, the Redemption Amount equals $1,000.

Selected Risk Considerations

An investment in the securities involves significant risks. Investing in the securities is not equivalent to investing directly in the Underlyings. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement.

YOU MAY RECEIVE LESS THAN THE PRINCIPAL AMOUNT AT MATURITY — You may receive less at maturity than you originally invested in the securities, or you may receive nothing, excluding any accrued or unpaid interest. If a Knock-In Event occurs during the Observation Period and the Final Level of the Lowest Performing Underlying is less than its Initial Level, you will be fully exposed to any depreciation in the Lowest Performing Underlying. In this case, the Redemption Amount you will be entitled to receive will be less than the principal amount of the securities and you could lose your entire investment. It is not possible to predict whether a Knock-In Event will occur, and in the event that there is a Knock-In Event, whether and by how much the Final Level of the Lowest Performing Underlying will decrease in comparison to its Initial Level. Any payment on the securities is subject to our ability to pay our obligations as they become due.

THE SECURITIES WILL NOT PAY MORE THAN THE PRINCIPAL AMOUNT, PLUS ACCRUED AND UNPAID INTEREST, AT MATURITY OR UPON EARLY REDEMPTION — The securities will not pay more than the principal amount, plus accrued and unpaid interest, at maturity or upon early redemption. If the Final Level of each Underlying is greater than its respective Initial Level (regardless of whether a Knock-In Event has occurred), you will not receive the appreciation of either Underlying. Assuming the securities are held to maturity and the term of the securities is exactly 1 year, the maximum amount payable with respect to the securities is expected to be between $1,090.00 and $1,110.00 (to be determined on the Trade Date) for each $1,000 principal amount of the securities.

THE SECURITIES ARE SUBJECT TO THE CREDIT RISK OF CREDIT SUISSE — Although the return on the securities will be based on the performance of the Underlyings, the payment of any amount due on the securities, including any applicable interest payments, early redemption payment or payment at maturity, is subject to the credit risk of Credit Suisse. Investors are dependent on our ability to pay all amounts due on the securities and, therefore, investors are subject to our credit risk. In addition, any decline in our credit ratings, any adverse changes in the market’s view of our creditworthiness or any increase in our credit spreads is likely to adversely affect the value of the securities prior to maturity.

THE REDEMPTION AMOUNT PAYABLE AT MATURITY WILL BE LESS THAN THE PRINCIPAL AMOUNT OF THE SECURITIES EVEN IF A KNOCK-IN EVENT OCCURS WITH RESPECT TO ONLY ONE UNDERLYING AND THE FINAL LEVEL OF ONLY ONE UNDERLYING FALLS BELOW ITS INITIAL LEVEL — Even if the closing level of only one Underlying reaches or falls below its Knock-In Level on any trading day during the Observation Period, a Knock-In Event will have occurred. In this case, the Redemption Amount payable at maturity will be less than the principal amount of the securities if, in addition to the occurrence of a Knock-In Event, the Final Level of just one Underlying falls below its Initial Level. This will be true even if the closing level of

the Lowest Performing Underlying never reached or fell below its Knock-In Level on any trading day during the Observation Period.

THE SECURITIES ARE SUBJECT TO A POTENTIAL EARLY REDEMPTION, WHICH WOULD LIMIT YOUR ABILITY TO ACCRUE INTEREST OVER THE FULL TERM OF THE SECURITIES —The securities are subject to a potential early redemption. The securities may be redeemed on any Interest Payment Date scheduled to occur on or after November 4, 2011 upon at least three business days notice. If the securities are redeemed prior to the Maturity Date, you will be entitled to receive the principal amount of your securities and any accrued but unpaid interest payable on such Interest Payment Date. In this case, you will lose the opportunity to continue to accrue and be paid interest from the date of Early Redemption to the scheduled Maturity Date. If the securities are redeemed prior to the Maturity Date, you may be unable to invest in other securities with a similar level of risk that yield as much interest as the securities.

SINCE THE SECURITIES ARE LINKED TO THE PERFORMANCE OF MORE THAN ONE UNDERLYING, YOU WILL BE FULLY EXPOSED TO THE RISK OF FLUCTUATIONS IN THE LEVEL OF EACH UNDERLYING — Since the securities are linked to the performance of more than one Underlying, the securities will be linked to the individual performance of each Underlying. Because the securities are not linked to a basket, in which case the risk is mitigated and diversified among all of the components of a basket, you will be exposed to the risk of fluctuations in the levels of the Underlyings to the same degree for each Underlying. For example, in the case of securities linked to a basket, the return would depend on the weighted aggregate performance of the basket components as reflected by the basket return. Thus, the depreciation of any basket component could be mitigated by the appreciation of another basket component, to the extent of the weightings of such components in the basket. However, in the case of securities linked to the lowest performing of each of two Underlyings, the individual performance of each Underlying is not combined to calculate your return and the depreciation of either Underlying is not mitigated by the appreciation of the other Underlying. Instead, if a Knock-In Event occurs, the Redemption Amount payable at maturity will depend on the lowest performing of the two Underlyings to which the securities are linked.

CERTAIN BUILT-IN COSTS ARE LIKELY TO ADVERSELY AFFECT THE VALUE OF THE SECURITIES PRIOR TO MATURITY — While the payment at maturity described in this pricing supplement is based on the full principal amount of your securities, the original issue price of the securities includes the agent’s commission and the cost of hedging our obligations under the securities through one or more of our affiliates. As a result, the price, if any, at which Credit Suisse (or its affiliates), will be willing to purchase securities from you in secondary market transactions, if at all, will likely be lower than the original issue price, and any sale prior to the Maturity Date could result in a substantial loss to you. The securities are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your securities to maturity.

LACK OF LIQUIDITY — The securities will not be listed on any securities exchange. Credit Suisse (or its affiliates) intends to offer to purchase the securities in the secondary market but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities when you wish to do so. Because other dealers are not likely to make a secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which Credit Suisse (or its affiliates) is willing to buy the securities. If you have to sell your securities prior to maturity, you may not be able to do so or you may have to sell them at a substantial loss.

POTENTIAL CONFLICTS — We and our affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and hedging our obligations under the securities. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the securities.

MANY ECONOMIC AND MARKET FACTORS WILL AFFECT THE VALUE OF THE SECURITIES — In addition to the levels of the Underlyings on any trading day during the Observation Period, the value of the securities will be affected by a number of economic and market factors that may either offset or magnify each other, including:

the expected volatility of the Underlyings;

the time to maturity of the securities;

the Early Redemption feature, which is likely to limit the value of the securities;

interest and yield rates in the market generally;

supply and demand for natural gas;

investors' expectations with respect to the rate of inflation;

geopolitical conditions and a variety of economic, financial, political, regulatory or judicial events that affect the components comprising the Underlyings, or markets generally and which may affect the levels of the Underlyings; and

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

Some or all of these factors may influence the price that you will receive if you choose to sell your securities prior to maturity. The impact of any of the factors set forth above may enhance or offset some or all of any change resulting from another factor or factors.

NO OWNERSHIP RIGHTS RELATING TO THE UNDERLYINGS — Your return on the securities will not reflect the return you would realize if you actually owned the shares of the United States Natural Gas Fund, LP (the "Fund") or the equity securities that comprise the Underlyings. The return on your investment, which is based on the percentage change in the Underlyings, is not the same as the total return you would receive based on the purchase of the shares of the Fund or the equity securities that comprise the Underlyings.

NO DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the securities, you will not have voting rights or rights to receive cash dividends or other distributions or other rights with respect to the shares of the Fund or the equity securities that comprise the Underlyings.

ANTI-DILUTION PROTECTION IS LIMITED — The calculation agent will make anti-dilution adjustments for certain events affecting the shares of the Fund. However, the calculation agent will not make an adjustment in response to all events that could affect the shares of the Fund. If an event occurs that does not require the calculation agent to make an adjustment, the value of the securities may be materially and adversely affected. See "Description of the Securities—Adjustments—For reference funds" in the accompanying product supplement for further information.

THERE ARE RISKS ASSOCIATED WITH THE FUND — Although shares of the Fund are listed for trading on a national securities exchange and a number of similar products have been traded on various national securities exchanges for varying periods of time, there is no assurance that an active trading market will continue for the shares of the Fund or that there will be liquidity in the trading market. The Fund is subject to management risk, which is the risk that a fund’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. Pursuant to the Fund's investment strategy or otherwise, the Fund's investment advisor may add, delete or substitute the equity securities held by the Fund it advises. Any of these actions could adversely affect the price of the shares of the Fund and consequently the value of the securities. For further information on the Fund, please refer to “The United States Natural Gas Fund, LP” in this pricing supplement.

COMMODITY PRICES ARE CHARACTERIZED BY HIGH AND UNPREDICTABLE VOLATILITY,

WHICH COULD LEAD TO A HIGH AND UNPREDICTABLE VOLATILITY IN THE PRICE FOR UNITS OF THE FUND— Market prices of the commodities and commodity futures contracts comprising the Fund tend to be highly volatile. Commodity market prices are not related to the value of a future income or earnings stream, as tends to be the case with fixed income and equity investments, but are subject to rapid fluctuations based on numerous factors, including changes in supply and demand relationships, governmental programs and policies, national and international monetary, trade, political and economic events, changes in interest and exchange rates, speculation and trading activities in commodities and related contracts, weather, and agricultural, trade, fiscal and exchange control policies. The markets for many commodities are also highly cyclical. These factors may have a larger impact on commodity prices and commodity linked instruments than on traditional fixed income and equity securities. These variables may create additional investment risks that cause the value of the securities to be more volatile than the values of traditional securities. These and other factors may affect the price of the Fund, and thus the value of your securities, in unpredictable or unanticipated ways. The high volatility and cyclical nature of commodity markets may render such an investment inappropriate as the focus of an investment portfolio.

GLOBAL ENERGY COMMODITY PRICES ARE PRIMARILY AFFECTED BY THE GLOBAL DEMAND FOR AND SUPPLY OF THESE COMMODITIES, BUT ARE ALSO SIGNIFICANTLY INFLUENCED BY SPECULATIVE ACTIONS AND BY CURRENCY EXCHANGE RATES – Prices for energy commodities, which includes natural gas, crude oil, heating oil, gasoline, and other petroleum-based fuels, are affected by governmental programs and policies, national and international political and economic events, changes in interest and exchange rates, trading activities in commodities and related contracts, trade, fiscal, monetary and exchange control policies and with respect to oil specifically, drought, floods, weather, government intervention, environmental policies, embargoes and tariffs. Demand for natural gas products by consumers, as well as by businesses, affects the price of such commodities. Sudden disruptions in the supplies of energy commodities, such as those caused by war, natural events, accidents or acts of terrorism, may cause prices of energy commodities futures contracts to become extremely volatile and unpredictable. Also, sudden and dramatic changes in the futures market may occur, for example, upon a cessation of hostilities that may exist in countries producing energy commodities, the introduction of new or previously withheld supplies into the market or the introduction of substitute products or commodities. Demand for energy commodities is generally linked to economic activity, and will tend to reflect general economic conditions.

THE SECURITIES ARE NOT SUBJECT TO REGULATION BY THE COMMODITY FUTURES TRADING COMMISSION — The proceeds to be received by us from the sale of the securities will not be used to purchase or sell any commodities futures contracts or options on futures contracts for your benefit. An investment in the securities thus does not constitute either an investment in futures contracts, options on futures contracts or in a collective investment vehicle that trades in these futures contracts (i.e., the securities will not constitute a direct or indirect investment by you in the futures contracts), and you will not benefit from the regulatory protections of the Commodity Futures Trading Commission, commonly referred to as the “CFTC.” The Issuer is not registered with the CFTC as a futures commission merchant and you will not benefit from the CFTC’s or any other non U.S. regulatory authority’s regulatory protections afforded to persons who trade in futures contracts on a regulated futures exchange through a registered futures commission merchant. Unlike an investment in the securities, an investment in a collective investment vehicle that invests in futures contracts on behalf of its participants may be subject to regulation as a commodity pool and its operator may be required to be registered with and regulated by the CFTC as a commodity pool operator, or qualify for an exemption from the registration requirement. Because the securities will not be interests in a commodity pool, the securities will not be regulated by the CFTC as a commodity pool, we will not be registered with the CFTC as a commodity pool operator, and you will not benefit from the CFTC’s or any non U.S. regulatory authority’s regulatory protections afforded to persons who invest in regulated commodity pools.

THE PERFORMANCE OF THE FUND MAY NOT FULLY REPLICATE THE PERFORMANCE OF NATURAL GAS – United States Commodity Funds, LLC, the general partner of the Fund, is responsible for investing the assets of the Fund in accordance with the objectives and policies of the Fund. The assets of the Fund consist primarily of investments in futures contracts for natural gas, crude oil, heating oil, gasoline, and other petroleum-based fuels that are traded on the New York Mercantile Exchange, ICE Futures or other U.S. and foreign exchanges (collectively, "natural gas futures contracts") and other natural gas-related investments such as cash-settled options on natural gas futures contracts and indices (collectively, “other natural gas interests” and together with natural gas futures contracts, “natural gas interests”). The Fund seeks to achieve its investment objective by investing in a mix of natural gas futures contracts and other natural gas interests such that changes in the net asset value of the Fund will closely track the changes in the price of a specified natural gas futures contract (the "benchmark natural gas futures contract"). The Fund's general partner believes that the benchmark natural gas futures contract historically has exhibited a close correlation with the spot price of natural gas. There is no assurance that the general partner of the Fund will successfully implement its investment strategy and there is a risk that changes in the price of the Fund units will not closely track changes in the spot price of natural gas. This could happen if the price of the units does not correlate closely with the Fund's net asset value; changes in the Fund's net asset value do not closely correlate with changes in the price of the benchmark natural gas futures contract; or changes in the price of the benchmark natural gas futures contract do not closely correlate with changes in the cash or spot price of natural gas.

RISKS ASSOCIATED WITH INVESTMENTS IN SECURITIES WITH CONCENTRATION IN THE NATURAL GAS INDUSTRY — The Fund invests in exchange-traded futures contracts for natural gas, crude oil, heating oil, gasoline and other petroleum-based fuels. The shares of the Fund may be subject to increased price volatility as they are linked to a single industry, market or sector and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that industry, market or sector.

The prices of these exchange-traded futures contracts are subject to the risks and hazards inherent in this industry, which that can cause prices to widely fluctuate. The exploration for, and production of, natural gas is an uncertain process with many risks. The cost of drilling, completing and operating wells for natural gas is uncertain, and a number of factors can delay or prevent drilling operations or production, including unexpected drilling conditions, pressure or irregularities in formations, equipment, failures or repairs, fires or other accidents, adverse weather conditions, pipeline ruptures or spills and shortages or delays in the availability of drilling rigs and the delivery of equipment. These prices are also subject to economic factors including supply and demand for natural gas, crude oil, heating oil, gasoline and other petroleum-based fuels; changes in interest rates; governmental, agricultural, trade, fiscal, monetary and exchange control programs and policies; weather and climate conditions; changing supply and demand relationships; changes in balances of payments and trade; U.S. and international rates of inflation; currency devaluations and revaluations; U.S. and international political and economic events; and changes in the views of market participants.
