PROSPECTUS

United States Brent Oil Fund^®, LP

45,450,000 Units

United States Brent Oil Fund, LP, a Delaware limited partnership, is a commodity pool that issues units that may be purchased and sold on the NYSE Arca, Inc. (“NYSE Arca”). United States Brent Oil Fund, LP is referred to as USBO throughout this document. The investment objective of USBO is for the daily changes in percentage terms of its units’ net asset value to reflect the daily changes in percentage terms of the spot price of Brent crude oil as measured by the daily changes in the price of the futures contract on Brent crude oil as traded on the ICE Futures Exchange that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case the futures contract will be the next month contract to expire, less USBO’s expenses.

The units may be purchased from USBO only in one or more blocks of 50,000 units as described in “Creation and Redemption of Units.” A block of 50,000 units is called a Basket. USBO issues and redeems Baskets called “creation baskets” or “redemption baskets”, as the case may be, from certain authorized purchasers as described in “Plan of Distribution.” The price of a creation baskets or a redemption basket is equal to the net asset value of 50,000 units on the day that the order to create the creation basket or redeem the redemption basket is accepted by the marketing agent.

Authorized purchasers that purchase creation baskets may offer and sell units from these baskets to the public at prices that are expected to reflect, among other factors, the trading price of units on the NYSE Arca, the net asset value of USBO and the supply and demand for units at the time of sale. The difference between the price paid by authorized purchasers as underwriters and the price paid to such authorized purchasers by investors will be deemed underwriting compensation. Authorized purchasers will not receive from USBO or any of its affiliates, any fee or other compensation in connection with the sale of units. USBO will continuously offer creation baskets consisting of 50,000 units to authorized purchasers through ALPS Distributors, Inc., which is the marketing agent. A list of USBO’s current authorized purchasers is available from the marketing agent. Authorized purchasers will pay a transaction fee of $350 through May 1, 2014 for each order to create one or more baskets; on May 2, 2014 and after, the transaction fee will be $1,000. The units are listed on the NYSE Arca under the symbol “BNO.”

USBO is not a mutual fund registered under the Investment Company Act of 1940 and is not subject to regulation under such Act.

Some of the risks of investing in USBO include:

• Investing in crude oil interests subjects USBO to the risks of the crude oil industry which could result in large fluctuations in the price of USBO’s units.

• If certain correlations do not exist, then investors may not be able to use USBO as a cost-effective way to invest indirectly in crude oil or as a hedge against the risk of loss in crude oil-related transactions.

• USBO does not expect to make cash distributions.

• USBO and its general partner may have conflicts of interest, which may permit them to favor their own interests to your detriment.

This is a best efforts offering; the marketing agent is not required to sell any specific number or dollar amount of units, but will use its best efforts to sell units. An authorized purchaser is under no obligation to purchase units. This is intended to be a continuous offering and is not expected to terminate until all of the registered units have been sold or three years from the date of the prospectus, whichever is earlier, although the offering may be temporarily suspended if and when no suitable investments for USBO are available or practicable. In no event may the aggregate compensation paid to the Marketing Agent and any affiliate of the General Partner for distribution related services in connection with this offering exceed ten percent (10%) of the gross proceeds of this offering.

Investing in USBO involves other significant risks. See “What Are the Risk Factors Involved with an Investment in USBO?” beginning on page 8 .

PROSPECTUS SUMMARY

This is only a summary of the prospectus and, while it contains material information about USBO and its units, it does not contain or summarize all of the information about USBO and the units contained in this prospectus that is material and/or which may be important to you. You should read this entire prospectus, including “What Are the Risk Factors Involved with an Investment in USBO?” beginning on page 8, before making an investment decision about the units.

Overview of USBO

United States Brent Oil Fund, LP, a Delaware limited partnership (“USBO” or “Us” or “We”), is a commodity pool that issues units that may be purchased and sold on the NYSE Arca. USBO is managed and controlled by its general partner, United States Commodity Funds LLC (formerly known as Victoria Bay Asset Management, LLC) (“General Partner”). The General Partner is a single member limited liability company formed in Delaware on May 10, 2005, that is registered as a commodity pool operator (“CPO”) with the Commodity Futures Trading Commission (“CFTC”) and is a member of the National Futures Association (“NFA”).

The net assets of USBO consist primarily of investments in futures contracts for crude oil, heating oil, gasoline, natural gas and other petroleum-based fuels that are traded on the ICE Futures Exchange, New York Mercantile Exchange (the “NYMEX”), or other U.S. and foreign exchanges (collectively, “Futures Contracts”), and to a lesser extent, in order to comply with regulatory requirements or in view of market conditions, other crude oil-related investments such as cash-settled options on Futures Contracts, forward contracts for crude oil, cleared swap contracts and over-the-counter transactions that are based on the price of crude oil and other petroleum-based fuels, Futures Contracts and indices based on the foregoing (collectively, “Other Crude Oil-Related Investments”). Market conditions that the General Partner currently anticipates could cause USBO to invest in Other Crude Oil-Related Investments include those allowing USBO to obtain greater liquidity or to execute transactions with more favorable pricing. For convenience and unless otherwise specified, Futures Contracts and Other Crude Oil-Related Investments collectively are referred to as “Crude Oil Interests” in this prospectus.

The investment objective of USBO is for the daily changes in percentage terms of its units’ net asset value (“NAV”) to reflect the daily changes in percentage terms of the spot price of Brent crude oil as measured by the daily changes in the price of the futures contract on Brent crude oil as traded on ICE Futures Exchange that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case the futures contract will be the next month contract to expire (the “Benchmark Futures Contract”), less USBO’s expenses. It is not the intent of USBO to be operated in a fashion such that its NAV will equal, in dollar terms, the dollar price of spot crude oil or any particular futures contract based on crude oil. It is not the intent of USBO to be operated in a fashion such that its NAV will reflect the percentage change of the price of any particular futures contract as measured over a time period greater than any day. The General Partner believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and other Crude-Oil Related Investments. USBO may invest in interests other than the Benchmark Futures Contract to comply with accountability levels and position limits. For a detailed discussion of accountability levels and position limits, see “What are Futures Contracts?”

In order for a hypothetical investment in units to break even over the next 12 months, assuming a selling price of $86.06 per unit, the investment would have to generate a 0.92% return. For more information, see “— Breakeven Analysis.”

The General Partner endeavors to place USBO’s trades in Futures Contracts and Other Crude Oil-Related-Investments and otherwise manage USBO’s investments so that “A” will be within plus/minus 10 percent of “B”, where:

• A is the average daily change in USBO’s NAV for any period of 30 successive valuation days, i.e., any NYSE Arca trading day as of which USBO calculates its NAV; and

• B is the average daily change in the price of the Benchmark Futures Contract over the same period.

The General Partner believes that market arbitrage opportunities cause daily changes in USBO’s unit price on the NYSE Arca to closely track daily changes in USBO’s NAV per unit. The General Partner further believes that the daily changes in prices of the Benchmark Future Contract have historically tracked the daily changes in the spot price of Brent crude oil. The General Partner believes that the net effect of these two expected relationships and the relationships described above between USBO’s NAV and the Benchmark Futures Contract will be the daily changes in the price of USBO’s units on NYSE Arca will closely track, in percentage terms, the daily changes in the spot price of Brent crude oil, less USBO’s expenses.

1

The General Partner employs a “neutral” investment strategy intended to track the changes in the price of the Benchmark Futures Contract regardless of whether the price goes up or goes down. USBO’s “neutral” investment strategy is designed to permit investors generally to purchase and sell USBO’s units for the purpose of investing indirectly in Brent crude oil in a cost-effective manner, and/or to permit participants in the crude oil or other industries to hedge the risk of losses in their Brent crude oil-related transactions. Accordingly, depending on the investment objective of an individual investor, the risks generally associated with investing in Brent crude oil and/or the risks involved in hedging may exist. In addition, an investment in USBO involves the risk that the changes in the price of USBO’s units will not accurately track the changes in the price of the Benchmark Futures Contract, and that changes in the Benchmark Futures Contract will not closely correlate with changes in the spot price of Brent crude oil. If the Benchmark Futures Contract does not correlate with the spot price of Brent crude oil, this could cause changes in the price of USBO’s units to substantially vary from the changes in the spot price of Brent crude oil. If this were to occur, then investors may not be able to effectively use USBO as a way to hedge against crude oil-related losses or as a way to indirectly invest in crude oil. In addition, the price relationship between the near month contract and the next month contract that compose the Benchmark Futures Contract will vary and may impact both the total return over time of USBO’s NAV, as well as the degree to which its total return tracks other crude oil price indices’ total returns.

The Benchmark Futures Contract is changed from the near month contract to the next month contract over a four-day period. Each month the Benchmark Futures Contract changes starting at the end of the day on the date two weeks prior to expiration of the near month contract for that month. The anticipated dates that the monthly four-day roll period will commence are posted on USBO’s website at www.unitedstatesbrentoilfund.com, and are subject to change without notice. During the first three days of the period, the applicable value of the Benchmark Futures Contract is based on a combination of the near month contract and the next month contract as follows: (1) day 1 consists of 75% of the then near month contract’s price plus 25% of the price of the next month contract, divided by 75% of the near month contract’s prior day’s price plus 25% of the price of the next month contract, (2) day 2 consists of 50% of the then near month contract’s price plus 50% of the price of the next month contract, divided by 50% of the near month contract’s prior day’s price plus 50% of the price of the next month contract, and (3) day 3 consists of 25% of the then near month contract’s price plus 75% of the price of the next month contract, divided by 25% of the near month contract’s prior day’s price plus 75% of the price of the next month contract. On day 4, the Benchmark Futures Contract is the next month contract to expire at that time and that contract remains the Benchmark Futures Contract until the beginning of the following month’s change in the Benchmark Futures Contract over a four-day period. On each day during the four-day period, the General Partner anticipates it will “roll” USBO’s positions in Crude Oil Interests by closing, or selling, a percentage of USBO’s positions in Crude Oil Interests and reinvesting the proceeds from closing those positions in new Crude Oil Interests that reflect the change in the Benchmark Futures Contract.

USBO issues units only in blocks of 50,000 units called Creation Baskets and redeems units only in blocks of 50,000 units called Redemption Baskets. Only Authorized Purchasers may purchase or redeem Creation Baskets or Redemption Baskets, respectively. An Authorized Purchaser is under no obligation to create or redeem baskets, and an Authorized Purchaser is under no obligation to offer to the public units of any baskets it does create. Baskets are generally created when there is a demand for units, including, but not limited to, when the market price per unit is at a premium to the NAV per unit. Authorized Purchasers will then sell such units, which will be listed on the NYSE Arca, to the public at per unit offering prices that are expected to reflect, among other factors, the trading price of the units on the NYSE Arca, the NAV of USBO at the time the Authorized Purchaser purchased the Creation Basket and the NAV at the time of the offer of the units to the public, the supply of and demand for units at the time of sale, and the liquidity of the Futures Contracts market and the market for Other Crude Oil-Related Investments. The prices of units offered by Authorized Purchasers are expected to fall between USBO’s NAV and the trading price of the units on the NYSE Arca at the time of sale. Similarly, Baskets are generally redeemed when the market price per unit is at a discount to the NAV per unit. Retail investors seeking to purchase or sell units on any day will effect such transactions in the secondary market, on the NYSE Arca, at the market price per unit, rather than in connection with the creation or redemption of Baskets.

There is no specified limit on the maximum amount of Creation Baskets that can be sold. At some point, accountability levels and position limits on certain of the Futures Contracts in which USBO intends to invest may practically limit the number of Creation Baskets that will be sold if the General Partner determines that the other investment alternatives available to USBO at that time will not enable it to meet its stated investment objective.

In managing USBO’s assets, the General Partner does not use a technical trading system that automatically issues buy and sell orders. The General Partner instead employs quantitative methodologies whereby each time one or more baskets are purchased or redeemed, the General Partner will purchase or sell Futures Contracts and Other Crude Oil-Related Investments with an aggregate market value that approximates the amount of Treasuries and/or cash received or paid upon the purchase or redemption of the Basket(s).

Note to Secondary Market Investors: The units can be directly purchased from or redeemed by USBO only in Creation Baskets or Redemption Baskets, respectively, and only by Authorized Purchasers. Each Creation Basket and Redemption Basket consists of 50,000 units and is expected to be worth millions of dollars. Individual investors, therefore, will not be able to directly purchase units from or redeem units with USBO. Some of the information contained in this prospectus, including information about buying and redeeming units directly from and to USBO is only relevant to Authorized Purchasers. Units are listed and traded on the NYSE Arca and may be purchased and sold as individual units. Individuals interested in purchasing units in the secondary market should contact their broker. Units purchased or sold through a broker may be subject to commissions.

Except when aggregated in Redemption Baskets, units are not redeemable securities. There is no guarantee that units will trade at or near the per-unit NAV.

Principal Investment Risks of an Investment in USBO

An investment in USBO involves a degree of risk. Some of the risks you may face are summarized below. A more extensive discussion of these risks appears beginning on page 8 .

• The price relationship between the near month contract to expire and the next month contract to expire that compose the Benchmark Futures Contract will vary and may impact both the total return over time of USBO’s NAV, as well as the degree to which its total return tracks the Benchmark Futures Contract. In cases in which the near month contract’s price is lower than the next month contract’s price (a situation known as “contango” in the futures market), then absent the impact of the overall movement in Brent crude oil prices the value of the Benchmark Futures Contract would tend to decline as it approaches expiration. In cases in which the near month contract’s price is higher than the next month contract’s price (a situation known as “backwardation” in the futures market), then absent the impact of the overall movement in Brent crude oil prices the value of the Benchmark Futures Contract would tend to rise as it approaches expiration. Assuming that spot crude oil prices remain unchanged, and ignoring the impact of transaction costs, taxes, or other fees and expenses, USBO’s total returns would tend to see a negative impact from the crude oil futures market being in contango and would tend to see a positive impact from the market being in backwardation.

• Unlike mutual funds, commodity pools or other investment pools that manage their investments in an attempt to realize income and gains and distribute such income and gains to their investors, USBO generally does not distribute cash to limited partners or other unitholders. You should not invest in USBO if you will need cash distributions from USBO to pay taxes on your share of income and gains of USBO, if any, or for any other reason.

• Investors may choose to use USBO as a means of investing indirectly in Brent crude oil and there are risks involved in such investments. The risks and hazards that are inherent in the crude oil industry may cause the price of crude oil to widely fluctuate.

• To the extent that investors use USBO as a means of investing indirectly in Brent crude oil, there is the risk that the daily changes in the price of USBO’s units on NYSE Arca will not closely track the daily changes in the spot price of Brent crude oil. This could happen if the price of units traded on the NYSE Arca does not correlate closely with USBO’s NAV; the changes in USBO’s NAV do not correlate closely with the changes in the price of the Benchmark Futures Contract; or the changes in the price of the Benchmark Futures Contract do not closely correlate with the changes in the cash or spot price of Brent crude oil. This is a risk because if these correlations do not exist, then investors may not be able to use USBO as a cost-effective way to invest indirectly in Brent crude oil or as a hedge against the risk of loss in crude oil-related transactions.

• The structure and operation of USBO may involve conflicts of interest. For example, a conflict may arise because the General Partner and its principals and affiliates may trade for themselves. In addition, the General Partner has sole current authority to manage the investments and operations of USBO, which may create a conflict with the unitholders’ best interests. The General Partner may also have a conflict to the extent that its trading decisions may be influenced by the effect they would have on the United States Oil Fund, LP (“USOF”), the United States Natural Gas Fund, LP (“USNG”), the United States 12 Month Oil Fund, LP (“US12OF”), the United States Gasoline Fund, LP (“UGA”), the United States Diesel-Heating Oil Fund, LP (“USDHO”), the United States Short Oil Fund, LP (USSO”), the United States 12 Month Natural Gas Fund, LP (“US12NG”), the United States Commodity Index Fund (“USCI”), the United States Metals Index Fund (“USMI”), the United States Agriculture Index Fund (“USAG”), the United States Copper Index Fund (“CPER”), and the United States Asian Commodities Basket Fund (“UAC”), or any other commodity pool the General Partner may form and manage in the future. UAC has been declared effective by the regulatory agencies which have regulatory authority over the General Partner and UAC, but at the time of filing this, UAC has not been made available to the public. USOF, USNG, US12OF, UGA, USDHO, USSO, US12NG, USCI, USMI, USAG, CPER and UAC are referred to herein as the “Related Public Funds.”

• USBO invests primarily in Futures Contracts, and particularly in Futures Contracts traded on the ICE Futures Exchange, which involves certain risks including that changes in its NAV may not correlate with changes in the Benchmark Futures Contract.

• USBO invests primarily in Futures Contracts that are traded outside the United States. Some non-U.S. markets present risks because they are not subject to the same degree of regulation as their U.S. counterparts. In some of these non-U.S. markets, the performance on a contract is the responsibility of the counterparty and is not backed by an exchange or clearing corporation and therefore exposes USBO to credit risk. However, Futures Contracts traded on the ICE Futures Exchange, including the Benchmark Futures Contract, are backed by the ICE Futures Exchange and do not expose USBO to the risks of some other non-U.S. exchanges or clearing corporations. Trading in non-U.S. markets also leaves USBO susceptible to fluctuations in the value of the local currency against the U.S. dollar for contracts not traded in U.S. dollars. The Benchmark Futures Contract, however, is traded in U.S. dollars and does not expose USBO to the risk of currency fluctuations.

3

• You will have no rights to participate in the management of USBO and will have to rely on the duties and judgment of the General Partner to manage USBO.

• USBO pays fees and expenses that are incurred regardless of whether it is profitable.

• USBO seeks to have the daily changes in its units’ NAV in percentage terms track the daily changes in the price of Brent crude oil in percentage terms rather than profit from speculative trading of Crude Oil Interests. The General Partner therefore endeavors to manage USBO’s positions in Crude Oil Interests so that USBO’s assets are, unlike those of other commodity pools, not leveraged ( i.e., so that the aggregate value of USBO’s unrealized losses from its investments in such Crude Oil Interests at any time will not exceed the value of USBO’s assets). There is no assurance that the General Partner will successfully implement this investment strategy. If the General Partner permits USBO to become leveraged, and if USBO’s trading positions suddenly turn unprofitable, you could lose all or substantially all of your investment. These movements in price may be the result of factors outside of the General Partner’s control and may not be anticipated by the General Partner.

• USBO may also invest in Other Crude Oil-Related Investments, many of which are negotiated contracts that are not as liquid as Futures Contracts and expose USBO to credit risk that its counterparty may not be able to satisfy its obligations to USBO.

• Regulation of the commodity interest and energy markets is extensive and constantly changing. On July 21, 2010, a broad financial regulatory reform bill, “The Dodd-Frank Wall Street Reform and Consumer Protection Act,” was signed into law that includes provisions altering the regulation of commodity interests. The CFTC, the SEC and other federal regulators, have been tasked with developing the rules and regulations enacting the provisions noted above. The new law and the rules currently being promulgated thereunder may negatively impact USBO’s ability to meet its investment objective, either through limits or requirements imposed on it or upon its counterparties.

• Cash or property will be distributed at the sole discretion of the General Partner, and the General Partner currently does not intend to make cash or other distributions with respect to units. You will be required to pay U.S. federal income tax and, in some cases, state, local or foreign income tax on your allocable share of USBO’s taxable income, without regard to whether you receive distributions or the amount of any distributions. Therefore, your tax liability with respect to your units may exceed the amount of cash or value of property (if any) distributed.

Breakeven Analysis

The breakeven analysis below indicates the approximate dollar returns and percentage required for the redemption value of a hypothetical investment in a single unit to equal the amount invested twelve months after the investment was made. For purposes of this breakeven analysis, we have assumed an initial selling price per unit of $86.06, which equals the net asset value per unit on January 31, 2013. This breakeven analysis refers to the redemption of baskets by Authorized Purchasers and is not related to any gains an individual investor would have to achieve in order to break even. The breakeven analysis is an approximation only.

(1) USBO is contractually obligated to pay the General Partner a management fee based on daily net assets and paid monthly of 0.75% per annum on average daily net assets.

(2) Authorized Purchasers are required to pay a Creation Basket fee of $350 for each order they place to create one or more baskets. An order must be at least one basket, which is 50,000 units. This breakeven analysis assumes a hypothetical investment in a single unit so the Creation Basket fee is $.01 (350/50,000).

(3) This amount is based on the actual brokerage fees for USBO calculated on an annualized basis.

(4) USBO earns interest on funds it deposits with the futures commission merchant and the custodian and it estimates that the interest rate will be 0.07% based on the current interest rate on three-month Treasury Bills as of January 31, 2013. The actual rate may vary.

(5) The foregoing assumes that the assets of USBO are aggregated with those of USOF, USNG, US12OF, UGA, USDHO, USSO, US12NG, USMI, USAG, USCI and CPER, that the aggregate fees paid to the independent directors in 2012 was $540,586, that the allocable portion of the fees borne by USBO equals $9,844, and that USBO has $47,334,729 in assets, which is the amount of assets as of January 31, 2013.

(6) USBO assumed the aggregate costs attributable to tax accounting and reporting for 2012 was $75,000. The number in the break-even table assumes USBO has $47,334,729 in assets which is the amount of assets as of January 31, 2013.

THE OFFERING

Offering: USBO is offering Creation Baskets consisting of 50,000 units through ALPS Distributors, Inc. (“Marketing Agent”) as marketing agent to Authorized Purchasers. Authorized Purchasers may purchase Creation Baskets consisting of 50,000 units at USBO’s NAV. This is a continuous offering under Rule 415 of the Securities Act of 1933 (“1933 Act”) and is not expected to terminate until all of the registered units have been sold or three years from the date of the prospectus, whichever is earlier, although the offering may be temporarily suspended during such period when suitable investments for USBO are not available or practicable. It is anticipated that when all registered units have been sold pursuant to this registration statement, additional units will be registered in subsequent registration statements.

Use of Proceeds: The General Partner applies substantially all of USBO’s assets toward trading in Futures Contracts and Other Crude Oil-Related Investments, and investing in Treasuries, cash and/or cash equivalents. The General Partner deposits a portion of USBO’s net assets with the futures commission merchant, UBS Securities LLC, or other custodian to be used to meet its current or potential margin or collateral requirements in connection with its investment in Futures Contracts and Other Crude Oil-Related Investments. USBO uses only Treasuries, cash and/or cash equivalents to satisfy these requirements. The General Partner believes that all entities that hold or trade USBO’s assets are based in the United States and are subject to United States regulations. Approximately 5% to 30% of USBO’s assets will be committed as margin for Futures Contracts and collateral for Other Crude Oil-Related Investments. However, from time to time, the percentage of assets committed as margin/collateral may be substantially more, or less, than such range. The remaining portion of USBO’s assets is held in Treasuries, cash and/or cash equivalents by its custodian, Brown Brothers Harriman & Co. (the “Custodian”). All interest income earned on these investments is retained for USBO’s benefit.

NYSE Arca Symbol: “BNO”

Creation and Redemption: Currently and through May 1, 2014, Authorized Purchasers pay a $350 fee for each order to create or redeem one or more Creation Baskets or Redemption Baskets; on and after May 2, 2014, the fee is $1,000. Authorized Purchasers are not required to sell any specific number or dollar amount of units. The per unit price of units offered in Creation Baskets on any particular day is the total NAV of USBO calculated shortly after the close of the core trading on the NYSE Arca on that day divided by the number of issued and outstanding units. The General Partner shall notify the Depository Trust Company (“DTC”) of any change in the transaction fee and will not implement any increase in the fee for Creation or Redemption Baskets until 30 days after the date of notice.

Registration, Clearance and Settlement: Individual certificates will not be issued for the units. Instead, units will be represented by one or more global certificates, which will be deposited by the Custodian with the DTC and registered in the name of Cede & Co., as nominee for DTC.

The administrator, Brown Brothers Harriman & Co. (“Administrator”), has been appointed registrar and transfer agent for the purpose of registering and transferring units. The General Partner will recognize transfer of units only if such transfer is done in accordance with the LP Agreement, including the delivery of a transfer application.

Net Asset Value: The NAV is calculated by taking the current market value of USBO’s total assets, subtracting any liabilities and dividing that number by the total number of outstanding units. Under USBO’s current operational procedures, the Administrator calculates the NAV of USBO once each NYSE Arca trading day. The NAV for a particular trading day is released after 4:00 p.m. New York time. Trading during the core trading session of the NYSE Arca typically closes at 4:00 p.m. New York time. The Administrator uses the ICE Futures Exchange settlement price (a weighted average price of trades during a three minute settlement period from 2:27 p.m. to 2:30 p.m. New York time) for the contracts traded on the ICE Futures Exchange, but calculates or determines the value of all other USBO investments as of the earlier of the close of the NYSE Arca or 4:00 p.m. New York time.

6

Fund Expenses: USBO pays the General Partner a management fee of 0.75% of NAV on its average net assets. Brokerage fees for Treasuries, Futures Contracts, and Other Crude Oil-Related Investments were 0.071% of average net assets on an annualized basis and were paid to unaffiliated brokers. USBO also pays any licensing fees for the use of intellectual property. Registration fees paid to the SEC, FINRA, or other regulatory agency in connection with the initial offers and sales of the units and the legal, printing, accounting and other expenses associated with such registrations were paid by the General Partner, but the fees and expenses associated with subsequent SEC registrations of units are borne by USBO. USBO also is responsible for the fees and expenses, which may include directors and officers liability insurance, of the independent directors of the General Partner in connection with their activities with respect to USBO. These director fees and expenses may be shared with other funds managed by the General Partner. These fees and expenses, in total amounted to $540,586 for all funds for 2012, and USBO’s portion of such fees and expenses was $9,844, although this amount may change in future years. The General Partner, and not USBO, is responsible for payment of the fees of USBO’s Marketing Agent, Administrator and Custodian. USBO and/or the General Partner may be required to indemnify the Marketing Agent, Administrator or Custodian under certain circumstances. USBO also pays the fees and expenses associated with its tax accounting and reporting requirements with the exception of certain initial implementation services fees and base services fees which were paid by the General Partner. The General Partner, though under no obligation to do so, agreed to pay certain expenses, including those relating to audit expenses and tax accounting and reporting requirements normally borne by USBO to the extent that such expenses exceeded 0.15% (15 basis points) of USBO’s NAV, on an annualized basis. The General Partner has no obligation to continue such payment into subsequent years. The total amount of expense waiver was $47,248 for the year ended December 31, 2012.

Termination Events: USBO shall continue in effect from the date of its formation in perpetuity, unless sooner terminated upon the occurrence of any one or more of the following events: the death, adjudication of incompetence, bankruptcy, dissolution, withdrawal, or removal of a General Partner who is the sole remaining General Partner, unless a majority in interest of limited partners within ninety (90) days after such event elects to continue the partnership and appoints a successor general partner or the affirmative vote of a majority in interest of the limited partners subject to certain conditions. Upon termination of the partnership, the affairs of the partnership shall be wound up and all of its debts and liabilities discharged or otherwise provided for in the order of priority as provided by law. The fair market value of the remaining assets of the partnership shall then be determined by the General Partner. Thereupon, the assets of the partnership shall be distributed pro rata to the partners in accordance with their units.

Withdrawal: As discussed in the LP Agreement, if the General Partner gives at least fifteen (15) days’ written notice to a limited partner, then the General Partner may for any reason, in its sole discretion, require any such limited partner to withdraw entirely from the partnership or to withdraw a portion of its partner capital account. If the General Partner does not give at least fifteen (15) days’ written notice to a limited partner, then it may only require withdrawal of all or any portion of the capital account of any limited partner in the following circumstances: (i) the unitholder made a misrepresentation to the General Partner in connection with its purchase of units; or (ii) the limited partner’s ownership of units would result in the violation of any law or regulation applicable to the partnership or a partner.

7

Authorized Purchasers: USBO has entered into agreements with several Authorized Purchasers. A current list of Authorized Purchasers is available from the Marketing Agent. Authorized Purchasers must be (1) registered broker-dealers or other securities market participants, such as banks and other financial institutions, that are not required to register as broker-dealers to engage in securities transactions, and (2) DTC Participants. To become an Authorized Purchaser, a person must enter into an Authorized Purchaser Agreement with the General Partner.

WHAT ARE THE RISK FACTORS INVOLVED WITH AN INVESTMENT IN USBO?

You should consider carefully the risks described below before making an investment decision. You should also refer to the other information included in this prospectus, as well as information found in our periodic reports, which include USBO’s financial statements and the related notes, that are incorporated by reference. See “Incorporation by Reference of Certain Information.”

Risks Associated With Investing Directly or Indirectly in Crude Oil

Investing in Crude Oil Interests subjects USBO to the risks of the crude oil industry and this could result in large fluctuations in the price of USBO’s units.

USBO is subject to the risks and hazards of the crude oil industry because it invests in Crude Oil Interests. The risks and hazards that are inherent in the crude oil industry may cause the price of crude oil to widely fluctuate. If the changes in percentage terms of USBO’s units accurately track the changes in percentage terms of the Benchmark Futures Contract or the spot price of Brent crude oil, then the price of its units may also fluctuate. The exploration and production of crude oil are uncertain processes with many risks. The cost of drilling, completing and operating wells for crude oil is often uncertain, and a number of factors can delay or prevent drilling operations or production of crude oil, including:

• unexpected drilling conditions;

• pressure or irregularities in formations;

• equipment failures or repairs;

• fires or other accidents;

• adverse weather conditions;

• pipeline ruptures, spills or other supply disruptions; and

• shortages or delays in the availability of drilling rigs and the delivery of equipment.

Crude oil transmission, distribution, gathering, and processing activities involve numerous risks that may affect the price of crude oil.

There are a variety of hazards inherent in crude oil transmission, distribution, gathering, and processing, such as leaks, explosions, pollution, release of toxic substances, adverse weather conditions (such as hurricanes and flooding), pipeline failure, abnormal pressures, uncontrollable flows of crude oil, scheduled and unscheduled maintenance, physical damage to the gathering or transportation system, and other hazards which could affect the price of crude oil. To the extent these hazards limit the supply or delivery of crude oil, crude oil prices will increase.

Changes in the political climate could have negative consequences for crude oil prices.

Uprise in the Middle East, including civil war in Syria and uprise in Egypt could put oil exports in jeopardy. As global markets continue to react to various crises and uprises, such unrests in general could impact the production, supply and cost of crude oil.

Fluctuations in the reserve capacity of crude oil could impact future prices.

In the past, a supply disruption in one area of the world was softened by the ability of major oil-producing nations to increase output to make up the difference. At this time, some of that spare reserve capacity has been absorbed by increased demand.

Daily changes in USBO’s per unit NAV may not correlate with daily changes in the price of the Benchmark Futures Contract. If this were to occur, investors may not be able to effectively use USBO as a way to hedge against crude oil-related losses or as a way to indirectly invest in crude oil.

The General Partner endeavors to invest USBO’s assets as fully as possible in Futures Contracts and Other Crude Oil-Related Investments so that the daily changes in percentage terms of the per unit NAV closely correlate with the daily changes in percentage terms in the price of the Benchmark Futures Contract. However, daily changes in USBO’s per unit NAV may not correlate with the daily changes in the price of the Benchmark Futures Contract for several reasons as set forth below:

8

• USBO: (i) may not be able to buy/sell the exact amount of Futures Contract and Other Crude Oil-Related Investments to have a perfect correlation with per unit NAV; (ii) may not always be able to buy and sell Futures Contracts or Other Crude Oil-Related Investments at the market price; and (iii) is required to pay fees, including brokerage fees and the management fee, which will have an effect on the correlation.

• Short-term supply and demand for crude oil may cause the changes in the market price of the Benchmark Futures Contract to vary from the changes in USBO’s per unit NAV if USBO has fully invested in Futures Contracts that do not reflect such supply and demand and it is unable to replace such contracts with Futures Contracts that do reflect such supply and demand.

• USBO sells and buys only as many Futures Contracts and Other Crude Oil-Related Investments that it can to get the daily changes in percentage terms of the per unit NAV as close as possible to the daily changes in percentage terms in the price of the Benchmark Futures Contracts. The remainder of its assets are invested in Treasuries, cash and/or cash equivalents and are used to satisfy initial margin and additional margin requirements, if any, and to otherwise support its investments in Crude Oil Interests. Investments in Treasuries, cash and/or cash equivalents, both directly and as margin, provide rates of return that vary from changes in the price of the Benchmark Futures Contract.

• Because USBO incurs certain expenses in connection with its investment activities, and holds most of its assets in cash and/or more liquid short-term securities for margin and other liquidity purposes and for redemptions that may be necessary on an ongoing basis, the General Partner is generally not able to fully invest USBO’s assets in Futures Contracts or Other Crude Oil-Related Investments and there cannot be perfect correlation between changes in USBO’s per unit NAV and changes in the price of the Benchmark Futures Contract.

• As USBO grows, there may be more or less correlation. For example, if USBO only has enough money to buy three Benchmark Futures Contracts and it needs four contracts to track the price of Brent crude oil then the correlation will be lower, but if buys 20,000 Benchmark Futures Contracts and it needs to buy 20,001 contracts then the correlation will be higher. At certain asset levels, USBO may be limited in its ability to buy or purchase the Benchmark Futures Contract or other Futures Contracts due to accountability levels imposed by the relevant exchanges. To the extent that USBO invests in these other Futures Contracts or Other Crude Oil-Related Investments, the correlation with the Benchmark Futures Contract may be lower. If USBO is required to invest in other Futures Contracts and Other Crude Oil-Related Investments that are less correlated with the Benchmark Futures Contract, USBO would likely invest in over-the-counter contracts to increase the level of correlation of USBO’s assets. Over-the-counter contracts entail certain risks described below under “Over-the-Counter Contract Risk.”

• USBO may not be able to buy the exact number of Futures Contracts and Other Crude Oil-Related Investments to have a perfect correlation with the Benchmark Futures Contract if the purchase price of the Futures Contracts required to be fully invested in such contracts is higher than the proceeds received for the sale of a Creation Basket on the day the basket was sold. In such case, USBO could not invest the entire proceeds from the purchase of the Creation Basket in such futures contracts (for example, assume USBO receives $2,500,000 for the sale of a Creation Basket and assume that the price of a Futures Contract for crude oil is $105,000, then USBO could only invest in 23 Futures Contracts with an aggregate value of $2,415,000), USBO would be required to invest a percentage of the proceeds in cash, Treasuries or other liquid securities to be deposited as margin with the futures commission merchant through which the contracts were purchased. The remainder of the purchase price for the Creation Basket would remain invested in Treasuries, cash and/or cash equivalents or other liquid securities as determined by the General Partner from time to time based on factors such as potential calls for margin or anticipated redemptions. If the trading market for Futures Contracts is suspended or closed, USBO may not be able to purchase these investments at the last reported price.

If daily changes in USBO’s per unit NAV do not correlate with daily changes in the price of the Benchmark Futures Contract, then investing in USBO may not be an effective way to hedge against oil-related losses or indirectly invest in oil.

9

The Benchmark Futures Contract may not correlate with the spot price of Brent crude oil and this could cause changes in the price of the units to substantially vary from the changes in the spot price of Brent crude oil. If this were to occur, then investors may not be able to effectively use USBO as a way to hedge against crude oil-related losses or as a way to indirectly invest in crude oil. In addition, the price relationship between the near month contract and the next month contract that compose the Benchmark Futures Contract will vary and may impact both the total return over time of USBO’s per unit NAV, as well as the degree to which its total return tracks other crude oil price indices’ total returns.

When using the Benchmark Futures Contract as a strategy to track the spot price of Brent crude oil, at best the correlation between changes in prices of such Crude Oil Interests and the spot price of Brent crude oil can be only approximate. The degree of imperfection of correlation depends upon circumstances such as variations in the speculative Brent crude oil market, supply of and demand for such Crude Oil Interests and technical influences in futures trading. If there is a weak correlation between the Crude Oil Interests and the spot price of Brent crude oil, then even in situations where there is also tracking among the price of units, the per unit NAV of such units and Crude Oil Interests, the price of units may not accurately track the spot price of Brent crude oil and investors may not be able to effectively use USBO as a way to hedge the risk of losses in their oil-related transactions or as a way to indirectly invest in crude oil.

Backwardation and contango may increase USBO’s tracking error and/or negatively impact total return.

The design of USBO’s Benchmark Futures Contract is such that every month it begins by using the near month contract to expire until the near month contract is within two weeks of expiration, when, over a four day period, it transitions to the next month contract to expire as its benchmark contract and keeps that contract as its benchmark until it becomes the near month contract and close to expiration. In the event of a crude oil futures market where near month contracts trade at a higher price than next month to expire contracts, a situation described as “backwardation” in the futures market, then absent the impact of the overall movement in crude oil prices the value of the benchmark contract would tend to rise as it approaches expiration. As a result, the total return of the Benchmark Futures Contract would tend to track higher. Conversely, in the event of a crude oil futures market where near month contracts trade at a lower price than next month contracts, a situation described as “contango” in the futures market, then absent the impact of the overall movement in crude oil prices the value of the Benchmark Futures Contract would tend to decline as it approaches expiration. As a result the total return of the Benchmark Futures Contract would tend to track lower. When compared to total return of other price indices, such as the spot price of crude oil, the impact of backwardation and contango may lead the total return of USBO’s per unit NAV to vary significantly. In the event of a prolonged period of contango, and absent the impact of rising or falling oil prices, this could have a significant negative impact on USBO’s per unit NAV and total return.

USBO may experience a loss if it is required to sell Treasuries at a price lower than the price at which they were acquired.

The value of Treasuries generally moves inversely with movements in interest rates. If USBO is required to sell Treasuries at a price lower than the price at which they were acquired, USBO will experience a loss. This loss may adversely impact the price of the units and may decrease the correlation among the price of units, the per unit NAV of units, the price of the Benchmark Futures Contract and Other Crude Oil-Related Investments, and the spot price of Brent crude oil.

Certain of USBO’s investments could be illiquid which could cause large losses to investors at any time or from time to time.

USBO may not always be able to liquidate its positions in its investments at the desired price. It is difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. A market disruption, such as a foreign government taking political actions that disrupt the market in its currency, its crude oil production or exports, or in another major export, can also make it difficult to liquidate a position. Alternatively, limits imposed by futures exchanges or other regulatory organizations, such as accountability levels, position limits and daily price fluctuation limits, may contribute to a lack of liquidity with respect to some commodity interests.

Unexpected market illiquidity may cause major losses to investors at any time or from time to time. In addition, USBO has not and does not intend at this time to establish a credit facility, which would provide an additional source of liquidity and instead relies only on the Treasuries, cash and/or cash equivalents that it holds. The anticipated large value of the positions in Futures Contracts that the General Partner will acquire or enter into for USBO increases the risk of illiquidity. The Other Crude Oil-Related Investments that USBO invests in, such as negotiated over-the-counter contracts, may have a greater likelihood of being illiquid since they are contracts between two parties that take into account not only market risk, but also the relative credit, tax, and settlement risks under such contracts. Such contracts also have limited transferability that results from such risks and from the contract’s express limitations.

Because both Futures Contracts and Other Crude Oil-Related Investments may be illiquid, USBO’s Crude Oil Interests may be more difficult to liquidate at favorable prices in periods of illiquid markets and losses may be incurred during the period in which positions are being liquidated.

10

If the nature of hedgers and speculators in futures markets has shifted such that crude oil purchasers are the predominant hedgers in the market, USBO might have to reinvest at higher futures prices or choose Other Crude Oil-Related Investments.

The changing nature of the hedgers and speculators in the crude oil market influences whether futures prices are above or below the expected future spot price. In order to induce speculators to take the corresponding long side of the same futures contract, crude oil producers must generally be willing to sell futures contracts at prices that are below expected future spot prices. Conversely, if the predominant hedgers in the futures market are the purchasers of the crude oil who purchase futures contracts to hedge against a rise in prices, then speculators will only take the short side of the futures contract if the futures price is greater than the expected future spot price of crude oil. This can have significant implications for USBO when it is time to reinvest the proceeds from a maturing Futures Contract into a new Futures Contract.

While USBO does not intend to take physical delivery of crude oil under its Futures Contracts, physical delivery under such contracts impacts the value of the contracts.

While it is not the current intention of USBO to take physical delivery of crude oil under any of its Futures Contracts, futures contracts are not required to be cash-settled and it is possible to take delivery under some of these contracts. Storage costs associated with purchasing crude oil could result in costs and other liabilities that could impact the value of Futures Contracts or Other Crude Oil-Related Investments. Storage costs include the time value of money invested in crude oil as a physical commodity plus the actual costs of storing the crude oil less any benefits from ownership of crude oil that are not obtained by the holder of a futures contract. In general, Futures Contracts have a one-month delay for contract delivery and the back month (the back month is any future delivery month other than the spot month) includes storage costs. To the extent that these storage costs change for crude oil while USBO holds Futures Contracts or Other Crude Oil-Related Investments, the value of the Futures Contracts or Other Crude Oil-Related Investments, and therefore USBO’s per unit NAV, may change as well.

Regulation of the commodity interests and energy markets is extensive and constantly changing; future regulatory developments are impossible to predict but may significantly and adversely affect USBO.

The futures markets are subject to comprehensive statutes, regulations, and margin requirements. In addition, the CFTC and the exchanges are authorized to take extraordinary actions in the event of a market emergency, including, for example, the retroactive implementation of speculative position limits or higher margin requirements, the establishment of daily price limits and the suspension of trading.

The regulation of commodity interest transactions in the United States is a rapidly changing area of law and is subject to ongoing modification by governmental and judicial action. Considerable regulatory attention has been focused on non-traditional investment pools that are publicly distributed in the United States. In addition, various national governments outside of the United States have expressed concern regarding the disruptive effects of speculative trading in the energy markets and the need to regulate the derivatives markets in general. The effect of any future regulatory change on USBO is impossible to predict, but it could be substantial and adverse.

Investing in USBO for purposes of hedging may be subject to several risks including the possibility of losing the benefit of favorable market movement.

Participants in the crude oil or in other industries may use USBO as a vehicle to hedge the risk of losses in their crude oil-related transactions. There are several risks in connection with using USBO as a hedging device. While hedging can provide protection against an adverse movement in market prices, it can also preclude a hedger’s opportunity to benefit from a favorable market movement. In a hedging transaction, the hedger may be concerned that the hedged item will increase in price, but must recognize the risk that the price may instead decline and if this happens he will have lost his opportunity to profit from the change in price because the hedging transaction will result in a loss rather than a gain. Thus, the hedger foregoes the opportunity to profit from favorable price movements.

An investment in USBO may provide little or no diversification benefits. Thus, in a declining market, USBO may have no gains to offset losses from other investments, and an investor may suffer losses on an investment in USBO while incurring losses with respect to other asset classes.

Historically, Futures Contracts and Other Crude Oil-Related Investments have generally been non-correlated to the performance of other asset classes such as stocks and bonds. Non-correlation means that there is a low statistically valid relationship between the performance of futures and other commodity interest transactions, on the one hand, and stocks or bonds, on the other hand. However, there can be no assurance that such non-correlation will continue during future periods. If, contrary to historic patterns, USBO’s performance were to move in the same general direction as the financial markets, investors will obtain little or no diversification benefits from an investment in the units. In such a case, USBO may have no gains to offset losses from other investments, and investors may suffer losses on their investment in USBO at the same time they incur losses with respect to other investments.

11

Variables such as drought, floods, weather, embargoes, tariffs and other political events may have a larger impact on crude oil prices and crude oil-linked instruments, including Futures Contracts and Other Crude Oil-Related Investments, than on traditional securities. These additional variables may create additional investment risks that subject USBO’s investments to greater volatility than investments in traditional securities.

Non-correlation should not be confused with negative correlation, where the performance of two asset classes would be opposite of each other. There is no historic evidence that the spot price of crude oil and prices of other financial assets, such as stocks and bonds, are negatively correlated. In the absence of negative correlation, USBO cannot be expected to be automatically profitable during unfavorable periods for the stock market, or vice versa.

USBO’s Operating Risks

USBO is not a registered investment company so unitholders do not have the protections of the 1940 Act.

USBO is not an investment company subject to the 1940 Act. Accordingly, investors do not have the protections afforded by that statute which, for example, requires investment companies to have a majority of disinterested directors and regulates the relationship between the investment company and its investment manager.

The General Partner is leanly staffed and relies heavily on key personnel to manage trading activities.

In managing and directing the day-to-day activities and affairs of USBO, the General Partner relies heavily on Messrs. Howard Mah and John Hyland. If Messrs. Mah or Hyland were to leave or be unable to carry out their present responsibilities, it may have an adverse effect on the management of USBO. Furthermore, Messrs. Mah and Hyland are currently involved in the management of the Related Public Funds. The General Partner has also filed registration statements to register units of United States Sugar Fund (“USSF”), United States Natural Gas Double Inverse Fund (“UNGD”), United States Gasoil Fund (“USGO”) and UAC, each a series of the United States Commodity Funds Trust I, and US Golden Currency Fund (“HARD”), a series of the United States Currency Funds Trust. Mr. Mah is also employed by Ameristock Corporation, a registered investment adviser that until January 11, 2013 managed a public mutual fund. On January 11, 2013, Ameristock Mutual Fund, Inc. merged with and into the Drexel Hamilton Centre American Equity Fund, a series of the Drexel Hamilton Mutual Funds. Drexel Hamilton Mutual Funds and its advisor, Drexel Hamilton Investment Partners, are not affiliated with Ameristock Corporation, the Ameristock Mutual Fund Inc., or the General Partner. After the consummation of the reorganization and liquidation, the Ameristock Corporation maintained its non-advisory assets. It is estimated that Mr. Mah will spend approximately 98% of his time on USBO and Related Public Fund matters. Mr. Hyland will spend approximately 100% of his time on USBO and Related Public Fund matters. To the extent that the General Partner establishes additional funds, even greater demands will be placed on Messrs. Mah and Hyland, as well as the other officers of the General Partner and its Board.

Accountability levels, position limits, and daily price fluctuation limits set by the exchanges have the potential to cause a tracking error, which could cause the price of units to substantially vary from the price of the Benchmark Futures Contract and prevent investors from being able to effectively use USBO as a way to hedge against crude oil-related losses or as a way to indirectly invest in crude oil.

Designated contract markets such as the NYMEX and ICE Futures have established accountability levels and position limits on the maximum net long or net short futures contracts in commodity interests that any person or group of persons under common trading control (other than as a hedge, which an investment by USBO is not) may hold, own or control. In addition to accountability levels and position limits, the NYMEX and ICE Futures also set daily price fluctuation limits on futures contracts. The daily price fluctuation limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price. Once the daily price fluctuation limit has been reached in a particular futures contract, no trades may be made at a price beyond that limit.

In late 2011, the CFTC adopted rules that impose new position limits on Referenced Contracts involving 28 energy, metals and agricultural commodities (the “Position Limit Rules”). The Position Limit Rules were scheduled to become effective on October 12, 2012. However, on September 28, 2012, the United States District Court for the District of Columbia vacated these regulations on the basis of ambiguities in the provisions of the CEA (as modified by the Dodd-Frank Act) upon which the regulations were based. In its September 28th decision, the court remanded the Position Limit Rules to the CFTC with instructions to use its expertise and experience to resolve the ambiguities in the statute. On November 15, 2012, the CFTC indicated that it will move forward with an appeal of the District Court’s decision to vacate the Position Limit Rules. At this time, it is not possible to predict how the CFTC’s appeal could affect USBO, but it may be substantial and adverse. Furthermore, until such time as the appeal is resolved or, if applicable revisions to the Position Limit Rules are proposed and adopted, the regulatory architecture in effect prior to the enactment of the Position Limit Rules will govern transactions in commodities and related derivatives. Under that system, the CFTC enforces federal limits on speculation in agricultural products (e.g., corn, wheat and soy), while futures exchanges enforce accountability levels for agricultural and certain energy products (e.g., oil and natural gas). As a result, USBO may be limited with respect to the size of its investments in any commodities subject to these limits. Finally, subject to certain narrow exceptions, the vacated Position Limit Rules would have required the aggregation, for purposes of the position limits, of all positions in the 28 Referenced Contracts held by a single entity and its affiliates, regardless of whether such position existed on U.S. futures exchanges, non-U.S. futures exchanges, in cleared swaps or in over-the-counter swaps. The CFTC is presently considering new aggregation rules, under a rulemaking proposal that is distinct from the Position Limit Rules. At this time, it is unclear how any modified aggregation rules may affect USBO, but it may be substantial and adverse. By way of example, the aggregation rules in combination with any potential revised Position Limit Rules may negatively impact the ability of USBO to meet its investment objectives through limits that may inhibit the General Partner’s ability to sell additional Creation Baskets of USBO.

All of these limits may potentially cause a tracking error between the price of the units and the price of the Benchmark Futures Contract. This may in turn prevent investors from being able to effectively use USBO as a way to hedge against crude oil-related losses or as a way to indirectly invest in crude oil.

USBO has not limited the size of its offering and is committed to utilizing substantially all of its proceeds to purchase Futures Contracts and Other Crude Oil-Related Investments. If USBO is required to limit or reduce the size of its positions in Brent crude oil contracts on the NYMEX or ICE Futures, it may then, if permitted under applicable regulatory requirements, purchase Futures Contracts on other exchanges that trade listed crude oil futures. In addition, if USBO exceeds accountability levels on either the NYMEX or ICE Futures and is required by such exchanges to reduce its holdings, such reduction could potentially cause a tracking error between the price of the units and the price of the Benchmark Futures Contract.

To the extent that the General Partner uses spreads and straddles as part of its trading strategy, there is the risk that the per unit NAV may not closely track the changes in the Benchmark Futures Contract.

If the General Partner were to utilize a spread or straddle position and the spread performed differently than expected, the results could impact USBO’s tracking error. This could affect USBO’s investment objective of having its per unit NAV closely track the changes in the Benchmark Futures Contract. Additionally, a loss on a spread position would negatively impact USBO’s absolute return.

USBO and the General Partner may have conflicts of interest, which may permit them to favor their own interests to the detriment of unitholders.

USBO and the General Partner may have inherent conflicts to the extent the General Partner attempts to maintain USBO’s asset size in order to preserve its fee income and this may not always be consistent with USBO’s objective of having the value of its units’ per unit NAV track the changes in the Benchmark Futures Contract. The General Partner’s officers, directors and employees do not devote their time exclusively to USBO.  These persons are directors, officers or employees of other entities that may compete with USBO for their services. They could have a conflict between their responsibilities to USBO and to those other entities.

In addition, the General Partner’s principals, officers, directors or employees may trade futures and related contracts for their own account. A conflict of interest may exist if their trades are in the same markets and at the same time as USBO trades using the clearing broker to be used by USBO.  A potential conflict also may occur if the General Partner’s principals, officers, directors or employees trade their accounts more aggressively or take positions in their accounts which are opposite, or ahead of, the positions taken by USBO.

The General Partner has sole current authority to manage the investments and operations of USBO, and this may allow it to act in a way that furthers its own interests which may create a conflict with the best interests of investors. Limited partners have limited voting control, which will limit the ability to influence matters such as amendment of the LP Agreement, change in USBO’s basic investment policy, dissolution of this fund, or the sale or distribution of USBO’s assets.

The General Partner serves as the general partner to each of USBO, USOF, USNG, US12OF, UGA, USDHO, USSO and US12NG and the sponsor for USCI, CPER, USAG and USMI and will serve as the sponsor for USSF, UNGD, USGO, UAC and HARD if such funds offer their securities to the public or begin operations. The General Partner may have a conflict to the extent that its trading decisions for USBO may be influenced by the effect they would have on the other funds it manages.  These trading decisions may be influenced since the General Partner also serves as the general partner or sponsor for all of the funds and is required to meet all of the funds’ investment objectives as well as USBO’s. If the General Partner believes that a trading decision it made on behalf of USBO might (i) impede its other funds from reaching their investment objectives, or (ii) improve the likelihood of meeting its other funds’ objectives, then the General Partner may choose to change its trading decision for USBO, which could either impede or improve the opportunity for USBO to meet its investment objective. In addition, the General Partner is required to indemnify the officers and directors of its other funds if the need for indemnification arises. This potential indemnification will cause the General Partner’s assets to decrease.  If the General Partner’s other sources of income are not sufficient to compensate for the indemnification, then the General Partner may terminate and investors could lose their investment.

13

Unitholders may only vote on the removal of the General Partner and limited partners have only limited voting rights. Unitholders and limited partners will not participate in the management of USBO and do not control the General Partner so they will not have influence over basic matters that affect USBO. In addition, USBO could terminate at any time and cause the liquidation and potential loss of an investor’s investment and could upset the overall maturity and timing of an investor’s investment portfolio.

Limited partners will have limited voting rights with respect to USBO’s affairs. Unitholders must apply to become limited partners, and unitholders that have not applied to become limited partners have no voting rights, other than to remove the General Partner as the general partner of USBO. Even then, unitholders may remove the General Partner only if 66 2/3% of the unitholders elect to do so. Unitholders and limited partners will not be permitted to participate in the management or control of USBO or the conduct of its business. Unitholders and limited partners must therefore rely upon the duties and judgment of the General Partner to manage USBO’s affairs.

USBO may terminate at any time, regardless of whether USBO has incurred losses, subject to the terms of the LP Agreement. In particular, unforeseen circumstances, including the death, adjudication of incompetence, bankruptcy, dissolution, or removal of the General Partner as the general partner of USBO could cause USBO to terminate unless a majority interest of the limited partners within 90 days of the event elects to continue the partnership and appoints a successor general partner, or the affirmative vote of a majority in interest of the limited partners subject to certain conditions. However, no level of losses will require the General Partner to terminate USBO. USBO’s termination would cause the liquidation and potential loss of an investor’s investment. Termination could also negatively affect the overall maturity and timing of an investor’s investment portfolio.

The General Partner may manage a large amount of assets and this could affect USBO’s ability to trade profitably.

Increases in assets under management may affect trading decisions. In general, the General Partner does not intend to limit the amount of assets of USBO that it may manage. The more assets the General Partner manages, the more difficult it may be for it to trade profitably because of the difficulty of trading larger positions without adversely affecting prices and performance and of managing risk associated with larger positions.

Limited partners may have limited liability in certain circumstances, including potentially having liability for the return of wrongful distributions.

Under Delaware law, a limited partner might be held liable for USBO’s obligations as if it were a general partner if the limited partner participates in the control of the partnership’s business and the persons who transact business with the partnership think the limited partner is the general partner.

A limited partner will not be liable for assessments in addition to its initial capital investment in any of USBO’s capital securities representing units. However, a limited partner may be required to repay to USBO any amounts wrongfully returned or distributed to it under some circumstances. Under Delaware law, USBO may not make a distribution to limited partners if the distribution causes USBO’s liabilities (other than liabilities to partners on account of their partnership interests and nonrecourse liabilities) to exceed the fair value of USBO’s assets. Delaware law provides that a limited partner who receives such a distribution and knew at the time of the distribution that the distribution violated the law will be liable to the limited partnership for the amount of the distribution for three years from the date of the distribution.

With adequate notice, a limited partner may be required to withdraw from the partnership for any reason.

If the General Partner gives at least fifteen (15) days’ written notice to a limited partner, then the General Partner may for any reason, in its sole discretion, require any such limited partner to withdraw entirely from the partnership or to withdraw a portion of its partner capital account. The General Partner may require withdrawal even in situations where the limited partner has complied completely with the provisions of the LP Agreement.

USBO does not expect to make cash distributions.

USBO has not previously made any cash distributions and intends to re-invest any realized gains in additional Crude Oil Interests rather than distributing cash to limited partners. Therefore, unlike mutual funds, commodity pools or other investment pools that actively manage their investments in an attempt to realize income and gains from their investing activities and distribute such income and gains to their investors, USBO generally does not expect to distribute cash to limited partners. An investor should not invest in USBO if it will need cash distributions from USBO to pay taxes on its share of income and gains of USBO, if any, or for any other reason. Although USBO does not intend to make cash distributions, the income earned from its investments held directly or posted as margin may reach levels that merit distribution, e.g., at levels where such income is not necessary to support its underlying investments in Crude Oil Interests and investors adversely react to being taxed on such income without receiving distributions that could be used to pay such tax. If this income becomes significant then cash distributions may be made.

14

There is a risk that USBO will not earn trading gains sufficient to compensate for the fees and expenses that it must pay and as such USBO may not earn any profit.

USBO pays brokerage charges of approximately 0.06% of average total net assets based on futures commission merchant fees of $3.50 per buy or sell, management fees of 0.75% of NAV on its average daily net assets, and over-the-counter spreads and extraordinary expenses (e.g., subsequent offering expenses, other expenses not in the ordinary course of business, including the indemnification of any person against liabilities and obligations to the extent permitted by law and required under the LP Agreement and under agreements entered into by the General Partner on USBO’s behalf and the bringing and defending of actions at law or in equity and otherwise engaging in the conduct of litigation and the incurring of legal expenses and the settlement of claims and litigation) that cannot be quantified.

These fees and expenses must be paid in all cases regardless of whether USBO’s activities are profitable. Accordingly, USBO must earn trading gains sufficient to compensate for these fees and expenses before it can earn any profit.

If offerings of the units do not raise sufficient funds to pay USBO’s future expenses and no other source of funding of expenses is found, USBO may be forced to terminate and investors may lose all or part of their investment.

Prior to the offering of units that commenced on June 2, 2010, all of USBO’s expenses were funded by the General Partner and its affiliates. These payments by the General Partner and its affiliates were designed to allow USBO the ability to commence the public offering of its units. USBO now directly pays certain of these fees and expenses. The General Partner will continue to pay other fees and expenses, as set forth in the LP Agreement. If the General Partner and USBO are unable to raise sufficient funds to cover their expenses or locate any other source of funding, USBO may be forced to terminate and investors may lose all or part of their investment.

USBO may incur higher fees and expenses upon renewing existing or entering into new contractual relationships.

The clearing arrangements between the clearing brokers and USBO generally are terminable by the clearing brokers once the clearing broker has given USBO notice. Upon termination, the General Partner may be required to renegotiate or make other arrangements for obtaining similar services if USBO intends to continue trading in Futures Contracts or Other Crude Oil-Related Investments at its present level of capacity. The services of any clearing broker may not be available, or even if available, these services may not be available on the terms as favorable as those of the expired or terminated clearing arrangements.

USBO may miss certain trading opportunities because it will not receive the benefit of the expertise of independent trading advisors.

The General Partner does not employ trading advisors for USBO; however, it reserves the right to employ them in the future. The only advisor to USBO is the General Partner. A lack of independent trading advisors may be disadvantageous to USBO because it will not receive the benefit of a trading advisor’s expertise.

An unanticipated number of redemption requests during a short period of time could have an adverse effect on the per unit NAV of USBO.

If a substantial number of requests for redemption of Redemption Baskets are received by USBO during a relatively short period of time, USBO may not be able to satisfy the requests from USBO’s assets not committed to trading. As a consequence, it could be necessary to liquidate positions in USBO’s trading positions before the time that the trading strategies would otherwise dictate liquidation.

The financial markets are currently in a period of disruption and USBO does not expect these conditions to improve in the near future.

Since 2008, the financial markets have experienced very difficult conditions and volatility as well as significant adverse trends. The conditions in these markets have resulted in a decrease in availability of corporate credit and liquidity and have led indirectly to the insolvency, closure or acquisition of a number of major financial institutions and have contributed to further consolidation within the financial services industry. In addition, the Administration and Congress have periodically been reaching impasses in passing a fiscal budget, which could create long-term concerns regarding the credit of the United States and interest earned, as well as the United States Government’s ability to pay its obligations to holders of Treasuries. If low interest rates on Treasuries continues or if USBO is not able to redeem its investments in Treasuries prior to maturity and the U.S. Government cannot pay its obligations, USBO would be negatively impacted. In addition, USBO might also be negatively impacted by its use of money market mutual funds to the extent those funds might themselves be using Treasuries. Although the financial markets saw signs of recovery beginning in late 2010 and 2011, economic growth in 2012 was slow and the financial markets are still fragile. A poor financial recovery could adversely affect the financial condition and results of operations of USOF’s service providers and Authorized Purchasers, which would impact the ability of the General Partner to achieve USBO’s investment objective.

15

The failure or bankruptcy of a clearing broker or USBO’s Custodian could result in a substantial loss of USBO’s assets and could impair USBO in its ability to execute trades.

Under CFTC regulations, a clearing broker maintains customers’ assets in a bulk segregated account. If a clearing broker fails to do so, or even if the customers’ funds are segregated by the clearing broker but the clearing broker is unable to satisfy a substantial deficit in a customer account, the clearing broker’s other customers may be subject to risk of a substantial loss of their funds in the event of that clearing broker’s bankruptcy. In that event, the clearing broker’s customers, such as USBO, are entitled to recover, even in respect of property specifically traceable to them, only a proportional share of all property available for distribution to all of that clearing broker’s customers. The bankruptcy of a clearing broker could result in the complete loss of USBO’s assets posted with the clearing broker; though the vast majority of USBO’s assets are held in Treasuries, cash and/or cash equivalents with the Custodian and would not be impacted by the bankruptcy of a clearing broker. USBO also may be subject to the risk of the failure of, or delay in performance by, any exchanges and markets and their clearing organizations, if any, on which commodity interest contracts are traded.

In addition, to the extent USBO’s clearing broker is required to post USBO’s assets as margin to a clearinghouse, the margin will be maintained in an omnibus account containing the margin of all of the clearing broker’s customers. If USBO’s clearing broker defaults to a clearinghouse because of a default by one of the clearing broker’s other customers or otherwise, then the clearinghouse can look to all of the margin in the omnibus account, including margin posted by USBO and any other non-defaulting customers of the clearing broker to satisfy the obligations of the clearing broker.

From time to time, the clearing brokers may be subject to legal or regulatory proceedings in the ordinary course of their business. A clearing broker’s involvement in costly or time-consuming legal proceedings may divert financial resources or personnel away from the clearing broker’s trading operations, which could impair the clearing broker’s ability to successfully execute and clear USBO’s trades.

In addition, the majority of USBO’s assets are held in Treasuries, cash and/or cash equivalents with the Custodian. The insolvency of the Custodian could result in a complete loss of USBO’s assets held by that Custodian, which, at any given time, would likely comprise a substantial portion of USBO’s total assets.

Third parties may infringe upon or otherwise violate intellectual property rights or assert that the General Partner has infringed or otherwise violated their intellectual property rights, which may result in significant costs and diverted attention.

Third parties may utilize USBO’s intellectual property or technology, including the use of its business methods, trademarks and trading program software, without permission. The General Partner has a patent for USBO’s business method and it has registered its trademarks. USBO does not currently have any proprietary software. However, if it obtains proprietary software in the future, then any unauthorized use of USBO’s proprietary software and other technology could also adversely affect its competitive advantage. USBO may not have adequate resources to implement procedures for monitoring unauthorized uses of its patents, trademarks, proprietary software and other technology. Also, third parties may independently develop business methods, trademarks or proprietary software and other technology similar to that of the General Partner or claim that the General Partner has violated their intellectual property rights, including their copyrights, trademark rights, trade names, trade secrets and patent rights. As a result, the General Partner may have to litigate in the future to protect its trade secrets, determine the validity and scope of other parties’ proprietary rights, defend itself against claims that it has infringed or otherwise violated other parties’ rights, or defend itself against claims that its rights are invalid. Any litigation of this type, even if the General Partner is successful and regardless of the merits, may result in significant costs, divert its resources from USBO, or require it to change its proprietary software and other technology or enter into royalty or licensing agreements.

The success of USBO depends on the ability of the General Partner to accurately implement trading systems, and any failure to do so could subject USBO to losses on such transactions.

The General Partner uses mathematical formulas built into a generally available spreadsheet program to decide whether it should buy or sell Crude Oil Interests each day. Specifically, The General Partner uses the spreadsheet to make mathematical calculations and to monitor positions in Crude Oil Interests and Treasuries and correlations to the Benchmark Futures Contract. The General Partner must accurately process the spreadsheets’ outputs and execute the transactions called for by the formulas. In addition, USBO relies on the General Partner to properly operate and maintain its computer and communications systems.

Extraordinary transaction volume, hardware or software failure, power or telecommunications failure, a natural disaster or other catastrophe could cause the computer systems to operate at an unacceptably slow speed or even fail. Any significant degradation or failure of the systems that the General Partner uses to gather and analyze information, enter orders, process data, monitor risk levels and otherwise engage in trading activities may result in substantial losses on transactions, liability to other parties, lost profit opportunities, damages to the General Partner’s and USBO’s reputations, increased operational expenses and diversion of technical resources. Any failure, inaccuracy or delay in implementing any of the formulas or systems, including implementing upgrades and compatibility with the computer systems of third parties, and executing USBO’s transactions could impair its ability to achieve USBO’s investment objective. It could also result in decisions to undertake transactions based on inaccurate or incomplete information. This could cause substantial losses on transactions.

16

The occurrence of a terrorist attack, or the outbreak, continuation or expansion of war or other hostilities could disrupt USBO’s trading activity and materially affect USBO’s profitability.

The operations of USBO, the exchanges, brokers and counterparties with which USBO does business, and the markets in which USBO does business could be severely disrupted in the event of a major terrorist attack or the outbreak, continuation or expansion of war or other hostilities. Global anti-terrorism initiatives, political unrest in the Middle East and Southeast Asia, as well as political hostility towards the United States, continue to fuel this concern.

Risk of Leverage and Volatility

If the General Partner permits USBO to become leveraged, investors could lose all or substantially all of their investment if USBO’s trading positions suddenly turn unprofitable.

Commodity pools’ trading positions in futures contracts or other commodity interests are typically required to be secured by the deposit of margin funds that represent only a small percentage of a futures contract’s (or other commodity interests’) entire market value. This feature permits commodity pools to “leverage” their assets by purchasing or selling futures contracts (or other commodity interests) with an aggregate value in excess of the commodity pool’s assets. While this leverage can increase the pool’s profits, relatively small adverse movements in the price of the pool’s futures contracts can cause significant losses to the pool. While the General Partner has not and does not currently intend to leverage USBO’s assets, it is not prohibited from doing so under the LP Agreement or otherwise.

The price of crude oil is volatile which could cause large fluctuations in the price of units.

Movements in the price of crude oil may be the result of factors outside of the General Partner’s control and may not be anticipated by the General Partner. Among the factors that can cause volatility in the price of crude oil are:

• worldwide or regional demand for energy, which is affected by economic conditions;

• the domestic and foreign supply and inventories of oil and gas;

• weather conditions, including abnormally mild winter or summer weather, and abnormally harsh winter or summer weather;

• availability and adequacy of pipeline and other transportation facilities;

• availability of storage facilities;

• domestic and foreign governmental regulations and taxes;

• political conditions in gas or oil producing regions;

• technological advances relating to energy usage or relating to technology for exploration, production, refining and petrochemical manufacturing;

• the ability of members of the Organization of the Petroleum Exporting Countries (“OPEC”) to agree upon and maintain oil prices and production levels;

• the price and availability of alternative fuels;

• the impact of energy conservation efforts; and

• the impact of environmental and other government regulations.

17

Over-the-Counter Contract Risk

Currently, over-the-counter transactions are subject to little regulation.

A portion of USBO’s assets may be used to trade over-the-counter contracts, such as forward contracts or swap or spot contracts. Currently, over-the-counter contracts are typically contracts traded on a principal-to-principal, non-cleared basis through dealer markets that are dominated by major money center and investment banks and other institutions and that prior to the passage of the Dodd-Frank Act had been essentially unregulated by the CFTC. The markets for over-the-counter contracts have relied upon the integrity of market participants in lieu of the additional regulation imposed by the CFTC on participants in the futures markets. To date, the forward markets have been largely unregulated, forward contracts have been executed bi-laterally and, in general, forward contracts have not been cleared or guaranteed by a third party. On November 16, 2012, the Secretary of the Treasury issued a final determination that exempts both foreign exchange swaps and foreign exchange forwards from the definition of “swap” and, by extension, additional regulatory requirements (such as clearing and margin). The final determination does not extend to other foreign exchange derivatives, such as foreign exchange options, currency swaps, and non-deliverable forwards. While the Dodd-Frank Act and certain regulations adopted thereunder are intended to provide additional protections to participants in the over-the-counter market, the current regulation of the over-the-counter contracts could expose USBO in certain circumstances to significant losses in the event of trading abuses or financial failure by participants. On November 28, 2012, the CFTC issued its final clearing determination requiring that certain credit default swaps and interest rate swaps be cleared by registered DCOs. This is the CFTC’s first clearing determination under the Dodd-Frank Act and became effective on February 13, 2013. Determination on other types of swaps are expected in the future, and, when finalized, could require USBO to centrally clear certain over-the-counter instruments presented entered into and settled on a bi-lateral basis. See “Regulation” on page 5 of the Statement of Additional Information for a discussion of how the over-the-counter market will be subject to much more extensive CFTC oversight and regulation after the implementation of the Dodd-Frank Act.

USBO will be subject to credit risk with respect to counterparties to over-the-counter contracts entered into by USBO or held by special purpose or structured vehicles.

USBO faces the risk of non-performance by the counterparties to the over-the-counter contracts. Unlike in futures contracts, the counterparty to these contracts is generally a single bank or other financial institution, rather than a clearing organization backed by a group of financial institutions. As a result, there will be greater counterparty credit risk in these transactions. A counterparty may not be able to meet its obligations to USBO, in which case USBO could suffer significant losses on these contracts.

If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, USBO may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. USBO may obtain only limited recovery or may obtain no recovery in such circumstances.

USBO may be subject to liquidity risk with respect to its over-the-counter contracts.

Over-the-counter contracts are less marketable because they are not traded on an exchange, do not have uniform terms and conditions, and are entered into based upon the creditworthiness of the parties and the availability of credit support, such as collateral, and in general, they are not transferable without the consent of the counterparty.  These conditions make such contracts less liquid than standardized futures contracts traded on a commodities exchange and could adversely impact USBO’s ability to realize the full value of such contracts.  In addition, even if collateral is used to reduce counterparty credit risk, sudden changes in the value of over-the-counter transactions may leave a party open to financial risk due to a counterparty default since the collateral held may not cover a party’s exposure on the transaction in such situations.

In general, valuing over-the-counter derivatives is less certain than valuing actively traded financial instruments such as exchange traded futures contracts and securities or cleared swaps because the price and terms on which such over-the-counter derivatives are entered into or can be terminated are individually negotiated, and those prices and terms may not reflect the best price or terms available from other sources. In addition, while market makers and dealers generally quote indicative prices or terms for entering into or terminating over-the-counter contracts, they typically are not contractually obligated to do so, particularly if they are not a party to the transaction. As a result, it may be difficult to obtain an independent value for an outstanding over-the-counter derivatives transaction.

The Dodd-Frank Act requires the CFTC and SEC to establish “both initial and variation margin requirements on all swaps that are not cleared by a registered clearing organization” (i.e., uncleared swaps). In addition, the Dodd-Frank Act provides parties who post initial margin to a swap dealer or major swap participant with a statutory right to insist that such margin be held in a segregated account with an independent custodian. At this time, the CFTC has proposed a rule addressing this statutory right of certain market participants but has not yet implemented any final rules. On November 16, 2012, the Secretary of the Treasury issued a final determination that exempts both foreign exchange swaps and foreign exchange forwards from the definition of “swap” and, by extension, additional regulatory requirements (such as clearing and margin).

Risk of Trading in International Markets

Trading in international markets could expose USBO to credit and regulatory risk.

USBO invests primarily in Futures Contracts, a significant portion of which are traded on exchanges outside the United States, including the ICE Futures. Some non-U.S. markets present risks because they are not subject to the same degree of regulation as their U.S. counterparts. The CFTC, NFA and the domestic exchanges have little, if any, regulatory authority over the activities of any foreign boards of trade or exchanges, including the execution, delivery and clearing of transactions, and have little, if any, power to compel enforcement of the rules of a foreign board of trade or exchange or of any applicable non-U.S. laws.

Similarly, the rights of market participants, such as USBO, in the event of the insolvency or bankruptcy of a non-U.S. market or broker are also likely to be more limited than in the case of U.S. markets or brokers. As a result, in these markets, USBO has less legal and regulatory protection than it does when it trades domestically.

18

In some of these non-U.S. markets, the performance on a contract is the responsibility of the counterparty and is not backed by an exchange or clearing corporation and therefore exposes USBO to credit risk. However, Futures Contracts traded on the ICE Futures, including the Benchmark Futures Contract, are backed by the ICE Futures and may not expose USBO to the risks of some other non-U.S. exchanges or clearing corporations that do not have similar backing. Trading in non-U.S. markets also leaves USBO susceptible to swings in the value of the local currency against the U.S. dollar. The Benchmark Futures Contract, however, is traded in U.S. dollars and does not expose USBO to the risk of currency fluctuations. Additionally, trading on non-U.S. exchanges is subject to the risks presented by exchange controls, expropriation, increased tax burdens and exposure to local economic declines and political instability. An adverse development with respect to any of these variables could reduce the profit or increase the loss earned on trades in the affected international markets.

International trading activities subject USBO to foreign exchange risk.

The price of any non-U.S. commodity interest and, therefore, the potential profit and loss on such investment, may be affected by any variance in the foreign exchange rate between the time the order is placed and the time it is liquidated, offset or exercised. As a result, changes in the value of the local currency relative to the U.S. dollar may cause losses to USBO even if the contract traded is profitable.

USBO’s international trading could expose it to losses resulting from non-U.S. exchanges that are less developed or less reliable than United States exchanges.

Some non-U.S. exchanges may be in a more developmental stage so that prior price histories may not be indicative of current price dynamics. In addition, USBO may not have the same access to certain positions on foreign trading exchanges as do local traders, and the historical market data on which the General Partner bases its strategies may not be as reliable or accessible as it is for U.S. exchanges.

Tax Risk

An investor’s tax liability may exceed the amount of distributions, if any, on its units.

Cash or property will be distributed at the sole discretion of the General Partner. The General Partner has not and does not currently intend to make cash or other distributions with respect to units. Investors will be required to pay U.S. federal income tax and, in some cases, state, local, or foreign income tax, on their allocable share of USBO’s taxable income, without regard to whether they receive distributions or the amount of any distributions. Therefore, the tax liability of an investor with respect to its units may exceed the amount of cash or value of property (if any) distributed.

An investor’s allocable share of taxable income or loss may differ from its economic income or loss on its units.

Due to the application of the assumptions and conventions applied by USBO in making allocations for tax purposes and other factors, an investor’s allocable share of USBO’s income, gain, deduction or loss may be different than its economic profit or loss from its units for a taxable year. This difference could be temporary or permanent and, if permanent, could result in it being taxed on amounts in excess of its economic income.

Items of income, gain, deduction, loss and credit with respect to units could be reallocated if the IRS does not accept the assumptions and conventions applied by USBO in allocating those items, with potential adverse consequences for an investor.

The U.S. tax rules pertaining to partnerships are complex and their application to large, publicly traded partnerships such as USBO is in many respects uncertain. USBO applies certain assumptions and conventions in an attempt to comply with the intent of the applicable rules and to report taxable income, gains, deductions, losses and credits in a manner that properly reflects unitholders’ economic gains and losses. These assumptions and conventions may not fully comply with all aspects of the Internal Revenue Code (the “Code”) and applicable Treasury Regulations, however, and it is possible that the U.S. Internal Revenue Service will successfully challenge USBO’s allocation methods and require USBO to reallocate items of income, gain, deduction, loss or credit in a manner that adversely affects investors. If this occurs, investors may be required to file an amended tax return and to pay additional taxes plus deficiency interest.

USBO could be treated as a corporation for federal income tax purposes, which may substantially reduce the value of the units.

USBO has received an opinion of counsel that, under current U.S. federal income tax laws, USBO will be treated as a partnership that is not taxable as a corporation for U.S. federal income tax purposes, provided that (i) at least 90 percent of USBO’s annual gross income consists of “qualifying income” as defined in the Code, (ii) USBO is organized and operated in accordance with its governing agreements and applicable law and (iii) USBO does not elect to be taxed as a corporation for federal income tax purposes. Although the General Partner anticipates that USBO has satisfied and will continue to satisfy the “qualifying income” requirement for all of its taxable years, that result cannot be assured. USBO has not requested and will not request any ruling from the IRS with respect to its classification as a partnership not taxable as a corporation for federal income tax purposes. If the IRS were to successfully assert that USBO is taxable as a corporation for federal income tax purposes in any taxable year, rather than passing through its income, gains, losses and deductions proportionately to unitholders, USBO would be subject to tax on its net income for the year at corporate tax rates. In addition, although the General Partner does not currently intend to make distributions with respect to units, any distributions would be taxable to unitholders as dividend income. Taxation of USBO as a corporation could materially reduce the after-tax return on an investment in units and could substantially reduce the value of the units.

19

USBO is organized and operated as a limited partnership in accordance with the provisions of the LP Agreement and applicable state law, and therefore, USBO has a more complex tax treatment than traditional mutual funds.

USBO is organized and operated as a limited partnership in accordance with the provisions of the LP Agreement and applicable state law. No U.S. federal income tax is paid by USBO on its income. Instead, USBO will furnish unitholders each year with tax information on IRS Schedule K-1 (Form 1065) and each U.S. unitholder is required to report on its U.S. federal income tax return its allocable share of the income, gain, loss and deduction of USBO. This must be reported without regard to the amount (if any) of cash or property the unitholder receives as a distribution from USBO during the taxable year. A unitholder, therefore, may be allocated income or gain by USBO but receive no cash distribution with which to pay the tax liability resulting from the allocation, or may receive a distribution that is insufficient to pay such liability.

In addition to federal income taxes, unitholders may be subject to other taxes, such as state and local income taxes, unincorporated business taxes, business franchise taxes and estate, inheritance or intangible taxes that may be imposed by the various jurisdictions in which USBO does business or owns property or where the unitholders reside. Although an analysis of those various taxes is not presented here, each prospective unitholder should consider their potential impact on its investment in USBO. It is each unitholder’s responsibility to file the appropriate U.S. federal, state, local and foreign tax returns.

PROSPECTIVE INVESTORS ARE STRONGLY URGED TO CONSULT THEIR OWN TAX ADVISOR WITH RESPECT TO THE POSSIBLE TAX CONSEQUENCES TO THEM OF AN INVESTMENT IN UNITS; SUCH TAX CONSEQUENCES MAY DIFFER IN RESPECT TO DIFFERENT INVESTORS.

THE OFFERING

What is USBO?

USBO is a Delaware limited partnership organized on September 2, 2009. USBO maintains its main business office at 1999 Harrison Street, Suite 1530, Oakland, California 94612. USBO is a commodity pool that issues limited partnership interests (“units”) traded on the NYSE Arca, Inc. (the “NYSE Arca”). It operates pursuant to the terms of the LP Agreement, which grants full management control to the General Partner.

USBO is a publicly traded limited partnership which seeks to have the daily changes in percentage terms of its units’ NAV track the daily changes in percentage terms of the spot price of Brent crude oil, as measured by the daily changes in the price of the futures contract for Brent crude oil traded on the ICE Futures Exchange, less USBO’s expenses. The General Partner does not intend to operate USBO in a fashion such that its per unit NAV will equal, in dollar terms, the spot price of Brent crude oil or any particular futures contract based on crude oil. It is not the intent of USBO to be operated in a fashion such that its NAV will reflect the percentage change of the price of any particular futures contract as measured over a time period greater than one day. USBO invests in a mixture of listed crude oil futures contracts, other non-listed crude oil related investments, Treasuries, cash and cash equivalents. USBO’s units began trading on the NYSE Arca on June 2, 2010. As of January 31, 2013, USBO had total net assets of $47,334,729 and had outstanding units of 5,500,000.

Who is the General Partner?

Our sole General Partner is United States Commodity Funds LLC, a single member limited liability company that was formed in the state of Delaware on May 10, 2005. Prior to June 13, 2008, the General Partner was known as Victoria Bay Asset Management, LLC. It maintains its main business office at 1999 Harrison Street, Suite 1530, Oakland, California, 94612. The General Partner is a wholly-owned subsidiary of Wainwright Holdings, Inc., a Delaware corporation (“Wainwright”). Mr. Nicholas Gerber (discussed below) controls Wainwright by virtue of his ownership of Wainwright’s shares. Wainwright is a holding company that previously owned an insurance company organized under Bermuda law, which has been liquidated, and a registered investment advisor firm named Ameristock Corporation, which has been distributed to the Wainwright shareholders. The General Partner is a member of the NFA and is registered with the CFTC as of December 1, 2005. The General Partner’s registration as a CPO with the NFA was approved on December 1, 2005.

See “Composite Performance Data for USBO” on page 28. See also “Prior Performance of the General Partner and Related Public Funds” on page 29.

The General Partner is required to evaluate the credit risk of USBO to the futures commission merchant, oversee the purchase and sale of USBO’s units by certain Authorized Purchasers, review daily positions and margin requirements of USBO, and manage USBO’s investments. The General Partner also pays the fees of the Marketing Agent, the Administrator, and the Custodian.

Limited partners have no right to elect the General Partner on an annual or any other continuing basis. If the General Partner voluntarily withdraws, however, the holders of a majority of USBO’s outstanding units (excluding for purposes of such determination units owned, if any, by the withdrawing General Partner and its affiliates) may elect its successor. The General Partner may not be removed as general partner except upon approval by the affirmative vote of the holders of at least 66 2/3% of our outstanding units (excluding units owned, if any, by the General Partner and its affiliates), subject to the satisfaction of certain conditions set forth in the LP Agreement.

The business and affairs of our General Partner are managed by a board of directors (the “Board”), which is comprised of three management directors some of whom are also its executive officers (the “Management Directors”), and three independent directors who meet the independent director requirements established by the NYSE Arca Equities Rules and the Sarbanes-Oxley Act of 2002. Notwithstanding the foregoing, the Management Directors have the authority to manage the General Partner pursuant to its Limited Liability Company Agreement, as amended from time to time. Through its Management Directors, the General Partner manages the day-to-day operations of USBO. The Board has an audit committee which is made up of the three independent directors (Peter M. Robinson, Gordon L. Ellis, and Malcolm R. Fobes III). The audit committee is governed by an audit committee charter that is posted on USBO’s website. Gordon L. Ellis and Malcolm R. Fobes III meet the financial sophistication requirements of the NYSE Arca and the audit committee charter.

Mr. Nicholas Gerber and Mr. Howard Mah serve as executive officers of the General Partner. USBO has no executive officers. Its affairs are generally managed by the General Partner. The following individuals serve as Management Directors of the General Partner.

	High		Low
Fiscal year 2012
First quarter	$	88.58	$	76.68
Second quarter	$	88.16	$	63.45
Third quarter	$	84.41	$	68.99

Third quarter	$	79.31	$	67.64

Prior Performance of USBO

The General Partner manages USBO, which is a commodity pool that issues units traded on the NYSE Arca. The chart below shows, as of January 31, 2013, the number of Authorized Purchases, the total number of baskets created and redeemed since inception and the number of outstanding units for USBO.

	# of Authorized Purchases		Baskets Purchased		Baskets Redeemed		Outstanding Units
USBO		9		49		47		5,500,000

Since the commencement of the offering of USBO units to the public on June 2, 2010 to January 31, 2013, the simple average daily change in its benchmark futures contract was 0.097%, while the simple average daily change in the NAV of USBO over the same time period was 0.093%. The average daily difference was (0.004)% (or (0.4) basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the benchmark futures contract, the average error in daily tracking by the NAV was (0.883)%, meaning that over this time period USBO’s tracking error was within the plus or minus 10% range established as its benchmark tracking goal.

The table below shows the relationship between the trading prices of the units and the daily NAV of USBO, since inception through January 31, 2013. The first row shows the average amount of the variation between USBO’s closing market price and NAV, computed on a daily basis since inception, while the second and third rows depict the maximum daily amount of the end of day premiums and discounts to NAV since inception, on a percentage basis. The General Partner believes that maximum and minimum end of day premiums and discounts typically occur because trading in the units continues on the NYSE Arca until 4:00 p.m. New York time while regular trading in the Benchmark Component Futures Contracts on the Futures Exchanges ceases at 2:30 p.m. New York time and the value of the Benchmark Component Futures Contracts, for purposes of determining its end of day NAV, can be determined at that time. The information for the Related Public Funds may be found on page 30.

*** Through January 31, 2013

Draw-down: Losses experienced over a specified period. Draw-down is measured on the basis of monthly returns only and does not reflect intra-month figures.

Worst Monthly Percentage Draw-down: The largest single month loss sustained since inception of trading.

Worst Peak-to-Valley Draw-down: The largest percentage decline in the NAV per unit over the history of the fund. This need not be a continuous decline, but can be a series of positive and negative returns where the negative returns are larger than the positive returns. Worst Peak-to-Valley Draw-down represents the greatest percentage decline from any month-end NAV per unit that occurs without such month-end NAV per unit being equaled or exceeded as of a subsequent month-end. For example, if the NAV per unit declined by $1 in each of January and February, increased by $1 in March and declined again by $2 in April, a “peak-to-valley drawdown” analysis conducted as of the end of April would consider that “drawdown” to be still continuing and to be $3 in amount, whereas if the NAV per unit had increased by $2 in March, the January-February drawdown would have ended as of the end of February at the $2 level.

The table below shows the relationship between the trading prices of the units of each of the Related Public Funds and the daily NAV of such fund, since inception through January 31, 2013. The first row shows the average amount of the variation between the fund’s closing market price and NAV, computed on a daily basis since inception, while the second and third rows depict the maximum daily amount of the end of day premiums and discounts to NAV since inception, on a percentage basis. The General Partner believes that maximum and minimum end of day premiums and discounts typically occur because trading in units continues on the NYSE Arca until 4:00 p.m. New York time while regular trading in the benchmark futures contract on the NYMEX ceases at 2:30 p.m. New York time and the value of the relevant benchmark futures contract, for purposes of determining its end of day NAV can be determined at that time. One known exception to this conclusion were the premiums on trading in USNG units that occurred between July 8, 2009 and September 28, 2009, when USNG suspended the issuance of Creation Baskets as a result of regulatory concerns relating to the size of USNG’s positions in the natural gas futures and cleared swap markets, and there was continued demand for such units and other similar natural gas futures linked investments in the market.

There are significant differences between investing in the Fund and the Related Public Funds and investing directly in the futures market. The General Partner’s results with USBO and the Related Public Funds may not be representative of results that may be experienced with a fund directly investing in futures contracts or other managed funds investing in futures contracts. Moreover, given the different investment objectives of USBO and the Related Public Funds, the performance of USBO may not be representative of the results that may be experienced by the other Related Public Funds.

Other Related Commodity Trading and Investment Management Experience

Until December 31, 2009, Ameristock Corporation was an affiliate of the General Partner. Ameristock Corporation is a California-based registered investment advisor registered under the Investment Advisors Act of 1940, as amended, that has sponsored and provided portfolio management services to mutual funds from 1995 until January 2013. Ameristock Corporation was the investment adviser to the Ameristock Mutual Fund, Inc., a mutual fund registered under the Investment Company Act of 1940 focused on large cap U.S. equities that, as of December 31, 2012, had $126,879,540 in assets. On January 11, 2013, the Ameristock Mutual Fund, Inc. merged with and into the Drexel Hamilton Centre American Equity Fund, a series of Drexel Hamilton Mutual Funds. Drexel Hamilton Mutual Funds is not affiliated with Ameristock Corporation, the Ameristock Mutual Fund, Inc. or the General Partner.

Ameristock Corporation was also the investment advisor to the Ameristock ETF Trust, an open-end management investment company registered under the 1940 Act that consisted of five separate investment portfolios, each of which sought investment results, before fees and expenses, that corresponded generally to the price and yield performance of a particular U.S. Treasury securities index owned and compiled by Ryan Holdings LLC and Ryan ALM, Inc. The Ameristock ETF Trust has liquidated each of its investment portfolios and has wound up its affairs.

How Does USBO Operate?

The net assets of USBO consist primarily of investments in futures contracts for Brent crude oil, but may also consist of investment contracts for other types of crude oil, natural gas, gasoline, heating oil and other petroleum-based fuels that are traded on the ICE Futures Exchange, NYMEX, or other U.S. and foreign exchanges (such futures contracts are collectively referred to herein as “Futures Contracts”), and to a lesser extent, in order to comply with regulatory requirements or in view of market conditions, other crude oil-related investments such as cash-settled options on Futures Contracts, forward contracts for crude oil, cleared swap contracts and non-exchange traded (“over-the-counter”) transactions that are based on the price of crude oil and other petroleum-based fuels, Futures Contracts and indices based on the foregoing (collectively, “Other Crude Oil-Related Investments”). For convenience and unless otherwise specified, Futures Contracts and Other Crude Oil-Related Investments collectively are referred to as “Crude Oil Interests” in this prospectus. USBO invests substantially the entire amount of its assets in Crude Oil Interests while supporting such investments by holding the amounts of its margin, collateral and other requirements relating to these obligations in Treasuries, cash and cash equivalents. The daily holdings of USBO are available on USBO’s website at www.unitedstatesbrentoilfund.com.

USBO invests in Crude Oil Interests to the fullest extent possible without being leveraged or unable to satisfy its current or potential margin or collateral obligations with respect to its investments in Futures Contracts and Other Crude Oil-Related Investments. The primary focus of the General Partner is the investment in Futures Contracts and the management of USBO’s investments in short-term obligations of the United States of two years or less (“Treasuries”), cash and/or cash equivalents for margining purposes and as collateral.

The investment objective of USBO is for the daily changes in percentage terms of its units’ NAV to reflect the daily changes in percentage terms of the spot price of Brent crude oil as measured by the daily changes in the price of the futures contract on Brent crude oil as traded on the ICE Futures Exchange that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case the futures contract will be the next month contract to expire (the “Benchmark Futures Contract”), less USBO’s expenses. It is not the intent of USBO to be operated in a fashion such that its NAV will equal, in dollar terms, the spot price of crude oil or any particular futures contract based on crude oil. USBO seeks to achieve its investment objective by investing in a combination of Futures Contracts and Other Crude Oil-Related Investments such that the daily changes in its NAV, measured in percentage terms, will closely track the daily changes in the price of the Benchmark Futures Contract, also measured in percentage terms. It is not the intent of USBO to be operated in a fashion such that its NAV will reflect the percentage change of the price of any particular futures contract as measured over a time period greater than one day. The General Partner believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in listed crude oil Futures Contracts and other Crude Oil-Related Investments. USBO may invest in interests other than the Benchmark Futures Contract to comply with accountability levels and position limits. For a detailed discussion of accountability levels and position limits, see “What are Futures Contracts?”.

As a specific benchmark, the General Partner endeavors to place USBO’s trades in Futures Contracts and Other Crude Oil-Related Investments and otherwise manage USBO’s investments so that “A” will be within plus/minus 10 percent of “B”, where:

• A is the average daily change in USBO’s NAV for any period of 30 successive valuation days, i.e. , any NYSE Arca trading day as of which USBO calculates its NAV; and

• B is the average daily change in the price of the Benchmark Futures Contract over the same period.

42

The General Partner believes that market arbitrage opportunities cause daily changes in USBO’s unit price on the NYSE Arca to closely track daily changes in USBO’s NAV per unit. The General Partner further believes that the daily changes in USBO’s NAV in percentage terms closely track the daily changes in percentage terms in the Benchmark Futures Contract, less USBO’s expenses.

43

The following two graphs demonstrate the correlation between the daily changes in the NAV of USBO and the daily changes in the Benchmark Futures Contract both since the initial public offering of USBO’s units on June 2, 2010 through December 31, 2012 and during the last thirty valuation days ended December 31, 2012.

An investment in the units provides a means for diversifying an investor’s portfolio or hedging exposure to changes in Brent crude oil prices. An investment in the units allows both retail and institutional investors to easily gain this exposure to the Brent crude oil market in a transparent, cost-effective manner.

The expected correlation of the price of USBO’s units, USBO’s NAV and the price of the Benchmark Futures Contract is illustrated in the following diagram:

The General Partner employs a “neutral” investment strategy intended to track the changes in the price of the Benchmark Futures Contract regardless of whether the price goes up or goes down. USBO’s “neutral” investment strategy is designed to permit investors generally to purchase and sell USBO’s units for the purpose of investing indirectly in Brent crude oil in a cost-effective manner, and/or to permit participants in the crude oil or other industries to hedge the risk of losses in their Brent crude oil-related transactions. Accordingly, depending on the investment objective of an individual investor, the risks generally associated with taking positions in Brent crude oil and/or the risks involved in hedging may exist. In addition, an investment in USBO involves the risk that the changes in the price of USBO’s units will not accurately track the changes in the price of the Benchmark Futures Contract, and that changes in the Benchmark Futures Contract will not closely correlate with changes in the spot price of Brent crude oil.

45

Term Structure of Brent Crude Oil Futures Prices and the Impact on Total Returns. Several factors determine the total return from investing in a futures contract position. One factor that impacts the total return that will result from investing in near month futures contracts and “rolling” those contracts forward each month is the price relationship between the current near month contract and the next month contract. For example, if the price of the near month contract is higher than the next month contract (a situation referred to as “backwardation” in the futures market), then absent any other change there is a tendency for the price of a next month contract to rise in value as it becomes the near month contract and approaches expiration. Conversely, if the price of a near month contract is lower than the next month contract (a situation referred to as “contango” in the futures market), then absent any other change there is a tendency for the price of a next month contract to decline in value as it becomes the near month contract and approaches expiration.

As an example, assume that the price of Brent crude oil for immediate delivery (the “spot” price), was $50 per barrel, and the value of a position in the near month futures contract was also $50. Over time, the price of the barrel of Brent crude oil will fluctuate based on a number of market factors, including demand for oil relative to its supply. The value of the near month contract will likewise fluctuate in reaction to a number of market factors. If investors seek to maintain their position in a near month contract and not take delivery of the oil, every month they must sell their current near month contract as it approaches expiration and invest in the next month contract.

If the futures market is in backwardation, e.g., when the expected price of Brent crude oil in the future would be less, the investor would be buying a next month contract for a lower price than the current near month contract. Using the $50 per barrel price above to represent the front month price, the price of the next month contract could be $49 per barrel, that is, 2% cheaper than the front month contract. Hypothetically, and assuming no other changes to either prevailing Brent crude oil prices or the price relationship between the spot price, the near month contract and the next month contract (and ignoring the impact of commission costs and the income earned on cash and/or cash equivalents), the value of the $49 next month contract would rise as it approaches expiration and becomes the new near month contract with a price of $50. In this example, the value of an investment in the second month contract would tend to rise faster than the spot price of Brent crude oil, or fall slower. As a result, it would be possible in this hypothetical example for the spot price of Brent crude oil to have risen 10% after some period of time, while the value of the investment in the second month futures contract would have risen 12%, assuming backwardation is large enough or enough time has elapsed. Similarly, the spot price of Brent crude oil could have fallen 10% while the value of an investment in the futures contract could have fallen only 8%. Over time, if backwardation remained constant, the difference would continue to increase.

If the futures market is in contango, the investor would be buying a next month contract for a higher price than the current near month contract. Using again the $50 per barrel price above to represent the front month price, the price of the next month contract could be $51 per barrel, that is, 2% more expensive than the front month contract. Hypothetically, and assuming no other changes to either prevailing Brent crude oil prices or the price relationship between the spot price, the near month contract and the next month contract (and ignoring the impact of commission costs and the income earned on cash and/or cash equivalents), the value of the next month contract would fall as it approaches expiration and becomes the new near month contract with a price of $50. In this example, it would mean that the value of an investment in the second month would tend to rise slower than the spot price of Brent crude oil, or fall faster. As a result, it would be possible in this hypothetical example for the spot price of Brent crude oil to have risen 10% after some period of time, while the value of the investment in the second month futures contract will have risen only 8%, assuming contango is large enough or enough time has elapsed. Similarly, the spot price of Brent crude oil could have fallen 10% while the value of an investment in the second month futures contract could have fallen 12%. Over time, if contango remained constant, the difference would continue to increase.

46

The chart below compares the price of the near month contract to the average price of the near 12-month contracts over the last 10 years (2002-2011). When the price of the near month contract is higher than the average price of the near 12 month contracts, the market would be described as being in backwardation. When the price of the near month contract is lower than the average price of the near 12 month contracts, the market would be described as being in contango. Although the prices of the near month contract and the average price of the near 12 month contracts do tend to move up or down together, it can be seen that at times the near month prices are clearly higher than the average price of the near 12 month contracts (backwardation), and other times they are below the average price of the near 12 month contracts (contango).

An alternative way to view the same data is to subtract from the dollar price of the near month contract the average dollar price of the near 12-months contracts for Brent crude oil. If the resulting number is a positive number, then the near month price is higher than the average price of the near 12-months contracts and the market could be described as being in backwardation. If the resulting number is a negative number, then the near month price is lower than the average price of the near 12-months contracts and the market could be described as being in contango. The chart below shows the results from subtracting the average dollar price of the near 12-month contracts from the near month price for the 10 year period between 2002 and 2012.

Historically, the crude oil futures markets have experienced periods of contango and backwardation, with backwardation being in place more often than contango. During 2006 and the first half of 2007, these markets experienced contango. However, starting early in the third quarter of 2007, the crude oil futures market moved into backwardation. The crude oil markets remained in backwardation until late in the second quarter of 2008 when they moved into contango. The crude oil markets remained in contango until late in the third quarter of 2008, when the markets moved into backwardation. Early in the fourth quarter of 2008, the crude oil market moved back into contango and remained in contango for the balance of 2008. Throughout 2009, the crude oil market remained in contango. During parts of January and February 2009, the level of contango was unusually steep. Crude oil inventories, which reached historic levels in January and February 2009 and which appeared to be the primary cause of the steep level of contango, began to drop in March 2009 and continued to drop for the balance of 2009 and the beginning of 2010. The crude oil futures market remained in contango through 2010 and 2011. The Brent crude oil futures market experiences the same effects of contango and backwardation as the United States crude oil futures market, but the Brent crude oil futures market has not historically experienced the same level of steepness in contango and backwardation as the United States crude oil futures market. As of December 31, 2012, U.S. crude oil markets remained mildly in contango while the market for Brent crude oil was mildly in backwardation.

Periods of contango or backwardation do not materially impact USBO’s investment objective of having the percentage changes in its per unit NAV track the daily percentage changes in the price of the Benchmark Futures Contract since the impact of backwardation and contango tend to equally impact the daily percentage changes in price of both USBO’s units and the Benchmark Futures Contract. It is impossible to predict with any degree of certainty whether backwardation or contango will occur in the future. It is likely that both conditions will occur during different periods.

Brent Crude Oil Market. During the year ended December 31, 2012, Brent crude oil prices were impacted by several factors. On the consumption side, demand increased inside and outside the United States as global economic growth, including emerging economies such as China and India, showed signs of slowing economic growth. Europe in particular showed signs of weakness as the ongoing financial and banking crisis raised concerns during the year ended December 31, 2012. On the supply side, efforts to reduce production by OPEC to more closely match global consumption were partially successful. In the summer of 2011, production had been disrupted by political unrest in the Middle East, particularly Libya, which reduced global supply by approximately 1.8 million barrels per day. A partial resolution of the Libyan situation has reduced concerns regarding the global supply of Brent crude oil. However, continuing concerns about the political standoff with Iran have left the market subject to bouts of heightened volatility as OPEC’s ability to replace Iranian oil currently subject to embargo is not unlimited. Brent crude oil prices finished 2012 approximately 3.47% higher than at the beginning of the year, as the global economy continues to adjust to periods of slow recovery and economic growth. the General Partner believes that should the global economic situation cease to improve, or decline, there is a meaningful possibility that crude oil prices could further retreat from their current levels, while any military actions involving Iran would likely have the opposite effect.

Brent Crude Oil Price Movements in Comparison to Other Energy Commodities and Investment Categories. the General Partner believes that investors frequently measure the degree to which prices or total returns of one investment or asset class move up or down in value in concert with another investment or asset class. Statistically, such a measure is usually done by measuring the correlation of the price movements of the two different investments or asset classes over some period of time. The correlation is scaled between 1 and -1, where 1 indicates that the two investment options move up or down in price or value together, known as “positive correlation,” and -1 indicates that they move in completely opposite directions, known as “negative correlation.” A correlation of 0 would mean that the movements of the two are neither positively nor negatively correlated, known as “non-correlation.” That is, the investment options sometimes move up and down together and other times move in opposite directions.

For the ten year time period between 2003 and 2012, the table below compares the monthly movements of Brent crude oil prices versus the monthly movements of the prices of several other energy commodities, such as natural gas, diesel-heating oil, and unleaded gasoline, as well as several major non-commodity investment asset classes, such as large cap U.S. equities, U.S. government bonds and global equities. It can be seen that over this particular time period, the movement of Brent crude oil on a monthly basis was not strongly correlated, positively or negatively, with the movements of large cap U.S. equities or U.S. government bonds. However, movements in Brent crude oil had a strong positive correlation to movements in unleaded gasoline and U.S. West Texas Intermediate (WTI) crude oil. Brent crude oil was also positively, yet mildly correlated with global equities and diesel-heating oil.

The table below covers a more recent, but much shorter, range of dates than the above table.  Over the one-year period ended December 31, 2012, Brent crude oil had a positive correlation with West Texas Intermediate Crude Oil and unleaded gasoline.  The correlation between Brent crude oil and both large cap U.S. equities and global equities, which had been essentially non-correlated over the ten-year period ended December 31, 2012, displayed results that indicated that they had a strong positive correlation over this shorter time period. Finally, the results showed that Brent crude oil, Heating Oil and U.S. government bonds, which had essentially been non-correlated for the ten-year period ended December 31, 2012, were negatively correlated over this more recent time period.

PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

Investors are cautioned that the historical price relationships between Brent crude oil and various other energy commodities, as well as other investment asset classes, as measured by correlation may not be reliable predictors of future price movements and correlation results. The results pictured above would have been different if a different range of dates had been selected. the General Partner believes that Brent crude oil has historically not demonstrated a strong correlation with equities or bonds over long periods of time.  However, the General Partner also believes that in the future it is possible that Brent crude oil could have long term correlation results that indicate prices of Brent crude oil more closely track the movements of equities or bonds.  In addition, the General Partner believes that, when measured over time periods shorter than ten years, there will always be some periods where the correlation of Brent crude oil to equities and bonds will be either more strongly positively correlated or more strongly negatively correlated than the long term historical results suggest.

The correlations between Brent crude oil, WTI Crude Oil, diesel-heating oil and gasoline are relevant because the General Partner endeavors to invest USBO’s assets in Futures Contracts and Other Crude Oil-Related Investments so that daily changes in percentage terms in USBO’s per unit NAV correlate as closely as possible with daily changes in percentage terms in the price of the Benchmark Futures Contract.  If certain other fuel-based commodity futures contracts do not closely correlate with the Futures Contract, then their use could lead to greater tracking error.  As noted above, the General Partner also believes that the changes in percentage terms in the price of the Benchmark Futures Contract will closely correlate with changes in percentage terms in the spot price of Brent crude oil.

What Is USBO’s Investment Strategy?

In managing USBO’s assets the General Partner does not use a technical trading system that issues buy and sell orders. The General Partner instead employs a quantitative methodology whereby each time a Creation Basket is sold, the General Partner purchases Crude Oil Interests, such as the Benchmark Futures Contract, that have an aggregate market value that approximates the amount of Treasuries and/or cash received upon the issuance of the Creation Basket.

As an example, assume that a Creation Basket is sold by USBO, and that USBO’s closing NAV per unit is $50. In that case, USBO would receive $2,500,000 in proceeds from the sale of the Creation Basket ($50.00 NAV per unit multiplied by 50,000 units, and excluding the Creation Basket fee). If one were to assume further that the General Partner wants to invest the entire proceeds from the Creation Basket in the Benchmark Futures Contract and that the market value of the Benchmark Futures Contract is $105,000, USBO would be unable to buy the exact number of Benchmark Futures Contracts with an aggregate market value equal to $2,500,000. Instead, USBO would be able to purchase 23 Benchmark Futures Contracts with an aggregate market value of $2,415,000. Assuming a margin requirement equal to 10% of the value of the Benchmark Futures Contract, USBO would be required to deposit $241,500 in Treasuries and cash and/or cash equivalents with the futures commission merchant through which the Benchmark Futures Contracts were purchased. The remainder of the proceeds from the sale of the Creation Basket, $2,258,500, would remain invested in cash, cash equivalents and Treasuries as determined by the General Partner from time to time based on factors such as potential calls for margin or anticipated redemptions.

50

The specific Futures Contracts purchased depend on various factors, including a judgment by the General Partner as to the appropriate diversification of USBO’s investments in Futures Contracts with respect to the month of expiration, and the prevailing price volatility of particular contracts. While the General Partner has made significant investments in ICE Futures Exchange Futures Contracts, for various reasons, including the ability to enter into the precise amount of exposure to the crude oil market, position limits or other regulatory requirements limiting USBO’s holdings, and market conditions, it may invest in Futures Contracts traded on other exchanges or in Other Crude Oil-Related Investments. To the extent that USBO invests in Other Crude-Oil Related Investments, it would prioritize investments in contracts and instruments that are economically equivalent to the Benchmark Futures Contract, including cleared swaps that satisfy such criteria, and then, to a lesser extent, it would invest in other types of cleared swaps and other contracts, instruments and swaps, including swaps in the over-the-counter market. If USBO is required by law or regulation, or by one of its regulators, including a Futures Exchange, to reduce its position in the Benchmark Futures Contracts to the applicable position limit or to a specified accountability level or if market conditions dictate it would be more appropriate to invest in Other Crude Oil-Related Investments, a substantial portion of USBO’s assets could be invested in accordance with such priority in Other Crude Oil-Related Investments that are intended to replicate the return on the Benchmark Futures Contract. As USBO’s assets reach higher levels, it is more likely to exceed position limits, accountability levels or other regulatory limits and, as a result, it is more likely that it will invest in accordance with such priority in Other Crude Oil-Related Investments at such higher levels. In addition, market conditions that the General Partner currently anticipates could cause USBO to invest in Other Crude Oil-Related Investments include those allowing USBO to obtain greater liquidity or to execute transactions with more favorable pricing. But see “What are the Risk Factors Involved with an Investment in USBO? — Risks Associated With Investing Directly or Indirectly in Crude Oil — Regulation of the commodity interests and energy markets is extensive and constantly changing; future regulatory developments are impossible to predict but may significantly and adversely affect USBO” for a discussion of the potential impact of the Dodd-Frank Act on USBO’s ability to invest in OTC transactions and cleared swaps.

The General Partner may not be able to fully invest USBO’s assets in Benchmark Futures Contracts having an aggregate notional amount exactly equal to USBO’s NAV. For example, as standardized contracts, the Benchmark Futures Contracts are for a specified amount of a particular commodity, and USBO’s NAV and the proceeds from the sale of a Creation Basket are unlikely to be an exact multiple of the amounts of those contracts. As a result, in such circumstances, USBO may be better able to achieve the exact amount of exposure to changes in price of the Benchmark Futures Contracts through the use of Other Crude Oil-Related Investments, such as over-the-counter contracts that have better correlation with changes in price of the Benchmark Futures Contract.

USBO anticipates that to the extent it invests in Futures Contracts other than crude oil contracts (such as futures contracts natural gas, gasoline, heating oil and other petroleum-based fuels) and Other Crude Oil-Related Investments, it will enter into various non-exchange-traded derivative contracts to hedge the short-term price movements of such Futures Contracts and Other Crude Oil-Related Investments against the current Benchmark Futures Contract.

The General Partner does not anticipate letting USBO’s Futures Contracts expire and taking delivery of the underlying commodity. Instead, the General Partner closes existing positions, e.g., when it changes the Benchmark Futures Contract or it otherwise determines it would be appropriate to do so and reinvests the proceeds in new Futures Contracts or Other Crude Oil-Related Investments. Positions may also be closed out to meet orders for Redemption Baskets and in such case proceeds for such baskets will not be reinvested.

By remaining invested as fully as possible in Futures Contracts or Other Crude Oil-Related Investments, the General Partner believes that the changes in percentage terms in USBO’s NAV will continue to closely track the changes in percentage terms in the prices of the Benchmark Futures Contract. The General Partner believes that certain arbitrage opportunities result in the price of the units traded on the NYSE Arca closely tracking the NAV of USBO. Additionally, crude oil futures contracts traded on the ICE Futures have closely tracked the spot price of Brent crude oil. Based on these expected interrelationships, the General Partner believes that the daily changes in the price of USBO’s units traded on the NYSE Arca have closely tracked and will continue to closely track the daily changes in the spot price of Brent crude oil.

What are Futures Contracts?

Futures Contracts are agreements between two parties. One party agrees to buy a commodity such as Brent crude oil from the other party at a later date at a price and quantity agreed-upon when the contract is made. Futures Contracts are traded on futures exchanges, including the ICE Futures. For example, the Benchmark Futures Contract is traded on the ICE Futures in units of 1,000 barrels. The Brent crude Futures Contracts traded on the ICE Futures are priced by an electronic, screen-based system that determines the price by matching electronically offers to purchase and sell. Additional risks of investing in Futures Contracts are discussed below. Additional risks of investing in Futures Contracts are included in “What are the Risk Factors Involved with an Investment in USBO?”

51

Impact of Accountability Levels, Position Limits and Price Fluctuation Limits. Futures contracts include typical and significant characteristics. Most significantly, the CFTC and U.S. designated contract markets such as the NYMEX have established accountability levels and position limits on the maximum net long or net short futures contracts in commodity interests that any person or group of persons under common trading control (other than as a hedge, which an investment by USBO is not) may hold, own or control. The net position is the difference between an individual or firm’s open long contracts and open short contracts in any one commodity. In addition, most U.S. based futures exchanges, such as the NYMEX, limit the daily price fluctuation for futures contracts. Currently, the ICE Futures imposes position and accountability limits that are similar to those imposed by U.S. based futures exchanges and also limits the maximum daily price fluctuation, while some other non-U.S. futures exchanges have not adopted such limits.

The accountability levels for the Benchmark Futures Contract and other Futures Contracts traded on U.S.-based futures exchanges, such as the NYMEX, are not a fixed ceiling, but rather a threshold above which the NYMEX may exercise greater scrutiny and control over an investor’s positions. The current accountability level for net long or short positions at any one time in the NYMEX Contract for light, sweet crude oil Futures Contracts is 20,000 net future contracts. In addition, the ICE Futures maintains the same accountability levels, position limits and monitoring authority for its light, sweet crude oil contracts as the NYMEX. If USBO and the Related Public Funds exceed this accountability level for investments in the futures contract for light, sweet crude oil, the NYMEX and ICE Futures will monitor such exposure and may ask for further information on their activities, including the total size of all positions, investment and trading strategy, and the extent of liquidity resources of USBO and the Related Public Funds. If deemed necessary by the NYMEX and/or ICE Futures, USBO could be ordered to reduce its aggregate position back to the accountability level. In contrast, the position limits for the ICE Futures maintain that when 100 lots or more are traded, the activity must be reported to the exchange on a daily basis. ICE Futures also maintains that an Expiration Limit of 6,000 lots, long or short, will apply for the five business days up to and including the expiration date. There are no specific position accountability levels or limits, nor are there are any maximum daily price fluctuation limits for the ICE Brent Crude Oil (physically settled) futures contract. USBO did not exceed accountability levels of the NYMEX or ICE Futures during the year ended December 31, 2012. As of December 31, 2012, USBO held 406 Futures Contracts for Brent crude oil traded on the ICE Futures.

Position limits differ from accountability levels in that they represent fixed limits on the maximum number of futures contracts that any person may hold and cannot allow such limits to be exceeded without express CFTC authority to do so. In addition to accountability levels and position limits that may apply at any time, the ICE Futures Exchange and the NYMEX impose position limits on contracts held in the last few days of trading in the near month contract to expire. It is unlikely that USBO will run up against such position limits because USBO’s investment strategy is to close out its positions and “roll” from the near month contract to expire to the next month contract during a four-day period beginning two weeks from expiration of the contract. For the year ended December 31, 2012, USBO did not exceed any position limits imposed by NYMEX and ICE Futures.

 In late 2011, the CFTC adopted rules that impose new position limits on Referenced Contracts (as defined below) involving 28 energy, metals and agricultural commodities (the “Position Limit Rules”). The Position Limit Rules were scheduled to become effective on October 12, 2012. However, on September 28, 2012, the United States District Court for the District of Columbia vacated these regulations on the basis of ambiguities in the provisions of the CEA (as modified by the Dodd-Frank Act) upon which the regulations were based. In its September 28, 2012 decision, the court remanded the Position Limit Rules to the CFTC with instructions to use its expertise and experience to resolve the ambiguities in the statute. On November 15, 2012, the CFTC indicated that it will move forward with an appeal of the District Court’s decision to vacate the Position Limit Rules. At this time, it is not possible to predict how the CFTC’s appeal could affect USBO, but it may be substantial and adverse. Furthermore, until such time as the appeal is resolved or, if applicable revisions to the Position Limit Rules are proposed and adopted, the regulatory architecture in effect prior to the enactment of the Position Limit Rules will govern transactions in commodities and related derivatives (collectively, “Referenced Contracts”). Under that system, the CFTC enforces federal limits on speculation in agricultural products (e.g., corn, wheat and soy), while futures exchanges enforce position limits and accountability levels for agricultural and certain energy products (e.g., oil and natural gas). As a result, USBO may be limited with respect to the size of its investments in any commodities subject to these limits. Finally, subject to certain narrow exceptions, the vacated Position Limit Rules would have required the aggregation, for purposes of the position limits, of all positions in the 28 Referenced Contracts held by a single entity and its affiliates, regardless of whether such position existed on U.S. futures exchanges, non-U.S. futures exchanges, in cleared swaps or in over-the-counter swaps. The CFTC is presently considering new aggregation rules, under a rulemaking proposal that is distinct from the Position Limit Rules. At this time, it is unclear how any modified aggregation rules may affect USBO, but it may be substantial and adverse. By way of example, the aggregation rules in combination with any potential revised Position Limit Rules may negatively impact the ability of USBO to meet its investment objectives through limits that may inhibit the General Partner’s ability to sell additional Creation Baskets of USBO.

If another halt were triggered, the market would continue to be expanded by $3.00 per mmBtu in either direction after each successive five-minute trading halt. There will be no maximum price fluctuation limits during any one trading session.

Price Volatility. The price volatility of Futures Contracts generally has been historically greater than that for traditional securities such as stocks and bonds. Price volatility often is greater day-to-day as opposed to intra-day. Futures Contracts tend to be more volatile than stocks and bonds because price movements for crude oil are more currently and directly influenced by economic factors for which current data is available and are traded by crude oil futures traders throughout the day. Because USBO invests a significant portion of its assets in Futures Contracts, the assets of USBO, and therefore the prices of USBO units, may be subject to greater volatility than traditional securities.

Marking-to-Market Futures Positions. Futures Contracts are marked to market at the end of each trading day and the margin required with respect to such contracts is adjusted accordingly. This process of marking-to-market is designed to prevent losses from accumulating in any futures account. Therefore, if USBO’s futures positions have declined in value, USBO may be required to post “variation margin” to cover this decline. Alternatively, if USBO futures positions have increased in value, this increase will be credited to USBO’s account.

USBO anticipates that to the extent it invests in Futures Contracts other than Brent crude oil contracts (such as futures contracts for WTI light, sweet crude oil) and Other Crude Oil-Related Investments, it will enter into various non-exchange-traded derivative contracts to hedge the short-term price movements of such Futures Contracts and Other Crude Oil-Related Investments against the current Benchmark Futures Contract.

What is the Crude Oil Market and the Petroleum-Based Fuel Market?

Brent Crude Oil. Crude oil is the world’s most actively traded commodity. The futures contracts for Brent crude oil that are traded on the ICE Futures Exchange are the world’s second most liquid forum for crude oil trading, as well as the world’s second largest volume futures contract trading on a physical commodity. Due to the liquidity and price transparency of light, sweet crude oil futures contracts, they are used as a principal international pricing benchmark. The futures contracts for Brent crude oil trade on the ICE Futures Exchange in units of 1,000 U.S. barrels and, if not closed out before maturity, will result in delivery of oil to Sullom Voe, an oil terminal located in the Shetland Island near Scotland, which is also accessible to the international spot markets by tanker.

The price of crude oil is established by the supply and demand conditions in the global market overall, and more particularly, in the main refining centers of Singapore, Northwest Europe, and the U.S. Gulf Coast. Demand for petroleum products by consumers, as well as agricultural, manufacturing and transportation industries, determines demand for crude oil by refiners. Since the precursors of product demand are linked to economic activity, crude oil demand will tend to reflect economic conditions. However, other factors such as weather also influence product and crude oil demand. The price of Brent crude oil has historically been volatile.

Heating Oil. Heating oil, also known as No. 2 fuel oil, accounts for approximately 25% of the yield of a barrel of crude oil, the second largest “cut” from oil after gasoline. The heating oil futures contract listed and traded on the NYMEX, trades in units of 42,000 gallons (1,000 barrels) and is based on delivery in the New York harbor, the principal cash market-trading center. The price of heating oil has historically been volatile.

54

Gasoline. Gasoline is the largest single volume refined product sold in the U.S. and accounts for almost half of national oil consumption. The gasoline futures contract listed and traded on the NYMEX, trades in units of 42,000 gallons (1,000 barrels) and is based on delivery at petroleum products terminals in the New York harbor, the major East Coast trading center for imports and domestic shipments from refineries in the New York harbor area or from the Gulf Coast refining centers. The price of gasoline has historically been volatile.

Natural Gas. Natural gas accounts for almost a quarter of U.S. energy consumption. The natural gas futures contract listed and traded on the NYMEX trades in units of 10,000 mmBtu and is based on delivery at the Henry Hub in Louisiana, the nexus of 16 intra- and interstate natural gas pipeline systems that draw supplies from the region’s prolific gas deposits. The pipelines serve markets throughout the U.S. East Coast, the Gulf Coast, the Midwest, and up to the Canadian border. The price of natural gas has historically been volatile.

As noted, the General Partner also believes that the changes in the price of the Benchmark Futures Contract will closely correlate with changes in the spot price of Brent crude oil. Assuming that the units’ value tracks the Benchmark Futures Contract as intended, the stated objective of USBO for the units’ NAV to reflect the performance of the spot price of Brent crude oil would be met if the trend reflected over the past ten years were to continue. However, there is no guarantee that such trend will continue.

USBO may invest in certain other fuel-based commodity futures contracts. The chart below illustrates the historical correlation between the Benchmark Futures Contract and certain other fuel-based commodity futures contracts in which USBO may invest over the last ten years. These correlations are relevant because the General Partner endeavors to invest USBO’s assets in Futures Contracts and Other Crude Oil-Related Investments so that daily changes in USBO’s NAV correlate as closely as possible with daily changes in the price of the Benchmark Futures Contract. If USBO invests in other fuel-based commodity futures contracts and such contracts do not closely correlate with the Futures Contracts then their use could lead to greater tracking error.

The degree of correlation varies both among the different commodities and also over time. As such, the use of any energy related commodity to hedge a different energy commodity can only produce, at best, an imperfect hedge.

Why Does USBO Purchase and Sell Futures Contracts?

USBO’s investment objective is for the daily changes in percentage terms of its units’ NAV to reflect the daily changes in percentage terms of the Benchmark Futures Contract, less USBO’s expenses. USBO invests primarily in Futures Contracts. USBO seeks to have its aggregate NAV approximate at all times the aggregate market value of the Futures Contracts and Other Crude Oil-Related Investments it holds.

In connection with investing in Futures Contracts and Other Crude Oil-Related Investments, USBO holds Treasuries, cash and/or cash equivalents that serve as segregated assets supporting USBO’s positions in Futures Contracts and Other Crude Oil-Related Investments. For example, the purchase of a Futures Contract with a stated value of $10 million would not require USBO to pay $10 million upon entering into the contract; rather, only a margin deposit, generally of 5% to 30% of the stated value of the Futures Contract, would be required. To secure its Futures Contract obligations, USBO would deposit the required margin with the futures commission merchant and would separately hold, through its Custodian, Treasuries, cash and/or cash equivalents in an amount equal to the balance of the current market value of the contract, which at the contract’s inception would be $10 million minus the amount of the margin deposit, or $9 million (assuming a 10% margin).

As a result of the foregoing, typically 5% to 30% of USBO’s assets are held as margin in segregated accounts with a futures commission merchant. In addition to the Treasuries or cash it posts with the futures commission merchant for the Futures Contracts it owns, USBO holds, through the Custodian, Treasuries, cash and/or cash equivalents that can be posted as margin or as collateral to support its over-the-counter contracts. USBO earns income from the Treasuries and/or cash equivalents that it purchases, and on the cash it holds through the Custodian. USBO anticipates that the earned income will increase the NAV and limited partners’ capital contribution accounts. USBO reinvests the earned income, holds it in cash, or uses it to pay its expenses. If USBO reinvests the earned income, it makes investments that are consistent with its investment objective.

What is the Flow of Units?

What are the Trading Policies of USBO?

Liquidity

USBO invests only in Futures Contracts and Other Crude Oil-Related Investments that, in the opinion of the General Partner, are traded in sufficient volume to permit the ready taking and liquidation of positions in these financial interests.

Spot Commodities

While certain of the Futures Contracts traded on the ICE Futures can be physically settled, USBO does not intend to take or make physical delivery. USBO may from time to time trade in Other Crude Oil-Related Investments, including contracts based on the spot price of Brent crude oil.

Leverage

The General Partner endeavors to have the value of USBO’s Treasuries, cash and/or cash equivalents, whether held by USBO or posted as margin or collateral, at all times approximate the aggregate market value of its obligations under USBO’s Futures Contracts and Other Crude Oil-Related Investments. Commodity pools’ trading positions in futures contracts or other related investments are typically required to be secured by the deposit of margin funds that represent only a small percentage of a futures contract’s (or other commodity interest’s) entire market value. While the General Partner does not intend to leverage USBO’s assets, it is not prohibited from doing so under the LP Agreement.

Borrowings

Borrowings are not used by USBO unless USBO is required to borrow money in the event of physical delivery, if USBO trades in cash commodities, or for short-term needs created by unexpected redemptions.

56

Over-the-Counter Derivatives (Including Spreads and Straddles)

In addition to Futures Contracts, there are also a number of listed options on the Futures Contracts on the principal futures exchanges. These contracts offer investors and hedgers another set of financial vehicles to use in managing exposure to the Brent crude oil market. Consequently, USBO may purchase options on Brent crude oil Futures Contracts on these exchanges in pursuing its investment objective.

In addition to the Futures Contracts and options on the Futures Contracts, there also exists an active non-exchange-traded market in derivatives tied to crude oil. These derivatives transactions (also known as over-the-counter contracts) are usually entered into between two parties in private contracts. Unlike most of the exchange-traded Futures Contracts or exchange-traded options on the Futures Contracts, each party to such contract bears the credit risk of the other party, i.e., the risk that the other party may not be able to perform its obligations under its contract.

To reduce the credit risk that arises in connection with such contracts, USBO will generally enter into an agreement with each counterparty based on the Master Agreement published by the International Swaps and Derivatives Association, Inc. (“ISDA”) that provides for the netting of its overall exposure to its counterparty.

The General Partner assesses or reviews, as appropriate, the creditworthiness of each potential or existing counterparty to an over-the-counter contract pursuant to guidelines approved by the General Partner’s Board.

USBO may employ spreads or straddles in its trading to mitigate the differences in its investment portfolio and its goal of tracking the price of the Benchmark Futures Contract. USBO would use a spread when it chooses to take simultaneous long and short positions in futures written on the same underlying asset, but with different delivery months.

USBO has not employed any hedging methods since all of its investments have been made over an exchange. Therefore, USBO has not been exposed to counterparty risk.

Pyramiding

USBO has not and will not employ the technique, commonly known as pyramiding, in which the speculator uses unrealized profits on existing positions as variation margin for the purchase or sale of additional positions in the same or another commodity interest.

UBS is and has been a defendant in numerous legal proceedings, including actions brought by regulatory organizations and government agencies, relating to its securities and commodities business that allege various violations of federal and state securities laws. UBS AG, the ultimate parent company to UBS Securities, files annual reports and quarterly reports to the SEC in which it discloses material information about matters involving but not limited to, UBS Securities, including information about any material litigation or regulatory investigations (https://www.ubs.com/global/en/about_ubs/investor_relations/quarterly_reporting/2011.html). Actions with respect to UBS Securities’ FCM business are publicly available on the website of the National Futures Association (http://www.nfa.futures.org/).

On June 27, 2007, the Securities Division of the Secretary of the Commonwealth of Massachusetts (“Massachusetts Securities Division”) filed an administrative complaint (the “Complaint”) and notice of adjudicatory proceeding against UBS Securities, captioned In The Matter of UBS Securities, LLC, Docket No. E-2007-0049, which alleged that UBS Securities violated the Massachusetts Uniform Securities Act (the “Act”) and related regulations by providing the advisers for certain hedge funds with gifts and gratuities in the form of below market office rents, personal loans with below market interest rates, event tickets, and other perks, in order to induce those hedge fund advisers to increase or retain their level of prime brokerage fees paid to UBS Securities. On November 22, 2010, UBS Securities entered into a Consent Order and Settlement with the Massachusetts Securities Division, pursuant to which UBS Securities agreed to implementing a disclosure policy and retaining an independent consultant to monitor the policy. UBS Securities also paid a $100,000 fine.

In the summer of 2008, the Massachusetts Securities Division, Texas State Securities Board, and the New York Attorney General (“NYAG”) all brought actions against UBS and UBS Financial Services, Inc. (“UBS Financial”), alleging violations of various state law anti-fraud provisions in connection with the marketing and sale of auction rate securities.

On August 8, 2008, UBS Securities and UBS Financial Services reached agreements with the SEC, the NYAG, the Massachusetts Securities Division and other state regulatory agencies represented by the North American Securities Administrators Association (“NASAA”) to restore liquidity to all remaining client’s holdings of auction rate securities by June 30, 2012. On October 2, 2008, UBS Securities and UBS Financial entered into a final consent agreement with the Massachusetts Securities Division settling all allegations in the Massachusetts Securities Division’s administrative proceeding against UBS Securities and UBS Financial with regards to the auction rate securities matter. On December 11, 2008, UBS Securities and UBS Financial executed an Assurance of Discontinuance in the auction rate securities settlement with the NYAG. On the same day, UBS Securities and UBS Financial finalized settlements with the SEC. UBS Securities and UBS Financial paid penalties of $75 million to NYAG and an additional $75 million to be apportioned among the participating NASAA states. In March 2010, UBS Securities and UBS Financial and NASAA agreed on final settlement terms, pursuant to which, UBS Securities and UBS Financial agreed to provide client liquidity up to an additional $200 million.

On August 14, 2008 the New Hampshire Bureau of Securities Regulation (the “Bureau”) filed an administrative action against UBS Securities relating to a student loan issuer, the New Hampshire Higher Education Loan Corp. (“NHHELCO”). The complaint alleged fraudulent and unethical conduct in violation of New Hampshire state statutes. On April 14, 2010, UBS entered into a Consent Order resolving all of the Bureau’s claims. UBS Securities paid $750,000 to the Bureau for all costs associated with the Bureau’s investigation. UBS Securities entered a separate civil settlement with NHHELCO and provided a total financial benefit of $20 million to NHHELCO.

On April 29, 2010, the CFTC issued an order with respect to UBS Securities and levied a fine of $200,000. The Order stated that on February 6, 2009, UBS Securities’ employee broker aided and abetted UBS Securities’ customer’s concealment of material facts from the NYMEX in violation of Section 9(a)(4) of the CEA, 7 U.S.C. § 13(a)(4) (2006). Pursuant to NYMEX Rules, a block trade must be reported to NYMEX “within five minutes of the time of execution” consistent with the requirements of NYMEX Rule 6.21C(A)(6). Although the block trade in question was executed earlier in the day, UBS Securities’ employee broker aided and abetted its customer’s concealment of facts when, in response to the customer’s request to delay reporting the trade until after the close of trading, UBS Securities’ employee did not report the trade until after the close. Because the employee broker undertook his actions within the scope of his employment, pursuant to Section 2(a)(1)(B) of the CEA, 7 U.S.C. § 2(a)(1)(B) (2006), and Commission Regulation 1.2, 17 C.F.R. § 1.2 (2009), UBS Securities is liable for the employee broker’s aiding and abetting of its customer’s violation of Section 9(a)(4) of the CEA. The fine has been paid and the matter is now closed.

UBS Securities will act only as clearing broker for USBO and as such will be paid commissions for executing and clearing trades on behalf of USBO. UBS Securities has not passed upon the adequacy or accuracy of this annual report on Form 10-K. UBS Securities neither will act in any supervisory capacity with respect to the General Partner nor participate in the management of the General Partner or USBO.

UBS Securities is not affiliated with USBO or the General Partner. Therefore, USBO does not believe that USBO has any conflicts of interest with UBS Securities or their trading principals arising from their acting as USBO’s FCM.

58

Currently, the General Partner does not employ commodity trading advisors for trading of USBO contracts. The General Partner currently does, however, employ a trading advisor for USCI, CPER, USAG and USMI, SummerHaven Investment Management, LLC (“SummerHaven”). If, in the future, the General Partner does employ commodity trading advisors for USBO, it will choose each advisor based on arm’s-length negotiations and will consider the advisor’s experience, fees and reputation.

Form of Units

Registered Form. Units are issued in registered form in accordance with the LP Agreement. The Administrator has been appointed registrar and transfer agent for the purpose of transferring units in certificated form. The Administrator keeps a record of all limited partners and holders of the units in certificated form in the registry (the “Register”). The General Partner recognizes transfers of units in certificated form only if done in accordance with the LP Agreement. The beneficial interests in such units are held in book-entry form through participants and/or accountholders in DTC.

Book Entry. Individual certificates are not issued for the units. Instead, units are represented by one or more global certificates, which are deposited by the Administrator with DTC and registered in the name of Cede & Co., as nominee for DTC. The global certificates evidence all of the units outstanding at any time. Unitholders are limited to (1) participants in DTC such as banks, brokers, dealers and trust companies (“DTC Participants”), (2) those who maintain, either directly or indirectly, a custodial relationship with a DTC Participant (“Indirect Participants”), and (3) those who hold interests in the units through DTC Participants or Indirect Participants, in each case who satisfy the requirements for transfers of units. DTC Participants acting on behalf of investors holding units through such participants’ accounts in DTC will follow the delivery practice applicable to securities eligible for DTC’s Same-Day Funds Settlement System. Units are credited to DTC Participants’ securities accounts following confirmation of receipt of payment.

60

DTC. DTC has advised us as follows. It is a limited purpose trust company organized under the laws of the State of New York and is a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities for DTC Participants and facilitates the clearance and settlement of transactions between DTC Participants through electronic book-entry changes in accounts of DTC Participants.

Transfer of Units

Transfers of Units Only Through DTC. The units are only transferable through the book-entry system of DTC. Limited partners who are not DTC Participants may transfer their units through DTC by instructing the DTC Participant holding their units (or by instructing the Indirect Participant or other entity through which their units are held) to transfer the units. Transfers are made in accordance with standard securities industry practice.

Transfers of interests in units with DTC are made in accordance with the usual rules and operating procedures of DTC and the nature of the transfer. DTC has established procedures to facilitate transfers among the participants and/or accountholders of DTC. Because DTC can only act on behalf of DTC Participants, who in turn act on behalf of Indirect Participants, the ability of a person or entity having an interest in a global certificate to pledge such interest to persons or entities that do not participate in DTC, or otherwise take actions in respect of such interest, may be affected by the lack of a certificate or other definitive document representing such interest.

DTC has advised USBO that it will take any action permitted to be taken by a unitholder (including, without limitation, the presentation of a global certificate for exchange) only at the direction of one or more DTC Participants in whose account with DTC interests in global certificates are credited and only in respect of such portion of the aggregate principal amount of the global certificate as to which such DTC Participant or Participants has or have given such direction.

Transfer/Application Requirements. All purchasers of USBO’s units, and potentially any purchasers of units in the future, who wish to become limited partners or other record holders and receive cash distributions, if any, or have certain other rights, must deliver an executed transfer application in which the purchaser or transferee must certify that, among other things, he, she or it agrees to be bound by USBO’s LP Agreement and is eligible to purchase USBO’s securities. Each purchaser of units must execute a transfer application and certification. The obligation to provide the form of transfer application is imposed on the seller of units or, if a purchase of units is made through an exchange, the form may be obtained directly through USBO. Further, the General Partner may request each record holder to furnish certain information, including that record holder’s nationality, citizenship or other related status. A record holder is a unitholder that is, or has applied to be, a limited partner. An investor who is not a U.S. resident may not be eligible to become a record holder or one of USBO’s limited partners if that investor’s ownership would subject USBO to the risk of cancellation or forfeiture of any of USBO’s assets under any federal, state or local law or regulation. If the record holder fails to furnish the information or if the General Partner determines, on the basis of the information furnished by the holder in response to the request, that such holder is not qualified to become one of USBO’s limited partners, the General Partner may be substituted as a holder for the record holder, who will then be treated as a non-citizen assignee, and USBO will have the right to redeem those securities held by the record holder.

A transferee’s broker, agent or nominee may complete, execute and deliver a transfer application and certification. USBO may, at its discretion, treat the nominee holder of a unit as the absolute owner. In that case, the beneficial holder’s rights are limited solely to those that it has against the nominee holder as a result of any agreement between the beneficial owner and the nominee holder.

A person purchasing USBO’s existing units, who does not execute a transfer application and certify that the purchaser is eligible to purchase those securities acquires no rights in those securities other than the right to resell those securities. Whether or not a transfer application is received or the consent of the General Partner obtained, USBO’s units are securities and are transferable according to the laws governing transfers of securities.

Any transfer of units will not be recorded by the transfer agent or recognized by the General Partner unless a completed transfer application is delivered to the General Partner or the Administrator. When acquiring units, the transferee of such units that completes a transfer application will:

• be an assignee until admitted as a substituted limited partner upon the consent and sole discretion of the General Partner and the recording of the assignment on the books and records of the partnership;

• automatically request admission as a substituted limited partner;

• agree to be bound by the terms and conditions of, and execute, USBO’s LP Agreement;

• represent that such transferee has the capacity and authority to enter into USBO’s LP Agreement;

• grant powers of attorney to the General Partner as general partner of USBO and any liquidator of USBO; and

• make the consents and waivers contained in USBO’s LP Agreement.

61

An assignee will become a limited partner in respect of the transferred units upon the consent of the General Partner as general partner of USBO and the recordation of the name of the assignee on USBO’s books and records. Such consent may be withheld in the sole discretion of the General Partner.

If consent of the General Partner is withheld, such transferee shall be an assignee. An assignee shall have an interest in the partnership equivalent to that of a limited partner with respect to allocations and distributions, including, without limitation, liquidating distributions, of the partnership. With respect to voting rights attributable to units that are held by assignees, the General Partner shall be deemed to be the limited partner with respect thereto and shall, in exercising the voting rights in respect of such units on any matter, vote such units at the written direction of the assignee who is the record holder of such units. If no such written direction is received, such units will not be voted. An assignee shall have no other rights of a limited partner.

Until a unit has been transferred on USBO’s books, USBO and the transfer agent may treat the record holder of the unit as the absolute owner for all purposes, except as otherwise required by law or stock exchange regulations.

Withdrawal of Limited Partners

As discussed in the LP Agreement, if the General Partner gives at least fifteen (15) days’ written notice to a limited partner, then the General Partner may for any reason, in its sole discretion, require any such limited partner to withdraw entirely from the partnership or to withdraw a portion of its partner capital account. If the General Partner does not give at least fifteen (15) days’ written notice to a limited partner, then it may only require withdrawal of all or any portion of the capital account of any limited partner in the following circumstances: (i) the unitholder made a misrepresentation to the General Partner in connection with its purchase of units; or (ii) the limited partner’s ownership of units would result in the violation of any law or regulations applicable to the partnership or a partner. In these circumstances, the General Partner without notice may require the withdrawal at any time, or retroactively. The limited partner thus designated shall withdraw from the partnership or withdraw that portion of its partner capital account specified, as the case may be, as of the close of business on such date as determined by the General Partner. The limited partner thus designated shall be deemed to have withdrawn from the partnership or to have made a partial withdrawal from its partner capital account, as the case may be, without further action on the part of the limited partner and the provisions of the LP Agreement shall apply.

What is the Plan of Distribution?

Buying and Selling Units

Most investors buy and sell units of USBO in secondary market transactions through brokers. Units trade on the NYSE Arca under the ticker symbol “BNO”. Units are bought and sold throughout the trading day like other publicly traded securities. When buying or selling units through a broker, most investors incur customary brokerage commissions and charges. Investors are encouraged to review the terms of their brokerage account for details on applicable charges and, as discussed below under “U.S. Federal Income Tax Considerations,” any provisions authorizing the broker to borrow units held on your behalf.

Marketing Agent and Authorized Purchasers

The offering of USBO’s units is a best efforts offering. USBO continuously offers Creation Baskets consisting of 50,000 units through the Marketing Agent, to Authorized Purchasers. Merrill Lynch Professional Clearing Corp. was the initial Authorized Purchaser. Authorized Purchasers pay a $350 fee for each order to create one or more Creation Baskets through May 1, 2014; on and after May 2, 2014, the fee increases to $1,000. The Marketing Agent receives, for its services as marketing agent to USBO, a marketing fee of 0.06% on USBO’s assets up to the first $3 billion; and 0.04% on USBO’s assets in excess of $3 billion;, provided, however, that in no event may the aggregate compensation paid to the Marketing Agent and any affiliate of the General Partner for distribution- – related services in connection with this offering exceed ten percent (10%) of the gross proceeds of this offering.

The offering of baskets is being made in compliance with Conduct Rule 2310 of FINRA. Accordingly, Authorized Purchasers will not make any sales to any account over which they have discretionary authority without the prior written approval of a purchaser of units.

The per unit price of units offered in Creation Baskets on any subsequent day will be the total NAV of USBO calculated shortly after the close of the core trading session on the NYSE Arca on that day divided by the number of issued and outstanding units. An Authorized Purchaser is not required to sell any specific number or dollar amount of units.

By executing an Authorized Purchaser Agreement, an Authorized Purchaser becomes part of the group of parties eligible to purchase baskets from, and put baskets for redemption to, USBO. An Authorized Purchaser is under no obligation to create or redeem baskets, and an Authorized Purchaser is under no obligation to offer to the public units of any baskets it does create.

62

A list of Authorized Purchasers is available from the Marketing Agent. Because new units can be created and issued on an ongoing basis, at any point during the life of USBO, a “distribution”, as such term is used in the 1933 Act, will be occurring. Authorized Purchasers, other broker-dealers and other persons are cautioned that some of their activities may result in their being deemed participants in a distribution in a manner that would render them statutory underwriters and subject them to the prospectus-delivery and liability provisions of the 1933 Act. In addition, any purchaser who purchases units with a view towards distribution of such units may be deemed to be a statutory underwriter.

Authorized Purchasers will comply with the prospectus-delivery requirements in connection with the sale of units to customers. For example, an Authorized Purchaser, other broker-dealer firm or its client will be deemed a statutory underwriter if it purchases a basket from USBO, breaks the basket down into the constituent units and sells the units to its customers; or if it chooses to couple the creation of a supply of new units with an active selling effort involving solicitation of secondary market demand for the units. Authorized Purchasers may also engage in secondary market transactions in units that would not be deemed “underwriting”. For example, an Authorized Purchaser may act in the capacity of a broker or dealer with respect to units that were previously distributed by other Authorized Purchasers. A determination of whether a particular market participant is an underwriter must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that would lead to designation as an underwriter and subject them to the prospectus-delivery and liability provisions of the 1933 Act.

Dealers who are neither Authorized Purchasers nor “underwriters” but are nonetheless participating in a distribution (as contrasted to ordinary secondary trading transactions), and thus dealing with units that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus-delivery exemption provided by Section 4(3) of the 1933 Act.

The General Partner may qualify the units in states selected by the General Partner and intends that sales be made through broker-dealers who are members of FINRA. Investors intending to create or redeem baskets through Authorized Purchasers in transactions not involving a broker-dealer registered in such investor’s state of domicile or residence should consult their legal advisor regarding applicable broker-dealer or securities regulatory requirements under the state securities laws prior to such creation or redemption.

While the Authorized Purchasers may be indemnified by the General Partner, they will not be entitled to receive a discount or commission from USBO for their purchases of Creation Baskets. The difference between the price paid by Authorized Purchasers as underwriters and the price paid to such Authorized Purchasers by investors will be deemed underwriting compensation.

Calculating NAV

USBO’s NAV is calculated by:

• Taking the current market value of its total assets; and

• Subtracting any liabilities; and

• Dividing that total by the total number of outstanding units.

The Administrator calculates the NAV of USBO once each NYSE Arca trading day. The per unit NAV for a particular trading day is released after 4:00 p.m. New York time. Trading during the core trading session on the NYSE Arca typically closes at 4:00 p.m. New York time. The Administrator uses the ICE Futures Exchange settlement price (a weighted average price of trades during a three minute settlement period from 2:27 p.m. to 2:30 p.m. New York time) for the contracts traded on the ICE Futures Exchange, but calculates or determines the value of all other USBO investments (including Futures Contracts not traded on NYMEX, Other Crude Oil-Related Investments and Treasuries) using market quotations, if available, or other information customarily used to determine the fair value of such as of the earlier of the close of the NYSE Arca or 4:00 p.m. New York time, in accordance with the current Administrative Agency Agreement among BBH&Co., USBO and the General Partner. “Other information” customarily used in determining fair value includes information consisting of market data in the relevant market supplied by one or more third parties including, without limitation, relevant rates, prices, yields, yield curves, volatilities, spreads, correlations or other market data in the relevant market; or information of the types described above from internal sources if that information is of the same type used by USBO in the regular course of its business for the valuation of similar transactions. The information may include costs of funding, to the extent costs of funding are not and would not be a component of the other information being utilized. Third parties supplying quotations or market data may include, without limitation, dealers in the relevant markets, end-users of the relevant product, information vendors, brokers and other sources of market information.

In addition, in order to provide updated information relating to USBO for use by investors and market professionals, the NYSE Arca calculates and disseminates throughout the core trading session on each trading day an updated indicative fund value. The indicative fund value is calculated by using the prior day’s closing NAV per unit of USBO as a base and updating that value throughout the trading day to reflect changes in the most recently reported trade price for the active Brent crude oil Futures Contracts on the ICE Futures Exchange. The prices reported for those Futures Contract months are adjusted based on the prior day’s spread differential between settlement values for the relevant contract and the spot month contract. In the event that the spot month contract is also the Benchmark Futures Contract, the last sale price for that contract is not adjusted. The indicative fund value unit basis disseminated during NYSE Arca core trading session hours should not be viewed as an actual real time update of the NAV, because the NAV is calculated only once at the end of each trading day based upon the relevant end of day values of USBO’s investments.

63

The NYSE Arca disseminates the indicative fund value through the facilities of CTA/CQ High Speed Lines. In addition, the indicative fund value is published on the NYSE Arca’s website and is available through on-line information services such as Bloomberg and Reuters.

Dissemination of the indicative fund value provides additional information that is not otherwise available to the public and is useful to investors and market professionals in connection with the trading of USBO units on the NYSE Arca. Investors and market professionals are able throughout the trading day to compare the market price of USBO and the indicative fund value. If the market price of USBO units diverges significantly from the indicative fund value, market professionals will have an incentive to execute arbitrage trades. For example, if USBO appears to be trading at a discount compared to the indicative fund value, a market professional could buy USBO units on the NYSE Arca and sell short futures contracts. Such arbitrage trades can tighten the tracking between the market price of USBO and the indicative fund value and thus can be beneficial to all market participants.

In addition, other Futures Contracts, Other Crude Oil-Related Investments and Treasuries held by USBO are valued by the Administrator, using rates and points received from client-approved third party vendors (such as Reuters and WM Company) and advisor quotes. These investments are not included in the indicative value. The indicative fund value is based on the prior day’s NAV and moves up and down solely according to changes in the Benchmark Futures Contracts.

Creation and Redemption of Units

USBO creates and redeems units from time to time, but only in one or more Creation Baskets or Redemption Baskets. The creation and redemption of baskets are only made in exchange for delivery to USBO or the distribution by USBO of the amount of Treasuries and any cash represented by the baskets being created or redeemed, the amount of which is based on the combined NAV of the number of units included in the baskets being created or redeemed determined after 4:00 p.m. New York time on the day the order to create or redeem baskets is properly received.

Authorized Purchasers are the only persons that may place orders to create and redeem baskets. Authorized Purchasers must be (1)registered broker-dealers or other securities market participants, such as banks and other financial institutions, that are not required to register as broker-dealers to engage in securities transactions described below, and (2) DTC Participants. To become an Authorized Purchaser, a person must enter into an Authorized Purchaser Agreement with the General Partner. The Authorized Purchaser Agreement provides the procedures for the creation and redemption of baskets and for the delivery of the Treasuries and any cash required for such creation and redemptions. The Authorized Purchaser Agreement and the related procedures attached thereto may be amended by USBO, without the consent of any limited partner or unitholder or Authorized Purchaser. Authorized Purchasers pay a transaction fee of $350 to USBO through May 1, 2014 for each order they place to create or redeem one or more baskets; on and after May 2, 2014, the fee increases to $1,000. Authorized Purchasers who make deposits with USBO in exchange for baskets receive no fees, commission or other form of compensation or inducement of any kind from either USBO or the General Partner, and no such person will have any obligation or responsibility to the General Partner or USBO to effect any sale or resale of units.

Certain Authorized Purchasers are expected to be capable of participating directly in the physical crude oil market and the crude oil futures market. In some cases, Authorized Purchasers or their affiliates may from time to time buy or sell crude oil or Crude Oil Interests and may profit in these instances. The General Partner believes that the size and operation of the crude oil market make it unlikely that an Authorized Purchaser’s direct activities in the crude oil or securities markets will significantly affect the price of crude oil, Crude Oil Interests, Futures Contracts, or the price of the units.

Each Authorized Purchaser is required to be registered as a broker-dealer under the Exchange Act and is a member in good standing with FINRA, or exempt from being or otherwise not required to be registered as a broker-dealer or a member of FINRA, and qualified to act as a broker or dealer in the states or other jurisdictions where the nature of its business so requires. Certain Authorized Purchasers may also be regulated under federal and state banking laws and regulations. Each Authorized Purchaser has its own set of rules and procedures, internal controls and information barriers as it determines is appropriate in light of its own regulatory regime.

Under the Authorized Purchaser Agreement, the General Partner has agreed to indemnify the Authorized Purchasers against certain liabilities, including liabilities under the Securities Act of 1933, as amended, and to contribute to the payments the Authorized Purchasers may be required to make in respect of those liabilities.

The following description of the procedures for the creation and redemption of baskets is only a summary and an investor should refer to the relevant provisions of the LP Agreement and the form of Authorized Purchaser Agreement for more detail. The LP Agreement is attached to this prospectus. The form of the AP Agreement is attached as an exhibit to the registration statement of which this prospectus is a part. See “Where You Can Find More Information” for information about where you can obtain the registration statement.

Creation Procedures

On any business day, an Authorized Purchaser may place an order with the Marketing Agent to create one or more baskets. For purposes of processing purchase and redemption orders, a “business day” means any day other than a day when any of the NYSE Arca, the ICE Futures or the NYSE is closed for regular trading. Purchase orders must be placed by 12:00 p.m. New York time or the close of regular trading on the NYSE Arca, whichever is earlier. The day on which the Marketing Agent receives a valid purchase order is referred to as the purchase order date.

By placing a purchase order, an Authorized Purchaser agrees to deposit Treasuries, cash, or a combination of Treasuries and cash with USBO, as described below. Prior to the delivery of baskets for a purchase order, the Authorized Purchaser must also have wired to the Custodian the non-refundable transaction fee due for the purchase order. Authorized Purchasers may not withdraw a creation request.

The manner by which creations are made is dictated by the terms of the Authorized Purchaser Agreement. By placing a purchase order, an Authorized Purchaser agrees to (1) deposit Treasuries, cash, or a combination of Treasuries and cash with the Custodian of the fund, and (2) if required by the General Partner in its sole discretion, enter into or arrange for a block trade, an exchange for physical or exchange for swap, or any other over-the-counter energy transaction (through itself or a designated acceptable broker) with the fund for the purchase of a number and type of futures contracts at the closing settlement price for such contracts on the purchase order date. If an Authorized Purchaser fails to consummate (1) and (2), the order shall be cancelled. The number and types of contracts specified shall be determined by the General Partner, in its sole discretion, to meet USBO’s investment objective and shall be purchased as a result of the Authorized Purchaser’s purchase of units.

Determination of Required Deposits

The total deposit required to create each basket (“Creation Basket Deposit”) is the amount of Treasuries and/or cash that is in the same proportion to the total assets of USBO (net of estimated accrued but unpaid fees, expenses and other liabilities) on the purchase order date is accepted as the number of units to be created under the purchase order is in proportion to the total number of units outstanding on the purchase order date. The General Partner determines, directly in its sole discretion or in consultation with the Administrator, the requirements for Treasuries and the amount of cash, including the maximum permitted remaining maturity of a Treasury and proportions of Treasury and cash that may be included in deposits to create baskets. The Marketing Agent will publish such requirements at the beginning of each business day. The amount of cash deposit required is the difference between the aggregate market value of the Treasuries required to be included in a Creation Basket Deposit as of 4:00 p.m. New York time on the date the order to purchase is properly received and the total required deposit.

Delivery of Required Deposits

An Authorized Purchaser who places a purchase order is responsible for transferring to USBO’s account with the Custodian the required amount of Treasuries and cash by the end of the third business day following the purchase order date. Upon receipt of the deposit amount, the Administrator directs DTC to credit the number of baskets ordered to the Authorized Purchaser’s DTC account on the third business day following the purchase order date. The expense and risk of delivery and ownership of Treasuries until such Treasuries have been received by the Custodian on behalf of USBO is borne solely by the Authorized Purchaser.

Because orders to purchase baskets must be placed by 12:00 p.m., New York time, but the total payment required to create a basket during the continuous offering period will not be determined until after 4:00 p.m. New York time on the date the purchase order is received, Authorized Purchasers will not know the total amount of the payment required to create a basket at the time they submit an irrevocable purchase order for the basket. USBO’s NAV and the total amount of the payment required to create a basket could rise or fall substantially between the time an irrevocable purchase order is submitted and the time the amount of the purchase price in respect thereof is determined.

65

Rejection of Purchase Orders

The General Partner acting by itself or through the Marketing Agent shall have the absolute right but no obligation to reject a purchase order or a Creation Basket Deposit if:

• it determines that the investment alternative available to USBO at that time will not enable it to meet its investment objective;

• it determines that the purchase order or the Creation Basket Deposit is not in proper form;

• it believes that the purchase order or the Creation Basket Deposit would have adverse tax consequences to USBO, the limited partners or the unitholders;

• the acceptance or receipt of the Creation Basket Deposit would, in the opinion of counsel to the General Partner, be unlawful; or

• circumstances outside the control of the General Partner, Marketing Agent or Custodian make it, for all practical purposes, not feasible to process creations of baskets.

None of the General Partner, Marketing Agent or Custodian will be liable for the rejection of any purchase order or Creation Basket Deposit.

Redemption Procedures

The procedures by which an Authorized Purchaser can redeem one or more baskets mirror the procedures for the creation of baskets. On any business day, an Authorized Purchaser may place an order with the Marketing Agent to redeem one or more baskets. Redemption orders must be placed by 12:00 p.m. New York time or the close of regular trading on the NYSE, whichever is earlier. A redemption order so received will be effective on the date it is received in satisfactory form by the Marketing Agent. The redemption procedures allow Authorized Purchasers to redeem baskets and do not entitle an individual unitholder to redeem any units in an amount less than a Redemption Basket, or to redeem baskets other than through an Authorized Purchaser.

By placing a redemption order, an Authorized Purchaser agrees to deliver the baskets to be redeemed through DTC’s book-entry system to USBO not later than 3:00 p.m. New York time on the third business day following the effective date of the redemption order. Prior to the delivery of the redemption distribution for a redemption order, the Authorized Purchaser must also have wired to USBO’s account at the Custodian the non-refundable transaction fee due for the redemption order. An Authorized Purchaser may not withdraw a redemption order.

The manner by which redemptions are made is dictated by the terms of the Authorized Purchaser Agreement. By placing a redemption order, an Authorized Purchaser agrees to (1) deliver the Redemption Basket to be redeemed through DTC’s book-entry system to USBO’s account with the Custodian not later than 3:00 p.m. New York time on the third business day following the effective date of the redemption order (“Redemption Distribution Date”), and (2) if required by the General Partner in its sole discretion, enter into or arrange for a block trade, an exchange for physical or exchange for swap, or any other over-the-counter energy transaction (through itself or a designated acceptable broker) with the fund for the sale of a number and type of futures contracts at the closing settlement price for such contracts on the Redemption Order Date. If an Authorized Purchaser fails to consummate (1) and (2) above, the order shall be cancelled. The number and type of contracts specified shall be determined by the General Partner, in its sole discretion, to meet USBO’s investment objective and shall be sold as a result of the Authorized Purchaser’s sale of units.

Determination of Redemption Distribution

The redemption distribution from USBO consists of a transfer to the redeeming Authorized Purchaser of an amount of Treasuries and cash that is in the same proportion to the total assets of USBO (net of estimated accrued but unpaid fees, expenses and other liabilities) on the date the order to redeem is properly received as the number of units to be redeemed under the redemption order is in proportion to the total number of units outstanding on the date the order is received. The General Partner, directly or in consultation with the Administrator, determines the requirements for Treasuries and the amounts of cash, including the maximum permitted remaining maturity of a Treasury, and the proportions of Treasuries and cash that may be included in distributions to redeem baskets. The Marketing Agent will publish an estimate of the redemption distribution per basket as of the beginning of each business day.

66

Delivery of Redemption Distribution

The redemption distribution due from USBO will be delivered to the Authorized Purchaser by 3:00 p.m. New York time on the third business day following the redemption order date if, by 3:00 p.m. New York time on such third business day, USBO’s DTC account has been credited with the baskets to be redeemed. If USBO’s DTC account has not been credited with all of the baskets to be redeemed by such time, the redemption distribution will be delivered to the extent of whole baskets received. Any remainder of the redemption distribution will be delivered on the next business day to the extent of remaining whole baskets received if USBO receives the fee applicable to the extension of the redemption distribution date which the General Partner may, from time to time, determine and the remaining baskets to be redeemed are credited to USBO’s DTC account by 3:00 p.m. New York time on such next business day. Any further outstanding amount of the redemption order shall be cancelled. Pursuant to information from the General Partner, the Custodian will also be authorized to deliver the redemption distribution notwithstanding that the baskets to be redeemed are not credited to USBO’s DTC account by 3:00 p.m. New York time on the third business day following the redemption order date if the Authorized Purchaser has collateralized its obligation to deliver the baskets through DTC’s book entry-system on such terms as the General Partner may from time to time determine.

Suspension or Rejection of Redemption Orders

The General Partner may, in its discretion, suspend the right of redemption, or postpone the redemption settlement date, (1) for any period during which the NYSE Arca or the ICE Futures is closed other than customary weekend or holiday closings, or trading on the NYSE Arca or the ICE Futures is suspended or restricted, (2) for any period during which an emergency exists as a result of which delivery, disposal or evaluation of Treasuries is not reasonably practicable, or (3) for such other period as the General Partner determines to be necessary for the protection of the limited partners. For example, the General Partner may determine that it is necessary to suspend redemptions to allow for the orderly liquidation of USBO’s assets at an appropriate value to fund a redemption. If the General Partner has difficulty liquidating its positions, e.g., because of a market disruption event in the futures markets, a suspension of trading by the exchange where the futures contracts are listed or an unanticipated delay in the liquidation of a position in an over-the-counter contract, it may be appropriate to suspend redemptions until such time as such circumstances are rectified. None of the General Partner, the Marketing Agent, the Administrator, or the Custodian will be liable to any person or in any way for any loss or damages that may result from any such suspension or postponement.

Redemption orders must be made in whole baskets. The General Partner will reject a redemption order if the order is not in proper form as described in the Authorized Purchaser Agreement or if the fulfillment of the order, in the opinion of its counsel, might be unlawful. The General Partner may also reject a redemption order if the number of units being redeemed would reduce the remaining outstanding units to 100,000 units (i.e., two baskets) or less.

Creation and Redemption Transaction Fee

To compensate USBO for its expenses in connection with the creation and redemption of baskets, an Authorized Purchaser is required to pay a transaction fee to USBO of $350 per order through May 1, 2014 to create or redeem baskets, regardless of the number of baskets in such order; on and after May 2, 2014, the fee increases to $1,000. The transaction fee may be reduced, increased or otherwise changed by the General Partner. The General Partner shall notify DTC of any change in the transaction fee and will not implement any increase in the fee for the redemption of baskets until 30 days after the date of notice.

Tax Responsibility

Authorized Purchasers are responsible for any transfer tax, sales or use tax, stamp tax, recording tax, value added tax or similar tax or governmental charge applicable to the creation or redemption of baskets, regardless of whether or not such tax or charge is imposed directly on the Authorized Purchaser, and agree to indemnify the General Partner and USBO if they are required by law to pay any such tax, together with any applicable penalties, additions to tax and interest thereon.

Secondary Market Transactions

As noted, USBO creates and redeems units from time to time, but only in one or more Creation Baskets or Redemption Baskets. The creation and redemption of baskets are only made in exchange for delivery to USBO or the distribution by USBO of the amount of Treasuries and cash represented by the baskets being created or redeemed, the amount of which will be based on the aggregate NAV of the number of units included in the baskets being created or redeemed determined on the day the order to create or redeem baskets is properly received.

67

As discussed above, Authorized Purchasers are the only persons that may place orders to create and redeem baskets. Authorized Purchasers must be registered broker-dealers or other securities market participants, such as banks and other financial institutions that are not required to register as broker-dealers to engage in securities transactions. An Authorized Purchaser is under no obligation to create or redeem baskets, and an Authorized Purchaser is under no obligation to offer to the public units of any baskets it does create. Authorized Purchasers that do offer to the public units from the baskets they create will do so at per-unit offering prices that are expected to reflect, among other factors, the trading price of the units on the NYSE Arca, the NAV of USBO at the time the Authorized Purchaser purchased the Creation Baskets and the NAV of the units at the time of the offer of the units to the public, the supply of and demand for units at the time of sale, and the liquidity of the Futures Contract market and the market for Other Crude Oil-Related Investments. The prices of units offered by Authorized Purchasers are expected to fall between USBO’s NAV and the trading price of the units on the NYSE Arca at the time of sale. Units initially comprising the same basket but offered by Authorized Purchasers to the public at different times may have different offering prices. An order for one or more baskets may be placed by an Authorized Purchaser on behalf of multiple clients. Authorized Purchasers who make deposits with USBO in exchange for baskets receive no fees, commissions or other form of compensation or inducement of any kind from either USBO or the General Partner, and no such person has any obligation or responsibility to the General Partner or USBO to effect any sale or resale of units. Units trade in the secondary market on the NYSE Arca. Units may trade in the secondary market at prices that are lower or higher relative to their NAV per unit. The amount of the discount or premium in the trading price relative to the NAV per unit may be influenced by various factors, including the number of investors who seek to purchase or sell units in the secondary market and the liquidity of the Futures Contracts market and the market for Other Crude Oil-Related Investments. While the units trade during the core trading session on the NYSE Arca until 4:00 p.m. New York time and trading in Futures Contracts on the ICE Futures Exchange continues throughout the entire NYSE Arca trading day, liquidity in the market for Futures Contracts and Other Crude Oil-Related Investments traded on the NYMEX may be reduced after the close of the NYMEX at 2:30 p.m. New York time. As a result, during this time, particularly if USBO has invested in Futures Contracts and Other Crude Oil-Related Investment traded on NYMEX, trading spreads, and the resulting premium or discount, on the units may widen.

Use of Proceeds

The General Partner causes USBO to transfer the proceeds from the sale of Creation Baskets to the Custodian or other custodian for trading activities. The General Partner will invest USBO’s Futures Contracts and Other Crude Oil-Related Investments and investments in Treasuries, cash and/or cash equivalents. When USBO purchases a Futures Contract and certain exchange-traded Other Crude Oil-Related Investments, USBO is required to deposit 5% to 30% with the selling futures commission merchant on behalf of the exchange a portion of the value of the contract or other interest as security to ensure payment for the obligation under Crude Oil-Related Interests at maturity. This deposit is known as initial margin. Counterparties in transactions in over-the-counter Crude Oil-Related Interests will generally impose similar collateral requirements on USBO. The General Partner will invest the assets that remain after margin and collateral are posted in Treasuries, cash and/or cash equivalents subject to these margin and collateral requirements. The General Partner has sole authority to determine the percentage of assets that are:

• held on deposit with the futures commission merchant or other custodian;

• used for other investments; and

• held in bank accounts to pay current obligations and as reserves.

Ongoing margin and collateral payments will generally be required for both exchange-traded and over-the-counter Crude Oil-Related Interests based on changes in the value of the Crude Oil-Related Interests. Furthermore, ongoing collateral requirements with respect to over-the-counter Crude Oil-Related Interests are negotiated by the parties, and may be affected by overall market volatility, volatility of the underlying commodity or index, the ability of the counterparty to hedge its exposure under the Crude Oil-Related Interest, and each party’s creditworthiness. In light of the differing requirements for initial payments under exchange-traded and over-the-counter Crude Oil-Related Interests and the fluctuating nature of ongoing margin and collateral payments, it is not possible to estimate what portion of USBO’s assets will be posted as margin or collateral at any given time. The Treasuries, cash and cash equivalents held by USBO will constitute reserves that will be available to meet ongoing margin and collateral requirements. All interest income will be used for USBO’s benefit. The General Partner invests the balance of USBO’s assets not invested in Crude Oil-Related Interests or held in margin as reserves to be available for changes in margin.

A futures commission merchant, counterparty, government agency or commodity exchange could increase margin or collateral requirements applicable to USBO to hold trading positions at any time. Moreover, margin is merely a security deposit and has no bearing on the profit or loss potential for any positions held.

The assets of USBO posted as margin for Futures Contracts and over-the-counter contracts will be held in segregation pursuant to the CEA and CFTC regulations.

Limited Partnership Agreement

The following paragraphs are a summary of certain provisions of our LP Agreement. The following discussion is qualified in its entirety by reference to our LP Agreement.

68

Authority of the General Partner

Our General Partner is generally authorized to perform all acts deemed necessary to carry out the purposes of the limited partnership and to conduct our business. Our partnership existence will continue into perpetuity, until terminated in accordance with our LP Agreement. Our General Partner has a power of attorney to take certain actions, including the execution and filing of documents, on our behalf and with respect to our LP Agreement. However, our partnership agreement limits the authority of our General Partner as follows:

• Other than in connection with the issuance or redemption of units, or upon termination of the partnership as contemplated by the LP Agreement, the General Partner may not sell, exchange or otherwise dispose of all or substantially all of the partnership’s assets in a single transaction or a series of related transactions (including by way of merger, consolidation or other combination with any other person) or approve on behalf of the partnership, the sale, exchange or other disposition of all or substantially all of the assets of all of the partnership, taken as a whole, without the approval of at least a majority of the limited partners; provided, however, that this provision shall not preclude or limit the General Partner’s ability to mortgage, pledge, hypothecate or grant a security interest in all or substantially all of the partnership’s assets and shall not apply to any forced sale of any or all of the partnership’s assets pursuant to the foreclosure of, or other realization upon, any such encumbrance.

• The General Partner is not authorized to institute or initiate on behalf of, or otherwise cause, the partnership to (a) make a general assignment for the benefit of creditors; (b) file a voluntary bankruptcy petition; or (c) file a petition seeking for the partnership a reorganization, arrangement, composition, readjustment liquidation, dissolution or similar relief under any law.

• The General Partner may not, without written approval of the specific act by all of the limited partners or by other written instrument executed and delivered by all of the limited partners subsequent to the date of the LP Agreement, take any action in contravention of the LP Agreement, including, without limitation, (i) any act that would make it impossible to carry on the ordinary business of the partnership, except as otherwise provided in the LP Agreement; (ii) possess partnership property, or assign any rights in specific partnership property, for other than a partnership purpose; (iii) admit a person as a partner, except as otherwise provided in the LP Agreement; (iv) amend the LP Agreement in any manner, except as otherwise provided in the LP Agreement or applicable law; or (v) transfer its interest as General Partner of the partnership, except as otherwise provided in the LP Agreement.

• In general, unless approved by a majority of the limited partners, our General Partner shall not take any action, or refuse to take any reasonable action, the effect of which would be to cause us, to the extent it would materially and adversely affect limited partners, to be taxable as a corporation or to be treated as an association taxable as a corporation for federal income tax purposes.

Withdrawal or Removal of The General Partner

The General Partner shall be deemed to have withdrawn from the partnership upon the occurrence of any one of the following events:

• the General Partner voluntarily withdraws from the partnership by giving written notice to the other partners;

• the General Partner transfers all of its rights as General Partner;

• the General Partner is removed;

• the General Partner (A) makes a general assignment for the benefit of creditors; (B) files a voluntary bankruptcy petition; (C) files a petition or answer seeking for itself a reorganization, arrangement, composition, readjustment liquidation, dissolution or similar relief under any law; (D) files an answer or other pleading admitting or failing to contest the material allegations of a petition filed against the General Partner in a proceeding of the type described in clauses (A) – (C) of this sentence; or (E) seeks, consents to or acquiesces in the appointment of a trustee, receiver or liquidator of the General Partner or of all or any substantial part of its properties;

• a final and non-appealable judgment is entered by a court with appropriate jurisdiction ruling that the General Partner is bankrupt or insolvent or a final and non-appealable order for relief is entered by a court with appropriate jurisdiction against the General Partner, in each case under any federal or state bankruptcy or insolvency laws as now or hereafter in effect; or

• a certificate of dissolution or its equivalent is filed for the General Partner, or 90 days expire after the date of notice to the General Partner of revocation of its charter without a reinstatement of its charter, under the laws of its state of incorporation.

The General Partner may be removed with or without cause if such removal is approved by the holders of at least 66 2/3% of the outstanding units (excluding for this purpose units held by the General Partner and its affiliates).

69

Meetings

All acts of the limited partners should be done in accordance with the Delaware Revised Uniform Limited Partnership Act (“DRULPA”). Upon the written request of 20% or more in interest of the limited partners, the General Partner may, but is not required to, call a meeting of the limited partners. Notice of such meeting shall be given within 30 days after, and the meeting shall be held within 60 days after, receipt of such request. The General Partner may also call a meeting not less than 20 and not more than 60 days prior to the meeting. Any such notice shall state briefly the purpose of the meeting, which shall be held at a reasonable time and place. Any limited partner may obtain a list of names, addresses, and interests of the limited partners upon written request to the General Partner.

Limited Liability

Assuming that a limited partner does not take part in the control of our business, and that he otherwise acts in conformity with the provisions of our LP Agreement, his liability under Delaware law will be limited, subject to certain possible exceptions, generally to the amount of capital he is obligated to contribute to us in respect of his units or other limited partner interests plus his share of any of our undistributed profits and assets. In light of the fact that a limited partner’s liability may extend beyond his capital contributions, a limited partner may lose more money than he contributed.

Under Delaware law, a limited partner might be held liable for USBO’s obligations as if it were a General Partner if the limited partner participates in the control of the partnership’s business and the persons who transact business with the partnership think the limited partner is the General Partner.

Under the LP Agreement, a limited partner will not be liable for assessments in addition to its initial capital investment in any of USBO’s capital securities representing limited partnership interests. However, a limited partner still may be required to repay to USBO any amounts wrongfully returned or distributed to it under some circumstances. Under Delaware law, USBO may not make a distribution to limited partners if the distribution causes USBO’s liabilities (other than liabilities to partners on account of their partnership interests and nonrecourse liabilities) to exceed the fair value of USBO’s assets. Delaware law provides that a limited partner who receives such a distribution and knew at the time of the distribution that the distribution violated the law will be liable to the limited partnership for the amount of the distribution for three years from the date of the distribution.

The General Partner Has Conflicts of Interest

There are present and potential future conflicts of interest in USBO’s structure and operation you should consider before you purchase units. The General Partner will use this notice of conflicts as a defense against any claim or other proceeding made. If the General Partner is not able to resolve these conflicts of interest adequately, it may impact USBO’s and the Related Public Funds’ ability to achieve their investment objectives.

USBO and the General Partner may have inherent conflicts to the extent the General Partner attempts to maintain USBO’s asset size in order to preserve its fee income and this may not always be consistent with USBO’s objective of having the value of its unit’s NAV track changes in the price of the Benchmark Future Contract.

The General Partner’s officers, directors and employees, do not devote their time exclusively to USBO. These persons are directors, officers or employees of other entities which may compete with USBO for their services. They could have a conflict between their responsibilities to USBO and to those other entities. The General Partner believes that it has sufficient personnel, time, and working capital to discharge its responsibilities in a fair manner and that these persons’ conflicts should not impair their ability to provide services to USBO.

The General Partner and the General Partner’s principals, officers, directors and employees may trade futures and related contracts for their own account. Limited partners and other unitholders are not permitted to inspect the trading records or any written policies related to such trading of the General Partner and its principals, officers, directors, and employees. A conflict of interest may exist if their trades are in the same markets and at the same time as USBO trades using the clearing broker to be used by USBO. A potential conflict also may occur when the General Partner’s principals trade their accounts more aggressively or take positions in their accounts which are opposite, or ahead of, the positions taken by USBO. The General Partner has adopted a Code of Business Conduct and Ethics to ensure that the officers, directors, and employees of the General Partner and its affiliates do not engage in trades that will harm the fund or the unitholders. The General Partner has also adopted Corporate Governance Guidelines. If these provisions are not successful, unitholders may be harmed in that such trades could affect the prices of the futures contracts purchased by USBO which could affect USBO’s ability to track the Benchmark Futures Contract. The Code of Business Conduct and Ethics, and the Corporate Governance Guidelines may be found on USBO’s website at www.unitedstatesbrentoilfund.com.

70

The General Partner has sole current authority to manage the investments and operations of USBO, and this may allow it to act in a way that furthers its own interests which may create a conflict with your best interests. Limited partners have limited voting control, which will limit their ability to influence matters such as amendment of the LP Agreement, change in USBO’s basic investment policy, dissolution of USBO, or the sale or distribution of USBO’s assets.

The General Partner serves as the general partner to USBO and the Related Public Funds, as well as of other funds that have yet to offer securities to the public or begin operations. The General Partner may have a conflict to the extent that its trading decisions for USBO may be influenced by the effect they would have on the other funds it manages. By way of example, if, as a result of reaching position limits imposed by the ICE Futures Exchange on Brent Crude Oil Futures Contracts (or otherwise), the General Partner might determine that there would be potential benefits in purchasing instead another type of petroleum-based futures contract, such as gasoline futures contracts. However, the General Partner might be disinclined to purchase gasoline futures contracts, this decision could impact its ability to purchase additional gasoline futures contracts for USBO if adversely doing so would be due to applicability position limits for other Related Public Funds (such as the United States Gasoline Fund, LP). In addition, the General Partner is required to indemnify the officers and directors of the other funds, if the need for indemnification arises. This potential indemnification will cause the General Partner’s assets to decrease. If the General Partner’s other sources of income are not sufficient to compensate for the indemnification, then the General Partner may terminate and you could lose your investment.

No Resolution of Conflicts Procedures

Whenever a conflict of interest exists or arises between the General Partner on the one hand, and the partnership or any limited partner, on the other hand, any resolution or course of action by the General Partner in respect of such conflict of interest shall be permitted and deemed approved by all partners and shall not constitute a breach of the LP Agreement or of any agreement contemplated hereby or of a duty stated or implied by law or equity, if the resolution or course of action is, or by operation of the LP Agreement is deemed to be, fair and reasonable to the partnership. If a dispute arises, under the LP Agreement it will be resolved either through negotiations with the General Partner or by courts located in the State of Delaware.

Under the LP Agreement, any resolution is deemed to be fair and reasonable to the partnership if the resolution is:

• approved by the audit committee, although no party is obligated to seek approval and the General Partner may adopt a resolution or course of action that has not received approval;

• on terms no less favorable to the limited partners than those generally being provided to or available from unrelated third parties; or

• fair to the limited partners, taking into account the totality of the relationships of the parties involved including other transactions that may be particularly favorable or advantageous to the limited partners.

The previous risk factors and conflicts of interest are complete as of the date of this prospectus; however, additional risks and conflicts may occur which are not presently foreseen by the General Partner. You may not construe this prospectus as legal or tax advice. Before making an investment in this fund, you should read this entire prospectus, including the LP Agreement (Appendix B). You should also consult with your personal legal, tax, and other professional advisors.

Interests of Named Experts and Counsel

The General Partner has engaged Reed Smith LLP to assist in the preparation of this prospectus. Neither the law firm nor any other expert hired by USBO to give advice on the preparation of this offering document has been hired on a contingent fee basis. Nor does any of them have any present or future expectation of interest in the General Partner, Marketing Agent, Authorized Purchasers, Custodian, Administrator or other service providers to USBO.

The General Partner’s Responsibilities and Remedies

Pursuant to the DRULPA, parties may contractually modify or even eliminate fiduciary duties in a limited partnership agreement to the limited partnership itself, or to another partner or person otherwise bound by the limited partnership agreement. Parties may not, however, eliminate the implied covenant of good faith and fair dealing. Where parties unambiguously provide for fiduciary duties in a limited partnership agreement, those expressed duties become the standard that courts will use to determine whether such duties were breached. For this reason, USBO’s limited partnership agreement does not explicitly provide for any fiduciary duties so that common law fiduciary duty principles will apply to measure the General Partner’s conduct.

71

A prospective investor should be aware that the General Partner has a responsibility to limited partners of USBO to exercise good faith and fairness in all dealings. The fiduciary responsibility of a general partner to limited partners is a developing and changing area of the law and limited partners who have questions concerning the duties of the General Partner should consult with their counsel. In the event that a limited partner of USBO believes that the General Partner has violated its fiduciary duty to the limited partners, he may seek legal relief individually or on behalf of USBO under applicable laws, including under DRULPA and under commodities laws, to recover damages from or require an accounting by the General Partner. Limited partners may also have the right, subject to applicable procedural and jurisdictional requirements, to bring class actions in federal court to enforce their rights under the federal securities laws and the rules and regulations promulgated thereunder by the SEC. Limited partners who have suffered losses in connection with the purchase or sale of the units may be able to recover such losses from the General Partner where the losses result from a violation by the General Partner of the federal securities laws. State securities laws may also provide certain remedies to limited partners. Limited partners should be aware that performance by the General Partner of its fiduciary duty is measured by the terms of the LP Agreement as well as applicable law. Limited partners are afforded certain rights to institute reparations proceedings under the CEA for violations of the CEA or of any rule, regulation or order of the CFTC by the General Partner.

Liability and Indemnification

Under the LP Agreement, neither a General Partner nor any employee or other agent of USBO nor any officer, director, stockholder, partner, employee or agent of a General Partner (a “Protected Person”) shall be liable to any partner or USBO for any mistake of judgment or for any action or inaction taken, nor for any losses due to any mistake of judgment or to any action or inaction or to the negligence, dishonesty or bad faith of any officer, director, stockholder, partner, employee, agent of USBO or any officer, director, stockholder, partner, employee or agent of such General Partner, provided that such officer, director, stockholder, partner, employee, or agent of the partner or officer, director, stockholder, partner, employee or agent of such General Partner was selected, engaged or retained by such General Partner with reasonable care, except with respect to any matter as to which such General Partner shall have been finally adjudicated in any action, suit or other proceeding not to have acted in good faith in the reasonable belief that such Protected Person’s action was in the best interests of USBO and except that no Protected Person shall be relieved of any liability to which such Protected Person would otherwise be subject by reason of willful misfeasance, gross negligence or reckless disregard of the duties involved in the conduct of the Protected Person’s office.

USBO shall, to the fullest extent permitted by law, but only out of USBO assets, indemnify and hold harmless a General Partner and each officer, director, stockholder, partner, employee or agent thereof (including persons who serve at USBO’s request as directors, officers or trustees of another organization in which USBO has an interest as a unitholder, creditor or otherwise) and their respective Legal Representatives and successors (hereinafter referred to as a “Covered Person” against all liabilities and expenses, including but not limited to amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and counsel fees reasonably incurred by any Covered Person in connection with the defense or disposition of any action, suit or other proceedings, whether civil or criminal, before any court or administrative or legislative body, in which such Covered Person may be or may have been involved as a party or otherwise or with which such person may be or may have been threatened, while in office or thereafter, by reason of an alleged act or omission as a General Partner or director or officer thereof, or by reason of its being or having been such a General Partner, director or officer, except with respect to any matter as to which such Covered Person shall have been finally adjudicated in any such action, suit or other proceeding not to have acted in good faith in the reasonable belief that such Covered Person’s action was in the best interest of USBO, and except that no Covered Person shall be indemnified against any liability to USBO or limited partners to which such Covered Person would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person’s office. Expenses, including counsel fees so incurred by any such Covered Person, may be paid from time to time by USBO in advance of the final disposition of any such action, suit or proceeding on the condition that the amounts so paid shall be repaid to USBO if it is ultimately determined that the indemnification of such expenses is not authorized hereunder.

Provisions of Law

According to applicable law, indemnification of the General Partner is payable only if the General Partner determined, in good faith, that the act, omission or conduct that gave rise to the claim for indemnification was in the best interest of USBO and the act, omission or activity that was the basis for such loss, liability, damage, cost or expense was not the result of negligence or misconduct and such liability or loss was not the result of negligence or misconduct by the General Partner, and such indemnification or agreement to hold harmless is recoverable only out of the assets of USBO and not from the members, individually.

Provisions of Federal and State Securities Laws

This offering is made pursuant to federal and state securities laws. The SEC and state securities agencies take the position that indemnification of the General Partner that arises out of an alleged violation of such laws is prohibited unless certain conditions are met.

Those conditions require that no indemnification of the General Partner or any underwriter for USBO may be made in respect of any losses, liabilities or expenses arising from or out of an alleged violation of federal or state securities laws unless: (i) there has been a successful adjudication on the merits of each count involving alleged securities law violations as to the party seeking indemnification and the court approves the indemnification; (ii) such claim has been dismissed with prejudice on the merits by a court of competent jurisdiction as to the party seeking indemnification; or (iii) a court of competent jurisdiction approves a settlement of the claims against the party seeking indemnification and finds that indemnification of the settlement and related costs should be made, provided that, before seeking such approval, the General Partner or other indemnitee must apprise the court of the position held by regulatory agencies against such indemnification. These agencies are the SEC and the securities administrator of the State or States in which the plaintiffs claim they were offered or sold membership interests.

72

Provisions of the Securities Act of 1933 and NASAA Guidelines

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to the General Partner or its directors, officers, or persons controlling USBO, USBO has been informed that SEC and the various State administrators believe that such indemnification is against public policy as expressed in the Securities Act of 1933 and the North American Securities Administrators Association, Inc. (“NASAA”) commodity pool guidelines and is therefore unenforceable.

Books and Records

USBO keeps its books of record and account at its office located at 1999 Harrison Street, Suite 1530, Oakland, California 94612 or at the offices of the Administrator at its office located at 40 Water Street, Boston, Massachusetts, 02109, or such office, including of an administrative agent, as it may subsequently designate upon notice. These books and records are open to inspection by any person who establishes to USBO’s satisfaction that such person is a limited partner upon reasonable advance notice at all reasonable times during the usual business hours of USBO.

USBO keeps a copy of USBO’s LP Agreement on file in its office which is available for inspection on reasonable advance notice at all reasonable times during its usual business hours by any limited partner.

Analysis of Critical Accounting Policies

USBO’s critical accounting policies are forth in the financial statements that are incorporated by reference in this prospectus are prepared in accordance with accounting principles generally accepted in the United States of America, which require the use of certain accounting policies that affect the amounts reported in these financial statements, including the following: USBO trades are accounted for on a trade-date basis and marked to market on a daily basis. The difference between their cost and market value is recorded as “change in unrealized profit/loss” for open (unrealized) contracts, and recorded as “realized profit/loss” when open positions are closed out; the sum of these amounts constitutes USBO’s trading revenues. Earned interest income revenue, as well as management fee, and brokerage fee expenses of USBO are recorded on an accrual basis. The General Partner believes that all relevant accounting assumptions and policies have been considered.

Statements, Filings, and Reports

At the end of each fiscal year, USBO will furnish to DTC Participants for distribution to each person who is a unitholder at the end of the fiscal year an annual report containing USBO’s audited financial statements and other information about USBO. The General Partner is responsible for the registration and qualification of the units under the federal securities laws and federal commodities laws and any other securities and blue sky laws of the United States or any other jurisdiction as the General Partner may select. The General Partner is responsible for preparing all reports required by the SEC, CFTC, and the NYSE Arca but has entered into an agreement with the Administrator to prepare these reports as required by the SEC, CFTC and the NYSE Arca on USBO’s behalf.

The financial statements of USBO will be audited, as required by law and as may be directed by the General Partner, by an independent registered public accounting firm designated from time to time by the General Partner. The accountants report will be furnished by USBO to unitholders upon request. USBO will make such elections, file such tax returns, and prepare, disseminate and file such tax reports, as it is advised by its counsel or accountants are from time to time required by any applicable statute, rule or regulation.

Reports to Limited Partners

In addition to periodic reports filed with the SEC, including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, all of which can be accessed on the SEC’s website at www.sec.gov or on USBO’s website at www.unitedstatesbrentoilfund.com, USBO, pursuant to the LP Agreement, will provide the following reports to limited partners in the manner prescribed below.

Annual Reports. Within 90 days after the end of each fiscal year, the General Partner shall cause to be delivered to each limited partner who was a limited partner at any time during the fiscal year, an annual report containing the following:

(i) financial statements of the partnership, including, without limitation, a balance sheet as of the end of the partnership’s fiscal year and statements of income, partners’ equity and changes in financial position, for such fiscal year, which shall be prepared in accordance with accounting principles generally accepted in the United States of America consistently applied and shall be audited by a firm of independent certified public accountants registered with the Public Company Accounting Oversight Board;

73

(ii) a general description of the activities of the partnership during the period covered by the report; and

(iii) a report of any material transactions between the partnership and the General Partner or any of its affiliates, including fees or compensation paid by the partnership and the services performed by the General Partner or any such affiliate for such fees or compensation.

Quarterly Reports. Within 45 days after the end of each quarter of each fiscal year, the General Partner shall cause to be delivered to each limited partner who was a limited partner at any time during the quarter then ended, a quarterly report containing a balance sheet and statement of income for the period covered by the report, each of which may be unaudited but shall be certified by the General Partner as fairly presenting the financial position and results of operations of the partnership during the period covered by the report. The report shall also contain a description of any material event regarding the business of the partnership during the period covered by the report.

Monthly Reports. Within 30 days after the end of each month, the General Partner shall cause to be posted on its website and upon request, to be delivered to each limited partner who was a limited partner at any time during the month then ended, a monthly report containing an account statement, which will include a statement of income (loss) and a statement of changes in NAV, for the prescribed period. In addition, the account statement will disclose any material business dealings between the partnership, General Partner, commodity trading advisor (if any), futures commission merchant, or the principals thereof that previously have not been disclosed in this prospectus or any amendment thereto, other account statements or annual reports.

USBO will provide information to its unitholders to the extent required by applicable SEC, CFTC, and NYSE Arca requirements. An issuer, such as USBO, of exchange-traded securities may not always readily know the identities of the investors who own those securities. USBO will post the same information that would otherwise be provided in USBO’s reports to limited partners described above including its monthly account statements, which will include, without limitation, USBO’s NAV, on USBO’s website www.unitedstatesbrentoilfund.com.

Fiscal Year

The fiscal year of USBO is the calendar year. The General Partner may select an alternate fiscal year.

Governing Law; Consent to Delaware Jurisdiction

The rights of the General Partner, USBO, DTC (as registered owner of USBO’s global certificate for units) and the unitholders, are governed by the laws of the State of Delaware. The General Partner, USBO and DTC and, by accepting units, each DTC Participant and each unitholder, consent to the jurisdiction of the courts of the State of Delaware and any federal courts located in Delaware. Such consent is not required for any person to assert a claim of Delaware jurisdiction over the General Partner or USBO.

Security Ownership of Principal Unitholders and Management

None of the directors or executive officers of the General Partner, nor the employees of USBO own any units of USBO. In addition, USBO is not aware of any 5% holder of its units.

Legal Matters

Litigation and Claims

Within the past 5 years of the date of this prospectus, there have been no material administrative, civil or criminal actions against the General Partner, underwriter, or any principal or affiliate of either of them. This includes any actions pending, on appeal, concluded, threatened, or otherwise known to them.

U.S. Federal Income Tax Considerations

The following discussion summarizes the material U.S. federal income tax consequences of the purchase, ownership and disposition of units in USBO, and the U.S. federal income tax treatment of USBO, as of the date hereof. This discussion is applicable to a beneficial owner of units who purchases units in the offering to which this prospectus relates, including a beneficial owner who purchases units from an Authorized Purchaser. Except where noted otherwise, it deals only with units held as capital assets and does not deal with special situations, such as those of dealers in securities or currencies, financial institutions, tax-exempt entities, insurance companies, persons holding units as a part of a position in a “straddle” or as part of a “hedging,” “conversion” or other integrated transaction for U.S. federal income tax purposes, traders in securities or commodities that elect to use a mark-to-market method of accounting, or holders of units whose “functional currency” is not the U.S. dollar. Furthermore, the discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and regulations (“Treasury Regulations”), rulings and judicial decisions thereunder as of the date hereof, and such authorities may be repealed, revoked or modified so as to result in U.S. federal income tax consequences different from those discussed below.

Persons considering the purchase, ownership or disposition of units should consult their own tax advisors concerning the U.S. federal income tax consequences in light of their particular situations as well as any consequences arising under the laws of any other taxing jurisdiction. As used herein, a “U.S. unitholder” of a unit means a beneficial owner of a unit that is, for U.S. federal income tax purposes, (i) a citizen or resident of the United States, (ii) a corporation or partnership created or organized in or under the laws of the United States or any political subdivision thereof, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source or (iv) a trust (X) that is subject to the supervision of a court within the United States and the control of one or more United States persons as described in section 7701(a)(30) of the Code or (Y) that has a valid election in effect under applicable Treasury Regulations to be treated as a United States person. A “Non-U.S. unitholder” is a holder that is not a U.S. unitholder. If a partnership holds our units, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our units, you should consult your own tax advisor regarding the tax consequences.

The General Partner of USBO has received the opinion of Reed Smith LLP, counsel to USBO, that the material U.S. federal income tax consequences to USBO and to U.S. unitholders and Non-U.S. unitholders will be as described below. In rendering its opinion, Reed Smith LLP has relied on the facts described in this prospectus as well as certain factual representations made by USBO and the General Partner. The opinion of Reed Smith LLP is not binding on the Internal Revenue Service (“IRS”), and as a result, the IRS may not agree with the tax positions taken by USBO. If challenged by the IRS, USBO’s tax positions might not be sustained by the courts. No ruling has been requested from the IRS with respect to any matter affecting USBO or prospective investors.

EACH PROSPECTIVE INVESTOR IS ADVISED TO CONSULT ITS OWN TAX ADVISOR AS TO HOW THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF AN INVESTMENT IN USBO APPLY TO YOU AND AS TO HOW THE APPLICABLE STATE, LOCAL OR FOREIGN TAXES APPLY TO YOU.

75

Tax Status of USBO

USBO is organized and operates as a limited partnership in accordance with the provisions of the LP Agreement and applicable state law. Under the Code, an entity classified as a partnership that is deemed to be a “publicly traded partnership” is generally taxable as a corporation for U.S. federal income tax purposes. The Code provides an exception to this general rule for a publicly traded partnership whose gross income for each taxable year of its existence consists of at least 90% “qualifying income” (“qualifying income exception”). For this purpose, section 7704 defines “qualifying income” as including, in pertinent part, interest (other than from a financial business), dividends and gains from the sale or disposition of capital assets held for the production of interest or dividends. In addition, in the case of a partnership a principal activity of which is the buying and selling of commodities (other than as inventory) or of futures, forwards and options with respect to commodities, “qualifying income” includes income and gains from such commodities and futures, forwards and options with respect to commodities. USBO and the General Partner have represented the following to Reed Smith LLP:

• At least 90% of USBO’s gross income for each taxable year will constitute “qualifying income” within the meaning of Code section 7704 (as described above);

• USBO will be organized and operated in accordance with its governing agreements and applicable law;

• USBO has not elected, and will not elect, to be classified as a corporation for U.S. federal income tax purposes.

Based in part on these representations, Reed Smith LLP is of the opinion that USBO classifies as a partnership for U.S. federal income tax purposes and that it is not taxable as a corporation for such purposes.

If USBO failed to satisfy the qualifying income exception in any year, other than a failure that is determined by the IRS to be inadvertent and that is cured within a reasonable time after discovery, USBO would be taxable as a corporation for U.S. federal income tax purposes and would pay U.S. federal income tax on its income at regular corporate rates. In that event, unitholders would not report their share of USBO’s income or loss on their returns. In addition, distributions to unitholders would be treated as dividend income to the extent of USBO’s current and accumulated earnings and profits. To the extent a distribution exceeded USBO’s earnings and profits, the distribution would be treated as a return of capital to the extent of a unitholder’s basis in its units, and thereafter as gain from the sale of units. Accordingly, if USBO were to be taxable as a corporation, it would likely have a material adverse effect on the economic return from an investment in USBO and on the value of the units.

The remainder of this summary assumes that USBO is classified as a partnership for U.S. federal income tax purposes and that it is not taxable as a corporation.

U.S. Unitholders

Tax Consequences of Ownership of Units

Taxation of USBO’s Income. No U.S. federal income tax is paid by USBO on its income. Instead, USBO files annual information returns, and each U.S. unitholder is required to report on its U.S. federal income tax return its allocable share of the income, gain, loss and deduction of USBO. For example, unitholders must take into account their share of ordinary income realized by USBO from accruals of interest on Treasuries and other investments, and their share of gain from Futures Contracts and Other Crude Oil-Related Investments. These items must be reported without regard to the amount (if any) of cash or property the unitholder receives as a distribution from USBO during the taxable year. Consequently, a unitholder may be allocated income or gain by USBO but receive no cash distribution with which to pay its tax liability resulting from the allocation, or may receive a distribution that is insufficient to pay such liability. Because the General Partner currently does not intend to make distributions, it is likely that in any year USBO realizes net income and/or gain that a U.S. unitholder will be required to pay taxes on its allocable share of such income or gain from sources other than USBO distributions. In addition, for taxable years beginning after December 31, 2012, individuals with income in excess of $200,000 ($250,000 in the case of married individuals filing jointly) and certain estates and trusts are subject to an additional 3.8% tax on their “net investment income,” which generally includes net income from interest, dividends, annuities, royalties, and rents, and net capital gains (other than certain amounts earned from trades or businesses).

Allocations of USBO’s Profit and Loss. Under Code section 704, the determination of a partner’s distributive share of any item of income, gain, loss, deduction or credit is governed by the applicable organizational document unless the allocation provided by such document lacks “substantial economic effect.” An allocation that lacks substantial economic effect nonetheless will be respected if it is in accordance with the partners’ interests in the partnership, determined by taking into account all facts and circumstances relating to the economic arrangements among the partners.

76

In general, USBO applies a monthly closing-of-the-books convention in determining allocations of economic profit or loss to unitholders. Income, gain, loss and deduction are determined on a monthly “mark-to-market” basis, taking into account our accrued income and deductions and realized and unrealized gains and losses for the month. These items are allocated among the holders of units in proportion to the number of units owned by them as of the close of business on the last business day of the month. Items of taxable income, deduction, gain, loss and credit recognized by USBO for U.S. federal income tax purposes for any taxable year will be allocated among holders in a manner that equitably reflects the allocation of economic profit or loss. USBO has made the election permitted by section 754 of the Code, which election is irrevocable without the consent of the Service. The effect of this election is that when a secondary market sale of our units occur, we adjust the purchaser’s proportionate share of the tax basis of our assets to fair market value, as reflected in the price paid for the units, as if the purchaser had directly acquired an interest in our assets. The section 754 election is intended to eliminate disparities between a partner’s basis in its partnership interest and its share of the tax bases of the partnership’s assets, so that the partner’s allocable share of taxable gain or loss on a disposition of an asset will correspond to its share of the appreciation or depreciation in the value of the asset since it acquired its interest. Depending on the price paid for units and the tax bases of USBO’s assets at the time of the purchase, the effect of the section 754 election on a purchaser of units may be favorable or unfavorable.

USBO applies certain assumptions and conventions in determining and allocating items for tax purposes in order to reduce the complexity and costs of administration. The General Partner believes that application of these assumptions and conventions is consistent with the intent of the partnership provisions of the Code, and that the resulting allocations have substantial economic effect or otherwise are respected as being in accordance with unitholders’ interests in USBO for U.S. federal income tax purposes.

However, the Code and Treasury Regulations do not expressly permit adoption of these assumptions and conventions, and Reed Smith LLP is therefore unable to opine on the validity of our allocation method. It is possible that the IRS could successfully challenge this method and require a unitholder to report a greater or lesser share of items of income, gain, loss, deduction, or credit than if our method were respected. The General Partner is authorized to revise our allocation method to conform to any method permitted under future Treasury Regulations.

The assumptions and conventions used in making tax allocations may cause a unitholder to be allocated more or less income or loss for U.S. federal income tax purposes than its proportionate share of the economic income or loss realized by USBO during the period it held its units. This “mismatch” between taxable and economic income or loss in some cases may be temporary, reversing itself in a later year when the units are sold, but could be permanent. For example, a unitholder could be allocated income accruing before it purchased its units, resulting in an increase in the basis of the units (see “Tax Basis of Units”, below). On a subsequent disposition of the units, the additional basis might produce a capital loss the deduction of which may be limited (see “Limitations on Deductibility of Losses and Certain Expenses”, below).

Mark to Market of Certain Exchange-Traded Contracts. For U.S. federal income tax purposes, USBO generally is required to use a “mark-to-market” method of accounting under which unrealized gains and losses on instruments constituting “section 1256 contracts” are recognized currently. A section 1256 contract is defined as: (1) a futures contract that is traded on or subject to the rules of a national securities exchange which is registered with the SEC, a domestic board of trade designated as a contract market by the CFTC, or any other board of trade or exchange designated by the Secretary of the Treasury, and with respect to which the amount required to be deposited and the amount that may be withdrawn depends on a system of “marking to market”; (2) a forward contract on exchange-traded foreign currencies, where the contracts are traded in the interbank market; (3) a non-equity option traded on or subject to the rules of a qualified board or exchange; (4) a dealer equity option; or (5) a dealer securities futures contract.

Under these rules, section 1256 contracts held by USBO at the end of each taxable year, including for example Futures Contracts and options on Futures Contracts traded on a U.S. exchange or board of trade or certain foreign exchanges, are treated as if they were sold by USBO for their fair market value on the last business day of the taxable year. A unitholder’s distributive share of USBO’s net gain or loss with respect to each section 1256 contract generally is treated as long-term capital gain or loss to the extent of 60 percent thereof, and as short-term capital gain or loss to the extent of 40 percent thereof, without regard to the actual holding period.

Many of USBO’s Futures Contracts and some their other commodity interests will qualify as “section 1256 contracts” under the Code. Gain or loss recognized through disposition, termination or marking-to-market of USBO’s section 1256 contracts will be subject to 60-40 treatment and allocated to unitholders in accordance with the monthly allocation convention. Under recently enacted legislation, cleared swaps and other commodity swaps will most likely not qualify as section 1256 contracts. If a commodity swap is not treated as a section 1256 contract, any gain or loss on the swap recognized at the time of disposition or termination will be long-term or short-term capital gain or loss depending on the holding period of the swap.

Limitations on Deductibility of Losses and Certain Expenses. A number of different provisions of the Code may defer or disallow the deduction of losses or expenses allocated to you by USBO, including but not limited to those described below.

A unitholder’s deduction of its allocable share of any loss of USBO will be limited to the lesser of (1) the tax basis in its units or (2) in the case of a unitholder that is an individual or a closely held corporation, the amount which the unitholder is considered to have “at risk” with respect to our activities. In general, the amount at risk will be your invested capital plus your share of any recourse debt of USBO for which you are liable. Losses in excess of the amount at risk must be deferred until years in which USBO generates additional taxable income against which to offset such carryover losses or until additional capital is placed at risk.

77

Noncorporate taxpayers are permitted to deduct capital losses only to the extent of their capital gains for the taxable year plus $3,000 of other income. Unused capital losses can be carried forward and used to offset capital gains in future years. In addition, a noncorporate taxpayer may elect to carry back net losses on section 1256 contracts to each of the three preceding years and use them to offset section 1256 contract gains in those years, subject to certain limitations. Corporate taxpayers generally may deduct capital losses only to the extent of capital gains, subject to special carryback and carryforward rules.

Otherwise deductible expenses incurred by noncorporate taxpayers constituting “miscellaneous itemized deductions,” generally including investment-related expenses (other than interest and certain other specified expenses), are deductible only to the extent they exceed 2 percent of the taxpayer’s adjusted gross income for the year. Although the matter is not free from doubt, we believe management fees we pay to the General Partner and other expenses we incur constitute investment-related expenses subject to the miscellaneous itemized deduction limitation, rather than expenses incurred in connection with a trade or business.

Noncorporate unitholders generally may deduct “investment interest expense” only to the extent of their “net investment income.” Investment interest expense of a unitholder will generally include any interest accrued by USBO and any interest paid or accrued on direct borrowings by a unitholder to purchase or carry its units, such as interest with respect to a margin account. Net investment income generally includes gross income from property held for investment (including “portfolio income” under the passive loss rules but not, absent an election, long-term capital gains or certain qualifying dividend income) less deductible expenses other than interest directly connected with the production of investment income.

To the extent that we allocate losses or expenses to you that must be deferred or disallowed as a result of these or other limitations in the Code, you may be taxed on income in excess of your economic income or distributions (if any) on your units. As one example, you could be allocated and required to pay tax on your share of interest income accrued by USBO for a particular taxable year, and in the same year be allocated a share of a capital loss that you cannot deduct currently because you have insufficient capital gains against which to offset the loss. As another example, you could be allocated and required to pay tax on your share of interest income and capital gain for a year, but be unable to deduct some or all of your share of management fees and/or margin account interest incurred by you with respect to your units. Unitholders are urged to consult their own professional tax advisors regarding the effect of limitations under the Code on your ability to deduct your allocable share of USBO’s losses and expenses.

Tax Basis of Units

A unitholder’s tax basis in its units is important in determining (1) the amount of taxable gain or loss it will realize on the sale or other disposition of its units, (2) the amount of non-taxable distributions that it may receive from USBO and (3) its ability to utilize its distributive share of any losses of USBO on its tax return. A unitholder’s initial tax basis in its units will equal its cost for the units plus its share of USBO’s liabilities (if any) at the time of purchase. In general, a unitholder’s “share” of those liabilities will equal the sum of (i) the entire amount of any otherwise nonrecourse liability of USBO as to which the unitholder or an affiliate of the unitholder is the creditor (a “partner nonrecourse liability”) and (ii) a pro rata share of any nonrecourse liabilities of USBO that are not partner nonrecourse liabilities as to any unitholder.

A unitholder’s tax basis in its units generally will be (1) increased by (a) its allocable share of USBO’s taxable income and gain and (b) any additional contributions by the unitholder to USBO and (2) decreased (but not below zero) by (a) its allocable share of USBO’s tax deductions and losses and (b) any distributions by USBO to the unitholder. For this purpose, an increase in a unitholder’s share of USBO’s liabilities will be treated as a contribution of cash by the unitholder to USBO and a decrease in that share will be treated as a distribution of cash by USBO to the unitholder. Pursuant to certain IRS rulings, a unitholder will be required to maintain a single, “unified” basis in all units that it owns. As a result, when a unitholder that acquired its units at different prices sells less than all of its units, such unitholder will not be entitled to specify particular units ( e.g., those with a higher basis) as having been sold. Rather, it must determine its gain or loss on the sale by using an “equitable apportionment” method to allocate a portion of its unified basis in its units to the units sold.

Treatment of USBO Distributions. If USBO makes non-liquidating distributions to unitholders, such distributions generally will not be taxable to the unitholders for U.S. federal income tax purposes except to the extent that the sum of (i) the amount of cash and (ii) the fair market value of marketable securities distributed exceeds the unitholder’s adjusted basis of its interest in USBO immediately before the distribution. Any cash distributions in excess of a unitholder’s tax basis generally will be treated as gain from the sale or exchange of units.

Constructive Termination of the Partnership. We will be considered to have been terminated for tax purposes if there is a sale or exchange of 50 percent or more of the total interests in our units within a 12-month period. A termination would result in the closing of our taxable year for all unitholders. In the case of a unitholder reporting on a taxable year other than a fiscal year ending December 31, the closing of our taxable year may result in more than 12 months of our taxable income or loss being includable in its taxable income for the year of termination. We would be required to make new tax elections after a termination. A termination could result in tax penalties if we were unable to determine that the termination had occurred. Moreover, a termination might either accelerate the application of, or subject us to, any tax legislation enacted before the termination.

Tax Consequences of Disposition of Units

If a unitholder sells its units, it will recognize gain or loss equal to the difference between the amount realized and its adjusted tax basis for the units sold. A unitholder’s amount realized will be the sum of the cash or the fair market value of other property received plus its share of any USBO debt outstanding.

Gain or loss recognized by a unitholder on the sale or exchange of units held for more than one year will generally be taxable as long-term capital gain or loss; otherwise, such gain or loss will generally be taxable as short-term capital gain or loss. A special election is available under the Treasury Regulations that will allow unitholders to identify and use the actual holding periods for the units sold for purposes of determining whether the gain or loss recognized on a sale of units will give rise to long-term or short-term capital gain or loss. It is expected that most unitholders will be eligible to elect, and generally will elect, to identify and use the actual holding period for units sold. If a unitholder fails to make the election or is not able to identify the holding periods of the units sold, the unitholder will have a split holding period in the units sold. Under such circumstances, a unitholder will be required to determine its holding period in the units sold by first determining the portion of its entire interest in USBO that would give rise to long-term capital gain or loss if its entire interest were sold and the portion that would give rise to short-term capital gain or loss if the entire interest were sold. The unitholder would then treat each unit sold as giving rise to long-term capital gain or loss and short-term capital gain or loss in the same proportions as if it had sold its entire interest in USBO.

Under Section 751 of the Code, a portion of a unitholder’s gain or loss from the sale of units (regardless of the holding period for such units), will be separately computed and taxed as ordinary income or loss to the extent attributable to “unrealized receivables” or “inventory” owned by USBO. The term “unrealized receivables” includes, among other things, market discount bonds and short-term debt instruments to the extent such items would give rise to ordinary income if sold by USBO.

If some or all of your units are lent by your broker or other agent to a third party — for example, for use by the third party in covering a short sale — you may be considered as having made a taxable disposition of the loaned units, in which case —

• you may recognize taxable gain or loss to the same extent as if you had sold the units for cash;

• any of USBO’s income, gain, loss or deduction allocable to those units during the period of the loan will not be reportable by you for tax purposes; and

• any distributions you receive with respect to the units will be fully taxable, most likely as ordinary income.

Unitholders desiring to avoid these and other possible consequences of a deemed disposition of their units should consider modifying any applicable brokerage account agreements to prohibit the lending of their units.

Other Tax Matters

Information Reporting. We report tax information to the unitholders and the IRS. Unitholders who have become additional limited partners are treated as partners for U.S. federal income tax purposes. The IRS has ruled that assignees of partnership interests who have not been admitted to a partnership as partners but who have the capacity to exercise substantial dominion and control over the assigned partnership interests will be considered partners for U.S. federal income tax purposes. On the basis of such ruling, except as otherwise provided herein, we treat the following persons as partners for U.S. federal income tax purposes: (1) assignees of units who are pending admission as limited partners, and (2) unitholders whose units are held in street name or by another nominee and who have the right to direct the nominee in the exercise of all substantive rights attendant to the ownership of their units. USBO will furnish unitholders each year with tax information on IRS Schedule K-1 (Form 1065), which will be used by the unitholders in completing their tax returns.

Persons who hold an interest in USBO as a nominee for another person are required to furnish to us the following information: (1) the name, address and taxpayer identification number of the beneficial owner and the nominee; (2) whether the beneficial owner is (a) a person that is not a U.S. person, (b) a foreign government, an international organization or any wholly-owned agency or instrumentality of either of the foregoing, or (c) a tax-exempt entity; (3) the amount and description of units acquired or transferred for the beneficial owner; and (4) certain information including the dates of acquisitions and transfers, means of acquisitions and transfers, and acquisition cost for purchases, as well as the amount of net proceeds from sales. Brokers and financial institutions are required to furnish additional information, including whether they are U.S. persons and certain information on units they acquire, hold or transfer for their own account. A penalty of $100 per failure, up to a maximum of $1,500,000 per calendar year, is imposed by the Internal Revenue Code of 1986, as amended for failure to report such information to us. The nominee is required to supply the beneficial owner of the units with the information furnished to us.

Partnership Audit Procedures. The IRS may audit the U.S. federal income tax returns filed by USBO. Adjustments resulting from any such audit may require each unitholder to adjust a prior year’s tax liability and could result in an audit of the unitholder’s own return. Any audit of a unitholder’s return could result in adjustments of non-partnership items as well as USBO items. Partnerships are generally treated as separate entities for purposes of U.S. federal tax audits, judicial review of administrative adjustments by the IRS, and tax settlement proceedings. The tax treatment of partnership items of income, gain, loss and deduction are determined at the partnership level in a unified partnership proceeding rather than in separate proceedings with the unitholders. The Code provides for one unitholder to be designated as the “tax matters partner” to represent the partnership purposes of these proceedings. The LP Agreement appoints the General Partner as the tax matters partner of USBO.

79

Tax Shelter Disclosure Rules. In certain circumstances the Code and Treasury Regulations require that the IRS be notified of taxable transactions through a disclosure statement attached to a taxpayer’s U.S. federal income tax return. These disclosure rules may apply to transactions irrespective of whether they are structured to achieve particular tax benefits. They could require disclosure by USBO or unitholders if a unitholder incurs a loss in excess a specified threshold from a sale or redemption of its units or possibly in other circumstances. While these rules generally do not require disclosure of a loss recognized on the disposition of an asset in which the taxpayer has a “qualifying basis” (generally a basis equal to the amount of cash paid by the taxpayer for such asset), they apply to a loss recognized with respect to interests in a pass-through entity, such as the units, even if the taxpayer’s basis in such interests is equal to the amount of cash it paid. In addition, under recently enacted legislation, significant penalties may be imposed in connection with a failure to comply with these reporting requirements. Investors should consult their own tax advisors concerning the application of these reporting requirements to their specific situation.

Tax-Exempt Organizations. Subject to numerous exceptions, qualified retirement plans and individual retirement accounts, charitable organizations and certain other organizations that otherwise are exempt from U.S. federal income tax (collectively “exempt organizations”) nonetheless are subject to the tax on unrelated business taxable income (“UBTI”). Generally, UBTI means the gross income derived by an exempt organization from a trade or business that it regularly carries on, the conduct of which is not substantially related to the exercise or performance of its exempt purpose or function, less allowable deductions directly connected with that trade or business. If USBO were to regularly carry on (directly or indirectly) a trade or business that is unrelated with respect to an exempt organization unitholder, then in computing its UBTI, the unitholder must include its share of (1) USBO’s gross income from the unrelated trade or business, whether or not distributed, and (2) USBO’s allowable deductions directly connected with that gross income.

UBTI generally does not include dividends, interest, or payments with respect to securities loans or gains from the sale of property (other than property held for sale to customers in the ordinary course of a trade or business). Nonetheless, income on, and gain from the disposition of, “debt-financed property” is UBTI. Debt-financed property generally is income-producing property (including securities), the use of which is not substantially related to the exempt organization’s tax-exempt purposes, and with respect to which there is “acquisition indebtedness” at any time during the taxable year (or, if the property was disposed of during the taxable year, the 12-month period ending with the disposition). Acquisition indebtedness includes debt incurred to acquire property, debt incurred before the acquisition of property if the debt would not have been incurred but for the acquisition, and debt incurred subsequent to the acquisition of property if the debt would not have been incurred but for the acquisition and at the time of acquisition the incurrence of debt was foreseeable. The portion of the income from debt-financed property attributable to acquisition indebtedness is equal to the ratio of the average outstanding principal amount of acquisition indebtedness over the average adjusted basis of the property for the year. USBO currently does not anticipate that it will borrow money to acquire investments; however, USBO cannot be certain that it will not borrow for such purpose in the future. In addition, an exempt organization unitholder that incurs acquisition indebtedness to purchase its units in USBO may have UBTI.

The U.S. federal tax rate applicable to an exempt organization unitholder on its UBTI generally will be either the corporate or trust tax rate, depending upon the unitholder’s form of organization. USBO may report to each such unitholder information as to the portion, if any, of the unitholder’s income and gains from USBO for any year that will be treated as UBTI; the calculation of that amount is complex, and there can be no assurance that USBO’s calculation of UBTI will be accepted by the IRS. An exempt organization unitholder will be required to make payments of estimated U.S. federal income tax with respect to its UBTI.

Regulated Investment Companies. Interests in and income from “qualified publicly traded partnerships” satisfying certain gross income tests are treated as qualifying assets and income, respectively, for purposes of determining eligibility for regulated investment company (“RIC”) status. A RIC may invest up to 25% of its assets in interests in a qualified publicly traded partnership. The determination of whether a publicly traded partnership such as USBO is a qualified publicly traded partnership is made on an annual basis. USBO expects to be a qualified publicly traded partnership in each of its taxable years. However, such qualification is not assured.

Non-U.S. Unitholders

Generally, non-U.S. persons who derive U.S. source income or gain from investing or engaging in a U.S. business are taxable on two categories of income. The first category consists of amounts that are fixed, determinable, annual or periodic income, such as interest, dividends and rent that are not connected with the operation of a U.S. trade or business (“FDAP”). The second category is income that is effectively connected with the conduct of a U.S. trade or business (“ECI”). FDAP income (other than interest that is considered “portfolio interest”) is generally subject to a 30 percent withholding tax, which may be reduced for certain categories of income by a treaty between the U.S. and the recipient’s country of residence. In contrast, ECI is generally subject to U.S. tax on a net basis at graduated rates upon the filing of a U.S. tax return. Where a non-U.S. person has ECI as a result of an investment in a partnership, the ECI is subject to a withholding tax at a rate of 35 percent for both individual and corporate unitholders.

80

Withholding on Allocations and Distributions. The Code provides that a non-U.S. person who is a partner in a partnership that is engaged in a U.S. trade or business during a taxable year will also be considered to be engaged in a U.S. trade or business during that year. Classifying an activity by a partnership as an investment or an operating business is a factual determination. Under certain safe harbors in the Code, an investment fund whose activities consist of trading in stocks, securities, or commodities for its own account generally will not be considered to be engaged in a U.S. trade or business unless it is a dealer is such stocks, securities, or commodities. This safe harbor applies to investments in commodities only if the commodities are of a kind customarily dealt in on an organized commodity exchange and if the transaction is of a kind customarily consummated at such place. Although the matter is not free from doubt, USBO believes that the activities directly conducted by USBO do not result in USBO being engaged in a trade or business within the United States. However, there can be no assurance that the IRS would not successfully assert that USBO’s activities constitute a U.S. trade or business.

In the event that USBO’s activities were considered to constitute a U.S. trade or business, USBO would be required to withhold at the highest rate specified in Code section 1 (currently 35 percent) on allocations of our income to non-U.S. unitholders other than corporations and the highest rate specified in Code section 11(b) on allocations of our income to corporate non-U.S. unitholders, when such income is distributed. A Non-U.S. unitholder with ECI will generally be required to file a U.S. federal income tax return, and the return will provide the non-U.S. unitholder with the mechanism to seek a refund of any withholding in excess of such unitholder’s actual U.S. federal income tax liability.

If USBO is not treated as engaged in a U.S. trade or business, a non-U.S. unitholder may nevertheless be treated as having FDAP income, which would be subject to a 30 percent withholding tax (possibly subject to reduction by treaty), with respect to some or all of its distributions from USBO or its allocable share of USBO income.

Any amount withheld by USBO on behalf of a non-U.S. unitholder will be treated as a distribution to the non-U.S. unitholder to the extent possible. In some cases, USBO may not be able to match the economic cost of satisfying its withholding obligations to a particular non-U.S. unitholder, which may result in such cost being borne by USBO generally and, accordingly, by all unitholders.

To the extent any interest income allocated to a non-U.S. unitholder that otherwise constitutes FDAP is considered “portfolio interest,” neither the allocation of such interest income to the non-U.S. unitholder nor a subsequent distribution of such interest income to the non-U.S. unitholder will be subject to withholding, provided that the non-U.S. unitholder is not otherwise engaged in a trade or business in the U.S. and provides USBO with a timely and properly completed and executed IRS Form W-8BEN or other applicable form. In general, “portfolio interest” is interest paid on debt obligations issued in registered form, unless the “recipient” owns 10 percent or more of the voting power of the issuer.

Most of USBO’s interest income qualifies as “portfolio interest.” In order for USBO to avoid withholding on any interest income allocable to non-U.S. unitholders that would qualify as “portfolio interest,” it will be necessary for all non-U.S. unitholders to provide USBO with a timely and properly completed and executed Form W-8BEN (or other applicable form). If a non-U.S. unitholder fails to provide a properly completed Form W-8BEN, the General Partner may request that the non-U.S. unitholder provide, within 15 days after the request by the General Partner, a properly completed Form W-8BEN. If a non-U.S. unitholder fails to comply with this request, the units owned by such non-U.S. unitholder will be subject to redemption.

Gain from Sale of Units. Gain from the sale or exchange of the units may be taxable to a non-U.S. unitholder if the non-U.S. unitholder is a nonresident alien individual who is present in the U.S. for 183 days or more during the taxable year. In such case, the nonresident alien individual will be subject to a 30 percent withholding tax on the amount of such individual’s gain.

Branch Profits Tax on Corporate Non-U.S. Unitholders. In addition to the taxes noted above, any non-U.S. unitholders that are corporations may also be subject to an additional tax, the branch profits tax, at a rate of 30 percent. The branch profits tax is imposed on a non-U.S. corporation’s dividend equivalent amount, which generally consists of the corporation’s after-tax earnings and profits that are effectively connected with the corporation’s U.S. trade or business but are not reinvested in a U.S. business. This tax may be reduced or eliminated by an income tax treaty between the United States and the country in which the non-U.S. unitholder is a “qualified resident.”

Certain information reporting and withholding requirement. Recently enacted legislation that becomes effective after December 31, 2012 generally imposes a 30% withholding tax on payments of certain types of income to foreign financial institutions that fail to enter into an agreement with the United States Treasury to report certain required information with respect to accounts held by U.S. persons (or held by foreign entities that have U.S. persons as substantial owners). The IRS and the Treasury Department have announced that the full implementation of these rules will be phased in over the next several years, including the obligation to withhold. The types of income subject to the tax include U.S. source interest and dividends and the gross proceeds from the sale of any property that could produce U.S.-source interest or dividends. The information required to be reported includes the identity and taxpayer identification number of each account holder that is a U.S. person and transaction activity within the holder’s account. In addition, subject to certain exceptions, this legislation also imposes a 30% withholding tax on payments to foreign entities that are not financial institutions unless the foreign entity certifies that it does not have a greater than 10% U.S. owner or provides the withholding agent with identifying information on each greater 10% U.S. owner. When these provisions become effective, depending on the status of a Non-U.S. Shareholder and the status of the intermediaries through which it holds Shares, a Non-U.S. Shareholder could be subject to this 30% withholding tax with respect to distributions on its Shares and proceeds from the sale of its Shares. Under certain circumstances, a Non-U.S. Shareholder might be eligible for refund or credit of such taxes.

81

Prospective non-U.S. unitholders should consult their tax advisor with regard to these and other issues unique to non-U.S. unitholders.

Backup Withholding

USBO may be required to withhold U.S. federal income tax (“backup withholding”) from all taxable distributions payable to (1) any unitholder who fails to furnish to USBO with his, her or its correct taxpayer identification number or a certificate that the unitholder is exempt from backup withholding, and (2) any unitholder with respect to whom the IRS notifies USBO that the unitholder is subject to backup withholding. Backup withholding is not an additional tax and may be returned or credited against a taxpayer’s regular U.S. federal income tax liability if appropriate information is provided to the IRS.

Other Tax Considerations

In addition to U.S. federal income taxes, unitholders may be subject to other taxes, such as state and local income taxes, unincorporated business taxes, business franchise taxes, and estate, inheritance or intangible taxes that may be imposed by the various jurisdictions in which USBO does business or owns property or where the unitholders reside. Although an analysis of those various taxes is not presented here, each prospective unitholder should consider their potential impact on its investment in USBO. It is each unitholder’s responsibility to file the appropriate U.S. federal, state, local, and foreign tax returns. Reed Smith LLP has not provided an opinion concerning any aspects of state, local or foreign tax or U.S. federal tax other than those U.S. federal income tax issues discussed herein.

Investment by ERISA Accounts

General

Most employee benefit plans and individual retirement accounts (“IRAs”) are subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) or the Internal Revenue Code of 1986, as amended (the “Code”), or both. This section discusses certain considerations that arise under ERISA and the Code that a fiduciary of an employee benefit plan as defined in ERISA or a plan as defined in Section 4975 of the Code who has investment discretion should take into account before deciding to invest the plan’s assets in USBO. Employee benefit plans and plans are collectively referred to below as plans, and fiduciaries with investment discretion are referred to below as plan fiduciaries.

This summary is based on the provisions of ERISA and the Code as of the date hereof. This summary is not intended to be complete, but only to address certain questions under ERISA and the Code likely to be raised by your advisors. The summary does not include state or local law.

Potential plan investors are urged to consult with their own professional advisors concerning the appropriateness of an investment in USBO and the manner in which units should be purchased.

Special Investment Considerations

Each plan fiduciary must consider the facts and circumstances that are relevant to an investment in USBO, including the role that an investment in USBO would play in the plan’s overall investment portfolio. Each plan fiduciary, before deciding to invest in USBO, must be satisfied that the investment is prudent for the plan, that the investments of the plan are diversified so as to minimize the risk of large losses and that an investment in USBO complies with the terms of the plan.

USBO and Plan Assets

A regulation issued under ERISA contains rules for determining when an investment by a plan in an equity interest of a limited partnership will result in the underlying assets of the partnership being deemed plan assets for purposes of ERISA and Section 4975 of the Code. Those rules provide that assets of a limited partnership will not be plan assets of a plan that purchases an equity interest in the partnership if the equity interest purchased is a publicly-offered security. If the underlying assets of a partnership are considered to be assets of any plan for purposes of ERISA or Section 4975 of the Code, the operations of that partnership would be subject to and, in some cases, limited by, the provisions of ERISA and Section 4975 of the Code.

82

The publicly-offered security exception described above applies if the equity interest is a security that is:

(1) freely transferable (determined based on the relevant facts and circumstances);

(2) part of a class of securities that is widely held (meaning that the class of securities is owned by 100 or more investors independent of the issuer and of each other); and

(3) either (a) part of a class of securities registered under Section 12(b) or 12(g) of the Exchange Act or (b) sold to the plan as part of a public offering pursuant to an effective registration statement under the Securities Act of 1933 and the class of which such security is a part is registered under the Exchange Act within 120 days (or such later time as may be allowed by the SEC) after the end of the fiscal year of the issuer in which the offering of such security occurred.

The plan asset regulations under ERISA state that the determination of whether a security is freely transferable is to be made based on all the relevant facts and circumstances. In the case of a security that is part of an offering in which the minimum investment is $10,000 or less, the following requirements, alone or in combination, ordinarily will not affect a finding that the security is freely transferable: (1) a requirement that no transfer or assignment of the security or rights relating to the security be made that would violate any federal or state law, (2) a requirement that no transfer or assignment be made without advance written notice given to the entity that issued the security, and (3) any restriction on the substitution of assignee as a limited partner of a partnership, including a general partner consent requirement, provided that the economic benefits of ownership of the assignor may be transferred or assigned without regard to such restriction or consent (other than compliance with any of the foregoing restrictions).

The General Partner believes that the conditions described above are satisfied with respect to the units. The General Partner believes that the units therefore constitute publicly-offered securities, and the underlying assets of USBO are not considered to constitute plan assets of any plan that purchases units.

Prohibited Transactions

ERISA and the Code generally prohibit certain transactions involving the plan and persons who have certain specified relationships to the plan.

In general, units may not be purchased with the assets of a plan if the General Partner, the clearing brokers, the trading advisors (if any), or any of their affiliates, agents or employees either:

• exercise any discretionary authority or discretionary control with respect to management of the plan;

• exercise any authority or control with respect to management or disposition of the assets of the plan;

• render investment advice for a fee or other compensation, direct or indirect, with respect to any moneys or other property of the plan;

• have any authority or responsibility to render investment advice with respect to any monies or other property of the plan; or

• have any discretionary authority or discretionary responsibility in the administration of the plan.

Also, a prohibited transaction may occur under ERISA or the Code when circumstances indicate that (1) the investment in a unit is made or retained for the purpose of avoiding application of the fiduciary standards of ERISA, (2) the investment in a unit constitutes an arrangement under which USBO is expected to engage in transactions that would otherwise be prohibited if entered into directly by the plan purchasing the unit, (3) the investing plan, by itself, has the authority or influence to cause USBO to engage in such transactions, or (4) a person who is prohibited from transacting with the investing plan may, but only with the aid of certain of its affiliates and the investing plan, cause USBO to engage in such transactions with such person.

Special IRA Rules

IRAs are not subject to ERISA’s fiduciary standards, but are subject to their own rules, including the prohibited transaction rules of Section 4975 of the Code, which generally mirror ERISA’s prohibited transaction rules. For example, IRAs are subject to special custody rules and must maintain a qualifying IRA custodial arrangement separate and distinct from USBO and its custodial arrangement. Otherwise, if a separate qualifying custodial arrangement is not maintained, an investment in the units will be treated as a distribution from the IRA. Second, IRAs are prohibited from investing in certain commingled investments, and the General Partner makes no representation regarding whether an investment in units is an inappropriate commingled investment for an IRA. Third, in applying the prohibited transaction provisions of Section 4975 of the Code, in addition to the rules summarized above, the individual for whose benefit the IRA is maintained is also treated as the creator of the IRA. For example, if the owner or beneficiary of an IRA enters into any transaction, arrangement, or agreement involving the assets of his or her IRA to benefit the IRA owner or beneficiary (or his or her relatives or business affiliates) personally, or with the understanding that such benefit will occur, directly or indirectly, such transaction could give rise to a prohibited transaction that is not exempted by any available exemption. Moreover, in the case of an IRA, the consequences of a non-exempt prohibited transaction are that the IRA’s assets will be treated as if they were distributed, causing immediate taxation of the assets (including any early distribution penalty tax applicable under Section 72 of the Code), in addition to any other fines or penalties that may apply.

83

Exempt Plans

Certain employee benefit plans may be governmental plans or church plans. Governmental plans and church plans are generally not subject to ERISA, nor do the above-described prohibited transaction provisions described above apply to them. These plans are, however, subject to prohibitions against certain related-party transactions under Section 503 of the Code, which operate similar to the prohibited transaction rules described above. In addition, the fiduciary of any governmental or church plan must consider any applicable state or local laws and any restrictions and duties of common law imposed upon the plan.

No view is expressed as to whether an investment in USBO (and any continued investment in USBO), or the operation and administration of USBO, is appropriate or permissible for any governmental plan or church plan under Code Section 503, or under any state, county, local or other law relating to that type of plan.

Allowing an investment in USBO is not to be construed as a representation by USBO, its General Partner, any trading advisor, any clearing broker, the Marketing Agent or legal counsel or other advisors to such parties or any other party that this investment meets some or all of the relevant legal requirements with respect to investments by any particular plan or that this investment is appropriate for any such particular plan. The person with investment discretion should consult with the plan’s attorney and financial advisors as to the propriety of an investment in USBO in light of the circumstances of the particular plan, current tax law and ERISA.

STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus includes “forward-looking statements” which generally relate to future events or future performance. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential” or the negative of these terms or other comparable terminology. All statements (other than statements of historical fact) included in this prospectus that address activities, events or developments that will or may occur in the future, including such matters as changes in inflation in the United States, movements in the stock market, movements in U.S. and foreign currencies, and movements in the commodities markets and indexes that track such movements, USBO’s operations, the General Partner’s plans and references to USBO’s future success and other similar matters, are forward-looking statements. These statements are only predictions. Actual events or results may differ materially.

3.1.3  In connection with the formation of the Partnership under the Act, the General Partner acquired a 2% interest in the profits and losses of the Partnership and made an initial capital contribution to the Partnership in the amount of $20.00, and the Organizational Limited Partner acquired a 98% interest in the profits and losses of the Partnership and made an initial capital contribution to the Partnership in the amount of $980.00. As of the date of the initial offering of Units to the public, the interest of the Organizational Limited Partner shall be redeemed, the initial capital contribution of the Organizational Limited Partner shall be refunded, and the Organizational Limited Partner shall thereupon withdraw and cease to be a Limited Partner. Ninety-eight percent of any interest or other profit that may have resulted from the investment or other use of such initial capital contribution was allocated and distributed to the Organizational Limited Partner, and the balance thereof was allocated and distributed to the General Partner. The General Partner may but shall not be required to make Capital Contributions to the Partnership on or after the date hereof.

3.1.6  Unless approved by a majority of the Limited Partners, the General Partner shall not take any action or refuse to take any reasonable action the effect of which, if taken or not taken, as the case may be, would be to cause the Partnership, to the extent it would materially and adversely affect the Limited Partners, to be taxable as a corporation for federal income tax purposes.

3.1.7  Notwithstanding any other provision of this Agreement, the General Partner is not authorized to institute or initiate on behalf of, or otherwise cause the Partnership to:

ARTICLE 4
  
CAPITAL ACCOUNTS OF PARTNERS AND OPERATION THEREOF

4.1  Capital Accounts.  There shall be established on the books and records of the Partnership for each Partner (or Beneficial Owner in the case of Units held by a nominee) a capital account (a “Capital Account”). It is intended that each Partner’s Capital Account shall be maintained at all times in a manner consistent with Section 704 of the Code and applicable Treasury regulations thereunder, and that the provisions hereof relating to the Capital Accounts shall be interpreted in a manner consistent therewith. For each Accounting Period, the Capital Account of each Partner shall be:

(i) credited with the amount of any Capital Contributions made by such Partner during such Accounting Period;

(ii) credited with any allocation of Profit made to such Partner for such Accounting Period;

(iii) debited with any allocation of Loss made to such Partners for such Accounting Period; and

(iv) debited with the amount of cash paid to such Partner as an amount withdrawn or distributed to such Partner during such Accounting Period, or, in the case of any payment of a withdrawal or distribution in kind, the fair value of the property paid or distributed during such Accounting Period.

4.1.1  For any Accounting Period in which Units are issued or redeemed for cash or other property, the General Partner shall, in accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), adjust the Capital Accounts of all Partners and the carrying value of each Partnership asset upward or downward to reflect any unrealized gain or unrealized loss attributable to each such Partnership asset, as if such unrealized gain or unrealized loss had been recognized on an actual sale of the asset and had been allocated to the Partners at such time pursuant to Article 4.2 of this Agreement in the same manner as any item of gain or loss actually recognized during such period would have been allocated.

4.1.2  To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such item of gain or loss shall be specially allocated to the Partners in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury regulations.

B-6

4.2  Allocation of Profit or Loss.  Profit or Loss for an Accounting Period shall be allocated among the Partners in proportion to the number of Units each Partner holds as of the Close of Business on the last Business Day of such Accounting Period. The General Partner may revise, alter or otherwise modify this method of allocation to the extent it deems necessary to comply with the requirements of Section 704 or Section 706 of the Code and Treasury regulations or administrative rulings thereunder.

4.3  Allocations for Tax Purposes

4.3.1  Except as otherwise provided in this Agreement, for each fiscal year of the Partnership, items of income, deduction, gain, loss, and credit recognized by the Partnership for federal income tax purposes shall be allocated among the Partners in a manner that equitably reflects the amounts credited or debited to each Partner’s Capital Account for each Accounting Period during such fiscal year. Allocations under this Article 4.3 shall be made by the General Partner in accordance with the principles of Sections 704(b) and 704(c) of the Code and in conformity with applicable Treasury regulations promulgated thereunder (including, without limitation, Treasury regulations Sections 1.704-1(b)(2)(iv)(f), 1.704-1(b)(4)(i), and 1.704-3(e)).

4.3.2  Notwithstanding anything else contained in this Article 4, if any Partner has a deficit Capital Account for any Accounting Period as a result of any adjustment of the type described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d)(5) or 1.704-1(b)(2)(ii)(d)(6), then the Partnership’s income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate such deficit as quickly as possible. Any special allocation of items of income or gain pursuant to this Article 4.3.2 shall be taken into account in computing subsequent allocations pursuant to this Article 4 so that the cumulative net amount of all items allocated to each Partner shall, to the extent possible, be equal to the amount that would have been allocated to such Partner if there had never been any allocation pursuant to the first sentence of this Article 4.3.2.

4.3.3  Allocations that would otherwise be made to a Limited Partner under the provisions of this Article 4 shall instead be made to the Beneficial Owner of Units held by a nominee.

4.4  Compliance.  In applying the provisions of this Article 4, the General Partner is authorized to utilize such reasonable accounting conventions, valuation methods and assumptions as the General Partner shall determine to be appropriate and in compliance with the Code and applicable Treasury regulations. The General Partner may amend the provisions of this Agreement to the extent it determines to be necessary to comply with the Code and Treasury regulations.

ARTICLE 5

5.1  Records and Accounting.  The Partnership will keep proper books of record and account of the Partnership at its office located in 1999 Harrison Street, Suite 1530, Oakland, California 94612 or such office, including that of an administrative agent, as it may subsequently designate upon notice to the Limited Partners. These books and records are open to inspection by any person who establishes to the Partnership’s satisfaction that such person is a Limited Partner upon reasonable advance notice at all reasonable times during the usual business hours of the Partnership.

In addition, the account statement will disclose any material business dealings between the Partnership, General Partner, commodity trading advisor (if any), futures commission merchant, or the principals thereof that previously have not been disclosed in the Partnership’s Prospectus or any amendment thereto, other account statements or annual reports.

5.5  Tax Information.  Unless not required to be provided to a Partner, Assignee or Beneficial Owner under the applicable rules and regulations of the Code, the General Partner shall use its best efforts to prepare and to transmit a U.S. federal income tax form K-1 for each Partner, Assignee, or Beneficial Owner or a report setting forth in sufficient detail such transactions effected by the Partnership during each fiscal year as shall enable each Partner, Assignee, or Beneficial Owner to prepare its U.S. federal income tax return, if any, within a reasonable period after the end of such fiscal year.

5.6  Tax Returns.  The General Partner shall cause income tax returns of the Partnership to be prepared and timely filed with the appropriate authorities.

5.7  Tax Matters Partner.  The General Partner is hereby designated as the Partnership’s “Tax Matters Partner,” as defined under Section 6231(a)(7) of the Code. The General Partner is specifically directed and authorized to take whatever steps the General Partner, in its discretion, deems necessary or desirable to perfect such designation, including filing any forms or documents with the U.S. Internal Revenue Service and taking such other action as may from time to time be required under U.S. Treasury regulations. Any Partner shall have the right to participate in any administrative proceedings relating to the determination of Partnership items at the Partnership level. Expenses of such administrative proceedings undertaken by the Tax Matters Partner shall be expenses of the Partnership. Each Partner who elects to participate in such proceedings shall be responsible for any expenses incurred by such Partner in connection with such participation. The cost of any resulting audits or adjustments of a Partner’s tax return shall be borne solely by the affected Partner. In the event of any audit, investigation, settlement or review, for which the General Partner is carrying out the responsibilities of Tax Matters Partner, the General Partner shall keep the Partners reasonably apprised of the status and course of such audit, investigation, settlement or review and shall forward copies of all written communications from or to any regulatory, investigative or judicial authority with regard thereto.

ARTICLE 6
  
FISCAL AFFAIRS

6.1  Fiscal Year.  The fiscal year of the Partnership shall be the calendar year. The General Partner may select an alternate fiscal year.

6.2  Partnership Funds.  Pending application or distribution, the funds of the Partnership shall be deposited in such bank account or accounts, or invested in such interest-bearing or non-interest bearing investment, including, without limitation, checking and savings accounts, certificates of deposit and time or demand deposits in commercial banks, U.S. government securities and securities guaranteed by U.S. government agencies as shall be designed by the General Partner. Such funds shall not be commingled with funds of any other Person. Withdrawals therefrom shall be made upon such signatures as the General Partner may designate.

6.5  Partnership Interests.  Title to the Partnership assets shall be deemed to be owned by the Partnership as an entity, and no Partner or Assignee, individually or collectively, shall have any ownership interest in such Partnership assets or any portion thereof. Title to any or all of the Partnership assets may be held in the name of the Partnership, the General Partner or one or more nominees, as the General Partner may determine. The General Partner hereby declares and warrants that any Partnership assets for which record title is held in the name of the General Partner shall be held by the General Partner for the exclusive use and benefit of the Partnership in accordance with the provisions of this Agreement; provided, however, that the General Partner shall use its reasonable efforts to cause record title to such assets (other than those assets in respect of which the General Partner determines that the expense and difficulty of conveyancing makes transfer of record title to the Partnership impracticable) to be vested in the Partnership as soon as reasonably practicable; provided, that prior to the withdrawal or removal of the General Partner or as soon thereafter as practicable, the General Partner will use reasonable efforts to effect the transfer of record title to the Partnership and, prior to any such transfer, will provide for the use of such assets in a manner satisfactory to the Partnership. All Partnership assets shall be recorded as the property of the Partnership in its books and records, irrespective of the name in which record title to such Partnership assets are held.

(d) the use of the assets of the Partnership (including, without limitation, cash on hand) for any purpose consistent with the terms of this Agreement including, without limitation, the financing of the conduct of the operations of the Partnership, the lending of funds to other Persons, and the repayment of obligations of the Partnership;

(e) the negotiation, execution and performance of any contracts, conveyances or other instruments (including, without limitation, instruments that limit the liability of the Partnership under contractual arrangements to all or particular assets of the Partnership with the other party to the contract to have no recourse against the General Partner or its assets other than its interest in the Partnership, even if same results in the terms of the transaction being less favorable to the Partnership than would otherwise be the case);

7.2  Best Efforts.  The General Partner will use its best efforts to cause the Partnership to be formed, reformed, qualified or registered under assumed or fictitious name statutes or similar laws in any state in which the Partnership owns property or transacts business if such formation, reformation, qualification or registration is necessary in order to protect the limited liability of the Limited Partners or to permit the Partnership lawfully to own property or transact business.

Limited Partners should be aware that performance by the General Partner of its fiduciary duty is measured by the terms of this Agreement as well as applicable law. Limited Partners may also have the right, subject to applicable procedural and jurisdictional requirements, to bring class actions in federal court to enforce their rights under the federal securities laws and the rules and regulations promulgated thereunder by the SEC. Limited Partners who have suffered losses in connection with the purchase or sale of the Units may be able to recover such losses from the General Partner where the losses result from a violation by the General Partner of the federal securities laws. State securities laws may also provide certain remedies to limited partners. Limited Partners are afforded certain rights to institute reparations proceedings under the Commodity Exchange Act for violations of the Commodity Exchange Act or of any rule, regulation or order of the Commodity Futures Trading Commission (“CFTC”) by the General Partner.

7.6  Indemnification 

7.6.1  Notwithstanding any other provision of this Agreement, neither a General Partner nor any employee or other agent of the Partnership nor any officer, director, stockholder, partner, employee or agent of a General Partner (a “Protected Person”) shall be liable to any Partner or the Partnership for any mistake of judgment or for any action or inaction taken, nor for any losses due to any mistake of judgment or to any action or inaction or to the negligence, dishonesty or bad faith of any officer, director, stockholder, partner, employee or agent of the Partnership or any officer, director, stockholder, partner, employee or agent of such General Partner, provided that such officer, director, stockholder, partner, employee or agent of the Partner or officer, director, stockholder, partner, employee or agent of such General Partner was selected, engaged or retained by such General Partner with reasonable care, except with respect to any matter as to which such General Partner shall have been finally adjudicated in any action, suit or other proceeding not to have acted in good faith in the reasonable belief that such Protected Person’s action was in the best interests of the Partnership and except that no Protected Person shall be relieved of any liability to which such Protected Person would otherwise be subject by reason of willful misfeasance, gross negligence or reckless disregard of the duties involved in the conduct of the Protected Person’s office. A General Partner and its officers, directors, employees or partners may consult with counsel and accountants (except for the Partnership’s independent auditors) in respect of Partnership affairs and be fully protected and justified in any action or inaction which is taken in accordance with the advice or opinion of such counsel or accountants (except for the Partnership’s independent auditors), provided that they shall have been selected with reasonable care.

Notwithstanding any of the foregoing to the contrary, the provisions of this Article 7.6.1 and of Article 7.6.2 hereof shall not be construed so as to relieve (or attempt to relieve) a General Partner (or any officer, director, stockholder, partner, employee or agent of such General Partner) of any liability to the extent (but only to the extent) that such liability may not be waived, modified or limited under applicable law, but shall be construed so as to effectuate the provisions of this Article 7.6.1 and of Article 7.6.2 hereof to the fullest extent permitted by law.

7.6.2  The Partnership shall, to the fullest extent permitted by law, but only out of Partnership assets, indemnify and hold harmless a General Partner and each officer, director, stockholder, partner, employee or agent thereof (including persons who serve at the Partnership’s request as directors, officers or trustees of another organization in which the Partnership has an interest as a Unitholder, creditor or otherwise) and their respective legal representatives and successors (hereinafter referred to as a “Covered Person”) against all liabilities and expenses, including but not limited to amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and counsel fees reasonably incurred by any Covered Person in connection with the defense or disposition of any action, suit or other proceedings, whether civil or criminal, before any court or administrative or legislative body, in which such Covered Person may be or may have been involved as a party or otherwise or with which such Covered Person may be or may have been threatened, while in office or thereafter, by reason of an alleged act or omission as a General Partner or director or officer thereof, or by reason of its being or having been such a General Partner, director or officer, except with respect to any matter as to which such Covered Person shall have been finally adjudicated in any such action, suit or other proceeding not to have acted in good faith in the reasonable belief that such Covered Person’s action was in the best interest of the Partnership, and except that no Covered Person shall be indemnified against any liability to the Partnership or Limited Partners to which such Covered Person would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person’s office. Expenses, including counsel fees so incurred by any such Covered Person, may be paid from time to time by the Partnership in advance of the final disposition of any such action, suit or proceeding on the condition that the amounts so paid shall be repaid to the Partnership if it is ultimately determined that the indemnification of such expenses is not authorized hereunder.

As to any matter disposed of by a compromise payment by any such Covered Person, pursuant to a consent decree or otherwise, no such indemnification either for said payment or for any other expenses shall be provided unless such compromise shall be approved as in the best interests of the Partnership, after notice that it involved such indemnification by any disinterested person or persons to whom the questions may be referred by the General Partner, provided that there has been obtained an opinion in writing of independent legal counsel to the effect that such Covered Person appears to have acted in good faith in the reasonable belief that his or her action was in the best interests of the Partnership and that such indemnification would not protect such persons against any liability to the Partnership or its Limited Partners to which such person would otherwise by subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of office. Approval by any disinterested person or persons shall not prevent the recovery from persons of indemnification if such Covered Person is subsequently adjudicated by a court of competent jurisdiction not to have acted in good faith in the reasonable belief that such Covered Person’s action was in the best interests of the Partnership or to have been liable to the Partnership or its Limited Partners by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person’s office.

B-10

The right of indemnification hereby provided shall not be exclusive of or affect any other rights to which any such Covered Person may be entitled. As used in this Article 7.6.2, an “interested Covered Person” is one against whom the action, suit or other proceeding on the same or similar grounds is then or has been pending and a “disinterested person” is a person against whom no actions, suits or other proceedings or another action, suit or other proceeding on the same or similar grounds is then or has been pending. Nothing contained in this Article 7.6.2 shall affect any rights to indemnification to which personnel of a General Partner, other than directors and officers, and other persons may be entitled by contract or otherwise under law, nor the power of the Partnership to purchase and maintain liability insurance on behalf of any such person.

Nothing in this Article 7.6.2 shall be construed to subject any Covered Person to any liability to which he or she is not already liable under this Agreement or applicable law.

7.6.3  Each Limited Partner agrees that it will not hold any Affiliate or any officer, director, stockholder, partner, employee or agent of any Affiliate of the General Partner liable for any actions of such General Partner or any obligations arising under or in connection with this Agreement or the transactions contemplated hereby.

7.7  Resolutions of Conflicts of Interest; Standard of Care.

7.7.1  Unless otherwise expressly provided in this Agreement or any other agreement contemplated hereby, whenever a conflict of interest exists or arises between the General Partner on the one hand, and the Partnership or any Limited Partner, on the other hand, any resolution or course of action by the General Partner in respect of such conflict of interest shall be permitted and deemed approved by all Partners and shall not constitute a breach of this Agreement or of any agreement contemplated hereby or of a duty stated or implied by law or equity, if the resolution or course of action is, or by operation of this Agreement is deemed to be, fair and reasonable to the Partnership. If a dispute arises, it will be resolved through negotiations with the General Partner or by a court located in the State of Delaware. Any resolution of a dispute is deemed to be fair and reasonable to the Partnership if the resolution is:

· approved by the Audit Committee, although no party is obligated to seek such approval and the General Partner may adopt a resolution or course of action that has not received such approval;

· on terms no less favorable to the Limited Partners than those generally being provided to or available from unrelated third parties; and

· fair to the Limited Partners, taking into account the totality of the relationships of the parties involved including other transactions that may be particularly favorable or advantageous to the Limited Partners.

7.7.2  Whenever this Agreement or any other agreement contemplated hereby provides that the General Partner is permitted or required to make a decision (i) in its discretion or under a grant of similar authority or latitude, the General Partner shall be entitled to the extent permitted by applicable law, to consider only such interest and factors as it desires and shall have no duty or obligation to give any consideration to any interest of or factors affecting the partnership or the Limited Partners, or (ii) in its good faith or under another express standard, the General Partner shall act under such express standard and except as required by applicable law, shall not be subject to any other different standards imposed by this Agreement, any other agreement contemplated hereby or applicable law.

7.8  Other Matters Concerning the General Partner.

7.8.1  The General Partner (including the Audit Committee) may rely on and shall be protected in acting or refraining from acting upon any certificate, document or other instrument believed by it to be genuine and to have been signed or presented by the proper party or parties.

7.8.2  The General Partner (including the Audit Committee) may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisors selected by it and any opinion or advice of any such person as to matters which the General Partner (including the Audit Committee) believes to be within such person’s professional or expert competence shall be the basis for full and complete authorization of indemnification and provide legal protection with respect to any action taken or suffered or omitted by the General Partner (including the Audit Committee) hereunder in good faith and in accordance with such opinion or advice.

7.8.3  The General Partner (including the Audit Committee) may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and the General Partner (including the Audit Committee) shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the General Partner in good faith.

7.9  Other Business Ventures.  Any Partner, director, employee, Affiliate or other person holding a legal or beneficial interest in any entity which is a Partner, may engage in or possess an interest in other business ventures of every nature and description, independently or with others, whether such ventures are competitive with the Partnership or otherwise; and, neither the Partnership nor the Partners shall have any right by virtue of this Agreement in or to such independent ventures or to the income or profits derived there from.

B-11

7.10  Contracts with the General Partner or its Affiliates.  The General Partner may, on behalf of the Partnership, enter into contracts with any Affiliate. The validity of any transaction, agreement or payment involving the Partnership and any General Partner or any Affiliate of a General Partner otherwise permitted by the terms of this Agreement shall not be affected by reason of (i) the relationship between the Partnership and the Affiliate of the General Partner, or (ii) the approval of said transaction agreement or payment by officers or directors of the General Partner.

7.11  Additional General Partners.  Additional general partners may be admitted with the consent of the General Partner.

ARTICLE 8
  
RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

8.1  No Participation in Management.  No Limited Partner (other than a General Partner if it has acquired an interest of a Limited Partner) shall take part in the management of the Partnership’s business, transact any business in the Partnership’s name or have the power to sign documents for or otherwise bind the Partnership.

8.2  Limitation of Liability.  Except as provided in the Act, the debts, obligations, and liabilities of the Partnership, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Partnership. A Limited Partner will not be liable for assessments in addition to its initial capital investment in any capital securities representing limited partnership interests. However, a Limited Partner may be required to repay to the Partnership any amounts wrongfully returned or distributed to it under some circumstances.

8.3  Indemnification and Terms of Admission.  Each Limited Partner shall indemnify and hold harmless the Partnership, the General Partner and every Limited Partner who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceedings, whether civil, criminal, administrative or investigative, by reason of or arising from any actual or alleged misrepresentation or misstatement of facts or omission to state facts made (or omitted to be made) by such Limited Partner in connection with any assignment, transfer, encumbrance or other disposition of all or any part of an interest, or the admission of a Limited Partner to the Partnership, against expenses for which the Partnership or such other Person has not otherwise been reimbursed (including attorneys’ fees, judgments, fines and amounts paid in settlement) actually and reasonably incurred by him in connection with such action, suit or proceeding.

8.4  Effective Date.  The effective date of admission of a Limited Partner shall be the date designated by the General Partner in writing to such assignee or transferee.

8.5  Death or Incapacity of Limited Partner.  The death or legal incapacity of a Limited Partner shall not cause dissolution of the Partnership.

8.6  Rights of Limited Partner Relating to the Partnership.

(a) In addition to other rights provided by this Agreement or by applicable law, and except as otherwise limited under this Agreement, each Limited Partner shall have the right, for a purpose reasonably related to such Limited Partner’s interest as a Limited Partner in the Partnership, upon reasonable demand and at such Limited Partner’s own expense:

(i) to obtain true and full information regarding the status of the business and financial condition of the Partnership;

(ii) promptly after becoming available, to obtain a copy of the Partnership’s federal, state and local tax returns for each year;

(iii) to have furnished to it, upon notification to the General Partner, a current list of the name and last known business, residence or mailing address of each Partner;

(iv) to have furnished to it, upon notification to the General Partner, a copy of this Agreement and the Certificate of Limited Partnership and all amendments thereto;

(v) to obtain true and full information regarding the amount of cash contributed by and a description and statement of the value of any other Capital Contribution by each Partner and which each Partner has agreed to contribute in the future, and the date on which each became a Partner; and

(vi) to obtain such other information regarding the affairs of the Partnership as is just and reasonable.

(b)  Notwithstanding any other provision of this Agreement, the General Partner may keep confidential from the Limited Partners and Assignees for such period of time as the General Partner deems reasonable, any information that the General Partner reasonably believes to be in the nature of trade secrets or other information, the disclosure of which the General Partner in good faith believes is not in the best interests of the Partnership or could damage the Partnership or that the Partnership is required by law or by agreements with third parties to keep confidential (other than agreements with Affiliates the primary purpose of which is to circumvent the obligations set forth in this Article 8.6).

ARTICLE 9
  
UNIT CERTIFICATES

9.1  Unit Certificates.  Certificates shall be executed on behalf of the Partnership by any officer either of the General Partner or, if any, of the Partnership.

9.2  Registration Form, Registration of Transfer and Exchange.

9.2.1  The General Partner shall cause to be kept on behalf of the Partnership a register (the “Unit Register”) in which, subject to such reasonable regulations as it may prescribe, the General Partner will provide for the registration and the transfer of Units. The Transfer Agent has been appointed registrar and transfer agent for the purpose of registering and transferring Units as herein provided. The Partnership shall not recognize transfers of Certificates representing Units unless same are effected in the manner described in this Article 9.2. Upon surrender for registration of transfer of any Units evidenced by a Certificate, the General Partner on behalf of the Partnership will execute, and the Transfer Agent will countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or more new Certificates evidencing the same aggregate number of Units as was evidenced by the Certificate so surrendered.

9.2.2  Book-Entry-Only System. 

(a) Global Certificate Only.  Unless otherwise authorized by the General Partner, Certificates for Units will not be issued, other than the one or more Global Certificates issued to the Depository. So long as the Depository Agreement is in effect, Creation Baskets will be issued and redeemed and Units will be transferable solely through the book-entry systems of the Depository and the DTC Participants and their Indirect Participants as more fully described below.

(1) Global Certificate.  The Partnership and the General Partner will enter into the Depository Agreement pursuant to which the Depository will act as securities depository for the Units. Units will be represented by the Global Certificate (which may consist of one or more certificates as required by the Depository), which will be registered, as the Depository shall direct, in the name of Cede & Co., as nominee for the Depository and deposited with, or on behalf of, the Depository. No other certificates evidencing Units will be issued. The Global Certificate shall be in the form attached hereto as Exhibit A and shall represent such Units as shall be specified therein, and may provide that it shall represent the aggregate amount of outstanding Units from time to time endorsed thereon and that the aggregate amount of outstanding Units represented thereby may from time to time be increased or decreased to reflect creations or redemptions of Baskets (as defined in Section 16.1). Any endorsement of a Global Certificate to reflect the amount, or any increase or decrease in the amount, of outstanding Units represented thereby shall be made in such manner and upon instructions given by the General Partner on behalf of the Partnership as specified in the Depository Agreement.

(2) Legend.  Any Global Certificate issued to the Depository or its nominee shall bear a legend substantially to the following effect:

“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), TO THE FUND OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUIRED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.”

(3) The Depository.  The Depository has advised the Partnership and the General Partner as follows: the Depository is a limited-purpose trust company organized under the laws of the State of New York, a member of the U.S. Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended. The Depository was created to hold securities of DTC Participants and to facilitate the clearance and settlement of securities transactions among the DTC Participants in such securities through electronic book-entry changes in accounts of the DTC Participants, thereby eliminating the need for physical movement of securities certificates. “DTC Participants” include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations, some of whom (and/or their representatives) own the Depository. Access to the Depository’s system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect Participants”). The Depository may determine to discontinue providing its service with respect to Creation Baskets and Units by giving notice to the General Partner pursuant to and in conformity with the provisions of the Depository Agreement and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the General Partner shall take action either to find a replacement for the Depository to perform its functions at a comparable cost and on terms acceptable to the General Partner or, if such a replacement is unavailable, to terminate the Partnership.

(4) Beneficial Owners.  As provided in the Depository Agreement, upon the settlement date of any creation, transfer or redemption of Units, the Depository will credit or debit, on its book-entry registration and transfer system, the number of Units so created, transferred or redeemed to the accounts of the appropriate DTC Participants. The accounts to be credited and charged shall be designated by the General Partner on behalf of the Partnership and each Participant, in the case of a creation or redemption of Baskets. Ownership of beneficial interest in Units will be limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Beneficial Owners will be shown on, and the transfer of beneficial ownership by Beneficial Owners will be effected only through, in the case of DTC Participants, records maintained by the Depository and, in the case of Indirect Participants and Beneficial Owners holding through a DTC Participant or an Indirect Participant, through those records or the records of the relevant DTC Participants. Beneficial Owners are expected to receive, from or through the broker or bank that maintains the account through which the Beneficial Owner has purchased Units, a written confirmation relating to their purchase of Units.

B-13

(5) Reliance on Procedures.  Except for those who have provided Transfer Applications to the General Partner, so long as Cede & Co., as nominee of the Depository, is the registered owner of Units, references herein to the registered or record owners of Units shall mean Cede & Co. and shall not mean the Beneficial Owners of Units. Beneficial Owners of Units will not be entitled to have Units registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form and will not be considered the record or registered holder of Units under this Agreement. Accordingly, to exercise any rights of a holder of Units under the Agreement, a Beneficial Owner must rely on the procedures of the Depository and, if such Beneficial Owner is not a DTC Participant, on the procedures of each DTC Participant or Indirect Participant through which such Beneficial Owner holds its interests. The Partnership and the General Partner understand that under existing industry practice, if the Partnership requests any action of a Beneficial Owner, or a Beneficial Owner desires to take any action that the Depository, as the record owner of all outstanding Units, is entitled to take, the Depository will notify the DTC Participants regarding such request, such DTC Participants will in turn notify each Indirect Participant holding Units through it, with each successive Indirect Participant continuing to notify each person holding Units through it until the request has reached the Beneficial Owner, and in the case of a request or authorization to act that is being sought or given by a Beneficial Owner, such request or authorization is given by the Beneficial Owner and relayed back to the Partnership through each Indirect Participant and DTC Participant through which the Beneficial Owner’s interest in the Units is held.

(6) Communication between the Partnership and the Beneficial Owners.  As described above, the Partnership will recognize the Depository or its nominee as the owner of all Units for all purposes except as expressly set forth in this Agreement. Conveyance of all notices, statements and other communications to Beneficial Owners will be effected in accordance with this paragraph. Pursuant to the Depository Agreement, the Depository is required to make available to the Partnership, upon request and for a fee to be charged to the Partnership, a listing of the Unit holdings of each DTC Participant. The Partnership shall inquire of each such DTC Participant as to the number of Beneficial Owners holding Units, directly or indirectly, through such DTC Participant. The Partnership shall provide each such DTC Participant with sufficient copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Partnership shall pay to each such DTC Participant an amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

(7) Distributions.  Distributions on Units pursuant to this Agreement shall be made to the Depository or its nominee, Cede & Co., as the registered owner of all Units. The Partnership and the General Partner expect that the Depository or its nominee, upon receipt of any payment of distributions in respect of Units, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in Units as shown on the records of the Depository or its nominee. The Partnership and the General Partner also expect that payments by DTC Participants to Indirect Participants and Beneficial Owners held through such DTC Participants and Indirect Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants and Indirect Participants. Neither the Partnership nor the General Partner will have any responsibility or liability for any aspects of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in Units, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between the Depository and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants or Indirect Participants or between or among the Depository, any Beneficial Owner and any person by or through which such Beneficial Owner is considered to own Units.

(8) Limitation of Liability.  The Global Certificate to be issued hereunder is executed and delivered solely on behalf of the Partnership by the General Partner in its capacity as such and in the exercise of the powers and authority conferred and vested in it by this Agreement. The representations, undertakings and agreements made on the part of the Partnership in the Global Certificate are made and intended not as personal representations, undertakings and agreements by the General Partner, but are made and intended for the purpose of binding only the Partnership. Nothing in the Global Certificate shall be construed as creating any liability on the General Partner, individually or personally, to fulfill any representation, undertaking or agreement other than as provided in this Agreement.

(9) Successor Depository.  If a successor to the Depository shall be employed as Depository hereunder, the Partnership and the General Partner shall establish procedures acceptable to such successor with respect to the matters addressed in this Section 9.2.2.

(10) Transfer of Units.  Beneficial Owners that are not DTC Participants may transfer Units by instructing the DTC Participant or Indirect Participant holding the Units for such Beneficial Owner in accordance with standard securities industry practice. Beneficial Owners that are DTC Participants may transfer Units by instructing the Depository in accordance with the rules of the Depository and standard securities industry practice.

9.2.3  Except as otherwise provided in this Agreement, the Partnership shall not recognize any transfer of Units until the Certificates (if applicable) and a Transfer Application have been provided to the General Partner evidencing such Units are surrendered for registration of transfer. Such Certificates must be accompanied by a Transfer Application duly executed by the transferee (or the transferee’s attorney-in-fact duly authorized in writing). No charge shall be imposed by the Partnership for such transfer, provided, that, as a condition to the issuance of any new Certificate under this Article 9.2, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed with respect thereto.

B-14

9.3  Mutilated, Destroyed, Lost or Stolen Certificates. 

9.3.1  If any mutilated Certificate is surrendered to the Transfer Agent, the General Partner on behalf of the Partnership, shall execute, and upon its request, the Transfer Agent shall countersign and deliver in exchange therefore, a new Certificate evidencing the same number of Units as the Certificate so surrendered.

9.3.2  The General Partner, on behalf of the Partnership, shall execute, and upon its request, the Transfer Agent shall countersign and deliver a new Certificate in place of any Certificate previously issued if the Record Holder of the Certificate:

(a) makes proof by affidavit, in form and substance satisfactory to the General Partner, that a previously issued Certificate has been lost, destroyed or stolen;

(b) requests the issuance of a new Certificate before the Partnership has received notice that the Certificate has been acquired by a purchaser for value in good faith and without notice of an adverse claim;

(c) if requested by the General Partner, delivers to the Partnership a bond or such other form of security or indemnity as may be required by the General Partner, in form and substance satisfactory to the General Partner, with surety or sureties and with fixed or open penalty as the General Partner may direct, in its sole discretion, to indemnify the Partnership, the General Partner and the Transfer Agent against any claim that may be made on account of the alleged loss, destruction or theft of the Certificate; and

(d) satisfies any other reasonable requirements imposed by the General Partner.

If a Limited Partner or Assignee fails to notify the Partnership within a reasonable time after it has notice of the loss, destruction or theft of a Certificate, and a transfer of the Units represented by the Certificate is registered before the Partnership, the General Partner or the Transfer Agent receives such notification, the Limited Partner or Assignee shall be precluded from making any claim against the Partnership, the General Partner or the Transfer Agent for such transfer or for a new Certificate.

9.3.3  As a condition to the issuance of any new Certificate under this Article 9.3, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including, without limitation, the fees and expenses of the Transfer Agent) connected therewith.

9.4  Record Holder.  The Partnership shall be entitled to recognize the Record Holder as the Limited Partner or Assignee with respect to any Units and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such Units on the part of any other Person, whether or not the Partnership shall have actual or other notice thereof, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any national securities exchange on which the Units are listed for trading. Without limiting the foregoing, when a Person (such as a broker, dealer, bank trust company or clearing corporation or an agent of any of the foregoing) is acting as nominee, agent or in some other representative capacity for another Person in acquiring and/or holding Units, as between the Partnership on the one hand and such other Persons on the other hand such representative Person (a) shall be the Limited Partner or Assignee (as the case may be) of record and beneficially, (b) must execute and deliver a Transfer Application and (c) shall be bound by this Agreement and shall have the rights and obligations of a Limited Partner or Assignee (as the case may be) hereunder and as provided for herein.

9.5  Partnership Securities.  The General Partner is hereby authorized to cause the Partnership to issue Partnership Securities, for any Partnership purpose, at any time or from time to time, to the Partners or to other Persons for such consideration and on such terms and conditions as shall be established by the General Partner in its sole discretion, all without the approval of any Limited Partners. The General Partner shall have sole discretion, subject to the requirements of the Act, in determining the consideration and terms and conditions with respect to any future issuance of Partnership Securities.

9.5.1  The General Partner shall do all things necessary to comply with the Act and is authorized and directed to do all things it deems to be necessary or advisable in connection with any future issuance of Partnership Securities, including, without limitation, compliance with any statute, rule, regulation or guideline of any federal, state or other governmental agency or any national securities exchange on which the Units or other Partnership Securities are listed for trading.

B-15

ARTICLE 10
  
TRANSFER OF INTERESTS

10.1  Transfer.

10.1.1  The term “transfer,” when used in this Article 10 with respect to an interest, shall be deemed to refer to an appropriate transaction by which the General Partner assigns its interest as General Partner to another Person or by which the holder of a Unit assigns such Unit to another Person who is or becomes an Assignee and includes a sale, assignment, gift, pledge, encumbrance, hypothecation, mortgage, exchange or any other disposition by law or otherwise.

10.1.2  No interest shall be transferred in whole or in part, except in accordance with the terms and conditions set forth in this Article 10. Any transfer or purported transfer of an interest not made in accordance with this Article 10 shall be null and void.

10.2  Transfer of General Partner’s Interest.

10.2.1  Except as set forth in this Article 10.2.1, the General Partner may transfer all, but not less than all, of its interest as the general partner to a single transferee if, but only if, (i) at least a majority of the Limited Partners approve of such transfer and of the admission of such transferee as general partner, (ii) the transferee agrees to assume the rights and duties of the General Partner and be bound by the provisions of this Agreement and other applicable agreements, and (iii) the Partnership receives an Opinion of Counsel that such transfer would not result in the loss of limited liability of any Limited Partner or of the Partnership or cause the Partnership to be taxable as a corporation or otherwise taxed as an entity for federal income tax purposes. The foregoing notwithstanding, the General Partner is expressly permitted to pledge its interest as General Partner to secure the obligations of the Partnership under a Revolving Credit Facility, as the same may be amended, supplemented, replaced, refinanced or restated from time to time, or any successor or subsequent loan agreement.

10.2.2  Neither Article 10.2.1 nor any other provision of this Agreement shall be construed to prevent (and all Partners do hereby consent to) (i) the transfer by the General Partner of all of its interest as a general partner to an Affiliate or (ii) the transfer by the General Partner of all its interest as a general partner upon its merger or consolidation with or other combination into any other Person or the transfer by it of all or substantially all of its assets to another Person if, in the case of a transfer described in either clause (i) or (ii) of this sentence, the rights and duties of the General Partner with respect to the interest so transferred are assumed by the transferee and the transferee agrees to be bound by the provisions of this Agreement; provided, that in either such case, such transferee furnishes to the Partnership an Opinion of Counsel that such merger, consolidation, combination, transfer or assumption will not result in a loss of limited liability of any Limited Partner or of the Partnership or cause the Partnership to be taxable as a corporation or otherwise taxed as an entity for federal income tax purpose. In the case of a transfer pursuant to this Article 10.2.2, the transferee or successor (as the case may be) shall be admitted to the Partnership as the General Partner immediately prior to the transfer of the interest, and the business of the Partnership shall continue without dissolution.

10.3  Transfer of Units.

10.3.1  Units may be transferred only in the manner described in Article 9.2. The transfer of any Units and the admission of any new Partner shall not constitute an amendment to this Agreement.

10.3.2  Until admitted as a Substituted Limited Partner pursuant to Article 11, the Record Holder of a Unit shall be an Assignee in respect of such Unit. Limited Partners may include custodians, nominees or any other individual or entity in its own or any representative capacity.

10.3.3  Each distribution in respect of Units shall be paid by the Partnership, directly or through the Transfer Agent or through any other Person or agent, only to the Record Holders thereof as of the Record Date set for the distribution. Such payment shall constitute full payment and satisfaction of the Partnership’s liability in respect of such payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise.

10.3.4  A transferee who has completed and delivered a Transfer Application provided by the seller of the Units (or if purchased on an exchange directly from the Partnership), shall be deemed to have (i) requested admission as a Substituted Limited Partner, (ii) agreed to comply with and be bound by and to have executed this Agreement, (iii) represented and warranted that such transferee has the capacity and authority to enter into this Agreement, (iv) made the powers of attorney set forth in this Agreement, and (v) given the consents and made the waivers contained in this Agreement.

10.4  Restrictions on Transfers.  Notwithstanding the other provisions of this Article 10, no transfer of any Unit or interest therein of any Limited Partner or Assignee shall be made if such transfer would (a) violate the then applicable federal or state securities laws or rules and regulations of the SEC, any state securities commission, the CFTC, or any other governmental authorities with jurisdiction over such transfer, (b) cause the Partnership to be taxable as a corporation or (c) affect the Partnership’s existence or qualification as a limited partnership under the Act. The General Partner may request each Record Holder to furnish certain information, including that holder’s nationality, citizenship or other related status. A transferee who is not a U.S. resident may not be eligible to become a Record Holder or a Limited Partner if such ownership would subject the Partnership to the risk of cancellation or forfeiture of any of its assets under any federal, state or local law or regulation. If the Record Holder fails to furnish the information or if the General Partner determines, on the basis of the information furnished by the holder in response to the request, that such holder is not qualified to become a Limited Partner, the General Partner may be substituted as a holder for the Record Holder, who will then be treated as a non-citizen assignee, and the Partnership will have the right to redeem those securities held by the Record Holder.

10.5  Tax Certificates.

10.5.1  All Limited Partners or Assignees (or, if the Limited Partner or Assignee is a nominee holding for the account of a Beneficial Owner, the Beneficial Owner) are required to provide the Partnership with a properly completed Tax Certificate.

B-16

10.5.2  If a Limited Partner or Assignee (or, if the Limited Partner or Assignee is a nominee holding for the account of a Beneficial Owner, the Beneficial Owner) fails to provide the Partnership with a properly completed Tax Certificate, the General Partner may request at any time and from time to time, that such Limited Partner or Assignee (or Beneficial Owner) shall, within 15 days after request (whether oral or written) therefore by the General Partner, furnish to the Partnership, a properly completed Tax Certificate. If a Limited Partner or Assignee fails to furnish to the General Partner within the aforementioned 15-day period such Tax Certificate, the Units owned by such Limited Partner or Assignee (or in the case of a Limited Partner or Assignee that holds Units on behalf of a Beneficial Owner, the Units held on behalf of the Beneficial Owner) shall be subject to redemption in accordance with the provisions of Article 10.6.

10.6  Redemption of Units for Failure to Provide Tax Certificate.

10.6.1  If at any time a Limited Partner or Assignee fails to furnish a properly completed Tax Certificate within the 15-day period specified in Article 10.5.2, the Partnership may redeem the Units of such Limited Partner or Assignee as follows:

(a) The General Partner shall not later than the tenth (10^th) Business Day before the date fixed for redemption, give notice of redemption to the Limited Partner or Assignee, at its last address designated on the records of the Partnership or the Transfer Agent, by registered or certified mail, postage prepaid. The notice shall be deemed to have been given when so mailed (the “Notice Date”). The notice shall specify the Redeemable Units, the date fixed for redemption, the place of payment, and that payment of the redemption price will be made upon surrender of the certification evidencing the Redeemable Units.

(b) The aggregate redemption price for Redeemable Units shall be an amount equal to the market price as of the Close of Business on the Business Day immediately prior to the date fixed for redemption of Units to be so redeemed multiplied by the number of Units included among the Redeemable Units. The redemption price shall be paid in the sole discretion of the General Partner, in cash or by delivery of a promissory note of the Partnership in the principal amount of the redemption price, bearing interest at the Prime Rate (as established by the Federal Reserve Board) and payable in three equal annual installments of principal together with accrued interest commencing one year after the redemption date.

(c) Upon surrender by or on behalf of the Limited Partner or Assignee, at the place specified in the notice of redemption, of the certification evidencing the Redeemable Units, duly endorsed in blank or accompanied by an assignment duly executed in blank, the Limited Partner or Assignee or its duly authorized representative shall be entitled to receive the payment therefore.

(d) In the event the Partnership is required to pay withholding tax or otherwise withhold any amount on behalf of, or with respect to, a Limited Partner or Assignee (or Beneficial Owner) who has failed to provide a properly completed Tax Certificate, such amounts paid or withheld by the Partnership shall be deemed to have been paid to such Limited Partner or Assignee (or Beneficial Owner) as part of the redemption price for the Redeemable Units and the Partnership shall reduce the amount of the payment made to such Limited Partner or Assignee (or Beneficial owner) in redemption of such Redeemable Units by any amounts so withheld.

10.6.2  After the Notice Date, Redeemable Units shall no longer constitute issued and Outstanding Units and no allocations or distributions shall be made with respect to such Redeemable Units. In addition, after the Notice Date, the Redeemable Units shall not be transferable.

10.6.3  The provisions of this Article 10.6 shall also be applicable to Units held by a Limited Partner or Assignee as nominee of a Beneficial Owner.

ARTICLE 11
  
ADMISSION OF PARTNERS

11.1  Admission of Initial Limited Partners and Other Creation Basket Purchases.  Subject to the requirements of this Article 11, upon the issuance by the Partnership of Units to the Initial Limited Partner and any other purchasers of a Creation Basket, the General Partner shall admit the Initial Limited Partner and such other purchasers of the Creation Basket to the Partnership as Limited Partners in respect of the Units purchased.

11.2  Admission of Substituted Limited Partners.  By transfer of a Unit in accordance with Article 10, the transferor shall be deemed to have given the transferee the right to seek admission as a Substituted Limited Partner subject to the conditions of, and in the manner permitted under, this Agreement. A transferor of a Certificate shall, however, only have the authority to convey to a purchaser or other transferee who does not execute and deliver a Transfer Application (i) the right to negotiate such Certificate to a purchaser or other transferee, and (ii) the right to transfer the right to request admission as a Substituted Limited Partner to such purchaser or other transferee in respect of the transferred Units. Each transferee of a Unit (including, without limitation, any nominee holder or an agent acquiring such Unit for the account of another Person) who executes and delivers a Transfer Application shall, by virtue of such execution and delivery, be an Assignee and be deemed to have applied to become a Substituted Limited Partner with respect to the Units so transferred to such Person. Such Assignee shall become a Substituted Limited Partner (i) at such time as the General Partner consents thereto, which consent may be given or withheld in the General Partner’s sole discretion, and (ii) when any such admission is shown on the books and records of the Partnership, following the consent of the General Partner to such admission.If such consent is withheld, such transferee shall be an Assignee. An Assignee shall have an interest in the Partnership equivalent to that of a Limited Partner with respect to allocations and distributions, including, without limitation, liquidating distributions, of the Partnership. With respect to voting rights attributable to Units that are held by Assignees, the General Partner shall be deemed to be the Limited Partner with respect thereto and shall, in exercising the voting rights in respect of such Units on any matter, vote such Units at the written direction of the Assignee who is the Record Holder of such Units. If no such written direction is received, such Units will not be voted. An Assignee shall have none of the other rights of a Limited Partner.

B-17

11.3  Admission of Successor General Partner.  A successor General Partner approved pursuant to this Article 11.3 or the transferee of or successor to all of the General Partner’s interest pursuant to Article 10.2 who is proposed to be admitted as a successor General Partner shall be admitted to the Partnership as the General Partner, effective immediately prior to the withdrawal or removal of the General Partner pursuant to Article 12 or the transfer of the General Partner’s interest pursuant to Article 10.2; provided, however, that no such successor shall be admitted to the Partnership until compliance with the terms of Article 10.2 has occurred. Any such successor shall carry on the business of the Partnership without dissolution. In each case, the admission shall be subject to the successor General Partner executing and delivering to the Partnership an acceptance of all of the terms and conditions of this Agreement and such other documents or instruments as may be required to effect the admission.

11.4  Admission of Additional Limited Partners.

11.4.1  A Person (other than the General Partner, an Initial Limited Partner or a Substituted Limited Partner) who makes a Capital Contribution to the Partnership in accordance with this Agreement shall be admitted to the Partnership as an Additional Limited Partner only upon furnishing to the General Partner (i) evidence of acceptance in form satisfactory to the General Partner of all of the terms and conditions of this Agreement, including, without limitation, the power of attorney granted in this Agreement, and (ii) such other documents or instruments as may be required in the discretion of the General Partner to effect such Person’s admission as an Additional Limited Partner.

11.4.2  Notwithstanding anything to the contrary in this Article 11.4, no Person shall be admitted as an Additional Limited Partner without the consent of the General Partner, which consent may be given or withheld in the General Partner’s sole discretion. The admission of any Person as an Additional Limited Partner shall become effective on the date upon which the name of such Person is recorded on the books and records of the Partnership, following the consent of the General Partner to such admission.

11.5  Amendment of Agreement and Certificate of Limited Partnership.  To effect the admission to the Partnership of any Partner, the General Partner shall take all steps necessary and appropriate under the Act to amend the records of the Partnership and if necessary, to prepare as soon as practical an amendment of this Agreement and if required by law, to prepare and file an amendment to the Certificate of Limited Partnership and may for this purpose, among others, exercise the power of attorney granted pursuant to Article 15.

ARTICLE 12
  
WITHDRAWAL OR REMOVAL OF PARTNERS

12.1  Withdrawal of the General Partner.

12.1.1  The General Partner shall be deemed to have withdrawn from the Partnership upon the occurrence of any one of the following events (each such event herein referred to as an “Event of Withdrawal”):

(a) the General Partner voluntarily withdraws from the Partnership by giving written notice to the other Partners;

(b) the General Partner transfers all of its rights as general partner pursuant to this Agreement;

(c) the General Partner is removed;

(d) the General Partner (1) makes a general assignment for the benefit of creditors; (2) files a voluntary bankruptcy petition; (3) files a petition or answer seeking for itself a reorganization, arrangement, composition, readjustment liquidation, dissolution or similar relief under any law; (4) files an answer or other pleading admitting or failing to contest the material allegations of a petition filed against the General Partner in a proceeding of the type described in clauses (1) – (3) of this sentence; or (5) seeks, consents to or acquiesces in the appointment of a trustee, receiver or liquidator of the General Partner or of all or any substantial part of its properties;

(e) a final and non-appealable judgment is entered by a court with appropriate jurisdiction ruling that the General Partner is bankrupt or insolvent or a final and non-appealable order for relief is entered by a court with appropriate jurisdiction against the General Partner, in each case under any federal or state bankruptcy or insolvency laws as now or hereafter in effect; or

(f) a certificate of dissolution or its equivalent is filed for the General Partner, or 90 days expire after the date of notice to the General Partner of revocation of its charter without a reinstatement of its charter, under the laws of its state of incorporation.

If an Event of Withdrawal specified in this Article 12.1.1(d), (e) or (f) occurs, the withdrawing General Partner shall give written notice to the Limited Partners within 30 days after such occurrence. The Partners hereby agree that only the Events of Withdrawal described in this Article 12.1 shall result in the withdrawal of the General Partner from the Partnership.

B-18

12.1.2  Withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal will not constitute a breach of this Agreement under the following circumstances: (i) the General Partner voluntarily withdraws by giving at least 90 days’ advance notice to the Limited Partners, such withdrawal to take effect on the date specified in such notice; or (ii) at any time that the General Partner ceases to be a General Partner pursuant to Article 12.1.1(b) or is removed pursuant to Article 12.2. If the General Partner gives a notice of withdrawal pursuant to Article 12.1.1(a), holders of at least a majority of such Outstanding Units (excluding for purposes of such determination any Units owned by the General Partner and its Affiliates) may, prior to the effective date of such withdrawal, elect a successor General Partner. If, prior to the effective date of the General Partner’s withdrawal, a successor is not selected by the Unitholders as provided herein, the Partnership shall be dissolved in accordance with Article 13. If a successor General Partner is elected, such successor shall be admitted immediately prior to the effective time of the withdrawal or removal of the Departing Partner and shall continue the business of the Partnership without dissolution.

12.2  Removal of the General Partner.  The General Partner may be removed only if such removal is approved by the Unitholders holding at least 66 2/3% of the Outstanding Units (excluding for this purpose any Units held by the General Partner and its Affiliates). Any such action by such holders for removal of the General Partner must also provide for the election of a successor General Partner by the Unitholders holding a majority of the Outstanding Units (excluding for this purpose any Units held by the General Partner and its Affiliates). Such removal shall be effective immediately following the admission of a successor General Partner.

12.3  Withdrawal of a Limited Partner other than the Organizational Limited Partner.  In addition to withdrawal of a Limited Partner due to its redemption of Units constituting a Redemption Basket under this Agreement, the General Partner may, at any time, in its sole discretion, require any Limited Partner to withdraw entirely from the Partnership or to withdraw a portion of its Partner Capital Account, by giving not less than 15 days’ advance written notice to the Limited Partner thus designated. In addition, the General Partner without notice may require at any time, or retroactively, withdrawal of all or any portion of the Capital Account of any Limited Partner: (i) that made a misrepresentation to the General Partner in connection with its purchase of Units; or (ii) whose ownership of Units would result in the violation of any law or regulations applicable to the Partnership or a Partner. The Limited Partner thus designated shall withdraw from the Partnership or withdraw that portion of its Partner Capital Account specified in such notice, as the case may be, as of the Close of Business on such date as determined by the General Partner. The Limited Partner thus designated shall be deemed to have withdrawn from the Partnership or to have made a partial withdrawal from its Partner Capital Account, as the case may be, without further action on the part of said Limited Partner and the provisions of Article 17.6 shall apply.

ARTICLE 13
  
TERMINATION AND DISTRIBUTION

13.1  Termination.  The Partnership shall continue in effect from the date of its formation in perpetuity, unless sooner terminated upon the occurrence of any one or more of the following events:

(a) The death, adjudication of incompetence, bankruptcy, dissolution, withdrawal, or removal of a General Partner who is the sole remaining General Partner, unless a majority in interest of the Limited Partners within 90 days after such event elects to continue the Partnership and appoints a successor General Partner; or

(b) The affirmative vote of a majority in interest of the Limited Partners; provided, however, that any such termination shall be subject to the conditions set forth in this Agreement.

13.2  Assumption of Agreements.  No vote by the Limited Partners to terminate the Partnership pursuant to Section 13.1(b) shall be effective unless, prior to or concurrently with such vote, there shall have been established procedures for the assumption of the Partnership’s obligations arising under any agreement to which the Partnership is a party and which is still in force immediately prior to such vote regarding termination, and there shall have been an irrevocable appointment of an agent who shall be empowered to give and receive notices, reports and payments under such agreements, and hold and exercise such other powers as are necessary to permit all other parties to such agreements to deal with such agent as if the agent were the sole owner of the Partnership’s interest, which procedures are agreed to in writing by each of the other parties to such agreements.

13.3  Distribution

13.3.1  Upon termination of the Partnership, the affairs of the Partnership shall be wound up and all of its debts and liabilities discharged or otherwise provided for in the order of priority as provided by law. The fair market value of the remaining assets of the Partnership shall then be determined by the General Partner. Thereupon, the assets of the Partnership shall be distributed to the Partners pro rata in accordance with their Units. Each Partner shall receive its share of the assets in cash or in kind, and the proportion of such share that is received in cash may vary from Partner to Partner, all as the General Partner in its sole discretion may decide. If such distributions are insufficient to return to any Partner the full amount of its Capital Contributions, such Partner shall have no recourse against any other Partner.

13.3.2  The winding up of the affairs of the Partnership and the distribution of its assets shall be conducted exclusively by the General Partner or its successor, which is hereby authorized to do all acts authorized by law for these purposes. Without limiting the generality of the foregoing, the General Partner, in carrying out such winding up and distribution, shall have full power and authority to sell all or any of the Partnership’s assets or to distribute the same in kind to the Partners.

ARTICLE 14
  
MEETINGS

The General Partner may also call a meeting not less than 20 and not more than 60 days prior to the meeting. Any such notice shall state briefly the purpose of the meeting, which shall be held at a reasonable time and place.

15.1  Appointment.  Each Limited Partner and each Assignee hereby constitutes and appoints each of the General Partner and, if a liquidator shall have been selected, the liquidator severally (and any successor to either thereof by merger, transfer, assignment, election or otherwise) and each of their respective authorized officers and attorneys-in-fact with full power of substitution, as its true and lawful agent and attorney-in-fact with full power and authority in its name, place and stead to:

(a) execute, swear to, acknowledge, deliver, file and record in the appropriate public offices (i) all certificates, documents and other instruments (including, without limitation, this Agreement and the Certificate of Limited Partnership and all amendments or restatements thereof) that the General Partner or the liquidator deems necessary or appropriate to form, qualify or continue the existence or qualification of the Partnership as a limited partnership (or a partnership in which the limited partners have limited liability) in the State of Delaware and in all other jurisdictions in which the Partnership may conduct business or own property, (ii) all certificates, documents and other instruments that the General Partner or the liquidator deems necessary or appropriate to reflect, in accordance with its terms, any amendment, change, modification or restatement of this Agreement, (iii) all certificates, documents and other instruments (including, without limitation, conveyances and a certificate of cancellation) that the General Partner or the liquidator deems necessary or appropriate to reflect the dissolution and liquidation of the Partnership pursuant to the terms of this Agreement, (iv) all certificates, documents and other instruments relating to the admission, withdrawal, removal or substitution of any Partner or the Capital Contribution of any Partner, (v) all certificates, documents and other instruments relating to the determination of the rights, preferences and privileges of Units issued, and (vi) all certificates documents and other instruments (including, without limitation, agreements and a certificate of merger) relating to a merger or consolidation of the Partnership;

15.2  Survival.  The foregoing power of attorney is hereby declared to be irrevocable and a power coupled with an interest and it shall survive and not be affected by the subsequent death, incompetence, disability, incapacity, dissolution, bankruptcy or termination of any Limited Partner or Assignee and the transfer of all or any portion of such Limited Partner’s or Assignee’s Partnership interest and shall extend to such Limited Partners or Assignee’s heirs, successors, assigns and personal representatives. Each such Limited Partner or Assignee hereby agrees to be bound by any representation made by the General Partner or the liquidator acting in good faith pursuant to such power of attorney; and each such Limited Partner or Assignee hereby waives any and all defenses that may be available to contest, negate or disaffirm the action of the General Partner or the liquidator taken in good faith under such power of attorney. Each Limited Partner or Assignee shall execute and deliver to the General Partner or the liquidator, within 15 days after receipt of the General Partner’s or the liquidator’s request therefor, such further designations, powers of attorney and other instruments as the General Partner or the liquidator deems necessary to effectuate this Agreement and the purposes of the Partnership.

ARTICLE 16
  
CREATION OF UNITS

16.1  General.  The Partnership will create and redeem Units from time to time, but only in one or more Creation Baskets or Redemption Baskets (a block of 50,000 Units shall be referred to as a “Basket”). The creation and redemption of Baskets will only be made in exchange for delivery to the Partnership or the distribution by the Partnership of the amount of United States government securities with maturities of 2 years or less (“Treasuries”) and any cash represented by the Baskets being created or redeemed, the amount of which will be based on the combined NAV of the number of Units included in the Baskets being created or redeemed determined on the day the order to create or redeem Baskets is properly received.

B-20

16.2  Creation Procedures.  On any Business Day, a Participant, may place an order with the Partnership’s marketing agent to create one or more Baskets. Purchase orders must be placed by 12:00 PM New York time or the close of regular trading on the NYSE Arca, whichever is earlier; except in the case of the initial order to purchase one or more Creation Baskets on the first day the Baskets are to be offered and sold, when such orders shall be placed by 9:00 AM New York time on the day agreed to by the General Partner and the Initial Limited Partner. The day on which the marketing agent receives a valid purchase order is the purchase order date. By placing a purchase order, a Participant agrees to (1) deposit Treasuries, cash, or a combination of Treasuries and cash with the Partnership, and (2) if required by the General Partner in its sole discretion, enter into or arrange for a block trade, an exchange for physical or exchange for swap, or any other over-the-counter energy transaction (through itself or a designated acceptable broker) with the Partnership for the purchase of a number and type of futures contracts at the closing settlement price for such contracts on the purchase order date, as specified in the purchase order form attached to the Authorized Purchaser Agreement. Failure to consummate (1) and (2) above shall result in the cancellation of the order. The number and type of contracts specified shall be determined by the General Partner, in its sole discretion, to meet the Partnership’s investment objective and shall be purchased as a result of the Participant’s purchase of Units. Prior to the delivery of Baskets for a purchase order, the Participant must also have wired to the custodian the non-refundable creation transaction fee described in this Article 16.

16.3  Determination of Required Deposits.  The total deposit required to create each Basket (“Creation Basket Deposit”) is an amount of Treasuries and/or cash with a value that is in the same proportion to the total assets of the Partnership (net of estimated accrued but unpaid fees, expenses and other liabilities) on the date the order to purchase is properly received as the number of Units to be created under the purchase order is in proportion to the total number of Units outstanding on the date the order is received. The General Partner determines, in its sole discretion or in consultation with the administrator of the Partnership, the requirements for Treasuries and the amount of cash, including the maximum permitted remaining maturity of a Treasury and cash that may be included in deposits to create Baskets. The Partnership, or its marketing agent on the Partnership’s behalf, will publish such requirements at the beginning of each Business Day. The amount of cash deposit required is the difference between (i) the aggregate market value of the Treasuries included in a Creation Basket Deposit as of 4:00 PM New York time on the date the order to purchase is properly received and (ii) the total required deposit.

16.4  Delivery of Required Deposits.  A Participant who places a purchase order is responsible for transferring to the Partnership’s account with the custodian the required amount of Treasuries and cash by the end of the third Business Day following the purchase order date. Upon receipt of the deposit amount, the administrator will direct DTC to credit the number of Baskets ordered to the Participant’s DTC account on the third Business Day following the purchase order date. The expense and risk of delivery and ownership of Treasuries until such Treasuries have been received by the custodian on behalf of the Partnership shall be borne solely by the Participant.

16.5  Rejection of Purchase Orders.  The General Partner, or its marketing agent on its behalf, shall have the absolute right but no obligation to reject a purchase order or a Creation Basket Deposit if: (1) it determines that the purchase order or the Creation Basket Deposit is not in proper form; (2) the General Partner, in its sole discretion, believes that the purchase order or the Creation Basket Deposit would have adverse tax consequences to the Partnership, Limited Partners or Unitholders; (3) the acceptance or receipt of the Creation Basket Deposit would, in the opinion of counsel to the General Partner, be unlawful; or (4) circumstances outside the control of the General Partner, marketing agent or custodian make it, for all practical purposes, not feasible to process creations of Baskets (including if the General Partner determines that the investment alternatives available to the Partnership at that time will not enable it to meet its investment objective). None of the General Partner, marketing agent or custodian will be liable for the rejection of any purchase order or Creation Basket Deposit.

16.6  Creation Transaction Fee.  To compensate the Partnership for its expenses in connection with the creation of Baskets, a Participant is required to pay a transaction fee to the Partnership of $1,000 per order to create Baskets. An order may include multiple Baskets. The transaction fee may be reduced, increased or otherwise changed by the General Partner. The General Partner shall notify DTC in advance of any change in the transaction fee and will not implement any increase in the fee for the creation of Baskets until 30 days after the date of the notice.

B-21

ARTICLE 17
  
REDEMPTION OF UNITS

17.1  General.  The procedures by which a Participant can redeem one or more Baskets mirror the procedures for the creation of Baskets. On any Business Day, a Participant may place an order with the marketing agent to redeem one or more Baskets. Redemption orders must be placed by 12:00 PM New York time or the close of regular trading on the NYSE Arca, whichever is earlier. A redemption order so received is effective on the date it is received in satisfactory form by the marketing agent. The day on which the marketing agent receives a valid redemption order is the redemption order date. By placing a redemption order, a Participant agrees to (1) deliver the Baskets to be redeemed through DTC’s book-entry system to the Partnership’s account with its custodian not later than 3:00 PM New York time on the third Business Day following the effective date of the redemption order, and (2) if required by the General Partner in its sole discretion, enter into or arrange for a block trade, an exchange for physical or exchange for swap, or any other over-the-counter energy transaction (through itself or a designated acceptable broker) with the Partnership for the sale of a number and type of futures contracts at the closing settlement price for such contracts on the redemption order date, as specified in the redemption order form attached to the Authorized Purchaser Agreement. Failure to consummate (1) and (2) above shall result in the cancellation of the order. The number and type of contracts specified shall be determined by the General Partner, in its sole discretion, to meet the Partnership’s investment objective and shall be sold as a result of the Participant’s sale of Units. Prior to the delivery of the redemption distribution for a redemption order, the Participant must also have wired to the Partnership’s account with the custodian the non-refundable redemption transaction fee described in this Article 17.

17.2  Determination of Redemption Distribution.  The redemption distribution from the Partnership consists of a transfer to the redeeming Participant of an amount of Treasuries and/or cash with a value that is in the same proportion to the total assets of the Partnership (net of estimated accrued but unpaid fees, expenses and other liabilities) on the date the order to redeem is properly received as the number of Units to be redeemed under the redemption order is in proportion to the total number of Units outstanding on the date the order to redeem is received. The General Partner, directly or through its agent, will determine the requirements for Treasuries and/or the amount of cash, including the maximum permitted remaining maturity of a Treasury, and the proportions of Treasuries and cash, that may be included in distributions to redeem Baskets. The marketing agent will publish such requirements as of 4:00 PM New York time on the redemption order date.

17.3  Delivery of Redemption Distribution.  The redemption distribution due from the Partnership is delivered to the Participant by 3:00 PM New York time on the third Business Day following the redemption order date if, by 3:00 PM New York time on such third Business Day, the Partnership’s DTC account has been credited with the Baskets to be redeemed. If the Partnership’s DTC account has not been credited with all of the Baskets to be redeemed by such time, the redemption distribution is delivered to the extent of whole Baskets received. Any remainder of the redemption distribution is delivered on the next Business Day to the extent of remaining whole Baskets received if the Partnership (1) receives the fee applicable to the extension of the redemption distribution date which the General Partner may, from time to time, determine and (2) the remaining Baskets to be redeemed are credited to the Partnership’s DTC account by 3:00 PM New York time on such next Business Day. Any further remaining amount of the redemption order shall be cancelled and the Participant will indemnify the Partnership for any losses, if any, due to such cancellation, including but not limited to the difference in the price of investments sold as a result of the redemption order and investments made to reflect that such order has been cancelled. Pursuant to instruction from the General Partner, the custodian is also authorized to deliver the redemption distribution notwithstanding that the Baskets to be redeemed are not credited to the Partnership’s DTC account by 3:00 PM New York time on the third Business Day following the redemption order date if the Participant has collateralized its obligation to deliver the Baskets through DTC’s book entry system on such terms as the General Partner may from time to time determine.

17.4  Suspension or Rejection of Redemption orders.  The General Partner may, in its discretion, suspend the right of redemption, or postpone the redemption settlement date, (1) for any period during which any of the ICE Futures Exchange, the NYSE Arca or the New York Stock Exchange is closed other than customary weekend or holiday closings, or trading on the NYSE Arca or the ICE Futures Exchange is suspended or restricted, (2) for any period during which an emergency exists as a result of which delivery, disposal or evaluation of Treasuries is not reasonably practicable, or (3) for such other period as the General Partner determines to be necessary for the protection of the Limited Partners or the Unitholders. None of the General Partner, the marketing agent or the custodian will be liable to any person or in any way for any loss or damages that may result from any such suspension or postponement. The General Partner will reject a redemption order if the order is not in proper form or if the fulfillment of the order, in the opinion of its counsel, might be unlawful. The General Partner may also reject a redemption order if the number of units being redeemed would reduce the remaining outstanding units to 100,000 units (i.e., two baskets) or less.

17.5  Redemption Transaction Fee.  To compensate the Partnership for its expenses in connection with the redemption of Baskets, a Participant is required to pay a transaction fee to the Partnership of $1,000 per order to redeem Baskets. An order may include multiple Baskets. The transaction fee may be reduced, increased or otherwise changed by the General Partner. The General Partner shall notify DTC in advance of any change in the transaction fee and will not implement any increase in the fee for the redemption of Baskets until 30 days after the date of the notice.

17.6  Required Redemption.  The General Partner may, at any time, in its sole discretion, require any Limited Partner to withdraw entirely from the Partnership or to withdraw a portion of its Partner Capital Account, by giving not less than 15 days’ advance written notice to the Limited Partner thus designated. In addition, the General Partner without notice may require at any time, or retroactively, withdrawal of all or any portion of the Capital Account of any Limited Partner: (i) that the General Partner determines is a benefit plan investor (within the meaning of the Department of Labor Regulation (s) 2510.3-101(f)(2)) in order for the assets of the Partnership not to be treated as plan assets under ERISA; (ii) that made a misrepresentation to the General Partner in connection with its purchase of Units; or (iii) whose ownership of Units would result in the violation of any law or regulations applicable to the Partnership or a Partner. The Limited Partner thus designated shall withdraw from the Partnership or withdraw that portion of its Partner Capital Account specified in such notice, as the case may be, as of the Close of Business on such date as determined by the General Partner. The Limited Partner thus designated shall be deemed to have withdrawn from the Partnership or to have made a partial withdrawal from its Partner Capital Account, as the case may be, without further action on the part of said Limited Partner.

18.2  Waiver of Partition.  Each Partner hereby irrevocably waives during the term of the Partnership any right that it may have to maintain any action for partition with respect to any Partnership property.

18.3  Governing Law, Successors, Severability.  This Agreement shall be governed by the laws of the State of Delaware, as such laws are applied by Delaware courts to agreements entered into and to be performed in Delaware by and between residents of Delaware and shall, subject to the restrictions on transferability set forth herein, bind and inure to the benefit of the heirs, executors, personal representatives successors and assigns of the parties hereto. If any provision of this Agreement shall be held to be invalid, the remainder of this Agreement shall not be affected thereby.

Nothing herein shall affect the right of any party to serve legal process in any manner permitted by law or affect its right to bring any action in any other court. Each party agrees that, in the event that any dispute arising from or relating to this Agreement becomes subject to any judicial proceeding, such party, to the fullest extent permitted by applicable law, waives any right it may otherwise have to (a) seek punitive or consequential damages, or (b) request a trial by jury.

18.7  No Waiver.  The failure of any Partner to seek redress for violation, or to insist on strict performance, of any covenant or condition of this Agreement shall not prevent a subsequent act which would have constituted a violation from having the effect of an original violation.

18.8  Legends.  If certificates for any interest or interests are issued evidencing a Limited Partner’s interest in the Partnerships, each such certificate shall bear such legends as may be required by applicable federal and state laws, or as may be deemed necessary or appropriate by the General Partner to reflect restrictions upon transfer contemplated herein.

18.10  Relationship between the Agreement and the Act.  Regardless of whether any provisions of this Agreement specifically refer to particular Default Rules (as defined below), (a) if any provision of this Agreement conflicts with a Default Rule, the provision of this Agreement controls and the Default Rule is modified or negated accordingly, and (b) if it is necessary to construe a Default Rule as modified or negated in order to effectuate any provision of this Agreement, the Default Rule is modified or negated accordingly. For purposes of this Article 18.10, “Default Rule” shall mean a rule stated in the Act that applies except to the extent it is negated or modified through the provisions of the Partnership’s certificate of limited partnership or this Agreement.

The Commodity Interest Markets

General

The CEA governs the regulation of commodity interest transactions, markets and intermediaries. The CEA provides for varying degrees of regulation of commodity interest transactions depending upon: (1) the type of instrument being traded (e.g., contracts for future delivery, options, swaps or spot contracts), (2) the type of commodity underlying the instrument (distinctions are made between instruments based on agricultural commodities, energy and metals commodities and financial commodities), (3) the nature of the parties to the transaction (retail, eligible contract participant, or eligible commercial entity), (4) whether the transaction is entered into on a principal-to-principal or intermediated basis, (5) the type of market on which the transaction occurs, and (6) whether the transaction is subject to clearing through a clearing organization.

The offer and sale of units of USBO, as well as units of each of the Related Public Funds, is registered under the 1933 Act. USBO and the Related Public Funds are subject to the requirements of the Securities Act, the Exchange Act and the rules and regulations adopted thereunder as administered by the SEC. Firm’s participation in the distribution of units are regulated as described above, as well as by the self-regulatory association, FINRA.

Futures Contracts

A futures contract is a standardized contract traded on, or subject to the rules of, an exchange that calls for the future delivery of a specified quantity and type of a commodity at a specified time and place. Futures contracts are traded on a wide variety of commodities, including agricultural products, bonds, stock indices, interest rates, currencies, energy and metals. The size and terms of futures contracts on a particular commodity are identical and are not subject to any negotiation, other than with respect to price and the number of contracts traded between the buyer and seller.

The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity or by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery. The difference between the price at which the futures contract is purchased or sold and the price paid for the offsetting sale or purchase, after allowance for brokerage commissions, constitutes the profit or loss to the trader. Some futures contracts, such as stock index contracts, settle in cash (reflecting the difference between the contract purchase/sale price and the contract settlement price) rather than by delivery of the underlying commodity.

In market terminology, a trader who purchases a futures contract is long in the market and a trader who sells a futures contract is short in the market. Before a trader closes out his long or short position by an offsetting sale or purchase, his outstanding contracts are known as open trades or open positions. The aggregate amount of open positions held by traders in a particular contract is referred to as the open interest in such contract.

Forward Contracts

A forward contract is a contractual obligation to purchase or sell a specified quantity of a commodity at or before a specified date in the future at a specified price and, therefore, is economically similar to a futures contract. Unlike futures contracts, however, forward contracts are typically traded in the over-the-counter markets and are not standardized contracts. Forward contracts for a given commodity are generally available for various amounts and maturities and are subject to individual negotiation between the parties involved. Moreover, generally there is no direct means of offsetting or closing out a forward contract by taking an offsetting position as one would a futures contract on a U.S. exchange. If a trader desires to close out a forward contract position, he generally will establish an opposite position in the contract but will settle and recognize the profit or loss on both positions simultaneously on the delivery date. Thus, unlike in the futures contract market where a trader who has offset positions will recognize profit or loss immediately, in the forward market a trader with a position that has been offset at a profit will generally not receive such profit until the delivery date, and likewise a trader with a position that has been offset at a loss will generally not have to pay money until the delivery date. In recent years, however, the terms of forward contracts have become more standardized, and in some instances such contracts now provide a right of offset or cash settlement as an alternative to making or taking delivery of the underlying commodity.

In general, the CFTC does not regulate the interbank and forward foreign currency markets with respect to transactions in contracts between certain sophisticated counterparties such as USBO or between certain regulated institutions and retail investors. Although U.S. banks are regulated in various ways by the Federal Reserve Board, the Comptroller of the Currency and other U.S. federal and state banking officials, banking authorities do not regulate the forward markets to the same extent that the swap markets will be regulated by the CFTC once the Dodd-Frank Act is fully implemented. At a minimum, over-the-counter currency forwards, options and swaps will be subject to heightened recordkeeping, reporting and business conduct standards.

SAI-3

On November 16, 2012, the Secretary of the Treasury issued a final determination that exempts both foreign exchange swaps and foreign exchange forwards from the definition of “swap” and, by extension, additional regulatory requirements (such as clearing and margin). The final determination does not extend to other foreign exchange derivatives, such as foreign exchange options, currency swaps, and non-deliverable forwards.

While the U.S. government does not currently impose any restrictions on the movements of currencies, it could choose to do so. The imposition or relaxation of exchange controls in various jurisdictions could significantly affect the market for that and other jurisdictions’ currencies. Trading in the interbank market also exposes USBO to a risk of default since failure of a bank with which USBO had entered into a forward contract would likely result in a default and thus possibly substantial losses to USBO.

Options on Futures Contracts

Options on futures contracts are standardized contracts traded on an exchange. An option on a futures contract gives the buyer of the option the right, but not the obligation, to take a position at a specified price (the striking, strike, or exercise price) in the underlying futures contract or underlying interest. The buyer of a call option acquires the right, but not the obligation, to purchase or take a long position in the underlying interest, and the buyer of a put option acquires the right, but not the obligation, to sell or take a short position in the underlying interest.

The seller, or writer, of an option is obligated to take a position in the underlying interest at a specified price opposite to the option buyer if the option is exercised. Thus, the seller of a call option must stand ready to take a short position in the underlying interest at the strike price if the buyer should exercise the option. The seller of a put option, on the other hand, must stand ready to take a long position in the underlying interest at the strike price.

A call option is said to be in-the-money if the strike price is below current market levels and out-of-the-money if the strike price is above current market levels. Conversely, a put option is said to be in-the-money if the strike price is above the current market levels and out-of-the-money if the strike price is below current market levels.

Options have limited life spans, usually tied to the delivery or settlement date of the underlying interest. Some options, however, expire significantly in advance of such date. The purchase price of an option is referred to as its premium, which consists of its intrinsic value (which is related to the underlying market value) plus its time value. As an option nears its expiration date, the time value shrinks and the market and intrinsic values move into parity. An option that is out-of-the-money and not offset by the time it expires becomes worthless. On certain exchanges, in-the-money options are automatically exercised on their expiration date, but on others unexercised options simply become worthless after their expiration date.

Regardless of how much the market swings, the most an option buyer can lose is the option premium. The option buyer deposits his premium with his broker, and the money goes to the option seller. Option sellers, on the other hand, face risks similar to participants in the futures markets. For example, since the seller of a call option is assigned a short futures position if the option is exercised, his risk is the same as someone who initially sold a futures contract. Because no one can predict exactly how the market will move, the option seller posts margin to demonstrate his ability to meet any potential contractual obligations.

Options on Forward Contracts or Commodities

Options on forward contracts or commodities operate in a manner similar to options on futures contracts. An option on a forward contract or commodity gives the buyer of the option the right, but not the obligation, to take a position at a specified price in the underlying forward contract or commodity. However, similar to forward contracts, options on forward contracts or on commodities are individually negotiated contracts between counterparties and are typically traded in the over-the-counter market. Therefore, options on forward contracts and physical commodities possess many of the same characteristics of forward contracts with respect to offsetting positions and credit risk that are described above.

Swap Contracts

Swap transactions generally involve contracts between two parties to exchange a stream of payments computed by reference to a notional amount and the price of the asset that is the subject of the swap. Swap contracts are principally traded off-exchange, although certain swap contracts are also traded in electronic trading facilities and cleared through clearing organizations.

Swaps are usually entered into on a net basis, that is, the two payment streams are netted out in a cash settlement on the payment date or dates specified in the agreement, with the parties receiving or paying, as the case may be, only the net amount of the two payments. Swaps do not generally involve the delivery of underlying assets or principal. Accordingly, the risk of loss with respect to swaps is generally limited to the net amount of payments that the party is contractually obligated to make. In some swap transactions one or both parties may require collateral deposits from the counterparty to support that counterparty’s obligation under the swap agreement. If the counterparty to such a swap defaults, the risk of loss consists of the net amount of payments that the party is contractually entitled to receive less any collateral deposits it is holding.

SAI-4

Some swap transactions are cleared through central counterparties. These transactions, known as cleared swaps, involve two counterparties first agreeing to the terms of a swap transaction, then submitting the transaction to a clearing house that acts as the central counterparty. Once accepted by the clearing house, the original swap transaction is novated and the central counterparty becomes the counterparty to a trade with each of the original parties based upon the trade terms determined in the original transaction. In this manner each individual swap counterparty reduces its risk of loss due to counterparty nonperformance because the clearing house acts as the counterparty to each transaction.

Regulation

Futures exchanges in the United States are subject to varying degrees of regulation under the CEA depending on whether such exchange is a designated contract market, exempt board of trade or electronic trading facility. Clearing organizations are also subject to the CEA and the rules and regulations adopted thereunder and administered by the CFTC. The CFTC is the governmental agency charged with responsibility for regulation of futures exchanges and commodity interest trading conducted on those exchanges. The CFTC’s function is to implement the CEA’s objectives of preventing price manipulation and excessive speculation and promoting orderly and efficient commodity interest markets. In addition, the various exchanges and clearing organizations themselves exercise regulatory and supervisory authority over their member firms.

The CFTC also regulates the activities of “commodity trading advisors” and “commodity pool operators” and the CFTC has adopted regulations with respect to certain of such persons’ activities. Pursuant to its authority, the CFTC requires a CPO, such as the General Partner, to keep accurate, current and orderly records with respect to each pool it operates. The CFTC may suspend, modify or terminate the registration of any registrant for failure to comply with CFTC rules or regulations. Suspension, restriction or termination of the General Partner’s registration as a CPO would prevent it, until such time (if any) as such registration were to be reinstated, from managing, and might result in the termination of, USBO or the Related Public Funds.

The CEA also gives the states certain powers to enforce its provisions and the regulations of the CFTC.

Under certain circumstances, the CEA grants unitholders the right to institute a reparations proceeding before the CFTC against the General Partner (as a registered commodity pool operator), as well as those of their respective employees who are required to be registered under the CEA. Unitholders may also be able to maintain a private right of action for certain violations of the CEA.

Pursuant to authority in the CEA, the NFA has been formed and registered with the CFTC as a registered futures association. The NFA is the only self-regulatory association for commodities professionals other than the exchanges. As such, the NFA promulgates rules governing the conduct of commodity professionals and disciplines those professionals that do not comply with such standards. The CFTC has delegated to the NFA responsibility for the registration of commodity pool operation. The General Partner is a member of the NFA. As a member of the NFA, the General Partner is subject to NFA standards relating to fair trade practices, financial condition, and consumer protection. The CFTC is prohibited by statute from regulating trading on foreign commodity exchanges and markets.

The CEA requires all futures commission merchants (“FCMs”), such as USBO’s clearing brokers, to meet and maintain specified fitness and financial requirements, to segregate customer funds from proprietary funds and account separately for all customers’ funds and positions, and to maintain specified books and records open to inspection by the staff of the CFTC. The CFTC has similar authority over introducing brokers, or persons who solicit or accept orders for commodity interest trades but who do not accept margin deposits for the execution of trades. The CEA authorizes the CFTC to regulate trading by futures commission merchants and by their officers and directors, permits the CFTC to require action by exchanges in the event of market emergencies, and establishes an administrative procedure under which customers may institute complaints for damages arising from alleged violations of the CEA. The CEA also gives the states powers to enforce its provisions and the regulations of the CFTC.

The regulations of the CFTC and the NFA prohibit any representation by a person registered with the CFTC or by any member of the NFA, that registration with the CFTC, or membership in the NFA, in any respect indicates that the CFTC or the NFA, as the case may be, has approved or endorsed that person or that person’s trading program or objectives. The registrations and memberships of the parties described in this summary must not be considered as constituting any such approval or endorsement. Likewise, no futures exchange has given or will give any similar approval or endorsement.

The regulation of commodity interest trading in the United States and other countries is an evolving area of the law. The various statements made in this summary are subject to modification by legislative action and changes in the rules and regulations of the CFTC, the NFA, the futures exchanges, clearing organizations and other regulatory bodies.

SAI-5

On July 21, 2010, a broad financial regulatory reform bill, the Dodd-Frank Act, was signed into law. All of the Dodd-Frank Act’s provisions became effective on July 16, 2011, but the actual implementation of some of the provisions is subject to continuing uncertainty because implementing rules and regulations have not been completely finalized and have been challenged in court. Pending final resolution of all applicable regulatory requirements, some specific examples of how the new Dodd-Frank Act provisions and rules adopted thereunder could impact USBO are discussed below.

Futures Contracts and Position Limits

Provisions in the Dodd-Frank Act include the requirement that position limits be established on a wide range of commodity interests including energy-based and other commodity futures contracts, certain cleared commodity swaps and certain over-the-counter commodity contracts; new registration, recordkeeping, capital and margin requirements for “swap dealers” and “major swap participants” as determined by the new law and applicable regulations; and the forced use of clearinghouse mechanisms for most swap transactions that are currently entered into in the over-the-counter market. The new law and the rules thereunder may negatively impact USBO’s ability to meet its investment objective either through limits or requirements imposed on it or upon its counterparties. Further, increased regulation of, and the imposition of additional costs on, swap transactions under the new legislation and implementing regulations could cause a reduction in the swap market and the overall derivatives markets, which could restrict liquidity and adversely affect USBO. In particular, new position limits imposed on USBO or its counterparties may impact USBO’s ability to invest in a manner that most efficiently meets its investment objective, and new requirements, including capital and mandatory clearing, may increase the cost of USBO’s investments and doing business, which could adversely impact the ability of USBO to achieve its investment objective.

In October 2011, the CFTC finalized rules that establish position limits with respect to 28 physical delivery commodity futures and options contracts, as well as to forward contracts that are economically equivalent to such contracts (the “Position Limit Rules”). The Position Limit Rules were scheduled to become effective on October 12, 2012. However, on September 28, 2012, the United States District Court for the District of Columbia vacated these regulations on the basis of ambiguities in the provisions of the Commodity Exchange Act (as modified by the Dodd-Frank Act) upon which the regulations were based. In its September 28th decision, the court remanded the Position Limit Rules to the CFTC with instructions to use its expertise and experience to resolve the ambiguities in the statute. On November 15, 2012, the CFTC indicated that it would move forward with an appeal of the District Court’s decision to vacate the Position Limit Rules. At this time, it is not possible to predict how the CFTC’s appeal could affect USBO, but it may be substantial and adverse. Furthermore, until such time as the appeal is resolved or, if applicable revisions to the Position Limit Rules are proposed and adopted, the regulatory architecture in effect prior to the enactment of the Position Limit Rules will govern transactions in commodities and related derivatives. As a result, USBO may be limited with respect to the size of its investments in any commodities subject to these limits. Finally, subject to certain narrow exceptions, the vacated Position Limit Rules would have required the aggregation, for purposes of the position limits, of all positions in the 28 Referenced Contracts held by a single entity and its affiliates, regardless of whether such position existed on U.S. futures exchanges, non-U.S. futures exchanges, in cleared swaps or in over-the-counter swaps. The CFTC is presently considering new aggregation rules, under a rulemaking proposal that is distinct from the Position Limit Rules. At this time, it is unclear how any modified aggregation rules may affect USBO, but it may be substantial and adverse. By way of example, the aggregation rules in combination with any potential revised Position Limit Rules may negatively impact the ability of USBO to meet its investment objectives through limits that may inhibit the General Partner’s ability to sell additional Creation Baskets of USBO.

Based on its current understanding of the final position limit regulations, the General Partner does not anticipate significant negative impact on the ability of USBO to achieve its investment objective.

“Swap” Transactions

The Dodd-Frank Act imposes new regulatory requirements on certain “swap” transactions that USBO is authorized to engage in that may ultimately impact the ability of USBO to meet its investment objective. On August 13, 2012, the CFTC and the SEC published joint final rules defining the terms “swap” and “security- based swap.” The term “swap” is broadly defined to include various types of over-the-counter derivatives, including swaps and options. The effective date of these final rules was October 12, 2012.

SAI-6

The Dodd-Frank Act requires that certain transactions ultimately falling within the definition of “swap” be executed on organized exchanges or “swap execution facilities” and cleared through regulated clearing organizations (which are referred to in the Dodd-Frank Act as “derivative clearing organizations” (“DCOs”)), if the CFTC mandates the central clearing of a particular contract. However, the CFTC has not issued any mandatory clearing determinations and therefore, it is currently unknown which swaps will be subject to such trading and clearing requirements. If a swap is required to be cleared, the initial margin will be set by the clearing organization, subject to certain regulatory requirements and guidelines. Initial and variation margin requirements for swap dealers and major swap participants who enter into uncleared swaps and capital requirements for swap dealers and major swap participants who enter into both cleared and uncleared trades will be set by the CFTC, the SEC or the applicable “Prudential Regulator.” On May 23, 2012, the CFTC published final regulations, which became effective as of July 23, 2012, to determine which entities will be regulated as “swap dealers” and “major swap participants” and thus have to comply with these capital and margin requirements (as well as a multitude of other requirements under the Dodd-Frank Act). Most of the requirements imposed became effective on October 12, 2012, when additional final rules defining the terms “swap,” “security-based swap,” and “mixed swap” became effective. However, on October 11, 2012 and October 12, 2012, the CFTC issued several no-action letters and interpretive guidance which delayed much of the implementation of the requirements from October 12, 2012 until December 31, 2012. Increased regulation of, and the imposition of additional costs on, swap transactions could have an adverse effect on USBO by, for example, reducing the size of and therefore liquidity in the derivatives market, increasing transaction costs and decreasing the ability to customize derivative transactions.

On February 7, 2012, the CFTC published a rule requiring each FCM and DCO to segregate cleared swaps and related collateral posted by a customer of the FCM from the assets of the FCM or DCO, although such property can be commingled with the property of other cleared swaps customers of the FCM or DCO. This rule addresses losses incurred by a DCO in a so-called “double default” scenario in which a customer of an FCM defaults in its obligations to the FCM and the FCM, in turn, defaults in its obligations to the DCO. Under this scenario, the DCO can only access the collateral attributable to other customers of the DCO whose cleared swap positions are in a loss position following the primary customer’s default. This rule became effective on November 8, 2012. Some market participants have expressed concern that the requirements of this segregation rule may result in higher initial margins or higher fees. USBO does not anticipate any impact to their operations in order to meet the requirements of the new rule.

Additionally, the CFTC published rules on February 17, 2012 and April 3, 2012 that require “swap dealers” and “major swap participants” to: 1) adhere to business conduct standards, 2) implement policies and procedures to ensure compliance with the CEA and 3) maintain records of such compliance. These new requirements may impact the documentation requirements for both cleared and non-cleared swaps and cause swap dealers and major swap participants to face increased compliance costs that, in turn, may be passed along to counterparties (such as USBO) in the form of higher fees and expenses that related to trading swaps.

On February 24, 2012, the CFTC amended certain disclosure obligations to require that the operator of a commodity pool that invests in swaps include standardized swap risk disclosures in the pool’s disclosure documents by December 31, 2012.

On December 5, 2012, the CFTC’s Division of Market Oversight issued a letter providing swap dealers with time-limited no-action relief from swap data reporting obligations with respect to equity swaps, foreign exchange swaps and other commodity swaps. For these asset classes, the letter provides swap dealers with reporting relief (i) with respect to real-time price reporting and regular swap reporting (under Part 43 and Part 45 of the CFTC’s regulations, respectively), until February 28, 2013, and (ii) historical swap reporting requirements (under Part 46 of the CFTC’s regulations) until March 30, 2013.

On December 21, 2012, the CFTC’s Division of Market Oversight issued two letters providing certain swap dealers with time-limited no-action relief from some swap data reporting obligations. One letter provides relief from reporting requirements for branches of swap dealers located in emerging markets who encounter technical difficulties in complying with the reporting rules. The letter also provides that swap dealers may delay reporting compliance for certain complex and exotic swaps until April 30, 2012.

Under a second letter, all swap dealers have until April 10, 2013 to report certain information about their counterparties, including: status as a major swap participant, a financial entity, a U.S. person or a commercial end-user.

On December 18, 2012, the CFTC deferred the compliance date for many of the Dodd-Frank Act’s external business conduct standards from December 31, 2012 to May 1, 2013, and for some requirements to July 1, 2013, providing swap dealers an additional four to six months from the original compliance date.

The effect of the future regulatory change on USBO is impossible to predict, but it could be substantial and adverse.

Commodity Margin

Original or initial margin is the minimum amount of funds that must be deposited by a commodity interest trader with the trader’s broker to initiate and maintain an open position in futures contracts. Maintenance margin is the amount (generally less than the original margin) to which a trader’s account may decline before he must deliver additional margin. A margin deposit is like a cash performance bond. It helps assure the trader’s performance of the futures contracts that he or she purchases or sells. Futures contracts are customarily bought and sold on initial margin that represents a very small percentage (ranging upward from less than 5%) of the aggregate purchase or sales price of the contract. Because of such low margin requirements, price fluctuations occurring in the futures markets may create profits and losses that, in relation to the amount invested, are greater than are customary in other forms of investment or speculation. As discussed below, adverse price changes in the futures contract may result in margin requirements that greatly exceed the initial margin. In addition, the amount of margin required in connection with a particular futures contract is set from time to time by the exchange on which the contract is traded and may be modified from time to time by the exchange during the term of the contract.

Brokerage firms, such as USBO’s clearing brokers, carrying accounts for traders in commodity interest contracts may not accept lower, and generally require higher, amounts of margin as a matter of policy to further protect themselves. The clearing brokers require USBO to make margin deposits equal to exchange minimum levels for all commodity interest contracts. This requirement may be altered from time to time in the clearing brokers’ discretion.

SAI-7

Regulators have not yet finalized the Dodd-Frank rules regarding initial margin levels for over-the-counter derivatives. It is possible that such levels may be higher than those for futures contracts. Also, initial margin requirements for non-cleared swaps will be subject to higher margin requirements than cleared swaps. And, under pending rule proposals, USBO may be required to post, but not be entitled to receive, initial and variation margin in respect of non-cleared swaps. Until such time as the regulators finalize these margin rules, trading in the over-the-counter markets where no clearing facility is provided generally will not require margin per se. Rather, it will involve the extension of credit between counterparties that is secured by transfers of credit support and/or independent amounts. Credit support is transferred between counterparties in respect of the open over-the-counter derivatives entered into between them, while independent amounts are fixed amounts posted by one or both counterparties at the execution of a particular over-the-counter transaction.

When a trader purchases an option, there is no margin requirement; however, the option premium must be paid in full. When a trader sells an option, on the other hand, he or she is required to deposit margin in an amount determined by the margin requirements established for the underlying interest and, in addition, an amount substantially equal to the current premium for the option. The margin requirements imposed on the selling of options, although adjusted to reflect the probability that out-of-the-money options will not be exercised, can in fact be higher than those imposed in dealing in the futures markets directly. Complicated margin requirements apply to spreads and conversions, which are complex trading strategies in which a trader acquires a mixture of options positions and positions in the underlying interest.

Margin requirements are computed each day by a trader’s clearing broker. When the market value of a particular open commodity interest position changes to a point where the margin on deposit does not satisfy maintenance margin requirements, a margin call is made by the broker. If the margin call is not met within a reasonable time, the broker may close out the trader’s position. With respect to USBO’s trading, USBO (and not its investors personally) is subject to margin calls.

Finally, many major U.S. exchanges have passed certain cross margining arrangements involving procedures pursuant to which the futures and options positions held in an account would, in the case of some accounts, be aggregated and margin requirements would be assessed on a portfolio basis, measuring the total risk of the combined positions.

Potential Advantages of Investment

The Advantages of Non-Correlation

Given that historically, the price of crude oil and of Futures Contracts and Other Crude Oil-Related Investments has had very little correlation to the stock and bond markets, the General Partner believes that the performance of USBO should also exhibit a substantial degree of non-correlation with the performance of traditional equity and debt portfolio components, in part because of the ease of selling commodity interests short. This feature of many commodity interest contracts — being able to be long or short a commodity interest position with similar ease — means that profit and loss from commodity interest trading is not dependent upon economic prosperity or stability.

However, non-correlation will not provide any diversification advantages unless the non-correlated assets are outperforming other portfolio assets, and it is entirely possible that USBO may not outperform other sectors of an investor’s portfolio, or may produce losses. Additionally, although adding USBO’s units to an investor’s portfolio may provide diversification, USBO is not a hedging mechanism vis-à-vis traditional debt and equity portfolio components and you should not assume that USBO units will appreciate during periods of inflation or stock and bond market declines.

Non-correlated performance should not be confused with negatively correlated performance. Negative correlation occurs when the performance of two asset classes are in opposite direction to each other. Non-correlation means only that USBO’s performance will likely have little relation to the performance of equity and debt instruments, reflecting the General Partner’s belief that certain factors that affect equity and debt prices may affect USBO differently and that certain factors that affect equity and debt prices may not affect USBO at all. USBO’s net asset value per unit may decline or increase more or less than equity and debt instruments during both rising and falling cash markets. The General Partner does not expect that USBO’s performance will be negatively correlated to general debt and equity markets.

Item  14.     Indemnification of Directors and Officers

Neither the General Partner nor any employee or other agent of United States Brent Oil Fund, LP (“USBO”) nor any officer, director, stockholder, partner, employee or agent of the General Partner (a “Protected Person”) shall be liable to any partner or USBO for any mistake of judgment or for any action or inaction taken, nor for any losses due to any mistake of judgment or to any action or inaction or to the negligence, dishonesty or bad faith of any officer, employee, broker or other agent of USBO or any officer, director, stockholder, partner, employee or agent of such General Partner, provided that such officer, director, stockholder, employee, broker or agent of the partner or officer, employee, partner or agent of such General Partner was selected, engaged or retained by such General Partner with reasonable care, except with respect to any matter as to which such General Partner shall have been finally adjudicated in any action, suit or other proceeding not to have acted in good faith in the reasonable belief that such Protected Person’s actions was in the best interests of USBO and except that no Protected person shall be relieved of any liability to which such Protected Person would otherwise be subject by reason of willful misfeasance, gross negligence or reckless disregard of the duties involved in the conduct of the Protected Person’s office. A General Partner and its officers, directors, employees or partners may consult with counsel and accountants (except for USBO’s independent auditors) in respect of USBO affairs and be fully protected and justified in any action or inaction which is taken in accordance with the advice or opinion of such counsel or accountants (except for the Partnership’s independent auditors), provided that they shall have been selected with reasonable care. Notwithstanding any of the foregoing to the contrary, this provision hereof shall not be construed so as to relieve (or attempt to relieve) a General Partner (or any employee or other agent thereof or any partner, employee or agent of such General Partner) of any liability to the extent (but only to the extent) that such liability may not be waived, modified or limited under applicable law, but shall be construed so as to effectuate these provisions hereof to the fullest extent permitted by law.

USBO shall, to the fullest extent permitted by law, but only out of USBO assets, indemnify and hold harmless the General Partner and each officer, director, employee and agent thereof (including persons who serve at USBO’s request as directors, officers or trustees of another organization in which USBO has an interest as a unitholder, creditor or otherwise) and their respective legal representatives and successors (hereinafter referred to as a “Covered Person” against all liabilities and expenses, including but not limited to amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and counsel fees reasonably incurred by any Covered Person in connection with the defense or disposition of any action, suit or other proceedings, whether civil or criminal, before any court or administrative or legislative body, in which such Covered Person may be or may have been involved as a party or otherwise or with which such person may be or may have been threatened, while in office or thereafter, by reason of an alleged act or omission as a General Partner or officer thereof or by reason of its being or having been such a General Partner or officer, except with respect to any matter as to which such Covered Person shall have been finally adjudicated in any such action, suit or other proceeding not to have acted in good faith in the reasonable believe that such Covered Person’s action was in the best interest of the Fund, and except that no Covered Person shall be indemnified against any liability to USBO or Limited Partners to which such Covered Person would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person’s office. Expenses, including counsel fees so incurred by any such Covered Person, may be paid from time to time by USBO in advance of the final disposition of any such action, suit or proceeding on the condition that the amounts so paid shall be repaid to USBO if it is ultimately determined that the indemnification of such expenses is not authorized hereunder.

As to any matter disposed of by a compromise payment by any such Covered Person, pursuant to a consent decree or otherwise, no such indemnification either for said payment or for any other expenses shall be provided unless such compromise shall be approved as in the best interests of USBO, after notice that it involved such indemnification by any disinterested person or persons to whom the questions may be referred by the General Partner, provided that there has been obtained an opinion in writing of independent legal counsel to the effect that such Covered Person appears to have acted in good faith in the reasonable belief that his or her action was in the best interests of USBO and that such indemnification would not protect such persons against any liability to USBO or its Limited Partners to which such person would otherwise by subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of office. Approval by any disinterested person or persons shall not prevent the recovery from persons as indemnification if such Covered Person is subsequently adjudicated by a court of competent jurisdiction not to have acted in good faith in the reasonable belief that such Covered Person’s action was in the best interests of USBO or to have been liable to USBO or its Limited Partners by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person’s office.

The right of indemnification hereby provided shall not be exclusive of or affect any other rights to which any such Covered Person may be entitled. An “interested Covered Person” is one against whom the action, suit or other proceeding on the same or similar grounds is then or has been pending and a “disinterested person” is a person against whom none of such actions, suits or other proceedings or another action, suit or other proceeding on the same or similar grounds is then or has been pending. Nothing contained herein shall affect any rights to indemnification to which personnel of a General Partner, other than directors and officers, and other persons may be entitled by contract or otherwise under law, nor the power of USBO to purchase and maintain liability insurance on behalf of any such person.

Item 15.     Recent Sales of Unregistered Securities

Item 17.        Undertakings

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) If the registrant is subject to Rule 430C (§230.430C of this chapter), each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A (§230.430A of this chapter), shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424 (§230.424 of this chapter);

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

II-3

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(c) The undersigned registrant hereby undertakes:

(1) To send to each limited partner at least on an annual basis a detailed statement of any transactions with the General Partner or its affiliates, and of fees, commissions, compensation and other benefits paid, or accrued to the General Partner or its affiliates for the fiscal year completed, showing the amount paid or accrued to each recipient and the services performed.

(2) o provide to the limited partners the financial statements required by Form 10-K for the first full fiscal year of operations of the partnership.
