PRELIMINARY PROSPECTUS |  | SUBJECT TO COMPLETION

# United States Brent Oil Fund, LP

# 50,000,000 Units

United States Brent Oil Fund, LP, a Delaware limited partnership, is a commodity pool that will issue units that may be purchased and sold on the NYSE Arca. United States Brent Oil Fund, LP is referred to as USBO throughout this document. The investment objective of USBO is to have the daily changes in percentage terms of the units’ net asset value reflect the daily changes in percentage terms of the spot price of Brent crude oil as measured by the 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. This is a best efforts offering. USBO will continuously offer creation baskets consisting of 100,000 units to authorized purchasers through ALPS Distributors, Inc., which is the marketing agent. [ TBD ] is expected to be the initial authorized purchaser. Authorized purchasers will pay a transaction fee of $1,000 for each order to create one or more baskets. There are no arrangements to place funds in an escrow, trust, or similar account. This will be a continuous offering and will not terminate until the earlier of when all of the registered units have been sold or three years following the effectiveness of this registration statement.

| • | It is anticipated that on the effective date (the date the Securities and Exchange Commission declares the registration statement relating to this prospectus effective), the initial authorized purchaser will, though it is under no obligation to do so, purchase one or more initial creation baskets of 100,000 units at a price per unit of $50.00. It is expected that the proceeds from that purchase will be invested on that day and that USBO’s initial per unit net asset value will be established as of 4:00 p.m. New York City time that day. The units are expected to begin trading on the NYSE Arca under the ticker symbol “BNO” on the day following the effective date. Units offered in creation baskets on any day after the effective date will be offered at the per unit net asset value calculated shortly after the close of the core trading session on the NYSE Arca.

| • | Authorized purchasers will be the only persons that may place orders to create and redeem baskets. 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 net asset value of USBO at the time the authorized purchaser purchased the creation basket and the net asset value 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 crude oil 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 net asset value and the trading price of the units on the NYSE Arca 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. Units initially comprising the same basket but offered by authorized purchasers to the public at different times may have different offering prices. Units are expected to 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 net asset value per unit. The amount of the discount or premium in the trading price relative to the net asset value 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 crude oil futures contract market and the market for other crude oil-related investments. Authorized purchasers will not be required to sell any specific number or dollar amount of units.

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 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.

| • | USBO has no operating history so there is no performance history to serve as a basis for you to evaluate an investment in USBO.

Investing in USBO involves other significant risks. See “What Are the Risk Factors Involved with an Investment in USBO?” beginning on page 12.

# 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 12, 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 will issue units that may be purchased and sold on the NYSE Arca. USBO was organized as a limited partnership under Delaware law on September 2, 2009 and is currently operating pursuant to the Amended and Restated Agreement of Limited Partnership dated [TBD] (the “LP Agreement”) which is included as Appendix B. It is expected that the initial limited partner of USBO will be [TBD]. It is managed and controlled by its general partner, United States Commodity Funds 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”). Prior to June 13, 2008, the General Partner’s name was Victoria Bay Asset Management, LLC. USBO will pay the General Partner a management fee of 0.75% of NAV on its average net assets.

The net assets of USBO will 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 (formerly, the International Petroleum Exchange), New York Mercantile Exchange (the “NYMEX”), or other U.S. and foreign exchanges (collectively, “Futures Contracts”). USBO may also invest in 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”). 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 General Partner is authorized by USBO in its sole judgment to employ, establish the terms of employment for, and terminate commodity trading advisors or futures commission merchants.

USBO will invest 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 positions in Futures Contracts and Other Crude Oil-Related Investments. The primary focus of the General Partner will be investing in Futures Contracts and the management of 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 to have the daily changes in percentage terms of its units’ net asset value (“NAV”) reflect the daily changes in percentage terms of the spot price of Brent crude oil as measured by the 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. 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 will endeavor 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

1

TABLE OF CONTENTS

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

An investment in the units is intended to allow both retail and institutional investors to easily gain exposure to the crude oil market in a cost-effective manner. The units are also expected to provide additional means for diversifying an investor’s investments or hedging exposure to changes in crude oil prices.

The Benchmark Futures Contract will be changed from the near month contract to the next month contract over a four-day period. Each month, the Benchmark Futures Contract will change starting at the end of the day on the date two weeks prior to expiration of the near month contract for that month. During the first three days of the period, the applicable value of the Benchmark Futures Contract will be based on a combination of the near month contract and the next month contract as follows: (1) day 1 will consist of 75% of the then near month contract’s total return for the day, plus 25% of the total return for the day of the next month contract, (2) day 2 will consist of 50% of the then near month contract’s total return for the day, plus 50% of the total return for the day of the next month contract, and (3) day 3 will consist of 25% of the then near month contract’s total return for the day, plus 75% of the total return for the day of the next month contract. On day 4, the Benchmark Futures Contract will be the next month contract to expire at that time and that contract will remain the Benchmark Futures Contract until the beginning of 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 oil investments by closing, or selling, a percentage of USBO’s positions in oil interests and reinvesting the proceeds from closing those positions in new oil interests that reflect the change in the Benchmark Futures Contract.

The anticipated dates that the monthly four-day roll period will commence for 2009 will be posted on USBO’s website at www.unitedstatesbrentoilfund.com, and are subject to change without notice.

The General Partner will employ 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 taking positions indirectly in 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 crude oil-related transactions. Accordingly, depending on the investment objective of an individual investor, the risks generally associated with taking positions in 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. For example, USBO will also invest in Treasuries and hold cash and/or cash equivalents to be used to meet its current or potential margin or collateral requirements with respect to its positions in Futures Contracts and Other Crude Oil-Related Investments. USBO does not expect there to be any meaningful correlation between the performance of USBO’s investments in Treasuries/cash/ cash equivalents and the changes in the price of crude oil. While the level of interest earned on or the market price of these investments may in some respect correlate to changes in the price of crude oil, this correlation is not anticipated as part of USBO’s efforts to meet its objectives.

This and certain risk factors discussed in this prospectus may cause a lack of correlation between the changes in USBO’s NAV and the changes in the price of Brent crude oil.

USBO will create and redeem units only in blocks of 100,000 units called Creation Baskets and Redemption Baskets, respectively. Only Authorized Purchasers may purchase or redeem Creation Baskets or Redemption Baskets. 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. It is expected that baskets will be created when there is sufficient demand for units that 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 Baskets 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

2

TABLE OF CONTENTS

fall between USBO’s NAV and the trading price of the units on the NYSE Arca at the time of sale. Similarly, it is expected that baskets will be 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 are expected to 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.

The minimum number of Creation Baskets that must be sold is one. All proceeds from the sale of Creation Baskets will be invested as quickly as possible in the investments described in this prospectus. There will be no escrow or similar holding of funds that has a time period or other conditions. Investments will be held through USBO’s custodian, Brown Brothers Harriman & Co. (“Custodian”), or through accounts with USBO’s commodity futures brokers. There is no stated maximum time period for USBO’s operations and the fund will continue until all units are redeemed or the fund is liquidated pursuant to the terms of the LP Agreement.

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 maximum amount 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.

Units may also be purchased and sold by individuals and entities that are not Authorized Purchasers in smaller increments than Creation Baskets on the NYSE Arca. However, these transactions will be effected at bid and ask prices established by specialist firm(s). Like any listed security, units of USBO can be purchased and sold at any time a secondary market is open.

In managing USBO’s assets, the General Partner does not intend to use a technical trading system that issues buy and sell orders. The General Partner intends instead to employ quantitative methodologies whereby each time one or more baskets are purchased or redeemed, the General Partner will purchase or sell positions in the 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 will consist of 100,000 units and may 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 will also be listed and traded on the NYSE Arca under the ticker symbol “BNO” 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 will not be redeemable securities. There is no guarantee that units will trade at or near the per-unit NAV.

## The Units

The units are registered as securities under the Securities Act of 1933 (“1933 Act”) and the Securities Exchange Act of 1934 (“Exchange Act”) and will not provide dividend rights or conversion rights and there will not be sinking funds. The units may only be redeemed when aggregated in Redemption Baskets as discussed under “Creation and Redemption of Units” and limited partners will have limited voting rights as discussed under “Who is the General Partner?” Cumulative voting will neither be permitted nor required and there will be no preemptive rights. As discussed in the LP Agreement, upon liquidation of USBO, its assets will be distributed pro rata to limited partners based upon the number of units held. Each limited partner will 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, as the General Partner in its sole discretion may decide.

This will be a continuous offering under Rule 415 of the 1933 Act and will terminate when all of the registered units have been sold. It is anticipated that when all registered units have been sold pursuant to this

3

TABLE OF CONTENTS

registration statement, additional units will be registered in subsequent registration statements. As discussed above, the minimum purchase requirement for Authorized Purchasers is a Creation Basket, which will consist of 100,000 units. Under the plan of distribution, USBO does not require a minimum purchase amount for investors who purchase units from Authorized Purchasers. There are no arrangements to place funds in an escrow, trust, or similar account.

## USBO’s Investments in Crude Oil Interests

A brief description of the principal types of Crude Oil Interests in which USBO may invest is set forth below.

| • | A futures contract is a standardized contract traded on a futures exchange that calls for the future delivery of a specified quantity of a commodity at a specified time and place.

| • | A forward contract is a supply contract between principals, not traded on an exchange, to buy or sell a specified quantity of a commodity on or before a specified date at a specified price.

| • | A spot contract is a cash market transaction in which the buyer and seller agree to the immediate purchase and sale of a commodity, usually with a two-day settlement. Spot contracts are not uniform and are not exchange-traded.

| • | An option on a futures contract, forward contract or a commodity on the spot market gives the buyer of the option the right, but not the obligation, to buy or sell a futures contract, forward contract or a commodity as applicable, at a specified price on or before a specified date. Options on futures contracts are standardized contracts traded on an exchange, while options on forward contracts and commodities on the spot market, referred to collectively in this prospectus as over-the-counter options, generally are individually negotiated, principal-to-principal contracts not traded on an exchange.

| • | Over-the-counter contracts (such as swap contracts) generally involve an exchange of a stream of payments between the contracting parties. Over-the-counter contracts generally are not uniform and not exchange-traded.

A more detailed description of Crude Oil Interests and other aspects of the crude oil and crude oil interests markets can be found later in this prospectus.

As noted, USBO expects to invest primarily in Futures Contracts, including those traded on the ICE Futures Exchange. USBO expressly disclaims any association with such exchange or endorsement of USBO by such exchange and acknowledges that “ICE” and “ICE Futures Exchange” are registered trademarks of such exchange.

## 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 12.

| • | 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 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.

| • | There is the risk that the changes in the price of USBO’s units on the NYSE Arca will not closely track the changes in the 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 closely correlate 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 indirectly invest in crude oil or as a hedge against the risk of loss in crude oil-related transactions.

TABLE OF CONTENTS

| • | USBO seeks to have the changes in its units’ NAV in percentage terms track changes in the price of Brent crude oil in percentage terms rather than profit from speculative trading of Crude Oil Interests. The General Partner will therefore endeavor 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, you could lose all or substantially all of your investment if USBO’s trading positions suddenly turn unprofitable. 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.

| • | 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 the event of a crude oil futures market where near month contracts trade at a higher price than next month contracts to expire, 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 Futures Contract would tend to rise as it approaches expiration. As a result positions in 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 to expire, 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, positions in the Benchmark Futures Contract would tend to track lower. When compared to the total return of other price indices, such as the spot price of Brent crude oil, the impact of backwardation and contango may lead the total return of USBO’s NAV to vary significantly. In the event of a prolonged period of contango, and absent the impact of rising or falling crude oil prices, this could have a significant negative impact on USBO’s NAV and total return.

| • | Investors may choose to use USBO as a means of indirectly taking positions 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, for example, due to changes in supply and demand for crude oil as a result of refinery shutdowns or changes in the weather. 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.

| • | Investors, including those who directly participate in the crude oil industry, may choose to use USBO as a vehicle to hedge against the risk of loss associated with the rising cost of crude oil, and there are risks involved in hedging activities. 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.

| • | 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 expects to invest 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.

| • | 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.

| • | USBO will pay fees and expenses that are incurred regardless of whether it is profitable.

| • | 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.

| • | 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 Heating Oil Fund, LP (“USHO”), the United States Short Oil Fund, LP (USSO”) or the United States 12 Month Natural Gas Fund (“US12NG”) or, other commodity pools that it manages, or any other commodity pool the General Partner may form and manage in the future. USOF, USNG, US12OF, UGA, USHO, USSO and US12NG, are referred to herein as the “Related Public Funds.”

| • | Regulation of the commodity interest and energy markets is extensive and constantly changing. Currently, a number of proposals that would alter the regulation of Crude Oil Interests are being considered by federal regulators and Congress. These proposals include the imposition of fixed positions on energy-based commodity futures contracts, extension of position and accountability limits to futures contracts on non-U.S. exchanges previously exempt from such limits, and the forced use of clearinghouse mechanisms for all over-the-counter transactions. Certain proposals would aggregate and limit all positions in energy futures held by a single entity, whether such positions exist on U.S. futures exchanges, non-U.S. futures exchanges, or in over-the-counter contracts. While it cannot be predicted at this time what reforms will eventually be made or how they will impact USBO, if any of the aforementioned proposals are implemented, USBO’s ability to meet its investment objective may be negatively impacted and investors could be adversely affected.

| • | USBO is new and has no operating history. Therefore, you do not have the benefit of reviewing the past performance of USBO as a basis for you to evaluate an investment in USBO.

## Breakeven Analysis

The breakeven analysis below indicates the approximate dollar returns and percentage required for the redemption value of a hypothetical $50.00 initial investment in a single unit to equal the amount invested twelve months after the investment was made. 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.

Assumed initial selling price per unit |  | $ | 50.00 |
Management Fee (0.75%)(1) |  | $ | 0.38 |
Creation Basket Fee(2) |  | $ | (0.01 | )
Estimated Brokerage Fee (0.14%)(3) |  | $ | 0.07 |
Interest Income (0.06%)(4) |  | $ | (0.03 | )
Independent Directors and Officers’ Fees(5) |  | $ | 0.01 |
Fees and expenses associated with tax accounting and reporting(6) |  | $ | 0.25 |
Amount of trading income (loss) required for the redemption value at the end of one year to equal the initial selling price of the unit |  | $ | 0.67 |
Percentage of initial selling price per unit |  |  | 1.34 | %(7)

| (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 net assets.

| (2) | Authorized Purchasers are required to pay a Creation or Redemption Basket fee of $1,000 for each order they place to create or redeem one or more baskets. An order must be at least one basket, which is 100,000 units. This breakeven analysis assumes a hypothetical investment in a single unit so the Creation Basket fee is $.01 (1,000/100,000).

| (3) | USBO determined this estimate as follows. The breakeven analysis assumes an initial investment by an investor in one unit. Assuming the price of the unit is $50.00, USBO would receive $5,000,000 upon the sale of a Creation Basket (100,000 units multiplied by $50.00). Assuming no change in the settlement price of the contracts, USBO would be required to sell and purchase positions in 71 futures contracts each month to support the Creation Basket ($5,000,000 divided by the total value of a crude oil contract of $69,830 (as of September 9, 2009, the settlement price for crude oil was $69.83)). Assuming futures commission merchants charge approximately $4.00 per crude oil contract for each buy or sale, the monthly futures commission merchant commission charge per contract would be approximately $8.00, and the annual futures commission merchant commission charge per contract would be approximately $96. Assuming no change in the settlement price of the contracts, USBO would sell and buy 71 crude oil contracts each month to support a Creation Basket, which means that USBO’s monthly commission charge per Creation Basket would be approximately $568, and the annual commission charge per Creation Basket would be approximately $6,816 (71 contracts bought and sold * approximately $8.00 per month * 12 months). As a percentage of the total investment of $5,000,000 to support the issuance of the Creation Basket, USBO’s annual commission expense would be approximately 0.14% ($6,816 divided by $5,000,000 per annum).

| (4) | USBO will earn interest on funds it will deposit with the futures commission merchant and the custodian and it estimates that the interest rate will be 0.06% based on the current interest rate on three-month Treasury Bills as of November 30, 2009. The actual rate may vary.

| (5) | The foregoing assumes that the assets of USBO are aggregated with those of the Related Public Funds, that the aggregate fees paid to the independent directors for 2009 equals $477,000, that the allocable portion of the fees borne by USBO will equal one percent of the aggregate assets of USBO and the Related Public Funds, or $4,770 and that USBO will have $30 million in assets.

| (6) | USBO assumed the aggregate costs attributable to tax accounting and reporting to be $150,000. This estimate is based on the experience of the General Partner in its management of similar funds. The number in the break-even table assumes USBO has $30 million in assets.

| (7) | If only the initial creation basket is sold for proceeds of $5 million, the amount of trading income required for the redemption value at the end of one year to equal the initial selling price of one unit would be $1.96 or 3.92% of the initial selling price per unit.

# THE OFFERING

Offering: |  |

|  | USBO will be offering Creation Baskets consisting of 100,000 units through ALPS Distributors, Inc. (“Marketing Agent”) as marketing agent to Authorized Purchasers. The initial Authorized Purchaser will purchase one or more initial Creation Baskets of 100,000 units at an initial offering price per unit equal to $50.00. The initial Authorized Purchaser intends to offer the units of the initial Creation Basket(s) publicly. The effective date will be the date on which the SEC declares the registration statement relating to this prospectus effective and is expected to be the date of the sale of the initial Creation Basket(s). However, the proceeds are not expected to be invested until the order for the first Creation Basket has settled and cash is received from the initial Authorized Purchaser. The units are expected to begin trading on the day following the purchase of the initial Creation Basket(s) by the initial Authorized Purchaser.

Use of Proceeds: |  |

|  | The General Partner will apply substantially all of USBO’s assets toward trading positions in Futures Contracts and other Crude Oil-Related Investments and investing in Treasuries, cash and/or cash equivalents. The General Partner expects to deposit 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 or Other Crude Oil-Related Investments. USBO will use only Treasuries, cash and/or cash equivalents to satisfy these requirements. The General Partner expects that all entities that will hold or trade USBO’s assets will be based in the United States and will be subject to United States regulations. The General Partner believes that 10% to 20% of USBO’s assets will normally be committed as margin for its positions in Futures Contracts. However, from time to time, the percentage of assets committed as margin may be substantially more, or less, than such range. The remaining portion of USBO’s assets, of which the General Partner expects to be the vast majority, will be held in Treasuries, cash and/or cash equivalents by its custodian, Brown Brothers Harriman & Co. (“Custodian”), or posted as collateral to support USBO’s investments in Crude Oil Interests. All interest income earned on these investments will be retained for USBO’s benefit.

NYSE Arca Symbol: |  |

|  | “BNO”

Creation and Redemption: |  |

|  | Authorized Purchasers will pay a $1,000 fee for each order to create or redeem one or more Creation Baskets or Redemption Baskets. Authorized Purchasers will not be required to sell any specific number or dollar amount of units. The per unit price of units offered in Creation Baskets on any day after the effective date of the registration statement relating to this prospectus 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.

TABLE OF CONTENTS

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.

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 Depository Trust Company (“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 banks, brokers, dealers, trust companies and others 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 will be credited to DTC Participants’ securities accounts following confirmation of receipt of payment.

|  | 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 and subtracting any liabilities. Under USBO’s current operational procedures, the Administrator calculates the NAV of USBO’s units 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 will use the ICE Futures Exchange settlement price (a weighted average price of trades during a three minute settlement period from 2:27 p.m. New York time) for the contracts held on the ICE Futures Exchange, but will calculate or determine 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.

|  | The NYSE Arca currently calculates an approximate net asset value every 15 seconds throughout each day USBO’s units are traded on the NYSE Arca for as long as the ICE Futures Exchange’s main pricing mechanism is open.

Fund Expenses: |  |

|  | USBO will pay 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 are estimated to be 0.14% and will be paid to unaffiliated brokers. USBO also pays any licensing fees for the use of intellectual property. Registration fees paid to the SEC, the Financial Industry Regulatory Authority (“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 will be paid by the General Partner, but the fees and expenses associated with subsequent SEC registrations of units will be 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 are expected to equal approximately $477,000 for 2009, though 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 will be paid by the General Partner. The General Partner paid approximately $525,000 on behalf of the Related Public Funds in 2008.

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.

Authorized Purchasers: |  |

|  | We expect the initial Authorized Purchaser to be [TBD]. We expect subsequent Authorized Purchasers to purchase or redeem Creation Baskets or Redemption Baskets, respectively, from or to USBO. A list of Authorized Purchasers will be 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, including USBO’s financial statements and the related notes.

# 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 intends to invest 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 USBO’s units accurately track the percentage changes in the 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.

Tensions with Iran, the world’s fourth largest oil exporter, could put oil exports in jeopardy. Other global concerns include civil unrest and sabotage affecting the flow of oil from Nigeria, a large oil exporter. Meanwhile, friction continues between the governments of the United States and Venezuela, a major exporter of oil to the United States. Additionally, a series of production cuts by members of the Organization of Oil Exporting Countries (“OPEC”) followed by a refusal to subsequently increase oil production have tightened world oil markets.

### 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 such as Saudi Arabia to increase output to make up the difference. In recent years much of that reserve capacity has been absorbed by increased demand. The current global economic downturn, however, has led to a decrease in the demand for oil that is expected to last through the end of 2009 and a corresponding increase in reserve capacities. According to the United States Government’s Energy Information Administration, global oil demand is expected to fall by almost 1.8 million barrels a day in 2009, compared with largely unchanged demand in 2008. Global demand for oil is expected to rise by 0.7 million barrels a

12

TABLE OF CONTENTS

day in 2010. Consumption of oil products continues to increase in certain parts of the world, especially in rapidly growing countries such as India and China, which is now the world’s second-largest energy user. The volatility of demand in the oil market makes it difficult to predict the availability of reserve capacities.

### The price of USBO’s units may be influenced by factors such as the short-term supply and demand for crude oil and the short-term supply and demand for USBO’s units. This may cause the units to trade at a price that is above or below USBO’s NAV per unit. Accordingly, changes in the price of units may substantially vary from the changes in the price of crude oil. If this variation occurs, then you 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.

While it is expected that the trading prices of the units will fluctuate in accordance with the changes in USBO’s NAV, the prices of units may also be influenced by other factors, including the short-term supply and demand for crude oil and the units. There is no guarantee that the units will not trade at appreciable discounts from, and/or premiums to, USBO’s NAV. This could cause the changes in the price of the units to substantially vary from the changes in the price of Brent crude oil. This may be harmful to you because if changes in the price of the units vary substantially from the changes in the Benchmark Futures Contract or the spot price of Brent crude oil, then you may not be able to effectively use USBO as a way to hedge the risk of losses in your crude oil-related transactions or as a way to indirectly invest in crude oil.

### Changes in USBO’s NAV may not correlate with changes in the price of the Benchmark Futures Contract. If this were to occur, you 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 will endeavor to invest USBO’s assets as fully as possible in Futures Contracts and Other Crude Oil-Related Investments so that changes in percentage terms in the NAV will closely correlate with changes in percentage terms in the price of the Benchmark Futures Contract. However, changes in USBO’s NAV may not correlate with changes in the price of the Benchmark Futures Contract for several reasons as set forth below:

| • | USBO (i) may not be able to sell/buy the exact amount of positions in Futures Contracts and Other Crude Oil-Related Investments to have a perfect correlation with NAV; (ii) may not always be able to buy and sell Futures Contracts or Other Crude Oil-Related Investments at the market price; (iii) may not experience a perfect correlation between the Benchmark Futures Contract and the underlying investments in Futures Contracts, Other Crude Oil-Related Investments and Treasuries, cash and cash equivalents; and (iv) is required to pay 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 changes in USBO’s NAV if USBO has fully invested in positions 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. In addition, there are also technical differences between the two markets, e.g., one is a physical market while the other is a futures market traded on exchanges, that may cause variations between the spot price of Brent crude oil and the prices of related futures contracts.

| • | USBO plans to sell and buy only as many positions in Futures Contracts and Other Crude Oil-Related Investments that it can to get the changes in percentage terms of the NAV as close as possible to the changes in percentage terms in the price of the Benchmark Futures Contract. The remainder of its assets will be invested in Treasuries, cash and/or cash equivalents and will be used to satisfy initial margin and additional margin requirements, if any, and to otherwise support its investments in positions in Crude Oil Interests. Investments in Treasuries, cash and/or cash equivalents, both directly and as margin, will provide rates of return that will vary from changes in the value of the spot price of Brent crude oil and the price of the Benchmark Futures Contract.

| • | In addition, because USBO will incur certain expenses in connection with its investment activities, and will hold 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

13

TABLE OF CONTENTS

|  | Partner will not be 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 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 positions in three Benchmark Futures Contracts and it needs to invest in four contracts to track the price of Brent crude oil then the correlation will be lower, but if it takes positions in 20,000 Benchmark Futures Contracts and it needs to invest in 20,001 contracts then the correlation will be higher. At certain asset levels, USBO may be limited in its ability to sell or purchase positions in the Benchmark Futures Contract or other Futures Contracts due to accountability levels imposed by the relevant exchanges. To the extent that USBO takes positions 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 sell or buy the exact number of positions in Futures Contracts and Other Crude Oil-Related Investments to have a perfect correlation with the Benchmark Futures Contract if the purchase price of the positions in 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 positions (for example, assume USBO receives $5,000,000 for the sale of a Creation Basket and assume that the value of the position in a Futures Contract for crude oil is $49,410 based on a price of $49.41 per barrel, then USBO could only invest in only 101 positions in such Futures Contracts with an aggregate value of $4,990,410), 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 contract was 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 sell or purchase these investments at the last reported price for such investments.

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

### The Benchmark Futures Contract may not correlate with the spot price of Brent crude oil and this could cause the changes in the price of units to substantially vary from the changes in the spot price of Brent crude oil. If this were to occur, then you 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.

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 the price of units may not accurately track the price movements of Brent crude oil and you may not be able to effectively use USBO as a way to hedge the risk of losses in your crude oil-related transactions or as a way to indirectly invest in crude oil.

### 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.

14

TABLE OF CONTENTS

This loss may adversely impact the price of the units and may decrease the correlation between the price of the units, the price of USBO’s positions in Futures Contracts 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 price fluctuation limits, may contribute to a lack of liquidity with respect to some Crude Oil Interests.

Unexpected market illiquidity may cause major losses to investors at any time or from time to time. In addition, USBO does not intend at this time to establish a credit facility, which would provide an additional source of liquidity, but instead will rely 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. 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.

### 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 will influence 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 make 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 make physical delivery of crude oil under its Futures Contracts, futures contracts are not required to be cash-settled and it is possible to take delivery under 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 NAV, may change as well.

### The price relationship between the near month contract 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 other crude oil price indices’ total returns.

The Benchmark Futures Contract is the near month contract to expire until the near month contract is within two weeks of expiration, when it is sold and near month contract is replaced with the next month contract to expire. In the event of a crude oil futures market where near month contracts trade at a higher price than next month contracts to expire, 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 Futures Contract would tend to rise as it approaches expiration. As a result positions in 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 to expire, 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 positions in 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 NAV to vary significantly. In the event of a prolonged period of contango, and absent the impact of rising or falling crude oil prices, this could have a significant negative impact on USBO’s NAV and total return.

### 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 FSA, 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 futures transactions in the United Kingdom and the United States is a rapidly changing area of law and is subject to modification by government and judicial action.

The regulation of commodity interest transactions in the United Kingdom and 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 which are publicly distributed in the United States. There is a possibility of future regulatory changes altering, perhaps to a material extent, the nature of an investment in USBO or the ability of USBO to continue to implement its investment strategy. In addition, various national governments 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 could be substantial and adverse.

In the wake of the economic crisis last year, the Administration, federal regulators and Congress are revisiting the regulation of the financial sector, including securities and commodities markets. These efforts are likely to result in significant changes in the regulation of these markets.

Currently, a number of proposals that would alter the regulation of Crude Oil Interests are being considered by federal regulators and Congress. These proposals include the imposition of fixed position limits on energy-based commodity futures contracts, extension of position and accountability limits to futures contract on non-U.S. exchanges previously exempt from such limits, and the forced use of clearinghouse mechanisms for all over-the-counter transactions. Certain proposals would aggregate and limit all positions in energy futures held by a single entity, whether such positions exist on U.S. futures exchange, non-U.S. futures exchanges, or in over-the-counter contracts. While it cannot be predicted at this time what reforms will eventually be made or how they will impact USBO, if any of the aforementioned proposals are implemented, USBO’s ability to meet its investment objective may be negatively impacted and investors could be adversely affected.

TABLE OF CONTENTS

### If you are investing in USBO for purposes of hedging, you might 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 using USBO units, the hedger may be concerned that the hedged item will increase in price, but must recognize the risk that the price may instead decrease 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.

In addition, if the hedge is not a perfect one, the hedger can lose on the hedging transaction and not realize an offsetting gain in the value of the underlying item being hedged.

When using futures contracts as a hedging technique, at best, the correlation between changes in prices of futures contracts and of the items being hedged can be only approximate. The degree of imperfection of correlation depends upon circumstances such as: variations in speculative markets, demand for futures and for crude oil products, technical influences in futures trading, and differences between anticipated energy costs being hedged and the instruments underlying the standard futures contracts available for trading. Even a well-conceived hedge may be unsuccessful to some degree because of unexpected market behavior as well as the expenses associated with creating the hedge.

In addition, using an investment in USBO as a hedge for changes in energy costs (e.g., investing in heating oil, crude oil, gasoline, natural gas, or other fuels, or electricity) may not correlate because changes in the spot price of crude oil may vary from changes in energy costs because the spot price may not be at the same rate as changes in the price of other energy products and, in any case, the price of crude oil does not reflect the refining, transportation, and other costs that may impact the hedger’s energy costs.

### An investment in USBO may provide you little or no diversification benefits. Thus, in a declining market, USBO may have no gains to offset your losses from other investments, and you may suffer losses on your investment in USBO at the same time you incur 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, you will obtain little or no diversification benefits from an investment in the units. In such a case, USBO may have no gains to offset your losses from other investments, and you may suffer losses on your investment in USBO at the same time you incur losses with respect to other investments.

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 you do not have the protections of the Investment Company Act of 1940.

USBO is not an investment company subject to the Investment Company Act of 1940. Accordingly, you 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.

### USBO has no operating history so there is no performance history to serve as a basis for you to evaluate an investment in USBO.

USBO is new and has no operating history. Therefore, you do not have the benefit of reviewing the past performance of USBO as a basis to evaluate an investment in USBO. The General Partner’s current experience involves managing USOF, an exchange traded security that invests primarily in Futures Contracts for light, sweet crude oil, Treasuries, cash and/or cash equivalents; USNG, an exchange traded security that invests primarily in Futures Contracts for natural gas, Treasuries, cash and/or cash equivalents; US12OF, an exchange traded security that invests primarily in Futures Contracts for light, sweet crude oil, Treasuries, cash and/or cash equivalents; UGA, an exchange traded security that invests primarily in Futures Contracts for gasoline, Treasuries, cash and/or cash equivalents; USHO, an exchange traded security that invests primarily in Futures Contracts for heating oil, Treasuries, cash and/or cash equivalents; USSO, an exchange traded security that invests primarily in short positions in Futures Contracts for crude oil, Treasuries, cash and/or cash equivalents; and US12NG, an exchange traded security that invests primarily in Futures Contracts for natural gas, Treasuries, cash and/or cash equivalents. However, there are significant differences between operating funds which attempt to track the returns of US-based crude oil, natural gas, gasoline or heating oil and operating a fund that is attempting to track the crude oil futures market based in the United Kingdom. The General Partner’s results with the crude oil, natural gas, gasoline and heating oil funds may not be representative of results that may be experienced with an fund investing in non-U.S. crude oil futures.

### 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 Mr. Nicholas Gerber, Mr. Ray Allen and Mr. John Hyland. If Mr. Gerber, Mr. Allen or Mr. 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, Mr. Gerber and Mr. Hyland are involved in the management of the Related Public Funds. In addition, Mr. Allen is involved in the management of UGA, USHO, USSO and US12NG. Mr. Gerber is also employed by Ameristock Corporation, a registered investment adviser that manages a public mutual fund. It is estimated that Mr. Gerber will spend approximately 50% of his time on fund matters. Mr. Allen will spend approximately 100% of his time on fund matters and Mr. Hyland will spend approximately 85% of his time on fund matters. To the extent that the General Partner establishes additional funds, even greater demands will be placed on Mr. Gerber, Mr. Allen and Mr. Hyland, as well as the other officers of the General Partner, including Mr. Howard Mah, the Chief Financial Officer, and its Board of Directors.

### 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 you 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.

The Benchmark Futures Contract is currently traded on the ICE Futures Exchange without specific accountability levels or position limits. However, the ICE Futures Exchange’s daily position management regime requires that any position greater than 500 contracts in the nearest two months to expire must be reported to the ICE Futures Exchange on a daily basis. The ICE Futures Exchange has powers to prevent the development of excessive positions or unwarranted speculation or any other undesirable situation and may take any steps necessary to resolve such situations including the ability to mandate limitations on the size of such positions or to reduce positions where appropriate. Although the Benchmark Futures Contract is not

18

TABLE OF CONTENTS

subject to the more stringent accountability levels and position limits established by U.S. designated contract markets (discussed below), recent actions by the ICE Futures Exchange indicate that the exchange is actively using its oversight authority to regulate positions in its contracts.

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. For example, the current accountability level for investments at any one time in light, sweet crude oil Futures Contracts is 20,000. While this is not a fixed ceiling, it is a threshold above which the NYMEX may exercise greater scrutiny and control over an investor, including limiting an investor to holding no more than 20,000 light, sweet crude oil Futures Contracts. With regard to position limits, the NYMEX limits an investor from holding more than 3,000 net futures in the last 3 days of trading in the near month contract to expire.

In addition to accountability levels and position limits, the NYMEX also sets daily price fluctuation limits on futures contracts. The daily price fluctuation limit establishes the maximum amount that the price of futures contracts 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.

For example, the NYMEX imposes a $10.00 per barrel ($10,000 per contract) price fluctuation limit for light, sweet crude oil Futures Contracts. This limit is initially based off of the previous NYMEX trading day’s settlement price. If any light, sweet crude oil Futures Contract is traded, bid, or offered at the limit for five minutes, trading is halted for five minutes. When trading resumes it begins at the point where the limit was imposed and the limit is reset to be $10.00 per barrel in either direction of that point. If another halt were triggered, the market would continue to be expanded by $10.00 per barrel in either direction after each successive five-minute trading halt. There is no maximum price fluctuation limit during any one trading session.

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 you 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 is not limiting the size of the 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 ICE Futures Exchange, it may then, if permitted under applicable regulatory requirements, purchase Futures Contracts on the NYMEX or other exchanges that trade listed crude oil futures. The Futures Contracts available on the NYMEX are comparable to the contracts on the ICE Futures Exchange, but they may have different underlying commodities, sizes, deliveries, and prices.

### There are technical and fundamental risks inherent in the trading system the General Partner intends to employ.

The General Partner’s trading system is quantitative in nature and it is possible that the General Partner might make a mathematical error. In addition, it is also possible that a computer or software program may malfunction and cause an error in computation.

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

Spreads combine simultaneous long and short positions in related futures contracts that differ by commodity (e.g., long crude oil and short gasoline), by market (long crude oil futures, short Brent crude oil futures), or by delivery month (long December, short November). Spreads gain or lose value as a result of relative changes in price between the long and short positions. Spreads often reduce risk to investors, because the contracts tend to move up or down together. However, both legs of the spread could move against an investor simultaneously, in which case the spread would lose value. Certain types of spreads may face unlimited risk because the short contract can increase by an unlimited amount and the investor would have to take delivery or offset at any price.

19

TABLE OF CONTENTS

A commodity straddle takes both long and short option positions in the same commodity in the same market and delivery month simultaneously. The buyer of a straddle profits if either the long or the short leg of the straddle moves further than the combined cost of both options. The seller of a straddle profits if both the long and short positions do not trade beyond a range equal to the combined premium for selling both options.

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 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 your detriment.

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’ NAV track changes in the price of 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’s 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 invest 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 your best interests. 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 the Related Public Funds, as well as USBO, and will serve as the general partner for US12NG, if such fund offers securities to the public or begins 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 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 you could lose your investment.

### 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.

Unitholders that have not applied to become limited partners have no voting rights, other than to remove the General Partner. Limited partners will have limited voting rights with respect to USBO’s affairs. 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.

20

TABLE OF CONTENTS

### 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.

### USBO could terminate at any time and cause the liquidation and potential loss of your investment and could upset the overall maturity and timing of your investment portfolio.

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, withdrawal, or removal of the General Partner could cause USBO to terminate unless a majority in 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 your investment. Termination could also negatively affect the overall maturity and timing of your investment portfolio.

### Limited partners may not 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 our 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 our capital securities representing limited partnership interests. However, a limited partner may be required to repay to us any amounts wrongfully returned or distributed to it under some circumstances. Under Delaware law, we may not make a distribution to limited partners if the distribution causes our liabilities (other than liabilities to partners on account of their partnership interests and nonrecourse liabilities) to exceed the fair value of our 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’s existing units are, and any units USBO issues in the future will be, subject to restrictions on transfer. Failure to satisfy these requirements will preclude you from being able to have all the rights of a limited partner.

No transfer of any unit or interest therein may 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 authority with jurisdiction over such transfer, or (b) cause USBO to be taxable as a corporation or affect USBO’s existence or qualification as a limited partnership. In addition, investors may only become limited partners if they transfer their units to purchasers that meet certain conditions outlined in the LP Agreement, which provides that each record holder or limited partner or unitholder applying to become a limited partner (each a record holder) may be required by the General Partner 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 its ownership would

21

TABLE OF CONTENTS

subject USBO to the risk of cancellation or forfeiture of any of its assets under any federal, state or local law or regulation. All purchasers of USBO’s units, who wish to become limited partners or 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. Any transfer of units will not be recorded by the transfer agent or recognized by us unless a completed transfer application is delivered to the General Partner or the Administrator. 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, our units will be securities and will be transferable according to the laws governing transfers of securities. See “Transfer of Units.”

### USBO does not expect to make cash distributions.

The General Partner intends to re-invest any realized gains in 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. 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. 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.

### 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 expects to pay brokerage charges of approximately 0.14% (including futures commission merchant fees of $4.00 per buy or sell), any licensing fees for the use of intellectual property, registration fees with the SEC, FINRA, or other regulatory agency in connection with offers and sales of the units subsequent to the initial offering of the units including the legal, printing, accounting and other expenses associated therewith. USBO also pays the fees and expenses, including directors and officers liability insurance, of the independent directors, management fees of 0.75% of NAV on its average net assets, tax accounting and reporting costs, and over-the-counter spreads and extraordinary expenses (i.e., 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 can not 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.

### USBO, to date, has depended upon the General Partner to pay all its expenses. If this offering of units does not raise sufficient funds to pay USBO’s future expenses, the General Partner no longer pays such expenses and no other source of funding of expenses is found, USBO will terminate and investors may lose all or part of their investment.

To date, all of USBO’s expenses have been funded by the General Partner. If the General Partner and USBO are unsuccessful in raising sufficient funds to cover its expenses or in locating any other source of funding, USBO will terminate and investors may lose all or part of their investment.

22

TABLE OF CONTENTS

### 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 level of capacity at such time. 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 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 recession and USBO does not expect these conditions to improve in the near future.

Currently and throughout 2008, the financial markets have experienced very difficult conditions and volatility as well as significant adverse trends. The deteriorating 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. A continued recession or a depression could adversely affect the financial condition and results of operations of USBO’s service providers and Authorized Purchasers which would impact the ability of the General Partner to achieve USBO’s investment objective.

### The failure or bankruptcy of a clearing broker could result in a substantial loss of USBO’s assets the clearing broker could be subject to proceedings that impair its ability to execute USBO’s trades.

Under CFTC regulations, a clearing broker maintains customers’ assets in a bulk segregated account. If a clearing broker fails to do so, or is unable to satisfy a substantial deficit in a customer account, its 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 expected to be held in Treasuries, cash and/or cash equivalents with USBO’s 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.

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.

TABLE OF CONTENTS

### The failure or insolvency of USBO’s custodian could result in a substantial loss of USBO’s assets.

As noted above, the vast majority of USBO’s assets are held in Treasuries, cash and/or cash equivalents with USBO’s 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 pending for USBO’s business method and it is registering 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 have difficulty 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 anticipates using 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 anticipates using 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. Execution of the formulas and operation of the systems are subject to human error. Any failure, inaccuracy or delay in implementing any of the formulas or systems 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.

### USBO may experience substantial losses on transactions if the computer or communications system fails.

USBO’s trading activities, including its risk management, depend on the integrity and performance of the computer and communications systems supporting them. 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.

### If the computer and communications systems are not upgraded, USBO’s financial condition could be harmed.

The development of complex computer and communications systems and new technologies may render the existing computer and communications systems supporting USBO’s trading activities obsolete. In addition, these computer and communications systems must be compatible with those of third parties, such as the

24

TABLE OF CONTENTS

systems of exchanges, clearing brokers and the executing brokers. As a result, if these third parties upgrade their systems, the General Partner will need to make corresponding upgrades to continue effectively its trading activities. USBO’s future success will depend on USBO’s ability to respond to changing technologies on a timely and cost-effective basis.

### USBO depends on the reliable performance of the computer and communications systems of third parties, such as brokers and futures exchanges, and may experience substantial losses on transactions if they fail.

USBO depends on the proper and timely function of complex computer and communications systems maintained and operated by the futures exchanges, brokers and other data providers that the General Partner uses to conduct trading activities. Failure or inadequate performance of any of these systems could adversely affect the General Partner’s ability to complete transactions, including its ability to close out positions, and result in lost profit opportunities and significant losses on commodity interest transactions. This could have a material adverse effect on revenues and materially reduce USBO’s available capital. For example, unavailability of price quotations from third parties may make it difficult or impossible for the General Partner to use its proprietary software that it relies upon to conduct its trading activities. Unavailability of records from brokerage firms may make it difficult or impossible for the General Partner to accurately determine which transactions have been executed or the details, including price and time, of any transaction executed. This unavailability of information also may make it difficult or impossible for the General Partner to reconcile its records of transactions with those of another party or to accomplish settlement of executed transactions.

### 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. The terrorist attacks of September 11, 2001 and the war in Iraq, global anti-terrorism initiatives and political unrest in the Middle East and Southeast Asia continue to fuel this concern.

# Risk of Leverage and Volatility

### If the General Partner permits USBO to become leveraged, you could lose all or substantially all of your 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 face 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 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;

| • | domestic and foreign governmental regulations and taxes;

25

TABLE OF CONTENTS

| • | 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 Petroleum Exporting Countries (“OPEC”) to agree upon and maintain oil prices and production levels;

| • | the price and availability of alternative fuels; and

| • | the impact of energy conservation efforts.

### The impact of environmental and other governmental laws and regulations may affect the price of crude oil.

Environmental and other governmental laws and regulations have increased the costs to plan, design, drill, install, operate and abandon oil wells. Other laws have prevented exploration and drilling of crude oil in certain environmentally sensitive federal lands and waters. Several environmental laws that have a direct or an indirect impact on the price of crude oil include, but are not limited to, the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act, and the Comprehensive Environmental Response, Compensation and Liability Act of 1980.

### The limited method for transporting and storing crude oil may cause the price of crude oil to increase.

Crude oil is transported throughout the United Kingdom and the United States by way of pipelines, barges, tankers, trucks and rail cars and is stored in aboveground and underground storage facilities. These systems may not be adequate to meet demand, especially in times of peak demand or in areas of the United Kingdom or the United States where crude oil service is already limited due to minimal pipeline and storage infrastructure. As a result of the limited method for transporting and storing crude oil, the price of crude oil may increase.

# Over-the-Counter Contract Risk

### Over-the-counter transactions are subject to little, if any, regulation.

A portion of USBO’s assets may be used to trade over-the-counter crude oil interest contracts, such as forward contracts or swap or spot contracts. Over-the-counter contracts are typically traded on a principal-to-principal basis through dealer markets that are dominated by major money center and investment banks and other institutions and are essentially unregulated by the CFTC. You therefore do not receive the protection of CFTC regulation or the statutory scheme of the Commodity Exchange Act in connection with this trading activity by USBO. The markets for over-the-counter contracts rely upon the integrity of market participants in lieu of the additional regulation imposed by the CFTC on participants in the futures markets. The lack of regulation in these markets could expose USBO in certain circumstances to significant losses in the event of trading abuses or financial failure by participants.

### 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 also 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.

26

TABLE OF CONTENTS

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

Over-the-counter contracts may have terms that make them less marketable than Futures 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 diminish the ability to realize the full value of such contracts.

# Risk of Trading in International Markets

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

The General Partner expects to invest primarily in Futures Contracts, a significant portion of which will be outside United States exchanges including the ICE Futures Exchange. Some non-U.S. markets present risks because they are not subject to the same degree of regulation as their U.S. counterparts. None of the CFTC, NFA, or any domestic exchange regulates activities of any foreign boards of trade or exchanges, including the execution, delivery and clearing of transactions, nor has the power to compel enforcement of the rules of a foreign board of trade or exchange or of any applicable non-U.S. laws. However, the CFTC does have some oversight authority and the ability to impose certain self-regulatory and reporting requirements on non-U.S. futures exchanges trading U.S.-linked futures contracts and contracts with a significant price discovery function.

Additonally, 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.

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 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 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. 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. Futures Contract, option on any non-U.S. Futures Contract or non-U.S. Other Crude Oil Interest, and, therefore, the potential profit and loss on such Crude Oil Interests, 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 also 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 General Partner bases its strategies may not be as reliable or accessible as it is for U.S. exchanges.

# Tax Risk

Please refer to “U.S. Federal Income Tax Considerations” for information regarding the U.S. federal income tax consequences of the purchase, ownership and disposition of units.

### Your tax liability may exceed the amount of distributions, if any, on your units.

Cash or property will be distributed at the sole discretion of the General Partner. 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.

### Your allocable share of taxable income or loss may differ from your economic income or loss on your units.

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

### Items of income, gain, deduction, loss and credit with respect to units could be reallocated if the U.S. Internal Revenue Service does not accept the assumptions and conventions applied by USBO in allocating those items, with potential adverse consequences for you.

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 will apply 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 (“Code”) and applicable Treasury Regulations, however, and it is possible that the U.S. Internal Revenue Service, or the IRS, will successfully challenge our allocation methods and require us to reallocate items of income, gain, deduction, loss or credit in a manner that adversely affects you. If this occurs, you may be required to file an amended tax return and to pay additional taxes plus deficiency interest.

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

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

except upon approval by the affirmative vote of the holders of at least 66 2/3% of our outstanding limited partner interests (excluding limited partner interests owned 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, which is comprised of four 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. The General Partner 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. The board of directors has determined that each member of the audit committee meets the financial literacy requirements of the NYSE Arca and the audit committee charter. The board of directors has further determined that each of Messrs. Ellis and Fobes have accounting or related financial management expertise, as required by the NYSE Arca, such that each of them is considered an “Audit Committee Financial Expert” as such term is defined in Item 407(d)(5) of Regulation S-K.

Mr. Nicholas Gerber and Mr. Howard Mah also 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.

Draw-down: Losses experienced by the fund 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.

## Other Related Commodity Trading and Investment Management Experience

Ameristock Corporation is an affiliate of the General Partner and it is a California-based registered investment advisor registered under the Investment Advisors Act of 1940, as amended, that has been sponsoring and providing portfolio management services to mutual funds since 1995. Ameristock Corporation is the investment adviser to the Ameristock Mutual Fund, Inc., a mutual fund registered under the Investment Company Act of 1940 that focuses on large cap U.S. equities that had approximately $218.1 million in assets as of November 30, 2009. 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 is in the process of winding up its affairs.

## How Does USBO Operate?

The net assets of USBO will consist primarily of investments in futures contracts for Brent crude oil, but may also consist of other types of crude oil, natural gas, gasoline, heating oil and other petroleum-based fuels traded on the ICE Futures Exchange, NYMEX, or other U.S. and foreign exchanges (collectively, “Futures Contracts”). USBO may also invest in 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”). 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 will invest 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 will be investing in Futures Contracts and the management of 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 to have the daily changes in percentage terms of the units’ net asset value reflect the daily changes in percentage terms of the spot price of Brent crude oil as measured by the 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. 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.

As a specific benchmark, the General Partner will endeavor 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.

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

The Benchmark Futures Contract will be changed from the near month contract to the next month contract over a four-day period. Each month, the Benchmark Futures Contract will change starting at the end of the day on the date two weeks prior to expiration of the near month contract for that month. During the first three days of the period, the applicable value of the Benchmark Futures Contract will be based on a combination of the near month contract and the next month contract as follows: (1) day 1 will consist of 75% of the

49

TABLE OF CONTENTS

then near month contract’s total return for the day, plus 25% of the total return for the day of the next month contract, (2) day 2 will consist of 50% of the then near month contract’s total return for the day, plus 50% of the total return for the day of the next month contract, and (3) day 3 will consist of 25% of the then near month contract’s total return for the day, plus 75% of the total return for the day of the next month contract. On day 4, the Benchmark Futures Contract will be the next month contract to expire at that time and that contract will remain the Benchmark Futures Contract until the beginning of 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 oil investments by closing, or selling, a percentage of USBO’s positions in oil interests and reinvesting the proceeds from closing those positions in new oil interests that reflect the change in the Benchmark Futures Contract.

The anticipated monthly dates on which the Benchmark Futures Contract will be changed and the Crude Oil Interests will be “rolled” in 2010 and subsequent years will be posted on USBO’s website at www.unitedstatesbrentoilfund.com, and will be subject to change without notice.

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

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 will employ a “neutral” investment strategy intended to track 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 taking positions indirectly in Brent crude oil in a cost-effective manner, and/or to permit participants

50

TABLE OF CONTENTS

in the crude oil or other industries to hedge the risk of losses in their crude oil-related transactions. Accordingly, depending on the investment objective of an individual investor, the risks generally associated with taking positions in 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 Benchmark Futures Contract.

USBO’s total portfolio composition will be disclosed each day that the NYSE Arca is open for trading, on USBO’s website at www.unitedstatesbrentoilfund.com. The website disclosure of portfolio holdings will be made daily and will include, as applicable, the name and value of each Crude Oil Interest, the specific types of Other Crude Oil-Related Investments and characteristics of such Other Crude Oil-Related Investments, Treasuries, and the amount of cash and/or cash equivalents held in USBO’s portfolio. USBO’s website is publicly accessible at no charge. USBO’s assets will be held in segregated accounts pursuant to the Commodity Exchange Act and CFTC regulations.

USBO will create and redeem units only in blocks of 100,000 units called Creation Baskets and Redemption Baskets, respectively. Only Authorized Purchasers may purchase or redeem Creation Baskets or Redemption Baskets. 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. It is expected that baskets will be created when there is sufficient demand for units that 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 Baskets 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, it is expected that baskets will be 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 are expected to 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.

The minimum number of Creation Baskets that must be sold is one. All proceeds from the sale of Creation Baskets will be invested as quickly as possible in the investments described in this prospectus. There will be no escrow or similar holding of funds that has a time period or other conditions. Investments will be held through the Custodian or through accounts with USBO’s commodity futures brokers. There is no stated maximum time period for USBO’s operations and the fund will continue until all units are redeemed or the fund is liquidated pursuant to the terms of the LP Agreement.

There is no specified limit on the maximum amount of Creation Baskets that can be sold. At some point, accountability levels on certain of the Futures Contracts in which USBO intends to invest may practically limit the maximum amount 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.

While USBO will issue units only in Creation Baskets, units may also be purchased and sold in much smaller increments on the NYSE Arca. These transactions, however, will be effected at bid and ask prices established by specialist firm(s). Like any listed security, units can be purchased and sold at any time a secondary market is open.

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. These correlations are relevant because the General Partner endeavors to invest USBO’s assets in Futures Contracts and Other Oil Interests 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 certain other fuel-based commodity futures contracts do not closely correlate with the Futures Contracts then their use could lead to greater tracking error. 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

51

TABLE OF CONTENTS

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.

The degree of correlation varies both among the different commodities and also varies over time. As such, the use of an energy related commodity to hedge a different energy commodity can only produce, at best, an imperfect hedge. The following price graph is scaled so all contracts start at the same level at year end 1998.

## What Is USBO’s Investment Strategy?

In managing USBO’s assets the General Partner does not intend to use a technical trading system that issues buy and sell orders. The General Partner does intend to employ a quantitative methodology whereby each time a Creation Basket is sold, the General Partner will take corresponding positions in 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 from the sale 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 $50.00. In that case, USBO would receive $5,000,000 in proceeds from the sale of the Creation Basket ($50 NAV per unit multiplied by 100,000 units, and ignoring the Creation Basket fee of $1,000). If one were to assume further that the General Partner wants to invest the entire proceeds from the Creation Basket in positions in the Benchmark Futures Contract and that the market value of the Benchmark Futures Contract is $141,370, USBO would be unable to sell the exact number of Benchmark Futures Contracts with an aggregate market value equal to $5,000,000. Instead, USBO would be able to buy 35 Benchmark Futures Contracts with an aggregate face amount of $4,947,750. Assuming a margin requirement equal to 10% of the value of the Benchmark Futures Contract, USBO would be required to deposit $494,775 in Treasuries and cash with the

52

TABLE OF CONTENTS

futures commission merchant through which the Benchmark Futures Contracts were sold. The remainder of the proceeds from the sale of the Creation Basket 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.

The specific Futures Contracts to be sold will 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 anticipates significant investments in ICE Futures Exchange futures contracts, as USBO reaches certain position limits on the ICE Futures Exchange, or for other reasons, it will invest in Futures Contracts traded on other exchanges or invest in Other Crude Oil-Related Investments such as contracts in the “over-the-counter” market.

The General Partner does not anticipate letting its Futures Contracts expire and making delivery of the underlying crude oil. Instead, the General Partner will close existing positions e.g., when it changes the Benchmark Futures Contract or it otherwise determines it would be appropriate to do so and reinvest the proceeds in new Futures Contracts. 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 closely track the changes in percentage terms in the prices of the futures contracts in which USBO invests. The General Partner believes that certain arbitrage opportunities will result in the price of the units traded on the NYSE Arca closely tracking the NAV of USBO. Additionally, as discussed above, the General Partner has conducted research that indicates that Futures Contracts traded on the ICE Futures Exchange have closely tracked the spot price of the underlying oil. Based on these expected interrelationships, the General Partner believes that the changes in the price of USBO’s units as traded on the NYSE Arca will closely track the 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 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. For example, Brent crude oil Futures Contracts traded on the ICE Futures Exchange trade in units of 1,000 barrels. The Brent crude oil Futures Contracts traded on the ICE Futures Exchange are priced by an electronic, screen-based system that determines the price by matching electronically offers to purchase and sell.

Certain typical and significant characteristics of Futures Contracts are discussed below. Additional risks of investing in or taking positions in Futures Contracts are included in “What are the Risk Factors Involved with an Investment in USBO?”

Impact of Exchange Regulation, Accountability Levels, Position Limits and Price Fluctuation Limits. The Benchmark Futures Contract is currently traded on the ICE Futures Exchange without specific accountability levels or position limits. However, the ICE Futures Exchange’s daily position management regime requires that any position greater than 500 contracts in the nearest two months to expire must be reported to the ICE Futures Exchange on a daily basis. The ICE Futures Exchange has powers to prevent the development of excessive positions or unwarranted speculation or any other undesirable situation and may take any steps necessary to resolve such situations including the ability to mandate limitations on the size of such positions or to reduce positions where appropriate. Although the Benchmark Futures Contract is not subject to the same accountability levels and position limits established by U.S. designated contract markets, recent actions by the ICE Futures Exchange indicate that the exchange is actively using its oversight authority to regulate positions in its contracts.

If USBO is required to limit or reduce the size of its positions in Brent crude oil contracts on the ICE Futures Exchange, it may then, if permitted under applicable regulatory requirements, purchase Futures Contracts on the NYMEX or other exchanges that trade listed crude oil futures. The Futures Contracts available on the NYMEX are comparable to the contracts on the ICE Futures Exchange, but they may have

53

TABLE OF CONTENTS

different underlying commodities, sizes, deliveries, and prices. In addition, the Futures Contracts available on the NYMEX may be subject to accountability levels and position limits.

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. futures exchanges, such as the NYMEX, limit the daily price fluctuation for futures contracts. Currently the ICE Futures Exchange imposes position and accountability limits that are similar to those imposed by the NYMEX for all of its U.S.-linked futures and options contracts, but does not limit the maximum daily price fluctuation.

The accountability levels for the Futures Contracts traded on 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 light, sweet crude oil Futures Contracts is 20,000 contracts. If USBO exceeds this accountability level for positions in light, sweet crude oil Futures Contracts, the NYMEX will monitor USBO’s exposure and may ask for further information on USBO’s activities including the total size of all positions, investment and trading strategy, and the extent of USBO’s liquidity resources. If deemed necessary by the NYMEX, it could also order USBO to reduce its position back to the accountability level.

If the ICE Futures Exchange or the NYMEX orders USBO to reduce its position back to a level that the ICE Futures Exchange or NYMEX deems appropriate for USBO, such a position level may impact the mix of investments in Crude Oil Interests made by USBO. To illustrate, assume that the Benchmark Futures Contract and the unit price of USBO are each $100, and that the ICE Futures Exchange has determined that USBO may not own more than 20,000 Benchmark Futures Contracts. In such case, USBO could invest up to $2 billion of its daily net assets in the Benchmark Futures Contract (i.e., $100 per contract multiplied by 1,000 (a Benchmark Futures Contract is a contract for 1,000 barrels) multiplied by 20,000 contracts) before reaching the position level imposed by the ICE Futures Exchange. Once the daily net assets of the portfolio exceed $2 billion in the Benchmark Futures Contract, the portfolio may not be able to take any further positions in the Benchmark Futures Contract, depending on whether the ICE Futures Exchange imposes limits. If the ICE Futures Exchange does impose limits at the $2 billion level (or another level), USBO anticipates that it will invest the majority of its assets above that level in a mix of other Futures Contracts or Other Crude Oil-Related Investments.

In addition to accountability levels, 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 beginning two weeks from expiration of the contract.

U.S. futures exchanges, including the NYMEX, also limit the amount of price fluctuation for Futures Contracts. For example, the NYMEX imposes a $10 per barrel ($10,000 per contract) price fluctuation limit for light, sweet crude oil Futures Contracts. This limit is initially based off of the previous trading day’s settlement price. If any light, sweet crude oil Futures Contract is traded, bid, or offered at the limit for five minutes, trading is halted for five minutes. When trading resumes it begins at the point where the limit was imposed and the limit is reset to be $10.00 per barrel in either direction of that point. If another halt were triggered, the market would continue to be expanded by $10.00 per barrel in either direction after each successive five-minute trading halt. There is no maximum price fluctuation limit during any one trading session.

USBO anticipates that to the extent it invests in Futures Contracts other than Brent crude oil contracts (such as futures contracts for light, sweet crude oil, natural gas, heating oil, and gasoline) 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 Contracts.

There will be no maximum price fluctuation limits during any one trading session.

Price Volatility. Despite daily price limits, 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 of crude oil and other energy products 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. These economic factors include changes in interest rates; governmental, agricultural, trade, fiscal, monetary and exchange control programs and policies; weather and climate conditions; changing supply and demand relationships; changes in balances of payments and trade; U.S. and international rates of inflation; currency devaluations and revaluations; U.S. and international political and economic events; and changes in philosophies and emotions of market participants. Because USBO will invest a significant portion of its assets in positions 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.

## What Is the Crude Oil Market and the Petroleum-Based Fuel Market?

USBO may purchase Futures Contracts traded on the ICE Futures Exchange that are based on Brent crude oil. It may also purchase contracts on other exchanges, including NYMEX and the Singapore Exchange. The contracts provide for delivery of several grades of domestic and internationally traded foreign crudes, and, among other things, serve the diverse needs of the physical market. In Europe, Brent crude oil is the standard

56

TABLE OF CONTENTS

for futures contracts and is primarily traded on the ICE Futures Exchange. Brent crude oil is the price reference for two-thirds of the world’s traded oil. The ICE Brent Futures is a deliverable contract with an option to cash settle which trades in units of 1,000 barrels (42,000 U.S. gallons). The ICE Futures Exchange also offers a WTI Futures contract which trades in units of 1,000 barrels. The WTI Futures contract is cash settled against the prevailing market price for U.S. light, sweet crude oil.

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 exhibited periods of significant volatility.

Heating Oil. Heating oil, also known as No. 2 fuel oil, accounts for 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 center. The price of heating oil has historically been volatile.

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 million British thermal units 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.

## Why Does USBO Purchase and Sell Futures Contracts?

The investment objective of USBO is to have the daily changes in percentage terms of its units’ NAV reflect the daily changes in percentage terms of the spot price of Brent crude oil as measured by the 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. 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.

Other than investing in Futures Contracts and Other Crude Oil-Related Investments, USBO will only invest in assets to support these investments in Crude Oil Interests. At any given time, a significant majority of USBO’s investments will be in 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 sale or purchase of a Futures Contract with a stated value of $10 million would not require USBO to receive or pay $10 million upon entering into the contract; rather, only a margin deposit, generally of 10% to 20% of

57

TABLE OF CONTENTS

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, USBO expects that 10% to 20% of its assets will be held as margin in segregated accounts with a futures commission merchant. In addition to the Treasuries and cash it posts with the futures commission merchant for the Futures Contracts it owns, USBO will hold 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 intends to earn interest income from the Treasuries and/or cash equivalents that it will purchase, and on the cash it holds through the Custodian. It anticipates that the earned interest income will increase the NAV and limited partners’ capital contribution accounts. USBO plans to reinvest the earned interest income, hold it in cash, or use it to pay its expenses. If USBO reinvests the earned interest income, it will make investments that are consistent with its investment objectives.

Term Structure of 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 crude oil futures contracts and “rolling” those contracts forward each month is the price relationship between the current near month contract and the later month contracts. 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 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 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 holding in a near month contract position 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 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. Hypothetically, and assuming no other changes to either prevailing 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 interest earned on Treasuries, cash and/or cash equivalents), the value of the next month contract would rise as it approaches expiration and becomes the new near month contract. In this example, the value of the $50 investment would tend to rise faster than the spot price of crude oil, or fall slower. As a result, it would be possible in this hypothetical example for the price of spot crude oil to have risen to $60 after some period of time, while the value of the investment in the futures contract would have risen to $65, assuming backwardation is large enough or enough time has elapsed. Similarly, the spot price of crude oil could have fallen to $40 while the value of an investment in the futures contract could have fallen to only $45. Over time, if backwardation remained constant, the difference would continue to increase. In the event of a prolonged period of backwardation, and absent the impact of rising or falling crude oil prices, this could have a significant positive impact on USBO’s NAV and total return.

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. Hypothetically, and assuming no other changes to either prevailing 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 interest earned on cash), the value of the next month contract would fall as it approaches expiration and becomes the new near month contract. In this example, it would mean that the value of the $50 investment would tend to rise slower than the spot price of

58

crude oil, or fall faster. As a result, it would be possible in this hypothetical example for the spot price of crude oil to have risen to $60 after some period of time, while the value of the investment in the futures contract will have risen to only $55, assuming contango is large enough or enough time has elapsed. Similarly, the spot price of crude oil could have fallen to $45 while the value of an investment in the futures contract could have fallen to $40. Over time, if contango remained constant, the difference would continue to increase. In the event of a prolonged period of contango, and absent the impact of rising or falling crude oil prices, this could have a significant negative impact on USBO’s NAV and total return.

Historically, the oil futures markets have experienced periods of contango and backwardation, with backwardation being in place more often than contango. During the previous two years, including 2006 and the first half of 2007, these markets have experienced contango. However, starting early in the third quarter of 2007, the crude oil futures market moved into backwardation and remained in that condition for the rest of the year. The crude oil markets remained in backwardation for all of the first quarter of 2008. The chart below compares the price of the near month contract to the price of the second month contract over the last 10 years (1998-2007). When the price of the near month contract is higher than the price of the second month contract, the market would be described as being in backwardation. When the price of the near month contract is lower than the price of the second month contract, the market would be described as being in contango. Although the prices of the near month contract and the price of the second month contract do tend to move up or down together, it can be seen that at times the near month prices are clearly higher than the price of the second month contract (backwardation), and other times they are below the price of the second month contract (contango).

An alternative way to view the same data is to subtract from the dollar price of the near month contract the dollar price of the second month contract. If the resulting number is a positive number, then the near month price is higher than the price of the second month contract 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 price of the second month contract and the market could be described as being in contango. The chart below shows the results from subtracting from the near month price the price of the second month contract for the 10 year period between 1998 and 2008.

Periods of contango or backwardation do not meaningfully impact USBOs investment objective of having percentage changes in its per unit NAV track percentage changes in the price of the Benchmark Futures Contract since the impact of backwardation and contango tended to equally impact the percentage changes in price of both USBOs 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.

TABLE OF CONTENTS

## What Is the Flow of Units?

## What Are the Trading Policies of USBO?

### Liquidity

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

### Spot Commodities

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

### Leverage

While USBO expects its ratio of margin to total assets to generally range from 10% to 20%, the General Partner endeavors to have the value of USBO’s Treasuries, cash and cash equivalents, whether held by USBO or posted as margin or collateral, at all times approximate the aggregate market value of USBO’s obligations under its Futures Contracts and Other Crude Oil-Related Investments.

### Borrowings

Borrowings will not be used by USBO, unless USBO is required to borrow money in the event of physical delivery, USBO trades in cash commodities, or for short-term needs created by unexpected redemptions. USBO expects to have the value of its Treasuries, cash and cash equivalents, whether held by USBO or

61

TABLE OF CONTENTS

posted as margin or collateral, to at all times approximate the aggregate market value of its obligations under USBO’s Futures Contracts and Other Crude Oil-Related Investments. USBO does not plan to establish credit lines.

### 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 crude oil market. Consequently, USBO may purchase options on 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. 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 that the other party may not be able to perform its obligations under its contract.

Some crude oil-based derivatives transactions contain fairly generic terms and conditions and are available from a wide range of participants. Other crude oil-based derivatives have highly customized terms and conditions and are not as widely available. Many of these over-the-counter contracts are cash-settled forwards for the future delivery of crude oil- or petroleum-based fuels that have terms similar to the Futures Contracts. Others take the form of “swaps” in which the two parties exchange cash flows based on pre-determined formulas tied to the crude oil spot price, forward crude oil price, the Benchmark Futures Contract price, or other crude oil futures contract price. For example, USBO may enter into over-the-counter derivative contracts whose value will be tied to changes in the difference between the crude oil spot price, the Benchmark Futures Contract price, or some other futures contract price traded on New York Mercantile Exchange or ICE Futures Exchange and the price of other Futures Contracts that may be invested in by USBO.

To protect itself from the credit risk that arises in connection with such contracts, USBO will enter into agreements with each counterparty that provide for the netting of its overall exposure to its counterparty, such as the agreements published by the International Swaps and Derivatives Association, Inc. USBO will also require that the counterparty be highly rated and/or provide collateral or other credit support to address USBO’s exposure to the counterparty.

The creditworthiness of each potential counterparty will be assessed by the General Partner. The General Partner will assess or review, 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 of Directors. Furthermore, the General Partner on behalf of USBO will only enter into over-the-counter contracts with counterparties who are, or affiliates of, (a) banks regulated by a United States federal bank regulator, (b) broker-dealers regulated by the SEC, (c) insurance companies domiciled in the United States, and (d) producers, users or traders of energy, whether or not regulated by the CFTC. Any entity acting as a counterparty shall be regulated in either the United States or the United Kingdom unless otherwise approved by the General Partner’s Board of Directors after consultation with its legal counsel. Existing counterparties are also reviewed periodically by the General Partner.

USBO anticipates that the use of Other Crude Oil-Related Investments together with its investments in Futures Contracts will produce price and total return results that closely track the investment goals of USBO.

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. The effect of holding such combined positions is to adjust the sensitivity of USBO to changes in the price relationship between futures contracts which will expire sooner and those that will expire later. USBO would use such a spread if the General Partner felt that taking such long and short positions, when combined with the rest of its holdings, would more closely track the investment goals of USBO, or if the General Partner felt it would lead to an overall lower cost of trading to achieve a given level of economic exposure to movements in crude oil prices.

62

TABLE OF CONTENTS

USBO would enter into a straddle when it chooses to take an option position consisting of a long (or short) position in both a call option and put option. The economic effect of holding certain combinations of put options and call options can be very similar to that of owning the underlying futures contracts. USBO would make use of such a straddle approach if, in the opinion of the General Partner, the resulting combination would more closely track the investment goals of USBO or if it would lead to an overall lower cost of trading to achieve a given level of economic exposure to movements in crude oil prices.

### Pyramiding

USBO 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.

## Who Are the Service Providers?

Brown Brothers Harriman & Co. is anticipated to be the registrar and transfer agent for the units. Brown Brothers Harriman & Co. is also anticipated to be the Custodian for USBO. In this capacity, Brown Brothers Harriman & Co. will hold USBO’s Treasuries, cash and cash equivalents pursuant to a custodial agreement. In addition, Brown Brothers Harriman & Co. will perform certain administrative and accounting services for USBO and will prepare certain SEC and CFTC reports on behalf of USBO. The General Partner will pay Brown Brothers Harriman & Co.’s fees.

USBO also plans to employ ALPS Distributors, Inc. as the Marketing Agent, which is further discussed under “What is the Plan of Distribution?” The General Partner will pay the Marketing Agent’s fees.

USBO and the futures commission merchant, UBS Securities LLC (“UBS Securities”), will enter into an Institutional Futures Client Account Agreement. This Agreement requires UBS Securities to provide services to USBO in connection with the purchase and sale of Crude Oil Interests that may be purchased or sold by or through UBS Securities for USBO’s account. USBO will pay the futures commission merchant fees.

UBS Securities is not affiliated with us or our General Partner. Therefore, we do not believe that we have any conflicts of interest with them or their trading principals arising from their acting as our futures commission merchant.

UBS Securities’ principal business address is 677 Washington Blvd, Stamford, CT 06901. UBS Securities is a futures clearing broker for USBO. UBS Securities is registered in the US with FINRA as a Broker-Dealer and with the CFTC as a Futures Commission Merchant. UBS Securities is a member of various US futures and securities exchanges.

UBS Securities is the defendant in two purported securities class actions pending in District Court of the Northern District of Alabama, brought by holders of stocks and bonds of HealthSouth, captioned In re HealthSouth Corporation Stockholder, No. CV-03-BE-1501-S and In re HealthSouth Corporation Bondholder Litigation, No. CV-03-BE-1502-S. Both complaints assert liability under the Securities Act of 1934.

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 LLC, captioned In The Matter of UBS Securities, LLC, Docket No. E-2007-0049, which alleges, in sum and substance, that UBS Securities has been violating 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. The Complaint seeks a cease and desist order from conduct that violates the Act and regulations, to censure UBS Securities, to require UBS Securities to pay an administrative fine of an unspecified amount, and to find as fact the allegations of the Complaint.

On June 26, 2008, the Massachusetts Securities Division filed an administrative complaint and notice of adjudicatory proceeding against UBS Securities and UBS Financial Services, Inc. (“UBS Financial”), captioned In the Matter of UBS Securities, LLC and UBS Financial Services, Inc., Docket No. 2008-0045, which alleged that UBS Securities and UBS Financial violated the Act in connection with the marketing and sale of auction rate securities.

On July 22, 2008, the Texas State Securities board filed an administrative proceeding against UBS Securities and UBS Financial captioned the Matter of the Dealer Registrations of UBS Financial Services, Inc. and UBS Securities LLC, SOAH Docket No. 312-08-3918, SSB Docket No. 08-IC04, alleging violations of the anti-fraud provision of the Texas Securities Act in connection with the marketing and sale of auction rate securities.

On July 24, 2008 the New York Attorney General (“NYAG”) filed a complaint in Supreme Court of the State of New York against UBS Securities and UBS Financial captioned State of New York v. UBS Securities LLC and UBS Financial Services, Inc., No. 650262/2008, in connection with UBS’s marketing and sale of auction rate securities. The complaint alleges violations of the anti-fraud provisions of New York state statutes and seeks a judgment ordering that the firm buy back auction rate securities from investors at par, disgorgement, restitution and other remedies.

On August 8, 2008, UBS Securities and UBS Financial reached agreements in principle 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 August 20, 2008, the Texas proceeding was dismissed and withdrawn. 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.

On August 14, 2008 the New Hampshire Bureau of Securities Regulation filed an administrative action against UBS Securities relating to a student loan issuer, the New Hampshire Higher Education Loan Corp.

## 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 will keep a record of all limited partners and holders of the units in certificated form in the registry (“Register”). The General Partner will recognize transfers of units in certificated form only if done in accordance with the LP Agreement. The beneficial interests in such units will be held in book-entry form through participants and/or accountholders in DTC.

Book-Entry. 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 Administrator with DTC and registered in the name of Cede & Co., as nominee for DTC. The global certificates will 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 banks, brokers, dealers, trust companies and others 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 will be credited to DTC Participants’ securities accounts following confirmation of receipt of payment.

DTC. DTC 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.

65

TABLE OF CONTENTS

## 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 will be 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 definitive security in respect of such interest.

DTC has advised us 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 limited partner interests 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 offered by this prospectus must execute a transfer application and certification. The obligation to provide the form of transfer application will be 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 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, our units will be securities and will be transferable according to the laws governing transfers of securities.

66

TABLE OF CONTENTS

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, our LP Agreement;

| • | represent that such transferee has the capacity and authority to enter into our LP Agreement;

| • | grant powers of attorney to our General Partner and any liquidator of us; and

| • | make the consents and waivers contained in our LP Agreement.

An assignee will become a limited partner in respect of the transferred units upon the consent of our General Partner and the recordation of the name of the assignee on our books and records. Such consent may be withheld in the sole discretion of our 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 our books, we 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 will buy and sell units of USBO in secondary market transactions through brokers. Units will trade on the NYSE Arca under the ticker symbol “BNO”. Units will be bought and sold throughout the trading day like other publicly traded securities. When buying or selling units through a broker, most investors will incur customary brokerage commissions and charges. Investors are encouraged to review the terms of their brokerage account for details on applicable charges.

67

TABLE OF CONTENTS

### Marketing Agent and Authorized Purchasers

The offering of USBO’s units is a best efforts offering. USBO will continuously offer Creation Baskets consisting of 100,000 units through the Marketing Agent, to Authorized Purchasers. [TBD] is expected to be the initial Authorized Purchaser. It is expected that on the effective date, the initial Authorized Purchaser will, subject to conditions, purchase one or more initial Creation Baskets of 100,000 units at a price per unit equal to $50. It is expected that the proceeds from that purchase will be invested on that day and that USBO’s initial per unit net asset value will be established as of 4:00 p.m. New York City time that day. Authorized Purchasers will pay a $1,000 fee for each order to create one or more Creation Baskets. The Marketing Agent will receive, for its services as marketing agent to USBO, a marketing fee of 0.06% on assets up to the first $3 billion and 0.04% on 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 of units exceed ten percent (10%) of the gross proceeds of this offering.

The initial Authorized Purchaser proposes to offer to the public these 100,000 units 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 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 and the offering prices 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 offered by the initial Authorized Purchaser at different times may have different offering prices. The initial Authorized Purchaser will not receive from USBO, the General Partner or any of their affiliates, any fee or other compensation in connection with the sale of the units. USBO will not bear any expenses in connection with the offering or sales of the initial Creation Basket of units.

The offering of baskets is being made in compliance with Conduct Rule 2810 of FINRA. Accordingly, the initial Authorized Purchaser will not make any sales to any account over which it has 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, the 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.

As of the date of this prospectus, [TBD] is the only expected Authorized Purchaser. 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, including the initial Authorized Purchaser, 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. For example, the initial Authorized Purchaser will be a statutory underwriter with respect to its initial purchase of Creation Baskets.

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

68

TABLE OF CONTENTS

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

Brown Brothers Harriman & Co., Inc, the Administrator, will calculate the NAV of USBO once each NYSE Arca trading day. The NAV for a particular trading day will be 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 will use the ICE Futures Exchange settlement price (a weighted average price of trades during a three minute settlement period from 2:27 p.m. New York time) for the contracts traded on the ICE Futures Exchange, but will calculate or determine 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 in accordance with the current Administrative Agency Agreement among Brown Brothers Harriman & Co., USBO and the General Partner.

In addition, in order to provide updated information relating to USBO for use by investors and market professionals, the NYSE Arca will calculate and disseminate throughout the core trading session on each trading day an updated indicative fund value. The indicative fund value will be 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 these Futures Contract months will be 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 will not be 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 NAV is calculated only once at the end of each trading day based upon the relevant end of day values of USBO’s investments.

The NYSE Arca will disseminate the indicative fund value through the facilities of CTA/CQ High Speed Lines. In addition, the indicative fund value will be published on the NYSE Arca’s website and will be 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 will be able through out 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

69

TABLE OF CONTENTS

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 will be 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 will not be 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 for Brent crude oil traded on the ICE Futures Exchange.

## Creation and Redemption of Units

USBO will create and redeem units from time to time, but only in one or more Creation Baskets or Redemption Baskets. The creation and redemption of baskets will only be 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 will be 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 will be 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 as 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 creations 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 will pay a transaction fee of $1,000 to USBO for each order they place to create or redeem one or more baskets. Authorized Purchasers who make deposits with USBO in exchange for baskets will 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 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 have the facility to participate directly in the physical crude oil market and the crude oil futures market. In some cases, an Authorized Purchaser or its affiliates may from time to time acquire crude oil or sell crude oil 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 impact the price of crude oil, Futures Contracts, or the price of the units.

Each Authorized Purchaser will be registered as a broker-dealer under the Exchange Act and is a member in good standing with FINRA, or will be exempt from being or otherwise will not be required to be licensed as a broker-dealer or a member of FINRA, and will be 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 will have 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 1933 Act, and to contribute to the payments the Authorized Purchasers may be required to make in respect of those liabilities.

TABLE OF CONTENTS

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, each of which 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 Exchange or the New York Stock Exchange 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; except in the case of the initial Authorized Purchaser’s or any other Authorized Purchaser’s 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 a.m. New York time on the day agreed to by the General Partner and the initial Authorized Purchaser. The day on which the Marketing Agent receives a valid purchase order is the purchase order date.

By placing a purchase order, an Authorized Purchaser agrees to deposit Treasuries with USBO, or a combination of Treasuries and cash, as described below. Prior to 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 USBO, 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 type 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”) will be an 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 date the order to purchase 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 date the order is received. 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 will be 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 will direct 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 shall be borne solely by the Authorized Purchaser.

71

TABLE OF CONTENTS

Because orders to purchase baskets must be placed by 12:00 p.m., New York time (except in the case of the initial Authorized Purchaser’s or any other Authorized Purchaser’s 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 a.m. New York time on the day agreed to by the General Partner and the initial Authorized Purchaser), 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.

### 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 Arca, 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. Authorized Purchasers may not withdraw a redemption request.

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. Prior to

72

TABLE OF CONTENTS

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.

### Determination of Redemption Distribution

The redemption distribution from USBO will consist 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 such requirements as of 4:00 p.m. New York time on the redemption order date.

### 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 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. 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., one basket) or less, unless the General Partner has reason to believe that the placer of the redemption order does in fact possess all the outstanding units and can deliver them.

73

TABLE OF CONTENTS

### 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 $1,000 per order to create or 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 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.

### 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 or interest thereon.

### Secondary Market Transactions

As noted, USBO will create and redeem units from time to time, but only in one or more Creation Baskets or Redemption Baskets. The creation and redemption of baskets will only be 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.

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 are expected to 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.

74

TABLE OF CONTENTS

## Use of Proceeds

The General Partner will initially apply substantially all of USBO’s assets toward taking positions in Futures Contracts and Other Crude Oil-Related Investments and investing in Treasuries, cash and/or cash equivalents. The General Partner has sole authority to determine the percentage of assets that will be:

| • | 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.

The General Partner expects to deposit a majority of USBO’s net assets with the Custodian or other custodian. When USBO sells or purchases a Futures Contract and certain exchange traded Other Crude Oil-Related Investments, USBO is required to deposit with the 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 Interests at maturity. This deposit is known as “margin.” USBO will invest the remainder of its assets equal to the difference between the margin deposited and the market value of the position in the Futures Contract in Treasuries, cash and/or cash equivalents.

The General Partner expects that all entities that will hold or trade USBO’s assets will be based in the United States and will be subject to United States regulations.

The General Partner believes that 10% to 20% of USBO’s assets will normally be committed as margin for its positions in Futures Contracts. However, from time to time, the percentage of assets committed as margin may be substantially more, or less, than such range. The General Partner intends to invest the balance of USBO’s assets not invested in Crude Oil Interests or held in margin as reserves to be available for changes in margin. All interest income will be used for USBO’s benefit.

The futures commission merchant, a government agency or a commodity exchange could increase margins 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 taken.

USBO’s assets will be held in segregated accounts pursuant to the Commodity Exchange Act and CFTC regulations.

## Management’s Discussion and Analysis of Financial Condition and Results of Operations

### Critical Accounting Policies

Preparation of the financial statements and related disclosures in compliance with accounting principles generally accepted in the United States of America requires the application of appropriate accounting rules and guidance, as well as the use of estimates. USBO’s application of these policies involves judgments and actual results may differ from the estimates used.

The General Partner has evaluated the nature and types of estimates that it will make in preparing USBO’s financial statements and related disclosures once USBO commences trading operations and has determined that the valuation of its investments which are not traded on a U.S. or internationally recognized futures exchange (such as forward contracts and over-the-counter contracts) involves a critical accounting policy. While not currently applicable given the fact that USBO is not currently involved in trading activities, the values which will be used by USBO for its forward contracts will be provided by its commodity broker who will use market prices when available, while over-the-counter contracts will be valued based on the present value of estimated future cash flows that would be received from or paid to a third party in settlement of these derivative contracts prior to their delivery date and will be valued on a daily basis.

### Liquidity and Capital Resources

USBO does not anticipate making use of borrowings or other lines of credit to meet its obligations. It is anticipated that USBO will meet its liquidity needs in the normal course of business from the proceeds of the sale of its investments or from the cash, cash equivalents and/or the Treasuries that it intends to hold at all times. USBO’s liquidity needs include: redeeming units, providing margin deposits for its existing Futures

75

TABLE OF CONTENTS

Contracts or the purchase of additional Futures Contracts, posting collateral for its over-the-counter contracts and payment of its expenses, summarized below under “Contractual Obligations.”

USBO will generate cash primarily from (i) the sale of Creation Baskets and (ii) interest earned on cash, cash equivalents and its investments in Treasuries. USBO has not begun trading activities. Once USBO begins trading activities, it is anticipated that all of its net assets will be allocated to trading in Crude Oil Interests. Most of USBO’s assets will be held in Treasuries, cash and/or cash equivalents that could or will be used as margin for USBO’s trading in Crude Oil Interests. The percentage that Treasuries will bear to the total net assets will vary from period to period as the market values of the Crude Oil Interests change. The balance of the net assets will be held in USBO’s Futures Contracts and Other Crude Oil-Related Investments trading account. Interest earned on USBO’s interest bearing-funds will be paid to USBO.

USBO’s investment in Crude Oil Interests will be subject to periods of illiquidity because of market conditions, regulatory considerations and other reasons. For example, most commodity exchanges limit the fluctuations in Futures Contracts prices during a single day by regulations referred to as “daily limits.” During a single day, no trades may be executed at prices beyond the daily limit. Once the price of a Futures Contract has increased or decreased by an amount equal to the daily limit, positions in the contracts can neither be taken nor liquidated unless the traders are willing to effect trades at or within the limit. Such market conditions could prevent USBO from promptly liquidating its positions in Futures Contracts.

To date, all of USBO’s expenses have been funded by the General Partner. If the General Partner and USBO are unsuccessful in raising sufficient funds to cover its expenses or in locating any other source of funding, USBO will terminate and investors may lose all or part of their investment.

### Market Risk

Trading in Futures Contracts and Other Crude Oil-Related Investments such as forwards will involve USBO entering into contractual commitments to purchase or sell crude oil at a specified date in the future. The gross or face amount of the contracts will significantly exceed USBO’s future cash requirements since USBO intends to close out its open positions prior to settlement. As a result, USBO should only be subject to the risk of loss arising from the change in value of the contracts. USBO considers the “fair value” of its derivative instruments to be the unrealized gain or loss on the contracts. The market risk associated with USBO’s commitments to purchase crude oil will be limited to the aggregate face amount of the contracts held. However, should USBO enter into a contractual commitment to sell crude oil, it would be required to make delivery of the crude oil at the contract price, repurchase the contract at prevailing prices or settle in cash. Since there are no limits on the future price of crude oil, the market risk to USBO could be unlimited.

USBO’s exposure to market risk will depend on a number of factors including the markets for crude oil, the volatility of interest rates and foreign exchange rates, the liquidity of the Futures Contracts and Other Crude Oil-Related Investments markets and the relationships among the contracts held by USBO. The limited experience that USBO has had in utilizing its model to trade in Crude Oil Interests in a manner intended to track the changes in the spot price of crude oil, as well as drastic market occurrences, could ultimately lead to the loss of all or substantially all of an investor’s capital.

### Credit Risk

When USBO enters into Futures Contracts and Other Crude Oil-Related Investments, it will be exposed to the credit risk that its counterparty will not be able to meet its obligations. The counterparty for the Futures Contracts traded on the ICE Futures Exchange and on most other foreign and domestic futures exchanges is the clearinghouse associated with the particular exchange. In general, clearinghouses are backed by their members who may be required to share in the financial burden resulting from the nonperformance of one of their members that should significantly reduce credit risk. Some foreign exchanges are not backed by their clearinghouse members but may be backed by a consortium of banks or other financial institutions. There can be no assurance that any counterparty, clearing house, or their financial backers will satisfy their obligations to USBO.

The General Partner will attempt to manage the credit risk of USBO by following various trading limitations and policies. In particular, USBO intends to post margin and/or hold liquid assets that will be approximately equal to the face amount of its obligations to counterparties under the Futures Contracts and

76

TABLE OF CONTENTS

Other Crude Oil-Related Investments it holds. The General Partner will implement procedures that will include, but will not be limited to, executing and clearing trades only with creditworthy parties and/or requiring the posting of collateral or margin by such parties for the benefit of USBO to limit its credit exposure.

USBO’s commodity broker, or any other broker that may be retained by USBO in the future, when acting as USBO’s futures commission merchant in accepting orders to purchase or sell Futures Contracts on United States exchanges, will be required by CFTC regulations to separately account for and segregate as belonging to USBO, all assets of USBO relating to domestic Futures Contracts trading. These commodity brokers are not allowed to commingle USBO’s assets with their other assets. In addition, the CFTC requires commodity brokers to hold in a secure account the USBO assets related to foreign Futures Contract trading.

### Off Balance Sheet Financing

As of the date of this prospectus, USBO has no loan guarantee, credit support or other off-balance sheet arrangements of any kind other than agreements entered into in the normal course of business, which may include indemnification provisions relating to certain risks service providers undertake in performing services which are in the best interests of USBO. While USBO’s exposure under these indemnification provisions cannot be estimated, they are not expected to have a material impact on USBO’s financial position.

### Redemption Basket Obligation

Other than as necessary to meet its investment objective and pay its contractual obligations described below, USBO will require liquidity to redeem Redemption Baskets. USBO intends to satisfy this obligation through the transfer of its Treasuries and/or cash in an amount proportionate to the number of units being redeemed, as described above under “Determination of Redemption Distribution.”

### Contractual Obligations

USBO’s primary contractual obligations will be with the General Partner. In return for its services, the General Partner will be entitled to a management fee calculated as a fixed percentage of USBO’s NAV, currently 0.75% of its average net assets.

The General Partner has agreed to pay the start-up costs associated with the formation of USBO, primarily its legal, accounting and other costs in connection with its contracts with service providers and its registration with the SEC and other regulatory filings in connection with the initial public offering of the units, and the registration fees paid to the SEC, FINRA and the NYSE Arca in connection with such offering. The General Partner has agreed to pay the fees of the Custodian and transfer agent, Brown Brothers Harriman & Co., as well as Brown Brothers Harriman & Co.’s fees for performing administrative services, including in connection with USBO’s preparation of its financial statements and its SEC and CFTC reports. The General Partner will also pay the fees of USBO’s accountants in connection with its SEC and CFTC reporting, as well as those of its Marketing Agent.

In addition to the General Partner’s management fee, USBO pays its brokerage fees (including fees to the futures commission merchant), over-the-counter dealer spreads, any licensing fees for the use of intellectual property, registration and, subsequent to the initial offering, the fees paid to the SEC, FINRA, or other regulatory agency in connection with the offer and sale of the units, tax accounting and reporting fees, as well as the legal, printing, accounting, and other expenses associated therewith, and extraordinary expenses. The latter are expenses not in the ordinary course of its business, including the indemnification of any person against liabilities and obligations to the extent permitted by law and under the LP Agreement, the bringing or defending of actions in law or in equity or otherwise conducting litigation and incurring legal expenses and the settlement of claims and litigation. Commission payments to the futures commission merchant are on a contract-by-contract, or round turn, basis.

The parties cannot anticipate the amount of payments that will be required under these arrangements for future periods as USBO’s net asset values and trading levels to meet its investment objectives will not be known until a future date. These agreements are effective for a specific term agreed upon by the parties with an option to renew, or, in some cases, are in effect for the duration of USBO’s existence. Either party may terminate these agreements earlier for certain reasons listed in the agreements.

The following paragraphs are a summary of certain provisions of our LP Agreement. It is expected that the initial limited partner of USBO will be [TBD]. The following discussion is qualified in its entirety by reference to our LP Agreement.

### 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 Our 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,

78

TABLE OF CONTENTS

|  | 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).

### 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.

## Fees of USBO

### Management Fees

USBO is contractually obligated to pay the General Partner a management fee based on 0.75% per annum on average net assets. Fees are calculated on a daily basis (accrued at 1/365 of the applicable percentage of NAV on that day) and paid on a monthly basis. NAV is calculated by taking the current market value of USBO’s total assets and subtracting any liabilities.

### Brokerage Fees

Brokerage fees |  | Approximately 0.14%

Fees are calculated on a daily basis (based on a percentage of the value of the transaction) and paid on a monthly basis. These fees, including the brokerage fee for Futures Contracts based upon the futures commission merchant’s fees shown below, are estimated on an annualized percentage basis.

### Futures Commission Merchant Fee

Futures Commission Merchant fee |  | Approximately $4.00 per buy or sell

Fees are calculated on a daily basis for each buy or sell and paid on a monthly basis. These are the basis for and not in addition to the brokerage fee for Futures Contracts included in the brokerage fees shown above.

## 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.

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 will not be 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 invest 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 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 this fund, or the sale or distribution of USBO’s assets.

TABLE OF CONTENTS

The General Partner serves as the general partner to USBO and the Related Public Funds, as well as US12NG, which has 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, USBO purchased gasoline futures contracts on NYMEX, this decision could impact UGA’s ability to purchase additional gasoline futures contracts if the number of contracts held by funds managed by the General Partner reached the maximum allowed by NYMEX. Similar situations could adversely affect the ability of any fund to track its Benchmark Futures Contract.

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 employed Sutherland Asbill & Brennan LLP to prepare 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 Responsibility 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.

81

TABLE OF CONTENTS

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 Commodity Exchange Act for violations of the Commodity Exchange Act 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.

82

TABLE OF CONTENTS

## 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. If any indemnification of the General Partner arises out of an alleged violation of such laws, it is subject to certain legal conditions.

Those conditions require that no indemnification 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: there has been a successful adjudication on the merits of each count involving alleged securities law violations as to the General Partner or other particular indemnitee, or such claim has been dismissed with prejudice on the merits by a court of competent jurisdiction as to the General Partner or other particular indemnitee, or a court of competent jurisdiction approves a settlement of the claims against the General Partner or other agent of USBO and finds that indemnification of the settlement and related costs should be made, provided, 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.

### Provisions of the Securities Act of 1933 and NASAA Guidelines

Insofar as indemnification for liabilities arising under the 1933 Act 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 1933 Act 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 1320 Harbor Bay Parkway, Suite 145, Alameda, California 94502 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 set forth in the financial statements in this prospectus 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

TABLE OF CONTENTS

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 and the CFTC, 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

### As provided in the LP Agreement, the following reports will be provided to limited partners:

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,

| (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 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 will initially be the calendar year. The General Partner may select an alternate fiscal year.

84

TABLE OF CONTENTS

## 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.

## 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.

### Legal Opinion

Sutherland Asbill & Brennan LLP is counsel to advise USBO and the General Partner with respect to the units being offered hereby and has passed upon the validity of the units being issued hereunder. Sutherland Asbill & Brennan LLP has also provided the General Partner with its opinion with respect to federal income tax matters addressed herein.

## Experts

## Privacy Policy

USBO and the General Partner collect certain nonpublic personal information about investors from the information provided by them in certain documents, as well as in the course of processing transaction requests. None of this information is disclosed except as necessary in the course of processing creations and redemptions and otherwise administering USBO — and then only subject to customary undertakings of confidentiality. USBO and the General Partner do not disclose nonpublic personal information about investors to anyone, except as required by law or as described in its Privacy Policy. In general, USBO and the General Partner restrict access to the nonpublic personal information they collect from investors to those of its and its affiliates’ employees and service providers who need access to this information to provide products and services to investors. USBO and the General Partner each maintain physical, electronic and procedural controls to safeguard this information. These standards are reasonably designed to (1) ensure the security and confidentiality of investors’ records and information, (2) protect against any anticipated threats or hazards to the security or integrity of investors’ records and information, and (3) protect against unauthorized access to or use of investors’ records or information that could result in substantial harm or inconvenience to any investor. A copy of the current Privacy Policy can be provided upon request and is provided to investors annually.

## 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 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.

85

TABLE OF CONTENTS

Persons considering the purchase, ownership or disposition of units should consult their own tax advisors concerning the United States 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 United States 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 United States 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 Sutherland Asbill & Brennan 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, Sutherland Asbill & Brennan 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 Sutherland Asbill & Brennan 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.

### Tax Status of USBO

USBO is organized and will be operated 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 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 Sutherland Asbill & Brennan 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, Sutherland Asbill & Brennan LLP is of the opinion that USBO will be classified as a partnership for federal income tax purposes and that it will not be 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 federal income tax purposes and would pay 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

86

TABLE OF CONTENTS

their returns. In addition, distributions to unitholders would be treated as dividends 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 will be classified as a partnership for federal income tax purposes and that it will not be taxable as a corporation.

### U.S. Unitholders

#### Tax Consequences of Ownership of Units

Taxation of USBO’s Income. No U.S. federal income tax will be paid by USBO on its income. Instead, USBO will file annual information returns, and each U.S. unitholder will be 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 will 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.

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.

In general, USBO will apply a monthly closing-of-the-books convention in determining allocations of economic profit or loss to unitholders. Income, gain, loss and deduction will be 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 will be 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 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 intends to make the election permitted by section 754 of the Code, which election will be irrevocable without the consent of the Service. The effect of this election will be that when a secondary market sale of our units occur, we will 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 will apply 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 will be consistent with the intent of the partnership provisions of the Code, and that the resulting allocations will have substantial economic effect or otherwise will be respected as being in accordance with unitholders’ interests in USBO for federal income tax purposes. However, the Code and Treasury Regulations do not expressly permit adoption of these assumptions and

87

TABLE OF CONTENTS

conventions, and Sutherland Asbill & Brennan 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 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 federal income tax purposes, USBO generally will be 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, will be 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 will be 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.

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.

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

88

TABLE OF CONTENTS

Partner and other expenses we incur will 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 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 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 of 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 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 Fund Distributions. If USBO makes non-liquidating distributions to unitholders, such distributions generally will not be taxable to the unitholders for 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

89

TABLE OF CONTENTS

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 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-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 intend to report tax information to the beneficial owners of units. Unitholders who have become additional limited partners will be treated as partners for 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 federal income tax purposes. On the basis of such ruling, except as otherwise provided herein, we intend to treat the following persons as partners for 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.

90

TABLE OF CONTENTS

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 $50 per failure, up to a maximum of $100,000 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 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 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” and represent the partnership purposes of these proceedings. The LP Agreement appoints the General Partner as the tax matters partner of USBO.

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 United States federal income tax return. In addition, certain “material advisers” must maintain a list of persons participating in such transactions and furnish the list to the IRS upon written request. 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 (1) if a unitholder incurs a loss in excess a specified threshold from a sale or redemption of its units, (2) if USBO engages in transactions producing differences between its taxable income and its income for financial reporting purposes, or (3) 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 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 and 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

91

TABLE OF CONTENTS

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 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 Service. An exempt organization unitholder will be required to make payments of estimated federal income tax with respect to its UBTI.

Regulated Investment Companies. Under recently enacted legislation, 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 and 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.

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 will not result in USBO being engaged in a trade or business within in 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. 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

92

TABLE OF CONTENTS

refund of any withholding in excess of such unitholder’s actual U.S. federal income tax liability. Any amount withheld by USBO will be treated as a distribution to the non-U.S. unitholder.

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. Amounts withheld on behalf of a non-U.S. unitholder will be treated as being distributed to such unitholder.

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.

USBO expects that most of its interest income will qualify 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.”

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”) at a rate of 28 percent from all taxable distributions payable to: (1) any unitholder who fails to furnish 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 has failed to properly report certain interest and dividend income to the IRS and to respond to notices to that effect. Backup withholding is not an additional tax and may be returned or credited against a taxpayer’s regular federal income tax liability if appropriate information is provided to the IRS.

## Other Tax Considerations

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

93

responsibility to file the appropriate U.S. federal, state, local, and foreign tax returns. Sutherland Asbill & Brennan 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.

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

94

TABLE OF CONTENTS

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 will be satisfied with respect to the units. The General Partner believes that the units should therefore constitute publicly-offered securities, and the underlying assets of USBO should not be 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.

95

TABLE OF CONTENTS

### 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.

NOTES TO STATEMENT OF FINANCIAL CONDITION

## Note 1 — Organization and Business

United States Brent Oil Fund, LP (the “Fund” or “USBO”), was organized as a limited partnership under the laws of the state of Delaware on September 2, 2009. The Fund is a commodity pool that intends to issue units that may be purchased and sold on the NYSE Arca. The Fund will continue in perpetuity, unless terminated sooner upon the occurrence of one or more events as described in its Amended and Restated Agreement of Limited Partnership (the “Limited Partnership Agreement”). The net assets of USBO will consist primarily of positions 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 or other U.S. and foreign exchanges (collectively, “Futures Contracts”). USBO may also take positions in other crude oil-related investments such as cash-settled options on Futures Contracts, forward contracts for crude oil, 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”). The investment objective of USBO is to have the daily changes in percentage terms of the units’ net asset value (“NAV”) reflect the daily changes in percentage terms of the spot price of Brent crude oil as measured by the 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 “Benchmark Futures Contract”). United States Commodity Funds LLC, formerly known as Victoria Bay Asset Management, LLC, is the general partner of the Fund (the “General Partner”) and is also responsible for the management of the Fund. For the periods ended September 2, 2009 and September 30, 2009, the Fund’s organizational expenses in the amount of $0.00 and $273,350, respectively, have been funded by the General Partner. The Fund does not have any obligation or intention to reimburse such payments. The General Partner is a member of the National Futures Association (“NFA”) and is registered as a commodity pool operator with the Commodity Futures Trading Commission effective December 1, 2005. The Fund has a fiscal year ending on December 31.

The September 30, 2009 statement of financial condition is unaudited. In the opinion of management, all adjustments, consisting of normal recurring entries have been made in the accompanying financial statements.

The Fund will issue limited partnership interests (“Units”) to authorized purchasers by offering creation baskets consisting of 100,000 Units (“Creation Baskets”) through a marketing agent. The purchase price for a Creation Basket will be based upon the net asset value of a Fund Unit determined as of 4:00 p.m. New York Time on the day the order to create the basket is properly received. In addition, authorized purchasers will pay the Fund a $1,000 fee for the creation of each Creation Basket. Units may be purchased or sold on a nationally recognized securities exchange in smaller increments than a Creation Basket. Units purchased or sold on a nationally recognized securities exchange will not be made at the net asset value of the Fund but rather at market prices quoted on the stock exchange.

United States Commodity Funds LLC, the General Partner, is also the general partner of (1) United States Oil Fund, LP (“USOF”), which listed its Units on the American Stock Exchange under the ticker symbol “USO” on April 10, 2006; (2) United States Natural Gas Fund, LP (“USNG”), which listed its Units on the American Stock Exchange under the ticker symbol “UNG” on April 18, 2007, (3) United States 12 Month Oil Fund, LP (“US12OF”), which listed its Units on the American Stock Exchange under the ticker symbol “USL” on December 6, 2007, United States Gasoline Fund, LP (“USG”), which listed its Units on the American Stock Exchange under the ticker symbol “UGA” on February 26, 2008, and United States Heating Oil Fund, LP (“USHO”), which listed its Units on the American Stock Exchange under the ticker symbol “UHN” on April 9, 2008 (USOF, USNG, US12OF, USG and USHO, collectively, the “Related Funds”). The Units of the Related Funds began trading on NYSE Arca or in connection with NYSE Euronext’s acquisition of the American Stock Exchange. The General Partner is also the general partner of two other funds that have not commenced operations, United States Short Oil Fund, LP (“USSO”) and United States 12 Month Natural Gas Fund, LP (“US12NG”).

NOTES TO STATEMENT OF FINANCIAL CONDITION

## Note 1 — Organization and Business – (continued)

The Fund has filed a registration statement on Form S-1 with the Securities and Exchange Commission (“SEC”). The following summary of significant accounting policies will be followed by the Fund once operations commence.

## Note 2 — Summary of Significant Accounting Policies

### Revenue Recognition

Commodity futures contracts, forward contracts, physical commodities, and related options will be recorded on the trade date. All such transactions will be recorded on the identified cost basis and marked to market daily. Unrealized gains or losses on open contracts will be reflected in the statement of financial condition and the difference between original contract amount and market value (as determined by exchange settlement prices for futures contracts and related options and cash dealer prices at a predetermined time for forward contracts, physical commodities, and their related options) as of the last business day of the year or as of the last date of the financial statements. Changes in the unrealized gains or losses between periods will be reflected in the statement of operations. The Fund will earn interest on its assets on deposit at the clearing broker. In addition, the Fund will earn interest on funds held with its custodian at prevailing market rates earned on such investments.

### Brokerage Commissions

Brokerage commissions on all open commodity futures contracts will be accrued on a full-turn basis.

### General Partner Management Fee

Under the Limited Partnership Agreement, the General Partner is responsible for investing the assets of the Fund in accordance with the objectives and policies of the Fund. In addition, the General Partner will arrange for one or more third parties to provide administrative, custody, accounting, transfer agency and other necessary services to the Fund. For these services, the Fund is contractually obligated to pay a monthly management fee to the General Partner, based on average daily net assets, at a rate equal to 0.75% per annum on average net assets. The Fund will pay for all brokerage fees, taxes and other expenses, including licensing fees for the use of intellectual property, registration or other fees paid to the SEC, the Financial Industry Regulatory Authority (“FINRA”), formerly the National Association of Securities Dealers, or any other regulatory agency in connection with the offer and sale of subsequent Units after the initial registration and all legal, accounting, printing and other expenses associated therewith. The Fund also pays (1) the fees and expenses, including directors and officers’ liability insurance, of the independent directors and (2) the fees and expenses associated with the partnership’s tax accounting and reporting requirements with the exception of certain initial implementation services fees and base services fees which will be paid by the General Partner.

### Offering Costs

Offering costs incurred in connection with the registration of additional units after the initial registration of Units will be borne by the Fund. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated therewith. These costs will be accounted for as a deferred charge and thereafter amortized to expense over twelve months on a straight line basis or a shorter period if warranted.

### Income Taxes

The Fund is not taxed on its income; instead, the individual investors’ respective share of the Fund’s taxable income will be reported on the individual investors’ income tax returns.

F-5

# UNITED STATES BRENT OIL FUND, LP
NOTES TO STATEMENT OF FINANCIAL CONDITION

## Note 2 — Summary of Significant Accounting Policies – (continued)

### Additions and Redemptions

Authorized purchasers may purchase Creation Baskets consisting of 100,000 Units from the Fund as of the beginning of each business day based upon the prior day’s net asset value. Authorized purchasers may redeem Units from the Fund only in blocks of 100,000 Units called “Redemption Baskets.” The amount of the redemption proceeds for a Redemption Basket will be equal to the net asset value of the Units in the Redemption Basket determined as of 4:00 p.m. New York Time on the day the order to redeem the basket is properly received.

The Fund receives or pays the proceeds from Units sold or redeemed within three business days after the trade date of the purchase or redemption. The amounts due from authorized purchasers are reflected in the Fund’s statement of financial condition as receivable for Units sold and amounts payable to authorized purchasers upon redemption is reflected as payable for Units redeemed.

### Partnership Capital and Allocation of Partnership Income and Losses

Profit or loss shall be allocated among the partners of the Fund in proportion to the number of Units each partner holds as of the close of each month. The General Partner may revise, alter or otherwise modify this method of allocation as described in the Limited Partnership Agreement.

### Calculation of Net Asset Value

The Fund will calculate its net asset value on each trading day by taking the current market value of its total assets, subtracting any liabilities and dividing the amount by the total number of Units issued and outstanding. The Fund will use the New York Mercantile Exchange closing price on that day for contracts held on the New York Mercantile Exchange.

### Cash Equivalents

Cash equivalents will include highly liquid investments with original maturities of three months or less.

### Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statement, and the reported amounts of the revenue and expenses during the reporting period. Actual results could differ from those estimates.

## Note 3 — Contracts and Agreements

The Fund has entered into a marketing agent agreement with ALPS Distributors Inc., a Colorado corporation (“ALPS”), whereby ALPS will provide certain marketing services. These fees will be paid by the General Partner and not charged to the Fund.

The following expenses will also be borne by the General Partner: cost of placing advertisements in various periodicals; web construction and development; and the printing and production of various marketing materials.

The Fund will enter into a custodian agreement with Brown Brothers Harriman & Co. (“Brown Brothers”), whereby Brown Brothers will hold investments on behalf of the Fund. The General Partner of the Fund will pay the fees of Brown Brothers, which shall be agreed upon from time to time between the parties. In addition, the Fund also intends to enter into an administrative agency agreement with Brown Brothers, whereby Brown Brothers will act as the administrative agent, transfer agent and registrar for the Fund. The General Partner will also pay the fees of Brown Brothers for its services under this agreement and such fees will be determined by the parties from time to time.

# UNITED STATES BRENT OIL FUND, LP
NOTES TO STATEMENT OF FINANCIAL CONDITION

## Note 3 — Contracts and Agreements – (continued)

The Fund also entered into a brokerage agreement with UBS Securities LLC, the Futures Commission Merchant (the “FCM” or “Clearing Broker”). Pursuant to this agreement, the FCM will charge the Fund commissions at a rate to be determined per round turn trade plus applicable exchange and NFA fees for futures contracts and options on futures contracts.

## Note 4 — Financial Instruments, Off-Balance Sheet Risks and Contingencies

The Fund intends to engage in the trading of U.S. and non-U.S. futures contracts and options on U.S. and non-U.S. futures contracts (collectively “derivatives”). The Fund will be exposed to both market risk, the risk arising from changes in the market value of the contracts; and credit risk, the risk of failure by another party to perform according to the terms of a contract.

Initially, all of the contracts traded by the Fund are expected to be exchange-traded. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with over-the-counter transactions since, in over-the-counter transactions, the Fund must rely solely on the credit of its respective individual counterparties. However, in the future, if the Fund were to enter into non-exchange traded contracts, it would be subject to the credit risk associated with counterparty non-performance. The credit risk from counterparty non-performance associated with such instruments is the net unrealized gain, if any. The Fund will also incur credit risk since the sole counterparty to all domestic futures contracts is the exchange clearing corporation. In addition, the Fund bears the risk of financial failure by the Clearing Broker.

The purchase and sale of futures and options on futures contracts requires margin deposits with an FCM. Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires an FCM to segregate all customer transactions and assets from the FCM’s proprietary activities.

The Fund’s cash and other property, such as U.S. Treasury Bills, deposited with an FCM are considered commingled with all other customer funds subject to the FCM’s segregation requirements. In the event of an FCM’s insolvency, recovery may be limited to a pro rata share of segregated funds available. It is possible that the recovered amount could be less than the total of cash and other property deposited.

For derivatives, risks arise from changes in the market value of the contracts. Theoretically, the Fund will be exposed to a market risk equal to the value of futures contracts purchased and unlimited liability on such contracts sold short. As both buyer and seller of options, the Fund pays or receives a premium at the outset and then bears the risk of unfavorable changes in the price of the contract underlying the option.

The Fund’s policy is to continuously monitor its exposure to market and counterparty risk through the use of a variety of financial, position and credit exposure reporting controls and procedures. In addition, the Fund has a policy of reviewing the credit standing of each clearing broker or counterparty with which it conducts business.

The financial instruments that will be held by the Fund are reported in the statement of financial condition at market or fair value, or at carrying amounts that approximate fair value, because of their highly liquid nature and short-term maturity.

## Note 5 — Subsequent Events

In accordance with FAS 165, the Fund has performed an evaluation of subsequent events through December 10, 2009 which is the date the financial statements were available to be issued.

# REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Member of
United States Commodity Funds LLC and Subsidiaries

We have audited the accompanying consolidated statement of financial condition of United States Commodity Funds LLC (formerly Victoria Bay Asset Management, LLC) and Subsidiaries, (the “Company”) as of December 31, 2008, and the related consolidated statements of operations and other comprehensive income (loss), changes in equity (deficit) and cash flows for the year then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of United States Commodity Funds LLC (formerly Victoria Bay Asset Management, LLC) and Subsidiaries as of December 31, 2008, and the consolidated results of their operations and their cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 9, the accompanying consolidated financial statements have been restated.

(formerly Victoria Bay Asset Management, LLC)
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS AS RESTATED

## Note 1 — Organization and Operation

Victoria Bay Asset Management, LLC was formed as a single-member limited liability company in the State of Delaware on May 10, 2005. On June 13, 2008, Victoria Bay Asset Management, LLC changed its name to United States Commodity Funds LLC (the “Company”). The Company is the General Partner (the “General Partner”) of United States Oil Fund, LP (“USOF”), United States Natural Gas Fund, LP (“USNG”), United States Heating Oil Fund, LP (“USHO”) United States Gasoline Fund, LP (“USG”), United States 12 Month Oil Fund, LP (“US12OF”), United States 12 Month Natural Gas Fund, LP (“US12NG”), United States Short Oil Fund, LP (“USSO”) and United States Brent Oil Fund, LP (“USBO”). The Company is registered as a commodity pool operator with the Commodity Futures Trading Commission (“CFTC”) and is a member of the National Futures Association (“NFA”). USOF, USNG, USHO, USG, US12OF and USSO (collectively, the “Funds”) are commodity pools registered with the CFTC and members’ of the NFA that issue units that may be purchased and sold on the NYSE Arca, Inc. (“NYSE Arca”) under the ticker symbols “USO,” “UNG,” “UHN,” “UGA,” “USL” and “DNO.” USBO is a commodity pool that is in the process of registering its units that may be purchased and sold on the NYSE Arca.

USOF began trading on April 10, 2006 by purchasing futures contracts for light, sweet crude oil that are traded on the New York Mercantile Exchange (the “Exchange”). The investment objective of USOF is for the changes in percentage terms of its units’ net asset value to reflect the changes in percentage terms of the spot price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the changes in the price of the futures contract on light sweet crude oil traded on the Exchange, that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case it will be measured by the futures contract that is the next month contract to expire, less USOF’s expenses. USOF seeks to accomplish its objective through investments in futures contracts for light, sweet crude oil, other types of crude oil, heating oil, gasoline, natural gas and other petroleum-based fuels that are traded on the Exchange and other U.S. and foreign exchanges and other oil interests such as cash-settled options on futures contracts, forward contracts for crude oil, and over-the-counter transactions that are based on the price of crude oil, heating oil, gasoline, natural gas and other petroleum-based fuels, futures contracts and indices based on the foregoing.

USNG began trading on April 18, 2007 by purchasing futures contracts for natural gas that are traded on the Exchange. The investment objective of USNG is for the changes in percentage terms of its units’ net asset value to reflect the changes in percentage terms of the price of natural gas delivered to the Henry Hub, Louisiana as measured by the changes in the price of the futures contract on natural gas traded on the Exchange that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case it will be measured by the futures contract that is the next month contract to expire, less USNG’s expenses. USNG seeks to accomplish its objective through investments in futures contracts for natural gas, crude oil, heating oil, gasoline, and other petroleum-based fuels that are traded on the Exchange and other U.S. and foreign exchanges and other natural gas-related investments such as cash-settled options on futures contracts, forward contracts for natural gas, cleared swap contracts and over-the-counter transactions that are based on the price of natural gas, crude oil and other petroleum-based fuels, futures contracts and indices based on the foregoing.

US12OF began trading on December 6, 2007 by purchasing futures contracts for light, sweet crude oil that are traded on the Exchange. The investment objective of US12OF is for the changes in percentage terms of its units’ net asset value to reflect the changes in percentage terms of the price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the changes in the average of the prices of 12 futures contracts on crude oil traded on the Exchange, consisting of the near month contract to expire and the contracts for the following eleven months, for a total of 12 consecutive months’ contracts, except when the near month contract is within two weeks of expiration, in which case it will be measured by the futures contracts that are the next month contract to expire and the contracts for the following eleven consecutive months, less US12OF’s expenses. When calculating the daily movement of the average price of the 12 contracts each contract month will be equally weighted.

US12OF seeks to accomplish its objective through investments in futures contracts for light, sweet crude oil, other types of crude oil, heating oil, gasoline, natural gas, and other petroleum-based fuels that are traded on the Exchange and or other U.S. and foreign exchanges and other oil interests such as cash-settled options on futures contracts, forward contracts for oil, and over-the-counter transactions that are based on the price of oil, other petroleum-based fuels, futures contracts and indices based on the foregoing.

USG began trading on February 26, 2008 by purchasing futures contracts on gasoline that are traded on the Exchange. The investment objective of USG is for the changes in percentage terms of its units’ net asset value to reflect the changes in percentage terms of the price of unleaded gasoline, as measured by the changes in the price of the futures contract on gasoline traded on the Exchange that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case it will be measured by the futures contract that is the next month contact to expire, less USG’s expenses. USG seeks to accomplish its objective through investments in futures contracts for gasoline, crude oil, natural gas, heating oil and other petroleum-based fuels that are traded on the Exchange and other U.S. and foreign exchanges and other gasoline-related investments such as cash-settled options on futures contracts, forward contracts for gasoline, and over-the-counter transactions that are based on the price of gasoline, crude oil and other petroleum-based fuels, futures contracts and indices based on the foregoing.

USHO began trading on April 9, 2008 by purchasing futures contracts on heating oil that are traded on the Exchange.

USSO began trading on September 24, 2009 by selling futures contracts on light, sweet crude oil that are traded on the Exchange. The investment objective of USSO is for the changes in percentage terms of its units’ net asset value to inversely reflect the changes in percentage terms of the spot price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the changes in the price of the futures contract on light, sweet crude oil as traded on the 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 USSO’s expenses. USSO accomplishes its objective through investments in short positions in futures contracts for light, sweet crude oil and other types of crude oil, heating oil, gasoline, natural gas and other petroleum-based fuels that are traded on the Exchange and other crude oil-related investments such as cash-settled options on Futures Contracts, forward contracts for crude oil, and over-the-counter transactions that are based on the price of crude oil, heating oil, gasoline, natural gas and other petroleum-based fuels, futures contracts and indices based on the foregoing.

As of September 30, 2009, US12NG and USBO had not formally begun operations. US12NG’s registration statement on Form S-1 was declared effective by the SEC on November 12, 2009 and US12NG’s units began trading on the NYSE Arca on November 17, 2009.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS AS RESTATED

## Note 1 — Organization and Operation – (continued)

The Company is a wholly owned subsidiary of Wainwright Holdings, Inc. (“Wainwright”), a Delaware corporation. Wainwright is a holding company that is controlled by the president of the Company and served as the initial limited partner of the Funds.

As the General Partner of the Funds, the Company is required to evaluate the credit risk of the Funds to their futures commission merchant, oversee the purchases and sales of the Funds’ units by certain “authorized purchasers,” review the daily positions and margin requirements of the Funds, and manage the Funds’ investments. The Company also pays continuing service fees to the marketing agent for communicating with the authorized purchasers.

Financial information at September 30, 2009 and for the nine months ended September 30, 2009 is unaudited; however, such information reflects all adjustments which are, in the opinion of management, necessary for the fair presentation of the financial statements for the interim period.

## Note 2 — Summary of Significant Accounting Policies

### Principles of Consolidation

The Company, as General Partner of the Funds, has included the accounts of the Funds since their inception in the consolidated financial statements. The Company has recorded a noncontrolling (minority) interest for the amount directly owned by the limited partner (representing the limited partner interest owned by Wainwright). Subsequent to the Funds going effective with the SEC, the Company and Wainwright redeemed their partnership interests. Therefore, as of December 31, 2008, the accounts of each of the Funds, except for USSO and US12NG whose offerings had not yet commenced as of December 31, 2008, were no longer included in the accompanying consolidated statement of financial condition. All intercompany accounts and balances have been eliminated in consolidation.

### Revenue Recognition

The Company recognizes revenue in the period earned under the terms of the Funds’ respective Limited Partnership Agreements. These agreements provide for fees based upon a percentage of the daily average net asset value of the Funds. In connection with the Funds’ trading activities, commodity futures contracts, cleared swap contracts, forward contracts, physical commodities, and related options are recorded on the trade-date basis. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized gains and losses on open contracts are reflected in the statement of financial condition and represent the difference between original contract amount and market value (as determined by exchange settlement prices for futures contracts and related options and cash dealer prices at a predetermined time for forward contracts, physical commodities, and their related options) as of the last business day of the year or as of the last date of the financial statements. Changes in the unrealized gains or losses between periods are reflected in the statement of operations.

The Company earns interest on its assets on deposit at the broker at the 90-day Treasury bill rate for deposits denominated in U.S. dollars. In addition, the Funds earn interest on funds held with their custodian at prevailing market rates earned on such investments.

### General Partner Management Fee

Under the Funds’ respective Limited Partnership Agreements, the Company is responsible for investing the assets of the Funds in accordance with the objectives and policies of the Funds. In addition, the Company has arranged for one or more third parties to provide administrative, custody, accounting, transfer agency and other necessary services to the Funds. For these services, the Funds are contractually obligated to pay the Company a management fee, which is paid monthly, based on the average daily net assets of the Funds. Through December 31, 2008 USOF paid a fee equal to 0.50% per annum on average daily net assets of

$1,000,000,000 or less and 0.20% of average daily net assets that are greater than $1,000,000,000. Effective January 1, 2009, USOF pays a management fee of 0.45% per annum on its average daily net assets. USNG pays a fee equal to 0.60% per annum on average daily net assets of $1,000,000,000 or less and 0.50% of average daily net assets that are greater than $1,000,000,000. US12OF, USHO, USG and USSO each pay a fee of 0.60% per annum on their average daily net assets. US12NG pays a fee of 0.75% per annum on its average daily net assets.

The Funds pay for all brokerage fees, taxes and other expenses, including licensing fees for the use of intellectual property, registration or other fees paid to the SEC, the Financial Industry Regulatory Authority (“FINRA”) formerly the National Association of Securities Dealers, or any other regulatory agency in connection with the offer and sale of subsequent units after their initial registration and all legal, accounting, printing and other expenses associated therewith. The Funds also pay the fees and expenses of the independent directors.

### Investments

The Company’s investments in common stock are classified as available-for-sale-securities and are considered to be held for an indefinite period. Securities investments not classified as either held-to-maturity or trading securities are classified as available-for-sale securities. Available-for-sale-securities are recorded at fair value on the statement of financial condition, with the change in fair value excluded from earnings and recorded as a component of other comprehensive income (loss) included in member’s equity. Unrealized holding gain (loss) on such securities, which were added to (subtracted from) member’s equity were $(6,324) and $(88,820) for the period ended September 30, 2009 and the year ended December 31, 2008 (Note 7).

Realized gains or losses are recorded upon disposition of investments calculated based upon the difference between the proceeds and the cost basis determined using the specific identification method.

### Brokerage Commissions

Brokerage commissions on all open commodity futures contracts are accrued on a full-turn basis.

### Additions and Redemptions

Authorized purchasers may purchase creation baskets of the Funds only in blocks of 100,000 units equal to the net asset value of the units calculated shortly after the close of the core trading session on the NYSE Arca on the day the order is placed. Authorized purchasers may redeem units from the Funds only in blocks of 100,000 units called “Redemption Baskets.” The amount of the redemption proceeds for a Redemption Basket will be equal to the net asset value of the Funds’ units in the Redemption Basket as of the end of each business day.

The Funds receive or pay the proceeds from units sold or redeemed within three business days after the trade-date of the purchase or redemption. The amounts due from authorized purchasers are reflected in the Funds’ statement of financial condition as receivables for units sold, and amounts payable to authorized purchasers upon redemption are reflected as payable for units redeemed.

### Partnership Capital and Allocation of Partnership Income and Losses

Profit or loss shall be allocated among the partners of the Funds in proportion to the number of units each partner holds as of the close of each month. The Company, as General Partner may revise, alter or otherwise modify this method of allocation as described in the Limited Partnership Agreements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS AS RESTATED

## Note 2 — Summary of Significant Accounting Policies – (continued)

### Calculation of Net Asset Value

The Funds calculate their net asset value on each NYSE Arca trading day by taking the current market value of their total assets, subtracting any liabilities and dividing the amount by the total number of units issued and outstanding. The Funds use the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange.

### Cash Equivalents

Cash equivalents are highly liquid investments with original maturity dates of three months or less.

### Accounting Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

### Income Taxes

The Company has filed an election with the Internal Revenue Service to be treated as an association taxable as a corporation. The Company files a consolidated federal income tax return with Wainwright and provides for income taxes as if the Company filed separately. The Company, however, does not file on a consolidated basis for state income tax purposes. The Company accounts for income taxes in accordance with Accounting Standards Classification Topic 740-10, Accounting for Income Taxes. Under the asset and liability method of FASB ASC Topic 740-10, deferred tax assets and liabilities are recognized for the estimated future tax consequences or benefits attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled.

### Deferred Offering Costs

The Company capitalizes all initial offering costs associated with the registration of the Funds until such time as the registration process with the SEC is complete. At this time, the Company charges the capitalized costs to member’s equity. Deferred offering costs includes, but is not limited to, legal fees pertaining to the Funds’ units offered for sale, SEC and state registration fees, initial fees paid to be listed on an exchange and underwriting and other similar costs.

### Recent Accounting Pronouncements

Effective January 1, 2008, the Company adopted Financial Accounting Standards Board Accounting Standards Codification Topic 740-10, Accounting for Uncertainty in Income Taxes, which establishes that a tax position taken or expected to be taken in a tax return is to be recognized in the consolidated financial statements when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. FASB ASC Topic 740-10 is effective for private companies for fiscal years beginning after December 15, 2008. The Company’s adoption of FASB ASC Topic 740-10 did not have a material effect on its consolidated financial position, results of operations or liquidity.

Effective January 1, 2008, the Company adopted FASB ASC Topic 820, Fair Value Measurements and Disclosures. FASB ASC Topic 820 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurement. The changes to past practice resulting from the application of FASB ASC Topic 820 relate to the definition of fair value,

the methods used to measure fair value, and the expanded disclosures about fair value measurement. ASC 820 establishes a fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from sources independent of the Company (observable inputs) and (2) the Company’s own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the FASB ASC Topic 820 hierarchy are as follows:

Level I – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level II – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level II assets include the following: quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market-corroborated inputs).

Level III – Unobservable pricing input at the measurement date for the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available.

In some instances, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest input level that is significant to the fair value measurement in its entirety. The Company’s adoption of FASB ASC Topic 820 did not have a material effect on its consolidated financial position, results of operations or liquidity.

In December 2007, the FASB issued FASB ASC Topic 810-10-65, Non-controlling Interests in Consolidated Financial Statements, an amendment of ARB No. 51. FASB ASC Topic 810-10-65 requires all entities to report noncontrolling (minority) interests in subsidiaries as equity in the consolidated financial statements. Additionally, FASB ASC Topic 810-10-65 requires that transactions between an entity and noncontrolling interests be treated as equity transactions. FASB ASC Topic 810-10-65 is effective for fiscal years beginning after December 15, 2008. Adoption on January 1, 2009, as required, did not have a material effect on the Company’s financial condition, results of operations or liquidity. The minority interests previously reflected in the Company’s financial statements have been reclassified to conform to the current presentation.

In March 2008, the FASB released FASB ASC Topic 815-10, Disclosures about Derivative Instruments and Hedging Activities. FASB ASC Topic 815-10 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. The Company adopted Statement No. 161 on January 1, 2009. The Company’s adoption of FASB ASC Top 815-10 did not have a material effect on the Company’s financial condition, results of operations or liquidity.

In May 2009, the FASB issued FASB ASC Topic 855-10-05, Subsequent Events. This standard is intended to establish general standards of accounting for and disclosures of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. Specifically, this standard sets forth the period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements, the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements, and the disclosures that an entity should make about events or transactions that occurred after the balance sheet date. FASB ASC Topic 855-10-05 is effective for fiscal years and interim periods ending after June 15, 2009.

During the period ended September 30, 2009 and the year ended December 31, 2008, the Company paid $327,500 and $784,837 in distributions to its member. During the year ended December 31, 2007, Wainwright contributed $1,280,906 in marketable securities in connection with its interest in the Company. In addition, the Company and USOF have incurred offering and organizational costs in the amount of $2,023,991 which are not included in the accompanying consolidated financial statements at December 31, 2008. Wainwright has provided funding for these costs, but is under no obligation to do so or continue funding these costs. The Company and USOF are not required to reimburse Wainwright or its affiliates for any such costs incurred. On June 1, 2007, accounts payable of $480,593 relating to USOF’s offering costs incurred but unpaid by Wainwright were assumed by the Company in connection with Wainwright’s equity infusion of marketable securities as mentioned above. The effect of this transaction increased investments by $1,280,906, offering costs by $480,593, accounts payable by $480,593 and equity by $1,280,906. Included in deferred offering costs at December 31, 2008 (for US12NG and USSO) and December 31, 2007 (for US12NG, USG and USHO) is $352,794 and $187,056 respectively, of initial offering and organizational costs incurred by the Funds. These initial offering and organization costs incurred by the Funds will be borne by the Company and not be charged to the Funds.

The Funds were each capitalized with $1,000, of which the Company contributed $20 and Wainwright contributed $980.

In addition, the Company, as General Partner, through no obligation to do so, has agreed to pay certain expenses, including those relating to audit expenses and tax accounting and reporting requirements normally borne by USHO, USG and US12OF to the extent that such expenses exceed 0.15% (15 basis points) of their NAV, on an annualized basis, through September 30, 2009 and December 31, 2008. The Company, as General Partner has no obligation to continue such payments in subsequent years. No payments have been made to US12OF following the quarter ended March 31, 2009.

## Note 5 — Income Taxes

The Company has filed an election with the Internal Revenue Service to be treated as an association taxable as a corporation. The Company files a consolidated federal income tax return with Wainwright and provides for income taxes as if the Company filed separately. The Company, however, does not file on a consolidated basis for state income tax purposes. In connection with filing a consolidated federal income tax return, the Company has recorded federal income tax expense (benefit) and has recorded a corresponding due from parent and due to parent for its federal tax liability (benefit).

Deferred tax assets and liabilities reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax liabilities and assets as of September 30, 2009 and December 31, 2008 are as follows:

|  | September 30, 2009 |  | December 31, 2008
|  | (Unaudited) |  |
Deferred tax liabilities |  | $ | — |  |  | $ | — |
Deferred tax assets: |  |  |  |  |  |  |  |
Unrealized losses on investments |  |  | 226,000 |  |  |  | 224,000 |
Valuation allowance for deferred tax asset |  |  | (226,000 | ) |  |  | (224,000 | )
|  | $ | — |  |  | $ | — |

The valuation allowance increased by $2,000 for the period ended September 30, 2009 and increased by $38,000 for the year ended December 31, 2008.

The deferred tax asset shown above relates to the unrealized losses on investments and is accounted for as other comprehensive loss (see Note 7).

## Note 6 — Contracts and Agreements – (continued)

The Company and each of the Funds are parties to custodian agreements with Brown Brothers Harriman & Co. (“Brown Brothers”), whereby Brown Brothers holds investments on behalf of the Funds. The Company pays the fees of the custodian, which shall be determined by the parties from time to time. In addition, the Company, with each of the Funds, are parties to administrative agency agreements with Brown Brothers, whereby Brown Brothers acts as the administrative agent, transfer agent and registrar for each of the Funds. The Company also pays the fees of Brown Brothers for its services under these agreements and such fees will be determined by the parties from time to time.

Currently, the Company pays Brown Brothers for its services, in the foregoing capacities, the greater of a minimum amount of $75,000 annually or an asset-based charge of (a) 0.06% for the first $500 million of combined net assets, (b) 0.0465% for combined net assets greater than $500 million but less than $1 billion, and (c) 0.035% of combined net assets in excess of $1 billion. The Company also pays a $20,000 annual fee for transfer agency services and transaction fees ranging from $7.00 to $15.00 per transaction.

Each of the Funds have entered into brokerage agreements with UBS Securities LLC as the Futures Commission Merchant (the “FCM”). The agreements provide that the FCM will charge commissions of approximately $7 to $8 per round-turn trade plus applicable exchange and NFA fees for futures contracts and options on futures contracts.

Each of the Funds has invested primarily in futures contracts traded on the Exchange since the commencement of its operations. On May 30, 2007, USOF and USNG entered into a license agreement with the Exchange whereby the Funds were granted a non-exclusive license to use certain of the Exchange’s settlement prices and service marks. The agreement has an effective date of April 10, 2006. Under the license agreement, the Funds pay the Exchange an asset-based fee for the license. Pursuant to the agreement, the Funds pay a licensing fee that is equal to 0.04% for the first $1,000,000,000 of combined assets of the Funds and 0.02% for combined assets above $1,000,000,000. US12OF, USG, USHO and USSO entered into the above license agreement on the same terms with an effective date of December 4, 2007. Other funds managed by the Company will also be granted a similar non-exclusive license on the same terms.

The Funds expressly disclaim any association with the Exchange or endorsement of the Funds by the Exchange and acknowledge that “NYMEX” and “New York Mercantile Exchange” are registered trademarks of such Exchange.

The Company has contracted an accounting firm to prepare each of the Funds’ yearly income tax filings with the Internal Revenue Service. The yearly cost to the Company for these services is estimated to be and aggregate of approximately $525,000 for all of the Funds. The cost associated with any registered new fund is expected to be comparable.

## Note 7 — Accumulated other Comprehensive Loss

Balance, December 31, 2007 |  | $ | (433,189 | )

## Note 8 — Off-Balance Sheet Risks and Contingencies

The Funds engage in the trading of U.S. futures contracts, options on U.S. contracts, cleared swap contracts and over-the-counter derivative transactions (collectively “derivatives”). The Funds are exposed to both market risk, the risk arising from changes in the market value of the contracts; and credit risk, the risk of failure by another party to perform according to the terms of a contract.

All of the contracts currently traded by the Funds, with the exception of USNG, are exchange-traded. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with over-the-counter transactions since, in over-the-counter transactions; the Funds must rely solely on the credit of their respective individual counterparties. To the extent the Funds enter into non-exchange traded contracts, they are subject to the credit risk associated with counterparty non-performance. The credit risk from counterparty non-performance associated with such instruments is the net unrealized gain, if any. The Funds also have credit risk since the sole counterparty to all domestic futures contracts is the exchange clearing corporation. In addition, the Funds bear the risk of financial failure by the clearing broker.

The purchase and sale of futures and options on futures contracts require margin deposits with an FCM. Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires an FCM to segregate all customer transactions and assets from the FCM’s proprietary activities.

A customer’s cash and other property, such as U.S. Treasury Bills, deposited with an FCM are considered commingled with all other customer funds subject to the FCM’s segregation requirements. In the event of an FCM’s insolvency, recovery may be limited to a pro rata share of segregated funds available. It is possible that the recovered amount could be less than the total of cash and other property deposited.

For derivatives, risks arise from changes in the market value of the contracts. Theoretically, the Funds are exposed to market risk equal to the value of futures and forward contracts purchased and unlimited liability on such contracts sold short. As both buyers and sellers of options, the Funds pay or receive a premium at the outset and then bear the risk of unfavorable changes in the price of the contract underlying the option.

The Company’s policy is to continuously monitor its exposure to market and counterparty risk through the use of a variety of financial, position and credit exposure reporting and control procedures. In addition, the Company has a policy of reviewing the credit standing of each clearing broker or counter-party with which it conducts business.

The financial instruments held by the Company are reported in the statement of financial condition at market or fair value, or at carrying amounts that approximate fair value, because of their highly liquid nature and short-term maturities.

The Company has securities for its own account and may incur losses if the market value of the securities decreases subsequent to September 30, 2009.

The Company has a substantial portion of its assets on deposit with banks. Assets deposited with banks are subject to credit risk. In the event of a bank's insolvency, recovery of the Company's assets on deposit may be limited to account insurance or other protection afforded such deposits. As of September 30, 2009, the Company had cash of $4,120,296 in excess of the federally insured amount of $250,000.

## Note 9 — Restatement of Consolidated Financial Statements

During 2009, the Company’s management concluded that there were errors associated with the Company’s accounting for income taxes. The Company was formed as a single-member limited liability company which is a disregarded entity for federal income tax purposes. However, the Company filed an election with the Internal Revenue Service to treat the Company as an association taxable as a corporation. As a result of the error in accounting for income taxes, the income tax payable, member distributions, income tax provision (benefit) and due from and to parent were restated for the year ending December 31, 2008.

The rights and liabilities of the Partners shall be as set forth in the Act, except as herein otherwise expressly provided. The Partnership shall continue without interruption as a limited partnership pursuant to the provisions of the Act.

2.2 The name of the Partnership shall be United States Brent Oil Fund, LP; however, the business of the Partnership may be conducted, upon compliance with all applicable laws, under any other name designated in writing by the General Partner to the Limited Partners.

The General Partner shall establish and maintain an audit committee of its board of directors for the Partnership (the “Audit Committee”) in compliance with, and granted the requisite authority and funding pursuant to, any applicable (1) federal securities laws and regulations, including the Sarbanes-Oxley Act of 2002, and (2) rules, policies and procedures of any national securities exchange on which the securities issued by the Partnership are listed and traded.

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.

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

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 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.

Except as otherwise expressly provided in this Agreement, the General Partner is hereby granted the right, power and authority to do on behalf of the Partnership all things which, in its sole judgment, are necessary, proper or desirable to carry out the aforementioned duties and responsibilities, including but not limited to, the right, power and authority from time to time to do the following:

(c) the acquisition, disposition, mortgage, pledge, encumbrance, hypothecation or exchange of any or all of the assets of the Partnership, or the merger or other combination of the Partnership with or into another Person (the matters described in this clause (c) being subject, however, to any prior approval that may be required in accordance with this Agreement);

(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.

7.3 Right of Public to Rely on Authority of a General Partner. No person shall be required to determine the General Partner’s authority to make any undertaking on behalf of the Partnership.

7.4 Obligation of the General Partner. The General Partner shall:

(b) maintain the Capital Account for each Partner; and

(c) cause the Partnership to enter into and carry out the obligations of the Partnership contained in the agreements with Affiliates of the General Partner as described in the Prospectus and cause the Partnership not to take any action in violation of such agreements.

7.5 Good Faith. The General Partner has a responsibility to the Limited Partners to exercise good faith and fairness in all dealings. In the event that a Limited Partner believes that the General Partner has violated its fiduciary duty to the Limited Partners, he may seek legal relief individually or on behalf of the Partnership under applicable laws, including under the Act and under securities and commodities laws, to recover damages from or require an accounting by the General Partner. 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

B-12

TABLE OF CONTENTS

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.

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; 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.

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

B-13

TABLE OF CONTENTS

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.

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.

RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

8.1 No Participation in Management.

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,

TABLE OF CONTENTS

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

(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

B-15

TABLE OF CONTENTS

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

B-16

TABLE OF CONTENTS

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.

(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.

B-17

TABLE OF CONTENTS

(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.

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.

B-18

TABLE OF CONTENTS

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.

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.

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.

B-20

TABLE OF CONTENTS

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.

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 (10th) 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

B-21

TABLE OF CONTENTS

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.

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.

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.

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.

# 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 100,000 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.

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 Limited Partner’s 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.

# 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

B-28

TABLE OF CONTENTS

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., one basket) or less, unless the General Partner has reason to believe that the party placing the redemption order does in fact possess all the outstanding units and can deliver them.

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.

TABLE OF CONTENTS

## The Commodity Interest Markets

### General

The Commodity Exchange Act or CEA governs the regulation of commodity interest transactions, markets and intermediaries. In December 2000, the CEA was amended by the Commodity Futures Modernization Act of 2000, or CFMA, which substantially revised the regulatory framework governing certain commodity interest transactions and the markets on which they trade. The CEA, as amended by the CFMA, now provides for varying degrees of regulation of commodity interest transactions depending upon the variables of the transaction. In general, these variables include (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. Information regarding commodity interest transactions, markets and intermediaries, and their associated regulatory environment, is provided below.

### Futures Contracts

A futures contract such as a Brent crude oil 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.

SAI-3

TABLE OF CONTENTS

The forward markets provide what has typically been a highly liquid market for foreign exchange trading, and in certain cases the prices quoted for foreign exchange forward contracts may be more favorable than the prices for foreign exchange futures contracts traded on U.S. exchanges. The forward markets are largely unregulated. Forward contracts are, in general, not cleared or guaranteed by a third party. Commercial banks participating in trading foreign exchange forward contracts often do not require margin deposits, but rely upon internal credit limitations and their judgments regarding the creditworthiness of their counterparties. In recent years, however, many over-the-counter market participants in foreign exchange trading have begun to require that their counterparties post margin.

Further, as the result of the CFMA, over-the-counter derivative instruments such as forward contracts and swap agreements (and options on forwards and physical commodities) may begin to be traded on lightly-regulated exchanges or electronic trading platforms that may, but are not required to, provide for clearing facilities. Exchanges and electronic trading platforms on which over-the-counter instruments may be traded and the regulation and criteria for that trading are more fully described below under “Futures Exchanges and Clearing Organizations.” Nonetheless, absent a clearing facility, USBO’s trading in foreign exchange and other forward contracts is exposed to the creditworthiness of the counterparties on the other side of the trade.

### Options on Futures Contracts

Options on futures contracts are standardized contracts traded on an exchange. An option on 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

SAI-4

TABLE OF CONTENTS

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 recently, as a result of regulatory changes enacted as part of the CFMA, certain swap contracts are now being 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 to any collateral deposits it is holding.

### Block Trading

Block Trading refers to privately negotiated futures or option transactions executed apart from the public auction market. A block transaction may be executed either on or off the exchange trading floor but is still reported to and cleared by the exchange.

### Exchange for Physical

An Exchange for Physical (EFP) is an off market transaction which involves the swapping (or exchanging) of an over-the-counter (OTC) position for a futures position. The OTC transaction must be for the same or similar quantity or amount of a specified commodity, or a substantially similar commodity or instrument. The OTC side of the EFP can include swaps, swap options, or other instruments traded in the OTC market.

In order that an EFP transaction can take place, the OTC side and futures components must be “substantially similar” in terms of either value and or quantity. The net result is that the OTC position (and the inherent counterparty credit exposure) is transferred from the OTC market to the futures market. EFPs can also work in reverse, where a futures position can be reversed and transferred to the OTC market.

### Exchange for Swap

A technique, analogous to an EFP transaction used by financial institutions to avoid taking physical delivery of commodities. A dealer takes the financial institution’s futures positions into its own account and swaps the commodity return for a funding rate.

### Participants

The two broad classes of persons who trade commodities are hedgers and speculators. Hedgers include financial institutions that manage or deal in interest rate-sensitive instruments, foreign currencies or stock portfolios, and commercial market participants, such as farmers and manufacturers, that market or process commodities. Hedging is a protective procedure designed to lock in profits that could otherwise be lost due to an adverse movement in the underlying commodity, for example, the adverse price movement between the time a merchandiser or processor enters into a contract to buy or sell a raw or processed commodity at a certain price and the time he must perform the contract. In such a case, at the time the hedger contracts to physically sell the commodity at a future date he will simultaneously buy a futures or forward contract for the necessary equivalent quantity of the commodity. At the time for performance of the contract, the hedger may accept delivery under his futures contract and sell the commodity quantity as required by his physical contract or he may buy the actual commodity, sell if under the physical contract and close out his position by making an offsetting sale of a futures contract.

TABLE OF CONTENTS

The commodity interest markets enable the hedger to shift the risk of price fluctuations. The usual objective of the hedger is to protect the profit that he expects to earn from farming, merchandising, or processing operations rather than to profit from his trading. However, at times the impetus for a hedge transaction may result in part from speculative objectives.

Unlike the hedger, the speculator generally expects neither to make nor take delivery of the underlying commodity. Instead, the speculator risks his capital with the hope of making profits from price fluctuations in the commodities. The speculator is, in effect, the risk bearer who assumes the risks that the hedger seeks to avoid. Speculators rarely make or take delivery of the underlying commodity; rather they attempt to close out their positions prior to the delivery date. Because the speculator may take either a long or short position in commodities, it is possible for him to make profits or incur losses regardless of whether prices go up or down.

### Futures Exchanges and Clearing Organizations

Futures exchanges provide centralized market facilities in which multiple persons have the ability to execute or trade contracts by accepting bids and offers from multiple participants. Futures exchanges may provide for execution of trades at a physical location utilizing trading pits and/or may provide for trading to be done electronically through computerized matching of bids and offers pursuant to various algorithms. Members of a particular exchange and the trades executed on such exchange are subject to the rules of that exchange. Futures exchanges and clearing organizations are given reasonable latitude in promulgating rules and regulations to control and regulate their members. Examples of regulations by exchanges and clearing organizations include the establishment of initial margin levels, rules regarding trading practices, contract specifications, speculative position limits, daily price fluctuation limits, and execution and clearing fees.

Clearing organizations provide services designed to mutualize or transfer the credit risk arising from the trading of contracts on an exchange or other electronic trading facility. Once trades made between members of an exchange or electronic trading facility have been confirmed, the clearing organization becomes substituted for the clearing member acting on behalf of each buyer and each seller of contracts traded on the exchange or trading platform and in effect becomes the other party to the trade. Thereafter, each clearing member party to the trade looks only to the clearing organization for performance. The clearing organization generally establishes some sort of security or guarantee fund to which all clearing members of the exchange must contribute; this fund acts as an emergency buffer that is intended to enable the clearing organization to meet its obligations with regard to the other side of an insolvent clearing member’s contracts. Furthermore, the clearing organization requires margin deposits and continuously marks positions to market to provide some assurance that its members will be able to fulfill their contractual obligations. Thus, a central function of the clearing organization is to ensure the integrity of trades, and members effecting transactions on an exchange need not concern themselves with the solvency of the party on the opposite side of the trade; their only remaining concerns are the respective solvencies of their own customers, their clearing broker and the clearing organization. The clearing organizations do not deal with customers, but only with their member firms and the guarantee of performance for open positions provided by the clearing organization does not run to customers.

### U.S. Futures Exchanges

Futures exchanges in the United States are subject to varying degrees of regulation by the CFTC based on their designation as one of the following: a designated contract market, a derivatives transaction execution facility, an exempt board of trade or an electronic trading facility.

A designated contract market is the most highly regulated level of futures exchange. Designated contract markets may offer products to retail customers on an unrestricted basis. To be designated as a contract market, the exchange must demonstrate that it satisfies specified general criteria for designation, such as having the ability to prevent market manipulation, rules and procedures to ensure fair and equitable trading, position limits, dispute resolution procedures, minimization of conflicts of interest and protection of market participants. Among the principal designated contract markets in the United States are the Chicago Board of Trade, the Chicago Mercantile Exchange and the New York Mercantile Exchange. Each of the designated contract markets in the United States must provide for the clearance and settlement of transactions with a CFTC-registered derivatives clearing organization.

SAI-6

TABLE OF CONTENTS

A derivatives transaction execution facility, or DTEF, is a new type of exchange that is subject to fewer regulatory requirements than a designated contract market but is subject to both commodity interest and participant limitations. DTEFs limit access to eligible traders that qualify as either eligible contract participants or eligible commercial entities for futures and option contracts on commodities that have a nearly inexhaustible deliverable supply, are highly unlikely to be susceptible to the threat of manipulation, or have no cash market, security futures products, and futures and option contracts on commodities that the CFTC may determine, on a case-by-case basis, are highly unlikely to be susceptible to the threat of manipulation. In addition, certain commodity interests excluded or exempt from the CEA, such as swaps, etc. may be traded on a DTEF. There is no requirement that a DTEF use a clearing organization, except with respect to trading in security futures contracts, in which case the clearing organization must be a securities clearing agency. However, if futures contracts and options on futures contracts on a DTEF are cleared, then it must be through a CFTC-registered derivatives clearing organization, except that some excluded or exempt commodities traded on a DTEF may be cleared through a clearing organization other than one registered with the CFTC.

An exempt board of trade is also a newly designated form of exchange. An exempt board of trade is substantially unregulated, subject only to CFTC anti-fraud and anti-manipulation authority. An exempt board of trade is permitted to trade futures contracts and options on futures contracts provided that the underlying commodity is not a security or securities index and has an inexhaustible deliverable supply or no cash market. All traders on an exempt board of trade must qualify as eligible contract participants. Contracts deemed eligible to be traded on an exempt board of trade include contracts on interest rates, exchange rates, currencies, credit risks or measures, debt instruments, measures of inflation, or other macroeconomic indices or measures. There is no requirement that an exempt board of trade use a clearing organization. However, if contracts on an exempt board of trade are cleared, then it must be through a CFTC-registered derivatives clearing organization. A board of trade electing to operate as an exempt board of trade must file a written notification with the CFTC.

An electronic trading facility is a new form of exchange that operates by means of an electronic or telecommunications network and maintains an automated audit trail of bids, offers, and the matching of orders or the execution of transactions on the electronic trading facility. The CEA does not apply to, and the CFTC has no jurisdiction over, transactions on an electronic trading facility in certain excluded commodities that are entered into between principals that qualify as eligible contract participants, subject only to CFTC anti-fraud and anti-manipulation authority. In general, excluded commodities include interest rates, currencies, securities, securities indices or other financial, economic or commercial indices or measures.

The General Partner intends to monitor the development of and opportunities and risks presented by the new less-regulated exchanges and exempt boards and may, in the future, allocate a percentage of USBO’s assets to trading in products on these exchanges. Provided USBO maintains assets exceeding $5 million, USBO would qualify as an eligible contract participant and thus would be able to trade on such exchanges.

### Non-U.S. Futures Exchanges

Non-U.S. futures exchanges differ in certain respects from their U.S. counterparts. Importantly, non-U.S. futures exchanges are generally not subject to regulation by the CFTC, but rather are regulated by their home country regulator. Although not general subject to regulation by the CFTC, non-U.S. futures exchanges may become subject to CFTC reporting and oversight authorities if they trade U.S.-linked futures contracts or contracts with a significant price discovery function.

In contrast to U.S. designated contract markets, some non-U.S. exchanges are principals’ markets, where trades remain the liability of the traders involved, and the exchange or an affiliated clearing organization, if any, does not become substituted for any party. Due to the absence of a clearing system, such exchanges are significantly more susceptible to disruptions. Further, participants in such markets must often satisfy themselves as to the individual creditworthiness of each entity with which they enter into a trade. The principal non-U.S. futures exchange in which USBO expects to invest is the ICE Futures Exchange. Futures Contracts traded on the ICE Futures Exchange, including the Benchmark Futures Contract, are backed by the ICE Futures Exchange and may not expose USBO to the risks of some other non-U.S. exchanges or clearing corporations that do not have such backing.

SAI-7

TABLE OF CONTENTS

Trading on non-U.S. exchanges is often in the currency of the exchange’s home jurisdiction. Consequently, USBO is subject to the additional risk of fluctuations in the exchange rate between such currencies and U.S. dollars and the possibility that exchange controls could be imposed in the future. The Benchmark Futures Contract, however, is traded in U.S. dollars and does not expose USBO to the risk of currency fluctuations. Trading on non-U.S. exchanges may differ from trading on U.S. exchanges in a variety of ways and, accordingly, may subject USBO to additional risks.

### Accountability Levels and Position Limits

The CFTC and U.S. designated contract markets 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 a hedger, which USBO is not) may hold, own or control. Among the purposes of accountability levels and position limits is to prevent a corner or squeeze on a market or undue influence on prices by any single trader or group of traders. The position limits currently established by the CFTC apply to certain agricultural commodity interests, such as grains (oats, barley, and flaxseed), soybeans, corn, wheat, cotton, eggs, rye, and potatoes, but not to interests in energy products. In addition, U.S. exchanges may set accountability levels and position limits for all commodity interests traded on that exchange. For example, the current accountability level for investments at any one time in light, sweet oil Futures Contracts on the New York Mercantile Exchange is 20,000 contracts. The New York Mercantile Exchange also imposes position limits on contracts held in the last few days of trading in the near month contract to expire. Certain exchanges or clearing organizations also set limits on the total net positions that may be held by a clearing broker. For purposes of determining accountability levels and position limits USBO’s commodity interest positions will not be attributable to investors in their own commodity interest trading.

In general, no position limits are in effect in forward or other over-the-counter contract trading or in trading on non-U.S. futures exchanges, although the principals with which USBO and the clearing brokers may trade in such markets may impose such limits as a matter of credit policy. For example, the Benchmark Futures Contract is currently traded on the ICE Futures Exchange without specific accountability levels or position limits. However, the ICE Futures Exchange’s daily position management regime requires that any position greater than 500 contracts in the nearest two months to expire must be reported to the ICE Futures Exchange on a daily basis. The ICE Futures Exchange has powers to prevent the development of excessive positions or unwarranted speculation or any other undesirable situation and may take any steps necessary to resolve such situations including the ability to mandate limitations on the size of such positions or to reduce positions where appropriate. Although the Benchmark Futures Contract is not subject to the same accountability levels and position limits established by U.S. designated contract markets, recent actions by the ICE Futures Exchange indicate that the exchange is actively using its oversight authority to regulate positions in its contracts.

### Daily Price Limits

Most U.S. futures exchanges (but generally not non-U.S. exchanges) limit the amount of fluctuation in some futures contract or options on a futures contract prices during a single trading period by regulations. These regulations specify what are referred to as daily price fluctuation limits or more commonly, daily limits. The daily limits establish the maximum amount that the price of a futures or option on a futures contract may vary either up or down from the previous day’s settlement price. Once the daily limit has been reached in a particular futures or options on futures contract, no trades may be made at a price beyond the limit. Positions in the futures or options contract may then be taken or liquidated, if at all, only at inordinate expense or if traders are willing to effect trades at or within the limit during the period for trading on such day. Because the daily limit rule governs price movement only for a particular trading day, it does not limit losses and may in fact substantially increase losses because it may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved the daily limit for several consecutive trading days, thus preventing prompt liquidation of positions and subjecting the trader to substantial losses for those days. The concept of daily price limits is not relevant to over-the-counter contracts, including forwards and swaps, and thus such limits are not imposed by banks and others who deal in those markets.

SAI-8

TABLE OF CONTENTS

In contrast, the New York Mercantile Exchange does not impose daily limits but rather limits the amount of price fluctuation for light, sweet crude oil Futures Contracts. For example, the New York Mercantile Exchange imposes a $10.00 per barrel ($10,000 per contract) price fluctuation limit for light, sweet crude oil Futures Contracts. This limit is initially based off the previous trading day’s settlement price. If any light, sweet crude oil Futures Contract is traded, bid, or offered at the limit for five minutes, trading is halted for five minutes. When trading resumes it begins at the point where the limit was imposed and the limit is reset to be $10.00 per barrel in either direction of that point. If another halt were triggered, the market would continue to be expanded by $10.00 per barrel in either direction after each successive five-minute trading halt. There is no maximum price fluctuation limit during any one trading session.

### Commodity Prices

Commodity prices are volatile and, although ultimately determined by the interaction of supply and demand, are subject to many other influences, including the psychology of the marketplace and speculative assessments of future world and economic events. Political climate, interest rates, treaties, balance of payments, exchange controls and other governmental interventions as well as numerous other variables affect the commodity markets, and even with comparatively complete information it is impossible for any trader to predict reliably commodity prices.

### 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, DTEF, exempt board of trade or electronic trading facility. Derivatives clearing organizations are also subject to the CEA and CFTC regulation. 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 possesses exclusive jurisdiction to regulate the activities of commodity pool operators and commodity trading advisors and has adopted regulations with respect to the activities of those persons and/or entities. Under the CEA, a registered commodity pool operator, such as the General Partner, is required to make annual filings with the CFTC describing its organization, capital structure, management and controlling persons. In addition, the CEA authorizes the CFTC to require and review books and records of, and documents prepared by, registered commodity pool operators. Pursuant to this authority, the CFTC requires commodity pool operators to keep accurate, current and orderly records for each pool that they operate. The CFTC may suspend the registration of a commodity pool operator (1) if the CFTC finds that the operator’s trading practices tend to disrupt orderly market conditions, (2) if any controlling person of the operator is subject to an order of the CFTC denying such person trading privileges on any exchange, and (3) in certain other circumstances. Suspension, restriction or termination of the General Partner’s registration as a commodity pool operator would prevent it, until that registration were to be reinstated, from managing USBO, and might result in the termination of USBO. USBO itself is not required to be registered with the CFTC in any capacity.

The CEA gives the CFTC similar authority with respect to the activities of commodity trading advisors. If a trading advisor’s commodity trading advisor registration were to be terminated, restricted or suspended, the trading advisor would be unable, until the registration were to be reinstated, to render trading advice to USBO.

The CEA requires all futures commission merchants, 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,

SAI-9

TABLE OF CONTENTS

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.

USBO’s investors are afforded prescribed rights for reparations under the CEA. Investors may also be able to maintain a private right of action for violations of the CEA. The CFTC has adopted rules implementing the reparation provisions of the CEA, which provide that any person may file a complaint for a reparations award with the CFTC for violation of the CEA against a floor broker or a futures commission merchant, introducing broker, commodity trading advisor, commodity pool operator, and their respective associated persons.

Pursuant to authority in the CEA, the NFA has been formed and registered with the CFTC as a registered futures association. At the present time, the NFA is the only self-regulatory organization for commodity interest professionals, other than futures exchanges. The CFTC has delegated to the NFA responsibility for the registration of commodity trading advisors, commodity pool operators, futures commission merchants, introducing brokers, and their respective associated persons and floor brokers. The General Partner, each trading advisor, the selling agents and the clearing brokers are members of the NFA. As such, they are subject to NFA standards relating to fair trade practices, financial condition and consumer protection. USBO itself is not required to become a member of the NFA. As the self-regulatory body of the commodity interest industry, the NFA promulgates rules governing the conduct of professionals and disciplines those professionals that do not comply with these rules. The NFA also arbitrates disputes between members and their customers and conducts registration and fitness screening of applicants for membership and audits of its existing members.

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.

The function of the CFTC is to implement the objectives of the CEA of preventing price manipulation and other disruptions to market integrity, avoiding systemic risk, preventing fraud and promoting innovation, competition and financial integrity of transactions. As mentioned above, this regulation, among other things, provides that the trading of commodity interest contracts generally must be upon exchanges designated as contract markets or DTEFs and that all trading on those exchanges must be done by or through exchange members. Under the CFMA, commodity interest trading in some commodities between sophisticated persons may be traded on a trading facility not regulated by the CFTC. As a general matter, trading in spot contracts, forward contracts, options on forward contracts or commodities, or swap contracts between eligible contract participants is not within the jurisdiction of the CFTC and may therefore be effectively unregulated. The trading advisors may engage in those transactions on behalf of USBO in reliance on this exclusion from regulation.

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.

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.

SAI-10

TABLE OF CONTENTS

The CFTC is currently prohibited by statute from regulating trading on non-U.S. futures exchanges and markets. The CFTC, however, has adopted regulations relating to the marketing of non-U.S. futures contracts in the United States. These regulations permit certain contracts traded on non-U.S. exchanges to be offered and sold in the United States. Additionally, the CFTC has some oversight authority and the ability to impose certain self-regulatory and reporting requirements on non-U.S. futures exchanges trading U.S.-lined future contracts and contracts with a significant price discovery function.

### 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 2%) 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.

Trading in the over-the-counter markets where no clearing facility is provided generally does not require margin but generally does require the extension of credit between counterparties.

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 Brent crude oil and Futures Contracts and Other Oil Interests 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

SAI-11

TABLE OF CONTENTS

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-a-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.

### Interest Income

Unlike some alternative investment funds, USBO does not borrow money in order to obtain leverage, so USBO does not incur any interest expense. Rather, USBO’s margin deposits are maintained in Treasuries and interest is earned on 100% of USBO’s available assets, which include unrealized profits credited to USBO’s accounts.

## 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 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.

II-3

TABLE OF CONTENTS

(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;

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