FORM OF UNITED STATES NATURAL GAS FUND, LP AUTHORIZED PURCHASER AGREEMENT

FORM OF

UNITED STATES NATURAL GAS FUND, LP

AUTHORIZED PURCHASER AGREEMENT

This United States Natural Gas Fund, LP Authorized Purchaser Agreement (the “Agreement”), dated as of ____________, is entered into by and between Victoria Bay Asset Management, LLC, a Delaware limited liability company and General Partner of United States Natural Gas Fund, LP (the “General Partner”), on behalf of itself and as General Partner of United States Natural Gas Fund, LP, and _________________, a [state] [type of business organization] (the “Authorized Purchaser”).

SUMMARY

The General Partner serves in its capacity as General Partner of United States Natural Gas Fund, LP (the “Fund”) pursuant to the Limited Partnership Agreement dated as of the day the first Creation Basket is sold and the proceeds are invested (substantially in the form attached hereto) between the General Partner and the Limited Partners of the Fund (the “Partnership Agreement”). As provided in the Partnership Agreement and described in the Fund’s prospectus (the “Prospectus”), Units of fractional undivided beneficial interest in and ownership of the limited partnership (the “Units”) may be created or redeemed through the Marketing Agent by the Authorized Purchaser in aggregations of one hundred thousand (100,000) Units (each aggregation, a “Creation Basket” or “Redemption Basket,” respectively; collectively, “Baskets”). Creation Baskets are offered only pursuant to the registration statement of the Fund on Form S-1, as amended (Registration No.: 333-137871), as declared effective by the Securities and Exchange Commission (the “SEC”) and as the same may be amended from time to time thereafter (collectively, the “Registration Statement”). Authorized Purchasers are the only persons that may place orders to create and redeem Creation Baskets or Redemption Baskets.

Capitalized terms used but not defined in this Agreement shall have the meanings assigned to such terms in the Prospectus. To the extent there is a conflict between any provision of this Agreement and the provisions of the Prospectus, the provisions of the Prospectus shall control.

To give effect to the foregoing premises and in consideration of the mutual covenants and agreements set forth below, the parties hereto agree as follows:

Section 1. Order Placement.

To place an order for the creation or redemption of one or more Baskets, an Authorized Purchaser must follow the procedures for creation and redemption referred to in Section 3 of this Agreement and attached to this Agreement as Exhibit A; provided, however, that in the case of an Authorized Purchaser’s initial order to purchase one or more Creation Baskets on the first day the Baskets are to be offered and sold, the procedures for creation will be as attached to this Agreement as Exhibit A-1.

Section 2. Status and Obligations of Authorized Purchaser.

The Authorized Purchaser represents and warrants and covenants the following:

(a) The Authorized Purchaser is a participant of the Depository Trust Company (“DTC”) (as such a participant, a “DTC Participant”). If the Authorized Purchaser ceases to be a DTC Participant, the Authorized Purchaser shall give immediate notice to the General Partner of such event, and this Agreement shall terminate immediately as of the date the Authorized Purchaser ceased to be a DTC Participant.

(b) Unless Section 2(c) applies, the Authorized Purchaser either (i) is registered as a broker-dealer under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is a member in good standing of the National Association of Securities Dealers, Inc. (the “NASD”), or (ii) is exempt from being, or otherwise is not required to be, licensed as a broker-dealer or a member of the NASD, and in either case is qualified to act as a broker or dealer in the states or other jurisdictions where the nature of its business so requires. The Authorized Purchaser will maintain any such registrations, qualifications and membership in good standing and in full force and effect throughout the term of this Agreement. The Authorized Purchaser will comply with all applicable federal law, the laws of the states or other jurisdictions concerned, and the rules and regulations promulgated thereunder, including, but not limited to those applicable to securities and commodities transactions, and with the Constitution, By-Laws and Conduct Rules of the NASD (if it is a NASD member), and is solely responsible for determining the application of any such laws or regulations in all cases at its own expense. The Authorized Purchaser will not directly or indirectly offer, sell or deliver Units in or from any state or jurisdiction where they may not lawfully be offered, sold and/or delivered.

(c) If the Authorized Purchaser is offering or selling Units in jurisdictions outside the several states, territories and possessions of the United States and is not otherwise required to be registered, qualified or a member of the NASD as set forth in Section 2(b) above, the Authorized Purchaser will (i) observe the applicable laws of the jurisdiction in which such offer and/or sale is made, (ii) comply with the full disclosure requirements of the Securities Act of 1933, as amended (the “1933 Act”) and the Commodities Exchange Act (the “CEA”), and the rules and regulations promulgated thereunder, and (iii) conduct its business in accordance with the spirit of the NASD Conduct Rules.

(d) The Authorized Purchaser is in compliance with the money laundering and related provisions of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (the “PATRIOT Act”), and the regulations promulgated thereunder, if the Authorized Purchaser is subject to the requirements of the PATRIOT Act.

(e) The Authorized Purchaser has the capability to send and receive communications via an authenticated telecommunication facility to and from the General Partner, ALPS Distributors, Inc. (the “Marketing Agent”) and Xxxxx Brothers Xxxxxxxx & Co., who shall act as both administrator (the “Administrator”) and custodian (the “Custodian”) for the Fund. The Authorized Purchaser shall confirm such capability to the satisfaction of the General Partner and the Marketing Agent by the end of the Business Day (as defined below) before placing its first order with the Marketing Agent (whether such order is to create or to redeem Baskets). If required by the Marketing Agent, the Administrator or the Custodian with respect to authorized telecommunications by telephonic facsimile, the Authorized Purchaser shall enter into a separate agreement with the Marketing Agent, the Administrator or the Custodian, as the case may be, indemnifying such party with respect to its communications by telephonic facsimile.

(f) Because new Baskets can be created and Units therein issued on an ongoing basis, at any point during the life of the partnership, a “distribution,” as such term is used in the 1933 Act, may be occurring with respect to resales of these Units. The Authorized Purchaser is cautioned that some of its activities may result in its being deemed a participant in a distribution in a manner that would render it a statutory underwriter and subject it to the prospectus-delivery and liability provisions of the 1933 Act. The Authorized Purchaser should review the “What is the Plan of Distribution?” portion of the Prospectus and consult with its own counsel in connection with entering into this Agreement and placing an Order (as defined below). In addition to satisfying the prospectus-delivery and disclosure requirements of the 1933 Act, the Authorized Purchaser and any other participant in the distribution of the Units purchased by the Authorized Purchaser also has the obligation to comply with the disclosure delivery requirements under the CEA, including, with respect to the CEA, the requirement that it provide an acknowledgement of receipt of the Prospectus (the “CEA Acknowledgement”) as set forth in Section 11, to the Fund, directly or through its agent, the Marketing Agent, prior to payment of the purchase price for any Creation Basket to the Fund. To the extent the Authorized Purchaser has distributed a Preliminary Prospectus to prospective investors, if there are material changes made to that document as compared to the final Prospectus, the Authorized Purchaser shall give notice to any prospective investor who received the Preliminary Prospectus of such material change prior to a sale.

Section 3. Orders.

(a) All orders to create or redeem Baskets shall be made in accordance with the terms of the Prospectus, this Agreement and the creation and redemption procedures attached hereto as Exhibit A (the “Procedures”), except in the case of an Authorized Purchaser’s initial order to purchase one or more Creation Baskets on the first day the Baskets are to be offered and sold which will be governed by the procedures set forth in Exhibit A-1. Each party will comply with such foregoing terms to the extent applicable to it. The General Partner may issue additional or other procedures from time to time relating to the manner of creating or redeeming Baskets and the Authorized Purchaser will comply with such procedures. The Authorized Purchaser hereby consents to the use of recorded telephone lines.

(b) The Authorized Purchaser acknowledges and agrees it is acting solely as principal and not on behalf of any party for which it is acting (whether such party is a customer or otherwise), and that each order to create a Basket (a “Purchase Order”) and each order to redeem a Basket (a “Redemption Order”, and each Purchase Order and Redemption Order, an “Order”) may not be withdrawn by the Authorized Purchaser. A form of Purchase/Redemption Order is attached hereto as Exhibit B.

(c) The General Partner acting by itself or through the Marketing Agent shall have the absolute right, but shall have no obligation, to reject any Purchase Order or Creation Basket Deposit (as defined in Section 6) (i) determined by the General Partner not to be in proper form; (ii) that the General Partner has determined would have adverse tax consequences to the Fund; (iii) the acceptance or receipt of which would, in the opinion of counsel to the General Partner, be unlawful; or (iv) if circumstances outside the control of the General Partner, the Marketing Agent or the Custodian make it for all practical purposes not feasible to process creations of Creation Baskets. None of the General Partner, the Marketing Agent or the Custodian shall be liable to any person by reason of the rejection of any Purchase Order or Creation Basket Deposit (as defined in Section 6).

(d) The General Partner acting by itself or through the Marketing Agent may, in its sole discretion, reject any Redemption Order (i) determined by the General Partner not to be in proper form (ii) the fulfillment of which its counsel advises may be illegal under applicable laws and regulations, or (iii) if the General Partner determines that circumstances outside the control of the General Partner, the Marketing Agent or the Custodian make it unlikely that the Units to be delivered under the Redemption Order will be delivered.

Section 4. Fees.

In connection with each Order by an Authorized Purchaser to create or redeem one or more Baskets, the General Partner shall charge, and the Authorized Purchaser shall pay to the General Partner, the Transaction Fee prescribed in the Prospectus applicable to such creation or redemption. The initial Transaction Fee shall be one thousand dollars ($1,000). The Transaction Fee may be adjusted from time to time as set forth in the Prospectus.

Section 5. Authorized Persons.

Concurrently with the execution of this Agreement and from time to time thereafter, the Authorized Purchaser shall deliver to the General Partner and the Marketing Agent, notarized and duly certified as appropriate by its secretary or other duly authorized official, a certificate in the form of Exhibit C setting forth the names and signatures of all persons authorized to give instructions relating to activity contemplated hereby or by any other notice, request or instruction given on behalf of the Authorized Purchaser (each, an “Authorized Person”). The General Partner or the Marketing Agent may accept and rely upon such certificate as conclusive evidence of the facts set forth therein and shall consider such certificate to be in full force and effect until the General Partner receives a superseding certificate bearing a subsequent date. Upon the termination or revocation of authority of any Authorized Person by the Authorized Purchaser, the Authorized Purchaser shall give immediate written notice of such fact to the General Partner and the Marketing Agent, and such notice shall be effective upon receipt by the General Partner.

Section 6. Creation Procedures.

On any Business Day, an Authorized Purchaser may place an order with the Marketing Agent to create one or more Creation Baskets in accordance with this Section 6 and the Procedures. For purposes of processing Purchase and Redemption Orders, a “Business Day” means any day other than a day when any of the American Stock Exchange, the New York Mercantile Exchange or the New York Stock Exchange is closed for regular trading. Purchase orders must be placed by 12:00 PM New York time or the close of regular trading on the American Stock Exchange, whichever is earlier, except in the case of an 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 AM New York Time on the day agreed to by the General Partner and the 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, cash, or a combination of Treasuries and cash with the Custodian of the Fund. Prior to the delivery of Baskets for a Purchase Order, the Authorized Purchaser must also have wired to the Custodian the non-refundable transaction fee due for the Purchase Order. “Treasuries” shall be any U.S. treasury security with two years or less remaining to maturity with an aggregate market value, as determined in the sole discretion of the Administrator using the valuation procedures set forth in Exhibit D, that together with any cash amount, will equal the purchase price of the Creation Basket being purchased.

The total deposit required to create each basket (“Creation Basket Deposit”) will be an amount of Treasuries and cash that is in the same proportion to the total assets of the Fund (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, 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 Treasuries 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.

The General Partner determines, directly in its sole discretion, or in consultation with the Administrator, the requirements for Treasuries and/or the amount of cash, including the maximum permitted remaining maturity of a Treasury and the 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. Unless otherwise determined by the General Partner, if Treasuries and cash are to be deposited, the amount of the cash deposit required will be the difference between (i) the aggregate market value of the Treasuries required to be included in a Creation Basket Deposit as of 4:00 PM New York time on the Purchase Order date and (ii) the total required deposit.

An Authorized Purchaser who places a Purchase Order is responsible for transferring to the Fund’s account with the Custodian the required amount of Treasuries and/or cash by the end of the third Business Day following the Purchase Order date, except in the case of an 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 the Creation Basket Deposit will be due by 12:00 PM New York time on the date the Purchase Order was accepted by the Marketing Agent. 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, except in the case of an Authorized Purchaser’s initial order to purchase one or more Creation Baskets, when the Administrator will direct DTC to credit the number of Baskets so ordered upon confirmation by the Custodian that the Creation Basket Deposit has been received by the Custodian. The expense and risk of delivery and ownership of Treasuries until such Treasuries have been received by the Custodian on behalf of the Fund shall be borne solely by the Authorized Purchaser.

Section 7. Redemption Procedures.

On any Business Day, an Authorized Purchaser may place an order with the Marketing Agent to redeem one or more Redemption Baskets in accordance with this Section 7 and the Procedures. Redemption Orders must be placed by 12:00 PM New York time or the close of regular trading on the American Stock Exchange, 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, an Authorized Purchaser agrees to deliver the Redemption Basket to be redeemed through DTC’s book-entry system to the Fund’s account with the Custodian not later than 3:00 PM 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 the Fund’s account at the Custodian the non-refundable Transaction Fee due for the Redemption Order.

The redemption distribution from the Fund consists of a transfer to the redeeming Authorized Purchaser of an amount of Treasuries and/or cash with a value that is in the same proportion to the total assets of the Fund (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, 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.

The redemption distribution due from the Fund is delivered to the Authorized Purchaser on the third Business Day following the Redemption Order date if, by 3:00 PM New York time on such third Business Day, the Fund’s DTC account has been credited with the Baskets to be redeemed. If the Fund’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 Fund 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 the Fund’s DTC account by 9:00 AM New York time on such next Business Day. Any further outstanding amount of the Redemption Order may be cancelled at the election of the General Partner. Pursuant to instruction from the General Partner, the Custodian may also deliver the redemption distribution notwithstanding that the Baskets to be redeemed are not credited to the Fund’s DTC account by 3:00 PM 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.

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 American Stock Exchange or the New York Mercantile Exchange is closed other than customary weekend or holiday closings, or trading on the American Stock Exchange or the New York Mercantile 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 or other assets of the Fund 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. 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.

Section 8. Role of Authorized Purchaser.

(a) The Authorized Purchaser acknowledges that, for all purposes of this Agreement, the Authorized Purchaser is and shall be deemed to be an independent contractor and has and shall have no authority to act as agent for the Fund, the Marketing Agent, the Administrator, the Custodian or the General Partner in any matter or in any respect, except as set forth in Section 2(f).

(b) The Authorized Purchaser will make itself and its employees available, upon request, during normal business hours to consult with the General Partner and the Marketing Agent concerning the performance of the Authorized Purchaser’s responsibilities under this Agreement.

(c) The Authorized Purchaser will maintain records of all sales of Creation Baskets made by or through it and will furnish copies of such records to the General Partner upon the reasonable request of the General Partner.

Section 9. Indemnification.

(a) Indemnification of Authorized Purchaser. The General Partner agrees to indemnify, defend and hold harmless the Authorized Purchaser, its partners, stockholders, members, directors, officers and employees and any Affiliate of the foregoing, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which the Authorized Purchaser or any such person may incur under the 1933 Act, the Exchange Act, the CEA, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon:

(1) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended or supplement) or in a Prospectus (the term Prospectus for the purpose of this Section 6 being deemed to include the Prospectus and the Prospectus as amended or supplemented), or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated in either such Registration Statement or such Prospectus or necessary to make the statements made therein not misleading, except insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information concerning the Authorized Purchaser furnished in writing by or on behalf of the Authorized Purchaser to the General Partner expressly for use in such Registration Statement;

(2) any untrue statement or alleged untrue statement of a material fact or breach by the General Partner of any representation or warranty contained in this Agreement;

(3) the failure by the General Partner to perform when and as required, any agreement or covenant contained herein;

(4) the Authorized Purchaser’s performance of its duties under this Agreement except in the case of this clause (4), for any loss, damage, expense, liability or claim resulting from the gross negligence or willful misconduct of the Authorized Purchaser.

In no case is the indemnity of the General Partner in favor of the Authorized Purchaser and such other persons as are specified in this Section 9(a) to be deemed to protect the Authorized Purchaser and such persons against any liability to the General Partner or the Fund to which the Authorized Purchaser would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under this Agreement.

If any action, suit or proceeding (each, a “Proceeding”) is brought against the Authorized Purchaser or any such person in respect of which indemnity may be sought against the General Partner pursuant to the foregoing paragraph, the Authorized Purchaser or such person shall promptly notify the General Partner in writing of the institution of such Proceeding and the General Partner shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify the General Partner shall not relieve the General Partner from any liability which it may have to the Authorized Purchaser or any such person except to the extent that it has been materially prejudiced by such failure and has not otherwise learned of such Proceeding. The Authorized Purchaser or such person shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Authorized Purchaser or of such person unless the employment of such counsel shall have been authorized in writing by the General Partner in connection with the defense of such Proceeding or the General Partner shall not have, within a reasonable period of time in light of the circumstances, employed counsel to have charge of the defense of such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with those available to the General Partner (in which case the General Partner shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the General Partner and paid as incurred (it being understood, however, that the General Partner shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding).

The General Partner shall not be liable for any settlement of any Proceeding effected without the General Partner’s written consent but if settled with the General Partner’s written consent, the General Partner agrees to indemnify and hold harmless the Authorized Purchaser and any such person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this paragraph, then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 Business Days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 Business Days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

(b) The Authorized Purchaser agrees to indemnify, defend and hold harmless each of the Fund, the General Partner and its partners, stockholders, members, directors, officers, employees and any person who controls the General Partner within the meaning of Section 15 of the 1933 Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which the General Partner any such person may incur under the 1933 Act, the Exchange Act, the CEA, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information furnished in writing by or on behalf of the Authorized Purchaser to the General Partner expressly for use in the Registration Statement (or in the Registration Statement as amended or supplemented by any post-effective amendment thereof) or in a Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such information required to be stated in such Registration Statement or such Prospectus or necessary to make such information not misleading.

The Authorized Purchaser will also indemnify the General Partner as stated above insofar as such loss, damage, expense, liability or claim arises out of or is based upon the Authorized Purchaser’s performance of its duties under this Agreement, except in the case of any loss, damage, expense, liability or claim resulting from the gross negligence or willful misconduct of the General Partner. In no case is the indemnity of the Authorized Purchaser in favor of the General Partner to be deemed to protect the General Partner and such persons against any liability to the Authorized Purchaser to which the General Partner would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under this Agreement.

If any Proceeding is brought against the General Partner or any person referred to in the preceding paragraph in respect of which indemnity may be sought against the Authorized Purchaser pursuant to the foregoing paragraph, the General Partner or such person shall promptly notify the Authorized Purchaser in writing of the institution of such Proceeding and the Authorized Purchaser shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify the Authorized Purchaser shall not relieve the Authorized Purchaser from any liability which it may have to the General Partner or any such person except to the extent that it has been materially prejudiced by such failure and has not otherwise learned of such Proceeding. The General Partner or such person shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the General Partner or such person unless the employment of such counsel shall have been authorized in writing by the Authorized Purchaser in connection with the defense of such Proceeding or the Authorized Purchaser shall not have, within a reasonable period of time in light of the circumstances, employed counsel to defend such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to or in conflict with those available to the Authorized Purchaser (in which case the Authorized Purchaser shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties, but the Authorized Purchaser may employ counsel and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of the Authorized Purchaser), in any of which events such fees and expenses shall be borne by the Authorized Purchaser and paid as incurred (it being understood, however, that the Authorized Purchaser shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding).

The Authorized Purchaser shall not be liable for any settlement of any such Proceeding effected without the written consent of the Authorized Purchaser but if settled with the written consent of the Authorized Purchaser, the Authorized Purchaser agrees to indemnify and hold harmless the General Partner and any such person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of the preceding paragraph, then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 Business Days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 Business Days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding.

(c) The indemnity agreements contained in this Section 9 and the covenants, warranties and representations of the General Partner contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the Authorized Purchaser, its partners, stockholders, members, directors, officers, employees and or any person (including each partner, stockholder, member, director, officer or employee of such person) who controls the Authorized Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the Exchange Act, or by or on behalf of each of the General Partner, the Fund, their partners, stockholders, members, directors, officers, employees or any person who controls the General Partner or the Fund within the meaning of Section 15 of the 1933 Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the initial issuance and delivery of the Units. The General Partner and the Authorized Purchaser agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the General Partner, against any of the General Partner’s officers or directors in connection with the issuance and sale of the Units, or in connection with the Registration Statement or the Prospectus.

Section 10.

(a) Limitation of Liability.

None of the General Partner, the Authorized Purchaser, the Marketing Agent, the Administrator, or the Custodian, shall be liable to each other or to any other person, including any party claiming by, through or on behalf of the Authorized Purchaser, for any losses, liabilities, damages, costs or expenses arising out of any mistake or error in data or other information provided to any of them by each other or any other person or out of any interruption or delay in the electronic means of communications used by them.

(b) Tax Liability.

The Authorized Purchaser shall be responsible for the payment of any transfer tax, sales or use tax, stamp tax, recording tax, value added tax and any other similar tax or government charge applicable to the creation or redemption of any Basket made pursuant to this Agreement, regardless of whether or not such tax or charge is imposed directly on the Authorized Purchaser. To the extent the General Partner or the Fund is required by law to pay any such tax or charge, the Authorized Purchaser agrees to promptly indemnify such party for any such payment, together with any applicable penalties, additions to tax or interest thereon.

Section 11. Acknowledgment.

The Authorized Purchaser acknowledges receipt of a copy of the Prospectus and represents that it has reviewed and understands such document.

Section 12. Effectiveness and Termination.

Upon the execution of this Agreement by the parties hereto, this Agreement shall become effective in this form as of the date first set forth above, and may be terminated at any time by any party upon thirty (30) days’ prior written notice to the other parties unless earlier terminated: (i) in accordance with Section 2(a); (ii) upon notice to the Authorized Purchaser by the General Partner in the event of a breach by the Authorized Purchaser of this Agreement or the procedures described or incorporated herein; or (iii) at such time as the Fund is terminated.

Section 13. Marketing Materials; Representations Regarding Baskets; Identification in Registration Statement.

(a) The Authorized Purchaser represents, warrants and covenants that (i), without the written consent of the General Partner, the Authorized Purchaser will not make, or permit any of its representatives to make, any representations concerning the Units or the General Partner, the Fund or any person indemnified by the Authorized Purchaser (the “AP Indemnified Person”) other than representations contained (A) in the then-current Prospectus of the Fund, (B) in printed information approved by the General Partner as information supplemental to such Prospectus or (C) in any promotional materials or sales literature furnished to the Authorized Purchaser by the General Partner, and (ii) the Authorized Purchaser will not furnish or cause to be furnished to any person or display or publish any information or material relating to the Baskets, any AP Indemnified Person or the Fund that is not consistent with the Fund’s then current Prospectus. Copies of the then-current Prospectus of the Fund and any such printed supplemental information will be supplied by the General Partner to the Authorized Purchaser in reasonable quantities upon request.

(b) The Authorized Purchaser agrees to comply with the prospectus and disclosure delivery requirements of the federal securities and commodities laws. In connection therewith, the Authorized Purchaser will provide each prospective purchaser with a copy of the Fund’s Prospectus and, to the extent required under the CEA or regulations promulgated thereunder, obtain (or require any participant in the distribution of Units in a Creation Basket the Authorized Purchaser has purchased to obtain) the CEA Acknowledgment from any such purchaser prior to receipt of payment from the purchaser. The Authorized Purchaser shall (or shall require any participant in distribution of such Units in a Creation Basket the Authorized Purchaser has purchased) maintain each such CEA Acknowledgement until the termination of this Agreement, and provide a copy to the General Partner upon reasonable request.

(c) The Authorized Purchaser hereby agrees that for the term of this Agreement the General Partner or its agent, the Marketing Agent, may deliver the then-current Prospectus, and any supplements or amendments thereto or recirculation thereof, to the Authorized Purchaser in Portable Document Format (“PDF”) via electronic mail or facsimile in lieu of delivering the Prospectus in paper form.

The Authorized Purchaser acknowledges that it has the capability to access, view, save and print material provided to it in PDF and that it will incur no appreciable extra costs by receiving the Prospectus in PDF instead of in paper form. The General Partner will, when requested by the Authorized Purchaser, make available at no cost the software and technical assistance necessary to allow the Authorized Purchaser to access, view and print the PDF version of the Prospectus.

Section 18. Confidentiality.

(a)

The General Partner and the Authorized Purchaser shall during the Term and for one (1) year thereafter maintain in confidence, use only for the purposes provided for in this Agreement, and not disclose to any third party, without first obtaining the other party’s consent in writing, any and all Confidential Information (as defined below) such party receives from the other party; provided, however, that either party may disclose Confidential Information received from the other party to those of its Representatives as may be necessary for such party to carry out its obligations under this Agreement.

“Confidential Information” shall mean all information or data of a party that is disclosed to or received by the other party, whether orally, visually or in writing, in any form, including, without limitation, information or data which relates to such party’s business or operations, research and development, marketing plans or activities, or actual or potential products.

(b)

Notwithstanding the provisions of this Agreement to the contrary, a party shall have no liability to the other party for the disclosure or use of any Confidential Information of the other party if the Confidential Information:

(i)

is known to such party at the time of disclosure other than as the result of a breach of this Section 18 by such party;

(ii)

has been or becomes publicly known, other than as the result of a breach of this Section 18 by such party, or has been or is publicly disclosed by the other party;

(iii)

is received by such party after the date of this Agreement from a third party (unless such third party breaches an obligation of confidentiality to the other party); or

(iv)

is required to be disclosed by law or similar compulsion or in connection with any legal proceeding, provided that such party shall promptly inform the other party in writing of such requirement and that such disclosure shall be limited to the extent so required and, except to the extent prohibited by law, such party shall reasonably cooperate with the other party (at the expense of the other party) in seeking a protective order or other suitable confidentiality protections.

(c)

The parties recognize and acknowledge that a breach or threatened breach by a party of the provisions of this Section 18 may cause irreparable and material loss and damage to the other party which cannot be adequately remedied at law and that, accordingly, in addition to, and not in lieu of, any damages or other remedy to which the non-breaching party may be entitled, the issuance of an injunction or other equitable remedy (without the requirement that a bond or other security be posted) is an appropriate remedy for the non-breaching party for any breach or threatened breach of the obligations set forth in this Section 18.

(d)

Each party agrees that it will use the same degree of care, but no less than a reasonable degree of care, in safeguarding the Confidential Information of the other party as it uses for its own Confidential Information of a similar nature. Each party shall promptly notify the other party in writing of any misuse, misappropriation or unauthorized disclosure of the Confidential Information of the other party that may come to such party’s attention.

(e)

Upon the termination of this Agreement, if requested in writing by the other party, each party shall, at such party’s option, promptly destroy or return to the other party all Confidential Information received from the other party, all copies and extracts of such Confidential Information and all documents or other media containing any such Confidential Information.

XXXXXX XXXXXX NATURAL GAS FUND, LP

CREATION AND REDEMPTION PROCEDURES

Scope of Procedures and Overview

These procedures (the “Procedures”) describe the processes by which one or more Baskets of United States Natural Gas Fund, LP Units (the “Units”) may be purchased by an Authorized Purchaser, or, once Units have been issued, redeemed by an Authorized Purchaser. Units may be created or redeemed only in blocks of 100,000 Units (each such block, a “Basket”).

For purposes of these Procedures, a “Business Day” is defined as any day other than a day on which the American Stock Exchange (“AMEX”), the New York Mercantile Exchange (“NYMEX”) or the New York Stock Exchange (“NYSE”) is closed for regular trading.

Baskets are issued pursuant to the Prospectus, which will be delivered by the Marketing Agent to each Authorized Purchaser prior to its execution of the Authorized Purchaser Agreement, and are issued and redeemed in accordance with the Authorized Purchaser Agreement. Baskets may be issued and redeemed on any Business Day by the Marketing Agent in exchange for cash and/or Treasuries, which the Custodian receives from Authorized Purchasers or transfers to Authorized Purchasers, in each case on behalf of the Fund.

Upon acceptance of the Authorized Purchaser Agreement, the Marketing Agent will assign a personal identification number (a “PIN number”) to each Authorized Person authorized to act for the Authorized Purchaser. This will allow the Authorized Purchaser through its Authorized Person(s) to place Purchase Order(s) or Redemption Order(s) for Baskets.

Important Notes:

· Any Order is subject to rejection by the General Partner or the Marketing Agent, as agent of the General Partner, for the reasons set forth in the Authorized Purchaser Agreement.

· All Orders are subject to the provisions of the Partnership Agreement, the Prospectus and the Authorized Purchaser Agreement relating to unclear or ambiguous instructions.

· The Authorized Purchaser, and each distributor offering and selling Units as part of the distribution of such Units, shall comply with the prospectus delivery and disclosure requirements of the 1933 Act as well as the analogous requirements under the CEA, including, the requirement that prospective investors provide an acknowledgement of receipt of such disclosure materials prior to the payment for any Units.

CREATION PROCESS

An Order to purchase one or more Baskets placed by an Authorized Purchaser with the Marketing Agent by 12:00 PM New York time or the close of regular trading on the AMEX, whichever is earlier (the “Order Cut-Off Time”) on a Business Day (such day, “CREATION T”) results in the transfer to the Authorized Purchaser’s account at The Depository Trust Company (“DTC”) of Baskets the Authorized Purchaser has purchased, in most instances, by 9:00 AM New York time on CREATION T+3:

CREATION PROCEDURES

1. By the Order Cut-Off Time (the earlier of the close of regular trading on the AMEX or 12:00 PM New York time), an Authorized Person of the Authorized Purchaser calls the Marketing Agent at (000) 000-0000 to notify such agent that the Authorized Purchaser wishes to place a Purchase Order to create an identified number of Baskets and to request that it be provided with an order number (an “Order Number”). The Authorized Person provides a PIN number as identification. The Marketing Agent provides the Authorized Purchaser with an Order Number for the Authorized Purchaser’s Purchase Order Form. The Authorized Purchaser then completes and faxes to the Marketing Agent the Purchase Order Form included as Exhibit B to the Authorized Purchaser Agreement. The Purchase Order Form must include the Authorized Person’s signature, the number of Baskets being purchased, and the Order Number.

2. If the Marketing Agent has not received the Purchase Order Form from the Authorized Purchaser within 15 minutes after the Marketing Agent receives the phone call from the Authorized Purchaser referenced in item (1) above, the Marketing Agent places a phone call to the Authorized Purchaser to enquire about the status of the Order. If the Authorized Purchaser does not fax the Purchase Order Form to the Marketing Agent within 15 minutes after the Marketing Agent’s phone call, the Authorized Purchaser’s Order is cancelled. The Marketing Agent will then notify the Authorized Purchaser that the Order has been cancelled via telephone call.

3. If the Marketing Agent has received the Authorized Purchaser’s Purchase Order Form on time in accordance with the preceding timing rules, then by 1:00 PM New York time the Marketing Agent returns to the Authorized Purchaser a copy of the Purchase Order Form submitted, marking it “Affirmed.”

4. Based on the Purchase Orders placed with it on CREATION T, the Marketing Agent sends a facsimile to the Transfer Agent indicating the total number of creation Units and total amount of cash and/or Treasuries for which the Marketing Agent will require an allocation into the custodial accounts of, respectively, the Authorized Purchaser and the Fund on CREATION T+3. If the Marketing Agent rejects a Purchase Order pursuant to the Authorized Purchaser Agreement after the foregoing messages are given to the Custodian, the Marketing Agent will notify the Transfer Agent of such rejection as soon as practicable but, in any event, by 1:30 PM New York time the same day, identifying the Authorized Purchaser whose Purchase Order was rejected and the amount of Units contained in the rejected Purchase Order. The Transfer Agent will address any such rejection notifications received after 1:30 PM New York time only on a best efforts basis.

REDEMPTION PROCESS

An order to redeem one or more Baskets placed by an Authorized Purchaser with the Marketing Agent by 12:00 PM New York time or the close of regular trading on the AMEX, whichever is earlier, on a Business Day (such day, “REDEMPTION T”) results in the following taking place by 3:00 p.m. New York time on REDEMPTION T+3:

· Transfer to the account at DTC and the subsequent cancellation of the relevant number of the Authorized Purchaser’s Baskets; and

2. If the Marketing Agent has not received the Redemption Order Form from the Authorized Purchaser within 15 minutes after the Marketing Agent receives the phone call from the Authorized Purchaser referenced in item (1) above, the Marketing Agent places a phone call to the Authorized Purchaser to enquire about the status of the Order. If the Authorized Purchaser does not fax the Redemption Order Form to the Marketing Agent within 15 minutes after the Marketing Agent’s phone call, the Authorized Purchaser’s Order is cancelled. The Marketing Agent will then notify the Authorized Purchaser that the Order has been cancelled via telephone call.

3. If the Marketing Agent has received the Authorized Purchaser’s Redemption Order Form on time in accordance with the preceding timing rules, then by 1:00 PM New York time the Marketing Agent returns to the Authorized Purchaser a copy of the Redemption Order Form submitted, marking it “Affirmed.” The Marketing Agent also indicates on the Redemption Order Form the amount of Treasuries and/or cash, if any, to be delivered in the Redemption Distribution, and provides details of the method of payment to be used for the Transaction Fee and the method of delivery of the Treasuries and/or cash portion, if any, of the Redemption Distribution.

The Transfer Agent will address any such rejection notifications received after 1:30 pm New York time only on a best efforts basis.

REDEMPTION T+3

1. By 3:00 PM New York time, the Authorized Purchaser delivers free to the relevant account at DTC the Baskets to be redeemed.

2. If the Custodian does not receive from a redeeming Authorized Purchaser all Units comprising the Baskets being redeemed by 3:00 PM New York time, (i) the Custodian will, only upon instruction from the General Partner, settle the Redemption Order to the extent of whole Baskets received from the Authorized Purchaser and (ii) the Marketing Agent will keep the redeeming Authorized Purchaser’s Redemption Order open until 9:00 AM New York time on the following Business Day (REDEMPTION T+4) as to the balance of the Redemption Order (such balance, the “Suspended Redemption Order”). For each day (whether or not a Business Day) the Redemption Order is held open, the Authorized Purchaser will be charged the greater of $300 or $30 times the number of Units included in the Suspended Redemption Order, as determined in the sole discretion of the Fund.

REDEMPTION T+4

The currency forward contract pricing model derives the differential in point rates to the expiration date of the forward and calculates its present value. The forward is valued at the net of the present value and the spot rate.

Swaps

Swaps and other similar derivative or contractual type instruments are valued at a price provided by a single broker or dealer, typically the counterparty. If no such price is available, the contract is valued at a price at which the counterparty to such contract would repurchase the instrument or terminate the contract.

Options

Option contracts on securities, currencies, indices, futures contracts, commodities and other instruments shall be valued at the last sale price on the exchange or market that is the Primary Market. If a contract did not trade on the Primary Market, it shall be valued at the last sale price on another exchange or market where it did trade. If there is no such sale price, the value shall be the most recent bid quotation.

Sale prices and bid quotations indicated above shall be supplied by a Pricing Service (Reuters, Bloomberg, IDC, etc.). If a Pricing Service is not able to provide such sale prices or bid quotations, the value shall be determined by taking the mean between the bid and the asked quotations provided by a single broker or dealer, unless the broker or dealer can only provide a bid quotation, in which case the value shall be such bid quotation.

Except as provided below, OTC currency options are valued by uploading the applicable implied volatility rates from Reuters or Bloomberg. Other inputs are either uploaded (interest rates, spots) or are specified when the ticker symbols are set up (expiration date, strike). OTC currency options are then priced by using the Xxxxxx-Xxxxxxxxx modified Black-Scholes formula, which adjusts for a constant yield versus a fixed dividend.

Except as provided below, OTC equity/index options are priced according to the contract specifications (days to expiration, current spot index level, interest rates, dividends, strike price) using the Black-Scholes pricing model, modified for dividends. The volatility input assumption is interpolated from the previous day’s price.

US Treasuries

BBH uses an evaluated bid supplied by IDC for treasury prices.
