XXXXXX XXXXXX NATURAL GAS FUND, LP

This United States Natural Gas Fund, LP Authorized Participant Agreement (the “Agreement”), dated as of [ DATE], 2016, is entered into by and among United States Natural Gas Fund, LP (the “Fund”), United States Commodity Funds LLC, a Delaware limited liability company and the general partner of the Fund (the “General Partner”), on behalf of itself and as General Partner of United States Natural Gas Fund, LP, and [Insert name of Authorized Participant and type of company (Corporation, LLC, Inc., LLP)], a [state of incorporation/formation] (the “Authorized Participant”).

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”). Xxxxx Brothers Xxxxxxxx Co. (the “Administrator” or “Custodian”) and ALPS Distributors (the “Marketing Agent”) each serve as agents of the General Partner for all purposes of this Agreement, and all references to agreements, obligations or duties of the Administrator, Custodian or Marketing Agent herein shall be deemed references to agreements, obligations of duties of the General Partner acting through the relevant agent. As provided in the Partnership Agreement and described in the Fund’s prospectus (the “Prospectus”), as supplemented and amended from time to time, Shares of fractional undivided beneficial interest in and ownership of the limited partnership (the “Shares”) may be created or redeemed through the Marketing Agent by the Authorized Participant in aggregations of one hundred thousand (100,000) Shares (each aggregation, a “Creation Basket” or “Redemption Basket,” respectively; collectively, “Baskets”). Creation Baskets are offered only pursuant to the most recent registration statement of the Fund, 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 Participants 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 other than the indemnities provided in Section 9 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 Participant 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 Participant’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 Participant.

The Authorized Participant represents and warrants and covenants the following:

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

(b) Unless Section 2(c) applies, the Authorized Participant 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 Financial Industry Regulatory Authority (“FINRA”), or (ii) is exempt from being, or otherwise is not required to be, licensed as a broker-dealer or a member of FINRA, 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 Participant 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 Participant 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 FINRA (if it is a FINRA member) to the extent the foregoing relate to the Authorized Participant’s transactions in, and activities with respect to the Baskets. The Authorized Participant will not directly or indirectly offer or sell Shares in or from any state or jurisdiction where they may not lawfully be offered or sold.

(c) If the Authorized Participant is offering or selling Shares 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 FINRA as set forth in Section 2(b) above, the Authorized Participant 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 FINRA Conduct Rules, in each case to the extent the foregoing relate to the Authorized Participant’s transactions in, and activities with respect to the Baskets.

(d) The Authorized Participant has written policies and procedures reasonably designed to comply 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 Participant is subject to the requirements of the PATRIOT Act.

(e) The Authorized Participant has the capability to send and receive communications via an authenticated telecommunication facility to and from the General Partner and its agents, ALPS Distributors, Inc. and Xxxxx Brothers Xxxxxxxx & Co. The Authorized Participant shall confirm such capability to the satisfaction of the General Partner and the Marketing Agent by the end of the Business Day (as defined in Section 6) 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 Participant 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 Shares 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 Shares. The Authorized Participant 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 Participant 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 in Section 3). In addition to satisfying the prospectus-delivery and disclosure requirements of the 1933 Act, the Authorized Participant and any other participant in the distribution of the Shares purchased by the Authorized Participant also has the obligation to comply with applicable disclosure delivery requirements under the CEA. To the extent the Authorized Participant has distributed a Preliminary Prospectus to prospective investors, if the Authorized Participant has been notified by the General Partner of material changes made to that document as compared to the final Prospectus, the Authorized Participant shall give notice to any prospective investor who received the Preliminary Prospectus of such material change prior to consummating 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 Participant’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 Participant will comply with such procedures. The General Partner and Authorized Participant hereby consent to the use of recorded telephone lines.

(b) The Authorized Participant acknowledges and agrees it is acting for its own account or on behalf of another party (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 Participant. A form of Purchase/Redemption Order is attached hereto as Exhibit B.

Section 4. Fees.

In connection with each Order by an Authorized Participant to create or redeem one or more Baskets, the General Partner shall charge, and the Authorized Participant shall pay to the General Partner, the transaction fee (“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 as requested in writing from time to time thereafter, the Authorized Participant 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 Participant (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 Participant, the Authorized Participant 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 Participant may place an order with the Marketing Agent to create one or more Creation Baskets in accordance with this Agreement 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 NYSE Arca, ICE Futures 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 NYSE Arca, whichever is earlier, except in the case of an Authorized Participant’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 Participant. The day on which the Marketing Agent receives a valid Purchase Order is the Purchase Order Date. By placing a Purchase Order, an Authorized Participant agrees to (1) deposit Treasuries, cash, or a combination of Treasuries and cash with the Custodian of the Fund, and (2) if required by the General Partner in its sole discretion, enter into or arrange for a block trade, an exchange for physical or exchange for swap, or any other over-the-counter energy transaction (through itself or a designated acceptable broker) with the Fund for the purchase of a number and type of futures contracts at the closing settlement price for such contracts on the Purchase Order Date, as specified in the Purchase Order Form (see Exhibit B). 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 Fund’s investment objective and shall be purchased as a result of the Authorized Participant’s purchase of Shares.

Prior to the delivery of Baskets for a Purchase Order, the Authorized Participant 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/or 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 accepted as the number of Shares to be created under the Purchase Order is in proportion to the total number of Shares 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/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 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 Participant 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 Participant’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 cause DTC to credit the number of Baskets ordered to the Authorized Participant’s DTC account on the third Business Day following the Purchase Order Date, except in the case of an Authorized Participant’s initial order to purchase one or more Creation Baskets, when the Administrator will cause 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 Participant.

Section 7. Redemption Procedures.

On any Business Day, an Authorized Participant 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 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, an Authorized Participant agrees to (1) 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 (“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, as specified in the Redemption Order Form (see Exhibit B). 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 Fund’s investment objective and shall be sold as a result of the Authorized Participant’s sale of Shares. Prior to the delivery of the redemption distribution for a Redemption Order, the Authorized Participant 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 Participant 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 Shares to be redeemed under the Redemption Order is in proportion to the total number of Shares 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 shortly after 4:00 p.m. New York time on the Redemption Order Date.

The redemption distribution due from the Fund is delivered to the Authorized Participant on the Redemption Distribution Date if, by 3:00 PM New York time on such Redemption Distribution Date, 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 3:00 PM 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. 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 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 Redemption Distribution Date if the Authorized 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.

Section 8. Role of Authorized Participant.

(a) The Authorized Participant acknowledges that, for all purposes of this Agreement, the Authorized Participant 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.

(b) The Authorized Participant will, to the extent reasonably practicable, 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 Participant’s responsibilities under this Agreement; provided that the Authorized Participant shall be under no obligation to divulge or otherwise discuss any information that the Authorized Participant believes (i) is confidential or proprietary in nature or (ii) the disclosure of which to third parties would be prohibited.

(c) Notwithstanding the provisions of Section 8(b), the Authorized Participant will maintain records of all sales of Creation Baskets made by or through it and, upon reasonable request of the General Partner, except if prohibited by applicable law and subject to any privacy obligations or other obligations arising under federal or state securities laws it may have to its customers, will furnish the General Partner with the names and addresses of the Participants of such Creation Baskets and the number of Creation Baskets purchased if and to the extent that the General Partner has been requested to provide such information to the Commodities Futures Trading Commission, Securities Exchange Commission, Financial Industry Regulatory Authority, or Internal Revenue Service (“Fund Regulators”). For the avoidance of doubt, all such information provided by the Authorized Participant shall be Confidential Information (as defined in Section 18) and shall not be used for any purpose other than to satisfy requests of Fund Regulators.

(d) The Fund may from time to time be obligated to deliver prospectuses, proxy materials, annual or other reports of the Fund or other similar information (“Fund Documents”) to its limited partners. The Authorized Participant agrees (i) subject to any privacy obligations or other obligations arising under federal or state securities laws it may have to its customers, to reasonably assist the General Partner in ascertaining certain information regarding sales of Creation Baskets made by or through the Authorized Participant that is necessary for the Fund to comply with such obligations upon written request of the General Partner or (ii) in lieu thereof, and at the option of the Authorized Participant, the Authorized Participant may undertake to deliver Fund Documents to the Authorized Participant’s customers that custody Shares with the Authorized Participant, after receipt from the Fund of sufficient quantities of such Fund Documents to allow mailing thereof to such customers. The expenses associated with such transmissions shall be borne by the General Partner in accordance with usual custom and practice in respect of such communications. The General Partner agrees that the names, addresses and other information concerning the Authorized Participant’s customers are and shall remain the sole property of the Authorized Participant, and none of the General Partner, the Fund or any of their respective affiliates shall use such names, addresses or other information for any purposes except in connection with the performance of their duties and responsibilities hereunder and except to the extent necessary for the Fund to meet its regulatory requirements as set forth in Section 8(b) and in this Section 8(c) of the Agreement.

Section 9. Indemnification.

(a) Indemnification of Authorized Participant. The General Partner agrees to indemnify, defend and hold harmless the Authorized Participant, its partners, stockholders, members, directors, officers, employees, affiliates, agents and any person who controls such persons 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 (each a “GP Indemnified Person”), from and against any loss, damage, expense, liability or claim (including reasonable attorney fees and the reasonable cost of investigation) which the Authorized Participant 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 supplemented) or in a Prospectus (the term Prospectus for the purpose of this Section 9 being deemed to include the Prospectus and the Prospectus as amended or supplemented) or 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 Participant furnished in writing by or on behalf of the Authorized Participant 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, the Fund or their respective agents to perform when and as required, any agreement, obligation, duty or covenant contained herein;

(4)

the failure by the General Partner, the Fund or their respective agents to comply with applicable laws and the rules and regulations of any governmental entity or any self-regulatory organization to the extent the foregoing relates to transactions in, and activities with respect to Baskets; or

(5)

the Authorized Participant’s performance of its duties under this Agreement except in the case of this clause (5), for any loss, damage, expense, liability or claim resulting from the gross negligence or willful misconduct of the Authorized Participant.

In no case is the indemnity of the General Partner in favor of the Authorized Participant and such other persons as are specified in this Section 9(a) to be deemed to protect the Authorized Participant and such persons against any liability to the General Partner or the Fund to which the Authorized Participant 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 a GP Indemnified Person or any such person in respect of which indemnity may be sought against the General Partner pursuant to the foregoing paragraph, such GP Indemnified Person shall promptly notify the General Partner in writing of the institution of such Proceeding, provided, however, that the omission to so notify the General Partner shall not relieve the General Partner or the Fund from any liability which it may have to the GP Indemnified Person except to the extent that it has been materially prejudiced by such failure and has not otherwise learned of such Proceeding. The GP Indemnified Person shall have the right to employ its own counsel in any such case and the fees and expenses of such counsel shall be borne by the General Partner and the Fund 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 GP Indemnified Persons who are parties to such Proceeding) or for the expenses and fees incurred with respect to matters that are not indemnifiable in accordance with the preceding paragraph. A GP Indemnified Person shall give the General Partner reasonable prior notice of settlement of any Proceeding in respect of which indemnity may be sought against the General Partner pursuant to this Section 9(a), provided, however that the omission to so notify the General Partner shall not relieve the General Partner or the Fund from any liability which it may have to the GP Indemnified Person.

(b) The Authorized Participant 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 (each, an “AP Indemnified Person”), from and against any loss, damage, expense, liability or claim (including reasonable attorney fees and the reasonable cost of investigation) which the AP Indemnified Person may incur as a result of or in connection with 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 Participant 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 Participant will also indemnify each AP Indemnified Person from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which such AP Indemnified Person may incur as a result of or in connection with any actions of an AP Indemnified Person in accordance with any instructions by the Authorized Participant except in the case of any loss, damage, expense, liability or claim resulting from the gross negligence or willful misconduct of an AP Indemnified Person. In no case is the indemnity of the Authorized Participant in favor of each AP Indemnified Person to be deemed to protect the AP Indemnified Person and such persons against any liability to the Authorized Participant to which the AP Indemnified Person 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 an AP Indemnified Person, such AP Indemnified Person shall promptly notify the Authorized Participant in writing of the institution of such Proceeding; provided, however, that the omission to so notify the Authorized Participant shall not relieve the Authorized Participant from any liability which it may have to such AP Indemnified Person except to the extent that it has been materially prejudiced by such failure and has not otherwise learned of such Proceeding. The AP Indemnified Person or such person shall have the right to employ its own counsel and the fees and expenses of such counsel shall be borne by the Authorized Participant and paid as incurred (it being understood, however, that the Authorized Participant 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 AP Indemnified Persons who are parties to such Proceeding) or for the expenses and fees incurred with respect to matters that are not indemnifiable in accordance with the preceding paragraph. An AP Indemnified Person shall give the Authorized Participant reasonable prior notice of settlement of any Proceeding in respect of which indemnity may be sought against the Authorized participant pursuant to this Section 9(b), provided, however that the omission to so notify the General Partner shall not relieve the General Partner or the Fund from any liability which it may have to the GP Indemnified Person.

(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 Participant, 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 Participant 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 Shares. The General Partner and the Authorized Participant 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 Shares, or in connection with the Registration Statement or the Prospectus.

Section 10.

(a) Limitation of Liability.

None of the General Partner, the Authorized Participant, 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 Participant, 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 Participant 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 Participant. To the extent the General Partner or the Fund is required by law to pay any such tax or charge, the Authorized Participant 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 Participant 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 Participant by the General Partner in the event of a breach by the Authorized Participant 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 Participant represents, warrants and covenants that, (i) without the written consent of the General Partner, the Authorized Participant will not make, or permit any of its representatives to make, in connection with any sale or solicitation of a sale of Baskets any representations concerning the Shares or the General Partner, the Fund or any AP Indemnified Person other than representations consistent with (A) the then-current Prospectus of the Fund, (B) printed information approved by the General Partner as information supplemental to such Prospectus or (C) any promotional materials or sales literature furnished to the Authorized Participant by the General Partner, and (ii) the Authorized Participant 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 Participant in reasonable quantities upon request.

(b) The Authorized Participant agrees to comply with applicable prospectus and disclosure delivery requirements of the federal securities and commodities laws. In connection therewith, the Authorized Participant will provide, to the extent required, each prospective Participant, as required, with a copy of the Fund’s Prospectus.

(c) The Authorized Participant 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 Participant in Portable Document Format (“PDF”) via electronic mail to [_________________________] in lieu of delivering the Prospectus in paper form. The Authorized Participant may revoke the foregoing agreement at any time by delivering written notice to the General Partner and, whether or not such agreement is in effect, the Authorized Participant may, at any time, request reasonable quantities of the Prospectus, and any supplements or amendments thereto or recirculation thereof, in paper form from the General Partner or its agent, the Marketing Agent. The Authorized Participant 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 Participant, make available at no cost the software and technical assistance necessary to allow the Authorized Participant to access, view and print the PDF version of the Prospectus.

(d) For as long as this Agreement is effective, the Authorized Participant agrees to be identified as an authorized Participant of the Fund at the General Partner’s discretion (i) in the section of the Prospectus included within the Registration Statement entitled “Creation and Redemption of Shares,” and in any other section as may be required by the SEC and (ii) on the Fund’s website. Upon the termination of this Agreement, (i) during the period prior to when the General Partner qualifies and elects to file on Form S-3, the General Partner will remove such identification from the Prospectus in the amendment of the Registration Statement next occurring after the date of the termination of this Agreement and, during the period after when the General Partner qualifies and elects to file on Form S-3, the General Partner will promptly file a current report on Form 8-K indicating the withdrawal of the Authorized Participant as an authorized Participant of the Fund and (ii) the General Partner will promptly update the Fund’s website to remove any identification of the Authorized Participant as an authorized Participant of the Fund.

Section 14. Certain Covenants of the General Partner.

The General Partner, on its own behalf and on behalf of the Fund, covenants and agrees:

(a) to notify the Authorized Participant promptly of the happening of any event during the term of this Agreement which could require the making of any change in the Prospectus then being used so that the Prospectus would not include an untrue statement of material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they are made, not misleading, and, during such time, to prepare and deliver or otherwise make available, at the expense of the Fund, to the Authorized Participant copies of such amendments or supplements to such Prospectus as may be necessary to reflect any such change at such time and in such numbers as necessary to enable the Authorized Participant to comply with any obligation it may have to deliver such revised, supplemented or amended Prospectus to customers.

(b) to notify the Authorized Participant when a revised, supplemented, or amended Prospectus is available and to deliver or otherwise make available to the Authorized Participant copies of such revised, supplemented or amended Prospectus at such time and in such numbers as to enable the Authorized Participant to comply with any obligation it may have to deliver such revised, supplemented or amended Prospectus to customers, provided that as a general matter the General Partner will make such revised, supplemented or amended Prospectus available to the Authorized Participant on or before its effective date;

(c) to cause Xxxxxx Xxxxxxxx, LLP, accountants to the Fund, to deliver, at each time (i) the Registration Statement or the Prospectus is amended or supplemented by the filing of a post-effective amendment, (ii) a new Registration Statement is filed to register additional Baskets in reliance on Rule 429 of the 1933 Act, and (iii) there is financial information incorporated by reference into the Registration Statement or the Prospectus, letters dated such dates and addressed to the Authorized Participant, containing statements and information of the type ordinarily included in accountants’ letters to underwriters with respect to the financial statements and other financial information contained in or incorporated by reference into the Registration Statement and the Prospectus;

Each GP Indemnified Person, to the extent it is not a party to this Agreement, is a third-party beneficiary of this Agreement and may proceed directly against the General Partner, the Fund or their respective agents (including by bringing proceedings against the General Partner, the Fund or their respective agents in its own name) to enforce any obligation of the General Partner, the Fund or their agents under this Agreement which directly or indirectly benefits such GP Indemnified Person.

Section 17. Miscellaneous.

(a) Entire Agreement. This Agreement (including any schedules and exhibits attached hereto and thereto) contains all of the agreements among the parties hereto (and thereto) with respect to the transactions contemplated hereby (and thereby) and supersedes all prior agreements or understandings, whether written or oral, among the parties with respect thereto.

(b) Amendment and Modification. This Agreement may be amended, modified or supplemented only by a written instrument executed by all the parties.

(c) Successors and Assigns; Assignment. All the terms and provisions of this Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and permitted assigns. This Agreement shall not be assigned by any party without the prior written consent of the other parties and any assignment without such consent shall be null and void. Notwithstanding the foregoing, in the event that Authorized Participant files for protection under the United States Bankruptcy Code, the trustee of Authorized Participant's bankruptcy estate may assume this Agreement or any of its rights, duties and/or obligations hereunder or thereunder upon written notice to the Fund and the General Partner hereby consent to such assumption. In addition, Authorized Participant may assign the Agreement or any of its rights, duties and/or obligations hereunder or thereunder upon written notice to the Fund and the General Partner to (a) any Authorized Participant Affiliate; (b) in the case of any merger or sale of its stock or assets, to the successor in a merger of Authorized Participant or to any entity that acquires all or a substantial portion of its stock or assets, or (c) any service provider contracted by Authorized Participant to perform data processing, facilities management or other outsourced services on Authorized Participant’s behalf.

(d) Waiver of Compliance. Except as otherwise provided in this Agreement, any failure of any of the parties to comply with any obligation, covenant, agreement or condition herein may be waived by the party entitled to the benefits thereof only by a written instrument signed by the party granting such waiver, but any such waiver, or the failure to insist upon strict compliance with any obligation, covenant, agreement or condition herein, shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure or breach.

(e) Severability. The parties hereto desire that the provisions of this Agreement be enforced to the fullest extent permissible under the law and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, in the event that any provision of this Agreement would be held in any jurisdiction to be invalid, prohibited or unenforceable for any reason, such provision, as to such jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.

(f) Notices. All notices, waivers, or other communications pursuant to this Agreement shall be in writing and shall be deemed to be sufficient if delivered personally, by facsimile (and, if sent by facsimile, followed by delivery by nationally-recognized express courier), sent by nationally-recognized express courier or mailed by registered or certified mail (return receipt requested), postage prepaid, to the parties at the following addresses (or at such other address for a party as shall be specified by like notice):

In furtherance of the foregoing, the internal law of the State of New York will control the interpretation and construction of this Agreement, even if under such jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily or necessarily apply.

(2)

Each party irrevocably consents and agrees, for the benefit of the other parties, that any legal action, suit or proceeding against it with respect to its obligations, liabilities or any other matter arising out of or in connection with this Agreement or any related agreement may be brought in the courts of the State of New York and hereby irrevocably consents and submits to the non-exclusive jurisdiction of each such court in personam, generally and unconditionally with respect to any action, suit or proceeding for itself and in respect of its properties, assets and revenues. Each party irrevocably waives any immunity to jurisdiction to which it may otherwise be entitled or become entitled (including sovereign immunity, immunity to pre-judgment attachment and execution) in any legal suit, action or proceeding against it arising out of or based on this Agreement or any related agreement or the transactions contemplated hereby or thereby which is instituted in any court of the State of New York.

The provisions of this Section 17(g) shall survive any termination of this Agreement, in whole or in part.

(h) No Partnership. Nothing in this Agreement is intended to, or will be construed to constitute the General Partner or the Fund, on the one hand, and the Authorized Participant or any of its Affiliates, on the other hand, as partners or joint venturers; it being intended that the relationship between them will at all times be that of independent contractors.

(i) Interpretation. The article and section headings contained in this Agreement are solely for the purpose of reference, are not part of the agreement of the parties and shall not in any way affect the meaning or interpretation of this Agreement.

(j) No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rule of strict construction will be applied against any party.

(k) Counterparts; Facsimile Signatures. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument. Facsimile counterpart signatures to this Agreement shall be acceptable and binding.

(l) Other Usages. The following usages shall apply in interpreting this Agreement: (i) references to a governmental or quasigovernmental agency, authority or instrumentality shall also refer to a regulatory body that succeeds to the functions of such agency, authority or instrumentality; and (ii) “including” means “including, but not limited to.”

Section 18. Confidentiality.

(a) The General Partner, the Fund and the Authorized Participant shall 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 internal and external 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 or its customers 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:

(1)

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;

(2)

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;

(3)

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

(4)

is required to be disclosed by law or similar compulsion or in connection with any legal proceeding or request for information on behalf of a governmental authority or self-regulatory organization, 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.

(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.

IN WITNESS WHEREOF, the Authorized Participant and the General Partner have caused this Agreement to be executed by their duly authorized representatives as of the date first set forth above.

PROCEDURES FOR PROCESSING

PURCHASE ORDERS AND REDEMPTION ORDERS

United States Natural Gas Fund, LP. This Exhibit A to the Authorized Participant Agreement (the “Agreement”) supplements the Prospectus with respect to the procedures to be used by (i) the Transfer Agent and Marketing Agent in processing Purchase Orders and (ii) the Transfer Agent in processing Redemption Orders and, together with Purchase Orders, “Orders”. Capitalized terms, unless otherwise defined in this Annex II, have the meanings attributed to them in the Authorized Participant Agreement or the Prospectus.

An Authorized Participant is required to have signed the Authorized Participant Agreement. Upon acceptance of the Agreement and execution thereof by the Company and in connection with the initial Purchase Order submitted by the Authorized Participant, the Distributor will assign a unique PIN Number to each Authorized Person authorized to act for an Authorized Participant. This will allow an Authorized Participant through its Authorized Person(s) to place a Purchase Order or Redemption Order with respect to the purchase or redemption of Creation Units of Shares of the Fund.

TO PLACE AN ORDER FOR PURCHASE OR REDEMPTION OF CREATION UNITS

Placing an Order.

a. General. To the extent possible, Orders shall be submitted through the Internet (“Web Order Site” or “Electronic Interface”) as described in section 1.b. below. If the Electronic Interface is not available, Orders may be placed by telephone, as described in section 1.c. If a Purchase Order is not complete prior to the Order Cut-Off Time (as defined below), the Order will not be processed. Redemption Orders that are not completed prior to the Order Cut-Off Time will be processed on the next Business Day.

b. Using the Electronic Interface to Initiate the Order. An Authorized Person for the Authorized Participant will log in to the Electronic Interface prior to the cut-off time for placing Orders with the Fund (the “Order Cut-Off Time”) set forth in the particular Fund’s order form (“Order Form”) and enter the terms of the Order. An Order is not complete until it has been approved by both the Authorized Participant and the Marketing Agent under the terms of the Prospectus and the Agreement, in accordance with the procedures outlined below.

Orders submitted through the Electronic Interface must be in accordance with the terms of this Agreement, the Prospectus, the Web Order Site, the Electronic Interface User Agreement (the “Electronic Interface Agreement,” which must be separately entered into by the Authorized Participant) and the applicable Electronic Interface User Guide (or any successor documents). To the extent that any provision of this Agreement (including this Annex) is inconsistent with any provision of any Electronic Interface Agreement, the Electronic Interface Agreement shall control with respect to Distributor’s provision of the Web Order Site; provided, however, it is not the intention of the parties to otherwise modify the rights, duties and obligations of the parties under the Agreement, which shall remain in full force and effect until otherwise expressly modified or terminated in accordance with its terms. Notwithstanding the forgoing, the Authorized Participant acknowledges that references to the applicable Electronic Interface User Guide (or any successor documents) contained herein are for instructional purposes only, and such Electronic Interface User Guide (or any successor documents) does not contain any additional representations, warranties or obligations by the Fund, the Transfer Agent, the Marketing Agent or their respective agents.

A-1

c. Calling to Initiate the Order. In the event the Electronic Interface service is unavailable, an Authorized Person for the Authorized Participant may call the Marketing Agent’s telephone representative at the number listed on the Order Form prior to the Order Cut-Off Time to receive an Order Number, as described further below. The telephone call must be answered and concluded, and the Order must be complete, prior to the Order Cut-Off Time. Non-standard Orders generally must be arranged with the Fund in advance of Order placement. The Order Form (as may be revised from time to time) is incorporated into and made a part of this Agreement.

Upon verifying the authenticity of the caller (as determined by the use of the appropriate PIN Number) and the terms of the Order, the telephone representative will issue a unique order number (the “Order Number”) and record the terms of the Order in an electronic mail version of the Order Form. All Orders with respect to the purchase or redemption of Creation Units are required to be in writing (by email or, as provided below, by facsimile) and accompanied by the designated Order Number. During or following the call, the telephone representative will transmit the written Order Form to the Authorized Participant by electronic mail, indicating the approval of the Marketing Agent of the written Order Form.

To complete an Order, the Authorized Participant must respond to the telephone representative with its approval of the written Order Form by electronic mail prior to the Order Cut-Off Time. If the Authorized Participant detects an error or mistake in the written Order Form, it must return a corrected written Order Form to the telephone representative by electronic mail prior to the Order Cut-Off Time, indicating its approval of the corrected written Order Form. The telephone representative will review the corrected written Order Form and notify the Authorized Participant of the approval or rejection thereof by the Marketing Agent. The Order will be complete upon approval in writing by both the Authorized Participant and the Marketing Agent. If an Order is not complete prior to the Order Cut-Off Time, the Order will be invalid and will not be processed.

If the Authorized Participant is unable to send or receive electronic mail, it must inform the telephone representative when submitting the terms of its Order or as soon as such inability arises. Communication by facsimile may then be substituted for electronic mail in the steps described above, provided that each transmission is clearly marked with the time of transmission.

A-2

INCOMING TELEPHONE CALLS ARE QUEUED AND WILL BE HANDLED IN THE SEQUENCE RECEIVED. ACCORDINGLY, DO NOT HANG UP AND REDIAL. CALLS MUST BE CONCLUDED PRIOR TO THE ORDER CUT-OFF TIME. CALLS THAT ARE IN PROGRESS OR ARE UNANSWERED IN THE QUEUE AT OR AFTER THE ORDER CUT-OFF TIME WILL BE VERBALLY DENIED. INCOMING CALLS THAT ARE RECEIVED AFTER THE ORDER CUT-OFF TIME WILL NOT BE ANSWERED BY THE TELEPHONE REPRESENTATIVE. ALL TELEPHONE CALLS WILL BE RECORDED BY THE TELEPHONE REPRESENTATIVE.

NOTE THAT THE TELEPHONE CALL IN WHICH THE ORDER NUMBER IS ISSUED INITIATES THE ORDER PROCESS BUT DOES NOT ALONE CONSTITUTE THE ORDER. AN ORDER IS ONLY COMPLETED AND PROCESSED UPON WRITTEN APPROVAL BY BOTH THE AUTHORIZED PARTICIPANT AND THE MARKETING AGENT.

d. Settlement.

(i)

CNS Clearing Process. In general, the cash and or treasuries (collectively “cash”) as allowable pursuant to the Fund’s registration statement making up a Creation Unit must be delivered through the NSCC to a DTC account maintained at the Fund’s custodian on or before the Contractual Settlement Date (defined below). The “Contractual Settlement Date” is the earlier of: (i) the date upon which the Cash is delivered to the Fund; and (ii) trade date plus three (T +3) business days. Creation Units will be issued through the NSCC in accordance with the terms and conditions of the NSCC systems from time to time adopted and communicated to NSCC participants.

Any settlement outside the CNS Clearing Process may be subject to additional requirements and fees as discussed in the Prospectus.

(ii)

Outside the CNS Clearing Process.

	(a)	In general, the Cash making up a Creation Unit must be delivered to an account maintained at the applicable local Subcustodian on or before the International Contractual Settlement Date (defined below). The “International Contractual Settlement Date” will be the earlier of: (i) the date upon which the Cash is delivered to the Fund; and (ii) t trade date plus three (T +3) business days.

		Except as provided in the next two paragraphs, a Creation Unit will not be issued outside of the CNS Clearing Process until the transfer of good title to the Fund of the Cash and applicable fees have been completed. When the Subcustodian confirms to the Fund’s Custodian that the Cash has been delivered to the account of the relevant Subcustodian, the Custodian shall cause the delivery of the Creation Unit.

(b)

Cash redeems shall be settled outside the CNS process.

A-3

Further Information Regarding the Placement of Orders by the Internet.

Certain Acknowledgements. The Authorized Participant acknowledges and agrees (i) that the Fund, the General Partner, the Marketing Agent and their respective agents will review any Order placed through the Web Order Site manually before it is executed and that such manual review may result in a delay in execution of such Order; (ii) that during periods of heavy market activity or other times, it may be difficult to place Orders via the Web Order Site and the Authorized Participant may place Orders as otherwise set forth in Exhibit B; and (iii) that any transaction information, content, or data downloaded or otherwise obtained through the use of the Web Order Site are done at the Authorized Participant’s own discretion and risk.

EXCEPT AS OTHERWISE SPECIFICALLY PROVIDED IN THE ELECTRONIC INTERFACE AGREEMENT AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE AUTHORIZED PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE WEB ORDER SITE IS PROVIDED “AS IS,” “AS AVAILABLE” WITH ALL FAULTS AND WITHOUT ANY WARRANTY OF ANY KIND. SPECIFICALLY, WITHOUT LIMITING THE FOREGOING, ALL WARRANTIES, CONDITIONS, OTHER CONTRACTUAL TERMS, REPRESENTATIONS, INDEMNITIES AND GUARANTEES WITH RESPECT TO THE WEB ORDER SITE, WHETHER EXPRESS, IMPLIED OR STATUTORY, ARISING BY LAW, CUSTOM, PRIOR ORAL OR WRITTEN STATEMENTS BY THE FUND, THE GENERAL PARTNER, THE MARKETING AGENT OR THEIR RESPECTIVE AGENTS, AFFILIATES, LICENSORS OR OTHERWISE (INCLUDING, BUT NOT LIMITED TO AS TO TITLE, SATISFACTORY QUALITY, ACCURACY, COMPLETENESS, UNINTERRUPTED USE, NON-INFRINGEMENT, TIMELINESS, TRUTHFULNESS, SEQUENCE, COMPLETENESS, MERCHANTABILITY OR FITNESS FOR PARTICULAR PURPOSE AND ANY IMPLIED WARRANTIES, CONDITIONS AND OTHER CONTRACTUAL TERMS ARISING FROM TRADE USAGE, COURSE OF DEALING OR COURSE OF PERFORMANCE) ARE HEREBY OVERRIDDEN, EXCLUDED AND DISCLAIMED.

Election to Terminate Placing Orders by Internet. The Authorized Participant may elect at any time to discontinue placing Orders through the Web Order Site without providing notice under the Agreement.

Acknowledgment Regarding Telephone and Internet Transactions. During periods of heavy market activity or other times, the Authorized Participant acknowledges it may be difficult to reach the Fund by telephone or to transact business over the Internet via the Web Order Site. Technological irregularities may also make the use of the Internet and Web Order Site slow or unavailable at times. The Fund may terminate the receipt of redemption or exchange Orders by telephone or the Internet at any time, in which case the Authorized Participant may redeem or exchange Shares by communication through facsimile. All Orders must be complete, including written approval by the Authorized Participant and the Marketing Agent, prior to the Order Cut-Off Time.

EXHIBIT D

BBH Pricing Policies

Futures, Forwards, Swaps, Options and Treasuries

The pricing policies stated below are used for all BBH clients, including Mutual Fund Registered Investment Companies. These policies have been audited by numerous accounting firms during annual fund audits.

Futures

Futures traded on exchanges are valued using the closing settlement prices quoted on the relevant exchange and obtained from pricing sources, typically Bloomberg or Reuters.

Forward Currency Contracts

BBH obtains the WM Reuters London Close closing spot rates and the WM Reuters London Close forward point rates on a daily basis. 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.

Authorized Participant may make such copies of the Material as is reasonably necessary for Authorized Participant to use the System and shall reproduce Marketing Agent’s proprietary markings on any such copy. The foregoing shall not in any way be deemed to affect the copyright status of any of the Material which may be copyrighted and shall apply to all Material whether or not copyrighted.
