    ADMINISTRATIVE
AGENCY AGREEMENT

    

    THIS ADMINISTRATIVE AGENCY AGREEMENT
(the “Agreement”)
is made as of March 5, 2007 by and among BROWN BROTHERS HARRIMAN &
CO., a limited partnership organized under the laws of the State of New
York (the “Administrator”), VICTORIA BAY ASSET MANAGEMENT,
LLC, a Delaware
limited liability company (the “General Partner”) and UNITED STATES NATURAL GAS FUND,
LP, a limited partnership organized under the laws of the State of
Delaware (the “Fund”).

    

    WITNESSETH:

    

    WHEREAS,
the Fund is a limited partnership that is registered as a commodity
pool;

    WHEREAS,
the General Partner has exclusive responsibility for the management and control
of the business and affairs of the Fund; and

    WHEREAS,
the Fund and the General Partner desire to retain the Administrator to render
certain services to the Fund and/or the General Partner, as the case may be, and
the Administrator is willing to render such services.

    NOW,
THEREFORE, in consideration of the premises and mutual covenants herein
contained, the parties hereto agree as follows:

    

    1.            Appointment of
Administrator.  The Fund and the General Partner hereby employ
and appoint the Administrator to act as administrative agent on the terms set
forth in this Agreement, and the Administrator accepts such
appointment.

    

    2.            Delivery of
Documents.  The Fund and the General Partner will on a
continuing basis provide the Administrator with:

    2.1           properly
certified or authenticated copies of resolutions of the General Partner’s Board
of Directors (including Mr. Nicholas D. Gerber) authorizing the appointment of
the Administrator as administrative agent of the Fund and approving this
Agreement;

    2.2           a
copy of the Fund’s most recent registration statement under the Securities Act
of 1933, as amended;

    2.3           copies

copy of the Fund’s valuation procedures;

    2.5           a
copy of the Fund’s Limited Partnership Agreement, as may be amended from time to

    2.6           a
copy of the General Partner’s First Amended and Restated Limited Liability
Company Agreement, as may be amended from time to time;

    2.7           any
other documents or resolutions (including, but not limited to directions or
resolutions of the General Partner’s Board of Directors, Management Directors,
and/or Audit Committee) which relate to or affect the Administrator’s
performance of its duties hereunder or which the Administrator may at any time
reasonably request; and

    2.8           copies
of any and all amendments or supplements to the foregoing.

    

    3.           
Duties as
Administrator.  Subject to the supervision and direction of the
General Partner’s Board of Directors, Management Directors and Audit Committee,
the Administrator will perform the administrative services described in Appendix
A hereto.  Additional services may be provided by the Administrator
upon the request of the Fund as mutually agreed from time to time.  In
performing its duties and obligations hereunder, the Administrator will act in
accordance with the General Partner’s instructions as defined in Section 5
(“Instructions”).  It is agreed and understood that the Administrator
shall not be responsible for the Fund’s or the General Partner’s compliance with
any applicable documents, laws or regulations, or for losses, costs or expenses
arising out of the Fund’s or the General Partner’s failure to comply with said
documents, laws or regulations or the Fund’s or the General Partner’s failure or
inability to correct any non-compliance therewith.  The Administrator
shall in no event be required to take any action, which is in contravention of
any applicable law, rule or regulation or any order or judgment of any court of
competent jurisdiction.

    

    3.1           Records.  The
Administrator will maintain and retain such records as required by the
Securities Exchange Act of 1934, as amended, the Rules of the American Stock
Exchange, 17 C.F.R 4.23, and other applicable federal securities laws and
created pursuant to the performance of the Administrator’s obligations under
this Agreement.  The Administrator will maintain such other records as
requested by the Fund or the General Partner and received by the
Administrator.  The Administrator shall not be responsible for the
accuracy and completeness of any records not created by the
Administrator.  The Administrator acknowledges that the records
maintained and preserved by the Administrator pursuant to this Agreement are the
property of the Fund and will be, at the Fund’s expense, surrendered promptly
upon reasonable request.  In performing its obligations under this
Section, the Administrator may utilize micrographic and electronic storage media
as well as independent third party storage facilities.

    4.            Duties of the
Fund and the General Partner.  The Fund and the General Partner
shall notify the Administrator promptly of any matter affecting the performance
by the Administrator of its services under this Agreement.  Where the
Administrator is providing fund accounting services pursuant to this Agreement,
the Fund and the General Partner shall promptly notify the Administrator as to
the accrual of liabilities of the Fund and of liabilities of the Fund not
appearing on the books of account kept by the Administrator, as well as to the
existence, status and proper treatment of reserves, if any, authorized by the
Fund or the General Partner.  The Fund and the General Partner agree
to provide such information to the Administrator as may be requested under the
banking and securities laws of the United States or other jurisdictions relating
to “Know Your Customer” and money laundering prevention rules and regulations
(collectively, the “KYC Requirements”).  For purposes of this
subsection, and in connection with all applicable KYC Requirements, the
Fund is the “client” or “customer” of the Administrator. The Fund and the General
Partner further represent that each will perform all obligations required under
applicable KYC Requirements with respect to the Fund’s “customers” (as defined
in the KYC Requirements) and that, because these customers do not constitute
“customers” or “clients” of the Administrator under such applicable rules and
regulations, the Administrator is under no such similar
obligations.

    

    
      	
              5.

            	
              Instructions.

            

    

    

    5.1           The
Administrator shall not be liable for, and shall be indemnified by the Fund
against any and all losses, costs, damages or expenses arising from or as a
result of, any action taken or omitted in reliance upon Instructions or upon any
other written notice, request, direction, instruction, certificate or other
instrument believed by it to be genuine and signed or authorized by the proper
party or parties.  A list of persons so authorized by the General
Partner (“Authorized Persons”) is attached hereto as Appendix B and upon which
the Administrator may rely until its receipt of notification to the contrary by
the General Partner.

    5.2           Instructions
shall include a written request, direction, instruction or certification signed
or initialed on behalf of the Fund by one or more Authorized
Persons.

    5.3           Telephonic
or other oral instructions or instructions given by telefax transmission may be
given by any one of the above Authorized Persons and will also be considered
Instructions if the Administrator believes them to have been given by a person
authorized to give such Instructions with respect to the transaction
involved.

    5.4           With
respect to telefax transmissions, the Fund and the General Partner hereby
acknowledge that (i) receipt of legible instructions cannot be assured, (ii) the
Administrator cannot verify that authorized signatures on telefax instructions
are original, and (iii) the Administrator shall not be responsible for losses or
expenses incurred through actions taken in reliance on such telefax
instructions.  The Fund and the General Partner agree that such
telefax instructions shall be conclusive evidence of the Fund’s/General
Partner’s Instruction to the Administrator to act or to omit to
act.

     

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

     

    5.5           Instructions
given orally will not be confirmed in writing and the lack of such confirmation
shall in no way affect any action taken by the Administrator in reliance upon
such oral Instructions.  The Fund and the General Partner authorize
the Administrator to tape record any and all telephonic or other oral
Instructions given to the Administrator by or on behalf of the Fund (including
any of the Fund’s or the General Partner’s officers, directors, trustees,
employees or agents or any investment manager or adviser or person or entity
with similar responsibilities which is authorized to give Instructions on behalf
of the Fund to the Administrator.)

    

    6.            Expenses and
Compensation.  For the services to be rendered and the
facilities to be furnished by the Administrator as provided for in this
Agreement, the Fund shall pay the Administrator rendered pursuant to this
Agreement a fee based on such fee schedule as may from time to time be agreed
upon in writing among the General Partner, Fund and the
Administrator.  Additional services performed by the Administrator as
requested by the Fund shall be subject to additional fees as mutually agreed
from time to time.  In addition to any such fees, the Administrator
shall bill the Fund separately for any out-of-pocket disbursements of the
Administrator based on an out-of-pocket disbursement schedule as may from time
to time be agreed upon in writing among the General Partner, the Fund and the
Administrator.  The initial fee schedule and out of pocket
disbursement schedule are attached as Appendix D to this
Agreement.  The foregoing fees and disbursements shall be billed to
the Fund by the Administrator and shall be paid promptly by wire transfer or
other appropriate means to the Administrator.

     

    7.            Standard of
Care.  The Administrator
shall be held to the exercise of reasonable care and diligence in carrying out
the provisions of this Agreement, provided that the Administrator shall not
thereby be required to take any action which is in contravention of any
applicable law, rule or regulation or any order or judgment of any court of
competent jurisdiction.

    

    8.            General
Limitations on Liability.  The Administrator shall incur no
liability with respect to any telecommunications, equipment or power failures,
or any failures to perform or delays in performance by postal or courier
services or third-party information providers (including, without limitation
those listed on Appendix C).

    

    
      8.1       
The
Administrator shall also incur no liability under this Agreement if the
Administrator or any agent or entity utilized by the Administrator shall be
prevented, forbidden or delayed from performing, or omits to perform, any act or
thing which this Agreement provides shall be performed or omitted to be
performed, by reason of causes or events beyond its control, including but not
limited to:

    

     

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

     

    
      8.1.1
any
Sovereign Event.  A “Sovereign Event” shall mean any nationalization;
expropriation; devaluation; revaluation; confiscation; seizure; cancellation;
destruction; strike; act of war, terrorism, insurrection or revolution; or any
other act or event beyond the Administrator’s control;

    

    
      8.1.2
any
provision of any present or future law, regulation or order of the United States
or any state thereof, or of any foreign country or political subdivision
thereof, or of any securities depository or clearing agency;
and

    

    
      8.1.3
any
provision of any order or judgment of any court of competent
jurisdiction.

    

    

    
      
        8.2        
The
Administrator shall not be held accountable or liable for any losses, damages or
expenses the General Partner, the Fund or any unitholder or former unitholder of
the Fund or any other person may suffer or incur arising from acts, omissions,
errors or delays of the Administrator in the performance of its obligations and
duties as provided in Section 3 hereof, including without limitation any error
of judgment or mistake of law, except a loss, damage or expense directly
resulting from the Administrator’s willful malfeasance, bad faith or negligence
in the performance of such Administrator’s obligations and
duties.

      

    

    

    
      	
              9.

            	
              Specific
      Limitations on Liability. In addition to,
      and without limiting the application of the general limitations on
      liability contained in Section 8, above, the following specific
      limitations on the Administrator’s liability shall apply to the particular
      administrative services set forth on Appendix A
  hereto.

            

    

    

    9.1           Liability for
Fund Accounting Services.   Without limiting the provisions in
Section 8 hereof, the Administrator’s liability for acts, omissions, errors or
delays relating to its fund accounting obligations and duties shall be limited
to the amount of any expenses associated with a required recalculation of net
asset value per unit (“NAV”) or any direct damages suffered by unitholders in
connection with such recalculation.  The Administrator’s liability or
accountability for such acts, omissions, errors or delays shall be further
subject to clauses 9.1.1 through 9.1.4 below.

     

    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

     

    
      9.1.1
The
parties hereto acknowledge that the Administrator’s causing an error or delay in
the determination of NAV may, but does not in and of itself, constitute
negligence or reckless or willful misconduct.  The parties further
acknowledge that in accordance with industry practice the liability of the
Administrator for fund accounting services shall accrue and the recalculation of
NAV shall be performed in accordance with this Section 9.1 only with regard to
errors in the calculation of the NAV that are (i) greater than or equal to $.01
per unit of the Fund and (ii) greater than or equal to 1⁄2% of the total net
assets of the Fund.

    

    
      
        9.1.2
In
no event shall the Administrator be liable or responsible to the General
Partner, the Fund, any present or former unitholder of the Fund, or any other
person for any error or delay that continued or was undetected after the date of
an audit performed by the certified public accountants employed by or on behalf
of the Fund if, in the exercise of reasonable care in accordance with generally
accepted accounting standards, such accountants should have become aware of such
error or delay in the course of performing such audit.

      

    

    
      
        9.1.3
The
Administrator shall not be held accountable or liable to the General Partner,
the Fund, any unitholder or former unitholder thereof or any other person for
any delays or losses, damages or expenses any of them may suffer or incur
resulting from (i) the Administrator’s usage of a third party service provider
for the purpose of storing records delivered to the Administrator by or on
behalf of the Fund and which the Administrator did not create in the performance
of its obligations hereunder; (ii) the Administrator’s failure to receive timely
and suitable notification concerning quotations or corporate actions relating to
or affecting portfolio securities of the Fund; or (iii) any errors in the
computation of NAV based upon or arising out of quotations or information as to
corporate actions if received by the Administrator either (a) from a source
which the Administrator was authorized to rely upon (including those sources
listed on Appendix C), or (b) from a source which in the Administrator’s
reasonable judgment was as reliable a source for such quotations or information
as such authorized sources; or (iv) any errors in the computation of NAV as a
result of relevant information known to the General Partner, the Fund, a futures
commission merchant, securities brokers or dealers, or any of the Fund’s other
service providers including futures commission merchants in contract with the
Fund, which would impact the calculation of NAV, but was not communicated to the
Administrator.  To the extent that Fund assets are not in the custody
of the Administrator, the Administrator may conclusively rely on any reporting
in connection with such assets provided to the Administrator by a third party on
behalf of the Fund, including, without limitation any futures commission
merchant.

      

       

      
        
          
          

        

        
          6

          
            

          

        

        
          
          

        

      

       

    

    
      
        9.1.4
In
the event of any error or delay in the determination of such NAV for which the
Administrator may be liable, the General Partner, the Fund and the Administrator
will consult and make good faith efforts to reach agreement on what actions
should be taken in order to mitigate any loss suffered by the Fund or its
present or former unitholders, in order that the Administrator’s exposure to
liability shall be reduced to the extent possible after taking into account all
relevant factors and alternatives.  It is understood that in
attempting to reach agreement on the actions to be taken or the amount of the
loss which should appropriately be borne by the Administrator, the General
Partner, the Fund and the Administrator will consider such relevant factors as
the amount of the loss involved, the Fund’s/General Partner’s desire to avoid
loss of unitholder goodwill, the fact that other
persons or entities could have been reasonably expected to have detected the
error sooner than the time it was actually discovered, the appropriateness of
limiting or eliminating the benefit which unitholders or former unitholders
might have obtained by reason of the error, and the possibility that other
parties providing services to the Fund might be induced to absorb a portion of
the loss incurred.

      

    

    

    
      	
              10.

            	
              Indemnification.

            

    

    10.1             The
General Partner and the Fund hereby agree to indemnify and hold harmless the
Administrator, its partners, stockholders, members, directors, officers and
employees and any subsidiary or affiliate of the foregoing (“Affiliate”), and
the successors and assigns of all of the foregoing persons, against any and all
losses, claims, damages, liabilities or expenses (including reasonable counsel
fees and expenses) resulting from any act, omission, error or delay or any
claim, demand, action or suit, in connection with or arising out of performance
of its obligations and duties under this Agreement, not resulting from the
willful malfeasance, bad faith or negligence of the Administrator in the
performance of such obligations and duties.  The provisions of this
Section 10 shall survive the termination of this Agreement.

    

    10.1.1     If
any action, suit or proceeding (each, a “Proceeding”) is brought against the
Administrator or any such person in respect of which indemnity may be sought
against the General Partner pursuant to the foregoing subsection, the
Administrator 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 release the General Partner from any liability which it may have to
the Administrator 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 Administrator 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 Administrator 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).

    10.1.2     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 Administrator 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 subsection, 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 (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
(each a “Business Day”)), 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.

    10.2             Subject
to Sections 7, 8 and 9 of this Agreement, the Administrator agrees to indemnify
and hold harmless the General Partner and the Fund, 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, against any and
all losses, claims, damages, liabilities or expenses (including reasonable
counsel fees and expenses) resulting from any act, omission, error or delay or
any claim, demand, action or suit, in connection with or arising out of
performance of its obligations and duties under this Agreement, resulting from
the willful malfeasance, bad faith or negligence of the Administrator in the
performance of such obligations and duties.  The provisions of this
Section 10 shall survive the termination of this Agreement.

    10.2.1     If
any Proceeding is brought against the General Partner or any such person in
respect of which indemnity may be sought against the Administrator pursuant to
the foregoing subsection, the General Partner or such person shall promptly
notify the Administrator in writing of the institution of such Proceeding and
the Administrator 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 Administrator shall not relieve the Administrator 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 of such person
unless the employment of such counsel shall have been authorized in writing by
the Administrator in connection with the defense of such Proceeding or the
Administrator 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 Administrator (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 Administrator and paid as
incurred (it being understood, however, that the Administrator 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).

    10.2.2     The
Administrator shall not be liable for any settlement of any Proceeding effected
without the Administrator’s written consent but if settled with the
Administrator’s written consent, the Administrator 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 this subsection, 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
