Re: Smith Barney Potomac Futures Fund L.P.
- ---------------------------------------

Gentlemen:

     Smith Barney Potomac Futures Fund L.P. (the "Partnership") was organized as
a limited  partnership  under the New York Revised Uniform  Limited  Partnership
Act, as amended (the "Partnership  Act") for the purpose of speculative  trading
in commodity  interests including futures contracts,  options,  spot and forward
contracts.  Smith Barney Futures Management LLC ("SBFM" or the "General Partner"
has been elected general partner of the Partnership and SFG Global  Investments,
Inc. has withdrawn as general  partner of the  Partnership,  effective as of the
date hereof.  You,  the  Partnership  and SBFM entered into an agency  agreement
dated April 22, 1997 (the "Initial Agency Agreement"). This Amended and Restated
Agency  Agreement (the  "Agreement")  supersedes the Initial Agency Agreement in
all respects.

     The General  Partner  desires to raise capital for the  Partnership  by the
sale of units of limited  partnership  interest therein (the "Units") to certain
qualified  investors  pursuant  to Rule 506 of  Regulation  D ("Reg.  D")  under
section 4(2) of the Securities Act of 1933, as amended (the  "Securities  Act").
The General Partner,  the  Partnership,  the business of the Partnership and the
Units are described in a Private  Placement  Offering  Memorandum and Disclosure
Document dated August 24, 2000, prepared by the General Partner. As used in this
Agreement, "Memorandum" refers to that Private Placement Offering Memorandum and
Disclosure Document, including the appendices thereto, unless such memorandum or
appendices  have been  supplemented  or  amended,  in which  case the term shall
refer,  from and after the time the supplement or amendment is delivered to you,
to the memorandum and appendices as so amended and  supplemented.  The commodity
trading  advisor to the Partnership is currently  Campbell & Company,  Inc. (the
"Advisor").

     The  subscribers  for Units will be required  to execute  the  Subscription
Agreement, a copy of which is attached as an appendix to the Memorandum,  and to
tender or cause to be tendered  for each Unit  subscribed  cash in the amount of
the Net Asset  Value  per Unit on the date of  purchase.  Subscribers  for Units
whose  Subscription  Agreements are accepted by the General  Partner will become
limited partners of the Partnership (the "Limited  Partners") upon the execution
by the  General  Partner as  attorney-in-fact  for each such  subscriber  of the
Second Amended and Restated Limited  Partnership  Agreement,  a copy of which is
attached as an appendix to the Memorandum (the "Partnership Agreement"),  and at
the time such  subscribers'  names are  entered in the books and  records of the
Partnership.

Section 1. Appointment of Agent.

     On the basis of the representations,  warranties and covenants contained in
this Agreement, but subject to the terms and conditions set forth in it, you are
hereby  appointed the  exclusive  agent of the  Partnership  during the offering
period specified in this Section, for the purpose of finding subscribers for the
Units for the account and risk of the  Partnership  through a private  offering.
The offering period will continue until the General  Partner  terminates it (the
"Continuous  Offering").  Units or  partial  Units sold  during  the  Continuous
Offering  will be sold at Net  Asset  Value  per Unit as of the last day of each
month,  provided  that the General  Partner may determine to offer no Units in a
particular  month.  Subject to the  performance by the General Partner of all of
its obligations to be performed under this Agreement and to the completeness and
accuracy of all material  representations  and warranties of the General Partner
contained  in this  Agreement,  you hereby  accept  such agency and agree on the
terms and conditions set forth in this Agreement to use your best efforts during
the Continuous  Offering to find  subscribers  for the Units.  Your agency under
this  Agreement,  which is  coupled  with an  interest  and,  therefore,  is not
terminable by the General Partner without your  permission,  will continue until
the termination of the Continuous Offering.


Section 2.  Representations  and Warranties of the  Partnership  and the General
Partner.

     (a) The Partnership and the General Partner jointly and severally represent
and warrant to you, for your benefit,  and for the benefit of the  purchasers of
the Units that:

     (i) They will deliver to you such number of copies of the Memorandum as you
may  reasonably  request,  regardless of whether the Units are offered solely to
"accredited  investors"  as defined in Rule 501(a) of Reg. D. They will not make
any amendment or supplement to the  Memorandum  until they have given you a copy
thereof and  reasonable  notice of the same, and no such amendment or supplement
will be made if you reasonably object thereto.

     (ii)  The  Memorandum  complies  with  Rule  502(b)(2)  of  Reg.  D and the
information  to be made  available  or  furnished  to each  purchaser  of a Unit
pursuant to Section 5(f) hereof or otherwise  will be  sufficient to comply with
Rule 502(b)(2)(iv) and 502(b)(2)(v) of Reg. D.

     (iii) The  Memorandum  will not contain any untrue  statement of a material
fact or omit to state a material fact  necessary in order to make the statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.

     (iv) All action required under the Partnership Agreement or otherwise to be
taken by the General Partner before the  subscription  for and sale of the Units
to subscribers  therefor has been taken or before the Monthly  Closing dates, as
defined in Section 4 hereof,  will have been taken,  and upon (i) payment of the
consideration therefor specified in the Subscription Agreement,  (ii) acceptance
by the General Partner of each subscriber acceptable to the General Partner, and
(iii) the  payment of any  required  filing  fee,  the  subscribers  will become
Limited  Partners  of the  Partnership  entitled  to all the  rights of  Limited
Partners under the  Partnership  Agreement and the  Partnership  Act. The Units,
when sold and paid for as contemplated by the Memorandum, will represent validly
authorized and duly issued limited partnership  interests in the Partnership and
will conform to all statements  relating  thereto  contained in the  Memorandum,
including the Partnership Agreement.

     (v) The  Partnership is a limited  partnership  duly and validly  organized
pursuant to the  Partnership  Agreement and the laws of New York, and is validly
existing  under,  and  subject  to,  the laws of New York  with  full  power and
authority to conduct the business in which it proposes to engage as described in
the  Memorandum.  A  Limited  Partner  will have no  liability  in excess of his
capital  contribution  and his share of  Partnership  assets  and  undistributed
profits except as set forth in Section 7(f) of the Partnership  Agreement and in
the Partnership Act.

     (vi) There is no action,  suit,  litigation or proceeding  before or by any
court or governmental  agency,  federal,  state or local,  pending or threatened
against or  affecting  or  involving  the  property  or  business of the General
Partner, or the business of the Partnership, that would materially and adversely
affect the  condition  (financial  or  otherwise),  business or prospects of the
General Partner or the Partnership.

     (vii) Neither the Partnership,  the General Partner nor any person directly
or indirectly  affiliated  with any of them has,  either  directly or through an
agent,  sold or offered for sale or solicited offers to subscribe for or buy, or
approached  potential  investors for or otherwise  negotiated in respect of, the
Units except for the activities of the General Partner in approaching  potential
investors  undertaken in cooperation  with you after advance  consultation  with
you; and neither the Partnership, the General Partner nor any person directly or
indirectly affiliated with any of them has, either directly or through an agent,
participated  in the  organization  or  management of any  partnership  or other
entity, or has engaged in any other activity, in a manner or under circumstances
that would  jeopardize  the status of the  offering  of the Units as an exempted
transaction  under the Securities Act or under the laws of any state in which it
is represented by the General Partner that the offering may be made.


     (viii) This  Agreement  and the  Partnership  Agreement  have been duly and
validly  authorized,  executed  and  delivered  by and on behalf of the  General
Partner and  constitute  valid and  binding  agreements  of the General  Partner
enforceable in accordance with their terms.  This Agreement and the Subscription
Agreements  have  been or will be duly  and  validly  authorized,  executed  and
delivered by and on behalf of the  Partnership and constitute or will constitute
valid and binding  agreements of the Partnership  enforceable in accordance with
their terms.

     (ix)  The  execution  and  delivery  of this  Agreement,  the  Subscription
Agreements  and  the  Partnership   Agreement,   and  the  consummation  of  the
transactions  contemplated  in  this  Agreement  and in the  Memorandum,  do not
conflict  with and will not  constitute  a breach  of,  or  default  under,  the
certificate of formation or limited  liability  company agreement of the General
Partner or any agreement or  instrument by which it is bound by any order,  rule
or  regulation  applicable  to it of any  court  or  any  governmental  body  or
administrative agency having jurisdiction over it.

     (x) A separate  escrow  account has been opened at European  American Bank,
New York,  New York (the "Escrow  Agent") and will be  maintained  for all funds
received from subscribers for Units. All payments received from persons desiring
to purchase Units will be deposited in such account and held in accordance  with
the terms of the Escrow Agreement entered into with the Escrow Agent.

Section 3. Your Representations and Warranties.


     You represent and warrant to and for the benefit of the Partnership and the
General Partner that:

     (a)  You  will  not  offer  or  sell  the  Units  by any  form  of  general
solicitation or general advertising within the meaning of Rule 502(c) of Reg. D.

     (b) Where required by applicable state law or regulation, you will initiate
contact with a prospective  offeree only after  determining that the suitability
and  sophistication  standards  described  in the  Memorandum  are  likely to be
satisfied with respect to such prospective  offeree and, where applicable,  only
after having obtained an executed Purchaser Representative Questionnaire.

     (c) You will not offer the Units  for sale to,  or  solicit  any  offers to
subscribe  for the  Units  from,  any  offeree  who  resides  in a  state  whose
securities or "blue sky" laws require offerees to meet specified  qualifications
unless such offeree meets such  qualifications or which laws require offerees to
receive  disclosure  documents until you have delivered (or directed the General
Partner to deliver) the  Memorandum,  the Partnership  Agreement,  and any other
agreement or document that may be attached as an exhibit or appendix referred to
in and distributed with the Memorandum or any other information  provided by the
General Partner which is required to be delivered to purchasers pursuant to Rule
502(b)(2) of Reg. D to such offeree,  and within a reasonable  time prior to the
Monthly  Closing you shall deliver (or cause the General Partner to deliver) all
such documents to all persons who are to purchase the Units,  to the extent they
have not theretofore  received such documents.  In connection with the offering,
you will not represent to any person acquiring Units any material facts relating
to the offering  unless such facts are contained in the  Memorandum or have been
provided to you in writing by the General Partner.

     (d) You will make offers to sell Units to, or solicit  offers to  subscribe
for Units from,  persons in only those states or other  jurisdictions  where the
General  Partner has either  qualified  or  registered  the offering for sale or
where  the  General   Partner  has  determined   that  an  exemption  from  such
qualification  or registration  is available under the applicable  securities or
"blue sky"  statutes  of such states or other  jurisdictions.  You will not sell
Units to any person unless, immediately before making such sales, you reasonably
believe such person (i) would be able to represent that such person is acquiring
the Units for such person's own account as principal for investment and not with
a view to resale or distribution, (ii) qualifies as an accredited investor under
Rule 501 of Reg.  D and (iii)  meets  such other  suitability  standards  as are
specified in the Memorandum  under the caption "Who Should Invest" and the other
conditions contained in the Subscription Agreement.

     (e)  You  will  maintain  a  record  of  all  information  obtained  by you
indicating that subscribers for Units meet the suitability standards referred to
in  Section  3(d)  hereof.  The  General  Partner  will  approve  or reject  the
subscriptions and notify you of the same.


     (f) You are a member in good standing of NASD Inc.

Section 4. Closings.


     During  the  Continuous  Offering,  closings  may be  held  as of the  last
business day of each month ("Monthly Closings").

Section 5. Covenants of the Partnership and the General Partner.


The Partnership and the General Partner covenant with you that:

     (a) If any event occurs before a Monthly  Closing and relates to or affects
the business or  condition  (financial  or other) of the General  Partner or the
Partnership  which makes it necessary to amend or supplement  the  Memorandum in
order that the  Memorandum  will not contain an untrue  statement  of a material
fact or omit to state a material fact  necessary in order to make the statements
therein not misleading in the light of the circumstances existing at the time it
is delivered to a subscriber,  the General  Partner  forthwith  will prepare and
furnish to you a reasonable  number of copies of the amendment or amendments of,
or  supplement  or  supplements  to,  the  Memorandum  (in  form  and  substance
satisfactory  to you and your  counsel)  that  will so amend or  supplement  the
Memorandum.

     (b) They will qualify or register the Units for offering and sale under, or
establish the exemption of the offering and sale of the Units from qualification
or  registration  under,  the  applicable  securities  or "blue sky" laws of the
jurisdictions  listed in Appendix I hereto and use their best efforts to qualify
in such other jurisdictions as you may reasonably request in writing;  provided,
however,  that  neither  of them will be  obligated  to  qualify  as a dealer in
securities  in any  jurisdiction  in which it is not so  qualified.  The General
Partner will promptly notify you in writing of such qualification,  registration
or exemption in each such  jurisdiction and of any  modification,  rescission or
withdrawal of any such  qualification,  registration  or exemption.  The General
Partner will not consummate a sale of a Unit in any  jurisdiction  in which such
sale may not be lawfully made and will not consummate any sale otherwise than in
accordance with the restrictions and limitations,  if any, set forth or referred
to in such survey.

     (c)  Neither  they nor any of their  affiliates  will,  either  directly or
through an agent (other than you),  sell or offer for sale, or solicit offers to
subscribe for or buy or approach potential offerees for, or otherwise  negotiate
in respect of, the Units  except for the  activities  of the General  Partner in
approaching  potential offerees undertaken in cooperation with you after advance
consultation with you.

     (d) The Partnership  will apply the proceeds from the sale of the Units for
the  purposes  set  forth  under  "Use  of  Proceeds"  in  the   Memorandum   in
substantially the amounts and at the times indicated thereunder.

     (e) Neither  they nor any person  directly or  indirectly  affiliated  with
either of them is or will be engaged, as a general partner, sponsor or otherwise
(i) in the organization or management of any partnership,  fund or other entity,
in a manner or under circumstances which, in the opinion of their counsel,  will
jeopardize  the status of the  offering of the Units as an exempted  transaction
under  the  Securities  Act or  under  the  laws of any  state  in  which  it is
represented  by them that the offering  may be made,  or (ii) in any offering of
securities  which,  when integrated with the offering of the Units in the manner
prescribed  by Rule 501(a) of Reg. D and SEC Release No.  33-4552 (Nov. 9, 1962)
will  jeopardize  the  status  of the  offering  of  the  Units  as an  exempted
transaction under Reg. D.

     (f) At all times  during the  Continuous  Offering  and before each Monthly
Closing,  they will (i) make  available to each  potential  purchaser and to the
purchaser's  representative,  if any,  such  information  (in  addition  to that
contained in the Memorandum) concerning  themselves,  the offering and any other
relevant matters, as they possess or can acquire without  unreasonable effort or
expense,  and (ii)  provide to each  potential  purchaser  and to any  purchaser
representatives  the  opportunity to ask questions of, and receive answers from,
them concerning the terms and conditions of the offering and the business of the
Partnership and to obtain any other additional  information,  to the extent they
possess  the same or can  acquire it  without  unreasonable  effort or  expense,
necessary to verify the accuracy of the  information  furnished to the potential
purchaser or any purchaser representatives.

     (g) Before each Monthly  Closing,  they will provide to each  purchaser the
information required to be delivered by Rule 502(b)(2)(iii) and 502(b)(iv).

     (h) Within 15 days of receiving from you copies of  information  indicating
that  subscribers  meet the  suitability  standards,  the General  Partner  will
approve or reject the subscriptions and notify you of the same.


                   (i) The General Partner has filed five copies of a notice on
Form D with the Securities and Exchange Commission no later than 15 days after
the first sale of a Unit pursuant to Rule 503 under Reg. D. The General Partner
shall comply with any filing requirement imposed by the laws of any state or
jurisdiction in which sales are made. The General Partner shall furnish you and
your counsel with copies of all filings made on Form D pursuant hereto.

Section 6. Payment of Expenses, Fees and Interest Income.

     The Partnership will pay its ongoing legal, accounting,  filing, reporting,
and data processing fees which are estimated at approximately  $50,000 annually.
In  consideration  for your  entering into this  Agreement,  you will act as the
Partnership's  commodity  broker/dealer  as described in the  Memorandum  and be
compensated  as described  in the  Memorandum  pursuant to a Second  Amended and
Restated Customer Agreement of even date herewith.

     All of the  Partnership's  funds will be  deposited  in cash in a commodity
brokerage  account  with you.  You will  deposit  the funds in  segregated  bank
accounts as required by the Commodity  Futures Trading  Commission  regulations.
Such  accounts  do not  earn  interest.  You will pay  monthly  interest  to the
Partnership  on 80% of the  average  daily  equity  maintained  in  cash  in the
Partnership's  brokerage  accounts  during each month at a 30-day  Treasury bill
rate.

with any person  with  respect to the Units,  only in such manner and under such
circumstances as are in compliance with the securities or "blue sky" laws of the
jurisdictions designated by you in accordance with Section 5(b) hereof.

Section 9. Indemnification and Contribution.

     You will  indemnify  and hold  harmless  the  Partnership  and the  General
Partner and their officers,  directors and employees,  against any and all loss,
liability,  claim,  damage,  expense,  judgment  or  amount  paid in  settlement
(including  reasonable  attorneys' fees) with respect to statements or omissions
in the  Memorandum  made with  respect  to you or your  obligations  under  this
Agreement made in reliance upon and in conformity with information  furnished to
the General Partner by you expressly for use in the Memorandum.
