                      DEAN WITTER SELECT FUTURES FUND L.P.
                  60,000 UNITS OF LIMITED PARTNERSHIP INTEREST
                                ----------------
 
    Dean Witter Select Futures Fund L.P. (the "Partnership") is a commodity pool
limited partnership formed  under the  laws of the  State of  Delaware which  is
engaged  primarily  in speculative  trading  of futures  and  forward contracts,
options on futures contracts  and on physical  commodities, and other  commodity
interests,  including  foreign currencies,  financial instruments,  precious and
industrial metals, energy products, and  agriculturals, as more fully  described
herein  (hereinafter referred  to collectively as  "futures interests"). Demeter
Management Corporation, the  general partner  of the  Partnership (the  "General
Partner"),  has retained  EMC Capital  Management, Inc.,  Rabar Market Research,
Inc., and Sunrise  Capital Management, Inc.  (individually, a "Trading  Advisor"
collectively; the "Trading Advisors"), to engage in futures interests trading on
behalf  of the Partnership. The  Partnership commenced futures interests trading
on August 1, 1991.
 
   
    Units of limited partnership interest in the Partnership ("Units") are being
offered for sale at a price equal to  100% of the Net Asset Value per Unit  (the
total  assets of the Partnership less its total liabilities allocated to capital
accounts  represented  by  Units  divided  by  the  aggregate  number  of  Units
outstanding)  as  of  the  close  of  business on  the  last  day  of  the month
immediately preceding the date of the applicable closing set forth below.  Units
will  be issued at the  first closing (the "First  Closing"), which is currently
scheduled to be held  on December 2, 1996;  provided, however, that the  General
Partner  may at its  discretion hold such  First Closing at  any time during the
Offering Period  (as defined  herein). Units  that remain  unsold following  the
First  Closing may be  offered for sale,  in the sole  discretion of the General
Partner, at a second closing, if any (the "Second Closing"), currently scheduled
to be held on  January 2, 1997.  Units that remain  unsold following the  Second
Closing  may be offered for sale, in the sole discretion of the General Partner,
at a third closing, if any (the "Third Closing"), currently scheduled to be held
on February 3, 1997. Units are being offered and sold by the Partnership through
Dean Witter Reynolds Inc. ("DWR") on a  best efforts basis. There is no  minimum
number of Units which must be sold for this offering to close.
    
 
    THESE  ARE SPECULATIVE SECURITIES  AND INVOLVE A HIGH  DEGREE OF RISK. THESE
SECURITIES ARE SUITABLE FOR INVESTMENT ONLY BY  A PERSON WHO CAN AFFORD TO  LOSE
HIS   ENTIRE   INVESTMENT.   SEE  "SUMMARY   OF   THE   PROSPECTUS--  INVESTMENT
REQUIREMENTS," (PAGE 1), "RISK FACTORS," (PAGE 13), AND "CONFLICTS OF  INTEREST"
(PAGE 21).
 
    An  investment in the Partnership  involves significant risks, including the
following:
 
       -Futures  interests  trading  is  speculative  and  volatile.  The
        Partnership's  trading has  been volatile.  Such volatility could
        result in an  investor losing all  or a substantial  part of  his
        investment.
 
   
       -The  Partnership is subject to substantial charges by the Trading
        Advisors and DWR. The Partnership must earn estimated annual  net
        trading  profits of 7.06% of its annual average Net Assets (after
        taking into account estimated interest income based upon  current
        rates  of 5%)  in order to  avoid depletion or  exhaustion of its
        assets. Investors should see "Break Even Analysis" on page 40 for
        the effect of redemption  charges which are  not included in  the
        above figures.
    
 
       -No  secondary  market for  Units  exists. Units  may  be redeemed
        monthly only  after the  end  of the  sixth month  following  the
        closing  at  which an  investor first  became a  Limited Partner.
        Units redeemed at or prior to the end of the twenty-fourth  month
        following  the closing at which an investor first purchased Units
        may be subject to  redemption charges. Certain market  conditions
        may   result  in  possible  delays   in,  or  inability  to  pay,
        redemptions.
 
       -Conflicts of interest between and among the Trading Advisors, the
        General Partner, DWR,  their affiliates and  the Partnership  may
        adversely  affect the trading performance of the Partnership. See
        "Conflicts of Interest."
 
       -The Partnership's  profitability  is  largely  dependent  on  the
        collective performance of the Trading Advisors.
 
       -While   the  General  Partner   does  not  intend   to  make  any
        distributions, profits earned in any year will result in  taxable
        income to investors.

<PAGE>
    The minimum investment for most subscribers is $5,000, or $2,000 in the case
of an Individual Retirement Account.
 
    Subject to redemption charges during the 24 months following the issuance of
a  Unit and certain other  restrictions, Units may be redeemed  as of the end of
any month. See "Redemptions."
 
    The Partnership is not a mutual fund or any other type of investment company
within the meaning of the Investment Company Act of 1940, as amended, and is not
subject to regulation thereunder.
 
NOTES TO TABLE ON FRONT COVER PAGE
 
   
(1) Units are offered for sale at each closing at a price per Unit equal to 100%
    of the Net Asset Value of a Unit as of the close of business on the last day
    of the month immediately  preceding the date of  the applicable closing.  No
    underwriting  compensation or  selling commissions will  be paid  out of the
    proceeds of this offering. However,  except as provided below, employees  of
    DWR  will receive from DWR (payable solely from its own funds) a gross sales
    credit equal to  3% of the  Net Asset Value  per Unit as  of the  applicable
    closing  for each Unit sold  by them and issued  at such closing. Commencing
    with the eighth month following  the closing at which  a Unit is issued  and
    continuing  until the  Partnership terminates, an  employee of  DWR who sold
    such Unit and who is properly registered with the Commodity Futures  Trading
    Commission  ("CFTC") and has passed the Series 3 or Series 31 examination or
    was "grandfathered"  as  an  associated person  qualified  to  do  commodity
    brokerage  also will receive from DWR (payable solely from its own funds) up
    to 35% of  the brokerage  commissions that are  attributable to  outstanding
    Units  sold  by  them  and  received by  DWR  as  commodity  broker  for the
    Partnership. During  the  period  August  1991  through  August  1996,  such
    compensation  resulted  in average  annual payments  of  $37 per  Unit. Such
    continuing compensation  is to  be  paid in  recognition of  the  employee's
    continuing  services to the Limited Partners.  For a description of all such
    continuing services, see "Plan of Distribution." The Selling Agreement among
    DWR, the General Partner, the Trading Advisors and the Partnership  provides
    that  such compensation may only be paid by DWR as long as such services are
    provided. Such  continuing compensation  paid by  DWR may  be deemed  to  be
    underwriting compensation. No part of such compensation shall be paid by the
    Partnership  and, accordingly, Net Assets will not be reduced as a result of
    such compensation.  No  person  will  receive  the  continuing  compensation
    described above who is not a DWR employee at the time of receipt of payment.
    
 
    DWR  will not pay to its employees the 3% gross sales credit described above
    with respect  to Units  purchased by  a subscriber  with the  proceeds of  a
    redemption  on  or after  December  31, 1995  of all  or  a portion  of such
    subscriber's interest  in any  other commodity  pool for  which the  General
    Partner  serves as  the general  partner and  commodity pool  operator. Such
    employees will receive  the continuing  payments with  respect to  brokerage
    commissions which are charged to the Partnership which are comparable to the
    payments  which were received  by such employees with  respect to such other
    commodity pools.
 
    DWR  will  be   indemnified  by  the   Partnership  against  certain   civil
    liabilities.
 
   
(2) Units  are offered for sale from  the date hereof, unless sooner terminated,
    to the date  of the First  Closing. Units that  remain unsold following  the
    First Closing may be offered for sale, in the sole discretion of the General
    Partner,  for a period from the date of the First Closing to the date of the
    Second Closing,  if  any. Units  that  remain unsold  following  the  Second
    Closing  may be  offered for  sale, in  the sole  discretion of  the General
    Partner, for a period from the date of the Second Closing to the date of the
    Third Closing, if any (the period  from the date of this Prospectus  through
    February  13, 1997 will be referred to herein as the "Offering Period"). The
    General Partner  may,  in its  discretion,  extend the  Offering  Period  to
    provide  for additional closings for the sale of Units, but in no event will
    the Offering Period be extended beyond March  10, 1997. In the event of  any
    such  extension, the term "Offering Period"  shall be deemed to include such
    additional closings. The General Partner  shall also have the discretion  to
    terminate  the offering  of Units  at any  time during  the Offering Period.
    Subscription amounts received during the Offering Period and not immediately
    rejected by the General Partner will be held in escrow at Chemical Bank, New
    York, New York (the  "Escrow Agent") until the  applicable closing or  until
    earlier  rejection by the General Partner. The funds will be invested in the
    Escrow Agent's interest-bearing bank  money market account. Interest  earned
    on  subscriptions  accepted  or  rejected by  the  General  Partner  will be
    credited to the subscribers' customer accounts with DWR. The General Partner
    will determine to accept or reject  a subscription generally within 10  days
    of  the  receipt  of  a  complete  and  executed  Subscription  and Exchange
    Agreement and Power of Attorney. See "Plan of Distribution."
    
 
    Any subscription received by DWR during  the last five business days of  the
    month  prior to a closing  and not rejected may be  held in escrow until the
    next closing. See "Plan of Distribution."
 
(3) DWR paid $665,132 in connection with the organization of the Partnership and
    the prior offerings  of Units.  Such costs included  legal, accounting,  and
    auditing  fees, printing costs,  filing fees, escrow  fees, marketing costs,
    and other related fees and expenses incurred in connection with the  initial
    and  second offerings of  Units. The Partnership will  not reimburse DWR for
    any portion of the costs so  incurred or any offering expense (estimated  to
    be  $875,000 in the  aggregate) incurred in  connection with this additional
    offering of  Units, and  while  DWR may  recoup  such costs  from  brokerage
    commissions  paid by the Partnership, the Partnership will not be liable for
    any such costs at  any time. Investments by  subscribers are not subject  to
    any  upfront  fees,  commissions  or expenses  and  therefore,  100%  of the
    proceeds of the offering  are available for  investment in the  Partnership.
    The  number of  Units sold will  have no effect  on the Net  Asset Value per
    Unit.

                           SUMMARY OF THE PROSPECTUS
                THE DATE OF THIS PROSPECTUS IS OCTOBER   , 1996.
    
 
    The following is a summary of this Prospectus. This Prospectus contains more
detailed  information under the captions referred  to below, and this summary is
qualified in its entirety by the information appearing elsewhere herein.
 
                            INVESTMENT REQUIREMENTS
 
    The minimum  investment for  most  subscribers is  $5,000, except  that  the
minimum  investment  is: (a)  $2,000  in the  case  of an  Individual Retirement
Account ("IRA"); or  (b) for subscribers  who redeem, on  or after December  31,
1995,  units of  limited partnership  interest in  any other  commodity pool for
which the  General Partner  serves as  the general  partner and  commodity  pool
operator and use the proceeds of such redemption (less any applicable redemption
charges)  to  purchase  Units (such  purchases  are hereinafter  referred  to as
"Exchanges"), the lesser of (i)  $5,000 ($2,000 in the  case of IRAs), (ii)  the
proceeds  from the redemption of  five units (or two units  in the case of IRAs)
from commodity pools other than the Spectrum Series, or (iii) the proceeds  from
the  redemption of 500  units (200 units  in the case  of IRAs) from  one of the
Spectrum Series of commodity pools. Existing Limited Partners who desire to make
an additional investment in the Partnership may subscribe for Units at a closing
with a minimum investment of $1,000.
 
    Subscribers should be aware that there  are minimum net worth and/or  annual
income  suitability standards which must be met in order to subscribe for Units.
Each subscriber  must  represent and  warrant  in a  Subscription  and  Exchange
Agreement  and  Power  of  Attorney  that  such  subscriber  has  received  this
Prospectus and that such subscriber meets the applicable State minimum financial
suitability standard set forth  in the Subscription  and Exchange Agreement  and
Power  of Attorney (which may require a  greater minimum investment), and may be
required to provide additional information regarding the subscriber's background
and investment  history.  Dean Witter  Reynolds  Inc. ("DWR")  and  its  account
executives  have a duty to determine that  this is a suitable investment for the
subscriber.
 
    Unless otherwise specified  in the Subscription  and Exchange Agreement  and
Power of Attorney under "State Suitability Requirements," a subscriber must have
either: (a) a net worth of at least $75,000 (exclusive of home, furnishings, and
automobiles),  or  (b) a  net  worth of  at  least $30,000  (exclusive  of home,
furnishings, and automobiles) and an annual income of at least $30,000.  Certain
jurisdictions  impose  more  restrictive suitability  and/or  minimum investment
requirements than those set forth above, including requirements for a higher net
worth, a higher annual  income, or both.  A list of  such jurisdictions and  the
restrictions  imposed is included in the Subscription and Exchange Agreement and
Power of Attorney under the heading "State Suitability Requirements." A specimen
form of the Subscription and Exchange Agreement and Power of Attorney is annexed
hereto as Exhibit B. Separate execution copies of the Subscription and  Exchange
Agreement  and  Power of  Attorney either  accompany this  Prospectus or  may be
obtained, after delivery of this Prospectus, from a local DWR branch office.
 
    Subject to certain limited revocation rights (see "Subscription Procedure"),
all subscriptions  for Units  are irrevocable  by subscribers,  and the  General
Partner  may, in  its sole  discretion, reject any  subscription in  whole or in
part. There are significant restrictions on the ability of a Limited Partner  to
redeem  Units,  and  although the  Partnership's  Limited  Partnership Agreement
permits the transfer of Units subject to certain conditions, there is no  public
market  for the Units and  none is likely to  develop. Therefore, a purchaser of
Units must  be  able  to  bear  the economic  risks  of  an  investment  in  the
Partnership  for  a significant  period of  time.  See "The  Limited Partnership
Agreement--Restrictions on Transfers or Assignments" and "Redemptions."

                             ADDITIONAL INFORMATION
 
    In addition to this  Prospectus, a sales  brochure and introductory  letters
prepared  by DWR may be delivered with this Prospectus or may be obtained from a
DWR account executive  or by  writing to Dean  Witter Reynolds  Inc., Two  World
Trade Center, 62nd Floor, New York, New York 10048.
 
                            THE INVESTMENT OBJECTIVE
 
    The objective of Dean Witter Select Futures Fund L.P. (the "Partnership") is
to generate substantial appreciation of its assets over time through speculative
trading.  The entire proceeds of the sale of  the Units will be deposited in the
Partnership's accounts  with DWR  to be  used as  margin for  the  Partnership's
trading   activities  and  may  be  subject  to  depletion  if  the  Partnership
experiences losses from its trading activities.
 
    The Partnership  will trade  futures contracts  and forward  contracts,  and
options  on futures  contracts and  on physical  commodities, and  other futures
interests pursuant to the trading  approaches utilized by the Trading  Advisors.
The  Partnership's portfolio will normally include contracts for diverse futures
interests,  including  industrial  items,  metals,  agriculturals,   currencies,
financial  instruments, and stock, financial, and  economic indexes. As a group,
the Trading Advisors employ a variety of trading systems in an effort to achieve
this objective, and  may from time  to time, in  their discretion, modify  their
trading  systems  and  add  to  and  delete  from  the  Partnership's  portfolio
additional futures  interests.  See "Investment  Program,  Use of  Proceeds  and
Trading Policies -- Trading Policies" and "The Trading Advisors."
 
   
    Based upon the fees and expenses of the Partnership, the Partnership will be
required  to  earn  estimated  annual  net  trading  profits  of  7.06%  of  the
Partnership's annual average  Net Assets  (after taking  into account  estimated
interest  income based upon current rates of  5%) in order to avoid depletion or
exhaustion of  the Partnership's  assets.  See "Description  of Charges  to  the
Partnership."  Investors should  see "Break  Even Analysis"  on page  40 for the
effect of redemption  charges which are  not included in  the above figures.  By
reason  of  the  foregoing,  investors  should  consider  an  investment  in the
Partnership as a long-term investment.
    
 
    Distributions of profits, if any, will be made at the sole discretion of the
General Partner. It  is currently the  intention of the  General Partner not  to
make distributions. See "Distributions" in this section.
 
                                THE PARTNERSHIP
 
    The  Partnership was  organized as a  limited partnership on  March 21, 1991
under the Delaware  Revised Uniform  Limited Partnership  Act (the  "Partnership
Act").  The offices of  the Partnership are  located at Two  World Trade Center,
62nd Floor, New York, New York 10048, telephone (212) 392-8899.
 
    The Partnership  was  initially  capitalized through  the  contributions  of
$1,000  by the  General Partner  and $1,000 by  an initial  limited partner. The
initial limited partner ceased to be a Limited Partner of the Partnership at the
Partnership's initial closing, which was held on August 1, 1991.
 
    The Partnership initially offered 75,000 Units through a public offering, in
which Units were  sold for $1,000  at the initial  closing, and at  100% of  Net
Asset  Value  ($938.03)  at  a supplemental  closing  (the  initial  closing and
supplemental closing, hereinafter, the  "Initial Offering"). During the  Initial
Offering,  the Partnership accepted $60,268,482  and issued 60,853.334 Units. In
accordance  with  the  Limited   Partnership  Agreement,  the  General   Partner
contributed $630,000 (635.284 General Partnership Units) to the Partnership. The
Partnership  had  a  second  offering  of Units  in  October  1993  (the "Second
Offering"). Units were offered at a price  equal to 100% of the Net Asset  Value
of  a  Unit on  the  last day  of the  month  immediately preceding  the closing
($1,567.26).   During   the   Second   Offering,   the   Partnership    accepted
$116,617,865.93  and  issued 74,408.337  Units. In  accordance with  the Limited
Partnership Agreement,  the  General  Partner  contributed  $1,050,000  (669.960
General Partnership Units) to the Partnership.

    The Partnership will terminate upon the first to occur of the following: (a)
December  31,  2025; (b)  the  withdrawal, insolvency,  bankruptcy, dissolution,
liquidation, or termination of the General Partner, unless a new general partner
has been  elected  and the  business  of the  Partnership  is continued  by  the
successor  general partner;  (c) an  election to  dissolve the  Partnership at a
specified time by Limited Partners owning more than 50% of the Units then  owned
by  Limited Partners; (d) a decline  in the Net Asset Value  of a Unit as of the
close of business (as determined by the General Partner) on any day to less than
$250; (e) a decline in the Partnership's Net Assets as of the close of  business
(as  determined by the  General Partner) on any  day to $250,000  or less; (f) a
determination by  the  General Partner  that  the Partnership's  Net  Assets  in
relation  to the operating  expenses of the Partnership  make it unreasonable or
imprudent to continue the business of the Partnership; (g) the occurrence of any
event which shall make it  unlawful for the existence  of the Partnership to  be
continued;  or  (h) a  determination  by the  General  Partner to  terminate the
Partnership following a  Special Redemption Date.  See "The Limited  Partnership
Agreement--Termination of the Partnership."
 
   
    The  Partnership commenced trading operations on  August 1, 1991. The actual
performance record of the Partnership  from the commencement of trading  through
August 31, 1996 is set forth under "Performance Record of the Partnership."
    
 
                              THE GENERAL PARTNER
 
   
    The  general  partner  and commodity  pool  operator of  the  Partnership is
Demeter Management Corporation, a Delaware corporation (the "General  Partner").
The General Partner and Dean Witter Reynolds Inc. ("DWR"), the selling agent and
commodity broker for the Partnership, are each wholly-owned subsidiaries of Dean
Witter,  Discover  &  Co. ("DWD").  See  "Conflicts of  Interest,"  "The General
Partner," and  "The Commodity  Broker." The  Trading Advisors  make all  trading
decisions  in respect of the  funds of the Partnership,  except that the General
Partner may override the  instructions of any Trading  Advisor and make  trading
decisions  under  certain circumstances.  See  "The Management  Agreements." The
General Partner is or has been  the general partner and commodity pool  operator
of  28 commodity pools, three of which have terminated. The General Partner had,
in the aggregate, approximately $950 million  of net assets under management  as
of August 31, 1996.
    
 
                              THE COMMODITY BROKER
 
    The  principal commodity broker for the  Partnership is Dean Witter Reynolds
Inc. (in  such capacity,  the "Commodity  Broker"). The  Commodity Broker  is  a
wholly-owned subsidiary of DWD and currently acts as commodity broker for all of
the  commodity pools for which  the General Partner acts  as general partner and
commodity pool  operator, as  well as  for other  commodity pools.  The  General
Partner  believes  that  the  commissions  and charges  payable  to  DWR  by the
Partnership are competitive  with those  paid by other  public commodity  pools,
although  they may be higher than those  paid by certain other customers of DWR.
See "Conflicts of  Interest," "Description  of Charges to  the Partnership--  2.
Dean Witter Reynolds Inc.," and "The Commodity Broker."
 
                              THE TRADING ADVISORS
 
    The  trading advisors for  the Partnership are  EMC Capital Management, Inc.
("EMC"), Rabar Market Research, Inc. ("Rabar"), and Sunrise Capital  Management,
Inc. ("Sunrise") (formerly Sunrise Commodities, Inc.), (individually, a "Trading
Advisor"; collectively, the "Trading Advisors"). Subject to certain limitations,
the  Trading  Advisors  have  authority  and  responsibility  for  directing the
investment and reinvestment in  futures interests of  their allocated shares  of
the Partnership's Net Assets. See "The Management Agreements." Since the primary
purpose  of the  Partnership is  to achieve  appreciation of  its assets through
speculative trading in futures interests,  the Partnership's ability to  succeed
in  that endeavor  depends on the  collective success of  the respective trading
approaches of the Trading Advisors.
 
                                       3
<PAGE>
    The assets  of the  Partnership  are traded  pursuant to  technical  trading
systems  developed by the Trading  Advisors. Technical systems formulate trading
decisions on an  analysis of prior  historical patterns of  price movements  and
other market indicators such as volume and market behavior. The trading programs
of EMC and Sunrise are pure technical systems. Rabar's trading program is also a
technical   system,  but  incorporates  analysis  of  key  fundamental  factors,
particularly for risk control purposes.  See "The Trading Advisors--EMC  Capital
Management,  Inc.--Description  of  EMC's  Trading  Approach,"  "--Rabar  Market
Research, Inc.--Description of Rabar's Trading Approach," and "--Sunrise Capital
Management, Inc.--Description  of Sunrise's  Trading  Approach." See  also  "The
Futures, Options and Forward Markets."
 
    Immediately   following  each  closing,   the  General  Partner  anticipates
allocating the  proceeds  of such  closing  to  the management  of  the  Trading
Advisors  in equal proportions. The General Partner, however, has the discretion
to reallocate Net  Assets among  EMC, Rabar,  and Sunrise.  See "The  Management
Agreements--Allocation and Reallocation of the Partnership's Net Assets."
 
    The Trading Advisors are not affiliated with the General Partner or DWR. See
"The Trading Advisors" and "The Management Agreements."
 
                                  RISK FACTORS
 
    As  a general  matter, an investment  in the Partnership  is speculative and
involves substantial risk,  including the risk  of loss of  a Limited  Partner's
entire investment. Risks of an investment in the Partnership include:
 
RISKS RELATING TO FUTURES INTERESTS TRADING
 
       -Futures  interests  trading is  speculative  and volatile  and an
        investor may lose all or a substantial part of his investment.
 
       -Futures interests  trading  is highly  leveraged  and  relatively
        small  price movements  can result  in significant  losses to the
        Partnership.
 
       -Futures  interests  trading  may  be  illiquid  and  in   certain
        situations  prevent the Partnership from  limiting its loss on an
        unfavorable position.
 
       -Trading in  forward  contracts  may subject  the  Partnership  to
        losses if a counterparty is unable to meet its obligations.
 
       -Trading on foreign exchanges may result in the Partnership having
        less   regulatory   protection   available.   In   addition,  the
        Partnership may suffer losses due to exchange rate changes.
 
       -Trading in futures options can  be extremely expensive if  market
        volatility is incorrectly predicted.
 
       -The  Partnership has credit risk because  DWR acts as the futures
        commission merchant or the sole counterparty with respect to most
        of the Partnership's assets.
 
       -Speculative position limits may result in the Partnership  having
        to liquidate profitable positions.
 
RISKS RELATING TO THE PARTNERSHIP AND OFFERING OF UNITS
 
       -Past results are not necessarily indicative of future results.
 
   
       -The  Partnership incurs substantial charges regardless of whether
        it realizes profits. The  Partnership must earn estimated  annual
        net  trading profits  of 7.06% of  its annual  average Net Assets
        (after   taking   into   account   estimated   interest    income
    
 
                                       4
<PAGE>
        based  upon current rates  of 5%) in order  to avoid depletion or
        exhaustion of its assets. The Partnership had net trading  losses
        in  1996 year-to-date, 1994 and  1992. See "Performance Record of
        the Partnership."
 
       -Restricted investment  liquidity  in  the  Units,  absence  of  a
        secondary  market,  ability  to  assign  or  transfer restricted,
        redemptions limited to  monthly after the  first six months,  and
        redeemed Units may be subject to redemption charges.
 
       -Significant  actual  and  potential conflicts  of  interest exist
        among the General Partner, the Trading Advisors and the Commodity
        Broker.
 
       -Limited Partners  do not  participate in  the management  of  the
        Partnership or in the conduct of its business.
 
       -Limited  Partners must rely on the General Partner's selection of
        trading advisors.
 
RISKS RELATED TO THE TRADING ADVISORS
 
       -The  Partnership  will  not  be  profitable  unless  the  Trading
        Advisors   are   collectively  successful   with   their  trading
        strategies.
 
       -Market factors may adversely affect or require modifications to a
        Trading Advisor's strategy.
 
       -Management Agreements may not be renewed, may be renewed on  less
        favorable  terms to  the Partnership, or  may be  terminated by a
        Trading Advisor such  that a  Trading Advisor will  no longer  be
        available to the Partnership.
 
       -Reallocation of assets among the Trading Advisors could result in
        an  increase in assets to a  Trading Advisor who may subsequently
        incur trading losses.
 
       -Substantial increase in assets allocated to a Trading Advisor may
        adversely affect its performance.
 
       -The Trading Advisors'  primarily technical  trading systems  have
        inherent limitations.
 
       -Increases  in the use of technical trading systems in the futures
        interests markets  could  adversely  alter  trading  patterns  or
        affect execution of trades by the Partnership.
 
TAXATION RISKS
 
       -If  the tax laws  and/or certain facts  and circumstances change,
        the Partnership may be taxed as a corporation.
 
       -Profits earned during any year  will result in taxable income  to
        an  investor even though  the General Partner  does not intend to
        make distributions.
 
       -Deductibility of  certain of  the Partnership's  expenses may  be
        limited.
 
       -The  Partnership's  tax return  may  be audited  by  the Internal
        Revenue Service.
 
    Only  the  General  Partner  will  be  liable  for  Partnership  obligations
(including  margin calls) to the extent that the Partnership's assets, including
amounts contributed by the Limited Partners and amounts paid to Limited Partners
upon redemptions, distributions  or otherwise (together  with interest  thereon)
are  insufficient to  meet those  obligations. See  "Risk Disclosure Statement,"
"Risk  Factors,"  "Conflicts  of  Interest,"  "Description  of  Charges  to  the
Partnership,"   and   "The   Limited   Partnership   Agreement--Nature   of  the
Partnership."

                             CONFLICTS OF INTEREST
 
    Significant  actual  and  potential  conflicts  of  interest  exist  in  the
structure  and  operation  of  the  Partnership,  principally  arising  from the
affiliation between  the General  Partner  and DWR,  and  the trading  of  other
accounts  of, or managed by, the General  Partner, DWR, the Trading Advisors and
their  affiliates.  Such   conflicts  include  the   fact  that  the   brokerage
arrangements  were  not  agreed upon  in  arm's-length negotiations  due  to the
affiliation between the General  Partner and DWR, and  that the General  Partner
and  DWR may have conflicting demands in  respect of other commodity pools; that
DWR employees selling Units will receive a portion of the brokerage  commissions
paid  to DWR by the Partnership, and  thus have a conflict in advising investors
whether and  when  to redeem  Units;  that the  Trading  Advisors and  DWR,  and
individuals  and  entities  associated  with the  General  Partner,  the Trading
Advisors and DWR,  may trade  futures interests  for their  own accounts,  which
trading  may compete  with the  Partnership for  positions; that  trading by the
Trading Advisors for their own accounts and for other customers could result  in
application of position limits to restrict the Partnership's trading; that under
the  customer agreement with DWR,  DWR may close out  positions and take certain
other  actions  with   regard  to   the  Partnership's   accounts  without   the
Partnership's  consent; and  that other commodity  pools managed  by the General
Partner  and  the  Trading  Advisors  may  compete  with  the  Partnership.  See
"Conflicts of Interest," "The Trading Advisors," "The General Partner," and "The
Commodity Broker."
 
                   DESCRIPTION OF CHARGES TO THE PARTNERSHIP
 
    The Partnership is subject to substantial charges which are summarized below
and  described in detail under "Description  of Charges to the Partnership." See

                                                                     during a calendar year.

                       taking delivery of futures interests).
</TABLE>
    
 
    As long as redemption charges are imposed, as described under "Redemptions,"
the management fee, incentive fee and caps on brokerage commissions, transaction
fees and costs, ordinary  administrative expenses, and  net excess interest  and
compensating  balance benefits  may not be  increased. Thereafter,  none of such
fees and caps may  be increased unless Limited  Partners are given prior  notice
thereof  and an opportunity to redeem  their Units, subject to additional limits
described under "Description of Charges to the Partnership."
 
                                       7

    Based on the annual  fees and expenses of  the Partnership described  above,
the  Partnership must  earn annual  trading profits  (after taking  into account
estimated interest  income based  upon current  rates  of 5%)  of 7.06%  of  the
Partnership's  annual  average  Net  Assets  in  order  to  avoid  depletion  or
exhaustion of the assets of the Partnership.  In order for a Limited Partner  to
pay  the redemption  charge and  recoup its  initial investment  upon redemption
after one year,  the Partnership must  earn trading profits  (after taking  into
account  estimated interest income based upon current  rates of 5%) of 10.16% of
the Partnership's  annual average  Net Assets.  This assumes  that each  Trading
Advisor's  gross profits equal expenses, such  that no incentive fees are earned
by the  Trading  Advisors.  For  the  actual  fees  and  expenses  paid  by  the
Partnership  during  fiscal  year  1995,  see  "Description  of  Charges  to the
Partnership."
    
 
                                  REDEMPTIONS
 
    A Limited Partner may require the Partnership to redeem all or part of  such
Limited  Partner's Units effective  as of, but  not before, the  last day of the
sixth month-end  following the  closing at  which such  person first  becomes  a
Limited  Partner,  in  the manner  described  herein. Thereafter,  Units  may be
redeemed as of the end of any month.  However, any Units redeemed at the end  of
the  twelfth, eighteenth, or twenty-fourth month  following the closing at which
such Units were issued will be assessed  a redemption charge equal to 3%, 2%  or
1%,  respectively,  of  the Net  Asset  Value of  a  Unit  on the  date  of such
redemption. The foregoing charges will be paid to DWR.
 
    A limited partner in any of the other commodity pools for which the  General
Partner  serves as the general partner  and commodity pool operator who redeemed
all or a portion of his interest in  one of such other partnerships on or  after
December  31, 1995  and purchases  Units will not  be subject  to the redemption
charges or restrictions under the circumstances described herein. The number  of
Units  (determined on a per  closing basis), expressed as  a percentage of Units
purchased, which  are  not subject  to  a  redemption charge  is  determined  by
dividing (a) the dollar amount received upon redeeming an interest in such other
partnership  and  used to  purchase Units  by  (b) the  total investment  in the
Partnership. For example, a limited  partner who receives $5,000 upon  redeeming
all  or a  part of  his interest  in a  commodity pool  operated by  the General
Partner and  invests  $10,000  in the  Partnership  will  not be  subject  to  a
redemption charge on 50% of his Units. Redemptions of Units will be deemed to be
in  the order in which  they are purchased (assuming  purchases at more than one
closing), with the Units not subject to  a redemption charge being deemed to  be
the  first Units purchased at  a closing. An investor  who purchases $500,000 or
more of Units will not be subject to the redemption charges described above.
 
    A redemption may  be made  only in  whole Units  or in  multiples of  $1,000
(which  may  result in  the redemption  of fractional  Units), unless  a Limited
Partner's entire interest in  the Partnership is redeemed.  The right to  obtain
redemption  is  contingent  upon  the Partnership  having  assets  sufficient to
discharge its  liabilities (including  any  amounts owed  to affiliates  of  the
General  Partner) as of the month-end,  and the General Partner's timely receipt
of a properly executed Request for Redemption. The Partnership may be forced  to
liquidate  open positions to satisfy  redemptions in the event  it does not have
sufficient cash on hand. See "Redemptions" and "Subscription Procedure."
 
    In addition  to  the information  and  reports described  below  under  "The
Limited Partnership Agreement--Reports to Limited Partners," the General Partner
will  provide Limited Partners with such  other information and will comply with
any such  procedures  in  connection  with redemptions  as  in  the  future  are
specifically  required  under  Securities  and  Exchange  Commission  rules  and
policies for commodity pools and similar investment vehicles.
 
                                 DISTRIBUTIONS
 
    Distributions of profits, if any, will be made at the sole discretion of the
General Partner (the General Partner  has not previously made any  distributions
of  profits and it is currently the intention of the General Partner not to make
distributions). It  is possible  that  no distributions  will  be made  in  some
 
                                       8
<PAGE>
years  in which  the Partnership  has taxable  profits, realized  or unrealized.
However, a Limited  Partner will  nevertheless be  required to  account for  his
share  of such profits as income for  federal tax purposes. Distributions may be
made by credit to a Limited  Partner's customer account with DWR. See  "Material
Federal Income Tax Considerations."
 
                            TRANSFERABILITY OF UNITS
 
    The  assignability or  transferability of  Units is  limited by  the Limited
Partnership Agreement and  no assignee  or transferee may  become a  substituted
Limited  Partner without the  consent of the General  Partner, which consent the
General  Partner  may  withhold  in  its  sole  discretion.  See  "The   Limited
Partnership Agreement--Restrictions on Transfers or Assignments."
 
                                  THE OFFERING
 
SECURITIES OFFERED
 
    60,853.334  Units were sold  to the public  during the Partnership's Initial
Offering. The Partnership sold an additional 74,423.953 Units during the  Second
Offering.  The Partnership is  currently offering up  to 60,000 additional Units
for sale. No  Units held by  existing Limited  Partners are being  sold in  this
offering.  The  General  Partner,  in  its  discretion,  may  register  and sell
additional Units from time to time.
 
SUBSCRIPTION PROCEDURE
 
    The minimum subscription for most subscribers is $5,000, except the  minimum
subscription  is:  (a) $2,000  in the  case of  an IRA;  or (b)  for subscribers
effecting Exchanges, the lesser of (i) $5,000 ($2,000 in the case of IRAs), (ii)
the proceeds from the redemption of five  units (two units in the case of  IRAs)
from  commodity pools other than the Spectrum Series, or (iii) the proceeds from
the redemption of  500 units (200  units in the  case of IRAs)  from one of  the
Spectrum Series of commodity pools. Existing Limited Partners who desire to make
an additional investment in the Partnership may subscribe for Units at a closing
with  a minimum  investment of $1,000.  Certain jurisdictions  may impose higher
minimum investment  requirements; see  "State Suitability  Requirements" in  the
Subscription   and  Exchange  Agreement  and   Power  of  Attorney.  No  selling
commissions will  be charged  on  subscriptions. No  offering expenses  will  be
charged  to investors or  the Partnership. See  "Investment Requirements" above,
"Plan of Distribution," and "Subscription Procedure."
 
    In order to purchase Units, a subscriber must complete, execute, and deliver
an execution  copy of  the  Subscription and  Exchange  Agreement and  Power  of
Attorney  to  DWR.  In the  Subscription  and  Exchange Agreement  and  Power of
Attorney, a  subscriber  will (i)  authorize  the  General Partner  and  DWR  to
transfer the subscription amount from the subscriber's customer account with DWR
to  the Dean Witter Select Futures Fund L.P. Escrow Account, or (ii) in the case
of an Exchange, authorize the General Partner to redeem all or a portion of such
subscriber's interest in another  commodity pool for  which the General  Partner
serves  as general partner and commodity pool  operator (subject to the terms of
the applicable  limited partnership  agreement)  and use  the proceeds  of  such
redemption  (less any  applicable redemption charges)  to purchase  Units in the
Partnership. A  subscriber must  have  the appropriate  amount in  his  customer
account  with  DWR  on  the  first business  day  following  the  date  that his
Subscription and Exchange Agreement  and Power of Attorney  is received by  DWR,
and  DWR will debit the  customer account and transfer  such funds to the escrow
account with  the  Escrow  Agent on  that  date.  A subscriber  may  revoke  his
Subscription  and Exchange Agreement  and Power of Attorney,  and receive a full
refund of the subscription  amount and any accrued  interest thereon (or  revoke
the redemption of units in the other commodity pool in the case of an Exchange),
within  five business days  after execution of  such Agreement or  no later than
3:00 p.m., New York City time, on the date of the applicable closing,  whichever
comes first, by delivering written notice to his DWR account executive.
 
PLAN OF DISTRIBUTION
 
    The  Units  are  being offered  and  sold  by the  Partnership  through DWR.
Pursuant to a Selling Agreement among the Partnership, the General Partner,  the
Trading  Advisors and DWR, DWR will use its  best efforts to sell Units, but DWR
has  not   made  any   commitment  to   offer  and   sell  a   specific   amount
 
                                       9
<PAGE>
   
of  Units or  to purchase  any Units.  See "Plan  of Distribution."  The General
Partner, in its sole discretion, may reject  a subscription in whole or in  part
at  any time  prior to acceptance.  Units are being  offered to the  public at a
price per Unit equal to 100% of the Net Asset Value of a Unit as of the close of
business on the  last day of  the month  immediately preceding the  date of  the
applicable  closing set forth below. Units will  be issued at the First Closing,
which is currently scheduled to be held on December 2, 1996; provided,  however,
that  the General Partner may  at its discretion hold  such First Closing at any
time during the  Offering Period (as  defined below). Units  that remain  unsold
following  the First Closing may be offered  for sale, in the sole discretion of
the General Partner,  at a  Second Closing, currently  scheduled to  be held  on
January  2, 1997. Units that  remain unsold following the  Second Closing may be
offered for sale,  in the sole  discretion of  the General Partner,  at a  Third
Closing, currently scheduled to be held on February 3, 1997. The General Partner
shall  have the discretion to  terminate the offering of  Units at any time. The
period from  the date  of this  Prospectus  through February  13, 1997  will  be
referred  to herein as  the "Offering Period."  The General Partner  may, in its
discretion, extend the Offering Period to provide for an additional closings for
the sale of Units, but in no  event will the Offering Period be extended  beyond
March  10, 1997. In the event of  any such extension, the term "Offering Period"
shall be deemed to include such additional closings.
    
 
    Funds with respect to a subscription received during the Offering Period and
not immediately rejected by the General Partner will be transferred to, and held
in escrow by, Chemical Bank (the "Escrow Agent"), as described above, until  the
General Partner either rejects such subscription prior to the applicable closing
or accepts such subscription at such closing.
 
    The  General Partner,  DWR, and the  Trading Advisors,  and their respective
principals, directors,  officers, employees  and affiliates,  may subscribe  for
Units.   Subject  to  certain  limited   revocation  rights  (see  "Subscription
Procedure"),  all  subscriptions  for  Units  are  irrevocable  by  subscribers.
Interest  earned on subscriptions deposited  into escrow and thereafter rejected
by the General  Partner will be  credited to the  subscriber's customer  account
with DWR.
 
    Employees  of  DWR will  receive  compensation from  DWR,  and not  from the
Partnership, out of the  brokerage commissions paid to  DWR by the  Partnership.
Such  continuing compensation is in consideration of certain additional services
provided to Limited Partners by  such persons on a  continuing basis and may  be
deemed to be additional underwriting compensation. See "Plan of Distribution."
 
NO SELLING COMMISSIONS OR OFFERING EXPENSE CHARGE
 
    In  connection with  the offering of  Units pursuant to  this Prospectus, no
selling commissions or offering expenses will be paid by Limited Partners or the
Partnership. DWR has  previously paid all  of the organizational  costs and  the
costs  relating to the Initial Offering  and Second Offering of the Partnership,
and will pay  all of  the costs  incurred in  connection with  this offering  of
Units,  estimated to be approximately $875,000 in the aggregate. The Partnership
will not reimburse DWR for any portion of the costs so incurred, and will not be
liable for any such costs at any  time (although DWR may recoup such costs  from
brokerage  commissions paid  by the  Partnership). Except  as otherwise provided
herein, employees of DWR will receive from DWR (solely from its own funds) gross
sales credit equal to 3%  of the Net Asset Value  per Unit as of the  applicable
closing  for each Unit sold by them and issued at such closing, and, if properly
registered with the CFTC, also will receive from DWR (solely from its own funds)
up to 35%  of the  brokerage commissions  that are  attributable to  outstanding
Units  sold by them and received by  DWR as commodity broker for the Partnership
each month, beginning with the eighth month after which such Unit was issued, as
described in Note (1) to the table  on the front cover page of this  Prospectus.
See  "Plan of Distribution." DWR's employees may  have a conflict of interest in
rendering advice to  Limited Partners  as to when  and whether  to redeem  Units
because  of  their interest  in  receiving certain  continuing  compensation for
ongoing services  rendered to  holders of  outstanding Units.  The  compensation
described above will be paid by DWR and will not be paid directly by any Limited
Partner or the Partnership.

SUITABILITY STANDARDS
 
    Each  investor (or person  entitled to exercise control  over assets of such
investor's account under an IRA or  other employee benefit plan) must  represent
and  warrant in  the Subscription and  Exchange Agreement and  Power of Attorney
that such  investor  and/or  other  person  has  received  this  Prospectus  and
satisfies  certain  investment and/or  suitability requirements  described under
"--Investment Requirements" above.
 
                         INTEREST ON PARTNERSHIP ASSETS
 
    Once the Partnership's assets are deposited  with DWR, they will be held  in
customer  segregated funds accounts established by  DWR. Effective on the day of
the First Closing, DWR  will credit the Partnership  at month-end with  interest
income  as if 80%  of the Partnership's  average daily Net  Assets for the month
were invested at a prevailing rate on U.S. Treasury Bills. For purposes of  such
interest  payments, Net Assets do  not include monies due  the Partnership on or
with respect to forward contracts and  other futures interests but not  actually
received   by  it  from   banks,  brokers,  dealers,   and  other  persons.  The
Partnership's assets  held  by  DWR shall  be  used  as margin  solely  for  the
Partnership's  trading. The Partnership's  funds will be  invested together with
other customer segregated  funds or  will be held  in non-interest-bearing  bank
accounts.  In either case, the Partnership will be credited with interest at the
rate earned  by  DWR  on  its  U.S.  Treasury  Bill  investments  with  customer
segregated funds (as if 80% of its assets were invested in U.S. Treasury Bills);
DWR  will  retain any  interest earned  in excess  of the  interest paid  to the
Partnership. To  the extent  that the  assets  of the  Partnership are  held  in
non-interest-bearing  bank accounts,  DWR or  its affiliates  would benefit from
compensating balance treatment in connection with  the designation of a bank  or
banks  in  which  the  Partnership's  assets are  deposited  (I.E.,  DWR  or its
affiliates will receive favorable loan rates  from such bank or banks by  reason
of  such deposits). It is not possible to quantify compensating balance benefits
at present; however, while it is anticipated that such benefits will exceed  the
interest  required to be credited to the  Partnership, it is estimated that they
should not exceed 4% of the  Partnership's average annual Net Assets after  such
credits.  To  the extent  such  benefits to  DWR  or its  affiliates  exceed the
interest DWR is obligated to credit to the Partnership, they will not be  shared
with  the  Partnership.  Notwithstanding  the foregoing,  the  aggregate  of (i)
brokerage commissions and transaction fees and costs payable by the Partnership,
and (ii) the net excess interest and compensating balance benefits to DWR or its
affiliates (after crediting  the Partnership with  interest as described  above)
shall not exceed 14% annually of the Partnership's average monthly Net Assets as
of  the  last day  of  each month  during  each calendar  year.  See "Investment
Program, Use of Proceeds and Trading Policies."
 
                                USE OF PROCEEDS
 
    The entire proceeds of  this offering, together  with the General  Partner's
capital contribution, will be deposited in the Partnership's accounts maintained
with  DWR, and used  for trading in futures  interests. See "Investment Program,
Use of Proceeds and Trading Policies."
 
                               TAX CONSIDERATIONS
 
    In the opinion of the General Partner's tax counsel, the Partnership will be
classified as  a partnership  for federal  income  tax purposes  and not  as  an
association  taxable as a corporation. Accordingly,  the Partnership will not be
subject to federal  income tax. Each  Limited Partner in  computing his  federal
income  tax liability for a  taxable year will be  required to take into account
his distributive share of all items of Partnership income, gain, loss, deduction
or credit for  the taxable year  of the  Partnership ending within  or with  the
taxable  year of the Limited Partner, regardless of whether such Limited Partner
has received any distributions from  the Partnership. Such items of  Partnership
gain  or loss retain their character  (E.G., capital or ordinary) when allocated
to the  Limited  Partners.  Moreover,  all such  allocations  will  increase  or
decrease  each  Limited  Partner's  tax  basis  in  his  Units.  The  allocation
 
                                       11
<PAGE>
provisions are designed  to reconcile tax  allocations to economic  allocations;
however,  no assurance can be  given that the Internal  Revenue Service will not
challenge  such  allocation,  especially  in  light  of  recently  issued  final
regulations. See "Material Federal Income Tax Considerations."
 
    Taxes payable by partners with respect to Partnership profits may exceed the
amount  of Partnership distributions, if any, for a taxable year. Based upon the
current and contemplated activities of the Partnership, the General Partner  has
been  advised by  its legal  counsel that,  in such  counsel's opinion, expenses
incurred by the  Partnership should  not be subject  to the  limitations on  the
deductibility  of certain miscellaneous itemized  expenses, except to the extent
that the Internal Revenue Service promulgates regulations that so provide.
 
    Cash distributions  by  the  Partnership  and  amounts  received  or  deemed
received  upon the partial  or complete redemption of  a Limited Partner's Units
that do not exceed the  Limited Partner's aggregate basis  in his Units are  not
taxable.  However,  to the  extent cash  distributions  and amounts  received or
deemed received upon the partial redemption of a Limited Partner's Units  exceed
the  Limited Partner's  aggregate tax  basis in  his Units,  the excess  will be
taxable to the Limited Partner as though it were gain on the sale of his  Units.
Loss  will generally be  recognized on a  redemption of Units  only if a Limited
Partner redeems all of his Units in the Partnership and, following the  complete
redemption,  such Limited Partner has remaining tax-basis in the Partnership. In
such case,  the  Limited  Partner will  recognize  loss  to the  extent  of  the
remaining  basis.  Subject  to an  exception  for certain  types  of Partnership
assets, such gain or  loss (assuming that the  Units constitute capital  assets)
will  be either  short-term capital  gain or loss  or long-term  capital gain or
loss, depending  upon the  length of  time that  Units were  held prior  to  the
distribution or redemption. See "Material Federal Income Tax Considerations."
 
    The  General Partner has been advised that, in the opinion of its counsel, a
Limited Partner  who is  a nonresident  alien individual,  foreign  corporation,
foreign  partnership,  foreign  trust,  or foreign  estate  (a  "Foreign Limited
Partner") should not  be deemed engaged  in a  trade or business  in the  United
States,  and should not be  subject to United States  federal income tax, solely
because such Foreign Limited Partner is a limited partner in the Partnership. In
the event the  Partnership's activities  should in  the future  not fall  within
certain  safe harbors from U.S.  trade or business status,  there is a risk that
all of  a  Foreign  Limited  Partner's  distributive  share  of  income  of  the
Partnership  would be  treated as  effectively connected  with the  conduct of a
trade or  business in  the United  States. In  that event,  the Foreign  Limited
Partner  would be taxed at regular rates  applicable to U.S. taxpayers and, if a
foreign corporation, could be subject to a 30% branch profits tax. See "Material
Federal Income Tax Considerations." As regards tax-exempt Limited Partners,  see
"Purchases by Employee Benefit Plans--ERISA Considerations."

<PAGE>
                                  RISK FACTORS
 
    In  addition to the Risk Disclosure  Statement appearing at the beginning of
this Prospectus,  prospective subscribers  should consider  the following  risks
before subscribing for Units.
 
RISKS RELATING TO FUTURES INTERESTS TRADING AND THE FUTURES INTERESTS MARKETS
 
    FUTURES  INTERESTS TRADING IS  SPECULATIVE AND VOLATILE.   Futures interests
prices are highly volatile. Price movements of futures interests are  influenced
by,  among  other things:  changing  supply and  demand  relationships; weather;
agricultural,  trade,  fiscal,  monetary,  and  exchange  control  programs  and
policies  of governments; domestic and foreign political and economic events and
policies; and  changes in  interest rates.  The Partnership's  trading has  been
volatile. See "Performance Record of the Partnership."
 
    The  Partnership  is also  subject  to the  risk of  failure  of any  of the
exchanges on which it  trades or of their  clearinghouses, if any. In  addition,
under  certain  circumstances,  such  as  the inability  of  a  customer  of the
Commodity  Broker  or  the  Commodity  Broker  itself  to  satisfy   substantial
deficiencies  in such  customer's account, the  Partnership may be  subject to a
risk of  loss of  its funds  on deposit  with such  Commodity Broker.  See  "The
Futures, Options and Forward Markets."
 
    FUTURES  INTERESTS TRADING IS  HIGHLY LEVERAGED.  Because  of the low margin
deposits normally required  in futures interests  trading (typically between  2%
and  15% of  the value  of the  contract purchased  or sold),  an extremely high
degree of  leverage is  typical of  a futures  interests trading  account. As  a
result,  a relatively small price  movement in a futures  interest may result in
immediate  and  substantial  losses  to  the  investor.  The  Partnership   uses
substantial  leverage which could, depending on performance, result in increased
gain or loss. See  "Performance Record of the  Partnership." For example, if  at
the  time of purchase 10% of  the price of a contract  is deposited as margin, a
10% decrease in the price of the contract would, if the contract is then  closed
out,  result in  a total  loss of  the margin  deposit before  any deduction for
brokerage commissions. A decrease  of more than  10% would result  in a loss  of
more  than  the total  margin  deposit. See  "The  Futures, Options  and Forward
Markets--  Margins"  and  "The  Limited  Partnership  Agreement--Nature  of  the
Partnership."
 
    FUTURES  INTERESTS  TRADING MAY  BE ILLIQUID.    Most United  States futures
exchanges limit fluctuations in certain futures interests prices during a single
day by regulations  referred to as  "daily price fluctuation  limits" or  "daily
limits." Pursuant to such regulations, during a single trading day no trades may
be  executed at prices beyond  the daily limits. Once  the price of a particular
futures interest has  increased or  decreased by an  amount equal  to the  daily
limit,  positions in  the futures interest  can neither be  taken nor liquidated
unless traders are willing to  effect trades at or  within the limit. Prices  in
various  futures interests have  occasionally moved the  daily limit for several
consecutive days with little  or no trading.  Similar occurrences could  prevent
the  Partnership from promptly liquidating  unfavorable positions and subject it
to substantial losses. While  daily limits may  reduce or effectively  eliminate
the liquidity of a particular market, they do not limit ultimate losses, and may
in  fact substantially increase losses because  they may prevent the liquidation
of unfavorable positions. There is no limitation on daily price moves in trading
currency forward contracts.
 
    In addition, the Partnership may not be able to execute trades at  favorable
prices  if little  trading in  the futures  interests involved  is taking place.
Under some circumstances,  the Partnership  may be  required to  accept or  make
delivery  of the underlying commodity if the position cannot be liquidated prior
to its expiration  date. See "Investment  Program, Use of  Proceeds and  Trading
Policies--Trading  Policies." It also  is possible that an  exchange or the CFTC
may  suspend  trading  in  a   particular  futures  interest,  order   immediate
liquidation  and  settlement of  a particular  futures  interest, or  order that
trading in  a particular  futures interest  be conducted  for liquidation  only.
Similarly,  trading  in  options on  a  particular futures  interest  may become
restricted if trading in the underlying futures interest has become  restricted.
During  periods in  October 1987,  for example,  trading in  certain stock index
futures was too  illiquid for  markets to function  efficiently and  was at  one
point  actually suspended. See  "The Futures, Options  and Forward Markets." The
principals who deal in the forward contract markets are
 
                                       13
<PAGE>
not required to continue  to make markets in  the forward contracts they  trade.
There  have been  periods during which  certain participants  in forward markets
have refused to quote prices for forward contracts or have quoted prices with an
unusually wide spread between the  price at which they  are prepared to buy  and
that at which they are prepared to sell.
 
   
    SPECIAL  RISKS ASSOCIATED WITH  FORWARD TRADING.   The Partnership trades in
forward  contracts,  primarily   currency  forward  contracts.   Based  on   the
Partnership's trading from August 1991 through August 1996 and the allocation of
assets  among  the  Trading  Advisors, forward  contracts  are  expected  to, on
average, comprise approximately 5-10% of the Partnership's trading activities. A
forward contract is  a contractual obligation  to purchase or  sell a  specified
quantity  of a commodity at a specified date  in the future at a specified price
and, therefore, is similar to a futures contract. However, forward contracts are
not traded on exchanges  and, as a consequence,  investors in forward  contracts
are  not  afforded the  regulatory protections  of such  exchanges or  the CFTC;
rather, banks and dealers  act as principals in  such markets. Neither the  CFTC
nor banking authorities regulate trading in forward contracts on currencies, and
foreign banks may not be regulated by any United States governmental agency.
    
 
    Generally,  when a Trading Advisor instructs  the Partnership to either sell
or buy a particular currency or other forward contract, DWR will do back-to-back
principal trades in  order to carry  out such instructions.  DWR, as  principal,
will  arrange bank lines of credit and  contract with a United States or foreign
bank or  dealer to  make or  take future  delivery of  a specified  quantity  of
currency or other commodity at a negotiated price. DWR, again as principal, will
in  turn contract with  the Partnership to  make or take  future delivery of the
same specified quantity of  currency or other commodity  at the same price.  DWR
will  charge the Partnership a transaction  fee for effecting a forward contract
transaction, but will not attempt  to profit from any  mark-up or spread on  the
trade with the Partnership.
 
    Because performance of forward contracts on currencies and other commodities
is  not guaranteed by any exchange  or clearinghouse, the Partnership is subject
to the  risk  of the  inability  or refusal  to  perform with  respect  to  such
contracts  on the  part of the  principals or  agents with or  through which the
Partnership trades. Currently  the sole counterparty  with whom the  Partnership
trades  is  DWR.  Any  such  failure  or  refusal,  whether  due  to insolvency,
bankruptcy or other causes, could subject the Partnership to substantial losses.
The Partnership and DWR will trade  forward contracts only with banks,  brokers,
dealers   and  other  financial  institutions  which  the  General  Partner,  in
conjunction with DWR, has determined to be creditworthy.
 
    The CFTC has published for comment  in the United States Federal Register  a
statement  concerning its jurisdiction over transactions in the foreign currency
markets, including  transactions of  the type  which may  be engaged  in by  the
Partnership.  In the future, the CFTC might assert that forward contracts of the
type entered into by the  Partnership constitute unauthorized futures  contracts
subject  to the CFTC's jurisdiction and attempt to prohibit the Partnership from
participating in  transactions  in  such  contracts.  If  the  Partnership  were
restricted  in  its  ability  to  trade in  the  currency  markets,  the trading
strategies of the Trading Advisors could be materially affected.
 
   
    SPECIAL RISKS ASSOCIATED WITH TRADING ON FOREIGN EXCHANGES.  The Partnership
trades in futures, forward,  and option contracts  on exchanges located  outside
the   United  States  where  CFTC  regulations   do  not  apply.  Based  on  the
Partnership's trading from August 1991 through August 1996 and the allocation of
assets among the Trading Advisors, trading on foreign exchanges is expected  to,
on   average,  comprise  approximately  25-30%   of  the  Partnership's  trading
activities. Some  foreign  exchanges, in  contrast  to domestic  exchanges,  are
"principals'  markets" in  which performance with  respect to a  contract is the
responsibility only of the  individual member with whom  the trader has  entered
into a contract and not of the exchange or clearinghouse, if any. In the case of
trading on foreign exchanges, the Partnership will be subject to the risk of the
inability  of, or refusal by,  the counterparty to perform  with respect to such
contracts. Although DWR monitors the  creditworthiness of the foreign  exchanges
and  clearing brokers with which it does business for clients, DWR does not have
the
    
 
                                       14
<PAGE>
capability to precisely quantify the Partnership's exposure to risks inherent in
its trading activities on foreign  exchanges, and as a  result, the risk is  not
monitored by DWR on an individual client basis (including the Partnership).
 
    Trading  on foreign exchanges may involve certain other risks not applicable
to trading on United States exchanges,  such as the risks of exchange  controls,
expropriation, burdensome or confiscatory taxation, moratoriums, or political or
diplomatic events. In addition, certain foreign markets are newly formed and may
lack  personnel  experienced in  floor trading  as well  as in  monitoring floor
trades for compliance with exchange rules.
 
    Furthermore, as the Partnership determines  its Net Assets in United  States
dollars,  with respect to trading on  foreign markets the Partnership is subject
to the risk of fluctuation in the  exchange rate between the local currency  and
dollars,  and to  the possibility of  exchange controls.  Unless the Partnership
hedges itself against fluctuations in  exchange rates between the United  States
dollar  and the currencies in  which trading is done  on such foreign exchanges,
any profits  which  the Partnership  might  realize  in such  trading  could  be
eliminated as a result of adverse changes in exchange rates, and the Partnership
could  even incur  losses as  a result  of any  such changes.  See "The Futures,
Options and Forward Markets--Regulations."
 
    SPECIAL RISKS ASSOCIATED  WITH TRADING OF  OPTIONS ON FUTURES.   Options  on
futures  contracts  and options  on physical  commodities  are traded  on United
States commodity  exchanges and  may be  traded by  the Partnership  on  certain
foreign  exchanges. The Partnership  is authorized to trade  options and some of
the Trading Advisors have included options in their trading. Each such option is
a right, purchased for  a certain price,  to either buy  or sell the  underlying
futures  contract or physical  commodity during a  certain period of  time for a
fixed price. Such trading involves risks substantially similar to those involved
in trading  futures  contracts  in  that  options  are  speculative  and  highly
leveraged.  Specific  market movements  of  the underlying  futures  contract or
physical commodity cannot be accurately predicted. The purchaser of an option is
subject to the  risk of  losing the  entire purchase  price of  the option.  The
writer of an option is subject to the risk of loss resulting from the difference
between  the premium received for  the option and the  price of the commodity or
futures contract underlying the option which the writer must purchase or deliver
upon  exercise  of  the   option.  See  "The   Futures,  Options,  and   Forward
Markets--Options on Futures."
 
    THE  PARTNERSHIP HAS CREDIT  RISK TO DWR.   The Partnership  has credit risk
because DWR acts  as the futures  commission merchant or  the sole  counterparty
with  respect  to  most of  the  Partnership's assets.  Exchange  traded futures
contracts are  marked to  market on  a  daily basis,  with variations  in  value
credited  or charged  to the  Partnership's account  on a  daily basis.  DWR, as
futures commission  merchant  for  the  Partnership's  exchange  traded  futures
contracts,  is required, pursuant to CFTC regulations, to segregate from its own
assets, and for the sole benefit of  its commodity customers, all funds held  by
DWR with respect to exchange traded futures contracts, including an amount equal
to  the net unrealized gain  on all open futures  contracts. With respect to the
Partnership's off-exchange traded foreign currency forward contracts, there  are
no  daily settlements of  variations in value.  See "Management's Discussion and
Analysis of  Financial Condition  and Results  of Operations--Off-Balance  Sheet
Risk."
 
    POSSIBLE  EFFECTS OF SPECULATIVE  POSITION LIMITS.  The  CFTC and the United
States futures exchanges  have established  limits referred  to as  "speculative
position  limits" or  "position limits"  on the  maximum net  long or  net short
futures or options contract  position which any person  or group of persons  may
own, hold, or control in particular futures or options contract.
 
    All futures and option accounts owned, controlled or managed by each Trading
Advisor  and its principals will be combined for position limit purposes, to the
extent they may  be applicable.  In this connection,  the Management  Agreements
provide that if speculative position limits are exceeded by a Trading Advisor in
the  opinion of independent counsel, the  CFTC or any regulatory body, exchange,
or board, such Trading Advisor and  its principals and affiliates will  promptly
liquidate  positions  in  all  of their  accounts,  including  the Partnership's
account,   as   to   which   positions    are   attributed   to   the    Trading
 
                                       15
<PAGE>
Advisor, as nearly as possible in proportion to the accounts' respective amounts
available  for trading  (taking into account  different degrees  of leverage and
"notional equity") to the  extent necessary to  comply with applicable  position
limits.  See "The Management Agreements." Rabar and EMC believe that established
position limits,  where  applicable,  restrict their  contemplated  trading  for
clients, including the Partnership, and, from time to time, the trading approach
or  instructions of  the Trading  Advisors for  the Partnership  may have  to be
modified, and positions held  by the Partnership may  have to be liquidated,  in
order  to  avoid exceeding  such limits.  Such  modification or  liquidation, if
required, could  adversely  affect  the  operations  and  profitability  of  the
Partnership.  See "Conflicts of  Interest-- Management of  Other Accounts by the
Trading Advisors."  The Partnership  is  also subject  to the  same  speculative
position  limits and may  have to modify  or liquidate positions  if such limits
are, or are about  to be, exceeded  by the Partnership  as a whole.  Speculative
position  limits are  not applicable to  forward contract  trading, although the
principals with which DWR or the Partnership may deal in the forward markets may
limit the positions  available to  DWR or the  Partnership as  a consequence  of
credit considerations.
 
RISKS RELATING TO THE PARTNERSHIP AND THE OFFERING OF UNITS
 
    PAST  RESULTS NOT  NECESSARILY INDICATIVE OF  FUTURE PERFORMANCE.   The past
performance  results  of  the  Partnership  (see  "Performance  Record  of   the
Partnership"),  are not necessarily indicative of  the future performance of the
Partnership.
 
    SUBSTANTIAL CHARGES  TO THE  PARTNERSHIP.   The  Partnership is  subject  to
substantial charges to its Net Assets from the payment of the monthly management
fee,  brokerage commissions,  other transaction  fees and  costs, administrative
expenses, and any  extraordinary costs,  regardless of  whether the  Partnership
realizes  profits. For  the years  ended December 31,  1995, 1994  and 1993, the
Partnership had  total revenues  of  $69,299,562, $17,420,402  and  $42,931,325,
respectively,  and total expenses of  $30,245,447, $27,233,309, and $16,539,113,
respectively. Because the incentive fee which  the Partnership will pay to  each
Trading  Advisor will  be determined  on a  quarterly rather  than on  an annual
basis, the Partnership may be subject to substantial incentive fees in any given
12 consecutive month period  despite a decline in  the Partnership's Net  Assets
for  such period as a whole. Moreover, because incentive fees are determined and
paid separately for each Trading Advisor, the Partnership may be required to pay
an incentive fee to one or two Trading Advisors in any given quarter due to  the
Trading  Profits experienced by  such Trading Advisors'  allocated Net Assets in
spite of losses or lack of any Trading Profits experienced by one or both of the
other Trading Advisors' allocated Net Assets or by the Partnership's Net  Assets
as a whole. See "Description of Charges to the Partnership."
 
    RESTRICTED  INVESTMENT LIQUIDITY IN THE UNITS.  The Units cannot be assigned
or transferred  except on  the terms  and conditions  set forth  in the  Limited
Partnership  Agreement, and there  will be no  public market for  the Units. See
"The Limited Partnership Agreement--Restrictions on Transfers or Assignments." A
Limited Partner, after proper notice has been given, may require the Partnership
to redeem all or part  of his Units as of,  but not before, the sixth  month-end
following  the closing at which such person  first becomes a Limited Partner, in
the manner described herein. Thereafter, Units may be redeemed as of the end  of
any  month. However,  no Limited Partner  may redeem fractions  of Units, except
that fractions of Units  may be redeemed  if a Limited  Partner is redeeming  in
multiples  of $1,000  or is  redeeming his  entire interest  in the Partnership.
Redemptions of Units are subject to redemption charges through the twenty-fourth
full month following the closing at  which such Units are issued. The  foregoing
redemption  charges  and the  six  month limitation  will  not apply  to Limited
Partners who purchase  Units pursuant  to Exchanges. An  investor who  purchases
$500,000  or  more  of Units  will  not  be subject  to  the  redemption charges
described above. The right  to obtain payment on  redemption is contingent  upon
(a) the Partnership having assets sufficient to discharge its liabilities on the
effective  date of  the redemption,  and (b) the  timely receipt  by the General
Partner of a  Request for  Redemption. All  liabilities of  the Partnership  are
accrued daily and are reflected in the daily Net Asset Value of the Partnership.
See  "Redemptions." Under certain circumstances  (including, but not limited to,
the Partnership's inability to liquidate or a delay in liquidating positions  or
the  default or  delay in  payments due  the Partnership  from dealers, brokers,
banks, or other persons), the Partnership may
 
                                       16
<PAGE>
delay payment to  Limited Partners requesting  redemptions of the  proportionate
part of the redemption requests represented by the sums which are the subject of
any such default or delay. See "Redemptions."
 
    CONFLICTS  OF INTEREST  IN THE PARTNERSHIP  STRUCTURE.  DWR  and the General
Partner were instrumental  in the  organization of  the Partnership  and may  be
deemed  "promoters" of the Partnership within the  meaning of Rule 405 under the
Securities Act of 1933, as amended (the "1933 Act"). Moreover, the  Partnership,
DWR  and the General  Partner are affiliated  entities and are  represented by a
single counsel.  As a  consequence of  the  foregoing, there  is an  absence  of
arm's-length negotiation with respect to some of the terms of this offering. See
"Conflicts of Interest."
 
    LIMITED  PARTNERS WILL NOT PARTICIPATE IN MANAGEMENT.  Limited Partners will
not participate in the management  of the Partnership or  in the conduct of  its
business.  See  "The  Limited Partnership  Agreement--Management  of Partnership
Affairs." However,  the  Limited  Partnership Agreement  provides  that  certain
actions  may be taken upon the affirmative  vote of Limited Partners owning more
than 50%  of  the  Units  then  owned by  Limited  Partners.  See  "The  Limited
Partnership Agreement--Amendments; Meetings."
 
    RELIANCE  ON  THE GENERAL  PARTNER.   A  Limited Partner  is relying  on the
ability of the  General Partner to  select successful Trading  Advisors for  the
Partnership.  The  selection  by the  General  Partner of  the  Trading Advisors
involved numerous considerations. The General Partner evaluated the  performance
record  of  each  Trading Advisor  and  determined which  Trading  Advisors were
suitable for the  Partnership's overall trading  approach, trading policies  and
investment  objectives.  The  General  Partner reviewed  other  aspects  of each
Trading Advisor  (including the  prospective Trading  Advisor's trading  system,
experience,   volatility  of  trading,  futures   interests  traded,  amount  of
management and  incentive  fees  normally charged,  reputation  of  the  Trading
Advisor  and  its personnel  and  amount of  funds  under management),  and made
certain subjective judgments in retaining Trading Advisors for the  Partnership.
Although  the General Partner carefully weighed  the above factors in making its
selections, other factors  not considered  by the  General Partner  may also  be
important.  In the future, the General Partner  may be required to terminate and
replace a Trading Advisor by reason of its poor performance or for other reasons
or to  retain  additional  Trading  Advisors for  the  Partnership  and  similar
judgments will have to be made from time to time.
 
RISKS RELATING TO THE TRADING ADVISORS
 
    RELIANCE  ON THE TRADING ADVISORS TO  TRADE SUCCESSFULLY.  Futures interests
trading decisions for the Partnership will be made by the Trading Advisors, upon
whose judgment and abilities the success of the Partnership will largely depend.
No assurance can  be given that  the respective trading  systems and  strategies
utilized  by the Trading Advisors will prove  successful under all or any market
conditions.
 
    MARKET FACTORS MAY ADVERSELY INFLUENCE TRADING STRATEGIES.  Any factor which
may lessen the prospect  of major trends in  the future (for example,  increased
governmental control of, or participation in, the currency markets) may reduce a
Trading  Advisor's ability to  trade profitably in the  future. Any factor which
would make it  more difficult to  execute timely trades,  such as a  significant
lessening  of liquidity  in a  particular market,  would also  be detrimental to
profitability. As a result  of these factors and  the general volatility of  the
futures  interests markets, investors should view  their investment as long term
(at least 2 years) in order to permit the strategies of the Trading Advisors  to
function  over time.  Further, a Trading  Advisor may alter  its strategies from
time to time in an attempt to  better evaluate market movements. As a result  of
such  periodic modifications, it is possible that the trading strategies used by
a Trading Advisor in the future may be different from those presently in use.
 
    LIMITED TERM  OF  MANAGEMENT  AGREEMENTS  MAY  LIMIT  ACCESS  TO  A  TRADING
ADVISOR.   The Management Agreements with  the Trading Advisors will continue in
effect for two  years from the  date of First  Closing. Thereafter, the  Trading
Advisors  may  terminate the  Management Agreements  on  30 days'  prior written
notice to the Partnership. In addition, each Management Agreement is  terminable
by  the Partnership at any time without penalty on 15 days' prior written notice
and in certain other
 
                                       17
<PAGE>
circumstances, and  is terminable  by the  Trading Advisors  at any  time  under
certain  circumstances. See "The Management  Agreements." Upon the expiration or
termination of  a Management  Agreement,  the General  Partner will  make  other
arrangements  for  providing trading  advice. In  the  selection of  any trading
advisor upon the termination of a Management Agreement (including any  retention
of a Trading Advisor thereafter), the General Partner will take into account all
relevant   factors,   including  the   prospective  trading   advisor's  trading
performance, experience, volatility of trading, futures interests traded, amount
of management and  incentive fees  normally charged, reputation  of the  trading
advisor  and its personnel and amount of  funds under management, as well as the
trading policies and investment objectives of  the Partnership. There can be  no
assurance  that the services of a trading  advisor will be available on the same
or similar terms in case of expiration or termination of a Management Agreement.
 
    USING MULTIPLE  TRADING  ADVISORS  MAY ADVERSELY  AFFECT  THE  PARTNERSHIP'S
PERFORMANCE.   The Trading  Advisors make trading  decisions for the Partnership
independent of each other. Thus, there  is the possibility that the  Partnership
could  hold opposite positions in  the same or similar  futures interests at the
same time or during the same period of time, with no net change in its holdings.
The General  Partner  has  not  undertaken to  determine  if  such  trading  has
occurred,  or is likely to occur, or  its potential effect on performance. There
is also the possibility that EMC, Rabar, and Sunrise may from time to time enter
identical orders  for futures  interests and,  therefore, compete  for the  same
trades.  Such competition  could prevent orders  for the  Partnership from being
executed at desired prices.
 
   
    ALLOCATION OF THE PARTNERSHIP'S  NET ASSETS AMONG  THE TRADING ADVISORS  MAY
ADVERSELY AFFECT THE PARTNERSHIP'S PERFORMANCE.  The General Partner anticipates
allocating  the proceeds from  the sale of  Units at each  closing equally among
EMC, Rabar, and Sunrise.  The General Partner  may reallocate the  Partnership's
Net  Assets among the  Trading Advisors (including  any newly-designated trading
advisors) in  such  amounts  as  the General  Partner  determines  in  its  sole
discretion. Also, as a result of the performance of each of the Trading Advisors
since  the commencement of trading by  the Partnership, the allocations for each
Trading Advisor are not  equal. This may affect  the performance results of  the
Partnership.  For example, a Trading Advisor  may experience a high monthly rate
of return but may only be managing  a small percentage of the Partnership's  Net
Assets  and the  Net Asset  Value of  a Unit.  Alternatively, a  Trading Advisor
experiencing such a rate  of return may  be managing a  large percentage of  the
Partnership's  Net Assets and such performance  may have a significant affect on
the Partnership's Net Assets and the Net Asset Value of a Unit. As of August 31,
1996, EMC was trading  approximately 26%, Rabar  was trading approximately  42%,
and Sunrise was trading approximately 32% of the Partnership's assets.
    
 
    Although  each Trading Advisor's margin and option premium requirements will
be charged  against  such Trading  Advisor's  allocated Net  Assets,  a  Trading
Advisor  may incur  losses of such  magnitude that  it is unable  to meet margin
calls from its allocated Net Assets. If this occurs, the General Partner may  be
required to reallocate Net Assets among the Trading Advisors and may be required
to  take Net Assets from the more  successful Trading Advisors to satisfy margin
requirements attributable  to  trading  directed  by  the  unsuccessful  Trading
Advisor.  This  could adversely  affect the  performance  of such  other Trading
Advisors and the  Partnership. See  "The Trading Advisors"  and "The  Management
Agreements--Allocation and Reallocation of the Partnership's Net Assets."
 
    POSSIBLE  ADVERSE EFFECTS  OF INCREASING  THE ASSETS  TRADED BY  THE TRADING
ADVISORS.  A  trading advisor is  limited in the  amount of assets  that it  can
successfully  manage, both by  the difficulty of  executing substantially larger
trades made necessary by the larger amount of equity under management and by the
restrictive effect of  speculative position limits.  Increased equity  generally
results  in a larger  demand for the  same futures interests  among the accounts
managed by  a trading  advisor. Furthermore,  while there  has been  substantial
debate  on the subject, a considerable number of analysts believe that a trading
advisor's rate  of  return tends  to  decrease as  the  amount of  equity  under
management  increases. The Trading Advisors have  not agreed to limit the amount
of additional equity that they  may manage. There can  be no assurance that  the
Trading  Advisors' respective trading systems will  not be adversely affected by
additional equity, including the proceeds of this offering.
 
                                       18
<PAGE>
    TRADING DECISIONS BASED ON TECHNICAL TRADING APPROACH MAY NOT PERFORM  UNDER
CERTAIN  MARKET CONDITIONS.  Trading decisions of the Trading Advisors are based
on "technical"  trading systems  as opposed  to "fundamental"  trading  methods.
Fundamental  trading  methods  attempt  to  examine  external  factors  (such as
governmental policies, national and international political and economic events,
changing trade prospects, and similar factors which affect the supply and demand
for a particular futures interest) in order to predict future prices.  Technical
trading  systems, however, generate buy and sell  signals which are not based on
analysis of fundamental supply and demand factors, but rather are based, in most
cases, upon a  study of actual  daily, weekly, and  monthly price  fluctuations,
volume  variations and changes in open  interest and other related mathematical,
statistical or quantitative data utilizing charts and/or computers.
 
    The profitability  of both  technical and  fundamental analysis  in  futures
interests trading generally depends upon the accurate forecasting of major price
moves  or trends  in some futures  interests. No  assurance can be  given of the
accuracy of the forecasts or  the existence of some  major price move. The  best
trading  approach will not be profitable if there are sustained periods in which
there are no price  moves or trends  of the kind the  trading approach seeks  to
identify  and follow. In  the past, there have  been periods without discernible
trends and,  presumably, such  periods will  continue to  occur in  the  future.
Periods  without such  price moves  may produce  losses. Any  factor which would
lessen the prospect of major trends  occurring in the future (such as  increased
governmental control of or participation in the markets) may reduce the prospect
that  a particular trading approach will  be profitable in the future. Moreover,
any factor  which would  make it  more difficult  to execute  trades at  desired
prices in accordance with a trading approach (such as a significant lessening of
liquidity  in a particular  market) would also  be detrimental to profitability.
Many other  trading  approaches  utilize  similar  analyses  in  making  trading
decisions;  therefore, bunching of buy and sell  orders can occur which makes it
more difficult for a  position to be  taken or liquidated.  No assurance can  be
given  that  the  Trading  Advisors'  respective  trading  systems  and  trading
decisions will be successful under all or any market conditions.
 
    A limiting factor in the use of technical analysis is that such an  approach
generally requires price movement data which can be translated into price trends
sufficient  to dictate  a market  entry or  exit decision.  Any trading approach
which is based upon  such technical concepts may  not perform well when  futures
interests  markets are  trendless or erratic,  because a  technical approach may
fail to identify  a trend on  which action should  be taken or  it may react  to
minor  price movements and  thus establish a position  contrary to overall price
trends, which may result  in losses. In addition,  a technical trading  approach
may  underperform  other trading  approaches  when fundamental  factors dominate
price moves  within  a  given  market. For  example,  since  technical  analysis
generally does not take into account fundamental factors such as supply, demand,
and  political  and economic  events (except  insofar as  such factors  may have
influenced price and  other technical  data constituting  input information  for
such  approach),  a  technical trading  approach  may  be unable  to  respond to
fundamental causative events until  after their impact  has ceased to  influence
the  markets;  positions  dictated  by such  resultant  price  movements  may be
incorrect in light of the fundamental factors then affecting the markets.
 
    The calculations  which  underlie  the  Trading  Advisors'  trading  systems
involve  many  variables and  are  determined, in  the  case of  Rabar  and EMC,
primarily by  computer. The  use of  a computer  in developing  and operating  a
trading  system does not assure the success  of the system because a computer is
merely an aid in compiling and  organizing trading information. No assurance  is
given  that the respective  trading strategies employed  by the Trading Advisors
will produce profits or will not lose money.
 
    POSSIBLE EFFECTS  OF  OTHER  TREND-FOLLOWING  SYSTEMS.    Futures  interests
trading  systems employing trend-following signals,  based either exclusively on
technical analysis or on  a combination of  fundamental and technical  analysis,
are  not new. If many traders follow  very similar systems, similar buy and sell
orders can be placed at  or about the same time,  which makes it more  difficult
for  a position to  be established or  liquidated at a  given price. The General
Partner is aware of an  increase in both the  use of trend-following systems  in
recent  years and in the overall volume  of trading and liquidity of the futures
interests markets. However,  it is  difficult to  be certain  whether the  total
amount of funds traded
 
                                       19
<PAGE>
on  a trend-following basis,  either for futures  contracts as a  whole or for a
particular futures interests, is greater in proportion to the overall volume and
liquidity of markets presently  than has been  the case in  the past. While  the
effect  of  any  increase  in  the  proposition  of  funds  traded  pursuant  to
trend-following systems in recent years cannot be determined, any such  increase
could  alter trading patterns or affect execution  of trades to the detriment of
the Partnership.
 
TAXATION AND REGULATORY RISKS
 
    POSSIBILITY OF TAXATION  AS A  CORPORATION.   The General  Partner has  been
advised  by its legal counsel, Cadwalader, Wickersham & Taft, that under current
United States federal  income tax  (hereinafter "federal income  tax") laws  and
regulations,  the Partnership will be classified as  a partnership and not as an
association taxable as a  corporation. This status has  not been confirmed by  a
ruling  from, and such  advice is not  binding upon, the  United States Internal
Revenue Service (the  "Internal Revenue Service").  No such ruling  has been  or
will  be requested. The  facts and authorities  relied upon by  counsel in their
opinion may change in the future. If the Partnership were taxed as a corporation
for federal income tax purposes, income or loss of the Partnership would not  be
passed  through to Partners and  the Partnership would be  subject to tax on its
income at the rates  of tax applicable to  corporations, without any  deductions
for   distributions  to  the  Partners.  In   addition,  all  or  a  portion  of
distributions made to the Partners could be taxable to the Partners as dividends
or capital gains. See "Material Federal Income Tax Considerations."
 
    PARTNER'S TAX LIABILITY MAY  EXCEED DISTRIBUTIONS.   If the Partnership  has
profits  for a  taxable year,  such profit  will be  taxable to  the Partners in
accordance with their distributive shares of Partnership profit, whether or  not
the  profit actually  has been distributed  to the  Partners. Accordingly, taxes
payable by Partners with respect to Partnership profit may exceed the amount  of
Partnership  distributions, if any, for a taxable year. Further, the Partnership
may sustain losses offsetting such profit in a succeeding taxable year, so  that
Partners  may never  receive the profit  on which  they were taxed  in the prior
year. See "Material Federal Income Tax Considerations."
 
    POSSIBLE LIMITATION ON DEDUCTION OF CERTAIN EXPENSES.  The deductibility  of
certain miscellaneous itemized deductions is limited to the extent such expenses
exceed  2% of the  adjusted gross income  of an individual,  trust or estate. In
addition, certain of an individual's itemized deductions are further reduced  by
an  amount equal  to the lesser  of (i)  3% of such  individual's adjusted gross
income over a certain threshold amount and (ii) 80% of such itemized deductions.
Based upon  the activities  of the  Partnership, the  General Partner  has  been
advised  by its legal counsel that  various expenses incurred by the Partnership
should not  be  subject to  these  limitations except  to  the extent  that  the
Internal  Revenue Service promulgates regulations that so provide. See "Material
Federal Income Tax Considerations."
 
    POSSIBILITY OF TAX AUDIT.  There can be no assurance that the  Partnership's
tax  return  will  not  be  audited by  the  Internal  Revenue  Service  or that
adjustments to such return will not be made as a result of such an audit. If  an
audit results in an adjustment, Limited Partners may be required to file amended
returns  (which  may themselves  also be  audited)  and to  pay back  taxes plus
interest and/or penalties that may then be due. See "Material Federal Income Tax
Considerations."
 
    ABSENCE OF  REGULATIONS  APPLICABLE TO  SECURITIES  MUTUAL FUNDS  AND  THEIR
ADVISERS.   The  Partnership is  not registered  as an  investment company  or a
"mutual fund"  under the  Investment Company  Act of  1940, as  amended (or  any
similar  state law), and neither the General  Partner nor any Trading Advisor is
registered as an investment adviser under  the Investment Advisers Act of  1940,
as  amended (or any  similar state law). Investors,  therefore, are not accorded
the protective measures  provided by  such legislation.  However, in  accordance
with the provisions of the Commodity Exchange Act, as amended (the "CEAct"), the
regulations  of the CFTC  thereunder and the  NFA rules, the  General Partner is
registered as a commodity pool operator, the Trading Advisors are registered  as
commodity  trading  advisors,  and DWR  is  registered as  a  futures commission
merchant, each subject to regulation by the CFTC and each a member of the NFA in
such respective capacities.
 
    THE FOREGOING RISK FACTORS  DO NOT PURPORT TO  BE A COMPLETE EXPLANATION  OF
ALL  THE RISKS INVOLVED  IN THIS OFFERING. POTENTIAL  INVESTORS SHOULD READ THIS
PROSPECTUS IN ITS ENTIRETY BEFORE DETERMINING WHETHER TO INVEST IN THE UNITS.
 
                                       20

                             CONFLICTS OF INTEREST
 
RELATIONSHIP OF THE GENERAL PARTNER TO THE COMMODITY BROKER
 
   
    The  General Partner is a wholly-owned subsidiary of Dean Witter, Discover &
Co. ("DWD"), a principal subsidiary of which, DWR, acts as the commodity  broker
for,  and receives  brokerage commissions  from, the  Partnership pursuant  to a
Customer Agreement.  Because the  General Partner  is affiliated  with DWR,  the
General Partner will have a conflict of interest between its responsibilities to
limit and reduce the brokerage commissions paid by the Partnership and otherwise
manage  the Partnership for the benefit of the Limited Partners and its interest
in obtaining for DWR favorable brokerage commissions. Most customers of DWR  who
maintain   commodity  trading  accounts  over   $1,000,000  pay  commissions  at
negotiated rates which are substantially less than the rate which is paid by the
Partnership. Four of the 22 currently actively trading commodity pools for which
Demeter acts  as general  partner are  charged flat-rate  asset based  brokerage
fees,  16 of  such commodity  pools are  charged brokerage  fees on  a roundturn
brokerage commission basis (I.E., a charge for entering and exiting each futures
interest transaction) and such  fees are subject to  a monthly asset-based  cap,
and  two are charged on a roundturn brokerage commission basis without a monthly
asset-based cap. See "The Commodity Broker" and "Fiduciary Responsibility."
    
 
    The General Partner selected  the Trading Advisors  and will participate  in
the  selection of any new trading  advisor for the Partnership. However, because
the selection of trading  advisors who engage  in a high  volume of trades  will
increase the costs to DWR of serving as commodity broker for the Partnership (if
commissions   for  any  month   exceed  the  asset-based   cap  described  under
"Description of  Charges  to the  Partnership"),  without DWR's  receipt  of  an
offsetting  increase in revenue, the General  Partner has an incentive to select
trading advisors who  engage in  a volume  of trades  which generate  commission
revenue up to, but not exceeding the cap.
 
    In  addition, the  Partnership, DWR and  the General  Partner are affiliated
entities and  are represented  by a  single  counsel. As  a consequence  of  the
foregoing,  there is an absence of arm's-length negotiation with respect to some
of the terms of this offering.
 
    While the Customer Agreement  is nonexclusive, so  that the Partnership  has
the  right to seek  lower commission rates  from other brokers  at any time, the
General Partner  believes that  the Customer  Agreement and  other  arrangements
between  the  Partnership  and DWR  are  fair, reasonable  and  competitive, and
represent the  best  prices  and services  available,  considering  the  matters
discussed in this paragraph below and in the immediately following paragraph. In
addition   to  DWR's  cost  of  executing   futures  interests  trades  for  the
Partnership, DWR is subject to the risk  and expense of offering the Units,  and
the  General Partner, an affiliate of DWR,  will provide ongoing services to the
Partnership, which  include  administering  the redemption  of  Units,  and  the
General  Partner  has  financial  obligations  as  the  general  partner  of the
Partnership. A significant portion  of the brokerage commissions  to be paid  to
DWR  by the  Partnership will  be paid by  DWR to  certain of  its employees for
providing continuing  assistance to  Limited  Partners to  whom they  have  sold
Units.  Such DWR employees who provide  continuing advice to Limited Partners as
to when and whether to redeem Units may have a conflict of interest by reason of
their continuing receipt of a portion  of the brokerage commissions paid to  DWR
by the Partnership.
 
    The General Partner will review the brokerage arrangements at least annually
to ensure they are fair, reasonable and competitive, and that they represent the
best  price  and  services available,  taking  into consideration  the  size and
trading activity  of  the Partnership  and  the services  provided,  and  costs,
expenses,  and risk borne,  by DWR and  the General Partner.  See "The Commodity
Broker" and "Fiduciary Responsibility."
 
    The Partnership trades in forward contracts through DWR. The General Partner
has a conflict  of interest in  selecting its  affiliate as the  party with  and
through  which the Partnership  executes its forward  trades and selecting other
persons which  might  be able  to  make a  better  price or  superior  execution
available  to the Partnership. The General Partner will review the Partnership's
forward
 
                                       21
<PAGE>
trading arrangements from time to time  in an attempt to determine whether  such
arrangements  are competitive with  those of other comparable  pools in light of
the circumstances.  See  "Risk Factors--  Risks  Relating to  Futures  Interests
Trading and the Futures Interests Markets--Special Risks Associated with Forward
Trading" and "The Futures, Options and Forward Markets."
 
    DWR  and  the  General  Partner  may,  from  time  to  time,  be  subject to
conflicting demands in respect of their obligations to the Partnership and other
commodity pools  and  accounts.  Certain pools  may  generate  larger  brokerage
commissions  to  DWR,  resulting  in  increased  payments  to  DWR  employees as
described above. Since DWR employees  may receive greater compensation from  the
sale of units of one pool over another, such employees are subject to a conflict
of interest in providing advice to Limited Partners.
 
ACCOUNTS OF AFFILIATES OF THE GENERAL PARTNER, THE TRADING ADVISORS AND DWR
 
    While  the  General Partner  does not  trade futures  interests for  its own
account (other  than indirectly  as a  consequence of  its position  as  general
partner  of commodity pools),  certain officers, directors  and employees of the
General  Partner,  and  the  Trading   Advisors,  DWR,  and  their   affiliates,
principals,  directors, officers, and employees, may trade futures interests for
their own accounts. The records of such trading will not be available to Limited
Partners. In  addition, DWR  is a  large futures  commission merchant,  handling
substantial customer business in physical commodities and futures interests, and
is  a clearing  member of  all of  the major  commodity exchanges  in the United
States. It is possible that DWR will effect transactions for the Partnership  in
which  the  other party  to such  transactions  is an  employee of  or otherwise
affiliated with  the General  Partner, DWR,  or their  affiliates. Such  persons
might  also compete  with the  Partnership in bidding  on purchases  or sales of
futures interests without knowing  that the Partnership is  also bidding. It  is
possible  that transactions for the  officers, directors, affiliates, employees,
customers and  correspondents of  DWR, the  General Partner  or certain  of  the
Trading  Advisors might be effected when  similar trades for the Partnership are
not executed or are executed at  less favorable prices. In addition, certain  of
the officers and directors of the General Partner (who are also employees of and
are  compensated  by the  Commodity Broker)  may  individually receive  from DWR
compensation  and  bonuses  based   on  various  factors,  including   brokerage
commissions  generated by  the Partnership. See  "The General  Partner" and "The
Commodity Broker."
 
    The Limited Partnership Agreement provides that, except as described therein
or in  this Prospectus,  no  person may  receive,  directly or  indirectly,  any
advisory,  management,  or incentive  fee for  investment  advice who  shares or
participates  in  per  trade  commodity   brokerage  commissions  paid  by   the
Partnership.  No  commodity  broker for  the  Partnership may  pay,  directly or
indirectly, rebates or "give ups" to the General Partner or any trading advisor,
and such  prohibitions  may  not  be circumvented  by  any  reciprocal  business
arrangements.
 
MANAGEMENT OF OTHER ACCOUNTS BY THE TRADING ADVISORS
 
    Each  Management  Agreement allows  the  Trading Advisor  to  manage futures
interests accounts  in  addition  to the  Partnership's  account.  Each  Trading
Advisor  and its principals and affiliates may  at any time be trading their own
proprietary  accounts,  advising  accounts  for  other  commodity  pools  and/or
individual  customers and operating other commodity pools and will continue such
activities in  the future.  Some Trading  Advisors may  also operate  additional
trading  systems or use other trading  programs in their management of accounts,
some of  which  systems  and  programs  may not  be  used  in  trading  for  the
Partnership.  Such other trading systems have in  the past and may in the future
experience significantly different performance results than the systems used  in
trading  for the  Partnership. The  Trading Advisors  are required  to aggregate
futures and option positions in other accounts managed by them with futures  and
option  positions in  the Partnership's  account for  speculative position limit
purposes. Such  aggregation of  positions  could require  a Trading  Advisor  to
liquidate  or modify  positions for all  such accounts, and  such liquidation or
modification may adversely affect the Partnership. A Trading Advisor may have  a
conflict  of interest in rendering advice  because its compensation for managing
some other accounts may exceed  its compensation for managing the  Partnership's
account,  and therefore may  provide an incentive to  favor such other accounts.
Moreover, if a Trading
 
                                       22
<PAGE>
Advisor makes trading decisions for such accounts and the Partnership's  account
at  or about  the same time,  the Partnership  may be competing  with such other
accounts for the  same or similar  positions. While the  records of accounts  of
each  Trading Advisor's  employees and accounts  managed by  the Trading Advisor
will not  be  made available  to  Limited Partners,  each  Management  Agreement
permits  the General Partner access  to such records in  order to determine that
the Partnership's  account  is traded  fairly.  Each Management  Agreement  also
provides  that the Trading Advisor will deal with the Partnership in a fiduciary
capacity to the  extent recognized  by applicable law  and will  not enter  into
transactions  where it knowingly or deliberately favors itself or another client
over the Partnership.
 
CUSTOMER AGREEMENT WITH DWR
 
    The Partnership has established separate futures interests trading  accounts
with  DWR for each Trading Advisor pursuant  to the Customer Agreement with DWR.
Under  the  Customer   Agreement,  all  funds,   futures  interests   positions,
securities, and credits carried for the Partnership are held as security for the
Partnership's  obligations to DWR; the margins  required to initiate or maintain
open positions will  be as established  by DWR from  time to time;  and DWR  may
close out positions, purchase futures interests, or cancel orders at any time it
deems  necessary for its protection, without the consent of the Partnership. The
Partnership also has agreed  to indemnify and defend  DWR and its  stockholders,
employees,  officers,  directors  and  affiliates  against  certain  liabilities
incurred by them by reason of acting as the Partnership's commodity broker. DWR,
the General Partner or the Limited  Partners by majority vote may terminate  the
brokerage relationship and close the Partnership's futures interests accounts at
DWR  at any time upon  60 days' notice. If  so terminated, the Partnership would
have to negotiate a  new customer agreement with  a commodity broker upon  terms
and  conditions,  including  brokerage  commission rates,  which  cannot  now be
determined.
 
OTHER COMMODITY POOLS
 
    The General  Partner  is  or has  been  the  general partner  for  27  other
commodity  pools. DWR is the  commodity broker for such  pools and several other
commodity pools. Each may in the future establish and/or be the general  partner
or  commodity broker for  additional commodity pools,  and any such  pool may be
said to be in competition with the Partnership  in that any one or more of  such
pools might compete with the Partnership for the execution of trades.
 
                            FIDUCIARY RESPONSIBILITY
 
    Investors  should be  aware that  the General  Partner has  a fiduciary duty
under the Partnership  Act to the  Limited Partners to  exercise good faith  and
fairness  in  all  dealings  affecting the  Partnership.  The  General Partner's
fiduciary duty to the Limited  Partners under the Limited Partnership  Agreement
is  in accordance with the fiduciary duty  owed to limited partners by a general
partner under  Delaware law.  The Limited  Partnership Agreement  prohibits  the
Limited  Partners from limiting, by any means, the fiduciary duty of the General
Partner owed to the Limited Partners under statutory or common law. In the event
that a  Limited Partner  believes  that the  General  Partner has  violated  its
responsibilities,  the Limited Partner may seek legal relief for himself and all
other similarly situated Limited Partners or on behalf of the Partnership  under
the Partnership Act, the CEAct, applicable federal and state securities laws and
other  applicable laws to recover damages from,  or to require an accounting by,
the General Partner. The Trading  Advisors also have a fiduciary  responsibility
under applicable law to the Partnership.
 
    The   Limited  Partnership  Agreement,  the   Customer  Agreement,  and  the
Management Agreements  generally provide  that the  General Partner,  DWR,  each
Trading  Advisor and their  "affiliates" (as defined  in the Limited Partnership
Agreement) shall not be liable to the Partnership, the Limited Partners, its  or
their  successors  or  assigns,  for any  act,  omission,  conduct,  or activity
undertaken by or on behalf of the Partnership which the General Partner, DWR  or
the Trading Advisor, as applicable, determines, in good faith, to be in the best
interests of the Partnership, unless such act, omission, conduct, or activity of
or  by the  General Partner,  DWR, the Trading  Advisor or  their affiliates, as
applicable, constituted misconduct or negligence.
 
                                       23
<PAGE>
    The Limited  Partnership  Agreement,  the Customer  Agreement,  the  Selling
Agreement,  and the Management Agreements generally provide that the Partnership
will indemnify, defend, and hold harmless the General Partner, DWR, the  Trading
Advisors  and their  affiliates from  and against  any loss,  liability, damage,
cost, or  expense  (including  attorneys' and  accountants'  fees  and  expenses
incurred in defense of any demands, claims, or lawsuits) actually and reasonably
incurred  arising from acts, omissions, activities,  or conduct undertaken by or
on behalf  of  the  Partnership, including,  without  limitation,  any  demands,
claims,  or  lawsuits  initiated by  a  Limited Partner  (or  assignee thereof),
PROVIDED that (1) the General Partner, DWR, or a Trading Advisor, as applicable,
has determined,  in good  faith, that  the act,  omission, activity  or  conduct
giving  rise to the claim  for indemnification was in  the best interests of the
Partnership, and (2) the act, omission, activity, or conduct that was the  basis
for  such  loss, liability,  damage,  cost, or  expense  was not  the  result of
misconduct or  negligence.  Payment of  any  indemnity  to such  person  by  the
Partnership  would reduce the Net Assets of the Partnership. The General Partner
will not carry insurance covering such potential losses and the Partnership will
carry no liability insurance covering its potential indemnification exposure.
 
    Notwithstanding the foregoing, in any action brought by a Limited Partner in
the right of the Partnership, the  General Partner or any affiliate thereof  may
only be indemnified to the extent and subject to the conditions specified in the
Partnership  Act (which presently permits indemnification  of any partner to the
extent provided  in  the Limited  Partnership  Agreement, as  described  in  the
immediately  preceding  paragraph).  Also,  no  indemnification  of  the General
Partner, DWR, the Trading Advisors or their affiliates by the Partnership  shall
be permitted for losses, liabilities, or expenses arising from or out of alleged
violations  of federal  or state  securities laws unless:  (1) there  has been a
successful adjudication on the merits of each count involving alleged securities
law violations as  to the particular  indemnitee, or (2)  such claims have  been
dismissed  with prejudice on the merits by  a court of competent jurisdiction as
to the particular indemnitee, or (3) a court of competent jurisdiction  approves
a  settlement of  the claims  against the  particular indemnitee  and finds that
indemnification of the settlement  and related costs  should be made,  PROVIDED,
with regard to such court approval, the indemnitee must apprise the court of the
position   of  the  SEC,   and  the  positions   of  the  respective  securities
administrators of Massachusetts, Missouri,  Tennessee and/or those other  states
and jurisdictions in which the plaintiffs claim they were offered or sold Units,
with  respect to indemnification for  securities laws violations, before seeking
court approval for indemnification. Note  that, with respect to  indemnification
for   liabilities  arising  under  the  1933  Act  for  directors,  officers  or
controlling persons of the Partnership or the General Partner, it is the opinion
of the SEC that such indemnification  is against public policy, as expressed  in
the 1933 Act, and is therefore unenforceable. The CFTC has issued a statement of
policy  relating  to  indemnification of  officers  and directors  of  a futures
commission merchant (such as  DWR) and its controlling  persons under which  the
CFTC  has taken the position that  whether such an indemnification is consistent
with the policies expressed  in the CEAct  will be determined by  the CFTC on  a
case-by-case basis.

    "DRAWDOWN"  MEANS  DECLINE IN  NET ASSET  VALUE  PER UNIT.  "WORST MONTH-END
PEAK-TO-VALLEY  DRAWDOWN"  AS  USED  HEREIN  IS  EQUIVALENT  TO  THE  "DRAWDOWN"
EXPERIENCED BY THE PARTNERSHIP, DETERMINED IN ACCORDANCE WITH CFTC RULE 4.10 AND
REPRESENTS  THE GREATEST PERCENTAGE  DECLINE FROM ANY  MONTH-END NET ASSET VALUE
PER UNIT WHICH  OCCURS WITHOUT  SUCH MONTH-END NET  ASSET VALUE  PER UNIT  BEING
EQUALED  OR EXCEEDED AS OF A SUBSEQUENT MONTH-END. IN DOLLAR TERMS, FOR EXAMPLE,
IF THE NET ASSET  VALUE PER UNIT OF  THE PARTNERSHIP DECLINED BY  $1 IN EACH  OF
JANUARY  AND FEBRUARY,  INCREASED BY  $1 IN  MARCH AND  DECLINED AGAIN  BY $2 IN
APRIL, A "PEAK-TO-VALLEY  DRAWDOWN" ANALYSIS CONDUCTED  AS OF THE  END OF  APRIL
WOULD  CONSIDER THAT "DRAWDOWN" TO  BE STILL CONTINUING AND  TO BE $3 IN AMOUNT,
WHEREAS IF THE  NET ASSET  VALUE OF A  UNIT HAD  INCREASED BY $2  IN MARCH,  THE
JANUARY-FEBRUARY  DRAWDOWN WOULD HAVE ENDED AS OF  THE END OF FEBRUARY AT THE $2
LEVEL. SUCH "DRAWDOWNS" ARE MEASURED ON THE BASIS OF MONTH-END NET ASSET  VALUES
ONLY, AND DO NOT REFLECT INTRA-MONTH FIGURES.
 
    "MONTHLY  RATE OF RETURN"  IS NET PERFORMANCE FOR  THE MONTH (GROSS REALIZED
PROFIT (LOSS),  PLUS  INCREASE  (DECREASE) IN  UNREALIZED  PROFIT  (LOSS),  PLUS
INTEREST  INCOME, MINUS BROKERAGE COMMISSIONS, MANAGEMENT AND INCENTIVE FEES AND
OTHER EXPENSES) DIVIDED BY THE BEGINNING NET ASSET VALUE FOR THE MONTH.
 
    "COMPOUND ANNUAL (PERIOD) RATE OF RETURN" IS CALCULATED BY MULTIPLYING ON  A
COMPOUND  BASIS  EACH  OF THE  MONTHLY  RATES OF  RETURN  AND NOT  BY  ADDING OR
AVERAGING SUCH MONTHLY RATES OF RETURN. FOR  PERIODS OF LESS THAN ONE YEAR,  THE
RESULTS ARE YEAR-TO-DATE.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                           OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS
 
    LIQUIDITY.  The assets of the Partnership are deposited with DWR in  futures
interests  trading accounts established by DWR  for the Trading Advisors and are
used by the Partnership as margin to engage in trading. DWR holds such assets in
either designated  depositories  or  in  securities approved  by  the  CFTC  for
investment  of  customer funds.  See "Investment  Program,  Use of  Proceeds and
Trading Policies." The Partnership's  assets held by DWR  may be used as  margin
solely for the Partnership's trading. Since the Partnership's sole purpose is to
trade in futures interests, it is expected that the Partnership will continue to
own such liquid assets for margin purposes.
 
    The Partnership's investment in futures interests may, from time to time, be
illiquid. See "Risk Factors--Risks Relating to Futures Interests Trading and the
Futures  Interests  Markets--Futures Interests  Trading  May be  Illiquid." Most
United States futures exchanges limit  fluctuations in certain futures  interest
prices  during  a  single  day  by  regulations  referred  to  as  "daily  price
fluctuations limits" or "daily limits."  Pursuant to such regulations, during  a
single  trading day no trades may be  executed at prices beyond the daily limit.
If the price for a particular futures interest has increased or decreased by  an
amount  equal  to the  "daily  limit," positions  in  such futures  interest can
neither be taken nor liquidated unless  traders are willing to effect trades  at
or  within the limit. Futures interests prices have occasionally moved the daily
limit for  several consecutive  days  with little  or  no trading.  Such  market
conditions  could prevent the Partnership  from promptly liquidating its futures
interests  and  result  in  restrictions  on  redemptions.  However,  since  the
commencement  of trading by  the Partnership, there  has never been  a time when
illiquidity has affected  a material  portion of the  Partnership's assets.  See
"Redemptions."
 
    CAPITAL  RESOURCES.  The  Partnership does not  have, nor does  it expect to
have, any  capital assets.  Redemptions and  sales of  additional Units  in  the
future  will affect  the amount  of funds  available for  investments in futures
interests in subsequent periods. As redemptions are at the discretion of Limited
Partners, it is not possible to estimate the amount and therefore the impact  of
future redemptions.
 
    RESULTS OF OPERATIONS.  Due to the nature of the Partnership's business, the
Partnership's  results depend on  the Trading Advisors and  the ability of their
trading  systems  to  take  advantage   of  price  movements  or  other   profit
opportunities in the futures interests markets. The following presents a summary
of  the Partnership's operations for  the years 1993, 1994  and 1995 and for the
six months ended June  30, 1996, and a  general discussion of the  Partnership's
trading  activities in  certain markets during  each period. It  is important to
note, however, that the Trading Advisors  trade in various markets at  different
times  and that prior  activity in a  particular market does  not mean that such
market will be actively traded by a Trading Advisor or will be profitable in the
future. Consequently, the results of operations of the Partnership are difficult
to discuss  other  than  in  the  context  of  each  Trading  Advisor's  trading
activities  on behalf of the Partnership as  a whole and how the Partnership has
performed in the past. See "Performance Record of the Partnership" and "Selected
Financial Data" above and the Partnership's financial statements herein.
 
    RESULTS OF OPERATIONS FOR  THE FISCAL YEAR 1993.   In 1993, the  Partnership
recorded profits of 41.6% to close out the year at a Net Asset Value per Unit of
$1,589.53.
 
    The  Partnership posted  strong profits  in each  of the  year's first three
quarters. Profits  in  the first  quarter  resulted from  significant  gains  in
February  from trading in currencies, as  the Japanese yen trended higher versus
the U.S. dollar and major European  currencies, and in financial futures as  the
Fund  benefited from a rally in global  bond prices. The second quarter provided
the Partnership additional profits as gains  of more than 10% in April  resulted
from  continued strengthening of the yen as well  as from a sharp move higher in
precious metals and a strong move in global stock index futures.
 
    The third quarter for the Partnership  began strong in July with profits  of
almost  14%  from  trading  in  energies,  metals  and  European  bond  futures.
Unfortunately, a portion of these gains were offset by
 
                                       28
<PAGE>
losses in August and  September as a  result of a sharp  reversal in the  upward
trend  in domestic commodities as energies and precious metals failed to sustain
their July trends. The Partnership's trading  in the fourth quarter resulted  in
small  gains as profits  in December from trading  in energies and agriculturals
offset smaller losses in currencies and metals during October and November.
 
    Overall, 1993 was a successful year for the Partnership as the Partnership's
aggressive trading  strategies resulted  in significant  profits in  the  year's
first  seven months  when trends in  domestic and  international futures markets
were evident. The Partnership also limited losses later in the year by remaining
diversified over a wide variety of distinct market sectors.
 
    RESULTS  OF  OPERATIONS  FOR  THE  FISCAL  YEAR  1994.    During  1994,  the
Partnership  recorded a net  loss of 5.1% to  close out the year  at a Net Asset
Value per Unit of $1,508.07.
 
    In January, extreme short-term volatile  price movement across a variety  of
market sectors netted losses for the Partnership in global interest rate futures
(Japanese  Government bond, French bond and German  bond futures), as well as in
major currency  values  versus the  U.S.  dollar. Difficult  trading  conditions
continued into February causing losses in the currency, energy and international
stock  index futures markets. Performance rebounded for the Partnership in March
with gains of about 12.5%, as significant profits were recorded in the financial
and currency sectors.
 
    Small losses  were recorded  in April  for the  Partnership primarily  as  a
result  of a  sharp increase  in value of  the U.S.  dollar on  April 5th, after
decreasing late in March.
 
    In May,  the Partnership's  long positions  in coffee  provided gains  as  a
severe  winter  rallied prices  in Brazil.  Energy and  base metals  prices also
increased and  gains in  short-term U.S.  and long-term  European interest  rate
futures  were profitable.  Gains by the  Partnership were also  generated in the
currency markets during  June as a  result of the  U.S. dollar's decline  versus
major European currencies.
 
    The  Partnership's losses in July were the result of reversals in previously
established downward trends in the U.S. and global interest rate futures markets
and a sudden  strengthening of  the U.S.  dollar versus  most major  currencies.
Negative  performance for the  Partnership in August was  due to trendless price
patterns across  a  majority  of  domestic  futures  markets  including  energy,
currencies,  metals and financial markets.  September's gains by the Partnership
in the energy and  currency market offset  a portion of  overall losses for  the
quarter.
 
    The  Partnership's losses in October  resulted from trendless price movement
in global financial futures  and from short-term  volatility in precious  metals
and energy prices. Gains by the Partnership in November resulted from trading in
eurodollar and U.S. Treasury note futures. Additional gains resulted from upward
trends  in sugar, cotton and base metals prices. A sudden move downward in value
of the U.S. dollar on December 28th caused losses for the Partnership from  long
U.S. dollar positions versus the Japanese yen, Swiss franc and British pound.
 
    Overall, 1994 proved to be a modestly difficult year for the Partnership due
primarily  to the  lack of  sustained price  trends in  the currency  and global
financial futures complexes.  Smaller profits from  trading in soft  commodities
and base metals during the year offset a majority of the Partnership's losses.
 
    RESULTS  OF  OPERATIONS  FOR  THE  FISCAL  YEAR  1995.    During  1995,  the
Partnership recorded profits of 23.6%  to finish the year  at a Net Asset  Value
per Unit of $1,864.21.
 
    In  January, trading  losses were recorded  by the Partnership  early in the
month as a result of a decline in the value of the U.S. dollar relative to  most
major  world currencies. Smaller losses by the Partnership were recorded in both
U.S. and international interest rate futures trading due to short-term  volatile
price  movement. In February  and March, significant gains  were recorded by the
Partnership from trading in both financial futures and currencies. In  financial
futures,  increased  interest rate  futures  prices over  this  two-month period
resulted in gains from  long positions in global  bond futures. In the  currency
markets,  a decline in the value of  the U.S. dollar resulted in trading profits
for the Partnership's long positions in the Japanese yen, German mark and  Swiss
and French francs.
 
                                       29
<PAGE>
    The  Partnership's positive performance continued into  April and May as the
previously established long  positions in both  U.S. and international  interest
rate  futures profited from the upward trend in interest rate futures prices. In
addition, the value of the Japanese yen relative to the U.S. dollar continued to
move higher early in April contributing to the overall Partnership gains  during
the month. Smaller gains were recorded from long S&P 500 Index futures positions
as domestic stock prices moved higher during May.
 
    Trading  losses were recorded  by the Partnership during  June as the upward
price trend in  overseas bond  futures subsided. Small  Partnership losses  were
recorded  during June in  agricultural futures from trading  in soybean and corn
futures, and in currencies as foreign currencies moved in a narrow trading range
versus the U.S. dollar and one another.
 
    In July, the Partnership experienced a difficult trading environment in U.S.
and global interest rate futures, as  prices retreated from their previous  move
higher.  Trendless price  movement also  resulted in  losses within  the metals,
agricultural and energy market sectors. Losses were recorded by the  Partnership
during  August as global  interest rate futures  prices moved without consistent
direction. Additional  losses  were recorded  by  the Partnership  in  the  soft
commodities markets due to short-term volatile price movement. During September,
losses  were recorded by the Partnership due to a dramatic trend reversal in the
upward move of the U.S. dollar relative to most European currencies on September
20 and 21. Smaller losses were recorded during this period in energy futures  as
prices declined abruptly, resulting in losses from long oil and gas positions.
 
    Trading  in international  interest rate  futures by  the Partnership during
October resulted  in net  losses as  global bond  prices moved  in a  short-term
volatile  pattern. Trendless  price movement in  stock index,  energy and metals
futures prices  resulted  in  additional losses  being  recorded.  In  November,
financial futures trading by the Partnership was profitable as increasing global
bond  futures prices  resulted in  gains being  recorded from  long positions in
European, U.S.,  Japanese and  Australian  government bond  futures.  Additional
trading  gains were recorded from trading in soft commodities. Long positions in
natural gas  futures  resulted  in  significant gains  during  December  by  the
Partnership  as prices  increased dramatically.  Additional gains  were recorded
from long positions  in both crude  and heating oil  futures. Long positions  in
European  and  U.S. bond  futures also  contributed  profits during  December as
European and U.S. bond futures prices continued their bullish trend.
 
    Overall, the Partnership recorded strong gains for the year primarily due to
participation in global interest  rate futures, as  both U.S. and  international
interest  rate futures  witnessed sustained  upward price  trends during several
periods of the year. These gains, coupled with gains in the currency markets  in
the year's first half, constituted a majority of the profits for the year.
 
    In  summary of the three years, the General Partner believes that there were
fewer sustained trends  in 1994 than  in 1993 and  1995 as a  result of  several
factors, including a change in monetary policy by the U.S. Federal Reserve which
affected  global  interest rate  futures; a  relatively  flat U.S.  stock market
resulting in little price  movement in U.S. stock  index futures; fewer  weather
interruptions  resulting in steadier prices  for certain commodities; relatively
unchanged  gold  prices  affecting  other  precious  metals;  and  the  lack  of
significant  changes in value for many  of the world's major currencies relative
to the U.S. dollar and one another.
 
    RESULTS OF OPERATIONS FOR THE SIX MONTHS  ENDED JUNE 30, 1996.  Through  the
first  six months of 1996, the Partnership recorded a net loss of 11.2%; the Net
Asset Value per Unit at June 30, 1996 was $1,655.66. The most significant losses
were experienced in global interest rate futures trading during February, as the
previous upward price trend  that was profitable in  late 1995 and January  1996
reversed  sharply  lower.  As a  result,  losses were  recorded  from previously
established long positions in U.S.  and European interest rate futures.  Smaller
losses  were  recorded  in non-U.S.  bond  futures  from March  through  June as
trendless price movement  followed. Losses  were also recorded  in global  stock
index  futures, as choppy  price movement was experienced  during March, May and
June. In other markets, losses were  recorded from soft commodities trading,  as
sugar  and coffee prices moved  in a trendless pattern  throughout a majority of
the  period.   Smaller   losses   were   recorded   from   metals   and   energy
 
                                       30
<PAGE>
futures  trading, as  short-term price volatility  was experienced  early in the
first quarter.  These losses  were partially  offset by  gains recorded  in  the
currency  markets from short Japanese yen positions during January and March, as
the value of  the yen  declined versus the  U.S. dollar.  Additional gains  were
recorded from short German mark and Swiss franc positions, as the value of these
currencies moved lower relative to other world currencies during April, and from
long Australian dollar positions, as its value moved higher during March.
 
    To  enhance the foregoing  comparison of results of  operations from year to
year, prospective  investors  can  examine,  line  by  line,  the  Partnership's
Statements  of Operations and  Statements of Financial  Condition. Total trading
results decreased during the first  half of 1996 relative  to the first half  of
1995.  Total trading results were profitable in  1993 and in 1995 versus smaller
gains in 1994  and losses  in 1992.  Strong results in  1993 and  1995 were  the
result  of  significant  price  trends  across  a  variety  of  futures markets,
particularly currencies  and global  financial futures.  Such periods  of  price
trends  provide  good  profit  opportunities  for  the  trend-following  trading
strategies of the Partnership's three  Trading Advisors. Futures price  activity
in  1992 and  1994 was characterized  by more trendless  and short-term volatile
price movement across  a majority  of markets,  thus creating  a more  difficult
trading environment for the Partnership's Trading Advisors.
 
    INTEREST INCOME AND EXPENSES.  Interest income to the Partnership is derived
from  80% of  its assets earning  interest at  the prevailing rate  paid on U.S.
Treasury bills. The  size of the  assets and the  fluctuation of interest  rates
affect  the resulting  interest income  annual totals.  Interest income  for the
Partnership has increased each  fiscal year since 1992.  Despite a reduction  in
U.S.  Treasury bill rates in 1993, interest income in 1993 was greater than 1992
because the Partnership's assets grew as a result of strong trading profits  and
additional  subscriptions in October 1993. Increasing interest rates in 1994 and
a larger  asset  size  throughout  the year  resulted  in  significantly  higher
interest  income to the Partnership. In 1995, the increase in asset size was the
primary reason for an increase in  interest income to the Partnership.  Interest
income  to the Partnership decreased during the first half of 1996 when compared
to the first  half of  1995 as a  result of  a reduction in  U.S. Treasury  bill
rates, as well as a decrease in the Partnership's assets.
 
    In  regard  to  expenses  to  the  Partnership,  brokerage  commissions  and
transaction fees and costs charged fluctuate  based on the volume of trading  by
the   Partnership's  Trading  Advisors.  In   1993,  brokerage  commissions  and
transaction fees and costs  increased as a result  of increasing trading  volume
due  primarily to the  increase in size  of the Partnership.  In 1994, a further
increase  in  brokerage  commissions  and  transaction  fees  and  costs  and  a
corresponding  increase in trading volume was due  to larger asset size over the
full year, coupled with an increased level of trading resulting from more short-
term volatile  price  movement  in  a majority  of  futures  markets.  Brokerage
commissions  and transaction fees and costs declined  in 1995 as a result of the
presence of more  long-term price  trends in a  majority of  futures markets  in
which the Partnership's Trading Advisors concentrate their participation. During
the  first half  of 1996, brokerage  commissions and transaction  fees and costs
charged to the Partnership decreased relative to the first half of 1995 due to a
reduction in the Partnership's Net Assets.
 
    Management fees to the  Partnership are charged at  a 3% annualized rate  of
Net  Assets and fluctuate based only on  the size of Net Assets. Management fees
have increased each year since  1992 in direct proportion  to the assets of  the
Partnership. Management fees decreased during the first half of 1996 relative to
the  first half  of 1995  as a  result of  the reduction  in assets  during this
period. Incentive fees are paid on a quarterly basis or on any redeemed Units on
a monthly basis if the Partnership is profitable. Incentive fees have  increased
each year as a result of positive quarterly performance and Units being redeemed
at  a profit. Incentive fees charged to the Partnership during the first half of
1996 decreased relative to the first half  of 1995 as a result of an  adjustment
of previous accruals.
 
    Common  administrative expenses  to the  Partnership are  costs and expenses
used to pay legal, accounting, auditing, printing and distribution costs and are
capped at 0.25% per annum. These
 
                                       31
<PAGE>
expenses on a  gross basis  have shown relatively  little fluctuation  and as  a
percentage  of assets have decreased  over time. During the  first half of 1996,
administrative expenses charged to the  Partnership were reduced as compared  to
the first half of 1995.

Financial Statements of Dean Witter Select Futures Fund L.P." herein.
 
    OFF-BALANCE SHEET RISK.  The Partnership is a party to financial instruments
with elements  of off-balance  sheet  market and  credit risk.  The  Partnership
trades futures, options, and forward contracts in interest rates, stock indices,
commodities,  currencies, petroleum and precious  metals. In entering into these
contracts there  exists  a risk  to  the  Partnership (market  risk)  that  such
contracts may be significantly influenced by market conditions, such as interest
rate volatility, resulting in such contracts being less valuable. If the markets
should  move  against  all  of  the  futures  interests  positions  held  by the
Partnership at the same time, and if the Trading Advisors were unable to  offset
futures  interests positions of the Partnership,  the Partnership could lose all
of its assets and the Limited Partners would realize a 100% loss. In addition to
the internal controls of each Trading  Advisor, the Trading Advisors must be  in
compliance  with the Trading Policies of  the Partnership. Such Trading Policies
include standards for  liquidity and  leverage with which  the Partnership  must
comply.  Each Trading Advisor and the  General Partner monitor the Partnership's
trading  activities  to  ensure  compliance  with  the  Trading  Policies.   See
"Investment  Program, Use  of Proceeds and  Trading Policies--Trading Policies."
The General Partner may (under the terms of the Management Agreements) require a
Trading Advisor to modify  positions of the Partnership  if the General  Partner
believes they violate the Partnership's Trading Policies.
 
    In  addition to market  risk, in entering into  futures, options and forward
contracts there is a credit risk to  the Partnership that the counterparty on  a
contract  will  not be  able to  meet  its obligations  to the  Partnership. The
ultimate counterparty of  the Partnership  for futures contracts  traded in  the
United  States and most foreign exchanges on which the Partnership trades is the
clearinghouse associated  with such  exchange. In  general, a  clearinghouse  is
backed  by  the  membership  of  the  exchange and  will  act  in  the  event of
non-performance by one of its members or  one of its members' customers, and  as
such, should significantly reduce this credit risk. For example, a clearinghouse
may  cover  a  default  by  (i) drawing  upon  a  defaulting  member's mandatory
contributions and/or non-defaulting  members' contributions  to a  clearinghouse
guarantee  fund, established lines  or letters of credit  with banks, and/or the
clearinghouse's surplus capital and other  available assets of the exchange  and
clearinghouse,  or (ii)  assessing its members.  In cases  where the Partnership
trades on a foreign exchange where the clearinghouse is not funded or guaranteed
by the  membership or  where the  exchange is  a "principals'  market" in  which
performance is the responsibility of the exchange member and not the exchange or
a clearinghouse, or when the Partnership enters into off-exchange contracts with
a  counterparty, the sole recourse of the Partnership will be the clearinghouse,
the exchange member or the off-exchange  contract counterparty, as the case  may
be.  For a  list of  the foreign  exchanges on  which the  Partnership currently
trades, see "Investment Program, Use of  Proceeds and Trading Policies" on  page
41.  For an  additional discussion  of the credit  risks relating  to trading on
foreign exchanges, see "Risk Factors -- Risks Relating to Futures Interests  and
the Futures Interest Markets -- Special Risks Associated with Trading on Foreign
Exchanges."
 
    DWR, in its business as an international commodity broker and as a member of
various  futures exchanges, monitors  the creditworthiness of  the exchanges and
clearing members  of the  foreign  exchanges with  which  it does  business  for
clients,  including the Partnership. DWR employees  also from time to time serve
on supervisory or management committees of such exchanges. If DWR believed  that
there  were a  problem with  the creditworthiness  of an  exchange on  which the
Partnership deals,  it would  so advise  the General  Partner. With  respect  to
exchanges  of which DWR is not a  member, DWR acts only through clearing brokers
it has determined  to be creditworthy.  If DWR believed  that a clearing  broker
with  which  it deals  on  behalf of  clients  were not  creditworthy,  it would
terminate its relationship with such broker.
 
                                       32
<PAGE>
    While DWR monitors the creditworthiness and risks involved in dealing on the
various exchanges (and  their clearinghouses) and  with other exchange  members,
there  can be  no assurance  that an  exchange (or  its clearinghouse)  or other
exchange member will be able to meet its obligations to the Partnership. DWR has
not undertaken to indemnify the Partnership  against any loss. Further, the  law
is   unclear,  particularly  with   respect  to  trading   in  various  non-U.S.
jurisdictions, as to whether DWR has  any obligation to protect the  Partnership
from any liability in the event that an exchange or its clearinghouse or another
exchange  member  defaults  on  its  obligations  on  trades  effected  for  the
Partnership.
 
    Although DWR  monitors the  creditworthiness of  the foreign  exchanges  and
clearing  brokers with which it does business for clients, DWR does not have the
capability to precisely quantify the Partnership's exposure to risks inherent in
its trading activities on foreign exchanges, and,  as a result, the risk is  not
monitored  by DWR on an individual  client basis (including the Partnership). In
this regard,  DWR must  clear its  customer  trades through  one or  more  other
clearing brokers on each exchange where DWR is not a clearing member. Such other
clearing  brokers calculate the net margin requirements of DWR in respect of the
aggregate of all of  DWR's customer positions carried  in DWR's omnibus  account
with  that clearing broker.  Similarly, DWR calculates  a net margin requirement
for the exchange-traded futures  positions of each  of its customers,  including
the  Partnership.  Neither DWR  nor DWR's  respective  clearing brokers  on each
foreign futures exchange  calculates the  margin requirements  of an  individual
customer,  such  as  the Partnership,  in  respect of  the  customer's aggregate
contract positions on any particular exchange.
 
    With respect to forward contract  trading, the Partnership trades with  only
those  counterparties  which  the  General  Partner,  together  with  DWR,  have
determined to  be  creditworthy.  As  set forth  in  the  Partnership's  Trading
Policies,  in determining creditworthiness, the  General Partner and DWR consult
with the Corporate Credit  Department of DWR.  Currently, the Partnership  deals
only with DWR as its counterparty on forward contracts.
 
    At June 30, 1996, open futures and forward contracts were:

A portion of the amounts indicated as off-balance sheet risk in forward currency
contracts  is due to offsetting forward commitments  to purchase and to sell the
same currency on the same date in the future. These commitments are economically
offsetting, but are not offset in the forward market until the settlement date.
 
    The unrealized gain on open contracts is reported as a component of  "Equity
in  Commodity futures trading accounts" on  the Statement of Financial Condition
and totaled $4,861,543 at June 30,  1996. Of this amount, $4,733,944 related  to
exchange-traded  futures contracts  and $127,599  related to off-exchange-traded
forward currency contracts.

    Exchange-traded futures contracts held by  the Partnership at June 30,  1996
mature through June 1997. Off-exchange-traded forward currency contracts held by
the Partnership at June 30, 1996 mature through July 1996.
 
    Exchange-traded  futures contracts  are marked  to market  and variations in
value are settled on a daily basis. DWR, as the futures commission merchant  for
all  of  the  Partnership's  exchange-traded  futures  contracts,  is  required,
pursuant to regulations of the  CFTC, to segregate from  its own assets and  for
the  sole benefit of its commodity customers, all funds held by DWR with respect
to exchange-traded  futures contracts,  including  an amount  equal to  the  net
unrealized  gain on  all open futures  contracts, which  totaled $145,997,178 at
June 30, 1996.  With respect  to the  Partnership's off-exchange-traded  forward
currency contracts, there are no daily settlements of variations in value nor is
there  any requirement that an  amount equal to the  net unrealized gain on open
forward contracts  be  segregated.  With respect  to  those  off-exchange-traded
contracts, the Partnership is at risk to the ability of DWR, the counterparty on
all such contracts, to perform.

1.  THE TRADING ADVISORS
 
   
    (a)  MONTHLY MANAGEMENT  FEE.  The Partnership  pays each Trading Advisor  a
monthly  management fee equal  to 1/4 of 1%  (a 3% annual  rate) of such Trading
Advisor's allocated Net Assets (as defined herein on page 86) on the last day of
each month (before deduction for the management fees, any accrued incentive fees
and any redemptions or distributions). For example, if each Trading Advisor were
allocated Net Assets of $20,000,000 as of  the end of each month during a  year,
each  Trading Advisor would receive an  aggregate monthly management fee for the
year of $600,000  (1/4 of 1%  of $20,000,000  per month, or  $50,000 times  12).
During the period August 1991 through August 1996, management fees have averaged
3.06% per year of the Partnership's average month-end Net Assets. For the fiscal
year 1995 management fees equaled $5,626,908.
    
 
    If  during  any month  the Partnership  suspends  trading operations  or the
Partnership does not conduct business operations, or,  as a result of an act  or
material  failure to  act by  a Trading  Advisor, the  Trading Advisor  does not
provide its services on any trading day, then the management fee payable to such
Trading Advisor will be prorated based on  the ratio that the number of  trading
days  in the month which the Partnership  account managed by the Trading Advisor
engaged in trading operations or received  the full utilization of such  trading
systems,  methods, or strategies, as the case  may be, bears to the total number
of trading days in the month.
 
                                       36
<PAGE>
    If the Management Agreement is terminated on a date other than the first day
of a calendar month, the management fee described above will be determined as if
such date were the first day of a month, but such fee will be prorated based  on
the  ratio by which the number of trading  days in the month through the date of
termination bears to the total number of trading days in the month.
 
   
    (b)  QUARTERLY INCENTIVE  FEE.  The Partnership  pays a quarterly  incentive
fee  equal to 17  1/2% of the  Trading Profits experienced  with respect to each
Trading Advisor's allocated Net Assets (as defined herein on page 86) as of  the
end  of each calendar quarter. "Trading Profits"  is defined to mean net futures
interests trading  profits  (realized  and unrealized)  earned  on  the  Trading
Advisor's  allocated Net Assets, decreased by monthly management fees, brokerage
commissions, floor brokerage fees, "give up"  or transfer fees, NFA fees,  other
transaction  fees and costs,  a prorata portion  of administrative expenses, and
other fees and expenses which are chargeable to the Trading Advisor's  allocated
Net  Assets; with such Trading Profits and items of decrease determined from the
end of the last  calendar quarter in  which an incentive fee  was earned by  the
Trading  Advisor  or, if  no incentive  fee  has been  previously earned  by the
Trading Advisor, from the date the  Partnership commenced trading to the end  of
the  calendar  quarter  as of  which  such  incentive fee  calculation  is made.
Extraordinary expenses  of the  Partnership, if  any, will  not be  deducted  in
determining  Trading  Profits. No  incentive fee  will be  paid with  respect to
interest income of the Partnership. Any  accrued incentive fees with respect  to
any  Units redeemed at  the end of  a month which  is not the  end of a calendar
quarter will  be  deducted and  paid  to the  Trading  Advisor at  the  time  of
redemption.  During the period  August 1991 through  August 1996, incentive fees
have averaged 3.60% per year of the Partnership's average month-end Net  Assets.
For  the  fiscal year  1995  incentive fees  equaled  $8,707,049. So  as  not to
disadvantage existing Limited Partners, if  a Trading Advisor has experienced  a
loss at the time of a closing, a Trading Advisor must earn back such loss plus a
pro  rata amount relating to the new funds allocated to the Trading Advisor at a
subsequent closing before the Trading Advisor will be eligible for an  incentive
fee.
    
 
    If  any payment of incentive fees is made to a Trading Advisor on account of
Trading Profits earned with respect to its allocated Net Assets and the  Trading
Advisor  thereafter fails to earn Trading  Profits or experiences losses for any
subsequent calendar quarter, the Trading Advisor will be entitled to retain such
amounts of incentive fees previously paid  to the Trading Advisor in respect  of
such  Trading Profits. However, no incentive fees will be payable to the Trading
Advisor for subsequent calendar quarters until Trading Profits have been  earned
with  respect to its allocated Net Assets;  PROVIDED, HOWEVER, that if a Trading
Advisor's allocated Net Assets are reduced or increased because of  redemptions,
reallocations  or subscriptions which occur  at the end of,  or subsequent to, a
calendar quarter in which  the Trading Advisor  experiences a futures  interests
trading loss with respect to its allocated Net Assets, the trading loss for that
calendar  quarter which must be recovered before the Net Assets allocated to the
Trading Advisor will  be deemed to  experience Trading Profits  will be  reduced
proportionately based upon such redemptions, reallocations, or subscriptions.
 
    Thus, for example, if a Trading Advisor earned Trading Profits of $1,000,000
with  respect to its  allocated Net Assets  for the quarter  ended March 31, the
Trading Advisor would receive an incentive fee of $175,000 for that period.  If,
however,  the  Trading Advisor  experiences  realized and/or  unrealized trading
losses, or fees and expenses which offset trading profits, so as to result in  a
$250,000  loss with respect  to its allocated  Net Assets for  the quarter ended
June 30, no incentive fee will be  paid to the Trading Advisor for that  period.
If  the  Trading Advisor  is  to earn  an incentive  fee  for the  quarter ended
September 30, the Trading Advisor will  have to earn profits exceeding  $250,000
on behalf of the Partnership for that period, since the incentive fee is payable
measured  from the last calendar  quarter as of which  an incentive fee was paid
(I.E., March 31), and  not the immediately preceding  calendar quarter. For  the
calendar  quarter  ended September  30, Trading  Profits would  be equal  to the
amount of profits in  excess of $250,000. The  Trading Advisor would receive  an
incentive  fee for such quarter  equal to 17 1/2%  of such Trading Profits. (The
foregoing examples assume no redemptions, reallocations or additional  purchases
of  Units during  the periods  in question,  which would  require adjustments as
described above.)
 
                                       37
<PAGE>
    Because incentive fees are determined  and paid separately for each  Trading
Advisor,  the Partnership may be required to pay  an incentive fee to one or two
Trading Advisors in any given  quarter in spite of losses  or a lack of  Trading
Profits experienced by the Partnership as a whole.
 
    If  a Management Agreement is terminated as of any date which is not the end
of a calendar quarter, the incentive fee described above, if applicable, will be
determined as if such termination  date were at the  end of a calendar  quarter.
See "The Management Agreements."
 
2.  DEAN WITTER REYNOLDS INC.
 
   
    (a)   BROKERAGE COMMISSIONS.  The Partnership pays DWR brokerage commissions
at a roundturn rate (covering both the taking and liquidation of a position)  of
80% of DWR's published non-member rates for speculative accounts (which, for the
futures  interests to be  traded by the  Partnership, is equal  to an average of
$75). Effective  as  of  September  1,  1996,  commissions,  together  with  the
transaction fees and costs described below, were capped at 13/20 of 1% per month
(a  maximum  7.8% annual  rate)  of the  Partnership's  Net Assets  at month-end
allocated  to   each  Trading   Advisor  (determined   before  redemptions   and
distributions  as of the end  of such month). In  addition, the aggregate of (i)
brokerage commissions and transaction fees and costs payable by the Partnership,
and (ii) the net excess interest and compensating balance benefits to DWR (after
crediting the  Partnership with  interest)  cannot exceed  14% annually  of  the
Partnership's average month-end Net Assets during each calendar year. During the
period  August  1991 through  August 1996,  brokerage commissions  have averaged
8.12% per year of the Partnership's average month-end Net Assets. For the fiscal
year 1995 brokerage  commissions equaled $14,173,695.  The Partnership pays  DWR
brokerage  commissions  for  currency  forward  contract  transactions  at rates
established with reference to the brokerage commission rate charged on exchange-
traded currency futures contracts. DWR may  from time to time adjust the  United
States  dollar  size  of  currency  forward  contracts  so  that  the  brokerage
commission rate charged on such contracts  will approximate the rate charged  on
exchange-traded  currency  futures  contracts of  similar  United  States dollar
value. In  the  case of  currency  futures  contracts traded  on  United  States
exchanges,  the Partnership pays DWR brokerage commissions at the rate described
above.
    
 
    Although the rate being charged to the Partnership is 80% of DWR's published
non-member rates for speculative accounts, most  customers of DWR who have  over
$1,000,000  in futures interests accounts with DWR pay commissions at negotiated
rates which  are substantially  less  than the  rate  paid by  the  Partnership,
notwithstanding  the  caps  described  above. Other  customers  of  DWR  may pay
brokerage commissions at rates which are substantially lower or which are higher
than the rates that  the Partnership pays, and  other commodity brokerage  firms
may  offer  lower  rates to  accounts  the  size of  the  Partnership's account.
However, the General Partner believes that the brokerage commissions charged  to
the  Partnership are less than the  brokerage rates charged certain other public
commodity pools.
 
    DWR paid all of the costs (aggregating $665,132) incurred in connection with
the organization  of  the  Partnership  and  the  Initial  Offering  and  Second
Offering,  and  will pay  all  of the  costs  incurred in  connection  with this
offering, estimated to be  approximately $875,000 in  the aggregate. Such  costs
include legal, accounting and auditing fees, printing costs, filing fees, escrow
fees,  marketing costs (which  include costs relating to  sales seminars and the
preparation of customer sales  kits and brochures), and  other related fees  and
expenses.  The  Partnership has  not and  will  not reimburse  DWR for  any such
organizational and Initial Offering and Second Offering costs, and while DWR may
recoup the  costs  of this  offering  from  brokerage commissions  paid  by  the
Partnership, the Partnership will not be liable for any such costs at any time.
 
    (b)  FINANCIAL BENEFITS.  DWR benefits from the interest credit arrangements
and  possible compensating balance treatment  in connection with its designation
of a  bank  or  banks in  which  the  Partnership's assets  are  deposited.  See
"Investment Program, Use of Proceeds and Trading Policies."

3.  OTHER
 
   
    (a)   ADMINISTRATIVE AND  EXTRAORDINARY EXPENSES.   The Partnership pays its
ordinary administrative  expenses.  Such  expenses  include  legal,  accounting,
auditing,   recordkeeping,  administration,  computer,   and  clerical  expenses
(including expenses incurred in preparing reports and tax information to Limited
Partners and regulatory authorities and expenses for specialized  administrative
services),  printing and duplication expenses, mailing expenses and filing fees.
Ordinary  administrative  expenses   have  averaged  0.15%   per  year  of   the
Partnership's average month-end Net Assets from August 1991 through August 1996.
For  the fiscal year 1995 ordinary administrative expenses equaled $148,000. The
General Partner or an affiliate thereof will pay and will not be reimbursed  for
any   such  administrative  expenses  in  excess   of  0.25%  per  year  of  the
Partnership's average  Net  Assets  (calculated  on the  basis  of  the  average
month-end  Net Assets during each calendar  year). The General Partner shall not
be reimbursed by the Partnership for any costs incurred by it relating to office
space,  equipment,   and  staff   necessary  for   Partnership  operations   and
administration  of redemptions of Units. The Partnership is obligated to pay any
extraordinary expenses it may incur.  Extraordinary expenses will be  determined
in  accordance with  generally accepted  accounting principles,  which generally
include events that are both unusual  in nature and occur infrequently. For  the
period August 1991 through June 1996, no extraordinary expenses were paid by the
Partnership.
    
 
   
    (b)   TRANSACTION FEES AND  COSTS.  The Partnership  pays separately for all
floor brokerage fees, exchange fees, clearinghouse fees, NFA fees, "give up"  or
transfer  fees, any costs associated with  taking delivery of futures interests,
fees for the execution of forward  contract transactions, the execution of  cash
transactions relating to exchange of futures for physicals ("EFP") transactions,
and   the  use  of  DWR's   institutional  and  overnight  execution  facilities
(collectively, "transaction fees and costs"). The Partnership pays DWR a fee for
each forward contract, which averages between $3 and $6 per roundturn  contract,
depending  upon the size  of the trades.  DWR does not  charge the Partnership a
mark-up or spread (a charge  over the price at  which DWR obtained the  position
for  its own account) on such forward  trading. DWR charges a transaction fee of
approximately $2.50  for  each cash  contract  transaction relating  to  an  EFP
transaction,  and a transaction  fee for the use  of the institutional execution
desk or overnight  execution facilities  which may be  up to  $3 per  roundturn.
During  the period August  1991 through August 1996,  transaction fees and costs
averaged 0.80% per year of the Partnership's average month-end Net Assets.  Such
percentage  could be  significantly higher  and may  be lower,  depending on the
Partnership's trading activity and the types  of trades executed by the  Trading
Advisors.   For  the  fiscal  year  1995  transaction  fees  and  costs  equaled
$1,589,795. Effective as of  September 1, 1996,  the aggregate transaction  fees
and  costs and brokerage commissions incurred by the Partnership with respect to
each Trading Advisor's allocated Net Assets were capped at 13/20 of 1% per month
of the Partnership's month-end Net Assets allocated to such Trading Advisor.  In
addition,  these fees and costs  are subject to the  14% annual cap on aggregate
brokerage commissions, transaction fees and  costs, and net excess interest  and
compensating balance benefits to DWR, described under "--2. Dean Witter Reynolds
Inc.--(a) Brokerage Commissions" above.
    
 
    As long as redemption charges are imposed, as described under "Redemptions,"
the management fee, incentive fee and caps on brokerage commissions, transaction
fees  and costs, ordinary  administrative expenses, and  net excess interest and
compensating balance benefits  may not  be increased. Thereafter,  none of  such
fees  and caps may be  increased unless Limited Partners  are given prior notice
thereof (including  a description  of redemption  and voting  rights of  Limited
Partners)  and  an  opportunity  to  redeem  their  Units.  Notwithstanding  the
foregoing, in accordance  with guidelines  applied by  certain state  securities
regulators  (see  "Glossary--Blue  Sky Glossary"),  the  Partnership's  fees and
expenses are  subject to  the following  limits: (a)  the aggregate  of (i)  the
management fees payable by the Partnership, and (ii) the Partnership's customary
and routine administrative expenses (other than commodity brokerage commissions,
transaction  fees  and  costs,  incentive  fees,  legal  and  auditing  fees and
expenses, and  extraordinary  expenses), shall  not  exceed  1/2 of  1%  of  the
Partnership's  Net  Assets per  month,  or 6%  of  the Partnership's  Net Assets
annually; (b) the  quarterly incentive  fee payable  by the  Partnership to  any
Trading  Advisor for the  Partnership shall not exceed  15% of the Partnership's
 
                                       39
<PAGE>
Trading Profits (as  defined herein), PROVIDED  that such incentive  fee may  be
increased  by 2% for each 1% by  which the aggregate fees and expenses described
in clause (a) of  this sentence are  limited below the 6%  of Net Assets  annual
limit  thereon (I.E., if such fees and expenses are limited to 4% of Net Assets,
the maximum incentive fee  payable may be increased  to 19%); (c) the  brokerage
commissions (excluding transaction fees and costs) payable by the Partnership to
DWR  or any other commodity  broker for the Partnership  shall not exceed 80% of
DWR's  or  such  other  commodity   broker's  published  non-member  rates   for
speculative  accounts; and  (d) the aggregate  of (i)  the brokerage commissions
payable by  the  Partnership  to DWR  or  any  other commodity  broker  for  the
Partnership, (ii) the transaction fees and costs payable by the Partnership, and
(iii)  the net excess interest  and compensating balance benefits  to DWR or any
other commodity broker for the Partnership (after crediting the Partnership with
interest,  as  described  herein),  shall   not  exceed  14%  annually  of   the
Partnership's average monthly Net Assets as of the last day of each month during
each  calendar year. The  General Partner or  an affiliate thereof  will pay any
fees and expenses in excess of any such limits.
 
   
    The foregoing commissions, fees, costs and expenses may equal a  significant
percentage  of the annual  average Net Assets  of the Partnership.  Based on the
foregoing fees and expenses of the Partnership, the Partnership will be required
to earn estimated annual  trading profits (after  taking into account  estimated
interest  income  based upon  current  rates of  5%) of  7.06%  per year  of the
Partnership's  average  annual  Net  Assets  in  order  to  avoid  depletion  or
exhaustion  of the  assets of  the Partnership.  This assumes  that each Trading
Advisor's gross profits equal expenses such that no incentive fees are earned by
the Trading Advisor, and  results from the fact  that in calculating  management
fees, accrued management fees are not deducted from Net Assets.
    
 
4.  BREAK EVEN ANALYSIS
 
   
    Based  upon the annual fees and expenses of the Partnership, the Partnership
will be required to  earn trading profits (after  taking into account  estimated
interest  income) of 10.16% per year of  its annual average annual Net Assets in
order for a  Limited Partner  to pay  the redemption  charge and  to recoup  its
initial investment upon redemption after one year.
    
 
   
    Based  upon the selling  price as of  August 31, 1996,  the Partnership must
earn net trading profits of $164.97 per Unit, in order for a Limited Partner  to
recoup  its initial investment  upon redemption of  a Unit after  one year after
payment by the  Partnership of  its expenses and  payment of  the 3%  redemption
charge (as calculated below).

NOTES
 
   
(1) Units  of each Partnership  are offered for  sale at the  First, Second, and
    Third Closings at a purchase price equal  to 100% of the Net Asset Value  of
    the  Unit  as  of  the close  of  business  on  the last  day  of  the month
    immediately preceding the applicable closing.
    
 
(2) Monthly management fees are equal to 1/4  of 1% of the Net Assets  allocated
    to each Trading Advisor on the last day of each month (a 3% annual rate).
 
                                       40
<PAGE>
   
(3) Brokerage  commissions  have averaged  8.12% per  year of  the Partnership's
    average  month-end  Net  Assets   since  inception  of  trading.   Brokerage
    commissions  are  charged at  a  roundturn rate  of  80% of  DWR's published
    non-member rates for speculative accounts (which for futures interests to be
    traded by the Partnership is  equal to an average  of $75). Effective as  of
    September 1, 1996, aggregate commissions and transaction fees and costs were
    capped  at  13/20  of 1%  per  month (a  maximum  7.8% annual  rate)  of the
    Partnership's Net Assets at month-end allocated to each Trading Advisor. For
    purposes of the above table, brokerage commissions were assumed to be  6.92%
    based on adjusting prior brokerage commissions for the new cap.
    
 
(4) Administrative  expenses have averaged  0.15% per year  of the Partnership's
    average month-end  Net Assets  since  inception of  trading.  Administrative
    expenses  in excess of 0.25% per year of the Partnership's average month-end
    Net Assets will be paid by the  General Partner or an affiliate thereof  and
    will  not be reimbursed by the Partnership. For purposes of the above table,
    administrative expenses were assumed to be 0.25%.
 
   
(5) Transaction fees and costs have averaged 0.80% per year of the Partnership's
    average month-end Net  Assets since  inception of trading.  Effective as  of
    September  1,  1996,  aggregate  transaction fees  and  costs  and brokerage
    commissions were  capped at  13/20  of 1%  per  month of  the  Partnership's
    month-end  Net Assets allocated to each Trading Advisor. For purposes of the
    above table, transaction fees and costs were assumed to be 0.80%.
    
 
(6) Effective on the day of the  First Closing, DWR will credit the  Partnership
    at  month-end with  interest income as  if 80% of  the Partnership's average
    daily Net Assets for the  month were invested at  a prevailing rate on  U.S.
    Treasury Bills. Such rate was estimated at 5% for the period.
 
(7) Units  redeemed at the end of one year from the date of purchase are subject
    to a 3% redemption charge.
 
(8) Incentive fees are assumed to be zero because (i) interest income is greater
    than the  redemption fee  and (ii)  each Trading  Advisor's trading  profits
    equal expenses.
 
    The General Partner will furnish to each Limited Partner a monthly statement
describing  the performance  of the Partnership  and setting  forth, among other
things,  aggregate  management  and   incentive  fees,  brokerage   commissions,
transaction fees and costs, administrative expenses, and other fees and expenses
incurred  or  accrued by  the  Partnership during  the  month and  certain other
information.  See  "The  Limited   Partnership  Agreement--Reports  to   Limited
Partners."
 
            INVESTMENT PROGRAM, USE OF PROCEEDS AND TRADING POLICIES
 
    The  Partnership is a Delaware limited  partnership, formed in March 1991 to
engage primarily in  the speculative  trading of futures  interests. The  entire
proceeds  of this offering of Units and  the capital contribution of the General
Partner will be deposited in the Partnership's accounts maintained with DWR, and
all of such proceeds will be allocated  for use by the Partnership to engage  in
futures  interests  trading pursuant  to  instructions provided  by  the Trading
Advisors. The  Partnership  may  trade  up to  75  different  types  of  futures
interests,  on  both  domestic and  foreign  markets, and  may  trade additional
futures interests  as  determined by  the  Trading Advisors.  The  Partnership's
margin  commitments with respect to its  U.S. futures positions have ranged, and
are anticipated to range, between 25% and 35% of Net Assets, although in certain
circumstances, the Partnership's margin levels could deviate substantially  from
that range in the future. See "Risk Factors--Risks Relating to Futures Interests
Trading  and the Futures Interests  Markets--Futures Interests Trading is Highly
Leveraged." The Partnership's assets  deposited with DWR  will be segregated  in
accordance  with Section 4d(2) of  the CEAct and CFTC  regulations. From time to
time in  connection with  foreign  currency contracts  and foreign  futures  and
options  contracts, the Partnership's  assets may be  deposited in accounts with
non-United States banks and foreign brokers,  which are segregated on the  books
of  such banks  or brokers  for the  benefit of  DWR customers.  The Partnership
currently trades  on  the  following foreign  futures  exchanges:  the  Deutsche
Terminborse,  the Hong Kong  Futures Exchange Ltd.,  the International Petroleum
Exchange of London,
 
                                       41
<PAGE>
the London  International Financial  Futures Exchange  Ltd., the  London  Metals
Exchange, the Marche a Terme International de France, the Montreal Exchange, the
Sydney  Futures  Exchange, the  Singapore  International Monetary  Exchange, the
Tokyo International Financial Futures Exchange and the Tokyo Stock Exchange. All
such non-United States banks and foreign brokers will be qualified  depositories
pursuant  to  relevant CFTC  Advisories. Such  non-United  States banks  will be
subject to the local bank regulatory authorities and the foreign brokers will be
members of  the exchanges  on which  the futures  and option  trades are  to  be
executed  and will be subject to the regulatory authorities in the jurisdictions
in which  they operate.  The  protections provided  by such  foreign  regulatory
authorities  may  differ  significantly  from those  provided  by  United States
regulators. See "Risk Factors--Risks Relating  to Futures Interests Trading  and
the  Futures Interests  Markets--Special Risks Associated  with Forward Trading"
and "--Special Risks Associated with Trading on Foreign Exchanges."
 
    The Trading Advisors for  the Partnership are  EMC Capital Management,  Inc.
("EMC"),  Rabar Market Research, Inc. ("Rabar"), and Sunrise Capital Management,
Inc. ("Sunrise").  Subject to  certain limitations,  the Trading  Advisors  have
authority  and  responsibility for  independently  directing the  investment and
reinvestment in futures interests  of their allocated  share of Partnership  Net
Assets.  See  "The  Management Agreements."  Since  the primary  purpose  of the
Partnership is to achieve appreciation of its assets through speculative trading
in futures  interests, the  Partnership's ability  to succeed  in that  endeavor
depends  upon the success  of the respective  trading approaches of  each of the
Trading Advisors.
 
    The assets of the Partnership will  be traded pursuant to technical  trading
systems  developed  by  each  Trading Advisor.  See  "The  Trading Advisors--EMC
Capital Management,  Inc.--Description  of  EMC's  Trading  Approach,"  "--Rabar
Market  Research, Inc.--Description of Rabar's Trading Approach," and "--Sunrise
Capital Management, Inc.--Description of  Sunrise's Trading Approach." See  also
"General Description of Trading Approaches."
 
    The  Trading Advisors  will be  allocated the  net proceeds  received by the
Partnership pursuant to this offering in the following proportions:

                                                                           ---

    The Trading  Advisors  are  obligated  to  invest  in  accordance  with  the
Partnership's  trading  policies. These  trading  policies provide,  among other
things, that a Trading Advisor may commit as  margin up to, but no more than,  a
certain  percentage of funds under management. See "Trading Policies" below. The
current allocation of the Partnership's assets among the Trading Advisors as  of
August 31, 1996 is 26%, 42% and 32% for EMC, Rabar and Sunrise respectively.
    
 
    Effective  on the day of the First  Closing, DWR will credit the Partnership
at month-end with interest income as  if 80% of the Partnership's average  daily
Net  Assets for the month  were invested at a  prevailing rate for U.S. Treasury
Bills. All of  such funds  will be available  for margin  for the  Partnership's
trading.  For the purpose of  such interest payments, Net  Assets do not include
monies due to the Partnership on or with respect to forward contracts and  other
futures  interests but not actually received by it from banks, brokers, dealers,
and other persons. The Partnership's funds will either be invested together with
other customer segregated  funds or  will be held  in non-interest-bearing  bank
accounts.  In either case, the Partnership will be credited with interest at the
rate earned  by  DWR  on  its  U.S.  Treasury  Bill  investments  with  customer
segregated  funds (as if 80%  of the Partnership's assets  were invested in U.S.
Treasury Bills); DWR will retain any  interest earned in excess of the  interest
paid  to the Partnership. To  the extent that the  assets of the Partnership are
held in non-interest-bearing bank accounts,  DWR or its affiliates will  benefit
from  compensating balance treatment  in connection with  DWR's designation of a
bank or banks in which the Partnership's assets are deposited, I.E., DWR or  its
affiliates  will receive favorable loan rates from  such bank or banks by reason
of such deposits. It is not possible
 
                                       42
<PAGE>
to quantify  compensating balance  benefits  at present;  however, while  it  is
anticipated  that such benefits will exceed the interest required to be credited
to the  Partnership, it  is estimated  that they  should not  exceed 4%  of  the
Partnership's  annual average Net Assets after  such credits. To the extent that
such benefits to  DWR exceed  the interest  DWR is  obligated to  credit to  the
Partnership,  they will not be shared  with the Partnership. Notwithstanding the
foregoing, the aggregate of (i)  brokerage commissions and transaction fees  and
costs  payable  by  the  Partnership,  and  (ii)  the  net  excess  interest and
compensating balance  benefits to  DWR or  its affiliates  (after crediting  the
Partnership  with interest as described above) cannot exceed 14% annually of the
Partnership's average month-end Net Assets during each calendar year.
 
    Assets of  the Partnership  are  not commingled  with  assets of  any  other
entity.  Margin deposits and deposits  of assets with a  commodity broker do not
constitute commingling.
 
TRADING POLICIES
 
    Material changes may be made to the following Trading Policies only with the
prior written approval of  Limited Partners owning more  than 50% of Units  then
outstanding.  The General Partner will notify  the Limited Partners within seven
business days after any material change in the Partnership's Trading Policies so
approved by the Limited Partners.
 
    1. The Trading Advisors will trade only in those futures interests that have
       been approved by the General  Partner. The Partnership normally will  not
establish  new positions  in a  futures interest for  any one  contract month or
option if such additional positions would result in a net long or short position
for that futures interest requiring  as margin or premium  more than 15% of  the
Partnership's  Net  Assets.  In  addition, the  Partnership  will,  except under
extraordinary circumstances, maintain positions in futures interests in at least
two market  segments  (I.E.,  agricultural items,  industrial  items  (including
energies),  metals,  currencies,  and  financial  instruments  (including stock,
financial, and economic indexes)) at any one time.
 
    2. The Partnership  will not  acquire additional  positions in  any  futures
       interest  if such additional positions would  result in the aggregate net
long or short positions for all futures interests requiring as margin or premium
for all outstanding positions more than 66 2/3% of the Partnership's Net Assets.
Under certain market conditions, such as an abrupt increase in margins  required
by  an exchange or its clearinghouse or an inability to liquidate open positions
because of  daily price  fluctuation  limits or  both,  the Partnership  may  be
required  to commit as margin amounts in  excess of the foregoing limit. In such
event, the Trading Advisors will reduce their open positions to comply with  the
foregoing limit before initiating new positions.
 
    3. The  Partnership  will  trade  currencies and  other  commodities  in the
       interbank and forward contract markets only with banks, brokers, dealers,
and other financial institutions which the General Partner, in conjunction  with
DWR, has determined to be creditworthy. In determining the creditworthiness of a
counterparty  to a  forward contract, the  General Partner and  DWR will consult
with the Corporate Credit Department of  DWR which monitors participants in  the
interbank and forward markets with which DWR deals on a regular basis.
 
    4. The  Trading Advisors will not generally  take a position after the first
       notice day in  any futures  interest during  the delivery  month of  that
contract,  except  to match  trades to  close  out a  position on  the interbank
foreign currency or other forward markets or liquidate trades in a limit market.
 
    5. The Partnership will not employ  the trading technique commonly known  as
       "pyramiding," in which the speculator uses unrealized profits on existing
positions  in a given futures interest due to favorable price movement as margin
specifically to  buy or  sell additional  positions  in the  same or  a  related
futures  interest. Taking  into account the  Partnership's open  trade equity on
existing positions  in  determining  generally  whether  to  acquire  additional
futures  interest positions on behalf of  the Partnership will not be considered
to constitute "pyramiding."
 
                                       43
<PAGE>
    6. The Partnership  will not  purchase, sell,  or trade  securities  (except
       securities  approved by the  CFTC for investment  of customer funds). The
Partnership  may,  however,  trade  in  futures  contracts  on  securities   and
securities  indexes,  options on  such  futures contracts,  and  other commodity
options.
 
    7. The Partnership will not under any circumstances lend money to affiliated
       entities or otherwise. The Partnership will not utilize borrowings except
if  the  Partnership  purchases  or  takes  delivery  of  commodities.  If   the
Partnership  borrows money from  the General Partner  or any "affiliate" thereof
(as defined in Section 14(c) of the Limited Partnership Agreement), the  lending
entity  in such case  (the "Lender") may  not receive interest  in excess of its
interest costs, nor  may the Lender  receive interest in  excess of the  amounts
which  would  be  charged  the Partnership  (without  reference  to  the General
Partner's financial abilities  or guarantees) by  unrelated banks on  comparable
loans  for the same purpose, nor may the Lender or any affiliate thereof receive
any points or other financing charges or  fees regardless of the amount. Use  of
lines  of  credit in  connection  with its  forward  trading does  not, however,
constitute borrowing for purposes of this trading limitation.
    8. The Partnership will not permit "churning" of the Partnership's assets.

                              THE GENERAL PARTNER
 
    The  general  partner  and commodity  pool  operator of  the  Partnership is
Demeter Management Corporation, a Delaware corporation formed on August 18, 1977
to act  as a  commodity  pool operator  ("Demeter"  or the  "General  Partner").

pursuant to CFTC  Rule 4.7. The  General Partner has  served in such  capacities
since   the  inception  of  Commodity  Partners  in  February  1981  (until  its
termination in  December  1988),  the  inception of  Cornerstone  I  (until  its
termination  in December 1991), Cornerstone II,  and Cornerstone III in December
1983, the  inception of  Cornerstone  IV in  December  1986, February  1985  for
Columbia,  the  inception  of Diversified  in  November 1987,  the  inception of
Multi-Market in April 1988, the inception  of Diversified II in September  1988,
the  inception  of  Principal Guaranteed  Fund  II  in October  1988  (until its
termination in March 1996),  the inception of Principal  Guaranteed Fund III  in
October  1988  (until  its  termination in  September  1995),  the  inception of
Principal Plus in August 1989, the inception of Diversified III in May 1990, the
inception of  Portfolio Strategy  in August  1990, the  inception of  Global  in
November  1991, the inception of World  Currency in December 1992, the inception
of DWIAF in March  1994, the inception of  each of Spectrum Strategic,  Spectrum
Technical  and Spectrum Balanced  in April 1994, the  inception of Chesapeake in
November 1994 and the inception  of DWR/JWH in December  1995. As of August  31,
1996,  the General Partner had an aggregate of approximately $950 million in net
assets under management. As of August 31, 1996, there were approximately  88,000
investors  in the commodity  pools managed by Demeter  and, according to MANAGED
ACCOUNT REPORTS, as  of December 31,  1995, Demeter was  the biggest manager  of
public commodity pools in terms of assets under management, with Demeter's pools
representing a significant portion of all public commodity pools.
    
 
    The  responsibilities of the General  Partner are described under "Fiduciary
Responsibility"  and   "The   Limited   Partnership   Agreement--Management   of
Partnership  Affairs." The General Partner will  receive no compensation for its
services to the Partnership (however,  the General Partner shares office  space,
equipment and staff with DWR, which will receive commodity brokerage commissions
from  the  Partnership,  as  described  under  "Description  of  Charges  to the
Partnership--2. Dean  Witter  Reynolds  Inc."). Under  the  Limited  Partnership
Agreement,  the General Partner is required  generally to maintain its net worth
at an amount not less than 10% of the total contributions to the Partnership  by
all  the Partners thereof (including the  General Partner's contribution) and to
any other limited  partnership for which  it acts  as a general  partner by  all
partners.  In  addition  to  its current  capitalization  and  exclusive  of its
anticipated additional investment in the  Partnership, the General Partner  will
increase  its net  worth from time  to time as  may be required.  DWD intends to
contribute to the General Partner any additional capital which may be  necessary
to  permit  the  General  Partner  to  meet  such  net  worth  requirements. See
"Capitalization."
 
   
    In this connection, as  reflected in DWD's 1995  Annual Report and its  Form
10-Q  for the quarter ended June 30, 1996, DWD had total shareholders' equity of
$4,833.7 million and total assets of  $38,208.2 million as of December 31,  1995
(audited),  and total shareholders' equity of  $4,953.3 million and total assets
of $36,061.8  million as  of  June 30,  1996 (unaudited).  Additional  financial
information  regarding DWD is included in the financial statements filed as part
of such  Annual  Report and  Form  10-Q. DWD  will  provide to  investors,  upon
request,  copies of its most recent Forms 10-K, 10-Q and 8-K, as filed from time
to time with the SEC.  Such reports will be available  for review or copying  at
the  offices of  the SEC,  450 Fifth Street,  N.W., Room  1024, Judiciary Plaza,
Washington, D.C. 20549 or will  be available at no charge  by writing to DWD  at
Two World Trade Center, New York, New York 10048 (Attn: Investor Relations).

                   THE FUTURES, OPTIONS AND FORWARDS MARKETS
 
    Since  1974, the market in futures interests has undergone dramatic changes.
According to statistics provided  by the Futures  Industry Association, in  1974
the futures markets were divided 82% in agricultural products, 15% in metals, 2%
in  currencies, and 1% in lumber and  energy products; by 1995, the markets were
divided 54% in interest rates, 12% in agriculturals, 11% in stock indices, 9% in
currencies, 8% in metals, and 6% in  energy products. By 1995, over $21  billion
was invested in managed futures interests.
 
FUTURES CONTRACTS
 
    Futures  contracts are  standardized contracts  made on  domestic or foreign
exchanges which call for the future delivery of specified quantities of  various
agricultural  and  tropical  commodities,  industrial  commodities,  currencies,
financial instruments or metals at a  specified time and place. The  contractual
obligations, depending upon whether one is a buyer or a seller, may be satisfied
either by taking or making, as the case may be, physical delivery of an approved
grade  of commodity or by making an offsetting sale or purchase of an equivalent
but opposite futures contract on the same exchange prior to the designated  date
of  delivery.  As an  example of  an offsetting  transaction where  the physical
commodity is not delivered, the contractual obligation arising from the sale  of
one  contract of December 1996 wheat on a commodity exchange may be fulfilled at
any time before delivery  of the commodity  is required by  the purchase of  one
contract of December 1996 wheat on the same exchange. The difference between the
price  at which the futures contract is sold or purchased and the price paid for
the offsetting  purchase or  sale, after  allowance for  brokerage  commissions,
constitutes the profit or loss to the trader. Certain futures contracts, such as
those  for stock or other financial or  economic indices approved by the CFTC or
Eurodollar contracts, settle  in cash  (irrespective of whether  any attempt  is
made to offset such contracts), rather than delivery of any physical commodity.
 
FORWARD CONTRACTS
 
    Contracts  for  future  delivery of  certain  commodities may  also  be made
through banks or dealers pursuant to  what are commonly referred to as  "forward
contracts."  A forward  contract is  a contractual right  to purchase  or sell a
specified quantity of a commodity at or before a specified date in the future at
a specified price and, therefore, is  similar to a futures contract. In  forward
contract  trading,  a  bank  or  dealer  generally  acts  as  principal  in  the
transaction and includes its anticipated profit (the "spread" between the  "bid"
and  the "asked"  prices), and  in some  instances a  mark-up, in  the prices it
quotes for forward  contracts. Unlike futures  contracts, forward contracts  are
not  standardized contracts; rather, they are subjects of individual negotiation
between the  parties  involved.  Moreover,  there  is  no  clearinghouse  system
applicable  to forward contracts, forward contracts  are not fungible, and there
is no direct means of "offsetting" by purchase of an offsetting position on  the
same  exchange as  one can  a futures  contract. In  recent years,  the terms of
forward contracts  have become  more  standardized and  in some  instances  such
contracts  now provide a right of offset or cash settlement as an alternative to
making or taking delivery of the contract.
 
OPTIONS ON FUTURES
 
    An option on a futures contract or  on a physical commodity gives the  buyer
of the option the right to take a position at a specified price (the "striking,"
"strike,"  or "exercise" price) in the underlying futures contract or commodity.
The buyer of a "call" option acquires the  right to take a long position in  the
underlying  futures  contract or  commodity,  and the  buyer  of a  "put" option
acquires the right to take a  short position in the underlying futures  contract
or commodity.
 
    The  purchase price of an option is referred to as its "premium." The seller
(or "writer")  of  an option  is  obligated to  take  a futures  position  at  a
specified  price opposite to the option buyer  if the option is exercised. Thus,
the seller of a  call option must stand  ready to take a  short position in  the
underlying  futures contract at the striking  price if the buyer should exercise
the option. The seller of a put option,  on the other hand, must stand ready  to
take a long position in the underlying futures contract at the striking price.
 
                                       48
<PAGE>
    A  call option  on a futures  contract is  said to be  "in-the-money" if the
striking price is  below current  market levels, and  "out-of-the-money" if  the
striking  price is  above current  market levels. Similarly,  a put  option on a
futures contract is  said to be  "in-the-money" if the  striking price is  above
current  market levels,  and "out-of-the-money" if  the striking  price is below
current market levels.
 
    Options have limited life spans, usually tied to the delivery or  settlement
date  of the underlying futures contract. An option that is out-of-the-money and
not offset  by the  time it  expires becomes  worthless. On  certain  exchanges,
in-the-money  options are automatically exercised  on their expiration date, but
on others unexercised  options simply  become worthless  after their  expiration
date.  Options usually trade at a premium above their intrinsic value (I.E., the
difference between the market price for the underlying futures contract and  the
striking  price),  because  the  option trader  is  speculating  on  (or hedging
against) future movements in the price of the underlying contract. As an  option
nears  its expiration date,  the market and intrinsic  value typically move into
parity. The  difference  between an  option's  intrinsic and  market  values  is
referred to as the "time value" of the option.
 
    The  use  of  interrelated  options and  futures  positions  can  provide an
additional means of  risk management  and permit a  trader to  retain a  futures
position  in the hope of additional appreciation  in that position, while at the
same time allowing the trader to limit the possible adverse effects of a decline
in the position's value.
 
    Successful futures options trading requires many of the same skills as  does
successful  futures  trading. However,  since specific  market movements  of the
underlying futures contract or commodity must be predicted accurately, the risks
involved are somewhat different. For example, if the Partnership buys an  option
(either to sell or buy a futures contract or commodity), it will pay a "premium"
representing  the market value and time value of the option. Unless the price of
the futures contract or commodity underlying  the option changes and it  becomes
profitable  to exercise or offset the  option before it expires, the Partnership
may lose the entire amount of such premium. Conversely, if the Partnership sells
an option (either to sell  or buy a futures contract  or commodity), it will  be
credited  with the premium but will have to deposit margin due to its contingent
liability to take or  deliver the futures contract  or commodity underlying  the
option  in  the event  the option  is  exercised. Traders  who sell  options are
subject to the entire  loss which occurs in  the underlying futures position  or
commodity  (less  any premium  received). The  ability to  trade in  or exercise
options may be restricted  in the event that  trading in the underlying  futures
contract or commodity becomes restricted.
 
HEDGERS AND SPECULATORS
 
    The  two broad classes of persons  who trade futures interests contracts are
"hedgers" and  "speculators."  Commercial  interests,  including  farmers,  that
market  or process commodities and financial institutions that market or deal in
commodities  (including,  for  example,  interest  rate  sensitive  instruments,
foreign  currencies and  stock portfolios)  and which  are exposed  to exchange,
interest rate and stock market risks, may use the commodities markets  primarily
for  hedging. Hedging is a protective procedure designed to minimize losses that
may occur because of price fluctuations occurring, for example, between the time
a merchandiser or processor makes a contract  to buy or sell a raw or  processed
commodity  at a  certain price and  the time  he must perform  the contract. The
commodity markets enable the hedger to  shift the risk of price fluctuations  to
the speculator. The speculator risks his capital with the hope of making profits
from  price fluctuations in futures interests contracts. Speculators rarely take
delivery of commodities,  but generally  close out their  positions by  entering
into  offsetting purchases or sales of  contracts. Since the speculator may take
either a long or short position in  the commodities markets, it is possible  for
him  to make profits or incur losses regardless of whether prices go up or down.
Trading by the Partnership will be for speculative rather than hedging purposes.
 
COMMODITY EXCHANGES
 
    Commodity  exchanges  provide  centralized  market  facilities  for  trading
futures  contracts and options (but not forward contracts) relating to specified
commodities, indices and other intangibles. Members of, and trades executed  on,
a   particular   exchange  are   subject  to   the   rules  of   that  exchange.
 
                                       49
<PAGE>
Among the principal  exchanges in  the United States  are the  Chicago Board  of
Trade,  the Chicago  Mercantile Exchange  (including the  International Monetary
Market), the New York Mercantile Exchange, the Commodity Exchange, Inc. and  the
Coffee, Sugar and Cocoa Exchange.
 
    Each  of  the commodity  exchanges in  the United  States has  an associated
"clearinghouse." Once trades between members of an exchange have been confirmed,
the clearinghouse  becomes  substituted  for  each  buyer  and  each  seller  of
contracts traded on the exchange and, in effect, becomes the other party to each
trader's  open position in the  market. Thereafter, each party  to a trade looks
only  to  the  clearinghouse   for  performance.  The  clearinghouse   generally
establishes  some  sort of  security  or guarantee  fund  to which  all clearing
members of the exchange must contribute;  this fund acts as an emergency  buffer
which  enables  the clearinghouse,  at  least to  a  large degree,  to  meet its
obligations with regard to  the "other side" of  an insolvent clearing  member's
contracts.  Furthermore, clearinghouses require margin deposits and continuously
mark positions to market  to provide some assurance  that their members will  be
able  to fulfill their contractual obligations.  Thus, a central function of the
clearinghouses is  to ensure  the  integrity of  trades, and  members  effecting
futures  transactions on an organized exchange need not worry about the solvency
of the party on the  opposite side of the  trade; their only remaining  concerns
are  the respective solvencies of their  commodity broker and the clearinghouse.
The exchanges also impose speculative position limits and other restrictions  on
customer  positions to help  ensure that no  single trader can  amass a position
that would have a major impact on market prices.
 
    Commodity exchanges in the United States and their clearinghouses are  given
reasonable  latitude  in  promulgating  rules  and  regulations  to  control and
regulate their members. Examples of regulations by exchanges and  clearinghouses
include  the  establishment of  initial margin  levels,  size of  trading units,
contract specifications, speculative position limits and daily price fluctuation
limits. The CFTC reviews all such  rules (other than those relating to  specific
margin  levels for futures, as  opposed to options) and  can disapprove or, with
respect to certain of such rules, require the amendment or modification thereof.
 
    Foreign commodity exchanges  differ in  certain respects  from their  United
States  counterparts. In  contrast to  United States  exchanges, certain foreign
exchanges are "principals' markets,"  where trades remain  the liability of  the
traders  involved, and the  exchange does not become  substituted for any party.
See  "The  Futures,   Options  and  Forward   Markets--Regulations"  and   "Risk
Factors--Risks  Relating to Futures Interests  Trading and the Futures Interests
Markets--Special Risks Associated with Trading on Foreign Exchanges."
 
SPECULATIVE POSITION LIMITS
 
    The CFTC and the United States commodity exchanges have established  limits,
referred  to  as  "speculative position  limits"  or "position  limits,"  on the
maximum net long or net short speculative position which any person or group  of
persons  (other than a  hedger, which the  Partnership is not)  may hold, own or
control in  futures  interests  contracts. Among  the  purposes  of  speculative
position  limits is  to prevent  a "corner"  on a  market or  undue influence on
prices by any single trader  or group of traders.  The CFTC has jurisdiction  to
establish  position limits with  respect to all  commodities and has established
position limits for all agricultural commodities. In addition, the CFTC requires
each United States exchange to submit position limits for all commodities traded
on  such  exchange  for  approval  by  the  CFTC.  Certain  exchanges  or  their
clearinghouses  also set limits on the total net positions that may be held by a
commodity broker, such  as DWR. However,  position limits do  not apply to  many
currency futures contracts, and, in general, no position limits are in effect in
bank  or  dealer forward  contract trading  or in  trading on  foreign commodity
exchanges, although the principals with which the Partnership may trade in  such
markets  may  impose such  limits  as a  matter  of credit  policy.  The futures
interests positions of the Partnership are not, and will not be, attributable to
Limited Partners with respect  to their own futures  interests trading, if  any,
for purposes of position limits.
 
                                       50
<PAGE>
DAILY LIMITS
 
    Most  United States commodity exchanges (but generally not foreign exchanges
or banks or dealers in the case of forward contracts) normally limit the  amount
of  fluctuation in futures interests contract prices during a single trading day
by regulation. These regulations  specify what are referred  to as "daily  price
fluctuation  limits" or more commonly "daily limits." The daily limits establish
the maximum amount that the price of a commodity contract may vary either up  or
down  from the previous  day's settlement price.  Once the daily  limit has been
reached in a  particular futures  interest, no  trades may  be made  at a  price
beyond the limit. This can create liquidity problems.
 
REGULATIONS
 
    Commodity exchanges in the United States are subject to regulation under the
CEAct  by the CFTC, the governmental agency having responsibility for regulation
of commodity exchanges and futures interests contract trading conducted thereon.
The function  of  the CFTC  is  to implement  the  objectives of  the  CEAct  of
preventing  price manipulation  and excessive speculation  and promoting orderly
and efficient  markets.  Such  regulation, among  other  things,  provides  that
trading  in  futures  interests contracts  must  be on  exchanges  designated as
"contract markets," and that all  trading on such exchanges  must be done by  or
through exchange members.
 
    The  CFTC  possesses exclusive  jurisdiction to  regulate the  activities of
"commodity trading  advisors" and  "commodity pool  operators" and  has  adopted
regulations with respect to certain of such persons' activities. Pursuant to its
authority,  the CFTC  requires a  commodity pool  operator (such  as the General
Partner) to keep accurate, current and orderly records with respect to each pool
it operates. The CFTC may suspend the registration of a commodity pool  operator
if  the  CFTC finds  that the  operator  has violated  the CEAct  or regulations
thereunder and  in  certain  other  circumstances.  Suspension,  restriction  or
termination  of the General Partner's registration  as a commodity pool operator
would prevent the General Partner, until such time (if any) as such registration
were to be reinstated, from managing, and might result in a termination of,  the
Partnership.  The CEAct  gives the  CFTC similar  authority with  respect to the
activities of commodity trading advisors, such  as the Trading Advisors. If  the
registration  of a  Trading Advisor  as a commodity  trading advisor  were to be
terminated, restricted or suspended, the Trading Advisor would be unable,  until
such time (if any) as such registration were to be reinstated, to render trading
advice  to the  Partnership. The Partnership  itself is not  registered with the
CFTC in any capacity.
 
    The CEAct requires all "futures commission merchants," such as DWR, to  meet
and  maintain specified  fitness and financial  requirements, segregate customer
funds from proprietary funds and account separately for all customers' funds and
positions, and to maintain specified books and records open to inspection by the
staff of the CFTC.  The CFTC has similar  authority over "introducing  brokers,"
I.E.,  persons who  solicit or accept  orders for  trades but who  do not accept
margin deposits for  the execution  of trades.  The Partnership  has no  present
intention  of using any introducing brokers in its trading. The CEAct also gives
the states certain powers to enforce  its provisions and the regulations of  the
CFTC.
 
    The  fact of CFTC registration  of the General Partner,  DWR and the Trading
Advisors does not imply that the CFTC has passed on or approved this offering or
their qualifications to act as described in the Prospectus.
 
    Limited Partners  are  afforded certain  rights  for reparations  under  the
CEAct.  Limited Partners may also be able  to maintain a private right of action
for certain violations of the CEAct. The CFTC has adopted rules implementing the
reparation provisions of  the CEAct  which provide that  any person  may file  a
complaint  for a  reparations award  with the  CFTC for  violation of  the CEAct
against  a  floor  broker,  futures  commission  merchant,  introducing  broker,
commodity  trading  advisor,  commodity  pool  operator,  and  their  respective
associated persons.
 
    Pursuant to authority in the CEAct,  the NFA has been formed and  registered
with  the CFTC as a  "registered futures association." At  the present time, the
NFA is the only non-exchange self-regulatory
 
                                       51
<PAGE>
organization for  commodities  professionals. NFA  members  are subject  to  NFA
standards  relating to fair  trade practices, financial  condition, and consumer
protection. As the  self-regulatory body  of the commodities  industry, the  NFA
promulgates   rules  governing  the  conduct   of  commodity  professionals  and
disciplines those professionals who do not comply with such standards. The  CFTC
has  delegated  to  the NFA  responsibility  for the  registration  of commodity
trading  advisors,  commodity  pool  operators,  futures  commission  merchants,
introducing  brokers and their respective  associated persons and floor brokers.
DWR, the General Partner and  the Trading Advisors are  members of the NFA  (the
Partnership itself is not required to become a member of the NFA).
 
    The  above-described regulatory structure  may be modified  (or repealed) by
rules and regulations promulgated by the CFTC or by legislative changes  enacted
by Congress.
 
    The CFTC has no authority to regulate trading on foreign commodity exchanges
and  markets. The CFTC has, however, adopted  rules relating to the marketing of
foreign futures contracts and options in  the United States. These rules  permit
commodity  options traded  only on certain  foreign exchanges to  be offered and
sold in the  United States.  See "Risk  Factors--Risks Relating  to the  Futures
Interests Trading and the Futures Interests Markets."
 
MARGINS
 
    "Initial"  or "original" margin is the minimum  amount of funds that must be
deposited by a  trader with his  commodity broker in  order to initiate  futures
trading  or to  maintain an  open position  in futures  contracts. "Maintenance"
margin is the amount  (generally less than initial  margin) to which a  trader's
account  may decline before he must  deliver additional margin. A margin deposit
is like  a  cash  performance  bond. It  helps  assure  the  commodity  trader's
performance  of the commodity  futures contracts he  purchases or sells. Futures
contracts are customarily bought and sold on margins that represent a very small
percentage (ranging  upward from  less than  2%) of  the purchase  price of  the
underlying   commodity  being  traded.  Because   of  such  low  margins,  price
fluctuations occurring in the futures markets may create profits and losses that
are greater, in  relation to the  amount invested, than  are customary in  other
forms  of investment  or speculation. The  minimum amount of  margin required in
connection with a particular futures  contract is set from  time to time by  the
exchange on which such contract is traded, and may be modified from time to time
by  the  exchange during  the  term of  the  contract. See  "Risk Factors--Risks
Relating to Futures Interests Trading and the Futures Interests Markets."
 
    Brokerage firms carrying accounts for  traders in futures contracts may  not
accept  lower, and generally  require higher, amounts  of margin as  a matter of
policy in order to  afford further protection for  themselves. DWR will  require
the Partnership to make margin deposits equal to the exchange minimum levels for
all  futures contracts. This requirement may be altered from time to time at the
discretion of DWR.
 
    Trading in the currency forward contract market does not require margin, but
generally does require the extension of credit by a bank or dealer with which  a
person  trades. Since the Partnership's trading  will be conducted with DWR, the
Partnership will be able  to take advantage of  DWR's credit lines with  several
participants  in the interbank  market. The General  Partner does not anticipate
that banks and dealers with which DWR and the Partnership may trade will require
margin with respect to their trading of currencies.
 
    When a trader purchases  an option, there is  no margin requirement. When  a
trader  sells an option, on the other hand,  he is required to deposit margin in
an amount  determined by  the margin  requirements established  for the  futures
contract  underlying the option, and, in addition, an amount substantially equal
to the current premium  for the option. The  margin requirements imposed on  the
writing   of  options,  although  adjusted   to  reflect  the  probability  that
out-of-the-money options will not be exercised, can in fact be higher than those
imposed  in  dealing  in  the  futures  markets  directly.  Complicated   margin
requirements  apply to  "spreads" and  "conversions," which  are complex trading
strategies in which a trader acquires  a mixture of related futures and  options
positions.
 
                                       52
<PAGE>
    Margin  requirements are  computed each day  by a trader's  broker. When the
market value of a particular open  futures contract position changes to a  point
where  the margin on deposit does not satisfy maintenance margin requirements, a
margin call is  made by  the broker.  If the  margin call  is not  met within  a
reasonable time, the broker may close out the trader's position. With respect to
the  Partnership's  trading,  the  Partnership,  and  not  its  Limited Partners
personally, is subject to margin calls.
 
                   GENERAL DESCRIPTION OF TRADING APPROACHES
 
INTRODUCTION
 
    The investment objective of the  Partnership is capital appreciation of  its
assets  through  speculative  trading in  futures  interests.  The Partnership's
ability to  succeed in  this endeavor  depends  largely on  the success  of  the
trading  approaches  utilized  on  behalf of  such  Partnership  by  the Trading
Advisors. The following  is a brief  description of general  approaches used  in
trading  futures  interests, followed  by specific  information relating  to the
Trading Advisors.
 
SYSTEMATIC AND DISCRETIONARY
 
    Trading advisors may be classified as either systematic or discretionary.
 
    A systematic  trader  will  generally  rely to  some  degree  on  judgmental
decisions  concerning, for example, what markets to follow and futures interests
to trade, when to liquidate  a position in a contract  which is about to  expire
and  how large  a position  to take in  a particular  futures interest. However,
although  these  judgmental  decisions  may  have  a  substantial  effect  on  a
systematic  trading advisor's  performance, his  primary reliance  is on trading
programs or  models which  generate  trading signals.  The systems  utilized  to
generate  trading  signals are  changed from  time  to time  (although generally
infrequently), but the trading instructions generated by the systems being  used
are   followed  without  significant   additional  analysis  or  interpretation.
Discretionary traders, on the other hand, while they may utilize market  charts,
computer  programs and  compilations of quantifiable  fundamental information to
assist them in making trading decisions, make trading decisions on the basis  of
their  own judgment and trading experience, not  on the basis of trading signals
generated by any program or model.
 
    Each approach involves certain inherent  risks. Systematic traders may  fail
to  capitalize  on  market  trends  which  their  systems  would  otherwise have
exploited due to judgmental  decisions made by them  in the context of  applying
their  generally mechanical trading systems. Discretionary traders, on the other
hand, may decide to make trades which would not have been signaled by a  trading
system  and which result in substantial  losses. Furthermore, any trading system
or trader may  suffer substantial  losses by misjudging  the market.  Systematic
traders  tend  to  rely  more on  computerized  programs  than  do discretionary
traders, and some consider  the prospect of  disciplined trading, which  largely
removes  the  emotion  of  the  individual  trader  from  the  trading  process,
advantageous. In addition, due to their use of computers, systematic traders are
generally able to incorporate more data into a particular trading decision  than
can  discretionary  traders.  However,  when  fundamental  factors  dominate the
market, trading  systems  may  suffer  rapid and  severe  losses  due  to  their
inability  to respond to such factors until  the reversal of trading signals, by
which time a  precipitous price change  may already be  in progress,  preventing
liquidation  at anything but substantial  losses. The trading approaches applied
by the Trading Advisors are systematic, although subjective judgment is used  in
the application of their systematic programs.
 
TECHNICAL AND FUNDAMENTAL ANALYSIS
 
    In  addition to  being distinguished  from one  another by  the criterion of
whether they  trade  systematically  or  on the  basis  of  their  discretionary
evaluations  of the markets, trading advisors  are also distinguished as relying
on either "technical" or "fundamental" analysis, or on a combination of the two.
Systematic traders tend to rely on technical analysis, because the data relevant
to such analysis  is more susceptible  to being isolated  and quantified to  the
extent  necessary to be successfully incorporated into a program or mathematical
model   than   is   most   "fundamental"   information,   but   there   is    no
 
                                       53
<PAGE>
inconsistency  in attempting to trade systematically on the basis of fundamental
analysis. The fundamental  information which  can be evaluated  by a  formalized
trading  system is, however, limited to some extent in that it generally must be
quantifiable in order to be processed by such a system.
 
    Technical analysis is not  based on anticipated  supply and demand  factors;
instead,  it is  based on  the theory  that the  study of  the futures interests
markets themselves will provide  a means of anticipating  prices in the  future.
Technical  analysis operates on the theory that market prices at any given point
in time  reflect  all  known factors  affecting  the  supply and  demand  for  a
particular  futures interest.  Consequently, technical  analysis focuses  not on
evaluating  those  factors  directly  but  on  an  analysis  of  market   prices
themselves,  theorizing that a detailed analysis  of, among other things, actual
daily, weekly and monthly price  fluctuations, volume variations and changes  in
open  interest is the most  effective means of attempting  to predict the future
course of price movements.
 
    Fundamental analysis, in contrast, is based on the study of factors external
to the trading markets that affect the supply and demand of a particular futures
interest in  an attempt  to  predict future  price  levels. Such  factors  might
include  weather,  the economy  of  a particular  country,  government policies,
domestic  and  foreign  political  and  economic  events,  and  changing   trade
prospects. Fundamental analysis theorizes that by monitoring relevant supply and
demand  factors  for a  particular commodity,  a state  of current  or potential
disequilibrium of  market  conditions may  be  identified  that has  yet  to  be
reflected  in the  price level  of that  futures interest.  Fundamental analysis
assumes that  markets are  imperfect, that  information is  not  instantaneously
assimilated or disseminated, and that econometric models can be constructed that
generate   equilibrium  prices  that  may   indicate  that  current  prices  are
inconsistent with underlying economic  conditions and will, accordingly,  change
in the future.
 
    The  trading programs of EMC and Sunrise are pure technical systems. Rabar's
trading program is  also a  technical system  but incorporates  analysis of  key
fundamental factors, particularly for risk control factors.
 
TREND-FOLLOWING
 
    "Trend-following"  trading  advisors gear  their trading  approaches towards
positioning themselves to take advantage of major price movements, as opposed to
traders who  seek to  achieve  overall profitability  by making  numerous  small
profits on short-term trades, or through arbitrage techniques. "Trend-following"
trading  advisors assume that  most of their trades  will be unprofitable. Their
objective is  to make  a few  large  profits, more  than offsetting  their  more
numerous  but smaller losses,  from capitalizing on  major trends. Consequently,
during  periods  when   no  major   price  trends   develop  in   a  market,   a
"trend-following" trading advisor is unlikely to develop any meaningful profits.
Trend-following is a major element of each Trading Advisor's technical analysis.
 
RISK CONTROL TECHNIQUES
 
    As will be apparent from the following descriptions of the Trading Advisors'
trading  approaches, an  important aspect  of any  speculative futures interests
strategy relates to  the control  of losses, not  only the  ability to  identify
profitable  trades. Unless it is  possible to avoid major  drawdowns, it is very
difficult to achieve long-term profitability.
 
    Trading advisors  often  adopt  fairly rigid  "risk  management"  or  "money
management" principles. Such principles typically restrict the size of positions
which  will be taken, as well as establishing "stop-loss" points at which losing
positions must  be liquidated.  It  is important  for prospective  investors  to
recognize  that no risk control  technique is "fail safe"  and can not, in fact,
assure that major  drawdowns will be  avoided. Not only  do estimates of  market
volatility  themselves require judgmental input, but market illiquidity also can
make it impossible  for an  account to liquidate  a position  against which  the
market  is moving  strongly, whatever  risk management  principles are utilized.
Similarly, unless  a "trend-following"  trading advisor  trades profitably,  the
losses  incurred in  the course  of taking an  initial position  in a particular
futures interest  can  quickly  accumulate  into a  major  drawdown.  A  trading
advisor's  risk management  principles should,  accordingly, be  seen more  as a
discipline applied to its trading in  highly speculative markets rather than  as
an effective protection against loss.
 
                                       54
<PAGE>
    Not  only are some  methods proprietary and confidential,  but they are also
continually evolving. Prospective investors and Limited Partners will  generally
not  be informed of a change in a Trading Advisor's trading approach, unless the
General Partner considers such change to be material.
 
    In addition to the  continually changing character  of trading methods,  the
futures  interests  markets themselves  are  continually changing.  Each Trading
Advisor may, in its sole discretion, elect to trade certain futures interests to
the exclusion of others  in its programs, depending  upon the Trading  Advisors'
view of the markets.
 
                              THE TRADING ADVISORS
 
INTRODUCTION
 
    The  Partnership  has entered  into Management  Agreements with  EMC Capital
Management, Inc. ("EMC"),  Rabar Market  Research, Inc.  ("Rabar"), and  Sunrise
Capital  Management,  Inc. ("Sunrise")  (collectively, the  "Trading Advisors"),
pursuant to which  the Trading  Advisors will, subject  to certain  limitations,
have  authority and responsibility for directing the investment and reinvestment
in futures interests  of their allocated  share of Partnership  Net Assets.  See
"The  Management Agreements." Since the primary purpose of the Partnership is to
achieve appreciation  of  its  assets through  speculative  trading  in  futures
interests,  the Partnership's  ability to succeed  in that  endeavor will depend
upon the success  of the respective  trading approaches of  each of the  Trading
Advisors.
 
    The  General  Partner  has  extensive  experience  in  the  organization  of
commodity pools and  the evaluation  and selection of  trading advisors,  having
operated  28  commodity pools  since 1978.  The  General Partner's  objective in
selecting the trading advisors  for the Partnership was  to attempt to obtain  a
combination  of trading advisors employing aggressive trading strategies coupled
with strict  risk  control  measures,  which would  be  able  to  capitalize  on
profitable  trends while providing substantial  protection against major losses.
The selection of  the Trading Advisors  was influenced by  a number of  factors,
among  which  was the  General Partner's  evaluation  of each  Trading Advisor's
historical performance, including  the markets traded  by each Trading  Advisor,
its  ability to control  risk, the amount  of equity previously  managed by each
Trading Advisor,  and  a desire  to  seek  a complementary  mixture  of  trading
approaches and markets traded.
 
    The  General Partner has, to date, allocated the Partnership's Net Assets to
the management  of the  Trading Advisors  in equal  proportions and  anticipates
allocating the proceeds of this offering equally among the Trading Advisors. The
General Partner, however, has the discretion to reallocate Net Assets among EMC,
Rabar,   and   Sunrise   at   any   subsequent   date.   See   "The   Management
Agreements--Allocation and Reallocation of the Partnership's Net Assets."
 
    The following descriptions of the Trading Advisors, their respective trading
systems, methods, and strategies and their respective principals are general and
are not intended to be exhaustive.  Certain Trading Advisors may have chosen  to
refer  to specific  aspects of  their trading  systems, methods,  and strategies
which may be applicable to other Trading  Advisors which did not choose to  make
explicit  reference to such  specific characteristics of  their trading systems,
methods,  and  strategies.  As  a   consequence,  contrasts  in  the   following
descriptions  may not,  in fact, indicate  a substantive  difference between and
among the trading systems, methods, and strategies in question.
 
EMC CAPITAL MANAGEMENT, INC.
 
    EMC is an  Illinois corporation,  registered with  the CFTC  as a  commodity
trading  advisor and  commodity pool operator.  EMC was  incorporated in January
1988 for  the  purpose  of  acting  as a  commodity  trading  advisor,  and  was
registered  with the CFTC as a commodity trading advisor in May of 1988 and as a
commodity pool operator in February 1991. Elizabeth Cheval is the sole  director
of EMC, although Ms. Cheval's stock ownership in EMC is held through a revocable
trust  of which she  is the sole beneficiary  and sole trustee.  Ms. Cheval is a
member   of    the    NFA    as    is    EMC    in    its    capacity    as    a
 
                                       55
<PAGE>
commodity  pool operator and commodity trading advisor. The business address and
telephone number of  EMC are  2201 Waukegan  Road, Suite  West 240  Bannockburn,
Illinois  60015  and (847)  267-8700.  EMC is  not  affiliated with  the General
Partner, DWR, Rabar or Sunrise.
 
    The principals of EMC are Elizabeth A. Cheval and Jeffrey D. Izenman.
 
    Elizabeth A. Cheval, age 39,  is the Chairman and  sole Director of EMC.  In
1984  Ms. Cheval was selected with nine  other individuals by Richard J. Dennis,
Jr., a speculative  trader of  futures and options,  to trade  for his  personal
account.  As  his  employee, Ms.  Cheval  received extensive  training  from Mr.
Dennis,  who  personally  supervised   her  trading.  In   1986  she  became   a
self-employed  trader of client  equity, and continued to  trade for accounts of
family members  of Mr.  Dennis until  May of  1988 when  Mr. Dennis  elected  to
discontinue  his trading program.  Prior to working with  Mr. Dennis, Ms. Cheval
worked with A.G.  Becker, a  Chicago-based brokerage firm,  advising traders  of
mortgage-backed  securities on  hedging in the  futures markets.  Ms. Cheval has
traded futures since 1983, when she began trading financial futures for her  own
account.  Ms. Cheval received a B.A.  in Mathematics from Lawrence University in
1978.
 
    Jeffrey D. Izenman, age 39, is the  President of EMC having joined the  firm
in  that capacity in September, 1994. Since  January, 1995, Mr. Izenman has also
been a member of the Board of  Directors of the Managed Futures Association  and
is  a  member of  the Association's  four person  executive committee.  Prior to
joining EMC, Mr. Izenman was a partner in the law firm of Katten Muchin &  Zavis
from  October, 1988 through August,  1994, and an associate  with that firm from
September,  1982  through   September,  1988.  There   he  specialized  in   the
representation  of commodity trading advisors (including EMC) and commodity pool
operators as well as  securities investment advisers  and hedge fund  operators.
Mr. Izenman received his JD degree from the University of Michigan Law School in
May,  1982 and  a B.S. in  Accountancy from  the University of  Illinois in May,
1979.
 
    At this time, neither EMC  nor Ms. Cheval or Mr.  Izenman trades for its  or
their own account, but each reserves the right to do so in the future. If either
EMC  or Ms. Cheval  or Mr. Izenman engage  in such trading,  records will not be
available for inspection  by Limited Partners.  It should be  noted that EMC  is
currently  the CPO and CTA  of the EMC Premier Fund,  L.P., a commodity pool for
which EMC acts as the general partner. Ms. Cheval is currently a limited partner
in two commodity pools for which EMC is a trading advisor. Neither EMC or any of
its principals own any Units of the Partnership.
 
    There have  been  no material  administrative,  civil, or  criminal  actions
pending, on appeal or concluded against EMC or any of its principals.
 
    DESCRIPTION OF EMC'S TRADING APPROACH
 
    EMC  currently invests client assets solely through its Diversified Program.
The Diversified Program is being utilized for the Partnership. The exact  nature
of  EMC's  investment programs  is proprietary  and confidential.  The following
description, which is of necessity general and is not intended to be exhaustive,
is of The Diversified Program only.
 
    EMC's investment strategy  is technical rather  than fundamental in  nature,
I.E.,  it is developed from analysis of  patterns of actual monthly, weekly, and
daily price movements  and is not  based on analysis  of fundamental supply  and
demand factors, general economic factors or anticipated world events. EMC relies
on  historical  analysis of  these price  patterns  to interpret  current market
behavior  and  to  evaluate  technical  indicators  for  trade  initiations  and
liquidations.
 
    EMC's   investment  strategy  is  trend-following  in  that  initiations  of
positions in a  particular market are  generally in the  direction of the  price
trend   in   that  market.   Liquidations  of   positions  also   are  generally
trend-following, but can  be countertrend  if EMC  believes the  trend has  been
exhausted.
 
    EMC  employs  an  investment strategy  which  utilizes a  number  of systems
simultaneously. The  strategy is  diversified  in that  EMC follows  over  fifty
futures interests and often invests in more than ten at one time.
 
                                       56
<PAGE>
    Although the specific types of futures interest contracts, including but not
limited  to futures contracts,  options on futures  contracts, forward contracts
and cash commodities,  to be invested  in through the  Diversified Program  will
vary  from time to time, at the present time, EMC principally invests in futures
interests for its clients. Examples of futures interests for which contracts are
now invested in by EMC include, but are not necessarily limited to, precious and
base metals,  U.S. and  foreign financial  instruments, stock  indices,  foreign
currencies,  grains and grain  products, energy products such  as crude oil, and
soft commodities such as cocoa, orange juice, sugar, and coffee. EMC may  invest
in  other  futures  interests  in  the future.  EMC  may  trade  certain futures
interests for some clients which it does not trade for the Partnership.
 
    EMC also will invest in currency  forward contracts on the foreign  exchange
markets.  These markets generally have provided liquidity for the purpose of the
trading of  foreign currencies.  Trading in  foreign exchange  contracts is  not
regulated  by the CFTC and such contracts are  not traded on or guaranteed by an
exchange or its clearing house. Rather,  banks and dealers act as principals  in
the  forward contract markets. Therefore,  trading in foreign exchange contracts
is not subject to the same  protections, either regulatorily or financially,  as
is trading in futures contracts.
 
    EMC  also  may engage  in  transactions in  physical  commodities, including
exchange for  physical  transactions. An  exchange  for physical  ("EFP")  is  a
transaction  permitted under  the rules of  many futures exchanges  in which two
parties holding futures positions may  close out their positions without  making
an  open, competitive trade  on the exchange.  Generally, the holder  of a short
futures position buys the physical commodity, while the holder of a long futures
position sells the physical commodity. The prices at which such transactions are
executed are negotiated between the parties, and such prices may, under  certain
circumstances,   vary  significantly  from  the   actual  prices  at  which  the
transactions are traded on the relevant exchanges.
 
    The futures interest contracts typically traded have been chosen for,  among
other  things, their historical  performance and for  their customary liquidity.
EMC may  frequently  invest, however,  in  less liquid  markets.  EMC  generally
commits  approximately  20% to  50% of  an  account's equity  as margin  on open
positions.
 
    EMC believes that  the development  of a  futures investment  strategy is  a
continual  process.  As  a result  of  further  analysis and  research  into the
performance of EMC's methods, changes  have been made from  time to time in  the
specific  manner in which  these investment methods  evaluate price movements in
various commodities, and it is likely that similar revisions will be made in the
future. As a result  of such modifications, the  investment methods that may  be
used  by EMC in the future might differ from those presently being used. Because
EMC's methods are proprietary and confidential,  the General Partner may not  be
aware of such changes in EMC's investment methods.
 
    Initially,  EMC's  risk management  will be  dictated by  the amount  of its
allocated share of Partnership Net Assets. However, as profits are generated  or
losses  are incurred,  the risk  management techniques  employed by  EMC for the
Partnership will be modified. For example, as its allocated share of Partnership
Net Assets is increased due to both realized and unrealized trading profits, EMC
may increase  the amount  of leverage  used  and increase  the risk  taken  with
realized profits.
 
    If   possible  within  existing  market   conditions,  EMC  adheres  to  the
requirements of a money management system which determines and limits the equity
committed to each trade, each commodity and each group of commodities, and  sets
optimal  stop-losses for each  trade and each account.  The level of liquidation
determined by this money management system can override liquidations  determined
by technical indicators, especially when an account has not generated profits or
is experiencing losses.
 
    Under  EMC's investment  method, profits,  if any,  are generated  by only a
small percentage  of  the  total number  of  trades  placed. As  a  result,  the
Partnership's  Net Assets allocated to EMC  will experience times of substantial
drawdowns. These drawdowns may be as high as 50% or more of the amount of  funds
initially  allocated to EMC. In  addition, from time to  time EMC may experience
drawdowns well  in  excess of  50%  from  peak levels  of  account  performance.
Substantial drawdowns do not, however,
 
                                       57
<PAGE>
necessarily  indicate a failure in the investment strategy, but rather are to be
expected under  the  EMC  program. Prospective  investors  must,  therefore,  be

    Rabar  is an  Illinois corporation  which is registered  with the  CFTC as a
commodity trading advisor and a commodity pool  operator and is a member of  the
NFA  in both such capacities. Paul Rabar  is the President and sole principal of
Rabar. Rabar was  originally named  Rainbow Market  Research, Inc.  when it  was
incorporated  in November 1986. It was registered as a commodity trading advisor
and a  commodity  pool  operator  in  June  1988.  Rabar  has  managed  accounts
continuously  since July  1988. Its name  was changed to  Rabar Market Research,
Inc. in January 1989. The business address and telephone number of Rabar are  10
Bank  Street, Suite 830,  White Plains, New York  10606-1933 and (914) 682-8363.
Rabar is not affiliated with the General Partner, DWR, EMC or Sunrise.
 
    Paul Rabar, age 40, first traded commodity futures in 1980. He worked as  an
account executive at E.F. Hutton from 1981 to 1983 and then at Clayton Brokerage
until  1984. In 1985 and 1986 he traded commodity futures for Richard J. Dennis,
Jr., a speculative trader of  futures and options. In  1987 and 1988 until  May,
Mr.  Rabar independently  managed an account  for another  speculative trader of
futures and options. He traded his own account from May 1988 until January 1989,
when he invested in a  futures fund to which Rabar  is one of the advisors.  Mr.
Rabar  is a graduate of the New England Conservatory of Music. He did additional
work--primarily in science and mathematics--at  Harvard University, and in  1979
and 1980 was an assistant instructor of physics there.
 
    Rabar  is the commodity pool operator of,  and serves as the trading advisor
to, Rabar Futures Fund, L.P.,  a private commodity pool.  Mr. Rabar is also  the
sole  shareholder  of Rabar  International  Management, Ltd.,  a  Cayman Islands
corporation, which operates Rabar International Futures Fund, L.P., a  commodity
pool organized in the Cayman Islands (that is not open to U.S. investors). Rabar
is the trading advisor of Rabar International Futures Fund, L.P.
 
    It  should be noted  that Rabar and/or  Mr. Rabar currently,  and may in the
future, invest in commodity  pools that are advised  by Rabar. However,  neither
Rabar nor Mr. Rabar own any Units of the Partnership.
 
   
    Rabar  does not currently trade an account for  itself, but may do so in the
future. Mr. Rabar, however,  currently trades a  personal account. Such  trading
occurs  only in markets which are considered  too illiquid to trade on behalf of
clients, although Mr. Rabar may trade in other markets in the future. Records of
Rabar's and  Mr. Rabar's  personal trading  will not  be open  to inspection  by
Limited Partners.
    
 
    There  have  been no  material  administrative, civil,  or  criminal actions
pending, on appeal or concluded against Rabar or Mr. Rabar.
 
    DESCRIPTION OF RABAR'S TRADING APPROACH
 
    Rabar's objective is  to achieve  appreciation of  the Partnership's  assets
which it is allocated through speculative trading of futures interest contracts,
including  but not limited to domestic and foreign futures contracts and options
on futures  contracts  and forward  contracts.  Rabar primarily  trades  futures
contracts  for  its existing  clients,  although Rabar  may  also engage  in the
trading of forward or spot contracts in foreign currencies and cash commodities.
The specific commodity interest contracts will be selected from time to time  by
Rabar  on the bases discussed below. Examples of futures contracts now traded by
Rabar include, but are not necessarily  limited to, gold, silver, U.S.  Treasury
bonds, certain foreign currencies, grains and soybean products, oils, and sugar.
Rabar  may also engage  in EFP transactions.  Under certain circumstances, Rabar
may trade certain futures interest contracts for some clients which it does  not
trade for the Partnership.
 
    Rabar's  trading strategies  have been internally  researched and developed.
They are technical rather than fundamental  in nature, I.E., they are  developed
from the research and analysis of patterns of
 
                                       58
<PAGE>
monthly, weekly, and daily price movements, and of such indicators as volume and
open interest. Rabar does, however, consider the effects of some key fundamental
factors in certain situations, especially for the purpose of controlling risk.
 
    Rabar's risk management techniques include diversification, I.E., commitment
of  equity to  many markets  and to  a number  of trading  strategies. Also, the
trading program at all times adheres  to the requirements of a money  management
system  which determines  and limits  the equity  committed to  each trade, each
market, each commodity complex, and each account. Furthermore, the risk  assumed
and,  consequently, the potential for profit experienced by a particular account
at  different  times,  and  by  different  accounts  at  the  same  time,   vary
significantly  according to market conditions, the  size of a given account, the
percentage gained or lost  in that account, and  the perceived risk aversion  of
that account's owner. Consequently, no investor, including prospective investors
in  the Partnership, should  expect necessarily the same  performance as that of
any other account traded previously, simultaneously, or subsequently by Rabar or
its principal, or of the performance information presented herein.
 
    Rabar's trading program  also emphasizes  current and  ongoing research  and
analysis  of  market behavior  in order  to continue  to develop  strategies for
profiting from the changing character of that behavior. Rabar believes that  the
development  of a commodity trading strategy is a continual process. As a result
of further  analysis  and research  into  the performance  of  Rabar's  methods,
changes  have been made from time to time  in the specific manner in which these
trading methods  evaluate price  movements  in various  commodities, and  it  is
likely  that similar revisions will  be made in the future.  As a result of such
modifications, the trading methods that may be used by Rabar in the future might
differ from those presently being used. The General Partner may not be aware  of
such changes in Rabar's trading methods.
 
    The  markets typically traded by Rabar have been chosen for their historical
performance, and for their customary liquidity. However, from time to time Rabar
may trade  in  newer or  less  liquid markets.  There  can be  no  assurance  of
liquidity.
 
    The  exact nature of  Rabar's methods are  proprietary and confidential. The
foregoing description  is  of  necessity  general and  is  not  intended  to  be
exhaustive.  As stated,  trading decisions require  the exercise  of judgment by
Rabar. The decision  not to  trade certain commodities  or not  to make  certain
trades  may result at  times in missing  price moves and  hence profits of great
magnitude,  which  other  trading  advisors  who  are  willing  to  trade  these
commodities  may be able to capture. There  is no assurance that the performance
of Rabar will result in profitable trading.
 
    Prospective investors should anticipate substantial losses of the portion of
the Partnership's assets  allocated to  Rabar over  long periods  of time  since
profits,  if  any,  are  usually  generated by  only  a  few  trades.  Even more
substantial losses of  profits may occur  because all profits  are subjected  to
ever-increasing  risk by Rabar and because  large portions of unrealized profits
in particular  are  usually  given  back  before  Rabar  determines  that  trend
reversals against its positions have occurred.

    DESCRIPTION OF SUNRISE'S TRADING APPROACH
 
    Sunrise  has historically traded three types of portfolios, all of which are
traded in accordance with the description below.
 
    The first type of portfolio is  a fully diversified futures portfolio  which
follows approximately 15 different markets. Such markets include metals, grains,
petroleum,  soft commodities, interest rates and  currencies. The second type of
portfolio that is available for investment is a currency portfolio which  trades
in  currency  futures  contracts  traded on  the  International  Monetary Market
Division of the Chicago Mercantile Exchange and in forward currency contracts in
the interbank market. The currency portfolio follows approximately 13  different
currencies,  including  the  British  pound,  the  Canadian  dollar,  the German
deutschemark, the Australian  dollar, the  French franc, the  Japanese yen,  the
Swiss  franc,  Spanish  peseta,  Italian lira,  Singapore  dollar  and Malaysian
ringgit. The  third type  of portfolio  available for  investment is  the  CIMCO
portfolio,  which  is derived  from Sunrise's  diversified portfolio.  The CIMCO
portfolio was  designed by  Sunrise to  include selected  financial markets  and
participates  in foreign currency and crossrate trades, interest rates, precious
and industrial metals, and energy products.
 
    Sunrise utilizes technical trend-following systems, trading a wide continuum
of time windows. Most of these time  frames are decidedly long term by  industry
standards.  Pro-active money management strategies  are designed to protect open
profits and  to  minimize  exposure to  non-directional  markets.  In  providing
commodity trading advice to the Partnership, Sunrise trades the CIMCO portfolio.
 
    Relying  on technical analysis, Sunrise believes that future price movements
in all markets may be more accurately anticipated by analyzing historical  price
movements  within a quantitative framework rather  than attempting to predict or
forecast changes in  price through  fundamental economic  analysis. The  trading
methodologies employed by Sunrise are based on programs analyzing a large number
of  interrelated mathematical and statistical  formulas and techniques which are
quantitative, proprietary  in  nature and  which  have been  either  learned  or
developed  by Dr. Davis, and  which have been influenced  by Dr. Forrest and Mr.
Slaughter. The  profitability  of  the  trading  programs,  traded  pursuant  to
technical analysis emphasizing mathematical and charting approaches, will depend
upon  the occurrence  in the  future, as in  the past,  of major  trends in some
markets. If  there  are  no  trends,  the trading  programs  are  likely  to  be
unprofitable.
 
    Sunrise's  trading systems attempt  to detect a  trend, or lack  of a trend,
with respect to a  particular futures interest in  a program by analyzing  price
movement  and  volatility  over  time.  Sunrise's  trading  system  consists  of
multiple, independent and parallel systems, each designed and tested to seek out
and extract different  market inefficiencies on  different time horizons.  These
systems  will generate a signal to sell  a "short" contract or purchase a "long"
contract based upon  their identification  of a  price trend  in the  particular
futures  interest.  If the  systems do  not  detect a  price trend,  a "neutral"
trading
 
                                       61
<PAGE>
signal will be generated.  While this neutral signal  is designed to filter  out
high-risk  "whipsaw"  markets,  it  is  successful  on  only  a  limited  basis.
Successful  speculative  futures  interests  trading  employing  trend-following
techniques,  such  as Sunrise's,  depends  to a  large  degree upon  not trading
non-directional, volatile markets. Accordingly, to  the extent that this  signal
is   not  generated  during  a  non-trading  market,  trading  would  likely  be
unsuccessful because an account would trade such markets.
 
    The number of  losing transactions  may exceed substantially  the number  of
profitable  transactions. However,  if Sunrise's  approach is  successful, these
losses should be more than offset by gains.
 
    While Sunrise relies primarily on its mechanical, technical trading  systems
in making investment decisions, the strategy does include the latitude to depart
from  this  approach if  market  conditions are  such  that, in  the  opinion of
Sunrise, execution  of trades  recommended by  the mechanical  systems would  be
difficult  or  unusually risky.  There  may occur  the  rare instances  in which
Sunrise will override the system  to decrease market exposure. Any  modification
of  trading instructions could adversely affect the profitability of an account.
Among the possible consequences of such a modification would be (1) the entrance
of a trade at a price significantly worse than a system's signal price, (2)  the
complete  negation  of  a  signal  which  subsequently  would  have  produced  a
profitable trade, or (3) the premature termination of an existing trade. Sunrise
is under no obligation  to notify clients (including  Limited Partners) of  this
type  of deviation from its mechanical systems,  since it is an integral part of
its overall trading method.
 
    A technical  trading system  consists of  a series  of fixed  rules  applied
systematically,   however,  the  system  still  requires  Sunrise  make  certain
subjective judgments.  For example,  Sunrise  must select  the markets  it  will
follow  and futures  interests it will  actively trade, along  with the contract
months in  which it  will  maintain positions.  Sunrise must  also  subjectively
determine  when to  liquidate positions  in a contract  month which  is about to
expire and initiate a position in a more distant contract month.
 
    Sunrise  engages  in  ongoing  research   which  may  lead  to   significant
modifications  from time  to time.  Sunrise will  notify the  General Partner if
modifications to its trading systems or portfolio structure are material.
 
    Sunrise believes that the development of  a commodity trading strategy is  a
continual  process.  As  a result  of  further  analysis and  research  into the
performance of Sunrise's methods,  changes have been made  from time to time  in
the  specific manner in which these  trading methods evaluate price movements in
various futures interests, and it is likely that similar revisions will be  made
in  the future. As a result of  such modifications, the trading methods that may
be used by Sunrise in the future might differ from those presently being used.
 
    Sunrise has discretionary authority to make all trading decisions  including
upgrading  or downgrading the trading size of  the account of the Partnership to
reflect additions, withdrawals, trading profits, and/or trading losses,  without
prior  consultation or notice. In addition, Sunrise may from time to time adjust
the leverage  applicable  to  the Partnership's  assets  allocated  to  Sunrise;
provided,  however, any  such adjustments will  be consistent  with the leverage
parameters described herein and the Partnership's overall investment  objectives
and  Trading Policies. Such adjustments may be  in respect of certain markets or
in respect of the overall CIMCO  investment portfolio. Factors which may  affect
the  decision  to  adjust  leverage  include:  ongoing  research,  volatility of
individual markets, risk considerations, and Sunrise's subjective judgement  and
evaluation  of general market conditions. Adjustments  to leverage may result in
greater profits or  losses and increased  brokerage costs. No  assurance can  be
given that any leverage adjustment will be to the financial advantage of Limited
Partners.

commodity  pools for  which the  General Partner  serves as  general partner and
commodity pool operator.
 
   
    DWR is a principal  operating subsidiary of  DWD, a publicly-owned  company.
DWR  is a financial services company that provides to its individual, corporate,
and institutional  clients  services  as  a broker  in  securities  and  futures
interests,  a  dealer in  corporate,  municipal, and  government  securities, an
investment banker,  an investment  adviser, and  an agent  in the  sale of  life

BROKERAGE ARRANGEMENTS
 
    The  Partnership's  brokerage  arrangements  with  DWR,  including  the caps
imposed on certain expenses, are  discussed in "Conflicts of  Interest--Customer
Agreement  with DWR," "Description of Charges to the Partnership--2. Dean Witter
Reynolds Inc." and "--3. Other--(b) Transaction Fees and Costs."
 
    The General Partner will review at least annually the brokerage arrangements
with the  Partnership  to ensure  that  such brokerage  arrangements  are  fair,
reasonable,   and  competitive,  and  represent  the  best  price  and  services
available, taking into consideration, in  particular, when the commodity  broker
is  an "affiliate  " of  the General  Partner (as  such term  is defined  in the
Limited Partnership  Agreement):  (i) the  size  of the  Partnership;  (ii)  the
futures interests trading activity; (iii) the services provided by the commodity
broker,  the General Partner  or any affiliate thereof  to the Partnership; (iv)
the cost  incurred by  the commodity  broker  and the  General Partner  in  this
offering  of Units; (v)  the overall costs  to the Partnership;  (vi) any excess
interest and compensating balance benefits  to the commodity broker from  assets
held  thereby; and  (vii) if  the General  Partner does  not receive  any direct
compensation from the Partnership for its services as General Partner, the risks
incurred by the General Partner as such. See "Conflicts of Interest."
 
    The Customer  Agreement sets  forth  a standard  of  liability for  DWR  and
provides  for certain  indemnities of  DWR as  Commodity Broker.  See "Fiduciary
Responsibility."
 
                                       63
<PAGE>
   
                               CERTAIN LITIGATION
    
 
   
    At  any given time, DWR is involved in numerous legal actions, some of which
seek significant damages. On January 16, 1992, DWR, without admitting or denying
liability, consented to findings in an administrative proceeding brought by  the
SEC  that it  failed to  keep accurate records  with respect  to customer orders
relating to  the  primary distribution  of  securities of  government  sponsored
enterprises  ("GSEs"). In that proceeding, DWR  was censured, paid a civil money
penalty of  $100,000,  and was  ordered  to cease  and  desist from  any  future
violations of Section 17(a) of the 1934 Act and Rules 17a-3 and 17a-4 thereunder
in connection with the primary distribution of securities of GSEs.
    
 
   
    On May 16, 1996, an NASD arbitration panel awarded damages and costs against
DWR  and  one of  its account  executives  in the  amount of  approximately $1.1
million, including punitive damages, to three customers who alleged, among other
things, fraud  and  misrepresentation  in  connection  with  their  individually
managed futures accounts (not commodity pools).
    
 
   
    On September 6, 10, and 20, 1996, similar purported class actions were filed
in  the Superior  Court of the  State of  California, County of  Los Angeles, on
behalf of all  purchasers of  interests in limited  partnership commodity  pools
sold  by DWR. Named defendants include DWR, Demeter Management Corporation, Dean
Witter Futures and Currency  Management Inc., Dean Witter,  Discover & Co.  (all
such   parties  referred  to  hereafter  as  the  "Dean  Witter  Parties"),  the
Partnership, certain other limited partnership commodity pools of which  Demeter
is  the general partner, and  certain trading advisors to  those pools. Also, on
September 18 and  20, 1996  similar purported class  actions were  filed in  the
Supreme Court of the State of New York, New York County, against the Dean Witter
Parties and certain trading advisors on behalf of all purchasers of interests in
various  limited  partnership  commodity  pools sold  by  DWR.  Generally, these
complaints allege,  among other  things, that  the defendants  committed  fraud,
deceit,  misrepresentation,  breach  of fiduciary  duty,  fraudulent  and unfair
business practices, unjust  enrichment, and  conversion in  connection with  the
sale  and  operation of  the various  limited  partnership commodity  pools. The
complaints seek unspecified  amounts of  compensatory and  punitive damages  and
other  relief. It is possible  that additional similar actions  may be filed and
that, in  the  course  of  these  actions,  other  parties  could  be  added  as
defendants.  The Dean Witter Parties believe  that they and the Partnership have
strong defenses to, and they will vigorously contest, the actions. Although  the
ultimate  outcome of legal proceedings cannot be predicted with certainty, it is
the opinion of management of the Dean Witter Parties that the resolution of  the
actions  will not have a  material adverse effect on  the financial condition or
the results of operations of any of the Dean Witter Parties or the Partnership.
    
 
   
    During the five years preceding the date of this Prospectus, there have been
(other than as described  above) no material  criminal, civil or  administrative
actions  pending, on appeal  or concluded against  DWR, Demeter or  any of their
principals which DWR  or Demeter  believes would  be material  to an  investor's
decision to invest in the Partnership.

                           THE MANAGEMENT AGREEMENTS
 
    Each  Trading  Advisor  has entered  into  a Management  Agreement  with the
Partnership and the General Partner which provides that the Trading Advisor  has
sole  authority and  responsibility, except  in certain  limited situations, for
directing the investment and reinvestment of the Partnership's assets in futures
interests.
 
TERM
 
    Each Management Agreement will have a term of two years, commencing from the
date of the  First Closing. Thereafter,  the Trading Advisor  may terminate  the
Management  Agreement, upon 30 days' prior written notice by the Trading Advisor
to the Partnership. In addition, a Trading Advisor may terminate its  Management
Agreement  at any  time without  penalty or  prior written  notice under certain
other circumstances specified therein.
 
    The Management Agreement also will terminate if the Partnership  terminates.
In  addition,  the Management  Agreement may  be  terminated by  the Partnership
without penalty upon  15 days' prior  written notice by  the Partnership to  the
Trading  Advisor or,  without penalty  and without  prior notice,  under certain
other circumstances specified therein.
 
    No assurance  is given  that the  Partnership  will be  able to  retain  the
services  of a new trading advisor if  a Management Agreement is terminated, or,
if such services  are available,  that they  will be  available on  the same  or
similar  terms  as those  of the  prior  Management Agreement.  The compensation
payable by the Partnership  to each Trading Advisor  for its services under  its
Management   Agreement  is  described  under  "Description  of  Charges  to  the
Partnership--1. The Trading Advisors."
 
LIABILITY AND INDEMNIFICATION
 
    Each Management Agreement sets forth a standard of liability for the Trading
Advisor and also provides  for certain indemnities of  the Trading Advisor.  See
"Fiduciary Responsibility".
 
OBLIGATIONS TO THE PARTNERSHIP
 
    The Trading Advisors are engaged in the business of advising investors as to
the  purchase and sale of  futures interests. During the  term of the Management
Agreements, the Trading Advisors, their  principals and affiliates, are free  to
advise  other investors  as to  the purchase and  sale of  futures interests, to
manage and  trade such  investors' futures  interests accounts,  to charge  such
investors  advisory fees at rates  that are different from  the rate charged the
Partnership, and to trade for and  on behalf of their own proprietary  accounts.
However, under no circumstances may any Trading Advisor or any of its principals
and  affiliates by any act  or omission favor (other  than by charging different
management and/or incentive fees) any account advised or managed by the  Trading
Advisor  or its  principals over the  account of  the Partnership in  any way or
manner. Each Trading Advisor will treat the Partnership in a fiduciary  capacity
to  the extent recognized by applicable law,  but, subject to that standard, the
Trading Advisor or any of its principals  and affiliates are free to advise  and
manage  accounts of other  investors and are free  to trade on  the basis of the
same trading systems, methods, or strategies employed by the Trading Advisor  on
behalf  of the  Partnership, or  on the  basis of  trading systems,  methods, or
strategies that are entirely independent of, or materially different from, those
employed on behalf  of the Partnership,  and are  free to compete  for the  same
futures  interests  as the  Partnership, or  to take  positions opposite  to the
Partnership, where such actions  do not knowingly or  deliberately favor any  of
such accounts to the Partnership's account.

                                  REDEMPTIONS
 
    Except  as noted  below, Units may  be redeemed  at the option  of a Limited
Partner (or  any assignee  thereof) as  of, but  not before,  the six-month  end
following  the closing at which such person  first becomes a Limited Partner, in
the manner described herein. Thereafter, Units may be redeemed as of the end  of
any  month. However, any Unit redeemed at the end of the sixth or at or prior to
the twelfth, eighteenth or  twenty-fourth month following  the closing at  which
such  Unit is issued will be assessed a redemption charge equal to 3%, 2% or 1%,
respectively, of the Net Asset Value of  a Unit on the date of such  redemption.
An  investor who purchases $500,000 or more of  Units will not be subject to the
foregoing redemption charges, but will be  subject to the other restrictions  on
redemptions. A limited partner in any of the other commodity pools for which the
General  Partner serves as  the general partner and  commodity pool operator who
redeemed all or a portion of his  interest in one of such other partnerships  on
or  after  December 31,  1995 and  purchases Units  will not  be subject  to the
foregoing redemption charges or  restrictions under the circumstances  described
below.  The number of Units (determined on  a per closing basis), expressed as a
percentage of Units purchased,  which is not subject  to a redemption charge  or
such other restrictions is determined by dividing (a) the dollar amount received
upon  redeeming an interest in such other partnership and used to purchase Units
by (b) the total investment in  the Partnership. For example, a limited  partner
who  receives $5,000 upon redeeming all or a part of his interest in a commodity
pool operated by the General Partner and invests $10,000 in the Partnership will
not be subject to a redemption charge on 50% of his Units. Redemptions of  Units
will  be  deemed  to be  in  the order  in  which they  are  purchased (assuming
purchases at more than one closing), with the Units not subject to a  redemption
charge  or such other restrictions being deemed  to be the first Units purchased
at a closing. The foregoing redemption charges will be paid to DWR.
 
    Redemptions may only be made in whole Units or in multiples of $1,000 (which
may result in  a redemption of  fractional Units), unless  a Limited Partner  is
redeeming  his entire interest in the Partnership. Redemptions will be effective
as of the last day of the month ending after a Request for Redemption in  proper
form  has been  timely received  by the  General Partner  ("Redemption Date"). A
"Request for Redemption" is an irrevocable  letter in the form specified by  the
General Partner and received by the General Partner prior to 5:00 p.m. (New York
time)  at least 5 business days prior to  the Redemption Date. A form of Request
for Redemption is annexed to the Limited Partnership Agreement which is  annexed
hereto  as Exhibit A. Additional forms of Request for Redemption may be obtained
by a written request  to the General  Partner or a local  DWR branch office.  In
addition  to  the information  and reports  described  below under  "The Limited
Partnership Agreement--Reports to  Limited Partners," the  General Partner  will
provide  Limited Partners with  such other information and  will comply with any
such procedures in connection with redemptions as in the future are specifically
required under  Securities  and  Exchange  Commission  rules  and  policies  for
commodity pools and similar investment vehicles.
 
    The  "Net Asset Value"  of a Unit is  the amount of  Net Assets allocated to
capital accounts represented by Units divided by the aggregate number of  Units.
"Net  Assets" are defined in the Limited Partnership Agreement to mean the total
assets of the  Partnership (including,  but not limited  to, all  cash and  cash
equivalents  (valued  at cost),  accrued interest  and amortization  of original
issue discount, and the market value of all open futures interests positions and
other assets  of  the Partnership),  less  all liabilities  of  the  Partnership
(including, but not limited to, one-half of the brokerage commissions that would
be  payable with  respect to  the closing of  each of  the Partnership's futures
interests positions, management fees,  incentive fees, administrative  expenses,
transaction   fees  and  costs,  and   extraordinary  expenses),  determined  in
accordance with generally  accepted accounting  principles consistently  applied
under  the  accrual basis  of accounting.  Unless generally  accepted accounting
principles require otherwise, the market value of a futures interest traded on a
United States exchange or market shall mean the settlement price on the exchange
or market  on which  the particular  futures  interest shall  be traded  by  the
Partnership  on  the  day  with  respect to  which  Net  Assets  are determined,
PROVIDED, HOWEVER, that if a futures interest could not have been liquidated  on
such  day due to the operation of daily limits or other rules of the exchange or
market   upon   which    that   futures    interest   shall    be   traded    or
 
                                       66
<PAGE>
otherwise, the settlement price on the first subsequent day on which the futures
interest  could have been liquidated shall be  the market value of such contract
for such  day. The  market  value of  a futures  interest  traded on  a  foreign
exchange  or market  will mean  its market  value as  determined by  the General
Partner on a basis  consistently applied for each  different variety of  futures
interest.
 
    The  General Partner  shall endeavor to  pay redemptions  within 10 business
days  after  the  Redemption  Date,  and  the  Partnership's  futures  interests
positions  will be  liquidated to  the extent  necessary to  effect redemptions.
Payment is  made by  credit in  the amount  of such  redemption to  the  Limited
Partner's customer account with DWR or by check mailed to the Limited Partner if
such  account is closed. The  right to obtain redemption  is contingent upon (i)
the Partnership having  assets sufficient  to discharge its  liabilities on  the
Redemption Date, and (ii) timely receipt by the General Partner of a Request for
Redemption as described above.
 
    The  terms and conditions  applicable to redemptions  in general, other than
those prohibiting redemptions before the  sixth month-end following the  closing
at  which  a  person  first  becomes  a  Limited  Partner,  and  providing  that
redemptions may only  be made as  of the end  of any calendar  month, will  also
apply  to redemptions effected on "Special Redemption Dates," as described under
"The Limited Partnership Agreement--Reports to Limited Partners."
 
    The liability of  Limited Partners,  including the possible  liability of  a
person  who has redeemed  Units, for liabilities of  the Partnership which arose
before  such   redemption   is   described  under   "The   Limited   Partnership
Agreement--Nature of the Partnership."
 
    Federal  income tax aspects  of redemptions are  described under the caption
"Material Federal Income Tax Considerations."
 
                       THE LIMITED PARTNERSHIP AGREEMENT
 
    This Prospectus contains an  explanation of the  more significant terms  and
provisions  of the Limited  Partnership Agreement of the  Partnership, a copy of
which is  annexed  hereto  as Exhibit  A  and  is incorporated  herein  by  this
reference.
 
NATURE OF THE PARTNERSHIP
 
    The  Partnership was formed on March 21, 1991 under the Partnership Act. The
fiscal year of the Partnership begins on January 1 of each year and ends on  the
following December 31.
 
    Units  purchased and paid for  pursuant to this offering  will be fully paid
and nonassessable.  Except as  described under  "Restrictions on  Transfers  and
Assignments"  below, Limited Partners may only  withdraw from the Partnership by
redeeming all  of their  Units. The  Partnership may  have a  claim against  its
Limited   Partners  after  redemption  or  receipt  of  distributions  from  the
Partnership for liabilities  of the Partnership  that arose before  the date  of
such  redemption or distribution, but such claim will not exceed the sum of such
Limited Partner's  unredeemed capital  contribution, undistributed  profits,  if
any,  and any redemptions or distributions,  together with interest thereon. The
Partnership will not make a claim  against its Limited Partners with respect  to
amounts distributed to them or amounts received by them upon redemption of Units
unless  the  Net Assets  of the  Partnership are  insufficient to  discharge the
liabilities of the Partnership  that arose before the  payment of such  amounts.
The General Partner will be liable for all obligations of the Partnership to the
extent  that assets  of the  Partnership, including  amounts contributed  by its
Limited Partners and  paid out  in distributions, redemptions,  or otherwise  to
Limited  Partners,  are  insufficient to  discharge  such  obligations. However,
neither the  General  Partner,  DWR,  nor  any  of  their  affiliates  shall  be
personally liable to a Limited Partner (or assignee) for the return or repayment
of all or any portion of the capital or profits of such Limited Partner.
 
MANAGEMENT OF PARTNERSHIP AFFAIRS
 
    The  Limited Partners do not participate  in the management or operations of
the Partnership. Any participation by a Limited Partner in the management of the
Partnership may jeopardize the limited
 
                                       67
<PAGE>
liability of  such Limited  Partner. Under  the Limited  Partnership  Agreement,
responsibility  for managing  the Partnership  is vested  solely in  the General
Partner. See  "Fiduciary  Responsibility."  The  General  Partner  may  delegate
complete  trading authority to trading advisors and  has done so (except for the
ability of the General Partner to override trading instructions that violate the
Partnership's trading policies and to the extent necessary to fund distributions
or redemptions,  or to  pay  Partnership expenses)  pursuant to  the  Management
Agreements  with  the  Trading  Advisors. However,  pursuant  to  the Management
Agreements, the General Partner has the  right to make trading decisions at  any
time  at which a  Trading Advisor becomes incapacitated  or some other emergency
arises as a result of which a Trading Advisor is unable or unwilling to act  and
the  General Partner has not yet retained  a successor trading advisor. See "The
Trading Advisors" and "The Management Agreements."
 
    On behalf of the Partnership, the General Partner may engage and  compensate
on  behalf  and from  the  funds of  the  Partnership, such  persons,  firms, or
corporations, including any affiliated person or entity, as the General  Partner
in  its  sole judgment  deems advisable  for  the conduct  and operation  of the
business of the Partnership; PROVIDED, HOWEVER, that, except as described in the
Limited Partnership Agreement and in  this Prospectus, the General Partner  will
not engage on behalf of the Partnership any person, firm, or corporation that is
an  affiliate of  the General  Partner to  perform services  for the Partnership
without having made a good faith determination that: (i) the affiliate which  it
proposes  to engage to perform such services  is qualified to do so (considering
the prior experience of the affiliate or the individuals employed thereby), (ii)
the terms and conditions of the agreement pursuant to which such affiliate is to
perform services for the  Partnership are no less  favorable to the  Partnership
than could be obtained from equally-qualified unaffiliated third parties, or are
otherwise  determined by the  General Partner to  be fair and  reasonable to the
Partnership and the Limited  Partners, and (iii) the  maximum period covered  by
the  agreement pursuant to which  such affiliate is to  perform services for the
Partnership will not  exceed one  year, and  such agreement  will be  terminable
without penalty upon 60 days' prior written notice by the Partnership.
 
    Other  responsibilities of the General Partner  include, but are not limited
to, the following: determining whether the Partnership will make  distributions;
administering  redemptions of Units; preparing monthly and annual reports to the
Limited Partners; directing  the investment of  the Partnership's assets  (other
than investments in futures interests); executing various documents on behalf of
the  Partnership and its Limited  Partners pursuant to a  power of attorney; and
supervising the liquidation of the  Partnership if an event causing  termination
occurs.  To facilitate the execution of various documents by the General Partner
on behalf  of the  Partnership and  its Limited  Partners, each  of the  Limited
Partners  will  appoint the  General Partner,  with  power of  substitution, his
attorney-in-fact by executing a Subscription Agreement and Power of Attorney.
 
ADDITIONAL OFFERINGS
 
    The General  Partner  may, in  its  discretion, make  additional  public  or
private  offerings of Units, provided, that  the net proceeds to the Partnership
of any such sales shall in no event be  less than the Net Asset Value of a  Unit
at  the  time of  sale. The  Partnership shall  not  pay the  costs of  any such
offering or any selling commissions  relating thereto. No Limited Partner  shall
have  any preemptive, preferential or other  rights with respect to the issuance
of any additional  Units, except as  described in the  applicable prospectus  or
other  disclosure document  with respect to  such offering. There  is no maximum
aggregate amount of contributions which may be received by the Partnership.
 
SHARING OF PROFITS AND LOSSES
 
    Each Partner, including the General Partner, of the Partnership will have  a
capital  account with an initial balance equal to the amount paid for Units, or,
in the case of the General Partner, its capital contribution. The  Partnership's
Net Assets will be determined monthly, and any increase or decrease from the end
of  the preceding month will be added to  or subtracted from the accounts of the
Partners in the ratio that each account bears to all accounts.
 
                                       68
<PAGE>
RESTRICTIONS ON TRANSFERS OR ASSIGNMENTS
 
    Except as set forth below,  the Limited Partnership Agreement provides  that
Units may be transferred or assigned, but no transferee or assignee may become a
substituted  Limited Partner without the written consent of the General Partner,
which consent may be withheld in its sole discretion, nor may a Limited Partner,
an assignee  or transferee,  or the  estate  of any  beneficiary of  a  deceased
Limited  Partner withdraw any capital or  profits from the Partnership except by
redemption of Units. See "Redemptions."  The General Partner, without notice  to
or  consent of the Limited Partners, may withdraw any portion of its interest in
the Partnership that  is in excess  of the interest  required under the  Limited
Partnership Agreement.
 
    Any  transfer or  assignment of Units  permitted by  the Limited Partnership
Agreement will be effective as of the end of the month in which such transfer or
assignment is made; PROVIDED, HOWEVER,  that the Partnership need not  recognize
any transfer or assignment until it has received at least 30 days' prior written
notice thereof from the Limited Partner, which notice sets forth the address and
social  security or taxpayer identification number of the transferee or assignee
and the number of Units  transferred or assigned, and  is signed by the  Limited
Partner (a Limited Partner's signature must be guaranteed as provided for in the
Limited  Partnership Agreement).  No transfers or  assignments of  Units will be
effective or recognized by the General Partner if as a result any party to  such
transfer  or assignment owns fewer than the  minimum number of Units required to
be purchased  as described  herein (subject  to certain  exceptions relating  to
gifts, death, divorce, or transfers to family members or affiliates contained in
the  Limited Partnership Agreement). No transfer or assignment will be permitted
unless the General  Partner is satisfied  that (i) such  transfer or  assignment
would  not be in violation of the  Partnership Act or applicable federal, state,
or  foreign  securities  laws,  and   (ii)  notwithstanding  such  transfer   or
assignment,  the Partnership  will continue  to be  classified as  a partnership
rather than  as an  association  taxable as  a  corporation under  the  Internal
Revenue Code. No transfer or assignment of Units will be effective or recognized
by  the  Partnership  if  such  transfer  or  assignment  would  result  in  the
termination of  the  Partnership  for  federal  income  tax  purposes,  and  any
attempted  transfer  or  assignment  in  violation  of  the  Limited Partnership
Agreement will  be ineffective.  The transfer  or assignment  of Units  will  be
subject  to all  applicable securities laws.  The Limited Partner  will bear all
costs (including any attorneys' and accountants' fees) related to such  transfer
or assignment.
 
AMENDMENTS; MEETINGS
 
    The  Limited Partnership Agreement may be amended in accordance with, and to
the extent permissible under, the Partnership Act by an instrument signed by the
General Partner and by Limited Partners owning  more than 50% of the Units  then
outstanding. In addition, the General Partner may make certain amendments to the
Limited  Partnership Agreement without  the consent of  the Limited Partners. No
amendment of the Limited Partnership Agreement  may, without the consent of  all
Partners affected thereby, reduce the capital account of any Partner, modify the
percentage  of  profits,  losses,  or  distributions  to  which  any  Partner is
entitled, or  change or  alter  the provisions  of  such Agreement  relating  to
amendments requiring the consent of all Partners.
 
    Any  Limited  Partner  or his  authorized  attorney or  agent,  upon written
request addressed  to the  General Partner,  delivered either  in person  or  by
certified  mail, and payment of reasonable  duplicating and postage costs, shall
be entitled to obtain from the General Partner  by mail a list of the names  and
addresses  of record of  all Limited Partners  and the number  of Units owned by
each.
 
    Upon receipt of  a written  request, signed  by Limited  Partners owning  at
least  10% of the  Units then owned by  Limited Partners, that  a meeting of the
Partnership be called to  vote upon any matter  upon which all Limited  Partners
may  vote pursuant to the Limited Partnership Agreement, the General Partner, by
written notice  to each  Limited Partner  of record  sent by  certified mail  or
delivered  in person within 15  days after such receipt,  must call a meeting of
the Partnership. Such meeting must be held at least 30 but not more than 60 days
after the mailing  of such  notice, and  such notice  must specify  the date,  a
reasonable time and place, and the purpose of such meeting.
 
                                       69
<PAGE>
    At  any such  meeting, upon  the affirmative  vote (either  in person  or by
proxy) of Limited  Partners owning  more than  50% of  the Units  then owned  by
Limited  Partners, the following actions may be taken without the consent of the
General Partner:  (i)  the  Limited  Partnership Agreement  may  be  amended  in
accordance  with  and  to  the extent  permissible  under  the  Partnership Act;
PROVIDED, HOWEVER, that without the consent of all Partners affected thereby, no
such amendment shall change or alter the provisions of this proviso, reduce  the
capital  account of any Partner, or modify the percentage of profits, losses, or
distributions to which any Partner shall  be entitled; (ii) the Partnership  may
be  dissolved; (iii) the General Partner may be removed and replaced; (iv) a new
general partner or partners may be elected following the withdrawal, insolvency,
bankruptcy, dissolution, liquidation, or termination of the General Partner; (v)
any contracts  with  the  General  Partner  or any  of  its  affiliates  may  be
terminated  without  penalty on  60 days'  prior written  notice to  the General
Partner and such affiliate(s); and (vi) the sale of all or substantially all  of
the  assets of the Partnership may be  approved; PROVIDED, HOWEVER, that no such
action shall  adversely  affect  the  classification of  the  Partnership  as  a
partnership  under United States  federal income tax  laws or the  status of the
Limited Partners as limited partners under the Partnership Act.
 
INDEMNIFICATION
 
    The Limited Partnership  Agreement provides for  certain indemnities of  the
General Partner and its affiliates. See "Fiduciary Responsibility."
 
REPORTS TO LIMITED PARTNERS
 
    The  books and  records of the  Partnership are maintained  at its principal
office. The Limited Partners have the right at all times during normal  business
hours  to have access to and copy such  books and records of the Partnership, in
person or by their  authorized attorney or agent,  and, upon request, copies  of
such  books  and records  will  be sent  to  any Limited  Partner  if reasonable
reproduction and distribution costs  are paid by him.  Within 30 days after  the
close  of each calendar month, the  General Partner shall provide such financial
and other information with respect to the  Partnership as the CFTC and NFA  from
time  to  time  shall  require in  monthly  reports,  together  with information
concerning any material change in the brokerage commissions and fees payable  by
the  Partnership to  DWR. In  addition, if any  of the  following events occurs,
notice of  such  event will  be  mailed to  each  Limited Partner  within  seven
business  days of the occurrence  of the event: (i) a  decrease in the Net Asset
Value of a Unit as of the close of  business on any business day to 50% or  less
of  the Net Asset Value for such Unit as of the end of the immediately preceding
month; (ii) any material amendment  to the Limited Partnership Agreement;  (iii)
any  change  in  trading  advisors  or any  material  change  in  the management
agreement with a trading advisor; (iv) any change in the commodity broker or any
material change in the compensation arrangement with a commodity broker; (v) any
change in  the  general partner  or  any  material change  in  the  compensation
arrangement  with a general partner; (vi) any change in the Partnership's fiscal
year; (vii)  any  material  change  in the  Partnership's  trading  policies  as
specified  in the Limited Partnership Agreement;  or (viii) cessation of futures
interests trading  by  the  Partnership.  In  the case  of  a  notice  given  in
accordance  with  clause (i)  of the  immediately  preceding sentence:  (a) such
notice shall also advise Limited Partners that a "Special Redemption Date," on a
date specified in such notice (but in  no event earlier than 15, nor later  than
45,  days after the mailing of such notice), will take place as of which Limited
Partners  may  redeem  their  Units  in  the  same  manner  as  described  under
"Redemptions"  for regular Redemption Dates (a  Special Redemption Date may take
place on a regular Redemption Date); and (b) following the close of business  on
the  date of the 50% decrease giving  rise to such notice, the Partnership shall
liquidate all existing positions as promptly as reasonably practicable and shall
suspend all  futures  interests trading  through  the Special  Redemption  Date.
Thereafter,  the General Partner shall  determine whether to reinstitute futures
interests trading or  to terminate  the Partnership.  Additionally, the  General
Partner  distributes to the Limited  Partners within 90 days  after the close of
each fiscal  year  an  annual report  containing  audited  financial  statements
(including  a statement of  income and statement of  financial condition) of the
Partnership for  the  fiscal  year  then  ended,  prepared  in  accordance  with
generally  accepted accounting  principles and  accompanied by  a report  of the
certified public accounting  firm which audited  such financial statements,  and
such other
 
                                       70
<PAGE>
information  as the CFTC and the NFA may  from time to time require. Such annual
reports provide  a  detailed statement  of  any transactions  with  the  General
Partner  or its affiliates and of fees, commissions and any compensation paid or
accrued to the General Partner or its affiliates for the fiscal year  completed,
showing the amount paid or accrued to each recipient and the services performed.
Within  75 days after the close of each  fiscal year (but in no event later than
March 15 of each year), the Partnership will report to each Limited Partner  tax
information  necessary  for the  preparation  of the  Limited  Partner's federal
income tax returns.  The Net Asset  Value of  Units is determined  daily by  the
General  Partner  and  the most  recent  Net  Asset Value  calculations  will be
promptly supplied in writing to any  Limited Partner after receipt of a  request
in  writing to such  effect. In addition to  the above-described information and
reports, the  General Partner  will  provide Limited  Partners with  such  other
information  and  will  comply  with  any  such  procedures  in  connection with
redemptions as in the future are specifically required under the Securities  and
Exchange   Commission  rules  and  policies  for  commodity  pools  and  similar
investment vehicles.
 
    In addition,  subject  to  limits imposed  under  certain  state  guidelines
incorporated in the Limited Partnership Agreement, no increase in (a) any of the
management  or incentive fees, or the individual or aggregate caps on such fees,
brokerage commissions,  transaction  fees  and  costs,  ordinary  administrative
expenses,  net  excess interest  and compensating  balance  benefits to  DWR, as
described under "Description  of Charges  to the Partnership,"  may take  effect
until  the first  business day following  a Redemption Date,  PROVIDED that: (1)
notice of such increase is mailed to each Limited Partner at least five business
days prior to the last date on which a "Request for Redemption" must be received
by the General Partner with respect to the applicable Redemption Date; (ii) such
notice describes the redemption and voting rights of Limited Partners; and (iii)
none of  such  fees or  caps  may be  increased  until the  first  business  day
following the first Redemption Date as of which a redemption charge is no longer
payable.
 
                              PLAN OF DISTRIBUTION
 
    The  Units are  being offered  through DWR  pursuant to  a Selling Agreement
among the Partnership and DWR, as selling agent. DWR and the General Partner are
"affiliates" of one another pursuant to SEC rules under the 1933 Act. The  Units
are  being offered  on a "best  efforts" basis  without any agreement  by DWR to
purchase Units. The General  Partner has registered 60,000  Units with the  SEC,
and  the General  Partner, in its  discretion, may register  and sell additional
Units. Also, the Limited Partnership  Agreement provides that additional  public
and/or private offerings may be made at the discretion of the General Partner in
the  future; therefore, there is no maximum  aggregate amount of funds which may
be contributed to the Partnership.
 
   
    Units are  being  offered  for  issuance at  the  First  Closing,  which  is
currently  scheduled to be held on December 2, 1996; PROVIDED, HOWEVER, that the
General Partner may at its discretion hold such First Closing at any time during
the Offering Period (as defined below).  Units that remain unsold following  the
First  Closing may be offered for sale  at a Second Closing, currently scheduled
to be held on  January 2, 1997.  Units that remain  unsold following the  Second
Closing  may be offered for  sale at a Third  Closing, currently scheduled to be
held on February 3, 1997. Units are offered  for sale at a price per Unit  equal
to 100% of the Net Asset Value of a Unit as of the close of business on the last
day  of the month immediately preceding the  date of the applicable closing. The
period from  the date  of this  Prospectus  through February  13, 1997  will  be
referred to herein as the "Offering Period"; PROVIDED, HOWEVER, that the General
Partner  may,  in its  discretion,  extend the  Offering  Period to  provide for
additional closings for the  sale of Units,  but in no  event will the  Offering
Period  be extended beyond March  10, 1997. In the  event of any such extension,
the term "Offering Period" shall be deemed to include such additional closings.
    
 
    Funds with respect to a subscription received during the Offering Period and
not immediately rejected by the General Partner will be promptly transferred to,
and held in escrow by, Chemical Bank,  New York, New York (the "Escrow  Agent"),
as  described below under  "Subscription Procedure," and  invested solely in the
Escrow Agent's interest-bearing money market  account until the General  Partner
 
                                       71
<PAGE>
either rejects such subscription prior to a closing or accepts such subscription
at  a closing. At all times during the  Offering Period, and prior to a closing,
subscription funds will be in the possession of the Escrow Agent and at no  time
will the General Partner handle or take possession of such funds.
 
    Following  each  closing, a  credit will  be  advanced to  each subscriber's
customer account  with  DWR  in  the  amount of  any  interest  earned  on  such
subscriber's  funds  while  held  in escrow.  Interest  earned  on subscriptions
deposited into escrow  and thereafter rejected  by the General  Partner will  be
credited  to  the  subscriber's  customer  account  with  DWR.  In  the  event a
subscriber's customer  account  with  DWR  has  been  closed,  any  subscription
returned  and/or  interest earned  will be  paid by  check. During  the Offering
Period, the General  Partner, DWR,  the Trading Advisors,  and their  respective
principals, directors, officers, employees, and affiliates may subscribe for any
number of Units. Any such subscriptions will be for investment purposes only and
not for resale.
 
    Except  as described below, employees of  DWR will receive from DWR (payable
solely from its own  funds) a gross sales  credit equal to 3%  of the Net  Asset
Value  per Unit  as of  the applicable closing  for each  Unit sold  by them and
issued at such closing.  Employees of DWR who  are properly registered with  the
CFTC  and are members of  the NFA also will  receive, beginning the eighth month
after a Unit was issued, from DWR (payable solely from its own funds) up to  35%
of  the brokerage commissions that are attributable to outstanding Units sold by
them and  received  by  DWR  as  commodity  broker  for  the  Partnership.  Such
compensation  may  only  be paid  to  employees  of DWR  who  are  registered as
associated persons with the CFTC, are members  of the NFA in such capacity,  and
have  passed the Series 3 or Series  31 examination or have been "grandfathered"
as an associated person qualified to do commodity brokerage, and will be paid by
DWR to its employees in consideration of certain additional services relating to
the Units which such employees have agreed  to render on an ongoing basis.  Such
additional  services include: (a) inquiring of  the General Partner from time to
time, at the  request of  Limited Partners,  as to the  Net Asset  Value of  the
Units; (b) inquiring of the General Partner, at the request of Limited Partners,
regarding  the  futures  markets  and the  activities  of  the  Partnership; (c)
responding to questions of Limited Partners with respect to the monthly  account
statements,  annual reports,  financial statements,  and annual  tax information
furnished periodically  to Limited  Partners; (d)  providing advice  to  Limited
Partners  as to when and whether to redeem Units; (e) assisting Limited Partners
in the redemption  of Units; and  (f) providing such  other services as  Limited
Partners  from  time  to  time may  reasonably  request.  The  Selling Agreement
provides that such continuing compensation  may only be paid  by DWR as long  as
such  services  are  provided  and  only to  those  employees  who  are properly
registered with the  CFTC and  are members  of the  NFA. A  Limited Partner  may
telephone, write, or visit such employee at the local DWR branch office to avail
himself of such services.
 
    DWR  will not pay to its employees the 3% gross sales credit described above
with respect  to  Units  purchased  by  a subscriber  with  the  proceeds  of  a
redemption  on  or  after  December  31,  1995  of  all  or  a  portion  of such
subscriber's interest in any other commodity pool for which the General  Partner
serves  as the general partner and  commodity pool operator. Such employees will
receive the gross sales  credit percentage with  respect to roundturn  brokerage
commissions  which are  charged to the  Partnership which are  comparable to the
gross sales credit  which was received  by such employees  with respect to  such
other partnerships.
 
   
    Redemptions  of Units  at or  prior to  the end  of the  twenty-fourth month
following the closing  at which  such Units are  issued are  subject to  certain
redemption  charges payable to DWR. For example, if all 60,000 Units are sold at
the First Closing, the Net Asset Value  per Unit remained at $1,624.40 per  Unit
during  the  first twelve  months following  the First  Closing, all  Units were
subject to a redemption charge,  and all Units were redeemed  at the end of  the
sixth  month  following  the  First Closing,  DWR  would  receive  $2,923,920 in
redemption charges. These redemption  charges may be  deemed to be  underwriting
compensation to DWR. See "Redemptions."
    
 
    In  connection  with the  sale  of Units,  DWR  may implement  a  cash sales
incentive and/or promotional program  for its employees who  sell Units. Such  a
program will provide for DWR, and not the Partnership or General Partner, to pay
its  employees bonus compensation based on sales of Units. Any such program will
be approved by the NASD prior to implementation.
 
                                       72
<PAGE>
    The  aggregate of all commissions paid to  employees of DWR from the initial
3% gross sales  credit, the redemption  charges received by  DWR, and any  sales
incentives will not exceed 10% of the proceeds of the sale of Units.
 
    The  Units are being sold  by the Partnership when,  as and if subscriptions
therefor are accepted  by the General  Partner, subject to  the satisfaction  of
certain  conditions  set forth  in  the Selling  Agreement  and the  approval by
counsel of certain legal  matters. The Partnership has  agreed to indemnify  the
Trading  Advisors in connection with the offer and sale of Units with respect to
any misleading or untrue statement or alleged misleading or untrue statement  of
a  material fact  or a  material omission or  alleged omission  unrelated to the
Trading Advisors or their principals. The Partnership also has agreed to certain
indemnities of  DWR  in  connection  with  the offer  and  sale  of  Units.  See
"Fiduciary Responsibility."
 
                             SUBSCRIPTION PROCEDURE
 
    The minimum subscription for most new subscribers during the Offering Period
is  $5,000, except that the minimum subscription is (a) $2,000 in the case of an
IRA; or  (b) for  subscribers  effecting Exchanges,  the  lesser of  (i)  $5,000
($2,000  in the  case of IRAs),  (ii) the  proceeds from the  redemption of five
units (or two units  in the case  of IRAs) from commodity  pools other than  the
Spectrum  Series, or (iii)  the proceeds from  the redemption of  500 units (200
units in the case of  IRAs) from one of the  Spectrum Series of commodity  pools
(see  "Summary  of the  Prospectus--Investment Requirements").  Existing Limited
Partners who desire  to make  an additional  investment in  the Partnership  may
subscribe for Units at a closing with a minimum investment of $1,000.
 
    In order to purchase Units, a subscriber must complete, execute, and deliver
an execution copy of a Subscription and Exchange Agreement and Power of Attorney
to  DWR. In  the Subscription  and Exchange Agreement  and Power  of Attorney, a
subscriber (other than  one effecting  an Exchange) will  authorize the  General
Partner  and DWR to  transfer the subscription amount  from his customer account
with DWR  to  the  Dean  Witter  Select Futures  Fund  L.P.  Escrow  Account.  A
subscriber  (other  than  one  effecting  an  Exchange)  whose  Subscription and
Exchange  Agreement  and  Power  of  Attorney  is  received  by  DWR  and  whose
subscription  is not immediately  rejected, must have  the appropriate amount in
his customer account with DWR on the first business day following the date  that
his  Subscription and  Exchange Agreement and  Power of Attorney  is received by
DWR, and DWR will debit the customer account and transfer such funds into escrow
with the Escrow Agent on that date.  In the event that a subscriber (other  than
one effecting an Exchange) does not have a customer account with DWR or does not
have  sufficient funds in his existing customer account with DWR, the subscriber
should make appropriate arrangements with his DWR account executive, if any, and
if none, should contact his local DWR branch office. Payment must not be  mailed
to the General Partner, as any mailed payment will be returned to the subscriber
for proper placement with the DWR branch office where his account is maintained.
Additional  investments in the Partnership for subscribers who already own Units
must be made  by executing a  Subscription and Exchange  Agreement and Power  of
Attorney authorizing the immediate transfer of funds from the customer's account
with  DWR to the  Escrow Agent. In the  case of Exchanges,  the execution of the
Subscription and Exchange  Agreement and  Power of Attorney,  a subscriber  will
authorize  the General Partner to  redeem all or a  portion of such subscriber's
interest in  another commodity  pool for  which the  General Partner  serves  as
general  partner  and  commodity pool  operator  (subject  to the  terms  of the
applicable  limited  partnership  agreement)  and  use  the  proceeds  of   such
redemption (less any applicable redemption charges) to purchase Units.
 
    In  the case of a subscription on behalf of an IRA or other employee benefit
plan, merely subscribing for Units does not create a plan. Those considering the
purchase of Units on behalf of an IRA or other employee benefit plan must  first
ensure  that the plan has been properly  established in accordance with the Code
and the regulations thereunder and  administrative rulings thereof and that  the
plan  has been adequately funded.  If an IRA or  other employee benefit plan has
been properly established and adequately funded, the trustee or custodian of the
plan who decides  to or  who is  instructed to do  so may  subscribe for  Units.
Payment   of  the  subscription  price  must  be  made  by  having  the  trustee
 
                                       73
<PAGE>
or custodian of the plan authorize the  General Partner and DWR to transfer  the
subscription  amount to the Dean Witter  Select Futures Fund L.P. Escrow Account
from the plan's customer account with  DWR. An employee benefit plan,  including
an   IRA,  should  consider  the  tax  consequences  of  an  investment  in  the
Partnership. See "Purchase by Employee Benefit Plans--ERISA Considerations."
 
    All Units  subscribed for  upon  DWR's transfer  of  funds from  a  customer
account  following receipt of a check of  a subscriber will be issued subject to
the collection of the funds represented by such check. In the event that a check
of a  subscriber for  Units is  returned  unpaid, DWR  will notify  the  General
Partner,  and the  Partnership will cancel  the Units issued  to such subscriber
represented by such check. Any losses or profits sustained by the Partnership in
connection with the  Partnership's business  allocable to  such cancelled  Units
will  be deemed  a decrease or  increase in  Net Assets and  allocated among the
remaining Partners. In the Limited  Partnership Agreement, each Limited  Partner
agrees  to  reimburse the  Partnership for  any expense  or loss  (including any
trading loss) incurred in connection with  the issuance and cancellation of  any
Units issued to such Limited Partner.
 
    All  subscriptions  for  Units  are  generally  irrevocable  by subscribers,
provided, however,  that  (i)  a  subscriber may  revoke  his  Subscription  and
Exchange  Agreement and  Power of  Attorney, and  receive a  full refund  of the
subscription amount and any accrued  interest thereon (or revoke the  redemption
of  units in the other  commodity pool in the case  of an Exchange), within five
business days after execution of such Agreement or no later than 3:00 P.M.,  New
York City time, on the date of the applicable closing, whichever comes first, by
delivering  written notice to his  DWR account executive; and  (ii) there may be
possible rescission rights under applicable  federal and state securities  laws.
The  General Partner may  reject any subscription,  in whole or  in part, in its
sole discretion. See "Plan of Distribution." A specimen form of the Subscription
and Exchange Agreement and Power of Attorney  is annexed hereto as Exhibit B.  A
separate  execution copy of the Subscription and Exchange Agreement and Power of
Attorney accompanies this Prospectus or may be obtained, after delivery of  this
Prospectus,  from a local  DWR branch office. Limited  Partners will not receive
certificates evidencing Units,  but will  be sent confirmations  of purchase  in
DWR's customary form.
 
                     PURCHASES BY EMPLOYEE BENEFIT PLANS--
                              ERISA CONSIDERATIONS
 
    The  purchase of Units  might or might  not be a  suitable investment for an
employee benefit plan. Before proceeding with  such a purchase, the person  with
investment  discretion  on behalf  of an  employee  benefit plan  must determine
whether the purchase of Units is  (a) permitted under the governing  instruments
of  the plan and (b) appropriate for that particular plan in view of its overall
investment policy, the composition and diversification of its portfolio, and the
considerations discussed below.
 
    As used  herein, the  term  "employee benefit  plans"  refers to  plans  and
accounts of various types (including their related trusts) which provide for the
accumulation  of a portion of an  individual's earnings or compensation, as well
as investment income  earned thereon, free  from federal income  tax until  such
time  as  funds are  distributed  from the  plan.  Such plans  include corporate
pension and profit-sharing plans (such  as so-called 401(k) plans),  "simplified
employee  pension plans," so-called "Keogh"  plans for self-employed individuals
(including  partners),  and,  for   purposes  of  this  discussion,   individual
retirement  accounts ("IRAs"), described in Section  408 of the Internal Revenue
Code of 1986, as amended (the "Code").
 
    Notwithstanding  the  general  requirement   that  most  investors  in   the
Partnership  must invest a minimum of  $5,000, a minimum purchase requirement of
$2,000 has been  set for  IRAs. See "Investment  Requirements." Greater  minimum
purchases  and special suitability  standards may be  mandated by the securities
laws and regulations of  certain states, and each  plan investor should  consult
the  Subscription and Exchange Agreement and  Power of Attorney to determine the
applicable investment requirements. See "Subscription Procedure."
 
                                       74
<PAGE>
    If the assets of an investing employee benefit plan were to be treated,  for
purposes  of the  reporting and disclosure  provisions and certain  other of the
fiduciary responsibility provisions of Title I of the Employee Retirement Income
Security Act of 1974,  as amended ("ERISA"),  and Section 4975  of the Code,  as
including  an  undivided  interest  in  each of  the  underlying  assets  of the
Partnership, an  investment  in  Units  would in  general  be  an  inappropriate
investment   for  the  plan.   A  U.S.  Department   of  Labor  regulation  (the
"Regulation") defines "plan assets" in  situations where employee benefit  plans
purchase  equity securities in investment entities  such as the Partnership. The
Regulation provides that the assets of an entity will NOT be deemed to be  "plan
assets"  of an employee benefit plan which  purchases an equity security of such
an entity if the equity security is a "publicly-offered security," meaning it is
(1) freely transferable, (2) held by more than 100 investors independent of  the
issuer  and of each other, and (3)  either (i) registered under Section 12(b) or
Section 12(g) of  the Securities  Exchange Act of  1934, as  amended (the  "1934
Act")  or (ii) sold to the plan as  part of a public offering of such securities
pursuant to an effective  registration statement under the  1933 Act, where  the
security  is then timely registered under Section  12(b) or Section 12(g) of the
1934 Act.  It  is  expected  that  the Units  will  meet  the  criteria  of  the
Regulation.
 
    The  General Partner believes,  based upon the advice  of its legal counsel,
that income earned by  the Partnership will  not constitute "unrelated  business
taxable  income" under  Section 512  of the Code  to employee  benefit plans and
other tax-exempt entities  which purchase Units.  Although the Internal  Revenue
Service  has issued  favorable private letter  rulings to  taxpayers in somewhat
similar circumstances,  other taxpayers  may not  use or  cite such  rulings  as
precedent.  Persons  with investment  discretion on  behalf of  employee benefit
plans who are considering  the purchase of Units  should consult a  professional
tax adviser regarding the application of the foregoing matters to their purchase
of Units.
 
    Units  may not be purchased  with the assets of  an employee benefit plan if
the General Partner,  DWR, or  any Trading Advisor  or any  of their  respective
affiliates  either: (a) has investment discretion with respect to the investment
of such plan assets;  (b) has authority or  responsibility to give or  regularly
gives  investment advice with respect to such plan assets for a fee and pursuant
to an agreement or understanding that such advice will serve as a primary  basis
for  investment decisions with respect to such  plan assets and that such advice
will be based  on the  particular investment  needs of the  plan; or  (c) is  an
employer maintaining or contributing to such plan.
 
    Subscribing for Units does not create an IRA or other employee benefit plan.
Those  considering the purchase of  Units on behalf of  an IRA or other employee
benefit plan must first  ensure that the plan  has been properly established  in
accordance  with  the Code  and  the regulations  thereunder  and administrative
rulings thereunder and that the plan has been adequately funded. Then, after all
of the considerations discussed above have been taken into account, the  trustee
or  custodian  of a  plan who  decides  to or  who is  instructed  to do  so may
subscribe for Units, subject to the minimum subscription requirement.
 
    ACCEPTANCE OF SUBSCRIPTIONS  ON BEHALF OF  EMPLOYEE BENEFIT PLANS  IS IN  NO
RESPECT  A REPRESENTATION BY  THE GENERAL PARTNER, DWR,  THE TRADING ADVISORS OR
THE PARTNERSHIP THAT THIS INVESTMENT MEETS ALL RELEVANT LEGAL REQUIREMENTS  WITH
RESPECT  TO INVESTMENTS BY PLANS  GENERALLY OR ANY PARTICULAR  PLAN OR THAT THIS
INVESTMENT IS APPROPRIATE FOR PLANS GENERALLY OR ANY PARTICULAR PLAN.

                   MATERIAL FEDERAL INCOME TAX CONSIDERATIONS
 
INTRODUCTION
 
    The General Partner has  been advised by  counsel, Cadwalader, Wickersham  &
Taft,  that  in  its  opinion, the  following  summary  correctly  describes the
material  federal  income  tax  consequences  to  United  States  taxpayers   of
acquiring,  owning,  and  disposing of  Units.  The opinions  appearing  in this
section are the opinions of Cadwalader,  Wickersham & Taft, except as  otherwise
specifically  noted herein.  The following  summary is  based upon  the Internal
Revenue Code  of 1986,  as amended  (the "Code"),  rulings thereon,  regulations
promulgated  thereunder and existing interpretations thereof, any of which could
be changed  at any  time and  which changes  could be  retroactive. The  federal
income  tax summary and the  state and local income  tax summary which follow in
general relate only to the tax implications of an investment in the  Partnership
by  individuals who are  citizens or residents  of the United  States. Except as
indicated  below   or  under   "Purchases  by   Employee  Benefit   Plans--ERISA
Considerations,"  the  summaries  do  not address  the  tax  implications  of an
investment in the Partnership by  corporations, partnerships, trusts, and  other
non-individuals.  Moreover, the summaries  are not intended  as a substitute for
careful tax  planning, particularly  since certain  of the  tax consequences  of
owning  an interest in  the Partnership may  not be the  same for all taxpayers,
such as  non-individuals  or foreign  persons,  or  in light  of  an  investor's
personal  investment circumstances. A complete  discussion of all federal, state
and local tax aspects of an investment in the Partnership is beyond the scope of
the following  summary, and  prospective investors  must consult  their own  tax
advisors on such matters.
 
PARTNERSHIP STATUS
 
    The  General  Partner has  been advised  by  its legal  counsel, Cadwalader,
Wickersham & Taft, that in its opinion under current federal income tax law, the
Partnership will  be classified  as  a partnership  and  not as  an  association
taxable as a corporation. No ruling has been requested from the Internal Revenue
Service  with  respect  to classification  of  the Partnership  and  the General
Partner does not intend to request such a ruling.
 
    The opinion of  counsel described above  is based upon  the facts set  forth
herein,  including  that  (i) the  General  Partner  will maintain  a  net worth
(exclusive of its interest in the Partnership and any other limited partnership)
equal to the sum of at least  10% of the total contributions to the  Partnership
and  any other limited partnership for which  it acts as general partner (or, if
the total contributions to the Partnership  or to any other limited  partnership
are  less  than  $2,500,000, of  at  least  15% of  total  contributions  to the
Partnership and  to any  other  limited partnership  or $250,000,  whichever  is
lesser);  (ii) the General Partner's interest  in each item of the Partnership's
income, gain, loss, deduction, or  credit will be equal to  at least 1% of  each
such  item; (iii)  the Limited  Partners will  not own,  directly or indirectly,
individually or in  the aggregate, more  than 20%  of the stock  of the  General
Partner  or  of any  affiliate  of the  General  Partner; and  (iv)  a principal
activity of the Partnership consists of buying and selling commodities not  held
as  inventory, or  futures, options and  forward contracts with  respect to such
commodities, and at least 90% of the Partnership's income consists of gains from
such trading and interest income.
 
    Certain "publicly traded partnerships" are taxed as corporations. While this
treatment does  not  affect  the  Partnership,  new  legislation  governing  the
taxation  of limited partnerships may  be enacted at any  time, and may apply to
the  Partnership  retroactively.  If  a   partnership  were  classified  as   an
association  taxable as a corporation, income  or loss of such partnership would
not be passed through to its partners, and such partnership would be subject  to
tax  on its income without  deduction for any distributions  to its partners, at
the rates  applicable to  corporations. In  addition, all  or a  portion of  any
distributions  by  such partnership  to  its partners  could  be taxable  to the
partners as dividends or capital gains.
 
PARTNERSHIP TAXATION
 
    PARTNERS, RATHER  THAN PARTNERSHIP,  SUBJECT  TO FEDERAL  INCOME TAX.    The
Partnership,  as an entity, will not be subject to federal income tax. Except as
provided below with respect to certain nonresident
 
                                       76
<PAGE>
aliens, each Limited Partner in computing his federal income tax liability for a
taxable year will be required to take into account his distributive share of all
items of Partnership income, gain, loss,  deduction, and credit for the  taxable
year  of the Partnership ending within or with the taxable year of such Partner,
regardless of  whether such  Partner  has received  any distributions  from  the
Partnership.  The characterization of an item of  profit or loss will usually be
determined at the Partnership level.
 
    ORGANIZATION AND  SYNDICATION EXPENSES.   Neither  the Partnership  nor  any
Partner  thereof  will be  entitled to  any  deduction for  syndication expenses
(I.E., those amounts paid or incurred  in connection with issuing and  marketing
Units).
 
    ALLOCATION  OF  PARTNERSHIP  PROFITS AND  LOSSES.   For  federal  income tax
purposes, a Limited Partner's distributive share of items of Partnership income,
gain, loss, deduction, and credit will be determined by the Limited  Partnership
Agreement,  annexed  hereto  as  Exhibit  A,  unless  an  allocation  under such
Agreement does not have  "substantial economic effect" or  is not in  accordance
with the Partners' interests in the Partnership. The allocations provided by the
Limited  Partnership  Agreement  are described  under  "The  Limited Partnership
Agreements--Allocation  of  Profits  and   Losses."  In  general,  the   Limited
Partnership  Agreement allocates items  of ordinary income  and expense pro rata
among the Partners based upon their respective capital accounts as of the end of
the month in which such items are accrued. Net realized capital gains and losses
are generally allocated among all  Partners based upon their respective  capital
accounts.  However, net  realized capital  gain and  loss is  allocated first to
Partners who have redeemed Units in the Partnership during a taxable year to the
extent of the difference between the  amount received on the redemption and  the
allocation  account as  of the date  of redemption attributable  to the redeemed
Units. Net realized  capital gains for  each year are  allocated next among  all
Partners  whose  capital  accounts  are in  excess  of  their  Units' allocation
accounts to the  extent of such  excess in  the ratio that  each such  Partner's
excess  bears to all such Partners' excesses. Net realized capital loss for each
year is allocated next among all  Partners whose Units' allocation accounts  are
in  excess of their capital  accounts to the extent of  such excess in the ratio
that each such Partner's excess bears to all such Partners' excesses.
 
    These allocation provisions  are designed  to reconcile  tax allocations  to
economic  allocations.  However, no  assurance can  be  given that  the Internal
Revenue Service  will not  challenge such  allocations, especially  in light  of
recently issued final regulations.
 
    If  the  allocation provided  by the  Limited  Partnership Agreement  is not
recognized by the Internal Revenue Service for federal income tax purposes,  the
amount  of  income or  loss allocated  to  the Partners  for federal  income tax
purposes under the Limited Partnership Agreement may be increased or reduced  or
the character of such income or loss may be modified.
 
CASH DISTRIBUTIONS AND REDEMPTIONS
 
    Distributions  by the Partnership  and amounts received  upon the partial or
complete redemption of a Limited Partner's Units will be taxable to the  Limited
Partner  to the extent cash distributions by the Partnership or amounts received
upon redemption by a Limited Partner exceed such Partner's adjusted tax basis in
his Units. Such excess will be  taxable to him as though  it were a gain from  a
sale of the Units. A loss will be recognized upon a redemption of Units only if,
following  the redemption of all of a  Limited Partner's Units, such Partner has
any tax basis in  his Units remaining.  In such case,  the Limited Partner  will
recognize  loss  to  the  extent of  such  remaining  basis.  See "Redemptions."
Generally, if a Limited Partner is not  a "dealer" with respect to his  interest
in the Partnership and he has held his interest in the Partnership for more than
one year, such gain or loss would be long-term capital gain or loss.
 
GAIN OR LOSS ON TRADING ACTIVITY
 
    Because  the Partnership will  purchase futures interests  contracts for its
own account and not for the account of others, because the Partnership will  not
maintain  an inventory of futures interests contracts, because substantially all
of the  expected  return  of  any combination  of  the  Partnership's  commodity
contract   positions  will  not  be  attributable  to  the  time  value  of  the
Partnership's net
 
                                       77
<PAGE>
investment in such positions, and because  the Partnership will be considered  a
"qualified  fund"  for  purposes  of its  foreign  currency  commodity contracts
positions, for federal income tax purposes  substantially all of the profit  and
loss  generated by the  Partnership from its trading  activities will be capital
gain and  loss,  which  in  turn  may  be  either  short-term,  long-term  or  a
combination  of both. Gain or loss with  respect to a "Section 1256 contract" is
generally treated as short-term  capital gain or  loss to the  extent of 40%  of
such  gain or loss, and long-term  capital gain or loss to  the extent of 60% of
such gain or loss. For individual partners, long-term capital gains are taxed at
a maximum marginal  rate of 28%,  while short-term capital  gains are  currently
taxed at a maximum marginal rate of 39.6%. For corporate partners, long-term and
short-term capital gains are taxed at the same rate.
 
    A  "Section  1256  contract"  includes  a  "regulated  futures  contract," a
"foreign currency contract," a "nonequity option," and a "dealer equity option."
A "regulated  futures contract"  is a  futures contract  which is  traded on  or
subject  to the rules of a national securities exchange which is registered with
the SEC, a domestic board of trade designated as a contract market by the  CFTC,
or  any  other  board of  trade,  exchange  or other  market  designated  by the
Secretary of  the Treasury  ("a  qualified board  or  exchange"), and  which  is
"marked-to-market"  to determine the amount of margin which must be deposited or
may be withdrawn.  A "foreign currency  contract" is a  contract which  requires
delivery  of, or the  settlement of which  depends upon the  value of, a foreign
currency which  is  a  currency  in which  positions  are  also  traded  through
regulated  futures contracts, which is traded in the interbank market, and which
is entered into at arm's length at a price determined by reference to the  price
in  the interbank market. (The Secretary of  the Treasury is authorized to issue
regulations excluding  certain currency  forward contracts  from  mark-to-market
treatment.)  A "nonequity option" means an option which is traded on a qualified
board or  exchange  and  the  value  of which  is  not  determined  directly  or
indirectly by reference to any stock (or group of stocks) or stock index, unless
(i)  there is in  effect a designation  by the CFTC  of a contract  market for a
contract based on such group of stocks or  stock index or (ii) such option is  a
cash-settled  option  on  a  stock  index that  the  SEC  has  determined  to be
"broad-based." A  "dealer  equity option"  means,  with respect  to  an  options
dealer,  any listed option which is an equity option, is purchased or granted by
such options dealer in the normal course of his activity of dealing in  options,
and is listed on the qualified board or exchange on which such options dealer is
registered.  Each Section  1256 contract  held at  the end  of the Partnership's
taxable year will be treated  as having been sold for  its fair market value  on
the  last day of such taxable year, and  gain or loss will be taken into account
for such year. The Partnership expects that a portion of its trading  activities
will  be  conducted in  Section 1256  contracts;  however, the  Partnership also
expects that a portion of its trading activities will be conducted in  contracts
that  do  not presently  qualify as  Section  1256 contracts  ("non-Section 1256
contracts").
 
    Gain or loss with respect to foreign currency forward and futures  contracts
that are not traded on U.S. exchanges or on certain foreign exchanges designated
as  "qualified boards  or exchanges" by  the Internal  Revenue Service ("foreign
currency positions") is  treated as  capital gain  or loss  only if  held by  an
electing  "qualified  fund."  In  general, a  "qualified  fund"  is  an electing
partnership that: (1) has at least 20  unrelated partners (no one of which  owns
more  than 20%  of the  capital or  profits of  the partnership);  (2) has  as a
principal activity the buying and selling of options, futures, or forwards  with
respect  to commodities; and (3) receives at  least 90% of its gross income from
interest, dividends, gain from  the sale or disposition  of capital assets  held
for  the production of interest or dividends,  and income and gain from futures,
forward, and  option contracts  with respect  to commodities.  All such  foreign
currency  positions  held  by a  qualified  fund  are treated  as  "Section 1256
contracts" (I.E., marked-to-market at year end) and gain or loss with respect to
such foreign currency positions is treated as 100% short-term gain or loss. Gain
or loss  with  respect  to  "regulated  futures  contracts,"  "foreign  currency
contracts" and "nonequity options" is generally treated as 60% long-term gain or
loss  and 40% short-term gain or loss.  The General Partner has made a qualified
fund election for the Partnership.
 
    Subject to certain limitations, a Limited Partner, other than a corporation,
estate, or trust, may elect  to carry back net  Section 1256 contract losses  to
each of the three preceding years. Net Section 1256
 
                                       78
<PAGE>
contract  losses carried  back to  prior years  may only  be used  to offset net
Section 1256 contract  gains. Generally,  such losses  are carried  back as  40%
short-term  capital losses and 60% long-term  capital losses. Capital assets not
marked to the market under Section 1256, such as non-currency forward contracts,
are not subject to the 60/40 tax regime for Section 1256 contracts, and gain  or
loss on sale generally will be long-term only if such property has been held for
more than one year.
 
    During  taxable years in which little or no profit is generated from trading
activities, a Limited Partner may still have interest income.
 
    The Partnership may  engage in  spread and straddle  trading (I.E.,  holding
offsetting  positions  whereby the  risk  of loss  from  holding either  or both
position(s) is substantially  diminished). Realized losses  with respect to  any
position  in a spread or straddle are  taken into account for federal income tax
purposes only to the extent that the losses exceed unrecognized gain (at the end
of  the  taxable  year)  from  offsetting  positions,  successor  positions,  or
offsetting positions to the successor positions. Thus, spreads and straddles may
not  be used to  defer gain from one  taxable year to the  next. For purposes of
applying the above rules restricting the deductibility of losses with respect to
offsetting positions, if a Partner takes into account gain or loss with  respect
to  a position held by  the Partnership, the Partner  will be treated as holding
the  Partnership's  position,  except  to  the  extent  otherwise  provided   in
regulations.  Accordingly,  positions  held  by the  Partnership  may  limit the
deductibility of realized losses sustained by a Limited Partner with respect  to
positions  held for his own account, and positions held by a Limited Partner for
his own account may limit his ability to deduct realized losses sustained by the
Partnership. Reporting requirements generally require taxpayers to disclose  all
unrecognized  gains with  respect to  positions held at  the end  of the taxable
year. The above principle, whereby a  Limited Partner may be treated as  holding
Partnership positions, may also apply to require a Limited Partner to capitalize
(rather than deduct) interest and carrying charges allocable to property held by
him.  A portion of the gain on  a "conversion transaction," including spread and
straddle trading, may  be characterized as  ordinary income where  substantially
all  of  the  expected return  is  attributable to  the  time value  of  the net
investment in the transaction.
 
    Pursuant to current Proposed and Temporary Treasury Regulations, the holding
period of any position included in a  straddle begins anew when the straddle  is
terminated unless the position was held for more than the long-term capital gain
and  loss holding period before the  straddle was established. Further, the loss
on any position included in  a straddle will be  treated as a long-term  capital
loss  if,  at  the  time  the loss  position  was  acquired,  the  taxpayer held
offsetting positions with  respect to such  loss position that  would give  rise
only  to long-term capital loss if such offsetting positions were disposed of on
the day the loss position was acquired.
 
    Where the positions  of a straddle  are comprised of  both Section 1256  and
non-Section  1256  contracts,  the  Partnership will  be  subject  to  the mixed
straddle rules  of the  Code  and the  regulations promulgated  thereunder.  The
appropriate  tax  treatment  of  any  gains and  losses  from  trading  in mixed
straddles  will  depend  on  which  of  the  following  four  alternatives   the
Partnership  elects to pursue.  The Partnership may elect  to treat Section 1256
positions as non-Section 1256 positions, and the mixed straddle would be subject
to  the  rules   governing  non-Section  1256   straddles.  Alternatively,   the
Partnership   may  identify  the  positions  of  a  particular  straddle  as  an
"identified mixed straddle" under Section  1092(b)(2) of the Code and,  thereby,
net  the capital gain or loss attributable  to the offsetting positions. The net
capital gain or loss is treated as 60% long-term and 40% short-term capital gain
or loss if attributable to the Section 1256 positions, or all short-term capital
gain or loss if attributable  to the non-Section 1256 positions.  Alternatively,
the  Partnership may place the positions in  a "mixed straddle" account which is
marked-to-market daily. Under a  special account cap, not  more than 50% of  net
capital gain may be long-term capital gain, and not more than 40% of net capital
loss may be short-term capital loss. If the Partnership does not make any of the
aforementioned  three elections, any net loss attributable to either the Section
1256 or the non-Section 1256 positions will be treated as 60% long-term and  40%
short-term capital loss, while any net gain will be treated as 60% long-term and
40%  short-term capital  gain, or  all short-term  capital gain,  depending upon
whether the net gain was attributable  to Section 1256 positions or  non-Section
1256 positions.

TAXATION OF LIMITED PARTNERS
 
    LIMITATIONS   ON  DEDUCTIBILITY  OF  PARTNERSHIP  LOSSES.    The  amount  of
Partnership loss,  including  capital loss,  which  a Limited  Partner  will  be
entitled  to take into account for federal income tax purposes is limited to the
lesser of  the tax  basis  of his  Units  or (in  the  case of  certain  Limited
Partners, including individuals and closely-held C corporations) the amounts for
which  he  is "at  risk" with  respect to  such interest  as of  the end  of the
Partnership's taxable year in which such loss occurred.
 
    Generally, a Limited Partner's initial tax basis will be the amount paid for
each Unit of the Partnership (100%  of the Net Asset Value  of a Unit as of  the
close  of  business of  the  last day  of  the month  immediately  preceding the
applicable closing for Units sold at such closing). A Limited Partner's adjusted
tax basis will be his initial tax  basis reduced by the Limited Partner's  share
of  Partnership distributions, losses and expenses and increased by his share of
Partnership income, including gains. The amount  for which a Limited Partner  is
"at  risk" with  respect to  his interest in  the Partnership  will generally be
equal to his  tax basis for  such interest,  less: (i) any  amounts borrowed  in
connection  with his acquisition of such interest for which he is not personally
liable and for which he  has pledged no property  other than his interest;  (ii)
any  amounts  borrowed  from persons  who  have  a proprietary  interest  in the
Partnership; and (iii)  any amounts borrowed  for which the  Limited Partner  is
protected against loss through guarantees or similar arrangements.
 
    Because  of the limitations imposed upon the deductibility of capital losses
referred to below, a  Limited Partner's share of  the Partnership's net  capital
losses,  if  any, will  not  materially reduce  his  federal income  tax  on his
ordinary income.  In addition,  certain  expenses of  the Partnership  might  be
deductible  by a Partner  only as so-called  itemized deductions and, therefore,
will not reduce the federal taxable income of a Partner who does not itemize his
deductions. Furthermore, an individual who is subject to the alternative minimum
tax for a  taxable year  will not  realize any  tax benefit  from such  itemized
deductions.
 
    LIMITATIONS  ON DEDUCTIBILITY OF PASSIVE LOSSES.   In general, losses from a
passive activity ("passive  losses") are  disallowed to the  extent such  losses
exceed income from all passive activities ("passive income"). A passive activity
is  defined as  a trade or  business in  which the taxpayer  does not materially
participate unless otherwise provided in Treasury Regulations.
 
    Proposed and  Temporary Treasury  Regulations provide  that the  trading  of
personal  property,  such  as commodities,  will  not  be treated  as  a passive
activity. Accordingly,  a  Limited  Partner's distributive  share  of  items  of
income,  gain, deduction, or  loss from the  Partnership will not  be treated as
passive income or loss and Partnership gains allocable to Limited Partners  will
not  be available to offset passive losses from sources outside the Partnership.
Partnership gains allocable to Limited  Partners will, however, be available  to
offset losses with respect to "portfolio" investments, such as stocks and bonds.
Moreover, any Partnership losses allocable to Limited Partners will be available
to  offset other  income, regardless of  source. Final  Treasury Regulations may
modify the  Proposed and  Temporary  Regulations, and  such regulations  may  be
retroactive in effect.
 
    LIMITED  DEDUCTION  OF  CERTAIN EXPENSES.    Certain  miscellaneous itemized
deductions, such as expenses incurred to maintain property held for  investment,
are  deductible only  to the extent  that they  exceed 2% of  the adjusted gross
income of  an individual,  trust,  or estate.  The  amount of  certain  itemized
deductions allowable to individuals is further reduced by an amount equal to the
lesser  of  (i) 3%  of the  individual's adjusted  gross income  in excess  of a
certain threshold  amount (for  tax  years beginning  in  1995, this  amount  is
$114,700  ($57,350 in the case of married individuals filing a separate return))
and (ii) 80% of such itemized deductions. Based upon the contemplated activities
of the Partnership, the  General Partner has been  advised by its legal  counsel
that,  in such  counsel's opinion, expenses  incurred by the  Partnership in its
futures interests trading business  should not be subject  to the 2% "floor"  or
the  3%  phaseout,  except  to  the extent  that  the  Internal  Revenue Service
promulgates regulations that so provide.
 
                                       80
<PAGE>
    TAX ON CAPITAL GAINS AND LOSSES.  For individuals, trusts and estates,  "net
capital  gains" are currently taxed at a maximum marginal tax rate of 28%, while
other income  is  taxed at  a  maximum marginal  tax  rate of  39.6%.  Corporate
taxpayers  are currently subject  to a maximum  marginal tax rate  of 35% on all
income.
 
    The excess  of  capital  losses  over capital  gains  is  deductible  by  an
individual  against ordinary income on a one-for-one basis, subject to an annual
limitation of  $3,000  ($1,500 in  the  case  of married  individuals  filing  a
separate return). Excess capital losses may be carried forward.
 
    Net  losses from Section 1256 contracts are treated as 60% long-term capital
loss and  40%  short-term capital  loss.  Such  losses may,  at  the  individual
taxpayer's  election, be carried back  to each of the  preceding three years and
applied against gains from Section 1256 contracts.
 
    ALTERNATIVE MINIMUM  TAX.   An alternative  minimum tax  may be  imposed  on
Limited  Partners, depending on  their particular circumstances.  This tax, with
respect to taxpayers  other than corporations,  will be assessed  to the  extent
that  26%  of  the first  $175,000  ($87,500  for married  individuals  filing a
separate return)  of  "alternative minimum  taxable  income" in  excess  of  the
exemption  amount ($45,000 in the case of married taxpayers filing joint returns
or a surviving spouse; $33,750 in the case of an unmarried taxpayer who is not a
surviving spouse;  or $22,500  in the  case  of a  married individual  filing  a
separate  return or an estate  or trust) plus 28% of  the balance of such excess
exceeds the taxpayer's regular federal income tax liability (subject to  special
modification)  for the year. The alternative minimum tax exemption is phased-out
for individual taxpayers with  alternative minimum taxable  income in excess  of
$112,500  ($150,000 for  married taxpayers filing  a joint  return and surviving
spouses; $75,000 for married individuals  filing separate returns, estates,  and
trusts).  "Alternative minimum taxable income" is equal to adjusted gross income
computed without  deducting  normal net  operating  losses, less  specified  net
operating  losses,  credits, trust  distributions  and itemized  deductions, and
increased by certain  tax preferences. Long-term  capital gains are  taxed at  a
maximum  28% rate. However,  the limitation on the  long-term capital gains rate
does not give rise to an adjustment or increase in "alternative minimum  taxable
income."  Therefore, transactions in Section  1256 contracts should not directly
affect the application of  the alternative minimum tax.  The extent, if any,  to
which the alternative minimum tax will be imposed will depend on the overall tax
situation of each Limited Partner at the end of each such taxable year.
 
    LIMITATION ON DEDUCTIBILITY OF INTEREST ON INVESTMENT
INDEBTEDNESS.   Interest paid  or accrued on  indebtedness properly allocable to
property held for investment is investment interest. Such interest is  generally
deductible  by non-corporate taxpayers only to the extent it does not exceed net
investment income. A  Limited Partner's  distributive share  of net  Partnership
income  and any gain from the disposition of Units will be treated as investment
income, except that a Limited Partner's net capital gain from the disposition of
Units is not investment income unless the Limited Partner waives the benefit  of
the  28% tax  rate on  such gain. It  is not  clear whether  a Limited Partner's
distributive share of Partnership net capital gain constitutes investment income
where such gain is taxed at the maximum 28% rate. Interest expense incurred by a
Limited Partner to acquire his Units generally will be investment interest.  Any
investment interest disallowed as a deduction in a taxable year solely by reason
of the limitation above is treated as investment interest paid or accrued in the
succeeding taxable year.
 
    TAXATION  OF  FOREIGN  LIMITED  PARTNERS.    A  Limited  Partner  who  is  a
non-resident alien individual, foreign corporation, foreign partnership, foreign
trust, or foreign estate (a "Foreign Limited Partner") generally is not  subject
to  taxation by  the United  States on United  States source  capital gains from
commodity trading for a taxable year, provided that such Foreign Limited Partner
does not  have certain  present or  former connections  with the  United  States
(e.g.,  if the Foreign Limited  Partner (in the case  of an individual) does not
spend more than 182 days  in the United States during  his taxable year (or,  in
certain  limited circumstances, a prior taxable year), or if the Foreign Limited
Partner is not engaged in a
 
                                       81
<PAGE>
trade or  business within  the United  States  during the  taxable year  or,  in
certain  limited circumstances, a  prior taxable year to  which income, gain, or
loss from the Partnership is treated as effectively connected).
 
    Pursuant to a "safe harbor" provision of the Code, a Foreign Limited Partner
would not be  engaged in a  trade or  business within the  United States  solely
because such Foreign Limited Partner is a partner of a partnership which effects
transactions  in  the United  States in  commodities  for the  partnership's own
account, as long as the partnership is  not a dealer in commodities and as  long
as the partnership only trades commodities which are of a kind customarily dealt
in  on an  organized commodity  exchange in  transactions of  a kind customarily
consummated on such an exchange. The Partnership has been advised by its counsel
that, in  such counsel's  opinion,  the Partnership's  commodities  transactions
should  satisfy the safe harbor, and that  owning an interest in the Partnership
should not,  in such  counsel's  opinion, by  itself,  cause a  Foreign  Limited
Partner  to be engaged in  a trade or business within  the United States. In the
event that future Partnership transactions are  not covered by the safe  harbor,
there  is a risk that  all of a Foreign  Limited Partner's distributive share of
income of the  Partnership would be  treated as effectively  connected with  the
conduct  of a trade or business in the  United States and taxed at regular rates
(discussed previously) and, in the case of a Foreign Limited Partner which is  a
foreign  corporation, an  additional 30% branch  profits tax  (unless reduced or
eliminated by treaty).
 
    If a Foreign  Limited Partner is  a dealer in  commodities, or otherwise  is
engaged  in a  U.S. trade  or business, and  if income,  gain, or  loss from the
Partnership is treated as effectively connected with such trade or business, the
Partnership may be required to withhold tax on income allocable to such  Foreign
Limited  Partner and remit  to the Internal  Revenue Service an  amount equal to
39.6% (35% for corporations) of the amount of such effectively connected taxable
income allocable  to the  Foreign  Limited Partner.  Any amounts  remitted  will
constitute  a  refundable credit  against the  Foreign Limited  Partner's United
States federal income tax liability, which can be claimed on the Foreign Limited
Partner's United States federal income tax return.
 
    A foreign  person generally  is subject  to a  30% withholding  tax  (unless
reduced  or exempted by treaty) on certain  types of United States source income
that are not effectively connected with the conduct of a United States trade  or
business,  such as certain interest-bearing obligations, the income attributable
to which is not exempt from tax. This tax must be withheld by the person  having
control  over the  payment of such  income. Accordingly, the  Partnership may be
required to withhold  tax on  items of  such income  which are  included in  the
distributive  share (whether or  not actually distributed)  of a Foreign Limited
Partner. However,  30%  withholding  is  not  required  in  respect  of  certain
interest-bearing  obligations, such  as "portfolio  interest" obligations issued
after July  18, 1984  (if procedural  requirements are  complied with).  If  the
Partnership  is required  to withhold  tax on such  income of  a Foreign Limited
Partner, the General Partner may pay such tax  out of its own funds and then  be
reimbursed  out of the proceeds of any distribution to or redemption of Units by
the Foreign Limited Partner.
 
    The estate of  a deceased  Foreign Limited Partner  may be  liable for  U.S.
estate tax and may be required to obtain an estate tax release from the Internal
Revenue Service in order to transfer the Units of such Foreign Limited Partner.
 
    FOREIGN  PERSONS  SHOULD  CONSULT  THEIR OWN  TAX  ADVISERS  BEFORE DECIDING
WHETHER TO INVEST IN THE PARTNERSHIP.
 
    TAX ELECTIONS.  The Code provides  for optional adjustments to the basis  of
Partnership  property upon  distributions of  Partnership property  to a Partner
(Section 734) and  transfers of Units,  including transfers by  reason of  death
(Section  743), provided that  a Partnership election has  been made pursuant to
Section 754.  As a  result of  the complexities  and added  expense of  the  tax
accounting  required to implement such an election, the General Partner does not
presently intend to make such an  election. Therefore, any benefits which  might
be available to the Partners by reason of such an election will be foreclosed.
 
                                       82
<PAGE>
    TAX  RETURNS AND  INFORMATION.   The Partnership  will file  its information
return using the accrual method of accounting. Within 90 days after the close of
the Partnership's  taxable  year,  the Partnership  will  furnish  each  Limited
Partner (and any assignee of the Units of any Limited Partner) copies of (i) the
Partnership's  Schedule K-1 indicating the  Limited Partner's distributive share
of tax items and (ii) such additional information as is reasonably necessary  to
permit the Limited Partners to prepare their own federal and state tax returns.
 
    PARTNERSHIP'S  TAX ACCOUNTING.  The Partnership has the calendar year as its
taxable year.
 
    UNRELATED BUSINESS TAXABLE INCOME OF EMPLOYEE BENEFIT PLAN LIMITED  PARTNERS
AND  OTHER TAX-EXEMPT INVESTORS.  Income allocated to a Limited Partner which is
an employee benefit plan or other tax-exempt entity should not be subject to tax
under Section 511 of the Code. Such investors should see "Purchases by  Employee
Benefit Plans--ERISA Considerations."
 
TAX AUDITS
 
    All Partners are required under the Code to report all the Partnership items
on  their own returns consistently with the treatment by the Partnership, unless
they  file  a  statement  with  the  Internal  Revenue  Service  disclosing  the
inconsistencies.  Adjustments in tax liability with respect to Partnership items
will be made at  the Partnership level. The  General Partner will represent  the
Partnership  during  any audit  and  in any  dispute  with the  Internal Revenue
Service. Each Limited Partner in the Partnership will be informed by the General
Partner of the  commencement of  an audit of  the Partnership.  In general,  the
General  Partner may enter into a settlement agreement with the Internal Revenue
Service on behalf of, and binding upon, the Limited Partners. However, prior  to
settlement,  a Limited  Partner may file  a statement with  the Internal Revenue
Service stating that the General Partner  does not have the authority to  settle
on behalf of such Limited Partner.
 
    The  period for assessing  a deficiency against a  partner in a partnership,
such as the  Partnership, with respect  to a  partnership item is  the later  of
three  years after the partnership files its  return or, if the name and address
of the partner does  not appear on  the partnership return,  one year after  the
Internal  Revenue Service is furnished with the name and address of the partner.
In addition, the General Partner may consent on behalf of the Partnership to the
extension of the period for assessing a deficiency with respect to a Partnership
item. As a result, a Limited Partner's federal income tax return may be  subject
to  examination and adjustment by the Internal Revenue Service for a Partnership
item more than three years after it has been filed.
                              -------------------
 
    All of the foregoing  statements are based upon  the existing provisions  of
the   Code  and  the   regulations  promulgated  thereunder   and  the  existing
administrative and judicial  interpretations thereof. It  is emphasized that  no
assurance can be given that legislative, administrative or judicial changes will
not occur which will modify such statements.
 
    The  foregoing statements are  not intended as a  substitute for careful tax
planning, particularly since certain of  the federal income tax consequences  of
purchasing an interest in the Partnership may not be the same for all taxpayers.
There  can be no assurance that the Partnership's tax return will not be audited
by the Internal Revenue  Service or that  no adjustments to  the return will  be
made  as a  result of such  audits. If  an audit results  in adjustment, Limited
Partners may  be required  to file  amended  returns and  their returns  may  be
audited.  Accordingly, prospective purchasers of  an interest in the Partnership
are urged to consult their tax advisers with specific reference to their own tax
situation under federal law  and the provisions of  applicable state, local  and
foreign laws before subscribing for Units.
 
                       STATE AND LOCAL INCOME TAX ASPECTS
 
    In addition to the federal income tax consequences for individuals described
under  "Material Federal Income  Tax Considerations" above,  the Partnership and
its Limited Partners may be subject to various state and local taxes. A  Limited
Partner's  distributive share of the realized  profits of the Partnership may be
required to be included in determining his reportable income for state or  local
tax
 
                                       83
<PAGE>
purposes.  Furthermore, state and local tax  laws may not reflect recent changes
made to  the federal  income tax  law and  hence may  be inconsistent  with  the
federal  income treatment  of gains  and losses  arising from  the Partnership's
transactions  in  Section  1256  contracts.  Accordingly,  prospective   Limited
Partners should consult with their own tax advisers concerning the applicability
of state and local taxes to an investment in the Partnership.
 
    The  General  Partner has  been advised  by  its legal  counsel, Cadwalader,
Wickersham & Taft, that in such counsel's opinion, the Partnership should not be
liable for New York City unincorporated  business tax. Limited Partners who  are
nonresidents  of New York State  will not be liable  for New York State personal
income tax on such Partners' income from the Partnership. No ruling from the New
York State Department of Taxation and  Finance will be requested regarding  such
matters.  Likewise, Limited Partners who are  nonresidents of New York City will
not be liable for New York City  earnings tax on such Partners' income from  the
Partnership.  New York City residents  may be subject to  New York City personal
income tax on such Partners' income from the Partnership.
 
                              POTENTIAL ADVANTAGES
 
    An investment in the Partnership is  speculative and involves a high  degree
of  risk. The General  Partner and DWR believe  that managed futures investments
(such as the  Partnership) provide  investors with the  potential for  long-term
capital  appreciation (with commensurate risk) and  are appropriate only for the
aggressive growth portion  of an  investor's comprehensive  financial plan.  See
"Risk  Factors."  However, such  an  investment offers  the  following potential
advantages.
 
    INVESTMENT DIVERSIFICATION.   An  investor who  is not  prepared to  make  a
significant  investment  or  spend  substantial  time  trading  various  futures
interests nevertheless may participate in these markets through an investment in
the Partnership, thereby obtaining  diversification from investments in  stocks,
bonds,  and real estate. The General Partner  believes, on the basis of the past
experience of the Partnership, that the profit potential of the Partnership does
not depend upon favorable general economic conditions, and that the  Partnership
is  as likely to be profitable during periods of declining stock, bond, and real
estate markets  as  at  any  other time;  conversely,  the  Partnership  may  be
unprofitable  (as  well as  profitable)  during periods  of  generally favorable
economic conditions. According to a 1983  study, "The Potential Role of  Managed
Commodity-Financial  Futures Accounts (and/or Funds) in Portfolios of Stocks and
Bonds" by the late John  Lintner, Ph.D. of Harvard University,  "Diversification
can  substantially reduce  the risks involved  in portfolio  returns and provide
superior returns relative to the risks  incurred." Further, according to a  1993
research  report by Barclay  Trading Group, "Correlation  Trends Changing in the
'90s," "Monthly returns for  stocks and managed futures  have moved in  opposite
directions in approximately 57% of all months during the past ten years. The two
were  both positive in 31% of  all months, and both negative  in only 12% of the
monthly periods."
 
    The Partnership's  combined benefits  of aggressive  growth potential  (with
commensurate  risk) and diversification can potentially reduce overall portfolio
volatility while  maximizing  profits.  By combining  asset  classes,  investors
strive  to  create a  portfolio mix  that  provides the  potential to  offer the
greatest possible  return within  acceptable levels  of volatility.  While  past
performance is no guarantee of future results, a managed futures investment such
as  the Partnership  may profit  (with commensurate  risk) in  sustained futures
interests market moves, regardless of  their direction, a potential  enhancement
to an investor's overall portfolio.
 
    Each  Trading Advisor's speculative  trading techniques will  be the primary
factors in the Partnership's  future success or  failure. Investors should  note
that there are always two parties to a futures interests contract, consequently,
for  any  gain  achieved  by  one  party  on  a  futures  interests  contract, a
corresponding loss is  suffered by the  other. Therefore, due  to the nature  of
futures  interests trading,  only 50%  of futures  interests held  by all market
participants can experience gain at any one time, without reference to brokerage
commissions and other costs of trading,  which may reduce or eliminate any  gain
that would otherwise be achieved.

<PAGE>
    FUTURES  INTERESTS  TRADED.    The  Partnership  normally  trades  a diverse
portfolio of futures  interests, but  may trade a  greater or  lesser number  of
futures  interests, from time to time.  Each Limited Partner will obtain greater
diversification in  futures  interests traded  than  would be  possible  trading
individually,  unless substantially  more than the  minimum investment described
herein were committed to the futures interests markets.
 
    DIVERSIFIED PROFESSIONAL  TRADING MANAGEMENT.    Trading decisions  for  the
Partnership  are made by  Trading Advisors retained by  the General Partner. See
"The Trading  Advisors."  The  trading  approaches employed  on  behalf  of  the
Partnership  by the Trading Advisors are  not available for investments as small
as the required minimum  investment in the  Partnership. The actual  performance
record   of  the  Partnership  is  set  forth  in  "Performance  Record  of  the
Partnership." No assurance  is given  that the Partnership  will obtain  results
consistent  with  such  performance  or  that  the  Partnership  will  not incur
substantial losses.
 
    A Limited Partner's  investment in  the Partnership is  allocated among  the
Trading  Advisors. This permits  a Limited Partner to  receive the benefits from
different trading approaches employed by the Partnership.
 
    LIMITED LIABILITY.   Unlike an  individual who invests  directly in  futures
interests,  an investor  in the  Partnership cannot  be individually  subject to
margin calls and  cannot lose  more than the  amount of  his unredeemed  capital
contribution,  his share  of undistributed profits,  if any,  and, under certain
circumstances, any distributions and amounts  received upon redemption of  Units
and   interest  thereon.  See  "The  Futures,  Options,  and  Forward  Markets,"
"Redemptions,"  and   "The   Limited  Partnership   Agreement--Nature   of   the
Partnership."
 
    INTEREST  INCOME.   Many commodity brokers  permit accounts  above a certain
size to deposit  margin for futures  interests in the  form of  interest-bearing
obligations,  such as U.S.  Treasury Bills, rather than  cash, thus enabling the
account to earn interest on funds  being used for futures interests trading,  or
such  brokers pay interest at U.S. Treasury Bill  rates on a portion of the cash
deposited in the account. The Partnership's assets will be deposited in  futures
interests trading accounts with DWR as commodity broker. Effective on the day of
the  First Closing, DWR  will credit the Partnership  at month-end with interest
income as if 80%  of the Partnership's  average daily Net  Assets for the  month
were  invested  at  a prevailing  rate  on  U.S. Treasury  Bills.  Generally, an
individual trader would  not receive any  interest on the  funds in his  futures
interests  account  unless  he  committed substantially  more  than  the minimum
investment described  herein.  While  the  Partnership  will  be  credited  with
interest  by DWR  on a portion  of its  assets deposited as  margin as described
above, the form of margin  posted, whether cash or interest-bearing  obligations
(such as U.S. Treasury Bills), does not reduce the risks inherent in the trading
of  futures  interests.  See  "Risk Factors"  and  "Investment  Program,  Use of
Proceeds and Trading Policies."
 
    ADMINISTRATIVE CONVENIENCE.  The Partnership is structured so as to  provide
Limited Partners with numerous services designed to alleviate the administrative
details  involved in engaging  directly in futures  interests trading, including
providing monthly and annual financial reports (showing, among other things, the
Net Asset Value of a Unit, trading profits or losses, and expenses), and all tax
information relating  to  the  Partnership necessary  for  Limited  Partners  to
complete their federal income tax returns.

costs, and  extraordinary expenses),  determined  in accordance  with  generally
accepted  accounting principles consistently applied  under the accrual basis of
accounting. Unless generally accepted  accounting principles require  otherwise,
the  market value of a  commodity interest contract traded  on an exchange shall
mean the settlement  price on  the exchange  on which  the particular  commodity
interest  contract shall be traded by the Partnership on the day with respect to
which Net Assets  shall be  determined, PROVIDED,  HOWEVER, that  if a  contract
could  not have been liquidated on such day due to the operation of daily limits
or other rules  of the  exchange upon  which that  contract shall  be traded  or
otherwise,  the  settlement  price on  the  first  subsequent day  on  which the
contract could have been liquidated shall  be the market value of such  contract
for such day. The market value of a forward

commodity due to favorable price movements as margin specifically to buy or sell
additional positions in the same or related commodity.

expenses,  and  other  fees  and  expenses  (excluding  extraordinary  expenses)
directly  attributable to commodity interest contract trading, with such trading
profits and  items of  decrease determined  from the  end of  the last  calendar
quarter  in which an incentive  fee was earned by the  Trading Advisor or, if no
incentive fee has been earned previously  by the Trading Advisor, from the  date

                          INDEPENDENT AUDITORS' REPORT
 
The Limited Partners and the General Partner
Dean Witter Select Futures Fund L.P.:
 
We  have  audited the  accompanying statements  of  financial condition  of Dean
Witter Select Futures Fund L.P. (the "Partnership") as of December 31, 1995  and
1994 and the related statements of operations, changes in partners' capital, and
cash  flows for each of  the three years in the  period ended December 31, 1995.
These  financial  statements  are   the  responsibility  of  the   Partnership's
management.  Our  responsibility is  to express  an  opinion on  these financial
statements based on our audits.
 
We  conducted  our  audits  in  accordance  with  generally  accepted   auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence  supporting
the  amounts and disclosures in the financial statements. An audit also includes
assessing the  accounting  principles used  and  significant estimates  made  by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our  opinion,  such financial  statements  present fairly,  in  all  material
respects,  the financial position of Dean Witter  Select Futures Fund L.P. as of
December 31, 1995 and 1994 and the results of its operations and its cash  flows

                      DEAN WITTER SELECT FUTURES FUND L.P.
                         NOTES TO FINANCIAL STATEMENTS
                (INFORMATION WITH RESPECT TO 1996 IS UNAUDITED)
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    ORGANIZATION--Dean  Witter Select Futures Fund L.P. (the "Partnership") is a
limited partnership organized to engage in the speculative trading of  commodity
futures  contracts, commodity option contracts  and forward contracts on foreign
currencies. The  general  partner  for the  Partnership  is  Demeter  Management
Corporation  (the  "General  Partner").  The  commodity  broker  is  Dean Witter
Reynolds Inc.  ("DWR").  Both  DWR  and the  General  Partner  are  wholly-owned
subsidiaries of Dean Witter, Discover & Co. The General Partner has retained EMC
Capital  Management,  Inc. ("EMC"),  Rabar Market  Research, Inc.  ("Rabar") and
Sunrise Capital  Management, Inc.  ("Sunrise") as  the trading  advisors of  the
Partnership.
 
    The  General Partner is  required to maintain  a 1% minimum  interest in the
equity of the  Partnership and  income (losses) are  shared by  the General  and
Limited Partners based upon their proportional ownership interests.
 
    During  1993 additional units were offered to the public at a price equal to
100% of the net asset value per unit as of September 30, 1993. This resulted  in
$117,667,866 being added to the Partnership.
 
    BASIS  OF ACCOUNTING--The preparation of  financial statements in conformity
with generally  accepted  accounting  principles  requires  management  to  make
estimates  and assumptions  that affect  the reported  amounts in  the financial
statements.
 
    REVENUE RECOGNITION--Commodity  futures  contracts,  commodity  options  and
forward  contracts on foreign  currencies are open  commitments until settlement
date. They are valued  at market and the  resulting unrealized gains and  losses
are reflected in income. Monthly, DWR pays the Partnership interest income based
upon  80% of the average daily  Net Assets for the month  at a rate equal to the
average yield  on 13-week  U.S. Treasury  bills issued  during such  month.  For
purposes  of such interest  payments, Net Assets  do not include  monies due the
Partnership on forward contracts and other commodity interests, but not actually
received.
 
    NET INCOME (LOSS) PER UNIT--Net income (loss) per Unit is computed using the
weighted average number of units outstanding during the period.
 
    EQUITY  IN  COMMODITY  FUTURES  TRADING  ACCOUNTS--The  Partnership's  asset
"Equity  in Commodity futures  trading accounts" consists of  cash on deposit at
DWR to be used as margin for trading  and the net asset or liability related  to
unrealized  gains or losses on  open contracts and the  net option premiums paid
and/or received.  The asset  or liability  related to  the unrealized  gains  or
losses on forward contracts is presented as a net amount because the Partnership
has a master netting agreement with DWR.
 
    BROKERAGE   COMMISSIONS   AND  RELATED   TRANSACTION  FEES   AND  COSTS--The
Partnership accrues brokerage commissions on a  half-turn basis at 80% of  DWR's
published  non-member rates,  to a  maximum of 3/4  of 1%  per month  of the Net
Assets allocated to each trading advisor  as defined in the Limited  Partnership
Agreement.
 
    Transaction   fees  and  costs  are  accrued  on  a  half-turn  basis.  Such
transaction fees and costs, exclusive of  "give-up" fees, are capped at 1/12  of
1% per month of the Net Assets allocated to each trading advisor.
 
    OPERATING  EXPENSES--The Partnership bears all operating expenses related to
its trading activities, to a maximum of 1/4 of 1% annually of the  Partnership's
average month-end Net Assets. These
 
                                      F-6
<PAGE>
include  filing fees,  clerical, administrative,  auditing, accounting, mailing,
printing and other  incidental operating  expenses as permitted  by the  Limited
Partnership  Agreement. In addition, the Partnership incurs a monthly management
fee and  may  incur  an incentive  fee.  The  General Partner  bears  all  other
operating expenses.
 
    REDEMPTIONS--Effective  October 1, 1993 Limited  Partners are able to redeem
some or all of their Units at 100% of  the Net Asset Value per Unit at the  last
day of any month that is at least six months after the closing at which a client
first  became  a  limited partner,  upon  five  business day  advance  notice by
redemption form to the General Partner. However, any Units redeemed at or  prior
to  the end of the  twelfth, eighteenth, or twenty  fourth full months following
the closing  at  which such  person  first becomes  a  limited partner,  may  be
assessed  a redemption charge  equal to 3%,  2% or 1%,  respectively, of the Net
Asset Value per Unit on  the date of such redemption.  Prior to October 1,  1993
redemptions  were  restricted  to  the calendar  quarter.  Limited  Partners who
obtained their Units via an exchange  from another DWR sponsored commodity  pool
are not subject to the six month holding period or the redemption charges.
 
    DISTRIBUTIONS--Distributions,  other than on redemptions  of Units, are made
on a  pro-rata  basis  at  the  sole  discretion  of  the  General  Partner.  No
distributions have been made to date.
 
    INCOME   TAXES--No  provision  for  income  taxes   has  been  made  in  the
accompanying financial statements, as partners are individually responsible  for
reporting  income or loss based upon their respective share of the Partnership's
revenues and expenses for income tax purposes.
 
    DISSOLUTION OF THE PARTNERSHIP--The  Partnership will terminate on  December
31,  2025 or at an  earlier date if certain conditions  set forth in the Limited
Partnership Agreement occur.
 
2.  RELATED PARTY TRANSACTIONS
 
    The Partnership's cash is on deposit with DWR in commodity trading  accounts
to  meet margin  requirements as  needed. DWR  pays interest  on these  funds as
described in Note 1. Under its Customer Agreement with DWR, the Partnership pays
DWR brokerage commissions as described in Note 1.
 
3.  TRADING ADVISORS
 
    Compensation to EMC, Rabar and Sunrise  consists of a management fee and  an
incentive fee as follows:
 
    MANAGEMENT  FEE--The Partnership pays a monthly  management fee equal to 1/4
of 1% per  month of the  Partnership's adjusted  Net Assets, as  defined in  the
Limited Partnership Agreement, as of the last day of each month.
 
    INCENTIVE  FEE--The Partnership will  pay a quarterly  incentive fee to each
trading advisor equal to  17.5% of the trading  advisor's "Trading Profits",  as
defined  in the  Limited Partnership  Agreement, experienced  by the  Net Assets
allocated to such trading advisor as of  the end of each calendar quarter. If  a
trading  advisor has experienced "Trading Losses"  with respect to its allocated
Net Assets at the time of a supplemental closing, the trading advisor must  earn
back  such losses plus a  pro rata amount related to  the funds allocated to the
trading advisor at a supplemental closing before the trading advisor is eligible
for an incentive  fee. Such  incentive fee  is accrued  in each  month in  which
"Trading  Profits"  occurs.  In  those months  in  which  "Trading  Profits" are
negative, previous  accruals,  if  any,  during the  incentive  period  will  be
reduced.  In those instances  in which a Limited  Partner redeems an investment,
the incentive fee (if earned  through a redemption date) is  to be paid to  such
advisor on those redemptions in the month of such redemptions.

4.  FINANCIAL INSTRUMENTS
 
    The  Partnership trades futures,  options and forward  contracts in interest
rates, stock indices, commodities,  currencies, petroleum, and precious  metals.
Futures  and forwards represent contracts for  delayed delivery of an instrument
at a specified date and  price. Risk arises from changes  in the value of  these
contracts  and the  potential inability of  counterparties to  perform under the
terms of  the contracts.  There  are numerous  factors which  may  significantly
influence   the  market  value  of  these  contracts,  including  interest  rate
volatility. At June  30, 1996,  December 31, 1995  and December  31, 1994,  open
contracts were:

</TABLE>
 
    A  portion of  the amounts  indicated as  off-balance-sheet risk  in forward
foreign currency contracts is due to offsetting forward commitments to  purchase
and  to sell the same currency on the same date in the future. These commitments
are economically offsetting, but are not offset in the forward market until  the
settlement date.
 
    The  unrealized  gains on  open  contracts are  reported  as a  component of
"Equity in Commodity futures  trading accounts" on  the Statements of  Financial
Condition  and totaled $4,861,543, $17,428,211 and $22,085,555 at June 30, 1996,
and December 31, 1995 and 1994, respectively.
 
    Of the $4,861,543 net  unrealized gain on open  contracts at June 30,  1996,
$4,733,944  related to exchange-traded futures contracts and $127,599 related to
off-exchange-traded  forward  currency   contracts.  Of   the  $17,428,211   net
unrealized  gain on open contracts at  December 31, 1995, $16,901,032 related to
exchange-traded futures contracts  and $527,179  related to  off-exchange-traded
forward  currency  contracts. Of  the $22,085,555  net  unrealized gain  on open
contracts at December 31, 1994,  $22,292,720 related to exchange-traded  futures
contracts   and  $(207,165)  related  to  off-exchange-traded  forward  currency
contracts.
 
    Exchange-traded futures contracts held by the Partnership at June 30,  1996,
and  December 31, 1995 and 1994 mature  through June 1997, and December 1996 and
September 1995,  respectively.  Off-exchange-traded forward  currency  contracts
held  by the Partnership at June 30, 1996, and December 31, 1995 and 1994 mature
through July  1996, January  1996  and March  1995, respectively.  The  contract
amounts  in the above table represent the Partnership's extent of involvement in
the particular class of financial instrument, but not the credit risk associated
with  counterparty  nonperformance.  The  credit  risk  associated  with   these
instruments  is limited to the amounts reflected in the Partnership's Statements
of Financial Condition.
 
    The Partnership  also  has credit  risk  because  DWR acts  as  the  futures
commission  merchant  or the  sole  counterparty, with  respect  to most  of the
Partnership's assets. Exchange-traded futures and options
 
                                      F-8
<PAGE>
contracts are  marked to  market on  a  daily basis,  with variations  in  value
settled on a daily basis. DWR, as the futures commission merchant for all of the
Partnership's   exchange-traded  futures  contracts,  is  required  pursuant  to
regulations of the Commodity  Futures Trading Commission  to segregate from  its
own assets and for the sole benefit of its commodity customers all funds held by
DWR  with respect to  exchange-traded futures and  option contracts including an
amount equal to the net unrealized gain on all open futures and option contracts
which funds  totaled $145,997,178,  $178,033,694 and  $169,419,850 at  June  30,
1996,  and  December  31,  1995  and 1994,  respectively.  With  respect  to the
Partnership's off-exchange-traded forward currency contracts, there are no daily
settlements of variations in value nor  is there any requirement that an  amount
equal  to  the net  unrealized  gain on  open  forward and  option  contracts be
segregated.  With  respect   to  those   off-exchange-traded  forward   currency
contracts, the Partnership is at risk to the ability of DWR, the counterparty on
all such contracts, to perform.
 
    For  the six months ended June 30, 1996, the average fair value of financial
instruments held for trading purposes was as follows:

5.  SUBSEQUENT EVENTS (UNAUDITED)
    
 
   
    On  August  13,  1996,  the General  Partner  reopened  the  Partnership for
additional investment and registered with the Securities and Exchange Commission
60,000 Units to be offered to investors for a limited time in a public offering.
    
 
   
    Effective as of  September 1,  1996, brokerage  commissions and  transaction
fees  chargeable to the Partnership were capped at  13/20 of 1% per month of the
Partnership's month-end  Net  Assets  (as defined  in  the  Limited  Partnership
Agreement) allocated to each Trading Advisor.
    
 
   
    Effective  on the day of  the First Closing in  the new public offering, DWR
will credit the Partnership with interest at the rate earned by DWR on its  U.S.
Treasury  Bill  investments with  customer  segregated funds  as  if 80%  of the
Partnership's assets were invested in U.S. Treasury Bills.
    
 
   
    On September 6, 10, and 20, 1996, similar purported class actions were filed
in the Superior  Court of the  State of  California, County of  Los Angeles,  on
behalf  of all  purchasers of interests  in limited  partnership commodity pools
sold by DWR. Named defendants include DWR, Demeter Management Corporation,  Dean
Witter  Futures and Currency  Management Inc., Dean Witter,  Discover & Co. (all
such  parties  referred  to  hereafter  as  the  "Dean  Witter  Parties"),   the
Partnership,  certain other limited partnership commodity pools of which Demeter
is the general partner,  and certain trading advisors  to those pools. Also,  on
September  18 and  20, 1996  similar purported class  actions were  filed in the
Supreme Court of the State of New York, New York County, against the Dean Witter
Parties and certain trading advisors on behalf of all purchasers of interests in
various limited  partnership  commodity  pools sold  by  DWR.  Generally,  these
complaints  allege,  among other  things, that  the defendants  committed fraud,
deceit, misrepresentation,  breach  of  fiduciary duty,  fraudulent  and  unfair
business practices, unjust

enrichment,  and conversion  in connection  with the  sale and  operation of the
various limited  partnership commodity  pools. The  complaints seek  unspecified
amounts  of compensatory and  punitive damages and other  relief. It is possible
that additional similar actions may  be filed and that,  in the course of  these
actions,  other parties  could be added  as defendants. The  Dean Witter Parties
believe that they  and the Partnership  have strong defenses  to, and they  will
vigorously  contest,  the  actions.  Although  the  ultimate  outcome  of  legal
proceedings cannot be predicted with certainty, it is the opinion of  management
of  the Dean Witter Parties  that the resolution of the  actions will not have a
material adverse effect on the financial condition or the results of  operations
of the Partnership.

                          INDEPENDENT AUDITORS' REPORT
 
   
To the Board of Directors of
Demeter Management Corporation:
    
 
We  have audited the  accompanying statements of  financial condition of Demeter
Management Corporation (a  wholly-owned subsidiary  of Dean  Witter, Discover  &
Co.)  (the "Company")  as of  December 31,  1995 and  1994. These  statements of
financial condition  are the  responsibility of  the Company's  management.  Our
responsibility  is to express an opinion  on these financial statements based on
our audits.
 
We  conducted  our  audits  in  accordance  with  generally  accepted   auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence  supporting
the  amounts and disclosures in the financial statements. An audit also includes
assessing the  accounting  principles used  and  significant estimates  made  by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, such  statements of financial condition  present fairly, in  all
material  respects, the financial position  of Demeter Management Corporation as
of December 31, 1995 and 1994  in conformity with generally accepted  accounting
principles.

                   NOTES TO STATEMENTS OF FINANCIAL CONDITION
                (INFORMATION WITH RESPECT TO 1996 IS UNAUDITED)
 
1.  BUSINESS DESCRIPTION AND SIGNIFICANT ACCOUNTING POLICIES
 
    Demeter  Management Corporation ("Demeter") is  a wholly-owned subsidiary of
Dean Witter, Discover & Co. (the "Parent").
 
    Demeter manages the following commodity pools as their sole general partner:
Dean Witter Cornerstone Fund II, Dean  Witter Cornerstone Fund III, Dean  Witter
Cornerstone Fund IV, Columbia Futures Fund, Dean Witter Diversified Futures Fund
Limited  Partnership ("DWDFF"),  Dean Witter  Diversified Futures  Fund II L.P.,
Dean  Witter  Diversified  Futures  Fund  III  L.P.,  Dean  Witter  Multi-Market
Portfolio, L.P. (formerly Dean Witter Principal Guaranteed Fund L.P. ("DWPGF")),
Dean Witter Principal Guaranteed Fund II L.P. ("DWPGFII"), Dean Witter Principal
Plus  Fund L.P.,  Dean Witter Principal  Plus Fund Management  L.P., Dean Witter
Portfolio Strategy Fund  L.P. (formerly  Dean Witter  Principal Secured  Futures
Fund  L.P.), Dean Witter Select Futures  Fund L.P. ("DWSFF"), Dean Witter Global
Perspective Portfolio L.P., Dean  Witter World Currency  Fund L.P., Dean  Witter
Institutional  Balanced  Portfolio  Account I  L.P.,  Dean  Witter Institutional
Account II  L.P.,  DWFCM International  Access  Fund L.P.,  Dean  Witter  Anchor
Institutional  Balanced Portfolio Account I  L.P., Dean Witter Spectrum Balanced
L.P., Dean Witter Spectrum Strategic L.P., Dean Witter Spectrum Technical  L.P.,
DWR Chesapeake L.P. and DWR Institutional Balanced Portfolio Account III L.P.
 
   
    In November of 1995, Demeter entered into a limited partnership agreement as
General  Partner in  DWR/JWH Futures Fund  L.P. ("JWH"), a  commodity pool which
offered units to investors in an initial private offering period ending  January
31,  1996 and began trading on February 1, 1996. Demeter's initial investment in
JWH was $75,000.
    
 
   
    Management terminated DWPGFII as of  March 31, 1996. DWPGFII was  liquidated
and holders of units as of March 31, 1996 received a final distribution equal to
the  net asset value per unit on that date multiplied by their respective number
of units.
    
 
    Each of the commodity pools is a limited partnership organized to engage  in
the  speculative trading  of commodity  futures contracts,  forward contracts on
foreign currencies and other commodity interests.
 
    Demeter reopened DWDFF for additional investment and on June 29, 1995  DWDFF
registered  with the Securities and Exchange  Commission 75,000 units which were
offered to investors for a limited time in a public offering.
 
    INCOME TAXES--The  results of  operations  of Demeter  are included  in  the
consolidated  federal income  tax return  of the  Parent. Income  tax expense is
calculated on a separate company basis.     BASIS OF ACCOUNTING--The preparation
of  financial  statements  in  conformity  with  generally  accepted  accounting
principles requires management to make estimates and assumptions that affect the
reported amounts in the financial statements.
 
2.  INVESTMENTS IN AFFILIATED PARTNERSHIPS
 
    The limited partnership agreement of each commodity pool requires Demeter to
maintain  a general  partnership interest in  each partnership,  generally in an
amount equal  to,  but  not  less  than, 1  percent  of  the  aggregate  capital
contributed to the partnership by all partners.

by  Demeter at June  30, 1996, December 31,  1995 and December  31, 1994 were as

</TABLE>
 
    Demeter's investments  in  the above  limited  partnerships are  carried  at
market   value  with  changes  in  such  market  value  reflected  currently  in
operations.
 
3.  PAYABLE TO PARENT
 
    The payable  to Parent  is primarily  for amounts  due for  the purchase  of
partnership  investments and income tax payments made by the Parent on behalf of
Demeter.
 
4.  NET WORTH REQUIREMENT
 
    At June 30,  1996, December  31, 1995  and 1994,  Demeter held  non-interest
bearing  notes from  the Parent  that were payable  on demand.  These notes were
received  in  connection  with  additional  capital  contributions   aggregating
$111,070,000, $111,070,000 and $98,070,000, respectively.
 
    The limited partnership agreement of each commodity pool requires Demeter to
maintain  its  net  worth  at  an  amount  not  less  than  10%  of  the capital
contributions by  all partners  in each  pool in  which Demeter  is the  general
partner  (15%  if the  capital contributions  to any  partnership are  less than
$2,500,000, or $250,000, whichever is less).
 
    In  calculating  this  requirement,  Demeter's  interests  in  each  limited
partnership  and any amounts receivable from or payable to such partnerships are
excluded from net worth.  Notes receivable from the  Parent are included in  net
worth for purposes of this calculation.
 
   
5.  SUBSEQUENT EVENTS (UNAUDITED)
    
 
   
    On  August 13, 1996, management reopened DWSFF for additional investment and
registered with  the  Securities and  Exchange  Commission 60,000  Units  to  be
offered to investors for a limited time in a public offering.
    
 
   
    On September 6, 10, and 20, 1996, similar purported class actions were filed
in  the Superior  Court of the  State of  California, County of  Los Angeles, on
behalf of all  purchasers of  interests in limited  partnership commodity  pools
sold by Dean Witter Reynolds Inc. ("DWR"). Named defendants include DWR, Demeter
Management  Corporation, Dean Witter Futures  and Currency Management Inc., Dean
Witter, Discover &  Co. (all  such parties referred  to hereafter  as the  "Dean
Witter  Parties"), certain limited partnership  commodity pools of which Demeter
is the general partner,  and certain trading advisors  to those pools. Also,  on
September  18 and  20, 1996  similar purported class  actions were  filed in the
Supreme Court of the State of New York, New York County, against the Dean Witter
Parties and certain trading advisors on behalf of all purchasers of interests in
various limited  partnership  commodity  pools sold  by  DWR.  Generally,  these
complaints  allege,  among other  things, that  the defendants  committed fraud,
deceit, misrepresentation,  breach  of  fiduciary duty,  fraudulent  and  unfair
business  practices, unjust  enrichment, and  conversion in  connection with the
sale and  operation of  the  various limited  partnership commodity  pools.  The
complaints  seek unspecified  amounts of  compensatory and  punitive damages and
other relief. It is  possible that additional similar  actions may be filed  and
that,  in  the  course  of  these  actions,  other  parties  could  be  added as
defendants. The Dean Witter Parties believe  that they have strong defenses  to,
and  they will vigorously contest, the actions. Although the ultimate outcome of
legal proceedings  cannot be  predicted with  certainty, it  is the  opinion  of
management  of the Dean Witter  Parties that the resolution  of the actions will
not have a material adverse effect on the financial condition of any of the Dean
Witter Parties.

this Agreement, whether in counterpart, by separate instrument, or otherwise, as
limited partners  (collectively  "Limited  Partners"; the  General  Partner  and
Limited Partners may be collectively referred to herein as "Partners").
 
                              W I T N E S S E T H:
 
    WHEREAS,  the parties  hereto desire to  form a limited  partnership for the
purpose of engaging in the speculative trading of futures interests;

Revised  Uniform Limited Partnership Act,  as amended and in  effect on the date
hereof (the "Act"). The  name of the limited  partnership is Dean Witter  Select
Futures  Fund L.P.  (the "Partnership").  The General  Partner may,  without the
approval of the Limited Partners, change  the name of the Partnership, or  cause

the  Act  and  shall execute,  file,  record,  and publish  as  appropriate such
amendments, assumed  name certificates,  and other  documents as  are or  become
necessary  or advisable in connection with  the operation of the Partnership, as
determined by the General  Partner, and shall take  all steps which the  General
Partner  may deem  necessary or  advisable to  allow the  Partnership to conduct
business as a limited partnership where the Partnership conducts business in any
jurisdiction and to otherwise  provide that Limited  Partners will have  limited
liability  with  respect  to  the  activities of  the  Partnership  in  all such
jurisdictions, and to  comply with  the law  of any  jurisdiction. Each  Limited
Partner  hereby undertakes to furnish to the General Partner a power of attorney
and such additional information as the  General Partner may request to  complete
such  documents  and  to execute  and  cooperate  in the  filing,  recording, or
publishing of such documents as the General Partner determines appropriate.

and  any  rights pertaining  thereto  (hereinafter referred  to  collectively as
"futures interests") and securities (such as United States Treasury  securities)
approved by the Commodity Futures Trading Commission (the "CFTC") for investment
of  customer  funds,  and to  engage  in  all activities  incident  thereto. The
objective of the Partnership's  business is appreciation  of its assets  through
speculative  trading. The  Partnership may pursue  this objective  in any lawful
manner consistent with the Partnership's  trading policies. The Partnership  may
engage  in  the  foregoing  activities either  directly  or  through  any lawful
transaction or any lawful activity into which a limited partnership may enter or
in which  a limited  partnership  may engage  under the  laws  of the  State  of
Delaware;  PROVIDED, that  such transactions  or activities  do not  subject the
Limited Partners to any  liability in excess of  the limited liability  provided
for herein and contemplated by the Act.
 
4.  TERM; DISSOLUTION; FISCAL YEAR.
 
    (A)   TERM.  The  term of the Partnership shall  commence upon the filing of
the Certificate of Limited Partnership in  the Office of the Secretary of  State
of the State of Delaware and shall end upon the first to occur of the following:
(a)  December  31, 2025;  (b)  withdrawal, insolvency,  bankruptcy, dissolution,
liquidation, or termination of the General  Partner, unless the business of  the
Partnership  shall be continued by any remaining or successor general partner(s)
in accordance with the provisions hereof; (c) receipt by the General Partner  of
a  notice setting forth an election to terminate and dissolve the Partnership at
a specified time  by Limited  Partners owning  more than  50% of  the Units  (as
defined in Section 6) then owned by Limited Partners, which notice shall be sent
by  registered  mail  to the  General  Partner at  least  90 days  prior  to the
effective date of  such termination and  dissolution; (d) a  decline in the  Net
Asset  Value  (as defined  in Section  7(d)(2)) of  a  Unit as  of the  close of
business (as determined by the  General Partner) on any  day to less than  $250;
(e) a decline in the Partnership's Net Assets (as defined in Section 7(d)(1)) as
of the close of business (as determined by the General Partner) on any day to or
less  than  $250,000;  (f)  a  determination by  the  General  Partner  that the
Partnership's  Net  Assets  in  relation  to  the  operating  expenses  of   the
Partnership  make it unreasonable  or imprudent to continue  the business of the
Partnership; (g) the occurrence  of any event which  shall make it unlawful  for
the  existence of the Partnership to be continued; or (h) a determination by the
General Partner to terminate the Partnership following a Special Redemption Date
as described in Section 9.
 
    (B)  DISSOLUTION.  Upon the  occurrence of an event causing the  termination
of   the  Partnership,  the  Partnership   shall  terminate  and  be  dissolved.
Dissolution, payment of  creditors, and  distribution of  the Partnership's  Net
Assets  shall be  effected as  soon as practicable  in accordance  with the Act,
except that the  General Partner  and each  Limited Partner  (and any  assignee)
shall  share in the  Net Assets of  the Partnership pro  rata in accordance with
such Partner's respective capital account, less any amount owing by such Partner
(or assignee) to the Partnership. The  General Partner shall, at its option,  be
entitled to supervise the liquidation of the Partnership.
 
    Nothing  contained in  this Agreement shall  impair, restrict,  or limit the
rights and powers of the Partners under the law of the State of Delaware and any
other jurisdiction  in which  the Partnership  shall be  conducting business  to
reform   and  reconstitute   themselves  as  a   limited  partnership  following
dissolution of the Partnership, either  under provisions identical to those  set
forth herein or any others which they shall deem appropriate.
 
    (C)  FISCAL YEAR.  The fiscal year of the Partnership shall begin on January
1 of each year and end on the following December 31.
 
5.  NET WORTH OF GENERAL PARTNER.
 
    The  General Partner agrees that at all times, as long as it remains General
Partner of the Partnership,  it shall maintain  its Net Worth  at an amount  not
less  than 10% of the total contributions to the Partnership by all Partners and
to any other limited partnership for which  it acts as a general partner by  all
such  partnership's partners; PROVIDED, HOWEVER, that if the total contributions
to the Partnership by all Partners, or  to any limited partnership for which  it
acts  as a general partner by all  partners, are less than $2,500,000, then with
respect to  the  Partnership  and  any such  limited  partnership,  the  General
 
                                      A-2
<PAGE>
Partner  shall maintain its Net Worth at an  amount of at least 15% of the total
contributions to the Partnership by all Partners and of the total  contributions
to  any such limited partnership  for which it acts as  a general partner by all
such partnership's partners or $250,000, whichever is the lesser; and, PROVIDED,
FURTHER, that in no  event shall the  General Partner's Net  Worth be less  than
$50,000.  For the purposes of  this Section 5, Net  Worth shall be calculated in
accordance with generally  accepted accounting principles,  except as  otherwise
specified in this Section 5, with all current assets based on their then current
market values. The interests owned by the General Partner in the Partnership and
any  other partnerships for which it acts as a general partner and any notes and
accounts receivable and payable  to any limited partnership  in which it has  an
interest shall not be included as an asset in calculating its Net Worth, but any
notes receivable from an affiliate (as such term is defined in Regulation S-X of
the rules and regulations of the Securities and Exchange Commission (the "SEC"))
of the General Partner or letters of credit may be included.
 
    The  General Partner agrees  that it shall  not be a  general partner of any
limited partnership other than the Partnership unless, at all times when it is a
general partner of any such additional limited partnership, its Net Worth is  at
least equal to the Net Worth required by the preceding paragraph of this Section
5.
 
    The  requirements of the preceding  two paragraphs of this  Section 5 may be
modified by the General Partner at its option, without notice to or the  consent
of the Limited Partners, PROVIDED THAT: (a) such modification does not adversely
affect  the  interests of  the  Limited Partners,  and  (b) the  General Partner
obtains a written  opinion of  counsel for  the Partnership  that such  proposed
modification:   (i)  will  not  adversely   affect  the  classification  of  the
Partnership as a  partnership for  federal income  tax purposes,  (ii) will  not
adversely  affect the status  of the Limited Partners  as limited partners under
the Act, and (iii) will not violate any applicable state securities or Blue  Sky
law  or any rules, regulations, guidelines,  or statements of policy promulgated
or applied thereunder; PROVIDED, HOWEVER,  that the General Partner's net  worth
may  not be reduced  below the lesser of  (A) the net  worth required by Section
II.B of the Guidelines for Registration  of Commodity Pool Programs, as  adopted
in  revised form  by the  North American  Securities Administrators Association,
Inc. in September, 1993 (the "NASAA Guidelines"), and (B) the net worth required
by such Guidelines as in effect on the date of such proposed modification.
 
6.  CAPITAL CONTRIBUTIONS AND OFFERING OF UNITS OF LIMITED PARTNERSHIP INTEREST.
 
    The  General  Partner  is  herewith  contributing  $1,000  in  cash  to  the
Partnership  for which it is receiving  one Unit of General Partnership Interest
("Unit of General Partnership  Interest"). At the initial  closing, if any,  for
the acceptance of subscriptions for Units of Limited Partnership Interest in the
Partnership  ("Units" or, individually, a "Unit") during the initial offering of
Units (the  "Initial Closing"),  the  General Partner  shall contribute  to  the
Partnership in $1,000 increments the additional amount in cash that is necessary
to make the General Partner's capital contribution at least equal to the greater
of  (a) 1% of aggregate capital contributions to the Partnership by all Partners
(including the General Partner's contribution) and (b) $25,000. Such  additional
contribution  by the General Partner need  not exceed the amount described above
and shall be evidenced by Units of General Partnership Interest. Thereafter, the
General Partner shall maintain its interest in the capital of the Partnership at
no less than the amount stated above. The General Partner, without notice to  or
consent of the Limited Partners, may withdraw any portion of its interest in the
Partnership  that is in excess of its required interest described above. The net
asset value of  a Unit of  General Partnership  Interest shall at  all times  be
equivalent to the Net Asset Value of a Unit of Limited Partnership Interest.
 
    Interests in the Partnership, other than the General Partnership Interest of
the  General Partner, shall be  Units. The initial Limited  Partner named at the
end of this Agreement is herewith contributing $1,000 in cash to the capital  of
the  Partnership in  consideration for receiving  one Unit.  The initial Limited
Partner agrees to withdraw as a Limited Partner at the Initial Closing, and  the
remaining
 
                                      A-3
<PAGE>
Partners  hereby consent to such withdrawal.  The $1,000 capital contribution of
the initial Limited Partner shall be  returned to him, without interest, and  he
shall have no further rights or obligations as a Limited Partner with respect to
such contribution.
 
    The  General Partner, for and on behalf  of the Partnership, shall issue and
sell Units to persons  desiring to become Limited  Partners, PROVIDED that  such
persons shall be determined by the General Partner to be qualified investors and
their  subscriptions for Units  shall be accepted by  the General Partner, which
acceptance the General  Partner may withhold  in whole  or in part  in its  sole
discretion.  The minimum  subscription for  Units per  subscriber shall  be such
amount as the  General Partner shall  determine from  time to time  in its  sole
discretion.
 
    Following  the  initial  offering of  Units,  the Initial  Closing,  and the
commencement of  trading operations,  the Partnership,  directly and/or  through
Dean  Witter Reynolds Inc. ("DWR") or such  other selling agent or agents as may
be approved by the General Partner, may at any time and from time to time in the
sole discretion of  the General Partner  offer for sale  Units and fractions  of
Units (to the third decimal place) in public and/or private offerings, at prices
per  Unit, in such minimum amounts, for such  periods of time, and on such terms
and conditions as the  General Partner shall determine  in its sole  discretion.
Units  offered during any  subsequent offering shall  be issued and  sold by the
Partnership as of the opening of business (as determined by the General Partner)
on the  first business  day of  a  fiscal quarter  or month  and a  closing  for
subscriptions  received  during such  offering shall  be held  as of  such date;
PROVIDED, HOWEVER, that  the General  Partner may  hold closings  at such  other
times and for such other periods as it shall determine in its sole discretion to
effectuate  such  subsequent offerings.  At each  such closing,  the Partnership
shall issue  and sell  Units  to each  subscriber  whose subscription  shall  be
accepted  by the  General Partner at  a price per  Unit to be  determined by the
General Partner in  its sole  discretion; PROVIDED, HOWEVER,  that the  offering
price  per Unit during any subsequent offering of Units shall not at any time be
less than the Net  Asset Value of a  Unit as of the  opening of business on  the
date  of the  applicable closing at  which such  Unit shall be  issued and sold.
During any  subsequent offering  Units  may be  subscribed  for by  the  General
Partner,  DWR, Dean Witter, Discover  & Co. ("DWD"), any  trading advisor to the
Partnership, and  such persons'  respective shareholders,  directors,  officers,
partners, employees, principals, and affiliates. Subscriptions for Units by such
persons shall not preclude them from receiving compensation from the Partnership
for  services  rendered by  them in  their respective  capacities as  other than
Limited Partners.  No subscriber  for Units  during any  subsequent offering  of
Units shall become a Limited Partner until the General Partner shall: (a) accept
such  subscriber's subscription  at the closing  relating to  such offering; (b)
execute this Agreement  on behalf of  such subscriber pursuant  to the power  of
attorney  in Section 11; and (c)  make an entry on the  books and records of the
Partnership reflecting  that such  subscriber  has been  admitted as  a  Limited
Partner.  Accepted subscribers shall be deemed  Limited Partners at such time as
their admission shall be reflected on the books and records of the Partnership.
 
    In connection with the Partnership's offering of Units, the General Partner,
on behalf  of  the  Partnership, shall:  (a)  cause  to be  filed  one  or  more
Disclosure  Documents and such amendments and supplements thereto as the General
Partner shall deem advisable or  as may be required  by applicable law with  the
CFTC   and  the  National   Futures  Association  ("NFA"),   Forms  D  or  other
applications, notices or forms  with the SEC and  state securities and Blue  Sky
administrators,  and Registration Statements, Prospectuses (as used hereinafter,
the term "Prospectus" shall mean the most recent version of the Prospectus filed
with the  SEC in  connection with  the  offering of  Units, unless  the  context
otherwise  requires) and such amendments and  supplements thereto as the General
Partner shall deem advisable or as may  be required by applicable law, with  the
CFTC, the NFA, the SEC, and the National Association of Securities Dealers, Inc.
(the  "NASD"); (b)  qualify by registration  or exemption  from registration the
Units for sale  under the Blue  Sky and securities  laws of such  states of  the
United  States and such other  jurisdictions as the General  Partner in its sole
discretion shall deem  advisable or as  may be required  by applicable law;  (c)
make   such   arrangements   for  the   sale   of   Units  as   it   shall  deem
 
                                      A-4
<PAGE>
advisable, including engaging DWR or any  other firm as selling agent for  Units
and  entering into a selling agreement with DWR or such other firm; and (d) take
such action with respect to and in order to effectuate the matters described  in
clauses (a) through (c) as it shall deem advisable or necessary.
 
    All  Units subscribed for shall be issued  subject to the collection of good
funds. If, at any time, good funds  representing payment for Units are not  made
available  to the Partnership because a subscriber has provided bad funds in the
form of a bad check or draft or otherwise to DWR or another selling agent which,
in turn,  has deposited  the  subscription amount  with  the escrow  agent,  the
Partnership shall cancel the Units issued to such subscriber represented by such
bad  funds, and the subscriber's name shall be removed as a Limited Partner from
the books and records of the Partnership. Any losses or profits sustained by the
Partnership in connection with its commodity trading allocable to such cancelled
Units shall be deemed a decrease or  increase in Net Assets and allocated  among
the remaining Partners as described in Section 7. Each Limited Partner agrees to
reimburse  the Partnership for any expense  or loss (including any trading loss)
incurred in connection  with the  issuance and  cancellation of  any such  Units
issued to such Limited Partner.
 
7.  ALLOCATION OF PROFITS AND LOSSES; ACCOUNTING; OTHER MATTERS.
 
    (A)   CAPITAL  ACCOUNTS.   A capital account  shall be  established for each
Partner. The initial  balance of  each Partner's  capital account  shall be  the
amount of a Partner's initial capital contribution to the Partnership.
 
    (B)  MONTHLY ALLOCATIONS.  As of the close of business (as determined by the
General  Partner) on the last day  of each calendar month ("Determination Date")
during each fiscal  year of  the Partnership, the  following determinations  and
allocations shall be made:
 
       (1) The  Net Assets of  the Partnership (as  defined in Section 7(d)(1)),
           before accrual of the monthly management fees and quarterly incentive
    fees payable to the trading advisors shall be determined.
 
       (2) The accrued monthly management fees shall then be charged against Net
           Assets.
 
       (3) The accrued quarterly incentive fees, if any, payable to the  trading
           advisors shall then be charged against Net Assets.
 
       (4) Any  increase or  decrease in  Net Assets  (after the  adjustments in
           subparagraphs (2) through (3) above),  over those of the  immediately
    preceding  Determination Date  (or, in the  case of  the first Determination
    Date, the Initial Closing), shall then be credited or charged to the capital
    accounts of each Partner in the ratio that the balance of each account bears
    to the balance of all accounts.
 
       (5) The amount of  any distribution to  a Partner, any  amount paid to  a
           Partner  on redemption  of Units and  any amount paid  to the General
    Partner upon withdrawal of its interest in the Partnership shall be  charged
    to that Partner's capital account.
 
    (C)   ALLOCATION OF PROFIT AND LOSS FOR  FEDERAL INCOME TAX PURPOSES.  As of
the end  of each  fiscal year  of the  Partnership, the  Partnership's  realized
profit  or loss shall be allocated among  the Partners pursuant to the following
subparagraphs for federal income  tax purposes. Such  allocations of profit  and
loss  will be pro rata from net capital gain or loss and net operating income or
loss realized by the Partnership. For United States federal income tax purposes,
a distinction will be made between net short-term gain or loss and net long-term
gain or loss.
 
       (1) Items of ordinary  income (such  as interest  or credits  in lieu  of
           interest)  and expense (such as  the management fees, incentive fees,
    transaction fees  and  costs,  administrative  expenses,  and  extraordinary
    expenses)  shall be  allocated pro  rata among  the Partners  based on their
    respective capital accounts (exclusive of these items of ordinary income  or
    expense)  as of the end of each month  in which the items of ordinary income
    or expense accrued.
 
                                      A-5
<PAGE>
       (2) Net realized  capital gain  or loss  from the  Partnership's  trading
           activities shall be allocated as follows:
 
           (aa)For  the  purpose of  allocating  the Partnership's  net realized
               capital  gain  or  loss  among  the  Partners,  there  shall   be
       established  an allocation account with respect to each outstanding Unit.
       The initial balance of each allocation  account shall be the amount  paid
       by the Partner to the Partnership for the Unit. Allocation accounts shall
       be  adjusted as  of the  end of  each fiscal  year and  as of  the date a
       Partner completely redeems his Units as follows:
 
                (i)Each allocation account shall be  increased by the amount  of
                   income  allocated  to  the  holder of  the  Unit  pursuant to
           subparagraph (c)(1) above and subparagraph (c)(2)(cc) below.
 
               (ii)Each allocation account shall be  decreased by the amount  of
                   expense  or loss allocated to the holder of the Unit pursuant
           to subparagraph (c)(1) above and subparagraph (c)(2)(ee) below and by
           the amount of any  distribution the holder of  the Unit has  received
           with respect to the Unit (other than on redemption of Units).
 
              (iii)When  a Unit is redeemed, the allocation account with respect
                   to such Unit shall be eliminated.
 
           (bb)Net realized  capital  gain  shall be  allocated  first  to  each
               Partner  who has partially  redeemed his Units  during the fiscal
       year up to the excess, if any, of the amount received upon redemption  of
       the Units over the allocation account attributable to the redeemed Units.
 
           (cc)Net  realized capital gain remaining after the allocation thereof
               pursuant to subparagraph (c)(2)(bb) above shall be allocated next
       among all Partners whose capital accounts  are in excess of their  Units'
       allocation  accounts  (after the  adjustments in  subparagraph (c)(2)(bb)
       above) in the  ratio that each  such Partner's excess  bears to all  such
       Partners'  excesses. In the  event that gain to  be allocated pursuant to
       this subparagraph  (c)(2)(cc) is  greater  than the  excess of  all  such
       Partners'  capital accounts over all such allocation accounts, the excess
       will be allocated  among all Partners  in the ratio  that each  Partner's
       capital account bears to all Partners' capital accounts.
 
           (dd)Net  realized  capital  loss  shall be  allocated  first  to each
               Partner who has  partially redeemed his  Units during the  fiscal
       year  up to the excess, if any, of the allocation account attributable to
       the redeemed Units over the amount received upon redemption of the Units.
 
           (ee)Net realized capital loss remaining after the allocation  thereof
               pursuant to subparagraph (c)(2)(dd) above shall be allocated next
       among  all Partners  whose Units'  allocation accounts  are in  excess of
       their capital accounts (after the adjustments in subparagraph  (c)(2)(dd)
       above)  in the ratio  that each such  Partner's excess bears  to all such
       Partners' excesses. In the  event that loss to  be allocated pursuant  to
       this  subparagraph  (c)(2)(ee) is  greater than  the  excess of  all such
       allocation accounts over all such Partners' capital accounts, the  excess
       loss  will  be  allocated  among  all Partners  in  the  ratio  that each
       Partner's capital account bears to all Partners' capital accounts.
 
       (3) The tax allocations prescribed by this Section 7(c) shall be made  to
           each  holder of  a Unit  whether or not  the holder  is a substituted
    Limited Partner. In the event that  a Unit has been transferred or  assigned
    pursuant  to Section 10(a), the allocations  prescribed by this Section 7(c)
    shall be made with respect  to such Unit without  regard to the transfer  or
    assignment,   except  that  in  the  year  of  transfer  or  assignment  the
    allocations prescribed by  this Section  7(c) shall be  divided between  the
    transferor or assignor and the transferee or assignee based on the number of
    months  each held  the transferred  or assigned  Unit. For  purposes of this
    Section 7(c), tax allocations shall be  made to the General Partner's  Units
    of General Partnership Interest on a Unit-equivalent basis.
 
       (4) The allocation of profit and loss for federal income tax purposes set
           forth  herein is intended to allocate  taxable profits and loss among
    Partners generally in the ratio and to the extent
 
                                      A-6
<PAGE>
    that net profit and  net loss are allocated  to such Partners under  Section
    7(b)  hereof  so as  to  eliminate, to  the  extent possible,  any disparity
    between a Partner's capital account and his allocation account with  respect
    to  each Unit then outstanding, consistent  with the principles set forth in
    Section 704(c)(2) of  the Internal  Revenue Code  of 1986,  as amended  (the
    "Code").
 
    (D)  DEFINITIONS; ACCOUNTING.
 
    (1)  NET ASSETS.  The Partnership's "Net Assets" shall mean the total assets
of the Partnership (including, but not limited to, all cash and cash equivalents
(valued  at cost), accrued interest and amortization of original issue discount,
and the market value of all open futures interests positions and other assets of
the Partnership) less the total  liabilities of the Partnership (including,  but
not limited to, one-half of the brokerage commissions that would be payable with
respect  to  the closing  of each  of the  Partnership's open  futures interests
positions, management fees, incentive fees, administrative expenses, transaction
fees and  costs,  and  extraordinary expenses)  determined  in  accordance  with
generally  accepted accounting principles consistently applied under the accrual
basis of  accounting. Unless  generally accepted  accounting principles  require
otherwise,  the market  value of  a futures interest  traded on  a United States
exchange shall mean the settlement price on the exchange on which the particular
futures interest shall be traded by the  Partnership on the day with respect  to
which  Net  Assets shall  be determined;  PROVIDED, HOWEVER,  that if  a futures
interest could not  have been liquidated  on such  day due to  the operation  of
daily  limits or other  rules of the  exchange upon which  that futures interest
shall be traded or otherwise, the  settlement price on the first subsequent  day
on  which the futures  interest could have  been liquidated shall  be the market
value of such  futures interest  for such  day. The  market value  of a  futures
interest  traded on a foreign exchange or  market shall mean its market value as
determined by  the General  Partner on  a basis  consistently applied  for  each
different variety of futures interest.
 
    (2)   NET ASSET VALUE.   The "Net Asset Value" of  a Unit shall mean the Net
Assets allocated to capital accounts represented by Units of Limited Partnership
Interest divided  by  the  aggregate  number of  Units  of  Limited  Partnership
Interest.
 
    (E)    EXPENSES  AND  LIMITATIONS  THEREOF.    DWR  shall  pay  all  of  the
organizational and  offering expenses  of the  Partnership (including,  but  not
limited  to, legal, accounting, and auditing  fees, printing costs, filing fees,
escrow fees,  marketing costs  and expenses,  and other  related expenses),  and
shall not be reimbursed therefor.
 
    The  Partnership  shall pay  all  of its  ordinary  administrative expenses,
including expenses  for  services provided  by  third parties  selected  by  the
General Partner and reimbursement of all out-of-pocket expenses incurred by such
persons  and by the General Partner and  its affiliates in providing services to
the Partnership, subject  to a maximum  of 0.25% per  year of the  Partnership's
average  Net Assets  (calculated on  the basis of  the average  of month-end Net
Assets during each calendar year). The  General Partner or an affiliate  thereof
shall  pay and shall not  be reimbursed for any  such administrative expenses in
excess of such maximum amount. Such expenses shall include legal, accounting and
auditing expenses  (including expenses  incurred in  preparing reports  and  tax
information  to  Limited Partners  and regulatory  authorities and  expenses for
specialized administrative services), printing and duplication expenses, mailing
expenses, and filing fees.  The General Partner shall  not be reimbursed by  the
Partnership  for any costs  incurred by it relating  to office space, equipment,
and staff necessary for Partnership operations and administration of redemptions
of Units. The Partnership  will be obligated to  pay any extraordinary  expenses
(determined  in accordance with generally accepted accounting principles) it may
incur.
 
    The Partnership's assets held by DWR or other commodity brokers as  provided
in  Section 7(i) may be used as margin solely for the Partnership's trading. The
Partnership shall bear all commodity brokerage fees and commissions and,  except
as otherwise set forth herein or described in the Prospectus, shall be obligated
to  pay all liabilities incurred by  it, including, without limitation, all fees
and expenses incurred in connection with its trading activities (including floor
brokerage fees,  exchange  fees, clearinghouse  fees,  NFA fees,  "give  up"  or
transfer    fees,    costs   associated    with    the   taking    of   delivery
 
                                      A-7
<PAGE>
of futures interests, fees for  the execution of forward contract  transactions,
fees  for the execution of cash transactions relating to the exchange of futures
for physical  transactions, and  the use  of DWR's  institutional and  overnight
execution   facilities  (collectively,  "transaction   fees  and  costs")),  and
management and  incentive  fees payable  to  its trading  advisors.  Appropriate
reserves  may be created, accrued, and charged against Net Assets for contingent
liabilities, if any, as of the date any such contingent liability becomes  known
to  the  General Partner.  Such reserves  shall  reduce the  Net Asset  Value of
interests in the Partnership for all purposes, including redemptions.
 
    The following  special limits  shall  apply to  the Partnership's  fees  and
expenses,  in  accordance with  Section IV.C  of the  NASAA Guidelines:  (a) the
aggregate of (i) the management fees  payable by the Partnership to the  trading
advisors  for the Partnership, and (ii)  the Partnership's customary and routine
administrative expenses (other than commodity brokerage commissions, transaction
fees and  costs, incentive  fees,  legal and  auditing  fees and  expenses,  and
extraordinary  expenses), shall  not exceed 1/2  of 1% of  the Partnership's Net
Assets per  month, or  6% of  the  Partnership's Net  Assets annually;  (b)  the
quarterly  incentive fees payable by the Partnership to any trading advisors for
the Partnership shall not  exceed 15% of the  Partnership's Trading Profits  (as
defined  in the Prospectus), PROVIDED that  such incentive fees may be increased
by 2% for each 1% by which  the aggregate fees and expenses described in  clause
(a) of this sentence are limited below the 6% of Net Assets annual limit thereon
(i.e.,  if such fees and  expenses are limited to 4%  of Net Assets, the maximum
incentive fee payable may  be increased to 19%);  (c) the brokerage  commissions
(excluding  transaction fees and costs) payable by the Partnership to DWR or any
other commodity broker for the Partnership shall not exceed 80% of DWR's or such
other commodity broker's  published non-member rates  for speculative  accounts;
and  (d)  the  aggregate  of  (i)  the  brokerage  commissions  payable  by  the
Partnership to DWR or any other  commodity broker for the Partnership, (ii)  the
transaction  fees and costs payable by the Partnership, and (iii) the net excess
interest and compensating balance benefits to DWR or any other commodity  broker
for the Partnership (after crediting the Partnership with interest, as described
in  Section  7(i) and  the Prospectus),  shall  not exceed  14% annually  of the
Partnership's average monthly Net Assets as of the last day of each month during
each calendar year. The  General Partner or an  affiliate thereof shall pay  and
shall not be reimbursed for any fees and expenses in excess of any such limits.
 
    (F)   LIMITED LIABILITY OF LIMITED PARTNERS.  Each Unit, when purchased by a
Limited Partner in accordance with the  terms of this Agreement, shall be  fully
paid and nonassessable. No Limited Partner shall be liable for the Partnership's
obligations  in  excess  of  such  Partner's  unredeemed  capital  contribution,
undistributed profits, if any, and  any distributions and amounts received  upon
redemption  of Units, together with interest  thereon. The Partnership shall not
make a claim against  a Limited Partner with  respect to amounts distributed  to
such Partner or amounts received by such Partner upon redemption of Units unless
the  Net  Assets  of the  Partnership  (which  shall not  include  any  right of
contribution from the General Partner except to the extent previously made by it
pursuant to this Agreement) shall  be insufficient to discharge the  liabilities
of the Partnership which shall have arisen prior to the payment of such amounts.
 
    (G)  RETURN OF LIMITED PARTNER'S CAPITAL CONTRIBUTION.  Except to the extent
that  a  Limited  Partner  shall  have the  right  to  withdraw  capital through
redemption of Units in accordance with  Section 10(b), no Limited Partner  shall
have  any right to demand the return  of his capital contribution or any profits
added thereto, except upon termination and dissolution of the Partnership. In no
event shall  a  Limited  Partner be  entitled  to  demand or  receive  from  the
Partnership property other than cash.
 
    (H)    DISTRIBUTIONS.   The General  Partner shall  have sole  discretion in
determining what distributions (other than on redemption of Units), if any,  the
Partnership  shall make to its Partners. If made, all distributions shall be pro
rata in accordance with the respective capital accounts of the Partners and  may
be  made by credit to a  Limited Partner's account with DWR  or by check if such
account is closed.
 
    (I)  INTEREST ON ASSETS.   The Partnership shall  deposit all of its  assets
with  DWR and such other commodity brokers as the Partnership shall utilize from
time to time,  and such assets  shall be used  by the Partnership  to engage  in
futures   interests  trading.  Unless  provided  otherwise  in  the  Prospectus,
 
                                      A-8
<PAGE>
such assets will be invested in  securities approved by the CFTC for  investment
of  customer funds or held in non-interest-bearing accounts, and DWR will credit
the  Partnership  at  month-end  with  interest  income  as  set  forth  in  the
Prospectus.
 
8.  MANAGEMENT AND TRADING POLICIES.
 
    (A)  MANAGEMENT OF THE PARTNERSHIP.  Except as may be otherwise specifically
provided  herein, the General Partner, to the exclusion of all Limited Partners,
shall conduct and  manage the  business of the  Partnership, including,  without
limitation,  the investment of the funds  of the Partnership. No Limited Partner
shall have  the power  to represent,  act for,  sign for,  or bind  the  General
Partner  or  the Partnership.  Except as  provided herein,  no Partner  shall be
entitled to any salary, draw, or  other compensation from the Partnership.  Each
Limited  Partner  hereby  undertakes  to furnish  to  the  General  Partner such
additional information  as  may be  determined  by  the General  Partner  to  be
required  or appropriate for the Partnership to  open and maintain an account or
accounts with commodity brokerage  firms for the purpose  of trading in  futures
interests.
 
    The  General Partner shall be under a  fiduciary duty to conduct the affairs
of the  Partnership  in the  best  interests  of the  Partnership.  The  Limited
Partners will under no circumstances be permitted to contract away, or be deemed
to  have contracted  away, the  fiduciary obligations  owed them  by the General
Partner under statutory or common law. The General Partner shall have  fiduciary
responsibility  for  the safekeeping  of  all of  the  funds and  assets  of the
Partnership, whether or  not in  its immediate  possession or  control, and  the
General  Partner shall not  employ, or permit  another to employ,  such funds or
assets in any manner except for the benefit of the Partnership.
 
    In the event that the General Partner at any time believes, upon the  advice
of counsel to the General Partner or as a result of a position taken by the SEC,
that  the Partnership may be required to register as an investment company under
the Investment  Company Act  of 1940,  as  amended (the  "1940 Act"),  then  the
General  Partner  may  terminate  the  Partnership's  futures  interests trading
activity, liquidate  all open  futures interests  and take  such action  as  the
General   Partner  believes  appropriate  to  avoid  the  requirement  that  the
Partnership register as  an investment company  or take all  action the  General
Partner  believes appropriate  or necessary  to register  the Partnership  as an
investment company and bring the Partnership into compliance with the 1940 Act.
 
    (B)  GENERAL PARTNER.   The General Partner,  on behalf of the  Partnership,
shall  retain one or more trading advisors (who may include officers, employees,
and affiliates of the General Partner, DWR, and DWD; PROVIDED, HOWEVER, that  no
such  officer, employee or affiliate shall be retained as trading advisor to the
Partnership until the first business day following a Redemption Date (as defined
in Section 10(b)),  and (i)  notice of  such retention  must be  mailed to  each
Limited  Partner at least five  business days prior to the  last date on which a
"Request for Redemption" (as defined in  Section 10(b)) must be received by  the
General  Partner with respect  to the applicable Redemption  Date; and (ii) such
notice must describe the  redemption and voting rights  of Limited Partners,  as
set  forth  in Sections  10(b) and  15) to  make all  trading decisions  for the
Partnership and  shall  delegate complete  trading  discretion to  such  trading
advisors;  PROVIDED, HOWEVER, that the General  Partner may override any trading
instructions: (i) that the General  Partner, in its sole discretion,  determines
to  be in violation  of any trading policy  of the Partnership,  as set forth in
subsection (c) below; (ii) to the  extent the General Partner believes doing  so
is  necessary  for the  protection of  the Partnership;  (iii) to  terminate the
futures interests trading  of the  Partnership; (iv) to  comply with  applicable
laws  or regulations; or (v) as and to the extent necessary, upon the failure of
a trading advisor to comply with a request to make the necessary amount of funds
available to  the  Partnership  within  five  days  of  such  request,  to  fund
distributions, redemptions, or reapportionments among trading advisors or to pay
the expenses of the Partnership; and PROVIDED, FURTHER, that the General Partner
may  make trading decisions at any time  at which a trading advisor shall become
incapacitated or some  other emergency  shall arise as  a result  of which  such
trading  advisor shall  be unable  or unwilling to  act and  a successor trading
advisor has not yet been retained.
 
                                      A-9
<PAGE>
    The Partnership  shall  not  enter  into  any  agreement  with  DWR  or  its
affiliates  (other than a selling agreement  as contemplated by Section 6) which
has a term of  more than one year  and which does not  provide that it shall  be
terminable by the Partnership without penalty upon 60 days' prior written notice
by  the General Partner; PROVIDED, HOWEVER,  that any such agreement may provide
for  automatic  renewal  for  additional   one-year  terms  unless  either   the
Partnership or DWR or its affiliates, upon written notice given not less than 60
days  prior to the  original termination date or  any extended termination date,
notifies the other party of its intention not to renew.
 
    Subject  to  the  foregoing  paragraph,   the  General  Partner  is   hereby
authorized,  on behalf of the Partnership, to  enter into the form of management
agreement described in the Prospectus (the "Management Agreements") with each of
the trading advisors described in the  Prospectus, and to cause the  Partnership
to  pay to such  persons the management  and incentive fees  provided for in the
Management Agreements, as described in the Prospectus.
 
    The General Partner is further authorized: (a) to modify (including changing
the form  and  amount of  compensation  and  other arrangements  and  terms)  or
terminate any management agreement in its sole discretion in accordance with the
terms  of such agreements and to employ from time to time other trading advisors
for the  Partnership pursuant  to management  agreements having  such terms  and
conditions and providing for such form and amount of compensation as the General
Partner  in its sole  discretion shall deem to  be in the  best interests of the
Partnership, which terms may include provision  for the payment of an  incentive
fee  to a new or replacement trading advisor or advisors which shall be based on
any  trading  profits  which  shall  be  earned  by  such  trading   advisor(s),
irrespective of whether such profits shall exceed trading losses incurred by any
previous  or existing  trading advisor  or advisors or  by the  Partnership as a
whole; (b) to enter into the Customer Agreement described in the Prospectus (the
"Customer  Agreement")  with  DWR,  as  commodity  broker,  and  to  cause   the
Partnership  to pay  to DWR brokerage  commissions and transaction  costs at the
rates provided for in the Customer Agreement and as described in the Prospectus;
and (c) to modify  (including changing the form  and amount of compensation  and
other  arrangements and terms) and terminate  the Customer Agreement in its sole
discretion in accordance  with the terms  of such Agreement  and to employ  from
time  to time other  commodity brokers for the  Partnership pursuant to customer
agreements having such  terms and  conditions and  providing for  such form  and
amount  of compensation as the General Partner in its sole discretion shall deem
to be  in the  best interest  of the  Partnership, PROVIDED,  HOWEVER, that  the
General  Partner shall review at least  annually the brokerage arrangements with
the Partnership to ensure that such brokerage commissions are fair,  reasonable,
and  competitive, and  represent the best  price and  services available, taking
into consideration, in particular, when  the commodity broker is an  "affiliate"
of  the General Partner (as such term is defined in Section 14(c)): (i) the size
of the  Partnership; (ii)  the  futures interests  trading activity;  (iii)  the
services  provided by the commodity broker, the General Partner or any affiliate
thereof to the Partnership; (iv) the cost incurred by the commodity broker,  the
General  Partner  or  any  affiliate thereof  in  organizing  and  operating the
Partnership and offering Units; (v) the  overall costs to the Partnership;  (vi)
any  excess interest and  compensating balance benefits  to the commodity broker
from assets held thereby; and (vii) if the General Partner does not receive  any
direct  compensation from the  Partnership for its  services as General Partner,
the risks incurred by the General Partner as such.
 
    The General  Partner  may subdivide  or  combine Units  in  its  discretion,
provided  that no  such subdivision  or combination  shall affect  the Net Asset
Value of any Limited Partner's interest in the Partnership.
 
    (C)   GENERAL TRADING  POLICIES.   The  General  Partner shall  require  all
trading  advisors retained by the Partnership to follow the trading policies set
forth below. The following trading policies are applicable to the Partnership as
a whole and do not apply to the trading of any individual trading advisor.
 
       1.  The trading advisors will trade only in those futures interests  that
           have  been approved by the  General Partner. The Partnership normally
    will   not    establish    new    positions   in    a    futures    interest
 
                                      A-10
<PAGE>
    for  any one  contract month  or option  if such  additional positions would
    result in a net long or  short position for that futures interest  requiring
    as  margin or  premium more  than 15%  of the  Partnership's Net  Assets. In
    addition, the Partnership  will, except  under extraordinary  circumstances,
    maintain  positions in  futures interests  in at  least two  market segments
    (I.E., agricultural items,  industrial items  (including energies),  metals,
    currencies,  and  financial  instruments  (including  stock,  financial, and
    economic indexes) ) at any one time.
 
       2.  The Partnership will not acquire additional positions in any  futures
           interest  if such additional positions  would result in the aggregate
    net long or short positions for all futures interests requiring as margin or
    premium for all outstanding positions more than 66 2/3% of the Partnership's
    Net Assets. Under certain market conditions,  such as an abrupt increase  in
    margins  required by  an exchange  or its  clearinghouse or  an inability to
    liquidate open positions because of daily price fluctuation limits or  both,
    the Partnership may be required to commit as margin amounts in excess of the
    foregoing  limit.  In such  event, a  trading advisor  will reduce  its open
    positions  to  comply  with  the  foregoing  limit  before  initiating   new
    positions.
 
       3.  The  Partnership will trade  currencies and other  commodities in the
           interbank and  forward contract  markets  only with  banks,  brokers,
    dealers,  and  other financial  institutions which  the General  Partner, in
    conjunction with DWR, has determined to be creditworthy. In determining  the
    creditworthiness  of  a  counterparty  to a  forward  contract,  the General
    Partner and DWR  will consult with  the Corporate Credit  Department of  DWR
    which  monitors participants in the interbank and forward markets with which
    DWR deals on a regular basis.
 
       4.  The trading advisors  will not  generally take a  position after  the
           first notice day in any futures interest during the delivery month of
    that futures interest, except to match trades to close out a position on the
    interbank foreign currency or other forward markets or liquidate trades in a
    limit market.
 
       5.  The  Partnership will not employ the trading technique commonly known
           as "pyramiding," in which the  speculator uses unrealized profits  on
    existing  positions  in  a given  futures  interest due  to  favorable price
    movement as margin specifically to buy  or sell additional positions in  the
    same  or a related  futures interest. Taking  into account the Partnership's
    open trade equity on existing positions in determining generally whether  to
    acquire  additional futures interest positions  on behalf of the Partnership
    will not be considered to constitute "pyramiding."
 
       6.  The Partnership will not purchase, sell, or trade securities  (except
           securities  approved by the  CFTC for investment  of customer funds).
    The Partnership may, however, trade  in futures contracts on securities  and
    securities  indexes, options on such  futures contracts, and other commodity
    options.
 
       7.  The Partnership  will  not  under any  circumstances  lend  money  to
           affiliated  entities or  otherwise. The Partnership  will not utilize
    borrowings  except  if  the  Partnership  purchases  or  takes  delivery  of
    commodities.  If the Partnership  borrows money from  the General Partner or
    any "affiliate" thereof (as defined in the first sentence of Section 14(c)),
    the lending entity in such case  (the "Lender") may not receive interest  in
    excess  of its interest costs, nor may the Lender receive interest in excess
    of the amounts which would be charged the Partnership (without reference  to
    the  General Partner's financial abilities or guarantees) by unrelated banks
    on comparable  loans  for  the same  purpose,  nor  may the  Lender  or  any
    affiliate  thereof receive  any points  or other  financing charges  or fees
    regardless of the amount. Use of lines of credit in connection with  forward
    trading does not, however, constitute borrowing for purposes of this trading
    limitation.
 
       8.  The  Partnership  will  not permit  "churning"  of  the Partnership's
           assets.
 
    (D)  CHANGES TO TRADING  POLICIES.  The General  Partner shall not make  any
material  change in the trading policies in Section 8(c) without obtaining prior
written approval of  Limited Partners owning  more than 50%  of the  outstanding
Units.
 
                                      A-11
<PAGE>
    (E)   MISCELLANEOUS.  The General Partner  may take such other actions as it
deems necessary  or  desirable  to  manage  the  business  of  the  Partnership,
including,  but not limited to, the  following: opening bank accounts and paying
or authorizing the payment of distributions to the Partners and the expenses  of
the  Partnership,  such  as  brokerage  fees  and  commissions,  management  and
incentive fees, and transaction fees and costs.
 
    The General Partner shall prepare or cause to be prepared and shall file  on
or  before the due date (or any  extension thereof) any federal, state, or local
tax returns which shall be required to be filed by the Partnership. The  General
Partner shall cause the Partnership to pay any taxes payable by the Partnership;
PROVIDED,  HOWEVER, that the General Partner shall  not be required to cause the
Partnership to pay any  tax so long  as the General  Partner or the  Partnership
shall  be  in good  faith and  by appropriate  legal proceedings  contesting the
validity, applicability, or amount thereof and such contest shall not materially
endanger any right or interest of the Partnership.
 
    The General Partner  shall be authorized  to perform all  duties imposed  by
Sections  6221 through 6233 of  the Code on the  General Partner as "tax matters
partner" of the Partnership, including, but  not limited to, the following:  (a)
the  power  to  conduct all  audits  and other  administrative  proceedings with
respect to  Partnership  tax items;  (b)  the power  to  extend the  statute  of
limitations  for all Limited Partners with respect to Partnership tax items; (c)
the power to file a petition with  an appropriate federal court for review of  a
final  Partnership administrative adjustment; and (d)  the power to enter into a
settlement with the  Internal Revenue Service  on behalf of,  and binding  upon,
those Limited Partners having less than a 1% interest in the Partnership, unless
a  Limited  Partner shall  have notified  the Internal  Revenue Service  and the
General Partner that the General Partner may not act on such Partner's behalf.
 
    If the Partnership  is required to  withhold United States  taxes on  income
with  respect  to  Units held  by  Limited  Partners who  are  nonresident alien
individuals, foreign  corporations,  foreign partnerships,  foreign  trusts,  or
foreign  estates, the General Partner may pay such  tax out of its own funds and
then be reimbursed out  of the proceeds of  any distribution or redemption  with
respect to such Units.
 
    The  General Partner shall  keep at the principal  office of the Partnership
such books and records relating to the  business of the Partnership as it  deems
necessary  or  advisable, as  are  required by  the  Commodity Exchange  Act, as
amended (the "CEAct"), and  the CFTC's rules and  regulations thereunder, or  as
shall be required by other regulatory bodies, exchanges, boards, and authorities
having jurisdiction. Such books and records shall be retained by the Partnership
for not less than five years.
 
    The  Partnership's books and records shall  be available to Limited Partners
or their authorized attorneys or agents for inspection and copying during normal
business hours of the Partnership and,  upon request, the General Partner  shall
send  copies of same  to any Limited  Partner upon payment  by him of reasonable
reproduction and distribution costs. Any subscription documentation executed  by
a  Limited Partner in connection with his purchase of Units shall be retained by
the Partnership for not less than six years.
 
    Except as described  herein or  in the  Prospectus, no  person may  receive,
directly   or  indirectly,  any  advisory,  management,  or  incentive  fee  for
investment advice who shares  or participates in  per trade commodity  brokerage
commissions paid by the Partnership. No commodity broker for the Partnership may
pay, directly or indirectly, rebates or "give-ups" to the General Partner or any
trading advisor, and such prohibitions may not be circumvented by any reciprocal
business  arrangements. Assets of  the Partnership shall  not be commingled with
assets of  any other  person. Margin  deposits  and deposits  of assets  with  a
commodity broker shall not constitute commingling.
 
    The   General  Partner  shall   devote  such  time   and  resources  to  the
Partnership's business  and affairs  as it  in its  sole discretion  shall  deem
necessary or advisable to effectively manage the Partnership. Subject to Section
5,  the General Partner may engage in other business activities and shall not be
required to refrain  from any other  activity or disgorge  any profits from  any
such  activity, whether as general partner of additional partnerships formed for
investment in futures interests or otherwise. The
 
                                      A-12
<PAGE>
General Partner  may engage  and compensate,  on behalf  and from  funds of  the
Partnership,  such  persons, firms,  or  corporations, including  any affiliated
person or  entity,  as the  General  Partner in  its  sole judgment  shall  deem
advisable  for the  conduct and  operation of  the business  of the Partnership;
PROVIDED, HOWEVER, that, except as described  herein and in the Prospectus,  the
General  Partner shall not engage  any person, firm, or  corporation which is an
affiliate (as defined  in the first  sentence of Section  14(c)) of the  General
Partner to perform services for the Partnership without having made a good faith
determination  that: (i)  the affiliate which  it proposes to  engage to perform
such services is  qualified to do  so (considering the  prior experience of  the
affiliate or the individuals employed thereby); (ii) the terms and conditions of
the  agreement pursuant to which  such affiliate is to  perform services for the
Partnership are no less favorable to the Partnership than could be obtained from
equally-qualified unaffiliated third parties, or are otherwise determined by the
General Partner to  be fair and  reasonable to the  Partnership and the  Limited
Partners;  and (iii)  the maximum  period covered  by the  agreement pursuant to
which such affiliate is to perform services for the Partnership shall not exceed
one year, and such agreement shall  be terminable without penalty upon 60  days'
prior  written notice  by the  Partnership. Nothing  contained in  the preceding
sentence shall prohibit  the General Partner  from receiving reimbursement  from
the  Partnership for expenses advanced on  behalf of the Partnership (other than
organizational and offering expenses).
 
    No person dealing with  the General Partner shall  be required to  determine
its  authority  to make  any  undertaking on  behalf  of the  Partnership  or to
determine any fact or circumstance bearing upon the existence of its authority.
 
9.  AUDITS; REPORTS TO LIMITED PARTNERS.
 
    The  Partnership's  books  shall  be  audited  annually  by  an  independent
certified  public accounting  firm selected by  the General Partner  in its sole
discretion. The Partnership shall cause each  Partner to receive: (a) within  90
days  after the close  of each fiscal  year an annual  report containing audited
financial statements  (including  a  statement  of income  and  a  statement  of
financial condition) of the Partnership for the fiscal year then ended, prepared
in accordance with generally accepted accounting principles and accompanied by a
report  of the certified  public accounting firm  which audited such statements,
and such other information  as the CFTC  and NFA may from  time to time  require
(such  annual reports will provide a detailed statement of any transactions with
the General  Partner  or  its  affiliates  and  of  fees,  commissions  and  any
compensation  paid or accrued to  the General Partner or  its affiliates for the
fiscal year completed, showing the amount paid or accrued to each recipient  and
the  services performed); (b) within 75 days after the close of each fiscal year
(but in no event later than March 15 of each year) such tax information relating
to the Partnership  as is  necessary for such  Partner to  complete his  federal
income  tax return; (c)  within 30 days  after the close  of each calendar month
such financial and other information with respect to the Partnership as the CFTC
and NFA  from time  to time  shall  require in  monthly reports,  together  with
information concerning any material change in the brokerage commissions and fees
payable  by the Partnership to DWR; and (d)  at such times as shall be necessary
or advisable in the General Partner's sole discretion, such other information as
the CFTC and NFA from time to time shall require under the CEAct to be given  to
participants in commodity pools.
 
    In  addition, if any of  the following events occurs,  notice of such event,
including a description of the redemption and voting rights of Limited Partners,
as set forth in Sections 10(b) and  15, shall be mailed to each Limited  Partner
within seven business days after the occurrence of such event: (a) a decrease in
the Net Asset Value of a Unit as of the close of business on any business day to
50%  or  less  of the  Net  Asset Value  for  such Unit  as  of the  end  of the
immediately preceding month; (b) any  material amendment to this Agreement;  (c)
any  change  in  trading  advisors  or any  material  change  in  the management
agreement with a  trading advisor; (d)  any change in  commodity brokers or  any
material  change in the  compensation arrangements with  a commodity broker; (e)
any change  in general  partners  or any  material  change in  the  compensation
arrangements  with a general partner; (f) any change in the Partnership's fiscal
year; (g) any  material change  in the  Partnership's trading  policies; or  (h)
cessation  of futures  interests trading  by the Partnership.  In the  case of a
notice given  in  accordance  with  clause  (a)  of  the  immediately  preceding
sentence:  (i) such  notice shall also  advise Limited Partners  that a "Special
 
                                      A-13
<PAGE>
Redemption Date," on a date  specified in such notice  (but in no event  earlier
than  15, nor later than  45, days after the mailing  of such notice), will take
place as of which Limited Partners may redeem their Units in the same manner  as
provided  in Section  10(b) for regular  Redemption Dates  (a Special Redemption
Date may take place on a regular Redemption Date); and (ii) following the  close
of  business on  the date of  the 50% decrease  giving rise to  such notice, the
Partnership shall liquidate  all existing  positions as  promptly as  reasonably
practicable  and shall suspend all futures interests trading through the Special
Redemption Date.  Thereafter, the  General Partner  shall determine  whether  to
reinstitute  futures interests trading or to  terminate the Partnership. As used
herein, "material change in the  Partnership's trading policies" shall mean  any
change in those trading policies specified in Section 8(c).
 
    The  Net Asset  Value of  a Unit  shall be  determined daily  by the General
Partner, and  the most  recent Net  Asset Value  calculation shall  be  promptly
supplied  by the  General Partner  in writing to  any Limited  Partner after the
General Partner shall have received a written request from such Partner.
 
    In addition, no increase (subject to  the limits in the fourth paragraph  of
Section  7(e))  in  any of  the  management  or incentive  fees  payable  by the
Partnership, or the caps on  brokerage commissions, transaction fees and  costs,
ordinary administrative expenses, or net excess interest or compensating balance
benefits,  all as described in  the Prospectus, may take  effect until the first
business day following a Redemption Date (as defined in Section 10(b)), PROVIDED
that: (i) notice of  such increase is  mailed to each  Limited Partner at  least
five  business days prior to  the last date on  which a "Request for Redemption"
(as defined  in Section  10(b)) must  be received  by the  General Partner  with
respect  to the applicable Redemption Date;  (ii) such notice shall describe the
redemption and voting rights of Limited Partners, as set forth in Sections 10(b)
and 15; and (iii)  none of such fees  or caps may be  increased until the  first
business day following the first Redemption Date as of which a redemption charge
is no longer payable as set forth in Section 10(b).
 
10.  TRANSFER; REDEMPTION OF UNITS.
 
    (A)   TRANSFER.  A Limited Partner may  transfer or assign his Units only as
provided in  this  Section 10(a).  No  transferee  or assignee  shall  become  a
substituted  Limited Partner unless  the General Partner  first consents to such
transfer or  assignment  in  writing,  which consent  the  General  Partner  may
withhold  in its sole discretion.  Any transfer or assignment  of Units which is
permitted hereunder shall be effective as of the end of the month in which  such
transfer or assignment is made; PROVIDED, HOWEVER, that the Partnership need not
recognize  any transfer or  assignment until it  has received at  least 30 days'
prior written notice thereof  from the Limited Partner,  which notice shall  set
forth  the address and social security  or taxpayer identification number of the
transferee or assignee and  the number of Units  to be transferred or  assigned,
and  which notice  shall be  signed by  the Limited  Partner (and  his signature
guaranteed by a commercial bank with a correspondent in New York, New York or by
a  member  of  a  registered  national  securities  exchange).  No  transfer  or
assignment  of Units will be  effective or recognized by  the Partnership if the
transferee or assignee, or the transferor  or assignor (if fewer than all  Units
held by the transferor or assignor are being transferred or assigned), would, by
reason  of such  transfer or  assignment, acquire  Units which  do not  meet the
minimum initial  subscription  requirements,  as described  in  the  Prospectus;
PROVIDED,  HOWEVER, that the foregoing restriction  shall not apply to transfers
or assignments of  Units (i)  by the  way of gift  or inheritance,  (ii) to  any
members   of  the  Limited  Partner's  family,  (iii)  resulting  from  divorce,
annulment, separation or similar proceedings, or (iv) to any person who would be
deemed an "affiliate" of the Limited Partner as defined in the first sentence of
Section 14(c) [adding  new clause  (v) as  follows: "(v)  if such  person is  an
officer,  director  or partner,  any  partnership, corporation,  association, or
other legal  entity  for which  such  person acts  in  any such  capacity"].  No
transfer  or  assignment  shall  be  permitted  unless  the  General  Partner is
satisfied that (i) such transfer or assignment would not be in violation of  the
Act  or  applicable  federal,  state,  or  foreign  securities  laws,  and  (ii)
notwithstanding such transfer or assignment,  the Partnership shall continue  to
be  classified  as a  partnership rather  than  as an  association taxable  as a
corporation under  the  Code.  No  transfer or  assignment  of  Units  shall  be
effective  or recognized by the Partnership if such transfer or assignment would
result in the termination of the Partnership for federal
 
                                      A-14
<PAGE>
income tax  purposes, and  any  attempted transfer  or assignment  in  violation
hereof shall be ineffective to transfer or assign any such Units. Any transferee
or  assignee  of  Units  who has  not  been  admitted to  the  Partnership  as a
substituted Limited  Partner shall  not have  any  of the  rights of  a  Limited
Partner,  except  that  such person  shall  receive  that share  of  capital and
profits, shall have  that right  of redemption, and  those rights  to which  his
transferor  or  assignor would  otherwise have  been  entitled and  shall remain
subject to the other terms of  this Agreement binding upon Limited Partners.  No
Limited  Partner  shall have  any  right to  approve  of any  person  becoming a
substituted Limited Partner. The Limited Partner shall bear all costs (including
any attorneys' and accountants' fees) related to such transfer or assignment  of
his Units.
 
    In  the  event that  the  General Partner  consents  to the  admission  of a
substituted Limited Partner pursuant to this Section 10(a), the General  Partner
is  hereby authorized to take  such actions as may  be necessary to reflect such
substitution of a Limited Partner.
 
    (B)  REDEMPTION.  Except as set forth below and in accordance with the terms
hereof, a Limited Partner (or any assignee thereof) may withdraw all or part  of
his  unredeemed  capital  contribution  and undistributed  profits,  if  any, by
requiring the Partnership to redeem  all or part of his  Units at the Net  Asset
Value  thereof, reduced as  hereinafter described (any  such withdrawal shall be
referred to herein as a "Redemption").  Redemptions shall be made only in  whole
Units  or in multiples of $1,000, except that fractions of Units may be redeemed
if a Limited Partner shall be redeeming his entire interest in the Partnership.
 
    Units may be  redeemed at the  option of a  Limited Partner as  of, but  not
before,  the sixth month-end following the  closing at which the Limited Partner
first becomes a Limited Partner. Thereafter, Units may be redeemed as of the end
of any month. However, any Units redeemed at or prior to the end of the twelfth,
eighteenth or twenty-fourth full month following the closing at which such Units
are issued  will  be assessed  a  redemption charge  equal  to 3%,  2%,  or  1%,
respectively  of the Net Asset  Value of a Unit on  the date of such redemption.
The foregoing charges will be paid to DWR. A limited partner in any of the other
commodity pools for which the General Partner serves as the general partner  and
who  purchases Units pursuant to an Exchange (as defined in the Prospectus) will
not be subject  to the foregoing  redemption charges or  restrictions under  the
circumstances  described below. The number of Units (determined on a per closing
basis), expressed as a percentage of Units purchased, which are not subject to a
redemption charge is determined by dividing (a) the dollar amount received  upon
redeeming  an interest in such  other partnership and used  to purchase Units by
(b) the total investment in the Partnership. In addition, redemption charges may
not be  imposed  for certain  large  purchasers of  Units,  as provided  in  the
Prospectus. Redemptions of Units will be deemed to be in the order in which they
are  purchased (assuming purchases at more than one closing), with the Units not
subject to a redemption charge being deemed to be the first Units purchased at a
closing.
 
    Redemption of a Limited  Partner's Units shall be  effective as of the  last
day  of the first  month ending after  an irrevocable Request  for Redemption in
proper form shall have been received by the General Partner ("Redemption Date");
PROVIDED, that  all liabilities,  contingent or  otherwise, of  the  Partnership
(except  any liability  to Partners on  account of  their capital contributions)
shall have  been  paid  or  there  shall  remain  property  of  the  Partnership
sufficient  to pay them. As  used herein, "Request for  Redemption" shall mean a
letter in the form specified by the General Partner and received by the  General
Partner  by 5:00 p.m. (New York City time)  at least five business days prior to
the date on  which such Redemption  is to be  effective. A form  of Request  for
Redemption  is  annexed  to  this Agreement.  Additional  forms  of  Request for
Redemption may be obtained by written request to the General Partner.
 
    Upon Redemption, a Limited Partner  (or any assignee thereof) shall  receive
from  the Partnership for  each Unit redeemed  an amount equal  to the Net Asset
Value thereof (as defined  in Section 7(d)(2)) as  of the Redemption Date,  less
any  redemption charges and any amount owing  by such Partner (and his assignee,
if any)  to  the Partnership  pursuant  to Section  14(d).  If a  Redemption  is
requested  by an  assignee, all  amounts owed  to the  Partnership under Section
14(d) by the Partner to whom such Unit was sold, as well as all amounts owed  by
all    assignees   of   such   Unit,   shall    be   deducted   from   the   Net
 
                                      A-15
<PAGE>
Asset Value of such Unit upon Redemption. The General Partner shall endeavor  to
pay  Redemptions within 10 business days  after the Redemption Date, except that
under special circumstances (including, but not limited to, the inability on the
part of the Partnership to liquidate futures interests positions or the  default
or  delay in payments which shall be due the Partnership from commodity brokers,
banks, or  other  persons),  the  Partnership  may  delay  payment  to  Partners
requesting  Redemption of Units of the proportionate part of the Net Asset Value
of the Units represented by  the sums which are the  subject of such default  or
delay.  Redemptions will  be made  by credit  to the  Limited Partner's customer
account with DWR or by  check mailed to the Limited  Partner if such account  is
closed.  The  General  Partner  may,  in  its  absolute  discretion,  waive  any
restrictions or charges applicable to redemptions.
 
    The foregoing terms and conditions in  this Section 10(b), other than  those
in  the  second  paragraph  hereof  prohibiting  redemptions  before  the  sixth
month-end following  the closing  at  which a  person  first becomes  a  Limited
Partner,  shall also apply to redemptions effected on "Special Redemption Dates"
held in accordance with Section 9.
 
    The General  Partner  shall be  authorized  to execute,  file,  record,  and
publish,  on behalf of the Partnership and each Partner, such amendments to this
Agreement and such other documents as shall be necessary or desirable to reflect
any Redemption pursuant to this Section 10(b).
 
11.  SPECIAL POWER OF ATTORNEY.
 
    Each Limited Partner, by the  execution of this Agreement, does  irrevocably
constitute  and appoint the General Partner, with full power of substitution, as
his true and lawful agent and  attorney-in-fact, in his name, place, and  stead,
(a)  to execute, acknowledge, swear to, deliver,  file, and record in his behalf
in the  appropriate public  offices, and  publish: (i)  this Agreement  and  the
Certificate  of Limited Partnership and amendments thereto; (ii) all instruments
that  the  General  Partner  deems  necessary  or  appropriate  to  reflect  any
amendment,  change,  or modification  of this  Agreement  or the  Certificate of
Limited Partnership made in accordance with  the terms of this Agreement;  (iii)
certificates  of assumed name; and (iv) all instruments that the General Partner
deems necessary or appropriate to qualify  or maintain the qualification of  the
Partnership   to  do  business  as  a   foreign  limited  partnership  in  other
jurisdictions; and (b) to admit additional  Limited Partners and, to the  extent
that it is necessary under the laws of any jurisdiction, to execute, deliver and
file  amended  certificates  or  agreements  of  limited  partnership  or  other
instruments to  reflect such  admission. The  Power of  Attorney granted  herein
shall be irrevocable and deemed to be a power coupled with an interest and shall
survive  the incapacity,  death, dissolution,  liquidation, or  termination of a
Limited Partner.  Each  Limited  Partner  hereby  agrees  to  be  bound  by  any
representation  made by the General Partner  and by any successor thereto acting
in good faith pursuant to such Power of Attorney. Each Limited Partner agrees to
execute a special Power of Attorney on a document separate from this  Agreement.
In the event of any conflict between this Agreement and any instruments filed by
such  attorney-in-fact pursuant to the Power of Attorney granted in this Section
11, this Agreement shall control.
 
12.  WITHDRAWAL OF PARTNERS.
 
    The Partnership  shall  terminate  and be  dissolved  upon  the  withdrawal,
insolvency,  bankruptcy, dissolution, liquidation, or termination of the General
Partner (unless a new general partner  is elected pursuant to Section 15(c)  and
such  remaining general partner  shall have elected to  continue the business of
the Partnership, which  any remaining general  partner shall have  the right  to
do).  The General Partner shall  not withdraw or assign  all of its interests at
any time without giving the Limited  Partners 120 days' prior written notice  of
its intention to withdraw or assign and, if the Limited Partners thereupon elect
a  new general  partner or  partners pursuant  to Section  15(c) which  elect to
continue the business of the Partnership, the withdrawing General Partner  shall
pay  all reasonable expenses incurred by the Partnership in connection with such
withdrawal. The  General  Partner shall  be  paid the  Net  Asset Value  of  its
interests in the Partnership as of the date of such withdrawal.
 
    The  death, incompetency,  withdrawal, insolvency,  bankruptcy, termination,
liquidation, or dissolution of a Limited Partner shall not terminate or dissolve
the Partnership, and such  Limited Partner, his  estate, custodian, or  personal
representative   shall  have  no  right  to   withdraw  or  value  such  Limited
 
                                      A-16
<PAGE>
Partner's interest in  the Partnership except  as provided in  Section 10.  Each
Limited  Partner (and any assignee of  such Partner's interest) expressly agrees
that in the event of  his death, he waives on  behalf of himself and his  estate
and  he directs the legal representative of his estate and any person interested
therein to waive the  furnishing of any inventory,  accounting, or appraisal  of
the  assets of the Partnership  and any right to an  audit or examination of the
books of the Partnership.
 
13.  NO PERSONAL LIABILITY FOR RETURN OF CAPITAL.
 
    Subject to Section 14, neither the General Partner, DWR, nor any "affiliate"
(as defined in Section 14(c)) thereof shall be personally liable for the  return
or  repayment of all or any portion of the capital or profits of any Partner (or
assignee), it being expressly agreed that any such return of capital or  profits
made  pursuant to  this Agreement  shall be made  solely from  the assets (which
shall not include  any right of  contribution from the  General Partner) of  the
Partnership.
 
14.  STANDARD OF LIABILITY; INDEMNIFICATION.
 
    (A)   STANDARD OF LIABILITY.   The General Partner  and its "affiliates" (as
defined in Section 14(c))  shall not be liable  to the Partnership, the  Limited
Partners,  or its or their successors or assigns, for any act, omission, conduct
or activity undertaken  by or  on behalf of  the Partnership  which the  General
Partner  determines,  in  good  faith,  to  be  in  the  best  interests  of the
Partnership,  unless  such  act,  omission,  conduct,  or  activity  constituted
misconduct or negligence.
 
    (B)   INDEMNIFICATION BY THE PARTNERSHIP.   The Partnership shall indemnify,
defend, and hold harmless the General  Partner and its "affiliates" (as  defined
in Section 14(c)) from and against any loss, liability, damage, cost, or expense
(including  attorneys' and accountants' fees and expenses incurred in defense of
any demands, claims, or lawsuits) actually and reasonably incurred arising  from
any  act,  omission, activity,  or conduct  undertaken  by or  on behalf  of the
Partnership, including,  without limitation,  any demands,  claims, or  lawsuits
initiated  by a  Limited Partner  (or assignee  thereof), PROVIDED  that (1) the
General Partner has determined, in good  faith, that the act, omission,  conduct
or  activity  giving rise  to  the claim  for  indemnification was  in  the best
interests of the Partnership,  and (2) the act,  omission, activity, or  conduct
that  was the basis for  such loss, liability, damage,  cost, or expense was not
the result of misconduct or negligence. Notwithstanding anything to the contrary
contained in  the  foregoing,  neither  the  General  Partner  nor  any  of  its
affiliates  nor any person acting as a broker-dealer shall be indemnified by the
Partnership for any losses,  liabilities or expenses arising  from or out of  an
alleged  violation of federal or state securities laws unless (1) there has been
a successful  adjudication  on  the  merits  of  each  count  involving  alleged
securities  law violations as  to the particular indemnitee,  or (2) such claims
have been  dismissed  with prejudice  on  the merits  by  a court  of  competent
jurisdiction  as  to the  particular  indemnitee, or  (3)  a court  of competent
jurisidiction approves  a  settlement  of  the  claims  against  the  particular
indemnitee  and finds that  indemnification of the  settlement and related costs
should be made,  PROVIDED, with regard  to such court  approval, the  indemnitee
must  apprise the  court of the  position of the  SEC, and the  positions of the
respective  securities  administrators  of  Massachusetts,  Missouri,  Tennessee
and/or  those other states and jurisdictions  in which the plaintiffs claim that
they were offered or sold Units, with respect to indemnification for  securities
laws  violations before seeking court approval for indemnification. Furthermore,
in any action or  proceeding brought by  a Limited Partner in  the right of  the
Partnership  to which the  General Partner or  any affiliate thereof  is a party
defendant, any such person shall be  indemnified only to the extent and  subject
to  the conditions specified in the Act  and this Section 14(b). The Partnership
shall make advances to the General Partner or its affiliates hereunder only  if:
(1)  the demand, claim, lawsuit,  or legal action relates  to the performance of
duties or services by such persons  to the Partnership; (2) such demand,  claim,
lawsuit,  or legal action  is not initiated  by a Limited  Partner; and (3) such
advances are repaid, with interest at the legal rate under Delaware law, if  the
person  receiving  such  advance  is  ultimately found  not  to  be  entitled to
indemnification hereunder.
 
    Nothing contained in this Section 14(b) shall increase the liability of  any
Limited  Partner to the Partnership beyond  the amount of his unredeemed capital
contribution, undistributed  profits,  if  any,  and  any  amounts  received  on
distributions  and  redemptions,  together  with  interest  thereon.  All rights
 
                                      A-17
<PAGE>
to indemnification and payment of attorneys' and accountants' fees and  expenses
shall  not be affected by the termination  of the Partnership or the withdrawal,
insolvency, or dissolution of the General Partner.
 
    The Partnership  shall not  incur  the cost  of  that portion  of  liability
insurance which insures the General Partner and its affiliates for any liability
as  to which the  General Partner and  its affiliates are  prohibited from being
indemnified.
 
    (C)  AFFILIATE.  As used in this Agreement, the term "affiliate" of a person
shall mean: (i)  any natural person,  partnership, corporation, association,  or
other  legal entity directly or indirectly  owning, controlling, or holding with
power to vote 10% or more of  the outstanding voting securities of such  person;
(ii)  any partnership,  corporation, association, or  other legal  entity 10% or
more of whose outstanding  voting securities are  directly or indirectly  owned,
controlled, or held with power to vote by such person; (iii) any natural person,
partnership,  corporation,  association,  or  other  legal  entity  directly  or
indirectly controlling,  controlled  by,  or under  common  control  with,  such
person; or (iv) any officer, director or partner of such person. Notwithstanding
the  foregoing, "affiliates" for purposes of  this Section 14 shall include only
those persons performing services for the Partnership.
 
    (D)  INDEMNIFICATION BY PARTNERS.  In the event that the Partnership is made
a party to  any claim, demand,  dispute, or litigation  or otherwise incurs  any
loss, liability, damage, cost, or expense as a result of, or in connection with,
any  Partner's  (or  assignee's)  obligations or  liabilities  unrelated  to the
Partnership's  business,  such   Partner  (or   assignees  cumulatively)   shall
indemnify,  defend, hold harmless, and reimburse  the Partnership for such loss,

the  term of  the Partnership,  the General Partner  shall deem  it necessary or
desirable to amend  this Agreement, such  amendment shall be  effective only  if
embodied  in  an  instrument approved  by  the  General Partner  and  by Limited
Partners owning more  than 50%  of the  Units then  outstanding and  if made  in
accordance  with, and to the extent permissible under, the Act. Any amendment to
this Agreement or actions taken pursuant to this Section 15 that shall have been
approved by the percentage of outstanding Units prescribed above shall be deemed
to have been approved  by all Limited  Partners. Notwithstanding the  foregoing,
the  General Partner  shall be  authorized to  amend this  Agreement without the
consent of  any  Limited  Partner in  order  to:  (i) change  the  name  of  the
Partnership,  (ii) clarify  any inaccuracy  or any  ambiguity, or  reconcile any
inconsistent provisions  herein, (iii)  make any  amendment to  this  Agreement,
PROVIDED that such amendment is not adverse to the Limited Partners, (iv) effect
the  intent of the allocations proposed herein to the maximum extent possible in
the event of a change in the Code or the interpretations thereof affecting  such
allocations,  (v) attempt  to ensure  that the  Partnership is  not taxed  as an
association taxable  as a  corporation  for federal  income tax  purposes,  (vi)
qualify   or  maintain  the  qualification  of  the  Partnership  as  a  limited
partnership in any jurisdiction, (vii) delete or add any provision of or to this
Agreement required to be deleted or added by the staff of the SEC, the CFTC, any
other federal agency or any state "Blue Sky" official or similar official or  in
order  to opt to  be governed by  any amendment or  successor to the  Act, or to
comply with applicable law,  (viii) make any modification  to this Agreement  to
reflect  the  admission  of additional  or  substitute general  partners  and to
reflect any modification to the Net Worth requirements applicable to the General
Partner and any other general partner, as contemplated by Section 5 hereof, (ix)
make any  amendment that  is appropriate  or necessary,  in the  opinion of  the
General  Partner,  to prevent  the  Partnership or  the  General Partner  or its
directors, officers or controlling persons from  in any manner being subject  to
the  provisions of the 1940 Act, the Investment Advisers Act of 1940, as amended
(the "Advisers Act"),  or "plan  asset" regulations adopted  under the  Employee
Retirement  Income  Security  Act of  1974,  as  amended, and  (x)  to  make any
amendment that  is appropriate  or  necessary, in  the  opinion of  the  General
Partner,  to qualify  the Partnership  under the  1940 Act,  and any individuals

                                      A-18
<PAGE>
General Partner is informed that doing so is necessary. Any such supplemental or
amendatory agreement shall be adhered to and have the same force and effect from
and after its effective date as if the same had originally been embodied in, and
formed a part of, this Agreement;  PROVIDED, HOWEVER, that no such  supplemental
or  amendatory agreement  shall, without  the consent  of all  Partners affected
thereby, change or  alter the  provisions of  this proviso,  reduce the  capital
account  of  any  Partner,  or  modify the  percentage  of  profits,  losses, or
distributions to which any Partner is entitled.
 
    (B)  MEETINGS.   Any Limited  Partner or his  authorized attorney or  agent,
upon  written request to the  General Partner, delivered either  in person or by
certified mail, and upon  payment of reasonable  duplicating and postage  costs,
shall be entitled to obtain from the General Partner by mail a list of the names
and addresses of record of all Limited Partners and the number of Units owned by
each.
 
    Upon  receipt of  a written  request, signed  by Limited  Partners owning at
least 10% of the  Units then owned  by Limited Partners, that  a meeting of  the
Partnership  be called to vote  upon any matter upon  which all Limited Partners
may vote pursuant to this Agreement,  the General Partner, by written notice  to
each  Limited Partner of  record sent by  certified mail or  delivered in person
within 15 days after such receipt, shall call a meeting of the Partnership. Such
meeting shall be held at least 30 but not more than 60 days after the mailing of
such notice, and  such notice  shall specify the  date, a  reasonable place  and
time, and the purpose of such meeting.
 
    (C)   AMENDMENTS AND ACTIONS WITHOUT CONSENT OF THE GENERAL PARTNER.  At any
meeting of the  Limited Partners,  upon the affirmative  vote (which  may be  in
person  or by proxy) of Limited Partners owning  more than 50% of the Units then
owned by  Limited Partners,  the  following actions  may  be taken  without  the
consent of the General Partner: (i) this Partnership Agreement may be amended in
accordance  with, and only  to the extent permissible  under, the Act; PROVIDED,
HOWEVER, that  no such  amendment shall,  without the  consent of  all  Partners
affected  thereby, change  or alter the  provisions of this  proviso, reduce the
capital account of any Partner, or modify the percentage of profits, losses,  or
distributions  to which  any Partner  is entitled;  (ii) the  Partnership may be
dissolved; (iii) the  General Partner may  be removed and  replaced; (iv) a  new
general  partner  or general  partners  may be  elected  if the  General Partner
terminates or liquidates or elects to withdraw from the Partnership pursuant  to
Section  12, or becomes insolvent, bankrupt,  or is dissolved; (v) any contracts
with the General  Partner or  any of  its affiliates  (as defined  in the  first
sentence of Section 14(c)) may be terminated without penalty on not less than 60
days' prior written notice; and (vi) the sale of all or substantially all of the
assets  of  the Partnership  may be  approved; PROVIDED,  HOWEVER, that  no such
action shall adversely  affect the  status of  the Limited  Partners as  limited
partners under the Act or the classification of the Partnership as a partnership
under the federal income tax laws; and PROVIDED FURTHER, that Units owned by the
General  Partner and any  affiliate thereof (as defined  in Section 14(c)) shall
not be voted on the matters described in clauses (iii) and (v) above. Any action
which shall have been approved by the percentage of outstanding Units prescribed
above shall be deemed to have been approved by all Limited Partners.
 
    (D)  ACTION WITHOUT  MEETING.  Notwithstanding  contrary provisions of  this
Section 15 covering notices to, meetings of, and voting by Limited Partners, any
action  required or permitted  to be taken  by Limited Partners  at a meeting or
otherwise may be  taken by  Limited Partners  without a  meeting, without  prior
notice,  and without a vote if a consent  in writing setting forth the action so
taken shall be signed by Limited Partners owning Units having not fewer than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting of Limited Partners at which all outstanding Units shall have  been
present  and voted. Notice of the taking of action by Limited Partners without a
meeting by less  than unanimous  written consent  of Limited  Partners shall  be
given  to those Limited Partners who shall  not have consented in writing within
seven business days after the occurrence thereof.
 
                                      A-19
<PAGE>
    (E)  AMENDMENTS TO CERTIFICATE OF  LIMITED PARTNERSHIP.  If an amendment  to
this  Agreement shall be made  pursuant to this Section  15, the General Partner
shall be authorized to  execute, acknowledge, swear  to, deliver, file,  record,
and  publish, on behalf of the Partnership  and each Partner, such amendments to
the Certificate of  Limited Partnership as  shall be necessary  or desirable  to
reflect such amendment.
 
16.  ADDITIONAL OFFERINGS.
 
    The  General  Partner  may, in  its  discretion, make  additional  public or
private offerings of Units, PROVIDED, that  the net proceeds to the  Partnership
of  any such sales shall in no event be  less than the Net Asset Value of a Unit
at the time of sale, and PROVIDED  FURTHER, that such proceeds may be less  than
said  Net Asset Value per Unit if  the newly offered Units' participation in the
Partnership's profits  and losses  is  proportionately reduced.  Any  additional
offering of Units shall be effected in the manner contemplated in Section 6. The
Partnership  shall  not  pay the  costs  of  any such  offering  or  any selling
commissions relating  thereto. No  Limited Partner  shall have  any  preemptive,
preferential  or  other rights  with  respect to  the  issuance or  sale  of any
additional Units, except as described  in the applicable Prospectus. No  Limited
Partner  shall have  the right  to consent  to the  admission of  any additional
Limited Partner. The Partnership may offer  different classes of Units for  sale
having  different economic terms  than the Units previously  sold to the public,
provided that  the issuance  of such  new class  of Units  shall in  no  respect
adversely affect the holders of outstanding Units. There is no maximum aggregate
amount of contributions which may be received by the Partnership.
 
17.  GOVERNING LAW.
 
    THE  VALIDITY AND CONSTRUCTION  OF THIS AGREEMENT SHALL  BE GOVERNED BY, AND
CONSTRUED IN  ACCORDANCE WITH,  THE LAW  OF THE  STATE OF  DELAWARE,  INCLUDING,
SPECIFICALLY,  THE  ACT  (WITHOUT  REGARD  TO  ITS  CHOICE  OF  LAW PRINCIPLES);
PROVIDED, HOWEVER, THAT  CAUSES OF  ACTION FOR  VIOLATIONS OF  FEDERAL OR  STATE
SECURITIES LAWS SHALL NOT BE GOVERNED BY THIS SECTION 17.
 
18.  MISCELLANEOUS.
 
    (A)   PRIORITY AMONG LIMITED PARTNERS.  Except as otherwise specifically set
forth in this Agreement, no Limited Partner shall be entitled to any priority or
preference over  any other  Limited Partner  in  regard to  the affairs  of  the
Partnership.
 
    (B)   NOTICES.   All notices under  this Agreement (other  than Requests for
Redemption, notices  of assignment  or transfer  of Units,  and reports  by  the
General  Partner  to the  Limited Partners)  shall  be in  writing and  shall be
effective upon personal delivery  or, if sent by  registered or certified  mail,
postage  prepaid, addressed to the last known  address of the party to whom such
notice is to  be given, upon  the deposit of  such notice in  the United  States

address of the General Partner or the Limited Partner, as the case may be.
 
    (C)  BINDING EFFECT.  This Agreement  shall inure to the benefit of, and  be
binding upon, all of the parties, their successors, assigns as permitted herein,

that they may have under Section 15.

- --------------------------------------------------------------------------------
REPRESENTATIONS AND WARRANTIES
- --------------------------------------------------------------------------------
 
    Subscriber (for myself/ourselves, and, if Subscriber is an entity, on behalf
of  and  with  respect  to  such  entity  and  its  shareholders,  partners,  or
beneficiaries)  hereby represents  and warrants to  the General  Partner and the
Partnership as follows:
 
       (1) Subscriber has received a copy of the Prospectus, which includes  the
           Limited Partnership Agreement.
 
       (2) Subscriber  is of legal age to  execute this Agreement and is legally
           competent to do so.
 
       (3) Subscriber has either: (a) net  worth of at least $75,000  (exclusive
           of  home, furnishings, and automobiles); or (b) net worth of at least
    $30,000 (exclusive of home, furnishings,  and automobiles) and annual  gross
    income  of at least  $30,000. However, if  Subscriber is a  resident and/ or
    subject to regulation by  one of the states  which imposes more  restrictive
    suitability  requirements than the  foregoing, or requires  a higher minimum
    investment,  as  set  forth  below  under  the  caption  "State  Suitability
    Requirements"  (or in the special Supplement to the Prospectus for residents
    of the state  in which  Subscriber resides), Subscriber's  net worth  and/or
    income  and investment satisfies  the requirements of  such state. (If Units
    are being purchased by  spouses as joint owners,  their joint net worth  and
    annual   income  may  be  used   to  satisfy  applicable  state  suitability
    requirements.) Subscriber  agrees to  provide any  additional  documentation
    requested  by  the General  Partner, as  may be  required by  the securities
    administrators of  certain  states  to confirm  that  Subscriber  meets  the
    applicable   minimum  financial  suitability  standards  to  invest  in  the
    Partnership.
 
       (4) The address set forth on the Signature Page is Subscriber's true  and
           correct residence and Subscriber has no present intention of becoming
    a  resident  of any  other state  or  country. All  the information  that is
    provided on the Signature Page regarding Subscriber is correct and  complete
    as  of the  date of  this Agreement,  and, if  there should  be any material
    change in  such information  prior to  Subscriber's admission  as a  Limited
    Partner,  Subscriber  will  immediately furnish  such  revised  or corrected
    information to the General Partner.
 
       (5) If  Subscriber  is  an  employee   benefit  plan,  to  the  best   of
           Subscriber's knowledge, neither the General Partner, DWR, the Trading
    Advisors,  nor any of their respective affiliates either: (a) has investment
    discretion with respect to the  investment of Subscriber's plan assets;  (b)
    has authority or responsibility to or regularly gives investment advice with
    respect  to  such plan  assets for  a fee  and pursuant  to an  agreement or
    understanding that such advice will serve as a primary basis for  investment
    decisions  with respect  to such  plan assets and  that such  advice will be
    based on the particular investment needs of the plan; or (c) is an  employer
    maintaining  or contributing to such plan. For purposes hereof, an "employee
    benefit plan" shall include plans  and accounts of various types  (including
    their  related trusts) which provide for the accumulation of a portion of an
    individual's earnings or  compensation as well  as investment income  earned
    thereon  free  from  federal  income  tax  until  such  time  as  funds  are
    distributed  from   the   plan,   and  include   corporate   "pension"   and
    profit-sharing plans, "simplified employee pension plans," "Keogh" plans for
    self-employed individuals, and IRAs.
 
       (6) Unless  (7) or (8) below  is applicable, Subscriber's subscription is
           made with Subscriber's funds for Subscriber's own account and not  as
    trustee, custodian, or nominee for another.
 
       (7) The  subscription,  if  made as  custodian  for  a minor,  is  a gift
           Subscriber has made to such minor  and is not made with such  minor's
    funds  or, if  not a gift,  the representations  as to net  worth and annual
    income set forth herein apply only to such minor.
 
                                      B-4
<PAGE>
       (8) If Subscriber is subscribing as a trustee or custodian of an employee
           benefit plan or of an IRA at the direction of the beneficiary of  the
    plan  or  IRA,  the  representations  set  forth  above  apply  only  to the
    beneficiary of such plan or IRA.
 
       (9) If Subscriber is subscribing in a representative capacity, Subscriber
           has full power and authority to purchase the Units and enter into and
    be bound by this Agreement on behalf  of the entity for which Subscriber  is
    purchasing  the Units, and such entity has  full right and power to purchase
    such Units  and enter  into and  be bound  by this  Agreement and  become  a
    Limited Partner pursuant to the Limited Partnership Agreement.
 
ADDITIONAL REPRESENTATION AND WARRANTY FOR EXCHANGE SUBSCRIBERS ONLY:
 
       (10)Subscriber  is the true, lawful, and beneficial owner of the units of
           limited partnership interest  (or fractions thereof)  to be  redeemed
    pursuant  to  this  Agreement,  with full  power  and  authority  to request
    redemption and  a  subsequent  purchase  of  Units.  The  units  of  limited
    partnership  interest (or  fraction thereof) which  are the  subject of this
    redemption request are not subject to any pledge or otherwise encumbered  in
    any fashion.
 
    By  making the representations  and warranties set  forth above, Subscribers
should be aware that they  have not waived any rights  of action which they  may
have  under  applicable  federal or  state  securities laws.  Federal  and state
securities laws provide that any such waiver would be unenforceable. Subscribers
should be  aware, however,  that the  representations and  warranties set  forth
above  may be asserted in  the defense of the  Partnership, the General Partner,
the Trading  Advisors, DWR,  or others  in any  subsequent litigation  or  other
proceeding.

SIGNIFICANT DISCLOSURES
- --------------------------------------------------------------------------------
 
    Subscriber should read the Prospectus in its entirety before completing this
Agreement  and  subscribing  for  Units,  and  should  carefully  consider   the
information contained therein as well as the following information (which is set
forth in detail in the Prospectus) concerning an investment in the Partnership:
 
       (1) The  General Partner and  DWR, the commodity  broker, are each wholly
           owned subsidiaries of Dean Witter,  Discover & Co., and conflicts  of
    interest  therefore  exist. The  principal business  address of  the General
    Partner is Two World Trade Center, 62nd Floor, New York, New York 10048.
 
       (2) DWR will  receive  substantial commodity  brokerage  commissions  and
           certain  transaction fees  and costs  from the  Partnership, and will
    also realize the  benefits of  excess interest earned  on the  Partnership's
    funds  and compensating balance benefits  from deposits of the Partnership's
    funds, subject to  certain limitations,  as described in  the Prospectus.  A
    Limited  Partner will consent  to the execution and  delivery by the General
    Partner on behalf of the Partnership of the Customer Agreement with DWR, and
    to the payment to DWR of such commissions, fees, costs, and benefits.
 
       (3) The performance information in the Prospectus should be read only  in
           conjunction  with the textual description and notes thereto, and such
    data should  not be  interpreted  to mean  that  the Partnership  will  have
    similar  results or will  realize any profits  whatsoever. A Limited Partner
    will be  deemed to  have consented  to  the execution  and delivery  by  the
    General  Partner on behalf  of the Partnership  of the Management Agreements
    with each Trading Advisor  (as described in the  Prospectus), and with  such
    other trading advisors as the General Partner may retain from time to time.
 
       (4) Units  cannot be transferred  or assigned except as  set forth in the
           Limited Partnership Agreement. Units may be redeemed at the option of
    a Limited Partner as of, but not  before, the sixth month end following  the
    closing  at which such  person first becomes  a Limited Partner. Thereafter,
    Units may  be redeemed  as  of the  end of  any  month. However,  any  Units
    redeemed  at the end of the sixth or at  or prior to the end of the twelfth,
    eighteenth or twenty-fourth month following the closing at which such  Units
    are  issued will  be assessed  a redemption  charge equal  to 3%,  2% or 1%,
    respectively, of  the  Net  Asset Value  of  a  Unit on  the  date  of  such
    redemption.  The foregoing charges will be paid to DWR. A limited partner in
    any of the other commodity pools for which the General Partner serves as the
    general partner and commodity pool operator who redeemed all or a portion of
    his interest in  one of  such other partnerships  on or  after December  31,
    1995,  and purchases Units  will not be subject  to the foregoing redemption
    charges or restrictions under the circumstances described below. The  number
    of  Units (determined on a per closing  basis), expressed as a percentage of
    Units purchased, which are not subject to a redemption charge is  determined
    by  dividing (a)  the dollar amount  received upon redeeming  an interest in
    such other  partnership  and  used  to  purchase  Units  by  (b)  the  total
    investment  in the Partnership. Redemptions of Units will be deemed to be in
    the order in which they are  purchased (assuming purchases at more than  one
    closing),  with Units not subject to a  redemption charge being deemed to be
    the first Units purchased at a closing. Subscribers who purchase $500,000 or
    more of Units will not be subject to the redemption charges described above.
    Units may  only be  redeemed upon  5 business  days' written  notice to  the
    General  Partner prior to the effective date  of a redemption, which will be
    the last day of a calendar month.
 
       (5) All subscriptions  are  subject to  acceptance  or rejection  by  the
           General  Partner  in  whole  or  in  part  for  any  reason  and  are
    irrevocable  by  Subscribers,  subject  to  the  limited  revocation   right
    described on page 3 of this Agreement.

Partner of the Partnership. Subscriber hereby agrees to
 
                                      B-7

ITEM 17.  UNDERTAKINGS.
 
    The undersigned Registrant hereby undertakes:
 
    (1)To file, during any  period in which  offers or sales  are being made,  a
       post-effective  amendment to this Registration  Statement: (a) to include
any prospectus required by Section 10(a)(3)  of the Securities Act of 1933;  (b)
to  reflect in the  Prospectus any facts  or events arising  after the effective
date of the Registration Statement (or the most recent post-effective  amendment
thereof) which, individually or in the aggregate, represent a fundamental change
in  the information set forth in the  Registration Statement; and (c) to include
any material information with respect to the plan of distribution not previously
disclosed  in  the  Registration  Statement  or  any  material  change  to  such
information in the Registration Statement.
 
    (2)That,  for the purpose of determining  any liability under the Securities
       Act of 1933, each such post-effective  amendment shall be deemed to be  a
new  registration statement relating to the  securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial  bona
fide offering thereof.
 
    (3)That all post-effective amendments will comply with the applicable forms,
       rules and regulations of the Securities and Exchange Commission in effect
at the time such post-effective amendments are filed.
 
    (4)To remove from registration by means of a post-effective amendment any of
       the securities being registered which remain unsold at the termination of
the offering.
 
    (5)Insofar  as indemnification for liabilities  arising under the Securities
       Act of  1933 may  be permitted  to directors,  officers, and  controlling
persons  of the Registrant  pursuant to the  foregoing provisions, or otherwise,
the Registrant  has been  advised that  in  the opinion  of the  Securities  and
Exchange  Commission such indemnification is  against public policy as expressed
in the Act  and is,  therefore, unenforceable.  In the  event that  a claim  for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant of expenses incurred or paid  by a director, officer, or  controlling
person  of the  Registrant in  the successful  defense of  any action,  suit, or
proceeding) is  asserted by  such director,  officer, or  controlling person  in
connection  with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to  a  court  of  appropriate  jurisdiction  the  question  whether  such
