                       S&P MANAGED FUTURES INDEX FUND, LP

SUMMARY

THE FUND AND THE GENERAL PARTNER

     S&P Managed Futures Index Fund, LP is a futures investment fund designed to
seek returns that substantially track the Standard & Poor's Managed Futures
Index(TM), referred to as the Index, before expenses of the Fund.

     RefcoFund Holdings, LLC serves as the Fund's general partner. The Fund is a
Delaware limited partnership formed on May 13, 2003. The Fund's main office is
located at the office of the general partner - 550 W. Jackson, Suite 1300,
Chicago, Illinois 60661 (telephone: (312) 788-2000).

     The general partner has been registered with the Commodity Futures Trading
Commission as a commodity pool operator since October 14, 1981 and as a
commodity trading advisor since September 21, 1993 and is a member of the NFA.
As of May 31, 2003, the general partner was managing approximately $63 million
in client assets.

     If the Fund is successful, it can provide valuable diversification to
traditional portfolios of stocks and bonds, as the Fund's performance should be
generally unrelated to the general stock and bond markets.

THE INDEX

     Standard & Poor's has long been recognized worldwide as a global provider
of equity indices. In October 2002, Standard & Poor's launched the Standard &
Poor's(R) Hedge Fund Index. In January 2003, Standard & Poor's launched the
Index, which is an expansion of the managed futures subset of the Standard &
Poor's Hedge Fund Index. The Index is designed to offer an investable benchmark
that is representative of the managed futures segment of hedge fund investing.
The Index focuses on the systematic, trend-following trading methodologies that
constitute the significant majority of managed futures investment strategies.
Constituents of the Index are programs that use managed futures strategies.

     The general partner will pursue the Fund's investment objective by
allocating substantially all of the Fund's assets to SPhinX(TM) Managed Futures
Fund SPC, referred to as the Index SPC, a Cayman Islands special purpose
company. The Index SPC allocates its assets to portfolio managers that generally
employ a broad range of systematic trading strategies in the futures markets.
Other markets, such as the interbank foreign exchange market, may be used as
well.

     The Index SPC is designed to track the Index, and thus provide its
investors with exposure to a broad cross section of systematic managed futures
strategies through a single investment. As a limited partner you will have
access to a variety of managed futures strategies that ordinarily would not be
available without high minimum investment requirements. The Fund

                                        1
<Page>

provides you with access to professionally selected managers who are considered
to be representative of systematic managed futures strategies.

     The portfolio managers that are included in the Index are selected by
Standard & Poor's Index Committee based on, among other things, an analysis of:

     -    the portfolio manager's trading strategy;

     -    risk/return characteristics;

     -    volatility levels;

     -    performance during various time periods and market cycles; and

     -    the structure of the portfolio manager's portfolio and the types of
instruments held.

     Standard & Poor's is responsible for calculating the Index and publishes
Index values on the Standard & Poor's website: www.standardandpoors.com. The
Index is rebalanced annually or as otherwise required by Standard & Poor's.
Addition or deletion of Index constituents is at the sole discretion of Standard
& Poor's Index Committee.

USE OF PROCEEDS

     The Fund expects that the proceeds from the sale of Units, net of the
Fund's initial and ongoing organizational and offering costs as well as amounts
the Fund retains to cover ongoing operating expenses, will be invested in the
Index SPC as soon as practicable after the receipt of such proceeds by the Fund.

THE OFFERING

     Units in the Fund are being offered for an initial offering period
beginning on the date of this prospectus and ending 60 calendar days later. The
general partner may end the initial offering period earlier or extend it for an
additional 60 days. During the initial offering period, you may buy Units for
$1,000 each. All subscriptions received during the initial offering period will
be held in an interest bearing escrow account with Fifth Third Bank. If the Fund
begins trading at the end of the initial offering period, interest earned on
subscriptions will be treated as interest earned by the Fund. If 30,000 Units
are not sold during the initial offering period, or, if for any other reason the
Fund does not begin trading at the end of the initial offering period, the
offering of Units will terminate and your subscription will be returned to you
with interest within 5 business days.

     Once the Fund has begun trading, you may buy Units at the net asset value
per Unit as of the first business day of each calendar month in which they are
offered. Interest earned on subscriptions submitted prior to the first business
day of the calendar month will be treated as interest earned by the Fund. The
net asset value per Unit is determined by dividing the Fund's net assets (its
assets minus its liabilities) by the number of Units outstanding on the date the
calculation is being performed.

                                        2
<Page>

     The minimum investment is $10,000, although the minimum initial investment
for an individual retirement account is $3,000. Existing investors subscribing
for additional Units may do so in $2,500 minimums. Units will be sold in
fractions calculated to three decimal places.

     To subscribe, you must complete and sign the Subscription Agreement and
Power of Attorney Signature Page that accompanies this prospectus and deliver it
to your selling agent. You must submit these documents at least five business
days (and cleared funds to purchase the Units at least three business days)
before the first business day of the calendar month in which the subscription is
to be effective.

IS THE FUND A SUITABLE INVESTMENT FOR YOU?

     You should consider investing in the Fund if you are interested in its
potential to produce returns that are generally unrelated to those of stocks and
bonds and you are prepared to risk the loss of all or a significant portion of
your investment.

     The Fund is a diversification opportunity for an investment portfolio, not
a complete investment program.

     You should consider an investment in the Fund to be a three to five year
commitment.

     To invest, you must, at a minimum, have either (1) a net worth of at least
$150,000, exclusive of home, furnishings and automobiles, or (2) a net worth,
similarly calculated, of at least $45,000 and an annual gross income of at least
$45,000. A number of states in which the Units are offered impose higher
suitability standards. These standards are regulatory minimums only, and just
because you meet the standard does not necessarily mean the Units are a suitable
investment for you.

     You should not invest more than 10% of your net worth (exclusive of home,
furnishings and automobiles) in the Fund.

     You should read this prospectus carefully and discuss with your selling
agent any questions you have about the Fund before making an investment.

MAJOR RISKS OF THE FUND

- -    The Fund is speculative. You may lose all or substantially all of your
investment in the Fund.

- -    The Fund is newly formed and has no performance history. The Index SPC has
a very limited actual performance history. The past performance of the Index SPC
is not necessarily indicative of future results.

- -    The Fund is subject to substantial charges. You will sustain losses if the
Fund is unable to generate sufficient trading profits to offset its fees and
expenses.

- -    The Units are not a liquid investment. No secondary market exists for the
Units. You may redeem the Units only as of the last business day of each month.
A redemption fee applies

                                        3
<Page>

if you redeem Units within 12 months of their original purchase. There are
substantial restrictions on the ability of the Fund to make withdrawals from the
Index SPC that further reduces the liquidity of the Fund.

- -    Although the Fund seeks to track the performance of the Index, certain
factors, including expenses, will cause a deviation between Fund's performance
and the Index's performance.

- -    The Fund is subject to various conflicts of interests as further described
herein, including those related to the following: (1) the general partner, the
selling agent and the clearing broker for the Index SPC are affiliated; and (2)
your selling agent will receive upfront and ongoing compensation in connection
with your investment in the Fund.

- -    The market prices of commodity interest contracts fluctuate rapidly. In
addition, commodity interest contracts are typically traded on margin. This
means that a small amount of capital can be used to invest in contracts of much
greater total value. The resulting leverage magnifies the impact of both profit
and loss.

     See pages 7 through 14 for a complete description of the risks of an
investment in the Fund.

REDEMPTIONS

     You may redeem your Units as of the last business day of any calendar
month. You must submit your written redemption request at least 10 business
days' prior to the redemption date. A redemption fee of 3% of net asset value
per Unit applies if you redeem Units within 12 months of their original
purchase. After the 12th month following purchase of a Unit, no redemption fees
apply. There are substantial restrictions on the ability of the Fund to make
withdrawals from the Index SPC that further reduces the liquidity of the Fund.

BREAKEVEN TABLE

     The "Breakeven Table" below indicates the approximate percentage and dollar
returns required for the redemption value of an initial $10,000 investment in
the Units to equal the amount originally invested 12 months after issuance. The
"Breakeven Table," as presented, is an approximation only.

NOTES TO "BREAKEVEN TABLE"

(1)  The foregoing break-even analysis assumes that the Units have a constant
month-end net asset value. Calculations are based on $10,000 as the net asset
value per Unit. See "Charges" at page 31 of this prospectus for an explanation
of the expenses included in the "Breakeven Table."

(2)  The Fund will pay the general partner a monthly management fee of 3.75% per
annum. From this amount the general partner will pay the organizational and
initial offering expenses of the Fund. In addition, beginning in the 13th month
following the purchase of any Units, the general partner will pay to the selling
agents of the Units a monthly trailing commission equal to 0.1875% of the Fund's
month-end net assets (a 2.25% annual rate) per Unit multiplied by the number of
Units placed by the selling agent for providing additional services in
connection with the Units.

(3)  The Fund will pay the general partner a monthly administrative fee of 0.25%
per annum.

(4)  Ordinary expenses are paid as incurred. For this "Breakeven Table" such
amounts have been estimated. These expenses include the legal, audit and other
routine expenses of the Fund.

(5)  The Fund will pay its ongoing offering expenses. These expenses are not
expected in the aggregate to exceed 0.25% per annum of the month-end net asset
value of the Fund.

                                        5
<Page>

(6)  The general partner will pay the selling agents an upfront selling
commission of 3% of the subscribed amount. The general partner will be
reimbursed monthly by the Fund at a rate of 0.75% per annum, provided, however,
that the Fund will cease to reimburse the general partner with respect to any
upfront selling commission when the general partner has received the amount
originally paid by the general partner, plus interest.

(7)  A redemption fee of 3% of net asset value per Unit, payable to the General
Partner, applies if you redeem Units within 12 months of their original
purchase.

     The Fund will also be required to pay its pro rata portion of the expenses
of the Index SPC. These expenses include (1) management fees and incentive fees,
if any, paid to the portfolio managers; (2) fees paid to the Index SPC's
administrator to administer the Index SPC; (3) brokerage commissions and other
transaction-related expenses of the Index SPC; and (4) accounting, audit and
legal expenses, custodial fees and any extraordinary expenses of the Index SPC.
Because these expenses are costs of the Index, and as such are reflected in the
performance of the Index SPC, they are not included in the break-even estimate
set forth above.

FEDERAL INCOME TAX ASPECTS

     The Fund will be treated as a partnership for federal income tax purposes.
You will be taxed each year on the Fund's income whether or not you redeem any
of your Units or receive distributions from the Fund. The general partner does
not intend to make any distributions. Accordingly, unless you redeem Units, you
will not have a source of income from the Fund to pay your taxes.

     40% of any trading profits on U.S. exchange-traded contracts are taxed as
short-term capital gains at ordinary income rates, while 60% of any trading
profits are taxed as long-term capital gains at a 15% maximum rate for
individuals for sales and exchanges occurring after May 5, 2003 and prior to
January 1, 2009 (and 20% for sales or exchanges occurring thereafter). The
Fund's trading gains from other contracts will be primarily short-term capital
gains. This tax treatment applies regardless of how long a limited partner holds
Units. Interest income is taxed at ordinary income rates.

     Losses on the Units may be deducted against capital gains. However, capital
losses in excess of capital gains may only be deducted against ordinary income
to the extent of $3,000 per year. Consequently, you could pay tax on the Fund's
interest income even though you have lost money on your Units.

THE FUTURES AND FORWARD MARKETS; SPOT AND SWAP CONTRACTS

     Futures contracts are generally traded on exchanges and call for the future
delivery of various commodities or cash settlement of certain financial
instruments.

     Forward currency contracts are traded off-exchange through banks or
dealers.

     Futures and forward trading is a "zero-sum" risk transfer economic
activity. For every gain realized by a futures and forward trader, there is an
equal and offsetting loss suffered by another.

                                        6
<Page>

     Spot contracts are cash market transactions in which the buyer and seller
agree to the immediate purchase and sale of a specific commodity, usually with a
short settlement period. Swap contracts generally involve an exchange of a
stream of payments between contracting parties. Neither spot nor swap contracts
are exchange-traded.

THE RISKS YOU FACE

SET FORTH BELOW ARE THE PRINCIPAL RISKS ASSOCIATED WITH AN INVESTMENT IN THE
FUND. YOU SHOULD CONSIDER THESE RISKS WHEN MAKING YOUR INVESTMENT DECISION. YOU
SHOULD NOT INVEST IN UNITS UNLESS YOU CAN AFFORD TO LOSE ALL OF YOUR INVESTMENT.

YOU COULD LOSE YOUR ENTIRE INVESTMENT IN THE FUND

     The Fund will pursue its investment objective by investing in the Index
SPC, which allocates its assets among the portfolios managers. The Index SPC
will be subject to all of the risks associated with the investment and trading
by the portfolio managers. There are some general market conditions in which any
given investment strategy is unlikely to be profitable. Neither the Fund, the
Index SPC nor the portfolio managers will have any ability to control or predict
these market conditions. The investment approach utilized on behalf of the Fund
and the Index SPC may not be successful. You could lose all or substantially all
of your investment in the Fund.

THE FUND HAS NO OPERATING HISTORY; PAST PERFORMANCE IS NOT INDICATIVE OF FUTURE
PERFORMANCE

     The Fund is newly formed and has no performance history. The Index SPC has
a very limited operating history. The past performance of the Index SPC is not
necessarily indicative of future results. The portfolio managers will be
selected based in part on their performance history and implementation of a
strategy deemed by Standard & Poor's to be representative of managed futures
programs in general. The experience of some portfolio managers may be limited.
Furthermore, each portfolio manager is free to alter its managed futures
strategy implementation as it deems appropriate from time to time. Significant
changes in strategy would require a review by Standard & Poor's. Market
conditions and trading approaches are continually changing, and a portfolio
manager's past successful performance may be largely irrelevant to its prospects
for future profitability.

THE FUND IS SUBJECT TO SUBSTANTIAL FEES AND EXPENSES

     The Fund is subject to significant fees and expenses. In order for the Fund
to be profitable and for the investors to realize any profits the investment
profits realized by the Fund must exceed these fees and expenses. The Fund will
pay management and administrative fees to the general partner, will reimburse
the general partner for selling commissions and will pay its pro rata share of
the fees and expenses of the Index SPC. Some of the strategies and techniques
employed by the portfolio managers may require frequent trades to take place
and, as a consequence, portfolio turnover and brokerage commissions may be
greater than for other investment entities of similar size. In addition, the
Fund will pay its operating expenses

                                        7
<Page>

regardless of the profitability of the Fund. You will sustain losses if the Fund
is unable to generate sufficient trading profits and interest income to offset
its fees and expenses.

AN INVESTMENT IN THE FUND IS NOT LIQUID

     The Units are not a liquid investment. There is no secondary market for the
Units. You may redeem your Units only as of the first business day of a calendar
month, and you must give the Fund at least 10 business days' prior written
notice of your intent to redeem. A redemption fee will apply if you redeem your
Units within 12 months after their original purchase. There are also substantial
restrictions on the ability of the Fund to make withdrawals from the Index SPC
that further reduces the liquidity of the Fund.

THE FUND WILL NOT PRECISELY TRACK THE INDEX

     Although the Fund seeks to track the performance of the Index, various
factors can cause a deviation between the performance of the Fund and the
performance of the Index. These factors include (1) the expenses of the Fund and
the Index SPC, (2) limitations on the Fund's investments resulting from the need
to comply with the Fund's investment restrictions or with regulatory or tax law
requirements, and (3) the need to maintain a portion of the Fund's assets in
cash or short-term investments to maintain liquidity to effect redemptions and
to pay expenses. The performance of the Fund will not correspond precisely to
the performance of the Index.

RISKS RELATED TO MANAGED FUTURES TRADING

     THE INDEX SPC WILL BE SUBJECT TO MARKET FLUCTUATIONS. Managed futures
trading involves trading in various commodity interests and financial
instruments. The market prices of futures contracts fluctuate rapidly. Prices of
futures contracts traded by the portfolio managers are affected generally, among
other things, by (1) changing supply and demand relationships, (2) agricultural,
trade, fiscal, monetary and exchange control programs and (3) policies of
governments, and national and international political and economic events. The
profitability of the Index SPC depends entirely on capitalizing on fluctuations
in market prices.

     AS A RESULT OF LEVERAGE, SMALL CHANGES IN THE PRICE OF THE PORTFOLIO
MANAGERS' POSITIONS MAY RESULT IN SUBSTANTIAL LOSSES. Commodity interest
contracts are typically traded on margin. This means that a small amount of
capital can be used to invest in contracts of much greater total value. The
resulting leverage means that a relatively small change in the market price of a
contract can produce a substantial loss. Like other leveraged investments, any
purchase or sale of a contract may result in losses in excess of the amount
invested in that contract. The portfolio managers may lose more than their
initial margin deposits on a trade.

     THE PORTFOLIO MANAGERS' TRADING WILL BE SUBJECT TO EXECUTION RISKS. Market
conditions may make it impossible for the portfolio managers to execute a buy or
sell order at the desired price, or to close out an open position. Daily price
fluctuation limits are established by the exchanges and approved by the CFTC.
When the market price of a contract reaches its daily price fluctuation limit,
no trades can be executed at prices outside the limit. The holder of a contract
may therefore be locked into an adverse price movement for several days or more
and lose considerably more than the initial margin put up to establish the
position. Thinly traded or illiquid markets also can make it difficult or
impossible to execute trades.

                                        8
<Page>

     THE INDEX SPC WILL BE SUBJECT TO COUNTERPARTY RISKS. If the Index SPC's
clearing brokers become bankrupt or insolvent, or otherwise default on their
obligations to the Index SPC, the Index SPC may not receive all amounts owed to
it in respect to its trading, despite the clearinghouse fully discharging all of
its obligations. Furthermore, in the event of the bankruptcy of one of the
clearing brokers, the Index SPC could be limited to recovering only a pro rata
share of all available funds segregated on behalf of the clearing broker's
combined customer accounts, even though property specifically traceable to the
Index SPC (for example, Treasury bills deposited by the Index SPC with the
clearing broker as margin) was held by the clearing broker. In addition, some of
the instruments which the Index SPC may trade are traded in markets in which
performance is the responsibility only of the individual counterparty with whom
the trader has entered into a contract and not of an exchange or clearing
corporation. The Index SPC will be subject to the risk of the inability or
refusal to perform on the part of the counterparties with whom those types of
contracts are traded.

     THE INDEX SPC'S POSITIONS WILL BE SUBJECT TO SPECULATIVE LIMITS. The CFTC
and domestic exchanges have established speculative position limits on the
maximum futures position which any person, or group of persons acting in
concert, may hold or control in particular futures contracts or options on
futures contracts traded on U.S. commodity exchanges. Under current regulations,
other accounts of the portfolio managers are combined with the positions held by
the Index SPC for position limit purposes. This trading could preclude
additional trading in these commodities by the portfolio manager for the account
of the Index SPC.

     TRADING ON FOREIGN EXCHANGES PRESENTS GREATER RISK THAN TRADING ON U.S.
EXCHANGES. The portfolio managers may trade contracts on non-U.S. exchanges.
Non-U.S. trading involves risks -- including exchange-rate exposure, excessive
taxation, possible governmental regulation and lack of regulation -- which U.S.
trading does not. Some non-U.S. markets, in contrast to U.S. exchanges, are
"principals' markets" where performance is the responsibility only of the
individual member with whom the trader has entered into a contract and not of
any exchange or clearing corporation. In addition, the Index SPC's rights and
responsibilities if a non-U.S. exchange or clearinghouse defaults or declares
bankruptcy are likely to be more limited than if a U.S. exchange does the same.

     THE PORTFOLIO MANAGERS MAY TRADE FORWARD CONTRACTS. Forward contracts are
not traded on exchanges and the Index SPC will not receive the regulatory
protections of the exchanges or the CFTC in connection with such trading. As a
result, the Index SPC may incur substantial losses if the banks and dealers
acting as principals on forward contracts are unable to perform. In addition,
there are no limitations on daily price moves in forward contracts, and
speculative position limits do not apply to forward contract trading. Further,
there have been periods when 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 will buy and that at which they will
sell.

     THE PORTFOLIO MANAGERS MAY ENTER INTO SWAP AND SIMILAR TRANSACTIONS. Swap
contracts are not traded on exchanges and are not subject to the same type of
government regulation as exchange markets. As a result, many of the protections
afforded to participants on organized exchanges and in a regulated environment
are not available in connection with these transactions.

                                        9
<Page>

The swap markets are "principals' markets," in which performance with respect to
a swap contract is the responsibility only of the counterparty to the contract,
and not of any exchange or clearinghouse. As a result, the Index SPC is subject
to the risk of the inability or refusal to perform with respect to swap
contracts on the part of the counterparties with which the portfolio managers
trade. There are no limitations on daily price movements in swap transactions.
Speculative position limits are not applicable to swap transactions, although
the counterparties with which the portfolio managers trade may limit the size or
duration of positions available to the portfolios managers as a consequence of
credit considerations. Participants in the swap markets are not required to make
continuous markets in the swap contracts they trade. Participants could refuse
to quote prices for swap contracts or quote prices with an unusually wide spread
between the price at which they are prepared to buy and the price at which they
are prepared to sell.

     THE PORTFOLIO MANAGERS MAY ENGAGE IN EXCHANGES OF FUTURES FOR PHYSICALS. An
exchange of futures for physicals 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 these transactions are executed are negotiated between the
parties. Regulatory changes may in the future prevent the portfolio managers
from exchanging futures for physicals, which could adversely affect performance
of the Index SPC.

     THE INDEX SPC MAY TRADE SECURITY FUTURES PRODUCTS. The portfolio managers
may purchase and sell single stock futures contracts and other security futures
products. A single stock future obligates the seller to deliver (and the
purchaser to take delivery of) a specified equity security to settle the futures
transaction. Other security futures products include "narrow-based" stock index
futures contracts (in general, contracts based on the value of nine or fewer
securities in a specific market or industry sector, such as energy, health care
or banking) and futures contracts based on exchange-traded funds, or ETFs, that
are designed to track the value of broader stock market indices (such as the Dow
Jones Industrial Average or the NASDAQ 100 Index). Single stock futures and
other security futures products are relatively illiquid and trade on a limited
number of exchanges. The margin required with respect to single stock futures
(usually at least 20% of the face value of the contract) generally is higher
than the margin required with respect to other types of futures contracts (in
some cases as low as 2% of the face value of the contract). The resulting lower
level of leverage available to the portfolio managers with respect to security
futures products may adversely affect the Index SPC's performance. Security
futures products are typically traded on electronic trading platforms and are
subject to risks related to system access, varying response time, security and
system or component failure. In addition, although the Index SPC's broker will
be required to segregate the Index SPC's trades, positions and funds from those
of the broker itself as required by CFTC regulations, the insurance provided to
securities customers by the Securities Investor Protection Corporation, or SIPC,
will not be applicable to the Index SPC's security futures positions because
SIPC protection does not apply to futures accounts.

     SYSTEMATIC STRATEGIES DO NOT CONSIDER FUNDAMENTAL TYPES OF DATA. Most of
the Index SPC's assets will be allocated to portfolio managers that rely on
technical, systematic strategies that do not take into account factors external
to the market itself. The widespread use of

                                       10
<Page>

technical trading systems frequently results in numerous managers attempting to
execute similar trades at or about the same time, altering trading patterns and
affecting market liquidity. Furthermore, the profit potential of trend-following
systems may be diminished by the changing character of the markets, which may
make historical price data (on which technical programs are based) only
marginally relevant to future market patterns.

     INCREASED COMPETITION AMONG TREND-FOLLOWING TRADERS COULD REDUCE THE INDEX
SPC'S PROFITABILITY. A substantial number of commodity trading advisors use
technical trading systems, particularly trend-following systems, like some of
the portfolio managers' systems. As the amount of money under the management of
such systems increases, competition for the same positions increases, making the
positions more costly and more difficult to acquire.

THE FUND IS DEPENDENT UPON THIRD PARTIES

     The Fund does not control the Index SPC, PlusFunds, or any portfolio
manager, and has no role in the choice of portfolio managers, any portfolio
manager's choice of investments or any other investment decisions of the Index
SPC. The Fund will be dependent upon the expertise and abilities of the
portfolio managers who will have investment discretion over assets allocated to
them. There can be no assurance that the services of PlusFunds or of a portfolio
manager will be available for any length of time, or that the Index SPC will
remain available for investment by the Fund.

THE FUND WILL HAVE LIMITED ACCESS TO INFORMATION REGARDING THE INDEX SPC AND THE
PORTFOLIO MANAGERS

     The Fund will be dependent on PlusFunds and the Index SPC's independent
administrator to provide it with periodic reports and other information. The
Fund may not be provided with detailed information regarding the precise
investments made by a portfolio manager because some of this information may be
considered proprietary or otherwise confidential. This lack of access to
information may make it more difficult for the Fund to evaluate the Index SPC
and the portfolio managers and to value the assets of the Fund.

THE FUND MUST RELY ON THE INDEX SPC WHEN CALCULATING NET ASSET VALUE

     The net asset values received by the Fund from the Index SPC may be subject
to revision through annual audit of the Index SPC. As a result, revisions to the
Fund's gain and loss calculations may occur. Any revisions not deemed material
in the sole discretion of the general partner will not result in an adjustment
to prior subscription or redemption prices for the Fund. Moreover, in some
cases, the Fund will have little ability to assess the accuracy of the
valuations of its investment in the Index SPC that are received from PlusFunds
or from the Index SPC or its administrator. There are no market quotations
available to use in valuing the Fund's investments in the Index SPC. As a
result, these investments will be valued at their fair values as determined in
accordance with procedures adopted in good faith by the general partner. These
valuations may not in all cases accurately reflect the values of the Fund's
investments in the Index SPC. These inaccuracies may adversely affect the Fund
or investors who purchase or redeem Units.

                                       11
<Page>

THE FUND MAY LOSE THE STANDARD & POOR'S LICENSE

     Standard & Poor's has granted a license to PlusFunds to use various
trademarks as well as the right to utilize the Index in connection with the
operation of various investment products. PlusFunds has sublicensed some of
these rights to Refco Group Ltd., LLC and its affiliates, referred to as the
Refco Group. Under various circumstances, the license agreement between
PlusFunds and Standard & Poor's or the sublicense agreement between PlusFunds
and the Refco Group may be terminated. In the event of a termination, the Fund
may be unable to continue to utilize the trademarks and continued operation of
the Fund may become impractical or impossible.

INCENTIVE-BASED COMPENSATION MAY AFFECT PORTFOLIO MANAGERS' TRADING

     The portfolio managers will be entitled to compensation based upon net
trading gain in the value of the assets they manage. Incentive-based
arrangements may give them incentives to engage in transactions that are more
risky or speculative than they might otherwise make because speculative
investments might result in higher profits in which the portfolio manager would
participate, resulting in higher incentive fees to them. On the other hand,
those investments might result in larger losses to the Index SPC. The portfolio
managers will not return an incentive fee for a period in which there is net
trading gain if, in a subsequent period, the investments under their management
suffer a net trading loss. In addition, because the incentive fee for each
portfolio manager is based solely on its performance, and not the overall
performance of the Index SPC, the Fund may indirectly pay an incentive fee to
one or more portfolio managers during periods when the Index SPC, and thus the
Fund, are not profitable on an overall basis.

THE FUND DOES NOT ANTICIPATE MAKING DISTRIBUTIONS

     The general partner does not intend to make distributions to the limited
partners but intends to re-invest substantially all of the Fund's income and
gains for the foreseeable future. You will be liable to pay taxes on your
allocable share of Fund taxable income. Therefore, you may need to pay tax
liabilities out of separate funds or redemptions from the Fund.

POSSIBLE EFFECT OF REDEMPTIONS ON THE VALUE OF THE UNITS

     Substantial redemptions of Units could require the Fund and the Index SPC
to liquidate investments more rapidly than otherwise desirable in order to raise
the necessary cash to fund the redemptions and, at the same time, achieve a
market position appropriately reflecting a smaller equity base. This could make
it more difficult to recover losses or generate profits. Illiquidity in the
markets could make it difficult to liquidate positions on favorable terms, and
may result in losses.

THE GENERAL PARTNER HAS THE ABILITY TO SUSPEND REDEMPTION RIGHTS

     Under some circumstances, the general partner may suspend your right to
redeem all or some of your Units. This may occur if the general partner
determines that redemptions would impair the ability of the Fund to meet its
objectives or if a market disruption makes it impossible or impracticable to
value the Units or liquidate Fund assets. IF REDEMPTION RIGHTS ARE

                                       12
<Page>

SUSPENDED, THE UNITS SUBJECT TO THE REDEMPTION REQUEST WILL NOT BE REDEEMED AND
WILL CONTINUE TO BE SUBJECT TO MARKET AND OTHER RISKS. The Index SPC may suspend
the Fund's redemption rights for similar reasons with similar consequences.

THE FUND'S STATUS AS A PARTNERSHIP

     The general partner has been advised by its counsel that under current
federal income tax laws and regulations the Fund should be classified as a
partnership and not as an association taxable as a corporation. In addition, the
general partner has been advised by its counsel that under current federal
income tax laws the Fund should not be classified as a so-called publicly traded
partnership. This advice is not binding upon the IRS. If the Fund were taxed as
a corporation for federal income tax purposes, income or loss of the Fund would
not be passed through to the limited partners, and the Fund would be subject to
tax on its income at the rates of tax applicable to corporations without any
deductions for distributions to the Fund. In addition, all or a portion of
distributions made to limited partners could be taxable to the limited partners
as dividends.

YOU WILL BE TAXED EACH YEAR ON YOUR SHARE OF FUND PROFITS

     You will be taxed on your share of Fund income or gain each year, whether
or not you redeem Units or receive distributions from the Fund. Because a
substantial portion of the Index SPC's open positions are "marked-to-market" at
the end of each year, some of your tax liability will be based on unrealized
gains which the Fund may, in fact, never realize. 40% of any trading profits on
U.S. exchange-traded contracts are taxed as short-term capital gains at ordinary
income rates, while 60% of any trading profits are taxed as long-term capital
gains at a 20% maximum rate for individuals. These rates apply regardless of how
long the Index SPC holds a contract, or an investor his or her Units.

     Over time, the compounding effects of the annual taxation of the Fund's
income are material to the economic consequences of investing in the Fund. For
example, a 10% compound annual rate of return over five years would result in an
initial $10,000 investment compounding to $16,105. However, after factoring in a
30% tax rate each year, the result would be $14,025.

YOU WILL BE TAXED ON THE FUND'S INTEREST INCOME EVEN IF THE FUND SUFFERS TRADING
LOSSES

     Losses on the Fund's trading are almost exclusively capital losses.
Non-corporate investors may use net capital losses to offset up to $3,000 of
ordinary income each year. So, for example, if your share of the Fund's trading
(I.E., capital) loss was $3,000 in a given fiscal year and your share of
interest income was $5,000, you would incur a net loss in the net asset value of
your Units equal to $5,000, but would nevertheless recognize taxable income of
$2,000.

LIMITATIONS ON THE DEDUCTIBILITY OF INVESTMENT ADVISORY FEES

     The general partner does not intend to treat the ordinary expenses of the
Fund as "investment advisory fees" for federal income tax purposes. The general
partner believes that this is the position adopted by virtually all United
States futures fund sponsors. However, were the ordinary expenses of the Fund
characterized as investment advisory fees, non-corporate

                                       13
<Page>

taxpayers would be subject to substantial restrictions on the deductibility of
those expenses, would pay increased taxes in respect of an investment in the
Fund and could actually recognize taxable income despite having incurred a
financial loss.

THE IRS COULD AUDIT BOTH THE FUND AND INDIVIDUAL LIMITED PARTNERS

     The IRS could audit the Fund's tax returns and require the Fund to adjust
the returns. If an audit results in an adjustment, you could be audited and
required to pay additional taxes, plus interest and possibly penalties.

THE FUND DOES NOT HAVE SOME STATUTORY REGISTRATIONS

     The Fund has not registered as an investment company or a "mutual fund,"
which would subject the Fund to extensive regulation by the SEC under the
Investment Company Act. Therefore, you do not have the protection provided by
such legislation, which, among other things, (1) requires that an investment
company's board of directors, including a majority of disinterested directors,
approve some of its activities and contractual relationships, and (2) prohibits
an investment company from engaging in some transactions with its affiliates.
Further, to the extent registration under or compliance with these laws is
required, the Fund may incur significant burdens and expenses in connection
therewith. Moreover, the general partner is not registered as an investment
adviser under the Investment Advisers Act of 1940 or any similar state law.
However, the general partner is registered as a commodity pool operator and a
commodity trading advisor and is subject to regulation as such by the CFTC and
the NFA.

INVESTMENT FACTORS

     ALTHOUGH THERE CAN BE NO ASSURANCE THAT THE PORTFOLIO MANAGERS WILL TRADE
SUCCESSFULLY ON BEHALF OF THE INDEX SPC OR THAT THE FUND WILL AVOID SUBSTANTIAL
LOSSES, IF THE FUND IS SUCCESSFUL, AN INVESTMENT IN THE FUND OFFERS INVESTORS
THE FOLLOWING POTENTIAL ADVANTAGES.

THE GENERAL PARTNER

     The general partner's experience and familiarity with the managed futures
industry assist the general partner in its ongoing monitoring of the Index SPC
as well as in the administration of the Fund. The general partner's principals
have over 100 years of combined experience in the investment field. As of May
31, 2003, the general partner had approximately $63 million under management.

THE INDEX

     The Index is designed to offer an investable benchmark that is
representative of the managed futures segment of hedge fund investing. By
investing in the Fund, you will have access to a broad cross section of
systematic managed futures strategies through a single investment.

                                       14
<Page>

INVESTMENT DIVERSIFICATION

     If you are not prepared to spend substantial time trading in the futures
and forward markets, you may nevertheless participate in these markets through
investing in the Fund. An investment in the Fund can provide valuable
diversification to a traditional portfolio of stocks and bonds. The general
partner believes that the profit potential of the Fund does not depend upon
favorable general economic conditions and that the Fund is just as likely to be
profitable or unprofitable during periods of declining stock and bond markets as
at any other time.

     Allocating a small portion of your investment portfolio to a managed
futures investment, such as the Fund, can potentially enhance the performance of
the portfolio. Modern portfolio theory suggests that a diverse portfolio with
positively performing assets that have little or no correlation with each other
should have higher returns and lower risk, as measured by variability of
returns, than a less diversified portfolio.

     Historically, managed futures investments have had very little correlation
to the stock and bond markets. Non-correlated performance is not, however,
negatively correlated performance. Non-correlation means only that the
performance of managed futures likely has no relation to the performance of
stocks and bonds.

     Non-correlation will not provide diversification advantages beyond,
perhaps, lowering a portfolio's overall volatility unless the non-correlated
assets are performing positively. There can be no assurance that the Fund will
perform positively or avoid losses.

MARKET DIVERSIFICATION

     The Index SPC will trade in 40 to 60 or more markets, though not
necessarily in all markets at all times.

     The diversification of the Index SPC permits investors to participate in
markets that would otherwise not be included in their portfolios, thereby both
potentially diversifying risk and increasing profit opportunities.

     The markets traded by the Index SPC may change from time to time.

OPPORTUNITY TO PROFIT IN RISING AS WELL AS IN DECLINING MARKETS

     The Fund may realize positive or negative returns in both rising and
declining markets as futures positions may be established on either the long or
the short side of a market. Unlike short selling in the securities markets,
selling short in futures in anticipation of a drop in price can be accomplished
without additional restrictions or special margin requirements.

     It is potentially advantageous for investors to own investments that can
appreciate during a period of generally declining prices, financial disruption
or economic instability. Investors must realize, however, that the Fund is not
specifically designed to appreciate in declining markets. Rather, it is designed
to substantially track the Index. The Fund will only increase in value if the
portfolio managers' trading systems identify market trends and are able to trade
those trends profitably.

                                       15
<Page>

SMALL MINIMUM INVESTMENT; SMALLER MINIMUM ADDITIONAL INVESTMENT

     The portfolio managers typically manage individual accounts only of
substantial size--$1,000,000 or more. You may gain access to the portfolio
managers for a minimum investment of only $10,000 ($3,000 for an individual
retirement account). You may make additional investments in minimums of only
$2,500.

LIMITED LIABILITY

     If you open an individual futures account, you will be generally liable for
all losses incurred in the account, and may lose substantially more than you
committed to the account. However, as an investor in the Fund, you cannot lose
more than your investment plus undistributed profits.

ADMINISTRATIVE CONVENIENCE

     The general partner is responsible for all aspects of the Fund's operation.
You will receive monthly unaudited and annual audited financial reports as well
as information necessary for you to complete your federal income tax returns.
The approximate daily net asset value per Unit will be available on Bloomberg or
by calling representatives of the general partner at 212-693-7047.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

     The Fund was formed on May 13, 2003 under the laws of the State of
Delaware. To date, its only activities have been preparing for this offering and
accepting capital contributions of $1,000 from the general partner and $1 from
the initial limited partner. The Fund has not begun trading. Therefore, the
financial statement of the Fund included in the prospectus is not indicative of
future operating results. The Fund's future operating results will depend in
large part upon the commodity and financial futures markets in general, the
Index SPC's performance, changes in interests rates and the amount of
subscriptions and redemptions. Because of the nature of these factors and their
interaction, it is impossible to predict future operating results, financial
position and cash flows of the Fund.

     The portfolio managers will make all trading decisions on behalf of the
Index SPC. The general partner will have no control over the operation of the
Index SPC. The Fund's performance results will be reported to you monthly along
with a discussion of the Index SPC's trading activities. As a limited partner,
however, you will not know the Index SPC's actual positions.

                                       16
<Page>

CRITICAL ACCOUNTING POLICIES - VALUATION OF THE INDEX SPC'S POSITIONS

     The general partner believes that the accounting policies that will be most
critical to the Fund's financial condition and results of operations relate to
the valuation of the Index SPC's positions. The majority of the Index SPC's
positions will be exchange-traded futures contracts, which will be valued daily
at settlement prices published by the exchanges. The Index SPC's spot and
forward foreign currency contracts will also be valued at published daily
settlement prices or at dealers' quotes. Swap contracts generally will be valued
by reference to published settlement prices or dealers' quotes in related
markets or other measures of fair value deemed appropriate by the general
partner. The general partner does not believe that the Index SPC will trade
swaps to a significant degree. Thus, the general partner expects that under
normal circumstances substantially all of the Index SPC's assets, and as a
result the Fund's assets, will be valued by objective measures and on a timely
basis.

     *"Worst Monthly Drawdown" is the largest negative monthly rate of return
experienced by a pool.
     **"Worst Peak-to-Valley Drawdown" is the greatest percentage decline in net
asset value experienced by a pool without such net asset value being
subsequently equaled or exceeded. For example, if the value of a pool unit
dropped by 1% in each of January and February, rose 1% in March and dropped
again by 2% in April, a "Peak-to-Valley Drawdown" would be still continuing at
the end of April in the amount of approximately -3%, whereas if the value of the
pool unit has risen by approximately 2% or more in March, the drawdown would
have ended as of the end of February at the -2% level.

THE SUB-INVESTMENT MANAGER

     The actual and pro forma performance record of the Index SPC is set forth
in Capsules B and C below. The Sub-Investment Manager also acts as the
investment manager or commodity pool operator for other privately offered
limited partnerships and as the sponsor of offshore investment vehicles. The
performance results of these other vehicles is not being presented pursuant to
relief under CFTC Regulation 4.7.

     THE INDEX SPC - ACTUAL EXTRACTED PERFORMANCE

     The Index SPC trades pursuant to two different programs. The Fund's assets
will be traded pursuant to the Index SPC's S&P Managed Futures Index Program -
which allocates assets to the 14 constituents of the Index proportional to their
weight in the Index. The Index is rebalanced annually in January to equal
weighting among constituents. The other program traded by the Index Fund is the
S&P Hedge Fund Index which allocates assets to only four managed futures
programs. The Index SPC commenced trading the S&P Hedge Fund Index program on
July 16, 2002. The Index SPC commenced trading the S&P Managed Futures Index
program on December 10, 2002, but made allocations only to 12 of the
constituents. On December 23, 2002, it made allocations to the remaining two
constituents. S&P began calculating the S&P Managed Futures Index values on
January 1, 2003. To present the fairest representation of the Index SPC's
performance, the following capsule (1) excludes the performance related to the
S&P Hedge Fund Index program and (2) aggregates the performance of the 14
portfolios to develop composite figures.

INVESTMENT PROGRAM

     The Fund's investment objective is to seek investment returns that
substantially track the Index. Standard & Poor's has long been recognized
worldwide as a global provider of equity indices. In October 2002, Standard &
Poor's launched the Standard & Poor's Hedge Fund Index. In January 2003,
Standard & Poor's launched the Index, which is an expansion of the managed
futures subset of the Standard & Poor's Hedge Fund Index. Standard & Poor's is
responsible for calculating the Index and publishes Index values on the Standard
& Poor's website: www.standardand poors.com. The Index is rebalanced annually or
as required by Standard & Poor's. Addition or deletion of Index constituents is
at the sole discretion of Standard & Poor's Index Committee. The Index is
designed to offer an investable benchmark that is representative of the managed
futures segment of hedge fund investing. The Index focuses on the systematic,
trend-following trading methodologies that constitute the significant majority
of managed futures investment strategies. Constituents of the Index are
portfolio managers using managed futures strategies.

     The general partner will pursue the Fund's investment objective by
allocating the Fund's assets to the Index SPC. The Index SPC, which is managed
by PlusFunds, allocates its assets to portfolio managers that generally employ a
broad range of systematic trading strategies in the futures markets. Other
markets, such as the interbank foreign exchange market, may be used as well. The
Index SPC is designed to track the Index, and thus to provide investors with
exposure to a broad cross section of systematic managed futures strategies
through a single investment. Investors will have access to a variety of managed
futures strategies without being subject to high minimum requirements that might
otherwise be imposed. The Fund provides investors with access to professionally
selected managers who are considered by Standard & Poor's to be representative
of managed futures trading strategies. These managers may not be otherwise
available to investors. The Fund will not invest in the Index, nor will the
return of the Fund exactly track the performance of the Index. As constituent
allocations change from time to time in the Index as a result of Standard &
Poor's changes in Index composition, the Index SPC likewise intends to adjust
its allocations to reflect the Index composition.

     The Index is designed as a benchmark of the performance of various managed
futures trading strategies. Managed futures trading advisors trade in financial
and commodity markets around the world. Typical investment and trading
instruments used by trading advisors include futures contracts, forward
contracts, options on futures contracts, swaps and other derivative products,
and physical commodities. Trading advisors that follow a systematic approach
tend to take positions based on computer-generated models to identify trades,
determine size of positions and precisely time trades. The trading advisors
represented in the Index follow systematic trading approaches, employing mainly
technical trend-following and pattern recognition trading

                                       26
<Page>

methods. There are no limits on the amount of leverage a trading advisor may use
in connection with its trading strategies.

     The portfolio managers, which will be initially equally weighted within the
Index, are included in the Index are selected based on, among other things,
Standard & Poor's analysis of:

     - the portfolio manager's trading strategy;

     - risk/return characteristics;

     - volatility levels;

     - performance during various time periods and market cycles; and

     - the structure of the portfolio manager's portfolio and the types of
       instruments held.

     Other factors include (1) the portfolio manager's reputation, experience
and training; (2) the portfolio manager's articulation of, and adherence to, the
portfolio manager's stated investment philosophy; (3) the quality and stability
of the portfolio manager's organization, including internal and external
professional staff and (4) the presence and deemed effectiveness of the
portfolio manager's risk management discipline. Portfolio managers are generally
required to have two to three years of performance history to qualify for
inclusion in the Index, and minimum assets under management of $75 million using
the relevant trading strategy.

     The process of constructing the Index begins by identifying a set of
candidate portfolio managers for potential membership by the Standard & Poor's
Index Committee. These candidates include portfolio managers of programs that
actively report data to certain public databases, as well as other portfolio
managers who do not report to the databases but are identified through other
means. From the set of the candidate portfolio managers, those portfolio
managers whose structure, behavior and/or history is, in the opinion of the
Standard & Poor's Index Committee, inconsistent with the institutional
constraints, requirements and the guidelines discussed elsewhere are eliminated.
A portfolio manager's methodology is analyzed for its adherence to its stated
strategy and its relevance to the Index. Historical returns for these programs
are collected from the portfolio managers. The returns are subject to a number
of screens in order to identify a subset of portfolio managers that would
satisfy the selection criteria of the Standard & Poor's Index Committee. In
addition to qualitative information such as portfolio manager
self-classification and the portfolio manager's description of investment
approaches, the Standard & Poor's Index Committee employs advanced statistical
methods in an effort to identify those portfolio managers that are most
representative of managed futures strategies. Portfolio managers that do not
satisfy the minimum correlation criteria are generally not considered.
Statistical analysis techniques are used to group portfolio managers and to
check for internal consistency with the required criteria.

     The Standard & Poor's Index Committee is charged with overseeing the
methodology and operations of the Index and has primary responsibility for the
Index's strategy classifications, composition and methodology. The Standard &
Poor's Index Committee is also responsible for ensuring that the Index maintains
the standards outlined above. The Standard &

                                       27
<Page>

Poor's Index Committee is controlled by representatives, including the
Chairperson, from Standard & Poor's, but may include industry experts from
outside Standard & Poor's.

     The Index is not managed in an effort to achieve specific investment
returns or with regard to the interests of the Fund, the Index SPC or their
investors. The constituents of the Index, a more detailed description of the
Standard & Poor's Managed Futures Index structure, methodology, definitions and
practices prepared by Standard & Poor's, as well as the results for the Index,
are available on the S&P Indices area of www.standardandpoors.com. The contents
of that website are not incorporated by reference into this prospectus.

THE INDEX SPC

     The Index SPC was organized in July 2002 as a Cayman Islands exempted
segregated portfolio company and operates pursuant to Part XIV of the Companies
Law (2002 Revisions).

     Since the Index SPC is designed to achieve returns that substantially track
the Index, portfolio managers generally are selected based on such portfolio
manager's representation in the Index, and allocations among the portfolio
managers are generally made according to a weighting scheme that is designed to
replicate the weighting scheme applied by Standard & Poor's in respect to the
Index. As of the date of this prospectus, the portfolio managers (and the
trading programs they use for the Index) are:

     - Aspect Capital Limited (Aspect Diversified Program);

     - Beach Capital Management Limited (Beach Discretionary Programme);

     - Campbell & Company, Inc. (Financial, Metals & Energy Large Portfolio);

     - Chesapeake Capital Corporation (The Diversified Program);

     - Dunn Capital Management, Inc. (Dunn Combined Financial);

     - Eclipse Capital Management, Inc. (Global Monetary Program);

     - Graham Capital Management, L.P. (Global Diversified Program);

     - Hyman Beck & Company, Inc. (The Global Portfolio);

     - John W. Henry & Company, Inc. (Global Financial & Energy Portfolio);

     - Beacon Management Corporation (USA) (Meka - MV);

     - Millburn Ridgefield Corporation (Diversified Portfolio);

     - Rotella Capital Management, Inc. (The Polaris Program);

     - Willowbridge Associates Inc. (Argo Trading System); and

     - Winton Capital Management Ltd. (Diversified Program).

                                       28
<Page>

     These portfolio managers, and their strategies, are subject to change.

     The Index SPC will adhere to the following investment restrictions, some of
which have more application to securities trading rather than futures trading:

     - No more than 20% of the value of the gross assets of the assets allocated
     to a portfolio manager may be lent to or invested in the securities of any
     one issuer or may be exposed to the creditworthiness or solvency of any one
     counterparty;

     - No more than 40% of the value of the gross assets of the assets allocated
     to a portfolio manager may be invested in any other fund or may be
     allocated to any other manager to manage on a discretionary basis, provided
     that the other fund or manager operates on the principle of risk spreading

     - No more than 20% of the value of the gross assets of the Index SPC may be
     invested in other funds whose principal investment objective includes
     investing in other funds;

     - The portfolios traded by the portfolio managers on behalf of the Index
     SPC may not take legal or management control of the issuer or any of its
     underlying assets; and

     - The portfolio managers must observe the general principle of
     diversification of risk in their derivatives trading

     Except where specified to the contrary, the above restrictions apply as of
the date of the relevant transaction or commitment to invest. Changes in the
investments of the Index SPC will not have to be effected merely because any of
the limits contained in such restrictions would be breached as a result of any
appreciation or depreciation in value, or by reason of the receipt of any right,
bonus or benefit in the nature of capital or of any scheme or arrangement for
amalgamation, reconstruction or exchange or by reason of any other action
affecting every holder of the relevant investment. However, no further relevant
securities will be acquired until the limits are again complied with. In the
event that any of the investment restrictions are inadvertently breached,
PlusFunds will take reasonable steps to rectify the breach.

     The general partner does not intend to invest the Fund's assets directly
other than in the Index SPC, except that the general partner may invest funds
temporarily in U.S. government obligations, money market accounts or other
short-term interest-bearing accounts. The Fund will not borrow money for the
purposes of making investments in the Index SPC. The Fund may borrow money on a
secured or unsecured basis from banks for cash management purposes, and will pay
interest on such borrowed monies. There is no internal limit on the amount that
the Fund may borrow.

     Refco, LLC, an affiliate of the general partner and of the selling agent,
acts as futures broker for the Index SPC and in such capacity provides
execution, clearing and margin services in connection with futures and
commodities trading activities. Refco Capital Markets, also an affiliate of the
general partner and of the selling agent, acts as the dealer for the Index SPC
for currency trading.

     Neither the Fund nor the Index SPC are sponsored, endorsed, sold or
promoted by Standard & Poor's. Standard & Poor's makes no representation or
warranty, express or implied, to investors in the Fund regarding the
advisability of investing in managed futures generally or in the Fund
particularly or the ability of the S&P Managed Futures Index to track the market
performance of managed futures. Standard & Poor's only relationship to PlusFunds
and the Refco Group is the licensing of various trademarks and trade names of
Standard & Poor's and of the Standard & Poor's Managed Futures Index, which is
determined, composed and calculated by Standard & Poor's without regard to
PlusFunds, the Refco Group, the Fund or the Index SPC. Standard & Poor's has no
obligation to take the needs of PlusFunds, the Refco Group, or investors in the
Fund or the Index SPC into consideration in determining, composing or
calculating the Standard & Poor's Managed Futures Index. Standard & Poor's is
not responsible for, and has not participated in, the determination of the
timing of, prices at, or quantities of interests in the Fund or the Index SPC to
be issued. Standard & Poor's has no obligation or liability in connection with
the administration, marketing or trading of the Fund or the Index SPC.

STANDARD & POOR'S HAVE ANY LIABILITY FOR ANY SPECIAL, PUNITIVE, INDIRECT, OR
CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS), EVEN IF NOTIFIED OF THE
POSSIBILITY OF SUCH DAMAGES.

     THE FUND'S INVESTMENT STRATEGIES INVOLVE SUBSTANTIAL RISK. THERE CAN BE NO
ASSURANCE THAT THE INVESTMENT OBJECTIVE OF THE FUND WILL BE ACHIEVED, OR THAT
THE FUND WILL HAVE ANY PROFITS OR WILL NOT EXPERIENCE SUBSTANTIAL LOSSES.

USE OF PROCEEDS

     The general partner expects that the proceeds from the sale of Units, net
of the Fund's organization costs, offering costs and ongoing fees and expenses,
will be invested in the Index SPC as soon as practicable after the receipt of
such proceeds by the Fund.

     The Fund will not lend any of its assets to any person or entity other than
through permitted securities investments, like repurchase agreements. The
general partner will not commingle the property of the Fund with the property of
any other person or entity in violation of law.

                                                  incentive fees, if any, paid to the
                                                  portfolio managers; (2) fees paid to the

                                                  brokerage commissions and other
                                                  transaction-related expenses of the
                                                  Index SPC; and (4) organizational
                                                  expenses, accounting, audit and legal
                                                  expenses, custodial fees and any
                                                  extraordinary expenses of the Index SPC.
                                                  The management fees paid to the
                                                  portfolio managers generally are
                                                  expected to range from 1% to 2.50% per
                                                  annum of the assets allocated to a
                                                  portfolio manager. Each portfolio
                                                  manager also receives an annual
                                                  incentive fee based on the net trading
                                                  gain of the assets allocated to the
                                                  portfolio manager. The incentive fees
                                                  are generally expected to range from 15%
                                                  to 25% of net trading gain.

Third Parties            Ongoing Offering         The Fund will pay its ongoing offering
                         Expenses                 expenses. These expenses are not
                                                  expected in the aggregate to exceed
                                                  0.25% per annum of the month-end net
                                                  asset value of the Fund.

Third Parties            Ordinary Expenses        Paid as incurred, these expenses include
                                                  the legal, audit and other routine
                                                  expenses of the Fund. These costs are
                                                  estimated at an annual rate of 0.15% of
                                                  the Fund's net asset value.
</Table>

MANAGEMENT FEE

     The Fund will pay the general partner a monthly management fee equal to
0.3125% of the Fund's net assets as of the end of each month (a 3.75% annual
rate). From this amount the General Partner will pay the organizational and
initial offering expenses of the Fund. In addition, beginning in the 13th month
following the purchase of any Units, the General Partner will pay to the selling
agents of the Units a monthly trailing commission equal to 0.1875% of the Fund's
month-end Net Assets (a 2.25% annual rate) per Unit multiplied by the number of
Units placed by the selling agent for providing additional services in
connection with the Units. The management fee is calculated and payable as of
the last business day of each month. The management fee is calculated without
reduction of net assets for any distributions or redemptions accrued or payable
as of the date the fees are calculated. The management fee is payable whether or
not the Fund's investment in the Index SPC is profitable.

     The general partner has entered into a sub-investment management agreement
with PlusFunds, the investment manager of the Index SPC, to obtain information
and assistance from PlusFunds to facilitate management of the Fund. The general
partner will compensate PlusFunds directly from the management fee it receives
from the Fund.

                                       32
<Page>

ADMINISTRATIVE FEE

     The Fund will pay the general partner a monthly administrative fee equal to
0.0208% of the Fund's net assets (a 0.25% annual rate). The administrative fee
is calculated and payable as of the last business day of each month. The
administrative fee is calculated without reduction of net assets for any
distributions or redemptions accrued or payable as of the date the fees are
calculated. The administrative fee is payable whether or not the Fund's
investment in the Index SPC is profitable.

     The general partner may enter into a sub-administrator agreement with a
third party, to obtain information and assistance from the sub-administrator to
facilitate administration of the Fund. The general partner will compensate the
sub-administrator directly from the administrative fee it receives from the
Fund. The sub-administrator will serve as the Fund's transfer agent.

UPFRONT SELLING COMMISSION REIMBURSEMENT

     The general partner will pay the selling agents an upfront selling
commission equal to 3% of the subscription amount. The Fund will reimburse the
general partner by paying the general partner an amount equal to 0.06205% of the
Fund's net assets as of the end of each month (a 0.75% annual rate), provided,
however, that the Fund will cease to reimburse the general partner with respect
to any upfront selling commission when the general partner has received the
amount actually paid by the general partner, plus interest.

REDEMPTION FEES

     A redemption fee of 3% of net asset value per Unit applies if you redeem
Units within 12 months of their original purchase. After the 12th month
following purchase of a Unit, no redemption fees apply. The redemption fee will
be paid to the general partner.

FUND'S PRO RATA SHARE OF THE FEES AND EXPENSES OF THE INDEX SPC

     As a limited partner in the Index SPC, the Fund will pay its pro rata share
of the fees and expenses of the Index SPC. The fees and expenses of the Index
SPC include:

     - management fees and incentive fees, if any, paid to the portfolio
       managers;

     - fees paid to the Index SPC's administrator;

     - brokerage commissions and other transaction-related expenses of the
       Index SPC;

     - accounting, audit and legal expenses;

     - organizational expenses;

     - custodial fees of the Index SPC; and

     - any extraordinary expenses of the Index SPC.

                                       33
<Page>

     The management fees paid to the portfolio managers generally are expected
to range from 1% to 2.50% per annum of the assets that they manage and are
payable monthly as of the last day of each month. Each portfolio manager may
also receive an annual incentive fee based on the net trading gain of the assets
that it manages. The incentive fees are determined as of December 31 each year
and on redemptions from the Index SPC other than as of December 31, and are
generally expected to range from 15% to 25% of net trading gain. Net trading
gain is equal to the change in unrealized profit or loss (net of all accrued
brokerage costs) during the period, plus the realized profit or loss on
positions closed during the period (net of all brokerage costs), less any
accrued interest on uninvested cash, minus expenses for the period (excluding
incentive fee, management fee and applicable administration fee), less the
period-to-period loss carryforward, if any.

ONGOING OFFERING COSTS

     The Fund will pay its ongoing offering expenses. These expenses are not
expected in the aggregate to exceed 0.25% per annum of the month-end net asset
value of the Fund.

ORDINARY EXPENSES

     The Fund will pay its own ordinary expenses as incurred. These expenses
include the legal, audit and other routine expenses of the Fund and are
estimated at an annual rate of 0.15% of the Fund's net assets.

EXTRAORDINARY EXPENSES

     The Fund is responsible for any extraordinary charges (E.G., litigation
expenses) incidental to its operation.

CAPS ON FEES

     The Fund expects to pay the fees outlined above. The limited partnership
agreement and/or guidelines of state securities regulators, however, limit the
fees that may be paid by the Fund.

     Aggregate annual fees and expenses based on the Fund's net assets may not
exceed 6% of net assets per year (1/2 of 1% per month). This cap includes
management fees, advisory fees and customary and routine administrative expenses
of the Fund as well as periodic filing and reporting fees but does not cover
incentive fees, commodity brokerage fees, legal and accounting services or
extraordinary expenses.

     Organizational and offering expenses, compensation for sales of Units and
redemption fees may not exceed 15% of aggregate subscriptions to the Fund.

     In addition, the limited partnership agreement prohibits the payment of
management fees to any person who receives brokerage commissions on transactions
for the Fund, as well as the payment by any broker of rebates or give-ups to any
advisor. This provision does not affect the payment of the fees and expenses
described above.

REDEMPTIONS; NET ASSET VALUE

REDEMPTION PROCEDURE

     The Fund is intended as a medium- to long-term investment, which the
general partner construes to mean at least a three to five year period. However,
you may generally redeem Units as of the last business day of any calendar
month, subject to the restrictions and qualifications set forth herein. You must
give at least 10 business days' prior written notice to the general partner of
your intent to redeem, except as provided below.

     The general partner may declare additional redemption dates upon notice to
the limited partners and may, in unusual circumstances, permit some, or all,
limited partners to redeem as of dates other than the end of the month. The
general partner shall declare a special redemption date whenever the Fund
experiences a decline in net asset value per Unit as of the closing of business
on any business day to less than 50% of the net asset value per Unit on the last
month-end valuation date.

     A redemption fee of 3% of net asset value per Unit applies if you redeem
Units within 12 months of their original purchase. For purposes of determining
the existence of an early redemption fee, redemptions will be made on a
first-in, first-out basis. After the 12th month following purchase of a Unit, no
redemption fees apply.

     You may redeem any or all of their Units, but the Fund has the right to
cause you to redeem all of your Units if the net asset value of your Units
remaining after a requested redemption is less than $1,000.

     A form of Request for Redemption is attached as an exhibit to the
prospectus.

     Subject to the qualifications described in the remainder of this paragraph,
all requests for redemption will be honored and payment will be made within 10
business days of the redemption date. The general partner will make arrangements
with selling agents who so request to pay redemptions through crediting limited
partners' customer securities accounts with the selling agents. If, in the
general partner's judgment, additional redemptions would impair the ability of
the Fund to meet its objectives or if a market disruption results in the closing
of financial markets in the United States or abroad and it is impossible or
impracticable to value the Units or liquidate Fund assets, redemptions may be
suspended or payment of redemption proceeds may be delayed. In addition, the
right of a limited partner to receive a redemption payment further depends on
the Fund's ability to obtain the necessary funds by redeeming its investment in
the Index SPC, which is subject to certain limits. Under these limits,
redemptions of interests in the Index SPC by the Fund as of any particular
redemption date cannot exceed 20% of the Fund's investment in the Index SPC as
of that date unless the Index SPC has received at least 15 business days' notice
prior to a redemption date. The general partner will notify the limited partners
in writing if redemptions are suspended.

     Units purchased by the general partner, other than Units representing its
required investment in the Fund, may be redeemed on the same terms as any other
Units.

                                       35
<Page>

     The general partner may require you to redeem all or a portion of your
Units if the general partner believes it is desirable for the protection of the
Fund.

NET ASSET VALUE

     Net assets means the total assets, less total liabilities, of the Fund
determined on the basis of generally accepted accounting principles. Net assets
shall include any unrealized profits or losses on open positions, and any fee or
expense accruing to the Fund.

CONFLICTS OF INTEREST

GENERAL

     The general partner has not established any formal procedures to resolve
the conflicts of interest described below, therefore, you will be dependent on
the good faith of, and the legal and fiduciary obligations imposed on, the
respective parties subject to the conflicts to resolve them equitably. Although
the general partner will attempt to monitor and resolve these conflicts in good
faith, they may result in losses for the Fund.

THE GENERAL PARTNER

     One of the managers of the general partner is also a manager of the selling
agent, which may be deemed a conflict of interest in that the selling agent
agreement has not been negotiated on an arm's-length basis, and the Fund is less
likely to terminate the selling agent than would otherwise be the case if the
selling agent were not an affiliate of the general partner.

     The general partner has a conflict between its role as a general partner in
limiting expenses and the benefits it will receive from the different fees and
compensation paid to it (which fees and compensation were established without
arm's-length negotiation).

   The general partner, in its sole discretion, determines whether any
distributions will be made. To the extent that profits are retained by the Fund
rather than distributed, net assets and therefore the amount of fees paid to the
general partner and the general partner's affiliate, the selling agent, will
increase.

THE SELLING AGENTS

     The selling agents receive substantial selling commissions on the sale of
Units. Consequently, the selling agents have a conflict of interest in advising
their clients whether to invest in the Units.

     The selling agents receive trailing commissions based on Units sold by them
that remain outstanding longer than 12 months. Consequently, the selling agents
have a disincentive to advise clients to redeem their Units even when doing may
be in clients' best interests.

                                       36
<Page>

OTHER BUSINESS ACTIVITIES, PROPRIETARY TRADING AND TRADING FOR OTHER ACCOUNTS

     Subject to their fiduciary obligations to the Fund, the general partner,
PlusFunds and each of their respective employees or affiliates may conduct any
other business, including any business within the investment industry. Without
limiting the generality of the foregoing, the general partner, PlusFunds and
their respective employees or affiliates may act as adviser or investment
manager for others, may manage funds or capital for others, may have, make and
maintain investments in their own names or through other entities, may serve as
a consultant, partner or stockholder of one or more investment funds,
partnerships, securities firms or advisory firms and may act as a director,
officer and/or employee of any corporation, a trustee of any trust, an executor
or administrator of any estate or an administrative official of any other
business entity.

     Moreover, the general partner and PlusFunds will not be required to give
the Fund or the Index SPC preference with respect to any investment opportunity,
refrain from any other activity or disgorge any profit from any activity or to
devote all or any specific amount of their respective time and effort to the
Fund or the Index SPC and their affairs.

     Furthermore, the general partner and PlusFunds will transact business
independently of the Fund and the Index SPC and may purchase and sell, for their
own accounts or for other accounts under their management, some of the vehicles
or instruments in which the Fund invests directly or indirectly. These
activities, and other aspects of the relationship between the general partner,
PlusFunds and their respective employees and affiliates, on the one hand, and
the Fund and the Index SPC, on the other hand, could create conflicts of
interest between any such person and the Fund or the Index SPC.

     The general partner and its employees and affiliates may establish in the
future additional investment funds with the same objective and strategy as the
Fund, in which event the general partner will allocate investments among the
Fund and additional investment funds on whatever basis it considers appropriate
or desirable.

FIDUCIARY DUTY AND REMEDIES

     In evaluating the foregoing conflicts of interest, a prospective investor
should be aware that the general partner, has a responsibility to limited
partners to exercise good faith and fairness in all dealings affecting the Fund.
If you believe that the general partner has violated its fiduciary duty to the
limited partners, you may seek legal relief individually or on behalf of the
Fund under applicable laws to recover damages from or require an accounting by
the general partner. The limited partnership agreement of the Fund is governed
by Delaware law and any breach of the general partner's fiduciary duty under the
limited partnership agreement will generally be governed by Delaware law. The
limited partnership agreement does not limit fiduciary obligations under
Delaware or common law. The general partner may, however, assert as a defense to
claims of breach of fiduciary duty that the conflicts of interest and fees
payable to the general partner have been disclosed to you in the prospectus.

THE FUND'S LIMITED PARTNERSHIP AGREEMENT

     The following summary briefly describes the material terms of the limited
partnership agreement. You should carefully review the limited partnership
agreement attached hereto as Exhibit A and consult with your own advisors
concerning the implications to you of investing in a Delaware limited
partnership.

PRINCIPAL OFFICE; LOCATION OF RECORDS

     The Fund is organized under the Delaware Revised Uniform Limited
Partnership Act. The Fund is administered by the general partner. The address of
both the Fund and the general partner is 550 W. Jackson, Suite 1300, Chicago,
Illinois 60604; telephone: (312) 788-2000. The records of the Fund, including a
list of the limited partners and their addresses, is located at the foregoing
address, and available for inspection and copying by limited partners as
provided in the limited partnership agreement.

MANAGEMENT OF FUND AFFAIRS; VOTING BY LIMITED PARTNERS

     You will not take any part in the management or control and will have no
voice in the operations of the Fund or its business.

     The limited partnership agreement may be amended by the general partner and
limited partners owning more than 50% of the outstanding Units agreement. The
general partner may amend the limited partnership agreement without the approval
of the limited partners in order to (1) clarify inaccuracies or ambiguities, (2)
make changes required by any federal or state agency or by law, (3) effect the
intent of the allocation provisions of the Partnership Agreement, (4) qualify or
maintain the qualification of the Fund in any state, (5) make changes to protect
the Fund's partnership status for federal income tax purposes and to prevent the
Fund from being treated as an investment company or the Fund's assets from being
considered plan asset for ERISA purposes or (6) make other changes the general
partner deems advisable so long as they are not adverse to limited partners.

     Although the Fund will not hold any regular, or annual, meetings of the
limited partners, upon receipt of a written proposal signed by the owners of at
least 10% of the outstanding Units that a meeting be called, the general partner
will call a meeting of the Fund. At the meeting, limited partners owning a
majority of the outstanding Units may vote to:

     -    amend the limited partnership agreement without the consent of the
general partner, provided, that the consent of the general partner is required
for any amendment that modifies the compensation or distributions to which the
general partner is entitled or that affects the general partner's duties;

     -    dissolve the Fund;

     -    remove and replace the general partner;

     -    admit a new general partner in the event the current general partner
withdraws; and

                                       38
<Page>

     -    terminate any contract with the general partner or its affiliates
without penalty upon 60 days' notice.

POSSIBLE REPAYMENT OF DISTRIBUTIONS RECEIVED BY LIMITED PARTNERS;
INDEMNIFICATION OF THE FUND BY LIMITED PARTNERS

     The Units are limited liability investments; you may not lose more than the
amount you invest plus any profits recognized on your investment. However, you
could be required, as a matter of bankruptcy law, to return to the Fund's estate
any distribution which you received at a time when the Fund was in fact
insolvent or in violation of the limited partnership agreement. In addition,
although the general partner is not aware of this provision ever having been
invoked in the case of any public futures fund, limited partners agree in the
limited partnership agreement that they will indemnify the Fund for any harm
suffered by it as a result of limited partners' actions, obligations or
liabilities unrelated to the business of the Fund.

INDEMNIFICATION AND STANDARD OF LIABILITY

     The general partner and some of its affiliates may not be liable to the
Fund or any limited partner for errors in judgment or other acts or omissions
not amounting to misconduct or negligence as a consequence of the
indemnification and exculpatory provisions provided in the limited partnership
agreement. As a result, you may have more limited rights of action than you
would absent those provisions.

     The general partner and its affiliates shall not have any liability to the
Fund or to any limited partner for any loss suffered by the Fund which arises
out of any action or inaction of the general partner or any affiliate if the
general partner or its affiliates, in good faith, determined that such course of
conduct was in the best interests of the Fund, the general partner or its
affiliates were performing services for the Fund and such course of conduct did
not constitute negligence or misconduct.

     The Fund has agreed to indemnify the general partner and its affiliates
against claims, losses or liabilities based on their conduct relating to the
Fund, provided that the general partner or its affiliates, in good faith,
determined the course of action was in the best interests of the Fund, the
general partner or its affiliates were performing services for the Fund and the
conduct resulting in the claims, losses or liabilities for which indemnity is
sought did not constitute negligence or misconduct.

     The limited partnership agreement provides that the general partner, its
affiliates and any person acting as a broker-dealer shall not be indemnified 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, (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 a particular indemnitee and finds that
indemnification of the settlement and related costs should be made.

                                       39

TRANSFERS OF UNITS RESTRICTED

     Subject to compliance with applicable securities laws, you may assign your
Units upon 15 days' prior written notice to the Fund and the general partner. No
assignment will be effective in respect of the Fund or the general partner until
the first business day of the month following the month in which the notice is
received. An assignee may become a substituted limited partner only with the
consent of the general partner (which consent will be withheld only in the event
that such transfer could give rise to negative legal or tax consequences) and
upon execution and delivery of an instrument of transfer in form and substance
satisfactory to the general partner.

     There are no certificates for the Units. Transfers of Units are reflected
on the books and records of the Fund. Transferors and transferees of Units will
each receive notification from the general partner to the effect that such
transfers have been duly reflected as notified to the general partner.

REPORTS TO LIMITED PARTNERS

     The general partner will provide you with monthly and annual reports in
compliance with CFTC requirements. The general partner will also distribute the
tax information related to the Fund necessary for the preparation of your annual
federal income tax returns.

     The general partner will notify all limited partners within seven business
days of the occurrence of any of the following:

     -    any decline in the net asset value per Unit to less than 50% of such
net asset value as of the previous month-end valuation date; and

     -    any other material change affecting the compensation of any party.

     Any such notifications shall include a description of your voting and
redemption rights.

DISSOLUTION AND TERMINATION OF THE FUND

     The Fund will be terminated and dissolved upon the first to occur of:

     - limited partners owning more than 50% of the outstanding Units vote to
dissolve the Fund;

     - the general partner ceases to be general partner and no new general
partner is appointed; or

     - the continued existence of the Fund becomes unlawful.

FEDERAL INCOME TAX ASPECTS

     The following summarizes the material U.S. federal income tax consequences
to individual investors in the Fund. The Fund has obtained an opinion of Mayer,
Brown, Rowe &

                                       40
<Page>

Maw, LLP, counsel to the general partner, that the summary below, to the
extent it constitutes matters of law or legal consequences, correctly
describes the material U.S. federal income tax consequences as of the date
hereof to the Fund and to a U.S. individual who invests in the Fund. The
summary is based on current U.S. federal income tax law, which is subject to
change. Mayer, Brown, Rowe & Maw LLP's opinion is subject to certain
conditions stated therein and represents only its legal judgment and does not
bind the Internal Revenue Service or the courts. No ruling has been or will
be sought from the Internal Revenue Service as to any matters discussed
below. Certain tax consequences discussed below may vary in their application
to each limited partner depending on that limited partner's particular
circumstances, and the summary below therefore is not intended to be a
substitute for professional tax advice. You should consult with your own
professional tax advisor concerning the U.S. federal, state and local tax
consequences of investing in the Fund.

THE FUND'S PARTNERSHIP TAX STATUS

     The Fund will be treated as a partnership and, assuming that the Fund
does not elect to be taxed as a corporation and that substantially all of the
gross income of the Fund in each of its taxable years will constitute
"qualifying income" within the meaning of Section 7704(d) of the Internal
Revenue Code of 1986, as amended, referred to as the Code, it will not be
treated as a "publicly traded partnership". Accordingly, the Fund will not
pay any federal income tax.

TAXATION OF LIMITED PARTNERS ON PROFITS AND LOSSES OF THE FUND

     Each limited partner (other than foreign limited partners, discussed below
and tax-exempt investors) must pay tax on his share of the Fund's annual income
and gains, if any, even if the Fund does not make any cash distributions.

     The Fund generally allocates the Fund's gains and losses equally to each
Unit. However, a limited partner who redeems any Units will be allocated his
share of the Fund's gains and losses in order that the amount of cash a limited
partner receives for a redeemed Unit will generally equal the limited partner's
adjusted tax basis in the redeemed Unit. A limited partner's adjusted tax basis
in a redeemed Unit generally equals the amount paid for the Unit, increased by
income or gains allocated to the Unit and decreased (but not below zero) by
distributions, deductions and losses allocated to the Unit.

FUND LOSSES BY LIMITED PARTNERS

     A limited partner may deduct Fund losses only to the extent of his adjusted
tax basis in his Units. However, a limited partner subject to "at-risk"
limitations (generally, non-corporate taxpayers and closely-held corporations)
can only deduct losses to the extent the limited partner is "at-risk." The
"at-risk" amount is similar to adjusted tax basis, except that it does not
include any amount borrowed on a nonrecourse basis or from someone with an
interest in the Fund.

"PASSIVE-ACTIVITY LOSS RULES" AND ITS EFFECT ON THE TREATMENT OF INCOME AND LOSS

     The trading activities of the Fund are not a "passive activity."
Accordingly, a limited partner can deduct Fund losses from taxable income
(subject to some limitations, such as the

                                       41
<Page>

limitation on deductibility of capital losses, discussed below). However, a
limited partner cannot offset losses from "passive activities" against Fund
gains.

CASH DISTRIBUTIONS AND UNIT REDEMPTIONS

     A limited partner who receives cash from the Fund, either through a
distribution or a partial redemption, will not pay tax on that cash until his
adjusted tax basis in the Units is reduced to zero. A limited partner who
receives cash upon the complete redemption of Units will recognize gain or loss
for federal income tax purposes. The gain or loss will generally equal the
difference between the amount of cash received and the limited partner's
adjusted tax basis for his Units.

GAIN OR LOSS ON SECTION 1256 CONTRACTS AND NON-SECTION 1256 CONTRACTS

     The Code provides specific rules for "Section 1256 Contracts". Section 1256
contracts include certain futures and forward contracts as well as some stock
index option contracts traded on United States exchanges. For tax purposes,
Section 1256 contracts that remain open at year end are marked-to-market and
treated as if the position were closed at year end. The gain or loss on Section
1256 contracts is characterized as 60% long-term capital gain or loss and 40%
short-term capital gain or loss regardless of how long the position was open.

     Non-Section 1256 contracts include Code Section 988 transactions, I.E.,
transactions in which the amount paid or received is denominated by reference to
a foreign currency. In general, gain or loss on Code Section 988 transactions is
characterized as ordinary income or loss. However, the Fund plans to make an
election to treat gain or loss on Non-Section 1256 contracts, such as foreign
futures contracts, some foreign currency forward contracts and non-equity
options on foreign currencies, as capital gain or loss.

TAX ON CAPITAL GAINS AND LOSSES

     A non-corporate limited partner's long-term capital gains--net gain on
capital assets held more than one year and 60% of the gain on Section 1256
contracts--are taxed at a maximum rate of 15% for sales or exchanges occurring
after May 5, 2003 and prior to January 1, 2009 (and 20% for sales or exchanges
occurring thereafter). Short-term capital gains--net gain on capital assets held
one year or less and 40% of the gain on Section 1256 contracts--are subject to
tax at the same rates as ordinary income.

     Individual taxpayers can deduct capital losses only to the extent of their
capital gains plus $3,000. Accordingly, the Fund could suffer significant losses
and a limited partner could still be required to pay taxes on his share of the
Fund's interest income. Capital losses generally may not be carried back to
offset capital gains in prior years, but can be carried forward indefinitely.

     An individual taxpayer can carry back net capital losses on Section 1256
contracts three years to offset earlier gains on Section 1256 contracts. To the
extent the taxpayer cannot offset past Section 1256 contract gains, he can carry
forward such losses indefinitely as losses on Section 1256 contracts.

                                       42

LIMITED DEDUCTION FOR CERTAIN EXPENSES

     Individual taxpayers are subject to material limitations on their ability
to deduct investment advisory expenses and other expenses of producing income.
The general partner intends to treat these items as ordinary business
deductions, or income allocations not subject to the material deductibility
limitations that apply to investment advisory expenses. However, the IRS could
take a different position. The IRS could contend that the ordinary expenses of
the Fund should be recharacterized as investment advisory expenses or,
alternatively, capitalized. If these items were treated as investment advisory
expenses or were capitalized, individual taxpayers would have additional tax
liability, and if recharacterized as investment advisory fees, would be subject
to limited deductibility. See also "--Syndication Expenses," below.

INTEREST INCOME

     Interest received by the Fund is taxed as ordinary income. Net capital
losses can offset ordinary income only to the extent of $3,000 per year. See
"--Tax on Capital Gains and Losses," above.

SYNDICATION EXPENSES

     Neither the Fund nor any limited partner is entitled to any deduction for
syndication expenses (I.E., expenses incurred in issuing and marketing the
Fund), nor can these expenses be amortized by the Fund or any limited partner
even though the payment of such expenses reduces net asset value.

     The general partner has paid or will pay all organization and offering
costs from its own funds and will be reimbursed by the Fund. However, the IRS
could take the position that a portion of the fees paid by the Fund to the
general partner constitutes non-deductible syndication expenses.

INVESTMENT INTEREST DEDUCTIBILITY LIMITATIONS

     Individual taxpayers can deduct "investment interest"--interest on
indebtedness allocable to property held for investment--only to the extent that
it does not exceed net investment income. Net investment income does not include
some net capital gains. A taxpayer can elect to include some net capital gain in
investment income if he forgoes the benefit of the reduced capital gains rate.

IRS AUDITS OF THE FUND AND ITS LIMITED PARTNERS

     The IRS audits Fund-related items at the Fund level rather than at the
limited partner level. The general partner acts as "tax matters partner" with
the authority to determine the Fund's responses to an audit. If an audit results
in an adjustment, all limited partners may be required to pay additional taxes,
interest, and penalties.

     The IRS recently promulgated final Treasury Regulation Section 1.6011-4
which provides that if certain "reportable transactions" occur, which include a
transaction resulting in, or that is reasonably expected to result in, a loss
(unreduced by any gains) under Code Section

                                       43
<Page>

165 of at least $2 million in any single year or $4 million in any combination
of two taxable years for a partnership such as the Fund or $50,000 in any single
year for individuals or trusts, whether the loss flows through from a
partnership, if the loss arises with respect to a Code Section 988 transaction
(as defined in Code Section 988(c)(1) relating to foreign currency
transactions), then an investor in the partnership must file an IRS Form 8886
"Reportable Transaction Disclosure Statement" and attach it to the investor's
Federal income tax return for each taxable year for which the taxpayer's Federal
income tax liability is affected by the taxpayer's participation in the
transaction. Certain other filing requirements for IRS Form 8886 may apply to
certain taxpayers. These rules apply to transactions entered into, or interests
acquired therein, on or after February 28, 2003, and at the taxpayer's election
may be relied upon for transactions entered into on or after January 1, 2003,
and before February 28, 2003 in lieu of generally more stringent rules for that
period. This IRS Form 8886 has not yet been released by the Service. Pursuant to
Revenue Procedure 2003-24, the Service generally excepts from this rule the
positions in which the Fund expects it normally will be indirectly investing in,
E.G., Section 1256 contracts and assets with a "cost" tax basis. If an election
has not been made to treat currency gains and losses as capital gains and
losses, ordinary currency losses are not excepted from the reporting rules, nor
are assets which have been part of a straddle under 1092(c), excluding a mixed
straddle under Treasury Regulation Section 1.1092(b)-4T. The Fund believes that
the limited partners should not be subject to these reporting rules, but that no
assurance can be made in this respect because the inapplicability of the rule
depends on the investments and elections made by the Index SPC and its
portfolios. Treasury Regulation Section 1.6011-4 also includes within reportable
transactions those transactions which have a significant book-tax-difference.
This reporting requirement applies to SEC registered funds, and to non-SEC
registered funds with gross United States assets of $250 million or more.
Revenue Procedure 2003-25 excepts from these rules items resulting solely from
(a) the use of a mark-to-market method of accounting for book purposes but not
tax purposes, (b) the use of a mark-to-market method of accounting for tax
purposes but not for book purposes, or (c) in the case of a taxpayer who uses
mark-to-market accounting for both book purposes and tax purposes, the use of
different methodologies for book purposes and tax purposes. It is expected that
the investments made by the Fund will satisfy this exception, but no assurance
can be given in this matter as the matters relevant for the exceptions are
determined at the Index SPC level.

     In addition, the Service recently promulgated Treasury Regulation Section
301.6112-1 which in general could require that a list be maintained by the
general partner containing the identity of each investor in the Fund and such
other information as required by regulations issued by the Treasury Department
if the Fund directly or through the Index SPC enters into a transaction which
the general partner knows or reasonably expects will be a reportable transaction
of the type described in the previous paragraph. Such list would have to be made
available to the Service upon request. The Fund does not expect to have to
maintain such a list because, as stated in the prior paragraph, it does not
expect these will be reportable transactions, but as further stated in the prior
paragraph, no assurance can be given that this will be the case.

TAXATION OF FOREIGN INVESTORS

     A limited partner who is a non-resident alien individual, foreign
corporation, foreign partnership, foreign fund or foreign estate generally is
not subject to taxation by the United States on capital gains from commodity
trading, provided that the foreign limited partner (in the

                                       44
<Page>

case of an individual) does not spend more than 182 days in the United States
during his taxable year, and provided further, that the foreign limited partner
is not engaged in a trade or business within the United States during a taxable
year to which income, gain, or loss of the Fund is treated as "effectively
connected." An investment in the Fund should not, by itself, cause a foreign
limited partner to be engaged in a trade or business within the United States
for the foregoing purposes, assuming that the trading activities of the Fund
continue to be conducted as described in this prospectus. In the event that the
Fund were found to be engaged in a United States trade or business, a foreign
limited partner would be required to file a United States federal income tax
return for such year and pay tax at full United States rates. In the case of a
foreign limited partner which is a foreign corporation, an additional 30%
"branch profits" tax might be imposed. Furthermore, in such event the Fund would
be required to withhold taxes from the income or gain allocable to such a
limited partner under Code Section 1446.

     Portfolio interest income (other than so-called "contingent interest")
allocable to a foreign limited partner is likewise not subject to United States
federal income tax withholding, provided that the foreign limited partner is not
engaged in a trade or business within the United States and provides the Fund
with an IRS Form W-8BEN or other applicable form. Similarly, a foreign limited
partner's allocable share of interest on U.S. bank deposits, certificates of
deposit and discount obligations with maturities (from original issue) of 183
days or less is not subject to United States federal income tax withholding.
Generally, other interest from United States sources (including original issue
discount) paid to the Fund and allocable to foreign limited partners will be
subject to United States federal income tax withholding at a statutory rate of
30% (subject to applicable treaty reductions).

TAX-EXEMPT U.S. LIMITED PARTNERS

     Tax-exempt U.S. limited partners will not be required to pay tax on their
share of income or gains of the Fund, so long as the limited partner does not
use borrowed funds in connection with its purchase of Units.

STATE AND OTHER TAXES

     In addition to the federal income tax consequences described above, the
Fund and the limited partners may be subject to various state and other taxes.

INVESTMENT IN INDEX SPC

     The Fund will invest in the Index SPC which will hold various positions
in securities, commodities and financial futures. The Fund has been informed
that, for U.S. federal income tax purposes, the Index SPC consists of
multiple portfolios that have elected to be treated as partnerships.
Accordingly, in this summary of certain tax consequences to limited partners,
references to the Fund generally should be read to include also references to
the Index SPC and its portfolios. In general, the Fund will be allocated its
distributive share of items of income, gain, loss, deduction and credit with
respect to such partnerships (the Index SPC portfolios) in which it invests,
and the limited partners in turn will be allocated their share of such items.
The character of such items to the limited partners generally will be the
same as if such item were realized directly by the Fund, but elections and
determinations available to the partnerships in which the Fund

                                       45
<Page>

invests may affect the timing and/or character of income realized by the Fund
and in turn realized by the limited partners. For example, if a partnership (an
Index SPC portfolio) in which the Fund invests holds foreign currency positions
subject to Code Section 988, the gain or loss on such positions will be ordinary
income or loss to the limited partners unless that partnership has made an
election under Code Section 988 to treat the gain or loss as capital gain or
loss. Also, if a partnership in which the Fund invests borrows to finance
positions (including purchasing securities on margin), this will cause part or
all of the income from such positions allocable to a limited partner which is a
tax-exempt organization to be unrelated business taxable income in the same
manner as if the Fund borrowed to finance such positions directly. In addition,
the Fund will report its expenses from an underlying partnership (an Index SPC
portfolio) as Code Section 162 or Code Section 212 deductions or otherwise
consistent with the manner in which such partnership reports such expenses. The
status of the Index SPC portfolios as partnerships for United States federal
income tax purposes depends on their satisfying certain conditions, E.G., the
conditions set forth above under "The Fund's Partnership Tax Status". The Fund
expects that the Index SPC portfolios will satisfy such conditions, but cannot
assure this.

     PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR TAX ADVISORS BEFORE
DECIDING WHETHER TO INVEST.

PURCHASES BY EMPLOYEE BENEFIT PLANS

GENERAL

     The following section is a summary of the material consequences under the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and the
Code, which a fiduciary of an "employee benefit plan" as defined in ERISA or of
a "plan" as defined in Section 4975 of the Code (and including for this purpose,
any entity deemed to hold plan assets) should consider before deciding to invest
any of such plan's assets in the Fund (such "employee benefit plans", "plans"
and other entities holding plan assets being referred to herein as "Plans").

     ERISA and Section 4975 of the Code together impose restrictions on plans or
accounts of various types which provide retirement benefits or welfare benefits
to an individual or to an employer's employees and their beneficiaries. These
plans and accounts include, but are not limited to, corporate pension and profit
sharing plans, "simplified employee pension plans," KEOGH plans for
self-employed individuals (including partners), individual retirement accounts
described in Section 408 of the Code and medical benefit plans as well as
entities deemed to hold the assets of these plans and accounts, but generally do
not include any plan maintained by a church or by a state or local government
(however, government plans may be subject to rules similar to ERISA and the
Code).

     In addition, ERISA requires that each plan fiduciary must give appropriate
consideration to the facts and circumstances that are relevant to an investment
in the Fund, including the role that an investment in the Fund plays in the
Plan's overall investment portfolio. Therefore, fiduciaries of ERISA plans,
before deciding to invest in the Fund, must be satisfied that investment in the
Fund is a prudent investment for the Plan, that the investments of the Plan,
including the investment in the Fund, are diversified so as to minimize the risk
of large losses and that an investment in the Fund complies with the terms of
the Plan and the related Fund.

                                       46
<Page>

"PLAN ASSETS"

     The purchase of Units by a Plan raises the issue of whether that purchase
will cause, for purposes of Title I of ERISA and subject to Section 4975 of the
Code, the underlying assets of the Fund to be considered to constitute assets of
such Plan. A regulation issued under ERISA (the "ERISA Regulation") contains
rules for determining when an investment by a Plan in an equity interest of an
entity will result in the underlying assets of such entity being considered
assets of such Plan for purposes of ERISA and Section 4975 of the Code (I.E.,
"plan assets"). Those rules provide that assets of an entity will not be
considered assets of a Plan which purchases an equity interest in the entity if
certain exceptions apply, including an exception applicable if the equity
interest purchased is a "publicly-offered security." A publicly-offered security
is a security that is:

     -    freely transferable;

     -    part of a class of securities that is owned by 100 or more investors
independent of the issuer and of one another by the conclusion of the offering;
and

     -    either is (a) part of a class of securities registered under section
12(b) or 12(g) of the Securities Exchange Act of 1934, or (b) sold to the Plan
as part of an offering of securities to the public pursuant to an effective
registration statement under the Securities Act of 1933, if the class of
securities of which the security is a part is registered under the Securities
Exchange Act of 1934 within 120 days, or such later time as may be allowed by
the Securities and Exchange Commission, after the end of the fiscal year of the
issuer during which the offering of the securities to the public occurred.

     The Units are expected to qualify as a "publicly-offered security" pursuant
to the foregoing rules.

INELIGIBLE PURCHASERS

     Units may not be purchased with the assets of a Plan if the general
partner, the Fund, any selling agent, any clearing broker, or any of their
respective affiliates or any of their respective agents or employees: (1) has
investment discretion with respect to the investment of the assets of such Plan
to be invested in the Units; (2) 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 the advice will serve as a
primary basis for investment decisions with respect to the Plan assets and that
the advice will be based on the particular investment needs of the Plan; or (3)
is an employer maintaining or contributing to the Plan, except as is otherwise
permissible under ERISA and Section 4975 of the Code. A party that is described
in clause (1) or (2) of the preceding sentence is a fiduciary under ERISA and
the Code with respect to the Plan, and any such purchase might result in a
"prohibited transaction" under ERISA and the Code.

     Except as otherwise set forth, the foregoing statements regarding the
consequences under ERISA and the Code of an investment in the Fund are based on
the provisions of the Code and ERISA as currently in effect, and the existing
administrative and judicial interpretations thereunder. No assurance can be
given that administrative, judicial or legislative changes will not occur that
will not make the foregoing statements incorrect or incomplete.

     ACCEPTANCE OF SUBSCRIPTIONS ON BEHALF OF PLANS IS IN NO RESPECT A
REPRESENTATION BY THE FUND, THE GENERAL PARTNER, ANY SELLING AGENT OR ANY OTHER
PARTY RELATED TO THE FUND THAT THIS INVESTMENT MEETS SOME OR ALL OF THE RELEVANT
LEGAL REQUIREMENTS WITH RESPECT TO INVESTMENTS BY ANY PARTICULAR PLAN OR THAT
THIS INVESTMENT IS APPROPRIATE FOR ANY PARTICULAR PLAN. THE PERSON WITH
INVESTMENT DISCRETION SHOULD CONSULT WITH HIS OR HER FINANCIAL AND LEGAL
ADVISORS AS TO THE PROPRIETY OF AN INVESTMENT IN THE FUND IN LIGHT OF THE
CIRCUMSTANCES OF THE PARTICULAR PLAN AND CURRENT TAX LAW.

PLAN OF DISTRIBUTION

SUBSCRIPTION PROCEDURE

     The Units are offered on a "best efforts" basis without any firm
underwriting commitment through selling agents including, but not limited to,
Refco Securities, LLC. During the initial offering period, you may purchase the
Fund's Units at $1,000 per Unit. After the initial offering period, you may
purchase Units at net asset value as of the first business day of each calendar
month. The general partner may from time to time cause the Fund to issue Units
at intra-month closings. The minimum initial investment is $10,000, $3,000 for
an individual retirement account. Additional subscriptions by existing limited
partners are permitted in $2,500 minimums. Units are sold in fractions
calculated up to three decimal places.

     In order to purchase Units, you must complete, sign and deliver to a
selling agent an original of the Subscription Agreement and Power of Attorney
Signature Page which accompanies this prospectus, together with a check for the
amount of your subscription. Checks should be made payable to "S&P MANAGED
FUTURES INDEX FUND, LP" Subscription proceeds will be deposited in an account in
the Fund's name at Fifth Third Bank, pending investment in the Fund. Instead of
delivering a check you may wire transfer the amount of your subscription
according to the wire transfer instructions included in the Subscription
Agreement.

     Clients of some selling agents may make subscription payments by
authorizing the selling agents to debit their customer securities account for
the amount of the subscription. When a subscriber authorizes a debit, the
subscriber will be required to have the amount of his or her subscription
payment on deposit in his or her account on a settlement date specified by the
selling agent. The selling agent will debit the account and transmit the debited
funds directly to the Fund's escrow account (during the initial offering period)
or the Fund's bank account (following the initial offering period) via check or
wire transfer made payable to "S&P MANAGED FUTURES INDEX FUND, LP" The
settlement date specified by the selling agents shall be no later than three
business days following notification by the general partner of the acceptance of
an investor's subscription and no later than the termination of the monthly
offering period.

     The general partner will make every reasonable effort to determine the
eligibility of prospective limited partners in the Fund through information
received on the Subscription Agreement. Generally, the general partner must
receive subscription documents at least five

                                       48
<Page>

business days (and cleared funds to purchase the Units at least three business
days) before the end of a month for them to be accepted as of the first day of
the immediately following month.

     The Fund will receive the interest earned on subscriptions held in its bank
account pending investment in the Fund.

     There are no fees applicable to subscriptions held pending investment in
the Fund.

     Subscriptions, if rejected, will be returned to investors, together with
any interest accrued thereon, promptly following the end of the month in which
the subscription was rejected or sooner if practicable.

     Subscriptions are final and binding on a subscriber as of the close of
business on the fifth business day following the subscriber's receipt of a final
prospectus.

ANTI-MONEY LAUNDERING DISCLOSURES

     In order to comply with laws and regulations aimed at the prevention of
money laundering and prohibiting transactions with certain countries,
organizations and individuals, the Fund may request such information as it
reasonably believes is necessary to verify the identity of an investor or a
prospective investor and to determine whether an investor is permitted to be an
investor in the Fund under these laws and regulations. In the event of delay or
failure by an investor or a prospective investor to produce any information
required by the Fund for these purposes, the Fund may require mandatory
redemption of the investor's Units, and may refuse to accept the subscription of
a prospective investor. Likewise, after reviewing the information provided, it
is possible that the Fund may determine to redeem an investor's Units or refuse
to accept a prospective investor's subscription. In certain circumstances, the
Fund may be required to provide information about investors to regulatory
authorities and to take any further action as may be required. Neither the Fund
nor the general partner will be liable for any loss or injury to an investor or
prospective investor that may occur as a result of disclosing such information
or refusing or redeeming Units.

THE SELLING AGENTS

     Refco Securities, LLC has been selected as a selling agent for the Fund.
Refco Securities, LLC and the Fund's other selling agents will receive from the
general partner an upfront selling commission equal to 3% of the purchase price
per Unit at the time that the Unit is sold, and their representatives who sell
Units shall receive a portion of the 3% commission. No selling commissions will
be paid from the proceeds of subscriptions. However, the Fund will reimburse the
general partner with respect to the upfront selling commission by paying the
general partner an amount equal to 0.0625% of the Fund's net assets as of the
end of each month (a 0.75% annual rate), provided, however, that the Fund will
cease to reimburse the general partner with respect to any upfront selling
commission when the general partner has received the amount actually paid by the
general partner, plus interest.

     Beginning with the 13th month following the closing on the purchase of a
Unit, the general partner will pay from its management fee to the selling agent
who sold the Unit ongoing "trailing commissions" at 0.1875% (a 2.25% annual
rate) of the month-end net asset value of the

                                       49
<Page>

Unit -- provided, that CFTC-qualified registered representatives of the selling
agent have satisfied applicable proficiency requirements and agree to perform
certain ongoing services with respect to the Units. The ongoing trailing
commissions, once begun, will continue for as long as the Unit remains
outstanding. Selling agents will pay a portion of these commissions to their
eligible representatives after deduction of "due diligence" and administrative
expenses incurred in connection with this offering, in accordance with such
selling agents' standard compensation arrangements. No selling agent will
receive upfront selling commissions or trailing commissions which exceed the
amounts set forth above.

     The general partner has agreed to indemnify the selling agents against
certain liabilities that the selling agents may incur in connection with the
offering and sale of the Units, including liabilities under the Securities Act
of 1933 and the Commodity Exchange Act.

     The selling agents will determine the suitability of prospective limited
partners in the Fund, pursuant to Rule 2810 of the National Association of
Securities Dealers, based upon information contained in the Subscription
Agreement and documents furnished to the selling agents by their customers in
opening accounts.

                      S&P MANAGED FUTURES INDEX FUND, L.P.

                          NOTES TO FINANCIAL STATEMENT

(1) ORGANIZATION

     S&P Managed Futures Index Fund, L.P. ("Fund") was organized as a limited
partnership on May 13, 2003 under the Delaware Revised Uniform Limited
Partnership Act, as amended. In accordance with the Limited Partnership
Agreement, the Fund is organized as a single series of limited partnership
units. The General Partner will pursue the Fund's investment objective by
allocating substantially all the Fund's assets to the SPhinX Managed Futures
Fund SPC (the "SPC"). The SPC is designed to track the S&P Managed Futures Index
("Index"), and thus provide limited partners with exposure to a broad cross
section of systematic managed futures strategies through a single investment.
The Fund has had no operations other than those related to organizational
matters, including the sale of 1.000 unit to RefcoFund Holdings, LLC ("RFH",
also referred to as the "General Partner") and 0.001 unit to the initial limited
partner on July 7, 2003.

     As General Partner, RFH has the sole authority and responsibility for
managing the operations of the Fund and directing the investment of Fund assets.
RFH has retained the services of PlusFunds Group, Inc. ("PlusFunds") as
Sub-Investment Manager to oversee the day-to-day investment management functions
for the Fund.

(2) SIGNIFICANT ACCOUNTING POLICIES

     A summary of the significant accounting policies, which have been followed
in preparing the accompanying financial statement, is set forth below.

     USE OF ESTIMATES

     The accompanying financial statement has been prepared in accordance with
accounting principles generally accepted in the United States of America (GAAP).
The preparation of financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and the disclosure of contingent assets and liabilities
as of the date of the financial statements, and the reported amounts of revenues
and expenses during the reporting period. Actual amounts could differ from such
estimates.

     INCOME TAXES

     Federal income taxes are not intended to be provided for as each partner is
individually liable for the taxes, if any, on its shares of Fund's taxable
income items including capital gains, interest, dividends, and deductions. In
accordance with the Limited Partnership Agreement, the limited partners may also
be subject to various state and other taxes.

                                       56
<Page>

(3) MANAGEMENT FEES

     RFH, as the general partner, will receive a management fee of 3.75%
annually of the net asset value of the Fund, calculated daily and paid monthly
in arrears, in exchange for providing ongoing advisory and general management
services.

     All fees paid to PlusFunds for sub-investment management services are paid
by RFH. RFH may voluntarily waive a portion of its management fee at its
discretion.

(4) EXPENSES

     In accordance with the Limited Partnership Agreement, the Fund shall be
charged for certain expenses, as described below, and such expenses will be
allocated proportionately among the partners.

     The Fund is responsible for administrative, ongoing offering expenses and
operating expenses, including but not limited to legal and accounting fees, and
any taxes or extraordinary expenses payable. A monthly administrative fee will
be charged to the Fund by RFH at an annual rate of 0.25% of the Fund's net
assets.

     RFH will pay organizational and initial offering expenses. RFH will also
pay initial commissions to selling agents, however RFH will receive from the
Fund an amount equal to 0.75% annually of the net asset value of the Fund until
such initial commissions plus interest have been reimbursed.

     As of July 9, 2003, the Fund has not incurred any operating expenses since
the sale of units to RFH occurred on the balance sheet date and the Fund has not
commenced operations.

PRO FORMA AGGREGATE HISTORICAL RETURNS OF INDEX

     For purposes of analysis, Standard & Poor's aggregated the historical
self-reported returns of the Index constituents for purposes of the historical
pro forma version of the Index. The S&P Managed Futures Pro Forma Index is based
on the Index constituents as of December 2002 using monthly performance data
from January 1998 through December 2002 from the constituent portfolio managers
themselves. Returns for some constituents may not extend back to January 1998.
Standard & Poor's cannot verify the validity or accuracy of this data. For
purposes of calculating pro forma returns, annually in August, the pro forma
version of the Index is rebalanced to original equal weighting of constituents.
Standard & Poor's does not guarantee the accuracy of these pro forma returns and
does not recommend any investment or other decision based on their results. Pro
forma index returns do not take into account fund distributions, up-front sales
commissions, or certain fees and commissions. If the foregoing had been factored
in, the pro forma index returns would have been lower.

Capsule D presents the results of the pro forma version of the Index.

PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS.

HYPOTHETICAL PERFORMANCE RESULTS HAVE MANY INHERENT LIMITATIONS, SOME OF WHICH
ARE DESCRIBED BELOW. NO REPRESENTATION IS BEING MADE THAT THE FUND WILL OR IS
LIKELY TO ACHIEVE PROFITS OR LOSSES SIMILAR TO THOSE SHOWN. IN FACT, THERE ARE
FREQUENTLY SHARP DIFFERENCES BETWEEN HYPOTHETICAL PERFORMANCE RESULTS AND THE
ACTUAL RESULTS ACHIEVED BY ANY PARTICULAR TRADING PROGRAM.

                                       63
<Page>

ONE OF THE LIMITATIONS OF HYPOTHETICAL PERFORMANCE RESULTS IS THAT THEY ARE
GENERALLY PREPARED WITH THE BENEFIT OF HINDSIGHT. IN ADDITION, HYPOTHETICAL
TRADING DOES NOT INVOLVE FINANCIAL RISK, AND NO HYPOTHETICAL TRADING RECORD CAN
COMPLETELY ACCOUNT FOR THE IMPACT OF FINANCIAL RISK IN ACTUAL TRADING. FOR
EXAMPLE, THE ABILITY TO WITHSTAND LOSSES OR TO ADHERE TO A PARTICULAR TRADING
PROGRAM IN SPITE OF TRADING LOSSES ARE MATERIAL POINTS WHICH CAN ALSO ADVERSELY
AFFECT ACTUAL TRADING RESULTS. THERE ARE NUMEROUS OTHER FACTORS RELATED TO THE
MARKETS IN GENERAL OR TO THE IMPLEMENTATION OF ANY SPECIFIC TRADING PROGRAM
WHICH CANNOT BE FULLY ACCOUNTED FOR IN THE PREPARATION OF HYPOTHETICAL
PERFORMANCE RESULTS AND ALL OF WHICH CAN ADVERSELY AFFECT ACTUAL TRADING
RESULTS.

THE FUTURES AND FORWARD MARKETS

FUTURES AND FORWARD CONTRACTS

     Futures contracts in the United States are generally traded on exchanges
and call for the future delivery of various commodities. These contractual
obligations may be satisfied either by taking or making physical delivery or by
making an offsetting sale or purchase of a futures contract on the same
exchange.

     Forward currency contracts are agreements to make or accept delivery of a
currency and are traded off-exchange through banks or dealers. In these
instances, the bank or dealer generally acts as principal in the transaction and
charges "bid-ask" spreads. These contractual obligations are generally satisfied
by making an offsetting agreement.

     Unlike an investment in bonds where some consistency of yield is expected
or in stocks where participation in economic growth is expected, futures and
forward trading is a "zero-sum" risk transfer economic activity. For every gain
realized by one futures and forward trader, there is an equal and offsetting
loss suffered by another.

HEDGERS AND SPECULATORS

     The two broad classifications of persons who trade futures and forward
contracts are "hedgers" and "speculators." Hedging is designed to minimize the
losses that may occur because of price changes, for example, between the time a
merchandiser contracts to sell a commodity and the time of delivery. The futures
and forward markets enable the hedger to shift the risk of price changes to the
speculator. The speculator risks capital with the hope of making profits from
such changes. Speculators, such as the Fund, rarely take delivery of the
physical commodity but rather close out their futures positions through
offsetting futures contracts.

EXCHANGES; POSITION AND DAILY LIMITS; MARGINS

     Commodity exchanges in the United States generally have an associated
clearinghouse. Once trades made between members of an exchange have been
cleared, each clearing broker

                                       64
<Page>

looks only to the clearinghouse for all payments in respect of such broker's
open positions. The clearinghouse "guarantee" of performance on open
positions does not run to customers. If a member firm goes bankrupt,
customers could lose money.

     Federal legislation adopted in December 2000 has made possible a variety of
new futures and derivative exchanges and clearing organizations that will be
subject to less CFTC oversight than are the commodities exchanges on which the
Index SPC anticipates trading in the United States. Additionally, this
legislation permits a variety of highly qualified persons to trade contracts for
future delivery on various non-agricultural commodities among themselves
off-exchange. The general partner currently expects that substantially all of
the Index SPC's futures trading in the United States will be conducted on
exchanges subject to the full oversight of the CFTC. However, it is not now
possible to determine what impact the existence of these new exchanges will have
on the Index SPC's trading activities.

     The Index SPC will trade on a number of foreign commodity exchanges.
Foreign commodity exchanges differ in certain respects from their United States
counterparts and are not regulated by any United States agency.

     The CFTC and the United States exchanges have established "speculative
position limits" on the maximum positions that the portfolio managers may hold
or control in futures contracts on some, but not all, commodities. For example,
the CFTC limits the number of contracts each portfolio manager can control in
corn to 5,500 in a single delivery month and the Chicago Mercantile Exchange
limits the number of S&P 500 Index contracts each portfolio manager can control
to 20,000; however, Treasury bonds traded on the Chicago Board of Trade are not
subject to position limits.

     United States exchanges limit the maximum price change in some, but not
all, futures contracts during any single trading day. Once the "daily limit" has
been reached, it becomes very difficult to execute trades in the same direction
the market has moved. That is, if a market is "limit up," it is difficult, or
impossible, to buy, but very easy to sell. Because these limits apply on a
day-to-day basis, they do not limit ultimate losses, but may reduce or
temporarily eliminate liquidity. For example, the Chicago Board of Trade imposes
daily limits of 20(cent) on corn futures but imposes no daily limits on Treasury
bond futures. The Chicago Mercantile Exchange coordinates trading halts in the
S&P 500 index futures with trading halts of the stocks underlying the index and
imposes trading pauses or halts at moves of 5%, 10%, 15% and 20% in the value of
that index.

     When a position is established, "initial margin" is deposited. On most
exchanges, at the close of each trading day "variation margin," representing the
unrealized gain or loss on the open positions, is either credited to or debited
from a trader's account. If "variation margin" payments cause a trader's
"initial margin" to fall below "maintenance margin" levels, a "margin call" is
made, requiring the trader to deposit additional margin or have his position
closed out.

GLOSSARY

     The following glossary may assist the prospective investor in understanding
the terms used in this prospectus.

                                       65

capacity.

CFTC. Commodity Futures Trading Commission.

COMMODITY. The term commodity refers to goods, wares, merchandise, produce and
in general everything that is bought and sold in commerce, including financial
instruments. Out of this large class, certain commodities have been selected as
appropriate vehicles for trading on various national and international exchanges
located in principal marketing and commercial areas. Among the commodities
currently so traded are wheat, corn, oats, hogs, sugar, cotton, lumber, copper,
silver, gold, T-Bills, stock indices and foreign currency.

or any person who will manage or participate in the management of the Fund,
including a commodity broker who pays any portion of the organizational expenses
of the Fund, the general partner and any other person who regularly performs or
selects the persons who perform services for the Fund. Sponsor does not include

                4.      TERM; DISSOLUTION; AND FISCAL YEAR.

                (a)     TERM. The term of the Partnership shall commence on the
day on which the Certificate of Limited Partnership was filed with the Secretary
of State of the State of Delaware pursuant to the provisions of the Act and
shall end upon the first to occur of the following: (i) receipt by the General
Partner of an election to dissolve the Partnership at a specified time by the
Limited Partners owning Units representing more than fifty percent (50%) of the
total number of outstanding Units then owned by Limited Partners, notice of
which is sent by registered mail to the General Partner not less than 90 days
prior to the effective date of such dissolution; (ii) the withdrawal,
resignation, removal, bankruptcy, insolvency or dissolution of the General
Partner or any other event that causes the General Partner to cease to be a
general partner unless (A) at the time of such event there is at least one
remaining general partner of the Partnership who carries on the business of the
Partnership or (B) within 120 days after such event Limited Partners owning at
least fifty percent (50%) of the total number of outstanding Units then owned by
Limited Partners agree to continue the business of the Partnership and to the
appointment, effective as of the date of such event, of one or more general
partners of the Partnership pursuant to the terms of SECTION 17; and (iii) any
other event which shall make it unlawful for the existence of the Partnership to
be continued or shall require termination of the Partnership.

                (b)     DISSOLUTION. Upon the dissolution of the Partnership,
the assets of the Partnership shall be distributed: (i) first, to creditors,
including any Partners who may be creditors, to the extent otherwise permitted
by law, in satisfaction of liabilities of the Partnership (whether by payment or
the making of reasonable provision for payment thereof) other than liabilities
for which reasonable provision for payment has been made and liabilities for
distributions to Partners; (ii) second, to Partners and former Partners in
satisfaction of liabilities for distributions; and (iii) third, to Partners
first for the return of their contributions and second respecting their
partnership interests, in the proportions in which the Partners share in
distributions. Following distribution of the assets of the Partnership, a
Certificate of Cancellation for the Partnership shall be filed as required by
the Act.

                (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.

                (a)     MINIMUM NET WORTH. At all times after termination of the
Initial Offering Period, so long as it remains general partner of the
Partnership, the General Partner will maintain a Net Worth of not less than the
greater of (a) $50,000 or (b) the sum of five percent (5%) of the total capital
contributions to the Partnership (including capital contributions by the General
Partner) and to all other entities of which it is general partner and five
percent (5%) of the Units being offered. In no event shall the General Partner
be required to maintain a Net Worth in excess of $1,000,000.

                (b)     MODIFICATIONS. The requirements of SECTION 5(a) may be
modified by the General Partner if the General Partner obtains an opinion of
counsel for the Partnership that a proposed modification will not adversely
affect the classification of the Partnership as a

                                       A-2

partnership for federal income tax purposes and will not violate any state
securities or blue sky laws to which the Partnership may be subject from time to
time.

                6.      CAPITAL CONTRIBUTIONS; UNITS; AND DISTRIBUTIONS.

                (a)     GENERAL PARTNER INTEREST. The General Partner will be
required to make and maintain a cash investment in the Partnership equal to the
greater of (i) one percent (1%) of the total capital contributions to the
Partnership or (ii) $25,000. The General Partner may withdraw any interest it
may have as a general partner in excess of such amount. Any interest in the
Partnership acquired by the General Partner or any of its principals or their
respective Affiliates will be non-voting, and will not be considered outstanding
for purposes of determining whether the majority approval of the outstanding
Units has been obtained.

                (b)     INITIAL LIMITED PARTNER. The capital contribution of the
initial Limited Partner shall be $1, payable on formation of the Partnership.
The interest of the Initial Limited Partner shall terminate on admission of any
other person as a Limited Partner and his capital contribution shall be
returned.

                (c)     LIMITED PARTNER INTERESTS. Interests in the Partnership,
other than those of the General Partner, shall be evidenced by units of limited
partnership interest ("Units"). In accordance with the Prospectus, the General
Partner, on behalf of the Partnership, shall sell, or cause to be sold, Units to
Persons desiring to become Limited Partners.

                (i)     During the Initial Offering Period, a subscriber must
        contribute $1,000 per Unit and purchase at least ten Units, making its
        initial investment to the capital of the Partnership at least $10,000;
        provided, that a subscriber that is an individual retirement account
        must purchase at least three Units, making its initial investment to the
        capital of the Partnership at least $3,000. During the Initial Offering
        Period, a subscriber who has previously submitted a Subscription
        Agreement to purchase Units may make additional investments of at least
        $2,500 to purchase Units at $1,000 per Unit. The Limited Partners'
        respective capital contributions to the Partnership shall be as shown on
        the books and records of the Partnership. Units will be sold in
        fractions calculated to three decimal places.

                (ii)    During the Initial Offering Period, all subscriptions
        received will be held in an interest bearing escrow account with an
        escrow agent selected by the General Partner. The General Partner must
        receive and accept subscriptions for at least 30,000 Units prior to the
        termination of the Initial Offering Period to break escrow and commence
        trading. If subscriptions for at least 30,000 Units have not been
        received and accepted by the General Partner prior to the termination of
        the Initial Offering Period, this Agreement shall terminate, the full
        amount of all subscriptions held in escrow, plus interest, will be
        returned to the subscribers within five Business Days after the end of
        the Initial Offering Period and the Certificate of Limited Partnership
        shall be cancelled. If subscriptions for at least 30,000 Units have been
        received and accepted by the General Partner prior to the termination of
        the Initial Offering Period, the full amount of all subscriptions held
        in escrow will be contributed to the Partnership, the interest earned on

                                       A-3
<Page>

        such subscriptions shall be treated as interest earned by the
        Partnership and the Partnership shall commence trading operations.

                (iii)   After the termination of the Initial Offering Period,
        Units will be continuously offered for sale as of the first Business Day
        of each month at their Net Asset Value. A subscriber must make an
        initial investment to the capital of the Partnership of at least
        $10,000; provided, that a subscriber that is an individual retirement
        account must make its initial investment to the capital of the
        Partnership of at least $3,000. An existing Limited Partner may make
        additional investments of at least $2,500. Subscription Agreements must
        be received at least five Business Days prior to the first Business Day
        of each month in order to be accepted and the related cleared funds must
        be received at least three Business Days prior to the first Business Day
        of each month in order for subscriptions to be accepted. Funds will be
        held in the Partnership's escrow or bank account until the first
        Business Day of the month beginning at least five Business Days after
        receipt of the related Subscription Agreement. Interest earned on funds
        submitted prior to the first Business Day of the month will be interest
        earned by the Partnership. If a subscription is rejected, the related
        funds held in the Partnership's escrow or bank account, plus interest,
        will be returned to the subscriber promptly following the end of the
        month in which the subscription was rejected.

                (d)     DISTRIBUTIONS. The General Partner shall have sole
discretion in determining what distributions (other than on redemption of
Units), if any, the Partnership will make to the Partners. Distributions shall
be PRO RATA in accordance with the respective capital accounts of the Partners.

                (e)     NO CERTIFICATES. No certificates or other evidences of
Unit ownership will be issued. All subscribers who have been accepted by the
General Partner shall be deemed admitted as Limited Partners at the time they
are reflected as such on the books and records of the Partnership.

                (f)     RETURN OF CAPITAL CONTRIBUTIONS. No Limited Partner or
assignee shall have any right to demand the return of his or her capital
contribution or any profits added thereto, except through redeeming Units or
upon dissolution of the Partnership, in each case as provided herein. In no
event shall a Limited Partner or assignee be entitled to demand or receive
property other than cash.

                7.      ALLOCATION OF PROFITS AND LOSSES.

                (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 the initial capital contribution to the Partnership made by such
Partner.

                (b)     ALLOCATIONS. As of the close of business on the last day
of each month, the following determinations and allocations shall be made:

                (i)     The Net Assets of the Partnership will be determined
        without regard to Management Fees or Administration Fees.

                                       A-4
<Page>

                (ii)    Management Fees, if any, shall then be charged against
        Net Assets.

                (iii)   Administration Fees, if any, shall then be charged
        against Net Assets.

                (iv)    Any increase or decrease in the Partnership's Net Assets
        (after the adjustments determined pursuant to Paragraphs (i) through
        (iii) above), as compared to the last such determination of Net Assets,
        shall then be credited or charged to the capital accounts of each
        Partner in the ratio that the balance of each capital account bears to
        the balance of all capital accounts.

                (v)     The amount of any distributions to a Partner and any
        amount paid to a Partner on redemption of Units shall be charged to the
        appropriate capital account. The General Partner does not intend to make
        any distributions.

                (c)     ALLOCATION OF PROFIT AND LOSS FOR FEDERAL INCOME TAX
PURPOSES. As of the end of each fiscal year, income and expense and capital gain
or capital loss of the Partnership shall be allocated among the Partners
pursuant to the following provisions for federal income tax purposes:

                (i)     For federal income tax purposes, items of ordinary or
        capital income, gain, loss, deduction or credit for each fiscal year
        shall be allocated among the Partners in such manner as to reflect as
        nearly as possible the amounts credited or charged to each Partner's
        capital account.

                (ii)    Unrealized ordinary or capital gains or losses from
        prior periods that have been credited or charged to a Partner's capital
        account shall, when realized, be allocated as nearly as possible for
        federal income tax purposes to reflect such prior allocation to a
        Partner's capital account.

                (iii)   Allocations hereunder shall be made in accordance with
        the regulations promulgated by the Department of the Treasury under
        Section 704(b) and Section 704(c) of the Internal Revenue Code of 1986,
        as amended (the "Code"), and, in the case of allocations made in
        accordance with SECTION 7(d)(ii), may be made in accordance with the
        provisions in Temporary Treasury Regulation 1.704-3(e)(3) (or successor
        regulations) for "securities partnerships" to the extent the Partnership
        constitutes a "securities partnership" within the meaning of such
        provisions.

                (iv)    Notwithstanding SECTION 7(c)(ii), to the extent
        permitted by the regulations (or successor regulations) referred to in
        SECTION 7(c)(iii), allocations of gains that have been realized up to
        the time a Partner has redeemed all or any portion of his limited or
        general partnership interest may be allocated first to each Partner who
        has redeemed any such interest during the year to the extent that the
        amount the Partner received on redemption exceeds the amount of the
        Partner's tax basis attributable to the interest redeemed, and
        allocations of losses that have been realized up to the time a Partner
        has redeemed all or any portion of his limited or general partnership
        interest may be allocated first to each Partner who has redeemed any
        such interest during the year to the extent that the amount of the
        Partner's tax basis attributable to the interest redeemed exceeds the
        amount the Partner received on redemption. If more than one Partner
        receives a special

                                       A-5
<Page>

        allocation described above, the allocation to each Partner may be made
        in proportion to the ratio that such Partner's tax basis bears to the
        total tax basis for all interests redeemed at that time.

                (v)     Any Partner who transfers or assigns Units during any
        fiscal year shall be allocated such Partner's proportionate share of the
        capital gain or capital loss and ordinary income or loss realized by the
        Partnership through the end of the month in which notice of such
        transfer or assignment is given to the General Partner in accordance
        with SECTION 11, and the transferee or assignee of such Units shall be
        allocated its proportionate share of the capital gain or capital loss
        and ordinary income or loss realized by the Partnership commencing with
        the month next succeeding the month in which notice of the transfer or
        assignment is given.

                (vi)    For purposes of this SECTION 7(c), "capital gain" or
        "capital loss" shall mean gain or loss characterized as gain or loss
        from the sale or exchange of a capital asset by the Code, including gain
        or loss required to be taken into account pursuant to Section 1256
        thereof.

                (vii)   Capital gain and capital loss shall be allocated
        separately and not netted.

                (viii)  The allocation of profit and loss for federal income tax
        purposes set forth herein allocates taxable profit and loss among the
        Partners in the ratio and to the extent that financial profit and loss
        are allocated to such Partners and so as to eliminate, to the maximum
        practicable extent, any disparity between a Partner's capital account
        and its tax account, consistent with principles set forth in Section 704
        of the Code, including a "Qualified Income Offset."

                (ix)    The allocations of profit and loss to the Partners in
        respect of their Units shall not exceed the allocations permitted under
        Subchapter K of the Code, as determined by the General Partner, whose
        determination shall be binding.

                (x)     The method for allocating gains and loses for federal
        tax purposes may be changed by the General Partner upon receipt of
        advice from counsel to the Partnership that such change is required by
        applicable law or regulations.

                8.      FEES AND EXPENSES.

                (a)     MANAGEMENT FEES. The Partnership shall pay to the
General Partner a monthly management fee (the "Management Fee") equal to 0.3125%
of the Partnership's month-end Net Assets (3.75% per annum). Management Fees,
accrued as well as paid, shall reduce Net Asset Value. The Management Fees,
Administrative Fees and customary and routine administrative expenses of the
Partnership, other than the actual cost of legal and audit services and
extraordinary expenses ("Customary Administrative Expenses"), may not exceed
0.5% of the Partnership's month-end Net Assets (6% per annum). If necessary, the
General Partner shall reimburse the Partnership, no less frequently than
quarterly, for the amount by which the Management Fees, Administrative Fees and
Customary Administrative Expenses exceed such limitation.

<Page>

                (i)     The General Partner shall pay all expenses incurred in
        connection with the organization of the Partnership and the initial
        offering of Units. The organization and initial offering expenses shall
        be paid by the General Partner out of the Management Fee. The
        organizational and offering expenses, plus the Upfront Selling
        Commissions and other commissions and compensation for sales of Units,
        may not exceed 15% of the total capital contributions of the Partners.

                (ii)    Beginning in the 13th month following the purchase of
        any Units, the General Partner shall pay to the selling agent of such
        Units a monthly trailing commission equal to 0.1875% (2.25% per annum)
        of the Partnership's month-end Net Assets per Unit multiplied by the
        number of Units placed by such selling agent. The monthly trailing
        commissions shall be paid by the General Partner from the Management
        Fee.

                (b)     ADMINISTRATIVE EXPENSES.

        of the Partnership's month-end Net Assets (0.25% per annum).
        Administrative Fees, accrued as well as paid, shall reduce Net Asset
        Value. The Administrative Fees, Management Fees and Customary
        Administrative Fees may not exceed 0.5% of the Partnership's month-end
        Net Assets (6% per annum). If necessary, the General Partner shall
        reimburse the Partnership, no less frequently than quarterly, for the
        amount by which the Administrative Fees, Management Fees and Customary
        Administrative Expenses exceed such limitation.

                (ii)    The Partnership shall be billed for and shall pay all of
        its administrative expenses, including all Customary Administrative
        Expenses, legal and audit services expenses and extraordinary expenses.
        The General Partner shall pay and shall not allocate to the Partnership
        any of its indirect expenses incurred in connection with the
        administration of the Partnership, including salaries, rent, travel
        expenses and such other items generally falling under the category of
        overhead expenses, except for organizational and offering expenses.

                (iii)   The Partnership shall pay its pro rata share of the fees
        and expenses of the Index SPC. The fees and expenses of the Index SPC
        include (A) management fees and incentive fees paid to the managers of
        the Index SPC; (B) fees paid to the Index SPC's administrator to
        administer the Index SPC; (C) brokerage commissions and other
        transaction-related expenses of the Index SPC; (D) accounting, audit and
        legal expenses and custodial fees of the Index SPC; and (E) any
        extraordinary expenses of the Index SPC.

                (c)     UPFRONT SELLING COMMISSION. The General Partner shall
pay to each selling agent of any Units an upfront selling commission equal to
3.00% of the subscription amount for such Units (the "Upfront Selling
Commissions"). The Partnership shall reimburse the General Partner for all
Upfront Selling Commissions monthly at a rate of 0.0625% of the Partnership's
month-end Net Assets (0.75% per annum) plus interest on such amount; provided,
that the Partnership shall have no obligation to reimburse the General Partner
for any amount in

                                       A-7
<Page>

excess of the aggregate amount of Upfront Selling Commissions paid by the
General Partner to the selling agents plus interest on such amount. Upfront
Selling Commissions, plus the organizational and offering expenses and other
commissions and compensation for sales of Units, may not exceed 15% of the total
capital contributions of the Partners.

                (d)     ORGANIZATIONAL EXPENSES. The Partnership shall pay all
expenses incurred in connection with the ongoing offering of Units. The
organizational and offering expenses, plus the Upfront Selling Commissions and
other commissions and compensation for sales of Units, may not exceed 15% of the
total capital contributions of the Partners.

                (e)     RESERVES. The General Partner may create, in its sole
and absolute discretion, appropriate reserves, which shall be accrued and
charged against the 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 Net Asset Value for all purposes.

                9.      MANAGEMENT OF THE PARTNERSHIP.

                (a)     AUTHORITY OF THE GENERAL PARTNER. The General Partner
shall control, conduct and manage the business of the Partnership, including the
investment of the funds of the Partnership. The General Partner may take such
actions on behalf of the Partnership as the General Partner deems, in its sole
discretion, necessary or desirable to manage the business of the Partnership.
The General Partner shall have sole discretion in determining what distributions
of profits and income, if any, shall be made to the Partners (subject to the
allocation provisions hereof), shall execute various documents on behalf of the
Partnership and the Limited Partners and shall supervise the liquidation of the
Partnership if an event causing dissolution of the Partnership occurs.

                (b)     AGREEMENTS AND ARRANGEMENTS. The Partnership and the
General Partner on behalf of the Partnership may enter into any agreements or
arrangements specifically described in or contemplated by the Prospectus or
otherwise as the General Partner deems, in its sole discretion, necessary or
desirable to manage the business of the Partnership without any further act,
approval or vote of any Limited Partner other than the General Partner.

                (c)     PROHIBITED ACTIVITIES.

                (i)     The funds of the Partnership will not be commingled with
        the funds of any other Person (deposit of funds with a commodity broker,
        clearinghouse or forward dealer, entering into joint ventures or
        partnerships, or investing assets in the Index SPC or any other
        collective investment vehicle shall not be deemed to constitute
        "commingling" for these purposes).

                (ii)    The Partnership shall make no loans to any Person. The
        General Partner shall make no loans to the Partnership.

                (iii)   The Partnership shall not employ the trading technique
        commonly known as "pyramiding," which means using unrealized profit on
        existing positions as margin for the purchase or sale of additional
        positions in the same or related commodities. The General Partner taking
        into account the Partnership's open trade equity on existing

                                       A-8
<Page>

        positions in determining generally whether to acquire additional
        commodity positions on behalf of the Partnership will not be considered
        to be engaging in "pyramiding."

                (iv)    No Person may receive, directly or indirectly, any
        advisory, management or incentive fees, or any profit-sharing allocation
        from joint ventures, partnerships or similar arrangements in which the
        Partnership participates, for investment advice or management who shares
        or participates in any commodity brokerage commissions paid by the
        Partnership; no broker may pay, directly or indirectly, rebates or
        give-ups to any trading advisor or manager or to the General Partner or
        any of their respective Affiliates; and such prohibitions may not be
        circumvented by any reciprocal business arrangements.

                (v)     Neither the General Partner nor any Affiliate of the
        General Partner shall directly or indirectly pay or award any
        commissions or other compensation to any Person engaged to sell Units or
        to give investment advice to a potential Limited Partner; provided, that
        neither the General Partner nor any Affiliate of the General Partner is
        prohibited from paying to a registered broker-dealer or other properly
        licensed Person normal sales commissions for selling Units.

                (vi)    The maximum period covered by any contract entered into
        by the Partnership shall not exceed one year (although such contracts
        may be automatically renewable for successive one year periods until
        terminated). Any agreements between the Partnership and the General
        Partner or any of its Affiliates shall be terminable by the Partnership
        upon no more than 60 days' written notice.

                (vii)   No material change in the basic investment policies or
        structure of the Partnership shall be made without the approval of
        Limited Partners owning Units representing more than fifty percent (50%)
        of the total outstanding Units owned by Limited Partners as of a record
        date established for a vote thereon.

                (viii)  The General Partner may not assign its general liability
        interest or its obligation to direct the trading of the Partnership
        without the consent of each Limited Partner.

                (d)     FREEDOM OF ACTION. The General Partner is engaged in,
and may in the future engage in, other business activities and shall not be
required to refrain from any other activity nor forego any profits from any such
activity, whether or not in competition with the Partnership. Neither the
Partnership nor any other Partner shall have any right by virtue of this
Agreement in or to The General Partner shall devote to the Partnership such time
as the General Partner may deem advisable to the conduct of the Partnership's
business and affairs.

                (e)     TAX MATTERS PARTNER. The General Partner is hereby
authorized to perform all duties imposed by Sections 6221 through 6232 of the
Code on the General Partner as the "tax matters partner" of the Partnership. The
General Partner may, in its sole discretion, make a mixed straddle account
election on behalf of the Partnership and elections under Sections 988, 1092 and
1256 of the Code on behalf of the Partnership.

                                       A-9

                10.     AUDITS AND REPORTS TO LIMITED PARTNERS.

                (a)     FINANCIAL AND TAX INFORMATION. The Partnership's books
shall be audited annually by an independent certified public accountant selected
by the General Partner. The Partnership will use its best efforts to cause each
Limited Partner to receive (i) within 90 days after the end of each fiscal year,
an "Annual Report" as required by CFTC Regulation 4.22(c) and such tax
information as is necessary for a Limited Partner to complete his or her federal
income tax return and (ii) ) within 30 days of the end of each month, a "Monthly
Account Statement" as required by CFTC Regulation 4.22(a). The General Partner
will comply with the reporting requirements of CFTC Regulation 4.22 with respect
to the Partnership.

                (b)     INSPECTION OF BOOKS AND RECORDS. Limited Partners or
their duly authorized representatives may inspect the books and records of the
Partnership during normal business hours upon reasonable written notice to the
General Partner and may obtain copies of such records upon payment of reasonable
reproduction costs; provided, that upon request by the General Partner, the
requesting Limited Partner shall represent that the inspection and/or copies of
such records will not be used for commercial purposes unrelated to such Limited
Partner's interest as an investor in the Partnership.

                (c)     CALCULATION OF NET ASSET VALUE. The General Partner
shall calculate the Net Assets of the Partnership daily and shall make the
approximate Net Asset Value available upon the request of a Limited Partner for
a purpose reasonably related to such Limited Partner's interest as a limited
partner in the Partnership.

                (d)     NOTIFICATION. The General Partner will send written
notice to each Limited Partner within seven Business Days of the occurrence of:

                (i)     any decline in the Net Asset Value per Unit to less than
        fifty percent (50%) of such Net Asset Value as of the previous month-end
        valuation date; and

                (ii)    any other material change affecting the compensation of
        any party.

Each such notification shall set forth the Limited Partners' voting and
redemption rights and a description of any material effect such change may have
on the Units.

                (e)     TAXES. 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 required to be filed by the Partnership. The
General Partner shall cause the Partnership to pay any taxes payable by the
Partnership; provided, that such taxes need not be paid if the General Partner
or the Partnership are in good faith and by appropriate legal proceedings
contesting the validity, applicability or amount thereof, and such contest does
not materially endanger any right or interest of the Partnership.

                (f)     MAINTENANCE OF RECORDS. The General Partner shall
maintain and preserve all required records relating to the Partnership for a
period of not less than six years from the receipt of such records.

                                      A-10
<Page>

                11.     ASSIGNABILITY OF UNITS.

                (a)     NOTICE OF TRANSFER. Each Limited Partner expressly
agrees that he or she will not assign, transfer or dispose of, by gift or
otherwise, any of his or her Units or any part or all of his or her right, title
and interest in the capital or profits of the Partnership without giving fifteen
days' prior written notice to the Partnership and the General Partner. Such
written notice shall specify the name and residence address of the assignee, the
date of assignment, shall include a statement by the assignee that he or she
agrees to give the above-described written notice to the General Partner upon
any subsequent assignment and shall be signed by the assignor and assignee. If
an assignment, transfer or disposition occurs by reason of the death of a
Limited Partner, such written notice may be given by the duly authorized
representative of the estate of the Limited Partner and shall be supported by
such proof of legal authority and valid assignment as may be reasonably
requested by the General Partner. No assignment, transfer or disposition by a
Limited Partner of Units or of any part of his or her right, title and interest
in the capital or profits of the Partnership shall be effective against the
Partnership or the General Partner until the first day of the month following
the month in which the Partnership and the General Partner receive such written
notice of the assignment, and the General Partner shall not be required to give
any assignee any rights hereunder prior to such time. The General Partner may,
in its sole discretion, waive any such notice or any defect therein. The General
Partner will send written confirmation to both the transferor and transferee of
Units that the transfer in question has been duly recorded on the Partnership's
books and records.

                (b)     SUBSTITUTE LIMITED PARTNERS. No assignee may become a
substituted Limited Partner, except with the consent of the General Partner and
upon execution and delivery of an instrument of transfer in form and substance
satisfactory to the General Partner; provided, that the General Partner may
withhold such consent only if it is necessary (i) to prevent the Partnership
from being treated as a publicly traded partnership or (ii) to preserve the tax
status of the Partnership or the characterization or treatment of income or loss
and such restriction is supported by an opinion of counsel. If the General
Partner withholds consent, an assignee shall not become a substituted Limited
Partner, and shall not have any of the rights of a Limited Partner, except that
the assignee shall be entitled to receive that share of capital and profits and
shall have that right of redemption to which his or her assignor would otherwise
have been entitled. A substituted Limited Partner shall have all of the rights
and powers and shall be subject to all of the restrictions and liabilities of
Limited Partner of the Partnership. A substituted Limited Partner shall be
liable for the obligations of his or her assignor to make contributions to the
Partnership, but shall not be liable for the obligations of his assignor under
the Act to return distributions received by the assignor; provided, that a
substituted Limited Partner shall not be obligated for liabilities unknown to
him or her at the time he or she became a substituted Limited Partner and which
could not be ascertained from this Agreement. An assigning Limited Partner shall
remain liable to the Partnership as provided in the Act, regardless of whether
his or her assignee becomes a substituted Limited Partner. Each Limited Partner
agrees that any assignee may become a substituted Limited Partner without need
of the further act or approval of any Limited Partner.

                (c)     RESTRICTIONS ON TRANSFER. No assignment, transfer or
disposition of any Units shall be made in violation of any applicable federal or
state securities laws. The General Partner will not permit the assignment,
transfer or disposition of Units where, after the

                                      A-11
<Page>

assignment, transfer or disposition, either the Limited Partner or the assignee
would hold less than the minimum number of Units equivalent to an initial
minimum purchase (as stated in the then-current Prospectus), except for
assignments, transfers or dispositions by gift, inheritance, intrafamily
transfers, family dissolutions or transfers to Affiliates of the Limited
Partner. The General Partner will not permit the assignment, transfer or
disposition of Units where the General Partner has received an opinion of
counsel that such assignment, transfer or disposition would cause the
Partnership to be treated as a publicly traded partnership.

                (d)     MODIFICATION OF RESTRICTIONS. The General Partner shall
eliminate or modify any restriction on assignment or substitution at such time
as the General Partner receives an opinion of counsel that such restriction is
no longer necessary.

                (e)     COSTS OF TRANSFER. The assignor of a Unit shall bear the
costs related to such assignment or transfer. Certificates representing Units
may bear appropriate legends to such effect.

                12.     REDEMPTIONS.

                (a)     NOTICE OF REDEMPTION; REDEMPTION PRICE. Each Limited
Partner and each assignee of Units of whom the General Partner has received
written notice pursuant to SECTION 11 may redeem all or any of his or her Units
effective as of the close of business on the last Business Day of any calendar
month by delivering to the General Partner a written request for redemption in a
form specified by the General Partner at least 10 Business Days prior to the
date of redemption; provided, that all liabilities, contingent or otherwise, of
the Partnership (including the Partnership's allocable share of the liabilities,
contingent or otherwise, of any entities in which the Partnership invests),
except any liability to Limited Partners on account of their capital
contributions, have been paid or there remains property of the Partnership
sufficient to pay them. All redemptions will be made at the Net Asset Value of
the redeemed Units as of the effective date of the redemption.

                (b)     REDEMPTION CHARGES. Limited Partners who redeem Units on
or prior to the end of the first year after such Units are sold will be assessed
a redemption charge (the "Redemption Charge") equal to 3% of the Net Asset Value
of the Units redeemed as of the date of redemption. Units purchased by the same
Limited Partner on different closing dates will be treated on a "first-in,
first-out" basis for purposes of calculating whether they have been held for a
year. All Redemption Charges will be paid to the General Partner.

                (c)     SPECIAL REDEMPTION DATES. The General Partner may permit
some or all Limited Partners to redeem Units as of dates other the last Business
Day of any calendar month upon written notice to the Limited Partners and
assignees of whom the General Partner has received written notice pursuant to
SECTION 11. The General Partner shall declare such a special redemption date
whenever the Partnership experiences a decline in Net Asset Value per Unit as of
the close of business on any Business Day to less than 50% of the Net Asset
Value per Unit on the last valuation date. The Partnership shall suspend trading
during such special redemption period.

                                      A-12
<Page>

                (d)     PAYMENT. Redemption payments will be made (by mailing a
check or crediting a customer securities account) within 10 Business Days after
the redemption date. The General Partner will make arrangements with selling
agents who so request to pay redemptions through crediting Limited Partners'
customer securities accounts with such selling agents. Redemptions may be
temporarily suspended if, in the General Partner's judgment, additional
redemptions would impair the ability of the Partnership to meet its objectives
or if a market disruption results in the closing of financial markets in the
United States or abroad and it is impossible or impracticable to value the Units
or liquidate Partnership assets. In addition, the right of a Partner to receive
a redemption payment further depends on the Partnership's ability to obtain the
necessary funds by redeeming its investment in the Index SPC, which is subject
to certain limits. Under these limits, redemptions of interests in the Index SPC
by the Partnership as of any particular redemption date cannot exceed 20% of the
Partnership's investment in the Index SPC as of that date unless the Index SPC
has received at least 15 business days' notice prior to a redemption date. The
General Partner will notify the Limited Partners in writing if redemptions are
suspended.

                (e)     REQUIRED REDEMPTION. The General Partner may require a
Limited Partner to redeem all or a portion of such Limited Partner's Units if
the General Partner considers doing so to be desirable for the protection of the
Partnership, and will use its best efforts to do so to the extent necessary to
prevent the Partnership from being deemed to hold "plan assets" under the
provisions of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), or Section 4975 of the Code with respect to any "employee benefit
plan" as defined in and subject to ERISA or with respect to any "plan" as
defined in Section 4975 of the Code.

                13.     OFFERING OF UNITS.

                (a)     REGISTRATION OF UNITS. The General Partner on behalf of
the Partnership shall (i) cause to be filed from time to time a Registration
Statement, and such amendments thereto as the General Partner may deem
advisable, with the Securities and Exchange Commission for the registration and
ongoing public offering of Units, (ii) use its best efforts to qualify Units for
sale from time to time under the securities laws of such states of the United
States or other jurisdictions as the General Partner shall deem necessary or
advisable and (iii) take such action with respect to the matters described in
(i) and (ii) as the General Partner shall deem necessary or advisable.

                (b)     ERISA RESTRICTIONS. The General Partner shall not accept
any subscriptions for Units if doing so would cause the Partnership to be
considered to hold "plan assets" for any purpose of ERISA or Section 4975 of the
Code with respect to any "employee benefit plan" as defined in and subject to
ERISA or with respect to any "plan" as defined in Section 4975 of the Code.

                (c)     CANCELLATION OF UNITS. All Units subscribed for upon
transfer of funds from a subscriber's account (or receipt of a check in the
subscription amount) are issued subject to the collection of the funds
represented by such transfer (or check). In the event that a transfer (or check)
of a subscriber is not honored, the Partnership shall cancel the Units issued to
such subscriber in consideration of such dishonored transfer (or check);
provided, that the General Partner may waive such cancellation upon receipt of
what it believes to be reasonable assurances

that such transfer (or check) will be honored or replaced by another transfer
(or check) which will be honored within 10 Business Days of original dishonor.
Any losses or profits sustained by the Partnership in connection with its
trading allocable to cancelled Units shall not be a liability of the General
Partner but shall be deemed an increase or decrease in the Net Assets of the
Partnership and allocated as described in SECTION 7. Each subscriber agrees to
reimburse the Partnership for any expense or losses incurred in connection with
any such cancellation of Units issued to such subscriber.

                14.     SPECIAL POWER OF ATTORNEY.

                Each Limited Partner by virtue of having purchased or otherwise
acquired Units does hereby irrevocably constitute and appoint the General
Partner and each officer of the General Partner, with full power of
substitution, as his or her true and lawful attorney-in-fact, in his or her
name, place and stead, to (a) execute, acknowledge, swear to, deliver, record
and file: (i) this Agreement, including any amendments and/or restatements
hereto duly adopted as provided herein; (ii) all other agreements described
herein or in the Prospectus, including any amendments hereto and thereto, and
(iii) all certificates, documents and other instruments that the General Partner
deems appropriate to qualify or continue the Partnership in the State of
Delaware and the jurisdictions in which the Partnership may conduct business, or
which may be required to be filed by the Partnership or the Limited Partners
under the laws of any jurisdiction to reflect the dissolution or termination of
the Partnership; and (b) to file, prosecute, defend, settle or compromise
litigation, claims or arbitrations on behalf of the Partnership. The Power of
Attorney granted herein shall be irrevocable and deemed to be a power coupled
with an interest (including the interest of the other Limited Partners in the
General Partner being able to rely on the General Partner's authority to act as
contemplated by this SECTION 14), and shall survive and shall not be affected by
the subsequent death, incapacity, disability, insolvency or dissolution of a
Limited Partner or any delivery by any Limited Partner of an assignment of the
whole or any portion of his or her Units.

                15.     WITHDRAWAL OF A PARTNER.

                (a)     WITHDRAWAL OF GENERAL PARTNER. The Partnership shall be
dissolved upon the withdrawal, resignation, removal, bankruptcy, insolvency or
dissolution of the General Partner, or any other event that causes the General
Partner to cease to be the General Partner of the Partnership, unless the
Partnership is continued pursuant to the terms of SECTION 4(a)(iii). If at the
time of any withdrawal, resignation, removal, bankruptcy, insolvency or
dissolution of the General Partner, or any other event that causes the General
Partner to cease to be the General Partner of the Partnership, there is at least
one remaining general partner of the Partnership, such general partner agrees to
carry on the business of the Partnership. In addition, the General Partner may
withdraw from the Partnership, without any breach of this Agreement, at any time
upon 120 days' written notice to each Limited Partner and each assignee of whom
the General Partner has notice pursuant to SECTION 11. In the event of the
General Partner's withdrawal, resignation or removal from the Partnership, the
General Partner shall be entitled to a redemption of its general liability
interest in the Partnership at its Net Asset Value as of the close of business
on the last Business Day of the month following the date of withdrawal,
resignation or removal. If the General Partner withdraws from the Partnership
and the Partnership's business is

                                      A-14
<Page>

continued, the withdrawing General Partner shall pay all expenses incurred as a
result of its withdrawal.

                (b)     WITHDRAWAL OF LIMITED PARTNERS. The death, incompetency,
withdrawal, bankruptcy, insolvency or dissolution of a Limited Partner or any
other event that causes a Limited Partner to cease to be a limited partner in
the Partnership shall not terminate or dissolve the Partnership, and a Limited
Partner, his or her estate, custodian or personal representative shall have no
right to redeem or value such Limited Partner's interest except as provided in
SECTION 12. Each Limited Partner expressly agrees that in the event of his or
her death, he or she waives on behalf of himself or herself and his or her
estate, and directs the legal representatives of his or her 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. Nothing in this SECTION 15 shall,
however, waive any right given elsewhere in this Agreement for a Limited Partner
to be informed of the Net Asset Value of his or her Units, to receive audited
financial statements and other information from the General Partner or the
Partnership or to redeem or transfer Units.

                16.     STANDARD OF LIABILITY; INDEMNIFICATION.

                (a)     LIABILITY OF THE GENERAL PARTNER. The General Partner
shall have unlimited liability for the repayment, satisfaction and discharge of
all debts, liabilities and obligations of the Partnership to the full extent,
and only to the extent, as required by the terms of this Agreement and the Act.

                (b)     STANDARD OF LIABILITY OF THE GENERAL PARTNER. The
General Partner and its Affiliates shall have no liability to the Partnership or
to any Limited Partner for any loss suffered by the Partnership that arises out
of any action or inaction of the General Partner or its Affiliates if the
General Partner, in good faith, determined that such course of conduct was in
the best interests of the Partnership, the General Partner or its Affiliates
were acting on behalf of or performing services for the Partnership and such
course of conduct did not constitute negligence or misconduct of the General
Partner or its Affiliates.

                (c)     INDEMNIFICATION OF THE GENERAL PARTNER BY THE
PARTNERSHIP. To the fullest extent permitted by law, the General Partner and its
Affiliates shall be indemnified by the Partnership against any losses,
judgments, liabilities, expenses and amounts paid in settlement of any claims
sustained by them in connection with the Partnership; provided, that the General
Partner, in good faith, determined that such conduct was in the best interests
of the Partnership, the General Partner or its Affiliates were acting on behalf
of or performing services for the Partnership and such claims were not the
result of negligence or misconduct on the part of the General Partner or its
Affiliates. The indemnification provided by the Partnership to the General
Partner and its Affiliates hereunder is recoverable only from the assets of the
Partnership and not from the Limited Partners.

                (d)     SECURITIES LAWS VIOLATIONS. Notwithstanding anything to
the contrary contained in SECTION 16(c), the General Partner and its Affiliates
and any Person acting as a broker-dealer shall not be indemnified for any
losses, liabilities or expenses arising from or out of an alleged violation of
federal or state securities laws unless (i) there has been a successful

                                      A-15
<Page>

adjudication on the merits of each count involving alleged securities law
violations as to the particular indemnitee, (ii) such claims have been dismissed
with prejudice on the merits by a court of competent jurisdiction as to the
particular indemnitee or (iii) a court of competent jurisdiction approves a
settlement of the claims against a particular indemnitee and finds that
indemnification of the settlement and related costs should be made. In any claim
for indemnification pursuant to SECTION 16(d)(iii), the party seeking
indemnification shall place before the court the position of the Securities and
Exchange Commission and any other state or applicable regulatory authority with
respect to the issue of indemnification for securities law violations.

                (e)     INSURANCE. The Partnership may not incur the cost of any
insurance that covers the General Partner and that contains coverage for
liabilities as to which the General Partner is prohibited from being indemnified
pursuant to this SECTION 16.

                (f)     ADVANCES. Advances from the funds of the Partnership to
the General Partner or its Affiliates for legal expenses and other costs
incurred as a result of a legal action will be made only if the following
conditions are satisfied: (i) the legal action relates to the performance of
duties or services by the General Partner or its Affiliates on behalf of the
Partnership; (ii) the legal action is initiated by a third party who is not a
Limited Partner or the legal action is initiated by a Limited Partner and a
court of competent jurisdiction approves such advancement; and (iii) the General
Partner or its Affiliates undertake to repay the advanced funds, with interest
from the initial date of such advance, to the Partnership in cases in which they
would not be entitled to indemnification under the standard of liability set
forth in SECTION 16(b).

                (g)     INDEMNIFICATION OF THE PARTNERSHIP BY THE LIMITED
PARTNERS. In the event that the Partnership is made a party to any claim,
dispute or litigation or otherwise incurs any loss or expense as a result of or
in connection with any activities, obligations or liabilities of a Limited
Partner unrelated to the business of the Partnership, such Limited Partner shall
indemnify and reimburse the Partnership for all loss and expense incurred,
including reasonable attorneys' fees in connection therewith.

                (h)     LIMITED LIABILITY OF LIMITED PARTNERS. Each Unit shall
be fully-paid and non-assessable. Except as otherwise provided by law, a Limited
Partner will have no liability in excess of his or her obligation to make
contributions to the capital of the Partnership and the amount of his or her
capital account and accumulated profits.

                17.     AMENDMENTS; MEETINGS.

                (a)     AMENDMENTS WITH CONSENT OF THE GENERAL PARTNER.

                (i)     If at any time during 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 approved by the
        General Partner and by the Limited Partners owning Units representing
        more than 50% of the outstanding Units then owned by Limited Partners;
        provided, that the approval of each affected Limited Partner and
        assignee of whom the General Partner has notice pursuant to SECTION 11
        shall be required to reduce

                                      A-16
<Page>

        the capital account of such Limited Partner or assignee otherwise than
        in accordance with the terms of this Agreement or modify the percentage
        of profits, losses or distributions to which such Limited Partner or
        assignee is entitled hereunder; and provided, further, that the approval
        of all Limited Partners shall be required to modify the provisions of
        this SECTION 17.

                (ii)    Notwithstanding the foregoing, the General Partner may
        amend this Agreement without the consent of the Limited Partners in
        order (i) to clarify any clerical inaccuracy or ambiguity or reconcile
        any inconsistency (including any inconsistency between this Agreement
        and the Prospectus), (ii) to 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,
        (iii) to qualify or maintain the qualification of the Partnership as a
        partnership in any jurisdiction, (iv) to delete or add any provision of
        or to this Agreement required to be deleted or added by the Securities
        and Exchange Commission or any other federal agency or any state "Blue
        Sky" or similar official or otherwise required by law, (v) to delete or
        add any provisions of or to this Agreement that the General Partner
        deems advisable, provided that such amendment is for the benefit of and
        not adverse to the Limited Partners, (vi) to attempt to ensure that the
        Partnership is not treated as an association taxable as a corporation
        for federal income tax purposes, (vii) to attempt 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 Investment Company Act of 1940, as amended, and (viii) to attempt
        to avoid causing the assets of the Partnership from being considered for
        any purpose of ERISA or Section 4975 of the Code to constitute assets of
        any Plan.

                (b)     AMENDMENTS AND ACTIONS WITHOUT THE CONSENT OF THE
GENERAL PARTNER. The following actions may be taken with respect to the
Partnership without the consent of the General Partner if such actions are
approved by the Limited Partners owning Units representing more than 50% of the
outstanding Units then owned by Limited Partners: (i) this Agreement may be
amended, provided, that the consent of the General Partner shall be required for
any amendment that modifies the compensation or distributions to which the
General Partner is entitled or that affects the duties of the General Partner;
(ii) the General Partner may be removed and replaced; (iii) a new General
Partner or General Partners may be elected if the General Partner withdraws from
the Partnership; (iv) any contract with the General Partner or any of its
Affiliates may be canceled without penalty upon 60 days' notice; and (v) the
Partnership may be dissolved.

                (c)     METHODS OF LIMITED PARTNER CONSENT. In any matter
regarding any Partnership action in which consent of a Limited Partner is
required, such consent shall be deemed to have been give if either: (i) such
Limited Partner affirmatively grants such consent in writing; or (ii) such
Limited Partner has been furnished with a written notice of the matter(s) for
which consent is requested and the Limited Partner shall have failed to respond
to such notice within the time period designated in the notice.

                (d)     NAMES AND ADDRESSES OF LIMITED PARTNERS. Any Limited
Partner upon request given to the General Partner shall be entitled to obtain
from the General Partner, upon payment in advance of reasonable reproduction and
mailing costs, a list of the names and

(which shall be mailed by the General Partner to the Limited Partner within 10
Business Days of the receipt of the request); provided, that the General Partner

        matter upon which the Limited Partners may vote pursuant to this
        Agreement or under the Act. Such meeting shall be held at least 30 but

                            SUBSCRIPTION REQUIREMENTS

NOTICE: AN INVESTMENT IN THE FUND IS SPECULATIVE AND INVOLVES A HIGH DEGREE OF
RISK. PLEASE REFER TO THE SECTION OF THE PROSPECTUS ENTITLED "THE RISKS YOU
FACE" FOR A COMPLETE DESCRIPTION OF THE MATERIAL RISKS OF AN INVESTMENT IN THE
FUND.

GENERAL

     To subscribe for units in the Fund, you must:

          -     execute and deliver (to the selling agent who solicited your
                subscription) the subscription agreement and power of attorney
                signature page, and any other required documents (E.G.,
                corporate authorizations); and

          -     deliver to your selling agent a check in the full amount of your
                subscription payable to "S&P Managed Futures Index Fund, LP," or
                authorize a wire transfer in the full amount of your
                subscription in accordance with the instructions set forth in
                the subscription agreement and power of attorney signature page
                (unless you intend to make payment by debiting your brokerage
                account with your selling agent).

     The minimum initial subscription is $10,000, except that with respect to
individual retirement plans the minimum initial subscription is $3,000. Existing
limited partners may make additional investments in the Fund in $2,500 minimums.

     By executing and delivering the subscription agreement and power of
attorney, you irrevocably subscribe for units at $1,000 per unit during the
initial offering period and thereafter at net asset value per unit as of the
first business day of the calendar month in which your subscription is to be
effective (provided the subscription agreement and power of attorney signature
page are received at least five business days (and cleared funds to purchase the
units at least three business days) before the first business day of the
calendar month in which the subscription is to be effective). The general
partner may accept or reject your subscription, in whole or in part, in its sole
discretion. If your subscription is accepted, you agree to contribute your
subscription to the Fund and to be bound by the terms of the limited partnership
agreement. By executing and delivering the subscription agreement and power of
attorney, you will be deemed to have executed the limited partnership agreement.
You will be required to reimburse the Fund and the general partner for any
expense or loss incurred by either the Fund or the general partner as a result
of the cancellation of your units due to your failure to deliver immediately
available funds in the amount of the subscription price.

YOU.

ITEM 17.  UNDERTAKINGS
(a)(1) The undersigned Registrant hereby undertakes to file, during any period
in which offers or sales are being made, a post-effective amendment to this
registration statement:

          (i)   to include any prospectus required by Section 10(a)(3) of the
          Securities Act of 1933;

          (ii)  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. Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high end of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the aggregate, the changes in volume and price represent no more than
          a 20 percent change in the maximum aggregate offering price set forth
          in the "Calculation of Registration Fee" table in the effective
          registration statement;

          (iii) 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.

                                      II-3
<Page>

(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) 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.

(b) Insofar as indemnification from liabilities under the Securities Act of 1933
may be permitted to the directors, officers and controlling persons of the
Registrant pursuant to the provisions described in Item 14 above, or otherwise,
the Registrant had been advised that in the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 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 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 the court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
