S&P MANAGED FUTURES INDEX FUND, LP
(A DELAWARE LIMITED PARTNERSHIP)

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1.    NATURE OF BUSINESS AND ORGANIZATION

      ORGANIZATION - S&P Managed Futures Index Fund, LP (the "Fund") was
      organized as a limited partnership on May 13, 2003 under the Delaware
      Revised Uniform Limited Partnership Act, as amended, and started
      operations on March 15, 2004. In accordance with the Amended and Restated
      Limited Partnership Agreement, the Fund is organized as a single series of
      limited partnership units (the "Units") which are offered in two classes -
      Class 1 and Class 2 (each, a "Class"). Prior to July 1, 2005, Class 1 and
      2 were called Class A and B, respectively.

      RefcoFund Holdings, LLC is the General Partner of the Fund ("RFH" or the
      "General Partner"). The General Partner has the sole authority and
      responsibility for managing the operations of the Fund and directing the
      investment of the Fund's 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.

      The Fund is designed to seek investment returns that substantially track
      the Standard & Poor's Managed Futures Index (the "Index"), before expenses
      of the Fund. 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 (the "Index SPC"), which is a Cayman
      Islands segregated portfolio company. The Index SPC is designed to track
      the Index, and thus provide the Fund's limited partners with exposure to a
      broad cross section of systematic managed futures strategies through a
      single investment. The Index SPC allocates its assets to portfolio
      managers (the "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. Standard &
      Poor's has granted a license to PlusFunds and RFH to utilize the Index in
      connection with the Index SPC and the Fund.

      The Fund will be terminated and dissolved upon the occurrence of any one
      of the following events: (1) limited partners owning more than 50% of the
      outstanding Units voting to dissolve the Fund; (2) the General Partner
      ceasing to be general partner and no new general partner being appointed;
      or (3) the continued existence of the Fund becoming unlawful.

      BISYS-RK Alternative Investment Services, Inc. ("BISYS-RK") acts as the
      administrator, transfer agent and registrar of the Fund. BISYS-RK also
      provides certain accounting and administrative services to the Fund.

      The Units are offered by Refco Securities, LLC (the "Selling Agent"), an
      affiliate of the General partner and a broker-dealer registered with the
      United States Securities and Exchange Commission, and by any additional
      selling agents who may be engaged from time to time on behalf of the Fund.

2.    SIGNIFICANT ACCOUNTING POLICIES

      The following is a summary of significant accounting policies consistently
      followed by the Fund.

      BASIS OF PRESENTATION - The accompanying unaudited financial statements of
      the Fund have been prepared in accordance with accounting principles
      generally accepted in the United States of America for interim financial
      information and with the instructions to Form 10-Q and Rule 10-01 of

                                        7
<Page>

      Regulation S-X. Accordingly, they do not include all of the information
      and footnotes required by accounting principles generally accepted in the
      United States of America for complete financial statements. In the opinion
      of management, all adjustments (consisting only of normal recurring
      adjustments) considered necessary for a fair statement of the financial
      condition and results of operations of the Fund for the period presented
      have been included.

      SECURITIES VALUATION - The economic interest of investors in the Units
      ultimately resides in the Index SPC as allocated to the Portfolio Managers
      of the Index. This investment is valued on a semi-monthly basis and
      represents the net asset value of the assets allocated to the Portfolio
      Managers. Such net asset value is derived after valuing the assets
      allocated to the Portfolio Managers and deducting expenses at the Index
      SPC level, including management fees and incentive allocations to the
      Portfolio Managers. The Fund is allocated realized and unrealized gains
      and net investment income from the Index SPC in proportion to its
      ownership in the Index SPC. This is reflected in the statement of
      operations as "increase (decrease) in equity in Index SPC."

      Management fees payable to the Portfolio Managers range from 1.00% to
      2.50% per annum of the assets allocated to a Portfolio Manager. Each
      Portfolio Manager is eligible to receive performance based compensation of
      15% to 25% of net trading gain.

      INVESTMENT TRANSACTIONS - The Fund records subscriptions and redemptions
      related to its investment in the Index SPC on the transaction date.

      CASH - The Fund considers all highly liquid investments with a maturity of
      three months or less when purchased to be cash and cash equivalents.

      EXPENSES - In accordance with the Amended and Restated Limited Partnership
      Agreement, the Fund will be charged for certain expenses 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.

      All expenses are recorded on an accrual basis.

      USE OF ESTIMATES - The preparation of financial statements in conformity
      with accounting principles generally accepted in the United States of
      America requires management to make estimates and assumptions that affect
      the amounts reported in the financial statements and accompanying notes.
      Actual results could differ from these estimates.

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

3.    SUBSCRIPTIONS AND REDEMPTIONS

      Units are issued upon subscription into and redeemed through redemption
      from the Fund.

      Subscriptions for either Class may be made as of the 1st and 16th day of
      the month (the "Offering Date") at net asset value per Unit. If either day
      is not a business day, then the subscription may be made as of the next
      business day. The net asset value per Unit of each Class is determined by
      dividing the net assets of each Class by the number of Units of that Class
      outstanding on the date the calculation is being performed.

                                        8
<Page>

      The Units may generally be redeemed as of the 15th day and the last day of
      each calendar month, subject to certain restrictions and qualifications,
      upon at least 10 business days' prior written notice to the General
      Partner. 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 may not be able to make timely payments
      with respect to redemptions due to the Fund's inability to liquidate its
      investment in the Index SPC on a timely basis. 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.

      A redemption fee payable to RFH of 2% of the net asset value per Class 1
      Unit applies if a Class 1 Unit is redeemed within 12 months of its
      original purchase. However, the redemption fee is reduced by 1/24th of 2%,
      or 0.08333%, on the 15th day of the month and the last business day of
      each month following the date the units were purchased. The Class 2 Units
      are not subject to a redemption fee. Class A units purchased on or after
      June 30, 2004 and prior to July 1,2005 will pay a redemption fee of 3% of
      net asset value per Class 1 unit if these units are redeemed within 12
      months of the date of their original purchase

4.    RELATED PARTY TRANSACTIONS

      Refco Securities, LLC, the Selling Agent of the Fund, is an affiliate of
      the General Partner. Refco LLC, an affiliate of the General Partner and
      the Selling Agent, acts as futures commission merchant 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, Ltd., also an affiliate of RFH, acts as the dealer for the
      underlying investments of the Index SPC for currency trading.

                                        9

      The Fund's selling agents are advanced from the General Partner an initial
      service fee equal to 2% of the purchase price per Class 1 Unit at the time
      that the Class 1 Unit is sold for services provided during the first 12
      months of ownership. The General Partner is reimbursed monthly by the Fund
      over the following 12 - month period. Class 1 Units purchased on or after
      June 30, 2004 and prior to July 1, 2005 pay an initial service fee to the
      General Partner of 2.9% annually of net assets. In the event Class 1 units
      are redeemed within the 12 - month period following the purchase, the
      Fund's obligation to reimburse the General Partner terminates and no
      further payments are made. Prior to July 1, 2005, the Fund's selling
      agents received from the General Partner upfront selling commissions equal
      to 3% of the purchase price of the Class 1 Units and ongoing service fees
      of 2% commencing in the 13th month after the sale. After July 1, 2005, the
      Fund will also pay to the selling agents with respect to the Class 1
      Units, ongoing service fees beginning in the 13th month following the
      purchase of Class 1 Units equal to 0.167% of the Class 1 Units' month-end
      net assets (a 2.00% annual rate). The Class 2 Units are not subject to any
      initial or ongoing servicing fees. No selling commissions will be paid
      from the proceeds of subscriptions.

      The following is a summary of commissions, initial service fees and
      redemption fees earned by RFH:

      Refco Group Ltd., LLC, the parent of the General Partner, paid the
      organizational and initial offering expenses.

      RFH receives a management fee of 1.25% annually of the Class 1 and 2 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 in its
      sole discretion. Prior to July 1, 2005 RFH received management fees of
      4.15% and 2.15% annually of the Class 1 and Class 2 Units, respectively.

      The Amended and Restated Limited Partnership Agreement and/or guidelines
      of state securities regulators limit the fees that are paid by the Fund
      (the "Expense Cap"). From commencement of operations through September 30,
      2005 aggregate annual fees and expenses based on the Fund's net assets
      could not exceed 6% of net assets per year (1/2 of 1% per month). This
      Expense Cap included management fees and customary and routine
      administrative expenses of the Fund but did not include legal and
      accounting expenses or extraordinary expenses.

      Effective July 1, 2005, the Fund implemented the following voluntary
      expense caps: the management fee payable to the General Partner and the
      operating expenses (excluding service fees) of the Fund are limited to an
      aggregate of 1.70% in respect to the Class 1 and Class 2 Units calculated
      on the net assets before the application of fees. To the extent that the
      monthly management fee payable to the General Partner and operating
      expenses (excluding service fees) of the Fund exceed the above mentioned
      limits, the General Partner will waive its management fee of 1.25% with
      respect to the Class 1 and 2 Units. If, after the deduction of the
      management fee, the expenses of the Fund remain above 1.70% for the Class
      1 and Class 2 Units, the General Partner will reimburse the Fund for such
      expenses to bring them within the limits stated above. Prior to July 1,

                                       10
<Page>

      2005, Class 1 and Class 2 Units were subject to a voluntary expense cap of
      4.95% and 2.95%, respectively, calculated on the net assets before the
      application of fees.

      The reimbursements for the periods ended September 30, 2004 and 2005 are
      set forth on the Statement of Operations.

      As of December 31, 2004 and September 30, 2005, the General Partner held
      491.8988 Class 2 Units of the Fund totaling $450,387 and 697.8224 Class 2
      Units of the Fund totaling $594,845 respectively.

5.    COMMITMENTS AND CONTINGENCIES

      In the normal course of business, the Fund enters into contracts that
      contain a variety of representations and warranties and which contain
      general indemnification provisions. The Fund's maximum exposure under
      these arrangements is unknown as the potential exposure involves future
      claims that may be made against the Fund. Based upon the prior experience
      of the General Partner, the General Partner expects the risk of loss to be
      remote.

6.    DERIVATIVE FINANCIAL INSTRUMENTS

      By investing in the Index SPC, the Fund will be subject to all of the
      risks associated with the Index SPC's investments and trading. The Index
      SPC may invest in derivative instruments, which include futures, forwards,
      swaps or options, or other financial instruments with similar
      characteristics. All derivatives are reported at fair value and changes in
      value are reflected in the net asset value of the Index SPC.

      Market Risk - Derivative instruments involve varying degrees of
      off-balance sheet market risk. Changes in the level or volatility of
      interest rates, foreign currency exchange rates or the market values of
      the financial instruments or commodities underlying such derivative
      instruments may result in changes in the Index SPC's net unrealized profit
      (loss) on such derivative instruments. The Index SPC's exposure to market
      risk is influenced by a number of factors, including the relationships
      among the derivative instruments held by the Index SPC as well as the
      volatility and liquidity in the markets in which such derivative
      instruments are traded.

      Credit Risk - The Index SPC has credit risk associated with counterparty
      non-performance.

      The risks associated with exchange-traded contracts are typically
      perceived to be less than those associated with the over-the-counter
      transaction (non-exchange traded), because exchanges typically provide
      clearing house arrangements in which the collective credit (which is, in
      some cases, limited in amount) of the members of the exchange is pledged
      to support the financial integrity of the exchange. In over-the-counter
      transactions, on the other hand, traders must rely solely on the credit of
      the respective individual counterparties. If the Index SPC's clearing
      broker becomes bankrupt or insolvent, or otherwise defaults on its
      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 the clearing broker, 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 was held by the clearing
      broker. See Note 8, "Subsequent Events" for more information about the
      Index SPC's futures clearing merchant.

      vehicles that were recorded by the Index SPC.

8.    SUBSEQUENT EVENTS

      On October 10, 2005, Refco, Inc., the ultimate parent of RFH, announced
      that it had discovered through an internal review a receivable owed to
      Refco, Inc., by an entity controlled by Phillip R. Bennett, the then Chief
      Executive Officer and Chairman of the Board of Directors of Refco, Inc.,
      in the amount of approximately $430 million. Mr. Bennett has been charged
      with securities fraud in connection with this matter and various actions
      have been filed against Refco, Inc. Thereafter, on October 13, 2005,
      Refco, Inc., announced that the liquidity within Refco Capital Markets,
      Ltd. ("RCM") was no longer sufficient to continue operations, and that RCM
      had imposed a fifteen (15) day moratorium on all of its activities in an
      attempt to protect the value of that enterprise.

      On October 18, 2005, Refco, Inc. and RCM filed for bankruptcy protection
      in the Southern District of New York. None of the Fund, RFH or the Index
      SPC, were covered by the filing.

      Although the Fund's assets are not held directly with Refco, Inc., one of
      Refco, Inc.'s affiliated entities, Refco, LLC, did indirectly serve as the
      futures commission merchant through the Fund's investment in the Index
      SPC. Refco, LLC was not covered by the bankruptcy filing. In addition, a
      portion of the Fund's assets (less than 3%, based upon net assets as of
      October 13, 2005) was indirectly exposed to RCM through a number of
      foreign currency contracts held within the portfolios of the Index SPC.
      While RCM has unwound any outstanding foreign currency contracts with the
      Index SPC, the Index SPC does not expect to be able access those assets in
      the near future.

      In light of the events outlined herein, the Index SPC moved the majority
      of the Fund's assets from Refco, LLC to Lehman Brothers, Inc. and its
      affiliated entities ("Lehman") to act as futures clearing merchant. On or
      about October 17, 2005, the Index SPC had transferred the majority of its
      assets to Lehman. The Index SPC is in the process of transferring any
      remaining assets held at Refco LLC to Lehman in due course. Pending the
      resolution of the Fund's claim against RCM, the Fund will no longer have
      assets on deposit with RCM.

      RFH does not believe that the bankruptcy filings of Refco, Inc. and RCM
      will have a material impact upon the operations of the Fund or the Index
      SPC, or either's ability to satisfy a request for redemption. In this
      regard, the operations of the Fund and the Index SPC, including the
      trading activities of the underlying asset managers, have continued with
      minimal interruption. The Index SPC has informed the Fund that, with
      respect to redemptions made as of October 14, 2005 and thereafter, the
      Index SPC will continue to make payment in the ordinary course with
      respect to 95% of the proceeds of such redemptions, while reserving the
      payment of the remaining 5% for up to twenty business days prior to final
      distribution. So long as the Index SPC continues to make redemption
      payments in accordance with its Memorandum and Articles of Association,
      the Fund will continue to make redemptions payments in accordance with the
      Fund's Disclosure Document and organizational documents.

      Generally, investors in the Fund may redeem units as of (i) the 15th day
      of any calendar month (or the business day prior to the 15th day of the
      month if the 15th day of the month is not a business day), and (ii) the
      last business day of any calendar month; provided, however, that, in
      either instance, RFH receives 10 business days' prior written notice of an
      investor's intent to redeem.

      Effective August 8, 2005, Mr. Philip Silverman resigned as the Secretary
      and Chief Financial Officer of RFH. Effective October 13, 2005, the
      composition of the Managers of RFH has changed as Mr. Philip R. Bennett
      was removed as a Manager of the General Partner and Mr. Richard C. Butt,
      President of RFH , and Ms. Annette A. Cazenave were appointed Managers of
      RFH. On November

                                       13
<Page>

      18, 2005, Mr. Keith D. Kemp resigned and on November 21, 2005 Mr. Eric A.
      Simonsen was appointed as Chief Financial Officer of RFH.

      On November 10, 2005, Man Group PLC signed an initial agreement to
      purchase certain assets, and assume certain liabilities, of Refco LLC and
      certain assets of other subsidiaries of Refco, Inc. The transaction was
      closed on November 25, 2005 and Refco LLC filed for bankruptcy under
      Chapter 7 of the United States bankruptcy law. Neither RFH nor the assets
      of RFH have been included in that purchase agreement. While actively
      exploring various strategic options including the sale of RFH to a third
      party or seeking to approve a new General Partner, RFH management cannot
      predict whether these efforts will be successful. If an acceptable
      strategic option is not identified in the foreseeable future, RFH may need
      to resign as General Partner of the Fund and the Fund may need to be
      terminated and dissolved.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

INTRODUCTION

      The Fund is a managed futures investment fund designed to seek returns
      that substantially track the Index, before expenses of the Fund.

      The Fund pursues its investment objective by investing in the Index SPC,
      which currently allocates investments to 14 commodity trading advisors
      ("Portfolio Managers"). All of the Index SPC's Portfolio Managers employ
      systematic trading approaches that are mostly technical trend-following in
      nature and are designed to collectively deliver returns broadly
      representative of systematic managed futures programs, and therefore do
      not have specific return or volatility targets. Portfolio Managers
      employing technical trend-following approaches generally take positions
      based on computer-generated models to identify trades, determine the size
      of positions, and to control ongoing portfolio exposure to specific
      markets.

      The Standard & Poor's Managed Futures Index Committee (the "Index
      Committee") is responsible for overseeing the methodology, constituent
      selection and operations related to the Index. Index constituents are
      selected based on multiple factors including representativeness of managed
      futures in general, the quality of the manager's trading program, the
      program's risk/return profile, performance during selected time frames and
      market conditions, and the type of market instruments held. Other, less
      technical factors are included in the selection process such as trading
      manager reputation, experience, training, stability and quality of
      organization, as well as a minimum track record length (generally 3 years)
      and quantity of assets under management. PlusFunds Group, Inc.
      ("PlusFunds") acts as investment manager of the Index SPC. The Portfolio
      Managers in the Index SPC receive allocations that generally track the
      Index and are initially weighted equally on a dollar basis, and rebalanced
      annually in January, or as otherwise needed.

CAPITAL RESOURCES

      The Fund is designed to raise additional capital only through the sale of
      limited partnership interests in the Fund (the "Units") pursuant to the
      continuous offering of the Units pursuant to registration statements filed
      on Form S-1 with the Securities and Exchange Commission (the "SEC") and
      does not intend to raise any capital through borrowing. The General
      Partner does not plan to invest the Fund's assets directly other than in
      the stated investment objective, but the General Partner may invest funds
      temporarily in U.S. government obligations, money market accounts, or
      other short-term interest-bearing accounts. Additionally, the General
      Partner may borrow money on an unsecured or secured basis for cash
      management purposes, and will pay interest on such activities.

                                       14
<Page>

LIQUIDITY

      An investment in the Fund is not liquid as there is no secondary market
      for the Units. The Units may be redeemed only as of the fifteenth and the
      last business day of the calendar month by providing at least ten business
      days' prior notice. If the 15th day is not a business day, than the
      redemption shall take place on the immediately following business day. In
      addition, 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's assets.

      While the Fund does not invest directly in futures contracts, it possesses
      indirect liquidity risk through its investment in the Index SPC as
      described below. Most U.S. futures exchanges limit fluctuations in some
      futures and options contract prices during a single day by regulations
      referred to as daily price fluctuation limits or daily limits. During a
      single trading day, no trades may be executed at prices beyond the daily
      limit. Once the price of a contract has reached the daily limit for that
      day, positions in that contract can neither be taken nor liquidated.
      Futures prices have occasionally moved to the daily limit for several
      consecutive days with little or no trading. Similar occurrences could
      prevent the investment manager of the Index SPC from promptly liquidating
      unfavorable positions and subject the Index SPC to substantial losses that
      could exceed the margin initially committed to those trades. In addition,
      even if futures or options prices do not move to the daily limit, the
      Index SPC may not be able to execute trades at favorable prices, if little
      trading in the contracts is taking place. Other than the limitations
      described above, the Index SPC's assets are expected to be highly liquid.

OFF-BALANCE SHEET ARRANGEMENTS

      The Fund does not have any off-balance sheet arrangements.

RESULTS OF OPERATIONS

      The Class 1 Units returned (8.29%) year-to-date and 2.65% for the
      three-month period ended September 30, 2005, net of fees and expenses. The
      Class 1 Units returned (16.82%) from March 15, 2004 (Commencement of
      Operations) to September 30, 2004, and 0.32% for the three-month period
      ended September 30, 2004, net of fees and expenses.

      The Class 2 Units returned (6.90%) year-to-date and 3.17% for the
      three-month period ended September 30, 2005, net of fees and expenses. The
      Class 2 Units returned (16.14%) from March 15, 2004 (Commencement of
      Operations) to September 30, 2004, and 0.82% for the three-month period
      ended September 30, 2004, net of fees and expenses.

      QUARTER AND NINE MONTHS ENDED SEPTEMBER 30, 2005

      During the quarter ended September 30, 2005, of the 14 managers in the
      Index, 11 managers had positive returns, with underlying managers' returns
      ranging from a negative 14.18% to a positive 47.89%. During the nine
      months ended September 30, 2005, of the 14 managers in the Index, 5
      managers had positive returns, with underlying managers' returns ranging
      from a negative 21.81% to a positive 8.77%.

      After posting its seventh consecutive year of positive returns, the Index
      began the 1st quarter of 2005 with a loss of 6.32% in January as market
      participants reversed their views on the viability of the U.S. economy and
      aggressively bid up the U.S. dollar versus other currencies. As background
      to the reversal, the U.S. dollar collapsed after the U.S. presidential
      election in November 2004, with the consensus view holding that budget
      deficits, trade deficits, and trade flows would remain in poor condition
      for the foreseeable future thus making the U.S. economy and its currency
      appear less

                                       15

      inviting as investments. Government bonds were down slightly for the
      period ending March 31, 2005 as the long end of global yield curves
      steepened in February at least partially on account of testimony before
      Congress of Alan Greenspan, Chairman of the Federal Reserve Board,
      regarding business activity level. However, going into the end of the 1st
      quarter the increase in the U.S. trade deficit, which was the second
      largest in history-helped push U.S. bond prices even lower to a level of
      10930. Although volatile, metals rallied through the end of the quarter,
      helped by a recovery in copper and silver, which were approaching recent
      highs based on a tighter industry supply outlook and a weakening U.S.
      dollar. Additionally, energy prices continued to move higher throughout
      the 1st quarter of 2005 as Northeast U.S. temperatures remained cold in
      January and February and the prospect that Organization of the Petroleum
      Exporting Countries ("OPEC") would endorse production cuts appeared more
      likely. As a result, crude oil moved from intra-month lows near U.S.
      dollar $42 at the beginning of January to end March slightly over the U.S.
      dollar $56 level. Mid-way through January, U.S. equity markets led global
      equity indices higher on increased news of profitability, increased
      manufacturing orders, and upwardly revised Gross Domestic Products numbers
      for the fourth quarter of 2004 in the U.S. However, throughout February
      and March, unrelenting energy prices and lower than expected earning
      reports put downside pressure on the equity markets.

      The second quarter of 2005 continued to be a difficult period of time for
      the Index. Performance of the Index improved in May and June. This
      three-month period was defined by major reversals across most major
      sectors especially in the energies, the metals and the equity indices.
      This period of time was also marked by some market sectors finding
      direction in May with follow through in June, allowing for many trends to
      remain intact. In April, the equity indices experienced a strong sell-off,
      prompted by weaker U.S. economic data and also concerns about the impact
      of higher energy prices paired up with poor consumer demand data.
      Additionally, the metals sector found support as evidence of a weakening
      U.S. economy emerged. The energy markets, principally crude oil, put in
      new highs at the start of April and experienced a major downward
      correction as data showed a large increase in crude oil inventories. May
      seemed to bring some stability to the performance of the Index as U.S.
      bond and short-term interest rate markets were supported by stable
      inflation data in the U.S. Equity indices found support on the stable
      inflation outlook in the U.S. and Europe amid lower energy prices. The
      month of June brought some greater stability, as the markets in general
      seemed to enjoy favorable economic data, particularly from the U.S.
      resulting in many markets to continue to trend into the end of the month.
      Equity markets remained well supported, helped by favorable global bond
      markets despite rising energy prices, coupled with the U.S. dollar
      strength, as the U.S. economy continued showing signs of non-inflationary
      growth. Lastly, the global bond markets ended the month stronger despite
      the intra-month sell off caused by higher energy prices. The result of all
      this activity was positive performance for the Index of 1.86% in the month
      of June.

      Based on the above market activity, the Index took losses in global bond
      and short-term interest rate sectors, with profits in the equity indices,
      foreign exchange and energy sectors.

      Performance for the 3rd quarter 2005 was a positive 3.17%. The markets in
      July were dominated by major political and economic news with stock
      indices performing strongest, as global economic sentiment remained
      robust. Positive returns on equities and energy were countered by losses
      in fixed income, short-term interest rate and currency trading. Currency
      trading proved volatile during the month as the market digested the news
      of the Chinese Yuan revaluation, along with the move to a managed floating
      exchange rate regime. The U.S. Dollar against the Euro traded in a range
      between 1.1870 and 1.2250 while the U. S. Dollar moved higher against the
      Yen closing at 112.50. The terrorist attacks in London had an impact on
      markets that proved short-lived. Fixed income markets sold off after
      Chairman Greenspan's testimony, which focused on the robustness of the
      U.S. economy and the strong domestic housing market while, the Japanese
      bond markets weakened as a result of the Chinese revaluation. The energy
      sector, while remaining volatile, continued to move higher with Crude Oil
      reaching $61.90 per barrel. Equity markets were helped by stronger
      earnings

                                       16
<Page>

      as the S&P reached a new high for the year. The metals markets
      (principally gold) consolidated recent moves higher while grains, meats
      and softs provided mixed results on the month. Rising energy prices
      continued to dominate market activity in August. The extent of the
      diversification of the Index across sectors was highlighted as strong
      returns from long energy positioning, fixed income and equity indices more
      than covered losses in the currency, short-term financials and grain
      sectors. Energy trading proved to be the main driver of performance in
      August as Crude Oil hit $70 a barrel. The acceleration in prices towards
      month-end was driven by Hurricane Katrina and its impact on the U.S.
      markets. Bond trading was positive as bullish risk grew over the month in
      response to higher energy prices while rallies in short-term interest
      rates caused losses. Currency trading for the majority of managers in the
      Index was difficult as reversals in the Euro and Swiss Franc led to
      losses. Equity markets were quiet and off their highs except for the
      Nikkei which rallied strongly. Precious metals trading saw Gold breaking
      to the upside, to approximately US$450 before trading back into recent
      ranges, while base metals continued to remain strong. Losses in grains
      (corn, soybeans, wheat) trading were matched by profits in the softs
      (coffee, sugar, cocoa) while meats (lean hogs, feeder cattle, pork
      bellies) were flat on the month. September saw volatile energy prices
      continue to dominate market activity in the aftermath of Hurricane Katrina
      and Rita. The benefit of the fund's diversification across sectors was
      evident as long positioning in energy, equity indices, currencies and
      metals markets provided strong returns while bond and interest rate
      markets underperformed as the Federal Reserve continued on its tightening
      path. Foreign exchange markets witnessed a strong rally in the U. S.
      Dollar against major currencies, the USD/Euro moved from 1.26 to below
      1.20 as a stalemate emerged after German elections. The stronger U.S.
      Dollar also gained against the Japanese Yen to post a new high for the
      year above 114. Energy markets delivered mixed performance highlighted by
      a surge in natural gas prices, caused by disruptions to refineries. Bond
      and interest rate futures in the U.S. moved lower as the Federal Reserve
      continued on its tightening path despite the effects of Hurricane Katrina.
      The sell off in the U.S. interest rate markets pushed global interest
      rates higher as signs of emerging inflation through higher energy prices
      affected markets. Equity markets moved higher on the month with Europe and
      Japan out-performing U.S. markets. Metal markets moved higher on the month
      as gold broke out to the upside breaking $470 while base metals remained
      well supported. Commodity trading delivered strong returns from long sugar
      positions while grains and meats were also positive.

      QUARTER ENDED SEPTEMBER 30, 2004 AND THE PERIOD FROM MARCH 15, 2004
      (COMMENCEMENT OF OPERATIONS) TO SEPTEMBER 30, 2004

      Of the 14 Portfolio Managers in the Index, only 3 were profitable in
      March. Most sectors traded had an extremely volatile month, with
      individual markets such as equities, energy, and currencies accelerating
      in one direction, then aggressively reversing course without warning. Of
      the 8 pure trend-followers, 6 had negative returns and amongst the pattern
      recognition managers, 5 of 6 had negative returns. Most of the losses in
      March were attributable to trading in 3 sectors. In currencies, the Index
      had losses in the Yen market as short positions that had been developed in
      a long-standing down trend in that currency were caught in a late month 7%
      rally, with the exchange rate moving from a price level of 112 Yen per
      U.S. dollar to close the month at 104 Yen per U.S. dollar. In stock
      indices, the Index had losses from a mid-month correction, where the S&P
      500 Index, for example, moved from 1,157 to 1,091, losing approximately 6%
      in a 2-week time frame. Finally, the Index had losses in the energy
      sector, where the Index's long positions in crude oil had a late month
      correction, falling almost 5% in the last 8 trading days of the month.
      Losses in these Sectors were partially offset by gains in other sectors,
      where the Index benefited from long positions in natural gas and
      agricultural markets, which both had run-ups approaching 7% during March.

      All asset classes in the Fund were volatile during April 2004 as market
      participants reacted to improving economic news coming out of the United
      States. The Fund had mixed but overall negative results, with currency and
      financial components deteriorating as long standing trends it was
      profiting from reversed course on signs that the U.S. economy is
      improving.

                                       17
<Page>

      Most of the losses came from the financial sector, specifically by losses
      in bonds, which were mainly driven by long positions in U.S. treasuries
      that were hit by a 6% reversal by traders dumping bonds in anticipation of
      higher interest rates. Long positions in short-term Euro-denominated
      interest rate instruments also helped depress the Fund's returns. Federal
      Reserve Bank statements suggested the U.S. economy was gaining traction as
      jobs reports were starting to show more favorable numbers and pricing
      power was becoming more apparent. This in turn helped fuel concern over
      increasing inflation pressure and the likely response by the Federal
      Reserve Bank to increase interest rates, which made existing bond yields
      look less attractive than new bond instruments issued in a higher interest
      rate environment.

      Losses were derived from currencies where the Fund was short the U.S.
      dollar against European, Canadian, and U.K. currencies. Most major foreign
      currencies fell by upwards of 5% versus the U.S. dollar on a month-to-date
      basis. The U.S. dollar gained against the Euro in particular after a
      closely followed German Consumer Investor Report showed that economic
      growth was only going to be 1.5% this year, which was perceived by traders
      as further opening the door to an interest rate cut by the European
      Central Bank. In addition, the interest rate increases by the Bank of
      England were perceived as having quelled inflation and signs show the U.K.
      economy may be cooling as well. Combining this news with bullish economic
      reports from the U.S. made the U.S. appear as a more favorable place to
      invest, and thus drove up the U.S. dollar against other currencies.

      By examining macro-economic reports in May, it became apparent that market
      participants were reacting on almost a "day-to-day" basis, making tactical
      maneuvers in reaction to news reports regarding inflation, employment, and
      interest rate reports, as well as commodity price changes and geopolitical
      events. Continuing the theme of April, economic conditions were
      transitioning from the deflationary effect of a global recession to a
      re-inflation theme that resulted from unusually accommodative monetary and
      fiscal policy in the U.S., Europe, and Asia. Although market participants
      broadly agreed on the evidence of this secular trend, there was
      disagreement over the timing of its effects on individual asset classes.
      Following April's sharp drop in bonds in anticipation of increasing rates,
      economic reports in May were somewhat mixed, and market participants
      reacted by trading the "news of the day", which resulted in bonds
      reversing course from a downward trajectory formed in May. Prices
      reversed, however, in mid-May on various news points including OPEC's
      pledge to increase oil output to help restrain record-breaking oil prices
      which would have a deflationary effect on yields and traders rotated back
      into Bonds partially in response. With respect to currencies, the major
      trend coming out of April was the U.S. dollar's turnaround as it gained
      strength from the prospect for higher interest rates that would make it
      more attractive and a medium of exchange to benefit from higher yielding
      investments in the U.S. The U.S. dollar continued to gain strength until
      the middle of May then fell as market participants rotated into gold as a
      flight-to-quality response that drove gold prices up 5% in the last 2
      weeks of May from 377 to 396. Gold was driven up partially in response to
      news of the assassination of the President of the Iraqi Governing Council
      on May 17 and assorted terrorist attacks in Saudi Arabia, which raised
      more doubts on prospects for stability in that region and additionally by
      the sheer frustration of market participants to find a stable store of
      value during May. For the full month of May, U.S. Treasury Bonds were
      virtually unchanged; the U.S. dollar lost about 2% on average vs.
      developed currencies, crude oil rose about 7%, and gold rose about 3%. All
      of these markets traded in volatile ranges for the month.

      The Fund's medium-term trend following managers were hurt the most during
      the month as their models showed strong conviction in the positions
      developed in April and as a result traders added to their short bond
      positions and long U.S. Dollar positions. These managers returned between
      -3.0% to -5.0% for the month. In contrast, those managers engaged in
      long-term trend-following actually posted flat or positive returns for the
      month as their systems had not turned as quickly and thus never fully
      built up positions that got whipsawed in May. These managers posted
      between -0.5% and +0.2% returns for the month. In addition, those managers
      employing shorter-term pattern-recognition strategies also posted flat or
      positive returns as they benefited from volatile sideways

                                       18
<Page>

      markets that were exhibited in May. These managers posted between -1.5%
      and +4.0% returns for the month. In contrast to bonds and currencies that
      caused most of the losses in May, crude oil prices displayed a forceful
      up-trend that helped diminish portfolio losses during the month as a broad
      set of managers had positive exposure to this market.

      During the month of June all managers had negative returns, with long-term
      trend-followers as well as traders with short-term systems contributing
      equally to the negative results. Building on the story from May, most
      major markets traded experienced volatile sideways price activity, whereby
      markets displayed a general lack of directional activity on a full month
      basis but developed jagged patterns on a daily and weekly basis. Although
      it is rare for so many markets to fall into this pattern simultaneously,
      we should note the unusual circumstances market participants encountered
      as they digested the full range of questions relating to interest rate
      changes, geo-political events, economic growth, and inflation, to name
      only a few. Trend followers were again caught on the defensive because
      they had to balance the need to liquidate positions and shield themselves
      from temporary losses against the probability that a short term
      directional move in a given market will indeed turn into a profitable
      trend.

      The geo-political and economic environment in June did not provide
      substantial reasons for trending in many markets and as a result,
      strategies relying on momentum to generate alpha, such as Trend following,
      had a difficult time. Specific to the sectors traded in the Fund, losses
      were incurred primarily in energy markets where substantial positions were
      built up as crude oil trended higher over the last year, but dramatically
      reversed in June, falling from $42/barrel at the beginning of the month to
      $35/barrel by month-end on news of increased OPEC production. In bond
      markets, European- and U.S.-based markets declined through the first 2
      weeks of the month attracting additional short positions from the fund's
      traders, only to reverse course mid month with nearly a 3 point move
      higher in the U.S. 10-Year Notes, for example, as market participants
      reacted to labor market news in the U.S. and speculation on the magnitude
      of the NY Federal Reserve Bank's change in interest rate targets. Losses
      were also incurred in currency markets where the U.S. dollar staged a
      1-month run-up against the Euro and British Pound but did so with extreme
      intra-day volatility where moves approaching 2-points in the Euro were
      common on a daily basis. In reaction to these adverse moves, traders were
      proactive in reducing exposure in losing areas. In energy, for example,
      exposure was reduced by about 40% since June 1 as a result of
      deteriorating market activity. In short Yen positions, where a large
      portion of currency losses occurred, positions were cut by 50% as risk
      management protocols were activated.

      In contrast to these markets, gains from short positions in interest rates
      helped to offset losses elsewhere as these markets are providing one of
      the few quality trending areas from which to profit. Smaller gains were
      also drawn from cotton, cattle, and wheat futures and to a lesser extent
      in frozen orange juice and cocoa markets, as trends developed based on
      supply/demand imbalances and weather-based data.

      In July, 12 managers had negative returns, with returns ranging from -6%
      to +7% and longer-term trend-followers ranking at the top. Losses were
      greatest in financials, including stock indices and currency markets.
      Specifically, long positions in US T-Bonds, Euro/Dollar, and Gold hurt
      performance as the up-trends formed by these markets in June broke apart
      into a volatile sideways trading range last month. Conversely, large gains
      were harvested from Crude Oil and Natural Gas, as both markets developed
      pronounced up-trends, as well as in Agriculturals such as Wheat, Corn, and
      Sugar. Smaller profits were gained in the Soybean market as we caught part
      of the 50% drop in that market in July, which occurred due to beneficial
      weather forecasts and overhead supply in the marketplace. Financial
      markets are still affected by concerns over the viability and speed of a
      global economic recovery along with the threat of terrorism and
      interruption of Crude Oil supplies. As a result of negative performance
      over the last several months, the Index is in a drawdown of about -20%.
      The market background consists of 3 specific phases. First, in January and
      February 2004 the Index accumulated gains generated at the end of
      multi-year trends in Bonds, U.S. Dollar, and Crude

                                       19
<Page>

      Oil. Second, the Index lost ground in April as trend-followers generated
      disappointing returns because the large multi-year trends came to an end
      and started reversing in a volatile manner. Third, from May 2004 to July
      2004, almost every market went into a very unusual "whipsaw" pattern where
      false break-outs occurred on both very short and medium time frames luring
      both longer-term and shorter-term trend-followers into building positions
      that reversed as quickly as 1 day in an extremely volatile fashion (e.g.
      Crude Oil, Bonds, Currencies). This has been a persistent and very unusual
      profile because it is affecting so many markets for several months at a
      time. The unusually volatile nature of markets recently is attributed to
      unresolved concerns that market participants have about inflation,
      interest rates, economic growth, and terrorism and their combined effect
      on all investable asset classes.

      In August, half of the managers in the Index had positive returns,
      representing an increase in the number of managers producing positive
      returns in recent months, with returns ranging from -7% to +8%. Overall
      Index performance was down less than 1% for the month, which represents a
      flattening out of the current drawdown momentum. Although recent months
      have experienced a dramatic lack of volatility and trading opportunities
      in most asset classes, there were strong signs of trending in most Long
      Duration Government Bond Index futures, Energy (especially Natural Gas),
      and Agricultural markets during August from which the Index profited.
      Losses offset these gains, however, in Base Metals, particularly in Nickel
      Futures, as the run up over the prior few months abruptly reversed course
      on news that warehouse inventories and Russian output is rising, which had
      the combined effect of allaying fears of continued shortages causing a
      sharp reversal downward. Other losses were incurred in Financials,
      especially in Stock Indices where prices of Equity Index Futures reversed
      their downtrend to rally with positive returns upwards of 6%. Smaller
      losses were incurred in Interest Rates where long positions in EURIBOR
      contracts and Eurodollars had minor pullbacks. Conversely, large gains
      were harvested from the Energy sector, especially from short positions in
      Natural Gas which fell from the US$6.20 level to US$5.00 during the course
      of August on news of storage injections increasing inventories to a level
      above their 5 year average combined with unseasonably cool weather
      relative to history which dampened demand for gas fired electric plant
      output. Crude Oil exposure generated small profits for the month as most
      long positions were successfully closed out at a profit prior to the
      market reversal from $US50 to $US43. Larger profits were gained from a
      uniform trend in Global Bond markets, with German, Japanese, US, and UK
      sovereign long duration debt contracts increasing in price as inflationary
      worries abated due to a retreat in Crude Oil prices combined with mixed
      economic news from the Euro-region and US. Smaller gains were also
      realized in the Wheat futures as prices continued on a downward slope in
      August.

      In September, 11 of the 14 managers had positive returns with returns
      ranging from -2% to +21%. Overall, the Index return was up nearly 4% for
      the month. With respect to markets as a whole during the last 6 months,
      the forces of accelerating interest rates, rapid commodity price
      inflation, and concern over geopolitical developments have created a
      plateau in the expected rate of change of the global economic recovery.
      This stagnation has led to much lower volatility in equities, bonds, and
      currencies and has resulted in markets that have largely traded in tightly
      bound ranges with little directional momentum or extremely choppy trends
      that detracted from Index returns during this period. In September,
      however, many markets started to show signs of momentum again and the
      trend-following strategies in the Index found and exploited trading
      opportunities in Energy, Government Bond, Metal, and Agricultural markets.
      Long positions in Energy markets provided the best trading opportunities,
      with prices in Crude Oil rising 9 straight sessions in a row to lifetime
      highs above USD $50. The causes for this rapid ascent in prices include
      fundamental global supply shortages, high demand growth, in addition to
      the effects of hurricane damage to oil rigs in the Gulf of Mexico, Russian
      Government tax reclaims from Yukos Oil Co. which are affecting deliveries
      to China, and rebel activity in Nigeria which threatens to disrupt
      supplies to western countries. Profits were also gained in long Government
      Bond positions which trended higher with pronounced momentum. U.S.
      Treasury Bond Futures, for example, rallied to a high of USD $114 in
      September due in large part to the deflationary effect of Crude Oil prices
      on the U.S. economic recovery. Gold

                                       20
<Page>

      had an equally impressive rally, which the Index participated in on the
      long side, as prices hit a low area of USD $397 in early September and
      then rallied to USD $420 on the effects of a weakened U.S. Dollar. Large
      gains were also made in long Copper Futures positions as prices drove from
      a low of USD $1.22 to almost USD $1.40 on large-scale forecasted supply
      shortages. Finally, profits were captured in short positions in Corn
      Futures which have been in a bear market spiral since early June, as
      prices dropped from USD $3.30 to recent lows around the USD $2.00 level on
      substantial gains in crop yield estimates and favorable weather forecasts.

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 investment positions. The
      majority of the Index SPC's investment 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.


THE FUND

      The Fund commenced trading on March 15, 2004 and has limited performance
      history."Standard & Poor's(R)" and "S&P Managed Futures Index" are
      trademarks of The McGraw-Hill Companies, Inc. and have been licensed for

      promoted by Standard & Poor's and Standard & Poor's makes no
      recommendation concerning the advisability of investing in the Fund.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTRODUCTION

      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 is dependent upon the expertise and
      abilities of PlusFunds in implementing the Index strategy as well as the
      Portfolio Managers who 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 is 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 and 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 make a judgment
      regarding the fair value of the assets of the Fund.

      The Fund is designed to invest in the Index SPC, a speculative commodity
      pool. The market sensitive instruments indirectly held by it are acquired
      for speculative trading purposes, and all or a substantial amount of the
      Fund's assets are indirectly subject to the risk of trading loss.

                                       21
<Page>

      Market movements result in frequent changes in the fair market value of
      the Index SPC's open positions and, consequently, in its earnings and cash
      flow. The Index SPC's market risk is influenced by a wide variety of
      factors, including the level and volatility of exchange rates, interest
      rates, equity price levels, the market value of financial instruments and
      contracts, market prices for base and precious metals, energy complexes
      and other commodities, the diversification effects among the Index SPC's
      open positions and the liquidity of the markets in which it trades.


      Frequently, the Index SPC rapidly acquires and liquidates both long and
      short positions in a wide range of different markets. Consequently, it is
      not possible to predict how a particular future market scenario will
      affect performance. The Index SPC's current trading advisors all employ
      trend-following strategies that rely on sustained movements in price.
      Erratic, choppy, sideways trading markets and sharp reversals in movements
      can materially and adversely affect the Index SPC's performance results.
      The Index SPC's past performance is not necessarily indicative of its
      future results.

QUANTITATIVE MARKET RISK

      The following quantitative disclosures regarding the Fund's exposure to
      market risk contain "forward-looking statements" within the meaning of the
      safe harbor from civil liability provided for in the Private Securities
      Litigation Reform Act of 1995 (as set forth in Section 27A of the
      Securities Act of 1993, as amended, and Section 21E of the Securities
      Exchange Act of 1934, as amended). All quantitative disclosures in this
      section are deemed to be forward-looking statements for purposes of the
      safe harbor, except for any statement of historical fact.

      The Fund's approximate risk exposure in the various market sectors traded
      by its trading advisors is quantified below in terms of value at risk.
      Value at risk is a quantitative technique used to estimate the likelihood
      that a portfolio's losses will exceed a certain amount over a given time
      frame and is alternately expressed in percentage or currency terms. The
      results of this technique should be viewed as estimations because future
      results will differ from predicted values due to changing market
      conditions that cannot be forecasted with complete accuracy.

VALUE AT RISK BY MARKET SECTORS

      The following table indicates the value at risk associated with the Index
      SPC's open positions by market category as of September 30, 2005. As of
      September 30, 2005, the Fund's Net Assets were $52,161,572. The results
      below illustrate the estimated value at risk over a 10-business day period
      at a 99% level of confidence. Value at Risk is expressed in U.S. dollars
      and VaR% is expressed as a percentage of Fund Net Assets.

QUALITATIVE MARKET RISK

TRADING RISK

      The following qualitative disclosures regarding the Fund's exposure to
      market risk contain "forward-looking statements" within the meaning of the
      safe harbor from civil liability provided for in the Private Securities
      Litigation Reform Act of 1995 (as set forth in Section 27A of the
      Securities Act of 1993, as amended, and Section 21E of the Securities
      Exchange Act of 1934, as amended). All qualitative disclosures in this
      section are deemed to be forward-looking statements for purposes of the
      safe harbor, except for any statement of historical fact and the
      descriptions of how the Fund manages its primary market risk exposures

      The Fund invests substantially all of its assets into the Index SPC. The
      following are guidelines to the primary trading risk exposures of the
      Index SPC by market sector.


      INTEREST RATES

      Interest rate risk is one of the principal market exposures of the Index
      SPC. Interest rate movements directly affect the price of interest rate
      futures positions held and indirectly the value of its stock index and
      currency positions. Interest rate movements in one country as well as
      relative interest rate movements between countries materially impact
      profitability. The primary interest rate exposure is to interest rate
      fluctuations in the United States and the other G-7 countries. However,
      the Index SPC also takes futures positions on the government debt of
      smaller nations.

      CURRENCIES

      Exchange rate risk is a significant market exposure of the Index SPC. The
      Index SPC's currency exposure is to exchange rate fluctuations, primarily
      fluctuations that disrupt the historical pricing relationships between
      different currencies and currency pairs. These fluctuations are influenced
      by interest rate changes as well as political and general economic
      conditions. The Fund trades in a large number of currencies, including
      cross-rates, which are positions between two currencies other than the
      U.S. dollar.

      ENERGY

                                       23
<Page>

      The Index SPC also has energy market exposure to gas and oil price
      movements, which often have short-term volatility swings resulting from
      political developments in the Middle East and in the long-term are subject
      to the forces of global supply and demand.

      STOCK INDICES

      The Index SPC's primary equity exposure is to equity price risk in the G-7
      countries as well as other smaller jurisdictions. The Index SPC is
      primarily exposed to the risk of adverse price trends or static markets in
      the major indices of the United States, Europe and Japan.

      METALS

      The Index SPC's metals market exposure is to fluctuations in the price of
      both precious metals, including gold and silver, as well as base metals
      including aluminum, copper, nickel and zinc. Some metals, such as gold,
      are used as surrogate stores of value, in place of hard currency, and thus
      have an associated currency or interest rate risk associated with them
      relative to their price in a specific currency. Other metals, such as
      silver, platinum, copper, and steel, have substantial industrial
      applications, and may be subject to forces affecting industrial production
      and demand.

      AGRICULTURAL

      The Index SPC may also invest in raw commodities and will thus have
      exposure to agricultural price movements, which are often directly
      affected by severe or unexpected weather conditions or by political events
      in countries that comprise significant sources of commodity supply.

      OTHER TRADING RISKS

      As a result of leverage, small changes in the price of the Portfolio
      Managers' positions may result in substantial losses to the Fund.
      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 Commodities Futures Trading Commission (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.

NON-TRADING RISK EXPOSURE

      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 monthly financial reports 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

                                       24
<Page>

      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.

      The Fund's ability to track the Index is dependent upon PlusFunds' ability
      to make the requisite allocations to all of the Portfolio Managers that
      are included in the Index. To the extent that PlusFunds is not able to
      make an allocation to a Portfolio Manager, the performance of the Fund
      will not track the performance of the Index, before fees of the Fund.

      The Fund invests substantially all of its assets in the Index SPC and is
      subject to the risks of the Index SPC as follows:

         THE INDEX SPC IS SUBJECT TO COUNTERPARTY RISKS. If the Index SPC's
         clearing broker becomes bankrupt or insolvent, or otherwise defaults on
         its 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 the clearing broker, 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 such as
         foreign exchanges or forward contract 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. There are no limitations on the amount
         of allocated assets a Portfolio Manager can trade on foreign exchanges
         or in forward contracts

         THE INDEX SPC'S POSITIONS ARE 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 Managers for the account of the Index SPC.

         SYSTEMATIC STRATEGIES DO NOT CONSIDER FUNDAMENTAL TYPES OF DATA AND DO
         NOT HAVE THE BENEFIT OF DISCRETIONARY DECISION MAKING. 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 (although certain of these strategies may
         have minor discretionary elements incorporated into their systematic
         strategy). The widespread use of technical trading systems frequently
         results in numerous Portfolio 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.
         Systematic strategies are developed on the basis of a statistical
         analysis of market prices. Consequently, any factor external to the
         market itself that dominates prices that a discretionary decision maker
         may take into account may cause major losses for a systematic strategy.
         For example, a pending political or economic event may be very likely
         to cause a major price movement, but a systematic strategy may continue
         to maintain

                                       25
<Page>

         positions indicated by its trading method that might incur major losses
         if the event proved to be adverse.

MANAGING RISK EXPOSURE

      The 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. Implicit to the
      Index SPC's construction is consideration of the quality and effectiveness
      of risk awareness and volatility monitoring on the part of the commodity
      trading advisors selected for membership in the Index. In addition,
      numerical analysis of each Portfolio Manager's historical returns with
      respect to performance in aggregate as well as in discrete periods of
      various market cycles is made as part of the due diligence process for
      consideration of membership in the Index.

      PlusFunds, the investment manager of the Index SPC and the sub-investment
      manager of the Fund, is a Delaware corporation organized on March 25,
      2002. It has been registered with the CFTC as a commodity pool operator
      since July 1, 2002 and as a commodity trading advisor since March 14, 2003
      and is a member of the National Futures Association. PlusFunds monitors
      the day-to-day performance of the Index SPC's underlying CTAs on a T+1
      basis using daily pricing information verified by independent sources.
      PlusFunds screens managers for potential anomalies, such as excessive
      leverage, abnormal changes in positions, transaction mis-pricing,
      fraudulent behavior as well as deviation from investment style. On a
      weekly basis, PlusFunds performs an analysis of portfolio exposure across
      securities, sectors, regions and asset allocation along with value at
      risk, and incremental risk analysis. PlusFunds selects the Portfolio Funds
      generally to track the Index, but there may be differences specifically if
      there is a change in Index composition.

ITEM 4.  CONTROLS AND PROCEDURES

      The General Partner of the Fund carried out an evaluation, under the
      supervision and with the participation of the General Partner's
      management, including its principal executive officer and principal
      financial officer, of the design and operation of the Fund's disclosure
      controls and procedures. Based on this evaluation, the General Partner's
      principal executive officer and principal financial officer concluded
      that, as of September 30, 2005, the Fund's disclosure controls and
      procedures were effective to provide reasonable assurance that the
      information required to be disclosed by the Fund in the reports filed or
      submitted under the Securities Exchange Act of 1934, as amended, is
      recorded, processed, summarized and reported within the time periods
      specified in the SEC's rules and forms.

      There were no changes in our internal controls over financial reporting
      during the quarter ended September 30, 2005, that have materially
      affected, or are reasonably likely to materially affect, our internal
      controls over financial reporting.

      Any control system, no matter how well designed and operated, can provide
      only reasonable (not absolute) assurance that its objectives will be met.
      Furthermore, no evaluation of controls can provide absolute assurance that
      all control issues and instances of fraud, if any, have been detected.

                           PART II- OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

On October 10, 2005, Refco Inc., ( the "Company")the parent company of RFH
announced that it had discovered through an internal review a receivable owed to
the Company by an entity controlled by Phillip R. Bennett, Chief Executive
Officer and Chairman of the Board of Directors of the Company, in the amount of
approximately $430 million. Mr. Bennett repaid the receivable in cash, including
all accrued interest, on October 10, 2005. Based upon the results of the review
to date, the Company believes that the receivable was the result of the
assumption by an entity controlled by Mr. Bennett of certain historical
obligations owed by unrelated third parties to the Company, which may have been
uncollectible. Independent Counsel and forensic auditors have been retained to
assist the Company's Audit Committee in the investigation of these matters. At
the request of the Board of Directors of the Company, Mr. Bennett has taken a
leave of absence.

On October 12, 2005, Mr. Bennett was initially charged with one count of
securities fraud. On November 10, 2005, he was indicted on eight counts of
conspiracy, fraud, and other charges by a federal grand jury. The indictment was
delivered in the United States District Court for the Southern District of New
York. Prosecutors charge in the indictment that Mr. Bennett, hid customer and
company losses from Refco auditors and investors from as early as the late
1990s. Those losses, according to the indictment, were then transferred to a
company controlled by Mr. Bennett and hidden through a series of transactions.

Mr. Bennett was removed as a Manager of RFH on October 13, 2005. Mr. Richard
Butt, President of RFH, and Annette Cazenave were installed as Managers of RFH
on that date as well as appointed to the RFH Audit Committee (the "Audit
Committee").

Since the announcement of these matters at Refco, Inc., the Audit Committee has
undertaken its own review into RFH and the Fund to ensure none of these matters
had any material impact on the results of operations of either RFH as General
Partner or the Fund. Based upon the results of that review, the Audit Committee
has no reason to believe that the actions of Mr. Bennett had any impact on the
operations or financial results of the Fund.
