ITEM 1:   BUSINESS
          --------

     (a)  General Development of Business:
          -------------------------------

          ML Principal Protection L.P. (formerly, ML Principal Protection Plus
L.P.) (the "Partnership" or the "Fund") was organized under the Delaware Revised
Uniform Limited Partnership Act on January 3, 1994 and began trading operations
on October 12, 1994.  The Partnership changed its name to ML Principal
Protection L.P. as of July 1, 1996.  The Fund is a multi-strategy, multi-market
managed futures investment employing a range of proprietary strategies
diversified across major markets of the global economy -- financials,
currencies, energy, metals and agriculture.  The Fund trades in the
international futures and forward markets under the direction of multiple
independent professional advisors (the "Trading Advisors," or the "Advisors").
The Fund's objectives are achieving, through speculative trading, long-term
capital appreciation while controlling performance volatility.

          Merrill Lynch Investment Partners Inc. (the "General Partner" or
"MLIP") acts as the general partner of the Partnership, and selects and
allocates the Fund's assets among the Advisors, each of which trades
independently of the others.  MLIP also determines what percentage of the Fund's
assets to allocate to trading and what percentage to hold in reserve.  Merrill
Lynch Futures Inc. (the "Commodity Broker" or "MLF") is the Partnership's
commodity broker.  Merrill Lynch Asset Management, L.P. ("MLAM") provides cash
management services to the Partnership, pursuant to guidelines established by
MLIP for which MLAM assumes no responsibility, investing Fund assets in
securities issued by the U.S. Government and its agencies ("Government
Securities").  The General Partner is a wholly-owned subsidiary of Merrill Lynch
Group Inc., which in turn is a wholly-owned subsidiary of Merrill Lynch & Co.,
Inc. ("ML&Co.").  The Commodity Broker is an indirect wholly-owned subsidiary of
ML&Co.  (ML&Co. and its affiliates are herein sometimes referred to as "Merrill
Lynch.")

          The Partnership does not trade directly but rather through a
subsidiary limited partnership, ML Principal Protection Trading L.P. (formerly,
ML Principal Protection Plus Trading, L.P.) (the "Trading Partnership"), of
which the General Partner is the general partner and the Partnership the sole
limited partner.  See Item 1(c), "Narrative Description of Business -- Two-Tier
Structure of the Fund."

          The Fund offers its units of limited partnership interest ("Units")
and receives and processes subscriptions, on a continuous basis, throughout each
calendar quarter at $100 per Unit.  Investors whose subscriptions are accepted
at any time during a calender quarter are admitted to the Fund as Limited
Partners as of the beginning of the immediately following quarter.  Investors'
customer securities accounts are debited in the amount of their subscriptions on
settlement dates throughout each quarter shortly after their subscriptions are
accepted by MLIP. Subscription proceeds received during a quarter are held in
escrow pending investment in Units as of the beginning of the following quarter.
All interest earned on subscriptions while held in escrow is paid to the
investors on or about the date that Units are issued to them or their
subscription is rejected.

          The Units sold at the beginning of each calendar quarter (and also May
1, 1997) are sold in separate series, each of which has its own Net Asset Value.
All series trade pursuant to the same Advisor combination, but because they
begin trading at  different times they have different Net Asset Values and may
have different percentages of their capital invested in the Trading Partnership
and allocated to the Trading Advisors for management.

          Only the assets attributable to each series of Units and allocated to
the Trading Partnership are allocated to the Trading Advisors for management.
All outstanding series of Units currently being issued initially allocate
approximately 75% of their total capital to the Trading Partnership, holding the
rest in reserve at the Partnership level.

          MLIP may from time to time direct certain individual Advisors to
manage their Fund accounts as if they were managing up to 50% more equity than
the actual capital allocated to them.  This additional leverage is subject to
the condition that the Fund as a whole will not trade as if it had in excess of
20% more equity than actual capital.

                                      -1-
<PAGE>

          When the Fund began trading in October 1994, it had an initial
capitalization of $32,000,000. Through December 31, 1997, a total of an
additional $110,143,741 had been invested in the Units at subsequent quarter-end
closings and also a May 1, 1997 closing (the last sale of the Units occurred as
of October 15, 1997). Through December 31, 1997, Units with an aggregate Net
Asset Value of $49,025,567 have been redeemed (including December 31, 1997
redemptions which were not actually paid out until January 1998), the
Partnership's capitalization was $101,226,685, and the Fund had a total of 3,783
Limited Partners.

          Through December 31, 1997, the net gain in the Net Asset Value per
Series A Unit (the initial series of Units) was 13.73%, the highest month-end
Net Asset Value of a Series A Unit was $116.48 (after reducing such Net Asset
Value by distributions of $15.50 per Series A Unit ), as of July 1997 , and the
lowest $101.04, as of October 1994.

          The outstanding Series of Units are entitled to fixed-rate annual
distributions (which cannot be reduced prior to the first Principal Assurance
Date, as defined below, for such Series) and may also receive certain
discretionary distributions.  MLIP does not presently intend to make any
distributions on any series of Units sold after July 16, 1996.

          The Fund is a "principal protected" commodity pool.  ML&Co. provides
the guarantee described below ML&Co.'s under 1(c), "Narrative Description of
Business -- ML&Co.'s 'Principal Protection' Undertaking to the Fund"  that all
Units of any given series will have a Net Asset Value -- after payment of all
fixed-rate annual as well as discretionary distributions on such Units, in the
case of Units sold on or prior to July 16, 1996 -- of at least their initial
$100 subscription price as of a specified date after their issuance (the
"Principal Assurance Date" for such series, seven years after issuance for all
outstanding Series of Units, anticipated to be generally five years after
issuance for Series sold after July 16, 1996).  This guarantee does not prevent
substantial losses, but rather serves only as a form of "stop loss," limiting
the maximum loss which investors who retain their Units until such Units'
Principal Assurance Date can incur.  In order to protect ML&Co. from any
liability under its guarantee, MLIP imposes substantial opportunity costs on the
Partnership by deleveraging its trading, retaining a substantial portion of the
Fund's assets in the Partnership rather than investing such assets in the
Trading Partnership for allocation to trading.  At such time, if any, as the Net
Asset Value per Unit of a Series declined to 110% or less of the present value
of $100, plus any fixed-rate annual distributions due on such Series, discounted
back from the Principal Assurance Date, MLIP would terminate trading with
respect to such Series altogether in order to ensure that ML&Co. incurred no
financial obligation to the Fund under ML&Co.'s guarantee of the minimum Net
Asset Value per Unit of such Series.

          In the case of Units sold after July 16, 1996, the potential
opportunity costs of the Fund's "principal protection" are significantly
increased due to the fact that in the event that MLIP deleverages any particular
series of Units, it must deleverage all series to the same degree.  A series
could be deleveraged as a result of losses which accrued subsequent to such
series having recognized profits more than sufficient to offset such losses, but
which were earned before a more recent series was issued and, consequently, were
not available to offset the same losses incurred by such series.  Conversely,
losses incurred before a particular series is issued could indirectly cause a
further deleveraging of such series' trading due to the effect of such losses on
the leverage which MLIP believes it is appropriate to use for an earlier-issued
series.

     (b)  Financial Information about Industry Segments:
          ---------------------------------------------

          The Partnership's business constitutes only one segment for financial
reporting purposes, i.e., a speculative "commodity pool."

     (c)  Narrative Description of Business:
          ---------------------------------

          GENERAL

          The Fund trades in the international futures, options on futures and
forward markets, with the objectives of achieving long-term capital appreciation
while controlling performance volatility.

                                      -2-
<PAGE>

          One of the objectives of the Fund is to provide diversification for a
limited portion of the risk segment of the Limited Partners' portfolios.
Commodity pool performance has historically often demonstrated a low degree of
performance correlation with traditional stock and bond holdings.  Since it
began trading, the Fund's returns have, in fact, frequently been significantly
non-correlated (not, however, negatively correlated) with the United States
stock and bond markets.

          Due to certain concerns expressed by the Securities and Exchange
Commission (the "SEC") regarding whether the different series of Units issued by
the Partnership were significantly similar to each other for the Partnership to
be considered to be engaged in a "continuous offering" of the same class of
security, i.e., the Units (which the Partnership must be in order not to be able
to offer the Units on an ongoing open-end basis), MLIP changed the terms of all
series to be issued after July 16, 1996 to provide that: (i) no distributions
are intended to be made on any such series; (ii) any discretionary trading
leverage adjustments would have to  be made so that after any such adjustments
all series were  trading at the same degree of leverage (i.e., with the same
percentage of their total capital invested in the Trading Partnership and
allocated to the Advisors for management); and (iii) all series would have the
same five year "Time Horizon" between their respective issuance dates and their
respective Principal Assurance Dates. The series issued on and prior to July 16,
1996 have seven-year Time Horizons, are entitled to fixed rate as well as
discretionary distributions and contemplate MLIP adjusting the leverage of each
series in MLIP's discretion on an individual series-by-series basis.

          ML&CO.'S "PRINCIPAL PROTECTION" UNDERTAKING TO THE FUND

          ML&Co. has agreed to contribute sufficient capital to the Partnership
so that it will have adequate funds, after adjusting for all liabilities to
third parties, that the Net Asset Value per Unit of each Series will be no less
than $100 as of the Principal Assurance Date for such Series (after the payment
of all distributions, if any, on Units of such Series).  This guarantee, which
is effective with respect to any given Series as of the Principal Assurance Date
for such Series, is a guarantee only of a return of an investor's initial
investment (plus distributions, if any), and not on a present value basis, not a
guarantee of profit.

          OPERATION OF A SERIES AFTER ITS PRINCIPAL ASSURANCE DATE

          MLIP may determine to dissolve a Series as of its Principal Assurance
Date, to extend the ML&Co. guarantee for a certain period of time (resetting the
minimum Net Asset Value per Unit of such Series guaranteed by ML&Co.) or to
continue to operate such Series without a "principal protection" feature.

          TWO-TIER STRUCTURE OF THE FUND

          The Fund does not trade in the futures and forward markets directly,
but rather through the Trading Partnership, of which the Fund is the sole
limited, and MLIP the sole general partner.  The Fund's liability for any
trading losses is limited to the Fund's investment in the Trading Partnership.

          USE OF PROCEEDS AND CASH MANAGEMENT INCOME

          Subscription Proceeds.  MLIP pays from its own funds the selling
          ---------------------
commissions relating to the sale of the Units.  Accordingly, 100% of the
proceeds of Unit sales are received in cash by the Partnership and available for
use in its speculative trading.  In such trading, the Partnership's assets are
used as security for and to pay the Partnership's trading losses as well as any
expenses and redemptions.  The primary use of the proceeds of the sale of the
Units is to permit the Advisors to trade on a speculative basis in a wide range
of different futures, forwards and options on futures markets on  behalf of the
Trading Partnership.  While being used for this purpose, the Partnership's
assets are also generally available for cash management and to earn interest, as
more fully described below under "-- Available Assets."

          Market Sectors.  The Partnership trades in a diversified group of
          --------------
markets under the direction of multiple independent Advisors.  These Advisors
can, and do, from time to time materially alter the allocation of their overall
trading commitments among different market sectors.   Except in the case of
certain trading programs which are purposefully limited in the markets which
they trade, there is essentially no restriction on the commodity interests which
may be traded by any Advisor or the rapidity with which an Advisor may alter its
market sector allocations.

                                      -3-
<PAGE>

          The Fund's financial statements contain information relating to the
market sectors traded by the Fund. There can, however, be no assurance as to
which markets may be included in the Fund's portfolio or as to in which market
sectors the Fund's trading may be concentrated at any one time or over time.

          Market Types.  The Partnership trades on a variety of United States
          ------------
and foreign futures exchanges. Applicable exchange rules differ significantly
among different countries and exchanges.  Substantially all of the Fund's off-
exchange trading takes places in the highly liquid, institutionally-based
currency forward markets.  The forward markets are generally unregulated, and in
its forward trading the Fund does not deposit margin with respect to its
positions.  The Partnership's forward currency trading is executed exclusively
through the Foreign Exchange Service Desk (the "F/X Desk") operated by MLIP and
certain of its affiliates, with MLF as the "back-to-back" intermediary to the
ultimate counterparties, which include Merrill Lynch International Bank ("MLIB")
with which the Advisors trade on behalf of the Fund.

          As in the case of its market sector allocations, the Fund's
commitments to different types of markets -- U.S. and non-U.S., regulated and
unregulated -- differ substantially from time to time as well as over time.  The
Fund has no policy restricting its relative commitments to any of these
different types of markets.

          The Fund's financial statements contain information relating to the
types of markets traded by the Fund.  There can, however, be no assurance as to
in which markets the Fund may trade or the Fund's trading may be concentrated at
any one time or over time.

          Custody of Assets.  All of the Fund's assets -- other than the assets
          -----------------
managed by MLAM and held in a custodial account as described below under "--The
Fund's U.S. Dollar Available Assets Managed by MLAM" -- are currently held in
customer accounts at Merrill Lynch.

          Available Assets.  The Fund earns interest, as described below, on its
          ----------------
"Available Assets,"  which can be generally described as the cash actually held
by the Fund or invested in short-term Treasury bills.  Available Assets are held
primarily in U.S. dollars or in U.S. dollar denominated Government Securities,
and to a lesser extent in foreign currencies, and are comprised of the
following:  (a) the Fund's cash balances managed by MLAM or held in the offset
accounts (as described below) -- which include "open trade equity" (unrealized
gain and loss on open positions) on United States futures contracts, which is
paid into or out of the Fund's account on a daily basis; and (b) the Fund's cash
balance in foreign currencies derived from its trading in non-U.S. dollar
denominated futures and options contracts,  which includes open trade equity on
those exchanges which settle gains and losses on open positions in such
contracts prior to closing out such positions.  Available Assets do not include,
and the Fund does not earn interest on, the Fund's gains or losses on its open
forward, commodity option and certain foreign futures positions since such gains
and losses are not collected or paid until such positions are closed out.

          The Partnership's Available Assets may be greater than, less than or
equal to the Fund's Net Asset Value (on which the redemption value of the Units
is based) primarily because Net Asset Value reflects all gains and losses on
open positions as well as accrued but unpaid expenses.

          The interest income arrangements for the Partnership's U.S. dollar
Available Assets differ from those applicable to its non-U.S. dollar Available
Assets.  Interest income, once accrued by the Fund, is subject to the risk of
trading losses.

          The Fund's U.S. Dollar Available Assets Managed by MLAM.
          -------------------------------------------------------
Approximately 80% of the Fund's U.S. dollar Available Assets are managed
directly by MLAM, pursuant to guidelines established by MLIP for which MLAM
assumes no responsibility, in the Government Securities markets.  MLIP's
objective in retaining MLAM to provide cash management services to the Fund is
to enhance the return earned on the Fund's U.S. dollar Available Assets  managed
by MLAM to slightly above the 91-day Treasury bill rate, while maintaining
minimal (but by no means eliminating) market risk in the Fund's cash management
operations.

          The Government Securities acquired by MLAM on behalf of the Fund are
maintained in a custodial account at a Merrill Lynch affiliate and are
specifically traceable to the Fund.  All income earned on such Government
Securities inures to the benefit of the Fund.

                                      -4-
<PAGE>

          MLF pays all fees due to MLAM in respect of its management of a
portion of the Fund's U.S. dollar Available Assets, at no additional cost to the
Fund.

          MLAM does business as Merrill Lynch Asset Management.  MLAM is a
limited partnership. ML&Co. is its limited partner, and Princeton Services,
Inc., a wholly-owned subsidiary of ML&Co., is the general partner.

          Interest Earned on the Fund's U.S. Dollar Available Assets Not Managed
          ----------------------------------------------------------------------
by MLAM.  The following description relates to the approximately 20% of the
-------
Fund's U.S. dollar Available Assets not managed by MLAM.

          The Fund's U.S. dollar Available Assets not managed by MLAM are held
in cash in offset accounts and in short-term Treasury bills purchased from
dealers unaffiliated with Merrill Lynch.  Offset accounts are non-interest
bearing demand deposit accounts maintained with banks unaffiliated with Merrill
Lynch.  An integral feature of the offset arrangements is that the participating
banks specifically acknowledge that the offset accounts are MLF customer
accounts, not subject to any Merrill Lynch liability.

          MLF credits the Partnership, as of the end of each month, with
interest at the effective daily 91-day Treasury bill rate on the average daily
U.S. dollar Available Assets held in the offset accounts during such month.  The
Fund receives all the interest paid on the short-term Treasury bills in which it
invests.

          The use of the offset account arrangements for the Partnership's U.S.
dollar Available Assets not managed by MLAM may be discontinued by Merrill Lynch
whether or not Merrill Lynch otherwise continues to maintain its offset
arrangements.  The offset arrangements are dependent on the banks' continued
willingness to make overnight credits available to Merrill Lynch, which, in
turn, is dependent on the credit standing of ML&Co.  If Merrill Lynch were to
determine that the offset arrangements had ceased to be practicable (either
because ML&Co. credit lines at participating banks were exhausted or for any
other reason), Merrill Lynch would thereafter attempt to invest all of the
Fund's U.S. dollar Available Assets not managed by MLAM to the maximum
practicable extent in short-term United States Treasury bills.  All interest
earned on the U.S. dollar Available Assets so invested would be paid to the
Fund, but MLIP would expect the amount of such interest to be less than that
available to the Fund under the offset account arrangements.  The remaining U.S.
dollar Available Assets of the Fund not managed by MLAM would be kept in cash to
meet variation margin payments and pay expenses, but would not earn interest for
the Fund.

          The banks at which the offset accounts are maintained make available
to Merrill Lynch interest-free overnight credits, loans or overdrafts in the
amount of the Fund's U.S. dollar Available Assets held in the offset accounts,
charging Merrill Lynch a small fee for this service.  The economic benefits
derived by Merrill Lynch -- net of the interest credits paid to the Fund and the
fee paid to the offset banks -- from the offset accounts have not exceeded  3/4
of 1% per annum of the Fund's average daily U.S. dollar Available Assets not
managed by MLAM and held in the offset accounts.  These revenues to Merrill
Lynch are in addition to the Brokerage Commissions and Administrative Fees paid
by the Fund to MLF and MLIP, respectively.

          Interest Paid by Merrill Lynch on the Fund's Non-U.S. Dollar Available
          ----------------------------------------------------------------------
Assets.  Under the single currency margining system implemented for the
-------
Partnership, the Partnership itself does not deposit foreign currencies to
margin trading in non-U.S. dollar denominated futures contracts and options. MLF
provides the necessary margin, permitting the Fund to retain the monies which
would otherwise be required for such margin as part of the Partnership's U.S.
dollar Available Assets.  The Partnership does not earn interest on foreign
margin deposits provided by MLF.  The Partnership does, however, earn interest
on its non-U.S. dollar Available Assets.  Specifically, the Fund is credited by
Merrill Lynch with interest at the local short-term rate on realized and
unrealized gains on non-U.S. dollar denominated positions for such gains
actually held in cash by the Fund (MLAM does not manage any of the Fund's non-
U.S. dollar Available Assets.).  Merrill Lynch charges the Fund Merrill Lynch's
cost of financing realized and unrealized losses on such positions.

          In order to avoid the expense of daily currency conversions, the
Partnership holds foreign currency gains and finances foreign currency losses on
an interim basis until converted into U.S. dollars and either paid into or out
of the Partnership's U.S. dollar Available Assets.  Foreign currency gains or
losses on open positions are not converted into U.S. dollars until the positions
are closed.  Assets of the Partnership while held in foreign currencies are
subject to exchange rate risk.

                              ____________________

          The General Partner has determined that there may have been a
miscalculation in the interest credited to the Fund for a period prior to
November 1996.  Accordingly, Merrill Lynch has credited the Fund's investors.
For current Merrill Lynch clients, this credit, which includes compounded
interests, appears on the December 1997 account statements.  The total amount of
the adjustment is approximately $54,000.

*  Only approximately 60% of the Fund's average month-end Net Assets were
   allocated to trading during the periods presented.  Series of Units issued
   subsequent to July 16, 1996 (no such Units have been issued as of the date of
   this Report) will commence trading with 75% of their assets allocated to

          The foregoing table does not reflect the bid-ask spreads paid by the
Fund on its forward trading, or the benefits which may be derived by Merrill
Lynch from the deposit of certain of the Fund's U.S. dollar available assets in
offset accounts.  See Item 1(c), "Narrative Description of Business -- Use of
Proceeds and Cash Management Income."

          The Fund's average month-end Net Assets during 1995, 1996 and 1997
equaled $55,827,125, $82,789,767 and $85,646,152 respectively.

          During 1995, 1996 and 1997,  the Fund earned $3,415,670, $4,545,186
and $4,873,872 in interest income, or approximately 6.12%, 5.49% and 5.69% of
the Fund's average month-end Net Assets.

          Effective January 1, 1997, MLIP reduced the Fund's annual Brokerage
Commissions from 9.25% to 8.75% of trading assets (i.e., assets committed to
trading).

                                            committed to trading.  The Fund initially commits
                                            8.75% of the capital attributable to each series of Units
                                            issued after July 16, 1996 to trading.

                                            $116, and $116 respectively.  The round-turn rate for
                                            1995 and 1996 reflect Brokerage Commissions at the
                                            rate of 9.25% per annum.

                                            As of January 1, 1997, the 9.25% per annum
                                            Brokerage Commissions were reduced to 8.75% per
                                            annum (0.7291 of 1% of the Fund's month-end assets).

                           ------------------------

          REGULATION

          The General Partner, the Trading Advisors and the Commodity Broker are
each subject to regulation by the Commodity Futures Trading Commission (the
"CFTC") and the National Futures Association.  Other than in respect of its
periodic reporting requirements under the Securities Exchange Act of 1934, and
the registration of the Units for continuous public distribution under the
Securities Act of 1933, the Partnership itself is generally not subject to
regulation by the Securities and Exchange Commission.  However, MLIP itself is
registered as an "investment adviser" under the Investment Advisers Act of 1940.

          (i) through (xii) -- not applicable.

          (xiii)  The Partnership has no employees.

<PAGE>

     (d)  Financial Information about Foreign and Domestic Operations and Export
          ----------------------------------------------------------------------
Sales:
-----

          The Partnership and the Trading Partnership do not engage in material
operations in foreign countries, nor is a material portion of the Partnership's
revenues derived from customers in foreign countries.  The Trading Partnership
does, however, trade, from the United States, on a number of foreign commodity
exchanges.

ITEM 2:   PROPERTIES
          ----------

     Neither the Partnership nor the Trading Partnership use any physical
properties in the conduct of its business.

     The Partnership's and the Trading Partnership's only place of business is
the place of business of the General Partner (see Item 10 herein).  The General
Partner performs all administrative services for the Partnership and the Trading
Partnership from the General Partner's offices.

ITEM 3:   LEGAL PROCEEDINGS
          -----------------

          ML&Co. -- the sole stockholder of Merrill Lynch Group, Inc. (which is
the sole stockholder of MLIP) -- as well as certain of its subsidiaries and
affiliates have been named as defendants in civil actions, arbitration
proceedings and claims arising out of their respective business activities.
Although the ultimate outcome of these actions cannot be ascertained at this
time and the results of legal proceedings cannot be predicted with certainty, it
is the opinion of management that the result of these matters will not be
materially adverse to the business operations of financial condition of MLIP or
the Fund.

          MLIP itself has never been the subject of any material litigation.

          On June 24, 1997, the CFTC accepted an Offer of Settlement from MLF
and others, in a matter captioned "In the Matter of Mitsubishi Corporation and
Merrill Lynch Futures Inc., et al.," CFTC Docket No. 97-10, pursuant to which
MLF, without admitting or denying the allegations against it, consented to a
finding by the Commission that MLF had violated Section 4c(a)(A) of the
Commodity Exchange Act, relating to wash sales (the CFTC alleged that the
customer entered nearly simultaneous orders without the intent to engage in a
bona fide trading transaction), and CFTC Regulation 1.37(a), relating to
recordkeeping requirements.  MLF agreed to cease and desist from violating
Section 4c(a)(A) of the Act and Regulation 1.37(a), and to pay a civil monetary
penalty of $175,000.

ITEM 4:   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
          ---------------------------------------------------

     The Partnership has never submitted any matters to a vote of its Limited
Partners.


                                    PART II

ITEM 5:   MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS
          ---------------------------------------------------------------------

     (a)  Market Information:
          ------------------

          There is no established public trading market for the Units, nor will
one develop.  Rather, Limited Partners may purchase or redeem Units as of the
end of each month at Net Asset Value, subject to certain early redemption
charges. Units redeemed prior to the Principal Assurance Date are not entitled
to any benefits under the Merrill Lynch & Co., Inc. guarantee.

     (b)  Holders:
          -------

          As of December 31, 1997, there were 3,793 holders of Units, including
the General Partner.

<PAGE>

     (c)  Dividends:
          ---------

          For series issued on or prior to July  16, 1996, the Partnership makes
annual fixed-rate distributions, payable irrespective of profitability, of
between $2 and $5 per Unit (depending upon the series).  The General Partner may
also make discretionary distributions of up to 50% of any Distributable New
Appreciation, as defined, recognized as of each twelve-month anniversary of the
issuance of each series of Units, subject to an annual limit of 4% of the Net
Asset Value per Unit of each series as of the beginning of the preceding twelve-
month period.  The first such distribution with respect to the Series A Units
took place on October 1, 1995.  At such time Series A Unitholders received a
fixed-rate distribution equal to $3.50 per Unit and a discretionary distribution
equal to $2.50 per Unit (for a total distribution of $6.00 per Unit). Series A
Unitholders received another distribution of $6.00 per Unit on October 1, 1996.
Series A Unitholders received a fixed-rate distribution of $3.50 on October 1,
1997.  The first distribution with respect to Series B Units took place on
January 1, 1996.  At such distribution, Series B Unitholders also received a
fixed-rate distribution equal to $3.50 per Unit and a discretionary distribution
equal to $2.50 per Unit (for a total distribution of $6.00 per Unit).  On
January 1, 1997, Series B received a fixed-rate distribution of $3.50 and a
discretionary distribution of $3.00.  The first of such distributions for Series
C, D and E of a fixed rate distribution of $3.50 per Unit took place on April 1,
1996, July 1, 1996 and October 1, 1996, respectively.  On April 1, 1997, Series
C received a fixed rate dividend of $3.50 and a discretionary dividend of $4.00.
On July 1, 1997, Series D received a fixed-rate dividend of $3.50 and a

  Rates of Return are presented on a composite, not a series-by-series, basis.

                           _________________________

          THE UNITS ISSUED AFTER JULY 16, 1996 COMMENCE TRADING WITH 75% OF
THEIR ASSETS ALLOCATED TO TRADING. ALL SERIES OF UNITS ISSUED TO DATE HAVE
TRADED AT ONLY APPROXIMATELY 60% LEVERAGE.  INCREASING TRADING LEVERAGE SHOULD
INCREASE MONTHLY RATES OF RETURN (BOTH POSITIVE AND NEGATIVE), DRAWDOWNS, PROFIT
POTENTIAL, RISK AND VOLATILITY.

                           _________________________

          (1)  Pursuant to applicable CFTC regulations, a "Multi-Advisor" fund
is defined as one that allocates no more than 25% of its trading assets to any
single manager.  The Fund does not currently allocate more than 25% of its
trading assets to any single Advisor but may do so in the future; consequently,
it is referred to as a"Multi-Advisor; Selected Advisor" fund. Certain funds,
including funds sponsored by MLIP, are structured so as to guarantee to
investors that their investment will be worth no less than a specified amount
(typically, the initial purchase price) as of a date certain after the date of
investment.  The CFTC refers to such funds as "principal protected."  The ML&Co.
Guarantee and MLIP related deleveraging of the Fund's trading provides the
"principal protection" feature of the Fund.

          (2)  Worst Monthly Drawdown  represents the largest negative Monthly
Rate of Return experienced by the Fund; a drawdown is measured on the basis of
month-end Net Asset Value only, and does not reflect intra-month figures.

          (3)  Worst Peak-to-Valley Drawdown  represents the greatest percentage
decline from a month-end cumulative Monthly Rate of Return without such
cumulative Monthly Rate of Return being equaled or exceeded as of a subsequent
month-end.  For example, if the Monthly Rate of Return was (1)% in each of
January and February, 1% in March and (2)% in April, the Peak-to-Valley Drawdown
would still be continuing at the end of April in the amount of approximately
(3)%, whereas if the Monthly Rate of Return had been approximately 3% in March,
the Peak-to-Valley Drawdown would have ended as of the end of February at
approximately the (2)% level.

          (4)  Monthly Rate of Return is the net performance of the Fund during
the month of determination (including interest income and after all expenses
accrued or paid) divided by the total equity of the Fund as of the beginning of
such month.  The composite returns of the Fund reflect the results of the Fund
as a whole, not the performance of any single series of Units (however, the
composite returns closely match during the same period the performance of all
series then outstanding).  Although the series begin trading at different times
and, accordingly, have materially different cumulative returns, as all series
participate in the same trading account and at approximately the same degree of
leverage, the only significant difference between the performance of different
series during a given month is typically the different amount of Profit Shares
paid. In no month has any series had a rate of return 10% higher or lower than
any other series.

ITEM 7:   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          ---------------------------------------------------------------
RESULTS OF OPERATIONS
---------------------

     THE TWO-TIER STRUCTURE OF THE FUND

     The Fund does not trade directly through opening managed accounts with the
Advisors, but rather through investing in the Trading Partnership.  The Trading
Partnership, in turn, allocates substantially all of its capital to the
Advisors, and the different series of Units share pro rata in the overall
profits and losses of the Trading Partnership based on their respective
investments in it.  No series of Units can lose more in its trading than the
amount which such series has invested in the Trading Partnership.

     Although different series of Units invest different percentages of their
overall capital in the Trading Partnership, all assets so invested are 100%
allocated to trading.  All trading losses are shared pro rata among the
different series based on their respective investments in the Trading
Partnership.

     The use of the Trading Partnership by the Fund has no effect on the
leverage at which the different series of Units trade. The Fund trades through
investing in the Trading Partnership rather than directly, solely in order to
eliminate the highly unlikely risk that one series of Units might be subject to
paying trading debts attributable to another.  This risk arises because it is
theoretically possible that catastrophic losses could deplete all the assets of
a particular series allocated to the Advisors for management.  Any remaining
losses  would remain a debt of the Fund to which all other series' capital would
be subject.  The Fund/Trading Partnership structure eliminates the risk of such
inter-series liability.  The CFTC would not permit the Fund to continue the
offering of the Units unless such inter-series liability were eliminated.

     For example, assume that each of Series I and Series II Units had $10
million in capital, and Series I allocated $9.5 million (95% leverage) and
Series II $8.5 million (85% leverage) to the Trading Partnership.  If losses
bankrupted the Trading Partnership, each Series' trading account would share pro
rata in such losses.  The Series I Units would create a larger deficit balance
because of the higher degree of leverage at which that Series traded.  However,
there would be no risk that, for example, a $3 million deficit balance allocable
to Series I trading account would be subject to being repaid from any of the
$1.5 million withheld from trading by the Series II Units (or from any of the
$0.5 million withheld from trading by the Series I Units, for that matter),
because the Fund itself is not liable for the debts of its subsidiary Trading
Partnership.  Any deficit balance incurred by a bankrupt Trading Partnership
would become an uncollectible debt due to MLF.  MLF accepts such deficit balance
risk each time it accepts a limited liability entity such as the Trading
Partnership as a client.

     There is no benefit (or detriment) to investors from the two-tier
Fund/Trading Partnership structure other than permitting the Fund to issue the
series of Units at different times, which series, may, over time, trade with
different percentages of their capital allocated to trading.

     OPERATIONAL OVERVIEW; ADVISOR SELECTIONS

     The Fund's results of operations depend on MLIP's ability to select
Advisors and the Advisors' ability to trade profitably. MLIP's selection
procedures and trading leveraging analysis, as well as the Advisors' trading
methods, are confidential, so that  substantially the only available information
relevant to the Fund's results of operations is its actual performance record to
date.

However, because of the speculative nature of its trading, the Fund's past
performance is not necessarily indicative of its future results.

     MLIP's decision to terminate or reallocate assets among Trading Advisors is
based on a combination of numerous factors. Advisors are, in general, terminated
primarily for unsatisfactory performance, but other factors -- for example, a
change in MLIP's or an Advisor's market outlook, apparent deviation from
announced risk control policies, excessive turnover of positions, changes in
principals, commitment of resources to other business activities, etc. -- may
also have a role in the termination or reallocation decision.  The market
judgment and experience of MLIP's principals is an important factor in its
allocation decisions.

     MLIP has no timetable or schedule for making Advisor changes or
reallocations, and generally makes a medium- to long-term commitment to all
Advisors selected.  There can be no assurance as to the frequency or number of
the Advisor changes that may take place in the future, or as to how long any of
the current Advisors will continue to manage assets for the Partnership.

     RESULTS OF OPERATIONS

       General.  MLIP believes that multi-advisor futures funds should be
       -------
regarded as medium- to long-term (i.e., three to five year) investments, but it
is difficult to identify trends in the Fund's operations and virtually
impossible to make any predictions regarding future results based on the results
to date.  An investment in the Fund may be less successful over a longer than a
shorter period.

     Markets with sustained price trends tend to be more favorable to managed
futures investments than whipsaw, choppy markets, but (i) this is not always the
case, (ii) it is impossible to predict when price trends will occur and (iii)
different Advisors are affected differently by trending markets as well as by
particular types of trends.

     MLIP attempts to control credit risk in the Fund's futures, forward and
options trading (the Fund does not trade derivatives other than futures and
forward contracts and options thereon) by trading only through MLF. MLF acts
solely as a broker or counterparty to the Fund's trades; it does not advise with
respect to, or direct, any such trading.

     MLIP attempts to control the market risk inherent in the Fund's trading by
MLIP multi-advisor structuring and Trading Advisor selection.  MLIP reviews the
positions acquired by the Advisors on a daily basis in an effort to determine
whether the overall positions of the Fund may have become what MLIP analyzes as
being excessively concentrated in a limited number of markets or under the
direction of generally similar strategies -- in which case MLIP may, as of the
next month-end or quarter-end, adjust the Fund's Advisor combination and/or
allocations so as to attempt to reduce the risk of such over-concentration
occurring in the future.  MLIP also adjusts the percentage of each series'
capital allocated to trading, with the principal objective of protecting ML&Co.
from any liability under its guarantee of a $100 minimum Net Asset Value per
Unit as of the Principal Assurance Date for each of the respective series of
Units.  The market risk to the Fund is limited by the combination of its
"principal protection" feature and its multi-advisor strategy.

     Prior to July 16, 1996, all series of Units initially allocated
approximately 60% of their assets to trading.  All series of Units sold after
July 16, 1996 initially allocate 75% of their assets to trading.  MLIP's
determination as to how much of a series' capital to allocate to trading from
time to time -- again, a determination primarily dictated by MLIP's objective of
ensuring that ML&Co. is never required to make any payments under its guarantee
that the Net Asset Value per Unit of each series will be at least $100 as of
such series' Principal Assurance Date-- has a material impact on the performance
of such series.

     In the case of Units issued subsequent to July 16, 1996, MLIP's ability to
adjust the leverage at which these series trade is restricted by the regulatory
requirement that if MLIP adjusts the leverage of any one such series, it must
adjust the leverage of all such series so that all are trading with the same
percentage of their total capital allocated to trading.

     MLIP may consider making distributions on the Units offered subsequent to
July 16, 1996 under certain circumstances (for example, if substantial profits
are recognized); however, MLIP does not presently intend to do so.  MLIP has,
however, undertaken to make certain distributions on all Units issued on or
prior to July 16, 1996.

     The performance of the different series of Units differs somewhat over the
same period, primarily, because as the various series begin trading at different
times, they pay different Profit Shares (although at the same base rates),
during the same periods.

     PERFORMANCE SUMMARY

     1995

     In 1995, prevailing price trends in several key markets enabled the
Advisors to trade profitably for the Fund.  Although trading in many of the
traditional commodity markets may have been lackluster, the currency and
financial markets offered exceptional trading conditions.  After months
characterized by very difficult trading environments, solid price trends across
many markets (including U.S. Treasury and non-dollar bond markets) began to
emerge during the first quarter of 1995.  In the second quarter of 1995, market
volatility once again began to affect trading, as many previously strong price
trends began to weaken and, in some cases, reverse.  The U.S. dollar hit new
lows versus the Japanese yen and Deutschemark before rebounding sharply.  In
addition, there were strong indications that the U.S. economy was slowing which,
when coupled with a failure of the German Central Bank to lower interest rates,
stalled a rally in the German bond market.  During the

                                      -16-
<PAGE>

third quarter there was a correction in U.S. bond prices after several months of
a strong uptrend. Despite exposure to the global interest-rate markets, the
Fund's long positions in U.S. Treasury bonds had a negative impact on
performance. Throughout August and into September, the U.S. dollar rallied
sharply against the Japanese yen and the Deutschemark as a result of the
coordinated intervention by major central banks and widespread recognition of
the growing banking crisis in Japan. Despite continued price volatility during
the final quarter of 1995, the Trading Advisors were able to identify several
trends in key markets. U.S. Treasury bond prices continued their strong move
upward throughout November, due both to weak economic data and optimism on
federal budget talks. As the year ended, the yield on the 30-year Treasury bond
was pushed to its lowest level in more than two years.

     1996

     1996 began with the East Coast blizzard, continuing difficulties in the
U.S. federal budget talks and an economic slowdown having a negative impact on
many markets.  The Fund was profitable in January due to the strong profits in
currency trading as the U.S. dollar reached a 23-month high against the Japanese
yen.  In February, however, the Fund incurred its worst monthly loss due to the
sudden reversals in several strong price trends and considerable volatility in
the currency and financial markets.  During March, large profits were taken in
the crude oil and gasoline markets as strong demand continued and talks between
the United Nations and Iraq were suspended.  This trend continued into the
second quarter, during which strong gains were also recognized in the
agricultural markets as a combination of drought and excessive rain drove wheat
and grain prices to historic highs.  In  the late summer and early fall months,
the Fund continued to trade profitably as trending prices in a number of key
markets favorably impacted the Fund's performance.  In September heating oil hit
a five-year high on soaring prices in Europe, and the Fund was also able to
capitalize on downward trends in the metals markets.  Strong trends in the
currency and global bond markets produced significant gains in October and
November, but the year ended with declining performance as December witnessed
the reversal of several strong upward trends and increased volatility in key
markets.

     1997

     In currency markets, the U.S. dollar rallied and started 1997 on a strong
note, rising to a four-year high versus the Japanese yen and two-and-a-half year
highs versus the Deutsche mark and the Swiss franc.  However, the dollar
underwent two significant corrections during the year.  The first correction
occurred in the Spring against the Japanese yen, due to the G7 finance
ministers' determination that a further dollar advance would be counter-
productive to their current goals.  From August through mid-November, the dollar
corrected against the Eurocurrencies in advance of a well-advertised tightening
by the Bundesbank.  By mid-December the dollar had bounced back to new highs
against the yen and was rallying against the mark.

          Global interest rate markets began the year on a volatile note, as
investors evaluated economic data for signs of inflation. By the middle of the
year, economic data in key countries was positive indicating lower inflation and
igniting a worldwide rally in the bond markets.  Specifically, investor
sentiment was particularly strong in the U.S., where prices on the 30-year
Treasury bond and 10-year Treasury note rose to their highest levels in over two
years.  This followed a largely positive economic report delivered by Federal
Reserve Chairman Greenspan in testimony before Congress.  Effects of the plunge
in the Hong Kong stock market in late October spread rapidly throughout the
world's financial markets, including global bond markets.  After continued
volatility in subsequent months made trading difficult, 1997 interest rate
trading ended on a positive note when U.S. and Japanese bond markets rallied as
a flight to safety from plunging stock markets around the world occurred in
December.

          In energy markets, a slump in crude oil prices was characteristic of
its lackluster performance from the beginning of the year.  Early in 1997,
volatility returned in the energy markets, reflecting the impact of a winter
significantly warmer than normal.  By mid-year, the decline in prices reversed
sharply as Saudi Arabia and Iran, together representing about 45% of OPEC's oil
production, joined forces to pressure oil-producing nations to stay within OPEC
production quotas.  In December, financial and economic problems in Asia reduced
demand for oil, and in combination with ample supplies, resulted in crude oil
prices declining once again.

     PERFORMANCE OVERVIEW

     The principal variables which determine the net performance of the
Partnership are gross profitability and interest income.  During all periods set
forth under "Selected Financial Data," the interest rates in many countries were
at unusually low levels.  This negatively impacted revenue because interest
income is typically a major component of commodity pool profitability.  In
addition, low interest rates are frequently associated with reduced fixed income
market volatility, and in static markets the Fund's profit potential generally
tends to be diminished.  On the other hand, during periods of higher interest
rates, the relative attractiveness of a high risk investment such as the Fund
may be reduced as compared to high yielding and much lower risk fixed-income
investments.

     The Partnership's Brokerage Commissions and Administrative Fees are a
constant percentage of assets allocated to trading. The only Fund costs (other
than the insignificant F/X Desk service fees, EFP differentials and
organizational and offering cost reimbursement payments as well as bid-ask
spreads on forward contracts) which are not based on a percentage of the Fund's
assets allocated to trading are the Profit Shares payable to the Trading
Advisors on an Advisor-by-Advisor basis.  During periods when Profit Shares are
a high percentage of net trading gains, it is likely that there has been
substantial performance non-correlation among Advisors (so that the total Profit
Shares paid to those Advisors which have traded profitably are a high
percentage, or perhaps even in excess,  of total profits recognized, as other
Advisors have incurred offsetting losses, reducing overall trading gains but not
the Profit Shares paid to successful Advisors) -- suggesting the likelihood of
generally trendless, non-consensus markets.

                                      -17-
<PAGE>

     The events that primarily determine the Partnership's profitability are
those that produce sustained and major price movements. The Advisors are
generally more likely to be able to profit from sustained trends, irrespective
of their direction, than from static markets. During the course of the
Partnership's performance to date, such events have ranged from Federal Reserve
Board reductions in interest rates, the apparent refusal of Iraq to arrive at a
settlement which would permit it to sell oil internationally, the inability of
the U.S. government to agree upon a federal budget, and a combination of drought
and excessive rain negatively impacting U.S. agricultural harvesting as well as
planting.  While these events are representative of the type of circumstances
which materially affect the Fund, the specific events which will do so in the
future cannot be predicted or identified.

     Unlike many investment fields, there is no meaningful distinction in the
operation of the Fund between realized and unrealized profits.  Most of the
contracts traded by the Fund are highly liquid and can be closed out at any
time.  Furthermore, the profits on many open positions are effectively realized
on a daily basis through the payment of variation margin.

     Except in unusual circumstances, factors -- regulatory approvals, cost of
goods sold, employee relations and the like -- which often materially affect an
operating business have virtually no impact on the Fund.

     THE DIFFERENT SERIES OF UNITS

     All series of Units issued after July 16, 1996 begin trading with the same
percentage (75%) of their total capital allocated to trading (by investment in
the Trading Partnership).  All Series issued prior to such date began trading
with 60% of their total capital allocated to trading.  All series trade in a
common trading account and are subject to the same method of calculating their
fees.  Furthermore, any discretionary action taken by MLIP -- e.g., making a
distribution or adjusting trading leverage -- must be done in such a way, that
all Units receive the same distributions (if any) as well as having the same
percentage of capital allocated to trading after the adjustment.  Despite these
fundamental similarities among the different series, because the series begin
trading at different times they are likely to come, as a result of trading
profits and losses, to have different percentages of their capital allocated to
trading, pay different Profit Shares (although to the same group of Advisors)
and have different Net Asset Values.

     LIQUIDITY AND CAPITAL RESOURCES

     The amount of capital raised for the Fund should not, except at extremely
high levels of capitalization,  have a significant impact on its operations.
The Fund's costs are generally proportional to its asset base and, within broad
ranges of capitalization, the Advisors' trading positions (and the resulting
gains and losses) should increase or decease in approximate proportion to the
size of the Fund account managed by each of them, respectively.

     The Partnership raises additional capital only through the continuous
offering of its Units.

     Inflation per se is not a significant factor in the Fund's profitability,
although inflationary cycles can give rise to the type of major price movements
that can have a materially favorable or adverse impact on the Fund's
performance.

     Changes in the level of prevailing interest rates could have a material
effect on the Fund's trading leverage.  Interest rates directly affect the
calculation of the discounted value (discounted back from the relevant Principal
Assurance Date)  of the guaranteed $100 minimum Net Asset Value per Unit and,
accordingly, the assets which a given series of Units has available for trading.

     In its trading to date, the Fund has from time to time had substantial
unrealized gains and losses on its open positions.  These gains or losses are
received or paid on a periodic basis as part of the routine clearing cycle on
exchanges or in the over-the-counter markets (the only over-the-counter market
in which the Fund trades is the inter-bank forward market in currencies).  In
highly unusual circumstances, market illiquidity could make it difficult for
certain Advisors to close out open positions, and any such illiquidity could
expose the Fund to significant losses, or cause it to be unable to recognize
unrealized gains.  However, in general, there is no meaningful difference
between the Fund's realized and unrealized gains.



     THE YEAR 2000 COMPUTER ISSUE

     Merrill Lynch's modifications for Year 2000 systems compliance are
proceeding according to plan and are expected to be completed in early 1999.
Based on information currently available, the remaining expenditures are
estimated at $200 million and will cover hardware and software upgrades, systems
consulting, and computer maintenance.  These expenditures are not expected to
have a material adverse impact on Merrill Lynch's financial position, results of
operations, or cash flows in future periods.  However, the failure of Merrill
Lynch's securities exchanges, clearing organizations, vendors, clients, or
regulators to resolve their own processing issues in a timely manner could
result in a material financial risk.  Merrill Lynch is devoting necessary
resources to address all Year 2000 issues in a timely manner.
