                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                   ------------------------------------------

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
   ------------------------------------------

   These consolidated financial statements have been prepared without audit.  In
   the opinion of management, the consolidated financial statements contain all
   adjustments (consisting of only normal recurring adjustments) necessary to
   present fairly the financial position of ML JWH Strategic Allocation Fund L.P
   (the "Partnership" or the "Fund") as of June 30, 1999, and the results of its
   operations for the three and six month periods ended June 30, 1999 and 1998.
   However, the operating results for the interim periods may not be indicative
   of the results expected for the full year.

   Certain information and footnote disclosures normally included in annual
   financial statements prepared in accordance with generally accepted
   accounting principles have been omitted. It is suggested that these financial
   statements be read in conjunction with the financial statements and notes
   thereto included in the Partnership's Annual Report on form 10-K filed with
   the Securities and Exchange Commission for the year ended December 31, 1998
   (the "Annual Report").

2. FAIR VALUE AND OFF-BALANCE SHEET RISK

   In June 1998, the Financial Accounting Standards Board issued Statement of
   Financial Accounting Standard ("SFAS") No. 133, "Accounting for Derivative
   Instruments and Hedging Activities" (the "Statement"), effective for fiscal
   years beginning after June 15, 2000, however, the Fund has adopted the
   Statement effective January 1, 1999. This Statement supercedes SFAS No. 119
   ("Disclosure about Derivative Financial Instruments and Fair Value of
   Financial Instruments") and SFAS No. 105 ("Disclosure of information about
   Financial Instruments with Off-Balance Sheet Risk and Financial Instruments
   with Concentrations of Credit Risk") whereby disclosure of average aggregate
   fair values and contract/notional values, respectively, of derivative
   financial instruments is no longer required for an entity such as the
   Partnership which carries its assets at fair value.  Such Statement sets
   forth a much broader definition of a derivative instrument.  The General
   Partner does not believe that the application of the provisions of such
   statement has a significant effect on the financial statements.

   SFAS No. 133 defines a derivative as a financial instrument or other
   contract that has all three of the following characteristics (1) one or more
   underlyings, notional amounts or payment provisions (2) requires no initial
   net investment or a smaller initial net investment than would be required
   relative to changes in market factors (3) terms require or permit net
   settlement.  Generally, derivatives include a future, forward, swap or option
   contract, or other financial instrument with similar characteristics such as
   caps, floors and collars.

   Market Risk
   -----------

   Derivative instruments involve varying degrees of off-balance sheet market
   risk, and 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 frequently result in
   changes in the Partnership's net unrealized profit (loss) on such derivative
   instruments as reflected in the Consolidated Statements of Financial
   Condition.  The Joint Venture's exposure to market risk is influenced by a
   number of factors, including the relationships among the derivative
   instruments held by the Joint Venture as well as the volatility and liquidity
   in the markets in which such derivative instruments are traded.

   The General Partner has procedures in place intended to control market risk
   exposure, although there can be no assurance that they will, in fact, succeed
   in doing so.  The procedures focus primarily on monitoring the trading of JWH
   and reviewing outstanding positions for over-concentrations.  While the
   General Partner will not itself intervene in the markets to hedge or
   diversify the Joint Venture's market exposure, the General Partner may urge
   JWH to reallocate positions in an attempt to avoid over-concentrations.
   However, such interventions are unusual.  Except in cases in which it appears
   that JWH has begun to deviate from past practice and trading policies or to
   be trading erratically (which has not occurred to date), the General
   Partner's basic risk control procedures consist simply of monitoring JWH,
   with the market risk controls being applied by JWH itself.

                                       5
<PAGE>

   Credit Risk
   -----------

   The risks associated with exchange-traded contracts are typically perceived
   to be less than those associated with over-the-counter transactions (non-
   exchange-traded), because exchanges typically (but not universally) provide
   clearinghouse arrangements in which the collective credit (in some cases
   limited in amount, in some cases not) 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 their respective individual counterparties.  Margins, which may be
   subject to loss in the event of a default, are generally required in exchange
   trading, and counterparties may require margin in the over-the-counter
   markets.

   The credit risk associated with these instruments from counterparty non-
   performance is the net unrealized profit included on the Consolidated
   Statements of Financial Condition.

   The Joint Venture has credit risk in respect to its counterparties and
   brokers, but attempts to control this risk by dealing almost exlusively with
   Merrill Lynch entities as counterparties and brokers.

Performance Summary

January 1, 1998 to June 30, 1998
--------------------------------

January 1, 1998 to March 31, 1998

Much of the first quarter of 1998 offered a less-than-ideal trading environment
for the Fund.  In January and February, well-established trends in key markets
were interrupted, and many markets traded within a tight range, reducing
opportunities for profit.  But the profit picture improved in March, as the U.S.
dollar and other currencies returned to their prior patterns of price movement.

For the period, losses were incurred in positions in most currencies, metals,
stock indices and agricultural commodities.  These losses more than offset gains
in energy markets which, despite interim turbulence, ultimately succumbed to the
bearish fundamentals which have pressured prices downward for over nine months.
Small gains were also recorded in positions in European interest rates, which
continued to decline as markets of the EMU nations converged.

The quarter began with political and financial scandals in Japan.  Even so,
investors were hopeful  that the Japanese government would rescue the nation's
economy with a much-anticipated economic stimulus package.  Investor optimism
supported the Nikkei and caused the Japanese yen to gain against the U.S.
dollar.  Positions in the Nikkei and the yen were unprofitable.  January was
also a month of reversals in key metals.  The price of gold rose as the dollar
weakened, turning profitable positions in the metal into losses.  Gains were
recorded in European and U.S. government bond markets and in crude oil.

Financial markets lacked direction in February.  Losses were incurred in nearly
all currencies traded.  Trading was also unprofitable in U.S. Treasury bonds,
which traded within a narrow range during the month.  Gains continued to be
recorded, however, in European bond markets where yields approached post-war
lows.  The silver market hit a 9  1/2 year high on news that a major investor
had purchased 20% of the world's yearly mining output.  Strong gains were
realized in silver and in crude oil, which succumbed to weakening fundamentals.

The quarter ended with a sharp revival of the U.S. dollar in world markets,
especially against the yen, and a soaring British pound, which investors viewed
as a safe haven from EMU jitters.  Investment programs with large currency
components benefited from decisive moves in these markets as well as in the
Swiss franc and German mark.  The price of crude oil rose sharply during the
month, following the surprise decision by OPEC and non-OPEC oil-producing
nations to cut production.  By month end, however, investors had judged the
cutbacks insufficient and prices fell back; positions in energy markets were
profitable overall.  Positions in metals and agricultural commodities were
unprofitable overall.

April 1, 1998 to June 30, 1998

Investor optimism regarding developments in Japan dissipated rapidly in the
second quarter, as economic reports grew bleak.  Performance of the Fund
reflected the erratic behavior of the markets as investors grappled with the
possible impact of a Japanese recession on diverse global markets.  Losses were
incurred overall in the three month period ended June 30, 1998, despite strong
gains realized in May.

The quarter began with trendless trading conditions in financial markets as
prospects for interest rate hikes in the U.S. and Germany gave stock and bond
markets on both sides of the Atlantic a good case of the jitters.  Interventions
by the Bank of Japan to support the Japanese yen kept the currency markets on
edge for much of the month.  Gains in some agricultural commodities traded
failed to offset losses in financial markets.  The Fund recorded strong gains in
May, however, as financial market trends showed more definition.  Gains were
substantial overall in positions on the yen, which hit a seven year low against
the U.S. dollar.

In a move that surprised the markets, the U.S. and Japan jointly intervened on
June 17 on behalf of the Japanese currency, selling dollars and buying yen in
global foreign exchange markets.  The impact on the Fund was sharp, if

                                       7
<PAGE>
brief. Losses were incurred in short positions on the yen, as the Japanese
currency rose against the dollar. But by month's end, the market had returned to
fundamentals, and yen losses were reversed, resulting in small gains in the
currency overall. Nonetheless, the Fund's performance was spotty in June, with
moderate losses recorded overall for the month.

Despite U.S./Japan intervention, the Fund realized sizeable gains in positions
on the yen in the second quarter.  Positions in the Japanese Government bond,
where yields declined to historic lows, also resulted in strong gains in the
quarter, as did positions in short sterling; but these gains failed to offset
losses in other interest rate markets traded.

Also in the second quarter, the Fund recorded solid gains in crude oil positions
as prices fell on ample world supply.  Profitable positions  in coffee, sugar,
corn and wheat offset losses in other agricultural commodities traded in the
period.  With the exception of London Metals Exchange aluminum, positions in
other metals traded resulted in losses overall, as did positions in stock
indices.

January 1, 1999 to June 30, 1999
--------------------------------
January 1, 1999 to March 31, 1999

ML JWH Strategic Allocation Fund L.P. (the "Fund") recorded slight losses in the
three month period ended March 31, 1999, largely reflecting poor performance in
the interest rate and metals market sectors.

Interest rate markets for the first part of the quarter moved upward; however,
March saw a significant decline in European rates as an economic slowdown became
more evident in the European Union. The expectation, realized in early April,
was that the European Central Bank (ECB) would lower rates in Europe to provide
a more favorable interest rate environment. Coupled with the change in direction
in European markets, there was increased volatility in Japanese interest rate
markets as the Bank of Japan switched from interest rate targeting to a monetary
growth targeting policy. In an effort to stem the current recession, Japanese
policy officials have attempted various fiscal and monetary stimuli, which have
caused significant directional changes in interest rates. U.S. interest rates
have continued to inch upward for the quarter. There are few signs that the U.S.
economy will slow during 1999.

Commodity markets have had mixed performance. Metals markets have been choppy
for the entire quarter and have not exhibited any clear trends. This lack of
direction has caused poor performance in the precious metals area to be somewhat
offset by base metal profits. The energy sector performed well for the quarter
with a major trend developing in March. Since the beginning of March there has
been a significant upward trend in crude oil prices. Agriculture commodities
experienced mixed performance with many markets showing potential signs of
reversal. Overall, the Fund had slight losses in these markets.

Currencies have provided positive performance for the Fund. A continuation of
the strong dollar, especially relative to the new euro, offset some of the
losses in other markets. Contrary to the belief of many investment banking
economists, the euro has not started out as a strong currency and there seems to
be little flow into this new potential reserve currency. With a decline of over
seven percent for the quarter, the euro has not lived up to its potential
expectations.

Index performance was positive for the quarter with early losses offset by
significant gains in March with the increase in the Nikkei stock index.

On the balance for the quarter, profitable positions in global currencies,
energy, and agricultural commodities were offset by losses in interest rates and
metals.

April 1, 1999 to June 30, 1999

Interest rate markets followed a consistent pattern throughout the quarter
toward lower prices as strong economic growth in the U.S. was coupled by fears
of Federal Reserve bias to higher interest rates.  Long-term rates rose above
the 6% mark leading to the highest interest rates in over a year.  Though only
taking a neutral policy stand at the end of the quarter, the Fed raised rates 25
basis points on June 30.  Europe, though having overall slower growth also
showed the same trend toward higher rates especially in the last two months.
This rise in longer-term yields came in spite of a rate cut by the European
Central Bank in early April in an effort to stem the slowing growth in key
economies.

Commodity markets have had mixed performance. While many agricultural
commodities have continued to show a downtrend, the descent has been muted and
volatility has picked up as markets headed into the key summer season. In spite
of the lackluster trend performance in many agricultural commodities, there was
good performance from both the gold market and energy complexes.  The gold
market has been in steep decline after the Bank of England announced that it
would begin auctioning some of its gold reserves starting in July.  The energy
markets also have shown favorable trends with oil prices continuing their upward
trend.

Currencies have provided positive performance for the Fund with the decline in
the euro that began with its introduction at the beginning of the year still in
place. The key European currency has fallen from $1.17 to below $1.03 since the
beginning of the year.  The yen has been rangebound for the more recent period
caused by intervention by the Bank of Japan which has tried to stop the yen from
appreciating.  Other key currencies have not shown as significant trends as the
euro and thus had a smaller contribution to overall performance.

                                       8

The Nikkei index continued to show upward trends during the quarter in response
to the latest economic numbers that suggest the Japanese economy is firming
after its long decline.

YEAR 2000 COMPLIANCE

As the Year 2000 approaches, Merrill Lynch has undertaken initiatives to address
the Year 2000 problem (the "Y2K problem"), as more fully described in the
Partnership's 1998 Form 10-K.  The failure of Merrill Lynch's technology systems
relating to a Y2K problem would likely have a material adverse effect on the
company's business, results of operations, and financial condition.  This effect
could include disruption of normal business transactions, such as the
settlement, execution, processing, and recording of trades in securities,
commodities, currencies, and other assets.  The Y2K problem could also increase
Merrill Lynch's exposure to risk and legal liability and its need for liquidity.

The renovation phase of Merrill Lynch's Year 2000 system efforts, as described
in the Partnership's 1998 Form 10-K, was 100% completed as of June 30, 1999, and
production testing was 100% completed as of that date. In March and April 1999,
Merrill Lynch successfully participated in U.S. industrywide testing sponsored
by the Securities Industry Association. These tests involved an expanded number
of firms, transactions, and conditions compared with those previously conducted.
Merrill Lynch has participated in and continues to participate in numerous
industry tests throughout the world.

In light of the interdependency of the parties in or serving the financial
markets, there can be no assurance that all Y2K problems will be identified and
remedied on a timely basis or that all remediation will be successful. Public
uncertainty regarding successful remediation of the Y2K problem may cause a
reduction in activity in the financial markets. Disruption or suspension of
activity in the world's financial markets is also possible. In some non-U.S.
markets in which Merrill Lynch does business, the level of awareness and
remediation efforts relating to the Y2K problem are thought to be less advanced
than in the U.S. Management is unable at this point to ascertain whether all
significant third parties will successfully address the Y2K problem. Merrill
Lynch will continue to monitor third parties' Year 2000 readiness to determine
if additional or alternative measures are necessary. Contingency plans have been
established for all business units. However, the failure of exchanges, clearing
organizations, vendors, service providers, clients and counterparties,
regulators, or others to resolve their own processing issues in a timely manner
could have a material adverse effect on Merrill Lynch's business, results of
operations, and financial condition.

As of June 25, 1999, the total estimated expenditures of existing and
incremental resources for the Year 2000 compliance initiative are approximately
$520 million. This estimate includes $104 million of occupancy, communications,
and other related overhead expenditures, as Merrill Lynch is applying a fully
costed pricing methodology for this project. Of the total estimated
expenditures, approximately $80 million remains to be spent, primarily on
continued testing, contingency planning, and risk management. There can be no
assurance that the costs associated with remediation efforts will not exceed
those currently anticipated by Merrill Lynch, or that the possible failure of
such remediation efforts will not have a material adverse effect on Merrill
Lynch's business, results of operations, or financial condition.
