- --------------------------------------------------------------------------------
 1. SIGNIFICANT ACCOUNTING POLICIES
 Oppenheimer Money Market Fund, Inc. (the Fund) is registered under the
 Investment Company Act of 1940, as amended, as an open-end management
 investment company. The Fund's investment objective is to seek the maximum
 current income that is consistent with stability of principal. The Fund's
 investment advisor is OppenheimerFunds, Inc. (the Manager).
    The following is a summary of significant accounting policies consistently
 followed by the Fund.

- --------------------------------------------------------------------------------
 SECURITIES VALUATION. Portfolio securities are valued on the basis of amortized
 cost, which approximates market value.

- --------------------------------------------------------------------------------
 FEDERAL TAXES. The Fund intends to comply with provisions of the Internal
 Revenue Code applicable to regulated investment companies and to distribute
 substantially all of its investment company taxable income, including any net
 realized gain on investments not offset by capital loss carryforwards, if any,
 to shareholders, therefore, no federal income or excise tax provision is
 required.

- --------------------------------------------------------------------------------
 DIRECTORS' COMPENSATION. The Fund has adopted an unfunded retirement plan for
 the Fund's independent directors. Benefits are based on years of service and
 fees paid to each director during the years of service. During the six months
 ended January 31, 2004, the Fund's projected benefit obligations were increased
 by $20,533 and payments of $28,366 were made to retired directors, resulting in
 an accumulated liability of $361,781 as of January 31, 2004.
    The Board of Directors has adopted a deferred compensation plan for
 independent directors, that enables directors to elect to defer receipt of all
 or a portion of the annual compensation they are entitled to receive from the
 Fund. Under the plan, deferred amounts are treated as though equal dollar
 amounts had been invested in shares of the Fund or are invested in other
 Oppenheimer funds selected by the Director. Deferral of directors' fees under
 the plan will not affect the net assets of the Fund, and will not materially
 affect the Fund's assets, liabilities or net investment income per share.
 Amounts will be deferred until distributed in accordance to the Plan.

- --------------------------------------------------------------------------------
 DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
 shareholders, which are determined in accordance with income tax regulations,
 are recorded on the ex-dividend date. Income distributions, if any, are
 declared daily and paid monthly. Capital gain distributions, if any, are
 declared and paid annually.

- --------------------------------------------------------------------------------
 EXPENSE OFFSET ARRANGEMENT. The reduction of custodian fees, if applicable,
 represents earnings on cash balances maintained by the Fund.

- --------------------------------------------------------------------------------
 SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
 Realized gains and losses on securities sold are determined on the basis of
 identified cost.



                    16 | OPPENHEIMER MONEY MARKET FUND, INC.



- --------------------------------------------------------------------------------
 OTHER. 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 reported amounts
 of assets and liabilities and disclosure of contingent assets and liabilities
 at the date of the financial statements and the reported amounts of income and
 expenses during the reporting period. Actual results could differ from those
 estimates.


- --------------------------------------------------------------------------------
 2. SHARES OF CAPITAL STOCK
 The Fund has authorized five billion shares of $.10 par value capital stock.
 Transactions in shares of capital stock were as follows:

 MANAGEMENT FEES. Management fees paid to the Manager were in accordance with
 the investment advisory agreement with the Fund which provides for a fee at an
 annual rate of 0.45% of the first $500 million of aggregate net assets, 0.425%
 of the next $500 million of net assets, 0.40% of the next $500 million of net
 assets, 0.375% of the next $1.5 billion of net assets, and 0.35% of average
 annual net assets in excess of $3.0 billion.

 Manager, acts as the transfer and shareholder, servicing agent for the Fund.
 The Fund pays OFS a per account fee. For the six months ended January 31, 2004,
 the Fund paid $2,480,946 to OFS for services to the Fund.
    OFS has voluntarily agreed to limit transfer and shareholder servicing agent
 fees up to an annual rate of 0.35% of average net assets of the Fund. This
 undertaking may be amended or withdrawn at any time.

- --------------------------------------------------------------------------------
 4. ILLIQUID SECURITIES
 As of January 31, 2004, investments in securities included issues that are
 illiquid. A security may be considered illiquid if it lacks a readily available
 market or if its valuation has not changed for a certain period of time. The
 Fund intends to invest no more than 10% of its net assets (determined at the
 time of purchase and reviewed periodically) in illiquid securities. The
 aggregate value of illiquid securities subject to this limitation as of January
 31, 2004 was $76,100,000, which represents 4.23% of the Fund's net assets.
