NOTES
- --------------------------------------------------------------------------------

AN INVESTMENT IN THE FUND IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT
INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE FUND SEEKS TO
PRESERVE THE VALUE OF YOUR INVESTMENT AT $1.00 PER SHARE, IT IS POSSIBLE TO LOSE
MONEY BY INVESTING IN THE FUND.

THE FUND'S INVESTMENT STRATEGY, ALLOCATIONS, AND FOCUS CAN CHANGE OVER TIME. THE
MENTION OF SPECIFIC FUND HOLDINGS DOES NOT CONSTITUTE A RECOMMENDATION BY
OPPENHEIMERFUNDS, INC.

INVESTORS SHOULD CONSIDER THE FUND'S INVESTMENT OBJECTIVES, RISKS, AND OTHER
CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. THE FUND'S PROSPECTUS CONTAINS
THIS AND OTHER INFORMATION ABOUT THE FUND, AND MAY BE OBTAINED BY ASKING YOUR
FINANCIAL ADVISOR, CALLING US AT 1.800.525.7048 OR VISITING OUR WEBSITE AT
WWW.OPPENHEIMERFUNDS.COM. READ THE PROSPECTUS CAREFULLY BEFORE INVESTING.


                     8 | OPPENHEIMER MONEY MARKET FUND, INC.


FUND EXPENSES
- --------------------------------------------------------------------------------

FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1)
transaction costs, which may include contingent deferred sales charges on
redemptions, if any; and (2) ongoing costs, including management fees and other
Fund expenses. These examples are intended to help you understand your ongoing
costs (in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended January 31, 2006.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line for the class of shares you hold, together with the amount you invested, to
estimate the expense that you paid over the period. Simply divide your account
value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00
= 8.60), then multiply the result by the number in the "actual" line under the
heading entitled "Expenses Paid During Period" to estimate the expenses you paid
on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the Fund's actual expense ratio for each class of shares, and
an assumed rate of return of 5% per year before expenses, which is not the
Fund's actual return. The hypothetical account values and expenses may not be
used to estimate the actual ending account balance or expenses you paid for the
period. You may use this information to compare the ongoing costs of investing
in the Fund and other funds. To do so, compare this 5% hypothetical example for
the class of shares you hold with the 5% hypothetical examples that appear in
the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as front-end
or contingent deferred sales charges (loads), or a $12.00 fee imposed annually
on accounts valued at less than $500.00 (subject to exceptions described in the
Statement of Additional Information).

FUND EXPENSES
- --------------------------------------------------------------------------------

Therefore, the "hypothetical" lines of the table are useful in comparing ongoing
costs only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
costs would have been higher.

Class Y Hypothetical           1,000.00         1,022.86         2.38

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Fund's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 184/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended January 31, 2006 are as follows:

CLASS                    EXPENSE RATIOS
- ---------------------------------------
Class A                       0.61%
- ---------------------------------------
Class Y                       0.47

The expense ratios reflect voluntary waivers or reimbursements of expenses by
the Fund's Transfer Agent that can be terminated at any time, without advance
notice. The "Financial Highlights" tables in the Fund's financial statements,
included in this report, also show the gross expense ratios, without such
waivers or reimbursements.

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 Fund offers Class A and Class Y shares. Class A shares are sold at
their offering price, which is the net asset value per share without any initial
sales charge. Class Y shares are sold to certain institutional investors without
a front-end sales charge. Both classes of shares have identical rights and
voting privileges with respect to the Fund in general and exclusive voting
rights on matters that affect that class alone. Earnings, net assets and net
asset value per share may differ due to each class having its own expenses, such
as transfer and shareholder servicing agent fees and shareholder communications,
directly attributable to that class.

      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.

- --------------------------------------------------------------------------------
ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated on a
daily basis to each class of shares based upon the relative proportion of net
assets represented by such class. Operating expenses directly attributable to a
specific class are charged against the operations of that class.

- --------------------------------------------------------------------------------
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 to shareholders,
therefore, no federal income or excise tax provision is required.

      Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Fund.

      As of January 31, 2006, it is estimated that the Fund will not utilize any
capital loss carryforward to offset realized capital gains. During the year
ended July 31, 2005, the Fund did not utilize any capital loss carryforward to
offset capital gains realized in that fiscal year.

- --------------------------------------------------------------------------------
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, 2006, the Fund's projected benefit obligations were decreased
by $13,912 and payments of

NOTES TO FINANCIAL STATEMENTS Unaudited / Continued

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES Continued

$30,185 were made to retired directors, resulting in an accumulated liability of
$312,138 as of January 31, 2006.

      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.
For purposes of determining the amount owed to the Director under the plan,
deferred amounts are treated as though equal dollar amounts had been invested in
shares of the Fund or in other Oppenheimer funds selected by the Director. The
Fund purchases shares of the funds selected for deferral by the Director in
amounts equal to his or her deemed investment, resulting in a Fund asset equal
to the deferred compensation liability. Such assets are included as a component
of "Other" within the asset section of the Statement of Assets and Liabilities.
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 but may be paid at other times to maintain the net asset value per
share at $1.00.

- --------------------------------------------------------------------------------
CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may
include interest expense incurred by the Fund on any cash overdrafts of its
custodian account during the period. Such cash overdrafts may result from the
effects of failed trades in portfolio securities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Fund pays
interest to its custodian on such cash overdrafts to the extent they are not
offset by positive cash balances maintained by the Fund at a rate equal to the
Federal Funds Rate plus 0.50%. The "Reduction to custodian expenses" line item,
if applicable, represents earnings on cash balances maintained by the Fund
during the period. Such interest expense and other custodian fees may be paid
with these earnings.

- --------------------------------------------------------------------------------
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.

- --------------------------------------------------------------------------------
INDEMNIFICATIONS. The Fund's organizational documents provide current and former
directors and officers with a limited indemnification against liabilities
arising in connection with the performance of their duties to the Fund. In the
normal course of business, the Fund may also enter into contracts that provide
general indemnifications. The Fund's maximum exposure under these arrangements
is unknown as this would be dependent on future claims that may be made against
the Fund. The risk of material loss from such claims is considered remote.


                    22 | OPPENHEIMER MONEY MARKET FUND, INC.


- --------------------------------------------------------------------------------
OTHER. The preparation of financial statements in conformity with U.S. generally
accepted accounting principles 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.

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

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.

- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. OppenheimerFunds Services (OFS), a division of the 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, 2006, the Fund paid
$1,866,165 to OFS for services to the Fund.

Additionally, Class Y shares are subject to minimum fees of $10,000 per annum
for assets of $10 million or more. The Class Y shares are subject to the minimum
fees in the event that the per account fee does not equal or exceed the
applicable minimum fees. OFS may voluntarily waive the minimum fees.

- --------------------------------------------------------------------------------
SALES CHARGES. Contingent deferred sales charges (CDSC) do not represent
expenses of the Fund. They are deducted from the proceeds of sales of Fund
shares prior to investment or from redemption proceeds prior to remittance, as
applicable. The CDSC retained by the Distributor on the redemption of shares is
shown in the following table for the period indicated.

WAIVERS AND REIMBURSEMENTS OF EXPENSES. OFS has voluntarily agreed to limit
transfer and shareholder servicing agent fees for all classes to 0.35% of
average annual net assets per class. During the six months ended January 31,
2006, OFS waived $11,307 for Class Y shares. This undertaking may be amended or
withdrawn at any time.

- --------------------------------------------------------------------------------
4. ILLIQUID SECURITIES

As of January 31, 2006, 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 will not invest more than 10% of its net assets (determined at the time of
purchase and reviewed periodically) in illiquid securities. Securities that are
illiquid are marked with the applicable footnote on the Statement of
Investments.

- --------------------------------------------------------------------------------
5. LITIGATION

A complaint was filed as a putative class action against the Manager and OFS
(and other defendants) in the U.S. District Court for the Southern District of
New York on January 10, 2005 and was amended on March 4, 2005. Seven of the
eight counts in the complaint, including claims against certain of the
Oppenheimer funds excluding the Fund, as nominal defendants, and against certain
present and former Directors, Trustees and officers of the funds, and the
Distributor, as defendants, were dismissed with prejudice, under a court order
dated March 10, 2006, in response to a motion to dismiss the suit that had been
filed by the defendants. The remaining count against the Adviser Defendants
alleges, among other things, that the defendants charged excessive fees in
violation of section 36(b) of the Investment Company Act of 1940. The plaintiffs
seek unspecified damages, an accounting of all fees paid, and an award of
attorneys' fees and litigation expenses.

      The Adviser Defendants believe that the claims asserted in the remaining
count under this lawsuit are without merit, and intend to defend the suit
vigorously and contest any claimed liability. They believe that it is premature
to render any opinion as to the likelihood of an outcome unfavorable to them and
that no estimate can yet be made with any degree of certainty as to the amount
or range of any potential loss.

BOARD APPROVAL OF THE FUND'S INVESTMENT
ADVISORY AGREEMENT Unaudited
- --------------------------------------------------------------------------------

Each year, the Board of Directors (the "Board"), including a majority of the
independent Directors, is required to determine whether to renew the Fund's
investment advisory agreement (the "Agreement"). The Investment Company Act of
1940, as amended, requires that the Board request and evaluate, and that the
Manager provide, such information as may be reasonably necessary to evaluate the
terms of the Agreement. The Board employs an independent consultant to prepare a
report that provides information, including comparative information that the
Board requests for that purpose. In addition, the Board receives information
throughout the year regarding Fund services, fees, expenses and performance.

      The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Fund and the Manager,
(iii) the fees and expenses of the Fund, including comparative expense
information, (iv) the profitability of the Manager and its affiliates, including
an analysis of the cost of providing services by the Manager and its affiliates,
(v) the extent to which economies of scale are realized as the Fund grows and
whether fee levels reflect these economies of scale for Fund investors and (vi)
other benefits to the Manager from its relationship with the Fund. The Board was
aware that there are alternatives to retaining the Manager.

      NATURE AND EXTENT OF SERVICES. The Board considered information on the
nature and extent of the services provided to the Fund and information regarding
the Manager's key personnel that provide such services. The Manager's duties
include providing the Fund with the services of the portfolio managers and the
Manager's investment team, who provide research, analysis and other advisory
services in regard to the Fund's investments; securities trading services;
oversight of third party service providers; monitoring compliance with
applicable Fund policies and procedures and adherence to the Fund's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Fund as well. Those services include providing, and supervising
the activities of, all administrative and clerical personnel that are necessary
in order to provide effective corporate administration for the Fund; compiling
and maintaining records with respect to the Fund's operations; preparing and
filing reports required by the Securities and Exchange Commission; preparing
periodic reports regarding the operations of the Fund for its shareholders;
preparing proxy materials for shareholder meetings; and preparing the
registration statements required by Federal and state securities laws for the
sale of the Fund's shares. The Manager also provides the Fund with office space,
facilities and equipment.

BOARD APPROVAL OF THE FUND'S INVESTMENT
ADVISORY AGREEMENT Unaudited / Continued
- --------------------------------------------------------------------------------

      QUALITY OF SERVICES. The Board also considered the quality of the services
provided and the quality of the Manager's resources that are available to the
Fund. The Board took account of the facts that the Manager has had over forty
years of experience as an investment adviser and that its assets under
management rank it among the top mutual fund managers in the United States. The
Board evaluated the Manager's administrative, accounting, legal and compliance
services, and information the Board has received regarding the experience and
professional qualifications of the Manager's personnel and the size and
functions of its staff. In its evaluation of the quality of the portfolio
management services provided, the Board considered the experience of Carol E.
Wolf and Barry D. Weiss and the Manager's Money Market investment team and
analysts. Ms. Wolf has had over 22 years and Mr. Weiss has had over six years of
experience managing money market investments. The Board members also considered
their experiences with the Manager and its officers and other personnel through
their service as directors or trustees of the Fund and other funds advised by
the Manager. The Board considered information regarding the quality of services
provided by affiliates of the Manager, which it also reviews at other times
during the year in connection with the renewal of the Fund's service agreements.
In light of the foregoing, the Board concluded that the Fund benefits from the
services provided under the Agreement as a result of the Manager's experience,
reputation, personnel, operations, and resources.

      INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. During the year, the
Manager provided information on the performance of the Fund and the Manager at
each Board meeting, including comparative performance information. The Board
also reviewed information, prepared by the Manager and by the independent
consultant, comparing the Fund's historical performance to relevant market
indices and to the performance of other money market funds advised by the
Manager and other investment advisers. The Board noted that the Fund's one-year
performance was better than its peer group average, however, its three-year,
five-year and ten-year performance were below its peer group average.

      MANAGEMENT FEES AND EXPENSES. The Board reviewed the fees paid to the
Manager and its affiliates and the other expenses borne by the Fund. The Board
also evaluated the comparability of the fees charged and the services provided
to the Fund to those of other clients or accounts advised by the Manager. The
independent consultant provided comparative data in regard to the fees and
expenses of the Fund, other money market funds and other funds with comparable
asset levels and distribution features. The Board noted that the Fund's
contractual and actual management fees and total expenses were higher than its
peer group average.


                    28 | OPPENHEIMER MONEY MARKET FUND, INC.


      ECONOMIES OF SCALE. The Board reviewed the extent to which the Manager may
realize economies of scale in managing and supporting the Fund, to what extent
those economies of scale benefit the Fund shareholders and the current level of
Fund assets. The Board also noted the Fund's breakpoints, which are intended to
share economies of scale that may exist as the Fund grows with its shareholders.

      PROFITS AND OTHER BENEFITS TO THE MANAGER. The Board considered
information regarding the Manager's costs in serving as the Fund's investment
adviser, including the costs associated with the personnel and systems necessary
to manage the Fund, and information regarding the Manager's profitability from
its relationship with the Fund. The Board considered that the Manager must be
able to pay and retain experienced professional personnel at competitive rates
to provide services to the Fund and that maintaining the financial viability of
the Manager is important in order for the Manager to continue to provide
significant services to the Fund and its shareholders. The Board also considered
information regarding the direct and indirect benefits the Manager receives as a
result of its relationship with the Fund, including compensation paid to the
Manager's affiliates for services provided.

      CONCLUSIONS. These factors were also considered by the independent
Directors meeting separately from the full Board, assisted by experienced
counsel to the Fund and the independent Directors. Fund counsel is independent
of the Manager within the meaning and intent of the Securities and Exchange
Commission Rules.

      Based on its review of the information it received and its evaluations
described above, the Board, including a majority of the independent Directors,
concluded that the nature, extent and quality of the services provided to the
Fund by the Manager are a benefit to the Fund and in the best interest of the
Fund's shareholders and that the amount and structure of the compensation
received by the Manager and its affiliates are reasonable in relation to the
services provided. Accordingly, the Board elected to continue the advisory
agreement for another year. In arriving at this decision, the Board did not
single out any factor or factors as being more important than others, but
considered all of the factors together. The Board judged the terms and
conditions of the advisory agreement, including the management fee, in light of
all of the surrounding circumstances.

THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.    The Fund's Governance Committee (the "Committee") will evaluate potential
      Board candidates to assess their qualifications. The Committee shall have
      the authority, upon approval of the Board, to retain an executive search
      firm to assist in this effort. The Committee may consider recommendations
      by business and personal contacts of current Board members and by
      executive search firms which the Committee may engage from time to time
      and may also consider shareholder recommendations. The Committee may
      consider the advice and recommendation of the Funds' investment manager
      and its affiliates in making the selection.

2.    The Committee shall screen candidates for Board membership. The Committee
      has not established specific qualifications that it believes must be met
      by a trustee nominee. In evaluating trustee nominees, the Committee
      considers, among other things, an individual's



      background, skills, and experience; whether the individual is an
      "interested person" as defined in the Investment Company Act of 1940; and
      whether the individual would be deemed an "audit committee financial
      expert" within the meaning of applicable SEC rules. The Committee also
      considers whether the individual's background, skills, and experience will
      complement the background, skills, and experience of other nominees and
      will contribute to the Board. There are no differences in the manner in
      which the Committee evaluates nominees for trustees based on whether the
      nominee is recommended by a shareholder.

3.    The Committee may consider nominations from shareholders for the Board at
      such times as the Committee meets to consider new nominees for the Board.
      The Committee shall have the sole discretion to determine the candidates
      to present to the Board and, in such cases where required, to
      shareholders. Recommendations for trustee nominees should, at a minimum,
      be accompanied by the following:

      o     the name, address, and business, educational, and/or other pertinent
            background of the person being recommended;

      o     a statement concerning whether the person is an "interested person"
            as defined in the Investment Company Act of 1940;

      o     any other information that the Funds would be required to include in
            a proxy statement concerning the person if he or she was nominated;
            and

      o     the name and address of the person submitting the recommendation
            and, if that person is a shareholder, the period for which that
            person held Fund shares.

      The recommendation also can include any additional information which the
      person submitting it believes would assist the Committee in evaluating the
      recommendation.

4.    Shareholders should note that a person who owns securities issued by
      Massachusetts Mutual Life Insurance Company (the parent company of the
      Funds' investment adviser) would be deemed an "interested person" under
      the Investment Company Act of 1940. In addition, certain other
      relationships with Massachusetts Mutual Life Insurance Company or its
      subsidiaries, with registered broker-dealers, or with the Funds' outside
      legal counsel may cause a person to be deemed an "interested person."

5.    Before the Committee decides to nominate an individual as a trustee,
      Committee members and other directors customarily interview the individual
      in person. In addition, the individual customarily is asked to complete a
      detailed questionnaire which is designed to elicit information which must
      be disclosed under SEC and stock exchange rules and to determine whether
      the individual is subject to any statutory disqualification from serving
      as a trustee of a registered investment company.

ITEM 11. CONTROLS AND PROCEDURES.



Based on their evaluation of the registrant's disclosure controls and procedures

financial officer, to allow timely decisions regarding required disclosure, and

likely to materially affect, the registrant's internal control over financial
