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 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 CASH RESERVES


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 and (2) ongoing costs, including management fees; distribution and
service 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 July 31, 2005.

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 N Hypothetical          1,000.00          1,018.45          6.43

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 181/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended July 31, 2005 are as follows:

CLASS         EXPENSE RATIOS
- ----------------------------
Class A           1.00%
- ----------------------------
Class B           1.23
- ----------------------------
Class C           1.29
- ----------------------------
Class N           1.28

The expense ratios reflect voluntary waivers or reimbursements of expenses by
the Fund's Manager and 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.

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

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

Oppenheimer Cash Reserves (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, Class B, Class C and Class N shares. Class A
shares are sold at their offering price, which is the net asset value per share
without any initial sales charge. Class B, Class C and Class N shares are sold
without a front-end sales charge but may be subject to a contingent deferred
sales charge (CDSC). Class N shares are sold only through retirement plans.
Retirement plans that offer Class N shares may impose charges on those accounts.
All 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. Class A, B, C and N have separate distribution and/or service plans.
Class B shares will automatically convert to Class A shares six years after the
date of purchase.

      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.

The tax components of capital shown in the table below represent distribution
requirements the Fund must satisfy under the income tax regulations, losses the
Fund may be able to offset against income and gains realized in future years for
federal income tax purposes.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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. Accordingly, the
following amounts have been reclassified for July 31, 2005. Net assets of the
Fund were unaffected by the reclassifications.

The tax character of distributions paid during the years ended July 31, 2005 and
July 31, 2004 was as follows:

       ---------------------------------------------------------------
       Distributions paid from:
       Ordinary income                  $11,235,264         $1,097,313

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Board of Trustees has adopted a deferred
compensation plan for independent trustees that enables trustees 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
Trustee 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 Trustee. The Fund purchases shares of the funds selected for
deferral by the Trustee 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 trustees' 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


                         24 | OPPENHEIMER CASH RESERVES


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 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.

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

- --------------------------------------------------------------------------------
2. SHARES OF BENEFICIAL INTEREST

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 0.50% of the first $250 million of average annual net assets,
0.475% of the next $250 million, 0.45% of the next $250 million, 0.425% of the
next $250 million, and 0.40% of net assets in excess of $1 billion.

- --------------------------------------------------------------------------------
ADMINISTRATION SERVICES. The Fund pays the Manager a fee of $1,500 per year for
preparing and filing the Fund's tax returns.

- --------------------------------------------------------------------------------
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 year ended July 31, 2005, the Fund paid
$2,691,192 to OFS for services to the Fund.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLAN (12B-1) FEES. Under its General Distributor's
Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the Distributor)
acts as the Fund's principal underwriter in the continuous public offering of
the Fund's classes of shares.

- --------------------------------------------------------------------------------
SERVICE PLAN FOR CLASS A SHARES. The Fund has adopted a Service Plan for Class A
shares. It reimburses the Distributor for a portion of its costs incurred for
services provided to accounts that hold Class A shares. Reimbursement is made
quarterly at an annual rate of up to 0.20% of the average annual net assets of
Class A shares of the Fund. The Distributor currently uses all of those fees to
pay dealers, brokers, banks and other financial institutions quarterly for
providing personal services and maintenance of accounts of their customers that
hold Class A shares. Any unreimbursed expenses the Distributor incurs with
respect to Class A shares in any fiscal year cannot be recovered in subsequent
years. Fees incurred by the Fund under the Plan are detailed in the Statement of

is authorized to pay the Distributor an annual asset-based sales charge of 0.75%
per year on Class B and Class C shares and 0.25% per year on Class N shares. If
either the Class B, Class C or Class N plan


                         26 | OPPENHEIMER CASH RESERVES


is terminated by the Fund or by the shareholders of a class, the Board of
Trustees and its independent trustees must determine whether the Distributor
shall be entitled to payment from the Fund of all or a portion of the service
fee and/or asset-based sales charge in respect to shares sold prior to the
effective date of such termination. The Distributor's aggregate uncompensated
expenses under the plan at July 31, 2005 for Class N shares were $3,903,565.
Fees incurred by the Fund under the plans are detailed in the Statement of
Operations.

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

WAIVERS AND REIMBURSEMENTS OF EXPENSES. Effective December 6, 2002, the Manager
has agreed to limit the Fund's management fee to 0.40% of the Fund's average net
assets for each class of shares. As a result of this limitation the Fund was
reimbursed $574,443 for the year ended July 31, 2005. This expense limitation
can be amended or terminated at any time without advance notice.

      OppenheimerFunds Distributor, Inc. (OFDI) has voluntarily agreed to reduce
Class B and Class C Distribution and/or Service (12b-1) Fees by 0.25% of the
average annual net assets for each respective class of shares. During the year

shareholder servicing agent fees for all classes to 0.35% of average annual net
assets per class. Effective April 28, 2003, transfer agent fees for all classes

necessary to allow each class of the Fund to maintain a 7-day yield of at least
approximately 0.10%. During the year ended July 31, 2005, OFS waived $235,772,
$2,976, $46,896 and $69,786 for Class A, Class B, Class C and Class N shares,
respectively. This undertaking may be amended or withdrawn at any time.

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

As of July 31, 2005, 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 consolidated amended complaint has been filed as putative derivative and class
actions against the Manager, OFS and the Distributor, as well as 51 of the
Oppenheimer funds (as "Nominal Defendants") excluding the Fund, 30 present and
former Directors or Trustees and 8 present and former officers of the funds.
This complaint, initially filed in the U.S. District Court for the Southern
District of New York on January 10, 2005, and amended on March 4, 2005,
consolidates into a single action and amends six individual previously filed
putative derivative and class action complaints. Like those prior complaints,
the complaint alleges that the Manager charged excessive fees for distribution
and other costs, improperly used assets of the funds in the form of directed
brokerage commissions and 12b-1 fees to pay brokers to promote sales of the
funds, and failed to properly disclose the use of assets of the funds to make
those payments in violation of the Investment Company Act of 1940 and the
Investment Advisers Act of 1940. Also, like those prior complaints, the
complaint further alleges that by permitting and/or participating in those
actions, the Directors/Trustees and the Officers breached their fiduciary duties
to shareholders of the funds under the Investment Company Act of 1940 and at
common law. The complaint seeks unspecified compensatory and punitive damages,
rescission of the funds' investment advisory agreements, an accounting of all
fees paid, and an award of attorneys' fees and litigation expenses.

      The defendants believe that the allegations contained in the Complaints
are without merit and that they have meritorious defenses against the claims
asserted. The defendants intend to defend these lawsuits vigorously and to
contest any claimed liability. The defendants 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.

6. ACQUISITION OF OPPENHEIMER CAPITAL PRESERVATION FUND

On February 11, 2005, the Fund acquired all of the net assets of Oppenheimer
Capital Preservation Fund, pursuant to an Agreement and Plan of Reorganization
approved by the Oppenheimer Capital Preservation Fund shareholders on February
4, 2005. The Fund issued (at an exchange ratio of 9.998070 for Class A, 9.995744
for Class B, 9.996812 for Class C and 9.999209 for Class N of the Fund to one
share of Oppenheimer Capital Preservation Fund), 94,028,608; 11,780,832;
33,119,088 and 216,713,190 shares of beneficial interest for Class A, Class B,
Class C and Class N, respectively, valued at $94,028,608, $11,780,832,
$33,119,088 and $216,713,190 in exchange for the net assets, resulting in
combined Class A net assets of $432,051,460, Class B net assets of $157,185,707,
Class C net assets of $115,652,349 and Class N net assets of $278,664,281 on
February 11, 2005. The exchange qualified as a tax-free reorganization for
federal income tax purposes.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF OPPENHEIMER CASH RESERVES:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer Cash Reserves, including the statement of investments, as of July
31, 2005, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the five years in the period
then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

      We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Fund is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. Our audit includes consideration
of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of July 31, 2005, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audits provide a reasonable basis for
our opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Oppenheimer Cash Reserves as of July 31, 2005, the results of its operations for
the year then ended, the changes in its net assets for each of the two years in
the period then ended, and the financial highlights for each of the five years
in the period then ended, in conformity with accounting principles generally
accepted in the United States of America.

FEDERAL INCOME TAX INFORMATION  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
In early 2006, if applicable, shareholders of record will receive information
regarding all dividends and distributions paid to them by the Fund during
calendar year 2005. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.

      The foregoing information is presented to assist shareholders in reporting
distributions received from the Fund to the Internal Revenue Service. Because of
the complexity of the federal regulations which may affect your individual tax
return and the many variations in state and local tax regulations, we recommend
that you consult your tax advisor for specific guidance.

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

- --------------------------------------------------------------------------------
Each year, the Board of Trustees (the "Board"), including a majority of the
independent Trustees, is required to determine whether to renew the Fund's
advisory 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 advisory
agreement. The Board employs an independent consultant to prepare a report that
provides information, including comparative information, that the Board requests
for this purpose. In addition, the Board receives information throughout the
year regarding Fund services, fees, expenses and performance.

      NATURE AND EXTENT OF SERVICES. In considering the renewal of the Fund's
advisory agreement for the current year, the Board evaluated the nature and
extent of the services provided by the Manager and its affiliates. The Manager
provides the Fund with office space, facilities and equipment; administrative,
accounting, clerical, legal and compliance personnel; securities trading
services; oversight of third party service providers and 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.

      QUALITY OF SERVICES. The Board also considered the quality of the services
provided and the quality of the Manager's resources that were available to the
Fund. The Board noted 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 received regarding the experience and professional qualifications of the
Manager's personnel and the size and functions of its staff. The Board members
also considered their experiences as directors or trustees of the Fund and other
funds advised by the Manager. The Board received and reviewed 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. The Board was aware that there are alternatives
to retaining the Manager.

      PORTFOLIO MANAGEMENT SERVICES AND PERFORMANCE. In its evaluation of the
quality of the portfolio management services to be 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 and Mr. Weiss are primarily
responsible for the day-to-day management of the Fund's investments. Ms. Wolf
has been a manager of the Fund's portfolio since June 1998 and has been a Senior
Vice President of the Manager since June 2000. She is an officer of other
portfolios in the OppenheimerFunds complex. Mr. Weiss has been a manager of the
Fund's portfolio since July 2001 and has been a Vice President


                         32 | OPPENHEIMER CASH RESERVES


of the Manager since July 2001. He is also an officer of other portfolios in the
OppenheimerFunds complex. Ms. Wolf has had over 20 years of experience and Mr.
Weiss has had over five years of experience managing money market investments.

      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 also receives and reviews
comparative performance information regarding the Fund and other funds at each
Board meeting. The Board noted that the Fund's one-year, three-year, five-year
and ten-year performance were disappointing, although its expense-adjusted
performance was near or better than its peer group average over those periods.
The Board recognized that it had recently changed certain non-fundamental
investment restrictions. The Board also noted that in the recent environment of
low interest rates, the difference between rankings for money market funds was
very small and determined to allow the Manager additional time to improve
performance.

      MANAGEMENT FEES AND EXPENSES. The Board also reviewed information,
including comparative information, regarding the fees paid to the Manager and
its affiliates and the other expenses borne by the Fund. The independent
consultant provided comparative data in regard to the fees and expenses of the
Fund and other money market funds with comparable asset levels and distribution
features. The Manager has agreed to limit the Fund's management fees to 0.40% of
the Fund's average net assets for each class of shares. That expense limitation
can be amended or terminated at any time without advance notice. The Board noted
that the Fund's contractual management fees and total expenses are higher than
its peer group average. However the Fund's actual management fees are lower than
its peer group average. In addition, the Board evaluated the comparability of
the fees charged and the services provided to the Fund to the fees charged and
services provided to other types of entities advised by the Manager. The Board
requested the Manager to provide recommendations for reducing Fund expenses.

      PROFITABILITY OF THE MANAGER AND AFFILIATES. The Board also reviewed
information regarding the cost of services provided by the Manager and its
affiliates and the Manager's profitability. 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. In
addition the Board considered information that was provided 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.

      ECONOMIES OF SCALE. The Board reviewed the extent to which the Manager may
realize economies of scale in managing and supporting the Fund and the current
level of Fund assets in relation to the Fund's breakpoint schedule for its
management fees. The Board considered that the Fund has not experienced any
recent asset growth and that, based on current asset levels, the Fund has not
yet passed its last management fee breakpoint.

      CONCLUSIONS. These factors were also considered by the independent
Trustees meeting separately from the full Board, assisted by experienced counsel
to the Fund and to the independent Trustees. Fund counsel and the independent
Trustees' counsel are both 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 and
considerations described above, the Board, including a majority of the
independent Trustees, 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 FUNDS' GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.    The Funds' 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
(as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR
270.30a-3(c)) as of July 31, 2005, the registrant's principal executive officer
and principal financial officer found the registrant's disclosure controls and
procedures to provide reasonable assurances that information required to be
disclosed by the registrant in the reports that it files under the Securities
Exchange Act of 1934 (a) is accumulated and communicated to registrant's
management, including its principal executive officer and principal financial
officer, to allow timely decisions regarding required disclosure, and (b) is
recorded, processed, summarized and reported, within the time periods specified
in the rules and forms adopted by the U.S. Securities and Exchange Commission.

There have been no changes in the registrant's internal controls over financial
reporting that



occurred during the registrant's second fiscal quarter of the period covered by
this report that have materially affected, or are reasonably likely to
materially affect, the registrant's internal control over financial reporting.

ITEM 12. EXHIBITS.

(a)   (1) Exhibit attached hereto.

      (2) Exhibits attached hereto.

      (3) Not applicable.

(b)   Not applicable.

                                   SIGNATURES

Pursuant to the requirements of the Securities Exchange Act of 1934 and the
Investment Company Act of 1940, the registrant has duly caused this report to be
signed on its behalf by the undersigned, thereunto duly authorized.
