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

Total returns include changes in share price and reinvestment of dividends and
capital gains distributions in a hypothetical investment for the periods shown.
Cumulative total returns are not annualized. The Fund's total returns shown do
not reflect the deduction of income taxes on an individual's investment. Taxes
may reduce your actual investment returns on income or gains paid by the Fund or
any gains you may realize if you sell your shares. 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.

The Fund's investment strategy and focus can change over time. The mention of
specific fund holdings does not constitute a recommendation by the Manager,
OppenheimerFunds, Inc.

The Fund has entered into a warranty agreement with Merrill Lynch Bank USA ("the
warranty provider") to make sure that the value of each shareholder's account on
the maturity date (December 16, 2011) will be at least equal to a shareholder's
original investment (reduced by any adjustments to the warranty amount permitted
by the Warranty Agreement, and less any redemptions of Fund shares or
distributions taken in cash, sales charges, and extraordinary Fund expenses).
The warranty is solely the obligation of the warranty provider to the Fund, not
to shareholders. The warranty does not guarantee performance of the Fund. The
ability of the Fund to maintain the value of your original investment is
dependent on the ability of the warranty provider to make a payment to the Fund
on the maturity date.

The principal risks of an investment in the Fund during the Warranty Period and
the Post-Warranty Period are those generally attributable to investing in stocks
and debt securities. Because the Fund invests in both stocks and debt securities
during the Warranty Period, the Fund may underperform stock funds when stocks
are in favor and underperform bond funds when debt securities are in favor.


            13 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III



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

Shareholders could lose money by investing in this Fund. A shareholder's
warranted amount will be reduced, as more fully described in the prospectus, if
the shareholder takes any dividends or distributions in cash instead of
reinvesting them in additional shares of the Fund, redeems any shares before the
Maturity Date, if there are extraordinary expenses incurred by the Fund (as such
expenses are not covered by the Warranty Agreement), if the Fund or the Manager
fails to perform certain obligations under the Warranty Agreement, or if the
warranty provider fails to or is unable to meet its obligations under the
Warranty Agreement.

The warranty is solely the obligation of the warranty provider. It is possible
that the financial position of the warranty provider may deteriorate.
Shareholders could lose money if the warranty provider fails to or is unable to
perform its obligations under the warranty. The Fund's assets and the
obligations of the warranty provider are not guaranteed by Merrill Lynch & Co.,
Inc. (the warranty provider's parent company), the United States Government, the
Manager or any other entity or person. The lack of a guarantee of the warranty
provider's obligations under the warranty presents some risks to shareholders if
the warranty provider fails or is unable to honor its obligations to the Fund on
the Maturity Date under the warranty.

Distributions from the Fund are taxable whether or not you reinvest them in
additional shares of the Fund. The warranty provider's obligation to make
payment to the Fund is not guaranteed by any entity and the Fund is not
obligated to replace the warranty provider should it be unable to make the
payments necessary to support the warranted amount. The warranty agreement fees
increase the Fund's expenses that you pay and therefore the expenses of this
Fund will be higher than the expenses of a Fund that does not offer principal
protection.

The Fund offered its shares to the public from October 7, 2004 to December 10,
2004. From December 16, 2004, and until December 16, 2011, shares of the Fund
will only be issued upon reinvestment of dividends and distributions.

An explanation of the calculation of performance is in the Fund's Statement of
Additional Information.

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

FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1)
transaction costs, which may include sales charges (loads) on purchase payments,
contingent deferred sales charges on redemptions; and redemption fees, if any;
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 February 28, 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


            15 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III



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

the Statement of Additional Information). 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            1,017.50          7.38

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 181/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended February 28, 2006 are as follows:

CLASS      EXPENSE RATIOS
- -------------------------
Class A         1.24%
- -------------------------
Class B         2.07
- -------------------------
Class C         1.99
- -------------------------
Class N         1.47

The expense ratios reflect voluntary waivers or reimbursements of expenses by
the Fund's Manager 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 Principal Protected Main Street Fund III (the Fund), a series of
Oppenheimer Principal Protected Trust III, is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
During the Warranty Period, the Fund will seek capital preservation in order to
have a net asset value on the Maturity Date at least equal to the Warranty
Amount. The Fund seeks high total return as a secondary objective. The Fund's
investment advisor is OppenheimerFunds, Inc. (the Manager).

      Shares of the Fund were offered during the Offering Period (October 7,
2004 to December 10, 2004). Shares are not offered during the Warranty Period
(December 16, 2004 to December 16, 2011) to the Maturity Date (December 16,
2011) except in connection with reinvestment of dividends and distributions.
During the Warranty Period, the Fund will allocate its assets between
Oppenheimer Main Street Fund (the Underlying Fund) and certain U.S. government
securities. The Fund offered Class A, Class B, Class C and Class N shares. Class
A shares were sold at their offering price, which is normally net asset value
plus a front-end sales charge. Class B and Class C shares were sold without a
front-end sales charge but may be subject to a contingent deferred sales charge
(CDSC). Class N shares were sold only through retirement plans. 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 90 months after the date of purchase.

      The following is a summary of significant accounting policies consistently
followed by the Fund.

- --------------------------------------------------------------------------------
WARRANTY AGREEMENT. The Fund has entered into a Financial Warranty Agreement
with Merrill Lynch Bank USA ("the Warranty Provider") to ensure that on the
Maturity Date each shareholder's account will be no less than the value of that
shareholder's account on the second business day after the end of the Offering
Period (the Warranty Amount). This value will include net income, if any, earned
by the Fund during the offering period and be reduced by adjustments permitted
under the Warranty Agreement, sales charges, applicable share of extraordinary
expenses and proportionately reduced for dividends and distributions paid in
cash and redemptions of Fund shares. To avoid a reduced Warranty Amount,
shareholders must reinvest all dividends and distributions received from the
Fund to purchase additional shares of the Fund and must not redeem any shares of
the Fund during the Warranty Period. If the value of the Fund's assets on the
Maturity Date is insufficient to result in the value of each shareholder's
account being at least equal to the shareholder's Warranty Amount, the Warranty
Provider will pay the Fund an amount equal to the excess of his or her Warranty
Amount over his or her account value.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

The Financial Warranty is solely the obligation of the Warranty Provider. It is
possible that the financial position of the Warranty Provider may deteriorate
and it would be unable to satisfy its obligations under the Financial Warranty.
The Fund's assets and the obligations of the Warranty Provider under the
Warranty Agreement are not guaranteed by Merrill Lynch & Co., Inc. (the Warranty
Provider's parent company), the United States Government, the Manager, or any
other entity or person.

      The Warranty Agreement requires the Manager, on behalf of the Fund, to
comply with certain agreed upon investment parameters in an attempt to limit the
Fund's risk. If the Manager fails to comply with the agreed-upon investment
parameters or otherwise fails to comply with certain requirements set forth in
the Warranty Agreement, the Warranty Provider may terminate its Financial
Warranty in certain limited circumstances. The Warranty Provider may monitor the
Fund's compliance with the Warranty Agreement solely to protect the interests of
the Warranty Provider and not the Fund's shareholders. The fee paid to the
Warranty Provider is an annual fee of 0.60% of the average daily net assets of
the Fund. If the Fund is required to make a complete and irreversible allocation
of its assets to the debt portfolio, the Warranty Fee will thereafter be reduced
to 0.35% of the average daily net assets of the Fund.

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The allocation of the Fund's assets between the debt
portfolio and the equity portfolio will vary over time based upon the Warranty
Formula. The formula is intended to allow the Fund to have a net asset value on
the Maturity Date at least equal to the Warranty Amount.

      During the Warranty Period, the Fund will invest a portion of its assets,
and in certain circumstances, the Fund may invest all of its assets, in U.S.
government securities having maturities approximately equal to the period
remaining in the Warranty Period. Long-term debt securities having a remaining
maturity in excess of sixty days will be valued at the mean between the "bid"
and "asked" prices. Long-term and short-term "non-money market" debt securities
are valued by a portfolio pricing service approved by the Board of Trustees.
Short-term "money market type" debt securities with remaining maturities of
sixty days or less are valued at amortized cost (which approximates market
value).

      The Fund may invest most of the equity portfolio in Class Y shares of
Oppenheimer Main Street Fund (the Underlying Fund). The net asset value of the
Underlying Fund is determined as of the close of the New York Stock Exchange
(the Exchange), normally 4:00 P.M. Eastern time, on each day the Exchange is
open for business. The net asset value per share is determined by dividing the
value of the Fund's net assets attributable to a class by the number of shares
of that class that are outstanding. The Fund may also invest a portion of the
equity portfolio in futures contracts. Futures contracts traded on a commodities
or futures exchange will be valued at the final settlement price or official
closing price on the principal exchange as reported by such principal exchange
at its trading session ending at, or most recently prior to, the time when the
Fund's assets are valued.

- --------------------------------------------------------------------------------
JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated funds
advised by the Manager, may transfer uninvested cash balances into joint trading
accounts on a daily basis. These balances are invested in one or more repurchase
agreements. Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements mature. Each agreement requires that
the market value of the collateral be sufficient to cover payments of interest
and principal. In the event of default by the other party to the agreement,
retention of the collateral may be subject to legal proceedings.


- --------------------------------------------------------------------------------
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, 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.

      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 February 28, 2006, the Fund had available for federal income tax
purposes an estimated capital loss carryforward of $1,055,870 expiring by 2014.
This estimated capital loss carryforward represents carryforward as of the end
of the last fiscal year, increased for losses deferred under tax accounting
rules to the current fiscal year and is increased or decreased by capital losses
or gains realized in the first six months of the current fiscal year. As of
February 28, 2006, it is estimated that the Fund will not utilize any capital
loss carryforward to offset realized capital gains. During the year ended August
31, 2005, the Fund did not utilize any capital loss carryforward to offset
capital gains realized in that fiscal period.

      As of August 31, 2005, the Fund had available for federal income tax
purposes post-October losses of $668,436.

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

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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 and capital gain distributions, if
any, are declared and paid annually.

- --------------------------------------------------------------------------------
INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon
ex-dividend notification in the case of certain foreign dividends where the
ex-dividend date may have passed. Non-cash dividends included in dividend
income, if any, are recorded at the fair market value of the securities
received. Interest income, which includes accretion of discount and amortization
of premium, is accrued as earned.

- --------------------------------------------------------------------------------
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
trustees 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.


            28 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III



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

- -------------------------------------------------------------------------
4. 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 average annual net assets of the Fund. That fee will
apply during the Warranty Period and the Post-Warranty Period. The management
fee shall be reduced to 0.40% per annum of average annual net assets of the Fund
in any month during the Warranty Period following a month where the Fund's
investment in equity securities (including shares of the Underlying Fund) is, on
average, less than 10% of net assets, If during the Warranty Period 100% of the
Fund's assets are completely and irreversibly invested in the debt portfolio,
the management fee will be at an annual rate of 0.25% of the average annual net
assets of the Fund, and if that occurs the Manager will further reduce its
management fee to the extent necessary so that expenses after waivers and
reductions to the Fund (other than Extraordinary Expenses such as litigation
costs) do not exceed 1.30% for Class A shares, 2.05% for Class B shares, 2.05%
for Class C shares and 1.55% for Class N shares. However, if this reduction in
the management fee is not sufficient to reduce expenses after waivers and
reducitons to these limits, the Manager is not required to subsidize Fund
expenses to assure that expenses do not exceed those limits. Furthermore, if
expenses exceed these expense limits, the Warranty Amount will be reduced by any
expenses that exceed those limits.

- --------------------------------------------------------------------------------
ADMINISTRATION SERVICE FEES. 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 six months ended February 28, 2006, the Fund paid
$29,182 to OFS for services to the Fund.

- --------------------------------------------------------------------------------
OFFERING AND ORGANIZATIONAL COSTS. The Manager paid all offering and
organizational costs associated with the registration and seeding of 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.


            30 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III



- --------------------------------------------------------------------------------
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
periodically at an annual rate of up to 0.25% 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 periodically 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
periods. Fees incurred by the Fund under the plan are detailed in the Statement
of Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The Fund
has adopted Distribution and Service Plans for Class B, Class C and Class N
shares to compensate the Distributor for its services in connection with the
distribution of those shares and servicing accounts. Under the plans, the Fund
pays the Distributor an annual asset-based sales charge of 0.75% on Class B and
Class C shares and 0.25% on Class N shares. The Distributor also receives a
service fee of 0.25% per year under each plan. If either the Class B, Class C or
Class N plan 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 February 28, 2006 for Class B and Class
N shares were $654,316 and $11,114, respectively. Fees incurred by the Fund
under the plans are detailed in the Statement of Operations.

- --------------------------------------------------------------------------------
SALES CHARGES. Front-end sales charges and 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 sales charges retained by the
Distributor from the sale of shares and the CDSC retained by the Distributor on
the redemption of shares is shown in the table below for the period indicated.

- --------------------------------------------------------------------------------
WAIVERS AND REIMBURSEMENTS OF EXPENSES. The Manager will reimburse the Fund for
expenses equal to the Underlying Fund expenses paid by the Fund as a shareholder
of the Underlying Fund. That expense reimbursement will fluctuate as the Fund's
allocation between the Underlying Fund and the debt portfolio changes. During
the six months ended February 28, 2006, the Manager reimbursed the Fund $96,276
for such Underlying Fund expenses.

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued

      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. This
undertaking may be amended or withdrawn at any time.

- --------------------------------------------------------------------------------
5. FUTURES CONTRACTS

A futures contract is a commitment to buy or sell a specific amount of a
commodity or financial instrument at a negotiated price on a stipulated future
date. Futures contracts are traded on a commodity exchange. The Fund may invest
in futures contracts on the S&P 500 Index to maintain liquity to meet
shareholder redemptions and minimize trading costs. The Fund seeks to maintain a
position in futures contracts on the S&P 500 Index sufficient to allow the Fund
to increase or decrease the percentage of the Fund's assets invested in the
equity portfolio as permitted by the Warranty Agreement with minimal impact on
the trading activities of the Underlying Fund.

      Upon entering into a futures contract, the Fund is required to deposit
either cash or securities (initial margin) in an amount equal to a certain
percentage of the contract value. Subsequent payments (variation margin) are
made or received by the Fund each day. The variation margin payments are equal
to the daily changes in the contract value and are recorded as unrealized gains
and losses. The Fund recognizes a realized gain or loss when the contract is
closed or has expired.

      Cash held by the broker to cover initial margin requirements on open
futures contracts is noted in the Statement of Assets and Liabilities.
Securities held in collateralized accounts to cover initial margin requirements
on open futures contracts are noted in the Statement of Investments. The
Statement of Assets and Liabilities reflects a receivable and/or payable for the
daily mark to market for variation margin. Realized gains and losses are
reported in the Statement of Operations as the closing and expiration of futures
contracts. The net change in unrealized appreciation and depreciation is
reported in the Statement of Operations.

      Risks of entering into futures contracts (and related options) include the
possibility that there may be an illiquid market and that a change in the value
of the contract or option may not correlate with changes in the value of the
underlying securities.

As of February 28, 2006, the Fund had outstanding futures contracts as follows:



                              EXPIRATION   NUMBER OF     VALUATION AS OF     UNREALIZED

6. LITIGATION

A complaint was filed as a putative class action against the Manager and the
Transfer Agent (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. The complaint alleged, among other things, that the Manager charged
excessive fees for distribution and other costs, and that by permitting and/or
participating in those actions, the Directors/Trustees and the Officers of the
funds breached their fiduciary duties to fund shareholders under the Investment
Company Act of 1940 and at common law. The plaintiffs sought unspecified
damages, an accounting of all fees paid, and an award of attorneys' fees and
litigation expenses. Seven of the eight counts in the complaint, including the
claims against certain of the Oppenheimer funds, 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, by
court order dated March 10, 2006, in response to motions to dismiss the suit
that had been filed by the defendants. The remaining count against the Manager
and the Transfer Agent was dismissed with prejudice by court order dated April
5, 2006. The time in which plaintiffs may file an appeal to those decisions has
not yet lapsed.

the Fund votes proxies relating to securities ("portfolio proxies") held by the
Fund. A description of the Fund's Portfolio Proxy Voting Policies and Procedures
is available (i) without charge, upon request, by calling the Fund toll-free at
1.800.525.7048, (ii) on the Fund's website at www.oppenheimerfunds.com, and

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
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, including an analysis of the
cost of providing services, (v) whether 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. Outlined below is a summary of the principal information considered by the
Board as well as the Board's conclusions.

      NATURE, QUALITY, 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
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.

      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 fact


            35 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III



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

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 key personnel and the size and functions of its staff providing
investment management services to the Fund. The Board also considered compliance
reports from the Fund's Chief Compliance Officer. In its evaluation of the
quality of the portfolio management services provided, the Board considered the
experience of Angelo Manioudakis and Rudi Schadt and the Manager's Investment
Grade investment team and analysts. Messrs. Manioudakis and Schadt have had over
14 and 13 years of experience, respectively, managing fixed income, equity,
international and risk management investments. The Board members also considered
the totality of their experiences with the Manager, as directors or trustees of
the Fund and other funds advised by the Manager. 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 balanced target maturity funds
(including both funds advised by the Manager and funds advised by other
investment advisers). The Board noted that the Fund's performance had been below
its peer group average during the period since its inception in October 2004.
The Board also considered that the Fund had low equity exposure during that
initial period and that its portfolio allocation had shifted to a nearly 50%
equity allocation. The Board concluded that it was reasonable to allow the
Manager additional time to develop the Fund's performance record, given the
Fund's recent inception date.

      COSTS OF SERVICES AND PROFITS REALIZED BY 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 reviewed the fees
paid to the Manager and the other expenses borne by the Fund, including the
Fund's fee and expense reduction and reimbursement arrangements. The Board also
evaluated the comparability of the fees charged and the services provided to the
Fund to the fees and services for other clients or accounts advised by the
Manager.


            36 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III



The independent consultant provided comparative data in regard to the fees and
expenses of the Fund, other balanced target maturity funds and other funds with
comparable asset levels and distribution features. The Board noted that the
Fund's contractual and actual management fees and its total expenses are all
lower than its peer group median and average. In light of this, the Board
concluded that the management fee was reasonable.

      ECONOMIES OF SCALE. The Board reviewed whether the Fund's advisory fee
shares with shareholders economies of scale that the Manager may realize in
managing and supporting the Fund. The Board noted the Fund's shares are not
being offered for sale after the offering period.

      OTHER BENEFITS TO THE MANAGER. In addition to considering the profits
realized by the Manager, 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. The Board also 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.

      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
described above, the Board, including a majority of the independent Trustees,
decided 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.

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Main Street Fund (the Fund) is a separate series of Oppenheimer Main
Street Funds, Inc., an open-end management investment company registered under
the Investment Company Act of 1940, as amended. The Fund's investment objective
is to seek a high total return. The Fund's investment advisor is
OppenheimerFunds, Inc. (the Manager).

      The Fund offers Class A, Class B, Class C, Class N and Class Y shares.
Class A shares are sold at their offering price, which is normally net asset
value plus a front-end 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. Class Y shares are sold to certain institutional investors without
either a front-end sales charge or a CDSC, however, the institutional investor
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. No such plan has been adopted for
Class Y shares. 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. The Fund calculates the net asset value of its shares as
of the close of the New York Stock Exchange (the Exchange), normally 4:00 P.M.
Eastern time, on each day the Exchange is open for business. Securities may be
valued primarily using dealer-supplied valuations or a portfolio pricing service
authorized by the Board of Directors. Securities listed or traded on National
Stock Exchanges or other domestic exchanges are valued based on the last sale
price of the security traded on that exchange prior to the time when the Fund's
assets are valued. Securities traded on NASDAQ are valued based on the closing
price provided by NASDAQ prior to the time when the Fund's assets are valued. In
the absence of a sale, the security is valued at the last sale price on the
prior trading day, if it is within the spread of the closing "bid" and "asked"
prices, and if not, at the closing bid price. Securities traded on foreign
exchanges are valued based on the last sale price on the principal exchange on
which the security is traded, as identified by the portfolio pricing service,
prior to the time when the Fund's assets are valued. In the absence of a sale,
the security is valued at the official closing price on the principal exchange.
Corporate, government and municipal debt instruments having a remaining maturity
in excess of sixty days and all mortgage-backed securities will be valued at the
mean between the "bid" and "asked" prices. Futures contracts traded on a
commodities or futures exchange will be valued at the final settlement price or
official closing price on the principal exchange as reported by such principal
exchange at its trading session

1. SIGNIFICANT ACCOUNTING POLICIES Continued

ending at, or most recently prior to, the time when the Fund's assets are
valued. Securities (including restricted securities) for which market quotations
are not readily available are valued at their fair value. Foreign and domestic
securities whose values have been materially affected by what the Manager
identifies as a significant event occurring before the Fund's assets are valued
but after the close of their respective exchanges will be fair valued. Fair
value is determined in good faith using consistently applied procedures under
the supervision of the Board of Directors. Short-term "money market type" debt
securities with remaining maturities of sixty days or less are valued at
amortized cost (which approximates market value).

- --------------------------------------------------------------------------------
FOREIGN CURRENCY TRANSLATION. The Fund's accounting records are maintained in
U.S. dollars. The values of securities denominated in foreign currencies and
amounts related to the purchase and sale of foreign securities and foreign
investment income are translated into U.S. dollars as of the close of the New
York Stock Exchange (the Exchange), normally 4:00 P.M. Eastern time, on each day
the Exchange is open for business. Foreign exchange rates may be valued
primarily using dealer supplied valuations or a portfolio pricing service
authorized by the Board of Directors.

      Reported net realized foreign exchange gains or losses arise from sales of
portfolio securities, sales and maturities of short-term securities, sales of
foreign currencies, currency gains or losses realized between the trade and
settlement dates on securities transactions, and the difference between the
amounts of dividends, interest, and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains and losses arise from changes in the
values of assets and liabilities, including investments in securities at fiscal
period end, resulting from changes in exchange rates.

      The effect of changes in foreign currency exchange rates on investments is
separately identified from the fluctuations arising from changes in market
values of securities held and reported with all other foreign currency gains and
losses in the Fund's Statement of Operations.

- --------------------------------------------------------------------------------
JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated funds
advised by the Manager, may transfer uninvested cash balances into joint trading
accounts on a daily basis. These balances are invested in one or more repurchase
agreements. Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements mature. Each agreement requires that
the market value of the collateral be sufficient to cover payments of interest
and principal. In the event of default by the other party to the agreement,
retention of the collateral may be subject to legal proceedings.

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


            62 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III



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, 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.

      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 February 28, 2006, the Fund had available for federal income tax
purposes an estimated capital loss carryforward of $146,721,072 expiring by
2014. This estimated capital loss carryforward represents carryforward as of the
end of the last fiscal year, increased for losses deferred under tax accounting
rules to the current fiscal year and is increased or decreased by capital losses
or gains realized in the first six months of the current fiscal year. As of
February 28, 2006, it is estimated that the Fund will utilize $522,391,497 of
capital loss carryforward to offset realized capital gains. During the year
ended August 31, 2005, the Fund did utilize $557,605,412 of capital loss
carryforward to offset capital gains realized in that fiscal year. a

      a. Includes $489,935 of capital loss carryforwards acquired in the
      September 4, 2003 merger of Oppenheimer Trinity Core Fund.

As of August 31, 2005, the Fund had available for federal income tax purposes
unused capital loss carryforward as follows:

                        EXPIRING
                        --------------------------
                        2011          $669,112,569

- --------------------------------------------------------------------------------
DIRECTORS' COMPENSATION. 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.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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 and capital gain distributions, if
any, are declared and paid annually.

- --------------------------------------------------------------------------------
INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon
ex-dividend notification in the case of certain foreign dividends where the
ex-dividend date may have passed. Non-cash dividends included in dividend
income, if any, are recorded at the fair market value of the securities
received. Interest income, which includes accretion of discount and amortization
of premium, is accrued as earned.

- --------------------------------------------------------------------------------
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. At February 28, 2006, the Fund had $1,602 of such earnings on
cash balances available to offset future custodian fees or interest expenses
incurred during the next fiscal year.

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

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

- --------------------------------------------------------------------------------
4. FEES AND OTHER TRANSACTIONS WITH AFFILITATES

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 0.65% of the first $200 million of average annual net assets of
the Fund, 0.60% of the next $150 million, 0.55% of the next $150 million, and
0.45% of average annual net assets in excess of $500 million.

- --------------------------------------------------------------------------------
ADMINISTRATION SERVICE FEES. 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 six months ended February 28, 2006, the Fund paid
$11,511,705 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.

- --------------------------------------------------------------------------------
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
periodically at an annual rate of up to 0.25% 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 periodically 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
periods. Fees incurred by the Fund under the plan are detailed in the Statement
of Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The Fund
has adopted Distribution and Service Plans for Class B, Class C and Class N
shares to compensate the Distributor for its services in connection with the
distribution of those shares and servicing accounts. Under the plans, the Fund
pays the Distributor an annual asset-based sales charge of 0.75% on Class B and
Class C shares and 0.25% on Class N shares. The Distributor also receives a
service fee of 0.25% per year under each plan. If either the Class B, Class C or
Class N plan is terminated by the Fund or by the shareholders of a class, the
Board of Directors and its independent directors 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


            66 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III



such termination. The Distributor's aggregate uncompensated expenses under the
plan at February 28, 2006 for Class B, Class C and Class N shares were
$29,620,181, $34,086,891 and $2,842,386, respectively. Fees incurred by the Fund
under the plans are detailed in the Statement of Operations.

- --------------------------------------------------------------------------------
SALES CHARGES. Front-end sales charges and 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 sales charges retained by the
Distributor from the sale of shares and the CDSC retained by the Distributor on
the redemption of shares is shown in the table below 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. This undertaking may be amended or
withdrawn at any time.

- --------------------------------------------------------------------------------
5. FOREIGN CURRENCY CONTRACTS

A foreign currency contract is a commitment to purchase or sell a foreign
currency at a future date, at a negotiated rate. The Fund may enter into foreign
currency contracts to settle specific purchases or sales of securities
denominated in a foreign currency and for protection from adverse exchange rate
fluctuation. Risks to the Fund include the potential inability of the
counterparty to meet the terms of the contract.

      The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using prevailing foreign currency exchange rates.
Unrealized appreciation and depreciation on foreign currency contracts are
reported in the Statement of Assets and Liabilities as a receivable or payable
and in the Statement of Operations with the change in unrealized appreciation or
depreciation.

      The Fund may realize a gain or loss upon the closing or settlement of the
foreign transaction. Contracts closed or settled with the same broker are
recorded as net realized gains or losses. Such realized gains and losses are
reported with all other foreign currency gains and losses in the Statement of
Operations.

      As of February 28, 2006, the Fund had no outstanding foreign currency
contracts.

- --------------------------------------------------------------------------------
6. ILLIQUID SECURITIES

As of February 28, 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.

- --------------------------------------------------------------------------------
7. SECURITIES LENDING

The Fund lends portfolio securities from time to time in order to earn
additional income. In return, the Fund receives collateral in the form of U.S.
Treasury obligations or cash, against the loaned securities and maintains
collateral in an amount not less than 100% of the market value of the loaned
securities during the period of the loan. The market value of the loaned
securities is determined at the close of business of the funds and any
additional required collateral is delivered to the Fund on the next business
day. If the borrower defaults on its obligation to return the securities loaned
because of insolvency or other reasons, the Fund could experience delays and
cost in recovering the securities loaned or in gaining access to the collateral.
Cash collateral is invested in cash equivalents. The Fund retains a portion of
the interest earned from the collateral. The Fund continues to receive the
economic benefit of interest or dividends paid on the securities loaned in the
form of a substitute payment received from the borrower. As of February 28,
2006, the Fund had on loan securities valued at $27,967,782. Collateral of
$28,809,743 was received for the loans, all of which was received in cash and
subsequently invested in approved instruments.

- --------------------------------------------------------------------------------
8. LITIGATION

A complaint was filed as a putative class action against the Manager and the
Transfer Agent (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. The complaint alleged, among other things, that the Manager charged
excessive fees for distribution and other costs, and that by permitting and/or
participating in those actions, the Directors/ Trustees and the Officers of the
funds breached their fiduciary duties to fund shareholders under the Investment
Company Act of 1940 and at common law. The plaintiffs sought unspecified
damages, an accounting of all fees paid, and an award of attorneys' fees and
litigation expenses. Seven of the eight counts in the complaint, including the
claims against certain of the Oppenheimer funds, 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, by
court order dated March 10, 2006, in response to motions to dismiss the suit
that had been filed by the defendants. The remaining count against the Manager
and the Transfer Agent was dismissed with


            68 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III



prejudice by court order dated April 5, 2006. The time in which plaintiffs may
file an appeal to those decisions has not yet lapsed.

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
(as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR
270.30a-3(c)) as of February 28, 2006, 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.
