FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE FUND PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF
THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED AUGUST 31, 2005, FOLLOWED BY
A GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE BROAD-BASED
MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. For the since inception period
(October 7, 2004 through August 31, 2005), Oppenheimer Principal Protected Main
Street Fund III's(R) Class A shares had a total return of 1.76% which was below
the S & P 500 Index's total return of 9.71%. The Fund's main goal is not to
chase absolute returns, but to preserve investor's capital, while staying
competitive with its peers. The underperformance was due to the strong overall
stock market performance, especially in the end of 2004. During periods of
rising stock markets, principal protected funds tend to lag behind pure stock
market indices because they typically have less than 100% of their net assets
invested in the equity market.

      The equity component of the Fund's portfolio is invested in shares of
Oppenheimer Main Street Fund(R) and in S&P Futures. The use of S&P Futures as an
alternative equity instrument allows maintaining liquidity to meet shareholder
redemptions, minimizing trading costs, and taking advantage of possible
imbalances in stock market fair value. The fixed income component is invested
primarily in Treasury STRIPS that mature on or around the end of the seven-year
Warranty Period. 3 The asset allocation of the Oppenheimer Principal Protected
Main Street Fund III(R) will shift over time based on market factors such as
interest rates, stock market performance and certain volatility measures.
Additionally, there is a pre-defined algorithm that dictates the maximum
percentage the Fund can invest in equity securities. This algorithm is based in
part on current stock weightings and changes in the market environment
(including interest rates, stock market performance and volatility).

      OppenheimerFunds' risk management team monitors the Fund's asset
allocation and keeps the Fund's equity percentage dynamically set, depending on
market conditions. In an up stock market, the Fund buys shares of the underlying
fund to take advantage of stock market potential. In a down market, the Fund
sells shares of the underlying fund and buys Treasury STRIPS to help limit the
downside of the market. In a sideways market, the algorithm allows the Fund "to
stay still" in order to avoid unnecessary trading costs.

OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III MAY NOT BE SUITABLE FOR
INVESTORS WHO NEED TO REDEEM SHARES PRIOR TO MATURITY, OR WHO NEED TO RECEIVE
DIVIDENDS IN CASH.

3. The Fund invests a significant portion of assets in treasury strips, which
are sold at a discount and accrue to par value at maturity. For taxable income
purposes the discount on these treasury strips is amortized into income daily
using a level yield method over the holding period of the security, thus
investors will have taxable income.


            9 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III



FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

      The Fund began the protection period (12/16/2004) with 37.6% invested in
equity. As of 8/31/2005, the Fund has a 44.7% equity exposure 4 (through
Oppenheimer Main Street Fund(R) Class Y shares and the S&P Futures). The other
45.0% and 10.3% are invested in fixed income and in cash equivalents,
respectively.

      For the period October 7, 2004 through August 31, 2005, the Oppenheimer
Main Street Fund(R) Class Y shares produced a total return of 9.79%, which was
higher than the return of its benchmark, the S&P 500 Index, which returned
9.71%. Management of the underlying fund, the Oppenheimer Main Street Fund(R),
attributes this performance to stock selection and to the fact that its
overweight position in the Energy sector has more than offset its overweight in
the poorly performing Mega-Cap sector.

COMPARING THE FUND'S PERFORMANCE TO THE MARKET. The graphs that follow show the
performance of a hypothetical $10,000 investment in each class of shares of the
Fund held until August 31, 2005. In the case of Class A, Class B, Class C and
Class N shares, performance is measured from inception of the classes on
10/7/04. The Fund's performance reflects the deduction of the maximum initial
sales charge on Class A shares, the applicable contingent deferred sales charge
on Class B, Class C and Class N shares, and reinvestments of all dividends and
capital gains distributions. Past performance cannot guarantee future results.

      The Fund's performance is compared to the performance of the S&P 500
Index. The S&P 500 Index is an unmanaged index of equity securities. Index
performance reflects the reinvestment of income but does not consider the effect
of transaction costs, and none of the data in the graphs shows the effect of
taxes. The Fund's performance reflects the effects of the Fund's business and
operating expenses. While index comparisons may be useful to provide a benchmark
for the Fund's performance, it must be noted that the Fund's investments are not
limited to the investments in the index.

4. Please note that these official balance sheet equity weights do not include
S&P Futures positions since those are "marked to market", i.e. funds move in and
out of the Fund's Futures account every day as the value of the S&P Futures
contracts changes. The S&P Futures, together with Oppenheimer Main Street Fund
shares, contribute to the Fund's growth by taking advantage of stock market
growth potential. S&P Futures (on their notional value basis) contribute an
additional 9.7% to Fund's equity exposure, as of 8/31/2005.

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

Total returns and the ending account values in the graphs include changes in
share price and reinvestment of dividends and capital gains distributions in a
hypothetical investment for the periods shown. 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 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.

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 through 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 August 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


            17 | 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.

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Fund's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 184/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended August 31, 2005 are as follows:

CLASS             EXPENSE RATIOS
- --------------------------------
Class A                1.17%
- --------------------------------
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.


            26 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III



      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 invests 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.

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

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 and
unrealized appreciation or depreciation of securities and other investments for
federal income tax purposes.

1. As of August 31, 2005, the Fund had $668,436 of post-October losses available
to offset future realized capital gains, if any. Such losses, if utilized, will
expire in 2014.

2. During the fiscal year ended August 31, 2005, the Fund did not utilize any
capital loss carryforward.

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 August 31, 2005. Net assets of the
Fund were unaffected by the reclassifications.

31, 2005.

The aggregate cost of securities and other investments and the composition of
unrealized appreciation and depreciation of securities and other investments for
federal income tax purposes as of August 31, 2005 are noted below. The primary
difference between book and tax appreciation or depreciation of securities and
other investments, if applicable, is attributable to the tax deferral of losses
or tax realization of financial statement unrealized gain or loss.

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

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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 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.

- --------------------------------------------------------------------------------
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 total annual operating expenses
of 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 total annual operating expenses 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 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 period ended August 31, 2005, the Fund paid
$41,347 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.

- --------------------------------------------------------------------------------
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 0.25% 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 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
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% per year on
Class B and Class C shares and 0.25% per year 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 August 31, 2005
for Class B, Class C and Class N shares were $714,393, $37,278 and $12,501,
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 period ended August 31, 2005, the Manager reimbursed the Fund $139,710 for
such Underlying Fund expenses.

      The Manager voluntarily agreed to waive its management fee and assume all
expenses of the Fund, with the exception of the 12b-1fee, during the Offering
Period. During the period ended August 31, 2005, the Manager reimbursed the Fund
$32,897.

      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 buy and
sell futures contracts that relate to broadly based securities indices
(financial futures) or debt securities (interest rate futures) in order to gain
exposure to or protection from changes in market value of stocks and bonds or
interest rates. The Fund may also buy or write put or call options on these
futures contracts.

      The Fund generally sells futures contracts as a hedge against increases in
interest rates and decreases in market value of portfolio securities. The Fund
may also purchase futures contracts to gain exposure to market changes as it may
be more efficient or cost effective than actually buying securities.

      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 August 31, 2005, the Fund had outstanding futures contracts as follows:

6. 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.

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

- --------------------------------------------------------------------------------
TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF
OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer Principal Protected Main Street Fund III, a series of Oppenheimer
Principal Protected Trust III, including the statement of investments, as of
August 31, 2005, and the related statement of operations, the statement of
changes in net assets and the financial highlights for the period from October
7, 2004 (commencement of operations) to August 31, 2005. 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 August 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 Principal Protected Main Street Fund III as of August 31, 2005, the
results of its operations, the statement of changes in net assets and the
financial highlights for the period from October 7, 2004 (commencement of
operations) to August 31, 2005, 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.

      Dividends of $0.0468, $0.0182, $0.0226 and $0.0405 per share were paid to
Class A, Class B, Class C and Class N shareholders, respectively, on December
31, 2004, none of which was designated as a "capital gain distribution" for
federal income tax purposes.

      None of the dividends paid by the Fund during the year ended August 31,
2005 are eligible for the corporate dividend-received deduction.

      A portion, if any, of the dividends paid by the Fund during the fiscal
year ended August 31, 2005 which are not designated as capital gain
distributions are eligible for lower individual income tax rates to the extent
that the Fund has received qualified dividend income as stipulated by recent tax
legislation. $214,411 of the Fund's fiscal year taxable income may be eligible
for the lower individual income tax rates. In early 2006, shareholders of record
will receive information regarding the percentage of distributions that are
eligible for lower individual income tax rates.

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

- --------------------------------------------------------------------------------
The Investment Company Act 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. For the initial approval of the
Fund's investment advisory agreement, the Board considered the factors discussed
below.

      NATURE AND EXTENT OF SERVICES. In considering the initial approval of the
Fund's advisory agreement, the Board evaluated the nature and extent of the
services to be provided by the Manager and its affiliates. The investment
advisory agreement requires the Manager, at its expense, to provide the Fund
with office space, facilities and equipment; administrative, clerical, legal and
compliance personnel; marketing and sales support; securities trading services;
oversight of third party service providers and the services of the Manager's
Asset Allocation Team, who will provide advisory services in regard to the
Fund's investments.

      QUALITY OF SERVICES. The Board also considered the quality of the services
to be provided and the quality of the Manager's resources that will be 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 based on
information it has received regarding the experience and professional
qualifications of the Manager's personnel and the size and functions of its
staff. The Board also considered their own experiences as directors or trustees
of other funds advised by the Manager. The Board has also received and reviewed
information regarding the quality of services provided by affiliates of the
Manager at other times during the year, in connection with the renewal of those
affiliates' service agreements with other funds. 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 provided, the Board considered the
experience of the Fund's portfolio managers and the Manager's risk management
team, equity and balanced funds investment team and fixed income investment team
and analysts. The allocation of the Fund's assets between shares of Oppenheimer
Main Street Fund and fixed-income securities has been managed by Rudi Schadt
since the Fund's inception in October 2004. Mr. Schadt is a Vice President of
the Fund and a Vice President, Director of Research in Product Design and Risk
Management of the Manager. He has had over 12 years of risk management and
equity/global experience. The Fund's fixed-income component has been managed by
Angelo Manioudakis since the Fund's inception in October 2004. Mr. Manioudakis
is a Vice President of the Fund and a Senior Vice President of the


            38 | OPPENHEIMER PRINCIPAL PROTECTED MAIN STREET FUND III



Manager and has had over 12 years of experience managing fixed-income
investments. The Board also considered the historical performance of other funds
advised by the Manager.

      MANAGEMENT FEES AND EXPENSES. The Board considered information regarding
the fees to be paid to the Manager and its affiliates. The Board also considered
the other expenses that will be borne both directly and indirectly by the Fund
and the comparability of the fees and services of the Fund to the fees and
services of other types of entities advised by the Manager. The Board discussed
the services the Manager performs for Oppenheimer Main Street Fund and the
services the Manager will perform for the Fund and concluded that the advisory
fee to be charged is based on services provided that are in addition to, rather
than duplicative of, services provided under the investment advisory agreement
with Oppenheimer Main Street Fund. The Board also considered that the Manager
will reimburse the Fund for the full amount of its pro-rata share of the
expenses, other than extraordinary expenses, that it incurs from investing in
shares of Oppenheimer Main Street Fund.

      PROFITABILITY OF THE MANAGER AND AFFILIATES. The Board also considered the
cost of services to be provided by the Manager and its affiliates. 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 the potential direct and indirect
benefits the Manager may receive 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. The Board also
considered that the Manager has agreed to reduce its fees, in certain
circumstances, based on the percentage of the Fund's assets that is invested in
debt securities.

      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,
concluded that the nature, extent and quality of the services provided to the
Fund by the Manager would be a benefit to the Fund and would be in the best
interest of the Fund's shareholders and that

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

the amount and structure of the compensation to be received by the Manager and
its affiliates from the Fund are reasonable in relation to the services
provided. Accordingly, the Board approved the Fund's initial investment advisory
agreement. In arriving at a decision, the Board did not single out any one
factor or group of factors as being more important than other factors, but
considered all 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.

      registrant's investment adviser, and any entity controlling, controlled
      by, or under common control with the investment adviser that provides
      ongoing services to the registrant that were not pre-approved pursuant to
      paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with
      maintaining the principal accountant's independence.

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 August 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)   Exhibit attached hereto.



                                   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.
