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 DECEMBER 31, 2004, FOLLOWED
BY A GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE
BROAD-BASED MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. Oppenheimer Core Bond Fund
delivered a favorable, competitive yield and total return for the 12-month
period ended December 31, 2004, largely due to sector decisions and individual
security selection among both corporate bonds and mortgage-related securities,
with a small contribution from interest rate decisions. Throughout the period,
we maintained a healthy risk exposure to corporate, mortgage, and agency
securities. This increased exposure performed well for us since these securities
benefited for the year as demand continued to be robust and spreads versus
treasuries tightened over the year. Specifically, our individual security
selection within each of our sector allocations added to performance. For
example, within our mortgage-backed securities (MBS) holdings, our emphasis on
older, higher-coupon issues gave the Fund a clear advantage over the outstanding
mortgage universe, which generally emphasizes pools of lower-coupon mortgages
issued in the low interest-rate environment of the past few years. Their lower
coupon/yield offerings made those securities less and less appealing to
investors as rates began their ascent, and consequently, they underperformed
higher-coupon mortgages. While we did hold lower-coupon mortgages, we believed
it prudent to maintain a diversified mix of mortgage securities while
emphasizing one segment of the sector, as a way to better insulate the Fund from
unforeseen volatility.

      The second most significant benefit to Fund performance this fiscal year
came from our security selection within, as well as our overall emphasis on, the
corporate credit sector. Among corporate credits, our specific emphasis on
BBB-rated, or lower quality, corporate issues substantially supported
performance, as this segment of the corporate market outperformed the
higher-rated segments of the investment-grade credit universe. We enjoyed
particularly good performance from many of our media- and automotive-related
bonds, with these sectors generally leading the triple-B rated segment's rally.
Finally, our tactical allocation to high-yield, or "junk" bonds (3.3% of
assets), helped Fund performance, as these bonds not only gave a boost to the
Fund's yield, but continued to perform well in 2004.

      Active management of the Fund's interest-rate sensitivity, or duration,
also made a positive contribution to performance over the course of the year.
Twice during the period we repositioned the Portfolio from a neutral yield curve
stance to one that would benefit from a subsequent rise in interest rates. In
both instances our interest rate view was vindicated.

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

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 December 31, 2004. In the case of Class A and Class B shares,
performance is measured over a ten-fiscal-year period. In the case of Class C
shares, performance is measured from inception of the Class on July 11, 1995. In
the case of Class N shares, performance is measured from inception of the Class
on March 1, 2001. In the case of Class Y shares, performance is measured from
inception of the Class on April 27, 1998. 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.

      Beginning January 21, 2005, the Fund changed its primary benchmark index
from the Lehman Brothers Credit Index to the Citigroup Broad Investment Grade
Bond Index ("Citigroup Index") because the Fund believes that the Citigroup
Index is a more appropriate benchmark reflecting the types of securities in
which the Fund invests. The Citigroup Index consists of securities having a
higher grade and a lower modified duration than the securities in the Lehman
Brothers Credit Index.

      The Fund's performance is compared to the performance of its former
primary benchmark, the Lehman Brothers Credit Index, a broad-based, unmanaged
index of publicly-issued non-convertible investment grade corporate debt of U.S.
issuers, widely recognized as a measure of the U.S. fixed-rate corporate bond
market. Performance is also compared to its new primary benchmark, the Citigroup
Broad Investment Grade Bond Index, a market-capitalization weighted index that
includes fixed-rate Treasury, government-sponsored, corporate and mortgage
securities. The Fund has also added a secondary benchmark, the Lehman Brothers
Aggregate Bond Index, an unmanaged index of U.S. corporate and government bonds,
to which its performance is compared. 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.

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.

      CLASS A shares of the Fund were first publicly offered on 4/15/88. The
      Fund's maximum sales charge for Class A shares was lower prior to 3/29/91,
      so actual performance may have been higher. Unless otherwise noted, Class
      A returns include the current maximum initial sales charge of 4.75%.

      CLASS B shares of the Fund were first publicly offered on 5/3/93. Unless
      otherwise noted, Class B returns include the applicable contingent
      deferred sales charge of 5% (1-year) and 2% (5-year). Because Class B
      shares convert to Class A shares 72 months after purchase, the "10-year"
      return for Class B uses Class A performance for the period after
      conversion. Class B shares are subject to an annual 0.75% asset-based
      sales charge.

      CLASS C shares of the Fund were first publicly offered on 7/11/95. Unless
      otherwise noted, Class C returns include the contingent deferred sales
      charge of 1% for the 1-year period. Class C shares are subject to an
      annual 0.75% asset-based sales charge.

      CLASS N shares of the Fund were first publicly offered on 3/1/01. Class N
      shares are offered only through retirement plans. Unless otherwise noted,
      Class N returns include the contingent deferred sales charge of 1% for the
      1-year period. Class N shares are subject to an annual 0.25% asset-based
      sales charge.


                         18 | OPPENHEIMER CORE BOND FUND



      CLASS Y shares of the Fund were first publicly offered on 4/27/98. Class Y
      shares are offered only to certain institutional investors under special
      agreements with the Distributor.

      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
      December 31, 2004.

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

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

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


                         20 | OPPENHEIMER CORE BOND FUND



      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 184/366
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended December 31, 2004 are as follows:

CLASS                   EXPENSE RATIOS
- --------------------------------------
Class A                      0.90%

Class B                      1.65

- --------------------------------------
Class Y                      0.67

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

FOOTNOTES TO STATEMENT OF INVESTMENTS

1. Illiquid or restricted security. The aggregate value of illiquid or
restricted securities as of December 31, 2004 was $40,120,968, which represents
6.26% of the Fund's net assets, none of which is considered restricted. See Note
8 of Notes to Financial Statements.

2. Represents the current interest rate for a variable or increasing rate
security.

3. When-issued security or forward commitment to be delivered and settled after
December 31, 2004. See Note 1 of Notes to Financial Statements.

4. Interest-Only Strips represent the right to receive the monthly interest
payments on an underlying pool of mortgage loans. These securities typically
decline in price as interest rates decline. Most other fixed income securities
increase in price when interest rates decline. The principal amount of the
underlying pool represents the notional amount on which current interest is
calculated. The price of these securities is typically more sensitive to changes
in prepayment rates than traditional mortgage-backed securities (for example,
GNMA pass-throughs). Interest rates disclosed represent current yields based
upon the current cost basis and estimated timing and amount of future cash
flows. These securities amount to $15,460,082 or 2.41% of the Fund's net assets
as of December 31, 2004.

5. Principal-Only Strips represent the right to receive the monthly principal
payments on an underlying pool of mortgage loans. The value of these securities
generally increases as interest rates decline and prepayment rates rise. The
price of these securities is typically more volatile than that of coupon-bearing
bonds of the same maturity. Interest rates disclosed represent current yields
based upon the current cost basis and estimated timing of future cash flows.
These securities amount to $1,631,574 or 0.25% of the Fund's net assets as of
December 31, 2004.

6. All or a portion of the security is held in collateralized accounts to cover
initial margin requirements on open futures sales contracts with an aggregate
market value of $757,860. See Note 5 of Notes to Financial Statements.

7. Zero coupon bond reflects effective yield on the date of purchase.

8. Represents securities sold under Rule 144A, which are exempt from
registration under the Securities Act of 1933, as amended. These securities have
been determined to be liquid under guidelines established by the Board of
Trustees. These securities amount to $25,947,127 or 4.05% of the Fund's net
assets as of December 31, 2004.

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Bond Fund (the Fund) is a separate fund of Oppenheimer Integrity
Funds, an open-end management investment company registered under the Investment
Company Act of 1940, as amended. During the reporting period, the Fund's
investment objective was to seek a high level of current income by investing
mainly in debt instruments. On January 14, 2005, shareholders of the Fund
approved a modification to the Fund's investment objective. Effective January
21, 2005, the Fund's investment objective is to seek total return by investing
mainly in debt instruments. Also effective January 21, 2005, the Fund changed
its name to Oppenheimer Core Bond Fund. 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 listed
or traded on National Stock Exchanges or other domestic or foreign 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.
Corporate, government and municipal debt instruments having a remaining maturity
in excess of 60 days and all mortgage-backed securities will be valued at the
mean between the "bid" and "asked" prices. Securities may be valued primarily
using dealer-supplied valuations or a portfolio pricing service authorized by
the Board of Trustees. Securities (including restricted securities) for which
market quotations are not readily available are valued

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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
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).

- --------------------------------------------------------------------------------
STRUCTURED NOTES. The Fund invests in structured notes whose market values,
interest rates and/or redemption prices are linked to the performance of
underlying foreign currencies, interest rate spreads, stock market indices,
prices of individual securities, commodities or other financial instruments or
the occurrence of other specific events. The structured notes are often
leveraged, increasing the volatility of each note's market value relative to the
change in the underlying linked financial element or event. Fluctuations in
value of these securities are recorded as unrealized gains and losses in the
accompanying financial statements. The Fund records a realized gain or loss when
a structured note is sold or matures. As of December 31, 2004, the market value
of these securities comprised 2.3% of the Fund's net assets and resulted in
unrealized cumulative losses of $43,500.

- --------------------------------------------------------------------------------
SECURITIES ON A WHEN-ISSUED BASIS OR FORWARD COMMITMENT. Delivery and payment
for securities that have been purchased by the Fund on a when-issued basis or
forward commitment can take place up to ten days or more after the trade date.
Normally the settlement date occurs within six months after the trade date;
however, the Fund may, from time to time, purchase securities whose settlement
date extends six months or more beyond trade date. During this period, such
securities do not earn interest, are subject to market fluctuation and may
increase or decrease in value prior to their delivery. The Fund maintains
internally designated assets with a market value equal to or greater than the
amount of its purchase commitments. The purchase of securities on a when-issued
basis or forward commitment may increase the volatility of the Fund's net asset
value to the extent the Fund executes such transactions while remaining
substantially fully invested. The Fund may also sell securities that it
purchased on a when-issued basis or forward commitment prior to settlement of
the original purchase. As of December 31, 2004, the Fund had purchased
$271,135,027 of securities on a when-issued basis or forward commitment and sold
$79,045,414 of securities issued on a when-issued basis or forward commitment.

      In connection with its ability to purchase or sell securities on a
when-issued basis, the Fund may enter into forward roll transactions with
respect to mortgage-related securities. Forward roll transactions require the
sale of securities for delivery in the current month, and a simultaneous
agreement with the same counterparty to repurchase similar (same type, coupon
and maturity) but not identical securities on a specified future date. The Fund
records the incremental difference between the forward purchase and sale of each
forward roll as realized gain (loss) on investments or as fee income in the case
of such


                         48 | OPPENHEIMER CORE BOND FUND



transactions that have an associated fee in lieu of a difference in the forward
purchase and sale price.

      Risks of entering into forward roll transactions include the potential
inability of the coun-terparty to meet the terms of the agreement; the potential
of the Fund to receive inferior securities at redelivery as compared to the
securities sold to the counterparty; counterparty credit risk; and the potential
pay down speed variance between the mortgage-related pools.

- --------------------------------------------------------------------------------
SECURITY CREDIT RISK. The Fund invests in high-yield securities, which may be
subject to a greater degree of credit risk, market fluctuations and loss of
income and principal, and may be more sensitive to economic conditions than
lower-yielding, higher-rated fixed-income securities. The Fund may acquire
securities in default, and is not obligated to dispose of securities whose
issuers subsequently default. As of December 31, 2004, securities with an
aggregate market value of $331,875, representing 0.05% of the Fund's net assets,
were in default.

- --------------------------------------------------------------------------------
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 December 31, 2004, the Fund had $2,007,359 of net capital loss
carryforward available to offset future realized capital gains, if any, and
thereby reduce future taxable gain distributions. As of December 31, 2004,
details of the capital loss carryforward were as follows:

2. During the fiscal year ended December 31, 2004, the Fund utilized $10,865,230
of capital loss carryforward to offset capital gains realized in that fiscal
year.

3. During the fiscal year ended December 31, 2003, the Fund utilized $21,308,857
of capital loss carryforward to offset capital gains realized in that fiscal
year.

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 December 31, 2004. Net assets of
the Fund were unaffected by the reclassifications.

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 December 31, 2004 are noted below. The primary
difference between book and tax appreciation or depreciation of securities and

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Board of Trustees has adopted a deferred
compensation plan for independent trustees that enables trustees to elect to
defer receipt of all or a portion of the annual compensation they are entitled
to receive from the Fund. For purposes of determining the amount owed to the
Trustee under the plan, deferred amounts are treated as though equal dollar
amounts had been invested in shares of the Fund or in other Oppenheimer funds
selected by the Trustee. The Fund purchases shares of the funds selected for
deferral by the Trustee in amounts equal to his or her deemed investment,
resulting in a Fund asset equal to the deferred compensation liability. Such
assets are included as a component of "Other" within the asset section of the
Statement of Assets and Liabilities. Deferral of trustees' fees under the plan
will not affect the net assets of the Fund, and will not materially affect the
Fund's assets, liabilities or net investment income per share. Amounts will be
deferred until distributed in accordance to the Plan.

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

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

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

- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. OppenheimerFunds Services (OFS), a division of the Manager,
acts as the transfer and shareholder servicing agent for the Fund. The Fund pays
OFS a per account fee. For the year ended December 31, 2004, the Fund paid
$1,672,747 to OFS for services to the Fund.

      Additionally, Class Y shares are subject to minimum fees of $10,000 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
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.

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued

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 up to 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 December 31,
2004 for Class B, Class C and Class N shares were $3,522,475, $1,649,652 and
$447,604, 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.

PAYMENTS AND WAIVERS OF EXPENSES. Effective March 1, 2004, the Manager has
voluntarily undertaken to limit the "Total Annual Operating Expenses" for all
classes of shares so that "Total Annual Operating Expenses," as percentages of
average daily net assets, will not exceed the following annual rates: 0.90% for
the Class A shares; 1.65% for the Class B and Class C shares, respectively;
1.15% for the Class N shares and 0.65% for the Class Y shares. During the year
ended December 31, 2004, the Manager reimbursed the Fund $595,195, $361,818,
$157,462 and $53,019 for Class A, Class B, Class C and Class N, respectively.
The Manager may terminate this voluntary expense limitation arrangement at any
time without notice to shareholders.

      OFS has voluntarily agreed to limit transfer and shareholder servicing
agent fees for all classes to 0.35% of average annual net assets per class.
During the year ended December 31, 2004, OFS waived $15,113 for Class N shares,
respectively. 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 December 31, 2004, the Fund had outstanding futures contracts as follows:



                                                                                    UNREALIZED

6. CREDIT SWAP CONTRACTS

The Fund may enter into a credit swap transaction to maintain a total return on
a particular investment or portion of its portfolio, or for other
non-speculative purposes. Because the principal amount is not exchanged, it
represents neither an asset nor a liability to either counterparty, and is
referred to as a notional principal amount. The Fund records an increase or
decrease to unrealized gain (loss), in the amount due to or owed by the Fund at
termination or settlement. Credit swaps are subject to credit risks (if the
counterparty fails to meet its obligations). The Fund pays an annual interest
fee on the notional amount in exchange for the counterparty paying in a
potential credit event.

During the year ended December 31, 2004, the Fund entered into transactions to
hedge credit risk. Information regarding the credit swaps is as follows:

7. TOTAL RETURN SWAP CONTRACTS

The Fund may enter into a total return swap transaction to maintain a total
return on a particular investment, or portion of its portfolio, or for other
non-speculative purposes. Because the principal amount is not exchanged, it
represents neither an asset nor a liability to either counterparty, and is
referred to as notional. The Fund records an increase or decrease to unrealized
gain (loss), in the amount due to or owed by the Fund at termination or
settlement. Total return swaps are subject to risks (if the counterparty fails
to meet its obligations).

As of December 31, 2004, the Fund had entered into the following total return
swap agreements:

8. ILLIQUID OR RESTRICTED SECURITIES

As of December 31, 2004, investments in securities included issues that are
illiquid or restricted. Restricted securities are purchased in private placement
transactions, are not registered under the Securities Act of 1933, may have
contractual restrictions on resale, and are valued under methods approved by the
Board of Trustees as reflecting fair value. A security may also 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 or restricted securities. Certain restricted securities, eligible for
resale to qualified institutional investors, are not subject to that limitation.
Information concerning restricted securities is as follows:

9. 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 US
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 also continues to receive
interest or dividends paid on the securities loaned. As of December 31, 2004,
the Fund had on loan securities valued at $94,771,672. Cash of $96,463,722 was
received as collateral for the loans, of which $47,027,357 was invested in
approved instruments.

10. LITIGATION

A consolidated amended complaint has been filed as putative derivative and class
actions against the Manager, OFS and the Distributor (collectively, the
"Oppenheimer defendants"), as well as 51 of the Oppenheimer funds (as "Nominal
Defendants") including the Fund, 31 present and former Directors or Trustees and
9 present and former officers of the funds. This complaint, filed in the U.S.
District Court for the Southern District of New York on January 10, 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

10. LITIGATION Continued

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 Oppenheimer defendants believe that the allegations contained in the
Complaints are without merit and that they, the funds named as Nominal
Defendants, and the Directors/Trustees of those funds have meritorious defenses
against the claims asserted. The Oppenheimer defendants intend to defend these
lawsuits vigorously and to contest any claimed liability, and they have retained
legal counsel to defend such suits. The Oppenheimer 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 CORE BOND FUND:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer Core Bond Fund, formerly known as Oppenheimer Bond Fund, a series of
Oppenheimer Integrity Funds, including the statement of investments, as of
December 31, 2004, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the two years in the
period then ended, and the financial highlights for the periods presented. 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.
An 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. Our procedures included confirmation of securities owned as of
December 31, 2004, by correspondence with the custodian and brokers; where
replies were not received from brokers, we performed other auditing procedures.
Additionally, an audit includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. 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 Core Bond Fund as of December 31, 2004, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for the
periods presented, in conformity with accounting principles generally accepted
in the United States of America.

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

- --------------------------------------------------------------------------------
In early 2005, if applicable, shareholders of record received information
regarding all dividends and distributions paid to them by the Fund during
calendar year 2004. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.

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

ITEM 9. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

      The registrant's Board of Trustees has established a Governance Committee,
one function of which is to create and oversee the process by which shareholders
can submit nominees for positions on the Board. The Governance Committee has not
yet adopted a charter, but anticipates that it will do so by the end of this
calendar year. The Committee has temporarily adopted the process previously
adopted by the Audit Committee regarding shareholder submission of nominees for
board positions. Shareholders may submit names of individuals, accompanied by
complete and properly supported resumes, for the Governance Committee's
consideration by mailing such information to the Committee in care of the Fund.
The Committee may consider such persons at such time as it meets to consider
possible nominees. The Committee, however, reserves solo discretion to determine
the candidates for trustees and independent trustees to recommend to the Board
and/or shareholders and may identify candidates other than those submitted by
Shareholders. The Committee may, but need not, consider the advice and
recommendation of the Manager and its affiliates in selecting nominees. The full
Board elects new trustees except for those instances when a shareholder vote is
required.

      Shareholders who desire to communicate with the Board should address
correspondence to the Board of Trustees of the registrant, or to an individual
Trustee c/o the Secretary of the Fund at 6803 South Tucson Way, Centennial,
Colorado 80112 and may submit their correspondence electronically at
WWW.OPPENHEIMERFUNDS.COM under the caption "contact us." If your correspondence
is intended for a particular Trustee, please indicate the name of the Trustee
for whom it is intended. The sender should indicate in the address whether it is
intended for the entire board, the Independent Trustees as group, or to an
individual Trustee. The Governance Committee will consider if a different
process should be recommended to the Board.
