Dear shareholder,
- --------------------------------------------------------------------------------

As we move further into 1998, we remain impressed by the strength of the U.S.
economy, despite the volatility in the world's financial markets. While we've
seen a decline in stock prices this summer, taking a wider perspective of the
markets reveals that, over the long term, U.S. and many world markets have
continued to serve investors well.

     At OppenheimerFunds, we are pleased to help our shareholders seek the
rewards of rising markets, but we also recognize that increasing levels of
return cannot last forever. In fact, we've already begun to see signs of change.
Because no one can predict exactly how the markets will react tomorrow or the
next day, we feel it is prudent to continually identify, evaluate and manage the
risks that may affect our fund shareholders.

     One of the leading risks facing investors today is rooted in the fact that
stock valuations remain at the high end of their historical range, while U.S.
corporate earnings growth is slowing. Given these circumstances, we believe,
regardless of daily fluctuations in the markets, it is unlikely that stocks will
sustain the unprecedented growth rate of the past three years. However, we also
believe that any market corrections we may see would be only temporary pauses on
the way to potential long-term gains.

     We are also examining the potential economic effects of the "millennium
problem" that will render many computer systems unable to recognize the year
2000 when it arrives. Solving this problem may require some companies to divert
substantial human and financial resources from their core businesses, possibly
constraining global economic growth during 1999 and 2000.

     For our part, we can report that OppenheimerFunds has made solid progress
toward ensuring that our shareholder accounting systems are fully "year 2000
compliant," and that all shareholder accounts will make a seamless transition
into the 21st century.

     We encourage you to meet with your financial advisor to discuss how today's
uncertain markets or the millennium problem may affect your investments.
Together, you can prepare your investment portfolio for the challenges and
opportunities of the new century.

Sincerely,


/s/ James C. Swain           /s/ Bridget A. Macaskill

Performance update
- --------------------------------------------------------------------------------

Oppenheimer Bond Fund performed well over the past six months, primarily because
of our allocation of assets to quality securities that provide relatively high
yields, including corporate bonds and commercial mortgage-backed securities. The
Fund's Class A shares also ranked in the top half of all A-rated corporate debt
funds for the six-month period ended 6/30/98, as measured by Lipper Analytical
Services, Inc./2/

3. Results of a hypothetical $10,000 investment in Class A shares on June 30,
1993. The Lehman Brothers Corporate Bond Index includes a broad range of
publicly issued nonconvertible investment-grade corporate debt of U.S. issuers,
widely recognized as a measure of the U.S. fixed-rate corporate bond market. It
is an unmanaged index including reinvestment of income, and cannot be purchased
directly by investors.
4. Pie chart is based on total market value of investments as of June 30,
1998 and is subject to change. Average credit quality and ratings allocations
include rated securities and those not rated by a national rating organization
(currently 6.6% of total investments) but to which ratings given above have been
assigned by the Manager for internal purposes as being comparable, in the
Manager's judgment, to securities rated by a rating agency in the same category.
Under normal market conditions, the Fund invests at least 65% of its assets in
investment grade securities. Securities rated below investment grade (up to 35%
of Fund's assets) carry a greater risk of default. While the Fund has generally
invested under 10% of its assets in foreign securities, which are subject to
exchange rate and political uncertainties, it is not restricted to any amount by
prospectus.
5. Portfolio is subject to change. Percentages are as of June 30, 1998 and are
based on net assets.

An interview with your Fund's manager
- --------------------------------------------------------------------------------

How has Oppenheimer Bond Fund performed over the past
six months?

The Fund's Class A shares provided a cumulative total return, without deducting
sales charges, of 3.81% for the six-month period ended June 30, 1998.(1)

Has the U.S. economy behaved as you expected so far in 1998?

When the year began, the economy was growing strongly. Yet, inflation was not a
problem, primarily because of higher productivity of U.S. companies and intense
competition from imported goods. At the time, we thought the U.S. economy would
slow during the first half of 1998 because of the Asian financial crisis, which
began in late 1997. We anticipated that weak demand for U.S. goods and services
from Asia would cause domestic growth to slow.

     That forecast has been partially true. Export growth has been quite weak
because of the Asian crisis. However, basic economic growth in the United States
has remained strong. American consumers appear to have picked up any slack
caused by weak demand from Asia. In fact, the U.S. employment rate is at its
highest levels in years, and Americans are borrowing and spending more than
previous decades on major purchases, such as cars, boats and second homes.

How did the U.S. bond market respond to that economic environment?

The various sectors of the bond market responded differently to the same
economic influences. High-yield corporate bonds, generally referred to as "junk
bonds," represented the top-performing sector of the bond market over the last
six months. Although junk bonds are subject to a greater risk of default, they
were in great demand by investors looking to maximize yields in a low
interest-rate environment.

     Despite some volatility early in the year, investment-grade corporate bonds
performed relatively well. A strong domestic economy held positive implications
for corporate earnings, so investors were confident regarding the credit quality
of most corporate bonds.

     Returns were almost as strong in U.S. Treasuries as long-term interest
rates declined modestly. However, prices of residential mortgage-backed
securities issued by U.S. government agencies were generally lower, providing
the weakest returns in the U.S. bond market.

     Commercial mortgage-backed securities, which are backed by mortgages on
commercial real estate, also provided attractive total returns. That's primarily
because the strong economy reduced the risk that commercial real estate owners
might fall behind in their mortgage payments.

"Strong economic growth and low inflation helped create an especially attractive
environment for high-yield corporate bonds."

An interview with your Fund's manager
- --------------------------------------------------------------------------------

Has the Fund's composition changed significantly over the past six months?

We've made a few modest changes in our allocations among the various bond market
sectors, increasing our holdings of longer maturity U.S. Treasuries. We also
slightly increased the Fund's exposure to corporate bonds and commercial
mortgage-backed securities to capture their relatively higher yields. At the
same time, we decreased our holdings of mortgage-backed securities issued by
U.S. government agencies. We also established a small position in bank trust
preferreds, which provided attractive yields and enjoyed high credit quality
relative to many other fixed-income securities.

What industries provided attractive opportunities within the corporate bond
sector? Which industries have you avoided? 

We continued to find competitive yields in corporate bonds issued by businesses
such as telecommunications, cable television and financial services companies,
which are enjoying the benefits of the strong economy. We also found attractive
opportunities in the transportation industry, particularly in railroads and
trucking.

     On the other hand, we tended to avoid bonds issued by utilities and basic
industries such as steel, chemicals and mining. The outlook for utilities is
uncertain because of deregulation, and basic industries, unable to raise prices
in a low-inflation environment, have suffered most from foreign price
competition.

"We believe that the economic impact of the Asian crisis is finally starting to
affect the U.S. economy..."


What's your outlook for the bond market over the rest of this year?

We think the U.S. bond market remains attractive. We believe that the Federal
Reserve Board will not tighten U.S. monetary policy because of the increasing
likelihood of an economic slowdown stemming from the recessions throughout Asia.
In fact, we believe that the economic impact of the Asian crisis is finally
starting to affect the U.S. economy, and will probably constrain economic growth
during the second half of this year.

     A neutral interest-rate policy, low inflation and slowing economic growth
could set the stage for long-term interest rates to decline further, which may
be especially good for U.S. Treasury bond prices. At the same time, we would
expect healthy investor demand to support prices of corporate bonds.

     Of course, we will continue to monitor the U.S. economy and bond market
carefully. Whatever the next six months bring, we intend to remain vigilant in
our efforts to deliver solid income potential from a broadly diversified
portfolio of quality securities.

1.   Face amount is reported in U.S. Dollars, except for those denoted in the
following currencies:

CAD--Canadian Dollar         XEU--European Currency Units 

2.   Identifies issues considered to be illiquid or restricted--See Note 8 of
Notes to Financial Statements.

3.   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.

4.   When-issued security to be delivered and settled after June 30, 1998.

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.

6.   Represents the current interest rate for a variable rate security.

7.   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 $22,221,768 or 7.27% of the Fund's net
assets as of June 30, 1998.

8.   Securities with an aggregate market value of $954,189 are held in
collateralized accounts to cover initial margin requirements on open futures
sales contracts. See Note 6 of Notes to Financial Statements.

9.   For zero coupon bonds, the interest rate shown is the effective yield on
the date of purchase.

10.  Units may be comprised of several components, such as debt and equity
and/or warrants to purchase equity at some point in the future. For units which
represent debt securities, face amount disclosed represents total underlying
principal.

11.  Denotes a step bond: a zero coupon bond that converts to a fixed or
variable interest rate at a designated future date.

12.  Interest or dividend is paid-in-kind.

13.  Non-income producing: issuer is in default of interest payment.

14.  Non-income producing security.

1. Significant Accounting Policies

Oppenheimer Bond Fund (the Fund) is a separate fund of Oppenheimer Integrity
Funds, a diversified, open-end management investment company registered under
the Investment Company Act of 1940, as amended. The Fund's investment objective
is to seek a high level of current income by investing mainly in debt
instruments. The Fund will, under normal market conditions, invest at least 65%
of its total assets in a diversified portfolio of investment grade debt
securities. The Fund's investment advisor is OppenheimerFunds, Inc. (the
Manager). The Fund offers Class A, Class B, Class C and Class Y shares. Class A
shares are sold with a front-end sales charge. Class B and Class C shares may be
subject to a contingent deferred sales charge. All classes of shares have
identical rights to earnings, assets and voting privileges, except that each
class has its own distribution and/or service plan, expenses directly
attributable to that class and exclusive voting rights with respect to matters
affecting that class. 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.

- --------------------------------------------------------------------------------
Investment Valuation. Portfolio securities are valued at the close of the New
York Stock Exchange on each trading day. Listed and unlisted securities for
which such information is regularly reported are valued at the last sale price
of the day or, in the absence of sales, at values based on the closing bid or
the last sale price on the prior trading day. Long-term and short-term
"non-money market" debt securities are valued by a portfolio pricing service
approved by the Board of Trustees. Such securities which cannot be valued by an
approved portfolio pricing service are valued using dealer-supplied valuations
provided the Manager is satisfied that the firm rendering the quotes is reliable
and that the quotes reflect current market value, or are valued under
consistently applied procedures established by the Board of Trustees to
determine fair value in good faith. Short-term "money market type" debt
securities having a remaining maturity of 60 days or less are valued at cost (or
last determined market value) adjusted for amortization to maturity of any
premium or discount. Forward foreign currency contracts are valued based on the
closing prices of the forward currency contract rates in the London foreign
exchange markets on a daily basis as provided by a reliable bank or dealer.
Options are valued based upon the last sale price on the principal exchange on
which the option is traded or, in the absence of any transactions that day, the
value is based upon the last sale price on the prior trading date if it is
within the spread between the closing bid and asked prices. If the last sale
price is outside the spread, the closing bid is used.

1.   Significant Accounting Policies (continued)

Securities Purchased on a When-Issued Basis. Delivery and payment for securities
that have been purchased by the Fund on a forward commitment or when-issued
basis can take place a month or more after the transaction 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, in a segregated account with its custodian, assets with a market
value equal to the amount of its purchase commitments. The purchase of
securities on a when-issued or forward commitment basis may increase the
volatility of the Fund's net asset value to the extent the Fund makes such
purchases while remaining substantially fully invested. As of June 30, 1998, the
Fund had entered into outstanding when-issued or forward commitments of
$37,755,887.

     In connection with its ability to purchase securities on a when-issued or
forward commitment basis, the Fund may enter into mortgage dollar-rolls in which
the Fund sells securities for delivery in the current month and simultaneously
contracts with the same counterparty to repurchase similar (same type coupon and
maturity) but not identical securities on a specified future date. The Fund
records each dollar-roll as a sale and a new purchase transaction.

- --------------------------------------------------------------------------------
Foreign Currency Translation. The accounting records of the Fund are maintained
in U.S. dollars. Prices of securities denominated in foreign currencies are
translated into U.S. dollars at the closing rates of exchange. Amounts related
to the purchase and sale of foreign securities and investment income are
translated at the rates of exchange prevailing on the respective dates of such
transactions.

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

- --------------------------------------------------------------------------------
Repurchase Agreements. The Fund requires the custodian to take possession, to
have legally segregated in the Federal Reserve Book Entry System or to have
segregated within the custodian's vault, all securities held as collateral for
repurchase agreements. The market value of the underlying securities is required
to be at least 102% of the resale price at the time of purchase. If the seller
of the agreement defaults and the value of the collateral declines, or if the
seller enters an insolvency proceeding, realization of the value of the
collateral by the Fund may be delayed or limited.

- --------------------------------------------------------------------------------
Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than
those attributable to a specific class) gains and losses are allocated daily 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.


                           36 Oppenheimer Bond Fund
<PAGE>
 
================================================================================

================================================================================


================================================================================
Federal Taxes. The Fund intends to continue to comply with provisions of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income, including any net realized gain on
investments not offset by loss carryovers, to shareholders. Therefore, no
federal income or excise tax provision is required.

- --------------------------------------------------------------------------------
Distributions to Shareholders. The Fund intends to declare dividends separately
for Class A, Class B, Class C and Class Y shares from net investment income each
day the New York Stock Exchange is open for business and pay such dividends
monthly. Distributions from net realized gains on investments, if any, will be
declared at least once each year.

- -------------------------------------------------------------------------------
Classification of Distributions to Shareholders. Net investment income (loss)
and net realized gain (loss) may differ for financial statement and tax purposes
primarily because of paydown gains and losses and the recognition of certain
foreign currency gains (losses) as ordinary income (loss) for tax purposes. The
character of the distributions made during the year from net investment income
or net realized gains may differ from its ultimate characterization for federal
income tax purposes. Also, due to timing of dividend distributions, the fiscal
year in which amounts are distributed may differ from the fiscal year in which
the income or realized gain was recorded by the Fund.

- --------------------------------------------------------------------------------
Other. Investment transactions are accounted for on the date the investments are
purchased or sold (trade date). Discount on securities purchased is amortized
over the life of the respective securities, in accordance with federal income
tax requirements. Realized gains and losses on investments and unrealized
appreciation and depreciation are determined on an identified cost basis, which
is the same basis used for federal income tax purposes.

     The preparation of financial statements in conformity with 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 revenues and expenses during the
reporting period. Actual results could differ from those estimates.

3.   Unrealized Gains and Losses on Investments

At June 30, 1998, net unrealized appreciation on investments of $9,491,641 was
composed of gross appreciation of $12,618,034, and gross depreciation of
$3,126,393.

================================================================================
4. Management Fees and Other Transactions with Affiliates

Management fees paid to the Manager were in accordance with the investment
advisory agreement with the Fund which provides for a fee of 0.75% of the first
$200 million of the Fund's average annual net assets, 0.72% of the next $200
million, 0.69% of the next $200 million, 0.66% of the next $200 million, 0.60%
of the next $200 million, and 0.50% of net assets in excess of $1 billion.

     For the six months ended June 30, 1998, commissions (sales charges paid by
investors) on sales of Class A shares totaled $317,678, of which $101,544 was
retained by OppenheimerFunds Distributor, Inc. (OFDI), a subsidiary of the
Manager, as general distributor, and by an affiliated broker/dealer. Sales
charges advanced to broker/dealers by OFDI on sales of the Fund's Class B shares
and C totaled $554,977 and $57,651, respectively, of which $38,164 and $2,287,
respectively, was paid to an affiliated broker/dealer. During the six months
ended June 30, 1998, OFDI received contingent deferred sales charges of $88,130
and $2,634, respectively, upon redemption of Class B and Class C shares as
reimbursement for sales commissions advanced by OFDI at the time of sale of such
shares.

     OppenheimerFunds Services (OFS), a division of the Manager, is the transfer
and shareholder servicing agent for the Fund and for other registered investment
companies. OFS's total costs of providing such services are allocated ratably to
these companies.

     The Fund has adopted a Service Plan for Class A shares to reimburse OFDI
for a portion of its costs incurred in connection with the personal service and
maintenance of shareholder accounts that hold Class A shares. Reimbursement is
made quarterly at an annual rate that may not exceed 0.25% of the average annual
net assets of Class A shares of the Fund. OFDI uses the service fee to reimburse
brokers, dealers, banks and other financial institutions quarterly for providing
personal service and maintenance of accounts of their customers that hold Class
A shares. During the six months ended June 30, 1998, OFDI paid $78,647 to an
affiliated broker/dealer as reimbursement for Class A personal service and
maintenance expenses.

4.   Management Fees and Other Transactions with Affiliates (continued)

The Fund has adopted Distribution and Service Plans for Class B and Class C
shares to compensate OFDI for its costs in distributing Class B and Class C
shares and servicing accounts. Under the Plans, the Fund pays OFDI an annual
asset-based sales charge of 0.75% per year on Class B and Class C shares for its
services rendered in distributing Class B and Class C shares. OFDI also receives
a service fee of 0.25% per year to compensate dealers for providing personal
services for accounts that hold Class B and Class C shares. Each fee is computed
on the average annual net assets of Class B and Class C shares, determined as of
the close of each regular business day. During the six months ended June 30,
1998, OFDI paid $3,094 to an affiliated broker/dealer as compensation for Class
B personal service and maintenance expenses and retained $226,996 and $38,082,
respectively, as compensation for Class B and Class C sales commissions and
service fee advances, as well as financing costs. If either Plan is terminated
by the Fund, the Board of Trustees may allow the Fund to continue payments of
the asset-based sales charge to OFDI for distributing shares before the Plan was
terminated. At June 30, 1998, OFDI had incurred unreimbursed expenses of
$1,683,303 for Class B and $198,844 for Class C.

================================================================================
5.   Forward Contracts

A forward foreign currency exchange contract (forward contract) is a commitment
to purchase or sell a foreign currency at a future date, at a negotiated rate.

     The Fund uses forward contracts to seek to manage foreign currency risks.
They may also be used to tactically shift portfolio currency risk. The Fund
generally enters into forward contracts as a hedge upon the purchase or sale of
a security denominated in a foreign currency. In addition, the Fund may enter
into such contracts as a hedge against changes in foreign currency exchange
rates on portfolio positions.

     Forward contracts are valued based on the closing prices of the forward
currency contract rates in the London foreign exchange markets on a daily basis
as provided by a reliable bank or dealer. The Fund will realize a gain or loss
upon the closing or settlement of the forward transaction.

     Securities held in designated accounts to cover net exposure on outstanding
forward contracts are noted in the Statement of Investments where applicable.
Unrealized appreciation or depreciation on forward contracts is reported in the
Statement of Assets and Liabilities. Realized gains and losses are reported with
all other foreign currency gains and losses in the Fund's Statement of
Operations.

     Risks include the potential inability of the counterparty to meet the terms
of the contract and unanticipated movements in the value of a foreign currency
relative to the U.S. dollar.

</TABLE>

================================================================================
6.   Futures Contracts

The Fund may buy and sell interest rate futures contracts in order to gain
exposure to or protect against changes in interest rates. The Fund may also buy
or write put or call options on these futures contracts.

     The Fund generally sells futures contracts to hedge against increases in
interest rates and the resulting negative effect on the value of fixed rate
portfolio securities. The Fund may also purchase futures contracts to gain
exposure to changes in interest rates as it may be more efficient or cost
effective than actually buying fixed income 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 expires.

     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 or
payable for the daily mark to market for variation margin.

     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.

At June 30, 1998, the Fund had outstanding futures contracts as follows:

================================================================================
7.   Illiquid and Restricted Securities

At June 30, 1998, investments in securities included issues that are illiquid or
restricted. Restricted securities are often 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 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 intends to invest no 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 limit. The aggregate value of illiquid or restricted securities
subject to this limitation at June 30, 1998 was $21,846,999, which represents
7.15% of the Fund's net assets.

================================================================================
8.   Acquisition of Oppenheimer LifeSpan Income Fund

On June 11, 1998, the Fund acquired all the net assets of Oppenheimer LifeSpan
Income Fund, pursuant to an agreement and plan of reorganization approved by the
Oppenheimer LifeSpan Income Fund shareholders on May 25, 1998. The Fund issued
2,793,467, 85,715 and 8,737 shares of beneficial interest for Class A, Class B
and Class C, respectively, valued at $30,889,321, $947,405 and $96,665 in
exchange for the net assets, resulting in combined Class A net assets of
$230,808,283, Class B net assets of $59,193,669 and Class C net assets of
$13,957,428 on June 12, 1998. The net assets acquired included net unrealized
appreciation of $514,326. The exchange qualified as a tax-free reorganization
for federal income tax purposes.

================================================================================
9.   Bank Borrowings

The Fund may borrow from a bank for temporary or emergency purposes including,
without limitation, funding of shareholder redemptions provided asset coverage
for borrowings exceeds 300%. The Fund has entered into an agreement which
enables it to participate with other Oppenheimer funds in an unsecured line of
credit with a bank, which permits borrowings up to $400 million, collectively.
Interest is charged to each fund, based on its borrowings, at a rate equal to
the Federal Funds Rate plus 0.35%. Borrowings are payable 30 days after such
loan is executed. The Fund also pays a commitment fee equal to its pro rata
share of the average unutilized amount of the credit facility at a rate of
0.0575% per annum. 

     The Fund had no borrowings outstanding during the six months ended June 30,
1998.
