In reviewing performance and rankings, please remember that past performance
does not guarantee future results. Investment return and principal value of an
investment in the Fund will fluctuate so that an investor's shares, when
redeemed, may be worth more or less than the original cost. Because of ongoing
market volatility, the Fund's performance may be subject to substantial
short-term changes. For updates on the Fund's performance, please contact your
financial advisor, call us at 1-800-525-7048 or visit our website,
www.oppenheimerfunds.com. Prior to March 1, 1996, the Fund had a different
investment advisor. However, the prior portfolio management team is now employed
by OppenheimerFunds, Inc., the current advisor.

Disciplined Value Fund

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

In retrospect, 1998 has been an unsettling year for the financial markets.
Around the world, stock and bond markets experienced considerable instability,
with particular tumult being felt in Southeast Asia, Russia and Latin America.
The U.S. stock market was not immune from the extreme volatility, as it climbed
to record levels through July before correcting sharply in the third quarter and
rebounding to new highs in the fourth quarter. In the bond market, yields on
U.S. Treasury securities declined to record lows before rising modestly late in
the year.

      Does the swift recovery of the U.S. stock market and the favorable
economic environment for the bond market mean that domestic stocks and bonds
will continue to prosper? We are optimistic over the long term, but we do expect
that concerns about corporate earnings growth in a slow-growth economy will
contribute to more stock market volatility in 1999. In the bond market, the
Federal Reserve Board's decisions to reduce short-term interest rates should
help create a positive climate for fixed income securities. While lower interest
rates are generally good for bond prices, it will become more difficult for bond
funds to maintain their dividends at current levels if yields decline further.

      As an Oppenheimer fund shareholder, you may wonder how this potential
volatility will affect you. If you maintain a long-term perspective, as we do,
short-term volatility over the coming months should have little bearing on your
ability to achieve your future financial goals. That's why we continue to
suggest that you adhere to your long-term investment plan. In fact, we are very
encouraged that most of our shareholders stayed the course during last summer's
stock market correction, avoiding the temptation of selling into a temporarily
declining market.

      Finally, I would like to thank those shareholders who contacted us about
our revised account statement. Response has been very positive, and we are
pleased that many of you find the new format easier to read and more
informative. If you have any questions about the new statement or any other
matter, please don't hesitate to call us at 1-800-525-7048. In the meantime,
thank you for choosing OppenheimerFunds, The Right Way to Invest.


Sincerely,

/s/ Bridget A. Macaskill

"Value stocks

long term..."

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

How did the Fund perform during the last twelve months?

The fiscal year that ended October 31, 1998, proved to be an exceptionally
difficult period for value stocks, especially the types of low price-to-earnings
multiple (P/E) stocks on which the Fund focuses. However, we believe that
underlying values in this sector are growing and that, in general, undervalued
stocks with positive earnings surprises are likely to reward investors for their
perseverance over time.

      The Fund's Class A shares earned an overall 4-star ranking ([4-star logo])
from Morningstar for the combined 3-, 5- and 10-year periods ended September 30,
1998, among 2,678 (3-year), 1,584 (5-year) and 713 (10-year) domestic equity
funds. /1/

What made this such a challenging period?

The trouble surfaced in Asia more than a year ago, when an economic slowdown
caused many Asian countries to devalue their currencies and emerging financial
markets to fall sharply. Concerns about the impact of reduced global spending on
corporate profits eventually affected the financial markets of developed nations
as well. We first saw the impact in the United States in late 1997, when the
stock markets experienced a brief, but sharp, decline. Stock performance
rebounded in early 1998 as investor concerns eased. However, the recovery proved
short-lived. Economic difficulties persisted in emerging markets throughout the
world. In the late spring, signs appeared that U.S. corporate profit growth was
suffering as a result of weakening global demand for a wide range of products.
Average stock prices fell as investors sought the safety of stocks of only the
largest and most visible companies.

Historically, value stocks have proven to be bargains over the long term, but
they have tended to underperform the market during times of slowing corporate
earnings growth and increasing investor uncertainty. Such an environment is
generally favorable for only the safest and most predictable investments, stocks
which are often characterized by relatively high P/E multiples.
Accordingly, despite the potential for positive earnings surprises, the Fund's
relatively low P/E stocks suffered this spring and summer.

How did you manage the Fund in light of these conditions?

We made a significant move away from companies that have a large exposure to
worldwide economic activity, especially to Asia. For example, we reduced our
holdings in companies that produce basic materials, such as metals, chemicals
and paper, because, as Asian companies reduce their manufacturing and exporting,
they also reduce their consumption of these materials. We sharply reduced our
holdings among financial institutions, many of which participated in loans to
Asian companies, and other Asian-based investments.

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

Instead, we focused the Fund's holdings among industries likely to perform well
even if the economy continues to slow, especially those with stable earnings and
improving management practices. For example, although stocks of domestic
retailers performed well for the Fund during the first half of the year, we
reduced the Fund's holdings of these and other consumer cyclicals later in the
period because we believe these companies' profits may suffer if discretionary
consumer spending slows. In their place, we made purchases among companies that
produce consumer staples in the food and beverage industries, because people
will continue to purchase these items regardless of the economic climate. We
also increased our holdings among utility companies such as Columbia Energy
Group and Bell Atlantic Corp.

      We took further advantage of the decline in stock prices during the summer
to add to our holdings of reasonably priced stocks that showed evidence of
improving fundamentals. The Fund found particular opportunities to purchase
technology stocks we believed were undervalued, such as Compaq Computer Corp.,
and International Business Machines Corp., and biotechnology and healthcare
stocks, such as Amgen, Inc. and Genzyme Corp. (General Division).


                      6 Oppenheimer Disciplined Value Fund

What is the outlook for your value management style in light of the market's
current uncertainties?

Historically, we have found that buying stocks with low P/E ratios--the value
approach--creates a portfolio that can outperform the stock market as a whole
over time. Our approach combines this value discipline with a growth strategy.
The growth component focuses on those low P/E stocks that also have positive
earnings surprises, because we believe that buying stocks in companies that are
doing better than people expected can add value over time.

      Since we developed this combined value and growth discipline in 1986, we
have been through several other difficult periods for value investing--
especially in 1990 and, to a lesser extent, in 1994. Despite these sub-par
periods, the Fund has produced good results for shareholders over time. Often,
after a period of underperformance, we have seen value-oriented stocks bounce
back with surprising strength and swiftness. This recovery can occur without
prior notice and with little opportunity for those not already invested in the
sector to share in the advance.

2. Total returns include changes in share price and reinvestment of dividends
and capital gains distributions in a hypothetical investment for the periods
shown. Class A returns include the current maximum initial sales charge of
5.75%. Class A shares were first publicly offered on 9/16/85. The Fund's maximum
sales charge for Class A shares was lower prior to 3/18/96, so actual
performance may have been higher. Class B returns include the applicable
contingent deferred sales charge of 5% (1-year) and 3% (since inception on
10/2/95). Class C returns for the one-year period include the contingent
deferred sales charge of 1%. Class C shares have an inception date of 5/1/96.
Class Y shares were first publicly offered on 12/16/96 and are not available for
sale to individual shareholders. Class B and C shares are subject to an annual
0.75% asset-based sales charge. An explanation of the different performance
calculations is contained in the Fund's prospectus.

It is impossible to predict exactly when the U.S. economy will recover from the
effects of the global downturn. But we believe that our disciplined strategy
continues to offer investors the potential to benefit from overlooked,
undervalued investment opportunities. That's why we believe that investors are
well served by holding the Fund even through difficult times, and why
Oppenheimer Disciplined Value Fund remains part of The Right Way to Invest.

Fund performance
- --------------------------------------------------------------------------------

How Has the Fund Performed? Below is a discussion, by the Manager, of the Fund's
performance during its fiscal year ended October 31,1998, followed by a
graphical comparison of the Fund's performance to an appropriate broad-based
market index.

      o Management's Discussion of Performance. During the past fiscal year that
ended October 31, 1998, Oppenheimer Disciplined Value Fund's performance was
affected by weakness in U.S. stock markets arising from pressures on earnings
and uncertainties regarding the Asian and emerging market financial crisis. We
responded by reducing the Fund's investments in sectors with significant
exposure to Asia. Instead we focused purchasing activity on defensive positions
in areas such as consumer staples and utilities. We also purchased undervalued
stocks in the technology and biotech industries. The Fund's portfolio holdings,
allocations and our management strategies are subject to change.

      o 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 October 31, 1998. In the case of Class A shares,
performance is measured over a 10-year period. In the case of Class B,
performance is measured from inception of the class on October 2, 1995. In the
case of Class C shares, performance is measured from inception of the class on
May 1, 1996. In the case of Class Y shares, performance is measured from
inception of the class on December 16, 1996. The Fund's performance reflects the
deduction of the 5.75% maximum initial sales charge on Class A shares, the 5%
(1-year) and 3% (since inception) applicable contingent deferred sales charge
for Class B, and the 1% (1-year) contingent deferred sales charge for Class C
shares. The graphs assume that all dividends and capital gains distributions
were reinvested in additional shares.

      The Fund's performance is compared to the performance of the Standard &
Poor's (S&P) 500 Index, a broad-based index of equity securities widely regarded
as a general measure of the performance of the U.S. equity securities market.
Index performance reflects the reinvestment of dividends but does not consider
the effect of capital gains or transaction costs, and none of the data in the
graphs shows the effect of taxes. The Fund's performance reflects the effects of
Fund 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 securities in the index.

================================================================================
1. Significant Accounting Policies

Oppenheimer Disciplined Value Fund (the Fund), a series of Oppenheimer Series
Fund, Inc. (the Company), is registered under the Investment Company Act of
1940, as amended, as a diversified, open-end management investment company. The
Fund's investment objective is to seek long term growth of capital by investing
primarily in common stocks with low price-earnings ratios and
better-than-anticipated earnings. Realization of current income is a secondary
consideration. 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 expenses directly attributable to that class and exclusive
voting rights with respect to matters affecting that class. Classes A, B and C
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.

- --------------------------------------------------------------------------------
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 Directors. 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 Directors 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.

- --------------------------------------------------------------------------------
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 is reported with all other foreign
currency gains and losses in the Fund's Statement of Operations.

================================================================================
1. Significant Accounting Policies (continued)

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.

- --------------------------------------------------------------------------------
Directors' Fees and Expenses. The Fund has adopted a nonfunded retirement plan
for the Fund's independent Directors. Benefits are based on years of service and
fees paid to each Director during the years of service. During the year ended
October 31, 1998, a provision of $8,429 was made for the Fund's projected
benefit obligations and payments of $3,017 were made to retired Directors,
resulting in an accumulated liability of $99,833 as of October 31, 1998.

            The Board of Directors has adopted a deferred compensation plan for
independent Directors that enables a Director to elect to defer receipt of all
or a portion of annual fees they are entitled to receive from the Fund. Under
the plan, the compensation deferred by a Director is periodically adjusted as
though an equivalent amount had been invested in shares of one or more
Oppenheimer funds selected by the Director. The amount paid to the Director
under the plan will be determined based upon the performance of the selected
funds. Deferral of Directors' fees under the plan will not materially affect the
Fund's assets, liabilities or net income per share.

- --------------------------------------------------------------------------------
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. Dividends and distributions to shareholders are
recorded on the ex-dividend date.


                      26 Oppenheimer Disciplined Value Fund
<PAGE>
 
- --------------------------------------------------------------------------------

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

Classification of Distributions to Shareholders. Net investment income (loss)
and net realized gain (loss) may differ for financial statement and 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.

            The Fund adjusts the classification of distributions to shareholders
to reflect the differences between financial statement amounts and distributions
determined in accordance with income tax regulations. Accordingly, during the
year ended October 31, 1998, amounts have been reclassified to reflect a
decrease in additional paid-in capital of $21,608, an increase in undistributed
net investment income of $14,185, and an increase in accumulated net realized
gain on investments of $7,423.

- --------------------------------------------------------------------------------
Other. Investment transactions are accounted for on the date the investments are
purchased or sold (trade date) and dividend income is recorded on the
ex-dividend date. 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 income and expenses during the reporting
period. Actual results could differ from those estimates.

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 0.625% of the first
$300 million of average annual net assets, 0.50% of the next $100 million and
0.45% of average annual net assets in excess of $400 million. The Manager acts
as the accounting agent for the Fund at an annual fee of $15,000, plus
out-of-pocket costs and expenses reasonably incurred. The Fund's management fee
for the year ended October 31, 1998 was 0.53% of the average annual net assets
for Class A, Class B, Class C and Class Y shares.

            For the year ended October 31, 1998, commissions (sales charges paid
by investors) on sales of Class A shares totaled $1,667,118, of which $789,178
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 and
Class C shares totaled $1,811,143 and $100,603, respectively, of which $435,243
and $9,638, respectively, was paid to an affiliated broker/dealer for Class B
and Class C shares. During the year ended October 31, 1998, OFDI received
contingent deferred sales charges of $202,849 and $10,623, 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 other Oppenheimer
funds. OFS's total costs of providing such services are allocated ratably to
these funds.

Notes to Financial Statements (Continued)
- --------------------------------------------------------------------------------

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

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 year ended October 31, 1998, OFDI paid $667,521 to an
affiliated broker/dealer as reimbursement for Class A personal service and
maintenance expenses.

            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 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 or Class C shares, determined as of the
close of each regular business day. During the year ended October 31, 1998, OFDI
paid $42,263 and $12,392, respectively, to an affiliated broker/dealer as
compensation for Class B and Class C personal service and maintenance expenses
and retained $933,605 and $110,797, 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 Directors may
allow the Fund to continue payments of the asset-based sales charge to OFDI for
distributing shares before the Plan was terminated. As of October 31, 1998, OFDI
had incurred excess distribution and servicing costs of $3,212,917 for Class B
and $219,766 for Class C.

================================================================================
5. Illiquid and Restricted Securities

As of October 31, 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 Directors 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 as of October 31, 1998, was $95,299, which represents
0.01% of the Fund's net assets.

6. 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 year ended October
31, 1998.

Oppenheimer Value Stock Fund, pursuant to an agreement and plan of
reorganization approved by the Oppenheimer Value Stock Fund shareholders on July

stock for Class A, Class B and Class C, respectively, valued at $178,988,994,

Independent Auditors' Report
- --------------------------------------------------------------------------------

================================================================================
The Board of Directors and Shareholders of
Oppenheimer Disciplined Value Fund:

We have audited the accompanying statements of investments and assets and
liabilities of Oppenheimer Disciplined Value Fund as of October 31, 1998, and
the related statement of operations for the year then ended, the statements of
changes in net assets for each of the years in the two-year period then ended
and the financial highlights for each of the years in the two-year period then
ended and the ten months ended October 31, 1996. 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. The financial highlights for each of
the years in the three-year period ended December 31, 1995, were audited by
other auditors whose report dated February 9, 1996, expressed an unqualified
opinion on this information.

            We conducted our audits in accordance with generally accepted
auditing standards. 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
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of October 31, 1998 by correspondence with the custodian and brokers;
and where confirmations were not received from brokers, we performed other
auditing procedures. An audit also 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 Disciplined Value Fund as of October 31, 1998, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the two-year period then ended, and the financial
highlights for each of the years in the two-year period then ended October 31,
1998, and the ten months ended October 31, 1996, in conformity with generally
accepted accounting principles.

Federal Income Tax Information (Unaudited)
- --------------------------------------------------------------------------------

In early 1999 shareholders will receive information regarding all dividends and
distributions paid to them by the Fund during calendar year 1998. Regulations of
the U.S. Treasury Department require the Fund to report this information to the
Internal Revenue Service.

            Distributions of $2.8713, $2.7976, $2.7751 and $2.9216 per share
were paid to Class A, Class B, Class C and Class Y shareholders, respectively,
on December 16, 1997, of which, for each class of shares, $0.6518 was designated
as a capital gain distribution in the "28% Rate Group" and $1.4327 was
designated as a capital gain distribution in the "20% Rate Group" for federal
income tax purposes. Whether received in stock or cash, the capital gain
distribution should be treated by shareholders as a gain from the sale of
capital assets.

            Dividends paid by the Fund during the year ended October 31, 1998,
which are not designated as capital gain distributions should be multiplied by
100.00% to arrive at the net amount eligible for the corporate dividend-received
deduction.

            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.
