DEAR SHAREHOLDER:

During one of the most challenging and volatile periods in the history of the
fixed income markets, Oppenheimer Multi-Sector Income Trust's (the Trust)
average annual total return at market value was 0.17%, and its dividend return
was 8.75% for the fiscal year ended October 31, 1998.1 Clearly, these results
are weaker than we would like. Nevertheless, we believe that the Trust's
disciplined strategy of sector diversification enabled us to help cushion the
impact of market volatility and limit some of the risks of investing during
exceptionally difficult times.

The Trust faced unique challenges and opportunities in three of its main
investment sectors: international, corporate and U.S. government. The challenges
stemmed from widespread economic difficulties in emerging markets, which
eventually affected developed markets as well. The trouble surfaced in Asia more
than a year ago, when an economic slowdown forced many Asian countries to
devalue their currencies. As a result, Asian companies that had borrowed heavily
to finance speculative business development incurred severe losses in foreign
exchange markets. When investors attempted to take their money out of the
region, securities prices plunged.

The global fixed income markets, especially among emerging countries, were
hardest hit by these events. While these markets generally offer the Trust its
greatest opportunities for high current income and capital appreciation, they
are also among the world's most volatile. In October 1997, as Asian markets and
currencies declined sharply, we sold many of our holdings in the region in an
attempt to preserve the Trust's capital. Although our actions caused us to
suffer some initial losses when these markets began to recover with unexpected
speed, we sought to take advantage of the opportunity, staking out significant
fixed income positions in the emerging markets of Latin America, Asia and
Eastern Europe at the end of November and in early December. From December 1997
through the end of April 1998, emerging markets were among the best performing
fixed income classes for the Trust.

However, in May 1998, deepening political and economic uncertainty caused
Russian markets to fall sharply. These events heightened investors' concerns
over the health of other emerging economies throughout the world. Latin American
markets and currencies came under selling pressure as investors turned to the
relative safety of the United 

Because of ongoing market volatility, the Trust's performance may be subject to
substantial short-term changes. For updates on the Trust's performance, please

1. Total return is based on changes in net asset value per share from 10/31/97
to 10/31/98, without deducting any sales charges or brokerage costs. Returns
would have been lower if sales charges were deducted. Dividend return is
determined by annualizing the October 1998 dividend of $0.067 and dividing by
the closing market price on the New York Stock Exchange of $9.19 per share on
10/23/98 (payment date). Past performance does not guarantee future results.

States. By the time emerging markets began to decline, we had worked to trim the
Trust's exposure to the international sector. However, this decline proved
deeper and more sustained than we anticipated. In August 1998, the decline
culminated in the worst month in the history of the emerging markets, resulting
in significant losses for the Trust.

At the same time, the market for high yield domestic corporate bonds also
suffered in the wake of the Asian crisis. Although the underlying U.S. economy
remained strong, with low inflation and low unemployment, profits declined among
multi-national companies because of weakening foreign demand. As profit growth
slowed, corporate stock and bond markets fell sharply in the United States. As a
result, from March 1998 through the end of the period, the Trust's high yield
investments yielded flat or negative returns every month. We helped limit our
losses in the corporate sector by focusing our holdings in telecommunications
bonds, which remained one of the strongest performing areas in the high yield
market. At the same time, with the exception of energy, we generally avoided
investments in companies that produce basic materials, such as chemicals, paper
and metals, all of which underperformed the market. We correctly foresaw that
the recent economic crisis in Asia would lead to excess production capacity and
weak pricing in these industries. We remained committed to the energy industry
in the belief that oil and natural gas represent tangible assets that we believe
are likely to retain their value over time. However, an unusually warm winter,
together with inaction on the part of the OPEC nations and slack global demand,
caused the Trust to suffer losses in these investments as well.

Partially offsetting the Trust's losses in the international and corporate
sectors were our investments in U.S. government securities. With low inflation,
low unemployment and relatively high rates of consumer spending, the U.S.
economy remained a bastion of strength in a time of global economic uncertainty.
Investors throughout the world searching for safe, high-quality securities
turned to long-term U.S. Treasury instruments for shelter. As a result,
long-term Treasuries performed quite well during the second half of the year. We
sought to take advantage of the opportunity by shifting some of the Trust's
assets from cash and mortgage-backed securities into Treasuries. We also acted
to lengthen the portfolio's average duration. Duration is a measure of a bond's
sensitivity to changes in interest rates. The longer a portfolio's average
duration, the higher the potential return investors may receive when interest
rates fall. In anticipation of continued low inflation, we extended the
portfolio's duration throughout the period, which enabled us to benefit from
falling interest rates and from the exceptional performance of longer-term
Treasuries.

It is impossible to predict exactly when the global economy will recover from
the effects of the current downturn. However, by placing each asset class in
which the Trust invests under the management of its own sector specialist, we
remain focused on our goals of returning high income to investors while working
to minimize the risks of each sector in which we invest. We believe our
disciplined strategy of sector diversification continues to make Oppenheimer
Multi-Sector Income Trust part of The Right Way to Invest.

Sincerely,

/s/ BRIDGET A. MACASKILL

2.  Securities with an aggregate market value of $10,775,010 are held in
    collateralized accounts to cover initial margin requirements on open futures
    sales contracts. See Note 6 of Notes to Financial Statements.

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

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

5.  Non-income producing security.

6.  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 $21,084,013 or 7.37% of the Trust's
    net assets as of October 31, 1998.

7.  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 underlying
    principal of the notes.

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

9.  Non-income producing -- issuer is in default.

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

11. Represents the current interest rate for an increasing rate security.

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

13. A sufficient amount of securities has been designated to cover outstanding
    forward foreign currency exchange contracts. See Note 5 of Notes to
    Financial Statements.

14. When-issued security to be delivered and settled after October 31, 1998.

15. 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.

16. 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.

NOTES TO FINANCIAL STATEMENTS
Oppenheimer Multi-Sector Income Trust

    1.  SIGNIFICANT ACCOUNTING POLICIES

    Oppenheimer Multi-Sector Income Trust (the Trust) is registered under the
    Investment Company Act of 1940, as amended, as a diversified, closed-end
    management investment company. The Trust's investment objective is to seek
    high current income consistent with preservation of capital. The Trust's
    investment advisor is OppenheimerFunds, Inc. (the Manager). The following is
    a summary of significant accounting policies consistently followed by the
    Trust.

    Investment Valuation -- Portfolio securities are valued at the close of the
    New York Stock Exchange on the last day of each week in which the New York
    Stock Exchange is open. 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
    the 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 exchange
    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.

    Structured Notes -- The Trust invests in foreign currency-linked structured
    notes whereby the market value and redemption price are linked to foreign
    currency exchange rates. The structured notes may be leveraged, which
    increases the notes' volatility relative to the face of the security.
    Fluctuations in values of the securities are recorded as unrealized gains
    and losses in the accompanying financial statements. During the year ended
    October 31, 1998, the market value of these securities comprised an average
    of 7% of the Trust's net assets, and resulted in realized and unrealized
    losses of $5,521,850.

    Securities Purchased on a When-Issued Basis -- Delivery and payment for
    securities that have been purchased by the Trust 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 Trust 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 Trust's net asset value to the extent the
    Trust makes such purchases while remaining substantially fully invested. As
    of October 31, 1998, the Trust had entered into outstanding when-issued or
    forward commitments of $2,775,250.



                                                                              25

NOTES TO FINANCIAL STATEMENTS (Continued)
Oppenheimer Multi-Sector Income Trust

    1.  SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    Securities Purchased on a When-Issued Basis (continued)
    In connection with its ability to purchase securities on a when-issued or
    forward commitment basis, the Trust may enter into mortgage dollar-rolls in
    which the Trust 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 Trust records each dollar-roll as a sale and a new purchase
    transaction.

    Security Credit Risk -- The Trust invests in high yield securities, which
    may be subject to a greater degree of credit risk, greater market
    fluctuations and risk of loss of income and principal, and may be more
    sensitive to economic conditions than lower-yielding, higher-rated fixed
    income securities. The Trust may acquire securities in default, and is not
    obligated to dispose of securities whose issuers subsequently default. As of
    October 31, 1998, securities with an aggregate market value of $236,227,
    representing 0.08% of the Trust's net assets, were in default.

    Foreign Currency Translation -- The accounting records of the Trust 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 Trust's Statement of Operations.

    Repurchase Agreements -- The Trust 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 Trust may be
    delayed or limited.

    Federal Taxes -- The Trust 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. As of October 31, 1998,
    the Trust had available for federal income tax purposes an unused capital
    loss carryover of approximately $9,493,000, which expires between 2003 to
    2006.

    Trustees' Fees and Expenses -- The Trust has adopted a nonfunded retirement
    plan for the Trust's independent trustees. Benefits are based on years of
    service and fees paid to each trustee during the years of service. During
    the year ended October 31, 1998, a provision of $33,369 was made for the
    Trust's projected benefit obligations and payments of $7,543 were made to
    retired trustees, resulting in an accumulated liability of $168,599 as of
    October 31, 1998.

    The Board of Trustees has adopted a deferred compensation plan for
    independent Trustees that enables a Trustee to elect to defer receipt of all
    or a portion of annual fees they are entitled to receive from the Trust.
    Under the plan, the compensation deferred by a Trustee is periodi-


26

NOTES TO FINANCIAL STATEMENTS (Continued)
Oppenheimer Multi-Sector Income Trust


    cally adjusted as though an equivalent amount had been invested in shares of
    one or more Oppenheimer funds selected by the Trustee. The amount paid to
    the Trustee under the plan will be determined based upon the performance of
    the selected funds. Deferral of Trustees' fees under the plan will not
    materially affect the Trust's assets, liabilities or net income per share.

    Distributions to Shareholders -- The Trust intends to declare and pay
    dividends from net investment income monthly. Distributions from net
    realized gains on investments, if any, will be made 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 Trust.

    The Trust 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
    $1,547,363, a decrease in overdistributed net investment income of
    $1,498,385, and a decrease in accumulated net realized loss on investments
    of $48,978.

    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. 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.
    Dividends-in-kind are recognized as income on the ex-dividend date, at the
    current market value of the underlying security. Interest on payment-in-kind
    debt instruments is accrued as income at the coupon rate and a market
    adjustment is made periodically.

    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.

    2. SHARES OF BENEFICIAL INTEREST

    The Trust has authorized an unlimited number of $.01 par value shares of
    beneficial interest. There were no transactions in shares of beneficial
    interest for the years ended October 31, 1998 and 1997.

    3. UNREALIZED GAINS AND LOSSES ON INVESTMENTS

    As of October 31, 1998, net unrealized depreciation on investments of
    $16,115,579 was composed of gross appreciation of $4,250,501, and gross
    depreciation of $20,366,080.



                                                                              27

Oppenheimer Multi-Sector Income Trust


    4. MANAGEMENT AND ADMINISTRATIVE FEES AND OTHER TRANSACTIONS WITH AFFILIATES

    Management fees paid to the Manager were in accordance with the investment
    advisory agreement with the Trust which provides for an annual fee of 0.65%
    on the Trust's average annual net assets.

    Mitchell Hutchins Asset Management Inc. serves as the Trust's Administrator.
    The Trust pays the Administrator an annual fee of 0.20% of the Trust's
    average annual net assets.

    The Manager acts as the accounting agent for the Trust at an annual fee of
    $24,000, plus out-of-pocket costs and expenses reasonably incurred.

    Shareholder Financial Services, Inc. (SFSI), a wholly-owned subsidiary of
    the Manager, is the transfer agent and registrar for the Trust. Fees paid to
    SFSI are based on the number of accounts and the number of shareholder
    transactions, plus out-of-pocket costs and expenses.

    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 Trust uses forward contracts to seek to manage foreign currency risks.
    They may also be used to tactically shift portfolio currency risk. The Trust
    generally enters into forward contracts as a hedge upon the purchase or sale
    of a security denominated in a foreign currency. In addition, the Trust 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 Trust will realize a
    gain or loss upon the closing or settlement of the forward transaction.

    Securities held in segregated 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
    Trust'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.

    As of October 31, 1998, the Trust had outstanding forward contracts as
    follows:

    6. FUTURES CONTRACTS

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

    The Trust 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 Trust 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 Trust 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 Trust 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 Trust 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
    and/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.

    As of October 31, 1998, the Trust had outstanding futures contracts as
    follows:

    7. OPTION ACTIVITY

    The Trust may buy and sell put and call options, or write put and covered
    call options on portfolio securities in order to produce incremental
    earnings or protect against changes in the value of portfolio securities.

    The Trust generally purchases put options or writes covered call options to
    hedge against adverse movements in the value of portfolio holdings. When an
    option is written, the Trust receives a premium and becomes obligated to
    sell or purchase the underlying security at a fixed price, upon exercise of
    the option.

    Options are valued daily based upon the last sale price on the principal
    exchange on which the option is traded and unrealized appreciation or
    depreciation is recorded. The Trust will realize a gain or loss upon the
    expiration or closing of the option transaction. When an option is
    exercised, the proceeds on sales for a written call option, the purchase
    cost for a written put option, or the cost of the security for a purchased
    put or call option is adjusted by the amount of premium received or paid.

    Securities designated to cover outstanding call options are noted in the
    Statement of Investments where applicable. Shares subject to

                                                                              29

    7. OPTION ACTIVITY (CONTINUED)

    call, expiration date, exercise price, premium received and market value are
    detailed in a footnote to the Statement of Investments. Options written are
    reported as a liability in the Statement of Assets and Liabilities. Gains
    and losses are reported in the Statement of Operations.

    The risk in writing a call option is that the Trust gives up the opportunity
    for profit if the market price of the security increases and the option is
    exercised. The risk in writing a put option is that the Trust may incur a
    loss if the market price of the security decreases and the option is
    exercised. The risk in buying an option is that the Trust pays a premium
    whether or not the option is exercised. The Trust also has the additional
    risk of not being able to enter into a closing transaction if a liquid
    secondary market does not exist.

    Written option activity for the year ended October 31, 1998 was as follows:

    8. 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 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 Trust 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 $17,825,807, which represents 6.23% of the Trust's net
    assets, of which $828,850 is considered restricted. Information concerning
    restricted securities is as follows:

INDEPENDENT AUDITORS' REPORT
Oppenheimer Multi-Sector Income Trust


The Board of Trustees and Shareholders of Oppenheimer Multi-Sector Income Trust:

We have audited the accompanying statements of investments and assets and
liabilities of Oppenheimer Multi-Sector Income Trust 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 five-year period then
ended. These financial statements and financial highlights are the
responsibility of the Trust'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 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 Multi-Sector Income Trust 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 five-year period then ended, in conformity with
generally accepted accounting principles.

FEDERAL INCOME TAX INFORMATION (Unaudited)
Oppenheimer Multi-Sector Income Trust


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

Dividends paid by the Trust during the fiscal year ended October 31, 1998 which
are not designated as capital gain distributions should be multiplied by 2.14%
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 Trust 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.



                                                                              33

OPPENHEIMER MULTI-SECTOR INCOME TRUST


    GENERAL INFORMATION CONCERNING THE TRUST

    Oppenheimer Multi-Sector Income Trust (the Trust) is a closed-end
    diversified management investment company with a primary investment
    objective of seeking high current income consistent with preservation of
    capital. The Trust's secondary investment objective is capital appreciation.
    In seeking its objectives, the Trust may invest any percentage of its assets
    in at least three of the following seven fixed-income sectors: U.S.
    Government, Corporate, International, Asset-Backed, Municipal, Convertible
    and Money Market. Current income, preservation of capital and, secondarily,
    possible capital appreciation may be considerations in the allocation of
    assets among such sectors. The Trust can invest in a number of different
    kinds of "derivative investments" and can also engage in certain special
    investment techniques, including repurchase transactions, when-issued and
    delayed delivery transactions and hedging. The Trust is not required to
    invest in any of these types of securities at all times. The investment
    advisor to the Trust is OppenheimerFunds, Inc. (the Manager).

    The Portfolio Managers of the Trust are Robert E. Patterson, Thomas P.
    Reedy, Ashwin K. Vasan, Carol E. Wolf and Arthur J. Zimmer and who also
    serve as Vice Presidents of the Trust and of the Manager, and are officers
    of certain mutual funds managed by the Manager (Oppenheimer funds). Messrs.
    Reedy and Vasan have been the persons principally responsible for the
    day-to-day management of the Trust's portfolio since June 1993. Prior to
    that Mr. Reedy served as a securities analyst for the Manager and Mr. Vasan
    served as a securities analyst for Citibank, N.A.

    Year 2000 Risks -- Because many computer software systems in use today
    cannot distinguish the year 2000 from the year 1900, the markets for
    securities in which the Trust invests could be detrimentally affected by
    computer failures beginning January 1, 2000. Failure of computer systems
    used for securities trading could result in settlement and liquidity
    problems for the Trust and other investors. That failure could have a
    negative impact on handling securities trades, pricing and accounting
    services. Data processing errors by government issuers of securities could
    result in economic uncertainties, and those issuers may incur substantial
    costs in attempting to prevent or fix such errors, all of which could have a
    negative effect on the Trust's investments and returns.

    The Manager and the Transfer Agent have been working on necessary changes to
    their computer systems to deal with the year 2000 and expect that their
    systems will be adapted in time for that event, although there cannot be
    assurance of success. Additionally, the services they provide depend on the
    interaction of their computer systems with those of brokers, information
    services, the Trust's Custodian and other parties. Therefore, any failure of
    the computer systems of those parties to deal with the year 2000 may also
    have a negative effect on the services they provide to the Trust. The extent

OPPENHEIMER MULTI-SECTOR INCOME TRUST
General Information Concerning the Trust (Continued)


    Dividend Reinvestment and Cash Purchase Plan -- Pursuant to the Trust's
    Dividend Reinvestment and Cash Purchase Plan (the Plan), as to shares of the
    Trust (Shares) not registered in nominee name, all dividends and capital
    gains distributions (Distributions) declared by the Trust will be
    automatically reinvested in additional full and fractional Shares unless a
    shareholder elects to receive cash. If Shares are registered in nominee
    name, the shareholder should consult the nominee if the shareholder desires
    to participate in the Plan. Shareholders that participate in the Plan
    (Participants) may, at their option, make additional cash investments in
    Shares, semi-annually in amounts of at least $100, through payment to
    Shareholder Financial Services, Inc., the agent for the Plan (the Agent),
    accompanied by a service fee of $0.75.

    Depending upon the circumstances hereinafter described, Plan Shares will be
    acquired by the Agent for the Participant's account through receipt of newly
    issued Shares or the purchase of outstanding Shares on the open market. If
    the market price of Shares on the relevant date (normally the payment date)
    equals or exceeds their net asset value, the Agent will ask the Trust for
    payment of the Distribution in additional Shares at the greater of the
    Trust's net asset value determined as of the date of purchase or 95% of the
    then-current market price. If the market price is lower than net asset
    value, the Distribution will be paid in cash, which the Agent will use to
    buy Shares on The New York Stock Exchange (the NYSE), or otherwise on the
    open market to the extent available. If the market price exceeds the net
    asset value before the Agent has completed its purchases, the average
    purchase price per Share paid by the Agent may exceed the net asset value,
    resulting in fewer Shares being acquired than if the Distribution had been
    paid in Shares issued by the Trust.

    Participants may elect to withdraw from the Plan at any time and thereby
    receive cash in lieu of Shares by sending appropriate written instructions
    to the Agent. Elections received by the Agent will be effective only if
    received more than ten days prior to the record date for any Distribution;
    otherwise, such termination will be effective shortly after the investment
    of such Distribution with respect to any subsequent Distribution. Upon
    withdrawal from or termination of the Plan, all Shares acquired under the
    Plan will remain in the Participant's account unless otherwise requested.
    For full Shares, the Participant may either: (1) receive without charge a
    share certificate for such Shares; or (2) request the Agent (after receipt
    by the Agent of signature guaranteed instructions by all registered owners)
    to sell the Shares acquired under the Plan and remit the proceeds less any
    brokerage commissions and a $2.50 service fee.

    Fractional Shares may either remain in the Participant's account or be
    reduced to cash by the Agent at the current market price with the proceeds
    remitted to the Participant. Shareholders who have previously withdrawn from
    the Plan may rejoin at any time by sending written instructions signed by
    all registered owners to the Agent.

    There is no direct charge for participation in the Plan; all fees of the
    Agent are paid by the Trust. There are no brokerage charges for Shares
    issued directly by the Trust. However, each Participant will pay a pro rata
    share of brokerage commissions incurred with respect to open market
    purchases of Shares to be issued under the Plan. Participants will receive
    tax information annually for their personal records and to assist in federal
    income tax return preparation. The automatic reinvestment of Distributions
    does not relieve Participants of any income tax that may be payable on
    Distributions.


                                                                              35
