Expenses

   
The Fund pays a variety of  expenses  directly  for  management  of its  assets,
administration,  distribution  of its  shares  and  other  services,  and  those
expenses are subtracted from the Fund's assets to calculate the Fund's net asset
value per share.  All  shareholders  therefore  pay those  expenses  indirectly.
Shareholders  pay other  expenses  directly,  such as sales  charges and account
transaction  charges.  The following  tables are provided to help you understand
your  direct  expenses  of  investing  in the Fund and your  share of the Fund's
operating expenses that you will bear indirectly. The numbers below are based on
the Fund's expenses during its last fiscal year ended September 30, 1997.

      o  Shareholder  Transaction  Expenses  are charges you pay when you buy or
sell shares of the Fund. Please refer to "About Your Account,"  starting on page
__, for an explanation of how and when
    
these charges apply.

1. If you  invest $1  million  or more in Class A shares,  you may have to pay a
sales charge of up to 1% if you sell your shares  within 12 calendar  months (18
months for shares  purchased  prior to May 1, 1997) from the end of the calendar
month in which you  purchased  those  shares.  See "How to Buy  Shares - Class A
Shares,"  below.  2. See "How to Buy Shares - Buying Class B Shares" and "How to
Buy  Shares  -  Buying  Class C  Shares,"  below  for  more  information  on the
contingent  deferred  sales  charges.  3.  There  is a $10  transaction  fee for
redemptions paid by Federal Funds wire, but not for redemptions paid by check or
by ACH wire transfer through AccountLink,  or for which checkwriting  privileges
are used (see "How To Sell Shares").

      o Annual Fund  Operating  Expenses  are paid out of the Fund's  assets and
represent the Fund's expenses in operating its business.  For example,  the Fund
pays management fees to its investment advisor, OppenheimerFunds, Inc. (referred
to in this Prospectus as the "Manager"). The rates of the Manager's fees are set
forth in "How the Fund is Managed,"  below.  The Fund has other regular expenses
for services,  such as transfer agent fees, custodial fees paid to the bank that
holds the Fund's  portfolio  securities,  audit fees and legal  expenses.  Those
expenses are detailed in the Fund's  Financial  Statements  in the  Statement of
Additional Information.

  Expenses

   
      The numbers in the chart  above are based upon the Fund's  expenses in its
last  fiscal  year  ended  September  30,  1997.  These  amounts  are shown as a
percentage of the average net assets of each class of the Fund's shares for that
year.  The 12b-1 Plan Fees for Class A shares are Service Plan Fees. For Class B
and for  Class C shares  the  12b-1  Plan  Fees are the  Service  Plan  Fees and
asset-based  sales charge.  The service fee for each class is a maximum of 0.25%
of average  annual net assets of the class and the  asset-based  sales charge is
0.75%. These plans are described in greater detail in "How to Buy Shares" below.
    

      The actual  expenses  for each class of shares in future years may be more
or less  than the  numbers  in the  chart,  depending  on a number  of  factors,
including  changes in the actual value of the Fund's assets  represented by each
class of shares.

   
      o Examples.  To try to show the effect of these  expenses on an investment
over time, we have created the  hypothetical  examples shown below.  Assume that
you make a $1,000  investment in each class of shares of the Fund,  and that the
Fund's annual  return is 5%, and that its operating  expenses for each class are
the ones shown in the Annual Fund Operating Expenses table above. If you were to
redeem your shares at the end of each period shown below,  your investment would
incur the following expenses by the end of 1, 3, 5 and 10 years:
    

                     1 year    3 years      5 years     10
years(1)
- -------------------------------------------------------------------
Class A Shares       $45       $66          $ 89        $155
- -------------------------------------------------------------------
   
Class B Shares       $58       $77          $107        $173
    
- -------------------------------------------------------------------
   
Class C Shares       $28       $56          $ 96        $208
    

      If you did not  redeem  your  investment,  it would  incur  the  following
expenses:

Class A Shares       $45       $66          $89         $155
- -------------------------------------------------------------------
   
Class B Shares       $18       $56          $97         $172
    
- -------------------------------------------------------------------
   
Class C Shares       $18       $56          $96         $208

1. In the first example,  expenses  include the Class A initial sales charge and
the  applicable  Class B or Class C contingent  deferred  sales  charge.  In the
second example,  Class A expenses include the initial sales charge,  but Class B
and Class C expenses do not include contingent deferred sales charges. The Class
B expenses in years 7 through 10 are based on the Class A expenses  shown above,
because the Fund automatically  converts your Class B shares into Class A shares
after 6 years.  Because of the effect of the  asset-based  sales  charge and the
contingent  deferred  sales  charge  imposed  on  Class B and  Class  C  shares,
long-term  holders  of  Class  B and  Class C  shares  could  pay  the  economic
equivalent  of more  than the  maximum  front-end  sales  charge  allowed  under
applicable  regulations.  For Class B shareholders,  the automatic conversion of
Class B shares to Class A shares is  designed to minimize  the  likelihood  that
this will occur. Please refer to "How to Buy Shares - Buying Class B Shares" for
more information.

      These examples show the effect of expenses on an  investment,  but are not
meant to state or predict actual or expected costs or investment  returns of the
Fund, all of which may be more or less than those shown below.
    


A Brief Overview of the Fund

      Some of the  important  facts about the Fund are  summarized  below,  with
references to the section of this Prospectus where more complete information can
be found.  You should  carefully  read the  entire  Prospectus  before  making a
decision about  investing in the Fund.  Keep the Prospectus for reference  after
you invest, particularly for information about your account, such as how to sell
or exchange shares.

     o What Is The Fund's Investment Objective?  The Fund's investment objective
is to seek a high level of current income exempt from Federal income tax.

      o What Does the Fund  Invest  In? To seek its  objective,  the Fund  will,
under  normal  market  conditions,   invest  at  least  80%  of  its  assets  in
investment-grade Municipal Securities. The Fund may also use hedging instruments
and  some  derivative  investments  to try to  manage  investment  risks.  These
investments  and their risks are more fully  explained in "Investment  Objective
and Policies," starting on page __.

   
      o Who Manages the Fund? The Fund's  investment  advisor (the "Manager") is
OppenheimerFunds,  Inc. The Manager (including  subsidiaries) advises investment
company  portfolios  having over $75 billion in assets as of December  31, 1997.
The Manager is paid an advisory  fee by the Fund,  based on its net assets.  The
Fund's  portfolio  manager,  who is employed  by the  Manager  and is  primarily
responsible for the selection of the Fund's securities,  is Caryn Halbrecht. The
Fund's  Board of Trustees,  elected by  shareholders,  oversees  the  investment
advisor and the  portfolio  manager.  Please refer to "How the Fund is Managed,"
starting on page __ for more information about the Manager and its fees.
    

      o How Risky is the Fund? All investments  carry risks to some degree.  The
Fund's investments in Municipal Securities are subject to changes in their value
from a number of factors such as changes in general bond market  movements,  the
change in value of  particular  securities  because  of an event  affecting  the
issuer,  or changes in interest  rates.  These  changes  affect the value of the
Fund's  investments and its price per share. In the  OppenheimerFunds  spectrum,
the Fund is generally  more  conservative  than high yield bond funds,  but more
risky  than money  market  funds.  While the  Manager  tries to reduce  risks by
diversifying  investments,  by carefully researching  securities before they are
purchased  for the  portfolio,  and in some cases by using  hedging  techniques,
there is no  guarantee of success in achieving  the Fund's  objectives  and your
shares may be worth more or less than their  original cost when you redeem them.
Please  refer  to  Investment  Risks"  starting  on page __ for a more  complete
discussion.

      o How Can I Buy Shares?  You can buy shares  through your broker or dealer
or  financial  institution,  or you can  purchase  shares  directly  through the
Distributor  by completing an  Application  or by using an Automatic  Investment
Plan under AccountLink.  Please refer to "How To Buy Shares" starting on page __
for more details.

      o Will I Pay a Sales Charge to Buy Shares?  The Fund has three  classes of
shares.  All three  classes have the same  investment  portfolio  but  different
expenses.  Class A shares are offered with a front-end sales charge, starting at
3.50%, and reduced for larger  purchases.  Class B shares and Class C shares are
offered  without a front-end  sales  charge,  but may be subject to a contingent
deferred  sales  charge if  redeemed  within 5 years or 12  months of  purchase,
respectively.  There are also annual  asset-based  sales  charges on Class B and
Class C shares.  Please review "How To Buy Shares"  starting on page __ for more
details,  including a discussion  about factors you and your  financial  adviser
should consider in determining which class may be appropriate for you.

      o How Can I Sell My Shares? Shares can be redeemed by mail or by telephone
call to the Transfer  Agent on any business day,  through your broker or dealer,
or by writing a check  against your Fund account  (available  for Class A shares
only).  Please refer to "How To Sell Shares"  starting on page __. The Fund also
offers  exchange  privileges to other  Oppenheimer  funds,  described in "How to
Exchange Shares" starting on page __.

      o How Has the Fund Performed? The Fund measures its performance by quoting
its yield,  tax  equivalent  yield,  average  annual total return and cumulative
total return, which measure historical performance. Those returns and yields can
be compared to the yields and returns (over similar  periods) of other funds. Of
course,  other  mutual funds may have  different  objectives,  investments,  and
levels of risk.  The Fund's  performance  can also be compared to a broad market
index,  which  we have  done on  pages  __ and __.  Please  remember  that  past
performance does not guarantee future results.

Investment Objective and Policies

Objective.   The  Fund's  investment  objective  is  to  provide  a
high level of current income exempt from Federal income tax.

Investment Policies and Strategies.  The Fund will seek to attain its investment
objective by  investing,  under normal  market  conditions,  at least 80% of its
total  assets  in  a  portfolio  of  "investment-grade"   Municipal  Securities.
"Investment-grade"  are those rated - or are  determined by the Manager to be of
comparable quality to those rated - within the four highest rating categories of
Moody's Investors Service, Inc., Standard & Poor's Corporation,  Fitch Investors
Service, Inc. or another rating organization. Municipal Securities in the fourth
highest rating category (for example,  municipal bonds rated "Baa" and municipal
notes rated "MIG 2" by Moody's,  and  municipal  bonds rated "BBB" and municipal
notes rated "SP-2" by Standard & Poor's),  although of investment  grade, may be
subject to greater market fluctuations and risks of loss of income and principal
than  higher-rated   Municipal  Securities,   and  may  be  considered  to  have
speculative characteristics.  Although unrated securities are not necessarily of
lower quality,  the market for them may not be as broad as for rated securities.
A reduction  in the rating of a security  after it is purchased by the Fund will
not require its  disposition.  To the extent that the Fund holds securities that
have fallen  below  investment  grade,  there is a greater  risk that the Fund's
receipt of interest income and principal will be impaired and that its net asset
value will be  affected  if the  issuers of such  securities  fail to meet their
obligations.  See Appendix A to the  Statement of Additional  Information  for a
description of the various rating categories.

      Under  normal  market  conditions,  no more than 20% of the  Fund's  total
assets will be invested in taxable investments. However, for temporary defensive
purposes,  the  Fund  may  invest  up to 100% of its  total  assets  in  taxable
certificates  of deposit and  commercial  paper and taxable or tax-exempt  money
market   instruments.   The  Fund  may  purchase   Municipal   Securities  on  a
"when-issued" basis and may purchase or sell Municipal  Securities on a "delayed
delivery"  basis.  Under  normal  market  conditions,  the Fund will  maintain a
dollar-weighted average portfolio maturity of more than three years but not more
than ten years. In calculating maturity, the Fund will consider various factors,
including  anticipated payments of principal.  The Fund may hold securities with
maturities of more than ten years  provided that under normal  circumstances  it
maintains a dollar-weighted average portfolio maturity as stated above.

     o Can the Fund's Investment  Objective and Policies Change? The Fund has an
investment objective, described above, as well as investment policies it follows
to try to achieve its objective.  Additionally, the Fund uses certain investment
techniques and strategies in carrying out those investment policies.  The Fund's
investment policies and techniques are not "fundamental"  unless this Prospectus
or the  Statement of  Additional  Information  says that a particular  policy is
"fundamental." The Fund's investment objective is a fundamental policy.

      Fundamental policies are those that cannot be changed without the approval
of a "majority" of the Fund's  outstanding voting shares. The term "majority" is
defined  in  the  Investment  Company  Act  to  be a  particular  percentage  of
outstanding  voting  shares  (and this term is  explained  in the  Statement  of
Additional Information). The Fund's Board of Trustees may change non-fundamental
policies without  shareholder  approval,  although  significant  changes will be
described in amendments to this Prospectus.

   
      o Portfolio Turnover. A change in the securities held by the Fund is known
as "portfolio  turnover."  The Fund  generally will not engage in the trading of
securities for the purpose of realizing  short-term gains, but the Fund may sell
securities as the Manager deems advisable to take advantage of  differentials in
yield to seek to accomplish  the Fund's  investment  objective.  The  "Financial
Highlights"  above show the Fund's  portfolio  turnover  rate during past fiscal
years. While short-term trading increases portfolio  turnover,  and may increase
the Fund's transaction costs, the Fund incurs little or no brokerage costs.
    

Investment Risks

      All  investments  carry risks to some degree,  whether they are risks that
market prices of the investment  will fluctuate (this is known as "market risk")
or that the underlying  issuer will experience  financial  difficulties  and may
default on its obligation  under a  fixed-income  investment to pay interest and
repay principal (this is referred to as "credit risk"). These general investment
risks,  and the special risks of certain types of investments  that the Fund may
hold are described below. They affect the value of the Fund's  investments,  its
investment  performance,  and the prices of its shares. These risks collectively
form the risk profile of the Fund.

      Because of the types of securities  the Fund invests in and the investment
techniques  the Fund uses,  the Fund is designed for investors who are investing
for the long term.  It is not intended for  investors  seeking  assured  income.
While  the  Manager  tries to  reduce  risks  by  diversifying  investments,  by
carefully researching securities before they are purchased, and in some cases by
using  hedging  techniques,  changes in overall  market  prices can occur at any
time, and because the income earned on securities is subject to change, there is
no  assurance  that the Fund will  achieve its  investment  objective.  When you
redeem your shares, they may be worth more or less than what you paid for them.

      o Interest Rate Risk.  The values of Municipal  Securities  will vary as a
result of changing  evaluations by rating  services and investors of the ability
of the issuers of such securities to meet their principal and interest payments.
Such values will also  change in response to changes in interest  rates:  should
interest  rates  rise,  the  values of  outstanding  Municipal  Securities  will
probably  decline  and  (if  purchased  at  principal  amount)  would  sell at a
discount;  should  interest  rates  fall,  the values of  outstanding  Municipal
Securities will probably  increase and (if purchased at principal  amount) would
sell at a premium.  Changes  in the value of  Municipal  Securities  held in the
Fund's  portfolio  arising from these or other factors will not affect  interest
income derived from those  securities but will affect the Fund's net asset value
per share.

      Generally,  securities of longer  maturities  are subject to greater price
fluctuations due to changes in interest rates.  There are no restrictions on the
maturities  of the Municipal  Securities in which the Fund may invest.  The Fund
will  seek to  invest in  Municipal  Securities  that,  in the  judgment  of the
Manager,  will provide a high level of current income consistent with the Fund's
liquidity requirements and conditions affecting the Municipal Securities market.

   
      o There are special  risks in investing  in  derivative  investments.  The
risks of investing in derivative investments include not only the ability of the
issuer of the derivative investment to pay the amount due on the maturity of the
investment,  but also the risk that the  underlying  investment  or  security on
which the derivative is based,  and the derivative  itself,  may not perform the
way the Manager expected it to perform. That can mean that the Fund will realize
less income than  expected or that it can lose part of its  investment.  Another
risk of investing in derivative  investments is that their market value could be
expected to vary to a much  greater  extent than the market  value of  municipal
securities that are not derivative  investments but have similar credit quality,
redemption provisions and maturities. These risks affect the price of the Fund's
shares.
    

      o Hedging instruments can be volatile  investments and may involve special
risks.  If the  Manager  uses a hedging  instrument  at the wrong time or judges
market conditions incorrectly,  hedging strategies may reduce the Fund's return.
The Fund could also  experience  losses if the prices of its futures and options
positions  were not  correlated  with its other  investments  or if it could not
close out a position because of an illiquid market for the future or option.

      Options  trading  involves  the  payment of  premiums  and has special tax
effects  on the  Fund.  There  are  also  special  risks in  particular  hedging
strategies.  For example,  in writing puts, there is a risk that the Fund may be
required to buy the underlying security at a disadvantageous  price. These risks
and the hedging  strategies  the Fund may use are described in greater detail in
the Statement of Additional Information.

Investment Techniques and Strategies

      The Fund may also use the investment  techniques and strategies  described
below,  which involve  certain  risks.  The Statement of Additional  Information
contains more information about these practices,  including limitations on their
use that are designed
to reduce some of the risks.

      o  Municipal  Securities.  "Municipal  Securities"  are  municipal  bonds,
municipal  notes, tax  anticipation  notes,  bond  anticipation  notes,  revenue
anticipation  notes,   construction  loan  notes  and  other  short-term  loans,
tax-exempt commercial paper and other debt obligations issued by or on behalf of
states, the District of Columbia, any commonwealths,  territories or possessions
of the United States,  or their  respective  political  subdivisions,  agencies,
instrumentalities  or  authorities,  the  interest  from which is not subject to
Federal  individual  income tax in the opinion of bond counsel to the respective
issuer at the time of issue. No independent  investigation  has been made by the
Manager as to the users of proceeds of bond offerings or the application of such
proceeds.

      The two principal  classifications  of Municipal  Securities  are "general
obligations"  (secured  by the  issuer's  pledge of its full  faith,  credit and
taxing  power  for  the  payment  of  principal   and   interest)  and  "revenue
obligations"  (payable only from the revenues derived from a particular facility
or class of facilities,  or a specific excise tax or other revenue source).  The
Fund may invest in  Municipal  Securities  of both  classifications,  subject to
particular restrictions described below.

      Yields on  Municipal  Securities  vary  depending on a variety of factors,
including the general  condition of the  financial  markets and of the Municipal
Securities market in particular, the size of a particular offering, the maturity
of the  security  and the  credit  rating of the  issuer.  Generally,  Municipal
Securities of longer maturities produce higher current yields but are subject to
greater price  fluctuation due to changes in interest rates  (discussed  above),
tax laws and other general  market  factors than are Municipal  Securities  with
shorter  maturities.  Similarly,  lower- rated  Municipal  Securities  generally
produce a greater yield than higher-rated  Municipal Securities due to a concern
that there is a greater  degree of risk as to the  ability of the issuer to meet
principal and interest  obligations.  "Investment Objective and Policies" in the
Statement of Additional  Information  contains more information  about Municipal
Securities.

      o Investments  in Taxable  Securities and Temporary  Defensive  Investment
Strategy.  Under normal market conditions,  the Fund may invest up to 20% of its
assets in taxable  investments,  including (i) certain  "Temporary  Investments"
(described  in the next  paragraph);  (ii)  hedging  instruments  (described  in
"Hedging" below); (iii) repurchase agreements (explained below).

      In times of  unstable  economic  or market  conditions,  the  Manager  may
determine that it is appropriate for the Fund to assume a temporary  "defensive"
position  by  investing  some or all of its  assets  (there  is no  limit on the
amount) in  short-term  money  market  instruments.  These  include  the taxable
obligations  described above,  U.S.  government  securities,  bank  obligations,
commercial paper,  corporate  obligations and other instruments  approved by the
Fund's Board of  Trustees.  This  strategy  would be  implemented  to attempt to
reduce  fluctuations  in the  value  of the  Fund's  assets.  The  Fund may hold
temporary  investments  pending the investment of proceeds from the sale of Fund
shares or portfolio  securities,  pending  settlement  of purchases of Municipal
Securities, or to meet anticipated redemptions. To the extent the Fund assumes a
temporary  defensive  position,  a portion  of the Fund's  distributions  may be
subject to  Federal  and state  income  taxes and the Fund may not  achieve  its
objective.

      o Municipal  Lease  Obligations.  The Fund may invest in  certificates  of
participation, which are tax-exempt obligations that evidence the holder's right
to share in lease,  installment  loan or other  financing  payments  by a public
entity.  Projects financed with certificates of participation  generally are not
subject to state constitutional debt limitations or other statutory requirements
that may be applicable to Municipal Securities. Payments by the public entity on
the obligation  underlying the certificates  are derived from available  revenue
sources;  such revenue may be diverted to the funding of other municipal service
projects. Payments of interest and/or principal with respect to the certificates
are not  guaranteed  and do not constitute an obligation of the states or any of
their  political  subdivisions.  While some  municipal  lease  securities may be
deemed to be  "illiquid"  securities  (the purchase of which would be limited as
described below in "Illiquid and Restricted Securities"),  from time to time the
Fund may invest more than 5% of its net assets in  municipal  lease  obligations
that the Manager has determined to be liquid under  guidelines set by the Fund's
Board of  Trustees.  See  "Municipal  Lease  Obligations"  in the  Statement  of
Additional Information for more details.

      o  Floating   Rate/Variable  Rate  Obligations.   Some  of  the  Municipal
Securities the Fund may purchase may have variable or floating  interest  rates.
Variable  rates are adjusted at stated  periodic  intervals.  Floating rates are
automatically   adjusted   according  to  a  specified   market  rate  for  such
investments,  such as the  percentage of the prime rate of a bank, or the 91-day
U.S.  Treasury  Bill rate.  Such  obligations  may be secured by bank letters of
credit or other credit support  arrangements.  See "Floating  Rate/Variable Rate
Obligations" in the Statement of Additional Information for more details.

      o Inverse  Floaters  and  Derivative  Investments.  The Fund may invest in
variable rate bonds known as "inverse  floaters."  These bonds pay interest at a
rate that varies as the yields  generally  available  on  short-term  tax-exempt
bonds  change.  However,  the yields on inverse  floaters  move in the  opposite
direction of yields on short-term bonds in response to market changes.  When the
yields on  short-term  tax-exempt  bonds go up, the interest rate on the inverse
floater goes down. When the yields on short-term  tax-exempt  bonds go down, the
interest rate on the inverse  floater goes up. As interest  rates rise,  inverse
floaters produce less current income. Inverse floaters are a type of "derivative
security," which is a specially designed  investment whose performance is linked
to the performance of another security or investment. Some inverse floaters have
a "cap"  whereby if  interest  rates rise  above the  "cap," the  security  pays
additional  interest income. If rates do not rise above the "cap," the Fund will
have paid an additional amount for a feature that proves worthless. The Fund may
also invest in municipal derivative securities that pay interest that depends on
an external  pricing  mechanism.  Examples are  interest  rate swaps or caps and
municipal  bond or swap indices.  The Fund  anticipates  that it would invest no
more than 10% of its total assets in inverse floaters.

      o "When-Issued" and "Delayed Delivery" Transactions. The Fund may purchase
Municipal Securities on a "when-issued" basis and may purchase or sell Municipal
Securities  on a  "delayed  delivery"  basis.  When  the Fund  engages  in these
transactions,  it will do so for the purpose of acquiring  portfolio  securities
consistent  with the Fund's  investment  objective  and policies and not for the
purpose of investment  leverage.  These terms refer to securities that have been
created and for which a market exists, but which are not available for immediate
delivery.  There may be a risk of loss to the Fund if the value of the  security
declines  prior to the  settlement  date.  When the Fund is the  buyer,  it will
segregate with its custodian cash or high-grade  Municipal  Securities  having a
total value equal to the amount of the Fund's purchase commitments until payment
is made.

      o  Puts  and  Stand-By   Commitments.   The  Fund  may  acquire  "stand-by
commitments"  or  "puts"  with  respect  to  municipal  obligations  held in its
portfolio.  Under a stand-by  commitment or put option,  the Fund would have the
right to sell specified  securities at a specific price on demand to the issuing
broker-dealer or bank. The Fund will acquire stand-by commitments or puts solely
to  facilitate  portfolio  liquidity  and does not intend to exercise its rights
thereunder for trading purposes.

      o Repurchase Agreements. The Fund may enter into repurchase agreements. In
a repurchase  transaction,  the Fund buys a security and simultaneously sells it
to the vendor for delivery at a future date.  There is no limit on the amount of
the Fund's net assets that may be subject to repurchase agreements of seven days
or less.  Repurchase  agreements must be fully  collateralized.  However, if the
vendor fails to pay the resale price on the  delivery  date,  the Fund may incur
costs in disposing of the collateral  and may experience  losses if there is any
delay  in its  ability  to do so.  The  Fund  will  not  enter  into  repurchase
transactions  that will  cause more than 25% of the  Fund's  total  assets to be
subject to repurchase  agreements and will not enter into a repurchase agreement
that  causes  more  than  10% of its net  assets  to be  subject  to  repurchase
agreements  having  a  maturity  beyond  seven  days,  because  such  repurchase
agreements may be illiquid (see "Illiquid and Restricted Securities").

      o Loans of Portfolio  Securities.  To attempt to increase its income,  the
Fund may lend its portfolio  securities to brokers,  dealers and other financial
institutions. The Fund must receive collateral for such loans. The Fund does not
intend to lend its portfolio securities;  if it does, these loans are limited to
not more than 5% of the value of the  Fund's  total  assets  and are  subject to
other  conditions  described in the  Statement of  Additional  Information.  The
income  from such  loans,  when  distributed  by the Fund,  will be  taxable  as
ordinary income.

   
      o Illiquid and  Restricted  Securities.  Under the policies and procedures
established  by the  Fund's  Board  of  Trustees,  the  Manager  determines  the
liquidity  of certain of the Fund's  investments.  Investments  may be  illiquid
because of the absence of an active trading market, making it difficult to value
them or dispose of them promptly at an acceptable  price. A restricted  security
is one that has a  contractual  restriction  on its  resale  or which  cannot be
publicly sold until it is registered  under the Securities Act of 1933. The Fund
will not  invest  more than 10% of its net  assets  in  illiquid  or  restricted
securities (the Board may increase that limit to 15%). Such securities  include:
(i) repurchase  agreements maturing in more than seven days; (ii) securities for
which market quotations are not  readily-available;  and (iii) certain municipal
lease obligations that are considered illiquid securities. The Fund's percentage
limitation on these investments does not apply to certain restricted  securities
that are  eligible  for resale to qualified  institutional  buyers.  The Manager
monitors  holdings  of  illiquid  securities  on an ongoing  basis to  determine
whether to sell any holdings to maintain adequate liquidity. Illiquid securities
include  repurchase  agreements  maturing  in more than seven  days,  or certain
participation  interests  other than those with puts  exercisable  within  seven
days.
    

      o Hedging.  As  described  below,  the Fund may  purchase and sell certain
kinds of futures contracts, put and call options, forward contracts, and options
on  futures  and  municipal  bond  indices,  or enter  into  interest  rate swap
agreements.  These are referred to as "hedging instruments." The Fund may invest
in financial  futures contracts and related options on those contracts only as a
hedge against anticipated interest rate changes, and the Fund does not intend to
use hedging  instruments for speculative  purposes.  The hedging instruments the
Fund may use are  described  below and in  greater  detail in "Other  Investment
Techniques and Strategies" in the Statement of Additional Information.

      The Fund may buy and sell  options,  futures and forward  contracts  for a
number of  purposes.  It may do so to  establish  a position  in the  securities
market as a temporary substitute for purchasing individual securities.  The Fund
may sell a futures contract or a call option on a futures contract or purchase a
put option on such futures  contract if the Manager  anticipates  that  interest
rates  will  rise,  as a hedge  against a  decrease  in the value of the  Fund's
portfolio  securities.  If the  Manager  anticipates  that  interest  rates will
decline,  the Fund may purchase a futures contract or a call option on a futures
contract,  or sell a put option on a futures  contract,  to  protect  against an
increase in the price of securities the Fund intends to buy.

      Other hedging strategies, such as buying futures and call options, tend to
increase the Fund's  exposure to the  securities  market.  Writing  covered call
options may also provide  income to the Fund for liquidity  purposes or to raise
cash to distribute to
shareholders.

      o Futures.  The Fund may buy and sell  financial  futures  contracts  that
relate to (1) interest  rates (these are referred to as Interest Rate  Futures);
and (2) municipal  bond indices  (these are referred to as Municipal  Bond Index
Futures).  These types of Futures are  described  in "Hedging  With  Options and
Futures  Contracts"  in the Statement of  Additional  Information.  The Fund may
concurrently  buy and sell  Futures  contracts in an attempt to benefit from any
outperformance of the Future purchased relative to the performance of the Future
sold. The Fund may not enter into futures  contracts or purchase related options
on futures contracts,  for other than bona fide hedging purposes, if immediately
after doing so the amount the Fund  committed to initial  margin plus the amount
paid for unexpired  options on futures  contracts exceeds 5% of the Fund's total
assets.

   
      o Put and Call  Options.  The Fund  may buy and sell  exchange-traded  and
over-the-counter  put and call  options,  including  index  options,  securities
options,  and  options on the other  types of futures  described  in  "Futures,"
above. A call or put may be purchased only if, after the purchase,  the value of
all call and put options held by the Fund will not exceed 5% of the Fund's total
assets.

      If the Fund sells (that is,  writes) a call option,  it must be "covered."
That means the Fund must own the security  subject to the call while the call is
outstanding,  or, for other  types of  written  calls,  the Fund must  segregate
liquid assets to enable it to satisfy its  obligations if the call is exercised.
When the Fund writes a call, it receives cash (called a premium). The call gives
the buyer the ability to buy the  investment  on which the call was written from
the Fund at the call price during the period in which the call may be exercised.
If the value of the investment  does not rise above the call price, it is likely
that the call will lapse without being exercised,  while the Fund keeps the cash
premium  (and the  investment).  Up to 20% of the  Fund's  total  assets  may be
subject to calls.

    
    
    The  Fund  may buy  puts  whether  or not it  holds  the
underlying  investment  in  the  portfolio.  Buying  a put  on an
investment  gives the Fund the right to sell the  investment at a
set  price to a seller of a put on that  investment.  If the Fund
writes  a put,  the put  must be  covered  by  segregated  liquid
assets.  The Fund  will not  write  puts if more  than 20% of the
Fund's  total  assets  would have to be  segregated  to cover put
options.
    

      o Interest  Rate  Swaps.  In an interest  rate swap,  the Fund and another
party exchange  their right to receive or their  obligation to pay interest on a
security.  For example,  they may swap a right to receive floating rate payments
for fixed rate payments.  The Fund enters into swaps only on securities it owns.
The Fund may not enter  into  swaps  with  respect to more than 25% of its total
assets.  Also,  the Fund  will  segregate  liquid  assets  (such as cash or U.S.
Government securities) to cover any amounts it could owe under swaps that exceed
the amounts it is entitled to receive,  and it will adjust that amount daily, as
needed.  The credit risk of an interest rate swap depends on the  counterparty's
ability to perform.

          Other   Investment   Restrictions.   The  Fund  has  other  investment
     restrictions  which  are  fundamental  policies.  Under  these  fundamental
     policies, the Fund cannot do any of the following:

      o borrow money, except from banks for temporary purposes in amounts not in
excess of 5% of the  value of the  Fund's  assets;  no assets of the Fund may be
pledged, mortgaged or hypothecated other than to secure a borrowing, and then in
amounts not exceeding 10% of the Fund's total assets; borrowings may not be made
for leverage,  but only for liquidity  purposes to satisfy  redemption  requests
when  liquidation  of  portfolio   securities  is  considered   inconvenient  or
disadvantageous;  however,  the Fund may  enter  into  when-issued  and  delayed
delivery transactions as described herein;
      o make loans,  except that the Fund may purchase or hold debt obligations,
repurchase  agreements and other  instruments  and securities it is permitted to
own and may lend its portfolio
securities and other investments it owns;
      o buy  securities  issued or guaranteed by any one issuer (except the U.S.
Government or any of its agencies or instrumentalities),  if with respect to 75%
of its total  assets,  more than 5% of the Fund's total assets would be invested
in  securities  of that  issuer  or the Fund  would  own  more  than 10% of that
issuer's voting securities; or
      o invest more than 25% of its total assets in a single industry  (although
the Fund may invest more than 25% of its assets in a  particular  segment of the
municipal  bond market,  it will not invest more than 25% of its total assets in
industrial revenue bonds in a single industry).

      Unless the prospectus states that a percentage  restriction  applies on an
ongoing basis, it applies only at the time the Fund makes an investment, and the
Fund need not sell securities to meet the percentage  limits if the value of the
investment  increases in  proportion to the size of the Fund.  Other  investment
restrictions  are  listed  in  "Investment  Restrictions"  in the  Statement  of
Additional Information.

How the Fund is Managed

     Organization  and History.  The Fund is one of two  diversified  investment
portfolios or "series" of Oppenheimer Municipal Fund (the "Trust"), an open-end,
management  investment  company  organized as a Massachusetts  business trust in
1986.

   
      The Trust is governed by a Board of Trustees,  which is responsible  under
Massachusetts  law for  protecting the interests of  shareholders.  The Trustees
meet periodically  throughout the year to oversee the Fund's activities,  review
its performance,  and review the actions of the Manager.  "Trustees and Officers
of the Trust" in the Statement of Additional  Information names the Trustees and
officers of the Trust and provides  more  information  about them . Although the
Fund will not normally hold annual  meetings of Fund  shareholders,  it may hold
shareholder  meetings from time to time on important  matters,  and shareholders
have the right to call a meeting  to remove a Trustee  or to take  other  action
described in the Declaration of Trust.
    

      The Board of Trustees  has the power,  without  shareholder  approval,  to
divide unissued shares of the Fund into two or more classes.  The Board has done
so, and the Fund  currently  has three  classes  of shares,  Class A Class B and
Class C. All three classes invest in the same investment  portfolio.  Each class
has its own dividends and  distributions  and pays certain expenses which may be
different for the different  classes.  Each class may have a different net asset
value. Shares are freely  transferrable.  Each share has one vote at shareholder
meetings,  with  fractional  shares  voting  proportionally.  Only  shares  of a
particular class vote as a class on matters that affect that class alone. Please
refer to "How the Fund is Managed" in the Statement of Additional Information on
voting of shares.

The  Manager  and  Its   Affiliates.   The  Fund  is  managed  by  the  Manager,
OppenheimerFunds,   Inc.,   which  is  responsible   for  selecting  the  Fund's
investments  and handles its day-to-day  business.  The Manager  carries out its
duties,  subject to the policies established by the Board of Trustees,  under an
Investment Advisory Agreement which states the Manager's  responsibilities.  The
Agreement sets forth the fees paid by the Fund to the Manager, and describes the
expenses that the Fund is responsible to pay to conduct its business.

   
      The Manager has operated as an investment  advisor since 1959. The Manager
(including subsidiaries) currently manages investment companies, including other
Oppenheimer funds, with assets of more than $75 billion as of December 31, 1997,
with  more  than 3.5  million  shareholder  accounts.  The  Manager  is owned by
Oppenheimer Acquisition Corp., a holding company that is owned in part by senior
officers of the Manager and  controlled by  Massachusetts  Mutual Life Insurance
Company.

      The  management  services  provided  to the Fund by the  Manager,  and the
services  provided by the  Distributor  and the Transfer Agent to  shareholders,
depend on the  smooth  functioning  of their  computer  systems.  Many  computer
software  systems in use today  cannot  distinguish  the year 2000 from the year
1900 because of the way dates are encoded and  calculated.  That  failure  could
have a negative  impact on  handling  securities  trades,  pricing  and  account
services.  The Manager,  the  Distributor  and Transfer Agent have been actively
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.
    

     o Portfolio Manager.  The Portfolio Manager of the Fund is Caryn Halbrecht,
a Vice President of the Manager. She has been the person principally responsible
for the day-to-day  management of the Fund's portfolio since October,  1993. Ms.
Halbrecht was previously a Vice President of Fixed Income  Portfolio  Management
at Bankers Trust.

   
      o Fees and Expenses.  Under the Investment  Advisory  Agreement,  the Fund
pays the Manager the following annual fees,  which decline on additional  assets
as the Fund  grows:  0.500% of the first  $100  million  of  average  annual net
assets,  0.450% of the next $150 million,  0.425% of the next $250 million,  and
0.400% of average annual net assets over $500 million. The Fund's management fee
for its last fiscal year ended  September  30, 1997 was 0.50% of average  annual
net assets for its Class A, Class B and Class C shares.

      The Fund pays expenses related to its daily operations,  such as custodian
fees, Trustees' fees, transfer agency fees, legal fees and auditing costs. Those
expenses  are  paid  out of the  Fund's  assets  and are not  paid  directly  by
shareholders.  However,  those expenses reduce the net asset value of the Fund's
shares,  and  therefore  are  indirectly  borne by  shareholders  through  their
investment.  More information  about the Investment  Advisory  Agreement and the
other  expenses  paid by the Fund is  contained in the  Statement of  Additional
Information.

      There  is  also  information  about  the  Fund's  brokerage  policies  and
practices in  "Brokerage  Policies of the Fund" in the  Statement of  Additional
Information. That section discusses how brokers and dealers are selected for the
Fund's portfolio transactions.  Because the Fund purchases most of its portfolio
securities  directly  from the  sellers and not through  brokers,  it  therefore
incurs relatively little expense for brokerage.  From time to time,  however, it
may use brokers when buying portfolio securities. When deciding which brokers to
use, the Manager is permitted by the Investment  Advisory  Agreement to consider
whether  brokers  have sold  shares of the Fund or any other funds for which the
Manager serves as investment advisor.

      o The  Distributor.  The Fund's shares are sold through  dealers , brokers
and financial  institutions  that have a sales  agreement with  OppenheimerFunds
Distributor,  Inc.,  a  subsidiary  of the  Manager  that  acts  as  the  Fund's
Distributor.  The Distributor also  distributes the shares of other  Oppenheimer
funds and is sub- distributor for funds managed by a subsidiary of the Manager.

      o The  Transfer  Agent.  The  Fund's  transfer  agent is  OppenheimerFunds
Services,  a division of the Manager,  which acts as the  shareholder  servicing
agent  for the  Fund on an  "at-cost"  basis.  It also  acts as the  shareholder
servicing  agent  for  other  Oppenheimer  funds.   Shareholders  should  direct
inquiries  about  their  accounts  to the  Transfer  Agent  at the  address  and
toll-free  number  shown  below  in  this  Prospectus  and  on the  back  cover.
Performance of the Fund

Explanation of Performance Terminology.  The Fund uses the terms "total return,"
"average annual total return,"  "standardized  yield," "dividend yield," "yield"
and  "tax-equivalent  yield" to illustrate its  performance.  The performance of
each class of shares is shown separately,  because the performance of each class
of shares  will  usually be  different,  as a result of the  different  kinds of
expenses each class bears. These returns and yields measure the performance of a
hypothetical  account  in the Fund  over  various  periods,  and do not show the
performance  of each  shareholder's  account  (which will vary if dividends  are
received in cash, or shares are sold or purchased).  The Fund's  performance may
help you see how well your Fund has done  over time and to  compare  it to other
funds or to a market index.
    

      It is important  to  understand  that the Fund's total  returns and yields
represent  past  performance  and should not be considered to be  predictions of
future returns or performance.  This  performance  data is described  below, but
more detailed  information  about how total returns and yields are calculated is
contained  in the  Statement  of  Additional  Information,  which also  contains
information  about  indices  and other ways to measure  and  compare  the Fund's
performance. The Fund's investment performance will vary over time, depending on
market conditions, the composition of the portfolio, expenses and which class of
shares you purchase.

      o Total  Returns.  There are  different  types of "total  returns" used to
measure  the  Fund's  performance.  Total  return  is the  change  in value of a
hypothetical  investment  in the Fund  over a given  period,  assuming  that all
dividends and capital gains  distributions are reinvested in additional  shares.
The cumulative  total return measures the change in value over the entire period
(for example,  ten years). An average annual total return shows the average rate
of return for each year in a period  that would  produce  the  cumulative  total
return over the entire period. However, average annual total returns do not show
the Fund's actual year-by-year performance.

      When total  returns  are quoted for Class A shares,  normally  the current
maximum initial sales charge has been deducted. When total returns are shown for
Class B or Class C shares,  normally the  contingent  deferred sales charge that
applies  to the  period  for which  total  return  is shown  has been  deducted.
However,  total  returns  may  also be  quoted  at  "net  asset  value"  without
considering  the effect of the sales charge,  and those returns would be less if
sales charges were deducted.

   
      o Yield. Different types of yields may be quoted to show performance. Each
Class of shares calculates its standardized yield by dividing the annualized net
investment  income per share from the  portfolio  during a 30-day  period by the
maximum  offering  price on the last day of the period.  The yield of each class
will differ because of the different expenses of each class of shares. The yield
data represents a hypothetical investment return on the portfolio,  and does not
measure an investment  return based on dividends  actually paid to shareholders.
To show that  return,  a dividend  yield may be  calculated.  Dividend  yield is
calculated  by dividing the dividends of a class paid for a stated period by the
maximum offering price on the last day of the period and annualizing the result.
Yields for Class A shares normally  reflect the deduction of the maximum initial
sales charge,  but may also be shown without deducting sales charge.  Yields for
Class B and  Class C shares  do not  reflect  the  deduction  of the  contingent
deferred sales charge.  Tax-equivalent  yield is the equivalent yield that would
be earned in the absence of income  taxes.  It is  calculated  by dividing  that
portion  of the  yield  that is  tax-exempt  by a factor  equal to one minus the
applicable tax rate.

How Has the Fund  Performed?  Below is a discussion by the Manager of the Fund's
performance during its last fiscal year ended September 30, 1997,  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
ended   September  30,  1997,  the  Fund's   performance   was  affected  by  an
overweighting  in a  diversified  portfolio of slightly  lower-quality  credits,
which added yield.  The second factor was the  qualification  of several  Triple
B-rated bonds for insurance.  This insurance raises the credit worthiness of the
bond, boosting its price. Further, an overweighting in non-callable  securities,
which perform  better than callable  securities  when interest rates are falling
added yield to the portfolio during this period.  Lastly, the portfolio was able
to enjoy  several  credit-quality  upgrades in the hospital  sector.  The Fund's
portfolio holdings, allocations and strategies are subject to change.

      o Comparing the Fund's  Performance to the Market.  The graphs below shows
the performance of a hypothetical  $10,000 investment in each class of shares of
the Fund held from the  inception of the Class until  September 30, 1997. In the
case of Class A shares,  performance is measured over a ten-year period,  in the
case of Class B shares from the  inception of the class on  September  11, 1995,
and in the case of Class C shares,  from the  inception of the class on December
1, 1993.
    

     The Fund's performance is compared to that of the Lehman Brothers Municipal
Bond Index,  an unmanaged  index of a broad range of investment  grade municipal
bonds that is widely  regarded  as a measure of the  performance  of the general
municipal bond market. Index performance reflects the reinvestment of income but
does not consider the effect of capital gains or transaction  costs, and none of
the data below  shows the effect of taxes.  Also,  the Fund's  performance  data
reflects  the  effect 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
any one  index.  Moreover,  the  index  performance  data does not  reflect  any
assessment of the risk of the investments included in the index.

How to Buy Shares

Classes of Shares.  The Fund offers investors three different classes of shares.
The different  classes of shares represent  investments in the same portfolio of
securities but are subject to different  expenses and will likely have different
share prices.

   
      o Class A  Shares.  If you buy Class A shares,  you pay an  initial  sales
charge (on investments up to $1 million). If you purchase Class A shares as part
of an  investment  of at least $1 million  in shares of one or more  Oppenheimer
funds,  you will not pay an initial sales  charge,  but if you sell any of those
shares  within 12 months of buying them (18 months if the shares were  purchased
prior to May 1, 1997),  you may pay a  contingent  deferred  sales  charge.  The
amount of that sales  charge  will vary  depending  on the amount you  invested.
Sales charge rates are described in "Buying Class A Shares," below.
    

      o Class B Shares.  If you buy Class B shares,  you pay no sales  charge at
the time of  purchase,  but if you sell your  shares  within six years of buying
them,  you will  normally pay a contingent  deferred  sales  charge.  That sales
charge varies depending on how long you own your shares, as described in "Buying
Class B Shares" below.

      o Class C Shares.  If you buy Class C shares,  you pay no sales  charge at
the time of  purchase,  but if you sell your  shares  within 12 months of buying
them,  you will  normally pay a  contingent  deferred  sales charge of 1.0%,  as
described in "Buying Class C Shares" below.

Which  Class of Shares  Should You  Choose?  Once you decide that the Fund is an
appropriate  investment  for you,  the  decisions as to which class of shares is
best  suited to your  needs  depends  on a number of  factors  which you  should
discuss with your financial advisor.  The Fund's operating costs that apply to a
class of shares and the effect of the  different  types of sales charges on your
investment  will vary your  investment  results  over time.  The most  important
factors  to  consider  are how much you plan to invest  and how long you plan to
hold your investment. If your goals and objectives change over time and you plan
to purchase  additional  shares,  you should re-evaluate those factors to see if
you should consider another class of shares.

      In the  following  discussion,  to help  provide  you and  your  financial
advisor  with a  framework  in  which  to  choose a  class,  we have  made  some
assumptions  using a  hypothetical  investment  in the  Fund.  We used the sales
charge  rates that apply to each class and  considered  the effect of the annual
asset-based  sales  charge  on Class B and  Class C  expenses  (which,  like all
expenses,  will affect your investment return).  For the sake of comparison,  we
have assumed that there is a 10% rate of  appreciation  in the  investment  each
year. Of course,  the actual  performance of your investment cannot be predicted
and will vary, based on the Fund's actual  investment  returns and the operating
expenses borne by each class of shares, and which class of shares you invest in.

      The factors  discussed  below are not intended to be investment  advice or
recommendations, because each investor's financial considerations are different.
The discussion below of the factors to consider in purchasing a particular class
of shares  assumes that you will  purchase  only one class of shares,  and not a
combination of shares of different classes.

   
      o How Long Do You Expect to Hold Your  Investment?  While future financial
needs cannot be predicted  with  certainty,  knowing how long you expect to hold
your investment  will assist you in selecting the  appropriate  class of shares.
Because of the effect of class-based  expenses,  your choice will also depend on
how much you plan to invest.  For example,  the reduced sales charges  available
for larger  purchases  of Class A shares  may,  over time,  offset the effect of
paying an initial sales charge on your  investment  (which reduces the amount of
your  investment  dollars used to buy shares for your account),  compared to the
effect over time of higher class-based expenses on Class B or Class C shares for
which no initial sales charge is paid.

      o  Investing  for the  Short  Term.  If you have a  short-term  investment
horizon (that is, you plan to hold your shares for not more than six years), you
should probably consider  purchasing Class A or Class C shares rather than Class
B shares,  because of the effect of the Class B contingent deferred sales charge
if you redeem within six years, as well as the effect of the Class B asset-based
sales charge on the investment return for that class in the short-term.  Class C
shares might be the appropriate  choice (especially for investments of less than
$100,000)  because there is no initial  sales charge on Class C shares,  and the
contingent  deferred  sales  charge  does not apply to  amounts  you sell  after
holding them one year.
    

      However,  if you plan to invest more than  $100,000 for the shorter  term,
then the more you invest and the more your investment  horizon  increases toward
six years,  Class C shares might not be as advantageous as Class A shares.  That
is because  the annual  asset-based  sales  charge on Class C shares will have a
greater  impact on your account over the longer term than the reduced  front-end
sales charge  available  for larger  purchases  of Class A shares.  For example,
Class A shares might be more  advantageous than Class C shares (as well as Class
B shares) for  investments of more than $100,000  expected to be held for 5 or 6
years (or more). For investments over $250,000  expected to be held 4 to 6 years
(or more),  Class A shares may become more advantageous than Class C shares (and
Class B  shares).  If  investing  $500,000  or more,  Class A shares may be more
advantageous as your investment horizon approaches 3 years or more.

      And for  investors  who invest $1 million or more,  in most cases  Class A
shares will be the most  advantageous  choice,  no matter how long you intend to
hold your shares.  For that reason,  the  Distributor  normally  will not accept
purchase  orders of  $500,000 or more of Class B shares or $1 million or more of
Class C shares from a single investor.

      o Investing for the Longer Term. If you are investing for the longer term,
for example, for retirement,  and do not expect to need access to your money for
seven years or more, Class B shares may be an appropriate consideration,  if you
plan to invest less than $100,000. If you plan to invest more than $100,000 over
the long term,  Class A shares  will  likely be more  advantageous  than Class B
shares or Class C shares,  as  discussed  above,  because  of the  effect of the
expected lower expenses for Class A shares and the reduced initial sales charges
available  for larger  investments  in Class A shares  under the Fund's Right of
Accumulation.

      Of course,  these  examples are based on  approximations  of the effect of
current sales charges and expenses on a hypothetical investment over time, using
the assumed  annual  performance  return stated above,  and therefore you should
analyze your options carefully.

      o Are There  Differences in Account  Features That Matter to You?  Because
some account  features such as  checkwriting  may not be available to Class B or
Class C shareholders, or other features (such as Automatic Withdrawal Plans) may
not be advisable (because of the effect of the contingent deferred sales charge)
for Class B or Class C shareholders, you should carefully review how you plan to
use your  investment  account  before  deciding  which  class of  shares to buy.
Additionally,  dividends  payable  to Class B and Class C  shareholders  will be
reduced by the additional  expenses borne by those classes that are not borne by
Class A  shares,  such as the  Class B and  Class C  asset-based  sales  charges
described  below  and  in  the  Statement  of  Additional   Information.   Share
certificates  are not  available  for Class B and Class C shares  and if you are
considering  using your shares as collateral for a loan, that may be a factor to
consider.

   
      o How Does It Affect  Payments  to My  Broker?  A  salesperson,  such as a
broker, or any other person who is entitled to receive  compensation for selling
Fund shares may receive  different  compensation for selling one class of shares
than for selling another class.  It is important that investors  understand that
the  purpose of the Class B and Class C  contingent  deferred  sales  charge and
asset-based  sales  charges is the same as the  purpose of the  front-end  sales
charge on sales of Class A shares:  that is, to compensate the  Distributor  for
commissions it pays to dealers and financial  institutions  for selling  shares.
The Distributor may pay additional periodic  compensation from its own resources
to securities  dealers or financial  institutions based upon the value of shares
of the Fund owned by the dealer or financial  institution for its own account or
for its customers.
    

How Much Must You Invest?  You can open a Fund  account  with a minimum  initial
investment of $1,000 and make additional  investments at any time with as little
as $25. There are reduced minimum investments under special investment plans.

      With Asset Builder Plans,  Automatic Exchange Plans and military allotment
plans, you can make initial and subsequent investments for as little as $25; and
subsequent  purchases  of  at  least  $25  can  be  made  by  telephone  through
AccountLink.

      There is no minimum  investment  requirement  if you are buying  shares by
reinvesting  dividends from the Fund or other  Oppenheimer funds (a list of them
appears in the Statement of Additional  Information,  or you can ask your dealer
or  call  the  Transfer  Agent),  or  by  reinvesting  distributions  from  unit
investment trusts that have made arrangements with the Distributor.

      o How Are Shares Purchased?  You can buy shares several ways --through any
dealer,  broker or financial  institution  that has a sales  agreement  with the
Distributor,  directly through the Distributor,  or automatically from your bank
account  through an Asset  Builder Plan under the  OppenheimerFunds  AccountLink
service.   The  Distributor  may  appoint  certain   servicing   agents  as  the
Distributor's agent to accept purchase (and redemption) orders.
  When you buy shares, be sure to specify Class A, Class B or Class C shares. If
you do not choose, your investment will be made in Class A shares.

      o  Buying  Shares  Through  Your  Dealer.  Your  dealer  will
place your order with the Distributor on your behalf.

      o Buying Shares Through the Distributor.  Complete an OppenheimerFunds New
Account  Application  and return it with a check  payable  to  "OppenheimerFunds
Distributor,  Inc." Mail it to P.O. Box 5270,  Denver,  Colorado  80217.  If you
don't list a dealer on the  application,  the Distributor will act as your agent
in  buying  the  shares.  However,  it is  recommended  that  you  discuss  your
investment first with a financial advisor, to be sure that it is appropriate for
you.

     o Payment by Federal  Funds Wire.  Shares may be purchased by Federal Funds
wire. The minimum  investment is $2,500.  You must first call the  Distributor's
Wire Department at  1-800-525-7041 to notify the Distributor of the wire, and to
receive further instructions.

   
      o  Buying  Shares  Through  OppenheimerFunds   AccountLink.  You  can  use
AccountLink  to link your Fund account  with an account at a U.S.  bank or other
financial  institution  that is an  Automated  Clearing  House  (ACH)  member to
transmit funds  electronically  to purchase  shares,  to have the Transfer Agent
send redemption proceeds or to transmit dividends and distributions.  Shares are
purchased  for your  account on  AccountLink  on the  regular  business  day the
Distributor is instructed by you to initiate the ACH transfer to buy shares. You
can provide  those  instructions  automatically,  under an Asset  Builder  Plan,
described below, or by telephone instructions using OppenheimerFunds  PhoneLink,
also  described  below.  You  should  request  AccountLink   privileges  on  the
application or dealer  settlement  instructions  used to establish your account.
Please refer to "AccountLink" below for more details.
    

      o Asset Builder Plans. You may purchase shares of the Fund (and up to four
other Oppenheimer funds) automatically each month from your account at a bank or
other  financial  institution  under an Asset  Builder  Plan  with  AccountLink.
Details are in the Statement of Additional Information.


   
      o At What Price Are Shares  Sold?  Shares are sold at the public  offering
price based on the net asset value (and any initial  sales charge that  applies)
that is next  determined  after the  Distributor  receives the purchase order in
Denver, Colorado, or the order is received and transmitted to the Distributor by
an entity  authorized by the Fund to accept purchase or redemption  orders.  The
Fund has  authorized  the  Distributor,  certain  broker-dealers  and  agents or
intermediaries  designated by the Distributor or those  broker-dealers to accept
orders.  In most cases, to enable you to receive that day's offering price,  the
Distributor  or an authorized  entity must receive your order by the time of day
The New York Stock Exchange closes,  which is normally 4:00 P.M., New York time,
but may be earlier on some days (all  references to time in this Prospectus mean
"New York time").  The net asset value of each class of shares is  determined as
of that  time on each  day The New  York  Stock  Exchange  is open  (which  is a
"regular business day").

      If you buy shares through a dealer,  the dealer must receive your order by
the close of The New York Stock Exchange on a regular  business day and normally
your order must be transmitted to the  Distributor so that it is received before
the  Distributor's  close of business that day,  which is normally 5:00 P.M. The
Distributor,  in its sole  discretion,  may  reject any  purchase  order for the
Fund's shares.
    

Special  Sales  Charge  Arrangements  for  Certain  Persons.  Appendix A in this
prospectus  sets forth  conditions for the waiver of, or exemption  from,  sales
charges or the special  sales  charge rates that apply to purchases of shares of
the Fund (including  purchases by exchange) by a person who was a shareholder of
one of the former Quest for Value Funds (as defined in that Appendix).

Buying Class A Shares. Class A shares are sold at their offering price, which is
normally net asset value plus an initial sales charge.  However,  in some cases,
described below,  purchases are not subject to an initial sales charge,  and the
offering price will be the net asset value. In some cases, reduced sales charges
may be available,  as described  below.  Out of the amount you invest,  the Fund
receives the net asset value to invest for your account. The sales charge varies
depending on the amount of your  purchase.  A portion of the sales charge may be
retained by the  Distributor  and  allocated to your dealer as  commission.  The
current  sales charge rates and  commissions  paid to dealers and brokers are as
follows:

                          Front-End       Front-End

The Distributor  reserves the right to reallow the entire commission to dealers.
If that occurs,  the dealer may be  considered  an  "underwriter"  under Federal
securities laws.

      o Class A Contingent  Deferred  Sales  Charge.  There is no initial  sales
charge  on  purchases  of Class A shares  of any one or more of the  Oppenheimer
funds  aggregating  $1 million or more. The  Distributor  pays dealers of record
commissions  on those non-  retirement  plan purchases in an amount equal to the
sum of 1.0%.  That commission will be paid only on the amount of those purchases
that  were not  previously  subject  to a  front-end  sales  charge  and  dealer
commission.

   
      If you redeem any of those shares  purchased prior to May 1, 1997,  within
18 months  of the end of the  calendar  month of their  purchase,  a  contingent
deferred  sales charge  (called the "Class A contingent  deferred sales charge")
may be deducted  from the  redemption  proceeds.  A Class A contingent  deferred
sales charge may be deducted from the redemption proceeds of any of those shares
purchased on or after May 1, 1997 that are redeemed  within 12 months of the end
of the calendar month of their purchase.  That sales charge may be equal to 1.0%
of the lesser of (1) the aggregate  net asset value of the redeemed  shares (not
including  shares  purchased  by  reinvestment  of  dividends  or  capital  gain
distributions)  or (2) the  original  offering  price (which is the original net
asset value) of the redeemed shares.  However,  the Class A contingent  deferred
sales  charge  will not  exceed  the  aggregate  amount of the  commissions  the
Distributor  paid to your dealer on all Class A shares of all Oppenheimer  funds
you  purchased  subject to the Class A  contingent  deferred  sales  charge.  In
determining whether a contingent deferred sales charge is payable, the Fund will
first redeem shares that are not subject to the sales charge,  including  shares
purchased by reinvestment  of dividends and capital gains,  and then will redeem
other  shares in the  order  that you  purchased  them.  The Class A  contingent
deferred sales charge is waived in certain cases  described in "Waivers of Class
A Sales Charges" below.

      No Class A  contingent  deferred  sales  charge is charged on exchanges of
shares under the Fund's Exchange Privilege  (described below).  However,  if the
shares  acquired by exchange are redeemed  within 12 calendar  months (18 months
for shares  purchased  prior to May 1, 1997) of the end of the calendar month of
the purchase of the exchanged shares, the sales charge will apply.
    

      o Special  Arrangements With Dealers. The Distributor may advance up to 13
months' commissions to dealers that have established  special  arrangements with
the Distributor for Asset Builder Plans for their clients.

     Reduced Sales Charges for Class A Share  Purchases.  You may be eligible to
buy Class A shares at reduced sales charge rates in one or more of the following
ways:

      o Right of Accumulation.  To qualify for the lower sales charge rates that
apply to  larger  purchases  of Class A  shares,  you and  your  spouse  can add
together Class A and Class B shares you purchase for your  individual  accounts,
or jointly,  or for trust or custodial  accounts on behalf of your  children who
are minors.  A fiduciary can count all shares  purchased for a trust,  estate or
other  fiduciary  account  (including one or more employee  benefit plans of the
same employer) that has multiple accounts.

   
      Additionally,  you can add together current purchases of Class A and Class
B shares of the Fund and other Oppenheimer funds to reduce the sales charge rate
that applies to current purchases of Class A shares.  You can also include Class
A and Class B shares of Oppenheimer funds you previously purchased subject to an
initial or contingent  deferred sales charge to reduce the sales charge rate for
current  purchases  of  Class A  shares,  provided  that  you  still  hold  your
investment in one of the Oppenheimer  funds. The Distributor will add the value,
at current offering price, of the shares you previously  purchased and currently
own to the value of current  purchases to  determine  the sales charge rate that
applies.  The  Oppenheimer  funds are listed in "Reduced  Sales  Charges" in the
Statement  of  Additional  Information,  or a list  can  be  obtained  from  the
Distributor.  The reduced sales charge will apply only to current  purchases and
must be requested when you buy your shares.
    

     o Letter of  Intent.  Under a Letter of  Intent,  if you  purchase  Class A
shares or Class A and Class B shares  of the Fund and  other  Oppenheimer  funds
during a 13-month  period,  you can reduce the sales charge rate that applies to
your purchases of Class A shares. The total amount of your intended purchases of
both Class A and Class B shares will determine the reduced sales charge rate for
the Class A shares purchased during that period. This can include purchases made
up to 90 days before the date of the Letter.  More  information  is contained in
the  Application  and in "Reduced  Sales Charges" in the Statement of Additional
Information.

   
      o Waivers  of Class A Sales  Charges.  The Class A sales  charges  are not
imposed in the  circumstances  described below.  There is an explanation of this
policy in "Reduced Sales Charges" in the Statement of Additional Information. In
order to receive a waiver of the Class A contingent  deferred sales charge,  you
must notify the Transfer Agent which conditions apply.
    

      Waivers of Initial  and  Contingent  Deferred  Sales  Charges  for Certain
Purchasers.  Class A shares purchased by the following investors are not subject

Distributor at the time of purchase that the purchase is for the purchaser's own
account (or for the benefit of such employee's spouse or minor children);

   
      o dealers,  brokers, banks or registered investment advisers advisors that

dealer, broker, bank or advisor for the purchase or sale of Fund shares);

      o (1) investment  advisors and financial planners who have entered into an
agreement  for this  purpose  with the  Distributor  and who charge an advisory,
consulting or other fee for their services and buy shares for their own accounts
or the accounts of their  clients,  (2) "rabbi trusts" that buy shares for their
own accounts, in each case if those purchases are made through a broker or agent

Distributor for those purchases;  and (3) clients of such investment advisors or
financial  planners  (that have entered into an agreement  for this purpose with
the  Distributor) who buy shares for their own accounts may also purchase shares
without sales charge but only if their  accounts are linked to a master  account
of their investment advisor or financial planner on the books and records of the
broker, agent or financial intermediary with which the Distributor has made such
special  arrangements  (each  of these  investors  may be  charged  a fee by the
broker, agent or financial intermediary for purchasing shares);
    

      o directors,  trustees,  officers or full-time employees of OpCap Advisors
or its  affiliates,  their  relatives or any trust,  pension,  profit sharing or

or  trustees  of the  company  or trust  which is the  beneficial  owner of such
accounts; or
     

      o any unit investment trust that has entered into an appropriate agreement
with the Distributor.

      Waivers  of  Initial  and  Contingent  Deferred  Sales  Charges in Certain
Transactions.  Class A shares issued or purchased in the following  transactions
are not subject to Class A sales charges:

      o shares  issued  in  plans  of  reorganization,  such as  mergers,  asset
acquisitions and exchange offers, to which the Fund is a party;
      o shares purchased by the reinvestment of dividends or other distributions
reinvested from the Fund or other Oppenheimer funds (other than Oppenheimer Cash
Reserves) or unit investment  trusts for which  reinvestment  arrangements  have
been made with the
Distributor;
   
      o shares  purchased  and paid for with the proceeds of shares  redeemed in
the prior 30 days from a mutual fund  (other than a fund  managed by the Manager
or any of its  subsidiaries)  on which an  initial  sales  charge or  contingent
deferred sales charge was paid (this waiver also applies to shares  purchased by
exchange of shares of  Oppenheimer  Money Market Fund,  Inc. that were purchased
and paid for in this  manner);  this waiver must be requested  when the purchase
order is placed for your  shares of the Fund,  and the  Distributor  may require
evidence of your qualification for this waiver; or
    
      o shares purchased with the proceeds of maturing principal of units of any
Qualified Unit Investment Liquid Trust Series.

      Waivers  of the Class A  Contingent  Deferred  Sales  Charge  for  Certain
Redemptions.  The Class A  contingent  deferred  sales  charge is also waived if
shares that would  otherwise be subject to the contingent  deferred sales charge
are redeemed in the following cases:

      o to make Automatic  Withdrawal Plan payments that are limited annually to
no more than 12% of the original account value;
      o  involuntary  redemptions  of shares by operation of law or  involuntary
redemptions  of small accounts (see  "Shareholders  Account Rules and Policies,"
below); or
   
      o if, at the time of purchase of shares  (prior to May 1, 1997) the dealer
agrees in writing  to accept the  dealer's  portion of the sales  commission  in
installments  of 1/18th of the commission  per month (and no further  commission
will be payable if the shares are redeemed within 18 months of purchase);
      o if, at the time of  purchase of shares (if  purchased  during the period
May 1, 1997 through  December  31, 1997) the dealer  agrees in writing to accept
the dealer's  portion of the sales  commission in  installments of 1/12th of the
commission  per month (and no further  commission  will be payable if the shares
are redeemed within 12 months of purchase);
    

      o Service Plan for Class A Shares. The Fund has adopted a Service Plan for
Class A shares to reimburse the  Distributor for a portion of its costs incurred
in connection  with the personal  service and  maintenance of 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. The
Distributor  uses all of those fees to compensate  dealers,  brokers,  banks and
other  financial  institutions  quarterly  for  providing  personal  service and
maintenance  of  accounts  of their  customers  that hold  Class A shares and to
reimburse   itself   (if  the  Fund's   Board  of   Trustees   authorizes   such
reimbursements,  which it has not yet done) for its other expenditures under the
Plan.

      Services  to  be  provided  include,  among  others,   answering  customer
inquiries about the Fund,  assisting in establishing and maintaining accounts in
the Fund,  making the Fund's  investment  plans  available and  providing  other
services at the request of the Fund or the Distributor. Payments are made by the
Distributor  quarterly  at an  annual  rate not to exceed  0.25% of the  average
annual net assets of Class A shares held in accounts of the service providers or
their  customers.  The payments  under the Plan increase the annual  expenses of
Class A shares.  For more  details,  please refer to  "Distribution  and Service
Plans" in the Statement of Additional Information.

   
Buying  Class B Shares.  Class B shares  are sold at net  asset  value per share
without an initial sales charge.  However, if Class B shares are redeemed within
six years of their purchase, a contingent deferred sales charge will be deducted
from the  redemption  proceeds.  That  sales  charge  will not  apply to  shares
purchased by the reinvestment of dividends or capital gains  distributions.  The
contingent  deferred  sales  charge will be based on the lesser of the net asset
value of the redeemed shares at the time of redemption or the original  offering
price (which is the original net asset value).  The  contingent  deferred  sales
charge is not imposed on the amount of your  account  value  represented  by the
increase  in net  asset  value  over the  initial  purchase  price.  The Class B
contingent  deferred sales charge is paid to compensate the  Distributor for its
expenses of providing  distribution-related  services to the Fund in  connection
with the sale of Class B shares.
    

      To determine  whether the  contingent  deferred  sales charge applies to a
redemption,  the Fund redeems shares in the following order: (1) shares acquired
by  reinvestment of dividends and capital gains  distributions,  (2) shares held
for over six years,  and (3) shares held the longest during the six-year period.
The  contingent  deferred  sales  charge  is not  imposed  in the  circumstances
described in "Waivers of Class B and Class C Sales Charges," below.

      The amount of the  contingent  deferred  sales  charge  will depend on the
number  of years  since you  invested  and the  dollar  amount  being  redeemed,
according to the following schedule:

                                       Contingent Deferred
                                       Sales Charge
Years Since Beginning of Month in      On Redemptions in That Year
which Purchase Order Was Accepted      (As % of Amount  Subject  to
Charge)
- -----------------------------------------------------------------------
0-1                                    4.0%
- -----------------------------------------------------------------------
1-2                                    3.0%
- -----------------------------------------------------------------------
2-3                                    2.0%
- -----------------------------------------------------------------------
3-4                                    2.0%
- -----------------------------------------------------------------------
4-5                                    1.0%
- -----------------------------------------------------------------------
5 and following                        None

     In the table, a "year" is a 12-month  period.  All purchases are considered
to have been made on the first  regular  business  day of the month in which the
purchase was made.

   
     o Automatic  Conversion  of Class B Shares.  72 months after
you  purchase  Class B shares,  those  shares will  automatically
convert to Class A shares. This conversion feature relieves Class
B shareholders  of the  asset-based  sales charge that applies to
Class B shares under the Class B  Distribution  and Service Plan,
described  below.  The  conversion  is based on the  relative net
asset value of the two classes, and no sales load or other charge
is imposed. When Class B shares convert, any other Class B shares
that  were  acquired  by  the   reinvestment   of  dividends  and
distributions  on the converted shares will also convert to Class
A shares.  The  conversion  feature is  subject to the  continued
availability  of a tax ruling  described  in  "Alternative  Sales
Arrangements  - Class  A,  Class B and  Class  C  Shares"  in the
Statement of Additional Information. Buying Class C Shares. Class
C shares are sold at net asset value per share without an initial
sales charge.  However,  if Class C shares are redeemed within 12
months of their purchase, a
contingent  deferred  sales charge of 1.0% will be deducted from the  redemption
proceeds.  That  sales  charge  will  not  apply  to  shares  purchased  by  the
reinvestment  of dividends or capital  gains  distributions.  The charge will be
assessed  on the  lesser  of the net  asset  value of the  shares at the time of
redemption or the original purchase price. The contingent  deferred sales charge
is not imposed on the amount of your account value  represented  by the increase
in net asset  value over the  initial  purchase  price.  The Class C  contingent
deferred sales charge is paid to compensate the  Distributor for its expenses of
providing  distribution-related services to the Fund in connection with the sale
of Class C shares.

      To determine  whether the  contingent  deferred  sales charge applies to a
redemption,  the Fund redeems shares in the following order: (1) shares acquired
by  reinvestment of dividends and capital gains  distributions,  (2) shares held
for over 12 months, and (3) shares held the longest during the 12-month period.
    

Distribution  and  Service  Plans for  Class B and Class C Shares.  The Fund has
adopted  Distribution  and  Service  Plans  for  Class B and  Class C shares  to
compensate  the  Distributor  for  distributing  Class B and Class C shares  and
servicing  accounts.  Under the Plans,  the Fund pays the  Distributor an annual
"asset-based  sales  charge"  of 0.75% per year on Class B shares and on Class C
shares. The Distributor also receives a service fee of 0.25% per year under each
plan.

      Under each Plan,  both fees are  computed  on the average of the net asset
value of  shares in the  respective  class,  determined  as of the close of each
regular business day during the period. The asset-based sales charge and service
fees increase  Class B and Class C expenses by up to 1.00% of the net assets per
year of the respective class.

      The Distributor uses the service fees to compensate  dealers for providing
personal  services  for  accounts  that hold  Class B or Class C  shares.  Those
services are similar to those provided under the Class A Service Plan, described
above. The Distributor pays the 0.25% service fees to dealers in advance for the
first  year  after  Class B or Class C shares  have been sold by the  dealer and
retains  the  service  fee paid by the Fund in that year.  After the shares have
been held for a year,  the  Distributor  pays the  service  fees to dealers on a
quarterly basis.

      The  asset-based  sales charge allows  investors to buy Class B or Class C
shares  without a front-end  sales charge  while  allowing  the  Distributor  to
compensate  dealers that sell those shares.  The Fund pays the asset-based sales
charges to the Distributor for its services rendered in distributing Class B and
Class C shares.  Those  payments  are at a fixed rate that is not related to the
Distributor's  expenses. The services rendered by the Distributor include paying
and financing the payment of sales commissions,  service fees and other costs of
distributing and selling Class B and Class C shares.

   
      The Distributor  currently pays sales commissions of 2.75% of the purchase
price of Class B shares to dealers  from its own  resources at the time of sale.
Including  the  advance  of the  service  fee,  the  total  amount  paid  by the
Distributor to the dealer at the time of sales of Class B shares is 3.00% of the
purchase price.  The Distributor  retains the Class B asset-based  sales charge.
The Distributor may pay the Class B service fee and the asset-based sales charge
to the dealer  quarterly in lieu of paying the sales  commission and service fee
advance at the time of purchase.

      The Distributor  currently pays sales commissions of 0.75% of the purchase
price to dealers  from its own  resources at the time of sale of Class C shares.
Including  the  advance  of the  service  fee,  the  total  amount  paid  by the
Distributor  to the dealer at the time of sale of Class C shares is 1.00% of the
purchase price. The Distributor  plans to pay the asset-based sales charge as an
ongoing  commission  to the dealer on Class C shares that have been  outstanding
for a year or more.  The  Distributor  shall  pay the  Class C  service  fee and
asset-based  sales  charge to the dealer  quarterly  in lieu of paying the sales
commission and service fee advance at the time of purchase.

      The  Distributor's  actual  expenses in selling Class B and Class C shares
may be more than the payments it receives from contingent deferred sales charges
collected  on  redeemed  shares  and from the Fund  under the  Distribution  and
Service  Plans for Class B and Class C  shares.  If the Fund  terminates  either
Plan,  the Board of  Trustees  may allow the Fund to  continue  payments  of the
asset-based  sales charge to the Distributor for distributing  shares before the
Plan was  terminated.  At September 30, 1997,  the end of the Class B Plan year,
the Distributor had incurred  unreimbursed  expenses in connection with sales of
Class B shares of $167,478,  respectively (equal to 2.18%, respectively,  of the
Fund's net assets  represented by Class B shares on that date). At September 30,
1997,  the  end  of  the  Class  C  Plan  year,  the  Distributor  had  incurred
unreimbursed  expenses in  connection  with sales of Class C shares of $186,693,
respectively (equal to 1.34%, respectively, of the Fund's net assets represented
by Class C shares on that date).
    

       
   
      o Waivers  of Class B and Class C Sales  Charges.  The Class B and Class C
contingent  deferred  sales  charges will not be applied to shares  purchased in
certain  types of  transactions  nor will it apply to Class B and Class C shares
redeemed  in certain  circumstances  as  described  below.  The reasons for this
policy  are  in  "Reduced   Sales   Charges"  in  the  Statement  of  Additional
Information.  In order to receive a waiver of the Class B and Class C contingent
deferred  sales  charge,  you must notify the  Transfer  Agent which  conditions
apply.

      Waivers for Redemptions of Shares in Certain Cases.  The Class B and Class
C contingent  deferred  sales charges will be waived for redemption of shares in
the following cases:

      o redemptions from accounts  following the death or disability of the last
surviving  shareholder,  including a trustee of a "grantor"  trust or  revocable
living  trust for which the trustee is also the sole  beneficiary  (the death or
disability  must  have  occurred  after  the  account  was  established  and for
disability  you must provide  evidence of a  determination  of disability by the
Social Security Administration); or
    

      o shares  redeemed  involuntarily,  as described in  "Shareholder  Account
Rules and Policies," below.

     Waivers for Shares Sold or Issued in Certain  Transactions.  The contingent
deferred  sales  charge is also  waived  on Class B and  Class C shares  sold or
issued in the following cases:

     o shares sold to the Manager or its affiliates; o shares sold to registered
management  investment  companies or separate  accounts of  insurance  companies
having an agreement with the Manager or the Distributor  for that purpose;  or o
shares issued in plans of reorganization to which the Fund is a party.

or by  telephone.  You can also set up an  Automatic  Withdrawal  Plan to redeem
shares on a regular basis,  as described  above. If you have questions about any
of these  procedures,  and  especially if you are redeeming  shares in a special
situation, such as due to the death of the owner, please call the Transfer Agent
first, at 1-800-525- 7048, for assistance.
    

      o Certain Requests Require a Signature  Guarantee.  To protect you and the
Fund from fraud, certain redemption requests must be in writing and must include
a signature guarantee in the following situations (there may be other situations
also requiring a signature guarantee):

      o You wish to redeem  more than  $50,000  worth of shares and
receive a check
      o The  redemption  check is not  payable to all  shareholders
listed on the account statement
      o The  redemption  check  is  not  sent  to  the  address  of
record on your account statement
      o Shares  are  being  transferred  to a Fund  account  with a
different owner or name
      o Shares  are  redeemed  by  someone  other  than the  owners
(such as an Executor)

     o Where Can I Have My Signature Guaranteed?  The Transfer Agent will accept
a guarantee of your signature by a number of financial institutions,  including:
a U.S. bank, trust company, credit union or savings association, or by a foreign
bank  that has a U.S.  correspondent  bank,  or by a U.S.  registered  dealer or
broker in securities,  municipal  securities or government  securities,  or by a
U.S. national  securities  exchange,  a registered  securities  association or a
clearing agency.  If you are signing on behalf of a corporation,  partnership or
other  business  or as a  fiduciary,  you must also  include  your  title in the
signature.

Selling  Shares by Mail.  Write a  "letter  of  instructions"  that
includes:

      o Your name
      o The Fund's name
      o Your Fund  account  number  (from your  account  statement) o The dollar
      amount  or  number  of  shares  to  be  redeemed  o  Any  special  payment
      instructions o Any share certificates for the shares you are selling,
and
      o The  signatures  of all  registered  owners  exactly as the
account is registered, and
      o Any special  requirements  or  documents  requested  by the
Transfer  Agent  to  assure  proper  authorization  of  the  person
asking
to sell shares.

Selling Shares by Telephone.  You and your dealer  representative  of record may
also sell your shares by telephone. To receive the redemption price on a regular
business day,  your call must be received by the Transfer  Agent by the close of
The New York Stock Exchange that day, which is normally 4:00 P.M., but which may
be  earlier  on  some  days.  You  may  not  redeem  shares  held  under a share
certificate by telephone.
    

      o To redeem  shares  through a service  representative,  call
1-
800-852-8457.
      o  To  redeem  shares   automatically   on  PhoneLink,   call
1-800-533-
3310.

      Whichever  method you use, you may have a check sent to the address on the
account statement, or, if you have linked your Fund account to your bank account
on AccountLink, you may have the
proceeds sent to that account.

   
      o Telephone  Redemptions  Paid by Check.  Up to $50,000 may be redeemed by
telephone in any 7-day period. The check must be payable to all owners of record
of the shares and must be sent to the  address on the  account  statement.  This
service is not available within 30 days of changing the address on an account.
    

      o  Telephone  Redemptions  Through  AccountLink  or by Wire.  There are no
dollar limits on telephone redemption proceeds sent to a bank account designated
when you  establish  AccountLink.  Normally  the ACH  transfer  to your  bank is
initiated on the business day after the redemption. You do not receive dividends
on the  proceeds  of the  shares  you  redeemed  while  they are  waiting  to be
transferred.

   
      Shareholders may also have the Transfer Agent send redemption  proceeds of
$2,500 or more by Federal  Funds wire to a designated  commercial  bank account.
The bank must be a member of the Federal Reserve wire system. There is a $10 fee
for each  Federal  Funds  wire.  To place a wire  redemption  request,  call the
Transfer Agent at  1-800-852-8457.  The wire will normally be transmitted on the
next bank  business day after the shares are  redeemed.  There is a  possibility
that  the wire  may be  delayed  up to  seven  days to  enable  the Fund to sell
securities to pay the redemption  proceeds.  No dividends are accrued or paid on
the proceeds of shares that have been redeemed and are awaiting  transmittal  by
wire.  To establish  wire  redemption  privileges  on an account that is already
established, please contact the Transfer Agent for instructions.

Selling Shares Through Your Dealer.  The  Distributor  has made  arrangements to
repurchase  Fund shares from  dealers and brokers on behalf of their  customers.
Brokers  or  dealers  may  charge for that  service.  Please  refer to  "Special
Arrangements for Repurchase of Shares from Dealers and Brokers" in the Statement
of Additional Information for more details.
    

Selling  Shares by Wire. You may request that  redemption  proceeds of $2,500 or
more be wired to a previously  designated account at a commercial bank that is a
member of the Federal Reserve wire system. The wire will normally be transmitted
on the next bank business day after the  redemption  of shares.  To place a wire
redemption request, call the Transfer Agent at 1-800-525-7048.
There is a $10 fee for each wire.

Checkwriting.  To be able to write  checks  against your Fund  account,  you may
request  that  privilege  on your  account  Application  or you can  contact the
Transfer  Agent for  signature  cards,  which must be signed  (with a  signature
guarantee)  by all owners of the account and returned to the  Transfer  Agent so
that  checks can be sent to you to use.  Shareholders  with joint  accounts  can
elect in writing to have checks  paid over the  signature  of one owner.  If you
previously  signed  a  signature  card  to  establish  checkwriting  in  another
Oppenheimer  fund,  simply call  1-800-525-7048  to request  checkwriting for an
account in this Fund with the same  registration  as the  previous  checkwriting
account.

      o Checks can be written to the order of whomever you wish,  but may not be
cashed at the Fund's bank or custodian.

      o Checkwriting  privileges are not available for accounts  holding Class B
shares or Class C shares,  or Class A shares  that are  subject to a  contingent
deferred sales charge.

      o Checks must be written for at least $100.

      o Checks  cannot  be paid if they are  written  for more than
your account  value.  Remember:  your  shares  fluctuate  in  value
and you  should  not  write  a check  close  to the  total  account
value.

      o You may not write a check that would  require the Fund to redeem  shares
that were purchased by check or Asset Builder Plan payments  within the prior 10
days.

      o Don't use your  checks  if you  changed  your Fund  account
number.

       
How to Exchange Shares

      Shares of the Fund may be  exchanged  for  shares of  certain  Oppenheimer
funds at net  asset  value  per  share at the time of  exchange,  without  sales
charge. To exchange shares, you must meet
several conditions:

      o  Shares  of  the  fund   selected  for  exchange   must  be
available for sale in your state of residence
      o The  prospectuses  of this Fund and the fund  whose  shares
you want to buy must offer the exchange privilege
      o You must hold the shares you buy when you establish  your account for at
least 7 days before you can exchange them; after the account is open 7 days, you
can exchange shares every regular business day
      o You must meet the  minimum  purchase  requirements  for the
fund you purchase by exchange
      o  Before  exchanging  into a fund,  you  should  obtain  and
read its prospectus

   
      Shares of a particular  class of the Fund may be exchanged only for shares
of the same class in the other Oppenheimer funds. For example,  you can exchange
Class A shares of this Fund only for Class A shares of another fund. At present,
Oppenheimer  Money Market Fund,  Inc.  offers only one class of shares which are
considered to be Class A shares for this purpose.  In some cases,  sales charges
may be  imposed  on  exchange  transactions.  Please  refer to "How to  Exchange
Shares" in the Statement of Additional Information for more details.
    

      Exchanges may be requested in writing or by telephone:

     o Written Exchange Requests.  Submit an  OppenheimerFunds  Exchange Request
form, signed by all owners of the account.  Send it to the Transfer Agent at the
addresses listed in "How to Sell Shares."

     o Telephone  Exchange  Requests.  Telephone  exchange  requests may be made
either by  calling  a  service  representative  at  1-800-852-  8457 or by using
PhoneLink  for  automated  exchanges,  by  calling  1-  800-533-3310.  Telephone
exchanges may be made only between  accounts that are  registered  with the same
name(s) and  address.  Shares held under  certificates  may not be  exchanged by
telephone.

     You can find a list of Oppenheimer funds currently  available for exchanges
in the  Statement of Additional  Information  or obtain one by calling a service
representative at 1-800-525-7048. That list can change from time to time.

      There are certain exchange policies you should be aware of:

      o Shares are normally  redeemed from one fund and purchased from the other
fund in the exchange  transaction on the same regular  business day on which the
Transfer Agent receives an exchange  request that is in proper form by the close
of The New York Stock Exchange that day, which is normally 4:00 P.M., but may be
earlier on some days.  However,  either fund may delay the purchase of shares of
the fund you are  exchanging  into up to seven days if it determines it would be
disadvantaged by a same-day transfer of the proceeds to buy shares. For example,
the receipt of multiple  exchange  requests  from a dealer in a  "market-timing"
strategy  might  require  the sale of  portfolio  securities  at a time or price
disadvantageous to the Fund.

      o  Because   excessive   trading  can  hurt  fund   performance  and  harm
shareholders,  the Fund  reserves the right to refuse any exchange  request that
will disadvantage it, or to refuse multiple exchange
requests submitted by a shareholder or dealer.

     o The Fund may amend,  suspend or terminate  the exchange  privilege at any
time.  Although  the Fund will  attempt to provide  you  notice  whenever  it is
reasonably able to do so, it may impose these changes at any time.

      o For tax purposes, exchanges of shares involve a redemption of the shares
of the fund you own and a purchase  of the shares of the other  Fund,  which may
result in a capital gain or loss.  For more  information  about taxes  affecting
exchanges,  please  refer  to "How  to  Exchange  Shares"  in the  Statement  of
Additional Information.

      o If the Transfer Agent cannot exchange all the shares you request because
of a  restriction  cited above,  only the shares  eligible for exchange  will be
exchanged.

Shareholder Account Rules and Policies

      o Net Asset Value Per Share is  determined  for each class of shares as of
the close of The New York Stock  Exchange,  which is normally 4:00 P.M., but may
be earlier on some days,  on each day the Exchange is open by dividing the value
of the Fund's net assets attributable to a class by the number of shares of that
class that are  outstanding.  The  Trust's  Board of  Trustees  has  established
procedures  to value the Fund's  securities  to determine  net asset  value.  In
general,  securities  values  are  based on  market  value.  There  are  special
procedures for valuing  illiquid and restricted  securities and  obligations for
which market values cannot be readily  obtained.  These procedures are described
more completely in the Statement of Additional Information.

      o The offering of shares may be  suspended  during any period in which the
determination of net asset value is suspended, and the offering may be suspended
by the Board of Trustees at any time the Board believes it is in the Fund's best
interest to do so.

      o Telephone Transaction Privileges for purchases, redemptions or exchanges
may be modified,  suspended or terminated by the Fund at any time. If an account
has  more  than one  owner,  the Fund  and the  Transfer  Agent  may rely on the
instructions of any one owner.  Telephone  privileges apply to each owner of the
account and the dealer representative of record for the account unless and until
the  Transfer  Agent  receives  cancellation  instructions  from an owner of the
account.

      o The  Transfer  Agent will  record  any  telephone  calls to verify  data
concerning  transactions  and has  adopted  other  procedures  to  confirm  that
telephone  instructions  are  genuine,  by  requiring  callers  to  provide  tax
identification  numbers  and  other  account  data  or by  using  PINs,  and  by
confirming  such  transactions  in writing.  If the Transfer  Agent does not use
reasonable   procedures  it  may  be  liable  for  losses  due  to  unauthorized
transactions,  but  otherwise  neither the  Transfer  Agent nor the Fund will be
liable for losses or expenses arising out of telephone  instructions  reasonably
believed to be genuine.  If you are unable to reach the  Transfer  Agent  during
periods of unusual market activity,  you may not be able to complete a telephone
transaction and should consider placing your order by mail.

      o Redemption  or transfer  requests will not be honored until the Transfer
Agent  receives all required  documents in proper form.  From time to time,  the
Transfer  Agent in its  discretion  may waive  certain of the  requirements  for
redemptions stated in this
Prospectus.

      o Dealers  that can  perform  account  transactions  for their  clients by
participating in NETWORKING through the National Securities Clearing Corporation
are  responsible  for  obtaining  their  clients'  permission  to perform  those
transactions  and are  responsible to their clients who are  shareholders of the
Fund if the dealer performs any transaction erroneously or improperly.

      o The  redemption  price for shares  will vary from day to day because the
value of the securities in the Fund's portfolio  fluctuates,  and the redemption
price,  which is the net asset value per share,  will  normally be different for
Class A, Class B and Class C shares.  Therefore,  the  redemption  value of your
shares may be more or less than their original cost.

   
      o Payment for redeemed  shares is made ordinarily in cash and forwarded by
check or through AccountLink (as elected by the shareholder under the redemption
procedures  described above) within seven days after the Transfer Agent receives
redemption  instructions  in proper  form,  except under  unusual  circumstances
determined by the Securities and Exchange Commission delaying or suspending such
payments.  For accounts registered in the name of a broker-dealer,  payment will
be forwarded within three business days. The Transfer Agent may delay forwarding
a check or processing a payment via AccountLink for recently  purchased  shares,
but only until the purchase payment has cleared. That delay may be as much as 10
days from the date the shares were  purchased.  That delay may be avoided if you
purchase shares by federal funds wire, certified check or arrange with your bank
to  provide  telephone  or written  assurance  to the  Transfer  Agent that your
purchase payment has cleared.
    

      o Involuntary redemptions of small accounts may be made by the Fund if the
account  value has fallen  below $200 for  reasons  other than the fact that the
market value of shares has dropped, and in some cases,  involuntary  redemptions
may be made to repay the Distributor  for losses from the  cancellation of share
purchase orders.

      o Under  unusual  circumstances,  shares of the Fund may be  redeemed  "in
kind," which means that the  redemption  proceeds  will be paid with  securities
from the Fund's portfolio. Please refer to "How to Sell Shares" in the Statement
of Additional Information for more details.

   
      o "Backup Withholding" of Federal income tax may be applied at the rate of
31% from taxable  dividends,  distributions and redemption  proceeds  (including
exchanges)  if you fail to furnish  the Fund a current  and  properly  certified
Social   Security  or  Employer   Identification   Number  when  you  sign  your
application, or if you underreport your income to the Internal Revenue Service .
    

      o The Fund does not charge a redemption  fee, but if your dealer or broker
handles  your  redemption,  they may  charge a fee.  That fee can be  avoided by
redeeming  your Fund shares  directly  through  the  Transfer  Agent.  Under the
circumstances  described  in  "How  To Buy  Shares,"  you  may be  subject  to a
contingent  deferred  sales charge when  redeeming  certain Class A, Class B and
Class C shares.

      o To avoid sending  duplicate copies of materials to households,  the Fund
will mail only one copy of each annual and  semi-annual  report to  shareholders
having  the same last name and  address  on the Fund's  records.  However,  each
shareholder may call the Transfer Agent at  1-800-525-7048 to ask that copies of
those materials be sent personally to that shareholder.

Dividends, Capital Gains and Taxes

Dividends. The Fund declares dividends separately for Class A, Class B and Class
C shares from net  investment  income each  regular  business day and pays those
dividends to  shareholders  monthly on a date selected by the Board of Trustees.
Dividends  paid on Class A shares  generally  are expected to be higher than for
Class B or Class C shares  because  expenses  allocable  to Class B and  Class C
shares will generally be higher.

   
     During the Fund's fiscal year ended  September 30, 1997, the Fund attempted
to pay  dividends  on its  Class A shares  at a  targeted  level  above  3-month
Treasury bill rates,  to the extent that was  consistent  with the amount of net
investment  income  and other  distributable  income  available  from the Fund's
portfolio investments.  However, the targeted level can change and the amount of
each  dividend can change from time to time (or there might not be a dividend at
all on any class) depending on market conditions,  the Fund's expenses,  and the
composition of the Fund's  portfolio.  Attempting to pay dividends at a targeted
level  required  the  Manager  to  monitor  the Fund's  income  stream  from its
investments  compared  to  Treasury  bill  rates and at times to  select  higher
yielding  securities  (appropriate  to  the  Fund's  investment  objectives  and
restrictions) to try to earn income at the targeted level. This practice did not
affect  the net  asset  values  of any  class of  shares.  There is no  targeted
dividend  level for Class B or Class C shares.  There is no fixed  dividend rate
and there can be no assurance as to payment of any dividends.
    

     Capital Gains.  Although the Fund does not seek capital gains, the Fund may
realize  capital gains on the sale of portfolio  securities.  If it does, it may
make  distributions  annually in December out of any net short-term or long-term
capital gains.  The Fund may also make  supplemental  distributions of dividends
and capital gains  following  the end of its fiscal year. If net capital  losses
are realized in any year, they are charged against the principal and not against
net  investment  income,  which is  distributed  regardless  of capital gains or
losses.  Long-term  capital  gains  will  be  separately  identified  in the tax
information  the Fund sends you after the end of the calendar  year.  Short-term
capital gains are treated as dividends for tax purposes.

     Distribution  Options.  When  you  open  your  account,   specify  on  your
application how you want to receive your distributions. You have four options:

     o Reinvest  All  Distributions  in the Fund.  You can elect to reinvest all
dividends and long-term capital gains  distributions in additional shares of the
Fund.  o Reinvest  Capital  Gains  Only.  You can elect to  reinvest  long- term
capital  gains in the Fund while  receiving  dividends  by check or sent to your
bank account on AccountLink.  o Receive All Distributions in Cash. You can elect
to receive a check for all dividends and long-term  capital gains  distributions
or have them sent to your bank on AccountLink.
   

     o Reinvest Your Distributions in Another Oppenheimer Funds Account. You can
reinvest all  distributions  in the same class of shares of another  Oppenheimer
fund account you have established.

Taxes.  Long-term  capital  gains are taxable as  long-term  capital  gains when
distributed to  shareholders.  It does not matter how long you held your shares.
Dividends  paid from  short-term  capital gains are taxable as ordinary  income.
Dividends  paid  from net  investment  income  earned  by the Fund on  Municipal
Securities  will be  excludable  from your gross  income for Federal  income tax
purposes.  A  portion  of the  dividends  paid by the Fund may be an item of tax
preference if you are subject to alternative  minimum tax. Taxable dividends and
distributions  are subject to federal  income tax and may be subject to state or
local taxes.  Whether you reinvest your  distributions  in additional  shares or
take them in cash, the tax treatment is the same.  Every year the Fund will send
you and the IRS a statement  showing the amount of any taxable  distribution you
received in the previous year as well as the amount of your  tax-exempt  income.
So that  the Fund  will not have to pay  taxes  on  amounts  it  distributes  to
shareholders  as  dividends  and capital  gains,  the Fund intends to manage its
investments  so that it will qualify as a "regulated  investment  company" under
the Internal  Revenue  Code,  although it reserves the right not to qualify in a
particular year.

      o "Buying  a  Dividend":  If you buy  shares  on or just  before  the Fund
declares  a  capital  gains  distribution,  you will pay the full  price for the
shares and then receive a portion of the price back as a taxable  capital  gain.
To the extent the Fund's dividends include taxable income, you will pay taxes on
that portion of the dividend.
    

      o Taxes on Transactions:  Even though the Fund seeks tax-exempt income for
distribution to shareholders,  you may have a capital gain or loss when you sell
or exchange your shares.  A capital gain or loss is the  difference  between the
price you paid for the shares and the price you received when you sold them. Any
capital gain is subject to capital gains tax.

      o Returns of Capital: In certain cases, distributions made by the Fund may
be considered a non-taxable  return of capital to shareholders.  If that occurs,
it will be  identified  in  notices to  shareholders.  A  non-taxable  return of
capital may reduce your tax basis in your Fund shares.

   
      This  information  is only a summary of certain  federal  tax  information
about your  investment.  More  information  is  contained  in the  Statement  of
Additional Information, and in addition you should consult with your tax advisor
about the effect of an investment in the Fund on your particular tax situation.

                            APPENDIX A

  Special Sales Charge Arrangements for Shareholders of the Fund
    Who Were Shareholders of the Former Quest for Value Funds

   
      The initial and  contingent  deferred  sales  charge rates and waivers for
Class A,  Class B and Class C shares  of the Fund  described  elsewhere  in this
Prospectus  are  modified  as  described  below  for those  shareholders  of (i)
Oppenheimer  Quest Value Fund,  Inc.,  Oppenheimer  Quest  Growth & Income Fund,
Oppenheimer Quest Opportunity Value Fund, Oppenheimer Quest Small Cap value Fund
and  Oppenheimer  Quest  Global  Value Fund,  Inc. on November  24,  1995,  when
OppenheimerFunds,  Inc. became the investment  advisor to those funds,  and (ii)
Quest for Value U.S.  Government Income Fund, Quest for Value Investment Quality
Income  Fund,  Quest  for Value  Global  Income  Fund,  Quest for Value New York
Tax-Exempt  Fund,  Quest for Value National  Tax-Exempt Fund and Quest for Value
California  Tax- Exempt Fund when those funds  merged into  various  Oppenheimer
funds on November  24,  1995.  The funds  listed  above are  referred to in this
Prospectus  as the  "Former  Quest for Value  Funds." The waivers of initial and
contingent  deferred sales charges described in this Appendix apply to shares of
the Fund (i) acquired by such  shareholder  pursuant to an exchange of shares of
one of the Oppenheimer funds that was one of the Former Quest for Value Funds or
(ii) purchased by such  shareholder  by exchange of shares of other  Oppenheimer
funds that were  acquired  pursuant to the merger of any of the Former Quest for
Value Funds into an Oppenheimer fund on November 24, 1995.
    

Class A Sales Charges

o Reduced  Class A Initial  Sales Charge  Rates for Certain  Former
Quest Shareholders

o  Purchases  by Groups and  Associations.  The  following  table sets forth the
initial  sales  charge  rates  for  Class  A  shares  purchased  by  members  of
"Associations"  formed for any purpose  other than the purchase of securities if
that Association  purchased shares of any of the Former Quest for Value Funds or
received a proposal to  purchase  such  shares  from OCC  Distributors  prior to
November 24, 1995.

      For  purchases by  Associations  having 50 or more  eligible  employees or
members,  there is no initial  sales charge on purchases of Class A shares,  but
those  shares  are  subject  to the Class A  contingent  deferred  sales  charge
described on page __ of this
Prospectus.

      Purchases made under this  arrangement  qualify for the lower of the sales
charge rate in the table based on the number of members of an Association or the
sales charge rate that applies under the Rights of Accumulation  described above
in the Prospectus.  Individuals  who qualify under this  arrangement for reduced
sales charge rates as members of Associations also may purchase shares for their
individual  or custodial  accounts at these  reduced  sales charge  rates,  upon
request to the Fund's Distributor.

       
o  Waiver of Class A Sales Charges for Certain Shareholders

Class A shares of the Fund purchased by the following  investors are not subject
to any Class A initial or contingent deferred sales
charges:

      o  Shareholders  of the Fund who were  shareholders  of the AMA  Family of
Funds on February  28, 1991 and who  acquired  shares of any of the Former Quest
for Value Funds by merger of a portfolio of the
AMA Family of Funds.

      o  Shareholders  of the Fund who  acquired  shares of any Former Quest for
Value Fund by merger of any of the portfolios of the Unified Funds.

o  Waiver  of  Class  A   Contingent   Deferred   Sales  Charge  in
Certain Transactions

The Class A contingent  deferred  sales charge will not apply to  redemptions of
Class A  shares  of the  Fund  purchased  by the  following  investors  who were
shareholders of any Former Quest for Value Fund:

      o Investors who purchased  Class A shares from a dealer that is or was not
permitted  to receive a sales load or  redemption  fee imposed on a  shareholder
with whom that dealer has a fiduciary relationship under the Employee Retirement
Income Security Act of 1974 and regulations adopted under that law.

Class A,  Class B and  Class C  Contingent  Deferred  Sales  Charge
Waivers

o  Waivers  for  Redemptions  of  Shares  Purchased  Prior to March
6, 1995

In the following cases, the contingent  deferred sales charge will be waived for
redemptions  of Class A, Class B or Class C shares of the Fund  acquired  by the
merger of a Former  Quest for Value  Fund into the Fund or by  exchange  from an
Oppenheimer  fund that was a Former Quest for Value Fund or into which such fund
merged, if those shares were purchased prior to March 6, 1995 in connection with
(i) withdrawals  under an automatic  withdrawal plan holding only either Class B
or Class C shares if the annual  withdrawal  does not exceed 10% of the  initial
value of the account,  and (ii)  liquidation of a  shareholder's  account if the
aggregate  net  asset  value of  shares  held in the  account  is less  than the
required minimum value of such accounts.

o  Waivers  for  Redemptions  of  Shares   Purchased  on  or  After
March 6, 1995 but Prior to November 24, 1995.

In the following cases, the contingent  deferred sales charge will be waived for
redemptions  of Class A, Class B or Class C shares of the Fund  acquired  by the
merger of a Former  Quest for Value  Fund into the Fund or by  exchange  from an
Oppenheimer  fund that was a Former Quest For Value Fund or into which such fund
merged,  if those shares were  purchased on or after March 6, 1995, but prior to
November 24, 1995:  (1)  redemptions  following  the death or  disability of the
shareholder(s)  (as evidenced by a determination of total disability by the U.S.
Social Security  Administration);  (2) withdrawals under an automatic withdrawal
plan (but only for Class B or Class C shares)  where the annual  withdrawals  do
not exceed 10% of the initial  value of the account;  and (3)  liquidation  of a
shareholder's  account if the  aggregate  net asset  value of shares held in the
account is less than the required minimum account value. A shareholder's account
will be credited with the amount of any contingent deferred sales charge paid on
the  redemption of any Class A, Class B or Class C shares of the Fund  described
in this  section if within 90 days  after  that  redemption,  the  proceeds  are
invested in the same Class of shares in this Fund or another Oppenheimer fund.

ABOUT THE FUND

Investment Objective and Policies

   
Investment Policies and Strategies. The investment objective and policies of the
Fund  are  described  in  the  Prospectus.   Set  forth  below  is  supplemental
information  about those  policies and the types of securities in which the Fund
may  invest,  as well as the  strategies  the Fund may use to try to achieve its
objective.  Certain  capitalized  terms  used in this  Statement  of  Additional
Information have the same meaning as those terms have in the Prospectus.
    

Municipal  Securities.  There  are  variations  in  the  security  of  Municipal
Securities, both within a particular classification and between classifications,
depending on numerous  factors.  The yields of Municipal  Securities  depend on,
among other things,  general conditions of the Municipal Securities market, size
of a  particular  offering,  the  maturity of the  obligation  and rating of the
issue.  The  market  value of  Municipal  Securities  will  vary as a result  of
changing  evaluations  of the  ability  of their  issuers to meet  interest  and
principal  payments,  as well as changes in the  interest  rates  payable on new
issues of Municipal Securities.

     o Municipal Bonds.  The principal  classifications  of long-term  municipal
bonds are "general obligation" and "revenue" or "industrial development" bonds.

       o General  Obligation Bonds.  Issuers of general obligation bonds include
states,  counties,  cities, towns, and regional districts. The proceeds of these
obligations  are  used  to  fund a wide  range  of  public  projects,  including
construction or improvement of schools,  highways and roads, and water and sewer
systems.  The basic  security  behind general  obligation  bonds is the issuer's
pledge  of its full  faith and  credit  and  taxing  power  for the  payment  of
principal  and  interest.  The taxes that can be levied for the  payment of debt
service  may be  limited  or  unlimited  as to the  rate or  amount  of  special
assessments.

     o Revenue Bonds. The principal security for a revenue bond is generally the
net revenues  derived from a particular  facility,  group of facilities,  or, in
some cases,  the proceeds of a special excise or other specific  revenue source.
Revenue  bonds  are  issued  to  finance  a wide  variety  of  capital  projects
including:  electric,  gas,  water and sewer  systems;  highways,  bridges,  and
tunnels; port and airport facilities;  colleges and universities; and hospitals.
Although  the  principal  security  behind  these bonds may vary,  many  provide
additional  security in the form of a debt service  reserve fund whose money may
be used to make  principal  and interest  payments on the issuer's  obligations.
Housing finance  authorities have a wide range of security,  including partially
or fully insured  mortgages,  rent subsidized and/or  collateralized  mortgages,
and/or the net revenues from housing or other public projects.  Some authorities
provide further security in the form of a state's ability  (without  obligation)
to make up deficiencies in the debt service reserve fund.

     o Industrial  Development  Bonds.  Industrial  development bonds, which are
considered  municipal  bonds if the interest paid is exempt from federal  income
tax, are issued by or on behalf of public  authorities to raise money to finance
various privately operated  facilities for business and manufacturing,  housing,
sports,  and  pollution  control.  These  bonds are also used to finance  public
facilities  such as airports,  mass transit  systems,  ports,  and parking.  The
payment of the principal  and interest on such bonds is dependent  solely on the
ability of the facility's user to meet its financial obligations and the pledge,
if any, of real and personal property so financed as security for such payment.


     o Municipal Notes.  Municipal  Securities  having a maturity when issued of
less than one year are  generally  known as  municipal  notes.  Municipal  notes
generally are used to provide for short-term working capital needs and include:

       o Tax Anticipation  Notes.  Tax anticipation  notes are issued to finance
working  capital  needs  of  municipalities.   Generally,  they  are  issued  in
anticipation  of various  seasonal tax revenue,  such as income,  sales,  use or
business taxes, and are payable from these specific future taxes.

     o Revenue  Anticipation  Notes.  Revenue  anticipation  notes are issued in
expectation  of  receipt of other  types of  revenue,  such as Federal  revenues
available under the Federal revenue sharing programs.

     o Bond Anticipation  Notes.  Bond anticipation  notes are issued to provide
interim financing until long-term financing can be arranged.  In most cases, the
long-term bonds then provide the money for the repayment of the notes.

     o  Construction  Loan  Notes.  Construction  loan notes are sold to provide
construction  financing.  After  successful  completion  and  acceptance,   many
projects receive permanent financing through the Federal Housing Administration.

    o Tax-Exempt  Commercial Paper.  Tax-exempt commercial paper is a short-term
obligation with a stated maturity of 365 days or less. It is issued by state and
local governments or their agencies to finance seasonal working capital needs or
as short-term financing in anticipation of longer-term financing.

    o Floating  Rate/Variable Rate Obligations.  Floating rate and variable rate
demand  notes are  tax-exempt  obligations  which may have a stated  maturity in
excess of one year,  but may include  features that permit the holder to recover
the  principal  amount of the  underlying  security at specified  intervals  not
exceeding  one year and upon no more than 30 days'  notice.  The  issuer of such
notes normally has a corresponding right, after a given period, to prepay in its
discretion the outstanding  principal  amount of the note plus accrued  interest
upon a specified  number of days notice to the holder.  The  interest  rate on a
floating rate demand note is based on a stated prevailing market rate, such as a
bank's prime rate, the 90-day U.S.  Treasury Bill rate, or some other  standard,
and is adjusted automatically each time such rate is adjusted. The interest rate
on a variable rate demand note is also based on a stated  prevailing market rate
but is adjusted  automatically at specified  intervals of no more than one year.
Generally,  the  changes  in the  interest  rate on such  securities  reduce the
fluctuation in their market value.  As interest rates decrease or increase,  the
potential  for  capital  appreciation  or  depreciation  is less  than  that for
fixed-rate  obligations of the same maturity.  The Trust's  investment  adviser,
OppenheimerFunds,  Inc. (the "Manager"),  may determine that an unrated floating
rate or variable rate demand  obligation  meets the Fund's quality  standards by
reason of being backed by a letter of credit or guarantee  issued by a bank that
meets the Fund's quality standards.

    |X| Inverse Floaters and Other Derivative Investments. Some inverse floaters
have a  feature  known as an  interest  rate  "cap" as part of the  terms of the
investment.  Investing in inverse floaters that have interest rate caps might be
part of a portfolio  strategy to try to  maintain a high  current  yield for the
Fund when the Fund has invested in inverse  floaters that expose the Fund to the
risk of short-term  interest rate fluctuation.  Embedded caps hedge a portion of
the Fund's  exposure to rising  interest  rates.  When interest rates exceed the
pre-determined  rate,  the cap generates  additional  cash flows that offset the
decline in interest rates on the inverse  floater,  and the hedge is successful.
However,  the Fund bears the risk that if  interest  rates do not rise above the
pre-determined  rate, the cap (which is purchased for additional  cost) will not
provide additional cash flows and will expire worthless.

    |X| Municipal Lease Obligations.  From time to time the Fund may invest more
than 5% of its net assets in municipal lease obligations,  generally through the
acquisition of certificates of participation, that the Manager has determined to
be liquid  under  guidelines  set by the  Board of  Trustees.  Those  guidelines
require  the  Manager  to  evaluate:  (1) the  frequency  of  trades  and  price
quotations  for such  securities;  (2) the number of dealers or other  potential
buyers  willing to purchase or sell such  securities;  (3) the  availability  of
market-makers; and (4) the nature of the trades for such securities. The Manager
will also  evaluate the  likelihood of a continuing  market for such  securities
throughout  the time  they are held by the Fund and the  credit  quality  of the
instrument.  Municipal  leases  may take  the form of a lease or an  installment
purchase  contract  issued by a state or local  government  authority  to obtain
funds to acquire a wide  variety of equipment  and  facilities.  Although  lease
obligations do not constitute general  obligations of the municipality for which
the  municipality's  taxing power is pledged,  a lease  obligation is ordinarily
backed by the  municipality's  covenant to budget for,  appropriate and make the
payments due under the lease  obligation.  However,  certain  lease  obligations
contain  "non-appropriation"  clauses which provide that the municipality has no
obligation to make lease or installment purchase payments in future years unless
money is appropriated for such purpose on a yearly basis. Projects financed with
certificates of participation  generally are not subject to state constitutional
debt  limitations  or other  statutory  requirements  that may be  applicable to
Municipal Securities. Payments by the public entity on the obligation underlying
the certificates are derived from available revenue sources; such revenue may be
diverted  to the  funding  of other  municipal  service  projects.  Payments  of
interest and/or  principal with respect to the  certificates  are not guaranteed
and do not  constitute an obligation of the issuing  municipality  or any of its
political subdivisions.

    In addition to the risk of  "non-appropriation,"  municipal lease securities
do not yet have a highly  developed market to provide the degree of liquidity of
conventional  municipal  bonds.  Municipal  leases,  like other  municipal  debt
obligations,  are subject to the risk of non-payment.  The ability of issuers of
municipal  leases to make timely lease  payments  may be  adversely  affected in
general  economic  downturns  and as  relative  governmental  cost  burdens  are
reallocated among federal,  state and local governmental units. Such non-payment
would  result  in a  reduction  of income  to the  Fund,  and could  result in a
reduction in the value of the municipal  lease  experiencing  non-payment  and a
potential decrease in the net asset value of the Fund.

    o Private  Activity  Municipal  Securities.  The Tax Reform Act of 1986 (the
"Tax Reform  Act")  reorganized,  as well as amended,  the rules  governing  tax
exemption  for interest on Municipal  Securities.  The Tax Reform Act  generally
does not  change  the tax  treatment  of bonds  issued to  finance  governmental
operations.  Thus,  interest on obligations issued by or on behalf of a state or
local  government,  the proceeds of which are used to finance the  operations of
such governments  (e.g.,  general  obligation bonds) continues to be tax-exempt.
However,  the Tax Reform Act  further  limited the use of  tax-exempt  bonds for
non-governmental  (private) purposes. More stringent restrictions were placed on
the use of proceeds of such bonds.  Interest on certain  private  activity bonds
(other than those specified as "qualified"  tax-exempt  private  activity bonds,
e.g.,  exempt facility bonds including  certain  industrial  development  bonds,
qualified mortgage bonds,  qualified Section 501(c)(3) bonds,  qualified student
loan bonds, etc.) is taxable under the revised rules.

    Interest on certain  private  activity  bonds  issued  after August 7, 1986,
which  continues  to be  tax-exempt  will be  treated as a tax  preference  item
subject  to the  alternative  minimum  tax  (discussed  below) to which  certain
taxpayers  are  subject.  Furthermore,  a  private  activity  bond  which  would
otherwise  be a  qualified  tax-exempt  private  activity  bond will not,  under
Internal Revenue Code Section 147(a),  be a qualified bond for any period during
which it is held by a person who is a "substantial user" of the facilities or by
a "related person" of such a substantial user. This "substantial user" provision
is  applicable   primarily  to  exempt  facility  bonds,   including  industrial
development  bonds.  The Fund may not be an appropriate  investment for entities
which are  "substantial  users" (or  persons  related  thereto)  of such  exempt
facilities,  and such  persons  should  consult  their own tax  advisers  before
purchasing  shares. A "substantial user" of such facilities is defined generally
as a "non-exempt person who regularly uses part of a facility" financed from the
proceeds  of exempt  facility  bonds.  Generally,  an  individual  will not be a
"related  person"  under the Internal  Revenue Code unless such  investor or the
investor's   immediate   family   (spouse,   brothers,   sisters  and  immediate
descendants)  own directly or indirectly in the aggregate more than 50% in value
of the equity of a corporation or partnership which is a "substantial user" of a
facility  financed  from the  proceeds of exempt  facility  bonds.  In addition,
limitations  as to the amount of  private  activity  bonds  which each state may
issue were revised  downward by the Tax Reform Act, which will reduce the supply
of such bonds. The value of the Fund's portfolio could be affected if there is a
reduction in the availability of such bonds.  That value may also be affected by
a 1988 U.S.  Supreme  Court  decision  upholding  the  constitutionality  of the
imposition  of a Federal  tax on the  interest  earned on  Municipal  Securities
issued in bearer form.

    A Municipal  Security is treated as a taxable private  activity bond under a
test for: (a) a trade or business use and  security  interest,  or (b) a private
loan restriction. Under the trade or business use and security interest test, an
obligation is a private activity bond if: (i) more than 10% of bond proceeds are
used for  private  business  purposes  and (ii)  10% or more of the  payment  of
principal or interest on the issue is directly or  indirectly  derived from such
private use or is secured by the privately used property or the payments related
to the use of the  property.  For  certain  types of  uses,  a 5%  threshold  is
substituted for this 10% threshold.  (The term "private  business use" means any
direct or indirect  use in a trade or business  carried on by an  individual  or
entity other than a state or municipal  governmental unit.) Under the test for a
private loan restriction,  the amount of bond proceeds which may be used to make
private  loans is limited to the lesser of 5% or $5.0  million of the  proceeds.
Thus, certain issues of Municipal  Securities could lose their tax-exempt status
retroactively  if the  issuer  fails  to  meet  certain  requirements  as to the
expenditure of the proceeds of that issue or use of the bond-financed  facility.
The Fund  makes no  independent  investigation  of the  issuers of such bonds or
their use of  proceeds.  Should the Fund hold a bond that  loses its  tax-exempt
status  retroactively,  there might be an  adjustment to the  tax-exempt  income
previously paid to shareholders.

    The Federal alternative minimum tax is designed to ensure that all taxpayers
pay some tax, even if their regular tax is zero. This is accomplished in part by
including  in  taxable  income  certain  tax  preference  items in  arriving  at
alternative  minimum taxable income.  The Tax Reform Act, which makes tax-exempt
interest from certain private  activity bonds a tax preference item for purposes
of the  alternative  minimum tax on individuals and  corporations,  specifically
states that any exempt-interest  dividend paid by a regulated investment company
will be treated as interest on a specific private activity bond to the extent of
its proportionate  share of the interest on such bonds received by the regulated
investment company. The Treasury is authorized to issue regulations implementing
the provision. The Fund may hold Municipal Securities the interest on which (and
thus a proportionate  share of the exempt- interest  dividends paid by the Fund)
will be  subject to the  Federal  alternative  minimum  tax on  individuals  and
corporations.

   
    o Ratings  of  Municipal  Securities.  Moody's , S&P's,  Fitch's  and Duff &
Phelps' or other rating  organizations  ratings (See Appendix A) represent their
respective opinions of the quality of the Municipal Securities they undertake to
rate.  However,  such  ratings are general and  subjective  and are not absolute
standards of quality. Consequently, Municipal Securities with the same maturity,
coupon and rating may have different yields,  while Municipal  Securities of the
same  maturity  and  coupon  with  different  ratings  may have the same  yield.
Investment  in  lower-quality   securities  may  produce  a  higher  yield  than
securities rated in the higher rating categories described in the Prospectus (or
judged by the Manager to be of comparable  quality).  However, the added risk of
lower quality  securities  might not be consistent with a policy of preservation
of capital.
    

    o Additional  Information  About  Municipal  Securities.  From time to time,
proposals  have been  introduced  before  Congress to restrict or eliminate  the
Federal  income tax  exemption  for  interest on Municipal  Securities.  Similar
proposals may be introduced in the future. If such a proposal were enacted,  the
availability of Municipal Securities for investment by the Fund and the value of
the portfolio of the Fund would be affected. At such time, the Board of Trustees
of the Trust would  re-evaluate  the  investment  objectives and policies of the
Fund and possibly submit to shareholders  proposals for changes in the structure
of the Fund.

Other Investment Techniques and Strategies

     o Hedging  With  Options  and Futures  Contracts.  The Fund may use hedging
instruments  for the  purposes  described  in the  Prospectus.  When  hedging to
attempt to protect against declines in the market value of the Fund's portfolio,
or to permit  the Fund to  retain  unrealized  gains in the  value of  portfolio
securities  which have  appreciated,  or to facilitate  selling  securities  for
investment  reasons,  the Fund may: (i) sell  Interest Rate Futures or Municipal
Bond Index Futures, (ii) buy puts on such Futures or securities,  or (iii) write
covered calls on securities held by it, Interest Rate Futures, or Municipal Bond
Index  Futures.  When  hedging to  establish a position  in the debt  securities
markets as a temporary substitute for the purchase of individual debt securities
the Fund may: (i) buy Interest Rate Futures or Municipal Bond Index Futures,  or
(ii) buy calls on such Futures or debt securities. Normally, the Fund would then
purchase the debt securities and terminate the hedging position.

    The Fund's  strategy of hedging  with Futures and options on Futures will be
incidental to the Fund's investment activities in the underlying cash market. In
the future, the Fund may employ hedging  instruments and strategies that are not
presently contemplated but which may be developed, to the extent such investment
methods are consistent  with the Fund's  investment  objective,  and are legally
permissible and disclosed in the Prospectus.  Additional  information  about the
hedging instruments the Fund may use is provided below.

     o Writing Covered Calls. As described in the Prospectus, the Fund may write
covered  calls.  When the Fund  writes a call on an  investment,  it  receives a
premium  and  agrees  to  sell  the  callable  investment  to a  purchaser  of a
corresponding  call during the call period (usually not more than 9 months) at a
fixed  exercise  price (which may differ from the market price of the underlying
investment)  regardless  of market  price  changes  during the call  period.  To
terminate  its  obligation  on a call it has  written,  the Fund may  purchase a
corresponding call in a "closing purchase transaction." A profit or loss will be
realized,  depending  upon  whether the net of the amount of option  transaction
costs and the premium  received on the call the Fund has written is more or less
than the price of the call the Fund subsequently purchased. A profit may also be
realized if the call lapses unexercised, because the Fund retains the underlying
investment and the premium  received.  Those profits are  considered  short-term
capital gains for Federal income tax purposes,  as are premiums on lapsed calls,
and when  distributed  by the Fund are taxable as ordinary  income.  If the Fund
could not effect a closing purchase  transaction due to the lack of a market, it
would  have to hold  the  callable  investment  until  the  call  lapsed  or was
exercised.  The Fund will not write covered call options in an amount  exceeding
20% of the value of its total assets.

    The Fund may also write calls on Futures  without owning a futures  contract
or deliverable  securities,  provided that at the time the call is written,  the
Fund covers the call by  segregating  in escrow an  equivalent  dollar  value of
deliverable  securities or liquid  assets.  The Fund will  segregate  additional
liquid  assets if the  value of the  escrowed  assets  drops  below  100% of the
current value of the Future. In no circumstances  would an exercise notice as to
a Future put the Fund in a short futures position.

    The Fund's Custodian,  or a securities  depository acting for the Custodian,
will act as the Fund's  escrow  agent,  through  the  facilities  of the Options
Clearing  Corporation  ("OCC"),  as to the  investments  on  which  the Fund has
written options that are traded on exchanges,  or as to other acceptable  escrow
securities,  so that no margin  will be  required  from the Fund for such option
transactions.  OCC will release the securities covering a call on the expiration
of the call or when the Fund enters into a closing  purchase  transaction.  Call
writing affects the Fund's turnover rate and the brokerage  commissions it pays.
Commissions,  normally  higher  than on  general  securities  transactions,  are
payable on writing or purchasing a call.

     o  Interest  Rate  Futures.  The Fund may buy and  sell  futures  contracts
relating to interest rates  ("Interest Rate Futures") and municipal bond indices
("Municipal Bond Index  Futures").  An Interest Rate Future obligates the seller
to deliver  and the  purchaser  to take a specific  type of debt  security  at a
specific future date for a fixed price to settle the futures transaction,  or to
enter into an offsetting contract. No monetary amount is paid or received by the
Fund on the purchase of an Interest Rate Future.  The Fund may  concurrently buy
and sell Futures  contracts in an attempt to benefit from any  outperformance of
the  Future  purchased  relative  to the  performance  of the Future  sold.  For
example,  the Fund might buy Municipal Bond Futures and sell U.S.  Treasury Bond
Futures  (a type of  Interest  Rate  Future).  This  type of  transaction  would
generally be profitable to the Fund if municipal bonds outperform U.S.  Treasury
bonds after duration has been considered.  Duration is a volatility measure that
refers to the expected percentage change in the value of a bond resulting from a
change in general  interest  rates  (measured  by each 1% change in the rates on
U.S. Treasury  securities).  For example, if a bond has an effective duration of
three years, a 1% increase in general  interest rates would be expected to cause
the bond to decline about 3%. Risks of this type of Futures  transaction,  using
the example above, would include (1) outperformance of U.S.  Treasuries relative
to municipal bonds, on a duration-  adjusted basis,  and (2) duration  mismatch,
with duration of municipal bonds relative to U.S.  Treasuries being greater than
anticipated.

    Upon  entering  into a Futures  transaction,  the Fund will be  required  to
deposit an initial margin  payment,  in cash or U.S.  Treasury  bills,  with the
futures commission merchant (the "futures broker"). Initial margin payments will
be deposited with the Fund's  Custodian in an account  registered in the futures
broker's name; however,  the futures broker can gain access to that account only
under certain specified conditions.  As the Future is marked to market (that is,
its value on the  Fund's  books is  changed)  to  reflect  changes in its market
value,  subsequent margin payments,  called variation margin, will be paid to or
by the futures broker on a daily basis.

     At any time prior to the  expiration  of the Future,  the Fund may elect to
close out its  position  by taking an opposite  position,  at which time a final
determination  of variation margin is made and additional cash is required to be
paid by or released to the Fund.  Any gain or loss is then  realized by the Fund
on the Future for tax  purposes.  Although  Interest  Rate  Futures call for the
delivery of a specific debt security, in most cases the settlement obligation is
fulfilled without such delivery by entering into an offsetting transaction.  All
Futures  transactions  are effected through a clearing house associated with the
exchange on which the contracts are traded.

    o Municipal Bond Index Futures.  A "municipal  bond index" assigns  relative
values to the municipal  bonds  included in that index,  and is used to serve as
the basis for trading long-term municipal bond Futures contracts. Municipal Bond
Index  Futures are similar to Interest  Rate Futures  except that  settlement is
made in cash.  The  obligation  under such  contracts  may also be  satisfied by
entering into an offsetting contract to close out the futures position. Net gain
or loss on options on such  Municipal  Bond Index  Futures  depends on the price
movements of the securities included in the index. The strategies which the Fund
employs  regarding  Municipal Bond Index Futures are similar to those  described
above with regard to Interest Rate Futures.

    o Interest Rate Swap Transactions. Swap agreements entail both interest rate
risk and credit risk. There is a risk that, based on movements of interest rates
in the future,  the payments made by the Fund under a swap  agreement  will have
been greater than those received by it. Credit risk arises from the  possibility
that the counterparty will default. If the counterparty to an interest rate swap
defaults, the Fund's loss will consist of the net amount of contractual interest
payments  that the Fund has not yet  received.  The  Manager  will  monitor  the
creditworthiness of counterparties to the Fund's interest rate swap transactions
on an ongoing basis. The Fund will enter into swap transactions with appropriate
counterparties pursuant to master netting agreements.

    A master netting agreement provides that all swaps done between the Fund and
that  counterparty  under the master  agreement shall be regarded as parts of an
integral  agreement.  If on any date amounts are payable in the same currency in
respect of one or more swap transactions, the net amount payable on that date in
that  currency  shall be paid.  In addition,  the master  netting  agreement may
provide that if one party defaults  generally or on one swap,  the  counterparty
may terminate the swaps with that party.  Under such  agreements,  if there is a
default resulting in a loss to one party, the measure of that party's damages is
calculated by reference to the average cost of a  replacement  swap with respect
to each swap (i.e., the  mark-to-market  value at the time of the termination of
each swap). The gains and losses on all swaps are then netted, and the result is
the counterparty's gain or loss on termination. The termination of all swaps and
the  netting of gains and losses on  termination  is  generally  referred  to as
"aggregation."  The Fund will not invest more than 25% of its assets in interest
rate swap transactions and only on securities it owns.

     o Purchasing Puts and Calls. The Fund may purchase calls to protect against
the possibility that the Fund's portfolio will not participate in an anticipated
rise in the securities  market.  When the Fund purchases a call (other than in a
closing  purchase  transaction),  it pays a premium  and,  except as to calls on
Municipal  Bond Index Futures,  has the right to buy the  underlying  investment
from a seller of a  corresponding  call on the same  investment  during the call
period at a fixed exercise  price.  In purchasing a call, the Fund benefits only
if the call is sold at a profit or if, during the call period,  the market price
of the  underlying  investment  is above the sum of the call price,  transaction
costs,  and the  premium  paid,  and the call is  exercised.  If the call is not
exercised or sold (whether or not at a profit),  it will become worthless at its
expiration  date and the Fund will  lose its  premium  payment  and the right to
purchase  the  underlying  investment.  When  the  Fund  purchases  a call  on a
municipal bond index,  Municipal  Bond Index Future or Interest Rate Future,  it
pays a  premium,  but  settlement  is in cash  rather  than by  delivery  of the
underlying investment to the Fund.

    When the Fund  purchases a put, it pays a premium and,  except as to puts on
municipal  bond indices,  has the right to sell the  underlying  investment to a
seller of a corresponding  put on the same investment during the put period at a
fixed exercise price.  Buying a put on a debt security,  Interest Rate Future or
Municipal Bond Index Future the Fund owns (a "protective  put") enables the Fund
to  attempt  to protect  itself  during the put period  against a decline in the
value of the  underlying  investment  below the  exercise  price by selling  the
underlying  investment at the exercise price to a seller of a corresponding put.
If the  market  price of the  underlying  investment  is  equal to or above  the
exercise price and as a result the put is not exercised or resold,  the put will
become  worthless at its expiration  and the Fund will lose the premium  payment
and the right to sell the underlying  investment.  However,  the put may be sold
prior to expiration (whether or not at a profit).

    An option position may be closed out only on a market which provides trading
for  options  of the  same  series,  and  there  is no  assurance  that a liquid
secondary  market  will  exist for any  particular  option.  The  Fund's  option
activities may affect its portfolio turnover rate and brokerage commissions. The
exercise  of  calls  written  by the  Fund may  cause  the Fund to sell  related
portfolio  securities,  thus  increasing  its turnover rate. The exercise by the
Fund of puts on  securities  will  cause  the  sale of  underlying  investments,
increasing  portfolio turnover.  Although the decision whether to exercise a put
it holds is within the  Fund's  control,  holding a put might  cause the Fund to
sell the related  investments for reasons that would not exist in the absence of
the put. The Fund will pay a brokerage  commission  each time it buys or sells a
call, put or an underlying  investment in connection  with the exercise of a put
or call.  Those  commissions  may be  higher  than the  commissions  for  direct
purchases or sales of the underlying investments.

    Premiums  paid for options are small in relation to the market  value of the
underlying  investments  and,  consequently,  put and call  options  offer large
amounts of leverage.  The leverage offered by trading in options could result in
the Fund's net asset value being more  sensitive  to changes in the value of the
underlying investments.

    o Regulatory Aspects of Hedging Instruments. The Fund is required to operate
within certain  guidelines and  restrictions  with respect to its use of Futures
and options on Futures  established by the Commodity Futures Trading  Commission
("CFTC").  In particular the Fund is exempted from registration with the CFTC as
a "commodity  pool operator" if the Fund complies with the  requirements of Rule
4.5 adopted by the CFTC.  The Rule does not limit the  percentage  of the Fund's
assets that may be used for Futures  margin and related  options  premiums for a
bona fide  hedging  position.  However,  under the Rule the Fund must  limit its
aggregate  initial futures margin and related option premiums to no more than 5%
of the Fund's net assets for hedging  strategies  that are not  considered  bona
fide hedging  strategies  under the Rule. Under the Rule, the Fund also must use
short  Futures  and  Futures  options  positions  solely for "bona fide  hedging
purposes"  within the meaning  and intent of the  applicable  provisions  of the
Commodity Exchange Act.

    Transactions  in options by the Fund are subject to limitations  established
by option exchanges  governing the maximum number of options that may be written
or held by a single investor or group of investors acting in concert, regardless
of whether  the  options  were  written or  purchased  on the same or  different
exchanges or are held in one or more  accounts or through one or more  different
exchanges or through one or more  brokers.  Thus the number of options which the
Fund may  write or hold may be  affected  by  options  written  or held by other
entities,  including other  investment  companies having the same adviser as the
Fund (or an adviser that is an affiliate of the Fund's  adviser).  The exchanges
also impose position limits on Futures  transactions.  An exchange may order the
liquidation of positions found to be in violation of those limits and may impose
certain other sanctions.

     Due to  requirements  under  the  Investment  Company  Act,  when  the Fund
purchases an Interest Rate Future or Municipal Bond Index Future,  the Fund will
maintain,  in a  segregated  account or  accounts  with its  Custodian,  cash or
readily-marketable,  short-term  (maturing in one year or less) debt instruments
in an amount equal to the market value of the securities underlying such Future,
less the margin deposit applicable to it.

   
    o Tax Aspects of Covered Calls and Hedging Instruments.  The Fund intends to
qualify as a "regulated  investment  company"  under the  Internal  Revenue Code
(although it reserves the right not to qualify).  That qualification enables the
Fund to "pass  through" its income and realized  capital  gains to  shareholders
without having to pay tax on them. This avoids a "double tax" on that income and
capital gains,  since  shareholders  normally will be taxed on the dividends and
capital gains they receive from the Fund (unless the Fund's shares are held in a
retirement account or the shareholder is otherwise exempt from tax).
    

    o Risks of Hedging  With  Options and  Futures.  An option  position  may be
closed out only on a market that provides  secondary  trading for options of the
same series, and there is no assurance that a liquid secondary market will exist
for any particular option. In addition to the risks associated with hedging that
are  discussed  in the  Prospectus  and  above,  there is a risk in using  short
hedging by selling  Interest Rate Futures or Municipal Bond Index  Futures.  The
risk is that the prices of such Futures or the  applicable  index will correlate
imperfectly  with the behavior of the cash (i.e.,  market  value)  prices of the
Fund's  securities.  The ordinary spreads between prices in the cash and futures
markets are subject to  distortions,  due to differences in the natures of those
markets.  First,  all  participants in the futures markets are subject to margin
deposit and  maintenance  requirements.  Rather than meeting  additional  margin
deposit  requirements,   investors  may  close  out  futures  contracts  through
offsetting  transactions which could distort the normal relationship between the
cash and futures markets.  Second,  the liquidity of the futures markets depends
on  participants  entering into  offsetting  transactions  rather than making or
taking  delivery.  To the extent  participants  decide to make or take delivery,
liquidity in the futures  markets could be reduced,  thus producing  distortion.
Third,  from the point of view of speculators,  the deposit  requirements in the
futures  markets are less onerous  than margin  requirements  in the  securities
markets.  Therefore,  increased  participation  by  speculators  in the  futures
markets may cause temporary price distortions.

    The risk of imperfect correlation increases as the composition of the Fund's
portfolio  diverges from the  securities  included in the applicable  index.  To
compensate for the imperfect correlation of movements in the price of the equity
securities  being hedged and movements in the price of the hedging  instruments,
the Fund may use hedging  instruments in a greater dollar amount than the dollar
amount of equity  securities  being hedged if the  historical  volatility of the
prices  of the  debt  securities  being  hedged  is  more  than  the  historical
volatility  of the  applicable  index.  It is also possible that if the Fund has
used hedging  instruments in a short hedge, the market may advance and the value
of debt securities held in the Fund's  portfolio may decline.  If that occurred,
the Fund would lose  money on the  hedging  instruments  and also  experience  a
decline in value in its portfolio  securities.  However,  while this could occur
for a very  brief  period or to a very  small  degree,  over time the value of a
diversified portfolio of debt securities will tend to move in the same direction
as the indices upon which the hedging instruments are based.

     If the Fund uses  hedging  instruments  to establish a position in the debt
markets as a temporary substitute for the purchase of individual debt securities
(long hedging) by buying  Interest Rate Futures or Municipal Bond Futures and/or
calls on such Futures,  on securities or on stock  indices,  it is possible that
the  market  may  decline.  If the Fund  then  concludes  not to  invest in such
securities  at that time  because of  concerns as to a possible  further  market
decline  or for  other  reasons,  the Fund will  realize  a loss on the  hedging
instruments  that  is not  offset  by a  reduction  in  the  price  of the  debt
securities purchased.

   
    o  When-Issued  and  Delayed  Delivery   Transactions.   As  stated  in  the
Prospectus,  the Fund may invest in Municipal  Securities on a "when-issued"  or
"delayed  delivery" basis.  Payment for and delivery of the securities  normally
occurs within six months of the purchase of municipal bonds and notes.  However,
the Fund may, from time to time, purchase municipal  securities whose settlement
extends beyond six months and possibly as long as two years or more beyond trade
date.  The purchase  price and yield are fixed at the time the buyer enters into
the commitment. During the period between purchase and settlement, no payment is
made by the Fund to the  issuer  and no  interest  accrues to the Fund from this
investment.  However,  the Fund intends to be as fully  invested as possible and
will not invest in when- issued securities if its income or net asset value will
be materially  adversely affected.  At the time the Fund makes the commitment to
purchase  a  Municipal  Security  on a  when-issued  basis,  it will  record the
transaction  on its books and reflect the value of the  security in  determining
its net asset  value.  It will also  segregate  cash or other  liquid  Municipal
Securities  equal in value to the  commitment  for the  when-issued  securities.
While  when-issued  securities  may be sold prior to settlement  date,  the Fund
intends to acquire the securities  upon  settlement  unless a prior sale appears
desirable for investment  reasons.  There is a risk that the yield  available in
the market when  delivery  occurs may be higher  than the yield on the  security
acquired.
    

     o  Repurchase  Agreements.  The  Fund may  acquire  securities  subject  to
repurchase agreements for liquidity purposes to meet anticipated redemptions, or
pending the investment of the proceeds from sales of Fund shares, or pending the
settlement of purchases of portfolio securities.

    In a  repurchase  transaction,  the  Fund  acquires  a  security  from,  and
simultaneously resells it to, an approved vendor. An "approved vendor" is a U.S.
commercial bank or the U.S.  branch of a foreign bank or a  broker-dealer  which
has been designated a primary dealer in government  securities,  which must meet
credit  requirements set by the Trust's Board of Trustees from time to time. The
resale  price  exceeds  the  purchase  price  by  an  amount  that  reflects  an
agreed-upon  interest rate  effective for the period during which the repurchase
agreement is in effect.  The majority of these transactions run from day to day,
and delivery pursuant to the resale typically will occur within one to five days
of  the  purchase.  Repurchase  agreements  are  considered  "loans"  under  the
Investment Company Act,  collateralized by the underlying  security.  The Fund's
repurchase  agreements require that at all times while the repurchase  agreement
is in effect,  the value of the  collateral  must equal or exceed the repurchase
price to fully collateralize the repayment obligation. Additionally, the Manager
will  impose  creditworthiness  requirements  to  confirm  that  the  vendor  is
financially sound and will continuously monitor the collateral's value.

    o Loans of Portfolio Securities.  The Fund may lend its portfolio securities
subject  to  the  restrictions  stated  in  the  Prospectus.   Under  applicable
regulatory  requirements  (which are subject to change),  the loan collateral on
each  business  day must at least equal the value of the loaned  securities  and
must  consist  of  cash,  bank  letters  of  credit  or  securities  of the U.S.
Government  (or  its  agencies  or  instrumentalities).   To  be  acceptable  as
collateral,  letters of credit must  obligate a bank to pay amounts  demanded by
the Fund if the demand meets the terms of the letter. Such terms and the issuing
bank  must be  satisfactory  to the  Fund.  When it lends  securities,  the Fund
receives  amounts  equal to the dividends or interest on loaned  securities  and
also  receives  one or  more  of (a)  negotiated  loan  fees,  (b)  interest  on
securities  used as collateral,  and (c) interest on short-term  debt securities
purchased with such loan collateral.  Either type of interest may be shared with
the borrower. The Fund may also pay reasonable finder's, administrative or other
fees.  The terms of the  Fund's  loans  must  meet  applicable  tests  under the
Internal Revenue Code and must permit the Fund to reacquire loaned securities on
five days' notice or in time to vote on any important matter.

Other Investment Restrictions

    The Fund's most  significant  investment  restrictions  are set forth in the
Prospectus.  There are  additional  investment  restrictions  that the Fund must
follow that are also fundamental  policies.  Fundamental policies and the Fund's
investment  objective  cannot be changed without the vote of a "majority" of the
Fund's outstanding  voting securities.  Under the Investment Company Act, such a
"majority"  vote of the Fund is defined as the vote of the holders of the lesser
of:  (i) 67% or more of the  shares  present  or  represented  by  proxy at such
meeting,  if the holders of more than 50% of the outstanding shares are present,
or (ii) more than 50% of the outstanding shares.

    Under these additional restrictions, the Fund cannot:

    (1)  invest  in real  estate,  but this  shall  not  prevent  the Fund  from
    investing  in  Municipal  instruments  or other  permissible  securities  or
    instruments secured by real estate or interests thereon;

    (2)  invest in  interests  in oil,  gas,  or other  mineral  exploration  or
    development programs;

    (3) purchase securities, or other instruments,  on margin; however, the Fund
    may invest in options,  futures,  options on futures and similar instruments
    and may make margin deposits and payments in connection therewith;

    (4) make short sales of securities;

    (5) underwrite  securities except to the extent the Fund may be deemed to be
    an  underwriter  in  connection  with  the  sale of  securities  held in its
    portfolio;

    (6) invest in securities of other investment  companies,  except as they may
    be acquired as part of a merger, consolidation or other acquisition;

    (7) make investments for the purpose of exercising control of management; or

    (8) purchase  securities of any issuer if, to the knowledge of the Fund, its
    officers  and  trustees  and  officers  and  directors  of the  Manager  who
    individually  own more than 5% of the securities of such issuer together own
    beneficially more than 5% of such issuer's outstanding securities.

    As a matter of non-fundamental policy, the Fund shall not purchase or retain
securities  if as a result the Fund would have more than 5% of its total  assets
invested in  securities  of private  issuers  having a record of less than three
years'   continuous   operation  (such  period  may  include  the  operation  of
predecessor companies or enterprises) or in industrial  development bonds if the
private entity on whose credit the security is based, directly or indirectly, is
less than three years old (including predecessors), unless the security is rated
by a  nationally-recognized  rating  service;  or invest in common  stock or any
warrants related thereto.

       
    For  purposes  of the  Fund's  policy  not to  concentrate  described  under
investment  restriction  number 4 in the  Prospectus,  the Fund has  adopted the
industry classifications set forth in Appendix C to this Statement of Additional
Information. This is not a fundamental policy.

How the Fund Is Managed

Organization and History. Oppenheimer Municipal Fund is a Massachusetts business
trust and is composed of two series. The Fund is one of the series. The Trust is
not  required to hold,  and does not plan to hold,  regular  annual  meetings of
shareholders. The Trust and/or Fund will hold meetings when required to do so by
the  Investment  Company  Act or other  applicable  law,  or when a  shareholder
meeting is called by the  Trustees or upon proper  request of the  shareholders.
Shareholders  have  the  right,  upon  the  declaration  in  writing  or vote of
two-thirds  of the  outstanding  shares of the Trust,  to remove a Trustee.  The
Trustees will call a meeting of shareholders to vote on the removal of a Trustee
upon the written request of the record holders of 10% of the outstanding  shares
of the Trust.  In addition,  if the Trustees  receive a request from at least 10
shareholders (who have been shareholders for at least six months) holding shares
of the Trust  valued at $25,000  or more or  holding at least 1% of the  Trust's
outstanding  shares,  whichever is less,  stating that they wish to  communicate
with other  shareholders to request a meeting to remove a Trustee,  the Trustees
will then either make the Trust's  shareholder  list available to the applicants
or  mail  their  communication  to all  other  shareholders  at the  applicants'
expense,  or the Trustees may take such other action as set forth under  Section
16(c) of the Investment Company Act.

    Each share of the Fund  represents  an interest in the Fund  proportionately
equal to the  interest  of each other  share of the same class and  entitle  the
holder to one vote per share (and a fractional  vote for a fractional  share) on
matters submitted to their vote at shareholders'  meetings.  Shareholders of the
Trust  vote  together  in the  aggregate  on certain  matters  at  shareholders'
meetings,  such as the election of Trustees and  ratification  of appointment of
auditors  for the  Trust.  Shareholders  of a  particular  series or class  vote
separately on proposals which affect that series or class, and shareholders of a
series or class which is not affected by that matter are not entitled to vote on
the  proposal.  Shareholders  of a  class  vote  on  certain  amendments  to the
Distribution and/or Service Plans if the amendments affect that class.

    The Trustees are authorized to create new series and classes of series.  The
Trustees may  reclassify  unissued  shares of the Trust or its series or classes
into  additional  series or classes of shares.  The  Trustees may also divide or
combine the shares of a class into a greater or lesser number of shares provided
that the  proportionate  beneficial  interest of a  shareholder  in the Fund and
Trust is not changed.  Shares do not have cumulative voting rights or preemptive
or subscription rights. Shares may be voted in person or by proxy.

    The  Declaration of Trust  contains an express  disclaimer of shareholder or
Trustee liability for the Fund's  obligations,  and provides for indemnification
and  reimbursement  of expenses  out of its property  for any  shareholder  held
personally  liable for its  obligations.  The Declaration of Trust also provides
that the Fund shall, upon request,  assume the defense of any claim made against
any  shareholder  for any act or obligation of the Fund and satisfy any judgment
thereon. Thus, while Massachusetts law permits a shareholder of a business trust
(such as the Fund) to be held  personally  liable as a "partner"  under  certain
circumstances,  the  risk  of a Fund  shareholder  incurring  financial  loss on
account  of  shareholder   liability  is  limited  to  the   relatively   remote
circumstances  in  which  the  Fund  would be  unable  to meet  its  obligations
described  above.  Any person doing business with the Trust, and any shareholder
of the Trust,  agrees under the Trust's  Declaration  of Trust to look solely to
the assets of the Trust for  satisfaction of any claim or demand which may arise
out of any  dealings  with the Trust,  and the  Trustees  shall have no personal
liability to any such person, to the extent permitted by law.

1  For the 1997 calendar year.

2 Committee  positions  effective July 1, 1997. 3 Prior to July 1, 1997, Messrs.
Conrad and Kirchner were also members of the Audit and Review Committee.

      o Deferred Compensation Plan. The Board of Trustees has adopted a Deferred
Compensation Plan for  disinterested  Trustees that enables Trustees to elect to
defer  receipt  of all or a portion  of the  annual  fees they are  entitled  to
receive from the Fund. Under the plan, the compensation deferred by a Trustee is
periodically 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 Fund's assets, liabilities or net income per share. The plan will not
obligate the Fund to retain the services of any Trustee or to pay any particular
amount  of  compensation  to any  Trustee.  Pursuant  to an Order  issued by the
Securities and Exchange  Commission,  the Fund may, without shareholder approval
and  notwithstanding  its  fundamental  policy  restricting  investment in other
open-end  investment  companies,  as described  above on page 12,  invest in the
funds  selected  by a  Trustee  under  the  plan  for  the  limited  purpose  of
determining the value of the Trustee's deferred fee account.

      o Major  Shareholders.  As of December 31, 1997,  (i) Merrill Lynch Pierce
Fenner & Smith, 4800 Deer Lake Drive EFL3,  Jacksonville,  Florida, 32246, owned
49,500.000 Class B shares  (representing 7.94% of the Fund's outstanding Class B
shares and (ii) Merrill Lynch Pierce Fenner & Smith,  4800 Deer Lake Drive EFL3,
Jacksonville,  Florida,  32246,  owned 100,188.000 Class C shares  (representing
10.19% of the Fund's  outstanding  Class C  shares).  No other  person  owned of
record or was known by the Trust to own beneficially 5% or more of the shares of
the Trust as a whole or either class of the Fund's outstanding shares as of that
date.

     The Manager and Its Affiliates.  The Manager is wholly-owned by Oppenheimer
Acquisition Corp. ("OAC"), a holding company controlled by Massachusetts  Mutual
Life  Insurance  Company.  OAC is also owned in part by certain of the Manager's
directors and officers, some of whom may also serve as officers of the Fund, and
three of whom (Ms. Macaskill,  Mr. Swain and Mr. Bowen) serve as Trustees of the
Fund.
    

      The Manager  and the Fund have a Code of Ethics.  It is designed to detect
and prevent improper personal trading by certain employees,  including portfolio
managers,  that would  compete with or take  advantage  of the Fund's  portfolio
transactions.  Compliance  with the Code of Ethics is  carefully  monitored  and
strictly enforced by the Manager.

   
      |X|  Portfolio  Management.  The  portfolio  manager  of the Fund is Caryn
Halbrecht,  who is principally  responsible for the day-to-day management of the
Fund's portfolio. The background of Ms. Halbrecht is described in the Prospectus
under "Portfolio Manager." Other members of the Manager's fixed-income portfolio
department,   particularly  portfolio  analysts,  traders  and  other  portfolio
managers having broad experience with domestic and international  government and
corporate  fixed-income  securities,  provide the Fund's portfolio managers with
support in managing the Fund's portfolio.

      o The Investment  Advisory  Agreement.  The Investment  Advisory Agreement
between the Manager and the Trust on behalf of the Fund requires the Manager, at
its expense,  to provide the Fund with  adequate  office space,  facilities  and
equipment, and to provide and supervise the activities of all administrative and
clerical  personnel required to provide effective  corporate  administration for
the Fund,  including the  compilation and maintenance of records with respect to
its  operations,  the  preparation  and  filing of  specified  reports,  and the
composition of proxy materials and registration statements for continuous public
sale of shares of the Fund.

      Expenses  not  expressly  assumed  by the  Manager  under  the  Investment
Advisory  Agreement  or by  the  Distributor  under  the  General  Distributor's
Agreement are paid by the Fund. Expenses with respect to the Trust's two series,
including  the  Fund,  are  allocated  in  proportion  to the net  assets of the
respective  Funds,  except where  allocations of direct  expenses could be made.
Certain expenses are further  allocated to certain classes of shares of a series
as  explained  in the  Prospectus  and  under  "How to Buy  Shares"  below.  The
Investment  Advisory  Agreement lists examples of expenses paid by the Fund, the
major categories of which relate to interest, taxes, brokerage commissions, fees
to certain  Trustees,  legal and audit  expenses,  custodian and transfer  agent
expenses,  share issuance costs,  certain  printing and  registration  costs and
non-recurring  expenses,  including  litigation costs.  During the Fund's fiscal
years ended  September 30, 1995 , 1996 and 1997, the management fees paid by the
Fund to the Manager were $435,665 , $463,582 and $509,834, respectively.

      The Investment Advisory Agreement contains no expense limitation. However,
because of state regulations limiting fund expenses that previously applied, the
Manager had voluntarily  undertaken that the Fund's total expenses in any fiscal
year  (including the investment  advisory fee but exclusive of taxes,  interest,
brokerage   commissions,   distribution  plan  payments  and  any  extraordinary
non-recurring  expenses,   including  litigation)  would  not  exceed  the  most
stringent state regulatory  limitation applicable to the Fund. Due to changes in
federal  securities  laws,  such  state  regulations  no  longer  apply  and the
Manager's undertaking is therefore  inapplicable and has been withdrawn.  During
the  Fund's  last  fiscal  year,  the  Fund's  expenses  did not exceed the most
stringent state regulatory limit and the voluntary undertaking was not invoked.
    

      The  advisory   agreement   provides   that  in  the  absence  of  willful
misfeasance,  bad faith or gross negligence in the performance of its duties, or
reckless disregard for its obligations and duties under the advisory  agreement,
the  Manager  is not liable for any loss  resulting  from a good faith  error or
omission on its part with respect to any of its duties thereunder.  The advisory
agreement permits the Manager to act as investment adviser for any other person,
firm or corporation and to use the name  "Oppenheimer"  in connection with other
investment  companies,  for which it may act as  investment  adviser  or general
distributor.  If the Manager  shall no longer act as  investment  adviser to the
Fund,  the right of the Fund to use the name  "Oppenheimer"  as part of its name
may be withdrawn.

     o The Distributor. Under its General Distributor's Agreement with the Fund,
the  Distributor,   OppenheimerFunds  Distributor,  Inc.,  acts  as  the  Fund's
principal  underwriter in the continuous  public offering of the Fund's Class A,
Class B and Class C shares,  but is not  obligated to sell a specific  number of
shares.  Expenses normally  attributable to sales,  excluding payments under the
Distribution  and  Service  Plans,  but  including  advertising  and the cost of
printing  and  mailing  prospectuses  (other  than those  furnished  to existing
shareholders) are borne by the Distributor.

   
      During the Fund's  fiscal years ended  September 30, 1995 , 1996 and 1997,
the aggregate  sales charges on sales of the Fund's Class A shares were $160,045
,  $160,206  and  $173,050,  respectively,  of  which  the  Distributor  and  an
affiliated broker-dealer retained in the aggregate $62,159 , $85,052 and $75,561
in these  respective  years.  During the Fund's fiscal year ended  September 30,
1997,  the  contingent  deferred  sales charges  collected on the Fund's Class B
shares totalled $13,462 and the contingent  deferred sales charges  collected on
Class C shares  totalled  $8,862,  all of which the  Distributor  retained.  For
additional  information about distribution of the Fund's shares and the expenses
connected  with such  activities,  please  refer to  "Distribution  and  Service
Plans," below.

     o The Transfer Agent. The Fund's Transfer Agent, OppenheimerFunds Services,
a division of the Manager, is responsible for maintaining the Fund's shareholder
registry and shareholder accounting records, and for shareholder servicing and
administrative functions.
    

Brokerage Policies of the Fund

Brokerage Provisions of the Investment Advisory Agreement.  One of the duties of
the Manager under the Investment  Advisory Agreement is to arrange the portfolio
transactions for the Fund. The Investment Advisory Agreement contains provisions
relating to the  employment of  broker-dealers  ("brokers") to effect the Fund's
portfolio transactions. In doing so, the Manager is authorized by the Investment
Advisory  Agreement  to  employ  such  broker-dealers,   including  "affiliated"
brokers,  as that term is defined in the Investment  Company Act, as may, in its
best judgment based on all relevant factors, implement the policy of the Fund to
obtain,  at  reasonable  expense,  the "best  execution"  (prompt  and  reliable
execution at the most  favorable  price  obtainable) of such  transactions.  The
Manager need not seek competitive commission bidding but is expected to minimize
the commissions paid to the extent  consistent with the interest and policies of
the Fund as established by its Board of Trustees.

      Under the advisory agreement,  the Manager is authorized to select brokers
other than affiliates that provide  brokerage  and/or research  services for the
Fund and/or the other  accounts  over which the Manager or its  affiliates  have
investment  discretion.  The commissions paid to such brokers may be higher than
another  qualified  broker would have charged if a good faith  determination  is
made by the Manager that the  commission  is fair and  reasonable in relation to
the services provided. Subject to the foregoing considerations,  the Manager may
also consider sales of shares of the Fund and other investment companies managed
by the Manager or its affiliates as a factor in the selection of brokers for the
Fund's portfolio transactions.

   
Description  of  Brokerage  Practices  Followed by the  Manager.  Subject to the
provisions of the  Investment  Advisory  Agreement and the  procedures and rules
described  above,  allocations  of brokerage are generally made by the Manager's
portfolio traders upon recommendations from the Manager's portfolio managers. In
certain  instances,  portfolio  managers may directly  place trades and allocate
brokerage,  also subject to the provisions of the Investment  Advisory Agreement
and the  procedures  and rules  described  above.  In either case,  brokerage is
allocated under the  supervision of the Manager's  executive  officers.  As most
purchases made by the Fund are principal  transactions  at net prices,  the Fund
does not incur substantial brokerage costs. The Fund usually deals directly with
the selling or purchasing  principal or market maker without  incurring  charges
for the services of a broker on its behalf unless it is determined that a better
price or  execution  may be  obtained  by  utilizing  the  services of a broker.
Purchases of portfolio  securities  from  underwriters  include a commission  or
concession  paid by the issuer to the  underwriter  and  purchases  from dealers
include a spread  between  the bid and  asked  price.  The Fund  seeks to obtain
prompt  execution  of orders at the most  favorable  net  prices.  When the Fund
engages in an option  transaction,  ordinarily  the same broker will be used for
the  purchase or sale of the option and any  transaction  in the  securities  to
which the option relates.  When possible,  concurrent orders to purchase or sell
the same security by more than one of the accounts managed by the Manager or its
affiliates are combined.  The  transactions  effected  pursuant to such combined
orders are averaged as to price and allocated in accordance with the purchase or
sale orders actually placed for each account.
    

      Other funds advised by the Manager have investment objectives and policies
similar to those of the Fund.  Such other  funds may  purchase  or sell the same
securities at the same time as the Fund, which could affect the supply and price
of such  securities.  If two or more of such funds purchase the same security on
the same day from the same  dealer,  the  Manager  may  average the price of the
transactions and allocate the average among such funds.

      The research  services  provided by a particular broker may be useful only
to one or more of the advisory  accounts of the Manager and its affiliates,  and
investment  research received for the commissions of those other accounts may be
useful both to the Fund and one or more of such other  accounts.  Such research,
which may be  supplied by a third  party at the  instance of a broker,  includes
information  and analyses on  particular  companies  and  industries  as well as
market or economic trends and portfolio  strategy,  receipt of market quotations
for portfolio  evaluations,  information systems,  computer hardware and similar
products  and  services.  If a research  service  also  assists the Manager in a
non-research  capacity (such as bookkeeping or other administrative  functions),
then only the percentage or component that provides assistance to the Manager in
the investment  decision-making  process may be paid in commission dollars.  The
Board  of  Trustees  permits  the  Manager  to use  concessions  on  fixed-price
offerings  to obtain  research,  in the same manner as is  permitted  for agency
transactions.  The Board also permits the Manager to use stated  commissions  on
secondary  fixed-income  agency trades to obtain  research  where the broker has
represented  to the Manager that:  (i) the trade is not from or for the broker's
own  inventory,  (ii) the trade was executed by the broker on an agency basis at
the  stated  commission,  and  (iii)  the  trade  is  not a  riskless  principal
transaction.

      The  research   services  provided  by  brokers  broadens  the  scope  and
supplement  the  research   activities  of  the  Manager,  by  making  available
additional views for consideration and comparisons,  and by enabling the Manager
to obtain market  information for the valuation of securities held in the Fund's
portfolio or being considered for purchase.  The Manager provides information as
to the commissions  paid to brokers  furnishing such services  together with the
Manager's  representation  that the amount of such  commissions  was  reasonably
related to the value or benefit of such services.

Performance of the Fund

Yield and Total Return Information. As described in the Prospectus, from time to
time  the  "standardized  yield,"   "tax-equivalent  yield,"  "dividend  yield,"
"average annual total return,"  "cumulative total return," "average annual total
return  at net  asset  value"  and  "total  return  at net  asset  value"  of an
investment in a class of Fund shares may be  advertised.  An  explanation of how
yields and total returns
 are calculated for each class and the components of those  calculations  is set
forth below.  Class B shares were first publicly  offered on September 11, 1995.
Class C shares were first publicly offered on December 1, 1993.

rules of the  Securities  and Exchange  Commission,  include the average  annual
total returns for each  advertised  class of shares of the Fund for the 1, 5 and
10-year  periods  (or the  life of the  class,  if less)  ending  as of the most
recently-ended  calendar quarter prior to the publication of the  advertisement.
This enables an investor to compare the Fund's performance to the performance of
other  funds  for the same  periods.  However,  a number  of  factors  should be
considered  before using such  information as a basis for comparison  with other
investments.  An  investment  in the Fund is not  insured;  its  yield and total
returns are not guaranteed  and normally will  fluctuate on a daily basis.  When
redeemed,  an  investor's  shares may be worth more or less than their  original
cost.  Yield and total returns for any given past period are not a prediction or
representation  by the Fund of future  yields or rates of return.  The yield and
total  returns of each  class of shares of the Fund are  affected  by  portfolio
quality,  portfolio  maturity,  the type of  investments  the Fund holds and its
operating expenses allocated to the particular class.
    

   
      o  Yield

      o  Standardized  

Yield. The "standardized yield" (referred to as "yield") is shown for a class of
shares for a stated 30-day period. It is not based on actual  distributions paid
by the Fund to  shareholders in the 30-day period,  but is a hypothetical  yield
based upon the net investment  income from the Fund's portfolio  investments for
that period.  It may  therefore  differ from the  "dividend  yield" for the same
class of shares,  described below. It is calculated using the following  formula
set forth in rules adopted by the Securities and Exchange  Commission , designed
to assure uniformity in the way that all funds calculate their yields:
    

Standardized ~Yield ~ = ~ 2~ [~ (~ {a-b} over cd ~ +~ 1~ ) SUP 6~ -~ 1~ ]

      The symbols above represent the following factors:

      a  =dividends and interest earned during the 30-day period.
      b  =expenses  accrued  for the  period  (net  of any  expense
          reimbursements).
      c   =the average daily number of shares of that class  outstanding  during
          the 30-day period that were entitled to receive dividends.
      d   =the maximum offering price per share of that class on the last day of
          the period, adjusted for undistributed net investment income.

   
     The  standardized  yield for a 30-day  period may differ from the yield for
other periods.  The SEC formula assumes that the standardized yield for a 30-day
period occurs at a constant rate for a six-month period and is annualized at the
end of the  six-month  period.  Additionally,  because  each  class of shares is
subject to different expenses,  it is likely that the standardized yields of the
Fund's  classes of shares  will  differ for any  30-day  period.  For the 30-day
period ended September 30, 1997, the standardized  yields for the Fund's classes
of shares were as follows:

Without Deducting Sales Charge          With Sales Charge Deducted

Class A:  4.16%                           4.32%
Class B:  3.56%                           N/A
Class C:  3.56%                           N/A

      o Tax-Equivalent  Yield. The  "tax-equivalent  yield" of a class of shares
adjusts the Fund's  current yield,  as calculated  above,  by a stated  combined
Federal  and  state  tax  rate.  The tax  equivalent  yield is based on a 30-day
period, and is computed by dividing the tax-exempt portion of the Fund's current
yield (as calculated above) by one minus a stated income tax rate and adding the
result  to the  portion  (if  any)  of the  Fund's  current  yield  that  is not
tax-exempt.  The tax-equivalent  yield may be used to compare the tax effects of
income  derived  from the Fund with income from taxable  investments  at the tax
rates stated. Appendix B includes a tax equivalent yield table, based on various
effective  tax  brackets  for  individual  taxpayers.   Such  tax  brackets  are
determined  by a  taxpayer's  Federal and state  taxable  income (the net amount
subject to Federal and state income tax after  deductions and  exemptions).  The
tax-equivalent  yield  tables  assumes that the investor is taxed at the highest
bracket, regardless of whether a switch to non-taxable investments would cause a
lower  bracket to apply and that state income tax payments are fully  deductible
for income tax  purposes.  For  taxpayers  with  income  above  certain  levels,
otherwise allowable itemized deductions are limited.  The Fund's  tax-equivalent
yield for its Class A, Class B and Class C shares for the  30-day  period  ended
September 30, 1997 were 6.89%, 5.89% and 5.89%, respectively,  for an individual
in the 39.6% Federal tax bracket.

      o Dividend Yield . The Fund may quote a "dividend yield" for each class of
its shares.  Dividend  yield is based on the dividends paid on shares of a class
during the actual dividend period. To calculate dividend yield, the dividends of
a class  declared  during a stated  period  are  added  together  and the sum is
multiplied by 12 (to  annualize  the yield) and divided by the maximum  offering
price on the last day of the dividend period. The formula is shown below:

      Dividend Yield = dividends  paid  x  12/maximum offering price 
                                                (payment date)

      The maximum offering price for Class A shares includes the maximum initial
sales charge.  The maximum  offering price for Class B and Class C shares is the
net asset value per share, without considering the effect of contingent deferred
sales charges.  The Class A dividend yield may also be quoted without  deducting
the maximum initial sales charge .

      The dividend yields for the 30-day period ended September 30, 1997 were as
follows:

Without Deducting Sales Charge          With Sales Charge Deducted

Class A:  5.00%                           5.18%
Class B:  4.42%                           N/A
Class C:  4.42%                           N/A
    

      o Total Return Information.

      o Average Annual Total Returns.  The "average annual total return" of each
class  is an  average  annual  compounded  rate of  return  for  each  year in a
specified number of years. It is the rate of return based on the change in value
of a hypothetical  initial  investment of $1,000 ("P" in the formula below) held
for a number of years  ("n") to achieve an Ending  Redeemable  Value  ("ERV") of
that investment, according to the following formula:

               LEFT ( {~ERV~} OVER P~ right) SUP
            {1/n}~-1~=~Average~Annual~Total~ Return

   
      The "average  annual total  return" on an  investment in Class A shares of
the Fund for the one , five and ten year periods  ended  September 30, 1997 were
4.91%,  5.42% and 8.15%,  respectively.  The "average annual total return" on an
investment  in Class B shares for the year ended  September  30, 1997 was 3.89%.
The "average  annual total  return" on an  investment  in Class B shares for the
period from  inception on  September  11, 1995  through  September  30, 1997 was
5.19%.  The "average annual total return" on an investment in Class C shares for
the year ended  September 30, 1997 was 6.85%,  and for the period from inception
on December 1, 1993 through September 30, 1997 was 4.63%.
    

      o Cumulative  Total Return.  The  "cumulative  total  return"  calculation
measures the change in the value of a hypothetical  investment of $1,000 over an
entire period of years. Its calculation uses some of the same factors as average
annual  total  return,  but it does not  average the rate of return on an annual
basis. Cumulative total return is determined as follows:

                  {ERV~-~P} over P ~ =~Total~Return

   
      In calculating total returns for Class A shares, the current maximum sales
charge of 3.50% (as a  percentage  of the offering  price) is deducted  from the
initial  investment  ("P")  (unless the return is shown at net asset  value,  as
discussed  below).  For Class B shares,  payment of  contingent  deferred  sales
charge of 5.0% for the first year,  4.0% for the second year, 3.0% for the third
and  fourth  years,  2.0% in the fifth  year,  1.0% in the  sixth  year and none
thereafter is applied,  as described in the Prospectus.  For Class C shares, the
payment of the 1.0% contingent  deferred sales charge for the first 12 months is
applied,  as described  in the  Prospectus.  Total  returns also assume that all
dividends and capital gains  distributions  during the period are  reinvested to
buy additional  shares at net asset value per share,  and that the investment is
redeemed  at  the  end of the  period.  The  ""cumulative  total  return"  on an
investment in Class A shares of the Fund (using the method  described above) for
the one year , five year and ten year  periods  ended  September  30,  1997 were
4.91%, 30.19% and 118.83%. The cumulative total return on Class B shares for the
one year period ended September 30, 1997 was 3.88%.  The cumulative total return
on Class B shares for the period September 11, 1995 (the inception of the Class)
through  September 30, 1997 was 10.95%.  The cumulative  total return on Class C
shares for the one year period  ended  September  30, 1997 was 6.85% and for the
period from December 1, 1993 (the inception of the class) through  September 30,
1997 was 18.94%.  During a portion of the  periods  for which total  returns are
shown, the Fund's maximum sales charge rate was higher; as a result, performance
returns on actual investments during those periods may be lower than the results
shown.

      o Total  Returns at Net Asset  Value.  From time to time the Fund may also
quote an average  annual total  return at net asset value or a cumulative  total
return at net asset value for Class A, Class B or Class C shares.  Each is based
on the  difference  in net asset value per share at the beginning and the end of
the  period  for a  hypothetical  investment  in that  class of shares  (without
considering  front-end  or  contingent  deferred  sales  charges) and takes into
consideration the reinvestment of dividends and capital gains distributions. The
"average  annual  total  return at net asset value" on the Fund's Class A shares
for the one-year , five-year and ten-year  periods ended  September 30, 1997 was
8.72%, 6.17% and 8.53%,  respectively.  The cumulative total return at net asset
value for Class A shares for the ten-year  period ended  September  30, 1997 was
126.78%.  The  "average  annual  total  return at net asset value" on the Fund's
Class B  shares  from  September  11,  1995  (inception  of the  Class)  through
September 30, 1997 was 6.11%.  The cumulative  "total returns at net asst value"
on the Fund's Class B shares for the period September 11, 1995 (inception of the
Class) through September 30, 1997 was 12.95%. The average annual total return at
net asset value for the Fund's Class C shares year ended  September 30, 1997 was
7.85%.
    

      Total return  information  may be useful to  investors  in  reviewing  the
performance  of the  Fund's  Class A, Class B or Class C shares.  However,  when
comparing total return of an investment in Class A, Class B or Class C shares of
the Fund, a number of factors should be considered before using such information
as a basis for comparison before using such information with other investments.

   
      o Other  Performance  Comparisons.  From time to time the Fund may publish
the  ranking  of the  performance  of its Class A,  Class B or Class C shares by
Lipper Analytical  Services,  Inc. ("Lipper"),  a widely-recognized  independent
mutual fund  monitoring  service.  Lipper  monitors the performance of regulated
investment  companies,  including  the Fund,  and ranks  their  performance  for
various  periods based on  categories  relating to  investment  objectives.  The
performance of the Fund is ranked  against (i) all other bond funds,  other than
money market funds,  and (ii) all other  intermediate  municipal debt funds. The
Lipper  performance  rankings  are  based  on total  returns  that  include  the
reinvestment of capital gain  distributions and income dividends but do not take
sales  charges  or  taxes  into  consideration.  From  time to time the Fund may
include in its advertisement and sales literature performance  information about
the Fund cited in other  newspapers and periodicals  such as The New York Times,
which may include  performance  quotations from other sources,  including Lipper
and  Morningstar.  The  performance  of the  Fund's  Class A, Class B or Class C
shares may be compared in  publications to (i) the performance of various market
indices  or  to  other  investments  for  which  reliable  performance  data  is
available,  and (ii) to  averages,  performance  rankings  or  other  benchmarks
prepared by recognized mutual fund statistical services.

      From time to time the Fund may publish the star ranking of the performance
of its Class A, Class B or Class C shares by  Morningstar,  Inc., an independent
mutual fund monitoring service . Morningstar ranks mutual funds monthly in broad
investment categories:  domestic stock funds, international stock funds, taxable
bond funds and municipal bond funds,  based on  risk-adjusted  total  investment
return.  The Fund is ranked among the municipal  bond funds.  Investment  return
measures a fund's or class's one, three,  five and ten-year average annual total
returns available)(depending on the inception of the fund or class) in excess of
90-day U.S. Treasury bill returns after considering the fund's sales charges and
expenses.  Risk  measures  a fund's or class's  performance  below  90-day  U.S.
Treasury bill returns.  Risk and investment  return are combined to produce star
rankings  reflecting  performance  relative  to the  average  fund  in a  fund's
category.  Five stars is the "highest"  ranking (top 10%),  four stars is "above
average" (next 22.5%),  three stars is "average" (next 35%), two stars is "below
average"  (next 22.5%) and one star is "lowest"  (bottom 10%).  The current star
ranking is the fund's or class's  3-year  ranking or its  combined 3- and 5-year
ranking  (weighted  60%/40%  respectively,  or its  combined  3-. 5- and 10-year
ranking (weighted 40%, 30% and 30%, respectively), depending on the inception of
the fund or class. Rankings are subject to change monthly.

      The Fund may also  compare its  performance  to that of other funds in its
Morningstar  Category.  In  addition  to its  star  rankings,  Morningstar  also
categorizes  and compares a fund's  3-year  performance  based on  Morningstar's
classification of the fund's investments and investment style, rather than how a
fund  defines its  investment  objective.  Morningstar's  four broad  categories
(domestic  equity,  international  equity,  municipal bond and taxable bond) are
each  further  subdivided  into  categories  based on types of  investments  and
investment  styles.  Those comparisons by Morningstar are based on the same risk
and return  measurements  as its star rankings but do not consider the effect of
sales charges.
    

      Investors  may also wish to compare the Fund's Class A, Class B or Class C
return to the  returns  on fixed  income  investments  available  from banks and
thrift institutions,  such as certificates of deposit,  ordinary interest-paying
checking  and  savings  accounts,  and  other  forms of fixed or  variable  time
deposits,  and various other  instruments such as Treasury bills.  However,  the
Fund's  returns and share price are not guaranteed or insured by the FDIC or any
other agency and will fluctuate daily, while bank depository  obligations may be
insured by the FDIC and may provide  fixed rates of return,  and Treasury  bills
are guaranteed as to principal and interest by the U.S. government.

   
      From time to time, the Fund's  Manager may publish  rankings or ratings of
the Manager (or Transfer Agent), or on the investor services provided by them to
shareholders of the Oppenheimer  funds,  other than the performance  rankings of
the   Oppenheimer   funds    themselves.    Those   ratings   or   rankings   of
shareholder/investor services by a third party may compare the Oppenheimer funds
services  to those of other  mutual  fund  families  selected  by the  rating or
ranking  services,  and may be based upon the  opinions of the rating or ranking
service  itself,  based on its  research or  judgment,  or based upon surveys of
investors, brokers, shareholders or others. Distribution and Service Plans
    

      The Fund has  adopted a Service  Plan for Class A shares and  Distribution
and Service Plans for Class B and Class C shares of the Fund under Rule 12b-1 of
the  Investment  Company Act,  pursuant to which the Fund makes  payments to the
Distributor in connection with the  distribution  and/or servicing of the shares
of that class, as described in the Prospectus.  Each Plan has been approved by a
vote of (i) the Board of  Trustees  of the Fund,  including  a  majority  of the
Independent  Trustees,  cast in person at a meeting  called  for the  purpose of
voting on that Plan,  and (ii) the  holders of a  "majority"  (as defined in the
Investment  Company Act) of the shares of each class.  For the  Distribution and
Service  Plan for Class C shares,  that vote was cast by the Manager as the sole
initial holder of Class C shares.

      In  addition,  under the Plans the Manager and the  Distributor,  in their
sole discretion,  from time to time, may use their own resources  (which, in the
case of the Manager,  may include profits from the advisory fee it receives from
the Fund) at no cost to the Fund to make payments to brokers,  dealers, or other
financial  institutions  (each is referred to as a "Recipient"  under the Plans)
for distribution and administrative  services they perform.  The Distributor and
the Manager  may, in their sole  discretion,  increase or decrease the amount of
payments they make from their own resources to Recipients.

      Unless  terminated as described below,  each Plan continues in effect from
year to year but only as long as its  continuance  is  specifically  approved at
least annually by the Board of Trustees and its  Independent  Trustees by a vote
cast  in  person  at a  meeting  called  for  the  purpose  of  voting  on  such
continuance.  Each Plan may be  terminated at any time by the vote of a majority
of the  Independent  Trustees or by the vote of the holders of a "majority"  (as
defined in the Investment  Company Act) of the outstanding shares of that class.
No Plan may be amended to increase  materially the amount of payments to be made
unless such amendment is approved by  shareholders  of the class affected by the
amendment. In addition, because Class B shares of the Fund automatically convert
into Class A shares after six years,  the Fund is required by a  Securities  and
Exchange  Commission  rule to obtain the  approval of Class B as well as Class A
shareholders for a proposed  amendment to the Class A Plan that would materially
increase the amount to be paid by Class A  shareholders  under the Class A Plan.
Such  approval  must be by a  "majority"  of the Class A and Class B shares  (as
defined in the Investment Company Act), voting separately by Class. All material
amendments must be approved by the Independent Trustees.

   
      While the Plans are in  effect,  the  Treasurer  of the Fund is to provide
separate  written reports to the Fund's Board of Trustees at least quarterly for
its review, detailing the amount of all payments made pursuant to each Plan, the
purpose for which the payment was made and the identity of each  Recipient  that
received  any such  payment.  The report for the Class B Plan shall also include
the  Distributor's  distribution  costs  for that  quarter,  and such  costs for
previous  fiscal  periods  that have been carried  forward,  as explained in the
Prospectus and below.
    

     Those reports will be subject to the review and approval of the Independent
Trustees in the exercise of their  fiduciary  duty.  Each Plan further  provides
that while it is in effect,  the selection and  nomination of those Trustees who
are not "interested  persons" of the Trust is committed to the discretion of the
Independent  Trustees.  This does not prevent the  involvement of others in such
selection  and  nomination  if the final  decision as to any such  selection  or
nomination is approved by a majority of the Independent Trustees.

   
      Under the Plans,  no payment will be made to any  Recipient in any quarter
if the  aggregate  net asset value of all Fund shares held by the  Recipient for
itself and its  customers did not exceed a minimum  amount,  if any, that may be
determined from time to time by a majority of the Fund's  Independent  Trustees.
Initially,  the Board of Trustees  has set the fee at the maximum  rate  allowed
under the Plans and set no minimum  amount.  For the fiscal year ended September
30, 1997,  payments  under the Class A Plan totaled  $207,364,  all of which was
paid to Recipients,  including  $26,107 paid to an affiliate of the Distributor.
Any  unreimbursed  expenses  incurred by the Distributor with respect to Class A
shares for any fiscal year may not be  recovered  in  subsequent  fiscal  years.
Payments  received by the Distributor under the Class A Plan will not be used to
pay any  interest  expense,  carrying  charges,  or other  financial  costs,  or
allocation of overhead by the Distributor.
    

      The Class B and Class C Plans  allow the service fee payment to be paid by
the  Distributor  to  Recipients  in advance  for the first year such shares are
outstanding,   and  thereafter  on  a  quarterly  basis,  as  described  in  the
Prospectus.  The advance payment is based on the net asset value of shares sold.
An exchange of shares does not entitle the  Recipient to an advance  service fee
payment.  In the event Class B and Class C shares are redeemed  during the first
year such shares are outstanding, the Recipient will be obligated to repay a pro
rata  portion of the  advance of the  service  fee  payment to the  Distributor.
Pursuant to the Plans,  service fee payments by the  Distributor  to  Recipients
will be made (i) in  advance  for the first  year Class B and Class C shares are
outstanding,  following  the purchase of shares,  in an amount equal to 0.25% of
the net asset value of the shares  purchased by the  Recipient or its  customers
and (ii) thereafter,  on a quarterly basis, computed as of the close of business
each day at an annual  rate of 0.25% of the  average  daily  net asset  value of
Class B and Class C shares held in accounts of the Recipient or its customers.
   
Payments  made under the Class B Plan for the year  ended  September  30,  1997
totaled  $47,538, of  which  $43,231  was  retained  by  the  Distributor  as
reimbursement for Class B  distribution-related  expenses and sales commissions.
For the year ended  September  30,  1997,  payments  made under the Class C Plan
totalled  $119,537, of  which  $52,002  was  retained  by  the  Distributor  as
reimbursement for Class C Distribution-related expenses and sales commissions.
    

      Although  the Class B and Class C Plans permit the  Distributor  to retain
both the asset-based sales charges and the service fee on such shares, or to pay
Recipients the service fee on a quarterly basis without payment in advance,  the
Distributor presently intends to pay the service fee to Recipients in the manner
described  above. A minimum holding period may be established  from time to time
under the Class B and Class C Plans by the Board.  Initially,  the Board has set
no minimum  holding  period.  All payments under the Class B Plan are subject to
the limitations  imposed by the Rules of Conduct of the National  Association of
Securities  Dealers,  Inc. on payments of asset-based  sales charges and service
fees.

      The  Class  B  and  Class  C  Plans  provide  for  the  Distributor  to be
compensated at a flat rate, whether the Distributor's  distribution expenses are
more or less  than  the  amounts  paid  by the  Fund  during  that  period.  The
Distributor  retains the asset-based sales charge on Class B shares  outstanding
for less  than 6 years.  As to  Class C  shares,  the  Distributor  retains  the
asset-based  sales charge during the first year shares are  outstanding and pays
the asset-based  sales charge as an ongoing  commission to the dealer on Class C
shares  outstanding  for more than a year or more. Such payments are made to the
Distributor in recognition  that the Distributor  (i) pays sales  commissions to
authorized  brokers and dealers at the time of sale and pays  service  fees,  as
described  in the  Prospectus,  (ii) may  finance  such  commissions  and/or the
advance of the service  fee payment to  Recipients  under  those  Plans,  or may
provide such  financing  from its own  resources,  or from an  affiliate,  (iii)
employs personnel to support distribution of shares, and (iv) may bear the costs
of sales literature, advertising and prospectuses (other than those furnished to
current  shareholders)  and state "blue sky" registration fees and certain other
distribution expenses.

ABOUT YOUR ACCOUNT

How To Buy Shares

     Alternative Sales  Arrangements - Class A, Class B and Class C Shares.  The
availability of three classes of shares permits an investor to choose the method
of purchasing  shares that is more  beneficial to the investor  depending on the
amount of the purchase,  the length of time the investor  expects to hold shares
and other relevant  circumstances.  Investors should understand that the purpose
and function of the  deferred  sales  charge and  asset-based  sales charge with
respect to Class B and Class C shares are the same as those of the initial sales
charge with respect to Class A shares.  Any salesperson or other person entitled
to  receive   compensation  for  selling  Fund  shares  may  receive   different
compensation with respect to one class of shares than the other. The Distributor
will not accept any order for  $500,000  or more of Class B shares or $1 million
or more of Class C shares on behalf of a single  investor (not including  dealer
"street  name"  or  omnibus   accounts)   because  generally  it  will  be  more
advantageous for that investor to purchase Class A shares of the Fund instead.

      The three  classes  of  shares  each  represent  an  interest  in the same
portfolio investments of the Fund. However, each class has different shareholder
privileges  and  features.  The net income  attributable  to Class B and Class C
shares and the  dividends  payable  on such  Class B and Class C shares  will be
reduced by  incremental  expenses  borne  solely by that  class,  including  the
asset-based sales charge to which Class B and Class C shares are subject.

      The  conversion  of Class B shares  to Class A shares  after  six years is
subject to the  continuing  availability  of a private  letter  ruling  from the
Internal Revenue Service, or an opinion of counsel or tax adviser, to the effect
that the  conversion  of Class B shares does not  constitute a taxable event for
the holder under Federal  income tax law. If such a revenue ruling or opinion is
no longer available, the automatic conversion feature may be suspended, in which
event no further conversions of Class B shares would occur while such suspension
remained in effect.  Although Class B shares could then be exchanged for Class A
shares on the basis of relative net asset value of the two classes,  without the
imposition of a sales charge or fee, such  exchange  could  constitute a taxable
event for the holder, and absent such exchange, Class B shares might continue to
be subject to the asset-based sales charge for longer than six years.

      The  methodology  for  calculating  the net  asset  value,  dividends  and
distributions  of the Fund's Class A, Class B and Class C shares  recognizes two
types of expenses.  General  expenses  that do not pertain  specifically  to any
class  are  allocated  pro  rata to the  shares  of  each  class,  based  on the
percentage  of the net assets of such class to the Fund's total net assets,  and
then  equally to each  outstanding  share  within a given  class.  Such  general
expenses  include (i) management  fees, (ii) legal,  bookkeeping and audit fees,
(iii)  printing  and  mailing  costs  of  shareholder   reports,   Prospectuses,
Statements  of   Additional   Information   and  other   materials  for  current
shareholders,  (iv) fees to unaffiliated Trustees, (v) custodian expenses,  (vi)
share issuance costs,  (vii)  organization and start-up costs,  (viii) interest,
taxes  and  brokerage  commissions,  and (ix)  non-recurring  expenses,  such as
litigation costs.  Other expenses that are directly  attributable to a class are
allocated  equally to each  outstanding  share within that class.  Such expenses
include (a)  Distribution  and Service Plan fees, (b)  incremental  transfer and
shareholder  servicing agent fees and expenses,  (c)  registration  fees and (d)
shareholder  meeting  expenses,  to the extent that such  expenses  pertain to a
specific class rather than to the Fund as a whole.

   
     Determination of Net Asset Values Per Share. The net asset values per share
of Class A,  Class B and  Class C shares  of the Fund are  determined  as of the
close of business of The New York Stock  Exchange (the  "Exchange")  on each day
that the  Exchange  is open by  dividing  the  value of the  Fund's  net  assets
attributable  to that Class by the  number of shares of that class  outstanding.
The Exchange  normally closes at 4:00 P.M., New York time, but may close earlier
on some days (for  example,  in case of weather  emergencies  or on days falling
before a holiday).  The  Exchange's  most recent annual  announcement  (which is
subject to change)  states that it will close on New Year's Day,  Martin  Luther
King, Jr. Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence  Day,
Labor Day,  Thanksgiving Day and Christmas Day. It may also close on other days.
Dealers other than Exchange members may conduct trading in Municipal  Securities
on  certain  days on which  the  Exchange  is  closed  (including  weekends  and
holidays) or after 4:00 P.M. on a regular  business day.  Because the Fund's net
asset values will not be  calculated  on those days,  the Fund's net asset value
per share may be significantly  affected on such days when  shareholders may not
purchase or redeem shares.

      The Board of Trustees has established  procedures for the valuation of the
Fund's securities,  generally as follows: (i) long-term debt securities having a
remaining maturity in excess of 60 days are valued based on the mean between the
"bid" and "ask"asked"  prices determined by a portfolio pricing service approved
by the Board of  Trustees or  obtained  by the  Manager  from two active  market
makers in the  security  on the basis of  reasonable  inquiry;  (ii) a non-money
market fund will value (a) debt instruments that had a maturity of more than 397
days when issued,  (b) debt  instruments that had a maturity of 397 days or less
when  issued  and have a  remaining  maturity  in  excess  of 60  days,  and (c)
non-money  market type debt  instruments that had a maturity of 397 days or less
when  issued and have a  remaining  maturity of sixty days or less , at the mean
between "bid" and "ask"asked" prices determined by a pricing service approved by
the Fund's  Board of Trustees or, if  unavailable,  obtained by the Manager from
two active  market  makers in the security on the basis of  reasonable  inquiry;
(iii) money market-type debt securities held by a non-money market fund that had
a maturity of less than 397 days when  issued that have a remaining  maturity of
60 days or less and debt  instruments  held by a money  market  fund that have a
remaining  maturity of 397 days or less,  shall be valued at cost,  adjusted for
amortization  of  premiums  and  accretion  of  discounts;  and (iv)  securities
(including restricted securities) not having readily-available market quotations
are valued at fair value determined under the Board's procedures. If the Manager
is unable to locate two market  makers  willing to give quotes (see (i) and (ii)
above),  the  security  may be priced at the mean  between the "bid" and "asked"
prices  provided by a single  active market maker (which in certain cases may be
the "bid" price if no "asked" price is  available)  provided that the Manager is
satisfied  that the firm  rendering  the quotes is reliable  and that the quotes
reflect the current market value.
    

      In the  case of  Municipal  Securities,  U.S.  Government  securities  and
corporate  bonds,  when last sale information is not generally  available,  such
pricing procedures may include "matrix" comparisons to the prices for comparable
instruments on the basis of quality,  yield, maturity, and other special factors
involved  (such as the  tax-exempt  status  of the  interest  paid by  Municipal
Securities).  The  Manager  may use  pricing  services  approved by the Board of
Trustees to price any of the types of securities  described  above.  The Manager
will monitor the accuracy of such pricing services,  which may include comparing
prices  used for  portfolio  evaluation  to  actual  sales  prices  of  selected
securities.

   
      Puts,  calls,  Interest Rate Futures and Municipal  Bond Index Futures are
valued at the last  sales  price on the  principal  exchange  on which  they are
traded or on NASDAQ, as applicable,  as determined by a pricing service approved
by the Board of  Trustees  or by the  Manager.  If there were no sales that day,
value shall be the last sale price on the preceding  trading day if it is within
the spread of the closing "bid" and "asked" prices on the principal  exchange or
on NASDAQ on the valuation  date,  or, if not,  value shall be the closing "bid"
price on the principal  exchange or on NASDAQ on the valuation date. If the put,
call or future is not traded on an exchange or on NASDAQ,  it shall be valued at
the mean  between  "bid" and "asked"  prices  obtained  by the Manager  from two
active  market  makers  (which in  certain  cases  may be the "bid"  price if no
"asked" price is available).
    

      When the Fund writes an option, an amount equal to the premium received is
included in the Fund's  Statement of Assets and Liabilities as an asset,  and an
equivalent credit is included in the liability  section.  The credit is adjusted
("marked-to-market") to reflect the current market value of the call or put.

   
In determining the Fund's gain on  investments,  if a call or put written by the
Fund is exercised, the proceeds are increased by the premium received. If a call
or put  written  by the Fund  expires,  the Fund has a gain in the amount of the
premium; if the Fund enters into a closing purchase transaction,  it will have a
gain or loss,  depending  on whether the premium  received was more or less than
the cost of the closing  transaction.  If the Fund exercises a put it holds, the
amount the Fund receives on its sale of the underlying  investment is reduced by
the amount of the premium paid by the Fund.
    

AccountLink.  When shares are purchased through AccountLink,  each purchase must
be at least $25.  Shares  will be  purchased  on the  regular  business  day the
Distributor  is instructed to initiate the Automated  Clearing House transfer to
buy the  shares.  Dividends  will  begin to accrue on  shares  purchased  by the
proceeds of ACH  transfers on the business day the Fund  receives  Federal Funds
for the purchase  through the ACH system  before the close of The New York Stock
Exchange.  The Exchange  normally  closes at 4:00 p.m., but may close earlier on
certain days. If Federal Funds are received on a business day after the close of
the Exchange, the shares will be purchased and dividends will begin to accrue on
the next  regular  business  day after  such  Federal  Funds are  received.  The
proceeds of ACH transfers are normally received by the Fund three days after the
transfers are initiated.  The  Distributor  and the Fund are not responsible for
any delays in purchasing shares resulting from delays in ACH transmissions.

         Reduced Sales Charges. As discussed in the Prospectus,  a reduced sales
charge rate may be obtained for Class A shares under Right of  Accumulation  and
Letters of Intent  because of the  economies of sales  efforts and  reduction in
expenses realized by the Distributor,  dealers and brokers making such sales. No
sales  charge  is  imposed  in  certain  other  circumstances  described  in the
Prospectus  because  the  Distributor  or dealer or broker  incurs  little or no
selling expenses. The term "immediate family" refers to one's spouse,  children,
grandchildren,  parents,  grandparents,  parents-in-law,  brothers  and sisters,
sons-  and  daughters-in-law,  siblings,  and a  sibling's  spouse,  a  spouse's
siblings, aunts, uncles, nieces and nephews. Relations by virtue of a remarriage
(step-children, step-parents, etc.) are included.

      There is an initial sales charge on the purchase of Class A shares of each
of the Oppenheimer funds except Money Market Funds (under certain  circumstances
described herein, redemption proceeds of Money Market Fund shares may be subject
to a contingent deferred sales charge).

   
      o Letters of Intent. A Letter of Intent (referred to as a "Letter") is the
investor's  statement in writing to the Distributor of the intention to purchase
Class A shares or Class A and Class B shares of the Fund (and other  Oppenheimer
funds) during a 13-month period (the "Letter of Intent  period"),  which may, at
the investor's  request,  include purchases made up to 90 days prior to the date
of the Letter. The Letter states the investor's  intention to make the aggregate
amount of purchases of shares which,  when added to the  investor's  holdings of
shares of those funds,  will equal or exceed the amount specified in the Letter.
Purchases made by  reinvestment of dividends or  distributions  of capital gains
and  purchases  made at net asset value without sales charge do not count toward
satisfying  the amount of the Letter.  A Letter enables an investor to count the
Class A and  Class B shares to be  purchased  under  the  Letter  to obtain  the
reduced  sales charge rate on purchases of Class A shares of the Fund (and other
Oppenheimer  funds)  that  applies  under the Right of  Accumulation  to current
purchases  of Class A shares.  Each  purchase of Class A shares under the Letter
will be made at the public  offering  price  (including  the sales  charge) that
applies to a single  lump-sum  purchase  of shares in the amount  intended to be
purchased under the Letter.
    

      In  submitting a Letter,  the  investor  makes no  commitment  to purchase
shares,  but if the  investor's  purchases of shares within the Letter of Intent
period,  when added to the value (at offering price) of the investor's  holdings
of shares on the last day of that  period,  do not equal or exceed the  intended
purchase  amount,  the  investor  agrees to pay the  additional  amount of sales
charge  applicable to such  purchases,  as set forth in "Terms of Escrow," below
(as those  terms may be amended  from time to time).  The  investor  agrees that
shares  equal in value to 5% of the  intended  purchase  amount  will be held in
escrow by the Transfer Agent subject to the Terms of Escrow.  Also, the investor
agrees to be bound by the terms of the Prospectus,  this Statement of Additional
Information  and the  Application  used for such  Letter of Intent,  and if such
terms are  amended,  as they may be from time to time by the  Fund,  that  those
amendments will apply automatically to existing Letters of Intent.

      If the total eligible purchases made during the Letter of Intent period do
not equal or exceed the intended  purchase  amount,  the commissions  previously
paid to the dealer of record  for the  account  and the  amount of sales  charge
retained by the Distributor  will be adjusted to the rates  applicable to actual
total purchases.  If total eligible purchases during the Letter of Intent period
exceed the intended  purchase amount and exceed the amount needed to qualify for
the next sales charge rate reduction set forth in the applicable prospectus, the
sales charges paid will be adjusted to the lower rate,  but only if and when the
dealer  returns  to the  Distributor  the  excess of the  amount of  commissions
allowed or paid to the dealer over the amount of  commissions  that apply to the
actual amount of purchases.  The excess commissions  returned to the Distributor
will be used to purchase additional shares for the investor's account at the net
asset value per share in effect on the date of such purchase, promptly after the
Distributor's receipt thereof.

      In determining  the total amount of purchases made under a Letter,  shares
redeemed by the investor prior to the termination of the Letter of Intent period
will be deducted.  It is the  responsibility  of the dealer of record and/or the
investor  to advise the  Distributor  about the Letter in placing  any  purchase
orders  for the  investor  during  the  Letter  of  Intent  period.  All of such
purchases must be made through the Distributor.

      o Terms of Escrow That Apply to Letters of Intent.

      1. Out of the initial purchase (or subsequent purchases if necessary) made
pursuant to a Letter, shares of the Fund equal in value up to 5% of the intended
purchase amount  specified in the Letter shall be held in escrow by the Transfer
Agent. For example, if the intended purchase amount is $50,000, the escrow shall
be shares valued in the amount of $2,500  (computed at the public offering price
adjusted for a $50,000 purchase).  Any dividends and capital gains distributions
on the escrowed shares will be credited to the investor's account.

      2. If the total minimum investment specified under the Letter is completed
within the thirteen- month Letter of Intent period,  the escrowed shares will be
promptly released to the investor.

      3. If, at the end of the thirteen-month  Letter of Intent period the total
purchases  pursuant  to the Letter are less than the  intended  purchase  amount
specified in the Letter,  the investor must remit to the  Distributor  an amount
equal to the difference between the dollar amount of sales charges actually paid
and the amount of sales  charges  which would have been paid if the total amount
purchased  had been made at a single  time.  Such sales charge  adjustment  will
apply to any shares  redeemed  prior to the  completion  of the Letter.  If such
difference  in sales charges is not paid within twenty days after a request from
the Distributor or the dealer,  the Distributor  will,  within sixty days of the
expiration  of the Letter,  redeem the number of escrowed  shares  necessary  to
realize such difference in sales charges.  Full and fractional  shares remaining
after such redemption will be released from escrow.  If a request is received to
redeem escrowed shares prior to the payment of such additional sales charge, the
sales charge will be withheld from the redemption proceeds.

      4. By  signing  the  Letter,  the  investor  irrevocably  constitutes  and
appoints the Transfer Agent as  attorney-in-fact to surrender for redemption any
or all escrowed shares.
   
      5. The shares  eligible for  purchase  under the Letter (or the holding of
which may be counted toward  completion of a Letter)  include (a) Class A shares
sold with a front-end  sales charge or subject to a Class A contingent  deferred
sales charge,  (b) Class B shares of other Oppenheimer funds acquired subject to
a contingent  deferred sales charge,  and (c) Class A or Class B shares acquired
in exchange for either (i) Class A shares sold with a front-end  sales charge of
one of the other  Oppenheimer  funds that were acquired  subject to a contingent
deferred  sales  charge or (ii)  Class B shares of one of the other  Oppenheimer
funds that were acquired subject to a contingent deferred sales charge.
    

      6. Shares held in escrow  hereunder  will  automatically  be exchanged for
shares of another  fund to which an exchange is  requested,  as described in the
section of the Prospectus entitled "How to Exchange Shares," and the escrow will
be transferred to that other
fund.

   
Asset Builder Plans.  To establish an Asset Builder Plan from a bank account,  a
check  (minimum $25) for the initial  purchase must  accompany the  application.
Shares  purchased by Asset  Builder Plan payments from bank accounts are subject
to the redemption  restrictions for recent  purchases  described in "How To Sell
Shares," in the  Prospectus.  Asset  Builder Plans also enable  shareholders  of
Oppenheimer Cash Reserves to use those accounts for monthly automatic  purchases
of shares of up to four other Oppenheimer  funds. If you make payments from your
bank  account  to  purchase  shares  of the  Fund,  your  bank  account  will be
automatically  debited  normally  four  to  five  business  days  prior  to  the
investment dates selected in the Account  Application.  Neither the Distributor,
the  Transfer  Agent  nor the  Fund  shall  be  responsible  for any  delays  in
purchasing shares resulting from delays in ACH transmission.
    

      There is a front-end  sales charge on the purchase of certain  Oppenheimer
funds,  or a contingent  deferred sales charge may apply to shares  purchased by
Asset Builder payments.  An application should be obtained from the Distributor,
completed  and  returned,  and a prospectus  of the selected  fund(s)  should be
obtained from the Distributor or your financial  advisor before initiating Asset
Builder payments.  The amount of the Asset Builder  investment may be changed or
the  automatic  investments  may be  terminated  at any time by  writing  to the
Transfer Agent. A reasonable  period  (approximately  15 days) is required after
the Transfer  Agent's  receipt of such  instructions to implement them. The Fund
reserves the right to amend,  suspend, or discontinue offering such plans at any
time without prior notice.

Cancellation of Purchase Orders.  Cancellation of purchase orders for the Fund's
shares (for  example,  when a purchase  check is  returned  to the Fund  unpaid)
causes a loss to be incurred  when the net asset  value of the Fund's  shares on
the  cancellation  date is less than on the purchase date. That loss is equal to
the amount of the  decline in the net asset  value per share  multiplied  by the
number of shares in the purchase  order.  The investor is  responsible  for that
loss. If the investor fails to compensate the Fund for the loss, the Distributor
will do so. The Fund may reimburse the  Distributor for that amount by redeeming
shares from any account  registered in that investor's  name, or the Fund or the
Distributor may seek other redress.

Checkwriting. When a check is presented to the Bank for clearance, the Bank will
ask the Fund to redeem a sufficient  number of full and fractional shares in the
shareholder's  account  to cover  the  amount of the  check.  This  enables  the
shareholder to continue  receiving  dividends on those shares until the check is
presented to the Fund. Checks may not be presented for payment at the offices of
the Bank or the Fund's  Custodian.  This  limitation  does not affect the use of
checks  for the  payment  of bills or to obtain  cash at other  banks.  The Fund
reserves  the right to  amend,  suspend  or  discontinue  offering  checkwriting
privileges at any time without prior notice.

      By choosing the Checkwriting  privilege,  whether you do so by signing the
Account  Application  or by  completing a  Checkwriting  card,  the  individuals
signing (1) represent that they are either the registered owner(s) of the shares
of the Fund, or are an officer,  general partner,  trustee or other fiduciary or
agent,  as  applicable,  duly  authorized  to act on behalf  of such  registered
owner(s);  (2) authorize the Fund, its Transfer Agent and any bank through which
the Fund's drafts  ("checks") are payable (the "Bank"),  to pay all checks drawn
on the Fund account of such  person(s)  and to effect a redemption of sufficient
shares  in that  account  to cover  payment  of such  checks;  (3)  specifically
acknowledge(s)  that if you choose to permit a single  signature on checks drawn
against joint accounts,  or accounts for corporations,  partnerships,  trusts or
other entities, the signature of any one signatory on a check will be sufficient
to authorize  payment of that check and redemption  from an account even if that
account is  registered in the names of more than one person or even if more than
one authorized signature appears on the Checkwriting card or the Application, as
applicable;  and  (4)  understand(s)  that  the  Checkwriting  privilege  may be
terminated  or amended at any time by the Fund and/or the Bank and neither shall
incur  any  liability  for  such  amendment  or  termination  or  for  effecting
redemptions to pay checks reasonably believed to be genuine, or for returning or
not paying checks which have not been accepted for any reason.

How to Sell Shares

     Information on how to sell shares of the Fund is stated in the  Prospectus.
The information  below  supplements the terms and conditions for redemptions set
forth in the Prospectus.

      o Selling Shares by Wire. The wire of redemptions  proceeds may be delayed
if the Fund's  custodian  bank is not open for  business  on a day when the Fund
would normally  authorize the wire to be made,  which is usually the Fund's next
regular business day following the redemption. In those circumstances,  the wire
will not be  transmitted  until the next bank  business day on which the Fund is
open for business.  No dividends will be paid on the proceeds of redeemed shares
awaiting transfer by wire.

         o Involuntary  Redemptions.  The Fund's Board of Trustees has the right
to cause the  involuntary  redemption  of the shares  held in any account if the
aggregate  net asset  value of those  shares is less than  $1,000 or such lesser
amount  as the  Board  may  fix.  The  Board of  Trustees  will  not  cause  the
involuntary  redemption of shares in an account if the aggregate net asset value
of the shares has fallen below the stated  minimum  solely as a result of market
fluctuations. Should the Board elect to exercise this right, it may also fix, in
accordance with the Investment  Company Act, the  requirements for any notice to
be given to the  shareholders  in question (not less than 30 days), or the Board
may set requirements for granting permission to the shareholders to increase the
investment,  and set other terms and  conditions so that the shares would not be
involuntarily redeemed.
    

      o Payments  "In Kind".  The  Prospectus  states  that  payment  for shares
tendered  for  redemption  is  ordinarily  made in cash.  However,  the Board of
Trustees of the Trust may  determine  that it would be  detrimental  to the best
interests  of the  remaining  shareholders  of the  Fund  to make  payment  of a
redemption  order wholly or partly in cash.  In that case,  the Fund may pay the
redemption  proceeds  in  whole  or in  part  by a  distribution  "in  kind"  of
securities  from the portfolio of the Fund, in lieu of cash, in conformity  with
applicable  rules of the  Securities  and  Exchange  Commission.  The  Trust has
elected to be governed by Rule 18f-1 under the Investment  Company Act, pursuant
to which the Fund is obligated to redeem  shares solely in cash up to the lesser
of $250,000 or 1% of the net assets of the Fund during any 90-day period for any
one shareholder. If shares are redeemed in kind, the redeeming shareholder might
incur brokerage or other costs in selling the securities for cash. The method of
valuing  securities  used to make  redemptions  in kind  will be the same as the
method the Fund uses to value its  portfolio  securities  described  above under
"Determination of Net Asset Values Per Share" and that valuation will be made as
of the time the redemption price is determined.

   
     Reinvestment  Privilege.  Within six months of a redemption,  a shareholder
may reinvest all or part of the  redemption  proceeds of (i) Class A shares that
you purchase  subject to an initial sales charge or Class A contingent  deferred
sales charge which was paid, or (ii) Class B
    
     shares that were  subject to the Class B contingent  deferred  sales charge
when redeemed. The reinvestment may be made without sales charge only in Class A
shares of the Fund or any of the other  Oppenheimer  funds into which  shares of
the Fund are exchangeable as described in "How to Exchange Shares" below, at the
net asset value next computed after the Transfer Agent receives the reinvestment
order.  This  reinvestment  privilege  does not  apply to  Class C  shares.  The
shareholder  must  ask  the  Distributor  for  that  privilege  at the  time  of
reinvestment.  Any capital gain that was realized  when the shares were redeemed
is taxable,  and  reinvestment  will not alter any capital  gains tax payable on
that gain.  If there has been a capital loss on the  redemption,  some or all of
the loss may not be tax  deductible,  depending  on the timing and amount of the
reinvestment.  Under the Internal  Revenue Code, if the  redemption  proceeds of
Fund  shares on which a sales  charge was paid are  reinvested  in shares of the
Fund or another of the Oppenheimer  funds within 90 days of payment of the sales
charge, the shareholder's basis in the shares of the Fund that were redeemed may
not include the amount of the sales charge  paid.  That would reduce the loss or
increase the gain  recognized  from the  redemption.  However,  in that case the
sales  charge  would  be  added  to the  basis  of the  shares  acquired  by the
reinvestment of the redemption  proceeds.  The Fund may amend,  suspend or cease
offering this reinvestment privilege at any time as to shares redeemed after the
date of such amendment, suspension or cessation.

Transfers  of Shares.  Shares are not  subject  to the  payment of a  contingent
deferred  sales  charge  of any  class  at the time of  transfer  to the name of
another person or entity  (whether the transfer  occurs by absolute  assignment,
gift or bequest,  not  involving,  directly or indirectly,  a public sale).  The
transferred shares will remain subject to the contingent  deferred sales charge,
calculated as if the transferee  shareholder had acquired the transferred shares
in the same manner and at the same time as the transferring shareholder. If less
than all shares held in an account are transferred,  and some but not all shares
in the  account  would be  subject  to a  contingent  deferred  sales  charge if
redeemed at the time of transfer,  the  priorities  described in the  Prospectus
under  "How to Buy  Shares"  for the  imposition  of the  Class B or the Class C
contingent  deferred sales charge will be followed in  determining  the order in
which shares are transferred.

Special  Arrangements  for  Repurchase  of Shares from Dealers and Brokers.  The
Distributor is the Fund's agent to repurchase its shares from authorized dealers
or brokers on behalf of their  customers.  The  shareholder  should  contact the
broker or dealer to arrange this type of redemption.  The  repurchase  price per
share will be the net asset value next computed after the  Distributor  receives
an order placed by the dealer or broker, except that if the Distributor receives
a repurchase order from a dealer or broker after the close of The New York Stock
Exchange on a regular business day, it will be processed at that day's net asset
value if the order was received by the dealer or broker from its customers prior
to the time the Exchange closes  (normally that is 4:00 p.m., but may be earlier
on some days) and the order was  transmitted to and received by the  Distributor
prior to its close of business that day (normally  5:00 P.M.).  Ordinarily,  for
accounts redeemed by a broker-dealer under this procedure,  payment will be made
within  three  business  days  after  the  shares  have been  redeemed  upon the
Distributor's  receipt of the required redemption documents in proper form, with
the signature(s) of the registered owners guaranteed on the redemption documents
as described in the Prospectus.

   
Automatic  Withdrawal and Exchange  Plans.  Investors  owning shares of the Fund
valued at $5,000  or more can  authorize  the  Transfer  Agent to redeem  shares
(minimum $50) automatically on a monthly, quarterly, semi-annual or annual basis
under an Automatic  Withdrawal Plan. Shares will be redeemed three business days
prior to the date  requested  by the  shareholder  for  receipt of the  payment.
Automatic withdrawals of up to $1,500 per month may be requested by telephone if
payments are to be made by check payable to all  shareholders of record and sent
to the  address  of record  for the  account  (and if the  address  has not been
changed  within  the  prior  30  days).   Required  minimum  distributions  from
OppenheimerFunds-sponsored  retirement  plans may not be arranged on this basis.
Payments  are  normally  made by  check,  but  shareholders  having  AccountLink
privileges  (see "How To Buy Shares") may arrange to have  Automatic  Withdrawal
Plan payments transferred to the bank account designated on the OppenheimerFunds
New  Account  Application  or  signature-guaranteed   instructions.  Shares  are
normally redeemed  pursuant to an Automatic  Withdrawal Plan three business days
before the date you select in the Account Application.  If a contingent deferred
sales charge applies to the redemption,  the amount of the check or payment will
be reduced  accordingly.  The Fund cannot guarantee  receipt of a payment on the
date requested and reserves the right to amend,  suspend or discontinue offering
such  plans at any time  without  prior  notice.  Because  of the  sales  charge
assessed  on Class A share  purchases,  shareholders  should  not  make  regular
additional  Class  A  share  purchases  while   participating  in  an  Automatic
Withdrawal  Plan.  Class  B  and  Class  C  shareholders  should  not  establish
withdrawal  plans because of the  imposition of the  contingent  deferred  sales
charge on such withdrawals (except where the contingent deferred sales charge is
waived as  described  in the  Prospectus  under  "Waivers of Class B and Class C
Sales Charges").
    

      By requesting an Automatic  Withdrawal or Exchange Plan,  the  shareholder
agrees to the terms and conditions applicable to such plans, as stated below, as
well as the Prospectus. These provisions may be amended from time to time by the
Fund and/or the Distributor.  When adopted,  such amendments will  automatically
apply to existing Plans.

      o Automatic Exchange Plans.  Shareholders can authorize the Transfer Agent
(on the OppenheimerFunds  Application or  signature-guaranteed  instructions) to
exchange a  pre-determined  amount of shares of the Fund for shares (of the same
class)  of  other  Oppenheimer  funds  automatically  on a  monthly,  quarterly,
semi-annual or annual basis under an Automatic Exchange Plan. The minimum amount
that may be exchanged to each other fund  account is $25.  Exchanges  made under
these plans are subject to the restrictions that apply to exchanges as set forth
in "How to Exchange  Shares" in the  Prospectus  and below in this  Statement of
Additional Information.

     o Automatic  Withdrawal Plans. Fund shares will be redeemed as necessary to
meet  withdrawal  payments.  Shares  acquired  without  a sales  charge  will be
redeemed  first and thereafter  shares  acquired with  reinvested  dividends and
capital gains  distributions will be redeemed next,  followed by shares acquired
with a sales  charge,  to the  extent  necessary  to make  withdrawal  payments.
Depending upon the amount withdrawn,  the investor's  principal may be depleted.
Payments  made under such plans should not be considered as a yield or income on
your investment.  It may not be desirable to purchase additional shares of Class
A shares while maintaining  automatic  withdrawals  because of the sales charges
that apply to purchases when made.  Accordingly,  a shareholder normally may not
maintain  an  Automatic  Withdrawal  Plan while  simultaneously  making  regular
purchases of Class A shares.

      The Transfer Agent will  administer the  investor's  Automatic  Withdrawal
Plan (the "Plan") as agent for the investor (the  "Planholder") who executed the
Plan authorization and application  submitted to the Transfer Agent. Neither the
Fund nor the Transfer  Agent shall incur any liability to the Planholder for any
action taken or omitted by the Transfer  Agent in good faith to  administer  the
Plan.  Certificates  will not be issued for shares of the Fund purchased for and
held under the Plan,  but the Transfer  Agent will credit all such shares to the
account of the  Planholder  on the records of the Fund.  Any share  certificates
held by a Planholder  may be  surrendered  unendorsed to the Transfer Agent with
the Plan  application so that the shares  represented by the  certificate may be
held under the Plan.

      For  accounts  subject to Automatic  Withdrawal  Plans,  distributions  of
capital gains must be  reinvested  in shares of the Fund,  which will be done at
net asset value without a sales charge.  Dividends on shares held in the account
may be paid in cash or reinvested.

      Redemptions of shares needed to make  withdrawal  payments will be made at
the net asset  value per share  determined  on the  redemption  date.  Checks or
AccountLink  payments  of the  proceeds  of Plan  withdrawals  will  normally be
transmitted  three  business  days prior to the date selected for receipt of the
payment  (receipt  of  payment  on the  date  selected  cannot  be  guaranteed),
according to the choice specified in writing by the Planholder.

      The amount and the  interval of  disbursement  payments and the address to
which  checks  are to be mailed or  AccountLink  payments  are to be sent may be
changed at any time by the  Planholder  by writing to the  Transfer  Agent.  The
Planholder  should allow at least two weeks' time in mailing  such  notification
for the requested  change to be put in effect.  The Planholder may, at any time,
instruct the Transfer Agent by written notice (in proper form in accordance with
the requirements of the  then-current  Prospectus of the Fund) to redeem all, or
any part of, the shares held under the Plan.  In that case,  the Transfer  Agent
will redeem the number of shares  requested  at the net asset value per share in
effect in accordance with the Fund's usual redemption procedures and will mail a
check for the proceeds to the Planholder.

      The Plan may be terminated at any time by the Planholder by writing to the
Transfer  Agent. A Plan may also be terminated at any time by the Transfer Agent
upon receiving  directions to that effect from the Fund. The Transfer Agent will
also terminate a Plan upon receipt of evidence  satisfactory  to it of the death
or  legal  incapacity  of the  Planholder.  Upon  termination  of a Plan  by the
Transfer Agent or the Fund,  shares that have not been redeemed from the account
will be held in  uncertificated  form  in the  name of the  Planholder,  and the
account will continue as a dividend-reinvestment,  uncertificated account unless
and until proper  instructions  are received  from the  Planholder or his or her
executor or guardian, or other authorized person.

      To use shares held under the Plan as collateral for a debt, the Planholder
may  request  issuance  of a portion of the shares in  certificated  form.  Upon
written  request from the  Planholder,  the Transfer  Agent will  determine  the
number of shares  for which a  certificate  may be issued  without  causing  the
withdrawal checks to stop because of exhaustion of uncertificated  shares needed
to  continue  payments.   However,  should  such  uncertificated  shares  become
exhausted, Plan withdrawals will terminate.

      If the Transfer  Agent ceases to act as transfer  agent for the Fund,  the
Planholder will be deemed to have appointed any successor  transfer agent to act
as agent in administering the Plan.

How To Exchange Shares

      As stated in the Prospectus,  shares of a particular  class of Oppenheimer
funds having more than one class of shares may be  exchanged  only for shares of
the same class of other Oppenheimer funds.  Shares of the Oppenheimer funds that
have a single class without a class  designation are deemed "Class A" shares for
this purpose.  All of the Oppenheimer funds offer Class A, B and C shares except
Oppenheimer Money Market Fund, Inc.,  Centennial Money Market Trust,  Centennial
Tax Exempt Trust,  Centennial  Government Trust,  Centennial New York Tax Exempt
Trust,  Centennial  California Tax Exempt Trust,  Centennial America Fund, L.P.,
and Daily Cash  Accumulation  Fund,  Inc.,  which only offer  Class A shares and
Oppenheimer Main Street California  Municipal Fund which only offers Class A and
Class B shares,  (Class B and Class C shares of  Oppenheimer  Cash  Reserves are
generally  available  only by  exchange  from the same  class of shares of other
Oppenheimer funds or through OppenheimerFunds sponsored 401(k) plans). A current
list  showing  which funds  offer  which  classes can be obtained by calling the
Distributor at 1-800-525-7048.

   
      For accounts established on or before March 8, 1996 holding Class M shares
of  Oppenheimer  Bond Fund for Growth,  Class M shares can be exchanged only for
Class A shares  of other  Oppenheimer  funds .  Exchanges  to Class M shares  of
Oppenheimer  Bond  Fund  for  Growth  are  permitted  from  Class  A  shares  of
Oppenheimer  Money Market Fund,  Inc. or  Oppenheimer  Cash  Reserves  that were
acquired by exchange from Class M shares. Otherwise no exchanges of any class of
any Oppenheimer fund into Class M shares are permitted.
    

       
      Class A shares of  Oppenheimer  funds may be  exchanged at net asset value
for shares of any Money Market Fund.  Shares of any Money Market Fund  purchased
without a sales charge may be exchanged for shares of Oppenheimer  funds offered
with a sales charge upon payment of the sales charge (or, if applicable,  may be
used to purchase  shares of Oppenheimer  funds subject to a contingent  deferred
sales charge).  However, shares of Oppenheimer Money Market Fund, Inc. purchased
with the  redemption  proceeds of shares of other mutual funds (other than funds
managed by the Manager or its subsidiaries)  redeemed within the 12 months prior
to that purchase may  subsequently be exchanged for shares of other  Oppenheimer
funds without being subject to an initial or contingent  deferred  sales charge,
whichever  is  applicable.  To qualify for that  privilege,  the investor or the
investor's  dealer must notify the Distributor of eligibility for this privilege
at the time the shares of  Oppenheimer  Money Market Fund,  Inc. are  purchased,
and, if requested, must supply proof of entitlement to this privilege.

   
      Shares of the Fund acquired by reinvestment of dividends or  distributions
from any of the other  Oppenheimer  funds or from any unit investment  trust for
which  reinvestment  arrangements  have been made  with the  Distributor  may be
exchanged  at net asset  value for shares of any of the  Oppenheimer  funds.  No
contingent  deferred sales charge is imposed on exchanges of shares of any class
purchased subject to a contingent deferred sales charge.  However,  when Class A
shares  acquired  by  exchange  of Class A shares  of  other  Oppenheimer  funds
purchased  subject to a Class A  contingent  deferred  sales charge are redeemed
within 12 months of the end of the calendar month of the initial purchase of the
exchanged Class A shares (18 months if the shares were initially purchased prior
to May 1, 1997), the Class A contingent  deferred sales charge is imposed on the
redeemed  shares.  (See  "Class  A  Contingent  Deferred  Sales  Charge"  in the
Prospectus).  The Class B contingent deferred sales charge is imposed on Class B
shares acquired by exchange if they are redeemed within six years of the initial
purchase of the exchanged Class B shares. The Class C contingent  deferred sales
charge is imposed on Class C shares  acquired by  exchange if they are  redeemed
within 12 months of the initial purchase of the exchanged Class C shares.
    

      When Class B or Class C shares are  redeemed  to effect an  exchange,  the
priorities described in "How To Buy Shares" in the Prospectus for the imposition
of the Class B or Class C contingent  deferred  sales charge will be followed in
determining  the order in which the shares are  exchanged.  Shareholders  should
take into  account the effect of any exchange on the  applicability  and rate of
any  contingent  deferred  sales charge that might be imposed in the  subsequent
redemption  of remaining  shares.  Shareholders  owning  shares of more than one
Class must specify  whether they intend to exchange  Class A, Class B or Class C
shares.

      The Fund  reserves  the  right to reject  telephone  or  written  exchange
requests  submitted  in bulk by anyone on behalf of more than one  account.  The
Fund  may  accept  requests  for  exchanges  of up to 50  accounts  per day from
representatives  of  authorized  dealers  that  qualify for this  privilege.  In
connection with any exchange request, the number of shares exchanged may be less
than the number  requested if the exchange or the number requested would include
shares  subject to a restriction  cited in the  Prospectus or this  Statement of
Additional  Information or would include  shares covered by a share  certificate
that is not tendered with the request. In those cases, only the shares available
for exchange without restriction will be exchanged.

   
      When  exchanging  shares by telephone,  a shareholder  must either have an
existing account in, or have obtained and  acknowledged  receipt of a prospectus
of, the fund to which the exchange is to be made. For full or partial  exchanges
of an account made by  telephone,  any special  account  features  such as Asset
Builder Plans and Automatic Withdrawal Plans will be switched to the new account
unless the Transfer Agent is instructed  otherwise.  If all telephone  lines are
busy (which  might occur,  for example,  during  periods of  substantial  market
fluctuations),  shareholders might not be able to request exchanges by telephone
and would have to submit written exchange requests.
    

     Shares  to be  exchanged  are  redeemed  on the  regular  business  day the
Transfer  Agent  receives  an exchange  request in proper form (the  "Redemption
Date").  Normally,  shares  of the  fund to be  acquired  are  purchased  on the
Redemption  Date,  but such  purchases  may be delayed by either fund up to five
business days if it determines  that it would be  disadvantaged  by an immediate
transfer  of the  redemption  proceeds.  The Fund  reserves  the  right,  in its
discretion,  to  refuse  any  exchange  request  that may  disadvantage  it (for
example,  if the  receipt of  multiple  exchange  requests  from a dealer  might
require the  disposition  of portfolio  securities  at a time or at a price that
might be disadvantageous to the Fund).

      The different  Oppenheimer  funds  available  for exchange have  different
investment objectives,  policies and risks, and a shareholder should assure that
the Fund selected is  appropriate  for his or her investment and should be aware
of the tax  consequences  of an exchange.  For federal  income tax purposes,  an
exchange  transaction  is  treated as a  redemption  of shares of one fund and a
purchase of shares of another.  "Reinvestment  Privilege," above, discusses some
of the tax  consequences of  reinvestment of redemption  proceeds in such cases.
The  Fund,  the  Distributor,  and the  Transfer  Agent are  unable  to  provide
investment,  tax or legal advice to a shareholder in connection with an exchange
request or any other investment transaction.

Dividends, Capital Gains and Taxes

     Dividends and  Distributions.  Dividends  will be payable on shares held of
record  at the time of the  previous  determination  of net asset  value.  Daily
dividends will not be declared or paid on  newly-purchased  shares until Federal
Funds (funds  credited to a member bank's  account at the Federal  Reserve Bank)
are  available  from the purchase  payment for such shares.  Normally,  purchase
checks  received  from  investors  are  converted  to Federal  Funds on the next
business day. Shares purchased  through dealers or brokers normally are paid for
by the third business day following the placement of the purchase order.  Shares
redeemed through the regular redemption procedure will be paid dividends through
and  including  the day on which  the  redemption  request  is  received  by the
Transfer  Agent in proper  form.  Dividends  will be paid with respect to shares
repurchased  by a dealer or broker for three  business days  following the trade
date (i.e., to and including the day prior to settlement of the repurchase).  If
a shareholder redeems all shares in an account,  all dividends accrued on shares
held in that account will be paid together with the redemption proceeds.

      Dividends, distributions and the proceeds of the redemption of Fund shares
represented  by checks  returned to the Transfer  Agent by the Postal Service as
undeliverable will be invested in shares of Oppenheimer Money Market Fund, Inc.,
as promptly as possible  after the return of such checks to the Transfer  Agent,
to enable the investor to earn a return on otherwise idle funds.

      The amount of a class's distributions may vary from time to time depending
on market  conditions,  the  composition of the Fund's  portfolio,  and expenses
borne by the Fund or borne  separately by a class,  as described in "Alternative
Sales  Arrangements  -- Class A,  Class B and Class  C,"  above.  Dividends  are
calculated  in the same manner,  at the same time and on the same day for shares
of each class. However,  dividends on Class B and Class C shares are expected to
be lower than dividends on Class A shares as a result of the  asset-based  sales
charges  on Class B and  Class C  shares,  and will  also  differ in amount as a
consequence of any difference in net asset value between the classes.

   
Tax  Status of the  Fund's  Dividends  and  Distributions.  The Fund  intends to
qualify  under  the  Internal  Revenue  Code  during  each  fiscal  year  to pay
"exempt-interest  dividends" to its  shareholders.  Exempt-  interest  dividends
which are derived  from net  investment  income  earned by the Fund on Municipal
Securities  will be  excludable  from gross income of  shareholders  for Federal
income tax purposes. Net investment income includes the allocation of amounts of
income from the Municipal Securities in the Fund's portfolio which are free from
Federal income taxes.  This allocation will be made by the use of one designated
percentage  applied uniformly to all income dividends made during the Fund's tax
year.  Such  designation  will normally be made following the end of each fiscal
year as to income  dividends  paid in the prior year.  The  percentage of income
designated as tax-exempt  may  substantially  differ from the  percentage of the
Fund's income that was tax-exempt  for a given period.  A portion of the exempt-
interest  dividends  paid  by the  Fund  may be an item  of tax  preference  for
shareholders subject to the alternative minimum tax. All of the Fund's dividends
(excluding  capital  gains  distributions)  paid  during  1997 were  exempt from
Federal personal income taxes.  The amount of any dividends  attributable to tax
preference items for purposes of the alternative  minimum tax will be identified
when tax  information  is distributed by the Fund.  Corporate  shareholders  and
"substantial  users"  of  facilities  financed  by  Private  Activity  Municipal
Securities should see "Private Activity Municipal Securities."
    

      A shareholder receiving a dividend from income earned by the Fund from one
or more of: (1) certain taxable  temporary  investments (such as certificates of
deposit,  repurchase  agreements,  commercial  paper and obligations of the U.S.
government,  its agencies  and  instrumentalities);  (2) income from  securities
loans;  or (3) an  excess of net  short-term  capital  gain  over net  long-term
capital loss from the Fund,  treats the dividend as a receipt of either ordinary
income or long-term capital gain in the computation of gross income,  regardless
of whether the dividend is reinvested. The Fund's dividends will not be eligible
for the  dividends-received  deduction for corporations.  Shareholders receiving
Social Security  benefits should be aware that  exempt-interest  dividends are a
factor in  determining  whether such benefits are subject to Federal income tax.
Losses  realized by  shareholders  on the  redemption  of Fund shares within six
months of  purchase  (which  period  may be  shortened  by  regulation)  will be
disallowed  for Federal  income tax  purposes  to the extent of  exempt-interest
dividends received on such shares.

      Long-term  capital gains  distributions,  if any, are taxable as long-term
capital gains whether  received in cash or reinvested and regardless of how long
Fund  shares  have  been  held.  Dividends  paid by the  Fund  derived  from net
short-term capital gains are taxable to shareholders as ordinary income, whether
received in cash or  reinvested.  For  information  on "backup  withholding"  on
taxable dividends,  see "How To Sell Shares." Interest on loans used to purchase
shares of the Fund may not be deducted for Federal  income tax  purposes.  Under
rules used by the Internal  Revenue Service to determine when borrowed funds are
deemed used for the purpose of purchasing  or carrying  particular  assets,  the
purchase of Fund shares may be considered to have been made with borrowed  funds
even though the  borrowed  funds are not  directly  traceable to the purchase of
shares.

     If the  Fund  qualifies  as a  "regulated  investment  company"  under  the
Internal Revenue Code, it will not be liable for Federal income taxes on amounts
paid by it as dividends  and  distributions.  The Fund  qualified as a regulated
investment  company  in its last  fiscal  year and  intends to qualify in future
years, but reserves the right not to qualify. The Internal Revenue Code contains
a number of complex tests to determine  whether the Fund will  qualify,  and the
Fund might not meet those tests in a particular  year. For example,  if the Fund
derives 30% or more of its gross  income from the sale of  securities  held less
than three months, it may fail to qualify (see "Tax Aspects of Covered Calls and
Hedging  Instruments,"  above). If it does not qualify, the Fund will be treated
for tax purposes as an ordinary  corporation,  will receive no tax deduction for
payments of dividends and distributions made to shareholders and would be unable
to pay "exempt-interest" dividends as discussed above.

      Under the Internal  Revenue  Code,  by December 31 each year the Fund must
distribute  98% of its taxable  investment  income earned from January 1 through
December  31 of that year and 98% of its  capital  gains  realized in the period
from  November 1 of the prior year through  October 31 of the current  year,  or
else the Fund must pay an excise tax on the amounts not  distributed.  The Board
and the Manager  might  determine in a  particular  year that it might be in the
best  interest of  shareholders  for the Fund not to make  distributions  at the
required  levels and to pay the excise tax on the  undistributed  amounts.  That
would reduce the amount of income or capital gains available for distribution to
shareholders.

   
Dividend  Reinvestment  in Another Fund.  Shareholders  of the Fund may elect to
reinvest all dividends  and/or  distributions in shares of the same class of any
of the other  Oppenheimer funds (other than Oppenheimer Cash Reserves) listed in
"Reduced  Sales  Charges,"  above,  at net asset value without sales charge.  To
elect this option,  a shareholder  must notify the Transfer Agent in writing and
either must have an existing account in the fund selected for investment or must
obtain a prospectus  for that fund and an  application  from the  Distributor to
establish  an account.  The  investment  will be made at the net asset value per
share in effect at the close of business on the payable  date of the dividend or
distribution.  Dividends  and  distributions  from other  Eligible  Funds may be
invested in shares of this Fund on the same basis.
    

Additional Information About the Fund

     The  Custodian.  The Custodian of the assets of the Fund is Citibank,  N.A.
The Custodian's responsibilities include safeguarding and controlling the Fund's
portfolio securities, collecting income on the portfolio securities and handling
the  delivery  of  such  securities  to and  from  the  Fund.  The  Manager  has
represented to the Fund that the banking  relationships  between the Manager and
the Custodian  have been and will continue to be unrelated to and  unaffected by
the relationship between the Fund and the Custodian.  It will be the practice of
the Fund to deal with the  Custodian  in a manner  uninfluenced  by any  banking
relationship  the  Custodian may have with the Manager and its  affiliates.  The
Fund's cash  balances with the Custodian in excess of $100,000 are not protected
by  Federal  Deposit  Insurance.   Such  uninsured  balances  may  at  times  be
substantial.

Independent  Auditors.  The independent auditors of the Fund audit the Manager's
and the Fund's  financial  statements and perform other related audit  services.
They also act as auditors for certain other funds advised by the Manager and its
affiliates.

INDEPENDENT AUDITORS' REPORT

==============================================================================
The Board of Trustees and Shareholders of
Oppenheimer Intermediate Municipal Fund:

We have audited the accompanying statement of assets and liabilities,  including
the statement of investments,  of Oppenheimer  Intermediate Municipal Fund as of
September 30, 1997, the related statement of operations for the year then ended,
the  statements of changes in net assets for the years ended  September 30, 1997
and  1996,  and the  financial  highlights  for the  period  October  1, 1992 to
September 30, 1997. These financial  statements and financial highlights are the
responsibility  of the Fund's  management.  Our  responsibility is to express an
opinion on these  financial  statements  and financial  highlights  based on our
audits.

            We  conducted  our  audits in  accordance  with  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 at September  30, 1997 by  correspondence  with the custodian and brokers;
where  replies 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,  such financial  statements and financial highlights
present fairly, in all material respects,  the financial position of Oppenheimer
Intermediate   Municipal  Fund  at  September  30,  1997,  the  results  of  its
operations,  the changes in its net assets, and the financial highlights for the
respective  stated  periods,  in conformity with generally  accepted  accounting
principles.

divided by the monthly average of the market value of portfolio securities owned
during the period.  Securities with a maturity or expiration date at the time of
acquisition of one year or less are excluded from the calculation. Purchases and
sales of investment securities (excluding short-term  securities) for the period
ended September 30, 1997 were $48,749,221 and $31,937,283, respectively.

==============================================================================
1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer  Intermediate  Municipal  Fund (the  Fund) is a  separate  series of
Oppenheimer  Municipal  Fund,  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  maximum  current  income  exempt from
federal  income  tax for  individual  investors  that  is  consistent  with  the
preservation of capital by investing  primarily in  intermediate  term municipal
bonds. The Fund's investment  advisor is  OppenheimerFunds,  Inc. (the Manager).
The Fund  offers  Class A,  Class B and Class C 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.  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.

- ------------------------------------------------------------------------------
ALLOCATION OF INCOME,  EXPENSES, AND GAINS AND LOSSES.  Income,  expenses (other
than those  attributable to a specific class) and 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.





                   20 Oppenheimer Intermediate Municipal 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.  At September 30, 1997, the
Fund had  available  for  federal  income tax  purposes an unused  capital  loss
carryover of approximately $742,000, expiring in 2003 and 2004.

- ------------------------------------------------------------------------------
DISTRIBUTIONS TO SHAREHOLDERS.  The Fund intends to declare dividends separately
for Class A, Class B and Class C 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 premium  amortization on long-term bonds 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.

            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
period ended  September 30, 1997,  amounts have been  reclassified  to reflect a
decrease in  undistributed  net  investment  income of  $173,785,  a decrease in
accumulated  net realized  loss on  investments  of $547,316,  and a decrease in
paid-in capital of $373,531.

- ------------------------------------------------------------------------------
OTHER. Investment transactions are accounted for on the date the investments are
purchased or sold (trade date).  Original issue discount on securities purchased
is amortized  over the life of the  respective  securities  using the  effective
yield method,  in accordance  with federal  income tax  requirements.  For bonds
acquired  after April 30, 1993, on  disposition  or maturity,  taxable  ordinary
income is recognized to the extent of the lesser of gain or market discount that
would  have  accrued  over the  holding  period.  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.

3. UNREALIZED GAINS AND LOSSES ON INVESTMENTS

At September 30, 1997, net unrealized  appreciation on investments of $4,813,198
was composed of gross  appreciation  of $5,225,559,  and gross  depreciation  of
$412,361.

==============================================================================
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 0.50% on the first
$100  million of  average  annual net  assets,  0.45% on the next $150  million,
0.425%  on the next  $250  million  and  0.40% on net  assets  in excess of $500
million.

            The Manager acts as the  accounting  agent for the Fund at an annual
fee of $12,000, plus out-of-pocket costs and expenses reasonably incurred.

            For the year ended  September 30, 1997,  commissions  (sales charges
paid by investors) on sales of Class A shares totaled $173,050, of which $75,561
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 $133,554 and $57,363,  respectively,  of which $6,814 was
paid to an affiliated broker/dealer for Class B shares.





                   22 Oppenheimer Intermediate Municipal Fund

<PAGE>



==============================================================================
During the year ended  September  30, 1997,  OFDI received  contingent  deferred
sales charges of $13,462 and $8,862,  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.

            Expenses paid indirectly represent a reduction of custodian fees for
earnings on cash balances maintained by the Fund.

            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 maintaining accounts of their customers that hold
Class A shares.  During the year ended  September 30, 1997, OFDI paid $26,107 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 services  and 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 shares
and Class C shares,  as  compensation  for sales  commissions  paid from its own
resources at the time of sale and associated financing costs. OFDI also receives
a service fee of 0.25% per year as compensation for costs incurred in connection
with the personal  service and  maintenance  of accounts that hold shares of the
Fund,  including  amounts paid to brokers,  dealers,  banks and other  financial
institutions. Both fees are 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 year ended  September  30,  1997,  OFDI paid $4,191 to an  affiliated
broker/dealer  as  compensation  for Class C personal  service  and  maintenance
expenses and retained  $43,231 and $52,002,  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 September 30, 1997,
OFDI had incurred unreimbursed expenses of $167,478 for Class B and $186,693 for
Class C.

NOTES TO FINANCIAL STATEMENTS (Continued)

==============================================================================
5. 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.

            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.

==============================================================================
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  OppenheimerFunds  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
September 30, 1997.

                        APPENDIX A

      Descriptions of Ratings Categories

Municipal 

Bonds

      |X| Moody's  Investor  Services,  Inc.  The  ratings of Moody's  Investors
Service,  Inc.  ("Moody's") for Municipal Bonds are Aaa, Aa, A, Baa, Ba, B, Caa,
Ca and C.  Municipal  Bonds rated "Aaa" are judged to be of the "best  quality."
The  rating  of Aa is  assigned  to  bonds  which  are of "high  quality  by all
standards,"  but as to  which  margins  of  protection  or other  elements  make
long-term risks appear somewhat  larger than "Aaa" rated  Municipal  Bonds.  The
"Aaa" and "Aa" rated  bonds  comprise  what are  generally  known as "high grade
bonds."  Municipal  Bonds which are rated "A" by Moody's  possess many favorable
investment  attributes  and are  considered  "upper  medium grade  obligations."
Factors  giving  security  to  principal  and  interest  of A  rated  bonds  are
considered adequate,  but elements may be present which suggest a susceptibility
to  impairment  at some time in the  future.  Municipal  Bonds  rated  "Baa" are
considered  "medium grade"  obligations.  They are neither highly  protected nor
poorly secured. Interest payments and principal security appear adequate for the
present   but   certain   protective   elements   may  be   lacking  or  may  be
characteristically  unreliable  over any great  length of time.  Such bonds lack
outstanding   investment   characteristics   and  in   fact   have   speculative
characteristics  as  well.  Bonds  which  are  rated  "Ba"  are  judged  to have
speculative elements;  their future cannot be considered as well assured.  Often
the  protection  of interest and  principal  payments  may be very  moderate and
thereby  not well  safeguarded  during  both good and bad times over the future.
Uncertainty of position characterizes bonds in this class. Bonds which are rated
"B" generally lack  characteristics  of the desirable  investment.  Assurance of
interest and principal payments or of maintenance of other terms of the contract
over any long  period of time may be small.  Bonds  which are rated "Caa" are of
poor standing. Such issues may be in default or there may be present elements of
danger  with  respect  to  principal  or  interest.  Bonds  which are rated "Ca"
represent  obligations  which are speculative in a high degree.  Such issues are
often in default or have other  marked  shortcomings.  Bonds which are rated "C"
are the lowest  rated  class of bonds,  and issues so rated can be  regarded  as
having extremely poor prospects of ever attaining any real investment  standing.
Those bonds in the Aa, A, Baa, Ba and B groups which  Moody's  believes  possess
the strongest  investment  attributes are  designated  Aa1, A1, Baa1, Ba1 and B1
respectively.

      In addition to the alphabetic  rating system  described  above,  Municipal
Bonds rated by Moody's which have a demand feature that provides the holder with
the ability to  periodically  tender  ("put") the portion of the debt covered by
the demand  feature,  may also have a short-term  rating assigned to such demand
feature.   The   short-term   rating  uses  the  symbol   VMIG  to   distinguish
characteristics  which include  payment upon periodic demand rather than fund or
scheduled maturity dates and potential reliance upon external liquidity, as well
as other  factors.  The highest  investment  quality is designated by the VMIG 1
rating and the lowest by VMIG 4.

      |X|  Standard  & Poor's  Corporation.  The  ratings  of  Standard & Poor's
Corporation  ("S&P") for Municipal  Bonds are AAA (Prime),  AA (High  Grade),  A
(Good Grade),  BBB (Medium  Grade),  BB, B, CCC, CC, and C (speculative  grade).
Bonds rated in the top four categories  (AAA, AA, A, BBB) are commonly  referred
to as "investment  grade."  Municipal  Bonds rated AAA are  "obligations  of the
highest   quality."  The  rating  of  AA  is  accorded  issues  with  investment
characteristics  "only  slightly  less  marked  than those of the prime  quality
issues." The rating of A describes "the third strongest  capacity for payment of
debt  service."  Principal  and interest  payments on bonds in this category are
regarded as safe. It differs from the two higher ratings  because,  with respect
to  general  obligations  bonds,  there is some  weakness,  either  in the local
economic base, in debt burden, in the balance between revenues and expenditures,
or in quality of management.  Under certain adverse circumstances,  any one such
weakness might impair the ability of the issuer to meet debt obligations at some
future date. With respect to revenue bonds , debt service  coverage is good, but
not  exceptional.  Stability of the pledged  revenues could show some variations
because of increased  competition  or economic  influences  on  revenues.  Basic
security  provisions,  while  satisfactory,   are  less  stringent.   Management
performance appears adequate.
    


The BBB rating is the lowest  "investment grade" security rating. The difference
between A and BBB  ratings  is that the latter  shows more than one  fundamental
weakness, or one very substantial fundamental weakness, whereas the former shows
only one deficiency among the factors considered. With respect to revenue bonds,
debt  coverage  is only  fair.  Stability  of the  pledged  revenues  could show
variations, with the revenue flow possibly being subject to erosion over time.
 Basic security provisions are no more
   
than adequate.  Management performance could be stronger.  Bonds rated "BB" have
less near-term  vulnerability to default than other speculative issues. However,
it faces major ongoing uncertainties or exposure to adverse business, financial,
or economic  conditions  which would lead to inadequate  capacity to meet timely
interest and principal payments. Bonds rated "B" have a greater vulnerability to
default,  but currently has the capacity to meet interest payments and principal
repayments.  Adverse  business,  financial,  or economic  conditions will likely
impair capacity or willingness to pay interest and repay principal.  Bonds rated
"CCC" have a current  identifiable  vulnerability  to default,  and is dependent
upon  favorable  business,  financial,  and economic  conditions  to meet timely
payment  of  interest  and  repayment  of  principal.  In the  event of  adverse
business,  financial,  or  economic  conditions,  it is not  likely  to have the
capacity to pay interest and repay  principal.  Bonds noted "CC"  typically  are
debt  subordinated  to senior debt which is assigned on actual or implied  "CCC"
debt rating.

      Bonds rated "C"  typically are debt  subordinated  to senior debt which is
assigned an actual or implied "CCC-" debt rating.  The "C" rating may be used to
cover a situation where a bankruptcy  petition has been filed,  but debt service
payments are continued.  Bonds rated "D" are in payment default.  The "D" rating
category is used when  interest  payments or principal  payments are not made on
the date due even if the  applicable  grace period has not  expired,  unless S&P
believes that such payments will be made during the grace period. The "D" rating
also  will be used upon the  filing of a  bankruptcy  petition  if debt  service
payments  are  jeopardized.  The  ratings  from AA to CCC may be modified by the
addition  of a plus or minus  sign to show  relative  standing  within the major
rating categories.

      |X| Fitch.  The ratings of Fitch  Investors  Service,  Inc. for  Municipal
Bonds are AAA, AA, A, BBB, BB, B, CCC,  CC, C, DDD, DD, and D.  Municipal  Bonds
rated AAA are judged to be of the "highest credit  quality." The rating of AA is
assigned to bonds of "very high credit quality." Municipal Bonds which are rated
A by Fitch are  considered to be of "high credit  quality." The rating of BBB is
assigned to bonds of  "satisfactory  credit  quality." The A and BBB rated bonds
are more  vulnerable to adverse  changes in economic  conditions than bonds with
higher  ratings.  Bonds  rated  AAA,  AA,  A and  BBB  are  considered  to be of
investment  grade  quality.  Bonds  rated  below  BBB  are  considered  to be of
speculative  quality.  The ratings of "BB" is assigned  to bonds  considered  by
Fitch to be "speculative."  The rating of "B" is assigned to bonds considered by
Fitch to be "highly  speculative."  Bonds rated "CCC" have certain  identifiable
characteristics  which, if not remedied,  may lead to default.  Bonds rated "CC"
are minimally  protected.  Default in payment of interest and/or principal seems
probable  over  time.  Bonds  rated "C" are in  imminent  default  in payment of
interest  or  principal.  Bonds  rated  "DDD",  "DD" and "D" are in  default  on
interest and/or  principal  payments.  DDD represents the highest  potential for
recovery on these bonds, and D represents the lowest potential for recovery.

     o Duff & Phelps. The ratings of Duff & Phelps are as follows: AAA which are
judged to be the "highest  credit  quality".  The risk  factors are  negligible,
being only slightly more than for risk-free US Treasury debt. AA+, AA & AA- High
credit  quality  protection  factors  are  strong.  Risk is modest  but may vary
slightly from time to time because of economic conditions.  A+, A & A-Protection
factors are average but  adequate.  However,  risk factors are more variable and
greater in periods of economic stress. BBB+, BBB & BBB- Below average protection
factors but still  considered  sufficient for prudent  investment.  Considerable
variability in risk during economic cycles. BB+, BB & BB- Below investment grade
but  deemed to meet  obligations  when due.  Present  or  prospective  financial
protection  factors  fluctuate  according  to  industry  conditions  or  company
fortunes.  Overall quality may move up or down  frequently  within the category.
B+, B & B- Below  investment grade and possessing risk that obligations will not
be met when due. Financial protection factors will fluctuate widely according to
economic cycles,  industry conditions and/or company fortunes.  Potential exists
for  frequent  changes in the rating  within  this  category or into a higher of
lower rating grade.  CCC Well below investment  grade  securities.  Considerable
uncertainty  exists as to timely  payment of  principal  interest  or  preferred
dividends.  Protection  factors  are  narrow  and risk can be  substantial  with
unfavorable  economic  industry  conditions,  and/or  with  unfavorable  company
developments.  DD Defaulted  debt  obligations  issuer failed to meet  scheduled
principal and/or interest payments. DP Preferred stock with dividend averages.

Municipal Notes

      |X| Moody's  ratings for state and  municipal  notes and other  short-term
loans are  designated  Moody's  Investment  Grade  ("MIG").  Notes  bearing  the
designation  MIG-1 are of the best  quality,  enjoying  strong  protection  from
established  cash flows of funds for their  servicing  or from  established  and
broad-based  access to the market for financing.  Notes bearing the  designation
"MIG-2" are of high quality with ample  margins of  protection,  although not as
large as notes rated "MIG ." Such  short-term  notes which have demand  features
may also  carry a rating  using the symbol  VMIG as  described  above,  with the
designation  MIG-1/VMIG 1 denoting best quality, with superior liquidity support
in addition to those characteristics attributable to the designation MIG-1.

      |X| S&P's rating for Municipal  Notes due in three years or less are SP-1,
SP-2,  and SP-3.  SP-1  describes  issues  with a very  strong  capacity  to pay
principal  and interest and compares with bonds rated A by S&P; if modified by a
plus sign, it compares with bonds rated
"SP2" AA or AAA by S&P.  SP-2
describes issues with a satisfactory capacity to pay principal and interest, and
compares  with  bonds  rated  BBB by S&P.  SP-3  describes  issues  that  have a
speculative capacity to pay principal and interest.

      |X|  Fitch's  rating for  Municipal  Notes due in three  years or less are
F-1+,  F-1,  F-2,  F-3, F-S and D. F-1+  describes  notes with an  exceptionally
strong credit quality and the strongest  degree of assurance for timely payment.
F-1 describes  notes with a very strong  credit  quality and assurance of timely
payment is only  slightly  less in degree than issues rated F-1+.  F-2 describes
notes with a good credit quality and a satisfactory assurance of timely payment,
but the  margin  of  safety  is not as great  for  issues  assigned  F-1+ or F-1
ratings.  F-3  describes  notes  with  a fair  credit  quality  and an  adequate
assurance of timely  payment,  but  near-term  adverse  changes could cause such
securities to be rated below  investment  grade.  F-S describes  notes with weak
credit quality. Issues rated D are in actual or imminent payment default.

Corporate Debt

      The "other  debt  securities"  included  in the  definition  of  temporary
investments  are  corporate  (as opposed to  municipal)  debt  obligations.  The
Moody's,  S&P and Fitch  corporate  debt ratings shown do not differ  materially
from those set forth above for Municipal Bonds.

Commercial Paper

      |X|  Moody's  The  ratings of  commercial  paper by Moody's  are  Prime-1,
Prime-2,  Prime-3 and Not Prime.  Issuers rated Prime-1 have a superior capacity
for repayment of short-term promissory obligations. Issuers rated Prime-2 have a
strong  capacity for repayment of  short-term  promissory  obligations.  Issuers
rated Prime-3 have an acceptable capacity for repayment of short-term promissory
obligations.  Issuers rated Not Prime do not fall within any of the Prime rating
categories.

     |X| S&P The ratings of commercial paper by S&P are A-1, A-2, A-3, B, C, and
D. A-1 indicates that the degree of safety  regarding  timely payment is strong.
A-2 indicates capacity for timely payment is satisfactory. However, the relative
degree of safety is not as high as for issues  designated  A-1. A-3 indicates an
adequate capacity for timely payments. They are, however, more vulnerable to the
adverse effects of changes in circumstances than obligations carrying the higher
designations.  B indicates  only  speculative  capacity  for timely  payment.  C
indicates a doubtful capacity for payment. D is assigned to issues in default.

      |X| Fitch The  ratings  of  commercial  paper by Fitch are  similar to its
ratings of Municipal Notes, above.

                       TAX-EQUIVALENT YIELDS


   
The equivalent  yield tables below compare  tax-free  income with taxable income
under Federal income tax rates effective January 1, 1997. The tables assume that
an  investor's  highest  tax  bracket  applies to the  change in taxable  income
resulting from a switch between  taxable and non-taxable  investments,  that the
investor is not subject to the  Alternative  Minimum  Tax, and that state income
tax payments are fully  deductible for Federal  income tax purposes.  The income
tax brackets  are subject to indexing in future years to reflect  changes in the
Consumer Price Index.
    

Example:  Assuming a 4.0% tax-free  yield,  the equivalent  taxable
yield would be 6.25% for a person in the 36% tax bracket.

Oppenheimer  Insured  Municipal  Fund  is a  mutual  fund  with  the  investment

Expenses

   
The Fund pays a variety of  expenses  directly  for  management  of its  assets,
administration,  distribution  of its  shares  and  other  services,  and  those
expenses are subtracted from the Fund's assets to calculate the Fund's net asset
value per share.  All  shareholders  therefore  pay those  expenses  indirectly.
Shareholders  pay other  expenses  directly,  such as sales  charges and account
transaction  charges.  The following  tables are provided to help you understand
your  direct  expenses  of  investing  in the Fund and your  share of the Fund's
operating expenses that you will bear indirectly. The numbers below are based on
the Fund's expenses during its last fiscal year ended September 30, 1997.
    

      o  Shareholder  Transaction  Expenses  are charges you pay when you buy or
sell shares of the Fund. Please refer to "About Your Account,"  starting on page
__, for an explanation of how and when these charges apply.

1. If you  invest $1  million  or more in Class A shares,  you may have to pay a
sales charge of up to 1% if you sell your shares  within 12 calendar  months (18
months for shares  purchased  prior to May 1, 1997) from the end of the calendar
month in which you purchased those shares. See "How to Buy Shares - Buying Class
A Shares," below.
    

2. See "How to Buy  Shares - Buying  Class B  Shares"  and "How to Buy  Shares -
Buying Class C Shares," below, for more information on the
contingent deferred sales charge.

   
3. There is a $10 transaction  fee for  redemptions  paid by Federal Funds wire,
but not for redemptions paid by check or by ACH wire through AccountLink, or for
which checkwriting privileges are used
    
(see "How To Sell Shares").

   
      o Annual Fund  Operating  Expenses  are paid out of the Fund's  assets and
represent the Fund's expenses in operating its business.  For example,  the Fund
pays management fees to its investment advisor, OppenheimerFunds, Inc. (referred
to in this Prospectus as the "Manager"). The rates of the Manager's fees are set
forth in "How the Fund is Managed,"  below.  The Fund has other regular expenses
for services,  such as transfer agent fees, custodial fees paid to the bank that
holds the Fund's  portfolio  securities,  audit fees and legal  expenses.  Those
expenses are detailed in the Fund's  Financial  Statements  in the  Statement of
Additional Information.

  Expenses

   
      The numbers in the chart  above are based upon the Fund's  expenses in its
last  fiscal  year  ended  September  30,  1997.  These  amounts  are shown as a
percentage of the average net assets of each class of the Fund's shares for that
year. The 12b-1 Plan Fees for Class A shares are Service Plan Fees . For Class B
and Class C shares the 12b-1  Plan Fees are  Service  Plan Fees and  asset-based
sales  charges.  The  service  fee for each  class is a maximum  of 0.25% of the
average annual net assets of the class and the asset-based  sales charge s B and
Class C shares is 0.75%.  These plans are described in greater detail in "How to
Buy Shares," below.

      The actual  expenses  for each class of shares in future years may be more
or less  than the  numbers  in the  chart,  depending  on a number  of  factors,
including  changes in the actual value of the Fund's assets  represented by each
class of shares.

      o Examples.  To try to show the effect of these  expenses on an investment
over time, we have created the  hypothetical  examples shown below.  Assume that
you make a $1,000  investment in each class of shares of the Fund,  and that the
Fund's annual  return is 5%, and that its operating  expenses for each class are
the ones shown in the Annual Fund Operating Expenses table above. If you were to
redeem your shares at the end of each period shown below,  your investment would
incur the following expenses by the end of 1, 3, 5 and 10 years:
    

                     1 year    3 years      5 years     10 years(1)
- -------------------------------------------------------------------
   
Class A Shares       $57       $76          $ 98        $159
    
- -------------------------------------------------------------------
   
Class B Shares       $67       $84          $113        $163
    
- -------------------------------------------------------------------
   
Class C Shares       $27       $54          $ 93        $203
    

      If you did not  redeem  your  investment,  it would  incur  the  following
expenses:

                     1 year    3 years      5 years     10 years(1)
- -------------------------------------------------------------------
   
Class A Shares       $57       $76          $98         $159
    
- -------------------------------------------------------------------
   
Class B Shares       $17       $54          $93         $163
    
- -------------------------------------------------------------------
   
Class C Shares       $17       $54          $93         $203

1. In the first example,  expenses  include the Class A initial sales charge and
the  applicable  Class B or Class C contingent  deferred  sales  charge.  In the
second example,  Class A expenses include the initial sales charge,  but Class B
and Class C expenses do not include contingent deferred sales charges. The Class
B expenses in years 7 through 10 are based on the Class A expenses  shown above,
because the Fund automatically  converts your Class B shares into Class A shares
after 6 years.  Because of the effect of the  asset-based  sales  charge and the
contingent  deferred  sales  charge  imposed  on  Class B and  Class  C  shares,
long-term  holders  of  Class  B and  Class C  shares  could  pay  the  economic
equivalent  of more  than the  maximum  front-end  sales  charge  allowed  under
applicable  regulations.  For Class B shareholders,  the automatic conversion of
Class B shares to Class A Shares is  designed to minimize  the  likelihood  that
this will occur. Please refer to "How to Buy Shares - Buying Class B Shares" for
more information.
    

      These examples show the effect of expenses on an  investment,  but are not
meant to state or predict actual or expected costs or investment  returns of the
Fund, all of which may be more or less than those shown below.


A Brief Overview of the Fund

Some of the important facts about the Fund are summarized below, with references
to the section of this Prospectus where more complete  information can be found.
You should carefully read the entire  Prospectus  before making a decision about
investing  in the Fund.  Keep the  Prospectus  for  reference  after you invest,
particularly for information about your account, such as how to sell or exchange
shares.

     o What Is The Fund's Investment Objective?  The Fund's investment objective
is to seek a high level of current income exempt from Federal income tax.

     o What Does the Fund Invest In? To seek its objective, the Fund will, under
normal  market  conditions,  invest  at least  80% of its  assets  in  Municipal
Securities  and will  invest at least 65% of its  assets  in  insured  Municipal
Securities.  Pre-refunded  Municipal Securities will be considered to be insured
for this purpose.  Pre- refunded Municipal Securities generally are rated in the
highest   rating   category  by  the  various   nationally   recognized   rating
organizations  because of U.S. government agency collateral set aside to support
debt service  payments on the bonds.  The Fund may also use hedging  instruments
and  some  derivative  investments  to try to  manage  investment  risks.  These
investments  and their risks are more fully  explained in "Investment  Objective
and Policies," starting on page __.

   
      o Who Manages the Fund? The Fund's investment advisor is OppenheimerFunds,
Inc., which  (including  subsidiaries)  manages  investment  company  portfolios
having over $75 billion in assets at December 31,  1997.  The Manager is paid an
advisory fee by the Fund, based on its assets. The Fund's portfolio manager, who
is employed by the Manager and who is primarily responsible for the selection of
the Fund's securities, is Caryn Halbrecht. The Fund's Board of Trustees, elected
by  shareholders,  oversees the  investment  advisor and the portfolio  manager.
Please  refer  to  "How  the  Fund is  Managed,"  starting  on page __ for  more
information about the Manager and its fees.

      o How Risky is the Fund? All investments  carry risks to some degree.  The
risk of loss from issuer default is  substantially  reduced by the Fund's policy
of investing in insured Municipal Securities. However, the Fund's investments in
municipal  bonds are  subject to changes in their value from a number of factors
such as  changes  in  general  bond  market  movements,  the  change in value of
particular  securities  because of an event affecting the issuer,  or changes in
interest rates. These changes affect the value of the Fund's investments and its
price per share. In the OppenheimerFunds spectrum, the Fund is more conservative
than high yield bond funds,  but more risky than money market  funds.  While the
Manager  tries  to  reduce  risks  by  diversifying  investments,  by  carefully
researching securities before they are purchased for the portfolio,  by focusing
on insured municipal bonds, and in some cases by using hedging techniques, there
is no guarantee of success in achieving the Fund's objective and your shares may
be worth more or less than their  original  cost when you  redeem  them.  Please
refer to "Investment  Risks" starting on page __ for a more complete  discussion
of the Fund's investment risks.

      o How  Can I Buy  Shares?  You can  buy  shares  through  your  dealer  or
financial  institution,  or you can purchase shares directly  through the Fund's
Distributor  by completing an  Application  or by using an Automatic  Investment
Plan under AccountLink.  Please refer to "How To Buy Shares" starting on page __
for more details.

      o Will I Pay a Sales Charge to Buy Shares?  The Fund has three  classes of
shares.  All three  classes have the same  investment  portfolio  but  different
expenses.  Class A shares are offered with a front-end sales charge, starting at
4.75%, and reduced for larger  purchases.  Class B shares and Class C shares are
offered  without a front-end  sales  charge,  but may be subject to a contingent
deferred  sales  charge if redeemed  within five years or 12 months of purchase,
respectively.  There is also an annual  asset-based  sales charge on Class B and
Class C shares.  Please review "How To Buy Shares"  starting on page __ for more
details,  including a discussion  about factors you and your  financial  advisor
should consider in determining which class may be appropriate for you.

      o How Can I Sell My Shares? Shares can be redeemed by mail or by telephone
call to the Transfer  Agent on any business  day, or through your dealer,  or by
writing a check against your Fund account  (available  for Class A shares only).
Please refer to "How To Sell  Shares" on page __. The Fund also offers  exchange
privileges  to the  other  Oppenheimer  funds,  described  in "How  to  Exchange
Shares," on page __.

      o How Has the Fund Performed? The Fund measures its performance by quoting
its yield,  tax  equivalent  yield,  average  annual total return and cumulative
total return, which measure historical performance. Those yields and returns can
be compared to the yields and returns (over similar  periods) of other funds. Of
course, other funds may have different  objectives,  investments,  and levels of
risk. The Fund's performance can also be compared to a broad market index, which
we have done on pages __ and __. Please remember that past  performance does not
guarantee future results.

sales of investment securities (excluding short-term  securities) for the period
ended September 30, 1997 were $93,793,427 and $80,614,521, respectively.

Investment Objective and Policies

     Objective.  The Fund's  investment  objective is to provide a high level of
current income exempt from Federal income tax.

Investment Policies and Strategies.  The Fund will seek to attain its investment
objective by  investing,  under normal  market  conditions,  at least 80% of its
assets in  Municipal  Securities  and will  invest at least 65% of its assets in
insured  Municipal  Securities.   Pre-refunded   Municipal  Securities  will  be
considered to be insured for this  purpose.  Pre-refunded  Municipal  Securities
generally  are rated in the highest  rating  category by the various  nationally
recognized rating organizations because of U.S. government agency collateral set
aside to support debt service payments on the bonds.

      The Fund will not invest more than 10% of its total  assets in  securities
which are not  investment  grade (or if not  rated,  of  comparable  quality  as
determined by the Manager). Investment grade securities are those rated - or are
determined  by the Manager to be of  comparable  quality to those rated - within
the four highest rating categories of Moody's Investors Service,  Inc., Standard
&  Poor's   Corporation,   Fitch  Investors   Service,   Inc.  or  other  rating
organization.

      Under  normal  market  conditions,  no more than 20% of the  Fund's  total
assets will be invested in taxable investments. However, for temporary defensive
purposes,  the Fund may  invest up to 100% of its  invested  assets  in  taxable
certificates  of deposit and  commercial  paper and taxable or tax-exempt  money
market   instruments.   The  Fund  may  purchase   Municipal   Securities  on  a
"when-issued" basis and may purchase or sell Municipal  Securities on a "delayed
delivery" basis.

     o Can the Fund's Investment  Objective and Policies Change? The Fund has an
investment objective, described above, as well as investment policies it follows
to try to achieve its objective.  Additionally, the Fund uses certain investment
techniques and strategies in carrying out those investment policies.  The Fund's
investment policies and techniques are not "fundamental"  unless this Prospectus
or the  Statement of  Additional  Information  says that a particular  policy is
"fundamental." The Fund's investment objective is a fundamental policy.

      Fundamental policies are those that cannot be changed without the approval
of a "majority" of the Fund's  outstanding voting shares. The term "majority" is
defined  in  the  Investment  Company  Act  to  be a  particular  percentage  of
outstanding  voting  shares  (and this term is  explained  in the  Statement  of
Additional Information). The Fund's Board of Trustees may change non-fundamental
policies without  shareholder  approval,  although  significant  changes will be
described in amendments to this Prospectus.

   
      o Portfolio Turnover. A change in the securities held by the Fund is known
as "portfolio  turnover."  The Fund  generally will not engage in the trading of
securities for the purpose of realizing  short-term gains, but the Fund may sell
securities as the Manager deems advisable to take advantage of  differentials in
yield to seek to accomplish the Fund's  investment  objective.  While short-term
trading  increases  portfolio  turnover and may increase the Fund's  transaction
costs, the Fund incurs little or no brokerage The "Financial Highlights," above,
shows the Fund's portfolio turnover rate during past fiscal years.
    

Investment Risks

      All  investments  carry risks to some degree,  whether they are risks that
market prices of the investment  will fluctuate (this is known as "market risk")
or that the underlying  issuer will experience  financial  difficulties  and may
default on its obligation  under a  fixed-income  investment to pay interest and
repay principal (this is referred to as "credit risk"). These general investment
risks,  and the special risks of certain types of investments  that the Fund may
hold are described below. They affect the value of the Fund's  investments,  its
investment  performance,  and the prices of its shares. These risks collectively
form the risk profile of the Fund.

      Because of the types of securities  the Fund invests in and the investment
techniques  the Fund uses,  the Fund is designed for investors who are investing
for the long term.  It is not intended for  investors  seeking  assured  income.
While  the  Manager  tries to  reduce  risks  by  diversifying  investments,  by
carefully researching securities before they are purchased, and in some cases by
using  hedging  techniques,  changes in overall  market  prices can occur at any
time, and because the income earned on securities is subject to change, there is
no  assurance  that the Fund will  achieve its  investment  objective.  When you
redeem your shares, they may be worth more or less than what you paid for them.

      o Interest Rate Risk.  The values of Municipal  Securities  will vary as a
result of changing  evaluations by rating  services and investors of the ability
of the issuers of such securities to meet their principal and interest payments.
Such values will also  change in response to changes in interest  rates:  should
interest  rates  rise,  the  values of  outstanding  Municipal  Securities  will
probably  decline  and  (if  purchased  at  principal  amount)  would  sell at a
discount;  should  interest  rates  fall,  the values of  outstanding  Municipal
Securities will probably  increase and (if purchased at principal  amount) would
sell at a premium.  Changes  in the value of  Municipal  Securities  held in the
Fund's  portfolio  arising from these or other factors will not affect  interest
income derived from those  securities but will affect the Fund's net asset value
per share.  Insurance on the  Municipal  Securities  of the Fund does not insure
against  fluctuations  in the net asset value of the Fund's shares,  and the net
asset value will be affected by increases or  decreases in  prevailing  interest
rates.

      Generally,  securities of longer  maturities  are subject to greater price
fluctuations due to changes in interest rates.  There are no restrictions on the
maturities  of the Municipal  Securities in which the Fund may invest.  The Fund
will  seek to  invest in  Municipal  Securities  that,  in the  judgment  of the
Manager,  will provide a high level of current income consistent with the Fund's
liquidity requirements, conditions affecting the Municipal Securities market and
the cost of the insurance obtainable on such bonds.

   
      o  Insurance.  To the  extent  that  Municipal  Securities  in the  Fund's
portfolio  are  insured,  they  will at all  times  be fully  insured  as to the
scheduled payment of all installments of interest and principal except, as noted
above, for investments made for temporary  liquidity and defensive  purposes and
pending  investment  in  longer  term  Municipal   Securities.   This  insurance
substantially  reduces the risks to the Fund and its shareholders  from defaults
in the portfolio  securities owned by it. The municipal securities in the Fund's
portfolio  that are  covered  by  insurance  will be  covered  by a mutual  fund
"Portfolio  Insurance  Policy" issued by Financial  Guaranty  Insurance  Company
("Financial  Guaranty"),  a "Secondary  Market Insurance Policy" or a "New Issue
Insurance  Policy"  obtained by the issuer or the underwriter of the security at
the time of its original issuance. If a Municipal Security is already covered by
a New Issue Insurance  Policy or Secondary Market  Insurance  Policy,  then such
security is not required to be additionally  insured under a Portfolio Insurance
Policy  issued  by  Financial  Guaranty.  Such New  Issue  Insurance  Policy  or
Secondary Market Insurance Policy may have been issued by Financial  Guaranty or
by other insurers.
    

      Based upon the current  composition of the Fund's  portfolio,  the Manager
estimates  that the  premiums for a Portfolio  Insurance  Policy will range from
0.2% to 0.4% per annum of average  daily net assets.  Premiums are paid from the
Fund's assets,  and will reduce the current yield on its portfolio by the amount
thereof.  When the Fund  purchases  a  Secondary  Market  Insurance  Policy (see
below),  the single premium is added to the cost basis of the Municipal Security
and is not considered an item of expense for the Fund.

      Any of the policies  discussed  above insure the scheduled  payment of all
principal  and  interest  on the  Municipal  Securities  as they fall  due.  The
insurance does not guarantee the market value of the Municipal Securities or the
value of the shares of the Fund and, except as described below, has no effect on
the net asset value or redemption price of the shares of the Fund. The insurance
of  principal  refers  to the  face or par  value  of the  security,  and is not
affected  by the price paid  therefor by the Fund or the market  value  thereof.
Payment  of a claim  under an  insurance  policy  depends  on the  claims-paying
ability  of the  insurer  and no  representation  is made by the  Fund as to the
ability of any insurer to meet its commitments.

   
      The New Issue Insurance  Policies,  if any, on the Fund's  securities have
been obtained by the respective issuers or underwriters of those securities, and
all premiums with respect to such  securities  have been paid in advance by such
issuers or underwriters.  Such policies are  non-cancelable and will continue in
force so long as the securities  are  outstanding  and the  respective  insurers
remain in business.  Since New Issue Insurance  remains in effect as long as the
securities insured thereby are outstanding,  the insurance may have an effect on
the resale value of securities  in the Fund's  portfolio.  Therefore,  New Issue
Insurance may be considered to represent an element of market value in regard to
securities thus insured, but the exact effect, if any, of this insurance on such
market value cannot be  estimated.  The Fund will acquire  Municipal  Securities
subject to New Issue Insurance Policies only if the claims-paying ability of the
insurer  thereof is rated  "AAA" by S&P, or has a similar  rating  from  another
rating organization at the date of purchase.
    

      The  Portfolio  Insurance  Policy  obtained  by the  Fund  from  Financial
Guaranty will be effective  only so long as the Fund is in existence,  Financial
Guaranty is in business,  and the Municipal  Securities  described in the policy
continue  to be held  by the  Fund.  In the  event  of a sale  of any  Municipal
Security by the Fund or payment thereof prior to maturity because such Municipal
Security is called or redeemed,  the Portfolio Insurance Policy terminates as to
such security.

      The Portfolio  Insurance  Policy  obtained by the Fund is  non-cancellable
except for failure to pay the premium.  Nonpayment  of premiums on the Portfolio
Insurance Policy obtained by the Fund will, under certain circumstances,  result
in the  cancellation  of the  Portfolio  Insurance  Policy and also will  permit
Financial  Guaranty to take action against the Fund to recover premium  payments
due it. The premium rate for each security  covered by the  Portfolio  Insurance
Policy is fixed for the life of the Fund at the time of purchase.  The insurance
premiums are payable  monthly by the Fund and are adjusted for purchases,  sales
and payments prior to maturity of covered securities during the month. Financial
Guaranty  cannot  cancel  coverage  already in force with  respect to  Municipal
Securities  owned by the Fund and  covered  by the  Portfolio  Insurance  Policy
except for non-payment of premiums. If any insurance for a Municipal Security is
canceled,  the Manager will determine as promptly thereafter as possible whether
that security should be sold by the Fund.

      In  determining  whether  to  insure  any  Municipal  Security,  Financial
Guaranty  applies its own standards,  which are not  necessarily the same as the
criteria  used in regard to the  selection of  securities  by the Manager.  That
decision is made prior to the Fund's purchase of such  securities.  Contracts to
purchase  securities are not covered by the Portfolio  Insurance Policy although
securities underlying such contracts are covered by such insurance upon physical
delivery of the securities to the Fund or the Fund's Custodian.

      o  Secondary  Market  Insurance.  The Fund may at any time  purchase  from
Financial Guaranty a Secondary Market Insurance Policy on any Municipal Security
purchased by the Fund that is covered by a Portfolio Insurance Policy. The right
of the Fund to obtain a Secondary  Market  Insurance  Policy  with  respect to a
security is in addition to the Portfolio Insurance Policy. However, the coverage
and obligation to pay monthly  premiums under a Portfolio  Insurance Policy with
respect to a security  would cease with the  purchase by the Fund of a Secondary
Market Insurance Policy on such security.

      By purchasing a Secondary Market Insurance  Policy,  the Fund would,  upon
payment of a single pre-determined premium, obtain insurance against non-payment
of scheduled  principal  and interest for the  remaining  term of the  security,
regardless of whether the Fund then owned the security.  Such insurance coverage
will be  noncancelable  and will  continue  in force so long as the  security so
insured is  outstanding.  The  purpose of  acquiring  such a policy  would be to
enable  the Fund to sell the  Municipal  Security  to a third  party as an "AAA"
rated  insured  security at a market price higher than what  otherwise  might be
obtainable if the security were sold without the insurance coverage. Such rating
is not automatic,  however, and must specifically be requested from S&P for each
security.  Such  policy  likely  would be  purchased  if, in the  opinion of the
Manager,  the market  value or net proceeds of a sale of the security so insured
would exceed the current value of the security (without insurance) plus the cost
of the policy.  Any  difference  between a  security's  market value as an "AAA"
rated  security and its market value  without such rating,  including the single
premium cost  thereof,  would inure to the Fund in  determining  the net capital
gain or loss realized by the Fund upon the sale of the portfolio  security.  The
Fund may purchase insurance under a Secondary Market Insurance Policy in lieu of
a Portfolio  Insurance  Policy at any time,  regardless  of the effect on market
value  of the  underlying  Municipal  Security,  if the  Manager  believes  such
insurance  would best serve the Fund's  interests in meeting its  objectives and
policies.  The Secondary  Market  Insurance Policy allows the Fund to purchase a
Secondary Market Insurance Policy on a security which is currently in default as
to payments by the issuer and to sell such  security on an insured  basis rather
than be obligated to hold the  defaulted  security in its  portfolio in order to
continue in force the applicable Portfolio Insurance Policy.

      o Financial Guaranty  Insurance Company.  Financial Guaranty is a New York
stock insurance company,  with principal offices at 115 Broadway,  New York, New
York, 10006.  "Investment Objective and Policies" in the Statement of Additional
Information contains more information on Financial Guaranty.

   
      o There are special  risks in investing  in  derivative  investments.  The
risks of investing in derivative investments include not only the ability of the
issuer of the derivative investment to pay the amount due on the maturity of the
investment,  but also the risk that the  underlying  security or  investment  on
which the derivative is based and the derivative itself, may not perform the way
the Manager  expected it to  perform.  That can mean that the Fund will  realize
less income than  expected or that it can lose part of its  investment.  Another
risk of investing in derivative  investments is that their market value could be
expected to vary to a much  greater  extent than the market  value of  municipal
securities that are not derivative  investments but have similar credit quality,
redemption provisions and maturities. These risks affect the price of the Fund's
shares.
    

      o Hedging instruments can be volatile  investments and may involve special
risks.  If the  Manager  uses a hedging  instrument  at the wrong time or judges
market conditions incorrectly,  hedging strategies may reduce the Fund's return.
The Fund could also  experience  losses if the prices of its futures and options
positions  were not  correlated  with its other  investments  or if it could not
close out a position because of an illiquid market for the future or option.

      Options  trading  involves  the  payment of  premiums  and has special tax
effects  on the  Fund.  There  are  also  special  risks in  particular  hedging
strategies.  For example,  in writing puts, there is a risk that the Fund may be
required to buy the underlying security at a disadvantageous  price. These risks
and the hedging  strategies  the Fund may use are described in greater detail in
the Statement of Additional Information.

Investment  Techniques  and  Strategies.  The Fund  may also use the  investment
techniques and strategies  described  below.  These  techniques  involve certain
risks. The Statement of Additional  Information  contains more information about
these practices,  including limitations on their use that are designed to reduce
some of the risks.

   
      o  Municipal  Securities.  "Municipal  Securities"  are  municipal  bonds,
municipal  notes, tax  anticipation  notes,  bond  anticipation  notes,  revenue
anticipation  notes,   construction  loan  notes  and  other  short-term  loans,
tax-exempt commercial paper and other debt obligations issued by or on behalf of
states, the District of Columbia, any commonwealths,  territories or possessions
of the United States,  or their  respective  political  subdivisions,  agencies,
instrumentalities  or  authorities,  the  interest  from which is not subject to
Federal  individual  income tax in the opinion of bond counsel to the respective
issuer at the time of issue. No independent  investigation is or will be made by
the Manager as to the users of proceeds of bond offerings or the  application of
such proceeds.
    

      The two principal  classifications  of Municipal  Securities  are "general
obligations"  (secured  by the  issuer's  pledge of its full  faith,  credit and
taxing  power  for  the  payment  of  principal   and   interest)  and  "revenue
obligations"  (payable only from the revenues derived from a particular facility
or class of facilities or a specific  excise tax or other revenue  source).  The
Fund may invest in  Municipal  Securities  of both  classifications,  subject to
particular restrictions described below.

      Yields on  Municipal  Securities  vary  depending on a variety of factors,
including the general  condition of the  financial  markets and of the Municipal
Securities market in particular, the size of a particular offering, the maturity
of the  security  and the  credit  rating of the  issuer.  Generally,  Municipal
Securities of longer maturities produce higher current yields but are subject to
greater price  fluctuation due to changes in interest rates  (discussed  above),
tax laws and other general  market  factors than are Municipal  Securities  with
shorter  maturities.  Similarly,  lower- rated  Municipal  Securities  generally
produce a greater yield than higher-rated  Municipal Securities due to a concern
that there is a greater  degree of risk as to the  ability of the issuer to meet
principal and interest  obligations.  "Investment Objective and Policies" in the
Statement of Additional  Information  contains more information  about Municipal
Securities.

   
      o Investments  in Taxable  Securities and Temporary  Defensive  Investment
Strategy.  Under normal market conditions,  the Fund may invest up to 20% of its
assets in taxable  investments,  including (i) certain  "Temporary  Investments"
(described  immediately below); (ii) hedging instruments (described in "Hedging"
below); (iii) repurchase agreements (explained below).

      In times of  unstable  economic  or market  conditions,  the  Manager  may
determine that it is appropriate for the Fund to assume a temporary  "defensive"
position  by  investing  some or all of its  assets  (there  is no  limit on the
amount) in short-term  money market  instruments.  These  Temporary  Investments
include the taxable  investments  described above, U.S.  government  securities,
bank obligations,  commercial paper, corporate obligations and other instruments
approved by the Fund's Board of Trustees.  This strategy would be implemented to
attempt to reduce  fluctuations in the value of the Fund's assets.  The Fund may
hold Temporary  Investments  pending the investment of proceeds from the sale of
Fund  shares  or  portfolio  securities,  pending  settlement  of  purchases  of
Municipal Securities, or to meet anticipated redemptions. To the extent the Fund
assumes a temporary  defensive position,  a portion of the Fund's  distributions
may be subject to Federal  and state  income  taxes and the Fund may not achieve
its objective.
    

      o Municipal  Lease  Obligations.  The Fund may invest in  certificates  of
participation, which are tax-exempt obligations that evidence the holder's right
to share in lease,  installment  loan or other  financing  payments  by a public
entity.  Projects financed with certificates of participation  generally are not
subject to state constitutional debt limitations or other statutory requirements
that may be applicable to Municipal Securities. Payments by the public entity on
the obligation  underlying the certificates  are derived from available  revenue
sources;  such revenue may be diverted to the funding of other municipal service
projects. Payments of interest and/or principal with respect to the certificates
are not  guaranteed  and do not constitute an obligation of the states or any of
their  political  subdivisions.  While some  municipal  lease  securities may be
deemed to be  "illiquid"  securities  (the purchase of which would be limited as
described below in "Illiquid and Restricted Securities"),  from time to time the
Fund may invest more than 5% of its net assets in  municipal  lease  obligations
that the Manager has determined to be liquid under  guidelines set by the Fund's
Board of  Trustees.  See  "Municipal  Lease  Obligations"  in the  Statement  of
Additional Information for more details.

   
       o  Floating  Rate/Variable  Rate  Obligations.   Some  of  the  Municipal
Securities the Fund may purchase may have variable or floating  interest  rates.
Variable  rates are adjusted at stated  periodic  intervals.  Floating rates are
automatically   adjusted   according  to  a  specified   market  rate  for  such
investments,  such as the  percentage of the prime rate of a bank, or the 90-day
U.S.  Treasury  Bill rate.  Such  obligations  may be secured by bank letters of
credit or other credit support  arrangements.  See "Floating  Rate/Variable Rate
Obligations" in the Statement of Additional Information for more details.

       o Inverse  Floaters and  Derivative  Investments.  The Fund may invest in
variable rate bonds known as "inverse  floaters."  These bonds pay interest at a
rate that varies as the yields  generally  available  on  short-term  tax-exempt
bonds change.  The yields on inverse floaters move in the opposite  direction of
yields on  short-term  bonds in response to market  changes.  When the yields on
short-term tax-exempt bonds go up, the interest rate on the inverse floater goes
down. When the yields on short-term  tax-exempt bonds go down, the interest rate
on the inverse floater goes up. As interest rates rise, inverse floaters produce
less current income. Inverse floaters are a type of "derivative security," which
is  a  specially  designed   investment  whose  performance  is  linked  to  the
performance  of another  security or  investment.  Some inverse  floaters have a
"cap"  whereby  if  interest  rates rise  above the  "cap,"  the  security  pays
additional  interest income. If rates do not rise above the "cap," the Fund will
have paid an additional amount for a feature that proves worthless. The Fund may
also invest in municipal derivative securities that pay interest that depends on
an external  pricing  mechanism.  Examples are  interest  rate swaps or caps and
municipal  bond or swap indices.  The Fund  anticipates  that it would invest no
more than 10% of its total assets in inverse floaters.

      o "When-Issued" and "Delayed Delivery" Transactions. The Fund may purchase
Municipal Securities on a "when-issued" basis and may purchase or sell Municipal
Securities on a "delayed  delivery" basis.  These terms refer to securities that
have been created and for which a market exists, but which are not available for
immediate delivery.  When the Fund engages in these transactions,  it will do so
for the purpose of acquiring  portfolio  securities  consistent  with the Fund's
investment  objective  and  policies  and  not  for the  purpose  of  investment
leverage.  When the Fund is the  buyer,  it will  segregate  with its  custodian
Municipal  Securities  having a total  value  equal to the  amount of the Fund's
purchase commitments until payment is made.
    

      o Repurchase Agreements. The Fund may enter into repurchase agreements. In
a repurchase  transaction,  the Fund buys a security and simultaneously sells it
to the vendor for delivery at a future date.  There is no limit on the amount of
the Fund's net assets that may be subject to repurchase agreements of seven days
or less.  Repurchase  agreements must be fully  collateralized.  However, if the
vendor fails to pay the resale price on the  delivery  date,  the Fund may incur
costs in disposing of the collateral  and may experience  losses if there is any
delay  in its  ability  to do so.  The  Fund  will  not  enter  into  repurchase
transactions  that will  cause  more than 25% of its net assets to be subject to
repurchase  agreements,  and will not enter  into a  repurchase  agreement  that
causes  more than 10% of its net assets to be subject to  repurchase  agreements
having a maturity beyond seven days,  because such repurchase  agreements may be
illiquid (see "Illiquid and Restricted Securities").

   
      o Illiquid and  Restricted  Securities.  Under the policies and procedures
established  by the  Fund's  Board  of  Trustees,  the  Manager  determines  the
liquidity  of certain of the Fund's  investments.  Investments  may be  illiquid
because of the absence of an active trading market, making it difficult to value
them or dispose of them promptly at an acceptable  price. A restricted  security
is one that has a contractual  restriction on its resale or which cannot be sold
publicly until it is registered  under the Securities Act of 1933. The Fund will
not invest more than 10% of its net assets in illiquid or restricted  securities
(the Board may increase that limit to 15%). The Fund's percentage  limitation on
these  investments  does not apply to  certain  restricted  securities  that are
eligible for resale to qualified institutional purchasers.  The Manager monitors
holdings of illiquid securities on an ongoing basis to determine whether to sell
any  holdings  to  maintain  adequate  liquidity.  Illiquid  securities  include
repurchase agreements maturing in more than seven days, or certain participation
interests other than those with puts exercisable within seven days.

      o Loans of Portfolio  Securities.  To attempt to increase its income,  the
Fund may lend its portfolio securities to brokers,  dealers, and other financial
institutions.
    

         If it does the Fund must receive collateral for such loans. These loans
are limited to not more than 5% of the value of the Fund's  total assets and are
subject  to  other   conditions   described  in  the   Statement  of  Additional
Information.  The income from such loans,  when distributed by the Fund, will be
taxable as ordinary income.
    

      o  Puts  and  Stand-By   Commitments.   The  Fund  may  acquire  "stand-by
commitments"  or  "puts"  with  respect  to  municipal  obligations  held in its
portfolio.  Under a stand-by  commitment or put option,  the Fund would have the
right to sell specified  securities at a specific price on demand to the issuing
broker-dealer or bank. The Fund will acquire stand-by commitments or puts solely
to  facilitate  portfolio  liquidity  and does not intend to exercise its rights
thereunder for trading purposes.

      o Hedging.  As  described  below,  the Fund may  purchase and sell certain
kinds of futures contracts, put and call options, forward contracts, and options
on  futures  and  municipal  bond  indices,  or enter  into  interest  rate swap
agreements.  These are referred to as "hedging instruments." The Fund may invest
in financial  futures contracts and related options on those contracts only as a
hedge against anticipated interest rate changes, and the Fund does not intend to
use hedging  instruments for speculative  purposes.  The hedging instruments the
Fund may use are  described  below and in  greater  detail in "Other  Investment
Techniques and Strategies" in the Statement of Additional Information.

      The Fund may buy and sell  options,  futures and forward  contracts  for a
number of  purposes.  It may do so to  establish  a position  in the  securities
market as a temporary substitute for purchasing individual securities.  The Fund
may sell a futures contract or a call option on a futures contract or purchase a
put option on such futures  contract if the Manager  anticipates  that  interest
rates  will  rise,  as a hedge  against a  decrease  in the value of the  Fund's
portfolio  securities.  If the  Manager  anticipates  that  interest  rates will
decline,  the Fund may purchase a futures contract or a call option on a futures
contract,  or sell a put option on a futures  contract,  to  protect  against an
increase in the price of securities the Fund intends to buy.

      Other hedging strategies, such as buying futures and call options, tend to
increase the Fund's  exposure to the  securities  market.  Writing  covered call
options may also provide  income to the Fund for liquidity  purposes or to raise
cash to distribute to
shareholders.

      o Futures.  The Fund may buy and sell  financial  futures  contracts  that
relate to (1) interest  rates (these are referred to as Interest Rate  Futures);
and (2) municipal  bond indices  (these are referred to as Municipal  Bond Index
Futures).  These types of Futures are  described  in "Hedging  With  Options and
Futures  Contracts"  in the Statement of  Additional  Information.  The Fund may
concurrently  buy and sell  Futures  contracts in an attempt to benefit from any
outperformance of the Future purchased relative to the performance of the Future
sold. The Fund may not enter into futures  contracts or purchase related options
on futures contracts,  for other than bona fide hedging purposes, if immediately
after doing so the amount the Fund  committed to initial  margin plus the amount
paid for unexpired  options on futures  contracts exceeds 5% of the Fund's total
assets.

   
      o Put and Call  Options.  The Fund  may buy and sell  exchange-traded  and
over-the-counter  put and call  options,  including  index  options,  securities
options,  and  options on the other  types of futures  described  in  "Futures,"
above. A call or put may be purchased only if, after the purchase,  the value of
all call and put options held by the Fund will not exceed 5% of the Fund's total
assets.
    

      The Fund may buy calls only on debt  securities,  municipal  bond indices,
Municipal  Bond Index  Futures and Interest  Rate  Futures,  or to terminate its
obligation on a call the Fund previously wrote.

   
      If the Fund sells (that is,  writes) a call option,  it must be "covered."
That means the Fund must own the security  subject to the call while the call is
outstanding,  or, for other  types of  written  calls,  the Fund must  segregate
liquid assets to enable it to satisfy its  obligations if the call is exercised.
When the Fund writes a call, it receives cash (called a premium). The call gives
the buyer the ability to buy the  investment  on which the call was written from
the Fund at the call price during the period in which the call may be exercised.
If the value of the investment  does not rise above the call price, it is likely
that the call will lapse without being exercised,  while the Fund keeps the cash
premium  (and the  investment).  Up to 20% of the  Fund's  total  assets  may be
subject to calls.

      The Fund may buy puts whether or not it holds the underlying investment in
the portfolio.
    

          Buying a put on an  investment  gives  the Fund the  right to sell the
investment at a set price to a seller of a put on that  investment.  If the Fund
writes a put, the put must be covered by segregated liquid assets. The Fund will
not write  puts if more than 20% of the  Fund's  total  assets  would have to be
segregated to cover put options.
    

      o Interest  Rate  Swaps.  In an interest  rate swap,  the Fund and another
party exchange  their right to receive or their  obligation to pay interest on a
security.  For example,  they may swap a right to receive floating rate payments
for fixed rate payments.  The Fund enters into swaps only on securities it owns.
The Fund may not enter  into  swaps  with  respect to more than 25% of its total
assets.  Also,  the Fund  will  segregate  liquid  assets  (such as cash or U.S.
Government securities) to cover any amounts it could owe under swaps that exceed
the amounts it is entitled to receive,  and it will adjust that amount daily, as
needed.  The credit risk of an interest rate swap depends on the  counterparty's
ability to perform.

     Other Investment  Restrictions.  The Fund has other investment restrictions
which are  fundamental  policies.  Under these  fundamental  policies,  the Fund
cannot do any of the following:

      o borrow money, except from banks for temporary purposes in amounts not in
excess of 5% of the  value of the  Fund's  assets;  no assets of the Fund may be
pledged, mortgaged or hypothecated other than to secure a borrowing, and then in
amounts not exceeding 10% of the Fund's total assets; borrowings may not be made
for leverage,  but only for liquidity  purposes to satisfy  redemption  requests
when the  liquidation  of portfolio  securities  is considered  inconvenient  or
disadvantageous;  however,  the Fund may  enter  into  when-issued  and  delayed
delivery transactions as described herein;
      o make loans,  except that the Fund may purchase or hold debt obligations,
repurchase  agreements and other  instruments  and securities it is permitted to
own and may lend its portfolio
securities and other investments it owns;
      o buy  securities  issued or guaranteed by any one issuer (except the U.S.
Government or any of its agencies or  instrumentalities)  if with respect to 75%
of its total  assets,  more than 5% of the Fund's total assets would be invested
in  securities  of that  issuer or the Fund would then own more than 10% of that
issuer's voting securities; or
      o invest more than 25% of its total assets in a single industry  (although
the Fund may invest more than 25% of its assets in a  particular  segment of the
municipal  bond market,  it will not invest more than 25% of its total assets in
industrial development bonds in a single industry).

      Unless the prospectus states that a percentage  restriction  applies on an
ongoing basis, it applies only at the time the Fund makes an investment, and the
Fund need not sell securities to meet the percentage  limits if the value of the
investment  increases in  proportion to the size of the Fund.  Other  investment
restrictions  are  listed  in  "Investment  Restrictions"  in the  Statement  of
Additional Information.

How the Fund is Managed

     Organization  and History.  The Fund is one of two  diversified  investment
portfolios or "series" of Oppenheimer Municipal Fund (the "Trust"), an open-end,
management  investment  company  organized as a Massachusetts  business trust in
1986.

   
      The Trust is governed by a Board of Trustees,  which is responsible  under
Massachusetts  law for  protecting the interests of  shareholders.  The Trustees
meet periodically  throughout the year to oversee the Fund's activities,  review
its performance,  and review the actions of the Manager.  "Trustees and Officers
of the Trust" in the Statement of Additional  Information names the Trustees and
officers of the Trust and provides  more  information  about them . Although the
Fund  will not  normally  hold  annual  meetings  of  shareholders,  it may hold
shareholder  meetings from time to time on important  matters,  and shareholders
have the right to call a meeting  to remove a Trustee  or to take  other  action
described in the Declaration of Trust.
    

      The Board of Trustees  has the power,  without  shareholder  approval,  to
divide unissued shares of the Fund into two or more classes.  The Board has done
so, and the Fund  currently  has three  classes of shares,  Class A, Class B and
Class C. All three classes invest in the same investment  portfolio.  Each class
has its own dividends and  distributions  and pays certain expenses which may be
different for the different  classes.  Each class may have a different net asset
value. Each share has one vote at shareholder  meetings,  with fractional shares
voting  proportionally.  Only  shares of a  particular  class vote as a class on
matters that affect that class alone.  Shares are freely  transferrable.  Please
refer to "How the Fund is Managed" in the Statement of Additional Information on
voting of shares.

The  Manager  and  Its   Affiliates.   The  Fund  is  managed  by  the  Manager,
OppenheimerFunds,   Inc.,   which  is  responsible   for  selecting  the  Fund's
investments  and handles its day-to-day  business.  The Manager  carries out its
duties,  subject to the policies established by the Board of Trustees,  under an
Investment Advisory Agreement which states the Manager's  responsibilities.  The
Agreement sets forth the fees paid by the Fund to the Manager, and describes the
expenses that the Fund is responsible to pay to conduct its business.

   
      The Manager has operated as an investment  advisor since 1959. The Manager
(including subsidiaries) currently manages investment companies, including other
Oppenheimer funds, with assets of more than $75 billion as of December 31, 1997,
and held in more than 3.5 million shareholder accounts.  The Manager is owned by
Oppenheimer Acquisition Corp., a holding company that is owned in part by senior
officers of the Manager and  controlled by  Massachusetts  Mutual Life Insurance
Company.

      The  management  services  provided  to the Fund by the  Manager,  and the
services  provided by the  Distributor  and the Transfer Agent to  shareholders,
depend on the  smooth  functioning  of their  computer  systems.  Many  computer
software  systems in use today  cannot  distinguish  the year 2000 from the year
1900 because of the way dates are encoded and  calculated.  That  failure  could
have a negative  impact on  handling  securities  trades,  pricing  and  account
services.  The Manager,  the  Distributor  and Transfer Agent have been actively
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.
    

     o Portfolio Manager.  The portfolio manager of the Fund is Caryn Halbrecht,
a Vice President of the Manager. She has been the person principally responsible
for the day-to-day  management of the Fund's portfolio since October,  1993. Ms.
Halbrecht was previously a Vice President of Fixed Income  Portfolio  Management
at Bankers Trust.

         o Fees and Expenses.  Under the Investment Advisory Agreement, the Fund
pays the Manager the following annual fees:  0.450% of the first $100 million of
average annual net assets,  0.400% of the next $150 million,  0.375% of the next
$250  million,  and 0.350% of net assets in excess of $500  million.  The Fund's
management  fee for its last fiscal year ended  September  30, 1997 was 0.45% of
average annual net assets for its Class A, Class B and Class C shares.
    

      The Fund pays expenses related to its daily operations,  such as custodian
fees, Trustees' fees, transfer agency fees, legal fees and auditing costs. Those
expenses  are  paid  out of the  Fund's  assets  and are not  paid  directly  by
shareholders.  However,  those expenses reduce the net asset value of the Fund's
shares,  and  therefore  are  indirectly  borne by  shareholders  through  their
investment.  More information  about the Investment  Advisory  Agreement and the
other  expenses  paid by the Fund is  contained in the  Statement of  Additional
Information.

   
      There  is  also  information  about  the  Fund's  brokerage  policies  and
practices in  "Brokerage  Policies of the Fund" in the  Statement of  Additional
Information. That section discusses how brokers and dealers are selected for the
Fund's portfolio transactions.  Because the Fund purchases most of its portfolio
securities  directly  from the  sellers and not through  brokers,  it  therefore
incurs relatively little expense for brokerage.  From time to time,  however, it
may use brokers when buying portfolio securities. When deciding which brokers to
use, the Manager is permitted by the Investment  Advisory  Agreement to consider
whether  brokers  have sold  shares of the Fund or any other funds for which the
Manager serves as investment advisor.

      o The  Distributor.  The Fund's shares are sold through  dealers , brokers
and financial  institutions  that have a sales  agreement with  OppenheimerFunds
Distributor,  Inc.,  a  subsidiary  of the  Manager  that  acts  as  the  Fund's
Distributor.  The Distributor also  distributes the shares of other  Oppenheimer
funds and is sub- distributor for funds managed by a subsidiary of the Manager.

      o The  Transfer  Agent.  The  Fund's  transfer  agent is  OppenheimerFunds
Services,  a division of the Manager,  which acts as the  shareholder  servicing
agent  for the  Fund on an  "at-cost"  basis.  It also  acts as the  shareholder
servicing  agent for the other  Oppenheimer  funds.  Shareholders  should direct
inquiries  about  their  accounts  to the  Transfer  Agent  at the  address  and
toll-free number shown below in this Prospectus and on the back cover.
    


Performance of the Fund

   
Explanation of Performance Terminology.  The Fund uses the terms "total return,"
"average annual total return,"  "standardized  yield," "dividend yield," "yield"
and  "tax-equivalent  yield" to illustrate its  performance.  The performance of
each class of shares is shown separately,  because the performance of each class
of shares  will  usually be  different,  as a result of the  different  kinds of
expenses each class bears. These returns and yields measure the performance of a
hypothetical  account  in the Fund  over  various  periods,  and do not show the
performance  of each  shareholder's  account  (which will vary if dividends  are
received in cash, or shares are sold or purchased).  The Fund's  performance may
help you see how well your Fund has done  over time and to  compare  it to other
funds or to a market index.
    

      It is important to  understand  that the Fund's  yields and total  returns
represent  past  performance  and should not be considered to be  predictions of
future returns or performance.  This  performance  data is described  below, but
more detailed  information  about how total returns and yields are calculated is
contained  in the  Statement  of  Additional  Information,  which also  contains
information  about  indices  and other ways to measure  and  compare  the Fund's
performance. The Fund's investment performance will vary over time, depending on
market conditions, the composition of the portfolio, expenses and which class of
shares you purchase.

      o Total  Returns.  There  are  different  types of total  returns  used to
measure  the  Fund's  performance.  Total  return  is the  change  in value of a
hypothetical  investment  in the Fund  over a given  period,  assuming  that all
dividends and capital gains  distributions are reinvested in additional  shares.
The cumulative  total return measures the change in value over the entire period
(for example,  ten years). An average annual total return shows the average rate
of return for each year in a period  that would  produce  the  cumulative  total
return over the entire period. However, average annual total returns do not show
the Fund's actual year-by-year performance.

      When total  returns  are quoted for Class A shares,  normally  the current
maximum initial sales charge has been deducted. When total returns are shown for
Class B or Class C shares,  normally the  contingent  deferred sales charge that
applies  to the  period  for which  total  return  is shown  has been  deducted.
However,  total  returns  may  also be  quoted  "at net  asset  value,"  without
considering  the effect of the sales charge,  and those returns would be less if
sales charges were deducted.

   
      |X| Yield.  Different  types of yields may be quoted to show  performance.
Each  Class  of  shares  calculates  its  standardized  yield  by  dividing  the
annualized  net investment  income per share from the portfolio  during a 30-day
period by the maximum offering price on the last day of the period. The yield of
each  Class  will  differ  because of the  different  expenses  of each Class of
shares.  The yield  data  represents  a  hypothetical  investment  return on the
portfolio, and does not measure an investment return based on dividends actually
paid to  shareholders.  To show that return, a dividend yield may be calculated.
Dividend  yield is  calculated  by dividing the  dividends of a class paid for a
stated  period by the maximum  offering  price on the last day of the period and
annualizing the result. Yields for Class A shares normally reflect the deduction
of the maximum initial sales charge, but may also be shown without deducting the
sales charge. Yields for Class B and Class C shares do not reflect the deduction
of the contingent deferred sales charge.  Tax-equivalent yield is the equivalent
yield that would be earned in the absence of income  taxes.  It is calculated by
dividing  that portion of the yield that is  tax-exempt by a factor equal to one
minus the applicable tax rate.

How Has the Fund  Performed?  Below is a discussion by the Manager of the Fund's
performance during its last fiscal year ended September 30, 1997,  followed by a
graphical  comparison of the Fund's  performance to an  appropriate  broad-based
market index.

      |X|  Management's  Discussion of Performance.  During the past fiscal year
ended  September 30, 1997 the Fund performed  well. The Fund's  performance  was
affected by volatile  interest rates which required  constant  adjustment of the
portfolio  duration.  Duration  describes a portfolio's  sensitivity to interest
rates.  The longer a portfolio's  duration,  the more  sensitive its price is to
change in interest  rates.  During this period  there were many periods in which
interest rates changed  direction.  This provided the Fund an opportunity to add
value to the portfolio by adjusting the portfolio's duration . In addition,  the
Fund  participated  in new issue  underwriting  during the occasional  period of
increased  supply in the municipal  market.  According to the laws of supply and
demand,  when the supply of bonds  increases,  their  prices tend to drop.  As a
result,  the Fund was able to buy bonds at attractive prices during this period.
The Fund's portfolio holdings, allocations and strategies are subject to change.

      |X| Comparing the Fund's  Performance to the Market. The graphs below show
the performance of a hypothetical  $10,000 investment in each class of shares of
the Fund held from the  inception of the Class until  September 30, 1997. In the
case of  Class A  shares,  performance  is  measured  from the  commencement  of
operations  on  November  11,  1986,  in the  case of Class B  shares,  from the
inception  of the class on May 3, 1993,  and in the case of Class C shares  from
inception  of the class on August 29,  1995.  In all cases,  all  dividends  and
capital gains  distributions  were reinvested in additional  shares.  The graphs
reflect the deduction of the 4.75% current maximum initial sales charge on Class
A shares, the maximum 5% contingent deferred sales charge on Class B shares, and
the 1% contingent deferred sales charge on Class C shares.
    

      The  Fund's  performance  is  compared  to  that  of the  Lehman  Brothers
Municipal Bond Index,  an unmanaged  index of a broad range of investment  grade
municipal bonds,  that is widely regarded as a measure of the performance of the
general municipal bond market.  Index  performance  reflects the reinvestment of
income but does not consider the effect of capital gains or  transaction  costs,
and none of the  data  below  shows  the  effect  of  taxes.  Also,  the  Fund's
performance  data reflects the effect 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 any one  index.  Moreover,  the index  performance  data does not
reflect any assessment of the risk of the investments included in the index.

The performance  information for the Lehman Brothers Municipal Bond Index in the
Class B graph begins on 4/30/93 and the Class C graph begins on 8/31/95.

1The inception  date of the Fund (Class A shares) was 11/11/86.  Class A returns
are shown net of the  applicable  4.75% maximum  initial sales charge.  2Class B
shares of the Fund were first  publicly  offered on 5/3/93.  The average  annual
total  returns   reflect   reinvestment  of  all  dividends  and  capital  gains
distributions and are shown net of the applicable 5% and 2% contingent  deferred
sales charges, respectively, for the one year period and life-of-the-class.  The
ending account value in the graph is net of the applicable 2% sales charge.

3Class C shares of the Fund were first publicly offered on 8/29/95. The one year
period is shown net of the applicable 1% contingent deferred sales charge.
    

Past performance is not predictive of future  performance.  Graphs are not drawn

How to Buy Shares

Classes of Shares.  The Fund offers investors three different classes of shares.
The different  classes of shares represent  investments in the same portfolio of
securities but are subject to different  expenses and will likely have different
share prices.

   
      o Class A  Shares.  If you buy Class A shares,  you pay an  initial  sales
charge (on investments up to $1 million). If you purchase Class A shares as part
of an  investment  of at least $1 million  in shares of one or more  Oppenheimer
funds,  you will not pay an initial sales  charge,  but if you sell any of those
shares  within 12 months of buying them (18 months if the shares were  purchased
prior to May 1, 1997),  you may pay a  contingent  deferred  sales  charge.  The
amount of that sales  charge  will vary  depending  on the amount you  invested.
These sales charges are described in "Buying Class A Shares" below.
    

      o Class B Shares.  If you buy Class B shares,  you pay no sales  charge at
the time of  purchase,  but if you sell your  shares  within six years of buying
them,  you will  normally pay a contingent  deferred  sales  charge.  That sales
charge varies  depending on how long you own your shares as described in "Buying
Class B Shares," below.

      o Class C Shares.  If you buy Class C shares,  you pay no sales  charge at
the time of  purchase,  but if you sell your  shares  within 12 months of buying
them,  you  will  normally  pay a  contingent  deferred  sales  charge  of 1% as
described in "Buying Class C Shares," below.

Which  Class of Shares  Should You  Choose?  Once you decide that the Fund is an
appropriate  investment  for you,  the  decisions as to which class of shares is
best  suited to your  needs  depends  on a number of  factors  which you  should
discuss with your financial advisor.  The Fund's operating costs that apply to a
class of shares and the effect of the  different  types of sales charges on your
investment  will vary your  investment  results  over time.  The most  important
factors  to  consider  are how much you plan to invest  and how long you plan to
hold your investment. If your goals and objectives change over time and you plan
to purchase  additional  shares,  you should re-evaluate those factors to see if
you should consider another class of shares.

      In the  following  discussion,  to help  provide  you and  your  financial
advisor  with a  framework  in  which  to  choose a  class,  we have  made  some
assumptions  using a  hypothetical  investment  in the  Fund.  We used the sales
charge rates that apply to each class,  and  considered the effect of the annual
asset-based  sales  charge  on Class B and  Class C  expenses  (which,  like all
expenses,  will affect your investment return).  For the sake of comparison,  we
have assumed that there is a 10% rate of  appreciation  in the  investment  each
year. Of course,  the actual  performance of your investment cannot be predicted
and will vary, based on the Fund's actual  investment  returns and the operating
expenses borne by each class of shares, and which class of shares you invest in.

      The factors  discussed  below are not intended to be investment  advice or
recommendations, because each investor's financial considerations are different.
The discussion below of the factors to consider in purchasing a particular class
of shares  assumes that you will  purchase  only one class of shares,  and not a
combination of shares of different classes.

      o How Long Do You Expect to Hold Your  Investment?  While future financial
needs cannot be predicted  with  certainty,  knowing how long you expect to hold
your investment  will assist you in selecting the  appropriate  class of shares.
Because of the effect of class-based  expenses,  your choice will also depend on
how much you plan to invest.  For example,  the reduced sales charges  available
for larger  purchases  of Class A shares  may,  over time,  offset the effect of
paying an initial sales charge on your  investment  (which reduces the amount of
your  investment  dollars used to buy shares for your  account)  compared to the
effect over time of higher class-based expenses on Class B or Class C shares for
which no initial sales charge is paid.

   
      o  Investing  for the  Short  Term.  If you have a short  term  investment
horizon (that is, you plan to hold your shares for not more than six years), you
should probably consider  purchasing Class A or Class C shares rather than Class
B shares  because of the effect of the Class B contingent  deferred sales charge
if you redeem within six years, as well as the effect of the Class B asset-based
sales charge on the investment return for that class in the short-term.  Class C
shares might be the appropriate  choice (especially for investments of less than
$100,000)  because there is no initial  sales charge on Class C shares,  and the
contingent  deferred  sales  charge  does not apply to  amounts  you sell  after
holding them one year.
    

      However,  if you plan to invest more than  $100,000 for the shorter  term,
then the more you invest and the more your investment  horizon  increases toward
six years,  Class C shares might not be as advantageous as Class A shares.  That
is because  the annual  asset-based  sales  charge on Class C shares will have a
greater  impact on your account over the longer term than the reduced  front-end
sales charge  available  for larger  purchases  of Class A shares.  For example,
Class A shares might be more  advantageous than Class C shares (as well as Class
B shares) for  investments of more than $100,000  expected to be held for 5 or 6
years (or more). For investments over $250,000  expected to be held 4 to 6 years
(or more).  Class A shares may become more advantageous than Class C shares (and
Class B  shares).  If  investing  $500,000  or more,  Class A shares may be more
advantageous as your investment horizon approaches 3 years or more.

      And for  investors  who invest $1 million or more,  in most cases  Class A
shares will be the most  advantageous  choice,  no matter how long you intend to
hold your shares.  For that reason,  the  Distributor  normally  will not accept
purchase  orders of  $500,000 or more of Class B shares or $1 million or more of
Class C shares, respectively, from a single investor.

      o Investing for the Longer Term. If you are investing for the longer term,
for example, for retirement,  and do not expect to need access to your money for
seven years or more, Class B shares may be an appropriate consideration,  if you
plan to invest less than $100,000. If you plan to invest more than $100,000 over
the long term,  Class A shares  will  likely be more  advantageous  than Class B
shares or Class C shares,  as  discussed  above,  because  of the  effect of the
expected lower expenses for Class A shares and the reduced initial sales charges
available  for larger  investments  in Class A shares  under the Fund's Right of
Accumulation.

      Of course,  these  examples are based on  approximations  of the effect of
current sales charges and expenses on a hypothetical investment over time, using
the assumed  annual  performance  return stated above,  and therefore you should
analyze your options carefully.

   
      o Are There  Differences in Account  Features That Matter to You?  Because
some account features , such as checkwriting, may not be available to Class B or
Class C shareholders, or other features (such as Automatic Withdrawal Plans) may
not be advisable (because of the effect of the contingent deferred sales charge)
for Class B or Class C shareholders, you should carefully review how you plan to
use your  investment  account  before  deciding  which  class of  shares to buy.
Additionally,  dividends  payable  to Class B and Class C  shareholders  will be
reduced by the additional  expenses borne by those classes that are not borne by
Class A  shares,  such as the  Class B and  Class C  asset-based  sales  charges
described  below  and  in  the  Statement  of  Additional   Information.   Share
certificates  are not  available  for  Class B or Class C shares  and if you are
considering  using your shares as collateral for a loan, that may be a factor to
consider.

      o How Does It Affect  Payments  to My  Broker?  A  salesperson,  such as a
broker, or any other person who is entitled to receive  compensation for selling
Fund shares may receive  different  compensation for selling one class of shares
than for selling another class.  It is important that investors  understand that
the  purpose of the Class B and Class C  contingent  deferred  sales  charge and
asset-based  sales  charges is the same as the  purpose of the  front-end  sales
charge on sales of Class A shares:  that is, to compensate the  Distributor  for
commissions it pays to dealers and financial  institutions  for selling  shares.
The Distributor may pay additional periodic  compensation from its own resources
to securities  dealers or financial  institutions based upon the value of shares
of the Fund owned by the dealer or financial  institution for its own account or
for its customers.

How Much Must You Invest?  You can open a Fund  account  with a minimum  initial
investment of $1,000 and make additional  investments at any time with as little
as $25. There are reduced minimum investments under special investment plans.
    

      With Asset Builder Plans,  Automatic Exchange Plans and military allotment
plans, you can make initial and subsequent investments for as little as $25; and
subsequent  purchases  of  at  least  $25  can  be  made  by  telephone  through
AccountLink.

      There is no minimum  investment  requirement  if you are buying  shares by
reinvesting  dividends from the Fund or other  Oppenheimer funds (a list of them
appears in the Statement of Additional  Information,  or you can ask your dealer
or  call  the  Transfer  Agent),  or  by  reinvesting  distributions  from  unit
investment trusts that have made arrangements with the Distributor.

      o How Are Shares Purchased?  You can buy shares several ways --through any
dealer,  broker or financial  institution  that has a sales  agreement  with the
Distributor,  or directly  through the Distributor,  or automatically  from your
bank  account   through  an  Asset  Builder  Plan  under  the   OppenheimerFunds
AccountLink service. The Distributor may appoint certain servicing agents as the
Distributor's  agent to accept purchase (and  redemption)  orders.  When you buy
shares,  be sure to specify  Class A,  Class B or Class C shares.  If you do not
choose, your investment will be made in Class A shares.

      o  Buying  Shares  Through  Your  Dealer.  Your  dealer  will
place your order with the Distributor on your behalf.

      o Buying Shares Through the Distributor.  Complete an OppenheimerFunds New
Account  Application  and return it with a check  payable  to  "OppenheimerFunds
Distributor,  Inc." Mail it to P.O. Box 5270,  Denver,  Colorado  80217.  If you
don't list a dealer on the  application,  the Distributor will act as your agent
in  buying  the  shares.  However,  it is  recommended  that  you  discuss  your
investment first with a financial advisor to be sure it is appropriate for you.

     o Payment by Federal  Funds Wire.  Shares may be purchased by Federal Funds
wire. The minimum  investment is $2,500.  You must first call the  Distributor's
Wire Department at  1-800-525-7041 to notify the Distributor of the wire, and to
receive further instructions.

   
      o  Buying  Shares  Through  OppenheimerFunds   AccountLink.  You  can  use
AccountLink  to link your Fund account  with an account at a U.S.  bank or other
financial  institution  that is an  Automated  Clearing  House  (ACH)  member to
transmit funds  electronically  to purchase  shares,  to have the Transfer Agent
send redemption proceeds or to transmit dividends and distributions to your bank
account.  Shares are purchased for your account on the regular  business day the
Distributor is instructed by you to initiate the ACH transfer to buy shares. You
can provide  those  instructions  automatically,  under an Asset  Builder  Plan,
described below, or by telephone instructions using OppenheimerFunds  PhoneLink,
also  described  below.  You  should  request  AccountLink   privileges  on  the
application or dealer  settlement  instructions  used to establish your account.
Please refer to "AccountLink" below for more details.
    

      o Asset Builder Plans. You may purchase shares of the Fund (and up to four
other Oppenheimer funds) automatically each month from your account at a bank or
other  financial  institution  under an Asset  Builder  Plan  with  AccountLink.
Details are in the Statement of Additional Information.

   
      o At What Price Are Shares  Sold?  Shares are sold at the public  offering
price based on the net asset value (and any initial  sales charge that  applies)
that is next  determined  after the  Distributor  receives the purchase order in
Denver, Colorado, or the order is received and transmitted to the Distributor by
an entity  authorized by the Fund to accept purchase or redemption  orders.  The
Fund has  authorized  the  Distributor,  certain  broker-dealers  and  agents or
intermediaries  designated by the Distributor or those  broker-dealers to accept
orders.  In most cases, to enable you to receive that day's offering price,  the
Distributor  or an authorized  entity must receive your order by the time of day
The New York Stock Exchange  closes,  which is normally 4:00 P.M., New York time
but may be earlier on some days (all  references to time in this Prospectus mean
"New York time").  The net asset value of each class of shares is  determined as
of that  time on each  day The New  York  Stock  Exchange  is open  (which  is a
"regular business day").

      If you buy shares through a dealer,  the dealer must receive your order by
the close of The New York Stock Exchange on a regular  business day and normally
your order must be transmitted to the  Distributor so that it is received before
the  Distributor's  close of business that day,  which is normally 5:00 P.M. The
Distributor,  in its sole  discretion,  may  reject any  purchase  order for the
Fund's shares.
    

Special Sales Charge  Arrangements for Certain  Persons.  The Appendix A in this
prospectus  sets forth  conditions for the waiver of, or exemption  from,  sales
charges or the special  sales  charge rates that apply to purchases of shares of
the Fund (including  purchases by exchange) by a person who was a shareholder of
one of the former Quest for Value Funds (as defined in that Appendix).

   
Buying Class A Shares. Class A shares are sold at their offering price, which is
normally net asset value plus an initial sales charge.  However,  in some cases,
described below,  purchases are not subject to an initial sales charge,  and the
offering price will be the net asset value. In some cases, reduced sales charges
may be available,  as described  below.  Out of the amount you invest,  the Fund
receives the net asset value to invest for your account. The sales charge varies
depending on the amount of your  purchase.  A portion of the sales charge may be
retained by the Distributor  and paid to your dealer as commission.  The current
sales charge rates and commissions paid to dealers and brokers are as follows:
    

                     Front-End      Front-End
                     Sales Charge   Sales Charge    Commission

Less than $50,000    4.75%          4.98%           4.00%
- -----------------------------------------------------------------------
   
$50,000 or more but       4.50%           4.71%          4.00%
less than $100,000
    
- -----------------------------------------------------------------------
   
$100,000 or more but      3.50%           3.63%          3.00%
less than $250,000
    
- -----------------------------------------------------------------------

   
$250,000 or more but      2.50%           2.56%          2.25%
less than $500,000
    
- -----------------------------------------------------------------------
   
$500,000 or more but      2.00%           2.04%          1.80%
less than $1 million
    

      The  Distributor  reserves the right to reallow the entire  commission  to
dealers.  If that occurs,  the dealer may be considered an  "underwriter"  under
Federal securities laws.

      o Class A Contingent  Deferred  Sales  Charge.  There is no initial  sales
charge  on  purchases  of Class A shares  of any one or more of the  Oppenheimer
funds  aggregating  $1 million or more. The  Distributor  pays dealers of record
commissions  on those non-  retirement  plan purchases in an amount equal to the
sum of 1.0%.  That commission will be paid only on the amount of those purchases
that  were not  previously  subject  to a  front-end  sales  charge  and  dealer
commission.

   
      If you redeem any of those shares  purchased prior to May 1, 1997,  within
18 months  of the end of the  calendar  month of their  purchase,  a  contingent
deferred  sales charge  (called the "Class A contingent  deferred sales charge")
may be deducted  from the  redemption  proceeds.  A Class A contingent  deferred
sales charge may be deducted from the redemption proceeds of any of those shares
purchased on or after May 1, 1997 that are redeemed  within 12 months of the end
of the calendar month of their purchase.  That sales charge may be equal to 1.0%
of the lesser of (1) the aggregate  net asset value of the redeemed  shares (not
including  shares  purchased  by  reinvestment  of  dividends  or  capital  gain
distributions)  or (2) the  original  offering  price (which is the original net
asset value) of the redeemed shares.  However,  the Class A contingent  deferred
sales  charge  will not  exceed  the  aggregate  amount of the  commissions  the
Distributor  paid to your dealer on all Class A shares of all Oppenheimer  funds
you  purchased  subject to the Class A  contingent  deferred  sales  charge.  In
determining whether a contingent deferred sales charge is payable, the Fund will
first redeem shares that are not subject to the sales charge,  including  shares
purchased by reinvestment  of dividends and capital gains,  and then will redeem
other  shares in the  order  that you  purchased  them.  The Class A  contingent
deferred sales charge is waived in certain cases  described in "Waivers of Class
A Sales Charges" below.

      No Class A  contingent  deferred  sales  charge is charged on exchanges of
shares under the Fund's Exchange Privilege  (described below).  However,  if the
shares  acquired by exchange are redeemed  within 12 calendar  months (18 months
for shares  purchased  prior to May 1, 1997) of the end of the calendar month of
the purchase of the exchanged shares, the sales charge will apply.
    

      o Special  Arrangements With Dealers. The Distributor may advance up to 13
months' commissions to dealers that have established  special  arrangements with
the Distributor for Asset Builder Plans for their clients.

     Reduced Sales Charges for Class A Share  Purchases.  You may be eligible to
buy Class A shares at reduced sales charge rates in one or more of the following
ways:

      o Right of Accumulation.  To qualify for the lower sales charge rates that
apply to  larger  purchases  of Class A  shares,  you and  your  spouse  can add
together Class A and Class B shares you purchase for your  individual  accounts,
or jointly,  or for trusts or custodial  accounts on behalf of your children who
are minors.  A fiduciary can count all shares  purchased for a trust,  estate or
other  fiduciary  account  (including one or more employee  benefit plans of the
same employer) that has multiple accounts.

   
      Additionally,  you can add together current purchases of Class A and Class
B shares of the Fund and other Oppenheimer funds to reduce the sales charge rate
that applies to current purchases of Class A shares.  You can also include Class
A and Class B shares of Oppenheimer funds you previously purchased subject to an
initial or contingent  deferred sales charge to reduce the sales charge rate for
current  purchases  of  Class A  shares,  provided  that  you  still  hold  your
investment in one of the Oppenheimer  funds. The Distributor will add the value,
at current offering price, of the shares you previously  purchased and currently
own to the value of current  purchases to  determine  the sales charge rate that
applies.  The  Oppenheimer  funds are listed in "Reduced  Sales  Charges" in the
Statement  of  Additional  Information,  or a list  can  be  obtained  from  the
Distributor.  The reduced sales charge will apply only to current  purchases and
must be requested when you buy your shares.
    

     o Letter of  Intent.  Under a Letter of  Intent,  if you  purchase  Class A
shares or Class A and Class B shares  of the Fund and  other  Oppenheimer  funds
during a 13-month  period,  you can reduce the sales charge rate that applies to
your purchases of Class A shares. The total amount of your intended purchases of
both Class A and Class B shares will determine the reduced sales charge rate for
the Class A shares purchased during that period. This can include purchases made
up to 90 days before the date of the Letter.  More  information  is contained in
the  Application  and in "Reduced  Sales Charges" in the Statement of Additional
Information.

   
      o Waivers  of Class A Sales  Charges.  The Class A sales  charges  are not
imposed in the  circumstances  described below.  There is an explanation of this
policy in "Reduced Sales Charges" in the Statement of Additional Information. In
order to receive a waiver of the Class A contingent  deferred sales charge,  you
must notify the Transfer Agent which conditions apply.
    

      Waivers of Initial  and  Contingent  Deferred  Sales  Charges  for Certain
Purchasers.  Class A shares purchased by the following investors are not subject
to any Class A sales charges:

      o the Manager or its affiliates;

   
      o present or former officers, directors, trustees and employees (and their
      "immediate  families"  as  defined  in  "Reduced  Sales  Charges"  in  the
      Statement  of  Additional  Information)  of the Fund,  the Manager and its
      affiliates; and retirement plans established by them for their employees;
    

      o registered  management  investment  companies,  or separate  accounts of
      insurance   companies   having  an  agreement  with  the  Manager  or  the
      Distributor for that purpose;

   
      o dealers or brokers that have a sales agreement with the Distributor,  if
      they purchase shares for their own accounts;  or for retirement  plans for
      their employees;
    

      o employees and registered  representatives (and their spouses) of dealers
      or brokers  described  above or financial  institutions  that have entered
      into sales  arrangements  with such dealers or brokers (and are identified
      to the Distributor) or with the Distributor; the purchaser must certify to
      the  Distributor  at the time of  purchase  that the  purchase  is for the
      purchaser's own account (or for the benefit of such  employee's  spouse or
      minor children);

   
      o dealers,  brokers, banks or registered investment advisers advisors that
      have entered into an agreement with the Distributor providing specifically
      for the use of shares of the Fund in particular  investment  products made
      available to their clients (those clients may be charged a transaction fee
      by their dealer, broker, bank, or advisor for the purchase or sale of Fund
      shares); o (1) investment advisors and financial planners who have entered
      into an agreement for this purpose with the  Distributor and who charge an
      advisory,  consulting  or other fee for their  services and buy shares for
      their own accounts or the accounts of their  clients,  (2) "rabbi  trusts"
      that buy shares for their own  accounts,  in each case if those  purchases
      are made through a broker or agent or other  financial  intermediary  that
      has made special  arrangements  with the Distributor for those  purchases;
      and (3) clients of such  investment  advisors or financial  planners (that
      have entered into an agreement for this purpose with the  Distributor) who
      buy shares for their own accounts may also purchase  shares  without sales
      charge but only if their  accounts are linked to a master account of their
      investment  advisor or  financial  planner on the books and records of the
      broker,  agent or financial  intermediary  with which the  Distributor has
      made such special  arrangements  (each of these investors may be charged a
      fee by the broker, agent or financial intermediary for purchasing shares);
    

      o directors,  trustees,  officers or full-time employees of OpCap Advisors
      or its affiliates,  their relatives or any trust, pension,  profit sharing
      or other benefit plan which beneficially owns shares for those persons;

   
      o accounts for which  Oppenheimer  Capital is the investment  advisor (the
      Distributor  must be  advised of this  arrangement)  and  persons  who are
      directors  or trustees  of the  company or trust  which is the  beneficial
      owner of such accounts; or
    

      o any unit investment trust that has entered into an appropriate agreement
      with the Distributor.

      Waivers  of  Initial  and  Contingent  Deferred  Sales  Charges in Certain
Transactions.  Class A shares issued or purchased in the following  transactions
are not subject to Class A sales charges:

      o shares  issued  in  plans  of  reorganization,  such as  mergers,  asset
acquisitions and exchange offers, to which the Fund is a party;
      o shares purchased by the reinvestment of dividends or other distributions
reinvested from the Fund or other Oppenheimer funds (other than Oppenheimer Cash
Reserves) or unit investment  trusts for which  reinvestment  arrangements  have
been made with the
Distributor;
   
      o shares  purchased  and paid for with the proceeds of shares  redeemed in
the prior 30 days from a mutual fund  (other than a fund  managed by the Manager
or any of its  subsidiaries)  on which an  initial  sales  charge or  contingent
deferred sales charge was paid (this waiver also applies to shares  purchased by
exchange of shares of  Oppenheimer  Money Market Fund,  Inc. that were purchased
and paid for in this  manner);  this waiver must be requested  when the purchase
order is placed for your  shares of the Fund,  and the  Distributor  may require
evidence of your qualification for this waiver; or
    
      o shares purchased with the proceeds of maturing principal of units of any
Qualified Unit Investment Liquid Trust Series;

      Waivers  of the Class A  Contingent  Deferred  Sales  Charge  for  Certain
Redemptions.  The Class A  contingent  deferred  sales  charge is also waived if
shares that would  otherwise be subject to the contingent  deferred sales charge
are redeemed in the following cases:

      o to make Automatic  Withdrawal Plan payments that are limited annually to
no more than 12% of the original account value,
      o  involuntary  redemptions  of shares by operation of law or  involuntary
redemptions of small accounts (see "Shareholder Account Rules and Policies"); or
   
      o if, at the time of purchase of shares  (prior to May 1, 1997) the dealer
agrees in writing  to accept the  dealer's  portion of the sales  commission  in
installments  of 1/18th of the commission  per month (and no further  commission
will be payable if the shares are redeemed within 18 months of purchase);
      o if, at the time of  purchase of shares (if  purchased  during the period
May 1, 1997 through  December  31, 1997) the dealer  agrees in writing to accept
the dealer's  portion of the sales  commission in  installments of 1/12th of the
commission  per month (and no further  commission  will be payable if the shares
are redeemed within 12 months of purchase);
    

      o Service Plan for Class A Shares. The Fund has adopted a Service Plan for
Class A shares to reimburse the  Distributor for a portion of its costs incurred
in connection  with the personal  service and  maintenance of 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. The
Distributor  uses all of those fees to compensate  dealers,  brokers,  banks and
other  financial  institutions  quarterly  for  providing  personal  service and
maintenance  of  accounts  of their  customers  that hold  Class A shares and to
reimburse   itself   (if  the  Fund's   Board  of   Trustees   authorizes   such
reimbursements,  which it has not yet done) for its other expenditures under the
Plan.

      Services  to  be  provided  include,  among  others,   answering  customer
inquiries about the Fund,  assisting in establishing and maintaining accounts in
the Fund,  making the Fund's  investment  plans  available and  providing  other
services at the request of the Fund or the Distributor. Payments are made by the
Distributor  quarterly  at an  annual  rate not to exceed  0.25% of the  average
annual net assets of Class A shares held in accounts of the service providers or
their  customers.  The payments  under the Plan increase the annual  expenses of
Class A  shares  by up to 0.25%  of its  average  annual  net  assets.  For more
details,  please refer to  "Distribution  and Service Plans" in the Statement of
Additional Information.

Buying  Class B Shares.  Class B shares  are sold at net  asset  value per share
without an initial sales charge.  However, if Class B shares are redeemed within
6 years of their purchase,  a contingent  deferred sales charge will be deducted
from the  redemption  proceeds.  That  sales  charge  will not  apply to  shares
purchased by the reinvestment of dividends or capital gains  distributions.  The
contingent  deferred  sales  charge will be based on the lesser of the net asset
value of the redeemed shares at the time of redemption or the original  offering
price (which is the original net asset value).  The  contingent  deferred  sales
charge is not imposed on the amount of your  account  value  represented  by the
increase  in net  asset  value  over the  initial  purchase  price.  The Class B
contingent  deferred sales charge is paid to compensate the  Distributor for its
expenses of providing  distribution-related  services to the Fund in  connection
with the sale of Class B shares.

   
      To determine  whether the  contingent  deferred  sales charge applies to a
redemption,  the Fund redeems shares in the following order: (1) shares acquired
by  reinvestment  of dividends and capital gains  distributions,  and (2) shares
held the longest during the 6- year period. The contingent deferred sales charge
is not imposed in the circumstances described in "Waivers of Class B and Class C
Sales Charges," below.
    

      The amount of the  contingent  deferred  sales  charge  will depend on the
number  of years  since you  invested  and the  dollar  amount  being  redeemed,
according to the following schedule:

                                       Contingent Deferred
                                       Sales Charge
Years Since Beginning of Month in      On Redemptions in That Year
which Purchase Order Was Accepted      (As % of Amount  Subject  to
Charge)
- -----------------------------------------------------------------------
0-1                                    5.0%
- -----------------------------------------------------------------------

- -----------------------------------------------------------------------
6 and following                        None

      In the table, a "year" is a 12-month period.  All purchases are considered
to have been made on the first  regular  business  day of the month in which the
purchase was made.

      |X| Automatic  Conversion of Class B Shares.  72 months after you purchase
Class B shares, those shares will automatically  convert to Class A shares. This
conversion feature relieves Class B shareholders of the asset-based sales charge
that applies to Class B shares under the Class B Distribution  and Service Plan,
described  below. The conversion is based on the relative net asset value of the
two classes,  and no sales load or other charge is imposed.  When Class B shares
convert,  any other Class B shares that were  acquired  by the  reinvestment  of
dividends and distributions on the converted shares will also convert to Class A
shares. The conversion feature is subject to the continued availability of a tax
ruling described in "Alternative Sales Arrangements - Class A, Class B and Class
C Shares" in the Statement of Additional Information.

       
Buying  Class C Shares.  Class C shares  are sold at net  asset  value per share
without an initial sales charge.  However, if Class C shares are redeemed within
12 months of their purchase,  a contingent deferred sales charge of 1.0% will be
deducted  from the  redemption  proceeds.  That sales  charge  will not apply to
shares   purchased  by  the   reinvestment   of   dividends  or  capital   gains
distributions.  The contingent deferred sales charge will be based on the lesser
of the net asset value of the redeemed  shares at the time of  redemption or the
original offering price (which is the original net asset value).  The contingent
deferred  sales  charge  is not  imposed  on the  amount of your  account  value
represented by the increase in net asset value over the initial  purchase price.
The  Class  C  contingent  deferred  sales  charge  is paid  to  compensate  the
Distributor for its expenses of providing  distribution-related  services to the
Fund in connection with the sale of Class C shares.

      To determine  whether the  contingent  deferred  sales charge applies to a
redemption,  the Fund redeems shares in the following order: (1) shares acquired
by  reinvestment of dividends and capital gains  distributions,  (2) shares held
for over 12 months, and (3) shares held the longest during the 12-month period.

     Distribution and Service Plans for Class B and Class C Shares. The Fund has
adopted  Distribution  and  Service  Plans  for  Class B and  Class C shares  to
compensate  the  Distributor  for  distributing  Class B and Class C shares  and
servicing  accounts.  Under the Plans,  the Fund pays the  Distributor an annual
"asset-based  sales  charge"  of 0.75% per year on Class B shares and on Class C
shares. The Distributor also receives a service fee of 0.25% per year under each
plan.

   
      Under each Plan,  both fees are  computed  on the average of the net asset
value of  shares in the  respective  class,  determined  as of the close of each
regular business day during the period. The asset-based sales charge and service
fees  increase  Class B and Class C expenses by 1.00% of the net assets per year
of the respective class.

      The Distributor uses the service fees to compensate  dealers for providing
personal and account  maintenance  services  for  accounts  that hold Class B or
Class C shares.  Those  services are similar to those provided under the Class A
Service Plan,  described  above.  The Distributor pays the 0.25% service fees to
dealers in advance  for the first year after Class B or Class C shares have been
sold by the dealer and  retains  the  service fee paid by the Fund in that year.
After the shares  have been held for a year,  the  Distributor  pays the service
fees to dealers on a quarterly basis.
    

      The  asset-based  sales charge allows  investors to buy Class B or Class C
shares  without a front-end  sales charge  while  allowing  the  Distributor  to
compensate  dealers that sell those shares.  The Fund pays the asset-based sales
charges to the Distributor for its services rendered in distributing Class B and
Class C shares.  Those  payments  are at a fixed rate that is not related to the
Distributor's  expenses. The services rendered by the Distributor include paying
and financing the payment of sales commissions,  service fees and other costs of
distributing and selling Class B and Class C shares.

   
      The Distributor  currently pays sales commissions of 3.75% of the purchase
price of Class B shares to dealers  from its own  resources at the time of sale.
Including  the  advance  of the  service  fee,  the  total  amount  paid  by the
Distributor to the dealer at the time of sales of Class B shares is 4.00% of the
purchase price.  The Distributor  retains the Class B asset-based  sales charge.
The Distributor may pay the Class B service fee and the asset-based sales charge
to the dealer  quarterly in lieu of paying the sales  commission and service fee
advance at the time of purchase.

      The Distributor  currently pays sales commissions of 0.75% of the purchase
price to dealers  from its own  resources at the time of sale of Class C shares.
Including  the  advance  of the  service  fee,  the  total  amount  paid  by the
Distributor  to the dealer at the time of sale of Class C shares is 1.00% of the
purchase price. The Distributor  plans to pay the asset-based sales charge as an
ongoing  commission  to the dealer on Class C shares that have been  outstanding
for a year  or  more.  The  Distributor  may pay the  Class  C  service  fee and
asset-based  sales  charge to the dealer  quarterly  in lieu of paying the sales
commission and service fee advance at the time of purchase.

      The  Distributor's  actual  expenses in selling Class B and Class C shares
may be more than the payments it receives from contingent deferred sales charges
collected  on  redeemed  shares  and from the Fund  under the  Distribution  and
Service  Plans for Class B and Class C  shares.  If the Fund  terminates  either
Plan,  the Board of  Trustees  may allow the Fund to  continue  payments  of the
asset-based  sales charge to the Distributor for distributing  shares before the
Plan was  terminated.  At September 30, 1997,  the end of the Class B Plan year,
the Distributor had incurred  unreimbursed  expenses in connection with sales of
Class B shares of $695,667 (equal to 3.48%, of the Fund's net assets represented
by Class B shares on that date).  At September 30, 1997,  the end of the Class C
Plan year, the Distributor had incurred unreimbursed expenses in connection with
sales of Class C shares of  $36,319  (equal to 1.42%,  of the  Fund's net assets
represented by Class C shares on that date).

      o Waivers  of Class B and Class C Sales  Charges.  The Class B and Class C
contingent  deferred  sales  charge will not be applied to shares  purchased  in
certain types of  transactions  nor will it apply to shares  redeemed in certain
circumstances  as described  below.  The reasons for this policy are in "Reduced
Sales Charges" in the Statement of Additional Information. In order to receive a
waiver of the Class B and Class C contingent  deferred  sales  charge,  you must
notify the Transfer Agent which conditions apply.
    

      Waivers for Redemptions of Shares in Certain Cases.  The Class B and Class
C contingent  deferred sales charges will be waived for redemptions of shares in
the following cases:

   
      o redemptions from accounts  following the death or disability of the last
surviving  shareholder,  including a trustee of a "grantor"  trust or  revocable
living  trust for which the trustee is also the sole  beneficiary  (the death or
disability  must  have  occurred  after  the  account  was  established  and for
disability  you must provide  evidence of a  determination  of disability by the
Social Security Administration); and

      o shares  redeemed  involuntarily,  as described in  "Shareholder  Account
Rules and Policies" below.
    

     Waivers for Shares Sold or Issued in Certain  Transactions.  The contingent
deferred  sales  charge is also  waived  on Class B and  Class C shares  sold or
issued in the following cases:

     o shares sold to the Manager or its affiliates; o shares sold to registered
management  investment  companies or separate  accounts of  insurance  companies
having an agreement with the Manager or the Distributor  for that purpose;  or o
shares issued in plans of reorganization to which the Fund is a party.

redemption proceeds.  No dividends are accrued or paid on the proceeds of shares
that have been redeemed and are awaiting  transmittal by wire. To establish wire
redemption privileges on an account that is already established,  please contact
the Transfer Agent for instructions.

redemption request, call the Transfer Agent at 1-800-525-7048.

Transfer  Agent for  signature  cards,  which must be signed  (with a  signature
guarantee)  by all owners of the account and returned to the  Transfer  Agent so
that  checks can be sent to you to use.  Shareholders  with joint  accounts  can
elect in writing to have checks  paid over the  signature  of one owner.  If you
previously  signed  a  signature  card  to  establish  checkwriting  in  another
Oppenheimer  fund,  simply call  1-800-525-7048  to request  checkwriting for an
account in this Fund with the same  registration  as the  previous  checkwriting

your account value.
      Remember:  your  shares  fluctuate  in value  and you  should
not write a check close to the total account value.
      o You may not write a check that would  require the Fund to redeem  shares
that were purchased by check or Asset Builder Plan
payments within the prior 10 days.
      o Don't use your  checks  if you  changed  your Fund  account
number.

       
How to Exchange Shares

      Shares of the Fund may be  exchanged  for  shares of  certain  Oppenheimer
funds at net  asset  value  per  share at the time of  exchange,  without  sales
charge. To exchange shares, you must meet
several conditions:

      o Shares of the fund  selected for exchange  must be available for sale in
your state of residence.
      o The  prospectuses of this Fund and the fund whose shares you want to buy
must offer the exchange privilege.
      o You must hold the shares you buy when you establish  your account for at
least 7 days before you can exchange them; after the account is open 7 days, you
can exchange shares every regular
business day.
      o You  must  meet  the  minimum  purchase  requirements  for the  fund you
purchase by exchange.
      o  Before  exchanging  into a fund,  you  should  obtain  and
read its prospectus.

      Shares of a particular  class of the Fund may be exchanged only for shares
of the same class in the other Oppenheimer funds. For example,  you can exchange
Class A shares of this Fund only for Class A shares of another fund. At present,
Oppenheimer  Money Market Fund,  Inc.  offers only one class of shares which are
considered to be Class A shares for this purpose.  In some cases,  sales charges
may be  imposed  on  exchange  transactions.  Please  refer to "How to  Exchange
Shares" in the Statement of Additional Information for more details.

      Exchanges may be requested in writing or by telephone:

     o Written Exchange Requests.  Submit an  OppenheimerFunds  Exchange Request
form, signed by all owners of the account.  Send it to the Transfer Agent at the
addresses listed in "How to Sell Shares."

     o Telephone  Exchange  Requests.  Telephone  exchange  requests may be made
either by  calling  a  service  representative  at  1-800-852-  8457 or by using
PhoneLink  for  automated  exchanges  by  calling  1-  800-533-3310.   Telephone
exchanges may be made only between  accounts that are  registered  with the same
name(s) and  address.  Shares held under  certificates  may not be  exchanged by
telephone.

     You can find a list of Oppenheimer funds currently  available for exchanges
in the  Statement of Additional  Information  or obtain one by calling a service
representative at 1-800-525-7048. That list can change from time to time.

      There are certain exchange policies you should be aware of:

      o Shares are normally  redeemed from one fund and purchased from the other
fund in the exchange  transaction on the same regular  business day on which the
Transfer Agent receives an exchange  request that is in proper form by the close
of The New York Stock Exchange that day, which is normally 4:00 P.M., but may be
earlier on some days.  However,  either fund may delay the purchase of shares of
the fund you are  exchanging  into up to seven days if it determines it would be
disadvantaged by a same-day transfer of the proceeds to buy shares. For example,
the receipt of multiple  exchange  requests  from a dealer in a  "market-timing"
strategy  might  require  the sale of  portfolio  securities  at a time or price
disadvantageous to the Fund.

     o  Because   excessive   trading  can  hurt  fund   performance   and  harm
shareholders,  the Fund  reserves the right to refuse any exchange  request that
will  disadvantage it, or to refuse multiple  exchange  requests  submitted by a
shareholder or dealer.

     o The Fund may amend,  suspend or terminate  the exchange  privilege at any
time.  Although  the Fund will  attempt to provide  you  notice  whenever  it is
reasonably able to do so, it may impose these changes at any time.

      o For tax purposes, exchanges of shares involve a redemption of the shares
of the fund you own and a purchase  of the shares of the other  fund,  which may
result in a capital gain or loss.  For more  information  about taxes  affecting
exchanges,  please  refer  to "How to  Exchange  Shares,"  in the  Statement  of
Additional Information.

      o If the Transfer Agent cannot exchange all the shares you request because
of a  restriction  cited above,  only the shares  eligible for exchange  will be
exchanged.

      o Net Asset Value Per Share is  determined  for each class of shares as of
the close of The New York Stock Exchange, which is normally 4:00 p.m. but may be
earlier on some days on each day the  Exchange is open by dividing  the value of
the Fund's net  assets  attributable  to a class by the number of shares of that
class that are  outstanding.  The  Trust's  Board of  Trustees  has  established
procedures  to value the Fund's  securities  to determine  net asset  value.  In
general,  securities  values  are  based on  market  value.  There  are  special
procedures for valuing illiquid and restricted  securities,  and obligations for
which market values cannot be readily  obtained.  These procedures are described
more completely in the Statement of Additional Information.

      o The offering of shares may be  suspended  during any period in which the
determination of net asset value is suspended, and the offering may be suspended
by the Board of Trustees at any time the Board believes it is in the Fund's best
interest to do so.

      o Telephone Transaction Privileges for purchases, redemptions or exchanges
may be modified,  suspended or terminated by the Fund at any time. If an account
has  more  than one  owner,  the Fund  and the  Transfer  Agent  may rely on the
instructions of any one owner.  Telephone  privileges apply to each owner of the
account and the dealer representative of record for the account unless and until
the  Transfer  Agent  receives  cancellation  instructions  from an owner of the
account.

      o The  Transfer  Agent will  record  any  telephone  calls to verify  data
concerning  transactions  and has  adopted  other  procedures  to  confirm  that
telephone  instructions  are  genuine,  by  requiring  callers  to  provide  tax
identification  numbers  and  other  account  data  or by  using  PINs,  and  by
confirming  such  transactions  in writing.  If the Transfer  Agent does not use
reasonable   procedures  it  may  be  liable  for  losses  due  to  unauthorized
transactions,  but  otherwise  neither the  Transfer  Agent nor the Fund will be
liable for losses or expenses arising out of telephone  instructions  reasonably
believed to be genuine.  If you are unable to reach the  Transfer  Agent  during
periods of unusual market activity,  you may not be able to complete a telephone
transaction and should consider placing your order by mail.

      o Redemption  or transfer  requests will not be honored until the Transfer
Agent  receives all required  documents in proper form.  From time to time,  the
Transfer  Agent in its  discretion  may waive  certain of the  requirements  for
redemptions stated in this Prospectus.

      o Dealers  that can  perform  account  transactions  for their  clients by
participating in NETWORKING through the National Securities Clearing Corporation
are  responsible  for  obtaining  their  clients'  permission  to perform  those
transactions  and are  responsible to their clients who are  shareholders of the
Fund if the dealer performs any transaction erroneously or improperly.

      o The  redemption  price for shares  will vary from day to day because the
value of the securities in the Fund's portfolio  fluctuates,  and the redemption
price,  which is the net asset value per share,  will  normally be different for
Class A, Class B and Class C shares.  Therefore,  the  redemption  value of your
shares may be more or less than their original cost.

   
      o Payment for redeemed  shares is made ordinarily in cash and forwarded by
check or through AccountLink (as elected by the shareholder under the redemption
procedures  described above) within seven days after the Transfer Agent receives
redemption  instructions  in proper  form,  except under  unusual  circumstances
determined by the Securities and Exchange Commission delaying or suspending such
payments.  For accounts registered in the name of a broker-dealer,  payment will
be forwarded within three business days. The Transfer Agent may delay forwarding
a check or processing a payment via AccountLink for recently  purchased  shares,
but only until the purchase payment has cleared. That delay may be as much as 10
days from the date the shares were  purchased.  That delay may be avoided if you
purchase shares by federal funds wire, certified check or arrange with your bank
to  provide  telephone  or written  assurance  to the  Transfer  Agent that your
purchase payment has cleared.
    

      o Involuntary redemptions of small accounts may be made by the Fund if the
account  value has fallen  below $200 for  reasons  other than the fact that the
market value of shares has dropped,  and in some cases  involuntary  redemptions
may be made to repay the Distributor  for losses from the  cancellation of share
purchase orders.

      o Under  unusual  circumstances,  shares of the Fund may be  redeemed  "in
kind," which means that the  redemption  proceeds  will be paid with  securities
from the Fund's portfolio. Please refer to "How to Sell Shares" in the Statement
of Additional Information for more details.

   
      o "Backup Withholding" of Federal income tax may be applied at the rate of
31% from taxable  dividends,  distributions and redemption  proceeds  (including
exchanges)  if you fail to furnish  the Fund a correct  and  properly  certified
Social   Security  or  Employer   Identification   Number  when  you  sign  your
application, or if you underreport your income to the Internal Revenue Service .
    

      o The Fund does not charge a redemption  fee, but if your dealer or broker
handles  your  redemption,  they may  charge a fee.  That fee can be  avoided by
redeeming  your Fund shares  directly  through  the  Transfer  Agent.  Under the
circumstances  described  in  "How  To Buy  Shares,"  you  may be  subject  to a
contingent  deferred  sales charge when  redeeming  certain Class A, Class B and
Class C shares.

      o To avoid sending  duplicate copies of materials to households,  the Fund
will mail only one copy of each annual and  semi-annual  report to  shareholders
having  the same last name and  address  on the Fund's  records.  However,  each
shareholder may call the Transfer Agent at  1-800-525-7048 to ask that copies of
those materials be sent personally to that shareholder.


Dividends, Capital Gains and Taxes

Dividends. The Fund declares dividends separately for Class A, Class B and Class
C shares from net investment  income on each regular business day and pays those
dividends to  shareholders  monthly on a date selected by the Board of Trustees.
Dividends  paid on Class A shares  generally  are expected to be higher than for
Class B or  Class C  shares  because  expenses  allocable  to Class B or Class C
shares will generally be higher.

   
      During the Fund's fiscal year ended September 30, 1997, the Fund sought to
pay  distributions  to  shareholders  at a targeted level per Class A share each
month,  to the extent that target was consistent  with the Fund's net investment
income  and  other  distributable   income  sources,   although  the  amount  of
distributions could vary from time to time, depending on market conditions,  the
composition of the Fund's portfolio,  and expenses borne by that Class. The Fund
was able to pay dividends at the targeted level from net  investment  income and
other  distributable  income,  without  any  material  impact  on the  Manager's
portfolio  management  practices or on the Fund's net asset value per share. The
Board of Trustees  could change that  targeted  level at any time,  and there is
otherwise no fixed dividend rate. There can be no assurance as to the payment of
any dividends or the realization of any capital gains.
    

Capital  Gains.  Although  the Fund does not seek  capital  gains,  the Fund may
realize  capital gains on the sale of portfolio  securities.  If it does, it may
make  distributions  annually in December out of any net short-term or long-term
capital gains.  The Fund may also make  supplemental  distributions of dividends
and capital gains  following  the end of its fiscal year. If net capital  losses
are realized in any year, they are charged against principal and not against net
investment income,  which is distributed  regardless of capital gains or losses.
Long-term capital gains will be separately identified in the tax information the
Fund sends you after the end of the calendar year.  Short-term capital gains are
treated as taxable dividends for tax purposes.

     Distribution  Options.  When  you  open  your  account,   specify  on  your
application how you want to receive your distributions. You have four options:

     o Reinvest  All  Distributions  in the Fund.  You can elect to reinvest all
dividends and long-term capital gains  distributions in additional shares of the
Fund.  
     o  Reinvest  Long-Term  Capital  Gains  Only.  You can elect to  reinvest
long-term  capital gains in the Fund while receiving  dividends by check or sent
to your bank account on AccountLink.  o Receive All  Distributions  in Cash. You
can elect to  receive a check for all  dividends  and  long-term  capital  gains
distributions or have them sent to your bank on AccountLink.
   
      o Reinvest Your  Distributions  in Another  Oppenheimer  Fund
Account. You can  reinvest  all  distributions  in the  same  class
of shares  of   another   Oppenheimer   fund   account   you   have
established.

Taxes.  Long-term  capital  gains are taxable as  long-term  capital  gains when
distributed to  shareholders.  It does not matter how long you held your shares.
Dividends  paid from  short-term  capital gains are taxable as ordinary  income.
Dividends  paid  from net  investment  income  earned  by the Fund on  Municipal
Securities  will be  excludable  from your gross  income for Federal  income tax
purposes.  A  portion  of the  dividends  paid by the Fund may be an item of tax
preference if you are subject to alternative  minimum tax. Taxable dividends and
distributions  are subject to federal  income tax and may be subject to state or
local taxes.  Whether you reinvest your  distributions  in additional  shares or
take them in cash, the tax treatment is the same.  Every year the Fund will send
you and the IRS a statement  showing the amount of any taxable  distribution you
received  in the  previous  year  as  well  as the  amount  of  your  tax-exempt
dividends.  So that the  Fund  will not  have to pay  taxes  in the  amounts  it
distributes to shareholders as dividends and capital gains,  the Fund intends to
manage  its  investments  so that it will  qualify  as a  "regulated  investment
company" under the Internal Revenue Code,  although it reserves the right not to
qualify in a particular year.

      o "Buying  a  Dividend":  If you buy  shares  on or just  before  the Fund
declares  a  capital  gains  distribution,  you will pay the full  price for the
shares and then receive a portion of the price back as a taxable  capital  gain.
To the extent the Fund's dividends include taxable income, you will pay taxes on
that portion of the dividend.
    

     o Taxes on Transactions:  Even though the Fund seeks tax-exempt  income for
distribution to shareholders,  you may have a capital gain or loss when you sell
or exchange your shares.  A capital gain or loss is the  difference  between the
price you paid for the shares and the price you received when you sold them. Any
capital gain is subject to capital gains tax.

      o Returns of Capital: In certain cases, distributions made by the Fund may
be considered a non-taxable  return of capital to shareholders.  If that occurs,
it will be  identified  in  notices to  shareholders.  A  non-taxable  return of
capital may reduce your tax basis in your Fund shares.

      This  information  is only a summary of certain  federal  tax  information
about your  investment.  More  information  is  contained  in the  Statement  of
Additional Information, and in addition you should consult with your tax adviser
about the effect of an investment in the Fund on your particular tax situation.

      The initial and  contingent  deferred  sales  charge rates and waivers for
Class A,  Class B and Class C shares  of the Fund  described  elsewhere  in this
Prospectus  are  modified  as  described  below  for those  shareholders  of (i)
Oppenheimer  Quest Value Fund,  Inc.,  Oppenheimer  Quest  Growth & Income Fund,
Oppenheimer Quest Opportunity Value Fund, Oppenheimer Quest Small Cap Value Fund
and  Oppenheimer  Quest  Global  Value Fund,  Inc. on November  24,  1995,  when
OppenheimerFunds,  Inc. became the investment  advisor to those funds,  and (ii)
Quest for Value U.S.  Government Income Fund, Quest for Value Investment Quality
Income  Fund,  Quest  for value  Global  Income  Fund,  Quest for Value New York
Tax-Exempt  Fund,  Quest for Value National  Tax-Exempt Fund and Quest for Value
California  Tax- Exempt Fund when those funds  merged into  various  Oppenheimer
funds on November  24,  1995.  The funds  listed  above are  referred to in this
Prospectus  as the  "Former  Quest for Value  Funds." The waivers of initial and
contingent  deferred sales charges described in this Appendix apply to shares of
the Fund (i) acquired by such  shareholder  pursuant to an exchange of shares of
one of the Oppenheimer funds that was one of the Former Quest for Value Funds or
(ii) purchased by such  shareholder  by exchange of shares of other  Oppenheimer
funds that were  acquired  pursuant to the merger of any of the Former Quest for
Value Funds into an Oppenheimer fund on November 24, 1995.
    

Class A Sales Charges

o Reduced  Class A Initial  Sales Charge  Rates for Certain  Former
Quest Shareholders

o  Purchases  by Groups and  Associations.  The  following  table sets forth the
initial  sales  charge  rates  for  Class  A  shares  purchased  by  members  of
"Associations"  formed for any purpose  other than the purchase of securities if

those  shares  are  subject  to the Class A  contingent  deferred  sales  charge
described on page __ of this
Prospectus.

   
      Purchases made under this  arrangement  qualify for the lower of the sales
charge rate in the table based on the number of members of an Association or the
sales charge rate that applies under the Rights of Accumulation  described above
in the Prospectus.  Individuals  who qualify under this  arrangement for reduced
sales charge rates as members of Associations also may purchase shares for their
individual  or custodial  accounts at these  reduced  sales charge  rates,  upon
request to the Fund's Distributor.

o Waiver of Class A Sales Charges for Certain Shareholders
    

Class A shares of the Fund purchased by the following  investors are not subject
to any Class A initial or contingent deferred sales
charges:

      o  Shareholders  of the Fund who were  shareholders  of the AMA  Family of
Funds on February  28, 1991 and who  acquired  shares of any of the Former Quest
for Value Funds by merger of a portfolio of the
AMA Family of Funds.
      o  Shareholders  of the Fund who  acquired  shares of any Former Quest for
Value Fund by merger of any of the portfolios of the Unified Funds.

o  Waiver  of  Class  A   Contingent   Deferred   Sales  Charge  in
Certain Transactions

Class A  shares  of the  Fund  purchased  by the  following  investors  who were
shareholders of any Former Quest for
Value Fund:

      o Investors who purchased  Class A shares from a dealer that is or was not
permitted  to receive a sales load or  redemption  fee imposed on a  shareholder
with whom that dealer has a fiduciary relationship under the Employee Retirement
Income Security Act of 1974 and regulations adopted under that law.

Class A,  Class B and  Class C  Contingent  Deferred  Sales  Charge
Waivers

o  Waivers  for  Redemptions  of  Shares  Purchased  Prior to March
6, 1995

In the following cases, the contingent  deferred sales charge will be waived for
redemptions  of Class A, Class B or Class C shares of the Fund  acquired  by the
merger of a Former  Quest for Value  Fund into the Fund or by  exchange  from an
Oppenheimer  fund that was a Former Quest for Value Fund or into which such fund
merged,  if those  shares were  purchased  prior to March 6, 1995 in  connection
with: (i)  withdrawals  under an automatic  withdrawal  plan holding only either
Class B or Class C shares if the  annual  withdrawal  does not exceed 10% of the
initial value of the account, and (ii) liquidation of a shareholder's account if
the  aggregate  net asset  value of shares  held in the account is less than the
required minimum value of such accounts.

o  Waivers  for  Redemptions  of  Shares   Purchased  on  or  After
March 6, 1995 but Prior to November 24, 1995.

In the following cases, the contingent  deferred sales charge will be waived for
redemptions  of Class A, Class B or Class C shares of the Fund  acquired  by the
merger of a Former  Quest for Value  Fund into the Fund or by  exchange  from an
Oppenheimer  fund that was a Former Quest For Value Fund or into which such fund
merged,  if those shares were  purchased on or after March 6, 1995, but prior to
November 24, 1995:  (1)  redemptions  following  the death or  disability of the
shareholder(s)  (as evidenced by a determination of total disability by the U.S.
Social Security  Administration);  (2) withdrawals under an automatic withdrawal
plan (but only for Class B or Class C shares)  where the annual  withdrawals  do
not exceed 10% of the initial  value of the account;  and (3)  liquidation  of a
shareholder's  account if the  aggregate  net asset  value of shares held in the
account is less than the required minimum account value. A shareholder's account
will be credited with the amount of any contingent deferred sales charge paid on
the  redemption of any Class A, Class B or Class C shares of the Fund  described
in this  section if within 90 days  after  that  redemption,  the  proceeds  are
invested in the same Class of shares in this Fund or another Oppenheimer fund.

ABOUT THE FUND

Investment Objective and Policies

   
Investment Policies and Strategies.The  investment objective and policies of the
Fund  are  described  in  the  Prospectus.   Set  forth  below  is  supplemental
information  about those  policies and the types of securities in which the Fund
may  invest,  as well as the  strategies  the Fund may use to try to achieve its
objective.  Certain  capitalized  terms  used in this  Statement  of  Additional
Information have the same meaning as those terms have in the Prospectus.
    

Municipal  Securities.  There  are  variations  in  the  security  of  Municipal
Securities, both within a particular classification and between classifications,
depending on numerous  factors.  The yields of Municipal  Securities  depend on,
among other things,  general conditions of the Municipal Securities market, size
of a  particular  offering,  the  maturity of the  obligation  and rating of the
issue.  The  market  value of  Municipal  Securities  will  vary as a result  of
changing  evaluations  of the  ability  of their  issuers to meet  interest  and
principal  payments,  as well as changes in the  interest  rates  payable on new
issues of Municipal Securities.

     o Municipal Bonds.  The principal  classifications  of long-term  municipal
bonds are "general obligation" and "revenue" or "industrial development" bonds.

           o General  Obligation  Bonds.  Issuers  of general  obligation  bonds
include states, counties, cities, towns, and regional districts. The proceeds of
these  obligations are used to fund a wide range of public  projects,  including
construction or improvement of schools,  highways and roads, and water and sewer
systems.  The basic  security  behind general  obligation  bonds is the issuer's
pledge  of its full  faith and  credit  and  taxing  power  for the  payment  of
principal  and  interest.  The taxes that can be levied for the  payment of debt
service  may be  limited  or  unlimited  as to the  rate or  amount  of  special
assessments.

           o  Revenue  Bonds.  The  principal  security  for a  revenue  bond is
generally  the  net  revenues  derived  from a  particular  facility,  group  of
facilities,  or,  in some  cases,  the  proceeds  of a  special  excise or other
specific  revenue source.  Revenue bonds are issued to finance a wide variety of
capital projects including:  electric,  gas, water and sewer systems;  highways,
bridges,  and tunnels;  port and airport facilities;  colleges and universities;
and hospitals. Although the principal security behind these bonds may vary, many
provide  additional  security in the form of a debt  service  reserve fund whose
money  may be used to make  principal  and  interest  payments  on the  issuer's
obligations.  Housing  finance  authorities  have  a  wide  range  of  security,
including   partially  or  fully  insured  mortgages,   rent  subsidized  and/or
collateralized  mortgages,  and/or the net revenues from housing or other public
projects.  Some  authorities  provide further  security in the form of a state's
ability (without obligation) to make up deficiencies in the debt service reserve
fund.

     o Industrial  Development  Bonds.  Industrial  development bonds, which are
considered  municipal  bonds if the interest paid is exempt from federal  income
tax, are issued by or on behalf of public  authorities to raise money to finance
various privately operated  facilities for business and manufacturing,  housing,
sports,  and  pollution  control.  These  bonds are also used to finance  public
facilities  such as airports,  mass transit  systems,  ports,  and parking.  The
payment of the principal  and interest on such bonds is dependent  solely on the
ability of the facility's user to meet its financial obligations and the pledge,
if any, of real and personal property so financed as security for such payment.

      o Municipal Notes.  Municipal  Securities having a maturity when issued of
less than one year are  generally  known as  municipal  notes.  Municipal  notes
generally are used to provide for short-term working capital needs and include:

           o Tax  Anticipation  Notes.  Tax  anticipation  notes  are  issued to
finance working capital needs of municipalities.  Generally,  they are issued in
anticipation  of various  seasonal tax revenue,  such as income,  sales,  use or
business taxes, and are payable from these specific future taxes.

           o Revenue  Anticipation Notes.  Revenue anticipation notes are issued
in  expectation of receipt of other types of revenue,  such as Federal  revenues
available under the Federal revenue sharing programs.

     o Bond Anticipation  Notes.  Bond anticipation  notes are issued to provide
interim financing until long-term financing can be arranged.  In most cases, the
long-term bonds then provide the money for the repayment of the notes.

     o  Construction  Loan  Notes.  Construction  loan notes are sold to provide
construction  financing.  After  successful  completion  and  acceptance,   many
projects receive permanent financing through the Federal Housing Administration.

       o  Tax-Exempt   Commercial  Paper.   Tax-exempt  commercial  paper  is  a
short-term  obligation  with a stated maturity of 365 days or less. It is issued
by state and local  governments  or their agencies to finance  seasonal  working
capital  needs  or  as  short-term  financing  in  anticipation  of  longer-term
financing.

       o Floating  Rate/Variable  Rate  Obligations.  Floating rate and variable
rate demand notes are tax-exempt obligations which may have a stated maturity in
excess of one year,  but may include  features that permit the holder to recover
the  principal  amount of the  underlying  security at specified  intervals  not
exceeding  one year and upon no more than 30 days'  notice.  The  issuer of such
notes normally has a corresponding right, after a given period, to prepay in its
discretion the outstanding  principal  amount of the note plus accrued  interest
upon a specified  number of days notice to the holder.  The  interest  rate on a
floating rate demand note is based on a stated prevailing market rate, such as a
bank's prime rate, the 90-day U.S.  Treasury Bill rate, or some other  standard,
and is adjusted automatically each time such rate is adjusted. The interest rate
on a variable rate demand note is also based on a stated  prevailing market rate
but is adjusted  automatically at specified  intervals of no more than one year.
Generally,  the  changes  in the  interest  rate on such  securities  reduce the
fluctuation in their market value.  As interest rates decrease or increase,  the
potential  for  capital  appreciation  or  depreciation  is less  than  that for
fixed-rate  obligations of the same maturity.  The Trust's  investment  adviser,
OppenheimerFunds,  Inc. (the "Manager"),  may determine that an unrated floating
rate or variable rate demand  obligation  meets the Fund's quality  standards by
reason of being backed by a letter of credit or guarantee  issued by a bank that
meets the Fund's quality standards.

      |X|  Inverse  Floaters  and Other  Derivative  Investments.  Some  inverse
floaters  have a feature known as an interest rate "cap" as part of the terms of
the investment. Investing in inverse floaters that have interest rate caps might
be part of a portfolio  strategy to try to maintain a high current yield for the
Fund when the Fund has invested in inverse  floaters that expose the Fund to the
risk of short-term  interest rate fluctuation.  Embedded caps hedge a portion of
the Fund's  exposure to rising  interest  rates.  When interest rates exceed the
pre-determined  rate,  the cap generates  additional  cash flows that offset the
decline in interest rates on the inverse  floater,  and the hedge is successful.
However,  the Fund bears the risk that if  interest  rates do not rise above the
pre-determined  rate, the cap (which is purchased for additional  cost) will not
provide additional cash flows and will expire worthless.

      |X|  Municipal  Lease  Obligations.  From time to time the Fund may invest
more than 5% of its net assets in municipal lease obligations, generally through
the  acquisition  of  certificates  of  participation,   that  the  Manager  has
determined  to be liquid under  guidelines  set by the Board of Trustees.  Those
guidelines  require the Manager to  evaluate:  (1) the  frequency  of trades and
price  quotations  for such  securities;  (2) the  number  of  dealers  or other
potential  buyers  willing  to  purchase  or  sell  such  securities;   (3)  the
availability  of  market-makers;  and (4) the  nature  of the  trades  for  such
securities. The Manager will also evaluate the likelihood of a continuing market
for such securities throughout the time they are held by the Fund and the credit
quality of the instrument.  Municipal  leases may take the form of a lease or an
installment purchase contract issued by a state or local government authority to
obtain  funds to acquire a wide variety of equipment  and  facilities.  Although
lease obligations do not constitute general  obligations of the municipality for
which  the  municipality's  taxing  power  is  pledged,  a lease  obligation  is
ordinarily backed by the municipality's  covenant to budget for, appropriate and
make the  payments  due under  the  lease  obligation.  However,  certain  lease
obligations   contain   "non-appropriation"   clauses  which  provide  that  the
municipality has no obligation to make lease or installment purchase payments in
future years unless money is  appropriated  for such purpose on a yearly  basis.
Projects financed with  certificates of participation  generally are not subject
to state  constitutional  debt limitations or other statutory  requirements that
may be applicable to Municipal Securities.  Payments by the public entity on the
obligation  underlying  the  certificates  are derived  from  available  revenue
sources;  such revenue may be diverted to the funding of other municipal service
projects. Payments of interest and/or principal with respect to the certificates
are  not  guaranteed  and  do  not  constitute  an  obligation  of  the  issuing
municipality or any of its political subdivisions.

      In addition to the risk of "non-appropriation," municipal lease securities
do not yet have a highly  developed market to provide the degree of liquidity of
conventional  municipal  bonds.  Municipal  leases,  like other  municipal  debt
obligations,  are subject to the risk of non-payment.  The ability of issuers of
municipal  leases to make timely lease  payments  may be  adversely  affected in
general  economic  downturns  and as  relative  governmental  cost  burdens  are
reallocated among federal,  state and local governmental units. Such non-payment
would  result  in a  reduction  of income  to the  Fund,  and could  result in a
reduction in the value of the municipal  lease  experiencing  non-payment  and a
potential decrease in the net asset value of the Fund.

      o Private Activity Municipal  Securities.  The Tax Reform Act of 1986 (the
"Tax Reform  Act")  reorganized,  as well as amended,  the rules  governing  tax
exemption  for interest on Municipal  Securities.  The Tax Reform Act  generally
does not  change  the tax  treatment  of bonds  issued to  finance  governmental
operations.  Thus,  interest on obligations issued by or on behalf of a state or
local  government,  the proceeds of which are used to finance the  operations of
such governments  (e.g.,  general  obligation bonds) continues to be tax-exempt.
However,  the Tax Reform Act  further  limited the use of  tax-exempt  bonds for
non-governmental  (private) purposes. More stringent restrictions were placed on
the use of proceeds of such bonds.  Interest on certain  private  activity bonds
(other than those specified as "qualified"  tax-exempt  private  activity bonds,
e.g.,  exempt facility bonds including  certain  industrial  development  bonds,
qualified mortgage bonds,  qualified Section 501(c)(3) bonds,  qualified student
loan bonds, etc.) is taxable under the revised rules.

      Interest on certain  private  activity  bonds issued after August 7, 1986,
which  continues  to be  tax-exempt  will be  treated as a tax  preference  item
subject  to the  alternative  minimum  tax  (discussed  below) to which  certain
taxpayers  are  subject.  Furthermore,  a  private  activity  bond  which  would
otherwise  be a  qualified  tax-exempt  private  activity  bond will not,  under
Internal Revenue Code Section 147(a),  be a qualified bond for any period during
which it is held by a person who is a "substantial user" of the facilities or by
a "related person" of such a substantial user. This "substantial user" provision
is  applicable   primarily  to  exempt  facility  bonds,   including  industrial
development  bonds.  The Fund may not be an appropriate  investment for entities
which are  "substantial  users" (or  persons  related  thereto)  of such  exempt
facilities,  and such  persons  should  consult  their own tax  advisers  before
purchasing  shares. A "substantial user" of such facilities is defined generally
as a "non-exempt person who regularly uses part of a facility" financed from the
proceeds  of exempt  facility  bonds.  Generally,  an  individual  will not be a
"related  person"  under the Internal  Revenue Code unless such  investor or the
investor's   immediate   family   (spouse,   brothers,   sisters  and  immediate
descendants)  own directly or indirectly in the aggregate more than 50% in value
of the equity of a corporation or partnership which is a "substantial user" of a
facility  financed  from the  proceeds of exempt  facility  bonds.  In addition,
limitations  as to the amount of  private  activity  bonds  which each state may
issue were revised  downward by the Tax Reform Act, which will reduce the supply
of such bonds. The value of the Fund's portfolio could be affected if there is a
reduction in the availability of such bonds.  That value may also be affected by
a 1988 U.S.  Supreme  Court  decision  upholding  the  constitutionality  of the
imposition  of a Federal  tax on the  interest  earned on  Municipal  Securities
issued in bearer form.

      A Municipal Security is treated as a taxable private activity bond under a
test for: (a) a trade or business use and  security  interest,  or (b) a private
loan restriction. Under the trade or business use and security interest test, an
obligation is a private activity bond if: (i) more than 10% of bond proceeds are
used for  private  business  purposes  and (ii)  10% or more of the  payment  of
principal or interest on the issue is directly or  indirectly  derived from such
private use or is secured by the privately used property or the payments related
to the use of the  property.  For  certain  types of  uses,  a 5%  threshold  is
substituted for this 10% threshold.  (The term "private  business use" means any
direct or indirect  use in a trade or business  carried on by an  individual  or
entity other than a state or municipal  governmental unit.) Under the test for a
private loan restriction,  the amount of bond proceeds which may be used to make
private  loans is limited to the lesser of 5% or $5.0  million of the  proceeds.
Thus, certain issues of Municipal  Securities could lose their tax-exempt status
retroactively  if the  issuer  fails  to  meet  certain  requirements  as to the
expenditure of the proceeds of that issue or use of the bond-financed  facility.
The Fund  makes no  independent  investigation  of the  issuers of such bonds or
their use of  proceeds.  Should the Fund hold a bond that  loses its  tax-exempt
status  retroactively,  there might be an  adjustment to the  tax-exempt  income
previously paid to shareholders.

      The  Federal  alternative  minimum  tax is  designed  to  ensure  that all
taxpayers pay some tax, even if their regular tax is zero.  This is accomplished
in part by including in taxable income certain tax preference  items in arriving
at  alternative  minimum  taxable  income.  The  Tax  Reform  Act,  which  makes
tax-exempt  interest from certain  private  activity bonds a tax preference item
for purposes of the  alternative  minimum tax on  individuals  and  corporations
specifically  states  that  any  exempt-interest  dividend  paid by a  regulated
investment  company will be treated as interest on a specific  private  activity
bond to the  extent of its  proportionate  share of the  interest  on such bonds
received by the  regulated  investment  company.  The Treasury is  authorized to
issue  regulations  implementing  the  provision.  The Fund  may hold  Municipal
Securities the interest on which (and thus a proportionate  share of the exempt-
interest dividends paid by the Fund) will be subject to the Federal  alternative
minimum tax on individuals and  corporations.  The Fund  anticipates  that under
normal  circumstances  it will not  purchase  any such  securities  in an amount
greater than 20% of the Fund's total assets.

   
      o Ratings of  Municipal  Securities.  Moody's , S&P's,  Fitch's and Duff &
Phelps' or other rating  organizations  ratings (see Appendix A) represent their
respective opinions of the quality of the Municipal Securities they undertake to
rate.  However,  such  ratings are general and  subjective  and are not absolute
standards of quality. Consequently, Municipal Securities with the same maturity,
coupon and rating may have different yields,  while Municipal  Securities of the
same  maturity  and  coupon  with  different  ratings  may have the same  yield.
Investment  in  lower-quality   securities  may  produce  a  higher  yield  than
securities rated in the higher rating categories described in the Prospectus (or
judged by the Manager to be of comparable  quality).  However, the added risk of
lower quality  securities  might not be consistent with a policy of preservation
of capital.
    

      o Financial  Guaranty Insurance  Company.  The portfolio  insurance policy
obtained  by the  Fund  was  issued  by  Financial  Guaranty  Insurance  Company
("Financial  Guaranty").  Financial Guaranty is a subsidiary of FGIC Corporation
(the "Corporation"),  a Delaware holding company. Financial Guaranty,  domiciled
in the State of New York,  commenced  its  business of providing  insurance  and
financial guaranties for a variety of investment  instruments in January,  1984.
The  Corporation  is a  wholly-owned  subsidiary  of  General  Electric  Capital
Corporation.  Neither the Corporation nor General Electric  Capital  Corporation
are obligated to pay the debts of or the claims against Financial Guaranty.

      Financial Guaranty,  in addition to providing insurance for the payment of
interest on and principal of municipal  bonds and notes held in unit  investment
trust  and  mutual  fund  portfolios,  provides  insurance  for new  issues  and
secondary  market  issues of  municipal  bonds and notes and for portions of new
issues and  secondary  market  issues of  municipal  bonds and notes.  Financial
Guaranty also provides credit  enhancements  for  asset-backed  securities,  and
mortgage-backed securities.

      Financial Guaranty is currently authorized to write insurance in 50 states
and the District of Columbia,  files  reports  with state  insurance  regulatory
agencies  and is  subject  to audit and  review by such  authorities.  Financial
Guaranty  is also  subject  to  regulation  by the  State of New York  Insurance
Department.  Such regulation,  however,  is no guarantee that Financial Guaranty
will be able to perform on its  commitments  or  contracts  of  insurance in the
event a claim should be made thereunder at some time in the future.

      The policy of insurance  obtained by the Fund from Financial  Guaranty and
the  agreement  and   negotiations  in  respect   thereof   represent  the  only
relationship  between  Financial  Guaranty  and  the  Fund.  Otherwise,  neither
Financial  Guaranty nor its parent,  FGIC Corporation,  or any affiliate thereof
has any significant relationship, direct or indirect, with the Fund.

   
      Under the provisions of the Portfolio Insurance Policy, Financial Guaranty
unconditionally  and  irrevocably  agrees  to  pay  to  CitiBank,  N.A.  or  its
successor,  as its agent (the "Fiscal  Agent") that portion of the  principal of
and interest on the  securities  which shall become due for payment but shall be
unpaid by reason of nonpayment by the issuer.  Financial Guaranty will make such
payments to the Fiscal Agent on the date such principal or interest  becomes due
for payment or on the business  day next  following  the day on which  Financial
Guaranty  shall have  received  notice of  nonpayment,  whichever is later.  The
Fiscal Agent will disburse to the Fund the face amount of principal and interest
which is then due for  payment  but is unpaid by  reason  of  nonpayment  by the
issuer but only upon  receipt by the Fiscal  Agent of (i) evidence of the Fund's
right to receive  payment of the  principal or interest due for payment and (ii)
evidence,  including any appropriate instruments of assignment,  that all of the
rights to payment of such principal or interest due for payment  thereupon shall
vest in Financial Guaranty. (The proceeds attributable to interest payments will
be tax-exempt.) Upon such a payment by the Fiscal Agent, Financial Guaranty will
be fully  subrogated to all of the Fund's rights under the defaulted  obligation
which includes the right of Financial Guaranty to obtain payment from the issuer
to the extent of amounts paid by Financial Guaranty to the Fund.
    
      o Additional  Information About Municipal  Securities.  From time to time,
proposals  have been  introduced  before  Congress to restrict or eliminate  the
Federal  income tax  exemption  for  interest on Municipal  Securities.  Similar
proposals may be introduced in the future. If such a proposal were enacted,  the
availability of Municipal Securities for investment by the Fund and the value of
the portfolio of the Fund would be affected. At such time, the Board of Trustees
of the Trust would  re-evaluate  the  investment  objectives and policies of the
Fund and possibly submit to shareholders  proposals for changes in the structure
of the Fund.

Other Investment Techniques and Strategies.

     o Hedging  With  Options  and Futures  Contracts.  The Fund may use hedging
instruments  for the  purposes  described  in the  Prospectus.  When  hedging to
attempt to protect against declines in the market value of the Fund's portfolio,
or to permit  the Fund to  retain  unrealized  gains in the  value of  portfolio
securities  which have  appreciated,  or to facilitate  selling  securities  for
investment  reasons,  the Fund may: (i) sell  Interest Rate Futures or Municipal
Bond Index Futures, (ii) buy puts on such Futures or securities,  or (iii) write
covered calls on securities held by it, Interest Rate Futures, or Municipal Bond
Index  Futures.  When  hedging to  establish a position  in the debt  securities
markets as a temporary substitute for the purchase of individual debt securities
the Fund may: (i) buy Interest Rate Futures or Municipal Bond Index Futures,  or
(ii) buy calls on such Futures or debt securities. Normally, the Fund would then
purchase the debt securities and terminate the hedging position.

     The Fund's  strategy of hedging with Futures and options on Futures will be
incidental to the Fund's investment activities in the underlying cash market. In
the future, the Fund may employ hedging  instruments and strategies that are not
presently contemplated but which may be developed, to the extent such investment
methods are consistent  with the Fund's  investment  objective,  and are legally
permissible and disclosed in the Prospectus.  Additional  information  about the
hedging instruments the Fund may use is provided below.

      o Writing  Covered  Calls.  As described in the  Prospectus,  the Fund may
write covered calls. When the Fund writes a call on an investment, it receives a
premium  and  agrees  to  sell  the  callable  investment  to a  purchaser  of a
corresponding  call during the call period (usually not more than 9 months) at a
fixed  exercise  price (which may differ from the market price of the underlying
investment)  regardless  of market  price  changes  during the call  period.  To
terminate  its  obligation  on a call it has  written,  the Fund may  purchase a
corresponding call in a "closing purchase transaction." A profit or loss will be
realized,  depending  upon  whether the net of the amount of option  transaction
costs and the premium  received on the call the Fund has written is more or less
than the price of the call the Fund subsequently purchased. A profit may also be
realized if the call lapses unexercised, because the Fund retains the underlying
investment and the premium  received.  Those profits are  considered  short-term
capital gains for Federal income tax purposes,  as are premiums on lapsed calls,
and when  distributed  by the Fund are taxable as ordinary  income.  If the Fund
could not effect a closing purchase  transaction due to the lack of a market, it
would  have to hold  the  callable  investment  until  the  call  lapsed  or was
exercised.  The Fund will not write covered call options in an amount  exceeding
20% of the value of its total assets.

      The Fund may also write calls on Futures without owning a futures contract
or deliverable  securities,  provided that at the time the call is written,  the
Fund covers the call by  segregating  in escrow an  equivalent  dollar  value of
deliverable  securities or liquid  assets.  The Fund will  segregate  additional
liquid  assets if the  value of the  escrowed  assets  drops  below  100% of the
current value of the Future. In no circumstances  would an exercise notice as to
a Future put the Fund in a short futures position.

      The Fund's Custodian, or a securities depository acting for the Custodian,
will act as the Fund's  escrow  agent,  through  the  facilities  of the Options
Clearing  Corporation  ("OCC"),  as to the  investments  on  which  the Fund has
written options that are traded on exchanges,  or as to other acceptable  escrow
securities,  so that no margin  will be  required  from the Fund for such option
transactions.  OCC will release the securities covering a call on the expiration
of the call or when the Fund enters into a closing  purchase  transaction.  Call
writing affects the Fund's turnover rate and the brokerage  commissions it pays.
Commissions,  normally  higher  than on  general  securities  transactions,  are
payable on writing or purchasing a call.

      o  Interest  Rate  Futures.  The Fund may buy and sell  futures  contracts
relating to interest rates  ("Interest Rate Futures") and municipal bond indices
("Municipal Bond Index  Futures").  An Interest Rate Future obligates the seller
to deliver  and the  purchaser  to take a specific  type of debt  security  at a
specific future date for a fixed price to settle the futures transaction,  or to
enter into an offsetting contract. No monetary amount is paid or received by the
Fund on the purchase of an Interest Rate Future.  The Fund may  concurrently buy
and sell Futures  contracts in an attempt to benefit from any  outperformance of
the  Future  purchased  relative  to the  performance  of the Future  sold.  For
example,  the Fund might buy Municipal Bond Futures and sell U.S.  Treasury Bond
Futures  (a type of  Interest  Rate  Future).  This  type of  transaction  would
generally be profitable to the Fund if municipal bonds outperform U.S.  Treasury
bonds after duration has been considered.

     Duration is a volatility  measure  that refers to the  expected  percentage
change in the value of a bond resulting from a change in general  interest rates
(measured  by each 1%  change  in the rates on U.S.  Treasury  securities).  For
example,  if a bond has an effective  duration of three years,  a 1% increase in
general  interest rates would be expected to cause the bond to decline about 3%.
Risks of this type of  Futures  transaction,  using  the  example  above,  would
include (1) outperformance of U.S.  Treasuries relative to municipal bonds, on a
duration- adjusted basis, and (2) duration mismatch,  with duration of municipal
bonds relative to U.S. Treasuries being greater than anticipated.

      Upon  entering  into a Futures  transaction,  the Fund will be required to
deposit an initial margin  payment,  in cash or U.S.  Treasury  bills,  with the
futures commission merchant (the "futures broker"). Initial margin payments will
be deposited with the Fund's  Custodian in an account  registered in the futures
broker's name; however,  the futures broker can gain access to that account only
under certain specified conditions.  As the Future is marked to market (that is,
its value on the  Fund's  books is  changed)  to  reflect  changes in its market
value,  subsequent margin payments,  called variation margin, will be paid to or
by the futures broker on a daily basis.

     At any time prior to the  expiration  of the Future,  the Fund may elect to
close out its  position  by taking an opposite  position,  at which time a final
determination  of variation margin is made and additional cash is required to be
paid by or released to the Fund.  Any gain or loss is then  realized by the Fund
on the Future for tax  purposes.  Although  Interest  Rate  Futures call for the
delivery of a specific debt security, in most cases the settlement obligation is
fulfilled without such delivery by entering into an offsetting transaction.  All
Futures  transactions  are effected through a clearing house associated with the
exchange on which the contracts are traded.

      o Municipal Bond Index Futures.  A "municipal bond index" assigns relative
values to the municipal  bonds  included in that index,  and is used to serve as
the basis for trading long-term municipal bond Futures contracts. Municipal Bond
Index  Futures are similar to Interest  Rate Futures  except that  settlement is
made in cash.  The  obligation  under such  contracts  may also be  satisfied by
entering into an offsetting contract to close out the futures position. Net gain
or loss on options on such  Municipal  Bond Index  Futures  depends on the price
movements of the securities included in the index. The strategies which the Fund
employs  regarding  Municipal Bond Index Futures are similar to those  described
above with regard to Interest Rate Futures.

      o Interest Rate Swap  Transactions.  Swap agreements  entail both interest
rate risk and credit risk.  There is a risk that, based on movements of interest
rates in the future,  the payments made by the Fund under a swap  agreement will
have been  greater  than those  received  by it.  Credit  risk  arises  from the
possibility  that the  counterparty  will  default.  If the  counterparty  to an
interest rate swap  defaults,  the Fund's loss will consist of the net amount of
contractual  interest  payments that the Fund has not yet received.  The Manager
will monitor the  creditworthiness of counterparties to the Fund's interest rate
swap   transactions  on  an  ongoing  basis.  The  Fund  will  enter  into  swap
transactions  with  appropriate   counterparties   pursuant  to  master  netting
agreements.

      A master netting  agreement  provides that all swaps done between the Fund
and that  counterparty  under the master agreement shall be regarded as parts of
an integral  agreement.  If on any date amounts are payable in the same currency
in respect of one or more swap transactions, the net amount payable on that date
in that currency shall be paid. In addition,  the master  netting  agreement may
provide that if one party defaults  generally or on one swap,  the  counterparty
may terminate the swaps with that party.  Under such  agreements,  if there is a
default resulting in a loss to one party, the measure of that party's damages is
calculated by reference to the average cost of a  replacement  swap with respect
to each swap (i.e., the  mark-to-market  value at the time of the termination of
each swap). The gains and losses on all swaps are then netted, and the result is
the counterparty's gain or loss on termination. The termination of all swaps and
the  netting of gains and losses on  termination  is  generally  referred  to as
"aggregation."  The Fund will not invest more than 25% of its assets in interest
rate swap transactions and only on securities it owns.

     o Purchasing Puts and Calls. The Fund may purchase calls to protect against
the possibility that the Fund's portfolio will not participate in an anticipated
rise in the securities  market.  When the Fund purchases a call (other than in a
closing  purchase  transaction),  it pays a premium  and,  except as to calls on
Municipal  Bond Index Futures,  has the right to buy the  underlying  investment
from a seller of a  corresponding  call on the same  investment  during the call
period at a fixed exercise  price.  In purchasing a call, the Fund benefits only
if the call is sold at a profit or if, during the call period,  the market price
of the  underlying  investment  is above the sum of the call price,  transaction
costs,  and the  premium  paid,  and the call is  exercised.  If the call is not
exercised or sold (whether or not at a profit),  it will become worthless at its
expiration  date and the Fund will  lose its  premium  payment  and the right to
purchase  the  underlying  investment.  When  the  Fund  purchases  a call  on a
municipal bond index,  Municipal  Bond Index Future or Interest Rate Future,  it
pays a  premium,  but  settlement  is in cash  rather  than by  delivery  of the
underlying investment to the Fund.

      When the Fund purchases a put, it pays a premium and, except as to puts on
municipal  bond indices,  has the right to sell the  underlying  investment to a
seller of a corresponding  put on the same investment during the put period at a
fixed exercise price.  Buying a put on a debt security,  Interest Rate Future or
Municipal Bond Index Future the Fund owns (a "protective  put") enables the Fund
to  attempt  to protect  itself  during the put period  against a decline in the
value of the  underlying  investment  below the  exercise  price by selling  the
underlying  investment at the exercise price to a seller of a corresponding put.
If the  market  price of the  underlying  investment  is  equal to or above  the
exercise price and as a result the put is not exercised or resold,  the put will
become  worthless at its expiration  and the Fund will lose the premium  payment
and the right to sell the underlying  investment.  However,  the put may be sold
prior to expiration (whether or not at a profit).

      An option  position  may be  closed  out only on a market  which  provides
trading for options of the same series,  and there is no assurance that a liquid
secondary  market  will  exist for any  particular  option.  The  Fund's  option
activities may affect its portfolio turnover rate and brokerage commissions. The
exercise  of  calls  written  by the  Fund may  cause  the Fund to sell  related
portfolio  securities,  thus  increasing  its turnover rate. The exercise by the
Fund of puts on  securities  will  cause  the  sale of  underlying  investments,
increasing  portfolio turnover.  Although the decision whether to exercise a put
it holds is within the  Fund's  control,  holding a put might  cause the Fund to
sell the related  investments for reasons that would not exist in the absence of
the put. The Fund will pay a brokerage  commission  each time it buys or sells a
call, put or an underlying  investment in connection  with the exercise of a put
or call.  Those  commissions  may be  higher  than the  commissions  for  direct
purchases or sales of the underlying investments.

      Premiums paid for options are small in relation to the market value of the
underlying  investments  and,  consequently,  put and call  options  offer large
amounts of leverage.  The leverage offered by trading in options could result in
the Fund's net asset value being more  sensitive  to changes in the value of the
underlying investments.

      o  Regulatory  Aspects of Hedging  Instruments.  The Fund is  required  to
operate within certain  guidelines and  restrictions  with respect to its use of
Futures and options on Futures  established  by the  Commodity  Futures  Trading
Commission  ("CFTC").  In particular the Fund is exempted from registration with
the  CFTC  as a  "commodity  pool  operator"  if  the  Fund  complies  with  the
requirements  of Rule 4.5  adopted  by the  CFTC.  The Rule  does not  limit the
percentage of the Fund's assets that may be used for Futures  margin and related
options premiums for a bona fide hedging position.  However,  under the Rule the
Fund must limit its aggregate initial futures margin and related option premiums
to no more than 5% of the Fund's net assets for hedging  strategies that are not
considered bona fide hedging strategies under the Rule. Under the Rule, the Fund
also must use short Futures and Futures options  positions solely for "bona fide
hedging purposes" within the meaning and intent of the applicable  provisions of
the Commodity Exchange Act.

      Transactions in options by the Fund are subject to limitations established
by option exchanges  governing the maximum number of options that may be written
or held by a single investor or group of investors acting in concert, regardless
of whether  the  options  were  written or  purchased  on the same or  different
exchanges or are held in one or more  accounts or through one or more  different
exchanges or through one or more  brokers.  Thus the number of options which the
Fund may  write or hold may be  affected  by  options  written  or held by other
entities,  including other  investment  companies having the same adviser as the
Fund (or an adviser that is an affiliate of the Fund's  adviser).  The exchanges
also impose position limits on Futures  transactions.  An exchange may order the
liquidation of positions found to be in violation of those limits and may impose
certain other sanctions.

      Due to  requirements  under  the  Investment  Company  Act,  when the Fund
purchases an Interest Rate Future or Municipal Bond Index Future,  the Fund will
maintain,  in a  segregated  account or  accounts  with its  Custodian,  cash or
readily-marketable,  short-term  (maturing in one year or less) debt instruments
in an amount equal to the market value of the securities underlying such Future,
less the margin deposit applicable to it.

   
      o Tax Aspects of Covered Calls and Hedging  Instruments.  The Fund intends
to qualify as a "regulated  investment  company" under the Internal Revenue Code
(although it reserves the right not to qualify).  That qualification enables the
Fund to "pass  through" its income and realized  capital  gains to  shareholders
without having to pay tax on them. This avoids a "double tax" on that income and
capital gains,  since  shareholders  normally will be taxed on the dividends and
capital gains they receive from the Fund (unless the Fund's shares are held in a
retirement account or the shareholder is otherwise exempt from tax).
    

     o Risks of Hedging  With  Options and  Futures.  An option  position may be
closed out only on a market that provides  secondary  trading for options of the
same series, and there is no assurance that a liquid secondary market will exist
for any particular option. In addition to the risks associated with hedging that
are  discussed  in the  Prospectus  and  above,  there is a risk in using  short
hedging by selling  Interest Rate Futures or Municipal Bond Index  Futures.  The
risk is that the prices of such Futures or the  applicable  index will correlate
imperfectly  with the behavior of the cash (i.e.,  market  value)  prices of the
Fund's  securities.  The ordinary spreads between prices in the cash and futures
markets are subject to  distortions,  due to differences in the natures of those
markets.  First,  all  participants in the futures markets are subject to margin
deposit and  maintenance  requirements.  Rather than meeting  additional  margin
deposit  requirements,   investors  may  close  out  futures  contracts  through
offsetting  transactions which could distort the normal relationship between the
cash and futures markets.  Second,  the liquidity of the futures markets depends
on  participants  entering into  offsetting  transactions  rather than making or
taking  delivery.  To the extent  participants  decide to make or take delivery,
liquidity in the futures  markets could be reduced,  thus producing  distortion.
Third,  from the point of view of speculators,  the deposit  requirements in the
futures  markets are less onerous  than margin  requirements  in the  securities
markets.  Therefore,  increased  participation  by  speculators  in the  futures
markets may cause temporary price distortions.

      The risk of  imperfect  correlation  increases as the  composition  of the
Fund's portfolio diverges from the securities  included in the applicable index.
To  compensate  for the imperfect  correlation  of movements in the price of the
equity  securities  being  hedged  and  movements  in the  price of the  hedging
instruments,  the Fund may use hedging  instruments  in a greater  dollar amount
than the  dollar  amount of equity  securities  being  hedged if the  historical
volatility  of the prices of the debt  securities  being hedged is more than the
historical  volatility of the applicable  index. It is also possible that if the
Fund has used hedging  instruments in a short hedge,  the market may advance and
the value of debt securities held in the Fund's  portfolio may decline.  If that
occurred,  the  Fund  would  lose  money  on the  hedging  instruments  and also
experience a decline in value in its portfolio securities.  However,  while this
could  occur for a very brief  period or to a very small  degree,  over time the
value of a  diversified  portfolio of debt  securities  will tend to move in the
same direction as the indices upon which the hedging instruments are based.

     If the Fund uses  hedging  instruments  to establish a position in the debt
markets as a temporary substitute for the purchase of individual debt securities
(long hedging) by buying  Interest Rate Futures or Municipal Bond Futures and/or
calls on such Futures,  on securities or on stock  indices,  it is possible that
the  market  may  decline.  If the Fund  then  concludes  not to  invest in such
securities  at that time  because of  concerns as to a possible  further  market
decline  or for  other  reasons,  the Fund will  realize  a loss on the  hedging
instruments  that  is not  offset  by a  reduction  in  the  price  of the  debt
securities purchased.

   
      o  When-Issued  and  Delayed  Delivery  Transactions.  As  stated  in  the
Prospectus,  the Fund may invest in Municipal  Securities on a "when-issued"  or
"delayed  delivery" basis.  Payment for and delivery of the securities  normally
occurs within six months of the purchase of municipal bonds and notes.  However,
the Fund may, from time to time, purchase municipal  securities whose settlement
extends beyond six months and possibly as long as two years or more beyond trade
date.  The purchase  price and yield are fixed at the time the buyer enters into
the commitment. During the period between purchase and settlement, no payment is
made by the Fund to the  issuer  and no  interest  accrues to the Fund from this
investment.  However,  the Fund intends to be as fully  invested as possible and
will not invest in when- issued securities if its income or net asset value will
be materially  adversely affected.  At the time the Fund makes the commitment to
purchase  a  Municipal  Security  on a  when-issued  basis,  it will  record the
transaction  on its books and reflect the value of the  security in  determining
its net asset  value.  It will also  segregate  cash or other  liquid  Municipal
Securities  equal in value to the  commitment  for the  when-issued  securities.
While  when-issued  securities  may be sold prior to settlement  date,  the Fund
intends to acquire the securities  upon  settlement  unless a prior sale appears
desirable for investment  reasons.  There is a risk that the yield  available in
the market when  delivery  occurs may be higher  than the yield on the  security
acquired.
    

     o  Repurchase  Agreements.  The  Fund may  acquire  securities  subject  to
repurchase agreements for liquidity purposes to meet anticipated redemptions, or
pending the investment of the proceeds from sales of Fund shares, or pending the
settlement of purchases of portfolio securities.

      In a  repurchase  transaction,  the Fund  acquires  a security  from,  and
simultaneously resells it to, an approved vendor. An "approved vendor" is a U.S.
commercial bank or the U.S.  branch of a foreign bank or a  broker-dealer  which
has been designated a primary dealer in government  securities,  which must meet
credit  requirements set by the Trust's Board of Trustees from time to time. The
resale  price  exceeds  the  purchase  price  by  an  amount  that  reflects  an
agreed-upon  interest rate  effective for the period during which the repurchase
agreement is in effect.  The majority of these transactions run from day to day,
and delivery pursuant to the resale typically will occur within one to five days
of  the  purchase.  Repurchase  agreements  are  considered  "loans"  under  the
Investment Company Act,  collateralized by the underlying  security.  The Fund's
repurchase  agreements require that at all times while the repurchase  agreement
is in effect,  the value of the  collateral  must equal or exceed the repurchase
price to fully collateralize the repayment obligation. Additionally, the Manager
will  impose  creditworthiness  requirements  to  confirm  that  the  vendor  is
financially sound and will continuously monitor the collateral's value.

      o  Loans  of  Portfolio  Securities.  The  Fund  may  lend  its  portfolio
securities  subject  to  the  restrictions  stated  in  the  Prospectus.   Under
applicable  regulatory  requirements  (which are  subject to  change),  the loan
collateral  on each  business  day must at least  equal the value of the  loaned
securities and must consist of cash, bank letters of credit or securities of the
U.S.  Government  (or its agencies or  instrumentalities).  To be  acceptable as
collateral,  letters of credit must  obligate a bank to pay amounts  demanded by
the Fund if the demand meets the terms of the letter. Such terms and the issuing
bank  must be  satisfactory  to the  Fund.  When it lends  securities,  the Fund
receives  amounts  equal to the dividends or interest on loaned  securities  and
also  receives  one or  more  of (a)  negotiated  loan  fees,  (b)  interest  on
securities  used as collateral,  and (c) interest on short-term  debt securities
purchased with such loan collateral.  Either type of interest may be shared with
the  borrower.  The  Fund  may  also  pay  reasonable  finder's,  custodian  and
administrative  fees. The terms of the Fund's loans must meet  applicable  tests
under the Internal  Revenue  Code and must permit the Fund to  reacquire  loaned
securities on five days' notice or in time to vote on any important matter.


Other Investment Restrictions

      The Fund's most significant  investment  restrictions are set forth in the
Prospectus.  There are  additional  investment  restrictions  that the Fund must
follow that are also fundamental  policies.  Fundamental policies and the Fund's
investment  objective  cannot be changed without the vote of a "majority" of the
Fund's outstanding  voting securities.  Under the Investment Company Act, such a
"majority"  vote of the Fund is defined as the vote of the holders of the lesser
of:  (i) 67% or more of the  shares  present  or  represented  by  proxy at such
meeting,  if the holders of more than 50% of the outstanding shares are present,
or (ii) more than 50% of the outstanding shares of the Fund.

      Under these additional restrictions, the Fund cannot:

      (1)  invest  in real  estate,  but this  shall not  prevent  the Fund from
      investing in Municipal  Instruments  or other  permissible  securities  or
      instruments secured by real estate or interests thereon;

      (2) invest in  interests  in oil,  gas, or other  mineral  exploration  or
      development programs;

      (3) purchase  securities,  or other instruments,  on margin;  however, the
      Fund may  invest in  options,  futures,  options on  futures  and  similar
      instruments  and may make  margin  deposits  and  payments  in  connection
      therewith;

      (4) make short sales of securities;

      (5) underwrite  securities  except to the extent the Fund may be deemed to
      be an  underwriter in connection  with the sale of securities  held in its
      portfolio;

      (6) invest in securities of other investment companies, except as they may
      be acquired as part of a merger, consolidation or other acquisition;

      (7) make investments for the purpose of exercising  control of management;
      or

      (8) purchase  securities  of any issuer if, to the  knowledge of the Fund,
      its officers  and  trustees and officers and  directors of the Manager who
      individually  own more than 5% of the  securities of such issuer  together
      own beneficially more than 5% of such issuer's outstanding securities.

      As a matter of  non-fundamental  policy,  the Fund shall not  purchase  or
retain  securities  if as a result the Fund would have more than 5% of its total
assets  invested in securities of private  issuers  having a record of less than
three years'  continuous  operation  (such  period may include the  operation of
predecessor companies or enterprises) or in industrial  development bonds if the
private entity on whose credit the security is based, directly or indirectly, is
less than three years old (including predecessors), unless the security is rated
by a  nationally-recognized  rating  service;  or invest in common  stock or any
warrants related thereto.

   
      For  purposes  of the Fund's  policy not to  concentrate  described  under
"Other  Investment  Restrictions"  in the  Prospectus,  the Fund has adopted the
industry classifications set forth in Appendix C to this Statement of Additional
Information. This is not a fundamental policy.
    

How the Fund Is Managed

Organization and History. Oppenheimer Municipal Fund is a Massachusetts business
trust and is composed of two series. The Fund is one of the series. The Trust is
not  required to hold,  and does not plan to hold,  regular  annual  meetings of
shareholders. The Trust and/or Fund will hold meetings when required to do so by
the  Investment  Company  Act or other  applicable  law,  or when a  shareholder
meeting is called by the  Trustees or upon proper  request of the  shareholders.
Shareholders  have  the  right,  upon  the  declaration  in  writing  or vote of
two-thirds  of the  outstanding  shares of the Trust,  to remove a Trustee.  The
Trustees will call a meeting of shareholders to vote on the removal of a Trustee
upon the written request of the record holders of 10% of the outstanding  shares
of the Trust.  In addition,  if the Trustees  receive a request from at least 10
shareholders (who have been shareholders for at least six months) holding shares
of the Trust  valued at $25,000  or more or  holding at least 1% of the  Trust's
outstanding  shares,  whichever is less,  stating that they wish to  communicate
with other  shareholders to request a meeting to remove a Trustee,  the Trustees
will then either make the Trust's  shareholder  list available to the applicants
or  mail  their  communication  to all  other  shareholders  at the  applicants'
expense,  or the Trustees may take such other action as set forth under  Section
16(c) of the Investment Company Act.

   
      Each share of the Fund  represents  an  interest  in the Fund equal to the
interest  of each other  share of the same class and  entitle  the holder to one
vote per  share  (and a  fractional  vote for a  fractional  share)  on  matters
submitted to their vote at shareholders' meetings.
    

   
     Shareholders of the Trust vote together in the aggregate on certain matters
at shareholders'  meetings, such as the election of Trustees and ratification of
appointment of auditors for the Trust.  Shareholders  of a particular  series or
class vote  separately  on  proposals  which  affect that  series or class,  and
shareholders  of a series or class which is not  affected by that matter are not
entitled  to vote on the  proposal.  Shareholders  of a  class  vote on  certain
amendments to the  Distribution  and/or Service Plans if the  amendments  affect
that class.
    

     The Trustees are authorized to create new series and classes of series. The
Trustees may  reclassify  unissued  shares of the Trust or its series or classes
into  additional  series or classes of shares.  The  Trustees may also divide or
combine the shares of a class into a greater or lesser number of shares provided
that the  proportionate  beneficial  interest of a  shareholder  in the Fund and
Trust is not changed.  Shares do not have cumulative voting rights or preemptive
or subscription rights. Shares may be voted in person or by proxy.

      The Declaration of Trust contains an express  disclaimer of shareholder or
Trustee liability for the Fund's  obligations,  and provides for indemnification
and  reimbursement  of expenses  out of its property  for any  shareholder  held
personally  liable for its  obligations.  The Declaration of Trust also provides
that the Fund shall, upon request,  assume the defense of any claim made against
any  shareholder  for any act or obligation of the Fund and satisfy any judgment
thereon. Thus, while Massachusetts law permits a shareholder of a business trust
(such as the Fund) to be held  personally  liable as a "partner"  under  certain
circumstances,  the  risk  of a Fund  shareholder  incurring  financial  loss on
account  of  shareholder   liability  is  limited  to  the   relatively   remote
circumstances  in  which  the  Fund  would be  unable  to meet  its  obligations
described  above.  Any person doing business with the Trust, and any shareholder
of the Trust,  agrees under the Trust's  Declaration  of Trust to look solely to
the assets of the Trust for  satisfaction of any claim or demand which may arise
out of any  dealings  with the Trust,  and the  Trustees  shall have no personal
liability to any such person, to the extent permitted by law.

1  For the 1997 calendar year.
2  Committee positions effective July 1, 1997.
3  Prior to July 1, 1997, Messrs.  Conrad and Kirchner were also
   members of the Audit and Review Committee.

      o Deferred Compensation Plan. The Board of Trustees has adopted a Deferred
Compensation Plan for  disinterested  Trustees that enables Trustees to elect to
defer  receipt  of all or a portion  of the  annual  fees they are  entitled  to
receive from the Fund. Under the plan, the compensation deferred by a Trustee is
periodically 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 Fund's assets, liabilities or net income per share. The plan will not
obligate the Fund to retain the services of any Trustee or to pay any particular
amount  of  compensation  to any  Trustee.  Pursuant  to an Order  issued by the
Securities and Exchange  Commission,  the Fund may, without shareholder approval
and  notwithstanding  its  fundamental  policy  restricting  investment in other
open-end  investment  companies,  as described  above on page 13,  invest in the
funds  selected  by the  Trustee  under  the plan  for the  limited  purpose  of
determining the value of the Trustee's deferred fee account.

      o Major  Shareholders.  As of December 31, 1997, no person owned of record
or was known by the Trust to own  beneficially  5% or more of the  shares of the
Trust as a whole or either class of the Fund's  outstanding  Class A and Class B
shares.  As of that date,  the only  shareholders  which owned of record or were
known by the Fund to own  beneficially  5% or more of the Fund's  Class C shares
were Merrill Lynch Pierce Fenner & Smith for the Sole Benefit of its  Customers,
4800 Deer Lake Drive E. Fl. 3, Jacksonville,  FL 32246-6484, who owned of record
39,020.000 Class C shares (representing 22.56% of the Fund's outstanding Class C
shares); Margie H. Madak Trust, 8619 W. Sunnyside Ave.,     
   
Chicago,  IL  60656-4149,   who  owned  of  record  19,285.502  Class  C  shares
(representing  11.15% of the Fund's  outstanding  Class C shares);  B&J Inc., 15
Country Club Rd. #C,  Honolulu,  HI  96817-1408  who owned of record  12,133.371
Class C shares  (representing  7.13% of the Fund's  outstanding  Class C shares)
Donaldson Lufkin Jenrette  Securities  Corporation,  Inc., P.O. Box 2052, Jersey
City, NJ 07303- 9978, who owned of record 581 Class C shares (representing 6.69%
of the Fund's  outstanding  Class C shares) and NFSC FBO Charles & Margaret Gash
Co. Trust, 1137 Damico, Chicago Heights, IL 60411, who owned of record 9,703.826
Class C shares (representing 5.61% of the Fund's outstanding Class C shares).

     The Manager and Its Affiliates.  The Manager is wholly-owned by Oppenheimer
Acquisition Corp. ("OAC"), a holding company controlled by Massachusetts  Mutual
Life  Insurance  Company.  OAC is also owned in part by certain of the Manager's
directors  and officers,  some of whom also serve as officers of the Trust,  and
three of whom (Ms. Macaskill,  Mr. Swain and Mr. Bowen) serve as Trustees of the
Trust.
    

      The Manager  and the Fund have a Code of Ethics.  It is designed to detect
and prevent improper personal trading by certain employees,  including portfolio
managers,  that would  compete with or take  advantage  of the Fund's  portfolio
transactions.  Compliance  with the Code of Ethics is  carefully  monitored  and
strictly enforced by the Manager.

   
      |X|  Portfolio  Management.  The  portfolio  manager  of the Fund is Caryn
Halbrecht,  who is principally  responsible for the day-to-day management of the
Fund's portfolio. The background of Ms. Halbrecht is described in the Prospectus
under "Portfolio Manager." Other members of the Manager's fixed-income portfolio
department,   particularly  portfolio  analysts,  traders  and  other  portfolio
managers having broad experience with domestic and international  government and
corporate  fixed-income  securities,  provide the Fund's portfolio managers with
support in managing the Fund's portfolio.
    

      o The Investment  Advisory  Agreement.  The Investment  Advisory Agreement
between the Manager and the Trust on behalf of the Fund requires the Manager, at
its expense,  to provide the Fund with  adequate  office space,  facilities  and
equipment and to provide and supervise the activities of all  administrative and
clerical  personnel required to provide effective  corporate  administration for
the Fund,  including the  compilation and maintenance of records with respect to
its  operations,  the  preparation  and  filing of  specified  reports,  and the
composition of proxy materials and registration statements for continuous public
sale of shares of the Fund.

      Expenses  not  expressly  assumed  by the  Manager  under  the  Investment
Advisory  Agreement  or by  the  Distributor  under  the  General  Distributor's
Agreement are paid by the Fund. Expenses with respect to the Trust's two series,
including  the  Fund,  are  allocated  in  proportion  to the net  assets of the
respective  funds except where  allocations  of direct  expenses  could be made.
Certain expenses are further  allocated to certain classes of shares of a series
as  explained  in the  Prospectus  and  under  "How to Buy  Shares"  below.  The
Investment  Advisory  Agreement lists examples of expenses paid by the Fund, the
major categories of which relate to interest, taxes, brokerage commissions, fees
to certain  Trustees,  legal and audit  expenses,  transfer  agent and custodian
expenses,  share issuance costs,  certain  printing and  registration  costs and
non-recurring expenses, including litigation costs.

   
      Under the Investment  Advisory Agreement , the Manager had agreed that the
Fund's total expenses in any fiscal year (including the investment  advisory fee
but  exclusive of taxes,  interest,  brokerage  commissions,  distribution  plan
payments and any extraordinary  non-recurring  expenses,  including  litigation)
would not exceed the most stringent state  regulatory  limitation  applicable to
the Fund. Due to changes in federal  securities laws, such state  regulations no
longer apply . During the Fund's last fiscal year,  the Fund's  expenses did not
exceed the most stringent state regulatory limit and the expense  limitation was
not invoked.

      The  advisory   agreement   provides   that  in  the  absence  of  willful
misfeasance,  bad faith or gross negligence in the performance of its duties, or
reckless disregard for its obligations and duties under the advisory  agreement,
the  Manager  is not liable for any loss  resulting  from a good faith  error or
omission on its part with respect to any of its duties thereunder.  The advisory
agreement permits the Manager to act as investment adviser for any other person,
firm or corporation . Pursuant to a non-exclusive license agreement, the Manager
permits the Trust and the Fund to use the name  "Oppenheimer" in connection with
other investment companies for which it may act as investment adviser or general
distributor.  If the Manager  shall no longer act as  investment  adviser to the
Fund,  the right of the Fund to use the name  "Oppenheimer"  as part of its name
may be withdrawn.  During the Fund's fiscal year ended  September 30, 1997,  the
management fees were $471,703.

     o The  Distributor.  Under its  General  Distributor's  Agreement  with the
Trust, the Distributor,  OppenheimerFunds  Distributor,  Inc. acts as the Fund's
principal  underwriter in the continuous  public offering of the Fund's Class A,
Class B and Class C shares but is not  obligated  to sell a  specific  number of
shares.  Expenses normally  attributable to sales,  excluding payments under the
Distribution  and  Service  Plans  but  including  advertising  and the  cost of
printing  and  mailing  prospectuses  (other  than those  furnished  to existing
shareholders) are borne by the Distributor.
    

   
      During the Fund's  fiscal years ended  September  30, 1995 , 1996 and 1997
the aggregate sales charges on sales of the Fund's Class A shares was $153,803 ,
$180,294 and $164,201,  respectively, of which the Distributor and an affiliated
broker-dealer  retained in the aggregate $43,162 , $41,094 and $35,272, in those
respective  years.  During the Fund fiscal year ended  September  30, 1997,  the
contingent  deferred sales charge collected on the Fund's Class B shares totaled
$53,881, all of which the Distributor retained. For additional information about
distribution  of  the  Fund's  shares  and  the  expenses  connected  with  such
activities,  please refer to  "Distribution  and Service  Plans,"  below.  Sales
charges  advanced to  broker/dealers  by the  Distributor on sales of the Fund's
Class B shares during the fiscal year ended September 30, 1997 were $222,466, of
which $2,152 was paid to an affiliate.  Sales charges advanced to broker/dealers
by the  Distributor on sales of the Fund's Class C shares during the fiscal year
ended September 30, 1997 were $18,115, of which $1,686 was paid to an affiliate.
    

     o The Transfer Agent. The Fund's Transfer Agent, OppenheimerFunds Services,
a division of the Manager, is responsible for maintaining the Fund's shareholder
registry and shareholder  accounting records, and for shareholder  servicing and
administrative functions.

Brokerage Policies of the Fund

Brokerage Provisions of the Investment Advisory Agreement.  One of the duties of
the Manager under the Investment  Advisory Agreement is to arrange the portfolio
transactions for the Fund. The Investment Advisory Agreement contains provisions
relating to the  employment of  broker-dealers  ("brokers") to effect the Fund's
portfolio transactions. In doing so, the Manager is authorized by the Investment
Advisory  Agreement  to  employ  such  broker-dealers,   including  "affiliated"
brokers,  as that term is defined in the Investment  Company Act, as may, in its
best judgment based on all relevant factors, implement the policy of the Fund to
obtain,  at  reasonable  expense,  the "best  execution"  (prompt  and  reliable
execution at the most  favorable  price  obtainable) of such  transactions.  The
Manager  need  not seek  competitive  commission  bidding,  but is  expected  to
minimize the  commissions  paid to the extent  consistent  with the interest and
policies of the Fund as established by its Board of Trustees.

      Under the advisory agreement,  the Manager is authorized to select brokers
other than affiliates that provide  brokerage  and/or research  services for the
Fund and/or the other  accounts  over which the Manager or its  affiliates  have
investment  discretion.  The commissions paid to such brokers may be higher than
another  qualified  broker would have charged if a good faith  determination  is
made by the Manager that the  commission  is fair and  reasonable in relation to
the services provided. Subject to the foregoing considerations,  the Manager may
also consider sales of shares of the Fund and other investment companies managed
by the Manager or its affiliates as a factor in the selection of brokers for the
Fund's portfolio transactions.

   
Description  of  Brokerage  Practices  Followed by the  Manager.  Subject to the
provisions of the  Investment  Advisory  Agreement and the  procedures and rules
described  above,  allocations  of brokerage are generally made by the Manager's
portfolio  traders  based  upon  recommendations  from the  Manager's  portfolio
managers. In certain instances, portfolio managers may directly place trades and
allocate  brokerage,  also subject to the provisions of the Investment  Advisory
Agreement  and the  procedures  and  rules  described  above.  In  either  case,
brokerage  is  allocated  under  the  supervision  of  the  Manager's  executive
officers.  As most purchases made by the Fund are principal  transactions at net
prices,  the Fund does not incur  substantial  brokerage costs. The Fund usually
deals directly with the selling or purchasing  principal or market maker without
incurring  charges  for the  services  of a broker  on its  behalf  unless it is
determined  that a better  price or execution  may be obtained by utilizing  the
services  of a broker.  Purchases  of  portfolio  securities  from  underwriters
include a commission or concession  paid by the issuer to the  underwriter,  and
purchases  from dealers  include a spread  between the bid and asked price.  The
Fund  seeks to obtain  prompt  execution  of orders  at the most  favorable  net
prices.  When the Fund  engages in an option  transaction,  ordinarily  the same
broker will be used for the  purchase or sale of the option and any  transaction
in the securities to which the option relates. When possible,  concurrent orders
to purchase or sell the same  security by more than one of the accounts  managed
by the  Manager  or its  affiliates  are  combined.  The  transactions  effected
pursuant  to such  combined  orders are  averaged as to price and  allocated  in
accordance  with the purchase or sale orders  actually  placed for each account.
Other funds  advised by the Manager  have  investment  objectives  and  policies
similar to those of the Fund.  Such other  funds may  purchase  or sell the same
securities at the same time as the Fund, which could affect the supply and price
of such  securities.  If two or more of such funds purchase the same security on
the same day from the same  dealer,  the  Manager  may  average the price of the
transactions and allocate the average among such funds.

      The research  services  provided by a particular broker may be useful only
to one or more of the advisory  accounts of the Manager and its affiliates,  and
investment  research received for the commissions of those other accounts may be
useful both to the Fund and one or more of such other  accounts.  Such research,
which may be  supplied by a third  party at the  instance of a broker,  includes
information  and analyses on  particular  companies  and  industries  as well as
market or economic trends and portfolio  strategy,  receipt of market quotations
for portfolio  evaluations,  information systems,  computer hardware and similar
products  and  services.  If a research  service  also  assists the Manager in a
non-research  capacity (such as bookkeeping or other administrative  functions),
then only the percentage or component that provides assistance to the Manager in
the investment  decision-making  process may be paid for in commission  dollars.
The Board of  Trustees  permits the Manager to use  concessions  on  fixed-price
offerings  to obtain  research,  in the same manner as is  permitted  for agency
transactions.  The Board also permits the Manager to use stated  commissions  on
secondary  fixed-income  agency trades to obtain  research  where the broker has
represented  to Manager that:  (i) the trade is not from or for the broker's own
inventory,  (ii) the trade was  executed by the broker on an agency basis at the
stated commission, and (iii) the trade is not a riskless principal transaction.

      The research services provided by brokers broaden the scope and supplement
the research activities of the Manager, by making available additional views for
consideration  and  comparisons,  and by enabling  the Manager to obtain  market
information  for the  valuation of  securities  held in the Fund's  portfolio or
being  considered  for  purchase.  The Manager  provides  information  as to the
commissions paid to brokers furnishing such services together with the Manager's
representation that the amount of such commissions was reasonably related to the
value or benefit of such services.
    

Performance of the Fund

   
      As  described  in the  Prospectus,  from  time to time  the  "standardized
yield," "dividend yield," "tax-equivalent yield," "average annual total return,"
"cumulative  total return," "average annual total return at net asset value" and
"total return at net asset value" of an investment in a class of Fund shares may
be advertised. An explanation of how yields and total returns are calculated for
each class and the components of those calculations is set forth below.

      The Fund's  advertisements  of its performance data must, under applicable
rules of the  Securities  and Exchange  Commission,  include the average  annual
total returns for each  advertised  class of shares of the Fund for the 1, 5 and
10-year  periods  (or the  life of the  class,  if less)  ending  as of the most
recently-ended  calendar quarter prior to the publication of the  advertisement.
This enables an investor to compare the Fund's performance to the performance of
other  funds  for the same  periods.  However,  a number  of  factors  should be
considered  before using such  information as a basis for comparison  with other
investments.  An  investment  in the Fund is not  insured;  its  yield and total
returns are not guaranteed  and normally will  fluctuate on a daily basis.  When
redeemed,  an  investor's  shares may be worth more or less than their  original
cost.  Yield and total returns for any given past period are not a prediction or
representation  by the Fund of future  yields or rates of return.  The yield and
total  returns of each  class of shares of the Fund are  affected  by  portfolio
quality,  portfolio  maturity,  the type of  investments  the Fund holds and its
operating expenses allocated to the particular class.

      o Yield

      o  Standardized  

Yield. The "standardized yield" (referred to as "yield") is shown for a class of
shares for a stated 30-day period. It is not based on actual  distributions paid
by the Fund to  shareholders in the 30-day period,  but is a hypothetical  yield
based upon the net investment  income from the Fund's portfolio  investments for
that period.  It may  therefore  differ from the  "dividend  yield" for the same
class of shares,  described below. It is calculated using the following  formula
set forth in rules adopted by the Securities and Exchange  Commission , designed
to assure uniformity in the way that all funds calculate their yields:
    

Standardized ~Yield ~ = ~ 2~ [~ (~ {a-b} over cd ~ +~ 1~ ) SUP 6~ -~ 1~ ]

      The symbols above represent the following factors:

      a  =dividends and interest earned during the 30-day period.
      b  =expenses  accrued  for the  period  (net  of any  expense
          reimbursements).
      c   =the average daily number of shares of that class  outstanding  during
          the 30-day period that were entitled to receive dividends.
      d   =the maximum offering price per share of that class on the last day of
          the period, adjusted for undistributed net investment income.

   
     The  standardized  yield for a 30-day  period may differ from the yield for
other periods.  The SEC formula assumes that the standardized yield for a 30-day
period occurs at a constant rate for a six-month period and is annualized at the
end of the  six-month  period.  Additionally,  because  each  class of shares is
subject to different expenses,  it is likely that the standardized yields of the
Fund's  classes of shares  will  differ for any  30-day  period.  For the 30-day
period ended September 30, 1997, the standardized  yields for the Fund's classes
of shares were as follows:

Without Deducting Sales Charge          With Sales Charge Deducted

Class A:  4.82%                           5.06%
Class B:  4.30%                           N/A
Class C:  4.29%                           N/A

      o Tax-Equivalent  Yield. The  "tax-equivalent  yield" of a class of shares
adjusts the Fund's  current yield,  as calculated  above,  by a stated  combined
Federal  and  state  tax  rate.  The tax  equivalent  yield is based on a 30-day
period, and is computed by dividing the tax-exempt portion of the Fund's current
yield (as calculated above) by one minus a stated income tax rate and adding the
result  to the  portion  (if  any)  of the  Fund's  current  yield  that  is not
tax-exempt.  The tax-equivalent  yield may be used to compare the tax effects of
income  derived  from the Fund with income from taxable  investments  at the tax
rates stated. Appendix B includes a tax equivalent yield table, based on various
effective  tax  brackets  for  individual  taxpayers.   Such  tax  brackets  are
determined by a taxpayer's  Federal  taxable  income (the net amount  subject to
Federal income tax after deductions and exemptions).  The  tax-equivalent  yield
table assumes that the investor is taxed at the highest  bracket,  regardless of
whether a switch to non-taxable investments would cause a lower bracket to apply
and that the  investor is not subject to the  Alternative  Minimum Tax, and that
state income tax payments are fully  deductible for Federal income tax purposes.
For taxpayers with income above certain  levels,  otherwise  allowable  itemized
deductions are limited. The Fund's  tax-equivalent yields for its Class A, Class
B and Class C shares for the 30-day period ended  September 30, 1997 were 7.98%,
7.12% and 7.10%, respectively, for an individual in the 39.6% Federal income tax
bracket.

      o Dividend Yield . The Fund may quote a "dividend yield" for each class of
its shares.  Dividend  yield is based on the dividends paid on shares of a class
during the actual dividend period. To calculate dividend yield, the dividends of
a class  declared  during a stated  period  are  added  together  and the sum is
multiplied by 12 (to  annualize  the yield) and divided by the maximum  offering
price on the last day of the dividend period. The formula is shown below:

      Dividend Yield =    dividends  paid  x  12/maximum offering
                               price (payment date)
 
      The maximum offering price for Class A shares includes the maximum initial
sales charge.  The maximum  offering price for Class B and Class C shares is the
net asset value per share, without considering the effect of contingent deferred
sales charges.  The Class A dividend yield may also be quoted without  deducting
the maximum initial sales charge .

      The dividend yields for the 30-day period ended September 30, 1997 were as
follows:

Without Deducting Sales Charge           With Sales Charge Deducted

Class A:  4.83%                           5.07%
Class B:  4.31%                           N/A
Class C:  4.31%                           N/A
    

      o  Total Return Information.

      o Average Annual Total Returns.  The "average annual total return" of each
class  is an  average  annual  compounded  rate of  return  for  each  year in a
specified number of years. It is the rate of return based on the change in value
of a hypothetical  initial  investment of $1,000 ("P" in the formula below) held
for a number of years  ("n") to  achieve  an Ending  Redeemable  Value  ("ERV"),
according to the following formula:

               LEFT ( {~ERV~} OVER P~ right) SUP
            {1/n}~-1~=~Average~Annual~Total~ Return

   
      The "average  annual total  return" on an  investment in Class A shares of
the Fund for the one , five and ten year periods  ended  September  30, 1997 was
4.07%,  5.71% and 8.36%,  respectively.  The "average annual total return" on an
investment  in Class B shares of the Fund for the one year ended  September  30,
1997 was 3.43%.  For the period from  inception of Class B shares on May 3, 1993
through  September  30, 1997,  the average  annual  total return was 4.81%.  The
"average annual total return" on an investment in Class C shares of the Fund for
the one year ended  September 30, 1997 was 7.48%.  For the period from inception
of Class C shares on August 29, 1995,  through  September 30, 1997,  the average
annual total return was 7.47%.
    

      o Cumulative  Total Return.  The  "cumulative  total  return"  calculation
measures the change in the value of a hypothetical  investment of $1,000 over an
entire period of years. Its calculation uses some of the same factors as average
annual  total  return,  but it does not  average the rate of return on an annual
basis. Cumulative total return is determined as follows:

               {ERV~-~P} over P ~ =~Total~Return

   
      In calculating total returns for Class A shares, the current maximum sales
charge of 4.75% (as a  percentage  of the offering  price) is deducted  from the
initial  investment  ("P")  (unless the return is shown at net asset  value,  as
discussed  below).  For Class B shares,  the payment of the contingent  deferred
sales charge of 5.0% for the first year,  4.0% for the second year, 3.0% for the
third and fourth years,  2.0% in the fifth year, 1.0% in the sixth year and none
thereafter is applied,  as described in the Prospectus.  For Class C shares, the
payment of the 1.0% contingent  deferred sales charge for the first 12 months is
applied,  as described  in the  Prospectus.  Total  returns also assume that all
dividends and capital gains  distributions  during the period are  reinvested to
buy additional  shares at net asset value per share,  and that the investment is
redeemed at the end of the period.  The "total return" on an investment in Class
A shares of the Fund  (using the  method  described  above) for the period  from
November 11, 1986  (inception  of the Fund)  through  September  30,  1997,  was
123.18%.  The cumulative  total return on Class B shares for the period from May
3, 1993  (inception of the class)  through  September  30, 1997 was 23.03%.  The
cumulative  total  return on the Class C shares for the period  from  August 29,
1995 (inception of the class) through September 30, 1997 was 16.23%.

      o Total  Returns at Net Asset  Value.  From time to time the Fund may also
quote an average  annual total  return at net asset value or a cumulative  total
return at net asset value for Class A, Class B or Class C shares.  Each is based
on the  difference  in net asset value per share at the beginning and the end of
the  period  for a  hypothetical  investment  in that  class of shares  (without
considering  front-end  or  contingent  deferred  sales  charges) and takes into
consideration the reinvestment of dividends and capital gains distributions. The
"total  return at net asset value" on the Fund's Class A shares for the one-year
period ended  September 30, 1997 was 9.25%.  The total return at net asset value
for the Fund's Class B shares for the year ended  September  30, 1997 was 6.75%.
The total return at net asset value for the Fund's Class C shares for the period
ended September 30, 1997 was 8.89%.
    

      Total return  information  may be useful to  investors  in  reviewing  the
performance  of the  Fund's  Class A, Class B or Class C shares.  However,  when
comparing total return of an investment in Class A, Class B or Class C shares of
the Fund, a number of factors should be considered before using such information
as a basis for comparison before using such information with other investments.

   
      o Other Performance  Comparisons.  From time to time, the Fund may publish
the  ranking  of the  performance  of its Class A,  Class B or Class C shares by
Lipper Analytical  Services,  Inc. ("Lipper"),  a widely-recognized  independent
mutual fund  monitoring  service.  Lipper  monitors the performance of regulated
investment  companies,  including  the Fund,  and ranks  their  performance  for
various  periods based on  categories  relating to  investment  objectives.  The
performance of the Fund is ranked  against (i) all other bond funds,  other than
money market funds, and (ii) all other insured  municipal debt funds. The Lipper
performance rankings are based on total returns that include the reinvestment of
capital gains  distributions  and income dividends but do not take sales charges
or taxes  into  consideration.  From  time to time the Fund may  include  in its
advertisement and sales literature performance  information about the Fund cited
in other  newspapers  and  periodicals  such as The New York  Times,  which  may
include  performance  quotations  from  other  sources,   including  Lipper  and
Morningstar.  The  performance  of the Fund's Class A, Class B or Class C shares
may be compared in publications to (i) the performance of various market indices
or to other  investments for which reliable  performance data is available,  and
(ii)  to  averages,   performance  rankings  or  other  benchmarks  prepared  by
recognized mutual fund statistical services.
    

      From time to time the Fund may publish the star ranking of the performance
of its Class A, Class B or Class C shares by  Morningstar,  Inc., an independent
mutual fund monitoring service.
   
 Morningstar ranks mutual funds in broad investment  categories:  domestic stock
funds,  international stock funds,  taxable bond funds and municipal bond funds,
based on  risk-adjusted  total investment  return.  The Fund is ranked among the
municipal bond funds. Investment return measures a fund's or class's one, three,
five and ten-year  average  annual total returns  (depending on the inception of
the fund or class) in excess of the 90-day  U.S.  Treasury  bill  returns  after
considering  the fund's sales  charges and  expenses.  Risk measures a fund's or
class's  performance  below the 90-day  U.S.  Treasury  bill  returns.  Risk and
investment return are combined to produce star rankings  reflecting  performance
relative to the average fund in a fund's  category.  Five stars is the "highest"
ranking (top 10%),  four stars is "above  average" (next 22.5%),  three stars is
"average"  (next 35%), two stars is "below average" (next 22.5%) and one star is
"lowest"  (bottom 10%). The current star ranking is the fund's or class's 3-year
ranking or its combined 3- and 5-year ranking (weighted 60%/40% respectively, or
its  combined  3-.  5-  and  10-year   ranking   (weighted  40%,  30%  and  30%,
respectively),  depending on the  inception  of the fund or class.  Rankings are
subject to change monthly.
    

      The Fund may also  compare its  performance  to that of other funds in its
Morningstar  Category.  In  addition  to its  star  rankings,  Morningstar  also
categorizes  and compares a fund's  3-year  performance  based on  Morningstar's
classification of the fund's investments and investment style, rather than how a
fund  defines its  investment  objective.  Morningstar's  four broad  categories
(domestic  equity,  international  equity,  municipal bond and taxable bond) are
each  further  subdivided  into  categories  based on types of  investments  and
investment  styles.  Those comparisons by Morningstar are based on the same risk
and return  measurements  as its star rankings but do not consider the effect of
sales charges.

      Investors  may also wish to compare the Fund's Class A, Class B or Class C
return to the  returns  on fixed  income  investments  available  from banks and
thrift institutions,  such as certificates of deposit,  ordinary interest-paying
checking  and  savings  accounts,  and  other  forms of fixed or  variable  time
deposits,  and various other  instruments such as Treasury bills.  However,  the
Fund's  returns and share price are not guaranteed or insured by the FDIC or any
other agency and will fluctuate daily, while bank depository  obligations may be
insured by the FDIC and may provide  fixed rates of return,  and Treasury  bills
are guaranteed as to principal and interest by the U.S. government.  In order to
compare  the  Fund's  dividends  to the rate of return on  taxable  investments,
Federal income taxes on such investments should be considered.

      From time to time, the Fund's  Manager may publish  rankings or ratings of
the Manager (or Transfer Agent),  or, on the investor  services provided by them
to shareholders of the Oppenheimer funds, other than the performance rankings of
the   Oppenheimer   funds    themselves.    Those   ratings   or   rankings   of
shareholder/investor services by a third party may compare the Oppenheimer funds
services  to those of other  mutual  fund  families  selected  by the  rating or
ranking  services,  and may be based upon the  opinions of the rating or ranking
service  itself,  based on its  research or  judgment,  or based upon surveys of
investors, brokers, shareholders or others.

Distribution and Service Plans

   
      The Fund has  adopted a Service  Plan for Class A shares and  Distribution
and Service Plans for Class B and Class C shares of the Fund under Rule 12b-1 of
the Investment  Company Act pursuant to which the Fund will make payments to the
Distributor  for  its  services  in  connection  with  the  distribution  and/or
servicing of the shares of that class, as described in the Prospectus. Each Plan
has been  approved by a vote of (i) the Board of Trustees , including a majority
of the Independent Trustees,  cast in person at a meeting called for the purpose
of voting on that Plan,  and (ii) the holders of a "majority" (as defined in the
Investment  Company Act) of the shares of each class.  For the  Distribution and
Service  Plan for Class C shares,  that vote was cast by the Manager as the sole
initial holder of Class C shares.
    

      In addition,  under the Plans, the Manager and the  Distributor,  in their
sole discretion,  from time to time, may use their own resources  (which, in the
case of the Manager,  may include profits from the advisory fee it receives from
the Fund), at no cost to the Fund to make payments to brokers, dealers, or other
financial  institutions  (each is referred to as a "Recipient"  under the Plans)
for distribution and administrative  services they perform.  The Distributor and
the Manager  may, in their sole  discretion,  increase or decrease the amount of
payments they make from their own resources to Recipients.

      Unless  terminated as described below,  each Plan continues in effect from
year to year but only as long as its  continuance  is  specifically  approved at
least annually by the Board of Trustees and its  Independent  Trustees by a vote
cast  in  person  at a  meeting  called  for  the  purpose  of  voting  on  such
continuance.  Each Plan may be  terminated at any time by the vote of a majority
of the  Independent  Trustees or by the vote of the holders of a "majority"  (as
defined in the Investment  Company Act) of the outstanding shares of that class.
No Plan may be amended to increase  materially the amount of payments to be made
unless such amendment is approved by  shareholders  of the class affected by the
amendment. In addition, because Class B shares of the Fund automatically convert
into Class A shares after six years,  the Fund is required by a  Securities  and
Exchange  Commission  Rule to obtain the  approval of Class B as well as Class A
shareholders for a proposed  amendment to the Class A Plan that would materially
increase payments under the Plan. Such vote must be by a "majority" of the Class
A and  Class B  shares  (as  defined  in the  Investment  Company  Act),  voting
separately by class.  All material  amendments must be approved by the Board and
the Independent Trustees.

   
      While the Plans are in effect,  the  Treasurer  of the Trust is to provide
separate  written  reports to the Board of Trustees at least  quarterly  for its
review,  detailing the amount of all payments  made  pursuant to each Plan,  the
purpose for which the payment was made and the identity of each  Recipient  that
received  any such  payment.  The report for the Class B Plan shall also include
the Distributor's  distribution  costs for the fiscal period, and such costs for
previous  quarters that have been carried forward as explained in the Prospectus
and below.  Those  reports  will be subject  to the review and  approval  of the
Independent  Trustees in the exercise of their fiduciary duty. Each Plan further
provides  that while it is in effect,  the  selection  and  nomination  of those
Trustees  who are not  "interested  persons"  of the Trust is  committed  to the
discretion of the Independent Trustees. This does not prevent the involvement of
others in such  selection and  nomination  if the final  decision as to any such
selection or nomination is approved by a majority of the Independent Trustees.

      Under the Plans,  no payment will be made to any  Recipient in any quarter
if the  aggregate  net asset value of all Fund shares held by the  Recipient for
itself and its  customers did not exceed a minimum  amount,  if any, that may be
determined  from  time  to  time  by a  majority  of the  Independent  Trustees.
Initially,  the Board of Trustees  has set the fee at the maximum  rate  allowed
under the Plans and set no minimum  amount.  For the fiscal year ended September
30, 1997,  payments  under the Class A Plan totaled  $208,515,  all of which was
paid by the Distributor to Recipients,  including $9,873 paid to an affiliate of
the  Distributor.  Any  unreimbursed  expenses  incurred with respect to Class A
shares for any fiscal year by the Distributor may not be recovered in subsequent
fiscal years.  Payments  received by the Distributor under the Class A Plan will
not be used to pay any interest expense,  carrying  charges,  or other financial
costs, or allocation of overhead by the Distributor.
    

      The Class B and Class C Plans  allow the service fee payment to be paid by
the  Distributor  to  Recipients  in advance  for the first year such shares are
outstanding,   and  thereafter  on  a  quarterly  basis,  as  described  in  the
Prospectus.  The advance payment is based on the net asset value of shares sold.
Pursuant to the Plans,  service fee payments by the  Distributor  to  Recipients
will be made (i) in  advance  for the first  year Class B and Class C shares are
outstanding,  following  the purchase of shares,  in an amount equal to 0.25% of
the net asset value of the shares  purchased by the  Recipient or its  customers
and (ii) thereafter,  on a quarterly basis, computed as of the close of business
each day at an annual  rate of 0.25% of the  average  daily  net asset  value of
Class B and Class C shares held in accounts of the Recipient or its customers.
   
An exchange of shares does not entitle the Recipient to an advance  service fee
payment.  In the event Class B and Class C shares are redeemed  during the first
year such shares are outstanding, the Recipient will be obligated to repay a pro
rata  portion of the advance of the service fee payment for those  shares to the
Distributor.  Payments  made under the Class B Plan during the fiscal year ended
September  30,  1997  totaled  $172,866,  including  $2,397  paid  to  a  dealer
affiliated  with the  Distributor  and  $141,004  retained  by the  Distributor.
Payments under the Class C Plan during the fiscal year ended  September 30, 1997
totaled $17,146, of which $12,061 was retained by the Distributor.

      Although  the  Class B and the Class C Plans  permit  the  Distributor  to
retain both the asset-based sales charges and the service fee on such shares, or
to pay  Recipients  the  service fee on a quarterly  basis,  without  payment in
advance, the Distributor  presently intends to pay the service fee to Recipients
in the manner  described above. A minimum holding period may be established from
time to time  under the Class B and Class C Plans by the Board.  Initially,  the
Board has set no minimum  holding  period.  All  payments  under the Class B and
Class C Plans are subject to the limitations imposed by the Conduct Rules of the
National  Association  of  Securities  Dealers,  Inc. on payments of asset based
sales charges and service fees.
    

      The  Class  B  and  Class  C  Plans  provide  for  the  Distributor  to be
compensated at a flat rate, whether the Distributor's  distribution expenses are
more or less  than  the  amounts  paid  by the  Fund  during  that  period.  The
Distributor  retains the asset-based sales charge on Class B shares  outstanding
for less  than 6 years.  As to  Class C  shares,  the  Distributor  retains  the
asset-based  sales charge during the first year shares are  outstanding and pays
the asset-based sales charges as an ongoing  commission to the dealer on Class C
shares  outstanding  for more than a year or more. Such payments are made to the
Distributor  under the Plans in recognition  that the Distributor (i) pays sales
commissions  to  authorized  brokers  and  dealers  at the time of sale and pays
service fees, as described in the Prospectus,  (ii) may finance such commissions
and/or the advance of the service fee payment to  Recipients  under those Plans,
or may provide such  financing  from its own  resources,  or from an  affiliate,
(iii) employs personnel to support distribution of shares, and (iv) may bear the
costs of sales  literature,  advertising  and  prospectuses  (other  than  those
furnished to current  shareholders),  and state "blue sky" registration fees and
certain other distribution expenses.


ABOUT YOUR ACCOUNT

How To Buy Shares

     Alternative Sales  Arrangements - Class A, Class B and Class C Shares.  The
availability of three classes of shares permits an investor to choose the method
of purchasing  shares that is more  beneficial to the investor  depending on the
amount of the purchase,  the length of time the investor  expects to hold shares
and other relevant  circumstances.  Investors should understand that the purpose
and function of the  deferred  sales  charge and  asset-based  sales charge with
respect to Class B and Class C shares are the same as those of the initial sales
charge with respect to Class A shares.  Any salesperson or other person entitled
to  receive   compensation  for  selling  Fund  shares  may  receive   different
compensation with respect to one class of shares than the other. The Distributor
will not accept any order for  $500,000  or more of Class B shares or $1 million
or more of Class C shares,  on behalf of a single investor (not including dealer
"street  name"  or  omnibus   accounts)   because  generally  it  will  be  more
advantageous for that investor to purchase Class A shares of the Fund instead.

      The three  classes  of  shares  each  represent  an  interest  in the same
portfolio investments of the Fund. However, each class has different shareholder
privileges  and  features.  The net income  attributable  to Class B and Class C
shares and the  dividends  payable  on such  Class B and Class C shares  will be
reduced by  incremental  expenses  borne  solely by that  class,  including  the
asset-based sales charge to which Class B and Class C shares are subject.

      The  conversion  of Class B shares  to Class A shares  after  six years is
subject to the  continuing  availability  of a private  letter  ruling  from the
Internal Revenue Service, or an opinion of counsel or tax adviser, to the effect
that the  conversion  of Class B shares does not  constitute a taxable event for
the holder under Federal  income tax law. If such a revenue ruling or opinion is
no longer available, the automatic conversion feature may be suspended, in which
event no further conversions of Class B shares would occur while such suspension
remained in effect.  Although Class B shares could then be exchanged for Class A
shares on the basis of relative net asset value of the two classes,  without the
imposition of a sales charge or fee, such  exchange  could  constitute a taxable
event for the holder, and absent such exchange, Class B shares might continue to
be subject to the asset-based sales charge for longer than six years.

   
      The  methodology  for  calculating  the net  asset  value,  dividends  and
distributions  of the Fund's Class A, Class B and Class C shares  recognizes two
types of expenses.  General  expenses  that do not pertain  specifically  to any
class  are  allocated  pro  rata to the  shares  of  each  class,  based  on the
percentage  of the net assets of such class to the Fund's total net assets,  and
then  equally to each  outstanding  share  within a given  class.  Such  general
expenses  include (i) management  fees, (ii) legal,  bookkeeping and audit fees,
(iii)  printing  and  mailing  costs  of  shareholder   reports,   Prospectuses,
Statements  of   Additional   Information   and  other   materials  for  current
shareholders,  (iv) fees to unaffiliated Trustees, (v) custodian expenses,  (vi)
share issuance costs,  (vii)  organization and start-up costs,  (viii) interest,
taxes  and  brokerage  commissions,  and (ix)  non-recurring  expenses,  such as
litigation costs.  Other expenses that are directly  attributable to a class are
allocated  equally to each  outstanding  share within that class.  Such expenses
include (a) Distribution  and/or Service Plan fees, (b) transfer and shareholder
servicing  agent fees and expenses,  (c)  registration  fees and (d) shareholder
meeting  expenses,  to the extent that such expenses pertain to a specific class
rather than to the Fund as a whole.

     Determination of Net Asset Values Per Share. The net asset values per share
of Class A,  Class B and  Class C shares  of the Fund are  determined  as of the
close of business of The New York Stock  Exchange (the  "Exchange")  on each day
that the  Exchange  is open,  by  dividing  the value of the  Fund's  net assets
attributable  to that  Class by the  number  of shares  of that  class  that are
outstanding.  The Exchange  normally closes at 4:00 P.M., New York time, but may
close earlier on some days (for example,  in case of weather  emergencies  or on
days  falling  before or after a holiday).  The  Exchange's  most recent  annual
announcement  (which is  subject  to  change)  states  that it will close on New
Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,  Memorial
Day,  Independence  Day, Labor Day,  Thanksgiving  Day and Christmas Day. It may
also close on other  days.  Dealers  other than  Exchange  members  may  conduct
trading in Municipal  Securities on certain days on which the Exchange is closed
(including  weekends and holidays) or after 4:00 p.m. on a regular business day.
Because the Fund's net asset values will not be  calculated  on those days,  the
Fund's net asset value per share may be significantly affected on such days when
shareholders may not purchase or redeem shares.

      The Board of Trustees has established  procedures for the valuation of the
Fund's securities,  generally as follows: (i) long-term debt securities having a
remaining maturity in excess of 60 days are valued based on the mean between the
"bid" and "asked" prices  determined by a portfolio  pricing service approved by
the Board of Trustees or obtained by the Manager from two active  market  makers
in the security on the basis of reasonable inquiry; (ii) a non-money market fund
will value (a) debt  instruments  that had a maturity of more than 397 days when
issued, (b) debt instruments that had a maturity of 397 days or less when issued
and have a remaining  maturity in excess of 60 days,  and (c)  non-money  market
type debt  instruments  that had a maturity  of 397 days or less when issued and
have a remaining  maturity of sixty days or less , at the mean between "bid" and
"ask"asked"  prices determined by a pricing service approved by the Fund's Board
of Trustees or, if  unavailable,  obtained by the Manager from two active market
makers  in  the  security  on the  basis  of  reasonable  inquiry;  (iii)  money
market-type debt securities held by a non- money market fund that had a maturity
of less than 397 days when issued  that have a remaining  maturity of 60 days or
less and debt  instruments  held by a money  market  fund that have a  remaining
maturity of 397 days or less, shall be valued at cost, adjusted for amortization
of  premiums  and  accretion  of  discounts;   and  (iv)  securities  (including
restricted securities) not having readily-available market quotations are valued
at fair value determined under the Board's procedures.  If the Manager is unable
to locate two market makers willing to give quotes (see (i) and (ii) above), the
security may be priced at the mean between the "bid" and "asked" prices provided
by a single  active  market maker (which in certain cases may be the "bid" price
if no "asked"  price is available)  provided that the Manager is satisfied  that
the firm  rendering  the  quotes is  reliable  and that the quotes  reflect  the
current market value.
    

      In the  case of  Municipal  Securities,  U.S.  Government  securities  and
corporate  bonds,  when last sale information is not generally  available,  such
pricing procedures may include "matrix" comparisons to the prices for comparable
instruments on the basis of quality,  yield, maturity, and other special factors
involved  (such as the  tax-exempt  status  of the  interest  paid by  Municipal
Securities).  The  Manager  may use  pricing  services  approved by the Board of
Trustees to price any of the types of securities  described  above.  The Manager
will monitor the accuracy of such pricing services,  which may include comparing
prices  used for  portfolio  evaluation  to  actual  sales  prices  of  selected
securities.

      With respect to valuation of securities which are in default in payment of
principal or interest or, as determined by the Manager,  in significant  risk of
such default  (the  "Defaulted  Securities")  and which are covered by insurance
obtained  by the Fund,  the value of the  insurance  guaranteeing  interest  and
principal  payments  will be an element of the net asset value per share for the
Fund. The value of the insurance will be equal to the difference between (i) the
market value of the Defaulted  Securities  assuming the exercise of the right to
obtain  a  Secondary  Market  Insurance  Policy  (less  the  insurance   premium
attributable  to the  purchase of such policy) and (ii) the market value of such
Defaulted  Securities not covered by a Secondary  Market  Insurance  Policy.  In
addition,  the ability of Financial  Guaranty to meet its commitments  under the
Fund's  insurance  policy,  including the commitments to issue Secondary  Market
Insurance  Policies,  will be  considered.  If an occurrence  were to take place
after the value of a security in a portfolio was so  established  but before the
net asset value per share is determined  which was likely to  materially  change
the net asset value, then such security would be valued under procedures adopted
by the Trustees to make such fair value determination.

   
      Puts,  calls,  Interest Rate Futures and Municipal  Bond Index Futures are
valued at the last  sales  price on the  principal  exchange  on which  they are
traded or on  NASDAQ,  as  applicable,  or as  determined  by a pricing  service
approved by the Board of Trustees or by the Manager. If there were no sales that
day,  value shall be the last sale price on the  preceding  trading day if it is
within the  spread of the  closing  "bid" and  "asked"  prices on the  principal
exchange  or on NASDAQ on the  valuation  date,  or, if not,  value shall be the
closing  "bid" price on the  principal  exchange  or on NASDAQ on the  valuation
date. If the put,  call or future is not traded on an exchange or on NASDAQ,  it
shall be valued at the mean  between  "bid" and "asked"  prices  obtained by the
Manager from two active  market  makers (which in certain cases may be the "bid"
price if no "asked" price is available).

      When the Fund writes an option, an amount equal to the premium received is
included in the Fund's  Statement of Assets and  Liabilities  as an asset and an
equivalent credit is included in the liability  section.  The credit is adjusted
("marked-to-market")  to reflect the current market value of the call or put. In
determining the Fund's gain on investments, if a call or put written by the Fund
is exercised,  the proceeds are increased by the premium received.  If a call or
put  written  by the Fund  expires,  the Fund  has a gain in the  amount  of the
premium; if the Fund enters into a closing purchase transaction,  it will have a
gain or loss,  depending  on whether the premium  received was more or less than
the cost of the closing  transaction.  If the Fund exercises a put it holds, the
amount the Fund receives on its sale of the underlying  investment is reduced by
the amount of the premium paid by the Fund.
    

AccountLink.  When shares are purchased through AccountLink,  each purchase must
be at least $25.  Shares  will be  purchased  on the  regular  business  day the
Distributor  is instructed to initiate the Automated  Clearing House transfer to
buy the  shares.  Dividends  will  begin to accrue on  shares  purchased  by the
proceeds of ACH  transfers on the business day the Fund  receives  Federal Funds
for the purchase  through the ACH system  before the close of The New York Stock
Exchange.  The Exchange  normally  closes at 4:00 p.m., but may close earlier on
certain  days.  If the Federal  Funds are  received on a business  day after the
close of the Exchange,  the shares will be purchased and dividends will begin to
accrue on the next regular  business day after such Federal  Funds are received.
The proceeds of ACH transfers are normally received by the Fund three days after
the transfers are initiated.  The  Distributor  and the Fund are not responsible
for any delays in purchasing shares resulting from delays in ACH transmissions.

   
Reduced Sales Charges.  As discussed in the  Prospectus,  a reduced sales charge
rate may be obtained for Class A shares under Right of Accumulation  and Letters
of Intent  because of the  economies of sales  efforts and reduction in expenses
realized by the  Distributor,  dealers and brokers  making such sales.  No sales
charge is imposed in certain  other  circumstances  described in the  Prospectus
because  the  Distributor  or  broker  or dealer  incurs  little  or no  selling
expenses.  The  term  "immediate  family"  refers  to  one's  spouse,  children,
grandchildren,  grandparents,  parents,  parents-in-law,  brothers  and sisters,
sons- and  daughters-in-law,  a sibling's  spouse, a spouse's  siblings,  aunts,
uncles, nieces and nephews.  Relations by virtue of a remarriage (step-children,
step-parents, etc.) are included.

which the Distributor acts as the distributor or the Sub-Distributor and include
the following:

Oppenheimer Money Market Fund, Inc.
Oppenheimer Cash Reserves
Centennial Money Market Trust
Centennial Tax Exempt Trust
Centennial Government Trust
Centennial New York Tax Exempt Trust
Centennial California Tax Exempt Trust
Centennial America Fund, L.P.
    

      There is an initial sales charge on the purchase of Class A shares of each
of the Oppenheimer funds except Money Market Funds (under certain  circumstances
described herein, redemption proceeds of Money Market Fund shares may be subject
to a contingent deferred sales charge).

   
      o Letters of Intent.  A Letter of Intent (referred to as a "Letter") is an
investor's  statement in writing to the Distributor of the intention to purchase
Class A shares or Class A and Class B shares of the Fund (and other  Oppenheimer
funds) during a 13-month period (the "Letter of Intent  period"),  which may, at
the investor's  request,  include purchases made up to 90 days prior to the date
of the Letter. The Letter states the investor's  intention to make the aggregate
amount of purchases of shares which,  when added to the  investor's  holdings of
shares of those funds,  will equal or exceed the amount specified in the Letter.
Purchases made by  reinvestment of dividends or  distributions  of capital gains
and  purchases  made at net asset value without sales charge do not count toward
satisfying  the amount of the Letter.  A Letter enables an investor to count the
Class A and Class B shares  purchased  under the  Letter to obtain  the  reduced
sales  charge  rate on  purchases  of Class A  shares  of the  Fund  (and  other
Oppenheimer  funds)  that  applies  under the Right of  Accumulation  to current
purchases  of Class A shares.  Each  purchase of Class A shares under the Letter
will be made at the public  offering  price  (including  the sales  charge) that
applies to a single  lump-sum  purchase  of shares in the amount  intended to be
purchased under the Letter.
    

      In  submitting a Letter,  the  investor  makes no  commitment  to purchase
shares,  but if the  investor's  purchases of shares within the Letter of Intent
period,  when added to the value (at offering price) of the investor's  holdings
of shares on the last day of that  period,  do not equal or exceed the  intended
purchase  amount,  the  investor  agrees to pay the  additional  amount of sales
charge  applicable to such  purchases,  as set forth in "Terms of Escrow," below
(as those  terms may be amended  from time to time).  The  investor  agrees that
shares  equal in value to 5% of the  intended  purchase  amount  will be held in
escrow by the Transfer Agent subject to the Terms of Escrow.  Also, the investor
agrees to be bound by the terms of the Prospectus,  this Statement of Additional
Information  and the  Application  used for such  Letter of Intent,  and if such
terms are  amended,  as they may be from time to time by the  Fund,  that  those
amendments will apply automatically to existing Letters of Intent.

      If the total eligible purchases made during the Letter of Intent period do
not equal or exceed the intended  purchase  amount,  the commissions  previously
paid to the dealer of record  for the  account  and the  amount of sales  charge
retained by the Distributor  will be adjusted to the rates  applicable to actual
total purchases.  If total eligible purchases during the Letter of Intent period
exceed the intended  purchase amount and exceed the amount needed to qualify for
the next sales charge rate reduction set forth in the applicable prospectus, the
sales charges paid will be adjusted to the lower rate,  but only if and when the
dealer  returns  to the  Distributor  the  excess of the  amount of  commissions
allowed or paid to the dealer over the amount of  commissions  that apply to the
actual amount of purchases.  The excess commissions  returned to the Distributor
will be used to purchase additional shares for the investor's account at the net
asset value per share in effect on the date of such purchase, promptly after the
Distributor's receipt thereof.

      In determining  the total amount of purchases made under a Letter,  shares
redeemed by the investor prior to the termination of the Letter of Intent period
will be deducted.  It is the  responsibility  of the dealer of record and/or the
investor  to advise the  Distributor  about the Letter in placing  any  purchase
orders  for the  investor  during  the  Letter  of  Intent  period.  All of such
purchases must be made through the Distributor.

      o Terms of Escrow That Apply to Letters of Intent.

      1. Out of the initial purchase (or subsequent purchases if necessary) made
pursuant to a Letter, shares of the Fund equal in value up to 5% of the intended
purchase amount  specified in the Letter shall be held in escrow by the Transfer
Agent. For example, if the intended purchase amount is $50,000, the escrow shall
be shares valued in the amount of $2,500  (computed at the public offering price
adjusted for a $50,000 purchase).  Any dividends and capital gains distributions
on the escrowed shares will be credited to the investor's account.

      2. If the total minimum investment specified under the Letter is completed
within the thirteen- month Letter of Intent period,  the escrowed shares will be
promptly released to the investor.

      3. If, at the end of the thirteen-month  Letter of Intent period the total
purchases  pursuant  to the Letter are less than the  intended  purchase  amount
specified in the Letter,  the investor must remit to the  Distributor  an amount
equal to the difference between the dollar amount of sales charges actually paid
and the amount of sales  charges  which would have been paid if the total amount
purchased  had been made at a single  time.  Such sales charge  adjustment  will
apply to any shares  redeemed  prior to the  completion  of the Letter.  If such
difference  in sales charges is not paid within twenty days after a request from
the Distributor or the dealer,  the Distributor  will,  within sixty days of the
expiration  of the Letter,  redeem the number of escrowed  shares  necessary  to
realize such difference in sales charges.  Full and fractional  shares remaining
after such redemption will be released from escrow.  If a request is received to
redeem escrowed shares prior to the payment of such additional sales charge, the
sales charge will be withheld from the redemption proceeds.

      4. By  signing  the  Letter,  the  investor  irrevocably  constitutes  and
appoints the Transfer Agent as  attorney-in-fact to surrender for redemption any
or all escrowed shares.

   
      5. The shares  eligible for  purchase  under the Letter (or the holding of
which may be counted toward  completion of a Letter)  include (a) Class A shares
sold with a front-end  sales charge or subject to a Class A contingent  deferred
sales charge, (b) Class B shares of the other Oppenheimer funds acquired subject
to a  contingent  deferred  sales  charge,  and (c)  Class A or  Class B  shares
acquired in exchange  for either (i) Class A shares sold with a front-end  sales
charge of one of the other  Oppenheimer  funds that were  acquired  subject to a
contingent  deferred  sales  charge  or (ii)  Class B shares of one of the other
Oppenheimer  funds that were  acquired  subject to a contingent  deferred  sales
charge.
    

     6. Shares held in escrow  hereunder  will  automatically  be exchanged  for
shares of another  fund to which an exchange is  requested,  as described in the
section of the Prospectus entitled "How to Exchange Shares," and the escrow will
be transferred to that other fund.

Asset Builder Plans.  To establish an Asset Builder Plan from a bank account,  a
check  (minimum $25) for the initial  purchase must  accompany the  application.
Shares  purchased by Asset  Builder Plan payments from bank accounts are subject
to the redemption  restrictions for recent  purchases  described in "How To Sell
Shares," in the  Prospectus.  Asset  Builder Plans also enable  shareholders  of
Oppenheimer Cash Reserves to use those accounts for monthly automatic  purchases
of shares of up to four other Oppenheimer  funds. If you make payments from your
bank  account  to  purchase  shares  of the  Fund,  your  bank  account  will be
automatically  debited  normally  four  to  five  business  days  prior  to  the
investment dates selected in the Account  Application.  Neither the Distributor,
the  Transfer  Agent  nor the  Fund  shall  be  responsible  for any  delays  in
purchasing shares resulting from delays in ACH transmission.

      There is a front-end  sales charge on the purchase of certain  Oppenheimer
funds,  or a contingent  deferred sales charge may apply to shares  purchased by
Asset Builder payments.  An application should be obtained from the Distributor,
completed  and  returned,  and a prospectus  of the selected  fund(s)  should be
obtained from the Distributor or your financial  advisor before initiating Asset
Builder payments.  The amount of the Asset Builder  investment may be changed or
the  automatic  investments  may be  terminated  at any time by  writing  to the
Transfer Agent. A reasonable  period  (approximately  15 days) is required after
the Transfer  Agent's  receipt of such  instructions to implement them. The Fund
reserves the right to amend,  suspend, or discontinue offering such plans at any
time without prior notice.

Cancellation of Purchase Orders.  Cancellation of purchase orders for the Fund's
shares (for  example,  when a purchase  check is  returned  to the Fund  unpaid)
causes a loss to be incurred  when the net asset  value of the Fund's  shares on
the  cancellation  date is less than on the purchase date. That loss is equal to
the amount of the  decline in the net asset  value per share  multiplied  by the
number of shares in the purchase  order.  The investor is  responsible  for that
loss. If the investor fails to compensate the Fund for the loss, the Distributor
will do so. The Fund may reimburse the  Distributor for that amount by redeeming
shares from any account  registered in that investor's  name, or the Fund or the
Distributor may seek other redress.

Checkwriting. When a check is presented to the Bank for clearance, the Bank will
ask the Fund to redeem a sufficient  number of full and fractional shares in the
shareholder's  account  to cover  the  amount of the  check.  This  enables  the
shareholder to continue  receiving  dividends on those shares until the check is
presented to the Fund. Checks may not be presented for payment at the offices of
the Bank or the Fund's  Custodian.  This  limitation  does not affect the use of
checks  for the  payment  of bills or to obtain  cash at other  banks.  The Fund
reserves  the right to amend,  suspend,  or  discontinue  offering  Checkwriting
privileges at any time without prior notice.

      By choosing the Checkwriting  privilege,  whether you do so by signing the
Account  Application  or by  completing a  Checkwriting  card,  the  individuals
signing (1) represent that they are either the registered owner(s) of the shares
of the Fund, or are an officer,  general partner,  trustee or other fiduciary or
agent,  as  applicable,  duly  authorized  to act on behalf  of such  registered
owner(s);  (2) authorize the Fund, its Transfer Agent and any bank through which
the Fund's drafts  ("checks") are payable (the "Bank"),  to pay all checks drawn
on the Fund account of such  person(s)  and to effect a redemption of sufficient
shares  in that  account  to cover  payment  of such  checks;  (3)  specifically
acknowledge(s)  that if you choose to permit a single  signature on checks drawn
against joint accounts,  or accounts for corporations,  partnerships,  trusts or
other entities, the signature of any one signatory on a check will be sufficient
to authorize  payment of that check and redemption  from an account even if that
account is  registered in the names of more than one person or even if more than
one authorized signature appears on the Checkwriting card or the Application, as
applicable;  and  (4)  understand(s)  that  the  Checkwriting  privilege  may be
terminated  or amended at any time by the Fund and/or the Bank and neither shall
incur  any  liability  for  such  amendment  or  termination  or  for  effecting
redemptions to pay checks reasonably believed to be genuine, or for returning or
not paying checks which have not been accepted for any reason.

How to Sell Shares

     Information on how to sell shares of the Fund is stated in the  Prospectus.
The information  below  supplements the terms and conditions for redemptions set
forth in the Prospectus.

   
      o Selling Shares by Wire.  The wire of redemption  proceeds may be delayed
if the Fund's  custodian  bank is not open for  business  on a day when the Fund
would normally  authorize the wire to be made,  which is usually the Fund's next
regular business day following the redemption. In those circumstances,  the wire
will not be  transmitted  until the next bank  business day on which the Fund is
open for business.  No dividends will be paid on the proceeds of redeemed shares
awaiting transfer by wire.
    

     o  Involuntary  Redemptions.  The Fund's Board of Trustees has the right to
cause the  involuntary  redemption  of the  shares  held in any  account  if the
aggregate  net asset  value of those  shares is less than  $1,000 or such lesser
amount  as the  Board  may  fix.  The  Board of  Trustees  will  not  cause  the
involuntary  redemption of shares in an account if the aggregate net asset value
of the shares has fallen below the stated  minimum  solely as a result of market
fluctuations. Should the Board elect to exercise this right, it may also fix, in
accordance with the Investment  Company Act, the  requirements for any notice to
be given to the  shareholders  in question (not less than 30 days), or the Board
may set requirements for granting permission to the shareholders to increase the
investment,  and set other terms and  conditions so that the shares would not be
involuntarily redeemed.

      o Payments  "In Kind".  The  Prospectus  states  that  payment  for shares
tendered  for  redemption  is  ordinarily  made in cash.  However,  the Board of
Trustees of the Trust may  determine  that it would be  detrimental  to the best
interests  of the  remaining  shareholders  of the  Fund  to make  payment  of a
redemption  order wholly or partly in cash.  In that case,  the Fund may pay the
redemption  proceeds  in  whole  or in  part  by a  distribution  "in  kind"  of
securities  from the portfolio of the Fund, in lieu of cash, in conformity  with
applicable  rules of the  Securities  and  Exchange  Commission.  The  Trust has
elected to be governed by Rule 18f-1 under the Investment  Company Act, pursuant
to which the Fund is obligated to redeem  shares solely in cash up to the lesser
of $250,000 or 1% of the net assets of the Fund during any 90-day period for any
one shareholder. If shares are redeemed in kind, the redeeming shareholder might
incur brokerage or other costs in selling the securities for cash. The method of
valuing  securities  used to make  redemptions  in kind  will be the same as the
method the Fund uses to value its  portfolio  securities  described  above under
"Determination of Net Asset Values Per Share" and that valuation will be made as
of the time the redemption price is determined.

   
Reinvestment  Privilege.  Within six months of a redemption,  a shareholder  may
reinvest all or part of the  redemption  proceeds of (i) Class A shares that you
purchase subject to an initial sales charge or Class A contingent deferred sales
charge  which was paid,  or (ii) Class B shares that were subject to the Class B
contingent  deferred sales charge when redeemed.  The  reinvestment  may be made
without  sales  charge  only in Class A shares  of the Fund or any of the  other
Oppenheimer funds into which shares of the Fund are  exchangeable,  as described
in "How to Exchange  Shares  "below,  at the net asset value next computed after
the Transfer Agent receives the reinvestment order. This reinvestment  privilege
does not apply to Class C shares.  The shareholder  must ask the Distributor for
that privilege at the time of  reinvestment.  Any capital gain that was realized
when the shares were redeemed is taxable,  and  reinvestment  will not alter any
capital  gains tax payable on that gain. If there has been a capital loss on the
redemption, some or all of the loss may not be tax deductible,  depending on the
timing and amount of the  reinvestment.  Under the Internal Revenue Code, if the
redemption  proceeds  of Fund  shares  on  which a sales  charge  was  paid  are
reinvested in shares of the Fund or another of the  Oppenheimer  funds within 90
days of payment of the sales charge,  the  shareholder's  basis in the shares of
the Fund that were redeemed may not include the amount of the sales charge paid.
That would reduce the loss or increase the gain  recognized from the redemption.
However, in that case the sales charge would be added to the basis of the shares
acquired by the  reinvestment  of the redemption  proceeds.  The Fund may amend,
suspend or cease offering this  reinvestment  privilege at any time as to shares
redeemed after the date of such amendment, suspension or cessation.
    

Transfers  of Shares.  Shares are not  subject  to the  payment of a  contingent
deferred  sales  charge  of any  class  at the time of  transfer  to the name of
another person or entity  (whether the transfer  occurs by absolute  assignment,
gift or bequest,  not  involving,  directly or indirectly,  a public sale).  The
transferred shares will remain subject to the contingent  deferred sales charge,
calculated as if the transferee  shareholder had acquired the transferred shares
in the same manner and at the same time as the transferring shareholder. If less
than all shares held in an account are transferred,  and some but not all shares
in the  account  would be  subject  to a  contingent  deferred  sales  charge if
redeemed at the time of transfer,  the  priorities  described in the  Prospectus
under  "How to Buy  Shares"  for the  imposition  of the  Class B or the Class C
contingent  deferred sales charge will be followed in  determining  the order in
which shares are transferred.

Special  Arrangements  for  Repurchase  of Shares from Dealers and Brokers.  The
Distributor is the Fund's agent to repurchase its shares from authorized dealers
or brokers on behalf of their  customers.  The  shareholder  should  contact the
broker or dealer to arrange this type of redemption.  The  repurchase  price per
share will be the net asset value next computed after the  Distributor  receives
an order placed by the dealer or broker, except that if the Distributor receives
a repurchase order from a dealer or broker after the close of The New York Stock
Exchange on a regular business day, it will be processed at that day's net asset
value if the order was received by the dealer or broker from its customers prior
to the time the Exchange closes  (normally that is 4:00 p.m., but may be earlier
on some days) and the order was  transmitted to and received by the  Distributor
prior to its close of business that day (normally  5:00 p.m.).  Ordinarily,  for
accounts redeemed by a broker-dealer under this procedure,  payment will be made
within  three  business  days  after  the  shares  have been  redeemed  upon the
Distributor's  receipt of the required redemption documents in proper form, with
the signature(s) of the registered owners guaranteed on the redemption  document
as described in the Prospectus.

   
Automatic  Withdrawal and Exchange  Plans.  Investors  owning shares of the Fund
valued at $5,000  or more can  authorize  the  Transfer  Agent to redeem  shares
(minimum $50) automatically on a monthly, quarterly, semi-annual or annual basis
under an Automatic  Withdrawal Plan. Shares will be redeemed three business days
prior to the date  requested  by the  shareholder  for  receipt of the  payment.
Automatic withdrawals of up to $1,500 per month may be requested by telephone if
payments are to be made by check payable to all  shareholders of record and sent
to the  address  of record  for the  account  (and if the  address  has not been
changed  within  the  prior  30  days).   Required  minimum  distributions  from
OppenheimerFunds-sponsored  retirement  plans may not be arranged on this basis.
Payments  are  normally  made by  check,  but  shareholders  having  AccountLink
privileges  (see "How To Buy Shares") may arrange to have  Automatic  Withdrawal
Plan payments transferred to the bank account designated on the OppenheimerFunds
New  Account  Application  or  signature-guaranteed   instructions.  Shares  are
normally redeemed  pursuant to an Automatic  Withdrawal Plan three business days
before the date you select in the Account Application.  If a contingent deferred
sales charge applies to the redemption,  the amount of the check or payment will
be reduced  accordingly.  The Fund cannot guarantee  receipt of a payment on the
date requested and reserves the right to amend,  suspend or discontinue offering
such  plans at any time  without  prior  notice.  Because  of the  sales  charge
assessed  on Class A share  purchases,  shareholders  should  not  make  regular
additional  Class  A  share  purchases  while   participating  in  an  Automatic
Withdrawal  Plan.  Class  B  and  Class  C  shareholders  should  not  establish
withdrawal  plans because of the  imposition of the  contingent  deferred  sales
charge on such withdrawals (except where the contingent deferred sales charge is
waived as  described  in the  Prospectus  under  "Waivers of Class B and Class C
Sales Charges").

      By requesting an Automatic  Withdrawal or Exchange Plan,  the  shareholder
agrees to the terms and conditions  applicable to such plans,  as stated below ,
as well as those stated in the Prospectus.  These provisions may be amended from
time to time by the Fund and/or the Distributor.  When adopted,  such amendments
will automatically apply to existing Plans.
    

      o Automatic Exchange Plans.  Shareholders can authorize the Transfer Agent
(on the OppenheimerFunds  Application or  signature-guaranteed  instructions) to
exchange a  pre-determined  amount of shares of the Fund for shares (of the same
class)  of  other  Oppenheimer  funds  automatically  on a  monthly,  quarterly,
semi-annual or annual basis under an Automatic Exchange Plan. The minimum amount
that may be exchanged to each other fund  account is $25.  Exchanges  made under
these plans are subject to the restrictions that apply to exchanges as set forth
in "How to Exchange  Shares" in the  Prospectus  and below in this  Statement of
Additional Information.

      o Automatic Withdrawal Plans. Fund shares will be redeemed as necessary to
meet  withdrawal  payments.  Shares  acquired  without  a sales  charge  will be
redeemed  first and thereafter  shares  acquired with  reinvested  dividends and
capital gains  distributions will be redeemed next,  followed by shares acquired
with a sales  charge,  to the  extent  necessary  to make  withdrawal  payments.
Depending upon the amount withdrawn,  the investor's  principal may be depleted.
Payments  made under such plans should not be considered as a yield or income on
your investment.

   
     It may not be  desirable  to purchase  additional  shares of Class A shares
while maintaining  automatic withdrawals because of the sales charges that apply
to purchases when made. Accordingly,  a shareholder normally may not maintain an
Automatic Withdrawal Plan while simultaneously making regular purchases of Class
A shares.
    

      The Transfer Agent will  administer the  investor's  Automatic  Withdrawal
Plan (the "Plan") as agent for the investor (the  "Planholder") who executed the
Plan authorization and application  submitted to the Transfer Agent. Neither the
Fund nor the Transfer  Agent shall incur any liability to the Planholder for any
action taken or omitted by the Transfer  Agent in good faith to  administer  the
Plan.  Certificates  will not be issued for shares of the Fund purchased for and
held under the Plan,  but the Transfer  Agent will credit all such shares to the
account of the  Planholder  on the records of the Fund.  Any share  certificates
held by a Planholder  may be  surrendered  unendorsed to the Transfer Agent with
the Plan  application so that the shares  represented by the  certificate may be
held under the Plan.

      For  accounts  subject to Automatic  Withdrawal  Plans,  distributions  of
capital gains must be  reinvested  in shares of the Fund,  which will be done at
net asset value without a sales charge.  Dividends on shares held in the account
may be paid in cash or reinvested.

      Redemptions of shares needed to make  withdrawal  payments will be made at
the net asset  value per share  determined  on the  redemption  date.  Checks or
AccountLink  payments  of the  proceeds  of Plan  withdrawals  will  normally be
transmitted  three  business  days prior to the date selected for receipt of the
payment  (receipt  of  payment  on the  date  selected  cannot  be  guaranteed),
according to the choice specified in writing by the Planholder.

      The amount and the  interval of  disbursement  payments and the address to
which  checks  are to be mailed or  AccountLink  payments  are to be sent may be
changed at any time by the  Planholder  by writing to the  Transfer  Agent.  The
Planholder  should allow at least two weeks' time in mailing  such  notification
for the requested  change to be put in effect.  The Planholder may, at any time,
instruct the Transfer Agent by written notice (in proper form in accordance with
the requirements of the  then-current  Prospectus of the Fund) to redeem all, or
any part of, the shares held under the Plan.  In that case,  the Transfer  Agent
will redeem the number of shares  requested  at the net asset value per share in
effect in accordance with the Fund's usual redemption procedures and will mail a
check for the proceeds to the Planholder.

      The Plan may be terminated at any time by the Planholder by writing to the
Transfer  Agent. A Plan may also be terminated at any time by the Transfer Agent
upon receiving  directions to that effect from the Fund. The Transfer Agent will
also terminate a Plan upon receipt of evidence  satisfactory  to it of the death
or  legal  incapacity  of the  Planholder.  Upon  termination  of a Plan  by the
Transfer Agent or the Fund,  shares that have not been redeemed from the account
will be held in  uncertificated  form  in the  name of the  Planholder,  and the
account will continue as a dividend-reinvestment,  uncertificated account unless
and until proper  instructions  are received  from the  Planholder or his or her
executor or guardian, or other authorized person.

   
      To use Class A shares held under the Plan as  collateral  for a debt,  the
Planholder may request issuance of a portion of the shares in certificated form.
Upon written request from the Planholder,  the Transfer Agent will determine the
number of shares  for which a  certificate  may be issued  without  causing  the
withdrawal checks to stop because of exhaustion of uncertificated  shares needed
to  continue  payments.   However,  should  such  uncertificated  shares  become
exhausted, Plan withdrawals will terminate.
    

      If the Transfer  Agent ceases to act as transfer  agent for the Fund,  the
Planholder will be deemed to have appointed any successor  transfer agent to act
as agent in administering the Plan.

How To Exchange Shares

   
      As stated in the Prospectus,  shares of a particular  class of Oppenheimer
funds having more than one class of shares may be  exchanged  only for shares of
the same class of other Oppenheimer funds.  Shares of the Oppenheimer funds that
have a single class without a class  designation are deemed "Class A" shares for
this purpose.  All of the Oppenheimer funds offer Class A, B and C shares except
Oppenheimer Money Market Fund, Inc.,  Centennial Money Market Trust,  Centennial
Tax Exempt Trust,  Centennial  Government Trust,  Centennial New York Tax Exempt
Trust,  Centennial California Tax Exempt Trust and Centennial America Fund, L.P.
, which  only  offer  Class A shares  and  Oppenheimer  Main  Street  California
Municipal Fund which only offers Class A and Class B shares (Class B and Class C
shares of  Oppenheimer  Cash Reserves are generally  available  only by exchange
from  the  same  class  of  shares  of  other   Oppenheimer   funds  or  through
OppenheimerFunds  sponsored  401 (k) plans).  A current list showing which funds
offer  which  classes  can be  obtained  by calling  the  Distributor  at 1-800-
525-7048.

      For accounts established on or before March 8, 1996 holding Class M shares
of  Oppenheimer  Bond Fund for Growth,  Class M shares can be exchanged only for
Class A shares  of other  Oppenheimer  funds .  Exchanges  to Class M shares  of
Oppenheimer  Bond  Fund  for  Growth  are  permitted  from  Class  A  shares  of
Oppenheimer  Money Market Fund,  Inc. or  Oppenheimer  Cash  Reserves  that were
acquired by exchange from Class M shares. Otherwise no exchanges of any class of
any Oppenheimer fund into Class M shares are permitted.

      Class A shares of  Oppenheimer  funds may be  exchanged at net asset value
for shares of any Money Market Fund.  Shares of any Money Market Fund  purchased
without a sales charge may be exchanged for shares of Oppenheimer  funds offered
with a sales charge upon payment of the sales charge (or, if applicable,  may be
used to purchase  shares of Oppenheimer  funds subject to a contingent  deferred
sales charge).  However, shares of Oppenheimer Money Market Fund, Inc. purchased
with the  redemption  proceeds of shares of other mutual funds (other than funds
managed by the Manager or its subsidiaries)  redeemed within the 12 months prior
to that purchase may  subsequently be exchanged for shares of other  Oppenheimer
funds without being subject to an initial or contingent  deferred  sales charge,
whichever  is  applicable.  To qualify for that  privilege,  the investor or the
investor's  dealer must notify the Distributor of eligibility for this privilege
at the time the shares of  Oppenheimer  Money Market Fund,  Inc. are  purchased,
and, if requested, must supply proof of entitlement to this privilege.

      Shares of the Fund acquired by reinvestment of dividends or  distributions
from any of the other  Oppenheimer  funds or from any unit investment  trust for
which  reinvestment  arrangements  have been made  with the  Distributor  may be
exchanged  at net asset  value for shares of any of the  Oppenheimer  funds.  No
contingent  deferred sales charge is imposed on exchanges of shares of any class
purchased subject to a contingent deferred sales charge.  However,  when Class A
shares  acquired  by  exchange  of Class A shares  of  other  Oppenheimer  funds
purchased  subject to a Class A  contingent  deferred  sales charge are redeemed
within 12 months of the end of the calendar month of the initial purchase of the
exchanged Class A shares (18 months if the shares were initially purchased prior
to May 1, 1997), the Class A contingent  deferred sales charge is imposed on the
redeemed  shares.  (See  "Class  A  Contingent  Deferred  Sales  Charge"  in the
Prospectus).  The Class B contingent deferred sales charge is imposed on Class B
shares  acquired by exchange if they are redeemed  within 6 years of the initial
purchase of the exchanged Class B shares. The Class C contingent  deferred sales
charge is imposed on Class C shares  acquired by  exchange if they are  redeemed
within 12 months of the initial purchase of the exchanged Class C shares.
    

      When Class B or Class C shares are  redeemed  to effect an  exchange,  the
priorities described in "How To Buy Shares" in the Prospectus for the imposition
of the Class B or the Class C contingent  deferred sales charge will be followed
in determining the order in which the shares are exchanged.  Shareholders should
take into  account the effect of any exchange on the  applicability  and rate of
any  contingent  deferred  sales charge that might be imposed in the  subsequent
redemption  of remaining  shares.  Shareholders  owning  shares of more than one
Class must specify  whether they intend to exchange  Class A, Class B or Class C
shares.

      The Fund  reserves  the  right to reject  telephone  or  written  exchange
requests  submitted  in bulk by anyone on behalf of more than one  account.  The
Fund  may  accept  requests  for  exchanges  of up to 50  accounts  per day from
representatives  of  authorized  dealers  that  qualify for this  privilege.  In
connection with any exchange request, the number of shares exchanged may be less
than the number  requested if the exchange or the number requested would include
shares  subject to a restriction  cited in the  Prospectus or this  Statement of
Additional  Information or would include  shares covered by a share  certificate
that is not tendered with the request. In those cases, only the shares available
for exchange without restriction will be exchanged.

      When  exchanging  shares by telephone,  a shareholder  must either have an
existing account in, or have obtained and  acknowledged  receipt of a prospectus
of, the fund to which the exchange is to be made. For full or partial  exchanges
of an account made by  telephone,  any special  account  features  such as Asset
Builder Plans and Automatic Withdrawal Plans will be switched to the new account
unless the Transfer Agent is instructed  otherwise.  If all telephone  lines are
busy (which  might occur,  for example,  during  periods of  substantial  market
fluctuations),  shareholders might not be able to request exchanges by telephone
and would have to submit written exchange requests.

     Shares  to be  exchanged  are  redeemed  on the  regular  business  day the
Transfer  Agent  receives  an exchange  request in proper form (the  "Redemption
Date").  Normally,  shares  of the  fund to be  acquired  are  purchased  on the
Redemption  Date,  but such  purchases  may be delayed by either fund up to five
business days if it determines  that it would be  disadvantaged  by an immediate
transfer  of the  redemption  proceeds.  The Fund  reserves  the  right,  in its
discretion,  to  refuse  any  exchange  request  that may  disadvantage  it (for
example,  if the  receipt of  multiple  exchange  requests  from a dealer  might
require the  disposition  of portfolio  securities  at a time or at a price that
might be disadvantageous to the Fund).

      The different  Oppenheimer  funds  available  for exchange have  different
investment objectives,  policies and risks, and a shareholder should assure that
the Fund selected is  appropriate  for his or her investment and should be aware
of the tax  consequences  of an exchange.  For federal  income tax purposes,  an
exchange  transaction  is  treated as a  redemption  of shares of one fund and a
purchase of shares of another.  "Reinvestment  Privilege," above, discusses some
of the tax  consequences of  reinvestment of redemption  proceeds in such cases.
The  Fund,  the  Distributor,  and the  Transfer  Agent are  unable  to  provide
investment,  tax or legal advice to a shareholder in connection with an exchange
request or any other investment transaction.

Dividends, Capital Gains and Taxes

Dividends and Distributions.  Dividends will be payable on shares held of record
at the time of the previous  determination  of net asset value.  Daily dividends
will not be declared  or paid on newly  purchased  shares  until  Federal  Funds
(funds  credited to a member  bank's  account at the Federal  Reserve  Bank) are
available from the purchase payment for such shares.  Normally,  purchase checks
received from investors are converted to Federal Funds on the next business day.
Shares  purchased  through dealers or brokers normally are paid for by the third
business day  following  the placement of the purchase  order.  Shares  redeemed
through the regular  redemption  procedure  will be paid  dividends  through and
including  the day on which the  redemption  request is received by the Transfer
Agent in proper form.  Dividends will be paid with respect to shares repurchased
by a dealer or broker for three business days following the trade date (i.e., to
and including the day prior to settlement of the  repurchase).  If a shareholder
redeems all shares in an account,  all dividends  accrued on shares held in that
account will be paid together with the redemption proceeds.

      Dividends, distributions and the proceeds of the redemption of Fund shares
represented  by checks  returned to the Transfer  Agent by the Postal Service as
undeliverable will be invested in shares of Oppenheimer Money Market Fund, Inc.,
as promptly as possible  after the return of such checks to the Transfer  Agent,
to enable the investor to earn a return on otherwise idle funds.

   
      The amount of a class's  dividends may vary from time to time depending on
market conditions,  the composition of the Fund's portfolio,  and expenses borne
by the Fund or borne  separately by a class, as described in "Alternative  Sales
Arrangements  -- Class A, Class B and Class C," above.  Dividends are calculated
in the same  manner,  at the same  time and on the same day for  shares  of each
class. However, dividends on Class B and Class C shares are expected to be lower
than dividends on Class A shares as a result of the asset-based sales charges on
Class B and Class C shares,  and will also differ in amount as a consequence  of
any difference in net asset value between the classes.

Tax  Status of the  Fund's  Dividends  and  Distributions.  The Fund  intends to
qualify  under  the  Internal  Revenue  Code  during  each  fiscal  year  to pay
"exempt-interest  dividends" to its  shareholders.  Exempt-  interest  dividends
which are derived  from net  investment  income  earned by the Fund on Municipal
Securities  will be  excludable  from gross income of  shareholders  for Federal
income tax purposes. Net investment income includes the allocation of amounts of
income from the Municipal Securities in the Fund's portfolio which are free from
Federal income taxes.  This allocation will be made by the use of one designated
percentage  applied uniformly to all income dividends made during the Fund's tax
year.  Such  designation  will normally be made following the end of each fiscal
year as to income  dividends  paid in the prior year.  The  percentage of income
designated as tax-exempt  may  substantially  differ from the  percentage of the
Fund's income that was tax-exempt  for a given period.  A portion of the exempt-
interest  dividends  paid  by the  Fund  may be an item  of tax  preference  for
shareholders subject to the alternative minimum tax. All of the Fund's dividends
(excluding  capital  gains  distributions)  paid  during  1997 were  exempt from
Federal personal income taxes.  The amount of any dividends  attributable to tax
preference items for purposes of the alternative  minimum tax will be identified
when tax  information  is distributed by the Fund.  Corporate  shareholders  and
"substantial  users"  of  facilities  financed  by  Private  Activity  Municipal
Securities should see "Private Activity Municipal Securities."

     A shareholder  receiving a dividend from income earned by the Fund from one
or more of: (1) certain taxable  temporary  investments (such as certificates of
deposit,  repurchase  agreements,  commercial  paper and obligations of the U.S.
government,  its agencies  and  instrumentalities);  (2) income from  securities
loans;  or (3) an  excess of net  short-term  capital  gain  over net  long-term
capital loss from the Fund,  treats the dividend as a receipt of ordinary income
in the  computation  of gross  income,  regardless  of whether  the  dividend is
reinvested. The Fund's dividends will not be eligible for the dividends-received
deduction for  corporations.  Shareholders  receiving  Social Security  benefits
should be aware  that  exempt-interest  dividends  are a factor  in  determining
whether such  benefits  are subject to Federal  income tax.  Losses  realized by
shareholders  on the  redemption  of Fund  shares  within six months of purchase
(which period may be shortened by  regulation)  will be  disallowed  for Federal
income tax purposes to the extent of exempt-interest  dividends received on such
shares.     

      Long-term  capital gains  distributions,  if any, are taxable as long-term
capital gains whether  received in cash or reinvested and regardless of how long
Fund  shares  have  been  held.  Dividends  paid by the  Fund  derived  from net
short-term capital gains are taxable to shareholders as ordinary income, whether
received in cash or  reinvested.  For  information  on "backup  withholding"  on
taxable dividends,  see "How To Sell Shares." Interest on loans used to purchase
shares of the Fund may not be deducted for Federal  income tax  purposes.  Under
rules used by the Internal  Revenue Service to determine when borrowed funds are
deemed used for the purpose of purchasing  or carrying  particular  assets,  the
purchase of Fund shares may be considered to have been made with borrowed  funds
even though the  borrowed  funds are not  directly  traceable to the purchase of
shares.

         If the Fund  qualifies as a "regulated  investment  company"  under the
Internal Revenue Code, it will not be liable for Federal income taxes on amounts
paid by it as dividends  and  distributions.  The Fund  qualified as a regulated
investment  company  in its last  fiscal  year and  intends to qualify in future
years, but reserves the right not to qualify. The Internal Revenue Code contains
a number of complex tests to determine  whether the Fund will  qualify,  and the
Fund might not meet those tests in a  particular  year.  If it does not qualify,
the Fund will be treated  for tax  purposes  as an  ordinary  corporation,  will
receive no tax  deduction for payments of dividends  and  distributions  made to
shareholders and would be unable to pay "exempt-interest" dividends as discussed
above.
    

      Under the Internal  Revenue  Code,  by December 31 each year the Fund must
distribute  98% of its taxable  investment  income earned from January 1 through
December  31 of that year and 98% of its  capital  gains  realized in the period
from  November 1 of the prior year through  October 31 of the current  year,  or
else the Fund must pay an excise tax on the amounts not  distributed.  The Board
and the Manager  might  determine in a  particular  year that it might be in the
best  interest of  shareholders  for the Fund not to make  distributions  at the
required  levels and to pay the excise tax on the  undistributed  amounts.  That
would reduce the amount of income or capital gains available for distribution to
shareholders.

Dividend  Reinvestment  in Another Fund.  Shareholders  of the Fund may elect to
reinvest all dividends  and/or  distributions in shares of the same class of any
of the other  Oppenheimer funds (other than Oppenheimer Cash Reserves) listed in
"Reduced  Sales  Charges,"  above,  at net asset value without sales charge.  To
elect this option,  a shareholder  must notify the Transfer Agent in writing and
either must have an existing account in the fund selected for investment or must
obtain a prospectus  for that fund and an  application  from the  Distributor to
establish  an account.  The  investment  will be made at the net asset value per
share in effect at the close of business on the payable  date of the dividend or
distribution.  Dividends  and  distributions  from other  Eligible  Funds may be
invested in shares of this Fund on the same basis.

Additional Information About the Fund

The  Custodian.  Citibank,  N.A.  is the  Custodian  of the Fund's  assets.  The
Custodian's  responsibilities  include  safeguarding  and controlling the Fund's
portfolio securities, collecting income on the portfolio securities and handling
the  delivery  of  such  securities  to and  from  the  Fund.  The  Manager  has
represented to the Fund that the banking  relationships  between the Manager and
the Custodian  have been and will continue to be unrelated to and  unaffected by
the relationship between the Fund and the Custodian.  It will be the practice of
the Fund to deal with the  Custodian  in a manner  uninfluenced  by any  banking
relationship  the  Custodian may have with the Manager and its  affiliates.  The
Fund's cash  balances with the Custodian in excess of $100,000 are not protected
by  Federal  Deposit  Insurance.   Such  uninsured  balances  may  at  times  be
substantial.

   
Independent  Auditors.  The  independent  auditors  of the Fund audit the Fund's
financial statements and perform other related audit services.  They also act as
auditors for the Manager and for certain  other funds advised by the Manager and
its affiliates.

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

================================================================================
The Board of Trustees and Shareholders of
Oppenheimer Insured Municipal Fund:

We have audited the accompanying statement of assets and liabilities,  including
the  statement of  investments,  of  Oppenheimer  Insured  Municipal  Fund as of
September 30, 1997, the related statement of operations for the year then ended,
the  statements of changes in net assets for the years ended  September 30, 1997
and  1996  and the  financial  highlights  for the  period  October  1,  1992 to
September 30, 1997. These financial  statements and financial highlights are the
responsibility  of the Fund's  management.  Our  responsibility is to express an
opinion on these  financial  statements  and financial  highlights  based on our
audits.
               We conducted our audits in  accordance  with  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 at September  30, 1997 by  correspondence  with the custodian and brokers;
where  replies 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,   such   financial   statements  and  financial
highlights present fairly, in all material  respects,  the financial position of
Oppenheimer  Insured  Municipal  Fund at September 30, 1997,  the results of its
operations,  the changes in its net assets, and the financial highlights for the
respective  stated  periods,  in conformity with generally  accepted  accounting
principles.

1. For zero coupon bonds,  the interest rate shown is the effective yield on the
date of purchase.  2.  Represents the current  interest rate for a variable rate
bond known as an  "inverse  floater"  which pays  interest at a rate that varies
inversely  with  short-term  interest  rates.  As interest  rates rise,  inverse
floaters produce less current income.  Their price may be more volatile than the
price of a comparable fixed-rate security. Inverse floaters amount to $7,607,938
or 6.70%  of the  Fund's  net  assets  at  September  30,  1997.  3.  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 $2,272,000 or 2.00% of the Fund's net assets, at September 30, 1997.

As of September  30, 1997,  securities  subject to the  alternative  minimum tax
amounted to $21,370,801 or 18.82% of the Fund's net assets.

Notes to Financial Statements
- --------------------------------------------------------------------------------

================================================================================
1. Significant Accounting Policies
Oppenheimer Insured Municipal Fund (the Fund) is a separate series of
Oppenheimer Municipal Fund, 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 maximum current income exempt from
federal income tax for individual investors that is consistent with the
preservation of capital by investing primarily in insured municipal bonds. The
Fund's investment advisor is OppenheimerFunds, Inc. (the Manager). The Fund
offers Class A, Class B and Class C 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.  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.
- --------------------------------------------------------------------------------
Allocation of Income,  Expenses, and Gains and Losses.  Income,  expenses (other
than those  attributable to a specific class) and 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.


                      22 Oppenheimer Insured Municipal 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 and Class C 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 premium  amortization on long-term bonds 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.
               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 September 30, 1997, amounts have been reclassified to reflect a
decrease in undistributed net investment income of $355,343, an increase in
accumulated net realized gain on investments of $651,828, and a decrease in
paid-in capital of $296,485.
- --------------------------------------------------------------------------------
Other. Investment transactions are accounted for on the date the investments are
purchased or sold (trade date).  Original issue discount on securities purchased
is amortized  over the life of the  respective  securities  using the  effective
yield method,  in accordance  with federal  income tax  requirements.  For bonds
acquired  after April 30, 1993, on  disposition  or maturity,  taxable  ordinary
income is recognized to the extent of the lesser of gain or market discount that
would  have  accrued  over the  holding  period.  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.

================================================================================
For the year ended  September  30,  1997,  commissions  (sales  charges  paid by
investors)  on sales of Class A shares  totaled  $164,201,  of which $35,272 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 $222,466 and $18,115,  respectively,  of which $2,152 and
$1,686,  respectively,  was paid to an affiliated  broker/dealer for Class B and
Class C  shares.  During  the year  ended  September  30,  1997,  OFDI  received
contingent  deferred sales charges of $53,881 upon redemption of Class B 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 maintaining  accounts
of their customers that hold Class A shares. During the year ended September 30,
1997, OFDI paid $9,873 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 services and 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 shares
and Class C shares,  as  compensation  for sales  commissions  paid from its own
resources at the time of sale and associated financing costs. OFDI also receives
a service fee of 0.25% per year as compensation for costs incurred in connection
with the personal  service and  maintenance  of accounts that hold shares of the
Fund,  including  amounts paid to brokers,  dealers,  banks and other  financial
institutions. Both fees are 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 year ended  September  30, 1997,  OFDI paid $2,397,  to an affiliated
broker/dealer  as  compensation  for Class B personal  service  and  maintenance
expenses and retained  $141,004 and $12,061,  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 September 30, 1997,
OFDI had incurred  unreimbursed expenses of $695,667 for Class B and $36,319 for
Class C.

================================================================================
5. 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.
               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.

================================================================================
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  OppenheimerFunds  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
September 30, 1997.



   
                        APPENDIX A

      Descriptions of Ratings Categories

 Municipal Bonds

      |X| Moody's  Investor  Services,  Inc.  The  ratings of Moody's  Investors
Service,  Inc.  ("Moody's") for Municipal Bonds are Aaa, Aa, A, Baa, Ba, B, Caa,
Ca and C.  Municipal  Bonds rated "Aaa" are judged to be of the "best  quality."
The  rating  of Aa is  assigned  to  bonds  which  are of "high  quality  by all
standards,"  but as to  which  margins  of  protection  or other  elements  make
long-term risks appear somewhat  larger than "Aaa" rated  Municipal  Bonds.  The
"Aaa" and "Aa" rated  bonds  comprise  what are  generally  known as "high grade
bonds."  Municipal  Bonds which are rated "A" by Moody's  possess many favorable
investment  attributes  and are  considered  "upper  medium grade  obligations."
Factors  giving  security  to  principal  and  interest  of A  rated  bonds  are
considered adequate,  but elements may be present which suggest a susceptibility
to  impairment  at some time in the  future.  Municipal  Bonds  rated  "Baa" are
considered  "medium grade"  obligations.  They are neither highly  protected nor
poorly secured. Interest payments and principal security appear adequate for the
present   but   certain   protective   elements   may  be   lacking  or  may  be
characteristically  unreliable  over any great  length of time.  Such bonds lack
outstanding   investment   characteristics   and  in   fact   have   speculative
characteristics  as  well.  Bonds  which  are  rated  "Ba"  are  judged  to have
speculative elements;  their future cannot be considered as well assured.  Often
the  protection  of interest and  principal  payments  may be very  moderate and
thereby  not well  safeguarded  during  both good and bad times over the future.
Uncertainty of position characterizes bonds in this class. Bonds which are rated
"B" generally lack  characteristics  of the desirable  investment.  Assurance of
interest and principal payments or of maintenance of other terms of the contract
over any long  period of time may be small.  Bonds  which are rated "Caa" are of
poor standing. Such issues may be in default or there may be present elements of
danger  with  respect  to  principal  or  interest.  Bonds  which are rated "Ca"
represent  obligations  which are speculative in a high degree.  Such issues are
often in default or have other  marked  shortcomings.  Bonds which are rated "C"
are the lowest  rated  class of bonds,  and issues so rated can be  regarded  as
having extremely poor prospects of ever attaining any real investment  standing.
Those bonds in the Aa, A, Baa, Ba and B groups which  Moody's  believes  possess
the strongest  investment  attributes are  designated  Aa1, A1, Baa1, Ba1 and B1
respectively.

      In addition to the alphabetic  rating system  described  above,  Municipal
Bonds rated by Moody's which have a demand feature that provides the holder with
the ability to  periodically  tender  ("put") the portion of the debt covered by
the demand  feature,  may also have a short-term  rating assigned to such demand
feature.   The   short-term   rating  uses  the  symbol   VMIG  to   distinguish
characteristics  which include  payment upon periodic demand rather than fund or
scheduled maturity dates and potential reliance upon external liquidity, as well
as other  factors.  The highest  investment  quality is designated by the VMIG 1
rating and the lowest by VMIG 4.

      |X|  Standard  & Poor's  Corporation.  The  ratings  of  Standard & Poor's
Corporation  ("S&P") for Municipal  Bonds are AAA (Prime),  AA (High  Grade),  A
(Good Grade),  BBB (Medium  Grade),  BB, B, CCC, CC, and C (speculative  grade).
Bonds rated in the top four categories  (AAA, AA, A, BBB) are commonly  referred
to as "investment  grade."  Municipal  Bonds rated AAA are  "obligations  of the
highest   quality."  The  rating  of  AA  is  accorded  issues  with  investment
characteristics  "only  slightly  less  marked  than those of the prime  quality
issues." The rating of A describes "the third strongest  capacity for payment of
debt  service."  Principal  and interest  payments on bonds in this category are
regarded as safe. It differs from the two higher ratings  because,  with respect
to  general  obligations  bonds,  there is some  weakness,  either  in the local
economic base, in debt burden, in the balance between revenues and expenditures,
or in quality of management.  Under certain adverse circumstances,  any one such
weakness might impair the ability of the issuer to meet debt obligations at some
future date. With respect to revenue bonds , debt service  coverage is good, but
not  exceptional.  Stability of the pledged  revenues could show some variations
because of increased  competition  or economic  influences  on  revenues.  Basic
security  provisions,  while  satisfactory,   are  less  stringent.   Management
performance appears adequate.
    


The BBB rating is the lowest  "investment grade" security rating. The difference
between A and BBB  ratings  is that the latter  shows more than one  fundamental
weakness, or one very substantial fundamental weakness, whereas the former shows
only one deficiency among the factors considered. With respect to revenue bonds,
debt  coverage  is only  fair.  Stability  of the  pledged  revenues  could show
variations, with the revenue flow possibly being subject to erosion over time.
 Basic security provisions are no more
   
than adequate.  Management performance could be stronger.  Bonds rated "BB" have
less near-term  vulnerability to default than other speculative issues. However,
it faces major ongoing uncertainties or exposure to adverse business, financial,
or economic  conditions  which would lead to inadequate  capacity to meet timely
interest and principal payments. Bonds rated "B" have a greater vulnerability to
default,  but currently has the capacity to meet interest payments and principal
repayments.  Adverse  business,  financial,  or economic  conditions will likely
impair capacity or willingness to pay interest and repay principal.  Bonds rated
"CCC" have a current  identifiable  vulnerability  to default,  and is dependent
upon  favorable  business,  financial,  and economic  conditions  to meet timely
payment  of  interest  and  repayment  of  principal.  In the  event of  adverse
business,  financial,  or  economic  conditions,  it is not  likely  to have the
capacity to pay interest and repay  principal.  Bonds noted "CC"  typically  are
debt  subordinated  to senior debt which is assigned on actual or implied  "CCC"
debt rating.

      Bonds rated "C"  typically are debt  subordinated  to senior debt which is
assigned an actual or implied "CCC-" debt rating.  The "C" rating may be used to
cover a situation where a bankruptcy  petition has been filed,  but debt service
payments are continued.  Bonds rated "D" are in payment default.  The "D" rating
category is used when  interest  payments or principal  payments are not made on
the date due even if the  applicable  grace period has not  expired,  unless S&P
believes that such payments will be made during the grace period. The "D" rating
also  will be used upon the  filing of a  bankruptcy  petition  if debt  service
payments  are  jeopardized.  The  ratings  from AA to CCC may be modified by the
addition  of a plus or minus  sign to show  relative  standing  within the major
rating categories.

      |X| Fitch.  The ratings of Fitch  Investors  Service,  Inc. for  Municipal
Bonds are AAA, AA, A, BBB, BB, B, CCC,  CC, C, DDD, DD, and D.  Municipal  Bonds
rated AAA are judged to be of the "highest credit  quality." The rating of AA is
assigned to bonds of "very high credit quality." Municipal Bonds which are rated
A by Fitch are  considered to be of "high credit  quality." The rating of BBB is
assigned to bonds of  "satisfactory  credit  quality." The A and BBB rated bonds
are more  vulnerable to adverse  changes in economic  conditions than bonds with
higher  ratings.  Bonds  rated  AAA,  AA,  A and  BBB  are  considered  to be of
investment  grade  quality.  Bonds  rated  below  BBB  are  considered  to be of
speculative  quality.  The ratings of "BB" is assigned  to bonds  considered  by
Fitch to be "speculative."  The rating of "B" is assigned to bonds considered by
Fitch to be "highly  speculative."  Bonds rated "CCC" have certain  identifiable
characteristics  which, if not remedied,  may lead to default.  Bonds rated "CC"
are minimally  protected.  Default in payment of interest and/or principal seems
probable  over  time.  Bonds  rated "C" are in  imminent  default  in payment of
interest  or  principal.  Bonds  rated  "DDD",  "DD" and "D" are in  default  on
interest and/or  principal  payments.  DDD represents the highest  potential for
recovery on these bonds, and D represents the lowest potential for recovery.

      o Duff & Phelps.  The ratings of Duff & Phelps are as  follows:  AAA which
are judged to be the "highest credit quality".  The risk factors are negligible,
being only slightly more than for risk-free US Treasury debt. AA+, AA & AA- High
credit  quality  protection  factors  are  strong.  Risk is modest  but may vary
slightly from time to time because of economic conditions.  A+, A & A-Protection
factors are average but  adequate.  However,  risk factors are more variable and
greater in periods of economic stress. BBB+, BBB & BBB- Below average protection
factors but still  considered  sufficient for prudent  investment.  Considerable
variability in risk during economic

cycles.  BB+, BB & BB-  Below
investment grade but deemed to meet obligations when due. Present or prospective
financial  protection  factors  fluctuate  according to industry  conditions  or
company  fortunes.  Overall  quality may move up or down  frequently  within the
category. B+, B & B- Below investment grade and possessing risk that obligations
will not be met when due.  Financial  protection  factors will fluctuate  widely
according to economic  cycles,  industry  conditions  and/or  company  fortunes.
Potential exists for frequent changes in the rating within this category or into
a higher of lower rating  grade.  CCC Well below  investment  grade  securities.
Considerable  uncertainty  exists as to timely payment of principal  interest or
preferred  dividends.  Protection factors are narrow and risk can be substantial
with unfavorable economic industry  conditions,  and/or with unfavorable company
developments.  DD Defaulted  debt  obligations  issuer failed to meet  scheduled
principal and/or interest payments. DP Preferred stock with dividend averages.

Municipal Notes

      |X| Moody's  ratings for state and  municipal  notes and other  short-term
loans are  designated  Moody's  Investment  Grade  ("MIG").  Notes  bearing  the
designation  MIG-1 are of the best  quality,  enjoying  strong  protection  from
established  cash flows of funds for their  servicing  or from  established  and
broad-based  access to the market for financing.  Notes bearing the  designation
"MIG-2" are of high quality with ample  margins of  protection,  although not as
large as notes rated "MIG ." Such  short-term  notes which have demand  features
may also  carry a rating  using the symbol  VMIG as  described  above,  with the
designation  MIG-1/VMIG 1 denoting best quality, with superior liquidity support
in addition to those characteristics attributable to the designation MIG-1.

      |X| S&P's rating for Municipal  Notes due in three years or less are SP-1,
SP-2,  and SP-3.  SP-1  describes  issues  with a very  strong  capacity  to pay
principal  and interest and compares with bonds rated A by S&P; if modified by a
plus sign, it compares with bonds rated
"SP2" AA or AAA by S&P.  SP-2
describes issues with a satisfactory capacity to pay principal and interest, and
compares  with  bonds  rated  BBB by S&P.  SP-3  describes  issues  that  have a
speculative capacity to pay principal and interest.

      |X|  Fitch's  rating for  Municipal  Notes due in three  years or less are
F-1+,  F-1,  F-2,  F-3, F-S and D. F-1+  describes  notes with an  exceptionally
strong credit quality and the strongest  degree of assurance for timely payment.
F-1 describes  notes with a very strong  credit  quality and assurance of timely
payment is only  slightly  less in degree than issues rated F-1+.  F-2 describes
notes with a good credit quality and a satisfactory assurance of timely payment,
but the  margin  of  safety  is not as great  for  issues  assigned  F-1+ or F-1
ratings.  F-3  describes  notes  with  a fair  credit  quality  and an  adequate
assurance of timely  payment,  but  near-term  adverse  changes could cause such
securities to be rated below  investment  grade.  F-S describes  notes with weak
credit quality. Issues rated D are in actual or imminent payment default.

Corporate Debt

      The "other  debt  securities"  included  in the  definition  of  temporary
investments  are  corporate  (as opposed to  municipal)  debt  obligations.  The
Moody's,  S&P and Fitch  corporate  debt ratings shown do not differ  materially
from those set forth above for Municipal Bonds.




Commercial Paper

      |X|  Moody's  The  ratings of  commercial  paper by Moody's  are  Prime-1,
Prime-2,  Prime-3 and Not Prime.  Issuers rated Prime-1 have a superior capacity
for repayment of short-term promissory obligations. Issuers rated Prime-2 have a
strong  capacity for repayment of  short-term  promissory  obligations.  Issuers
rated Prime-3 have an acceptable capacity for repayment of short-term promissory
obligations.  Issuers rated Not Prime do not fall within any of the Prime rating
categories.

      |X| S&P The ratings of  commercial  paper by S&P are A-1,  A-2, A-3, B, C,
and D. A-1  indicates  that the  degree of safety  regarding  timely  payment is
strong. A-2 indicates capacity for timely payment is satisfactory.  However, the
relative degree of safety
is not as high as for issues designated
A-1. A-3 indicates an adequate capacity for timely payments.  They are, however,
more  vulnerable  to the  adverse  effects  of  changes  in  circumstances  than
obligations  carrying  the higher  designations.  B indicates  only  speculative
capacity for timely payment.  C indicates a doubtful capacity for payment.  D is
assigned to issues in default.

      |X| Fitch The  ratings  of  commercial  paper by Fitch are  similar to its
ratings of Municipal Notes, above.

                       TAX-EQUIVALENT YIELDS


   
The equivalent  yield tables below compare  tax-free  income with taxable income
under Federal income tax rates effective January 1, 1997. Federal taxable income
refers to the net  amount  subject to Federal  income tax after  deductions  and
exemptions.  The tables assume that an investor's highest tax bracket applies to
the  change in  taxable  income  resulting  from a switch  between  taxable  and
non-taxable  investments,  that the  investor is not subject to the  Alternative
Minimum Tax, and that state income tax payments are fully deductible for Federal
income tax  purposes.  The income tax brackets are subject to indexing in future
years to reflect  changes in the  Consumer  Price  Index.  The  brackets  do not
reflect the phaseout of itemized  deductions  and personal  exemptions at higher
income  levels,  resulting  in higher  effective  tax  rates and tax  equivalent
yields.

Item 27.   Indemnification
- -------    ---------------

      Reference  is  made  to  Article  VIII  of   Registrant's   Agreement  and
Declaration of Trust filed as Exhibit 24(b)(1) to the Registration Statement and
incorporated herein by reference.

      Insofar as  indemnification  for liabilities  arising under the Securities
Act of 1933 may be permitted to trustees,  officers and  controlling  persons of
Registrant  pursuant to the foregoing  provisions or otherwise,  Registrant  has
been advised that in the opinion of the Securities and Exchange  Commission such
indemnification  is against  public policy as expressed in the Securities Act of
1933  and  is,  therefore,   unenforceable.  In  the  event  that  a  claim  for
indemnification  against such liabilities  (other than the payment by Registrant
of expenses  incurred  or paid by a trustee,  officer or  controlling  person of
Registrant  in the  successful  defense of any action,  suit or  proceeding)  is
asserted by such trustee, officer or controlling person, Registrant will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification  by it is  against  public  policy  as  expressed  in  the
Securities  Act of 1933 and will be governed by the final  adjudication  of such
issue.

  1. Average Annual Total Returns for the Periods Ended 09/30/97:

   The formula for calculating average annual total return is as follows:

   1/number of years = n       {(ERV/P)^n} - 1 = average annual total
return

   Where:  ERV = ending redeemable value of a hypothetical $1,000 payment
                 made at the beginning of the period
           P   = hypothetical initial investment of $1,000

3. Standardized Yield for the 30-Day Period Ended 09/30/97:

     The Fund's  standardized  yields are calculated using the following formula
set forth in the SEC rules:

                           a - b        6
                Yield =  2 { (--------  +  1 )  -  1 }
                              cd or ce


   The symbols above represent the following factors:

     a = Dividends and interest earned during the 30-day period.
     b = Expenses accrued for the period (net of any expense
          reimbursements).
     c    = The  average  daily  number of Fund  shares  outstanding  during the
          30-day period that were entitled to receive dividends.
     d    = The Fund's maximum offering price (including sales charge) per share
          on the last day of the period.
     e    = The Fund's net asset  value  (excluding  contingent  deferred  sales
          charge) per share on the last day of the period.

Class A Shares

  Dividend Yield        ($0.0743000  *  12 )  /  $18.45  =  4.83%
  at Maximum Offer:


  Dividend Yield        ($0.07430000  *  12 )  / $17.57 =  5.07%
  at Net Asset Value:


  Class B Shares

  Dividend Yield        ($0.0631098  *  12 )  /  $17.58  =  4.31%

   The symbols above represent the following factors:

   a = 30-day SEC yield of tax-exempt  security positions in the portfolio.  b =
   30-day SEC yield of taxable security  positions in the portfolio.  c = Stated
   federal income rate for an individual in the 39.6% federal
       tax bracket filing singly).
