The Fund's Objective and Investment Strategies

What Does the Fund  Invest  In?  The Fund  normally  invests at least 80% of its
total assets in investment-grade municipal securities.  These securities include
municipal bonds (which are debt  obligations  having a maturity of more than one
year when  issued),  municipal  notes  (short term  obligations),  interests  in
municipal leases, and tax-exempt commercial paper. "Investment-grade" securities
are securities  rated in the four highest rating  categories of national  rating
organizations such as Moody's Investors Services or unrated securities judged by
he Fund's  investment  Manager,  OppenheimerFunds,  Inc.,  to be  comparable  to
securities rated as investment grade.

      The  Fund  seeks to  maintain  an  average  effective  portfolio  duration
(measured on a  dollar-weighted  basis) of more than 4.5 years but not more than
8.0 years to try to  reduce  the  volatility  of the  values  of its  securities
portfolio.  However,  the  Fund  can  invest  in  securities  that  have  short,
intermediate or long  maturities.  Because of events  affecting the bond markets
and interest  rate changes,  the duration of the  portfolio  might not meet that
target at all times.

      The  Fund  can  also  use  hedging   instruments  and  certain  derivative
investments to a limited extent to try to manage duration and investment  risks.
These  investments are more fully  explained in "About the Fund's  Investments,"
below.

      |X| How  Does the  Manager  Decide  What  Securities  to Buy or  Sell?  In
selecting  securities for the Fund, the Manager  currently looks  nationwide for
municipal  securities by  considering a variety of factors which may change over
time and may vary in particular  cases.  Currently the Fund's portfolio  manager
looks for:

      |_|      Securities that offer high income,

      |_|      A wide range of issuers  and  securities  to provide  portfolio
diversification,

      |_|      Securities having investment-grade credit characteristics, and

      |_|      Special  situations  among  issuers that provide  opportunities
for value.

Who Is the Fund Designed For? The Fund is designed for investors who are seeking
income  exempt from federal  income  taxes.  It does not seek  capital  gains or
growth. Because it invests in tax-exempt securities, the Fund is not appropriate
for retirement plan accounts or for investors who want to pursue capital growth.


Main Risks of Investing in the Fund

All investments carry risks to some degree.  For bond funds one risk is that the
market prices of the fund's  investments  will fluctuate  when general  interest
rates change (this is known as "interest  rate risk").  Another risk is that the
issuer of the bond will experience financial difficulties and may default on its
obligation 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.

      These risks  collectively form the risk profile of the Fund and can affect
the value of the Fund's investments,  its investment performance, and the prices
of its  shares.  These  risks mean that you can lose money by  investing  in the
Fund. When you redeem your shares,  they may be worth more or less than what you
paid for them.

      The Fund's Manager tries to reduce risks by diversifying  investments,  by
carefully researching  securities before they are purchased and in some cases by
using  hedging  techniques.  However,  changes in the overall  market  prices of
municipal  securities  and the income they pay can occur at any time.  The yield
and share price of the Fund will change daily based on changes in interest rates
and market  conditions,  and in response to other economic  events.  There is no
assurance that the Fund will achieve its investment objective.

An  investment  in the Fund is not a deposit of any bank,  and is not insured or
guaranteed by the Federal Deposit Insurance  Corporation or any other government
agency.

      |X| Credit Risk.  Municipal  securities are subject to credit risk. Credit
risk  relates  to the  ability  of the issuer of a  municipal  security  to make
interest  and  principal  payments  on the  security  as they become due. If the
issuer fails to pay  interest,  the Fund's  income might be reduced,  and if the
issuer fails to repay  principal,  the value of that  security and of the Fund's
shares  might be  reduced.  To help reduce  credit  risks,  the Fund  focuses on
investing  in  investment-grade  securities.  However,  credit  ratings  are not
guarantees of an issuer's timely payments of its obligations.

      |X| Interest Rate Risks. In addition to credit risks, municipal securities
are subject to changes in value when  prevailing  interest  rates  change.  When
interest rates fall, the values of outstanding  municipal  securities  generally
rise,  and the bonds may sell for more than their  face  amount.  When  interest
rates rise, the values of outstanding  municipal  securities generally fall, and
the bonds may sell at a discount from their face amount.

The magnitude of these price changes is generally  greater for bonds with longer
maturities  and  durations.  Although the Fund  attempts to limit its  effective
average  portfolio  duration  to not  more  than 8  years,  the  Fund  can  hold
securities  having  maturities of more than 8 years to seek higher income.  When
the Fund  holds  securities  with long  maturities,  it will seek to manage  its
average portfolio's duration with other investment techniques.  When the average
duration of the Fund's  portfolio is longer,  its share price may fluctuate more
when interest rates change.  However,  the Fund's duration  management  strategy
could be unsuccessful,  so that the prices of its portfolio  securities could be
more volatile than anticipated.

      |X| There Are Special Risks in Using Derivative Investments.  The Fund can
use derivatives to seek increased  returns or to try to hedge investment  risks.
In general terms, a derivative  investment is an investment contract whose value
depends on (or is derived from) the value of an underlying asset,  interest rate
or index.  Options,  futures,  "inverse  floaters"  and interest  rate swaps are
examples of derivatives the Fund can use.

      If the issuer of the  derivative  investment  does not pay the amount due,
the Fund can lose money on its  investment.  Also,  the  underlying  security or
investment on which the derivative is based,  and the derivative  itself,  might
not perform the way the Manager  expected it to perform.  If that  happens,  the
Fund will get less income than  expected or its share price could  decline.  The
Fund has limits on the amount of particular  types of  derivatives  it can hold.
However,  using  derivatives can cause the Fund to lose money on its investments
and/or increase the volatility of its share prices.

How Risky Is the Fund Overall?  The value of the Fund's investments in municipal
securities  will  change  over time due to a number  of  factors.  They  include
changes in general  bond  market  movements,  the change in value of  particular
bonds  because of an event  affecting the issuer,  or changes in interest  rates
that can affect bond prices  overall.  These changes can affect the value of the
Fund's  investments  and its price per share.  While the Fund's goal of managing
the  volatility  of its portfolio by limiting its  affective  average  portfolio
duration may help reduce  fluctuations in the Fund's share price,  unanticipated
events can affect the  duration  of bonds and reduce the  effectiveness  of that
strategy. The Fund can invest in derivative  investments.  These have additional
risks  and  can  cause   fluctuations  in  the  Fund's  share  prices.   In  the
OppenheimerFunds  spectrum,  the Fund is more  conservative  than some  types of
taxable  bond funds,  such as high yield bond funds,  but more  aggressive  than
money market funds.

The Fund's Past Performance

The bar chart and table below show one measure of the risks of  investing in the
Fund, by showing changes in the Fund's performance (for its Class A shares) from
year to year for the last ten  calendar  years and by  showing  how the  average
annual  total  returns of the Fund's  shares  compare to those of a  broad-based
market index.  The Fund's past  investment  performance  is not  necessarily  an
indication of how the Fund will perform in the future.

[see appendix to the  prospectus  for data in bar chart  showing  annual total
returns.]

Sales charges are not included in the  calculations of return in this bar chart,
and if those charges were included, the returns would be less than those shown.

During the  10-year  period  shown in the bar chart,  the  highest  return  (not
annualized)  for a calendar  quarter was 6.06% (2nd Q '89) and the lowest return
for a calendar quarter (not annualized) was -4.59% (1st Q '94).

The Fund's  average  annual total  returns in the table  include the  applicable
sales charge:  for Class A, the current  maximum  initial sales charge of 3.50%;
for Class B, the applicable contingent deferred sales charges of 4% (1-year) and
2.0% (life of class);  for Class C, the 1% contingent  deferred sales charge for
the 1-year period.

The returns  measure the  performance of a hypothetical  account and assume that
all dividends and capital gains distributions have been reinvested in additional
shares.  Because  the Fund  invests in a variety of  municipal  securities,  the
Fund's  performance is compared to the Lehman Brothers  Municipal Bond Index, an
unmanaged  index of a broad range of investment  grade municipal bonds that is a
measure of the  performance of the general  municipal bond market.  However,  it
must be remembered that the index  performance  does not consider the effects of
transaction  costs  and that  the  Fund's  investments  are not  limited  to the
securities in the index.

Fees and Expenses of the Fund

The Fund pays a variety of  expenses  directly  for  management  of its  assets,
administration,  distribution of its shares and other  services.  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
the fees and  expenses  you may pay if you buy and hold shares of the Fund.  The
numbers  below are based on the Fund's  expenses  during  the fiscal  year ended
September 30, 1998.

Expenses may vary in future years. "Other expenses" include transfer agent fees,
custodial fees, and accounting and legal expenses the Fund pays.

Examples.  These examples are intended to help you compare the cost of investing
in the Fund with the cost of  investing  in other  mutual  funds.  The  examples
assume  that you  invest  $10,000  in a class of shares of the Fund for the time
periods indicated, and reinvest your dividends and distributions.

The first example assumes that you redeem all of your shares at the end of those
periods.  The second  example  assumes you keep your shares.  Both examples also
assume  that  your  investment  has a 5% return  each year and that the  class's
operating  expenses  remain the same.  Your actual  costs may be higher or lower
because expenses will vary over time.  Based on these  assumptions your expenses
would be as follows:

  -----------------------------------------------------------------------------
  If shares are redeemed:       1 year      3 years     5 years    10 years1
  -----------------------------------------------------------------------------
  -----------------------------------------------------------------------------
  Class A Shares                $443        $639        $852       $1,464

  -----------------------------------------------------------------------------
  -----------------------------------------------------------------------------
  Class C Shares                $172        $533        $918       $1,998
  -----------------------------------------------------------------------------

In the first example,  expenses include the initial sales charge for Class A and
the applicable  Class B or Class C contingent  deferred  sales  charges.  In the
second example,  the Class A expenses include the sales charge,  but Class B and
Class C expenses do not include contingent deferred sales charges.

1. Class B expense for years 7 through 10 are based on Class A  expenses,  since
Class B shares automatically convert to Class A after 6 years.

About the Fund's Investments

The Fund's Principal Investment Policies. The allocation of the Fund's portfolio
among the different  types of investments the Fund is permitted to buy will vary
over time based on the Manager's  evaluation of economic and market  conditions.
The Fund's  portfolio  might not always  include all of the  different  types of
investments  described below. The Statement of Additional  Information  contains
more detailed information about the Fund's investment policies and risks.

      |X| What  Municipal  Securities  Does the Fund  Invest  In?  The Fund buys
municipal  bonds  and  notes,  tax-exempt  commercial  paper,   certificates  of
participation  in municipal  leases and other debt  obligations.  These are debt
obligations  issued by the governments of states,  their political  subdivisions
(such as cities,  towns and  counties),  the District of  Columbia,  or by their
agencies,  instrumentalities  and  authorities,  if  the  interest  paid  on the
security is not subject to Federal  individual income tax in the opinion of bond
counsel to the issuer at the time the security is issued.  The Fund can also buy
securities issued by any commonwealths, territories or possessions of the United
States, or their respective agencies,  instrumentalities or authorities,  if the
interest  paid on the security is not subject to Federal  individual  income tax
(in the  opinion  of bond  counsel  to the  issuer at the time the  security  is
issued).  All of these types of debt  obligations  are referred to as "municipal
securities" in this prospectus.

      Municipal  securities are issued to raise money for a variety of public or
private  purposes,  including  financing  state or local  governments,  specific
projects or public facilities.  The Fund can invest in municipal securities that
are "general  obligations,"  secured by the  issuer's  pledge of its full faith,
credit and taxing power for the payment of principal and interest.

      The Fund can also buy  "revenue  obligations,"  whose  interest is payable
only  from  the  revenues  derived  from  a  particular  facility  or  class  of
facilities,  or a specific  excise tax or other  revenue  source.  Some of these
revenue  obligations are private  activity bonds that pay interest that may be a
tax preference for investors subject to alternative minimum tax.

      |X| What Does the  "Duration"  of the Fund's  Portfolio  Mean?  "Effective
portfolio  duration" refers to the expected  percentage change in the value of a
debt security  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  in value by 3%.  The
"maturity" of a security (the date when its principal  repayment is due) differs
from effective duration,  which attempts to measure the expected volatility of a
security's price.

      The Fund measures the duration of its entire portfolio of securities, on a
dollar-weighted  basis, to try to maintain an effective  average duration of its
portfolio between 4.5 and 8 years, under normal market conditions (that is, when
financial markets are not in an unstable to volatile state).  However,  duration
cannot be  relied on as an  prediction  of  future  volatility.  There can be no
assurance  that the Fund will  achieve its  targeted  portfolio  duration at all
times.

      Duration  calculations rely on a number of assumptions and variables based
on the historic  performance of similar securities.  Therefore,  duration can be
affected by unexpected  economic  events or conditions  relating to a particular
security, and in times of great market volatility,  the duration calculation for
a security might not be correct.

      |X| Ratings of Municipal  Securities  the Fund Buys.  Under normal  market
conditions, the Fund will invest at least 80% of its total assets in "investment
grade"  municipal  securities.  "Investment  grade"  securities  are those rated
within the four highest rating categories of Moody's,  Standard & Poor's,  Fitch
or Duff & Phelps or another nationally  recognized rating  organization,  or (if
unrated)  judged  by  the  Manager  to be  comparable  to  securities  rated  as
investment grade. Rating categories are described in Appendix A to the Statement
of  Additional  Information.  If  securities  the Fund buys are not  rated,  the
Manager  will use its judgment to assign a rating  category  that it believes is
equivalent to that of a rating agency.

      The  Manager  relies  to some  extent  on  credit  ratings  by  nationally
recognized rating agencies in evaluating the credit risk of securities  selected
for the Fund's portfolio. It also uses its own research and analysis to evaluate
risks. Many factors affect an issuer's ability to make timely payments,  and the
credit risks of a particular security might change over time. A reduction in the
rating of a  security  after  its  purchase  by the Fund will not  automatically
require the Fund to dispose of that security. However, the Manager will evaluate
those securities to determine whether to keep them in the Fund's portfolio.

      |_| Special Credit Risks of Lower-Grade Securities.  Lower-grade municipal
securities usually offer higher yields than investment grade securities buy they
are  subject  to  greater  market  fluctuations  and risks of loss of income and
principal than investment  grade municipal  securities.  Securities that are (or
that have fallen) below investment grade have a greater risk that the issuers of
those securities might not meet their debt  obligations.  However,  limiting its
investments in non-investment grade municipal securities to not more than 20% of
its total assets, helps the Fund reduce the effect of some of these risks on its
share price and income.

      |X| Municipal Lease  Obligations.  Municipal  leases are used by state and
local  government  authorities  to obtain  funds to acquire  land,  equipment or
facilities.  The Fund may invest in certificates of participation that represent
a proportionate interest in payments made under municipal lease obligations.  If
the government  stops making payments or transfers its payment  obligations to a
private entity, the obligation could lose value or become taxable. Some of these
obligations  might not have an active trading market and would be subject to the
fund's limits on "illiquid" securities described below.

      |X| Can the Fund's  Investment  Objective and Policies Change?  The Fund's
Board of  Trustees  can  change  non-fundamental  policies  without  shareholder
approval,  although  significant changes will be described in amendments to this
Prospectus.  Fundamental  policies are those that cannot be changed  without the
approval  of a majority  of the Fund's  outstanding  voting  shares.  The Fund's
investment  objective is a  fundamental  policy.  The  Statement  of  Additional
Information  lists investment  restrictions  that are fundamental  policies.  An
investment policy is not fundamental  unless this Prospectus or the Statement of
Additional Information says that it is.

Other Investment  Strategies.  To seek its objective,  the Fund can also use the
investment  techniques and  strategies  described  below.  The Manager might not
always use all of the different  types of techniques and  investments  described
below. These techniques involve certain risks although some of them are designed
to help reduce investment or market the risks.

      |X|  Floating  Rate/Variable  Rate  Obligations.  Some  of  the  municipal
securities  the Fund can  purchase  have  variable or floating  interest  rates.
Variable rates are adjustable 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.  These  obligations  may be secured by bank letters of
credit or other credit support arrangements.

        |_| Inverse Floaters Have Special Risks.  Certain types of variable rate
bonds known as "inverse  floaters" pay interest at rates that vary 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.  As interest rates rise, inverse floaters produce
less  current  income,  and their  market  value can  become  volatile.  Inverse
floaters  are a type of  "derivative  security."  Some  have a "cap," so that 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 anticipates that
it will invest no more than 10% of its total assets in inverse floaters.

      |X|  Other  Derivatives.  The  Fund  can also  invest  in other  municipal
derivative  securities  that pay  interest  that  depends on changes in price or
value of an index or  another  investment.  Examples  of those  derivatives  are
interest rate swaps, and futures based on municipal bond indices.

      |X|  "When-Issued"  and  "Delayed-Delivery"  Transactions.  The  Fund  can
purchase municipal  securities on a "when-issued" basis and may purchase or sell
such 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.  The Fund  does  not  intend  to make  such
purchases for speculative  purposes.  During the period between the purchase and
settlement,  no payment is made for the security and no interest  accrues to the
buyer from the  investment.  There is a risk of loss to the Fund if the value of
the security declines prior to the settlement date.

      |X|  Puts  and  Stand-By  Commitments.  The  Fund  can  acquire  "stand-by
commitments" or "puts" with respect to municipal  securities.  These investments
give the Fund the right to sell the  securities  at a set price on demand to the
issuing  broker-dealer or bank. However, a security having this feature may have
a lower interest rate. The Fund will acquire stand-by commitments or puts solely
to enhance portfolio liquidity.

      |X| Illiquid and Restricted Securities.  Under the policies and procedures
established  by the  Fund's  Board  of  Trustees,  the  Manager  determines  the
liquidity 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
precisely 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 can increase that limit to 15%). Certain  restricted  securities that
are eligible for resale to qualified institutional purchasers may not be subject
to that limit.  The Manager  monitors  holdings  of  illiquid  securities  on an
ongoing  basis to determine  whether to sell any  holdings to maintain  adequate
liquidity.

      |X|  Hedging.  The Fund can  purchase  and sell  certain  kinds of futures
contracts,  put and call  options,  and  options  on futures  and  broadly-based
municipal bond indices,  or enter into interest rate swap agreements.  These are
all  referred  to as  "hedging  instruments."  The  Fund  does  not use  hedging
instruments  for  speculative  purposes,  and has limits on the use of them. The
Fund  does  not use  hedging  instruments  to a  substantial  degree  and is not
required to use them in seeking its goal.

      The Fund could buy and sell  options and futures for a number of purposes.
It might do so to try to manage its exposure to the possibility  that the prices
of its  portfolio  securities  may  decline,  or to  establish a position in the
securities   market  as  a  temporary   substitute  for  purchasing   individual
securities.  It might do so to try to manage its  exposure to changing  interest
rates.

      If the  Manager  used a hedging  instrument  at the  wrong  time or judged
market conditions incorrectly,  the strategy could 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,  interest  rate swaps are subject to credit risks and
also to interest  rate risks.  The Fund could be obligated to pay more under its
swap  agreements  than it  receives  under them,  as a result of  interest  rate
changes.  The Fund may not enter into swaps with respect to more than 25% of its
total assets.

Temporary  Defensive  Investments.  The Fund can  invest up to 100% of its total
assets in temporary  defensive  investments from time to time. This could happen
during  periods of volatile or adverse market  conditions.  Generally the Fund's
defensive investments would be short-term municipal securities but could be U.S.
government securities or highly-rated corporate debt securities. The income from
some of those  temporary  defensive  investments  might not be  tax-exempt,  and
therefore  when  making  those  investments  the  Fund  might  not  achieve  its
objective.

      Under  normal  market  conditions,  the Fund can also hold these  types of
investments  for cash  management  purposes (in amounts not exceeding 20% of its
total assets) pending the investment of proceeds from the sale of Fund shares or
portfolio  securities,  or to meet anticipated  redemptions of Fund shares.  The
Fund may  invest up to 20% of its  assets in taxable  investments  under  normal
market conditions.

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

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

How the Fund is Managed

The  Manager.  The  Fund's  investment  Manager,   OppenheimerFunds,   Inc.,  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  Fund's  Board of  Trustees,  under an  Investment  Advisory
Agreement that states the Manager's  responsibilities.  The Agreement lists that
the fees the Fund pays 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 $95 billion as of December 31, 1998,
and with more than 4 million shareholder accounts. The Manager is located at Two
World Trade Center, 34th Floor, New York, New York 10048-0203.

     |X|  Portfolio  Manager.  The  portfolio  manager  of  the  Fund  is  Caryn
Halbrecht,  a Vice  President of the Fund and of the  Manager.  She has been the
person  principally  responsible  for the  day-to-day  management  of the Fund's
portfolio,  since October 18, 1993. Ms.  Halbrecht also serves as an officer and
portfolio managers for other Oppenheimer funds.

      |X| Advisory Fees. Under the Investment Advisory Agreement,  the Fund pays
the Manager an  advisory  fee at an annual  rate which  declines  on  additional
assets as the Fund grows:  0.50% of the first $100 million of average annual net
assets,  0.45% of the next $150 million,  0.425% of the next $250  million,  and
0.40% of  average  annual  net  assets  in excess of $500  million.  The  Fund's
management  fee for its last fiscal year ended  September 30, 1998, was 0.49% of
average annual net assets for each class of shares.

How to Buy Shares

How Are Shares Purchased? You can buy shares several ways -- through any dealer,
broker or  financial  institution  that has a sales  agreement  with the  Fund's
Distributor,  or directly through the Distributor,  or automatically  through an
Asset  Builder  Plan  under  the   OppenheimerFunds   AccountLink  service.  The
Distributor  may  appoint  certain  servicing  agents  to accept  purchase  (and
redemption)  orders.  The Distributor,  in its sole  discretion,  may reject any
purchase order for the Fund's shares.

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

      |X| 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,  we recommend  that you discuss your  investment
with a financial  advisor before you make a purchase to be sure that the Fund is
appropriate for you.

      |X| Buying  Shares by Federal  Funds Wire.  Shares  purchased  through the
Distributor  may be paid for by Federal  Funds wire.  The minimum  investment is
$2,500.  Before  sending  a wire,  call the  Distributor's  Wire  Department  at
1-800-525-7048  to notify the  Distributor of the wire,  and to receive  further
instructions.

      |X| Buying Shares Through OppenheimerFunds  AccountLink. With AccountLink,
shares  are  purchased  for  your  account  on  the  regular  business  day  the
Distributor is instructed by you to initiate the Automated  Clearing House (ACH)
transfer to buy the shares.  You can provide those  instructions  automatically,
under an Asset Builder Plan, described below, or by telephone instructions using
OppenheimerFunds PhoneLink, also described below. Please refer to "AccountLink,"
below for more details.

      |X| Buying Shares Through 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 Asset  Builder  Application  and the
Statement of Additional Information.

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.  Subsequent  purchases of at least $25 can be made by telephone  through
AccountLink.

      |_| The  minimum  investment  requirement  does not  apply to  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 reinvesting  distributions  from unit investment trusts that
have made arrangements with the Distributor.

At What Price Are Shares Sold?  Shares are sold at their offering price (the net
asset value per share plus any initial sales charge that applies).  The offering
price that applies to a purchase  order is based on the next  calculation of the
net asset  value per share  that is made  after  the  Distributor  receives  the
purchase order at its offices in Denver,  Colorado, or after any agent appointed
by the Distributor receives the order and sends it to the Distributor.

      |_| The net asset  value of each class of shares is  determined  as of the
close of The New York  Stock  Exchange,  on each  day the  Exchange  is open for
trading  (referred  to in this  Prospectus  as a "regular  business  day").  The
Exchange  normally  closes at 4:00 P.M., New York time, but may close earlier on
some days. (All references to time in this Prospectus mean "New York time").

      The net asset value per share is  determined  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. To determine net asset value, the Fund's Board of Trustees
has established  procedures to value the Fund's securities,  in general based on
market value. The Board has adopted special  procedures for valuing illiquid and
restricted  securities and obligations for which market values cannot be readily
obtained.

      |_| To receive the offering price for a particular  day, in most cases the
Distributor or its  designated  agent must receive your order by the time of day
The New York Stock Exchange  closes that day. If your order is received on a day
when the  Exchange is closed or after it has closed,  the order will receive the
next offering price that is determined after your order is received.

      |_| If you buy shares through a dealer, your dealer must receive the order
by the close of The New York Stock  Exchange and transmit it to the  Distributor
so that it is received before the  Distributor's  close of business on a regular
business  day  (normally  5:00  P.M.) to  receive  that  day's  offering  price.
Otherwise, the order will receive the next offering price that is determined.

- ------------------------------------------------------------------------------
What Classes of Shares Does the Fund Offer?  The Fund offers  investors  three
different  classes  of  shares.  The  different  classes  of shares  represent
investments in the same  portfolio of securities,  but the classes are subject
to different  expenses and will likely have different  share prices.  When you
buy  shares,  be sure to  specify  the class of  shares.  If you do not choose a
class, your investment will be made in Class A shares.
- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------
      |X|   Class A  Shares.  If you buy Class A  shares,  you pay an  initial
sales  charge  (on  investments  up to $1  million).  The amount of that sales
charge will vary depending on the amount you invest.  The sales charge rates are
listed in "How Can I Buy Class A Shares?" below.
- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------

- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------
      |X|   Class B  Shares.  If you  buy  Class B  shares,  you pay no  sales
charge at the time of purchase,  but you will pay an annual  asset-based sales
charge,  and if you sell your shares within six years of buying them, you will
normally pay a contingent  deferred  sales charge.  That  contingent  deferred
sales charge varies  depending on how long you own your shares,  as described in
"How Can I Buy Class B Shares?" below.
- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------

- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------
      |X|   Class C  Shares.  If you  buy  Class C  shares,  you pay no  sales
charge at the time of purchase,  but you will pay an annual  asset-based sales
charge,  and 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 "How Can
I Buy Class C Shares?" below.
- ------------------------------------------------------------------------------

Which  Class of Shares  Should You  Choose?  Once you decide that the Fund is an
appropriate investment for you, the decision as to which class of shares is best
suited to your needs depends on a number of factors that you should discuss with
your financial advisor. Some 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.
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  discussion  below  is  not  intended  to be  investment  advice  or a
recommendation,  because each investor's financial considerations are different.
You should  review these factors with your  financial  advisor.  The  discussion
below  assumes  that  you will  purchase  only one  class of  shares,  and not a
combination of shares of different classes.

      |X| 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,  compared to the effect over
time of higher class-based expenses on shares of Class B or Class C.

        |_| Investing  for the Short Term.  If you have a relatively  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.  That is  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 as 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.

      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.

        |_|  Investing  for the  Longer  Term.  If you are  investing  less than
$100,000 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
appropriate.

      Of course,  these  examples are based on  approximations  of the effect of
current sales charges and expenses projected over time, and do not detail all of
the  considerations  in  selecting a class of shares.  You should  analyze  your
options carefully with your financial advisor before making that choice.

      |X| Are There  Differences  in Account  Features  That Matter to You? Some
account features (such as checkwriting) may not be available to Class B or Class
C shareholders.  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.  Therefore, you should carefully review how you
plan to use your  investment  account  before  deciding which class of shares to
buy.  Additionally,  the 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
charge  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.

      |X| How Does It Affect  Payments to My Broker?  A  salesperson,  such as a
broker, may receive different  compensation for selling one class of shares than
for selling  another class. It is important to remember that Class B and Class C
contingent  deferred sales charges and  asset-based  sales charges have the same
purpose as the front-end sales charge on sales of Class A shares:  to compensate
the  Distributor  for  commissions and expenses it pays to dealers and financial
institutions for selling shares. The Distributor may pay additional 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.

Special Sales Charge  Arrangements  and Waivers.  Appendix C to the Statement of
Additional  Information  details the  conditions for the waiver of sales charges
that apply in certain  cases,  and the special  sales charge rates that apply to
purchases of shares of the Fund by certain groups, or under specified retirement
plan arrangements or in other special types of transactions.

How Can I Buy 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 other  cases,  reduced
sales  charges may be  available,  as  described  below or in the  Statement  of
Additional Information.  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  or allocated to
your dealer as  commission.  The  Distributor  reserves the right to reallow the
entire  commission to dealers.  The current  sales charge rates and  commissions
paid to dealers and brokers are as follows:

  ----------------------------------------------------------------------------
                            Front-end Sales   Front End Sales   Commission as
                            Charge As a       Charge As a       Percentage
                            Percentage of     Percentage     of of Offering
  Amount of Purchase        Offering Price    Net               Price
                                              Amount Invested
  ----------------------------------------------------------------------------
  ----------------------------------------------------------------------------
  Less than $100,000        3.50%             3.63%             3.00%
  ----------------------------------------------------------------------------
  ----------------------------------------------------------------------------
  $100,000 or more but      3.00%             3.09%             2.50%
  less than $250,000
  ----------------------------------------------------------------------------
  ----------------------------------------------------------------------------
  $250,000 or more but      2.50%             2.56%             2.00%
  less than $500,000
  ----------------------------------------------------------------------------
  ----------------------------------------------------------------------------
  $500,000 or more but      2.00%             2.04%             1.50%
  less than $1 million
  ----------------------------------------------------------------------------

      |X| 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  in an amount equal to 1.0% of purchases of $1 million or more other
than by retirement accounts. That commission will be paid only on purchases that
were not previously subject to a front-end sales charge and dealer commission.

      If you  redeem  any of those  shares  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.  That  sales  charge  will be equal to 1.0% of the  lesser  of (1) the
aggregate  net asset  value of the  redeemed  shares  at the time of  redemption
(excluding  shares  purchased  by  reinvestment  of  dividends  or capital  gain
distributions)  or (2) 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
purchases of Class A shares of all Oppenheimer  funds you made that were subject
to the Class A contingent deferred sales charge.

      In determining  whether a contingent deferred sales charge is payable when
shares are  redeemed,  the Fund will first redeem shares that are not subject to
the sales charge,  including  shares  purchased by reinvestment of dividends and
capital gains.  Then the Fund will redeem other shares in the order in which you
purchased  them.  The  Class A  contingent  deferred  sales  charge is waived in
certain   cases   described  in  Appendix  C  to  the  Statement  of  Additional
Information.

      The Class A contingent  deferred  sales charge is not charged on exchanges
of shares under the Fund's exchange privilege (described below). However, if the
shares acquired by exchange are redeemed within 18 calendar months of the end of
the calendar month in which the exchanged shares were originally purchased, then
the sales charge will apply.

How Can I Reduce Sales Charges for Class A Share Purchases?  You may be eligible
to buy Class A shares at reduced  sales charge rates under the Fund's  "Right of
Accumulation" or a Letter of Intent,  as described in "Reduced Sales Charges" in
the Statement of Additional Information.

      |X| Waivers of Class A Sales  Charges.  The Class A initial and contingent
deferred  sales  charges  are not  imposed  in the  circumstances  described  in
Appendix C to 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 when  purchasing  shares  whether any of the special  conditions
apply.

How Can I Buy 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 5 years of their  purchase,  a contingent  deferred  sales charge will be
deducted from the  redemption  proceeds.  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.

      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
net asset value. The contingent deferred sales charge is not imposed on:

      |_|   the amount of your  account  value  represented  by an increase in
      net asset value over the initial purchase price,

      |_|   shares  purchased  by the  reinvestment  of  dividends  or capital
      gains distributions, or

      |_| shares redeemed in the special  circumstances  described in Appendix C
      to the Statement of Additional Information.

      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 6 years, and

      (3) shares held the longest during the 6-year period.

      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 on
  Years Since Beginning of Month in     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.  In applying the sales charge,  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.  Class B shares automatically
convert to Class A shares 72 months after you  purchase  them.  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 the Statement of Additional Information.

How Can I Buy 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.  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.

      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
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,

o     shares  purchased by the  reinvestment  of  dividends  or capital  gains
         distributions, or
o        shares redeemed in the special circumstances described in Appendix C to
         the Statement of Additional Information.

      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 (12b-1) Plans.

      |X| Service  Plan for Class A Shares.  The Fund has adopted a Service Plan
for Class A shares.  It reimburses  the  Distributor  for a portion of its costs
incurred  for  services   provided  to  accounts   that  hold  Class  A  shares.
Reimbursement  is made quarterly at an annual rate of up to 0.25% of the average
annual net assets of Class A shares of the Fund. The Distributor  currently uses
all  of  those  fees  to  pay  dealers,   brokers,  banks  and  other  financial
institutions  quarterly  for  providing  personal  service  and  maintenance  of
accounts of their customers that hold Class A shares.

      |X|  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 its services and costs in 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.

      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.  Because
these fees are paid out of the Fund's  assets on an  on-going  basis,  over time
these fees will increase the cost of your  investment and may cost you more than
other types of sales charges.

      The Distributor uses the service fees to compensate  dealers for providing
personal  services  for  accounts  that  hold  Class B or  Class C  shares.  The
Distributor pays the 0.25% service fees to dealers in advance for the first year
after the shares were sold by the dealer.  After the shares have been held for a
year, the Distributor pays the service fees to dealers on a quarterly basis.

      The Distributor  currently pays sales  commission 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  therefore
3.00% of the purchase  price.  The  Distributor  retains the Class B asset-based
sales charge.

      The Distributor  currently pays sales commissions of 0.75% of the purchase
price of Class C 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 sale of Class C shares  is  therefore
1.00% of the purchase price. The Distributor  pays 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. Special Investor Services

you to sell shares  automatically  or exchange them to another  OppenheimerFunds
account on a regular  basis.  Please  call the  Transfer  Agent or  consult  the
Statement of Additional Information for details.

Reinvestment  Privilege.  If you  redeem  some or all of your Class A or Class B
shares  of the  Fund,  you have up to 6 months  to  reinvest  all or part of the
redemption  proceeds  in Class A shares of the Fund or other  Oppenheimer  funds
without  paying a sales charge.  This  privilege  applies only to Class A shares
that you purchased  subject to an initial sales charge and to Class A or Class B
shares on which you paid a  contingent  deferred  sales charge when you redeemed
them.  This privilege does not apply to Class C shares.  You must be sure to ask
the Distributor for this privilege when you send your payment.

How to Sell Shares

You can sell  (redeem)  some or all of your shares on any regular  business day.
Your shares will be sold at the next net asset value calculated after your order
is received in proper form (which means that it must comply with the  procedures
described  below) and is accepted by the Transfer Agent.  The Fund lets you sell
your shares by writing a letter, by using the Fund's  checkwriting  privilege or
by telephone. You can also set up Automatic Withdrawal Plans to redeem shares on
a  regular  basis.  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.

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

U.S.  registered  dealer or  broker in  securities,  municipal  securities  or
government   securities,   or  by  a  U.S.  national  securities  exchange,  a

How Do I Sell 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
may be  earlier  on some  days.  You may not  redeem  shares  held under a share
certificate by telephone.

      |_|   To  redeem   shares   through  a  service   representative,   call
1-800-852-8457

      |_|   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 bank account.

Are There Limits on Amounts Redeemed by Telephone?

      |X| 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.

      |X| Telephone Redemptions Through AccountLink.  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.

Checkwriting  Against Your Account.  To write checks  against your Fund account,
request  that  privilege on your  account  Application,  or contact the Transfer
Agent for signature cards.  They 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 other account.

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

      |_| 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.

      |_|   Checks must be written for at least $100.

      |_|   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.

      |_| 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.

      |_| Don't use your checks if you changed your Fund account  number,  until
you receive new checks.

Can I Sell Shares Through My 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.  If your shares are held in the
name of your dealer, you must redeem them through your dealer.

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:

      |_|         Shares of the fund  selected for exchange  must be available
for sale in your state of residence.

      |_| The  prospectuses  of this Fund and the fund whose  shares you want to
buy must offer the exchange privilege.

      |_| 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.

     |_| You  must  meet  the  minimum  purchase  requirements  for the fund you
purchase by exchange.

     |_|  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.  In some
cases, sales charges may be imposed on exchange transactions.  For tax purposes,
exchanges  of  shares  involve  a sale 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.  Please refer to "How to Exchange  Shares" in the  Statement of Additional
Information for more details.

How Do I Submit  Exchange  Requests?  Exchanges may be requested in writing or
by telephone:

      |X|         Written  Exchange  Requests.   Submit  an   OppenheimerFunds
Exchange  Request  form,  signed by all owners of the account.  Send it to the
Transfer  Agent at the  address on the Back  Cover.  Exchanges  of shares held
under certificates  cannot be processed unless the Transfer Agent receives the
certificates with the request.

      |X| 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.

Are There  Limitations on Exchanges?  There are certain exchange  policies you
should be aware of:

      |_| 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 conforms to the policies
described above. It must be received 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
exchange.  For example, the receipt of multiple exchange requests from a "market
timer"  might  require the Fund to sell  securities  at a  disadvantageous  time
and/or price.

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

      |_| 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.

      |_| 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

More  information  about the Fund's policies and procedures for buying,  selling
and exchanging shares is contained in the Statement of Additional Information.

      |X| 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.

      |X|  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 the
Transfer Agent receives cancellation instructions from an owner of the account.

      |X| 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.  The Transfer Agent and the Fund will
not be liable for  losses or  expenses  arising  out of  telephone  instructions
reasonably believed to be genuine.

      |X| 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.

      |X| 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.

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

      |X|  Payment  for  redeemed  shares  ordinarily  is  made in  cash.  It is
forwarded by check or through AccountLink (as elected by the shareholder) within
seven days after the Transfer Agent receives  redemption  instructions in proper
form.  However,  under unusual  circumstances  determined by the  Securities and
Exchange  Commission,   payment  may  be  delayed  or  suspended.  For  accounts
registered  in the name of a  broker-dealer,  payment will normally be forwarded
within three business days after redemption.

      |X| 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 or  certified  check,  or arrange  with your bank to provide
telephone or written  assurance to the Transfer Agent that your purchase payment
has cleared.

      |X|  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. In some cases involuntary redemptions may be
made to repay the Distributor for losses from the cancellation of share purchase
orders.

      |X| Shares may be "redeemed in kind" under unusual  circumstances (such as
a lack of liquidity in the Fund's  portfolio  to meet  redemptions).  This means
that the  redemption  proceeds  will be paid  with  securities  from the  Fund's
portfolio.

      |X|  "Backup  Withholding"  of Federal  income tax may be applied  against
taxable dividends,  distributions and redemption proceeds (including  exchanges)
if you fail to furnish  the Fund your  correct,  certified  Social  Security  or
Employer  Identification  Number  when  you  sign  your  application,  or if you
under-report your income to the Internal Revenue Service.

      |X| 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 and Tax Information

Dividends.  The Fund intends to declare  dividends  separately for each class of
shares from net  tax-exempt  income  and/or net  investment  income each regular
business  day and to pay  those  dividends  to  shareholders  monthly  on a date
selected by the Board of Trustees.  Daily dividends will not be declared or paid
on newly-purchased shares until Federal Funds are available to the Fund from the
purchase payment for such shares.

      The Fund attempts to pay dividends on Class A shares at a constant  level.
There is no  assurance  that it will be able to do so. The Board of Trustees may
change  the  targeted  dividend  level at any  time,  without  prior  notice  to
shareholders.  Dividends and distributions paid on Class A shares will generally
be  higher  than for  Class B and Class C shares,  which  normally  have  higher
expenses than Class A. The Fund cannot  guarantee that it will pay any dividends
or distributions.

Capital  Gains.  Although the Fund does not seek capital  gains,  it may realize
capital  gains  on the sale of  portfolio  securities.  If it does,  it may make
distributions  out of any net short-term or long-term  capital gains in December
of each year.  The Fund may make  supplemental  distributions  of dividends  and
capital gains following the end of its fiscal year. Long-term capital gains will
be separately identified in the tax information the Fund sends you after the end
of the calendar year.

What Choices Do I Have for Receiving Distributions?  When you open your account,
specify  on  your  application  how you  want  to  receive  your  dividends  and
distributions. You have four options:

      |X|         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.

      |X|  Reinvest  Long-Term  Capital  Gains  Only.  You can elect to reinvest
long-term capital gains  distributions in the Fund while receiving  dividends by
check or having them sent to your bank account through AccountLink.

      |X|         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 through AccountLink.

      |X|         Reinvest  Your  Distributions  in  Another  OppenheimerFunds
Account.  You can  reinvest all  distributions  in the same class of shares of
another OppenheimerFunds account you have established.

Taxes. Dividends paid from net investment income earned by the Fund on municipal
securities will be excludable from gross income for Federal income tax purposes.
A portion of a dividend that is derived from  interest paid on certain  "private
activity  bonds"  may be an item of tax  preference  if you are  subject  to the
alternative minimum tax. If the Fund earns interest on taxable investments,  any
dividends  derived  from those  earnings  will be taxable as ordinary  income to
shareholders.

      Dividends and capital gains distributions may be subject to state or local
taxes.  Long-term  capital  gains are taxable as  long-term  capital  gains when
distributed  to  shareholders.  It does not  matter  how long you have held your
shares.  Dividends  paid from  short-term  capital gains and non-tax  exempt net
investment  income are taxable as ordinary  income.  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.

      |X|  Remember,  There May be Taxes on  Transactions.  Even though the Fund
seeks to distribute  tax-exempt  income 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.

      |X|         Returns  of   Capital   Can   Occur.   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.

      This  information  is only a summary of certain  federal  tax  information
about your investment. You should consult with your tax adviser about the effect
of an investment in the Fund on your particular tax situation.

Financial Highlights

The Financial  Highlights  Table is presented to help you  understand the Fund's
financial  performance for the past 5 fiscal years. Certain information reflects
financial  results  for a single  Fund  share.  The total  returns  in the table
represent the rate that an investor would have earned [or lost] on an investment
in the Fund (assuming  reinvestment  of all dividends and  distributions).  This
information has been audited by Deloitte & Touche,  LLP, the Fund's  independent
auditors, whose report, along with the Fund's financial statements,  is included
in the Statement of Additional Information, which is available on request.

ABOUT THE FUND
- ------------------------------------------------------------------------------


Additional Information About the Fund's Investment Policies and Risks

The investment  objective and the principal  investment policies of the Fund are
described in the Prospectus.  This Statement of Additional  Information contains
supplemental  information  about those policies and the types of securities that
the Fund's investment Manager, OppenheimerFunds,  Inc., can select for the Fund.
Additional  explanations are also provided about the strategies the Fund may use
to try to achieve its objective.

The Fund's Investment Policies.  The composition of the Fund's portfolio and the
techniques  and strategies  that the Fund's Manager uses in selecting  portfolio
securities  will  vary over  time.  The Fund is not  required  to use all of the
investment techniques and strategies described below at all times in seeking its
goal. It may use some of the special  investment  techniques  and  strategies at
some times or not at all.

      The Fund does not make  investments  with the objective of seeking capital
growth.  However,  the values of the securities held by the Fund may be affected
by changes in general interest rates and other factors, prior to their maturity.
Because the current  values of debt  securities  vary  inversely with changes in
prevailing  interest  rates,  if  interest  rates  increase  after a security is
purchased,  that  security  will  normally  fall in  value.  Conversely,  should
interest rates  decrease after a security is purchased,  normally its value will
rise.

      However, those fluctuations in value will not generally result in realized
gains or losses to the Fund  unless  the Fund  sells the  security  prior to the
security's  maturity.  A debt  security  held to maturity is  redeemable  by its
issuer at full principal value plus accrued interest.  The Fund does not usually
intend to  dispose  of  securities  prior to their  maturity,  but may do so for
liquidity purposes,  or because of other factors affecting the issuer that cause
the  Manager  to sell the  particular  security.  In that  case,  the Fund could
realize a capital gain or loss on the sale.

      There are variations in the credit quality of municipal  securities,  both
within a particular rating  classification  and between  classifications.  These
variations depend on numerous factors. The yields of municipal securities depend
on a number of factors, including general conditions in the municipal securities
market,  the size of a particular  offering,  the maturity of the obligation and
rating (if any) of the issue.  These  factors are  discussed  in greater  detail
below.

      |X| Portfolio  Turnover.  A change in the securities held by the Fund from
buying and selling  investments  is known as  "portfolio  turnover."  Short-term
trading  increases the rate of portfolio  turnover and could increase the Fund's
transaction  costs.  However,  the Fund ordinarily incurs little or no brokerage
expense because most of the Fund's  portfolio  transactions are principal trades
that do not require payment of brokerage commissions.

The Fund ordinarily does not trade securities to achieve capital gains,  because
they would not be tax-exempt income. To a limited degree, the Fund may engage in
short-term trading to attempt to take advantage of short-term market variations.
It may also do so to dispose of a portfolio security prior to its maturity. That
might be done if, on the basis of a revised  credit  evaluation of the issuer or
other considerations,  the Manager believes such disposition is advisable or the
Fund needs to generate cash to satisfy requests to redeem Fund shares.  In those
cases,  the Fund may  realize a  capital  gain or loss on its  investments.  The
Fund's annual portfolio turnover rate normally is not expected to exceed 100%.

Municipal  Securities.  The types of municipal  securities in which the Fund may
invest are  described in the  Prospectus  under "About the Fund's  Investments."
Municipal  securities  are  generally  classified as general  obligation  bonds,
revenue bonds and notes.  A discussion of the general  characteristics  of these
principal types of municipal securities follows below.

      |X| Municipal  Bonds. We have  classified  municipal  securities  having a
maturity  (when the  security  is  issued)  of more than one year as  "municipal
bonds." The principal  classifications of long-term municipal bonds are "general
obligation" and "revenue" (including  "industrial  development") bonds. They may
have fixed, variable or floating rates of interest, as described below.

            Some bonds may be  "callable,"  allowing  the issuer to redeem  them
before their maturity date. To protect bondholders, callable bonds may be issued
with  provisions  that  prevent  them from  being  called  for a period of time.
Typically,  that is 5 to 10 years from the issuance  date.  When interest  rates
decline,  if the call  protection on a bond has expired,  it is more likely that
the issuer may call the bond.  If that  occurs,  the Fund might have to reinvest
the proceeds of the called bond in bonds that pay a lower rate of return.

        |_|  General   Obligation  Bonds.  The  basic  security  behind  general
obligation  bonds is the issuer's pledge of its full faith and credit and taxing
power,  if any,  for the  repayment  of  principal  and the payment of interest.
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 rate of taxes that can be
levied  for the  payment  of debt  service  on these  bonds  may be  limited  or
unlimited. Additionally, there may be limits as to the rate or amount of special
assessments that can be levied to meet these obligations.

        |_|  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 tax or other
specific  revenue source.  Revenue bonds are issued to finance a wide variety of
capital  projects.  Examples  include  electric,  gas,  water and sewer systems;
highways,  bridges,  and  tunnels;  port and airport  facilities;  colleges  and
universities; and hospitals.

      Although  the  principal  security  for these types of bonds may vary from
bond to bond,  many  provide  additional  security in the form of a debt service
reserve fund that 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.

        |_|  Industrial  Development  Bonds.  Industrial  development  bonds are
considered  municipal  bonds if the interest paid is exempt from federal  income
tax.  They 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 may also be 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 financed by the bond as security
for those payments.

      |_| 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 certain types of municipal securities.  The Tax Reform
Act  generally  did not change  the tax  treatment  of bonds  issued in order to
finance  governmental  operations.  Thus,  interest on general  obligation bonds
issued by or on behalf of state or local governments,  the proceeds of which are
used to finance the operations of such governments,  continues to be tax-exempt.
However,   the  Tax  Reform  Act  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 is
taxable  under  the  revised  rules.  There  is  an  exception  for  "qualified"
tax-exempt private activity bonds, for example,  exempt facility bonds including
certain  industrial  development  bonds,  qualified  mortgage  bonds,  qualified
Section 501(c)(3) bonds, and qualified student loan 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.

      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.  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 Federal alternative minimum tax is designed to ensure that all persons
who receive  income pay some tax,  even if their  regular  tax is zero.  This is
accomplished in part by including in taxable income certain tax preference items
that are used to calculate  alternative  minimum taxable income.  The Tax Reform
Act  made  tax-exempt  interest  from  certain  private  activity  bonds  a  tax
preference item for purposes of the  alternative  minimum tax on individuals and
corporations.  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 the  proportionate  relationship  the interest the investment  company
receives on such bonds bears to all its exempt interest dividends.

      In addition,  corporate  taxpayers subject to the alternative  minimum tax
may,  under some  circumstances,  have to include  exempt-interest  dividends in
calculating  their  alternative  minimum  taxable  income.  That could  occur in
situations where the "adjusted current earnings" of the corporation  exceeds its
alternative minimum taxable income.

      To determine whether a municipal  security is treated as a taxable private
activity  bond,  it is subject to 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 the 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 private loan restriction,  the amount of
bond proceeds that 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 the
use of the bond-financed  facility. The Fund makes no independent  investigation
of the users of such bonds or their use of  proceeds  of the bonds.  If the Fund
should hold a bond that loses its tax-exempt status  retroactively,  there might
be  an  adjustment  to  the   tax-exempt   income   previously   distributed  to
shareholders.

      Additionally,  a private activity bond that 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 applies primarily to exempt
facility bonds,  including industrial  development bonds. The Fund may invest in
industrial  development bonds and other private activity bonds.  Therefore,  the
Fund may not be an appropriate  investment  for entities which are  "substantial
users" (or persons  related to "substantial  users") of such exempt  facilities.
Those entities and persons should consult their tax advisers  before  purchasing
shares of the Fund.

      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 individual or the
individual'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.

      |X| Municipal  Notes.  Municipal  securities  having a maturity  (when the
security  is  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.  Some of the types of municipal  notes the Fund can invest in are
described below.

        |_| Tax Anticipation  Notes. These 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 other business taxes, and
are payable from these specific future taxes.

        |_| Revenue   Anticipation   Notes.   These   are   notes   issued  in
expectation  of receipt of other  types of revenue,  such as Federal  revenues
available under Federal revenue-sharing programs.

        |_| Bond  Anticipation  Notes.  Bond  anticipation  notes are  issued to
provide  interim  financing  until  long-term  financing  can be  arranged.  The
long-term  bonds  that are  issued  typically  also  provide  the  money for the
repayment of the notes.

        |_|  Construction  Loan  Notes.   These  are  sold  to  provide  project
construction   financing  until  permanent  financing  can  be  secured.   After
successful  completion and acceptance of the project,  it may receive  permanent
financing through public agencies, such as the Federal Housing Administration.

      |X|   Tax Exempt Commercial  Paper.  This type of short-term  obligation
(usually  having a maturity  of 270 days or less) is issued by a  municipality
to meet current working capital needs.

      |X| Municipal Lease Obligations. The Fund's investments in municipal lease
obligations  may be through  certificates of  participation  that are offered to
investors by public  entities.  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.

      Some municipal lease securities may be deemed to be "illiquid" securities.
Their  purchase  by the Fund would be limited as  described  below in  "Illiquid
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 Board of Trustees.  Those guidelines  require
the Manager to evaluate:
     |_| the frequency of trades and price quotations for such securities;  
     |_| the number of dealers or other potential  buyers willing to purchase or
sell such securities;
     |_| the availability of market-makers; and
     |_| the nature of the trades for such securities.

            Municipal  leases have special risk  considerations.  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 that purpose on a yearly basis.  While the obligation
might be secured by the lease, it might be difficult to dispose of that property
in case of a default.

      Projects  financed with  certificates of  participation  generally are not
subject to state constitutional debt limitations or other statutory requirements
that may apply to other municipal  securities.  Payments by the public entity on
the obligation  underlying the certificates  are derived from available  revenue
sources.  That  revenue  might 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 a state
or any of its political subdivisions.

      In addition to the risk of "non-appropriation," municipal lease securities
do not have as highly liquid a market as conventional municipal bonds. Municipal
leases,  like  other  municipal  debt  obligations,  are  subject to the risk of
non-payment of interest or repayment of principal by the issuer.  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. A default in
payment of income would  result in a reduction  of income to the Fund.  It could
also result in a reduction in the value of the municipal lease and that, as well
as a default in  repayment of  principal,  could result in a decrease in the net
asset value of the Fund. While the Fund holds such securities,  the Manager will
also evaluate the  likelihood of a continuing  market for these  securities  and
their credit quality.

      |X|  Duration  of the  Fund's  Portfolio.  The  Fund  can  invest  in debt
securities of any maturity or duration but currently has an operating  policy to
maintain a  dollar-weighted  average  effective  portfolio  duration of 4.5 to 8
years.  The goal is to try to manage the sensitivity of the Fund's  portfolio to
changes  in  interest  rates,  and in doing so to manage the  volatility  of the
Fund's share prices in response to those changes. However,  unanticipated events
may  change the  effective  duration  of a security  after the Fund buys it, and
there can be no assurance  that the Fund will  achieve its targeted  duration at
all times.

      The  Manager   determines  the  effective  duration  of  debt  obligations
purchased  by the Fund  considering  various  factors that apply to a particular
type of debt obligation,  including those described below. Duration is a measure
of the expected life of a security on a current-value  basis expressed in years,
using calculations that consider the security's yield, coupon interest payments,
final maturity and call features.

      While a debt security's maturity can be used to measure the sensitivity of
the  security's  price to changes in interest  rates,  the term to maturity of a
security  does not take into  account the pattern (or  expected  pattern) of the
security's payments of interest or principal prior to maturity. Duration, on the
other hand,  measures  the length of the time  interval  from the present to the
time when the interest and principal  payments are scheduled to be received (or,
in the case of a callable  bond,  when the interest  payments are expected to be
received).  Duration calculations weigh them by the present value of the cash to
be received at each future  point in time.  If the  interest  payments on a debt
security occur prior to the repayment of principal, the duration of the security
is less than its stated maturity. For zero-coupon securities,  duration and term
to maturity are equal.

      Absent other factors, the lower the stated or coupon rate of interest on a
debt security or the longer the maturity or the lower the  yield-to-maturity  of
the debt  security,  the longer the duration of the  security.  Conversely,  the
higher the stated or coupon rate of  interest,  the shorter the  maturity or the
higher the yield-to-maturity of a debt security, the shorter the duration of the
security.

      Futures, options and options on futures in general have durations that are
closely  related to the duration of the securities  that underlie them.  Holding
long futures  positions or call option positions  (backed by liquid assets) will
tend to lengthen the portfolio's duration.

      In some  cases  the  standard  effective  duration  calculation  does  not
properly reflect the interest rate exposure of a security. For example, floating
and variable rate securities  often have final  maturities of ten or more years.
However, their exposure to interest rate changes corresponds to the frequency of
the times at which  their  interest  coupon  rate is  reset.  In these and other
similar  situations,  the  Manager  will use other  analytical  techniques  that
consider  the economic  life of the  security as well as relevant  macroeconomic
factors in determining the Fund's effective duration.

      |X| Ratings of Municipal Securities. Ratings by ratings organizations such
as Moody's Investors Service,  Standard & Poor's Ratings Service and Fitch IBCA,
Inc.  represent the respective rating agency's opinions of the credit quality of
the municipal  securities  they  undertake to rate.  However,  their ratings are
general  opinions and are not guarantees of quality.  Municipal  securities that
have the same maturity, coupon and rating may have different yields, while other
municipal  securities  that have the same  maturity  and  coupon  but  different
ratings may have the same yield.

      Subsequent to its purchase by the Fund, a municipal  security may cease to
be rated or its rating may be reduced below the minimum required for purchase by
the Fund. Neither event requires the Fund to sell the security,  but the Manager
will consider  such events in  determining  whether the Fund should  continue to
hold the  security.  To the extent that  ratings  given by  Moody's,  Standard &
Poor's, or Fitch change as a result of changes in those rating  organizations or
their  rating  systems,  the Fund will  attempt  to use  comparable  ratings  as
standards for investments in accordance with the Fund's investment policies.

      The  Fund  can buy  municipal  securities  that  are  "pre-refunded."  The
issuer's  obligation to repay the  principal  value of the security is generally
collateralized with U.S. government securities placed in an escrow account. This
causes the  pre-refunded  security to have essentially the same risks of default
as a AAA-rated security.

      The rating  definitions of Moody's,  Standard & Poor's,  Duff & Phelps and
Fitch for municipal  securities are contained in Appendix A to this Statement of
Additional  Information.  The Fund can purchase  securities  that are unrated by
nationally  recognized  rating  organizations.  The  Manager  will  make its own
assessment of the credit  quality of unrated  issues the Fund buys.  The Manager
will use  criteria  similar to those used by the rating  agencies,  and assign a
rating category to a security that is comparable to what the Manager  believes a
rating agency would assign to that security.  However, the Manager's rating does
not constitute a guarantee of the quality of a particular issue.

      |_| Special Risk of  Lower-Grade  Securities.  Lower grade  securities may
have a higher yield than securities  rated in the higher rating  categories.  In
addition to having a greater risk of default than higher-grade securities, there
may be less of a market for these securities.  As a result they may be harder to
sell at an acceptable  price.  The  additional  risks mean that the Fund may not
receive the anticipated  level of income from these  securities,  and the Fund's
net  asset  value  may be  affected  by  declines  in the  value of  lower-grade
securities.  However,  because the added risk of lower quality  securities might
not be consistent with the Fund's policy of  preservation  of capital,  the Fund
limits its investments in lower quality securities. While securities rated "Baa"
by Moody's or "BBB" by Standard & Poor's or Duff & Phelps are investment  grade,
they may be subject to special risks and have some speculative characteristics.

      Other Investment Techniques and Strategies.  In seeking its objective, the
Fund  may from  time to time  employ  the  types of  investment  strategies  and
investments  described below. It is not required to use all of the strategies at
all times and at times may not use them.

      |X| Floating  Rate and Variable  Rate  Obligations.  Variable  rate demand
obligations  have a demand feature that allows the Fund to tender the obligation
to the issuer or a third party prior to its  maturity.  The tender may be at par
value plus accrued interest, according to the terms of the obligation.

      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 91-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 not less 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 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  those  quality
standards.

      Floating rate and variable  rate demand notes that have a stated  maturity
in excess of one year may have  features  that  permit the holder to recover the
principal amount of the underlying security at specified intervals not exceeding
one year and upon not more than 30 days' notice. The issuer of that type of note
normally has a corresponding  right in its discretion,  after a given period, to
prepay  the  outstanding  principal  amount of the note plus  accrued  interest.
Generally  the issuer  must  provide a specified  number of days'  notice to the
holder.

      |X| Inverse  Floaters and Other Derivative  Investments.  Inverse floaters
may  offer  relatively  high  current  income,  reflecting  the  spread  between
long-term and short-term  tax exempt  interest  rates.  As long as the municipal
yield curve remains relatively steep and short-term rates remain relatively low,
owners  of  inverse  floaters  will have the  opportunity  to earn  interest  at
above-market  rates because they receive  interest at the higher long-term rates
but have paid for bonds with lower short-term rates. If the yield curve flattens
and shifts  upward,  an inverse  floater  will lose  value more  quickly  than a
conventional  long-term  bond. The Fund will invest in inverse  floaters to seek
higher  tax-exempt  yields than are available  from  fixed-rate  bonds that have
comparable maturities and credit ratings. In some cases the holder of an inverse
floater may have an option to convert the floater to a fixed-rate bond, pursuant
to a "rate-lock option."

      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  fluctuations.
"Embedded"  caps can be used to hedge a portion of the Fund's exposure to rising
interest  rates.  When  interest  rates exceed a  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.

      Inverse floaters are a form of derivative investment. Certain derivatives,
such as options,  futures, indexed securities and entering into swap agreements,
can be used to  increase or decrease  the Fund's  exposure to changing  security
prices,  interest  rates or other  factors that affect the value of  securities.
However,  these  techniques  could result in losses to the Fund,  if the Manager
judges  market  conditions  incorrectly  or  employs  a  strategy  that does not
correlate  well with the Fund's other  investments.  These  techniques can cause
losses if the counterparty does not perform its promises.  An additional risk of
investing in municipal securities that are 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.

      |X|  "When-Issued"  and  "Delayed-Delivery"  Transactions.  The  Fund  can
purchase  securities  on a  "when-issued"  basis,  and may purchase or sell such
securities   on  a   "delayed-delivery"   (or   "forward   commitment")   basis.
"When-issued"  or  "delayed-delivery"  refers  to  securities  whose  terms  and
indenture  are  available  and for  which a market  exists,  but  which  are not
available for immediate delivery.

            When such  transactions are negotiated the price (which is generally
expressed in yield terms) is fixed at the time the commitment is made.  Delivery
and  payment  for the  securities  take  place  at a later  date.  Normally  the
settlement  date is within six months of the  purchase  of  municipal  bonds and
notes.  However,  the Fund may, from time to time, purchase municipal securities
having a settlement  date more than six months and possibly as long as two years
or more after the trade date. The securities are subject to change in value from
market  fluctuation  during the settlement  period. The value at delivery may be
less than the  purchase  price.  For  example,  changes in  interest  rates in a
direction other than that expected by the Manager before  settlement will affect
the value of such securities and may cause loss to the Fund. No income begins to
accrue  to the  Fund on a  when-issued  security  until  the Fund  receives  the
security at settlement of the trade.

      The Fund will engage in when-issued  transactions  in order to secure what
is considered to be an advantageous price and yield at the time of entering into
the  obligation.  When the  Fund  engages  in  when-issued  or  delayed-delivery
transactions,  it relies on the buyer or seller, as the case may be, to complete
the transaction. Its failure to do so may cause the Fund to lose the opportunity
to obtain the security at a price and yield it considers advantageous.

      When the Fund engages in when-issued and delayed-delivery transactions, it
does so for the purpose of acquiring or selling  securities  consistent with its
investment  objective and policies or for delivery pursuant to options contracts
it has entered into, and not for the purposes of investment  leverage.  Although
the Fund will enter into when-issued or delayed-delivery  purchase  transactions
to acquire securities, the Fund may dispose of a commitment prior to settlement.
If the Fund  chooses to dispose of the right to acquire a  when-issued  security
prior to its  acquisition  or to  dispose  of its right to  deliver  or  receive
against a forward commitment, it may incur a gain or loss.

      At the time the Fund makes a commitment  to purchase or sell a security on
a when-issued or forward  commitment  basis,  it records the  transaction on its
books and reflects the value of the security  purchased.  In a sale transaction,
it records the proceeds to be received,  in determining its net asset value. The
Fund will  identify  on its books  liquid  assets at least equal to the value of
purchase commitments until the Fund pays for the investment.

      When-issued  transactions and forward  commitments can be used by the Fund
as a defensive  technique to hedge against anticipated changes in interest rates
and  prices.  For  instance,  in periods of rising  interest  rates and  falling
prices,  the Fund might sell securities in its portfolio on a forward commitment
basis to attempt to limit its exposure to anticipated falling prices. In periods
of falling  interest  rates and  rising  prices,  the Fund might sell  portfolio
securities  and  purchase the same or similar  securities  on a  when-issued  or
forward commitment basis, to obtain the benefit of currently higher cash yields.

      |X| Puts and Standby Commitments.  When the Fund buys a municipal security
subject to a standby commitment to repurchase the security, the Fund is entitled
to same-day  settlement from the purchaser.  The Fund receives an exercise price
equal to the amortized cost of the underlying security plus any accrued interest
at the  time of  exercise.  A put  purchased  in  conjunction  with a  municipal
security  enables the Fund to sell the  underlying  security  within a specified
period of time at a fixed exercise price.

      The Fund might purchase a standby  commitment or put separately in cash or
it might  acquire the security  subject to the standby  commitment  or put (at a
price that reflects that additional feature).

      The Fund will enter into these transactions only with banks and securities
dealers that, in the Manager's opinion, present minimal credit risks. The Fund's
ability to  exercise a put or standby  commitment  will depend on the ability of
the bank or dealer to pay for the securities if the put or standby commitment is
exercised.  If the bank or dealer  should  default on its  obligation,  the Fund
might not be able to recover all or a portion of any loss  sustained from having
to sell the security elsewhere.

      Puts and  standby  commitments  are not  transferable  by the  Fund.  They
terminate if the Fund sells the underlying  security to a third party.  The Fund
intends to enter into these  arrangements  to  facilitate  portfolio  liquidity,
although  such  arrangements  might  enable  the  Fund to sell a  security  at a
pre-arranged  price that may be higher than the  prevailing  market price at the
time the put or standby commitment is exercised. However, the Fund might refrain
from  exercising  a  put  or  standby   commitment  if  the  exercise  price  is
significantly  higher than the prevailing market price, to avoid imposing a loss
on the seller that could jeopardize the Fund's business  relationships  with the
seller.

      A put or standby commitment increases the cost of the security and reduces
the yield otherwise  available from the security.  Any consideration paid by the
Fund for the put or standby  commitment will be reflected on the Fund's books as
unrealized  depreciation  while the put or  standby  commitment  is held,  and a
realized  gain or loss  when the put or  commitment  is  exercised  or  expires.
Interest income received by the Fund from municipal  securities  subject to puts
or stand-by  commitments may not qualify as tax exempt in its hands if the terms
of the put or  stand-by  commitment  cause the Fund not to be treated as the tax
owner of the underlying municipal securities.

      |X|  Repurchase  Agreements.  The Fund may acquire  securities  subject to
repurchase  agreements.  It may do so for liquidity purposes to meet anticipated
redemptions of Fund shares, or pending the investment of the proceeds from sales
of Fund shares, or pending the settlement of portfolio securities transactions.

      In a  repurchase  transaction,  the Fund  acquires  a security  from,  and
simultaneously  resells it to an approved  vendor for delivery on an agreed upon
future  date.  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.  Approved  vendors  include U.S.  commercial
banks,  U.S.  branches  of  foreign  banks  or  broker-dealers  that  have  been
designated  a primary  dealer in  government  securities,  which meet the credit
requirements set by the Fund's Board of Trustees from time to time.

      The majority of these  transactions run from day to day. Delivery pursuant
to  resale  typically  will  occur  within  one to five  days  of the  purchase.
Repurchase  agreements  having a maturity  beyond  seven days are subject to the
Fund's  limits on  holding  illiquid  investments.  The Fund will not enter into
transactions  that will  cause more than 25% of the  Fund's  total  assets to be
subject to repurchase agreements.

      Repurchase  agreements,  considered  "loans" under the Investment  Company
Act,  are  collateralized  by the  underlying  security.  The Fund's  repurchase
agreements  require  that at all times  while  the  repurchase  agreement  is in
effect,  the  collateral's  value 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.  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.

      |X| Illiquid  and  Restricted  Securities.  To enable the Fund to sell its
holdings of a restricted  security not  registered  under the  Securities Act of
1933,  the Fund might  have to cause  those  securities  to be  registered.  The
expenses of registering restricted securities may be negotiated by the Fund with
the issuer at the time the Fund buys the securities.  When the Fund must arrange
registration because the Fund wishes to sell the security, a considerable period
may elapse  between the time the  decision is made to sell the  security and the
time the security is  registered  so that the Fund could sell it. The Fund would
bear the risks of any downward price fluctuation during that period.

      The Fund has percentage  limitations that apply to purchases of restricted
and  illiquid  securities,  as  stated  in  the  Prospectus.   Those  percentage
restrictions do not limit  purchases of restricted  securities that are eligible
for resale to qualified institutional purchasers pursuant to Rule 144A under the
Securities Act of 1933,  provided that those  securities have been determined to
be  liquid  by the  Board  of  Directors  of the Fund or by the  Manager.  Those
guidelines  take into account the trading  activity for such  securities and the
availability of reliable pricing information, among other factors. If there is a
lack of trading interest in a particular Rule 144A security,  the Fund's holding
of that security may be deemed to be illiquid.

      The  Fund  can  also  acquire   restricted   securities   through  private
placements.  Those  securities  have  contractual  restrictions  on their public
resale.  Those  restrictions  might  limit the Fund's  ability to dispose of the
securities and might lower the amount the Fund could realize upon the sale.

      |X| Loans of  Portfolio  Securities.  To attempt to raise  income or raise
cash for  liquidity  purposes,  the Fund may lend its  portfolio  securities  to
brokers, dealers and other financial institutions. There are risks in connection
with  securities  lending.  The  Fund  might  experience  a delay  in  receiving
additional  collateral  to secure a loan,  or a delay in  recovery of the loaned
securities.  The Fund  presently does not intend to lend  securities;  but if it
does,  these loans  cannot  exceed 5% of the value of the Fund's  total  assets.
Income from securities loans does not constitute  exempt-interest income for the
purpose of paying tax-exempt dividends.

      The Fund must receive  collateral  for a loan.  Under  current  applicable
regulatory  requirements (which are subject to change), on each business day the
loan collateral must be at least equal to the value of the loaned securities. It
must consist of cash, bank letters of credit,  securities of the U.S. government
or its agencies or  instrumentalities,  or other cash  equivalents  in which the
Fund is permitted to invest.  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. The terms of the letter of credit and the issuing bank both
must be satisfactory to the Fund.

      When it lends securities, the Fund receives amounts equal to the dividends
or  interest  on the  loaned  securities.  It 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 the loan  collateral.
Either  type of  interest  may be  shared  with the  borrower.  The Fund may pay
reasonable  finder's,  administrative  or other  fees in  connection  with these
loans.  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.

      |X|  Hedging.  The Fund can use  hedging to  attempt  to  protect  against
declines  in the  market  value of its  portfolio,  to permit the Fund to retain
unrealized gains in the value of portfolio securities that have appreciated,  or
to facilitate  selling  securities  for  investment  reasons.  To do so the Fund
could:
     |_| sell interest rate futures or municipal  bond index  futures,  
     |_| buy puts on such futures or securities, or
     |_| write covered calls on  securities,  interest rate futures or municipal
bond index futures.  The Fund can also write covered calls on debt securities to
attempt to increase the Fund's income,  but that income would not be tax-exempt.
Therefore  it is  unlikely  that the Fund  would  write  covered  calls for that
purpose.

      The  Fund can  also  use  hedging  to  establish  a  position  in the debt
securities  market as a temporary  substitute  for  purchasing  individual  debt
securities.  In  that  case  the  Fund  would  normally  seek  to  purchase  the
securities,  and then terminate that hedging position. For this type of hedging,
the Fund could:
      |_| buy interest rate futures or municipal bond index futures,  or 
     |_| buy calls on such futures or on securities.

      The Fund is not  obligated to use hedging  instruments,  even though it is
permitted  to use them in the  Manager's  discretion,  as described  below.  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.
The particular  hedging  instruments the Fund can use are described  below.  The
Fund may employ new hedging  instruments and strategies when they are developed,
if those investment methods are consistent with the Fund's investment objective,
are  approved  by its Board,  and are  permissible  under the Fund's  investment
restrictions and applicable regulations.

        |_|  Futures.  The Fund can buy and sell futures  contracts  relating to
debt  securities  (these are called  "interest rate futures") and municipal bond
indices (these are referred to as "municipal bond index futures"), but only as a
hedge against interest rate changes.

      An interest rate future obligates the seller to deliver (and the purchaser
to  take)  cash or a  specific  type of debt  security  to  settle  the  futures
transaction.  Either party could also enter into an offsetting contract to close
out the futures position.

      A "municipal bond index" assigns relative values to the municipal bonds in
the index, and is used 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 only in cash. The obligation  under the contract
may also be satisfied by entering into an offsetting  contract.  The  strategies
which the Fund  employs in using  municipal  bond index  futures  are similar to
those with regard to interest rate futures.

      No money is paid by or received  by the fund on the  purchase or sale of a
futures  contract.  Upon entering into a futures  transaction,  the Fund will be
required  to  deposit  an  initial  margin  payment  in cash or U.S.  government
securities 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 daily.

      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 by their terms
call for  settlement  by the  delivery  of debt  securities,  in most  cases the
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.

      The Fund may  concurrently  buy and sell  futures  contracts in a strategy
anticipating  that the future the Fund  purchased  will perform  better than the
future the Fund sold. For example, the Fund might buy municipal bond futures and
concurrently  sell U.S.  Treasury bond futures (a type of interest rate future).
The Fund would benefit if municipal bonds  outperform  U.S.  Treasury bonds on a
duration-adjusted basis. There are risks that this type of futures strategy will
not  be   successful.   U.S.   Treasury   bonds  might   perform   better  on  a
duration-adjusted basis than municipal bonds, and the assumptions about duration
that were used might be incorrect (for example,  the duration of municipal bonds
relative to U.S. Treasury bonds might turn out to be greater than anticipated).

        |_| Put and Call Options. The Fund can buy and sell certain kinds of put
options (puts) and call options  (calls),  including  index options,  securities
options and options on futures. These strategies are described below.

     |_| Writing  Covered Call Options.  The Fund can write (that is, sell) call
options.  Calls the Fund  sells may be listed  on a  securities  or  commodities
exchange or quoted on NASDAQ, the automated quotation system of The Nasdaq Stock
Market, Inc. or traded in the over-the-counter market. Each call the Fund writes
must be  "covered"  while it is  outstanding.  That  means the Fund must own the
investment  on which the call was  written.  The Fund may write calls on futures
contracts,  but  if  it  does  not  own  the  futures  contract  or  deliverable
securities,  these calls must be covered by  securities  or other liquid  assets
that the Fund owns and segregates to enable it to satisfy its obligations if the
call is exercised. Up to 20% of the Fund's total assets may be subject to calls.

      When  the  Fund  writes  a  call  on  a  security,  it  receives  cash  (a
premium).The  Fund agrees to sell the underlying  investment to a purchaser of a
corresponding  call on the  same  security  during  the call  period  at a fixed
exercise price  regardless of market price changes  during the call period.  The
call period is usually not more than nine months.  The exercise price may differ
from the market price of the underlying security. The Fund has retained the risk
of loss that the price of the  underlying  security may decline  during the call
period. That risk may be offset to some extent by the premium the Fund receives.
If the value of the investment  does not rise above the call price, it is likely
that the call will lapse  without being  exercised.  In that case the Fund would
keep the cash premium and the investment.

      When the Fund writes a call on an index, it receives cash (a premium).  If
the buyer of the call exercises it, the Fund will pay an amount of cash equal to
the  difference  between the closing  price of the call and the exercise  price,
multiplied by the specified multiple that determines the total value of the call
for each point of difference. If the value of the underlying investment does not
rise above the call price,  it is likely that the call will lapse  without being
exercised. In that case the Fund would keep the cash premium.

      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 calls traded on exchanges,  or as to other acceptable escrow securities.
In that way, no margin will be required for such transactions.  OCC will release
the securities on the expiration of the calls or upon the Fund's entering into a
closing purchase transaction.

      When the Fund writes an  over-the-counter  ("OTC")  option,  it will enter
into an arrangement with a primary U.S. Government  securities dealer which will
establish  a formula  price at which the Fund  will have the  absolute  right to
repurchase  that OTC option.  The formula  price would  generally  be based on a
multiple of the premium  received  for the option,  plus the amount by which the
option is exercisable  below the market price of the  underlying  security (that
is, the option is  "in-the-money").  When the Fund writes an OTC option, it will
treat as illiquid (for purposes of its  restriction on illiquid  securities) the
mark-to-market  value of any OTC option held by it, unless the option is subject
to a buy-back  agreement by the executing  broker.  The  Securities and Exchange
Commission  is  evaluating  whether  OTC  options  should be  considered  liquid
securities.  The procedure  described  above could be affected by the outcome of
that evaluation.

      To  terminate  its  obligation  on a call it has  written,  the  Fund  may
purchase a corresponding call in a "closing purchase transaction." The Fund will
then realize a profit or loss,  depending  upon whether the net of the amount of
the option transaction costs and the premium received on the call the Fund wrote
was more or less than the price of the call the Fund  purchased to close out the
transaction.  A profit  may also be  realized  if the call  lapses  unexercised,
because the Fund retains the underlying investment and the premium received. Any
such profits are considered  short-term  capital gains for Federal tax purposes,
as are premiums on lapsed calls.  When  distributed by the Fund they are taxable
as ordinary income.

      The Fund may also write  calls on  futures  contracts  without  owning the
futures contract or securities  deliverable under the contract. To do so, at the
time the call is written,  the Fund must cover the call by segregating in escrow
an equivalent dollar value of 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.  Because  of  this  escrow  requirement,  in no
circumstances  would the Fund's receipt of an exercise  notice as to that future
put the Fund in a "short" futures position.

        |_| Writing Put Options.  The Fund can sell put options. A put option on
securities  gives the purchaser the right to sell, and the writer the obligation
to buy,  the  underlying  investment  at the  exercise  price  during the option
period.  The Fund  will not write  puts if,  as a  result,  more than 20% of the
Fund's  total  assets  would be  required  to be  segregated  to cover  such put
options.

      If the Fund  writes a put,  the put must be covered by  segregated  liquid
assets. The premium the Fund receives from writing a put represents a profit, as
long as the price of the  underlying  investment  remains  equal to or above the
exercise price of the put. However,  the Fund also assumes the obligation during
the option period to buy the underlying  investment from the buyer of the put at
the exercise price, even if the value of the investment falls below the exercise
price.  If a put the Fund has written expires  unexercised,  the Fund realizes a
gain in the amount of the premium less the transaction  costs  incurred.  If the
put is  exercised,  the  Fund  must  fulfill  its  obligation  to  purchase  the
underlying  investment at the exercise price. That price will usually exceed the
market value of the  investment at that time. In that case, the Fund may incur a
loss if it sells the underlying  investment.  That loss will be equal to the sum
of the sale price of the underlying  investment  and the premium  received minus
the sum of the exercise price and any transaction costs the Fund incurred.

      When writing a put option on a security,  to secure its  obligation to pay
for the underlying security the Fund will deposit in escrow liquid assets with a
value equal to or greater than the exercise price of the underlying  securities.
The Fund therefore forgoes the opportunity of investing the segregated assets or
writing calls against those assets.

      As long as the Fund's  obligation as the put writer  continues,  it may be
assigned an exercise notice by the broker-dealer through which the put was sold.
That notice will require the Fund to take  delivery of the  underlying  security
and pay the exercise price. The Fund has no control over when it may be required
to purchase the underlying security, since it may be assigned an exercise notice
at any time prior to the termination of its obligation as the writer of the put.
That obligation terminates upon expiration of the put. It may also terminate if,
before it receives  an  exercise  notice,  the Fund  effects a closing  purchase
transaction by purchasing a put of the same series as it sold. Once the Fund has
been  assigned  an  exercise  notice,   it  cannot  effect  a  closing  purchase
transaction.

      The Fund may decide to effect a closing purchase  transaction to realize a
profit on an outstanding  put option it has written or to prevent the underlying
security  from being put.  Effecting a closing  purchase  transaction  will also
permit  the Fund to write  another  put option on the  security,  or to sell the
security and use the proceeds from the sale for other investments. The Fund will
realize  a profit  or loss  from a closing  purchase  transaction  depending  on
whether the cost of the  transaction  is less or more than the premium  received
from  writing  the put option.  Any profits  from  writing  puts are  considered
short-term  capital gains for Federal tax purposes,  and when distributed by the
Fund, are taxable as ordinary income.

        |_|  Purchasing  Calls and Puts.  The Fund can buy calls on  securities,
broadly-based municipal bond indices,  municipal bond index futures and interest
rate  futures.  It can also buy  calls to close  out a call it has  written,  as
discussed  above.  Calls  the  Fund  buys  may  be  listed  on a  securities  or
commodities  exchange,  or quoted on NASDAQ,  or traded in the  over-the-counter
market.  A call or put option may not be purchased  if the purchase  would cause
the  value of all the  Fund's  put and call  options  to  exceed 5% of its total
assets.

      When  the  Fund  purchases  a  call  (other  than  in a  closing  purchase
transaction),  it pays a premium. For calls on securities that the Fund buys, it
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.
The Fund  benefits  only if (1) the call is sold at a profit  or (2) the call is
exercised when the market price of the underlying investment is above the sum of
the exercise price plus the transaction  costs and premium paid for the call. If
the call is not either  exercised or sold (whether or not at a profit),  it will
become  worthless at its  expiration  date.  In that case the Fund will lose its
premium payment and the right to purchase the underlying investment.

      The Fund can buy puts on debt  securities,  municipal  bond  indices,  and
interest  rate or  municipal  bond  index  futures,  whether  or not it owns the
underlying  investment.  When the Fund  purchases a put, it pays a premium  and,
except as to puts on indices, has the right to sell the underlying investment to
a seller of a put on a corresponding investment during the put period at a fixed
exercise price. Puts on municipal bond indices are settled in cash.

      Buying a put on an  investment  the Fund does not own (such as an index or
future)  permits  the Fund  either  to resell  the put or to buy the  underlying
investment  and sell it at the  exercise  price.  The  resale  price  will  vary
inversely to the price of the underlying investment.  If the market price of the
underlying  investment is above the exercise price and, as a result,  the put is
not exercised, the put will become worthless on its expiration date.

      Buying a put on a debt  security,  interest rate future or municipal  bond
index  future the Fund owns  enables the Fund to protect  itself  during the put
period  against a decline in the value of the  underlying  investment  below the
exercise  price by selling the  investment at the exercise  price to a seller of
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 date. In that case the
Fund  will,  have paid the  premium  but lost the  right to sell the  underlying
investment.  However,  the Fund may sell the put prior to its  expiration.  That
sale may or may not be at a profit

        |_| Risks of  Hedging  with  Options  and  Futures.  The use of  hedging
instruments requires special skills and knowledge of investment  techniques that
are  different  than what is required for normal  portfolio  management.  If the
Manager uses a hedging  instrument at the wrong time or judges market conditions
incorrectly, hedging strategies may reduce the Fund's returns.

      The Fund's option activities could 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 could pay a brokerage commission each time it buys a call or put,
sells a call, or buys or sells an underlying  investment in connection  with the
exercise of a call or put. Such commissions  might be higher on a relative basis
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.  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 investment.

      If a covered call written by the Fund is exercised on an  investment  that
has increased in value,  the Fund will be required to sell the investment at the
call  price.  It will not be able to realize  any profit if the  investment  has
increased in value above the call price.

      There is a risk in using short  hedging by selling  interest  rate futures
and municipal bond index futures or purchasing puts on municipal bond indices or
futures  to  attempt  to  protect  against  declines  in the value of the Fund's
securities.  The risk is that the prices of such futures or the applicable index
will  correlate  imperfectly  with the  behavior  of the cash (that is,  market)
prices of the Fund's securities. It is possible for example, that while the Fund
has used hedging  instruments in a short hedge, the market might advance and the
value of debt  securities held in the Fund's  portfolio  might decline.  If that
occurred,  the  Fund  would  lose  money  on the  hedging  instruments  and also
experience a decline in value of its debt securities.  However, while this could
occur over a 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.

      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 debt
securities  being hedged and movements in the price of the hedging  instruments,
the Fund might use  hedging  instruments  in a greater  dollar  amount  than the
dollar amount of debt securities being hedged.  It might do so if the historical
volatility of the prices of the debt securities being hedged is greater than the
historical volatility of the applicable index.

      The ordinary  spreads  between prices in the cash and futures  markets are
subject to distortions  due to differences in the natures of those markets.  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. 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 Fund can use  hedging  instruments  to  establish  a  position  in the
municipal  securities  markets as a  temporary  substitute  for the  purchase of
individual  securities  (long  hedging).  It is possible  that the market  might
decline.  If the Fund then concludes not to invest in such securities because of
concerns that there might be 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 purchase price of the securities.

      An  option  position  may be  closed  out only on a market  that  provides
secondary  trading for options of the same series.  There is no assurance that a
liquid  secondary market will exist for a particular  option.  If the Fund could
not effect a closing  purchase  transaction due to a lack of a market,  it would
have to hold the callable investment until the call lapsed or was exercised, and
could incur losses.

        |_| Interest Rate Swap Transactions.  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 can enter 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. Income from interest rate swaps may be taxable.

      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 can 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 under one or more swap transactions, the net amount payable on that date
shall be paid. In addition, the master netting agreement may provide that if one
party  defaults  generally or on one swap,  the  counterparty  can terminate the
swaps with that party.  Under master netting  agreements,  if there is a default
resulting  in a loss to one  party,  that  party's  damages  are  calculated  by
reference to the average cost of a  replacement  swap with respect to 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."

        |_| Regulatory  Aspects of Hedging  Instruments.  When using futures and
options on futures,  the Fund is required to operate within  certain  guidelines
and restrictions  established by the Commodity  Futures Trading  Commission (the
"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.  That 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 options 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  options on futures  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 the option exchanges.  The exchanges limit the maximum number of options that
may be  written or held by a single  investor  or group of  investors  acting in
concert.  Those limits apply  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  that 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.

      Under the Investment Company Act, when the Fund purchases an interest rate
future  or  municipal  bond  index  future,  it must  maintain  cash or  readily
marketable short-term debt instruments in an amount equal to the market value of
the investments underlying the future, less the margin deposit applicable to it.

      |X|   Temporary  Defensive  Investments.  The  securities  the  Fund can
invest in for temporary defensive purposes include the following:
     |_|  short-term  municipal  securities;   
     |_| obligations issued or guaranteed by the U.S. government or its agencies
or instrumentalities;
     |_| corporate  debt  securities  rated within the three highest grades by a
nationally recognized rating agency;
     |_|  commercial  paper  rated  "A-1" by  Standard  &  Poor's,  or  having a
comparable rating by another nationally recognized-rating agency; and
     |_|  certificates of deposit of domestic banks with assets of $1 billion or
more.

      |X| Taxable Investments.  While the Fund can invest up to 20% of its total
assets in investments  that generate income subject to income taxes, it does not
anticipate  investing  substantial  amounts of its assets in taxable investments
under normal market  conditions or as part of its normal trading  strategies and
policies. To the extent it invests in taxable securities,  the Fund would not be
able to meet its objective of providing  tax exempt income to its  shareholders.
Taxable  investments  include,  for  example,  hedging  instruments,  repurchase
agreements,  and some of the  types of  securities  it would  buy for  temporary
defensive purposes.

Investment Restrictions

      |X|  What Are  "Fundamental  Policies?"  Fundamental  policies  are  those
policies that the Fund has adopted to govern its investments that can be changed
only by the vote of a "majority" of the Fund's  outstanding  voting  securities.
Under the Investment  Company Act, such a "majority" vote is defined as the vote
of the holders of the lesser of:
      |_| 67% or  more of the  shares  present  or  represented  by  proxy  at a
      shareholder  meeting,  if the holders of more than 50% of the  outstanding
      shares are present or  represented  by proxy,  or 
     |_| more than 50% of the outstanding shares.

      The Fund's investment  objective is a fundamental  policy.  Other policies
described in the  Prospectus  or this  Statement of Additional  Information  are
"fundamental"  only if they are identified as such. The Fund's Board of Trustees
can change  non-fundamental  policies  without  shareholder  approval.  However,
significant  changes to investment  policies will be described in supplements or
updates to the  Prospectus  or this  Statement  of  Additional  Information,  as
appropriate.  The Fund's most significant  investment  policies are described in
the Prospectus.

      |X|   Does the Fund Have Additional  Fundamental Policies? The following
investment restrictions are fundamental policies of the Fund:

      |_| The Fund cannot 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 except to secure a borrowing,
and in  that  case  no more  10% of the  Fund's  total  assets  may be  pledged,
mortgaged or hypothecated. 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 can
enter into  when-issued and  delayed-delivery  transactions as described in this
Statement of Additional Information.

      |_| The Fund  cannot make loans.  However,  the Fund can  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.

      |_|  With  respect  to  75% of its  total  assets,  the  Fund  cannot  buy
securities issued or guaranteed by any one issuer (except the U.S. government or
any of its agencies or  instrumentalities),  if 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.

      |_| The Fund cannot  invest more than 25% of its total  assets in a single
industry.  As an operating  policy,  the Fund applies this restriction to 25% or
more of its total  assets.  However,  the Fund can  invest  more than 25% of its
assets in a particular  segment of the  municipal  bond market,  but it will not
invest more than 25% of its total assets in industrial revenue bonds in a single
industry.

      |_| The Fund cannot invest in real estate. However, the Fund can invest in
municipal  securities or other permissible  securities or instruments secured by
real estate or interests in real estate.

      |_| The Fund cannot  invest in  interests  in oil,  gas, or other  mineral
exploration or development programs.

      |_| The Fund cannot purchase securities, or other instruments,  on margin.
However, the Fund can invest in options, futures, options on futures and similar
instruments  and may make margin  deposits and payments in connection with those
investments.

      |_|   The Fund cannot make short sales of securities.

      |_| The Fund cannot  underwrite  securities.  A permitted  exception is in
case it is deemed to be an  underwriter  under the  Securities  Act of 1933 when
reselling in securities held in its portfolio.

      |_| The Fund cannot invest in securities  of other  investment  companies,
 except  is they  are  acquired  as part of a  merger,  consolidation  or  other
 acquisition.

      |_| The Fund cannot make investments for the purpose of exercising control
of management.

      |_| The  Fund  cannot  purchase  securities  of any  issuer  if  officers,
trustees and directors of the Fund or the Manager individually  beneficially own
more than 0.5% of the  securities  of that issuer and together own  beneficially
more than 5% of the outstanding securities.

      |_| The Fund cannot issue "senior  securities," but this does not prohibit
certain  investment  activities  for which assets of the Fund are  designated as
segregated or margin collateral or escrow  arrangements are established to cover
the related  obligations.  Examples of those activities include borrowing money,
reverse repurchase agreements, delayed-delivery and when-issued arrangements for
portfolio  securities  transactions,  and contracts to buy or sell  derivatives,
hedging instruments, options or futures.

      The Fund will 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,  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,  unless the
security is rated by a nationally-recognized  rating service. In each case, that
period may  include the  operation  of  predecessor  companies  or  enterprises.
Additionally,  the Fund will not invest in common stock or any warrants  related
to common stocks. These operating policies are not fundamental policies.

      Unless the Prospectus or Statement of Additional Information states that a
percentage  restriction applies on an ongoing basis, it applies only at the time
the Fund makes an investment.  In that case 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.

Diversification.  The  Fund  intends  to be  "diversified"  as  defined  in  the
Investment  Company Act and to satisfy the  restrictions  against  investing too
much of its assets in any "issuer" as set forth in the  restrictions  above.  In
implementing  this  policy,  the  identification  of the  issuer of a  municipal
security  depends on the terms and  conditions of the security.  When the assets
and  revenues  of an  agency,  authority,  instrumentality  or  other  political
subdivision  are  separate  from  those of the  government  creating  it and the
security is backed only by the assets and revenues of the  subdivision,  agency,
authority or instrumentality,  the latter would be deemed to be the sole issuer.
Similarly,  if an industrial  development  bond is backed only by the assets and
revenues of the non-governmental  user, then that user would be deemed to be the
sole issuer.  However,  if in either case the creating  government or some other
entity  guarantees  a security,  the  guarantee  would be  considered a separate
security and would be treated as an issue of such government or other entity.

Applying the Restriction Against  Concentration.  To implement its policy not to
concentrate its investments,  the Fund has adopted the industry  classifications
set forth in  Appendix B to this  Statement  of  Additional  Information.  Those
industry classifications are not a fundamental policy.

      In implementing the Fund's policy not to concentrate its investments,  the
Manager  will  consider  a  non-governmental  user  of  facilities  financed  by
industrial  development  bonds as being in a particular  industry.  That is done
even  though  the bonds are  municipal  securities,  as to which the Fund has no
concentration  limitation.   Although  this  application  of  the  concentration
restriction  is not a  fundamental  policy of the Fund,  it will not be  changed
without shareholder approval.

How the Fund Is Managed

Organization  and  History.  The  Fund  is  one of  two  diversified  investment
portfolios, or "series" of Oppenheimer Municipal Fund, an open-end,  diversified
management  investment  company  organized as a Massachusetts  business trust in
1986, with an unlimited number of authorized shares of beneficial interest.

     Oppenheimer Municipal Fund (and therefore,  the Fund, as one of its series)
is governed by a Board of Trustees,  which is  responsible  for  protecting  the
interests  of   shareholders   under   Massachusetts   law.  The  Trustees  meet
periodically  throughout the year to oversee the Fund's  activities,  review its
performance,  and review the actions of the Manager.  Although the Fund will not
normally  hold annual  meetings  of its  shareholders,  it may hold  shareholder
meetings from time to time on important  matters.  Shareholders  of  Oppenheimer
Municipal  Fund have the right to call a meeting  to remove a Trustee or to take
other action described in the Declaration of Trust.

      |X|  Classes  of Shares.  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 classes invest in the same investment
portfolio.  Shares  are  freely  transferable.   Each  share  has  one  vote  at
shareholder  meetings,  with fractional shares voting  proportionally on matters
submitted to the vote of shareholders. Each class of shares:
     |_| has its own dividends and distributions,
     |_| pays certain expenses which may be different for the different classes,
     |_| may have a different net asset value,  may have separate  voting rights
on matters in which the interests of one class are different  from the interests
of another class, and
     |_| votes as a class on matters that affect that class alone.

      |X|  Meetings of  Shareholders.  As a series of a  Massachusetts  business
trust,  the Fund is not  required  to hold,  and does not plan to hold,  regular
annual meetings of shareholders. The Fund will hold meetings when required to do
so by the  Investment  Company Act or other  applicable  law. It will also do so
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 Oppenheimer  Municipal Fund, 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  Oppenheimer  Municipal  Fund. If the Trustees  receive a
request from at least 10 shareholders stating that they wish to communicate with
other  shareholders to request a meeting to remove a Trustee,  the Trustees will
then either make the shareholder  lists of Oppenheimer  Municipal Fund available
to the applicants or mail their  communication to all other  shareholders at the
applicants'  expense.  The  shareholders  making  the  request  must  have  been
shareholders  for at least  six  months  and  must  hold  shares  of  series  of
Oppenheimer Municipal Fund valued at $25,000 or more or constituting at least 1%
of the outstanding shares of Oppenheimer  Municipal Fund, whichever is less. The
Trustees may also take other action as permitted by the Investment Company Act.

        |_| Shareholder and Trustee Liability. The Declaration of Trust contains
an  express  disclaimer  of  shareholder  or  Trustee  liability  for the Fund's
obligations.  It also provides for indemnification and reimbursement of expenses
out of the Fund's  property for any shareholder  held personally  liable for its
obligations.  The  Declaration of Trust also states that upon request,  the Fund
shall assume the defense of any claim made against a shareholder  for any act or
obligation   of  the  Fund  and  shall  satisfy  any  judgment  on  that  claim.
Massachusetts  law permits a shareholder  of a business trust (such as the Fund)
to be  held  personally  liable  as a  "partner"  under  certain  circumstances.
However,  the risk that a Fund  shareholder will incur financial loss from being
held  liable as a  "partner"  of the Fund is  limited to the  relatively  remote
circumstances in which the Fund would be unable to meet its obligations.

      The Fund's  contractual  arrangements state that any person doing business
with the Fund (and each shareholder of the Fund) agrees under the Declaration of
Trust to look solely to the assets of the Fund for  satisfaction of any claim or
demand that may arise out of any dealings with the Fund.  The contracts  further
state that the Trustees shall have no personal  liability to any such person, to
the extent permitted by law.

      |X| Remuneration of Trustees.  The officers of the Fund and three Trustees
of the Fund (Ms. Macaskill and Messrs.  Bowen and Swain) are affiliated with the
Manager and receive no salary or fee from the Fund.  The  remaining  Trustees of
the Fund received the compensation  shown below. The compensation  from the Fund
was paid during its fiscal year ended September 30, 1998. The compensation  from
all of the Denver-based  Oppenheimer  funds includes the  compensation  from the
Fund and  represents  compensation  received  as a director,  trustee,  managing
general  partner or member of a committee of the Board during the calendar  year
1998.

      |X| Deferred  Compensation  Plan for  Trustees.  The Board of Trustees has
adopted a Deferred  Compensation  Plan for  disinterested  trustees that enables
them 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 level of
compensation  to any Trustee.  Pursuant to an Order issued by the Securities and
Exchange  Commission,  the Fund may invest in the funds  selected by the Trustee
under  the  plan  without  shareholder  approval  for  the  limited  purpose  of
determining the value of the Trustee's deferred fee account.

      |X|   Major  Shareholders.  As of January 4, 1999,  the only  person who
owned of record or who was  known by the Fund to own  beneficially  5% or more
of any class of the Fund's outstanding shares was:

      Merrill Lynch Pierce  Fenner & Smith,  Inc.  (which  advised the Fund that
such shares were held beneficially for its customers) 4800 Deer Lake Drive East,
Floor 3,  Jacksonville,  Florida 32246,  which owned  63,993.123  Class B shares
(approximately  6.48% of the Class B shares  then  outstanding)  and  94,609.387
Class C shares (approximately 7.32% of the Class C shares then outstanding).

The Manager.  The Manager is  wholly-owned by Oppenheimer  Acquisition  Corp., a
holding company controlled by Massachusetts  Mutual Life Insurance Company.  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 enforced by the
Manager.

      |X| The Investment  Advisory  Agreement.  The Manager provides  investment
advisory  and  management  services  to the Fund  under an  investment  advisory
agreement  between the Manager and the Fund. The Manager selects  securities for
the Fund's portfolio and handles its day-to day business.  The portfolio manager
of the Fund is  employed  by the  Manager  and is the person who is  principally
responsible for the day-to-day  management of the Fund's  investment  portfolio.
Other members of the Manager's Fixed-Income Portfolio Team provide the portfolio
manager with research and counsel in managing the Fund's investments.

      The agreement  requires the Manager,  at its expense,  to provide the Fund
with  adequate  office space,  facilities  and  equipment.  It also requires the
Manager to provide  and  supervise  the  activities  of all  administrative  and
clerical  personnel required to provide effective  corporate  administration for
the Fund.  Those  responsibilities  include the  compilation  and maintenance of
records with respect to the Fund's  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.

      The Fund pays  expenses  not  expressly  assumed by the Manager  under the
advisory  agreement.  The advisory  agreement lists examples of expenses paid by
the Fund. The major categories relate to interest,  taxes, fees to disinterested
Trustees, legal and audit expenses, custodian and transfer agent expenses, share
issuance costs, certain printing and registration costs,  brokerage commissions,
and non-recurring expenses, including litigation costs. The management fees paid
by the  Fund  to the  Manager  are  calculated  at the  rates  described  in the
Prospectus, which are applied to the assets of the Fund as a whole. The fees are
allocated  to each class of shares  based upon the  relative  proportion  of the
Fund's net assets  represented by that class.  The  management  fees paid by the
Fund to the Manager during its last three fiscal years are listed below.

      The investment  advisory  agreement  states that in the absence of willful
misfeasance,  bad faith,  gross negligence in the performance of its duties,  or
reckless disregard for its obligations and duties under the investment  advisory
agreement,  the  Manager is not liable for any loss  sustained  by reason of any
investment of the Fund assets made with due care and in good faith.

      The  agreement  permits the Manager to act as  investment  adviser for any
other person, firm or corporation. The Manager can use the name "Oppenheimer" in
connection with other  investment  companies for which it or an affiliate is the
investment adviser or general distributor. If the Manager shall no longer act as
investment  adviser to the Fund,  the Manager can withdraw its permission to the
Fund (and to Oppenheimer  Municipal Fund) to use the name  "Oppenheimer" as part
of its name.

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 buy and sell portfolio
securities for the Fund. The investment advisory agreement allows the Manager to
use  broker-dealers  to effect  the  Fund's  portfolio  transactions.  Under the
agreement,  the Manager may employ those broker-dealers  (including "affiliated"
brokers,  as that term is defined in the  Investment  Company Act) that,  in the
Manager's best judgment based on all relevant factors, will implement the Fund's
policy to obtain,  at  reasonable  expense,  the "best  execution"  of portfolio
transactions.  "Best execution"  refers to prompt and reliable  execution at the
most  favorable  price  obtainable.   The  Manager  need  not  seek  competitive
commission bidding. However, the Manager 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 investment  advisory  agreement,  the Manager may select brokers
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  charge,  if  the  Manager  makes  a good  faith  determination  that  the
commission is fair and reasonable in relation to the services provided.  Subject
to those other  considerations,  as a factor in selecting brokers for the Fund's
portfolio  transactions,  the Manager may also  consider  sales of shares of the
Fund and other investment companies managed by the Manager or its affiliates.

Brokerage Practices Followed by the Manager. The Manager allocates brokerage for
the Fund subject to the provisions of the investment  advisory agreement and the
procedures and rules described above.  Generally the Manager's portfolio traders
allocate brokerage upon  recommendations  from the Manager's portfolio managers.
In certain instances,  portfolio managers may directly place trades and allocate
brokerage.  In either case,  the  Manager's  executive  officers  supervise  the
allocation of brokerage.

      Most securities  purchases made by the Fund are in principal  transactions
at net prices.  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 the Manager determines that a better price or execution may
be obtained  by using the  services  of a broker.  Therefore,  the Fund does not
incur  substantial   brokerage  costs.   Portfolio   securities  purchased  from
underwriters  include  a  commission  or  concession  paid by the  issuer to the
underwriter in the price of the security.  Portfolio  securities  purchased 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. In an option  transaction,  the Fund ordinarily uses the same broker
for the purchase or sale of the option and any  transaction in the investment to
which the option  relates.  Other funds  advised by the Manager have  investment
objectives  and  policies  similar to those of the Fund.  Those  other funds may
purchase or sell the same  securities  as the Fund at the same time as the Fund,
which could affect the supply and price of the  securities.  When possible,  the
Manager tries to combine concurrent orders to purchase or sell the same security
by more than one of the accounts  managed by the Manager or its affiliates.  The
transactions  under those combined orders are averaged as to price and allocated
in accordance with the purchase or sale orders actually placed for each account.

      The  investment   advisory  agreement  permits  the  Manager  to  allocate
brokerage for research services.  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.  Investment  research  received  by the  Manager  for  the
commissions  paid by those other accounts may be useful both to the Fund and one
or more of the Manager's other  accounts.  Investment  research  services may be
supplied  to the Manager by a third  party at the  instance of a broker  through
which trades are placed.  Investment  research services include  information and
analyses on particular  companies  and  industries as well as market or economic
trends and portfolio  strategy,  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  permits  the  Manager to use stated  commissions  on  secondary
fixed-income  agency trades to obtain  research if the broker  represents 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
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 research services provided by brokers broaden the scope and supplement
the research activities of the Manager.  That research provides additional views
and  comparisons  for  consideration  and helps  the  Manager  to obtain  market
information  for the valuation of securities  that are either held in the Fund's
portfolio or are being considered for purchase. The Manager provides information
to the  Board of the Fund  about  the  commissions  paid to  brokers  furnishing
research services, together with the Manager's representation that the amount of
such  commissions  was  reasonably  related  to the  value  or  benefit  of such
services.

Distribution and Service Plans

The Distributor.  Under its General  Distributor's  Agreement with the Fund, the
Distributor  acts as the Fund's principal  underwriter in the continuous  public
offering of the different  classes of shares of the Fund. The Distributor is not
obligated to sell a specific number of shares. Expenses normally attributable to
sales are borne by the Distributor.

      The compensation paid to (or retained by) the Distributor from the sale of
shares or on the redemption of shares is discussed in the table below:

Distribution  and Service  Plans.  The Fund has  adopted a Service  Plan for its
Class A shares and  Distribution  and Service  Plans for its Class B and Class C
shares under Rule 12b-1 of the Investment  Company Act.  Under those plans,  the
Fund makes  payments to the  Distributor  in  connection  with the  distribution
and/or servicing of the shares of the particular class.

      Each  plan has been  approved  by a vote of the Board of  Trustees  of the
Fund,  including a majority of the  Independent  Trustees,o  cast in person at a
meeting  called for the purpose of voting on that plan.  Each plan has also been
approved by a vote of the holders of a "majority"  (as defined in the Investment
Company  Act) of the shares of each class.  The Manager cast the vote to approve
the Class C plan as the sole initial holder of Class C shares.

o In  accordance  with  Rule  12b-1  of the  Investment  Company  Act,  the term
"Independent  Trustees" in this  Statement of Additional  Information  refers to
those Trustees who are not "interested  persons" of the Fund or its parent trust
and who do not have any direct or indirect  financial  interest in the operation
of the distribution plan or any agreement under the plan.

      Under the plans the Manager and the Distributor, in their sole discretion,
from time to time may use their own resources (at no direct cost to the Fund) to
make  payments  to  brokers,   dealers  or  other  financial   institutions  for
distribution  and  administrative  services  they  perform.  The Manager may use
profits from the advisory fee it receives from the Fund. The Distributor and the
Manager  may,  in their sole  discretion,  increase  or  decrease  the amount of
payments they make to plan recipients from their own resources.

      Unless a plan is  terminated  as described  below,  the plan  continues in
effect  from year to year,  but only if the  Fund's  Board of  Trustees  and its
Independent  Trustees  specifically  vote  annually to approve its  continuance.
Approval must be by a vote cast in person at a meeting called for the purpose of
voting on continuing  the plan. A 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.

      The  Board  and  the  Independent   Trustees  must  approve  all  material
amendments to a plan. An amendment to increase materially the amount of payments
to be made under the plan must be approved by shareholders of the class affected
by the  amendment.  Because  Class B shares  automatically  convert into Class A
shares  after six years,  the Fund must obtain the  approval of both Class A and
Class B shareholders  for an amendment to the Class A plan that would materially
increase  the  amount to be paid under that  plan.  That  approval  must be by a
"majority"  (as  defined in the  Investment  Company  Act) of the shares of each
class, voting separately by Class.

      While the plans are in effect,  the  Treasurer  of the Fund shall  provide
separate  written  reports on the plans to the Fund's Board of Trustees at least
quarterly  for its review.  The reports  shall detail the amount of all payments
made under a plan and the purpose for which the payments  were made.  The report
on  the  Class  B and  Class  C  plans  shall  also  include  the  Distributor's
distribution  costs for the quarter,  and any costs for previous  fiscal periods
that have been  carried  forward.  Those  reports  are subject to the review and
approval of the Independent Trustees in the exercise of their fiduciary duty.

      Each plan states that while it is in effect,  the selection or replacement
and nomination of those Trustees of the Fund who are not "interested persons" of
the Fund is  committed  to the  discretion  of the  Independent  Trustees.  This
provision  does not  prevent  the  involvement  of others in the  selection  and
nomination  process as long as the final  decision as to selection or nomination
is approved by a majority of the Independent Trustees.

      Under the plan for a class,  no payment  will be made to any  recipient in
any  quarter in which the  aggregate  net asset value of all Fund shares held by
the recipient for itself and its customers does not exceed a minimum amount,  if
any,  that may be set from time to time by a majority of the Fund's  Independent
Trustees.  The Board of Trustees  has set the fees at the maximum  rate  allowed
under  the plans and has set no  minimum  asset  amount  needed to  qualify  for
payments.

         |X|  Class A  Service  Plan.  Under  the  Class  A  service  plan,  the
Distributor  currently  uses the fees it receives  from the Fund to pay brokers,
dealers and other financial  institutions (they are referred to as "recipients")
for personal  services and account  maintenance  services they provide for their
customers who hold Class A shares. The services 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.  The  Distributor
makes  payments  to plan  recipients  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.

      For the fiscal year ended September 30, 1998,  payments under the Plan for
Class A shares  totaled  $235,579,  all of which was paid by the  Distributor to
recipients.  That included $30,812 paid to an affiliate of the Distributor.  Any
unreimbursed  expenses the Distributor incurs with respect to Class A shares for
any fiscal year may not be recovered in subsequent  years.  The  Distributor may
not use  payments  received  under the  Class A plan to pay any of its  interest
expenses, carrying charges, other financial costs, or allocation of overhead.

      |X| Class B and Class C Service and Distribution  Plans.  Under each plan,
service fees and distribution  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 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 under
the plans during that period.  The types of services that recipients provide are
similar to the services provided under the Class A plan, described above.

      The Class B and Class C plans  permit the  Distributor  to retain both the
asset-based sales charges and the service fee on shares or to pay recipients the
service  fee on a quarterly  basis,  without  payment in  advance.  The types of
services that recipients  provide are similar to the services provided under the
Class A plan, described above. However, the Distributor presently intends to pay
recipients  the  service  fee on Class B and Class C shares in  advance  for the
first  year the  shares  are  outstanding.  After  the  first  year  shares  are
outstanding,  the  Distributor  makes  service fee  payments  quarterly on those
shares.  The  advance  payment is based on the net asset  value of shares  sold.
Shares  purchased by exchange do not qualify for an advance service fee payment.
If Class B or Class C shares are  redeemed  during  the first  year after  their
purchase, the recipient of the service fees on those shares will be obligated to
repay the  Distributor  a pro rata portion of the advance  payment made on those
shares.

      The Distributor  retains the  asset-based  sales charge on Class B shares.
The Distributor  retains the  asset-based  sales charge on Class C shares during
the first year the shares are outstanding.  It pays the asset-based sales charge
as an ongoing  commission to the dealer on Class C shares outstanding for a year
or  more.  If a  dealer  has a  special  agreement  with  the  Distributor,  the
Distributor will pay the Class B and/or Class C service fees and the asset-based
sales charge to the dealer  quarterly in lieu of paying the sales commission and
service fee in advance at the time of purchase.

      The  asset-based  sales  charge  on  Class  B and  Class C  shares  allows
investors to buy shares  without a front-end  sales  charge  while  allowing the
Distributor  to  compensate  dealers that sell those shares.  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 plans. The Fund pays the asset-based
sales charge to the Distributor for its services rendered in distributing  Class
B and Class C shares.  The payments are made to the  Distributor  in recognition
that the Distributor:
      |_|pays sales  commissions  to authorized  brokers and dealers at the time
         of sale and pays service fees as described in the Prospectus,
      |_|may  finance  payment of sales  commissions  and/or the  advance of the
         service fee payment to recipients  under the plans, or may provide such
         financing from its own resources or from the resources of an affiliate,
      |_|   employs personnel to support distribution of shares, and
      |_|   bears 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.

      Payments  made under the Class B plan for the fiscal year ended  September
30,  1998,  totaled  $108,144  (including  $403  paid  to an  affiliate  of  the
Distributor).  The Distributor retained $94,754 of the total paid. Payments made
under the Class C Plan for the fiscal  year ended  September  30,  1998  totaled
$163,567  (including  $3,923  paid  to an  affiliate  by the  Distributor).  The
Distributor  retained  $84,598 of the total paid.  At September  30,  1998,  the
Distributor  had incurred  unreimbursed  expenses  under the Class B plan in the
amount of $273,649 (equal to 2.02% of the Fund's net assets represented by Class
B shares on that date).  At September  30, 1998,  the  Distributor  had incurred
unreimbursed  expenses under the Class C plan of $259,730 (equal to 1.47% of the
Fund's net assets

represented by Class C shares on that date). 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 the  Distributor  to compensate it for its expenses
incurred for distributing shares before the plan was terminated.

      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 to NASD members.

Performance of the Fund

Explanation  of  Performance  Terminology.  The Fund uses a variety  of terms to
illustrate  its   performance.   These  terms  include   "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."  An  explanation  of how  yields  and total
returns are  calculated  is set forth  below.  The charts  below show the Fund's
performance  as of its most  recent  fiscal  year end.  You can  obtain  current
performance  information by calling the Fund's Transfer Agent at  1-800-525-7048
or    by    visiting    the    OppenheimerFunds    Internet    web    site    at
http://www.oppenheimerfunds.com.

      The Fund's  illustrations of its performance data in  advertisements  must
comply  with  rules of the  Securities  and  Exchange  Commission.  Those  rules
describe  the  types of  performance  data  that may be used and how it is to be
calculated.  In general,  any  advertisement by the Fund of its performance data
must include the average annual total returns for the advertised class of shares
of the Fund.  Those  returns must be shown 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  (or its submission for
publication).  Certain types of yields may also be shown, provided that they are
accompanied by standardized average annual total returns.

      Use of  standardized  performance  calculations  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 the
Fund's performance information as a basis for comparison with other investments:
      |_| Yields and total returns  measure the  performance  of a  hypothetical
account in the Fund over various periods and do not show the performance of each
shareholder's  account.  Your  account's  performance  will  vary from the model
performance  data if your  dividends  are  received in cash,  or you buy or sell
shares  during the period,  or you bought  your  shares at a different  time and
price than the shares used in the model.
      |_|   The Fund's performance  returns do not reflect the effect of taxes
on distributions.
      |_|   An  investment in the Fund is not insured by the FDIC or any other
government agency.
      |_| The  principal  value of the Fund's  shares,  and its yields and total
returns are not guaranteed and normally will fluctuate on a daily basis.
      |_| When an investor's shares are redeemed, they may be worth more or less
than their original cost.
      |_|  Yields  and  total  returns  for  any  given  past  period  represent
historical performance information and are not, and should not be considered,  a
prediction of future yields or returns.

      The performance of each class of shares is shown  separately,  because the
performance  of each class of shares will usually be different.  That is because
of the  different  kinds of  expenses  each  class  bears.  The yields and total
returns of each class of shares of the Fund are  affected by market  conditions,
the quality of the Fund's  investments,  the maturity of those investments,  the
types of  investments  the  Fund  holds,  and its  operating  expenses  that are
allocated to the particular class.

      |X| Yields.  The Fund uses a variety of different yields to illustrate its
current returns. Each class of shares calculates its yield separately because of
the different expenses that affect each class.

        |_| Standardized Yield. The "standardized  yield" (sometimes referred to
just 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.

      Standardized  yield 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:

- ------------------------------------------------------------------------------
                                             a-b       6
                   Standardized Yield = 2 ((------ + 1) - 1)
                                              cd

- ------------------------------------------------------------------------------
      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 assumptions).

      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 particular 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.

        |_| Dividend Yield. The Fund may quote a "dividend yield" for each class
of its  shares.  Dividend  yield is based  on the  dividends  paid on a class of
shares 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 current 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.

        |_|  Tax-Equivalent  Yield.  The  "tax-equivalent  yield"  of a class of
shares  is the  equivalent  yield  that  would  have to be  earned  on a taxable
investment  to  achieve  the  after-tax   results   represented  by  the  Fund's
tax-equivalent  yield. It adjusts the Fund's  standardized  yield, as calculated
above, by a stated Federal tax rate. Using different tax rates to show different
tax  equivalent  yields  shows  investors  in  different  tax  brackets  the tax
equivalent yield of the Fund based on their own tax bracket.

      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. The result is added 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.  Your tax bracket is determined by your 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.

      |X| Total Return Information. There are different types of "total returns"
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
and that  the  investment  is  redeemed  at the end of the  period.  Because  of
differences  in expenses  for each class of shares,  the total  returns for each
class are separately  measured.  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 actual  year-by-year  performance.  The
Fund uses  standardized  calculations for its total returns as prescribed by the
SEC. The methodology is discussed below.

            In calculating total returns for Class A shares, the current maximum
sales charge of 3.5% (as a percentage  of the offering  price) is deducted  from
the initial  investment  ("P") (unless the return is shown without sales charge,
as described below).  For Class B shares,  payment of the applicable  contingent
deferred  sales charge is applied,  depending on the period for which the return
is shown: 4.0% in the first year, 3.0% in the second year, 2.0% in the third and
fourth years,  1.0% in the fifth year, and none thereafter.  For Class C shares,
the 1% contingent  deferred  sales charge is deducted for returns for the 1-year
period.

        |_| Average  Annual Total Return.  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" in the
formula) of that investment, according to the following formula:

- ------------------------------------------------------------------------------
                    ( ERV ) 1/n
                    (-----) -1 = Average Annual Total Return
                    (  P  )
- ------------------------------------------------------------------------------
        |_| Cumulative Total Return.  The "cumulative total return"  calculation
measures  the change in 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
                             ------- = Total Return
                                P
- ------------------------------------------------------------------------------
        |_| Total  Returns  at Net Asset  Value.  From time to time the Fund may
also quote a cumulative  or an average  annual total return "at net asset value"
(without  deducting sales charges) 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.

Other  Performance  Comparisons.  The Fund compares its performance  annually to
that of an  appropriate  broadly  based  market  index in its  Annual  Report to
shareholders.  You can obtain that  information by contacting the Transfer Agent
at the addresses or telephone  numbers  shown on the cover of this  Statement of
Additional  Information.  The Fund may also compare its  performance  to that of
other  investments,  including  other  mutual  funds,  or  use  rankings  of its
performance  by  independent  ranking  entities.  Examples of these  performance
comparisons are set forth below.

      |X| Lipper Rankings. From time to time the Fund may publish the ranking of
the performance of its shares by Lipper Analytical  Services,  Inc.  ("Lipper").
Lipper is 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 by Lipper against
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.  Lipper also publishes "peer-group" indices of the performance of
all mutual funds in a category that it monitors and averages of the  performance
of the funds in particular categories.

      |X| Morningstar Rankings.  From time to time the Fund may publish the star
ranking of the  performance  of its classes of 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.  The Fund is ranked among municipal
bond funds.

      Morningstar  star  rankings are based on  risk-adjusted  total  investment
return.  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 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%
of funds in a category), 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 date 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.

      |X|   Performance   Rankings  and   Comparisons   by  Other  Entities  and
Publications.  From time to time the Fund may include in its  advertisements and
sales literature performance  information about the Fund cited in newspapers and
other periodicals such as The New York Times, The Wall Street Journal, Barron's,
or similar  publications.  That information 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 the
performance  of various  market  indices  or other  investments,  and  averages,
performance  rankings or other  benchmarks  prepared by  recognized  mutual fund
statistical services.

      Investors  may also wish to compare the Fund's Class A, Class B or Class C
returns  to the  return on  fixed-income  investments  available  from banks and
thrift   institutions.   Those  include   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.
Repayment of principal and payment of interest on Treasury  securities is backed
by the full faith and credit of the U.S. government.

      From time to time, the Fund may publish rankings or ratings of the Manager
or Transfer Agent, and of the investor services provided by them to shareholders
of the Oppenheimer  funds,  other than  performance  rankings of the Oppenheimer
funds themselves. Those ratings or rankings of shareholder and investor services
by third parties may include  comparisons of their services to those provided by
other mutual fund families selected by the rating or ranking services.  They may
be based upon the opinions of the rating or ranking  service  itself,  using its
research or judgment, or based upon surveys of investors,  brokers, shareholders
or others.

ABOUT YOUR ACCOUNT

How to Buy Shares

Additional  information is presented below about the methods that can be used to
buy shares of the Fund.  Appendix C contains more information  about the special
sales charge  arrangements  offered by the Fund, and the  circumstances in which
sales charges may be reduced or waived for certain classes of investors.

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 ("ACH")
transfer to buy the shares.  Dividends will begin to accrue on shares  purchased
with 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. The proceeds of ACH  transfers  are normally
received by the Fund 3 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 Appendix C to this
Statement of Additional  Information because the Distributor or dealer or broker
incurs little or no selling expenses.

      |X| 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 for your  joint  accounts,  or for trust or  custodial  accounts  on
         behalf of your children who are minors, and
      |_|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, and
      |_|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.

     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.  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 reduced sales charge will apply only to current purchases. You must
request it when you buy shares.

      |X| The  Oppenheimer  Funds.  The  Oppenheimer  funds are  those  mutual
funds  for   which   the   Distributor   acts  as  the   distributor   or  the
sub-distributor and currently include the following:

      There is an initial sales charge on the purchase of Class A shares of each
of  the  Oppenheimer  funds  except  the  money  market  funds.   Under  certain
circumstances described in this Statement of Additional Information,  redemption
proceeds of certain  money  market  fund  shares may be subject to a  contingent
deferred sales charge.

Letters 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.  You can include  purchases made up
to 90 days before the date of the Letter.

      A  Letter  of  Intent  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").  At the  investor's  request,  this  may  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 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.  However,  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. That amount is described in "Terms of
Escrow,"  below  (those  terms may be  amended by the  Distributor  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 a Letter of Intent. If those terms are amended,  as they may be from time to
time by the Fund,  the  investor  agrees to be bounded by the amended  terms and
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  Prospectus,  the sales
charges paid will be adjusted to the lower rate.  That  adjustment  will be made
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.

      |X|   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  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.  That sales charge  adjustment  will
apply to any shares  redeemed  prior to the  completion  of the  Letter.  If the
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  by exchange of either (1) Class A
          shares  of one of the  other  Oppenheimer  funds  that  were  acquired
          subject to a Class A initial or  contingent  deferred  sales charge or
          (2)  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 to buy shares  directly
from a bank  account,  you must  enclose a check  (minimum  $25) for the initial
purchase with your application.  Shares purchased by Asset Builder Plan payments
from bank  accounts  are  subject  to the  redemption  restrictions  for  recent
purchases  described  in  the  Prospectus.   Asset  Builder  Plans  also  enable
shareholders  of  Oppenheimer  Cash  Reserves to use their fund  account to make
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 Application. Neither
the  Distributor,  the Transfer Agent nor the Fund shall be responsible  for any
delays in purchasing shares resulting from delays in ACH transmissions.

      Before  initiating  Asset  Builder  payments,  obtain a prospectus  of the
selected  fund(s) from the Distributor or your financial  advisor and request an
application from the  Distributor,  complete it and return it. 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.  The  Transfer  Agent
requires a  reasonable  period  (approximately  15 days)  after  receipt of such
instructions to implement  them. The Fund reserves the right to amend,  suspend,
or discontinue offering Asset Builder 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.

Classes of Shares.  Each class of shares of the Fund  represents  an interest in
the same portfolio of investments of the Fund. However, each class has different
shareholder  privileges and features.  The net income attributable to Class B or
Class C shares and the  dividends  payable on Class B or Class C shares  will be
reduced by  incremental  expenses  borne  solely by that class.  Those  expenses
include the asset-based sales charges to which Class B and Class C are subject.

      The  availability of three classes of shares permits an investor to choose
the method of purchasing shares that is more appropriate for the investor.  That
may  depend  on the  amount of the  purchase,  the  length of time the  investor
expects  to hold  shares,  and  other  relevant  circumstances.  Class A  shares
normally are sold subject to an initial sales charge.  While Class B and Class C
shares have no initial  sales charge,  the purpose of the deferred  sales charge
and  asset-based  sales charge on Class B and Class C shares is the same as that
of the initial sales charge on Class A shares-to  compensate the Distributor and
brokers,  dealers and  financial  institutions  that sell shares of the Fund.  A
salesperson  who is  entitled to receive  compensation  from his or her firm for
selling Fund shares may receive different levels of compensation for selling one
class of shares than another.

      The  Distributor  will not accept any order in the amount of  $500,000  or
more for Class B shares or $1  million or more for Class C shares on behalf of a
single investor (not including dealer "street name" or omnibus  accounts).  That
is because  generally it will be more advantageous for that investor to purchase
Class A shares of the Fund.

      |X| Class B Conversion. 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.

      |X|  Allocation of Expenses.  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 shares,  and  therefore  are  indirectly  borne by  shareholders
through their investment.

      The  methodology  for  calculating  the net  asset  value,  dividends  and
distributions  of the Fund's  share  classes  recognizes  two types of expenses.
General expenses that do not pertain specifically to any one class are allocated
pro rata to the shares of all classes. The allocation is based on the percentage
of the Fund's total assets that is represented by the assets of each class,  and
then  equally to each  outstanding  share  within a given  class.  Such  general
expenses include  management fees, legal,  bookkeeping and audit fees,  printing
and mailing costs of shareholder reports, Prospectuses, Statements of Additional
Information and other materials for current  shareholders,  fees to unaffiliated
Trustees,  custodian expenses,  share issuance costs,  organization and start-up
costs, interest,  taxes and brokerage commissions,  and non-recurring  expenses,
such as litigation costs.

      Other expenses that are directly  attributable  to a particular  class are
allocated equally to each outstanding share within that class.  Examples of such
expenses  include  distribution  and service  plan  (12b-1)  fees,  transfer and
shareholder servicing agent fees and expenses,  and shareholder meeting expenses
(to the extent that such expenses pertain only to a specific class).

Determination  of Net Asset Values Per Share.  The net asset values per share of
each class of shares of the Fund are  determined  as of the close of business of
The New York Stock Exchange on each day that the Exchange is open. It is done 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 other 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 days on which the  Exchange  is closed  (including  weekends  and
holidays)  or after 4:00 P.M. on a regular  business  day.  The Fund's net asset
values will not be  calculated  on those days,  and the values of some of Fund's
portfolio  securities may change  significantly on those days, when shareholders
cannot purchase or redeem shares.

      |X|   Securities   Valuation.   The  Fund's   Board  of   Trustees   has
established procedures for the valuation of the Fund's securities.  In general
those procedures are as follows:

      |_| 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 Fund's  Board of
Trustees  or  obtained  by the  Manager  from two  active  market  makers in the
security on the basis of reasonable inquiry.

         |_| The following  securities  are valued at the mean between the "bid"
and "asked" prices  determined by a pricing service approved by the Fund's Board
of Trustees or obtained  by the  Manager  from two active  market  makers in the
security on the basis of reasonable inquiry:

(1)   debt   instruments   that  have  a  maturity   of  more  than  397  days
         when-issued,

(2)      debt  instruments  that had a maturity of 397 days or less  when-issued
         and have a remaining maturity of more than 60 days, and

(3)      non-money  market debt  instruments  that had a maturity of 397 days or
         less  when-issued  and which have a  remaining  maturity  of 60 days or
         less.

      |_| The following securities are valued at cost, adjusted for amortization
of premiums and accretion of discounts:

(1)      money market 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

(2)      debt  instruments  held by a money  market  fund that have a  remaining
         maturity of 397 days or less.

      |_| 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,  a  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).

      In the case of municipal  securities,  when last sale  information  is not
generally available,  the Manager may use pricing services approved by the Board
of Trustees.  The pricing service may use "matrix" comparisons to the prices for
comparable instruments on the basis of quality,  yield, maturity.  Other special
factors may be involved (such as the  tax-exempt  status of the interest paid by
municipal  securities).  The Manager  will  monitor the  accuracy of the pricing
services.  That  monitoring  may include  comparing  prices  used for  portfolio
valuation to actual sales prices of selected securities.

      Puts,  calls,  interest rate futures and municipal  bond index futures are
valued at the last sale 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, they shall
be valued at 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.  If not,  the 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 by
the mean  between  "bid" and "asked"  prices  obtained  by the Manager  from two
active  market  makers.  In certain  cases that may be at 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.  An
equivalent credit is included in the liability  section.  The credit is adjusted
("marked-to-market")  to reflect the  current  market  value of the  option.  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 premium paid by the Fund.

How to Sell Shares

The information  below supplements the terms and conditions for redeeming shares
set forth in the Prospectus.

Checkwriting.  When a check is presented to the Fund's 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 to receive  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  listed on the check or at the Fund's  custodian  bank.
That 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.

      In choosing to take advantage of the Checkwriting privilege by signing the
Account  Application or by completing a Checkwriting  card,  each individual who
signs:

(1)      for  individual  accounts,  represents  that  they  are the  registered
         owner(s) of the shares of the Fund in that account;

(2)      for accounts for corporations, partnerships, trusts and other entities,
         represents that they are an officer,  general partner, trustee or other
         fiduciary or agent, as applicable,  duly authorized to act on behalf of
         such registered owner(s);

(3)      authorizes  the Fund, its Transfer Agent and any bank through which the
         Fund's drafts  (checks) are payable to pay all checks drawn on the Fund
         account of such  person(s) and to redeem a sufficient  amount of shares
         from that account to cover payment of each check;

(4)      specifically  acknowledges  that if they choose to permit  checks to be
         honored if there is 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 the
         account,  even if that account is  registered in the names of more than
         one  person  or more  than  one  authorized  signature  appears  on the
         Checkwriting card or the Application, as applicable;

(5)      understands  that  the  Checkwriting  privilege  may be  terminated  or
         amended at any time by the Fund and/or the Fund's bank; and

(6)      acknowledges  and agrees that neither the Fund nor its bank shall incur
         any  liability  for  that  amendment  or  termination  of  checkwriting
         privileges or for redeeming shares to pay checks reasonably believed by
         them to be genuine, or for returning or not paying checks that have not
         been accepted for any reason.

Reinvestment Privilege.  Within six months of a redemption,  a shareholder may
reinvest all or part of the redemption proceeds of:

 |_|  Class A shares  purchased  subject to an initial  sales  charge or Class A
      shares on which a contingent deferred sales charge was paid, or

 |_|  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.  Reinvestment
will be at the net asset value next computed  after the Transfer  Agent receives
the  reinvestment  order.  The shareholder  must ask the Transfer Agent for that
privilege at the time of reinvestment.  This privilege does not apply to Class C
shares.  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.

      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.

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
Fund 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.

      The Fund has elected to be  governed  by Rule 18f-1  under the  Investment
Company Act.  Under that rule,  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 Fund will value  securities  used to pay redemptions in
kind  using the same  method  the Fund uses to value  its  portfolio  securities
described  above  under  "Determination  of Net Asset  Values Per  Share."  That
valuation will be made as of the time the redemption price is determined.

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 $200 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 such shares has fallen
below the stated minimum solely as a result of market fluctuations. If the Board
exercises  this  right,  it may also fix the  requirements  for any notice to be
given to the  shareholders  in question  (not less than 30 days).  The Board may
alternatively  set  requirements for the shareholder to increase the investment,
or set other terms and conditions so that the shares would not be  involuntarily
redeemed.

Transfers of Shares. A transfer of shares to a different  registration is not an
event that  triggers  the payment of sales  charges.  Therefore,  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.  It does not matter
whether the transfer occurs by absolute assignment,  gift or bequest, as long as
it does not involve,  directly or indirectly,  a public sale of the shares. When
shares  subject to a  contingent  deferred  sales  charge are  transferred,  the
transferred shares will remain subject to the contingent  deferred sales charge.
It  will  be  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 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.  Shareholders  should  contact  their
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.  However, 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, the Exchange closes at 4:00 P.M., but
may do so  earlier  on  some  days.  Additionally,  the  order  must  have  been
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.  The  signature(s)  of the  registered  owners  on the  redemption
documents must be guaranteed 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
(having  a  value  of at  least  $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.  Payments must also be sent to the address of record for
the account and the address must not have 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
Account Application or by signature-guaranteed instructions sent to the Transfer
Agent.  Shares are normally  redeemed  pursuant to an Automatic  Withdrawal Plan
three  business  days  before  the  payment  transmittal  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.  The
Fund reserves the right to amend, suspend or discontinue offering these 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 Appendix C below).

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

      |X|  Automatic  Exchange  Plans.  Shareholders  can authorize the Transfer
Agent 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.
Instructions  should  be  provided  on  the   OppenheimerFunds   Application  or
signature-guaranteed instructions.  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.

      |X| Automatic  Withdrawal Plans. Fund shares will be redeemed as necessary
to meet  withdrawal  payments.  Shares  acquired  without a sales charge will be
redeemed  first.  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
these plans should not be considered as a yield or income on your investment.

      The Transfer Agent will  administer the  investor's  Automatic  Withdrawal
Plan as agent for the  shareholder(s)  (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 not taken by the Transfer  Agent in good faith to administer the
Plan. Share 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.

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

      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 after 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 to redeem all, or any part of, the
shares held under the Plan.  That  notice  must be in proper form in  accordance
with the requirements of the then-current  Prospectus of the Fund. In that case,
the Transfer  Agent will redeem the number of shares  requested at the net asset
value  per  share  in  effect  and will  mail a check  for the  proceeds  to the
Planholder.

      The Planholder may terminate a Plan at any time by writing to the Transfer
Agent.  The Fund may also give  directions to the Transfer  Agent to terminate a
Plan. The Transfer Agent will also terminate a Plan upon its receipt of evidence
satisfactory  to it that the  Planholder  has died or is legally  incapacitated.
Upon  termination of a Plan by the Transfer Agent or the Fund,  shares that have
not  been  redeemed  will  be  held in  uncertificated  form in the  name of the
Planholder. The account will continue as a dividend-reinvestment, uncertificated
account unless and until proper  instructions  are received from the Planholder,
his or her executor or guardian, or another 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.  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 Oppenheimer funds that have a
single class  without a class  designation  are deemed "Class A" shares for this
purpose.  You can obtain a current list showing  which funds offer which classes
by calling the Distributor at 1-800-525-7048.

      |_| All of the  Oppenheimer  funds currently 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.

      |_| Oppenheimer  Main Street  California  Municipal Fund currently  offers
only 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.

      |_|   Class  Y  shares  of   Oppenheimer   Real   Asset   Fund  are  not
exchangeable.

      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.  They may also be used to
purchase  shares of  Oppenheimer  funds subject to a contingent  deferred  sales
charge.

      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 30 days 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.  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.  If  requested,  they must
supply proof of entitlement to this privilege.

      For accounts established on or before March 8, 1996 holding Class M shares
of Oppenheimer Convertible Securities Fund, Class M shares can be exchanged only
for Class A shares of other  Oppenheimer  funds.  Exchanges to Class M shares of
Oppenheimer  Convertible  Securities  Fund are permitted  from Class A shares of
Oppenheimer  Money Market Fund,  Inc. or  Oppenheimer  Cash  Reserves  that were
acquired by exchange of Class M shares.  No other exchanges may be made to Class
M shares.

      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.

      |X| How Exchanges Affect Contingent  Deferred Sales Charges. 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 18
months of the end of the calendar month of the initial purchase of the exchanged
Class A shares,  the Class A contingent  deferred sales charge is imposed on the
redeemed  shares.  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.  Before  exchanging
shares,  shareholders  should take into  account how the exchange may affect 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 which class of shares they wish to exchange.

      |X| Limits on Multiple  Exchange  Orders.  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.

      |X| Telephone  Exchange Requests.  When exchanging shares by telephone,  a
shareholder  must have an existing  account in the fund to which the exchange is
to be made.  Otherwise,  the  investors  must obtain a  Prospectus  of that fund
before the exchange request may be submitted.  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.

      |X| Processing  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 Fund may  refuse  the
request.

      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.

      The different  Oppenheimer  funds  available  for exchange have  different
investment objectives,  policies and risks. 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 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,  or as otherwise
described in "How to Buy Shares."  Daily  dividends will not be declared or paid
on newly purchased  shares until such time as 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 declared on
shares  repurchased  by a dealer or broker for three business days following the
trade  date (that is, up to and  including  the day prior to  settlement  of the
repurchase).  If all shares in an account are redeemed, all dividends accrued on
shares  of the  same  class  in the  account  will be  paid  together  with  the
redemption proceeds.

      The Fund's  practice of attempting to pay dividends on Class A shares at a
constant  level  requires  the Manager to monitor the Fund's  portfolio  and, if
necessary, to select higher-yielding securities when it is deemed appropriate to
seek income at the level  needed to meet the target.  Those  securities  must be
within  the  Fund's  investment  parameters,  however.  The Fund  expects to pay
dividends  at a  targeted  level  from  its  net  investment  income  and  other
distributable income without any impact on the net asset values per share.

      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.
Reinvestment  will be made 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.  Unclaimed  accounts may be subject to state  escheatment
laws, and the Fund and the Transfer Agent will not be liable to  shareholders or
their representatives for compliance with those laws in good faith.

      The amount of a distribution  paid on a class of shares 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.  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.  That is due to the  effect of the
asset-based  sales charge on Class B and Class C shares.  Those  dividends  will
also  differ in amount as a  consequence  of any  difference  in net asset value
among the different class of shares.

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 that
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  that are free from Federal
income  taxes.  This  allocation  will  be  made  by the  use of one  designated
percentage  applied uniformly to all income dividends paid during the Fund's tax
year.  That  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. 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.

      A shareholder receiving a dividend from income earned by the Fund from one
or more of the  following  sources  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:

(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.

      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.

      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.  That qualification  enables the Fund
to "pass through" its income and realized capital gains to shareholders  without
having to pay tax on them. 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  qualifies.  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  and will receive no tax  deduction for
payments of dividends and distributions made to shareholders.

      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. If it
does not, the Fund must pay an excise tax on the amounts not distributed.  It is
presently  anticipated that the Fund will meet those requirements.  However, the
Fund's Board of Trustees and the Manager  might  determine in a particular  year
that it would be in the best interest of shareholders 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 capital gains  distributions in shares of the same
class of any of the other Oppenheimer  funds listed above.  Reinvestment will be
made at net  asset  value  without  sales  charge.  To elect  this  option,  the
shareholder  must notify the Transfer Agent in writing and must have an existing
account in the fund selected for  reinvestment.  Otherwise the shareholder  must
first obtain a  prospectus  for that fund and an  application  from the Transfer
Agent 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/or  distributions  from certain of the
other  Oppenheimer  funds  may be  invested  in  shares of this Fund on the same
basis.

Additional Information About the Fund

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

The Transfer Agent. The Fund's Transfer Agent,  OppenheimerFunds  Services, is a
division  of  the  Manager.   It  is  responsible  for  maintaining  the  Fund's
shareholder  registry  and  shareholder   accounting  records,  and  for  paying
dividends  and  distributions  to  shareholders  of the  Fund.  It also  handles
shareholder servicing and administrative  functions.  It is paid on an "at-cost"
basis.

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  and handling the delivery of such  securities to and from
the Fund.  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.  Those
uninsured balances may at times be substantial.

Independent Auditors.  Deloitte & Touche LLP are the independent auditors of the
Fund. They audit 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, 1998, the related statement of operations for the year then ended,
the statements of changes in net assets for the years ended September 30, 1998
and 1997, and the financial highlights for the period October 1, 1993 to
September 30, 1998. 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, 1998, 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, 1998, 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.

</TABLE>

1. 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 $11,364,550 or 8.23% of the
Fund's net assets as of September 30, 1998.
 
2. For zero coupon bonds, the interest rate shown is the effective yield on the
date of purchase.

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 $3,500,092 or 2.53% of the Fund's net
assets as of September 30, 1998.

4. Identifies issues considered to be illiquid or restricted--See Note 6 of
Notes to Financial Statements.

5. Variable rate security. The interest rate, which is based on specific, or an
index of, market interest rates, is subject to change periodically and is the
effective rate on September 30, 1998.

As of September 30, 1998, securities subject to the alternative minimum tax
amount to $29,561,410 or 21.40% of the Fund's net assets.

See accompanying Notes to Financial Statements.

================================================================================
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 a high level of current income exempt
from Federal income tax. The Fund will, under normal market conditions, invest
at least 80% of its total assets in investment-grade Municipal Securities. 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.

- --------------------------------------------------------------------------------
Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated daily to
each class of shares based upon the relative proportion of net assets
represented by such class. Operating expenses directly attributable to a
specific class are charged against the operations of that class.

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

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. The character of the distributions made during the year from net
investment income or net realized gains may differ from its ultimate
characterization for federal income tax purposes. Also, due to timing of
dividend distributions, the fiscal year in which amounts are distributed may
differ from the fiscal year in which the income or realized gain was recorded by
the Fund.

            The Fund adjusts the classification of distributions to shareholders
to reflect the differences between financial statement amounts and distributions
determined in accordance with income tax regulations. Accordingly, during the
year ended September 30, 1998, amounts have been reclassified to reflect a
decrease in undistributed net investment income of $671,664, a decrease in
accumulated net realized loss on investments of $321,410, and an increase in
paid-in capital of $350,254.

- --------------------------------------------------------------------------------
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. As of November
4, 1997, in order to conform book and tax bases, the Fund began amortization of
premiums on securities for book purposes. Such cumulative change was limited to
a reclassification adjustment and had no impact on net assets or total increase
(decrease) in net assets. Accordingly, during the year ended September 30, 1998,
amounts have been reclassified to reflect an increase in unrealized appreciation
of $671,664. Paid-in capital was decreased by the same amount. 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.

================================================================================
2. Shares of Beneficial Interest
The Fund has authorized an unlimited number of no par value shares of beneficial
interest of each class. Transactions in shares of beneficial interest were as

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% of the first
$100 million of average annual net assets, 0.45% of the next $150 million,
0.425% of the next $250 million and 0.40% of average annual net assets in excess
of $500 million. The Fund's management fee for the year ended September 30, 1998
was 0.49% of average annual net assets for Class A, Class B and Class C shares.

            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, 1998, commissions (sales charges
paid by investors) on sales of Class A shares totaled $303,538, of which $55,035
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 $166,461 and $74,498, respectively, of which $3,386 was
paid to an affiliated broker/dealer for Class C shares. During the year ended
September 30, 1998, OFDI received contingent deferred sales charges of $11,878
and $12,321, respectively, upon redemption of Class B and Class C shares, as
reimbursement for sales commissions advanced by OFDI at the time of sale of such
shares.

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

            The Fund has adopted a Service Plan for Class A shares to reimburse
OFDI for a portion of its costs incurred in connection with the personal service
and maintenance of shareholder accounts that hold Class A shares. Reimbursement
is made quarterly at an annual rate that may not exceed 0.25% of the average
annual net assets of Class A shares of the Fund. OFDI uses the service fee to
reimburse brokers, dealers, banks and other financial institutions quarterly for
providing personal service and maintenance of accounts of their customers that
hold Class A shares. During the year ended September 30, 1998, OFDI paid $30,812
to an affiliated broker/dealer as reimbursement for Class A personal service and
maintenance expenses.

The Fund has adopted Distribution and Service Plans for Class B and Class C
shares to compensate OFDI for its costs in distributing Class B and Class C
shares and servicing accounts. Under the Plans, the Fund pays OFDI an annual
asset-based sales charge of 0.75% per year on Class B and Class C shares for its
services rendered in distributing Class B and Class C shares. OFDI also receives
a service fee of 0.25% per year to compensate dealers for providing personal
services for accounts that hold Class B and Class C shares. Each fee is computed
on the average annual net assets of Class B or Class C shares, determined as of
the close of each regular business day. During the year ended September 30,
1998, OFDI paid $3,923, to an affiliated broker/dealer as compensation for Class
C personal service and maintenance expenses and retained $94,754 and $84,398,
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. As of September 30, 1998, OFDI had incurred excess distribution and
servicing costs of $273,649 for Class B and $259,730 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. Illiquid and Restricted Securities

As of September 30, 1998, investments in securities included issues that are
illiquid or restricted. Restricted securities are often purchased in private
placement transactions, are not registered under the Securities Act of 1933, may
have contractual restrictions on resale, and are valued under methods approved
by the Board of Trustees as reflecting fair value. A security may also be
considered illiquid if it lacks a readily available market or if its valuation
has not changed for a certain period of time. The Fund intends to invest no more
than 10% of its net assets (determined at the time of purchase and reviewed
periodically) in illiquid or restricted securities. Certain restricted
securities, eligible for resale to qualified institutional investors, are not
subject to that limit. The aggregate value of illiquid or restricted securities
subject to this limitation at September 30, 1998, was $3,128,766, which
represents 2.27% of the Fund's net assets.

================================================================================
7. Bank Borrowings

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

            The Fund had no borrowings outstanding during the year ended
September 30, 1998.

                       MUNICIPAL BOND RATINGS DEFINITIONS
- ------------------------------------------------------------------------------

Below are summaries of the rating definitions used by the  nationally-recognized
rating agencies listed below for municipal  securities.  Those ratings represent
the opinion of the agency as to the credit quality of issues that they rate. The
summaries below are based upon  publicly-available  information  provided by the
rating organizations.

Moody's Investors Service, Inc.
- ------------------------------------------------------------------------------

Long-Term Bond Ratings

Aaa: Bonds rated Aaa are judged to be the best quality.  They carry the smallest
degree of investment risk.  Interest  payments are protected by a large or by an
exceptionally   stable  margin  and  principal  is  secure.  While  the  various
protective  elements are likely to change,  the changes that can be expected are
most unlikely to impair the fundamentally strong position of such issues.

Aa: Bonds rated Aa are judged to be of high quality by all  standards.  Together
with the Aaa group,  they comprise what are generally known as high-grade bonds.
They are rated lower than the best bonds because  margins of protection  may not
be as large as with Aaa securities or fluctuation of protective  elements may be
of  greater  amplitude  or there may be other  elements  present  which make the
long-term risks appear somewhat larger than those of Aaa securities.

A: Bonds rated A possess  many  favorable  investment  attributes  and are to be
considered  as  upper-medium  grade  obligations.  Factors  giving  security  to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment sometime in the future.

Baa: Bonds rated Baa are considered medium grade obligations;  that is, 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 have  speculative
characteristics as well.

Ba: Bonds rated Ba are judged to have speculative elements.  Their future cannot
be  considered  well-assured.  Often the  protection  of interest and  principal
payments may be very moderate and not well safeguarded  during both good and bad
times over the  future.  Uncertainty  of  position  characterizes  bonds in this
class.

B:  Bonds  rated B  generally  lack  characteristics  of  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.

Caa:  Bonds rated Caa are of poor  standing and may be in default or there may
be present elements of danger with respect to principal or interest.

Ca:  Bonds rated Ca  represent  obligations  which are  speculative  in a high
degree and are often in default or have other marked shortcomings.

C: Bonds  rated C are the lowest  class of rated  bonds and can be  regarded  as
having extremely poor prospects of ever attaining any real investment standing.

Con. (...):  Bonds for which the security  depends on the completion of some act
or the  fulfillment of some condition are rated  conditionally.  These bonds are
secured by (a) earnings of projects under construction, (b) earnings of projects
unseasoned in operating  experience,  (c) rentals that begin when facilities are
completed,   or  (d)   payments  to  which  some  other   limitation   attaches.
Parenthetical   rating  denotes  probable  credit  stature  upon  completion  of
construction  or elimination of basis of condition.  Moody's  applies  numerical
modifiers 1, 2, and 3 in each generic rating classification from Aa through Caa.
The modifier "1" indicates  that the  obligation  ranks in the higher end of its
category;  the modifier "2"  indicates a mid-range  ranking and the modifier "3"
indicates a ranking in the lower end of the category.  Advanced  refunded issues
that are secured by certain assets are identified with a # symbol.

Short-Term Ratings - U.S. Tax-Exempt Municipals

There are four ratings  below for  short-term  obligations  that are  investment
grade.  Short-term speculative  obligations are designated SG. For variable rate
demand obligations,  a two-component rating is assigned. The first (MIG) element
represents  an  evaluation  by  Moody's of the  degree of risk  associated  with
scheduled  principal and interest  payments,  and the other (VMIG) represents an
evaluation of the degree of risk associated with the demand feature.

MIG 1/VMIG 1: Denotes best quality.  There is strong  protection by  established
cash flows, superior liquidity support or demonstrated broad-based access to the
market for refinancing..

MIG 2/VMIG 2: Denotes high quality. Margins of protection are ample although not
as large as in the preceding group.

MIG 3/VMIG 3: Denotes favorable quality. All security elements are accounted for
but there is lacking the undeniable strength of the preceding grades.  Liquidity
and cash flow  protection  may be narrow and market  access for  refinancing  is
likely to be less well established.

MIG 4/VMIG 4: Denotes adequate quality. Protection commonly regarded as required
of  an   investment   security  is  present  and  although  not   distinctly  or
predominantly speculative, there is specific risk.

SG:  Denotes  speculative  quality.  Debt  instruments  in this  category lack
margins of protection.


Standard & Poor's Rating Services
- ------------------------------------------------------------------------------

Long-Term Credit Ratings

AAA: Bonds rated "AAA" have the highest rating  assigned by Standard & Poor's.
The obligor's  capacity to meet its financial  commitment on the obligation is
extremely strong.

AA: Bonds rated "AA" differ from the highest rated  obligations  only in small
degree.  The  obligor's  capacity  to meet  its  financial  commitment  on the
obligation is very strong.

A: Bonds rated "A" are somewhat more  susceptible to adverse  effects of changes
in  circumstances  and economic  conditions  than  obligations  in  higher-rated
categories.  However, the obligor's capacity to meet its financial commitment on
the obligation is still strong.

BBB: Bonds rated BBB exhibit adequate protection  parameters.  However,  adverse
economic  conditions  or  changing  circumstances  are more  likely to lead to a
weakened  capacity  of the  obligor  to meet  its  financial  commitment  on the
obligation.

Bonds rated BB, B, CCC, CC and C are regarded as having significant  speculative
characteristics. BB indicates the least degree of speculation and C the highest.
While  such   obligations   will  likely  have  some   quality  and   protective
characteristics,  these  may be  outweighed  by  large  uncertainties  or  major
exposures to adverse conditions.

BB: Bonds rated BB are less  vulnerable  to  nonpayment  than other  speculative
issues. However, these face major uncertainties or exposure to adverse business,
financial,  or economic conditions which could lead to the obligor's  inadequate
capacity to meet its financial commitment on the obligation.

B: A bond rated B is more vulnerable to nonpayment than an obligation  rated BB,
but the obligor  currently has the capacity to meet its financial  commitment on
the obligation.

CCC: A bond rated CCC is currently  vulnerable to  nonpayment,  and is dependent
upon favorable business,  financial,  and economic conditions for the obligor to
meet its  financial  commitment  on the  obligation.  In the  event  of  adverse
business,  financial or economic  conditions,  the obligor is not likely to have
the capacity to meet its financial commitment on the obligation.

CC:  An obligation rated CC is currently highly vulnerable to nonpayment.

C: The C rating may used where a  bankruptcy  petition has been filed or similar
action has been taken, but payments on this obligation are being continued.

D: Bonds rated D are in  default.  Payments  on the  obligation  are not being
made on the date due.

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. The
"r" symbol is attached to the ratings of instruments with significant  noncredit
risks.

Short-Term Issue Credit Ratings

A-1: Rated in the highest category. The obligor's capacity to meet its financial
commitment on the obligation is strong.  Within this  category,  a plus (+) sign
designation  indicates the issuer's capacity to meet its financial obligation is
very strong.

A-2:  Obligation is somewhat more  susceptible to the adverse effects of changes
in  circumstances  and economic  conditions  than  obligations  in higher rating
categories.  However, the obligor's capacity to meet its financial commitment on
the obligation is satisfactory.

A-3:  Exhibits  adequate  protection  parameters.   However,   adverse  economic
conditions  or  changing  circumstances  are more  likely to lead to a  weakened
capacity of the obligor to meet its financial commitment on the obligation.

B:  Regarded  as having  significant  speculative  characteristics.  The obligor
currently has the capacity to meet its financial  commitment on the  obligation.
However, it faces major ongoing  uncertainties which could lead to the obligor's
inadequate capacity to meet its financial commitment on the obligation.

C:  Currently  vulnerable  to  nonpayment  and  is  dependent  upon  favorable
business,  financial,  and  economic  conditions  for the  obligor to meet its
financial commitment on the obligation.

D: In payment  default.  Payments on the obligation  have not been made on the
due date. The rating may also be used if a bankruptcy  petition has been filed
or similar actions jeopardize payments on the obligation.


Fitch IBCA, Inc.
- ------------------------------------------------------------------------------

International Long-Term Credit Ratings

Investment Grade:
AAA:  Highest Credit Quality.  "AAA" ratings denote the lowest  expectation of
credit  risk.  They  are  assigned  only in the case of  exceptionally  strong
capacity for timely payment of financial commitments.  This capacity is highly
unlikely to be adversely affected by foreseeable events.

AA: Very High Credit  Quality.  "AA" ratings denote a very low  expectation of
credit  risk.  They  indicate a very  strong  capacity  for timely  payment of
financial  commitments.  This  capacity  is not  significantly  vulnerable  to
foreseeable events.

A: High Credit  Quality.  "A" ratings denote a low expectation of credit risk.
The  capacity  for  timely  payment of  financial  commitments  is  considered
strong.  This capacity  may,  nevertheless,  be more  vulnerable to changes in
circumstances or in economic conditions than is the case for higher ratings.

BBB: Good Credit  Quality.  "BBB"  ratings  indicate that there is currently a
low  expectation  of credit risk. The capacity for timely payment of financial
commitments is considered  adequate,  but adverse changes in circumstances and
in economic  conditions are more likely to impair this  capacity.  This is the
lowest investment-grade category.

Speculative Grade:

BB:  Speculative.  "BB" ratings indicate that there is a possibility of credit
risk  developing,  particularly as the result of adverse  economic change over
time.  However,  business or financial  alternatives may be available to allow
financial commitments to be met.

B: Highly  Speculative.  "B" ratings indicate that significant  credit risk is
present,  but a limited margin of safety  remains.  Financial  commitments are
currently  being met.  However,  capacity for continued  payment is contingent
upon a sustained, favorable business and economic environment.

CCC, CC C: High  Default  Risk.  Default is a real  possibility.  Capacity for
meeting  financial  commitments  is solely reliant upon  sustained,  favorable
business or economic  developments.  A "CC" rating  indicates  that default of
some kind appears probable. "C" ratings signal imminent default.

DDD, DD, and D: Default.  Securities are not meeting  current  obligations and
are  extremely  speculative.   "DDD"  designates  the  highest  potential  for
recovery of amounts outstanding on any securities involved.

Plus (+) and  minus  (-)  signs  may be  appended  to a rating  symbol to denote
relative status within the rating  category.  Plus and minus signs are not added
to the "AAA" category or to categories below "CCC."

International Short-Term Credit Ratings

F1: Highest credit quality.  Strongest capacity for timely payment.  May have an
added "+" to denote exceptionally strong credit feature.

F2: Good credit quality.  A satisfactory  capacity for timely  payment,  but the
margin of safety is not as great as in higher ratings.

F3: Fair credit  quality.  Capacity  for timely  payment is  adequate.  However,
near-term adverse changes could result in a reduction to non-investment grade.

B:  Speculative.  Minimal capacity for timely payment,  plus  vulnerability to
near-term adverse changes in financial and economic conditions.

C:  High  default  risk.   Default  is  a  real   possibility,   Capacity  for
meeting  financial  commitments is solely reliant upon a sustained,  favorable
business and economic environment.

D:     Default. Denotes actual or imminent payment default.

Duff & Phelps Credit Rating Co. Ratings

Long-Term Debt and Preferred Stock

AAA:  Highest  credit  quality.  The risk factors are  negligible,  being only
slightly more than for risk-free U.S. 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 in periods of greater 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 likely to meet obligations when
due. Present or prospective  financial protection factors fluctuate according to
industry  conditions.  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 arrearages.

Short-Term Debt:

                                   High Grade:
D-1+:  Highest  certainty of timely  payment.  Safety is just below  risk-free
U.S. Treasury short-term debt.

D-1: Very high certainty of timely payment. Risk factors are minor.

D-1-: High certainty of timely payment. Risk factors are very small.

Good Grade:
D-2: Good certainty of timely payment. Risk factors are small.

Satisfactory Grade:
D-3:  Satisfactory  liquidity and other protection  factors qualify issues as to
investment grade. Risk factors are larger and subject to more variation.
Nevertheless, timely payment is expected.

Non-Investment Grade:
D-4: Speculative  investment  characteristics.  Liquidity is not sufficient to
insure against disruption in debt service.

Default:
D-5: Issuer failed to meet scheduled principal and/or interest payments.

OppenheimerFunds Special Sales Charge Arrangements and Waivers
- ------------------------------------------------------------------------------

      In certain  cases,  the initial  sales charge that applies to purchases of
Class A shares of the Oppenheimer funds or the contingent  deferred sales charge
that may  apply to Class A,  Class B or Class C shares  may be  waived.  That is
because of the economies of sales  efforts  realized by the  Distributor  or the
dealers or other financial institutions offering those shares to certain classes
of investors or in certain transactions.

      Not all  waivers  apply to all funds.  For  example,  waivers  relating to
Retirement Plans do not apply to Oppenheimer  municipal funds, because shares of
those funds are not available for purchase by or on behalf of retirement  plans.
Other waivers apply only to  shareholders of certain funds that were merged into
or became Oppenheimer funds.

      For the  purposes  of  some  of the  waivers  described  below  and in the
Prospectus and Statement of Additional Information of the applicable Oppenheimer
funds,  the term  "Retirement  Plan" refers to the following types of plans: (1)
plans qualified under Sections 401(a) or 401(k) of the Internal
         Revenue Code,
(2) non-qualified  deferred  compensation plans, (3) employee benefit plans1 (4)
Group  Retirement  Plans2 (5)  403(b)(7)  custodial  plan accounts (6) SEP-IRAs,
SARSEPs or SIMPLE plans

         The  interpretation  of these  provisions as to the  applicability of a
waiver in a  particular  case is  determined  solely by the  Distributor  or the
Transfer  Agent of the fund.  These  waivers  and  special  arrangements  may be
amended or terminated at any time by the applicable Fund and/or the Distributor.
Waivers  that apply at the time shares are  redeemed  must be  requested  by the
shareholder and/or dealer in the redemption request.
- --------------
1. An "employee  benefit plan" means any plan or arrangement,  whether or not it
   is "qualified" under the Internal Revenue Code, under which Class A shares of
   an  Oppenheimer  fund  or  funds  are  purchased  by  a  fiduciary  or  other
   administrator  for the account of participants  who are employees of a single
   employer or of affiliated employers.  These may include, for example, medical
   savings accounts, payroll deduction plans or similar plans. The fund accounts
   must be registered in the name of the fiduciary or  administrator  purchasing
   the shares for the benefit of participants in the plan.
2. The term  "Group  Retirement  Plan"  means  any  qualified  or  non-qualified
   retirement  plan  for  employees  of a  corporation  or sole  proprietorship,
   members and  employees of a partnership  or  association  or other  organized
   group of persons  (the  members of which may include  other  groups),  if the
   group has made special  arrangements  with the Distributor and all members of
   the group  participating  in (or who are eligible to participate in) the plan
   purchase  Class A shares  of an  Oppenheimer  fund or funds  through a single
   investment dealer,  broker or other financial  institution  designated by the
   group.  Such plans  include 457 plans,  SEP-IRAs,  SARSEPs,  SIMPLE plans and
   403(b) plans other than plans for public  school  employees.  The term "Group
   Retirement Plan" also includes  qualified  retirement plans and non-qualified
   deferred  compensation  plans  and IRAs  that  purchase  Class A shares of an
   Oppenheimer fund or funds through a single investment dealer, broker or other
   financial institution that has made special arrangements with the Distributor
   enabling  those  plans to  purchase  Class A shares  at net  asset  value but
   subject to the Class A contingent deferred sales charge.

- ------------------------------------------------------------------------------
Applicability of Class A Contingent Deferred Sales Charges in Certain Cases
- ------------------------------------------------------------------------------

Purchases of Class A Shares of Oppenheimer Funds That Are Not Subject to Initial
Sales Charge but May Be Subject to the Class A Contingent  Deferred Sales Charge
(unless a waiver applies).

      There is no initial  sales charge on purchases of Class A shares of any of
the Oppenheimer funds in the cases listed below. However, these purchases may be
subject to the Class A contingent  deferred  sales charge if redeemed  within 18
months of the end of the calendar month of their  purchase,  as described in the
Prospectus (unless a waiver described  elsewhere in this Appendix applies to the
redemption).  Additionally,  on these  purchases  the  Distributor  will pay the
applicable  commission  described  in the  Prospectus  under "Class A Contingent
Deferred Sales Charge":
      |_|   Purchases of Class A shares aggregating $1 million or more.
o     Purchases by  a Retirement Plan that:
(1)   buys shares costing $500,000 or more, or
(2)   has,  at the time of  purchase,  100 or more  eligible  participants  or
            total plan assets of $500,000 or more, or
(3)         certifies  to the  Distributor  that it projects to have annual plan
            purchases of $200,000 or more.
o     Purchases  by  an   OppenheimerFunds-sponsored   Rollover  IRA,  if  the
         purchases are made:
(1)         through a broker, dealer, bank or registered investment adviser that
            has  made  special  arrangements  with  the  Distributor  for  those
            purchases, or
(2)         by a direct rollover of a distribution  from a qualified  Retirement
            Plan if the administrator of that Plan has made special arrangements
            with the Distributor for those purchases.
o        Purchases  of Class A shares by  Retirement  Plans that have any of the
         following record-keeping arrangements:
(1)   The record  keeping is performed by Merrill Lynch Pierce Fenner & Smith,
            Inc.  ("Merrill  Lynch")  on  a  daily  valuation  basis  for  the
            Retirement   Plan.   On  the  date  the  plan  sponsor  signs  the
            record-keeping  service  agreement  with Merrill  Lynch,  the Plan
            must have $3 million or more of its assets  invested in (a) mutual
            funds,  other than those advised or managed by Merrill Lynch Asset
            Management,  L.P.  ("MLAM"),  that  are  made  available  under  a
            Service  Agreement  between  Merrill  Lynch and the mutual  fund's
            principal  underwriter  or  distributor,  and (b) funds advised or
            managed by MLAM (the funds  described  in (a) and (b) are referred
            to as "Applicable Investments").
(2)   The record  keeping  for the  Retirement  Plan is  performed  on a daily
            valuation  basis by a record  keeper  whose  services are provided
            under a contract or arrangement  between the  Retirement  Plan and
            Merrill  Lynch.  On the date the plan  sponsor  signs  the  record
            keeping service  agreement with Merrill Lynch,  the Plan must have
            $3 million or more of its assets  (excluding  assets  invested  in
            money market funds) invested in Applicable Investments.
(3)         The record keeping for a Retirement  Plan is handled under a service
            agreement  with Merrill Lynch and on the date the plan sponsor signs
            that agreement, the Plan has 500

            or more  eligible  employees  (as  determined by the Merrill Lynch
            plan conversion manager).

            Waivers of Class A Sales Charges of Oppenheimer Funds
- ------------------------------------------------------------------------------

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  (and  no  commissions  are  paid  by the  Distributor  on such
purchases):
      |_|  The Manager or its affiliates.
      |_| Present or former  officers,  directors,  trustees and employees  (and
their  "immediate  families") of the Fund, the Manager and its  affiliates,  and
retirement plans  established by them for their  employees.  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;  relatives by

insurance  companies having an agreement with the Manager or the Distributor for
that purpose.
      |_| 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.
      |_|  Employees  and  registered  representatives  (and their  spouses)  of

for certain  persons who were  shareholders of the former Quest for Value Funds.
To be eligible,  those persons must have been shareholders on November 24, 1995,
when OppenheimerFunds,  Inc. became the investment advisor to those former Quest
for Value Funds. Those funds include:

      Oppenheimer Quest Value Fund, Inc., Oppenheimer Quest Balanced Value Fund,
      Oppenheimer  Quest  Opportunity  Value Fund,  Oppenheimer  Quest Small Cap
      Value Fund and Oppenheimer Quest Global Value Fund, Inc.

sales charges  described in this Appendix apply to shares of an Oppenheimer fund
that are either:

Former Quest for Value Fund merged.  Those shares must have been purchased on or
after March 6, 1995, but prior to November 24, 1995:

initial  sales  charge,  but subject to the Class A  contingent  deferred  sales
charge that was in effect  prior to March 18,  1996 (the "prior  Class A CDSC").
Under the prior Class A CDSC,  if any of those  shares are  redeemed  within one
year of purchase, they will be assessed a 1% contingent deferred sales charge on
an amount equal to the current  market value or the original  purchase  price of
the shares  sold,  whichever  is smaller  (in such  redemptions,  any shares not

         on Combined  Purchases or Rights of Accumulation,  who still hold those
         shares in that Fund or other Former Connecticut Mutual Funds, and
(2)      persons whose intended purchases under a Statement of Intention entered
         into prior to March 18, 1996,  with the former  general  distributor of
         the  Former  Connecticut  Mutual  Funds to  purchase  shares  valued at
         $500,000  or more over a  13-month  period  entitled  those  persons to
         purchase shares at net asset value without being subject to the Class A
         initial sales charge.

      Any of the  Class A shares  of a Fund  and the  other  Former  Connecticut
Mutual  Funds that were  purchased  at net asset value prior to March 18,  1996,
remain  subject  to the prior  Class A CDSC,  or if any  additional  shares  are
purchased by those  shareholders at net asset value pursuant to this arrangement
they will be subject to the prior Class A CDSC.

      |_| Class A Sales Charge Waivers.  Additional Class A shares of a Fund may
be purchased without a sales charge, by a person who was in one (or more) of the
categories  below and acquired Class A shares prior to March 18, 1996, and still
holds Class A shares:  (1) any  purchaser,  provided  the total  initial  amount

(2)      any  participant in a qualified  plan,  provided that the total initial

         Former Connecticut Mutual Funds totaled $500,000 or more;
(3)      Directors  of the  Fund or any one or  more of the  Former  Connecticut
         Mutual Funds and members of their immediate families;
(4)      employee  benefit  plans  sponsored  by  Connecticut  Mutual  Financial
         Services,   L.L.C.  ("CMFS"),  the  prior  distributor  of  the  Former
         Connecticut Mutual Funds, and its affiliated companies;
(5)      one or more  members of a group of at least 1,000  persons (and persons
         who are  retirees  from  such  group)  engaged  in a  common  business,
         profession,  civic or charitable  endeavor or other  activity,  and the
         spouses and minor  dependent  children of such  persons,  pursuant to a
         marketing program between CMFS and such group; and
(6)      an  institution  acting as a fiduciary  on behalf of an  individual  or

         or any one or more of the Former Connecticut Mutual Funds, provided the
         institution had an agreement with CMFS.

      Purchases  of Class A shares  made  pursuant  to (1) and (2)  above may be
subject to the Class A CDSC of the Former  Connecticut  Mutual  Funds  described
above.

charge by any holder of a variable  annuity contract issued in New York State by

About the Fund

The Fund's Objective and Investment Strategies

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

What Does the Fund Invest In? The Fund invests  mainly in  municipal  securities
that pay  interest  exempt from Federal  individual  income tax.  These  include
municipal bonds (which are debt  obligations  having a maturity of more than one
year when  issued),  municipal  notes  (short term  obligations),  interests  in
municipal leases, and tax-exempt commercial paper.

      Under normal market conditions the Fund:
      |_| will invest at least 80% of its assets in  municipal  securities,  
     |_| does not invest more than 10% of its total  assets in  securities  that
are not  "investment  grade"  (which  means  they  are  rated in one of the four
highest  rating  categories  of national  rating  organizations  such as Moody's
Investors Services), and
     |_| will  normally  invest  at  least  65% of its  assets  in  insured  and
"pre-refunded" municipal securities.

      The Fund does not limit its  investments  in  securities  of a  particular
maturity  range.  Therefore  it can  hold  securities  that  have  short or long
maturities.  The Fund can also use hedging  instruments  and certain  derivative
investments  to a  limited  extent  to try to  manage  investment  risks.  These
investments are more fully explained in "About the Fund's Investments," below.

      How Does the Manager  Decide What  Securities to Buy or Sell? In selecting
securities for the Fund, the Manager  currently  looks  nationwide for municipal
securities  by  considering  a variety of factors which may change over time and
may vary in particular cases.

 Currently the Fund's portfolio manager searches for:
      |_|      Insured and pre-refunded securities that offer high income,

      |_|      A wide range of issuers  and  securities  to provide  portfolio
      diversification,

      |_|      Issues having favorable credit characteristics,

o     Special  situations among issuers that provide  opportunities for value,
      and
o     Bonds with protection against being called by the issuer.

Who Is the Fund Designed For? The Fund is designed for investors who are seeking
income  exempt from federal  income  taxes.  It does not seek  capital  gains or
growth. Because it invests in tax-exempt securities, the Fund is not appropriate
for retirement plan accounts or for investors who want to pursue capital growth.

Main Risks of Investing in the Fund

All investments carry risks to some degree.  For bond funds one risk is that the
market prices of the fund's  investments  will fluctuate  when general  interest
rates change (this is known as "interest  rate risk").  Another risk is that the
issuer of the bond will experience financial difficulties and may default on its
obligation 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.

      These risks  collectively form the risk profile of the Fund and can affect
the value of the Fund's investments,  its investment performance, and the prices
of its  shares.  These  risks mean that you can lose money by  investing  in the
Fund. When you redeem your shares,  they may be worth more or less than what you
paid for them.

      The Fund's  investment  Manager,  OppenheimerFunds,  Inc., tries to reduce
risks by diversifying  investments,  by carefully researching  securities before
they are  purchased  and in some  cases by using  hedging  techniques.  However,
changes in the overall market prices of municipal securities and the income they
pay can occur at any time.  The  yield and share  price of the Fund will  change
daily based on changes in interest rates and market conditions,  and in response
to other economic  events.  There is no assurance that the Fund will achieve its
investment objective.

An  investment  in the Fund is not a deposit of any bank,  and is not insured or
guaranteed by the Federal Deposit Insurance  Corporation or any other government
agency.

      |X| Credit Risk.  Municipal  securities are subject to credit risk. Credit
risk  relates  to the  ability  of the issuer of a  municipal  security  to make
interest  and  principal  payments  on the  security  as they become due. If the
issuer fails to pay interest, the Fund's income may be reduced and if the issuer
fails to repay  principal,  the value of that  security and of the Fund's shares
might be reduced.  The Fund's  investments in insured municipal  securities help
reduce this risk.  The Fund limits its  investments  in securities  that are not
investment grade to 10% of its total assets.

      |X| Interest Rate Risks. In addition to credit risks, municipal securities
are subject to changes in value when  prevailing  interest  rates  change.  When
interest rates fall, the values of outstanding  municipal  securities  generally
rise,  and the bonds may sell for more than their  face  amount.  When  interest
rates rise, the values of outstanding  municipal  securities generally fall, and
the bonds may sell at a discount from their face amount.

      The magnitude of these price  changes is generally  greater for bonds with
longer  maturities.  There are no restrictions on the range of maturities of the
municipal securities in which the Fund may invest.  Currently,  the Fund focuses
on long-term  securities to seek higher income. When the average maturity of the
Fund's  portfolio is longer,  its share price will  fluctuate more when interest
rates change.  Insurance on municipal  securities in which the Fund invests does
not insure  against  fluctuations  in the values of the securities or the Fund's
share price.

      |X| There Are Special Risks in Using Derivative Investments.  The Fund can
use derivatives to seek increased  returns or to try to hedge investment  risks.
In general terms, a derivative  investment is an investment contract whose value
depends on (or is derived from) the value of an underlying asset,  interest rate
or index.  Options,  futures,  "inverse  floaters,"  and interest rate swaps are
examples of derivatives the Fund can use.

      If the issuer of the  derivative  investment  does not pay the amount due,
the Fund can lose money on its  investment.  Also,  the  underlying  security or
investment on which the derivative is based,  and the derivative  itself,  might
not perform the way the Manager  expected it to perform.  If that  happens,  the
Fund will get less income than  expected or its share price could  decline.  The
Fund has limits on the amount of particular  types of  derivatives  it can hold.
However,  using  derivatives can cause the Fund to lose money on its investments
and/or increase the volatility of its share prices.

How Risky Is the Fund Overall?  The value of the Fund's investments in municipal
securities  will  change  over time due to a number  of  factors.  They  include
changes in general  bond  market  movements,  the change in value of  particular
bonds  because of an event  affecting the issuer,  or changes in interest  rates
that can affect bond prices  overall.  These changes can affect the value of the
Fund's  investments  and its price per share.  The Fund can invest in derivative
investments.  These  have  additional  risks and can cause  fluctuations  in the
Fund's share prices.

      The Fund's  investments in insured  municipal  securities  help reduce the
risk of loss from a default because  payments of principal and interest on those
securities is insured.  Neither the market value of those securities nor the net
asset  value  of  shares  of  the  Fund  is  insured  or   guaranteed.   In  the
OppenheimerFunds spectrum, the Fund is more conservative with respect to default
risk than some types of taxable bond funds,  such as high yield bond funds,  but
more aggressive than money market funds.

The Fund's Past Performance

The bar chart and table below show one measure of the risks of  investing in the
Fund, by showing changes in the Fund's performance (for its Class A shares) from
year to year for the last ten  calendar  years and by  showing  how the  average
annual  total  returns of the Fund's  shares  compare to those of a  broad-based
market index.  The Fund's past  investment  performance  is not  necessarily  an
indication of how the Fund will perform in the future.

[see appendix to the prospectus]

Sales charges are not included in the  calculations of return in this bar chart,
and if those charges were included the returns would be less than those shown.

During the  10-year  period  shown in the bar chart,  the  highest  return  (not
annualized)  for a calendar  quarter was 7.17% (1st Q '95) and the lowest return
(not annualized) for a calendar quarter was -6.63% (1st Q '94).

The Fund's  average  annual total  returns in the table  include the  applicable
sales charge:  for Class A, the current  maximum  initial sales charge of 4.75%;
for Class B, the applicable  contingent deferred sales charges of 5% (1-year) 2%
(5-years) and 1% (life-of-class);  for Class C, the 1% contingent deferred sales
charge for the 1-year period.

The returns  measure the  performance of a hypothetical  account and assume that
all dividends and capital gains distributions have been reinvested in additional
shares.  Because  the Fund  invests in a variety of  municipal  securities,  the
Fund's  performance is compared to the Lehman Brothers  Municipal Bond Index, an
unmanaged  index of a broad range of investment  grade municipal bonds that is a
measure of the  performance of the general  municipal bond market.  However,  it
must be remembered that the index  performance  does not consider the effects of
transaction  costs  and that  the  Fund's  investments  are not  limited  to the
securities in the index.

Fees and Expenses of the Fund

The Fund pays a variety of  expenses  directly  for  management  of its  assets,
administration,  distribution of its shares and other  services.  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
the fees and  expenses  you may pay if you buy and hold shares of the Fund.  The
numbers  below are based on the Fund's  expenses  during  the fiscal  year ended
September 30, 1998.

Expenses may vary in future years. "Other expenses" include transfer agent fees,
custodial fees, and accounting and legal expenses the Fund pays.

Examples.  These examples are intended to help you compare the cost of investing
in the Fund with the cost of  investing  in other  mutual  funds.  The  examples
assume  that you  invest  $10,000  in a class of shares of the Fund for the time
periods indicated, and reinvest your dividends and distributions.

      The first example assumes that you redeem all of your shares at the end of
those periods.  The second example  assumes you keep your shares.  Both examples
also assume that your  investment has a 5% return each year and that the class's
operating  expenses  remain the same.  Your actual  costs may be higher or lower
because expenses will vary over time.  Based on these  assumptions your expenses
would be as follows:

  -----------------------------------------------------------------------------
  If shares are redeemed:       1 year      3 years     5 years    10 years1
  -----------------------------------------------------------------------------
  -----------------------------------------------------------------------------

  Class C Shares                $267        $517        $   892    $1,944

  -----------------------------------------------------------------------------
  Class C Shares                $167        $517        $892       $1,944
  -----------------------------------------------------------------------------

In the first example,  expenses include the initial sales charge for Class A and
the applicable  Class B or Class C contingent  deferred  sales  charges.  In the
second example,  the Class A expenses include the sales charge,  but Class B and
Class C expenses do not include contingent deferred sales charges.

1. Class B expense for years 7 through 10 are based on Class A  expenses,  since
Class B shares automatically convert to Class A after 6 years.

About the Fund's Investments

The Fund's Principal Investment Policies. The allocation of the Fund's portfolio
among the different  types of investments the Fund is permitted to buy will vary
over time based on the Manager's  evaluation  of economic and market  condition.
The Fund's  portfolio  might not always  include all of the  different  types of
investments  described below. The Statement of Additional  Information  contains
more detailed information about the Fund's investment policies and risks.

      |X| What  Municipal  Securities  Does the Fund  Invest  In?  The Fund buys
municipal  bonds  and  notes,  tax-exempt  commercial  paper,   certificates  of
participation  in municipal  leases and other debt  obligations.  These are debt
obligations  issued by the governments of states,  their political  subdivisions
(such as cities, towns and counties),  or the District of Columbia,  or by their
agencies, instrumentalities and authorities.

      The Fund can also buy securities issued by any commonwealths,  territories
or   possessions   of  the  United  States,   or  their   respective   agencies,
instrumentalities  or  authorities,  if the interest paid on the security is not
subject to Federal  individual income tax (in the opinion of bond counsel to the
issuer  at the  time  the  security  is  issued).  All of  these  types  of debt
obligations are referred to as "municipal securities" in this Prospectus.

      Municipal  securities are issued to raise money for a variety of public or
private  purposes,  including  financing  state or local  governments,  specific
projects or public facilities.  The Fund can invest in municipal securities that
are "general  obligations,"  secured by the  issuer's  pledge of its full faith,
credit and taxing power for the payment of principal and interest.

      The Fund can also buy  "revenue  obligations,"  whose  interest is payable
only  from  the  revenues  derived  from  a  particular  facility  or  class  of
facilities,  or a specific  excise tax or other  revenue  source.  Some of these
revenue  obligations are private  activity bonds that pay interest that may be a
tax preference item for investors subject to alternative minimum tax.

      |X| Ratings of Municipal  Securities the Fund Buys.  Most of the municipal
securities  the Fund buys are  "investment  grade" at the time of purchase.  The
Fund limits its investments in municipal securities that at the time of purchase
are not "investment-grade" to not more than 10% of its total assets. "Investment
grade"  securities are those rated within the four highest rating  categories of
Moody's,  Standard  &  Poor's,  Fitch or Duff &  Phelps  or  another  nationally
recognized  rating  organization,  or (if  unrated)  judged by the Manager to be
comparable  to securities  rated as  investment  grade.  Rating  categories  are
described in Appendix A to the Statement of Additional Information.

      The  Manager  relies  to some  extent  on  credit  ratings  by  nationally
recognized rating agencies in evaluating the credit risk of securities  selected
for the Fund's portfolio. It also uses its own research and analysis to evaluate
risks. Many factors affect an issuer's ability to make timely payments,  and the
credit risks of a particular security might change over time. A reduction in the
rating of a  security  after  its  purchase  by the Fund will not  automatically
require the Fund to dispose of that security. However, the Manager will evaluate
those securities to determine whether to keep them in the Fund's portfolio.

        |_|  Special  Credit  Risks  of  Lower-Grade   Securities.   Lower-grade
municipal   securities   usually  offer  higher  yields  than  investment  grade
securities but they are subject to greater market fluctuations and risks of loss
of income and principal than investment grade municipal  securities.  Securities
that are (or that have fallen) below  investment  grade have a greater risk that
the issuers of those securities might not meet their debt obligations.  However,
limiting its investments in  non-investment  grade  municipal  securities to not
more than 10% of its  assets,  helps the Fund reduce the effect of some of these
risks on its share price and income.

      |X|  Insured  Municipal  Securities.  Within  the  category  of  "insured"
municipal  securities  the  Fund  buys are (1)  those  securities  that  have an
insurance  policy  covering  the payment of all  installments  of  interest  and
repayment  of  principal  and (2)  "pre-refunded"  municipal  securities.  While
insurance  reduces  the  effects of risks of  default,  insurance  on  municipal
securities  the Fund buys does not guarantee or insure the market value of those
securities or the Fund's share prices.

      If an issuer defaults on an insured municipal security, the payment of the
claim under the insurance  policy  depends on the  claims-paying  ability of the
insurance company. There is a more detailed discussion of insurance on municipal
securities,  including  information about the costs,  limitations and risks that
apply to these policies, in the Statement of Additional Information.

      Insured municipal securities the Fund buys are covered by insurance in one
of several ways:

o        The Fund might buy (at its expense) a portfolio insurance policy issued
         by Financial Guaranty  Insurance Company,  which covers the security as
         long as the Fund  owns it. If the Fund  buys an  insurance  policy on a
         security,  the cost of that policy  increase  the Fund's  expenses  and
         reduces its yield.
o     The Fund might buy (at its expense) a secondary  market insurance policy
         from  Financial  Guaranty to cover payments of interest and principal
         for the remaining term of the security,  whether or not the Fund owns
         the  security.  The Fund would buy this type of  insurance  to enable
         the Fund to sell the security to a third party as the  equivalent  of
         an  "AAA"-rated  security  at a  higher  market  price  than  if  the
         security  were  sold  without  the  insurance.  It  might  replace  a
         portfolio insurance policy previously obtained.
o        Some municipal  securities are covered by an insurance  policy obtained
         by the issuer or its  underwriter  at the time the  security is issued.
         This insurance,  paid for by the issuer or its underwriter,  covers the
         interest and principal payments as long as the security is outstanding.
         The Fund limits  these  purchases  to  securities  insured by insurance
         companies  having an "AAA" or comparable  credit rating at the time the
         Fund buys them.

      In a  "pre-refunding"  the issuer of a municipal bond floats a second bond
to raise cash to pay off the first bond at its call date or dates.  The proceeds
of the second bond are invested in U.S.  Treasury  securities that mature on the
call date as security for the payment.  Because of the  collateral  arrangement,
these  bonds  typically  are rated in the  highest  rating  category of national
rating  organizations  and are  considered  by the Fund to have  the  equivalent
credit  protection  of  insured  securities.   However,  these  securities  also
typically offer a lower interest rate than the rate prevailing in the market for
comparable issues.

      |X| Municipal Lease  Obligations.  Municipal leases are one method used by
state  and  local  government  authorities  to  obtain  funds to  acquire  land,
equipment or facilities.  The Fund may invest in certificates  of  participation
that represent a  proportionate  interest in payments made under municipal lease
obligations.  If the government  stops making  payments or transfers its payment
obligations  to a private  entity,  the  obligation  could  lose value or become
taxable.  Some of these  obligations might not have an active trading market and
would be subject to the Fund's limits on "illiquid" securities described below.

      |X| Can the Fund's  Investment  Objective and Policies Change?  The Fund's
Board of  Trustees  can  change  non-fundamental  policies  without  shareholder
approval,  although  significant changes will be described in amendments to this
Prospectus.  Fundamental  policies are those that cannot be changed  without the
approval  of a majority  of the Fund's  outstanding  voting  shares.  The Fund's
investment  objective is a  fundamental  policy.  The  Statement  of  Additional
Information  lists investment  restrictions  that are fundamental  policies.  An
investment policy is not fundamental  unless this Prospectus or the Statement of
Additional Information says that it is.

Other Investment  Strategies.  To seek its objective,  the Fund can also use the
investment  techniques and  strategies  described  below.  The Manager might not
always use all of the different  types of techniques and  investments  described
below. These techniques involve certain risks although some of them are designed
to help reduce investment or market risks.

      |X|  Floating  Rate/Variable  Rate  Obligations.  Some  of  the  municipal
securities  the Fund can  purchase  have  variable or floating  interest  rates.
Variable rates are adjustable 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.  These  obligations  may be secured by bank letters of
credit or other credit support arrangements.

        |_| Inverse Floaters Have Special Risks.  Certain types of variable rate
bonds known as "inverse  floaters" pay interest at rates that vary 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.  As interest rates rise, inverse floaters produce
less  current  income,  and their  market  value can  become  volatile.  Inverse
floaters  are a type of  "derivative  security."  Some  have a "cap," so that 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 anticipates that
it will invest no more than 10% of its total assets in inverse floaters.

      |X|  Other  Derivatives.  The  Fund  can also  invest  in other  municipal
derivative  securities  that pay  interest  that  depends on changes in price or
value of an index or  another  investment.  Examples  of these  derivatives  are
interest rate swaps, and futures based on municipal bond indices.

      |X|  "When-Issued"  and  "Delayed-Delivery"  Transactions.  The  Fund  can
purchase municipal  securities on a "when-issued" basis and can purchase or sell
such 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.  The Fund  does  not  intend  to make  such
purchases for speculative  purposes.  During the period between the purchase and
settlement,  no payment is made for the security and no interest  accrues to the
buyer from the  investment.  There is a risk of loss to the Fund if the value of
the security declines prior to the settlement date.

      |X|  Puts  and  Stand-By  Commitments.  The  Fund  can  acquire  "stand-by
commitments" or "puts" with respect to municipal  securities.  These investments
give the Fund the right to sell the  securities  at a set price on demand to the
issuing broker-dealer or bank. However,  securities having this feature may have
a lower interest rate. The Fund will acquire stand-by commitments or puts solely
to enhance portfolio liquidity.

      |X| Illiquid and Restricted Securities.  Under the policies and procedures
established  by the  Fund's  Board  of  Trustees,  the  Manager  determines  the
liquidity 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 can increase that limit to 15%). Certain  restricted  securities that
are eligible for resale to qualified institutional purchasers may not be subject
to that limit.  The Manager  monitors  holdings  of  illiquid  securities  on an
ongoing  basis to determine  whether to sell any  holdings to maintain  adequate
liquidity.

      |X|  Hedging.  The Fund can  purchase  and sell  certain  kinds of futures
contracts,  put and call  options,  and  options  on futures  and  broadly-based
municipal bond indices,  or enter into interest rate swap agreements.  These are
all  referred  to as  "hedging  instruments."  The  Fund  does  not use  hedging
instruments  for  speculative  purposes,  and has limits on the use of them. The
Fund  does  not use  hedging  instruments  to a  substantial  degree  and is not
required to use them in seeking its goal.

      The Fund could buy and sell  options and futures for a number of purposes.
It might do so to try to manage its exposure to the possibility  that the prices
of its  portfolio  securities  may  decline,  or to  establish a position in the
securities   market  as  a  temporary   substitute  for  purchasing   individual
securities.  It might do so to try to manage its  exposure to changing  interest
rates.

      If the  Manager  used a hedging  instrument  at the  wrong  time or judged
market conditions incorrectly,  the strategy could 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,  interest  rate swaps are subject to credit risks and
also to interest  rate risks.  The Fund could be obligated to pay more under its
swap  agreements  than it  receives  under them,  as a result of  interest  rate
changes. The Fund will not enter into swaps with respect to more than 25% of its
total assets.

Temporary  Defensive  Investments.  The Fund can  invest up to 100% of its total
assets in temporary  defensive  investments from time to time. This could happen
during  periods of volatile or adverse market  conditions.  Generally the Fund's
defensive Investments would be short-term municipal securities but could be U.S.
government   securities  or  highly-rated   corporate  debt  securities.   These
investments are not insured.  The income from some of those temporary  defensive
investments might not be tax-exempt, and therefore when making those investments
the Fund might not achieve its objective.

      The Fund can also hold these types of investments  pending the investments
for cash management  purposes under normal market  conditions,  of proceeds from
the  sale  of Fund  shares  or  portfolio  securities,  or to  meet  anticipated
redemptions of Fund shares.

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

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

How the Fund is Managed

The  Manager.  The  Fund's  investment  Manager,   OppenheimerFunds,   Inc.,  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  Fund's  Board of  Trustees,  under an  Investment  Advisory
Agreement that states the Manager's  responsibilities.  The Agreement  lists the
fees the Fund pays 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 $95 billion as of December 31, 1998,
and with more than 4 million shareholder accounts. The Manager is located at Two
World Trade Center, 34th Floor, New York, New York 10048-0203.

     |X|  Portfolio  Manager.  The  portfolio  manager  of  the  Fund  is  Caryn
Halbrecht,  a Vice  President of the Fund and of the  Manager.  She has been the
person  principally  responsible  for the  day-to-day  management  of the Fund's
portfolio  since October 18, 1993.  Ms.  Halbrecht also serves as an officer and
portfolio manager for other Oppenheimer funds.

      |X| Advisory Fees. Under the Investment Advisory Agreement,  the Fund pays
the Manager an  advisory  fee at an annual  rate which  declines  on  additional
assets as the Fund grows: 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  average  annual  net  assets in excess of $500  million.  The  Fund's
management fee for its last fiscal year ended  September 30, 1998, was 0.440% of
average annual net assets for each class of shares.

About Your Account
- ------------------------------------------------------------------------------

How to Buy Shares

How Are Shares Purchased? You can buy shares several ways -- through any dealer,
broker or  financial  institution  that has a sales  agreement  with the  Fund's
Distributor,  or directly through the Distributor,  or automatically  through an
Asset  Builder  Plan  under  the   OppenheimerFunds   AccountLink  service.  The
Distributor  may  appoint  certain  servicing  agents  to accept  purchase  (and
redemption)  orders.  The Distributor,  in its sole  discretion,  may reject any
purchase order for the Fund's shares.

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

      |X|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,  we recommend  that you discuss your  investment
with a financial  advisor before you make a purchase to be sure that the Fund is
appropriate for you.

      |X|Buying  Shares by Federal  Funds  Wire.  Shares  purchased  through the
Distributor  may be paid for by Federal  Funds wire.  The minimum  investment is
$2,500.  Before  sending  a wire,  call the  Distributor's  Wire  Department  at
1-800-525-7048  to notify the  Distributor of the wire,  and to receive  further
instructions.

      |X|Buying Shares Through OppenheimerFunds  AccountLink.  With AccountLink,
shares  are  purchased  for  your  account  on  the  regular  business  day  the
Distributor is instructed by you to initiate the Automated  Clearing House (ACH)
transfer to buy the shares.  You can provide those  instructions  automatically,
under an Asset Builder Plan, described below, or by telephone instructions using
OppenheimerFunds PhoneLink, also described below. Please refer to "AccountLink,"
below for more details.

      |X|Buying  Shares Through 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 Asset  Builder  Application  and the
Statement of Additional Information.

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.  Subsequent  purchases of at least $25 can be made by telephone  through
AccountLink.

      |_|The  minimum  investment  requirement  does not  apply  to  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 reinvesting  distributions  from unit investment trusts that
have made arrangements with the Distributor.

At What Price Are Shares Sold?  Shares are sold at their offering price (the net
asset value per share plus any initial sales charge that applies).  The offering
price that applies to a purchase  order is based on the next  calculation of the
net asset  value per share  that is made  after  the  Distributor  receives  the
purchase order at its offices in Denver,  Colorado, or after any agent appointed
by the Distributor receives the order and sends it to the Distributor.

      |_|The  net asset  value of each class of shares is  determined  as of the
close of The New York  Stock  Exchange,  on each  day the  Exchange  is open for
trading  (referred  to in this  Prospectus  as a "regular  business  day").  The
Exchange  normally  closes at 4:00 P.M., New York time, but may close earlier on
some days. (All references to time in this Prospectus mean "New York time").

      The net asset value per share is  determined  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. To determine net asset value, the Fund's Board of Trustees
has established  procedures to value the Fund's securities,  in general based on
market value.  The Board has adopted  special  procedures  for valuing  illiquid
securities and obligations for which market values cannot be readily obtained.

      |_|To receive the offering  price for a particular  day, in most cases the
Distributor or its  designated  agent must receive your order by the time of day
The New York Stock Exchange  closes that day. If your order is received on a day
when the  Exchange is closed or after it has closed,  the order will receive the
next offering price that is determined after your order is received.

      |_|If you buy shares through a dealer,  your dealer must receive the order
by the close of The New York Stock  Exchange and transmit it to the  Distributor
so that it is received before the  Distributor's  close of business on a regular
business  day  (normally  5:00  P.M.) to  receive  that  day's  offering  price.
Otherwise, the order will receive the next offering price that is determined.

- ------------------------------------------------------------------------------
What Classes of Shares Does the Fund Offer?  The Fund offers  investors  three
different  classes  of  shares.  The  different  classes  of shares  represent
investments in the same  portfolio of securities,  but the classes are subject
to different  expenses and will likely have different  share prices.  When you
buy  shares,  be sure to  specify  the class of  shares.  If you do not choose a
class, your investment will be made in Class A shares.
- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------

- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------
      |X|   Class A  Shares.  If you buy Class A  shares,  you pay an  initial
sales  charge  (on  investments  up to $1  million).  The amount of that sales
charge will vary depending on the amount you invest.  The sales charge rates are
listed in "How Can I Buy Class A Shares?" below.
- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------

- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------
      |X|   Class B  Shares.  If you  buy  Class B  shares,  you pay no  sales
charge at the time of purchase,  but you will pay an annual  asset-based sales
charge,  and if you sell your shares within six years of buying them, you will
normally pay a contingent  deferred  sales charge.  That  contingent  deferred
sales charge varies  depending on how long you own your shares,  as described in
"How Can I Buy Class B Shares?" below.
- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------

- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------
      |X|Class C Shares.  If you buy Class C shares,  you pay no sales  charge
at the time of purchase,  but you will pay an annual asset-based sales charge,
and 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 "How Can
I Buy Class C Shares?" below.
- ------------------------------------------------------------------------------

Which  Class of Shares  Should You  Choose?  Once you decide that the Fund is an
appropriate investment for you, the decision as to which class of shares is best
suited to your needs depends on a number of factors that you should discuss with
your financial advisor. Some 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.
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  discussion  below  is  not  intended  to be  investment  advice  or a
recommendation,  because each investor's financial considerations are different.
You should  review these factors with your  financial  advisor.  The  discussion
below  assumes  that  you will  purchase  only one  class of  shares,  and not a
combination of shares of different classes.

      |X|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,  compared to the effect over
time of higher class-based expenses on shares of Class B or Class C .

        |_| Investing  for the Short Term.  If you have a relatively  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.  That is  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 as 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.

      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.

        |_|  Investing  for the  Longer  Term.  If you are  investing  less than
$100,000 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
appropriate.

      Of course,  these  examples are based on  approximations  of the effect of
current sales charges and expenses projected over time, and do not detail all of
the  considerations  in  selecting a class of shares.  You should  analyze  your
options carefully with your financial advisor before making that choice.

      |X|Are There  Differences  in Account  Features  That Matter to You?  Some
account features (such as checkwriting) may not be available to Class B or Class
C shareholders.  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.  Therefore, you should carefully review how you
plan to use your  investment  account  before  deciding which class of shares to
buy.  Additionally,  the 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
charge  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.

      |X|How Does It Affect  Payments  to My Broker?  A  salesperson,  such as a
broker, may receive different  compensation for selling one class of shares than
for selling  another class. It is important to remember that Class B and Class C
contingent  deferred sales charges and  asset-based  sales charges have the same
purpose as the front-end sales charge on sales of Class A shares:  to compensate
the Distributor  for  commissions it pays to dealers and financial  institutions
for selling shares. The Distributor may pay additional 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.

Special Sales Charge  Arrangements  and Waivers.  Appendix C to the Statement of
Additional  Information  details the  conditions for the waiver of sales charges
that apply in certain  cases,  and the special  sales charge rates that apply to
purchases of shares of the Fund by certain groups, or under specified retirement
plan arrangements or in other special types of transactions.

How Can I Buy 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 other  cases,  reduced
sales  charges may be  available,  as  described  below or in the  Statement  of
Additional Information.  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  or allocated to
your dealer as  commission.  The  Distributor  reserves the right to reallow the
entire  commission to dealers.  The current  sales charge rates and  commissions
paid to dealers and brokers are as follows:

  ----------------------------------------------------------------------------
                            ----------------- Front-End Sales   Commission as

      |X| 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  in an amount equal to 1.0% of purchases of $1 million or more other
than by retirement accounts. That commission will be paid only on purchases that
were not previously subject to a front-end sales charge and dealer commission.

      If you  redeem  any of those  shares  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.  That  sales  charge  will be equal to 1.0% of the  lesser  of (1) the
aggregate  net asset  value of the  redeemed  shares  at the time of  redemption
(excluding  shares  purchased  by  reinvestment  of  dividends  or capital  gain
distributions)  or (2) 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
purchases of Class A shares of all Oppenheimer  funds you made that were subject
to the Class A contingent deferred sales charge.

      In determining  whether a contingent deferred sales charge is payable when
shares are  redeemed,  the Fund will first redeem shares that are not subject to
the sales charge,  including  shares  purchased by reinvestment of dividends and
capital gains.  Then the Fund will redeem other shares in the order in which you
purchased  them.  The  Class A  contingent  deferred  sales  charge is waived in
certain   cases   described  in  Appendix  C  to  the  Statement  of  Additional
Information.

      The Class A contingent  deferred  sales charge is not charged on exchanges
of shares under the Fund's exchange privilege (described below). However, if the
shares acquired by exchange are redeemed within 18 calendar months of the end of
the calendar month in which the exchanged shares were originally purchased, then
the sales charge will apply.

How Can I Reduce Sales Charges for Class A Share Purchases?  You may be eligible
to buy Class A shares at reduced  sales charge rates under the Fund's  "Right of
Accumulation" or a Letter of Intent,  as described in "Reduced Sales Charges" in
the Statement of Additional Information.

      |X| Waivers of Class A Sales  Charges.  The Class A initial and contingent
deferred  sales  charges  are not  imposed  in the  circumstances  described  in
Appendix C to 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 when  purchasing  shares  whether any of the special  conditions
apply.

How Can I Buy 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.  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.

      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 an increase in
      net asset value over the initial purchase price,

      |_|   shares  purchased  by the  reinvestment  of  dividends  or capital
      gains distributions, or

      |_| shares redeemed in the special  circumstances  described in Appendix C
      to the Statement of Additional Information.

      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 6 years, and

      (3) shares held the longest during the 6-year period.

      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 on
  Years Since Beginning of Month in     Redemptions in That Year
  Which Purchase Order was Accepted     (As % of Amount Subject to Charge)
  ----------------------------------------------------------------------------
  ----------------------------------------------------------------------------
  0 - 1                                 5.0%
  ----------------------------------------------------------------------------
  ----------------------------------------------------------------------------
  1 - 2                                 4.0%
  ----------------------------------------------------------------------------
  ----------------------------------------------------------------------------
  2 - 3                                 3.0%
  ----------------------------------------------------------------------------
  ----------------------------------------------------------------------------
  3 - 4                                 3.0%
  ----------------------------------------------------------------------------
  ----------------------------------------------------------------------------
  4 - 5                                 2.0%
  ----------------------------------------------------------------------------
  ----------------------------------------------------------------------------
  5 - 6                                 1.0%
  ----------------------------------------------------------------------------
  ----------------------------------------------------------------------------
  6 and following                       None
  ----------------------------------------------------------------------------

In the table, a "year" is a 12-month period.  In applying the sales charge,  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.  Class B shares automatically
convert to Class A shares 72 months after you  purchase  them.  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 the Statement of Additional Information.

How Can I Buy 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.  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.

      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
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,

o     shares  purchased by the  reinvestment  of  dividends  or capital  gains
         distributions, or
o        shares redeemed in the special circumstances described in Appendix C to
         the Statement of Additional Information.

      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

(4) shares held the longest during the 12-month period.

Distribution and Service (12b-1) Plans.

      |X| Service  Plan for Class A Shares.  The Fund has adopted a Service Plan
for Class A shares.  It reimburses  the  Distributor  for a portion of its costs
incurred  for  services   provided  to  accounts   that  hold  Class  A  shares.
Reimbursement  is made quarterly at an annual rate of up to 0.25% of the average
annual  net  assets of Class A shares of the Fund.  The rate is 0.15% of average
annual  net  assets  represented  by  shares  acquired  before  that  date.  The
Distributor currently uses all of those fees to pay dealers,  brokers, banks and
other  financial  institutions  quarterly  for  providing  personal  service and
maintenance of accounts of their customers that hold Class A shares.

      |X|  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 its services and costs in 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.

      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.  Because
these fees are paid out of the Fund's  assets on an  on-going  basis,  over time
these fees will increase the cost of your  investment and may cost you more than
other types of sales charges.

      The Distributor uses the service fees to compensate  dealers for providing
personal  services  for  accounts  that  hold  Class B or  Class C  shares.  The
Distributor pays the 0.25% service fees to dealers in advance for the first year
after the shares were sold by the dealer.  After the shares have been held for a
year, the Distributor pays the service fees to dealers on a quarterly basis.

      The Distributor  currently pays sales  commission 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  therefore
4.00% of the purchase  price.  The  Distributor  retains the Class B asset-based
sales charge.

      The Distributor  currently pays sales commissions of 0.75% of the purchase
price of Class C 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 sale of Class C shares  is  therefore
1.00% of the purchase price. The Distributor  pays 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.

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

Are There Limits on Amounts Redeemed by Telephone?

      |X| 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.

      |X| Telephone Redemptions Through AccountLink.  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.

Checkwriting  Against Your Account.  To write checks  against your Fund account,
request  that  privilege on your  account  Application,  or contact the Transfer
Agent for signature cards.  They 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 other account.

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

      |_| 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.

      |_|   Checks must be written for at least $100.

      |_|   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.

      |_| 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.

      |_| Don't use your checks if you changed your Fund account  number,  until
you receive new checks.

Can I Sell Shares Through My 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.  If your shares are held in the
name of your dealer, you must redeem them through your dealer.

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:

      |_|         Shares of the fund  selected for exchange  must be available
for sale in your state of residence.

      |_| The  prospectuses  of this Fund and the fund whose  shares you want to
buy must offer the exchange privilege.

      |_| 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.

      |_|         You must  meet the  minimum  purchase  requirements  for the
fund you purchase by exchange.

      |_|         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.  In some
cases, sales charges may be imposed on exchange transactions.  For tax purposes,
exchanges  of  shares  involve  a sale 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.  Please refer to "How to Exchange  Shares" in the  Statement of Additional
Information for more details.

How Do I Submit  Exchange  Requests?  Exchanges may be requested in writing or
by telephone:

      |X|         Written  Exchange  Requests.   Submit  an   OppenheimerFunds
Exchange  Request  form,  signed by all owners of the account.  Send it to the
Transfer  Agent at the  address on the Back  Cover.  Exchanges  of shares held
under certificates  cannot be processed unless the Transfer Agent receives the
certificates with the request.

      |X| Telephone Exchange  Requests.  Telephone exchange requests may be made
either by  calling  a  service  representative  at  1-800-552-8457,  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.

Are There  Limitations on Exchanges?  There are certain exchange  policies you
should be aware of:

      |_| 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 conforms to the policies
described above. It must be received 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
exchange.  For example, the receipt of multiple exchange requests from a "market
timer"  might  require the Fund to sell  securities  at a  disadvantageous  time
and/or price.

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

      |_| 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.

      |_| 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

More  information  about the fund's policies and procedures for buying,  selling
and exchanging shares is contained in the Statement of Additional Information.

      |X| 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.

      |X|  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 the
Transfer Agent receives cancellation instructions from an owner of the account.

      |X| 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.  The Transfer Agent and the Fund will
not be liable for  losses or  expenses  arising  out of  telephone  instructions
reasonably believed to be genuine.

      |X| 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.

      |X| 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.

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

      |X|  Payment  for  redeemed  shares  ordinarily  is  made in  cash.  It is
forwarded by check or through AccountLink (as elected by the shareholder) within
seven days after the Transfer Agent receives  redemption  instructions in proper
form.  However,  under unusual  circumstances  determined by the  Securities and
Exchange  Commission,   payment  may  be  delayed  or  suspended.  For  accounts
registered  in the name of a  broker-dealer,  payment will normally be forwarded
within three business days after redemption.

      |X| 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 or  certified  check,  or arrange  with your bank to provide
telephone or written  assurance to the Transfer Agent that your purchase payment
has cleared.

      |X|  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. In some cases involuntary redemptions may be
made to repay the Distributor for losses from the cancellation of share purchase
orders.

      |X| Shares may be "redeemed in kind" under unusual  circumstances (such as
a lack of liquidity in the Fund's  portfolio  to meet  redemptions).  This means
that the  redemption  proceeds  will be paid  with  securities  from the  Fund's
portfolio.

      |X|  "Backup  Withholding"  of Federal  income tax may be applied  against
taxable dividends,  distributions and redemption proceeds (including  exchanges)
if you fail to furnish  the Fund your  correct,  certified  Social  Security  or
Employer  Identification  Number  when  you  sign  your  application,  or if you
under-report your income to the Internal Revenue Service.

      |X| 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 and Tax Information

Dividends.  The Fund intends to declare  dividends  separately for each class of
shares from net  tax-exempt  income  and/or net  investment  income each regular
business  day and to pay  those  dividends  to  shareholders  monthly  on a date
selected by the Board of Trustees.  Daily dividends will not be declared or paid
on newly-purchased shares until Federal Funds are available to the Fund from the
purchase payment for such shares.

      The Fund attempts to pay dividends on Class A shares at a constant  level.
There is no  assurance  that it will be able to do so. The Board of Trustees may
change  the  targeted  dividend  level at any  time,  without  prior  notice  to
shareholders.  Dividends and distributions paid on Class A shares will generally
be  higher  than for  Class B and Class C shares,  which  normally  have  higher
expenses than Class A. The Fund cannot  guarantee that it will pay any dividends
or distributions.

Capital  Gains.  Although the Fund does not seek capital  gains,  it may realize
capital  gains  on the sale of  portfolio  securities.  If it does,  it may make
distributions  out of any net short-term or long-term  capital gains in December
of each year.  The Fund may make  supplemental  distributions  of dividends  and
capital gains following the end of its fiscal year. Long-term capital gains will
be separately identified in the tax information the Fund sends you after the end
of the calendar year.

What Choices Do I Have for Receiving Distributions?  When you open your account,
specify  on  your  application  how you  want  to  receive  your  dividends  and
distributions. You have four options:

      |X|         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.

      |X|  Reinvest  Long-Term  Capital  Gains  Only.  You can elect to reinvest
long-term capital gains  distributions in the Fund while receiving  dividends by
check or having them sent to your bank account through AccountLink.

      |X|         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 through AccountLink.

      |X|         Reinvest  Your  Distributions  in  Another  OppenheimerFunds
Account.  You can  reinvest all  distributions  in the same class of shares of
another OppenheimerFunds account you have established.

Taxes. Dividends paid from net investment income earned by the Fund on municipal
securities will be excludable from gross income for Federal income tax purposes.
A portion of a dividend that is derived from  interest paid on certain  "private
activity  bonds"  may be an item of tax  preference  if you are  subject  to the
alternative minimum tax. If the Fund earns interest on taxable investments,  any
dividends  derived  from those  earnings  will be taxable as ordinary  income to
shareholders.

      Dividends and capital gains distributions may be subject to state or local
taxes.  Long-term  capital  gains are taxable as  long-term  capital  gains when
distributed  to  shareholders.  It does not  matter  how long you have held your
shares.  Dividends paid from  short-term  capital gains and  non-tax-exempt  net
investment  income are taxable as ordinary  income.  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.

      |X|  Remember,  There May be Taxes on  Transactions.  Even though the Fund
seeks to distribute  tax-exempt  income 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.

      |X|         Returns  of   Capital   Can   Occur.   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.

      This  information  is only a summary of certain  federal  tax  information
about your investment. You should consult with your tax adviser about the effect
of an investment in the Fund on your particular tax situation.

Financial Highlights

The Financial  Highlights  Table is presented to help you  understand the Fund's
financial  performance for the past 5 fiscal years. Certain information reflects
financial  results  for a single  Fund  share.  The total  returns  in the table
represent the rate that an investor would have earned [or lost] on an investment
in the Fund (assuming  reinvestment  of all dividends and  distributions).  This
information  has been audited by Deloitte & Touche LLP,  the Fund's  independent
auditors, whose report, along with the Fund's financial statements,  is included
in the Statement of Additional Information, which is available on request.

ABOUT THE FUND
- ------------------------------------------------------------------------------

Additional Information About the Fund's Investment Policies and Risks

The investment  objective and the principal  investment policies of the Fund are
described in the Prospectus.  This Statement of Additional  Information contains
supplemental  information  about those policies and the types of securities that
the Fund's investment Manager, OppenheimerFunds,  Inc., can select for the Fund.
Additional  explanations are also provided about the strategies the Fund may use
to try to achieve its objective.

The Fund's Investment Policies.  The composition of the Fund's portfolio and the
techniques and strategies that the Fund's Manager may use in selecting portfolio
securities  will  vary over  time.  The Fund is not  required  to use all of the
investment techniques and strategies described below at all times in seeking its
goal. It may use some of the special  investment  techniques  and  strategies at
some times or not at all. The Fund does not make  investments with the objective
of seeking  capital  growth.  However,  the values of the securities held by the
Fund may be affected  by changes in general  interest  rates and other  factors,
prior to their  maturity.  Because the current  values of debt  securities  vary
inversely with changes in prevailing  interest rates, if interest rates increase
after a security  is  purchased,  that  security  will  normally  fall in value.
Conversely,  should  interest  rates  decrease  after a security  is  purchased,
normally its value will rise.

      However, those fluctuations in value will not generally result in realized
gains or losses to the Fund  unless  the Fund  sells the  security  prior to the
security's  maturity.  A debt  security  held to maturity is  redeemable  by its
issuer at full principal value plus accrued interest.  The Fund does not usually
intend to  dispose  of  securities  prior to their  maturity,  but may do so for
liquidity purposes,  or because of other factors affecting the issuer that cause
the  Manager  to sell the  particular  security.  In that  case,  the Fund could
realize a capital gain or loss on the sale.

      There are variations in the credit quality of municipal  securities,  both
within a particular rating  classification  and between  classifications.  These
variations depend on numerous factors. The yields of municipal securities depend
on a number of factors, including general conditions in the municipal securities
market,  the size of a particular  offering,  the maturity of the obligation and
rating (if any) of the issue.  These  factors are  discussed  in greater  detail
below.

      |X| Portfolio  Turnover.  A change in the securities held by the Fund from
buying and selling  investments  is known as  "portfolio  turnover."  Short-term
trading  increases the rate of portfolio  turnover and could increase the Fund's
transaction  costs.  However,  the Fund ordinarily incurs little or no brokerage
expense because most of the Fund's  portfolio  transactions are principal trades
that do not require payment of brokerage commissions.

      The Fund  ordinarily  does not trade  securities to achieve capital gains,
because they would not be tax-exempt  income. To a limited degree,  the Fund may
engage in short-term  trading to attempt to take advantage of short-term  market
variations.  It may also do so to dispose of a portfolio  security  prior to its
maturity.  That might be done if, on the basis of a revised credit evaluation of
the issuer or other  considerations,  the Manager  believes such  disposition is
advisable or the Fund needs to generate cash to satisfy  requests to redeem Fund
shares.  In those  cases,  the Fund may  realize a  capital  gain or loss on its
investments.  The Fund's annual portfolio turnover rate normally is not expected
to exceed 100%.

Municipal  Securities.  The types of municipal  securities in which the Fund may
invest are  described in the  Prospectus  under "About the Fund's  Investments."
Municipal  securities  are  generally  classified as general  obligation  bonds,
revenue bonds and notes.  A discussion of the general  characteristics  of these
principal types of municipal securities follows below.

      |X| Municipal  Bonds. We have  classified  municipal  securities  having a
maturity (when-issued) of more than one year as "municipal bonds." The principal
classifications  of  long-term  municipal  bonds are  "general  obligation"  and
"revenue"  (including  "industrial  development")  bonds.  They may have  fixed,
variable or floating rates of interest, as described below.

      Some bonds may be  "callable,"  allowing  the issuer to redeem them before
their maturity date. To protect  bondholders,  callable bonds may be issued with
provisions that prevent them from being called for a period of time.  Typically,
that is 5 to 10 years from the issuance date.  When interest  rates decline,  if
the call protection on a bond has expired, it is more likely that the issuer may
call the bond.  If that occurs,  the Fund might have to reinvest the proceeds of
the called bond in bonds that pay a lower rate of return.

        |_|  General   Obligation  Bonds.  The  basic  security  behind  general
obligation  bonds is the issuer's pledge of its full faith and credit and taxing
power,  if any,  for the  repayment  of  principal  and the payment of interest.
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 rate of taxes that can be
levied  for the  payment  of debt  service  on these  bonds  may be  limited  or
unlimited. Additionally, there may be limits as to the rate or amount of special
assessments that can be levied to meet these obligations.

        |_|  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 tax or other
specific  revenue source.  Revenue bonds are issued to finance a wide variety of
capital  projects.  Examples  include  electric,  gas,  water and sewer systems;
highways,  bridges,  and  tunnels;  port and airport  facilities;  colleges  and
universities; and hospitals.

      Although  the  principal  security  for these types of bonds may vary from
bond to bond,  many  provide  additional  security in the form of a debt service
reserve fund that 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.

        |_|  Industrial  Development  Bonds.  Industrial  development  bonds are
considered  municipal  bonds if the interest paid is exempt from federal  income
tax.  They 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 may also be 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 financed by the bond as security
for those payments.

   
     |_| 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 certain types of municipal securities.  The Tax Reform
Act  generally  did not change  the tax  treatment  of bonds  issued in order to
finance  governmental  operations.  Thus,  interest on general  obligation bonds
issued by or on behalf of state or local governments,  the proceeds of which are
used to finance the operations of such governments,  continues to be tax-exempt.
However,   the  Tax  Reform  Act  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 is
taxable  under  the  revised  rules.  There  is  an  exception  for  "qualified"
tax-exempt private activity bonds, for example,  exempt facility bonds including
certain  industrial  development  bonds,  qualified  mortgage  bonds,  qualified
Section  501(c)(3) bonds, and qualified student loan bonds. 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.
    

      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.

      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.  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 Federal alternative minimum tax is designed to ensure that all persons
who receive  income pay some tax,  even if their  regular  tax is zero.  This is
accomplished in part by including in taxable income certain tax preference items
that are used to calculate  alternative  minimum taxable income.  The Tax Reform
Act  made  tax-exempt  interest  from  certain  private  activity  bonds  a  tax
preference item for purposes of the  alternative  minimum tax on individuals and
corporations.  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 the  proportionate  relationship  the interest the investment  company
receives on such bonds bears to all its exempt interest dividends.

      In addition,  corporate  taxpayers subject to the alternative  minimum tax
may,  under some  circumstances,  have to include  exempt-interest  dividends in
calculating  their  alternative  minimum  taxable  income.  That could  occur in
situations where the "adjusted current earnings" of the corporation  exceeds its
alternative minimum taxable income.

      To determine whether a municipal  security is treated as a taxable private
activity  bond,  it is subject to 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 the 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 private loan restriction,  the amount of
bond proceeds that 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 the
use of the bond-financed  facility. The Fund makes no independent  investigation
of the users of such bonds or their use of  proceeds  of the bonds.  If the Fund
should hold a bond that loses its tax-exempt status  retroactively,  there might
be  an  adjustment  to  the   tax-exempt   income   previously   distributed  to
shareholders.

      Additionally,  a private activity bond that 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 applies primarily to exempt
facility bonds,  including industrial  development bonds. The Fund may invest in
industrial  development bonds and other private activity bonds.  Therefore,  the
Fund may not be an appropriate  investment  for entities which are  "substantial
users" (or persons  related to "substantial  users") of such exempt  facilities.
Those entities and persons should consult their tax advisers  before  purchasing
shares of the Fund.

      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 individual or the
individual'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.

      |X| Municipal  Notes.  Municipal  securities  having a maturity  (when the
security  is  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.  Some of the types of municipal  notes the Fund can invest in are
described below.

        |_| Tax Anticipation  Notes. These 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 other business taxes, and
are payable from these specific future taxes.

        |_| Revenue   Anticipation   Notes.   These   are   notes   issued  in
expectation  of receipt of other  types of revenue,  such as Federal  revenues
available under Federal revenue-sharing programs.

        |_| Bond  Anticipation  Notes.  Bond  anticipation  notes are  issued to
provide  interim  financing  until  long-term  financing  can be  arranged.  The
long-term  bonds  that are  issued  typically  also  provide  the  money for the
repayment of the notes.

        |_|  Construction  Loan  Notes.   These  are  sold  to  provide  project
construction   financing  until  permanent  financing  can  be  secured.   After
successful  completion and acceptance of the project,  it may receive  permanent
financing through public agencies, such as the Federal Housing Administration.

     |X|   Tax Exempt Commercial  Paper.  This type of short-term  obligation
(usually  having a maturity  of 270 days or less) is issued by a  municipality
to meet current working capital needs.

      |X| Municipal Lease Obligations. The Fund's investments in municipal lease
obligations  may be through  certificates of  participation  that are offered to
investors by public  entities.  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.

      Some municipal lease securities may be deemed to be "illiquid" securities.
Their  purchase  by the Fund would be limited as  described  below in  "Illiquid
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 Board of Trustees.  Those guidelines  require
the Manager to evaluate:
          |_| the frequency of trades and price quotations for such securities;
          |_| the  number  of  dealers  or other  potential  buyers  willing  to
     purchase or sell such securities;
          |_| the availability of market-makers; and
          |_| the nature of the trades for such securities.

      Municipal  leases  have  special  risk   considerations.   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 that purpose on a yearly basis.  While the obligation
might be secured by the lease, it might be difficult to dispose of that property
in case of a default.

      Projects  financed with  certificates of  participation  generally are not
subject to state constitutional debt limitations or other statutory requirements
that may apply to other municipal  securities.  Payments by the public entity on
the obligation  underlying the certificates  are derived from available  revenue
sources.  That  revenue  might 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 a state
or any of its political subdivisions.

In addition to the risk of  "non-appropriation,"  municipal lease  securities do
not have as highly liquid a market as conventional  municipal  bonds.  Municipal
leases,  like  other  municipal  debt  obligations,  are  subject to the risk of
non-payment of interest or repayment of principal by the issuer.  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. A default in
payment of income would  result in a reduction  of income to the Fund.  It could
also result in a reduction in the value of the municipal lease and that, as well
as a default in  repayment of  principal,  could result in a decrease in the net
asset value of the Fund. While the Fund holds such securities,  the Manager will
also evaluate the  likelihood of a continuing  market for these  securities  and
their credit quality.

      |X| Ratings of Municipal Securities. Ratings by ratings organizations such
as Moody's Investors Service,  Standard & Poor's Ratings Service and Fitch IBCA,
Inc.  represent the respective rating agency's opinions of the credit quality of
the municipal  securities  they  undertake to rate.  However,  their ratings are
general  opinions and are not guarantees of quality.  Municipal  securities that
have the same maturity, coupon and rating may have different yields, while other
municipal  securities  that have the same  maturity  and  coupon  but  different
ratings may have the same yield.

      Subsequent to its purchase by the Fund, a municipal  security may cease to
be rated or its rating may be reduced below the minimum required for purchase by
the Fund. Neither event requires the Fund to sell the security,  but the Manager
will consider  such events in  determining  whether the Fund should  continue to
hold the  security.  To the extent that  ratings  given by  Moody's,  Standard &
Poor's, or Fitch change as a result of changes in those rating  organizations or
their  rating  systems,  the Fund will  attempt  to use  comparable  ratings  as
standards for investments in accordance with the Fund's investment policies.

      The  Fund  can buy  municipal  securities  that  are  "pre-refunded."  The
issuer's  obligation to repay the  principal  value of the security is generally
collateralized with U.S. government securities placed in an escrow account. This
causes the  pre-refunded  security to have essentially the same risks of default
as a AAA-rated security.

      The rating  definitions of Moody's,  Standard & Poor's,  Duff & Phelps and
Fitch for municipal  securities are contained in Appendix A to this Statement of
Additional  Information.  The Fund can purchase  securities  that are unrated by
nationally  recognized  rating  organizations,  the  Manager  will  make its own
assessment of the credit  quality of unrated  issues the Fund buys.  The Manager
will use  criteria  similar to those used by the rating  agencies,  and assign a
rating category to a security that is comparable to what the Manager  believes a
rating agency would assign to that security.  However, the Manager's rating does
not constitute a guarantee of the quality of a particular issue.

        |_| Special Risks of Lower-Grade Securities.  Lower grade securities may
have a higher yield than securities  rated in the higher rating  categories.  In
addition to having a greater risk of default than higher-grade securities, there
may be less of a market for these securities.  As a result they may be harder to
sell at an acceptable  price.  The  additional  risks mean that the Fund may not
receive the anticipated  level of income from these  securities,  and the Fund's
net  asset  value  may be  affected  by  declines  in the  value of  lower-grade
securities.  However,  because the added risk of lower quality  securities might
not be consistent with the Fund's policy of  preservation  of capital,  the Fund
limits its investments in lower quality securities.

      While  securities  rate "Baa" by Moody's or "BBB" by  Standard & Poor's or
Duff & Phelps are  investment  grade,  they may be subject to special  risks and
have some speculative characteristics.

      |X|  Insured  Municipal  Securities.  Not all of the  Fund's  holdings  of
municipal  securities  are  insured.  As noted  in the  Prospectus,  within  the
category of "insured"  municipal  securities,  the Fund includes  "pre-refunded"
municipal  securities,  because of the additional credit security offered by the
U.S. government securities that collateralize the issuer's obligation to pay its
debt.  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. This insurance substantially reduces
the risks to the Fund and its  shareholders  from  defaults  in the  payment  of
principal and interest on portfolio securities owned by the Fund.

      Insurance coverage can be in one of three methods:
      a mutual fund "Portfolio Insurance Policy" issued by Financial
         Guaranty Insurance Company,
      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 that security  typically will
not be  additionally  insured  under a  Portfolio  Insurance  Policy  issued  by
Financial Guaranty Insurance Company.  New Issue Insurance Policies or Secondary
Market Insurance  Policies may be issued by Financial Guaranty Insurance Company
or by other insurers.

      The insurance  policies  discussed above insure the scheduled  payments of
all principal and interest on the covered municipal securities as those payments
fall due. The  insurance  does not  guarantee  the market value of the municipal
securities  or the value of the shares of the Fund.  Except as described  below,
insurance of municipal  securities  the Fund buys 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 of the  security.  Payment of a claim  under an  insurance  policy
depends on the  claims-paying  ability of the  insurer  and by the Fund makes no
representations that any insurer will be able to meet its commitments.

        |_| New Issue Insurance  Policies.  A New Issue Insurance  Policy,  on a
municipal  security is obtained by the issuer or  underwriters of that security.
All premiums on the insurance for a security is paid in advance by the issuer or
underwriter.  Those policies are non-cancelable and continue in force so long as
the security is outstanding and the insurer remains in business. Since New Issue
Insurance  remains  in effect as long as the  security  insured by the policy is
outstanding,  the  insurance  may  have an  effect  on the  resale  value of the
security  by the Fund.  Therefore,  New Issue  Insurance  may be  considered  to
represent an element of market value for a security insured by that policy,  but
the exact  effect,  if any, of that  insurance  on the  security's  market value
cannot be estimated.  The Fund will acquire a municipal  security subject to New
Issue Insurance Policies only if the claims-paying  ability of the insurer under
the policy is rated "AAA" by S&P, or has a comparable rating from another rating
organization on the date the Fund buys the security.

        |_| Portfolio Insurance Policies.  A Portfolio Insurance Policy obtained
by the Fund from Financial  Guaranty Insurance Company will be effective only so
long as the Fund is in existence,  Financial  Guaranty  Insurance  Company is in
business,  and the municipal security covered by the policy continues to be held
by the Fund. If the Fund sells the insured municipal security or if the security
is called or  redeemed  prior to its stated  maturity  the  Portfolio  Insurance
Policy terminates on the security.

      A  Portfolio  Insurance  Policy  obtained  by the Fund is  non-cancellable
except for the Fund's  failure to pay the premium.  Nonpayment  of premiums on a
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 Insurance Company to take action against the
Fund to recover  premium  payments that are due. The premium rate for a security
covered by a Portfolio Insurance Policy is fixed for the life of the security at
the time the Fund buys it. 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 Insurance Company 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 then  determine  as promptly as possible  whether the Fund should sell that
security.

      In determining whether to insure a municipal security,  Financial Guaranty
Insurance Company applies its own standards,  which are not necessarily the same
as the criteria  used by the Manager when  selecting  securities  for the Fund's
portfolio. The decision whether to insure a security is made prior to the Fund's
purchase of that  security.  A contract to purchase a security is not covered by
the Portfolio Insurance Policy for that security although securities  underlying
such  contracts  are  covered by the  insurance  upon  physical  delivery of the
securities to the Fund or the Fund's  custodian  bank.  The Fund does not obtain
insurance on investments made for temporary liquidity and defensive purposes and
pending investment in longer term municipal securities.

      Premiums are paid from the Fund's assets,  and will  therefore  reduce the
Fund's  current  yield.  When the Fund  purchases a Secondary  Market  Insurance
Policy,  the single premium is added to the cost basis of the municipal security
and is not considered an item of expense for the Fund.

        |_| Secondary Market  Insurance.  The Fund might decide to purchase from
Financial  Guaranty Insurance Company a Secondary Market Insurance Policy on any
municipal  security can purchased by the Fund owns that is already  covered by a
Portfolio  Insurance Policy. The Fund obtain a Secondary Market Insurance Policy
on a security even if it is covered by a Portfolio  Insurance  Policy.  However,
the  coverage  (and  obligation  to pay monthly  premiums)  under the  Portfolio
Insurance  Policy with respect to that security would cease when the purchases a
Secondary Market Insurance Policy on that security.

      When  purchasing  a Secondary  Market  Insurance  Policy,  the Fund pays a
single  pre-determined  premium.  The Fund  thereby  obtains  insurance  against
non-payment  of scheduled  principal and interest for the remaining  term of the
security,  regardless  of whether  the Fund owns the  security.  That  insurance
coverage  will be  non-cancellable  and  will  continue  in force so long as the
insured security is outstanding.  Acquiring that type of policy enables 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. That rating is not automatic,
however,  and must  specifically  be  requested  from  Standard  & Poor's  for a
security.  This type of policy likely would be purchased if, the Manager, thinks
that the market  value or net proceeds of a sale of the insured  security  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  that rating,  including  the cost of the
insurance  single  premium,  would  inure  to the  Fund in  determining  its net
realized capital gain or loss the sale of the security.

      The Fund can purchase  insurance under a Secondary Market Insurance Policy
in lieu of a Portfolio Insurance Policy at any time, regardless of the effect on
the 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 Fund can purchase a Secondary  Market  Insurance  Policy on a
security that is currently in default as to payments by the issuer to enable the
Fund to sell the  security on an insured  basis rather than be obligated to hold
the  defaulted  security  in its  portfolio  in  order  to  continue  in force a
Portfolio Insurance Policy on that security.

   
     |_| Financial  Guaranty  Insurance  Company.  The  information  below about
Financial Guaranty Insurance Company is derived from publicly-available  sources
believed reliable by the Manager.  Financial Guaranty Insurance Company is a New
York stock insurance company, with principal offices at 115 Broadway,  New York,
New York, 10006. Financial Guaranty Insurance Company, 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.  Financial  Guaranty
Insurance  Company is a  subsidiary  of FGIC  Corporation,  a  Delaware  holding
company.  FGIC  Corporation  is a  wholly-owned  subsidiary of General  Electric
Capital  Corporation.  Neither FGIC  Corporation  nor General  Electric  Capital
Corporation  are obligated to pay the debts of or the claims  against  Financial
Guaranty Insurance Company.
    

      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,  Financial Guaranty  Insurance Company  provides insurance for
new issues and  secondary  market  issues of  municipal  bonds and notes and for
portions of those issues.  Financial  Guaranty  Insurance  Company also provides
credit enhancements for asset-backed securities and mortgage-backed securities.

      Financial  Guaranty  Insurance  Company 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 Insurance Company is also subject to regulation
by the State of New York Insurance Department.  That regulation is no guarantee
that  Financial  Guaranty  Insurance  Company  will be able  to  perform  on its
commitments  or contracts of insurance if a claim under them at some time in the
future.

   
     Under the provisions of a Portfolio  Insurance Policy,  Financial  Guaranty
Insurance Company  unconditionally and irrevocably agrees to pay to State Street
Bank and Trust  Company  or its  successor,  as its agent,  that  portion of the
principal of and  interest on the  security  that becomes due for payment but is
unpaid because of nonpayment by the issuer. Financial Guaranty Insurance Company
will make those  payments  to the agent on the date the  principal  or  interest
becomes due for payment or on the business day next  following  the day on which
Financial Guaranty Insurance Company receives notice of nonpayment, whichever is
later.
    

      The 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. However it will do so only upon receipt by the 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 the  principal  or interest due for payment
thereupon  shall vest in  Financial  Guaranty  Insurance  Company.  The proceeds
attributable to interest  payments will be tax-exempt.  Upon such payment by the
agent,  Financial  Guaranty Insurance Company will be fully subrogated to all of
the Fund's rights under the defaulted  obligation,  which  includes the right of
Financial  Guaranty  Insurance  Company to obtain payment from the issuer to the
extent of amounts paid by Financial Guaranty Insurance Company to the Fund.

Other Investment Techniques and Strategies.  In seeking its objective,  the Fund
may from time to time employ the types of investment  strategies and investments
described  below.  It is not required to use all of the  strategies at all times
and at times may not use them.

      |X| Floating  Rate and Variable  Rate  Obligations.  Variable  rate demand
obligations  have a demand feature that allows the Fund to tender the obligation
to the issuer or a third party prior to its  maturity.  The tender may be at par
value plus accrued interest, according to the terms of the obligation.

      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 91-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 not less 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 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  those  quality
standards.

      Floating rate and variable  rate demand notes that have a stated  maturity
in excess of one year may have  features  that  permit the holder to recover the
principal amount of the underlying security at specified intervals not exceeding
one year and upon not more than 30 days' notice. The issuer of that type of note
normally has a corresponding  right in its discretion,  after a given period, to
prepay  the  outstanding  principal  amount of the note plus  accrued  interest.
Generally  the issuer  must  provide a specified  number of days'  notice to the
holder.

      |X| Inverse  Floaters and Other Derivative  Investments.  Inverse floaters
may  offer  relatively  high  current  income,  reflecting  the  spread  between
long-term and short-term  tax exempt  interest  rates.  As long as the municipal
yield curve remains relatively steep and short-term rates remain relatively low,
owners  of  inverse  floaters  will have the  opportunity  to earn  interest  at
above-market  rates because they receive  interest at the higher long-term rates
but have paid for bonds with lower short-term rates. If the yield curve flattens
and shifts  upward,  an inverse  floater  will lose  value more  quickly  than a
conventional  long-term  bond. The Fund will invest in inverse  floaters to seek
higher  tax-exempt  yields than are available  from  fixed-rate  bonds that have
comparable maturities and credit ratings. In some cases the holder of an inverse
floater may have an option to convert the floater to a fixed-rate bond, pursuant
to a "rate-lock option."

      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  fluctuations.
"Embedded"  caps can be used to hedge a portion of the Fund's exposure to rising
interest  rates.  When  interest  rates exceed a  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.

      Inverse floaters are a form of derivative investment. Certain derivatives,
such as options,  futures, indexed securities and entering into swap agreements,
can be used to  increase or decrease  the Fund's  exposure to changing  security
prices,  interest  rates or other  factors that affect the value of  securities.
However,  these  techniques  could result in losses to the Fund,  if the Manager
judges  market  conditions  incorrectly  or  employs  a  strategy  that does not
correlate  well with the Fund's other  investments.  These  techniques can cause
losses if the counterparty does not perform its promises.  An additional risk of
investing in municipal securities that are 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.

      |X|  "When-Issued"  and  "Delayed-Delivery"  Transactions.  The  Fund  can
purchase  securities  on a  "when-issued"  basis,  and may purchase or sell such
securities   on  a   "delayed-delivery"   (or   "forward   commitment")   basis.
"When-issued"  or  "delayed-delivery"  refers  to  securities  whose  terms  and
indenture  are  available  and for  which a market  exists,  but  which  are not
available for immediate delivery.

      When  such  transactions  are  negotiated  the price  (which is  generally
expressed in yield terms) is fixed at the time the commitment is made.  Delivery
and  payment  for the  securities  take  place  at a later  date.  Normally  the
settlement  date is within six months of the  purchase  of  municipal  bonds and
notes.  However,  the Fund may, from time to time, purchase municipal securities
having a settlement  date more than six months and possibly as long as two years
or more after the trade date. The securities are subject to change in value from
market  fluctuation  during the settlement  period. The value at delivery may be
less than the  purchase  price.  For  example,  changes in  interest  rates in a
direction other than that expected by the Manager before  settlement will affect
the value of such securities and may cause loss to the Fund. No income begins to
accrue  to the  Fund on a when  issued  security  until  the Fund  receives  the
security at settlement of the trade.

      The Fund will engage in when-issued  transactions  in order to secure what
is considered to be an advantageous price and yield at the time of entering into
the  obligation.  When the  Fund  engages  in  when-issued  or  delayed-delivery
transactions,  it relies on the buyer or seller, as the case may be, to complete
the transaction. Its failure to do so may cause the Fund to lose the opportunity
to obtain the security at a price and yield it considers advantageous.

      When the Fund engages in when-issued and delayed-delivery transactions, it
does so for the purpose of acquiring or selling  securities  consistent with its
investment  objective and policies or for delivery pursuant to options contracts
it has entered into, and not for the purposes of investment  leverage.  Although
the Fund will enter into when-issued or delayed-delivery  purchase  transactions
to acquire securities, the Fund may dispose of a commitment prior to settlement.
If the Fund  chooses to dispose of the right to acquire a  when-issued  security
prior to its  acquisition  or to  dispose  of its right to  deliver  or  receive
against a forward commitment, it may incur a gain or loss.

      At the time the Fund makes a commitment  to purchase or sell a security on
a when-issued or forward  commitment  basis,  it records the  transaction on its
books and reflects the value of the security  purchased.  In a sale transaction,
it records the proceeds to be received,  in determining its net asset value. The
Fund will  identify  on its books  liquid  assets at least equal to the value of
purchase commitments until the Fund pays for the investment.

      When-issued  transactions and forward  commitments can be used by the Fund
as a defensive  technique to hedge against anticipated changes in interest rates
and  prices.  For  instance,  in periods of rising  interest  rates and  falling
prices,  the Fund might sell securities in its portfolio on a forward commitment
basis to attempt to limit its exposure to anticipated falling prices. In periods
of falling  interest  rates and  rising  prices,  the Fund might sell  portfolio
securities  and  purchase the same or similar  securities  on a  when-issued  or
forward commitment basis, to obtain the benefit of currently higher cash yields.

      |X| Puts and Standby Commitments.  When the Fund buys a municipal security
subject to a standby commitment to repurchase the security, the Fund is entitled
to same-day  settlement from the purchaser.  The Fund receives an exercise price
equal to the amortized cost of the underlying security plus any accrued interest
at the  time of  exercise.  A put  purchased  in  conjunction  with a  municipal
security  enables the Fund to sell the  underlying  security  within a specified
period of time at a fixed exercise price.

      The Fund might purchase a standby  commitment or put separately in cash or
it might  acquire the security  subject to the standby  commitment  or put (at a
price that reflects  that  additional  feature).  The Fund will enter into these
transactions  only with banks and  securities  dealers  that,  in the  Manager's
opinion,  present minimal credit risks.  The Fund's ability to exercise a put or
standby  commitment  will depend on the ability of the bank or dealer to pay for
the  securities if the put or standby  commitment  is exercised.  If the bank or
dealer should default on its  obligation,  the Fund might not be able to recover
all or a  portion  of any  loss  sustained  from  having  to sell  the  security
elsewhere.

      Puts and  standby  commitments  are not  transferable  by the  Fund.  They
terminate if the Fund sells the underlying  security to a third party.  The Fund
intends to enter into these  arrangements  to  facilitate  portfolio  liquidity,
although  such  arrangements  might  enable  the  Fund to sell a  security  at a
pre-arranged  price that may be higher than the  prevailing  market price at the
time the put or standby commitment is exercised. However, the Fund might refrain
from  exercising  a  put  or  standby   commitment  if  the  exercise  price  is
significantly  higher than the prevailing market price, to avoid imposing a loss
on the seller that could jeopardize the Fund's business  relationships  with the
seller.

      A put or standby commitment increases the cost of the security and reduces
the yield otherwise  available from the security.  Any consideration paid by the
Fund for the put or standby  commitment will be reflected on the Fund's books as
unrealized  depreciation  while the put or  standby  commitment  is held,  and a
realized  gain or loss  when the put or  commitment  is  exercised  or  expires.
Interest income received by the Fund from municipal  securities  subject to puts
or stand-by  commitments may not qualify as tax exempt in its hands if the terms
of the put or  stand-by  commitment  cause the Fund not to be treated as the tax
owner of the underlying municipal securities.

      |X|  Repurchase  Agreements.  The Fund may acquire  securities  subject to
repurchase  agreements.  It may do so for liquidity purposes to meet anticipated
redemptions of Fund shares, or pending the investment of the proceeds from sales
of Fund shares, or pending the settlement of portfolio securities transactions.

      In a  repurchase  transaction,  the Fund  acquires  a security  from,  and
simultaneously  resells it to an approved  vendor for delivery on an agreed upon
future  date.  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.  Approved  vendors  include U.S.  commercial
banks,  U.S.  branches  of  foreign  banks  or  broker-dealers  that  have  been
designated  a primary  dealer in  government  securities,  which meet the credit
requirements set by the Fund's Board of Trustees from time to time.

   
      The majority of these  transactions run from day to day. Delivery pursuant
to  resale  typically  will  occur  within  one to five  days  of the  purchase.
Repurchase  agreements  having a maturity  beyond  seven days are subject to the
Fund's  limits on  holding  illiquid  investments.  The Fund will not enter into
transactions  that will  cause more than 25% of the  Fund's  net  assets to be
subject to repurchase agreements.
    

      Repurchase  agreements,  considered  "loans" under the Investment  Company
Act,  are  collateralized  by the  underlying  security.  The Fund's  repurchase
agreements  require  that at all times  while  the  repurchase  agreement  is in
effect,  the  collateral's  value 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.  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.

      |X| Illiquid  and  Restricted  Securities.  To enable the Fund to sell its
holdings of a restricted  security not  registered  under the  Securities Act of
1933,  the Fund might  have to cause  those  securities  to be  registered.  The
expenses of registering restricted securities may be negotiated by the Fund with
the issuer at the time the Fund buys the securities.  When the Fund must arrange
registration because the Fund wishes to sell the security, a considerable period
may elapse  between the time the  decision is made to sell the  security and the
time the security is  registered  so that the Fund could sell it. The Fund would
bear the risks of any downward price fluctuation during that period.

      The Fund has percentage  limitations that apply to purchases of restricted
and  illiquid  securities,  as  stated  in  the  Prospectus.   Those  percentage
restrictions do not limit  purchases of restricted  securities that are eligible
for resale to qualified institutional purchasers pursuant to Rule 144A under the
Securities Act of 1933,  provided that those  securities have been determined to
be  liquid  by the  Board  of  Directors  of the Fund or by the  Manager.  Those
guidelines  take into account the trading  activity for such  securities and the
availability of reliable pricing information, among other factors. If there is a
lack of trading interest in a particular Rule 144A security,  the Fund's holding
of that security may be deemed to be illiquid.

      The  Fund  can  also  acquire   restricted   securities   through  private
placements.  Those  securities  have  contractual  restrictions  on their public
resale.  Those  restrictions  might  limit the Fund's  ability to dispose of the
securities and might lower the amount the Fund could realize upon the sale.

      |X| Loans of  Portfolio  Securities.  To attempt to raise  income or raise
cash for  liquidity  purposes,  the Fund may lend its  portfolio  securities  to
brokers, dealers and other financial institutions.  These loans cannot exceed 5%
of the value of the Fund's total assets.  The Fund  currently does not intend to
lend securities. There are risks in connection with securities lending. The Fund
might experience a delay in receiving additional collateral to secure a loan, or
a delay in recovery of the loaned securities.  Income from securities loans does
not  constitute  exempt-interest  income for the  purpose  of paying  tax-exempt
dividends.

      The Fund must receive  collateral  for a loan.  Under  current  applicable
regulatory  requirements (which are subject to change), on each business day the
loan collateral must be at least equal to the value of the loaned securities. It
must consist of cash, bank letters of credit,  securities of the U.S. government
or its agencies or  instrumentalities,  or other cash  equivalents  in which the
Fund is permitted to invest.  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. The terms of the letter of credit and the issuing bank both
must be satisfactory to the Fund.

      When it lends securities, the Fund receives amounts equal to the dividends
or  interest  on the  loaned  securities.  It 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 the loan  collateral.
Either  type of  interest  may be  shared  with the  borrower.  The Fund may pay
reasonable  finder's,  administrative  or other  fees in  connection  with these
loans.  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.

      |X|  Hedging.  The Fund can use  hedging to  attempt  to  protect  against
declines  in the  market  value of its  portfolio,  to permit the Fund to retain
unrealized gains in the value of portfolio securities that have appreciated,  or
to facilitate  selling  securities  for  investment  reasons.  To do so the Fund
could:
          |_| sell interest rate futures or municipal  bond index  futures,  
          |_| buy puts on such futures or securities, or
          |_| write  covered  calls on  securities,  interest  rate  futures  or
     municipal bond index futures. The Fund can also write covered calls on debt
     securities to attempt to increase the Fund's income,  but that income would
     not be  tax-exempt.  Therefore  it is  unlikely  that the Fund would  write
     covered calls for that purpose.

      The  Fund can  also  use  hedging  to  establish  a  position  in the debt
securities  market as a temporary  substitute  for  purchasing  individual  debt
securities.  In  that  case  the  Fund  would  normally  seek  to  purchase  the
securities,  and then terminate that hedging position. For this type of hedging,
the Fund could:
      |_| buy interest rate futures or municipal bond index futures,  or
      |_| buy calls on such futures or on securities.

      The Fund is not  obligated to use hedging  instruments,  even though it is
permitted  to use them in the  Manager's  discretion,  as described  below.  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.
The particular  hedging  instruments the Fund can use are described  below.  The
Fund may employ new hedging  instruments and strategies when they are developed,
if those investment methods are consistent with the Fund's investment objective,
are  approved  by its Board,  and are  permissible  under the Fund's  investment
restrictions and applicable regulations.

        |_|  Futures.  The Fund can buy and sell futures  contracts  relating to
debt  securities  (these are called  "interest rate futures") and municipal bond
indices (these are referred to as "municipal bond index futures"), but only as a
hedge against interest rate changes.

      An interest rate future obligates the seller to deliver (and the purchaser
to  take)  cash or a  specific  type of debt  security  to  settle  the  futures
transaction.  Either party could also enter into an offsetting contract to close
out the futures position.

      A "municipal bond index" assigns relative values to the municipal bonds in
the index, and is used 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 only in cash. The obligation  under the contract
may also be satisfied by entering into an offsetting  contract.  The  strategies
which the Fund  employs in using  municipal  bond index  futures  are similar to
those with regard to interest rate futures.

      No money is paid by or received  by the Fund on the  purchase or sale of a
futures  contract.  Upon entering into a futures  transaction,  the Fund will be
required  to  deposit  an  initial  margin  payment  in cash or U.S.  government
securities 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 daily.

      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 by their terms
call for  settlement  by the  delivery  of debt  securities,  in most  cases the
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.

      The Fund may  concurrently  buy and sell  futures  contracts in a strategy
anticipating  that the future the Fund  purchased  will perform  better than the
future the Fund sold. For example, the Fund might buy municipal bond futures and
concurrently  sell U.S.  Treasury Bond futures (a type of interest rate future).
The Fund would benefit if municipal bonds  outperform  U.S.  Treasury Bonds on a
duration-adjusted basis.

      Duration is a volatility  measure  that refers to the expected  percentage
change  in the  value of a debt  security  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 value of
the bond to fall about 3%.  There are risks  that this type of futures  strategy
will  not  be  successful.  U.S.  Treasury  bonds  might  perform  better  on  a
duration-adjusted basis than municipal bonds, and the assumptions about duration
that were used might be incorrect (for example,  the duration of municipal bonds
relative to U.S. Treasury Bonds might turn out to be greater than anticipated).

        |_| Put and Call Options. The Fund can buy and sell certain kinds of put
options  (puts)  and  call  options  (calls),   including   exchange-traded  and
over-the-counter  put  and  call  options.  These  can  include  index  options,
securities options and futures options. These strategies are described below.

   
     |_| Writing  Covered Call Options.  The Fund can write (that is, sell) call
options.  After the Fund  writes a call,  not more than 20% of the fund's  total
assets may be  subject to calls.  Each call the Fund  writes  must be  "covered"
while it is  outstanding.  That means the Fund must own the  investment on which
the call was written.  The Fund may write calls on futures contracts,  but if it
does not own the futures  contract or delivery  securities,  these calls must be
covered by securities  or other liquid assets that the Fund owns and  segregates
to enable it to satisfy its obligations if the call is exercised.
    

      When  the  Fund  writes  a  call  on  a  security,  it  receives  cash  (a
premium).The  Fund agrees to sell the underlying  investment to a purchaser of a
corresponding  call on the  same  security  during  the call  period  at a fixed
exercise price  regardless of market price changes  during the call period.  The
call period is usually not more than nine months.  The exercise price may differ
from the market price of the underlying security. The Fund has retained the risk
of loss that the price of the  underlying  security may decline  during the call
period. That risk may be offset to some extent by the premium the Fund receives.
If the value of the investment  does not rise above the call price, it is likely
that the call will lapse  without being  exercised.  In that case the Fund would
keep the cash premium and the investment.


      When the Fund writes a call on an index, it receives cash (a premium).  If
the buyer of the call exercises it, the Fund will pay an amount of cash equal to
the  difference  between the closing  price of the call and the exercise  price,
multiplied by the specified multiple that determines the total value of the call
for each point of difference. If the value of the underlying investment does not
rise above the call price,  it is likely that the call will lapse  without being
exercised. In that case the Fund would keep the cash premium.

      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 calls traded on exchanges,  or as to other acceptable escrow securities.
In that way, no margin will be required for such transactions.  OCC will release
the securities on the expiration of the calls or upon the Fund's entering into a
closing purchase transaction.

      When the Fund writes an  over-the-counter  ("OTC")  option,  it will enter
into an arrangement with a primary U.S. Government  securities dealer which will
establish  a formula  price at which the Fund  will have the  absolute  right to
repurchase  that OTC option.  The formula  price would  generally  be based on a
multiple of the premium  received  for the option,  plus the amount by which the
option is exercisable  below the market price of the  underlying  security (that
is, the option is  "in-the-money").  When the Fund writes an OTC option, it will
treat as illiquid (for purposes of its  restriction on illiquid  securities) the
mark-to-market  value of any OTC option held by it, unless the option is subject
to a buy-back  agreement by the executing  broker.  The  Securities and Exchange
Commission  is  evaluating  whether  OTC  options  should be  considered  liquid
securities.  The procedure  described  above could be affected by the outcome of
that evaluation.

      To  terminate  its  obligation  on a call it has  written,  the  Fund  may
purchase a corresponding call in a "closing purchase transaction." The Fund will
then realize a profit or loss,  depending  upon whether the net of the amount of
the option transaction costs and the premium received on the call the Fund wrote
was more or less than the price of the call the Fund  purchased to close out the
transaction.  A profit  may also be  realized  if the call  lapses  unexercised,
because the Fund retains the underlying investment and the premium received. Any
such profits are considered  short-term  capital gains for Federal tax purposes,
as are premiums on lapsed calls.  When  distributed by the Fund they are taxable
as ordinary income.

      The Fund may also write  calls on  futures  contracts  without  owning the
futures contract or securities  deliverable under the contract. To do so, at the
time the call is written,  the Fund must cover the call by segregating in escrow
an equivalent dollar value of 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.  Because  of  this  escrow  requirement,  in no
circumstances  would the Fund's receipt of an exercise  notice as to that future
put the Fund in a "short" futures position.

      |_| Writing Put Options.  The Fund can sell put  options.  A put option on
securities  gives the purchaser the right to sell, and the writer the obligation
to buy,  the  underlying  investment  at the  exercise  price  during the option
period.  The Fund  will not write  puts if,  as a  result,  more than 20% of the
Fund's  total  assets  would be  required  to be  segregated  to cover  such put
options.

      If the Fund  writes a put,  the put must be covered by  segregated  liquid
assets. The premium the Fund receives from writing a put represents a profit, as
long as the price of the  underlying  investment  remains  equal to or above the
exercise price of the put. However,  the Fund also assumes the obligation during
the option period to buy the underlying  investment from the buyer of the put at
the exercise price, even if the value of the investment falls below the exercise
price.  If a put the Fund has written expires  unexercised,  the Fund realizes a
gain in the amount of the premium less the transaction  costs  incurred.  If the
put is  exercised,  the  Fund  must  fulfill  its  obligation  to  purchase  the
underlying  investment at the exercise price. That price will usually exceed the
market value of the  investment at that time. In that case, the Fund may incur a
loss if it sells the underlying  investment.  That loss will be equal to the sum
of the sale price of the underlying  investment  and the premium  received minus
the sum of the exercise price and any transaction costs the Fund incurred.

      When writing a put option on a security,  to secure its  obligation to pay
for the underlying security the Fund will deposit in escrow liquid assets with a
value equal to or greater than the exercise price of the underlying  securities.
The Fund therefore forgoes the opportunity of investing the segregated assets or
writing calls against those assets.

      As long as the Fund's  obligation as the put writer  continues,  it may be
assigned an exercise notice by the broker-dealer through which the put was sold.
That notice will require the Fund to take  delivery of the  underlying  security
and pay the exercise price. The Fund has no control over when it may be required
to purchase the underlying security, since it may be assigned an exercise notice
at any time prior to the termination of its obligation as the writer of the put.
That obligation terminates upon expiration of the put. It may also terminate if,
before it receives  an  exercise  notice,  the Fund  effects a closing  purchase
transaction by purchasing a put of the same series as it sold. Once the Fund has
been  assigned  an  exercise  notice,   it  cannot  effect  a  closing  purchase
transaction.

      The Fund may decide to effect a closing purchase  transaction to realize a
profit on an outstanding  put option it has written or to prevent the underlying
security  from being put.  Effecting a closing  purchase  transaction  will also
permit  the Fund to write  another  put option on the  security,  or to sell the
security and use the proceeds from the sale for other investments. The Fund will
realize  a profit  or loss  from a closing  purchase  transaction  depending  on
whether the cost of the  transaction  is less or more than the premium  received
from  writing  the put option.  Any profits  from  writing  puts are  considered
short-term  capital gains for Federal tax purposes,  and when distributed by the
Fund, are taxable as ordinary income.

        |_|  Purchasing  Calls and Puts.  The Fund can buy calls on  securities,
broadly-based municipal bond indices,  municipal bond index futures and interest
rate  futures.  It can also buy  calls to close  out a call it has  written,  as
discussed  above.  Calls  the  Fund  buys  must be  listed  on a  securities  or
commodities  exchange,  or quoted on NASDAQ,  or traded in the  over-the-counter
market.  A call or put option may not be purchased  if the purchase  would cause
the  value of all the  Fund's  put and call  options  to  exceed 5% of its total
assets.

      When  the  Fund  purchases  a  call  (other  than  in a  closing  purchase
transaction),  it pays a premium. For calls on securities that the Fund buys, it
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.
The Fund  benefits  only if (1) the call is sold at a profit  or (2) the call is
exercised when the market price of the underlying investment is above the sum of
the exercise price plus the transaction  costs and premium paid for the call. If
the call is not either  exercised or sold (whether or not at a profit),  it will
become  worthless at its  expiration  date.  In that case the Fund will lose its
premium payment and the right to purchase the underlying investment.

      The Fund may buy puts on debt  securities,  municipal  bond  indices,  and
interest  rate or  municipal  bond  index  futures,  whether  or not it owns the
underlying  investment.  When the Fund  purchases a put, it pays a premium  and,
except as to puts on indices, has the right to sell the underlying investment to
a seller of a put on a corresponding investment during the put period at a fixed
exercise price. Puts on municipal bond indices are settled in cash.

      Buying a put on an  investment  the Fund does not own (such as an index or
future)  permits  the Fund  either  to resell  the put or to buy the  underlying
investment  and sell it at the  exercise  price.  The  resale  price  will  vary
inversely to the price of the underlying investment.  If the market price of the
underlying  investment is above the exercise price and, as a result,  the put is
not exercised, the put will become worthless on its expiration date.

      Buying a put on a debt  security,  interest rate future or municipal  bond
index  future the Fund owns  enables the Fund to protect  itself  during the put
period  against a decline in the value of the  underlying  investment  below the
exercise  price by selling the 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 date. In that case the
Fund  will  have  paid the  premium  but lost the  right to sell the  underlying
investment.  However,  the Fund may sell the put prior to its  expiration.  That
sale may or may not be at a profit

        |_| Risks of  Hedging  with  Options  and  Futures.  The use of  hedging
instruments requires special skills and knowledge of investment  techniques that
are  different  than what is required for normal  portfolio  management.  If the
Manager uses a hedging  instrument at the wrong time or judges market conditions
incorrectly, hedging strategies may reduce the Fund's returns.

      The Fund's option activities could 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 could pay a brokerage commission each time it buys a call or put,
sells a call, or buys or sells an underlying  investment in connection  with the
exercise of a call or put. Such commissions  might be higher on a relative basis
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.  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 investment.

      If a covered call written by the Fund is exercised on an  investment  that
has increased in value,  the Fund will be required to sell the investment at the
call  price.  It will not be able to realize  any profit if the  investment  has
increased in value above the call price.

      There is a risk in using short  hedging by selling  interest  rate futures
and municipal bond index futures or purchasing puts on municipal bond indices or
futures  to  attempt  to  protect  against  declines  in the value of the Fund's
securities.  The risk is that the prices of such futures or the applicable index
will  correlate  imperfectly  with the  behavior  of the cash (that is,  market)
prices of the Fund's securities. It is possible for example, that while the Fund
has used hedging  instruments in a short hedge, the market might advance and the
value of debt  securities held in the Fund's  portfolio  might decline.  If that
occurred,  the  Fund  would  lose  money  on the  hedging  instruments  and also
experience a decline in value of its debt securities.  However, while this could
occur over a 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.

      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 debt
securities  being hedged and movements in the price of the hedging  instruments,
the Fund might use  hedging  instruments  in a greater  dollar  amount  than the
dollar amount of debt securities being hedged.  It might do so if the historical
volatility of the prices of the debt securities being hedged is greater than the
historical volatility of the applicable index.

      The ordinary  spreads  between prices in the cash and futures  markets are
subject to distortions  due to differences in the natures of those markets.  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. 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 Fund can use  hedging  instruments  to  establish  a  position  in the
municipal  securities  markets as a  temporary  substitute  for the  purchase of
individual  securities  (long  hedging).  It is possible  that the market  might
decline.  If the Fund then concludes not to invest in such securities because of
concerns that there might be 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 purchase price of the securities.

      An  option  position  may be  closed  out only on a market  that  provides
secondary  trading for options of the same series.  There is no assurance that a
liquid  secondary market will exist for a particular  option.  If the Fund could
not effect a closing  purchase  transaction due to a lack of a market,  it would
have to hold the callable  investment until the call lapsed or was exercised and
could incur losses.

        |_| Interest Rate Swap Transactions.  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. Income from interest rate swaps may be taxable.

      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 can 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 under one or more swap transactions, the net amount payable on that date
shall be paid. In addition, the master netting agreement may provide that if one
party  defaults  generally or on one swap,  the  counterparty  can terminate the
swaps with that party.  Under master netting  agreements,  if there is a default
resulting  in a loss to one  party,  that  party's  damages  are  calculated  by
reference to the average cost of a  replacement  swap with respect to 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."

        |_| Regulatory  Aspects of Hedging  Instruments.  When using futures and
options on futures,  the Fund is required to operate within  certain  guidelines
and restrictions  established by the Commodity  Futures Trading  Commission (the
"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.  That 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 options 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  options on futures  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 the option exchanges.  The exchanges limit the maximum number of options that
may be  written or held by a single  investor  or group of  investors  acting in
concert.  Those limits apply  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  that 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.

      Under the Investment Company Act, when the Fund purchases an interest rate
future  or  municipal  bond  index  future,  it must  maintain  cash or  readily
marketable short-term debt instruments in an amount equal to the market value of
the investments underlying the future, less the margin deposit applicable to it.

      |X|   Temporary  Defensive  Investments.  The  securities  the  Fund can
invest in for temporary defensive purposes include the following:
      |_|   short-term municipal securities;
     |_| obligations issued or guaranteed by the U.S. government or its agencies
or instrumentalities;
     |_| corporate  debt  securities  rated within the three highest grades by a
nationally recognized rating agency;
      |_| commercial  paper  rated  "A-1" by S&P,  or a  comparable  rating by
another nationally recognized rating agency; and
      |_| certificates of deposit of domestic banks with assets of $1 billion or
more.

      |X| Taxable Investments.  While the Fund can invest up to 20% of its total
assets in investments  that generate income subject to income taxes, it does not
anticipate  investing  substantial  amounts of its assets in taxable investments
under normal market  conditions or as part of its normal trading  strategies and
policies. To the extent it invests in taxable securities,  the Fund would not be
able to meet its objective of providing  tax exempt income to its  shareholders.
Taxable  investments  include,  for  example,  hedging  instruments,  repurchase
agreements, and some of the types of securities the Fund could buy for temporary
defensive purposes.

Investment Restrictions

      |X|  What Are  "Fundamental  Policies?"  Fundamental  policies  are  those
policies that the Fund has adopted to govern its investments that can be changed
only by the vote of a "majority" of the Fund's  outstanding  voting  securities.
Under the Investment  Company Act, such a "majority" vote is defined as the vote
of the holders of the lesser of:
 |_|  67% or more of the shares present or represented by proxy at a shareholder
      meeting,  if the  holders of more than 50% of the  outstanding  shares are
      present or represented by proxy, or
 |_|  more than 50% of the outstanding shares.

      The Fund's investment  objective is a fundamental  policy.  Other policies
described in the  Prospectus  or this  Statement of Additional  Information  are
"fundamental"  only if they are identified as such. The Fund's Board of Trustees
can change  non-fundamental  policies  without  shareholder  approval.  However,
significant  changes to investment  policies will be described in supplements or
updates to the  Prospectus  or this  Statement  of  Additional  Information,  as
appropriate.  The Fund's most significant  investment  policies are described in
the Prospectus.

      |_| The Fund cannot invest in real estate. However, the Fund can invest in
municipal  securities or other permissible  securities or instruments secured by
real estate or interests in real estate.

      |_| The Fund cannot  invest in  interests  in oil,  gas, or other  mineral
exploration or development programs.

      |_| The Fund cannot purchase securities, or other instruments,  on margin.
However, the Fund can invest in options, futures, options on futures and similar
instruments  and may make margin  deposits and payments in connection with those
investments.

      |_|   The Fund cannot make short sales of securities.

      |_| The Fund cannot underwrite securities. A permitted exception is in the
case it is deemed to be an  underwriter  under the  Securities  Act of 1933 when
reselling securities held in its portfolio.

      |_| The Fund cannot invest in securities  of other  investment  companies,
except  if they  are  acquired  as  part of a  merger,  consolidation  or  other
acquisition.

      |_| The Fund cannot 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 except to secure a borrowing,
and in that case no more than 10% of the Fund's  total  assets  may be  pledged,
mortgaged or hypothecated. 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 can enter into when-issued and  delayed-delivery  transactions as described
in this Statement of Additional Information.

      |_| The Fund  cannot make loans.  However,  the Fund can  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.

      |_|  With  respect  to  75% of its  total  assets,  the  Fund  cannot  buy
securities issued or guaranteed by any one issuer (except the U.S. Government or
any of its  agencies or  instrumentalities)  if 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.

      |_| The Fund cannot  invest more than 25% of its total  assets in a single
industry.  As an operating  policy,  the Fund applies this restriction to 25% or
more of its total  assets.  However,  the Fund can  invest  more than 25% of its
assets in a particular  segment of the  municipal  bond market,  but it will not
invest more than 25% of its total assets in  industrial  development  bonds in a
single industry.

      |_| The Fund cannot make investments for the purpose of exercising control
of management.

      |_| The Fund  cannot  purchase  securities  of any  issuer  if,  officers,
trustees and directors of the Fund or the Manager individually  beneficially own
more than .5% of the  securities  of that issuer and together  own  beneficially
more than 5% of the outstanding securities of that issuer.

      |_| The Fund cannot issue "senior  securities," but this does not prohibit
certain  investment  activities  for which assets of the Fund are  designated as
segregated or margin collateral or escrow  arrangements are established to cover
the related  obligations.  Examples of those activities include borrowing money,
reverse repurchase agreements, delayed-delivery and when-issued arrangements for
portfolio  securities  transactions,  and contracts to buy or sell  derivatives,
hedging instruments, options or futures.

     The Fund will not purchase or retain  securiites if, as a result,  the Fund
would have more than 5% of its total assets  invested in  securities  of private
issuers haveing a record of less than three years' continuous  operation,  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,  unless the
security is rated by a nationally-recognized  rating service. In each case, that
period may  include the  operation  of  predecessor  companies  or  enterprises.
Additionally, the Fund willnot invest in common stock or any warrants related to
common stocks. These operating policies are not fundamental policies.

      Unless the Prospectus or Statement of Additional Information states that a
percentage  restriction applies on an ongoing basis, it applies only at the time
the Fund makes an investment.  In that case 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.

Diversification.  The  Fund  intends  to be  "diversified"  as  defined  in  the
Investment  Company Act and to satisfy the  restrictions  against  investing too
much of its assets in any "issuer" as set forth in the  restrictions  above.  In
implementing  this  policy,  the  identification  of the  issuer of a  municipal
security  depends on the terms and  conditions of the security.  When the assets
and  revenues  of an  agency,  authority,  instrumentality  or  other  political
subdivision  are  separate  from  those of the  government  creating  it and the
security is backed only by the assets and revenues of the  subdivision,  agency,
authority or instrumentality,  the latter would be deemed to be the sole issuer.
Similarly,  if an industrial  development  bond is backed only by the assets and
revenues of the non-governmental  user, then that user would be deemed to be the
sole issuer.  However,  if in either case the creating  government or some other
entity  guarantees  a security,  the  guarantee  would be  considered a separate
security and would be treated as an issue of such government or other entity.

Applying the Restriction Against  Concentration.  To implement its policy not to
concentrate its investments,  the Fund has adopted the industry  classifications
set forth in  Appendix B to this  Statement  of  Additional  Information.  Those
industry classifications are not a fundamental policy.

      In implementing the Fund's policy not to concentrate its investments,  the
Manager  will  consider  a  non-governmental  user  of  facilities  financed  by
industrial  development  bonds as being in a particular  industry.  That is done
even  though  the bonds are  municipal  securities,  as to which the Fund has no
concentration  limitation.   Although  this  application  of  the  concentration
restriction  is not a  fundamental  policy of the Fund,  it will not be  changed
without shareholder approval.

How the Fund Is Managed

Organization  and  History.  The  Fund  is  one of  two  diversified  investment
portfolios or "series" of Oppenheimer  Municipal Fund, an open-end,  diversified
management  investment  company  organized as a Massachusetts  business trust in
1986, with an unlimited number of authorized shares of beneficial interest.

      Oppenheimer Municipal Fund (and therefore, the Fund, as one of its series)
is governed by a Board of Trustees,  which is  responsible  for  protecting  the
interests  of   shareholders   under   Massachusetts   law.  The  Trustees  meet
periodically  throughout the year to oversee the Fund's  activities,  review its
performance,  and review the actions of the Manager.  Although the Fund will not
normally  hold annual  meetings  of its  shareholders,  it may hold  shareholder
meetings from time to time on important  matters.  Shareholders  of  Oppenheimer
Municipal  Fund have the right to call a meeting  to remove a Trustee or to take
other action described in the Declaration of Trust.

      |X|  Classes  of Shares.  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 classes invest in the same investment
portfolio.  Shares  are  freely  transferable.   Each  share  has  one  vote  at
shareholder  meetings,  with fractional shares voting  proportionally on matters
submitted to the vote of shareholders. Each class of shares:
      |_|               has its own dividends and distributions,
      |_|                 pays certain  expenses  which may be  different  for
   the different classes,
      |_|                 may have a different net asset value,
      |_|                 may have separate  voting rights on matters in which
         the  interests  of one  class are  different  from the  interests  of
         another class, and
      |_|                 votes as a class on matters  that  affect that class
alone.

      |X|  Meetings of  Shareholders.  As a series of a  Massachusetts  business
trust,  the Fund is not  required  to hold,  and does not plan to hold,  regular
annual meetings of shareholders. The Fund will hold meetings when required to do
so by the  Investment  Company Act or other  applicable  law. It will also do so
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 Oppenheimer  Municipal Fund, 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  Oppenheimer  Municipal  Fund. If the Trustees  receive a
request from at least 10 shareholders stating that they wish to communicate with
other  shareholders to request a meeting to remove a Trustee,  the Trustees will
then either make the shareholder lists of a series of Oppenheimer Municipal Fund
available  to  the  applicants  or  mail  their   communication   to  all  other
shareholders at the applicants'  expense.  The  shareholders  making the request
must have been  shareholders  for at least six months and must hold  shares of a
series of Oppenheimer  Municipal Fund valued at $25,000 or more or  constituting
at least 1% of the outstanding shares of Oppenheimer  Municipal Fund,  whichever
is less.  The Trustees may also take other action as permitted by the Investment
Company Act.

      |X| Shareholder and Trustee  Liability.  The Declaration of Trust contains
an  express  disclaimer  of  shareholder  or  Trustee  liability  for the Fund's
obligations.  It also provides for indemnification and reimbursement of expenses
out of the Fund's  property for any shareholder  held personally  liable for its
obligations.  The  Declaration of Trust also states that upon request,  the Fund
shall assume the defense of any claim made against a shareholder  for any act or
obligation   of  the  Fund  and  shall  satisfy  any  judgment  on  that  claim.
Massachusetts  law  permits  a  shareholder  of a  business  trust  to  be  held
personally liable as a "partner" under certain circumstances.  However, the risk
that a Fund  shareholder  will incur  financial loss from being held liable as a
"partner" of the Fund is limited to the relatively remote circumstances in which
the Fund would be unable to meet its obligations.

      The Fund's  contractual  arrangements state that any person doing business
with the Fund (and each shareholder of the Fund) agrees under the Declaration of
Trust to look solely to the assets of the Fund for  satisfaction of any claim or
demand that may arise out of any dealings with the Fund.  The contracts  further
state that the Trustees shall have no personal  liability to any such person, to
the extent permitted by law.

(2)   For the 1998 calendar year.

      |X| Deferred  Compensation  Plan for  Trustees.  The Board of Trustees has
adopted a Deferred  Compensation  Plan for  disinterested  trustees that enables
them 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 level of
compensation  to any Trustee.  Pursuant to an Order issued by the Securities and
Exchange  Commission,  the Fund may invest in the funds  selected by the Trustee
under  the  plan  without  shareholder  approval  for  the  limited  purpose  of
determining the value of the Trustee's deferred fee account.

      |X| Major Shareholders.  As of January 4, 1999, the only persons who owned
of record or who were  known by the Fund to own  beneficially  5% or more of the
Fund's outstanding shares were:

 Merrill Lynch  Pierce  Fenner & Smith Inc.  (which  advised  the Fund that such
      shares  were held  beneficially  for its  customers)  4800 Deer Lake Drive
      East, Floor 3, Jacksonville,  Florida 32246, which owned 101,068.085 Class
      B shares  (approximately  6.32% of the Class B shares then outstanding)and
      69,127.099 Class C shares (approximately 22.11% of the Class C shares then
      outstanding).

      Margie H. Madak Trustee V/A 8/22/91 FBO
      Margie H. Madak,  8619 W. Sunnyside Avenue,  Chicago,  IL 60656, who owned
      28,611.084 Class C shares  (approximately 9.15% of the Class C shares then
      outstanding).

The Manager.  The Manager is  wholly-owned by Oppenheimer  Acquisition  Corp., a
holding company controlled by Massachusetts  Mutual Life Insurance Company.  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| The Investment  Advisory  Agreement.  The Manager provides  investment
advisory  and  management  services  to the Fund  under an  investment  advisory
agreement  between the Manager and the Fund. The Manager selects  securities for
the Fund's portfolio and handles its day-to day business.  The portfolio manager
of the Fund is  employed  by the  Manager  and is the person who is  principally
responsible for the day-to-day  management of the Fund's  investment  portfolio.
Other members of the Manager's Fixed-Income Portfolio Team provide the portfolio
manager  with  research  and counsel in  managing  the Fund's  investments.  The
agreement  requires  the  Manager,  at its  expense,  to  provide  the Fund with
adequate office space, facilities and equipment. It also requires the Manager to
provide  and  supervise  the  activities  of  all  administrative  and  clerical
personnel required to provide effective  corporate  administration for the Fund.
Those  responsibilities  include the compilation and maintenance of records with
respect to the  Fund's  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.

      The Fund pays  expenses  not  expressly  assumed by the Manager  under the
advisory  agreement.  The advisory  agreement lists examples of expenses paid by
the Fund. The major categories relate to interest,  taxes, fees to disinterested
Trustees, legal and audit expenses, custodian and transfer agent expenses, share
issuance costs, certain printing and registration costs,  brokerage commissions,
and non-recurring expenses, including litigation costs. The management fees paid
by the  Fund  to the  Manager  are  calculated  at the  rates  described  in the
Prospectus, which are applied to the assets of the Fund as a whole. The fees are
allocated  to each class of shares  based upon the  relative  proportion  of the
Fund's net assets  represented by that class.  The  management  fees paid by the
Fund to the Manager during its last three fiscal years are listed below.

      The investment  advisory  agreement  states that in the absence of willful
misfeasance,  bad faith,  gross negligence in the performance of its duties,  or
reckless disregard for its obligations and duties under the investment  advisory
agreement,  the  Manager is not liable for any loss  sustained  by reason of any
investment of the Fund assets made with due care and in good faith.

      The  agreement  permits the Manager to act as  investment  adviser for any
other person,  firm or corporation.  The Manager uses the name  "Oppenheimer" in
connection with other  investment  companies for which it or an affiliate is the
investment adviser or general distributor. If the Manager shall no longer act as
investment  adviser to the Fund,  the Manager can withdraw its permission to the
Fund (and to Oppenheimer  Municipal Fund) to use the name  "Oppenheimer" as part
of its name.

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 buy and sell portfolio
securities for the Fund. The investment advisory agreement allows the Manager to
use  broker-dealers  to effect  the  Fund's  portfolio  transactions.  Under the
agreement,  the Manager may employ those broker-dealers  (including "affiliated"
brokers,  as that term is defined in the  Investment  Company Act) that,  in the
Manager's best judgment based on all relevant factors, will implement the Fund's
policy to obtain,  at  reasonable  expense,  the "best  execution"  of portfolio
transactions.  "Best execution"  refers to prompt and reliable  execution at the
most  favorable  price  obtainable.   The  Manager  need  not  seek  competitive
commission bidding. However, the Manager 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 investment  advisory  agreement,  the Manager may select brokers
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  charge,  if  the  Manager  makes  a good  faith  determination  that  the
commission is fair and reasonable in relation to the services provided.  Subject
to those other  considerations,  as a factor in selecting brokers for the Fund's
portfolio  transactions,  the Manager may also  consider  sales of shares of the
Fund and other investment companies managed by the Manager or its affiliates.

Brokerage Practices Followed by the Manager. The Manager allocates brokerage for
the Fund subject to the provisions of the investment  advisory agreement and the
procedures and rules described above.  Generally the Manager's portfolio traders
allocate brokerage upon  recommendations  from the Manager's portfolio managers.
In certain instances,  portfolio managers may directly place trades and allocate
brokerage.  In either case,  the  Manager's  executive  officers  supervise  the
allocation of brokerage.

      Most securities  purchases made by the Fund are in principal  transactions
at net prices.  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 the Manager determines that a better price or execution may
be obtained  by using the  services  of a broker.  Therefore,  the Fund does not
incur  substantial   brokerage  costs.   Portfolio   securities  purchased  from
underwriters  include  a  commission  or  concession  paid by the  issuer to the
underwriter in the price of the security.  Portfolio  securities  purchased 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. In an option  transaction,  the Fund ordinarily uses the same broker
for the purchase or sale of the option and any  transaction in the investment to
which the option  relates.  Other funds  advised by the Manager have  investment
objectives  and  policies  similar to those of the Fund.  Those  other funds may
purchase or sell the same  securities  as the Fund at the same time as the Fund,
which could affect the supply and price of the  securities.  When possible,  the
Manager tries to combine concurrent orders to purchase or sell the same security
by more than one of the accounts  managed by the Manager or its affiliates.  The
transactions  under those combined orders are averaged as to price and allocated
in accordance with the purchase or sale orders actually placed for each account.

      The  investment   advisory  agreement  permits  the  Manager  to  allocate
brokerage for research services.  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.  Investment  research  received  by the  Manager  for  the
commissions  paid by those other accounts may be useful both to the Fund and one
or more of the Manager's other  accounts.  Investment  research  services may be
supplied  to the Manager by a third  party at the  instance of a broker  through
which trades are placed.  Investment  research services include  information and
analyses on particular  companies  and  industries as well as market or economic
trends and portfolio  strategy,  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 stated  commissions  on
secondary fixed-income agency trades to obtain research if the broker represents
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 Board of Trustees has permits the Manager to use  concessions on fixed-price
offerings  to obtain  research,  in the same manner as is  permitted  for agency
transactions.

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

Distribution and Service Plans

The Distributor.  Under its General  Distributor's  Agreement with the Fund, the
Distributor  acts as the Fund's principal  underwriter in the continuous  public
offering of the different  classes of shares of the Fund. The Distributor is not
obligated to sell a specific number of shares. Expenses normally attributable to
sales are borne by the Distributor.

      The compensation paid to (or retained by) the Distributor from the sale of
shares or on the redemption of shares is discussed in the table below:

Distribution  and Service  Plans.  The Fund has  adopted a Service  Plan for its
Class A shares and  Distribution  and Service  Plans for its Class B and Class C
shares under Rule 12b-1 of the Investment  Company Act.  Under those plans,  the
Fund makes  payments to the  Distributor  in  connection  with the  distribution
and/or servicing of the shares of the particular class.

      Each  plan has been  approved  by a vote of the Board of  Trustees  of the
Fund,  including a majority of the  Independent  Trustees,o  cast in person at a
meeting  called for the purpose of voting on that plan.  Each plan has also been
approved by a vote of the holders of a "majority"  (as defined in the Investment
Company  Act) of the shares of each class.  The Manager cast the vote to approve
the Class C plan as the sole initial holder of Class C shares.

o In  accordance  with  Rule  12b-1  of the  Investment  Company  Act,  the term
"Independent  Trustees" in this  Statement of Additional  Information  refers to
those Trustees who are not "interested  persons" of the Fund or its parent trust
and who do not have any direct or indirect  financial  interest in the operation
of the distribution plan or any agreement under the plan.

      Under the plans the Manager and the Distributor, in their sole discretion,
from time to time may use their own resources (at no direct cost to the Fund) to
make  payments  to  brokers,   dealers  or  other  financial   institutions  for
distribution  and  administrative  services  they  perform.  The Manager may use
profits from the advisory fee it receives from the Fund. The Distributor and the
Manager  may,  in their sole  discretion,  increase  or  decrease  the amount of
payments they make to plan recipients from their own resources.

      Unless a plan is  terminated  as described  below,  the plan  continues in
effect  from year to year,  but only if the  Fund's  Board of  Trustees  and its
Independent  Trustees  specifically  vote  annually to approve its  continuance.
Approval must be by a vote cast in person at a meeting called for the purpose of
voting on continuing  the plan. A 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.

      The  Board  and  the  Independent   Trustees  must  approve  all  material
amendments to a plan. An amendment to increase materially the amount of payments
to be made under the plan must be approved by shareholders of the class affected
by the  amendment.  Because  Class B shares  automatically  convert into Class A
shares  after six years,  the Fund must obtain the  approval of both Class A and
Class B shareholders  for an amendment to the Class A plan that would materially
increase  the  amount to be paid under that  plan.  That  approval  must be by a
"majority"  (as  defined in the  Investment  Company  Act) of the shares of each
class, voting separately by Class.

      While the plans are in effect,  the  Treasurer  of the Fund shall  provide
separate  written  reports on the plans to the Fund's Board of Trustees at least
quarterly  for its review.  The reports  shall detail the amount of all payments
made under a plan and the purpose for which the payments  were made.  The report
on  the  Class  B and  Class  C  plans  shall  also  include  the  Distributor's
distribution  costs for the quarter,  and any costs for previous  fiscal periods
that have been  carried  forward.  Those  reports  are subject to the review and
approval of the Independent Trustees in the exercise of their fiduciary duty.

      Each plan states that while it is in effect,  the selection or replacement
and nomination of those Trustees of the Fund who are not "interested persons" of
the Fund is  committed  to the  discretion  of the  Independent  Trustees.  This
provision  does not  prevent  the  involvement  of others in the  selection  and
nomination  process as long as the final  decision as to selection or nomination
is approved by a majority of the Independent Trustees.

      Under the plan for a class,  no payment  will be made to any  recipient in
any  quarter in which the  aggregate  net asset value of all Fund shares held by
the recipient for itself and its customers does not exceed a minimum amount,  if
any,  that may be set from time to time by a majority of the Fund's  Independent
Trustees.  The Board of Trustees  has set the fees at the maximum  rate  allowed
under  the plans and has set no  minimum  asset  amount  needed to  qualify  for
payments.

      |X| Class A Service Plan.  Under the Class A service plan, the Distributor
currently  uses the fees it receives  from the Fund to pay brokers,  dealers and
other financial institutions (they are referred to as "recipients") for personal
services and account  maintenance  services they provide for their customers who
hold Class A shares.  The services  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.  The Distributor  makes
payments to plan  recipients  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
provider or their customers.

      For the fiscal year ended September 30, 1998,  payments under the Plan for
Class A shares  totaled  $231,419,  all of which was paid by the  Distributor to
recipients.  That included $11,269 paid to an affiliate of the Distributor.  Any
unreimbursed  expenses the Distributor incurs with respect to Class A shares for
any fiscal year may not be recovered in subsequent  years.  The  Distributor may
not use  payments  received  under the  Class A plan to pay any of its  interest
expenses, carrying charges, other financial costs, or allocation of overhead.

      |X| Class B and Class C Service and Distribution  Plans.  Under each plan,
service fees and distribution  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 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 under
the  plans  during  that  period.  The  Class B and  Class C  plans  permit  the
Distributor to retain both the asset-based  sales charges and the service fee on
shares or to pay  recipients  the  service  fee on a  quarterly  basis,  without
payment in advance. The types of services that recipients provide are similar to
the services provided under the Class A plan, described above.

      The  Distributor  presently  intends to pay  recipients the service fee on
Class B and  Class C  shares  in  advance  for the  first  year the  shares  are
outstanding.  After the first year shares are outstanding, the Distributor makes
payments  quarterly  on those  shares.  The advance  payment is based on the net
asset value of shares sold.  Shares  purchased by exchange do not qualify for an
advance  service fee payment.  If Class B or Class C shares are redeemed  during
the first year after their purchase,  the recipient of the service fees on those
shares will be  obligated  to repay the  Distributor  a pro rata  portion of the
advance payment made on those shares.

      The Distributor  retains the  asset-based  sales charge on Class B shares.
The Distributor  retains the  asset-based  sales charge on Class C shares during
the first year the shares are outstanding.  It pays the asset-based sales charge
as an ongoing  commission to the dealer on Class C shares outstanding for a year
or  more.  If a  dealer  has a  special  agreement  with  the  Distributor,  the
Distributor will pay the Class B and/or Class C service fees and the asset-based
sales charge to the dealer  quarterly in lieu of paying the sales commission and
service fee in advance at the time of purchase.

      The  asset-based  sales  charge  on  Class  B and  Class C  shares  allows
investors to buy shares  without a front-end  sales  charge  while  allowing the
Distributor  to  compensate  dealers that sell those shares.  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 plans. The Fund pays the asset-based
sales charge to the Distributor for its services rendered in distributing  Class
B and Class C shares.  The payments are made to the  Distributor  in recognition
that the Distributor:
      |_|pays sales  commissions  to authorized  brokers and dealers at the time
         of sale and pays service fees as described in the Prospectus,
      |_|may  finance  payment of sales  commissions  and/or the  advance of the
         service fee payment to recipients  under the plans, or may provide such
         financing from its own resources or from the resources of an affiliate,
      |_|   employs personnel to support distribution of shares, and
      |_|   bears 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.

      Payments  made under the Class B plan for the fiscal year ended  September
30,  1998,  totaled  $237,967  (including  $2,503  paid to an  affiliate  of the
Distributor). The Distributor retained $197,544 of the total paid. Payments made
under the Class C Plan for the fiscal  year ended  September  30,  1998  totaled
$36,548  (including  $134  paid  to  an  affiliate  by  the  Distributor).   The
Distributor  retained  $25,438 of the total paid.  At September  30,  1998,  the
Distributor  had incurred  unreimbursed  expenses  under the Class B plan in the
amount of $875,951 (equal to 3.20% of the Fund's net assets represented by Class
B shares on that date).  At September  30, 1998,  the  Distributor  had incurred
unreimbursed  expenses  under the Class C plan of $67,456 (equal to 1.37% of the
Fund's net assets represented by Class C shares on that date). 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 the Distributor to compensate it for
its expenses incurred for distributing shares before the plan was terminated.

      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 to NASD members.

Performance of the Fund

Explanation  of  Performance  Terminology.  The Fund uses a variety  of terms to
illustrate  its   performance.   These  terms  include   "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."  An  explanation  of how  yields  and total
returns are  calculated  is set forth  below.  The charts  below show the Fund's
performance  as of its most  recent  fiscal  year end.  You can  obtain  current
performance  information by calling the Fund's Transfer Agent at  1-800-525-7048
or    by    visiting    the    OppenheimerFunds    Internet    web    site    at
http://www.oppenheimerfunds.com.

      The Fund's  illustrations of its performance data in  advertisements  must
comply  with  rules of the  Securities  and  Exchange  Commission.  Those  rules
describe  the  types of  performance  data  that may be used and how it is to be
calculated.  In general,  any  advertisement by the Fund of its performance data
must include the average annual total returns for the advertised class of shares
of the Fund.  Those  returns must be shown 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  (or its submission for
publication).  Certain types of yields may also be shown, provided that they are
accompanied by standardized average annual total returns.

      Use of  standardized  performance  calculations  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 the
Fund's performance information as a basis for comparison with other investments:
      |_| Yields and total returns  measure the  performance  of a  hypothetical
account in the Fund over various periods and do not show the performance of each
shareholder's  account.  Your  account's  performance  will  vary from the model
performance  data if your  dividends  are  received in cash,  or you buy or sell
shares  during the period,  or you bought  your  shares at a different  time and
price than the shares used in the model.
      |_|   The Fund's performance  returns do not reflect the effect of taxes
on distributions.
      |_|   An  investment in the Fund is not insured by the FDIC or any other
government agency.
      |_| The  principal  value of the Fund's  shares,  and its yields and total
returns are not guaranteed and normally will fluctuate on a daily basis.
      |_| When an investor's shares are redeemed, they may be worth more or less
than their original cost.
      |_|  Yields  and  total  returns  for  any  given  past  period  represent
historical performance information and are not, and should not be considered,  a
prediction of future yields or returns.

      The performance of each class of shares is shown  separately,  because the
performance  of each class of shares will usually be different.  That is because
of the  different  kinds of  expenses  each  class  bears.  The yields and total
returns of each class of shares of the Fund are  affected by market  conditions,
the quality of the Fund's  investments,  the maturity of those investments,  the
types of  investments  the  Fund  holds,  and its  operating  expenses  that are
allocated to the particular class.

      |X| Yields.  The Fund uses a variety of different yields to illustrate its
current returns. Each class of shares calculates its yield separately because of
the different expenses that affect each class.

        |_| Standardized Yield. The "standardized  yield" (sometimes referred to
just 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.

      Standardized  yield 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:

- ------------------------------------------------------------------------------
                                             a-b       6
                   Standardized Yield = 2 ((------ + 1) - 1)
                                              cd
        
- ------------------------------------------------------------------------------
      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 assumptions).

      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 particular 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.

        |_| Dividend Yield. The Fund may quote a "dividend yield" for each class
of its  shares.  Dividend  yield is based  on the  dividends  paid on a class of
shares 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 current 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.

        |_|  Tax-Equivalent  Yield.  The  "tax-equivalent  yield"  of a class of
shares  is the  equivalent  yield  that  would  have to be  earned  on a taxable
investment  to  achieve  the  after-tax   results   represented  by  the  Fund's
tax-equivalent  yield. It adjusts the Fund's  standardized  yield, as calculated
above, by a stated Federal tax rate. Using different tax rates to show different
tax  equivalent  yields  shows  investors  in  different  tax  brackets  the tax
equivalent yield of the Fund based on their own tax bracket.

      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. The result is added 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.  Your tax bracket is determined by your 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.

      |X| Total Return Information. There are different types of "total returns"
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
and that  the  investment  is  redeemed  at the end of the  period.  Because  of
differences  in expenses  for each class of shares,  the total  returns for each
class are separately  measured.  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 actual  year-by-year  performance.  The
Fund uses  standardized  calculations for its total returns as prescribed by the
SEC. The methodology is discussed below.

            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 without sales charge,
as described below).  For Class B shares,  payment of the applicable  contingent
deferred  sales charge is applied,  depending on the period for which the return
is shown: 5.0% in the first year, 4.0% in the second year, 3.0% in the third and
fourth  years,  2.0%  in the  fifth  year,  1.0%  in the  sixth  year  and  none
thereafter.  For Class C shares,  the 1%  contingent  deferred  sales  charge is
deducted for returns for the 1-year period.

        |_| Average  Annual Total Return.  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" in the
formula) of that investment, according to the following formula:

- ------------------------------------------------------------------------------
                    ( ERV ) 1/n
                    (-----) -1 = Average Annual Total Return
                    (  P  )
                               
- ------------------------------------------------------------------------------
        |_| Cumulative Total Return.  The "cumulative total return"  calculation
measures  the change in 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
                             ------- = Total Return
                                P
                                
- ------------------------------------------------------------------------------
        |_| Total  Returns  at Net Asset  Value.  From time to time the Fund may
also quote a cumulative  or an average  annual total return "at net asset value"
(without  deducting sales charges) 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

Other  Performance  Comparisons.  The Fund compares its performance  annually to
that of an  appropriate  broadly  based  market  index in its  Annual  Report to
shareholders.  You can obtain that  information by contacting the Transfer Agent
at the addresses or telephone  numbers  shown on the cover of this  Statement of
Additional  Information.  The Fund may also compare its  performance  to that of
other  investments,  including  other  mutual  funds,  or  use  rankings  of its
performance  by  independent  ranking  entities.  Examples of these  performance
comparisons are set forth below.

      |X| Lipper Rankings. 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"). Lipper is 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 by Lipper  against all other insured  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.  Lipper also publishes  "peer-group"
indices of the  performance  of all mutual funds in a category  that it monitors
and averages of the performance of the funds in particular categories.

      |X| Morningstar Rankings.  From time to time the Fund may publish the star
ranking of the  performance  of its classes of 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.  The Fund is ranked among municipal
bond funds.

      Morningstar  star  rankings are based on  risk-adjusted  total  investment
return.  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 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%
of funds in a category), 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 date 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.

      |X|   Performance   Rankings  and   Comparisons   by  Other  Entities  and
Publications.  From time to time the Fund may include in its  advertisements and
sales literature performance  information about the Fund cited in newspapers and
other periodicals such as The New York Times, The Wall Street Journal, Barron's,
or similar  publications.  That information 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 the
performance  of various  market  indices  or other  investments,  and  averages,
performance  rankings or other  benchmarks  prepared by  recognized  mutual fund
statistical services.

      Investors  may also wish to compare the Fund's Class A, Class B or Class C
returns  to the  return on  fixed-income  investments  available  from banks and
thrift   institutions.   Those  include   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.
Repayment of principal and payment of interest on Treasury  securities is backed
by the full faith and credit of the U.S. government.

      From time to time, the Fund may publish rankings or ratings of the Manager
or Transfer Agent, and of the investor services provided by them to shareholders
of the Oppenheimer  funds,  other than  performance  rankings of the Oppenheimer
funds themselves. Those ratings or rankings of shareholder and investor services
by third parties may include  comparisons of their services to those provided by
other mutual fund families selected by the rating or ranking services.  They may
be based upon the opinions of the rating or ranking  service  itself,  using its
research or judgment, or based upon surveys of investors,  brokers, shareholders
or others.


 ABOUT YOUR ACCOUNT

How to Buy Shares

Additional  information is presented below about the methods that can be used to
buy shares of the Fund.  Appendix C contains more information  about the special
sales charge  arrangements  offered by the Fund, and the  circumstances in which
sales charges may be reduced or waived for certain classes of investors.

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 ("ACH")
transfer to buy the shares.  Dividends will begin to accrue on shares  purchased
with 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. The proceeds of ACH  transfers  are normally
received by the Fund 3 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 Appendix C to this
Statement of Additional  Information because the Distributor or dealer or broker
incurs little or no selling expenses.

      |X| 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 for your  joint  accounts,  or for trust or  custodial  accounts  on
         behalf of your children who are minors, and
      |_|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, and
      |_|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.

     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.  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 reduced sales charge will apply only to current purchases. You must
request it when you buy shares.

      |X|   The  Oppenheimer  Funds.  The  Oppenheimer  funds are those mutual
funds  for   which   the   Distributor   acts  as  the   distributor   or  the
sub-distributor and currently include the following:

Centennial California Tax Exempt Trust  Centennial Tax Exempt Trust
Centennial Government Trust             Oppenheimer Cash Reserves
Centennial Money Market Trust           Oppenheimer Money Market Fund, Inc.

      There is an initial sales charge on the purchase of Class A shares of each
of  the  Oppenheimer  funds  except  the  money  market  funds.   Under  certain
circumstances described in this Statement of Additional Information,  redemption
proceeds of certain  money  market  fund  shares may be subject to a  contingent
deferred sales charge.

Letters 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.  You can include  purchases made up
to 90 days before the date of the Letter.

      A  Letter  of  Intent  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").  At the  investor's  request,  this  may  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 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.  However,  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. That amount is described in "Terms of
Escrow,"  below  (those  terms may be  amended by the  Distributor  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 a Letter of Intent. If those terms are amended,  as they may be from time to
time by the Fund,  the  investor  agrees to be bounded by the amended  terms and
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  Prospectus,  the sales
charges paid will be adjusted to the lower rate.  That  adjustment  will be made
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.

      |X|   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.  That sales charge  adjustment  will
apply to any shares  redeemed  prior to the  completion  of the  Letter.  If the
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 by exchange of either (1) Class
             A shares of one of the other  Oppenheimer  funds that were acquired
             subject to a Class A initial or contingent deferred sales charge or
             (2) 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 to buy shares  directly
from a bank  account,  you must  enclose a check  (minimum  $25) for the initial
purchase with your application.  Shares purchased by Asset Builder Plan payments
from bank  accounts  are  subject  to the  redemption  restrictions  for  recent
purchases  described  in  the  Prospectus.   Asset  Builder  Plans  also  enable
shareholders  of  Oppenheimer  Cash  Reserves to use their fund  account to make
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 Application. Neither
the  Distributor,  the Transfer Agent nor the Fund shall be responsible  for any
delays in purchasing shares resulting from delays in ACH transmissions.

      Before  initiating  Asset  Builder  payments,  obtain a prospectus  of the
selected  fund(s) from the Distributor or your financial  advisor and request an
application from the  Distributor,  complete it and return it. 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.  The  Transfer  Agent
requires a  reasonable  period  (approximately  15 days)  after  receipt of such
instructions to implement  them. The Fund reserves the right to amend,  suspend,
or discontinue offering Asset Builder 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.

Classes of Shares.  Each class of shares of the Fund  represents  an interest in
the same portfolio of investments of the Fund. However, each class has different
shareholder  privileges and features.  The net income attributable to Class B or
Class C shares and the  dividends  payable on Class B or Class C shares  will be
reduced by  incremental  expenses  borne  solely by that class.  Those  expenses
include the asset-based sales charges to which Class B and Class C are subject.

      The  availability of three classes of shares permits an investor to choose
the method of purchasing shares that is more appropriate for the investor.  That
may  depend  on the  amount of the  purchase,  the  length of time the  investor
expects  to hold  shares,  and  other  relevant  circumstances.  Class A  shares
normally are sold subject to an initial sales charge.  While Class B and Class C
shares have no initial  sales charge,  the purpose of the deferred  sales charge
and  asset-based  sales charge on Class B and Class C shares is the same as that
of the initial  sales charge on Class A shares - to compensate  the  Distributor
and brokers,  dealers and financial institutions that sell shares of the Fund. A
salesperson  who is  entitled to receive  compensation  for from his or her firm
selling Fund shares may receive different levels of compensation for selling one
class of shares than another.

      The  Distributor  will not accept any order in the amount of  $500,000  or
more for Class B shares or $1  million or more for Class C shares on behalf of a
single investor (not including dealer "street name" or omnibus  accounts).  That
is because  generally it will be more advantageous for that investor to purchase
Class A shares of the Fund.

      |X| Class B Conversion. 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.

      |X|  Allocation of Expenses.  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 shares,  and  therefore  are  indirectly  borne by  shareholders
through their investment.

      The  methodology  for  calculating  the net  asset  value,  dividends  and
distributions  of the Fund's  share  classes  recognizes  two types of expenses.
General expenses that do not pertain specifically to any one class are allocated
pro rata to the shares of all classes. The allocation is based on the percentage
of the Fund's total assets that is represented by the assets of each class,  and
then  equally to each  outstanding  share  within a given  class.  Such  general
expenses include  management fees, legal,  bookkeeping and audit fees,  printing
and mailing costs of shareholder reports, Prospectuses, Statements of Additional
Information and other materials for current  shareholders,  fees to unaffiliated
Trustees,  custodian expenses,  share issuance costs,  organization and start-up
costs, interest,  taxes and brokerage commissions,  and non-recurring  expenses,
such as litigation costs.

      Other expenses that are directly  attributable  to a particular  class are
allocated equally to each outstanding share within that class.  Examples of such
expenses  include  distribution  and service  plan  (12b-1)  fees,  transfer and
shareholder servicing agent fees and expenses,  and shareholder meeting expenses
(to the extent that such expenses pertain only to a specific class).

Determination  of Net Asset Values Per Share.  The net asset values per share of
each class of shares of the Fund are  determined  as of the close of business of
The New York Stock Exchange on each day that the Exchange is open. It is done 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 other 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 days on which the  Exchange  is closed  (including  weekends  and
holidays)  or after 4:00 P.M. on a regular  business  day.  The Fund's net asset
values will not be  calculated  on those days,  and the values of some of Fund's
portfolio  securities may change  significantly on those days, when shareholders
cannot purchase or redeem shares.

      |X|   Securities   Valuation.   The  Fund's   Board  of   Trustees   has
established procedures for the valuation of the Fund's securities.  In general
those procedures are as follows:

      |_| 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 Fund's  Board of
Trustees  or  obtained  by the  Manager  from two  active  market  makers in the
security on the basis of reasonable inquiry.

      |_| The following  securities are valued at the mean between the "bid" and
"asked" prices  determined by a pricing service  approved by the Fund's Board of
Trustees  or  obtained  by the  Manager  from two  active  market  makers in the
security on the basis of reasonable inquiry:

(4)   debt   instruments   that  have  a  maturity   of  more  than  397  days
         when-issued,

(5)      debt  instruments  that had a maturity of 397 days or less  when-issued
         and have a remaining maturity of more than 60 days, and

(6)      non-money  market debt  instruments  that had a maturity of 397 days or
         less  when-issued  and which have a  remaining  maturity  of 60 days or
         less.

         |_|      The following securities are valued at cost, adjusted
for amortization of premiums and accretion of discounts:

(3)      money market 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

(4)      debt  instruments  held by a money  market  fund that have a  remaining
         maturity of 397 days or less.

      |_| 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,  a  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).

      In the case of municipal  securities,  when last sale  information  is not
generally available,  the Manager may use pricing services approved by the Board
of Trustees.  The pricing service may use "matrix" comparisons to the prices for
comparable instruments on the basis of quality,  yield, maturity.  Other special
factors may be involved (such as the  tax-exempt  status of the interest paid by
municipal  securities).  The Manager  will  monitor the  accuracy of the pricing
services.  That  monitoring  may include  comparing  prices  used for  portfolio
valuation to actual sales prices of selected securities.

      Puts,  calls,  interest rate futures and municipal  bond index futures are
valued at the last sale 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, they shall
be valued at 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.  If not,  the 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 by
the mean  between  "bid" and "asked"  prices  obtained  by the Manager  from two
active  market  makers.  In certain  cases that may be at 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.  An
equivalent credit is included in the liability  section.  The credit is adjusted
("marked-to-market")  to reflect the  current  market  value of the  option.  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 premium paid by the Fund.

How to Sell Shares

The information  below supplements the terms and conditions for redeeming shares
set forth in the Prospectus.

Checkwriting.  When a check is presented to the Fund's 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 to receive  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  listed on the check or at the Fund's  custodian  bank.
That 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.

      In choosing to take advantage of the Checkwriting privilege by signing the
Account  Application or by completing a Checkwriting  card,  each individual who
signs:

(7)      for  individual  accounts,  represents  that  they  are the  registered
         owner(s) of the shares of the Fund in that account;

(8)      for accounts for corporations, partnerships, trusts and other entities,
         represents that they are an officer,  general partner, trustee or other
         fiduciary or agent, as applicable,  duly authorized to act on behalf of
         such registered owner(s);

(9)      authorizes  the Fund, its Transfer Agent and any bank through which the
         Fund's drafts  (checks) are payable to pay all checks drawn on the Fund
         account of such  person(s) and to redeem a sufficient  amount of shares
         from that account to cover payment of each check;

(10)     specifically  acknowledges  that if they choose to permit  checks to be
         honored if there is 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 the
         account,  even if that account is  registered in the names of more than
         one  person  or more  than  one  authorized  signature  appears  on the
         Checkwriting card or the Application, as applicable;

(11)     understands  that  the  Checkwriting  privilege  may be  terminated  or
         amended at any time by the Fund and/or the Fund's bank; and

(12)     acknowledges  and agrees that neither the Fund nor its bank shall incur
         any  liability  for  that  amendment  or  termination  of  checkwriting
         privileges or for redeeming shares to pay checks reasonably believed by
         them to be genuine, or for returning or not paying checks that have not
         been accepted for any reason.

Reinvestment Privilege.  Within six months of a redemption,  a shareholder may
reinvest all or part of the redemption proceeds of:

 |_|  Class A shares  purchased  subject to an initial  sales  charge or Class A
      shares on which a contingent deferred sales charge was paid, or

 |_|  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.  Reinvestment
will be at the net asset value next computed  after the Transfer  Agent receives
the  reinvestment  order.  The shareholder  must ask the Transfer Agent for that
privilege at the time of reinvestment.  This privilege does not apply to Class C
shares.  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.

      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.

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
Fund 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.

      The Fund has elected to be  governed  by Rule 18f-1  under the  Investment
Company Act.  Under that rule,  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 Fund will value  securities  used to pay redemptions in
kind  using the same  method  the Fund uses to value  its  portfolio  securities
described  above  under  "Determination  of Net Asset  Values Per  Share."  That
valuation will be made as of the time the redemption price is determined.

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 $200 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 such shares has fallen
below the stated minimum solely as a result of market fluctuations. If the Board
exercises  this  right,  it may also fix the  requirements  for any notice to be
given to the  shareholders  in question  (not less than 30 days).  The Board may
alternatively  set  requirements for the shareholder to increase the investment,
or set other terms and conditions so that the shares would not be  involuntarily
redeemed.

Transfers of Shares. A transfer of shares to a different  registration is not an
event that  triggers  the payment of sales  charges.  Therefore,  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.  It does not matter
whether the transfer occurs by absolute assignment,  gift or bequest, as long as
it does not involve,  directly or indirectly,  a public sale of the shares. When
shares  subject to a  contingent  deferred  sales  charge are  transferred,  the
transferred shares will remain subject to the contingent  deferred sales charge.
It  will  be  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 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.  Shareholders  should  contact  their
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.  However, 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, the Exchange closes at 4:00 P.M., but
may do so  earlier  on  some  days.  Additionally,  the  order  must  have  been
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.  The  signature(s)  of the  registered  owners  on the  redemption
documents must be guaranteed 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
(having  a  value  of at  least  $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.  Payments must also be sent to the address of record for
the account and the address must not have 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
Account Application or by signature-guaranteed instructions sent to the Transfer
Agent.  Shares are normally  redeemed  pursuant to an Automatic  Withdrawal Plan
three  business  days  before  the  payment  transmittal  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.  The
Fund reserves the right to amend, suspend or discontinue offering these 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 Appendix C below).

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

      |X|  Automatic  Exchange  Plans.  Shareholders  can authorize the Transfer
Agent 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.
Instructions  should  be  provided  on  the   OppenheimerFunds   Application  or
signature-guaranteed instructions.  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.

      |X| Automatic  Withdrawal Plans. Fund shares will be redeemed as necessary
to meet  withdrawal  payments.  Shares  acquired  without a sales charge will be
redeemed  first.  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
these plans should not be considered as a yield or income on your investment.

      The Transfer Agent will  administer the  investor's  Automatic  Withdrawal
Plan as agent for the  shareholder(s)  (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 not taken by the Transfer  Agent in good faith to administer the
Plan. Share 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.

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

      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 after 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 to redeem all, or any part of, the
shares held under the Plan.  That  notice  must be in proper form in  accordance
with the requirements of the then-current  Prospectus of the Fund. In that case,
the Transfer  Agent will redeem the number of shares  requested at the net asset
value  per  share  in  effect  and will  mail a check  for the  proceeds  to the
Planholder.

      The Planholder may terminate a Plan at any time by writing to the Transfer
Agent.  The Fund may also give  directions to the Transfer  Agent to terminate a
Plan. The Transfer Agent will also terminate a Plan upon its receipt of evidence
satisfactory  to it that the  Planholder  has died or is legally  incapacitated.
Upon  termination of a Plan by the Transfer Agent or the Fund,  shares that have
not  been  redeemed  will  be  held in  uncertificated  form in the  name of the
Planholder. The account will continue as a dividend-reinvestment, uncertificated
account unless and until proper  instructions  are received from the Planholder,
his or her executor or guardian, or another 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.  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 Oppenheimer funds that have a
single class  without a class  designation  are deemed "Class A" shares for this
purpose.  You can obtain a current list showing  which funds offer which classes
by calling the Distributor at 1-800-525-7048.

      |_| All of the  Oppenheimer  funds currently 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.

      |_| Oppenheimer  Main Street  California  Municipal Fund currently  offers
only 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.

      |_|   Class  Y  shares  of   Oppenheimer   Real   Asset   Fund  are  not
exchangeable.

      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.  They may also be used to
purchase  shares of  Oppenheimer  funds subject to a contingent  deferred  sales
charge.

      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 30 days 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.  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.  If  requested,  they must
supply proof of entitlement to this privilege.

      For accounts established on or before March 8, 1996 holding Class M shares
of Oppenheimer Convertible Securities Fund, Class M shares can be exchanged only
for Class A shares of other  Oppenheimer  funds.  Exchanges to Class M shares of
Oppenheimer  Convertible  Securities  Fund are permitted  from Class A shares of
Oppenheimer  Money Market Fund,  Inc. or  Oppenheimer  Cash  Reserves  that were
acquired by exchange of Class M shares.  No other exchanges may be made to Class
M shares.

      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.

      |X| How Exchanges Affect Contingent  Deferred Sales Charges. 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 18
months of the end of the calendar month of the initial purchase of the exchanged
Class A shares,  the Class A contingent  deferred sales charge is imposed on the
redeemed  shares.  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.  Before  exchanging
shares,  shareholders  should take into  account how the exchange may affect 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 which class of shares they wish to exchange.

      |X| Limits on Multiple  Exchange  Orders.  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.

      |_| Telephone  Exchange Requests.  When exchanging shares by telephone,  a
shareholder  must have an existing  account in the fund to which the exchange is
to be made.  Otherwise,  the  investors  must obtain a  Prospectus  of that fund
before the exchange request may be submitted.  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.

      |_| Processing  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 Fund may  refuse  the
request.

      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.

      The different  Oppenheimer  funds  available  for exchange have  different
investment objectives,  policies and risks. 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 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,  or as otherwise
described in "How to Buy Shares."  Daily  dividends will not be declared or paid
on newly purchased  shares until such time as 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 declared on
shares  repurchased  by a dealer or broker for three business days following the
trade  date (that is, up to and  including  the day prior to  settlement  of the
repurchase).  If all shares in an account are redeemed, all dividends accrued on
shares  of the  same  class  in the  account  will be  paid  together  with  the
redemption proceeds.

      The Fund's  practice of attempting to pay dividends on Class A shares at a
constant  level  requires  the Manager to monitor the Fund's  portfolio  and, if
necessary, to select higher-yielding securities when it is deemed appropriate to
seek income at the level  needed to meet the target.  Those  securities  must be
within  the  Fund's  investment  parameters,  however.  The Fund  expects to pay
dividends  at a  targeted  level  from  its  net  investment  income  and  other
distributable income without any impact on the net asset values per share.

      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.
Reinvestment  will be made 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.  Unclaimed  accounts may be subject to state  escheatment
laws, and the Fund and the Transfer Agent will not be liable to  shareholders or
their representatives for compliance with those laws in good faith.

      The amount of a distribution  paid on a class of shares 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.  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.  That is due to the  effect of the
asset-based  sales charge on Class B and Class C shares.  Those  dividends  will
also  differ in amount as a  consequence  of any  difference  in net asset value
among the different classes of shares.

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 that
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  that are free from Federal
income  taxes.  This  allocation  will  be  made  by the  use of one  designated
percentage  applied uniformly to all income dividends paid during the Fund's tax
year.  That  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. 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.

      A shareholder receiving a dividend from income earned by the Fund from one
or more of the  following  sources  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:

(4)       certain  taxable  temporary   investments  (such  as  certificates  of
          deposit,  repurchase  agreements,  commercial paper and obligations of
          the U.S. government, its agencies and instrumentalities);

(5)   income from securities loans; or


(6)       an excess of net  short-term  capital gain over net long-term  capital
          loss from the Fund.

      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.

      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.  That qualification  enables the Fund
to "pass through" its income and realized capital gains to shareholders  without
having to pay tax on them. 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  qualifies.  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  and will receive no tax  deduction for
payments of dividends and distributions made to shareholders.

      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. If it
does not, the Fund must pay an excise tax on the amounts not distributed.  It is
presently  anticipated that the Fund will meet those requirements.  However, the
Fund's Board of Trustees and the Manager  might  determine in a particular  year
that it would be in the best interest of shareholders 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 capital gains  distributions in shares of the same
class of any of the other Oppenheimer  funds listed above.  Reinvestment will be
made at net  asset  value  without  sales  charge.  To elect  this  option,  the
shareholder  must notify the Transfer Agent in writing and must have an existing
account in the fund selected for  reinvestment.  Otherwise the shareholder  must
first obtain a  prospectus  for that fund and an  application  from the Transfer
Agent 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/or  distributions  from certain of the
other  Oppenheimer  funds  may be  invested  in  shares of this Fund on the same
basis.

Additional Information About the Fund

The Distributor.  The Fund's shares are sold through dealers,  brokers and other
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  shares of the other  Oppenheimer
funds and is sub-distributor for funds managed by a subsidiary of the Manager.

The Transfer Agent.  OppenheimerFunds  Services, the Fund's Transfer Agent, is a
division  of  the  Manager.   It  is  responsible  for  maintaining  the  Fund's
shareholder  registry  and  shareholder   accounting  records,  and  for  paying
dividends  and  distributions  to  shareholders.  It  also  handles  shareholder
servicing and administrative  functions.  It acts on an "at-cost" basis. It also
acts  as  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 numbers shown on the back cover.

Custodian's  responsibilities  include  safeguarding  and controlling the Fund's
portfolio  securities  and handling the delivery of such  securities to and from
the Fund.  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.  Those
uninsured balances may at times be substantial.

Independent Auditors.  Deloitte & Touche LLP are the independent auditors of the
Fund. They audit 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.

================================================================================
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, 1998, the related statement of operations for the year then
ended, the statements of changes in net assets for the years ended September
30, 1998 and 1997, and the financial highlights for the period October 1, 1993,
to September 30, 1998. 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, 1998, 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, 1998, 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. 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 $13,215,710 or 9.79% of the
Fund's net assets as of September 30,1998.

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

As of September 30, 1998, securities subject to the alternative minimum tax
amount to $45,239,049 or 33.51% 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 a high level of current income exempt
from Federal income tax. 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 total assets in insured Municipal Securities. The Fund's investment
advisor is Oppenheimer Funds, 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.

- --------------------------------------------------------------------------------
Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated daily to
each class of shares based upon the relative proportion of net assets
represented by such class. Operating expenses directly attributable to a
specific class are charged against the operations of that class.

- --------------------------------------------------------------------------------
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.

<PAGE>
 
================================================================================

================================================================================
 
- --------------------------------------------------------------------------------
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.The character of the distributions made during the year from net
investment income or net realized gains may differ from its ultimate
characterization for federal income tax purposes. Also, due to timing of
dividend distributions, the fiscal year in which amounts are distributed may
differ from the fiscal year in which the income or realized gain was recorded by
the Fund.

   The Fund adjusts the classification of distributions to shareholders to
reflect the differences between financial statement amounts and distributions
determined in accordance with income tax regulations. Accordingly, during the
year ended September 30, 1998, amounts have been reclassified to reflect an
increase in paid-in capital of $420,762, a decrease in undistributed net
investment income of $415,198, and a decrease in accumulated net realized gain
on investments of $5,564.

- --------------------------------------------------------------------------------
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, in accordance with
federal income tax requirements.As of November 4, 1997, in order to conform book
and tax bases, the Fund began amortization of premiums on securities for book
purposes. Such cumulative change was limited to a reclassification adjustment
and had no impact on net assets or total increase (decrease) in net assets.
Accordingly, during the year ended September 30, 1998, amounts have been
reclassified to reflect an increase in net unrealized appreciation on
investments of $549,002. Paid-in capital was decreased by the same amount. 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
As of September 30, 1998, net unrealized appreciation on investments of
$10,115,877 was composed of gross appreciation of $10,115,877.

================================================================================
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 0.45% of the first
$100 million of average annual net assets, 0.40% of the next $150 million,
0.375% of the next $250 million and 0.35% of net assets in excess of $500
million. The Fund's management fee for the year ended September 30, 1998, was
0.44% of average annual net assets for its Class A, Class B and Class C shares.

  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, 1998, commissions (sales charges paid by
investors) on sales of Class A shares totaled $197,210, of which $47,360 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 $350,427 and $27,494, respectively, of which $5,664 and
$2,600, respectively, was paid to an affiliated broker/deal or Class B and Class
C shares. During the year ended September 30, 1998, OFDI received contingent
deferred sales charges of $80,736 and $1,564, 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 Oppenheimer funds.
OFS's total costs of providing such services are allocated ratably to these
funds.

   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 maintenance of accounts of their customers that hold Class
A shares. During the year ended September 30, 1998, OFDI paid $11,269 to an
affiliated broker/dealer as reimbursement for Class A personal service and
maintenance expenses.

   The Fund has adopted Distribution and Service Plans for Class B and Class C
shares to compensate OFDI for its costs in distributing Class B and Class C
shares and servicing accounts. Under the Plans, the Fund pays OFDI an annual
asset-based sales charge of 0.75% per year on Class B and Class C shares for its
services rendered in distributing Class B and Class C shares. OFDI also receives
a service fee of 0.25% per year to compensate dealers for providing personal
services for accounts that hold Class B and Class C shares. Each fee is
computed on the average annual net assets of Class B or Class C shares,
determined as of the close of each regular business day. During the year ended
September 30, 1998, OFDI paid $2,503 to an affiliated broker/dealer as
compensation for Class B personal service and maintenance expenses and retained
$197,544 and $25,438, 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. As of September 30, 1998, OFDI had
incurred excess distribution and servicing costs of $875,951 for Class B and
$67,456 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 Oppenheimer funds in an unsecured line of
credit with a bank, which permits borrowings up to $400 million, collectively.
Interest is charged to each fund, based on its borrowings, at a rate equal to
the Federal Funds Rate plus 0.35%. Borrowings are payable 30 days after such
loan is executed. The Fund also pays a commitment fee equal to its pro rata
share of the average unutilized amount of the credit facility at a rate of
0.0575% per annum.

   The Fund had no borrowings outstanding during the year ended September 30,
1998.

                       MUNICIPAL BOND RATINGS DEFINITIONS
- ------------------------------------------------------------------------------

Below are summaries of the rating definitions used by the  nationally-recognized
rating agencies listed below for municipal  securities.  Those ratings represent
the opinion of the agency as to the credit quality of issues that they rate. The
summaries below are based upon  publicly-available  information  provided by the
rating organizations.

Moody's Investors Service, Inc.
- ------------------------------------------------------------------------------

Long-Term Bond Ratings

Aaa: Bonds rated Aaa are judged to be the best quality.  They carry the smallest
degree of investment risk.  Interest  payments are protected by a large or by an
exceptionally   stable  margin  and  principal  is  secure.  While  the  various
protective  elements are likely to change,  the changes that can be expected are
most unlikely to impair the fundamentally strong position of such issues.

Aa: Bonds rated Aa are judged to be of high quality by all  standards.  Together
with the Aaa group,  they comprise what are generally known as high-grade bonds.
They are rated lower than the best bonds because  margins of protection  may not
be as large as with Aaa securities or fluctuation of protective  elements may be
of  greater  amplitude  or there may be other  elements  present  which make the
long-term risks appear somewhat larger than those of Aaa securities.

A: Bonds rated A possess  many  favorable  investment  attributes  and are to be
considered  as  upper-medium  grade  obligations.  Factors  giving  security  to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment sometime in the future.

Baa: Bonds rated Baa are considered medium grade obligations;  that is, 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 have  speculative
characteristics as well.

Ba: Bonds rated Ba are judged to have speculative elements.  Their future cannot
be  considered  well-assured.  Often the  protection  of interest and  principal
payments may be very moderate and not well safeguarded  during both good and bad
times over the  future.  Uncertainty  of  position  characterizes  bonds in this
class.

B:  Bonds  rated B  generally  lack  characteristics  of  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.

Caa:  Bonds rated Caa are of poor  standing and may be in default or there may
be present elements of danger with respect to principal or interest.

Ca:  Bonds rated Ca  represent  obligations  which are  speculative  in a high
degree and are often in default or have other marked shortcomings.

C: Bonds  rated C are the lowest  class of rated  bonds and can be  regarded  as
having extremely poor prospects of ever attaining any real investment standing.

Con. (...):  Bonds for which the security  depends on the completion of some act
or the  fulfillment of some condition are rated  conditionally.  These bonds are
secured by (a) earnings of projects under construction, (b) earnings of projects
unseasoned in operating  experience,  (c) rentals that begin when facilities are
completed,   or  (d)   payments  to  which  some  other   limitation   attaches.
Parenthetical   rating  denotes  probable  credit  stature  upon  completion  of
construction  or elimination of basis of condition.  Moody's  applies  numerical
modifiers 1, 2, and 3 in each generic rating classification from Aa through Caa.
The modifier "1" indicates  that the  obligation  ranks in the higher end of its
category;  the modifier "2"  indicates a mid-range  ranking and the modifier "3"
indicates a ranking in the lower end of the category.  Advanced  refunded issues
that are secured by certain assets are identified with a # symbol.

Short-Term Ratings - U.S. Tax-Exempt Municipals

There are four ratings  below for  short-term  obligations  that are  investment
grade.  Short-term speculative  obligations are designated SG. For variable rate
demand obligations,  a two-component rating is assigned. The first (MIG) element
represents  an  evaluation  by  Moody's of the  degree of risk  associated  with
scheduled  principal and interest  payments,  and the other (VMIG) represents an
evaluation of the degree of risk associated with the demand feature.

MIG 1/VMIG 1: Denotes best quality.  There is strong  protection by  established
cash flows, superior liquidity support or demonstrated broad-based access to the
market for refinancing..

MIG 2/VMIG 2: Denotes high quality. Margins of protection are ample although not
as large as in the preceding group.

MIG 3/VMIG 3: Denotes favorable quality. All security elements are accounted for
but there is lacking the undeniable strength of the preceding grades.  Liquidity
and cash flow  protection  may be narrow and market  access for  refinancing  is
likely to be less well established.

MIG 4/VMIG 4: Denotes adequate quality. Protection commonly regarded as required
of  an   investment   security  is  present  and  although  not   distinctly  or
predominantly speculative, there is specific risk.

SG:  Denotes  speculative  quality.  Debt  instruments  in this  category lack
margins of protection.

Standard & Poor's Rating Services
- ------------------------------------------------------------------------------

Long-Term Credit Ratings

AAA: Bonds rated "AAA" have the highest rating  assigned by Standard & Poor's.
The obligor's  capacity to meet its financial  commitment on the obligation is
extremely strong.

AA: Bonds rated "AA" differ from the highest rated  obligations  only in small
degree.  The  obligor's  capacity  to meet  its  financial  commitment  on the
obligation is very strong.

A: Bonds rated "A" are somewhat more  susceptible to adverse  effects of changes
in  circumstances  and economic  conditions  than  obligations  in  higher-rated
categories.  However, the obligor's capacity to meet its financial commitment on
the obligation is still strong.

BBB: Bonds rated BBB exhibit adequate protection  parameters.  However,  adverse
economic  conditions  or  changing  circumstances  are more  likely to lead to a
weakened  capacity  of the  obligor  to meet  its  financial  commitment  on the
obligation.

Bonds rated BB, B, CCC, CC and C are regarded as having significant  speculative
characteristics. BB indicates the least degree of speculation and C the highest.
While  such   obligations   will  likely  have  some   quality  and   protective
characteristics,  these  may be  outweighed  by  large  uncertainties  or  major
exposures to adverse conditions.

BB: Bonds rated BB are less  vulnerable  to  nonpayment  than other  speculative
issues. However, these face major uncertainties or exposure to adverse business,
financial,  or economic conditions which could lead to the obligor's  inadequate
capacity to meet its financial commitment on the obligation.

B: A bond rated B is more vulnerable to nonpayment than an obligation  rated BB,
but the obligor  currently has the capacity to meet its financial  commitment on
the obligation.

CCC: A bond rated CCC is currently  vulnerable to  nonpayment,  and is dependent
upon favorable business,  financial,  and economic conditions for the obligor to
meet its  financial  commitment  on the  obligation.  In the  event  of  adverse
business,  financial or economic  conditions,  the obligor is not likely to have
the capacity to meet its financial commitment on the obligation.

CC:  An obligation rated CC is currently highly vulnerable to nonpayment.

C: The C rating may used where a  bankruptcy  petition has been filed or similar
action has been taken, but payments on this obligation are being continued.

D: Bonds rated D are in  default.  Payments  on the  obligation  are not being
made on the date due.

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. The
"r" symbol is attached to the ratings of instruments with significant  noncredit
risks.

Short-Term Issue Credit Ratings

A-1: Rated in the highest category. The obligor's capacity to meet its financial
commitment on the obligation is strong.  Within this  category,  a plus (+) sign
designation  indicates the issuer's capacity to meet its financial obligation is
very strong.

A-2:  Obligation is somewhat more  susceptible to the adverse effects of changes
in  circumstances  and economic  conditions  than  obligations  in higher rating
categories.  However, the obligor's capacity to meet its financial commitment on
the obligation is satisfactory.

A-3:  Exhibits  adequate  protection  parameters.   However,   adverse  economic
conditions  or  changing  circumstances  are more  likely to lead to a  weakened
capacity of the obligor to meet its financial commitment on the obligation.

B:  Regarded  as having  significant  speculative  characteristics.  The obligor
currently has the capacity to meet its financial  commitment on the  obligation.
However, it faces major ongoing  uncertainties which could lead to the obligor's
inadequate capacity to meet its financial commitment on the obligation.

C:  Currently  vulnerable  to  nonpayment  and  is  dependent  upon  favorable
business,  financial,  and  economic  conditions  for the  obligor to meet its
financial commitment on the obligation.

D: In payment  default.  Payments on the obligation  have not been made on the
due date. The rating may also be used if a bankruptcy  petition has been filed
or similar actions jeopardize payments on the obligation.


Fitch IBCA, Inc.
- ------------------------------------------------------------------------------

International Long-Term Credit Ratings

Investment Grade:
AAA:  Highest Credit Quality.  "AAA" ratings denote the lowest  expectation of
credit  risk.  They  are  assigned  only in the case of  exceptionally  strong
capacity for timely payment of financial commitments.  This capacity is highly
unlikely to be adversely affected by foreseeable events.

AA: Very High Credit  Quality.  "AA" ratings denote a very low  expectation of
credit  risk.  They  indicate a very  strong  capacity  for timely  payment of
financial  commitments.  This  capacity  is not  significantly  vulnerable  to
foreseeable events.

A: High Credit  Quality.  "A" ratings denote a low expectation of credit risk.
The  capacity  for  timely  payment of  financial  commitments  is  considered
strong.  This capacity  may,  nevertheless,  be more  vulnerable to changes in
circumstances or in economic conditions than is the case for higher ratings.

BBB: Good Credit  Quality.  "BBB"  ratings  indicate that there is currently a
low  expectation  of credit risk. The capacity for timely payment of financial
commitments is considered  adequate,  but adverse changes in circumstances and
in economic  conditions are more likely to impair this  capacity.  This is the
lowest investment-grade category.

Speculative Grade:

BB:  Speculative.  "BB" ratings indicate that there is a possibility of credit
risk  developing,  particularly as the result of adverse  economic change over
time.  However,  business or financial  alternatives may be available to allow
financial commitments to be met.

B: Highly  Speculative.  "B" ratings indicate that significant  credit risk is
present,  but a limited margin of safety  remains.  Financial  commitments are
currently  being met.  However,  capacity for continued  payment is contingent
upon a sustained, favorable business and economic environment.

CCC, CC C: High  Default  Risk.  Default is a real  possibility.  Capacity for
meeting  financial  commitments  is solely reliant upon  sustained,  favorable
business or economic  developments.  A "CC" rating  indicates  that default of
some kind appears probable. "C" ratings signal imminent default.

DDD, DD, and D: Default.  Securities are not meeting  current  obligations and
are  extremely  speculative.   "DDD"  designates  the  highest  potential  for
recovery of amounts outstanding on any securities involved.

Plus (+) and  minus  (-)  signs  may be  appended  to a rating  symbol to denote
relative status within the rating  category.  Plus and minus signs are not added
to the "AAA" category or to categories below "CCC."

International Short-Term Credit Ratings

F1: Highest credit quality.  Strongest capacity for timely payment.  May have an
added "+" to denote exceptionally strong credit feature.

F2: Good credit quality.  A satisfactory  capacity for timely  payment,  but the
margin of safety is not as great as in higher ratings.

F3: Fair credit  quality.  Capacity  for timely  payment is  adequate.  However,
near-term adverse changes could result in a reduction to non-investment grade.

B:  Speculative.  Minimal capacity for timely payment,  plus  vulnerability to
near-term adverse changes in financial and economic conditions.

C:  High  default  risk.   Default  is  a  real   possibility,   Capacity  for
meeting  financial  commitments is solely reliant upon a sustained,  favorable
business and economic environment.

D:     Default. Denotes actual or imminent payment default.

Duff & Phelps Credit Rating Co. Ratings
- ------------------------------------------------------------------------------

Long-Term Debt and Preferred Stock

AAA:  Highest  credit  quality.  The risk factors are  negligible,  being only
slightly more than for risk-free U.S. 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 in periods of greater 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 likely to meet obligations when
due. Present or prospective  financial protection factors fluctuate according to
industry  conditions.  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 arrearages.

Short-Term Debt:

High Grade:
D-1+: Highest certainty of timely payment. Safety is just below risk-free
U.S. Treasury short-term debt.

D-1: Very high certainty of timely payment. Risk factors are minor.

D-1-: High certainty of timely payment. Risk factors are very small.

Good Grade:
D-2: Good certainty of timely payment. Risk factors are small.

Satisfactory Grade:
D-3:  Satisfactory  liquidity and other protection  factors qualify issues as to
investment grade. Risk factors are larger and subject to more variation.
Nevertheless, timely payment is expected.

Non-Investment Grade:
D-4: Speculative investment characteristics. Liquidity is not sufficient to
insure against disruption in debt service.

Default:
D-5: Issuer failed to meet scheduled principal and/or interest payments.

      In certain  cases,  the initial  sales charge that applies to purchases of
Class A shares of the Oppenheimer funds or the contingent  deferred sales charge
that may  apply to Class A,  Class B or Class C shares  may be  waived.  That is
because of the economies of sales  efforts  realized by the  Distributor  or the
dealers or other financial institutions offering those shares to certain classes
of investors or in certain transactions.

      Not all  waivers  apply to all funds.  For  example,  waivers  relating to
Retirement Plans do not apply to Oppenheimer  municipal funds, because shares of
those funds are not available for purchase by or on behalf of retirement  plans.
Other waivers apply only to  shareholders of certain funds that were merged into
or became Oppenheimer funds.

      For the  purposes  of  some  of the  waivers  described  below  and in the
Prospectus and Statement of Additional Information of the applicable Oppenheimer
funds,  the term  "Retirement  Plan" refers to the following types of plans: (7)
plans qualified under Sections 401(a) or 401(k) of the Internal
         Revenue Code,
(8) non-qualified  deferred compensation plans, (9) employee benefit plans1 (10)
Group  Retirement  Plans2 (11) 403(b)(7)  custodial plan accounts (12) SEP-IRAs,
SARSEPs or SIMPLE plans

         The  interpretation  of these  provisions as to the  applicability of a
waiver in a  particular  case is  determined  solely by the  Distributor  or the
Transfer  Agent of the fund.  These  waivers  and  special  arrangements  may be
amended or terminated at any time by the applicable Fund and/or the Distributor.
Waivers  that apply at the time shares are  redeemed  must be  requested  by the
shareholder and/or dealer in the redemption request.
- --------------
3. An "employee  benefit plan" means any plan or arrangement,  whether or not it
   is "qualified" under the Internal Revenue Code, under which Class A shares of
   an  Oppenheimer  fund  or  funds  are  purchased  by  a  fiduciary  or  other
   administrator  for the account of participants  who are employees of a single
   employer or of affiliated employers.  These may include, for example, medical
   savings accounts, payroll deduction plans or similar plans. The fund accounts
   must be registered in the name of the fiduciary or  administrator  purchasing
   the shares for the benefit of participants in the plan.
4. The term  "Group  Retirement  Plan"  means  any  qualified  or  non-qualified
   retirement  plan  for  employees  of a  corporation  or sole  proprietorship,
   members and  employees of a partnership  or  association  or other  organized
   group of persons  (the  members of which may include  other  groups),  if the
   group has made special  arrangements  with the Distributor and all members of
   the group  participating  in (or who are eligible to participate in) the plan
   purchase  Class A shares  of an  Oppenheimer  fund or funds  through a single
   investment dealer,  broker or other financial  institution  designated by the
   group.  Such plans  include 457 plans,  SEP-IRAs,  SARSEPs,  SIMPLE plans and
   403(b) plans other than plans for public  school  employees.  The term "Group
   Retirement Plan" also includes  qualified  retirement plans and non-qualified
   deferred  compensation  plans  and IRAs  that  purchase  Class A shares of an
   Oppenheimer fund or funds through a single investment dealer, broker or other
   financial institution that has made special arrangements with the Distributor
   enabling  those  plans to  purchase  Class A shares  at net  asset  value but
   subject to the Class A contingent deferred sales charge.

Applicability of Class A Contingent Deferred Sales Charges in Certain Cases
- ------------------------------------------------------------------------------

Purchases of Class A Shares of Oppenheimer Funds That Are Not Subject to Initial
Sales Charge but May Be Subject to the Class A Contingent  Deferred Sales Charge
(unless a waiver applies).

      There is no initial  sales charge on purchases of Class A shares of any of
the Oppenheimer funds in the cases listed below. However, these purchases may be
subject to the Class A contingent  deferred  sales charge if redeemed  within 18
months of the end of the calendar month of their  purchase,  as described in the
Prospectus (unless a waiver described  elsewhere in this Appendix applies to the
redemption).  Additionally,  on these  purchases  the  Distributor  will pay the
applicable  commission  described  in the  Prospectus  under "Class A Contingent
Deferred Sales Charge":
      |_|   Purchases of Class A shares aggregating $1 million or more.
o     Purchases by  a Retirement Plan that:
(4)   buys shares costing $500,000 or more, or
(5)   has,  at the time of  purchase,  100 or more  eligible  participants  or
            total plan assets of $500,000 or more, or
(6)         certifies  to the  Distributor  that it projects to have annual plan
            purchases of $200,000 or more.

         purchases are made:
(3)         through a broker, dealer, bank or registered investment adviser that
            has  made  special  arrangements  with  the  Distributor  for  those
            purchases, or
(4)         by a direct rollover of a distribution  from a qualified  Retirement
            Plan if the administrator of that Plan has made special arrangements
            with the Distributor for those purchases.
o        Purchases  of Class A shares by  Retirement  Plans that have any of the
         following record-keeping arrangements:
(4)   The record  keeping is performed by Merrill Lynch Pierce Fenner & Smith,
            Inc.  ("Merrill  Lynch")  on  a  daily  valuation  basis  for  the
            Retirement   Plan.   On  the  date  the  plan  sponsor  signs  the
            record-keeping  service  agreement  with Merrill  Lynch,  the Plan
            must have $3 million or more of its assets  invested in (a) mutual
            funds,  other than those advised or managed by Merrill Lynch Asset
            Management,  L.P.  ("MLAM"),  that  are  made  available  under  a
            Service  Agreement  between  Merrill  Lynch and the mutual  fund's
            principal  underwriter  or  distributor,  and (b) funds advised or
            managed by MLAM (the funds  described  in (a) and (b) are referred
            to as "Applicable Investments").
(5)   The record  keeping  for the  Retirement  Plan is  performed  on a daily
            valuation  basis by a record  keeper  whose  services are provided
            under a contract or arrangement  between the  Retirement  Plan and
            Merrill  Lynch.  On the date the plan  sponsor  signs  the  record
            keeping service  agreement with Merrill Lynch,  the Plan must have
            $3 million or more of its assets  (excluding  assets  invested  in
            money market funds) invested in Applicable Investments.
(6)         The record keeping for a Retirement  Plan is handled under a service
            agreement  with Merrill Lynch and on the date the plan sponsor signs
            that  agreement,  the Plan has 500 or more  eligible  employees  (as
            determined by the Merrill Lynch plan conversion manager).

      Oppenheimer Quest Value Fund, Inc., Oppenheimer Quest Balanced Value Fund,
      Oppenheimer  Quest  Opportunity  Value Fund,  Oppenheimer  Quest Small Cap

Distributor.

Account,  Connecticut  Mutual Growth  Account,  Connecticut  Mutual Total Return
Account,  CMIA LifeSpan Capital  Appreciation  Account,  CMIA LifeSpan  Balanced

Prior Class A CDSC and Class A Sales Charge Waivers

      |_| Class A Contingent  Deferred Sales Charge.  Certain  shareholders of a
Fund and the other Former  Connecticut  Mutual Funds are entitled to continue to
make additional purchases of Class A shares at net asset value without a Class A
initial  sales  charge,  but subject to the Class A  contingent  deferred  sales
charge that was in effect  prior to March 18,  1996 (the "prior  Class A CDSC").
Under the prior Class A CDSC,  if any of those  shares are  redeemed  within one
year of purchase, they will be assessed a 1% contingent deferred sales charge on
an amount equal to the current  market value or the original  purchase  price of
the shares  sold,  whichever  is smaller  (in such  redemptions,  any shares not
subject to the prior Class A CDSC will be redeemed first).

      Those  shareholders  who are  eligible for the prior Class A CDSC are: (3)
persons whose purchases of Class A shares of a Fund and other Former
         Connecticut  Mutual Funds were  $500,000  prior to March 18, 1996, as a
         result of direct purchases or purchases pursuant to the Fund's policies
         on Combined  Purchases or Rights of Accumulation,  who still hold those
         shares in that Fund or other Former Connecticut Mutual Funds, and
(4)      persons whose intended purchases under a Statement of Intention entered
         into prior to March 18, 1996,  with the former  general  distributor of
         the  Former  Connecticut  Mutual  Funds to  purchase  shares  valued at
         $500,000  or more over a  13-month  period  entitled  those  persons to
         purchase shares at net asset value without being subject to the Class A
         initial sales charge.

      Any of the  Class A shares  of a Fund  and the  other  Former  Connecticut
Mutual  Funds that were  purchased  at net asset value prior to March 18,  1996,
remain  subject  to the prior  Class A CDSC,  or if any  additional  shares  are
purchased by those  shareholders at net asset value pursuant to this arrangement
they will be subject to the prior Class A CDSC.

      |_| Class A Sales Charge Waivers.  Additional Class A shares of a Fund may
be purchased without a sales charge, by a person who was in one (or more) of the
categories  below and acquired Class A shares prior to March 18, 1996, and still
holds Class A shares:  (7) any  purchaser,  provided  the total  initial  amount
invested in the Fund
         or any one or more  of the  Former  Connecticut  Mutual  Funds  totaled
         $500,000 or more,  including  investments made pursuant to the Combined
         Purchases,  Statement of Intention and Rights of Accumulation  features
         available at the time of the initial  purchase and such  investment  is
         still held in one or more of the Former  Connecticut  Mutual Funds or a
         Fund into which such Fund merged;
(8)      any  participant in a qualified  plan,  provided that the total initial
         amount  invested  by the  plan  in the  Fund  or any one or more of the
         Former Connecticut Mutual Funds totaled $500,000 or more;
(9)      Directors  of the  Fund or any one or  more of the  Former  Connecticut
         Mutual Funds and members of their immediate families;
(10)     employee  benefit  plans  sponsored  by  Connecticut  Mutual  Financial
         Services,   L.L.C.  ("CMFS"),  the  prior  distributor  of  the  Former
         Connecticut Mutual Funds, and its affiliated companies;
(11)     one or more  members of a group of at least 1,000  persons (and persons
         who are  retirees  from  such  group)  engaged  in a  common  business,
         profession,  civic or charitable  endeavor or other  activity,  and the
         spouses and minor  dependent  children of such  persons,  pursuant to a
         marketing program between CMFS and such group; and
(12)     an  institution  acting as a fiduciary  on behalf of an  individual  or
         individuals,  if  such  institution  was  directly  compensated  by the
         individual(s)  for  recommending the purchase of the shares of the Fund
         or any one or more of the Former Connecticut Mutual Funds, provided the
         institution had an agreement with CMFS.

      Purchases  of Class A shares  made  pursuant  to (1) and (2)  above may be
subject to the Class A CDSC of the Former  Connecticut  Mutual  Funds  described
above.

      Additionally,  Class A shares of a Fund may be  purchased  without a sales
charge by any holder of a variable  annuity contract issued in New York State by
Connecticut  Mutual Life Insurance Company through the Panorama Separate Account
which is beyond the  applicable  surrender  charge  period and which was used to
fund a qualified plan, if that holder  exchanges the variable  annuity  contract
proceeds to buy Class A shares of the Fund.

above,  the contingent  deferred sales charge will be waived for  redemptions of
Class A and Class B shares of a Fund and  exchanges of Class A or Class B shares
of a Fund into  Class A or Class B shares of a Former  Connecticut  Mutual  Fund
provided  that  the  Class A or Class B shares  of the  Fund to be  redeemed  or
exchanged  were (i)  acquired  prior to March 18, 1996 or (ii) were  acquired by
exchange from an  Oppenheimer  fund that was a Former  Connecticut  Mutual Fund.
