ABOUT THE FUND

The Fund's Investment Objective and Strategies

WHAT IS THE  FUND'S  INVESTMENT  OBJECTIVE?  The  Fund  seeks as high a level of
current  interest  income  exempt from federal and  California  income taxes for
individual investors as is consistent with preservation of capital.

WHAT DOES THE FUND INVEST IN? The Fund invests  mainly in  California  municipal
securities  that pay  interest  exempt from  federal and  California  individual
income  taxes.  These  primarily  include  municipal  bonds (which are long-term
obligations),   municipal  notes  (short-term  obligations),  and  interests  in
municipal  leases.  Most of the  securities  the Fund buys  must be  "investment
grade" (the four highest  rating  categories of national  rating  organizations,
such as Moody's).

      The Fund does not limit its  investments  to  securities  of a  particular
maturity range, and may hold both short- and long-term  securities.  However, it
currently  focuses  on  longer-term  securities  to seek  higher  yields.  These
investments are more fully explained in "About the Fund's Investments," below.

How Does  The  Portfolio  Manager  Decide  What  Securities  To Buy Or Sell?  In
selecting  securities  for the  Fund,  the  portfolio  manager  looks  primarily
throughout  California for municipal securities using a variety of factors which
may change over time and may vary in particular  cases.  The  portfolio  manager
currently  looks for: o Securities  that  provide  high current  income o A wide
range of securities of different issuers within the state,
             including different agencies and municipalities, to spread risk
o     Securities having favorable credit characteristics
o     Special situations that provide opportunities for value

WHO IS THE FUND DESIGNED FOR? The Fund is designed for individual  investors who
are seeking  income exempt from federal and  California  income taxes.  The Fund
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 seeking capital growth. The Fund is not a complete investment program.

Main Risks of Investing in the Fund

      All  investments  have risks to some degree.  The Fund's  investments  are
subject to changes in their  value from a number of  factors,  described  below.
There is also the risk that poor  security  selection  by the Fund's  investment
Manager,  OppenheimerFunds,  Inc.,  will cause the Fund to under  perform  other
funds having a similar objective.

      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. There is no assurance that the Fund will achieve its objective.

HOW RISKY IS THE FUND OVERALL?  The value of the Fund's  investments 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. The Fund focuses its investments in California municipal securities and
is  non-diversified.  It will therefore be vulnerable to the effects of economic
changes that affect California  governmental  issuers.  These changes can affect
the  value  of  the  Fund's  investments  and  its  prices  per  share.  In  the
OppenheimerFunds  spectrum,  the Fund is more  conservative  than some  types of
taxable  bond funds,  such as high yield bond funds,  but has greater  risk than
money market funds.

      CREDIT RISK.  Municipal securities are subject to credit risk. Credit risk
is the risk that the issuer of a municipal  security might not 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 may be reduced.
Because the Fund can invest as much as 25% of its assets in municipal securities
below  investment  grade to seek  higher  income,  the Fund's  credit  risks are
greater than those of funds that buy only investment-grade bonds. A downgrade in
an  issuer's  credit  rating or other  adverse  news about an issue can reduce a
security's market value.

INTEREST RATE RISKS.  Municipal  securities are debt securities that are subject
to changes in value when prevailing  interest rates change.  When interest rates
fall, the values of already issued  municipal  securities  generally  rise. When
interest rates rise, the values of already issued 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.
The Fund  currently  focuses on longer term  securities  to seek higher  income.
Therefore, its share prices may fluctuate more when interest rates change.

RISKS OF  NON-DIVERSIFICATION.  The Fund is  "non-diversified."  That means that
compared to funds that are  diversified,  it can invest a greater portion of its
assets in the  securities  of one issuer,  such as bonds  issued by the State of
California.  Having a higher percentage of its assets invested in the securities
of fewer issuers,  particularly  obligations of government issuers of one state,
could result in greater fluctuations of the Fund's share prices due to economic,
regulatory or political problems in California.

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  variable  rate  obligations  are examples of
derivatives.

      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, may 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.  To try to
preserve  capital,  the Fund has  limits on the  amount of  particular  types of
derivatives it can hold.

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.


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 past ten calendar  years and by showing the average  annual
total  returns of the Fund's  shares and  comparing  the  returns of its Class A
shares to the returns of a market index. The Fund's past investment  performance
does not necessarily indicate how the Fund will perform in the future.

[See Bar Chart in Appendix to the Prospectus]

For  the  period  from  1/1/99  through  9/30/99,  the  cumulative  return  (not
annualized) for Class A shares was -3.65%. 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
8.65% (1Q'95) and the lowest return (not  annualized) for a calendar quarter was
- -6.00% (1Q'94).

The Fund's average annual total returns 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) and1% (5 years and
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. 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.
The  index  performance  does not  consider  the  effects  of  capital  gains or
transaction costs, and the Fund's investment may vary from 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 values
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 meant 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 July
31, 1999.

EXAMPLES.  The  following  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          1 year    3 years    5 years    10 years1
redeemed:
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------
Class A Shares         $563      $751       $955       $1,541
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------
Class B Shares         $670      $826       $1,107     $1,588
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------
Class C Shares         $270      $526       $907       $1,976
- ----------------------------------------------------------------------



- ----------------------------------------------------------------------
If shares are not      1 year    3 years    5 years    10 years1
redeemed:
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------
Class A Shares         $563      $751       $955       $1,541
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------
Class B Shares         $170      $526       $907       $1,588
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------
Class C Shares         $170      $526       $907       $1,976
- ----------------------------------------------------------------------
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 different types of investments  will vary over time based on the Manager's
evaluation of economic and market trend.  Under normal  market  conditions,  the
Fund:

o     attempts to invest 100% of its assets in municipal securities,

o     as a fundamental policy, invests at least 80% of its assets in municipal
        securities, and

o     invests at least 65% of its total assets in California municipal
        securities.

   The Manager  tries to reduce  risks by  selecting a wide variety of municipal
investments and by carefully  researching  securities before they are purchased.
However,  changes in the overall  market prices of municipal  securities and the
income  they pay can occur at any time.  The yield and share  prices of the Fund
will change daily based on changes in interest  rates and market  conditions and
in response to other economic  events.  The Statement of Additional  Information
contains  more detailed  information  about the Fund's  investment  policies and
risks.

MUNICIPAL  SECURITIES The Fund buys municipal  bonds and notes,  certificates of
participation in municipal leases and other debt obligations.

      The Fund  mainly  invest in  California  municipal  securities,  which are
municipal securities that are not subject (in the opinion of bond counsel to the
issuer at the time they are issued) to California  individual  income tax. These
debt  obligations  are  issued  by the  State of  California  and its  political
subdivisions (such as cities, towns,  counties,  agencies and authorities).  The
term "California  municipal  securities" may also include debt securities of the
governments of certain possessions,  territories and commonwealths of the United
States if the interest is not subject to California individual income tax.

      The  Fund  can  also  buy  other  municipal  securities,   issued  by  the
governments  of the  District of Columbia  and of other  states as well as their
political  subdivisions,  authorities and agencies, and 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).

      Municipal  securities are issued to raise money for a variety of public or
private  purposes,  including  financing state or local  governments,  financing
specific  projects or public  facilities.  The Fund can buy both  long-term  and
short-term  municipal  securities.  Long-term securities have a maturity of more
than one year. The Fund generally  focuses on  longer-term  securities,  to seek
higher income.

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

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 does not
invest more than 25% of its total  assets in municipal  securities  that are not
"investment  grade" at the time of purchase.  "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 rated
investment grade securities. Rating categories are described in the Statement of
Additional  Information.  A reduction in the rating of a security after the Fund
buys it 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.

      The  Manager  may rely 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 may also use its own research and analysis.  Many
factors affect an issuer's ability to make timely payments, and the credit risks
of a particular security may change over time.

Special Credit Risks of Lower-Grade Securities. Lower-grade municipal securities
may be subject to  greater  market  fluctuations  and  greater  risks of loss of
income and principal than higher-grade municipal securities. Securities that are
(or that have  fallen)  below  investment  grade  entail a greater risk that the
issuers may not meet their debt obligations.

Municipal  Lease  Obligations.  Municipal  leases  are used by state  and  local
government authorities to obtain funds to acquire land, equipment or facilities.
The  Fund  can  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.

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 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. An investment policy and technique is not fundamental unless
this Prospectus or the Statement of Additional Information says it is.

OTHER INVESTMENT  STRATEGIES.  To seek its objective,  the Fund can also use the
investment  techniques and strategies described below. The Fund might not always
use all of them.  These  techniques  involve risks although some are designed to
help reduce overall investment or market risks.

Floating Rate/Variable Rate Obligations. Some municipal securities 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.

      Certain variable rate bonds known as "inverse floaters" pay interest rates
that 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 cannot invest more than 20% of its total assets
in inverse floaters.

Other Derivatives.  The Fund can also invest in other derivative securities that
pay interest that depend on the change in value of an underlying asset, interest
rate or index. Examples are interest rate swaps,  municipal bond indices or swap
indices.

When-Issued and Delayed-Delivery  Transactions.  The Fund may purchase municipal
securities on a "when-issued"  basis and may purchase or sell such securities on
a "delayed-delivery"  basis. 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.

Puts and Stand-By  Commitments.  The Fund can acquire "stand-by  commitments" or
"puts" with respect to municipal securities.  The Fund obtains the right to sell
specified  securities at a set price on demand to the issuing  broker-dealer  or
bank. However, this feature may result in a lower interest rate on the security.
The Fund  acquires  stand-by  commitments  or puts  solely to enhance  portfolio
liquidity.

Illiquid and Restricted Securities.  Investments may be illiquid because they do
not have an active trading market,  making it difficult to value them or dispose
of them promptly at an acceptable  price. The Fund will not invest more than 15%
of its net assets in  illiquid  securities.  The  Manager  monitors  holdings of
illiquid  securities  on an  ongoing  basis  to  determine  whether  to sell any
holdings to maintain  adequate  liquidity.  The Fund cannot buy securities  that
have a restriction on resale.

Hedging.  The Fund can buy and sell futures contracts,  put and call options, 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.

      Hedging  involves  risk.  If the Manager uses a hedging  instrument at the
wrong time or judges 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.

Temporary  Defensive  Investments.  The Fund can  invest up to 100% of its total
assets in  temporary  defensive  investments  during  periods of unusual  market
conditions.  Generally,  they would be short-term municipal securities but could
be U.S.  Government  securities or highly-rated  corporate debt securities.  The
income from some temporary  defensive  investments  may not be  tax-exempt,  and
therefore  when  making  those  investments  the  Fund  might  not  achieve  its
objective.  The Fund can  also  hold  cash  and  cash  equivalents  pending  the
investment of proceeds  from the sale of Fund shares or portfolio  securities or
to meet anticipated redemptions of Fund shares.

How the Fund is Managed

THE MANAGER. The Fund's investment Manager, OppenheimerFunds,  Inc., selects the
Fund's investments and handles its day-to-day business.  The Manager carries out
its duties, subject to the policies established by the Board of Trustees,  under
an investment  advisory  agreement which states the Manager's  responsibilities.
The  agreement  sets the fees paid by the Fund to the Manager and  describes the
expenses that the Fund is responsible to pay to conduct its business.

      The Manager has operated as an investment  advisor since 1960. The Manager
(including  subsidiaries)  currently manages more than $110 billion of assets as
of  September  30,  1999,  including  other  Oppenheimer  funds with more than 5
million shareholder accounts.  The Manager is located at Two World Trade Center,
34th Floor, New York, New York 10048-0203.

Portfolio  Manager.  The portfolio  manager of the Fund is Christian D. Smith, a
Senior Vice President of the Manager.  He is the person principally  responsible
for the  day-to-day  management  of the Fund's  portfolio  and became the Fund's
portfolio manager on November 1, 1999. Mr. Smith is a Vice President of the Fund
and also serves as an officer and portfolio manager for other Oppenheimer funds.
Prior to joining  OppenheimerFunds  in  September  1999,  he was  Co-Head of the
Municipal Portfolio Management Team of Prudential Global Asset Management, prior
to which he was a portfolio manager for that firm (January 1990-January 1999).

Advisory  Fees.  Under  the  investment  advisory  agreement,  the Fund pays the
Manager an advisory  fee at an annual rate which  declines as the Fund's  assets
grow: 0.60% of the first $200 million of average annual net assets, 0.55% of the
next  $100  million,  0.50% of the next  $200  million,  0.45% of the next  $250
million,  0.40% of the next $250 million, and 0.35% of average annual net assets
over $1 billion.  The Fund's  management fee for its last fiscal year ended July
31, 1999, was 0.55% of average annual net assets for each class of shares.

YEAR 2000 ISSUES.  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 issuers may
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.

ABOUT YOUR ACCOUNT
- -------------------------------------------------------------------------------

How to Buy Shares

HOW DO YOU BUY SHARES?  You can buy shares several ways, as described below. The
Fund's  Distributor,  OppenheimerFunds  Distributor,  Inc., 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.

Buying  Shares  Through  Your  Dealer.  You can buy shares  through  any dealer,
broker,   or  financial   institution  that  has  a  sales  agreement  with  the
Distributor.  Your  dealer  will place your order with the  Distributor  on your
behalf.

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 your make a purchase to be sure that the Fund is appropriate  for
you.

o  Paying 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.

o     Buying Shares Through OppenheimerFunds AccountLink. With AccountLink,
   you pay for shares by electronic funds transfers from your bank account.
   Shares are purchased for your account by a transfer of money from your bank
   account through 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.

o  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.  You can make  additional  investments at any time with as
little as $25. There are reduced minimum  investments  under special  investment
plans.

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

o  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, which is
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.

o  Net Asset  Value.  The Fund  calculates  the net asset value of each class of
   shares  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.

The Offering  Price. 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.

Buying through a dealer.  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  Class A,  Class B or Class C shares.  If you do not
choose a class, your investment will be made in Class A shares.
- -------------------------------------------------------------------------------
- -------------------------------------------------------------------------------

- -------------------------------------------------------------------------------
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 You Buy Class A Shares?" below.

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.  If
you sell your shares within six years of buying them, you will normally pay a
contingent deferred sales charge.  That sales charge varies depending on how
long you own your  shares,  as  described  in "How Can You Buy Class B  Shares?"
below.
- -------------------------------------------------------------------------------

- -------------------------------------------------------------------------------
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. 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 You 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.

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.

o     Investing for the Shorter Term.  While the Fund is meant to be a
   long-term investment, 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.

o     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.

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 and checkwriting privileges 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.

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. To receive a waiver
or special sales charge rate, you must advise the  Distributor  when  purchasing
shares or the Transfer Agent when redeeming  shares that the special  conditions
apply.

HOW CAN YOU 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 a

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 0.50% 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 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 YOU REDUCE SALES  CHARGES IN BUYING CLASS A SHARES?  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.  The Class A initial and  contingent
deferred  sales  charges  are not  imposed  in the  circumstances  described  in
"Reduced Sales Charges" in the Statement of Additional Information.

HOW CAN YOU 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
net asset value.  The contingent  deferred sales charge is not imposed on: o the
amount of your account value represented by an increase in net asset
           value over the initial purchase price or
o     shares purchased by the reinvestment of dividends or capital gains
           distributions.
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 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:

- ----------------------------------------------------------------------
Years Since Beginning of     Contingent Deferred Sales Charge
Month in which Purchase      On Redemptions in That Year
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.

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 any  Class B shares  you hold
convert,  any  other  Class B shares  that  were  acquired  by  reinvesting  any
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 YOU 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: o 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 the Appendix
        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

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
compensate dealers,  brokers,  banks and other financial  institutions quarterly
for providing  personal  service and  maintenance of accounts of their customers
that hold Class A shares.

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 up to 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 ongoing  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 a 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  plans to pay the asset-based sales
charge as an ongoing  commission  to the dealer on Class C shares that have been
outstanding for a year or more.

ACCOUNT LINK. You can use our AccountLink feature to link your Fund account
with an account at a U.S. bank or other financial institution. It must be an
Automated Clearing House (ACH) member. AccountLink lets you:
o     transmit funds electronically to purchase shares by telephone (through a
             service representative or by PhoneLink) or automatically under
             Asset Builder Plans, or
o            have the  Transfer  Agent send  redemption  proceeds or to transmit
             dividends and distributions  directly to your bank account.  Please
             call the Transfer Agent for more information.

      You can  purchase  shares by  telephone  only after your  account has been
established.  To purchase  shares in amounts up to $250,000  through a telephone
representative,  call the Distributor at  1-800-852-8457.  The purchase  payment
will be debited from your bank account.

      AccountLink  privileges  should be requested on your  Application  or your
dealer's settlement  instructions if you buy your shares through a dealer. After
your account is established,  you can request AccountLink  privileges by sending
signature-guaranteed  instructions to the Transfer Agent. AccountLink privileges
will apply to each  shareholder  listed in the  registration  on your account as
well as to your dealer  representative  of record  unless and until the Transfer
Agent receives written  instructions  terminating or changing those  privileges.
After you establish  AccountLink  for your  account,  any change of bank account
information  must be made by  signature-guaranteed  instructions to the Transfer
Agent signed by all shareholders who own the account.

PHONELINK.  PhoneLink is the  OppenheimerFunds  automated  telephone system that
enables shareholders to perform a number of account  transactions  automatically
using a touch-tone  phone.  PhoneLink  may be used on  already-established  Fund
accounts after you obtain a Personal Identification Number (PIN), by calling the
special PhoneLink number, 1-800-533-3310.

Purchasing  Shares.  You may purchase shares in amounts up to $100,000 by phone,
by calling  1-800-533-3310.  You must have established AccountLink privileges to
link your bank account with the Fund to pay for these purchases.

Exchanging  Shares.  With the  OppenheimerFunds  Exchange  Privilege,  described
below, you can exchange shares  automatically by phone from your Fund account to
another  OppenheimerFunds  account you have already  established  by calling the
special PhoneLink number.

Selling Shares. You can redeem shares by telephone  automatically by calling the
PhoneLink  number  and  the  Fund  will  send  the  proceeds  directly  to  your
AccountLink  bank  account.  Please  refer to "How to Sell  Shares,"  below  for
details.

CAN YOU SUBMIT  TRANSACTION  REQUESTS BY FAX? You may send  requests for certain
types of account transactions to the Transfer Agent by fax (telecopier).  Please
call 1-800-525-7048 for information about which transactions may be handled this
way.  Transaction  requests  submitted  by fax are subject to the same rules and
restrictions as written and telephone requests described in this Prospectus.

OPPENHEIMERFUNDS  INTERNET WEB SITE. You can obtain  information about the Fund,
as well as your account balance, on the  OppenheimerFunds  Internet web site, at
http://www.oppenheimerfunds.com.   Additionally,   shareholders  listed  in  the
account  registration  (and the dealer of record)  may request  certain  account
transactions  through a special  section of that web site.  To  perform  account
transactions,  you must first obtain a personal  identification  number (PIN) by
calling  the  Transfer  Agent  at  1-800-533-3310.  If you do not  want  to have
Internet  account  transaction  capability  for your  account,  please  call the
Transfer Agent at 1-800-525-7048.

AUTOMATIC  WITHDRAWAL AND EXCHANGE PLANS. The Fund has several plans that enable
you to sell shares  automatically  or exchange them to another  Oppenheimer fund
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.

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):
      |_| You wish to redeem  more  than  $100,000  and  receive a check |_| The
      redemption check is not payable to all shareholders listed on
the account statement
      |_| The redemption check is not sent to the address of record on your
account statement
      |_| Shares are being transferred to a Fund account with a different
owner or name
      |_| Shares are being redeemed by someone (such as an Executor) other
than the owners

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

HOW DO YOU SELL SHARES BY MAIL?   Write a "letter of instructions" that
includes:
o     Your name
o     The Fund's name
o     Your Fund account number (from your account statement)
o     The dollar amount or number of shares to be redeemed
o     Any special payment instructions
o     Any share certificates for the shares you are selling
o     The signatures of all registered owners exactly as the account is
      registered, and
o     Any special  documents  requested by the Transfer  Agent to assure  proper
      authorization of the person asking to sell the shares.

HOW DO YOU SELL  SHARES BY  TELEPHONE?  You and your  dealer  representative  of
record may also sell your shares by telephone.  To receive the redemption  price
calculated on a particular  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. o To redeem shares through a
service representative,  call 1-800-852-8457 o To redeem shares automatically on
PhoneLink, call 1-800-533-3310

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

ARE THERE LIMITS ON AMOUNTS REDEEMED BY TELEPHONE?

Telephone Redemptions Paid by Check. Up to $100,000 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.

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.  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. o Checks can be written to the order of whomever you wish,
but may not be
   cashed at the bank the checks are payable through or the Fund's bank or the
   Custodian bank.
o  Checkwriting  privileges  are not available for accounts  holding shares that
   are subject to a contingent deferred sales charge.
o     Checks must be written for at least $100.
o  Checks  cannot be paid if they are written for more than your account  value.
   Remember,  your  shares  fluctuate  in value and you should not write a check
   close to the total account value.
o  You may not write a check that would  require the Fund to redeem  shares that
   were  purchased by check or Asset Builder Plan  payments  within the prior 10
   days.
o  Don't use your  checks if you changed  your Fund  account  number,  until you
   receive new checks.

Can You Sell Shares Through Your Dealer?  The Distributor has made  arrangements
to repurchase Fund shares from dealers and brokers on behalf of their customers.
Brokers or dealers may charge for that  service.  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: o Shares of the fund selected
for exchange must be available for sale in
   your state of residence.
o  The  prospectuses of this Fund and the fund whose shares you want to buy must
   offer the exchange privilege.
o  You must hold the shares you buy when you establish your account for at least
   7 days before you can exchange  them.  After the account is open 7 days,  you
   can exchange shares every regular business day.
o  You must meet the minimum purchase requirements for the fund whose shares you
   purchase by exchange.
o     Before exchanging into a fund, you must 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.

      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.

HOW DO I SUBMIT EXCHANGE REQUESTS? Exchanges may be requested in writing or
by telephone:

o  Written Exchange Requests.  Submit an OppenheimerFunds Exchange Request form,
   signed by all owners of the  account.  Send it to the  Transfer  Agent at the
   address on the Back Cover.

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

ARE THERE LIMITATIONS ON EXCHANGES? There are certain exchange policies you
should be aware of:
o     Shares are normally redeemed from one fund and purchased from the other
   fund in the exchange  transaction  on the same regular  business day on which
   the Transfer Agent receives an exchange request that 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.
o  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.
o  The Fund may amend,  suspend or terminate the exchange privilege at any time.
   Although  the  Fund  will  attempt  to  provide  you  notice  whenever  it is
   reasonably able to do so, it may impose these changes at any time.
o  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

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.

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.

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.

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.

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.

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 each class of shares.
The  redemption  value of your  shares may be more or less than  their  original
cost.

Payment for  redeemed  shares  ordinarily  is made in cash.  It is  forwarded by
check,  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.

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.

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.

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.

"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.

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 Taxes

DIVIDENDS. The Fund intends to declare dividends separately for Class A, Class B
and Class C 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.  Additionally, the amount of those dividends and the distributions
paid on class B and C shares may vary over time, depending on market conditions,
the  composition of the Fund's  portfolio,  and expenses borne by the particular
class of  shares.  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:

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.

Reinvest   Dividends  or  Capital   Gains.   You  can  elect  to  reinvest  some
distributions  (dividends,  short-term  capital gains or long-term capital gains
distributions)  in the Fund while receiving the other types of  distributions by
check or having them sent to your bank account through AccountLink.

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.

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  individual  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  paid  by  the  Fund  from  interest  on  California   municipal
securities  will be exempt from  California  individual  income taxes, if at the
close  of each  quarter  at least  50% of the  value of the  Fund's  assets  are
invested in debt obligations that pay interest exempt from California individual
income taxes.  Dividends paid from income from  municipal  securities of issuers
outside  California  will  normally be subject to California  individual  income
taxes.

      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,  and may be taxable at different rates depending on
how long the Fund  holds the  asset.  It does not  matter how long you have held
your  shares.  Dividends  paid from  short-term  capital  gains 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.

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.

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  income  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 KPMG 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., will
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 Fund does not make  investments  with the
objective of seeking capital growth,  since that would generally be inconsistent
with its goal of seeking tax-exempt income. However, the value of the securities
held by the Fund may be affected by changes in general  interest rates.  Because
the current value of debt securities varies inversely with changes in prevailing
interest rates, if interest rates increased after a security was purchased, that
security  would normally  decline in value.  Conversely,  should  interest rates
decrease after a security was purchased, normally its value would 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
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,  or
because of other factors affecting the issuer that cause the Manager to sell the
particular  security.  In that case, the Fund could experience 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.

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.

      Municipal  Bonds. We have classified  longer term municipal  securities 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,  if any,
power 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.

o 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.

o  Mello-Roos  Bonds.  These are bonds issued  under the  California  Mello-Roos
Community Facilities Act. They are used to finance infrastructure projects, such
as roads or sewage  treatment  plants.  In most cases  they are  secured by real
estate  taxes levied on property  located in the same  community as the project.
This type of  financing  was  created in response  to  statutory  limits on real
property taxes that were enacted in  California.  The bonds do not constitute an
obligation of a municipal  government.  Timely payment of principal and interest
depends on the ability of the developer of the project or other property  owners
to pay their real estate  taxes.  Therefore  these bonds are subject to risks of
nonpayment  as a result of a general  economic  decline  or  decline in the real
estate market, as well as the credit risk that of the developer.

o Private Activity  Municipal  Securities.  The Tax Reform Act of 1986 (the "Tax
Reform Act") reorganized,  as well as amended, the rules governing tax exemption
for  interest  on  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.

      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.

o       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.

o       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.

o       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.

o       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.

      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.

      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:

o     the frequency of trades and price quotations for such securities;

o     the number of dealers or other  potential  buyers  willing to purchase or
        sell such securities;

o     the availability of market-makers; and

o     the nature of the trades for such securities.

      While the Fund holds such  securities,  the Manager will also evaluate the
likelihood of a continuing market for these securities and their credit quality.

      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.

      Ratings of Municipal Securities.  Ratings by ratings organizations such as
Moody's Investors  Service,  Standard & Poor's  Corporation 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.

      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.

      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  may 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.

      A list of the rating  categories  of Moody's,  S&P and Fitch for municipal
securities  is  contained  in  Appendix  A  to  this   Statement  of  Additional
Information.  Because  the Fund may  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 assigning 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 Investing Primarily in California Municipal Securities. Because
the Fund focuses its investments  primarily on California municipal  securities,
the  value of its  portfolio  investments  will be  highly  sensitive  to events
affecting   the  fiscal   stability   of  the  State  of   California   and  its
municipalities,  authorities and other  instrumentalities that issue securities.
There have been a number of political  developments,  voter  initiatives,  state
constitutional amendments and legislation in California in recent years that may
affect the ability of the State  government  and  municipal  governments  to pay
interest and repay principal on the securities they have issued. In addition, in
recent years,  the State of California has derived a significant  portion of its
revenues from personal income and sales taxes. Because the amount collected from
these  taxes is  particularly  sensitive  to  economic  conditions,  the State's
revenues have been volatile.

      It is not  possible to predict the future  impact of the  legislation  and
economic considerations described below on the long-term ability of the State of
California or California municipal issuers to pay interest or repay principal on
their  obligations.  In part that is because of possible  inconsistencies in the
terms  of the  various  laws and  Propositions  and the  applicability  of other
statutes  to  these  issues.  The  budgets  of  California  counties  and  local
governments may be significantly affected by state budget decisions beyond their
control.  The information  below about these conditions is only a brief summary,
based upon  information  the Fund has drawn from  sources  that it believes  are
reliable.

      Changes to the State  Constitution.  Changes to the state  constitution in
recent  years have raised  general  concerns  about the ability of the State and
municipal  governments in California to obtain sufficient  revenues to pay their
bond  obligations.  In 1978,  California  voters  approved  Proposition  13,  an
amendment to the state constitution.  The Proposition added a new section to the
constitution  that limits ad valorem  taxes on real  property and  restricts the
ability of local  taxing  entities to increase  real  property  taxes.  However,
legislation  enacted after Proposition 13 provided help to California  municipal
issuers  to raise  revenue  to pay their  bond  obligations.  During  the severe
recession  California  experienced  from  1991 to 1993,  the  State  legislature
eliminated significant components of its aid to local governments. The State has
since increased aid to local  governments and reduced certain mandates for local
services.  Whether  legislation will be enacted in the future to either increase
or reduce the redistribution of State revenues to local governments,  or to make
them less  dependent on State budget  decisions,  cannot be  predicted.  Even if
legislation  increasing  such  distribution  is passed,  it cannot be  predicted
whether it will provide  sufficient  revenue for local municipal  issuers to pay
their bond obligations.

      Another  amendment  to the state  constitution  may also  have an  adverse
impact on state and municipal bond  obligations.  That  amendment  restricts the
state government from spending amounts in excess of appropriation limits imposed
on each state and local government  entity. If revenues exceed the appropriation
limit,  those  revenues  must be returned,  in the form of a revision in the tax
rates or fee schedules.

      Voter Initiatives. California voters have approved a number of initiatives
that affect the ability of the state and  municipalities  to finance  their bond
obligations.  In 1988, California voters approved Proposition 98, which requires
a minimum level of funding for public schools and community  colleges.  In 1986,
voters approved Proposition 62, which had a number of effects. One requires that
any special tax imposed by a local  government  must be approved by a two-thirds
vote of the  electorate.  In 1995,  the  California  Supreme  Court  upheld  the
constitutionality  of  that  Proposition.  That  created  uncertainty  as to the
legality of certain  local taxes  enacted by  non-charter  cities  without voter
approval. It is not possible to predict the eventual impact of that decision.

      In 1996,  California  voters  approved  Proposition  218. That  initiative
applied the provisions of Proposition 62 to all government  entities,  including
cities  having  charters.  It requires  that all taxes for  general  purposes be
approved by a simple  majority of the popular  vote,  and that taxes for special
purposes must be approved by a two-thirds  majority vote.  Proposition  218 also
limits  the   authority  of  local   governments   to  impose   property-related
assessments,  fees and charges.  It requires that such assessments be limited to
the special benefit  conferred and prohibits their use for general  governmental
services.  The  Proposition  enables  voters to use their  initiative  powers to
reduce or repeal previously-authorized taxes, assessments, fees and charges.

      Effect of other  State Laws on Bond  Obligations.  Some of the  tax-exempt
securities  that the Fund can invest in may be  obligations  payable solely from
the revenues of a specific institution or secured by specific properties.  These
are subject to  provisions  of California  law that could  adversely  affect the
holders of such obligations. For example, the revenues of California health care
institutions may be adversely  affected by State laws, and California law limits
the  remedies  of a  creditor  secured  by a  mortgage  or deed of trust on real
property.   Debt  obligations  payable  solely  from  revenues  of  health  care
institutions  may also be  insured  by the State but no  guarantee  exists  that
adequate  reserve funds will be appropriated  by the State  legislature for such
purpose.

      The Effect of General  Economic  Conditions in the State.  The  California
economy has been  recovering  from a general  economic  recession of a few years
ago. In 1997, the rate of growth in new jobs has been generally high compared to
the rest of the country. The unemployment rate, while relatively higher than the
national  average,  fell to an  average  of 5.9% in 1998,  compared  to over 10%
during the recessionary  period. Many of the new jobs were created in industries
such as computer services,  software design, motion pictures and high technology
manufacturing.  Business  services,  export trade and other  manufacturing  also
experienced  growth.  Recent economic  reports  indicate that, while the rate of
economic  growth in California  is expected to moderate over the next year,  the
increases  in  employment  and income may exceed those of the nation as a whole.
The unsettled financial situation occurring in certain Asian economies,  and its
spillover  effects  elsewhere,  may  continue  to  adversely  affect the State's
export-related industries and, therefore, the State's rate of economic growth.

      On June 29, 1999, the Governor of California  signed the 1999-2000  Budget
Act.  The Budget Act  estimated  General Fund  revenues  and  transfers of $63.0
billion and contained  expenditures  totaling $63.7 billion. The Budget Act also
contained  expenditures  of $16.1  billion from bond funds.  The  Administration
estimated a budget  reserve  balance at June 30,  2000,  of  approximately  $881
million. Not included in this amount was an additional $300 million which (after
the  Governor's  vetoes) was "set aside" to provide  funds for  employee  salary
increases  (to be  negotiated  in  bargaining  with  employee  unions),  and for
litigation  reserves.  The Budget Act  anticipates  normal  cash flow  borrowing
during the fiscal year.  Continued  State  economic  expansion and large revenue
increases  enabled the Governor and State  legislature  to provide  increases in
spending  programs in the 1999-2000  budget.  These included large  increases in
education and health and human services funding.

      In recent past years the state has  experienced  reductions in the overall
credit ratings assigned to its General  Obligation bonds by several major rating
agencies. In July 1994, the ratings of those bonds were downgraded from Aa to A1
by Moody's,  from A+ to A by Standard & Poor's and from AA to A by Fitch. At the
time, the rating  agencies all cited  uncertainty  about the State's  ability to
balance  its budget by 1996.  In 1996,  noting  improvements  in the  economy in
California  and the state budget,  both Fitch and Standard & Poor's raised their
ratings  of the  State's  General  Obligation  bonds from A to A+, in 1997 Fitch
raised its rating to AA-. In 1998 Moody's raised it's rating to Aa3, and in 1999
Standard & Poor's raised its rating to AA-.

      Special Financial Problems of Local Governments. Some local governments in
California have experienced notable financial difficulties. On December 6, 1994,
Orange County, California,  became the largest municipality in the United States
ever to have filed for  protection  under federal  bankruptcy  laws.  The filing
stemmed from losses of about $1.7 billion in the County's investment pool due to
investments  in high-risk  derivative  securities.  In September  1995 the state
legislature  approved  legislation  that  permitted  Orange  County  to use  for
bankruptcy  recovery  $820  million  in  sales  taxes  over 20 years  that  were
previously  earmarked for highways,  transit and  development.  In June 1996 the
County completed an $880 million bond offering secured by real property owned by
the County. On June 12, 1996, the County emerged from bankruptcy.  On January 7,
1997,  Orange County returned to the bond market with a $136 million bond issue.
In December  1997,  Moody's  raised its ratings on $325 million of Orange County
pension  obligation  bonds to Baa3 from Ba. In  February  1998,  Fitch  assigned
outstanding  Orange County pension  obligation bonds a BBB rating.  In September
1999, Moody's assigned the County an issuer (implied general  obligation) rating
of Aa3 and,  among other  things,  upgraded the ratings on the County's  pension
obligation bonds to A1.

      Los  Angeles  County,   the  nation's  most  populous  county,   has  also
experienced financial difficulties. Between 1992 and 1995 the County's long-term
bonds were  downgraded  three  times.  This  occurred as a result of a number of
factors,  including  severe  operating  deficits  for the  county's  health care
system.  In  addition,  the County was  affected by a long-term  loss of revenue
caused by state  property  tax  shift  initiatives  in 1993  through  1995.  The
County's  improving  financial  condition has been reflected in improved general
obligation  bond  ratings.  In  June  1999,  the Los  Angeles  County  Board  of
Supervisors  approved a budget of  approximately  $15 billion for 1999-2000,  up
from the $13.6  billion  approved  for the previous  fiscal  year.  The County's
financial  condition  will continue to be affected by the large number of County
residents who are dependent on government  services and by a structural  deficit
in its health department.

      Year 2000 Concerns.  In October 1997, the Governor of California issued an
executive order stating that solutions to the Year 2000 problem would be a state
government  priority.  Although the State reports that it is making  substantial
progress  overall  toward  the goal of Year  2000  compliance,  the task is very
complex and will likely  encounter  unexpected  difficulties.  The State has not
predicted  whether all mission  critical system will be ready and tested by late
1999 or what  impact  failure  of any  particular  IT  system(s)  or of  outside
interfaces  with State IT systems might have.  The State has indicated  that all
mission  critical  systems  will have a  contingency  business  plan in place to
mitigate potential system failures.

The State Treasurer's Office has reported that its systems for bond payments are
fully Y2K  compliant.  The State  Controller's  Office has reported  that it has
completed  the  necessary  Y2K  remediation  projects  for the State  fiscal and
accounting  system.  Both offices report they are actively  working with outside
entities with which they interface to ensure they are also compliant.  There can
be no assurance  that the steps taken by state or local  governments or agencies
to address the Year 2000 problem will be sufficient to avoid any adverse  impact
on their  budgets or  operations.  Therefore,  the possible  impact of Year 2000
problems on the debt securities  issued by those  governments and agencies,  and
which may be owned by the Fund, cannot be predicted with any certainty.

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.

      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 obligations.

      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 no 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.

      Inverse  Floaters and Other Derivative  Investments.  Inverse floaters may
offer relatively high current income,  reflecting the spread between  short-term
and long-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.

      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"  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.

      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.  Their  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 for its portfolio 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 to its custodian  bank cash,  U.S.  Government  securities or
other  high  grade  debt  obligations  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.

      Zero-Coupon Securities.  The Fund may buy zero-coupon and delayed interest
municipal  securities.  Zero-coupon  securities  do not make  periodic  interest
payments  and are sold at a deep  discount  from  their  face  value.  The buyer
recognizes  a rate of  return  determined  by the  gradual  appreciation  of the
security,  which is redeemed at face value on a specified  maturity  date.  This
discount  depends on the time remaining  until  maturity,  as well as prevailing
interest  rates,  the  liquidity of the  security and the credit  quality of the
issuer.  In the absence of threats to the issuer's credit quality,  the discount
typically decreases as the maturity date approaches. Some zero-coupon securities
are convertible,  in that they are zero-coupon  securities until a predetermined
date, at which time they convert to a security with a specified coupon rate.

      Because zero-coupon  securities pay no interest and compound semi-annually
at the rate fixed at the time of their  issuance,  their value is generally more
volatile  than the value of other  debt  securities.  Their  value may fall more
dramatically than the value of  interest-bearing  securities when interest rates
rise. When prevailing interest rates fall,  zero-coupon  securities tend to rise
more rapidly in value because they have a fixed rate of return.

      The Fund's  investment  in  zero-coupon  securities  may cause the Fund to
recognize income and make  distributions to shareholders  before it receives any
cash payments on the zero-coupon  investment.  To generate cash to satisfy those
distribution  requirements,  the Fund may have to sell portfolio securities that
it  otherwise  might  have  continued  to hold or to use cash  flows  from other
sources such as the sale of Fund shares.

      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.

      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.  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.  There is no limit on the amount
of the Fund's net assets that may be subject to  repurchase  agreements of seven
days or less.
      Repurchase  agreements,  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.  The  Manager  will  monitor  the  vendor's
creditworthiness  to  confirm  that the  vendor  is  financially  sound and will
continuously monitor the collateral's value.

      Illiquid  Securities.  The Fund has percentage  limitations  that apply to
purchases of illiquid  securities,  as stated in the Prospectus.  As a matter of
fundamental  policy, the Fund cannot purchase any securities that are subject to
restrictions on resale.

      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 are limited to not more
than 25% of the value of the Fund's total assets.  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 engage in loans of securities
that will exceed 5% of the value of the Fund's  total assets in the coming year.
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.

      Hedging.  The Fund may 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 may:

o sell interest rate futures or municipal bond index futures, o buy puts on such
futures or  securities,  or o write covered calls on  securities,  interest rate
futures or municipal
        bond index futures. Covered calls may also be written 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 may  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 will normally seek to purchase the securities,
and then terminate  that hedging  position.  For this type of hedging,  the Fund
may:

o     buy interest rate futures or municipal bond index futures, or
o     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
and are permissible under applicable regulations governing the Fund.

      Futures.  The Fund may 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").

      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.

      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  bank 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 bond resulting from a change in general  interest rates
(measured  by each 1%  change  in the rates on U.S.  Treasury  securities).  For
example,  if a bond has an effective  duration of three years,  a 1% increase in
general  interest  rates  would be  expected  to cause  the value of the bond to
decline 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 (in this case,  the duration of municipal  bonds  relative to
U.S. Treasury Bonds might have been greater than anticipated).

      Put and Call  Options.  The Fund  may buy and sell  certain  kinds of put
options (puts) and call options (calls). These strategies are described below.

      Writing  Covered  Call  Options.  The Fund may write (that is, sell) call
options. The Fund's call writing is subject to a number of restrictions:

(1)   After  the Fund  writes a call,  not more  than 25% of the  Fund's  total
        assets may be subject to calls.
(2)     Calls  the Fund  sells  must 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.
(3)     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.
(4)     The Fund may write calls on futures  contracts  that it owns,  but 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.

      The Fund's  custodian  bank,  or a  securities  depository  acting for the
custodian  bank,  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.

      Purchasing  Calls and Puts.  The Fund may buy  calls  only on  securities,
broadly-based municipal bond indices,  municipal bond index futures and interest
rate  futures.  It may 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.

      Calls on municipal bond indices,  interest rate futures and municipal bond
index  futures  are settled in cash rather  than by  delivering  the  underlying
investment.  Gain or loss depends on changes in the  securities  included in the
index in question  (and thus on price  movements in the debt  securities  market
generally) rather than on changes in price of the individual futures contract.

      The Fund may buy only those puts that relate to  securities  that the Fund
owns,  broadly-based  municipal  bond indices,  municipal  bond index futures or
interest rate futures  (whether or not the Fund owns the futures).  The Fund may
not sell puts other than puts it has previously purchased.

      When the Fund  purchases a put,  it pays a premium.  The Fund then has the
right to sell the underlying  investment to a seller of a  corresponding  put on
the same  investment  during the put period at a fixed exercise  price.  Puts on
municipal  bond  indices are settled in cash.  Buying a put on a debt  security,
interest rate future or municipal  bond index future the Fund owns enables it to
protect  itself  during  the put  period  against a decline  in the value of the
underlying  investment  below the  exercise  price.  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 lose its  premium  payment and the
right to sell the underlying  investment.  A put may be sold prior to expiration
(whether or not 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  may affect its portfolio  turnover rate and
brokerage  commissions.  The exercise of calls written by the Fund may cause the
Fund to sell related  portfolio  securities,  thus increasing its turnover rate.
The exercise by the Fund of puts on securities will cause the sale of underlying
investments,  increasing  portfolio  turnover.  Although the decision whether to
exercise a put it holds is within the Fund's control,  holding a put might cause
the Fund to sell the related investments for reasons that would not exist in the
absence of the put.

      The Fund may 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  may 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 may advance and the
value of debt  securities  held in the Fund's  portfolio  may  decline.  If that
occurred,  the  Fund  would  lose  money  on the  hedging  instruments  and also
experience a decline in value 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 may 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 may 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  may
decline.  If the Fund then concludes not to invest in such securities because of
concerns that there may 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.

      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 will enter into swap transactions with appropriate counterparties
pursuant to master netting agreements.  A master netting agreement provides that
all swaps done between the Fund and that counterparty under the master agreement
shall be regarded as parts of an integral agreement.  If on any date amounts are
payable 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  may 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.
The account must be a segregated account or accounts held by its custodian bank.

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

      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 the types of securities  it would buy for  temporary  defensive
purposes.

Investment Restrictions

      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: o 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
o     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.

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

o       The Fund cannot  invest in securities  or other  investments  other than
        municipal  securities,   the  temporary  investments  described  in  its
        Prospectus,  repurchase  agreements,  covered  calls,  private  activity
        municipal  securities  and hedging  instruments  described in "About the
        Fund" in the Prospectus or this Statement of Additional Information.

o       The Fund cannot  make  loans.  However,  repurchase  agreements  and the
        purchase  of  debt  securities  in  accordance  with  the  Fund's  other
        investment  policies and restrictions  are permitted.  The Fund may also
        lend its  portfolio  securities  as  described  in "Loans  of  Portfolio
        Securities."

o       The Fund cannot  borrow money in excess of 10% of the value of its total
        assets. It cannot buy any additional  investments when borrowings exceed
        5% of its  assets.  The Fund may borrow  only from banks as a  temporary
        measure for extraordinary or emergency purposes, and not for the purpose
        of leveraging its investments.

o       The Fund cannot  pledge,  mortgage or  otherwise  encumber,  transfer or
        assign its assets to secure a debt. However,  the use of escrow or other
        collateral  arrangements  in  connection  with  hedging  instruments  is
        permitted.

o       The Fund cannot  concentrate its investments to the extent of 25% of its
        total assets in any industry.  However, there is no limitation as to the
        Fund's  investments in municipal  securities in general or in California
        municipal  securities,  or in obligations issued by the U.S.  Government
        and its agencies or instrumentalities.

o       The Fund  cannot  invest  in real  estate.  This  restriction  shall not
        prevent  the  Fund  from  investing  in  municipal  securities  or other
        permitted  securities  that are secured by real estate or  interests  in
        real estate.

o       The Fund cannot purchase  securities  other than hedging  instruments on
        margin. However, the Fund may obtain such short-term credits that may be
        necessary for the clearance of purchases and sales of securities.
o     The Fund cannot sell securities short.

o       The Fund cannot  underwrite  securities or invest in securities that are
        subject to restrictions on resale.

o       The Fund cannot  invest in or hold  securities of any issuer if officers
        and Trustees of the Fund or the Manager  individually  beneficially  own
        more than 1/2 of 1% of the  securities  of that issuer and  together own
        more than 5% of the securities of that issuer.

o       The Fund cannot invest in securities  of any other  investment  company,
        except in connection with a merger with another investment company.

o       The Fund cannot buy or sell futures  contracts  other than interest rate
        futures and municipal bond index futures.

      The Fund  currently  has an operating  policy  (which is not a fundamental
policy but will not be changed without the approval of a shareholder  vote) that
prohibits the Fund from issuing senior securities.  However, the policy does not
prohibit  certain  activities  that are permitted by the Fund's other  policies,
including  borrowing  money for  emergency  purposes as  permitted  by its other
investment policies and applicable  regulations,  entering into delayed-delivery
and when-issued arrangements for portfolio securities transactions, and entering
into contracts to buy or sell derivatives, hedging instruments, options, futures
and the related margin,  collateral or escrow  arrangements  permitted under its
other investment 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.

Non-Diversification of the Fund's Investments.  The Fund is "non-diversified" as
defined  in  the  Investment  Company  Act.  Funds  that  are  diversified  have
restrictions against investing too much of their assets in the securities of any
one  "issuer."  That means  that the Fund can  invest  more of its assets in the
securities of a single issuer than a fund that is diversified.

      Being  non-diversified  poses additional  investment risks, because if the
Fund  invests  more of its assets in fewer  issuers,  the value of its shares is
subject to greater  fluctuations  from adverse  conditions  affecting any one of
those issuers. However, the Fund does limit its investments in the securities of
any one issuer to qualify for tax purposes as a "regulated  investment  company"
under the Internal Revenue Code. By qualifying,  it does not have to pay federal
income taxes if more than 90% of its earnings are  distributed to  shareholders.
To qualify, the Fund must meet a number of conditions.  First, not more than 25%
of the market value of the Fund's total assets may be invested in the securities
of a single issuer. Second, with respect to 50% of the market value of its total
assets,  (1) no more  than 5% of the  market  value of its total  assets  may be
invested in the  securities  of a single  issuer,  and (2) the Fund must not own
more than 10% of the outstanding voting securities of a single issuer.

      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 an  open-end,  diversified  management
investment  company with an unlimited number of authorized  shares of beneficial
interest. The Fund was organized as a Massachusetts business trust in July 1988.

      The Fund 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, and shareholders have the right
to call a meeting to remove a Trustee or to take other  action  described in the
Fund's Declaration of Trust.

      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:

      ohas its own dividends and distributions,
      opays certain  expenses which may be different for the different  classes,
      omay have a different net asset value, omay have separate voting rights on
      matters  in which  the  interests  of one  class  are  different  from the
      interests of another  class,  and ovotes as a class on matters that affect
      that class alone.

o Meetings of Shareholders.  As 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 the 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 its outstanding shares.
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 Fund's  shareholder  list
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 the
Fund  valued  at  $25,000  or more or  constituting  at least  1% of the  Fund's
outstanding  shares,  whichever is less. The Trustees may also take other action
as permitted by the Investment Company Act.

      Shareholder  and  Trustee  Liability.  The  Fund's  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 its 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.

Trustees  and Officers of the Fund.  The Fund's  Trustees and officers and their
principal  occupations and business affiliations and occupations during the past
five years are listed  below.  Trustees  denoted  with an asterisk (*) below are
deemed to be "interested  persons" of the Fund under the Investment Company Act.

1 Aggregate  compensation  includes  fees,  deferred  compensation,  if any, and
retirement plan benefits accrued for a Director.
2 For the 1998 calendar year.
3 Aggregate  compensation  from the Fund  reflect  fees from 1/1/98 to 10/31/98.
Total compensation for the 1998 calendar year includes compensation received for
serving as Trustee or Director of 11 other  Oppenheimer  funds.  4 Includes $345
deferred under Deferred Compensation Plan described below.

      Retirement Plan for Trustees.  The Fund has adopted a retirement plan that
provides for payments to retired Trustees. Payments are up to 80% of the average
compensation  paid during a Trustee's five years of service in which the highest
compensation  was  received.  A Trustee must serve as trustee for any of the New
York-based  Oppenheimer  funds  for at least 15  years  to be  eligible  for the
maximum payment. Each Trustee's retirement benefits will depend on the amount of
the Trustee's future compensation and length of service. Therefore the amount of
those benefits cannot be determined at this time, nor can we estimate the number
of years of credited service that will be used to determine those benefits.

      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.

      Major Shareholders.  As of October 15, 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 Class A, Class B or Class C shares were:

      Merrill  Lynch  Pierce  Fenner & Smith  Inc.,  4800 Deer Lake Drive  East,
      Jacksonville,  Florida  32246,  which  owned  744,986.922  Class B shares,
      representing  6.09% of the Class B shares then  outstanding,  for the sole
      benefit of its customers

      Merrill  Lynch  Pierce  Fenner & Smith  Inc.,  4800 Deer Lake Drive  East,
      Jacksonville,  Florida  32246,  which  owned  291,078.242  Class C shares,
      representing  19.26% of the Class C shares then outstanding,  for the sole
      benefit of its customers.

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.

      The portfolio  managers of the Fund are  principally  responsible  for the
day-to-day management of the Fund's investment  portfolio.  Other members of the
Manager's  fixed-income  portfolio  department,  particularly security analysts,
traders and other portfolio  managers have broad  experience  with  fixed-income
securities. They provide the Fund's portfolio managers with research and support
in managing the Fund's investments.

      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.  That  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.

      Expenses not expressly assumed by the Manager under the advisory agreement
are paid by the Fund.  The  investment  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 cost.
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.

           1999                $2,540,982
       -----------------------------------------------

      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 and to use the name  "Oppenheimer"  in connection with other
investment  companies  for which it may act as  investment  adviser  or  general
distributor.  If the Manager  shall no longer act as  investment  adviser to the
Fund, the Manager may withdraw the Fund's right 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. 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  has  permitted  the Manager to use  concessions  on
fixed-price offerings to obtain research, in the same manner as is permitted for
agency  transactions.  The Board has also  permitted  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 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.

      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.  If two or more of funds  advised  by the
Manager  purchase the same  security on the same day from the same  dealer,  the
Manager may average the price of the transactions and allocate the average among
the funds.

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 Fund's Class A, Class B and Class C shares.  The  Distributor is
not  obligated  to  sell  a  specific  number  of  shares.   Expenses   normally
attributable to sales are borne by the Distributor.  They exclude payments under
the  Distribution  and  Service  Plans but include  advertising  and the cost of
printing  and  mailing  prospectuses  (other  than those  furnished  to existing
shareholders).

      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:

1. The Distributor  advances commission payments to dealers for certain sales of
   Class A  shares  and for  sales of  Class B and  Class C shares  from its own
   resources  at the time of sale.  Because  Class B shares  convert  to Class A
   shares 72 months after purchase,  the "life-of-class" return for Class B uses
   Class A performance for the period after conversion.
2. Fiscal period of seven months.

      For  additional  information  about  distribution  of the  Fund's  shares,
including fees and expenses, please refer to "Distribution and Service Plans."

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,  cast in person at a
meeting called for the purpose of voting on that plan. The Manager cast the vote
to approve the Class C plan as the sole initial holder of Class C shares.

      Under the plans the  Manager  and the  Distributor  may make  payments  to
affiliates  and, in their sole  discretion,  from time to time may use their own
resources to make payments to brokers,  dealers or other financial  institutions
for  distribution  and  administrative  services  they perform at no cost to the
Fund.  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.  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 plans,  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.
Initially,  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.

      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 July 31, 1999, payments under the Plan for Class
A  shares  totaled  $757,647,  all of  which  was  paid  by the  Distributor  to
recipients.  That included $25,906 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.

      Class B and Class C Service and  Distribution  Plan Fees. 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  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: o pays sales commissions to authorized brokers and dealers
at the time of
        sale and pays service fees as described in the Prospectus,
o     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,
o     employs personnel to support distribution of shares, and
o     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.

      The  Distributor's  actual  expenses in selling Class B and Class C shares
may be more that the payments it receives  from the  contingent  deferred  sales
charges  collected  on  redeemed  shares and from the Fund  under the plans.  If
either  the  Class B or Class C 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 for distributing  shares before the plan was terminated.  The
Class B and Class C plans allow for the carry-forward of distribution  expenses,
to be recovered from asset based sales charges in subsequent fiscal periods.

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  during 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:

o       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.
o     The  Fund's  performance  returns do not  reflect  the effect of taxes or
        distributions.
o     An  investment  in the  Fund is not  insured  by the  FDIC  or any  other
        government agency.
o       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.
o       When an investor's  shares are redeemed,  they may be worth more or less
        than their original cost.
o       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.

      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:

- -------------------------------------------------------------------------------
                               [OBJECT OMITTED]
- -------------------------------------------------------------------------------
      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 and state taxable income
(the net amount  subject to federal and state  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.

      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:

                               [OBJECT OMITTED]
- -------------------------------------------------------------------------------
      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:

- -------------------------------------------------------------------------------
                               [OBJECT OMITTED]
- -------------------------------------------------------------------------------
      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.

      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 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 bond funds,  other than money market funds, and all general  municipal
bond 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.

      Morningstar  Ratings and Rankings.  From time to time the Fund may publish
the ranking  and/or star rating of the  performance  of its classes of shares by
Morningstar,  Inc., an independent mutual fund monitoring  service.  Morningstar
rates and ranks  mutual funds in broad  investment  categories:  domestic  stock
funds,  international stock funds,  taxable bond funds and municipal bond funds.
The Fund is included in the municipal bond category.

      Morningstar  proprietary  star ratings  reflect  historical  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 measured a fund's
(or class's)  performance  below 90-day U.S.  Treasury  bill  returns.  Risk and
investment  return are combined to produce star ratings  reflecting  performance
relative to the other funds 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 rating is the
fund's (or class's)  overall rating,  which is the fund's 3-year rating,  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 total return  ranking to that of other funds
in its Morningstar category, in addition to its star ratings. Those total return
ranking are percentages from one percent to one hundred percent and are not risk
adjusted. For example, if a fund is in the 94th percentile,  that means that 94%
of the funds in the same category performed better than it did.

      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.

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.

      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:
o     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
o       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
o       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.

      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:

Oppenheimer   California  Municipal

      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 public  offering  price
(including  the sales  charge)  that  applies to a single  lump-sum  purchase of
shares in the amount intended to be purchased under the Letter.

      In  submitting a Letter,  the  investor  makes no  commitment  to purchase
shares.  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.

      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  (the  minimum  is $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 are available
if your bank is an ACH member. Asset Builder Plans may not be used to buy shares
for OppenheimerFunds  employer-sponsored  qualified  retirement accounts.  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 debited  automatically.  Normally the debit will
be made two days prior to the investment dates you selected on your Application.
Neither the  Distributor,  the Transfer  Agent nor the Fund shall be responsible
for any delays in purchasing shares resulting from delays in ACH transmission.

      Before  you  establish  Asset  Builder  payments,   you  should  obtain  a
prospectus  of  the  selected  fund(s)  from  your  financial  advisor  (or  the
Distributor)  and request an  application  from the  Distributor.  Complete  the
application  and return  it.  You may  change  the amount of your Asset  Builder
payment or you can terminate these automatic  investments at any time by writing
to  the  Transfer  Agent.  The  Transfer  Agent  requires  a  reasonable  period
(approximately  10 days) after receipt of your  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 in
general 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 selling Fund shares may
receive  different  levels of  compensation  for  selling to one class of shares
rather 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.

      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.

      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,  share  registration  fees 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 U.S.
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 U.S.
holidays) or after 4:00 P.M. on a regular  business day.  Because the Fund's net
asset values will not be calculated  on those days,  the Fund's net asset values
per share may be significantly  affected on such days when  shareholders may not
purchase or redeem shares.

      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:

o       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.

o       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.
o       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.


o       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 :

o       Class A shares that you purchased  subject to an initial sales charge or
        Class A shares on which a contingent deferred sales charge was paid, or
o       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  liquid  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 "Waivers of Class B
and Class C Sales Charges" 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.

      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.

      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.


o  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.
o  Oppenheimer Main Street California Municipal Fund currently offers only Class
   A and Class B shares.
o  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.
o  Only certain Oppenheimer funds currently offer Class Y shares. Class Y shares
   of  Oppenheimer  Real Asset Fund may not be exchanged for shares of any other
   fund.
o  Class M shares of Oppenheimer  Convertible  Securities  Fund may be exchanged
   only for Class A shares of other Oppenheimer  funds. They may not be acquired
   by  exchange  of shares of any class of any other  Oppenheimer  funds  except
   Class A shares of Oppenheimer  Money Market Fund or Oppenheimer Cash Reserves
   acquired by exchange of Class M shares.
o  Class A shares of Senior  Floating Rate Fund are not available by exchange of
   Class A shares of other Oppenheimer  funds. Class A shares of Senior Floating
   Rate Fund that are  exchanged for shares of the other  Oppenheimer  funds may
   not be exchanged back for Class A shares of Senior Floating Rate Fund.
o  Class X shares of Limited Term New York  Municipal Fund can be exchanged only
   for Class B shares of other Oppenheimer funds and no exchanges may be made to
   Class X shares.
o  Shares of  Oppenheimer  Capital  Preservation  Fund may not be exchanged  for
   shares of Oppenheimer  Money Market Fund, Inc.,  Oppenheimer Cash Reserves or
   Oppenheimer  Limited-Term  Government  Fund.  Only  participants  in  certain
   retirement  plans may purchase  shares of  Oppenheimer  Capital  Preservation
   Fund, and only those  participants  may exchange shares of other  Oppenheimer
   funds for shares of Oppenheimer Capital Preservation Fund.

      Class A shares of  Oppenheimer  funds may be  exchanged at net asset value
for shares of any money  market fund offered by the  Distributor.  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
an early withdrawal charge or 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  sales charge 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.

      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.

      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  whether they intend to exchange  Class A, Class B or Class C
shares.

o 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.

o  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.

o  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 Class A, Class B and Class C 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;  (3) income or gains from options or futures;
or
(4)     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.

      In any year in which the Fund qualifies as a regulated  investment company
under the Internal  Revenue Code,  the Fund will also be exempt from  California
corporate income and franchise taxes. It will also be qualified under California
law to pay  exempt  interest  dividends  that  will be  exempt  from  California
personal  income  tax.  That  exemption  applies to the  extent  that the Fund's
distributions  are attributable to interest on California  municipal  securities
and qualifying  obligations of the United States government,  if at least 50% of
the Fund's assets are invested in such  obligations at the close of each quarter
in its tax year. Distributions from the Fund attributable to income from sources
other than California municipal securities and U.S. government  obligations will
generally be subject to California income tax as ordinary income.

      Distributions by the Fund from investment  income and long- and short-term
capital  gains  will  generally  not  be  excludable   from  taxable  income  in
determining  California  corporate  franchise  tax or income  tax for  corporate
shareholders of the Fund. Additionally,  certain distributions paid to corporate
shareholders  of the Fund may be includable in income  subject to the California
alternative minimum tax.

      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 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 bank of the Fund's assets.  The
custodian  bank'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
bank 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.  KPMG 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 California Municipal Fund:

We have audited the accompanying statement of assets and liabilities,  including
the statement of  investments,  of Oppenheimer  California  Municipal Fund as of
July 31, 1999, and the related  statement of operations for the year then ended,
the  statements  of changes in net assets for each of the years in the  two-year
period  then  ended and the  financial  highlights  for each of the years in the
three-year  period then ended,  the seven-month  period ended July 31, 1996, and
each of the  years  in the  two-year  period  ended  December  31,  1995.  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 as of July 31, 1999, by correspondence with the custodian and brokers; and
where  confirmations were not received from brokers, we performed other auditing
procedures.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.
               In our opinion, the financial statements and financial highlights
referred to above  present  fairly,  in all  material  respects,  the  financial
position of  Oppenheimer  California  Municipal  Fund as of July 31,  1999,  the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the  two-year  period  then  ended,  and the  financial
highlights  for each of the  years in the  three-year  period  then  ended,  the
seven-month  period ended July 31,  1996,  and each of the years in the two-year
period ended December 31, 1995, in conformity with generally accepted accounting
principles.

1. For zero coupon bonds,  the interest rate shown is the effective yield on the
date of purchase.  2.  Represents the current  interest rate for a variable rate
bond known as an "inverse  floaters"  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
$46,972,545  or  10.08%  of the  Fund's  net  assets  as of July  31,  1999.  3.
When-issued  security  to be  delivered  and  settled  after July 31,  1999.  4.

collateralized  accounts to cover initial  margin  requirements  on open futures
sales contracts. See Note 5 of Notes to Financial Statements.  5. Represents the
current  interest rate for a variable rate  security.  6. Denotes a step bond: a

================================================================================
1. Significant Accounting Policies
Oppenheimer California Municipal Fund (the Fund) is registered under the
Investment Company Act of 1940, as amended, as a non-diversified, open-end
management investment company. The Fund's investment objective is to seek as
high a level of current interest income exempt from federal and California
income taxes for individual investors as is consistent with preservation of
capital. 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, on investments up to $1 million. Class B and
Class C shares may be subject to a contingent deferred sales charge (CDSC). All
classes of shares have identical rights to earnings, assets and voting
privileges, except that each class has its own expenses directly attributable to
that class and exclusive voting rights with respect to matters affecting that
class. Classes A, B and C have separate distribution and/or service plans. 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.
- --------------------------------------------------------------------------------
Securities  Valuation.  Portfolio  securities are valued at the close of the New
York Stock  Exchange on each trading day.  Listed and  unlisted  securities  for
which such  information is regularly  reported are valued at the last sale price
of the day or, in the  absence of sales,  at values  based on the closing bid or
the  last  sale  price  on the  prior  trading  day.  Long-term  and  short-term
"non-money  market" debt  securities are valued by a portfolio  pricing  service
approved by the Board of Trustees.  Such securities which cannot be valued by an
approved portfolio pricing service are valued using  dealer-supplied  valuations
provided the Manager is satisfied that the firm rendering the quotes is reliable
and  that  the  quotes  reflect  current  market  value,  or  are  valued  under
consistently  applied  procedures  established  by  the  Board  of  Trustees  to
determine  fair  value  in good  faith.  Short-term  "money  market  type"  debt
securities having a remaining maturity of 60 days or less are valued at cost (or
last  determined  market  value)  adjusted for  amortization  to maturity of any
premium or  discount.  Options are valued  based upon the last sale price on the
principal  exchange  on which the  option is traded  or, in the  absence  of any
transactions  that day, the value is based upon the last sale price on the prior
trading  date if it is within  the  spread  between  the  closing  bid and asked
prices. If the last sale price is outside the spread, the closing bid is used.

================================================================================
Securities Purchased on a When-Issued Basis. Delivery and payment for securities
that have been purchased by the Fund on a forward commitment or when-issued
basis can take place a month or more after the transaction date. Normally the
settlement date occurs within six months after the transaction date; however,
the fund may, from time to time, purchase securities whose settlement date
extends beyond six months and possibly as long as two years or more beyond the
trade date. During this period, such securities do not earn interest, are
subject to market fluctuation and may increase or decrease in value prior to
their delivery. The Fund maintains segregated assets with a market value equal
to or greater than the amount of its purchase commitments. The purchase of
securities on a when-issued or forward commitment basis may increase the
volatility of the Fund's net asset value to the extent the Fund makes such
purchases while remaining substantially fully invested. As of July 31, 1999, the
Fund  had  entered  into  outstanding  when-issued  or  forward  commitments  of
$4,107,525.
- --------------------------------------------------------------------------------
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. As of July 31, 1999, the
Fund had available for federal tax purposes an unused  capital loss carryover of
approximately $650,000, which expires in 2006.
- -------------------------------------------------------------------------------
Trustees' Compensation. The Fund has adopted a nonfunded retirement plan for the
Fund's  independent  Trustees.  Benefits  are based on years of service and fees
paid to each trustee during the years of service. During the year ended July 31,
1999,  a  provision  of  $2,209  was  made  for  the  Fund's  projected  benefit
obligations and payments of $6,365 were made to retired  trustees,  resulting in
an accumulated liability of $159,162 as of July 31, 1999.
               The Board of Trustees  has adopted a deferred  compensation  plan
for independent  Trustees that enables Trustees to elect to defer receipt of all
or a portion of annual  compensation they are entitled to receive from the Fund.
Under the plan, the compensation  deferred is periodically adjusted as though an
equivalent  amount had been  invested  for the Trustees 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 affect the net assets of the
Fund,  and will not  materially  affect the Fund's  assets,  liabilities  or net
income per share.

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


================================================================================
1. Significant Accounting Policies  (continued)
Dividends and Distributions to Shareholders. Dividends and distributions to
shareholders,  which are determined in accordance  with income tax  regulations,
are recorded on the ex-dividend date.
- --------------------------------------------------------------------------------
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 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.
- --------------------------------------------------------------------------------
Expense Offset Arrangements. Expenses paid indirectly represent a reduction of
custodian fees for earnings on cash balances maintained by the Fund.
- --------------------------------------------------------------------------------
Other.  Investment  transactions  are accounted  for as of trade date.  Original
issue  discount is accreted and premium is amortized in accordance  with federal
income tax  requirements.  For municipal 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.
               There are certain risks arising from geographic  concentration in
any  state.  Certain  revenue  or tax  related  events in a state may impair the
ability of certain issuers of municipal securities to pay principal and interest
on their obligations.
               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.

================================================================================
Class A Service  Plan  Fees.  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. The Class A service plan permits reimbursements to
the Distributor at a rate of up to 0.25% of average annual net assets of Class A
shares. The Distributor makes payments to plan recipients quarterly at an annual
rate not to exceed 0.25% of the average annual net assets  consisting of Class A
shares of the Fund. For the fiscal year ended July 31, 1999,  payments under the
Class A Plan  totaled  $757,647,  all of which  was paid by the  Distributor  to
recipients.  That  included  $25,906 paid to an  affiliate of the  Distributor's
parent company. Any unreimbursed expenses the Distributor incurs with respect to
Class A shares in any fiscal year cannot be recovered in subsequent years.
- --------------------------------------------------------------------------------
Class B and Class C Distribution and Service Plan Fees. 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 plan during the period for which the fee is paid.
               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.  The asset-based sales charges
on Class B and Class C shares allow  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 the  contingent  deferred
sales charges collected on redeemed shares and from the Fund under the plans. If
either the Class B or the Class C 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 for distributing  shares before the plan was terminated.  The
plans allow for the carry-forward of distribution expenses, to be recovered from
asset-based sales charges in subsequent fiscal periods.

Distribution fees paid to the Distributor for the year ended July 31, 1999, were
as follows:

5. Futures Contracts
The Fund may buy and sell futures  contracts in order to gain  exposure to or to
seek to 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 may  recognize  a  realized  gain or loss when the
contract is closed or expires.
               Securities  held in  collateralized  accounts  to  cover  initial
margin  requirements  on open futures  contracts  are noted in the  Statement of
Investments.  The  Statement  of Assets and  Liabilities  reflects a  receivable
and/or payable for the daily mark to market for variation margin.
               Risks of entering into futures  contracts  (and related  options)
include the  possibility  that there may be an illiquid market and that a change
in the value of the  contract or option may not  correlate  with  changes in the
value of the underlying securities.

As of July 31, 1999, the Fund had outstanding futures contracts as follows:

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 July

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

Municipal Bonds

Moody's Investor Services,  Inc. The ratings of Moody's Investors Service,  Inc.
("Moody's") for municipal bonds are Aaa, Aa, A, Baa, Ba, B, Caa, Ca and C. Those
bonds in the Aa, A, Baa,  Ba and B groups  which  Moody's  believes  possess the
strongest  investment  attributes  are  designated  Aa1,  A1,  Baa1,  Ba1 and B1
respectively.

|_| Aaa. Municipal bonds rated "Aaa" are judged to be of the "best quality." |_|
Aa. The rating "Aa" is  assigned  to bonds which are judged of "high  quality by
all  standards,"  but as to which margins of  protection or other  elements make
long-term risks appear somewhat larger than "Aaa" rated municipal  bonds.  "Aaa"
and "Aa" rated bonds are generally known as "high grade bonds." |_| A. Municipal
bonds rated "A" by Moody's possess many favorable investment  attributes and are
considered  "upper  medium  grade  obligations."   Factors  giving  security  to
principal and interest of A rated bonds are  considered  adequate,  but elements
may be present which suggest a susceptibility  to impairment at some time in the
future.  |_| Baa.  Municipal  bonds rated "Baa" are  considered  "medium  grade"
obligations.  They are neither  highly  protected nor poorly  secured.  Interest
payments  and  principal  security  appear  adequate for the present but certain
protective elements may be lacking or may be characteristically  unreliable over
any  great   length  of  time.   These   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  as well  assured.  Often the  protection  of interest and  principal
payments may be very moderate and thereby not well safeguarded  during both good
and bad times over the future.  Uncertainty of position  characterizes  bonds in
this  class.  |_| B.  Bonds  rated "B"  generally  lack  characteristics  of the
desirable  investment.  Assurance  of  interest  and  principal  payments  or of
maintenance  of other terms of the contract  over any long period of time may be
small.  |_| Caa. Bonds rated "Caa" are in poor  standing.  Such issues 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.  Such  issues  are  often in  default  or have  other  marked
shortcomings. |_| C. Bonds rated "C" are the lowest rated class of bonds. Issues
so rated can be regarded as having  extremely  poor  prospects of ever attaining
any real investment standing.

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


Standard & Poor's Corporation.  Bonds rated in the top four categories (AAA, AA,
A, BBB) are commonly  referred to as "investment  grade." 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.  Ratings of BB, B, CCC and CC are
regarded as having significant speculative characteristics.

|_| AAA.  Obligors of municipal bonds rated AAA have "extremely strong capacity"
to meet financial  commitments.  |_| AA. The rating AA is given to obligors with
"very strong  capacity" to meet  financial  commitments.  |_| A. The rating A is
given to obligors with a "strong capacity" to meet financial  commitments but is
somewhat more  susceptible to adverse  effects of changes in  circumstances  and
economic conditions than obligors in higher categories.  |_| BBB. The BBB rating
is given  to an  obligor  that has  "adequate  capacity"  to meet its  financial
commitments.  However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened  capacity of the obligor to meet its financial
commitments. |_| BB. Obligors rated BB are less vulnerable in the near-term than
other lower-rated obligations to default than other speculative issues. However,
they  face  major  ongoing   uncertainties  or  exposure  to  adverse  business,
financial,  or economic  conditions  which would lead to inadequate  capacity to
meet financial commitments. |_| B. Obligors rated B have a greater vulnerability
than  obligors  rated BB, but  currently  has the capacity to meet its financial
commitments.  Adverse business,  financial,  or economic  conditions will likely
impair the obligor's capacity or willingness to meet its financial  commitments.
|_| CCC.  Obligors  rated CCC are currently  vulnerable  and are dependent  upon
favorable  business,  financial,  and  economic  conditions  to  meet  financial
commitments.  |_| CC. Obligors rated CC are currently highly vulnerable.  |_| C.
Bonds rated C typically are debt subordinated to senior debt that is assigned an
actual  or  implied  CCC-  debt  rating.  The C  rating  may be used to  cover a
situation where a bankruptcy  petition has been filed, but debt service payments
are  continued.  |_| D.  Bonds  rated D are in  payment  default.  The D  rating
category is used when  interest  payments or principal  payments are not made on
the date due even if the  applicable  grace period has not  expired,  unless S&P
believes that such  payments will be made during the grace period.  The D rating
also  will be used upon the  filing of a  bankruptcy  petition  if debt  service
payments are  jeopardized.  Fitch. The ratings of Fitch IBCA, Inc. for municipal
bonds are AAA,  AA, A, BBB,  BB, B, CCC, CC, C, DDD, DD, and D. Bonds rated AAA,
AA, A and BBB are  considered to be of  investment  grade  quality.  Bonds rated
below BBB are considered to be of speculative  quality. |_| AAA. Municipal Bonds
rated AAA are judged to be of the "highest  credit  quality." |_| AA. The rating
of AA is assigned to bonds of "very high credit quality." |_| A. Municipal bonds
rated A are  considered to be of "high credit  quality." |_| BBB. The rating BBB
is assigned to bonds of "satisfactory credit quality." A and BBB rated bonds are
more vulnerable to adverse changes in economic conditions than bonds with higher
ratings.  |_|  BB.  The  rating  BB  is  assigned  to  bonds  considered  to  be
"speculative." |_| B. The rating B is assigned to bonds considered to be "highly
speculative." |_| CCC. Bonds rated CCC have certain identifiable characteristics
which,  if not  remedied,  may  lead to  default.  |_| CC.  Bonds  rated  CC are
considered minimally protected.  Default in payment of interest and/or principal
seems  probable  over time.  |_| C.  Bonds  rated C are in  imminent  default in
payment of interest or principal.  |_| DDD and below.  Bonds rated DDD, DD and D
are in default on interest and/or principal payments. DDD represents the highest
potential for recovery on these bonds, and D represents the lowest potential for
recovery.

Duff & Phelps. The ratings of Duff & Phelps are as follows:
|_|  AAA.  These  are  judged  to be the  "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 and greater in periods of economic  stress.  |_| BBB+,
BBB & BBB-. These have below average protection factors but are still considered
sufficient for prudent  investment.  They have considerable  variability in risk
during economic cycles.  |_| BB+, BB & BB-. These are below investment grade but
are  deemed to be able to meet  obligations  when due.  Present  or  prospective
financial  protection  factors  fluctuate  according to industry  conditions  or
company  fortunes.  Overall  quality may move up or down  frequently  within the
category. |_| B+, B & B-. These are below investment grade and possess 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. These are
defaulted debt obligations. The issuer failed to meet scheduled principal and/or
interest payments.

Municipal Notes

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

Standard & Poor's.  S&P's ratings for municipal notes due in three years or less
are SP-1,  SP-2, and SP-3. SP-1 describes  issues with a very strong capacity to
pay  principal  and interest and compares with bonds rated A by S&P. If modified
by a plus sign, it compares  with bonds rated AA or AAA by S&P.  SP-2  describes
issues with a satisfactory capacity to pay principal and interest,  and compares
with bonds  rated BBB by S&P.  SP-3  describes  issues  that have a  speculative
capacity to pay principal and interest.


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

Corporate Debt

      The  other  debt  securities  included  in the  definition  of  temporary
defensive   investments  the  Fund  may  hold  are  corporate  (as  opposed  to
municipal)  debt  obligations.  The  Moody's,  S&P  and  Fitch  corporate  debt
ratings  do not differ  materially  from  those set forth  above for  municipal
bonds.
Commercial Paper

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

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

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

                                  Appendix C

        OppenheimerFunds Special Sales Charge Arrangements and Waivers

In certain cases,  the initial sales charge that applies to purchases of Class A
shares1 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.2  That is because
of the  economies of sales  efforts  realized by  OppenheimerFunds  Distributor,
Inc.,  (referred  to in this  document as the  "Distributor"),  or by dealers or
other  financial  institutions  that offer  those  shares to certain  classes of
investors.

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.

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 plans3 (4)
Group  Retirement  Plans4 (5) 403(b)(7)  custodial  plan accounts (6) Individual
Retirement Accounts ("IRAs"), including traditional IRAs,
        Roth IRAs, SEP-IRAs, SARSEPs or SIMPLE plans

The  interpretation  of these  provisions as to the  applicability  of a special
arrangement  or waiver in a  particular  case is in the sole  discretion  of the
Distributor or the transfer agent (referred to in this document as the "Transfer
Agent")  of  the  particular   Oppenheimer   fund.  These  waivers  and  special
arrangements  may be amended or terminated at any time by a particular fund, the
Distributor, and/or OppenheimerFunds,  Inc. (referred to in this document as the
"Manager"). Waivers that apply at the time shares are redeemed must be requested
by the shareholder and/or dealer in the redemption request.

- --------------
1. Certain  waivers  also  apply to Class M shares  of  Oppenheimer  Convertible
   Securities Fund.
2. In the case of Oppenheimer Senior Floating Rate Fund, a  continuously-offered
   closed-end  fund,  references to contingent  deferred  sales charges mean the
   Fund's  Early  Withdrawal   Charges  and  references  to  "redemptions"  mean
   "repurchases" of shares.
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.

 I. 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 shares  purchased  under these  waivers that are
subject to the Class A contingent  deferred sales charge,  the Distributor  will
pay the  applicable  commission  described  in the  Prospectus  under  "Class  A
Contingent  Deferred  Sales  Charge."2  This  waiver  provision  applies to: |_|
Purchases of Class A shares  aggregating  $1 million or more. |_| Purchases by a
Retirement Plan (other than an IRA or 403(b)(7)
        custodial plan) that:
(1)   buys shares costing $500,000 or more, or
(2)        has, at the time of purchase, 100 or more eligible employees 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.
|_|   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.
|_|     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).
|_|     Purchases by a Retirement Plan whose record keeper had a cost-allocation
        agreement with the Transfer Agent on or before May 1, 1999.
