About the Fund

The Fund's Objective and Investment Strategies

What Is the Fund's Investment  Objective?  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.
   
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),  interests in municipal
leases,  and tax-exempt  commercial  paper. Most of the securities the Fund buys
must be "investment grade" (the four highest rated 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. The Fund may
also use hedging  instruments  and certain  derivative  investments to a limited
extent to try to manage  investment  risks.  These  investments  are more  fully
explained in "About the Fund's Investments," below.
    
   
         |X| How Does the Manager  Decide  What  Securities  to Buy or Sell?  In
selecting  securities  for the  Fund,  the  Manager  currently  looks  primarily
throughout  California for municipal securities using a variety of factors which
may change over time and may vary in particular cases: o Securities that provide
high income o The goal of  spreading  risk among a wide range of  securities  of
different issuers within the state, including different
                      agencies and municipalities
                  |_| Issues with favorable credit characteristics
      |_| Special situations among issuers that provide opportunities for value
    
Who Is the Fund Designed For? The Fund is designed for investors who are seeking
income exempt from federal and California income taxes. It does not seek capital
gains or growth.  Because it invests in tax-exempt  securities,  the Fund is not
appropriate  for  retirement  plan  accounts or for investors who want to pursue
capital growth.

Main Risks of Investing in the Fund

         All investments carry risks to some degree.  For bond funds one risk is
that the market prices of the fund's  investments  will  fluctuate  when general
interest rates change (this is known as "interest  rate risk").  Another risk is
that the  issuer  of the bond will  experience  financial  difficulties  and may
default on its obligation to pay interest and repay  principal (this is referred
to as "credit risk").  These general  investment  risks and the special risks of
certain types of investments that the Fund may hold are described below.

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

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

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

         An  investment  in the Fund is not a deposit  of any  bank,  and is not
insured or guaranteed by the Federal Deposit Insurance  Corporation or any other
government agency.
   
         |X| Credit  Risk.  Municipal  securities  are  subject to credit  risk.
Credit risk relates to the ability of the issuer of a municipal security to make
interest  and  principal  payments  on the  security  as they become due. If the
issuer fails to pay interest, the Fund's income may be reduced and if the issuer
fails to repay principal, the value of that bond 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.
    
         |X|  Interest  Rate  Risks.  In  addition  to credit  risks,  municipal
securities  are  subject  to changes in value  when  prevailing  interest  rates
change. When interest rates fall, the values of outstanding municipal securities
generally  rise,  and the bonds may sell for more than their face  amount.  When
interest rates rise, the values of outstanding  municipal  securities  generally
decline,  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.  When the average maturity of the Fund's portfolio is longer,  its share
price may fluctuate more when interest rates change.

         |X| Risks of Non-Diversification -- Investments in California Municipal
Securities.  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 a single state, could
result in greater  fluctuations  of the  Fund's  share  prices due to  economic,
regulatory or political problems in California.
   
         |X| There are Special Risks in Using Derivative  Investments.  The Fund
may 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  assets,
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.  However,  using derivatives can cause the Fund to lose
money on its investments and/or increase the volatility of its share prices.
    
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 calendar years since the Fund's inception  (11/3/88) and by
showing how the average  annual total  returns of the Fund's  shares  compare to
those of a broad-based  market index. The Fund's past investment  performance is
not necessarily an indication of how the Fund will perform in the future.

                  [See Bar Chart in Appendix to the Prospectus]


For  the  period  from  1/1/98  through  9/30/98,  the  cumulative  return  (not
annualized) for Class A shares was 5.96%.  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 period shown in the bar
chart,  the highest  return (not  annualized)  for a calendar  quarter was 8.65%
(1Q'95) and the lowest return for a calendar quarter was -6.00% (1Q'94).

* Inception  dates of  classes:  Class A:  11/3/88;  Class B:  5/1/93;  Class C:

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

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

Fees and Expenses of the Fund

         The Fund pays a variety of  expenses  directly  for  management  of its
assets,  administration,  distribution of its shares and other  services.  Those
expenses are subtracted from the Fund's assets to calculate the Fund's net asset
value per share.  All  shareholders  therefore  pay those  expenses  indirectly.
Shareholders  pay other  expenses  directly,  such as sales  charges and account
transaction  charges.  The following  tables are provided to help you understand
the fees and  expenses  you may pay if you buy and hold shares of the Fund.  The
numbers below are based on the Fund's expenses during the fiscal year ended July
31, 1998.

pays.

Examples.  These examples are intended to help you compare the cost of investing
in the Fund with the cost of investing in other mutual funds.

The examples assume that you invest $10,000 in a class of shares of the Fund for
the time periods indicated,  and reinvest your dividends and distributions.  The
first  example  assumes  that you redeem all of your  shares at the end of those
periods.  The second  example  assumes you keep your shares.  Both examples also
assume  that  your  investment  has a 5% return  each year and that the  class's
operating  expenses  remain the same.  Your actual  costs may be higher or lower
because expenses will vary over time.  Based on these  assumptions your expenses
would be as follows:


   
If shares are redeemed:   1 year     3 years     5 years         10 years(1)
Class A Shares            $564       $754        $ 960             $1,553
Class B Shares            $670       $826        $1,107            $1,593
Class C Shares            $269       $523        $ 902             $1,965

If shares are 
not redeemed:            1 year      3 years    5 years          10 years(1)
Class A Shares           $564         $754       $960               $1,553
Class B Shares           $170         $526       $907               $1,593
Class C Shares           $169         $523       $902               $1,965
    

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 Fund's  goal is to seek a high
level of interest income that is exempt from federal and California income taxes
by investing in municipal  securities,  while trying to preserve capital.  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 Statement of Additional  Information contains more detailed information
about the Fund's investment policies and risks.
   
         |X| What  Municipal  Securities  Does the Fund Invest In? The Fund buys
municipal  bonds  and  notes,  tax-exempt  commercial  paper,   certificates  of
participation in municipal leases and other debt obligations.
    

   
         California  municipal  securities,   on  which  the  Fund  focuses  its
investments, are municipal securities that are not subject (at the time they are
issued) to California  individual  income tax, in the opinion of bond counsel to
the issuer. 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
    



<PAGE>


         The Fund  may  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).

         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  values  of
longer-term bonds are more affected by changes in interest rates than short-term
bonds. Therefore,  the longer the average maturity of the Fund's portfolio,  the
more its share prices generally will be affected by changes in interest rates.

         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  invest  in  municipal
securities that are "general obligations," secured by the issuer's pledge of its
full faith, credit and taxing power for the payment of principal and interest.

         The Fund can also 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 of those revenue  obligations
are private  activity bonds that pay interest that may be a tax preference  item
for investors subject to alternative minimum tax.

         |X|  Ratings  of  Municipal  Securities  the  Fund  Buys.  Most  of the
municipal  securities  the  Fund  buys  are  "investment  grade"  at the time of
purchase.  The Fund limits its  investments in municipal  securities that at the
time of purchase  are not  "investment-grade"  to not more than 25% of its total
assets.  "Investment  grade"  securities are those rated within the four highest
rating  categories  of  Moody's,  Standard  & Poor's,  Fitch or Duff & Phelps or
another nationally recognized rating organization, or (if unrated) judged by the
Manager to be investment grade. Rating categories are described in the Statement
of Additional Information. If the securities are not rated, the Manager will use
its judgment to assign a rating category  equivalent to that of a rating agency.
A reduction in the rating of a security  after its purchase by the Fund will not
automatically require the Fund to dispose of that security. However, the Manager
will evaluate those  securities to determine  whether to keep them in the Fund's
portfolio.

   
         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.
    

         o  Special  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-rated municipal securities.  Securities
that are (or that have fallen) below investment grade entail a greater risk that
the issuers of such securities may not meet their debt obligations.  However, by
limiting its investments in  non-investment  grade  municipal  securities to not
more than 25% of its  assets,  the Fund may  reduce  the effect of some of these
risks on its share price and income.

         |X| Municipal Lease Obligations. Municipal leases are used by state and
local  government  authorities  to obtain  funds to acquire  land,  equipment or
facilities.  The Fund may invest in certificates of participation that represent
a proportionate interest in payments made under municipal lease obligations.  If
the government  stops making payments or transfers its payment  obligations to a
private entity, the obligation could lose value or become taxable.

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

Other Investment  Strategies.  To seek its objective,  the Fund can also use the
investment  techniques and strategies  described below. These techniques involve
certain risks or are designed to help reduce some of the risks.

         |X| Floating  Rate/Variable  Rate  Obligations.  Some of the  municipal
securities  the Fund can  purchase  have  variable or floating  interest  rates.
Variable rates are adjustable at stated periodic  intervals.  Floating rates are
automatically   adjusted   according  to  a  specified   market  rate  for  such
investments,  such as the  percentage of the prime rate of a bank, or the 91-day
U.S.  Treasury Bill rate.  These  obligations  may be secured by bank letters of
credit or other credit support arrangements.

         Certain  types of variable  rate bonds known as "inverse  floaters" pay
interest  rates  that  vary as the  yields  generally  available  on  short-term
tax-exempt  bonds change.  However,  the yields on inverse  floaters move in the
opposite  direction of yields on short-term bonds in response to market changes.
As interest rates rise,  inverse floaters produce less current income, and their
market value can become  volatile.  Inverse  floaters are a type of  "derivative
security."  Some have a "cap," so that if  interest  rates rise above the "cap,"
the security pays  additional  interest  income.  If rates do not rise above the
"cap," the Fund will have paid an  additional  amount for a feature  that proves
worthless.  The Fund  anticipates  that it will  invest not more than 10% of its
total assets in inverse floaters.

         |X| Other Derivatives. The Fund may also invest in municipal derivative
securities  that pay  interest  that depends on an external  pricing  mechanism.
Examples of securities  having  external  pricing  mechanisms  are interest rate
swaps, municipal bond indices or swap indices.

         |X|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.  These terms refer to securities that
have been created and for which a market exists, but which are not available for
immediate  delivery.  The Fund  does  not  intend  to make  such  purchases  for
speculative purposes.  During the period between the purchase and settlement, no
payment is made for the security  and no interest  accrues to the buyer from the
investment.  There  is a risk of loss to the Fund if the  value of the  security
declines prior to the settlement date.

         |X| Puts and  Stand-By  Commitments.  The  Fund may  acquire  "stand-by
commitments" or "puts" with respect to municipal securities. The Fund would have
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 will acquire  stand-by  commitments or puts solely to
enhance portfolio liquidity.
   
         |X| Illiquid Securities.  Under the policies and procedures established
by the Fund's Board of Trustees,  the Manager  determines  the  liquidity of the
Fund's  investments.  Investments  may be illiquid  because of the absence of an
active  trading  market,  making it  difficult  to value them or dispose of them
promptly at an acceptable  price.  The Fund will not invest more than 10% of its
net assets in illiquid  securities  (the Board may increase  that limit to 15%).
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.
    

   
     |X| Hedging.  The Fund may  purchase and sell certain  kinds of futures
contracts,  put and call  options,  and  options  on futures  and  broadly-based
municipal bond indices,  or enter into interest rate swap agreements.  These are
all  referred  to as  "hedging  instruments."  The  Fund  does  not use  hedging
instruments  for  speculative  purposes,  and has limits on the use of them. The
Fund  does  not use  hedging  instruments  to a  substantial  degree  and is not
required to use them in seeking its goal.
    
         The Fund may buy and sell options and futures for a number of purposes.
It may do so to try to manage its exposure to the possibility that the prices of
its  portfolio  securities  may  decline,  or to  establish  a  position  in the
securities   market  as  a  temporary   substitute  for  purchasing   individual
securities.  It may do so to try to manage its  exposure  to  changing  interest
rates.  Some of these  strategies  hedge  the  Fund's  portfolio  against  price
fluctuations. Other hedging strategies, such as buying futures and call options,
tend to increase the Fund's exposure to the securities market.

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

         Options  trading  involves  the payment of premiums and has special tax
effects  on the  Fund.  There  are  also  special  risks in  particular  hedging
strategies. For example, interest rate swaps are subject to credit risks (if the
other party fails to meet its  obligations) and also to interest rate risks. The
Fund could be obligated to pay more under its swap  agreements  than it receives
under them, as a result of interest  rate  changes.  The Fund may not enter into
swaps with respect to more than 25% of its total assets.
   
Temporary  Defensive  Investments.  The Fund may  invest up to 100% of its total
assets in temporary  defensive  investments  from time to time.  This may happen
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 of those  temporary  defensive
investments may not be tax-exempt,  and therefore when making those  investments
the Fund may not  achieve its  objective.  The Fund may also hold these types of
temporary  investments  pending the investment of proceeds from the sale of Fund
shares or  portfolio  securities,  or to meet  anticipated  redemptions  of Fund
shares.
    
Year 2000 Risks.  Because  many  computer  software  systems in use today cannot
distinguish  the year 2000 from the year 1900,  the  markets for  securities  in
which the Fund  invests  could be  detrimentally  affected by computer  failures
beginning  January 1, 2000.  Failure of  computer  systems  used for  securities
trading could result in settlement and liquidity problems for the Fund and other
investors.  That  failure  could have a negative  impact on handling  securities
trades,  pricing and accounting  services.  Data processing errors by government
issuers of securities could result in economic uncertainties,  and those issuers
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 and other parties.  Therefore, any failure of the
computer  systems  of those  parties  to deal with the year 2000 may also have a
negative  affect on the services  they  provide to the Fund.  The extent of that
risk cannot be ascertained at this time.

How the Fund is Managed

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

         The  Manager has  operated as an  investment  advisor  since 1959.  The
Manager  (including   subsidiaries)   currently  manages  investment  companies,
including other  Oppenheimer  funds,  with assets of more than $85 billion as of
September  30,  1998,  and with more than 4 million  shareholder  accounts.  The
Manager is located at Two World Trade  Center,  34th Floor,  New York,  New York
10048-0203.

     |X| Portfolio Manager. The Portfolio manager of the Fund is Jerry Webman, a
Senior Vice  President  of the  Manager.  Mr.  Webman is the person  principally
responsible for the day-to-day  management of the Fund's portfolio,  and has had
this  responsibility  since April 20, 1996. Mr. Webman also serves as an officer
and  portfolio   manager  for  other   Oppenheimer   funds.   Prior  to  joining
OppenheimerFunds,   Mr.  Webman  was  an  officer  and  portfolio  manager  with
Prudential Mutual Funds Investment Management, Inc.

         |X| Advisory Fees. Under the Investment  Advisory  Agreement,  the Fund
pays the Manager an advisory fee at an annual rate which  declines on additional
assets as the Fund grows:  0.60% 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 in excess of $1  billion.  The Fund's  management  fee for its
last fiscal year ended July 31, 1998, was 0.56% of average annual net assets for
Class A, Class B and Class C shares.



About Your Account


How to Buy Shares

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

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

   
         |X| Buying Shares Through the Distributor. Complete an OppenheimerFunds
New Account Application and return it with a check payable to  "OppenheimerFunds
Distributor,  Inc." Mail it to P.O. Box 5270,  Denver,  Colorado  80217.  If you
don't list a dealer on the  application,  the Distributor will act as your agent
in buying the shares.  However,  we recommend  that you discuss your  investment
with a financial advisor before your make a purchase to be sure that the Fund is
appropriate for you.
    
         |X| Buying Shares by Federal Funds Wire.  Shares purchased  through the
Distributor  may be paid for by Federal  Funds wire.  The minimum  investment is
$2,500.  Before  sending  a wire,  call the  Distributor's  Wire  Department  at
1-800-525-7048  to notify the  Distributor of the wire,  and to receive  further
instructions.

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

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

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

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

         |_| The minimum  investment  requirement  does not apply to reinvesting
dividends  from the Fund or other  Oppenheimer  funds (a list of them appears in
the Statement of Additional Information,  or you can ask your dealer or call the
Transfer Agent), or reinvesting  distributions  from unit investment trusts that
have made arrangements with the Distributor.

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

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


         The net asset value per share is  determined  by dividing  the value of
the Fund's net  assets  attributable  to a class by the number of shares of that
class that are  outstanding.  To determine net asset value,  the Fund's Board of
Trustees has established  procedures to value the Fund's securities,  in general
based on market  value.  The Board has adopted  special  procedures  for valuing
illiquid  securities and  obligations  for which market values cannot be readily
obtained.

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

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


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

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

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

         |X| Class C Shares. If you buy Class C shares,  you pay no sales charge
at the time of purchase,  but you will pay an annual asset-based sales charge if
you sell your shares  within 12 months of buying them,  you will  normally pay a
contingent  deferred  sales charge of 1%, as described in "How Can I Buy Class C
Shares?" below.

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

         The  discussion  below is not  intended  to be  investment  advice or a
recommendation,  because each investor's financial considerations are different.
You should  review these factors with your  financial  advisor.  The  discussion
below  assumes  that  you will  purchase  only one  class of  shares,  and not a
combination of shares of different classes.

         |X| How  Long Do You  Expect  to Hold  Your  Investment?  While  future
financial needs cannot be predicted with certainty,  knowing how long you expect
to hold your investment  will assist you in selecting the  appropriate  class of
shares.  Because of the effect of  class-based  expenses,  your choice will also
depend on how much you plan to invest.  For example,  the reduced  sales charges
available  for larger  purchases  of Class A shares may,  over time,  offset the
effect of paying an initial  sales  charge on your  investment,  compared to the
effect over time of higher class-based  expenses on shares of Class B or Class 
C.

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

         However, if you plan to invest more than $100,000 for the shorter term,
then as your investment horizon increases toward six years, Class C shares might
not be as advantageous as Class A shares. That is because the annual asset-based
sales  charge on Class C shares will have a greater  impact on your account over
the longer term than the reduced  front-end  sales charge  available  for larger
purchases of Class A shares.

         And for  investors who invest $1 million or more, in most cases Class A
shares will be the most  advantageous  choice,  no matter how long you intend to
hold your shares.  For that reason,  the  Distributor  normally  will not accept
purchase  orders of  $500,000 or more of Class B shares or $1 million or more of
Class C shares from a single investor.
   
         |_|  Investing  for the Longer  Term.  If you are  investing  less than
$100,000 for the longer-term,  for example for retirement,  and do not expect to
need  access  to your  money  for  seven  years or more,  Class B shares  may be
appropriate.
    
         Of course,  these examples are based on approximations of the effect of
current sales charges and expenses projected over time, and do not detail all of
the  considerations  in  selecting a class of shares.  You should  analyze  your
options carefully with your financial advisor before making that choice.


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

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

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

How Can I Buy Class A Shares?  Class A shares are sold at their offering  price,
which is normally net asset value plus an initial sales charge. However, in some
cases,  described  below,  purchases are not subject to an initial sales charge,
and the  offering  price will be the net asset value.  In other  cases,  reduced
sales  charges may be  available,  as  described  below or in the  Statement  of
Additional Information.  Out of the amount you invest, the Fund receives the net
asset value to invest for your account.

         The sales charge  varies  depending on the amount of your  purchase.  A
portion of the sales charge may be retained by the  Distributor  or allocated to
your dealer as  commission.  The  Distributor  reserves the right to reallow the
entire  commission to dealers.  The current  sales charge rates and  commissions
paid to dealers and brokers are as follows:

</TABLE>

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

         If you  redeem any of those  shares  within 18 months of the end of the
calendar month of their purchase, a contingent deferred sales charge (called the
"Class A contingent  deferred sales charge") may be deducted from the redemption
proceeds.  That  sales  charge  will be equal to 1.0% of the  lesser  of (1) the
aggregate  net asset  value of the  redeemed  shares  at the time of  redemption
(excluding  shares  purchased  by  reinvestment  of  dividends  or capital  gain
distributions)  or (2) the  original  net asset  value of the  redeemed  shares.
However,  the Class A  contingent  deferred  sales  charge  will not  exceed the
aggregate  amount of the commissions the Distributor  paid to your dealer on all
purchases of Class A shares of all Oppenheimer  funds you made that were subject
to the Class A contingent deferred sales charge.

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

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

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

         |X|  Waivers  of  Class A  Sales  Charges.  The  Class  A  initial  and
contingent deferred sales charges are not imposed in the circumstances described
in "Reduced Sales Charges" in the Statement of Additional Information.  In order
to receive a waiver of the Class A contingent  deferred  sales charge,  you must
notify the  Transfer  Agent when  purchasing  shares  whether any of the special
conditions apply.

How Can I Buy Class B  Shares?  Class B shares  are sold at net asset  value per
share without an initial sales charge.  However,  if Class B shares are redeemed
within 6 years of their  purchase,  a contingent  deferred  sales charge will be
deducted from the  redemption  proceeds.  The Class B contingent  deferred sales
charge is paid to  compensate  the  Distributor  for its  expenses of  providing
distribution-related services to the Fund in connection with the sale of Class B
shares.
   
         The contingent deferred sales charge will be based on the lesser of the
net asset value of the redeemed shares at the time of redemption or the original
net asset value. The contingent deferred sales charge is not imposed on:
    
     |_| the amount of your  account  value  represented  by an  increase in net
asset value over the initial purchase price or

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

              |_| shares redeemed in the special circumstances  described in the
Appendix in 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.

   
         |X|   Automatic   Conversion   of  Class  B  Shares.   Class  B  shares
automatically  convert to Class A shares 72 months after you purchase them. This
conversion feature relieves Class B shareholders of the asset-based sales charge
that applies to Class B shares under the Class B Distribution  and Service Plan,
described  below. The conversion is based on the relative net asset value of the
two classes,  and no sales load or other charge is imposed.  When Class B shares
convert,  any other Class B shares that were  acquired  by the  reinvestment  of
dividends and distributions on the converted shares will also convert to Class A
shares. The conversion feature is subject to the continued availability of a tax
ruling described in the Statement of Additional Information.
    
   
How Can I Buy Class C  Shares?  Class C shares  are sold at net asset  value per
share without an initial sales charge.  However,  if Class C shares are redeemed
within 12 months of their purchase,  a contingent  deferred sales charge of 1.0%
will be deducted from the redemption  proceeds.  The Class C contingent deferred
sales charge is paid to compensate the Distributor for its expenses of providing
distribution-related services to the Fund in connection with the sale of Class C
shares.
    
         The contingent deferred sales charge will be based on the lesser of the
net asset value of the redeemed shares at the time of redemption or the original
net asset value. The contingent deferred sales charge is not imposed on:

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.

         |X|  Service  Plan for Class A Shares.  The Fund has  adopted a Service
Plan for Class A shares.  It  reimburses  the  Distributor  for a portion of its
costs  incurred  for  services  provided to  accounts  that hold Class A shares.
Reimbursement  is made quarterly at an annual rate of up to 0.25% of the average
annual net assets of Class A shares of the Fund. The Distributor  currently uses
all of those fees to  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.

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

         The  asset-based  sales  charge and service fees  increase  Class B and
Class C expenses  by 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  on-going
basis,  over time these fees will increase the cost of your  investment  and may
cost you more than other types of sales charges.

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

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

         The  Distributor  currently  pays  sales  commissions  of  0.75% of the
purchase  price of Class C shares to dealers from its own  resources at the time
of sale.  Including the advance of the service fee, the total amount paid by the
Distributor  to the  dealer at the time of sale of Class C shares  is  therefore
1.00% of the purchase price. The Distributor  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.

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

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

account on AccountLink, you may have the proceeds sent to that bank account.

Are There Limits on Amounts Redeemed by Telephone?

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

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

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

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

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

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

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

         |_| You may not write a check  that  would  require  the Fund to redeem
shares that were  purchased by check or Asset Builder Plan  payments  within the
prior 10 days.
         |_| Don't use your  checks if you  changed  your Fund  account  number,
until you receive new checks.

Can I Sell Shares Through My Dealer?  The Distributor  has made  arrangements to
repurchase  Fund shares from  dealers and brokers on behalf of their  customers.
Brokers or dealers may charge for that  service.  If your shares are held in the
name of your dealer, you must redeem them through your dealer.

How to Exchange Shares

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

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

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

     |_| You must hold the shares you buy when you establish your account for at
least 7 days before you can exchange them. After the account is open 7 days, you
can exchange shares every regular business day.

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

     |_|  Before  exchanging  into a  fund,  you  should  obtain  and  read  its
prospectus.

         Shares  of a  particular  class of the Fund may be  exchanged  only for
shares of the same class in the other  Oppenheimer  funds. For example,  you can
exchange Class A shares of this Fund only for Class A shares of another fund. In
some  cases,  sales  charges may be imposed on  exchange  transactions.  For tax
purposes,  exchanges of shares  involve a sale of the shares of the fund you own
and a purchase  of the shares of the other  fund,  which may result in a capital
gain or loss.  Please  refer to "How to  Exchange  Shares" in the  Statement  of
Additional Information for more details.

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

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

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

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

Are There  Limitations  on Exchanges?  There are certain  exchange  policies you
should be aware of:
   
         |_| Shares are normally  redeemed from one fund and purchased  from the
other fund in the exchange transaction on the same regular business day on which
the Transfer  Agent  receives an exchange  request that conforms to the policies
described above. It must be received by the close of The New York Stock Exchange
that day, which is normally 4:00 P.M. but may be earlier on some days.  However,
either fund may delay the purchase of shares of the fund you are exchanging into
up to  seven  days if it  determines  it would be  disadvantaged  by a  same-day
exchange.  For example, the receipt of multiple exchange requests from a "market
timer"  might  require the Fund to sell  securities  at a  disadvantageous  time
and/or price.
    
         |_|  Because  excessive  trading  can hurt  fund  performance  and harm
shareholders, the Fund reserves the right to refuse any exchange request that it
believes will disadvantage it, or to refuse multiple exchange requests submitted
by a shareholder or dealer.
         |_| The Fund may amend,  suspend or terminate the exchange privilege at
any time.  Although the Fund will  attempt to provide you notice  whenever it is
reasonably able to do so, it may impose these changes at any time.
         |_| If the Transfer  Agent  cannot  exchange all the shares you request
because of a restriction cited above, only the shares eligible for exchange will
be exchanged.

Shareholder Account Rules and Policies

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

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

         |X| The Transfer  Agent will record any telephone  calls to verify data
concerning  transactions  and has  adopted  other  procedures  to  confirm  that
telephone  instructions  are  genuine,  by  requiring  callers  to  provide  tax
identification  numbers  and  other  account  data  or by  using  PINs,  and  by
confirming such  transactions  in writing.  The Transfer Agent and the Fund will
not be liable for  losses or  expenses  arising  out of  telephone  instructions
reasonably believed to be genuine.

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

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

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

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

         |X| The Transfer  Agent may delay  forwarding  a check or  processing a
payment  via  AccountLink  for  recently  purchased  shares,  but only until the
purchase payment has cleared. That delay may be as much as 10 days from the date
the shares were  purchased.  That delay may be avoided if you purchase shares by
federal  funds wire or  certified  check,  or arrange  with your bank to provide
telephone or written  assurance to the Transfer Agent that your purchase payment
has cleared.

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

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

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

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

Dividends and Tax Information

Dividends. The Fund intends to declare dividends separately for 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:

     |X| Reinvest All  Distributions  in the Fund. You can elect to reinvest all
dividends and long-term capital gains  distributions in additional shares of the
Fund.

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

         |X| Receive All Distributions in Cash. You can elect to receive a check
for all dividends and long-term capital gains distributions or have them sent to
your bank through AccountLink.

     |X| Reinvest Your Distributions in Another  OppenheimerFunds  Account.  You
can  reinvest  all  distributions  in  the  same  class  of  shares  of  another
Oppenheimer fund account you have established.
   
Taxes. Dividends paid from net investment income earned by the Fund on municipal
securities will be excludable from gross income for Federal income tax purposes.
A portion of a dividend that is derived from  interest paid on certain  "private
activity  bonds"  may be an item of tax  preference  if you are  subject  to the
alternative minimum tax. If the Fund earns interest on taxable investments,  any
dividends  derived  from those  earnings  will be taxable as ordinary  income to
shareholders.
    

         Dividends  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.

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

     |X| Returns of Capital Can Occur. In certain cases,  distributions  made by
the Fund may be considered a non-taxable  return of capital to shareholders.  If
that occurs, it will be identified in notices to shareholders.

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

Financial Highlights

The Financial  Highlights  Table is presented to help you  understand the Fund's
financial  performance  for  the  past 5  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 Peat  Marwick 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.

         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%.

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

     |X| Municipal Bonds. We have classified 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.

                  |_| 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.

                  |_|  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.

                  |_| Private Activity Municipal Securities.  The Tax Reform Act
of 1986  (the "Tax  Reform  Act")  reorganized,  as well as  amended,  the rules
governing tax  exemption for interest on certain types of municipal  securities.
The Tax Reform Act generally did not change the tax treatment of bonds issued in
order to finance governmental  operations.  Thus, interest on general obligation
bonds  issued by or on behalf of state or local  governments,  the  proceeds  of
which are used to finance the  operations of such  governments,  continues to be
tax-exempt.  However, the Tax Reform Act limited the use of tax-exempt bonds for
non-governmental  (private) purposes. More stringent restrictions were placed on
the use of proceeds of such bonds. Interest on certain private activity bonds is
taxable  under  the  revised  rules.  There  is  an  exception  for  "qualified"
tax-exempt private activity bonds, for example,  exempt facility bonds including
certain  industrial  development  bonds,  qualified  mortgage  bonds,  qualified
Section 501(c)(3) bonds, and qualified student loan bonds.

         In addition,  limitations  as to the amount of private  activity  bonds
which each state may issue were  revised  downward by the Tax Reform Act,  which
will reduce the supply of such bonds. The value of the Fund's portfolio could be
affected if there is a reduction in the availability of such bonds.

         Interest on certain private activity bonds issued after August 7, 1986,
which  continues  to be  tax-exempt,  will be treated as a tax  preference  item
subject  to the  alternative  minimum  tax  (discussed  below) to which  certain
taxpayers are subject.  The Fund may hold  municipal  securities the interest on
which (and thus a proportionate share of the  exempt-interest  dividends paid by
the Fund) will be subject to the Federal  alternative minimum tax on individuals
and corporations.

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

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

         To  determine  whether a  municipal  security  is  treated as a taxable
private  activity bond, it is subject to a test for: (a) a trade or business use
and security  interest,  or (b) a private loan  restriction.  Under the trade or
business use and security  interest  test, an  obligation is a private  activity
bond if: (i) more than 10% of the bond  proceeds  are used for private  business
purposes  and (ii) 10% or more of the  payment of  principal  or interest on the
issue is directly or  indirectly  derived from such private use or is secured by
the privately used property or the payments  related to the use of the property.
For certain types of uses, a 5% threshold is substituted for this 10% threshold.

         The term  "private  business use" means any direct or indirect use in a
trade or business  carried on by an  individual  or entity other than a state or
municipal  governmental unit. Under the private loan restriction,  the amount of
bond proceeds that may be used to make private loans is limited to the lesser of
5% or $5.0 million of the proceeds. Thus, certain issues of municipal securities
could lose their  tax-exempt  status  retroactively  if the issuer fails to meet
certain  requirements as to the expenditure of the proceeds of that issue or the
use of the bond-financed  facility. The Fund makes no independent  investigation
of the users of such bonds or their use of  proceeds  of the bonds.  If the Fund
should hold a bond that loses its tax-exempt status  retroactively,  there might
be  an  adjustment  to  the   tax-exempt   income   previously   distributed  to
shareholders.

         Additionally,  a  private  activity  bond  that  would  otherwise  be a
qualified tax-exempt private activity bond will not, under Internal Revenue Code
Section 147(a),  be a qualified bond for any period during which it is held by a
person who is a "substantial user" of the facilities or by a "related person" of
such a substantial user. This "substantial  user" provision applies primarily to
exempt facility bonds,  including  industrial  development  bonds.  The Fund may
invest  in  industrial  development  bonds  and other  private  activity  bonds.
Therefore,  the Fund may not be an appropriate investment for entities which are
"substantial  users" (or persons related to "substantial  users") of such exempt
facilities.  Those entities and persons should consult their tax advisers before
purchasing shares of the Fund.

         A  "substantial  user" of such  facilities  is defined  generally  as a
"non-exempt  person who  regularly  uses part of a facility"  financed  from the
proceeds  of exempt  facility  bonds.  Generally,  an  individual  will not be a
"related  person" under the Internal  Revenue Code unless such individual or the
individual's   immediate  family  (spouse,   brothers,   sisters  and  immediate
descendants)  own directly or indirectly in the aggregate more than 50% in value
of the equity of a corporation or partnership which is a "substantial user" of a
facility financed from the proceeds of exempt facility bonds.
   
         |X| Municipal Notes.  Municipal  securities having a maturity (when the
security  is  issued)  of less than one year are  generally  known as  municipal
notes.  Municipal  notes  generally are used to provide for  short-term  working
capital needs.  Some of the types of municipal  notes the Fund can invest in are
described below.
    
                  |_| Tax  Anticipation  Notes.  These  are  issued  to  finance
working  capital  needs  of  municipalities.   Generally,  they  are  issued  in
anticipation  of various  seasonal tax revenue,  such as income,  sales,  use or
other business taxes, and are payable from these specific future taxes.

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

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

                  |_| Construction Loan Notes. These are sold to provide project
construction   financing  until  permanent  financing  can  be  secured.   After
successful  completion and acceptance of the project,  it may receive  permanent
financing through public agencies, such as the Federal Housing Administration.
   
     |X|  Tax-Exempt  Commercial  Paper.  This  type  of  short-term  obligation
(usually  having a maturity of 270 days or less is issued by a  municipality  to
meet current working capital needs.
    
         |X| Municipal Lease  Obligations.  The Fund's  investments in municipal
lease obligations may be through  certificates of participation that are offered
to investors by public  entities.  Municipal leases may take the form of a lease
or an  installment  purchase  contract  issued  by a state or  local  government
authority to obtain funds to acquire a wide variety of equipment and facilities.

         Some  municipal  lease  securities  may  be  deemed  to  be  "illiquid"
securities.  Their  purchase by the Fund would be limited as described  below in
"Illiquid Securities." From time to time the Fund may invest more than 5% of its
net assets in municipal lease  obligations that the Manager has determined to be
liquid under guidelines set by the Board of Trustees.

         Those guidelines require the Manager to evaluate:

         |_| the frequency of trades and price quotations for such securities;

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

o        the availability of market-makers; and

         |_|  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.

         |X| 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.

         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.  That  legislation
provided  for the  redistribution  of the  surplus  (if any)  from  California's
General Fund to local agencies,  the  reallocation of revenues to local agencies
and the  assumption  of certain  local  obligations  by the State.  It cannot be
predicted  whether  additional  legislation  will be  enacted  in the  future to
redistribute  state revenues.  Even if such legislation 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  returns,  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 subject to state law  limiting the
remedies of a creditor  holding  debt  secured by a mortgage or deed of trust on
real property.

         |_| 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 5.8% in June 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. All major economic regions of the state
grew.  The growth rate for the Los Angeles region has nearly caught up with that
of the San Francisco Bay region, based on employment growth statistics. However,
the  unsettled  conditions in Asian  economies in 1998 may adversely  affect the
state's  export-related  industries,  and therefore the state's  overall rate of
economic growth.
   
         On August 21, 1998,  the Governor of  California  signed the  1998-1999
Budget Act. It  authorizes  state  spending of about $72 billion.  That includes
$57.3 billion from the General Fund, which is a 7.3% increase from 1997-1998. It
also includes spending of $14.7 billion from special funds, an increase of 1.7%.
Before   signing  the  budget  act,   the   Governor   vetoed  $1.5  billion  in
appropriations  adopted  by the state  legislature,  including  $1.4  billion in
General Fund spending.  The Governor  indicated that $250 million of the cuts he
made to  primary  education  costs  were  being  set aside  pending  legislative
consideration of various school reforms.
    


         Continued state economic  expansion and large revenue increases enabled
the Governor and the state  legislature to provide both  significant  tax relief
and  increases in spending  programs in the 1998-1999  budget.  These include an
initial 25%  reduction in vehicle  license  fees,  large  increases in education
funding and cost of living  adjustments and the restoration of grants for social
service programs.


         However,  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.  However, 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+ and in
1997 Fitch 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.

         Los  Angeles  County,  the  nation's  most  populous  county,  has also
experienced  financial  difficulties.  In 1995 the credit rating of the county's
long-term bonds was downgraded for the third time since 1992. 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.  In June 1998,  the Los Angeles  County  Board of  Supervisors  approved a
budget of  approximately  $13.6  billion  for  1998-1999.  That was more than 5%
larger than the 1997-1998 budget,  but did not require cuts in services and jobs
to balance. However, the Board of Supervisors reserved the right to make further
changes to reflect revenue allocation decisions in the final State budget.

         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.  It required each state agency by December 31, 1998,
to address Year 2000 problems in their essential computer systems and to protect
those systems from problems caused by interfacing  with outside systems that are
not Year 2000 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.

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

         |X| 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.

         |X|  When-Issued  and  Delayed  Delivery  Transactions.  The  Fund  can
purchase  securities  on a  "when-issued"  basis,  and may purchase or sell such
securities on a "delayed  delivery" 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  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.
   
         |X|  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.
    
         |X| Puts and  Standby  Commitments.  When  the  Fund  buys a  municipal
security subject to a standby commitment to repurchase the security, the Fund is
entitled  to  same-day  settlement  from the  purchaser.  The Fund  receives  an
exercise price equal to the amortized  cost of the underlying  security plus any
accrued interest at the time of exercise.  A put purchased in conjunction with a
municipal  security  enables the Fund to sell the underlying  security  within a
specified period of time at a fixed exercise price.

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

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

         A put or standby  commitment  increases  the cost of the  security  and
reduces the yield otherwise available from the security.  Any consideration paid
by the Fund for the put or standby  commitment  will be  reflected on the Fund's
books as unrealized  depreciation  while the put or standby  commitment is held,
and a realized  gain or loss when the put or commitment is exercised or expires.
Interest income received by the Fund from municipal  securities  subject to puts
or stand-by  commitments may not qualify as tax exempt in its hands if the terms
of the put or  stand-by  commitment  cause the Fund not to be treated as the tax
owner of the underlying municipal securities.
   
         |X| Repurchase  Agreements.  The Fund may acquire securities subject to
repurchase  agreements.  It may do so for liquidity purposes to meet anticipated
redemptions of Fund shares, or pending the investment of the proceeds from sales
of Fund  shares,  or  pending  the  settlement  of  portfolio  securities.  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.
    
   
         |X| 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.
    

         |X| Loans of Portfolio Securities.  To attempt to raise income or raise
cash for  liquidity  purposes,  the Fund may lend its  portfolio  securities  to
brokers,  dealers and other financial  institutions.  These loans 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.

         |X|  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
         |_|  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:

         |_| buy interest rate futures or municipal bond index  futures,  or

         |_|  buy calls on such futures or on securities.
   
         The Fund is not obligated to use hedging instruments, even though it is
permitted  to use them in the  Manager's  discretion,  as described  below.  The
Fund's  strategy  of  hedging  with  futures  and  options  on  futures  will be
incidental to the Fund's  investment  activities in the underlying  cash market.
The particular  hedging  instruments the Fund can use are described  below.  The
Fund may employ new hedging  instruments and strategies when they are developed,
if those investment methods are consistent with the Fund's investment  objective
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 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,  or a  securities  depository  acting  for  the
Custodian,  will act as the Fund's  escrow agent  through the  facilities of the
Options Clearing  Corporation  ("OCC"),  as to the investments on which the Fund
has  written  calls  traded  on  exchanges,  or as to  other  acceptable  escrow
securities.  In that way, no margin will be required for such transactions.  OCC
will release the  securities  on the  expiration of the calls or upon the Fund's
entering into a closing purchase transaction.

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

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

         The Fund may also write calls on futures  contracts  without owning the
futures contract or securities  deliverable under the contract. To do so, at the
time the call is written,  the Fund must cover the call by segregating in escrow
an equivalent dollar value of liquid assets. The Fund will segregate  additional
liquid  assets if the  value of the  escrowed  assets  drops  below  100% of the
current  value  of  the  future.  Because  of  this  escrow  requirement,  in no
circumstances  would the Fund's receipt of an exercise  notice as to that future
put the Fund in a "short" futures position.

         |_|  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.

     |X| Temporary Defensive Investments.  The securities the Fund may invest in
for temporary defensive purposes include the following:
   
     |_| short-term municipal securities;
    
     |_| obligations issued or guaranteed by the U.S. Government or its agencies
or instrumentalities;

     |_| corporate  debt  securities  rated within the three highest grades by a
nationally recognized rating agency;

     |_| commercial paper rated "A-1" by S&P, or a comparable  rating by another
nationally recognized rating agency; and

     |_|  certificates of deposit of domestic banks with assets of $1 billion or
more.


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

Investment Restrictions

         |X| What Are  "Fundamental  Policies?"  Fundamental  policies are those
policies that the Fund has adopted to govern its investments that can be changed
only by the vote of a "majority" of the Fund's  outstanding  voting  securities.
Under the Investment  Company Act, such a "majority" vote is defined as the vote
of the holders of the lesser of:

     |_| 67% or  more  of the  shares  present  or  represented  by  proxy  at a
shareholder  meeting,  if the holders of more than 50% of the outstanding shares
are present or represented by proxy, or

     |_| more than 50% of the outstanding shares.

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

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

         |_| 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.

         |_| 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."

         |_| 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.


         |_| 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.

         |_| 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.

         |_| 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.

         |_| 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.

         |_| The Fund cannot sell securities short.

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

         |_| 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.

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

         |_| 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:
    
         o  has its own dividends and distributions,
         o  pays certain expenses which may be different for the different
            classes,

         o   may have a different net asset value,
         o may have separate  voting rights on matters in which the interests of
         one class are  different  from the  interests of another  class,  and o
         votes as a class on matters that affect that class alone.

         |_| 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.

2   Reflects fees from 1/1/98 to 7/31/98
3 Committee  position held during a portion of the period shown. 4 Includes $420
deferred under Deferred Compensation Plan described below.
    
   
      |X| 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.
    

         |X| Deferred Compensation Plan for Trustees.  The Board of Trustees has
adopted a Deferred  Compensation  Plan for  disinterested  trustees that enables
them to elect to defer  receipt of all or a portion of the annual  fees they are
entitled to receive from the Fund. Under the plan, the compensation  deferred by
a Trustee  is  periodically  adjusted  as though an  equivalent  amount had been
invested in shares of one or more Oppenheimer funds selected by the Trustee. The
amount  paid to the  Trustee  under the plan will be  determined  based upon the
performance of the selected funds.

         Deferral of Trustees'  fees under the plan will not  materially  affect
the Fund's  assets,  liabilities  or net  income  per  share.  The plan will not
obligate the Fund to retain the services of any Trustee or to pay any particular
level  of  compensation  to any  Trustee.  Pursuant  to an Order  issued  by the
Securities and Exchange Commission, the Fund may invest in the funds selected by
the Trustee under the plan without shareholder  approval for the limited purpose
of determining the value of the Trustee's deferred fee account.
   
         |X| Major  Shareholders.  As of November  2,1998,  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:

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.

         |X| The Investment Advisory Agreement.  The Manager provides investment
advisory  and  management  services  to the Fund  under an  investment  advisory
agreement  between the Manager and the Fund. The Manager selects  securities for
the  Fund's  portfolio  and  handles  its day-to day  business.  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.

         The investment advisory agreement contains an indemnity of the Manager.
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:

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.  Each plan has also been
approved by a vote of the holders of a "majority"  (as defined in the Investment
Company  Act) of the shares of each class.  The Manager cast the vote to approve
the Class C plan as the sole initial holder of Class C shares.
   
         Under  the  plans  the  Manager  and the  Distributor,  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, the purpose for which the payments were made and the identity
of each  recipient  of a  payment.  The  report on the Class B and Class C plans
shall also include the Distributor's distribution costs for the quarter, and any
costs for previous fiscal periods that have been carried forward.  Those reports
are  subject to the review  and  approval  of the  Independent  Trustees  in the
exercise of their fiduciary duty.

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

         Under  the  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,  1998,  payments  under the Plan for
Class A shares  totaled  $728,542,  all of which was paid by the  Distributor to
recipients.  That included $21,461 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.
   
         Payments made under the Class B plan for the fiscal year ended July 31,
1998,   totaled  $991,756   (including  $2,065  paid  to  an  affiliate  of  the
Distributor). The Distributor retained $832,617 of the total paid. Payments made
under the Class C Plan for the fiscal year ended July 31, 1998  totaled  $85,990
(including  $2,722 paid to an affiliate  of the  Distributor).  The  Distributor
retained  $59,727 of the total  paid.  At July 31,  1998,  the  Distributor  had
incurred  unreimbursed  expenses  under  the  Class  B  plan  in the  amount  of
$3,588,025  (equal to 3.11% of the  Fund's  net  assets  represented  by Class B
shares  on  that  date).   At  July  31,  1998,  the  Distributor  had  incurred
unreimbursed  expenses under the Class C plan of $138,504 (equal to 1.22% of the
Fund's net assets represented by Class C shares on that date). If either plan is
terminated  by the Fund,  the Board of  Trustees  may allow the Fund to continue
payments of the asset-based  sales charge to the  Distributor  for  distributing
shares before the plan was terminated.
    
         All  payments  under the Class B and Class C plans are  subject  to the
limitations  imposed  by the  Conduct  Rules  of  the  National  Association  of
Securities  Dealers,  Inc. on payments of asset-based  sales charges and service
fees to NASD members.

Performance of the Fund

Explanation  of  Performance  Terminology.  The Fund uses a variety  of terms to
illustrate  its   performance.   These  terms  include   "standardized   yield,"
"tax-equivalent   yield,"  "dividend  yield,"  "average  annual  total  return,"
"cumulative  total return," "average annual total return at net asset value" and
"total  return at net asset  value."  An  explanation  of how  yields  and total
returns are  calculated  is set forth  below.  The charts  below show the Fund's
performance  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:

         |_| Yields and total returns  measure the performance of a hypothetical
account in the Fund over various periods and do not show the performance of each
shareholder's  account.  Your  account's  performance  will  vary from the model
performance  data if your  dividends  are  received in cash,  or you buy or sell
shares  during the period,  or you bought  your  shares at a different  time and
price than the shares used in the model.
   
|_| The  Fund's  performance  returns  do not  reflect  the  effect  of taxes or
distributions.
    
|_| An investment in the Fund is not insured by the FDIC or any other government
agency.

         |_| The principal value of the Fund's shares,  and its yields and total
returns are not guaranteed and normally will fluctuate on a daily basis.

         |_| When an investor's  shares are redeemed,  they may be worth more or
less than their original cost.

         |_|  Yields  and total  returns  for any given  past  period  represent
historical performance information and are not, and should not be considered,  a
prediction of future yields or returns.

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

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

         |_| Standardized Yield. The "standardized yield" (sometimes referred to
just as "yield") is shown for a class of shares for a stated 30-day  period.  It
is not based on actual  distributions  paid by the Fund to  shareholders  in the
30-day period,  but is a hypothetical yield based upon the net investment income
from the Fund's portfolio  investments for that period.  It may therefore differ
from the "dividend yield" for the same class of shares, described below.

         Standardized  yield is calculated using the following formula set forth
in rules adopted by the Securities and Exchange  Commission,  designed to assure
uniformity in the way that all funds calculate their yields:

                                             a - b      6
                    Standardized Yield - 2 [ -----  + 1) - 1]
                                               cd

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

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

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

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

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

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

                  The  tax-equivalent  yield is based on a 30-day period, and is
computed by dividing  the  tax-exempt  portion of the Fund's  current  yield (as
calculated  above) by one minus a stated income tax rate. The result is added to
the portion (if any) of the Fund's current yield that is not tax-exempt.

   

         The  tax-equivalent  yield may be used to  compare  the tax  effects of
income  derived  from the Fund with income from taxable  investments  at the tax
rates  stated.  Your tax bracket is determined by your Federal 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.

</TABLE>

         |X|  Total  Return  Information.  There are  different  types of "total
returns" to measure the Fund's performance.  Total return is the change in value
of a hypothetical  investment in the Fund over a given period, assuming that all
dividends and capital gains  distributions  are reinvested in additional  shares
and that  the  investment  is  redeemed  at the end of the  period.  Because  of
differences  in expenses  for each class of shares,  the total  returns for each
class are separately  measured.  The cumulative total return measures the change
in value over the entire  period (for  example,  ten years).  An average  annual
total  return  shows the  average  rate of return for each year in a period that
would  produce the  cumulative  total  return over the entire  period.  However,
average annual total returns do not show actual  year-by-year  performance.  The
Fund uses  standardized  calculations for its total returns as prescribed by the
SEC. The methodology is discussed below.

         In calculating  total returns for Class A shares,  the current  maximum
sales charge of 4.75% (as a percentage  of the offering  price) is deducted from
the initial  investment  ("P") (unless the return is shown without sales charge,
as described below).  For Class B shares,  payment of the applicable  contingent
deferred  sales charge is applied,  depending on the period for which the return
is shown: 5.0% in the first year, 4.0% in the second year, 3.0% in the third and
fourth  years,  2.0%  in the  fifth  year,  1.0%  in the  sixth  year  and  none
thereafter.  For Class C shares,  the 1%  contingent  deferred  sales  charge is
deducted for returns for the 1-year period.

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


                    (         )  1/n
                    ( ERV     )  - 1 = Average Annual Total Return
                    ( -----   )       
                    (   P     )

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

                         ERV - P
                         -------- = Total Return
                            P

         |_| Total  Returns at Net Asset  Value.  From time to time the Fund may
also quote a cumulative  or an average  annual total return "at net asset value"
(without  deducting sales charges) for Class A, Class B or Class C shares.  Each
is based on the difference in net asset value per share at the beginning and the
end of the period for a hypothetical investment in that class of shares (without
considering  front-end  or  contingent  deferred  sales  charges) and takes into
consideration the reinvestment of dividends and capital gains distributions.

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

         |_| Lipper Rankings. From time to time the Fund may publish the ranking
of the  performance  of its  Class  A,  Class B or  Class  C  shares  by  Lipper
Analytical Services, Inc. ("Lipper").  Lipper is a widely-recognized independent
mutual fund  monitoring  service.  Lipper  monitors the performance of regulated
investment  companies,  including  the Fund,  and ranks  their  performance  for
various  periods based on  categories  relating to  investment  objectives.  The
performance of the Fund is ranked by Lipper against all other 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  Rankings.  From time to time the Fund may publish the
star  ranking  of the  performance  of its Class A, Class B or Class C shares by
Morningstar,  Inc., an independent mutual fund monitoring  service.  Morningstar
ranks  mutual  funds in  broad  investment  categories:  domestic  stock  funds,
international stock funds, taxable bond funds and municipal bond funds. The Fund
is ranked among municipal bond funds.

         Morningstar star rankings are based on  risk-adjusted  total investment
return.  Investment  return measures a fund's (or class's) one, three,  five and
ten-year average annual total returns (depending on the inception of the fund or
class) in excess of 90-day U.S.  Treasury  bill returns  after  considering  the
fund's  sales  charges  and  expenses.  Risk  measures  a  fund's  (or  class's)
performance below 90-day U.S. Treasury bill returns.  Risk and investment return
are combined to produce star  rankings  reflecting  performance  relative to the
average fund in a fund's category.  Five stars is the "highest" ranking (top 10%
of funds in a category), four stars is "above average" (next 22.5%), three stars
is "average"  (next 35%), two stars is "below average" (next 22.5%) and one star
is "lowest"  (bottom  10%).  The current star ranking is the fund's (or class's)
3-year  ranking  or  its  combined  3-  and  5-year  ranking  (weighted  60%/40%
respectively),  or its combined 3-, 5-, and 10-year  ranking  (weighted 40%, 30%
and 30%, respectively),  depending on the inception date of the fund (or class).
Rankings are subject to change monthly.

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

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

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

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


                               ABOUT YOUR ACCOUNT

How to Buy Shares

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

AccountLink.  When shares are purchased through AccountLink,  each purchase must
be at least $25.  Shares  will be  purchased  on the  regular  business  day the
Distributor  is  instructed  to initiate the  Automated  Clearing  House ("ACH")
transfer to buy the shares.  Dividends will begin to accrue on shares  purchased
with the proceeds of ACH transfers on the business day the Fund receives Federal
Funds for the purchase  through the ACH system  before the close of The New York
Stock Exchange. The Exchange normally closes at 4:00 P.M., but may close earlier
on certain days. If Federal Funds are received on a business day after the close
of the Exchange, the shares will be purchased and dividends will begin to accrue
on the next regular  business  day. The proceeds of ACH  transfers  are normally
received by the Fund 3 days after the transfers are initiated.  The  Distributor
and the Fund are not responsible for any delays in purchasing  shares  resulting
from delays in ACH transmissions.

Reduced Sales Charges.  As discussed in the  Prospectus,  a reduced sales charge
rate may be obtained for Class A shares under Right of Accumulation  and Letters
of Intent  because of the  economies of sales  efforts and reduction in expenses
realized by the  Distributor,  dealers and brokers  making such sales.  No sales
charge is imposed in certain other circumstances described in Appendix C to this
Statement of Additional  Information because the Distributor or dealer or broker
incurs little or no selling expenses.

         |X| Right of Accumulation.  To qualify for the lower sales charge rates
that apply to larger  purchases  of Class A shares,  you and your spouse can add
together:
              |_| Class A and Class B shares you  purchase  for your  individual
                  accounts,  or  for  your  joint  accounts,  or  for  trust  or
                  custodial  accounts on behalf of your children who are minors,
                  and
              |_| current  purchases  of Class A and  Class B shares of the Fund
                  and other  Oppenheimer  funds to reduce the sales  charge rate
                  that applies to current purchases of Class A shares, and
              |_| Class A and Class B shares of Oppenheimer funds you previously
                  purchased  subject to an initial or contingent  deferred sales
                  charge to reduce the sales  charge rate for current  purchases
                  of  Class  A  shares,   provided  that  you  still  hold  your
                  investment in one of the Oppenheimer funds.

         A fiduciary can count all shares purchased for a trust, estate or other
fiduciary  account  (including  one or more  employee  benefit plans of the same
employer) that has multiple  accounts.  The  Distributor  will add the value, at
current offering price, of the shares you previously purchased and currently own
to the value of  current  purchases  to  determine  the sales  charge  rate that
applies. The reduced sales charge will apply only to current purchases. You must
request it when you buy shares.

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

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

Letters of Intent.  Under a Letter of Intent,  if you purchase Class A shares or
Class A and  Class B shares  of the Fund and other  Oppenheimer  funds  during a
13-month  period,  you can reduce  the sales  charge  rate that  applies to your
purchases of Class A shares. The total amount of your intended purchases of both
Class A and Class B shares will  determine the reduced sales charge rate for the
Class A shares purchased during that period.  You can include  purchases made up
to 90 days before the date of the Letter.

         A Letter  of  Intent  is an  investor's  statement  in  writing  to the
Distributor  of the intention to purchase  Class A shares or Class A and Class B
shares of the Fund (and other  Oppenheimer  funds) during a 13-month period (the
"Letter  of  Intent  period").  At the  investor's  request,  this  may  include
purchases made up to 90 days prior to the date of the Letter.  The Letter states
the  investor's  intention to make the  aggregate  amount of purchases of shares
which,  when added to the  investor's  holdings of shares of those  funds,  will
equal  or  exceed  the  amount  specified  in  the  Letter.  Purchases  made  by
reinvestment of dividends or  distributions  of capital gains and purchases made
at net asset value  without  sales  charge do not count  toward  satisfying  the
amount of the Letter.

         A Letter  enables an  investor  to count the Class A and Class B shares
purchased  under the Letter to obtain the reduced sales charge rate on purchases
of Class A shares of the Fund (and other  Oppenheimer  funds) that applies under
the Right of Accumulation to current purchases of Class A shares.  Each purchase
of Class A shares  under the Letter  will be made at the 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  (minimum  $25) for the initial
purchase with your application.  Shares purchased by Asset Builder Plan payments
from bank  accounts  are  subject  to the  redemption  restrictions  for  recent
purchases  described  in  the  Prospectus.   Asset  Builder  Plans  also  enable
shareholders  of  Oppenheimer  Cash  Reserves to use their fund  account to make
monthly automatic purchases of shares of up to four other Oppenheimer funds.

         If you make payments  from your bank account to purchase  shares of the
Fund,  your bank account will be  automatically  debited,  normally four to five
business days prior to the investment dates selected in the Application. Neither
the  Distributor,  the Transfer Agent nor the Fund shall be responsible  for any
delays in purchasing shares resulting from delays in ACH transmission.

         Before  initiating Asset Builder  payments,  obtain a prospectus of the
selected  fund(s) from the Distributor or your financial  advisor and request an
application from the  Distributor,  complete it and return it. The amount of the
Asset  Builder  investment  may be changed or the automatic  investments  may be
terminated  at any time by writing to the Transfer  Agent.  The  Transfer  Agent
requires a  reasonable  period  (approximately  15 days)  after  receipt of such
instructions to implement  them. The Fund reserves the right to amend,  suspend,
or discontinue offering Asset Builder plans at any time without prior notice.

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

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

         The  availability  of three  classes of shares  permits an  investor to
choose  the  method  of  purchasing  shares  that  is more  appropriate  for the
investor.  That may depend on the amount of the purchase, the length of time the
investor  expects to hold  shares,  and other  relevant  circumstances.  Class A
shares 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 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
holiday).  The Exchange's most recent annual  announcement  (which is subject to
change)  states that it will close on New Year's Day,  Martin  Luther King,  Jr.
Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence Day, Labor Day,
Thanksgiving Day and Christmas Day. It may also close on other days.
    
         Dealers  other than Exchange  members may conduct  trading in municipal
securities  on days on which the  Exchange  is closed  (including  weekends  and
holidays) or after 4:00 P.M. on a regular  business day.  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.

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

         |_| Long-term debt securities having a remaining  maturity in excess of
60 days are  valued  based on the mean  between  the  "bid" and  "asked"  prices
determined  by a  portfolio  pricing  service  approved  by the Fund's  Board of
Trustees  or  obtained  by the  Manager  from two  active  market  makers in the
security on the basis of reasonable inquiry.

         |_| The following  securities  are valued at the mean between the "bid"
and "asked" prices  determined by a pricing service approved by the Fund's Board
of Trustees or obtained  by the  Manager  from two active  market  makers in the
security on the basis of reasonable  inquiry:  (1) debt  instruments that have a
maturity  of more than 397 days when  issued,  (2) debt  instruments  that had a
maturity of 397 days or less when  issued and have a remaining  maturity of more
than 60 days, and (3) non-money  market debt  instruments that had a maturity of
397 days or less when issued and which have a remaining maturity of
                  60 days or less.

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

(1) money  market debt  securities  held by a  non-money  market fund that had a
maturity of less than 397 days when issued that have a remaining  maturity of 60
days or less, and

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

         |_|  Securities  not having  readily-available  market  quotations  are
valued at fair value determined under the Board's procedures.

         If the  Manager is unable to locate two market  makers  willing to give
quotes,  a  security  may be priced at the mean  between  the "bid" and  "asked"
prices  provided by a single  active market maker (which in certain cases may be
the "bid" price if no "asked" price is available).

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

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

         When the Fund writes an option, an amount equal to the premium received
is included in the Fund's  Statement of Assets and  Liabilities as an asset.  An
equivalent credit is included in the liability  section.  The credit is adjusted
("marked-to-market")  to reflect the  current  market  value of the  option.  In
determining the Fund's gain on investments, if a call or put written by the Fund
is exercised,  the proceeds are increased by the premium received.  If a call or
put  written  by the Fund  expires,  the Fund  has a gain in the  amount  of the
premium. If the Fund enters into a closing purchase transaction,  it will have a
gain or loss,  depending  on whether the premium  received was more or less than
the cost of the closing  transaction.  If the Fund exercises a put it holds, the
amount the Fund receives on its sale of the underlying  investment is reduced by
the amount of premium paid by the Fund.

How to Sell Shares
   
         The  information   below  supplements  the  terms  and  conditions  for
redeeming shares set forth in the Prospectus.
    
   
Checkwriting.  When a check is presented to the Fund's bank for  clearance,  the
bank will ask the Fund to  redeem a  sufficient  number  of full and  fractional
shares in the  shareholder's  account  to cover the  amount of the  check.  This
enables the  shareholder to continue to receive  dividends on those shares until
the check is presented to the Fund.  Checks may not be presented  for payment at
the  offices of the bank  listed on the check or at the Fund's  custodian  bank.
That limitation does not affect the use of checks for the payment of bills or to
obtain cash at other banks.  The Fund  reserves  the right to amend,  suspend or
discontinue offering Checkwriting privileges at any time without prior notice.
    

   
     In choosing to take advantage of the Checkwriting  privilege by signing the
Account  Application or by completing a Checkwriting  card,  each individual who
signs:  (1) for  individual  accounts,  represents  that they are the registered
owner(s)  of the  shares  of the  Fund in that  account;  (2) for  accounts  for
corporations,  partnerships, trusts and other entities, represents that they are
an officer, general partner, trustee or other fiduciary or agent, as applicable,
duly authorized to act on behalf of such registered owner(s);
    
   

(3)           authorizes the Fund, its Transfer Agent and any bank through which
              the Fund's drafts  (checks) are payable to pay all checks drawn on
              the Fund  account  of such  person(s)  and to redeem a  sufficient
              amount of shares from that account to cover payment of each check;
(4)           specifically  acknowledges that if they choose to permit checks to
              be honored if there is a single  signature on checks drawn against
              joint accounts, or accounts for corporations, partnerships, trusts
              or other  entities,  the signature of any one signatory on a check
              will  be  sufficient  to  authorize  payment  of  that  check  and
              redemption from the account, even if that account is registered in
              the  names of more than one  person  or more  than one  authorized
              signature appears on the Checkwriting card or the Application,  as
              applicable;

(5) understands that the Checkwriting  privilege may be terminated or amended at
any time by the Fund and/or the Fund's  bank;  and (6)  acknowledges  and agrees
that neither the Fund nor its bank shall incur any liability for that  amendment
or termination of checkwriting  privileges or for redeeming shares to pay checks
reasonably believed by them to be genuine, or for returning or not paying checks
that have not been accepted for any reason.
    

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

         |_| Class A shares  that you  purchased  subject  to an  initial  sales
charge or Class A shares on which a contingent  deferred  sales charge was paid,
or
         |_| Class B shares that were subject to the Class B contingent deferred
sales charge when redeemed.

         The  reinvestment  may be made  without  sales  charge  only in Class A
shares of the Fund or any of the other  Oppenheimer  funds into which  shares of
the Fund are  exchangeable  as  described  in "How to  Exchange  Shares"  below.
Reinvestment  will be at the net asset value next  computed  after the  Transfer
Agent receives the  reinvestment  order.  The shareholder  must ask the Transfer
Agent for that  privilege at the time of  reinvestment.  This privilege does not
apply to Class C shares.  The Fund may  amend,  suspend or cease  offering  this
reinvestment  privilege at any time as to shares redeemed after the date of such
amendment, suspension or cessation.

         Any capital  gain that was  realized  when the shares were  redeemed is
taxable,  and reinvestment  will not alter any capital gains tax payable on that
gain.  If there has been a capital  loss on the  redemption,  some or all of the
loss may not be tax  deductible,  depending  on the  timing  and  amount  of the
reinvestment.  Under the Internal  Revenue Code, if the  redemption  proceeds of
Fund  shares on which a sales  charge was paid are  reinvested  in shares of the
Fund or another of the Oppenheimer  funds within 90 days of payment of the sales
charge, the shareholder's basis in the shares of the Fund that were redeemed may
not include the amount of the sales charge  paid.  That would reduce the loss or
increase the gain  recognized  from the  redemption.  However,  in that case the
sales  charge  would  be  added  to the  basis  of the  shares  acquired  by the
reinvestment of the redemption proceeds.

Payments "In Kind".  The Prospectus  states that payment for shares tendered for
redemption is  ordinarily  made in cash.  However,  the Board of Trustees of the
Fund may determine  that it would be  detrimental  to the best  interests of the
remaining  shareholders of the Fund to make payment of a redemption order wholly
or partly in cash.  In that case,  the Fund may pay the  redemption  proceeds in
whole or in part by a distribution "in kind" of securities from the portfolio of
the Fund, in lieu of cash.

         The Fund has elected to be governed by Rule 18f-1 under the  Investment
Company Act.  Under that rule,  the Fund is obligated to redeem shares solely in
cash up to the lesser of $250,000 or 1% of the net assets of the Fund during any
90-day  period for any one  shareholder.  If shares are  redeemed  in kind,  the
redeeming  shareholder  might  incur  brokerage  or other  costs in selling  the
securities for cash. The Fund will value  securities  used to pay redemptions in
kind  using the same  method  the Fund uses to value  its  portfolio  securities
described  above  under  "Determination  of Net Asset  Values Per  Share."  That
valuation will be made as of the time the redemption price is determined.

Involuntary Redemptions. The Fund's Board of Trustees has the right to cause the
involuntary  redemption  of the shares held in any account if the  aggregate net
asset value of those shares is less than $200 or such lesser amount as the Board
may fix.  The Board of Trustees  will not cause the  involuntary  redemption  of
shares in an account if the  aggregate net asset value of such shares has fallen
below the stated minimum solely as a result of market fluctuations. If the Board
exercises  this  right,  it may also fix the  requirements  for any notice to be
given to the  shareholders  in question  (not less than 30 days).  The Board may
alternatively  set  requirements for the shareholder to increase the investment,
or set other terms and conditions so that the shares would not be  involuntarily
redeemed.

Transfers of Shares. A transfer of shares to a different  registration is not an
event that  triggers  the payment of sales  charges.  Therefore,  shares are not
subject to the payment of a contingent deferred sales charge of any class at the
time of  transfer  to the name of another  person or entity.  It does not matter
whether the transfer occurs by absolute assignment,  gift or bequest, as long as
it does not involve,  directly or indirectly,  a public sale of the shares. When
shares  subject to a  contingent  deferred  sales  charge are  transferred,  the
transferred shares will remain subject to the contingent  deferred sales charge.
It  will  be  calculated  as if the  transferee  shareholder  had  acquired  the
transferred  shares in the same manner and at the same time as the  transferring
shareholder.

         If less than all shares  held in an account are  transferred,  and some
but not all shares in the  account  would be subject  to a  contingent  deferred
sales charge if redeemed at the time of transfer,  the  priorities  described in
the  Prospectus  under "How to Buy Shares" for the  imposition of the Class B or
Class C contingent  deferred  sales charge will be followed in  determining  the
order in which shares are transferred.

Special  Arrangements  for  Repurchase  of Shares from Dealers and Brokers.  The
Distributor is the Fund's agent to repurchase its shares from authorized dealers
or brokers  on behalf of their  customers.  Shareholders  should  contact  their
broker or dealer to arrange this type of redemption.  The  repurchase  price per
share will be the net asset value next computed after the  Distributor  receives
an order placed by the dealer or broker.  However, if the Distributor receives a
repurchase  order from a dealer or broker  after the close of The New York Stock
Exchange on a regular business day, it will be processed at that day's net asset
value if the order was received by the dealer or broker from its customers prior
to the time the Exchange closes. Normally, the Exchange closes at 4:00 P.M., but
may do so  earlier  on  some  days.  Additionally,  the  order  must  have  been
transmitted  to and received by the  Distributor  prior to its close of business
that day (normally 5:00 P.M.).

         Ordinarily,  for  accounts  redeemed  by  a  broker-dealer  under  this
procedure, payment will be made within three business days after the shares have
been  redeemed  upon  the  Distributor's  receipt  of  the  required  redemption
documents in proper  form.  The  signature(s)  of the  registered  owners on the
redemption documents must be guaranteed as described in the Prospectus.

Automatic  Withdrawal and Exchange  Plans.  Investors  owning shares of the Fund
valued at $5,000  or more can  authorize  the  Transfer  Agent to redeem  shares
(having  a  value  of at  least  $50)  automatically  on a  monthly,  quarterly,
semi-annual or annual basis under an Automatic  Withdrawal Plan.  Shares will be
redeemed three business days prior to the date requested by the  shareholder for
receipt of the payment.  Automatic  withdrawals of up to $1,500 per month may be
requested  by  telephone  if  payments  are to be made by check  payable  to all
shareholders of record.  Payments must also be sent to the address of record for
the account and the address must not have been changed within the prior 30 days.
Required minimum distributions from OppenheimerFunds-sponsored  retirement plans
may not be arranged on this basis.

         Payments  are  normally  made  by  check,   but   shareholders   having
AccountLink  privileges  (see "How To Buy Shares") may arrange to have Automatic
Withdrawal  Plan  payments  transferred  to the bank account  designated  on the
Account Application or by signature-guaranteed instructions sent to the Transfer
Agent.  Shares are normally  redeemed  pursuant to an Automatic  Withdrawal Plan
three  business  days  before  the  payment  transmittal  date you select in the
Account  Application.  If a  contingent  deferred  sales  charge  applies to the
redemption, the amount of the check or payment will be reduced accordingly.

         The Fund cannot  guarantee  receipt of a payment on the date requested.
The Fund  reserves the right to amend,  suspend or  discontinue  offering  these
plans at any time without prior notice.  Because of the sales charge assessed on
Class A share purchases, shareholders should not make regular additional Class A
share purchases while participating in an Automatic Withdrawal Plan. Class B and
Class C  shareholders  should not  establish  withdrawal  plans,  because of the
imposition of the contingent  deferred sales charge on such withdrawals  (except
where the contingent deferred sales charge is waived as described in "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.

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

         |X|  Automatic  Withdrawal  Plans.  Fund  shares  will be  redeemed  as
necessary to meet withdrawal  payments.  Shares acquired  without a sales charge
will be redeemed first.  Shares  acquired with reinvested  dividends and capital
gains  distributions  will be redeemed next,  followed by shares acquired with a
sales charge,  to the extent  necessary to make withdrawal  payments.  Depending
upon the amount withdrawn,  the investor's  principal may be depleted.  Payments
made under these  plans  should not be  considered  as a yield or income on your
investment.

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

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

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

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

         The  Planholder  may  terminate  a Plan at any time by  writing  to the
Transfer  Agent.  The Fund may also give  directions  to the  Transfer  Agent to
terminate a Plan. The Transfer Agent will also terminate a Plan upon its receipt
of  evidence  satisfactory  to it that the  Planholder  has  died or is  legally
incapacitated.  Upon  termination  of a Plan by the Transfer  Agent or the Fund,
shares that have not been  redeemed will be held in  uncertificated  form in the
name of the  Planholder.  The account will continue as a  dividend-reinvestment,
uncertificated  account unless and until proper  instructions  are received from
the Planholder, his or her executor or guardian, or another authorized person.

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

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

How to Exchange Shares

         As  stated  in  the  Prospectus,   shares  of  a  particular  class  of
Oppenheimer funds having more than one class of shares may be exchanged only for
shares of the same class of other Oppenheimer funds. Shares of Oppenheimer funds
that have a single class without a class designation are deemed "Class A" shares
for this purpose.  You can obtain a current list showing which funds offer which
classes by calling the Distributor at 1-800-525-7048.
         |_| All of the  Oppenheimer  funds  currently  offer  Class  A, B and C
shares  except  Oppenheimer  Money Market Fund,  Inc.,  Centennial  Money Market
Trust,  Centennial Tax Exempt Trust, Centennial Government Trust, Centennial New
York Tax Exempt Trust,  Centennial  California Tax Exempt Trust,  and Centennial
America Fund, L.P., which only offer Class A shares.
         |_| Oppenheimer Main Street California  Municipal Fund currently offers
only Class A and Class B shares.
         |_|  Class B and  Class C  shares  of  Oppenheimer  Cash  Reserves  are
generally  available  only by  exchange  from the same  class of shares of other
Oppenheimer funds or through OppenheimerFunds-sponsored 401 (k) plans.
   
     |_|  Class Y shares of Oppenheimer Real Asset Fund are not exchangeable.
    
         Class A shares of Oppenheimer funds may be exchanged at net asset value
for shares of any money market fund.  Shares of any Money Market Fund  purchased
without a sales charge may be exchanged for shares of Oppenheimer  funds offered
with a sales charge upon payment of the sales  charge.  They may also be used to
purchase  shares of  Oppenheimer  funds subject to a contingent  deferred  sales
charge.

         Shares of  Oppenheimer  Money  Market  Fund,  Inc.  purchased  with the
redemption proceeds of shares of other mutual funds (other than funds managed by
the  Manager  or its  subsidiaries)  redeemed  within  the 30 days prior to that
purchase may  subsequently  be exchanged for shares of other  Oppenheimer  funds
without  being  subject to an initial or contingent  deferred  sales charge.  To
qualify for that  privilege,  the investor or the investor's  dealer must notify
the  Distributor  of  eligibility  for this  privilege at the time the shares of
Oppenheimer  Money Market Fund,  Inc. are  purchased.  If  requested,  they must
supply proof of entitlement to this privilege.

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

         Shares  of  the  Fund   acquired  by   reinvestment   of  dividends  or
distributions  from  any of  the  other  Oppenheimer  funds  or  from  any  unit
investment  trust for which  reinvestment  arrangements  have been made with the
Distributor  may be  exchanged  at net  asset  value  for  shares  of any of the
Oppenheimer funds.

         |_|  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.

         |_| Limits on Multiple Exchange Orders.  The Fund reserves the right to
reject  telephone or written  exchange  requests  submitted in bulk by anyone on
behalf of more than one account.  The Fund may accept  requests for exchanges of
up to 50  accounts  per day from  representatives  of  authorized  dealers  that
qualify for this privilege.

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

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

         In connection with any exchange request, the number of shares exchanged
may be less than the number  requested if the  exchange or the number  requested
would include  shares  subject to a restriction  cited in the Prospectus or this
Statement of Additional Information,  or would include shares covered by a share
certificate  that is not  tendered  with the request.  In those cases,  only the
shares available for exchange without restriction will be exchanged.

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

Dividends, Capital Gains and Taxes

Dividends and Distributions.  Dividends will be payable on shares held of record
at the time of the previous  determination  of net asset value,  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  of the Fund's  assets.  The
Custodian's  responsibilities  include  safeguarding  and controlling the Fund's
portfolio  securities,  and handling the delivery of such securities to and from
the Fund.  It will be the  practice of the Fund to deal with the  Custodian in a
manner uninfluenced by any banking  relationship the Custodian may have with the
Manager and its  affiliates.  The Fund's cash  balances  with the  Custodian  in
excess of  $100,000  are not  protected  by  Federal  Deposit  Insurance.  Those
uninsured balances may at times be substantial.

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

INDEPENDENT AUDITORS' REPORT





The Board of Trustees and Shareholders of
Oppenheimer California Municipal Fund:


We have  audited  the  accompanying  statements  of  investments  and assets and
liabilities  of Oppenheimer  California  Municipal Fund as of July 31, 1998, the
related  statement of  operations  for the year then ended,  the  statements  of
changes in net assets for each of the years in the  two-year  period then ended,
and the financial  highlights for each of the years in the two-year  period then
ended, the seven-month  period ended July 31, 1996, and for each of the years in
the three-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, 1998, by correspondence with the custodian and brokers; and
where  confirmations were not received from brokers, we performed other auditing
procedures.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

                  In  our  opinion,   the  financial  statements  and  financial
highlights  referred to above  present  fairly,  in all material  respects,  the
financial position of Oppenheimer California Municipal Fund as of July 31, 1998,
the results of its  operations  for the year then ended,  the changes in its net
assets for each of the years in the two-year period then ended and the financial
highlights  for  each of the  years  in the  two-year  period  then  ended,  the
seven-month  period  ended  July  31,  1996,  and for  each of the  years in the
three-year period ended December 31, 1995, in conformity with generally accepted
accounting principles.

1.  Represents  the current  interest  rate for a variable rate bond known as an
"inverse  floater"  which pays  interest  at a rate that varies  inversely  with
short-term interest rates. As interest rates rise, inverse floaters produce less
current income.  Their price may be more volatile than the price of a comparable
fixed-rate  security.  Inverse  floaters  amount to  $42,223,625 or 9.88% of the
Fund's net assets at July 31, 1998.

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

3. When-issued security to be delivered and settled after July 31, 1998.

4.  Securities  with  an  aggregate  market  value  of  $1,751,451  are  held in
collateralized  accounts to cover initial  margin  requirements  on open futures
sales contracts. See Note 5 of Notes to Financial Statements.

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

with a front-end  sales  charge.  Class B and Class C shares may be subject to a
contingent deferred sales charge. All classes of shares have identical rights to
earnings,  assets  and  voting  privileges,  except  that each class has its own
distribution and/or service plan,  expenses directly  attributable to that class
and exclusive voting rights with respect to matters affecting that class.  Class
B shares will  automatically  convert to Class A shares six years after the date
of purchase.  The  following  is a summary of  significant  accounting  policies
consistently followed by the Fund.

- --------------------------------------------------------------------------------
INVESTMENT  VALUATION.  Portfolio  securities are valued at the close of the New
York Stock  Exchange on each trading day.  Listed and  unlisted  securities  for
which such  information is regularly  reported are valued at the last sale price
of the day or, in the  absence of sales,  at values  based on the closing bid or
the  last  sale  price  on the  prior  trading  day.  Long-term  and  short-term
"non-money  market" debt  securities are valued by a portfolio  pricing  service
approved by the Board of Trustees.  Such securities which cannot be valued by an
approved portfolio pricing service are valued using  dealer-supplied  valuations
provided the Manager is satisfied that the firm rendering the quotes is reliable
and  that  the  quotes  reflect  current  market  value,  or  are  valued  under
consistently  applied  procedures  established  by  the  Board  of  Trustees  to
determine  fair  value  in good  faith.  Short-term  "money  market  type"  debt
securities having a remaining maturity of 60 days or less are valued at cost (or
last  determined  market  value)  adjusted for  amortization  to maturity of any
premium or  discount.  Options are valued  based upon the last sale price on the
principal  exchange  on which the  option is traded  or, in the  absence  of any
transactions  that day, the value is based upon the last sale price on the prior
trading  date if it is within  the  spread  between  the  closing  bid and asked
prices. If the last sale price is outside the spread, the closing bid is used.

- --------------------------------------------------------------------------------
ALLOCATION OF INCOME,  EXPENSES,  GAINS AND LOSSES. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated daily to
each  class  of  shares  based  upon  the  relative  proportion  of  net  assets
represented  by  such  class.  Operating  expenses  directly  attributable  to a
specific class are charged against the operations of that class.

1. SIGNIFICANT ACCOUNTING POLICIES (continued)

FEDERAL  TAXES.  The Fund intends to continue to comply with  provisions  of the
Internal  Revenue Code  applicable  to  regulated  investment  companies  and to
distribute  all of its  taxable  income,  including  any  net  realized  gain on
investments  not  offset by loss  carryovers,  to  shareholders.  Therefore,  no
federal  income or excise tax provision is required.  At July 31, 1998, the Fund
had available for federal  income tax purposes an unused  capital loss carryover
of approximately $960,000 which expires in 2006.


- --------------------------------------------------------------------------------
TRUSTEES' FEES AND EXPENSES.  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, 1998, a provision of $31,827 was made for the Fund's projected  benefit
obligations,  and payments of $7,543 were made to retired trustees, resulting in
an accumulated liability of $163,318 at July 31, 1998.

       The Board of  Trustees  had  adopted  a  deferred  compensation  plan for
independent Trustees that enables Trustees to elect to defer receipt of all or a
portion of annual  fees they are  entitled to receive  from the Fund.  Under the
plan, the compensation deferred is periodically adjusted as though an equivalent
amount had been  invested  for the Trustee 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.

- --------------------------------------------------------------------------------
DISTRIBUTIONS TO SHAREHOLDERS.  The Fund intends to declare dividends separately
for Class A, Class B and Class C shares from net investment  income each day the
New York Stock  Exchange is open for  business and pay such  dividends  monthly.
Distributions  from net realized gains on investments,  if any, will be declared
at least once each year.

- --------------------------------------------------------------------------------
CLASSIFICATION  OF DISTRIBUTIONS TO SHAREHOLDERS.  Net investment  income (loss)
and net  realized  gain  (loss)  may  differ  for  financial  statement  and tax
purposes.  The  character  of the  distributions  made  during the year from net
investment   income  or  net  realized   gains  may  differ  from  its  ultimate
characterization  for  federal  income  tax  purposes.  Also,  due to  timing of
dividend  distributions,  the fiscal year in which amounts are  distributed  may
differ from the fiscal year in which the income or realized gain was recorded by
the Fund.


                    30 Oppenheimer California Municipal Fund

<PAGE>



================================================================================
The Fund adjusts the  classification of distributions to shareholders to reflect
the differences between financial statement amounts and distributions determined
in accordance with income tax  regulations.  Accordingly,  during the year ended
July 31,  1998,  amounts  have  been  reclassified  to  reflect  a  decrease  in
undistributed net investment income of $1,722,382, a decrease in accumulated net
realized loss on investments of $124,880,  and an increase in paid-in capital of
$1,597,502.

- --------------------------------------------------------------------------------
OTHER. Investment transactions are accounted for on the date the investments are
purchased or sold (trade date).  Original issue discount on securities purchased
is amortized  over the life of the  respective  securities,  in accordance  with
federal  income tax  requirements.  As of November 4, 1997,  in order to conform
book and tax bases,  the Fund began  amortization  of premiums on securities for
book  purposes.  Such  cumulative  change  was  limited  to  a  reclassification
adjustment and had no impact on net assets or total  increase  (decrease) in net
assets.  Accordingly,  during the year ended July 31,  1998,  amounts  have been
reclassified   to  reflect  an  increase  in  net  unrealized   appreciation  on
investments of $2,700,126. Paid-in capital was decreased by the same amount. For
bonds  acquired  after April 30,  1993,  on  disposition  or  maturity,  taxable
ordinary  income is  recognized  to the  extent of the  lesser of gain or market
discount  that would have accrued over the holding  period.  Realized  gains and
losses  on  investments  and  unrealized   appreciation   and  depreciation  are
determined on an identified cost basis, which is the same basis used for federal
income tax purposes.

       The Fund concentrates its investments in California and,  therefore,  may
have more credit risks related to the economic  conditions of California  than a
portfolio with a broader geographical diversification.

       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.

$201,896.

4. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Management  fees paid to the  Manager  were in  accordance  with the  investment
advisory  agreement with the Fund which provides for a fee of 0.60% 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 in excess of $1 billion.

                  For the year ended July 31, 1998,  commissions  (sales charges
paid by  investors)  on  sales  of Class A  shares  totaled  $922,528,  of which
$141,083 was retained by OppenheimerFunds Distributor, Inc. (OFDI), a subsidiary
of the Manager,  as general  distributor,  and by an  affiliated  broker/dealer.
Sales charges advanced to  broker/dealers by OFDI on sales of the Fund's Class B
and  Class C shares  totaled  $1,607,116  and  $66,159,  respectively,  of which
$24,983  and  $1,207,  respectively,  was paid to an  affiliated  broker/dealer.
During the year ended July 31, 1998,  OFDI received  contingent  deferred  sales
charges of $264,900 and $5,565,  respectively,  upon  redemption  of Class B and
Class C shares as reimbursement  for sales  commissions  advanced by OFDI at the
time of sale of such shares.

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

                  The Fund has  adopted  a  Service  Plan for  Class A shares to
reimburse  OFDI for a  portion  of its costs  incurred  in  connection  with the
personal  service and  maintenance  of  shareholder  accounts  that hold Class A
shares.  Reimbursement  is made  quarterly at an annual rate that may not exceed
0.25% of the average annual net assets of Class A shares of the Fund.  OFDI uses
the  service  fee to  reimburse  brokers,  dealers,  banks and  other  financial
institutions  quarterly  for  providing  personal  service  and  maintenance  of
accounts of their customers that hold Class A shares. During the year ended July
31, 1998, OFDI paid $21,461 to an affiliated  broker/dealer as reimbursement for
Class A personal service and maintenance expenses.

                   33 Oppenheimer California Municipal Fund
<PAGE>
================================================================================
4. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES (continued)


The Fund has  adopted  Distribution  and  Service  Plans for Class B and Class C
shares  to  compensate  OFDI for its costs in  distributing  Class B and Class C
shares and  servicing  accounts.  Under the Plans,  the Fund pays OFDI an annual
asset-based  sales  charge of 0.75% per year on Class B and Class C shares,  for
its  services  rendered in  distributing  Class B and Class C shares.  OFDI also
receives a service fee of 0.25% per year to  compensate  dealers  for  providing
personal services for accounts that hold Class B and Class C shares. Each fee is
computed  on the  average  annual  net  assets  of  Class B or  Class C  shares,
determined as of the close of each regular  business day.  During the year ended
July 31,  1998,  OFDI paid $2,065 and  $2,722,  respectively,  to an  affiliated
broker/dealer  as  compensation  for Class B and Class C  personal  service  and
maintenance  expenses  and  retained  $832,617  and  $59,727,  respectively,  as
compensation for Class B and Class C sales commissions and service fee advances,
as well as financing  costs.  If the Plans are terminated by the Fund, the Board
of Trustees  may allow the Fund to continue  payments of the  asset-based  sales
charge  to  OFDI  for  certain  expenses  it  incurred  before  the  Plans  were
terminated.  At July  31,  1998,  OFDI  had  incurred  excess  distribution  and
servicing costs of $3,588,025 for Class B and $138,504 for Class C.


================================================================================
5. FUTURES CONTRACTS

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

                  The Fund  generally  sells futures  contracts to hedge against
increases in interest  rates and the resulting  negative  effect on the value of
fixed rate portfolio securities. The Fund may also purchase futures contracts to
gain  exposure to changes in  interest  rates as it may be more  efficient  than
actually buying fixed income securities.

                  Upon entering into a futures contract, the Fund is required to
deposit  either  cash or  securities  (initial  margin) in an amount  equal to a
certain percentage of the contract value. Subsequent payments (variation margin)
are made or received by the Fund each day.  The  variation  margin  payments are
equal to the daily changes in the contract  value and are recorded as unrealized
gains and losses.  The Fund recognizes a realized gain or loss when the contract
is closed or expires.

                   34 Oppenheimer California Municipal Fund
<PAGE>
================================================================================
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  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.

At July 31, 1998, 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 31, 1998.

                Descriptions of Municipal Bond Ratings Categories
                        Of Principal Rating Agencies


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.

         OppenheimerFunds Special Sales Charge Arrangements and Waivers


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

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

     For  the  purposes  of  some  of the  waivers  described  below  and in the
     Prospectus  and  Statement  of  Additional  Information  of the  applicable
     Oppenheimer funds, the term "Retirement Plan" refers to the following types
     of  plans:

     (1) plans qualified under Sections 401(a) or 401(k) of the Internal Revenue
     Code,

(2)       non-qualified deferred compensation plans,
(3)       employee benefit plans1
(4)       Group Retirement Plans2
(5)       403(b)(7) custodial plan accounts
(6)       SEP-IRAs, SARSEPs or SIMPLE plans

     The  interpretation of these provisions as to the applicability of a waiver
in a particular  case is determined  solely by the  Distributor  or the Transfer
Agent of the fund.  These  waivers  and special  arrangements  may be amended or
terminated at any time by the applicable  Fund and/or the  Distributor.  Waivers
that apply at the time shares are redeemed must be requested by the  shareholder
and/or dealer in the redemption request. 

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

     1. An "employee benefit plan" means any plan or arrangement, whether or not
     it is  "qualified"  under the Internal  Revenue  Code,  under which Class A
     shares of an  Oppenheimer  fund or funds are  purchased  by a fiduciary  or
     other  administrator for the account of participants who are employees of a
     single employer or of affiliated employers. These may include, for example,
     medical savings  accounts,  payroll  deduction plans or similar plans.  The
     fund  accounts  must  be  registered  in  the  name  of  the  fiduciary  or
     administrator  purchasing the shares for the benefit of participants in the
     plan.

  2. The term  "Group  Retirement  Plan"  means  any  qualified  or
non-qualified   retirement   plan  for  employees  of  a  corporation   or  sole
proprietorship,  members and employees of a partnership  or association or other
organized  group of persons (the members of which may include other groups),  if
the group has made special  arrangements with the Distributor and all members of
the group  participating  in (or who are  eligible to  participate  in) the plan
purchase  Class A  shares  of an  Oppenheimer  fund or  funds  through  a single
investment  dealer,  broker or other  financial  institution  designated  by the
group. Such plans include 457 plans, SEP-IRAs,  SARSEPs, SIMPLE plans and 403(b)
plans other than plans for public school  employees.  The term "Group Retirement
Plan"  also  includes  qualified  retirement  plans and  non-qualified  deferred
compensation  plans and IRAs that purchase Class A shares of an Oppenheimer fund
or  funds  through  a  single  investment  dealer,  broker  or  other  financial
institution  that has made special  arrangements  with the Distributor  enabling
those  plans to  purchase  Class A shares at net asset  value but subject to the
Class A contingent deferred sales charge.

Applicability of Class A Contingent Deferred Sales Charges in Certain Cases


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

         There is no initial  sales charge on purchases of Class A shares of any
of the Oppenheimer funds in the cases listed below. However, these purchases may
be subject to the Class A contingent deferred sales charge if redeemed within 18
months of the end of the calendar month of their  purchase,  as described in the
Prospectus (unless a waiver described  elsewhere in this Appendix applies to the
redemption).  Additionally,  on these  purchases  the  Distributor  will pay the
applicable  commission  described  in the  Prospectus  under "Class A Contingent
Deferred Sales Charge":  o Purchases of Class A shares aggregating $1 million or
more. o Purchases by a Retirement Plan that: 

(1) buys shares costing $500,000 or
more, or

     (2) has, at the time of  purchase,  100 or more  eligible  participants  or
     total plan assets of $500,000 or more, or

     (3)  certifies  to the  Distributor  that it  projects  to have annual plan
     purchases of $200,000 or more.

     o Purchases by an OppenheimerFunds-sponsored Rollover IRA, if the purchases
     are made:

     (1) through a broker,  dealer,  bank or registered  investment adviser that
     has made special arrangements with the Distributor for those purchases, or

     (2) by a direct rollover of a distribution from a qualified Retirement Plan
     if the  administrator of that Plan has made special  arrangements  with the
     Distributor for those purchases.

     o  Purchases  of Class A shares by  Retirement  Plans  that have any of the
     following record-keeping arrangements: 

     (1) The record keeping is performed by Merrill Lynch Pierce Fenner & Smith,
     Inc.  ("Merrill Lynch") on a daily valuation basis for the Retirement Plan.
     On the date the plan sponsor  signs the  record-keeping  service  agreement
     with  Merrill  Lynch,  the Plan must have $3  million or more of its assets
     invested  in (a)  mutual  funds,  other  than  those  advised or managed by
     Merrill Lynch Asset  Management,  L.P.  ("MLAM"),  that are made  available
     under a Service  Agreement  between  Merrill  Lynch and the  mutual  fund's
     principal  underwriter or distributor,  and (b) funds advised or managed by
     MLAM (the funds  described  in (a) and (b) are  referred to as  "Applicable
     Investments").

     (2) The record  keeping for the  Retirement  Plan is  performed  on a daily
     valuation  basis by a record  keeper whose  services  are provided  under a
     contract or arrangement  between the Retirement  Plan and Merrill Lynch. On
     the date the plan sponsor signs the record keeping  service  agreement with
     Merrill  Lynch,  the  Plan  must  have $3  million  or  more of its  assets
     (excluding  assets  invested in money market funds)  invested in Applicable
     Investments.

     (3) The record  keeping for a  Retirement  Plan is handled  under a service
     agreement  with Merrill  Lynch and on the date the plan sponsor  signs that
     agreement,  the Plan has 500 or more eligible  employees (as  determined by
     the Merrill Lynch plan conversion manager).

Account,  Connecticut  Mutual Growth  Account,  Connecticut  Mutual Total Return
Account,  CMIA LifeSpan Capital  Appreciation  Account,  CMIA LifeSpan  Balanced

Prior Class A CDSC and Class A Sales Charge Waivers

         n Class A Contingent Deferred Sales Charge.  Certain  shareholders of a
Fund and the other Former  Connecticut  Mutual Funds are entitled to continue to
make additional purchases of Class A shares at net asset value without a Class A
initial  sales  charge,  but subject to the Class A  contingent  deferred  sales
charge that was in effect  prior to March 18,  1996 (the "prior  Class A CDSC").
Under the prior Class A CDSC,  if any of those  shares are  redeemed  within one
year of purchase, they will be assessed a 1% contingent deferred sales charge on
an amount equal to the current  market value or the original  purchase  price of
the shares  sold,  whichever  is smaller  (in such  redemptions,  any shares not
subject to the prior Class A CDSC will be redeemed first).

         Those shareholders who are eligible for the prior Class A CDSC are:

(1)           persons  whose  purchases  of Class A shares  of a Fund and  other
              Former  Connecticut  Mutual Funds were $500,000 prior to March 18,
              1996, as a result of direct purchases or purchases pursuant to the
              Fund's policies on Combined  Purchases or Rights of  Accumulation,
              who  still  hold  those  shares  in  that  Fund  or  other  Former
              Connecticut Mutual Funds, and

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

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

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

     (1) any purchaser,  provided the total initial amount  invested in the Fund
     or any one or more of the Former  Connecticut Mutual Funds totaled $500,000
     or more,  including  investments  made pursuant to the Combined  Purchases,
     Statement of Intention and Rights of Accumulation features available at the
     time of the initial  purchase and such  investment  is still held in one or
     more of the Former  Connecticut Mutual Funds or a Fund into which such Fund
     merged;

     (2) any  participant in a qualified  plan,  provided that the total initial
     amount  invested  by the plan in the Fund or any one or more of the  Former
     Connecticut  Mutual Funds  totaled  $500,000 or more;  

     (3)  Directors  of the  Fund or any one or more of the  Former  Connecticut
     Mutual Funds and members of their immediate families;

     (4) employee  benefit  plans  sponsored  by  Connecticut  Mutual  Financial
     Services,  L.L.C. ("CMFS"), the prior distributor of the Former Connecticut
     Mutual Funds, and its affiliated companies;

     (5) one or more  members of a group of at least 1,000  persons (and persons
     who are retirees from such group) engaged in a common business, profession,
     civic or charitable  endeavor or other activity,  and the spouses and minor
     dependent children of such persons, pursuant to a marketing program between
     CMFS and such group; and

     (6) an  institution  acting as a fiduciary  on behalf of an  individual  or
     individuals,   if  such   institution  was  directly   compensated  by  the
     individual(s)  for  recommending  the purchase of the shares of the Fund or
     any  one or more of the  Former  Connecticut  Mutual  Funds,  provided  the
     institution had an agreement with CMFS.

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

         Additionally, Class A shares of a Fund may be purchased without a sales
charge by any holder of a variable  annuity contract issued in New York State by
Connecticut  Mutual Life Insurance Company through the Panorama Separate Account

fund a qualified plan, if that holder  exchanges the variable  annuity  contract
proceeds to buy Class A shares of the Fund.

above,  the contingent  deferred sales charge will be waived for  redemptions of
Class A and Class B shares of a Fund and  exchanges of Class A or Class B shares
of a Fund into  Class A or Class B shares of a Former  Connecticut  Mutual  Fund
provided  that  the  Class A or Class B shares  of the  Fund to be  redeemed  or

exchange from an  Oppenheimer  fund that was a Former  Connecticut  Mutual Fund.

     9/14/98, and incorporated herein by reference.

     -- Powers of Attorney (including Certified Board resolutions):  (Bridget A.
     Macaskill) Previously filed with Registrant's  Post-Effective Amendment No.
     13 (April 20, 1996);  others  previously  filed (all other  Trustees)  with
     Registrant's   Post-Effective   Amendment   No.  7  (March  1,   1994)  and
     incorporated herein by reference.

Item 24.  Persons Controlled by or Under Common Control with the Fund

None.

Item 25.  Indemnification

         Reference is made to the provisions of Article  Seventh of Registrant's
Amended  and  Restated  Declaration  of  Trust  filed as  Exhibit  23(a) to this
Registration Statement, and incorporated herein by reference.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to trustees,  officers and  controlling  persons of
Registrant  pursuant to the foregoing  provisions or otherwise,  Registrant  has
been advised that in the opinion of the Securities and Exchange  Commission such
indemnification  is against  public policy as expressed in the Securities Act of
1933  and  is,  therefore,   unenforceable.  In  the  event  that  a  claim  for
indemnification  against such liabilities  (other than the payment by Registrant
of expenses  incurred  or paid by a trustee,  officer or  controlling  person of
Registrant  in the  successful  defense of any action,  suit or  proceeding)  is
asserted by such trustee, officer or controlling person, Registrant will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification  by it is  against  public  policy  as  expressed  in  the
Securities  Act of 1933 and will be governed by the final  adjudication  of such
issue.


Item 26.  Business and Other Connections of the Investment Adviser

(a) OppenheimerFunds,  Inc. is the investment adviser of the Registrant;  it and
certain subsidiaries and affiliates act in the same capacity to other registered

26(b) below.

(b) There is set forth below  information as to any other business,  profession,
vocation  or  employment  of a  substantial  nature in which  each  officer  and

To the Board of Trustees:

Oppenheimer  Management Corporation ("OMC") herewith purchases 10,493,179 shares
of Oppenheimer  California  Tax-Exempt  Fund for an aggregate  purchase price of
$100,000.

In connection with such purchases, OMC represents that such purchase is made for
investment purposes by OMC without any present intention of redeeming or selling
such shares; and furthermore,  that OMC agrees to advance the organizational and
start-up  expenses  of the  Corporation  and in that  regard  agrees  that  such
advances  for  such  start-up  expenses  shall  be  reimbursed  to  OMC  by  the
Corporation  when the  Corporation  reaches  $10  million  in net  assets.  Such
deferred  organization  expenses  will be  amortized to expense by the Fund on a
straight line basis over a five year period that commences on the effective date
the  initial  shares  of the  Fund  are  redeemed  by  OMC  prior  to  the  full
amortization  of the  organization  expenses,  the  redemption  proceeds will be
reduced  by the then  unamortized  organization  costs in the same  ratio as the
number of shares  redeemed bears to the number of initial shares  outstanding at
the time of such redemption.

                                                     Very truly yours,

                                            OPPENHEIMER MANAGEMENT CORPORATION

                              DISTRIBUTION AND SERVICE PLAN AND AGREEMENT

                                                        With

                                         OppenheimerFunds Distributor, Inc.

                                                For Class B Shares of

                                        Oppenheimer California Municipal Fund

This  Amended and Restated  Distribution  and Service  Plan and  Agreement  (the
"Plan")  is  dated  as of  the  12th  day of  February,  1998,  by  and  between
Oppenheimer   California   Municipal  Fund  (the  "Fund")  and  OppenheimerFunds
Distributor, Inc. (the "Distributor").

1. The Plan. This Plan is the Fund's written  distribution  and service plan for
Class B shares of the Fund (the "Shares"),  contemplated by Rule 12b-1 as it may
be amended from time to time (the "Rule")  under the  Investment  Company Act of
1940  (the  "1940  Act"),  pursuant  to  which  the  Fund  will  compensate  the
Distributor for its services in connection with the distribution of Shares,  and
the personal  service and  maintenance of shareholder  accounts that hold Shares
("Accounts").  The Fund may act as  distributor of securities of which it is the
issuer, pursuant to the Rule, according to the terms of this Plan. The terms and
provisions of this Plan shall be interpreted and defined in a manner  consistent
with the  provisions  and  definitions  contained in (i) the 1940 Act,  (ii) the
Rule,  (iii)  Rule 2830 of the  Conduct  Rules of the  National  Association  of
Securities Dealers,  Inc., or any amendment or successor to such rule (the "NASD
Conduct    Rules")   and   (iv)   any    conditions    pertaining    either   to
distribution-related  expenses or to a plan of distribution to which the Fund is
subject under any order on which the Fund relies, issued at any time by the U.S.
Securities and Exchange Commission ("SEC").

2.  Definitions.  As used in this  Plan,  the  following  terms  shall  have the
following meanings:

         (a) "Recipient" shall mean any broker,  dealer, bank or other person or
entity which: (i) has rendered  assistance  (whether direct,  administrative  or
both) in the  distribution  of Shares  or has  provided  administrative  support
services  with  respect  to  Shares  held by  Customers  (defined  below) of the
Recipient;  (ii) shall furnish the Distributor (on behalf of the Fund) with such
information as the Distributor shall reasonably request to answer such questions
as may arise  concerning the sale of Shares;  and (iii) has been selected by the
Distributor to receive payments under the Plan.

         (b)  "Independent  Trustees" shall mean the members of the Fund's Board
of Trustees who are not "interested persons" (as defined in the 1940 Act) of the
Fund and who have no direct or indirect  financial  interest in the operation of
this Plan or in any agreement relating to this Plan.

         (c)  "Customers"  shall  mean  such  brokerage  or other  customers  or
investment advisory or other clients of a Recipient, and/or accounts as to which
such Recipient  provides  administrative  support  services or is a custodian or
other fiduciary.

         (d) "Qualified  Holdings"  shall mean, as to any Recipient,  all Shares
owned beneficially or of record by: (i) such Recipient, or (ii) such Recipient's
Customers,  but in no event shall any such  Shares be deemed  owned by more than
one  Recipient for purposes of this Plan. In the event that more than one person
or entity would  otherwise  qualify as  Recipients  as to the same  Shares,  the
Recipient which is the dealer of record on the Fund's books as determined by the
Distributor shall be deemed the Recipient as to such Shares for purposes of this
Plan.

3.    Payments for Distribution Assistance and Administrative Support Services.

         (a) Payments to the Distributor.  In consideration of the payments made
by the Fund to the Distributor  under this Plan, the  Distributor  shall provide
administrative  support  services and  distribution  assistance  services to the
Fund. Such services include distribution  assistance and administrative  support
services  rendered in connection with Shares (1) sold in purchase  transactions,
(2) issued in exchange  for shares of another  investment  company for which the
Distributor serves as distributor or sub-distributor,  or (3) issued pursuant to
a plan of  reorganization  to which the Fund is a party.  If the Board  believes
that the Distributor may not be rendering appropriate distribution assistance or
administrative  support services in connection with the sale of Shares, then the
Distributor, at the request of the Board, shall provide the Board with a written
report  or other  information  to  verify  that  the  Distributor  is  providing
appropriate  services in this regard. For such services,  the Fund will make the
following payments to the Distributor:

                   (i)  Administrative  Support Services Fees. Within forty-five
(45) days of the end of each  calendar  quarter,  the Fund will make payments in
the aggregate amount of 0.0625% (0.25% on an annual basis) of the average during
that calendar quarter of the aggregate net asset value of the Shares computed as
of the close of each business day (the "Service Fee"). Such Service Fee payments
received  from  the  Fund  will   compensate  the   Distributor   for  providing
administrative  support  services with respect to Accounts.  The  administrative
support  services in  connection  with  Accounts may  include,  but shall not be
limited to, the  administrative  support services that a Recipient may render as
described in Section 3(b)(i) below.

                  (ii) Distribution  Assistance Fees (Asset-Based Sales Charge).
Within ten (10) days of the end of each  month,  the Fund will make  payments in
the aggregate amount of 0.0625% (0.75% on an annual basis) of the average during
the month of the aggregate net asset value of Shares computed as of the close of
each business day (the "Asset-Based Sales Charge")  outstanding for no more than
six years (the "Maximum Holding Period"). Such Asset-Based Sales Charge payments
received  from  the  Fund  will   compensate  the   Distributor   for  providing
distribution assistance in connection with the sale of Shares.

                  The distribution  assistance to be rendered by the Distributor
in  connection  with the Shares may  include,  but shall not be limited  to, the
following:  (i) paying sales  commissions to any broker,  dealer,  bank or other
person or entity that sells Shares,  and/or paying such persons "Advance Service
Fee Payments" (as defined below) in advance of, and/or in amounts  greater than,
the  amount  provided  for in  Section  3(b)  of  this  Agreement;  (ii)  paying
compensation  to and  expenses  of  personnel  of the  Distributor  who  support
distribution  of Shares by Recipients;  (iii)  obtaining  financing or providing
such financing from its own  resources,  or from an affiliate,  for the interest
and other borrowing costs of the Distributor's unreimbursed expenses incurred in
rendering  distribution  assistance and  administrative  support services to the
Fund;  and (iv)  paying  other  direct  distribution  costs,  including  without
limitation the costs of sales  literature,  advertising and prospectuses  (other
than  those  prospectuses  furnished  to current  holders  of the Fund's  shares
("Shareholders")) and state "blue sky" registration expenses.

         (b) Payments to Recipients.  The  Distributor  is authorized  under the
Plan  to  pay  Recipients  (1)   distribution   assistance  fees  for  rendering
distribution assistance in connection with the sale of Shares and/or (2) service
fees for  rendering  administrative  support  services with respect to Accounts.
However, no such payments shall be made to any Recipient for any such quarter in
which its Qualified Holdings do not equal or exceed, at the end of such quarter,
the minimum amount ("Minimum Qualified Holdings"),  if any, that may be set from
time to time by a majority of the Independent Trustees. All fee payments made by
the  Distributor  hereunder  are subject to reduction or  chargeback so that the
aggregate  service fee payments  and Advance  Service Fee Payments do not exceed
the limits on payments to  Recipients  that are, or may be,  imposed by the NASD
Conduct Rules. The Distributor may make Plan payments to any "affiliated person"
(as  defined  in the 1940  Act) of the  Distributor  if such  affiliated  person
qualifies as a Recipient or retain such payments if the Distributor qualifies as
a Recipient.


<PAGE>


                  (i)  Service  Fee.  In  consideration  of  the  administrative
support  services  provided  by a  Recipient  during  a  calendar  quarter,  the
Distributor shall make service fee payments to that Recipient quarterly,  within
forty-five  (45)  days of the end of each  calendar  quarter,  at a rate  not to
exceed  0.0625%  (0.25% on an annual  basis) of the average  during the calendar
quarter of the aggregate net asset value of Shares,  computed as of the close of
each business day,  constituting  Qualified  Holdings owned  beneficially  or of
record  by the  Recipient  or by its  Customers  for a period  of more  than the
minimum period (the "Minimum Holding Period"), if any, that may be set from time
to time by a majority of the Independent Trustees.

                  Alternatively,  the Distributor may, at its sole option,  make
the following service fee payments to any Recipient quarterly, within forty-five
(45)  days  of the  end of each  calendar  quarter:  (i)  "Advance  Service  Fee
Payments"  at a rate not to exceed  0.25% of the  average  during  the  calendar
quarter of the aggregate net asset value of Shares,  computed as of the close of
business on the day such Shares are sold,  constituting Qualified Holdings, sold
by the Recipient during that quarter and owned  beneficially or of record by the
Recipient or by its  Customers,  plus (ii) service fee payments at a rate not to
exceed  0.0625%  (0.25% on an annual  basis) of the average  during the calendar
quarter of the aggregate net asset value of Shares,  computed as of the close of
each business day,  constituting  Qualified  Holdings owned  beneficially  or of
record by the  Recipient or by its  Customers  for a period of more than one (1)
year. At the Distributor's  sole option, the Advance Service Fee Payments may be
made more often than quarterly, and sooner than the end of the calendar quarter.
In the event Shares are  redeemed  less than one year after the date such Shares
were sold,  the  Recipient  is obligated  to and will repay the  Distributor  on
demand a pro rata portion of such  Advance  Service Fee  Payments,  based on the
ratio of the time such Shares were held to one (1) year.

                  The   administrative   support  services  to  be  rendered  by
Recipients in connection with the Accounts may include, but shall not be limited
to, the following: answering routine inquiries concerning the Fund, assisting in
the  establishment  and  maintenance of accounts or sub-accounts in the Fund and
processing Share redemption transactions, making the Fund's investment plans and
dividend  payment options  available,  and providing such other  information and
services  in  connection  with the  rendering  of personal  services  and/or the
maintenance of Accounts, as the Distributor or the Fund may reasonably request.

                  (ii) Distribution  Assistance Fees (Asset-Based  Sales Charge)
Payments.  In its sole  discretion  and  irrespective  of whichever  alternative
method  of  making  service  fee  payments  to  Recipients  is  selected  by the
Distributor,  in addition the Distributor may make  distribution  assistance fee
payments to a Recipient quarterly,  within forty-five (45) days after the end of
each  calendar  quarter,  at a rate not to  exceed  0.1875%  (0.75% on an annual
basis) of the average  during the calendar  quarter of the  aggregate  net asset
value of Shares  computed  as of the  close of each  business  day  constituting
Qualified  Holdings  owned  beneficially  or of record by the  Recipient  or its
Customers  for no more  than  six  years  and for any  minimum  period  that the
Distributor  may establish.  Distribution  assistance fee payments shall be made
only to Recipients that are registered  with the SEC as a  broker-dealer  or are
exempt from registration.

                  The  distribution  assistance to be rendered by the Recipients
in connection with the sale of Shares may include,  but shall not be limited to,
the following:  distributing  sales literature and prospectuses other than those
furnished to current Shareholders, providing compensation to and paying expenses
of  personnel of the  Recipient  who support the  distribution  of Shares by the
Recipient,  and providing such other information and services in connection with
the  distribution  of  Shares  as the  Distributor  or the Fund  may  reasonably
request.



<PAGE>


         (c) A majority of the Independent Trustees may at any time or from time
to time increase or decrease the rate of fees to be paid to the  Distributor  or
to any Recipient, but not to exceed the rates set forth above, and/or direct the
Distributor  to increase or decrease  the Maximum  Holding  Period,  any Minimum
Holding Period or any Minimum Qualified  Holdings.  The Distributor shall notify
all Recipients of any Minimum  Qualified  Holdings,  Maximum  Holding Period and
Minimum Holding Period that are  established and the rate of payments  hereunder
applicable to  Recipients,  and shall provide each Recipient with written notice
within thirty (30) days after any change in these provisions.  Inclusion of such
provisions or a change in such provisions in a revised current  prospectus shall
constitute sufficient notice.

         (d) The  Service  Fee and the  Asset-Based  Sales  Charge on Shares are
subject to reduction or  elimination  under the limits to which the  Distributor
is, or may become, subject under the NASD Conduct Rules.

         (e) Under the Plan,  payments  may also be made to  Recipients:  (i) by
OppenheimerFunds, Inc. ("OFI") from its own resources (which may include profits
derived  from  the  advisory  fee it  receives  from the  Fund),  or (ii) by the
Distributor  (a subsidiary of OFI),  from its own  resources,  from  Asset-Based
Sales Charge payments or from the proceeds of its borrowings, in either case, in
the discretion of OFI or the Distributor, respectively.

         (f)  Recipients  are  intended to have  certain  rights as  third-party
beneficiaries  under this Plan,  subject to the  limitations set forth below. It
may be  presumed  that a  Recipient  has  provided  distribution  assistance  or
administrative  support services qualifying for payment under the Plan if it has
Qualified  Holdings of Shares that entitle it to payments under the Plan. In the
event that  either the  Distributor  or the Board  should have reason to believe
that,  notwithstanding the level of Qualified  Holdings,  a Recipient may not be
rendering  appropriate  distribution  assistance in connection  with the sale of
Shares or administrative support services for Accounts, then the Distributor, at
the  request of the Board,  shall  require  the  Recipient  to provide a written
report  or  other  information  to  verify  that  said  Recipient  is  providing
appropriate  distribution  assistance  and/or  services in this  regard.  If the
Distributor or the Board of Trustees still is not satisfied after the receipt of
such report,  either may take  appropriate  steps to terminate  the  Recipient's
status  as  such  under  the  Plan,  whereupon  such  Recipient's  rights  as  a
third-party  beneficiary  hereunder  shall  terminate.  Additionally,  in  their
discretion, a majority of the Fund's Independent Trustees at any time may remove
any broker,  dealer,  bank or other person or entity as a Recipient,  where upon
such  person's or entity's  rights as a  third-party  beneficiary  hereof  shall
terminate.  Notwithstanding any other provision of this Plan, this Plan does not
obligate or in any way make the Fund liable to make any  payment  whatsoever  to
any person or entity other than directly to the Distributor. The Distributor has
no obligation  to pay any Service Fees or  Distribution  Assistance  Fees to any
Recipient  if the  Distributor  has not  received  payment  of  Service  Fees or
Distribution Assistance Fees from the Fund.

4.  Selection  and  Nomination  of Trustees.  While this Plan is in effect,  the
selection  and  nomination  of  persons to be  Trustees  of the Fund who are not
"interested persons" of the Fund  ("Disinterested  Trustees") shall be committed
to the discretion of the incumbent Disinterested Trustees.  Nothing herein shall
prevent the incumbent  Disinterested  Trustees from  soliciting the views or the
involvement  of others in such  selection  or  nominations  as long as the final
decision on any such  selection and  nomination is approved by a majority of the
incumbent Disinterested Trustees.

5.  Reports.  While  this Plan is in  effect,  the  Treasurer  of the Fund shall
provide written reports to the Fund's Board for its review, detailing the amount
of all payments made under this Plan and the purpose for which the payments were
made.  The reports  shall be  provided  quarterly,  and shall state  whether all
provisions of Section 3 of this Plan have been complied with.

6. Related  Agreements.  Any agreement  related to this Plan shall be in writing
and shall  provide  that:  (i) such  agreement  may be  terminated  at any time,
without  payment  of any  penalty,  by a vote of a majority  of the  Independent
Trustees  or by a vote of the  holders of a  "majority"  (as defined in the 1940
Act) of the Fund's  outstanding  Class B voting  shares;  (ii) such  termination
shall be on not more than sixty days'  written  notice to any other party to the
agreement;  (iii) such agreement shall  automatically  terminate in the event of
its "assignment" (as defined in the 1940 Act); (iv) such agreement shall go into
effect when approved by a vote of the Board and its Independent Trustees cast in
person at a meeting called for the purpose of voting on such agreement;  and (v)
such agreement shall,  unless terminated as herein provided,  continue in effect
from year to year only so long as such  continuance is specifically  approved at
least  annually  by a vote of the Board  and its  Independent  Trustees  cast in
person at a meeting called for the purpose of voting on such continuance.

7.  Effectiveness,  Continuation,  Termination  and Amendment.  This Amended and
Restated  Plan has been  approved by a vote of the Board and of the  Independent
Trustees and replaces the Fund's prior Distribution and Service Plan for Class B
Shares.  Unless terminated as hereinafter  provided, it shall continue in effect
until renewed by the Board in accordance  with the Rule and thereafter from year
to  year  or as the  Board  may  otherwise  determine  but  only so long as such
continuance  is  specifically  approved at least annually by a vote of the Board
and its Independent  Trustees cast in person at a meeting called for the purpose
of voting on such continuance.

         This Plan may not be  amended  to  increase  materially  the  amount of
payments  to  be  made  under  this  Plan,  without  approval  of  the  Class  B
Shareholders at a meeting called for that purpose,  and all material  amendments
must be approved by a vote of the Board and of the Independent Trustees.

          This Plan may be  terminated  at any time by vote of a majority of the
Independent  Trustees or by the vote of the holders of a "majority"  (as defined
in the 1940 Act) of the Fund's  outstanding  Class B voting shares. In the event
of such  termination,  the Board and its  Independent  Trustees shall  determine
whether the  Distributor  shall be entitled to payment from the Fund of all or a
portion of the Service  Fee and/or the  Asset-Based  Sales  Charge in respect of
Shares sold prior to the effective date of such termination.

8. Disclaimer of Shareholder and Trustee Liability.  The Distributor understands
that the  obligations  of the Fund  under  this  Plan are not  binding  upon any
Trustee or  shareholder of the Fund  personally,  but bind only the Fund and the
Fund's property. The Distributor represents that it has notice of the provisions
of the  Declaration  of Trust of the Fund  disclaiming  shareholder  and Trustee
liability for acts or obligations of the Fund.

Class C shares of the Fund (the "Shares"),  contemplated by Rule 12b-1 as it may
be amended from time to time (the "Rule")  under the  Investment  Company Act of
1940  (the  "1940  Act"),  pursuant  to  which  the  Fund  will  compensate  the

         (a) "Recipient" shall mean any broker,  dealer, bank or other person or

3.    Payments for Distribution Assistance and Administrative Support Services.

         (a) Payments to the Distributor.  In consideration of the payments made
by the Fund to the Distributor  under this Plan, the  Distributor  shall provide
administrative  support  services and  distribution  services to the Fund.  Such
services include  distribution  assistance and  administrative  support services
rendered in connection with Shares (1) sold in purchase transactions, (2) issued
in exchange for shares of another  investment  company for which the Distributor
serves as distributor or  sub-distributor,  or (3) issued  pursuant to a plan of
reorganization  to which  the Fund is a party.  If the Board  believes  that the
Distributor  may  not  be  rendering  appropriate   distribution  assistance  or
administrative  support services in connection with the sale of Shares, then the
Distributor, at the request of the Board, shall provide the Board with a written
report  or other  information  to  verify  that  the  Distributor  is  providing
appropriate  services in this regard. For such services,  the Fund will make the
following payments to the Distributor:

                  (i)  Administrative  Support Service Fees.  Within  forty-five
(45) days of the end of each  calendar  quarter,  the Fund will make payments in
the aggregate amount of 0.0625% (0.25% on an annual basis) of the average during
that calendar quarter of the aggregate net asset value of the Shares computed as
of the close of each business day (the "Service Fee"). Such Service Fee payments
received  from  the  Fund  will   compensate  the   Distributor   for  providing
administrative  support  services with respect to Accounts.  The  administrative
support  services in  connection  with  Accounts may  include,  but shall not be
limited to, the  administrative  support services that a Recipient may render as
described in Section 3(b)(i) below.

                  (ii) Distribution  Assistance Fees (Asset-Based Sales Charge).
Within ten (10) days of the end of each  month,  the Fund will make  payments in
the aggregate amount of 0.0625% (0.75% on an annual basis) of the average during
the month of the aggregate net asset value of Shares computed as of the close of
each business day (the  "Asset-Based  Sales  Charge").  Such  Asset-Based  Sales
Charge  payments  received from the Fund will  compensate  the  Distributor  for
providing distribution assistance in connection with the sale of Shares.

         The distribution  assistance services to be rendered by the Distributor
in  connection  with the Shares may  include,  but shall not be limited  to, the
following:  (i) paying sales  commissions to any broker,  dealer,  bank or other
person or entity that sells Shares,  and/or paying such persons "Advance Service
Fee Payments" (as defined below) in advance of, and/or in amounts  greater than,
the  amount  provided  for in  Section  3(b)  of  this  Agreement;  (ii)  paying
compensation  to and  expenses  of  personnel  of the  Distributor  who  support
distribution  of Shares by Recipients;  (iii)  obtaining  financing or providing
such financing from its own  resources,  or from an affiliate,  for the interest
and other borrowing costs of the Distributor's unreimbursed expenses incurred in
rendering  distribution  assistance and  administrative  support services to the
Fund;  and (iv)  paying  other  direct  distribution  costs,  including  without
limitation the costs of sales  literature,  advertising and prospectuses  (other
than  those  prospectuses  furnished  to current  holders  of the Fund's  shares
("Shareholders")) and state "blue sky" registration expenses.

         (b) Payments to Recipients.  The  Distributor  is authorized  under the
Plan  to  pay  Recipients  (1)   distribution   assistance  fees  for  rendering
distribution assistance in connection with the sale of Shares and/or (2) service
fees for  rendering  administrative  support  services with respect to Accounts.
However,  no such  payments  shall be made to any  Recipient  for any quarter in
which its Qualified Holdings do not equal or exceed, at the end of such quarter,
the minimum amount ("Minimum Qualified Holdings"),  if any, that may be set from
time to time by a majority of the Independent Trustees. All fee payments made by
the  Distributor  hereunder  are subject to reduction or  chargeback so that the
aggregate  service fee payments  and Advance  Service Fee Payments do not exceed
the limits on payments to  Recipients  that are, or may be,  imposed by the NASD
Conduct Rules. The Distributor may make Plan payments to any "affiliated person"
(as  defined  in the 1940  Act) of the  Distributor  if such  affiliated  person
qualifies as a Recipient or retain such payments if the Distributor qualifies as
a Recipient.



<PAGE>


         In   consideration  of  the  services   provided  by  Recipients,   the
Distributor shall make the following payments to Recipients:

                  (i) Service Fee. In  consideration of  administrative  support
services  provided by a Recipient  during a calendar  quarter,  the  Distributor
shall make service fee payments to that Recipient  quarterly,  within forty-five
(45) days of the end of each calendar  quarter,  at a rate not to exceed 0.0625%
(0.25% on an annual  basis) of the average  during the  calendar  quarter of the
aggregate  net asset value of Shares,  computed as of the close of each business
day,  constituting  Qualified  Holdings owned  beneficially  or of record by the
Recipient or by its Customers for a period of more than the minimum  period (the
"Minimum  Holding  Period"),  if any,  that  may be set  from  time to time by a
majority of the Independent Trustees.

         Alternatively,  the  Distributor  may,  at its  sole  option,  make the
following  service fee payments to any Recipient  quarterly,  within  forty-five
(45)  days  of the  end of each  calendar  quarter:  (A)  "Advance  Service  Fee
Payments"  at a rate not to exceed  0.25% of the  average  during  the  calendar
quarter of the aggregate net asset value of Shares,  computed as of the close of
business on the day such Shares are sold,  constituting Qualified Holdings, sold
by the Recipient during that quarter and owned  beneficially or of record by the
Recipient  or by its  Customers,  plus (B) service fee payments at a rate not to
exceed  0.0625%  (0.25% on an annual  basis) of the average  during the calendar
quarter of the aggregate net asset value of Shares,  computed as of the close of
each business day,  constituting  Qualified  Holdings owned  beneficially  or of
record by the  Recipient or by its  Customers  for a period of more than one (1)
year. At the Distributor's sole option, Advance Service Fee Payments may be made
more often than quarterly,  and sooner than the end of the calendar quarter.  In
the event Shares are redeemed less than one year after the date such Shares were
sold,  the Recipient is obligated to and will repay the  Distributor on demand a
pro rata portion of such Advance Service Fee Payments, based on the ratio of the
time such Shares were held to one (1) year.

          The  administrative  support  services to be rendered by Recipients in
connection  with the  Accounts  may  include,  but shall not be limited  to, the
following:  answering  routine inquiries  concerning the Fund,  assisting in the
establishment  and  maintenance  of  accounts  or  sub-accounts  in the Fund and
processing Share redemption transactions, making the Fund's investment plans and
dividend  payment options  available,  and providing such other  information and
services  in  connection  with the  rendering  of personal  services  and/or the
maintenance of Accounts, as the Distributor or the Fund may reasonably request.

                  (ii)  Distribution  Assistance Fee (Asset-Based  Sales Charge)
Payments.  Irrespective  of whichever  alternative  method of making service fee
payments  to  Recipients  is  selected  by  the  Distributor,  in  addition  the
Distributor  shall make  distribution  assistance fee payments to each Recipient
quarterly,  within  forty-five (45) days after the end of each calendar quarter,
at a rate not to exceed 0.1875% (0.75% on an annual basis) of the average during
the calendar  quarter of the aggregate net asset value of Shares  computed as of
the  close  of  each  business  day   constituting   Qualified   Holdings  owned
beneficially or of record by the Recipient or its Customers for a period of more
than one (1) year.  Alternatively,  at its sole option, the Distributor may make
distribution  assistance  fee  payments  to a Recipient  quarterly,  at the rate
described above, on Shares constituting Qualified Holdings owned beneficially or
of record by the Recipient or its Customers without regard to the 1-year holding
period described above.  Distribution assistance fee payments shall be made only
to Recipients that are registered with the SEC as a broker-dealer  or are exempt
from registration.

         The  distribution  assistance  to be  rendered  by  the  Recipients  in
connection with the sale of Shares may include, but shall not be limited to, the
following:  distributing  sales  literature  and  prospectuses  other than those
furnished to current Shareholders, providing compensation to and paying expenses
of  personnel of the  Recipient  who support the  distribution  of Shares by the
Recipient,  and providing such other information and services in connection with
the  distribution  of  Shares  as the  Distributor  or the Fund  may  reasonably
request.



<PAGE>


         (c) A majority of the Independent Trustees may at any time or from time
to time (i) increase or decrease the rate of fees to be paid to the  Distributor
or to any  Recipient,  but not to exceed the rates set forth above,  and/or (ii)
direct the Distributor to increase or decrease any Minimum  Holding Period,  any
maximum period set by a majority of the  Independent  Trustees during which fees
will be paid on Shares constituting  Qualified Holdings owned beneficially or of
record by a Recipient or by its Customers  (the "Maximum  Holding  Period"),  or
Minimum Qualified  Holdings.  The Distributor shall notify all Recipients of any
Minimum  Qualified  Holdings,  Maximum Holding Period and Minimum Holding Period
that  are  established  and  the  rate  of  payments  hereunder   applicable  to
Recipients,  and shall provide each  Recipient with written notice within thirty
(30) days after any change in these provisions.  Inclusion of such provisions or
a change in such  provisions  in a supplement or amendment to or revision of the
prospectus of the Fund shall constitute sufficient notice.

         (d) The  Service  Fee and the  Asset-Based  Sales  Charge on Shares are
subject to reduction or  elimination  under the limits to which the  Distributor
is, or may become, subject under the NASD Conduct Rules.

         (e) Under the Plan,  payments  may also be made to  Recipients:  (i) by
OppenheimerFunds, Inc. ("OFI") from its own resources (which may include profits
derived  from  the  advisory  fee it  receives  from the  Fund),  or (ii) by the
Distributor  (a subsidiary of OFI),  from its own  resources,  from  Asset-Based
Sales Charge payments or from the proceeds of its borrowings, in either case, in
the discretion of OFI or the Distributor, respectively.

         (f)  Recipients  are  intended to have  certain  rights as  third-party
beneficiaries  under this Plan,  subject to the  limitations set forth below. It
may be  presumed  that a  Recipient  has  provided  distribution  assistance  or
administrative  support services qualifying for payment under the Plan if it has
Qualified  Holdings of Shares that  entitle it to  payments  under the Plan.  If
either the Distributor or the Board believe that,  notwithstanding  the level of
Qualified Holdings,  a Recipient may not be rendering  appropriate  distribution
assistance  in  connection  with the sale of  Shares or  administrative  support
services for Accounts, then the Distributor,  at the request of the Board, shall
require the Recipient to provide a written report or other information to verify
that said  Recipient is providing  appropriate  distribution  assistance  and/or
services in this regard.  If the  Distributor  or the Board of Trustees still is
not  satisfied  after the receipt of such  report,  either may take  appropriate
steps to  terminate  the  Recipient's  status  as a  Recipient  under  the Plan,
whereupon such Recipient's rights as a third-party  beneficiary  hereunder shall
terminate.   Additionally,   in  their  discretion  a  majority  of  the  Fund's
Independent  Trustees at any time may remove any broker,  dealer,  bank or other
person or entity as a Recipient, whereupon such person's or entity's rights as a
third-party  beneficiary  hereof  shall  terminate.  Notwithstanding  any  other
provision of this Plan,  this Plan does not obligate or in any way make the Fund
liable  to make any  payment  whatsoever  to any  person or  entity  other  than
directly  to the  Distributor.  The  Distributor  has no  obligation  to pay any
Service Fees or Distribution Assistance Fees to any Recipient if the Distributor
has not received  payment of Service Fees or  Distribution  Assistance Fees from
the Fund.

4.  Selection  and  Nomination  of Trustees.  While this Plan is in effect,  the
selection  and  nomination  of  persons to be  Trustees  of the Fund who are not
"interested persons" of the Fund  ("Disinterested  Trustees") shall be committed
to the discretion of the incumbent Disinterested Trustees.  Nothing herein shall
prevent the incumbent  Disinterested  Trustees from  soliciting the views or the
involvement  of  others in such  selection  or  nomination  as long as the final
decision on any such  selection and  nomination is approved by a majority of the
incumbent Disinterested Trustees.

5.  Reports.  While  this Plan is in  effect,  the  Treasurer  of the Fund shall
provide written reports to the Fund's Board for its review, detailing the amount
of all payments made under this Plan and the purpose for which the payments were
made.  The reports  shall be  provided  quarterly,  and shall state  whether all
provisions of Section 3 of this Plan have been complied with.

6. Related  Agreements.  Any agreement  related to this Plan shall be in writing
and shall  provide  that:  (i) such  agreement  may be  terminated  at any time,
without  payment  of any  penalty,  by a vote of a majority  of the  Independent
Trustees  or by a vote of the  holders of a  "majority"  (as defined in the 1940
Act) of the Fund's  outstanding  voting  Class C shares;  (ii) such  termination
shall be on not more than sixty days'  written  notice to any other party to the
agreement;  (iii) such agreement shall  automatically  terminate in the event of
its "assignment" (as defined in the 1940 Act); (iv) such agreement shall go into
effect when approved by a vote of the Board and its Independent Trustees cast in
person at a meeting called for the purpose of voting on such agreement;  and (v)
such agreement shall,  unless terminated as herein provided,  continue in effect
from year to year only so long as such  continuance is specifically  approved at
least  annually  by a vote of the Board  and its  Independent  Trustees  cast in
person at a meeting called for the purpose of voting on such continuance.

7.  Effectiveness,  Continuation,  Termination  and Amendment.  This Amended and
Restated  Plan has been  approved by a vote of the Board and of the  Independent
Trustees and replaces the Fund's prior Distribution and Service Plan for Class C
Shares.  Unless terminated as hereinafter  provided, it shall continue in effect
until renewed by the Board in accordance  with the Rule and thereafter from year
to  year  or as the  Board  may  otherwise  determine  but  only so long as such
continuance  is  specifically  approved at least annually by a vote of the Board
and its Independent  Trustees cast in person at a meeting called for the purpose
of voting on such continuance.

         This Plan may not be  amended  to  increase  materially  the  amount of
payments  to  be  made  under  this  Plan,  without  approval  of  the  Class  C
Shareholders  at a meeting  called for that purpose and all material  amendments
must be approved by a vote of the Board and of the Independent Trustees.

         This Plan may be  terminated at any time by a vote of a majority of the
Independent  Trustees or by the vote of the holders of a "majority"  (as defined
in the 1940 Act) of the Fund's  outstanding  Class C voting shares. In the event
of such  termination,  the Board and its  Independent  Trustees shall  determine
whether the  Distributor  shall be entitled to payment from the Fund of all or a
portion of the Service  Fee and/or the  Asset-Based  Sales  Charge in respect of
Shares sold prior to the effective date of such termination.

8. Disclaimer of Shareholder and Trustee Liability.  The Distributor understands
that the  obligations  of the Fund  under  this  Plan are not  binding  upon any
Trustee or  shareholder of the Fund  personally,  but bind only the Fund and the
Fund's property. The Distributor represents that it has notice of the provisions
of the  Declaration  of Trust of the Fund  disclaiming  shareholder  and Trustee
liability for acts or obligations of the Fund.
