Expenses

   
The Fund pays a variety of  expenses  directly  for  management  of its  assets,
administration,  distribution  of its  shares  and  other  services,  and  those
expenses are subtracted from the Fund's assets to calculate the Fund's net asset
value per share.  All  shareholders  therefore  pay those  expenses  indirectly.
Shareholders  pay other  expenses  directly,  such as sales  charges and account
transaction  charges.  The following  tables are provided to help you understand
your  direct  expenses  of  investing  in the Fund and your  share of the Fund's
business  operating  expenses  that you  might  expect to bear  indirectly.  The
numbers  below are based on the Fund's  expenses  during  its fiscal  year ended
August 31, 1997.

      o  Shareholder  Transaction  Expenses  are charges you pay when you buy or
sell  shares of the  Fund.  Please  refer to "About  Your  Account"  from  pages
26through 49 for an explanation of how and when these charges apply.

(1)If  you  invest  $1  million  or  more($500,000  or  more  for  purchases  by
"Retirement  Plans," as defined in "Class A Contingent Deferred Sales Charge" on
page 31), in Class A shares,  you may have to pay a sales  charge of up to 1% if
you sell your shares within 12 calendar  months (18 months for shares  purchased
prior to May 1,  1997)  from the end of the  calendar  month  during  which  you
purchased those shares.  See "How to Buy Shares - Buying Class A Shares," below.
(2)See  "How to Buy  Shares - Buying  Class B Shares"  and "How to Buy  Shares -
Buying Class C Shares," below, for more  information on the contingent  deferred
sales charges.

(3)There is a $10 transaction fee for redemptions paid by Federal
Funds wire but not for redemptions paid by check or ACH transfer
through AccountLink.  See "How to Sell Shares," below.

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

</TABLE>

   
    The  numbers  in the chart  above are based on the  Fund's  expenses  in its
fiscal year ended August 31, 1997.  These  amounts are shown as a percentage  of
the  average  net assets of each class of the Fund's  shares for that year.  The
"12b-1  Distribution  Plan Fees" for Class A shares are the  service  fees.  The
maximum is 0.25% of average net assets for that  Class.  For Class B and Class C
shares,  the  Distribution  Plan Fees are the service plan fees (the maximum fee
for each class is 0.25% of average  annual net assets of the  respective  class)
and the  asset-based  sales charge of 0.75% of average  annual net assets of the
respective  class.  These plans are  described in greater  detail in "How to Buy
Shares."  Class Y shares  were  first  publicly  offered  on  November  1, 1996.
Therefore, the Other Expenses for Class Y shares are estimates based on expenses
that would have been payable if Class Y shares had been  outstanding  during the
full fiscal period. The actual expenses for each class of shares in future years
may be more or less than the  numbers  in the  chart,  depending  on a number of
factors,  including changes in the actual value of the Fund's assets represented
by each class of shares.
    

      o Examples.  To try to show the effect of these expenses on
an investment over time, we have created the hypothetical examples

                                     -4-

<PAGE>



shown below.  Assume that you make $1,000 investments in each class of shares of
the  Fund,  and that the  Fund's  annual  return is 5%,  and that its  operating
expenses for each class are the ones shown in the Annual Fund Operating Expenses
chart  above.  If you were to redeem your shares at the end of each period shown
below, your investment would incur the following  expenses by the end of 1, 3, 5
and 10 years:

   
                       1 year      3 years      5 years       10 years*
- -------------------------------------------------------------
Class A Shares         $67         $86          $107          $166
Class B Shares         $67         $83          $112          $162
Class C Shares         $27         $53          $92           $200
Class Y Shares         $7          $21          $36           $81
    

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

   
                       1 year      3 years      5 years       10 years*
- -------------------------------------------------------------
Class A Shares         $67         $86          $107          $166
Class B Shares         $17         $53          $92           $162
Class C Shares         $17         $53          $92           $200
Class Y Shares         $7          $21          $36           $81

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

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

      o What does the Fund  Invest in? The Fund  emphasizes  investments  in (1)
equity  securities,  such as common  stocks,  preferred  stocks and  convertible
securities, and (2) debt securities,  such as bonds and debentures. The Fund may
also  assume  a  temporary  defensive  position  when  appropriate  to  do so by
investing in cash  equivalents.  The Fund may also write  covered  calls and use
derivative  investments  and  certain  hedging  instruments  to  try  to  manage
investment  risks.  These  investments  and  investment  methods  are more fully
explained in "Investment Objective and Policies," starting on page 12.

   
      o Who Manages the Fund? The Fund's  investment  adviser (the "Manager") is
OppenheimerFunds,  Inc. The Manager (including  subsidiaries) manages investment
company  portfolios  having over $75  billion in assets.  The Manager is paid an
advisory fee by the Fund, based on its net assets.  The Fund's portfolio manager
is Mr.  Robert J.  Milnamow,  who is employed by the  Manager.  He is  primarily
responsible  for the  selection  of the Fund's  securities.  The Fund's Board of
Directors,  elected by  shareholders,  oversees the  investment  adviser and the
portfolio manager. Please refer to "How the Fund is Managed" starting on page 20
for more information about the Manager and its fees.
    

      o How Risky is the Fund? All investments  carry risks to some degree.  The
Fund's  investments  in stocks and bonds are  subject to changes in their  value
from a number of  factors  such as  changes  in  general  bond and stock  market
movements,  or the change in value of  particular  stocks or bonds because of an
event affecting the issuer.  Changes in interest rates can also affect stock and
bond prices.  These changes affect the value of the Fund's  investments  and its
price per share. The Fund's investments in foreign securities involve additional
risks not associated with  investments in domestic  securities,  including risks
associated with changes in currency rates.

      In the Oppenheimer funds spectrum, the Fund is generally more conservative
than aggressive  growth funds,  but more  aggressive than investment  grade bond
funds. While the Manager tries to reduce risks by diversifying  investments,  by
carefully  researching  securities  before  they are  purchased  for the  Fund's
portfolio, and

                                     -6-

in some cases by using hedging  techniques,  there is no guarantee of success in
achieving the Fund's  investment  objective and your shares may be worth more or
less than their original cost when you redeem them.  Please refer to "Investment
Risks"  starting  on  page  13  for a more  complete  discussion  of the  Fund's
investment risks.

      o How Can I Buy  Shares?  You can buy shares  Class A, Class B and Class C
shares through your dealer or financial institution,  or you can purchase shares
directly  through the  Distributor  by completing an  Application or by using an
Automatic Investment Plan under AccountLink. Please refer to "How to Buy Shares"
on page 26 for more details.

   
      o Will I Pay a Sales Charge to Buy Shares?  The Fund offers the individual
investor three classes of shares. All classes have the same investment portfolio
but  different  expenses.  Class A shares are  offered  with a  front-end  sales
charge, starting at 5.75%, and reduced for larger purchases.  Class B shares are
offered  without a front-end  sales  charge,  but may be subject to a contingent
deferred  sales charge  (starting at 5% and declining as shares are held longer)
if redeemed  within 6 years of  purchase.  Class C shares are offered  without a
front-end sales charge, but may be subject to a contingent deferred sales charge
of 1% if  redeemed  within  12  months  of  purchase.  There  is also an  annual
asset-based  sales charge on Class B and Class C shares.  Please  review "How to
Buy Shares"  starting on page 26 for more details,  including a discussion about
factors you and your  financial  advisor should  consider in  determining  which
class may be appropriate for you.
    

      o How Can I Sell My Shares? Shares can be redeemed by mail or by telephone
call to the Transfer  Agent on any business day, or through your dealer.  Please
refer  to "How to Sell  Shares"  on page  42.  The  Fund  also  offers  exchange
privileges to other Oppenheimer funds,  described in "How to Exchange Shares" on
page 44.

   
      o How Has the Fund Performed? The Fund measures its performance by quoting
its total returns,  average  annual total returns and cumulative  total returns,
which  measure  historical  performance.  Those  returns  can be compared to the
returns (over similar  periods) of other funds. Of course,  other funds may have
different  objectives,  investments,  and levels of risk. The Fund's performance
can also be compared to a broad-based  market index, which we have done on pages
24 and 25. Please  remember  that past  performance  does not  guarantee  future
results.

portfolio  securities  for the  period,  divided by the total  number of related
shares purchased and sold. Generally,  non-U.S.  commissions are lower than U.S.
commissions  when  expressed  as cents per share but higher when  expressed as a
percentage  of  transactions  because  of the  lower  per-share  prices  of many
non-U.S. securities.

Investment Objective and Policies

   
Objective.  The Fund's investment  objective is to seek high total return (which
includes  current  income and capital  appreciation  in the value of its shares)
from equity and debt securities.
    

Investment  Policies and  Strategies.  The Fund  emphasizes  investments  in (1)
equity  securities,  such as common  stocks,  preferred  stocks and  convertible
securities, and (2) debt securities,  such as bonds and debentures. The Fund may
also  assume  a  temporary  defensive  position  when  appropriate  to  do so by
investing in cash equivalents, as discussed below. The composition of the Fund's
portfolio among the different  types of permitted  investments and maturities of
debt  instruments  will vary  from time to time  based  upon the  evaluation  of
economic and market trends by the Fund's investment  adviser,  OppenheimerFunds,
Inc. (the "Manager"),  and perceived relative total anticipated return from such
types of securities.

   
      The Fund may try to hedge against  losses in the value of its portfolio of
securities by using hedging  strategies  and  derivative  investments  described
below. The Fund's portfolio manager may employ special investment  techniques in
selecting  securities for the Fund, which are also described  below.  Additional
information  may be found about these  strategies and techniques  under the same
headings in the Statement of Additional Information.
    

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

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

   
      o Portfolio Turnover.  "Portfolio turnover" describes the rate
at which the fund traded its portfolio securities during its last
fiscal year.  For example, if a fund sold all of its securities
    

                                     -9-

<PAGE>



   
during the year,  its portfolio  turnover  rate would have been 100%.  Portfolio
turnover affects  brokerage costs the Fund pays. The Fund may engage  frequently
in short-term trading to try to achieve its objective.  The Financial Highlights
table above shows the Fund's portfolio turnover rates during prior fiscal years.
    

Investment Risks.

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

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

      o Stock Investment Risks.  Because the Fund invests a substantial  portion
of its assets in stocks,  the value of the Fund's  portfolio will be affected by
changes in the stock  markets.  At times,  the stock markets can be volatile and
stock prices can change  substantially.  This market risk will affect the Fund's
net asset  value per  share,  which will  fluctuate  as the values of the Fund's
portfolio  securities  change.  Not all stock prices change  uniformly or at the
same time and not all stock markets move in the same direction at the same time.
Other  factors can affect a particular  stock's  prices,  such as poor  earnings
reports by an  issuer,  loss of major  customers,  major  litigation  against an
issuer, or changes in government regulations affecting an industry.
Not all of these factors can be predicted.

      The Fund attempts to limit market risks by diversifying  its  investments,
that is, by not holding a substantial  amount of stock of any one company and by
not  investing  too great a percentage  of the Fund's assets in any one company.
Also, the Fund does not

                                     -10-

<PAGE>



concentrate its investments in any one industry or group of
industries.

      o Interest Rate Risks. In addition to credit risks,  described below, debt
securities  are subject to changes in their  value due to changes in  prevailing
interest rates. When prevailing interest rates fall, the value of already-issued
debt  securities  generally  rise.  When  interest  rates  rise,  the  values of
already-issued  debt  securities  generally  decline.  The  magnitude  of  these
fluctuations  will  often  be  greater  for  longer-term  debt  securities  than
shorter-term  debt  securities.  Changes in the value of securities  held by the
Fund mean that the Fund's  share  prices can go up or down when  interest  rates
change because of the effect of the change on the value of the Fund's  portfolio
of debt securities.

      o Foreign  Securities  Have Special Risks.  The Fund may invest in foreign
securities.  While foreign  securities offer special  investment  opportunities,
there are also special risks.  The change in value of a foreign currency against
the U.S.  dollar will result in a change in the U.S.  dollar value of securities
denominated  in that foreign  currency.  Foreign  issuers are not subject to the
same accounting and disclosure  requirements that U.S. companies are subject to.
The  value  of  foreign   investments  may  be  affected  by  exchange   control
regulations,  expropriation or  nationalization  of a company's assets,  foreign
taxes, delays in settlement of transactions, changes in governmental economic or
monetary policy in the U.S. or abroad,  or other political and economic factors.
Securities in emerging market  countries may be more difficult to sell and their
prices may be more  volatile.  More  information  about the risks and  potential
rewards of investing  in foreign  securities  is  contained in the  Statement of
Additional Information.

   
      o  Special  Risks  of  Lower-Grade  Securities.  The  Manager  may  select
high-yield,  below  investment  grade debt securities  (including both rated and
unrated securities).  These "lower-grade" securities are commonly known as "junk
bonds." All corporate debt securities  (whether foreign or domestic) are subject
to some degree of credit risk.  Credit risk relates to the ability of the issuer
to meet  interest  or  principal  payments  on a security  as they  become  due.
Generally,  higher yielding lower-grade bonds,  whether rated or unrated,  often
have  speculative  characteristics  and  special  risks  that make them  riskier
investments  than investment  grade securities and are subject to greater credit
risks.  They may be subject to greater market  fluctuations  and risk of loss of
income and principal than lower yielding investment grade securities.  There may
be  less  of a  market  for  them  and  therefore  may be  harder  to sell at an
acceptable price.  There is a relatively  greater  possibility that the issuer's
earnings may be  insufficient to make the payments of interest and principal due
on the bonds. The issuer's low  creditworthiness  may increase the potential for
its
    

                                     -11-

<PAGE>



insolvency.  A decline  in their  values is also  likely in the high  yield bond
market during a general economic  downturn.  An economic downturn or an increase
in  interest  rates could  severely  disrupt the market for high yield bonds and
adversely  affect the value of outstanding  bonds and the ability of the issuers
to repay principal and interest. For foreign lower-grade debt securities,  these
risks are in addition to the risks of investing in foreign securities, described
above.  These risks mean that the Fund may not achieve the expected  income from
lower-grade  securities,  and that the Fund's  net asset  value per share may be
affected  by  declines  in  value  of  these  securities.  However,  the  Fund's
limitations  on  investments in these types of securities may reduce some of the
risk,  as  will  the  Fund's  policy  of  diversifying  its  investments.  Also,
convertible  securities  may be less  subject to some of these  risks than other
debt  securities,  to the extent they can be converted into stock,  which may be
more liquid and less affected by these other risk factors.

      o Hedging instruments can be volatile  instruments and may involve special
risks.  The  Fund  may  invest  in  a  number  of  different  kinds  of  hedging
instruments.  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 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,  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 and will not be able to realize  any profit if the
investment has increased in value above the call price.  In writing a put, there
is a risk that the Fund may be  required  to buy the  underlying  security  at a
disadvantageous  price.  The use of Forward  Contracts  may reduce the gain that
would otherwise result from a change in the relationship between the U.S. dollar
and a foreign currency.  These risks and the hedging strategies the Fund may use
are described in greater detail in the Statement of Additional Information.



      o There are special risks in investing in derivative
investments.  The Fund can invest in a number of different kinds of
"derivative" investments.  In general, a "derivative investment" is
    

                                     -12-

<PAGE>



   
a specially  designed  investment whose performance is linked to the performance
of another investment or security, such as an option, future, index, currency or
commodity.  The company issuing the instrument may fail to pay the amount due on
the maturity of the instrument.  Also, the underlying  investment or security on
which the derivative is based,  and the derivative  itself,  may not perform the
way the  Manager  expects it to  perform.  Markets,  underlying  securities  and
indices may move in a direction not  anticipated by the Manager.  Performance of
derivative  investments may also be influenced by interest rate and stock market
changes in the U.S. and abroad.  All of this can mean that the Fund will realize
less principal or income from the investment than expected.  Certain  derivative
investments  held by the Fund may be illiquid.  Please  refer to  "Illiquid  and
Restricted Securities," below, for more information.
    

Investment Techniques and Strategies.

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

      o Foreign  Securities.  The Fund may purchase  equity and debt  securities
issued or  guaranteed  by  foreign  companies  or foreign  governments  or their
agencies. The Fund may buy securities of companies in any country,  developed or
underdeveloped. There is no limit on the amount of the Fund's assets that may be
invested in foreign  securities.  Foreign currency will be held by the Fund only
in connection with the purchase or sale of foreign securities.

   
      o Warrants and Rights. Warrants are basically options to purchase stock at
set prices  that are valid for a limited  period of time.  Rights are similar to
warrants but normally have a short duration and are distributed  directly by the
issuer to its shareholders. The Fund may invest up to 10% of its total assets in
warrants or rights,  although the Fund does not currently  intend to invest more
than 5% of its total  assets in warrants or rights.  For further  details  about
these  investments,  please refer to "Warrants  and Rights" in the  Statement of
Additional Information.
    

      o  Investing  in  Small,  Unseasoned  Companies.  The Fund may  invest  in
securities of small, unseasoned companies. These are companies that have been in
operation  for  less  than  three  years,   including  the   operations  of  any
predecessors.  Securities of these companies may have limited  liquidity and may
be subject to volatility in their prices.  The Fund currently  intends to invest
no more than 5% of its net assets in securities of small, unseasoned issuers.


                                     -13-

<PAGE>



   
      o Investments  in Bonds and  Convertible  Securities.  The Fund invests in
bonds,  debentures and other debt  securities to seek its investment  objective.
The Fund's investments may include investment-grade bonds, which are bonds rated
at least "Baa" by Moody's Investors Service, Inc. ("Moody's"), at least "BBB" by
Standard  & Poor's  Corporation  ("Standard  & Poor's")  or Duff & Phelps,  Inc.
("Duff & Phelps"),  or have comparable ratings by another nationally  recognized
statistical  rating  organization.  If the securities are unrated,  they must be
judged by the Manager to be of  comparable  quality to bonds rated as investment
grade.

      The Fund may invest up to 25% of its total  assets in "lower  grade"  debt
securities  commonly known as "junk bonds," although the Fund does not currently
intend  to  invest  more  that  15% of its  total  assets  in lower  grade  debt
securities.  "Lower-grade"  debt  securities  are those rated below  "investment
grade"  which means they have a rating lower than "Baa" by Moody's or lower than
"BBB" by Standard & Poor's or Duff & Phelps,  or similar ratings by other rating
organizations,  or if unrated, are determined by the Manager to be of comparable
quality to debt securities rated below investment  grade. The Fund may invest in
securities rated as low as "C" or "D" or which may be in default at the time the
Fund buys them.  While  securities rated "Baa" by Moody's or "BBB" by Standard &
Poor's  or Duff & Phelps  are  investment  grade and are not  regarded  as "junk
bonds,"  those  securities  may be  subject  to special  risks as  described  in
"Investment Risks," above.
    

      The Fund may  invest no more than 10% of its total  assets in  lower-grade
debt  securities  that  are not  convertible.  The  Fund  considers  convertible
securities to be "equity  equivalents" because of the conversion feature and the
security's rating has less impact on the investment decision than in the case of
non-convertible securities.

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

      o Borrowing  for  Leverage.  From time to time,  the Fund may increase its
ownership  of  securities  by  borrowing  from banks on an  unsecured  basis and
investing  the  borrowed  funds  (on which it will pay  interest).  The Fund may
borrow only if it maintains a 300% ratio of assets to borrowings at all times in
the manner set forth in the Investment  Company Act.  Interest on borrowed money
is an  expense  the  Fund  would  not  otherwise  incur,  so  that  it may  have
substantially  reduced  net  investment  income  during  periods of  substantial
borrowings.  The Fund's  ability to borrow money from banks  subject to the 300%
asset coverage requirement is a
    

                                     -14-

<PAGE>



fundamental policy.


   
      o Temporary Defensive Investments. In times of unstable market or economic
conditions,  when  fluctuations in the value of the Fund's net assets may occur,
the  Manager  may  determine  it  appropriate  to assume a  temporary  defensive
position and invest an unlimited amount of assets in: (i) obligations  issued or
guaranteed  by the U.S.  Government,  its agencies or  instrumentalities  ("U.S.
Government Securities");  (ii) commercial paper rated in the highest category by
an established  rating  organization;  (iii) certificates of deposit or bankers'
acceptances of domestic banks with assets of $1 billion or more; (iv) any of the
foregoing maturing in one year or less (generally known as "cash  equivalents");
(v)  short-term  debt  obligations;  or (vi)  repurchase  agreements  (explained
below).
    

      o "When-Issued" and Delayed Delivery  Transactions.  The Fund may purchase
securities  on a  "when-issued"  basis and may purchase or sell  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.  There may be a risk of loss to the Fund if the value of the  security
declines prior to the settlement date.


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

   
      o Illiquid and  Restricted  Securities.  Under the policies and procedures
established  by the Board of Directors of Oppenheimer  Main Street Funds,  Inc.,
the  Manager  determines  the  liquidity  of certain of the Fund's  investments.
Investments may be illiquid  because of the absence of an active trading market,
making it difficult to value them or dispose of them  promptly at an  acceptable
price.  A restricted  security is one that has a contractual  restriction on its
resale  or which  cannot  be sold  publicly  until it is  registered  under  the
Securities Act of 1933. The Fund will not invest more than 10% of its net assets
in illiquid or restricted securities (the Board may increase that
    

                                     -15-

<PAGE>



   
limit to 15%).  Certain  restricted  securities  that are eligible for resale to
qualified  institutional  purchasers,  are not subject to that  limit.  Illiquid
securities  include repurchase  agreements  maturing in more than seven days, or
certain  participation  interests other than those with puts exercisable  within
seven days. The Manager monitors  holdings of illiquid  securities on an ongoing
basis to determine whether to sell any holdings to maintain adequate liquidity.

      o Loans of Portfolio Securities. In an attempt to raise income or to raise
cash for  liquidity  purposes,  the Fund may lend its  portfolio  securities  to
certain types of eligible  borrowers  approved by the Board of  Directors.  Each
loan  must  be   collateralized   in  accordance  with   applicable   regulatory
requirements. After any loan, the value of the securities loaned must not exceed
25% of the value of the Fund's total assets.  There are some 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
in the coming year.

      o Derivative  Investments.  In general,  a  "derivative  investment"  is a
specially-designed  investment.  Its performance is linked to the performance of
another investment or security, such as an option, future, index or currency. In
the  broadest  sense,  exchange-traded  options,  futures  contracts,  and other
hedging   instruments   the  Fund  might  use  may  be  considered   "derivative
investments." The Fund may use other derivative  investments  because they offer
the potential for increased income and principal value.

      One  example  of  derivative  investments  the  Fund may  invest  in is an
"index-linked"  note, on which principal and/or interest  payments depend on the
performance  of an underlying  index.  Currency-indexed  securities  are another
example.  These are typically short-term or  intermediate-term  debt securities.
Their value at maturity or the rates at which they pay income are  determined by
the change in value of the U.S. dollar against one or more foreign currencies or
an index. In some cases, these securities may pay an amount at maturity based on
a multiple of the amount of the  relative  currency  movements.  This variety of
index security offers the potential for greater income or principal payments but
at a greater risk of loss.

      Other  derivative   investments  the  Fund  may  invest  in  include  debt
exchangeable for common stock of an issuer or,  "equity-linked  debt securities"
of an issuer.  At maturity,  the debt  security is exchanged for common stock of
the issuer or is payable in an amount based on the price of the issuer's  common
stock at the time of maturity. Both cases present a risk that the amount payable
at
    

                                     -16-

<PAGE>



maturity will be less than the  principal  amount of the debt (because the price
of the issuer's common stock may not be as high as was expected).

   
      o Hedging.  The Fund may buy and sell certain kinds of futures  contracts,
put and call options, forward contracts and options on futures and broadly-based
securities indices. 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,  described  below.  The  hedging  instruments  the Fund may use are
described  below  and in  greater  detail in "Other  Investment  Techniques  and
Strategies" in the Statement of Additional Information.


      The Fund may buy and sell  options,  futures and forward  contracts  for a
number  of  purposes.  It  may  do so to  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 also use  certain  kinds of  hedging
instruments in an effort to manage its exposure to changing interest rates.
    

      Some of these strategies, such as selling futures, buying puts and writing
covered calls,  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.  Forward contracts are used to try
to manage  foreign  currency risks on the Fund's  foreign  investments.  Foreign
currency options are used to try to protect against declines in the dollar value
of foreign  securities  the Fund owns, or to protect  against an increase in the
dollar cost of buying foreign securities.  Writing covered call options may also
provide income to the Fund for liquidity purposes or to raise cash to distribute
to shareholders.

   
      o Futures.  The Fund may buy and sell futures contracts that relate to (1)
interest  rates  (these  are  referred  to  as  Interest  Rate   Futures),   (2)
broadly-based  securities indices (these are referred to as Financial  Futures),
(3) foreign  currencies  (these are  referred to as Forward  Contracts),  or (4)
commodities (these are referred to as commodity futures).

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


                                     -17-

<PAGE>



   
      If the Fund sells (that is,  writes) a call option,  it must be "covered."
That means the Fund must own the security  subject to the call while the call is
outstanding,  or, for other  types of  written  calls,  the Fund must  segregate
liquid assets to enable it to satisfy its  obligations if the call is exercised.
Up to 25% of the Fund's total assets may be subject to calls.

      The Fund may buy puts whether or not it holds the underlying investment in
the  portfolio.  If the Fund writes a put, the put must be covered by segregated
liquid  assets.  The Fund will not write puts if more than 25% of the Fund's net
assets would have to be segregated to cover put options.
    

      o Forward  Contracts.  Forward  contracts  are foreign  currency  exchange
contracts.  They are used to buy or sell foreign currency for future delivery at
a fixed  price.  The Fund  uses  them to "lock  in" the U.S.  dollar  price of a
security  denominated in a foreign currency that the Fund has bought or sold, or
to protect  against  possible  losses from changes in the relative values of the
U.S.  dollar and a foreign  currency.  The Fund  limits its  exposure in foreign
currency  exchange  contracts in a particular  foreign currency to the amount of
its assets denominated in that currency or a  closely-correlated  currency.  The
Fund may also use  "cross-hedging"  where the Fund  hedges  against  changes  in
currencies other than the currency in which a security it holds is denominated.

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

      o The Fund cannot buy  securities  issued or  guaranteed by any one issuer
(except the U.S. Government or any of its agencies or instrumentalities) if with
respect to 75% of its total  assets,  more than 5% of its total  assets would be
invested in  securities  of that  issuer,  or it would then own more than 10% of
that issuer's voting securities;

      o The Fund cannot lend money except in connection  with the acquisition of
debt securities which the Fund's investment  policies and restrictions permit it
to purchase,  the Fund may also make loans of portfolio  securities,  subject to
the restrictions stated under "Loans of Portfolio Securities"; or

      o The Fund cannot concentrate investments to the extent of 25%
or more of its total assets in any industry, however, there is no
limitation as to investment in U.S. Government Securities.

   
      Unless the Prospectus states that a percentage restriction
    

                                     -18-

<PAGE>



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

How the Fund is Managed

Organization  and  History.  The Fund is one of two  investment  portfolios,  or
"series"  of  Oppenheimer  Main  Street  Funds,  Inc.  (the  "Corporation"),  an
open-end,  management  investment company organized as a Maryland corporation in
1987. The Fund is a diversified mutual fund and commenced operations on February
3, 1988.

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

   
      The Board of Directors 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 four classes of shares; Class A, Class B, Class C
and Class Y. All classes invest in the same investment portfolio. Each class has
its own  dividends  and  distributions  and pays certain  expenses  which may be
different for the different  classes.  Each class may have a different net asset
value. Each share has one vote at shareholder  meetings,  with fractional shares
voting  proportionally on matters submitted to the vote of shareholders.  Shares
of each class may have separate  voting rights on matters in which  interests of
one class are different from  interests of another  class,  and only shares of a
particular class vote as a class on matters that affect that class alone. Shares
are freely transferrable.
    

The  Manager  and Its  Affiliates.  The Fund is  managed by the  Manager,  which
chooses 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
Directors,  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

                                     -19-

<PAGE>



conduct its business.

   
      The Manager has operated as an investment  adviser since 1959. The Manager
(including subsidiaries) currently manages investment companies, including other
Oppenheimer  funds,  with  assets of more than $75 billion as of  September  30,
1997, and with more than 3 million shareholder accounts. The Manager is owned by
Oppenheimer Acquisition Corp., a holding company that is owned in part by senior
officers of the Manager and  controlled by  Massachusetts  Mutual Life Insurance
Company.

      o Portfolio Manager.  The portfolio manager and a Vice
President of the Fund is Mr. Robert J. Milnamow, who is also a Vice
President of the Manager.  On November 1, 1995, Mr. Milnamow became
the person principally responsible for the day-to-day management of
the Fund's portfolio.  Previously, Mr. Milnamow was a portfolio
manager with Phoenix Securities Group.

      o Fees and Expenses.  Under the Investment  Advisory  Agreement,  the Fund
pays the Manager the following annual fees,  which decline on additional  assets
as the Fund  grows:  0.65% of the first $200  million of net assets of the Fund,
0.60% of the next  $150  million,  0.55% of the next $150  million  and 0.45% of
average annual net assets in excess of $500 million.  The Fund's  management fee
for its fiscal year ended August 31, 1997 was 0.46% of average annual net assets
for each class of shares.

      The Fund pays expenses related to its daily operations,  such as custodian
fees, certain  Directors' fees,  transfer agency fees, legal 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.  More
information about the Investment  Advisory Agreement and the other expenses paid
by the Fund is contained in the Statement of Additional Information.
    

      There  is  also  information  about  the  Fund's  brokerage  policies  and
practices in  "Brokerage  Policies of the Fund" in the  Statement of  Additional
Information. That section discusses how brokers and dealers are selected for the
Fund's portfolio  transactions.  When deciding which brokers to use, the Manager
is permitted by the Investment  Advisory  Agreement to consider  whether brokers
have sold shares of the Fund or any other funds for which the Manager  serves as
investment adviser.

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

                                     -20-

<PAGE>



sub-distributor for funds managed by a subsidiary of the Manager.

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

Performance of the Fund

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

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

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

   
      When total  returns  are quoted for Class A shares,  normally  the current
maximum initial sales charge has been deducted. When total
    

                                     -21-

<PAGE>



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

How Has the Fund  Performed?  Below is a discussion by the Manager of the Fund's
performance  during its last fiscal year ended  August 31,  1997,  followed by a
graphical  comparison of the Fund's  performance to an  appropriate  broad-based
market index.

      o  Management's  Discussion of  Performance.  During the fiscal year ended
August 31, 1997, the Fund's  performance was positively  affected by a number of
factors including the strong overall  performance of the U.S. stock market.  The
Fund's investments in securities in the financial services sector,  particularly
banks and  insurance  companies  helped  the Fund's  performance.  Additionally,
strong corporate earnings and new products in the  pharmaceutical  industry also
benefited the Funds's  performance.  The Fund's investment in the hotel industry
performed well because of the higher profitability in that sector.  Finally, The
Fund's  investments  were  positively   affected  by  the  deregulation  in  the
telecommunication area.

      During the Fund's last  fiscal  year,  the  performance  of the U.S.  Bond
markets was more volatile.  Early in 1997,  when yields  approached 7%, the Fund
increased its holdings in U.S.  Treasuries  in order to seek current  income for
the Fund. This negatively affected the Fund's capital appreciation,  however, it
helped the Fund seek  current  income and helped to protect the Fund's net asset
value from some of the volatility of the stock market during the last few months
of the fiscal year. The Fund's  portfolio  holdings,  allocations and strategies
are subject to change.

      o Comparing the Fund's  Performance  to the Market.  The graphs below show
the performance of a hypothetical  $10,000 investment in each class of shares of
the Fund held until August 31, 1997. In the case of Class A shares,  performance
is measured from the commencement of operations on February 3, 1988; in the case
of Class B shares,  from the  inception of the class on October 1, 1994;  in the
case of Class C shares, from the inception of the class on December 1, 1993; and
in the case of Class Y shares,  from the  inception  of the class on November 1,
1996.
    

      The Fund's  performance  is  compared  to the  performance  of the S&P 500
Index.  The S&P 500 Index is a  broad-based  index of equity  securities  widely
regarded  as a  general  measurement  of  the  performance  of the  U.S.  equity
securities  market.  The S&P 500 Index performance  reflects the reinvestment of
dividends  but does not  consider  the  effect of capital  gains or  transaction
costs, and

                                     -22-

<PAGE>



none of the data below shows the effect of taxes.  Also, the Fund's  performance
reflects  the  effect of Fund  business  and  operating  expenses.  While  index
comparisons may be useful to provide a benchmark for the Fund's performance,  it
must be noted that the Fund's  investments  are not limited to the securities in
the S&P 500 Index,  which  tend to be  securities  of  larger,  well-capitalized
companies.  Moreover, the index data does not reflect any assessment of the risk
of the investments included in the index.

How to Buy Shares

Classes of Shares. The Fund offers individual  investors three different classes
of shares. Only certain  institutional  investors may purchase a fourth class of
shares, Class Y shares. The different classes of shares represent investments in
the same portfolio of securities but are subject to different  expenses and will
likely have different share prices.

   
      o Class A Shares. If you buy Class A shares,  you may pay an initial sales
charge  on  investments  up to $1  million  (up to  $500,000  for  purchases  by
"Retirement  Plans," as defined in "Class A Contingent Deferred Sales Charge" on
page 31). If you purchase Class A shares as part of an investment of at least $1
million  ($500,000 for  Retirement  Plans) in shares of one or more  Oppenheimer
funds,  you will not pay an initial sales  charge,  but if you sell any of those
shares  within 12 months of buying them (18 months if the shares were  purchased
prior to May 1, 1997),  you may pay a  contingent  deferred  sales  charge.  The
amount  of that  sales  charge  value  will vary  depending  on the  amount  you
invested. Sales charge rates are described in "Buying Class A Shares," below.

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

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

      o Class Y Shares.  Class Y shares are offered only to certain
    


                                     -24-

<PAGE>



   
institutional  investors  that have  special  agreements  with the  Distributor.
Please refer to "Buying Class Y 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  which you should  discuss
with your financial advisor. The Fund's operating costs that apply to a class of
shares and the effect of the different types of sales charges on your investment
will vary your  investment  results  over time.  The most  important  factors to
consider  are how  much you plan to  invest  and how long you plan to hold  your
investment.  If your  goals  and  objectives  change  over  time and you plan to
purchase  additional  shares, you should re-evaluate those factors to see if you
should consider another class of shares.
    

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

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

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

      o Investing for the Short Term.  If you have a short-term
investment horizon (that is, you plan to hold your shares for not

                                     -25-

<PAGE>



more than six years), you should probably consider purchasing Class A or Class C
shares  rather  than  Class B  shares,  because  of the  effect  of the  Class B
contingent  deferred sales charge if you redeem in less than 7 years, as well as
the effect of the Class B asset-based  sales charge on the investment return for
that class in the  short-term.  Class C shares might be the  appropriate  choice
(especially for investments of less than $100,000),  because there is no initial
sales charge on Class C shares,  and the  contingent  deferred sales charge does
not apply to amounts you sell after holding them one year.

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

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

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

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

      o Are There Differences in Account Features That Matter To

                                     -26-

<PAGE>



You?  Because some  account  features may not be available to Class B or Class C
shareholders,  or other features (such as Automatic Withdrawal Plans) may not be
advisable  (because of the effect of the  contingent  deferred sales charge) for
Class B or Class C shareholders, you should carefully review how you plan to use
your  investment  account  before  deciding  which class of shares to buy. Share
certificates  are not available  for Class B and Class C shares,  and if you are
considering  using your shares as collateral for a loan, that may be a factor to
consider.


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


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

      o With Asset Builder Plans,  Automatic Exchange Plans, 403(b)(7) custodial
plans  and  military  allotment  plans,  you can  make  initial  and  subsequent
investments of as little as $25, and subsequent purchases of at least $25 can be
made by telephone through AccountLink.

      o Under  pension  and  profit-sharing  and  401(k)  plans  and  Individual
Retirement  Accounts (IRAs),  you can make an initial investment of as little as
$250 (if your IRA is  established  under an Asset Builder Plan,  the $25 minimum
applies), and subsequent investments may be as little as $25.

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

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

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

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

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

      o  Buying  Shares  Through  OppenheimerFunds   AccountLink.  You  can  use
AccountLink  to link your Fund account  with an account at a U.S.  bank or other
financial  institution that is an Automated Clearing House (ACH) member. You can
then transmit  funds  electronically  to purchase  shares,  to have the Transfer
Agent send redemption  proceeds,  or to transmit  dividends and distributions to
your bank account.

      Shares are  purchased  for your  account on the regular  business  day the
Distributor is instructed by you to initiate the ACH transfer to buy shares. You
can provide  those  instructions  automatically,  under an Asset  Builder  Plan,
described below, or by telephone instructions using OppenheimerFunds  PhoneLink,
also  described  below.  You  should  request  AccountLink   privileges  on  the
application or dealer  settlement  instructions  used to establish your account.
Please refer to "AccountLink," below, for more details.

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

                                     -28-

of Additional Information.

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

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

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

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

   
                          Front-End Sales                  Front-End Sales

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

      o Class A Contingent Deferred Sales Charge. There is no
initial sales charge on purchases of Class A shares of any one or
more of the Oppenheimer funds in the following cases:

      o Purchases by a Retirement  Plan  qualified  under section  401(a) if the
Retirement Plan has total plan assets of $500,000 or more;

      o Purchases aggregating $1 million or more;

   
      o Purchases by a Retirement Plan qualified under sections 401(a) or 401(k)
of the Internal  Revenue Code, by a non-qualified  deferred  compensation  plan,
employee  benefit  plan,  group  Retirement  Plan  (see  "How  to Buy  Shares  -
Retirement  Plans"  in the  Statement  of  Additional  Information  for  further
details),  an employee's 403(b)(7) custodial plan account,  SEP-IRA,  SARSEP, or
SIMPLE plan (all of these  plans are  collectively  referred  to as  "Retirement
Plans"),  that (1) buys shares costing  $500,000 or more or (2) has, at the time
of  purchase,  100 or  more  eligible  participants,  or (3)  certifies  that it
projects to have annual plan purchases of $200,000 or more; or

      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 these 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.

      The Distributor pays dealers of record commissions on those
    

                                     -30-

<PAGE>



   
purchases in an amount equal to (i) 1.0% for non-retirement  plan accounts,  and
(ii) for retirement plan accounts, 1.0% of the first $2.5 million, plus 0.50% of
the next $2.5 million, plus 0.25% of purchases over $5 million,  calculated on a
calendar year basis.  That  commission will be paid only on those purchases that
were not previously  subject to a front-end sales charge and dealer  commission.
No sales commission will be paid to the dealer,  broker or financial institution
on sales of Class A shares purchased with the redemption proceeds of shares of a
mutual  fund  offered  as an  investment  option in a  retirement  plan in which
Oppenheimer  funds  are also  offered  as  investment  options  under a  special
arrangement  with the Distributor if the purchase occurs more than 30 days after
the addition of the Oppenheimer  funds as an investment option to the retirement
plan.

      If you redeem any of those shares  purchased prior to May 1, 1997,  within
18 months  of the end of the  calendar  month of their  purchase,  a  contingent
deferred  sales charge  (called the "Class A contingent  deferred sales charge")
may be deducted  from the  redemption  proceeds.  A Class A contingent  deferred
sales charge may be deducted from the redemption proceeds of any of those shares
purchased on or after May 1, 1997 that are redeemed  within 12 months of the end
of the calendar month of their purchase. That sales charge will be equal to 1.0%
of the lesser of (1) the aggregate  net asset value of the redeemed  shares (not
including  shares  purchased  by  reinvestment  of  dividends  or  capital  gain
distributions) or (2) the original price (which is the original net asset value)
of the redeemed shares.  However,  the Class A contingent  deferred sales charge
will not exceed the aggregate  amount of the commissions the Distributor paid to
your dealer on all Class A shares of all Oppenheimer funds you purchased subject
to the Class A contingent deferred sales charge.
    

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

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

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

                                     -31-

Builder Plans for their clients.

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

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

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

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

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

      Waivers of Initial and Contingent Deferred Sales Charges for
Certain Purchasers.  Class A shares purchased by the following

                                     -32-

      o dealers,  brokers,  banks, or registered  investment  advisers that have
entered into an agreement with the  Distributor (1) providing  specifically  for

transaction  fee by their  dealer,  broker,  bank or adviser for the purchase or
sale of Fund  shares)  or (2)  that  have  entered  into an  agreement  with the
Distributor to sell shares to defined contribution employee retirement plans for
which the dealer, broker or investment adviser provides administration services;

      o (1) investment  advisors and financial planners who have entered into an
agreement  for this  purpose  with the  Distributor  and who charge an advisory,

plans and  trusts  used to fund  those  Plans  (including,  for  example,  plans
qualified  or  created  under  sections  401(a),  403(b) or 457 of the  Internal
Revenue  Code),  and "rabbi  trusts" that buy shares for their own accounts,  in

appropriate agreement with the Distributor;

      o a  TRAC-2000  401(k)  plan  (sponsored  by the  former  Quest  for Value

consummated and share purchases commenced by December 31, 1996.
    

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

      o shares  issued  in  plans  of  reorganization,  such as  mergers,  asset
acquisitions and exchange offers, to which the Fund is a party;

   
      o shares purchased by the reinvestment of loan repayments by a participant

      o shares  purchased  and paid for with the proceeds of shares  redeemed in
the prior 30 days from a mutual fund  (other than a fund  managed by the Manager
or any of its subsidiaries) on which an initial sales charge or contingent sales
charge was paid (this  waiver also  applies to shares  purchased  by exchange of
shares of Oppenheimer  Money Market Fund,  Inc. that were purchased and paid for
in this manner), this waiver must be requested when the purchase order is placed
for your shares of the Fund, and the  Distributor  may require  evidence of your
qualification for this waiver; or
    

      o shares purchased with the proceeds of maturing principal of units of any

are redeemed in the following cases:

      o to make Automatic  Withdrawal Plan payments that are limited annually to
no more than 12% of the original account value;

      o  involuntary  redemptions  of shares by operation of law or  involuntary

will be payable if the shares are redeemed within 18 months of purchase);

      o if,  at the time of  purchase  of shares  (on or after May 1,  1997) the

fund (other than a fund managed by the Manager or its subsidiary)  offered as an
investment  option  in a  Retirement  Plan in which  Oppenheimer  funds are also
offered as investment options under a special  arrangement with the Distributor;
or (11)  plan  termination  or  "in-service  distributions,"  if the  redemption
proceeds are rolled over directly to an OppenheimerFunds-sponsored IRA;

      o for  distributions  from  Retirement  plans having 500 or more  eligible
participants,  except distributions due to termination of all of the Oppenheimer
funds as an investment option under the Plan; and

      o for  distributions  from 401(k) plans sponsored by  broker-dealers  that
have entered into a special agreement with the Distributor allowing this waiver.
    

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

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

Buying Class B Shares.  Class B shares are sold at net asset value
per share without an initial sales charge. However, if Class B
shares are redeemed within 6 years of their purchase, a contingent

                                     -36-

<PAGE>



deferred sales charge will be deducted from the redemption proceeds.  That sales
charge will not apply to shares  purchased by the  reinvestment  of dividends or
capital gains distributions.  The contingent deferred sales charge will be based
on the  lesser  of the net  asset  value of the  redeemed  shares at the time of
redemption  or the  original  offering  price  (which is the  original net asset
value).  The  contingent  deferred  sales charge is not imposed on the amount of
your  account  value  represented  by the  increase  in net asset value over the
initial purchase price. The Class B contingent  deferred sales charge is paid to
the  Distributor  to reimburse  its  expenses of providing  distribution-related
services to the Fund in connection with the sale of Class B shares.

      To determine  whether the  contingent  deferred  sales charge applies to a
redemption,  the Fund redeems shares in the following order: (1) shares acquired
by  reinvestment of dividends and capital gains  distributions,  (2) shares held
for over 6 years, and (3) shares held the longest during the 6-year period.  The
contingent  deferred sales charge is not imposed in the circumstances  described
in "Waivers of Class B and Class C Sales Charges," below .

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

   
Years Since
Beginning of
Month in which          Contingent Deferred Sales Charge
Purchase Order          On Redemptions in That Year
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.  All purchases are  considered to
have  been  made on the  first  regular  business  day of the month in which the
purchase was made.

      |X| Automatic Conversion of Class B Shares.  72 months after you
purchase Class B shares, those shares will automatically convert to

                                     -37-

<PAGE>



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

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

      To determine  whether the  contingent  deferred  sales charge applies to a
redemption,  the Fund redeems shares in the following order: (1) shares acquired
by  reinvestment of dividends and capital gains  distributions,  (2) shares held
for over 12 months,  and (3) shares held the longest during the 12-month period.
All purchases are considered to have been made on the first regular business day
of the month in which the purchase was made.

   
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
reimburse the Distributor for its services and costs in distributing Class B and
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 that
are outstanding for 6 years or less and on Class C shares.  The Distributor also
receives a service  fee of 0.25% per year under  each  plan.  If either  Plan is
terminated  by the Fund,  the Board of Directors  may allow the Fund to continue
payments of the asset-based  sales charge to the  Distributor  for  distributing
shares before the Plan was terminated.
    

      Under each Plan,  both fees are  computed  on the average of the net asset
value of shares in the respective class, determined as of

                                     -38-

<PAGE>



the close of each regular business day during the period.  The asset-based sales
charge  allows  investors to buy Class B or C shares  without a front-end  sales
charge while  allowing the  Distributor  to  compensate  dealers that sell those
shares.

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

      The Distributor  currently pays sales commissions of 3.75% of the purchase
price of Class B shares to dealers  from its own  resources at the time of sale.
Including  the  advance  of the  service  fee,  the  total  amount  paid  by the
Distributor  to the dealer at the time of sale of Class B shares is 4.00% of the
purchase price. The Fund pays the asset-based sales charge to the Distributor to
reimburse  it for its  services  rendered in  distributing  Class B shares.  The
Distributor retains the asset-based sales charge to recoup the sales commissions
it pays, the advances of service fee payments it makes,  and its financing costs
of distributing and selling Class B shares.

   
      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 1.00% of the
purchase price.  Those payments are retained by the Distributor during the first
year  Class C shares  are  outstanding  to  reimburse  the  Distributor  for its
services rendered in distributing  Class C shares.  The Distributor plans to pay
the asset-based  sales charge as an ongoing  commission to the dealer on Class C
shares that have been outstanding for a year or more.

      The  Distributor's  actual  expenses in selling Class B and Class C shares
may be more than the payments it receives from contingent deferred sales charges
collected  on  redeemed  shares  and from the Fund  under the  Distribution  and
Service Plan for Class B and Class C shares.  At August 31, 1997, the end of the
Class B Plan  year,  the  Distributor  had  incurred  unreimbursed  expenses  in
connection  with sales of Class B shares of  $92,083,482  (equal to 2.78% of the
Fund's net assets  represented  by Class B shares on that  date).  At August 31,
1997,  the  end  of  the  Class  C  Plan  year,  the  Distributor  had  incurred
unreimbursed  expenses in connection  with sales of Class C shares of $7,962,219
(equal to 0.77% of the Fund's net assets  represented  by Class C shares on that
date). If either Plan
    

                                     -39-

<PAGE>



is terminated by the Fund, the Board of Directors may allow the Fund to continue
payments of the asset-based  sales charge to the  Distributor  for  distributing
shares before the Plan was terminated.

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

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

      o distributions to participants or beneficiaries from Retirement plans, if
the  distributions  are made (a) under an  Automatic  Withdrawal  Plan after the
participant  reaches age 59-1/2, as long as the payments are no more than 10% of
the account value  annually  (measured from the date the Transfer Agent receives
the  request),  or (b)  following  the death or  disability  (as  defined in the
Internal  Revenue  Code)  of  the  participant  or  beneficiary  (the  death  or
disability must have occurred after the account was established);

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

      o  returns of excess contributions to Retirement plans;

      o  distributions  from  Retirement  Plans  to  make  "substantially  equal
periodic  payments" as permitted in Section  72(t) of the Internal  Revenue Code
that do not exceed 10% of the account value annually, measured from the date the
Transfer Agent receives the request);

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

      o  distributions  from  OppenheimerFunds  prototype  401(k) plans and from
certain  Massachusetts  Mutual Life Insurance Company prototype 401(k) plans (1)
for hardship  withdrawals;  (2) under a Qualified  Domestic  Relations Order, as
defined in the Internal
    

                                     -40-

<PAGE>



   
Revenue Code; (3) to meet minimum  distribution  requirements  as defined in the
Internal Revenue Code; (4) to make  "substantially  equal periodic  payments" as
described in Section 72(t) of the Internal Revenue Code; (5) for separation from
service; or (6) for loans to participants or beneficiaries; or

      o distributions  from 401(k) plans sponsored by  broker-dealers  that have
entered into a special agreement with the Distributor allowing this waiver.
    

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

      o shares sold to the Manager or its affiliates;

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

      o shares issued in plans of reorganization to which the Fund
is a party.

   
Buying  Class Y Shares.  Class Y shares  are sold at net  asset  value per share
without  sales  charge  directly  to certain  institutional  investors,  such as
insurance companies, registered investment companies and employee benefit plans,
that have  special  agreements  with the  Distributor  for this  purpose.  These
include  Massachusetts  Mutual  Life  Insurance  Company,  an  affiliate  of the
Manager,  which may  purchase  Class Y shares of the Fund and other  Oppenheimer
funds  (as well as Class Y shares  of funds  advised  by  MassMutual)  for asset
allocation  programs,  investment  companies or separate  investment accounts it
sponsors  and  offers to its  customers.  Individual  investors  are not able to
invest in Class Y shares directly.

      While  Class Y shares are not  subject to initial or  contingent  deferred
sales charges or asset-based sales charges, an institutional investor buying the
shares for its  customers'  accounts may impose charges on those  accounts.  The
procedures for purchasing,  redeeming,  exchanging,  or transferring  the Fund's
other  classes of shares  (other than the time those  orders must be received by
the Distributor or Transfer Agent) and the special account features available to
purchasers  of  those  other  classes  of  shares  described  elsewhere  in this
Prospectus  do not  apply  to  Class  Y  shares.  Instructions  for  purchasing,
redeeming,  exchanging or  transferring  Class Y shares must be submitted by the
institutional  investor,  not by its  customers for whose benefit the shares are
held.

Automatic  Withdrawal and Exchange Plans. The Fund has several plans that enable
you to sell shares  automatically  or exchange them to another  Oppenheimer fund
account on a regular basis:

      o Automatic  Withdrawal  Plans.  If your Fund  account is worth  $5,000 or

payments of at least $50 on a monthly,  quarterly,  semi-annual or annual basis.
The checks may be sent to you or sent automatically to your bank account through
AccountLink.  You may even set up certain types of  withdrawals  of up to $1,500
per  month  by  telephone.  You  should  consult  the  Statement  of  Additional
Information for more details.

      o Automatic  Exchange  Plans.  You can  authorize  the  Transfer  Agent to
exchange an amount you  establish in advance  automatically  for shares of up to
five other  Oppenheimer  funds on a monthly,  quarterly,  semi-annual  or annual
basis  under  an  Automatic   Exchange  Plan.  The  minimum  purchase  for  each
Oppenheimer fund account is $25. These exchanges are subject to the terms of the
Exchange Privilege, described below.

redemption  proceeds  in Class A shares of the Fund or other  Oppenheimer  funds
without paying a sales charge. This privilege applies to Class A shares that you

you paid a  contingent  deferred  sales  charge  when you  redeemed  them.  This
privilege  does  not  apply  to  Class  C  shares.  You  must be sure to ask the
Distributor for this privilege when you send your reinvestment  payment.  Please
consult the Statement of Additional Information for more details.

account.  The Distributor offers a number of different retirement plans that can
be used by individuals and employers:

How to Sell Shares

   
You can arrange to take money out of your account by selling (redeeming) some or
all of your shares on any regular  business day. Your shares will be sold at the
next net asset value calculated after your order is received and accepted by the
Transfer  Agent.  The Fund offers you a number of ways to sell your  shares,  in
writing  or by  telephone.  You can also set up  Automatic  Withdrawal  Plans to
redeem shares on a regular  basis,  as described  above.  If you have  questions
about  any of these  procedures,  especially  if you are  redeeming  shares in a
special  situation,  such as due to the death of the owner, or from a Retirement
Plan, please call the Transfer Agent first, at 1-800-525-7048, for assistance.

      o    Retirement     Accounts.     To    sell    shares    held    in    an
OppenheimerFunds-sponsored  retirement  account in your name,  call the Transfer
Agent for a distribution  request form. There are special income tax withholding
requirements  for  distributions  from  Retirement  Plans and you must  submit a
withholding  form with your  request to avoid  delay.  If your  Retirement  Plan
account is held for you by your employer,  you must arrange for the distribution
request to be sent by the plan  administrator  or trustee.  There are additional
details in the Statement of Additional Information.
    

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

   
      o You wish to redeem more than $50,000 worth of shares and
receive a check;
      o The redemption check is not payable to all shareholders
listed on the account statement;
      o The redemption check is not sent to the address of record
on your account statement;
    

                                     -44-

<PAGE>



   
      o Shares are being transferred to a Fund account with a
different owner or name;
      o Shares are redeemed by someone other than the owner(s) (such
as an Executor).

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

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

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

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

      o To redeem shares through a service representative, call
    

                                     -45-

<PAGE>



   
1-800-852-8457, or
      o To redeem shares automatically by PhoneLink, call
1-800-533-3310.

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

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

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

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

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

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:


                                     -46-

<PAGE>



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

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

      Exchanges may be requested in writing or by telephone:

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

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

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

      There are certain exchange policies you should be aware of:

   
      o Shares are normally  redeemed from one fund and purchased into the other
fund in the exchange  transaction on the same regular  business day on which the
Transfer Agent receives an exchange  request that is in proper form by the close
of The New York Stock Exchange that day, which is normally 4:00 P.M., but may be
earlier on some days. However, either fund may delay the purchase of
    

                                     -47-

<PAGE>



shares of the fund you are exchanging  into up to seven days if it determines it
would be disadvantaged by a same-day transfer of the proceeds to buy shares. For
example,  the  receipt  of  multiple  exchange  requests  from  a  dealer  in  a
"market-timing"  strategy  might  require the sale of portfolio  securities at a
time or price disadvantageous to the Fund.

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

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

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

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

Shareholder Account Rules and Policies

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

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

      o Telephone Transaction Privileges for purchases, redemptions
or exchanges may be modified, suspended or terminated by the Fund
at any time.  If an account has more than one owner, the Fund and

                                     -48-

<PAGE>



the  Transfer  Agent may rely on the  instructions  of any one owner.  Telephone
privileges apply to each owner of the account and the dealer  representative  of
record for the account unless and until the Transfer Agent receives cancellation
instructions from an owner of the account.

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

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

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

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

      o Payment for redeemed  shares is made ordinarily in cash and forwarded by
check or through AccountLink (as elected by the shareholder under the redemption
procedures  described  above)  within  seven (7) days after the  Transfer  Agent
receives   redemption   instructions  in  proper  form,   except  under  unusual
circumstances  determined by the Securities and Exchange  Commission delaying or
suspending   such   payments.   For  accounts   registered  in  the  name  of  a
broker/dealer,  payment will be forwarded  within three (3) business  days.  The
Transfer  Agent  may  delay  forwarding  a check or  processing  a  payment  via
AccountLink for recently  purchased shares,  but only until the purchase payment
has cleared. That delay may be
    

                                     -49-

<PAGE>



as much as 10 days from the date the shares  were  purchased.  That delay may be
avoided if you purchase shares by Federal Funds wire, certified check or arrange
with your bank to provide  telephone or written  assurance to the Transfer Agent
that your purchase payment has cleared.

   
      o Involuntary redemptions of small accounts may be made by the Fund if the
account  value has fallen  below $500 for  reasons  other than the fact that the
market value of shares has dropped. In some cases,  involuntary  redemptions may
also be made to repay the Distributor for losses from the  cancellation of share
purchase orders.
    

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

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

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

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

Dividends, Capital Gains and Taxes

Dividends.  The Fund declares dividends separately for Class A, Class B, Class C
and Class Y shares from net investment  income on a quarterly basis and normally
pays those dividends to shareholders in March, June, September and December, but
the Board of Directors  can change that date.  Dividends  paid on Class A shares
and Class Y shares  generally  are  expected  to be higher  than for Class B and
Class C shares  because  expenses  allocable  to Class B and Class C shares will
generally be higher. There is no fixed dividend rate

                                     -50-

<PAGE>



and there can be no assurance as to the payment of any dividends.

Capital Gains. The Fund may make  distributions  annually in December out of any
net short-term or long-term  capital gains,  and the Fund may make  supplemental
distributions  of dividends  and capital  gains  following the end of its fiscal
year.  Short-term  capital  gains are  treated as  dividends  for tax  purposes.
Long-term capital gains will be separately identified in the tax information the
Fund sends you after the end of the calendar  year.  There can be no  assurances
that the Fund will pay any capital gains distributions in a particular year.

   
Distribution  Options.  When you open your account,  specify on your application
how   you   want   to   receive   your   dividends   and   distributions.    For
OppenheimerFunds-sponsored    retirement   accounts,   all   distributions   are
reinvested. For other accounts, you have four options:

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

Taxes. If your account is not a tax-deferred  retirement account,  you should be
aware of the  following  tax  implications  of investing in the Fund.  Long-term
capital  gains are  taxable  as  long-term  capital  gains when  distributed  to
shareholders.  It does not matter how long you have held your shares.  Dividends
paid from  short-term  capital  gains and net  investment  income are taxable as
ordinary  income.  Distributions  are  subject to federal  income tax and may be
subject to state or local  taxes.  Your  distributions  are  taxable  when paid,
whether you reinvest  them in additional  shares or receive them in cash.  Every
year the Fund will send you and the IRS a  statement  showing the amount of each
taxable  distribution  you received in the previous  year. So that the Fund will
not have to pay taxes on the amount it distributes to  shareholders as dividends
and capital  gains,  the Fund intends to manage its  investments so that it will
qualify as a "regulated  investment  company"  under the Internal  Revenue Code,
although the Fund reserves the right not to qualify in a particular year.

      o "Buying a Dividend": If you buy shares on or just before the
    

                                     -51-

<PAGE>



   
ex-dividend date, or just before the Fund declares a capital gains distribution,
you will pay the full  price for the  shares  and then  receive a portion of the
price back as a taxable dividend or capital gain.

      o Taxes on  Transactions:  Share  redemptions,  including  redemptions for
exchanges,  are subject to capital gains tax. Generally,  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.

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

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

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

Class A Sales Charges

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

   
o Purchases by Groups,  Associations and Certain Qualified Retirement Plans. The
following  table sets forth the initial  sales  charge  rates for Class A shares
purchased by a "Qualified  Retirement  Plan" through a single broker,  dealer or
financial  institution,  or by members of "Associations"  formed for any purpose
other than the purchase of securities if that Qualified  Retirement Plan or that
Association  purchased  shares of any of the  Former  Quest  for Value  Funds or
received a proposal to  purchase  such  shares  from OCC  Distributors  prior to
November 24, 1995. For this purpose only, a "Qualified Retirement Plan" includes
any 401(k) plan,  403(b) plan, and SEP-IRA or IRA plan for employees of a single
employer.

 more than 49                 2.00%             2.04%             1.60%


      For purchases by Qualified  Retirement Plans and Associations having 50 or
more  eligible  employees  or  members,  there is no  initial  sales  charge  on
purchases  of Class A  shares,  but  those  shares  are  subject  to the Class A
contingent  deferred  sales  charge  described  on  pages  31  and  32  of  this
Prospectus.

   
      Purchases made under this  arrangement  qualify for the lower of the sales
charge  rate in the  table  based  on the  number  of  eligible  employees  in a
Qualified  Retirement Plan or members of an Association or the sales charge rate
that applies under the Rights of Accumulation described above in the Prospectus.
In  addition,  purchases  by 401(k) plans that are  qualified  retirement  plans
qualify for the waiver of the Class A initial sales charge if they  qualified to
purchase  shares  of any of the  Former  Quest  For  Value  Funds by  virtue  of
projected  contributions  or  investments  of $1  million  or  more  each  year.
Individuals who qualify under this arrangement for reduced sales charge rates as
members of Associations,  or as eligible employees in qualified retirement plans
also may purchase  shares for their  individual  or custodial  accounts at these
reduced sales charge rates, upon request to the Fund's Distributor.
    

o Waiver of Class A Sales  Charges for Certain  Shareholders.  Class A shares of
the Fund  purchased by the  following  investors  are not subject to any Class A
initial or contingent deferred sales charges:

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

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


                                     -54-

<PAGE>




o Waiver of Class A Contingent  Deferred  Sales Charge in Certain  Transactions.
The Class A contingent  deferred  sales charge will not apply to  redemptions of
Class A  shares  of the  Fund  purchased  by the  following  investors  who were
shareholders of any Former Quest for Value Fund:

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

   
      o Participants in qualified  retirement plans that purchased shares of any
of the Former Quest For Value Funds pursuant to a special  "strategic  alliance"
with  the  distributor  of  those  funds.  The  Fund's  Distributor  will  pay a
commission  to the dealer for  purchases  of Fund shares as  described  above in
"Class A Contingent Deferred Sales Charge."
    

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

   
o Waivers for  Redemptions  of Shares  Purchased  Prior to March 6, 1995. In the
following  cases,  the  contingent  deferred  sales  charge  will be waived  for
redemptions of Class A, B or C shares of the Fund acquired by merger of a Former
Quest for Value Fund into the Fund or by exchange from an Oppenheimer  fund that
was a Former  Quest for Value  Fund or into  which  such fund  merged,  if those
shares  were  purchased   prior  to  March  6,  1995:  in  connection  with  (i)
distributions  to participants or beneficiaries of plans qualified under Section
401(a) of the Internal  Revenue Code or from  custodial  accounts  under Section
403(b)(7) of the Code,  Individual  Retirement Accounts,  deferred  compensation
plans under  Section 457 of the Code,  and other  employee  benefit  plans,  and
returns  of excess  contributions  made to each type of plan,  (ii)  withdrawals
under an automatic withdrawal plan holding only either Class B or Class C shares
if the  annual  withdrawal  does  not  exceed  10% of the  initial  value of the
account,  and (iii) liquidation of a shareholder's  account if the aggregate net
asset  value of shares  held in the  account is less than the  required  minimum
value of such accounts.

o Waivers  for  Redemptions  of Shares  Purchased  on or After March 6, 1995 but
Prior to November 24, 1995.  In the following  cases,  the  contingent  deferred
sales  charge  will be waived for  redemptions  of Class A, B or C shares of the
Fund  acquired  by merger of a Former  Quest for Value  Fund into the Fund or by
exchange from an Oppenheimer fund that was a Former Quest For Value Fund or into
which such fund  merged,  if those  shares were  purchased  on or after March 6,
1995, but prior to November 24, 1995: (1) distributions to
    

                                     -55-

<PAGE>



   
participants or beneficiaries from Individual  Retirement Accounts under Section
408(a) of the Internal  Revenue Code or retirement  plans under Section  401(a),
401(k),  403(b) and 457 of the Code, if those  distributions are made either (a)
to an  individual  participant  as a result of  separation  from  service or (b)
following the death or disability (as defined in the Code) of the participant or
beneficiary;  (2) returns of excess  contributions to such retirement plans; (3)
redemptions  other than from retirement  plans following the death or disability
of the  shareholder(s)  (as evidenced by a determination  of total disability by
the U.S. Social  Security  Administration);  (4) withdrawals  under an automatic
withdrawal  plan  (but only for  Class B or Class C  shares)  where  the  annual
withdrawals  do not  exceed 10% of the  initial  value of the  account;  and (5)
liquidation  of a  shareholder's  account if the  aggregate  net asset  value of
shares held in the account is less than the required  minimum  account  value. A
shareholder's  account  will be  credited  with  the  amount  of any  contingent
deferred  sales charge paid on the  redemption  of any Class A, B or C shares of
the Fund described in this section if within 90 days after that redemption,  the
proceeds  are  invested  in the same  Class of shares  in this  Fund or  another
Oppenheimer fund.

                          APPENDIX TO PROSPECTUS OF
                 OPPENHEIMER MAIN STREET INCOME & GROWTH FUND

   
      Graphic material included in the Prospectus of Oppenheimer
Main Street Income & Growth Fund: "Comparison of Total Return of
Oppenheimer Main Street Income & Growth Fund with the S&P 500 Index
- - Change in Value of a $10,000 Hypothetical Investment"

      A linear  graph will be included in the  Prospectus  of  Oppenheimer  Main
Street Income & Growth Fund (the "Fund") depicting the initial account value and
subsequent  account value of a hypothetical  $10,000  investment in the Fund. In
the case of the Fund's  Class A shares,  that  graph will cover the period  from
February 3, 1988  (commencement  of operations)  through August 31, 1997; in the
case of Class B shares the graph will cover the period from the inception of the
class  (October 1, 1994)  through  August 31,  1997;  and in the case of Class C
shares the graph will cover the period from the inception of the class (December
1, 1993)  through  August 31,  1997.  Class Y shares in the graph will cover the
period from the  inception of the class  (November 1, 1996)  through  August 31,
1997). The graphs will compare such values with hypothetical $10,000 investments
over the same  time  periods  in the S&P 500  Index.  Set  forth  below  are the
relevant  data  points  that  will  appear  on  the  linear  graph.   Additional
information  with respect to the  foregoing,  including a description of the S&P

ABOUT THE FUND

Expenses

   
      The Fund pays a variety of expenses directly for management of its assets,
administration,  distribution  of its  shares  and  other  services,  and  those
expenses are subtracted from the Fund's assets to calculate the Fund's net asset
value per share.  All  shareholders  therefore  pay those  expenses  indirectly.
Shareholders  pay other  expenses  directly,  such as sales  charges and account
transaction  charges.  The following  tables are provided to help you understand
your  direct  expenses  of  investing  in the Fund and your  share of the Fund's
operating  expenses that you might expect to bear  indirectly.  The calculations
are based on the Fund's expenses during its fiscal year ended August 31, 1997.

      o  Shareholder  Transaction  Expenses  are charges you pay when you buy or
sell  shares of the Fund.  Please  refer to "About Your  Account"  from pages 24
through 43 for an explanation of how and when these charges apply.

sales charge of up to 1% if you sell your shares  within 12 calendar  months (18
months for shares  purchased  prior to May 1, 1997) from the end of the calendar
month during which you purchased  those shares.  See "How to Buy Shares - Buying
Class A Shares," below.

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

(3) There is a $10 transaction  fee for  redemptions  paid by Federal Funds wire
but not for redemptions paid by check or ACH transfer through  AccountLink.  See
"How to Sell Shares," below.

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

   
        Annual Fund Operating Expenses (as a Percentage of Average Net Assets):

                                        Class A         Class B
                                        Shares          Shares
- -------------------------------------------------------------------------
Management Fees                         .40%             .40%
- -------------------------------------------------------------------------
12b-1 Plan Fees                         None            1.00%
- -------------------------------------------------------------------------
Other Expenses                          .19%             .20%
- -------------------------------------------------------------------------
Total Fund Operating Expenses           .59%            1.60%


       The numbers in the chart above are based of the Fund's business  expenses
in its  fiscal  year  ended  August  31,  1997.  These  amounts  are  shown as a
percentage of the average net assets of each class of the Fund's shares for that
year.  Under  the  Investment  Advisory  Agreement  the Fund  pays  the  Manager
management  fees,  at the annual  rate of 0.55% of net  assets.  Pursuant to the
Agreement,  the Manager has agreed to waive a portion of the fee when the Fund's
net assets are less than $100 million  dollars.  The fee rate,  reflecting  this
waiver,  is 0.40%  when net  assets  are $75  million or more but less than $100
million,  0.25%  when net  assets  are $50  million  or more  but less  than $75
million,  0.15%  when net  assets  are $25  million  or more  but less  than $50
million,  and 0% when net  assets are less than $25  million.  The  Manager  has
voluntarily  undertaken to continue to waive those  expenses over 0.40% when the
net assets of the Fund exceed $100 million.  Without that waiver, the Management
Fee would have been 0.55% for each  class of shares  after the Fund's  total net
assets  exceed  $100  million.  The "12b-1  Distribution  Plan Fees" for Class B
shares are the Distribution and Service Plan Fees (Service fee of 0.25%) and the
asset-based  sales charge of 0.75%. The actual expenses for each class of shares
in future years may be more or less than the numbers in the chart,  depending on
a number of factors,  including the actual amount of the assets  represented  by
each class of shares.
    


      o Examples.  To try to show the effect of these expenses on an
investment over time, we have created the hypothetical examples shown

                                         -4-

<PAGE>



below.  Assume that you make a $1,000  investment in each class of shares of the
Fund,  and that the Fund's annual return is 5%, and that its operating  expenses
for each class are the ones shown in the Annual Fund  Operating  Expenses  chart
above.  If you were to redeem your shares at the end of each period shown below,
your investment would incur the following  expenses by the end of 1, 3, 5 and 10
years:

   
                       1 year      3 years      5 years       10 years(1)
- -------------------------------------------------------------------------
Class A Shares         $53         $66          $79           $118
- -------------------------------------------------------------------------
Class B Shares         $66         $81          $107          $138
    

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

   
Class A Shares         $53         $66          $79           $118
- -------------------------------------------------------------------------
Class B Shares         $16         $51          $87           $138

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

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

A Brief Overview of the Fund

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

      o What is the Fund's Investment Objective? The Fund's investment objective
is to seek as high a level of current  income  which is exempt from  Federal and
California personal income taxes as is available from

                                         -5-

<PAGE>



investing in Municipal Securities while attempting to preserve capital.

      o What Does the Fund Invest In? To seek its investment objective, the Fund
primarily  invests in  investment-grade  municipal  securities,  the interest of
which is exempt from Federal and California  individual income tax. The Fund may
also use hedging instruments and certain derivative investments to try to manage
investment  risks.  These  investments  are more fully  explained in "Investment
Objective and Policies" starting on page 10.

   
      o Who Manages the Fund? The Fund's  investment  adviser (the "Manager") is
OppenheimerFunds, Inc. which (including subsidiaries) manages investment company
portfolios  currently having over $75 billion in assets.  The Manager is paid an
advisory fee by the Fund, based on its assets.  The Fund's portfolio  manager is
Jerry A. Webman, who is employed by the Manager. He is primarily responsible for
the selection of the Fund's securities.  The Fund's Board of Directors,  elected
by  shareholders,  oversees the  investment  adviser and the portfolio  manager.
Please  refer  to  "How  the  Fund is  Managed,"  starting  on page 19 for  more
information about the Manager and its fees.

      o How Risky is the Fund? All investments  carry risks to some degree.  The
Fund's investments in municipal bonds are subject to changes in their value from
a number of factors such as changes in general bond market movements, the change
in value of  particular  bonds  because of an event  affecting  the  issuer,  or
changes in interest rates that can affect bond prices.  These changes affect the
value of the Fund's  investments and its price per share. The fact that the Fund
concentrates  its  investments in California  Municipal  Securities and that the
Fund is permitted to invest in a small  number of issuers  entails  greater risk
than an investment in a diversified investment company. In the Oppenheimer funds
spectrum,  the Fund is generally more  conservative  than high yield bond funds,
but more aggressive  than money market funds.  While the Manager tries to reduce
risks by diversifying  investments,  by carefully researching  securities before
they are purchased  for the Fund's  portfolio and in some cases by using hedging
techniques,  there is no guarantee of success in achieving the Fund's  objective
and your  shares  may be worth more or less than  their  original  cost when you
redeem them.  Please refer to "Investment  Risks" starting on page 11 for a more
complete discussion.

      o How  Can I Buy  Shares?  You can  buy  shares  through  your  dealer  or
financial  institution,   or  you  can  purchase  shares  directly  through  the
Distributor  by completing an  Application  or by using an Automatic  Investment
Plan under AccountLink.  Please refer to "How to Buy Shares" on page 24 for more
details.

      o Will I Pay a Sales  Charge to Buy  Shares?  The Fund has two  classes of
shares. Both classes have the same investment  portfolio but different expenses.
Class A shares are offered with a front-end sales charge, starting at 4.75%, and
reduced for larger purchases. Class B shares are
    

                                         -6-

<PAGE>



   
offered  without a front-end  sales  charge,  but may be subject to a contingent
deferred  sales charge  (starting at 5% and declining as shares are held longer)
if  redeemed  within 6 years of  purchase.  There is also an annual  asset-based
sales charge on Class B shares.  Please  review "How to Buy Shares"  starting on
page 24 for more  details,  including a  discussion  about  factors you and your
financial  advisor should consider in determining which class may be appropriate
for you.

      o How Can I Sell My Shares? Shares can be redeemed by mail or by telephone
call to the Transfer  Agent on any business  day, or through your dealer,  or by
writing a check against your Fund account  (available  for Class A shares only).
Please refer to "How to Sell  Shares" on page 35. The Fund also offers  exchange
privileges to other Oppenheimer funds,  described in "How to Exchange Shares" on
page 38.

      o How Has the Fund Performed? The Fund measures its performance by quoting
its yield,  average  annual  total return and  cumulative  total  return,  which
measure historical performance.  Those yields and returns can be compared to the
yields and returns (over similar periods) of other funds. Of course, other funds
may have  different  objectives,  investments,  and  levels of risk.  The Fund's
performance can also be compared to a broad market index,  which we have done on
page 23.  Please  remember  that  past  performance  does not  guarantee  future
results.

Investment Objective and Policies

Objective. The Fund invests its assets to seek as high a level of current income
which  is  exempt  from  Federal  and  California  personal  income  taxes as is
available  from  investing  in  Municipal   Securities  (defined  below),  while
attempting to preserve capital.

Investment  Policies and  Strategies.  The Fund seeks its objective by following
the fundamental policy of investing,  under normal market  conditions,  at least
80% of its total assets in California Municipal Securities.

    Dividends paid by the Fund derived from interest  attributable to California
Municipal  Securities will be exempt from Federal  individual income taxes. Such
dividends  will also be exempt from  California  personal  income taxes provided
that at the  close of each  quarter,  at least  50% of the  value of the  Fund's
assets are invested in obligations the interest of which is exempt from taxation
under California law when held by an individual. Dividends derived from interest
on Municipal Securities of

                                         -7-

<PAGE>



other  governmental  issuers will be exempt from Federal  individual income tax,
but will be subject to California personal income taxes. Any net interest income
on taxable  investments  and repurchase  agreements  will be taxable as ordinary
income when distributed to shareholders.

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

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

   
    o Portfolio Turnover.  "Portfolio  turnover" describes the rate at which the
fund traded its portfolio  securities  during its last fiscal year. For example,
if a fund sold all of its  securities  during the year,  its portfolio  turnover
rate would have been 100%.  Portfolio  turnover affects brokerage costs the Fund
pays. While short-term trading increases portfolio turnover and may increase the
Fund's  transaction  costs, the Fund incurs little or no brokerage costs because
most of the Fund's portfolio transactions are principal trades without brokerage
commissions.  The Financial  Highlights  table above shows the Fund's  portfolio
turnover rates during prior fiscal years.
    

Investment Risks.

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

   
    Because of the types of  securities  the Fund invests in and the  investment
techniques  the Fund uses,  the Fund is designed for investors who are investing
for the long term. It is not intended for investors
    

                                         -8-

seeking assured income.  While the Manager tries to reduce risks by diversifying
investments,  by carefully researching securities before they are purchased, and
in some cases by using hedging techniques,  changes in overall market prices can
occur at any time,  and because the income  earned on  securities  is subject to
change  there  is no  assurance  that  the  Fund  will  achieve  its  investment
objective. When you redeem your shares, they may be worth more or less than what
you paid for them.

    o Special Considerations - California Municipal Securities. Because the Fund
concentrates  its  investments in California  Municipal  Securities,  the market
value and marketability of such Municipal  Securities and the interest income to
the Fund from them  could be  adversely  affected  by a default  or a  financial
crisis  relating to any of such issuers.  You should  consider  these matters as
well as economic trends in California, summarized in the Statement of Additional
Information  under "Special  Investment  Considerations  - California  Municipal
Securities."
    

    o Interest  Rate  Risks.  In  addition  to credit  risks,  described  below,
Municipal  Securities  are  subject  to  changes  in  value  due to  changes  in
prevailing  interest rates.  When prevailing  interest rates fall, the values of
outstanding  Municipal  Securities generally rise and (if purchased at principal
amount)  would sell at a premium.  Conversely,  when  interest  rates rise,  the
values of outstanding  Municipal  Securities generally decline and (if purchased
at  principal  amount)  would  sell  at  a  discount.  The  magnitude  of  these
fluctuations  will be greater  when the  average  maturity of the  portfolio  is
longer.  Changes  in the  value  of  Municipal  Securities  held  in the  Fund's
portfolio arising from changes in interest rates will not affect interest income
derived  from these  securities,  but will affect the Fund's net asset value per
share.

   
    o Credit  Risks.  Municipal  Securities  are also  subject to credit  risks.
Credit risk relates to the ability of the issuer of a Municipal Security to make
interest or principal  payments on the security as they become due. The economic
and other  factors that can affect that ability are  summarized in the Statement
of Additional  Information under "Special  Investment  Considerations-California
Municipal  Securities."  While  the  Manager  may rely to some  extent on credit
ratings by  nationally  recognized  rating  agencies,  such as Standard & Poor's
Corporation ("Standard & Poor's"), Fitch Investors Service, Inc. ("Fitch"), Duff
& Phelps, Inc. ("Duff & Phelps") or Moody's Investor Services, Inc. ("Moody's"),
in evaluating the credit risk of securities  selected for the Fund's  portfolio,
it may also use its own research and analysis.  However,  many factors affect an
issuer's ability to make timely payments, and there can be no assurance that the
credit risks of a particular security will not change over time.

    o There are special risks in investing in derivative  investments.  The Fund
can  invest in a number  of  different  kinds of  "derivative"  investments.  In
general,  a "derivative  investment" is a specially  designed  investment  whose
performance is linked to the performance of another investment or security, such
as an option, future, index, currency
    

                                         -9-

<PAGE>



   
or commodity.  The company issuing the instrument may fail to pay the amount due
on the maturity of the instrument.  Also, the underlying  investment or security
on which the derivative is based, and the derivative itself, may not perform the
way the  Manager  expects it to  perform.  Markets,  underlying  securities  and
indices may move in a direction not  anticipated by the Manager.  Performance of
derivative  investments may also be influenced by interest rate and stock market
changes in the United States and abroad. All of this can mean that the Fund will
realize less  principal or income from the  investment  than  expected.  Certain
derivative  investments  held by the  Fund  may be  illiquid.  Please  refer  to
"Illiquid and Restricted Securities," below.

    o  Non-diversification.  The  Fund  is  classified  as  a  "non-diversified"
investment  company under the  Investment  Company Act of 1940 (the  "Investment
Company  Act") so that the  proportion of the Fund's assets that may be invested
in the  securities of a single issuer is not limited by the  Investment  Company
Act.  An  investment  in the Fund  therefore  will entail  greater  risk than an
investment in a diversified  investment  company because a higher  percentage of
investments  among fewer issuers may result in greater credit risk exposure to a
smaller number of issuers,  greater fluctuation in the total market value of the
Fund's portfolio, and economic,  political or regulatory developments may have a
greater  impact on the value of the Fund's  portfolio  than would be the case if
the portfolio were diversified among more issuers.  However, the Fund intends to
conduct its operations so as to qualify as a "regulated  investment company" for
purposes of the Internal Revenue Code of 1986, as amended (the "Internal Revenue
Code"),  pursuant  to which:  (1) not more than 25% of the  market  value of the
Fund's total assets will be invested in the securities of a single  issuer,  and
(2) with respect to 50% of the market value of its total  assets,  not more than
5% of the market value of its total assets may be invested in the  securities of
a single  issuer  and the Fund  must  not own more  than 10% of the  outstanding
voting securities of a single issuer.
    

    o Hedging  instruments  can be volatile  investments and may involve special
risks.  The Fund may  invest  in a number  of  hedging  instruments.  The use of
hedging  instruments   requires  special  skills  and  knowledge  of  investment
techniques  that are  different  from  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 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.
Such losses might cause previously  distributed  short-term  capital gains to be
re-characterized as a non-taxable return of capital to shareholders.

    Options trading involves the payment of premiums and has special tax effects
on the Fund. There are also special risks in particular hedging strategies. 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

                                         -10-

the  investment  at the call price and will not be able to realize any profit if
the investment has increased in value above the call price.  If the value of the
investment  does not rise above the call price,  it is likely that the call will
lapse  without being  exercised,  while the Fund keeps the cash premium (and the
investment). 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.  These risks and the hedging  strategies
that the Fund may use are  described  in  greater  detail  in the  Statement  of
Additional Information

Investment Techniques and Strategies.

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

    o Municipal Securities.  Municipal Securities are municipal bonds, municipal
notes and municipal  commercial  paper,  certificates of participation and other
debt obligations issued by or on behalf of the State of California, other states
and the District of Columbia, their political subdivisions, or any commonwealth,
territory or  possession of the United  States,  or their  respective  agencies,
instrumentalities  or  authorities,  the interest from which,  in the opinion of
bond counsel to the  respective  issuer at the time of issue,  is not subject to
Federal individual income tax. California  Municipal  Securities are obligations
of the State of California and its political subdivisions,  and their respective
agencies,  authorities  or  instrumentalities,  the interest from which,  in the
opinion of bond counsel to the  respective  issuer at the time of issue,  is not
includable in gross income for purposes of the California  personal  income tax.
From time to time, the Fund may purchase private activity municipal  securities,
the  interest  from which may be subject to  Federal  alternative  minimum  tax,
although  no  independent  investigation  will be made by the  Manager as to the
users of proceeds of bond offerings or the  application of such proceeds.  It is
anticipated that under normal market conditions,  the Fund's portfolio will have
an average weighted maturity of approximately 7 to 30 years. During periods when
the Fund is  defensively  invested in municipal  notes and municipal  commercial
paper, the average weighted maturity of the Fund's portfolio may decline to 3 to
4 years.

    "Municipal bonds" are Municipal  Securities that have a maturity when issued
of one year or more and "municipal  notes" are Municipal  Securities that have a
maturity when issued of less than one year. The two principal classifications of
Municipal Securities are "general  obligations"  (secured by the issuer's pledge
of its full  faith,  credit and taxing  power for the payment of  principal  and
interest) and "revenue obligations" (payable only from the revenues derived from
a particular facility or class of

                                         -11-

<PAGE>



facilities, or specific excise tax or other revenue source).  The Fund may
invest in Municipal Securities of both classifications.

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

    For temporary defensive purposes, the Fund may invest an unlimited amount of
assets in: (i)  obligations  issued or guaranteed by the U.S.  Government or its
agencies or  instrumentalities;  (ii) cash  equivalents;  (iii) commercial paper
rated in the highest category by an established  rating agency;  (iv) short-term
debt  obligations;  (v) certificates of deposit of domestic banks with assets of
$1  billion  or more;  or (vi)  repurchase  agreements.  To the  extent the Fund
assumes a temporary  defensive position,  a portion of the Fund's  distributions
may be subject to Federal  and state  income  taxes and the Fund may not achieve
its objective.

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

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

    o Inverse Floaters and Other Derivative Investments.  The Fund may

                                         -12-

<PAGE>



   
invest in variable  rate bonds known as  "inverse  floaters."  Yields on inverse
floaters move in the opposite  direction  from  short-term  interest  rates.  As
interest rates rise,  inverse  floaters  produce less current income.  Prices of
inverse floaters may be more volatile than the price of a comparable  fixed-rate
security.  Inverse  floaters  are a type of  "derivative  security,"  which is a
specially designed  investment whose performance is linked to the performance of
another  security or investment.  Some inverse  floaters have a "cap" whereby if
interest  rates  rise above the "cap," the  security  pays  additional  interest
income.  If rates do not rise  above  the  "cap,"  the Fund  will  have  paid an
additional amount for a feature that proves worthless.  The Fund may also invest
in municipal derivative securities that pay interest that depends on an external
pricing  mechanism.  Examples are interest rate swaps or caps and municipal bond
or swap indices.  The Fund  anticipates that it would invest no more than 10% of
its  total  assets  in  inverse  floaters  or such  other  municipal  derivative
securities.  Derivative  Securities  are subject to special  risks  described in
"Investment Risks," above.

    o Ratings of Municipal  Securities.  Municipal  Securities  purchased by the
Fund  must be rated at the  time of  purchase  within  the four  highest  rating
categories  assigned by Moody's,  Standard & Poor's,  Duff & Phelps or Fitch (or
other similar rating organizations) or, if unrated,  judged by the Manager to be
of  comparable  quality to Municipal  Securities  rated within such grades.  See
Appendix A of the Statement of Additional Information for a description of these
ratings.  Investments in unrated Municipal Securities will not exceed 20% of the
Fund's  total  assets.  Not more than 25% of the  Fund's  total  assets  will be
invested in Municipal Securities that are (a) municipal bonds rated either "Baa"
by Moody's or "BBB" by either  Standard  & Poor's,  Fitch or Duff & Phelps,  (b)
municipal notes rated "SP-2" by Standard & Poor's,  "MIG" by Moody's or "F-2" by
Fitch, or (c) if unrated,  Municipal Securities,  judged by the Manager to be of
comparable quality to Municipal  Securities rated within the grades described in
(a) or (b) above, because such Municipal Securities,  although investment grade,
may be subject to greater  market  fluctuations  and risks of loss of income and
principal than higher-rated Municipal Securities,  and may be considered to have
some speculative characteristics.  A reduction in the rating of a security after
its purchase by the Fund will not require the Fund to dispose of such  security.
Securities  that have fallen below  investment  grade entail a greater risk that
the ability of the  issuers of such  securities  to meet their debt  obligations
will be impaired.

    o Borrowing  for  Leverage.  The Fund may not borrow in excess of 10% of the
value  of its  total  assets  and  may do so  only as a  temporary  measure  for
extraordinary  or  emergency  purposes.  Additionally,  the Fund cannot make any
investment when borrowings  exceed 5% of its total assets.  Interest on borrowed
money is an expense  the Fund  would not  otherwise  incur,  so that it may have
substantially  reduced  net  investment  income  during  periods of  substantial
borrowings.  The Fund may borrow only if it  maintains a 300% ratio of assets to
borrowings at all times in the manner set forth in the Investment Company Act.
    

                                         -13-

<PAGE>



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

    o 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.  "When-issued" and "delayed delivery"
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 may be a risk of loss if the value of the
security declines prior to the settlement date.

   
    o  Repurchase  Agreements.  The  Fund  may  acquire  securities  subject  to
repurchase  agreements  to  generate  income,  for  liquidity  purposes  to meet
anticipated  redemptions,  pending the investment of proceeds from sales of Fund
shares,  or pending  settlement  of  purchases of  portfolio  investments.  In a
repurchase transaction,  the Fund buys a security and simultaneously sells it to
the vendor for delivery at a future date.  Repurchase  agreements  must be fully
collateralized.  However,  if the  seller  of the  securities  fails  to pay the
agreed-upon  repurchase price on the delivery date, the Fund's risks may include
any costs of  disposing of the  collateral  for the  agreement,  and losses that
might result from any delays in foreclosing on the collateral.  Income earned on
repurchase transactions is not tax-exempt and, accordingly,  under normal market
conditions,  the Fund will limit its  investments in repurchase  transactions to
20% of its total assets.  When the Fund assumes a temporary  defensive position,
there is no limit on the amount of its assets that may be subject to  repurchase
agreements  maturing  in seven  days or  less.  Repurchase  agreements  having a
maturity beyond seven days are subject to the percentage  limitation on illiquid
and restricted securities,  discussed below. See "Repurchase  Agreements" in the
Statement of Additional Information for more details.

    o Illiquid and  Restricted  Securities.  Under the policies and procedures
established  by the Board of Directors of Oppenheimer  Main Street Funds,  Inc.,
the Manager determines the liquidity of the Fund's investments.  Investments may
be  illiquid  because of the  absence  of an active  trading  market,  making it
difficult to value them or dispose of them  promptly at an acceptable  price.  A
restricted  security is one that has a contractual  restriction on its resale or
which cannot be sold publicly until it is registered under the Securities Act of
1933.  The Fund will not invest  more than 10% of its net assets in  illiquid or
restricted  securities  (the Board may increase  that limit to 15%).  The Fund's
percentage  limitation on these investments does not apply to certain restricted
securities  that are  eligible  for resale to  qualified  institutional  buyers.
Illiquid securities include repurchase agreements
    

                                         -14-

<PAGE>



   
maturing  in more than 7 days,  or certain  participation  interests  other than
those with puts  exercisable  within 7 days.  The Manager  monitors  holdings of
illiquid securities on an ongoing basis and at times the Fund may be required to
sell some holdings to maintain adequate liquidity.

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

    o Loans of Portfolio Securities. To attempt to raise income or to raise cash
for liquidity  purposes,  the Fund may lend its portfolio  securities to certain
types of eligible borrowers  approved by the Board of Directors.  Each loan must
be collateralized in accordance with applicable regulatory  requirements.  After
any loan, the value of the securities loaned must not exceed 25% of the value of
the  Fund's  net  assets.  There are some 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 in the coming year.

   
    o Hedging. The Fund may buy 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 referred to as
"hedging instruments." The Fund does not use hedging instruments for speculative
purposes,  and has  limits  on the use of them,  described  below.  The  hedging
instruments the Fund may use are described below and in greater detail in "Other
Investment   Techniques   and   Strategies"   in  the  Statement  of  Additional
Information.
    

    The Fund may buy and sell options 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,  such as  selling  futures,  buying  puts and
writing covered calls,  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.  Writing  covered call
options may also provide  income to the Fund for liquidity  purposes,  defensive
reasons, or to raise cash to distribute to shareholders.

    o Futures.  The Fund may buy and sell futures  contracts  that relate to (1)
interest  rates  (these are  referred  to as  Interest  Rate  Futures),  and (2)
municipal bond indices (these are referred to as Municipal Bond Index  Futures).
At present, the Fund does not intend to enter into

                                         -15-

<PAGE>



futures contracts and options on futures if, after any such practice, the sum of
margin  deposits on futures and premiums  paid on futures would exceed 5% of the
Fund's total  assets.  These types of Futures are  described in "Hedging" in the
Statement of Additional Information.

   
    o  Put  and  Call  Options.  The  Fund  may  only  buy  exchange-traded  and
over-the-counter  calls only on debt  securities,  broadly-based  municipal bond
indices, Municipal Bond Index Futures and Interest Rate Futures, or to terminate
its  obligation  on a call  the  Fund  previously  wrote.  A call  or put may be
purchased  only if,  after the  purchase,  the value of all call and put options
held by the Fund will not exceed 5% of the Fund's total assets.

    If the Fund sells (that is,  writes) a call  option,  it must be  "covered."
That means the Fund must own the security  subject to the call while the call is
outstanding,  or, for other  types of  written  calls,  the Fund must  segregate
liquid assets to enable it to satisfy its  obligations if the call is exercised.
Up to 25% of the Fund's total assets may be subject to calls. The Fund may write
calls  on  Futures  contracts  it owns,  but  these  calls  must be  covered  by
securities or other liquid  assets the Fund owns and  segregates to enable it to
satisfy its obligations if the call is exercised.

    The Fund may buy puts whether or not it holds the  underlying  investment in
the  portfolio.  If the Fund writes a put, the put must be covered by segregated
liquid  assets.  The Fund will not write puts if more than 25% of the Fund's net
assets would have to be segregated to cover put options.
    

    o Interest Rate Swaps.  In an interest rate swap, the Fund and another party
exchange  their  right to  receive  or their  obligation  to pay  interest  on a
security.  For example,  they may swap a right to receive floating rate payments
for fixed rate payments.  The Fund enters into swaps only on securities it owns.
The Fund may not enter  into  swaps  with  respect to more than 25% of its total
assets.  Also,  the Fund will  segregate  liquid  assets of any type,  including
equity and debt securities of any grade, 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.

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

   
    o The Fund cannot lend money except in connection  with the  acquisition  of
debt securities which the Fund's investment  policies and restrictions permit it
to purchase,  the Fund may also make loans of portfolio  securities,  subject to
the restrictions stated under "Loans of Portfolio Securities"; or

    o The Fund cannot concentrate investments to the extent of 25% of its
    

                                         -16-

<PAGE>



   
assets in any industry, however, there is no limitation as to investment in U.S.
Government  Securities,  Municipal Securities or as to investment in obligations
issued by the State of California or its subdivisions,  agencies, authorities or
instrumentalities,  the Fund cannot invest in securities or any other investment
other than Municipal Securities, temporary investments and Hedging Instruments.

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

How the Fund is Managed

   
Organization  and  History.  The  Fund is one of two  investment  portfolios  or
"series"  of  Oppenheimer  Main  Street  Funds,  Inc.  (the  "Corporation"),  an
open-end,  management  investment company organized as a Maryland corporation in
1987. The Fund commenced operations on May 18, 1990.
    

    The  Corporation  is governed by a Board of Directors,  which is responsible
under Maryland  corporate law for protecting the interests of shareholders.  The
Directors  meet   periodically   throughout  the  year  to  oversee  the  Fund's
activities,  review its  performance,  and review  the  actions of the  Manager.
"Directors  and Officers of the  Corporation"  in the  Statement  of  Additional
Information  names the  Directors  and  officers of the Fund and  provides  more
information about them. 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
Director  or  to  take  other  action   described  in  the  Fund's  Articles  of
Incorporation.

    The Board of  Directors  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 two classes of shares,  Class A and Class B. Both
classes  invest  in the  same  investment  portfolio.  Each  class  has  its own
dividends and distributions and pays certain expenses which may be different for
the different  classes.  Each class may have a different  net asset value.  Each
share  has one vote at  shareholder  meetings,  with  fractional  shares  voting
proportionally on matters submitted to the vote of shareholders.  Shares of each
class may have  separate  voting rights on matters in which the interests of one
class are different  from the interests of another  class,  and only shares of a
particular class vote as a class on matters that affect that class alone.
Shares are freely transferrable.

   
The Manager and Its Affiliates. The Fund is managed by the Manager, which
chooses the Fund's investments and handles its day-to-day business.  The
Manager carries out its duties, subject to the policies established by the
    

                                         -17-

<PAGE>



Board of Directors,  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  adviser  since 1959.  The Manager
(including subsidiaries) currently manages investment companies, including other
Oppenheimer  funds,  with  assets of more than $75 billion as of  September  30,
1997, and with more than 3 million shareholder accounts. The Manager is owned by
Oppenheimer Acquisition Corp., a holding company that is owned in part by senior
officers of the Manager and  controlled by  Massachusetts  Mutual Life Insurance
Company.

    o Portfolio Manager.  The Portfolio Manager of the Fund is Jerry A.
Webman.  He is a Senior Vice President of the Manager.  He has been the
person responsible for the day-to-day management of the Fund's portfolio
since April, 1996. Mr. Webman also serves as an officer and portfolio
manager for other Oppenheimer funds.  Previously, Mr. Webman was a
Managing Director with Prudential Mutual Funds - Investment Management,
Inc.

    o Fees and Expenses.  Under the Investment  Advisory Agreement the Fund pays
the Manager monthly, at the annual rate of 0.55% of net assets.  Pursuant to the
Agreement,  the Manager has agreed to waive a portion of the fee when the Fund's
net assets are less than $100 million  dollars.  The fee rate,  reflecting  this
waiver,  is 0.40%  when net  assets  are $75  million or more but less than $100
million,  0.25%  when net  assets  are $50  million  or more  but less  than $75
million,  0.15%  when net  assets  are $25  million  or more  but less  than $50
million,  and 0% when net  assets are less than $25  million.  The  Manager  has
voluntarily  undertaken to continue to waive those  expenses over 0.40% when the
net assets of the Fund exceed $100 million dollars.  That voluntary  undertaking
may be altered  or  rescinded  at any time.  When asset  level  breakpoints  are
reached,  the fee applies to total net assets of the Fund, not only to assets in
excess of such breakpoint.  The Fund's  management fee for its fiscal year ended
August 31, 1997 was 0.40% of average annual net assets for each class of shares.
    

    The Fund pays expenses  related to its daily  operations,  such as custodian
fees,  Directors'  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.  More
information about the Investment  Advisory Agreement and the other expenses paid
by the Fund is contained in the Statement of Additional Information.

   
    There is also information about the Fund's brokerage policies and
practices in "Brokerage Policies of the Fund" in the Statement of
Additional Information.  That section discusses how brokers and dealers
are selected for the Fund's portfolio transactions.  Because the Fund
    

                                         -18-

<PAGE>



purchases  most of its  portfolio  securities  directly from the sellers and not
through brokers,  it therefore incurs  relatively  little expense for brokerage.
From time to time it may use brokers  when  buying  portfolio  securities.  When
deciding  which  brokers to use,  the  Manager is  permitted  by the  Investment
Advisory  Agreement to consider  whether brokers have sold shares of the Fund or
any other funds for which the Manager serves as investment adviser.

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

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

Performance of the Fund

Explanation  of Performance  Terminology.  The Fund uses several types of yields
and total returns to illustrate its  performance.  The performance of each class
of shares is shown  separately,  because the performance of each class of shares
will usually be different as a result of the  different  kinds of expenses  each
class bears.  These returns and yields measure the performance of a hypothetical
investment in the Fund over various periods,  and do not show the performance of
each  shareholder's  investment  (which will vary if dividends and distributions
are received in cash,  or shares are sold or additional  shares are  purchased).
The Fund's  performance  may be useful to help you see how well your  investment
has done and to compare it to other funds or a market index.

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

    o Total Returns. There are different types of "total returns" used to
measure the Fund's performance.  Total return is the change in value of
a hypothetical investment in the Fund over a given period, assuming that

                                         -19-

<PAGE>



all  dividends  and capital  gains  distributions  are  reinvested in additional
shares. The cumulative total return measures the change in value over the entire
period (for  example,  ten years).  An average  annual  total  return  shows the
average  rate of  return  for  each  year in a period  that  would  produce  the
cumulative  total return over the entire period.  However,  average annual total
returns do not show the Fund's actual year-by-year performance.

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

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

How Has the Fund  Performed?  Below is a discussion by the Manager of the Fund's
performance  during  its fiscal  year  ended  August  31,  1997,  followed  by a
graphical  comparison of the Fund's  performance to an  appropriate  broad-based
market index.

    o  Management's  Discussion  of  Performance.  During the fiscal  year ended
August 31, 1997,  the Fund's  performance  was affected by the volatility in the
bond markets. Because of that volatility, the Fund sought to actively manage its
portfolio  duration,  a measure  of the  portfolio's  sensitivity  to changes in
interest rates. By modestly changing that duration, the Fund was able to benefit
when interest  rates were falling and have some  protection  when interest rates
rose. Because of the strengthening  economy in California,  the Fund was able to
benefit from some  relatively  high-yielding  bonds issued by smaller  municipal
issuers such as school districts that were not rated by the major agencies.
    

                                         -20-

    The Fund was  negatively  affected  by the  strong  economic  conditions  in
California  which  helped to produce  adequate  tax  revenues  for  California's
municipal  borrowers reducing the need to finance deficits in the public market.
This lowered the supply of new Municipal  Securities  and reduced the difference
in the yields between  investment  grade and  below-investment  grade bonds. The
Fund's  policy of seeking to maintain a steady  dividend  for its Class A shares
did not materially affect portfolio management strategies during its last fiscal
year. The Fund's portfolio  holdings,  allocations and strategies are subject to
change.

    o Comparing the Fund's  Performance to the Market. The graphs below show the
performance of a hypothetical  $10,000 investment in each class of shares of the
Fund from the  inception  of the class held through  August 31,  1997,  with all
dividends and capital gains  distributions  reinvested in additional shares. The
graphs reflect the deduction of the 4.75% maximum  initial sales charge on Class
A shares and the applicable contingent deferred sales charge on Class B shares.
    

    Because the Fund  invests in a variety of Municipal  Securities,  the Fund's
performance is compared to the performance of the Lehman Brothers Municipal Bond
Index. The Lehman Brothers Municipal Bond Index is an unmanaged index of a broad
range of investment  grade  municipal  bonds widely regarded as a measure of the
performance of the general municipal bond market. Index performance reflects the
reinvestment  of dividends  but does not consider the effect of capital gains or
transaction  costs, and none of the data below shows the effect of taxes.  While
index  comparisons  may  be  useful  to  provide  a  benchmark  for  the  Fund's
performance, it must be noted that the Fund's investments are not limited to the
securities  in any one  index.  Moreover,  the index  performance  data does not
reflect any assessment of the risk of the investments included in the index.

ABOUT YOUR ACCOUNT

How to Buy Shares

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

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

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


                                         -22-

<PAGE>



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
better  suited to your needs  depends  on a number of  factors  which you should
discuss with your financial advisor.  The Fund's operating costs that apply to a
class of shares and the effect of the  different  types of sales charges on your
investment  will vary your  investment  results  over time.  The most  important
factors  to  consider  are how much you plan to invest  and how long you plan to
hold your investment. If your goals and objectives change over time and you plan
to purchase  additional  shares,  you should re-evaluate those factors to see if
you should consider another class of shares.

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

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

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

      o  Investing  for the  Short  Term.  If you have a  short-term  investment
horizon (that is, you plan to hold your shares for not more than six years), you
should probably  consider  purchasing Class A shares rather than Class B shares,
because of the effect of the Class B  contingent  deferred  sales  charge if you
redeem in less than 7 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 A shares might be more advantageous than Class B shares for

                                         -23-

<PAGE>



investments  of more  than  $100,000  expected  to be held for 5 or 6 years  (or
more). For investments over $250,000 expected to be held 4 to 6 years (or more),
Class A shares may become more  advantageous  than Class B shares.  If investing
$500,000 or more,  Class A shares may be more  advantageous  as your  investment
horizon approaches 3 years or more.

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

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

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

      o Are There  Differences in Account  Features That Matter To You?  Because
some account  features may not be  available  to Class B  shareholders,  such as
checkwriting,  or other features (such as Automatic Withdrawal Plans) may not be
advisable  (because of the effect of the  contingent  deferred sales charge) for
Class B  shareholders,  you  should  carefully  review  how you plan to use your
investment  account  before  deciding  which  class  of  shares  to  buy.  Share
certificates  are not available for Class B shares,  and if you are  considering
using your shares as collateral for a loan, that may be a factor to consider.

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

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

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

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

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

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

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

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

      o  Buying  Shares  Through  OppenheimerFunds   AccountLink.  You  can  use
AccountLink  to link your Fund account  with an account at a U.S.  bank or other
financial  institution that is an Automated Clearing House (ACH) member. You can
then transmit  funds  electronically  to purchase  shares,  to have the Transfer
Agent send redemption proceeds, or to transmit
    

                                         -25-

<PAGE>



dividends and distributions to your bank account.

      Shares are  purchased  for your  account  on  AccountLink  on the  regular
business day the  Distributor  is instructed by you to initiate the ACH transfer
to buy shares. You can provide those instructions automatically,  under an Asset
Builder   Plan,   described   below,   or  by   telephone   instructions   using
OppenheimerFunds PhoneLink, also described below. You should request AccountLink
privileges  on  the  application  or  dealer  settlement  instructions  used  to
establish your account. Please refer to "AccountLink" below for more details.

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

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

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

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

Buying Class A Shares. Class A shares are sold at their offering price, which is
normally net asset value plus an initial sales charge.  However,  in some cases,
described below,  purchases are not subject to an initial sales charge,  and the
offering price will be the net asset value. In some

                                         -26-

<PAGE>



cases,  reduced sales charges may be available,  as described  below. Out of the
amount you  invest,  the Fund  receives  the net asset  value to invest for your
account.  The sales charge varies  depending on the amount of your  purchase.  A
portion of the sales charge may be retained by the  Distributor and allocated to
your dealer as commission.  The current sales charge rates and commissions  paid
to dealers and brokers are as follows:



   
                       Front-End Sales   Front-End Sales
                       Charge as a       Charge as a        Commission as
                       Percentage of     Percentage of      Percentage of
Amount of Purchase     Offering Price    Amount Invested    Offering Price

- ----------------------------------------------------------------------
Less than $50,000      4.75%             4.98%            4.00%
- -----------------------------------------------------------------------
$50,000 or more
but less than
$100,000               4.50%             4.71%            4.00%
- -----------------------------------------------------------------------
$100,000 or more
but less than
$250,000               3.50%             3.63%            3.00%
- -----------------------------------------------------------------------
$250,000 or more
but less than
$500,000               2.50%             2.56%            2.25%
- -----------------------------------------------------------------------
$500,000 or more
but less than
$1 million             2.00%             2.04%            1.80%
    

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

      o Class A Contingent  Deferred  Sales  Charge.  There is no initial  sales
charge  on  purchases  of Class A shares  of any one or more of the  Oppenheimer
funds aggregating $1 million or more.

      The Distributor  pays dealers of record  commissions on those purchases in
an amount equal to 1.0% of purchases.  That  commission will be paid only on the
amount  of those  purchases  in excess of $1  million  that were not  previously
subject to a front-end sales charge and dealer commission.

   
      If you redeem any of those shares  purchased prior to May 1, 1997,  within
18 months  of the end of the  calendar  month of their  purchase,  a  contingent
deferred  sales charge  (called the "Class A contingent  deferred sales charge")
may be deducted  from the  redemption  proceeds.  A Class A contingent  deferred
sales charge may be deducted from the redemption
    

                                         -27-

<PAGE>



proceeds  of any of those  shares  purchased  on or after  May 1,  1997 that are
redeemed  within 12 months of the end of the calendar  month of their  purchase.
That sales charge will be equal to 1.0% of the lesser of (1) the  aggregate  net
asset  value  of  the  redeemed  shares  (not  including   shares  purchased  by
reinvestment  of dividends or capital  gain  distributions)  or (2) the original
offering  price (which is the original net asset value) of the redeemed  shares,
whichever is less.  However,  the Class A contingent  deferred sales charge will
not exceed the aggregate  amount of the commissions the Distributor paid to your
dealer on all Class A shares of all Oppenheimer  funds you purchased  subject to
the Class A contingent deferred sales charge.

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

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

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

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

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

   
      Additionally,  you can add together current purchases of Class A and Class
B shares of the Fund and other Oppenheimer funds to reduce the sales charge rate
that applies to current purchases of Class A shares.  You can also count Class A
and Class B shares of Oppenheimer  funds you previously  purchased subject to an
initial or contingent  deferred sales charge to reduce the sales charge rate for
current  purchases  of  Class A  shares,  provided  that  you  still  hold  your
investment in one of the Oppenheimer  funds. The Distributor will add the value,
at current offering price, of
    

                                         -28-

<PAGE>



   
the shares you  previously  purchased  and currently own to the value of current
purchases to determine the sales charge rate that applies. The Oppenheimer funds
are  listed  in  "Reduced   Sales   Charges"  in  the  Statement  of  Additional
Information,  or a list can be obtained from the Distributor.  The reduced sales
charge will apply only to current  purchases and must be requested  when you buy
your shares.

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

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

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

      o the Manager or its affiliates;

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

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

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

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

                                         -29-

<PAGE>



      o dealers,  brokers,  banks or  registered  investment  advisers that have
entered into an agreement with the Distributor  providing  specifically  for the
use of shares of the Fund in particular  investment  products made  available to
their clients (those  clients may be charged a transaction  fee by their dealer,
broker or adviser for the purchase or sale of Fund shares);

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

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

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

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

      o shares  issued  in  plans  of  reorganization,  such as  mergers,  asset
acquisitions and exchange offers, to which the Fund is a party;

      o shares purchased by the reinvestment of dividends or other distributions
reinvested from the Fund or other Oppenheimer funds (other than Oppenheimer Cash
Reserves) or unit investment  trusts for which  reinvestment  arrangements  have
been made with the Distributor;

   
      o shares  purchased  and paid for with the proceeds of shares  redeemed in
the prior 30 days from a mutual fund  (other than a fund  managed by the Manager
or any of its  subsidiaries)  on which an  initial  sales  charge or  contingent
deferred sales charge was paid (this waiver also applies to shares  purchased by
exchange of shares of  Oppenheimer  Money Market Fund,  Inc. that were purchased
and paid for in this  manner),  this waiver must be requested  when the purchase
order is placed for your  shares of the Fund,  and the  Distributor  may require
evidence of your qualification for this waiver; or
    

      o shares  purchased with the proceeds of maturing  principal  units of any
Qualified Unit Investment Liquid Trust Series.

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

      o to make Automatic Withdrawal Plan payments that are limited

                                         -30-

<PAGE>



annually to no more than 12% of the original account value;

      o  involuntary  redemptions  of shares by operation of law or  involuntary
redemptions  of small  accounts (see  "Shareholder  Account Rules and Policies,"
below);

   
      o if, at the time of purchase of shares  (prior to May 1, 1997) the dealer
agreed in writing  to accept the  dealer's  portion of the sales  commission  in
installments  of 1/18th of the commission  per month (and no further  commission
will be payable if the shares are redeemed within 18 months of purchase); or

      o if,  at the time of  purchase  of shares  (on or after May 1,  1997) the
dealer agrees in writing to accept the dealer's  portion of the sales commission
in installments of 1/12th of the commission per month (and no further commission
will be payable if the shares are redeemed within 12 months of purchase).
    


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

      To determine  whether the  contingent  deferred  sales charge applies to a
redemption,  the Fund redeems shares in the following order: (1) shares acquired
by  reinvestment of dividends and capital gains  distributions,  (2) shares held
for over 6 years, and (3) shares held the longest during the 6-year period.  The
contingent  deferred sales charge is not imposed in the circumstances  described
in "Waivers of Class B Sales Charge," below.

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

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

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

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

      o Distribution and Service Plan for Class B Shares. The Fund has adopted
a Distribution  and Service Plan for Class B shares to reimburse the Distributor
for its  services  and  costs  in  distributing  Class B  shares  and  servicing
accounts.  Under the Plan, the Fund pays the Distributor an annual  "asset-based
sales  charge" of 0.75% per year on Class B shares  that are  outstanding  for 6
years or less.  The  Distributor  also receives a service fee of 0.25% per year.
Both fees are  computed  on the  average  annual  net  assets of Class B shares,
determined as of the close of each regular  business day. The asset-based  sales
charge allows  investors to buy Class B shares without a front-end  sales charge
while allowing the Distributor to compensate dealers that sell Class B shares.

      The Distributor  uses the service fee to compensate  dealers for providing
personal services for accounts that hold Class B shares. Services to be provided
include, among others, answering customer

                                         -32-

<PAGE>



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 asset-based  sales
charge and service fees increase  Class B expenses by up to 1.00% of average net
assets per year.

      The  Distributor  pays the 0.25% service fee to dealers in advance for the
first year after Class B shares  have been sold by the dealer.  After the shares
have been held for a year, the  Distributor  pays the service fee on a quarterly
basis. The Distributor pays sales  commissions of 3.75% of the purchase price to
dealers from its own resources at the time of sale. The Distributor  retains the
asset-based  sales charge to recoup the sales  commissions it pays, the advances
of service fee payments it makes, and its financing or other distribution costs.

   
      Because the Distributor's actual expenses in selling Class B shares may be
more than the  payments it  receives  from  contingent  deferred  sales  charges
collected  on  redeemed  shares  and from the Fund  under the  Distribution  and
Service Plan for Class B shares.  Those expenses may be carried over and paid in
future  years.  At  August  31,  1997,  the end of the  Class B Plan  year,  the
Distributor had incurred unreimbursed expenses in connection with sales of Class
B shares of  $384,028  (equal to .40% of the Fund's net  assets  represented  by
Class B shares on that date).  If the Plan is terminated by the Fund,  the Board
of Directors may allow the Fund to continue  payments of the  asset-based  sales
charge to the Distributor  for certain  expenses it incurred before the Plan was
terminated.

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

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

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

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


                                         -33-

<PAGE>



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

      o shares sold to the Manager or its affiliates;

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

      o shares issued in plans of reorganization to which the Fund is a
party.

Information for more details.

      o Automatic  Exchange  Plans.  You can  authorize  the  Transfer  Agent to
exchange an amount you  establish in advance  automatically  for shares of up to
five other  Oppenheimer  funds on a monthly,  quarterly,  semi-annual  or annual

Oppenheimer  funds account is $25.  These  exchanges are subject to the terms of
the Exchange Privilege, described below.

Reinvestment  Privilege.  If you  redeem  some or all of your Class A or Class B
shares  of the  Fund,  you have up to 6 months  to  reinvest  all or part of the

you paid a contingent  deferred sales charge when you redeemed them. You must be
sure to ask the Distributor  for this privilege when you send your  reinvestment
payment.  Please  consult  the  Statement  of  Additional  Information  for more

How to Sell Shares

   
      You can arrange to take money out of your  account by selling  (redeeming)
some or all of your shares on any regular business day. Your shares will be sold
at the next net asset value calculated after your order is received and accepted
by the Transfer Agent. The Fund offers you a number of ways to sell your shares,
in writing, by using the Fund's checkwriting privilege or by telephone.  You can
also set up Automatic  Withdrawal  Plans to redeem shares on a regular basis, as
described  above.  If you have  questions  about  any of these  procedures,  and
especially if you are redeeming  shares in a special  situation,  such as due to
the death of the owner, please call the Transfer Agent first, at 1-800-525-7048,
for assistance.
    

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

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

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

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

   
      o Your name,
      o The Fund's name,
      o Your Fund account  number (from your  account  statement),  o The dollar
      amount  or  number  of  shares  to  be  redeemed,  o Any  special  payment
      instructions,  o Any share  certificates for the shares you are selling, o
      The signatures of all registered owners exactly as the account is
    

                                         -36-

registered, and
      o Any special requirements or documents requested by the Transfer Agent to
assure proper authorization of the person asking to sell shares.
    

Use the following address for requests by mail:

   Denver, Colorado 80231

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

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

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

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

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

   
      You may also have the Transfer Agent send redemption proceeds of $2,500 or
more by Federal Funds wire to a designated  commercial  bank  account.  The bank
must be a member of the Federal Reserve wire system. There is a $10 fee for each
Federal Funds wire. To place a wire redemption request,  call the Transfer Agent
at  1-800-852-8457.  The wire  will  normally  be  transmitted  on the next bank
business day after the shares are redeemed. There is a possibility that the wire
may be delayed up to seven days to enable the Fund to sell securities to pay the
    

                                         -37-

<PAGE>



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

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

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

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

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

      o Checks must be written for at least $100.

      o Checks  cannot be paid if they are  written  for more than your  account
value.

      Remember: your shares fluctuate in value and you should not write a
check close to the total account value.

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

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

How to Exchange Shares

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


                                         -38-

<PAGE>



      o Shares of the fund selected for exchange must be available for sale
in your state of residence;

      o The Prospectuses of this Fund and the fund whose shares you want
to buy must offer the exchange privilege;

      o You must hold the shares you buy when you establish  your account for at
least 7 days before you can exchange them, after the account is open 7 days, you
can exchange shares every regular business day;

      o You must meet the minimum purchase requirements for the fund you
purchase by exchange;

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

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

      Exchanges may be requested in writing or by telephone:

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

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

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

      There are certain exchange policies you should be aware of:

   
      o Shares are normally  redeemed from one fund and purchased into the other
fund in the exchange  transaction on the same regular  business day on which the
Transfer Agent receives an exchange  request that is in proper form by the close
of The New York Stock Exchange that day, which is normally 4:00 P.M., but may be
earlier on some days. However, either fund
    

                                         -39-

<PAGE>



may delay the purchase of shares of the fund you are exchanging into up to seven
days if it determines it would be  disadvantaged  by a same-day  transfer of the
proceeds to buy shares.  For example,  the receipt of multiple exchange requests
from a dealer in a "market-timing"  strategy might require the sale of portfolio
securities at a time or price disadvantageous to the Fund.

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

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

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

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

Shareholder Account Rules and Policies

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

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

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

                                         -40-

<PAGE>



for the  account  unless  and until the  Transfer  Agent  receives  cancellation
instructions from an owner of the account.

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

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

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

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

      o Payment for redeemed  shares is made ordinarily in cash and forwarded by
check or through AccountLink (as elected by the shareholder under the redemption
procedures  described  above)  within  seven (7) days after the  Transfer  Agent
receives   redemption   instructions  in  proper  form,   except  under  unusual
circumstances  determined by the Securities and Exchange  Commission delaying or
suspending   such   payments.   For  accounts   registered  in  the  name  of  a
broker/dealer,  payment will be forwarded  within three (3) business  days.  The
Transfer  Agent  may  delay  forwarding  a check or  processing  a  payment  via
AccountLink for recently  purchased shares,  but only until the purchase payment
has cleared.  That delay may be as much as 10 days from the date the shares were
purchased.  That delay may be avoided if you  purchase  shares by Federal  Funds
wire,  certified check or arrange with your bank to provide telephone or written
assurance to the Transfer Agent that your purchase payment has cleared.
    

                                         -41-

<PAGE>



   
      o Involuntary redemptions of small accounts may be made by the Fund if the
account  value has fallen  below $500 for  reasons  other than the fact that the
market value of shares has dropped.  In some cases  involuntary  redemptions may
also be made to repay the Distributor for losses from the  cancellation of share
purchase orders.
    

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

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

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

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

Dividends, Capital Gains and Taxes

   
Dividends. The Fund declares dividends separately for Class A and Class B shares
from net tax-exempt  income and/or net investment  income each regular  business
day and pays those dividends to  shareholders  monthly on a date selected by the
Board  of  Directors.  Daily  dividends  will not be  declared  or paid on newly
purchased  shares until Federal Funds (funds credited to a member bank's account
at the Federal  Reserve Bank) are available  from the purchase  payment for such
shares.  The amount of dividends and  distributions  may vary from time to time,
depending upon market conditions,  the composition of the Fund's portfolio,  and
expenses  borne by that  class.  It is  expected  that  distributions  paid with
respect  to Class A shares  will  generally  be  higher  than for Class B shares
because  expenses  allocable to Class B shares will generally be higher.  During
the Fund's fiscal year ended August 31, 1997, the Fund  maintained the practice,
to the extent consistent with the amount of the Fund's net investment income and
other distributable  income, of attempting to pay dividends on Class A shares at
a constant level, although the amount of
    

                                         -42-

<PAGE>



   
such  dividends  was  subject to change  from time to time  depending  on market
conditions,  the  composition of the Fund's  portfolio and expenses borne by the
Fund.  The Board of  Directors  may  change the level of  dividends  at any time
without notice to shareholders.

Capital  Gains.  Although  the Fund does not seek  capital  gains,  the Fund may
realize  capital gains on the sale of portfolio  securities.  If it does, it may
make  distributions  out of any net  short-term  or long-term  capital  gains in
December 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.  Short-term  capital gains are treated as taxable
dividends for tax purposes. There can be no assurance that the Fund will pay any
capital gains distributions in a particular year.
    

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

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

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

                                         -43-

<PAGE>



   
      o "Buying a Dividend:" If you buy shares on or just before Fund declares a
capital gains distribution,  you will pay the full price for the shares and then
receive a portion of the price back as a taxable  capital  gain. If that occurs,
it will be  identified  in the  information  that  the  Fund  sends  you for tax
purposes after the end of the calendar year.
    

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

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

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

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


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

Class A Sales Charges

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

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

  more than 49                2.00%             2.04%             1.60%

   
      For  purchases by  Associations  having 50 or more  eligible  employees or
members,  there is no initial  sales charge on purchases of Class A shares,  but
those  shares  are  subject  to the Class A  contingent  deferred  sales  charge
described on pages 28 and 29 of this Prospectus.
    

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

o Waiver of Class A Sales Charges for Certain Shareholders

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

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

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

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

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

      o Investors who purchased Class A shares from a dealer that is or was

                                         -46-

<PAGE>



not permitted to receive a sales load or redemption fee imposed on a shareholder
with whom that dealer has a fiduciary relationship under the Employee Retirement
Income Security Act of 1974 and regulations adopted under the law.

Class A and Class B Contingent Deferred Sales Charge Waivers

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

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

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

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

Street California Municipal Fund: "Comparison of Total Return of
Oppenheimer Main Street California Municipal Fund and the Lehman Brothers
Municipal Bond Index - Change in Value of a $10,000 Hypothetical
Investment"

      A linear  graph will be included in the  Prospectus  of  Oppenheimer  Main
Street  California  Municipal  Fund (the "Fund")  depicting the initial  account
value and subsequent  account value of a hypothetical  $10,000 investment in the
Fund. In the case of the Fund's Class A shares, that graph will cover the period
from the commencement of the Fund's operations (May 18, 1990) through August 31,
1997 and in the case of Class B shares the graph will cover the period  from the
inception of the class  (October 29, 1993) through  August 31, 1997.  The graphs
will compare such values with  hypothetical  $10,000  investments  over the same
time periods in the Lehman  Brothers  Municipal Bond Index.  Set forth below are
the  relevant  data  points  that will  appear on the linear  graph.  Additional
information with respect to the foregoing, including a description of the Lehman

ABOUT THE FUND

Investment Objective and Policies

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

      o  Foreign  Securities.  "Foreign  securities"  include  equity  and  debt
securities  of companies  organized  under the laws of countries  other than the
United  States and debt  securities  of foreign  governments  that are traded on
foreign  securities  exchanges  or  in  the  foreign  over-the-counter  markets.
Securities  of foreign  issuers  that are  represented  by  American  Depository
Receipts or that are listed on a U.S.  securities exchange or traded in the U.S.
over-the-counter markets are not considered "foreign securities" for the purpose
of the Fund's  investment  allocations,  because they are not subject to many of
the special  considerations  and risks,  discussed below,  that apply to foreign
securities traded and held abroad.

   
      Investing in foreign  securities  offers potential  benefits not available
from  investing  solely  in  securities  of  domestic  issuers,   including  the
opportunity to invest in foreign issuers that appear to offer growth  potential,
or in foreign countries with economic policies or business cycles different from
those of the  U.S.,  or to  reduce  fluctuations  in  portfolio  value by taking
advantage of foreign stock markets that do not move in a manner parallel to U.S.
markets.
    

      o Risks of Foreign  Investing.  Investments in foreign  securities present
special  additional  risks and  considerations  not  typically  associated  with
investments  in  domestic  securities:  reduction  of income by  foreign  taxes;
fluctuation in value of foreign portfolio investments due to changes in currency
rates and control regulations (e.g., currency blockage); transaction charges for
currency  exchange;  lack of public  information about foreign issuers;  lack of
uniform accounting,  auditing and financial  reporting  standards  comparable to
those applicable to domestic  issuers;  less volume on foreign exchanges than on
U.S. exchanges; greater volatility and less liquidity on foreign markets than in
the U.S.; less regulation of foreign  issuers,  stock exchanges and brokers than
in the U.S.;  greater  difficulties  in commencing  lawsuits;  higher  brokerage
commission  rates than in the U.S.;  increased  risks of delays in settlement of
portfolio  transactions  or  loss  of  certificates  for  portfolio  securities;
possibilities  in  some  countries  of  expropriation,   confiscatory  taxation,
political,  financial or social instability or adverse diplomatic  developments;
and unfavorable  differences between the U.S. economy and foreign economies.  In
the past, U.S.  Government  policies have discouraged certain investments abroad
by U.S. investors,  through taxation or other  restrictions,  and it is possible
that such restrictions could be re-imposed.

     o U.S.  Government  Securities.  Obligations of U.S. Government agencies or
instrumentalities  (including  mortgage-backed  securities)  may or  may  not be
guaranteed  or  supported  by the "full faith and credit" of the United  States.
Some are  backed by the right of the  issuer to borrow  from the U.S.  Treasury;
others,  by  discretionary  authority  of the U.S.  Government  to purchase  the
agencies' obligations; while others are supported only by the credit of the

                                     -2-

<PAGE>



instrumentality.  All U.S. Treasury obligations are backed by the full faith and
credit of the United States.  If the securities are not backed by the full faith
and  credit  of the  United  States,  the  owner  of the  securities  must  look
principally  to the agency  issuing the  obligation for repayment and may not be
able to assert a claim against the United States in the event that the agency or
instrumentality  does not meet its  commitment.  The Fund  will  invest  in U.S.
Government  Securities  of such  agencies  and  instrumentalities  only when the
Manager is satisfied  that the credit risk with respect to such  instrumentality
is minimal.

      o Convertible Securities.  While convertible securities are a form of debt
security in many cases,  their  conversion  feature  (allowing  conversion  into
equity securities) causes them to be regarded more as "equity equivalents." As a
result,  the rating  assigned to the security  has less impact on the  Manager's
investment  decision with respect to convertible  securities than in the case of
non-convertible  fixed  income  securities.  To  determine  whether  convertible
securities should be regarded as "equity  equivalents," the Manager examines the
following factors:  (1) whether, at the option of the investor,  the convertible
security  can be  exchanged  for a fixed number of shares of common stock of the
issuer,  (2) whether the issuer of the  convertible  securities has restated its
earnings per share of common stock on a fully  diluted  basis  (considering  the
effect of conversion of the convertible securities), and (3) the extent to which
the convertible security may be a defensive "equity  substitute,"  providing the
ability to participate in any  appreciation  in the price of the issuer's common
stock.

      o Rights and Warrants.  Warrants  basically are options to purchase equity
securities at specific prices valid for a specific period of time.  Their prices
do not  necessarily  move parallel to the prices of the  underlying  securities.
Rights are similar to  warrants,  but  normally  have a short  duration  and are
distributed directly by the issuer to its shareholders. Rights and warrants have
no voting  rights,  receive no dividends  and have no rights with respect to the
assets of the issuer.

      o Investing  in Small,  Unseasoned  Companies.  The  securities  of small,
unseasoned  companies  may have a limited  trading  market,  which may adversely
affect the  Fund's  ability to dispose of them and can reduce the price the Fund
might be able to obtain for them.  If other  investment  companies and investors
that invest in this type of securities  trade the same  securities when the Fund
attempts  to dispose of its  holdings,  the Fund may receive  lower  prices than
might otherwise be obtained, because of the thinner, less liquid market for such
securities.

Other Investment Techniques and Strategies

   
      o  When-Issued  and  Delayed  Delivery  Transactions.  As  stated  in  the
Prospectus,  the Fund may invest in  securities on a  "when-issued"  or "delayed
delivery" basis.  Payment for and delivery of the securities  generally  settles
within 45 days of the date the offer is accepted.  The purchase  price and yield
are fixed at the time the buyer  enters into the  commitment.  During the period
between  purchase and  settlement,  no payment is made by the Fund to the issuer
and no  interest  accrues  to the Fund from the  investment.  However,  the Fund
intends to be as fully  invested as possible and will not invest in  when-issued
securities  if its  income  or net  asset  value  will be  materially  adversely
affected.  At the time the Fund makes the commitment to purchase a security on a
when-issued  basis,  it will record the transaction on its books and reflect the
value of the security in determining its net asset value. It will also segregate
liquid assets of any type including equity and debt securities of any grade
    

                                     -3-

<PAGE>



   
equal  in  value  to  the  commitment  for  the  when-issued  securities.  While
when-issued securities may be sold prior to settlement date, the Fund intends to
acquire the securities upon settlement unless a prior sale appears desirable for
investment reasons.  There is a risk that the yield available in the market when
delivery occurs may be higher than the yield on the security acquired.
    

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

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

      o  Illiquid  and  Restricted  Securities.  To  enable  the  Fund  to  sell
restricted  securities not registered under the Securities Act of 1933, the Fund
may  have  to  cause  those  securities  to  be  registered.   The  expenses  of
registration  of  restricted  securities  may be negotiated by the Fund with the
issuer  at the  time  such  securities  are  purchased  by  the  Fund,  if  such
registration  is required  before such  securities  may be sold  publicly.  When
registration  must be arranged  because the Fund wishes to sell the security,  a
considerable period may elapse between the time the decision is made to sell the
securities and the time the Fund would be permitted to sell them. The Fund would
bear the risks of any downward price  fluctuation  during that period.  The Fund
may also acquire,  through private  placements,  securities  having  contractual
restrictions on their resale, which might limit the Fund's ability to dispose of
such  securities  and might  lower the amount  realizable  upon the sale of such
securities.

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


                                     -4-

<PAGE>

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

      o Hedging.  When  hedging to attempt to protect  against  declines  in the
market value of the Fund's  portfolio,  to permit the Fund to retain  unrealized
gains  in the  value of  portfolio  securities  which  have  appreciated,  or to
facilitate  selling  securities for investment  reasons,  the Fund may: (i) sell
Futures,  (ii) buy puts on such Futures or  securities,  or (iii) write  covered
calls on securities  or Futures.  When hedging to permit the Fund to establish a
position in the  securities  market as a  temporary  substitute  for  purchasing
particular securities (which the Fund will normally purchase, and then terminate
that hedging  position),  or to attempt to protect against the possibility  that
portfolio securities are not fully included in a rise in value of the market the
Fund may: (i) buy Futures,  or (ii) buy calls on such Futures or on  securities.
Normally,  the Fund would then purchase the securities and terminate the hedging
portion.

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

      o Writing Covered Call Options.  As described in the Prospectus,  the Fund
may write covered calls.  When the Fund writes a call, it receives a premium and
agrees to sell the underlying security to a purchaser of a corresponding call on
the same security  during the call period (usually not more than nine months) at
a fixed exercise price (which may differ from the market price of the underlying
security),  regardless of market price changes during the call period.  The Fund
has  retained  the risk of loss  should  the  price of the  underlying  security
decline  during  the call  period,  which may be  offset  to some  extent by the
premium.

      To  terminate  its  obligation  on a call it has  written,  the  Fund  may
purchase a corresponding  call in a "closing purchase  transaction." A profit or
loss will be  realized,  depending  upon  whether  the net of the  amount of the
option transaction costs and the premium previously received on the call written
is more or less than the price of the call subsequently  purchased. A profit may
also be realized if the call expires  unexercised,  because the Fund retains the
underlying  security and the premium  received.  Any such profits are considered
short-term capital gains for Federal income tax purposes,

                                     -5-

<PAGE>



and when  distributed  by the Fund are taxable as ordinary  income.  If the Fund
could not  effect a closing  purchase  transaction  due to lack of a market,  it
would  have to hold  the  callable  securities  until  the call  expired  or was
exercised.

      The Fund may also write calls on Futures without owning a futures contract
or a deliverable bond,  provided that at the time the call is written,  the Fund
covers the call by segregating  in escrow an equivalent  dollar amount 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.  In no
circumstances  would an  exercise  notice  require the Fund to deliver a futures
contract;  it would simply put the Fund in a short  futures  position,  which is
permitted by the Fund's hedging policies.

   
      o Writing Put Options.  A put option on securities gives the purchaser the
right to sell, and the writer the  obligation to buy, the underlying  investment
at the exercise price during the option period. The Fund will not write puts if,
as a result,  more than 25% of the  Fund's net assets  would be  required  to be
segregated to cover such put options. Writing a put covered by segregated liquid
assets equal to the exercise  price of the put has the same  economic  effect to
the Fund as writing a covered call. The premium the Fund receives from writing a
put  option  represents  a  profit,  as  long  as the  price  of the  underlying
investment remains equal to or above the exercise price.  However,  the Fund has
also  assumed  the  obligation  during the option  period to buy the  underlying
investment  from the buyer of the put at the  exercise  price,  even  though the
value of the  investment may fall below the exercise  price.  If the put expires
unexercised,  the Fund (as the writer of the put)  realizes a gain in the amount
of the premium less the transaction costs incurred. If the put is exercised, the
Fund must fulfill its  obligation to purchase the  underlying  investment at the
exercise price,  which will usually exceed the market value of the investment at
that time. In that case, the Fund may incur a loss, equal to the sum of the sale
price of the underlying investment and the premium received minus the sum of the
exercise price and any transaction costs incurred.
    

      When writing put options on  securities,  to secure its  obligation to pay
for the underlying security,  the Fund will deposit in escrow liquid assets with
a  value  equal  to or  greater  than  the  exercise  price  of  the  underlying
securities.  The Fund  therefore  foregoes  the  opportunity  of  investing  the
segregated  assets  or  writing  calls  against  those  assets.  As  long as the
obligation  of the  Fund as the put  writer  continues,  it may be  assigned  an
exercise  notice  by the  broker-dealer  through  whom  such  option  was  sold,
requiring the Fund to take delivery of the underlying  security  against payment
of the exercise  price.  The Fund has no control over when it may be required to
purchase the underlying security, since it may be assigned an exercise notice at
any time prior to the  termination  of its  obligation as the writer of the put.
This  obligation  terminates upon expiration of the put, or such earlier time at
which the Fund effects a closing purchase transaction by purchasing a put of the
same series as that previously sold. Once the Fund has been assigned an exercise
notice, it is thereafter not allowed to effect a closing purchase transaction.

      The Fund may effect a closing purchase  transaction to realize a profit on
an  outstanding  put option it has written or to prevent an underlying  security
from being put. Furthermore,  effecting such a closing purchase transaction will
permit the Fund to write  another  put option to the  extent  that the  exercise
price  thereof is secured by the  deposited  assets,  or to utilize the proceeds
from the sale of such assets for other  investments  by the Fund.  The Fund will
realize a profit or loss from a closing purchase  transaction if the cost of the
transaction is less or more than the premium received from

                                     -6-

<PAGE>



writing the option.  As described above for writing  covered calls,  any and all
such  profits  described  herein from  writing  puts are  considered  short-term
capital gains for Federal tax purposes,  and when  distributed  by the Fund, are
taxable as ordinary income.

      o  Purchasing  Calls  and Puts.  The Fund may  purchase  calls to  protect
against the  possibility  that the Fund's  portfolio will not  participate in an
anticipated rise in the securities market. When the Fund purchases a call (other
than in a closing purchase transaction),  it pays a premium and 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 the call is sold at a profit or if,  during the call period,  the market
price of the  underlying  investment is above the sum of the call price plus the
transaction  costs and the premium paid for the call and the call is  exercised.
If the call is not  exercised  or sold  (whether  or not at a  profit),  it will
become  worthless  at its  expiration  date and the Fund will  lose its  premium
payment  and the right to  purchase  the  underlying  investment.  When the Fund
purchases a put, it pays a premium  and,  except as to puts on indices,  has the
right to sell the underlying  investment to a seller of a put on a corresponding
investment  during the put  period at a fixed  exercise  price.  Buying a put on
securities  or  Futures  the Fund owns  enables  the Fund to  attempt to protect
itself  during the put period  against a decline in the value of the  underlying
investment below the exercise price by selling the underlying  investment at the
exercise  price to a seller of a  corresponding  put. If the market price of the
underlying  investment is equal to or above the exercise price and, as a result,
the put is not  exercised  or  resold,  the put  will  become  worthless  at its
expiration date and the Fund will lose its premium payment and the right to sell
the underlying  investment;  the put may,  however,  be sold prior to expiration
(whether or not at a profit).

   
      When the Fund  purchases  a call or put on an index or  Future,  it pays a
premium,  but  settlement  is in cash rather than by delivery of the  underlying
investment to the Fund. Gain or loss depends on changes in the index in question
(and thus on price movements in the securities  market generally) rather than on
price movements in individual securities or futures contracts.
    

      o Options on Foreign  Currencies.  The Fund  intends to write and purchase
calls and puts on foreign  currencies.  The Fund may purchase and write puts and
calls on foreign  currencies  that are  traded on a  securities  or  commodities
exchange or  over-the-counter  markets or are quoted by major recognized dealers
in such options.  It does so to protect against  declines in the dollar value of
foreign  securities  and  against  increases  in  the  dollar  cost  of  foreign
securities to be acquired. If the Manager anticipates a rise in the dollar value
of a foreign currency in which  securities to be acquired are  denominated,  the
increased cost of such securities may be partially offset by purchasing calls or
writing  puts on that  foreign  currency.  If a decline in the dollar value of a
foreign  currency is anticipated,  the decline in value of portfolio  securities
denominated  in that  currency  may be  partially  offset  by  writing  calls or
purchasing puts on that foreign currency. However, in the event of currency rate
fluctuations  adverse to the Fund's position,  it would lose the premium it paid
and transaction costs.

      A call  written on a foreign  currency  by the Fund is covered if the Fund
owns the underlying  foreign currency covered by the call or has an absolute and
immediate  right to  acquire  that  foreign  currency  without  additional  cash
consideration (or for additional cash consideration held in a segregated account
by its Custodian) upon conversion or exchange of other foreign  currency held in
its  portfolio.  A call may be  written  by the Fund on a  foreign  currency  to
provide a hedge against a

                                     -7-

<PAGE>



decline in the U.S.  dollar  value of a security  which the Fund owns or has the
right to acquire and which is denominated in the currency  underlying the option
due to an expected  adverse change in the exchange rate. This is a cross-hedging
strategy. In such circumstances,  the Fund covers the option by maintaining in a
segregated account with the Fund's Custodian, cash or U.S. government securities
or other liquid,  high grade debt  securities in an amount equal to the exercise
price of the option.

      o Futures.  No payment is paid or received by the Fund on the  purchase or
sale of a Future.  Upon  entering into a Futures  transaction,  the Fund will be
required  to deposit an  initial  margin  payment  with the  futures  commission
merchant (the "futures  broker").  The initial  margin payment 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 specified
conditions.  As the Future is marked to market to reflect  changes in its market
value,  subsequent margin payments,  called variation margin, will be paid to or
by the futures  broker on a daily basis.  At any time prior to expiration of the
Future,  if the Fund  elects to close  out its  position  by taking an  opposite
position, a final determination of variation margin is made, and additional cash
is  required  to be paid by or  released  to the Fund.  Any loss or gain is then
realized.   All  futures  transactions  are  effected  through  a  clearinghouse
associated with the exchange on which the contracts are traded.

      o Forward Contracts.  A Forward Contract involves bilateral obligations of
one party to  purchase,  and  another  party to sell,  a specific  currency at a
future date (which may be any fixed number of days from the date of the contract
agreed upon by the parties),  at a price set at the time the contract is entered
into.  These  contracts are traded in the interbank  market  conducted  directly
between currency traders (usually large commercial banks) and their customers.

      The Fund may use Forward  Contracts to protect against  uncertainty in the
level of future exchange rates. The use of Forward  Contracts does not eliminate
fluctuations in the prices of the underlying securities the Fund owns or intends
to acquire, but it does fix a rate of exchange in advance. In addition, although
Forward  Contracts  limit the risk of loss due to a decline  in the value of the
hedged  currencies,  at the same time they limit any  potential  gain that might
result should the value of the currencies increase.

      The Fund may  enter  into  Forward  Contracts  with  respect  to  specific
transactions. For example, when the Fund enters into a contract for the purchase
or sale of a  security  denominated  in a  foreign  currency,  or when  the Fund
anticipates  receipt of dividend  payments in a foreign  currency,  the Fund may
desire to "lock-in"  the U.S.  dollar  price of the security or the U.S.  dollar
equivalent of such payment.  To do so, the Fund enters into a Forward  Contract,
for a fixed  amount  of U.S.  dollars  per  unit of  foreign  currency,  for the
purchase or sale of the amount of foreign  currency  involved in the  underlying
transaction  ("transaction  hedge").  The Fund will  thereby  be able to protect
itself  against  a  possible  loss  resulting  from  an  adverse  change  in the
relationship  between the currency  exchange rates during the period between the
date on which the  security  is  purchased  or sold,  or on which the payment is
declared, and the date on which such payments are made or received.

      The Fund may also use Forward  Contracts to lock in the U.S.  dollar value
of portfolio  positions  ("position  hedge").  In a position hedge, for example,
when the Fund  believes that foreign  currency may suffer a substantial  decline
against the U.S.  dollar,  it may enter into a forward sale  contract to sell an
amount of that foreign currency approximating the value of some or all of the

                                     -8-

<PAGE>



Fund's portfolio securities denominated in such foreign currency.  When the Fund
believes that the U.S. dollar may suffer a substantial decline against a foreign
currency,  it may enter into a forward  purchase  contract  to buy that  foreign
currency for a fixed dollar  amount.  In either  situation  the Fund may, in the
alternative,  enter into a forward contract to sell a different foreign currency
for a fixed U.S.  dollar  amount where the Fund  believes  that the U.S.  dollar
value of the  currency to be sold  pursuant to the  forward  contract  will fall
whenever  there is a decline in the U.S.  dollar  value of the currency in which
portfolio securities of the Fund are denominated ("cross hedge").

      The Fund's  Custodian will identify  liquid assets for a separate  account
having a value  equal to the  aggregate  amount of the Fund's  commitment  under
Forward  Contracts  to cover its short  positions.  The Fund will not enter into
such Forward  Contracts or maintain a net exposure to such  contracts  where the
consummation  of the contracts  would  obligate the Fund to deliver an amount of
foreign  currency in excess of the value of the Fund's  portfolio  securities or
other  assets  denominated  in that  currency  or another  currency  that is the
subject of the hedge. The Fund,  however,  in order to avoid excess transactions
and  transaction  costs,  may  maintain a net  exposure to Forward  Contracts in
excess  of  the  value  of the  Fund's  portfolio  securities  or  other  assets
denominated  in these  currencies  provided  the excess  amount is  "covered" by
liquid securities denominated in any currency, at lest equal at all times to the
amount of such excess.  As an  alternative,  the Fund may purchase a call option
permitting the Fund to purchase the amount of foreign currency being hedged by a
forward sale  contract at a price no higher than the forward  contract  price or
the Fund may  purchase  a put option  permitting  the Fund to sell the amount of
foreign currency  subject to a forward  purchase  contract at a price as high or
higher than the forward contact price.  Unanticipated changes in currency prices
may result in poorer overall performance for the Fund than if it had not entered
into such contracts.

      The precise  matching of the Forward Contract amounts and the value of the
securities  involved will not generally be possible  because the future value of
such  securities in foreign  currencies  will change as a consequence  of market
movements in the value of these securities between the date the Forward Contract
is entered into and the date it is sold.  Accordingly,  it may be necessary  for
the Fund to purchase additional foreign currency on the spot (i.e., cash) market
(and bear the expense of such purchase),  if the market value of the security is
less than the amount of foreign currency the Fund is obligated to deliver and if
a  decision  is made to sell the  security  and  make  delivery  of the  foreign
currency. Conversely, it may be necessary to sell on the spot market some of the
foreign currency received upon the sale of the portfolio  security if its market
value  exceeds the amount of foreign  currency the Fund is obligated to deliver.
The projection of short-term  currency market movements is extremely  difficult,
and  the  successful  execution  of a  short-term  hedging  strategy  is  highly
uncertain.   Forward  Contracts  involve  the  risk  that  anticipated  currency
movements will not be accurately  predicted,  causing the Fund to sustain losses
on these contracts and transactions costs.

      At or before the maturity of a Forward Contract requiring the Fund to sell
a  currency,  the Fund may either  sell a  portfolio  security  and use the sale
proceeds to make  delivery of the currency or retain the security and offset its
contractual  obligation to deliver the currency by purchasing a second  contract
pursuant to which the Fund will  obtain,  on the same  maturity  date,  the same
amount of the currency that it is obligated to deliver.  Similarly, the Fund may
close out a Forward  Contract  requiring it to purchase a specified  currency by
entering into a second contract entitling it to sell the same amount of the same
currency on the maturity date of the first contract. The Fund would realize

                                     -9-

<PAGE>



a gain or loss as a result of entering into such an offsetting  Forward Contract
under either  circumstance  to the extent the exchange rate or rates between the
currencies  involved moved between the execution dates of the first contract and
offsetting contract.

      The cost to the Fund of engaging in Forward  Contracts varies with factors
such as the  currencies  involved,  the  length of the  contract  period and the
market conditions then prevailing. Because Forward Contracts are usually entered
into on a principal  basis,  no fees or commissions  are involved.  Because such
contracts  are not traded on an exchange,  the Fund must evaluate the credit and
performance risk of each particular counterparty under a Forward Contract.

      Although  the Fund values its assets  daily in terms of U.S.  dollars,  it
does not intend to convert its holdings of foreign  currencies into U.S. dollars
on a daily basis.  The Fund may convert foreign  currency from time to time, and
investors should be aware of the costs of currency conversion.  Foreign exchange
dealers do not charge a fee for conversion, but they do seek to realize a profit
based on the  difference  between the prices at which they buy and sell  various
currencies.  Thus, a dealer may offer to sell a foreign  currency to the Fund at
one rate,  while  offering a lesser rate of  exchange  should the Fund desire to
resell that currency to the dealer.

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

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

      o Additional  Information  About  Hedging  Instruments  and Their Use. The
Corporation'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 securities on which the Fund has written
options or as to other acceptable escrow  securities,  so that no margin will be
required  for  such  transactions.  OCC  will  release  the  securities  on  the
expiration of the option or upon
    

                                     -10-

<PAGE>



the Fund's  entering into a closing  transaction.  The Fund cannot issue "senior
securities",  but this does not prohibit it from borrowing money as described in
the prospectus,  or entering into margin,  collateral or escrow  arrangements as
permitted by its other invest policies.

   
      When the Fund writes an over-the-counter  ("OTC") option, it will normally
enter into an  arrangement  with a primary U.S.  Government  securities  dealer,
which would  establish a formula price at which the Fund would have the absolute
right to repurchase that OTC option. This 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
("in-the-money").  For any OTC option the Fund writes, it will treat as illiquid
(for  purposes  of  the  restriction  on  illiquid  securities,  stated  in  the
Prospectus)  the  mark-to-market  value  of any OTC  option  held by it,  unless
subject to a buy-back agreement with the executing broker. The SEC is evaluating
the general  issue of whether or not OTC options  should be considered as liquid
securities,  and the procedure  described above could be affected by the outcome
of that evaluation.
    

      An option  position  may be  closed  out only on a market  which  provides
secondary trading for options of the same series, and there is no assurance that
a liquid  secondary  market  will exist for any  particular  option.  The Fund's
option  activities may affect its 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 in a manner beyond the
Fund's  control.  The exercise by the Fund of puts on  securities or Futures may
cause the sale of  related  investments,  also  increasing  portfolio  turnover.
Although such exercise is within the Fund's  control,  holding a put might cause
the Fund to sell the underlying  investment for reasons which would not exist in
the absence of the put.  The Fund will pay a brokerage  commission  each time it
buys or sells a call, a put or an underlying  investment in connection  with the
exercise of a put or call. Such commissions may be higher,  on a relative basis,
than those  which  would apply to direct  purchases  or sales of the  underlying
investments. Premiums paid for options are small in relation to the market value
of such investments and  consequently,  put and call options offer large amounts
of  leverage.  The  leverage  offered by trading in options  could result in the
Fund's  net asset  value  being  more  sensitive  to changes in the value of the
underlying investment.

      o  Regulatory  Aspects of Hedging  Instruments.  The Fund is  required  to
operate within certain  guidelines and  restrictions  with respect to the use of
Futures as established by the Commodities  Futures Trading Commission  ("CFTC").
In  particular,  the Fund is excluded  from  registration  as a "commodity  pool
operator" if it complies with the  requirements of Rule 4.5 adopted by the CFTC.
The Rule does not limit the percentage of the Fund's assets that may be used for
Futures margin and related  options  premiums for a bona fide hedging  position.
However,  under the Rule,  the Fund must  limit its  aggregate  initial  futures
margin and related 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 must also, as to its short  positions,
use Futures and options thereon solely for bona fine hedging purposes within the
meaning and intent of the applicable provisions of the CEA.

      Transactions in options by the Fund are subject to limitations established
by option exchanges  governing the maximum number of options that may be written
or held by a single investor or group of investors acting in concert, regardless
of whether the options were written or purchased on the

                                     -11-

<PAGE>



same or different  exchanges or are held in one or more  accounts or through one
or more different  exchanges or through one or more brokers.  Thus the number of
options  which the Fund may write or hold may be affected by options  written or
held by other entities,  including other  investment  companies  having the same
adviser as the Fund (or an adviser that is an affiliate of the Fund's  adviser).
The exchanges also impose position limits on Futures  transactions.  An exchange
may order the  liquidation of positions found to be in violation of those limits
and may impose certain other sanctions. Due to requirements under the Investment
Company Act of 1940 (the  "Investment  Company Act"),  when the Fund purchases a
Future,  the Fund will  maintain in a  segregated  account or accounts  with its
Custodian,  liquid  assets  in an  amount  equal  to  the  market  value  of the
securities underlying such Future, less the margin deposit applicable to it.

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

      Certain foreign currency exchange contracts ("Forward Contracts") in which
the Fund may invest are treated as  "section  1256  contracts."  Gains or losses
relating  to  section  1256  contracts  generally  are  characterized  under the
Internal  Revenue Code as 60%  long-term  and 40%  short-term  capital  gains or
losses.  However,  foreign currency gains or losses arising from certain section
1256 contracts  (including Forward Contracts)  generally are treated as ordinary
income or loss. In addition,  section 1256 contracts held by the Fund at the end
of each  taxable  year are  "marked-to-market"  with the result that  unrealized
gains or losses are treated as though they were realized.  These  contracts also
may be marked-to-market  for purposes of the excise tax applicable to investment
company  distributions and for other purposes under rules prescribed pursuant to
the Internal  Revenue  Code. An election can be made by the Fund to exempt these
transactions from this marked-to-market treatment.

   
      Certain  Forward  Contracts  entered  into  by  the  Fund  may  result  in
"straddles"  for Federal income tax purposes.  The straddle rules may affect the
character  and timing of gains (or  losses)  recognized  by the Fund on straddle
positions.  Generally,  a loss sustained on the disposition of a position making
up a straddle is allowed only to the extent such loss  exceeds any  unrecognized
gain in the  offsetting  positions  making up the straddle.  Disallowed  loss is
generally  allowed  at the  point  where  there is no  unrecognized  gain in the
offsetting  positions  making up the  straddle,  or the  offsetting  position is
disposed of.
    

      Under  the  Internal  Revenue  Code,  gains  or  losses   attributable  to
fluctuations  in exchange  rates that occur  between  the time the Fund  accrues
interest  or  other   receivables  or  accrues  expenses  or  other  liabilities
denominated in a foreign  currency and the time the Fund actually  collects such
receivables or pays such liabilities generally are treated as ordinary income or
ordinary loss.  Similarly,  on disposition of debt  securities  denominated in a
foreign currency and on disposition of foreign currency forward contracts, gains
or losses  attributable  to  fluctuations  in the  value of a  foreign  currency
between the date of  acquisition  of the  security  or contract  and the date of
disposition also

                                     -12-

<PAGE>



are  treated  as  ordinary  gain or loss.  Currency  gains and losses are offset
against market gains and losses on each trade before  determining a net "Section
988" gain or loss under the  Internal  Revenue  Code for that  trade,  which may
increase  or  decrease  the  amount  of the  Fund's  investment  company  income
available for distribution to its shareholders.

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

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

      If the Fund uses  hedging  instruments  to  establish  a  position  in the
securities  markets as a temporary  substitute  for the  purchase of  individual
securities  (long  hedging)  by buying  Futures  and/or  calls on such  Futures,
broadly-based  indices  or on  securities,  it is  possible  that the market may
decline.  If the Fund then  concludes  not to invest in  securities at that time
because of concerns as to possible  further market decline or for other reasons,
it will  realize  a loss on the  hedging  instruments  that is not  offset  by a
reduction in the price of the securities purchased.  In the future, the Fund may
employ hedging  instruments and strategies  that are not presently  contemplated
but which may be developed, to the extent such investment methods are consistent
with the Fund's  investment  objective,  are legally  permissible and adequately
disclosed.

Other Investment Restrictions

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

      Under these additional restrictions:

      o The  Fund  cannot  invest  in  interests  in oil or gas  exploration  or
development  programs or in commodities;  however, the Fund may buy and sell any
of the  hedging  instruments  that it may use as  permitted  by any of its other
policies, whether or not such hedging instrument is considered to be a commodity
or commodity contract;

      o The Fund cannot  invest in real estate or in  interests  in real estate;
however,  the Fund may  purchase  securities  of issuers  holding real estate or
interests therein (including securities of real estate investment trusts);

      o The Fund cannot  purchase  securities on margin;  however,  the Fund may
make  margin  deposits  in  connection  with the use of hedging  instruments  as
permitted by any of its other policies;

     o The Fund cannot invest in companies for the purpose of acquiring  control
or management thereof;

      o The Fund cannot underwrite securities of other companies, except insofar
as it might be deemed to be an underwriter for purposes of the Securities Act in
the resale of any securities held in its own portfolio;

      o The  Fund  cannot  invest  or hold  securities  of any  issuer  if those
officers and directors of the  Corporation  or its adviser  owning  individually
more than 1/2 of 1% of the  securities of such issuer  together own more than 5%
of the securities of such issuer;

      o The Fund cannot invest in other open-end investment companies, or invest
more than 5% of its net assets  through  open  market  purchases  in  closed-end
investment companies,  including small business investment  companies,  nor make
any  such  investments  at  commission  rates  in  excess  of  normal  brokerage
commissions;

      o The Fund cannot issue "senior securities," but this does not prohibit it
from borrowing  money as described in the  Prospectus,  or entering into margin,
collateral,  segregation or escrow arrangements,  or options,  futures,  hedging
transactions or other investments as permitted by its other investment policies;
or


                                     -14-

<PAGE>



      o The Fund cannot  pledge,  mortgage or  otherwise  encumber,  transfer or
assign any of its assets to secure a debt;  collateral  arrangements for premium
and margin payments in connection with hedging  instruments are not deemed to be
a pledge of assets.

      For  purposes  of the  Fund's  policy  not to  concentrate  its  assets as
described in the Prospectus,  the Fund has adopted the industry  classifications
set forth in Appendix B to this Statement of Additional Information. This is not
a fundamental policy.

How the Fund is Managed

Organization and History. Oppenheimer Main Street Income & Growth Fund (referred
to as the "Fund") is one of two series of  Oppenheimer  Main Street Funds,  Inc.
(the  "Corporation"),  a Maryland  corporation.  This  Statement  of  Additional
Information  may be used with the Fund's  Prospectus only to offer shares of the
Fund.

   
      Each share of the Fund represents an interest in the Fund  proportionately
equal to the  interest  of each other share of the same class and  entitles  the
holder to one vote per share (and a fractional  vote for a fractional  share) on
matters submitted to their vote at a shareholders' meeting.  Shareholders of the
Fund and of the  Corporation's  other series vote  together in the  aggregate on
certain matters at shareholders' meetings, such as the election of Directors and
ratification  of appointment of auditors of the  Corporation.  Shareholders of a
particular series or class vote separately on proposals which affect that series
or class,  and  shareholders  of a series or class which is not affected by that
matter are not entitled to vote on the proposal.  For example, only shareholders
of a series, such as the Fund, vote exclusively on any material amendment to the
investment advisory agreement with respect to the series. Only shareholders of a
class of a series vote on certain amendments to the Distribution  and/or Service
Plans if the amendments affect that class.
    

      The Directors  are  authorized to create new series and classes of shares.
The Directors may reclassify unissued shares of the Corporation or its series or
classes into  additional  series or classes of shares.  The  Directors  may also
divide or  combine  the  shares of a class  into a greater  or lesser  number of
shares  without  thereby  changing the  proportionate  beneficial  interest of a
shareholder  in the  Fund.  Shares  do not  have  cumulative  voting  rights  or
preemptive or subscription rights. Shares may be voted in person or by proxy.

      It is not contemplated  that regular annual  shareholder  meetings will be
held.  The Fund will hold  meetings  when  required  to do so by the  Investment
Company Act or other applicable law, or when a shareholder  meeting is called by
the  Directors  or  upon  proper  request  of the  shareholders.  A  meeting  of
shareholders  will be called for a specified  purpose (which may include removal
of a Director) upon the written request of the record holders of at least 25% of
the  outstanding  shares  eligible  to be  voted at that  meeting.  The Fund has
undertaken  that it will then  either give the  applicants  access to the Fund's
shareholder list or mail the applicants' communication to all other shareholders
at the applicants' expense.

- ------------------------
1 For the 1996 calendar year. 2 Committee positions effective July 1, 1997.
3 Prior to July 1, 1997,  Messrs.  Conrad and Kirchner  were also members of the
Audit and Review Committee.

Deferred  Compensation  Plan.  The Board of  Directors  has  adopted a  Deferred
Compensation Plan for disinterested  trustees that enable 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  Director  is
periodically adjusted as though an equivalent amount had been invested in shares
of one or more Oppenheimer funds elected by the Director. The amount paid to the
Director under the plan
    

                                     -20-

<PAGE>



   
will be determined based upon the performance of the selected funds. Deferral of
Director's  fees under the plan will not  materially  affect the Fund's  assets,
liabilities  and net income per share.  The plan will not  obligate  the fund to
retain  the  services  of  any  Director  or to  pay  any  particular  level  of
compensation to any Director.  Pursuant to an Order issued by the Securities and
Exchange  Commission,  the Fund may invest in the funds selected by the Director
under  the  plan  without  shareholder  approval  for  the  limited  purpose  of
determining the value of the Director's deferred fee account.

    o Major Shareholders.  As of November 21, 1997 the only persons who owned of
record or was  known by the Fund to own  beneficially  5% or more of the  Fund's
outstanding Class A, Class B, Class C or Class Y shares was Merrill Lynch Pierce
Fenner & Smith, Inc., 4800 Deer Lake Dr. E Floor 3, Jacksonville,  FL 32246, who
owned  10,090,104.863  Class B shares  (representing  approximately 9.79% of the
Fund's  then  outstanding  Class  B  shares),   7,609,771.216   Class  C  shares
(representing  approximately  24.50%  of the  Fund's  then  outstanding  Class C
shares) and Mass Mutual Life Insurance Co., 1295 State Street,  Springfield,  MA
01111, who owned  655,561.172  Class Y shares  (representing  100% of the Fund's
then outstanding Class Y shares).

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

    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.

    o The  Investment  Advisory  Agreement.  The investment  advisory  agreement
between the  Manager  and the  Corporation  on behalf of the Fund  requires  the
Manager,  at its  expense,  to  provide  the Fund with  adequate  office  space,
facilities  and equipment  and to provide and  supervise  the  activities of all
administrative and clerical  personnel  required to provide effective  corporate
administration  for the Fund,  including  the  compilation  and  maintenance  of
records with respect to its operations,  the preparation and filing of specified
reports,  and  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
or by the Distributor under the General Distributor's  Agreement are paid by the
Fund.  The advisory  agreement  lists examples of expenses paid by the Fund, the
major categories of which relate to interest, taxes, brokerage commissions, fees
to certain  Trustees,  legal and audit  expenses,  custodian and transfer  agent
expenses,  share issuance costs,  certain  printing and  registration  costs and
non-recurring  expenses,  including  litigation costs.  During the Fund's fiscal
years ended June 30, 1995 and 1996,  its fiscal period ended August 31, 1996 and
its fiscal year ended  August 31, 1997 the  management  fees paid by the Fund to
the  Manager  were   $8,976,524,   $19,932,096,   $4,428,137  and   $34,036,569,
respectively.
    

    
                                     -21-

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

   
    o The  Distributor.  Under  its  General  Distributor's  Agreement  with the
Corporation,  the Distributor acts as the Corporation's principal underwriter in
the continuous public offering of shares of the Fund's Class A, Class B, Class C
and Class Y shares,  but is not  obligated to sell a specific  number of shares.
Expenses  normally  attributable to sales, are borne by the Distributor.  During
the Fund's  fiscal  years ended June 30, 1995 and 1996 its fiscal  period  ended
August 31, 1996 and its fiscal year ended August 31, 1997, the aggregate  amount
of sales  charges  on  sales  of the  Fund's  Class A  shares  was  $36,545,570,
$34,680,166, $5,372,166 and $25,549,129,  respectively, of which the Distributor
and an affiliated broker-dealer retained $8,951,501,  $8,833,275, $1,443,507 and
$6,671,014, respectively. During the Fund's fiscal years ended June 30, 1995 and
1996,  the fiscal  period ended August 31, 1996 and its fiscal year ended August
31, 1997, the contingent  deferred sales charges collected on the Fund's Class B
shares totaled $393,448, $2,198,614, $594,878 and $5,230,649,  respectively, all
of which the Distributor retained. During the Fund's fiscal years ended June 30,
1995 and 1996, the fiscal period ended August 31, 1996 and its fiscal year ended
August 31, 1997, the contingent  deferred sales charges  collected on the Fund's
Class C shares totaled $233,149,  $204,629, $39,798 and $227,950,  respectively,
all of which the Distributor  retained.  During the fiscal year ended August 31,
1997  commissions  paid to  broker-dealers  by the  Distributor  on sales of the
Fund's  Class  B  and  Class  C  shares  totaled   $38,556,921  and  $2,094,866,
respectively.  Of  those  amounts,  $1,206,092  and  $48,602  were  paid  to  an
affiliated  broker-dealer.  For additional information about distribution of the
Fund's shares and the payments made by the Fund to the Distributor in connection
with such activities, please refer to "Distribution and Service Plans," below.
    

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

Brokerage Policies of the Fund

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

                                     -22-

<PAGE>



or concession paid by the issuer to the underwriter,  and purchases from dealers
include a spread between the bid and asked price.

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

Description  of  Brokerage  Practices  Followed by the  Manager.  Subject to the
provisions of the advisory  agreement,  and the procedures  and rules  described
above,  allocations of brokerage are generally  made by the Manager's  portfolio
traders based upon  recommendations  from the Manager's portfolio  managers.  In
certain  instances,  portfolio  managers may directly  place trades and allocate
brokerage,  also subject to the  provisions  of the advisory  agreement  and the
procedures and rules  described  above.  In either case,  brokerage is allocated
under the  supervision  of the Manager's  executive  officers.  Transactions  in
securities  other than those for which an  exchange  is the  primary  market are
generally done with principals or market makers. In connection with transactions
on  foreign  exchanges,  the  Fund  may  be  required  to  pay  fixed  brokerage
commissions and thereby forego the benefit of negotiated  commissions  available
in  U.S.  markets.  Brokerage  commissions  are  paid  primarily  for  effecting
transactions   in  listed   securities  or  for  certain   fixed-income   agency
transactions in the secondary market,  and are otherwise paid only if it appears
likely that a better price or execution  can be obtained.  When the Fund engages
in an  option  transaction,  ordinarily  the  same  broker  will be used for the
purchase or sale of the option and any  transaction  in the  securities to which
the option  relates.  When possible,  concurrent  orders to purchase or sell the
same  security  by more than one of the  accounts  managed by the Manager or its
affiliates are combined.  The  transactions  effected  pursuant to such combined
orders are averaged as to price and allocated in accordance with the purchase or
sale  orders  actually  placed  for  each  account.  Option  commissions  may be
relatively  higher than those which would apply to direct purchases and sales of
portfolio securities.

    Most  purchases  of  money  market  instruments  and  debt  obligations  are
principal  transactions  at net  prices.  Instead  of using a broker  for  those
transactions,  the Fund normally  deals  directly with the selling or purchasing
principal or market maker unless it determines  that a better price or execution
can  be  obtained  by  using  a  broker.   Purchases  of  these  securities  for
underwriters  include  a  commission  or  concession  paid by the  issuer to the
underwriter.  Purchases from dealers  include a spread between the bid and asked
prices.  The Fund seeks to obtain  prompt  execution of these orders at the most
favorable net price.

    The research  services provided by a particular broker may be useful only to
one or more of the  advisory  accounts of the Manager  and its  affiliates,  and
investment  research received for the commissions of those other accounts may be
useful both to the Fund and one or more of such other  accounts.  Such research,
which may be  supplied by a third  party at the  instance of a broker,  includes
information  and analysis on  particular  companies  and  industries  as well as
market or economic trends and portfolio  strategy,  receipt of market quotations
for portfolio evaluations, information systems,

                                     -23-

<PAGE>



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  Directors  permits  the  Manager  to use
concessions on fixed-price  offerings to obtain research,  in the same manner as
is permitted for agency transactions.  The Board also permits the Manager to use
stated  commissions on secondary  fixed-income  agency trades to obtain research
where the broker has  represented  to the Manager that (i) the trade is not from
or for the broker's own inventory,  (ii) the trade was executed by the broker on
an agency basis at the stated commission,  and (iii) the trade is not a riskless
principal transaction.

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

   
    During the Fund's  fiscal year ended  August 31, 1997,  the total  brokerage
commissions paid by the Fund (not including  spreads or concessions on principal
transactions on a net trade basis) was $10,046,510.  Of that amount, during that
same period, $5,358,032 was paid to brokers as commission in return for research
services.  The transactions  giving rise to those  commissions were allocated in
accordance with the Manager's internal allocation procedures described above.

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

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

     o Average Annual Total Returns.  The "average  annual total return" of each
class  is an  average  annual  compounded  rate of  return  for  each  year in a
specified number of years. It is the rate of return based on the change in value
of a hypothetical initial investment of $1,000 ("P" in the

                                     -24-

formula below) held for a number of years ("n") to achieve an Ending  Redeemable
Value ("ERV") of that investment, according to the following formula.

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

   
    The "average annual total returns" on an investment in Class A shares of the
Fund  (using the method  described  above) for the 1- and 5-year  periods  ended
August 31,  1997 and for the  period  from  February  3, 1988  (commencement  of
operations) to August 31, 1997 were 23.55%, 23.93% and 21.07%, respectively.

    The "average  annual total  return" on Class B shares for the 1-year  period
ended August 31, 1997 and for the period  October 1, 1994  (commencement  of the
public  offering  of the  class) to August  31,  1997 were  25.12%  and  19.85%,
respectively.

    The "average  annual total  return" on Class C shares for the 1-year  period
ended August 31, 1997 and for the period December 1, 1993  (commencement  of the
public  offering  of the  class) to August  31,  1997 were  29.07%  and  16.94%,
respectively.
    

    o Cumulative  Total  Returns.  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

    In calculating  total returns for Class A shares,  the current maximum sales
charge of 5.75% (as a  percentage  of the offering  price) is deducted  from the
initial  investment  ("P")  (unless the return is shown at net asset  value,  as
described below). For Class B shares,  the payment of the applicable  contingent
deferred sales charge (5% for the first year, 4% for the second year, 3% for the
third and fourth years,  2% for the fifth year, 1% for the sixth year,  and none
thereafter) is applied to the investment result for the period shown (unless the
total  return is shown at net asset  value,  as  described  below).  For Class C
shares,  the 1.0% contingent  deferred sales charge is applied to the investment
result for the 1-year  period  (or  less).  Class Y shares are not  subject to a
sales  charge.  Total  returns also assume that all  dividends and capital gains
distributions  during the period are reinvested to buy additional  shares at net
asset  value per share,  and that the  investment  is redeemed at the end of the
period.

   
    The "cumulative total return" on Class A shares for the period from February
3, 1988  (commencement  of  operations)  to August  31,  1997 was  524.01%.  The
"cumulative  total return" on Class B shares for the period from October 1, 1994
(the  commencement  of the  offering of the class)  through  August 31, 1997 was
69.57%.  The  "cumulative  total  return" on Class C shares for the period  from
December 1, 1993 (the  commencement of the offering of the class) through August
31,
    

                                     -25-

<PAGE>



   
1997 was 79.82%.  The Fund's  Class Y shares are not subject to a sales  charge.
The "cumulative  total return" on Class Y shares for the period from November 1,
1996 (the commencement of the offering of the class) through August 31, 1997 was
23.98%.

    o Total  Returns  at Net  Asset  Value.  From time to time the Fund may also
quote an "average annual total return at net asset value" or a "cumulative total
return at net asset value" for Class A, Class B, Class C or Class Y shares. Each
is based on the difference in net asset value per share at the beginning and the
end of the period for a hypothetical investment in that class of shares (without
considering  front-end  or  contingent  deferred  sales  charges) and takes into
consideration the reinvestment of dividends and capital gains distributions. The
"cumulative  total  return at net asset  value" on the Fund's Class A shares for
the period ended August 31, 1997 was 562.08%.  The "cumulative  total return" at
net asset value for the Fund's  Class B shares for the period  ended  August 31,
1997 was 72.57%. The "cumulative total return" at net asset value for the Fund's
Class C shares for the period ended August 31, 1997 was 79.82%.  The "cumulative
total  return" at net asset  value for the Fund's  Class Y shares for the period
ended August 31, 1997 was 23.98%.
    

    Total  return  information  may be  useful to  investors  in  reviewing  the
performance  of the  Fund  and  Class A,  Class  B,  Class C or Class Y  shares.
However, when comparing total return of an investment in shares of the Fund with
that of other  alternatives,  investors should understand that as the Fund is an
equity fund seeking total return which includes capital appreciation, its shares
are subject to greater market risks and  volatility  than shares of funds having
more  conservative  investment  objectives  and  policies  and  that the Fund is
designed  for  investors  who are willing to accept  greater risk of loss in the
hopes of realizing greater gains.

Other  Performance  Comparisons.  From  time to time the Fund  may  publish  the
ranking of its Class A, Class B, Class C or Class Y shares by Lipper  Analytical
Services,   Inc.  ("Lipper"),   a  widely-recognized   independent  mutual  fund
monitoring  service.  Lipper  monitors the  performance of regulated  investment
companies,  including the Fund, and ranks their  performance for various periods
based on categories  relating to investment  objectives.  The performance of the
Fund is ranked  against (i) all other  funds,  (ii) all other  "income & growth"
funds and (iii) all other "income & growth"  funds in a specific size  category.
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.  The Fund  may also  compare  its
performance from time to time with that of Morgan Stanley Capital  International
index,  a capitalized  weighted  index which is widely  utilized as a measure of
world wide stock market performance.

   
    From time to time, the Fund may publish the star ranking of the  performance
of its Class A,  Class B,  Class C or Class Y 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 an  municipal  bond  funds,  based on  risk-adjusted  total
investment  returns.  The Fund is ranked among domestic stock funds.  Investment
return  measures a fund's or class' 1-, 3-, 5- and 10-year  average annual total
returns  (depending  on the  inception of the fund or class) in excess of 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 the fund's
category.  Five stars is the "highest"  ranking (top 10%),  four stars is "above
average" (next 22.5%),  three stars is "average" (next 35%), two stars is "below
average"  (next 22.5%) and one star is "lowest"  (bottom 10%).  The current star
ranking is the fund's or class' 3-year ranking or its combined
    

                                     -26-

<PAGE>



   
3- and 5-year ranking (weighted  60%/40%,  respectively,  or its combined 3-, 5-
and 10-year ranking (weighted 40%, 30% and 30%  respectively),  depending on the
inception of the fund or class.
Rankings are subject to change monthly.

    The Fund may also  compare  its  performance  to that of other  funds in its
Morningstar   Category.   In  addition  to  its  star  rankings,   Morningstar's
classification  may be based on 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.

    The total return on an investment in the Fund's Class A, Class B, Class C or
Class Y shares may be compared with  performance  for the same period of the S&P
500 Index, as described in the Prospectus. The performance of the index includes
a factor  for the  reinvestment  of  income  dividends,  but  does  not  reflect
reinvestment of capital gains,  expenses or taxes. The performance of the Fund's
Class A, Class B, Class C or Class Y shares may also be compared in publications
to (i) the  performance of various market  indices or to other  investments  for
which reliable performance data is available, and (ii) to averages,  performance
rankings or other  benchmarks  prepared by  recognized  mutual fund  statistical
services.
    

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

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

Distribution and Service Plans

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

                                     -27-

<PAGE>



Class C shares,  that vote was cast by the Manager as the sole initial holder of
Class B and Class C shares of the Fund, respectively.


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

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

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

    Under the Plans,  no payment will be made to any Recipient in any quarter if
the  aggregate  net asset  value of all Fund shares  held by the  Recipient  for
itself and its  customers did not exceed a minimum  amount,  if any, that may be
determined  from time to time by a  majority  of the  Corporation's  Independent
Directors.  The Board of Directors  has set the fees at the maximum rate and set
no minimum amount.

   
    For the fiscal year ended  August 31, 1997  payments  under the Class A Plan
totaled $9,363,505,
    

                                     -28-

<PAGE>



   
all of which was paid by the Distributor to Recipients, including $428,606, paid
to an affiliated broker-dealer as reimbursement for Class A personal service and
account  maintenance  services.  For the  fiscal  year ended  August  31,  1997,
payments under the Class B Plan totaled  $26,361,853,  of which the  Distributor
paid  $74,879  to an  affiliated  broker-dealer  as  reimbursement  for  Class B
personal  service  and  maintenance  expenses,  and  retained  $22,635,581,   as
reimbursement for Class B sales commissions and service fee advances, as well as
financing costs.  For the fiscal year ended August 31, 1997,  payments under the
Class C Plan totaled $9,012,625,  of which the Distributor paid $135,581,  to an
affiliated  broker-dealer  as  reimbursement  for Class C personal  service  and
maintenance  expenses,  and retained  $2,838,009,  as reimbursement  for Class C
sales commissions and service fee advances, as well as financing costs.
    

    The Class B and Class C Plans  allow the  service  fee payment to be paid by
the  Distributor  to  Recipients  in advance  for the first year such shares are
outstanding,   and  thereafter  on  a  quarterly  basis,  as  described  in  the
Prospectus.  The advance payment is based on the net asset value of shares sold.
An exchange of shares does not entitle the  Recipient to an advance  service fee
payment.  In the event shares are redeemed during the first year such shares are
outstanding, the Recipient will be obligated to repay a pro rata portion of such
advance payment to the Distributor.

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

    Any  unreimbursed  expenses  incurred with respect to Class A shares for any
fiscal quarter by the Distributor may not be recovered under the Class A Plan in
subsequent fiscal quarters. Payments received by the Distributor under the Class
A Plan will not be used to pay any interest expense,  carrying charges, or other
financial costs, or allocation of overhead by the Distributor.  The Class B Plan
and the Class C Plan allow for the carry-forward of distribution expenses, to be
recovered  from  asset-based  sales charges in  subsequent  fiscal  periods,  as
described  in  the  Prospectus.  The  asset-based  sales  charges  paid  to  the
Distributor by the Fund under the Class B Plan and the Class C Plan are intended
to allow  the  Distributor  to  recoup  the cost of  sales  commissions  paid to
authorized  brokers and dealers at the time of sale,  plus financing  costs,  as
described  in the  Prospectus.  Such  payments  may  also  be  used  to pay  the
Distributor for the following  expenses in connection  with the  distribution of
Class B and Class C shares: (i) financing the advance of the service fee payment
to  Recipients  under the Class B and the Class C Plan,  (ii)  compensation  and
expenses of personnel  employed by the  Distributor to support  distribution  of
Class B and Class C shares, and (iii) costs of sales literature, advertising and
prospectuses  (other than those furnished to current  shareholders)  and certain
other distribution expenses.

<PAGE>



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

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

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

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

B,  Class C and  Class Y shares  of the Fund are  determined  as of the close of
business of The New York Stock  Exchange (the  "Exchange")  on each day that the
Exchange is open, by dividing the value of the Fund's net assets attributable to
that  class by the  number of shares of that  class  outstanding.  The  Exchange
normally  closes at 4:00 P.M. New York time,  but may close earlier on some days
(for  example,  in case of  weather  emergencies  or on days  falling  before  a
holiday).  The Exchange's most recent annual holiday  schedule (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. Trading may
occur in debt  securities and in foreign  securities when the Exchange is closed
(including  weekends and holidays).  Because the Fund's net asset value will not
be calculated at those times,  if  securities  held in the Fund's  portfolio are
traded at such time, the net asset values per share of Class A, Class B, Class C
and  Class Y shares  of the Fund may be  significantly  affected  at times  when
shareholders may not purchase or redeem shares.

    The  Corporation's  Board of Directors has  established  procedures  for the
valuation of the Fund's securities,  generally as follows: (i) equity securities
traded  on a U.S.  securities  exchange  or on the  Automated  Quotation  System
("NASDAQ") of the Nasdaq Stock Market,  Inc. for which last sale  information is
regularly  reported are valued at the last  reported sale price on the principal
exchange for such security or NASDAQ that day (the "Valuation  Date") or, in the
absence  of sales  that day,  at the last  reported  sale  price  preceding  the
Valuation  Date if it is within  the  spread of the  closing  "bid" and  "asked"
prices  on the  Valuation  Date  or,  if not,  the  closing  "bid"  price on the
Valuation Date; (ii) equity securities traded on a foreign  securities  exchange
are valued  generally at the last sales price  available to the pricing  service
approved  by the Fund's  Board of  Trustees or to the Manager as reported by the
principal  exchange on which the security is traded at its last trading  session
on or immediately preceding the Valuation Date, or, if unavailable,  at the mean
between "bid" and "asked"  prices  obtained  from the principal  exchange or two
active market makers in the security on the basis of reasonable inquiry; (iii) a
non-money  market  fund will value (x) debt  instruments  that had a maturity of
more than 397 days when issued,  (y) debt instruments that had a maturity of 397
days or less when issued and have a remaining maturity in excess of 60 days, and
(z) non-money  market type debt  instruments  that had a maturity of 397 days or
less when  issued and have a remaining  maturity  of sixty days or less,  at the
mean between "bid" and "asked" prices  determined by a pricing service  approved
by the Fund's Board of Trustees or, if unavailable, obtained by the Manager from
two active  market  makers in the security on the basis of  reasonable  inquiry;
(iv) money  market-type debt securities held by a non-money market fund that had
a maturity of less than 397 days when issued and have a remaining maturity of 60
days or less,  and debt  instruments  held by a money  market  fund  that have a
remaining  maturity of 397 days or less,  shall be valued at cost,  adjusted for
amortization  of  premiums  and  accretion  of  discount;   and  (v)  securities
(including restricted securities) not having readily-available market quotations
are valued at fair value determined under the Board's procedures. If the Manager
is unable to locate two market makers willing to give quotes (see (ii) and (iii)
above),  the  security  may be priced at the mean  between the "bid" and "asked"
prices  provided by a single  active market maker (which in certain cases may be
the "bid" price if no "asked" price is  available)  provided that the Manager is
satisfied  that the firm  rendering  the quotes is reliable  and that the quotes
reflect the current market value.
    

    In the case of U.S. Government  Securities and  mortgage-backed  securities,
where last sale information is not generally available,  such pricing procedures
may include "matrix" comparisons to

                                     -31-

<PAGE>



the prices for comparable  instruments on the basis of quality,  yield, maturity
and other  special  factors  involved.  The  Manager  may use  pricing  services
approved  by the Board of  Directors  to price  any of the  types of  securities
described above to price U.S. Government Securities, mortgage-backed securities,
foreign government  securities and corporate bonds. The Manager will monitor the
accuracy of such pricing  services,  which may include comparing prices used for
portfolio evaluation to actual sales prices of selected securities.

    Trading in securities on European and Asian  exchanges and  over-the-counter
markets is normally  completed  before the close of the New York Stock Exchange.
Events affecting the values of foreign  securities traded in securities  markets
that occur between the time their prices are determined and the close of the New
York Stock Exchange will not be reflected in the Fund's calculation of net asset
value unless the Board of Directors or the Manager, under procedures established
by the Board of Directors,  determines  that the  particular  event is likely to
effect a  material  change  in the  value of such  security.  Foreign  currency,
including forward  contracts,  will be valued at the closing price in the London
foreign  exchange  market  that day as provided  by a reliable  bank,  dealer or
pricing service.  The values of securities  denominated in foreign currency will
be converted to U.S. dollars at the closing price in the London foreign exchange
market that day as provided by a reliable bank, dealer or pricing service.

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

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

   
AccountLink.  When shares are purchased through AccountLink,  each purchase must
be at least  $25.00.  Shares will be purchased  on the regular  business day the
Distributor  is  instructed  to initiate the  Automated  Clearing  House ("ACH")
transfer to buy shares.  Dividends  will begin to accrue on shares  purchased by
the proceeds of ACH  transfers on the  business  day the Fund  receives  Federal
funds for the purchase  through the ACH system  before the close of The New York
Stock Exchange. The Exchange normally closes at 4:00 P.M., but may close earlier
on certain days. If Federal funds
    

                                     -32-

<PAGE>



   
are received  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 Rights of Accumulation and Letters
of Intent because of the economies of sales efforts and in expenses  realized by
the  Distributor,  dealers and brokers  making  such sales.  No sales  charge is
imposed  in  certain  circumstances  described  in the  Prospectus  because  the
Distributor,  dealer or broker  incurs little or no selling  expenses.  The term
"immediate  family" refers to one's spouse,  children,  grandchildren,  parents,
grandparents,   aunts,  uncles,  nieces,  nephews,  parents-in-law,   sons-  and
daughters-in-law,   siblings,  a  sibling's  spouse  and  a  spouse's  siblings.
Relations  by virtue of a  remarriage  (step-children,  step-parents,  etc.) are
included.

and the following "Money Market Funds":

Centennial America Fund, L.P.
Centennial California Tax Exempt Trust
Centennial  Government Trust
Centennial Money Market Trust
Centennial  New  York  Tax  Exempt  Trust
Centennial  Tax  Exempt  Trust
Oppenheimer Cash Reserves
Oppenheimer Money Market Fund, Inc.

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

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

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

    For  purchases  of  shares  of the  Fund  and  other  Oppenheimer  funds  by
OppenheimerFunds  prototype 401(k) plans under a Letter of Intent,  the Transfer
Agent will not hold shares in escrow.  If the intended purchase amount under the
Letter  entered  into  by an  OppenheimerFunds  prototype  401(k)  plan  is  not
purchased by the plan by the end of the Letter of Intent  period,  there will be
no adjustment of commissions paid to the broker-dealer or financial  institution
of record for accounts held in the name of that plan.

    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
purchases. If total eligible purchases during the Letter of Intent period exceed
the intended

                                     -34-

<PAGE>



purchase  amount  and exceed  the  amount  needed to qualify  for the next sales
charge rate reduction set forth in the applicable prospectus,  the sales charges
paid will be adjusted to the lower rate, but only if and when the dealer returns
to the  Distributor  the excess of the amount of commissions  allowed or paid to
the dealer  over the amount of  commissions  that apply to the actual  amount of
purchases.  The excess  commissions  returned to the Distributor will be used to
purchase additional shares for the investor's account at the net asset value per
share in effect on the date of such purchase,  promptly after the  Distributor's
receipt thereof.

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

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

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

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

      4. By  signing  the  Letter,  the  investor  irrevocably  constitutes  and
appoints the Transfer Agent as  attorney-in-fact to surrender for redemption any
or all escrowed shares.

      5. The shares  eligible for  purchase  under the Letter (or the holding of
which may be counted toward  completion of a Letter)  include (a) Class A shares
sold with a front-end  sales charge or subject to a Class A contingent  deferred
sales charge, (b) Class B shares acquired subject to a contingent deferred sales
charge, and (c) Class A shares or Class B shares acquired in exchange for either
(i) 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 (ii) Class B
shares of one of the other  Oppenheimer  funds that were  acquired  subject to a
contingent deferred sales charge.

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

                                     -35-

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

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

Retirement Plans. In describing certain types of employee benefit plans that may
purchase Class A shares without being subject to the Class A contingent deferred
sales charge,  the term "employee  benefit plan" means any plan or  arrangement,
whether or not "qualified" under the Internal Revenue Code,  including,  medical
savings  accounts,  payroll  deduction  plans or similar  plans in which Class A
shares  are  purchased  by a  fiduciary  or  other  person  for the  account  of
participants who are employees of a single employer or of affiliated  employers,
if the Fund account is  registered  in the name of the fiduciary or other person
for the benefit of participants in the plan.

   
      The term "group  retirement  plan" means any  qualified  or  non-qualified
retirement plan  (including 457 plans,  SEPs,  SARSEPs,  403(b) plans other than
public school 403(b) plans,  and SIMPLE plans) for employees of a corporation or
a 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 or  association  has made special  arrangements  with the
Distributor and all members of the group or association  participating in or who
are eligible to participate  in the plan(s)  purchase Class A shares of the Fund
through a single  investment  dealer,  broker,  or other  financial  institution
designated  by the  group.  "Group  retirement  plan"  also  includes  qualified
retirement plans and  non-qualified  deferred  compensation  plans and IRAs that
purchase Class A shares of the Fund through a single investment dealer,  broker,
or  other  financial  institution,   if  that  broker-dealer  has  made  special
arrangements  with the  Distributor  enabling  those plans to  purchase  Class A
shares of the Fund at net asset value but subject to a contingent deferred sales
charge.

      In addition to the discussion in the Prospectus relating to the ability of
Retirement  Plans to  purchase  Class A shares  at net  asset  value in  certain
circumstances,  there is no initial  sales charge on purchases of Class A shares
of any  one or  more  of the  Oppenheimer  funds  by a  Retirement  Plan  in the
following cases:

      (i) the record  keeping for the  Retirement  Plan is  performed on a daily
valuation basis by Merrill Lynch Pierce Fenner & Smith,  Inc.  ("Merrill Lynch")
and, on the date the plan sponsor signs the Merrill Lynch record keeping service
agreement,  the  Retirement  Plan has $3 million or more in assets  invested  in
mutual funds other than those advised or managed by Merrill Lynch Asset
    

                                     -36-

<PAGE>



   
Management,  L.P.  ("MLAM")  that  are  made  available  pursuant  to a  Service
Agreement  between Merrill Lynch and the mutual fund's principal  underwriter or
distributor  and  in  funds  advised  or  managed  by  MLAM  (collectively,  the
"Applicable Investments"); or

      (ii) the record  keeping for the  Retirement  Plan is performed on a daily
valuation  basis by an  independent  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 Merrill  Lynch record  keeping  service
agreement,  the Plan must have $3 million or more is  assets,  excluding  assets
held in money market funds, invested in Applicable Investments; or

      (iii) the Plan has 500 or more  eligible  employees,  as determined by the
Merrill  Lynch plan  conversion  manager on the date the plan sponsor  signs the
Merrill Lynch record keeping service agreement.

      If a Retirement  Plan's records are maintained on a daily  valuation basis
by Merrill  Lynch or an  independent  record keeper under a contract or alliance
arrangement  with Merrill  Lynch,  and if on the date the plan sponsor signs the
Merrill Lynch record keeping service  agreement the Retirement Plan has less the
$3 million in assets,  excluding  money  market  funds,  invested in  Applicable
Investments, then the Retirement Plan may purchase only Class B shares of one or
more of the Oppenheimer funds. Otherwise,  the Retirement Plan will be permitted
to purchase Class A shares of one or more of the Oppenheimer funds. Any of those
Retirement  Plans that currently  invest in Class B shares of the Fund will have
their  Class B shares  converted  to Class A shares of the Fund once the  Plan's
Applicable Investments have reached $5 million.

      Any  redemptions  of  shares of the Fund held by  Retirement  Plans  whose
records  are  maintained  on a daily  valuation  basis  by  Merrill  Lynch or an
independent record keeper under a contract with Merrill Lynch that are currently
invested  in Class B shares  of the Fund  shall  not be  subject  to the Class B
contingent deferred sales charge.
    

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.

How to Sell Shares

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

o  Involuntary  Redemptions.  The Board of Directors  has the right to cause the
involuntary  redemption  of the shares held in any Fund account if the aggregate
net asset value of those  shares is less than $500 or such lesser  amount as the
Board may fix. The Board of Directors will not cause the involuntary  redemption
of shares in an  account  if the  aggregate  net asset  value of the  shares has
fallen  below the  stated  minimum  solely  as a result of market  fluctuations.
Should the Board elect to exercise  this right,  it may also fix, in  accordance
with the  Investment  Company  Act,  and the  provisions  of Maryland  law,  the
requirements  for any notice to be given to the  shareholders  in question  (not
less than 30 days),  or the Board may set  requirements  for the  Shareholder to
increase

                                     -37-

<PAGE>



the investment,  and set other terms and conditions so that the shares would not
be involuntarily redeemed.

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

Reinvestment  Privilege.  Within six months of a redemption,  a shareholder  may
reinvest all or part of the  redemption  proceeds of (i) Class A shares that you
purchased  subject to an initial or contingent  deferred  sales charge,  or (ii)
Class B shares on which you paid a  contingent  deferred  sales  charge when you
redeemed them. It does not apply to Class C shares. 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
below,  at the net asset value next computed  after the Transfer  Agent receives
the  reinvestment  order.  The  shareholder  must ask the  Distributor  for that
privilege at the time of  reinvestment.  Any capital gain that was realized when
the shares were redeemed is taxable, and reinvestment will not alter any capital
gains  tax  payable  on that  gain.  If  there  has been a  capital  loss on the
redemption, some or all of the loss may not be tax deductible,  depending on the
timing and amount of the  reinvestment.  Under the Internal Revenue Code, if the
redemption  proceeds  of Fund  shares  on  which a sales  charge  was  paid  are
reinvested in shares of the Fund or another of the  Oppenheimer  funds within 90
days of payment of the sales charge,  the  shareholder's  basis in the shares of
the Fund that were redeemed may not include the amount of the sales charge paid.
That would reduce the loss or increase the gain  recognized from the redemption.
However, in that case the sales charge would be added to the basis of the shares
acquired by the  reinvestment  of the redemption  proceeds.  The Fund may amend,
suspend or cease offering this  reinvestment  privilege at any time as to shares
redeemed after the date of such amendment, suspension or cessation.

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

   
Distributions   From  Retirement   Plans.   Requests  for   distributions   from
OppenheimerFunds-sponsored   IRAs,  403(b)(7)  custodial  plans,  401(k)  plans,
pension   or   profit-sharing   plans   should   be   addressed   to   "Trustee,
OppenheimerFunds Retirement Plans," c/o the
    

                                     -38-

<PAGE>



Transfer  Agent at its address  listed in "How To Sell Shares" in the Prospectus
or on the back cover of this  Statement of Additional  Information.  The request
must:  (i)  state the  reason  for the  distribution;  (ii)  state  the  owner's
awareness of tax penalties if the  distribution is premature;  and (iii) conform
to the  requirements of the plan and the Fund's other  redemption  requirements.
Participants,  other than self-employed  persons,  maintaining a plan account in
their own name, in OppenheimerFunds-sponsored  prototype pension, profit-sharing
or  401(k)  plans may not  directly  redeem or  exchange  shares  held for their
account  under those  plans.  The employer or plan  administrator  must sign the
request.  Distributions  from  pension and profit  sharing  plans are subject to
special  requirements  under the  Internal  Revenue  Code and certain  documents
(available  from the Transfer Agent) must be completed  before the  distribution
may be made.  Distributions  from  retirement  plans are subject to  withholding
requirements  under the Internal Revenue Code, and IRS Form W-4P (available from
the  Transfer   Agent)  must  be  submitted  to  the  Transfer  Agent  with  the
distribution request, or the distribution may be delayed. Unless the shareholder
has provided the Transfer Agent with a certified taxpayer identification number,
the Internal  Revenue Code requires  that tax be withheld from any  distribution
even if the shareholder elects not to have tax withheld.  The Fund, the Manager,
the Distributor,  the Trustee and the Transfer Agent assume no responsibility to
determine whether a distribution satisfies the conditions of applicable tax laws
and will not be responsible for any tax penalties  assessed in connection with a
distribution.

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

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

                                     -39-

<PAGE>



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 Class B or the Class C contingent
deferred sales charge is waived as described in the Prospectus under "Waivers of
Class B Sales or Class C Sales Charges").

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

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

      o Automatic Withdrawal Plans. Fund shares will be redeemed as necessary to
meet  withdrawal  payments.  Shares  acquired  without  a sales  charge  will be
redeemed first and 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
withdrawal  plans  should  not be  considered  as a  yield  or  income  on  your
investment.  It may not be desirable to purchase additional Class A shares while
making  automatic  withdrawals  because  of the  sales  charges  that  apply  to
purchases  when made.  Accordingly,  a shareholder  normally may not maintain an
Automatic Withdrawal Plan while simultaneously making regular purchases of Class
A shares.

      The Transfer Agent will  administer the  investor's  Automatic  Withdrawal
Plan (the "Plan") as agent for the investor (the  "Planholder") who executed the
Plan authorization and application submitted to the Transfer Agent. The Transfer
Agent and the Fund shall incur no  liability  to the  Planholder  for any action
taken or omitted by the  Transfer  Agent in good faith to  administer  the Plan.
Certificates  will not be issued for shares of the Fund  purchased  for and held
under the Plan,  but the  Transfer  Agent  will  credit  all such  shares to the
account of the  Planholder  on the records of the Fund.  Any share  certificates
held by a Planholder  may be  surrendered  unendorsed to the Transfer Agent with
the Plan  application so that the shares  represented by the  certificate may be
held under the Plan.

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

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

      The amount and the  interval of  disbursement  payments and the address to
which  checks  are to be mailed or  AccountLink  payments  are to be sent may be
changed at any time by the Planholder

                                     -40-

<PAGE>



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

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

      To use Class A shares held under the Plan as  collateral  for a debt,  the
Planholder  may  request  issuance  of a  portion  of  the  Class  A  shares  in
certificated  form.  Share  certificates  are not  issued for Class B or Class C
shares.  Upon written  request  from the  Planholder,  the  Transfer  Agent will
determine  the  number of Class A shares for which a  certificate  may be issued
without  causing  the  withdrawal  checks  to  stop  because  of  exhaustion  of
uncertificated  shares  needed  to  continue  payments.   However,  should  such
uncertificated shares become exhausted,  Plan withdrawals will terminate. If the
Transfer Agent ceases to act as transfer agent for the Fund, the Planholder will
be deemed to have  appointed  any  successor  transfer  agent to act as agent in
administering the Plan.

How To Exchange Shares

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

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

      Class A shares of  Oppenheimer  funds may be  exchanged at net asset value
for shares of any money market fund.  Shares of any money market fund  purchased
without a sales charge may be exchanged for shares of Oppenheimer  funds offered
with a sales charge upon payment of the sales
    

                                     -41-

charge (or, if applicable,  may be used to purchase shares of Oppenheimer  funds
subject to a contingent deferred sales charge).  However,  shares of Oppenheimer
Money Market Fund,  Inc.  purchased  with the  redemption  proceeds of shares of
other mutual funds (other than funds managed by the Manager or its subsidiaries)
redeemed within the 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,  whichever is applicable.  To qualify for that
privilege,  the investor or the investor's dealer must notify the Distributor of
eligibility  for this  privilege  at the time the  shares of  Oppenheimer  Money
Market  Fund,  Inc.  are  purchased,  and, if  requested,  must supply  proof of
entitlement to this  privilege.  Shares of this Fund acquired by reinvestment of
dividends  or  distribution  from any  other of the  Oppenheimer  funds  (except
Oppenheimer  Cash  Reserves)  or  from  any  unit  investment  trust  for  which
reinvestment  arrangements  have been made with the Distributor may be exchanged
at net asset value for shares of any of the Oppenheimer funds.

      No contingent  deferred  sales charge is imposed on exchanges of shares of
any class purchased subject to a contingent deferred sales charge. However, when
Class A shares acquired by exchange of Class A shares of other Oppenheimer funds
purchased  subject to a Class A  contingent  deferred  sales charge are redeemed
within 12 months of the end of the calendar month of the initial purchase of the
exchanged Class A shares (18 months for shares  purchased prior to May 1, 1997),
the Class A contingent  deferred sales charge is imposed on the redeemed  shares
(see "Class A Contingent Deferred Sales Charge" in the Prospectus).  The Class B
contingent  deferred  sales  charge is  imposed  on Class B shares  acquired  by
exchange if they are  redeemed  within six years of the initial  purchase of the
exchanged  Class B  shares.  The Class C  contingent  deferred  sales  charge is
imposed on Class C shares  acquired by exchange if they are  redeemed  within 12
months of the initial purchase of the exchanged Class C shares.
    

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

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

      When  exchanging  shares by telephone,  a shareholder  must either have an
existing  account in, or obtain and acknowledge  receipt of a prospectus of, the
fund to which the  exchange is to be made.  For full or partial  exchanges of an
account made by telephone,  any special  account  features such as Asset Builder
Plans, Automatic Withdrawal Plans,  Checkwriting,  if available,  and retirement
plan contributions 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.


                                     -42-

<PAGE>



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

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

Dividends, Capital Gains and Taxes

Tax Status of the Fund's Dividends and Distributions.  The Federal tax treatment
of the Fund's  dividends  and capital  gains  distributions  is explained in the
Prospectus  under the caption  "Dividends,  Capital  Gains and  Taxes."  Special
provisions  of the Internal  Revenue Code govern the  eligibility  of the Fund's
dividends  for the  dividends-received  deduction  for  corporate  shareholders.
Long-term  capital gains  distributions  are not eligible for the deduction.  In
addition,  the amount of  dividends  paid by the Fund which may  qualify for the
deduction is limited to the aggregate  amount of qualifying  dividends  that the
Fund derives from its portfolio investments that the Fund has held for a minimum
period,  usually 46 days. A corporate  shareholder  will not be eligible for the
deduction  on  dividends  paid on Fund shares  held for 45 days or less.  To the
extent the Fund's  dividends are derived from gross income from option premiums,
interest  income or  short-term  gains from the sale of  securities or dividends
from foreign corporations, those dividends will not qualify for the deduction.

      Under the Internal  Revenue Code, by December 31 each year,  the Fund must
distribute  98% of its taxable  investment  income earned from January 1 through
December  31 of that year and 98% of its  capital  gains  realized in the period
from  November 1 of the prior year through  October 31 of the current  year,  or
else the Fund must pay an excise tax on the amounts not distributed. While it is
presently  anticipated that the Fund will meet those requirements,  the Board of
Directors and the Manager might  determine in a particular year that it would be
in the best interest of shareholders for the Fund not to make such 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.

   
      If the Fund  qualifies  as a  "regulated  investment  company"  under  the
Internal Revenue Code, it will not be liable for Federal income taxes on amounts
paid by it as dividends  and  distributions.  The Fund  qualified as a regulated
investment  company in its last  fiscal  year,  and intends to qualify in future
years, but reserves the right not to qualify. The Internal Revenue Code contains
a number of complex  tests  relating to  qualification  which the Fund might not
meet in any particular year. If it did not so qualify, the Fund would be treated
for tax purposes as an ordinary  corporation  and receive no tax  deduction  for
payments made to shareholders.
    

Dividends,   distributions  and  proceeds  of  the  redemption  of  Fund  shares
represented by checks

                                     -43-

<PAGE>



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

      If prior  distributions must be  re-characterized at the end of the fiscal
year as a result of the effect of the Fund's investment  policies,  shareholders
may have a non-taxable return of capital, which will be identified in notices of
shareholders.  There is no fixed  dividend rate and there can be no assurance as
to the payment of any dividends or the realization of any capital gains.

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

Additional Information About the Fund

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

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

Independent Auditors' Report

================================================================================
The Board of Directors  and  Shareholders  of  Oppenheimer  Main Street Income &
Growth Fund:


We have audited the accompanying statement of assets and liabilities,  including
the statement of investments, of Oppenheimer Main Street Income & Growth Fund as
of August 31, 1997, the related statement of operations for the year then ended,
the  statements  of changes in net assets for the year then  ended,  for the two
months ended August 31, 1996 and the year ended June 30, 1996, and the financial
highlights  for the period  July 1, 1992 to August  31,  1997.  These  financial
statements  and  financial  highlights  are  the  responsibility  of the  Fund's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements and financial highlights based on our audits.
           We  conducted  our  audits  in  accordance  with  generally  accepted
auditing  standards.  Those standards require that we plan and perform the audit
to obtain  reasonable  assurance  about  whether the  financial  statements  and
financial  highlights  are free of  material  misstatement.  An  audit  includes
examining,  on a test basis,  evidence supporting the amounts and disclosures in
the financial  statements.  Our procedures  included  confirmation of securities
owned at August 31, 1997 by correspondence with the custodian and brokers; where
replies were not received from brokers, we performed other auditing  procedures.
An audit also includes assessing the accounting  principles used and significant
estimates  made by  management,  as well as  evaluating  the  overall  financial
statement  presentation.  We believe that our audits provide a reasonable  basis
for our opinion.
           In our opinion,  such financial  statements and financial  highlights
present fairly, in all material respects,  the financial position of Oppenheimer
Main  Street  Income & Growth  Fund at  August  31,  1997,  the  results  of its
operations,  the changes in its net assets, and the financial highlights for the
respective  stated  periods,  in conformity with generally  accepted  accounting
principles.

commissions  when  expressed  as cents per share but higher when  expressed as a
percentage  of  transactions  because  of the  lower  per-share  prices  of many
non-U.S. securities. See accompanying Notes to Financial Statements.

Notes to Financial Statements

================================================================================
1. Significant Accounting Policies
Oppenheimer Main Street Income & Growth Fund (the Fund) is a separate series of
Oppenheimer Main Street Funds, Inc., an open-end management investment company
registered  under the  Investment  Company Act of 1940,  as amended.  The Fund's
investment objective is to seek high total return (which includes current income
and  capital  appreciation  in the value of its  shares)  from  equity  and debt
securities.  The  Fund's  investment  adviser  is  OppenheimerFunds,  Inc.  (the
Manager).  The Fund offers Class A, Class B, Class C and Class Y shares. 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.  Classes  A, B and C have  separate
distribution  and/or  service  plans.  No such plan has been adopted for Class Y
shares.  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.

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 Directors. 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  Directors  to
determine  fair  value  in good  faith.  Short-term  "money  market  type"  debt
securities having a remaining maturity of 60 days or less are valued at cost (or
last  determined  market  value)  adjusted for  amortization  to maturity of any
premium or discount.  Forward  foreign  currency  exchange  contracts are valued
based on the closing prices of the forward currency contract rates in the London
foreign  exchange  markets on a daily basis as  provided  by a reliable  bank or
dealer.  Options  are valued  based  upon the last sale  price on the  principal
exchange  on which the option is traded or, in the  absence of any  transactions
that day, the value is based upon the last sale price on the prior  trading date
if it is within the spread between the closing bid and asked prices. If the last
sale price is outside the spread, the closing bid is used.

================================================================================
Foreign Currency Translation. The accounting records of the Fund are maintained
in U.S. dollars. Prices of securities denominated in foreign currencies are
translated into U.S. dollars at the closing rates of exchange. Amounts related
to the purchase and sale of foreign securities and investment income are
translated at the rates of exchange prevailing on the respective dates of such
transactions.
              The  effect of  changes  in  foreign  currency  exchange  rates on
investments is separately  identified from the fluctuations arising from changes
in market values of securities held and reported with all other foreign currency
gains and losses in the Fund's Statement of Operations.
- --------------------------------------------------------------------------------
Repurchase Agreements. The Fund requires the custodian to take possession, to
have legally segregated in the Federal Reserve Book Entry System or to have
segregated within the custodian's vault, all securities held as collateral for
repurchase agreements. The market value of the underlying securities is
required to be at least 102% of the resale price at the time of purchase. If
the seller of the agreement defaults and the value of the collateral declines,
or if the seller enters an insolvency  proceeding,  realization  of the value of
the collateral by the Fund may be delayed or limited.
- --------------------------------------------------------------------------------
Allocation of Income,  Expenses, and Gains and Losses.  Income,  expenses (other
than those  attributable to a specific class) and gains and losses are allocated
daily to each class of shares based upon the relative  proportion  of net assets
represented  by  such  class.  Operating  expenses  directly  attributable  to a
specific class are charged against the operations of that class.
- --------------------------------------------------------------------------------
Federal Taxes. The Fund intends to continue to comply with provisions of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income, including any net realized gain on
investments not offset by loss carryovers, to shareholders. Therefore, no
federal income or excise tax provision is required.
- --------------------------------------------------------------------------------
Distributions to Shareholders. Dividends and distributions to shareholders are
recorded on the ex-dividend date.

Notes to Financial Statements (Continued)

================================================================================
1. Significant Accounting Policies (continued)
Classification  of Distributions to Shareholders.  Net investment  income (loss)
and net realized gain (loss) may differ for financial statement and tax purposes
primarily  because of the recognition of certain foreign currency gains (losses)
as ordinary income (loss) for tax purposes.  The character of the  distributions
made during the year from net investment income or net realized gains may differ
from its ultimate characterization for federal income tax purposes. Also, due to
timing  of  dividend  distributions,  the  fiscal  year  in  which  amounts  are
distributed may differ from the fiscal year in which the income or realized gain
was recorded by the Fund.
              During the period  ended August 31,  1997,  the Fund  adjusted the
classification  of  distributions  to  shareholders  to reflect the  differences
between financial  statement amounts and distributions  determined in accordance
with income tax  regulations.  Accordingly,  during the period  ended August 31,
1997,  amounts have been reclassified to reflect a decrease in undistributed net
investment  income of $94,463,  an increase in accumulated  net realized gain on
investments of $120,688, and a decrease in paid-in capital of $26,225.
- --------------------------------------------------------------------------------
Other. Investment transactions are accounted for on the date the investments are
purchased  or  sold  (trade  date)  and  dividend  income  is  recorded  on  the
ex-dividend date. Discount on securities purchased is amortized over the life of
the respective  securities,  in accordance with federal income tax requirements.
Realized  gains and  losses  on  investments  and  unrealized  appreciation  and
depreciation are determined on an identified cost basis, which is the same basis
used for federal income tax purposes.
              The  preparation  of  financial   statements  in  conformity  with
generally accepted  accounting  principles requires management to make estimates
and assumptions  that affect the reported  amounts of assets and liabilities and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements and the reported  amounts of income and expenses during the reporting
period. Actual results could differ from those estimates.

3. Unrealized Gains and Losses on Investments
At August 31, 1997, net unrealized appreciation on investments of
$1,823,894,321 was composed of gross appreciation of $1,866,266,967, and gross
depreciation of $42,372,646.
================================================================================
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 0.65% of the first
$200 million of net assets of the Fund, 0.60% of the next $150 million, 0.55% of
the next $150 million and 0.45% of net assets in excess of $500 million.
              For the year ended August 31,  1997,  commissions  (sales  charges
paid by  investors)  on sales of Class A shares  totaled  $25,549,129,  of which
$6,761,014  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   $38,556,921  and  $2,094,866,
respectively,  of which  $1,206,092  and $48,602,  respectively,  was paid to an
affiliated  broker/dealer.  During the year ended August 31, 1997, OFDI received
contingent  deferred sales charges of $5,230,649 and $227,950 upon redemption of
Class B and Class C 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
August  31,  1997,  OFDI  paid  $428,606  to  an  affiliated   broker/dealer  as
reimbursement for Class A personal service and maintenance expenses.


28   Oppenheimer Main Street Income & Growth Fund
<PAGE>


================================================================================
The Fund has  adopted  Distribution  and  Service  Plans for Class B and Class C
shares to reimburse OFDI for its services and costs in distributing  Class B and
Class C shares and servicing  accounts.  Under the Plans,  the Fund pays OFDI an
annual asset-based sales charge of 0.75% per year on Class B and Class C shares,
as reimbursement  for sales  commissions paid from its own resources at the time
of sale and  associated  financing  costs.  OFDI also  receives a service fee of
0.25%  per year as  reimbursement  for costs  incurred  in  connection  with the
personal  service  and  maintenance  of  accounts  that hold shares of the Fund,
including  amounts  paid  to  brokers,   dealers,   banks  and  other  financial
institutions. Both fees are computed on the average annual net assets of Class B
and Class C shares,  determined  as of the close of each regular  business  day.
During  the year  ended  August  31,  1997,  OFDI  paid  $74,879  and  $135,581,
respectively,  to an affiliated  broker/dealer as reimbursement  for Class B and
Class C personal service and maintenance  expenses and retained  $22,635,581 and
$2,838,009,  respectively,  as  reimbursement  for  Class  B and  Class  C sales
commissions and service fee advances, as well as financing costs. If either Plan
is terminated by the Fund, the Board of Directors may allow the Fund to continue
payments of the asset-based sales charge to OFDI for distributing  shares before
the Plan was  terminated.  At August 31, 1997,  OFDI had  incurred  unreimbursed
expenses of $92,083,482 for Class B and $7,962,219 for Class C.
================================================================================
5. Futures Contracts
The Fund may buy and  sell  interest  rate  futures  contracts  in order to gain
exposure to or protect against changes in interest rates.  The Fund may also buy
or write put or call options on these futures contracts.
              The Fund  generally  sells  futures  contracts  to  hedge  against
increases in interest  rates and the resulting  negative  effect on the value of
fixed rate portfolio securities. The Fund may also purchase futures contracts to
gain exposure to changes in interest  rates as it may be more  efficient or cost
effective than actually buying fixed income securities.
              Upon  entering  into a futures  contract,  the Fund is required to
deposit  either  cash or  securities  (initial  margin) in an amount  equal to a
certain percentage of the contract value. Subsequent payments (variation margin)
are made or received by the Fund each day.  The  variation  margin  payments are
equal to the daily changes in the contract  value and are recorded as unrealized
gains and losses.  The Fund recognizes a realized gain or loss when the contract
is closed or expires.

Notes to Financial Statements (Continued)

================================================================================
5. Futures Contracts (continued)
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 August 31, 1997, the Fund had outstanding  futures contracts as
follows:

                            DESCRIPTION OF RATINGS

Ratings of Investments

Description of Moody's Investors Service, Inc. Bond Ratings

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

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

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

Baa: Bonds which are rated "Baa" are considered medium grade obligations,  i.e.,
they are neither  highly  protected nor poorly  secured.  Interest  payments and
principal  security  appear  adequate  for the present  but  certain  protective
elements may be lacking or may be  characteristically  unreliable over any great
length of time. Such bonds lack outstanding investment  characteristics and have
speculative characteristics as well.

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

B:  Bonds  which are rated  "B"  generally  lack  characteristics  of  desirable
investment.  Assurance of interest and principal  payments or of  maintenance of
other terms of the contract over any long period of time may be small.

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

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

C: Bonds which are rated "C" can be regarded as having  extremely poor prospects
of ever retaining any real investment standing.


                                     A-1

<PAGE>



Description of Standard & Poor's Bond Ratings

AAA: "AAA" is the highest rating  assigned to a debt obligation and indicates an
extremely strong capacity to pay principal and interest.

AA: Bonds rated "AA" also qualify as high quality debt obligations.  Capacity to
pay principal and interest is very strong, and in the majority of instances they
differ from "AAA" issues only in small degree.

A:  Bonds  rated  "A" have a strong  capacity  to pay  principal  and  interest,
although  they are somewhat  more  susceptible  to adverse  effects of change in
circumstances and economic conditions.

BBB:  Bonds  rated  "BBB" are  regarded  as having an  adequate  capacity to pay
principal and interest.  Whereas they normally  exhibit  protection  parameters,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened  capacity to pay  principal  and interest for bonds in this  category
than for bonds in the "A" category.

BB, B, CCC, CC: Bonds rated "BB," "B," "CCC" and "CC" are regarded,  on balance,
as  predominantly  speculative  with  respect to the  issuer's  capacity  to pay
interest and repay  principal in  accordance  with the terms of the  obligation.
"BB"  indicates the lowest degree of  speculation  and "CC" the highest  degree.
While such bonds will likely have some quality and  protective  characteristics,
these are outweighed by large  uncertainties  or major risk exposures to adverse
conditions.

C, D: Bonds on which no  interest  is being paid are rated "C." Bonds  rated "D"
are in default and payment of  interest  and/or  repayment  of  principal  is in
arrears.

Description of Fitch Investors Service, Inc. Ratings

AAA Bonds  considered to be investment  grade and of the highest credit quality.
The  obligor  has an  exceptionally  strong  ability to pay  interest  and repay
principal, which is unlikely to be affected by reasonably foreseeable events.

AA Bonds considered to be investment grade and of very high credit quality.  The
obligor's  ability to pay interest and repay principal is very strong,  although
not quite as strong as bonds rated "AAA."  Because  bonds rated in the "AAA" and
"AA"  categories  are  not  significantly   vulnerable  to  foreseeable   future
developments, short-term debt of these issuers is generally rated "F-1+."

A Bonds  considered  to be  investment  grade and of high  credit  quality.  The
obligor's  ability to pay  interest  and repay  principal  is  considered  to be
strong, but may be more vulnerable to adverse changes in economic conditions and
circumstances than bonds with higher ratings.

BBB Bonds considered to be investment grade and of satisfactory  credit quality.
The  obligor's  ability to pay interest and repay  principal is considered to be
adequate. Adverse changes in economic conditions and circumstances, however, are
more likely to have adverse impact on these bonds,  and therefore  impair timely
payment.  The  likelihood  that the  ratings  of these  bonds  will  fall  below
investment grade is higher than for bonds with higher ratings.

BB Bonds are considered  speculative.  The obligor's ability to pay interest and
repay principal may be affected over time by adverse economic changes.  However,
business and financial  alternatives  can be  identified  which could assist the
obligor in satisfying its debt service requirements.

                                     A-2

<PAGE>



B Bonds  are  considered  highly  speculative.  While  bonds in this  class  are
currently meeting debt service requirements, the probability of continued timely
payment of principal  and  interest  reflects the  obligor's  limited  margin of
safety and the need for reasonable  business and economic  activity  through the
life of the issue.

CCC Bonds have certain identifiable  characteristics which, if not remedied, may
lead to  default.  The  ability to meet  obligations  requires  an  advantageous
business and economic environment.

CC Bonds  are  minimally  protected.  Default  in  payment  of  interest  and/or
principal seems probable over time.

C Bonds are in imminent default in payment of interest or principal.

DDD, DD, and D Bonds are in default on interest and/or principal payments.  Such
bonds  are  extremely  speculative  and  should  be valued on the basis of their
ultimate recovery value in liquidation or  reorganization of the obligor.  "DDD"
represents the highest potential for recovery of these bonds, and "D" represents
the lowest potential for recovery.

Plus (+)  Minus  (-) Plus and  minus  signs  are used  with a rating  symbol  to
indicate the relative position of a credit within the rating category.  Plus and
minus signs, however, are not used in the "DDD," "DD," or "D" categories.

Description of Duff & Phelps' Ratings

Long-Term Debt and Preferred Stock

AAA Highest credit quality. The risk factors are negligible, being only slightly
more than for risk-free US Treasury debt.

AA+, AA & AA- High credit quality protection factors are strong.  Risk is modest
but may vary slightly from time to time because of economic conditions.

A+, A & A- Protection  factors are average but adequate.  However,  risk factors
are more variable and greater in periods of economic stress.

BBB+,  BBB  &  BBB-  Below  average  protection  factors  but  still  considered
sufficient  for  prudent  investment.  Considerable  variability  in risk during
economic cycles.

BB+, BB & BB- Below  investment  grade but deemed to meet  obligations when due.
Present or  prospective  financial  protection  factors  fluctuate  according to
industry  conditions or company  fortunes.  Overall  quality may move up or down
frequently within the category.

B+, B & B- Below  investment grade and possessing risk that obligations will not
be met when due. Financial protection factors will fluctuate widely according to
economic cycles,  industry conditions and/or company fortunes.  Potential exists
for  frequent  changes in the rating  within  this  category or into a higher of
lower rating grade.

CCC Well below investment grade securities.  Considerable  uncertainty exists as
to timely  payment of  principal  interest or  preferred  dividends.  Protection
factors  are  narrow  and  risk can be  substantial  with  unfavorable  economic
industry conditions, and/or with unfavorable company developments.

ABOUT THE FUND

Investment Objective and Policies

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

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

      o Municipal Bonds. The principal  classifications  of long-term  municipal
bonds in which the Fund may  invest  are  "general  obligation,"  "revenue"  and
"industrial  development"  bonds.  In  California,  municipal  bonds may also be
funded by property taxes in specially created  districts  (Mello-Roos or Special
Assessment  Bonds),  tax allocations based on increased property tax assessments
over a specified  period  (frequently for  redevelopment  projects) or specified
redevelopment area sales allocations.

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

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


                                     -2-

<PAGE>



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

      o Advance Refunding.  The refinancing of outstanding bonds by the issuance
of a new issue of bonds prior to the date on which the outstanding  bonds become
due or are callable is known as advance refunding.  Accordingly, for a period of
time,  both the issue being  refunded and the refunding  issue are  outstanding.
Bonds are "escrowed to maturity"  when the proceeds of the  refunding  bonds are
deposited in escrow for investment in federal securities in an amount sufficient
to pay,  when due, the  principal  of and interest on the issue being  refunded.
Bonds  are  considered  "pre-refunded"  when the  refunding  bond  proceeds  are
escrowed only until the call date of the refunded issue.

      o Mello-Roos  Bonds.  Bonds issued  pursuant to the California  Mello-Roos
Community Facilities Act ("Mello-Roos bonds") are used to finance infrastructure
projects (such as roads or sewage treatment plants) and are primarily secured by
real estate  taxes  levied on  property  located in the same  community  as that
project. Mello-Roos bond financing arose in response to limitations contained in
California's   statutory  limitations  on  real  property  taxes  (see  "Special
Investment Considerations -- California Municipal Securities" below), and do not
constitute  obligations of a municipality.  Timely payment of such bonds depends
on the  developer  or other  property  owners'  ability to pay their real estate
taxes,  which could be  adversely  affected by a declining  economy  and/or real
estate market.

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

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

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

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

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

                                     -3-

<PAGE>



     o Tax-Exempt Commercial Paper.  Tax-exempt commercial paper is a short-term
obligation with a stated maturity of 397 days or less. It is issued by state and
local governments or their agencies to finance seasonal working capital needs or
as short-term financing in anticipation of longer-term financing.

      o  Floating  Rate/Variable  Rate  Obligations.  The  Fund  may  invest  in
instruments  with floating or variable  interest  rates.  The interest rate on a
floating rate obligation is based on a stated  prevailing market rate, such as a
bank's prime rate,  the 91-day U.S.  Treasury  Bill rate,  the rate of return on
commercial paper or bank  certificates of deposit,  or some other standard.  The
rate on the  investment is adjusted  automatically  each time the market rate is
adjusted.  The interest  rate on a variable  rate  obligation is also based on a
stated  prevailing  market  rate but is  adjusted  automatically  at a specified
interval  of not  less  than one  year.  Some  variable  rate or  floating  rate
obligations  in which the Fund may invest have a demand  feature  entitling  the
holder to demand payment of an amount  approximately equal to the amortized cost
of the  instrument  or the  principal  amount  of the  instrument  plus  accrued
interest at any time, or at specified  intervals  not exceeding one year.  These
notes may or may not be backed by bank letters of credit.

      Variable  rate demand notes may include  master  demand  notes,  which are
obligations  that permit the Fund to invest  fluctuating  amounts in a note. The
amount may change daily without penalty, pursuant to direct arrangements between
the Fund, as the note purchaser,  and the issuer of the note. The interest rates
on  these  notes  fluctuate  from  time to  time.  The  issuer  of this  type of
obligation normally has a corresponding  right in its discretion,  after a given
period,  to prepay  the  outstanding  principal  amount of the  obligation  plus
accrued interest. The issuer must give a specified number of days' notice to the
holders of those  obligations.  Generally,  the changes in the interest  rate on
those 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 having the same maturity.

      Because these types of obligations are direct lending arrangements between
the note purchaser and issuer of the note, these instruments  generally will not
be traded.  Generally,  there is no established secondary market for these types
of  obligations,  although  they are  redeemable  from the issuer at face value.
Accordingly,  where  these  obligations  are not secured by letters of credit or
other credit support arrangements,  the Fund's right to redeem them is dependent
on the ability of the note issuer to pay principal and interest on demand. These
types of obligations  usually are not rated by credit rating agencies.  The Fund
may invest in obligations  that are not rated only if the Manager  determines at
the time of investment  that the  obligations  are of comparable  quality to the
other  obligations in which the Fund may invest.  The Manager,  on behalf of the
Fund,  will  monitor the  creditworthiness  of the issuers of the  floating  and
variable rate obligations in the Fund's portfolio on an ongoing basis.

      |X|  Inverse  Floaters  and Other  Derivative  Investments.  Some  inverse
floaters  have a feature known as an interest rate "cap" as part of the terms of
the investment. Investing in inverse floaters that have interest rate caps might
be part of a portfolio  strategy to try to maintain a high current yield for the
Fund when the Fund has invested in inverse  floaters that expose the Fund to the
risk of short-term  interest rate fluctuation.  Embedded caps hedge a portion of
the Fund's  exposure to rising  interest  rates.  When interest rates exceed the
pre-determined rate, the cap generates

                                     -4-

<PAGE>



additional  cash flows that offset the decline in interest  rates on the inverse
floater,  and the hedge is successful.  However, the Fund bears the risk that if
interest  rates do not rise  above the  pre-determined  rate,  the cap (which is
purchased for additional  cost) will not provide  additional cash flows and will
expire worthless.

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

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

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

                                     -5-

<PAGE>



including  certain  industrial  development  bonds,  qualified  mortgage  bonds,
qualified  Section  501(c)(3)  bonds,  qualified  student  loan bonds,  etc.) is
taxable under the revised rules.

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

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

      The  Federal  alternative  minimum  tax is  designed  to  ensure  that all
taxpayers pay some tax, even if their regular tax is zero.  This is accomplished
in part by including in taxable income certain tax preference  items in arriving
at  alternative  minimum  taxable  income.  The  Tax  Reform  Act,  which  makes
tax-exempt  interest from certain  private  activity bonds a tax preference item
for  purposes  of the  alternative  minimum  tax,  specifically  states that any
exempt-interest  dividend paid by a regulated investment company will be treated
as interest on a specific private activity bond to the extent of its

                                     -6-

<PAGE>



proportionate  share of the  interest on such bonds  received  by the  regulated
investment company. The Treasury is authorized to issue regulations implementing
this  provision.  The Fund may hold  Municipal  Securities the interest on which
(and thus a  proportionate  share of the  exempt-interest  dividends paid by the
Fund) will be subject to the  Federal  alternative  minimum  tax.  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 in situations  where the "adjusted  current
earnings" of the corporation exceeds its alternative minimum taxable income.

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

      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,  S&P,  Duff &
Phelps or Fitch  change as a result of  changes in such  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.

Special Investment  Considerations - California Municipal Securities.  As stated
in the Prospectus,  the values of the Fund's California Municipal Securities are
highly  sensitive to the fiscal  stability of California  and its  subdivisions,
agencies, instrumentalities or authorities, which issue the Municipal Securities
in which the Trust  concentrates  its  investments.  Certain  amendments  to the
California State constitution,  legislative  measures,  executive orders,  civil
actions and voter  initiatives in recent years that could  adversely  affect the
ability of  California  issuers  to pay  interest  and  principal  on  Municipal
Securities are described below. The following  constitutes only a brief summary,
and is based on information  drawn from the relevant  statutes and certain other
publicly  available  information.  The Fund has not independently  verified such
information.

      Changes  in  California  constitutional  and other  laws  during  the last
several years have caused  concerns  about the ability of  California  state and
municipal issuers to obtain sufficient revenue to pay their bond obligations. In
1978,  California  voters  approved an amendment to the California  Constitution
known  as   Proposition   13,  which  added  Article  XIIIA  to  the  California
Constitution.  Article  XIIIA  limits  ad  valorem  taxes on real  property  and
restricts  the  ability of taxing  entities  to increase  real  property  taxes.
However,  legislation  passed  subsequent  to  Proposition  13 provided  for the
redistribution  of  California's  General  Fund surplus to local  agencies,  the
reallocation  of revenues to local  agencies and the assumption of certain local
obligations  by the  state  so as to help  California  municipal  issuers  raise
revenue to pay their bond obligations. It is unknown whether additional

                                     -7-

<PAGE>



revenue redistribution legislation will be enacted in the future and whether, if
enacted,  such legislation will provide  sufficient  revenue for such California
issuers to pay their obligations.

      The state is also  subject to another  constitutional  amendment,  Article
XIIIB,  which may have an  adverse  impact  on  California  state and  municipal
issuers.  Article XIIIB restricts the state from spending certain appropriations
in excess of an appropriations limit imposed for each state and local government
entity.  If revenues  exceed such  appropriations  limit,  such revenues must be
returned  either  as  revisions  in the tax  rates  or fee  schedules.  In 1988,
California  voters  approved an  initiative  known as  Proposition  98, which in
addition to amending  Article  XIIIB,  amended  Article XVI to require a minimum
level of funding for public schools and community colleges.

      In 1986, California voters approved an initiative known as Proposition 62,
which,  among  other  things,  requires  that any tax for  general  governmental
purposes  imposed by a local  government be approved by a two-thirds vote of the
governmental  entity's  legislative body and by a majority of its electorate and
that any special tax imposed by a local  government  be approved by a two-thirds
vote of the  electorate.  In September 1995 the California  Supreme Court upheld
the constitutionality of Proposition 62, creating uncertainty as to the legality
of certain local taxes enacted by non-charter cities in California without voter
approval. It is not possible to predict the impact of the decision.

   
      In  November  1996,   California  voters  approved  Proposition  218.  The
initiative  applied the provisions of Proposition 62 to all entities,  including
charter cities.  It requires that all taxes for general purposes obtain a simple
majority  popular vote and that taxes for special  purposes  obtain a two-thirds
majority vote.  Prior to the  effectiveness  of Proposition  218, charter cities
could levy certain taxes such as transient  occupancy  taxes and utility  user's
taxes without a popular vote.  Proposition  218 will also limit the authority of
local  governments  to impose  property-related  assessments,  fees and charges,
requiring that such assessments be limited to the special benefit  conferred and
prohibiting their use for general  governmental  services.  Proposition 218 also
allows   voters   to  use   their   initiative   power  to   reduce   or  repeal
previously-authorized taxes, assessments, fees and charges.
    

      Because of the uncertain  impact of the  aforementioned  legislation,  the
possible  inconsistencies  in the  respective  terms  of the  statutes  and  the
impossibility of predicting the level of future appropriations and applicability
of related  statutes to such questions,  it is not currently  possible to assess
the impact of such  legislation  and  policies  on the long term  ability of the
State of California  and California  municipal  issuers to pay interest or repay
principal on their obligations.

   
      In addition,  certain  tax-exempt  securities in which the Fund may invest
may be obligations payable solely from the revenues of specific institutions, or
may be secured by  specific  properties,  which 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 laws, and  California  law limits the remedies of a creditor  secured by a
mortgage or deed of trust on real property.

      California's  economic recovery from the recent recession is continuing at
a strong pace,  and recent  economic  reports  indicate that  California is on a
stronger  economic  upturn  than the rest of the  country.  The rate of economic
growth in California in 1996, in terms of job gains, exceeded that of
    

                                     -8-

<PAGE>



   
the rest of the United States.  The State added nearly 350,000 jobs during 1996,
surpassing  its  pre-recession  employment  peak of 12.7 million  jobs.  Another
380,000 jobs are expected to be created in 1997. The  unemployment  rate,  while
still  higher  than the  national  average,  fell to the low 6 percent  range in
mid-1997, compared to over 10 percent during the recession. Many of the new jobs
were created in such industries 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, with particular large gains in the Silicon Valley region of Northern
California.

      On August 18, 1997,  the  Governor  signed the 1997-98  Budget Act,  which
provides for General Fund and Special Fund  expenditures of approximately  $67.2
billion and  projects a 97-98 fiscal year end reserve of $112  million.  For the
second year in a row, the State budget  contains a large increase in funding for
K-14 education,  reflecting strong revenues which have exceeded initial budgeted
amounts. The Budget Act reflects a $1.235 billion pension case judgment payment,
and returns funding of the State's  pension  contribution to the quarterly basis
existing prior to the deferral actions invalidated by the courts. Because of the
effect of the pension  payment,  most other State  programs  were  continued  at
1996-97 levels. Health and welfare costs are contained, continuing generally the
grant levels from prior years, as part of the initial  implementation of the new
CalWORKS  welfare reform program.  Unlike prior years,  this Budget Act does not
depend on uncertain federal budget actions. About $300 million in federal funds,
already  included in the federal FY 1997 and 1998  budgets,  are included in the
Budget Act to offset incarceration costs for illegal immigrants.  The Budget Act
contains  no tax  increases  and no tax  reductions.  The Renters Tax Credit was
suspended for another year, saving approximately $500 million.

      After enactment of the Budget Act, and prior to the end of the Legislative
Session,  the Legislature and the Governor reached certain agreements related to
State  expenditures  and taxes.  Legislation  signed by the Governor  includes a
variety of phased-in tax cuts, conformity with certain provisions of the federal
tax reform law passed  earlier this year, and reform of funding for county trial
courts, with the State to assume greater financial responsibility.

      Because  of the State of  California's  continuing  budget  problems,  the
state's General  Obligation  bonds were downgraded in July 1994 from Aa to A1 by
Moody's,  from  A+ to A by S&P and  from  AA to A by  Fitch.  All  three  rating
agencies  expressed  uncertainty in the state's ability to balance its budget by
1996.  However,  in 1996,  citing  California's  improving  economy  and  budget
situation,  both Fitch and Standard & Poor's  raised their ratings from A to A+.
Prior to California's  October 8 sale of $1 billion in General  Obligation Bonds
Fitch Investors Service raised California's  General Obligation Bond rating from
A+ to AA-,  Moody's  Investors  Service and Standard & Poors did not raise their
ratings, confirming those at A1 and A+, respectively.

      On  December  6, 1994,  Orange  County  (California)  became  the  largest
municipality  in the  United  States to file for  protection  under the  Federal
bankruptcy  laws. The filing stemmed from  approximately  $1.7 billion in losses
suffered  by the  County's  investment  pool  due to  investments  in high  risk
"derivative"  securities.  In  September  1995 the  state  legislature  approved
legislation permitting Orange County to use for bankruptcy recovery $820 million
over 20 years in sales taxes  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
    

                                     -9-

County emerged from  bankruptcy.  On January 7, 1997,  Orange County returned to
the municipal bond market with a $136 million bond issue maturing in 13 years at
an insured yield of 7.23 percent

      Los Angeles  County,  the nation's  largest county,  is also  experiencing
financial difficulty. In August 1995 the credit rating of the county's long-term
bonds was  downgraded  for the third time since 1992 as a result of, among other
things,  severe  operating  deficits  for the county's  health care  system.  In
addition,  the County was affected by an ongoing loss of revenue caused by state
property tax shift  initiatives  in 1993 through  1995. In June,  1997,  the Los
Angeles County Board of Supervisors  approved an approximate $12 billion 1997-98
budget  containing  measures to eliminate a $157 million  deficit.  The County's
budgetary difficulties have continued and their effect, as well as the effect of
the improving California economy, on the 1997-98 budget is still uncertain.
    

Other Investment Techniques and Strategies

      o  When-Issued  and  Delayed  Delivery  Transactions.  As  stated  in  the
Prospectus,  the Fund may invest in  securities on a  "when-issued"  or "delayed
delivery" basis.  Payment for and delivery of the securities generally shall not
exceed  120 days from the date the offer is  accepted.  The  purchase  price and
yield are fixed at the time the buyer  enters  into the  commitment.  During the
period between  purchase and  settlement,  no payment is made by the Fund to the
issuer and no interest  accrues to the Fund from the  investment.  However,  the
Fund  intends  to be as fully  invested  as  possible  and will  not  invest  in
when-issued  securities  if its  income or net asset  value  will be  materially
adversely  affected.  At the time the Fund makes the  commitment  to  purchase a
Municipal Security on a when-issued basis, it will record the transaction on its
books and reflect the value of the security in determining  its net asset value.
It will also segregate cash or other high quality  liquid  Municipal  Securities
equal  in  value  to  the  commitment  for  the  when-issued  securities.  While
when-issued securities may be sold prior to settlement date, the Fund intends to
acquire the securities upon settlement unless a prior sale appears desirable for
investment reasons.  There is a risk that the yield available in the market when
delivery occurs may be higher than the yield on the security acquired.

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

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

                                     -10-

<PAGE>



monitor the collateral's value.

      o  Illiquid  and  Restricted  Securities.  To  enable  the  Fund  to  sell
restricted  securities not registered under the Securities Act of 1933, the Fund
may  have  to  cause  those  securities  to  be  registered.   The  expenses  of
registration  of  restricted  securities  may be negotiated by the Fund with the
issuer  at the  time  such  securities  are  purchased  by  the  Fund,  if  such
registration  is required  before such  securities  may be sold  publicly.  When
registration  must be arranged  because the Fund wishes to sell the security,  a
considerable period may elapse between the time the decision is made to sell the
securities and the time the Fund would be permitted to sell them. The Fund would
bear the risks of any downward price  fluctuation  during that period.  The Fund
may also acquire,  through private  placements,  securities  having  contractual
restrictions on their resale, which might limit the Fund's ability to dispose of
such  securities  and might  lower the amount  realizable  upon the sale of such
securities.

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

      |X| Puts and Standby Commitments. When the Fund buys Municipal Securities,
it may obtain a standby commitment to repurchase the securities that entitles it
to achieve  same-day  settlement  from the  purchaser and to receive an exercise
price  equal to the  amortized  cost of the  underlying  security  plus  accrued
interest, if any, 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 may pay for a
standby  commitment or put either separately in cash or by paying a higher price
for the securities  acquired subject to the standby  commitment or put. The Fund
will enter into these  transactions  only with banks and dealers  which,  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 transferrable by the Fund, and
therefore  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 may enable the Fund to sell a security at
a pre-arranged price which 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 which could jeopardize the Fund's business  relationships with the
seller.  Any  consideration  paid by the Fund for the put or standby  commitment
(which  increases  the cost of the  security  and  reduces  the yield  otherwise
available from the security) 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

                                     -11-

<PAGE>



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.

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

   
      o Portfolio Turnover.  The Fund may purchase or sell Municipal  Securities
without  regard  to the  length  of time the  security  has been  held,  to take
advantage  of  short-term  differentials  in yields  consistent  with the Fund's
investment objective. While short-term trading increases portfolio turnover, the
execution  cost for such  securities is  substantially  less than for equivalent
dollar values of equity securities.
    

      o  Hedging.  The  Fund  may use  hedging  instruments  for the  purposes
described in the Prospectus. When hedging to attempt to protect against declines
in the  market  value of the  Fund's  portfolio,  to  permit  the Fund to retain
unrealized gains in the value of portfolio securities which have appreciated, or
to facilitate selling securities for investment reasons,  the Fund may: (1) sell
Interest  Rate Futures or  Municipal  Bond Index  Futures,  (2) buy puts on such
Futures or securities,  or (3) write covered calls on securities,  Interest Rate
Futures or  Municipal  Bond Index  Futures  (as  described  in the  Prospectus).
Covered calls may also be written on debt  securities to attempt to increase the
Fund's  income.  When  hedging to permit the Fund to establish a position in the
debt securities market as a temporary substitute for purchasing  individual debt
securities  (which the Fund will  normally  purchase,  and then  terminate  that
hedging position), the Fund may: (1) buy Interest Rate Futures or Municipal Bond
Index Futures, or (2) buy calls or write puts on such Futures or on securities.

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

     o Writing Covered Call Options.  As described in the  Prospectus,  the Fund
may write covered calls. When the Fund writes a call on a security,  it receives
a premium and agrees to sell the

                                     -12-

<PAGE>



underlying  investment  to a purchaser of a  corresponding  call during the call
period  (usually not more than nine months) at a fixed exercise price (which may
differ from the market price of the underlying  investment) regardless of market
price  changes  during the call  period.  The Fund has retained the risk of loss
should the price of the  underlying  security  decline  during the call  period,
which may be offset to some extent by the premium.

      To  terminate  its  obligation  on a call it has  written,  the  Fund  may
purchase a corresponding  call in a "closing purchase  transaction." A profit or
loss will be  realized,  depending  upon whether the net of the amount of option
transaction  costs and the premium  received on the call the Fund has written is
more or less  than the  price of the call  the Fund  subsequently  purchased.  A
profit may also be  realized if the call  lapses  unexercised,  because the Fund
retains the related  investments and the premium received.  Any such profits are
considered  short-term  capital gains for Federal income tax purposes,  and when
distributed by the Fund are taxable as ordinary  income.  An option position may
be closed out only on a market which provides  secondary  trading for options of
the same series,  and there is no assurance that a liquid  secondary market will
exist for any particular option. If the Fund could not effect a closing purchase
transaction  due to a lack of a  market,  it  would  have to hold  the  callable
securities until the call lapsed or was exercised.

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

      o Writing Put Options.  A put option on securities gives the purchaser the
right to sell, and the writer the  obligation to buy, the underlying  investment
at the exercise price during the option period. The Fund will not write puts if,
as a result,  more than 25% of the  Fund's net assets  would be  required  to be
segregated to cover such put options. Writing a put covered by segregated liquid
assets equal to the exercise  price of the put has the same  economic  effect to
the Fund as writing a covered call. The premium the Fund receives from writing a
put  option  represents  a  profit,  as  long  as the  price  of the  underlying
investment remains equal to or above the exercise price.  However,  the Fund has
also  assumed  the  obligation  during the option  period to buy the  underlying
investment  from the buyer of the put at the  exercise  price,  even  though the
value of the investment may fall below the exercise price less transaction costs
incurred.  If the put expires  unexercised,  the Fund (as the writer of the put)
realizes  a gain  in the  amount  of the  premium  less  the  transaction  costs
incurred.  If the put is  exercised,  the Fund must  fulfill its  obligation  to
purchase the  underlying  investment at the exercise  price,  which will usually
exceed the market value of the  investment at that time. In that case,  the Fund
may  incur  a  loss,  equal  to the  sum of the  sale  price  of the  underlying
investment and the premium  received minus the sum of the exercise price and any
transaction costs incurred.

      When writing put options on  securities,  to secure its  obligation to pay
for the underlying security,  the Fund will deposit in escrow liquid assets with
a  value  equal  to or  greater  than  the  exercise  price  of  the  underlying
securities.  The Fund  therefore  foregoes  the  opportunity  of  investing  the
segregated  assets  or  writing  calls  against  those  assets.  As  long as the
obligation  of the  Fund as the put  writer  continues,  it may be  assigned  an
exercise  notice  by the  broker-dealer  through  whom  such  option  was  sold,
requiring the Fund to take delivery of the underlying security against payment

                                     -13-

<PAGE>



of the exercise  price.  The Fund has no control over when it may be required to
purchase the underlying security, since it may be assigned an exercise notice at
any time prior to the  termination  of its  obligation as the writer of the put.
This  obligation  terminates upon expiration of the put, or such earlier time at
which the Fund effects a closing purchase transaction by purchasing a put of the
same series as that previously sold. Once the Fund has been assigned an exercise
notice, it is thereafter not allowed to effect a closing purchase transaction.

      o Purchasing Calls and Puts. When the Fund purchases a call (other than in
a closing  purchase  transaction),  it pays a premium and, except as to calls on
Municipal  Bond Index Futures,  has the right to buy the  underlying  investment
from a seller of a  corresponding  call on the same  investment  during the call
period at a fixed exercise  price.  In purchasing a call, the Fund benefits only
if the call is sold at a profit or if, during the call period,  the market price
of the  underlying  investment  is  above  the sum of the  call  price  plus the
transaction  costs and premium paid for the call, and the call is exercised.  If
the call is not exercised or sold  (whether or not at a profit),  it will become
worthless at its expiration  date and the Fund will lose its premium payment and
the right to purchase the underlying investment.  When the Fund purchases a call
or put on a municipal  bond index,  Municipal Bond Index Future or Interest Rate
Future, it pays a premium,  but settlement is in cash rather than by delivery of
the  underlying  investment to the Fund.  Gain or loss depends on changes in the
index in question  (and thus on price  movements in the debt  securities  market
generally) rather than on price movements in individual futures contracts.

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

      o  Interest  Rate  Futures.  The Fund may buy and sell  futures  contracts
relating to debt securities ("Interest Rate Futures") and municipal bond indices
("Municipal Bond Index Futures,"  discussed below). No price is paid or received
upon the purchase or sale of an Interest  Rate Future.  An Interest  Rate Future
obligates  the seller to deliver and the  purchaser  to take a specific  type of
debt  security  or cash to settle the futures  transaction,  or to enter into an
offsetting contract. Upon entering into a Futures transaction,  the Fund will be
required to deposit an initial  margin payment in cash or U.S.  Treasury  bills,
with the futures  commission  merchant (the "futures  broker").  Initial  margin
payments will be deposited with the Fund's Custodian in an account registered in
the futures broker's name;  however,  the futures broker can gain access to that
account  only under  certain  specified  conditions.  As the Future is marked to
market to reflect changes in its market value, (that is, its value on the Fund's
books is changed)  subsequent margin payments,  called variation margin, will be
paid to or by the futures broker on a daily basis.

     At any time prior to the  expiration  of the Future,  the Fund may elect to
close out its position

                                     -14-

<PAGE>



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.

      o Municipal Bond Index Futures.  A "municipal bond index" assigns relative
values to the municipal  bonds  included in that index,  and is used to serve as
the basis for trading long-term municipal bond futures contracts. Municipal Bond
Index  Futures are similar to Interest  Rate Futures  except that  settlement is
made in cash. No physical delivery is made of the underlying bonds in the index.
The  obligation  under such  contracts may also be satisfied by entering into an
offsetting  contract  to close  out the  futures  position.  Net gain or loss on
options on Municipal  Bond Index Futures  depends on the price  movements of the
securities  included  in the  index.  The  strategies  which  the  Fund  employs
regarding Municipal Bond Index Futures are similar to those described above with
regard to Interest Rate Futures.

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

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

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

                                     -15-

<PAGE>



purchasing a call.

   
      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
would  establish a formula price at which the Fund would have the absolute right
to repurchase that OTC option.  This 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
("in-the-money").  For any OTC option a Fund  writes,  it will treat as illiquid
(for  purposes  of  the  restriction  on  illiquid  securities,  stated  in  the
Prospectus)  the  mark-to-market  value  of any OTC  option  held by it,  unless
subject to a buy-back  agreement with the selling broker.  The SEC is evaluating
the general  issue of whether or not OTC options  should be considered as liquid
securities,  and the procedure  described above could be affected by the outcome
of that evaluation.
    

      An option  position  may be  closed  out only in a market  which  provides
secondary trading for options of the same series, and there is no assurance that
a liquid  secondary  market  will exist for any  particular  option.  The Fund's
option  activities may affect its 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 in a manner beyond the
Fund's  control.  The exercise by the Fund of puts on  securities or Futures may
cause the sale of  related  investments,  also  increasing  portfolio  turnover.
Although such exercise is within the Fund's  control,  holding a put might cause
the Fund to sell the underlying  investment for reasons which would not exist in
the absence of the put.  The Fund will pay a brokerage  commission  each time it
buys or sells a call, buys a put or an underlying  investment in connection with
the exercise of a put or call.  Such  commissions  may be higher,  on a relative
basis,  than  those  which  would  apply  to  direct  purchases  or sales of the
underlying  investments.  Premiums paid for options are small in relation to the
market value of such  investments and  consequently,  put and call options offer
large  amounts of  leverage.  The leverage  offered by trading in options  could
result in the Fund's net asset  value  being  more  sensitive  to changes in the
value of the underlying investment.

      o Regulatory Aspects of Hedging Instruments.  The Fund must operate within
certain  guidelines  and  restrictions  as to its long and  short  positions  in
Futures and options  thereon under a rule ("CFTC Rule") adopted by the Commodity
Futures  Trading  Commission  ("CFTC")  under the  Commodity  Exchange  Act (the
"CEA"),  which excludes the Fund from registration with the CFTC as a "commodity
pool  operator"  (as defined  under the CEA), if it complies with the CFTC Rule.
The Rule does not limit the percentage of the Fund's assets that may be used for
Futures margin and related  options  premiums for a bona fide hedging  position.
However, under the Rule the Fund must limit its aggregate initial futures margin
and  related  option  premiums  to not 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, as to its short  positions,  use
Futures and options  thereon  solely for bona fide hedging  purposes  within the
meaning and intent of the applicable provisions of the CEA.

   
      Transactions in options by the Fund are subject to limitations established
by each of the exchanges  governing  the maximum  number of options which may be
written or held by a single  investor or group of  investors  acting in concert,
regardless  of whether  the options  were  written or  purchased  on the same or
different exchanges or are held in one or more accounts or through one or
    

                                     -16-

<PAGE>



   
more  different  exchanges or through one or more brokers.  Thus,  the number of
options  which the Fund may write or hold may be affected by options  written or
held by other entities,  including other  investment  companies  having the same
adviser as the Fund or an affiliated  investment  adviser.  Position limits also
apply to Futures. An exchange may order the liquidation of positions found to be
in violation  of these limits and may impose  certain  other  sanctions.  Due to
requirements  under the  Investment  Company  Act,  when the Fund  purchases  an
Interest Rate Future or Municipal Bond Index Future, the Fund will maintain,  in
a segregated  account or accounts with its Custodian,  liquid assets of any type
including  equity  and debt  securities  of any grade in an amount  equal to the
market value of the investments  underlying such Future, less the margin deposit
applicable to it.
    

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

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

      If the Fund uses  hedging  instruments  to  establish  a  position  in the
securities  markets as a temporary  substitute  for the  purchase of  individual
securities (long hedging) by buying Futures and/or

                                     -17-

<PAGE>



calls on such Futures,  broadly-based indices, or on securities,  it is possible
that the  market  may  decline.  If the Fund  then  concludes  not to  invest in
securities  at that time  because of  concerns  as to  possible  further  market
decline or for other reasons,  it will realize a loss on the hedging instruments
that is not offset by a reduction in the price of the securities  purchased.  In
the future, the Fund may employ hedging  instruments and strategies that are not
presently contemplated but which may be developed, to the extent such investment
methods  are  consistent  with the  Fund's  investment  objective,  are  legally
permissible and are adequately disclosed.

Other Investment Restrictions

      The Fund's most significant  investment  restrictions are set forth in the
Prospectus.  There are  additional  investment  restrictions  that the Fund must
follow that are also fundamental  policies.  Fundamental policies and the Fund's
investment  objective  cannot be changed without the vote of a "majority" of the
Fund's outstanding  voting securities.  Under the Investment Company Act, such a
majority vote is defined as the vote of the holders of the lesser of: (1) 67% or
more of the  shares  present  or  represented  by  proxy  at such a  shareholder
meeting,  if the holders of more than 50% of the outstanding  shares are present
or represented by proxy, or (2) more than 50% of the outstanding shares.

      Under these additional restrictions:

      o The  Fund  cannot  invest  in  interests  in oil or gas  exploration  or
development  programs or in commodities;  however, the Fund may buy and sell any
of the  Hedging  Instruments  that it may use as  permitted  by any of its other
policies, whether or not such Hedging Instrument is considered to be a commodity
or commodity contract;

      o The Fund cannot  invest in real estate or in  interests  in real estate;
however,  the Fund may  purchase  securities  of issuers  holding real estate or
interests therein (including securities of real estate investment trusts);

      o The Fund cannot  purchase  securities on margin;  however,  the Fund may
make  margin  deposits  in  connection  with the use of Hedging  Instruments  as
permitted by any of its other policies;

          o The Fund cannot  invest in  companies  for the purpose of  acquiring
     control or management thereof;

      o The Fund cannot underwrite securities of other companies, except insofar
as it might be deemed to be an underwriter for purposes of the Securities Act of
1933 in the resale of any securities held in its own portfolio;

      o The  Fund  cannot  invest  or hold  securities  of any  issuer  if those
officers and directors of the  Corporation  or its adviser  owning  individually
more than 1/2 of 1% of the  securities of such issuer  together own more than 5%
of the securities of such issuer;

      o The Fund cannot invest in other open-end investment companies, or invest
more than 5% of its net assets  through  open  market  purchases  in  closed-end
investment companies, including small

                                     -18-

<PAGE>



business investment companies, nor make any such investments at commission rates
in excess of normal brokerage commissions; or

      o The Fund cannot  pledge,  mortgage or  otherwise  encumber,  transfer or
assign any of its assets to secure a debt;  collateral  arrangements for premium
and margin payments in connection with Hedging  Instruments are not deemed to be
a pledge of assets.

      o Diversification.  For purposes of  diversification  under the Investment
Company  Act, and the  restriction  on  investing  in any  "issuer"  above,  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 the subdivision and the security is backed only
by the assets and revenues of the subdivision,  such subdivision would be deemed
to be the sole issuer. Similarly, in the case of an industrial development bond,
if that bond is backed only by the assets and  revenues  of the  nongovernmental
user,  then such  nongovernmental  user  would be deemed to be the sole  issuer.
However,  if in  either  case  the  creating  government  or some  other  entity
guarantees the security,  such guarantee would be considered a separate security
and is to be treated as an issue of such government or other entity.

      In  applying  the  Fund's  policy  not  to  concentrate  its  investments,
described in the Prospectus, the Manager will consider a nongovernmental user of
facilities  financed by  industrial  development  bonds as being in a particular
industry,  despite the fact that such bonds are Municipal Securities as to which
there is no industry concentration limitation.  Although this application of the
restriction is not technically a fundamental  policy of the Fund, it will not be
changed  without  shareholder  approval.  Should  any such  change be made,  the
Prospectus and/or this Additional Statement will be supplemented to reflect such
change.

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

How the Fund is Managed

Organization  and History.  Oppenheimer  Main Street  California  Municipal Fund
(referred  to as the  "Fund") is one of two series of  Oppenheimer  Main  Street
Funds,  Inc. (the  "Corporation"),  a Maryland  corporation.  This  Statement of
Additional  Information  may be used with the  Fund's  Prospectus  only to offer
shares of the Fund.

      Each share of the Fund represents an interest in the Fund  proportionately
equal to the  interest  of each other  share of the same class and  entitle  the
holder to one vote per share (and a fractional  vote for a fractional  share) on
matters submitted to their vote at a shareholders' meeting.  Shareholders of the
Fund and of the  Corporation's  other series vote  together in the  aggregate on
certain matters at shareholders' meetings, such as the election of Directors and
ratification  of appointment of auditors of the  Corporation.  Shareholders of a
particular series or class vote

                                     -19-

<PAGE>



separately on proposals which affect that series or class, and shareholders of a
series or class which is not affected by that matter are not entitled to vote on
the proposal. For example, only shareholders of a series, such as the Fund, vote
exclusively on any material amendment to the investment  advisory agreement with
respect to the series.  Only shareholders of a class of a series vote on certain
amendments to the  Distribution  and/or Service Plans if the  amendments  affect
that class.

      The Directors  are  authorized to create new series and classes of shares.
The Directors may reclassify unissued shares of the Corporation or its series or
classes into  additional  series or classes of shares.  The  Directors  may also
divide or  combine  the  shares of a class  into a greater  or lesser  number of
shares  without  thereby  changing the  proportionate  beneficial  interest of a
shareholder  in the  Fund.  Shares  do not  have  cumulative  voting  rights  or
preemptive or subscription rights. Shares may be voted in person or by proxy.

      It is not contemplated  that regular annual  shareholder  meetings will be
held.  The Fund will hold  meetings  when  required  to do so by the  Investment
Company Act or other applicable law, or when a shareholder  meeting is called by
the  Directors  or  upon  proper  request  of the  shareholders.  A  meeting  of
shareholders will be called for a specific purpose (which may include removal of
a Director)  upon the written  request of the record  holders of at least 25% of
the  outstanding  shares  eligible  to be  voted at that  meeting.  The Fund has
undertaken  that it will then  either give the  applicants  access to the Fund's
shareholder list or mail the applicants' communication to all other shareholders
at the applicants' expense.

Deferred  Compensation  Plan.  The Board of  Directors  has  adopted a  Deferred
Compensation Plan for disinterested  trustees that enable 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  Director  is
periodically adjusted as though an equivalent amount had been invested in shares
of one or more Oppenheimer funds elected by the Director. The amount paid to the
Director  under the plan will be determined  based upon the  performance  of the
selected funds. Deferral of Director's fees under the
    

                                     -25-

plan will not materially  affect the Fund's assets,  liabilities  and net income
per share.  The plan will not  obligate  the fund to retain the  services of any
Director  or to pay  any  particular  level  of  compensation  to any  Director.
Pursuant to an Order issued by the Securities and Exchange Commission,  the Fund
may  invest  in the  funds  selected  by the  Director  under  the plan  without
shareholder  approval for the limited  purpose of  determining  the value of the
Director's deferred fee account.

     o Major  Shareholders.  To the  knowledge  of the Fund,  as of November 21,
1997,  no person owned  beneficially  5% or more of the  respective  outstanding
shares of either class of the Fund.
    

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

      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.

      o The Investment  Advisory  Agreement.  The investment  advisory agreement
between the  Manager  and the  Corporation  on behalf of the Fund  requires  the
Manager,  at its  expense,  to  provide  the Fund with  adequate  office  space,
facilities  and equipment  and to provide and  supervise  the  activities of all
administrative and clerical  personnel  required to provide effective  corporate
administration  for the Fund,  including  the  compilation  and  maintenance  of
records with respect to its operations,  the preparation and filing of specified
reports,  and  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
or by the Distributor under the General Distributor's  Agreement are paid by the
Fund.  The advisory  agreement  lists examples of expenses paid by the Fund, the
major categories of which relate to interest, taxes, brokerage commissions, fees
to certain  Trustees,  legal and audit  expenses,  custodian and transfer  agent
expenses,  share issuance costs,  certain  printing and  registration  costs and
non-recurring  expenses,  including  litigation costs.  During the Fund's fiscal
years ended June 30, 1995 and 1996,  its fiscal period ended August 31, 1996 and
its fiscal year ended August 31, 1997, the  management  fees paid by the Fund to
the Manager were $284,916, $330,555, $56,478 and $356,873, respectively.

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

      o The  Distributor.  Under its General  Distributor's  Agreement  with the
Corporation,  the Distributor acts as the Corporation's principal underwriter in
the continuous public offering of the Fund's Class A and Class B shares,  but is
not  obligated  to  sell  a  specific  number  of  shares.   Expenses   normally
attributable  to sales are borne by the  Distributor.  During the Fund's  fiscal
years ended June 30, 1995 and 1996,  its fiscal period ended August 31, 1996 and
its fiscal year ended August 31, 1997, the aggregate  amount of sales charges on
sales of the Fund's Class A shares was $177,634, $134,177, $24,568 and $293,130,
respectively,  of which  the  Distributor  retained  in the  aggregate  $28,801,
$28,111,  $4,283 and $46,207 in those respective years. During the Fund's fiscal
years ended June 30, 1995 and 1996,  its fiscal period ended August 31, 1996 and
its fiscal year ended August 31, 1997,  the  contingent  deferred  sales charges
collected  on the  Fund's  Class B shares  totaled  $6,447,  $3,991,  $2,863 and
$5,160,  respectively,  all of which the Distributor retained. During the fiscal
year ended August 31, 1997 commissions paid to broker-dealers by the Distributor
on  sales  of the  Fund's  Class  B  shares  totaled  $213,863.  For  additional
information about  distribution of the Fund's shares and the expenses  connected
with such activities, please refer to "Distribution and Service Plans," below.
    

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

Brokerage Policies of the Fund

   
Brokerage Provisions of the Investment Advisory Agreement.  One of the duties of
the  Manager   under  the  advisory   agreement  is  to  arrange  the  portfolio
transactions  for  the  Fund.  Most of the  Fund's  portfolio  transactions  are
principal  trades  without  brokerage  commissions.  If  brokers  are used,  the
advisory   agreement   contains   provisions   relating  to  the  employment  of
broker-dealers ("brokers") to effect the Fund's portfolio transactions. In doing
so,  the  Manager  is   authorized   by  the   advisory   agreement   to  employ
broker-dealers,  including  "affiliated" brokers, as that term is defined in the
Investment  Company  Act, as may,  in its best  judgment  based on all  relevant
factors,  implement the policy of the Fund to obtain, at reasonable expense, the
"best  execution"  (prompt and reliable  execution at the most  favorable  price
obtainable)  of  such  transactions.  The  Manager  need  not  seek  competitive
commission bidding, but is expected to be aware of the current rates of eligible
brokers and to minimize the commissions  paid to the extent  consistent with the
interests  and policies of the Fund as  established  by its Board of  Directors.
Purchases of  securities  from  underwriters  include a commission or concession
paid by the issuer to the  underwriter,  and  purchases  from dealers  include a
spread between the bid and asked price.
    

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


                                     -27-

<PAGE>



Description  of  Brokerage  Practices  Followed by the  Manager.  Subject to the
provisions of the advisory  agreement,  and the procedures  and rules  described
above,  allocations of brokerage are generally  made by the Manager's  portfolio
traders based upon  recommendations  from the Manager's portfolio  managers.  In
certain  instances,  portfolio  managers may directly  place trades and allocate
brokerage,  also subject to the  provisions  of the advisory  agreement  and the
procedures and rules  described  above.  In either case,  brokerage is allocated
under the  supervision  of the Manager's  executive  officers.  Transactions  in
securities  other than those for which an  exchange  is the  primary  market are
generally done with principals or market makers. In connection with transactions
on  foreign  exchanges,  the  Fund  may  be  required  to  pay  fixed  brokerage
commissions and thereby forego the benefit of negotiated  commissions  available
in  U.S.  markets.  Brokerage  commissions  are  paid  primarily  for  effecting
transactions   in  listed   securities  or  for  certain   fixed-income   agency
transactions in the secondary market,  and are otherwise paid only if it appears
likely that a better price or execution  can be obtained.  When the Fund engages
in an  option  transaction,  ordinarily  the  same  broker  will be used for the
purchase or sale of the option and any  transaction  in the  securities to which
the option  relates.  When possible,  concurrent  orders to purchase or sell the
same  security  by more than one of the  accounts  managed by the Manager or its
affiliates are combined.  The  transactions  effected  pursuant to such combined
orders are averaged as to price and allocated in accordance with the purchase or
sale  orders  actually  placed  for  each  account.  Option  commissions  may be
relatively  higher than those which would apply to direct purchases and sales of
portfolio securities.

      Most  purchases  of money  market  instruments  and debt  obligations  are
principal  transactions  at net  prices.  Instead  of using a broker  for  those
transactions,  the fund normally  deals  directly with the selling or purchasing
principal or market maker unless it determines  that a better price or execution
can  be  obtained  by  using  a  broker.   Purchases  of  these  securities  for
underwriters  include  a  commission  or  concession  paid by the  issuer to the
underwriter.  Purchases from dealers  include a spread between the bid and asked
prices.  The Fund seeks to obtain  prompt  execution of these orders at the most
favorable net price.

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

 
                                     -28-

<PAGE>


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

Performance of the Fund

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

Yields.

   
      o Standardized Yield. The "standardized yield" (referred to as "yield") is
shown  for a class of  shares  for a stated  30-day  period.  It is not based on
actual  distributions paid by the Fund to shareholders in the 30-day period, but
is a  hypothetical  yield based upon the net  investment  income from the Fund's
portfolio  investments  for  that  period.  It may  therefore  differ  from  the
"dividend yield" for the same class of shares, described below. It is calculated
using the  following  formula set forth in rules adopted by the  Securities  and
Exchange  Commission  designed  to assure  uniformity  in the way that all funds
calculate their yields: 
                                             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  reimbursements).  c = the
      average daily number of shares of that class outstanding during the 30-day
      period
           that were entitled to receive dividends.
      d    = the maximum  offering price per share of that class on the last day
           of the period, adjusted for undistributed net investment income.

   
      The standardized yield of a class of shares for a 30-day period may differ
from the yield for other periods.  The SEC formula  assumes that the yield for a
30-day period occurs at a constant rate for a six-month period and is annualized
at the end of the six-month period.  Additionally,  because each class of shares
is subject to different  expenses,  it is likely that the standardized yields of
the Fund's  classes of shares will differ for any 30 day period.  For the 30-day
period  ended  August 31, 1997 the  standardized  yields for the Fund's class of
shares were as follows:

           Without Deducting Sales Charge             With Sales Charge Deducted
Class A:   4.75%                                      4.53%
Class B:   3.74%                                      N/A
    

                                     -29-

<PAGE>



   
      o  Tax-Equivalent  Yield.  The Fund's  "tax-equivalent  yield" adjusts the
Fund's current yield,  as calculated  above,  by a stated  combined  Federal and
state tax rate.  The tax equivalent  yield is based on a 30-day  period,  and is
computed by dividing  the  tax-exempt  portion of the Fund's  current  yield (as
calculated above) by one minus a stated income tax rate and adding the result to
the portion (if any) of the Fund's  current  yield that is not  tax-exempt.  The
tax-equivalent  yield may be used to compare the tax  effects of income  derived
from the Fund with  income from  taxable  investments  at the tax rates  stated.
Appendix B includes a tax equivalent yield table, based on various effective tax
brackets  for  individual  taxpayers.  Such tax  brackets  are  determined  by a
taxpayer's  Federal and state taxable  income (the net amount subject to Federal
and state income tax after deductions and exemptions).  The tax-equivalent yield
tables assume 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.  For taxpayers  with income above  certain  levels,  otherwise  allowable
itemized deductions are limited. The For the 30-day period ended August 31, 1997
the Fund's  tax-equivalent  yield for Class A and Class B shares  were 8.27% and
6.83%, respectively, for an individual in the California/Federal combined 45.22%
tax bracket.

      o Dividend Yield.  The Fund may quote a "dividend yield" for each class of
shares.  Dividend  yield is based on the  dividends  paid on  shares  of a class
during the actual dividend  period.  from net investment  income during a stated
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 of the Class =

                             Dividends of the Class
              ----------------------------------------------------
              Max Offering Price of the Class (last day of period)

                               Divided by number of days (accrual period) x 365

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

      The dividend  yields for the 30-day  dividend period ended August 31, 1997
were as follows:

           Without Deducting Sales Charge             With Sales Charge Deducted
Class A:   5.79                                       5.52%
Class B:   4.75%                                      N/A
    

Total Return  Information.  The Fund's  advertisements  of its performance  data
must, under applicable rules of the Securities and Exchange Commission,  include
the average annual total returns for each advertised class of shares of the Fund
for the 1-, 5- and 10-year periods (or the life of the class, if less) ending as
of the most  recently-ended  calendar  quarter prior to the  publication  of the
advertisement. This enables an investor to compare the Fund's performance to the
performance  of other funds for the same periods.  However,  a number of factors
should be considered  before using such  information  as a basis for  comparison
with other  investments.  An investment in the Fund is not insured;  its returns
and share  prices are not  guaranteed  and  normally  will  fluctuate on a daily
basis.

                                     -30-

When  redeemed,  an  investor's  shares  may be worth  more or less  than  their
original  cost.  Returns  for any given  past  period  are not a  prediction  or
representation by the Fund of future returns. The returns of Class A and Class B
shares of the Fund are affected by portfolio  quality,  the type of  investments
the Fund holds and its operating expenses allocated to the particular class.

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

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


   
      The "average  annual total  returns" on an investment in Class A shares of
the Fund for the 1-and 5-year  periods  ended August 31, 1997 and for the period
from May 18, 1990  (commencement  of  operations) to August 31, 1997 were 5.01%,
6.18% and 7.44%, respectively.

      The "average  annual total return" on Class B shares for the 1-year period
ended August 31, 1997 and for the period October 29, 1993  (commencement  of the
public  offering  of the  class)  to August  31,  1997  were  4.23%  and  3.91%,
respectively.
    

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

   
      In calculating total returns for Class A shares, the current maximum sales
charge of 4.75% (as a  percentage  of the offering  price) is deducted  from the
initial  investment  ("P")  (unless the return is shown at net asset  value,  as
described below). For Class B shares,  the payment of the applicable  contingent
deferred sales charge (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)  is applied  to the  investment  result  for the period  shown
(unless  total return is shown at net asset value,  as described  below).  Total
returns also assume that all dividends and capital  gains  distributions  during
the period are reinvested to buy additional shares at net asset value per share,
and that the  investment is redeemed at the end of the period.  The  "cumulative
total  return" on an  investment in Class A shares of the Fund (using the method
described  above) for the period from May 18, 1990  (commencement of operations)
through  August 31,  1997 was 68.71%.  The  cumulative  total  return on Class B
shares for the period from October 29, 1993 (the commencement of the offering of
the shares) through August 31, 1997 was 15.84%.

     o Total  Returns  at Net Asset  Value.  From time to time the Fund may also
quote an "average annual total return at net asset value" or a "cumulative total
return at net asset  value" for Class A or Class B shares.  Each is based on the
difference  in net asset  value per  share at the  beginning  and the end of the
period  for  a  hypothetical   investment  in  that  class  of  shares  (without
considering  front-end  or  contingent  deferred  sales  charges) and takes into
consideration the reinvestment of dividends and capital gains distributions. The
average  annual  total  returns at net asset value for the Fund's Class A shares
for the one and five year  periods  ended August 31, 1997 and for the period May
18, 1990  (commencement  of  operations)  through  August 31, 1997 were  10.24%,
7.22%,  and 8.16%,  respectively.  The average annual total returns at net asset
value for the Fund's  Class B shares for the one year  period  ended  August 31,
1997 and for the period October 29, 1993  (commencement  of operations)  through
August 31, 1997 were 9.23% and 4.58%, respectively.  The cumulative total return
at net asset value on the Fund's  Class A shares for May 18, 1990  (commencement
of operations)  through August 31, 1997 was 77.13%.  The cumulative total return
at net asset value on the Fund's Class B shares for the period  October 29, 1993
(commencement of operations) through August 31, 1997 was 18.78%.
    

      Total return  information  may be useful to  investors  in  reviewing  the
performance of the Fund's Class A, and Class B shares.  However,  when comparing
total return of an investment in shares of the Fund, a number of factors  should
be considered before using such information as a basis for comparison with other
investments.  No  adjustment  is made for taxes  payable  on  distributions.  An
investment  in the  Fund's  shares  is not  insured;  its  total  return  is not
guaranteed and will fluctuate on a daily basis.  Total return for any given past
period is not an  indication  or  representation  by the Fund of future rates of
return on its  shares.  The total  return of the Fund's  shares is  affected  by
portfolio quality,  portfolio  maturity,  type of investments held and operating
expenses.  When  comparing  total return of an  investment in shares of the fund
with that of other  investment  instruments,  investors  should  understand that
certain  other  investment   alternatives  such  as  money  market  instruments,
certificates of deposit,  U.S. Government  securities or bank accounts provide a
return which remains  relatively  constant over time and also that bank accounts
may be insured.

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

   
      From  time  to  time,  the  Fund  may  publish  the  star  ranking  of the
performance  of its  Class  A and  Class  B  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 an  municipal  bond  funds,  based on  risk-adjusted  total
investment  returns.  The Fund is ranked among municipal bond funds.  Investment
return  measures a fund's or class' 1-, 3-, 5- and 10-year  average annual total
returns (depending on the inception of the fund or
    

                                     -32-

class) in excess of 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 the fund's  category.  Five stars is the  "highest"  ranking
(top 10%), four stars is "above average" (next 22.5%),  three stars is "average"
(next 35%),  two stars is "below  average" (next 22.5%) and one star is "lowest"
(bottom 10%). The current star ranking is the fund's or class' 3-year ranking or
its  combined 3- and 5-year  ranking  (weighted  60%/40%,  respectively,  or its
combined 3-, 5- and 10-year  ranking  (weighted 40%, 30% and 30%  respectively),
depending on the inception of the fund or class.  Rankings are subject to change
monthly.

      The Fund may also  compare its  performance  to that of other funds in its
Morningstar   Category.   In  addition  to  its  star  rankings,   Morningstar'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.
    

      The total return on an  investment in the Fund's Class A or Class B shares
may be compared  with  performance  for the same  period of the Lehman  Brothers
Municipal Bond Index,  as described in the  Prospectus.  The  performance of the
index includes a factor for the reinvestment of income  dividends,  but does not
reflect reinvestment of capital gains, expenses or taxes.

      The  performance  of the  Fund's  Class A or  Class B  shares  may also be
compared in  publications to (i) the performance of various market indices or to
other investments for which reliable performance data is available,  and (ii) to
averages, performance rankings or other benchmarks prepared by recognized mutual
fund statistical services.

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

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

Distribution and Service Plan

      
                                     -33-

<PAGE>


The Corporation  has adopted a Distribution  and Service Plan for Class B shares
of the Fund (the "Class B Plan") under Rule 12b-1 of the Investment  Company Act
pursuant to which the Corporation  will reimburse the Distributor  quarterly for
all or a portion  of its costs  incurred  in  connection  with the  distribution
and/or  servicing of Class B shares,  as described  in the  Prospectus.  Class A
shares  of the  Fund do not  have a plan of  distribution.  The  Plan  has  been
approved by a vote of (i) the Board of Directors of the Corporation, including a
majority of the "Independent  Directors," cast in person at a meeting called for
the  purpose of voting on that Plan,  and (ii) the holders of a  "majority"  (as
defined in the Investment  Company Act) of the Class B shares of the Fund,  such
vote  having  been cast by the  Manager  as the sole  initial  holder of Class B
shares of the Fund.

      In addition,  under the Class B Plan, the Manager and the Distributor,  in
their sole discretion,  from time to time may use their own resources (which, in
the case of the Manager,  may include  profits from the advisory fee it receives
from  the  Fund)  to make  payments  to  brokers,  dealers  or  other  financial
institutions  (each is referred to as a "Recipient"  under the Class B Plan) for
distribution and administrative  services they perform.  The Distributor and the
Manager  may,  in their sole  discretion,  increase  or  decrease  the amount of
payments they make from their own resources to Recipients.

      Unless  terminated as described  below, the Class B Plan shall continue in
effect from year to year but only as long as such  continuance  is  specifically
approved  at least  annually by the  Corporation's  Board of  Directors  and its
"Independent  Directors"  by a vote cast in person at a meeting  called  for the
purpose of voting on such continuance. The Class B Plan may be terminated at any
time by the vote of a majority of the  Independent  Directors  or by the vote of
the holders of a "majority"  (as defined in the  Investment  Company Act) of the
outstanding  Class B shares.  The Class B Plan may not be  amended  to  increase
materially the amount of payments to be made,  unless such amendment is approved
by shareholders of Class B shares.  All material  amendments must be approved by
the Independent Directors.

      While the Class B Plan is in  effect,  the  Treasurer  of the  Corporation
shall provide a written report to the Corporation's  Board of Directors at least
quarterly on the amount of all payments made  pursuant to the Class B Plan,  the
purpose for which  payments  were made and the  identity of each  Recipient of a
payment.  The report for the Class B Plan shall also  include  the  distribution
costs for that  quarter,  and such costs for  previous  fiscal  periods that are
carried  forward,  as  explained in the  Prospectus  and below.  Those  reports,
including the cost  allocations on which they are based,  will be subject to the
review and  approval  of the  Independent  Directors  in the  exercise  of their
fiduciary  duty.  The Class B Plan further  provides that while it is in effect,
the selection and nomination of those  Directors of the  Corporation who are not
"interested  persons" of the  Corporation  is committed to the discretion of the
Independent  Directors.  This does not prevent the involvement of others in such
selection  and  nomination  if the  final  decision  on any  such  selection  or
nomination is approved by a majority of the Independent Directors.

     Under the Class B Plan,  no payment  will be made to any  Recipient  in any
quarter  if the  aggregate  net  asset  value  of all  Fund  shares  held by the
Recipient for itself and its customer does not exceed a minimum amount,  if any,
that may be  determined  from  time to time by a  majority  of  theCorporation's
Independent  Directors.  The Board of  Directors  has set the fee at the maximum
rate and set no minimum amount.


                                     -34-

      The  Class  B Plan  allows  the  service  fee  payment  to be  paid by the
Distributor  to  Recipients  in  advance  for the first  year Class B shares are
outstanding,   and  thereafter  on  a  quarterly  basis,  as  described  in  the
Prospectus. The advance payment is based on the net assets of the Class B shares
sold. An exchange of shares does not entitle the Recipient to an advance service
fee payment. In the event Class B shares are redeemed during the first year such
shares are  outstanding,  the  Recipient  will be  obligated to repay a pro rata
portion of such advance payment to the Distributor.

   
      Although  the Class B Plan  permits  the  Distributor  to retain  both the
asset-based  sales  charges  and the  service  fee on Class B shares,  or to pay
Recipients the service fee on a quarterly basis, without payment in advance, the
Distributor intends to pay the service fee to Recipients in the manner described
above. A minimum  holding period may be established  from time to time under the
Class B Plan by the  Board.  Initially,  the  Board has set no  minimum  holding
period.  All  payments  under the Class B Plan are  subject  to the  limitations
imposed by the Conduct Rules of the National  Association of Securities Dealers,
Inc. on payments of  asset-based  sales charges and service fees. For the fiscal
period ended August 31, 1997,  payments under the Class B Plan totaled  $81,178,
of which the distributor retained $69,604 as reimbursement for the Class B sales
commissions and service fee advances, as well as financing costs.
    

      The Class B Plan allows for the carry-forward of distribution expenses, to
be recovered from  asset-based  sales charges in subsequent  fiscal periods,  as
described  in  the  Prospectus.   The  asset-based  sales  charge  paid  to  the
Distributor by the  Corporation  under the Class B Plan is intended to allow the
Distributor to recoup the cost of sales  commissions paid to authorized  brokers
and dealers at the time of sale,  plus  financing  costs,  as  described  in the
Prospectus.  Such payments may also be used to pay for the following expenses in
connection with the distribution of Class B shares: (i) financing the advance of
the service fee payment to Recipients under the Class B Plan, (ii)  compensation
and expenses of personnel employed by the Distributor to support distribution of
Class  B  shares,   and  (iii)  costs  of  sales  literature,   advertising  and
prospectuses  (other than those  furnished  to current  shareholders)  and state
"blue sky" registration fees.


ABOUT YOUR ACCOUNT

How To Buy Shares

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


                                     -35-

<PAGE>



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

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

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

Determination  of Net Asset Values Per Share.  The net asset values per share of
Class A and  Class B  shares  of the  Fund  are  determined  as of the  close of
business of The New York Stock  Exchange (the  "Exchange")  on each day that the
Exchange is open, by dividing value of the Fund's net assets  attributable  to a
class by the number of shares of that class that are  outstanding.  The Exchange
normally  closes at 4:00 P.M. New York time,  but may close earlier on some days
(for  example,  in case of  weather  emergencies  or on days  falling  before  a
holiday).  The Exchange's most recent annual holiday  schedule (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 on days on which the Exchange is
closed including weekends and holidays.  Because the Fund's net asset value will
not be calculated at those times, if securities held in the Fund's portfolio are
traded  at such  time,  the net  asset  values  per share of Class A and Class B
shares may be  significantly  affected  on such days when  shareholders  may not
purchase or redeem shares.

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

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

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

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

   
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 shares.  Dividends  will begin to accrue on shares  purchased by
the proceeds of ACH  transfers on the  business  day the Fund  receives  Federal
funds for 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 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 Rights of Accumulation and Letters
of Intent because of the economies of sales efforts and in expenses  realized by
the  Distributor,  dealers and brokers  making  such sales.  No sales  charge is
imposed  in  certain  circumstances  described  in the  Prospectus  because  the
Distributor,  dealer or broker  incurs little or no selling  expenses.  The term
"immediate  family" refers to one's spouse,  children,  grandchildren,  parents,
grandparents,   aunts,  uncles,  nieces,  nephews,  parents-in-law,   sons-  and
daughters-in law, siblings a sibling's spouse and a spouse's siblings. Relations
by virtue of a remarriage (step-children, step-parents, etc.) are included.

                                     -39-

<PAGE>


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

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

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

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

      o Terms of Escrow That Apply to Letters of Intent.

      1. Out of the initial purchase (or subsequent purchases if necessary) made
pursuant to a Letter, shares of the Fund equal in value up to 5% of the intended
purchase amount  specified in the Letter shall be held in escrow by the Transfer
Agent. For example, if the intended purchase amount is $50,000, the escrow shall
be shares valued in the amount of $2,500 (computed at the public


                                     -40-

<PAGE>



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 intended purchase amount specified under the Letter is completed
within the  thirteen-month  Letter of Intent period, the escrowed shares will be
promptly released to the investor.

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

      4. By  signing  the  Letter,  the  investor  irrevocably  constitutes  and
appoints the Transfer Agent as  attorney-in-fact to surrender for redemption any
or all escrowed shares.

      5. The shares  eligible for  purchase  under the Letter (or the holding of
which may be counted toward  completion of a Letter)  include (a) Class A shares
sold with a front-end  sales charge or subject to a Class A contingent  deferred
sales charge, (b) Class B shares acquired subject to a contingent deferred sales
charge, and (c) Class A shares or Class B shares acquired in exchange for either
(i) 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 (ii) Class B
shares of one of the other  Oppenheimer  funds that were  acquired  subject to a
contingent deferred sales charge.

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

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

      There is a front-end  sales charge on the purchase of certain  Oppenheimer
funds,  or a contingent  deferred sales charge may apply to shares  purchased by
Asset Builder payments.  An application should be obtained from the Distributor,
completed  and  returned,  and a prospectus  of the selected  fund(s)  should be
obtained from the Distributor or your financial  advisor before initiating Asset
Builder payments.  The amount of the Asset Builder  investment may be changed or
the  automatic  investments  may be  terminated  at any time by  writing  to the
Transfer Agent. A reasonable  period  (approximately  15 days) is required after
the Transfer Agent's receipt of such instructions to

                                     -41-

<PAGE>



implement  them. The Fund reserves the right to amend,  suspend,  or discontinue
offering such plans at any time without prior notice.

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

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

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

      o Involuntary  Redemptions.  The Board of Directors has the right to cause
the  involuntary  redemption  of the  shares  held in any  Fund  account  if the
aggregate  net asset  value of those  shares  is less  than $500 or such  lesser
amount  as the  Board  may fix.  The  Board of  Directors  will  not  cause  the
involuntary  redemption of shares in an account if the aggregate net asset value
of the shares has fallen below the stated  minimum  solely as a result of market
fluctuations. Should the Board elect to exercise this right, it may also fix, in
accordance with the Investment  Company Act, and the provisions of Maryland law,
the requirements for any notice to be given to the shareholders in question (not
less than 30 days),  or the Board may set  requirements  for the  Shareholder to
increase the  investment,  and set other terms and conditions so that the shares
would not be involuntarily redeemed.

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

   
      By choosing  the  Checkwriting  privilege,  whether done so by signing the
Account  Application  or by completing a Checkwriting  card,  the  individual(s)
signing (1) represent that they are either the
    

                                     -42-

<PAGE>



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

Reinvestment  Privilege.  Within six months of a redemption,  a shareholder  may
reinvest all or part of the  redemption  proceeds of (i) Class A shares that you
purchased  subject to an initial or contingent  deferred  sales charge,  or (ii)
Class B shares on which you paid a  contingent  deferred  sales  charge when you
redeemed them. 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  below,  at the net asset  value  next
computed  after  the  Transfer  Agent  receives  the  reinvestment   order.  The
shareholder  must  ask  the  Distributor  for  that  privilege  at the  time  of
reinvestment.  Any capital gain that was realized  when the shares were redeemed
is taxable,  and  reinvestment  will not alter any capital  gains tax payable on
that gain.  If there has been a capital loss on the  redemption,  some or all of
the loss may not be tax  deductible,  depending  on the timing and amount of the
reinvestment.  Under the Internal  Revenue Code, if the  redemption  proceeds of
Fund  shares on which a sales  charge was paid are  reinvested  in shares of the
Fund or another of the Oppenheimer  funds within 90 days of payment of the sales
charge, the shareholder's basis in the shares of the Fund that were redeemed may
not include the amount of the sales charge  paid.  That would reduce the loss or
increase the gain  recognized  from the  redemption.  However,  in that case the
sales  charge  would  be  added  to the  basis  of the  shares  acquired  by the
reinvestment of the redemption  proceeds.  The Fund may amend,  suspend or cease
offering this reinvestment privilege at any time as to shares redeemed after the
date of such amendment, suspension or cessation.

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

Special  Arrangements  for  Repurchase  of Shares from Dealers and Brokers.  The
Distributor is the Fund's agent to repurchase its shares from authorized dealers
or brokers on behalf of their  customers.  The  shareholder  should  contact the
broker or dealer to arrange this type of redemption.  The  repurchase  price per
share will be the net asset value next computed after the  Distributor  receives
the  order  placed by the  dealer  or  broker,  except  that if the  Distributor
receives a  repurchase  order from a dealer or broker after the close of The New
York Stock Exchange on a regular business day,

                                     -43-

<PAGE>



it will be  processed at that day's net asset value if the order was received by
the dealer or broker from its  customers  prior to the time the Exchange  closes
(normally,  that is 4:00 P.M. but may be earlier on some days) and the order was
transmitted  to and received by the  Distributor  prior to its close of business
that  day  (normally  5:00  P.M.).  Ordinarily,   for  accounts  redeemed  by  a
broker-dealer  under this procedure,  payment will be made within three business
days after the shares have been redeemed upon the  Distributor's  receipt of the
required  redemption  documents in proper  form,  with the  signature(s)  of the
registered  owners  guaranteed  on the  redemption  document as described in the
Prospectus.

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

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

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

      o Automatic Withdrawal Plans. Fund shares will be redeemed as necessary to
meet  withdrawal  payments.  Shares  acquired  without  a sales  charge  will be
redeemed first and 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
withdrawal  plans  should  not be  considered  as a  yield  or  income  on  your
investment. It may not be desirable to purchases additional Class A shares while
making  automatic  withdrawals  because  of the  sales  charges  that  apply  to
purchases when made. Accordingly, a shareholder normally may

                                     -44-

<PAGE>



not maintain an Automatic  Withdrawal Plan while  simultaneously  making regular
purchases of Class A shares.

   
      The Transfer Agent will  administer the  investor's  Automatic  Withdrawal
Plan (the "Plan") as agent for the investor (the  "Planholder") who executed the
Plan authorization and application submitted to the Transfer Agent. The Transfer
Agent and the Fund shall incur no  liability  to the  Planholder  for any action
taken or omitted by the  Transfer  Agent in good faith to  administer  the Plan.
Certificates  will not be issued for shares of the Fund  purchased  for and held
under the Plan,  but the  Transfer  Agent  will  credit  all such  shares to the
account of the  Planholder  on the records of the Fund.  Any share  certificates
held by a Planholder  may be  surrendered  unendorsed to the Transfer Agent with
the Plan  application so that the shares  represented by the  certificate may be
held under the Plan.
    

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

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

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

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

      To use Class A shares held under the Plan as  collateral  for a debt,  the
Planholder  may  request  issuance  of a  portion  of  the  Class  A  shares  in
certificated  form. Share  certificates are not issued for Class B shares.  Upon
written  request from the  Planholder,  the Transfer  Agent will  determine  the
number of Class A shares for which a certificate  may be issued without  causing
the  withdrawal  checks to stop because of exhaustion of  uncertificated  shares
needed to continue payments.  However,  should such uncertificated shares become
exhausted, Plan withdrawals will terminate.

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

How To Exchange Shares

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

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

      Class A shares of  Oppenheimer  funds may be  exchanged at net asset value
for shares of any money market fund.  Shares of any money market fund  purchased
without a sales charge may be exchanged for shares of Oppenheimer  funds offered
with a sales charge upon payment of the sales charge (or, if applicable,  may be
used to purchase  shares of Oppenheimer  funds subject to a contingent  deferred
sales charge).  However, shares of Oppenheimer Money Market Fund, Inc. purchased
with the  redemption  proceeds of shares of other mutual funds (other than funds
managed by the Manager or its subsidiaries) redeemed within the 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,
whichever  is  applicable.  To qualify for that  privilege,  the investor or the
investor's  dealer must notify the Distributor of eligibility for this privilege
at the time the shares of  Oppenheimer  Money Market Fund,  Inc. are  purchased,
and, if requested, must supply proof of entitlement to this privilege. Shares of
this Fund acquired by reinvestment  of dividends or distribution  from any other
of the  Oppenheimer  funds (except  Oppenheimer  Cash Reserves) or from any unit
investment  trust for which  reinvestment  arrangements  have been made with the
Distributor  may be  exchanged  at net  asset  value  for  shares  of any of the
Oppenheimer  funds. No contingent  deferred sales charge is imposed on exchanges
of shares of either  class  purchased  subject to a  contingent  deferred  sales
charge.  However,  when Class A shares acquired by exchange of Class A shares of
other Oppenheimer funds purchased subject to a Class A contingent deferred sales
charge are  redeemed  within 12 months of the end of the  calendar  month of the
initial  purchase of the exchanged Class A shares (18 months ro shares purchased
prior to May 1, 1997),  the Class A contingent  deferred sales charge is imposed
on the redeemed  shares (see "Class A Contingent  Deferred  Sales Charge" in the
Prospectus).  The Class B contingent deferred sales charge is imposed on Class B
shares acquired by exchange if they are redeemed within six years of the initial
purchase of the exchanged Class B shares.
    

      When Class B 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 contingent  deferred  sales charge will be followed in  determining  the
order in which the shares are exchanged.  Shareholders  should take into account
the  effect of any  exchange  on the  applicability  and rate of any  contingent
deferred

                                     -46-

<PAGE>



sales charge that might be imposed in the subsequent redemption of remaining 
shares.

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

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

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

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

Dividends, Capital Gains and Taxes

   
Dividends  and  Distributions.  During the Fund's  fiscal year ended  August 31,
1997, the Fund maintained the practice, to the extent consistent with the amount
of  the  Fund's  net  investment  income  and  other  distributable  income,  of
attempting to pay dividends on Class A shares at a constant  level of $.0611 per
share each month,  although the amount of such  dividends  was subject to change
from time to time depending on market conditions,  the composition of the Fund's
portfolio  and expenses  borne by the Fund.  On December 10, 1997,  the Board of
Directors  reduced the  dividend  rate for the Class A shares to $.054 per share
each month.  The practice of  attempting to pay dividends on Class A shares at a
constant  level  required the  Manager,  consistent  with the Fund's  investment
objective  and  investment  restrictions,  to monitor the Fund's  portfolio  and
select higher yielding  securities when deemed appropriate to maintain necessary
net investment  income levels.  This practice did not affect the net asset value
of the Fund's Class A shares. The Board of Directors may change the Fund's
    

                                     -47-

<PAGE>



   
targeted dividend level at any time,  without prior notice to shareholders;  the
Fund does not otherwise have a fixed dividend rate and there can be no assurance
as to the payment of any dividends or the realization of any capital gains.
    

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

Tax  Status of the  Fund's  Dividends  and  Distributions.  The Fund  intends to
qualify  under  the  Internal  Revenue  Code  during  each  fiscal  year  to pay
"exempt-interest dividends" to its shareholders. Exempt-interest dividends which
are  derived  from  net  investment  income  earned  by the  Fund  on  Municipal
Securities  will be  excludable  from gross income of  shareholders  for Federal
income tax purposes. Net investment income includes the allocation of amounts of
income from the Municipal Securities in the Fund's portfolio which are free from
Federal income taxes.  This allocation will be made by the use of one designated
percentage  applied uniformly to all income dividends made during the Fund's tax
year.  Such  designation  will normally be made following the end of each fiscal
year as to income  dividends  paid in the prior year.  The  percentage of income
designated as tax-exempt  may  substantially  differ from the  percentage of the
Fund's  income  that  was  tax-exempt  for a  given  period.  A  portion  of the
exempt-interest  dividends paid by the Fund may be an item of tax preference for
shareholders subject to the alternative minimum tax.

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

   
      If the Fund  qualifies  as a  "regulated  investment  company"  under  the
Internal Revenue Code, it will not be liable for Federal income taxes on amounts
paid by it as dividends  and  distributions.  The Fund  qualified as a regulated
investment  company  in its last  fiscal  year and  intends to qualify in future
years, but reserves the right not to qualify. The Internal Revenue Code contains
a number of complex tests to determine  whether the Fund will  qualify,  and the
Fund might not meet those tests in a  particular  year.  If it does not qualify,
the Fund will be treated for tax  purposes as an ordinary  corporation  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 and is exempt from Federal  income tax, (1) the
Fund will also be exempt  from the  California  corporate  income and  franchise
taxes and (2) the Fund will be  qualified  under  California  law to pay certain
exempt  interest  dividends  which will be exempt from the  California  personal
income tax. Individual shareholders of the Fund will generally not be subject to
California  personal income tax on  exempt-interest  dividends received from the
Fund to the extent such distributions are attributable to interest on California
Municipal Securities (and qualifying obligations of the United

                                     -48-

<PAGE>



States Government), provided that at least 50% of the Fund's assets at the close
of  each  quarter  of  its  taxable  year  are  invested  in  such  obligations.
Distributions  from the Fund  attributable  to  sources  other  than  California
Municipal  Securities will generally be taxable to such shareholders as ordinary
income.  In addition,  certain  distributions  to corporate  shareholders 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,  or
else the Fund must pay an excise tax on the amounts not distributed. While it is
presently  anticipated  that the Fund will meet those  requirements,  the Fund's
Board of Directors and the Manager might  determine in a particular year that it
would be in the best  interest  of  shareholders  for the Fund not to make  such
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.

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

      The Internal  Revenue Code  requires that a holder (such as the Fund) of a
zero coupon  security  accrue as income  each year a portion of the  discount at
which the  security  was  purchased  even  though the Fund  receives no interest
payment in cash on the security during the year. As an investment  company,  the
Fund must pay out substantially all of its net investment income each year or be
subject to excise taxes, as described  above.  Accordingly,  when the Fund holds
zero coupon securities,  it may be required to pay out as an income distribution
each year an amount which is greater than the total amount of cash  interest the
Fund actually  received during that year. Such  distributions  will be made from
the cash  assets  of the Fund or by  liquidation  of  portfolio  securities,  if
necessary. The Fund may realize a gain or loss from such sales. In the event the
Fund realizes net capital gains from such  transactions,  its  shareholders  may
receive a larger  capital  gain  distribution  than they  would  have had in the
absence of such transactions.

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

Additional Information About the Fund

The Custodian.  The Bank of New York is the Custodian of the Fund's assets.  The
Custodian's  responsibilities  include  safeguarding  and controlling the Fund's
portfolio securities  collecting income of the portfolio securities and handling
the delivery of securities to and from the Fund. The Manager has  represented to
the Fund that the banking  relationships  with the Custodian  have been and will
continue to be unrelated to and unaffected by the relationship  between the Fund
and the  Custodian.  It will  be the  practice  of the  Fund  to deal  with  the
Custodian in a manner uninfluenced by any banking

                                     -49-

<PAGE>



relationship  the  Custodian may have with the Manager and its  affiliates.  The
Fund's  cash  balances  within  the  custodian  in  excess of  $100,000  are not
protected by Federal deposit insurance. Those uninsured balances at times may be
substantial.

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

Independent Auditors' Report
- --------------------------------------------------------------------------------

================================================================================
The Board of Directors and Shareholders of Oppenheimer
Main Street California Municipal Fund:

We have audited the accompanying statement of assets and liabilities,  including
the statement of investments,  of Oppenheimer Main Street  California  Municipal
Fund as of August 31, 1997,  the related  statement of  operations  for the year
then ended, the statements of changes in net assets for the year then ended, for
the two months ended  August 31, 1996 and the year ended June 30, 1996,  and the
financial  highlights  for the  period  July 1, 1992 to August 31,  1997.  These
financial  statements  and financial  highlights are the  responsibility  of the
Fund's  management.  Our  responsibility  is to  express  an  opinion  on  these
financial statements and financial highlights based on our audits.

      We conducted our audits in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our procedures included  confirmation of securities owned at August
31, 1997 by correspondence with the custodian.  An audit also includes assessing
the accounting principles used and significant estimates made by management,  as
well as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.

      In our opinion, such financial statements and financial highlights present
fairly,  in all material  respects,  the financial  position of Oppenheimer Main
Street  California  Municipal  Fund at  August  31,  1997,  the  results  of its
operations,  the changes in its net assets, and the financial highlights for the
respective  stated  periods,  in conformity with generally  accepted  accounting
principles.

1.  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  $9,249,625  or 9.08% of the
Fund's net assets at August 31, 1997.

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

3.  Securities  with  an  aggregate   market  value  of  $418,726  are  held  in
collateralized  accounts to cover initial  margin  requirements  on open futures
sales contracts. See Note 5 of Notes to Financial Statements.

================================================================================
1. Significant Accounting Policies

Oppenheimer  Main  Street  California  Municipal  Fund (the  Fund) is a separate
series of Oppenheimer Main Street Funds, Inc., an open-end management investment
company  registered  under the Investment  Company Act of 1940, as amended.  The
Fund's  investment  objective is to seek as high a level of current income which
is exempt from  federal and  California  personal  income  taxes for  individual
investors  as  is  available  from  municipal  securities  and  consistent  with
preservation of capital. The Fund's investment adviser is OppenheimerFunds, Inc.
(the  Manager).  The Fund offers Class A and Class B shares.  Class A shares are
sold  with a  front-end  sales  charge.  Class  B  shares  may be  subject  to a
contingent  deferred sales charge.  Both 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 Directors. 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  Directors  to
determine  fair  value  in good  faith.  Short-term  "money  market  type"  debt
securities having a remaining maturity of 60 days or less are valued at cost (or
last  determined  market  value)  adjusted for  amortization  to maturity of any
premium or discount.

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

- --------------------------------------------------------------------------------
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.


              22 Oppenheimer Main Street California Municipal Fund
<PAGE>

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

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

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

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

      During  the  period  ended  August  31,  1997,   the  Fund   adjusted  the
classification  of  distributions  to  shareholders  to reflect the  differences
between financial  statement amounts and distributions  determined in accordance
with income tax  regulations.  Accordingly,  during the period  ended August 31,
1997,  amounts have been reclassified to reflect a decrease in undistributed net
investment income of $174,954.  Accumulated net realized gain on investments was
increased by the same amount.

- --------------------------------------------------------------------------------
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.  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.

3. Unrealized Gains and Losses on Investments

At August 31, 1997, net unrealized appreciation on investments of $2,709,986 was
composed  of  gross  appreciation  of  $3,854,592,  and  gross  depreciation  of
$1,144,606.

================================================================================
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 0.55% of average
annual net assets,  with a contractual waiver when net assets are less than $100
million.  Annual fees,  reflecting  this waiver,  are 0.40% of net assets of $75
million or more but less than $100  million,  0.25% of net assets of $50 million
or more but less than $75  million,  0.15% of net assets of $25  million or more
but less  than $50  million,  and 0% of net  assets  less than $25  million.  In
addition,  the  Manager  has  voluntarily  undertaken  to waive a portion of its
management fee, whereby the Fund shall pay an annual  management fee of 0.40% of
its average annual net assets in excess of $100 million.

      For the year ended August 31,  1997,  commissions  (sales  charges paid by
investors)  on sales of Class A shares  totaled  $293,130,  of which $46,207 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 shares
totaled  $213,863.  During  the  year  ended  August  31,  1997,  OFDI  received
contingent deferred sales charges of $5,160 upon redemption of Class B 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 Distribution and Service Plan for Class B shares to
reimburse  OFDI for its  services and costs in  distributing  Class B shares and
servicing  accounts.  Under the Plan,  the Fund pays OFDI an annual  asset-based
sales charge of 0.75% per year on Class B shares.  OFDI also  receives a service
fee of 0.25% per year to reimburse  dealers for providing  personal services for
accounts that hold Class B shares.  Both fees are computed on the average annual
net  assets  of Class B  shares,  determined  as of the  close  of each  regular
business day.  During the year ended August 31, 1997,  OFDI retained  $69,604 as
reimbursement for Class B sales commissions and service fee advances, as well as
financing  costs.  If the Plan is terminated by the Fund, the Board of Directors
may allow the Fund to continue  payments of the asset-based sales charge to OFDI
for distributing  shares before the Plan was terminated.  As of August 31, 1997,
OFDI had incurred unreimbursed expenses of $384,028 for Class B.

================================================================================
5. Futures Contracts

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

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

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

      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.

5. Futures Contracts  (continued)

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 August 31, 1997,  the Fund had  outstanding  futures  contracts to sell
debt securities as follows:

                       Description of Ratings Categories

Municipal Bonds

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

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

o Standard & Poor's  Corporation.  The ratings of Standard & Poor's  Corporation
("S&P") for Municipal  Bonds are AAA (Prime),  AA (High Grade),  A (Good Grade),
BBB (Medium Grade),  BB, B, CCC, CC, and C (speculative  grade).  Bonds rated in
the  top  four  categories  (AAA,  AA,  A,  BBB)  are  commonly  referred  to as
"investment  grade."  Municipal Bonds rated AAA are  "obligations of the highest
quality." The rating of AA is accorded  issues with  investment  characteristics
"only  slightly less marked than those of the prime quality  issues." The rating
of A describes  "the third  strongest  capacity  for  payment of debt  service."
Principal and interest  payments on bonds in this category are regarded as safe.
It  differs  from the two  higher  ratings  because,  with  respect  to  general
obligations bonds, there is some weakness, either in the local economic base, in
debt burden, in the balance

                                     A-1

<PAGE>



between revenues and  expenditures,  or in quality of management.  Under certain
adverse  circumstances,  any one such  weakness  might impair the ability of the
issuer to meet debt  obligations  at some future  date.  With respect to revenue
bonds,  debt service  coverage is good,  but not  exceptional.  Stability of the
pledged revenues could show some variations because of increased  competition or
economic influences on revenues. Basic security provisions,  while satisfactory,
are less stringent.  Management  performance appears adequate. The BBB rating is
the lowest  "investment grade" security rating. The difference between A and BBB
ratings is that the latter shows more than one fundamental weakness, or one very
substantial  fundamental weakness,  whereas the former shows only one deficiency
among the factors  considered.  With respect to revenue bonds,  debt coverage is
only fair.  Stability of the pledged  revenues could show  variations,  with the
revenue  flow  possibly  being  subject to erosion  over  time.  Basic  security
provisions are no more than adequate.  Management performance could be stronger.
Bonds  rated  "BB" have less  near-term  vulnerability  to  default  than  other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse  business,  financial,  or  economic  conditions  which  would  lead  to
inadequate capacity to meet timely interest and principal payments.  Bonds rated
"B" have a greater  vulnerability to default,  but currently has the capacity to
meet interest payments and principal repayments. Adverse business, financial, or
economic  conditions  will likely impair capacity or willingness to pay interest
and repay principal. Bonds rated "CCC" have a current identifiable vulnerability
to default,  and is dependent upon favorable business,  financial,  and economic
conditions to meet timely payment of interest and repayment of principal. In the
event of adverse business,  financial, or economic conditions,  it is not likely
to have the  capacity  to pay  interest  and repay  principal.  Bonds noted "CC"
typically  are debt  subordinated  to senior debt which is assigned on actual or
implied "CCC" debt  ratingBonds  rated "C" typically  are debt  subordinated  to
senior debt which is assigned an actual or implied  "CCC-" debt rating.  The "C"
rating may be used to cover a situation  where a  bankruptcy  petition  has been
filed, but debt service  payments are continued.  Bonds rated "D" are in payment
default.  The "D" rating  category is used when  interest  payments or principal
payments  are not made on the date due even if the  applicable  grace period has
not expired,  unless S&P  believes  that such  payments  will be made during the
grace  period.  The "D" rating also will be used upon the filing of a bankruptcy
petition if debt service  payments are  jeopardized.  The ratings from AA to CCC
may be  modified  by the  addition  of a plus or  minus  sign  to show  relative
standing within the major rating categories.

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

o Duff & Phelps'  The  ratings  of Duff & Phelps are as  follows:  AAA which are
judged to be the "highest  credit  quality".  The risk  factors are  negligible,
being only slightly more than for risk-free US Treasury debt. AA+, AA & AA- High
credit quality protection factors are strong. Risk is modest

                                     A-2

<PAGE>



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

Municipal Notes

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

      o S&P's  rating for  Municipal  Notes due in three years or less are SP-1,
SP-2,  and SP-3.  SP-1  describes  issues  with a very  strong  capacity  to pay
principal  and interest and compares with bonds rated A by S&P; if modified by a
plus sign, it compares with bonds rated 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.

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

Corporate Debt

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


                                     A-3

Commercial Paper

      o 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.

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

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

                                   Tax-Equivalent Yields

   
The equivalent  yield tables below compare  tax-free  income with taxable income
under Federal  individual  income tax rates,  and  California  state  individual
income tax rates effective January 1, 1997.  "Combined Taxable Income" refers to
the net amount subject to Federal and California  income taxes after  deductions
and exemptions. The tables assume that an investor's highest tax bracket applies
to the change in taxable  income  resulting  from a switch  between  taxable and
non-taxable  investments,  and that state tax payments are currently  deductible
for  Federal  tax  purposes  and that the  investor is not subject to Federal or
state  alternative  minimum tax. The income tax brackets are subject to indexing
in future years to reflect changes in the Consumer Price Index.  The brackets do
not reflect the  phaseout of itemized  deductions  and  personal  exemptions  at
higher  income  levels,  resulting  in  higher  effective  tax  rates  (and  tax
equivalent  yields).  For years beginning after January 1, 1996 the top marginal
California  personal tax rate was reduced to 9.3% and the top combined  marginal
tax rate is 45.22%.

Item 27. Indemnification

     Reference  is made to  paragraph  (b) of  Section 7 of  Article  SEVENTH of
Registrant's Articles of Incorporation filed as Exhibit 24(b)(1) hereto.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be  permitted to  Directors,  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 Director,  officer or  controlling  person of
Registrant  in the  successful  defense of any action,  suit or  proceeding)  is
asserted by such  Director,  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.

              AMENDED DISTRIBUTION AND SERVICE PLAN AND AGREEMENT

                                      WITH

                      OPPENHEIMER FUNDS DISTRIBUTOR, INC.

                             FOR CLASS B SHARES OF

                 OPPENHEIMER MAIN STREET INCOME & GROWTH FUND


DISTRIBUTION  AND SERVICE PLAN AND  AGREEMENT  (the "Plan") dated the 1st day of
October,  1994,  by  and  between  OPPENHEIMER  MAIN  STREET  FUNDS,  INC.  (the
"Corporation")  on behalf of  OPPENHEIMER  MAIN STREET INCOME & GROWTH FUND (the
"Fund"), a series of the Corporation,  and OPPENHEIMER FUNDS  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  (the
"Rule") under the Investment  Company Act of 1940 (the "1940 Act"),  pursuant to
which the Fund  will  compensate  the  Distributor  for a  portion  of its costs
incurred 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 Distributor is authorized  under
the  Plan  to pay  "Recipients,"  as  hereinafter  defined,  for  rendering  (a)
distribution  assistance  in  connection  with the  sale of  Shares  and/or  (b)
administrative  support  services with respect to Accounts.  Such Recipients are
intended to have certain  rights as third-party  beneficiaries  under 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  applicable  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 United States Securities and Exchange Commission.

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  service with respect to Shares held by Customers  (defined below)
      of the Recipient;

                                      1

<PAGE>


      (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.  Notwithstanding  the foregoing,  a majority of the Trust's Board of
      Directors  (the "Board") who are not  "interested  persons" (as defined in
      the 1940 Act) and who have no direct or indirect financial interest in the
      operation  of this Plan or in any  agreements  relating  to this Plan (the
      "Independent  Directors")  may remove any  broker,  dealer,  bank or other
      person or entity  as a  Recipient,  whereupon  such  entity's  rights as a
      third-party beneficiary hereunder shall terminate.

      (b) "Qualified Holdings" shall mean, as to any Recipient, all Shares owned
      beneficially or of record by: (i) such  Recipient,  or (ii) such brokerage
      or  other  customers  or  investment  advisory  or other  clients  of such
      Recipient  and/or  accounts as to which such  Recipient  is a fiduciary or
      custodian or co-fiduciary or co-custodian (collectively, the "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 two entities  would
      otherwise qualify as Recipients as to the same Shares, the Recipient which
      is the dealer of record on the Fund's books shall be deemed the  Recipient
      as to such Shares for purposes of this Plan.

3. Payments for Distribution Assistance and Administrative Support Services.

      (a) The Fund will make payments to the Distributor,  (i) within forty-five
      (45) days of the end of each calendar quarter,  in the aggregate amount of
      0.0625%  (0.25% on an annual  basis) of the  average  during the  calendar
      quarter of the aggregate net asset value of the Shares  computed as of the
      close of each business day (the "Service Fee"),  plus (ii) within ten (10)
      days of the end of each month,  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 six  years  or  less  (the
      "Maximum  Holding  Period").  Such Service Fee payments  received from the
      Fund  will   compensate  the  Distributor  and  Recipients  for  providing
      administrative  support  services  of the type  approved by the Board with
      respect to Accounts.  Such Asset-Based Sales Charge payments received from
      the Fund will  compensate  the  Distributor  and  Recipients for providing
      distribution assistance in connection with the sale of Shares.

      The administrative  support services in connection with the Accounts to be
      rendered  by  Recipients  may  include,  but shall not be limited  to, the
      following:  answering routine inquires  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.  The  distribution  assistance  in
      connection  with the sale of Shares to be rendered by the  Distributor and
      Recipients  may  include,  but shall not be  limited  to,  the  following:
      distributing  sales literature and prospectuses other than those furnished
      to current  holders of the Fund's Shares  ("Shareholders"),  and providing
      such other information and services in connection with the distribution of
      Shares as the  Distributor of the Fund may reasonably  request.  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 or Shares to 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
      the 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 either the Distributor or
      the  Board  still  is not  satisfied,  it may  take  appropriate  steps to
      terminate the  Recipient's  status as such under the Plan,  whereupon such
      entity's rights as a third-party beneficiary hereunder shall terminate.

      (b) The  Distributor  shall make  service fee  payments  to any  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, to be set from time to time by a majority of the
      Independent Directors.

      Alternatively,  the Distributor may, at its sole option,  make Service Fee
      payments  ("Advance  Service Fee  Payments") to any  Recipient  quarterly,
      within forty-five (45) days of the end of each calendar quarter, at a rate
      not to exceed (i) 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) 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,
      subject  to  reduction  or  chargeback  so that the  Advance  Service  Fee
      Payments do not exceed the limits on payments to  Recipients  that are, or
      may be,  imposed  by Rule  2830 of the  Conduct  Rules.  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, to be set from time
      to time by a majority of the  Independent  Directors.  The Advance Service
      Fee Payments  described in part (i) of the preceding  sentence may, at the
      Distributor's  sole option, 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 and will repay to 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.

      (c) A majority of the Independent Trustees may at any time or from time to
      time  increase or decrease  and  thereafter  adjust 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,  the  Minimum  Holding  Period  or  the  Minimum
      Qualified  Holdings.  The  Distributor  shall notify all Recipients of the
      Minimum  Qualified  Holdings,  Maximum  Holding Period or Minimum  Holding
      Period,  if  any,  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. 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.

      (d) The  Distributor is entitled to retain from the payments  described in
      Section  3(a)  the  aggregate  amount  of (i) the  Service  Fee on  Shares
      outstanding  for less  than the  Minimum  Holding  Period,  plus  (ii) the
      Asset-Based  Sales  Charge  on  Shares  outstanding  for not more than the
      Maximum  Holding  Period,  in each case  computed  as of the close of each
      business day during that period and subject to reduction or elimination of
      such amounts under the limits to which the  Distributor is, or may become,
      subject under Rule 2830 of the Conduct Rules.  Such amount is collectively
      referred to as the "Quarterly Limitation."

      The  distribution   assistance  and  administrative  support  services  in
      connection  with the sale of Shares to be rendered by the  Distributor 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 in advance of,  and/or  greater  than,  the
      amount   provided  for  in  Section  3  (b)  of  this  Plan;  (ii)  paying
      compensation  to and expenses of personnel of the  Distributor who support
      distribution  of Shares by Recipients;  (iii) paying of or reimbursing the
      Distributor for interest and other  borrowing costs on unreimbursed  Carry
      Forward  Expenses  (as  hereafter   defined)  at  the  rate  paid  by  the
      Distributor or, if such amounts are financed by the  Distributor  from its
      own  resources or by an  affiliate,  at the rate of 1% per annum above the
      prime  rate  (which  shall  mean the most  preferential  interest  rate on
      corporate  loans at large U.S. money center  commercial  banks) then being
      reported  in the Eastern  edition of the Wall  Street  Journal (or if such
      prime rate is no longer so reported,  such other rate as may be designated
      from time to time by the Distributor  with the approval of the Independent
      Directors);  (iv) other direct  distribution costs of the type approved by
      the Board,  including  without  limitation the costs of sales  literature,
      advertising  and  prospectuses  (other  than  those  furnished  to current
      Shareholders)  and state  "blue sky"  registration  expenses;  and (v) any
      service  rendered by the Distributor  that a Recipient may render pursuant
      to part (a) of this Section 3.

      The  Distributor's  costs of providing  the  above-mentioned  services are
      hereinafter  collectively referred to as "Distribution and Service Costs."
      "Carry Forward  Expenses" are  Distribution and Service Costs that are not
      paid in the fiscal  quarter in which they arise  because  they  exceed the
      Quarterly  Limitation.  In the event that the Board  should have reason to
      believe 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.

      (e) The excess in any fiscal quarter of (i) the Quarterly  Limitation plus
      any contingent  deferred sales charge ("CDSC")  payments  recovered by the
      Distributor on the proceeds of redemption of Shares over (ii) Distribution
      and Service Costs during that  quarter,  shall be applied in the following
      order of  priority:  first  to  interest  on  unreimbursed  Carry  Forward
      Expenses,  second to reduce any unreimbursed Carry Forward Expenses, third
      to reduce  Distribution and Service Costs during that quarter,  and fourth
      to  reduce  the  Asset-Based  Sales  Charge  payments  by the  Fund to the
      Distributor  in that  quarter.  Carry  Forward  Expenses  shall be carried
      forward  by the  Fund  until  payment  can be  made  under  the  Quarterly
      Limitation.

      (f)  Under  the  Plan,  payments  may  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 its borrowings.

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

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
distribution  expenditures  properly  attributable to the Shares,  including the
amount of all payments made pursuant to this Plan, the identity of the Recipient
of each such payment,  the amount paid to the Distributor,  and the Distribution
and Service Costs and Carry Forward  Expenses for that period.  The report shall
state whether all  provisions of Section 3 of this Plan have been complied with.
The  Distributor  shall  annually  certify  to the Board the amount of its total
expenses  incurred that year and its total expenses  incurred in prior years and
not  previously  recovered  with  respect  to  the  distribution  of  Shares  in
conjunction with the Board's annual review of the continuation of the Plan.

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
Directors  or by a vote of the holders of a  "majority"  (as defined in the 1940
Act) of the Fund's  outstanding voting securities of the Class, on not more than
sixty  days  written  notice  to any  other  party to the  agreement;  (ii) such
agreement  shall  automatically  terminate  in the event of its  assignment  (as
defined in the 1940 Act);  (iii) it shall go into effect when approved by a vote
of the Board and its  Independent  Directors  cast in person at a meeting called
for the  purpose  of  voting  on such  agreement;  and  (iv)  it  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  Directors cast in person at a meeting called for the
purpose of voting on such continuance.

7. Effectiveness,  Continuation,  Termination and Amendment.  This Plan has been
approved by a vote of the Board and its Independent  Directors cast in person at
a meeting  called on June 28, 1994 for the  purpose of voting on this Plan,  and
takes effect as of October 1, 1994. Unless  terminated as hereinafter  provided,
it  shall  continue  in  effect  year to year  thereafter  or as the  Board  may
otherwise determine only so long as such continuance is specifically approved at
least  annually  by a vote of the Board and its  Independent  Directors  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
without approval of the Class B Shareholders, in the manner described above, and
all  material  amendments  must be  approved  by a vote of the  Board and of the
Independent  Directors.  This  Plan may be  terminated  at any time by vote of a
majority  of the  Independent  Directors  or by the  vote  of the  holders  of a
"majority"  (as  defined  in the  1940  Act) of the  Fund's  outstanding  voting
securities  of the Class.  In the event of such  termination,  the Board and its
Independent  Directors  shall  determine  whether the Distributor is entitled to
payment from the Fund of all Carry Forward  Expenses and related costs  properly
incurred  in  respect  of  Shares  sold  prior  to the  effective  date  of such
termination,  and  whether  the  Fund  shall  continue  to make  payment  to the
Distributor  in the amount the  Distributor is entitled to retain under part (d)
of Section 3 hereof,  until such time as the Distributor has been reimbursed for
all such amounts by the Fund, by retaining CDSC payments, or by a combination of
both.

                      OPPENHEIMER FUNDS DISTRIBUTOR, INC.

                             FOR CLASS C SHARES OF

                 OPPENHEIMER MAIN STREET INCOME & GROWTH FUND


DISTRIBUTION  AND SERVICE PLAN AND  AGREEMENT  (the "Plan") dated the 1st day of
December,  1993,  by and  between  OPPENHEIMER  MAIN  STREET  FUNDS,  INC.  (the
"Corporation")  on behalf of  OPPENHEIMER  MAIN STREET INCOME & GROWTH FUND (the
"Fund"), a series of the Corporation,  and OPPENHEIMER FUNDS  DISTRIBUTOR,  INC.
(the "Distributor").

1. The Plan. This Plan is the Fund's written  distribution  and service plan for
Class C shares of the Fund  (the  "Shares"),  contemplated  by Rule  12b-1  (the
"Rule") under the Investment  Company Act of 1940 (the "1940 Act"),  pursuant to
which the Fund  will  compensate  the  Distributor  for a  portion  of its costs
incurred 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 Distributor is authorized  under
the  Plan  to pay  "Recipients,"  as  hereinafter  defined,  for  rendering  (a)
distribution  assistance  in  connection  with the  sale of  Shares  and/or  (b)
administrative  support  services with respect to Accounts.  Such Recipients are
intended to have certain  rights as third-party  beneficiaries  under 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  applicable  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 United States Securities and Exchange Commission.

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  service with respect to Shares held by Customers  (defined below)
      of the Recipient;

                                      1

<PAGE>


      (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.  Notwithstanding  the  foregoing,  a majority of the Fund's Board of
      Directors  (the "Board") who are not  "interested  persons" (as defined in
      the 1940 Act) and who have no direct or indirect financial interest in the
      operation  of this Plan or in any  agreements  relating  to this Plan (the
      "Independent  Directors")  may remove any  broker,  dealer,  bank or other
      person or entity  as a  Recipient,  whereupon  such  entity's  rights as a
      third-party beneficiary hereunder shall terminate.

      (b) "Qualified Holdings" shall mean, as to any Recipient, all Shares owned
      beneficially or of record by: (i) such  Recipient,  or (ii) such brokerage
      or  other  customers  or  investment  advisory  or other  clients  of such
      Recipient  and/or  accounts as to which such  Recipient  is a fiduciary or
      custodian or co-fiduciary or co-custodian (collectively, the "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 two entities  would
      otherwise qualify as Recipients as to the same Shares, the Recipient which
      is the dealer of record on the Fund's books shall be deemed the  Recipient
      as to such Shares for purposes of this Plan.

3. Payments for Distribution Assistance and Administrative Support Services.

      (a) The Fund will make payments to the Distributor, within forty-five (45)
      days of the end of each calendar  quarter,  (i) in the aggregate amount of
      0.0625%  (0.25% on an annual  basis) of the  average  during the  calendar
      quarter of the aggregate net asset value of the Shares  computed as of the
      close of each business day (the "Service  Fee"),  plus (ii) 0.1875% (0.75%
      on an annual  basis) of the  average  during the  calendar  quarter of the
      aggregate  net asset value of the Shares  computed as of the close of each
      business day (the "Asset-Based  Sales Charge").  Such Service Fee payments
      received from the Fund will  compensate the Distributor and Recipients for
      providing  administrative  support  services  of the type  approved by the
      Board with respect to Accounts.  Such  Asset-Based  Sales Charge  payments
      received from the Fund will  compensate the Distributor and Recipients for
      providing distribution assistance in connection with the sale of Shares.

      The administrative  support services in connection with the Accounts to be
      rendered  by  Recipients  may  include,  but shall not be limited  to, the
      following:  answering routine inquires  concerning the Fund,  assisting in
      establishing  and  maintaining  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  of  the  Fund  may  reasonably   request.   The  distribution
      assistance  in  connection  with  the sale of  Shares  to be  rendered  by
      Recipients  may  include,  but shall not be  limited  to,  the  following:
      distributing  sales literature and prospectuses other than those furnished
      to current  holders of the Fund's Shares  ("Shareholders"),  and providing
      such other information and services in connection with the distribution of
      Shares as the  Distributor of the Fund may reasonably  request.  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 or Shares to 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
      the 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 either the Distributor or
      the  Board  still  is not  satisfied,  it may  take  appropriate  steps to
      terminate the  Recipient's  status as such under the Plan,  whereupon such
      entity's rights as a third-party beneficiary hereunder shall terminate.

      (b) (i) Service Fees. The  Distributor  shall make service fee payments to
      any 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, to be set from time to time by a
      majority of the Independent Directors.

      Alternatively,  the Distributor may, at its sole option,  make service fee
      payments  ("Advance  Service Fee  Payments") to any  Recipient  quarterly,
      within forty-five (45) days of the end of each calendar quarter, at a rate
      not to exceed (A) 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) 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,
      subject  to  reduction  or  chargeback  so that the  Advance  Service  Fee
      Payments do not exceed the limits on payments to  Recipients  that are, or
      may be,  imposed  by Rule  2830 of the NASD  Conduct  Rules.  The  Advance
      Service Fee Payments  described in part (A) of the preceding sentence may,
      at the Distributor's  sole option, 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 and will repay to 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.

      (ii) Asset-Based Sales Charge Payments.  Irrespective of which alternative
      method  of  service  fee  payment  is  selected  by the  Distributor,  the
      Distributor  shall make asset-based sales charge payments to any Recipient
      quarterly,  within  forty-five  (45)  days  of 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. However, no such service
      fee or asset-based  sales charge  payments  (collectively,  the "Recipient
      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, to be set from
      time to time by a majority of the Independent Directors.


      (c) A majority of the  Independent  Directors may at any time or from time
      to time increase or decrease and thereafter  adjust 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
      Minimum Holding Period or the Minimum Qualified Holdings.  The Distributor
      shall notify all Recipients of the Minimum  Qualified  Holdings or Minimum
      Holding  Period,  if any,  and the rates of Recipient  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. 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.

      (d) The  Distributor is entitled to retain from the payments  described in
      Section 3(a) the aggregate amount of (i) the
      Service  Fee on  Shares  outstanding  for less  than the  Minimum  Holding
      Period,  (ii) the Asset-Based  Sales Charge on Shares  outstanding for not
      more than the one (1) year,  plus (iii) any additional  Asset-Based  Sales
      Charge  payment  which no  Recipient  qualifies  to receive,  in each case
      computed  as of the close of each  business  day  during  that  period and
      subject to reduction or  elimination  of such amounts  under the limits to
      which the  Distributor  is, or may become,  subject under Rule 2830 of the
      NASD  Conduct  Rules.  Such  amount  is  collectively  referred  to as the
      "Quarterly Limitation."

      The  distribution   assistance  and  administrative  support  services  in
      connection  with the sale of Shares to be rendered by the  Distributor 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 in
      advance of, and/or greater than,  the amount  provided for in Section 3(b)
      of this Plan; (ii) paying compensation to and expenses of personnel of the
      Distributor who support distribution of Shares by Recipients; (iii) paying
      of or reimbursing  the  Distributor for interest and other borrowing costs
      on unreimbursed  Carry Forward Expenses (as hereafter defined) at the rate
      paid  by  the  Distributor  or,  if  such  amounts  are  financed  by  the
      Distributor  from its own resources or by an affiliate,  at the rate of 1%
      per annum  above the prime rate  (which  shall mean the most  preferential
      interest  rate on corporate  loans at large U.S.  money center  commercial
      banks)  then being  reported  in the  Eastern  edition of the Wall  Street
      Journal (or if such prime rate is no longer so  reported,  such other rate
      as may be  designated  from  time  to  time by the  Distributor  with  the
      approval of the  Independent  Directors);  (iv) other direct  distribution
      costs of the type approved by the Board,  including without limitation the
      costs of sales literature,  advertising and prospectuses (other than those
      furnished  to current  Shareholders)  and state  "blue  sky"  registration
      expenses; and (v) any service rendered by the Distributor that a Recipient
      may render pursuant to part (a) of this Section 3.

      The  Distributor's  costs of providing  the  above-mentioned  services are
      hereinafter  collectively referred to as "Distribution and Service Costs."
      "Carry Forward  Expenses" are  Distribution and Service Costs that are not
      paid in the quarter in which they arise  because they exceed the Quarterly
      Limitation. In the event that the Board should have reason to believe 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.

      (e)   The excess in any quarter of (i) the Quarterly Limitation
      plus any contingent  deferred sales charge ("CDSC") payments  recovered by
      the  Distributor  on the  proceeds  of  redemption  of  Shares  over  (ii)
      Distribution  and Service Costs during that  quarter,  shall be applied in
      the following order of priority:  first to interest on unreimbursed  Carry
      Forward  Expenses,   second  to  reduce  any  unreimbursed  Carry  Forward
      Expenses,  third to reduce  Distribution  and  Service  Costs  during that
      quarter,  and fourth,  to reduce the Asset Based Sales Charge  payments by
      the Fund to the Distributor in that quarter.  Carry Forward Expenses shall
      be  carried  forward  by the Fund  until  payment  can be made  under  the
      Quarterly Limitation.

      (f)  Under  the  Plan,  payments  may  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 its borrowings.

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

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
distribution  expenditures  properly  attributable to the Shares,  including the
amount of all payments made pursuant to this Plan, the identity of the Recipient
of each such payment,  the amount paid to the Distributor,  and the Distribution
and Service Costs and Carry Forward  Expenses for that period.  The report shall
state whether all  provisions of Section 3 of this Plan have been complied with.
The  Distributor  shall  annually  certify  to the Board the amount of its total
expenses  incurred that year and its total expenses  incurred in prior years and
not  previously  recovered  with  respect  to  the  distribution  of  Shares  in
conjunction with the Board's annual review of the continuation of the Plan.

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
Directors  or by a vote of the holders of a  "majority"  (as defined in the 1940
Act) of the Fund's  outstanding voting securities of the Class, on not more than
sixty  days  written  notice  to any  other  party to the  agreement;  (ii) such
agreement  shall  automatically  terminate  in the event of its  assignment  (as
defined in the 1940 Act);  (iii) it shall go into effect when approved by a vote
of the Board and its  Independent  Directors  cast in person at a meeting called
for the purpose of
voting  on such  agreement;  and (iv) it  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  Directors  cast in person at a meeting  called  for the  purpose of
voting on such continuance.

7. Effectiveness,  Continuation,  Termination and Amendment.  This Plan has been
approved by a vote of the Board and its Independent  Directors cast in person at
a meeting called on October 26, 1993 for the purpose of voting on this Plan, and
takes  effect  as of the date  first  set  forth  above.  Unless  terminated  as
hereinafter  provided,  it shall  continue  in effect from year to year from the
date first set forth above or as the Board may otherwise  determine only so long
as such continuance is specifically  approved at least annually by a vote of the
Board and its  Independent  Directors 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  without  approval of the Class C
Shareholders, in the manner described above, and all material amendments must be
approved by a vote of the Board and of the Independent Directors.  This Plan may
be terminated at any time by vote of a majority of the Independent  Directors or
by the vote of the holders of a  "majority"  (as defined in the 1940 Act) of the
Fund's  outstanding  voting  securities  of the  Class.  In the  event  of  such
termination, the Board and its Independent Directors shall determine whether the
Distributor  is entitled to payment from the Fund of all Carry Forward  Expenses
and  related  costs  properly  incurred  in respect of Shares  sold prior to the
effective date of such termination,  and whether the Fund shall continue to make
payment to the  Distributor in the amount the  Distributor is entitled to retain
under part (d) of Section 3 hereof,  until such time as the Distributor has been
reimbursed for all such amounts by the Fund, by retaining CDSC payments, or by a
combination of both.

                                      WITH

                      OPPENHEIMER FUNDS DISTRIBUTOR, INC.

                             FOR CLASS B SHARES OF

               OPPENHEIMER MAIN STREET CALIFORNIA MUNICIPAL FUND


DISTRIBUTION  AND SERVICE PLAN AND AGREEMENT  (the "Plan") dated the 23rd day of
February,  1994,  by and  between  OPPENHEIMER  MAIN  STREET  FUNDS,  INC.  (the
"Corporation")  on behalf of OPPENHEIMER MAIN STREET  CALIFORNIA  MUNICIPAL FUND
(the "Fund"),  a series of the Corporation,  and OPPENHEIMER FUNDS  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  (the
"Rule") under the Investment  Company Act of 1940 (the "1940 Act"),  pursuant to
which the Fund  will  compensate  the  Distributor  for a  portion  of its costs
incurred 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 Distributor is authorized  under
the  Plan  to pay  "Recipients,"  as  hereinafter  defined,  for  rendering  (a)
distribution  assistance  in  connection  with the  sale of  Shares  and/or  (b)
administrative  support  services with respect to Accounts.  Such Recipients are
intended to have certain  rights as third-party  beneficiaries  under 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  applicable  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 United States Securities and Exchange Commission.

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  service with respect to Shares held by Customers  (defined below)
      of the Recipient;

                                      1

<PAGE>



      (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.
      Notwithstanding  the  foregoing,  a  majority  of  the  Trust's  Board  of
      Directors  (the "Board") who are not  "interested  persons" (as defined in
      the 1940 Act) and who have no direct or indirect financial interest in the
      operation  of this Plan or in any  agreements  relating  to this Plan (the
      "Independent  Directors")  may remove any  broker,  dealer,  bank or other
      person or entity  as a  Recipient,  whereupon  such  entity's  rights as a
      third-party beneficiary hereunder shall terminate.

      (b) "Qualified Holdings" shall mean, as to any Recipient, all Shares owned
      beneficially or of record by: (i) such  Recipient,  or (ii) such brokerage
      or  other  customers  or  investment  advisory  or other  clients  of such
      Recipient  and/or  accounts as to which such  Recipient  is a fiduciary or
      custodian or co-fiduciary or co-custodian (collectively, the "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 two entities  would
      otherwise qualify as Recipients as to the same Shares, the Recipient which
      is the dealer of record on the Fund's books shall be deemed the  Recipient
      as to such Shares for purposes of this Plan.

3. Payments for Distribution Assistance and Administrative Support Services.

      (a) The Fund will make payments to the Distributor,  (i) within forty-five
      (45) days of the end of each calendar quarter,  in the aggregate amount of
      0.0625%  (0.25% on an annual  basis) of the  average  during the  calendar
      quarter of the aggregate net asset value of the Shares  computed as of the
      close of each business day (the "Service Fee"),  plus (ii) within ten (10)
      days of the end of each month,  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 six  years  or  less  (the
      "Maximum  Holding  Period").  Such Service Fee payments  received from the
      Fund  will   compensate  the  Distributor  and  Recipients  for  providing
      administrative  support  services  of the type  approved by the Board with
      respect to Accounts.  Such Asset-Based Sales Charge payments received from
      the Fund will  compensate  the  Distributor  and  Recipients for providing
      distribution assistance in connection with the sale of Shares.

      The administrative support services in connection with the
      Accounts to be rendered by Recipients may include, but shall
      not be limited to, the following:  answering routine inquires

                                      2

<PAGE>



      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.  The
      distribution  assistance  in  connection  with  the sale of  Shares  to be
      rendered by the Distributor  and Recipients may include,  but shall not be
      limited to, the following:  distributing sales literature and prospectuses
      other  than those  furnished  to  current  holders  of the  Fund's  Shares
      ("Shareholders"),  and providing  such other  information  and services in
      connection with the  distribution of Shares as the Distributor of the Fund
      may reasonably  request.  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 or Shares to 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
      the 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 either the Distributor or
      the  Board  still  is not  satisfied,  it may  take  appropriate  steps to
      terminate the  Recipient's  status as such under the Plan,  whereupon such
      entity's rights as a third-party beneficiary hereunder shall terminate.

      (b) The  Distributor  shall make  service fee  payments  to any  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, to be set from time to time by a majority of the
      Independent Directors.

      Alternatively,  the Distributor may, at its sole option,  make Service Fee
      payments  ("Advance  Service Fee  Payments") to any  Recipient  quarterly,
      within forty-five (45) days of the end of each calendar quarter, at a rate
      not to exceed (i) 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

                                      3

<PAGE>



      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)  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,
      subject  to  reduction  or  chargeback  so that the  Advance  Service  Fee
      Payments do not exceed the limits on payments to  Recipients  that are, or
      may be,  imposed  by Rule  2830 of the  Conduct  Rules.  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, to be set from time
      to time by a majority of the  Independent  Directors.  The Advance Service
      Fee Payments  described in part (i) of the preceding  sentence may, at the
      Distributor's  sole option, 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 and will repay to 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.

      (c) A majority of the Independent Trustees may at any time or from time to
      time  increase or decrease  and  thereafter  adjust 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,  the  Minimum  Holding  Period  or  the  Minimum
      Qualified  Holdings.  The  Distributor  shall notify all Recipients of the
      Minimum  Qualified  Holdings,  Maximum  Holding Period or Minimum  Holding
      Period,  if  any,  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. 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.

      (d) The  Distributor is entitled to retain from the payments  described in
      Section  3(a)  the  aggregate  amount  of (i) the  Service  Fee on  Shares
      outstanding  for less  than the  Minimum  Holding  Period,  plus  (ii) the
      Asset-Based  Sales  Charge  on  Shares  outstanding  for not more than the
      Maximum  Holding  Period,  in each case  computed  as of the close of each
      business day during that period and subject to reduction or elimination of
      such amounts under the limits to which the Distributor is,

                                      4

<PAGE>



      or may become, subject under Rule 2830 of the NASD Conduct
      Rules.  Such amount is collectively referred to as the
      "Quarterly Limitation."

      The  distribution   assistance  and  administrative  support  services  in
      connection  with the sale of Shares to be rendered by the  Distributor 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 in
      advance of, and/or greater than, the amount  provided for in Section 3 (b)
      of this Plan; (ii) paying compensation to and expenses of personnel of the
      Distributor who support distribution of Shares by Recipients; (iii) paying
      of or reimbursing  the  Distributor for interest and other borrowing costs
      on unreimbursed  Carry Forward Expenses (as hereafter defined) at the rate
      paid  by  the  Distributor  or,  if  such  amounts  are  financed  by  the
      Distributor  from its own resources or by an affiliate,  at the rate of 1%
      per annum  above the prime rate  (which  shall mean the most  preferential
      interest  rate on corporate  loans at large U.S.  money center  commercial
      banks)  then being  reported  in the  Eastern  edition of the Wall  Street
      Journal (or if such prime rate is no longer so  reported,  such other rate
      as may be  designated  from  time  to  time by the  Distributor  with  the
      approval of the  Independent  Directors);  (iv) other direct  distribution
      costs of the type approved by the Board,  including without limitation the
      costs of sales literature,  advertising and prospectuses (other than those
      furnished  to current  Shareholders)  and state  "blue  sky"  registration
      expenses; and (v) any service rendered by the Distributor that a Recipient
      may render pursuant to part (a) of this Section 3.

      The  Distributor's  costs of providing  the  above-mentioned  services are
      hereinafter  collectively referred to as "Distribution and Service Costs."
      "Carry Forward  Expenses" are  Distribution and Service Costs that are not
      paid in the quarter in which they arise  because they exceed the Quarterly
      Limitation. In the event that the Board should have reason to believe 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.

      (e) The excess in any  quarter of (i) the  Quarterly  Limitation  plus any
      contingent  deferred  sales  charge  ("CDSC")  payments  recovered  by the
      Distributor on the proceeds of redemption of Shares over (ii) Distribution
      and Service Costs during that  quarter,  shall be applied in the following
      order of  priority:  first  to  interest  on  unreimbursed  Carry  Forward
      Expenses,

                                      5

      second to reduce any unreimbursed Carry Forward Expenses,  third to reduce
      Distribution  and Service Costs during that quarter,  and fourth to reduce
      the  Asset-Based  Sales Charge  payments by the Fund to the Distributor in
      that quarter.  Carry Forward Expenses shall be carried forward by the Fund
      until payment can be made under the Quarterly Limitation.

      (f)  Under  the  Plan,  payments  may  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 its borrowings.

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

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
distribution  expenditures  properly  attributable to the Shares,  including the
amount of all payments made pursuant to this Plan, the identity of the Recipient
of each such payment,  the amount paid to the Distributor,  and the Distribution
and Service Costs and Carry Forward  Expenses for that period.  The report shall
state whether all  provisions of Section 3 of this Plan have been complied with.
The  Distributor  shall  annually  certify  to the Board the amount of its total
expenses  incurred that year and its total expenses  incurred in prior years and
not  previously  recovered  with  respect  to  the  distribution  of  Shares  in
conjunction with the Board's annual review of the continuation of the Plan.

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
Directors  or by a vote of the holders of a  "majority"  (as defined in the 1940
Act) of the Fund's  outstanding voting securities of the Class, on not more than
sixty  days  written  notice  to any  other  party to the  agreement;  (ii) such
agreement  shall  automatically  terminate  in the event of its  assignment  (as
defined in the 1940 Act);  (iii) it shall go into effect when approved by a vote
of the Board and its  Independent  Directors  cast in person at a meeting called
for the  purpose  of  voting  on such  agreement;  and  (iv)  it  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

                                      6

<PAGE>


a vote of the Board and its  Independent  Directors  cast in person at a meeting
called for the purpose of voting on such continuance.

7. Effectiveness,  Continuation,  Termination and Amendment.  This Plan has been
approved by a vote of the Board and its Independent  Directors cast in person at
a meeting  called on  February  23, 1994 for the purpose of voting on this Plan,
and  replaces  the Fund's  Distribution  and Service  Plan and  Agreement  dated
October 25, 1993. Unless terminated as hereinafter  provided,  it shall continue
in effect year to year  thereafter or as the Board may otherwise  determine only
so long as such continuance is specifically approved at least annually by a vote
of the Board and its  Independent  Directors  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 without  approval of the
Class B Shareholders, in the manner described above, and all material amendments
must be approved by a vote of the Board and of the Independent  Directors.  This
Plan may be  terminated  at any time by vote of a  majority  of the  Independent
Directors or by the vote of the holders of a "majority"  (as defined in the 1940
Act) of the Fund's  outstanding  voting securities of the Class. In the event of
such  termination,  the  Board and its  Independent  Directors  shall  determine
whether  the  Distributor  is  entitled  to  payment  from the Fund of all Carry
Forward  Expenses and related costs properly  incurred in respect of Shares sold
prior to the  effective  date of such  termination,  and  whether the Fund shall
continue to make payment to the  Distributor  in the amount the  Distributor  is
entitled  to retain  under part (d) of Section 3 hereof,  until such time as the
Distributor  has been  reimbursed for all such amounts by the Fund, by retaining
CDSC payments, or by a combination of both.

1. AVERAGE ANNUAL TOTAL RETURNS FOR THE PERIODS ENDED 08/31/97:

   The formula for calculating average annual total return is as follows:

          1                              ERV n
   --------------- = n                  (---) - 1 = average annual total return
   number of years                        P

   Where:  ERV = ending redeemable value of a hypothetical $1,000 payment
                 made at the beginning of the period
           P   = hypothetical initial investment of $1,000

Class A Shares

Examples, assuming a maximum               Examples at NAV:

1. AVERAGE ANNUAL TOTAL RETURNS FOR THE PERIODS ENDED 08/31/97:

   The formula for calculating average annual total return is as follows:

           1                             ERV n
   --------------- = n                  (---) - 1 = average annual total return
   number of years                        P

   Where:  ERV = ending redeemable value of a hypothetical $1,000 payment
                 made at the beginning of the period

3. STANDARDIZED YIELD FOR THE 30-DAY PERIOD ENDED 08/31/97:

    The Fund's  standardized  yields are calculated using the following  formula
    set forth in the SEC rules:

                                        a - b          6
                         Yield =  2 { (--------  +  1 )  -  1 }
                                       cd or ce

   The symbols above represent the following factors:

     a = Dividends and interest earned during the 30-day period.
     b = Expenses accrued for the period (net of any expense
         reimbursements).
     c   = The average daily number of Fund shares outstanding during the 30-day
         period that were entitled to receive dividends.
     d   = The Fund's maximum  offering price (including sales charge) per share
         on the last day of the period.
     e   = The Fund's  net asset  value  (excluding  contingent  deferred  sales
         charge) per share on the last day of the period.

Class A Shares

Example, assuming a maximum sales charge of 4.75%:


           $386,450.85 - $ 43,215.65       6
        2{(-------------------------  +  1)  - 1}  = 4.53%
             6,922,027  x  $13.27


Class B Shares

Example at NAV:


           $ 50,122.89 - $ 15,035.24       6
        2{(-------------------------  +  1)  - 1}  = 3.74%
               898,902  x  $12.63

4. DIVIDEND YIELDS FOR THE PERIOD ENDED 08/31/97:

    The Fund's dividend yields are calculated using the following formula:

              Dividend Yield   =  { (a X 12} / b or c

    The symbols above represent the following factors:

   a = The last  dividend  earned  during the  period.  b = The  Fund's  maximum
   offering price (including sales charge)
       per share on dividend payble date.
   c   = The  Fund's  net asset  value  (excluding  sales  charge)  per share on
       dividend payable date.

Examples:

Class A Shares

  Dividend Yield
  at Maximum Offering     $.0611000 * 12 / $13.29 =  5.52%


  Dividend Yield
  at Net Asset Value      $.0611000 * 12 / $12.66 = 5.79%



Class B Shares

  Dividend Yield
  at Net Asset Value      $.0500580 * 12 / $12.65 = 4.75%

5. TAX-EQUIVALENT YIELDS FOR THE 30-DAY PERIOD ENDED 08/31/97:

   The Fund's tax-equivalent yields are calculated using the following formula:

              a / (1 - c) + b =  Tax-Equivalent Yield

   The symbols above represent the following factors:

   a = 30-day SEC yield of tax-exempt  security positions in the portfolio.  b =
   30-day SEC yield of taxable security positions in the portfolio. c = Combined
   stated tax rate (e.g., federal and state income tax rates
       for an individual in the 39.6% federal tax bracket filing singly).


Examples:


  Class A Shares         .0453 / (1 - .4522) +  0  = 8.27%


  Class B Shares         .0374 / (1 - .4522) +  0  = 6.83%



Combined Stated Tax Rate Formula:

              1 - {(1-d)(1-e)} = Combined Stated Tax Rate

  The symbols above represent the following factors:

  d   = Stated federal tax rate (e.g., federal income tax rate for an individual
      in the 39.6% federal tax bracket filing singly).
  e   = Stated  California  State tax rate (e.g., for an individual in the 39.6%
      federal and 9.30% state tax bracket filing singly).



   Example:   1 - {(1 - .3960)(1 - 0.0930)} = 45.22%
