registration  of Class A, B and C shares  of  Oppenheimer  Municipal  Bond  Fund
("Municipal Bond Fund") to be offered to the shareholders of Oppenheimer Insured

Shareholders  (the  "Meeting") to approve the  Reorganization  Agreement and the
transactions  contemplated thereby (the "Reorganization").  If shareholders vote
to approve the Reorganization and the Reorganization  Agreement,  the net assets
of Insured  Municipal  Fund will be acquired  by and in  exchange  for shares of
Municipal  Bond Fund.  The Meeting  will be held at the  offices of  Oppenheimer
Municipal Fund (the "Trust") at 6803 South Tucson Way, Englewood, Colorado 80112

Trust is soliciting  these  proxies on behalf of Insured  Municipal  Fund.  This

      If the shareholders vote to approve the  Reorganization  Agreement and the
Reorganization,  you will receive Class A shares of Municipal Bond Fund equal in
value to the value as of the  Valuation  Date of your  Class A shares of Insured

income exempt from federal  personal income taxes as is available from investing
in municipal  securities,  while  attempting to preserve  capital.  Under normal
market conditions,  Municipal Bond Fund attempts to invest 100% of its assets in
municipal  securities.  Municipal Bond Fund, as a matter of fundamental  policy,
invests at least 80% of its assets,  in  municipal  securities.  With respect to
below investment grade investments,  Municipal Bond Fund limits itself to 25% or
less of total assets.  Municipal  Bond Fund currently  emphasizes  investment in
municipal  securities  with  long-term  maturities  and may invest in  municipal
securities   subject  to  the  alternative   minimum  tax  (i.e.  AMT  municipal
securities).

                                   SYNOPSIS

      This is only a  summary  and is  qualified  in its  entirety  by the  more
detailed  information   contained  in  or  incorporated  by  reference  in  this
Prospectus  and Proxy  Statement and by the  Reorganization  Agreement  which is
attached as Exhibit A. Shareholders  should carefully review this Prospectus and
Proxy Statement and Reorganization Agreement in its entirety and, in particular,
the current  Prospectus of Municipal Bond Fund which accompanies this Prospectus
and Proxy Statement and is incorporated herein by reference.

On what Proposal am I being asked to vote?

      At a  meeting  held on  February  29,  2000,  the  Board  of  Trustees  of
Oppenheimer  Municipal  Fund on behalf of  Insured  Municipal  Fund  approved  a
reorganization transaction that will, if approved by shareholders, result in the
transfer of the net assets of Insured  Municipal Fund to Municipal Bond Fund, in
exchange  for an equal  value of shares of  Municipal  Bond Fund.  The shares of
Municipal  Bond  Fund  will  then  be  distributed  to  Insured  Municipal  Fund
shareholders  and  Insured  Municipal  Fund will be  liquidated.  (The  proposed
Reorganization  is referred to in this  Prospectus  and Proxy  Statement  as the
"Reorganization.")  As a result of the  Reorganization,  you will  cease to be a
shareholder of Insured Municipal Fund and will become a shareholder of Municipal
Bond Fund. This exchange will occur on the Closing Date of the Reorganization.

      This means your shares of Insured  Municipal Fund will be exchanged for an
equal value of shares of Municipal  Bond Fund. You will receive Class A, Class B
or Class C shares of  Municipal  Bond Fund equal in value to the value as of the
valuation  date of your  Class A,  Class B or Class C shares,  respectively,  of
Insured Municipal Fund. The shares you receive will be issued at net asset value
without a sales  charge or the payment of a  contingent  deferred  sales  charge
("CDSC")  although  if your  shares of Insured  Municipal  Fund are subject to a
CDSC,  your  Municipal  Bond Fund shares will continue to be subject to the CDSC
applicable to your shares. In calculating CDSC, the length of time for which you
held your Insured  Municipal  Fund shares will carry over to your Municipal Bond
Fund shares.

      For the reasons set forth in the "Reasons for the Reorganization" section,
the Board of Insured Municipal Fund has determined that the Reorganization is in
the best  interests of the  shareholders  of Insured  Municipal  Fund. The Board
concluded  that no  dilution in value would  result to  shareholders  of Insured
Municipal Fund as a result of the Reorganization.

                THE BOARD OF TRUSTEES RECOMMENDS THAT YOU VOTE
              TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION
                            AND THE REORGANIZATION

What are the general tax consequences of the Transaction?

      It is expected that  shareholders  of Insured  Municipal Fund who are U.S.
citizens will not recognize any gain or loss for federal income tax purposes, as
a result of the exchange of their shares for shares of Municipal  Bond Fund. You
should,  however,  consult your tax advisor regarding the effect, if any, of the
Reorganization  in light  of your  individual  circumstances.  You  should  also
consult  your tax advisor  about state and local tax  consequences.  For further
information  about the tax  consequences of the  Reorganization,  please see the
"Information  About  the  Transaction  - What  are the tax  consequences  of the
Reorganization?"

                    COMPARISONS OF SOME IMPORTANT FEATURES

How do the investment objectives and policies of the two Funds compare?

      Insured Municipal Fund is a series of Oppenheimer Municipal Fund, which is
a   mutual   fund  in  the   OppenheimerFunds   complex.   It  is   managed   by
OppenheimerFunds,  Inc.  (the  "Manager").  It  has  investment  objectives  and
policies which are substantially similar but not identical to those of Municipal
Bond Fund.  Insured  Municipal  Fund seeks a high level of current income exempt
from  federal  personal  income  taxes by  investing  in  municipal  securities.
Municipal  Bond Fund seeks maximum  current  income  exempt from federal  income
taxes by  investing  in  municipal  securities,  while  attempting  to  preserve
capital.

      In  seeking  their  investment  objectives,  Insured  Municipal  Fund  and
Municipal Bond Fund utilize a similar investing strategy and invest primarily in
municipal  securities.  Insured Municipal Fund, as a non-fundamental  investment
policy, invests at least 80% of its total assets in municipal securities, and at
least 65% of its  assets in insured  and  "pre-refunded"  municipal  securities.
Municipal Bond Fund, as a matter of fundamental policy,  invests at least 80% of
its assets in municipal securities.

      With respect to below investment grade investments, Insured Municipal Fund
limits such  investments to 10% or less of its total assets while Municipal Bond
Fund  limits  such  investments  to 25% or  less of  total  assets.  Both  Funds
currently emphasize investment in municipal securities with long-term maturities
and may invest in municipal  securities  subject to the alternative  minimum tax
(i.e. AMT municipal securities).

      As of March 31, 2000, the average credit quality of Insured Municipal Fund
was AAA and 83.01% of the portfolio's municipal securities were "insured." As of
March 31, 2000,  the average  credit  quality of Municipal  Bond Fund was A+ and
28.03% of the portfolio's  municipal  securities  were  "insured."  During 1999,
Insured Municipal Fund did not use any insurance protection  associated with its
municipal  securities.  To the best knowledge of the Manager,  Insured Municipal
Fund has never activated any municipal bond insurance coverage on its holdings.

      In  order  to  manage  interest  rate  risk  in  a  rising  interest  rate
environment, the Manager recently began selling some of Insured Municipal Fund's
longer  duration  bonds and  replaced  them with shorter  duration  instruments.
Consequently,  the income earned by Insured  Municipal  Fund has decreased  and,
effective April 11, 2000, the Board of Trustees of Insured Municipal Fund at the
request of Management  reduced Insured Municipal Fund's Class A dividend payment
from $0.0683 per share to $0.0661 per share.

Who manages the two Funds?

      The day-to-day  management of the business and affairs of each Fund is the
responsibility  of the Manager  under the  oversight  of each Fund's  respective
Board  of  Trustees.  Insured  Municipal  Fund is a series  fund of  Oppenheimer
Municipal Fund, an open-end registered management investment company,  which was
organized as a Massachusetts  business trust in 1986, and is registered with the
SEC. Insured Municipal Fund commenced operations on November 11, 1986. Municipal
Bond Fund was originally incorporated in Maryland in 1976 but was reorganized in
1987 as a  Massachusetts  business  trust,  and is also registered with the SEC.
Municipal Bond Fund is an open-end registered management investment company.

      The Manager, OppenheimerFunds, Inc., is located at Two World Trade Center,
New York, New York 10048, and acts as investment advisor to both Funds.

      Robert E.  Patterson,  a Senior  Vice  President  of the  Manager,  is the
portfolio  manager for Municipal  Bond Fund. He became the portfolio  manager on
November  18, 1985 and has been  employed by the Manager  since  November  1985.
Information  regarding Mr.  Patterson and his business  experience  for the last
five years is provided in the  accompanying  Prospectus  of Municipal  Bond Fund
under the section "How the Fund is Managed."

      Christian  D.  Smith,  a Senior  Vice  President  of the  Manager,  is the
portfolio  manager of Insured Municipal Fund. He became the portfolio manager on
November  1, 1999 and has been  employed by the Manager  since  September  1999.
Information  regarding Mr. Smith and his business  experience  for the last five
years is provided in the accompanying Prospectus of Insured Municipal Fund under
the section "How the Fund is Managed."

What  are the fees and  expenses  of each  Fund and  those  expected  after  the
Reorganization?

      Insured  Municipal  Fund and  Municipal  Bond Fund  each pay a variety  of
expenses directly for management of their assets,  administration,  distribution
of their shares and other  services.  Those  expenses are  subtracted  from each
Fund's  assets to calculate  the Fund's net asset value per share.  Shareholders
pay these expenses indirectly. Shareholders pay other expenses directly, such as
sales charges and account transaction charges. The following tables are provided
to help you  understand and compare the fees and expenses of investing in shares
of Insured  Municipal  Fund with the fees and expenses of investing in shares of
Municipal Bond Fund. The pro forma expenses of the surviving Municipal Bond Fund
show what the fees and expenses  are  expected to be after giving  effect to the
Reorganization.  All amounts  shown are a percentage of net assets of each class
of shares of the Funds.

Examples

      These  examples  below  are  intended  to help  you  compare  the  cost of
investing in each Fund and the proposed  surviving  Municipal  Bond Fund.  These
examples  assume an annual return for each class of 5%, the  operating  expenses
remain the same as described  above,  and  reinvestment  of your  dividends  and
distributions.

      Your actual costs may be higher or lower  because  expenses will vary over
time.  For each  $10,000  investment,  you  would  pay the  following  projected
expenses if you sold your shares after the number of years shown.

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

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

      Performance information for both Insured Municipal Fund and Municipal Bond
Fund is set forth in each Fund's  Prospectus  under the section "The Fund's Past
Performance." Municipal Bond Fund's Prospectus accompanies this Prospectus/Proxy
Statement and is incorporated by reference.

      The  financial   statements  of  Insured  Municipal  Fund  and  additional
information with respect to the Fund's  performance  during the past fiscal year
(and the most recent six month  semi-annual  period),  including a discussion of

How have the Funds performed?

      The following past performance information is set forth in each Prospectus
for each Fund: (i) a bar chart detailing  annual total returns of Class A shares
of each Fund as of December 31st for each of the full calendar  years since such
Fund's  inception;  and (ii) a table  detailing  how the  average  annual  total
returns of each Fund's  Class A, Class B and Class C shares  compare to those of
the Lehman  Brothers  Municipal  Bond Index,  a broad-based  market index.  Past
performance does not necessarily indicate how a fund will perform in the future.
      Average  annual total returns for the Funds for the periods ended June 30,
2000 are as follows:

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

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

Total returns include  changes in share price and  reinvestment of dividends and
capital gains distributions in a hypothetical  investment for the periods shown.
An explanation of the different  performance  calculations  is set forth in each
Fund's Prospectus and Statement of Additional  Information.  Each Fund's average
annual total return  includes the  applicable  sales charge for Class A, Class B
and Class C shares:  for Class A, the current  maximum  initial  sales charge of
4.75%; Class B, the contingent  deferred sales charges of 5% (1 year), and 2% (5
year);  and Class C, a  contingent  deferred  sales  charge of 1% if shares  are
redeemed within 12 months of purchase. Municipal Bond Fund's annual total return
also includes the applicable  sales charge for Class B shares of 1% (life of the
class).

      The graphs that  follow show the  performance  of a  hypothetical  $10,000
investment  in each  class of  shares  of  Insured  Municipal  Fund  held  until
September 30, 1999. In the case of Class A shares,  performance is measured over
a 10-year  period.  In the case of Class B shares,  performance is measured from
inception  of  the  class  on May 3,  1993.  In the  case  of  Class  C  shares,
performance  is measured  from  inception of the class on August 29,  1995.  The
Fund's performance reflects the deduction of the maximum initial sales charge on
Class A shares, the applicable  contingent  deferred sales charge on Class B and
Class  C  shares,   and   reinvestments  of  all  dividends  and  capital  gains
distributions.   Insured  Municipal  Fund's   performance  is  compared  to  the
performance of that of the Lehman  Brothers  Municipal Bond Index,  an unmanaged
index of a broad  range of  investment  grade  municipal  bonds  that is  widely
regarded as a measure of the  performance of the general  municipal bond market.
Index  performance  reflects the reinvestment of dividends but does not consider
the effect of capital gains or  transaction  costs,  and none of the data in the
graphs that follow shows the effect of taxes.  The Fund's  performance  reflects
the effects 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 index.

What are other key features of the Funds?

      The description of certain key features of the Funds below is supplemented
by each Fund's  Prospectus  and  Statement of Additional  Information  which are
incorporated herein by reference.

      Investment  Management  and Fees -  OppenheimerFunds,  Inc.,  manages  the
assets of both  Insured  Municipal  Fund and  Municipal  Bond Fund and makes the
investment  decisions for both Funds.  Both Funds obtain  investment  management
services from the Manager  according to the terms of management  agreements that
are substantially the same except for fee rates.

      Under its management agreement,  Insured Municipal Fund pays the Manager a
management  fee equal to an annual  rate of:  0.450% of the first $100  million,
0.400% of the next $150 million,  0.375% of the next $250 million, and 0.350% of
average annual net assets in excess of $500 million.  Insured  Municipal  Fund's
management  fee for the year ended  September 30, 1999, was 0.44% of the average
annual net assets for each class of shares.

      Under its  management  agreement,  Municipal  Bond Fund pays the Manager a
management  fee equal to an annual  rate of:  0.60% of the first  $200  million,
0.55% of the next $100  million,  0.50% of the next $200  million,  0.45% of the
next $250  million,  0.40% of the next $250  million  and 0.35% of  average  net
assets in excess of $1 billion.  Municipal  Bond Fund's  management  fee for the
year ended July 31,  1999,  was 0.52% of the average  annual net assets for each
class of shares.

      Effective upon the Closing of the Reorganization,  the management fee rate
for Municipal Bond Fund is expected to be 0.51%, based on assets of the Funds as
of March 31, 2000 which equalled  118,366,480 and 575,187,305 for Class A, Class
B and  Class C shares  of  Insured  Municipal  Fund  and  Municipal  Bond  Fund,
respectively.

      Transfer  Agency and  Custody  Services  -  OppenheimerFunds  Services,  a
division of the Manager,  acts as transfer and shareholder servicing agent on an
at-cost basis for both  Municipal  Bond Fund and Insured  Municipal Fund and for
certain  other  open-end  funds managed by the Manager and its  affiliates.  The
terms of the Transfer  Agency  Agreement  for both Funds are  substantially  the
same.

      Citibank, N.A., located at 399 Park Avenue, New York, New York, 10043 acts
as custodian of the securities and other assets of both Funds.

      Distribution   Services  -   OppenheimerFunds   Distributor,   Inc.   (the
"Distributor") acts as the principal underwriter in a continuous public offering
of shares of both  Funds,  but is not  obligated  to sell a  specific  number of
shares.  Both Funds also adopted a Service Plan and  Agreement  under Rule 12b-1
for their Class A shares that reimburses the  Distributor for providing  certain
shareholder  services  at an annual  rate up to 0.25% of  average  net assets of
Class A shares of the  Funds.  Both  Funds have also  adopted  Distribution  and
Service  Plans  under  Rule  12b-1  for  their  Class B and  Class C  shares  to
compensate the Distributor for services in connection with  distribution.  Under
these Plans,  the Funds pay the  Distributor an asset-based  charge at an annual
rate of 0.75% of net  assets on their  Class B and Class C shares,  whether  the
Distributor's  distribution  expenses  are more or less than the amounts paid by
the Fund under the Plan during the period. Both Funds also pay an annual service
fee of  0.25%  of net  assets  on  their  Class  B and  Class  C  shares  to the
Distributor.  The Distributor then uses these service fees to compensate dealers
for providing personal services and maintaining  shareholder accounts. The terms
of the Service  Plan and  Agreement  and the  Distribution  and Service Plan are
substantially the same for both Funds.

      For a detailed description of each Fund's  distribution-related  services,
see section entitled "Comparison of Investment  Objectives and Policies - How do
the Account Features and Shareholder Services for the Funds Compare?"

      Purchases,  Redemptions,  Exchanges and other Shareholder  Services - Both
Funds have the same  requirements and restrictions in connection with purchases,
redemptions and exchanges.  In addition, each Fund also offers the same level of
shareholder   services.   More   detailed   information   regarding   purchases,
redemptions,  exchanges  and  shareholder  services  can be  found  below in the
section  "Comparison of Investment  Objectives and Policies - How do the Account
Features and Shareholder Services for the Funds Compare?"

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

      For a  detailed  description  of  each  Fund's  policy  on  dividends  and
distribution,  see section  entitled  "Comparison  of Investment  Objectives and
Policies - How do the Account  Features and  Shareholder  Services for the Funds
Compare?"

What are the risks of an investment in the Municipal Bond Fund?

      As with most  investments,  investments in Municipal Bond Fund and Insured
Municipal Fund involve risks.  There can be no guarantee  against loss resulting
from an  investment in either Fund,  nor can there be any assurance  that either
Fund  will  achieve  its  investment  objective.  The risks  associated  with an
investment in each Fund are similar and include risks associated with tax-exempt
and other fixed income investments  generally,  such as interest rate and credit
risks.  There are,  however,  some  distinctions  in the investment  programs of
Municipal  Bond  Fund  and  Insured  Municipal  Fund.  Specifically,  there  are
differences in the variety of permitted  investments  and risks  associated with
such  investments,  and the percentage of investments  in  non-investment  grade
securities.

      For more information  about the risks of the Funds, see "What are the risk
factors associated with investments in the Funds?" under the heading "Comparison
of Investment Objectives and Policies."

                        REASONS FOR THE REORGANIZATION

      The Board of Trustees of the Trust,  on behalf of Insured  Municipal Fund,
recommended the  Reorganization  for purposes of combining the Insured Municipal
Fund with  Municipal  Bond Fund, a larger fund.  Because of the  relatively  low
demand  for  Insured  Municipal  Fund,  and  higher  operating  expenses  due to
continued net  redemptions,  the Manager  recommended  to the Board that Insured
Municipal  Funds'  assets  be  combined  with a larger  fund  that  has  similar
investment goals and policies.

      The Reorganization Agreement was presented to the Board of Trustees of the
Trust on behalf of Insured  Municipal  Fund at a meeting  held on  February  29,
2000.  At the  meeting,  the Board  questioned  management  about the  potential
benefits and costs to  shareholders of Insured  Municipal  Fund.  While deciding
whether to recommend approval of the  Reorganization to shareholders,  the Board
considered, among other things: the expense ratios of Insured Municipal Fund and
Municipal Bond Fund; the comparative investment performance of Insured Municipal
Fund  and  Municipal  Bond  Fund;   the  investment   objectives  and  policies,
restrictions and investments of Insured  Municipal Fund and Municipal Bond Fund;
the tax consequences of the  Reorganization;  and the significant  experience of
the Manager. The Board also noted that the Fund's arrangements for the purchase,
sale and/or exchange of shares are also  substantially  the same. The Board also
noted  that  each Fund will pay for its own  Reorganization  expenses  incurred,
including  the tax  opinion,  and  that the  Reorganization  is  expected  to be
tax-free to shareholders and the Funds.

      The Board  concluded that the  Reorganization  is in the best interests of
the shareholders of Insured  Municipal Fund and that no dilution would result to
shareholders   from  the   Reorganization.   It  then  decided  to  approve  the
Reorganization Agreement and to recommend that shareholders of Insured Municipal
Fund vote to approve  the  Reorganization.  As  required  by law,  the  Trustees
approving the  Reorganization  Agreement included a majority of the Trustees who
are not interested persons of Insured Municipal Fund.

      The Board's  conclusion  was based on a number of factors,  including that
the Reorganization would permit shareholders to pursue their investment goals in
a larger fund. A larger fund should have an enhanced ability to effect portfolio
transactions  on  more  favorable  terms  and  should  have  greater  investment
flexibility.  A fund with higher aggregate net assets may also be able to reduce
certain costs and  expenses.  This may result in lower  overall  expense  ratios
through the  spreading  of fixed costs of fund  operations  over a larger  asset
base.  However,  variable  expenses that are based on the value of assets or the
number of shareholder  accounts,  such as custody and transfer agent fees, would
be largely unaffected by the Reorganization.  In addition,  information provided
to the Board  indicated that total  operating  expenses of Class A shares of the
surviving  Municipal  Bond Fund will  decrease  slightly  as compared to Insured
Municipal Fund, and the total operating  expenses of Municipal Bond Fund's Class
B and Class C shares will remain the same.

      The Board of Municipal Bond Fund also determined that the Reorganization
was in the best interests of Municipal Bond Fund and its shareholders and
that no dilution would result to shareholders.  Municipal Bond Fund
shareholders do not vote on the Reorganization.
      For the reasons discussed above, the Board, on behalf of Insured Municipal
Fund,  recommends  that  you  vote  FOR  the  Reorganization  Agreement.  If the
shareholders  of  Insured  Municipal  Fund  do not  approve  the  Reorganization
Agreement,  the Board will consider other possible courses of action for Insured
Municipal Fund, including dissolution and liquidation.

                     INFORMATION ABOUT THE REORGANIZATION

      This is only a summary of the  Reorganization  Agreement.  You should read
the actual form of Reorganization Agreement. It is attached as Exhibit A.

How Will the Reorganization be Carried Out?

      If the shareholders of Insured  Municipal Fund approve the  Reorganization
Agreement,  the  Reorganization  will take place after  various  conditions  are
satisfied by Insured Municipal Fund and Municipal Bond Fund,  including delivery
of certain  documents.  The closing date is presently  scheduled for  _________,
2000 and the  valuation  date is presently  scheduled for  __________,  2000. If
shareholders  of  Insured  Municipal  Fund  do not  approve  the  Reorganization
Agreement, the Reorganization will not take place.

      If  shareholders  of Insured  Municipal  Fund  approve the  Reorganization
Agreement,   Insured   Municipal  Fund  will  deliver  to  Municipal  Bond  Fund
substantially  all of its  assets on the  closing  date.  In  exchange,  Insured
Municipal  Fund,  will receive Class A, Class B and Class C Municipal  Bond Fund
shares that have a value equal to the dollar  value of the assets  delivered  by
Insured Municipal Fund to Municipal Bond Fund.  Insured Municipal Fund will then
be liquidated and its outstanding  shares will be cancelled.  The stock transfer
books of  Insured  Municipal  Fund  will be  permanently  closed at the close of
business on the valuation date. Only redemption requests received in proper form
on or before the close of business on the  valuation  date shall be fulfilled by
Insured  Municipal Fund.  Redemption  requests  received after that time will be
considered requests to redeem shares of Municipal Bond Fund.

      Shareholders of Insured  Municipal Fund who vote their Class A, Class B or
Class C shares  in favor of the  Reorganization  will be  electing  in effect to
redeem  their  shares  of  Insured  Municipal  Fund at net  asset  value  on the
Valuation Date, after  subtracting a Cash Reserve,  and reinvest the proceeds in
Class A, Class B or Class C shares of  Municipal  Bond Fund at net asset  value.
The Cash  Reserve is that  amount  retained by Insured  Municipal  Fund which is
deemed  sufficient in the  discretion of the Board for the payment of the Fund's
outstanding  debts  and  expenses  of  liquidation.   If  the  Cash  Reserve  is
insufficient to satisfy any of Insured Municipal Fund's liabilities, the Manager
will assume  responsibility for any such unsatisfied  liability.  Municipal Bond
Fund is not  assuming  any debts of  Insured  Municipal  Fund  except  debts for
unsettled  securities  transactions  and  outstanding  dividend  and  redemption
checks.  Insured Municipal Fund will recognize capital gain or loss on any sales
made prior to the Reorganization.

      Under the  Reorganization  Agreement,  within one year  after the  Closing
Date,  Insured Municipal Fund shall: (a) either pay or make provision for all of
its debts and taxes;  and (b) either (i)  transfer any  remaining  amount of the
Cash Reserve to Municipal  Bond Fund, if such  remaining  amount is not material
(as defined below) or (ii) distribute such remaining  amount to the shareholders
of Insured  Municipal Fund who were such on the Valuation Date. If the remaining
Cash Reserve is distributed to former Insured Municipal Fund shareholders,  such
distribution  would be  considered  a return of capital for  federal  income tax
purposes,  reducing the tax basis of the shares received in the  Reorganization,
should it be approved.  Such remaining  amount shall be deemed to be material if
the amount to be  distributed,  after  deducting the  estimated  expenses of the
distribution,  equals or  exceeds  one cent per share of the  number of  Insured
Municipal Fund shares  outstanding on the Valuation Date.  Within one year after
the Closing Date, Insured Municipal Fund will complete its liquidation.

      Under the  Reorganization  Agreement,  either  Insured  Municipal  Fund or
Municipal  Bond Fund may  abandon and  terminate  the  Reorganization  Agreement
without liability to the other party. See Exhibit A attached hereto.

      To the  extent  permitted  by law,  the  Funds  may  agree  to  amend  the
Reorganization  Agreement without shareholder  approval.  They may also agree to
terminate  and abandon the  Reorganization  at any time before or, to the extent
permitted by law, after the approval of shareholders of Insured Municipal Fund.

Who Will Pay the Expenses of the Reorganization?

      The Funds will bear the cost of the tax  opinion.  Any  documents  such as
existing prospectuses or annual reports that are included in the proxy statement
mailing or at a  shareholder's  request  will be a cost of the Fund  issuing the
document.  Any other  out-of-pocket  expenses,  including legal,  accounting and
transfer  agent  expenses  associated  with the  Reorganization  will be paid by
Insured  Municipal  Fund and  Municipal  Bond  Fund,  respectively,  in  amounts
incurred by each.  Management  estimates that such expenses  associated with the
Reorganization  to be borne by Insured Municipal Fund should not exceed $41,000.
Liabilities  as of the date of the transfer of assets will consist  primarily of
accrued  but  unpaid  normal  operating  expenses  of  Insured  Municipal  Fund,
excluding the cost of any portfolio securities purchased but not yet settled and
outstanding shareholder redemption and dividend checks.

What are the Tax Consequences of the Reorganization?

      The Reorganization is intended to qualify as a tax-free reorganization for
federal income tax purposes under Section 368(a)(1) of the Internal Revenue Code
of 1986, as amended.  Based on certain assumptions and representations  received
from the Insured  Municipal  Fund, and Municipal Bond Fund, it is expected to be
the opinion of KPMG LLP, tax advisor to the Funds,  that shareholders of Insured
Municipal  Fund  will not  recognize  any gain or loss for  federal  income  tax
purposes  as a result of the  exchange of their  shares for shares of  Municipal
Bond Fund and that  shareholders  of Municipal  Bond Fund will not recognize any
gain or loss upon receipt of Insured Municipal Funds' assets.  Neither Fund will
recognize gain as a result of the Reorganization.

      Immediately prior to the Valuation Date, Insured Municipal Fund will pay a
dividend(s)  which will have the  effect of  distributing  to Insured  Municipal
Fund's  shareholders all of Insured Municipal Fund's  investment  company income
for taxable  years  ending on or prior to the  Closing  Date  (computed  without
regard to any deduction for dividends  paid) and all of its net capital gain, if
any,  realized in taxable  years  ending on or prior to the Closing  Date (after
reduction for any available capital loss carry-forward).  Taxable dividends will
be included in the taxable income of Insured  Municipal  Fund's  shareholders as
ordinary income and capital gain, respectively.

      You will  continue to be  responsible  for tracking the purchase  cost and
holding period of your shares and should consult your tax advisor  regarding the
effect, if any, of the Reorganization in light of your individual circumstances.
You should  also  consult  your tax  advisor as to state and local and other tax
consequences, if any, of the Reorganization because this discussion only relates
to federal income tax consequences.

What should I know about Class A, Class B and Class C shares of  Municipal  Bond
Fund?

      The rights of shareholders of both Funds are substantially the same. Class
A,  Class B and Class C shares of  Municipal  Bond Fund will be  distributed  to
shareholders   of  Class  A,  Class  B  and  Class  C  Insured   Municipal  Fund
shareholders,  respectively,  in connection with the Reorganization.  Each share
will be fully paid and  nonassessable  when issued  with no  personal  liability
attaching to the ownership thereof, will have no preemptive or conversion rights
and will be  transferable  on the books of  Municipal  Bond Fund.  The shares of
Municipal  Bond  Fund  will be  recorded  electronically  in each  shareholder's
account.  Municipal Bond Fund will then send a confirmation to each shareholder.
As  described  in its  prospectus,  Municipal  Bond Fund  does not  issue  share
certificates for its Class B and Class C shares.  Former Class A shareholders of
Insured Municipal Fund who wish to have certificates  representing  their shares
of  Municipal  Bond  Fund must make a written  request  to the  Transfer  Agent.
Shareholders of Insured Municipal Fund holding  certificates  representing their
shares will not be required to surrender  their  certificates in connection with
the  reorganization.  However,  former Class A shareholders of Insured Municipal
Fund whose shares are represented by outstanding share  certificates will not be
allowed to redeem shares of Municipal Bond Fund until the certificates have been
returned.

      Like Insured  Municipal Fund,  Municipal Bond Fund does not routinely hold
annual shareholder  meetings.  Municipal Bond Fund and Insured Municipal Fund do
not have  cumulative  voting  rights.  Insured  Municipal  Fund,  as a series of
Oppenheimer   Municipal   Fund,   and  Municipal  Bond  Fund  are  organized  as
Massachusetts  business  trusts.  Under certain  circumstances,  shareholders of
either  Fund  may  be  held  personally  liable  as  partners  for  such  Fund's
obligations,  however,  under the  Declaration  of Trust  governing  each of the
Funds, such a shareholder is entitled to certain  indemnification rights and the
risk  of a  shareholder  incurring  any  such  loss  is  limited  to the  remote
circumstances in which a Fund is unable to meet its obligations.

      What  are  the   capitalizations   of  the  Funds   and  what   might  the
capitalization be after the Reorganization?

      The following table sets forth the  capitalization  (unaudited) of Insured
Municipal  Fund and Municipal  Bond Fund and  indicates  the pro forma  combined
capitalization  as of March 31, 2000 as if the  Reorganization  had  occurred on
that date.

               COMPARISON OF INVESTMENT OBJECTIVES AND POLICIES

      This section  describes key investment  policies of Insured Municipal Fund
and  Municipal  Bond  Fund,  and  certain  noteworthy  differences  between  the
investment  objectives and policies of the two Funds. For a complete description
of  Municipal  Bond  Fund's  investment  policies  and risks  please  review its
prospectus  dated November 19, 1999,  which  accompanies  this  Prospectus/Proxy
Statement as Exhibit A.

Are there any  significant  differences  between the  investment  objectives and
strategies of the two Funds?

      Information  about  Insured  Municipal  Fund and  Municipal  Bond  Fund is
presented  below.  In  considering   whether  to  approve  the   Reorganization,
shareholders  of Insured  Municipal  Fund should  consider  the  differences  in
investment objectives,  policies and risks of the Funds.  Additional information
about  Municipal  Bond Fund is set forth in its  Prospectus,  accompanying  this
Prospectus/Proxy  Statement and incorporated herein by reference, and additional
information about both Funds is set forth in documents that may be obtained upon
request of the  transfer  agent or upon  review at the  offices of the SEC.  See
"Information about Insured Municipal Fund" and "Information about Municipal Bond
Fund"

      Insured Municipal Fund's  investment  objective is to seek a high level of
current  income  exempt from  federal  income  taxes by  investing  in municipal
securities.  Municipal  Bond  Fund's  investment  objective  is to seek  maximum
current  interest  income  exempt from  federal  income  taxes by  investing  in
municipal  securities,  while  attempting to preserve  capital.  The  investment
policies  of  the  Funds  differ   slightly.   Insured   Municipal  Fund,  as  a
non-fundamental  investment policy,  invests at least 80% of its total assets in
municipal   securities   and  at  least  65%  of  its  assets  in  insured   and
"pre-refunded"  municipal  securities.  Municipal  Bond  Fund,  as a  matter  of
fundamental policy,  invests at least 80% of its assets in municipal securities.
With respect to below  investment  grade  investments,  Insured  Municipal  Fund
limits such  investments to 10% or less of its total assets while Municipal Bond
Fund  limits  itself  to 25% or less  of  total  assets.  Both  Funds  currently
emphasize  investment in municipal  securities with long-term maturities and may
invest in municipal  securities subject to the alternative minimum tax (i.e. AMT
municipal securities).

How do the investment policies of the two Funds compare?

      Municipal  Securities.  The municipal securities that both Funds invest in
primarily include municipal bonds (which are long-term  obligations),  municipal
notes (short-term  obligations),  and interests in municipal leases.  Both Funds
invest  mainly in municipal  securities.  Municipal  securities  are  securities
issued by the  governments  of the District of Columbia and other states as well
as their political  subdivisions,  authorities,  instrumentalities and agencies,
and securities  issued by any  commonwealths,  territories or possessions of the
United States, or their respective  agencies,  instrumentalities or authorities,
if the interest paid on the security is not subject to federal  personal  income
tax (in the  opinion of bond  counsel to the issuer at the time the  security is
issued).

      The Funds can buy  municipal  securities  that are "general  obligations,"
secured by the  issuer's  pledge of its full faith,  credit and taxing power for
the  payment  of  principal  and  interest.  The  Funds  can also  buy  "revenue
obligations,"  payable only from the revenues derived from a particular facility
or class of facilities,  or a specific excise tax or other revenue source.  Some
revenue  obligations are private  activity bonds that pay interest that may be a
tax preference item for investors subject to alternative minimum tax.

      Insured Municipal Securities.  Insured Municipal Fund invests at least 65%
of its assets in "insured  municipal  securities."  These securities include (1)
securities   that  have  an  insurance   policy  covering  the  payment  of  all
installments  of interest  and  repayment of  principal  and (2)  "pre-refunded"
municipal  securities.  Although  insurance  reduces  the  effects  of  risks of
default, insurance on municipal securities that Insured Municipal Fund buys does
not  guarantee  or  insure  the  market  value of those  securities  or  Insured
Municipal  Fund's share prices.  If an issuer  defaults on an insured  municipal
security,  the payment of the claim under the  insurance  policy  depends on the
claims-paying ability of the insurance company.

      In a  "pre-refunding"  the issuer of a municipal  security issues a second
bond to raise  cash to pay off the first  bond at its call  date or  dates.  The
proceeds of the second bond are invested in U.S. Treasury securities that mature
on the  call  date  as  security  for the  payment.  Because  of the  collateral
arrangement,  these bonds  typically are rated in the highest rating category of
national rating  organizations  and are considered by Insured  Municipal Fund to
have credit protection equivalent to that of insured securities.  However, these
securities  also typically  offer a lower interest rate than the rate prevailing
in the market for comparable issues that do not have collateral arrangements.

      Ratings  of  Municipal  Securities  the Funds Buy.  Most of the  municipal
securities  both  Funds  buy are  "investment-grade"  at the  time of  purchase.
Insured  Municipal  Fund and Municipal Bond Fund do not invest more than 10% and
25%,  respectively,  of their total assets in municipal  securities  that at the
time of purchase are not  investment-grade.  "Investment-grade"  securities  are
those rated within the four highest  rating  categories  of Moody's,  Standard &
Poor's,   Fitch  or  Duff  &  Phelps  or  other  nationally   recognized  rating
organizations,  or (if unrated)  judged by the Manager to be comparable to rated
investment-grade securities.

      The   Manager   may   rely  to  some   extent   on   credit   ratings   by
nationally-recognized  rating  organizations  in  evaluating  the credit risk of
securities  selected for either Fund's portfolio.  It also uses its own research
and analysis.  Many factors affect an issuer's  ability to make timely payments,
and the credit risks of a particular security may change over time.

      If the  securities  are not rated,  the Manager  will use its  judgment to
assign a rating to a security  comparable  to that of a rating  agency.  Insured
Municipal Fund limits its  investments  in unrated  securities to 10% or less of
its total assets while  Municipal  Bond Fund limits itself to 25% or less of its
total assets in such  securities.  If the rating of a security is reduced  after
either Fund buys it, that Fund is not required  automatically to dispose of that
security.  However,  the Manager will  evaluate  those  securities  to determine
whether to keep them in the Fund's portfolio.

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

      Municipal Lease Obligations.  Municipal leases are used by state and local
governments to obtain funds to acquire land, equipment or facilities. Both Funds
can invest in  certificates  of  participation  that  represent a  proportionate
interest in payments made under  municipal  lease  obligations.  Most  municipal
leases, while secured by the leased property, are not general obligations of the
issuing municipality. They often contain "non-appropriation" clauses under which
the municipal government has no obligation to make lease or installment payments
in  future  years  unless  money  is  appropriated  on a  yearly  basis.  If the
government  stops making  payments or  transfers  its payment  obligations  to a
private entity, the obligation could lose value or become taxable.

      Other Investment Strategies. To seek their objectives,  the Funds can also
use the investment  techniques and strategies  described  below. The Funds might
not always use all of them.  These  techniques  have certain risks although some
are designed to help reduce overall investment or market risks.

o  Floating  Rate/Variable  Rate  Obligations.  Some municipal  securities  have
   variable or floating interest rates.  Variable rates are adjustable at stated
   periodic intervals.  Floating rates are automatically adjusted according to a
   specified  market rate for such  investments,  such as the  percentage of the
   prime rate of a bank, or the 91-day U.S. Treasury Bill rate.

   Certain  variable rate bonds known as "inverse  floaters" pay interest  rates
   that move in the opposite direction of yields on short-term bonds in response
   to market  changes.  As interest rates rise,  inverse  floaters  produce less
   current income, and their market value can become volatile.  Inverse floaters
   are a form of  derivative  investment.  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 Funds when
   the Funds have invested in inverse floaters that expose the Funds to the risk
   of short-term  interest  rate  fluctuations.  "Embedded"  caps can be used to
   hedge a portion  of the  Funds'  exposure  to  rising  interest  rates.  When
   interest rates exceed a  pre-determined  rate,  the cap generates  additional
   cash flows that offset the decline in interest rates on the inverse  floater,
   and the  hedge is  successful.  However,  the  Funds  bear  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.  Neither  Fund can invest more than 20% of its total
   assets in inverse floaters.

o  Other Derivatives. Both Funds can also invest in other derivative investments
   that pay interest that depends on the change in value of an underlying asset,
   interest  rate or index.  Examples  are hedging  instruments,  interest  rate
   swaps, municipal bond indices or swap indices.

   Derivatives  have risks. If the issuer of the derivative  investment does not
   pay the amount due, the Fund can lose money on the investment. The underlying
   security or  investment on which a derivative  is based,  and the  derivative
   itself,  may not perform  the way the Manager  expected it to. As a result of
   these  risks  the Fund  could  realize  less  principal  or  income  from the
   investment than expected or its hedge might be unsuccessful. As a result, the
   Fund's share prices could fall.  Certain  derivative  investments held by the
   Fund might be illiquid.

   Hedging. Both Funds can buy and sell futures contracts, put and call options,
   and enter into  interest rate swap  agreements.  These are all referred to as
   "hedging instruments." Neither Fund may use hedging for speculative purposes.
   Currently,  neither Fund uses hedging extensively.  Both Funds have limits on
   their use of hedging  instruments and are not required to use them in seeking
   their objective.

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

   Interest  rate swaps are subject to credit risks (if the other party fails to
   meet its  obligations)  and also to interest  rate risks.  The Funds could be
   obligated to pay more under their swap  agreements  than they  receive  under
   them,  as a result of  interest  rate  changes.  The Funds may not enter into
   swaps with respect to more than 25% of its total assets.

o  When-Issued  and  Delayed-Delivery  Transactions.  Both  Funds  may  purchase
   municipal  securities on a "when-issued"  basis and may purchase or sell such
   securities  on  a   "delayed-delivery"   basis.   Between  the  purchase  and
   settlement,  no payment is made for the security  and no interest  accrues to
   the buyer  from the  investment.  There is a risk of loss to the Funds if the
   value of the security declines prior to the settlement date.

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

o     Illiquid and Restricted Securities.  Investments may be illiquid because
   they do not have an active trading market, making it difficult to value
   them or dispose of them promptly at an acceptable price.  Neither Fund will
   invest more than 15% of its net assets in illiquid securities.  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.  Certain restricted securities that are eligible
   for resale to qualified institutional buyers may not be subject to that
   limit.  The Manager monitors holdings of illiquid securities on an ongoing
   basis to determine whether to sell any holdings to maintain adequate
   liquidity.  Municipal Bond Fund cannot buy securities that have a
   restriction on resale.

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

o     Loans of Portfolio Securities.  Both Funds can lend their portfolio
   securities to brokers, dealers and other financial institutions.  A Fund
   might do so to raise cash for liquidity purposes.  These loans are limited
   to not more than 5% of the value of the Insured Municipal Fund's total
   assets and not more than 25% of the value of Municipal Bond Fund's total
   assets.  There are risks in connection with securities lending.  The Fund
   might experience a delay in receiving additional collateral to secure a
   loan, or a delay in recovery of the loaned securities.  Neither Fund
   presently intends to engage in loans of securities that will exceed 5% of
   the value of that Fund's total assets.  Income from securities loans does
   not constitute exempt-interest income for the purpose of paying tax-exempt
   dividends.

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

   When it lends  securities,  a Fund receives amounts equal to the dividends or
   interest  on the  loaned  securities.  It  also  receives  one or more of (a)
   negotiated loan fees, (b) interest on securities used as collateral,  and (c)
   interest on short-term  debt securities  purchased with the loan  collateral.
   Either type of interest may be shared with the borrower or others. A Fund can
   pay  reasonable  finder's,  administrative  or other fees in connection  with
   these loans.  The terms of the Fund's loans must meet applicable  tests under
   the  Internal  Revenue  Code  and  must  permit  a Fund to  reacquire  loaned
   securities on five days' notice or in time to vote on any important matter.

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

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

o     Repurchase Agreements.  Both Funds can acquire securities subject to
   repurchase agreements.  They may do so for liquidity purposes to meet
   anticipated redemptions of Fund shares, or pending the investment of the
   proceeds from sales of Fund shares, or pending the settlement of portfolio
   securities transactions.  In a repurchase transaction, the Fund acquires a
   security from, and simultaneously resells it to an approved vendor for
   delivery on an agreed upon future date.  The resale price exceeds the
   purchase price by an amount that reflects an agreed-upon interest rate
   effective for the period during which the repurchase agreement is in
   effect.

   Repurchase  agreements having a maturity beyond seven days are subject to the
   Funds'  limits  on  holding  illiquid  investments.  There is no limit on the
   amount of Municipal  Bond Fund's net assets that may be subject to repurchase
   agreements of seven days or less.  Insured Municipal Fund will not enter into
   transactions that will cause more than 25% of its net assets to be subject to
   repurchase  agreements.  Because income earned on repurchase  transactions is
   not  tax-exempt,  under normal market  conditions  the Funds will limit their
   repurchase  transactions  to 20% of their  total  assets.  That  limit may be
   exceeded  if the Funds  use  repurchase  agreements  as  temporary  defensive
   investments.

What are the fundamental investment restrictions of the Funds?

      Both  Insured   Municipal  Fund  and  Municipal  Bond  Fund  have  certain
additional   investment   restrictions  that,  together  with  their  investment
objectives are fundamental  policies,  changeable only by shareholder  approval.
Generally, these investment restrictions are similar between the Funds. They are
discussed below. Fundamental policies govern the Funds' activities and cannot be
changed without shareholder approval.

o  Neither Fund can lend money except in connection with the acquisition of debt
   securities and repurchase  agreements as permitted by its investment policies
   and  restrictions.  Both Funds can also make loans of  portfolio  securities,
   subject to the  restrictions  listed in each Funds'  Statement of  Additional
   Information and summarized above.

o  Neither  Fund can  concentrate  its  investments  to the extent of 25% of its
   total  assets in any  industry.  However,  there is no  limitation  as to the
   Fund's  investments in municipal  securities or in obligations  issued by the
   U.S. Government and its agencies or instrumentalities.

o  Municipal  Bond  Fund  cannot  invest  in any  other  securities  other  than
   municipal securities, temporary defensive investments, repurchase agreements,
   covered calls, private activity municipal securities and hedging instruments.

o  Insured  Municipal  Fund  cannot  invest in  interests  in oil,  gas or other
   mineral exploration or development programs.

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

o  Municipal  Bond  Fund  cannot  invest  more than 5% of the value of its total
   assets in the  securities  of any one  issuer.  Municipal  Bond  Fund  cannot
   acquire more than 10% of the total value of all outstanding securities of any
   one issuer.  In both cases,  this restriction does not apply to securities of
   the U.S. Government or its agencies or instrumentalities.

o  Neither Fund can invest in real estate.  However,  the Funds are permitted to
   invest in municipal securities or other permissible securities or instruments
   secured by real estate or interests in real estate.

o  Neither Fund can purchase securities on margin. However, they can make margin
   deposits  when using  hedging  instruments  permitted  by any of their  other
   policies.  Insured Municipal Fund can invest in options,  futures, options on
   futures and similar instruments. Additionally, Municipal Bond Fund may obtain
   such short-term  credits that may be necessary for the clearance of purchases
   and sales of securities.

o     Neither Fund can sell securities short.

o  Insured  Municipal  Fund  cannot  invest  in  companies  for the  purpose  of
   acquiring control or management of those companies.
o  Neither  Fund can  underwrite  securities  of other  companies.  A  permitted
   exception  for  Insured  Municipal  Fund  is in case  it is  deemed  to be an
   underwriter  under the  Securities  Act of 1933 when reselling any securities
   held in its own portfolio.

o  Municipal  Bond  Fund  cannot  invest  in  securities  that  are  subject  to
   restrictions on resale.

o  Neither Fund can invest in or hold  securities  of any issuer if officers and
   directors or trustees of the funds or the Manager  individually  beneficially
   own more than 1/2 of 1% of the  securities  of that issuer and  together  own
   more than 5% of the securities of that issuer.

o  Insured  Municipal  Fund cannot invest in securities of any other  investment
   companies, except if they are acquired as part of a merger,  consolidation or
   other  acquisition.  Municipal  Bond Fund cannot  invest in securities of any
   other  investment  company,  except in connection  with a merger with another
   investment company.

o     Insured Municipal Fund cannot borrow money, except from banks for
   temporary purposes in amounts not in excess of 5% of the value of the
   Fund's assets.  No assets of the Fund may be pledged, mortgaged or
   hypothecated except to secure a borrowing, and in that case no more than
   10% of the Fund's total assets may be pledged, mortgaged or hypothecated.
   Borrowings may not be made for leverage, but only for liquidity purposes to
   satisfy redemption requests when the liquidation of portfolio securities is
   considered inconvenient or disadvantageous.  However, the Fund can enter
   into when-issued and delayed-delivery transactions.

o  Municipal  Bond Fund cannot borrow money in excess of 10% of the value of its
   total assets.  The Fund may borrow only from banks as a temporary measure for
   extraordinary  or emergency  purposes,  and not for the purpose of leveraging
   its investments. No assets of the Fund may be pledged, mortgaged or otherwise
   encumbered,  transferred  or assigned to secure a debt.  However,  the use of
   escrow  or  other   collateral   arrangements   in  connection  with  hedging
   instruments is permitted.

o     Neither Fund can issue "senior securities," (this is not a fundamental
   policy for Municipal Bond Fund but it will not be changed without the
   approval of shareholders) but this does not prohibit certain investment
   activities for which assets of the Funds are designated as segregated, or
   margin, collateral or escrow arrangements are established, to cover the
   related obligations.  Examples of those activities include borrowing money,
   reverse repurchase agreements, delayed-delivery and when-issued
   arrangements for portfolio securities transactions, and contracts to buy or
   sell derivatives, hedging instruments, options or futures.

What are the risk factors associated with investments in the Funds?

      Like all  investments,  an investment in both of the Funds  involves risk.
There is no assurance that the Funds will meet their investment objectives.  The
achievement of the Funds' goals depends upon market conditions,  generally,  and
on the portfolio managers' analytical and portfolio  management skills.  Insured
Municipal  Fund  invests  at  least  65%  of its  assets  in  insured  municipal
securities. Otherwise, the risks of the Funds are basically the same as those of
other  investments in municipal  securities and other fixed income securities of
similar quality.

      Interest  Rate Risk.  Changes in  interest  rates will affect the value of
each Fund's portfolio and its share prices.  Interest rate risk is the risk that
changes  in  interest  rates  can  reduce  the  value of a  security.  Municipal
securities  are  subject  to changes in value  when  prevailing  interest  rates
change.  When  interest  rates  fall,  the  values of  already-issued  municipal
securities   generally   rise.   When  interest   rates  rise,   the  values  of
already-issued  municipal  securities generally fall and the bonds may sell at a
discount  from  their face  amount.  The  magnitude  of these  price  changes is
generally  greater  for bonds with  longer  maturities  or  duration.  The Funds
currently focus on longer term securities to seek higher income.  Therefore, its
share prices may fluctuate more when interest rates change.

      Income Risk.  Income Risk is the risk that a Fund's  income will  decrease
due to falling interest rates. Since a Fund can only distribute what it earns, a
Fund's distributions to its shareholders may decline when interest rates fall.

      Credit Risk.  Municipal securities are debt securities that are subject to
credit  risk.  Credit risk is the risk that the issuer of a  municipal  security
might not make  interest and  principal  payments on the security as they become
due. If the issuer fails to pay  interest,  the Fund's  income might be reduced,
and if the issuer fails to repay  principal,  the value of that  security and of
the Fund's shares may be reduced.  A Fund may also suffer if an issuer's ability
to make payments of interest or principal,  or likelihood of payment of interest
or principal is perceived to decline.  Insured Municipal Fund and Municipal Bond
Fund may each invest as much as 10% and 25%,  respectively,  of their  assets in
municipal  securities below  investment  grade to seek higher income.  Municipal
Bond  Fund's  credit  risks  are  greater  than  those  of  funds  that buy only
investment-grade  bonds and potentially greater than the credit risks associated
with  Insured  Municipal  Fund.  Currently,  neither  Fund is  invested in below
investment grade  securities.  Insured  Municipal Fund's  investments in insured
municipal  securities help reduce some of the possible effects of credit risk to
the Fund.  To help  reduce  credit  risk,  Insured  Municipal  Fund  focuses  on
investment-grade  securities.  Credit  ratings are not guarantees of an issuer's
timely  payment of  obligations  and a downgrade or other  adverse news about an
issuer can reduce a security's market value.

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

      If the issuer of the  derivative  investment  does not pay the amount due,
the Funds can lose money on their investment.  Also, the underlying  security or
investment on which the derivative is based,  and the derivative  itself,  might
not perform the way the Manager  expected it to perform.  If that  happens,  the
Funds will get less income than expected,  or their hedge might be unsuccessful,
and their  share  prices  could  fall.  The Funds  have  limits on the amount of
particular types of derivatives they can hold.  However,  using  derivatives can
increase the  volatility of the Funds' share  prices.  Some  derivatives  may be
illiquid,  making  it  difficult  for the  Funds  to  sell  them  quickly  at an
acceptable price.

      Risks of Lower-Grade  Securities.  Insured Municipal Fund may invest up to
10% of its total  assets  and  Municipal  Bond Fund may  invest up to 25% of its
total assets in lower grade securities. These securities may have a higher yield
than securities rated in the higher rating  categories.  In addition to having a
greater risk of default  than  higher-grade  securities,  there may be less of a
market  for  these  securities.  As a result  they may be  harder  to sell at an
acceptable  price.  The additional  risks mean that the Fund may not receive the
anticipated  level of income  from  these  securities,  and the Fund's net asset
value may be affected by declines in the value of lower-grade securities.

How do the Account Features and Shareholder Services for the Funds Compare?

      Investment  Management - Pursuant to each investment  advisory  agreement,
the Manager  acts as the  investment  advisor for the Funds and  supervises  the
investment program of the Funds. The investment  advisory  agreements state that
the  Manager  will  provide  administrative  services  for the Funds,  including
compilation  and  maintenance  of  records,  preparation  and  filing of reports
required  by  the  SEC,  reports  to  shareholders,  and  composition  of  proxy
statements and registration  statements required by Federal and state securities
laws.  Further,  the Manager has agreed to furnish the Funds with office  space,
facilities  and  equipment and arrange for its employees to serve as officers of
the Funds.

      Expenses not expressly  assumed by the Manager under each Fund's  advisory
agreement or by the Distributor  under the General  Distributor's  Agreement are
paid by the Funds. The investment  advisory agreements list examples of expenses
paid by the Funds,  the major  categories  of which relate to  interest,  taxes,
brokerage  commissions,  fees to certain  Directors,  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.

      Both investment  advisory  agreements state 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 investment  advisory
agreement,  the Manager is not liable for any loss  sustained  by reason of good
faith  errors  or  omissions  in  connection  with  any  matters  to  which  the
agreement(s)  relate.  The  agreements  permit the Manager to act as  investment
advisor for any other person,  firm or corporation.  Pursuant to each agreement,
the Manager is permitted to use the name  "Oppenheimer" in connection with other
investment  companies  for which it may act as  investment  advisor  or  general
distributor.  If the Manager  shall no longer act as  investment  advisor to the
Funds,  the  Manager  may  withdraw  the  right  of the  Funds  to use the  name
"Oppenheimer" as part of their names.

      The Manager is  controlled by  Oppenheimer  Acquisition  Corp.,  a holding
company  owned  in part by  senior  management  of the  Manager  and  ultimately
controlled  by  Massachusetts  Mutual  Life  Insurance  Company,  a mutual  life
insurance company that also advises pension plans and investment companies.  The
Manager  has  been  an  investment  advisor  since  January  1960.  The  Manager
(including  subsidiaries  and an  affiliate)  managed  more than $120 billion in
assets as of March 31, 2000,  including other Oppenheimer funds with more than 5
million shareholder accounts.  The Manager is located at Two World Trade Center,
34th Floor, New York, New York 10048-0203. OppenheimerFunds Services, a division
of the Manager,  acts as transfer and shareholder  servicing agent on an at-cost
basis for both Insured  Municipal  Fund and Municipal  Bond Fund and for certain
other open-end funds managed by the Manager and its affiliates.

      Distribution  -  Pursuant  to  a  General  Distributor's   Agreement,  the
Distributor  acts as principal  underwriter in a continuous  public  offering of
shares of both  Insured  Municipal  Fund and  Municipal  Bond  Fund,  but is not
obligated to sell a specific number of shares. Expenses normally attributable to
sales,  including  advertising and the cost of printing and mailing prospectuses
other  than  those  furnished  to  existing  shareholders,   are  borne  by  the
Distributor,  except for those which  Distributor is paid under each Fund's Rule
12b-1 Distribution and Service Plan described below.

      Both Funds have adopted a Service Plan and  Agreement  under Rule 12b-1 of
the Investment  Company Act for their Class A shares.  Each Plan  reimburses the
Distributor  for a portion of its costs incurred in connection with the personal
service and  maintenance of accounts that hold Class A shares.  Under each plan,
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
currently uses all of those fees to compensate dealers, brokers, banks and other
financial  institutions quarterly for providing personal service and maintenance
of accounts of their customers that hold Class A shares.

      Both Funds have adopted Distribution and Service Plans under Rule 12b-1 of
the 1940 Act for their  Class B and Class C shares.  Each Plan  compensates  the
Distributor  for its  services  and  costs in  distributing  Class B and Class C
shares and servicing accounts. Under each Plan, the Funds pay the Distributor an
asset-based  sales  charge  at an  annual  rate of up to  0.75%  per  year.  The
Distributor  also receives a service fee of 0.25% per year under each plan.  All
fee  amounts  are  computed  on the  average  annual  net  assets  of the  class
determined as of the close of each regular  business day of each Fund. The Class
B asset-based sales charge is retained by the Distributor. After the first year,
the Class C asset-based  sales charge is paid to the broker-dealer as an ongoing
concession for shares that have been outstanding for a year or more.

      Purchases and  Redemptions  - Both Funds are part of the  OppenheimerFunds
complex of funds.  The procedures for  purchases,  exchanges and  redemptions of
shares of the Funds are the same.  Shares of either  Fund may be  exchanged  for
shares of the same class of other Oppenheimer funds offering such shares.

      Both Funds have a maximum  initial sales charge of 4.75% on Class A shares
for  purchases  of less than  $50,000.  The sales charge of 4.75% is reduced for
purchases  of Class A shares of  $50,000  or more.  Investors  who  purchase  $1
million or more of Class A shares pay no  initial  sales  charge but may have to
pay a sales charge of up to 1% if the shares are sold within 12 calendar  months
from the end of the calendar  month during  which they were  purchased.  Class B
shares of the Funds are sold without a front-end sales charge but may be subject
to a contingent deferred sales charge ("CDSC") upon redemption  depending on the
length of time the shares are held. The CDSC begins at 5% for shares sold in the
first year and declines to 1% in the sixth year and is eliminated after that.

      Class A, Class B and Class C shares of Municipal Bond Fund received in the
Reorganization will be issued at net asset value,  without a sales charge and no
CDSC  will be  imposed  on any  Insured  Municipal  Fund  shares  exchanged  for
Municipal Bond Fund shares as a result of the Reorganization.  However, any CDSC
that  applies  to  Insured  Municipal  Fund  shares  will  continue  to apply to
Municipal Bond Fund shares received in the Reorganization. Services available to
shareholders  of both Funds include  purchase and  redemption of shares  through
OppenheimerFunds  AccountLink  and PhoneLink (an  automated  telephone  system),
telephone  redemptions,  and exchanges by telephone to other  Oppenheimer  funds
that offer Class A and Class B shares, and reinvestment  privileges.  Please see
"Shareholder   Services,"   below  and  each  Fund's   Prospectus   for  further
information.

      Shareholder  Services - Both Funds offer the same  initial and  subsequent
minimum investment amounts for the purchase of shares.  These amounts are $1,000
and $25, respectively. Both Funds also offer the following privileges: (i) Right
of  Accumulation,  (ii) Letter of Intent,  (iii)  reinvestment  of dividends and
distributions  at net asset  value,  (iv) net asset value  purchases  by certain
individuals and entities,  (v) Asset Builder (automatic  investment) Plans, (vi)
Automatic  Withdrawal and Exchange Plans for  shareholders who own shares of the
Fund valued at $5,000 or more,  (vii)  AccountLink  and PhoneLink  arrangements,
(viii)  exchanges of shares for shares of the same class of certain  other funds
at net asset value, and (ix) telephone redemption and exchange privileges.

      Shareholders  may purchase  shares through  OppenheimerFunds  AccountLink,
which  links  a  shareholder  account  to an  account  at a  bank  or  financial
institution and enables shareholders to send money electronically  between those
accounts to perform a number of types of account transactions. This includes the
purchase of shares  through  the  automated  telephone  system  (PhoneLink)  and
through the Internet.  Exchanges can also be made by telephone, or automatically
through  PhoneLink  or through  the  OppenheimerFunds  Internet  website.  After
AccountLink privileges have been established with a bank account,  shares may be
purchased by telephone in an amount up to $100,000. Shares of either Fund may be
exchanged for shares of certain  Oppenheimer funds at net asset value per share;
however,  shares of a particular  class may be exchanged  only for shares of the
same  class of other  Oppenheimer  funds.  Shareholders  of the Funds may redeem
their  shares  by  written  request,  by  telephone  request  in an amount up to
$100,000  in any  seven-day  period.  Shareholders  may  arrange  to have  share
redemption  proceeds wired to a  pre-designated  account at a U.S. bank or other
financial  institution that is an ACH member,  through AccountLink.  There is no
dollar limit on Internet or telephone redemption proceeds sent to a bank account
when  AccountLink  has been  established.  Shareholders  may also redeem  shares
automatically by telephone by using PhoneLink or the  OppenheimerFunds  Internet
website. Shareholders of Insured Municipal Fund may also have the Transfer Agent
send redemption proceeds of $2,500 or more by Federal Funds wire to a designated
commercial  bank  which  is  a  member  of  the  Federal  Reserve  wire  system.
Shareholders  of Municipal  Bond Fund do not have this option but can still have
the proceeds sent to their bank account through the ACH system.  Shareholders of
both Funds have up to six months to reinvest  redemption proceeds of their Class
A shares which they  purchase  subject to a sales charge or their Class B shares
on which they paid a contingent  deferred sales charge, in Class A shares of the
Funds or other Oppenheimer  funds without paying a sales charge.  Municipal Bond
Fund may  redeem  accounts  valued at less than $500 if the  account  has fallen
below such stated  amount for reasons other than market value  fluctuations  and
Insured  Municipal  Fund may  redeem  accounts  less  then  $200  under the same
conditions.  Both Funds offer Automatic  Withdrawal and Automatic Exchange Plans
under certain conditions.

      Dividends and Distributions - Both Funds attempt to pay dividends on their
Class A shares at a constant  per share level.  There is no assurance  that they
will be able to do so. The Boards of the Funds may change the targeted  dividend
level at any time,  without  prior  notice to  shareholders.  Additionally,  the
amount of dividends  and the  distributions  paid on Class A, Class B or Class C
shares may vary over time,  depending on market  conditions,  the composition of
the Funds'  portfolios,  and expenses borne by the  particular  class of shares.
Dividends  paid on Class A shares  will  generally  be higher than those paid on
Class B or Class C shares,  which  normally  have higher  expenses than Class A.
There  can  be  no  guarantee  that  either  Fund  will  pay  any  dividends  or
distributions.

      Although neither Fund seeks capital gains, either 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 of each year.
The Funds may make  supplemental  distributions  of dividends  and capital gains
following the end of their fiscal years.

                              VOTING INFORMATION

How many votes are necessary to approve the Reorganization Agreement?

      The  affirmative  vote of the holders of a majority of the total number of
shares of Insured  Municipal Fund  outstanding and entitled to vote is necessary
to  approve  the  Reorganization  Agreement  and the  transactions  contemplated
thereby.  Each shareholder will be entitled to one vote for each full share, and
a fractional  vote for each fractional  share of Insured  Municipal Fund held on
the Record Date. If sufficient votes to approve the proposal are not received by
the  date of the  Meeting,  the  Meeting  may be  adjourned  to  permit  further
solicitation of proxies. The holders of a majority of shares entitled to vote at
the  Meeting and present in person of by proxy  (whether  or not  sufficient  to
constitute a quorum) may adjourn the Meeting to permit further  solicitation  of
proxies.  For  purposes of the  Meeting,  a majority of shares  outstanding  and
entitled  to vote,  present in person or  represented  by proxy,  constitutes  a
quorum.

How do I ensure my vote is accurately recorded?

      You can vote in either of two ways:

o     By mail, with the enclosed proxy card.
o     In person at the Meeting.

A proxy card is, in essence, a ballot. If you simply sign and date the proxy but
give  no  voting  instructions,  your  shares  will be  voted  in  favor  of the
Reorganization Agreement.

Can I revoke my proxy?

      Yes.  You may  revoke  your  proxy at any time  before  it is voted by (i)
writing to the  Secretary  of Insured  Municipal  Fund at 6803 South Tucson Way,
Englewood, Colorado 80112 (if received in time to be acted upon); (ii) attending
the Meeting and voting in person;  or (iii)  signing and returning a later-dated
proxy (if returned and received in time to be voted).

What other matters will be voted upon at the Meeting?

      The Board of Trustees of  Oppenheimer  Municipal Fund on behalf of Insured
Municipal  Fund does not intend to bring any matters  before the  Meeting  other
than those  described in this proxy.  It is not aware of any other matters to be
brought before the Meeting by others.  If any other matters  legally come before
the Meeting,  the proxy ballot confers  discretionary  authority with respect to
such  matters,  and it is the  intention of the persons named to vote proxies to
vote in accordance with their judgment on such matters.

Who is entitled to vote?

      Shareholders of record of Insured  Municipal Fund at the close of business
on August 17, 2000, the record date will be entitled to vote at the Meeting.  On
the  record  date,  there  were  6,997,095.417  outstanding  shares  of  Insured
Municipal Fund, consisting of 5,534,821.676 Class A shares,  1,241,101.092 Class
B shares  and  221,172.649  Class C  shares.  On the  record  date,  there  were
58,786,795.816   outstanding  shares  of  Municipal  Bond  Fund,  consisting  of
51,525,237.876  Class A shares,  5,986,263.240  Class B shares and 1,275,294.700
Class C shares.  Under  relevant  state law and the Trust's  charter  documents,
abstentions  and broker  non-votes  will be included for purposes of determining
whether a quorum is  present  at the  Meeting,  but will be treated as votes not
cast and, therefore, will not be counted for purposes of determining whether the
matters to be voted upon at the Meeting have been approved.  Municipal Bond Fund
shareholders do not vote on the Reorganization.

What other solicitations will be made?

      Insured  Municipal  Fund will  request  broker-dealer  firms,  custodians,
nominees and  fiduciaries to forward proxy material to the beneficial  owners of
the shares of record. Insured Municipal Fund may reimburse  broker-dealer firms,
custodians,  nominees and fiduciaries for their reasonable  expenses incurred in
connection with such proxy  solicitation.  In addition to solicitations by mail,
officers of Insured Municipal Fund or officers and employees of OppenheimerFunds
Services,  without extra pay, may conduct additional solicitations personally or
by  telephone  or  telegraph.   Any  expenses  so  incurred  will  be  borne  by
OppenheimerFunds Services. Proxies may also be solicited by a proxy solicitation
firm hired at Insured Municipal Fund's expense.

      Shares  owned  of  record  by  broker-dealers  for the  benefit  of  their
customers ("street account shares") will be voted by the broker-dealer  based on
instructions received from its customers.  If no instructions are received,  and
the broker-dealer does not have discretionary  power to vote such street account
shares under  applicable stock exchange rules,  the shares  represented  thereby
will be considered to be present at the Meeting for purposes of determining  the
quorum, but will have the same effect as a vote "against" the Proposal.

Are there appraisal rights?

      No. Under the 1940 Act,  shareholders do not have rights of appraisal as a
result of the  Reorganization.  Although  appraisal rights are unavailable,  you
have the right to redeem your shares at net asset value until the closing  date.
After the closing date,  you may redeem your new  Municipal  Bond Fund shares or
exchange  them  into  shares  of  certain  other  funds in the  OppenheimerFunds
complex, subject to the terms of the prospectus of the Fund being acquired.

                               W I T N E S S E T H:

WHEREAS, the parties are each open-end investment companies of the management
type; and

WHEREAS, the parties hereto desire to provide for the reorganization pursuant to
Section 368(a)(1) of the Internal Revenue Code of 1986, as amended (the "Code"),
of Insured  Municipal  Fund through the  acquisition  by Municipal  Bond Fund of
substantially  all of the assets of Insured  Municipal  Fund in exchange for the
voting  shares of  beneficial  interest  of Class A,  Class B and Class C shares
("shares") of Municipal  Bond Fund and the  assumption by Municipal Bond Fund of
certain  liabilities of Insured Municipal Fund, which Class A, Class B and Class
C shares of Municipal Bond Fund are to be distributed by Insured  Municipal Fund
pro rata to its shareholders in complete  liquidation of Insured  Municipal Fund
and complete cancellation of its shares;

NOW,  THEREFORE,  in consideration of the mutual promises herein contained,  the
parties hereto agree as follows:

      1.  The  parties   hereto   hereby  adopt  this   Agreement  and  Plan  of
Reorganization  (the  "Agreement")  pursuant to Section 368(a)(1) of the Code as
follows:  The  reorganization  will be comprised of the acquisition by Municipal
Bond Fund of  substantially  all of the  assets  of  Insured  Municipal  Fund in
exchange for Class A, Class B and Class C shares of Municipal  Bond Fund and the
assumption by Municipal Bond Fund of certain  liabilities  of Insured  Municipal
Fund,  followed by the  distribution of such Class A, Class B and Class C shares
of  Municipal  Bond  Fund  to the  respective  Class  A,  Class  B and  Class  C
shareholders  of Insured  Municipal  Fund in exchange for their Class A, Class B
and Class C shares of Insured  Municipal Fund, all upon and subject to the terms
of the Agreement hereinafter set forth.

      The share  transfer  books of Insured  Municipal  Fund will be permanently
closed at the close of business on the Valuation Date (as  hereinafter  defined)
and only redemption requests received in proper form on or prior to the close of
business on the  Valuation  Date shall be fulfilled by Insured  Municipal  Fund;
redemption  requests received by Insured Municipal Fund after that date shall be
treated as requests for the  redemption of the shares of Municipal  Bond Fund to
be distributed to the shareholder in question as provided in Section 5 hereof.

      2. On the  Closing  Date (as  hereinafter  defined),  all of the assets of
Insured  Municipal  Fund on that  date,  excluding  a cash  reserve  (the  "Cash
Reserve") to be retained by Insured Municipal Fund, sufficient in its discretion
for the payment of the expenses of Insured Municipal Fund's  dissolution and its
liabilities,  but not in excess of the amount  contemplated  by  Section  10.E.,
shall be delivered as provided in Section 8 to Municipal  Bond Fund, in exchange
for and against  delivery  to Insured  Municipal  Fund on the Closing  Date of a
number of Class A, Class B and Class C shares of Municipal Bond Fund,  having an
aggregate net asset value equal to the value of the assets of Insured  Municipal
Fund so transferred and delivered.

      3. The net asset value of Class A, Class B and Class C shares of Municipal
Bond  Fund  and  the  value  of the  assets  of  Insured  Municipal  Fund  to be
transferred  shall in each case be determined as of the close of business of The
New York Stock Exchange on the Valuation  Date. The computation of the net asset
value of the Class A, Class B and Class C shares of Municipal  Bond Fund and the
Class A, Class B and Class C shares of Insured  Municipal  Fund shall be done in
the manner used by Municipal Bond Fund and Insured Municipal Fund, respectively,
in the  computation  of such net  asset  value  per  share as set forth in their
respective  prospectuses.  The  methods  used  by  Municipal  Bond  Fund in such
computation shall be applied to the valuation of the assets of Insured Municipal
Fund to be transferred to Municipal Bond Fund.

      Insured  Municipal  Fund shall declare and pay,  immediately  prior to the
Valuation Date, a dividend or dividends  which,  together with all previous such
dividends,  shall have the effect of  distributing to Insured  Municipal  Fund's
shareholders  all of Insured  Municipal  Fund's  investment  company  income for
taxable years ending on or prior to the Closing Date (computed without regard to
any dividends paid) and all of its net capital gain, if any, realized in taxable
years  ending on or prior to the Closing Date (after  reduction  for any capital
loss carry-forward).

      4.   The   closing   (the   "Closing")   shall  be  at  the   offices   of
OppenheimerFunds,  Inc.  (the  "Agent"),  Two World Trade  Center,  New York, NY
10048,  at 4:00 P.M.  New York time on  ________,  2000 or at such other time or
place as the parties may designate or as provided  below (the  "Closing  Date").
The  business  day  preceding  the  Closing  Date is herein  referred  to as the
"Valuation Date."

      In the event that on the Valuation Date either party has,  pursuant to the
Investment Company Act of 1940, as amended (the "Act"), or any rule,  regulation
or order thereunder, suspended the redemption of its shares or postponed payment
therefore,  the Closing  Date shall be  postponed  until the first  business day
after the date when both parties have ceased such  suspension  or  postponement;
provided,  however,  that if such  suspension  shall continue for a period of 60
days beyond the Valuation  Date,  then the other party to the Agreement shall be
permitted to terminate the Agreement  without liability to either party for such
termination.

      5.  In  conjunction  with  the  Closing,   Insured  Municipal  Fund  shall
distribute on a pro rata basis to the shareholders of Insured  Municipal Fund as
of the Valuation Date Class A, Class B and Class C shares of Municipal Bond Fund
received  by Insured  Municipal  Fund on the Closing  Date in  exchange  for the
assets of Insured  Municipal Fund in complete  liquidation of Insured  Municipal
Fund; for the purpose of the distribution by Insured  Municipal Fund of Class A,
Class B and Class C shares of Municipal  Bond Fund to Insured  Municipal  Fund's
shareholders, Municipal Bond Fund will promptly cause its transfer agent to: (a)
credit an appropriate number of Class A, Class B and Class C shares of Municipal
Bond Fund on the books of Municipal Bond Fund to each Class A, Class B and Class
C  shareholder  of  Insured  Municipal  Fund  in  accordance  with a  list  (the
"Shareholder List") of Insured Municipal Fund shareholders received from Insured
Municipal  Fund; and (b) confirm an  appropriate  number of Class A, Class B and
Class C shares  of  Municipal  Bond  Fund to each  Class A,  Class B and Class C
shareholder  of  Insured  Municipal  Fund;  certificates  for  Class A shares of
Municipal Bond Fund will be issued upon written request of a former  shareholder
of Insured  Municipal  Fund but only for whole shares,  with  fractional  shares
credited to the name of the shareholder on the books of Municipal Bond Fund.

      The Shareholder  List shall  indicate,  as of the close of business on the
Valuation  Date, the name and address of each  shareholder of Insured  Municipal
Fund,  indicating  his or her share  balance.  Insured  Municipal Fund agrees to
supply the  Shareholder  List to Municipal  Bond Fund not later than the Closing
Date.  Shareholders of Insured Municipal Fund holding certificates  representing
their shares shall not be required to surrender their  certificates to anyone in
connection with the reorganization.  After the Closing Date, however, it will be
necessary for such  shareholders  to surrender  their  certificates  in order to
redeem,  transfer  or pledge  the  shares of  Municipal  Bond  Fund  which  they
received.

      6. Within one year after the Closing Date,  Insured  Municipal  Fund shall
(a) either pay or make  provision  for  payment  of all of its  liabilities  and
taxes,  and (b) either (i) transfer any remaining  amount of the Cash Reserve to
Municipal Bond Fund, if such remaining  amount (as reduced by the estimated cost
of distributing it to  shareholders)  is not material (as defined below) or (ii)
distribute such remaining amount to the  shareholders of Insured  Municipal Fund
on the Valuation Date.  Such remaining  amount shall be deemed to be material if
the amount to be distributed,  after deduction of the estimated  expenses of the
distribution,  equals or exceeds  one cent per share of Insured  Municipal  Fund
outstanding on the Valuation Date.

      7. Prior to the  Closing  Date,  there shall be  coordination  between the
parties as to their respective portfolios so that, after the Closing,  Municipal
Bond  Fund  will  be in  compliance  with  all of its  investment  policies  and
restrictions.  At the Closing, Insured Municipal Fund shall deliver to Municipal
Bond  Fund two  copies of a list  setting  forth the  securities  then  owned by
Insured Municipal Fund. Promptly after the Closing, Insured Municipal Fund shall
provide  Municipal Bond Fund a list setting forth the respective  federal income
tax bases thereof.

      8. Portfolio  securities or written evidence  acceptable to Municipal Bond
Fund of record ownership  thereof by The Depository Trust Company or through the
Federal  Reserve Book Entry System or any other  depository  approved by Insured
Municipal  Fund  pursuant  to Rule 17f-4 and Rule  17f-5  under the Act shall be
endorsed and delivered,  or  transferred  by appropriate  transfer or assignment
documents, by Insured Municipal Fund on the Closing Date to Municipal Bond Fund,
or at its direction,  to its custodian bank, in proper form for transfer in such
condition as to constitute  good delivery  thereof in accordance with the custom
of brokers and shall be accompanied by all necessary state transfer  stamps,  if
any. The cash  delivered  shall be in the form of  certified  or bank  cashiers'
checks or by bank wire or intra-bank  transfer payable to the order of Municipal
Bond Fund for the account of Municipal  Bond Fund.  Class A, Class B and Class C
shares of Municipal  Bond Fund  representing  the number of Class A, Class B and
Class C shares of  Municipal  Bond Fund being  delivered  against  the assets of
Insured Municipal Fund,  registered in the name of Insured Municipal Fund, shall
be transferred to Insured  Municipal Fund on the Closing Date. Such shares shall
thereupon be assigned by Insured  Municipal Fund to its shareholders so that the
shares of Municipal Bond Fund may be distributed as provided in Section 5.

      If, at the Closing Date, Insured Municipal Fund is unable to make delivery
under this Section 8 to Municipal  Bond Fund of any of its portfolio  securities
or  cash  for the  reason  that  any of such  securities  purchased  by  Insured
Municipal Fund, or the cash proceeds of a sale of portfolio securities, prior to
the Closing Date have not yet been delivered to it or Insured  Municipal  Fund's
custodian, then the delivery requirements of this Section 8 with respect to said
undelivered  securities or cash will be waived and Insured  Municipal  Fund will
deliver to  Municipal  Bond Fund by or on the Closing  Date with respect to said
undelivered  securities or cash executed copies of an agreement or agreements of
assignment in a form reasonably  satisfactory  to Municipal Bond Fund,  together
with such  other  documents,  including  a due bill or due  bills  and  brokers'
confirmation slips as may reasonably be required by Municipal Bond Fund.

      9.  Municipal  Bond Fund  shall not  assume the  liabilities  (except  for
portfolio  securities  purchased  which  have not  settled  and for  shareholder
redemption  and dividend  checks  outstanding)  of Insured  Municipal  Fund, but
Insured Municipal Fund will, nevertheless, use its best efforts to discharge all
known  liabilities,  so far as may be possible,  prior to the Closing Date.  The
cost of printing and mailing the proxies and proxy  statements  will be borne by
Insured Municipal Fund. Insured Municipal Fund and Municipal Bond Fund will bear
the cost of the tax opinion.  Any  documents  such as existing  prospectuses  or
annual  reports  that are  included in that  mailing  will be a cost of the Fund
issuing the document.  Any other  out-of-pocket  expenses of Municipal Bond Fund
and Insured Municipal Fund associated with this reorganization, including legal,
accounting and transfer agent expenses,  will be borne by Insured Municipal Fund
and Municipal Bond Fund, respectively, in the amounts so incurred by each.

ABOUT THE FUND

The Fund's Investment Objective and Strategies
WHAT IS THE  FUND'S  INVESTMENT  OBJECTIVE?  The  Fund  seeks as high a level of
current  interest  income exempt from federal  income taxes as is available from
investing in municipal securities, while attempting to preserve capital.

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

    The Fund  does not limit  its  investments  to  securities  of a  particular
maturity  range,  but  currently  focuses  on  longer-term   securities.   These
investments are more fully explained in "About the Fund's Investments," below.

HOW DO THE PORTFOLIO MANAGER DECIDE WHAT SECURITIES TO BUY OR SELL? In selecting
securities  for the Fund, the portfolio  manager looks  nationwide for municipal
securities using a variety of factors which may change over time and may vary in
particular cases. The portfolio manager currently looks for:
  o Securities that provide high current income, o A wide range of securities to
  diversify the portfolio, o Securities having favorable credit characteristics,
  and o Special situations that provide opportunities for value.

WHO IS THE FUND DESIGNED FOR? The Fund is designed for individual  investors who
are seeking  income  exempt from federal  income  taxes.  The Fund does not seek
capital gains or growth. Because it invests in tax-exempt  securities,  the Fund
is not  appropriate  for  retirement  plan accounts or for investors who want to
pursue capital growth. The Fund is not a complete investment program.

Main Risks of Investing in the Fund
All investments have risks to some degree. The Fund's investments are subject to
changes in their value from a number of factors,  described below. There is also
the  risk  that  poor  security  selection  by the  Fund's  investment  Manager,
OppenheimerFunds, Inc., will cause the Fund to underperform other funds having a
similar  objective.  There  is no  assurance  that  the Fund  will  achieve  its
objective.

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

CREDIT RISK. Municipal securities are debt securities that are subject to credit
risk. Credit risk is the risk that the issuer of a municipal  security might not
make interest and principal  payments on the security as they become due. If the
issuer fails to pay  interest,  the Fund's  income might be reduced,  and if the
issuer fails to repay  principal,  the value of that  security and of the Fund's
shares may be reduced.  Because the Fund can invest as much as 25% of its assets
in municipal securities below investment grade to seek higher income, the Fund's
credit  risks are  greater  than those of funds  that buy only  investment-grade
bonds.  A downgrade in an issuer's  credit rating or other adverse news about an
issuer can reduce a security's market value.

INTEREST RATE RISKS.  Municipal  securities are subject to changes in value when
prevailing  interest  rates  change.  When  interest  rates fall,  the values of
already-issuer  municipal  securities  generally rise. When interest rates rise,
the values of already-issued  municipal  securities generally fall and the bonds
may sell at a discount  from their face  amount.  The  magnitude  of these price
changes  is  generally  greater  for  bonds  with  longer  maturities.  The Fund
currently  focuses on longer term  securities to seek higher income.  Therefore,
its share prices may fluctuate more when interest rates change.

HOW RISKY IS THE FUND OVERALL?  The value of the Fund's investments in municipal
securities  will  change  over time due to a number  of  factors.  They  include
changes in general  bond  market  movements,  the change in value of  particular
bonds  because of an event  affecting the issuer,  or changes in interest  rates
that can affect bond prices  overall.  These changes can affect the value of the
Fund's investments and its prices per share. In the  OppenheimerFunds  spectrum,
the Fund is more  conservative  than some types of taxable  bond funds,  such as
high yield bond funds, but has greater risks than money market funds.

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



The Fund's Past Performance

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

                        [see appendix to the prospectus]

For  the  period  from  1/1/99  through  9/30/99,  the  cumulative  return  (not
annualized) for Class A shares was -2.52%. Sales charges are not included in the
calculations  of return in this bar chart,  and if those charges were  included,
the returns would be less than those shown.  During the 10-year  period shown in
the bar chart,  the highest return (not  annualized) for a calendar  quarter was
8.58% (1Q'95) and the lowest return (not  annualized) for a calendar quarter was
-6.51% (1Q'94).

The Fund's average annual total returns include the applicable sales charge: for
Class A, the current  maximum  initial  sales charge of 4.75%;  for Class B, the
applicable contingent deferred sales charges of 5% (1-year), 2% (5-years) and 1%
(life of class);  for Class C, the 1% contingent  deferred  sales charge for the
1-year period. The returns measure the performance of a hypothetical account and
assume that all dividends and capital gains  distributions  have been reinvested
in additional  shares. The Fund's performance is compared to the Lehman Brothers
Municipal Bond Index,  an unmanaged  index of a broad range of investment  grade
municipal bonds. The index  performance does not consider the effects of capital
gains or  transaction  costs,  and the  Fund's  investments  may  vary  from the
securities in the index.


Fees and Expenses of the Fund

The Fund pays a variety of  expenses  directly  for  management  of its  assets,
administration,  distribution of its shares and other  services.  Those expenses
are  subtracted  from the Fund's assets to calculate the Fund's net asset values
per  share.   All   shareholders   therefore  pay  those  expenses   indirectly.
Shareholders  pay other  expenses  directly,  such as sales  charges and account
transaction  charges.  The following tables are meant to help you understand the
fees  and  expenses  you may pay if you buy and hold  shares  of the  Fund.  The
numbers below are based on the Fund's expenses during the fiscal year ended July
31, 1999.

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

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

If shares are redeemed:      1 year    3 years   5 years  10 years1
--------------------------------------------------------------------
--------------------------------------------------------------------
Class A Shares                $560      $739         $      $1497
                                                934
--------------------------------------------------------------------
--------------------------------------------------------------------
Class B Shares                $668      $820      $1097     $1555
--------------------------------------------------------------------
--------------------------------------------------------------------
Class C Shares                $268      $520         $      $1955
                                                897

If shares are not redeemed:  1 year    3 years   5 years  10 years1
--------------------------------------------------------------------
--------------------------------------------------------------------
Class A Shares                $560      $739      $934      $1497
--------------------------------------------------------------------
--------------------------------------------------------------------
Class B Shares                $168      $520      $897      $1555
--------------------------------------------------------------------
--------------------------------------------------------------------
Class C Shares                $168      $520      $897      $1955

In the first example,  expenses include the initial sales charge for Class A and
the applicable  Class B or Class C contingent  deferred  sales  charges.  In the
second example,  the Class A expenses include the sales charge,  but Class B and
Class C expenses do not include  contingent  deferred sales charges.  1. Class B
expense  for years 7 through  10 are based on Class A  expenses,  since  Class B
shares automatically convert to Class A after 6 years.


About the Fund's Investments
THE FUND'S PRINCIPAL INVESTMENT POLICIES. The allocation of the Fund's portfolio
among  different  types of  investments  will  vary  over  time  based  upon the
Manager's  evaluation  of  economic  and  market  trends.  Under  normal  market
conditions,  the  Fund  attempts  to  invest  100% of its  assets  in  municipal
securities. As a fundamental policy, the Fund invests at least 80% of its assets
in municipal securities.  The Statement of Additional  Information contains more
detailed information about the Fund's investment policies and risks.

    The Manager tries to reduce risks by carefully researching securities before
they are purchased.  The Fund attempts to reduce its exposure to market risks by
diversifying  its investments,  that is, by not holding a substantial  amount of
securities  of any one issuer and by not investing too great a percentage of the
Fund's assets in any one issuer.

    However,  changes in the overall  market prices of municipal  securities and
the income they pay can occur at any time. The yield and share price of the Fund
will change daily based on changes in interest rates and market conditions,  and
in response to other economic events.

MUNICIPAL  SECURITIES.  The Fund  buys  municipal  bonds and  notes,  tax-exempt
commercial paper,  certificates of participation in municipal leases,  and other
debt  obligations.  These debt obligations are issued by state  governments,  as
well as their political  subdivisions (such as cities, towns and counties),  and
their agencies and authorities.  The Fund can also buy securities  issued by the
District of Columbia,  any  commonwealths,  territories  or  possessions  of the
United States, or their respective  agencies,  instrumentalities or authorities,
if the interest paid on the security is not subject to federal individual income
tax (in the  opinion of bond  counsel to the issuer at the time the  security is
issued).

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

    The Fund  can buy  municipal  securities  that  are  "general  obligations,"
secured by the  issuer's  pledge of its full faith,  credit and taxing power for
the  payment  of  principal  and  interest.  The  Fund  can  also  buy  "revenue
obligations,"  payable only from the revenues derived from a particular facility
or class of facilities,  or a specific excise tax or other revenue source.  Some
of these revenue  obligations are private  activity bonds that pay interest that
may be a tax preference for investors subject to alternative minimum tax.

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

    The  Manager  may  rely to some  extent  on  credit  ratings  by  nationally
    recognized  rating  agencies in  evaluating  the credit  risk of  securities
    selected  for the Fund's  portfolio.  It may also use its own  research  and
    analysis.  Many factors affect an issuer's  ability to make timely payments,
    and the credit risks of a particular security may change over time.
Special Credit Risks of Lower-Grade Securities. Lower-grade municipal securities
    may be subject to greater market  fluctuations  and greater risks of loss of
    income and principal than higher-rated municipal securities. Securities that
    are (or that have fallen) below  investment grade entail a greater risk that
    the issuers may not meet their debt obligations.
Municipal  Lease  Obligations.  Municipal  leases  are used by state  and  local
    government  authorities  to  obtain  funds to  acquire  land,  equipment  or
    facilities.  The Fund can  invest  in  certificates  of  participation  that
    represent a  proportionate  interest in payments made under  municipal lease
    obligations.  If the  government  stops  making  payments or  transfers  its
    payment  obligations to a private entity, the obligation could lose value or
    become taxable.

CAN THE FUND'S  INVESTMENT  OBJECTIVE AND POLICIES  CHANGE?  The Fund's Board of
Trustee  can  change  non-fundamental  policies  without  shareholder  approval,
although significant changes will be described in amendments to this Prospectus.
Fundamental policies cannot be changed without the approval of a majority of the
Fund's  outstanding  voting  shares.  The  Fund's  investment   objective  is  a
fundamental  policy. An investment policy or technique is not fundamental unless
this Prospectus or the Statement of Additional Information says that it is.

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

Floating Rate/Variable Rate Obligations. Some municipal securities have variable
    or floating interest rates. Variable rates are adjustable at stated periodic
    intervals.   Floating  rates  are  automatically  adjusted  according  to  a
    specified  market rate for such  investments,  such as the percentage of the
    prime rate of a bank, or the 91-day U.S. Treasury Bill rate.

    Certain  variable  rate bonds known as "inverse  floaters"  pay  interest at
    rates that move in the opposite  direction of yields on short-term  bonds in
    response to market changes. As interest rates rise, inverse floaters produce
    less current  income,  and their market value can become  volatile.  Inverse
    floaters are a type of "derivative  security." Some have a "cap," so that if
    interest rates rise above the "cap," the security pays  additional  interest
    income.  If rates do not rise  above the  "cap,"  the Fund will have paid an
    additional amount for a feature that proves worthless.
Other  Derivatives.  The Fund  can  invest  in  derivative  securities  that pay
    interest  that  depends  on the  change  in  value of an  underlying  asset,
    interest  rate or index.  Options  and  futures  (discussed  below) are also
    examples of  derivatives.  The Fund may use  derivatives  to seek  increased
    returns or to try to hedge  investment  risks.  Examples of external pricing
    mechanisms are interest rate swaps, municipal bond indices or swap indices.
  o There  Are  Special  Risks  in  Using  Derivatives.  If  the  issuer  of the
    derivative  investment  does not pay the amount due, the Fund can lose money
    on its investment.  Also, the underlying security or investment on which the
    derivative is based, and the derivative  itself, may not perform the way the
    Manager  expected it to  perform.  If that  happens,  the Fund will get less
    income than  expected or its share price could  decline.  To try to preserve
    capital,  the  Fund  has  limits  on  the  amount  of  particular  types  of
    derivatives it can hold. For example, the Fund will not invest more than 20%
    of its total assets in inverse floaters.
Putsand Stand-By  Commitments.  The Fund can acquire  "stand-by  commitments" or
    "puts" with respect to municipal  securities.  The Fund obtains the right to
    sell  specified  securities  at  a  set  price  on  demand  to  the  issuing
    broker-dealer or bank. However,  this feature may result in a lower interest
    rate on the security.  The Fund acquires stand-by commitments or puts solely
    to enhance portfolio liquidity.
Illiquid  Securities.  Investments  may be illiquid  because they do not have an
    active trading market,  making it difficult to value them or dispose of them
    promptly at an acceptable  price.  The Fund will not invest more than 15% of
    its net assets in  illiquid  securities.  The Manager  monitors  holdings of
    illiquid  securities  on an ongoing  basis to determine  whether to sell any
    holdings to maintain adequate liquidity. The Fund cannot buy a security that
    has a restriction on its resale.
Hedging. The Fund can buy and sell futures contracts,  put and call options,  or
    enter into  interest  rate swap  agreements.  These are all  referred  to as
    "hedging  instruments."  The  Fund  does  not use  hedging  instruments  for
    speculative  purposes,  and has limits on the use of them. The Fund does not
    use hedging  instruments to a substantial  degree and is not required to use
    them in seeking its goal.  Hedging  involves  risks.  If the Manager  uses a
    hedging   instrument  at  the  wrong  time  or  judges   market   conditions
    incorrectly, the strategy could reduce the Fund's returns.
Temporary  Defensive  Investments.  The Fund can  invest up to 100% of its total
    assets in temporary  defensive  investments during periods of unusual market
    conditions.  Generally  they would be short-term  municipal  securities  but
    could  be  U.S.  government   securities  or  highly-rated   corporate  debt
    securities.  The income from some temporary defensive investments may not be
    tax-exempt,  and therefore when making those  investments the Fund might not
    achieve  its  objective.  The Fund may also hold  cash and cash  equivalents
    pending the investment of proceeds from the sale of Fund shares or portfolio
    securities, or to meet anticipated redemptions of Fund shares.


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

    The Manager has operated as an investment  advisor  since 1960.  The Manager
(including  subsidiaries)  managed  more  than  $110  billion  in  assets  as of
September 30, 1999,  including other Oppenheimer funds, with more than 5 million
shareholder  accounts.  The Manager is located at Two World Trade  Center,  34th
Floor, New York, New York 10048-0203.  Portfolio  Manager.  The Fund's portfolio
manager is Robert E. Patterson, a
    Senior Vice President of the Manager. Mr. Patterson is the person
    principally responsible for the day-to-day management of the Fund's
    portfolio, and has had this responsibility since November 18, 1985. Mr.
    Patterson is a Vice President of the Fund and also an officer and
    portfolio manager of other Oppenheimer funds.
Advisory  Fees.  Under  the  investment  advisory  agreement,  the Fund pays the
    Manager  an  advisory  fee at an annual  rate which  declines  as the Fund's
    assets grow:  0.60% of the first $200 million of average  annual net assets,
    0.55% of the next $100 million, 0.50% of the next $200 million, 0.45% of the
    next $250  million,  0.40% of the next $250  million,  and 0.35% of  average
    annual net assets over $1 billion.  The Fund's  management  fee for its last
    fiscal year ended July 31, 1999,  was 0.52% of average annual net assets for
    each class of shares.


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

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


ABOUT YOUR ACCOUNT

How to Buy Shares
HOW DO YOU BUY SHARES?  You can buy shares several ways, as described below.
The Fund's Distributor, OppenheimerFunds Distributor, Inc., may appoint
servicing agents to accept purchase (and redemption) orders. The Distributor,
in its sole discretion, may reject any purchase order for the Fund's shares.
Buying Shares Through Your Dealer.  You can buy shares through any dealer,
    broker  or  financial  institution  that  has a  sales  agreement  with  the
    Distributor.  Your dealer will place your order with the Distributor on your
    behalf.
Buying Shares Through the Distributor.  Complete an OppenheimerFunds New Account
    Application  and  return  it  with  a  check  payable  to  "OppenheimerFunds
    Distributor,  Inc." Mail it to P.O. Box 5270, Denver, Colorado 80217. If you
    don't list a dealer on the  application,  the  Distributor  will act as your
    agent in buying the shares.  However,  we  recommend  that you discuss  your
    investment  with a financial  advisor  before you make a purchase to be sure
    that the Fund is appropriate for you.
  o Paying by Federal Funds Wire.  Shares purchased  through the Distributor may
    be paid for by Federal Funds wire. The minimum investment is $2,500.  Before
    sending a wire, call the Distributor's  Wire Department at 1.800.525.7048 to
    notify the Distributor of the wire and to receive further instructions.
  o Buying Shares Through OppenheimerFunds  AccountLink.  With AccountLink,  you
    pay for shares by electronic funds transfers from your bank account.  Shares
    are purchased for your account by a transfer of money from your bank account
    through the Automated  Clearing  House (ACH)  system.  You can provide those
    instructions automatically, under an Asset Builder Plan, described below, or
    by telephone instructions using OppenheimerFunds  PhoneLink,  also described
    below. Please refer to "AccountLink," below for more details.
  o Buying Shares  Through Asset Builder Plans.  You may purchase  shares of the
    Fund (and up to four other Oppenheimer funds)  automatically each month from
    your account at a bank or other financial institution under an Asset Builder
    Plan with AccountLink.  Details are in the Asset Builder Application and the
    Statement of Additional Information.
HOW MUCH  MUST  YOU  INVEST?  You can buy Fund  shares  with a  minimum  initial
investment  of $1,000.  You can make  additional  purchases  at any time with as
little as $25. There are reduced minimum  investments  under special  investment
plans.
  o With Asset Builder Plans,  Automatic  Exchange Plans and military  allotment
    plans, you can make initial and subsequent investments for as little as $25.
    You can make  additional  purchases  of at least  $25 by  telephone  through
    AccountLink.
  o The minimum investment  requirement does not apply to reinvesting  dividends
    from the  Fund or other  Oppenheimer  funds (a list of them  appears  in the
    Statement of Additional Information,  or you can ask your dealer or call the
    Transfer Agent),  or reinvesting  distributions  from unit investment trusts
    that have made arrangements with the Distributor.

AT WHAT PRICE ARE SHARES SOLD? Shares are sold at their offering price, which is
the net asset value per share plus any initial  sales charge that  applies.  The
offering price that applies to a purchase order is based on the next calculation
of the net asset value per share that is made after the Distributor receives the
purchase order at its offices in Denver,  Colorado, or after any agent appointed
by the Distributor receives the order and sends it to the Distributor. Net Asset
Value. The Fund calculates the net asset value of each class of
    shares  as of the  close of The New  York  Stock  Exchange,  on each day the
    Exchange is open for trading  (referred to in this  Prospectus as a "regular
    business  day").  The Exchange  normally closes at 4:00 P.M., New York time,
    but  may  close  earlier  on  some  days.  All  references  to  time in this
    Prospectus mean "New York time". The net asset value per share is determined
    by dividing  the value of the Fund's net assets  attributable  to a class by
    the number of shares of that class that are  outstanding.  To determine  net
    asset  value,  the Fund's Board of Trustees has  established  procedures  to
    value the Fund's securities, in general based on market value. The Board has
    adopted special  procedures for valuing illiquid  securities and obligations
    for which market values cannot be readily obtained.
The Offering  Price. To receive the offering price for a particular day, in most
    cases the Distributor or its designated agent must receive your order by the
    time of day The New York Stock  Exchange  closes  that day. If your order is
    received on a day when the  Exchange  is closed or after it has closed,  the
    order will receive the next  offering  price that is  determined  after your
    order is received.
Buying Through a Dealer.  If you buy shares  through a dealer,  your dealer must
    receive the order by the close of The New York Stock  Exchange  and transmit
    it to the Distributor so that it is received before the Distributor's  close
    of business on a regular  business day (normally  5:00 P.M.) to receive that
    day's offering  price.  Otherwise,  the order will receive the next offering
    price that is determined.












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

-------------------------------------------------------------------------------
WHAT  CLASSES OF SHARES DOES THE FUND OFFER?  The Fund  offers  investors  three
different  classes  of  shares.   The  different  classes  of  shares  represent
investments in the same portfolio of securities,  but the classes are subject to
different  expenses and will likely have  different  share prices.  When you buy
shares,  be sure to specify  Class A,  Class B or Class C shares.  If you do not
choose a class, your investment will be made in Class A shares.
-------------------------------------------------------------------------------
Class A Shares.  If you buy Class A shares,  you pay an initial sales charge (on
    investments  up to $1  million).  The amount of that sales  charge will vary
    depending  on the amount you invest.  The sales  charge  rates are listed in
    "How Can You Buy Class A Shares?" below.
-------------------------------------------------------------------------------
Class B Shares. If you buy Class B shares, you pay no sales charge at the
    time of purchase, but you will pay an annual asset-based sales charge. If
    you sell your shares within six years of buying them, you will normally
    pay a contingent deferred sales charge. That sales charge varies
    depending on how long you own your shares,  as described in "How Can You Buy
    Class B Shares?" below.
-------------------------------------------------------------------------------
Class C Shares. If you buy Class C shares, you pay no sales charge at the
    time of purchase, but you will pay an annual asset-based sales charge. If
    you sell your shares within 12 months of buying them, you will normally
    pay a contingent  deferred  sales charge of 1%, as described in "How Can You
    Buy Class C Shares?" below.
-------------------------------------------------------------------------------

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

    The  discussion  below  is  not  intended  to  be  investment  advice  or  a
recommendation,  because each investor's financial considerations are different.
You should  review these factors with your  financial  advisor.  The  discussion
below  assumes  that  you will  purchase  only one  class  of  shares  and not a
combination of shares of different classes.  How Long Do You Expect to Hold Your
Investment? While future financial needs
    cannot be predicted with certainty, knowing how long you expect to hold your
    investment  will assist you in selecting  the  appropriate  class of shares.
    Because of the effect of class-based expenses,  your choice will also depend
    on how much you plan to invest.  For  example,  the  reduced  sales  charges
    available for larger purchases of Class A shares may, over time,  offset the
    effect of paying an initial sales charge on your investment, compared to the
    effect  over time of  higher  class-based  expenses  on shares of Class B or
    Class C .
  o Investing  for the Shorter  Term.  While the Fund is meant to be a long-term
    investment, if you have a relatively short-term investment horizon (that is,
    you plan to hold  your  shares  for not more  than six  years),  you  should
    probably  consider  purchasing Class A or Class C shares rather than Class B
    shares.  That is because of the  effect of the Class B  contingent  deferred
    sales  charge if you redeem  within six years,  as well as the effect of the
    Class B asset-based  sales charge on the investment return for that class in
    the short-term.  Class C shares might be the appropriate  choice (especially
    for  investments of less than  $100,000),  because there is no initial sales
    charge on Class C shares, and the contingent  deferred sales charge does not
    apply to amounts you sell after holding them one year.  However, if you plan
    to invest more than $100,000 for the shorter term,  then as your  investment
    horizon  increases  toward  six  years,  Class  C  shares  might  not  be as
    advantageous as Class A shares. That is because the annual asset-based sales
    charge on Class C shares will have a greater impact on your account over the
    longer term than the reduced  front-end  sales charge  available  for larger
    purchases of Class A shares.

    And for  investors  who  invest $1 million  or more,  in most cases  Class A
    shares will be the most  advantageous  choice, no matter how long you intend
    to hold your shares.  For that reason,  the  Distributor  normally  will not
    accept  purchase  orders of $500,000 or more of Class B shares or $1 million
    or more of Class C shares from a single investor.
  o Investing for the Longer Term.  If you are investing  less than $100,000 for
    the  longer-term,  for  example  for  retirement,  and do not expect to need
    access  to your  money  for  seven  years  or more,  Class B  shares  may be
    appropriate.

    Of  course,  these  examples  are based on  approximations  of the effect of
    current sales charges and expenses  projected  over time,  and do not detail
    all of the considerations in selecting a class of shares. You should analyze
    your  options  carefully  with your  financial  advisor  before  making that
    choice.
Are There  Differences  in Account  Features  That Matter to You?  Some  account
    features (such as  checkwriting)  may not be available to Class B or Class C
    shareholders.  Other features may not be advisable (because of the effect of
    the contingent  deferred sales charge) for Class B or Class C  shareholders.
    Therefore,  you should  carefully review how you plan to use your investment
    account  before  deciding  which class of shares to buy.  Additionally,  the
    dividends payable to Class B and Class C shareholders will be reduced by the
    additional  expenses  borne by those  classes  that are not borne by Class A
    shares,  such as the Class B and Class C asset-based  sales charge described
    below and in the Statement of Additional Information. Share certificates are
    not  available  for Class B and Class C shares,  and if you are  considering
    using  your  shares  as  collateral  for a loan,  that  may be a  factor  to
    consider.  Also,  checkwriting  privileges  are not available for Class B or
    Class C shares.
How Does It Affect Payments to My Broker? A salesperson,  such as a broker,  may
    receive  different  compensation  for  selling  one class of shares than for
    selling  another class. It is important to remember that Class B and Class C
    contingent  deferred  sales charges and  asset-based  sales charges have the
    same purpose as the  front-end  sales charge on sales of Class A shares:  to
    compensate the  Distributor  for commissions and expenses it pays to dealers
    and financial  institutions  for selling  shares.  The  Distributor  may pay
    additional  compensation  from its own  resources to  securities  dealers or
    financial  institutions  based upon the value of shares of the Fund owned by
    the  dealer  or  financial  institution  for  its  own  account  or for  its
    customers.

SPECIAL SALES CHARGE  ARRANGEMENTS  AND WAIVERS.  Appendix C to the Statement of
Additional  Information  details the  conditions for the waiver of sales charges
that apply in certain  cases,  and the special  sales charge rates that apply to
purchases of shares of the Fund by certain groups, or under specified retirement
plan arrangements or in other special types of transactions. To receive a waiver
or special sales charge rate, you must advise the  Distributor  when  purchasing
shares or the Transfer Agent when redeeming  shares that the special  conditions
apply.

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

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

                             Front-End     Front-End
                               Sales         Sales      Commission

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

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

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

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



How   Can You Reduce Sales Charges in Buying Class A Shares? You may be eligible
      to buy Class A shares at  reduced  sales  charge  rates  under the  Fund's
      "Right of  Accumulation"  or a Letter of Intent,  as described in "Reduced
      Sales  Charges" in the  Statement of Additional  Information.  The Class A
      initial  and  contingent  deferred  sales  charges  are not imposed in the
      circumstances  described in "Reduced  Sales  Charges" in the  Statement of
      Additional Information.

HOW CAN YOU BUY CLASS B SHARES?  Class B shares are sold at net asset  value per
share without an initial sales charge.  However,  if Class B shares are redeemed
within 6 years of their  purchase,  a contingent  deferred  sales charge will be
deducted from the  redemption  proceeds.  The Class B contingent  deferred sales
charge is paid to  compensate  the  Distributor  for its  expenses of  providing
distribution-related services to the Fund in connection with the sale of Class B
shares.

    The contingent  deferred sales charge will be based on the lesser of the net
    asset value of the redeemed shares at the time of redemption or the original
    net asset value. The contingent deferred sales charge is not imposed on:
  o the amount of your  account  value  represented  by an increase in net asset
    value over the initial purchase price,
  o shares purchased by the reinvestment of dividends or capital gains
distributions, or
  o shares  redeemed in the special  circumstances  described in the Appendix in
    the Statement of Additional Information.

    To determine  whether the  contingent  deferred  sales  charge  applies to a
    redemption, the Fund redeems shares in the following order:
  1.shares acquired by reinvestment of dividends and capital gains
distributions,
  2.shares  held for over 6 years,  and  3.shares  held the  longest  during the
  6-year period.

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

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

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

HOW CAN YOU BUY CLASS C SHARES?  Class C shares are sold at net asset  value per
share without an initial sales charge.  However,  if Class C shares are redeemed
within 12 months of their purchase,  a contingent  deferred sales charge of 1.0%
will be deducted from the redemption  proceeds.  The Class C contingent deferred
sales charge is paid to compensate the Distributor for its expenses of providing
distribution-related services to the Fund in connection with the sale of Class C
shares.

    The contingent  deferred sales charge will be based on the lesser of the net
    asset value of the redeemed shares at the time of redemption or the original
    net asset value. The contingent deferred sales charge is not imposed on:
  o the amount of your account  value  represented  by the increase in net asset
    value over the initial purchase price,
  o shares purchased by the reinvestment of dividends or capital gains
distributions, or
  o shares  redeemed in the special  circumstances  described in the Appendix to
    the Statement of Additional Information. To determine whether the contingent
    deferred  sales charge  applies to a redemption,  the Fund redeems shares in
    the following order:
  1.shares acquired by reinvestment of dividends and capital gains
    distributions,
  2.shares  held for over 12 months,  and 3.shares  held the longest  during the
  12-month period.

DISTRIBUTION AND SERVICE (12b-1)PLANS.
Service Plan for Class A Shares. The Fund has adopted a Service Plan for Class A
    shares.  It reimburses the  Distributor  for a portion of its costs incurred
    for services provided to accounts that hold Class A shares. Reimbursement is
    made  quarterly  at an annual rate of up to 0.25% of the average  annual net
    assets of Class A shares of the Fund. The Distributor  currently uses all of
    those  fees to  compensate  dealers,  brokers,  banks  and  other  financial
    institutions  quarterly for providing  personal  service and  maintenance of
    accounts of their customers that hold Class A shares.
Distribution  and  Service  Plans for  Class B and Class C Shares.  The Fund has
    adopted  Distribution  and  Service  Plans for Class B and Class C shares to
    compensate the Distributor for its services and costs in distributing  Class
    B and Class C shares and servicing accounts.  Under the plans, the Fund pays
    the  Distributor  an annual  asset-based  sales  charge of 0.75% per year on
    Class B shares  and on Class C  shares.  The  Distributor  also  receives  a
    service fee of 0.25% per year under each plan.

    The  asset-based  sales charge and service fees increase Class B and Class C
    expenses by up to 1.00% of the net assets per year of the respective  class.
    Because these fees are paid out of the Fund's  assets on an on-going  basis,
    over time these fees will increase the cost of your  investment and may cost
    you more than other types of sales charges.


    The  Distributor  uses the service fees to compensate  dealers for providing
    personal  services  for  accounts  that hold Class B or Class C shares.  The
    Distributor  pays the 0.25% service fees to dealers in advance for the first
    year after the shares  were sold by the  dealer.  After the shares have been
    held for a year,  the  Distributor  pays the  service  fees to  dealers on a
    quarterly basis. The Distributor  currently pays a sales commission of 3.75%
    of the purchase price of Class B shares to dealers from its own resources at
    the time of sale. Including the advance of the service fee, the total amount
    paid by the Distributor to the dealer at the time of sales of Class B shares
    is therefore 4.00% of the purchase price. The Distributor  retains the Class
    B asset-based sales charge.

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

information  must be made by  signature-guaranteed  instructions to the Transfer
Agent signed by all shareholders who own the account.

OPPENHEIMERFUNDS  INTERNET WEB SITE. You can obtain  information about the Fund,
as well as your account balance, on the  OppenheimerFunds  Internet web site, at
http://www.oppenheimerfunds.com.   Additionally,   shareholders  listed  in  the
account  registration  (and the dealer of record)  may request  certain  account
transactions  through a special  section of that web site.  To  perform  account
transactions,  you must first obtain a personal  identification  number (PIN) by
calling  the  Transfer  Agent  at  1-800-533-3310.  If you do not  want  to have
Internet  account  transaction  capability  for your  account,  please  call the
Transfer Agent at 1.800.525.7048.

AUTOMATIC  WITHDRAWAL AND EXCHANGE PLANS. The Fund has several plans that enable
you to sell shares  automatically  or exchange them to another  Oppenheimer fund
account on a regular  basis.  Please  call the  Transfer  Agent or  consult  the
Statement of Additional Information for details.

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

How to Sell Shares

You can sell  (redeem)  some or all of your shares on any regular  business day.
Your shares will be sold at the next net asset value calculated after your order
is received in proper form (which means that it must comply with the  procedures
described  below) and is accepted by the Transfer Agent.  The Fund lets you sell
your shares by writing a letter, by using the Fund's  checkwriting  privilege or
by telephone. You can also set up Automatic Withdrawal Plans to redeem shares on
a  regular  basis.  If you have  questions  about any of these  procedures,  and
especially if you are redeeming  shares in a special  situation,  such as due to
the death of the owner, please call the Transfer Agent first, at 1.800.525.7048,
for assistance.

Certain Requests Require a Signature Guarantee. To protect you and the Fund from
    fraud, the following redemption requests must be in writing and must include
    a signature  guarantee  (although  there may be other  situations  that also
    require a signature guarantee):
  o You wish to redeem more than  $100,000 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 being redeemed by someone (such as an Executor) other than the
    owners


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

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

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

HOW DO YOU SELL  SHARES BY  TELEPHONE?  You and your  dealer  representative  of
record may also sell your shares by telephone.  To receive the redemption  price
calculated on a particular  regular  business day, your call must be received by
the Transfer  Agent by the close of The New York Stock  Exchange that day, which
is  normally  4:00 P.M.,  but may be  earlier  on some days.  You may not redeem
shares held under a share certificate by telephone.
  o To redeem shares through a service representative,  call 1.800.852.8457 o To
  redeem shares automatically on PhoneLink, call 1.800.533.3310
    Whichever  method you use,  you may have a check sent to the  address on the
    account  statement,  or, if you have linked  your Fund  account to your bank
    account on AccountLink, you may have the proceeds sent to that bank account.

ARE THERE LIMITS ON AMOUNTS REDEEMED BY TELEPHONE?
Telephone Redemptions Paid by Check. Up to $100,000 may be redeemed by
    telephone  in any 7-day  period.  The check must be payable to all owners of
    record  of the  shares  and  must  be  sent to the  address  on the  account
    statement.  This  service is not  available  within 30 days of changing  the
    address on an account.
Telephone Redemptions Through AccountLink or Wire. There are no dollar limits on
    telephone  redemption  proceeds sent to a bank account  designated  when you
    establish  AccountLink.  Normally the ACH transfer to your bank is initiated
    on the business day after the  redemption.  You do not receive  dividends on
    the  proceeds  of the  shares  you  redeemed  while  they are  waiting to be
    transferred.

    Shareholders  may also have the Transfer Agent send  redemption  proceeds of
    $2,500  or more  by  Federal  Funds  wire to a  designated  commercial  bank
    account. The bank must be a member of the Federal Reserve wire system. There
    is a $10 fee  for  each  Federal  Funds  wire.  To  place a wire  redemption
    request,  call the Transfer Agent at 1.800.852.8457.  The wire will normally
    be  transmitted on the next bank business day after the shares are redeemed.
    There is a  possibility  that the wire may be  delayed  up to seven  days to
    enable  the  Fund to sell  securities  to pay the  redemption  proceeds.  No
    dividends  are  accrued  or paid on the  proceeds  of shares  that have been
    redeemed and are awaiting  transmittal by wire. To establish wire redemption
    privileges  on an account that is already  established,  please  contact the
    Transfer Agent for instructions.

CHECKWRITING.  To write checks against your Fund account, request that privilege
on your account Application,  or contact the Transfer Agent for signature cards.
They must be signed  (with a signature  guarantee)  by all owners of the account
and  returned  to the  Transfer  Agent so that checks can be sent to you to use.
Shareholders  with joint  accounts can elect in writing to have checks paid over
the  signature  of one  owner.  If you  previously  signed a  signature  card to
establish  checkwriting in another  Oppenheimer fund, simply call 1.800.525.7048
to request  checkwriting for an account in this Fund with the same  registration
as the other account.
  o Checks  can be  written to the order of  whomever  you wish,  but may not be
    cashed at the bank.  The checks are  payable  through  the Fund's  custodian
    bank.
  o Checkwriting  privileges are not available for accounts  holding shares that
    are subject to a contingent deferred sales charge.
  o Checks must be written for at least $100.
  o Checks cannot be paid if they are written for more than your account  value.
    Remember:  your shares  fluctuate  in value and you should not write a check
    close to the total account value.
  o You may not write a check that would  require the Fund to redeem shares that
    were  purchased by check or Asset Builder Plan payments  within the prior 10
    days.
  o Don't use your checks if you changed  your Fund  account  number,  until you
    receive new checks.

CAN YOU SELL SHARES THROUGH YOUR DEALER?  The Distributor has made  arrangements
to repurchase Fund shares from dealers and brokers on behalf of their customers.
Brokers or dealers may charge for that  service.  If your shares are held in the
name of your dealer, you must redeem them through your dealer.

How to Exchange Shares

Shares of the Fund may be exchanged for shares of certain  Oppenheimer  funds at
net asset value per share at the time of  exchange,  without  sales  charge.  To
exchange shares, you must meet several conditions:
  o Shares of the fund  selected for exchange must be available for sale in your
    state of residence.
  o The prospectuses of this Fund and the fund whose shares you want to buy must
    offer the exchange privilege.
  o You must hold the  shares you buy when you  establish  your  account  for at
    least 7 days before you can exchange them. After the account is open 7 days,
    you can exchange shares every regular business day.
  o You must meet the minimum  purchase  requirements  for the fund whose shares
    you purchase by exchange.
  o Before exchanging into a fund, you must obtain and read its prospectus.

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

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

HOW DO YOU SUBMIT EXCHANGE REQUESTS?  Exchanges may be requested in writing
or by telephone:
Written Exchange Requests. Submit an OppenheimerFunds Exchange Request form,
    signed by all owners of the account. Send it to the Transfer Agent at the
    address on the Back Cover.
Telephone Exchange  Requests.  Telephone exchange requests may be made either by
    calling a service  representative at  1.800.852.8457,  or by using PhoneLink
    for automated exchanges by calling  1.800.533.3310.  Telephone exchanges may
    be made only between  accounts that are registered with the same name(s) and
    address. Shares held under certificates may not be exchanged by telephone.

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


Shareholder Account Rules and Policies

The Offering  Of  Shares  may be  suspended  during  any  period  in  which  the
    determination  of net asset  value is  suspended,  and the  offering  may be
    suspended  by the Board of Trustees at any time the Board  believes it is in
    the Fund's best interest to do so.
Telephone Transaction Privileges for purchases,  redemptions or exchanges may be
    modified, suspended or terminated by the Fund at any time. If an account has
    more  than  one  owner,  the  Fund and the  Transfer  Agent  may rely on the
    instructions of any one owner.  Telephone  privileges apply to each owner of
    the account and the dealer  representative  of record for the account unless
    the Transfer Agent receives  cancellation  instructions from an owner of the
    account.
The Transfer  Agent Will Record Any  Telephone  Calls to verify data  concerning
    transactions  and has adopted  other  procedures  to confirm that  telephone
    instructions are genuine, by requiring callers to provide tax identification
    numbers and other  account  data or by using PINs,  and by  confirming  such
    transactions in writing.  The Transfer Agent and the Fund will not be liable
    for losses or expenses  arising  out of  telephone  instructions  reasonably
    believed to be genuine.
Redemption Or Transfer  Requests  Will Not Be Honored  Until The Transfer  Agent
    Receives All  Required  Documents  In Proper  Form.  From time to time,  the
    Transfer Agent in its discretion may waive certain of the  requirements  for
    redemptions stated in this Prospectus.
Dealers That Can Perform Account Transactions For Their Clients By Participating
    In  NETWORKING  through the National  Securities  Clearing  Corporation  are
    responsible  for  obtaining  their  clients'  permission  to  perform  those
    transactions,  and are responsible to their clients who are  shareholders of
    the Fund if the dealer performs any transaction erroneously or improperly.
The Redemption  Prices For Shares Will Vary from day to day because the value of
    the securities in the Fund's  portfolio  fluctuates.  The redemption  price,
    which is the net asset value per share,  will normally differ for each class
    of  shares.  The  redemption  value of your  shares may be more or less than
    their original cost.
Payment For Redeemed Shares ordinarily is made in cash. It is forwarded by check
    or  through  AccountLink  or by  Federal  Funds  wire  (as  elected  by  the
    shareholder)  within seven days after the Transfer Agent receives redemption
    instructions in proper form. However, under unusual circumstances determined
    by the  Securities  and  Exchange  Commission,  payment  may be  delayed  or
    suspended.  For accounts registered in the name of a broker-dealer,  payment
    will normally be forwarded within three business days after redemption.
The Transfer  Agent May Delay  Forwarding  A Check or  processing  a payment via
    AccountLink  for  recently  purchased  shares,  but only until the  purchase
    payment has cleared.  That delay may be as much as 10 days from the date the
    shares were  purchased.  That delay may be avoided if you purchase shares by
    Federal Funds wire or certified  check, or arrange with your bank to provide
    telephone  or written  assurance to the  Transfer  Agent that your  purchase
    payment has cleared.
Involuntary Redemptions Of Small Accounts may be made by the Fund if the account
    value has fallen below $500 for reasons  other than the fact that the market
    value of shares has dropped.  In some cases  involuntary  redemptions may be
    made to repay the  Distributor  for losses  from the  cancellation  of share
    purchase orders.
Shares May Be "Redeemed In Kind" under unusual  circumstances (such as a lack of
    liquidity in the Fund's portfolio to meet redemptions).  This means that the
    redemption proceeds will be paid with securities from the Fund's portfolio.
"Backup  Withholding"  of  Federal  income tax may be  applied  against  taxable
    dividends,  distributions and redemption proceeds  (including  exchanges) if
    you fail to furnish  the Fund your  correct,  certified  Social  Security or
    Employer  Identification  Number when you sign your  application,  or if you
    under-report your income to the Internal Revenue Service.
To  Avoid Sending  Duplicate  Copies Of Materials To  Households,  the Fund will
    mail only one copy of each  annual and  semi-annual  report to  shareholders
    having the same last name and address on the Fund's records.  However,  each
    shareholder may call the Transfer Agent at 1.800.525.7048 to ask that copies
    of those materials be sent personally to that shareholder.

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

    The Fund  attempts to pay  dividends on Class A shares at a constant  level.
There is no  assurance  that it will be able to do so. The Board of Trustees may
change  the  targeted  dividend  level at any  time,  without  prior  notice  to
shareholders.  Additionally, the amount of those dividends and the distributions
paid on Class B and C shares may vary over time, depending on market conditions,
the  composition of the Fund's  portfolio,  and expenses borne by the particular
class of  shares.  Dividends  and  distributions  paid on  Class A  shares  will
generally  be higher than for Class B and Class C shares,  which  normally  have
higher  expenses  than Class A. The Fund cannot  guarantee  that it will pay any
dividends or distributions.

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

WHAT ARE YOUR CHOICES  FOR RECEIVING DISTRIBUTIONS?  When you open your
account, specify on your application how you want to receive your dividends
and distributions. You have four options:
Reinvest All Distributions in the Fund. You can elect to reinvest all
    dividends and capital gains distributions in additional shares of the Fund.
Reinvest Dividends or Capital Gains. You can elect to reinvest some
    distributions  (dividends,  short-term  capital  gains or long-term  capital
    gains  distributions)  in the  Fund  while  receiving  the  other  types  of
    distributions  by check or having  them sent to your  bank  account  through
    AccountLink.
Receive All  Distributions  in Cash.  You can  elect to  receive a check for all
    dividends  and capital  gains  distributions  or have them sent to your bank
    through AccountLink.
Reinvest  Your  Distributions  in  Another  OppenheimerFunds  Account.  You  can
    reinvest  all   distributions  in  the  same  class  of  shares  of  another
    Oppenheimer fund account you have established.


TAXES. Dividends paid from net investment income earned by the Fund on municipal
securities  will be excludable from gross income for Federal  individual  income
tax  purposes.  A portion of a dividend  that is derived from  interest  paid on
certain  "private  activity  bonds" may be an item of tax  preference if you are
subject to the  alternative  minimum tax. If the Fund earns  interest on taxable
investments,  any  dividends  derived  from  those  earnings  will be taxable as
ordinary income to shareholders.
    Dividends and capital gains  distributions  may be subject to state or local
taxes.  Long-term  capital  gains are taxable as  long-term  capital  gains when
distributed  to  shareholders.  It does not  matter  how long you have held your
shares.  Dividends  paid from  short-term  capital gains are taxable as ordinary
income.  Whether you reinvest your  distributions  in additional  shares or take
them in cash,  the tax treatment is the same.  Every year the Fund will send you
and the IRS a  statement  showing  the amount of any  taxable  distribution  you
received in the previous year as well as the amount of your  tax-exempt  income.
Remember There May be Taxes on Transactions. Even though the Fund seeks to
    distribute tax-exempt income to shareholders, you may have a capital gain or
    loss when you sell or exchange  your  shares.  A capital gain or loss is the
    difference  between  the  price  you paid for the  shares  and the price you
    received  when you sold them.  Any capital gain is subject to capital  gains
    tax.
Returns of Capital Can Occur. In certain cases,  distributions  made by the Fund
    may be considered a non-taxable  return of capital to shareholders.  If that
    occurs, it will be identified in notices to shareholders.

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

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

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

Additional Information About the Fund's Investment Policies and Risks

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

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

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

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

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

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

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

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

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

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

       |_| Revenue Bonds. The principal security for a revenue bond is generally
the net revenues derived from a particular facility, group of facilities, or, in
some cases,  the  proceeds  of a special  excise tax or other  specific  revenue
source.  Revenue bonds are issued to finance a wide variety of capital projects.
Examples include electric, gas, water and sewer systems; highways,  bridges, and
tunnels; port and airport facilities; colleges and universities; and hospitals.

      Although  the  principal  security  for these types of bonds may vary from
bond to bond,  many  provide  additional  security in the form of a debt service
reserve fund that may be used to make  principal  and  interest  payments on the
issuer's obligations. Housing finance authorities have a wide range of security,
including   partially  or  fully  insured  mortgages,   rent  subsidized  and/or
collateralized  mortgages,  and/or the net revenues from housing or other public
projects.  Some  authorities  provide further  security in the form of a state's
ability (without obligation) to make up deficiencies in the debt service reserve
fund.

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

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

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

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

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

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

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

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

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

      A  "substantial  user"  of  such  facilities  is  defined  generally  as a
"non-exempt  person who  regularly  uses part of a facility"  financed  from the
proceeds  of exempt  facility  bonds.  Generally,  an  individual  will not be a
"related  person" under the Internal  Revenue Code unless such individual or the
individual's   immediate  family  (spouse,   brothers,   sisters  and  immediate
descendants)  own directly or indirectly in the aggregate more than 50% in value
of the equity of a corporation or partnership which is a "substantial user" of a
facility financed from the proceeds of exempt facility bonds.

      |X| Municipal  Notes.  Municipal  securities  having a maturity  (when the
security  is  issued)  of less than one year are  generally  known as  municipal
notes.  Municipal  notes  generally are used to provide for  short-term  working
capital needs.  Some of the types of municipal  notes the Fund can invest in are
described below.

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

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

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

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

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

      |X| Municipal Lease Obligations. The Fund's investments in municipal lease
obligations  may be through  certificates of  participation  that are offered to
investors by public  entities.  Municipal leases may take the form of a lease or
an installment purchase contract issued by a state or local government authority
to obtain funds to acquire a wide variety of equipment and facilities.

      Some municipal lease securities may be deemed to be "illiquid" securities.
Their  purchase  by the Fund would be limited as  described  below in  "Illiquid
Securities."  From  time to time  the Fund may  invest  more  than 5% of its net
assets in municipal  lease  obligations  that the Manager has  determined  to be
liquid under guidelines set by the Board of Trustees.  Those guidelines  require
the Manager to evaluate:
      |_| the frequency of trades and price quotations for such securities;  |_|
      the number of dealers or other  potential  buyers  willing to  purchase or
      sell such securities;  |_| the availability of market-makers;  and |_| the
      nature of the trades for such securities.

      Municipal  leases  have  special  risk   considerations.   Although  lease
obligations do not constitute general  obligations of the municipality for which
the  municipality's  taxing power is pledged,  a lease  obligation is ordinarily
backed by the  municipality's  covenant to budget for,  appropriate and make the
payments due under the lease  obligation.  However,  certain  lease  obligations
contain  "non-appropriation"  clauses which provide that the municipality has no
obligation to make lease or installment purchase payments in future years unless
money is appropriated  for that purpose on a yearly basis.  While the obligation
might be secured by the lease, it might be difficult to dispose of that property
in case of a default.

      Projects  financed with  certificates of  participation  generally are not
subject to state constitutional debt limitations or other statutory requirements
that may apply to other municipal  securities.  Payments by the public entity on
the obligation  underlying the certificates  are derived from available  revenue
sources.  That  revenue  might be  diverted  to the  funding of other  municipal
service  projects.  Payments of interest  and/or  principal  with respect to the
certificates  are not  guaranteed and do not constitute an obligation of a state
or any of its political subdivisions.

      In addition to the risk of "non-appropriation," municipal lease securities
do not have as highly liquid a market as conventional municipal bonds. Municipal
leases,  like  other  municipal  debt  obligations,  are  subject to the risk of
non-payment of interest or repayment of principal by the issuer.  The ability of
issuers of  municipal  leases to make timely  lease  payments  may be  adversely
affected in general economic downturns and as relative governmental cost burdens
are reallocated among federal,  state and local governmental units. A default in
payment of income would  result in a reduction  of income to the Fund.  It could
also result in a reduction in the value of the municipal lease and that, as well
as a default in  repayment of  principal,  could result in a decrease in the net
asset value of the Fund. While the Fund holds such securities,  the Manager will
also evaluate the  likelihood of a continuing  market for these  securities  and
their credit quality.


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

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

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

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

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

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

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

      Insurance coverage can be in one of three methods:
|_|   a mutual fund "Portfolio  Insurance Policy" issued by Financial  Guaranty
        Insurance Company,
|_|   a "Secondary Market Insurance Policy," or
|_|     a "New Issue Insurance Policy" obtained by the issuer or the underwriter
        of the security at the time of its original issuance.

      If a municipal security is already covered by a New Issue Insurance Policy
or Secondary Market Insurance Policy,  then that security  typically will not be
additionally  insured  under a Portfolio  Insurance  Policy  issued by Financial
Guaranty  Insurance  Company.  New Issue Insurance  Policies or Secondary Market
Insurance  Policies may be issued by Financial  Guaranty Insurance Company or by
other insurers.

      The insurance  policies  discussed above insure the scheduled  payments of
all principal and interest on the covered municipal securities as those payments
fall due. The  insurance  does not  guarantee  the market value of the municipal
securities  or the value of the shares of the Fund.  Except as described  below,
insurance of municipal  securities  the Fund buys has no effect on the net asset
value or redemption price of the shares of the Fund.

      The  insurance  of  principal  refers  to the  face  or par  value  of the
security,  and is not  affected  by the price paid  therefor  by the Fund or the
market  value of the  security.  Payment of a claim  under an  insurance  policy
depends on the  claims-paying  ability of the  insurer  and by the Fund makes no
representations that any insurer will be able to meet its commitments.

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

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

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

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

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

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

      When  purchasing  a Secondary  Market  Insurance  Policy,  the Fund pays a
single  pre-determined  premium.  The Fund  thereby  obtains  insurance  against
non-payment  of scheduled  principal and interest for the remaining  term of the
security,  regardless  of whether  the Fund owns the  security.  That  insurance
coverage  will be  non-cancellable  and  will  continue  in force so long as the
insured security is outstanding.  Acquiring that type of policy enables the Fund
to sell  the  municipal  security  to a third  party as an  "AAA"-rated  insured
security at a market price higher than what otherwise might be obtainable if the
security were sold without the insurance coverage. That rating is not automatic,
however,  and must  specifically  be  requested  from  Standard  & Poor's  for a
security.  This type of policy likely would be purchased if, the Manager, thinks
that the market  value or net proceeds of a sale of the insured  security  would
exceed the current value of the security  (without  insurance)  plus the cost of
the policy.  Any difference  between a security's market value as an "AAA"-rated
security and its market value  without  that rating,  including  the cost of the
insurance  single  premium,  would  inure  to the  Fund in  determining  its net
realized capital gain or loss the sale of the security.

      The Fund can purchase  insurance under a Secondary Market Insurance Policy
in lieu of a Portfolio Insurance Policy at any time, regardless of the effect on
the market value of the underlying  municipal security,  if the Manager believes
such insurance  would best serve the Fund's  interests in meeting its objectives
and policies.  The Fund can purchase a Secondary  Market  Insurance  Policy on a
security that is currently in default as to payments by the issuer to enable the
Fund to sell the  security on an insured  basis rather than be obligated to hold
the  defaulted  security  in its  portfolio  in  order  to  continue  in force a
Portfolio Insurance Policy on that security.

       |_| Financial  Guaranty  Insurance  Company.  The information below about
Financial Guaranty Insurance Company is derived from publicly-available  sources
believed reliable by the Manager.  Financial Guaranty Insurance Company is a New
York stock insurance company, with principal offices at 115 Broadway,  New York,
New York, 10006. Financial Guaranty Insurance Company, domiciled in the State of
New York, commenced its business of providing insurance and financial guaranties
for a variety of investment  instruments in January,  1984.  Financial  Guaranty
Insurance  Company is a  subsidiary  of FGIC  Corporation,  a  Delaware  holding
company.  FGIC  Corporation  is a  wholly-owned  subsidiary of General  Electric
Capital  Corporation.  Neither FGIC  Corporation  nor General  Electric  Capital
Corporation  are obligated to pay the debts of or the claims  against  Financial
Guaranty Insurance Company.

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

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

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

      The agent  will  disburse  to the Fund the face  amount of  principal  and
interest  which is then due for payment but is unpaid by reason of nonpayment by
the issuer. However it will do so only upon receipt by the agent of (i) evidence
of the Fund's  right to receive  payment of the  principal  or interest  due for
payment and (ii) evidence,  including any appropriate instruments of assignment,
that all of the rights to payment of the  principal  or interest due for payment
thereupon  shall vest in  Financial  Guaranty  Insurance  Company.  The proceeds
attributable to interest  payments will be tax-exempt.  Upon such payment by the
agent,  Financial  Guaranty Insurance Company will be fully subrogated to all of
the Fund's rights under the defaulted  obligation,  which  includes the right of
Financial  Guaranty  Insurance  Company to obtain payment from the issuer to the
extent of amounts paid by Financial Guaranty Insurance Company to the Fund.

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

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

      The  interest  rate on a floating  rate  demand  note is based on a stated
prevailing  market rate,  such as a bank's prime rate, the 91-day U.S.  Treasury
Bill rate, or some other standard,  and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is also based
on a stated  prevailing  market rate but is adjusted  automatically at specified
intervals of not less than one year. Generally, the changes in the interest rate
on such  securities  reduce the  fluctuation in their market value.  As interest
rates  decrease  or  increase,   the  potential  for  capital   appreciation  or
depreciation is less than that for fixed-rate  obligations of the same maturity.
The Manager may determine that an unrated  floating rate or variable rate demand
obligation  meets the Fund's  quality  standards  by reason of being backed by a
letter  of credit  or  guarantee  issued  by a bank  that  meets  those  quality
standards.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

      In a  repurchase  transaction,  the Fund  acquires  a security  from,  and
simultaneously  resells it to an approved  vendor for delivery on an agreed upon
future  date.  The resale  price  exceeds the  purchase  price by an amount that
reflects an agreed-upon  interest rate effective for the period during which the
repurchase  agreement is in effect.  Approved  vendors  include U.S.  commercial
banks,  U.S.  branches  of  foreign  banks  or  broker-dealers  that  have  been
designated  a primary  dealer in  government  securities,  which meet the credit
requirements set by the Manager from time to time.

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

      Repurchase  agreements,  considered  "loans" under the Investment  Company
Act,  are  collateralized  by the  underlying  security.  The Fund's  repurchase
agreements  require  that at all times  while  the  repurchase  agreement  is in
effect,  the  collateral's  value must equal or exceed the  repurchase  price to
fully  collateralize the repayment  obligation.  However, if the vendor fails to
pay the resale price on the delivery date, the Fund may incur costs in disposing
of the collateral and may experience losses if there is any delay in its ability
to do so. The Manager will monitor the vendor's creditworthiness to confirm that
the vendor is financially sound and will  continuously  monitor the collateral's
value.

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

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

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

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

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

      When it lends securities, the Fund receives amounts equal to the dividends
or  interest  on the  loaned  securities.  It also  receives  one or more of (a)
negotiated  loan fees, (b) interest on securities  used as  collateral,  and (c)
interest on  short-term  debt  securities  purchased  with the loan  collateral.
Either  type of  interest  may be  shared  with the  borrower.  The Fund may pay
reasonable  finder's,  administrative  or other  fees in  connection  with these
loans.  The terms of the  Fund's  loans  must meet  applicable  tests  under the
Internal Revenue Code and must permit the Fund to reacquire loaned securities on
five days' notice or in time to vote on any important matter.

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

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

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

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

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

      A "municipal bond index" assigns relative values to the municipal bonds in
the index, and is used as the basis for trading long-term municipal bond futures
contracts.  Municipal  bond index  futures are similar to interest  rate futures
except that  settlement is made only in cash. The obligation  under the contract
may also be satisfied by entering into an offsetting  contract.  The  strategies
which the Fund  employs in using  municipal  bond index  futures  are similar to
those with regard to interest rate futures.

      No money is paid by or received  by the Fund on the  purchase or sale of a
futures  contract.  Upon entering into a futures  transaction,  the Fund will be
required  to  deposit  an  initial  margin  payment  in cash or U.S.  Government
securities with the futures commission merchant (the "futures broker").  Initial
margin  payments  will be  deposited  with the  Fund's  custodian  in an account
registered in the futures  broker's name.  However,  the futures broker can gain
access to that account only under certain specified conditions. As the future is
marked to market  (that is, its value on the Fund's books is changed) to reflect
changes  in its market  value,  subsequent  margin  payments,  called  variation
margin, will be paid to or by the futures broker daily.

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

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

      Duration is a volatility  measure  that refers to the expected  percentage
change  in the  value of a debt  security  resulting  from a change  in  general
interest  rates  (measured  by each 1%  change  in the  rates  on U.S.  Treasury
securities).  For example, if a bond has an effective duration of three years, a
1%  increase in general  interest  rates would be expected to cause the value of
the bond to fall about 3%.  There are risks  that this type of futures  strategy
will  not  be  successful.  U.S.  Treasury  bonds  might  perform  better  on  a
duration-adjusted basis than municipal bonds, and the assumptions about duration
that were used might be incorrect (for example,  the duration of municipal bonds
relative to U.S. Treasury Bonds might turn out to be greater than anticipated).

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

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

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

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

      The Fund's custodian, or a securities depository acting for the custodian,
will act as the Fund's  escrow  agent  through  the  facilities  of the  Options
Clearing  Corporation  ("OCC"),  as to the  investments  on  which  the Fund has
written calls traded on exchanges,  or as to other acceptable escrow securities.
In that way, no margin will be required for such transactions.  OCC will release
the securities on the expiration of the calls or upon the Fund's entering into a
closing purchase transaction.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

      The Fund's option activities could affect its portfolio  turnover rate and
brokerage  commissions.  The exercise of calls written by the Fund may cause the
Fund to sell related  portfolio  securities,  thus increasing its turnover rate.
The exercise by the Fund of puts on securities will cause the sale of underlying
investments,  increasing  portfolio  turnover.  Although the decision whether to
exercise a put it holds is within the Fund's control,  holding a put might cause
the Fund to sell the related investments for reasons that would not exist in the
absence of the put.

      The Fund could pay a brokerage commission each time it buys a call or put,
sells a call, or buys or sells an underlying  investment in connection  with the
exercise of a call or put. Such commissions  might be higher on a relative basis
than  the  commissions   for  direct   purchases  or  sales  of  the  underlying
investments. Premiums paid for options are small in relation to the market value
of the underlying  investments.  Consequently,  put and call options offer large
amounts of leverage.  The leverage offered by trading in options could result in
the Fund's net asset value being more  sensitive  to changes in the value of the
underlying investment.

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

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

      The risk of  imperfect  correlation  increases as the  composition  of the
Fund's portfolio diverges from the securities  included in the applicable index.
To compensate  for the imperfect  correlation  of movements in the price of debt
securities  being hedged and movements in the price of the hedging  instruments,
the Fund might use  hedging  instruments  in a greater  dollar  amount  than the
dollar amount of debt securities being hedged.  It might do so if the historical
volatility of the prices of the debt securities being hedged is greater than the
historical volatility of the applicable index.

      The ordinary  spreads  between prices in the cash and futures  markets are
subject to distortions  due to differences in the natures of those markets.  All
participants   in  the  futures  markets  are  subject  to  margin  deposit  and
maintenance   requirements.   Rather  than  meeting  additional  margin  deposit
requirements,  investors  may close out  futures  contracts  through  offsetting
transactions  which could distort the normal  relationship  between the cash and
futures markets. From the point of view of speculators, the deposit requirements
in the  futures  markets  are  less  onerous  than  margin  requirements  in the
securities  markets.  Therefore,  increased  participation by speculators in the
futures markets may cause temporary price distortions.

      The Fund can use  hedging  instruments  to  establish  a  position  in the
municipal  securities  markets as a  temporary  substitute  for the  purchase of
individual  securities  (long  hedging).  It is possible  that the market  might
decline.  If the Fund then concludes not to invest in such securities because of
concerns that there might be further market  decline or for other  reasons,  the
Fund will  realize a loss on the  hedging  instruments  that is not  offset by a
reduction in the purchase price of the securities.

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

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

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

      The Fund can enter into swap transactions with appropriate  counterparties
pursuant to master netting agreements.  A master netting agreement provides that
all swaps done between the Fund and that counterparty under the master agreement
shall be regarded as parts of an integral agreement.  If on any date amounts are
payable under one or more swap transactions, the net amount payable on that date
shall be paid. In addition, the master netting agreement may provide that if one
party  defaults  generally or on one swap,  the  counterparty  can terminate the
swaps with that party.  Under master netting  agreements,  if there is a default
resulting  in a loss to one  party,  that  party's  damages  are  calculated  by
reference to the average cost of a  replacement  swap with respect to each swap.
The  gains  and  losses on all  swaps  are then  netted,  and the  result is the
counterparty's gain or loss on termination. The termination of all swaps and the
netting  of  gains  and  losses  on  termination  is  generally  referred  to as
"aggregation."

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

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

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

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

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

Investment Restrictions

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

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

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

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

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

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

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

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

      |_| The Fund cannot borrow money, except from banks for temporary purposes
in amounts not in excess of 5% of the value of the Fund's  assets.  No assets of
the Fund may be pledged, mortgaged or hypothecated except to secure a borrowing,
and in that case no more than 10% of the Fund's  total  assets  may be  pledged,
mortgaged or hypothecated. Borrowings may not be made for leverage, but only for
liquidity  purposes  to satisfy  redemption  requests  when the  liquidation  of
portfolio securities is considered inconvenient or disadvantageous. However, the
Fund can enter into when-issued and  delayed-delivery  transactions as described
in this Statement of Additional Information.

      |_| The Fund  cannot make loans.  However,  the Fund can  purchase or hold
debt obligations,  repurchase agreements and other instruments and securities it
is permitted to own and may lend its portfolio  securities and other investments
it owns.

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

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

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

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

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

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

      Unless the Prospectus or Statement of Additional Information states that a
percentage  restriction applies on an ongoing basis, it applies only at the time
the Fund makes an investment.  In that case the Fund need not sell securities to
meet  the  percentage  limits  if the  value  of  the  investment  increases  in
proportion to the size of the Fund.

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

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

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

How the Fund Is Managed

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

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

      |X|  Classes  of Shares.  The Board of  Trustees  has the  power,  without
shareholder  approval,  to divide  unissued  shares of the Fund into two or more
classes.  The Board has done so,  and the Fund  currently  has three  classes of
shares,  Class A, Class B and Class C. All classes invest in the same investment
portfolio.  Shares  are  freely  transferable.   Each  share  has  one  vote  at
shareholder  meetings,  with fractional shares voting  proportionally on matters
submitted to the vote of shareholders. Each class of shares:
      |_|                       has its own dividends and distributions,
      |_|             pays  certain  expenses  which may be  different  for the
   different classes,
      |_|             may have a different net asset value,
      |_|             may have  separate  voting rights on matters in which the
        interests  of one class are  different  from the  interests  of another
        class, and
      |_|             votes  as a class  on  matters  that  affect  that  class
alone.

      |X|  Meetings of  Shareholders.  As a series of a  Massachusetts  business
trust,  the Fund is not  required  to hold,  and does not plan to hold,  regular
annual meetings of shareholders. The Fund will hold meetings when required to do
so by the  Investment  Company Act or other  applicable  law. It will also do so
when a shareholder  meeting is called by the Trustees or upon proper  request of
the shareholders.

      Shareholders  have the right,  upon the  declaration in writing or vote of
two-thirds of the outstanding shares of Oppenheimer  Municipal Fund, to remove a
Trustee. The Trustees will call a meeting of shareholders to vote on the removal
of a Trustee  upon the  written  request  of the  record  holders  of 10% of the
outstanding  shares of  Oppenheimer  Municipal  Fund. If the Trustees  receive a
request from at least 10 shareholders stating that they wish to communicate with
other  shareholders to request a meeting to remove a Trustee,  the Trustees will
then either make the shareholder lists of a series of Oppenheimer Municipal Fund
available  to  the  applicants  or  mail  their   communication   to  all  other
shareholders at the applicants'  expense.  The  shareholders  making the request
must have been  shareholders  for at least six months and must hold  shares of a
series of Oppenheimer  Municipal Fund valued at $25,000 or more or  constituting
at least 1% of the outstanding shares of Oppenheimer  Municipal Fund,  whichever
is less.  The Trustees may also take other action as permitted by the Investment
Company Act.

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

1.    For the 1999 calendar year.
2. Mr.   Armstrong  and  Mr.  Bowen  were  not  Trustees  or  Directors  of  the
   Denver-based Oppenheimer funds during 1998.

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

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

      |X| Major  Shareholders.  As of December  28,  1999,  the only persons who
owned of record or who were known by the Fund to own  beneficially 5% or more of
the Fund's outstanding shares were:

      Merrill  Lynch  Pierce  Fenner & Smith,  Inc.,  4800 Deer Lake Drive East,
      Floor 3, Jacksonville,  Florida,  32246-6484,  which owned 680.935 Class B
      shares, representing 6.99% of the Class B shares then outstanding.

      Merrill  Lynch  Pierce  Fenner & Smith,  Inc.,  4800 Deer Lake Drive East,
      Floor 3, Jacksonville, Florida, 32246-6484, which owned 63,879.633 Class C
      shares, representing 21.68% of the Class C shares then outstanding.

      Margie  H.  Madak  Trust,  8619 W.  Sunnyside  Avenue,  Chicago,  Illinois
      60656-4149,  which owned  29,762.828  of the Class C shares,  representing
      10.10% of the Class C shares then outstanding.

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

      |X| Code of Ethics.  The Fund, the Manager and the Distributor 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.  Covered persons include
 persons with knowledge of the investments and investment intentions of the Fund
 and  other  funds  advised  by the  Manager.  The Code of  Ethics  does  permit
 personnel  subject to the Code to invest in  securities,  including  securities
 that may be purchased or held by the Fund,  subject to a number of restrictions
 and  controls.  Compliance  with the Code of Ethics is carefully  monitored and
 enforced by the Manager.

       The Code of Ethics is an  exhibit to the  Fund's  registration  statement
 filed with the  Securities  and  Exchange  Commission  and can be reviewed  and
 copied at the SEC's Public  Reference Room in  Washington,  D.C. You can obtain
 information  about the  hours of  operation  of the  Public  Reference  Room by
 calling  the SEC at  1-202-942-8090.  The Code of Ethics  can also be viewed as
 part of the Fund's  registration  statement on the SEC's EDGAR  database at the
 SEC's Internet web site at  http://www.sec.gov.  Copies may be obtained,  after
 paying a  duplicating  fee,  by  electronic  request  at the  following  E-mail
 address:  [email protected].,  or by  writing  to the SEC's  Public  Reference
 Section, Washington, D.C. 20549-0102.


      |X| The Investment  Advisory  Agreement.  The Manager provides  investment
advisory  and  management  services  to the Fund  under an  investment  advisory
agreement  between the Manager and the Fund. The Manager selects  securities for
the Fund's portfolio and handles its day-to day business.  The portfolio manager
of the Fund is  employed  by the  Manager  and is the person who is  principally
responsible for the day-to-day  management of the Fund's  investment  portfolio.
Other members of the Manager's Fixed-Income Portfolio Team provide the portfolio
manager  with  research  and counsel in  managing  the Fund's  investments.  The
agreement  requires  the  Manager,  at its  expense,  to  provide  the Fund with
adequate office space, facilities and equipment. It also requires the Manager to
provide  and  supervise  the  activities  of  all  administrative  and  clerical
personnel required to provide effective  corporate  administration for the Fund.
Those  responsibilities  include the compilation and maintenance of records with
respect to the  Fund's  operations,  the  preparation  and  filing of  specified
reports, and the composition of proxy materials and registration  statements for
continuous public sale of shares of the Fund.

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

              1998                           $545,563

              1999                           $601,513

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

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

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

Brokerage Policies of the Fund

Brokerage Provisions of the Investment Advisory Agreement.  One of the duties of
the Manager under the investment advisory agreement is to buy and sell portfolio
securities for the Fund. The investment advisory agreement allows the Manager to
use  broker-dealers  to effect  the  Fund's  portfolio  transactions.  Under the
agreement,  the Manager may employ those broker-dealers  (including "affiliated"
brokers,  as that term is defined in the  Investment  Company Act) that,  in the
Manager's best judgment based on all relevant factors, will implement the Fund's
policy to obtain,  at  reasonable  expense,  the "best  execution"  of portfolio
transactions.  "Best execution"  refers to prompt and reliable  execution at the
most  favorable  price  obtainable.   The  Manager  need  not  seek  competitive
commission bidding. However, the Manager is expected to minimize the commissions
paid to the extent  consistent  with the  interest  and  policies of the Fund as
established by its Board of Trustees.

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

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

      Most securities  purchases made by the Fund are in principal  transactions
at net prices.  The Fund usually  deals  directly with the selling or purchasing
principal or market maker without incurring charges for the services of a broker
on its behalf unless the Manager determines that a better price or execution may
be obtained  by using the  services  of a broker.  Therefore,  the Fund does not
incur  substantial   brokerage  costs.   Portfolio   securities  purchased  from
underwriters  include  a  commission  or  concession  paid by the  issuer to the
underwriter in the price of the security.  Portfolio  securities  purchased from
dealers include a spread between the bid and asked price.

      The Fund seeks to obtain prompt  execution of orders at the most favorable
net prices. In an option  transaction,  the Fund ordinarily uses the same broker
for the purchase or sale of the option and any  transaction in the investment to
which the option  relates.  Other funds  advised by the Manager have  investment
objectives  and  policies  similar to those of the Fund.  Those  other funds may
purchase or sell the same  securities  as the Fund at the same time as the Fund,
which could affect the supply and price of the  securities.  When possible,  the
Manager tries to combine concurrent orders to purchase or sell the same security
by more than one of the accounts  managed by the Manager or its affiliates.  The
transactions  under those combined orders are averaged as to price and allocated
in accordance with the purchase or sale orders actually placed for each account.

      The  investment   advisory  agreement  permits  the  Manager  to  allocate
brokerage for research services.  The research services provided by a particular
broker may be useful only to one or more of the advisory accounts of the Manager
and  its  affiliates.  Investment  research  received  by the  Manager  for  the
commissions  paid by those other accounts may be useful both to the Fund and one
or more of the Manager's other  accounts.  Investment  research  services may be
supplied  to the Manager by a third  party at the  instance of a broker  through
which trades are placed.  Investment  research services include  information and
analyses on particular  companies  and  industries as well as market or economic
trends and portfolio  strategy,  market  quotations  for portfolio  evaluations,
information systems,  computer hardware and similar products and services.  If a
research  service also assists the Manager in a  non-research  capacity (such as
bookkeeping  or other  administrative  functions),  then only the  percentage or
component   that  provides   assistance   to  the  Manager  in  the   investment
decision-making process may be paid in commission dollars.

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

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

Distribution and Service Plans

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

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

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

      Each  plan has been  approved  by a vote of the Board of  Trustees  of the
Fund,  including a majority of the Independent  Trustees,  6 cast in person at a
meeting called for the purpose of voting on that plan.

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

      Unless a plan is  terminated  as described  below,  the plan  continues in
effect  from year to year,  but only if the  Fund's  Board of  Trustees  and its
Independent  Trustees  specifically  vote  annually to approve its  continuance.
Approval must be by a vote cast in person at a meeting called for the purpose of
voting on continuing  the plan. A plan may be terminated at any time by the vote
of a majority  of the  Independent  Trustees  or by the vote of the holders of a
"majority" (as defined in the Investment  Company Act) of the outstanding shares
of that class.

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

      While the plans are in effect,  the  Treasurer  of the Fund shall  provide
separate  written  reports on the plans to the Fund's Board of Trustees at least
quarterly  for its review.  The reports  shall detail the amount of all payments
made  under a plan and the  purpose  for which the  payments  were  made.  Those
reports are subject to the review and  approval of the  Independent  Trustees in
the exercise of their fiduciary duty.

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

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

      |X| Class A Service Plan.  Under the Class A service plan, the Distributor
currently  uses the fees it receives  from the Fund to pay brokers,  dealers and
other financial institutions (they are referred to as "recipients") for personal
services and account  maintenance  services they provide for their customers who
hold Class A shares.  The services  include,  among others,  answering  customer
inquiries about the Fund,  assisting in establishing and maintaining accounts in
the Fund,  making the Fund's  investment  plans  available and  providing  other
services at the request of the Fund or the  Distributor.  The Distributor  makes
payments to plan  recipients  quarterly at an annual rate not to exceed 0.25% of
the average  annual net assets of Class A shares held in accounts of the service
provider or their customers.

      For the fiscal year ended September 30, 1999,  payments under the Plan for
Class A shares  totaled  $245,096,  all of which was paid by the  Distributor to
recipients.  That included $12,398 paid to an affiliate of the Distributor.  Any
unreimbursed  expenses the Distributor incurs with respect to Class A shares for
any fiscal year may not be recovered in subsequent  years.  The  Distributor may
not use  payments  received  under the  Class A plan to pay any of its  interest
expenses, carrying charges, other financial costs, or allocation of overhead.

      |X| Class B and Class C Service and Distribution  Plans.  Under each plan,
service fees and distribution  fees are computed on the average of the net asset
value of  shares in the  respective  class,  determined  as of the close of each
regular  business day during the period.  The Class B and Class C plans  provide
for the Distributor to be compensated at a flat rate,  whether the Distributor's
distribution  expenses  are more or less than the amounts paid by the Fund under
the  plans  during  that  period.  The  Class B and  Class C  plans  permit  the
Distributor to retain both the asset-based  sales charges and the service fee on
shares or to pay  recipients  the  service  fee on a  quarterly  basis,  without
payment in  advance.  The types of  services  that  recipients  provide  for the
service  fee are  similar  to the  services  provided  under  the  Class A plan,
described above.

      The  Distributor  presently  intends to pay  recipients the service fee on
Class B and  Class C  shares  in  advance  for the  first  year the  shares  are
outstanding.  After the first year shares are outstanding, the Distributor makes
payments  quarterly  on those  shares.  The advance  payment is based on the net
asset value of shares sold.  Shares  purchased by exchange do not qualify for an
advance  service fee payment.  If Class B or Class C shares are redeemed  during
the first year after their purchase,  the recipient of the service fees on those
shares will be  obligated  to repay the  Distributor  a pro rata  portion of the
advance payment made on those shares.

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

      The  asset-based  sales  charge  on  Class  B and  Class C  shares  allows
investors to buy shares  without a front-end  sales  charge  while  allowing the
Distributor  to  compensate  dealers that sell those shares.  The  Distributor's
actual  expenses  in  selling  Class B and  Class C shares  may be more than the
payments it  receives  from  contingent  deferred  sales  charges  collected  on
redeemed shares and from the Fund under the plans. The Fund pays the asset-based
sales charge to the Distributor for its services rendered in distributing  Class
B and Class C shares.  The payments are made to the  Distributor  in recognition
that the Distributor:
      |_| pays sales  commissions to authorized  brokers and dealers at the time
        of sale and pays service fees as described in the Prospectus,
      |_| may  finance  payment of sales  commissions  and/or the advance of the
        service fee payment to recipients  under the plans,  or may provide such
        financing from its own resources or from the resources of an affiliate,
      |_| employs personnel to support distribution of shares, and |_| bears the
costs of sales literature, advertising and prospectuses (other
        than those  furnished  to  current  shareholders)  and state  "blue sky"
        registration fees and certain other distribution expenses.

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

Performance of the Fund

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

      The Fund's  illustrations of its performance data in  advertisements  must
comply  with  rules of the  Securities  and  Exchange  Commission.  Those  rules
describe  the  types of  performance  data  that may be used and how it is to be
calculated.  In general,  any  advertisement by the Fund of its performance data
must include the average annual total returns for the advertised class of shares
of the Fund.  Those  returns must be shown for the 1, 5 and 10-year  periods (or
the life of the class,  if less) ending as of the most recently  ended  calendar
quarter prior to the  publication  of the  advertisement  (or its submission for
publication).  Certain types of yields may also be shown, provided that they are
accompanied by standardized average annual total returns.

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

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

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

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


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

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

      The symbols above represent the following factors:

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

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

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

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

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

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

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

      The tax-equivalent  yield may be used to compare the tax effects of income
derived  from the Fund with income  from  taxable  investments  at the tax rates
stated.  Your tax bracket is determined by your federal  taxable income (the net
amount  subject to federal  income tax after  deductions  and  exemptions).  The
tax-equivalent  yield table  assumes  that the  investor is taxed at the highest
bracket, regardless of whether a switch to non-taxable investments would cause a
lower bracket to apply.

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

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

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

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

       |_| Cumulative Total Return.  The "cumulative  total return"  calculation
measures  the change in value of a  hypothetical  investment  of $1,000  over an
entire period of years. Its calculation uses some of the same factors as average
annual  total  return,  but it does not  average the rate of return on an annual
basis.  Cumulative  total return is determined as follows:  |_| Total Returns at
Net Asset Value.  From time to time the Fund may also quote a  cumulative  or an
average  annual  total  return "at net asset  value"  (without  deducting  sales
charges) for Class A, Class B or Class C shares. Each is based on the difference
in net asset  value per share at the  beginning  and the end of the period for a
hypothetical  investment in that class of shares (without considering  front-end
or  contingent   deferred  sales  charges)  and  takes  into  consideration  the
reinvestment of dividends and capital gains distributions.

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

      |X| Lipper Rankings. From time to time the Fund may publish the ranking of
the  performance of its Class A, Class B or Class C shares by Lipper  Analytical
Services, Inc. ("Lipper"). Lipper is a widely-recognized independent mutual fund
monitoring  service.  Lipper  monitors the  performance of regulated  investment
companies,  including the Fund, and ranks their  performance for various periods
based on categories  relating to investment  objectives.  The performance of the
Fund is ranked by Lipper  against all other insured  municipal  debt funds.  The
Lipper  performance  rankings  are  based  on total  returns  that  include  the
reinvestment of capital gain  distributions and income dividends but do not take
sales charges or taxes into  consideration.  Lipper also publishes  "peer-group"
indices of the  performance  of all mutual funds in a category  that it monitors
and averages of the performance of the funds in particular categories.

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

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

      The Fund may also compare its total return  ranking to that of other funds
in its  Morningstar  category,  in  addition to its star  rankings.  Those total
return rankings are percentages  from one percent to one hundred percent and are
not risk adjusted. For example, if a fund is in the 94th percentile,  that means
that 94% of the funds in the same category performed better than it did.

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

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

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

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

How to Buy Shares

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

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

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

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

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

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

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

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

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

      A Letter  enables  an  investor  to count  the  Class A and Class B shares
purchased  under the Letter to obtain the reduced sales charge rate on purchases
of Class A shares of the Fund (and other  Oppenheimer  funds) that applies under
the Right of Accumulation to current purchases of Class A shares.  Each purchase
of Class A shares under the Letter will be made at the offering price (including
the sales  charge) that applies to a single  lump-sum  purchase of shares in the
amount intended to be purchased under the Letter.

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

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

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

      |X|  Terms of Escrow That Apply to Letters of Intent.

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

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

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

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

      5.The shares  eligible  for  purchase  under the Letter (or the holding of
which may be counted toward completion of a Letter) include:

(a)     Class A shares sold with a front-end  sales charge or subject to a Class
        A contingent deferred sales charge,

(b)     Class  B  shares  of  other  Oppenheimer  funds  acquired  subject  to a
        contingent deferred sales charge, and

(c)     Class A or Class B shares  acquired  by  exchange  of either (1) Class A
        shares of one of the other  Oppenheimer funds that were acquired subject
        to a Class A initial or contingent  deferred sales charge or (2) Class B
        shares of one of the other  Oppenheimer funds that were acquired subject
        to a contingent deferred sales charge.
      6.Shares  held in escrow  hereunder  will  automatically  be exchanged for
shares of another  fund to which an exchange is  requested,  as described in the
section of the Prospectus  entitled "How to Exchange Shares" and the escrow will
be transferred to that other fund.

Asset Builder Plans.  To establish an Asset Builder Plan to buy shares  directly
from a bank  account,  you must  enclose a check  (the  minimum  is $25) for the
initial purchase with your  application.  Shares purchased by Asset Builder Plan
payments  from bank  accounts  are subject to the  redemption  restrictions  for
recent purchases described in the Prospectus.  Asset Builder Plans are available
only if your bank is an ACH member.  Asset  Builder Plans may not be used to buy
shares of OppenheimerFunds  employer-sponsored  qualified  retirement  accounts.
Asset Builder Plans also enable shareholders of Oppenheimer Cash Reserves to use
their fund account to make monthly  automatic  purchases of shares of up to four
other Oppenheimer funds.

      If you make  payments  from your bank  account to  purchase  shares of the
Fund, your bank account will be debited  automatically.  Normally the debit will
be made two  business  days prior to the  investment  dates you selected on your
Application.  Neither the Distributor,  the Transfer Agent nor the Fund shall be
responsible  for any delays in purchasing  shares that result from delays in ACH
transmissions.

      Before  you  establish  Asset  Builder  payments,   you  should  obtain  a
prospectus  of  the  selected  fund(s)  from  your  financial  advisor  (or  the
Distributor)  and request an  application  from the  Distributor.  Complete  the
application  and return  it.  You may  change  the amount of your Asset  Builder
payment or you can terminate these automatic  investments at any time by writing
to  the  Transfer  Agent.  The  Transfer  Agent  requires  a  reasonable  period
(approximately  10 days) after receipt of your  instructions  to implement them.
The Fund reserves the right to amend,  suspend,  or  discontinue  offering Asset
Builder plans at any time without prior notice.

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

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

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

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

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

      |X|  Allocation of Expenses.  The Fund pays expenses  related to its daily
operations,  such as custodian fees, trustees' fees, transfer agency fees, legal
fees and auditing  costs.  Those  expenses are paid out of the Fund's assets and
are not paid directly by  shareholders.  However,  those expenses reduce the net
asset  value of shares,  and  therefore  are  indirectly  borne by  shareholders
through their investment.

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

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

Determination  of Net Asset Values Per Share.  The net asset values per share of
each class of shares of the Fund are  determined  as of the close of business of
The New York Stock Exchange on each day that the Exchange is open. It is done by
dividing  the value of the Fund's net assets  attributable  to that class by the
number of shares of that  class  that are  outstanding.  The  Exchange  normally
closes at 4:00  P.M.,  New York time,  but may close  earlier on some other days
(for example,  in case of weather  emergencies  or on days falling before a U.S.
holiday).  The Exchange's most recent annual  announcement  (which is subject to
change)  states that it will close on New Year's Day,  Martin  Luther King,  Jr.
Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence Day, Labor Day,
Thanksgiving Day and Christmas Day. It may also close on other days.

      Dealers  other than  Exchange  members  may conduct  trading in  municipal
securities on days on which the Exchange is closed (including  weekends and U.S.
holidays)  or after 4:00 P.M. on a regular  business  day.  The Fund's net asset
values will not be  calculated  on those days,  and the values of some of Fund's
portfolio  securities may change  significantly on those days, when shareholders
cannot purchase or redeem shares.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

How to Sell Shares

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

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

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

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

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

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

(4)     specifically  acknowledges  that if they  choose to permit  checks to be
        honored if there is a single  signature  on checks drawn  against  joint
        accounts,  or accounts for corporations,  partnerships,  trusts or other
        entities,  the  signature  of any  one  signatory  on a  check  will  be
        sufficient to authorize  payment of that check and  redemption  from the
        account,  even if that account is  registered  in the names of more than
        one  person  or  more  than  one  authorized  signature  appears  on the
        Checkwriting card or the Application, as applicable;

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

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

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

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

      |_| Class B shares that were  subject to the Class B  contingent  deferred
      sales charge when redeemed.

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

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

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

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

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

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

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

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

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


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

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

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

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

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

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


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

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

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

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

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

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

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

How to Exchange Shares

As stated in the Prospectus,  shares of a particular class of Oppenheimer  funds
having  more than one class of shares  may be  exchanged  only for shares of the
same class of other Oppenheimer  funds.  Shares of Oppenheimer funds that have a
single class  without a class  designation  are deemed "Class A" shares for this
purpose.  You can obtain a current list showing  which funds offer which classes
by calling the Distributor at 1-800-525-7048.

   o  All of the  Oppenheimer  funds  currently  offer  Class  A, B and C shares
      except Oppenheimer Money Market Fund, Inc., Centennial Money Market Trust,
      Centennial Tax Exempt Trust,  Centennial Government Trust,  Centennial New
      York Tax  Exempt  Trust,  Centennial  California  Tax  Exempt  Trust,  and
      Centennial America Fund, L.P., which only offer Class A shares.
   o  Oppenheimer  Main Street  California  Municipal Fund currently offers only
      Class A and Class B shares.
   o  Class B and Class C shares of  Oppenheimer  Cash  Reserves  are  generally
      available  only by  exchange  from  the  same  class  of  shares  of other
      Oppenheimer funds or through OppenheimerFunds-sponsored 401(k) plans.
   o  Only certain  Oppenheimer  funds currently  offer Class Y shares.  Class Y
      shares of  Oppenheimer  Real Asset Fund may not be exchanged for shares of
      any other fund.
   o  Class M shares of Oppenheimer Convertible Securities Fund may be exchanged
      only  for  Class A  shares  of other  Oppenheimer  funds.  They may not be
      acquired by exchange of shares of any class of any other Oppenheimer funds
      except Class A shares of Oppenheimer Money Market Fund or Oppenheimer Cash
      Reserves acquired by exchange of Class M shares.
   o  Class A shares of Senior  Floating Rate Fund are not available by exchange
      of Class A shares  of other  Oppenheimer  funds.  Class A shares of Senior
      Floating Rate Fund that are exchanged for shares of the other  Oppenheimer
      funds may not be exchanged back for Class A shares of Senior Floating Rate
      Fund.
   o  Class X shares of Limited  Term New York  Municipal  Fund can be exchanged
      only for Class B shares of other Oppenheimer funds and no exchanges may be
      made to Class X shares.
   o  Shares of Oppenheimer  Capital  Preservation Fund may not be exchanged for
      shares of Oppenheimer  Money Market Fund, Inc.,  Oppenheimer Cash Reserves
      or Oppenheimer  Limited-Term Government Fund. Only participants in certain
      retirement plans may purchase shares of Oppenheimer  Capital  Preservation
      Fund, and only those participants may exchange shares of other Oppenheimer
      funds for shares of Oppenheimer Capital Preservation Fund.

      Class A shares of  Oppenheimer  funds may be  exchanged at net asset value
for shares of any money  market fund offered by the  Distributor.  Shares of any
money market fund  purchased  without a sales charge may be exchanged for shares
of  Oppenheimer  funds  offered  with a sales  charge upon  payment of the sales
charge. They may also be used to purchase shares of Oppenheimer funds subject to
a contingent deferred sales charge.

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

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

      |X| How Exchanges Affect Contingent  Deferred Sales Charges. No contingent
deferred  sales charge is imposed on exchanges of shares of any class  purchased
subject to a contingent  deferred  sales  charge.  However,  when Class A shares
acquired  by  exchange of Class A shares of other  Oppenheimer  funds  purchased
subject to a Class A contingent  deferred  sales  charge are redeemed  within 18
months of the end of the calendar month of the initial purchase of the exchanged
Class A shares,  the Class A contingent  deferred sales charge is imposed on the
redeemed  shares.  The Class B  contingent  deferred  sales charge is imposed on
Class B shares  acquired by exchange if they are redeemed  within 6 years of the
initial  purchase  of the  exchanged  Class B  shares.  The  Class C  contingent
deferred sales charge is imposed on Class C shares  acquired by exchange if they
are redeemed  within 12 months of the initial  purchase of the exchanged Class C
shares.

      When Class B or Class C shares are  redeemed  to effect an  exchange,  the
priorities described in "How To Buy Shares" in the Prospectus for the imposition
of the Class B or the Class C contingent  deferred sales charge will be followed
in determining  the order in which the shares are exchanged.  Before  exchanging
shares,  shareholders  should take into  account how the exchange may affect any
contingent  deferred  sales  charge  that  might be  imposed  in the  subsequent
redemption  of remaining  shares.  Shareholders  owning  shares of more than one
class must specify which class of shares they wish to exchange.

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

      |X| Telephone  Exchange Requests.  When exchanging shares by telephone,  a
shareholder  must have an existing  account in the fund to which the exchange is
to be made.  Otherwise,  the  investors  must obtain a  Prospectus  of that fund
before the exchange  request may be submitted.  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.  For  full or  partial
exchanges of an account made by telephone,  any special account features such as
Asset Builder Plans and Automatic  Withdrawal  Plans will be switched to the new
account unless the Transfer Agent is instructed otherwise.

      |X| Processing  Exchange Requests.  Shares to be exchanged are redeemed on
the regular  business day the  Transfer  Agent  receives an exchange  request in
proper form (the "Redemption Date"). Normally, shares of the fund to be acquired
are  purchased on the  Redemption  Date,  but such  purchases  may be delayed by
either  fund up to  five  business  days  if it  determines  that  it  would  be
disadvantaged  by an immediate  transfer of the  redemption  proceeds.  The Fund
reserves the right, in its discretion,  to refuse any exchange  request that may
disadvantage it. For example,  if the receipt of multiple exchange requests from
a dealer might require the disposition of portfolio securities at a time or at a
price  that  might be  disadvantageous  to the  Fund,  the Fund may  refuse  the
request. When your exchange some or all of your shares from one fund to another,
any  special  account  feature  such  as an  Asset  Builder  Plan  or  Automatic
Withdrawal  Plan,  will be switched to the new fund account  unless you tell the
Transfer Agent not to do so. However,  special  redemption and exchange features
such as  Automatic  Exchange  Plans and  Automatic  Withdrawal  Plans  cannot be
switched to an account in Oppenheimer Senior Floating Rate Fund.

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

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

Dividends and Taxes

Dividends and Distributions.  Dividends will be payable on shares held of record
at the time of the previous  determination  of net asset value,  or as otherwise
described in "How to Buy Shares."  Daily  dividends will not be declared or paid
on newly purchased  shares until such time as federal Funds (funds credited to a
member  bank's  account at the  federal  Reserve  Bank) are  available  from the
purchase  payment for such  shares.  Normally,  purchase  checks  received  from
investors  are  converted  to federal  Funds on the next  business  day.  Shares
purchased through dealers or brokers normally are paid for by the third business
day following the placement of the purchase order.

      Shares  redeemed  through the regular  redemption  procedure  will be paid
dividends  through  and  including  the day on which the  redemption  request is
received by the  Transfer  Agent in proper form.  Dividends  will be declared on
shares  repurchased  by a dealer or broker for three business days following the
trade  date (that is, up to and  including  the day prior to  settlement  of the
repurchase).  If all shares in an account are redeemed, all dividends accrued on
shares  of the  same  class  in the  account  will be  paid  together  with  the
redemption proceeds.

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

      Dividends, distributions and the proceeds of the redemption of Fund shares
represented  by checks  returned to the Transfer  Agent by the Postal Service as
undeliverable  will be invested in shares of Oppenheimer Money Market Fund, Inc.
Reinvestment  will be made as  promptly  as  possible  after the  return of such
checks  to the  Transfer  Agent,  to  enable  the  investor  to earn a return on
otherwise  idle funds.  Unclaimed  accounts may be subject to state  escheatment
laws, and the Fund and the Transfer Agent will not be liable to  shareholders or
their representatives for compliance with those laws in good faith.

      The amount of a distribution  paid on a class of shares may vary from time
to time depending on market conditions, the composition of the Fund's portfolio,
and expenses  borne by the Fund or borne  separately  by a class.  Dividends are
calculated  in the same manner,  at the same time and on the same day for shares
of each class. However,  dividends on Class B and Class C shares are expected to
be lower  than  dividends  on Class A shares.  That is due to the  effect of the
asset-based  sales charge on Class B and Class C shares.  Those  dividends  will
also  differ in amount as a  consequence  of any  difference  in net asset value
among the different classes of shares.

Tax  Status of the  Fund's  Dividends  and  Distributions.  The Fund  intends to
qualify  under  the  Internal  Revenue  Code  during  each  fiscal  year  to pay
"exempt-interest dividends" to its shareholders.  Exempt-interest dividends that
are  derived  from  net  investment  income  earned  by the  Fund  on  municipal
securities  will be  excludable  from gross income of  shareholders  for federal
income tax purposes.

      Net  investment  income  includes the allocation of amounts of income from
the  municipal  securities  in the Fund's  portfolio  that are free from federal
income  taxes.  This  allocation  will  be  made  by the  use of one  designated
percentage  applied uniformly to all income dividends paid during the Fund's tax
year.  That  designation  will normally be made following the end of each fiscal
year as to income  dividends  paid in the prior year.  The  percentage of income
designated as tax-exempt  may  substantially  differ from the  percentage of the
Fund's income that was tax-exempt for a given period.

      A portion of the exempt-interest dividends paid by the Fund may be an item
of tax preference for shareholders  subject to the alternative  minimum tax. The
amount of any dividends attributable to tax preference items for purposes of the
alternative  minimum tax will be identified  when tax information is distributed
by the Fund.

      A shareholder receiving a dividend from income earned by the Fund from one
or more of the  following  sources  treats the  dividend  as a receipt of either
ordinary  income or long-term  capital gain in the  computation of gross income,
regardless of whether the dividend is reinvested:

(1)     certain taxable temporary  investments (such as certificates of deposit,
        repurchase  agreements,  commercial  paper and  obligations  of the U.S.
        Government, its agencies and instrumentalities);

(2)   income from securities loans; or


(3)     an excess of net short-term capital gain over net long-term capital loss
        from the Fund.

      The  Fund's  dividends  will not be  eligible  for the  dividends-received
deduction for  corporations.  Shareholders  receiving  Social Security  benefits
should be aware  that  exempt-interest  dividends  are a factor  in  determining
whether such  benefits  are subject to federal  income tax.  Losses  realized by
shareholders  on the  redemption  of Fund  shares  within six months of purchase
(which period may be shortened by  regulation)  will be  disallowed  for federal
income tax purposes to the extent of exempt-interest  dividends received on such
shares.

      If the Fund  qualifies  as a  "regulated  investment  company"  under  the
Internal Revenue Code, it will not be liable for federal income taxes on amounts
paid by it as dividends and distributions.  That qualification  enables the Fund
to "pass through" its income and realized capital gains to shareholders  without
having to pay tax on them. The Fund qualified as a regulated  investment company
in its last fiscal year and intends to qualify in future years, but reserves the
right not to qualify.  The Internal  Revenue  Code  contains a number of complex
tests to  determine  whether the Fund  qualifies.  The Fund might not meet those
tests in a particular year. If it does not qualify, the Fund will be treated for
tax purposes as an ordinary  corporation  and will receive no tax  deduction for
payments of dividends and distributions made to shareholders.

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

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

Additional Information About the Fund

The Distributor.  The Fund's shares are sold through dealers,  brokers and other
financial  institutions  that  have  a  sales  agreement  with  OppenheimerFunds
Distributor,  Inc.  a  subsidiary  of  the  Manager  that  acts  as  the  Fund's
Distributor.  The Distributor also distributes  shares of the other  Oppenheimer
funds and is  sub-distributor  for funds managed by a subsidiary of the Manager.
The Transfer Agent.  OppenheimerFunds  Services, the Fund's Transfer Agent, is a
division  of  the  Manager.   It  is  responsible  for  maintaining  the  Fund's
shareholder  registry  and  shareholder   accounting  records,  and  for  paying
dividends  and  distributions  to  shareholders.  It  also  handles  shareholder
servicing and administrative  functions.  It acts on an "at-cost" basis. It also
acts  as  shareholder   servicing  agent  for  the  other   Oppenheimer   funds.
Shareholders  should direct inquiries about their accounts to the Transfer Agent
at the address and toll-free numbers shown on the back cover.

The Custodian.  The Bank of New York is the custodian bank of the Fund's assets.
The custodian's responsibilities include safeguarding and controlling the Fund's
portfolio  securities  and handling the delivery of such  securities to and from
the Fund.  It will be the  practice of the Fund to deal with the  custodian in a
manner uninfluenced by any banking  relationship the custodian may have with the
Manager and its  affiliates.  The Fund's cash  balances  with the  custodian  in
excess of  $100,000  are not  protected  by  federal  Deposit  Insurance.  Those
uninsured balances may at times be substantial.

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

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

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

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

Long-Term Bond Ratings

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Long-Term Credit Ratings

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

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

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

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

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

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

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

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

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

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

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

The  ratings  from AA to CCC may be  modified  by the  addition of a plus (+) or
minus (-) sign to show relative standing within the major rating categories. The
"r" symbol is attached to the ratings of instruments with significant  noncredit
risks.

Short-Term Issue Credit Ratings

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

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

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

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

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

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

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

International Long-Term Credit Ratings

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

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

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

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

Speculative Grade:

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

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

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

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

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








-------------------------------------------------------------------------------
International Short-Term Credit Ratings
-------------------------------------------------------------------------------
F1: Highest credit quality.  Strongest capacity for timely payment.  May have an
added "+" to denote exceptionally strong credit feature.

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

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

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

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

D:     Default. Denotes actual or imminent payment default.

Duff & Phelps Credit Rating Co. Ratings
-------------------------------------------------------------------------------

-------------------------------------------------------------------------------
Long-Term Debt and Preferred Stock
-------------------------------------------------------------------------------

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

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

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

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

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

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

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

DD:  Defaulted  debt  obligations.  Issuer failed to meet  scheduled  principal
and/or interest payments.

DP:  Preferred stock with dividend arrearages.

Short-Term Debt:

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

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

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

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

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

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

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

                                   Appendix C

        OppenheimerFunds Special Sales Charge Arrangements and Waivers

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

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

For the purposes of some of the waivers  described  below and in the  Prospectus
and Statement of Additional Information of the applicable Oppenheimer funds, the
term  "Retirement  Plan"  refers  to the  following  types of  plans:  (1) plans
qualified under Sections 401(a) or 401(k) of the Internal Revenue
        Code,
(2) non-qualified  deferred  compensation plans, (3) employee benefit plans3 (4)
Group  Retirement  Plans4 (5) 403(b)(7)  custodial  plan accounts (6) Individual
Retirement Accounts ("IRAs"), including traditional IRAs,
        Roth IRAs, SEP-IRAs, SARSEPs or SIMPLE plans

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


 I. Applicability of Class A Contingent Deferred Sales Charges in Certain Cases

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

      There is no initial  sales charge on purchases of Class A shares of any of
the Oppenheimer funds in the cases listed below. However, these purchases may be
subject to the Class A contingent  deferred  sales charge if redeemed  within 18
months of the end of the calendar month of their  purchase,  as described in the
Prospectus (unless a waiver described  elsewhere in this Appendix applies to the
redemption).  Additionally,  on shares  purchased  under these  waivers that are
subject to the Class A contingent  deferred sales charge,  the Distributor  will
pay the  applicable  commission  described  in the  Prospectus  under  "Class  A
Contingent  Deferred  Sales  Charge."7  This  waiver  provision  applies to: |_|
Purchases of Class A shares  aggregating  $1 million or more. |_| Purchases by a
Retirement Plan (other than an IRA or 403(b)(7)
        custodial plan) that:
(1)   buys shares costing $500,000 or more, or
(2)        has, at the time of purchase, 100 or more eligible employees or total
           plan assets of $500,000 or more, or
(3)        certifies  to the  Distributor  that it  projects to have annual plan
           purchases of $200,000 or more.
|_|   Purchases by an OppenheimerFunds-sponsored Rollover IRA, if the
        purchases are made:
(1)        through a broker,  dealer, bank or registered investment adviser that
           has  made  special   arrangements  with  the  Distributor  for  those
           purchases, or
(2)        by a direct  rollover of a distribution  from a qualified  Retirement
           Plan if the administrator of that Plan has made special  arrangements
           with the Distributor for those purchases.
|_|     Purchases  of Class A shares by  Retirement  Plans  that have any of the
        following record-keeping arrangements:
(1)   The record keeping is performed by Merrill Lynch Pierce Fenner & Smith,
           Inc. ("Merrill Lynch") on a daily valuation basis for the
           Retirement Plan. On the date the plan sponsor signs the
           record-keeping service agreement with Merrill Lynch, the Plan must
           have $3 million or more of its assets invested in (a) mutual funds,
           other than those advised or managed by Merrill Lynch Asset
           Management, L.P. ("MLAM"), that are made available under a Service
           Agreement between Merrill Lynch and the mutual fund's principal
           underwriter or distributor, and  (b)  funds advised or managed by
           MLAM (the funds described in (a) and (b) are referred to as
           "Applicable Investments").
(2)   The record keeping for the Retirement Plan is performed on a daily
           valuation basis by a record keeper whose services are provided
           under a contract or arrangement between the Retirement Plan and
           Merrill Lynch. On the date the plan sponsor signs the record
           keeping service agreement with Merrill Lynch, the Plan must have $3
           million or more of its assets (excluding assets invested in money
           market funds) invested in Applicable Investments.
(3)        The record  keeping for a Retirement  Plan is handled under a service
           agreement  with Merrill  Lynch and on the date the plan sponsor signs
           that  agreement,  the Plan  has 500 or more  eligible  employees  (as
           determined by the Merrill Lynch plan conversion manager).
|_|     Purchases by a Retirement Plan whose record keeper had a cost-allocation
        agreement with the Transfer Agent on or before May 1, 1999.

      These  arrangements also apply to shareholders of the following funds when
they merged (were  reorganized)  into various  Oppenheimer funds on November 24,
1995:

  Quest for Value  U.S.  Government Quest   for   Value   New   York

      All of the funds  listed  above are  referred  to in this  Appendix as the
"Former Quest for Value Funds." The waivers of initial and  contingent  deferred
sales charges  described in this Appendix apply to shares of an Oppenheimer fund
that are either:  |_|  acquired by such  shareholder  pursuant to an exchange of
shares of an
        Oppenheimer fund that was one of the Former Quest for Value Funds or |_|
purchased by such shareholder by exchange of shares of another
        Oppenheimer fund that were acquired pursuant to the merger of any of the
        Former  Quest  for  Value  Funds  into that  other  Oppenheimer  fund on
        November 24, 1995.

A.  Reductions or Waivers of Class A Sales Charges.

      |X| Reduced Class A Initial Sales Charge Rates for Certain Former Quest
for Value Funds Shareholders.

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.  The rates in the
table apply if that Association  purchased shares of any of the Former Quest for
Value Funds or received a proposal to purchase such shares from OCC Distributors
prior to November 24, 1995.

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

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

      Purchases made under this arrangement  qualify for the lower of either 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 Right of Accumulation  described
in the applicable  fund's  Prospectus  and Statement of Additional  Information.
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
Distributor.
      |X|  Waiver of Class A Sales Charges for Certain Shareholders.  Class A
shares purchased by the following investors are not subject to any Class A
initial or contingent deferred sales charges:
|_|   Shareholders 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.
|_|     Shareholders  who acquired  shares of any Former Quest for Value Fund by
        merger of any of the portfolios of the Unified Funds.

      |X|  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  purchased by the  following  investors  who were
shareholders of any Former Quest for Value Fund:

      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.

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

      |X| Waivers for Redemptions of Shares Purchased Prior to March 6, 1995. In
the following  cases,  the  contingent  deferred sales charge will be waived for
redemptions  of Class A, Class B or Class C shares of an  Oppenheimer  fund. The
shares must have been  acquired  by the merger of a Former  Quest for Value Fund
into the fund or by exchange  from an  Oppenheimer  fund that was a Former Quest
for Value Fund or into  which  such fund  merged.  Those  shares  must have been
purchased prior to March 6, 1995 in connection  with: |_|  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
|_|     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.

      |X| Waivers for Redemptions of Shares  Purchased on or After March 6, 1995
but Prior to November 24, 1995. In the following cases, the contingent  deferred
sales  charge  will be waived  for  redemptions  of Class A,  Class B or Class C
shares of an Oppenheimer  fund. The shares must have been acquired by the merger
of a  Former  Quest  for  Value  Fund  into  the  fund  or by  exchange  from an
Oppenheimer  fund  that was a Former  Quest For Value  Fund or into  which  such
Former Quest for Value Fund merged.  Those shares must have been purchased on or
after March 6, 1995, but prior to November 24, 1995: |_|  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);
|_|     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
|_|     liquidation of a shareholder's  account if the aggregate net asset value
        of shares held in the account is less than the required  minimum account
        value.

      A shareholder's account will be credited with the amount of any contingent
deferred  sales charge paid on the redemption of any Class A, Class B or Class C
shares of the  Oppenheimer  fund  described  in this section if the proceeds are
invested  in the same  Class of shares in that fund or  another  Oppenheimerfund
within 90 days after redemption.

       V. Special Sales Charge Arrangements for Shareholders of Certain
   Oppenheimer Funds Who Were Shareholders of Connecticut Mutual Investment
                                 Accounts, Inc.

The initial and  contingent  deferred  sale charge rates and waivers for Class A

the  following  Oppenheimer  funds  (each is  referred  to as a  "Fund"  in this
section):  o Oppenheimer  U. S.  Government  Trust,  o Oppenheimer  Bond Fund, o

investment adviser to the Former Connecticut Mutual Funds:

A.  Prior Class A CDSC and Class A Sales Charge Waivers.

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

      Those  shareholders  who are  eligible for the prior Class A CDSC are: (1)
persons whose purchases of Class A shares of a Fund and other Former
        Connecticut  Mutual Funds were  $500,000  prior to March 18, 1996,  as a
        result of direct purchases or purchases  pursuant to the Fund's policies
        on Combined  Purchases or Rights of  Accumulation,  who still hold those
        shares in that Fund or other Former Connecticut Mutual Funds, and
(2)     persons whose intended  purchases under a Statement of Intention entered
        into prior to March 18, 1996, with the former general distributor of the
        Former Connecticut Mutual Funds to purchase shares valued at $500,000 or
        more over a 13-month period entitled those persons to purchase shares at
        net asset  value  without  being  subject  to the Class A initial  sales
        charge.

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

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

      any purchaser,  provided the total initial amount  invested in the Fund or
      any one or more of the Former Connecticut Mutual Funds totaled $500,000 or
      more,  including  investments  made  pursuant to the  Combined  Purchases,
      Statement of Intention and Rights of  Accumulation  features  available at
      the time of the initial  purchase and such investment is still held in one
      or more of the Former  Connecticut  Mutual Funds or a Fund into which such
      Fund merged;
(1)     any  participant  in a qualified  plan,  provided that the total initial
        amount invested by the plan in the Fund or any one or more of the Former
        Connecticut Mutual Funds totaled $500,000 or more;
(2)     Directors  of the  Fund or any one or  more  of the  Former  Connecticut
        Mutual Funds and members of their immediate families;
(3)     employee  benefit  plans  sponsored  by  Connecticut   Mutual  Financial
        Services,   L.L.C.   ("CMFS"),  the  prior  distributor  of  the  Former
        Connecticut Mutual Funds, and its affiliated companies;
(4)     one or more  members of a group of at least 1,000  persons  (and persons
        who  are  retirees  from  such  group)  engaged  in a  common  business,
        profession,  civic or  charitable  endeavor or other  activity,  and the
        spouses  and minor  dependent  children of such  persons,  pursuant to a
        marketing program between CMFS and such group; and
(5)     an  institution  acting as a  fiduciary  on behalf of an  individual  or
        individuals,  if  such  institution  was  directly  compensated  by  the
        individual(s) for recommending the purchase of the shares of the Fund or
        any one or more of the Former  Connecticut  Mutual  Funds,  provided the
        institution had an agreement with CMFS.

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

      Additionally,  Class A shares of a Fund may be  purchased  without a sales
charge by any holder of a variable  annuity contract issued in New York State by
Connecticut  Mutual Life Insurance Company through the Panorama Separate Account
which is beyond the  applicable  surrender  charge  period and which was used to
fund a qualified plan, if that holder  exchanges the variable  annuity  contract
proceeds to buy Class A shares of the Fund.

B. Class A and Class B Contingent Deferred Sales Charge Waivers.

In addition to the waivers  set forth in the  Prospectus  and in this  Appendix,
above,  the contingent  deferred sales charge will be waived for  redemptions of

of a Fund into  Class A or Class B shares of a Former  Connecticut  Mutual  Fund
provided  that  the  Class A or Class B shares  of the  Fund to be  redeemed  or
exchanged  were (i)  acquired  prior to March 18, 1996 or (ii) were  acquired by
exchange from an  Oppenheimer  fund that was a Former  Connecticut  Mutual Fund.
Additionally,  the shares of such Former  Connecticut Mutual Fund must have been
purchased prior to March 18, 1996: (1) by the estate of a deceased  shareholder;
(2) upon the disability of a shareholder, as defined in Section 72(m)(7) of
        the Internal Revenue Code;

        paying a sales charge or commission  in connection  with the purchase of
        shares of any registered investment management company;
(6)     in  connection  with  the  redemption  of  shares  of the  Fund due to a
        combination  with  another  investment  company  by  virtue of a merger,

        annually; or
(9)     as  involuntary  redemptions  of shares by  operation  of law,  or under
        procedures  set forth in the Fund's  Articles  of  Incorporation,  or as
        adopted by the Board of Directors of the Fund.

ABOUT THE FUND

Additional Information About the Fund's Investment Policies and Risks

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

The Fund's  Investment  Policies.  The Fund does not make  investments  with the
objective of seeking capital growth,  since that would generally be inconsistent
with its goal of seeking tax-exempt income. However, the value of the securities
held by the Fund may be affected by changes in general  interest rates.  Because
the current value of debt securities varies inversely with changes in prevailing
interest rates, if interest rates increased after a security was purchased, that
security  would normally  decline in value.  Conversely,  should  interest rates
decrease after a security was purchased, normally its value would rise.

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

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

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

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

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

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

           |_| Revenue  Bonds.  The  principal  security  for a revenue  bond is
generally  the  net  revenues  derived  from a  particular  facility,  group  of
facilities,  or, in some cases,  the  proceeds of a special  excise tax or other
specific  revenue source.  Revenue bonds are issued to finance a wide variety of
capital  projects.  Examples  include  electric,  gas,  water and sewer systems;
highways,  bridges,  and  tunnels;  port and airport  facilities;  colleges  and
universities; and hospitals.

           Although  the  principal  security  for these types of bonds may vary
from  bond to  bond,  many  provide  additional  security  in the form of a debt
service reserve fund that may be used to make principal and interest payments on
the  issuer's  obligations.  Housing  finance  authorities  have a wide range of
security, including partially or fully insured mortgages, rent subsidized and/or
collateralized  mortgages,  and/or the net revenues from housing or other public
projects.  Some  authorities  provide further  security in the form of a state's
ability (without obligation) to make up deficiencies in the debt service reserve
fund.

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

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

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

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

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

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

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

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

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

    A  "substantial   user"  of  such  facilities  is  defined  generally  as  a
"non-exempt  person who  regularly  uses part of a facility"  financed  from the
proceeds  of exempt  facility  bonds.  Generally,  an  individual  will not be a
"related  person" under the Internal  Revenue Code unless such individual or the
individual's   immediate  family  (spouse,   brothers,   sisters  and  immediate
descendants)  own directly or indirectly in the aggregate more than 50% in value
of the equity of a corporation or partnership which is a "substantial user" of a
facility financed from the proceeds of exempt facility bonds.

    |X|  Municipal  Notes.  Municipal  securities  having a  maturity  (when the
security  is  issued)  of less than one year are  generally  known as  municipal
notes.  Municipal  notes  generally are used to provide for  short-term  working
capital needs.  Some of the types of municipal  notes the Fund can invest in are
described below.

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

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

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

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

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

    |X| Municipal Lease  Obligations.  The Fund's investments in municipal lease
obligations  may be through  certificates of  participation  that are offered to
investors by public  entities.  Municipal leases may take the form of a lease or
an installment purchase contract issued by a state or local government authority
to obtain funds to acquire a wide variety of equipment and facilities.

    Some municipal lease  securities may be deemed to be "illiquid"  securities.
Their  purchase  by the Fund would be limited as  described  below in  "Illiquid
Securities."  From  time to time  the Fund may  invest  more  than 5% of its net
assets in municipal  lease  obligations  that the Manager has  determined  to be
liquid under guidelines set by the Board of Trustees.  Those guidelines  require
the Manager to evaluate:
    |_| the frequency of trades and price  quotations for such  securities;  |_|
    the number of dealers or other potential buyers willing to purchase or
      sell such securities;  |_| the availability of market-makers;  and |_| the
    nature of the trades for such securities.

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

    Municipal   leases  have  special  risk   considerations.   Although   lease
obligations do not constitute general  obligations of the municipality for which
the  municipality's  taxing power is pledged,  a lease  obligation is ordinarily
backed by the  municipality's  covenant to budget for,  appropriate and make the
payments due under the lease  obligation.  However,  certain  lease  obligations
contain  "non-appropriation"  clauses which provide that the municipality has no
obligation to make lease or installment purchase payments in future years unless
money is appropriated  for that purpose on a yearly basis.  While the obligation
might be secured by the lease, it might be difficult to dispose of that property
in case of a default.

    Projects  financed  with  certificates  of  participation  generally are not
subject to state constitutional debt limitations or other statutory requirements
that may apply to other municipal  securities.  Payments by the public entity on
the obligation  underlying the certificates  are derived from available  revenue
sources.  That  revenue  might be  diverted  to the  funding of other  municipal
service  projects.  Payments of interest  and/or  principal  with respect to the
certificates  are not  guaranteed and do not constitute an obligation of a state
or any of its political subdivisions.

    In addition to the risk of  "non-appropriation,"  municipal lease securities
do not have as highly liquid a market as conventional municipal bonds. Municipal
leases,  like  other  municipal  debt  obligations,  are  subject to the risk of
non-payment of interest or repayment of principal by the issuer.  The ability of
issuers of  municipal  leases to make timely  lease  payments  may be  adversely
affected in general economic downturns and as relative governmental cost burdens
are reallocated among federal,  state and local governmental units. A default in
payment of income would  result in a reduction  of income to the Fund.  It could
also result in a reduction in the value of the municipal lease and that, as well
as a default in  repayment of  principal,  could result in a decrease in the net
asset value of the Fund.

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

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

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

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

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

Other Investment Techniques and Strategies.  In seeking its objective,  the Fund
may from time to time employ the types of investment  strategies and investments
described below.

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

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

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

    The  interest  rate on a  floating  rate  demand  note is  based on a stated
prevailing  market rate,  such as a bank's prime rate, the 91-day U.S.  Treasury
Bill rate, or some other standard,  and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is also based
on a stated  prevailing  market rate but is adjusted  automatically at specified
intervals of not less than one year. Generally, the changes in the interest rate
on such  securities  reduce the  fluctuation in their market value.  As interest
rates  decrease  or  increase,   the  potential  for  capital   appreciation  or
depreciation is less than that for fixed-rate  obligations of the same maturity.
The Manager may determine that an unrated  floating rate or variable rate demand
obligation  meets the Fund's  quality  standards  by reason of being backed by a
letter  of credit  or  guarantee  issued  by a bank  that  meets  those  quality
standards.

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

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

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

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

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

    When  such  transactions  are  negotiated  the  price  (which  is  generally
expressed in yield terms) is fixed at the time the commitment is made.  Delivery
and  payment  for the  securities  take  place  at a later  date.  Normally  the
settlement  date is within six months of the  purchase  of  municipal  bonds and
notes.  However,  the Fund may, from time to time, purchase municipal securities
having a settlement  date more than six months and possibly as long as two years
or more after the trade date. The securities are subject to change in value from
market  fluctuation  during the settlement  period. The value at delivery may be
less than the  purchase  price.  For  example,  changes in  interest  rates in a
direction other than that expected by the Manager before  settlement will affect
the value of such securities and may cause loss to the Fund.

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

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

    At the time the Fund makes a commitment  to purchase or sell a security on a
when-issued or forward commitment basis, it records the transaction on its books
and reflects  the value of the security  purchased.  In a sale  transaction,  it
records the proceeds to be received,  in  determining  its net asset value.  The
Fund will identify to its Custodian  cash, U.S.  Government  securities or other
high grade debt obligations at least equal to the value of purchase  commitments
until the Fund pays for the investment.

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

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

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

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

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

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

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

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

    |X|  Repurchase  Agreements.  The Fund may  acquire  securities  subject  to
repurchase  agreements.  It may do so for liquidity purposes to meet anticipated
redemptions of Fund shares, or pending the investment of the proceeds from sales
of Fund  shares,  or  pending  the  settlement  of  portfolio  securities.  In a
repurchase  transaction,  the Fund acquires a security from, and  simultaneously
resells it to an approved vendor for delivery on an agreed upon future date. The
resale  price  exceeds  the  purchase  price  by  an  amount  that  reflects  an
agreed-upon  interest rate  effective for the period during which the repurchase
agreement is in effect.  Approved vendors include U.S.  commercial  banks,  U.S.
branches of foreign banks or broker-dealers  that have been designated a primary
dealer in government  securities,  which meet the credit requirements set by the
Fund's Board of Trustees from time to time.

    The majority of these transactions run from day to day. Delivery pursuant to
resale typically will occur within one to five days of the purchase.  Repurchase
agreements  having a maturity beyond seven days are subject to the Fund's limits
on holding illiquid  investments.  There is no limit on the amount of the Fund's
assets that may be subject to repurchase agreements of seven days or less.

    Repurchase agreements,  considered "loans" under the Investment Company Act,
are collateralized by the underlying security.  The Fund's repurchase agreements
require  that at all times  while the  repurchase  agreement  is in effect,  the
collateral's   value  must  equal  or  exceed  the  repurchase  price  to  fully
collateralize  the repayment  obligation.  The Manager will monitor the vendor's
creditworthiness  to  confirm  that the  vendor  is  financially  sound and will
continuously monitor the collateral's value. However, if the vendor fails to pay
the resale price on the delivery  date, the Fund may incur costs in disposing of
the collateral and may experience losses if there is any delay in its ability to
do so.

    |X| Illiquid Securities.  The Fund has percentage  limitations that apply to
purchases  of  illiquid  securities,  as stated in the  Prospectus.  The  Fund's
fundamental  policies  prohibit it from purchasing any restricted  security that
would require registration with the Securities and Exchange Commission before it
could be sold publicly.

    |X| Loans of Portfolio Securities.  To attempt to raise income or raise cash
for liquidity purposes,  the Fund may lend its portfolio  securities to brokers,
dealers and other  financial  institutions.  These loans are limited to not more
than 25% of the value of the Fund's total assets.  There are risks in connection
with  securities  lending.  The  Fund  might  experience  a delay  in  receiving
additional  collateral  to secure a loan,  or a delay in  recovery of the loaned
securities.  The Fund presently does not intend to engage in loans of securities
that will exceed 5% of the value of the Fund's  total assets in the coming year.
Income from securities loans does not constitute  exempt-interest income for the
purpose of paying tax-exempt dividends.

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

    When it lends  securities,  the Fund receives amounts equal to the dividends
or  interest  on the  loaned  securities.  It also  receives  one or more of (a)
negotiated  loan fees, (b) interest on securities  used as  collateral,  and (c)
interest on  short-term  debt  securities  purchased  with the loan  collateral.
Either  type of  interest  may be  shared  with the  borrower.  The Fund may pay
reasonable  finder's,  administrative  or other  fees in  connection  with these
loans.  The terms of the  Fund's  loans  must meet  applicable  tests  under the
Internal Revenue Code and must permit the Fund to reacquire loaned securities on
five days' notice or in time to vote on any important matter.

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

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

    The Fund is not  obligated  to use  hedging  instruments,  even though it is
permitted  to use them in the  Manager's  discretion,  as described  below.  The
Fund's  strategy  of  hedging  with  futures  and  options  on  futures  will be
incidental to the Fund's  investment  activities in the underlying  cash market.
The particular  hedging  instruments the Fund can use are described  below.  The
Fund may employ new hedging  instruments and strategies when they are developed,
if those investment methods are consistent with the Fund's investment  objective
and are permissible under applicable regulations governing the Fund.

    |_| Futures.  The Fund may buy and sell futures  contracts  relating to debt
securities (these are called "interest rate futures") and municipal bond indices
(these are referred to as "municipal bond index futures").

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

    A "municipal  bond index" assigns  relative values to the municipal bonds in
the index, and is used as the basis for trading long-term municipal bond futures
contracts.  Municipal  bond index  futures are similar to interest  rate futures
except that  settlement is made only in cash. The obligation  under the contract
may also be satisfied by entering into an offsetting  contract.  The  strategies
which the Fund  employs in using  municipal  bond index  futures  are similar to
those with regard to interest rate futures.

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

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

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

    Duration is a  volatility  measure  that refers to the  expected  percentage
change in the value of a bond resulting from a change in general  interest rates
(measured  by each 1%  change  in the rates on U.S.  Treasury  securities).  For
example,  if a bond has an effective  duration of three years,  a 1% increase in
general  interest  rates  would be  expected  to cause  the value of the bond to
decline about 3%. There are risks that this type of futures strategy will not be
successful.  U.S.  Treasury  bonds might perform  better on a  duration-adjusted
basis than municipal  bonds,  and the assumptions  about duration that were used
might be incorrect (in this case,  the duration of municipal  bonds  relative to
U.S. Treasury Bonds might have been greater than anticipated).

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

    |_| Writing  Covered Call Options.  The Fund may write (that is, sell) call
options. The Fund's call writing is subject to a number of restrictions:
(1) After the Fund writes a call,  not more than 25% of the Fund's total assets
        may be subject to calls.
(2)     Calls  the Fund  sells  must be listed on a  securities  or  commodities
        exchange  or quoted on NASDAQ,  the  automated  quotation  system of The
        Nasdaq Stock Market, Inc. or traded in the over-the-counter market.
(3)     Each call the Fund writes  must be  "covered"  while it is  outstanding.
        That  means  the Fund  must  own the  investment  on which  the call was
        written.
(4)     The Fund may write calls on futures  contracts  that it owns,  but these
        calls must be covered by securities or other liquid assets that the Fund
        owns and segregates to enable it to satisfy its  obligations if the call
        is exercised.

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

    The Fund's Custodian,  or a securities  depository acting for the Custodian,
will act as the Fund's  escrow  agent  through  the  facilities  of the  Options
Clearing  Corporation  ("OCC"),  as to the  investments  on  which  the Fund has
written calls traded on exchanges,  or as to other acceptable escrow securities.
In that way, no margin will be required for such transactions.  OCC will release
the securities on the expiration of the calls or upon the Fund's entering into a
closing purchase transaction.

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

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

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

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

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

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

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

    When the Fund  purchases  a put,  it pays a  premium.  The Fund then has the
right to sell the underlying  investment to a seller of a  corresponding  put on
the same  investment  during the put period at a fixed exercise  price.  Puts on
municipal  bond  indices are settled in cash.  Buying a put on a debt  security,
interest rate future or municipal  bond index future the Fund owns enables it to
protect  itself  during  the put  period  against a decline  in the value of the
underlying  investment  below the  exercise  price.  If the market  price of the
underlying  investment  is equal to or above the exercise  price and as a result
the put is not  exercised  or  resold,  the put  will  become  worthless  at its
expiration  date.  In that case the Fund will lose its  premium  payment and the
right to sell the underlying  investment.  A put may be sold prior to expiration
(whether or not at a profit).

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

    The Fund's  option  activities  may affect its  portfolio  turnover rate and
brokerage  commissions.  The exercise of calls written by the Fund may cause the
Fund to sell related  portfolio  securities,  thus increasing its turnover rate.
The exercise by the Fund of puts on securities will cause the sale of underlying
investments,  increasing  portfolio  turnover.  Although the decision whether to
exercise a put it holds is within the Fund's control,  holding a put might cause
the Fund to sell the related investments for reasons that would not exist in the
absence of the put.

    The Fund may pay a  brokerage  commission  each  time it buys a call or put,
sells a call, or buys or sells an underlying  investment in connection  with the
exercise of a call or put. Such  commissions  may be higher on a relative  basis
than  the  commissions   for  direct   purchases  or  sales  of  the  underlying
investments. Premiums paid for options are small in relation to the market value
of the underlying  investments.  Consequently,  put and call options offer large
amounts of leverage.  The leverage offered by trading in options could result in
the Fund's net asset value being more  sensitive  to changes in the value of the
underlying investment.

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

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

    The risk of imperfect correlation increases as the composition of the Fund's
portfolio  diverges from the  securities  included in the applicable  index.  To
compensate  for the  imperfect  correlation  of  movements  in the price of debt
securities  being hedged and movements in the price of the hedging  instruments,
the Fund may use hedging  instruments in a greater dollar amount than the dollar
amount  of debt  securities  being  hedged.  It  might  do so if the  historical
volatility of the prices of the debt securities being hedged is greater than the
historical volatility of the applicable index.

    The  ordinary  spreads  between  prices in the cash and futures  markets are
subject to distortions  due to differences in the natures of those markets.  All
participants   in  the  futures  markets  are  subject  to  margin  deposit  and
maintenance   requirements.   Rather  than  meeting  additional  margin  deposit
requirements,  investors  may close out  futures  contracts  through  offsetting
transactions  which could distort the normal  relationship  between the cash and
futures markets. From the point of view of speculators, the deposit requirements
in the  futures  markets  are  less  onerous  than  margin  requirements  in the
securities  markets.  Therefore,  increased  participation by speculators in the
futures markets may cause temporary price distortions.

    The  Fund  may use  hedging  instruments  to  establish  a  position  in the
municipal  securities  markets as a  temporary  substitute  for the  purchase of
individual  securities  (long  hedging).  It is  possible  that the  market  may
decline.  If the Fund then concludes not to invest in such securities because of
concerns that there may be further market decline or for other reasons, the Fund
will realize a loss on the hedging instruments that is not offset by a reduction
in the purchase price of the securities.

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

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

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

    The Fund will enter into swap transactions  with appropriate  counterparties
pursuant to master netting agreements.  A master netting agreement provides that
all swaps done between the Fund and that counterparty under the master agreement
shall be regarded as parts of an integral agreement.  If on any date amounts are
payable under one or more swap transactions, the net amount payable on that date
shall be paid. In addition, the master netting agreement may provide that if one
party  defaults  generally or on one swap,  the  counterparty  may terminate the
swaps with that party.  Under master netting  agreements,  if there is a default
resulting  in a loss to one  party,  that  party's  damages  are  calculated  by
reference to the average cost of a  replacement  swap with respect to each swap.
The  gains  and  losses on all  swaps  are then  netted,  and the  result is the
counterparty's gain or loss on termination. The termination of all swaps and the
netting  of  gains  and  losses  on  termination  is  generally  referred  to as
"aggregation."

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

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

    Under the  Investment  Company Act, when the Fund purchases an interest rate
future  or  municipal  bond  index  future,  it must  maintain  cash or  readily
marketable short-term debt instruments in an amount equal to the market value of
the investments underlying the future, less the margin deposit applicable to it.
The account must be a segregated account or accounts held by its custodian bank.

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

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

Investment Restrictions

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

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

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

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

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

    |_| The Fund cannot  borrow money in excess of 10% of the value of its total
assets.  The  Fund  may  borrow  only  from  banks as a  temporary  measure  for
extraordinary or emergency  purposes,  and not for the purpose of leveraging its
investments.  No  assets  of the Fund may be  pledged,  mortgaged  or  otherwise
encumbered, transferred or assigned to secure a debt. However, the use of escrow
or other  collateral  arrangements  in connection  with hedging  instruments  is
permitted.

    |_| The Fund cannot  invest more than 5% of the value of its total assets in
the  securities of any one issuer.  The Fund cannot acquire more than 10% of the
total value of all outstanding securities of any one issuer. In both cases, this
restriction does not apply to securities of the U.S.  Government or its agencies
or instrumentalities.

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

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

    |_| The Fund cannot  purchase  securities on margin.  However,  the Fund may
obtain such  short-term  credits  that may be  necessary  for the  clearance  of
purchases  and  sales of  securities.  Furthermore,  the  Fund  may make  margin
deposits in connection  with the use of hedging  instruments as permitted by any
of its other fundamental policies.

    |_| The Fund cannot sell securities short.

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

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

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

    |_| The Fund cannot issue any bonds, debentures or senior equity securities.

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

    Unless the Prospectus or Statement of Additional  Information  states that a
percentage  restriction applies on an ongoing basis, it applies only at the time
the Fund makes an investment.  In that case the Fund need not sell securities to
meet  the  percentage  limits  if the  value  of  the  investment  increases  in
proportion to the size of the Fund.

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

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

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

    The Manager has no present intention of investing more than 25% of the total
assets of the Fund in  securities  of issuers  located in the same state,  or in
securities  paying interest  derived from revenues of similar types of projects.
Neither of these is a fundamental  policy, and therefore,  either of them may be
changed  without  shareholder  approval.  Should  any  such  change  occur,  the
Prospectus and/or this Statement of Additional  Information will be supplemented
or revised to reflect the change.

How the Fund Is Managed

Organization  and  History.  The  Fund is an  open-end,  diversified  management
investment  company with an unlimited number of authorized  shares of beneficial
interest.  The Fund was  originally  incorporated  in  Maryland  in 1976 but was
reorganized in 1987 as a Massachusetts business trust.

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

    |_|  Classes  of  Shares.  The  Board of  Trustees  has the  power,  without
shareholder  approval,  to divide  unissued  shares of the Fund into two or more
classes.  The Board has done so,  and the Fund  currently  has three  classes of
shares,  Class A, Class B and Class C. All classes invest in the same investment
portfolio.  Shares  are  freely  transferable.   Each  share  has  one  vote  at
shareholder  meetings,  with fractional shares voting  proportionally on matters
submitted to the vote of shareholders. Each class of shares:
    |_|                         has its own dividends and distributions,
    |_|               pays  certain  expenses  which may be  different  for the
   different classes,
    |_|               may have a different net asset value,
    |_|               may have  separate  voting rights on matters in which the
       interests  of one class are  different  from the  interests  of  another
       class, and
    |_| votes as a class on matters that affect that class alone.

    |_| Meetings of Shareholders. As a Massachusetts business trust, the Fund is
not  required to hold,  and does not plan to hold,  regular  annual  meetings of
shareholders.  The  Fund  will  hold  meetings  when  required  to do so by  the
Investment  Company  Act or  other  applicable  law.  It will  also do so when a
shareholder  meeting is called by the  Trustees  or upon  proper  request of the
shareholders.

    Shareholders  have the  right,  upon the  declaration  in writing or vote of
two-thirds  of the  outstanding  shares of the Fund,  to remove a  Trustee.  The
Trustees will call a meeting of shareholders to vote on the removal of a Trustee
upon the written request of the record holders of 10% of its outstanding shares.
If the  Trustees  receive a request from at least 10  shareholders  stating that
they wish to communicate with other  shareholders to request a meeting to remove
a Trustee,  the  Trustees  will then  either  make the Fund's  shareholder  list
available  to  the  applicants  or  mail  their   communication   to  all  other
shareholders at the applicants'  expense.  The  shareholders  making the request
must have been  shareholders for at least six months and must hold shares of the
Fund  valued  at  $25,000  or more or  constituting  at least  1% of the  Fund's
outstanding  shares,  whichever is less. The Trustees may also take other action
as permitted by the Investment Company Act.

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

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

(1) For the 1998 calendar year.
(2) Includes $1,227 deferred under Deferred Compensation Plan described below.

    |X|  Retirement  Plan for Trustees.  The Fund has adopted a retirement  plan
that  provides for payments to retired  Trustees.  Payments are up to 80% of the
average  compensation paid during a Trustee's five years of service in which the
highest  compensation  was received.  A Trustee must serve as trustee for any of
the New  York-based  Oppenheimer  funds for at least 15 years to be eligible for
the maximum  payment.  Each  Trustee's  retirement  benefits  will depend on the
amount of the Trustee's future compensation and length of service.

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

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

    |X| Major Shareholders. As of November 3 1999, the only persons who owned of
record or were known by the Fund to own  beneficially 5% or more of any class of
the Fund's outstanding shares were the following:

      Merrill Lynch Pierce  Fenner & Smith,  Inc. 4800 Deer Lake Drive E., Floor
      3,  Jacksonville,  Florida 32246,  which owned  538,488.089 Class B shares
      (6.53% of the Class B shares  then  outstanding),  for the  benefit of its
      customers.

      Merrill Lynch Pierce  Fenner & Smith,  Inc. 4800 Deer Lake Drive E., Floor
      3,  Jacksonville,  Florida 32246,  which owned  220,345,313 Class C shares
      (12.94% of the Class C shares  then  outstanding),  for the benefit of its
      customers.

The Manager.  The Manager is  wholly-owned by Oppenheimer  Acquisition  Corp., a
holding company controlled by Massachusetts  Mutual Life Insurance Company.  The
Manager and the Fund have a Code of Ethics. It is designed to detect and prevent
improper personal trading by certain employees,  including  portfolio  managers,
that would compete with or take advantage of the Fund's portfolio  transactions.
Compliance with the Code of Ethics is carefully  monitored and strictly enforced
by the Manager.

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

    |X| The  Investment  Advisory  Agreement.  The Manager  provides  investment
advisory  and  management  services  to the Fund  under an  investment  advisory
agreement  between the Manager and the Fund. The Manager selects  securities for
the  Fund's  portfolio  and  handles  its day-to day  business.  That  agreement
requires the Manager,  at its expense,  to provide the Fund with adequate office
space,  facilities  and  equipment.  It also requires the Manager to provide and
supervise the activities of all  administrative  and clerical personnel required
to   provide   effective   corporate   administration   for  the   Fund.   Those
responsibilities include the compilation and maintenance of records with respect
to the Fund's operations,  the preparation and filing of specified reports,  and
the  composition of proxy materials and  registration  statements for continuous
public sale of shares of the Fund.

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

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

    The agreement permits the Manager to act as investment adviser for any other
person, firm or corporation and to use the name "Oppenheimer" in connection with
other investment companies for which it may act as investment adviser or general
distributor.  If the Manager  shall no longer act as  investment  adviser to the
Fund, the Manager may withdraw the Fund's right to use the name "Oppenheimer" as
part of its name.

Brokerage Policies of the Fund

Brokerage Provisions of the Investment Advisory Agreement.  One of the duties of
the Manager under the investment advisory agreement is to buy and sell portfolio
securities for the Fund. The investment advisory agreement allows the Manager to
use  broker-dealers  to effect  the  Fund's  portfolio  transactions.  Under the
agreement,  the Manager may employ those broker-dealers  (including "affiliated"
brokers,  as that term is defined in the  Investment  Company Act) that,  in the
Manager's best judgment based on all relevant factors, will implement the Fund's
policy to obtain,  at  reasonable  expense,  the "best  execution"  of portfolio
transactions.  "Best execution"  refers to prompt and reliable  execution at the
most  favorable  price  obtainable.   The  Manager  need  not  seek  competitive
commission bidding. However, the Manager is expected to minimize the commissions
paid to the extent  consistent  with the  interest  and  policies of the Fund as
established by its Board of Trustees.

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

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

    Most securities purchases made by the Fund are in principal  transactions at
net prices.  The Fund  usually  deals  directly  with the selling or  purchasing
principal or market maker without incurring charges for the services of a broker
on its behalf unless the Manager determines that a better price or execution may
be obtained  by using the  services  of a broker.  Therefore,  the Fund does not
incur  substantial   brokerage  costs.   Portfolio   securities  purchased  from
underwriters  include  a  commission  or  concession  paid by the  issuer to the
underwriter in the price of the security.  Portfolio  securities  purchased from
dealers include a spread between the bid and asked price.

    The Fund seeks to obtain  prompt  execution of orders at the most  favorable
net prices. In an option  transaction,  the Fund ordinarily uses the same broker
for the purchase or sale of the option and any  transaction in the investment to
which the option relates. When possible, the Manager tries to combine concurrent
orders to  purchase or sell the same  security by more than one of the  accounts
managed by the Manager or its affiliates.  The transactions under those combined
orders are averaged as to price and allocated in accordance with the purchase or
sale orders actually placed for each account.

    The investment  advisory agreement permits the Manager to allocate brokerage
for research services. The research services provided by a particular broker may
be useful  only to one or more of the  advisory  accounts of the Manager and its
affiliates. Investment research received by the Manager for the commissions paid
by those  other  accounts  may be useful both to the Fund and one or more of the
Manager's other accounts.  Investment  research  services may be supplied to the
Manager by a third party at the  instance of a broker  through  which trades are
placed.  Investment  research  services  include  information  and  analyses  on
particular  companies and  industries  as well as market or economic  trends and
portfolio  strategy,  market quotations for portfolio  evaluations,  information
systems,  computer  hardware and similar  products and  services.  If a research
service also assists the Manager in a non-research capacity (such as bookkeeping
or other administrative  functions),  then only the percentage or component that
provides assistance to the Manager in the investment decision-making process may
be paid in commission dollars.

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

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

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

Distribution and Service Plans

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

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

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

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

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

    Unless a plan is terminated as described below, the plan continues in effect
from year to year, but only if the Fund's Board of Trustees and its  Independent
Trustees specifically vote annually to approve its continuance. Approval must be
by a vote  cast in  person  at a meeting  called  for the  purpose  of voting on
continuing  the  plan.  A plan  may be  terminated  at any time by the vote of a
majority  of the  Independent  Trustees  or by the  vote  of  the  holders  of a
"majority" (as defined in the Investment  Company Act) of the outstanding shares
of that class.

    The Board and the Independent  Trustees must approve all material amendments
to a plan. An amendment to increase materially the amount of payments to be made
under the plan must be approved  by  shareholders  of the class  affected by the
amendment.  Because  Class B shares  automatically  convert  into Class A shares
after six years,  the Fund must obtain the  approval of both Class A and Class B
shareholders for an amendment to the Class A plan that would materially increase
the amount to be paid under that plan. That approval must be by a "majority" (as
defined  in the  Investment  Company  Act) of the shares of each  class,  voting
separately by Class.
    While the plans are in  effect,  the  Treasurer  of the Fund  shall  provide
separate  written  reports on the plans to the Fund's Board of Trustees at least
quarterly  for its review.  The reports  shall detail the amount of all payments
made  under a plan and the  purpose  for which the  payments  were  made.  Those
reports are subject to the review and  approval of the  Independent  Trustees in
the exercise of their fiduciary duty.

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

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

    |_|  Class A  Service  Plan  Fees.  Under  the  Class A  service  plan,  the
Distributor  currently  uses the fees it receives  from the Fund to pay brokers,
dealers and other financial  institutions (they are referred to as "recipients")
for personal  services and account  maintenance  services they provide for their
customers who hold Class A shares. The services include, among others, answering
customer  inquiries about the Fund,  assisting in  establishing  and maintaining
accounts in the Fund, making the Fund's investment plans available and providing
other services at the request of the Fund or the  Distributor.  The  Distributor
makes  payments  to plan  recipients  quarterly  at an annual rate not to exceed
0.25% of the  average  annual net assets of Class A shares  acquired on or after
April 1, 1991, held in accounts of the service providers or their customers. The
rate is 0.15%  for  average  annual  net  assets  represented  by Class A shares
acquired before April 1, 1991.

    For the fiscal year ended July 31, 1999, payments under the Plan for Class A
shares  totaled  $1,290,905,  all  of  which  was  paid  by the  Distributor  to
recipients. That included $109,431 paid to an affiliate of the Distributor.  Any
unreimbursed  expenses the Distributor incurs with respect to Class A shares for
any fiscal year may not be recovered in subsequent  years.  The  Distributor may
not use  payments  received  under the  Class A plan to pay any of its  interest
expenses, carrying charges, other financial costs, or allocation of overhead.

    |_| Class B and Class C Service and Distribution Plan Fees. Under each plan,
service fees and distribution  fees are computed on the average of the net asset
value of  shares in the  respective  class,  determined  as of the close of each
regular  business day during the period.  The Class B and Class C plans  provide
for the Distributor to be compensated at a flat rate,  whether the Distributor's
distribution  expenses  are more or less than the amounts paid by the Fund under
the  plans  during  that  period.  The  Class B and  Class C  plans  permit  the
Distributor to retain both the asset-based  sales charges and the service fee on
shares or to pay  recipients  the  service  fee on a  quarterly  basis,  without
payment in advance.

    The Distributor presently intends to pay recipients the service fee on Class
B and Class C shares in advance  for the first year the shares are  outstanding.
After the first year shares are  outstanding,  the  Distributor  makes  payments
quarterly on those shares.  The advance  payment is based on the net asset value
of shares  sold.  Shares  purchased  by  exchange  do not qualify for an advance
service fee payment.  If Class B or Class C shares are redeemed during the first
year after their  purchase,  the  recipient  of the service fees on those shares
will be  obligated  to repay the  Distributor  a pro rata portion of the advance
payment made on those shares.

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

    The asset-based  sales charge on Class B and Class C shares allows investors
to buy shares without a front-end sales charge while allowing the Distributor to
compensate dealers that sell those shares. The Distributor's  actual expenses in
selling  Class B and Class C shares may be more than the  payments  it  receives
from contingent deferred sales charges collected on redeemed shares and from the
Fund  under  the  plans.  The Fund  pays the  asset-based  sales  charge  to the
Distributor  for its  services  rendered  in  distributing  Class B and  Class C
shares.  The  payments  are  made to the  Distributor  in  recognition  that the
Distributor:
    |_|pays sales  commissions to authorized  brokers and dealers at the time of
       sale and pays service fees as described in the Prospectus,
    |_|may  finance  payment  of sales  commissions  and/or  the  advance of the
       service fee payment to  recipients  under the plans,  or may provide such
       financing from its own resources or from the resources of an affiliate,
    |_|    employs personnel to support distribution of shares, and
    |_|    bears the costs of sales  literature,  advertising and  prospectuses
       (other than those furnished to current shareholders) and state "blue sky"
       registration fees and certain other distribution expenses.

    The Distributor's  actual expenses in selling Class B and Class C shares may
be more than the payments it receives from the contingent deferred sales charges
collected  on redeemed  shares and from the Fund under the plans.  If either the
Class B or Class C plan is  terminated  by the Fund,  the Board of Trustees  may
allow the Fund to  continue  payments  of the  asset-based  sales  charge to the
Distributor for distributing shares before the plan was terminated.

Performance of the Fund

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

    The Fund's  illustrations  of its performance  data in  advertisements  must
comply  with  rules of the  Securities  and  Exchange  Commission.  Those  rules
describe  the  types of  performance  data  that may be used and how it is to be
calculated.  In general,  any  advertisement by the Fund of its performance data
must include the average annual total returns for the advertised class of shares
of the Fund.  Those  returns must be shown for the 1, 5 and 10-year  periods (or
the life of the class,  if less) ending as of the most recently  ended  calendar
quarter prior to the  publication  of the  advertisement  (or its submission for
publication).  Certain types of yields may also be shown, provided that they are
accompanied by standardized average annual total returns.

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

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

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

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

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

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

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

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

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

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

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

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

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

    The  tax-equivalent  yield may be used to compare  the tax effects of income
derived  from the Fund with income  from  taxable  investments  at the tax rates
stated.  Your tax bracket is determined by your Federal  taxable income (the net
amount  subject to Federal  income tax after  deductions  and  exemptions).  The
tax-equivalent  yield table  assumes  that the  investor is taxed at the highest
bracket, regardless of whether a switch to non-taxable investments would cause a
lower bracket to apply.

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

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

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

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

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

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

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

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

    |_| Lipper  Rankings.  From time to time the Fund may publish the ranking of
the  performance of its Class A, Class B or Class C shares by Lipper  Analytical
Services, Inc. ("Lipper"). Lipper is a widely-recognized independent mutual fund
monitoring  service.  Lipper  monitors the  performance of regulated  investment
companies,  including the Fund, and ranks their  performance for various periods
based on categories  relating to investment  objectives.  The performance of the
Fund is ranked by Lipper  against all other general  municipal  bond funds.  The
Lipper  performance  rankings  are  based  on total  returns  that  include  the
reinvestment of capital gain  distributions and income dividends but do not take
sales charges or taxes into  consideration.  Lipper also publishes  "peer-group"
indices of the  performance  of all mutual funds in a category  that it monitors
and averages of the performance of the funds in particular categories.

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

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

    The Fund may also compare its total return ranking to that of other funds in
its Morningstar  category.  In addition to its star ratings.  Those total return
rankings are percentage from one percent to one hundred percent and are not risk
adjusted. For example, if a fund is in the 94th percentile,  that means that 94%
of the funds in the same category performed better than it did.

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

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

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


ABOUT YOUR ACCOUNT

How to Buy Shares

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

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

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

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

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

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

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

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

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

    A Letter  enables  an  investor  to  count  the  Class A and  Class B shares
purchased  under the Letter to obtain the reduced sales charge rate on purchases
of Class A shares of the Fund (and other  Oppenheimer  funds) that applies under
the Right of Accumulation to current purchases of Class A shares.  Each purchase
of Class A shares  under the Letter  will be made at the public  offering  price
(including  the sales  charge)  that  applies to a single  lump-sum  purchase of
shares in the amount intended to be purchased under the Letter.

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

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

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

    |_| Terms of Escrow That Apply to Letters of Intent.

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

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

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

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

    5. The shares  eligible  for  purchase  under the Letter (or the  holding of
which may be counted toward completion of a Letter) include:

(a)       Class A shares  sold with a  front-end  sales  charge or  subject to a
          Class A contingent deferred sales charge,
(b)       Class B shares  of  other  Oppenheimer  funds  acquired  subject  to a
          contingent deferred sales charge, and
(c)       Class A or Class B shares  acquired  by exchange of either (1) Class A
          shares  of one of the  other  Oppenheimer  funds  that  were  acquired
          subject to a Class A initial or  contingent  deferred  sales charge or
          (2)  Class B shares of one of the other  Oppenheimer  funds  that were
          acquired subject to a contingent deferred sales charge.

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

Asset Builder Plans.  To establish an Asset Builder Plan to buy shares  directly
from a bank  account,  you must  enclose a check  (the  minimum  is $25) for the
initial purchase with your  application.  Shares purchased by Asset Builder Plan
payments  from bank  accounts  are subject to the  redemption  restrictions  for
recent purchases described in the Prospectus.  Asset Builder Plans are available
only if your bank is an ACH member.  Asset  Builder Plans may not be used to buy
shares for  OppenheimerFunds-employer-sponsored  qualified  retirement accounts.
Asset Builder Plans also enable shareholders of Oppenheimer Cash Reserves to use
their account in that fund to make monthly  automatic  purchases of shares of up
to four other Oppenheimer funds.

    If you make  payments  from your bank to purchase  shares of the Fund,  your
bank account will be debited automatically. Normally, the debit will be made two
business days prior to the  investment  dates you selected on your  Application.
Neither the  Distributor,  the Transfer  Agent nor the Fund shall be responsible
for  any  delays  in   purchasing   shares   that  result  from  delays  in  ACH
transmissions.

    Before you establish Asset Builder payments,  you should obtain a prospectus
of the selected  fund(s) from your financial  advisor (or the  Distributor)  and
request an application from the Distributor. Complete the application and return
it.  You may  change  the  amount  of your  Asset  Builder  payment  or your can
terminate  these  automatic  investments  at any time by writing to the Transfer
Agent. The Transfer Agent requires a reasonable  period  (approximately 10 days)
after  receipt of your  instructions  to implement  them.  The Fund reserves the
right to amend, suspend, or discontinue offering Asset Builder plans at any time
without prior notice.

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

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

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

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

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

    |_|  Allocation  of Expenses.  The Fund pays  expenses  related to its daily
operations,  such as custodian fees, trustees' fees, transfer agency fees, legal
fees and auditing  costs.  Those  expenses are paid out of the Fund's assets and
are not paid directly by  shareholders.  However,  those expenses reduce the net
asset  value of shares,  and  therefore  are  indirectly  borne by  shareholders
through their investment.

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

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

Determination  of Net Asset Values Per Share.  The net asset values per share of
each class of shares of the Fund are  determined  as of the close of business of
The New York Stock Exchange on each day that the Exchange is open. It is done by
dividing  the value of the Fund's net assets  attributable  to that class by the
number of shares of that  class  that are  outstanding.  The  Exchange  normally
closes at 4:00  P.M.,  New York time,  but may close  earlier on some other days
(for  example,  in case of  weather  emergencies  or on days  falling  before  a
holiday).  The Exchange's most recent annual  announcement  (which is subject to
change)  states that it will close on New Year's Day,  Martin  Luther King,  Jr.
Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence Day, Labor Day,
Thanksgiving Day and Christmas Day. It may also close on other days.

    Dealers  other than  Exchange  members  may  conduct  trading  in  municipal
securities on days on which the Exchange is closed (including  weekends and U.S.
holidays) or after 4:00 P.M. on a regular  business day.  Because the Fund's net
asset values will not be calculated  on those days,  the Fund's net asset values
per share may be significantly  affected on such days when  shareholders may not
purchase or redeem shares.

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

    |_|Long-term  debt  securities  having a remaining  maturity in excess of 60
       days are valued  based on the mean  between the "bid" and "asked"  prices
       determined by a portfolio pricing service approved by the Fund's Board of
       Trustees or obtained by the Manager from two active  market makers in the
       security on the basis of reasonable inquiry.
    |_|The  following  securities  are valued at the mean  between the "bid" and
       "asked"  prices  determined by a pricing  service  approved by the Fund's
       Board of  Trustees or  obtained  by the  Manager  from two active  market
       makers  in the  security  on the  basis of  reasonable  inquiry:  (1)debt
       instruments that have a maturity of more than 397 days when
          issued,
       (2)debt  instruments  that had a maturity of 397 days or less when issued
          and have a remaining maturity of more than 60 days, and
       (3)non-money  market debt  instruments that had a maturity of 397 days or
          less when  issued and which have a  remaining  maturity  of 60 days or
          less.
    |_|         The  following  securities  are  valued at cost,  adjusted  for
       amortization of premiums and accretion of discounts:
       (1)money  market debt  securities  held by a non-money  market fund that
          had a maturity of less than 397 days when issued that have a remaining
          maturity of 60 days or less, and
       (2)debt  instruments  held by a money  market  fund that have a remaining
          maturity of 397 days or less.
    |_|Securities not having  readily-available  market quotations are valued at
       fair value determined under the Board's procedures.

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

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

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

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

How to Sell Shares

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

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

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

(1)     for  individual  accounts,  represents  that  they  are  the  registered
        owner(s) of the shares of the Fund in that account;
(2)     for accounts for corporations,  partnerships, trusts and other entities,
        represents that they are an officer,  general partner,  trustee or other
        fiduciary or agent,  as applicable,  duly authorized to act on behalf of
        such registered owner(s);
(3)     authorizes  the Fund,  its Transfer Agent and any bank through which the
        Fund's  drafts  (checks) are payable to pay all checks drawn on the Fund
        account of such  person(s)  and to redeem a sufficient  amount of shares
        from that account to cover payment of each check;
(4)     specifically  acknowledges  that if they  choose to permit  checks to be
        honored if there is a single  signature  on checks drawn  against  joint
        accounts,  or accounts for corporations,  partnerships,  trusts or other
        entities,  the  signature  of any  one  signatory  on a  check  will  be
        sufficient to authorize  payment of that check and  redemption  from the
        account,  even if that account is  registered  in the names of more than
        one  person  or  more  than  one  authorized  signature  appears  on the
        Checkwriting card or the Application, as applicable;
(5)     understands that the Checkwriting privilege may be terminated or amended
        at any time by the Fund and/or the Fund's bank; and
(6)     acknowledges  and agrees that  neither the Fund nor its bank shall incur
        any  liability  for  that  amendment  or  termination  of   checkwriting
        privileges or for redeeming shares to pay checks reasonably  believed by
        them to be genuine,  or for returning or not paying checks that have not
        been accepted for any reason.

Reinvestment  Privilege.  Within six months of a redemption,  a shareholder may
reinvest all or part of the redemption proceeds of:
    |_| Class A shares that you purchased  subject to an initial sales charge or
        Class A shares on which a contingent deferred sales charge was paid, or
    |_| Class B shares  that were  subject  to the Class B  contingent  deferred
        sales charge when redeemed.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

How to Exchange Shares

    As stated in the  Prospectus,  shares of a particular  class of  Oppenheimer
funds having more than one class of shares may be  exchanged  only for shares of
the same class of other Oppenheimer funds. Shares of Oppenheimer funds that have
a single class without a class  designation are deemed "Class A" shares for this
purpose.  You can obtain a current list showing  which funds offer which classes
by calling the Distributor at 1-800-525-7048.

    |_|All of the  Oppenheimer  funds  currently  offer  Class A, B and C shares
       except  Oppenheimer  Money Market  Fund,  Inc.,  Centennial  Money Market
       Trust,   Centennial  Tax  Exempt  Trust,   Centennial  Government  Trust,
       Centennial  New York Tax Exempt Trust,  Centennial  California Tax Exempt
       Trust, and Centennial America Fund, L.P., which only offer Class A
       shares.
    |_|Oppenheimer Main Street  California  Municipal Fund currently offers only
       Class A and Class B shares.
    |_|Class B and Class C shares of  Oppenheimer  Cash  Reserves are  generally
       available  only by  exchange  from the  same  class  of  shares  of other
       Oppenheimer funds or through OppenheimerFunds-sponsored 401 (k) plans.
    |_|Only certain  Oppenheimer  funds currently offer Class Y shares.  Class Y
       shares of Oppenheimer  Real Asset Fund may not be exchanged for shares of
       any other fund.
    |_|Class  M  shares  of  Oppenheimer  Convertible  Securities  Fund  may  be
       exchanged only for Class A shares of other  Oppenheimer  funds.  They may
       not be  acquired  by  exchange  of  shares  of  any  class  of any  other
       Oppenheimer  funds except Class A shares of Oppenheimer Money Market Fund
       or Oppenheimer Cash Reserves acquired by exchange of Class M shares.
    |_|Class A shares of Senior Floating Rate Fund are not available by exchange
       of Class A shares of other  Oppenheimer  funds.  Class A shares of Senior
       Floating Rate Fund that are exchanged for shares of the other Oppenheimer
       funds may not be  exchanged  back for  Class A shares of Senior  Floating
       Rate Fund.
    |_|Class X shares of Limited Term New York  Municipal  Fund can be exchanged
       only for Class B shares of other  Oppenheimer  funds and no exchanges may
       be made to Class X shares.
    |_|Shares of Oppenheimer Capital  Preservation Fund may not be exchanged for
       shares of Oppenheimer Money Market Fund, Inc.,  Oppenheimer Cash Reserves
       or Oppenheimer Limited-Term Government Fund. Only participants in certain
       retirement plans may purchase shares of Oppenheimer Capital  Preservation
       Fund,  and  only  those   participants   may  exchange  shares  of  other
       Oppenheimer funds for shares of Oppenheimer Capital Preservation Fund.

    Class A shares of Oppenheimer  funds may be exchanged at net asset value for
shares of any money market fund offered by the Distributor.  Shares of any money
market fund  purchased  without a sales  charge may be  exchanged  for shares of
Oppenheimer  funds offered with a sales charge upon payment of the sales charge.
They may also be used to  purchase  shares of  Oppenheimer  funds  subject  to a
contingent deferred sales charge.

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

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

    The Fund may amend, suspend or terminate the exchange privilege at any time.
Although the Fund may impose these changes at any time, it will provide you with
notice of those changes  whenever it is required to do so by applicable  law. It
may be  required  to provide 60 days  notice  prior to  materially  amending  or
terminating  the  exchange  privilege.  That 60 day  notice is not  required  in
extraordinary circumstances.

    |_| How Exchanges Affect  Contingent  Deferred Sales Charges.  No contingent
deferred  sales charge is imposed on exchanges of shares of any class  purchased
subject to a contingent  deferred  sales  charge.  However,  when Class A shares
acquired  by  exchange of Class A shares of other  Oppenheimer  funds  purchased
subject to a Class A contingent  deferred  sales  charge are redeemed  within 18
months of the end of the calendar month of the initial purchase of the exchanged
Class A shares,  the Class A contingent  deferred sales charge is imposed on the
redeemed  shares.  The Class B  contingent  deferred  sales charge is imposed on
Class B shares  acquired by exchange if they are redeemed  within 6 years of the
initial  purchase  of the  exchanged  Class B  shares.  The  Class C  contingent
deferred sales charge is imposed on Class C shares  acquired by exchange if they
are redeemed  within 12 months of the initial  purchase of the exchanged Class C
shares.

    When  Class B or Class C shares  are  redeemed  to effect an  exchange,  the
priorities described in "How To Buy Shares" in the Prospectus for the imposition
of the Class B or the Class C contingent  deferred sales charge will be followed
in determining  the order in which the shares are exchanged.  Before  exchanging
shares,  shareholders  should take into  account how the exchange may affect any
contingent  deferred  sales  charge  that  might be  imposed  in the  subsequent
redemption of remaining shares.

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

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

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

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

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

Dividends, Capital Gains and Taxes

Dividends and Distributions.  Dividends will be payable on shares held of record
at the time of the previous  determination  of net asset value,  or as otherwise
described in "How to Buy Shares."  Daily  dividends will not be declared or paid
on newly purchased  shares until such time as Federal Funds (funds credited to a
member  bank's  account at the  Federal  Reserve  Bank) are  available  from the
purchase  payment for such  shares.  Normally,  purchase  checks  received  from
investors  are  converted  to Federal  Funds on the next  business  day.  Shares
purchased through dealers or brokers normally are paid for by the third business
day following the placement of the purchase order.

    Shares  redeemed  through  the  regular  redemption  procedure  will be paid
dividends  through  and  including  the day on which the  redemption  request is
received by the  Transfer  Agent in proper form.  Dividends  will be declared on
shares  repurchased  by a dealer or broker for three business days following the
trade  date (that is, up to and  including  the day prior to  settlement  of the
repurchase).  If all shares in an account are redeemed, all dividends accrued on
shares  of the  same  class  in the  account  will be  paid  together  with  the
redemption proceeds.

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

    Dividends,  distributions  and the proceeds of the redemption of Fund shares
represented  by checks  returned to the Transfer  Agent by the Postal Service as
undeliverable  will be invested in shares of Oppenheimer Money Market Fund, Inc.
Reinvestment  will be made as  promptly  as  possible  after the  return of such
checks  to the  Transfer  Agent,  to  enable  the  investor  to earn a return on
otherwise  idle funds.  Unclaimed  accounts may be subject to state  escheatment
laws, and the Fund and the Transfer Agent will not be liable to  shareholders or
their representatives for compliance with those laws in good faith.

    The amount of a distribution paid on a class of shares may vary from time to
time depending on market  conditions,  the composition of the Fund's  portfolio,
and expenses  borne by the Fund or borne  separately  by a class.  Dividends are
calculated  in the same manner,  at the same time and on the same day for shares
of each class. However,  dividends on Class B and Class C shares are expected to
be lower  than  dividends  on Class A shares.  That is due to the  effect of the
asset-based  sales charge on Class B and Class C shares.  Those  dividends  will
also  differ in amount as a  consequence  of any  difference  in net asset value
among Class A, Class B and Class C shares.

Tax  Status of the  Fund's  Dividends  and  Distributions.  The Fund  intends to
qualify  under  the  Internal  Revenue  Code  during  each  fiscal  year  to pay
"exempt-interest dividends" to its shareholders.  Exempt-interest dividends that
are  derived  from  net  investment  income  earned  by the  Fund  on  municipal
securities  will be  excludable  from gross income of  shareholders  for Federal
income tax purposes.

    Net investment  income includes the allocation of amounts of income from the
municipal  securities in the Fund's  portfolio that are free from Federal income
taxes.  This  allocation  will be made by the use of one  designated  percentage
applied  uniformly to all income dividends paid during the Fund's tax year. That
designation  will  normally be made  following the end of each fiscal year as to
income dividends paid in the prior year. The percentage of income  designated as
tax-exempt  may  substantially  differ from the  percentage of the Fund's income
that was tax-exempt for a given period.

    A portion of the  exempt-interest  dividends paid by the Fund may be an item
of tax preference for shareholders  subject to the alternative  minimum tax. The
amount of any dividends attributable to tax preference items for purposes of the
alternative  minimum tax will be identified  when tax information is distributed
by the Fund.

    A  shareholder  receiving a dividend from income earned by the Fund from one
or more of the  following  sources  treats the  dividend  as a receipt of either
ordinary  income or long-term  capital gain in the  computation of gross income,
regardless of whether the dividend is reinvested:  (1) certain taxable temporary
investments (such as certificates of deposit,
        repurchase  agreements,  commercial  paper and  obligations of the U.S.
        government, its agencies and instrumentalities);
(2) income from securities  loans;  (3) income or gains from options or futures;
or (4) an excess of net short-term capital gain over net long-term capital loss
        from the Fund.

    The  Fund's  dividends  will  not be  eligible  for  the  dividends-received
deduction for  corporations.  Shareholders  receiving  Social Security  benefits
should be aware  that  exempt-interest  dividends  are a factor  in  determining
whether such  benefits  are subject to Federal  income tax.  Losses  realized by
shareholders  on the  redemption  of Fund  shares  within six months of purchase
(which period may be shortened by  regulation)  will be  disallowed  for Federal
income tax purposes to the extent of exempt-interest  dividends received on such
shares.

    If the Fund qualifies as a "regulated investment company" under the Internal
Revenue Code, it will not be liable for Federal  income taxes on amounts paid by
it as dividends and distributions.  That qualification enables the Fund to "pass
through" its income and realized capital gains to shareholders without having to
pay tax on them.  The Fund  qualified as a regulated  investment  company in its
last fiscal year and intends to qualify in future years,  but reserves the right
not to qualify.  The Internal Revenue Code contains a number of complex tests to
determine  whether the Fund qualifies.  The Fund might not meet those tests in a
particular  year.  If it does not  qualify,  the Fund  will be  treated  for tax
purposes  as an  ordinary  corporation  and will  receive no tax  deduction  for
payments of dividends and distributions made to shareholders.

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

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

Additional Information About the Fund

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

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

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

                 MUNICIPAL BOND RATINGS DEFINITIONS

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

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

Long-Term Bond Ratings

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Long-Term Credit Ratings

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

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

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

BBB: Bonds rated BBB exhibit adequate protection  parameters.  However,  adverse
economic  conditions  or  changing  circumstances  are more  likely to lead to a
weakened  capacity  of the  obligor  to meet  its  financial  commitment  on the
obligation.  Bonds rated BB, B, CCC, CC and C are regarded as having significant
speculative characteristics.  BB indicates the least degree of speculation and C
the highest. While such obligations will likely have some quality and protective
characteristics,  these  may be  outweighed  by  large  uncertainties  or  major
exposures to adverse conditions.

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

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

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

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

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

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

The  ratings  from AA to CCC may be  modified  by the  addition of a plus (+) or
minus (-) sign to show relative standing within the major rating categories. The
"r" symbol is attached to the ratings of instruments with significant  noncredit
risks.

Short-Term Issue Credit Ratings

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

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

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

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

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

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

Fitch IBCA, Inc.

International Long-Term Credit Ratings

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

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

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

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

Speculative Grade:

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

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

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

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

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

International Short-Term Credit Ratings

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

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

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

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

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

D:   Default. Denotes actual or imminent payment default.

Duff & Phelps Credit Rating Co. Ratings

Long-Term Debt and Preferred Stock

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

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

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

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

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

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

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

DD:  Defaulted  debt  obligations.  Issuer failed to meet  scheduled  principal
and/or interest payments.

DP:  Preferred stock with dividend arrearages.

Short-Term Debt:

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

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

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

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

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

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

                                   Appendix C

        OppenheimerFunds Special Sales Charge Arrangements and Waivers

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

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

    For  the  purposes  of  some  of  the  waivers  described  below  and in the
Prospectus and Statement of Additional Information of the applicable Oppenheimer
funds,  the term  "Retirement  Plan" refers to the following types of plans: (1)
plans qualified under Sections 401(a) or 401(k) of the Internal Revenue
       Code,
(2) non-qualified  deferred  compensation plans, (3) employee benefit plans3 (4)
Group  Retirement  Plans4 (5) 403(b)(7)  custodial  plan accounts (6) Individual
Retirement Accounts ("IRAs"), including traditional IRAs, Roth
       IRAs, SEP-IRAs, SARSEPs or SIMPLE plans

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

Waivers  that apply at the time shares are  redeemed  must be  requested  by the
shareholder and/or dealer in the redemption request.
--------------
1. Certain  waivers  also  apply to Class M shares  of  Oppenheimer  Convertible
   Securities Fund.
2. In the case of Oppenheimer Senior Floating Rate Fund, a  continuously-offered
   closed-end  fund,  references to contingent  deferred  sales charges mean the
   Fund's  Early  Withdrawal   Charges  and  references  to  "redemptions"  mean
   "repurchases" of shares.
3. An "employee  benefit plan" means any plan or arrangement,  whether or not it
   is "qualified" under the Internal Revenue Code, under which Class A shares of
   an  Oppenheimer  fund  or  funds  are  purchased  by  a  fiduciary  or  other
   administrator  for the account of participants  who are employees of a single
   employer or of affiliated employers.  These may include, for example, medical
   savings accounts, payroll deduction plans or similar plans. The fund accounts
   must be registered in the name of the fiduciary or  administrator  purchasing
   the shares for the benefit of participants in the plan.
4. The term  "Group  Retirement  Plan"  means  any  qualified  or  non-qualified
   retirement  plan  for  employees  of a  corporation  or sole  proprietorship,
   members and  employees of a partnership  or  association  or other  organized
   group of persons  (the  members of which may include  other  groups),  if the
   group has made special  arrangements  with the Distributor and all members of
   the group  participating  in (or who are eligible to participate in) the plan
   purchase  Class A shares  of an  Oppenheimer  fund or funds  through a single
   investment dealer,  broker or other financial  institution  designated by the
   group.  Such plans  include 457 plans,  SEP-IRAs,  SARSEPs,  SIMPLE plans and
   403(b) plans other than plans for public  school  employees.  The term "Group
   Retirement Plan" also includes  qualified  retirement plans and non-qualified
   deferred  compensation  plans  and IRAs  that  purchase  Class A shares of an
   Oppenheimer fund or funds through a single investment dealer, broker or other
   financial institution that has made special arrangements with the Distributor
   enabling  those  plans to  purchase  Class A shares  at net  asset  value but
   subject to the Class A contingent deferred sales charge.
I.  Applicability  of Class A  Contingent  Deferred  Sales  Charges  in Certain
Cases

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

    There is no initial  sales  charge on  purchases of Class A shares of any of
the Oppenheimer funds in the cases listed below. However, these purchases may be
subject to the Class A contingent  deferred  sales charge if redeemed  within 18
months of the end of the calendar month of their  purchase,  as described in the
Prospectus (unless a waiver described  elsewhere in this Appendix applies to the
redemption).  Additionally,  on shares  purchased  under these  waivers that are
subject to the Class A contingent  deferred sales charge,  the Distributor  will
pay the  applicable  commission  described  in the  Prospectus  under  "Class  A
Contingent Deferred Sales Charge."2 This waiver provision applies to:
    o   Purchases of Class A shares aggregating $1 million or more.
    o   Purchases  by a  Retirement  Plan  (other  than  an  IRA  or  403(b)(7)
        custodial plan) that:
(1) buys shares costing $500,000 or more, or
(2)        has, at the time of purchase, 100 or more eligible employees or total
           plan assets of $500,000 or more, or
(3)         certifies  to the  Distributor  that it projects to have annual plan
            purchases of $200,000 or more.
    o      Purchases  by an  OppenheimerFunds-sponsored  Rollover  IRA,  if  the
           purchases are made:
(1)        through a broker,  dealer, bank or registered investment adviser that
           has  made  special   arrangements  with  the  Distributor  for  those
           purchases, or
(2)        by a direct  rollover of a distribution  from a qualified  Retirement
           Plan if the administrator of that Plan has made special  arrangements
           with the Distributor for those purchases.
    o   Purchases  of Class A shares by  Retirement  Plans  that have any of the
        following record-keeping arrangements:
(1)        The record  keeping is  performed by Merrill  Lynch  Pierce  Fenner &
           Smith,  Inc.  ("Merrill  Lynch") on a daily  valuation  basis for the
           Retirement   Plan.   On  the  date  the  plan   sponsor   signs   the
           record-keeping  service  agreement with Merrill Lynch,  the Plan must
           have $3 million or more of its assets  invested in (a) mutual  funds,
           other  than  those   advised  or  managed  by  Merrill   Lynch  Asset
           Management,  L.P.  ("MLAM"),  that are made available under a Service
           Agreement  between  Merrill  Lynch and the  mutual  fund's  principal
           underwriter or distributor,  and (b) funds advised or managed by MLAM
           (the funds  described in (a) and (b) are  referred to as  "Applicable
           Investments").
(2) The  record  keeping  for  the  Retirement  Plan  is  performed  on a daily
           valuation  basis by a record  keeper  whose  services  are  provided
           under a contract  or  arrangement  between the  Retirement  Plan and
           Merrill  Lynch.  On the date  the  plan  sponsor  signs  the  record
           keeping  service  agreement with Merrill  Lynch,  the Plan must have
           $3 million  or more of its  assets  (excluding  assets  invested  in
           money market funds) invested in Applicable Investments.
(3)        The record  keeping for a Retirement  Plan is handled under a service
           agreement  with Merrill  Lynch and on the date the plan sponsor signs
           that  agreement,  the Plan  has 500 or more  eligible  employees  (as
           determined by the Merrill Lynch plan conversion manager).
    o   Purchases by a Retirement Plan whose record keeper had a cost-allocation
        agreement with the Transfer Agent on or before May 1, 1999.

    These  arrangements  also apply to  shareholders of the following funds when
they merged (were  reorganized)  into various  Oppenheimer funds on November 24,
1995:

 Quest  for  Value  U.S.  Government Quest   for   Value  New  York

                                     Tax-Exempt Fund

    All of the  funds  listed  above are  referred  to in this  Appendix  as the
"Former Quest for Value Funds." The waivers of initial and  contingent  deferred
sales charges  described in this Appendix apply to shares of an Oppenheimer fund
that are either:
    o acquired  by such  shareholder  pursuant  to an  exchange  of shares of an
      Oppenheimer fund that was one of the Former Quest for Value Funds or
    o purchased by such shareholder by exchange of shares of another Oppenheimer
      fund that were acquired  pursuant to the merger of any of the Former Quest
      for Value Funds into that other Oppenheimer fund on November 24, 1995.

A.  Reductions or Waivers of Class A Sales Charges.

    Reduced  Class A Initial  Sales  Charge  Rates for Certain  Former Quest for
Value Funds Shareholders.

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.  The rates in the
table apply if that Association  purchased shares of any of the Former Quest for
Value Funds or received a proposal to purchase such shares from OCC Distributors
prior to November 24, 1995.

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

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

    Purchases  made under this  arrangement  qualify for the lower of either 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 Right of Accumulation  described
in the applicable  fund's  Prospectus  and Statement of Additional  Information.
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
Distributor.

    Waiver of Class A Sales  Charges  for Certain  Shareholders.  Class A shares
purchased by the  following  investors are not subject to any Class A initial or
contingent deferred sales charges:
    o Shareholders 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  who  acquired  shares of any Former  Quest for Value Fund by
      merger of any of the portfolios of the Unified Funds.

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

    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.

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

    Waivers for  Redemptions of Shares  Purchased Prior to March 6, 1995. In the
following  cases,  the  contingent  deferred  sales  charge  will be waived  for
redemptions  of Class A, Class B or Class C shares of an  Oppenheimer  fund. The
shares must have been  acquired  by the merger of a Former  Quest for Value Fund
into the fund or by exchange  from an  Oppenheimer  fund that was a Former Quest
for Value Fund or into  which  such fund  merged.  Those  shares  must have been
purchased prior to March 6, 1995 in connection with:
    o 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
    o 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.

    Waivers for  Redemptions  of Shares  Purchased on or After March 6, 1995 but
Prior to November 24, 1995.  In the following  cases,  the  contingent  deferred
sales  charge  will be waived  for  redemptions  of Class A,  Class B or Class C
shares of an Oppenheimer  fund. The shares must have been acquired by the merger
of a  Former  Quest  for  Value  Fund  into  the  fund  or by  exchange  from an
Oppenheimer  fund  that was a Former  Quest For Value  Fund or into  which  such
Former Quest for Value Fund merged.  Those shares must have been purchased on or
after March 6, 1995, but prior to November 24, 1995:
    o 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);
    o 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
    o liquidation of a shareholder's account if the aggregate net asset value of
      shares  held in the  account  is less than the  required  minimum  account
      value.

    A  shareholder's  account will be credited with the amount of any contingent
deferred  sales charge paid on the redemption of any Class A, Class B or Class C
shares of the  Oppenheimer  fund  described  in this section if the proceeds are
invested  in the same Class of shares in that fund or another  Oppenheimer  fund
within 90 days after redemption.

V. Special Sales Charge  Arrangements for  Shareholders of Certain  Oppenheimer
Funds Who Were Shareholders of Coonecticut Mutual Investment Accounts, Inc.

The initial and  contingent  deferred  sale charge rates and waivers for Class A

section):

investment adviser to the Former Connecticut Mutual Funds:

                                     Account

A.  Prior Class A CDSC and Class A Sales Charge Waivers.

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

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

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

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

    o Class A Sales Charge Waivers.  Additional  Class A shares of a Fund may be
purchased  without a sales  charge,  by a person who was in one (or more) of the
categories  below and acquired Class A shares prior to March 18, 1996, and still
holds Class A shares:  (1) any  purchaser,  provided  the total  initial  amount
invested in the Fund or
        any one or more of the Former  Connecticut Mutual Funds totaled $500,000
        or more, including  investments made pursuant to the Combined Purchases,
        Statement of Intention and Rights of Accumulation  features available at
        the time of the initial  purchase and such  investment  is still held in
        one or more of the Former  Connecticut Mutual Funds or a Fund into which
        such Fund merged;
(2)     any  participant  in a qualified  plan,  provided that the total initial
        amount invested by the plan in the Fund or any one or more of the Former
        Connecticut Mutual Funds totaled $500,000 or more;
(3)     Directors  of the  Fund or any one or  more  of the  Former  Connecticut
        Mutual Funds and members of their immediate families;
(4)     employee  benefit  plans  sponsored  by  Connecticut   Mutual  Financial
        Services,   L.L.C.   ("CMFS"),  the  prior  distributor  of  the  Former
        Connecticut Mutual Funds, and its affiliated companies;
(5)     one or more  members of a group of at least 1,000  persons  (and persons
        who  are  retirees  from  such  group)  engaged  in a  common  business,
        profession,  civic or  charitable  endeavor or other  activity,  and the
        spouses  and minor  dependent  children of such  persons,  pursuant to a
        marketing program between CMFS and such group; and
(6)     an  institution  acting as a  fiduciary  on behalf of an  individual  or
        individuals,  if  such  institution  was  directly  compensated  by  the
        individual(s) for recommending the purchase of the shares of the Fund or
        any one or more of the Former  Connecticut  Mutual  Funds,  provided the
        institution had an agreement with CMFS.

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

      Additionally,  Class A shares of a Fund may be  purchased  without a sales
charge by any holder of a variable  annuity contract issued in New York State by
Connecticut  Mutual Life Insurance Company through the Panorama Separate Account
which is beyond the  applicable  surrender  charge  period and which was used to
fund a qualified plan, if that holder  exchanges the variable  annuity  contract
proceeds to buy Class A shares of the Fund.

B. Class A and Class B Contingent Deferred Sales Charge Waivers.

In addition to the waivers  set forth in the  Prospectus  and in this  Appendix,
above,  the contingent  deferred sales charge will be waived for  redemptions of
Class A and Class B shares of a Fund and  exchanges of Class A or Class B shares
of a Fund into  Class A or Class B shares of a Former  Connecticut  Mutual  Fund
provided  that  the  Class A or Class B shares  of the  Fund to be  redeemed  or
exchanged  were (i)  acquired  prior to March 18, 1996 or (ii) were  acquired by
exchange from an  Oppenheimer  fund that was a Former  Connecticut  Mutual Fund.

        employee benefit plans;
(5)     in  whole or in part,  in  connection  with  shares  sold to any  state,
        county,  or city,  or any  instrumentality,  department,  authority,  or

        paying a sales charge or commission  in connection  with the purchase of
        shares of any registered investment management company;
(6)     in  connection  with  the  redemption  of  shares  of the  Fund due to a

        annually; or
(9)     as  involuntary  redemptions  of shares by  operation  of law,  or under
        procedures  set forth in the Fund's  Articles  of  Incorporation,  or as
        adopted by the Board of Directors of the Fund.

INDEPENDENT AUDITORS' REPORT
--------------------------------------------------------------------------------
TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF
OPPENHEIMER INSURED MUNICIPAL FUND:

We have audited the accompanying statement of assets and liabilities,  including
the  statement of  investments,  of  Oppenheimer  Insured  Municipal  Fund as of
September 30, 1999, the related statement of operations for the year then ended,
the  statements of changes in net assets for the years ended  September 30, 1999
and  1998,  and the  financial  highlights  for the  period  October  1, 1994 to
September 30, 1999. 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  confirma-tion  of securities  owned as of
September 30, 1999, 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 Insured
Municipal  Fund as of September  30, 1999,  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 $18,619,633 or 14.31% of the
Fund's net assets as of September 30, 1999.

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

3.  Represents   securities  sold  under  Rule  144A,   which  are  exempt  from
registration under the Securities Act of 1933, as amended. These securities have
been  determined  to be  liquid  under  guidelines  established  by the Board of
Trustees.  These  securities  amount to  $4,040,800  or 3.11% of the  Fund's net
assets as of September 30, 1999.

AS OF SEPTEMBER  30, 1999,  SECURITIES  SUBJECT TO THE  ALTERNATIVE  MINIMUM TAX
AMOUNT TO $37,548,433 OR 28.86% OF THE FUND'S NET ASSETS.

NOTES TO FINANCIAL STATEMENTS

-------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer   Insured  Municipal  Fund  (the  Fund)  is  a  separate  series  of
Oppenheimer  Municipal  Fund,  a  diversified,  open-end  management  investment
company  registered  under the Investment  Company Act of 1940, as amended.  The
Fund's investment  objective is to provide a high level of current income exempt
from Federal income tax. The Fund's investment advisor is OppenheimerFunds, Inc.
(the  Manager).  The Fund  offers  Class A, Class B and Class C shares.  Class A
shares are sold with a front-end  sales charge on  investments up to $1 million.
Class B and Class C shares may be subject to a contingent  deferred sales charge
(CDSC).  All classes of shares have  identical  rights to  earnings,  assets and
voting  privileges,  except  that  each  class  has  its own  expenses  directly
attributable  to that class and exclusive  voting rights with respect to matters
affecting  that  class.  Classes A, B and C have  separate  distribution  and/or
service plans. Class B shares will  automatically  convert to Class A shares six
years after the date of  purchase.  The  following  is a summary of  significant
accounting policies consistently followed by the Fund.
-------------------------------------------------------------------------------
SECURITIES  VALUATION.  Portfolio  securities are valued at the close of the New
York Stock  Exchange on each trading day.  Listed and  unlisted  securities  for
which such  information is regularly  reported are valued at the last sale price
of the day or, in the  absence of sales,  at values  based on the closing bid or
the  last  sale  price  on the  prior  trading  day.  Long-term  and  short-term
"non-money  market" debt  securities are valued by a portfolio  pricing  service
approved by the Board of Trustees.  Such securities which cannot be valued by an
approved portfolio pricing service are valued using  dealer-supplied  valuations
provided the Manager is satisfied that the firm rendering the quotes is reliable
and  that  the  quotes  reflect  current  market  value,  or  are  valued  under
consistently  applied  procedures  established  by  the  Board  of  Trustees  to
determine  fair  value  in good  faith.  Short-term  "money  market  type"  debt
securities having a remaining maturity of 60 days or less are valued at cost (or
last  determined  market  value)  adjusted for  amortization  to maturity of any
premium or  discount.  Options are valued  based upon the last sale price on the
principal  exchange  on which the  option is traded  or, in the  absence  of any
transactions  that day, the value is based upon the last sale price on the prior
trading  date if it is within  the  spread  between  the  closing  bid and asked
prices. If the last sale price is outside the spread, the closing bid is used.
-------------------------------------------------------------------------------
ALLOCATION OF INCOME,  EXPENSES,  GAINS AND LOSSES. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated daily to
each  class  of  shares  based  upon  the  relative  proportion  of  net  assets
represented  by  such  class.  Operating  expenses  directly  attributable  to a
specific class are charged against the operations of that class.


<PAGE>
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
--------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES Continued

FEDERAL TAXES. The Fund intends to continue to comply with provisions of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to shareholders. Therefore, no federal
income or excise tax provision is required.
--------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date.
--------------------------------------------------------------------------------
CLASSIFICATION OF DISTRIBUTIONS TO SHAREHOLDERS. Net investment income (loss)
and net realized gain (loss) may differ for financial statement and tax
purposes. The character of distributions made during the year from net
investment income or net realized gains may differ from its ultimate
characterization for federal income tax purposes. Also, due to timing of
dividend distributions, the fiscal year in which amounts are distributed may
differ from the fiscal year in which the income or realized gain was recorded by
the Fund. The Fund adjusts the classification of distributions to shareholders
to reflect the differences between financial statement amounts and distributions
determined in accordance with income tax regulations. Accordingly, during the
year ended September 30, 1999, amounts have been reclassified to reflect a
decrease in paid-in capital of $28,550, an increase in overdistributed net
investment income of $77,464, and a decrease in accumulated net realized loss on
investments of $106,014.
--------------------------------------------------------------------------------
EXPENSE OFFSET ARRANGEMENTS. Expenses paid indirectly represent a reduction of
custodian fees for earnings on cash balances maintained by the Fund.
--------------------------------------------------------------------------------
OTHER.  Investment  transactions  are accounted  for as of trade date.  Original
issue  discount is accreted and premium is amortized in accordance  with federal
income tax  requirements.  For municipal bonds acquired after April 30, 1993, on
disposition or maturity,  taxable ordinary income is recognized to the extent of
the lesser of gain or market  discount  that would have accrued over the holding
period. Realized gains and losses on investments and unrealized appreciation and
depreciation are determined on an identified cost basis, which is the same basis
used for federal income tax purposes.

     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.

</TABLE>

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

28 OPPENHEIMER INSURED MUNICIPAL FUND
<PAGE>
--------------------------------------------------------------------------------
CLASS A SERVICE  PLAN  FEES.  Under the Class A service  plan,  the  Distributor
currently  uses the fees it receives  from the Fund to pay brokers,  dealers and
other financial institutions. The Class A service plan permits reimbursements to
the Distributor at a rate of up to 0.25% of average annual net assets of Class A
shares. The Distributor makes payments to plan recipients quarterly at an annual
rate not to exceed 0.25% of the average annual net assets  consisting of Class A
shares of the Fund. For the fiscal year ended September 30, 1999, payments under
the Class A Plan totaled  $245,096,  all of which was paid by the Distributor to
recipients.  That  included  $12,398 paid to an  affiliate of the  Distributor's
parent company. Any unreimbursed expenses the Distributor incurs with respect to
Class A shares in any fiscal year cannot be recovered in subsequent years.
--------------------------------------------------------------------------------
CLASS B AND CLASS C DISTRIBUTION AND SERVICE PLAN FEES. Under each plan, service
fees and distribution fees are computed on the average of the net asset value of
shares in the  respective  class,  determined  as of the  close of each  regular
business  day during the period.  The Class B and Class C plans  provide for the
Distributor  to  be  compensated  at a  flat  rate,  whether  the  Distributor's
distribution  expenses  are more or less than the amounts paid by the Fund under
the plan during the period for which the fee is paid.

     The Distributor retains the asset-based sales charge on Class B shares. The
Distributor  retains the  asset-based  sales charge on Class C shares during the
first year the shares are outstanding.  The asset-based sales charges on Class B
and Class C shares  allow  investors  to buy shares  without a  front-end  sales
charge while  allowing the  Distributor  to  compensate  dealers that sell those
shares.

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

     Distribution  fees paid to the Distributor for the year ended September 30,
1999, were as follows:

5. FUTURES CONTRACTS

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

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

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

     Securities  held  in  collateralized   accounts  to  cover  initial  margin
requirements   on  open  futures   contracts  are  noted  in  the  Statement  of
Investments.  The  Statement  of Assets and  Liabilities  reflects a  receivable
and/or payable for the daily mark to market for variation margin.

     Risks of entering into futures contracts (and related options) include the
possibility that there may be an illiquid market and that a change in the value
of the contract or option may not correlate with changes in the value of the
underlying securities.
--------------------------------------------------------------------------------
6. BANK BORROWINGS

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

     The Fund had borrowings outstanding of $800,000 at September 30, 1999.

DEAR SHAREHOLDER,
--------------------------------------------------------------------------------

In many ways,  the 1999  investment  environment  has, so far,  unfolded as many
expected  it would,  producing  both  attractive  opportunities  and  formidable
challenges for investors.

    On the economic front, early worries about the effects of global weakness in
the wake of last year's credit and currency crises have abated. Instead, as many
economies  around the world  begin to  strengthen,  concerns  now center  around
whether  the U.S.  economy  may be growing  too  quickly.  Throughout  the year,
consumers in the United States have continued to spend and borrow heavily,  more
than offsetting any temporary slowdown in the industrial and export sectors.

    The  economy's  strength has not gone  unnoticed  by the  nation's  monetary
policymakers.  In an effort to ward off  emerging  inflationary  pressures,  the
Federal Reserve Board increased short-term interest rates this past summer.

    Market  reaction to robust  economic  growth has been mixed.  The U.S.  bond
market has generally  declined,  as fixed income investors  became  increasingly
concerned about the effects of rising interest rates.

    In the stock market, the performance of large-capitalization  growth stocks,
which has  driven the  market's  advance  over the past few years,  has begun to
moderate, and many previously out-of-favor value-oriented, mid-cap and small-cap
stocks have rallied. At the same time, a healthy percentage of actively managed,
diversified  portfolios  have once again  begun to  outperform  unmanaged  stock
indices such as Standard & Poor's 500.

                                                                  (over, please)

                       3 Oppenheimer Municipal Bond Fund
<PAGE>


At OppenheimerFunds,  we applaud the Fed's pre-emptive strike against inflation.
In our view,  history has repeatedly  demonstrated that most financial assets do
best in a  low-inflation  environment.  What's more, we believe that the move to
higher interest rates should be temporary.

    One recent  development is quite  troublesome to us however:  the increasing
popularity of "day trading"  among  individuals  seeking to make fast money in a
volatile  stock  market.  In our opinion,  day trading is not  investing,  it is
gambling.  Experience  proves that  without  extensive  research  and  analysis,
attempting  to time  short-term  price swings is a fool's  errand.  Instead,  we
continue to  encourage  investors  to maintain a long-term  perspective  that is
measured in years, not days.

    Finally,  while we remain alert to the potential impact of the Y2K issue, we
are   encouraged   by  the  progress   made  in   addressing   the  matter.   At
OppenheimerFunds,  our shareholder accounting systems are already Y2K compliant,
and we have successfully  participated in all required  industry-wide  tests. We
intend to  continue  re-testing  our  systems in order to help  further  protect
against any potential  problems.  After all, whether in our computer  accounting
systems or the financial  markets,  managing  risk is an important  part of what
makes OppenheimerFunds The Right Way to Invest.

Sincerely,

/s/ BRIDGET A. MACASKILL

AN INTERVIEW WITH YOUR FUND'S MANAGER
--------------------------------------------------------------------------------

HOW DID OPPENHEIMER  MUNICIPAL BOND FUND PERFORM DURING THE ONE-YEAR PERIOD THAT
ENDED JULY 31, 1999?

We are generally  pleased with the Fund's  performance  over the fiscal year. We
attribute the Fund's  performance to our conservative  investment  strategy in a
rapidly changing investment  environment.  In fact, market conditions during the
final six  months of 1998 and the first  half of 1999  were,  in many  respects,
direct  opposites  of each  other.  The final six months of 1998 were  generally
characterized by recessionary  economic conditions throughout much of the world,
declining  interest  rates in the United  States and less  restrictive  monetary
policies  worldwide.  In  contrast,  the first  half of 1999 saw signs of global
economic  recovery,  rising domestic interest rates and,  ultimately,  a tighter
monetary policy in the United States.

HOW DID THESE ECONOMIC CONDITIONS AFFECT THE U.S. MUNICIPAL BOND MARKET?

In stark contrast to the volatile prices of U.S. Treasury securities,  municipal
bonds were generally stable  throughout the one-year  reporting  period.  In the
first half of the period,  global  economic  uncertainty  triggered a "flight to
quality" among U.S. and foreign investors. This created unprecedented demand for
U.S. Treasury securities,  driving their prices up and their yields down (prices
and yields move in opposite directions). However, because municipal bonds do not
provide tax advantages to foreign  investors,  municipals did not benefit to the
same extent. As a result,  U.S. Treasury securities  significantly  outperformed
triple-A rated municipal bonds with comparable maturities.

                        5 Oppenheimer Municipal Bond Fund

"MUNICIPAL BONDS ENDURED SIGNIFICANTLY LESS VOLATILITY THAN OTHER HIGH-QUALITY,
FIXED INCOME SECURITIES OVER THE PAST YEAR."

AN INTERVIEW WITH YOUR FUND'S MANAGER
--------------------------------------------------------------------------------

In the second half of the  reporting  period,  while  municipal  bonds  remained
stable, prices of U.S. Treasury securities declined sharply. As the economy grew
stronger, many investors regained their confidence and sold their Treasury bonds
in order to return to riskier  financial  assets  such as stocks  and  corporate
bonds.  Consequently,  municipal bonds  generally  provided higher total returns
than U.S. Treasuries.

    In our  opinion,  municipal  bonds'  relative  stability  is the  result  of
supply-and-demand  factors.  Strong  economic  conditions  in the United  States
reduced many states and municipalities' need to borrow,  leading to a diminished
supply of tax-exempt  bonds.  In fact,  approximately  23% fewer municipal bonds
were issued during the first six months of 1999 than in the same period one year
earlier.  Yet,  demand  remained high from  investors  seeking to minimize their
income tax liabilities.  This supply-and-demand  relationship helped support the
stability of municipal bond prices and yields.

DID YOU FIND COMPELLING VALUES IN THIS MARKET ENVIRONMENT?

Yes. In the fourth quarter of 1998, long-term,  tax-exempt municipal bond yields
were actually  slightly higher than yields of long-term,  taxable U.S.  Treasury
securities. In effect, most investors who purchased municipal bonds at that time
generally  received the tax  advantages  for free. By mid-1999,  municipal  bond
yields decreased to approximately 91% of comparable Treasury yields.  While this
represented a substantial narrowing of the yield relationship between tax-exempt
and taxable  bonds,  we believe that,  compared to historical  norms,  municipal
bonds continue to provide excellent after-tax values.

HOW DID YOU MANAGE THE FUND IN THIS ENVIRONMENT?

We  attempted to invest in  tax-exempt  securities  while  managing the risks of
changing interest rates. Throughout the one-year reporting period, we emphasized
those sectors of the municipal bond market that we expected to benefit most from
prevailing economic and market conditions.  Conversely,  we tried to avoid those
sectors that we believed would benefit  least.  This strategy led us to areas of
opportunity  such as  retirement  villages  and adult living  facilities.  These
residential housing projects have issued tax-exempt bonds to meet rising demands
of a growing  population of aging Americans who want amenities tailored to their
lifestyles.

    Our  strategy  also led us to avoid  certain  issuers,  such as health  care
facilities  that are  subject to  financial  pressures  because  of a  currently
unfavorable  regulatory  and  legislative  environment,  including  cutbacks  in
Medicaid and  Medicare.  We also tended to avoid bonds issued by utilities  that
are in the midst of industry-wide deregulation.

1. Total returns  include  changes in share price and  reinvestment of dividends
and capital gains  distributions  in a  hypothetical  investment for the periods
shown.  Class A returns  include the current  maximum  initial  sales  charge of
4.75%.  Class A shares were first publicly offered on 10/27/76.  Class B returns
include the  applicable  contingent  deferred sales charge of 5% (1-year) and 1%
(since  inception on 3/16/93).  Class C returns for the one-year  result include
the  contingent  deferred  sales  charge of 1%. Class C shares have an inception
date of 8/29/95. Class B and C shares are subject to an annual 0.75% asset-based
sales charge. An explanation of the different performance calculations is in the
Fund's prospectus.

AN INTERVIEW WITH YOUR FUND'S MANAGER
-------------------------------------------------------------------------------

In addition,  throughout the reporting  period,  we maintained a neutral average
duration--which  is a measure of sensitivity to changes in interest rates.  When
interest rates declined in 1998, our neutral  position  constrained  performance
slightly  compared to portfolios with longer durations.  However,  when interest
rates rose in 1999, our neutral  position  helped shelter the portfolio from the
brunt of the interest-rate  risks affecting investors who had previously adopted
a longer, more aggressive, duration strategy.

WHAT IS YOUR OUTLOOK FOR THE MUNICIPAL BOND MARKET AND THE FUND?

We remain  cautiously  optimistic.  First,  we believe that municipal  bonds are
attractively  valued  relative  to  comparable  taxable  securities,  and should
benefit as that relationship returns to more normal levels.  Second,  states and
municipalities  have  benefited  greatly  from the recent  strength  of the U.S.
economy,  which  has  enabled  many of them to put their  fiscal  houses in good
order. This should help reduce the risk of potential defaults.

2.  Standardized  yield is based on net investment  income for the 30-day period
ended July 31,  1999.  Falling  share  prices  will tend to  artificially  raise
yields.

On the other hand, we remain concerned about rising interest rates. Accordingly,
we intend to continue  to monitor the  economic  environment  carefully.  If the
economy  continues  to  grow  at an  unsustainable  rate,  we may  position  the
portfolio to reduce the adverse effects of potentially higher interest rates. We
believe that these  credit-conscious,  risk-averse  strategies make  Oppenheimer
Municipal Bond Fund an important part of The Right Way to Invest.

FUND PERFORMANCE
--------------------------------------------------------------------------------

HOW HAS THE FUND PERFORMED? Below is a discussion, by the Manager, of the Fund's
performance during its fiscal year ended July 31, 1999,  followed by a graphical
comparison of the Fund's performance to an appropriate broad-based market index.

    - MANAGEMENT'S DISCUSSION OF PERFORMANCE. During the Fund's fiscal year that
ended July 31, 1999,  Oppenheimer Municipal Bond Fund performed relatively well,
despite the fact that the overall bond market weakened considerably in 1999. The
weakness in the bond market  stemmed from signs of  continuing  strong  economic
growth,  which could cause  inflation to reemerge.  However,  the Fund benefited
from a reduced  supply of new tax-exempt  bond issues  relative to robust demand
from investors seeking to manage their income tax liabilities. This reduction in
issuance was primarily a result of strong  economic  conditions  throughout  the
United States,  which helped curtail states and municipalities'  need to borrow.
In this environment,  the Fund continued to adhere to its longstanding  strategy
of holding a diversified  portfolio of municipal  bonds selected after extensive
research into their issuers'  credit  quality.  The Fund's  portfolio  holdings,
allocations and strategies are subject to change.

    - COMPARING  THE FUND'S  PERFORMANCE  TO THE MARKET.  The graphs that follow
show the  performance  of a  hypothetical  $10,000  investment  in each class of
shares of the Fund held from the  inception of the class until July 31, 1999. In
the case of Class A shares,  performance is measured over a ten-year period.  In
the case of Class B shares,  performance  is measured  from the inception of the
class on March 16, 1993,  and in the case of Class C shares,  from the inception
of the class on August 29, 1995. The Fund's  performance  reflects the deduction
of the maximum initial sales charge on

                       10 Oppenheimer Municipal Bond Fund
<PAGE>

Class A shares and the applicable  contingent  deferred sales charge for Class B
and Class C shares.  The graphs  assume that all  dividends  and  capital  gains
distributions were reinvested in additional shares.

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

1. When-issued security to be delivered and settled after July 31, 1999.

2.  Represents  the current  interest  rate for a variable rate bond known as an
"inverse  floater"  which pays  interest  at a rate that varies  inversely  with
short-term interest rates. As interest rates rise, inverse floaters produce less
current income.  Their price may be more volatile than the price of a comparable
fixed-rate  security.  Inverse  floaters  amount to $73,050,655 or 10.79% of the
Fund's net assets as of July 31, 1999.

3.  Represents   securities  sold  under  Rule  144A,   which  are  exempt  from
registration under the Securities Act of 1933, as amended. These securities have
been  determined  to be  liquid  under  guidelines  established  by the Board of
Trustees.  These  securities  amount to  $27,924,502  or 4.12% of the Fund's net
assets as of July 31, 1999.

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

5.  Securities  with  an  aggregate  market  value  of  $2,623,996  are  held in
collateralized  accounts to cover initial  margin  requirements  on open futures
sales contracts. See Note 5 of Notes to Financial Statements.

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

As of July 31, 1999, securities subject to the alternative minimum tax amount to
$190,490,293 or 28.12% of the Fund's net assets.

NOTES TO FINANCIAL STATEMENTS

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

Oppenheimer  Municipal  Bond Fund (the Fund) is registered  under the Investment
Company  Act  of  1940,  as  amended,  as  a  diversified,  open-end  management
investment company.  The Fund's investment  objective is to seek as high a level
of current interest income exempt from federal income taxes as is available from
investing in municipal  securities,  while attempting to preserve  capital.  The
Fund's  investment  advisor is  OppenheimerFunds,  Inc. (the Manager).  The Fund
offers  Class A,  Class B and  Class C  shares.  Class A shares  are sold with a
front-end  sales charge,  on investments  up to $1 million.  Class B and Class C
shares may be subject to a contingent  deferred sales charge (CDSC). All classes
of shares  have  identical  rights to  earnings,  assets and voting  privileges,
except that each class has its own expenses directly  attributable to that class
and  exclusive  voting  rights  with  respect to matters  affecting  that class.
Classes A, B and C have separate  distribution  and/or  service  plans.  Class B
shares will automatically  convert to Class A shares six years after the date of
purchase.  The  following  is  a  summary  of  significant  accounting  policies
consistently followed by the Fund.

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

                       30 Oppenheimer Municipal Bond Fund
<PAGE>

================================================================================
SECURITIES PURCHASED ON A WHEN-ISSUED BASIS. Delivery and payment for securities
that have been  purchased  by the Fund on a forward  commitment  or  when-issued
basis can take place a month or more after the  transaction  date.  Normally the
settlement  date occurs within six months after the transaction  date;  however,
the fund may,  from time to time,  purchase  securities  whose  settlement  date
extends  beyond six months and  possibly as long as two years or more beyond the
trade date.  During this  period,  such  securities  do not earn  interest,  are
subject to market  fluctuation  and may  increase  or decrease in value prior to
their delivery.  The Fund maintains  segregated assets with a market value equal
to or greater  than the amount of its  purchase  commitments.  The  purchase  of
securities  on a  when-issued  or  forward  commitment  basis may  increase  the
volatility  of the  Fund's  net asset  value to the  extent  the Fund makes such
purchases while remaining substantially fully invested. As of July 31, 1999, the
Fund  had  entered  into  outstanding  when-issued  or  forward  commitments  of
$7,550,320.

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

--------------------------------------------------------------------------------
FEDERAL  TAXES.  The Fund intends to continue to comply with  provisions  of the
Internal  Revenue Code  applicable  to  regulated  investment  companies  and to
distribute  all of its  taxable  income,  including  any  net  realized  gain on
investments  not  offset by loss  carryovers,  to  shareholders.  Therefore,  no
federal income or excise tax provision is required.

--------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Fund has adopted a nonfunded retirement plan for the
Fund's  independent  Trustees.  Benefits  are based on years of service and fees
paid to each trustee during the years of service. During the year ended July 31,
1999,  a  provision  of  $4,456  was  made  for  the  Fund's  projected  benefit
obligations and payments of $18,457 were made to retired trustees,  resulting in
an accumulated liability of $235,370 as of July 31, 1999.

                    The Board of Trustees  has  adopted a deferred  compensation
plan for independent Trustees that enables Trustees to elect to defer receipt of
all or a portion of annual  compensation  they are  entitled to receive from the
Fund.  Under the plan, the  compensation  deferred is  periodically  adjusted as
though an equivalent  amount had been invested for the Trustees in shares of one
or more  Oppenheimer  funds  selected  by the  Trustee.  The amount  paid to the
Trustee  under the plan will be  determined  based upon the  performance  of the
selected  funds.  Deferral of Trustees'  fees under the plan will not affect the
net  assets of the Fund,  and will not  materially  affect  the  Fund's  assets,
liabilities or net income per share.

NOTES TO FINANCIAL STATEMENTS (Continued)

================================================================================
1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date.

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

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

--------------------------------------------------------------------------------
OTHER.  Investment transactions are accounted for as of the trade date. Original
issue  discount is accreted and premium is amortized in accordance  with federal
income tax  requirements.  For municipal bonds acquired after April 30, 1993, on
disposition or maturity,  taxable ordinary income is recognized to the extent of
the lesser of gain or market  discount  that would have accrued over the holding
period. Realized gains and losses on investments and unrealized appreciation and
depreciation are determined on an identified cost basis, which is the same basis
used for federal income tax purposes.

                    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.

</TABLE>

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

--------------------------------------------------------------------------------
CLASS A SERVICE  PLAN  FEES.  Under the Class A service  plan,  the  Distributor
currently  uses the fees it receives  from the Fund to pay brokers,  dealers and
other financial institutions. The Class A service plan permits reimbursements to
the Distributor at a rate of up to 0.25% of average annual net assets of Class A
shares. The Distributor makes payments to plan recipients quarterly at an annual
rate not to exceed 0.25% of the average annual net assets  consisting of Class A
shares of the Fund. For the fiscal year ended July 31, 1999,  payments under the
Class A Plan totaled  $1,290,905,  all of which was paid by the  Distributor  to
recipients.  That included  $109,431  paid to an affiliate of the  Distributor's
parent company. Any unreimbursed expenses the Distributor incurs with respect to
Class A shares in any fiscal year cannot be recovered in subsequent years.

--------------------------------------------------------------------------------
CLASS B AND CLASS C DISTRIBUTION AND SERVICE PLAN FEES. Under each plan, service
fees and distribution fees are computed on the average of the net asset value of
shares in the  respective  class,  determined  as of the  close of each  regular
business  day during the period.  The Class B and Class C plans  provide for the
Distributor  to  be  compensated  at a  flat  rate,  whether  the  Distributor's
distribution  expenses  are more or less than the amounts paid by the Fund under
the plan during the period for which the fee is paid.

                       34 Oppenheimer Municipal Bond Fund
<PAGE>

================================================================================
The  Distributor  retains the  asset-based  sales charge on Class B shares.  The
Distributor  retains the  asset-based  sales charge on Class C shares during the
first year the shares are outstanding.  The asset-based sales charges on Class B
and Class C shares  allow  investors  to buy shares  without a  front-end  sales
charge while  allowing the  Distributor  to  compensate  dealers that sell those
shares.

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

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

5. FUTURES CONTRACTS

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

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

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

                    Securities held in collateralized  accounts to cover initial
margin  requirements  on open futures  contracts  are noted in the  Statement of
Investments.  The  Statement  of Assets and  Liabilities  reflects a  receivable
and/or payable for the daily mark to market for variation margin.

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.

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

</TABLE>

================================================================================
6. ILLIQUID OR RESTRICTED SECURITIES

As of July 31, 1999, investments in securities included issues that are illiquid
or restricted.  Restricted  securities are often purchased in private  placement
transactions,  are not  registered  under the  Securities  Act of 1933, may have
contractual restrictions on resale, and are valued under methods approved by the
Board of Trustees as  reflecting  fair value.  A security may also be considered
illiquid  if it lacks a readily  available  market or if its  valuation  has not
changed for a certain  period of time.  The Fund  intends to invest no more than
10% of its  net  assets  (determined  at  the  time  of  purchase  and  reviewed
periodically)  in  illiquid  or  restricted   securities.   Certain   restricted
securities,  eligible for resale to qualified institutional  investors,  are not
subject to that  limitation.  The  aggregate  value of  illiquid  or  restricted
securities  subject to this  limitation  as of July 31, 1999,  was  $12,613,636,
which represents 1.86% of the Fund's net assets.

================================================================================
7. BANK BORROWINGS

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

                    The Fund had no borrowings outstanding during the year ended
July 31, 1999.

INDEPENDENT AUDITORS' REPORT

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

We have audited the accompanying statement of assets and liabilities,  including
the statement of investments,  of Oppenheimer Municipal Bond Fund as of July 31,
1999,  and the related  statement  of  operations  for the year then ended,  the
statements of changes in net assets for each of the years in the two-year period
then ended and the financial  highlights for each of the years in the three-year
period then ended,  the seven-month  period ended July 31, 1996, and each of the
years in the two-year period ended December 31, 1995. These financial statements
and financial  highlights are the responsibility of the Fund's  management.  Our
responsibility  is to  express  an opinion  on these  financial  statements  and
financial highlights based on our audits.

                    We  conducted  our  audits  in  accordance   with  generally
accepted  auditing  standards.  Those standards require that we plan and perform
the audit to obtain reasonable  assurance about whether the financial statements
and financial  highlights are free of material  misstatement.  An audit includes
examining,  on a test basis,  evidence supporting the amounts and disclosures in
the financial  statements.  Our procedures  included  confirmation of securities
owned as of July 31, 1999, by correspondence with the custodian and brokers; and
where  confirmations were not received from brokers, we performed other auditing
procedures.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

                    In our  opinion,  the  financial  statements  and  financial
highlights  referred to above  present  fairly,  in all material  respects,  the
financial  position of Oppenheimer  Municipal Bond Fund as of July 31, 1999, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the  two-year  period  then  ended,  and the  financial
highlights  for each of the  years in the  three-year  period  then  ended,  the
seven-month  period ended July 31,  1996,  and each of the years in the two-year
period ended December 31, 1995, in conformity with generally accepted accounting
principles.

FEDERAL INCOME TAX INFORMATION (Unaudited)

================================================================================
In early 2000, shareholders will receive information regarding all dividends and
distributions paid to them by the Fund during calendar year 1999. Regulations of
the U.S. Treasury  Department require the Fund to report this information to the
Internal Revenue Service.

                    None of the  dividends  paid by the Fund  during  the fiscal
year ended July 31,  1999,  are  eligible  for the  corporate  dividend-received
deduction.  The dividends were derived from interest on municipal  bonds and are
not subject to federal income tax. To the extent a shareholder is subject to any
state or local tax laws, some or all of the dividends received may be taxable.

                    The   foregoing   information   is   presented   to   assist
shareholders in reporting  distributions  received from the Fund to the Internal
Revenue Service.  Because of the complexity of the federal regulations which may
affect your individual tax return and the many variations in state and local tax
regulations,  we  recommend  that you  consult  your tax  advisor  for  specific
guidance.

Although  the Federal  Reserve  Board's  interest  rate hikes hurt the prices of
fixed income securities,  we believe these  inflation-fighting  actions will set
the stage for improved long-term Fund performance.

Despite a difficult investment  environment,  which resulted in a negative total
return for the Fund, we believe we have provided a consistent  rate of federally
tax-exempt income during the period.

We restructured  the Fund's portfolio by reducing average duration and employing
hedging  strategies in an effort to better  perform in an  environment of rising
interest rates.

PRESIDENT'S LETTER

Dear shareholder,

Insured Municipal Fund

Bridget A. Macaskill
President
Oppenheimer
Insured Municipal Fund

For many years,  we have  encouraged  investors  to consider  whether they could
tolerate more risk in their long-term  investments by participating in the stock
market, which has historically  provided higher long-term returns than any other
asset class. Today,  however,  we have a very different concern:  some investors
may be  assuming  too much risk by  concentrating  their  investments  in just a
handful of stocks or sectors or by "chasing performance.  " Alan Greenspan,  the
Chairman  of the  Federal  Reserve  Board,  has  stated his view that the recent
spectacular  returns of some  sectors of the market are partly  responsible  for
pushing our  economy to growth  rates that could lead to higher  inflation.  The
dramatic  rise in the  prices of a narrow  segment  of the  market  has  created
enormous wealth for some investors.  In turn,  those investors are spending at a
rate that the Fed believes may threaten the healthy growth of our economy.

That's why the Fed has been raising  interest rates steadily and decisively over
the past year. By making borrowing more expensive, the Fed is attempting to slow
economic growth. It is a precarious  balancing act: too much tightening  creates
the risk of recession, while too little opens the door to inflation.

The  implications  are clear:  investors  must be prepared for near-term  market
volatility. In the bond market, higher interest rates usually lead to lower bond
prices.  In the stock  market,  slower  economic  growth could reduce  corporate
earnings and put downward pressure on stock prices.  Highly valued stocks may be
particularly vulnerable to a correction.  The Securities and Exchange Commission
Chairman,  Arthur Levitt,  has cautioned  investors against the expectation that
the types of returns seen in the recent bull market will last forever. We agree.

PRESIDENT'S LETTER

Because of the  prospect of continued  market  volatility,  we encourage  you to
consider  diversifying your investments.  Indeed,  diversification  may help you
mitigate  the effects of sharp  declines  in any one area.  It may also help you
better position your portfolio to seek greater returns over the long run.

While "new  economy"  stocks have risen since our last report to you,  many "old
economy" stocks are selling at unusually low prices. In the bond market,  higher
interest rates over the short term may reduce inflation  concerns,  which should
be beneficial over the long term. By buying out-of-favor investments, you may be
able to profit when and if they return to favor in the future. Of course,  there
is no assurance that value investing will return to favor in the market,  but it
may be a diversification strategy to consider for part of your portfolio.

What specific investments should you consider today so that you are prepared for
tomorrow?  The answer depends on your individual investing goals, risk tolerance
and financial  circumstances.  We urge you to talk with your  financial  advisor
about ways to diversify  your  portfolio.  This may include  considering  global
diversification  as part of your strategy.  While  investing  abroad has special
risks,  such as the  effects of foreign  currency  fluctuation,  it also  offers
opportunities  to participate in global economic growth and to hedge against the
volatility in U. S. markets.

We thank you for your continued confidence in OppenheimerFunds, The Right Way to
Invest.

Sincerely,




 /s/ James C. Swain   /s/ Bridget A. Macaskill

AN INTERVIEW WITH YOUR FUND'S MANAGER



[PHOTO]

Portfolio Management Team (l to r)
Christian Smith (Portfolio Manager) Robert Patterson

How would you  characterize the Fund's  performance  during the six-month period
that ended March 31, 2000?

A.  The  recent  six-month  period  proved  challenging  for  most  fixed-income
securities.  Insured  municipal  bond funds  suffered with the rest of the fixed
income market.  While it is not surprising that  Oppenheimer  Insured  Municipal
Fund's  total  return  was  negative  in  this  difficult  environment,  we  are
nevertheless disappointed with these results.

At the same  time,  we are  pleased  that  the  Fund  met its goal of  providing
investors  with a consistent  rate of  federally  tax-exempt  income  during the
period. For investors in the top federal tax bracket,  the Fund's Class A shares
have a tax-free yield of 5.13%, which works out to a taxable equivalent yield of
8.02%.1  That level of taxable  return  would be  difficult  to achieve  without
taking substantial credit risk. Yet, during the period, the municipal bonds held
in our portfolio averaged AAA credit quality.

What made this such a challenging period for municipal bond investing?

Municipal  bonds,  like most fixed income  investments,  tend to be sensitive to
changing interest rates. The income yield of these securities remains fixed from
the time they are issued until they mature.  As a result,  when  interest  rates
rise over time, a bond's  constant  yield appears less  attractive to investors.
When  interest  rates fall the yield  appears more  attractive.  That's why bond
prices  generally  fall when interest  rates rise,  and rise when interest rates
fall.

1. Dividend yields are calculated based on net asset value (NAV), are annualized
and divided by the offering  price as of the Fund's  distribution  date on March
10, 2000.  Dividend  yields at NAV do not include sales  charges.  Falling share
prices will tend to artificially raise yields.

AN INTERVIEW WITH YOUR FUND'S MANAGER

"Municipal bonds offer attractive rates of tax-exempt income combined with less
credit risk and lower volatility than many other types of bonds. "

During the period,  the Federal Reserve Board (the Fed) raised interest rates in
an effort to slow the pace of the U. S.  economy  and reduce the  potential  for
rising  inflation.  Although actual inflation  remained at low levels,  consumer
spending was  exceedingly  strong,  prompting the Fed to signal that  additional
rate hikes might be necessary. The Fed's actions weakened bond prices, including
prices of municipal bonds.

How did you manage the Fund under these conditions?

We actively  managed  the Fund's  average  duration in light of rising  interest
rates.  Duration  refers to the length of time before a bond  matures,  and is a
measure  of a bond's  sensitivity  to changes in  interest  rates.  The longer a
bond's duration, the greater the impact of rising or falling interest rates. For
that reason,  bond funds tend to benefit from holding a portfolio of  securities
with a longer  average  duration  during times of falling  interest  rates,  and
shorter average duration during times of rising rates.

When I assumed leadership of the portfolio management team in November 1999, the
Fund was positioned to take advantage of a decline in interest  rates.  However,
as evidence mounted that rates were rising and would probably  continue to rise,
we changed that strategy in order to emphasize shorter term instruments.

Unfavorable  market  conditions  prevented  us  from  implementing  our  shorter
duration  strategy  until the  beginning  of Year 2000.  When market  conditions
improved  in  January,  we began  selling  some of our  longer  duration  bonds,
replacing  them with shorter  duration  instruments.  We also employed a hedging
strategy of shorting municipal bond futures to further reduce the Fund's average
duration.  By March 31, 2000,  the end of the period,  we had lowered the Fund's
average  duration from  approximately 10 years to less than eight years, in line
with most insured municipal bond funds.

Because of ongoing market  volatility,  the Fund's returns may fluctuate and may
be less than the results shown.

What is your outlook for the coming months?

Although  rising  interest  rates hurt the Fund during the last six  months,  we
believe  the  Fed's  aggressive,  inflation-fighting  stance  is likely to prove
beneficial to the Fund's  investors over the long term. By raising rates to slow
the  economy,   the  Fed  is  reducing  the  possibility  of  future  inflation.
Uncontrolled  inflation  could have an even greater  adverse  affect on the Fund
than recent rate  increases.  On the other hand,  if the Fed's  actions  lead to
slowing economic  growth,  the result may eventually be an environment of stable
or falling interest rates that would benefit the Fund's investors.

Still,  we believe  interest  rates are likely to  continue  to rise in the near
future while the Fed pursues its anti-inflationary course. Accordingly,  for the
time being we plan to persevere  in our efforts to better  position the Fund for
an environment of rising interest rates. We also believe that insured  municipal
bonds will continue to provide  attractive  rates of tax-exempt  current  income
with less credit risk and lower  levels of  volatility  than many other types of
bonds  offering  similar  or even lower  yields.  Carefully  searching  for high
quality investments that help investors to maximize their current income is what
makes  Oppenheimer  Insured Municipal Fund an important part of The Right Way to
Invest.

NOTES

In reviewing performance and rankings, please remember that past performance
does not guarantee future results. Investment return and principal value of an
investment in the Fund will fluctuate so that an investor's shares, when
redeemed, maybe worth more or less than the original cost. For quarterly updates
on the Fund's performance, please contact your financial advisor, call us at
1. 800. 525. 7048 or visit our website at www. oppenheimerfunds. com.

Total returns include  changes in share price and  reinvestment of dividends and
capital gains distributions in a hypothetical  investment for the periods shown.
Cumulative total returns are not annualized. The Fund's total returns and yields
shown do not show the  effects of income  taxes on an  individual's  investment.
Taxes may reduce your actual  investment  returns on income or gains paid by the
Fund or any gains you may realize if you sell your shares.

Class A shares were first publicly offered on 11/11/86.  Unless otherwise noted,
Class A returns  include the current maximum initial sales charge of 4. 75%. The
Fund's  maximum  sales  charge for Class A shares was lower prior to 2/1/93,  so
actual performance may have been higher.

Class B shares  of the Fund  were  first  publicly  offered  on  5/3/93.  Unless
otherwise  noted,  Class B returns  include the applicable  contingent  deferred
sales charge of 5% (1-year) and 2% (5-year).  Because class B shares  convert to
class A shares 72 months after purchase,  the "life of class" return for Class B
uses Class A  performance  for the period after  conversion.  Class B shares are
subject to an annual 0. 75% asset-based sales charge.

Class C shares  of the Fund were  first  publicly  offered  on  8/29/95.  Unless
otherwise noted, Class C returns include the contingent deferred sales charge of
1% for the  1-year  period.  Class C shares  are  subject  to an  annual  0. 75%
asset-based sales charge.

An explanation of the  calculation of performance is in the Fund's  Statement of
Additional Information.

1.  Securities  with  an  aggregate  market  value  of  $1,096,066  are  held in
collateralized  accounts to cover initial  margin  requirements  on open futures
sales contracts. See Note 5 of Notes to Financial Statements.  2. Represents the
current  interest  rate for a variable  rate bond known as an "inverse  floater"
which pays interest at a rate that varies  inversely  with  short-term  interest
rates.  As interest rates rise,  inverse  floaters  produce less current income.
Their  price  maybe  more  volatile  than the price of a  comparable  fixed-rate
security.  Inverse  floaters  amount to  $11,380,151  or 9.62% of the Fund's net
assets as of March 31, 2000. 3. When-issued security to be delivered and settled
after March 31, 2000. 4. Represents the current  interest rate for a variable or
increasing rate security.  5. For zero coupon bonds,  the interest rate shown is
the effective yield on the date of purchase. 6. Represents securities sold under
Rule 144A, which are exempt from registration  under the Securities Act of 1933,
as amended.  These securities have been determined to be liquid under guidelines
established by the Board of Trustees.  These securities  amount to $1,675,785 or
1.42% of the Fund's net assets as of March 31, 2000.

As of March 31, 2000,  securities subject to the alternative  minimum tax amount
to $19,146,954 or 16.19% of the Fund's net assets.

NOTES TO FINANCIAL STATEMENTS Unaudited
--------------------------------------------------------------------------------

1. Significant Accounting Policies

Oppenheimer   Insured  Municipal  Fund  (the  Fund)  is  a  separate  series  of
Oppenheimer Municipal Fund, an open-end management investment company registered
under the  Investment  Company Act of 1940,  as amended.  The Fund's  investment
objective is to seek a high level of current  income exempt from federal  income
tax. The Fund's investment advisor is OppenheimerFunds, Inc. (the Manager).

The Fund offers Class A, Class B and Class C shares.  Class A shares are sold at
their offering price, which is normally net asset value plus an initial sales
charge. Class B and Class C shares are sold without an initial sales charge but
may be subject to a contingent deferred sales charge (CDSC). All classes of
shares have identical rights to earnings, assets and voting privileges, except
that each class has its own expenses directly attributable to that class and
exclusive voting rights with respect to matters affecting that class. Classes A,
B and C shares have separate distribution and/or service plans. Class B shares
will automatically convert to Class A shares six years after the date of
purchase. The following is a summary of significant accounting policies
consistently followed by the Fund.
--------------------------------------------------------------------------------

Securities Valuation. Securities for which quotations are readily available are
valued at the last sale price, or if in the absence of a sale, at the last sale
price on the prior trading day if it is within the spread of the closing bid and
asked prices, and if not, at the closing bid price. Securities (including
restricted securities) for which quotations are not readily available are valued
primarily using dealer-supplied valuations, a portfolio pricing service
authorized by the Board of Trustees, or at their fair value. Fair value is
determined in good faith under consistently applied procedures under the
supervision of the Board of Trustees. Short-term "money market type" debt
securities with remaining maturities of sixty days or less are valued at cost
(or last determined  market value) and adjusted for amortization or accretion to
maturity of any premium or discount.
--------------------------------------------------------------------------------

Securities Purchased on a When-Issued Basis. Delivery and payment for securities
that have been  purchased  by the Fund on a forward  commitment  or  when-issued
basis can take place a month or more after the  transaction  date.  Normally the
settlement  date occurs within six months after the transaction  date;  however,
the Fund may,  from time to time,  purchase  securities  whose  settlement  date
extends beyond six months and possibly as long as two years or more beyond trade
date. During this period,  such securities do not earn interest,  are subject to
market  fluctuation  and may  increase  or  decrease  in  value  prior  to their
delivery.  The Fund maintains  segregated assets with a market value equal to or
greater than the amount of its purchase commitments.  The purchase of securities
on a when-issued or forward  commitment basis may increase the volatility of the
Fund's  net asset  value to the  extent  the Fund  makes  such  purchases  while
remaining  substantially  fully  invested.  As of March 31,  2000,  the Fund had
entered into net outstanding when-issued or forward commitments of $1,086,775.

NOTES TO FINANCIAL STATEMENTS Unaudited / Continued
--------------------------------------------------------------------------------

1. Significant Accounting Policies Continued
In  connection  with its  ability to purchase  securities  on a  when-issued  or
forward commitment basis, the Fund may enter into mortgage dollar-rolls in which
the Fund sells  securities for delivery in the current month and  simultaneously
contracts with the same  counterparty to repurchase  similar (same type,  coupon
and maturity) but not identical  securities on a specified future date. The Fund
records each dollar-roll as a sale and a new purchase transaction.
--------------------------------------------------------------------------------

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

Federal  Taxes.  The Fund intends to continue to comply with  provisions  of the
Internal  Revenue Code  applicable  to  regulated  investment  companies  and to
distribute  all of its  taxable  income,  including  any  net  realized  gain on
investments  not offset by loss  carry-overs,  to  shareholders.  Therefore,  no
federal income or excise tax provision is required
--------------------------------------------------------------------------------

Dividends and  Distributions  to  Shareholders.  Dividends and  distributions to
shareholders,  which are determined in accordance  with income tax  regulations,
are recorded on the ex-dividend date.
--------------------------------------------------------------------------------

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

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

Other.  Investment  transactions  are accounted  for as of trade date.  Original
issue  discount is accreted and premium is amortized in accordance  with federal
income tax  requirements.  For municipal bonds acquired after April 30, 1993, on
disposition or maturity,  taxable ordinary income is recognized to the extent of
the lesser of gain or market  discount  that would have accrued over the holding
period. Realized gains and losses on investments and unrealized appreciation and
depreciation are determined on an identified cost basis, which is the same basis
used for federal income tax purposes.

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.

</TABLE>

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

Class A Service  Plan  Fees.  Under the Class A service  plan,  the  Distributor
currently  uses the fees it receives  from the Fund to pay brokers,  dealers and
other financial institutions. The Class A service plan permits reimbursements to
the Distributor at a rate of up to 0.25% of average annual net assets of Class A
shares purchased. The Distributor makes payments to plan recipients quarterly at
an annual rate not to exceed 0.25% of the average  annual net assets  consisting
of Class A shares of the Fund. For the six months ended March 31, 2000, payments
under  the  Class  A  plan  totaled  $112,671,  all of  which  was  paid  by the
Distributor  to  recipients.  That  included  $5,321 paid to an affiliate of the
Manager. Any unreimbursed  expenses the Distributor incurs with respect to Class
A shares in any fiscal year cannot be recovered in subsequent years.

24   OPPENHEIMER INSURED MUNICIPAL FUND
<PAGE>

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

Class B and Class C Distribution and Service Plan Fees. Under each plan, service
fees and distribution fees are computed on the average of the net asset value of
shares in the  respective  class,  determined  as of the  close of each  regular
business  day during the period.  The Class B and Class C plans  provide for the
Distributor  to  be  compensated  at a  flat  rate,  whether  the  Distributor's
distribution  expenses  are more or less than the amounts paid by the Fund under
the plan during the period for which the fee is paid.

The  Distributor  retains the  asset-based  sales charge on Class B shares.  The
Distributor  retains the  asset-based  sales charge on Class C shares during the
first year the shares are outstanding.  The asset-based sales charges on Class B
and Class C shares  allow  investors  to buy shares  without a  front-end  sales
charge while  allowing the  Distributor  to  compensate  dealers that sell those
shares.

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

Distribution  fees paid to the  Distributor  for the six months  ended March 31,
2000, were as follows:

5. Futures Contracts

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

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

25   OPPENHEIMER INSURED MUNICIPAL FUND
<PAGE>


NOTES TO FINANCIAL STATEMENTS Unaudited / Continued
--------------------------------------------------------------------------------

5. Futures Contracts Continued

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

Securities held in collateralized  accounts to cover initial margin requirements
on open  futures  contracts  are  noted in the  Statement  of  Investments.  The
Statement of Assets and Liabilities reflects a receivable and/or payable for the
daily mark to market for variation margin.

Risks of entering  into  futures  contracts  (and related  options)  include the
possibility  that there may be an illiquid market and that a change in the value
of the  contract or option may not  correlate  with  changes in the value of the
underlying securities.

As of March 31, 2000, the Fund had outstanding futures contracts as follows:

6. Bank Borrowings

The Fund may borrow from a bank for temporary or emergency  purposes  including,
with-out limitation,  funding of shareholder redemptions provided asset coverage
for  borrowings  exceeds  300%.  The Fund has entered  into an  agreement  which
enables it to participate with other  Oppenheimer  funds in an unsecured line of

PRESIDENT'S LETTER

Bridget A. Macaskill
President
Oppenheimer
Municipal Bond Fund

DEAR SHAREHOLDER,

Whenever a new year begins--let alone a new decade or century--it makes sense to
pause a moment to assess where we've been and where we're going.

     In  retrospect,  U.S.  stocks and bonds in 1999 were  subject to sudden and
substantial swings in investor sentiment because of economic  uncertainty.  When
the year began,  investors were concerned that growth in the United States might
slow in response to economic  weakness  overseas.  At mid-year,  investors  were
concerned that the economy was too strong,  potentially rekindling  inflationary
pressures.  Yet, by year end, it became clearer that while the U.S. economy grew
robustly in 1999, inflation remained at low levels.  Indeed,  investors appeared
more comfortable  with the economy after the Federal Reserve Board  demonstrated
its  inflation-fighting  resolve by raising  interest  rates three times between
June and November.

     As is normal in a rising-interest-rate  environment,  bond prices generally
declined in 1999, led lower by U.S.  Treasury bonds. In the stock market,  while
most major indices advanced,  strong performance was mostly limited to a handful
of large-capitalization  growth companies,  principally in the technology arena.
Smaller and value-oriented stocks provided particularly  lackluster returns and,
overall, foreign stocks outperformed U.S. stocks in 1999.

     Looking forward, we expect the U.S. economy to remain on a moderate-growth,
low-inflation   course.  As  recent  revisions  of  1999's  economic  statistics
demonstrated,  the economy has defied many  analysts'  forecasts by growing at a
strong rate, which should be positive for the bond market.  Similarly,  positive
economic  forces could help the stock  market's  performance  broaden to include
value-oriented and smaller stocks.

     We see particularly compelling opportunities outside of the U.S. market.
Many foreign stocks also ended 1999 more attractively valued than large-cap U.S.
stocks, and economic trends in overseas markets could lead to higher stock
prices. In Europe, corporate restructuring has just begun, giving

PRESIDENT'S LETTER
--------------------------------------------------------------------------------

companies   there  the  same  potential  for   cost-cutting   and   productivity
improvements  that  U.S.  companies  enjoyed  10 years  ago.  In Japan and Asia,
economic  recovery  is expected to gain  strength,  which could allow  stocks to
rally from relatively low levels.

     Another  1999  trend that  should  remain in force in 2000 is the growth of
businesses  related to the Internet.  The rise of  e-commerce  has been good for
consumers and the economy because of greater price competition, which has helped
keep inflation under control. The Internet has also been good for investors,  as
even  companies  with no earnings  have seen their stock prices  soar.  Clearly,
while the Internet is here to stay,  not all "dot-com"  companies  will survive,
and many of these high-flying Internet stocks will eventually--and  perhaps very
suddenly--return  to more  reasonable  levels.  The  long-term  winners are most
likely to be  companies  that  support the  Internet's  growth  with  content or
infrastructure.

     What  else is in  store  for  investors  in  2000?  While we do not have an
infallible  crystal ball, we believe that in almost any investment  environment,
consistent  success stems from an  unwavering  focus on  fundamental  investment
principles such as maintaining a long-term perspective, using diversification to
manage risks, and availing oneself of the services of a knowledgeable  financial
advisor.  Indeed,  these principles serve as the foundation for every investment
we offer,  helping to make  OppenheimerFunds THE RIGHT WAY TO INVEST in 2000 and
beyond.


Sincerely,

/s/ Bridget A. Macaskill

AN INTERVIEW WITH YOUR FUND'S MANAGER
--------------------------------------------------------------------------------

[PHOTO]
Portfolio Management Team (l to r)
Christian Smith
Robert Patterson
(Portfolio Manager)

HOW DID OPPENHEIMER  MUNICIPAL BOND FUND PERFORM OVER THE SIX-MONTH  PERIOD THAT
ENDED JANUARY 31, 2000?

A. The Fund's  performance over the past six months reflected a very challenging
investment  environment.  During the  reporting  period,  stronger-than-expected
economic growth in both domestic and overseas markets fueled investors' concerns
that  inflationary  pressures might reemerge in the U.S.  economy.  As a result,
interest rates and most bond yields rose. Because bond yields and prices move in
opposite directions, higher interest rates eroded the value of many fixed income
securities,  including municipal bonds. In addition,  the tax-exempt bond market
was  subject to  adverse  supply-and-demand  influences,  which  eroded  returns
further.

WHAT ECONOMIC FORCES AFFECTED MUNICIPAL BONDS AND THE FUND?

When the reporting  period began on July 1, 1999, the Federal  Reserve Board had
just  implemented  its first interest rate hike of 1999. They did so in response
to concerns  that  unsustainable  economic  growth might  reignite  inflationary
pressures. While inflation had not yet accelerated, early warning signs included
very low  unemployment,  high levels of consumer  spending  and  borrowing,  and
rising commodities  prices. When the economy  subsequently gained momentum,  the
Federal  Reserve raised  short-term  interest rates again in August and November
for a total  increase of 0.75  percentage  points during the  reporting  period.
These increases were quickly reflected in municipal bond prices.

<PAGE>

AN INTERVIEW WITH YOUR FUND'S MANAGER
--------------------------------------------------------------------------------

WHAT SUPPLY-AND-DEMAND FACTORS INFLUENCED THE FUND'S PERFORMANCE?

Higher  interest  rates reduced  demand for municipal  bonds from  corporate and
institutional  investors.  In addition,  many mutual fund  shareholders  shifted
assets  from bond funds to stock  funds  because of the stock  market's  stellar
returns,  which reduced overall demand from tax-exempt  mutual funds. With these
investors effectively absent from the market, municipal bond yields rose further
than would have been expected from the Fed's interest rate increases alone.

HOW WAS THE FUND MANAGED IN THIS ENVIRONMENT?

We primarily  focused on repositioning the portfolio to a more defensive posture
in order to provide a cushion against the adverse effects of a declining market.
With higher yielding  securities  available,  we sold some of our lower yielding
holdings to enhance  the Fund's  income  stream.  Although we sold many of these
securities at a lower price than their  original cost, we were able to use these
losses to offset earlier gains,  helping to reduce capital gains tax liabilities
for our shareholders.

WHERE DID YOU FIND THE MOST ATTRACTIVE INVESTMENT OPPORTUNITIES?

We found particularly  attractive yields in insured bonds with maturities in the
20-year  range.  Because the yield  difference  between  high  quality and lower
quality  bonds  had  narrowed,  we  believed  that we  would  not be  adequately
compensated  for the extra risks that lower yielding bonds entail.  We preferred
the  20-year   maturity   range   because  their  prices  held  up  better  than
intermediate-term   securities  in  the  10-  to  15-year   range,   which  were
particularly hard hit by the lack of demand from institutional buyers.

BENEFIT FROM BETTER MARKET CONDITIONS IN 2000."
[/SIDENOTE:]

                     4    OPPENHEIMER MUNICIPAL BOND FUND

<PAGE>

On the other hand,  we  carefully  avoided  those  sectors of the market that we
regarded  as  troublesome,  including  healthcare  and  utilities.  However,  we
maintained our holdings of "special  situations," which are bonds that we regard
as  undervalued  at the time of purchase,  and that we believe will benefit from
the  improving  credit  quality  of their  issuers.  One  example  of a  special
situation bond is a college in Savannah,  Georgia,  that issued tax-exempt bonds
at an  inopportune  time,  requiring  them  to  offer  extra  yield  to  attract
investors'  attention.  When  institutional  demand  returns to the markets,  we
believe that these bonds' value will rise. However,  during the past six months,
they have hurt the Fund's returns.

WHAT IS YOUR OUTLOOK FOR THE NEW YEAR?

We are  cautious  over the near term and  optimistic  over the longer  term.  We
expect the U.S. economy to remain strong over the next several months, which may
prompt  the  Federal   Reserve  Board  to  increase   interest   rates  further.
Accordingly,  we intend to maintain our  defensive  posture until we believe the
Fed's moves toward a more restrictive monetary policy are complete.  If and when
evidence  emerges that the bulk of interest rate increases are behind us, we are
likely to see better performance from our "special situations"  holdings. We are
also  likely to see the return of  corporate  and  institutional  buyers,  which
should help support tax-exempt bond prices.

opportunities more  aggressively,  with an eye toward locking in high yields for

appreciation. In our view, this kind of active management approach is what makes

(1)  Securities  with an  aggregate  market  value  of  $5,060,350  are  held in
collateralized  accounts to cover initial  margin  requirements  on open futures
sales contracts. See Note 5 of Notes to Financial Statements. (2) Represents the
current interest rate for a variable rate bond known as an inverse floater which
pays interest at a rate that varies inversely with short-term interest rates. As
interest rates rise,  inverse floaters produce less current income.  Their price
may be more volatile than the price of a comparable fixed-rate security. Inverse
floaters  amount to  $57,142,575 or 9.76% of the Fund's net assets as of January
31, 2000. (3) Represents  securities sold under Rule 144A, which are exempt from
registration under the Securities Act of 1933, as amended. These securities have
been  determined  to be  liquid  under  guidelines  established  by the Board of
Trustees.  These  securities  amount to  $26,158,774  or 4.47% of the Fund's net
assets as of January 31, 2000.  (4) For zero coupon  bonds,  the  interest  rate
shown is the  effective  yield on the date of purchase.  (5)  Identifies  issues
considered  to be  illiquid  or  restricted--See  Note 6 of Notes  to  Financial
Statements.  (6)  Represents  the  current  interest  rate  for  a  variable  or
increasing rate security.

AS OF JANUARY 31, 2000, SECURITIES SUBJECT TO THE ALTERNATIVE MINIMUM TAX AMOUNT
TO $152,237,304 OR 26% OF THE FUND'S NET ASSETS.

NOTES TO FINANCIAL STATEMENTS  Unaudited

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer  Municipal  Bond Fund (the Fund) is registered  under the Investment
Company  Act  of  1940,  as  amended,  as  a  diversified,  open-end  management
investment company.  The Fund's investment  objective is to seek as high a level
of current interest income exempt from federal income taxes as is available from
investing in municipal  securities,  while attempting to preserve  capital.  The
Fund's investment advisor is OppenheimerFunds, Inc. (the Manager).

     The Fund  offers  Class A,  Class B and Class C shares.  Class A shares are
sold at their offering price,  which is normally net asset value plus an initial
sales  charge.  Class B and Class C shares are sold  without  an  initial  sales
charge but may be subject to a  contingent  deferred  sales charge  (CDSC).  All
classes  of  shares  have  identical  rights  to  earnings,  assets  and  voting
privileges, except that each class has its own expenses directly attributable to
that class and exclusive  voting rights with respect to matters  affecting  that
class.  Classes A, B and C shares  have  separate  distribution  and/or  service
plans.  Class B shares  will  automatically  convert to Class A shares six years
after the date of purchase. The following is a summary of significant accounting
policies consistently followed by the Fund.

--------------------------------------------------------------------------------
SECURITIES VALUATION.  Securities for which quotations are readily available are
valued at the last sale price,  or if in the absence of a sale, at the last sale
price on the prior trading day if it is within the spread of the closing bid and
asked  prices,  and if not,  at the  closing  bid price.  Securities  (including
restricted securities) for which quotations are not readily available are valued
primarily  using  dealer-supplied   valuations,   a  portfolio  pricing  service
authorized  by the Board of  Trustees,  or at their  fair  value.  Fair value is
determined  in good  faith  under  consistently  applied  procedures  under  the
supervision  of the Board of  Trustees.  Short-term  "money  market  type"  debt
securities  with  remaining  maturities of sixty days or less are valued at cost
(or last determined  market value) and adjusted for amortization or accretion to
maturity of any premium or discount.

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

--------------------------------------------------------------------------------
FEDERAL  TAXES.  The Fund intends to continue to comply with  provisions  of the
Internal  Revenue Code  applicable  to  regulated  investment  companies  and to
distribute  all of its  taxable  income,  including  any  net  realized  gain on
investments  not  offset by loss  carryovers,  to  shareholders.  Therefore,  no
federal income or excise tax provision is required.

1. SIGNIFICANT ACCOUNTING POLICIES  Continued

TRUSTEES' COMPENSATION. The Fund has adopted an unfunded retirement plan for the
Fund's independent Board of Trustees. Benefits are based on years of service and
fees paid to each  trustee  during the years of  service.  During the six months
ended January 31, 2000, a provision of $2,871 was made for the Fund's  projected
benefit  obligations,  resulting in an  accumulated  liability of $238,241 as of
January 31, 2000.

     The  Board  of  Trustees  has  adopted  a  deferred  compensation  plan for
independent trustees that enables trustees to elect to defer receipt of all or a
portion of annual compensation they are entitled to receive from the Fund. Under
the plan,  the  compensation  deferred  is  periodically  adjusted  as though an
equivalent  amount had been  invested for the Board of Trustees in shares of one
or more Oppenheimer funds selected by the trustee.  The amount paid to the Board
of Trustees under the plan will be determined  based upon the performance of the
selected  funds.  Deferral of trustees'  fees under the plan will not affect the
net  assets of the Fund,  and will not  materially  affect  the  Fund's  assets,
liabilities or net investment income per share.

--------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date.

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

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

--------------------------------------------------------------------------------
OTHER.  Investment  transactions  are accounted  for as of trade date.  Original
issue  discount is accreted and premium is amortized in accordance  with federal
income tax  requirements.  For municipal bonds acquired after April 30, 1993, on
disposition or maturity,  taxable ordinary income is recognized to the extent of
the lesser of gain or market  discount  that would have accrued over the holding
period. Realized gains and losses on investments and unrealized appreciation and
depreciation are determined on an identified cost basis, which is the same basis
used for federal income tax purposes.

     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.

</TABLE>


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

--------------------------------------------------------------------------------
CLASS A SERVICE  PLAN  FEES.  Under the Class A service  plan,  the  Distributor
currently  uses the fees it receives  from the Fund to pay brokers,  dealers and
other financial institutions. The Class A service plan permits reimbursements to
the Distributor at a rate of up to 0.25% of average annual net assets of Class A
shares purchased. The Distributor makes payments to plan recipients quarterly at
an annual rate not to exceed 0.25% of the average  annual net assets  consisting
of Class A shares  of the Fund.  For the six  months  ended  January  31,  2000,
payments under the Class A plan totaled  $630,865,  all of which was paid by the
Distributor  to  recipients.  That included  $49,299 paid to an affiliate of the
Manager. Any unreimbursed  expenses the Distributor incurs with respect to Class
A shares in any fiscal year cannot be recovered in subsequent years.

--------------------------------------------------------------------------------
CLASS B AND CLASS C DISTRIBUTION AND SERVICE PLAN FEES. Under each plan, service
fees and distribution fees are computed on the average of the net asset value of
shares in the  respective  class,  determined  as of the  close of each  regular
business  day during the period.  The Class B and Class C plans  provide for the
Distributor  to  be  compensated  at a  flat  rate,  whether  the  Distributor's
distribution  expenses  are more or less than the amounts paid by the Fund under
the plan during the period for which the fee is paid.


                     26   OPPENHEIMER MUNICIPAL BOND FUND

<PAGE>


The  Distributor  retains the  asset-based  sales charge on Class B shares.  The
Distributor  retains the  asset-based  sales charge on Class C shares during the
first year the shares are outstanding.  The asset-based sales charges on Class B
and Class C shares  allow  investors  to buy shares  without a  front-end  sales
charge while  allowing the  Distributor  to  compensate  dealers that sell those
shares.

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

Distribution  fees paid to the  Distributor for the six months ended January 31,
2000, were as follows:

5. FUTURES CONTRACTS

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

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

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

     Securities  held  in  collateralized   accounts  to  cover  initial  margin
requirements   on  open  futures   contracts  are  noted  in  the  Statement  of
Investments.  The  Statement  of Assets and  Liabilities  reflects a  receivable
and/or payable for the daily mark to market for variation margin.

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.

As of January 31, 2000, the Fund had outstanding futures contracts as follows:

</TABLE>




--------------------------------------------------------------------------------
6. ILLIQUID OR RESTRICTED SECURITIES

As of January 31,  2000,  investments  in  securities  included  issues that are
illiquid or restricted.  Restricted  securities  are often  purchased in private
placement transactions, are not registered under the Securities Act of 1933, may
have contractual  restrictions on resale,  and are valued under methods approved
by the Board of  Trustees  as  reflecting  fair  value.  A security  may also be
considered  illiquid if it lacks a readily  available market or if its valuation
has not changed for a certain period of time. The Fund intends to invest no more
than 10% of its net assets  (determined  at the time of  purchase  and  reviewed
periodically)  in  illiquid  or  restricted   securities.   Certain   restricted
securities,  eligible for resale to qualified institutional  investors,  are not
subject to that  limitation.  The  aggregate  value of  illiquid  or  restricted
securities subject to this limitation as of January 31, 2000 was $75,000,  which
represents 0.01% of the Fund's net assets.

--------------------------------------------------------------------------------
 7. BANK BORROWINGS

The Fund may borrow from a bank for temporary or emergency  purposes  including,
without limitation,  funding of shareholder  redemptions provided asset coverage
for  borrowings  exceeds  300%.  The Fund has entered  into an  agreement  which
enables it to participate with other  Oppenheimer  funds in an unsecured line of
credit with a bank, which permits  borrowings up to $400 million,  collectively.
Interest is charged to each fund,  based on its  borrowings,  at a rate equal to
the  Federal  Funds Rate plus 0.45%.  Borrowings  are payable 30 days after such
loan is  executed.  The Fund  also pays a  commitment  fee equal to its pro rata
share of the average unutilized amount of the credit facility at a rate of 0.08%
per annum.

     The Fund had no borrowings  outstanding during the six months ended January
31, 2000.

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  $58,372,338  or  10.15%,
$11,380,151 or 9.62%  (Combined  $69,752,489 or 10.06%) of the Fund's net assets
as of March 31, 2000. 2. Represents  securities sold under Rule 144A,  which are
exempt from  registration  under the Securities  Act of 1933, as amended.  These
securities have been determined to be liquid under guidelines established by the
Board of Trustees.  These securities amount to $26,858,124 or 4.67%,  $1,675,785
or 1.42%  (Combined  $28,533,909  or 4.11%) of the Fund's net assets as of March
31, 2000.  3. For zero coupon  bonds,  the interest  rate shown is the effective
yield on the date of purchase.  4.  Represents  the current  interest rate for a
variable or increasing rate security.

Item 15.  Indemnification

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

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