Additional Information About the Fund's Investment Policies and Risks

The investment  objective,  the principal investment policies and the main risks
of the Fund are  described  in the  Prospectus.  This  Statement  of  Additional
Information contains supplemental information about those policies and risks and
the types of securities that the Fund's  investment  Manager,  OppenheimerFunds,
Inc., can select for the Fund. Additional information is also provided about the
strategies that the Fund can 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 can 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 in seeking its goal. It can
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,  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,  if interest  rates  decreased  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 investment  reasons,  such as 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.

|X| Portfolio  Turnover.  "Portfolio  turnover"  describes the rate at which the
Fund traded its portfolio  securities  during its last fiscal year. For example,
if a fund sold all of its  securities  during the year,  its portfolio  turnover
rate would have been 100%.  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.  Additionally,  the  realization  of capital  gains from
selling  portfolio  securities may result in distributions of taxable  long-term
capital gains to  shareholders,  since the Fund will normally  distribute all of
its capital  gains  realized each year, to avoid excise taxes under the Internal
Revenue Code.


<PAGE>


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

Municipal  Securities.  The types of municipal  securities in which the Fund can
invest are  described in the  Prospectus  under "About the Fund's  Investments."
Municipal  securities  generally include general obligation bonds, revenue bonds
and  notes,  and  municipal  lease  interests.   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" (or "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 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 on 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  bonds have a wide range of security,
including partially or fully insured mortgages, rent


<PAGE>


subsidized and/or collateralized mortgages, and/or the net revenues from housing
or other public projects.  Some authorities provide further security in the form
of a state's  ability  (without  obligation) to make up deficiencies in the debt
service reserve fund.

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

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

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

      In addition, limitations on the amount of private activity bonds that each
state may issue were revised  downward by the Tax Reform Act,  which has reduced
the supply of such bonds. The value of the Fund's portfolio could be affected if
there is a further 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


<PAGE>


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 based on
a ratio  between the  interest  the Fund  receives  and the total  amount of the
Fund's exempt interest dividends.

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


<PAGE>


      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


<PAGE>


Manager  has  determined  to be  liquid  under  guidelines  set by the  Board of
Directors. Those guidelines require the Manager to evaluate:
     o the frequency of trades and price quotations for such securities;
     o the number of dealers or other potential  buyers willing to purchase
       or sell such securities; o the availability of market-makers; and
     o the nature of the trades for such securities.

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

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

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

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

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


<PAGE>


      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.

      A list of the rating  definitions of Moody's,  S&P and Fitch for municipal
securities  is  contained  in  Appendix  A  to  this   Statement  of  Additional
Information.  Because  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 will 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.  The Fund can invest up to
25% of its total assets in "lower grade" debt securities.  The Fund can do so to
seek current income.  Because lower-rated securities tend to offer higher yields
than investment grade securities,  the Fund can invest in lower grade securities
if the Manager is trying to achieve greater income.

      "Lower-grade" municipal securities include municipal bonds and notes rated
below "investment grade." That includes municipal bonds that have a rating lower
than "Baa" by Moody's or lower than "BBB" by Standard & Poor's or Duff & Phelps,
or similar ratings by other rating  organizations and municipal notes rated SP-2
by Standard & Poor's,  MIG by Moody's or F-2 by Fitch.  While  securities  rated
"Baa" by Moody's or "BBB" by Standard & Poor's are investment  grade and are not
regarded as junk bonds,  those  securities may be subject to special risks,  and
have some speculative  characteristics.  If municipal securities are unrated and
are  determined  by the Manager to be of comparable  quality to debt  securities
rated below  investment  grade,  those municipal  securities are included in the
limitation  on the  percentage  of the Fund's  assets  that can be  invested  in
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.



<PAGE>


     Some of the special credit risks of lower-grade securities are discussed in
the  Prospectus.  There is a greater  risk that the  issuer  may  default on its
obligation to pay interest or to repay  principal than in the case of investment
grade securities.  The issuer's low  creditworthiness may increase the potential
for its  insolvency.  An overall decline in values in the high yield bond market
is also more likely during a period of a general economic downturn.  An economic
downturn or an increase in interest rates could severely  disrupt the market for
high yield bonds, adversely affecting the values of outstanding bonds as well as
the ability of issuers to pay interest or repay principal.  However,  the Fund's
limitations on these  investments  may reduce,  to the Fund's  exposure to those
risks.

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

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

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



<PAGE>


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

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

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

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

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

      On June 29, 1999, the Governor of California  signed the 1999-2000  Budget
Act. The Budget Act  estimated  General  Trust  revenues and  transfers of $63.0
billion, and contained  expenditures totaling $63.7 billion. The Budget Act also
contained expenditures of $16.1 billion from special funds and $1.5 billion from
bond funds.  The  Administration  estimated a budget reserve balance at June 30,
2000,  of  approximately  $881  million.  Not  included  in this  amount  was an
additional  $300 million which (after the Governor's  vetoes) was "set aside" to
provide funds for employee salary increases (to be negotiated in bargaining with
employee unions), and for litigation reserves. The Budget Act anticipates normal
cash flow borrowing during the fiscal year.  Continued State economic  expansion
and large  revenue  increases  enabled the  Governor  and State  legislature  to
provide increases in spending  programs in the 1999-2000 budget.  These included
large increases in education and health and human services funding.

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

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

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

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

      The State  Treasurer's  Office  has  reported  that its  systems  for bond
payments are fully Y2K  compliant.  The State  Controller's  Office has reported
that it has  completed  the  necessary  Y2K  remediation  projects for the State
fiscal and accounting system. Both offices report they are actively working with
outside entities with which they interface to ensure they are also compliant.

      There  can be no  assurance  that  the  steps  taken  by  state  or  local
governments  or agencies to address the Year 2000 problem will be  sufficient to
avoid any adverse impact on their budgets or operations. Therefore, the possible
impact of Year 2000 problems on the debt securities  issued by those governments
and agencies,  and which may be owned by the Trust, cannot be predicted with any
certainty.

Other Investment Techniques and Strategies.  In seeking its objective,  the Fund
can from time to time use the types of  investment  strategies  and  investments
described  below. It is not required to use all of there 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 obligations.

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

      Floating rate and variable  rate demand notes that have a stated  maturity
in excess of one year may have  features  that  permit the holder to recover the
principal amount of the underlying security at specified intervals not exceeding
one year and upon no more than 30 days' notice.  The issuer of that type of note
normally has a corresponding  right in its discretion,  after a given period, to
prepay  the  outstanding  principal  amount of the note plus  accrued  interest.
Generally  the issuer  must  provide a specified  number of days'  notice to the
holder.


<PAGE>


      |X| Inverse Floaters and Other Derivative Investments. The Fund can invest
in inverse  floaters to seek higher  tax-exempt  yields than are available  from
fixed-rate  bonds that have comparable  maturities and credit  ratings.  Inverse
floaters may offer relatively high current income, reflecting the spread between
short-term  and long-term tax exempt  interest  rates.  As long as the municipal
yield curve remains relatively steep and short term rates remain relatively low,
owners  of  inverse  floaters  will have the  opportunity  to earn  interest  at
above-market  rates because they receive  interest at the higher long-term rates
but have paid for bonds with lower short-term rates. If the yield curve flattens
and shifts  upward,  an inverse  floater  will lose  value more  quickly  than a
conventional long-term bond. 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  the  Fund's  exposure  to  changing  security  prices,
interest  rates or other factors that affect the value of  securities.  However,
these  investments  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  investments  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 can 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.  The  Fund  does  not use this  technique  for  speculative
purposes.

      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,  from time to time, the Fund can 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 might  cause a 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 can 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 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  normally  would enter into
"when-issued" or delayed-delivery  purchase  transactions to acquire securities,
the Fund can 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 might incur a gain or loss.

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

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

      |X|  Zero-Coupon  Securities.  The 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.


<PAGE>


      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.  If 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
would 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  might 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.


<PAGE>


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

      In a  repurchase  transaction,  the Fund  acquires  a security  from,  and
simultaneously  resells it to an approved  vendor for delivery on an agreed upon
future  date.  The resale  price  exceeds the  purchase  price by an amount that
reflects an agreed-upon  interest rate effective for the period during which the
repurchase  agreement is in effect.  Approved  vendors  include U.S.  commercial
banks,  U.S.  branches  of  foreign  banks  or  broker-dealers  that  have  been
designated  a primary  dealer in  government  securities,  which meet the credit
requirements set by the Fund's Board of Directors 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.  Because  income  earned  on
repurchase  transactions is not tax-exempt,  under normal market  conditions the
Fund will limit its  repurchase  transactions  to 20% of its total assets.  That
limit  may be  exceeded  if the Fund uses  repurchase  agreements  as  temporary
defensive investments.

      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  could  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  Directors  of the Fund or by the  Manager.  Those
guidelines  take into account the trading  activity for such  securities and the
availability of reliable pricing information, among other factors. If there is a
lack of trading interest in a particular Rule 144A security,  the Fund's holding
of that security may be deemed to be illiquid.


<PAGE>


      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.  The  Fund  can  lend its  portfolio
securities to brokers, dealers and other financial institutions.  The Fund might
do so to raise cash for liquidity purposes.  These loans are limited to not more
than 10% of the value of the Fund's net  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.  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 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 the Fund to reacquire loaned securities on
five days' notice or in time to vote on any important matter.

      |X|  Borrowing.  The Fund can  borrow  up to 10% of the value of its total
assets. It can borrow only as a temporary measure for extraordinary or emergency
purposes.  The Fund cannot make any investment when borrowings  exceed 5% of its
total assets. The Fund can borrow only if it maintains a 300% ratio of assets to
borrowings at all times while a borrowing is  outstanding.  Interest on borrowed
money is an expense the Fund would not  otherwise  incur,  so that it might have
reduced net income during periods of substantial borrowings.

      |X|  Hedging.  The Fund can use  hedging to  attempt  to  protect  against
declines in the market value of the 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:
      o sell interest rate futures or municipal bond index  futures,
      o buy puts on such futures or securities, or


<PAGE>
      o  write covered calls on  securities,  interest rate futures or municipal
         bond  index  futures.  Covered  calls  can  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 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:
      o buy  interest  rate futures or municipal  bond index  futures,  or
      o buy calls on such futures or on securities.

      The Fund is not  obligated  to use hedging  instruments  even though it is
permitted  to use them in the  manager's  discretion,  as described  below.  The
Fund's  strategy  of  hedging  with  futures  and  options  on  futures  will be
incidental to the Fund's  investment  activities in the underlying  cash market.
The particular  hedging  instruments the Fund can use are described  below.  The
Fund can 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 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").

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

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

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

      At any time prior to the  expiration of the future,  the Fund can 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 can  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 can buy and sell certain  kinds of put
options (puts) and call options (calls). These strategies are described below.

     |_| Writing  Covered Call Options.  The Fund can 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)   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.
(3)   The Fund can 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  identifies  on the Fund's books to enable
      it to satisfy its obligations if the call is exercised.

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

      The Fund's  custodian  bank,  or a  securities  depository  acting for the
custodian  bank,  will act as the Fund's escrow agent through the  facilities of
the Options  Clearing  Corporation  ("OCC"),  as to the investments on which the
Fund has written calls traded on exchanges, or as to


<PAGE>


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  can
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 can 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 identifying in escrow
an equivalent  dollar value of liquid assets on the Fund's books.  The Fund will
identify  additional  liquid  assets  on its  books  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 25% 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 can 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  only 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. The Fund can buy a call or put only if, after the purchase, the value of
all call and put options held by the Fund will not exceed 5% of the Fund's total
assets.

      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.



<PAGE>


      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 can buy puts that relate to securities,  broadly-based  municipal
bond indices,  municipal bond index futures or interest rate futures (whether or
not the Fund owns the underlying investment in its portfolio).

      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 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  could 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.


<PAGE>


      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 concluded not to invest in such securities because of
concerns that there might be further market  decline or for other  reasons,  the
Fund would realize a loss on the hedging instruments that would not be 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.  The Fund could
experience  losses if it could not close out a position  because of an  illiquid
market for the future or option.

      |_| 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 could swap a right to receive floating
rate  payments  for fixed rate  payments.  The Fund can enter into swaps only on
securities it owns.  The Fund may not enter into swaps with respect to more than
25% of its total assets. Also, the Fund will identify liquid assets on its


<PAGE>


books (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 can write or hold may be
affected  by  options  written  or  held  by  other  entities,  including  other
investment  companies having the same advisor as the Fund (or an advisor that is
an affiliate of the Fund's  advisor).  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.



<PAGE>


      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:
      o  short-term municipal securities;
      o  obligations  issued or  guaranteed  by the U.S.  government  or its
         agencies or instrumentalities;
      o  short-term debt securities;
      o  repurchase agreements;
      o  commercial  paper rated A-1 by Standard & Poor's,  or a  comparable
         rating by another nationally recognized rating agency;
      o  certificates of deposit of domestic banks with assets of $1 billion or
         more; and
      o  cash equivalents

      |X| Taxable Investments.  While the Fund can invest up to 20% of its total
assets in investments  that generate income subject to income taxes, it does not
anticipate  investing  substantial  amounts of its assets in taxable investments
under normal market  conditions or as part of its normal trading  strategies and
policies. To the extent it invests in taxable securities,  the Fund would not be
able to meet its objective of providing  tax exempt income to its  shareholders.
Taxable  investments  include,  for  example,  hedging  instruments,  repurchase
agreements,  and the  types of  securities  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, a "majority"  vote is defined as the vote of
the holders of the lesser of:
      o  67% or  more  of the  shares  present  or  represented  by  proxy  at a
         shareholder meeting, if the holders of more than 50% of the outstanding
         shares are present or represented by proxy, or
      o  more than 50% of the outstanding shares.

      The Fund's investment  objective is a fundamental  policy.  Other policies
described in the  Prospectus  or this  Statement of Additional  Information  are
"fundamental" only if they are identified as such. The Fund's Board of Directors
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.


<PAGE>


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

   o The Fund cannot concentrate investments.  That means it cannot invest 25%
     or  more  of  its  total  assets  in any  industry.  However,  there  is no
     limitation on investments in municipal  securities,  obligations  issued by
     the State of  California  or its  subdivisions,  agencies,  authorities  or
     instrumentalities,   or  securities   issued  or  guaranteed  by  the  U.S.
     government or its agencies or instrumentalities.  The Fund cannot invest in
     any other securities other than municipal  securities,  temporary defensive
     investments and hedging instruments.

   o The  Fund  cannot  invest  in  interests  in oil or  gas  exploration  or
     development programs or in commodities.  However, the Fund can buy and sell
     any of the hedging instruments  permitted by any of its other policies.  It
     does not matter if the hedging  instrument  is considered to be a commodity
     or commodity contract.

   o The Fund cannot  invest in real estate or in  interests  in real  estate.
     However, the Fund can purchase securities of issuers holding real estate or
     interests in real estate  (including  securities of real estate  investment
     trusts).

   o The Fund cannot purchase securities on margin. However, the Fund can make
     margin  deposits  when using  hedging  instruments  permitted by any of its
     other policies.

   o The Fund cannot invest in companies for the purpose of acquiring  control
     or management of those companies.

   o The Fund cannot  underwrite  securities of other  companies.  A permitted
     exception 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 The Fund cannot  invest in or hold  securities  of any issuer if officers
     and directors of the Fund or the Manager individually beneficially own more
     than 1/2 of 1% of the  securities of that issuer and together own more than
     5% of the securities of that issuer.

   o The Fund cannot invest in other open-end  investment  companies or invest
     more than 5% of its net assets through open market  purchases in closed-end
     investment companies,  including small business investment  companies.  The
     Fund  cannot  make any such  investment  at  commission  rates in excess of
     normal brokerage commissions.

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

   o 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


<PAGE>


     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.

      Unless the Prospectus or this 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. The Fund need not sell securities to meet
the percentage limits if the value of the investment  increases in proportion to
the size of the Fund.

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

      Being  non-diversified  poses additional  investment risks, because if the
Fund  invests  more of its assets in fewer  issuers,  the value of its shares is
subject to greater  fluctuations  from adverse  conditions  affecting any one of
those issuers. However, the Fund does limit its investments in the securities of
any one issuer to qualify for tax purposes as a "regulated  investment  company"
under the Internal Revenue Code. By qualifying,  it does not have to pay federal
income taxes if more than 90% of its earnings are  distributed to  shareholders.
To qualify, the Fund must meet a number of conditions.  First, not more than 25%
of the market value of the Fund's total assets can be invested in the securities
of a single issuer. Second, with respect to 50% of the market value of its total
assets,  (1) not more than 5% of the  market  value of its total  assets  may be
invested in the  securities  of a single  issuer,  and (2) the Fund must not own
more than 10% of the outstanding voting securities of a single issuer.

      The  identification  of the issuer of a municipal  security depends on the
terms and conditions of the security. When the assets and revenues of an agency,
authority,  instrumentality  or other  political  subdivision  are separate from
those of the  government  creating  it and the  security  is backed  only by the
assets and revenues of the subdivision,  agency,  authority or  instrumentality,
the latter would be deemed to be the sole issuer.  Similarly,  if an  industrial
development   bond  is  backed   only  by  the  assets  and   revenues   of  the
non-governmental  user,  then that user  would be deemed to be the sole  issuer.
However,  if in  either  case  the  creating  government  or some  other  entity
guarantees a security, the guarantee would be considered a separate security and
would be treated as an issue of such government or other entity.

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

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

How the Fund is Managed

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

      The Fund's parent  corporation is governed by a Board of Directors,  which
is responsible for protecting the interests of shareholders  under Maryland law.
The  Directors  meet  periodically  throughout  the year to  oversee  the Fund's
activities, review its performance, and review the actions of the Manager.

         |_| Classes of Shares.  The Board of Directors  has the power,  without
shareholder  approval,  to divide  unissued  shares of the Fund into two or more
classes.  The Board  has done so,  and the Fund  currently  has two  classes  of
shares:  Class A and  Class  B.  Both  classes  invest  in the  same  investment
portfolio. Each class of shares:
o     has its own dividends and distributions,
o     pays certain expenses which may be different for the different classes,
o     may have a different net asset value,
o     may have  separate  voting  rights on matters in which  interests  of one
      class are different from interests of another class, and
o     votes as a class on matters that affect that class alone.

      Shares are freely transferable,  and each share of each class has one vote
at shareholder meetings, with fractional shares voting proportionally on matters
submitted  to the vote of  shareholders.  Each share of the Fund  represents  an
interest in the Fund  proportionately  equal to the interest of each other share
of the same class.

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

      |_|  Meetings  of  Shareholders.  Although  the  Fund is not  required  by
Maryland law to hold annual meetings, it may hold shareholder meetings from time
to time on important matters.  The shareholders of the Fund's parent corporation
have the right to call a meeting to remove a Director or to take  certain  other
action described in the Articles of Incorporation or under Maryland law.

      The Fund will  hold  meetings  when  required  to do so by the  Investment
Company  Act or other  applicable  law.  The Fund will  hold a meeting  when the
Directors call a meeting or upon proper request of  shareholders.  If the Fund's
parent corporation  receives a written request of the record holders of at least
25% of the  outstanding  shares  eligible  to be  voted at a  meeting  to call a
meeting for a specified purpose (which might include the removal of a Director),
the Directors will call a meeting of  shareholders  for that specified  purpose.
The Fund's parent  corporation  has undertaken that it will then either give the
applicants  access  to the  Fund's  shareholder  list  or mail  the  applicants'
communication to all other shareholders at the applicants' expense.


<PAGE>


      Shareholders of the Fund and of its parent corporation's other series vote
together in the aggregate on certain matters at  shareholders'  meetings.  Those
matters include the election of Directors and ratification of appointment of the
independent  auditors.  Shareholders  of  a  particular  series  or  class  vote
separately  on  proposals  that affect that series or class.  Shareholders  of a
series or class that is not  affected by a proposal  are not entitled to vote on
the proposal.  For example, only shareholders of a particular series vote on any
material amendment to the investment  advisory  agreement for that series.  Only
shareholders of a particular class of a series vote on certain amendments to the
Distribution and/or Service Plans if the amendments affect only that class.

1.  For the 1998 calendar year.
2.  Mr. Bowen did not receive compensation during the 1998 calendar year because
    he was affiliated with the Manager during that period.

|X| Deferred  Compensation  Plan.  The Board of Directors has adopted a Deferred
Compensation  Plan for  disinterested  directors  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 Director
is  periodically  adjusted as though an  equivalent  amount had been invested in
shares of one or more  Oppenheimer  funds  selected by the Director.  The amount
paid  to the  Director  under  the  plan  will  be  determined  based  upon  the
performance of the selected funds.

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

      o Major  Shareholders.  As of  December  10, 1999 there are no persons who
owned of record or where known by the Fund to own beneficially 5% or more of any
class of the Fund's outstanding shares.


<PAGE>


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.

      |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 portfolio. Other members
of the Manager's Fixed Income Portfolio Department provide the portfolio manager
with counsel and support in managing the Fund's portfolio.

      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  administration for the Fund.
Those  responsibilities  include the compilation and maintenance of records with
respect to its operations,  the preparation and filing of specified reports, and
composition of proxy materials and registration statements for continuous public
sale of shares of the Fund.

      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, brokerage commissions,
fees to certain Directors, legal and audit expenses, custodian bank and transfer
agent expenses,  share issuance costs,  certain printing and registration  costs
and non-recurring expenses, including litigation costs.

      Under the investment advisory  agreement,  the Manager is paid a fee based
on the average  annual net assets of the Fund. The rates at which the Manager is
paid depend on the amount of the Fund's average annual net assets:
      o  When net  assets  are less than $25  million,  no fee is paid to the
         Manager.
      o  When net assets are $25  million or more but less than $50  million,
         the rate of the fee is 0.15% of average annual net assets.
      o  When net assets are $50 million or more but less than $75 million, the
         rate of the fee is 0.25% of average annual net assets.
      o  When net assets are $75 million or more but less that $100 million, the
         rate of the is 0.40% of average annual net assets.
      o  When net assets are $100 million or more, the rate is 0.55% of average
         annual net assets.


<PAGE>


      Apart from the investment advisory  agreement,  the Manager previously had
voluntarily  agreed to waive a portion  of its fee,  so that when the Fund's net
assets are $100 million or more,  the  Manager's fee was paid at a rate of 0.40%
of average annual net assets. The Manager withdrew that waiver on April 1, 2000.
The management fees paid by the Fund to the Manager are applied to the aggregate
assets of the Fund.  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 in the last three  fiscal years
are shown in the chart 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 of its obligations and duties under the investment  advisory
agreement,  the  Manager is not liable  for any loss the Fund  sustains  for any
investment,  adoption  of any  investment  policy,  or  the  purchase,  sale  or
retention of any security.

      The  agreement  permits the Manager to act as  investment  advisor for any
other person,  firm or corporation and to use the names  "Oppenheimer" and "Main
Street" in connection  with other  investment  companies for which it may act as
investment advisor or general distributor. If the Manager shall no longer act as
investment advisor to the Fund, the Manager may withdraw the right of the Fund's
parent  corporation to use the names  "Oppenheimer" and "Main Street" as part of
its name and the name of the Fund.

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. The Manager may
employ broker-dealers that the Manager thinks, in its 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 Directors.

      Under the investment  advisory  agreement,  the Manager may select brokers
(other than affiliates) that provide  brokerage and/or research services for the
Fund and/or the other  accounts  over which the Manager or its  affiliates  have
investment  discretion.  The commissions paid to such brokers may be higher than
another qualified broker would charge, if the Manager makes a


<PAGE>


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 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.  If two or more of funds  advised  by the
Manager  purchase the same  security on the same day from the same  dealer,  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 Directors  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


<PAGE>


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.

Distribution and Service Plans

The  Distributor.  Under its  General  Distributor's  Agreement  with the Fund's
parent corporation,  the Distributor acts as the Fund's principal underwriter in
the  continuous  public  offering of the Fund's shares.  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 during the Fund's three most recent fiscal
years is shown 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,"
below.

Distribution  and Service Plan. The Fund has adopted a Distribution  and Service
Plan for Class B shares Rule 12b-1 of the Investment Company Act. Under the plan
the Fund  reimburses the  Distributor for all or a portion of its costs incurred
in connection with the distribution and/or servicing of Class B shares.


<PAGE>


      The plan has been approved by a vote of the Board of Directors,  including
a majority of the Independent Directors2, cast in person at a meeting called for
the purpose of voting on that plan. The  shareholder  vote for the  Distribution
and Service Plans for Class B shares was cast by the Manager as the sole initial
holder of Class B shares of the Fund.
2  In  accordance  with Rule 12b-1 of the  Investment  Company Act, the term
   "Independent  Directors" in this Statement of Additional Information refers
   to those  Directors  who are not  "interested  persons" of the Fund (or its
   parent  corporation)  and who do not have any direct or indirect  financial
   interest in the operation of the  distribution  plan or any agreement under
   the plan.

      Under the plans,  the Manager  and the  Distributor  may make  payments to
affiliates and, 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 its profits from the advisory fee it receives
from the Fund. In their sole  discretion,  the  Distributor  and the Manager may
increase or decrease the amount of payments  they make from their own  resources
to plan recipients.

      Unless the plan is terminated as described  below,  the plan  continues in
effect  from  year to year but only if the  Fund's  Board of  Directors  and its
Independent  Directors  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.  The plan may be  terminated at any time by the
vote of a majority of the Independent Directors or by the vote of the holders of
a "majority" (as defined in the Investment Company Act) of the outstanding Class
B shares.

      The Board of  Directors  and the  Independent  Directors  must approve all
material  amendments to the plan. An amendment to increase materially the amount
of payments to be made under the plan must be approved by  shareholders of Class
B.

      While the plan is in  effect,  the  Treasurer  of the Fund  shall  provide
written reports on the plan to the Board of Directors at least quarterly for its
review.  The Reports shall detail the amount of all payments made under the plan
and the purpose for which the payments  were made.  Those reports are subject to
the review and approval of the Independent Directors.

      The plan states that while it is in effect,  the selection and  nomination
of those  Directors of the Fund's  parent  corporation  who are not  "interested
persons" of the  corporation (or the Fund) is committed to the discretion of the
Independent  Directors.  This 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 Directors.

      Under the plan, 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 Independent  Directors.  The Board of
Directors has set no minimum  amount of assets to qualify for payments under the
plan.



<PAGE>


            |_| Class B Service  and  Distribution  Plan  Fees.  Under the plan,
service fees and distribution  fees are computed on the average of the net asset
value of Class B shares, determined as of the close of each regular business day
during the period.  The plan allows the  Distributor  to be  reimbursed  for its
services and costs in distributing Class B shares and servicing accounts.

     Under the  service  plan,  the  services  provided by  recipients  to their
customers  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 service  plan permits  reimbursements  to the
Distributor at a rate of up to 0.25% of average annual net asset of Class B. The
Board has set the rate at that level.

      The plan  permits the  Distributor  to retain both the  asset-based  sales
charges and the service fees or to pay recipients the service fee on a quarterly
basis, without payment in advance. However, the Distributor currently intends to
pay the service fee to recipients in advance for the first year after the shares
are  purchased.  After the first year shares are  outstanding,  the  Distributor
makes  service fee payments  quarterly on those shares.  The advance  payment is
based on the net asset value of shares sold. Shares purchased by exchange do not
qualify for the service fee payment.  If Class B 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 of the service fee made on those shares.

      The Distributor retains the asset-based sales charge on Class B shares. If
a dealer has a special agreement with the Distributor,  the Distributor will pay
the Class B service fee and the asset-based sales charge to the dealer quarterly
in lieu of paying the sales  commissions  and service fee in advance at the time
of purchase.

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

    The Distributor's actual expenses in selling Class B 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 the  Class B plan is
terminated  by the Fund,  the Board of Directors  may allow the Fund to continue
payments of the asset-based sales charge to the Distributor for


<PAGE>


distributing shares before the plan was terminated. All payments under the Class
B plan is subject to the limitation imposed by the Conduct Rules of the National
Association of Securities Dealers, Inc. on payments of asset-based sales charges
and service fees.

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 the Fund's 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
www.oppenheimerfunds.com.

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

      Use of  standardized  performance  calculations  enables  an  investor  to
compare the Fund's  performance  to the  performance of other funds for the same
periods.  However,  a number of factors  should be  considered  before using the
Fund's performance information as a basis for comparison with other investments:

      o Yields and total  returns  measure  the  performance  of a  hypothetical
account in the Fund over various periods and do not show the performance of each
shareholder's  account.  Your  account's  performance  will  vary from the model
performance  data if your  dividends  are  received in cash,  or you buy or sell
shares  during the period,  or you bought  your  shares at a different  time and
price than the shares used in the model.


<PAGE>


      o An  investment  in the  Fund is not  insured  by the  FDIC or any  other
government agency.
      o The  principal  value of the  Fund's  shares,  and its  yields and total
returns are not guaranteed and normally will fluctuate on a daily basis.
      o When an investor's  shares are redeemed,  they may be worth more or less
than their original cost.
      o Yields and total returns for any given past period represent  historical
performance information and are not, and should not be considered,  a prediction
of future yields or returns.

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

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

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

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

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

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

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

<PAGE>


      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 shares is the net
asset value per share,  without  considering  the effect of contingent  deferred
sales charges.  The Class A dividend yield may also be quoted without  deducting
the maximum initial sales charge.

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

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

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

     |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


<PAGE>


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.

      |_| 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 or Class B shares.  Each is based
on the  difference  in net asset value per share at the beginning and the end of
the  period  for a  hypothetical  investment  in that  class of shares  (without
considering  front-end  or  contingent  deferred  sales  charges) and takes into
consideration the reinvestment of dividends and capital gains distributions.

"Life-of-Class"  return  for Class B shares  uses  Class A  performance  for the
period after conversion.


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 classes of 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  California  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.

         |_|  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 included in the municipal bond category.

      Morningstar  proprietary  star ratings  reflect  historical  risk-adjusted
total investment return.  Investment return measures a fund's (or class's) one-,
three-,  five- and ten-year  average  annual  total  returns  (depending  on the
inception of the fund or class) in excess of 90-day U.S.  Treasury  bill returns
after considering the fund's sales charges and expenses.  Risk 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 fund in the fund's  category.  Five stars is the "highest"
rating (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)  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 ranking (weighted 40%/30%/30%,  respectively),  depending on
the  inception  date of the fund (or  class).  Ratings  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  percentages  from one percent to one hundred  percent and are not
risk adjusted. For example if a fund is in the 94th percentile,  that means that
94% of the funds in the same category performed better than it did.

         |_|  Performance   Rankings  and  Comparisons  by  Other  Entities  and
Publications.  From time to time the Fund may include in its  advertisements and
sales literature performance  information about the Fund cited in newspapers and
other periodicals such as The New York Times, The Wall Street Journal, Barron's,
or similar  publications.  That information may include  performance  quotations
from other sources,  including  Lipper and  Morningstar.  The performance of the
Fund's classes of 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  returns to the return on
fixed-income  investments  available from banks and thrift  institutions.  Those
include certificates of deposit,  ordinary  interest-paying checking and savings
accounts,  and other forms of fixed or variable time deposits, and various other
instruments such as Treasury bills.  However, the Fund's returns and share price
are not guaranteed or insured by the FDIC or any other agency and will fluctuate
daily,  while  bank  depository  obligations  may be insured by the FDIC and may
provide fixed rates of return. Repayment of principal and payment of interest on
Treasury  securities  is  backed  by the  full  faith  and  credit  of the  U.S.
government.

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

How to Buy Shares

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


<PAGE>


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:
      o  Class A and Class B shares you purchase for your  individual  accounts,
         or for your  joint  accounts,  or for trust or  custodial  accounts  on
         behalf of your children who are minors, and
      o  current  purchases  of Class A and Class B shares of the Fund and other
         Oppenheimer  funds to reduce  the sales  charge  rate that  applies  to
         current purchases of Class A shares, and
      o  Class  A and  Class  B  shares  of  Oppenheimer  funds  you  previously
         purchased subject to an initial or contingent  deferred sales charge to
         reduce the sales  charge rate for current  purchases of Class A shares,
         provided that you still hold your  investment in one of the Oppenheimer
         funds.

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

      |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:

                                          Oppenheimer Main Street California

Centennial California Tax Exempt Trust    Centennial Tax Exempt Trust
Centennial Government Trust               Oppenheimer Cash Reserves
Centennial Money Market Trust             Oppenheimer Money Market Fund, Inc.

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

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

     A Letter of Intent is an investor's statement in writing to the Distributor
of the intention to purchase Class A shares or Class A and Class B shares of the
Fund (and other  Oppenheimer  funds)  during a 13-month  period (the  "Letter of
Intent period").  At the investor's request,  this may include purchases made up
to 90 days prior to the date of the  Letter.  The Letter  states the  investor's
intention to make the aggregate amount of purchases of shares which,  when added
to the  investor's  holdings of shares of those funds,  will equal or exceed the
amount specified in the


<PAGE>


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 bound 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.

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



<PAGE>


      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  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.


<PAGE>
     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 only
available if your bank is an ACH member.  Asset Builder Plans may not be used to
buy  shares  for  OppenheimerFunds  employer -  sponsored  qualified  retirement
accounts.  Asset  Builder Plans also enable  shareholders  of  Oppenheimer  Cash
Reserves to use their fund account to make monthly automatic purchases of shares
of up to four other Oppenheimer funds.

      If you make  payments  from your bank  account to  purchase  shares of the
Fund, your bank account will be debited automatically. Normally the debt will be
made two  business  days  prior to the  investment  dates you  selected  in 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) 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 the Asset  Builder  payment or you can
terminate these 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
shares  and  the  dividends  payable  on  Class B  shares  will  be  reduced  by
incremental  expenses  borne solely by that class.  Those  expenses  include the
asset-based sales charges to which Class B is subject.

      The  availability  of different  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
shares have no initial  sales charge,  the purpose of the deferred  sales charge
and  asset-based  sales  charge  on  Class B  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


<PAGE>


Fund. A salesperson who is entitled to receive compensation from his or her firm
for selling Fund shares may receive different levels of compensation for selling
one class of shares rather than another.

      The  Distributor  will not accept any order in the amount of  $500,000  or
more for Class B 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  shareholder  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  shareholder,  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 bank fees, Directors' fees, transfer agency fees,
legal fees and auditing costs.  Those expenses are paid out of the Fund's assets
and are not paid directly by  shareholders.  However,  those expenses reduce the
net asset value of shares,  and therefore are indirectly  borne by  shareholders
through their investment.

      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
Directors,  custodian bank  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.  The
calculation is done by dividing the value of the Fund's net assets  attributable
to a class by the  number of  shares of that  class  that are  outstanding.  The
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).


<PAGE>


The  Exchange's  most recent  annual  announcement  (which is subject to change)
states  that it will close on New Year's Day,  Presidents'  Day,  Martin  Luther
King,  Jr.  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 certain
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 value of some of the Fund's
portfolio  securities may change  significantly on those days, when shareholders
may not purchase or redeem shares.

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

      o Long-term debt  securities  having a remaining  maturity in excess of 60
days  are  valued  based  on the mean  between  the  "bid"  and  "asked"  prices
determined  by a  portfolio  pricing  service  approved  by the Fund's  Board of
Directors  or  obtained  by the  Manager  from two active  market  makers in the
security on the basis of reasonable inquiry.
      o The  following  securities  are valued at the mean between the "bid" and
"asked" prices  determined by a pricing service  approved by the Fund's Board of
Directors  or  obtained  by the  Manager  from two active  market  makers in the
security on the basis of reasonable inquiry:
     (1) debt  instruments  that  have a  maturity  of more  than 397 days  when
     issued,
     (2) debt  instruments  that had a maturity  of 397 days or less when issued
     and have a remaining maturity of more than 60 days, and
     (3) non-money  market debt  instruments  that had a maturity of 397 days or
     less when issued and which have a remaining maturity of 60 days or less.
     o The following  securities are valued at cost,  adjusted for amortization
of premiums and accretion of discounts:
     (1) money market debt securities held by a non-money market fund that had a
     maturity of less than 397 days when  issued that have a remaining  maturity
     of 60 days or less, and
     (2) debt  instruments  held by a money  market  fund that have a  remaining
     maturity of 397 days or less.
     o    Securities    (including    restricted    securities)    not   having
readily-available  market  quotations are valued at fair value  determined under
the Board's procedures.

      If the  Manager  is unable to locate  two  market  makers  willing to give
quotes,  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 Directors. 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.


<PAGE>


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 Directors 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

Information on how to sell shares of the Fund is stated in the  Prospectus.  The
information  below  provides  additional  information  about the  procedures and
conditions for redeeming shares.

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)

<PAGE>
     specifically  acknowledges  that if they  choose  to  permit  checks to be
     honored if there is a single  signature on checks drawn  against  joint
     accounts, or accounts for corporations,  partnerships,  trusts or other
     entities,  the  signature  of any  one  signatory  on a  check  will be
     sufficient to authorize  payment of that check and redemption  from the
     account,  even if that account is  registered in the names of more than
     one  person  or more  than  one  authorized  signature  appears  on the
     Checkwriting card or the Application, as applicable;
     (5)  understands  that the  Checkwriting  privilege  may be  terminated  or
     amended at any time by the Fund and/or the Fund's bank; and
     (6)  acknowledges and agrees that neither the Fund nor its bank shall incur
     any liability for that amendment or termination of checkwriting  privileges
     or for  redeeming  shares to pay checks  reasonably  believed by them to be
     genuine,  or for returning or not paying checks that have not been accepted
     for any reason.

Reinvestment Privilege.  Within six months of a redemption, a shareholder may
reinvest all or part of the redemption proceeds of:
      o  Class A shares purchased  subject to an initial sales charge or Class A
         shares on which a contingent deferred sales charge was paid, or
      o  Class B shares  that were  subject to the Class B  contingent  deferred
         sales charge when redeemed.

      The  reinvestment  may be made without sales charge only in Class A shares
of the Fund or any of the other  Oppenheimer funds into which shares of the Fund
are  exchangeable as described in "How to Exchange  Shares" below.  Reinvestment
will be at the net asset value next computed  after the Transfer  Agent receives
the  reinvestment  order.  The shareholder  must ask the Transfer Agent for that
privilege  at the time of  reinvestment.  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 Directors 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.


<PAGE>


      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 Directors  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 $500 or such lesser  amount as the
Board may fix. The Board 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
contingent  deferred sales charge will be followed in  determining  the order in
which shares are transferred.

Sending  Redemption  Proceeds by Wire.  The wire of  redemption  proceeds may be
delayed if the Fund's  custodian bank is not open for business on a day when the
Fund would normally  authorize the wire to be made,  which is usually the Fund's
next regular business day following the redemption. In those circumstances,  the
wire will not be transmitted  until the next bank business day on which the Fund
is open for  business.  No  dividends  will be paid on the  proceeds of redeemed
shares awaiting transfer by wire.

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


<PAGE>


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.

      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
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).

      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


<PAGE>


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.


<PAGE>


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

<PAGE>
     Shares of Oppenheimer  Capital  Preservation  Fund may not be exchanged for
     shares of Oppenheimer Money Market Fund, Inc., Oppenheimer Cash Reserves or
   o Oppenheimer  Limited-Term  Government Fund. Only  participants in certain
     retirement  plans may purchase shares of Oppenheimer  Capital  Preservation
     Fund, and only those  participants may exchange shares of other Oppenheimer
     funds for shares of Oppenheimer Capital Preservation Fund.

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

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

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

      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.

      When Class B shares are  redeemed to effect an  exchange,  the  priorities
described in "How To Buy Shares" in the  Prospectus  for the  imposition  of the
Class B contingent  deferred  sales charge will be followed in  determining  the
order in which the shares are exchanged.  Before exchanging shares, shareholders
should take into account how the exchange may affect any


<PAGE>


contingent  deferred  sales  charge  that  might be  imposed  in the  subsequent
redemption  of remaining  shares.  Shareholders  owning  shares of more than one
Class must specify whether they intend to exchange Class A or Class B 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 investor 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.

         |_| 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 you 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, 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 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 shares.  Those dividends will also differ in amount as a
consequence  of any  difference  in net asset  value  among  Class A and Class B
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.


<PAGE>


      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:  certain  taxable  temporary
investments (such as certificates of deposit, repurchase agreements,  commercial
paper   and   obligations   of   the   U.S.   government,   its   agencies   and
instrumentalities);  (1) income from securities  loans; (2) income or gains from
options or futures;  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.

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


<PAGE>


invested  in such  obligations  at the  close of each  quarter  in its tax year.
Distributions  from the Fund  attributable  to income  from  sources  other than
California municipal  securities and U.S. government  obligations will generally
be subject to California income tax as ordinary income.

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

      Under the Internal  Revenue  Code,  by December 31 each year the Fund must
distribute  98% of its taxable  investment  income earned from January 1 through
December  31 of that year and 98% of its  capital  gains  realized in the period
from November 1 of the prior year through  October 31 of the current year. If it
does not, the Fund must pay an excise tax on the amounts not distributed.  It is
presently  anticipated that the Fund will meet those requirements.  However, the
Fund's Board of Directors 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  without  sales  charge at the net  asset  value per share in effect at the
close of business on the payable date of the dividend or distribution.  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 first must obtain a prospectus for that fund and an application from
the Distributor to establish an account.  Dividends  and/or  distributions  from
shares of certain other Oppenheimer funds (other than Oppenheimer Cash Reserves)
may be invested in shares of this Fund on the same basis.


Additional Information About the Fund

The 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.


<PAGE>


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

INDEPENDENT AUDITORS' REPORT

=============================================================================
TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF OPPENHEIMER MAIN STREET CALIFORNIA
MUNICIPAL FUND:

We have audited the accompanying statement of assets and liabilities,  including
the statement of investments,  of Oppenheimer Main Street  California  Municipal
Fund as of August 31, 1999,  the related  statement of  operations  for the year
then ended,  the  statements of changes in net assets for the years ended August
31, 1999 and 1998 and the financial  highlights  for the period July 1, 1994, to
August 31, 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  confirmation  of securities  owned as of
August 31, 1999, by correspondence with the custodian and brokers; where replies
were not received from brokers, we performed other auditing procedures. An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

        In our opinion,  such  financial  statements  and  financial  highlights
present fairly, in all material respects,  the financial position of Oppenheimer
Main Street California  Municipal Fund as of August 31, 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 $16,128,362 or 11.58% of the
Fund's net assets as of August 31, 1999.

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

3. Securities with an aggregate market value of $559,992 are held in
collateralized accounts to cover initial margin requirements on open futures
sales contracts. See Note 5 of Notes to Financial Statements.

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

5.  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
Directors.  These  securities  amount to  $4,165,800  or 2.99% of the Fund's net
assets as of August 31, 1999.

AS OF AUGUST 31, 1999,  SECURITIES SUBJECT TO THE ALTERNATIVE MINIMUM TAX AMOUNT
TO $34,930,607 OR 25.07% OF THE FUND'S NET ASSETS.

NOTES TO FINANCIAL STATEMENTS

===============================================================================
1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer  Main  Street  California  Municipal  Fund (the  Fund) is a separate
series of Oppenheimer Main Street Funds, Inc., an open-end management investment
company  registered  under the Investment  Company Act of 1940, as amended.  The
Fund's investment  objective is to seek as high a level of current income exempt
from federal and California personal 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 and  Class B shares.  Class A shares  are sold  with a  front-end  sales
charge on  investments  up to $1  million.  Class B 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 and B 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 Directors. Such securities which cannot be valued by an
approved portfolio pricing service are valued using  dealer-supplied  valuations
provided the Manager is satisfied that the firm rendering the quotes is reliable
and  that  the  quotes  reflect  current  market  value,  or  are  valued  under
consistently  applied  procedures  established  by the  Board  of  Directors  to
determine  fair  value  in good  faith.  Short-term  "money  market  type"  debt
securities having a remaining maturity of 60 days or less are valued at cost (or
last  determined  market  value)  adjusted for  amortization  to maturity of any
premium or  discount.  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.

Notes to Financial Statements continued

===============================================================================
1. SIGNIFICANT ACCOUNTING POLICIES Continued

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.

- -------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date.

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

- -------------------------------------------------------------------------------
EXPENSE OFFSET ARRANGEMENTS. Expenses paid indirectly represent a reduction of
custodian fees for earnings on cash balances maintained by the Fund.

- -------------------------------------------------------------------------------
OTHER.  Investment  transactions  are accounted  for as of trade date.  Original
issue  discount is accreted and premium is amortized in accordance  with federal
income tax  requirements.  For municipal bonds acquired after April 30, 1993, on
disposition or maturity,  taxable ordinary income is recognized to the extent of
the lesser of gain or market  discount  that would have accrued over the holding
period. Realized gains and losses on investments and unrealized appreciation and
depreciation are determined on an identified cost basis, which is the same basis
used for federal income tax purposes.

      There are certain  risks  arising  from  geographic  concentration  in any
state.  Certain revenue- or tax-related events in a state may impair the ability
of certain  issuers of municipal  securities  to pay  principal  and interest on
their obligations.

      The  preparation  of financial  statements  in conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements and the reported  amounts of income and expenses during the reporting
period. Actual results could differ from those estimates.

$4,093,192.

===============================================================================
4. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

MANAGEMENT FEES. Management fees paid to the Manager were in accordance with the
investment advisory agreement with the Fund which provides for a fee of 0.55% of
average  annual net assets if the Fund's net assets are $100 million or more (it
is reduced if assets are less). The Manager has voluntarily  undertaken to limit
its fees to 0.40% of average  annual  net  assets if the Fund's  assets are $100
million or more.  The Manager can terminate  that waiver at any time. The Fund's
management  fee for the year ended  August 31, 1999 was 0.40% of average  annual
net assets for each class of shares, after giving affect to the waiver.

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

- -------------------------------------------------------------------------------
DISTRIBUTION  AND SERVICE PLAN FEES. Under its General  Distributor's  Agreement
with the Manager,  the Distributor acts as the Fund's  principal  underwriter in
the continuous public offering of the different classes of shares of the Fund.

</TABLE>


      The Fund has adopted a  Distribution  and Service  Plan for Class B 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 B 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 plan allows the Distributor to be reimbursed for
its services and costs in distributing Class B and servicing accounts.

      The Distributor  retains the  asset-based  sales charge on Class B shares.
The  asset-based  sales charges on Class B 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 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 plan.  If the Class B
plan is  terminated  by the Fund,  the Board of Directors  may allow the Fund to
continue  payments  of the  asset-based  sales  charge  to the  Distributor  for
distributing  shares  before the plan was  terminated.  The plan  allows 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  August 31, 1999
were as follows:

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

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

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

      Securities  held  in  collateralized  accounts  to  cover  initial  margin
requirements   on  open  futures   contracts  are  noted  in  the  Statement  of
Investments.  The  Statement  of Assets and  Liabilities  reflects a  receivable
and/or payable for the daily mark to market for variation margin.

      Risks of entering into futures contracts (and related options) include the
possibility  that there may be an illiquid market and that a change in the value
of the  contract or option may not  correlate  with  changes in the value of the
underlying securities.

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

6. BANK BORROWINGS

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

      The Fund had no  borrowings  outstanding  during the year ended August 31,
1999.

- --------------------------------------------------------------------------------
                               RATINGS DEFINITIONS
- --------------------------------------------------------------------------------

Below are summaries of the rating definitions used by the  nationally-recognized
rating agencies listed below.  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 (Taxable) 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.


<PAGE>


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.

Short-Term Ratings - Taxable Debt

These  ratings apply to the ability of issuers to repay  punctually  senior debt
obligations having an original maturity not exceeding one year:

Prime-1: Issuer has a superior ability for repayment of senior short-term debt
obligations.

Prime-2:  Issuer has a strong  ability for repayment of senior  short-term  debt
obligations.  Earnings  trends  and  coverage,  while  sound,  may be subject to
variation.  Capitalization  characteristics,  while  appropriate,  may  be  more
affected by external conditions. Ample alternate liquidity is maintained.

Prime-3:  Issuer has an acceptable  ability for  repayment of senior  short-term
obligations.  The effect of industry characteristics and market compositions may
be more  pronounced.  Variability  in earnings and  profitability  may result in
changes in the level of debt protection  measurements and may require relatively
high financial leverage. Adequate alternate liquidity is maintained.

Not Prime: Issuer does not fall within any Prime rating category.

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.


<PAGE>


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.

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.


<PAGE>


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."3 This waiver provision applies to:
3   However,  that  commission  will not be paid on  purchases  of shares in
    amounts of $1 million or more  (including any right of  accumulation)  by a
    Retirement Plan that pays for the purchase with the redemption  proceeds of
    Class C shares of one or more  Oppenheimer  funds held by the Plan for more
    than one year.




     |_|  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

         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.
