The Trust's Investment Objective and Strategies


WHAT IS THE TRUST'S  INVESTMENT  OBJECTIVE?  The Trust seeks the maximum current
interest  income exempt from federal and  California  personal  income taxes for
individual investors as is consistent with the preservation of capital.


WHAT DOES THE TRUST INVEST IN? The Trust is a money market fund. It invests in a
variety of high-quality  money market  instruments to seek income.  Money market
instruments are short-term,  U.S.  dollar-denominated debt instruments issued by
the  U.S.   government,   domestic  and  foreign   corporations   and  financial
institutions and other entities.  They include,  for example,  bank obligations,
repurchase  agreements,  commercial paper,  other corporate debt obligations and
government debt  obligations.  To be considered  "high-quality,"  generally they
must be rated in one of the two highest credit-quality categories for short-term
securities by nationally recognized rating services. If unrated, a security must
be determined by the Trust's  investment  manager to be of comparable quality to
rated securities.

      The Trust  normally  attempts  to invest  100% of its assets in  municipal
securities  and at  least  65% of its  assets  in  obligations  of the  State of
California and its political  subdivisions,  agencies and  instrumentalities  or
obligations of commonwealths  or territories of the United States,  the interest
from which is not subject to  California  personal  income tax in the opinion of
bond counsel to the respective  issuer. As a fundamental  policy, the Trust will
not make any  investment  that will reduce the portion of its total  assets that
are  invested  in  municipal  securities  to less than 80%. . The Trust will not
invest  more than 20% of its net assets in  municipal  securities  the income on
which may be a tax preference item that would increase an individual  investor's
alternative minimum tax.

WHO IS THE TRUST  DESIGNED  FOR? The Trust is designed for investors who want to
earn income at current  money market rates while  preserving  the value of their
investment,  because the Trust  tries to keep its share  price  stable at $1.00.
Income on short-term money market  instruments  tends to be lower than income on
longer term debt securities,  so the Trust's yield will likely be lower than the
yield on  longer-term  fixed  income  funds.  The Trust  does not invest for the
purpose  of  seeking  capital  appreciation  or  gains  and  is  not a  complete
investment program.


Main Risks of Investing in the Trust


All  investments  carry  risks  to  some  degree.  Funds  that  invest  in  debt
obligations  for income may be subject to credit risks and interest  rate risks.
However,  the Trust's investments must meet strict standards set by its Board of
Trustees  following  rules for money  market  funds  under  federal  law.  Those
standards  include  requirements  for  maintaining  high  credit  quality in the
Trust's  portfolio,  a short average portfolio maturity to reduce the effects of
changes in interest  rates on the value of the Trust's  securities and investing
in a wide  variety  of  issuers  to reduce  the  effects of a default by any one
issuer on the Trust's overall portfolio and the value of the Trust's shares.

      Even so, there are risks that any of the Trust's  holdings  could have its
credit rating  downgraded,  or the issuer could default,  or that interest rates
could rise sharply,  causing the value of the Trust's investments (and its share
price) to fall. As a result,  there is a risk that the Trust's shares could fall
below  $1.00 per share.  If there is a high  redemption  demand for the  Trust's
shares  that was not  anticipated,  portfolio  securities  might have to be sold
prior to their  maturity  at a loss.  Also,  there is the risk that the value of
your investment could be eroded over time by the effects of inflation,  and that
poor security  selection could cause the Trust to underperform  other funds with
similar objectives.


Risks of  Non-Diversification -- Investments in California Municipal Securities.
      The Trust is "non-diversified." That means that compared to funds that are
      diversified,  it  can  invest  a  greater  portion  of its  assets  in the
      securities of one issuer, such as bonds issued by the State of California.
      Having a higher  percentage  of its assets  invested in the  securities of
      fewer issuers,  particularly obligations of government issuers of a single
      state, could result in greater credit risk exposure to a smaller number of
      issuers due to economic,  regulatory or political  problems in California.
      However,  the  Trust  is  currently  subject  to  certain  diversification
      requirements under rules for money market funds under federal law.

- -------------------------------------------------------------------------------
An investment  in the Trust is not insured or guaranteed by the Federal  Deposit
Insurance  Corporation or any other government agency.  Although the Trust seeks
to preserve the value of your  investment at $1.00 per share,  it is possible to
lose money by investing in the Trust.
- --------------------------------------------------------------------------------


      The Trust's investment  manager,  Centennial Asset Management  Corporation
(referred  to in this  Prospectus  as the  Manager)  tries  to  reduce  risks by
carefully  researching  investments  before the Trust buys them. The rate of the
Trust's  income  will  vary from day to day,  generally  reflecting  changes  in
overall  short-term  interest  rates.  There is no assurance that the Trust will
achieve its investment objective.


The Trust's Past Performance


The bar chart and table below show how the  Trust's  returns may vary over time,
by showing changes in the Trust's performance from year to year for the calendar
years since the Trust's  inception  and average  annual total returns for the 1-
and 5- year  periods  and the life of the Trust.  Variability  of returns is one
measure of the risks of  investing  in a money  market  fund.  The Trust's  past
investment  performance  does not  predict  how the Trust  will  perform  in the
future.


Annual Total Returns (as of 12/31 each year)

[See appendix to prospectus for annual total return data for bar chart.]


For the period from 1/1/99  through  9/30/99 the  cumulative  total  return (not
annualized)  was 1.78%.  During the period  shown in the bar chart,  the highest
return  (not  annualized)  for a calendar  quarter was 0.98% (2nd Q '91) and the
lowest return (not annualized) for a calendar quarter was 0.42% (1st Q '94).

Fees and Expenses of the Trust


The  Trust  pays a variety  of  expenses  directly  for  investment  management,
administration  and other  services.  Those  expenses  are  subtracted  from the
Trust's  assets to  calculate  the  Trust's  net  asset  value  per  share.  All
shareholders  therefore pay those expenses indirectly.  The following tables are
meant to help you  understand  the fees and  expenses you may pay if you buy and
hold shares of the Trust.  The numbers below are based upon the Trust's expenses
during its fiscal year ended June 30, 1999.

SHAREHOLDER  FEES.  The Trust does not charge any  initial  sales  charge to buy
shares or to reinvest  dividends.  There are no exchange fees or redemption fees
and no  contingent  deferred  sales  charges  (unless  you buy  Trust  shares by
exchanging Class A shares of other eligible funds that were purchased subject to
a contingent deferred sales charge, as described in "How to Sell Shares").


Annual Trust Operating Expenses (deducted from Trust assets):
(% of average daily net assets)

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

 Management Fees                              0.50%

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

 Distribution and/or Service (12b-1) Fees     0.20%

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

 Total Annual Operating Expenses              0.80%

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

"Other expenses" include transfer agent fees, custodial fees, and accounting and
legal  expenses  the Trust pays.  The "Total  Annual  Operating  Expenses"  were
reduced by a voluntary expense assumption  undertaken by the Manager.  With that
expense  assumption,  the  "Management  Fees" and the  "Total  Annual  Operating
Expenses" were 0.48%, 0.78%,  respectively.  The expense assumption is described
below in the "How the Trust is Managed"  and may be amended or  withdrawn at any
time.

EXAMPLE.  The  following  example is  intended  to help you  compare the cost of
investing in the Trust with the cost of investing  in other  mutual  funds.  The
example  assumes  that you  invest  $10,000  in shares of the Trust for the time
periods  indicated and reinvest your  dividends and  distributions.  The example
also assumes that your investment has a 5% return each year and that the Trust's
operating  expenses  remain the same.  Your actual costs may be higher or lower,
because expenses will vary over time.  Based on these  assumptions your expenses
would be as  follows,  whether or not you redeem your  investment  at the end of
each period:


  -----------------------------------------------------------------------------
                                1 year      3 years     5 years    10 years

About the Trust's Investments


THE TRUST'S PRINCIPAL INVESTMENT POLICIES. The Trust invests in short-term money
market  securities  meeting  quality,  maturity  and  diversification  standards
established by its Board of Trustees as well as rules that apply to money market
funds under the Investment Company Act. The Statement of Additional  Information
contains more detailed  information  about the Trust's  investment  policies and
risks.

What  Types of Money  Market  Securities  Does the Trust Invest In? Money market
      instruments are high-quality,  short-term debt instruments.  They may have
      fixed,  variable  or floating  interest  rates.  All of the Trust's  money
      market investments must meet the special quality and maturity requirements
      set under the Investment  Company Act and the special standards set by the
      Board described briefly below. The following is a brief description of the
      types of money market securities the Trust may invest in.

   Municipal  Securities.  The Trust buys municipal bonds and notes,  tax-exempt
      commercial  paper,  certificates of  participation in municipal leases and
      other debt obligations.  These are debt obligations issued by or on behalf
      of the State of  California,  other  states and the  District of Columbia,
      their political  subdivisions (such as cities, towns and counties),  or by
      their agencies, instrumentalities and authorities, if the interest paid on
      the  security  is not  subject  to  federal  individual  income tax in the
      opinion  of  bond  counsel  to the  issuer.  All of  these  types  of debt
      obligations are referred to as "municipal  securities" in this Prospectus.
      All  municipal  securities  in which  the Trust  invests  must  have,  or,
      pursuant to regulations adopted by the Securities and Exchange Commission,
      be deemed to have,  remaining  maturities  of one year or less at the date
      the Trust purchases them.

o     Other Money Market  Obligations.  The balance of the Trust's assets may be
      invested in investments, the income from which may be taxable. The Trust's
      taxable investments include repurchase  agreements,  municipal  securities
      issued to benefit a private user and certain temporary investments.  These
      investments are described below under "Other Investment  Strategies" or in
      the  Statement of  Additional  Information.  Normally,  the Trust will not
      invest more than 20% of its total assets in taxable investments.

      Additionally,  the Trust may buy other money market  instruments  that the
Manager approves under procedures adopted by the Board of Trustees. They must be
U.S.  dollar-denominated  short-term investments that the Manager must determine
to have minimal credit risks.

What  Standards Apply to the Trust's  Investments?  Money market instruments are
      subject to credit  risk,  the risk that the issuer  might not make  timely
      payments of interest on the  security or repay  principal  when it is due.
      The Trust may buy only those  investments  that meet  standards set by the
      Board of  Trustees  and in the  Investment  Company  Act for money  market
      funds. The Trust's Board has adopted evaluation procedures for the Trust's
      portfolio,  and the  Manager has the  responsibility  to  implement  those
      procedures when selecting investments for the Trust.

In  general,  the Trust  buys only  high-quality  investments  that the  Manager
believes  present  minimal  credit risk at the time of purchase.  "High-quality"
investments are:

o rated in one of the two highest  short-term  rating categories of two national
rating organizations, or

o rated by one rating  organization in one of its two highest rating  categories
(if only one rating organization has rated the investment), or

o unrated  investments that the Manager  determines are comparable in quality to
the two highest rating categories.

      The  procedures  also limit the amount of the  Trust's  assets that can be
invested in the  securities of any one issuer  (other than the U.S.  government,
its agencies and  instrumentalities),  to spread the Trust's  investment  risks.
Some of the  Trust's  investment  restrictions  are  more  restrictive  than the
standards  that apply to all money market funds.  For example,  as a fundamental
policy,  the Trust may not invest in any debt  instrument  having a maturity  in
excess  of one year from the date of the  investment.  Finally,  the Trust  must
maintain a dollar-weighted  average portfolio maturity of not more than 90 days,
to reduce interest rate risks.

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

OTHER INVESTMENT STRATEGIES.  To seek its objective,  the Trust can also use the
investment techniques and strategies described below. The Trust might not always
use all of these  techniques and strategies.  These  techniques  involve certain
risks. The Statement of Additional  Information  contains more information about
some of these practices, including limitations on their use that are designed to
reduce some of the risks.

Floating  Rate/Variable  Rate Notes.  The Trust can  purchase  investments  with
      floating or variable  interest  rates.  Variable  rates are  adjustable at
      stated  periodic  intervals.  Floating  rates are  adjusted  automatically
      according to a specified market rate or benchmark,  such as the prime rate
      of a bank.  If the maturity of an  investment is greater than one year, it
      may be purchased only if it has a demand feature. That feature must permit
      the Trust to recover the  principal  amount of the  investment on not more
      than thirty days' notice at any time, or at specified  times not exceeding
      one year from purchase.


"When-Issued"  and  "Delayed-Delivery"  Transactions.  The  Trust  can  purchase
      municipal  securities  on a  "when-issued"  basis and may purchase or sell
      such  securities  on a  "delayed-  delivery"  basis.  These terms refer to
      securities that have been created and for which a market exists, but which
      are not  available for  immediate  delivery.  The Trust does not intend to
      make such purchases for  speculative  purposes.  During the period between
      the  purchase and  settlement,  no payment is made for the security and no
      interest accrues to the buyer from the investment. There is a risk of loss
      to the Trust if the value of the security declines prior to the settlement
      date.


Municipal  Lease  Obligations.  Municipal  leases  are used by state  and  local
      government  authorities  to obtain  funds to acquire  land,  equipment  or
      facilities.  The Trust may invest in  certificates of  participation  that
      represent a proportionate  interest in payments made under municipal lease
      obligations. Some municipal lease obligations have a special risk that the
      municipal  government might not make lease or installment  payments unless
      money is appropriated for that purpose  annually.  If the government stops
      making payments or transfers its payment  obligations to a private entity,
      the  obligation  could  lose  value  or  become  taxable.  Some  of  these
      obligations  might not have an active  trading market and would be subject
      to the fund's limits on "illiquid"  securities  described below. From time
      to time the Trust may invest  more than 5% of its net assets in  municipal
      lease  obligations  that the Manager  has  determined  to be liquid  under
      guidelines set by the Trust's Board of Trustees.

Illiquid and Restricted  Securities.  Investments  may be illiquid  because they
      have no active  trading  market,  making  it  difficult  to value  them or
      dispose of them promptly at an acceptable price. A restricted  security is
      one that  has a  contractual  limit on  resale  or  which  cannot  be sold
      publicly until it is registered  under federal  securities laws. The Trust
      will not invest more than 10% of its net assets in illiquid or  restricted
      securities.  That limit does not apply to  certain  restricted  securities
      that are eligible for resale to qualified  institutional  purchasers.  The
      Manager  monitors  holdings of illiquid  securities on an ongoing basis to
      determine  whether to sell any  holdings to maintain  adequate  liquidity.
      Difficulty  in  selling a  security  may  result in a loss to the Trust or
      additional costs.


Demand Features and Guarantees. The Trust may invest a significant percentage of
   its assets in municipal  securities that have demand features,  guarantees or
   similar  credit and  liquidity  enhancements.  A demand  feature  permits the
   holder of the security to sell the security within a specified period of time
   at a stated  price and  entitles  the  holder of the  security  to receive an
   amount equal to the  approximate  amortized cost of the security plus accrued
   interest.  A guarantee  permits the holder of the  security to receive,  upon
   presentment to the guarantor, the principal amount of the underlying security
   plus  accrued  interest  when  due  or  upon  default.  A  guarantee  is  the
   unconditional  obligation of an entity other than the issuer of the security.
   Demand features and guarantees
      can effectively:
o      shorten the maturity of a variable or floating rate security,
o      enhance the security's credit quality and
o      enhance the ability to sell the security.

      The  aggregate  price for a  security  subject  to a demand  feature  or a
guarantee  may be higher  than the price  that would  otherwise  be paid for the
security  without the guarantee or the demand feature.  When the Trust purchases
securities subject to guarantees or demand features, there is an increase in the
cost of the  underlying  security  and a  corresponding  reduction in its yield.
Because  the Trust  invests in  securities  backed by banks and other  financial
institutions,  changes in the credit quality of these  institutions  could cause
losses to the Trust.  Therefore,  an investment in the Trust may be riskier than
an investment in other types of money market funds.


Repurchase  Agreements.  The Trust may enter into  repurchase  agreements.  In a
      repurchase transaction, the Trust buys a security and simultaneously sells
      it to the vendor for delivery at a future date. Repurchase agreements must
      be fully  collateralized.  However,  if the vendor fails to pay the resale
      price on the delivery  date, the Trust may incur costs in disposing of the
      collateral and may experience  losses if there is any delay in its ability
      to do so. The Trust will not enter into repurchase  transactions that will
      cause more than 10% of the Trust's net assets to be subject to  repurchase
      agreements  having a maturity beyond seven days.  There is no limit on the
      amount  of the  Trust's  net  assets  that may be  subject  to  repurchase
      agreements of 7 days or less. Income earned on repurchase  transactions is
      not tax exempt and accordingly,  under normal market conditions, the Trust
      will limit its investments in repurchase  transactions to 20% of its total
      assets.

Temporary Investments.  In times of unstable or adverse market or economic
      conditions, the Trust can invest up to 100% of its assets in temporary
      defensive investments.  These temporary investments can include:

o obligations  issued or  guaranteed  by the U.S.  government or its agencies or
instrumentalities,

o bankers'  acceptances;  taxable commercial paper rated in the highest category
by a Rating Organization,

o short-term  taxable debt  obligations  rated in one of the two highest  rating
categories  of a Rating  Organization,  o  certificates  of deposit of  domestic
banks, and

o repurchase agreements.


      To the  extent  the  Trust  assumes  a  temporary  defensive  position,  a
significant  portion of the Trust's  distributions may be subject to federal and
California income taxes.

How the Trust is Managed


THE MANAGER.  The  investment  adviser for the Trust is the Manager,  Centennial
Asset Management  Corporation.  The Manager chooses the Trust's  investments and
handles its day-to-day  business.  The Manager carries out its duties subject to
the policies established by the Board of Trustees,  under an Investment Advisory
Agreement  which states the Manager's  responsibilities.  The Agreement sets the
fees paid by the Trust to the Manager and  describes the expenses that the Trust
is responsible to pay to conduct its business.

      The Manager,  a  wholly-owned  subsidiary of  OppenheimerFunds,  Inc., has
operated as an investment  advisor since 1978. As of June 30, 1999,  the Manager
and its affiliates  managed assets of more than $110 billion,  including private
accounts  and  investment  companies  having  more  than 5  million  shareholder
accounts.  The Manager is located at 6803 South Tucson Way, Englewood,  Colorado
80112.

Portfolio Manager. Michael Carbuto is the portfolio manager of the Trust. He is
     the person  principally  responsible  for the day-to-day  management of the
     Trust's portfolio. Mr. Carbuto has had this responsibility since June 1990.
     Mr. Carbuto is a Vice President of the Manager and  OppenheimerFunds,  Inc.
     and is an  officer  and  portfolio  manager  of other  funds  for which the
     Manager serves as investment adviser.

Advisory Fees.  Under the  Investment  Advisory  Agreement,  the Trust  pays the
     Manager an  advisory  fee at an annual  rate that  declines  on  additional
     assets as the Trust grows.  That fee is computed on the average  annual net
     assets of the Trust as of the close of each  business day. The annual rates
     are: 0.500% of the first $250 million of the Trust's net assets;  0.475% of
     the next $250 million;  0.450% of the next $250 million; 0.425% of the next
     $250 million and; 0.400% of net assets in excess of $1 billion. The Manager
     has  voluntarily  undertaken  to assume  any  expenses  of the Trust in any
     fiscal year they exceed 0.80% of the Trust's average annual net assets. The
     Manager reserves the right to amend or terminate that expense assumption at
     any time.  The  Trust's  management  fee for its fiscal year ended June 30,
     1999 was 0.50% of the Trust's average annual net assets.

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

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

How to Buy Shares


HOW ARE SHARE PRICES DETERMINED?  Shares of the Trust are sold at their offering
price,  which is the net asset value per share without any sales charge. The net
asset value per share will  normally  remain fixed at $1.00 per share.  However,
there is no guarantee that the Trust will be able to maintain a stable net asset
value of $1.00 per share.

      The offering  price that applies to a purchase  order is based on the next
calculation   of  the  net  asset  value  per  share  that  is  made  after  the
Sub-Distributor  (OppenheimerFunds  Distributor, Inc. is the Sub-Distributor for
the Trust)  receives the purchase order at its offices in Denver,  Colorado,  or
after any agent appointed by the Sub-Distributor receives the order and sends it
to the Sub-Distributor as described below.

How   is the Trust's Net Asset Value  Determined?  The net asset value of shares
      of the Trust is determined twice each day, at 12:00 Noon and at 4:00 P.M.,
      on each day The New York Stock  Exchange is open for trading  (referred to
      in this Prospectus as a "regular business day"). All references to time in
      this Prospectus mean "New York time."

      The net asset value per share is  determined  by dividing the value of the
Trust's net assets by the number of shares that are outstanding.  Under a policy
adopted by the Board of Trustees,  the Trust uses the  amortized  cost method to
value its securities to determine net asset value.

      The shares of the Trust offered by this  Prospectus  are  considered to be
Class A shares for the purposes of exchanging them or reinvesting  distributions
among other eligible funds that offer more than one class of shares.

IS THERE A MINIMUM INVESTMENT?  There is a minimum initial investment  described
below depending on how you buy and pay for your shares.  You can make additional
investments  at  any  time  with  as  little  as  $25.  The  minimum  investment
requirements do not apply to reinvesting  distributions  from the Trust or other
eligible  funds  (a  list  of  them  appears  in  the  Statement  of  Additional
Information,  or you  can ask  your  dealer  or  call  the  Transfer  Agent)  or
reinvesting   distributions   from  unit   investment   trusts  that  have  made
arrangements  with the  Distributor.  . HOW ARE  SHARES  PURCHASED?  You can buy
shares in one of several ways:

BuyingShares Through a Dealer's Automatic Purchase and Redemption  Program.  You
      can buy  shares of the  Trust  through  a  broker-dealer  that has a sales
      agreement  with the  Trust's  Sub-Distributor  that  allows  shares  to be
      purchased through the dealer's Automatic Purchase and Redemption  Program.
      Shares of the Trust are sold mainly to customers of participating  dealers
      that offer the Trust's shares under these special  purchase  programs.  If
      you   participate  in  an  Automatic   Purchase  and  Redemption   Program
      established by your dealer,  your dealer buys shares of the Trust for your
      account  with  the  dealer.  Program  participants  should  also  read the
      description of the program provided by their dealer.

BuyingShares  Through Your  Dealer.  If you do not  participate  in an Automatic
      Purchase and Redemption  Program,  you may buy shares of the Trust through
      any  broker-dealer  that has a sales  agreement with the  Sub-Distributor.
      Your dealer will place your order with the Sub-Distributor on your behalf.

BuyingShares Directly Through the Sub-Distributor.  You can also purchase shares
      directly  through the  Sub-Distributor.  Shareholders  who make  purchases
      directly  and hold  shares in their own names are  referred  to as "direct
      shareholders" in this Prospectus.

      The  Sub-Distributor  may appoint servicing agents to accept purchase (and
redemption) orders,  including  broker-dealers  that have established  Automatic
Purchase and Redemption Programs.  The Sub-Distributor,  in its sole discretion,
may reject any purchase order for shares of the Trust.

AUTOMATIC  PURCHASE  AND  REDEMPTION  PROGRAMS?  If you buy  shares of the Trust
through your  broker-dealer's  Automatic Purchase and Redemption  Program,  your
broker-dealer  will buy your shares for your Program  Account and will hold your
shares in your  broker-dealer's  name.  These  purchases  will be made under the
procedures  described in "Guaranteed Payment" below. Your Automatic Purchase and
Redemption Program Account may have minimum investment requirements  established
by your  broker-dealer.  You should  direct all questions  about your  Automatic
Purchase  and  Redemption  Program to your  broker-dealer,  because  the Trust's
transfer agent does not have access to information about your account under that
Program.

Guaranteed Payment  Procedures.  Some  broker-dealers may have arrangements with
      the  Sub-Distributor to enable them to place purchase orders for shares of
      the Trust and to guarantee  that the Trust's  custodian  bank will receive
      Federal   Funds  to  pay  for  the  shares  prior  to   specified   times.
      Broker-dealers   whose  clients  participate  in  Automatic  Purchase  and
      Redemption Programs may use these guaranteed payment procedures to pay for
      purchases of shares of the Trust.

   If the  Distributor  receives a purchase order before 12:00 Noon on a regular
      business day with the broker-dealer's guarantee that the Trust's custodian
      bank will receive  payment for those shares in Federal  Funds by 2:00 P.M.
      on that  same day,  the  order  will be  effected  at the net asset  value
      determined at 12:00 Noon that day.  Distributions  will begin to accrue on
      the shares on that day if the Federal  Funds are  received by the required
      time.

   If the  Distributor  receives a purchase  order after 12:00 Noon on a regular
      business day with the broker-dealer's guarantee that the Trust's custodian
      bank will receive  payment for those shares in Federal  Funds by 2:00 P.M.
      on that  same day,  the  order  will be  effected  at the net asset  value
      determined  at 4:00 P.M. that day.  Distributions  will begin to accrue on
      the shares on that day if the Federal  Funds are  received by the required
      time.


   If the Distributor receives a purchase order between 12:00 Noon and 4:00 P.M.
      on a regular  business  day with the  broker-dealer's  guarantee  that the
      Trust's  custodian  bank will receive  payment for those shares in Federal
      Funds by 4:00 P.M.  the next  regular  business  day,  the  order  will be
      effected  at the net asset  value  determined  at 4:00 P.M. on the day the
      order is  received  and  distributions  will begin to accrue on the shares
      purchased  on the next  regular  business  day if the  Federal  Funds  are
      received by the required time.


HOW CAN DIRECT  SHAREHOLDERS BUY SHARES?  Direct  shareholders may buy shares of
the Trust by  completing a Centennial  Funds New Account  Application  (enclosed
with this  Prospectus) and sending it to the  Sub-Distributor,  OppenheimerFunds
Distributor,  Inc., P.O. Box 5143, Denver,  Colorado 80217. Payment must be made
by check or by Federal Funds wire as described below. If you don't list a dealer
on the application,  OppenheimerFunds  Distributor,  Inc., the  Sub-Distributor,
will act as your agent in buying the  shares.  However,  we  recommend  that you
discuss your investment  with a financial  advisor before you make a purchase to
be sure that the Trust is appropriate for you.

      The Trust  intends to be as fully  invested as  possible  to maximize  its
yield.   Therefore,   newly-purchased  shares  normally  will  begin  to  accrue
distributions  after the  Sub-Distributor  or its agent  accepts  your  purchase
order,  starting on the business day after the Trust receives Federal Funds from
the purchase payment.

Payment by Check.  Direct  shareholders  may pay for  purchases of shares of the
      Trust by check. Send your check, payable to "OppenheimerFunds Distributor,
      Inc.,"  along with your  Application  to the  address  listed  above.  For
      initial purchases,  your check should be payable in U.S. dollars and drawn
      on a U.S.  bank so that  distributions  will  begin to  accrue on the next
      regular business day after the Distributor accepts your purchase order. If
      your check is not drawn on a U.S. bank and is not payable in U.S. dollars,
      the shares will not be purchased  until the Distributor is able to convert
      the purchase  payment to Federal Funds.  In that case  distributions  will
      begin to accrue on the purchased  shares on the next regular  business day
      after the  purchase is made.  The minimum  initial  investment  for direct
      shareholders by check is $500.

Payment by Federal  Funds Wire.  Direct  shareholders  may pay for  purchases of
      shares of the Trust by Federal  Funds  wire.  You must also  forward  your
      Application to the Sub-Distributor's  address listed above. Before sending
      a wire,  call the  Sub-Distributor's  Wire  Department  at  1-800-525-9310
      (toll-free from within the U.S.) or  303-768-3200  (from outside the U.S.)
      to  notify  the  Sub-Distributor  of  the  wire,  and to  receive  further
      instructions.

      Distributions will begin to accrue on the purchased shares on the purchase
date that is a regular  business day if the Federal Funds from your wire and the
Application are received by the  Sub-Distributor  and accepted by 12:00 Noon. If
the  Distributor  receives  the  Federal  Funds from your wire and  accepts  the
purchase   order  between  12:00  Noon  and  4:00  P.M  on  the  purchase  date,
distributions  will begin to accrue on the shares on the next  regular  business
day. The minimum investment by Federal Funds Wire is $2,500.

Buying Shares Through Automatic Investment Plans. Direct shareholders can
     purchase  shares of the Trust  automatically  each month by authorizing the
     Trust's  Transfer  Agent to debit your account at a U.S.  domestic  bank or
     other financial  institution.  Details are in the Automatic Investment Plan
     Application  and the  Statement  of  Additional  Information.  The  minimum
     monthly purchase is $25.

Service (12b-1)  Plans.  The Trust has adopted a service plan. It reimburses the
      Distributor  for a portion of its costs incurred for services  provided to
      accounts that hold shares of the Trust. Reimbursement is made quarterly at
      an annual  rate of up to 0.20% of the  average  annual  net  assets of the
      Trust.  The  Distributor  currently uses all of those fees to pay dealers,
      brokers,  banks and other financial  institutions  quarterly for providing
      personal services and maintenance of accounts of their customers that hold
      shares of the Trust.


How to Sell Shares


You can sell  (redeem)  some or all of your shares on any regular  business day.
Your shares will be sold at the next net asset value calculated after your order
is received in proper form (which means that it must comply with the  procedures
described below) and is accepted by the Transfer Agent.


HOW CAN PROGRAM  PARTICIPANTS  SELL SHARES?  If you  participate in an Automatic
Purchase and Redemption Program sponsored by your broker-dealer, you must redeem
shares held in your Program  Account by contacting your  broker-dealer  firm, or
you can  redeem  shares by writing  checks as  described  below.  You should not
contact the Trust or its Transfer  Agent  directly to redeem shares held in your
Program Account.  You may also arrange (but only through your  broker-dealer) to
have the  proceeds  of redeemed  Trust  shares  sent by Federal  Funds wire,  as
described below in "Sending Redemption Proceeds by Wire."


HOW CAN DIRECT SHAREHOLDERS REDEEM SHARES?  Direct shareholders can redeem their
shares by writing a letter to the Transfer Agent, Shareholder Services, Inc., by
using checkwriting  privileges,  or by telephone.  You can also set up Automatic
Withdrawal  Plans to redeem  shares on a regular  basis.  If you have  questions
about any of these  procedures,  and especially if you are redeeming shares in a
special  situation,  such as due to the death of the owner or from a  retirement
plan  account,   please  call  the  Transfer  Agent  for  assistance  first,  at
1-800-525-9310.

Certain Requests  Require a  Signature  Guarantee.  To protect you and the Trust
      from fraud,  the  following  redemption  requests  for  accounts of direct
      shareholders  must be in writing and must  include a  signature  guarantee
      (although  there may be other  situations  that also  require a  signature
      guarantee):
   o  You wish to redeem $100,000 or more and receive a check

   o  The  redemption  check is not payable to all  shareholders  listed on the
      account statement

   o  The redemption check is not sent to the address of record on your account
      statement
   o Shares are being transferred to an account with a different owner or name o
   Shares are being redeemed by someone (such as an Executor) other than the

      owners listed in the account registration

Where Can Direct  Shareholders  Have Their Signatures  Guaranteed?  The Transfer
      Agent will accept a guarantee  of your  signature by a number of financial
      institutions, including:

o      a U.S. bank, trust company, credit union or savings association,
o      a foreign bank that has a U.S. correspondent bank,
o      a U.S. registered dealer or broker in securities, municipal securities or

      government securities, or

o    a U.S. national securities exchange, a registered securities  association
     or a clearing agency.

      If you are  signing  on  behalf  of a  corporation,  partnership  or other
business or as a fiduciary, you must also include your title in the signature.


How Can Direct Shareholders Sell Shares by Mail?  Write a letter to the Transfer
      Agent that includes:

   o  Your name
   o  The Trust's name
   o Your account  number (from your account  statement) o The dollar  amount or
   number of shares to be  redeemed o Any  special  payment  instructions  o Any
   share certificates for the shares you are selling

   o  The signatures of all registered owners exactly as listed in the account
      statement, and
   o  Any special  documents  requested by the Transfer  Agent to assure  proper
      authorization  of the person  asking to sell the  shares  (such as Letters
      Testamentary of an Executor).

How   Can Direct Shareholders Sell Shares by Telephone?  Direct shareholders and
      their dealer  representative  of record may also sell shares by telephone.
      To enable you to receive the redemption  price on a regular  business day,
      the Transfer  Agent must receive the request by 4:00 P.M. on that day. You
      may not redeem  shares held under a share  certificate  or in a retirement
      account by telephone.  To redeem shares through a service  representative,
      call 1-800-525-9310.  The check for proceeds of telephone redemptions will
      be payable to the shareholder(s) of record and will be sent to the address
      of record for the account.  Up to $100,000 may be redeemed by telephone in
      any 7-day period.  Telephone  redemptions are not available within 30 days
      of changing the address on an account.

Sending Redemption  Proceeds By Wire.  While the Transfer  Agent  normally sends
      direct  shareholders  their  money by check,  you can  arrange to have the
      proceeds  of the  shares  you sell sent by  Federal  Funds  wire to a bank
      account you  designate.  It must be a commercial  bank that is a member of
      the Federal Reserve wire system.  The minimum redemption you can have sent
      by wire is $2,500.  There is a $10 fee for each  wire.  To find out how to
      set  up  this  feature  on  an  account  or  to  arrange  a  wire,  direct
      shareholders should call the Transfer Agent at 1-800-525-9310. If you hold
      your shares  through  your  dealer's  Automatic  Purchase  and  Redemption
      Program, you must contact your dealer to arrange a Federal Funds wire.

Can   Direct  Shareholders  Submit Requests by Fax? Direct shareholders may send
      requests for certain types of account  transactions  to the Transfer Agent
      by fax  (telecopier).  Please call  1-800-525-9310  for information  about
      which transactions may be handled this way. Transaction requests submitted
      by fax are  subject to the same  rules and  restrictions  as  written  and
      telephone requests described in this Prospectus.

HOW DO I WRITE CHECKS  AGAINST MY ACCOUNT?  Automatic  Purchase  and  Redemption
Program  participants  may write  checks  against  an account  held under  their
Program,  but must arrange for  checkwriting  privileges  through their dealers.
Direct  shareholders  may write checks against their account by requesting  that
privilege on the account  Application  or by contacting  the Transfer  Agent for
signature cards. They must be signed (with a signature  guarantee) by all owners
of the account and returned to the Transfer  Agent so that checks can be sent to
you to use. Shareholders with joint accounts can elect in writing to have checks
paid over the signature of one owner.


   o  Checks can be written to the order of  whomever  you wish,  but may not be
      cashed at the bank the checks are payable through or the Trust's custodian
      bank
   o  Checkwriting privileges are not available for accounts holding shares that
      are subject to a contingent deferred sales charge.
   o  Checks must be written for at least $250.

   o Checks cannot be paid if they are written for more than your account value.
   o You may not write a check that would require the redemption of shares that

      were purchased by check or Automatic  Investment  Plan payments within the
      prior 10 days.
   o  Don't use your  checks  if you  changed  your  account  number,  until you
      receive new checks.


WILL I PAY A SALES CHARGE WHEN I SELL MY SHARES? The Trust does not charge a fee
to redeem shares that were bought directly or by reinvesting  distributions from
the Trust or another Centennial Trust or eligible fund.  Generally,  there is no
fee to redeem  shares  of the Trust  bought  by  exchange  of shares of  another
Centennial Trust or eligible fund. However,

   if you acquired  shares of the Trust by exchanging  Class A shares of another
      eligible fund that you bought  subject to the Class A contingent  deferred
      sales charge, and

   those shares  are still  subject  to the Class A  contingent  deferred  sales
      charge when you exchange them into the Trust, then
   youwill pay the  contingent  deferred sales charge if you redeem those shares
      from the Trust within 18 months of the purchase  date of the shares of the
      fund you exchanged.

How to Exchange Shares


Shares of the Trust can be  exchanged  for  shares of certain  other  Centennial
Trusts or other eligible funds, depending on whether you own your shares through
your  dealer's  Automatic  Purchase  and  Redemption  Program  or  as  a  direct
shareholder.

HOW CAN PROGRAM PARTICIPANTS EXCHANGE SHARES? If you participate in an Automatic
Purchase  and  Redemption  Program  sponsored  by  your  broker-dealer,  you may
exchange  shares held in your  Program  Account for shares of  Centennial  Money
Market  Trust,   Centennial  Government  Trust,  Centennial  Tax  Exempt  Trust,
Centennial  California Tax Exempt Trust and Centennial New York Tax Exempt Trust
(referred to in this  Prospectus as the "Centennial  Trusts"),  if available for
sale in your state of residence, by contacting your broker- dealer and obtaining
a Prospectus of the selected Centennial Trust.

HOW CAN DIRECT  SHAREHOLDERS  EXCHANGE SHARES?  Direct shareholders can exchange
shares of the Trust for Class A shares of certain  eligible  funds listed in the
Statement of Additional  Information.  To exchange shares, you must meet several
conditions:


   o  Shares of the fund  selected  for exchange  must be available  for sale in
      your state of residence.
   o  The  prospectuses  of the Trust and the fund whose  shares you want to buy
      must offer the exchange privilege.
   o  You must hold the shares you buy when you  establish  your  account for at
      least 7 days  before you can  exchange  them.  After the account is open 7
      days, you can exchange shares every regular business day.
   o  You must meet the minimum purchase  requirements for the fund you purchase
      by exchange.

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

      Shares of a particular class of an eligible fund may be exchanged only for
shares of the same class in other eligible funds. For example,  you can exchange
shares  of the  Trust  only for  Class A shares  of  another  fund,  and you can
exchange only Class A shares of another eligible fund for shares of the Trust.

      You may pay a sales charge when you exchange shares of the Trust.  Because
shares of the Trust are sold without sales  charge,  in some cases you may pay a
sales charge when you exchange  shares of the Trust for shares of other eligible
funds that are sold subject to a sales  charge.  You will not pay a sales charge
when you exchange  shares of the Trust  purchased by  reinvesting  distributions
from the Trust or other eligible funds (except  Oppenheimer  Cash Reserves),  or
when you  exchange  shares of the Trust  purchased  by  exchange of shares of an
eligible fund on which you paid a sales charge.


      For tax purposes,  exchanges of shares involve a sale of the shares of the
fund you own and a purchase of the shares of the other fund, which may result in
a capital gain or loss. Since shares of the Trust normally  maintain a $1.00 net
asset  value,  in most cases you should not realize a capital  gain or loss when
you sell or exchange your shares.


      Direct  shareholders can find a list of eligible funds currently available
for exchanges in the Statement of Additional  Information  or you can obtain one
by calling a service  representative  at  1-800-525-9310.  The list of  eligible
funds can change from time to time.

How Do Direct Shareholders Submit Exchange Requests?  Direct shareholders may
      request exchanges in writing or by telephone:

   o  Written Exchange Requests. Complete an Exchange Authorization Form, signed
      by all owners of the account. Send it to the Transfer Agent at the address
      on the back cover.


   o  Telephone  Exchange  Requests.  Telephone exchange requests may be made by
      calling a service  representative at 1-800-525-9310.  Telephone  exchanges
      may be made  only  between  accounts  that  are  registered  with the same
      name(s) and address.  Shares held under  certificates may not be exchanged
      by telephone.

ARE THERE  LIMITATIONS  ON EXCHANGES?  There are certain  exchange  policies you
should be aware of:

  o  Shares are normally  redeemed from one fund and purchased  from the other
     fund in the exchange  transaction on the same regular business day on which
     the  Transfer  Agent  receives an  exchange  request  that  conforms to the
     policies  described above.  Requests for exchanges to any of the Centennial
     Trusts  must be received  by the  Transfer  Agent by 4:00 P.M. on a regular
     business  day to be effected  that day.  The  Transfer  Agent must  receive
     requests to exchange shares of the Trust to funds other than the Centennial
     Trusts  on a  regular  business  day by the  close  of The New  York  Stock
     Exchange  that day.  The close is normally  4:00 P.M. but may be earlier on
     some days.

   o  Either  fund  may  delay  the  purchase  of  shares  of the  fund  you are
      exchanging   into  up  to  seven  days  if  it   determines  it  would  be
      disadvantaged  by a same-day  exchange.  For  example,  the receipt of the
      multiple  exchange  requests from a "market timer" might require a fund to
      sell securities at a disadvantageous time and/or price.


   o  Because excessive trading can hurt fund performance and harm shareholders,
      the Trust  reserves the right to refuse any exchange  request that may, in
      the  opinion  of the  Trust,  be  disadvantageous,  or to refuse  multiple
      exchange requests submitted by a shareholder or dealer.

   o  The Trust may amend,  suspend or terminate  the exchange  privilege at any
      time.  The Trust will provide you notice  whenever it is required to do so
      by  applicable  law,  but it may  impose  these  changes  at any  time for
      emergency purposes.


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

Shareholder Account Rules and Policies

More information  about the Trust's policies and procedures for buying,  selling
and exchanging shares is contained in the Statement of Additional Information.


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


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


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


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

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

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


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

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


To    avoid sending duplicate copies of materials to households,  the Trust will
      mail only one copy of each annual and  semi-annual  report to shareholders
      having the same last name and  address on the  Trust's  records.  However,
      each shareholder may call the Transfer Agent at 1-800-525-9310 to ask that
      copies of those materials be sent personally to that shareholder.

Dividends and Tax Information

DIVIDENDS.  The Trust intends to declare  dividends from net  investment  income
each regular business day and to pay those dividends to shareholders monthly. To
maintain  a net  asset  value of $1.00  per  share,  the  Trust  might  withhold
dividends or make  distributions  from capital or capital gains. Daily dividends
will not be declared or paid on newly  purchased  shares until Federal Funds are
available to the Trust from the purchase payment for such shares.


CAPITAL GAINS. The Trust normally holds its securities to maturity and therefore
will not usually pay capital  gains.  Although  the Trust does not seek  capital
gains,  the  Trust  could  realize  capital  gains on the sale of its  portfolio
securities.  If it does, it may make  distributions out of any net short-term or
long-term   capital  gains  in  December  of  each  year.  The  Trust  may  make
supplemental  distributions  of dividends and capital gains following the end of
its fiscal year.

What  Choices Do I Have for Receiving Distributions?  For Automatic Purchase and
      Redemption   Programs,   dividends  and  distributions  are  automatically
      reinvested  in  additional  shares  of  the  selected  Trust.  For  direct
      shareholders,  when you open your  account,  you  should  specify  on your
      application how you want to receive your dividends and distributions.  You
      have four options:

     o Reinvest All  Distributions  in the Trust.  You can elect to reinvest all
     dividends  and capital  gains  distributions  in  additional  shares of the
     Trust.

     o Reinvest  Capital  Gains Only.  You can elect to reinvest  capital  gains
     distributions  in the Trust while  receiving  dividends  by check or having
     them sent to your bank account.

     o Receive All  Distributions  in Cash. You can elect to receive a check for
     all  dividends and capital  gains  distributions  or have them sent to your
     bank.

     o Reinvest  Your  Distributions  in Another  Account.  You can reinvest all
     distributions  in the same class of shares of another eligible fund account
     you have established.

Under  the  terms  of  Automatic   Purchase  and   Redemption   Programs,   your
broker-dealer  can  redeem  shares to  satisfy  debit  balances  arising in your
Program  Account.  If that  occurs,  you will be entitled to  dividends on those
shares as described in your Program Agreements.

TAXES.  Exempt interest  dividends paid from net investment income earned by the
Trust on municipal  securities  will be excludable from gross income for federal
income tax purposes.  A portion of a dividend that is derived from interest paid
on certain "private  activity bonds" may be an item of tax preference if you are
subject to the  alternative  minimum tax. If the Trust earns interest on taxable
investments,  any  dividends  derived  from  those  earnings  will be taxable as
ordinary income to shareholders.


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

      Dividends and capital gains distributions may be subject to state or local
taxes.  Long-term  capital  gains are taxable as  long-term  capital  gains when
distributed to shareholders,  and may be taxable at different rates depending on
how long the Trust  holds the  asset.  It does not matter how long you have held
your  shares.  Dividends  paid from  short-term  capital  gains are  taxable  as
ordinary income. Whether you reinvest your distributions in additional shares or
take them in cash, the tax treatment is the same. Every year the Trust will send
you and the IRS a statement  showing the amount of any taxable  distribution you
received in the previous year as well as the amount of your tax-exempt income.


Remember,  There  May be Taxes  on  Transactions.  Because  the  Trust  seeks to
      maintain a stable $1.00 per share net asset value, it is unlikely that you
      will have a capital gain or loss when you sell or exchange your shares.  A
      capital gain or loss is the difference  between the price you paid for the
      shares and the price you received when you sold them.  Any capital gain is
      subject to capital gains tax.


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


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

       Additional Information About the Trust's Investment Policies and Risks

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


The Trust's  Investment  Policies.  The composition of the Trust's portfolio and
the  techniques  and  strategies  that the  Trust's  Manager  uses in  selecting
portfolio  securities  will vary over time. The Trust is not required to use all
of the  investment  techniques and  strategies  described  below at all times in
seeking  its goal.  It may use some of the  special  investment  techniques  and
strategies at some times or not at all.

      The Trust will not make  investments with the objective of seeking capital
growth.  However,  the value of the securities held by the Trust 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  increase  after a security is purchased,  that  security  would
normally  decline in value.  Conversely,  if  interest  rates  decrease  after a
security is purchased,  its value would rise.  However,  those  fluctuations  in
value will not generally  result in realized  gains or losses to the Trust since
the Trust  does not  usually  intend to  dispose  of  securities  prior to their
maturity.  A debt  security held to maturity is redeemable by its issuer at full
principal value plus accrued interest.


      The Trust may sell securities prior to their maturity,  to attempt to take
advantage  of  short-term  market  variations,  or because  of a revised  credit
evaluation  of the issuer or other  considerations.  The Trust may also do so to
generate cash to satisfy  redemptions of Trust shares.  In such cases, the Trust
may realize a capital gain or loss on the security.

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

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

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

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

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

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

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

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

        |_| Private Activity  Municipal  Securities.  The Tax Reform Act of 1986
(the "Tax Reform Act") reorganized,  as well as amended, the rules governing tax
exemption for interest on certain types of municipal securities.  The Tax Reform
Act  generally  did not change  the tax  treatment  of bonds  issued in order to
finance  governmental  operations.  Thus,  interest on general  obligation bonds
issued by or on behalf of state or local governments,  the proceeds of which are
used to finance the operations of such governments,  continues to be tax-exempt.
However,   the  Tax  Reform  Act  limited  the  use  of  tax-exempt   bonds  for
non-governmental  (private) purposes. More stringent restrictions were placed on
the use of proceeds of such bonds. Interest on certain private activity bonds is
taxable  under  the  revised  rules.  There  is  an  exception  for  "qualified"
tax-exempt private activity bonds, for example,  exempt facility bonds including
certain  industrial  development  bonds,  qualified  mortgage  bonds,  qualified
Section 501(c)(3) bonds, and qualified student loan bonds.  Normally,  the Trust
will not invest more than 20% of its total assets in private activity  municipal
securities or other taxable investments.

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

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

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

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

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

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

      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 Trust 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 Trust'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 Trust would be limited as  described  below in  "Illiquid
Securities."  From  time to time the Trust  may  invest  more than 5% of its net
assets in municipal  lease  obligations  that the Manager has  determined  to be
liquid under guidelines set by the Board of Trustees.  Those guidelines  require
the Manager to evaluate:
      |_| the frequency of trades and price quotations for such securities;

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

     |_| the availability of market-makers; and

     |_| the nature of the trades for such securities.

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

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

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

Ratings of Securities - Portfolio Quality and  Diversification.  Under Rule 2a-7
of the Investment Company Act, the Trust uses the amortized cost method to value
its  portfolio  securities  to determine  the Trust's net asset value per share.
Rule 2a-7 imposes requirements for the maturity,  quality and diversification of
the  securities  which  the  Trust  buys.  The Trust  may  purchase  only  those
securities that the Manager, under procedures approved by the Board of Trustees,
has determined have minimal credit risk and, as such, are "eligible securities".

      |_| Quality.  Eligible  securities  are  securities  that have  received a
rating  in one of the two  highest  short-term  rating  categories  by a  rating
organization.   Rating   organizations  are  designated  by  the  SEC.  Eligible
securities  may  be  "first  tier"  or  "second  tier"  securities.  First  tier
securities  are those that have  received a rating in the highest  category  for
short term debt  obligations by at least two rating  organizations.  If only one
rating  organization  has rated the  security,  it must be rated in the  highest
category for that rating organization. U.S. government securities and securities
issued by a registered money market mutual fund are also first tier securities.


      The Trust may also buy second tier "conduit  securities".  These  eligible
securities are securities rated by rating  organizations  but are not first tier
securities.  Conduit  securities  are  municipal  securities  such as industrial
development  or revenue  bonds issued to finance  non-government  projects.  The
payment  of the  principal  and  interest  on a  conduit  security  is  not  the
obligation of the municipal issuer,  but is the obligation of another person who
is ultimately responsible for the payment of principal and interest, such as the
user of the facility.  The Trust may not invest more than 5% of its total assets
in second tier conduit securities.


      The Trust may also buy unrated  securities that the Manager determines are
comparable  in quality to a first or second tier  security  by applying  certain
criteria  established  by the board to  determine  its  creditworthiness.  These
criteria require a high quality short term or long-term rating (depending on the
security)  from a rating  organization.  Unrated  securities  the  Trust may buy
include asset backed  securities and securities  subject to "demand features" or
"guarantees".

      The Trust may purchase a security  subject to a guarantee if the guarantee
is an eligible security or a first tier security.  The trust may also purchase a
security  subject to a "conditional"  demand feature if the demand feature is an
eligible  security  and the  Manager  has decided  that the  conditional  demand
feature meets the requirements imposed by Rule 2a-7.


      If a  security's  rating is  downgraded,  the Manager  and/or the Board of
Trustees may have to reassess  the  security's  credit  risk.  If a security has
ceased to be a First Tier Security,  the Manager will promptly  reassess whether
the security  continues to present  minimal credit risk. If the Manager  becomes
aware that any Rating  Organization  has  downgraded its rating of a Second Tier
Security or rated an unrated  security below its second highest rating category,
the Trust's  Board of Trustees  shall  promptly  reassess  whether the  security
presents  minimal  credit  risk and whether it is in the best  interests  of the
Trust to dispose of it. If the Trust  disposes of the security  within five days
of the Manager learning of the downgrade,  the Manager will provide the Board of
Trustees with subsequent notice of such downgrade.  If a security is in default,
or ceases to be an  Eligible  Security,  or is  determined  no longer to present
minimal credit risks,  the Board of Trustees must determine  whether it would be
in the best interests of the Trust to dispose of the security.




      |_|  Diversification.  With respect to 75% of its total assets,  the Trust
cannot  invest  more than 5% of its total  assets  in  securities  issued by one
issuer.  It cannot  invest more than 5% of its total assets in securities of one
issuer  unless the  security  is a first tier  security.  The Trust also  cannot
invest more than 1% of its total assets or $1.0  million,  whichever is greater,
in second tier securities of one issuer. For diversification purposes, the Trust
is considered to have purchased the security  underlying a repurchase  agreement
if the repurchase  agreement is fully  collateralized.  For a refunded security,
the Trust is considered to have the U.S.  government  securities  underlying the
refunded security. For conduit securities,  the Trust considers the issuer to be
the person  ultimately  responsible for payment of the obligation.  If the Trust
buys an asset  backed  security,  the issuer of the security is deemed to be the
"special purpose" entity which issued the security.  A special purpose entity is
an entity  which is  organized  solely for the purpose of issuing  asset  backed
securities.  If the asset backed securities issued by the special purpose entity
include the  obligations of another person or another special purpose entity and
those obligations amount to 10% or more of the asset backed securities the Trust
buys,  that other person or entity is  considered to be the issuer of a pro rata
percentage of the asset backed security.


      The Trust may buy a security subject to a demand feature or guarantee.  In
this case,  with  respect to 75% of its total  assets,  the Trust may not invest
more than 10% of its total assets in  securities  issued by or subject to demand
features  or  guarantees  issued by the same  issuer.  If the demand  feature or
guarantee  is a second tier  security,  the Trust may not invest more than 5% of
its total assets in securities subject to demand features or guarantees from the
same issuer.  And, the Trust may not invest more than 10% of its total assets in
securities  issued by or subject to demand  features or guarantees from the same
issuer. However, if the demand feature or guarantee is issued by a person who is
a non-controlled  person, the Trust does not have to limit its investments to no
more than 10% of its total assets in  securities  issued by or subject to demand
features or guarantees from the same issuer.

      |_| Maturity. The Trust must maintain a dollar-weighted  average portfolio
maturity of not more than 90 days, and the maturity of any single  security must
not be in  excess  of one year  from the date of the  investment.  This one year
limit is more restrictive than the maturity limitation imposed by Rule 2a-7. The
Trust  also  may  buy  adjustable  and  floating  rate  securities,  enter  into
repurchase agreements and lend portfolio  securities.  Rule 2a-7 defines how the
maturities  of  these  securities  are  determined.  The  Trust  may  buy  these
securities  if their  maturities  do not  exceed  one year  from the date of the
investment.

      |_| Demand  Features and  Guarantees.  Demand  features and guarantees and
some of their uses are described in the  Prospectus.  The Trust also uses demand
features and  guarantees to satisfy the maturity,  quality and  diversifications
requirements  described  above.  The Trust considers the person which issues the
demand  feature  as the  person to whom the  Trust  will  look for  payment.  An
unconditional  demand  feature is  considered a guarantee and the Trust looks to
the person making the guarantee for payment of the  obligation of the underlying
security.

      When the Trust buys municipal  securities,  it may obtain a demand feature
from the seller to repurchase the securities  that entitles the Trust to achieve
same day settlement  from the repurchaser and to receive an exercise price equal
to the amortized cost of the underlying security plus accrued interest,  if any,
at the time of exercise. Another type of demand feature purchased in conjunction
with a  Municipal  Security  enables the Trust to sell the  underlying  security
within a specified  period of time at a fixed exercise price.  The Trust may pay
for demand  features  either  separately in cash or by paying a higher price for
the securities  acquired  subject to the demand  features.  The Trust will enter
into these  transactions  only with banks and dealers  which,  in the  Manager's
opinion,  present minimal credit risks. The Trust's purchases of demand features
are  subject to the  provisions  of Rule 2a-7 under the  Investment  Company Act
because  the  Trust  uses the  amortized  cost  method  to value  its  portfolio
securities.

      The Trust's  ability to exercise a demand feature or guarantee will depend
on the  ability  of the bank or dealer to pay for the  securities  if the demand
feature or guarantee is exercised.  If the bank or dealer should  default on its
obligation,  the Trust might not be able to recover all or a portion of any loss
sustained  from  having to sell the  security  elsewhere.  Demand  features  and
guarantees are not  transferable  by the Trust,  and therefore  terminate if the
Trust sells the underlying security to a third party. The Trust intends to enter
into  these  arrangements  to  facilitate  portfolio  liquidity,  although  such
arrangements  may enable the Trust to sell a security  at a  pre-arranged  price
which may be higher  than the  prevailing  market  price at the time the  demand
feature or guarantee is exercised.  Any considerations paid by the Trust for the
demand feature  (which  increases the cost of the security and reduces the yield
otherwise  available for the security) will be reflected on the Trust's books as
unrealized  depreciation  while the demand  feature or guarantee is held,  and a
realized gain or loss when demand feature is exercised or expires.


Other Investment Strategies

Floating Rate/Variable Rate Obligations.  Floating rate and variable rate demand
notes are tax-exempt  obligations  which may have a stated maturity in excess of
one year,  but may  include  features  that  permit the  holder to  recover  the
principal amount of the underlying security at specified intervals not exceeding
one year on not more than thirty  days'  notice at any time.  The issuer of such
notes normally has a corresponding right, after a given period, to prepay in its
discretion the outstanding  principal  amount of the note plus accrued  interest
upon a specified  number of days notice to the holder.  The  interest  rate on a
floating  rate  demand note is based on a stated  prevailing  market rate 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 no more than one year.
Generally,  the  changes  in the  interest  rate on such  securities  reduce the
fluctuation  in their  market  value.  There is no  limit on the  amount  of the
Trust's  assets  that  may be  invested  in  floating  rate  and  variable  rate
obligations that meet the  requirements of Rule 2a-7.  Floating rate or variable
rate  obligations  which do not provide for recovery of  principal  and interest
within  seven days may be  subject to the  limitations  applicable  to  illiquid
securities  described  in  "Investment  Objective  and  Policies - Illiquid  and
Restricted Securities" in the Prospectus.

When-Issued and Delayed Delivery Transactions.  As stated in the Prospectus, the
Trust  may  invest  in  municipal  securities  on a  "when-issued"  or  "delayed
delivery" basis. Payment for and delivery of the securities shall not exceed 120
days from the date the offer is accepted. The purchase price and yield are fixed
at the time the buyer enters into the commitment.  During the period between the
time of commitment and settlement, no payment is made by the Trust to the issuer
and no interest  accrues to the Trust from this investment.  However,  the Trust
intends to be as fully  invested as possible and will not invest in  when-issued
securities  if its  income  or net  asset  value  will be  materially  adversely
affected.  At the time the Trust  makes the  commitment  to purchase a municipal
security on a when-issued basis, it will record the transaction on its books and
reflect the value of the security in  determining  its net asset value.  It will
also segregate cash or other liquid high quality  municipal  securities equal in
value  to the  commitment  for the  when-issued  securities.  While  when-issued
securities  may be sold prior to settlement  date,  the Trust intends to acquire
the  securities  upon  settlement  unless a prior  sale  appears  desirable  for
investment reasons.  There is a risk that the yield available in the market when
delivery occurs may be higher than the yield on the security acquired.

Repurchase  Agreements.  In a  repurchase  transaction,  the  Trust  acquires  a
security  from,  and  simultaneously  resells it to, an approved  vendor (a U.S.
commercial  bank or the U.S.  branch of a foreign  bank  having  total  domestic
assets of at least $1 billion or a broker-dealer  with a net capital of at least
$50  million  and  which has been  designated  a  primary  dealer in  government
securities).  The resale  price  exceeds  the  purchase  price by an amount that
reflects an agreed-upon  interest rate effective for the period during which the
repurchase  agreement is in effect.  The majority of these transactions run from
day to day, and delivery  pursuant to the resale typically will occur within one
to five days of the purchase. Repurchase agreements are considered "loans" under
the Investment  Company Act of 1940, as amended (the  "Investment  Company Act")
collateralized by the underlying  security.  The Trust's  repurchase  agreements
require that at all times while the repurchase agreement is in effect, the value
of  the  collateral  must  equal  or  exceed  the  repurchase   price  to  fully
collateralize the repayment obligation.  Additionally,  the Manager will monitor
the vendor's  creditworthiness  to confirm that the vendor is financially  sound
and will continuously monitor the collateral's value.

Loans of Portfolio Securities.  To attempt to increase its income, the Trust may
lend its portfolio  securities to qualified  borrowers (other than in repurchase
transactions).  There are risks in connection with securities lending. The Trust
might experience a delay in receiving additional collateral to secure a loan, or
a delay in  recovery  of the loaned  securities.  The Trust  presently  does not
intend to lend securities;  but if it does, these loans cannot exceed 25% of the
value of the  Trust's  total  assets.  Income  from  securities  loans  does not
constitute   exempt-interest   income  for  the  purpose  of  paying  tax-exempt
dividends.

      The Trust 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
Trust is permitted to invest. To be acceptable as collateral,  letters of credit
must  obligate a bank to pay amounts  demanded by the Trust 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 Trust.

      When  it  lends  securities,  the  Trust  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 Trust may pay
reasonable  finder's,  administrative  or other  fees in  connection  with these
loans.  The terms of the  Trust's  loans must meet  applicable  tests  under the
Internal Revenue Code and must permit the Trust to reacquire  loaned  securities
on five days' notice or in time to vote on any important matter.


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.

      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.


Investment Restrictions

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

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

      The Trust'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 Trust's Board of Trustees
can change  non-fundamental  policies  without  shareholder  approval.  However,
significant  changes to investment  policies will be described in supplements or
updates to the  Prospectus  or this  Statement  of  Additional  Information,  as
appropriate.  The Trust's most significant  investment policies are described in
the Prospectus.

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

      |_| The Trust cannot make loans,  except that the Trust, may purchase debt
securities   described  in  "Investment   Objective  and  Policies,"  and  other
securities  substantially  similar thereto, and repurchase  agreements;  and the
Trust may lend its portfolio  securities as described in its  investment  policy
stated above;

      |_| The  Trust  cannot  borrow  money in excess of 10% of the value of its
total assets or make any investment  when  borrowings  exceed 5% of the value of
its total assets; it may borrow only as a temporary measure for extraordinary or
emergency purposes; no assets of the Trust may be pledged, mortgaged or assigned
to secure a debt;

      |_| The Trust  cannot  enter into a  repurchase  agreement  or  purchase a
security  subject to a call if the scheduled  repurchase  or redemption  date is
greater than one year;


      |_| The Trust  cannot  invest more than 25% of its total assets in any one
industry; however for the purposes of this restriction, municipal securities and
U.S.  government  obligations  are  not  considered  to be  part  of any  single
industry;


      |_| The Trust cannot  invest in any debt  instrument  having a maturity in
excess of one year from the date of  purchase,  unless  purchased  subject  to a
demand  feature  which may not exceed one year and requires  payment on not more
than 30 days' notice;

         |_| The  Trust  cannot  invest  more  than 5% of the value of its total
assets in  securities  of companies  that have  operated  less than three years,
including the operations of predecessors;

      |_| The Trust cannot  invest in  commodities  or commodity  contracts,  or
invest in interests in oil, gas, or other  mineral  exploration  or  development
programs;

      |_| The  Trust  cannot  invest  in real  estate;  however,  the  Trust may
purchase Municipal Bonds or Notes secured by interests in real estate;

      |_| The Trust cannot make short sales of securities or purchase securities
on  margin,  except  for  short-term  credits  necessary  for the  clearance  of
purchases and sales of portfolio securities;

      |_| The Trust cannot  invest in or hold  securities of any issuer if those
officers and Trustees of the Trust or the Manager  individually owning more than
0.5%  of the  securities  of  such  issuer  together  own  more  than  5% of the
securities of such issuer;

      |_|   The Trust cannot underwrite securities of other companies;

      |_| The Trust cannot invest in securities  of other  investment  companies
except as they may be acquired as part of a merger, consolidation or acquisition
of assets; or

      |_| The Trust cannot issue "senior securities," but this does not prohibit
certain  investment  activities  for which assets of the Trust are designated as
segregated,  or margin,  collateral or escrow  arrangements are established,  to
cover the related obligations.


      For  purposes  of  the   investment   restrictions   listed   above,   the
identification of the "issuer" of a municipal  security depends on the terms and
conditions  of  the  security.  When  the  assets  and  revenues  of an  agency,
authority,  instrumentality  or other  political  subdivision  are separate from
those of the government creating the subdivision and the security is backed only
by the assets and revenues of the subdivision,  such subdivision would be deemed
to be the sole issuer. Similarly, in the case of an industrial development bond,
if that bond is backed only by the assets and  revenues  of the  nongovernmental
user,  then such  nongovernmental  user  would be deemed to be the sole  issuer.
However,  if in  either  case  the  creating  government  or some  other  entity
guarantees the security,  such guarantee would be considered a separate security
and would be treated as an issue of such  government  or other  agency.  Conduit
securities  are deemed to be issued by the  person  ultimately  responsible  for
payments of interest and principal on the security.

      In applying the  restrictions as to the Trust's  investments,  the Manager
will  consider a  nongovernmental  user of  facilities  financed  by  industrial
development bonds as being in a particular industry, despite the fact that there
is no industry concentration limitation as to municipal securities the Trust may
own.  Although  this  application  of  the  restriction  is  not  technically  a
fundamental  policy of the  Trust,  it will not be changed  without  shareholder
approval.  Should any such change be made,  the Prospectus  and/or  Statement of
Additional Information will be supplemented to reflect the change.


      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 Trust makes an  investment.  The Trust need not sell  securities to
meet  the  percentage  limits  if the  value  of  the  investment  increases  in
proportion to the size of the Trust.

      For purposes of the Trust's policy not to concentrate  its  investments in
securities of issuers,  the Trust has adopted the industry  classifications  set
forth in Appendix B to this Statement of Additional  Information.  This is not a
fundamental policy.

                            How the Trust Is Managed


Organization and History. The Trust is an open-end,  non-diversified  management
investment company organized as a Massachusetts  business trust in 1989, with an
unlimited number of authorized shares of beneficial interest.


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

      |X|  Classes of Shares.  The Trust has a single  class of shares of stock.
While that class has no designation,  it is deemed to be the equivalent of Class
A for purposes of the shareholder  account policies that apply to Class A shares
of the  Oppenheimer  funds.  Shares of the Trust are freely  transferable.  Each
share  has one vote at  shareholder  meetings,  with  fractional  shares  voting
proportionally  on matters  submitted  to a vote of  shareholders.  There are no
preemptive or conversion rights and shares participate  equally in the assets of
the Trust upon liquidation.

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

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

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


      The Trust's contractual  arrangements state that any person doing business
with the Trust (and each  shareholder of the Trust) agrees under the Declaration
of Trust to look solely to the assets of the Trust for satisfaction of any claim
or demand that may arise out of any dealings with the Trust.  Additionally,  the
Trustees  shall have no personal  liability  to any such  person,  to the extent
permitted by law.

   1.  For the 1998 calendar year.

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

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


      |X| Major  Shareholders.  As of October 21, 1999 the only person who owned
of  record  or was  known  by the  Trust to own  beneficially  5% or more of the
Trust's outstanding retail shares was A.G. Edwards & Sons, Inc.  ("Edwards"),  1
North Jefferson Avenue, St. Louis,  Missouri 63103, which owned  164,662,336.830
shares of the Trust  which was 99.3% of the  outstanding  shares of the Trust on
that date,  for accounts of its customers none of whom  individually  owned more
than 5% of the outstanding shares.


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


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


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


      Expenses  not  expressly  assumed  by the  Manager  under  the  investment
advisory  agreement are paid by the Trust.  The  investment  advisory  agreement
lists  examples of expenses paid by the Trust.  The major  categories  relate to
interest,  taxes,  fees to  unaffiliated  Trustees,  legal and  audit  expenses,
custodian and transfer agent expenses,  share issuance costs,  certain  printing
and registration costs and non-recurring  expenses,  including litigation costs.
The management fees paid by the Trust to the Manager are calculated at the rates
described in the Prospectus.

  Fiscal Year    Management Fee Paid to Centennial Asset Management Corporation
  ending 6/30
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

      1997                                  $644,397

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

      1998                                  $801,264

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

      1999                                  $841,379

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


      The Manager has undertaken  that the total  expenses of the Trust,  in any
fiscal year of the Trust,  exclusive of taxes,  interest,  brokerage commissions
(if any) and  non-recurring  expenses,  including  litigation,  shall not exceed
0.80% of the  average  annual  net  assets  of the  Trust.  The  payment  of the
management fee at the end of any month will be reduced so that there will not be
any accrued but unpaid liability under those expense limitations. Any assumption
of the  Trust's  expenses  under this  arrangement  lowers the  Trust's  overall
expense  ratio and  increases  its yield and total  return  during the time such
expenses  are  assumed.  The  Manager  reserves  the right to vary the amount of
expenses  assumed or eliminate the  assumption of expenses  altogether.  For the
fiscal  years  ended  June 30,  1997,  June  30,  1998,  and  June 30,  1999 the
management  fees  payable by the Trust would have been  $644,397,  $801,264  and
$824,512, respectively without the Manager's voluntary expense assumption. Those
amounts do not reflect the effect of the expense  assumptions of $7,679,  $2,862
and $16,867, respectively, in those periods by the Manager.


    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  resulting  from a good faith
error or  omission  on its part  with  respect  to any of its  duties  under the
agreement.

      |X| The Distributor.  Under its General  Distributor's  Agreement with the
Trust,  Centennial  Asset Management  Corporation acts as the Trust's  principal
underwriter  and  Distributor in the continuous  public  offering of the Trust's
shares.  The  Distributor is not obligated to sell a specific  number of shares.
The Distributor  bears the expenses  normally  attributable to sales,  including
advertising and the cost of printing and mailing prospectuses,  other than those
furnished to existing shareholders.

Portfolio  Transactions.  Portfolio decisions are based upon recommendations and
judgment  of the  Manager  subject  to the  overall  authority  of the  Board of
Trustees.  Most  purchases made by the Trust are principal  transactions  at net
prices,  so the Trust  incurs  little or no  brokerage  costs.  The Trust  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.  Purchases  of  portfolio  securities  from  underwriters
include a commission or concession  paid by the issuer to the  underwriter,  and
purchases from dealers include a spread between the bid and asked prices.


      The Trust seeks to obtain prompt execution of orders at the most favorable
net price. If broker/dealers are used for portfolio  transactions,  transactions
may be directed to broker/dealers for their execution and 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 for the commissions of those other accounts may be useful both
to the  Trust  and  one or  more of such  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. It may include  information and analyses
on particular  companies and industries as well as market or economic trends and
portfolio  strategy,  receipt of market  quotations  for portfolio  evaluations,
information systems,  computer hardware and similar products and services.  If a
research  service also assists the Manager in a  non-research  capacity (such as
bookkeeping  or other  administrative  functions),  then only the  percentage or
component   that  provides   assistance   to  the  Manager  in  the   investment
decision-making process may be paid in commission dollars.


      The 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  obtain  market
information  for the  valuation of securities  held in the Trust's  portfolio or
being considered for purchase.

      Subject to  applicable  rules  covering the  Manager's  activities in this
area, sales of shares of the Trust and/or the other investment companies managed
by the Manager or  distributed  by the  Distributor  may also be considered as a
factor  in the  direction  of  transactions  to  dealers.  That  must be done in
conformity  with the price,  execution  and other  considerations  and practices
discussed  above.  Those  other  investment  companies  may  also  give  similar
consideration  relating  to  the  sale  of  the  Trust's  shares.  No  portfolio
transactions  will be  handled  by any  securities  dealer  affiliated  with the
Manager.


      The  Trust's  policy of  investing  in  short-term  debt  securities  with
maturities  of less than one year  results in high  portfolio  turnover  and may
increase the Trust's transaction costs. However, since brokerage commissions, if
any, are small,  high turnover does not have an appreciable  adverse effect upon
the income of the Trust.

Service Plan

The Trust has adopted a Service Plan for the shares.  The plan has been approved
by a vote of the Board of  Trustees,  including  a majority  of the  Independent
Trustees2,  cast in person at a meeting called for the purpose of voting on that
plan.

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

      The Board of  Trustees  and the  Independent  Trustees  must  approve  all
material amendments to a plan. An amendment to increase materially the amount of
payments to be made under a plan must be approved by  shareholders  of the class
affected by the  amendment.  The approval must be by a "majority" (as defined in
the Investment Company Act) of the shares.

2. In  accordance  with  Rule  12b-1 of the  Investment  Company  Act,  the term
"Independent  Trustees" in this  Statement of Additional  Information  refers to
those  Trustees  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 any agreement under the plan.

      While the plan is in effect,  the  Treasurer  of the Trust  shall  provide
separate written reports on the plan to the Board of Trustees 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 Trustees.

      The plan states that while it is in effect,  the selection and  nomination
of those Trustees of the Trust who are not "interested  persons" of the Trust is
committed to the discretion of the Independent  Trustees.  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 Trustees.

      Under the plan, no payment will be made to any recipient in any quarter in
which the  aggregate  net asset value of all Trust 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 Trustees. The Board of
Trustees has set no minimum  amount of assets to qualify for payments  under the
plan.

      |X| Service Plan Fees.  Under the service plan, the Distributor  currently
uses the fees it  receives  from the  Trust to pay  brokers,  dealers  and other
financial  institutions  (they are  referred to as  "recipients")  for  personal
services and account  maintenance  services they provide for their customers who
hold shares.  The services include,  among others,  answering customer inquiries
about the Trust,  assisting  in  establishing  and  maintaining  accounts in the
Trust,  making the  Trust's  investment  plans  available  and  providing  other
services  at the  request  of the Trust or the  Distributor.  The  service  plan
permits  reimbursements  to the  Distributor at a rate of up to 0.20% of average
annual net assets of the shares.  While the plan  permits the Board to authorize
payments to the Distributor to reimburse itself for services under the plan, the
Board has not yet done so. The  Distributor  makes  payments to plan  recipients
quarterly at an annual rate not to exceed 0.20% of the average annual net assets
consisting of shares held in the accounts of the recipients or their customers.

      For the fiscal year ended June 30, 1999  payments  under the plan  totaled
$336,555, all of which was paid by the Distributor to recipients.  That included
$55 paid to an affiliate of the Distributor's  parent company.  Any unreimbursed
expenses  the  Distributor  incurs with respect to the shares in any fiscal year
cannot be recovered in subsequent  years.  The  Distributor may not use payments
received under the plan to pay any of its interest  expenses,  carrying charges,
or other financial costs, or allocation of overhead.


                            Performance of the Trust


Explanation  of  Performance  Terminology.  The Trust uses a variety of terms to
illustrate its performance.  These terms include "yield," "compounded  effective
yield,  "   "tax-equivalent   yield"  and  "average  annual  total  return."  An
explanation  of how yields and total returns are  calculated is set forth below.
The charts  below show the Trust's  performance  as of the  Trust's  most recent
fiscal year end. You can obtain current  performance  information by calling the
Trust's Transfer Agent at 1-800-525-9310.


      The Trust'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.  If the Trust  shows total  returns in  addition to its yields,  the
returns must be for the 1-, 5- and 10-year  periods ending as of the most recent
calendar  quarter  prior  to  the  publication  of  the  advertisement  (or  its
submission for publication).

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

     |_| Yields and total  returns  measure the  performance  of a  hypothetical
account in the Trust 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 than the
shares used in the model.

     |_| An  investment  in the  Trust is not  insured  by the FDIC or any other
government agency.

     |_| The Trust's yield is not fixed or guaranteed and will fluctuate.

     |_| 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.

        |_| Yields.  The Trust's  current  yield is  calculated  for a seven-day
period of time as follows.  First,  a base period return is  calculated  for the
seven-day  period by  determining  the net change in the value of a hypothetical
pre-existing  account having one share at the beginning of the seven-day period.
The change  includes  dividends  declared on the  original  share and  dividends
declared  on any  shares  purchased  with  dividends  on that  share,  but  such
dividends  are adjusted to exclude any realized or  unrealized  capital gains or
losses  affecting  the  dividends  declared.  Next,  the base  period  return is
multiplied by 365/7 to obtain the current yield to the nearest  hundredth of one
percent.

      The compounded effective yield for a seven-day period is calculated by (1)
      adding 1 to the base period  return  (obtained  as described  above),  (2)
      raising the sum to a power equal to 365 divided by 7, and (3)  subtracting
      1 from the result.

      The  yield  as   calculated   above  may  vary  for  accounts   less  than
approximately  $100 in value  due to the  effect  of  rounding  off  each  daily
dividend  to the  nearest  full cent.  The  calculation  of yield  under  either
procedure  described  above does not take into  consideration  any  realized  or
unrealized gains or losses on the Trust's portfolio  securities which may affect
dividends.  Therefore,  the return on dividends declared during a period may not
be the same on an annualized basis as the yield for that period.

      The Trust's "tax  equivalent  yield" adjusts the Trust's current yield, as
calculated  above,  by a stated federal tax rate.  The tax  equivalent  yield is
computed by dividing the tax-exempt  portion of the Trust's current yield by one
minus a stated  income tax rate and adding the result to the portion (if any) of
the Trust's current yield that is not tax-exempt.  The tax equivalent  yield may
be  compounded  as  described  above  to  provide  a  compounded  effective  tax
equivalent yield.


      The Trust's tax equivalent yield may be used to compare the tax effects of
income  derived from the Trust with income from taxable  investments  at the tax
rates stated.  Exhibit D includes a tax equivalent yield table, based on various
effective  tax  brackets  for  individual  taxpayers.   Such  tax  brackets  are
determined by a taxpayer's  federal  taxable  income (the net amount  subject to
federal income tax after  deductions and  exemptions).  The tax equivalent yield
table assumes that the investor is taxed at the highest  bracket,  regardless of
whether a switch to non-taxable investments would cause a lower bracket to apply
and that state income tax payments are fully deductible for income tax purposes.
For taxpayers with income above certain  levels,  otherwise  allowable  itemized
deductions  are  limited.  The Trust's tax  equivalent  yield for the  seven-day
period ended June 30, 1999 was 4.27%. Its  tax-equivalent  compounded  effective
yield for the same period was 4.31% for an  investor in the highest  federal tax
bracket.




      [_] Total Return Information. There are different types of "total returns"
to measure the  Trust's  performance.  Total  return is the change in value of a
hypothetical  investment  in the Trust 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.  The  cumulative
total return  measures the change in value over the entire  period (for example,
ten years).  An average annual total return shows the average rate of return for
each year in a period that would  produce the  cumulative  total return over the
entire  period.  However,  average  annual  total  returns  do not  show  actual
year-by-year performance. The Trust uses standardized calculations for its total
returns as prescribed by the SEC. The methodology is discussed below.

         |_| 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

      |X| Other  Performance  Comparisons.  Yield  information  may be useful to
investors in reviewing the Trust's  performance.  The Trust may make comparisons
between its yield and that of other investments,  by citing various indices such
as The Bank Rate Monitor  National Index  (provided by Bank Rate MonitorJ) which
measures the average rate paid on bank money market  accounts,  NOW accounts and
certificates  of deposits  by the 100  largest  banks and thrifts in the top ten
metro areas.  When  comparing the Trust's yield with that of other  investments,
investors should  understand that certain other investment  alternatives such as
certificates of deposit, U.S. government securities, money market instruments or
bank accounts may provide fixed yields and may be insured or guaranteed.

      From time to time, the Trust may include in its  advertisements  and sales
literature performance information about the Trust cited in other newspapers and
periodicals,  such  as  The  New  York  Times,  which  may  include  performance
quotations from other sources.


      From time to time, the Trust's Manager may publish  rankings or ratings of
the Manager (or the Transfer Agent) or the investor  services  provided by them.
Those ratings or rankings of investor/shareholder  services by third parties may
compare the services provided to those of other mutual fund families selected by
the rating or ranking services.  They may be based on the opinions of the rating
or ranking  service  itself,  based on its  research  or  judgment,  or based on
surveys of investors, brokers, shareholders or others.

                                How to Buy Shares


Determination of Net Asset Value Per Share. The net asset value per share of the
Trust is determined twice each day that the New York Stock Exchange ("Exchange")
is open,  at 12:00 Noon and at 4:00 P.M, on each day that the  Exchange is open,
by dividing  the value of the  Trust's net assets by the total  number of shares
outstanding.  All references to time in this Statement of Additional Information
mean New York time. The  Exchange's  most recent annual  announcement  (which is
subject to change)  states that it will close on New Year's Day,  Martin  Luther
King Jr. Day,  Presidents'  Day, Good Friday,  Memorial Day,  Independence  Day,
Labor Day, Thanksgiving Day and Christmas Day. It may also close on other days.

      The Trust's  Board of Trustees  has adopted the  amortized  cost method to
value the Trust's  portfolio  securities.  Under the  amortized  cost method,  a
security is valued  initially at its cost and its  valuation  assumes a constant
amortization  of any premium or accretion  of any  discount,  regardless  of the
impact of fluctuating  interest rates on the market value of the security.  This
method does not take into  consideration any unrealized  capital gains or losses
on securities.  While this method provides certainty in valuing  securities,  in
certain  periods the value of a security  determined  by  amortized  cost may be
higher or lower than the price the Trust would receive if it sold the security.

      The  Trust's  Board of  Trustees  has  established  procedures  reasonably
designed to  stabilize  the  Trust's  net asset value at $1.00 per share.  Those
procedures  include a review of the valuations of the Trust's portfolio holdings
by the Board of  Trustees,  at  intervals  it deems  appropriate,  to  determine
whether  the  Trust's  net asset  value  calculated  by using  available  market
quotations deviates from $1.00 per share based on amortized cost.

      The Board of Trustees will examine the extent of any deviation between the
Trust's net asset value based upon  available  market  quotations  and amortized
cost.  If the Trust's  net asset  value were to deviate  from $1.00 by more than
0.5%, Rule 2a-7 requires the Board of Trustees to consider what action,  if any,
should be  taken.  If they find  that the  extent of the  deviation  may cause a
material dilution or other unfair effects on shareholders, the Board of Trustees
will take  whatever  steps it considers  appropriate  to eliminate or reduce the
dilution,  including,  among others,  withholding or reducing dividends,  paying
dividends from capital or capital gains, selling portfolio  instruments prior to
maturity to realize  capital gains or losses or to shorten the average  maturity
of the portfolio,  or calculating  net asset value per share by using  available
market quotations.


      During periods of declining  interest rates,  the daily yield on shares of
the Trust may tend to be lower (and net investment  income and dividends higher)
than those of a fund holding the  identical  investments  as the Trust but which
used a method of  portfolio  valuation  based on market  prices or  estimates of
market prices.  During periods of rising interest rates,  the daily yield of the
Trust  would tend to be higher  and its  aggregate  value  lower than that of an
identical portfolio using market price valuation.

How to Sell Shares

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


Checkwriting. When a check is presented to the Bank for clearance, the Bank will
ask the Trust to redeem a sufficient number of full and fractional shares in the
shareholder's  account  to cover  the  amount of the  check.  This  enables  the
shareholder to continue  receiving  dividends on those shares until the check is
presented to the Trust.  Checks may not be presented  for payment at the offices
of the Bank or the Trust's Custodian. This limitation does not affect the use of
checks for the  payment  of bills or to obtain  cash at other  banks.  The Trust
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 Trust 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 the  registered
owner(s);

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

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

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

(6)  acknowledges and agrees that neither the Trust 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.


Sending  Redemption  Proceeds by Federal  Funds Wire.  The Federal Funds wire of
redemptions  proceeds may be delayed if the Trust's  custodian  bank is not open
for  business on a day when the Trust would  normally  authorize  the wire to be
made,  which is usually the Trust'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 Trust is open for business. No distributions
will be paid on the  proceeds of redeemed  shares  awaiting  transfer by Federal
Funds wire


How to Exchange Shares

Centennial Money Market Trust

      Shares of the Trust purchased  without a sales charge may be exchanged for
shares of an eligible fund offered with a sales charge upon payment of the sales
charge.   Shares  of  the  Trust  acquired  by   reinvestment  of  dividends  or
distributions  from the Trust or any of the other  eligible  funds  (other  than
Oppenheimer  Cash  Reserves)  or  from  any  unit  investment  trust  for  which
reinvestment  arrangements  have been made with the Distributor may be exchanged
at net asset value for shares of any of the eligible funds.

      |_| Limits on Multiple  Exchange  Orders.  The Trust reserves the right to
reject  telephone or written  exchange  requests  submitted in bulk by anyone on
behalf of more than one account.  The Trust 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
direct  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 Trust
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 Trust).

      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  eligible  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. The Trust, the Distributor,  the Sub-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.

      The Trust may amend,  suspend or terminate  the exchange  privilege at any
time. Although,  the Trust 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.


                               Dividends and Taxes

Tax Status of the Trust's  Dividends  and  Distributions.  The Trust  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  Trust  on  municipal
securities  will be  excludable  from gross income of  shareholders  for federal
income tax purposes.

      Net  investment  income  includes the allocation of amounts of income from
the  municipal  securities in the Trust'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 Trust'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
Trust's income that was tax-exempt for a given period.

      A portion  of the  exempt-interest  dividends  paid by the Trust 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 Trust.

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

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

(2) income from securities  loans;

(3) income or gains from options or futures; or

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

      The  Trust'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 Trust 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 Trust  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 Trust
to "pass through" its income and realized capital gains to shareholders  without
having to pay tax on them. The Trust 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 Trust qualifies.  The Trust might not meet those
tests in a particular  year.  If it does not qualify,  the Trust 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 Trust qualifies as a regulated investment company
under the Internal  Revenue Code, the Trust 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 Trust's
distributions  are attributable to interest on California  municipal  securities
and qualifying  obligations of the United States government,  if at least 50% of
the Trust's assets are invested in such obligations at the close of each quarter
in its tax year.  Distributions  from the  Trust  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 Trust 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 Trust. Additionally, certain distributions paid to corporate
shareholders  of the Trust may be includable in income subject to the California
alternative minimum tax.

      Under the Internal  Revenue  Code, by December 31 each year the Trust 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 Trust must pay an excise tax on the amounts not distributed. It is
presently anticipated that the Trust will meet those requirements.  However, the
Trust's Board of Trustees and the Manager might  determine in a particular  year
that it would be in the best interest of shareholders not to make  distributions
at the required levels and to pay the excise tax on the  undistributed  amounts.
That  would  reduce  the  amount  of  income  or  capital  gains  available  for
distribution to shareholders.


Dividend  Reinvestment  in Another Trust.  Direct  shareholders of the Trust may
elect to reinvest all dividends  and/or capital gains  distributions  in Class A
shares of any eligible fund listed above. 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.  The investment will be made at the close of business on the payable
date of the dividend or distribution.


                     Additional Information About the Trust


The Distributor.  The Trust's shares are sold through dealers, brokers and other
financial institutions that have a sales agreement with the Sub-Distributor. The
Distributor and the  Sub-Distributor  also distribute  shares of the other funds
managed by the Manager or an affiliate.


The Transfer Agent.  Shareholder  Services,  Inc. the Trust's Transfer Agent, is
responsible  for maintaining  the Trust's  shareholder  registry and shareholder
accounting  records,  and for paying dividends and distributions to shareholders
of  the  Trust.  It  also  handles  shareholder   servicing  and  administrative
functions. It is paid on a "at-cost" basis.

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

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

INDEPENDENT AUDITORS' REPORT
Centennial California Tax Exempt Trust

The Board of Trustees and Shareholders of Centennial California Tax Exempt
Trust:

We have audited the accompanying statement of assets and liabilities,  including
the statement of  investments,  of Centennial  California Tax Exempt Trust as of
June 30, 1999, the related  statement of operations for the year then ended, the
statements  of changes in net assets for the years  ended June 30, 1999 and 1998
and the financial highlights for the period July 1, 1994 to June 30, 1999. These
financial  statements  and financial  highlights are the  responsibility  of the
Trust'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 June
30, 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  Centennial
California Tax Exempt Trust as of June 30, 1999, the results of its  operations,
the changes in its net assets,  and the financial  highlights for the respective
stated periods, in conformity with generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS
Centennial California Tax Exempt Trust

1. SIGNIFICANT ACCOUNTING POLICIES

Centennial  California  Tax Exempt  Trust (the  Trust) is  registered  under the
Investment  Company Act of 1940,  as  amended,  as a  non-diversified,  open-end
management  investment company.  The Trust's investment objective is to seek the
maximum  current  interest  income exempt from Federal and  California  personal
income taxes for  individual  investors as is consistent  with  preservation  of
capital.   The  Trust's   investment  advisor  is  Centennial  Asset  Management
Corporation  (the Manager),  a subsidiary of  OppenheimerFunds,  Inc. (OFI). The
following is a summary of significant  accounting policies consistently followed
by the Trust.

Securities Valuation. Portfolio securities are valued on the basis of amortized
cost, which approximates market value.

Federal  Taxes.  The Trust intends to continue to comply with  provisions of the
Internal  Revenue Code  applicable  to  regulated  investment  companies  and to
distribute all of its taxable income,  to  shareholders.  Therefore,  no federal
income or excise tax provision is required.  As of June 30, 1999,  the Trust had
available for federal  income tax purposes,  an unused capital loss carryover of
approximately $24,000, which expires between 2006 and 2007.

Distributions to Shareholders. Distributions to shareholders, which are
determined in accordance with income tax regulations, are recorded on the
ex-dividend date.

Expense Offset Arrangements. Expenses paid indirectly represent a reduction of
custodian fees for earnings on cash balances maintained by the Trust.

Other. Investment transactions are accounted for as of trade date. Realized
gains and losses on investments 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  event 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.

3. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Management  fees paid to the  Manager  were in  accordance  with the  investment
advisory agreement with the Trust which provides for a fee of 0.50% of the first
$250 million of net assets; 0.475% of the next $250 million of net assets; 0.45%
of the next $250  million of net assets;  0.425% of the next $250 million of net
assets  and  0.40% of net  assets  in  excess of $1  billion.  The  Manager  has
voluntarily  undertaken  to assume Trust  expenses in excess of 0.80% of average
annual net assets.  The Trust's  management fee for the year ended June 30, 1999
was 0.50% of average annual net assets.

Shareholder  Services,  Inc.  (SSI),  a  subsidiary  of OFI, is the transfer and
shareholder  servicing agent for the Trust and for other  registered  investment
companies. SSI's total costs of providing such services are allocated ratably to
these companies.

Under an approved plan of distribution,  the Trust may expend up to 0.20% of its
net assets annually to reimburse the Manager, as distributor, for costs incurred
in connection  with the personal  service and  maintenance of accounts that hold
shares of the Trust, including amounts paid to brokers, dealers, banks and other
institutions.

                                   Appendix A

                        Description of Securities Ratings

Below is a description of the two highest rating  categories for Short Term Debt
and  Long   Term   Debt  by  the   "Nationally-Recognized   Statistical   Rating
Organizations" which the Manager evaluates in purchasing securities on behalf of
the Trust.  The ratings  descriptions  are based on information  supplied by the
ratings organizations to subscribers.

Short-Term Debt Ratings.

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

The following  rating  designations  for commercial paper (defined by Moody's as
promissory  obligations not having original  maturity in excess of nine months),
are  judged by  Moody's  to be  investment  grade,  and  indicate  the  relative
repayment capacity of rated issuers:

Prime-1: Superior capacity for repayment. Capacity will normally be evidenced by
the following characteristics: (a) leveling market positions in well-established
industries;  (b)  high  rates of  return  on funds  employed;  (c)  conservative
capitalization  structures  with  moderate  reliance  on debt  and  ample  asset
protection; (d) broad margins in earning coverage of fixed financial charges and
high internal cash  generation;  and (e) well  established  access to a range of
financial markets and assured sources of alternate liquidity.

Prime-2: Strong capacity for repayment.  This will normally be evidenced by many
of the characteristics  cited above but to a lesser degree.  Earnings trends and
coverage ratios, while sound, will be more subject to variation.  Capitalization
characteristics,  while  still  appropriate,  may be more  affected  by external
conditions. Ample alternate liquidity is maintained.

Moody's  ratings for state and municipal  short-term  obligations are designated
"Moody's Investment Grade" ("MIG").  Short-term notes which have demand features
may also be designated as "VMIG". These rating categories are as follows:

MIG1/VMIG1: Best quality. There is present strong protection by established cash
flows,  superior  liquidity  support or demonstrated  broad-based  access to the
market for refinancing.

MIG2/VMIG2:  High quality. Margins of protection are ample although not so large
as in the preceding group.


<PAGE>


Standard & Poor's Ratings Services
- --------------------------------------------------------------------------------

The following  ratings by Standard & Poor's for commercial paper (defined by S&P
as debt  having  an  original  maturity  of no more than 365  days)  assess  the
likelihood of payment:

A-1:  Strong  capacity for timely  payment.  Those issues  determined to possess
extremely  strong  safety  characteristics  are  denoted  with a plus  sign  (+)
designation.

A-2: Satisfactory  capacity for timely payment.  However, the relative degree of
safety is not as high as for issues designated "A-1".

S&P's ratings for Municipal Notes due in three years or less are:

SP-1: Very strong or strong capacity to pay principal and interest. Those issues
determined to possess  overwhelming safety  characteristics will be given a plus
(+) designation.

SP-2:             Satisfactory capacity to pay principal and interest.

S&P assigns "dual  ratings" to all  municipal  debt issues that have a demand or
double  feature as part of their  provisions.  The first  rating  addresses  the
likelihood  of repayment of principal and interest as due, and the second rating
addresses  only the demand  feature.  With  short-term  demand debt,  S&P's note
rating  symbols  are used  with  the  commercial  paper  symbols  (for  example,
"SP-1+/A-1+").


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

Fitch  assigns the following  short-term  ratings to debt  obligations  that are
payable on demand or have  original  maturities  of generally up to three years,
including  commercial  paper,  certificates of deposit,  medium-term  notes, and
municipal and investment notes:

F-1+: Exceptionally strong credit quality; the strongest degree of assurance for
timely payment.

F-1: Very strong credit  quality;  assurance of timely  payment is only slightly
less in degree than issues rated "F-1+". F-2: Good credit quality;  satisfactory
degree of assurance for timely payment, but the margin of safety is not as great
as for issues assigned "F-1+" or "F-1" ratings.


Duff & Phelps, Inc.
- --------------------------------------------------------------------------------

The  following  ratings are for  commercial  paper  (defined by Duff & Phelps as
obligations  with  maturities,  when  issued,  of under one year),  asset-backed
commercial paper, and certificates of deposit (the ratings cover all obligations
of the institution with maturities,  when issued,  of under one year,  including
bankers' acceptance and letters of credit):

Duff 1+: Highest certainty of timely payment.  Short-term  liquidity,  including
internal  operating  factors and/or access to alternative  sources of funds,  is
outstanding,  and  safety  is just  below  risk-free  U.S.  Treasury  short-term
obligations.

Duff 1: Very high certainty of timely payment.  Liquidity  factors are excellent
and supported by good fundamental protection factors. Risk factors are minor.

Duff 1-: High  certainty  of timely  payment.  Liquidity  factors are strong and
supported by good fundamental protection factors. Risk factors are very small.

Duff 2:  Good  certainty  of  timely  payment.  Liquidity  factors  and  company
fundamentals  are  sound.  Although  ongoing  funding  needs may  enlarge  total
financing  requirements,  access to capital  markets is good.  Risk  factors are
small.


Thomson BankWatch, Inc.
- --------------------------------------------------------------------------------

The following  short-term  ratings apply to commercial  paper,  certificates  of
deposit,  unsecured notes, and other securities having a maturity of one year or
less.

TBW-1:  The highest  category;  indicates the degree of safety  regarding timely
repayment of principal and interest is very strong.

TBW-2: The second highest rating category;  while the degree of safety regarding
timely  repayment of principal  and interest is strong,  the relative  degree of
safety is not as high as for issues rated "TBW-1".

Long Term Debt Ratings

These  ratings  are  relevant  for  securities  purchased  by the  Trust  with a
remaining  maturity  of 397 days or less,  or for rating  issuers of  short-term
obligations.

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

Bonds (including municipal bonds) are rated as follows:

Aaa: Judged to be the best quality. They carry the smallest degree of investment
risk  and are  generally  referred  to as "gilt  edge."  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, such changes
as can be  visualized  are most  unlikely  to impair  the  fundamentally  strong
positions of such issues.

Aa: 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 in
"Aaa"  securities  or  fluctuations  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 in "Aaa" securities.

Moody's  applies  numerical  modifiers  "1",  "2"  and  "3" in its  "Aa"  rating
classification. The modifier "1" indicates that the security ranks in the higher
end of its generic  rating  category;  the  modifier  "2"  indicates a mid-range
ranking; and the modifier "3" indicates that the issue ranks in the lower end of
its generic rating category.

                       Standard & Poor's Ratings Services
- --------------------------------------------------------------------------------

Bonds (including municipal bonds) are rated as follows:

AAA:  The highest  rating  assigned by S&P.  Capacity to pay  interest and repay
principal is extremely strong.

AA: A strong  capacity to pay interest and repay principal and differ from "AAA"
rated issues only in small degree.

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

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

AA:  Considered  to be  investment  grade and of very high credit  quality.  The
obligor's  ability to pay interest and repay principal is very strong,  although
not quite as strong as bonds rated "AAA".  Plus (+) and minus (-) signs are used
in the "AA"  category to indicate the relative  position of a credit within that
category.

Because  bonds  rated in the "AAA"  and "AA"  categories  are not  significantly
vulnerable to foreseeable future developments,  short-term debt of these issuers
is generally rated "F-1+".

                               Duff & Phelps, Inc.
- --------------------------------------------------------------------------------

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

AA: High credit quality.  Protection factors are strong.  Risk is modest but may
vary  slightly  from time to time because of economic  conditions.  Plus (+) and
minus (-) signs are used in the "AA" category to indicate the relative  position
of a credit within that category.

                             Thomson BankWatch, Inc.
- --------------------------------------------------------------------------------

TBW issues  the  following  ratings  for  companies.  These  ratings  assess the
likelihood of receiving  payment of principal and interest on a timely basis and
incorporate  TBW's  opinion as to the  vulnerability  of the  company to adverse
developments,  which may impact the market's perception of the company,  thereby
affecting the marketability of its securities.

A:  Possesses  an  exceptionally  strong  balance  sheet  and  earnings  record,
translating into an excellent  reputation and unquestioned access to its natural
money  markets.  If  weakness  or  vulnerability  exists  in any  aspect  of the
company's   business,   it  is  entirely  mitigated  by  the  strengths  of  the
organization.

A/B: The company is financially  very solid with a favorable track record and no
readily apparent weakness.  Its overall risk profile, while low, is not quite as
favorable as for companies in the highest rating

                           TAX EQUIVALENT YIELD TABLES
- --------------------------------------------------------------------------------


The equivalent  yield tables below compare  tax-free  income with taxable income
under  1999  federal  individual  income tax rates,  and 1998  California  state
individual income tax rates.  "Combined Taxable Income" refers to the net amount
subject to Federal and California  income taxes after deductions and exemptions.
The tables assume that an investor's  highest tax bracket  applies to the change
in taxable  income  resulting  from a switch  between  taxable  and  non-taxable
investments,  and that state tax payments are currently  deductible  for federal
tax  purposes  and  that  the  investor  is not  subject  to  Federal  or  state
alternative  minimum  tax.  The income tax  brackets  are subject to indexing in
future years to reflect changes in the Consumer Price Index. The brackets do not
reflect the phase out of itemized  deductions and personal  exemptions at higher
income  levels,  resulting  in higher  effective  tax rates (and tax  equivalent
yields).  For the years  beginning  after  January  1,  1996,  the top  marginal
California  personal tax rate was reduced to 9.30% and the top combined marginal
tax rate was 45.22%. The 1998 California rates are not yet available.
