The Trust's Investment Objective and Strategies

WHAT IS THE TRUST'S  INVESTMENT  OBJECTIVE?  The Trust seeks the maximum current
income  that  is  consistent  with  low  capital  risk  and the  maintenance  of
liquidity.

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.

WHO IS THE TRUST  DESIGNED  FOR?  The Trust is designed  for  investors  who are
seeking 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 special 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  securities (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.



-------------------------------------------------------------------------------
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 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 last ten
calendar  years and its average annual total returns for the 1-, 5- and 10- year
periods.  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 1/1/00  through  9/30/00 the  cumulative  total  return (not
annualized)  was 4.34%.  During the period  shown in the bar chart,  the highest
return (not  annualized) for a calendar  quarter was 1.0% (1stand 4th Q '90) and
the lowest return (not annualized) for a calendar quarter was 0.65% (1st and 2nd
Q '93).

The returns  measure the  performance of a hypothetical  account and assume that
all dividends have been reinvested in additional shares.

-------------------------------------------------------------------------------
The total returns are not the Trust's current yield. The Trust's yield more
closely reflects the Trust's current earnings.   To obtain the Trust's
current 7-day yield, please call the Transfer Agent toll-free at

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

Fees and Expenses of the Trust

The Trust pays a variety of expenses directly for 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 the fiscal year ended
June 30, 2000.

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                        0.34%

 Total Annual Operating Expenses        0.67%
 -------------------------------------------------------------------
"Other expenses" in the table include  transfer agent fees,  custodial fees, and
accounting and legal expenses the Trust pays.

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:

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.

      The Trust's investment  manager,  Centennial Asset Management  Corporation
(referred  to in this  Prospectus  as the  Manager)  tries  to  reduce  risks by
diversifying  investments and 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.

What  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
      instruments the Trust may invest in.

o     U.S. Government Securities.  The Trust invests in obligations issued or
      guaranteed by the U.S. government or any of its agencies or
      instrumentalities.  Some are direct obligations of the U.S. Treasury,
      such as Treasury bills, notes and bonds, and are supported by the full
      faith and credit of the United States.  Other U.S. government
      securities, such as pass-through certificates issued by the Government
      National Mortgage Association (Ginnie Mae), are also supported by the
      full faith and credit of the U.S. government.  Some government
      securities, agencies or instrumentalities of the U.S. government are
      supported by the right of the issuer to borrow from the U.S. Treasury,
      such as securities of the Federal National Mortgage Corporation (Fannie
      Mae).  Others may be supported only by the credit of the
      instrumentality, such as obligations of the Federal Home Loan Mortgage
      Corporation (Freddie Mac).

o     Bank Obligations.  The Trust can buy time deposits, certificates of
      deposit and bankers' acceptances.  These obligations must be denominated
      in U.S. dollars, even if issued by a foreign bank.

o     Commercial Paper.  Commercial paper is a short-term,  unsecured promissory
      note of a domestic or foreign  company or other  financial firm. The Trust
      may buy  commercial  paper only if it matures in nine  months or less from
      the date of purchase.

o     Corporate Debt Obligations.  The Trust can invest in other short-term
      corporate debt obligations, besides commercial paper including debt
      obligations that either mature within twelve months of the date of
      purchase or that are subject to repurchase agreements that call for
      delivery in twelve months or less.  The Board of Trustees has proposed a
      change to this policy to increase the length of permitted maturity to up
      to the maximum time permitted under Rule 2a-7, which is currently 397
      days.  Please see "What Standards Apply to the Trust's Investment?"
      below for more details.

o     Other  Money  Market  Obligations.  The Trust may  invest in money  market
      obligations  other  than  those  listed  above  if  they  are  subject  to
      repurchase  agreements or guaranteed as to their principal and interest by
      a corporation whose commercial paper may be purchased by the Trust or by a
      domestic bank. The bank must meet credit criteria set by the Board.

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

      Currently,  the Board has  approved  the  purchase  of  dollar-denominated
obligations of foreign banks payable in the U.S. or in London, England, floating
or  variable  rate  demand  notes,   asset-backed  securities,   and  bank  loan
participation agreements.  Their purchase may be subject to restrictions adopted
by the Board from time to time.

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
      Investment  Company Act for money market funds and  procedures  adopted by
      the Board.  The 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. The Trust's  fundamental policy restricting  investments
      in any debt  instrument  having a maturity  in excess of one year from the
      date of the investment is more  restrictive  than the standards that apply
      to all money  market  funds.  That  restriction  could  limit the  Trust's
      investments,  however,  shareholders  have been  requested  to  approve an
      amendment to this policy  whereby no  security's  maturity will exceed the
      maximum time  permitted  under Rule 2a-7. If the change is not approved by
      shareholders,  the Manager will supplement this Prospectus to reflect that
      the  change  was  not  approved.   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 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.  Please  see the
      Statement of Additional  Information for more information on the proposals
      to  change  the  fundamental  policies  that  the  Board of  Trustees  has
      requested  shareholders  to approve.  If  shareholders  do not approve the
      changes, then this Prospectus and Statement of Additional Information will
      be supplemented to advise you that the amendments were not approved.

OTHER  INVESTMENT  STRATEGIES.  To seek its  objective,  the  Trust  can use the
investment techniques and strategies described below. The Trust might not always
use all of them.  These  techniques  involve 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 (or
      if the  proposed  change is approved  by  shareholders,  the maximum  time
      permitted  under Rule 2a-7),  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 (or if the
      proposed  change is approved by  shareholders,  the maximum time permitted
      under Rule 2a-7).

Asset-Backed Securities. The Trust can invest in asset-backed securities.  These
      are  fractional  interests  in pools of  consumer  loans and  other  trade
      receivables,  which are the obligations of a number of different  parties.
      The income from the underlying  pool is passed through to investors,  such
      as the Trust.

      These  investments might be supported by a credit  enhancement,  such as a
letter of  credit,  a  guarantee  or a  preference  right.  However,  the credit
enhancement generally applies only to a fraction of the security's value. If the
issuer of the security has no security interest in the related collateral, there
is the risk that the Trust could lose money if the issuer defaults.

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.

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
      Trust may  invest up to 25% of its net  assets in  restricted  securities,
      subject to the 10% limit on illiquid securities and restricted  securities
      other than those sold 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.

The information  below applies to Centennial Money Market Trust,  Centennial Tax
Exempt Trust and Centennial  Government  Trust. Each is referred to as a "Trust"
and  they  are  collectively  referred  to as  the  "Trusts".  Unless  otherwise
indicated, this information applies to each Trust.

How the Trusts are Managed

THE  MANAGER.   The  Manager,   Centennial  Asset  Management   Corporation,   a
wholly-owned subsidiary of OppenheimerFunds, Inc., is the investment advisor for
the Trusts. The Manager chooses each of the Trust's  investments and handles its
day-to-day business.  The Manager carries out its duties subject to the policies
established  by the Trust's  Board of  Trustees,  under an  investment  advisory
agreement  with each  Trust  that  states the  Manager's  responsibilities.  The
agreement sets the fees the Trust pays to the Manager and describes the expenses
that the Trust is responsible to pay to conduct its business.

      The Manager has been an investment advisor since 1978. The Manager and its
affiliates  managed  investment  companies  and  other  assets of more than $130
billion as of September 30, 2000, and more than 5 million shareholder  accounts.
The Manager is located at 6803 South Tucson Way, Englewood, Colorado 80112.

Portfolio Managers.  The portfolio managers of the Trusts are the persons
      principally responsible for the day-to-day management of the Trust's
      portfolios.  The portfolio manager of Centennial Money Market Trust and
      Centennial Government Trust is Carol E. Wolf.  Ms. Wolf was co-portfolio
      manager of the Trusts from June 1990 until April 2000, when she became
      the sole portfolio manager.  She is a Senior Vice President of
      OppenheimerFunds, Inc. and of the Trusts and an officer and portfolio
      manager of other funds for which the Manager or an affiliate serves as
      investment advisor.  The portfolio manager of Centennial Tax Exempt
      Trust is Michael Carbuto (since October 1987).  Mr. Carbuto is a Vice
      President of OppenheimerFunds, Inc. and is an officer and portfolio
      manager of other funds for which the Manager serves as investment
      advisor.

Advisory Fees.  Under  each  investment  advisory  agreement,  a 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 respective Trust as of the close of each business day.

o     Centennial Money Market Trust.  The annual management fee 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; 0.400% of the next $250 million; 0.375% of the next
      $250 million; 0.350% of the next $500 million; and 0.325% of net assets
      in excess of $2 billion.  In the agreement, the Manager guarantees that
      the Trust's total expenses in any fiscal year, exclusive of taxes,
      interest and brokerage commissions, and extraordinary expenses such as
      litigation costs, shall not exceed the lesser of (1) 1.5% of the average
      annual net assets of the Trust up to $30 million and 1% of its average
      annual net assets in excess of $30 million; or (2) 25% of the total
      annual investment income of the Trust. Centennial Money Market Trust's
      management fee for its fiscal year ended June 30, 2000 was 0.34% of the
      Trust's average annual net assets.

o     Centennial Government Trust.  The annual management fee 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; 0.400% of the next $250 million; 0.375% of the next
      $250 million and 0.350% of net assets in excess of $1.5 billion. The
      Manager has made the same guarantee to Centennial Government Trust
      regarding expenses as described above for Centennial Money Market Trust.
      The Trust's management fee for its fiscal year ended June 30, 2000 was
      0.45% of the Trust's average annual net assets.

o     Centennial Tax Exempt Trust.  The annual management fee rates applicable
      to the Trust are as follows: 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; 0.400% of the next $250
      million; 0.375% of the next $250 million; 0.350% of the next $500
      million; and 0.325% of net assets in excess of $2 billion. Under the
      agreement, when the value of the Trust's net assets is less than $1.5
      billion, the annual fee payable to the Manager shall be reduced by
      $100,000 based on average net assets computed daily and paid monthly at
      the annual rates.  However, the annual fee cannot be less than $0.  The
      Trust's management fee for its fiscal year ended June 30, 2000 was 0.43%
      of the Trust's average annual net assets.


How to Buy Shares

HOW ARE SHARE PRICES DETERMINED? Shares of each 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 a 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.) receives the purchase order
at its offices in 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 a Trust's Net Asset Value Determined?  The net asset value of shares of
      each 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 a
Trust's net assets by the number of shares that are outstanding.  Under a policy
adopted by the Board of Trustees of the  Trusts,  each Trust uses the  amortized
cost method to value its securities to determine net asset value.

     The shares of each 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?  Minimum initial investments  described below and
depend  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 a  Trust  through  a  broker-dealer  that  has a sales
      agreement  with the Trust's  Distributor  or  Sub-Distributor  that allows
      shares  to be  purchased  through  the  dealer's  Automatic  Purchase  and
      Redemption  Program.  Shares of each Trust are sold mainly to customers of
      participating  dealers that offer the Trusts'  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 can buy shares of a 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 a Trust.

AUTOMATIC PURCHASE AND REDEMPTION  PROGRAM. If you buy shares of a 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  Procedures" 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
Trusts'  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
      a 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 a Trust.

o     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.

o     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.

o     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 can buy shares of a
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.

      Each 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 a 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 a 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 a 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.  Each 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 (together with
      significant  amounts from the  Manager's  own  resources)  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.

Retirement Plans. Direct shareholders may buy shares of a Trust for a retirement
      plan account. If you participate in a plan sponsored by your employer, the
      plan trustee or  administrator  must buy the shares for your plan account.
      The  Sub-Distributor  also offers a number of different  retirement  plans
      that individuals and employers can use:
o     Individual Retirement Accounts (IRAs).  These include regular IRAs, Roth
      IRAs, rollover IRAs and Education IRAs.
o     SEP-IRAs.  These  are  Simplified  Employee  Pensions  Plan IRAs for small
      business owners or self-employed individuals.
o     403(b)(7)  Custodial Plans.  These are tax deferred plans for employees of
      eligible  tax-exempt  organizations,   such  as  schools,   hospitals  and
      charitable organizations.
o     401(k) Plans.  These are special retirement plans for businesses.
o     Pension and Profit-Sharing Plans.  These plans are designed for
      businesses and self-employed individuals.

      Please call the  Sub-Distributor  for  retirement  plan  documents,  which
include applications and important plan information.

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

      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 Telephone?  Direct shareholders and
      their dealer  representative  of record may sell shares by  telephone.  To
      receive the redemption price  calculated on a particular  regular business
      day, the Transfer Agent or its  designated  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.

Retirement Plan Accounts.  There are special procedures to sell shares held in a
      retirement  plan  account.  Call the  Transfer  Agent  for a  distribution
      request  form.  Special  income  tax  withholding  requirements  apply  to
      distributions  from retirement  plans.  You must submit a withholding form
      with your  redemption  request to avoid delay in getting your money and if
      you do not want tax withheld.  If your employer holds your retirement plan
      account for you in the name of the plan,  you must ask the plan trustee or
      administrator  to  request  the  sale of the  Trust  shares  in your  plan
      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.  If  checkwriting  is  established  after
November 1, 2000,  only one  signature is required for  shareholders  with joint
accounts, unless you elect otherwise.

   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 of a Trust that were bought directly or by reinvesting
distributions from that Trust or another Centennial Trust or eligible fund.
Generally, there is no fee to redeem shares of a Trust bought by exchange of
shares of another Centennial Trust or eligible fund.  However,

o     if you acquired shares of a Trust by exchanging  Class A shares of another
      eligible fund that you bought  subject to the Class A contingent  deferred
      sales charge, and
o     those shares are still  subject to the Class A contingent  deferred  sales
      charge when you exchange them into the Trust, then
o     you will 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 a 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 a 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 whose shares
      you purchase by exchange.
   o Before exchanging into a fund, you must obtain and read its prospectus.

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

      You may pay a sales  charge when you exchange  shares of a Trust.  Because
shares of the Trusts are sold without sales charge,  in some cases you may pay a
sales  charge when you exchange  shares of a 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 a Trust purchased by reinvesting  distributions from
that Trust or other eligible funds (except  Oppenheimer Cash Reserves),  or when
you  exchange  shares of a 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 a 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 a 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 Trusts  reserve the right to refuse any exchange  request that may, in
      the  opinion of the  Trusts,  be  disadvantageous,  or to refuse  multiple
      exchange requests submitted by a shareholder or dealer.

   o  The Trusts may amend,  suspend or terminate the exchange  privilege at any
      time. The Trusts will provide you notice  whenever they are required to do
      so by  applicable  law, but they 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 Trusts' policies and procedures for buying,  selling
and exchanging shares is contained in the Statement of Additional Information.

The   offering of shares of a 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 a Trust's best interest to do so.

Telephone transaction privileges for purchases,  redemptions or exchanges may be
      modified,  suspended or  terminated  by a Trust at any time. If an account
      has more than one owner,  a 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 Trusts 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 the redemption of 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 Centennial Tax Exempt
      Trust if the account  value has fallen  below $500 for reasons  other than
      the fact  that the  market  value of shares  has  dropped.  In some  cases
      involuntary   redemptions   may  be  made  to  repay  the  Distributor  or
      Sub-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  prospectus,  annual and semi-annual  report to
      shareholders having the same last name and address on the Trust's records.
      The  consolidation of these mailings,  called  householding,  benefits the
      Trust through reduced mailing expense.

      If you want to receive  multiple copies of these  materials,  you may call
      the  Transfer  Agent at  1.800.525.9310.  You may also notify the Transfer
      Agent in writing.  Individual  copies of prospectuses  and reports will be
      sent to you within 30 days after the Transfer  Agent receives your request
      to stop householding.

Dividends and Tax Information

DIVIDENDS.  Each Trust intends to declare  dividends from net investment  income
each regular business day and to pay those dividends to shareholders  monthly on
a date selected by the Board of Trustees. To maintain a net asset value of $1.00
per share, a 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 a Trust from the purchase
payment for such shares.

CAPITAL  GAINS.  Each  Trust  normally  holds its  securities  to  maturity  and
therefore  will not usually pay capital  gains.  Although the Trusts do not seek
capital gains, a 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. A 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 some
      distributions  (dividends,  short-term  capital gains or long-term capital
      gains distributions) in the selected Trust.
o     Reinvest  Capital Gains Only. You can elect to reinvest some capital gains
      distributions  (dividends,  short-term  capital gains or long-term capital
      gains  distributions)  in the selected 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 (dividends,
      short-term capital gains or long-term capital gains  distributions)  check
      for all distributions or have them sent to your bank.
o     Reinvest  Your  Distributions  in Another  Account.  You can  reinvest all
      distributions  (dividends,  short-term  capital gains or long-term capital
      gains  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.

Centennial Money Market Trust and Centennial  Government  Trust.  If your shares
      are not held in a tax-deferred  retirement account, you should be aware of
      the following  tax  implications  of investing in Centennial  Money Market
      Trust and Centennial Government Trust.  Dividends paid from net investment
      income  and  short-term  capital  gains are  taxable as  ordinary  income.
      Long-term  capital  gains are  taxable  as  long-term  capital  gains when
      distributed  to  shareholders.  It does not  matter how long you have held
      your shares.  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 each  taxable  distribution  you received in the  previous  year.  Any
long-term capital gains  distributions will be separately  identified in the tax
information the Trust sends you after the end of the calendar year.

Centennial Tax Exempt Trust.  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 and capital gains distributions may be subject to state or local
taxes.  Long-term  capital  gains are taxable as  long-term  capital  gains when
distributed  to  shareholders.  It does not  matter  how long you have held your
shares.  Dividends  paid from  short-term  capital gains and non-tax  exempt net
investment  income 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  each  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 a 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 a Trust on your particular tax situation.

Financial Highlights

The  Financial  Highlights  Tables are  presented  to help you  understand  each
Trust's  financial   performance  for  the  past  five  fiscal  years.   Certain
information  reflects  financial  results for a single  Trust  share.  The total
returns in the tables  represent the rate that an investor would have earned (or

The Trust's Investment Objective and Strategies

WHAT IS THE TRUST'S  INVESTMENT  OBJECTIVE?  The Trust seeks the maximum current
income  that  is  consistent  with  low  capital  risk  and the  maintenance  of
liquidity.

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.

WHO IS THE TRUST  DESIGNED  FOR?  The Trust is designed  for  investors  who are
seeking 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 special 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 securities (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.

-------------------------------------------------------------------------------
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 Past Performance

The bar chart and table below show how the  Trust's  returns may vary over time,
by showing  changes in the  performance  for a class of shares of the Trust from
year to year for the last ten calendar years and average annual total returns on
that share class offered prior to the date of this prospectus for the 1-, 5- and
10- year periods. Because Class Y shares have not been offered prior to the date
of this prospectus, information in the bar chart and the table show below is for
the Trust's  existing  share  class.  That share  class has no  alphabet  letter
designation  and is referred to in this  Prospectus as the Trust's "retail share
class." The retail share class is offered by a separate prospectus.  Variability
of returns is one measure of the risks of investing in a money market fund.  The
past investment performance of the share class shown below is not necessarily an
indication  of how  either of the  Trust's  share  classes  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 1/1/00  through  9/30/00 the  cumulative  total  return (not
annualized)  was 4.34%.  During the period  shown in the bar chart,  the highest
return (not  annualized) for a calendar  quarter was 1.0% (1stand 4th Q '90) and
the lowest return (not annualized) for a calendar quarter was 0.65% (1st and 2nd
Q '93).

The returns  measure the  performance of a hypothetical  account and assume that
all dividends have been reinvested in additional shares.

The total  returns are not the Trust's  current  yield.  The Trust's  yield more
closely  reflects the Trust's  current  earnings.  To obtain the Trust's current

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

Fees and Expenses of the Trust

The Trust pays a variety of expenses directly for 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  provided  to help you
understand  the fees and expenses you may pay if you buy and hold Class Y shares
of the Trust.  The  numbers  below are based upon the Trust's  expenses  for its
retail share class  during the fiscal year ended June 30,  2000.  Class Y shares
were not offered during the fiscal year ended June 30, 2000.

SHAREHOLDER FEES.  The Trust does not charge any shareholder fees in
connection with the offer of its Class Y shares.

Annual Trust Operating Expenses (deducted from Trust assets):

 -------------------------------------------------------------------
 -------------------------------------------------------------------
 Total Annual Operating Expenses        0.37%
 -------------------------------------------------------------------
"Other expenses" in the table include  transfer agent fees,  custodial fees, and
accounting and legal expenses the Trust pays.

The Annual Operating Expenses are estimated based on the expenses of the Trust's
retail  share class during the Trust's  fiscal year ended June 30,  2000.  It is
anticipated  that  expenses of the Trust's Class Y shares will be lower than the
Trust's  retail share class because Class Y shares will not incur a service plan
fee and transfer agency expenses  (included in "Other Expenses") are anticipated
to be lower for Class Y shares.

EXAMPLE.  This  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 and  reinvest  your
dividends and distributions. The example also assumes that your investment has a
5% return each year and that the Trust's  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:

  ------------------------------------------------------------------
                            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.

      The Trust's investment  manager,  Centennial Asset Management  Corporation
(referred  to in this  Prospectus  as the  Manager)  tries  to  reduce  risks by
diversifying  investments and 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.

What  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
      instruments the Trust may invest in.

o     U.S. Government Securities.  The Trust invests mainly in obligations
      issued or guaranteed by the U.S. government or any of its agencies or
      instrumentalities.  Some are direct obligations of the U.S. Treasury,
      such as Treasury bills, notes and bonds, and are supported by the full
      faith and credit of the United States.  Other U.S. government
      securities, such as pass-through certificates issued by the Government
      National Mortgage Association (Ginnie Mae), are also supported by the
      full faith and credit of the U.S. government.  Some government
      securities, agencies or instrumentalities of the U.S. government are
      supported by the right of the issuer to borrow from the U.S. Treasury,
      such as securities of the Federal National Mortgage Corporation (Fannie
      Mae).  Others may be supported only by the credit of the
      instrumentality, such as obligations of the Federal Home Loan Mortgage
      Corporation (Freddie Mac).

o     Bank Obligations.  The Trust can buy time deposits, certificates of
      deposit and bankers' acceptances.  These obligations must be denominated
      in U.S. dollars, even if issued by a foreign bank.

o     Commercial Paper.  Commercial paper is a short-term,  unsecured promissory
      note of a domestic or foreign  company or other  financial firm. The Trust
      may buy  commercial  paper only if it matures in nine  months or less from
      the date of purchase.

o     Corporate Debt Obligations.  The Trust can invest in other short-term
      corporate debt obligations, besides commercial paper including debt
      obligations that either mature within twelve months of the date of
      purchase or that are subject to repurchase agreements that call for
      delivery in twelve months or less. The Board of Trustees has proposed a
      change to this policy to increase the length of permitted maturity to up
      to the maximum time permitted under Rule 2a-7, which is currently 397
      days.  Please see "What Standards Apply to the Trust's Investment?"
      below for more details.

o     Other  Money  Market  Obligations.  The Trust may  invest in money  market
      obligations  other  than  those  listed  above  if  they  are  subject  to
      repurchase  agreements or guaranteed as to their principal and interest by
      a corporation whose commercial paper may be purchased by the Trust or by a
      domestic  bank.  The bank must meet  credit  criteria  set by the  Trust's
      Board.

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

      Currently,  the Board has  approved  the  purchase  of  dollar-denominated
obligations of foreign banks payable in the U.S. or in London, England, floating
or  variable  rate  demand  notes,   asset-backed  securities,   and  bank  loan
participation agreements.  Their purchase may be subject to restrictions adopted
by the Board from time to time.

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
      Investment  Company Act for money market funds and  procedures  adopted by
      the Board.  The 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. The Trust's  fundamental policy restricting  investments
      in any debt  instrument  having a maturity  in excess of one year from the
      date of the investment is more  restrictive  than the standards that apply
      to all money  market  funds.  That  restriction  could  limit the  Trust's
      investments,  however,  shareholders  have been  requested  to  approve an
      amendment to this policy  whereby no  security's  maturity will exceed the
      maximum time  permitted  under Rule 2a-7. If the change is not approved by
      shareholders,  the Manager will supplement this Prospectus to reflect that
      the  change  was  not  approved.   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 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.  Please  see the
      Statement of Additional  Information for more information on the proposals
      to  change  the  fundamental  policies  that  the  Board of  Trustees  has
      requested  shareholders  to approve.  If  shareholders  do not approve the
      changes, then this Prospectus and Statement of Additional Information will
      be supplemented to advise you that the amendments were not approved.

OTHER  INVESTMENT  STRATEGIES.  To seek its  objective,  the  Trust  can use the
investment techniques and strategies described below. The Trust might not always
use all of them.  These  techniques  involve 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 (or
      if the  proposed  change is approved  by  shareholders,  the maximum  time
      permitted  under Rule 2a-7),  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 (or if the
      proposed  change is approved by  shareholders,  the maximum time permitted
      under Rule 2a-7).

Asset-Backed Securities. The Trust can invest in asset-backed investments. These
      are  fractional  interests  in pools of  consumer  loans and  other  trade
      receivables,  which are the obligations of a number of different  parties.
      The income from the underlying  pool is passed through to investors,  such
      as the Trust.

      These  investments might be supported by a credit  enhancement,  such as a
letter of  credit,  a  guarantee  or a  preference  right.  However,  the credit
enhancement generally applies only to a fraction of the security's value. If the
issuer of the security has no security interest in the related collateral, there
is the risk that the Trust could lose money if the issuer defaults.

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.

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
      Trust may  invest up to 25% of its net  assets in  restricted  securities,
      subject to the 10% limit on illiquid securities and restricted  securities
      other than those sold 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.

How the Trust is Managed

THE  MANAGER.   The  Manager,   Centennial  Asset  Management   Corporation,   a
wholly-owned subsidiary of OppenheimerFunds, Inc., is the investment advisor for
the Trusts. The Manager chooses each of the Trust's  investments and handles its
day-to-day business.  The Manager carries out its duties subject to the policies
established  by the Trust's  Board of  Trustees,  under an  investment  advisory
agreement  with each  Trust  that  states the  Manager's  responsibilities.  The
agreement sets the fees the Trust pays to the Manager and describes the expenses
that the Trust is responsible to pay to conduct its business.

      The Manager has been an investment advisor since 1978. The Manager and its
affiliates  managed  investment  companies  and  other  assets of more than $130
billion as of September 30, 2000, and more than 5 million shareholder  accounts.
The Manager is located at 6803 South Tucson Way, Englewood, Colorado 80112.

Portfolio Managers.  Carol E. Wolf is the portfolio manager of the Trust.
      She is the person principally responsible for the day-to-day management
      of the Trust's portfolio.  Ms. Wolf has had this responsibility since
      July 1990.  Ms. Wolf is a Senior Vice President of OppenheimerFunds,
      Inc. and of the Trust, and she is an officer and portfolio manager of
      other funds for which OppenheimerFunds, Inc. or the Manager serves as
      investment advisor.

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: 0.500% of the first $250 million of net assets;
      0.475% of the next $250  million  of net  assets;  0.450% of the next $250
      million of net  assets;  0.425% of the next $250  million  of net  assets;
      0.400% of the next $250  million  of net  assets;  0.375% of the next $250
      million of net assets;  0.350% of the next $500 million of net assets; and
      0.325% of net assets in excess of $2  billion.  Furthermore,  the  Manager
      guarantees  that the  total  expenses  of the  Trust in any  fiscal  year,
      exclusive of taxes, interest and brokerage commissions,  and extraordinary
      expenses such as litigation costs, shall not exceed the lesser of (1) 1.5%
      of the average  annual net assets of the Trust up to $30 million and 1% of
      its  average  annual  net assets in excess of $30  million;  or (2) 25% of
      total annual  investment  income of the Trust. The Trust's  management fee
      for its fiscal year ended June 30,  2000 was 0.34% of the Trust's  average
      annual net assets.

How to Buy Shares

HOW ARE SHARES  PURCHASED?  You can buy shares  directly  through  your  dealer,
broker or  financial  institution  that has a sales  agreement  with the Trust's
Distributor.  The Distributor,  in its sole discretion,  may reject any purchase
order for the Trust's shares.

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

HOW ARE SHARES PURCHASED THROUGH AUTOMATIC PURCHASE AND REDEMPTION PROGRAMS?  If
you buy shares through your  broker-dealer's  Automatic  Purchase and Redemption
Program,  your  broker-dealer will buy your shares of the Trust 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.

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 a Trust.

AUTOMATIC PURCHASE AND REDEMPTION  PROGRAM. If you buy shares of a 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  Procedures" 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
Trusts'  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
      a 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 a Trust.

o     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.

o     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.

|X|   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 MUCH MUST YOU INVEST? You can open account with a minimum initial investment
of $10 million  and make  additional  investments  at any time with as little as
$500,000.  The  minimum  investment  requirement  does not apply to  reinvesting
dividends from the Trust.

HOW ARE SHARE PRICES DETERMINED? Shares of each 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 a 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.) receives the purchase order
at its offices in 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 a Trust's Net Asset Value Determined?  The net asset value of shares of
      each 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 a
Trust's net assets by the number of shares that are outstanding.  Under a policy
adopted by the Board of Trustees of the  Trusts,  each Trust uses the  amortized
cost method to value its securities to determine net asset value.

WHAT CLASSES OF SHARES DOES THE TRUST  OFFER?  The Trust  offers  investors  two
different  classes of shares.  One share class is designed for retail  investors
and another  share class is designed for certain  institutional  investors.  The
different  classes of shares  represent  investments  in the same  portfolio  of
securities,  but the classes are subject to  different  expenses and will likely
have different share prices.  The Trust's retail share class is are offered by a
separate  prospectus  dated November 1, 2000. Class Y shares are offered only to
certain   institutional   investors  who  have  special   agreements   with  the
Distributor.

WHO CAN BUY CLASS Y SHARES?  Class Y shares are sold at net asset value per
share without sales charge directly to certain institutional investors that
have special agreements with the Distributor for this purpose.  Individual
investors cannot buy Class Y shares directly.

      An  institutional  investor  that buys Class Y shares  for its  customers'
accounts  may impose  charges on those  accounts.  The  procedures  for  buying,
selling, exchanging and transferring the Trust's other classes of shares and the
special account  features  available to investors  buying those other classes of
shares do not  apply to Class Y  shares.  An  exception  is that the time  those
orders  must be  received by the  Distributor  or its agents or by the  Transfer
Agent is the same for Class Y as for the retail share class.  Those instructions
must be submitted by the institutional  investor, not by its customers for whose
benefit the share are held.

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.

If you participate in an Automatic  Purchase and Redemption Program sponsored by
your  broker-dealer,  you may  redeem  shares  held in your  Program  Account by
contacting  your  broker  or  dealer.   You  may  also  arrange  for  "Expedited
Redemptions"  as  described  below  through  your broker or dealer.  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 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 a Fund account with a different owner or
      name
o     Shares are being redeemed by someone (such as an Executor) other than
      the owners

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

Sending Redemption  Proceeds by Wire.  While the Trust normally sends your 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 your account or
      to arrange a wire, call the Transfer Agent at 1-800-525-9310.

HOW DO I SELL SHARES BY MAIL?  Write a "letter of instructions" that includes:
o     Your name
o     The Trust's name
o     Your Trust account number (from your account statement)
o     The dollar amount or number of shares to be redeemed
o     Any special payment instructions
o     Any share certificates for the shares you are selling
o     The signatures of all registered owners exactly as the account is
      registered, and
o     Any special  documents  requested by the Transfer  Agent to assure  proper
      authorization of the person asking to sell the shares.

HOW DO I SELL SHARES BY TELEPHONE?  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 by telephone.  To
redeem shares through a service representative, call 1-800-852-8457. Proceeds of
telephone  redemptions  will be paid by check 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.  The check must be payable to
all  owners of  record  of the  shares  and must be sent to the  address  on the
account statement.  This service is not available within 30 days of changing the
address on an account.

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

WILL I PAY A SALES CHARGE WHEN I SELL MY SHARES? The Trust does not charge a fee
when you redeem  Class Y shares of this Trust  that you  bought  directly  or by
reinvesting dividends or distributions from the Trust.

Shareholder Account Rules and Policies

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

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

Telephone Transaction  Privileges for purchases and redemptions 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  and has adopted other  procedures to confirm that  telephone
      instructions   are   genuine,   by   requiring   callers  to  provide  tax
      identification  numbers and other  account  data or by using PINs,  and by
      confirming such transactions in writing.  The Transfer Agent and the 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.

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

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  processing 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.

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 1-800-525-7048 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 on a date  selected  by the Board of  Trustees.  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,  it could  realize  capital gains on the sale of portfolio
      securities.  If it  does,  it  may  make  distributions  out  of  any  net
      short-term or long-term  capital gains in December of each year. The Trust
      may  make  supplemental  distributions  of  dividends  and  capital  gains
      following the end of its fiscal year.

      If  you  participate  in an  Automatic  Purchase  and  Redemption  Program
sponsored by your broker-dealer,  all dividends will be automatically reinvested
in additional shares of the Trust. Under the terms of the Automatic Purchase and
Redemption  Program,  your  broker-dealer can pay redeem shares to satisfy debit
balances arising in your Program Account.  If that occurs,  you will be entitled
to  dividends  on  those  shares  only  up to and  including  the  date  of such
redemption.

TAXES.  If your shares are not held in a tax-deferred  retirement  account,  you
should be aware of the  following  tax  implications  of investing in the Trust.
Dividends  paid from net  investment  income and  short-term  capital  gains are
taxable as ordinary  income.  Long-term  capital  gains are taxable as long-term
capital gains when  distributed to  shareholders  Trust.  It does not matter how
long you have held your  shares.  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 each  taxable  distribution  you received in the  previous  year.  Any
long-term capital gains  distributions will be separately  identified in the tax
information the Trust sends you after the end of the calendar year.

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  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.

Financial Highlights


The Financial  Highlights  Table is presented to help you understand the Trust's
financial  performance for the past 5 fiscal years ended June 30, 2000.  Class Y
shares have not been offered  during the past 5 fiscal years.  Accordingly,  the
information  shown is for the Trust's retail class of shares and not for Class Y
shares. Certain information reflects financial results for a single Trust share.
The total returns in the table  represent  the rate that an investor  would have
earned [or lost] on an investment  in the Trust  (assuming  reinvestment  of all
dividends and distributions). This information for the past 5 fiscal years ended
June 30, 2000 has been audited by Deloitte & Touche LLP, the Trust's independent
auditors, whose report, along with the Trust's financial statements, is included
in the Statement of Additional Information, which is available on request.

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,
(referred  to  as,  the  "Manager")  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's  objective  is to seek the  maximum  current  income  that is
consistent  with low capital risk and the  maintenance  of liquidity.  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.

      |X|  Ratings  of   Securities   --   Portfolio   Quality,   Maturity   and
Diversification.  Under Rule 2a-7 of the Investment  Company Act 1940, 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 places  restrictions on a money
market fund's  investments.  Under that Rule,  the Trust may purchase only those
securities that the Manager,  under  Board-approved  procedures,  has determined
have minimal credit risks and are "Eligible Securities." The rating restrictions
described in the Prospectus and this Statement of Additional  Information do not
apply to banks in which the Trust's cash is kept.

      An  "Eligible  Security"  is one  that  has  been  rated in one of the two
highest   short-term  rating   categories  by  any  two   "nationally-recognized
statistical  rating  organizations."  That term is defined in Rule 2a-7 and they
are  referred  to as "Rating  Organizations"  in this  Statement  of  Additional
Information.  If only one Rating  Organization has rated that security,  it must
have been  rated in one of the two  highest  rating  categories  by that  Rating
Organization.  An  unrated  security  that is  judged  by the  Manager  to be of
comparable quality to Eligible Securities rated by Rating Organizations may also
be an "Eligible Security."

      Rule  2a-7  permits  the Trust to  purchase  any  number  of  "First  Tier
Securities."  These are Eligible  Securities that have been rated in the highest
rating  category  for  short-term  debt  obligations  by  at  least  two  Rating
Organizations.  If only one Rating Organization has rated a particular security,
it  must  have  been  rated  in the  highest  rating  category  by  that  Rating
Organization. Comparable unrated securities may also be First Tier Securities.

      Under Rule 2a-7, the Trust may invest only up to 5% of its total assets in
"Second Tier Securities." Those are Eligible Securities that are not "First Tier
Securities." In addition, the Trust may not invest more than:
      |_| 5% of its total assets in the securities of any one issuer (other than
      the U.S. government,  its agencies or  instrumentalities) or |_| 1% of its
      total  assets  or  $1  million  (whichever  is  greater)  in  Second  Tier
      Securities of any one issuer.

      Under  Rule  2a-7,  the Trust  must  maintain  a  dollar-weighted  average
portfolio  maturity  of not more than 90 days,  and the  maturity  of any single
portfolio  investment  may not  exceed one year from the date of  purchase.  The
Board of Trustees has  recommended  that  shareholders  approve  increasing  the
maximum  permitted  maturity  to the maximum  permitted  under Rule 2a-7 (or any
other  applicable  rule)  which is  currently  397 days.  If that  change is not
approved by  shareholders,  the  prospectus  and this  Statement  of  Additional
Information  will be  supplemented  to reflect that the change was not approved.
The Board  regularly  reviews  reports  from the  Manager to show the  Manager's
compliance with the Trust's procedures and with the Rule.

      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.

      The Rating  Organizations  currently  designated as  nationally-recognized
statistical rating  organizations by the Securities and Exchange  Commission are
Standard & Poor's Corporation,  Moody's Investors Service, Inc., Fitch, Inc. and
Thomson BankWatch,  Inc. Appendix A to this Statement of Additional  Information
contains  descriptions of the rating  categories of those Rating  Organizations.
Ratings  at the  time of  purchase  will  determine  whether  securities  may be
acquired under the restrictions described above.

      |X| Bank  Obligations.  The  Trust  can  invest  in the  bank  obligations
described in the  Prospectus.  The Trust will buy bank  obligations  only from a
domestic  bank with total assets of at least $2.0 billion or from a foreign bank
with total assets of at least $30.0 billion. These asset requirements apply only
at the time the obligations are acquired.  In addition,  the Trust may invest in
certificates  of deposit of $100,000 or less of a domestic  bank,  regardless of
asset size, if such  certificate  of deposit is fully insured as to principal by
the Federal Deposit Insurance  Corporation.  At no time will the Trust hold more
than one certificate of deposit from any such bank

      Investments in securities  issued by foreign banks or foreign  branches of
U.S. banks subject the Trust to certain additional  investment risks,  including
future political and economic developments of the country in which the branch is
located,  possible  imposition  of  withholding  taxes on income  payable on the
securities,  possible  seizure of foreign  deposits,  establishment  of exchange
control restrictions,  or other government regulation.  While domestic banks are
subject to federal and/or state laws and regulations  which, among other things,
require  specific  levels of  reserves to be  maintained,  not all of those laws
apply to foreign branches of domestic banks or domestic branches or subsidiaries
of foreign  banks.  For  purposes  of this  section,  the term  "bank"  includes
commercial banks, savings banks and savings and loan associations.

      |X|  U.S.  Government   Securities.   U.S.   government   securities  are
obligations  issued or  guaranteed  by the U.S.  government  or its agencies or
instrumentalities.  They include  Treasury  Bills (which mature within one year
of the date they are issued)  and  Treasury  Notes and Bonds  (which are issued
with  longer  maturities).  All  Treasury  securities  are  backed  by the full
faith and credit of the United States.

      U.S.  government  agencies and  instrumentalities  that issue or guarantee
securities include, but are not limited to, the Federal Housing  Administration,
Farmers Home  Administration,  Export-Import  Bank of the United  States,  Small
Business  Administration,  Government  National  Mortgage  Association,  General
Services Administration, Bank for Cooperatives, Federal Home Loan Banks, Federal
Home Loan Mortgage Corporation,  Federal Intermediate Credit Banks, Federal Land
Banks, Maritime Administration,  the Tennessee Valley Authority and the District
of Columbia Armory Board.

      Securities   issued  or  guaranteed  by  U.S.   government   agencies  and
instrumentalities  are not  always  backed by the full  faith and  credit of the
United States.  Some, such as securities issued by the Federal National Mortgage
Association   ("Fannie  Mae"),  are  backed  by  the  right  of  the  agency  or
instrumentality to borrow from the Treasury.  Others,  such as securities issued
by the Federal Home Loan Mortgage  Corporation  ("Freddie  Mac"),  are supported
only  by the  credit  of the  instrumentality  and not by the  Treasury.  If the
securities are not backed by the full faith and credit of the United States, the
purchaser  must look  principally  to the  agency  issuing  the  obligation  for
repayment and may not be able to assert a claim against the United States if the
issuing agency or instrumentality  does not meet its commitment.  The Trust will
invest in U.S. government securities of such agencies and instrumentalities only
when the  Manager  is  satisfied  that the  credit  risk  with  respect  to such
instrumentality is minimal and that the security is an Eligible Security.

Other Investment Strategies

      O  Floating  Rate/Variable  Rate  Obligations.  The  Trust  may  invest in
instruments  with floating or variable  interest  rates.  The interest rate on a
floating rate obligation is based on a stated  prevailing market rate, such as a
bank's prime rate,  the 90-day U.S.  Treasury  Bill rate,  the rate of return on
commercial paper or bank  certificates of deposit,  or some other standard.  The
rate on the  investment is adjusted  automatically  each time the market rate is
adjusted.  The interest  rate on a variable  rate  obligation is also based on a
stated  prevailing  market  rate but is  adjusted  automatically  at a specified
interval  of not  less  than one  year.  Some  variable  rate or  floating  rate
obligations  in which the Trust may invest have a demand  feature  entitling the
holder to demand payment of an amount  approximately equal to the amortized cost
of the  instrument  or the  principal  amount  of the  instrument  plus  accrued
interest at any time, or at specified  intervals  not exceeding one year.  These
notes may or may not be backed by bank letters of credit.

      Variable  rate demand notes may include  master  demand  notes,  which are
obligations that permit the Trust to invest  fluctuating  amounts in a note. The
amount may change daily without penalty, pursuant to direct arrangements between
the Trust, as the note purchaser, and the issuer of the note. The interest rates
on  these  notes  fluctuate  from  time to  time.  The  issuer  of this  type of
obligation normally has a corresponding  right in its discretion,  after a given
period,  to prepay  the  outstanding  principal  amount of the  obligation  plus
accrued interest. The issuer must give a specified number of days' notice to the
holders of those  obligations.  Generally,  the changes in the interest  rate on
those securities reduce the fluctuation in their market value. As interest rates
decrease or increase,  the potential for capital appreciation or depreciation is
less than that for fixed-rate obligations having the same maturity.

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

      |X|  Asset-Backed  Securities.  These  securities,  issued by  trusts  and
special purpose  corporations,  are backed by pools of assets. They pass through
the  payments  on the  underlying  obligations  to the  security  holders  (less
servicing fees paid to the originator or fees for any credit  enhancement).  The
value of an  asset-backed  security  is  affected  by  changes  in the  market's
perception  of the asset  backing  the  security,  the  creditworthiness  of the
servicing agent for the loan pool, the originator of the loans, or the financial
institution providing any credit enhancement.

      Payments  of  principal  and  interest   passed   through  to  holders  of
asset-backed   securities  are  typically  supported  by  some  form  of  credit
enhancement,  such as a letter of credit,  surety  bond,  limited  guarantee  by
another  entity  or  having  a  priority  to  certain  of the  borrower's  other
securities.  The degree of credit  enhancement  varies, and generally applies to
only a fraction of the asset-backed security's par value until exhausted. If the
credit  enhancement  of an  asset-backed  security  held by the  Trust  has been
exhausted,  and if any required  payments of principal and interest are not made
with respect to the underlying  loans, the Trust may experience losses or delays
in receiving payment.
      The risks of investing in asset-backed securities are ultimately dependent
upon payment of underlying  assets. As a purchaser of an asset-backed  security,
the Trust would  generally  have no recourse to the entity that  originated  the
loans in the event of default by a borrower. The underlying loans are subject to
prepayments,  which shorten the weighted average life of asset-backed securities
and may lower their return,  in the same manner as for  prepayments of a pool of
mortgage loans  underlying  mortgage-backed  securities.  However,  asset-backed
securities  do not  have  the  benefit  of the  same  security  interest  in the
underlying collateral as do mortgage-backed securities.

      |X| Repurchase Agreements. In a repurchase transaction, the Trust acquires
a  security  from,  and  simultaneously  resells it to, an  approved  vendor for
delivery on an  agreed-upon  future date.  The resale price exceeds the purchase
price by an amount that reflects an agreed-upon  interest rate effective for the
period during which the repurchase  agreement is in effect. An "approved vendor"
may be 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
$50 million which has been designated a primary dealer in government securities.

      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.  The Trust will not enter into a repurchase  agreement that will cause
more than 10% of its net assets to be subject to repurchase  agreements maturing
in more than seven days.

      Repurchase  agreements are considered "loans" under 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  collateral's  value 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.  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.

      |X| Illiquid and Restricted Securities.  Under the policies and procedures
established  by the  Trust's  Board of  Trustees,  the  Manager  determines  the
liquidity  of certain of the Trust's  investments.  Investments  may be illiquid
because of the absence of an active trading market, making it difficult to value
them or dispose of them promptly at an acceptable  price. A restricted  security
is one that has a contractual  restriction on its resale or which cannot be sold
publicly until it is registered under the Securities Act of 1933.

      Illiquid  securities the Trust can buy include issues that may be redeemed
only by the issuer upon more than seven days notice or at  maturity,  repurchase
agreements  maturing in more than seven  days,  fixed time  deposits  subject to
withdrawal  penalties which mature in more than seven days, and other securities
that cannot be sold freely due to legal or contractual  restrictions  on resale.
Contractual  restrictions on the resale of illiquid  securities might prevent or
delay their sale by the Trust at a time when such sale would be desirable.

      There are restricted  securities  that are not illiquid that the Trust can
buy.  They  include  certain  master  demand  notes  redeemable  on demand,  and
short-term  corporate debt instruments that are related to current  transactions
of the issuer and therefore are exempt from  registration  as commercial  paper.
Illiquid securities include repurchase  agreements maturing in more than 7 days,
or certain participation interests other than those with puts exercisable within
7 days.

O Loans of Portfolio  Securities.  To attempt to increase its income,  the Trust
may lend its  portfolio  securities  to  brokers,  dealers  and other  financial
institutions.  These  loans are limited to not more than 10% of the value of the
Trust's total assets and are subject to other  conditions  described  below. The
Trust will not enter into any securities lending agreements having a maturity of
greater  than one year (or if the proposed  change is approved by  shareholders,
the maximum time permitted under Rule 2a-7). The Trust presently does not intend
to lend its  securities,  but if it does, the value of securities  loaned is not
expected to exceed 5% of the value of the Trust's total  assets.  There are some
risks in lending  securities.  The Trust could  experience  a delay in receiving
additional  collateral  to secure a loan,  or a delay in  recovering  the loaned
securities.

      The Trust may receive  collateral for a loan.  Any securities  received as
collateral  for a loan  must  mature in twelve  months  or less.  Under  current
applicable  regulatory  requirements  (which  are  subject to  change),  on each
business day the loan  collateral  must be at least equal to the market value of
the loaned  securities.  The  collateral  must consist of cash,  bank letters of
credit, U.S. government  securities 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. Such terms and the issuing bank must be satisfactory to the
Trust.

      When it lends  securities,  the Trust receives from the borrower an amount
equal to the interest  paid or the dividends  declared on the loaned  securities
during the term of the loan.  It may also receive  negotiated  loan fees and the
interest  on  the   collateral   securities,   less  any  finders',   custodian,
administrative  or other fees the Trust pays in  connection  with the loan.  The
Trust may share the interest it receives on the collateral  securities  with the
borrower as long as it realizes at least a minimum  amount of interest  required
by the lending guidelines established by its Board of Trustees.
      The Trust will not lend its portfolio securities to any officer,  Trustee,
employee  or  affiliate  of the Trust or its  Manager.  The terms of the Trust's
loans must meet  certain  tests under the  Internal  Revenue Code and permit the
Trust to reacquire loaned  securities on five business days notice or in time to
vote on any important matter.

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.

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

      |_|  The  Trust  cannot  invest  more  than 5% of the  value of its total
assets in the  securities of any one issuer (other than the U.S.  government or
its agencies or instrumentalities).

      |_| The Trust  cannot  borrow  money  except as a  temporary  measure  for
extraordinary or emergency purposes, and then only up to 10% of the market value
of the  Trust's  assets;  the  Trust  will  not make any  investment  when  such
borrowing  exceeds 5% of the value of its assets;  no assets of the Trust may be
pledged, mortgaged or assigned to secure a debt.

      |_| The Trust cannot make loans,  except the Trust may: (i) purchase  debt
securities,  (ii) purchase debt securities subject to repurchase agreements,  or
(iii)  lend  its  securities  as  described  in  this  Statement  of  Additional
Information.

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

      |_| The Trust cannot invest in real estate; however the Trust may purchase
debt  securities  issued by  companies  which invest in real estate or interests
therein.

      |_| The Trust cannot purchase  securities on margin or make short sales of
securities.

      |_| The Trust cannot  invest in or hold  securities of any issuer if those
officers  and  Trustees  of  the  Trust  or the  Manager  who  beneficially  own
individually  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 in connection with a consolidation or merger.

      |_| 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.

     The Board of Trustees has recommended that shareholders approve changing or
eliminating  certain  fundamental  policies  of the  Trust.  These  changes  are
expected to be approved by  shareholders  at a meeting  which is scheduled to be
held on or about December 15, 2000 (or any adjournments of that meeting). If the
changes are not  approved by  shareholders,  the Manager  will  supplement  this
Statement  of  Additional  Information  to  reflect  that the  changes  were not
approved.  The changes to  fundamental  policies  that the Board of Trustees has
recommended that shareholders approve are as follows:

?     Eliminating certain fundamental investment restrictions.

A.    Eliminating the fundamental investment restriction that limits investments
      in  securities  of  unseasoned  issuers.   Specifically,   the  Board  has
      recommended  that  shareholders  approve the  elimination of the following
      fundamental investment restriction:

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

B.    Eliminating the fundamental  investment restriction concerning the Trust's
      purchase of more than 10% of non-voting securities or more than 10% of the
      total  debt  securities  of any one  issuer.  Specifically,  the Board has
      recommended  that  shareholders  approve the  elimination of the following
      fundamental investment restriction:

---------------------------------------------------------------------
Current
---------------------------------------------------------------------
---------------------------------------------------------------------
The  Trust  cannot   purchase  more  than  10%  of  the  outstanding
non-voting  securities or more than 10% of the total debt securities
of any one issuer.
---------------------------------------------------------------------

?     Approving   amendments   to   certain   fundamental   investment
restrictions.

A.    Amending  the  fundamental  investment  restriction  on  investing in debt
      securities  having a maturity  greater than one year. The Trust  currently
      has a fundamental  investment restriction that limits the maturity on debt
      securities it can purchase to one year or less.  This  restriction is more
      restrictive than is required under Rule 2a-7.  Accordingly,  the Board has
      recommended that shareholders approve the following change:

---------------------------------------------------------------------
Current                            Proposed
---------------------------------------------------------------------
---------------------------------------------------------------------
The Trust cannot  invest in any The Trust cannot  invest in any debt  instrument

maturity in excess of the time date of the investment or, in the period provided
for in Rule 2a-7 case of a debt instrument subject of the Investment Company Act
of to a  repurchase  agreement  or 1940,  or any  other  applicable  called  for
redemption,  having a rule,  or in the case of a debt  repurchase  or redemption
date  instrument  subject  to a more  than  one year  from  the date  repurchase
agreement or called of the investment. for redemption, unless purchased

                                   which  may not  exceed  the  time
                                   period provided for in Rule 2a-7
---------------------------------------------------------------------

B.    Amending the Trust's  concentration  policy.  The Securities and Exchange
Commission
      as  requested  that  the  Trust's  concentration  policy  be  amended  to
      prohibit the purchase of  securities  of companies in any one industry if
      "25% or  more  of its  total  assets"  would  consist  of  securities  of
      companies  in that  industry,  (rather  than  "more than 25% of its total
      assets").  Accordingly,  the  Board  has  recommended  that  shareholders
      approve the following change:
---------------------------------------------------------------------
Current                            Proposed
---------------------------------------------------------------------
---------------------------------------------------------------------
The Trust cannot concentrate to The Trust cannot invest 25% or the extent of 25%

single industry.
---------------------------------------------------------------------

      These proposed changes are described in more detail in the Proxy Statement
which was previously sent to shareholders. If you have any questions about these
changes, please contact the Transfer Agent at 1.800.525.9310.

      Except for the fundamental  investment  restriction  regarding the Trust's
borrowing  policy,  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,  diversified  management
investment company organized as a Massachusetts  business trust in 1979, 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 Board of  Trustees  has the  power,  without
shareholder  approval,  to divide  unissued shares of the Trust into two or more
classes.  The Board has done so,  and the Trust  currently  has  authorized  the
issuance of two classes of shares.  The class of shares currently offered by the
Prospectus  and this  Statement of  Additional  information  has no special name
designation.  The Trust's other class of shares, designated as "Class Y" shares,
is not currently available.  At such time as Class Y shares are available,  both
classes  of shares  will  invest in the same  investment  portfolio.  Shares are
freely  transferable.  Each  share has one vote at  shareholder  meetings,  with
fractional  shares  voting  proportionally  on matters  submitted to the vote of
shareholders. Each class of shares:

      |_|            has its own dividends and distributions,
      |_|             pays  certain  expenses  which may be  different  for the
   different classes,
      |_|             may have a different net asset value,
|_|   may have separate  voting rights on matters in which the interests of one
        class are different from the interests of another class, and
      |_|             votes  as a class  on  matters  that  affect  that  class
alone.

      |X| Meetings of Shareholders. As a 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.

  Ned M. Steel2            $7,230          $67,998

  ------------------------------------------------------------------
1.    For the 1999 calendar year.
2.    Effective  July 1, 2000,  Messrs.  Baker and Steel resigned as Trustees of
      the Trust.

      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  10,  2000  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.  1  North  Jefferson  Avenue,  St.  Louis,  Missouri  63103,  which  owned
19,505,155,245.27  shares  of the  Trust  which  was  99.6% 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,   Centennial  Asset  Management   Corporation,   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  managers of the Trust are  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.

----------------------------------------------------------------------
     2000                           $62,139,589
----------------------------------------------------------------------

      Under  the  investment  advisory  agreement,  the  Manager  has  agreed to
reimburse the Trust to the extent that the Trust's total expenses (including the
management  fee  but  excluding  interest,  taxes,  brokerage  commissions,  and
extraordinary  expenses such as litigation  costs) exceed in any fiscal year the
lesser of: (i) 1.5% of average  annual net assets of the Trust up to $30 million
plus 1% of the  average  annual net assets in excess of $30 million or; (ii) 25%
of the total annual  investment income of the Trust. For fiscal years ended June
30, 1998, June 30, 1999 and June 30, 2000, the  reimbursements by the Manager to
the Trust were $2,382,437, $0, and $0, respectively.

    The  investment  advisory  agreement  provides that the Manager shall not be
liable for any loss sustained by reason of the adoption of an investment  policy
or the  purchase,  sale or  retention  of any  security  on its  recommendation,
whether  or  not  such  recommendation  shall  have  been  based  upon  its  own
investigation and research or upon  investigation and research made by any other
individual, firm or corporation, if such recommendation shall have been made and
such other  individual,  firm or  corporation  shall have been selected with due
care  and in good  faith,  provided  that  nothing  in the  agreement  shall  be
construed  to protect the  Manager  against  any  liability  to the Trust or its
shareholders by reason of willful misfeasance,  bad faith or gross negligence in
the  performance  of its duties,  or by reason of its reckless  disregard of its
obligations and 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.   The   Trust's   Sub-Distributor   is
OppenheimerFunds Distributors, Inc.

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 may  experience  high  portfolio  turnover that 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.

      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, 2000  payments  under the plan  totaled
$36,929,811,  all of  which  was paid by the  Distributor  to  recipients.  That
included $1,208 paid to an affiliate of the  Distributor's  parent company.  For
the  fiscal  year ended June 30,  2000,  the  Manager  paid,  in the  aggregate,
$54,937,351 in fees out of its own resources for  distribution  assistance.  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" 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.

          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,  Washington's  Birthday,  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

Distributions   From  Retirement   Plans.   Requests  for   distributions   from
OppenheimerFunds-sponsored  IRAs,  403(b)(7)  custodial  plans,  401(k) plans or
pension   or   profit-sharing   plans   should   be   addressed   to   "Trustee,
OppenheimerFunds Retirement Plans," c/o the Transfer Agent at its address listed
in "How To Sell Shares" in the Prospectus or on the back cover of this Statement
of Additional Information. The request must

(1)   state the reason for the distribution;
(2)   state the owner's  awareness  of tax  penalties  if the  distribution  is
        premature; and
(3)     conform to the requirements of the plan and the Trust's other redemption
        requirements.

      Participants      (other      than      self-employed      persons)     in
OppenheimerFunds-sponsored  pension or  profit-sharing  plans with shares of the
Trust held in the name of the plan or its  fiduciary  may not  directly  request
redemption of their accounts.  The plan administrator or fiduciary must sign the
request.

      Distributions from pension and profit sharing plans are subject to special
requirements  under the Internal Revenue Code and certain  documents  (available
from the Transfer  Agent) must be completed and submitted to the Transfer  Agent
before the  distribution  may be made.  Distributions  from retirement plans are
subject to  withholding  requirements  under the Internal  Revenue Code, and IRS
Form W-4P  (available from the Transfer Agent) must be submitted to the Transfer
Agent with the distribution request, or the distribution may be delayed.  Unless
the   shareholder   has  provided  the  Transfer  Agent  with  a  certified  tax
identification  number,  the Internal Revenue Code requires that tax be withheld
from any distribution  even if the shareholder  elects not to have tax withheld.
The Trust, the Manager,  the Distributor the  Sub-Distributor,  and the Transfer
Agent assume no responsibility to determine whether a distribution satisfies the
conditions  of  applicable  tax laws and  will  not be  responsible  for any tax
penalties assessed in connection with a distribution.

      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 federal tax treatment
of the Trust's  dividends  and capital gains  distributions  is explained in the
Prospectus  under the  caption  "Distributions  and Taxes."  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. It if 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 Board of Trustees and the
Manager  might  determine  in a  particular  year  that it  would be in the best
interest of shareholders for the Trust 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.   The   Trust's   dividends   will   not  be   eligible   for  the
dividends-received deduction for corporations.

      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  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 distributions made to shareholders.

      Dividends,  distributions  and the  proceeds  of the  redemption  of Trust
shares  represented  by checks  returned  to the  Transfer  Agent by the  Postal
Service as undeliverable  will be invested in shares of the Trust as promptly as
possible  after the return of such  checks to the  Transfer  Agent,  in order to
enable the investor to earn a return on otherwise idle funds.

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
OppenheimerFunds,  Inc. and for certain  other funds advised by the Manager and
its affiliates.

Independent Auditors' Report

Centennial Money Market Trust

To the Board of Trustees and Shareholders of Centennial Money Market Trust:

We have  audited  the  accompanying  statement  of  assets  and  liabilities  of
Centennial  Money Market Trust,  including the statement of  investments,  as of
June 30, 2000, and the related  statement of operations for the year then ended,
the  statements of changes in net assets for each of the two years in the period
then  ended,  and the  financial  highlights  for each of the five  years in the
period then ended. 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 auditing standards generally accepted
in the  United  States of  America.  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, 2000, 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,  the financial  statements and financial  highlights referred to
above  present  fairly,  in all material  respects,  the  financial  position of
Centennial Money Market Trust as of June 30, 2000, the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period  then ended,  and the  financial  highlights  for each of the five
years in the  period  then  ended,  in  conformity  with  accounting  principles
generally accepted in the United States of America.

Centennial Money Market Trust

1. Significant Accounting Policies

Centennial  Money Market Trust (the Trust) is  registered  under the  Investment
Company  Act  of  1940,  as  amended,  as  a  diversified,  open-end  management
investment  company.  The Trust's  investment  objective  is to seek the maximum
current income that is consistent  with low capital risk and the  maintenance of
liquidity.  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.

Repurchase Agreements.  The Trust requires the custodian to take possession,  to
have  legally  segregated  in the Federal  Reserve  Book Entry System or to have
segregated  within the custodian's  vault, all securities held as collateral for
repurchase agreements. The market value of the underlying securities is required
to be at least 102% of the resale price at the time of  purchase.  If the seller
of the agreement  defaults and the value of the collateral  declines,  or if the
seller  enters  an  insolvency  proceeding,  realization  of  the  value  of the
collateral by the Trust may be delayed or limited.

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.

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

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.

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. Fees and Other Transactions with Affiliates

Management Fees. 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 the Trust's  net  assets,  0.475% of the next $250
million, 0.45% of the next $250 million,  0.425% of the next $250 million, 0.40%
of the next $250  million,  0.375% of the next $250  million,  0.35% of the next
$500  million and 0.325% of net assets in excess of $2 billion.  The Manager has
agreed to reimburse the Trust if aggregate expenses (with specified  exceptions)
exceed the  lesser of 1.50% of average  annual net assets of the Trust up to $30
million,  and 1% of its average  annual net assets in excess of $30 million;  or
25% of the total annual investment  income of the Trust. The Trust's  management
fee for the year ended June 30, 2000 was an annualized rate of 0.34%, before any
waiver by the Manager if applicable.

Transfer Agent Fees. Shareholder Services, Inc. (SSI) acts as the transfer and
shareholder servicing agent for the Trust and for other registered investment
companies on an "at-cost" basis.

Service Plan Fees.  Under an approved  service plan,  the Trust may expend up to
0.20% of its average  annual 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 financial institutions.  During the year ended
June 30,  2000,  the Trust paid $1,208 to a  broker/dealer  affiliated  with the
Manager as reimbursement for distribution-related expenses.

                              RATINGS DEFINITIONS

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

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

Long-Term (Taxable) Bond Ratings

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

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

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

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

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

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

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

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

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

Con. (...):  Bonds for which the security  depends on the completion of some act
or the  fulfillment of some condition are rated  conditionally.  These bonds are
secured by (a) earnings of projects under construction, (b) earnings of projects
unseasoned in operating  experience,  (c) rentals that begin when facilities are
completed,  or (d) payments to which some other limiting condition attaches. The
parenthetical   rating  denotes  probable  credit  stature  upon  completion  of
construction or elimination of the basis of the condition.

Moody's  applies  numerical  modifiers  1,  2,  and  3 in  each  generic  rating
classification  from "Aa" through  "Caa." The modifier  "1"  indicates  that the
obligation ranks in the higher end of its generic rating category;  the modifier
"2" indicates a mid-range  ranking;  and the modifier "3" indicates a ranking in
the lower end of that generic rating category. Advanced refunded issues that are
secured by certain assets are identified with a # symbol.

Short-Term Ratings - Taxable Debt

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

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

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

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

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


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

Long-Term Credit Ratings

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

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

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

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

BB, B, CCC, CC, and C

Bonds rated "BB",  "B", "CCC",  "CC" and "C" are regarded as having  significant
speculative characteristics. "BB" indicates the least degree of speculation, and
"C" the  highest.  While such  obligations  will  likely  have some  quality and
protective  characteristics,  these may be outweighed by large  uncertainties or
major exposures to adverse conditions.  BB: Bonds rated "BB" are less vulnerable
to nonpayment than other speculative issues.  However,  these face major ongoing
uncertainties or exposure to adverse business, financial, or economic conditions
which could lead to the  obligor's  inadequate  capacity  to meet its  financial
commitment on the obligation.

B: Bonds rated "B" are more  vulnerable to  nonpayment  than  obligations  rated
"BB",  but  the  obligor  currently  has the  capacity  to  meet  its  financial
commitment  on  the  obligation.   Adverse  business,   financial,  or  economic
conditions will likely impair the obligor's  capacity or willingness to meet its
financial commitment on the obligation.

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

CC:  Bonds rated "CC" are currently highly vulnerable to nonpayment.

C: A  subordinated  debt or preferred  stock  obligation  rated "C" is currently
highly vulnerable to nonpayment. The "C" rating may be used to cover a situation
where a bankruptcy petition has been filed or similar action has been taken, but
payments on this obligation are being continued.  A "C" also will be assigned to
a preferred  stock issue in arrears on dividends or sinking fund  payments,  but
that is currently paying.

D: Bonds rated "D" are in default. Payments on the obligation are not being made
on the date due even if the  applicable  grace  period has not  expired,  unless
Standard and Poor's  believes  that such payments will be made during such grace
period.  The "D"  rating  will  also be used  upon the  filing  of a  bankruptcy
petition  or the taking of a similar  action if payments  on an  obligation  are
jeopardized.

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

-------------------------------------------------------------------------------
Short-Term Issue Credit Ratings
-------------------------------------------------------------------------------

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

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

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

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

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

D:  Obligation is in payment  default.  Payments on the obligation have not been
made on the due date even if the applicable grace period has not expired, unless
Standard and Poor's  believes  that such payments will be made during such grace
period.  The "D"  rating  will  also be used  upon the  filing  of a  bankruptcy
petition  or the taking of a similar  action if payments  on an  obligation  are
jeopardized.

International Long-Term Credit Ratings

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

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

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

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

Speculative Grade:

BB: Speculative. "BB" ratings indicate that there is a possibility of credit
risk developing, particularly as the result of adverse economic change over
time. However, business or financial alternatives may be available to allow
financial commitments to be met. Securities rated in this category are not
investment grade.

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

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

DDD, DD, and D: Default.  The ratings of  obligations in this category are based
on their prospects for achieving partial or full recovery in a reorganization or
liquidation  of  the  obligor.   While  expected   recovery  values  are  highly
speculative  and cannot be estimated with any precision,  the following serve as
general  guidelines.  "DDD" obligations have the highest potential for recovery,
around  90%-100% of  outstanding  amounts and accrued  interest.  "DD" indicates
potential  recoveries  in the  range of  50%-90%,  and "D" the  lowest  recovery
potential, i.e., below 50%.

Entities  rated  in  this  category  have  defaulted  on  some  or all of  their
obligations.  Entities  rated "DDD" have the highest  prospect for resumption of
performance  or  continued  operation  with or  without a formal  reorganization
process.  Entities  rated  "DD"  and  "D"  are  generally  undergoing  a  formal
reorganization or liquidation process;  those rated "DD" are likely to satisfy a
higher portion of their outstanding obligations, while entities rated "D" have a
poor prospect for repaying all obligations.  Plus (+) and minus (-) signs may be
appended to a rating  symbol to denote  relative  status within the major rating
categories.  Plus and minus  signs are not  added to the  "AAA"  category  or to
categories below "CCC," nor to short-term ratings other than "F1" (see below).

International Short-Term Credit Ratings

F1: Highest credit quality.  Strongest  capacity for timely payment of financial
commitments.  May have an added "+" to denote any  exceptionally  strong  credit
feature.

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

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

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

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

D:     Default. Denotes actual or imminent payment default.

None.

Item 25. - Indemnification

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

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