The Trust's Objective and Investment Strategies

WHAT IS THE  TRUST'S  INVESTMENT  OBJECTIVE?  The  Trust  seeks a high  level of
current  income  that is  consistent  with the  preservation  of capital and the
maintenance of liquidity.

WHAT DOES THE TRUST  INVEST IN?  The Trust is a money  market  fund.  It invests
principally in short-term debt instruments issued by the U.S. government.

WHO IS THE TRUST  DESIGNED FOR? The Trust may be  appropriate  for investors who
want to earn income at current money market rates while  preserving the value of
their investment, because the Trust is managed to keep its share price stable at
$1.00. The Trust does not invest for the purpose of seeking capital appreciation
or gains.

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 is a money  market fund that seeks  income by  investing  in
short-term debt  securities that must meet strict  standards set by its Board of
Trustees following rules for money market funds under federal law. These 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  diversifying  the  Trust's
investments  among  issuers to reduce the effects of a default by any one issuer
on 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. 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. As a result,  there is a risk that the Trust's  shares could
fall below $1.00 per share.

      An investment in the Trust is not a complete investment program.  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.

- --------------------------------------------------------------------------------
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  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 is not necessarily an
indication of how the Trust will perform in the future.

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

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

For the period from 1/1/99 through 9/30/99 the cumulative  total return was __%.

Fees and Expenses of the Trust

The Trust pays a variety of  expenses  directly  for  management  of its assets,
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.  Shareholders  pay other
expenses directly, such as account transaction charges. The following tables are
provided 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, 1999.

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

About the Trust's Investments

THE TRUST'S PRINCIPAL  INVESTMENT  POLICIES.  In seeking a high level of current
income that is consistent  with the  preservation of capital and the maintenance
of liquidity,  the Trust invests in short-term money market  securities  meeting
quality,  maturity and  diversification  standards  established for money market
funds under the Investment Company Act. The Statement of Additional  Information
contains more detailed  information  about the Trust's  investment  policies and
risks.

What Types of Money Market Securities Does the Trust Invest In? The following is
   a brief  description  of the types of money market  securities  the Trust may
   invest  in.  Money  market  instruments  are  high-quality,  short-term  debt
   instruments that may be issued by the U.S.  government,  domestic and foreign
   corporations,  banks or other  entities.  They may have  fixed,  variable  or
   floating interest rates.

   o  U.S. Government  Securities.  The Trust can invest in securities issued or
      guaranteed  by the U.S.  Treasury  or other U.S.  government  agencies  or
      instrumentalities,  maturing  in  twelve  months  or less from the date of
      purchase.  These are referred to as "U.S.  government  securities" in this
      Prospectus.

      1. U.S.  Treasury  Obligations.   These  include  Treasury  bills  (having
         maturities  of one year or less when  issued),  Treasury  notes (having
         maturities  of from one to ten years when issued),  and Treasury  bonds
         (having  maturities  of more  than ten  years  when  issued).  Treasury
         securities are backed by the full faith and credit of the United States
         as to timely payments of interest and repayments of principal. Although
         they are not rated by rating  organizations,  U.S. Treasury obligations
         are  considered to be of the highest credit quality with little risk of
         default.

     2.   Obligations of U.S.  Government Agencies or  Instrumentalities.  These
          include debt  obligations that have different levels of credit support
          from the U.S. government.  They can include obligations of agencies or
          instrumentalities  such as Government  National Mortgage  Association,
          Federal  Home  Loan  Bank,  Federal  Home Loan  Mortgage  Corporation,
          Student  Loan  Marketing  Association,  for  example.  Some  of  these
          obligations  are  supported  by the full  faith and credit of the U.S.
          government,  others are supported by the right of the issuer to borrow
          from the U.S. Treasury under certain  circumstances,  while others are
          supported  only  by  the  credit  of  the  entity  that  issued  them.
          Obligations  of  U.S.   government   agencies  and   instrumentalities
          generally have relatively little credit risk.

   o  Certain  Debt  Obligations.  The Trust may invest in variable  rate notes,
      variable rate master demand notes or in master demand notes. The Trust may
      also purchase debt  obligations  that mature within twelve months from the
      date of purchase.  It may purchase debt  obligations that have been called
      for redemption by the issuer if the redemption will occur within one year.

      Additionally,  the Trust may buy other money market  instruments  that its
Board  of   Trustees   approves   from   time  to  time.   They   must  be  U.S.
dollar-denominated  short-term investments that the Board must determine to have
minimal  credit  risks.  They also must be of "high  quality" as determined by a
national  rating  organization.  The  Trust  may buy an  unrated  security  that
otherwise meets those qualifications.

What Credit Quality and Maturity Standards Apply to the Trust's Investments? The
   Trust may buy only those  securities that meet credit  quality,  maturity and
   diversification  standards set in the Investment Company Act for money market
   funds. For example,  the Trust must maintain an average portfolio maturity of
   not more than 90 days. Some of the Trust's  investment  restrictions are more
   restrictive  than the  standards  that apply to all money market  funds.  For
   example,  as a matter of fundamental  policy, the Trust may not invest in any
   debt instrument  having a maturity in excess of one year from the date of the
   investment.  The  Board  of  Trustees  has  adopted  procedures  to  evaluate
   securities for the Trust's  portfolio  under those  standards and the Manager
   has  the   responsibility   to  implement  those  procedures  when  selecting
   investments for the Trust.

      In general, those procedures require that the Trust hold only money market
instruments  that  are  rated  in one  of  the  two  highest  short-term  rating
categories  of two  national  rating  organizations  or  unrated  securities  of
comparable  quality.  Under the procedures the Trust can invest without limit in
U.S. government securities because of their limited investment risks.

      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.

Canthe Trust's  Investment  Objective and Policies Change?  The Trust's Trustees
   can change  non-fundamental  policies without shareholder approval,  although
   significant  changes  will be  described in  amendments  to this  Prospectus.
   Fundamental policies are those that 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.  An investment  policy is not fundamental
   unless this Prospectus or the Statement of Additional Information says that a
   particular policy is fundamental.

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

Floating  Rate/Variable Rate Notes. Some of the notes the Trust may purchase may
   have variable or floating  interest  rates.  Variable rates are adjustable at
   stated  periodic  intervals  of no more  than one  year.  Floating  rates are
   automatically  adjusted  according  to  a  specified  market  rate  for  such
   investments,  such as the prime rate of a bank,  or the 90-day U.S.  Treasury
   bill rate. The Trust may purchase these  obligations if they have a remaining
   maturity of one year or less;  if their  maturity  is greater  than one year,
   they may be purchased if the Trust is able to recover the principal amount of
   the  underlying  security at specified  intervals  not exceeding one year and
   upon no more than 30 days' notice.  Such  obligations  may be secured by bank
   letters  of credit  or other  credit  support  arrangements  which  guarantee
   payment.

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 Trusts 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  maturing in seven
   days or less.

Illiquid and Restricted  Securities.  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.  Restricted  securities may
   have a contractual limit on resale or may require  registration under federal
   securities  laws before they can be sold publicly.  The Trust will not invest
   more than 10% of its net assets in illiquid securities,  including repurchase
   agreements of more than seven days' duration, securities which are restricted
   as to resale  and  other  securities  that are not  readily  marketable.  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.

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

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

     OppenheimerFunds, Inc. or the Manager serves as investment advisor. Michael
     Carbuto has been the portfolio manager of Centennial Tax Exempt Trust 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 adviser.

Advisory Fees. The  management  fee is payable  monthly to the Manager under the
   terms of each Trust's Investment Advisory Agreement.  That fee is computed on
   the average annual net assets of the respective Trust as of the close of each
   business day. See the Statement of Additional  Information for an explanation
   of the Manager's reimbursement  arrangement for the Trusts set forth in their
   Agreements.

      The annual  rates  applicable  to  Centennial  Money  Market  Trust are as
follows: 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,  and the
Manager  undertakes  to pay or  refund to the  Trust  any  amount by which  such
expenses  shall exceed,  the lesser of (i) 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 (ii) 25% of total annual investment income of the Trust. The
Trust's  management  fee for the fiscal year ended June 30, 1999 was ___% of the
Trust's average annual net assets.

      The annual rates applicable to Centennial Government Trust are as follows:
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;  and 0.400% of the next $250 million of net assets;
0.375% of the next $250 million of net assets and 0.350% of net assets in excess
of $1.5 billion.

      The annual rates applicable to Centennial Tax Exempt Trust are as follows:
0.500% of the first $250 million of net assets;  0.475% of the next $250 million
of net assets; 0.45% of the next $250 million of net assets;  0.425% of the next
$250  million of net  assets;  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,
under  Centennial  Tax Exempt  Trust's  Agreement,  when the value of Tax Exempt
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,  but in no event shall the annual fee be
less than $0.

How to Buy Shares

AT WHAT PRICE ARE SHARES SOLD?  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  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  Distributor
receives the  purchase  order at its offices in Denver,  Colorado,  or after any
agent  appointed  by the  Distributor  receives  the  order  and sends it to the
Distributor as described below.

HOW MUCH  MUST  YOU  INVEST?  You can open an  account  with a  minimum  initial
investment described below depending on how you buy and pay for your shares, and
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 Oppenheimer funds (a list of them appears in the Statement of
Additional  Information,  or you can ask your dealer or call the Transfer Agent)
or  reinvesting  distributions  from  unit  investment  trusts  that  have  made
arrangements with the Distributor.

HOW ARE SHARES PURCHASED?  Investors can buy shares in one of several ways:

      1. Buying  Shares  Through a Dealer's  Automatic  Purchase and  Redemption
         Program:  Investors can buy shares of a Trust  through a  broker-dealer
         that  has  a  sales   agreement   with  that  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.

      2. Buying Shares Through Your Dealer:  Investors who do not participate in
         an Automatic  Purchase and Redemption Program may buy shares of a Trust
         through  any  broker-dealer   that  has  a  sales  agreement  with  the
         Distributor or the  Sub-Distributor.  Your dealer will place your order
         with the Distributor on your behalf.

      3. Buying  Shares  Directly  Through the  Distributor:  Investors can also
         purchase shares directly through the Trusts' Distributor. Investors who
         make purchases directly and hold shares in their own names are referred
         to as "Direct Investors" in this Prospectus.

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

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 a 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 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 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.

      1. If the  Distributor  receives a purchase  order  before 12:00 Noon on a
         regular  business  day with the  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. (All references to time
         in this Prospectus mean "New York time.")  Distributions  will begin to
         accrue on the shares on that day if the Federal  Funds are  received by
         the required time.

      2. If the  Distributor  receives a purchase  order  after  12:00 Noon on a
         regular  business  day with the  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.

      3. 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  INVESTORS BUY SHARES THROUGH THE  DISTRIBUTOR?  Direct Investors
may buy  shares  of a  Trust  by  completing  a  Centennial  Funds  New  Account
Application  (enclosed  with  this  Prospectus),  along  with  the  three  other
documents  listed  above,  and  sending  them  to  Centennial  Asset  Management
Corporation,  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  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 Investors may pay for purchases of shares of a Trust by
   check. Send your check, payable to "Centennial Asset Management Corporation,"
   along with your  Application and other documents 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 Investors by check is $500.

Payment by Federal Funds Wire.  Direct Investors may pay for purchases of Shares
   of a Trust by Federal Funds wire. You must also forward your  Application and
   other documents to the address listed above.  Before sending a wire, call the
   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  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  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 Investors 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.

Howis a Trust's Net Asset Value  Determined?  The net asset value of shares of a
   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 each Trust's Board of Trustees,  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 Oppenheimer funds that offer more than one class of shares.

Service (12b-1) Plan.  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 to pay dealers,  brokers,  banks
   and other financial  institutions  quarterly for providing  personal services
   and maintenance of accounts of their customers that hold shares of the Trust.

How to Sell Shares

Shares can be sold (redeemed) on any regular business day. Orders to sell shares
will  receive the next net asset value per share  calculated  after the order is
received  in proper form  (which  means that it must comply with the  procedures
described below) and is accepted by the Trust's 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 INVESTORS REDEEM SHARES? Direct Investors can redeem their shares
by writing a letter to the  Transfer  Agent,  by using the Trust's  checkwriting
privilege,  or by telephone.  You can also set up Automatic  Withdrawal Plans to
redeem  shares  on a regular  basis.  If you have  questions  about any of these
procedures,  and especially if you are redeeming shares in a special  situation,
such as due to the death of the owner 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  Investors and the
   Trust from fraud,  the following  redemption  requests for accounts of Direct
   Investors 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 $50,000 or more and receive a check
     o The  redemption  check is not  payable  to all  Investors  listed  on the
account statement
     o The redemption check is not sent to the address of record on your account
statement
   o Shares are being transferred to an account with a different owner or name
    o Shares are being redeemed by someone (such as an Executor) other than the
owners

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

How Can Direct  Investors Sell Shares by Mail?  Write a "letter of instructions"
that includes:

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

HowCan Direct  Investors  Sell Shares by Telephone?  Direct  Investors and their
   dealer representative of record may also 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 1-800-525-9310.  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 $50,000  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.

SENDING  REDEMPTION  PROCEEDS BY WIRE.  While the Trust  normally  sends  Direct
Investors  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   Investors   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.

HOW DO I WRITE CHECKS AGAINST MY ACCOUNT?  Program participants may write checks
against the account held under their Program,  but must arrange for checkwriting
privileges  through their  dealers.  Direct  Investors 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.  Investors  with joint  accounts
can elect in writing to have checks paid over the signature of one owner.

   o  Checks can be written to the order of  whomever  you wish,  but may not be
      cashed at the bank the checks are payable through or the Trust's custodian
      bank
   o  Checkwriting privileges are not available for accounts holding shares that
      are subject to a contingent deferred sales charge.
   o  Checks must be written for at least $250.
   o Checks cannot be paid if they are written for more than your account value.
   o You may not write a check that  would  require  the Trust to redeem  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 Oppenheimer fund.
Generally,  there is no fee to redeem  shares of a Trust  bought by  exchange of
shares of another Centennial Trust or Oppenheimer fund. However,

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

      2. those shares are still subject to the Class A contingent deferred sales
         charge when you exchange them into the Trust, then

      3. 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 Trust you exchanged.

How to Exchange Shares

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

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 and  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  or  dealer  and
obtaining a Prospectus of the Centennial Trusts.

HOW CAN DIRECT INVESTORS  EXCHANGE SHARES?  Direct Investors can exchange shares
of a Trust for Class A shares of certain  Oppenheimer funds. To exchange shares,
you must meet several conditions:

   o  Shares of the fund  selected  for exchange  must be available  for sale in
      your place of residence.

   o  The  prospectuses  of the Trust and the fund whose  shares you want to buy
      must offer the exchange privilege.

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

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

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

      Shares of a particular  class of an Oppenheimer fund may be exchanged only
for shares of the same class in other  Oppenheimer  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 Oppenheimer fund for shares of a Trust.

      You may pay a sales  charge when you exchange  shares of a Trust.  Because
shares of a Trust 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 Oppenheimer
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
a Trust or other Oppenheimer funds (except Oppenheimer Cash Reserves), or shares
of a Trust purchased by exchange of shares 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 Investors can find a list of Oppenheimer 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  Investors  Submit Exchange  Requests?  Direct  shareholders  may
     request exchanges in writing or by telephone:

   o  Written Exchange Requests.  Submit 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.  Although the Trusts will attempt to provide you notice  whenever it
      is reasonably able to do so, they may impose these changes at any time.

   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.

Theoffering  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 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.

TheTransfer  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 a Trust will not be liable
   for losses or  expenses  arising  out of  telephone  instructions  reasonably
   believed to be genuine.

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

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

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

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

Dividends and Tax Information

DIVIDENDS.  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.

      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  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  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.

Additional Information About the Trust's Investment Policies and Risks

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

The Trust's Investment  Policies.  The Trust's objective is to seek a high level
of current income consistent with preservation of capital 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, 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  397 days.  Some of the  Trust's  existing
investment  restrictions  are more restrictive than the provisions of Rule 2a-7.
For example,  as a matter of fundamental policy, the Trust may not invest in any
debt  instrument  having a  maturity  in excess of one year from the date of the
investment.  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 IBCA,
Inc.,  Duff and Phelps,  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| 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.

      |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.

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.

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 25% 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.  The Trust  presently  does not intend that the value of
securities loaned will exceed 5% of the value of the Trust's total assets in the
coming  year.  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 Directors.

      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.

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

      |_| The Trust cannot invest in any security other than those  discussed in
the Prospectus under "Investment Objective and Policies";

      |_| The Trust cannot  enter into  repurchase  agreements  maturing in more
than seven days or purchase  securities which are restricted as to resale or for
which market quotations are not readily available,  if any such investment would
cause more than 10% of the Trust's assets to be invested in such securities;

      |_| The  Trust  cannot  borrow  money in excess of 10% of the value of its
total  assets,  and  then  only as a  temporary  measure  for  extraordinary  or
emergency  purposes;  provided that the Trust will not make any  investment at a
time  during  which 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  through (i) the purchase of debt
securities listed in the Prospectus under  "Investment  Objective and Policies,"
(ii) the purchase of such debt securities subject to repurchase  agreements,  or
(iii) loans of  securities  as described  under "Other  Investment  Strategies -
Loans of Portfolio Securities," in this Statement of Additional Information;

      |_| The Trust cannot  invest in any debt  instrument  having a maturity in
excess  of one year from the date of the  investment,  or, in the case of a debt
instrument subject to a repurchase agreement or called for redemption,  having a
repurchase  or  redemption  date  more  than  one  year  from  the  date  of the
investment.

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

      |_|   The Trust cannot invest in real estate;

     |_| 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 its  advisor  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; or

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

      |_| 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.  Examples of those activities  include borrowing
money,   reverse  repurchase   agreements,   delayed-delivery   and  when-issued
arrangements for portfolio securities transactions, and contracts to buy or sell
derivatives, hedging instruments, options or futures.

      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 1982, with an
unlimited number of authorized shares of beneficial interest.

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

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

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

      Shareholders  have the right,  upon the  declaration in writing or vote of
two-thirds  of the  outstanding  shares of the Trust,  to remove a Trustee.  The
Trustees will call a meeting of shareholders to vote on the removal of a Trustee
upon the written request of the record holders of 10% of the outstanding  shares
of the Trust.  If the Trustees  receive a request from at least 10  shareholders
stating  that they wish to  communicate  with  other  shareholders  to request a
meeting to remove a Trustee,  the Trustees will then either make the shareholder
lists of the Trust  available to the applicants or mail their  communication  to
all other shareholders at the applicants'  expense.  The shareholders making the
request must have been shareholders for at least six months and must hold shares
of series 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.  The Declaration of
Trust  further state that the Trustees  shall have no personal  liability to any
such person, to the extent permitted by law.

   1.  For the 1998 calendar year.

      o 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 __________, 1999 the only person who owned of
record or was known by the Trust to own  beneficially  5% or more of the Trust's
outstanding  retail shares was A.G.  Edwards & Sons, Inc.  ("Edwards"),  1 North
Jefferson Avenue, St. Louis,  Missouri 63103, which owned  ________shares of the
Trust which was ____% of the  outstanding  shares of the Trust on that date, for
its own account.

The Manager. The Manager is wholly-owned by  OppenheimerFunds,  Inc., which is a
wholly-owned  subsidiary of Oppenheimer  Acquisition  Corp.,  a holding  company
controlled by Massachusetts  Mutual Life Insurance Company.  The Manager and the
Trust have a Code of Ethics.  It is  designed  to detect  and  prevent  improper
personal trading by certain employees,  including portfolio managers, that would
compete with or take advantage of the Trust's portfolio transactions. Compliance
with the Code of Ethics is carefully monitored and enforced by the Manager.

      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  disinterested  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.

      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 year ended June
30, 1997 and June 30, 1998 June 30, 1999, the  reimbursements  by the Manager to
the Trust were $________, $_________and $________, 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,  a subsidiary of the Manager,
acts as the Trust's  principal  underwriter  and  Distributor  in the continuous
public offering of the Trust's shares.  The Distributor is not obligated to sell
a  specific  number of  shares.  The  Distributor  bears the  expenses  normally
attributable  to  sales,  including  advertising  and the cost of  printing  and
mailing prospectuses, other than those furnished to existing shareholders.

Portfolio  Transactions.  Portfolio decisions are based upon recommendations and
judgment  of the  Manager  subject  to the  overall  authority  of the  Board of
Trustees.  Most  purchases made by the Trust are principal  transactions  at net
prices,  so the Trust  incurs  little or no  brokerage  costs.  The Trust  deals
directly  with the  selling or  purchasing  principal  or market  maker  without
incurring  charges for the services of a broker on its behalf unless the Manager
determines  that a better  price  or  execution  may be  obtained  by using  the
services  of a broker.  Purchases  of  portfolio  securities  from  underwriters
include a commission or concession  paid by the issuer to the  underwriter,  and
purchases from dealers include a spread between the bid and asked prices.

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

      The research services provided by brokers broaden the scope and supplement
the research activities of the Manager.  That research provides additional views
and  comparisons  for  consideration,   and  helps  the  Manager  obtain  market
information  for the  valuation of securities  held in the Trust's  portfolio or
being considered for purchase.

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

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

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
1-800-525-7948.

      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.

      o  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:


                    ( ERV ) 1/n
                    (-----) -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 to
shareholders of the Oppenheimer  funds,  other than performance  rankings of the
Oppenheimer funds themselves.  Those ratings or rankings of investor/shareholder
services by third parties may compare the services of the  Oppenheimer  funds 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.

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.,  by dividing  the value of the Trust's
net assets by the total number of shares outstanding.  All references to time in
this Statement of Additional Information mean New York time. The Exchange's most
recent  annual  announcement  (which is subject to change)  states  that it will
close on New Year's  Day,  Martin  Luther King Jr. Day,  Presidents'  Day,  Good
Friday,  Memorial  Day,  Independence  Day,  Labor  Day,  Thanksgiving  Day  and
Christmas Day. It may also close on other days.

      The Trust's Board of Trustees  have 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  have  established  procedures  reasonably
designed to  stabilize  the  Trust's  net asset value at $1.00 per share.  Those
procedures  include a review 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 they consider  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.

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

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.

Additional Information About the Trust

The Distributor. The Trust's retail shares are sold through dealers, brokers and
other financial  institutions that have a sales charge agreement with Centennial
Asset  Management  Corporation,  the Trust's  Distributor.  The Distributor also
distributes  shares of the other  Oppenheimer funds and is  sub-distributor  for
funds managed by a subsidiary of the Manager.

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

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

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

- -------------------------------------------------------------------------------
                        Description of Securities Ratings
- -------------------------------------------------------------------------------

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

Short-Term Debt Ratings.

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

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

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

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

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

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

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


<PAGE>


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

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

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

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

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

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

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

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


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

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

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

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


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

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

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

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

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

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


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

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

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

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

Long Term Debt Ratings

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

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

Bonds (including municipal bonds) are rated as follows:

Aaa: Judged to be the best quality. They carry the smallest degree of investment
risk  and are  generally  referred  to as "gilt  edge."  Interest  payments  are
protected by a large or by an  exceptionally  stable  margin,  and  principal is
secure. While the various protective elements are likely to change, such changes
as can be  visualized  are most  unlikely  to impair  the  fundamentally  strong
positions of such issues.

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

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

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

Bonds (including municipal bonds) are rated as follows:

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

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

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

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

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

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

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

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

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

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

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

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

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

                                    Exhibit C

- -------------------------------------------------------------------------------
                      AUTOMATIC WITHDRAWAL PLAN PROVISIONS
- -------------------------------------------------------------------------------

By requesting an Automatic  Withdrawal Plan, the shareholder agrees to the terms
and  conditions  applicable to such plans,  as stated below and elsewhere in the
Application for such Plans,  and the Prospectus and this Statement of Additional
Information  as they may be  amended  from time to time by the Trust  and/or the
Distributor.  When adopted, such amendments will automatically apply to existing
Plans.

      Trust shares will be redeemed as necessary  to meet  withdrawal  payments.
Shares  acquired  without a sales charge will be redeemed  first and  thereafter
shares acquired with reinvested  dividends and distributions  followed by shares
acquired  with a sales  charge will be redeemed to the extent  necessary to make
withdrawal  payments.  Depending  upon  the  amount  withdrawn,  the  investor's
principal may be depleted. Payments made to shareholders under such plans should
not be  considered as a yield or income on  investment.  Purchases of additional
shares concurrently with withdrawals are undesirable because of sales charges on
purchases when made.  Accordingly,  a shareholder  may not maintain an Automatic
Withdrawal Plan while simultaneously making regular purchases.

   1.  Shareholder  Services,  Inc.,  the  Transfer  Agent  of the  Trust,  will
administer  the Automatic  Withdrawal  Plan (the "Plan") as agent for the person
(the "Planholder") who executed the Plan authorization and application submitted
to the Transfer Agent.

   2.  Certificates will not be issued for shares of the Trust purchased for and
held under the Plan,  but the Transfer  Agent will credit all such shares to the
account of the  Planholder on the records of the Trust.  Any share  certificates
now held by the Planholder  may be surrendered  unendorsed to the Transfer Agent
with the Plan application so that the shares  represented by the certificate may
be held under the Plan.  Those shares will be carried on the  Planholder's  Plan
Statement.

   3.  Distributions of capital gains must be reinvested in shares of the Trust,
which will be done at net asset value without a sales  charge.  Dividends may be
paid in cash or reinvested.

   4.  Redemptions of shares in connection  with  disbursement  payments will be
made at the net asset value per share determined on the redemption date.

   5. Checks or ACH payments will be  transmitted  three  business days prior to
the date  selected for receipt of the monthly or quarterly  payment (the date of
receipt is  approximate),  according  to the choice  specified in writing by the
Planholder.

   6. The amount and the  interval of  disbursement  payments and the address to
which  checks are to be mailed may be changed at any time by the  Planholder  on
written notification to the Transfer Agent. The Planholder should allow at least
two weeks' time in mailing such notification  before the requested change can be
put in effect.

   7. The  Planholder  may, at any time,  instruct the Transfer Agent by written
notice (in proper form in accordance  with the  requirements of the then current
Prospectus  of the Trust) to redeem  all,  or any part of, the shares held under
the Plan.  In such case,  the  Transfer  Agent will  redeem the number of shares
requested  at the net asset  value per  share in effect in  accordance  with the
Trust's usual  redemption  procedures  and will mail a check for the proceeds of
such redemption to the Planholder.

   8. The Plan may, at any time,  be  terminated  by the  Planholder  on written
notice to the Transfer Agent, or by the Transfer Agent upon receiving directions
to that effect from the Trust.  The Transfer  Agent will also terminate the Plan
upon receipt of evidence  satisfactory to it of the death or legal incapacity of
the Planholder. Upon termination of the Plan by the Transfer Agent or the Trust,
shares  remaining  unredeemed will be held in an  uncertificated  account in the
name   of   the    Planholder,    and   the   account   will   continue   as   a
dividend-reinvestment,   uncertificated   account   unless   and  until   proper
instructions are received from the Planholder,  his executor or guardian,  or as
otherwise appropriate.

   9. For  purposes  of using  shares  held  under the Plan as  collateral,  the
Planholder may request issuance of a portion of his shares in certificated form.
Upon written request from the Planholder,  the Transfer Agent will determine the
number of shares as to which a certificate may be issued, so as not to cause the
withdrawal checks to stop because of exhaustion of uncertificated  shares needed
to continue payments.  Should such uncertificated shares become exhausted,  Plan
withdrawals will terminate.

   10. The Transfer  Agent shall incur no liability  to the  Planholder  for any
action taken or omitted by the Transfer Agent in good faith.

   11. In the event that the Transfer Agent shall cease to act as transfer agent
for the Trust,  the  Planholder  will be deemed to have  appointed any successor
transfer agent to act as his agent in administering the Plan.

Item 24.  Persons Controlled by or Under Common Control with the Fund

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.

Item 26.  Business and Other Connections of Investment Adviser

(a) Centennial  Asset  Management  Corporation is the investment  adviser of the
Registrant;  it and certain subsidiaries and affiliates act in the same capacity

vocation  or  employment  of a  substantial  nature in which  each  officer  and
director of Centennial  Asset  Management  Corporation is, or at any time during
the past two fiscal  years has been,  engaged  for his/her own account or in the

                          INVESTMENT ADVISORY AGREEMENT


     AGREEMENT  made  as of  the  22nd  day of  October,  1990,  by and  between
CENTENNIAL  GOVERNMENT  TRUST  (hereinafter  called the "Fund"),  and CENTENNIAL
ASSET MANAGEMENT CORPORATION  (hereinafter called the "Management  Corporation")
as amended and restated on January 1, 1999.

                                   WITNESSETH:

     WHEREAS, the Fund is an open-end diversified  management investment company
registered  as  such  with  the   Securities   and  Exchange   Commission   (the
"Commission")  pursuant to the Investment  Company Act of 1940 (the  "Investment
Company  Act"),  and  the  Management  Corporation  is a  registered  investment
adviser;

     NOW,  THEREFORE,  in  consideration  of the mutual  promises and agreements
herein contained and other good and valuable consideration, the receipt of which
is hereby  acknowledged,  it is  agreed by and  between  the  parties  hereto as
follows:

1.   General

     The Management  Corporation  agrees, all as more fully set forth herein, to
act as  investment  adviser to the Fund with  respect to the  investment  of its
assets;  to supervise and arrange the purchase of securities for and the sale of
securities  held in the  portfolio  of the Fund;  and to furnish  personnel  and
facilities as shall be required to provide effective administration of the Fund.

2.   Duties  and  Obligations  of the  Management  Corporation  with  respect to
     Investments of Assets of the Fund

     (a) Subject to the succeeding provisions of this section and subject to the
direction  and  control of the Board of  Trustees  of the Fund,  the  Management
Corporation shall:

         (i)   Regularly provide  investment advice and  recommendations  to the
               Fund with respect to its investments, investment policies and the
               purchase and sale of securities;

         (ii)  Supervise continuously the investment program of the Fund and the
               composition of its portfolio; and

         (iii) Arrange,  subject to the provisions of paragraph "4" hereof,  for
               the purchase of securities and other investments for and the sale
               of securities and other  investments held in the portfolio of the
               Fund.

      (b) Any investment  advice furnished by the Management  Corporation  under
this  section  shall at all times  conform to, and be in  accordance  with,  any
requirements  imposed by: (1) the  provisions of the  Investment  Company Act of
1940,  and of any  rules or  regulations  in  force  thereunder;  (2) any  other
applicable  provision of law; (3) the provisions of the Declaration of Trust and
By-Laws  of the  Fund as  amended  from  time to  time;  (4)  any  policies  and
determinations  of the Board of Trustees  of the Fund;  and (5) the terms of the
registration  statement  of the Fund,  as amended  from time to time,  under the
Securities Act of 1933 and the Investment Company Act of 1940.

      (c) The Management Corporation shall give the Fund the benefit of its best
judgment  and  effort  in  rendering  services  hereunder,  but  the  Management
Corporation shall not be liable for any loss sustained by reason of the adoption
of any 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.  Nothing herein  contained shall,  however,  be
construed to protect the  Management  Corporation  against any  liability to the
Fund or its  security  holders  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 this Agreement.

      (d) Nothing in this Agreement shall prevent the Management  Corporation or
any officer thereof from acting as investment adviser for any other person, firm
or  corporation  and  shall  not in any way  limit or  restrict  the  Management
Corporation or any of its directors,  officers,  stockholders  or employees from
buying,  selling or trading any  securities for its or their own accounts or for
the accounts of others for whom it or they may be acting,  provided however that
the  Management  Corporation  expressly  represents  that it will  undertake  no
activities which, in its judgment,  will adversely affect the performance of its
obligations to the Fund under this Agreement.

3.    Allocation of Expenses

      The  Management  Corporation  shall at its expense  provide all executive,
administrative  and clerical personnel as shall be required to provide effective
administration  for the Fund,  including  the  compilation  and  maintenance  of
records with  respect to its  operations  as may  reasonably  be  required;  the
preparation and filing of such reports with respect thereto as shall be required
by rules or regulations  promulgated by the Securities and Exchange  Commission;
the composition of registration  statements  required by Federal securities laws
for  continuous  public  sale of  shares of the Fund;  composition  of  periodic
reports with respect to its  operations  for the  shareholders  of the Fund; and
composition  of proxy  materials  for meetings of the Fund's  shareholders.  The
Management Corporation shall, at its own cost and expense, also provide the Fund
with adequate office space, facilities and equipment. The Management Corporation
shall,  at its own  expense,  provide  such  officers for the Fund as the Fund's
Board may request.  All other costs and expenses  not  expressly  assumed by the
Management  Corporation  under  this  Agreement,  or to be paid  by the  General
Distributor of the shares of the Fund, shall be paid by the Fund, including, but
not limited to (i) interest and taxes; (ii) brokerage commissions, if any; (iii)
insurance  premiums for fidelity and other coverage requisite to its operations;
(iv)  compensation  and expenses of its Trustees other than those  associated or
affiliated with the Management  Corporation;  (v) legal and audit expenses; (vi)
custodian and transfer agent fees and expenses;  (vii) expenses  incident to the
redemption of its shares; (viii) expenses incident to the issuance of its shares
against payment therefor by or on behalf of the subscribers  thereto;  (ix) fees
and expenses,  other than as hereinabove provided,  incident to the registration
under Federal and State  securities  laws of shares of the Fund for public sale;
(x) expenses of printing and mailing  reports,  notices,  and proxy  material to
shareholders  of the Fund;  (xi)  except  as noted  above,  all  other  expenses
incidental to holding  regular annual meetings of the Fund's  shareholders;  and
(xii)  such  extraordinary   non-recurring  expenses  as  may  arise,  including
litigation  affecting the Fund and the legal  obligation which the Fund may have
to indemnify its officers and Trustees with respect thereto.

4.    Portfolio Transactions and Brokerage

      (a) The Management Corporation is authorized, for the purchase and sale of
the Fund's portfolio  securities,  to employ such securities  dealers as may, in
the best  judgment of the  Management  Corporation,  implement the policy of the
Fund to obtain prompt and reliable execution of orders at the most favorable net
price.  Consistent with this policy, the Management Corporation is authorized to
direct the execution of the Fund's portfolio  transactions to dealers furnishing
statistical  information or research deemed by the Management  Corporation to be
useful or valuable to the performance of its investment  advisory  functions for
the Fund.

5.    Compensation of the Management Corporation

      (b) Regardless of any of the above provisions,  the Management Corporation
guarantees that the total expenses of the Fund in any fiscal year,  exclusive of
taxes, interest and brokerage  commissions,  and extraordinary  expenses such as
litigation costs, shall not exceed, and the Management Corporation undertakes to
pay or refund to the Fund any amount by which  such  expenses  shall  exceed the
lesser  of (i)  1.5% of the  average  annual  net  assets  of the Fund up to $30
million and 1% of its  average  annual net assets in excess of $30  million;  or

 6.   Use of Name

      The  Management  Corporation  hereby  grants  to the Fund a  royalty-free,
non-exclusive  license to use the name "Centennial" in the name of the Fund, and
any trademarks or service marks, whether or not registered, which it may own. To
the extent necessary to protect the Management  Corporation's rights to the name
"Centennial"  under  applicable  law,  such license  shall allow the  Management
Corporation to inspect and, subject to control by the Fund's Board,  control the
nature and quality of services  offered by the Fund under such name. The license
may be  terminated  by the  Management  Corporation  upon  termination  of  this
Agreement  in which case the Fund  shall  have no further  right to use the name
"Centennial"  in its name or otherwise or any of such marks,  and the Fund,  the
holders of its  shares,  and its  officers  and  Trustees  shall  promptly  take
whatever  action  may be  necessary  to change  its name  accordingly.  The name
"Centennial"  or any of said  marks may be used or  licensed  by the  Management
Corporation  in  connection  with  any of its  activities,  or  licensed  by the
Management Corporation to any other party.

7.    Duration and Termination

      (a) This Agreement  shall go into effect on the date first set forth above
and shall continue in effect until  December 31, 1991, and thereafter  from year
to year, but only so long as such continuance is specifically  approved at least
annually  by the Board of  Trustees,  including  the vote of a  majority  of the
Trustees  of the Fund  who are not  parties  to this  Agreement  or  "interested
persons"  (as defined in the  Investment  Company Act of 1940) of any such party
cast in person at a meeting  called for the purpose of voting on such  approval,
or by the vote of the holders of a "majority" (as so defined) of the outstanding
voting securities of the Fund and by such a vote of the Board of Trustees.

      (b) This Agreement may be terminated by the Management  Corporation at any
time without  penalty  upon giving the Fund sixty days'  written  notice  (which
notice may be waived by the Fund) and may be  terminated by the Fund at any time
without penalty upon giving the Management Corporation sixty days' notice (which
notice  may be  waived  by  the  Management  Corporation),  provided  that  such
termination  by the Fund shall be directed or approved by the vote of a majority
of all of the  Trustees of the Fund then in office or by the vote of the holders
of a "majority" (as defined in the Investment Company Act of 1940) of the voting
securities  of the Fund at the  time  outstanding  and  entitled  to vote.  This
Agreement shall  automatically  terminate in the event of its  "assignment"  (as
that term is defined in the Investment Company Act of 1940).

8.    Disclaimer of Shareholder Liability

      The  Management  Corporation  understands  that  the  obligations  of this
Agreement  are  not  binding  upon  any  Trustee  or  shareholder  of  the  Fund
personally,  but bind  only the  Fund's  property.  The  Management  Corporation
represents  that it has notice of the  provisions  of the  Declaration  of Trust
disclaiming  Trustee and  shareholder  liability for acts or  obligations of the
Fund.

      IN  WITNESS  WHEREOF,   the  parties  hereto  have  caused  the  foregoing
instrument to be executed by their duly authorized officers as of the 1st day of
January, 1999.
