The Trust's Objective and Investment Strategies

- ------------------------------------------------------------------------------
   
What  Is the  Trust's  Investment  Objective?  The  Trust  seeks  the  maximum
    
current  income that is consistent  with low capital risk and the  maintenance
of liquidity.
- ------------------------------------------------------------------------------

What Does the Trust Invest In? The Trust is a money market fund. It invests in a
variety of  high-quality  money market  securities to seek income.  Money market
securities  are  short-term  debt  instruments  issued  by the U.S.  government,
domestic and foreign corporations and financial institutions and other entities.
They include, for example,  bank obligations,  commercial paper, other corporate
debt obligations and government debt obligations.

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.
    

      The Trust's investment manager,  Centennial Asset Management  Corporation,
tries to reduce risks by diversifying  investments and by carefully  researching
securities before they are purchased. However, 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  performance  for a class of shares of the Trust from
year to year for the last ten calendar years and average annual total returns on
that share class offered prior to the date of this prospectus for the 1-, 5- and
10- year periods. Because Class Y shares have not been offered prior to the date
of this prospectus, information in the bar chart and the table show below is for
the Trust's  existing  share  class.  That share  class has no  alphabet  letter
designation  and is referred to in this  Prospectus as the Trust's "retail share
class." The retail share class is offered by a separate prospectus.  Variability
of returns is one measure of the risks of investing in a money market fund.  The
past investment performance of the share class shown below is not necessarily an
indication  of how  either of the  Trust's  share  classes  will  perform in the
future.
    

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

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

   
For the period  from 1/1/99  through  3/31/99 the  cumulative  total  return was
1.07%.  During  the  period  shown in the bar chart,  the  highest  return for a
calendar  quarter  was 2.28%  (2nd Q '89) and the  lowest  return for a calendar
quarter was 0.65% (1st Q '93).

periods                     1 Year            if less)            if less)

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

   
The returns in the table measure the  performance of a hypothetical  account and
assume that all  dividends  have been  reinvested  in  additional  shares of the
retail  share  class.  Class Y shares  were not  offered  during the year ending
December 31, 1998.  Accordingly,  no performance information is shown on Class Y
shares.  The total returns are not the Trust's current yield.  The Trust's yield
more closely reflects the Trust's current earnings.

toll-free at 1-800-525-9310.
    
- ------------------------------------------------------------------------------

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 Class Y shares of the Trust.  The numbers  below are based upon the Trust's
expenses  for its retail share class during the fiscal year ended June 30, 1998.
Class Y shares were not offered during the fiscal year ended June 30, 1998.

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

 Other Expenses                                            0.03%
    
 ------------------------------------------------------------------------------
 ------------------------------------------------------------------------------
   
 Total Annual Operating Expenses                           0.37%
    
 ------------------------------------------------------------------------------
 "Other expenses" in the table include transfer agent fees,  custodial fees, and
accounting and legal expenses the Trust pays.

   
The Annual Operating Expenses are estimated based on the expenses of the Trust's
retail  share class during the Trust's  fiscal year ended June 30,  1998.  It is
anticipated  that  expenses of the Trust's Class Y shares will be lower than the
Trust's  retail share class because Class Y shares will not incur a service plan
fee and transfer agency expenses  (included in "Other Expenses") are anticipated
to be lower for Class Y shares.
    

Example.  This  example is intended to help you compare the cost of investing in
the Trust with the cost of investing in other mutual funds.  The example assumes
that you invest  $10,000 in shares of the Trust for the time and  reinvest  your
dividends and distributions. The example also assumes that your investment has a
5% return each year and that the Trust's  expenses  remain the same. Your actual
costs may be higher or lower,  because  expenses  will vary over time.  Based on
these assumptions your expenses would be as follows:

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

About the Trust's Investments

   
The Trust's Principal Investment Policies. In seeking the maximum current income
that is consistent with low capital risk 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.

      n 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.

      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.  These are referred to as "U.S.  government  securities" in
this  Prospectus.  To  produce  income  that is not  subject  to U.S.  federal
income  tax  withholding  for its  shareholders,  the  Trust  invests  in U.S.
government securities issued after July 18, 1984, in registered form.

   o  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.

   o  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.
    

   Bank  Obligations.  The Trust may buy  certificates  of  deposit,  bankers'
acceptances, and other bank obligations.  They must be :

   o  obligations  of a  domestic  bank  having  total  assets  of at least $1
      billion or

   o  U.S. dollar-denominated  obligations of a foreign bank with total assets
      of at least U.S. $1 billion.

      No more than 25% of the Trust's  assets  will be  invested  in  securities
issued by foreign banks.  That limitation does not apply to securities issued by
foreign branches of U.S. banks.

      o Commercial Paper. Commercial paper is a short-term, unsecured promissory
note of a  domestic  or  foreign  company.  The Trust may buy  commercial  paper
maturing in nine  months or less from the date of purchase  only if it meets the
Trust's quality standards, described below.

      o  Corporate  Obligations.  The  Trust  may  invest  in  other  short-term
corporate  debt  obligations,  besides  commercial  paper,  that at the  time of
purchase by the Trust meet the Trust's quality standards, described below.

      o Other Money  Market  Obligations.  The Trust may invest in money  market
obligations  other than those  listed  above if they are  subject to  repurchase
agreements  calling for delivery in twelve  months or less or  guaranteed  as to
their principal and interest by the U.S.  Government or one of its agencies,  or
by bank or a corporation  whose  commercial paper may be purchased by the Trust.
The  guaranteed  obligations  must be due within  twelve months or less from the
date of purchase.

      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.

   
      o 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.

   
      o Can the 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.
    

     o  Asset-Backed   Securities.   The  Trust  may  invest  in   asset-backed
securities.  These are fractional interests in pools of consumer loans and other
trade receivables.  They are backed by a pool of assets,  such as credit card or
auto loan  receivables,  which  are the  obligations  of a number  of  different
parties. The income from the underlying pool is passed through to holders,  such
as the Trust.

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

      o  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 guarantees payment.

     o 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.

      o 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 and other  securities  that are not
readily marketable.  That limit does not apply to certain restricted  securities
that are eligible for resale to qualified institutional  purchasers or purchases
of  commercial  paper that may be sold  without  registration  under the Federal
securities  laws. The Trust may invest up to 25% of its net assets in restricted
securities,  subject  to the 10%  limit  on  illiquid  securities.  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.
    

How the Trust is Managed

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

   
      The Manager,  a  wholly-owned  subsidiary of  OppenheimerFunds,  Inc., has
operated as an  investment  advisor since 1978.  The Manager and its  affiliates
currently advise  investment  companies with assets of more than $100 billion as
of March  31,  1999,  and with more than 4  million  shareholder  accounts.  The
Manager is located at 6803 South Tucson Way, Englewood, CO 80112.
    

      o Portfolio Managers. Carol E. Wolf and Arthur J. Zimmer are the portfolio
managers of the Trust.  They are the  persons  principally  responsible  for the
day-to-day  management  of  the  Trust's  portfolio.   Ms.  Wolf  has  had  this
responsibility since October 1990 and Mr. Zimmer since January 1991. Ms. Wolf is
a Vice  President  and Mr. Zimmer a Senior Vice  President of  OppenheimerFunds,
Inc.,  and each is an officer  and  portfolio  manager of other  funds for which
OppenheimerFunds, Inc. or the Manager serves as investment advisor.

     o Advisory Fees. Under the Investment  Advisory  Agreement,  the Trust pays
the Manager an advisory fee at an annual rate that declines on additional assets
as the Trust grows:  0.500% of the first $250  million of net assets;  0.475% of
the next $250  million  of net  assets;  0.450% of the next $250  million of net
assets;  0.425% of the next $250 million of net assets;  0.400% of the next $250
million of net assets;  0.375% of the next $250 million of net assets; 0.350% of
the next $500  million of net  assets;  and 0.325% of net assets in excess of $2
billion.  Furthermore,  the Manager  guarantees  that the total  expenses of the
Trust  in  any  fiscal  year,   exclusive  of  taxes,   interest  and  brokerage
commissions,  and  extraordinary  expenses such as litigation  costs,  shall not
exceed,  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, 1998
was 0.34% of the Trust's average annual net assets.

How to Buy Shares

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

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

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

      n Guaranteed Payment Procedures. Some broker-dealers may have arrangements
with the  Distributor to enable them to place  purchase  orders for Trust shares
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 Trust shares.

o     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.

o     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.

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

How Much Must You Invest? You can open account with a minimum initial investment
of $10 million  and make  additional  investments  at any time with as little as
$500,000.  The  minimum  investment  requirement  does not apply to  reinvesting
dividends from the Trust.
    

At What Price Are Shares Sold? Shares are sold at their offering price, which is
the net asset value per share without any sales charge.  The net asset value per
share  will  normally  remain  fixed at $1.00 per  share.  However,  there is no
guarantee  that the Trust will  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.

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

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

- ------------------------------------------------------------------------------
What Classes of Shares Does the Trust Offer?  The Trust offers  investors  two
   
different  classes  of  shares.   One  share  class  is  designed  for  retail
investors  and  another  share class is  designed  for  certain  institutional
investors.  The different classes of shares represent  investments in the same
    
portfolio of  securities,  but the classes are subject to  different  expenses
   
and will likely have  different  share prices.  The Trust's retail share class
    
is are  offered by a separate  prospectus  dated  October  30,  1998.  Class Y
shares are offered  only to certain  institutional  investors  who have  special
agreements with the Distributor.
- ------------------------------------------------------------------------------

Who Can Buy Class Y  Shares?  Class Y shares  are sold at net asset  value per
share without sales charge  directly to certain  institutional  investors that
have special  agreements  with the  Distributor  for this purpose.  Individual
investors cannot buy Class Y shares directly.

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

How to Sell Shares

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

If you participate in an Automatic  Purchase and Redemption Program sponsored by
your  broker-dealer,  you may  redeem  shares  held in your  Program  Account by
contacting  your  broker  or  dealer.   You  may  also  arrange  for  "Expedited
Redemptions"  as  described  below  through  your broker or dealer.  If you have
questions  about any of these  procedures,  and  especially if you are redeeming
shares in a special  situation,  such as due to the death of the owner or from a
retirement plan account, please call the Transfer Agent for assistance first, at
1-800-525-9310.

      n Certain Requests Require a Signature  Guarantee.  To protect you and the
Trust from fraud, the following  redemption requests must be in writing and must
include a signature  guarantee (although there may be other situations that also
require a signature guarantee):
      o You wish to redeem  $50,000 or more and receive a check o The redemption
      check is not payable to all shareholders listed on
the account statement
      o  The  redemption  check is not sent to the  address  of record on your
account statement
      o  Shares  are being  transferred  to a Fund  account  with a  different
owner or name
      o  Shares are being  redeemed  by someone  (such as an  Executor)  other
than the owners

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

      o Sending Redemption Proceeds by Wire. While the Trust normally sends your
money by check, you can arrange to have the proceeds of the shares you sell sent
by Federal Funds wire to a bank account you  designate.  It must be a commercial
bank that is a member of the Federal Reserve wire system. The minimum redemption
you can have sent by wire is $2,500.  There is a $10 fee for each wire.  To find
out how to set up this  feature on your  account or to arrange a wire,  call the
Transfer Agent at 1-800-525-9310.

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

How Do I Sell Shares by Telephone?  To receive the redemption price on a regular
business  day, the Transfer  Agent must receive the request by 4:00 P.M. on that
day. You may not redeem shares held under a share  certificate by telephone.  To
redeem shares through a service representative, call 1-800-852-8457. Proceeds of
telephone  redemptions  will be paid by check payable to the  shareholder(s)  of
record and will be sent to the address of record for the account.  Up to $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.

Can I Sell Shares Through My Dealer?  The Distributor  has made  arrangements to
repurchase  Trust shares from dealers and brokers on behalf of their  customers.
Brokers or dealers may charge for that  service.  If your shares are held in the
name of your dealer, you must redeem them through your dealer.

Will I Pay a Sales Charge When I Sell My Shares? The Trust does not charge a fee
when you redeem  Class Y shares of this Trust  that you  bought  directly  or by
reinvesting dividends or distributions from the Trust.

Shareholder Account Rules and Policies

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

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

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

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

     o 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.

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

      o 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.

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

      o To avoid sending duplicate copies of materials to households,  the Trust
will mail only one copy of each annual and  semi-annual  report to  shareholders
having the same last name and  address on the  Trust's  records.  However,  each
shareholder may call the Transfer Agent at  1-800-525-7048 to ask that copies of
those materials be sent personally to that shareholder.

Dividends and Tax Information

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

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

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

   
Taxes.  If your shares are not held in a tax-deferred  retirement  account,  you
should be aware of the  following  tax  implications  of investing in the Trust.
Dividends  paid from net  investment  income and  short-term  capital  gains are
taxable as ordinary  income.  Long-term  capital  gains are taxable as long-term
capital gains when  distributed to  shareholders  Trust.  It does not matter how
long you have held your  shares.  Whether you  reinvest  your  distributions  in
additional shares or take them in cash, the tax treatment is the same.

      Every year the Trust  will send you and the IRS a  statement  showing  the
amount of each  taxable  distribution  you received in the  previous  year.  Any
long-term capital gains  distributions will be separately  identified in the tax
information the Trust sends you after the end of the calendar year.

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

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

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

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 the maximum
current income that is consistent  with low capital risk and the  maintenance of
liquidity.  The Trust will not make  investments  with the  objective of seeking
capital  growth.  However,  the value of the securities held by the Trust may be
affected by changes in general interest rates. Because the current value of debt
securities  varies  inversely  with changes in  prevailing  interest  rates,  if
interest  rates  increase  after a security is purchased,  that  security  would
normally  decline in value.  Conversely,  if  interest  rates  decrease  after a
security is purchased,  its value would rise.  However,  those  fluctuations  in
value will not generally  result in realized  gains or losses to the Trust since
the Trust  does not  usually  intend to  dispose  of  securities  prior to their
maturity.  A debt  security held to maturity is redeemable by its issuer at full
principal value plus accrued interest.

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

      |X|  Ratings  of   Securities   --   Portfolio   Quality,   Maturity   and
Diversification.  Under Rule 2a-7 of the Investment  Company Act, 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| Bank Obligations.  The types of "banks" whose securities the Trust may
buy include commercial banks,  savings banks, and savings and loan associations,
which may or may not be members of the Federal  Deposit  Insurance  Corporation.
Within the limits set forth in the Prospectus, the Trust may also buy securities
of "foreign banks" that are:
      |_|   foreign  branches  of  U.S.  banks  (which  may  be  issuers  of
      "Eurodollar" money market instruments),
      |_|   U.S.  branches and agencies of foreign banks (which may be issuers
      of "Yankee dollar" instruments), or
      |_|   foreign branches of foreign banks.

   
     |X| Asset-Backed Securities. These securities, issued by trusts and special
purpose  corporations,  are backed by pools of  assets.  They pass  through  the
payments on the underlying  obligations to the security  holders (less servicing
fees paid to the originator or fees for any credit enhancement). The value of an
asset-backed  security is affected by changes in the market's  perception of the
asset backing the security,  the creditworthiness of the servicing agent for the
loan pool, the originator of the loans, or the financial  institution  providing
any credit enhancement.
    
      Payments  of  principal  and  interest   passed   through  to  holders  of
asset-backed   securities  are  typically  supported  by  some  form  of  credit
enhancement,  such as a letter of credit,  surety  bond,  limited  guarantee  by
another  entity  or  having  a  priority  to  certain  of the  borrower's  other
securities.  The degree of credit  enhancement  varies, and generally applies to
only a fraction of the asset-backed security's par value until exhausted. If the
credit  enhancement  of an  asset-backed  security  held by the  Trust  has been
exhausted,  and if any required  payments of principal and interest are not made
with respect to the underlying  loans, the Trust may experience losses or delays
in receiving payment.

     The risks of investing in asset-backed  securities are ultimately dependent
upon payment of underlying  assets. As a purchaser of an asset-backed  security,
the Trust would  generally  have no recourse to the entity that  originated  the
loans in the event of default by a borrower. The underlying loans are subject to
prepayments,  which shorten the weighted average life of asset-backed securities
and may lower their return,  in the same manner as for  prepayments of a pool of
mortgage loans  underlying  mortgage-backed  securities.  However,  asset-backed
securities  do not  have  the  benefit  of the  same  security  interest  in the
underlying collateral as do mortgage-backed securities.

      |X| Repurchase Agreements. In a repurchase transaction, the Trust acquires
a  security  from,  and  simultaneously  resells it to, an  approved  vendor for
delivery on an  agreed-upon  future date.  The resale price exceeds the purchase
price by an amount that reflects an agreed-upon  interest rate effective for the
period during which the repurchase  agreement is in effect. An "approved vendor"
may be a U.S.  commercial bank or the U.S. branch of a foreign bank having total
domestic assets of at least $1 billion, or a broker-dealer with a net capital of
$50 million which has been designated a primary dealer in government securities.

     The  majority  of these  transactions  run from  day to day,  and  delivery
pursuant  to the  resale  typically  will  occur  within one to five days of the
purchase.  The Trust will not enter into a repurchase  agreement that will cause
more than 10% of its net assets to be subject to repurchase  agreements maturing
in more than seven days.

      Repurchase  agreements are considered "loans" under the Investment Company
Act,   collateralized  by  the  underlying  security.   The  Trust's  repurchase
agreements  require  that at all times  while  the  repurchase  agreement  is in
effect,  the  collateral's  value must equal or exceed the  repurchase  price to
fully  collateralize the repayment  obligation.  Additionally,  the Manager will
impose  creditworthiness  requirements 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  to lend its
securities,  but if it does,  the value of securities  loaned is not expected to
exceed 5% of the value of the  Trust's  total  assets.  There are some  risks in
lending securities.  The Trust could experience a delay in receiving  additional
collateral to secure a loan, or a delay in recovering the loaned securities.

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

      When it lends  securities,  the Trust receives from the borrower an amount
equal to the interest  paid or the dividends  declared on the loaned  securities
during the term of the loan.  It may also receive  negotiated  loan fees and the
interest  on  the   collateral   securities,   less  any  finders',   custodian,
administrative  or other fees the Trust pays in  connection  with the loan.  The
Trust may share the interest it receives on the collateral  securities  with the
borrower as long as it realizes at least a minimum  amount of interest  required
by the lending guidelines established by its Board of 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.

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

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

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

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.

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

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

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

      |_| The Trust cannot  concentrate  investments to the extent of 25% of its
assets in any  industry;  however,  there is no  limitation  as to investment in
obligations issued by banks, savings and loan associations or the U.S.
Government and its agencies or instrumentalities.

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

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

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

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

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

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

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

     o The Trust cannot underwrite securities of other companies.

      |_| 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.

      |_| The Trust cannot invest in securities of other  investment  companies,
except in connection with a consolidation or merger.

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

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

   
How the Trust Is Managed
    

Organization  and  History.  The Trust is an  open-end,  diversified  management
investment company organized as a Massachusetts  business trust in 1979, with an
unlimited number of authorized shares of beneficial interest.

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

   
      |X|  Classes  of Shares.  The Board of  Trustees  has the  power,  without
shareholder  approval,  to divide  unissued shares of the Trust into two or more
classes.  The Board has done so,  and the Trust  currently  has two  classes  of
shares. Prior to the date of this Statement of Additional Information, the Trust
offered a single share class to investor. That share class is referred to herein
as its "retail  share  class." The  Trust's  Class Y shares are offered  only to
certain  institutional  investors.  All  classes  invest in the same  investment
portfolio.  Shares  are  freely  transferable.   Each  share  has  one  vote  at
shareholder  meetings,  with fractional shares voting  proportionally on matters
submitted to the vote of shareholders. Each class of shares:
    
     |_| has its own dividends and distributions,
     |_| pays certain expenses which may be different for the different classes,

     |_|  may have a different net asset value,
     |_| may have separate voting  rights on matters in which the  interests of
         one class are different from the interests of another class, and
     |_|  votes as a class on matters  that  affect that class alone.

      |X| Meetings of Shareholders. As a 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 May 11,  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  18,445,902,882.960
shares of the Trust which was 98.75% 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.

      Independently  of the  investment  advisory  agreement,  the  Manager  had
voluntarily agreed to waive a portion of the management fee otherwise payable to
it by the Trust  during the period from  December 1, 1991  through  November 21,
1997. For fiscal year ended June 30, 1996,  June 30, 1997 and June 30, 1998, the
reimbursements  by the Manager to the Trust were $0,  $4,890,123 and $2,382,437,
respectively.  Contemporaneously  with the  amendment of the Trust's  investment
advisory  agreement with the Manager,  the Manager withdrew its voluntary waiver
on November 21, 1997.

    The  investment  advisory  agreement  states  that in the absence of willful
misfeasance,  bad faith,  gross  negligence in the  performance of its duties or
reckless  disregard of its obligations and duties under the investment  advisory
agreement,  the Manager is not liable for any loss  resulting  from a good faith
error or  omission  on its part  with  respect  to any of its  duties  under the
agreement.

      |X| The Distributor.  Under its General  Distributor's  Agreement with the
Trust,  Centennial  Asset Management  Corporation,  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.

   
      Any unaudited  interim  financial  statements  furnished shall reflect all
adjustments  which  are,  in the  opinion  of  management,  necessary  to a fair
statement of the results for the interim periods presented.

Short-term notes, bankers'  acceptances,  direct bank obligations and letters of
credit  are  generally  traded on a discount  basis;  the  interest  rate is the
discount  rate received by the Trust at the time of purchase.  Other  securities
normally bear interest at the rates shown.

1. Floating or variable rate  obligation.  The interest rate,  which is based on
   specific,  or an index  of,  market  interest  rates,  is  subject  to change
   periodically  and is the effective rate on June 30, 1998. This instrument may
   also  have a demand  feature  which  allows,  on up to 30 days'  notice,  the
   recovery of principal at any time,  or at specified  intervals  not exceeding
   one year. Maturity date shown represents effective maturity based on variable
   rate and, if applicable, demand feature.

2. Represents a restricted security which is considered  illiquid,  by virtue of
   the absence of a readily  available market or because of legal or contractual
   restrictions on resale.  Such securities amount to $514,069,521,  or 3.40% of
   the  Trust's  net  assets.  The Trust may not invest more than 10% of its net
   assets (determined at the time of purchase) in illiquid securities.

3. Security  issued  in an exempt  transaction  without  registration  under the
   Securities Act of 1933. Such securities amount to  $2,814,234,915,  or 18.62%
   of the Trust's net assets,  and have been determined to be liquid pursuant to
   guidelines adopted by the Board of Trustees.

4. Represents   securities   sold  under  Rule  144A,   which  are  exempt  from
   registration  under the Securities Act of 1933, as amended.  These securities
   have been determined to be liquid under  guidelines  established by the Board
   of Trustees. These securities amount to $125,000,000, or 0.83% of the Trust's
   net assets as of June 30, 1998.

Centennial Money Market Trust


1. SIGNIFICANT ACCOUNTING POLICIES

Centennial  Money Market Trust (the Trust) is  registered  under the  Investment
Company  Act  of  1940,  as  amended,  as  a  diversified,  open-end  management
investment  company.  The Trust's  investment  objective  is to seek the maximum
current income that is consistent  with low capital risk and the  maintenance of
liquidity.  The Trust seeks to achieve  this  objective  by  investing in "money
market" securities  meeting specified quality standards.  The Trust's investment
advisor is Centennial Asset Management  Corporation (the Manager),  a subsidiary
of  OppenheimerFunds,  Inc.  (OFI).  The  following is a summary of  significant
accounting policies consistently followed by the Trust.

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

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

Federal  Taxes-The  Trust  intends to continue to comply with  provisions of the
Internal  Revenue Code  applicable  to  regulated  investment  companies  and to
distribute  all of its taxable  income to  shareholders.  Therefore,  no federal
income or excise tax provision is required.

Distributions to  Shareholders-The  Trust intends to declare  dividends from net
investment  income each day the New York Stock Exchange is open for business and
pay such  dividends  monthly.  To effect its policy of  maintaining  a net asset
value of $1.00 per share, the Trust may withhold dividends or make distributions
of net realized gains.

Other-Investment  transactions are accounted for on the date the investments are
purchased or sold (trade date).  Realized  gains and losses on  investments  are
determined on an identified cost basis, which is the same basis used for federal
income tax purposes.

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


                                                                              23

3. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Management  fees paid to the  Manager  were in  accordance  with the  investment
advisory agreement with the Trust which provides for a fee of 0.50% of the first
$250 million of net assets; 0.475% of the next $250 million of net assets; 0.45%
of the next $250  million of net assets;  0.425% of the next $250 million of net
assets; and 0.40% on net assets in excess of $1 billion.  The Manager has agreed
to reimburse the Trust if aggregate expenses (with specified  exceptions) exceed
the lesser of 1.5% of the first $30 million of average  annual net assets of the
Trust, plus 1% of average annual net assets in excess of $30 million;  or 25% of
the total annual investment income of the Trust.

Independently of the investment advisory agreement,  the Manager has voluntarily
agreed to waive a portion of the management  fee otherwise  payable to it by the
Trust to the extent necessary to reduce,  on an annual basis, the management fee
paid on the average  net assets of the Trust in excess of $1 billion  from 0.40%
to:  0.40% of average  net  assets in excess of $1  billion  but less than $1.25
billion;  0.375% of average net assets in excess of $1.25  billion but less than
$1.50  billion;  0.35% of average net assets in excess of $1.50 billion but less
than $2 billion;  and 0.325% of average net assets in excess of $2 billion.  The
investment advisory agreement was amended on November 21, 1997 to include in the
contractual  management fee those  additional break points which were previously
voluntary.

Short-term notes,  direct bank obligations,  letters of credit,  U.S. government
agencies and foreign  government  obligations are generally traded on a discount
basis;  the interest rate is the discount rate received by the Trust at the time
of purchase. Other securities normally bear interest at the rates shown.

1. Floating or variable rate  obligation.  The interest rate,  which is based on
specific,  or  an  index  of,  market  interest  rates,  is  subject  to  change
periodically and is the effective rate on December 31, 1998. This instrument may
also have a demand feature which allows, on up to 30 days' notice,  the recovery
of principal at any time,  or at specified  intervals  not  exceeding  one year.
Maturity date shown represents effective maturity based on variable rate and, if
applicable, demand feature.

2. Represents a restricted security which is considered  illiquid,  by virtue of
the  absence of a readily  available  market or because of legal or  contractual
restrictions on resale. Such securities amount to $624,688,000,  or 3.70% of the
Trust's  net  assets.  The Trust may not invest  more than 10% of its net assets
(determined at the time of purchase) in illiquid securities.

3.  Security  issued in an exempt  transaction  without  registration  under the
Securities Act of 1933. Such securities amount to  $3,486,814,151,  or 20.67% of
the  Trust's  net  assets,  and have been  determined  to be liquid  pursuant to
guidelines adopted by the Board of Trustees.

4.  Represents   securities  sold  under  Rule  144A,   which  are  exempt  from
registration under the Securities Act of 1933, as amended. These securities have
been  determined  to be  liquid  under  guidelines  established  by the Board of
Trustees.  These  securities  amount to $383,027,980 or 2.27% of the Trust's net
assets as of December 31, 1998.

Centennial Money Market Trust

1. Significant Accounting Policies

Centennial  Money Market Trust (the Trust) is  registered  under the  Investment
Company  Act  of  1940,  as  amended,  as  a  diversified,  open-end  management
investment  company.  The Trust's  investment  objective  is to seek the maximum
current income that is consistent  with low capital risk and the  maintenance of
liquidity.  The Trust seeks to achieve  this  objective  by  investing in "money
market" securities  meeting specified quality standards.  The Trust's investment
advisor is Centennial Asset Management  Corporation (the Manager),  a subsidiary
of  OppenheimerFunds,  Inc.  (OFI).  The  following is a summary of  significant
accounting policies consistently followed by the Trust.

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

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

Federal  Taxes.  The Trust intends to continue to comply with  provisions of the
Internal  Revenue Code  applicable  to  regulated  investment  companies  and to
distribute  all of its taxable  income to  shareholders.  Therefore,  no federal
income or excise tax provision is required.

Distributions to Shareholders.  The Trust intends to declare  dividends from net
investment  income each day the New York Stock Exchange is open for business and
pay such  dividends  monthly.  To effect its policy of  maintaining  a net asset
value of $1.00 per share, the Trust may withhold dividends or make distributions
of net realized gains.

Other. Investment transactions are accounted for on the date the investments are
purchased or sold (trade date).  Realized  gains and losses on  investments  are
determined on an identified cost basis, which is the same basis used for federal
income tax purposes.

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

3. Management Fees and Other Transactions with Affiliates

Management  fees paid to the  Manager  were in  accordance  with the  investment
advisory agreement with the Trust which provides for a fee of 0.50% of the first
$250  million of average  annual net assets;  0.475% of the next $250 million of
average annual net assets;  0.45% of the next $250 million of average annual net
assets;  0.425% of the next $250 million of average annual net assets;  0.40% of
the next $250  million of average  annual  net  assets;  0.375% of the next $250
million of average annual net assets;  0.35% of the next $500 million of average
annual  net  assets;  and  0.325% of  average  annual net assets in excess of $2
billion.  The Manager has agreed to reimburse  the Trust if  aggregate  expenses
(with specified  exceptions)  exceed the lesser of 1.5% of the first $30 million
of average annual net assets of the Trust,  plus 1% of average annual net assets
up to $30 million;  or 25% of the total annual  investment  income of the Trust.
The Trust's management fee for the six months ended December 31, 1998, was 0.34%
of the average annual net assets of the Trust.

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

Under an  approved  service  plan,  the Trust may  expend up to 0.20% of its net
assets  annually to reimburse  certain  securities  dealers and other  financial
institutions and organizations for costs incurred in distributing Trust shares.

4. Acquisition of Daily Cash Accumulation Fund, Inc.

On  November  21,  1997,  the  Trust  acquired  the net  assets  of  Daily  Cash
Accumulation  Fund,  Inc. The Trust issued  3,461,468,087  shares of  beneficial
interest, valued at $3,460,935,372, in exchange for the net assets, resulting in
combined  net assets of  $13,332,466,315  on November  21,  1997.  The  exchange
qualified as a tax-free reorganization for federal income tax purposes.

- ------------------------------------------------------------------------------
                      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 Fund.  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

      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.

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
to other  registered  investment  companies as described in Parts A and B hereof
and listed in Item 28(b) below.

(b) There is set forth below  information as to any other business,  profession,
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

                      OPPENHEIMER FUNDS MULTIPLE CLASS PLAN

                  March 18, 1996 (as updated through 4/27/99)


1.    The Plan.  This Plan is the written  multiple class plan for each of the
open-end  management   investment  companies   (individually  the  "Fund"  and
collectively  the  "Funds")  named on Exhibit A hereto,  which  exhibit may be
revised  from  time to  time,  for  OppenheimerFunds  Distributor,  Inc.  (the
"Distributor"),  the  general  distributor  of  shares  of the  Funds  and for
OppenheimerFunds,  Inc. (the "Advisor"),  the investment advisor of the Funds.
In  instances  where  such  investment  companies  issue  shares  representing
interests  in  different  portfolios  ("Series"),  the term "Fund" and "Funds"
shall  separately  refer to each Series.  It is the written plan  contemplated
by Rule 18f-3  (the  "Rule")  under the  Investment  Company  Act of 1940 (the
"1940  Act"),  pursuant  to which  the Funds may  issue  multiple  classes  of
shares.  The  terms  and  provisions  of this Plan  shall be  interpreted  and
defined in a manner  consistent with the provisions and definitions  contained
in the Rule.
2.    Similarities  and Differences  Among Classes.  Each Fund offering shares
of more than one class agrees that each class of that Fund:  (1)(i) shall have
a separate service plan or distribution  and service plan ("12b-1 Plan"),  and
shall pay all of the expenses incurred pursuant to that arrangement;  and (ii)
may pay a different share of expenses ("Class  Expenses") if such expenses are
actually  incurred  in a  different  amount  by that  class,  or if the  class
receives  services of a different  kind or to a different  degree than that of
other classes.  Class Expenses are those  expenses  specifically  attributable
to the  particular  class of shares,  namely (a) 12b-1 Plan fees, (b) transfer
and  shareholder  servicing  agent fees and  administrative  service fees, (c)
shareholder  meeting  expenses,  (d) SEC registration fees for Funds organized
as  corporations  and  (e)  any  other   incremental   expenses   subsequently
identified  that should be allocated to one class which shall be approved by a
vote of that Fund's Board of Directors,  Trustees or Managing General Partners
(the  "Directors").  Expenses  identified in Items (c) through (e) may involve
issues  relating  either  to a  specific  class or to the  entire  Fund;  such
expenses  constitute  Class  Expenses  only  when they are  attributable  to a
specific  class.  Because Class Expenses may be accrued at different rates for
each class of a single Fund,  dividends  distributable to shareholders and net
asset values per share may differ for shares of different  classes of the same
Fund.
(2) shall have exclusive voting rights on any matters that relate solely to
that class's  arrangements,  including without  limitation voting with respect
to a 12b-1 Plan for that class;
(3) shall have separate voting rights on any matter  submitted to shareholders
in which the  interests  of one class  differ from the  interests of any other
class;
(4) may have a  different  arrangement  for  shareholder  services,  including
different  sales  charges,  sales  charge  waivers,  purchase  and  redemption
features,   exchange   privileges,   loan  privileges,   the  availability  of
certificated shares and/or conversion features; and
(5) shall have in all other  respects the same rights and  obligations as each
other class.
3.    Allocations  of  Income,  Capital  Gains and Losses  and  Expenses.  The
methodologies  and  procedures  for  allocating  expenses,  as  set  forth  in
"Methodology   for  Net  Asset  Value  (NAV)  and  Dividend  and  Distribution
Determinations  for  Oppenheimer  Funds with  Multiple  Classes of Shares" are
re-approved.  Income,  realized and unrealized  capital gains and losses,  and
expenses  of each Fund other than Class  Expenses  allocated  to a  particular
class shall be  allocated to each class on the basis of the net asset value of
that  class in  relation  to the net  asset  value  of that  Fund,  except  as
follows:  For Funds  operating  under 1940 Act Rule 2a-7,  and for other Funds
that declare  dividends  from net  investment  income on a daily  basis,  such
allocations  shall  be made on the  basis  of  relative  net  assets  (settled
shares) [net assets valued in accordance  with generally  accepted  accounting
principles  but excluding the value of  subscriptions  receivable] in relation
to the net assets of that Fund.
4.    Expense  Waivers and  Reimbursements.  From time to time the Advisor may
voluntarily  undertake to (i) waive any portion of the  management fee charged
to a Fund,  and/or (ii)  reimburse any portion of the expenses of a Fund or of
one or more of its classes,  but is not required to do so or to continue to do
so for any  period  of  time.  The  quarterly  report  by the  Advisor  to the
Directors of Fund expense  reimbursements  shall  disclose any  reimbursements
that are not equal for all classes of the same Fund.
5.    Conversions of Shares.  Any Fund may offer a conversion  feature whereby
shares of one class  ("Purchase  Class Shares") will convert  automatically to
shares of another  class  ("Target  Class  Shares") of that Fund,  after being
held for a requisite  period  ("Matured  Purchase Class Shares"),  pursuant to
the terms  and  conditions  of that  Fund's  Prospectus  and/or  Statement  of
Additional  Information.  Upon  conversion of Matured  Purchase  Class Shares,
all Purchase Class Shares of that Fund acquired by  reinvestment  of dividends
or  distributions  of  such  Matured  Purchase  Class  Shares  shall  also  be
converted at that time.  Purchase  Class Shares will convert into Target Class
Shares of that Fund on the basis of the  relative  net asset values of the two
classes,  without the imposition of any sales load,  fee or other charge.  The
conversion  feature  shall be offered for so long as (i) the expenses to which
Target  Class  Shares of a Fund are  subject,  including  payments  authorized
under that Fund's  Target  Class 12b-1 plan,  are not higher than the expenses
of Purchase Class Shares of that Fund,  including  payments  authorized  under
that Fund's  Purchase Class 12b-1 plan; (ii) there continues to be available a
ruling from the Internal  Revenue  Service,  or of an opinion of counsel or of
an opinion of an auditing firm serving as tax adviser,  to the effect that the
conversion  of  Purchase   Class  Shares  to  Target  Class  Shares  does  not
constitute  a  taxable  event  for the  holder;  and  (iii) if the  amount  of
expenses  to  which  Target  Class  Shares  of a Fund are  subject,  including
payments  authorized  under that Fund's  Target Class 12b-1 plan, is increased
materially  without  approval of the  shareholders of Purchase Class Shares of
that Fund,  that Fund will  establish a new class of shares ("New Target Class
Shares")  and shall take such other  action as is  necessary  to provide  that
existing  Purchase  Class Shares are  exchanged  or converted  into New Target
Class  Shares,  identical in all  material  respects to Target Class Shares as
they existed prior to implementation of the proposal to increase expenses,  no
later than the date such shares  previously  were  scheduled  to convert  into
Target Class Shares.
6.    Disclosure.  The  classes of shares to be offered by each Fund,  and the
initial,  asset-based or contingent  deferred sales charges and other material
distribution  arrangements with respect to such classes, shall be disclosed in
the prospectus  and/or statement of additional  information used to offer that
class of shares.  Such  prospectus  or  statement  of  additional  information
shall be  supplemented  or  amended  to reflect  any  change(s)  in classes of
shares  to be  offered  or in  the  material  distribution  arrangements  with
respect to such classes.
7.    Independent  Audit.  The  methodology and procedures for calculating the
net asset value,  dividends and  distributions of each class shall be reviewed
by an  independent  auditing  firm  (the  "Expert").  At least  annually,  the
Expert,  or an  appropriate  substitute  expert,  will  render a report to the
Funds on policies and  procedures  placed in operation  and tests of operating
effectiveness as defined and described in SAS 70 of the AICPA.
8.    Offers and Sales of Shares.  The  Distributor  will maintain  compliance
standards  as to when  each  class  of  shares  may  appropriately  be sold to
particular  investors,  and will  require  all persons  selling  shares of the
Funds to agree to conform to such standards.
9.    Rule 12b-1  Payments.  The  Treasurer of each Fund shall  provide to the
Directors of that Fund, and the Directors  shall review,  at least  quarterly,
the written  report  required by that Fund's  12b-1 Plan,  if any.  The report
shall include  information on (i) the amounts  expended  pursuant to the 12b-1
Plan,  (ii) the purposes for which such  expenditures  were made and (iii) the
amount of the Distributor's  unreimbursed  distribution  costs (if recovery of
such costs in future  periods is permitted  by that 12b-1  Plan),  taking into
account 12b-1 Plan payments and contingent  deferred sales charges paid to the
Distributor.
10.   Conflicts.  On an ongoing basis, the Directors of the Funds, pursuant to
their  fiduciary  responsibilities  under  the  1940 Act and  otherwise,  will
monitor  the Funds  for the  existence  of any  material  conflicts  among the
interests  of  the  classes.   The  Advisor  and  the   Distributor   will  be
responsible  for  reporting  any  potential  or  existing   conflicts  to  the
Directors.  In the event a conflict arises, the Directors shall take such action
as they deem  appropriate.  11.  Effectiveness  and  Amendment.  This Plan takes
effect  for each Fund as of the date of  adoption  shown  below  for that  Fund,
whereupon  the Funds are  released  from the terms and  conditions  contained in
their  respective  exemptive  applications  pursuant to which orders were issued
exempting  the  respective  Funds  from the  provisions  of  Sections  2(a)(32),
2(a)(35),  18(f),  18(g),  18(i), 22(c) and 22(d) of the 1940 Act and Rule 22c-1
thereunder,  or from their respective  previous  multiple class plan.1 This Plan
has been  approved  by a  majority  vote of the  Board of each  Fund and of each
Fund's Board  members who are not  "interested  persons" (as defined in the 1940
Act) and who have no direct or indirect  financial  interest in the operation of
the Plan or any agreements relating to the Plan (the "Independent  Trustees") of
each Fund at  meetings  called for (i) the Denver  Oppenheimer  Funds  listed on
Exhibit A on October 24,  1995,  (ii) the New York  Oppenheimer  Funds listed on
Exhibit A on  October  5,  1995,  (iii) the Quest  Oppenheimer  Funds  listed on
Exhibit A on November 28, 1995, (iv) the Rochester  Oppenheimer  Funds listed on
Exhibit A on January 10, 1996, and (v) the Connecticut  Mutual Oppenheimer Funds
listed in Exhibit A on February 26, 1996, to take effect March 18, 1996, in each
case for the purpose of voting on this Plan.  Prior to that vote, (i) each Board
was  furnished  by the  methodology  used for net asset value and  dividend  and
distribution  determinations  for the Funds, and (ii) majority of each Board and
its  Independent  Trustees  determined  that the Plan as proposed to be adopted,
including  the expense  allocation,  is in the best  interests of each Fund as a
whole  and to each  class  of each  Fund  individually.  Prior  to any  material
amendment  to  the  Plan,  each  Board  shall  request  and  evaluate,  and  the
Distributor  shall furnish,  such information as may be reasonably  necessary to
evaluate  such  amendment,  and a  majority  of each  Board and its  Independent
Trustees  shall find that the Plan as  proposed  to be  amended,  including  the
expense allocation,  is in the best interest of each class, each Fund as a whole
and each class of each Fund  individually.  No  material  amendment  to the Plan
shall be made by any Fund's Prospectus or

and the Fund's  property.  The Distributor  represents that it has notice of the
provisions of the  Declarations of Trust of such Funds  disclaiming  shareholder
and Trustee liability for acts or obligations of the Funds.
