Centennial
California Tax Exempt Trust

   
Prospectus dated October 30, 1998

Centennial  California  Tax Exempt Trust is a no-load "money market" mutual fund
that  seeks  the  maximum  current  interest  income  exempt  from  Federal  and
California personal income taxes for individual  investors as is consistent with
preservation of capital.  The Trust seeks to achieve this objective by investing
in municipal  obligations  meeting specified quality standards,  the income from
which is tax exempt as described above. Normally, the Trust will invest at least
80% of its assets in U.S. dollar-denominated,  high quality tax exempt municipal
obligations.  Shares  of the Trust are sold at net  asset  value  without  sales
charge.  The Trust may  invest a  significant  percentage  of its  assets in the
securities of a single issuer, and therefore an investment in the Trust may be
    
riskier than an investment in other types of money market funds.

      An investment in the Trust is neither  insured nor  guaranteed by the U.S.
Government.  While the Trust seeks to maintain a stable net asset value of $1.00
per share, there can be no assurance that the Trust will be able to do so.

      Shares of the Trust may be  purchased  directly  from  brokers  or dealers
having sales  agreements  with the Trust's  Distributor  and also are offered to
participants  in Automatic  Purchase and  Redemption  Programs (the  "Programs")
established by certain  brokerage  firms with which the Trust's  Distributor has
entered  into  agreements  for  that  purpose.  See "How to Buy  Shares"  in the
Prospectus. Program participants should also read the description of the Program
provided by their broker.

   
      This Prospectus  explains  concisely what you should know before investing
in the  Trust.  Please  read this  Prospectus  carefully  and keep it for future
reference. You can find more detailed information about the Trust in the October
30, 1998 Statement of Additional Information.  For a free copy, call Shareholder
Services,  Inc., the Trust's Transfer Agent, at  1-800-525-9310  or write to the
Transfer  Agent at the address on the back cover.  The  Statement of  Additional
Information  has been filed with the Securities  and Exchange  Commission and is
incorporated  into this Prospectus by reference  (which means that it is legally
part of this Prospectus).

Shares  of the Trust  are not  deposits  or  obligations  of any  bank,  are not
guaranteed by any bank, are not insured by the F.D.I.C. or any other agency, and
involve  investment  risks,  including the possible loss of the principal amount
invested.
    

THESE  SECURITIES  HAVE NOT BEEN APPROVED OR  DISAPPROVED  BY THE SECURITIES AND
EXCHANGE  COMMISSION NOR HAS THE COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY
OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

ABOUT THE TRUST

Expenses

   
The following table sets forth the fees that an investor in the Trust might pay,
and the expenses paid by the Trust during its fiscal year ended June 30, 1998.
    

      o  Shareholder Transaction Expenses

Maximum Sales Charge on Purchases                           None
(as a percentage of offering price)
- - --------------------------------------------------------
Maximum Sales Charge on Reinvested Dividends                None
- - --------------------------------------------------------
Redemption Fee                                              None(1)
- - --------------------------------------------------------
Exchange Fee                                                None

(1) There is a $10 transaction  fee for redemptions  paid by Federal Funds wire,
but not for redemptions paid by check.

       o  Annual Trust Operating Expenses
(as a percentage of average net assets)

   
Management Fees                                             0.50%
    
- - --------------------------------------------------------
12b-1 Plan Fees                                             0.20%
- - --------------------------------------------------------
   
Other Expenses (after expense assumption)                   0.09%
    
- - --------------------------------------------------------
  Total Trust Operating Expenses
   
    (after expense assumption)                              0.79%

      The purpose of this table is to assist an investor  in  understanding  the
various  costs and  expenses  that an investor  in the Trust will bear  directly
(Shareholder   Transaction  Expenses)  or  indirectly  (Annual  Trust  Operating
Expenses).  "Other  Expenses"  includes  such expenses as custodial and transfer
agent fees, audit,  legal and other business  operating  expenses,  but excludes
extraordinary  expenses.  The Annual Trust Operating Expenses shown are net of a
voluntary  expense  assumption  undertaking by the Trust's  investment  manager,
Centennial   Asset  Management   Corporation   (the  "Manager").   Without  such
assumption,  "Other  Expenses" and "Total Trust  Operating  Expenses" would have
been 0.10% and 0.80% of average net assets, respectively. The expense assumption
undertaking is described in "The Manager and Its Affiliates" in the Statement of
Additional  Information and may be withdrawn or amended at any time. For further
details,  see the Trust's  Financial  Statements  included in the  Statement  of
Additional Information.
    
      o Example.  To try to show the effect of these  expenses on an  investment
over time, we have created the hypothetical example shown below. Assume that you
make a $1,000  investment in shares of the Trust,  and the Trust's annual return
is 5%, and that its  operating  expenses  are the ones shown in the Annual Trust
Operating  Expenses chart above. If you were to redeem your shares at the end of
each period shown below,  your investment would incur the following  expenses by
the end of each period shown.

            1 year       3 years       5 years      10 years
            ------       -------       -------      --------
   
            $8           $25           $44          $98
    

      This example  shows the effect of expenses on an  investment in the Trust,
but is not meant to state or  predict  actual or  expected  costs or  investment
returns of the Trust, all of which may be more or less than those shown.

Financial Highlights

   
The table on the following page presents  selected  financial  information about

Investment Objective and Policies

Objective.  The  Trust is a no-load  tax  exempt  money  market  fund.  It is an
open-end,   non-diversified,   management  investment  company  organized  as  a
Massachusetts business trust on August 7, 1989. The Trust's investment objective
is to  seek  the  maximum  current  interest  income  exempt  from  Federal  and
California personal income taxes for individual  investors as is consistent with
preservation of capital.  The Trust's shares may be purchased at their net asset
value, which will remain fixed at $1.00 per share except under
   
extraordinary circumstances.  See "Purchase,  Redemption and Pricing of Shares -
Determination  of Net Asset Value Per Share" and in the  Statement of Additional
Information for further information.  There can be no assurance,  however,  that
the  Trust's  net asset  value will not vary or that the Trust will  achieve its
investment objective.  The value of Trust shares is not insured or guaranteed by
any  government  agency.  However,  shares  held in  brokerage  accounts  may be
eligible for coverage by the  Securities  Investor  Protection  Corporation  for
losses arising from the insolvency of the brokerage firm.

The Trust's Principal Investment Policies.  In seeking its objective,  the Trust
invests  in  short-term  money  market  securities   meeting  quality  standards
established for money market funds in Rule 2a-7 under the Investment Company Act
("Rule  2a-7").  These  securities  are "Eligible  Securities" as defined in the
Statement of Additional Information.

      o What  Quality,  Maturity  and  Diversification  Standards  Apply  to the
Trust's  Investments?  The Trust  may buy only  those  securities  that meet the
quality,  maturity and diversification  standards set forth in the Rule 2a-7 for
money market  funds.  For  example,  the Trust must  maintain a  dollar-weighted
average  portfolio  maturity  of no more  than  90  days.  Some  of the  Trust's
investment restrictions (which are fundamental policies that may be changed only
by shareholder  vote) are more restrictive than these standards.  As a matter of
fundamental policy, the Trust must restrict the maturity of portfolio securities
to one year or less.

     The Board of Trustees has adopted procedures to evaluate securities for the
Trust's  portfolio  and the Manager has the  responsibility  to implement  those
procedures  when  selecting  investments  for  the  Trust.  In  general,   those
procedures  require that securities be payable in U.S.  dollars and rated in one
of  the  two  highest  short-term  rating  categories  of  two  national  rating
organizations.  In some cases,  the Trust can buy securities rated by one rating
organization  or unrated  securities that the Manager judges to be comparable in
quality to the two highest  rating  categories.  The  procedures  also limit the
amount of the Trust's  assets that can be invested in the  securities of any one
issuer (other than the U.S. government, its agencies and instrumentalities),  to
spread the Trust's investment risks.

     o What  Types of Money  Market  Securities  Does the  Trust  Invest  In? In
seeking its objective,  the Trust invests principally in "Municipal  Securities"
as described below.  They may have fixed,  variable or floating  interest rates.
All of the  Trust's  investments  must meet the  special  maturity,  quality and
diversification  requirements set forth in Rule 2a-7.  Investments meeting these
requirements  are called  "Eligible  Securities".  You can find more information
about them in the Statement of Additional Information.  The following is a brief
description of the types of money market securities the Trust may invest in.

      o  Municipal  Securities.  The Trust  invests  in tax  exempt  securities,
consisting of municipal  bonds,  municipal notes (which include tax anticipation
notes, bond anticipation notes,  revenue  anticipation notes,  construction loan
notes and other short-term  loans),  tax exempt  commercial paper and other debt
obligations, which include variable rate demand notes and put bonds issued by or
on  behalf  of the  State of  California,  other  states,  and the  District  of
Columbia, their political subdivisions,  or any commonwealth or territory of the
United States, or their respective  agencies,  instrumentalities or authorities,
the interest from which is not subject to Federal  individual income tax, in the
opinion  of bond  counsel  to the  respective  issuer  (collectively,  these are
referred to as "Municipal Securities"), and in Municipal Securities the interest
from which is not subject to  California  personal  income tax in the opinion of
bond  counsel  to the  respective  issuer  (collectively  "California  Municipal
Securities").  The Trust may also  purchase  Municipal  Securities  with  demand
features that meet the  requirements  of Rule 2a-7 and standards  adopted by the
Board of Trustees.  All  Municipal  Securities  in which the Trust  invests must
have,  or,  pursuant  to  regulations  adopted  by the SEC,  be  deemed to have,
remaining maturities of one year or less at the date the Trust purchases them.

      Under normal market  conditions,  the Trust attempts to invest 100% of its
assets in  Municipal  Securities  and at least 65% of its  assets in  California
Municipal  Securities,  and,  as a  fundamental  policy,  the Trust will make no
investment that will reduce the portion of its total assets that are invested in
Municipal  Securities to less than 80%. The balance of the Trust's assets may be
invested  in  investments  the  income  from  which  may  be  taxable.   Taxable
investments include: (i) repurchase agreements (explained below); (ii) Municipal
Securities  issued to  benefit  a  private  user  ("Private  Activity  Municipal
Securities"),  the  interest  from which may be  subject to Federal  alternative
minimum  tax (see  "Dividends,  Distributions  and  Taxes"  below  and  "Private
Activity Municipal Securities" in the Statement of Additional Information);  and
(iii) certain temporary investments defined below in "Temporary
    
Investments." The Trust may hold Temporary Investments pending the investment of
proceeds  from  the  sale of  Trust  shares  or  portfolio  securities,  pending
settlement of Municipal Securities purchases or to meet anticipated redemptions.
Normally, the Trust will not invest more than 20% of its total assets in Private
Activity Municipal Securities and other taxable investments  described above. No
independent  investigation  has  been  made by the  Manager  as to the  users of
proceeds  of  offerings  of  Private  Activity   Municipal   Securities  or  the
application  of such  proceeds.  To the extent the Trust  receives  income  from
taxable investments, it may not achieve its investment objective.

   
Investment  Strategies.  To seek  its  objective,  the  Trust  may  also use the
investment  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  Floating   Rate/Variable  Rate  Obligations.   Some  of  the  Municipal
Securities 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. 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 the Trust is able to recover the principal amount of
the underlying security at specified intervals not exceeding one year and on not
more than 30 days' notice.  The Manager may determine  that an unrated  floating
rate or variable  rate demand  obligation  meets the Trust's  quality  standards
solely by reason of being backed by a letter of credit or guarantee  issued by a
bank that meets the Trust's quality standards.  However, the letter of credit or
bank guarantee must be rated or meet the other requirements of Rule 2a-7.

      o  When-Issued  or  Delayed-Delivery  Securities.  The Trust may invest in
Municipal  Securities on a "when-issued"  or "delayed  delivery" basis. In those
transactions,  the Trust obligates itself to purchase or sell  securities,  with
delivery and payment to occur at a later date,  to secure what is  considered to
be an  advantageous  price and yield at the time the obligation is entered into.
The price, which is generally expressed in yield terms, is fixed at the time the
commitment  to  purchase is made,  but  delivery  and  payment  for  when-issued
securities  take place at a later date  (normally  within 120 days of purchase).
During the period  between  purchase and  settlement,  no payment is made by the
Trust to the issuer and no  interest  accrues to the Trust from the  investment.
Although the Trust is subject to the risk of adverse market  fluctuation  during
that  period,  the Manager  does not believe that the Trust's net asset value or
income  will  be  materially  adversely  affected  by the  Trust's  purchase  of
Municipal  Securities  on a  "when-issued"  or  "delayed  delivery"  basis.  See
"When-Issued and Delayed  Delivery  Transactions" in the Statement of Additional
Information for more details.
    

      o Municipal  Lease  Obligations.  The Trust may invest in  certificates of
participation, which are tax exempt obligations that evidence the holder's right
to share in lease,  installment  loan or other  financing  payments  by a public
entity.  Projects financed with certificates of participation  generally are not
subject to state constitutional debt limitations or other statutory requirements
that may be applicable to Municipal Securities. Payments by the public entity on
the obligation  underlying the certificates  are derived from available  revenue
sources;  such revenue may be diverted to the funding of other municipal service
projects. Payments of interest and/or principal with respect to the certificates
are not  guaranteed  and do not  constitute an obligation of the state or any of
its political subdivisions.  While some municipal lease securities may be deemed
to be "illiquid" securities (the purchase of which would be limited as described
below in "Illiquid and Restricted Securities"),  from time to time the Trust may
invest more than 5% of its net assets in municipal  lease  obligations  that the
Manager has determined to be liquid under guidelines set by the Trust's Board of
Trustees.

     o 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. The Trust will
not invest more than 10% of its net assets in illiquid or restricted securities.
This policy does not limit purchases of: (1) restricted  securities eligible for
resale to  qualified  institutional  purchasers  pursuant to Rule 144A under the
Securities Act of 1933 that are determined to be liquid by the Board of Trustees
or by the Manager under Board-approved  guidelines, or (2) commercial paper that
may  be  sold  without  registration  under  Sections  3(a)(3)  or  4(2)  of the
Securities Act of 1933. Such  guidelines take into account trading  activity for
such securities and the  availability  of reliable  pricing  information,  among
other factors.  If there is a lack of trading  interest in particular  Rule 144A
Securities,  the Trust's holdings of those securities may be illiquid. If due to
changes in relative value,  more than 10% of the value of the Trust's net assets
consist of illiquid securities,  the Manager would consider appropriate steps to
protect the Trust's  maximum  flexibility.  There may be  undesirable  delays in
selling illiquid securities at prices representing their fair value. The Manager
monitors holdings of
   
illiquid  securities  on an ongoing basis and at times the Trust may be required
to sell some  holdings  to  maintain  adequate  liquidity.  Illiquid  securities
include repurchase agreements maturing in more than seven days.

      o Demand  Features  and  Guarantees.  The Trust may  invest a  significant
percentage  of its assets in  Municipal  Securities  that have demand  features,
guarantees  or  similar  credit and  liquidity  enhancements.  A demand  feature
permits  the holder of the  security  to sell the  security  within a  specified
period of time at a stated  price and  entitles  the holder of the  security  to
receive an amount equal to the  approximate  amortized cost of the security plus
accrued  interest.  A guarantee  permits the holder of the  security to receive,
upon  presentment  to the  guarantor,  the  principal  amount of the  underlying
security  plus accrued  interest  when due or upon  default.  A guarantee is the
unconditional  obligation  of an entity  other than the issuer of the  security.
Demand  features and guarantees can  effectively:  (1) shorten the maturity of a
variable or floating rate security,  (2) enhance the  security's  credit quality
and (3) enhance  the ability to sell the  security.  The  aggregate  price for a
security subject to a demand feature or a guarantee may be higher than the price
that would  otherwise  be paid for the  security  without the  guarantee  or the
demand  feature.  When the Trust purchases  securities  subject to guarantees or
demand features, there is an increase in the cost of the underlying security and
a corresponding  reduction in its yield. Because the Trust invests in securities
backed by banks and other financial institutions,  changes in the credit quality
of these institutions could cause losses to the Trust.  Therefore, an investment
in the Trust may be riskier  than an  investment  in other types of money market
funds.

      o Repurchase Agreements. The Trust may acquire securities that are subject
to  repurchase  agreements to generate  income while  providing  liquidity.  The
Trust's  repurchase  agreements must be fully  collateralized.  However,  if the
seller of the securities  fails to pay the agreed-upon  repurchase  price on the
delivery  date,  the Trust's  risks may include  the costs of  disposing  of the
collateral  for the  agreement  and losses that might  result from any delays in
foreclosing  on the  collateral.  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 and may not enter into
repurchase agreements if the scheduled repurchase date is greater than one year.
Income  earned on  repurchase  transactions  is not tax exempt and  accordingly,
under  normal  market  conditions,  the  Trust  will  limit its  investments  in
repurchase transactions to 20% of its total assets. See Investment Objective and
Policies - Repurchase Agreements" in the Statement of Additional Information for
further details.
    

      o  Temporary  Investments.  The  Trust may hold the  following  "Temporary
Investments" that are Eligible Securities:  (i) obligations issued or guaranteed
by the U.S.  Government  or its  agencies or  instrumentalities;  (ii)  bankers'
acceptances;  (iii) taxable  commercial paper rated in the highest category by a
Rating  Organization;  (iv) short-term  taxable debt obligations rated in one of
the two highest rating categories of a Rating Organization;  or (v) certificates
of  deposit of  domestic  banks  with  assets of $1  billion  or more,  and (vi)
repurchase  agreements.  To the extent the Trust  assumes a temporary  defensive
position,  a significant portion of the Trust's  distributions may be subject to
Federal and California income taxes.

   
Can the Trust's Investment  Objective and Policies Change? The Board of Trustees
may 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.  The  Trust's  investment  policies  and
techniques  are not  fundamental  unless this  Prospectus  or the  Statement  of
Additional Information says that a particular policy is fundamental.
    

Other Investment Restrictions

   
Under some of the Trust's fundamental investment  restrictions,  which cannot be
changed  without the  approval of a majority of the Trust's  outstanding  voting
shares, the Trust cannot:
    

      o make  loans,  except  that  the  Trust,  may  purchase  debt  securities
described  in  "Investment   Objective  and  Policies,"  and  other   securities
substantially similar thereto, and repurchase agreements; and the Trust may lend
its portfolio securities as described in its investment policy stated above;

      o borrow  money in excess of 10% of the value of its total  assets or make
any investment  when borrowings  exceed 5% of the value of its total assets;  it
may borrow only as a temporary measure for extraordinary or emergency  purposes;
no assets of the Trust may be pledged, mortgaged or assigned to secure a debt;

      o enter into a repurchase  agreement  or purchase a security  subject to a
call if the scheduled repurchase or redemption date is greater than one year;

     o invest more than 25% of its total assets in any one industry; however for
the  purposes of this  restriction,  Municipal  Securities  and U.S.  Government
obligations are not considered to be part of any single industry;

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

      o 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.

      Unless the Prospectus states that a percentage  restriction  applies on an
ongoing basis,  it applies only at the time the Trust makes an  investment,  and
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.  Additional
investment  restrictions  are listed in "Other  Investment  Restrictions" in the
Statement of Additional Information.

   
Investment Risks

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 special 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  investment  among issuers to reduce the effects of a default by any one
issuer on the value of the  Trust's  shares.  Even so,  there is a risk that the
Trust's shares could fall below $1.00 per share.

Special  Risk  Considerations  -  California  Municipal  Securities.  The  Trust
concentrates  its investment in securities  issued by the State of California or
entities  within that state,  and  therefore an  investment  in the Trust may be
riskier  than an  investment  in other types of money  market  funds that do not
concentrate their investments in that manner. Because the Trust concentrates its
investments   in  California   Municipal   Securities,   the  market  value  and
marketability of such Municipal  Securities and the interest income to the Trust
from them  could be  adversely  affected  by a  default  or a  financial  crisis
relating to any of such issuers. Investors should consider these matters as well
as economic  trends in  California,  summarized  in the  Statement of Additional
Information  under "Special  Investment  Considerations  - California  Municipal
Securities."

Non-diversification.  The Trust is a "non-diversified"  investment company under
the  Investment  Company Act. As such the  proportion of the Trust's assets that
may be  invested  in the  securities  of a  single  issuer  is not  limited.  An
investment in the Trust will therefore entail greater risk than an investment in
a diversified  investment  company  because a higher  percentage of  investments
among  fewer  issuers may result in greater  credit  risk  exposure to a smaller
number of issuers  and  greater  fluctuation  in the total  market  value of the
Trust's  portfolio.  Economic,  political or regulatory  developments may have a
greater  impact on the value of the Trust's  portfolio than would be the case if
the portfolio were diversified among more issuers.

      However, the Trust is currently subject to other requirements  relating to
the  diversification  of its assets. The Trust intends to conduct its operations
so as to  qualify  as a  "regulated  investment  company"  for  purposes  of the
Internal Revenue Code of 1986, as amended (the "Internal  Revenue Code"),  which
will relieve the Trust from  liability for Federal  income tax to the extent its
earnings  are  distributed  to  shareholders.  Among the  requirements  for such
qualifications  are  that:  (1) not  more  than 25% of the  market  value of the
Trust's total assets will be invested in the securities of a single issuer,  and
(2) with respect to 50% of the market value of its total  assets,  not more than
5% of the market value of its total assets may be invested in the  securities of
a single  issuer  and the Trust  must not own more  than 10% of the  outstanding
voting  securities  of a single  issuer.  In  addition,  the Trust is subject to
certain   diversification   requirements   under  Rule  2a-7.  See   "Investment
Strategies" and "Demand Features and Guarantees."

Year 2000 Risks.  Because  many  computer  software  systems in use today cannot
distinguish  the year 2000 from the year 1900,  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 may incur
substantial  costs in  attempting  to prevent or fix such  errors,  all of which
could have a negative effect on the Trust's investments and returns.

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

Performance of the Trust

Explanation  of  "Yield."  Different  types  of  yields  may be  quoted  to show
performance.  From  time  to  time,  the  "yield,"  "tax-equivalent  yield"  and
"compounded  effective  yield" of an investment in the Trust may be  advertised.
All  yield  figures  are  based on  historical  earnings  per  share and are not
intended to indicate future performance.  The "yield" of the Trust is the income
generated by an investment in the Trust over a seven-day  period,  which is then
"annualized."  In annualizing,  the amount of income generated by the investment
during  that  seven days is  assumed  to be  generated  each week over a 52 week
period,  and is  shown  as a  percentage  of  the  investment.  The  "compounded
effective yield" is calculated similarly, but the annualized income earned by an
investment in the Trust is assumed to be reinvested.  The "compounded  effective
yield" will therefore be slightly higher than the yield because of the effect of
the assumed  reinvestment.  The Trust's "tax- equivalent yield" is calculated by
dividing that portion of the Trust's  "yield"  (calculated  as described  above)
which is tax exempt by one minus a stated  income tax rate and adding the result
to the  portion  (if  any) of the  Trust's  yield  that is not tax  exempt.  The
"tax-equivalent  yield" is then  compounded and annualized in the same manner as
the Trust's yield. See "Performance of the Trust" in the Statement of Additional
Information for further  information on the methods of calculating these yields.
From time to time the  Manager may  voluntarily  assume a portion of the Trust's
expenses (which may include the management  fee),  thereby  lowering the overall
expense  ratio per share and  increasing  the Trust's yield during the time such
expenses are assumed.

How the Trust is Managed

Organization   and   History.   The  Trust's   Board  of  Trustees  has  overall
responsibility  for the management of the Trust under the laws of  Massachusetts
governing the  responsibilities  of trustees of business  trusts.  "Trustees and
Officers" in the  Statement of  Additional  Information  identifies  the Trust's
Trustees  and  officers  and  provides  information  about them.  Subject to the
authority of the Board, the Manager is responsible for the day-to-day management
of the Trust's business,  supervises the investment  operations of the Trust and
the   composition   of  its   portfolio  and  furnishes  the  Trust  advice  and
recommendations  with  respect  to  investments,  investment  policies  and  the
purchase and sale of securities,  pursuant to an Investment  Advisory  Agreement
(the  "Agreement") with the Trust. The Agreement sets forth the fees paid by the
Trust to the Manager and the expenses that the trust is responsible to pay.

     The Trust's shares are of one class, are transferrable  without restriction
and have equal  rights and  privileges.  Each share of the Trust  represents  an
interest in the Trust equal to the interest of each other share in the Trust and
entitles  the  holder  to one  vote  per  share  (and a  fractional  vote  for a
fractional share) on matters submitted to a shareholder vote, and to participate
pro-rata in dividends and distributions  and in the net distributable  assets of
the Trust on  liquidation.  The  Trustees  may divide or combine  shares  into a
greater or lesser number of shares without  thereby  changing the  proportionate
beneficial interest in the Trust. Shares do not have cumulative voting rights or
conversion,  preemptive or subscription rights. The Trust's Board of Trustees is
empowered  to issue  additional  series of shares of the  Trust,  which may have
separate assets and liabilities.

      The Trust will not normally hold annual meetings of the shareholders.  The
Trust may hold shareholder  meetings from time to time on important  matters and
shareholders  have the right to call a meeting to remove a Trustee or take other
action described in the Declaration of Trust.  Although the Declaration of Trust
states that when issued,  shares are fully-paid and nonassessable,  shareholders
may be  held  personally  liable  as  "partners"  for the  Trust's  obligations.
However,  the risk of a shareholder  incurring any financial  loss is limited to
the  relatively  remote  circumstances  in which the Trust is unable to meet its
obligations.  See  "Organization  and History of the Trust" in the  Statement of
Additional Information for details.

   
The Manager and Its  Affiliates.  The  Manager,  a  wholly-owned  subsidiary  of
OppenheimerFunds,  Inc.  ("OFI"),  has operated as an  investment  advisor since
1978. The Manager and OFI currently advise U.S. investment companies with assets
aggregating  over $85 billion as of September  30, 1998,  and having more than 4
million shareholder accounts.  OFI is owned by Oppenheimer  Acquisition Corp., a
holding  company  owned in part by senior  management of OFI and the Manager and
ultimately  controlled by Massachusetts  Mutual Life Insurance Company, a mutual
life  insurance   company  which  also  advises  pension  plans  and  investment
companies.

      The  management  services  provided to the Trust by the  Manager,  and the
services  provided by the  Distributor  and the Transfer Agent to  shareholders,
depend on the  smooth  functioning  of their  computer  systems.  Many  computer
software  systems in use today  cannot  distinguish  the year 2000 from the year
1900 because of the way dates are encoded and  calculated.  That  failure  could
have a negative  impact on handling  securities  trades,  pricing and accounting
services.  The Manager,  the  Distributor  and Transfer Agent have been actively
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,  because  the
services they provide depend on the  interaction of their computer  systems with
the computer  systems of brokers,  information  services and other parties,  any
failure on the part of the computer  systems of those third parties to deal with
the year 2000 may also have a negative  effect on the  services  provided to the
Trust.
    

      o Fees and Expenses.  The Trust's  management fee,  payable monthly to the
Manager under the terms of the Agreement,  is computed on the average annual net
assets as of the close of business each day at the following annual rates: 0.50%
of the first $250 million of net assets;  0.475% of the next $250 million of net
assets;  0.45% of the next $250  million of net assets;  0.425% of the next $250
million of net assets and 0.40% of net assets in excess of $1 billion.

      The  Agreement  lists  examples of expenses  paid by the Trust,  the major
categories of which relate to interest,  taxes, brokerage  commissions,  certain
insurance premiums, fees to certain Trustees, legal and audit expenses, transfer
agent and custodian expenses,  certain  registration  expenses and non-recurring
expenses,   including  litigation  costs.  For  further  information  about  the
Agreement,  including a description of expense  assumption  arrangements  by the
Manager, exculpation provisions and portfolio transactions, see "The Manager and
Its Affiliates" in the Statement of Additional Information.

     o The Custodian. The Custodian of the assets of the Trust is Citibank, N.A.
The Manager and its  affiliates  presently have banking  relationships  with the
Custodian.  See "The Manager and Its  Affiliates" in the Statement of Additional
Information  for further  information.  The Trust's  cash  balances in excess of
$100,000 held by the Custodian are not protected by Federal  deposit  insurance.
Such uninsured balances may at times be substantial. The rating
   
restrictions under Rule 2a-7 (see "Ratings of Securities  -Portfolio Quality and
Diversification"  in the Statement of Additional  Information.)  do not apply to
banks in which the Trust's cash is kept.
    

      o Transfer Agent. Shareholder Services, Inc., a subsidiary of OFI, acts as
Transfer Agent and shareholder servicing agent on an at-cost basis for the Trust
and other mutual funds advised by the Manager. The fees to the Transfer Agent do
not include  payments for any services of the type paid,  or to be paid,  by the
Trust to the Distributor and to Recipients  under the Service Plan (see "Service
Plan" below).  Direct  Shareholders  should  direct any inquiries  regarding the
Trust to the Transfer Agent at the address or toll-free phone number on the back
cover.  Program  participants should direct any inquiries regarding the Trust to
their broker.

ABOUT YOUR ACCOUNT

How To Buy Shares

   
Shares of the Trust may be purchased at their offering  price,  which is the net
asset value per share,  without  sales  charge.  The net asset value will remain
fixed  at  $1.00  per  share,  except  under  extraordinary  circumstances.  See
"Purchase,  Redemption and Pricing of Shares - Determination  of Net Asset Value
Per Share" in the Statement of Additional Information for further details. There
can be no  guarantee  that the Trust will  maintain a stable net asset  value of
$1.00 per share. Centennial Asset Management Corporation, which also acts as the
Trust's  distributor (and in that capacity is referred to as the "Distributor"),
may in its sole  discretion  accept or reject  any  order  for  purchase  of the
Trust's  shares.   OppenheimerFunds  Distributor,  Inc.,  an  affiliate  of  the
Distributor, acts as the Trust's sub-distributor (the "Sub- Distributor").
    

     The minimum  initial  investment is $500 ($2,500 if by Federal Funds wire),
except as otherwise described in this Prospectus.  Subsequent  purchases must be
in amounts of $25 or more, and may be made through authorized dealers or brokers
or by forwarding payment to the Distributor at P.O. Box 5143,  Denver,  Colorado
80217,  with the name(s) of all account owners,  the account number and the name
of the Trust.  The minimum  initial and  subsequent  purchase  requirements  are
waived on purchases  made by  reinvesting  dividends  from any of the  "Eligible
Funds" listed in "Exchange of Shares" in the Statement of Additional Information
or  by  reinvesting   distributions   from  unit  investment  trusts  for  which
reinvestment  arrangements  have  been  made  with  the  Distributor.  Under  an
Automatic  Investment Plan, military allotment plan, 403(b)(7) custodial plan or
payroll deduction plan, initial and subsequent investments must be at least $25.
No share certificates will be issued unless specifically requested in writing by
an investor or the dealer or broker.

      The Trust intends to be as fully  invested as  practicable to maximize its
yield.  Therefore,  dividends will accrue on newly-  purchased shares only after
the Distributor  accepts the purchase order for them at its address in Colorado,
on a day The New York Stock  Exchange is open (a "regular  business  day") under
one of the methods of purchasing  shares  described  below. The purchase will be
made at the net asset value next determined  after the  Distributor  accepts the
purchase order.

   
      The  Trust's net asset value per share is  determined  twice each  regular
business  day, at 12:00 Noon and at 4:00 P.M.  (all  references  to time in this
Prospectus  mean New York time) by  dividing  the net assets of the Trust by the
total  number of its shares  outstanding.  The  Trust's  Board of  Trustees  has
established  procedures for valuing the Trust's assets, using the amortized cost
method,  as  described  in  "Determination  of Net Asset Value Per Share" in the
Statement of Additional Information.

      Dealers and brokers who process orders for the Trust's shares on behalf of
their  customers may charge a fee for this  service.  That fee can be avoided by
Direct   shareholders  by  purchasing   shares  directly  from  the  Trust.  The
Distributor,  in its sole  discretion,  may  accept  or  reject  any  order  for
purchases of the Trust's shares. The sale of shares will be suspended during any
period  when the  determination  of net  asset  value is  suspended,  and may be
suspended  by the Board of  Trustees  whenever  the Board  judges it in the best
interest of the Trust to do so.
    

Purchases  Through  Automatic  Purchase and Redemption  Programs.  Shares of the
Trust  are  available   under   Automatic   Purchase  and  Redemption   Programs
("Programs")  of  broker-dealers  that have  entered  into  agreements  with the
Distributor for that purpose.  Broker-dealers  whose clients participate in such
Programs will invest the "free cash balances" of such client's  Program  account
in shares of the Trust if the Trust has been  selected as the  primary  Trust by
the  client  for  the  Program  account.  Such  purchases  will  be  made by the
broker-dealer under the procedures described in "Guaranteed Payment," below. The
Program  may  have   minimum   investment   requirements   established   by  the
broker-dealer.  The  description  of the Program  provided by the  broker-dealer
should  be  consulted  for  details,  and  all  questions  about  investing  in,
exchanging or redeeming shares of the Trust through a Program should be directed
to the broker-dealer.

Direct Purchases.  An investor (who is not a Program participant,  but instead a
"Direct  Shareholder")  may directly  purchase  shares of the Trust  through any
dealer which has a sales agreement with the Distributor or the  Sub-Distributor.
There are two ways to make a direct  initial  investment:  either (1) complete a
Centennial  Funds  New  Account  Application  and  mail it with  payment  to the
Distributor at P.O. Box 5143, Denver, Colorado 80217-5143 (if no dealer is named
in the Application,  the  Sub-Distributor  will act as the dealer), or (2) order
the shares through your dealer or broker.  Purchases made by Application  should
have a check enclosed,  or payment may be made by one of the  alternative  means
described below.

      o Payment by Check.  Orders for shares  purchased by check in U.S. dollars
drawn on a U.S.  bank will be effected on the regular  business day on which the
check (and a purchase  application,  if the  account is new) is  accepted by the
Distributor.  Dividends  will begin to accrue on such  shares  the next  regular
business day after the purchase order is accepted.  For other checks, the shares
will not be  purchased  until the  Distributor  is able to convert the  purchase
payment to Federal  Funds,  and dividends will begin to accrue on such shares on
the next regular business day.

     o Payment by Federal  Funds Wire.  Shares of the Trust may be  purchased by
Direct  Shareholders  by Federal Funds wire.  The minimum  investment by wire is
$2,500.  You must first call the Distributor's Wire Department at 1-800-852-8457
to notify the Distributor of the wire and to receive further  instructions.  The
investor's  bank  must  wire  the  Federal  Funds  to  Citibank,  N.A.,  ABA No.
0210-0008-9  for credit to  Concentration  Account  No.  3737-5674,  for further
credit to Centennial California Tax Exempt Trust, Custodian Account No. 845-873.

   
      The wire must state the investor's  name.  Shares will be purchased on the
regular  business day on which the Federal Funds are received by Citibank,  N.A.
("Custodian")  and the  Distributor  has received  and  accepted the  investor's
notification  of the wire order prior to 4:00 P.M.  Shares will be  purchased at
the net asset value next  determined  after receipt of the Federal Funds and the
order.  Dividends on newly purchased shares will begin to accrue on the purchase
date if the Federal  Funds and order for the  purchase are received and accepted
by 12:00 Noon.  Dividends will begin to accrue on the next regular  business day
if the Federal Funds and purchase order are received and accepted  between 12:00
Noon and 4:00 P.M.  The  investor  must also send the  Distributor  a  completed
Application when the purchase order is placed to establish a new account.

      o  Guaranteed  Payment.  Broker-dealers  with  sales  agreements  with the
Distributor  (including  broker-dealers who have made special  arrangements with
the  Distributor  for purchases for Program  accounts) may place purchase orders
with the  Distributor for purchases of the Trust's shares prior to 12:00 Noon on
a regular  business  day,  and the order  will be  effected  at net asset  value
determined at 12:00 Noon that day if the  broker-dealer  guarantees that payment
for such shares in Federal Funds will be received by the Trust's Custodian prior
to 2:00 P.M.  on the same day.  Dividends  will begin to accrue on the  purchase
date. If an order is received  between 12:00 Noon and 4:00 P.M. with the broker-
dealer's  guarantee  that  payment  for such  shares in  Federal  Funds  will be
received by the Trust's Custodian by 4:00 P.M. on the next regular business day,
the order will be effected on the day the order is  received,  and  dividends on
such shares will begin to accrue on the next  regular  business  day the Federal
Funds are received by the required time. If the  broker-dealer  guarantees  that
the Federal Funds payment will be received by the Trust's Custodian by 2:00 P.M.
on a regular  business  day on which an order is placed for shares  after  12:00
Noon,  the order will be effected at 4:00 P.M. that day and dividends will begin
to accrue on such shares on the purchase date.

      o Automatic  Investment Plans.  Direct shareholders may purchase shares of
the Trust automatically.  Automatic Investment Plans may be used to make regular
monthly investments ($25 minimum) from the investor's account at a bank or other
financial  institution.  To establish an Automatic  Investment  Plan from a bank
account,  a check  (minimum  $25) for the initial  purchase  must  accompany the
Application.  Shares purchased by Automatic Investment Plan payments are subject
to the redemption  restrictions for recent  purchases  described in "How to Sell
Shares." The amount of the Automatic  Investment  Plan payment may be changed or
the  automatic  investments  may be  terminated  at any time by  writing  to the
Transfer Agent. A reasonable  period  (approximately  15 days) is required after
receipt of such  instructions to implement them. The Trust reserves the right to
amend,  suspend, or discontinue  offering such Automatic Investment Plans at any
time without prior notice.
    

Service Plan. The Trust has adopted a service plan (the "Plan") under Rule 12b-1
of the  Investment  Company Act pursuant to which the Trust will  reimburse  the
Distributor  for a portion of its costs incurred in connection with the personal
service and maintenance of accounts that hold Trust shares. The Distributor will
use all the fees received from the Trust to reimburse dealers,  brokers,  banks,
or other  financial  institutions  ("Recipients")  each  quarter  for  providing
personal  service  and  maintenance  of  accounts  that hold Trust  shares.  The
services to be provided by Recipients  under the Plan include,  but shall not be
limited to, the following:  answering  routine  inquiries  from the  Recipient's
customers  concerning the Trust,  providing  such customers with  information on
their investment in Trust shares, assisting in the establishment and maintenance
of accounts or sub-accounts in the Trust,  making the Trust's  investment  plans
and dividend payment options available, and providing such other information and
customer  liaison services and the maintenance of accounts as the Distributor or
the Trust may reasonably request.  Plan payments by the Trust to the Distributor
will be made  quarterly  in the  amount  of the  lesser  of:  (i)  0.05%  (0.20%
annually) of the net asset value of the Trust,  computed as of the close of each
business day, or (ii) the Distributor's  actual  distribution  expenses for that
quarter of the type approved by the Board.  Any unreimbursed  expenses  incurred
for any quarter by the  Distributor  may not be recovered in later periods.  The
Plan has the effect of increasing annual expenses of the Trust by up to 0.20% of
average  annual  net  assets  from  what its  expenses  would  otherwise  be. In
addition,  the  Manager  may,  under  the  Plan,  from time to time from its own
resources  (which may include  the  profits  derived  from the  advisory  fee it
receives  from  the  Trust),  make  payments  to  Recipients  for  distribution,
administrative  and accounting  services  performed by  Recipients.  For further
details, see "Service Plan" in the Statement of Additional Information.

How to Sell Shares

Program Participants.  A Program participant may redeem shares in the Program by
writing  checks as described  below,  or by contacting  the dealer or broker.  A
program  participant may also arrange for "Expedited  Redemptions," as described
below, only through his or her dealer or broker.

Direct  Shareholders.  Those shareholders whose ownership of shares of the Trust
is direct  rather than through a Program,  may redeem  shares by either  regular
redemption procedures or by expedited redemption procedures.

      o Regular Redemption Procedure.  A Direct Shareholder who wishes to redeem
some or all shares in an account  (whether or not  represented by  certificates)
under the Trust's regular redemption  procedure,  must send the following to the
Transfer Agent for the Trust, Shareholder Services, Inc., P.O. Box 5143, Denver,
Colorado  80217  [send  courier or express  mail  deliveries  to 10200 E. Girard
Avenue,  Building  D,  Denver,  Colorado  80231]:  (1)  a  written  request  for
redemption signed by all registered owners exactly as the shares are registered,
including  fiduciary  titles,  if any, and specifying the account number and the
dollar  amount  or  number of shares  to be  redeemed;  (2) a  guarantee  of the
signatures  of  all  registered  owners  on  the  redemption  request  or on the
endorsement on the share  certificate  or  accompanying  stock power,  by a U.S.
bank,  trust  company,  credit union or savings  association,  or a foreign bank
having 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,  registered securities  association or clearing agency; (3)
any share certificates issued for any of the shares to be redeemed;  and (4) any
additional  documents which may be required by the Transfer Agent for redemption
by corporations, partnerships or other organizations, executors, administrators,
trustees,  custodians or guardians,  or if the redemption is requested by anyone
other than the  shareholder(s)  of record.  Transfers  of shares are  subject to
similar  requirements.  A signature guarantee is not required for redemptions of
$50,000 or less,  requested by and payable to all shareholders of record,  to be
sent to the address of record for that account.  To avoid delay in redemption or
transfer,  shareholders having questions about these requirements should contact
the Transfer Agent in writing or by calling  1-800-525-9310  before submitting a
request. From time to time the Transfer Agent in its discretion may waive any or
certain  of the  foregoing  requirements  in  particular  cases.  Redemption  or
transfer  requests  will not be honored  until the Transfer  Agent  receives all
required documents in proper form.

   
      o Expedited  Redemption  Procedure.  In addition to the regular redemption
procedure set forth above,  Direct Shareholders whose shares are not represented
by certificates may arrange to have redemption  proceeds of $2,500 or more wired
in Federal Funds to a designated  commercial bank if the bank is a member of the
Federal  Reserve  wire  system.  To place a wire  redemption  request,  call the
Transfer  Agent at  1-800-852-8457.  There is a $10 fee for each  Federal  Funds
wire. The account number of the designated  financial  institution  and the bank
ABA number must be supplied to the Transfer  Agent on the  Application or dealer
settlement  instructions  establishing  the  account or may be added to existing
accounts or changed only by  signature-guaranteed  instructions  to the Transfer
Agent from all shareholders of record.  Such redemption  requests may be made by
telephone,  wire or written instructions to the Transfer Agent. The wire for the
redemption  proceeds of shares  redeemed  prior to 12:00 Noon,  normally will be
transmitted by the Transfer Agent to the  shareholder's  designated bank account
on the day the shares are redeemed  (or, if that day is not a bank business day,
on the next  bank  business  day).  No  dividends  are paid on the  proceeds  of
redeemed  shares  awaiting  transmittal by wire.  Shares redeemed prior to 12:00
Noon do not earn dividends on the  redemption  date. The wire for the redemption
proceeds of shares  redeemed  between 12:00 Noon and 4:00 P.M.  normally will be
transmitted by the Transfer Agent to the  shareholder's  designated bank account
on the next bank  business day after the  redemption.  Shares  redeemed  between
12:00 Noon and 4:00 P.M. earn dividends on the  redemption  date. See "Purchase,
Redemption and Pricing of Shares" in the Statement of Additional Information for
further details.
    

      o Checkwriting.  Upon request,  the Transfer Agent will provide any Direct
Shareholder  of the  Trust  or any  Program  participant  whose  shares  are not
represented by certificates  with forms of drafts  ("checks")  payable through a
bank selected by the Trust (the "Bank").  Program  participants must arrange for
Checkwriting  through their brokers or dealers.  The Transfer Agent will arrange
for  checks  written  by Direct  Shareholders  to be  honored  by the Bank after
obtaining a specimen  signature card from the  shareholder(s).  Shareholders  of
joint accounts may elect to have checks honored with a single signature. Program
participants  must  arrange for  Checkwriting  through  their  broker or dealer.
Checks  may be made  payable  to the order of anyone in any amount not less than
$250 and will be subject to the Bank's rules and regulations  governing  checks.
If a check is presented for an amount  greater than the account  value,  it will
not be honored.  For  Program  participants,  checks  will be drawn  against the
primary  account  designated by the Program  participant.  Checks issued for one
Fund account must not be used if the shareholder's  account has been transferred
to a new  account or if the account  number or  registration  has been  changed.
Shares purchased by check or Automatic Investment Plan payments within the prior
10 days may not be redeemed by  Checkwriting.  A check presented to the Bank for
payment that would require  redemption of some or all of the shares so purchased
is subject to non-payment.  When a check is presented to the Bank for clearance,
the Bank  will  request  the  Trust to  redeem a  sufficient  number of full and
fractional shares in the shareholder's account to cover the amount of the check.
This enables the  shareholders  to continue  received  dividends on those shares
until the check is presented to the Trust.  Checks may not be presented for cash
payment at the offices of the Bank or the  Trust's  Custodian.  This  limitation
does not affect the use of checks for the  payment of bills or to obtain cash at
other  banks.  The Trust  reserves  the right to amend,  suspend or  discontinue
Checkwriting privileges at any time without prior notice.

      o Telephone Redemptions. Direct Shareholders of the Trust may redeem their
shares by  telephone  by calling  the  Transfer  Agent at  1-800-852-8457.  This
procedure for telephone  redemptions  is not available to Program  participants.
Proceeds  of  telephone  redemptions  will  be  paid  by  check  payable  to the
shareholder(s)  of record and sent to the  address  of record  for the  account.
Telephone  redemptions  are not  available  within  30 days of a  change  of the
address of record.  Up to $50,000  may be redeemed  by  telephone,  in any 7 day
period. The Transfer Agent may record any calls.  Telephone  redemptions may not
be  available  if all lines are busy,  and  shareholders  would  have to use the
Trust's regular  redemption  procedure  described  above.  Telephone  redemption
privileges  are not  available  for  newly-purchased  (within the prior 10 days)
shares  or  for  shares  represented  by  certificates.   Telephone   redemption
privileges  apply  automatically  to each  Direct  Shareholder  and  the  dealer
representative  of  record  unless  the  Transfer  Agent  receives  cancellation
instructions  from a shareholder of record.  If an account has multiple  owners,
the Transfer Agent may rely on the instructions of any one owner.

   
      o  Automatic  Withdrawal  Plan.  Direct  Shareholders  of  the  Trust  can
authorize the Transfer Agent to redeem shares (minimum $50)  automatically  on a
monthly,  quarterly,  semi-annual or annual basis under an Automatic  Withdrawal
Plan.  Shares  will be redeemed as of the close 4:00 P.M.  three  business  days
prior to the date requested by the shareholder  for receipt of the payment.  The
Trust cannot guarantee receipt of payment on the date requested and reserves the
right to amend,  discontinue  or cease  offering  such plans at any time without
prior  notice.  For  further  details,   see  the  "Automatic   Withdrawal  Plan
Provisions" included as Appendix D in the Statement of Additional Information.
    

General  Information on Redemptions.  The redemption price will be the net asset
value per share of the Trust next  determined  after the receipt by the Transfer
Agent of a request in proper form.
Under  certain  unusual  circumstances,  shares of the Trust may be redeemed "in
kind" (i.e., by payment in portfolio  securities).  Under certain circumstances,
the Trust may  involuntarily  redeem  small  accounts  if the account has fallen
below $200 in value.  For  details,  see  "Purchase,  Redemption  and Pricing of
Shares" in the Statement of Additional  Information.  Under the Internal Revenue
Code, the Trust may be required to impose "backup" withholding of Federal income
tax  at  the  rate  of  31%  from  any  taxable  dividends,   distributions  and
redemptions(including  exchanges) the Trust may make, if the shareholder has not
furnished the Trust a certified
taxpayer  identification  number or has not complied with the  provisions of the
Internal Revenue Code and regulations thereunder.

     Payment for redeemed shares is made ordinarily in cash and forwarded within
7 days of the Transfer  Agent's  receipt of  redemption  instructions  in proper
form,  except under unusual  circumstances  as determined by the  Securities and
Exchange  Commission.  For accounts  registered in the name of a broker- dealer,
payment will be forwarded  within 3 business  days. The Transfer Agent may delay
forwarding  a  redemption  check for  recently  purchased  shares only until the
purchase check has cleared, which may take up to 10 days or more. Such delay may
be  avoided  if  the  shareholder   arranges   telephone  or  written  assurance
satisfactory  to the Transfer Agent from the bank on which the payment was drawn
or by purchasing  shares by Federal Funds wire,  as described  above.  The Trust
makes no charge for redemption. Dealers or brokers may charge a fee for handling
redemption  transactions,  but such fee can be avoided by Direct Shareholders by
requesting the redemption  directly  through the Transfer  Agent.  Under certain
circumstances,  the proceeds of  redemptions  of shares of the Trust acquired by
exchange  of Class A shares of  "Eligible  Funds"  (described  below)  that were
purchased subject to a contingent  deferred sales charge ("CDSC") may be subject
to the CDSC (see "Exchange Privilege" below).

Exchanges of Shares

Exchange  Privilege.  Shares of the Trust held under a Program may be  exchanged
for shares of Centennial Money Market Trust,
   
Centennial  Government  Trust,  Centennial Tax Exempt Trust,  and Centennial New
York Tax Exempt Trust  (collectively,  the "Centennial Trusts") if available for
sale in the  shareholder's  state of residence and only by  instructions  of the
broker.
    

     Shares of the Trust may, under certain  conditions,  be exchanged by Direct
Shareholders  for Class A shares of  certain  Oppenheimer  funds.  A list of the
Oppenheimer funds currently  available for exchange is included in the Statement
of Additional  Information.  That list can change from time to time.  (The funds
included on the list are collectively referred to as "Eligible Funds"). There is
an initial  sales charge on the purchase of Class A shares of each Eligible Fund
except  the Money  Market  Funds (as  defined  in the  Statement  of  Additional
Information).  Under certain circumstances  described below, redemption proceeds
of Money Market Fund shares may be subject to a CDSC.

      Shares of the Trust and of the other  Eligible  Funds may be  exchanged at
net asset value,  if all of the following  conditions are met: (1) shares of the
fund selected for exchange are available for sale in the shareholder's  state of
residence; (2) the respective prospectuses of the funds whose shares are to be
exchanged  and  acquired  offer the  Exchange  Privilege  to the  investor;  (3)
newly-purchased  shares (by  initial or  subsequent  investment)  are held in an
account for at least seven days prior to the exchange; and (4) the aggregate net
asset  value of the shares  surrendered  for  exchange  into a new account is at
least equal to the minimum investment  requirements of the fund whose shares are
to be acquired.

   
      In addition to the conditions  stated above,  shares of Eligible Funds may
be exchanged  for shares of any Money  Market  Fund;  shares of any Money Market
Fund held by Direct Shareholders (including the Trust) purchased without a sales
charge may be exchanged for shares of Eligible Funds offered with a sales charge
upon  payment of the sales  charge (or, if  applicable,  may be used to purchase
shares of Eligible Funds subject to a CDSC); and shares of the Trust acquired by
reinvestment  of dividends  and  distributions  from any Eligible  Fund,  except
Oppenheimer  Cash  Reserves,  or  from  any  unit  investment  trust  for  which
reinvestment arrangements have been made with the Distributor or Sub-Distributor
may be  exchanged  at net asset  value  for  shares of any  Eligible  Fund.  The
redemption  proceeds  of shares of the Trust,  acquired  by  exchange of Class A
shares of an Eligible  Fund  purchased  subject to a Class A CDSC,  and redeemed
within 18 months of the end of the calendar month of the initial purchase of the
exchanged  shares,  will be  subject  to the  Class A CDSC as  described  in the
prospectus  of that other  Eligible  Fund.  In  determining  whether the CDSC is
payable,  shares  of the  Trust  not  subject  to the CDSC are  redeemed  first,
including  shares  purchased  by  reinvestment  of dividends  and capital  gains
distributions from any Eligible Fund or shares of the Trust acquired by exchange
of  shares of  Eligible  Funds on which a  front-end  sales  charge  was paid or
credited, and then other shares are redeemed in the order of purchase.

How to Exchange  Shares.  An  exchange  may be made by a Direct  Shareholder  by
submitting an Exchange  Authorization Form to the Transfer Agent,  signed by all
registered  owners. In addition,  Direct  Shareholders of the Trust may exchange
shares of the  Trust  for  shares of any  Eligible  Fund by  telephone  exchange
instructions to the Transfer Agent by a shareholder or the dealer representative
of record for an account.  The Trust may  modify,  suspend or  discontinue  this
exchange  privilege  at any time.  Although  the Trust  will  attempt to provide
notice  whenever it is reasonably  able to do so, it may impose these changes at
any time. The Trust reserves the right to reject  requests  submitted in bulk on
behalf of more than one account.  Exchange  requests for exchanges to any of the
Centennial  Trusts  must be received  by the  Transfer  Agent by 4:00 P.M. to be
effected that day.  Exchange requests for exchanges to Eligible Funds other than
the Centennial Trusts must be received by the Transfer Agent by the close of The
New York Stock  Exchange on a regular  business day to be effected that day. The
number of shares  exchanged may be less than the number  requested if the number
requested  would include shares  subject to a restriction  cited above or shares
covered by a certificate that is not tendered with such request. Only the shares
available for exchange without restriction will be exchanged.
    

Telephone Exchanges.  Direct Shareholders may place a telephone exchange request
by calling the Transfer Agent at 1-800-852-8457. Telephone exchange calls may be
recorded by the Transfer  Agent.  Telephone  exchanges  are subject to the rules
described  above.  By  exchanging  shares  by  telephone,   the  shareholder  is
acknowledging  receipt of a prospectus of the fund to which the exchange is made
and that for full or partial  exchanges,  any special  account  features such as
Automatic  Investment  Plans and Automatic  Withdrawal Plans will be switched to
the new account  unless the Transfer  Agent is otherwise  instructed.  Telephone
exchange privileges automatically apply to each Direct Shareholder of record and
the dealer representative of record unless and until the Transfer Agent receives
written instructions from a shareholder of record canceling such privileges.  If
an account has multiple owners,  the Transfer Agent may rely on the instructions
of any one owner.  Shares  acquired by  telephone  exchange  must be  registered
exactly as the account from which the exchange was made. Certificated shares are
not eligible for telephone  exchange.  If all telephone  exchange lines are busy
(which  might  occur,  for  example,   during  periods  of  substantial   market
fluctuations), shareholders might not be able to request telephone exchanges and
would have to submit written exchange requests.

   
Telephone  Instructions.  The Transfer Agent has adopted  procedures  concerning
telephone  transactions  including  confirming that telephone  instructions  are
genuine by requiring callers to provide tax  identification  number(s) and other
account  data or by using  PINS,  and by  recording  calls and  confirming  such
transactions  in  writing.  If  the  Transfer  Agent  does  not  use  reasonable
procedures,  it may be liable for losses due to unauthorized  transactions,  but
otherwise neither it nor the Trust will be liable for losses or expenses arising
out of any  telephone  instructions  it reasonably  believed to be genuine.  The
Transfer  Agent  reserves  the right to  require  shareholders  to  confirm,  in
writing, telephone exchange privileges for an account.

General Information on Exchanges. Shares to be exchanged are redeemed on the day
the Transfer Agent receives an exchange  request in proper form (the "Redemption
Date")by 4:00 P.M. Normally,
    
shares of the fund to be acquired are purchased on the Redemption Date, but such
purchases  may be  delayed  by either  fund for up to five  business  days if it
determines  that it would  be  disadvantaged  by an  immediate  transfer  of the
redemption  proceeds.  The Trust in its discretion  reserves the right to refuse
any exchange request that will disadvantage it.

     The Eligible Funds have different investment objectives and policies.  Each
of those funds except the Money Market Funds imposes a sales charge on purchases
of Class A  shares.  For  complete  information,  including  sales  charges  and
expenses,  a prospectus of the fund into which the exchange is being made should
be read prior to an exchange. Dealers and brokers who process exchange orders on
behalf of customers may charge for their services. Direct Shareholders may avoid
those charges by requesting the Trust directly to exchange  shares.  For Federal
tax purposes, an exchange is treated as a redemption and purchase of shares.

   
Shareholder  Transactions by Fax. Requests for certain account  transactions may
be sent to the Transfer Agent by fax  (telecopier).  Please call  1-800-525-9310
for information  about which  transactions  are included.  Transaction  requests
submitted by fax are subject to the same rules and  restrictions  as written and
telephone requests described in this Prospectus.
    


Dividends, Distributions and Taxes

   
This discussion  relates solely to Federal income tax laws and California income
tax laws and is not exhaustive.  A qualified tax advisor should be consulted.  A
portion of the Trust's  dividends and  distributions  may be subject to federal,
state and local  taxation.  The  Statement of  Additional  Information  contains
further discussion of tax matters affecting the Trust and its distributions, and
information about the possible  applicability of the Alternative  Minimum Tax to
the Trust's  dividends and  distributions as well as a procedure for electing to
reinvest dividends and distributions of any of the Eligible Funds into shares of
the Trust at net asset value. (See "Investment  Objective and Policies - Private
Activity Municipal Securities" in the Statement of Additional Information).
    

Dividends and Distributions. The Trust intends to declare all of its net income,
as defined below, as dividends on each regular business day and to pay dividends
monthly.  Dividends will be payable to  shareholders as described in "How to Buy
Shares" above.

      All dividends and capital gains  distributions for the accounts of Program
participants  are  automatically  reinvested in additional  shares of the Trust.
Dividends  accumulated  since the prior  payment will be  reinvested in full and
fractional shares of the Trust (or paid in cash) at net asset value on the third
Thursday of each calendar month.  Program participants may receive cash payments
by asking the broker to redeem shares.  Dividends and  distributions  payable to
Direct Shareholders will also be automatically reinvested in shares of the Trust
at net asset value, unless the shareholder asks the Transfer Agent in writing to
pay  dividends  in cash,  or to  reinvest  them in  another  Eligible  Fund,  as
described in
   
"Dividend   Reinvestment  in  Another  Fund"  in  the  Statement  of  Additional
Information.  That notice must be received prior to a dividend record date to be
effective as to that dividend.  If a shareholder  redeems all shares at any time
during a month, the redemption  proceeds include all the dividends accrued up to
the  redemption  date for shares  redeemed  prior to 12:00 Noon, and include all
dividends  accrued through the redemption date for shares redeemed between 12:00
Noon and 4:00 P.M.  Dividends,  distributions and the proceeds of redemptions of
Trust shares  represented by checks returned to the Transfer Agent by the Postal
Service as undeliverable  will be reinvested in shares of the Trust, as promptly
as possible after the return of such checks to the Transfer Agent, to enable the
investor to earn a return on otherwise idle funds.
    

      Under the terms of a  Program,  a  broker-dealer  may pay out the value of
some or all of a Program  participant's Trust shares prior to redemption of such
shares  by the  Trust.  In such  cases,  the  shareholder  will be  entitled  to
dividends  on such shares  only up to and  including  the date of such  payment.
Dividends on such shares accruing  between the date of payment and the date such
shares  are  redeemed  by the Trust will be paid to the  broker-dealer.  Program
participants should discuss these arrangements with their broker-dealer.

      The Trust's net investment  income for dividend  purposes  consists of all
interest  accrued on portfolio  assets,  less all expenses of the Trust for such
period.  Distributions  from net realized gains on  securities,  if any, will be
paid at least once each year, and may be made more frequently in compliance with
the  Internal  Revenue  Code and the  Investment  Company  Act. Any net realized
capital loss is carried  forward to offset against capital gains in later years.
The Trust will not make any  distributions  from net realized  securities  gains
unless  capital loss carry  forwards,  if any,  have been used or have  expired.
Long-term  capital  gains,  if  any,  will be  identified  separately  when  tax
information for the Trust is distributed to shareholders.  Receipt of tax exempt
income  must be  reported  on the  taxpayer's  Federal  income tax  return.  The
Statement of Additional  Information  describes how dividends and  distributions
received by Direct  Shareholders of the Trust may be reinvested in shares of any
Eligible  Fund at net asset  value.  To effect its policy of  maintaining  a net
asset value of $1.00 per share,  the Trust,  under  certain  circumstances,  may
withhold dividends or make distributions from capital or capital gains.

Tax Status of the  Trust's  Dividends.  The Trust  intends to qualify  under the
Internal Revenue Code during each fiscal year to pay "exempt-interest dividends"
to its shareholders,  and qualified during its last fiscal year. Exempt-interest
dividends  which are derived from net  investment  income earned by the Trust on
Municipal  Securities will be excludable  from gross income of the  shareholders
for Federal income tax purposes. Net investment income includes income allocated
from Municipal  Securities in the Trust's  portfolio which are free from Federal
and  California  individual  income  taxes.  This  allocation  will  be  made by
uniformly  applying a designated  percentage to all income dividends made during
the tax year. Such  designation  will normally be made following the end of each
fiscal year as to income  dividends  paid in the prior year.  The  percentage of
income designated as tax exempt may differ  substantially from the percentage of
the Trust's income that was tax exempt for a given period. The net amount of any
income on Municipal  Securities  subject to the alternative  minimum tax will be
identified when tax information is distributed by the Trust. All or a portion of
the  Trust's  exempt-interest  dividends  may be a  component  of the  "adjusted
current earnings"  preference item under the corporate  alternative minimum tax.
The Trust will report annually to shareholders the percentage of interest income
it received  during the  preceding  year on Municipal  Securities.  Shareholders
receiving  Social  Security  benefits  should  be  aware  that   exempt-interest
dividends  are a factor in  determining  whether  such  benefits  are subject to
Federal income tax.

      A shareholder  treats a dividend as a receipt of ordinary  income (whether
paid in cash or reinvested  in  additional  shares) if derived from net interest
income  earned by the Trust from one or more of: (i) certain  taxable  temporary
investments (such as certificates of deposit,  commercial paper,  obligations of
the  U.S.   government,   its  agencies  or   instrumentalities   or  repurchase
agreements),  (ii)  income  from  securities  loans,  or (iii) an  excess of net
short-term  capital gains over net long-term capital losses.  Losses realized by
shareholders  on the redemption or other  disposition of Trust shares within six
months of purchase  (which  period may be  shortened  by  regulation  and may be
extended in certain  circumstances)  will be disallowed  for Federal  income tax
purposes to the extent of exempt-interest dividends received on such shares.

     In any year in which the Trust qualifies as a regulated  investment company
under the Internal  Revenue Code, (i) the Trust will also qualify as a regulated
investment  company for California  corporate income and franchise tax purposes,
and (ii) provided that the Trust's assets satisfy the 50% requirement  discussed
below, the Trust will be qualified under California law to pay "exempt- interest
dividends"  which  will be  exempt  from the  California  personal  income  tax.
Individual  shareholders of the Trust will not be subject to California personal
income tax on  exempt-interest  dividends  received from the Trust to the extent
such distributions are attributable to interest on obligations which, if held by
an individual,  would not be subject to California personal income tax, provided
that at least 50% of the  Trust's  assets at the  close of each  quarter  of its
taxable  year are  invested in such  obligations.  Distributions  from the Trust
attributable  to other  sources  will  generally be taxable to  shareholders  as
ordinary   income.   However,   amounts   treated  as  long-term   capital  gain
distributions  for Federal income tax purposes are treated as long-term  capital
gains for California personal income tax purposes. In addition, distributions to
shareholders  of other than  exempt-interest  dividends are includable in income
subject to the  California  alternative  minimum tax.  Interest on  indebtedness
incurred or continued by  shareholders  to purchase or carry shares of the Trust
will not be deductible for Federal or California personal income tax purposes.

      Distributions  from investment income and long-term and short-term capital
gains will  generally not be excluded  from taxable  income in  determining  the
California  corporate  franchise  or  income  tax  for  corporate  shareholders.
Distributions  are also  includable  in income that is subject to the  corporate
alternative minimum tax.

      If the Trust has net realized  long-term  capital gains in a taxable year,
it may make an annual "long-term capital gains  distribution,"  which will be so
identified when paid and when tax  information is  distributed.  Long-term gains
are taxable to shareholders as long-term capital gains, whether received in cash
or  reinvested,  regardless of how long the Trust shares have been held.  Losses
realized by  shareholders  on the  redemption or other sale of shares within six
months of purchase  (which  period may be  shortened  by  regulation  and may be
extended  in certain  circumstances)  will be  treated  for  Federal  income tax
purposes as a long-term capital loss to the extent that the shareholder received
(or was treated as receiving, as described below) a capital-gain dividend on the
shares.  The Trust will report  annually to its  shareholders  the percentage of
interest income it received  during the preceding year on Municipal  Securities.
It will  also  report  the net  amount  of its  income  that is  subject  to the
alternative  minimum  tax.  Receipt of tax exempt  income  must be reported on a
taxpayer's Federal income tax return.

      Furthermore,  under Section 147(a) of the Internal  Revenue Code,  persons
who are "substantial  users" (or persons related thereto) of facilities financed
by industrial  development bonds or Private Activity Municipal Securities should
refer to "Private Activity Municipal  Securities" in the Statement of Additional
Information and should consult their own tax advisors before purchasing  shares.
No  investigation  as to the users of the  facilities  financed by such bonds is
made by the Trust.

Tax Status of the  Trust.  If the Trust  qualifies  as a  "regulated  investment
company"  under the  Internal  Revenue  Code,  it will not be liable for Federal
income taxes on amounts paid by it as dividends and distributions.  The Trust so
qualified  during its last fiscal year and intends to qualify in the current and
future fiscal years, while reserving the right not to so qualify.  However,  the
Internal   Revenue  Code  contains  a  number  of  complex  tests   relating  to
qualification  which the Trust  might not meet in any  particular  year.  If the
Trust does not  qualify,  it would be treated  for  Federal  tax  purposes as an
ordinary  corporation,  would  receive no tax  deduction  for  payments  made to
shareholders and would be unable to pay "exempt-interest dividends" as discussed
above.

ABOUT THE TRUST

Investment Objective and Policies

Investment Policies and Strategies. The investment objective and policies of the
Trust  are  described  in  the  Prospectus.  Set  forth  below  is  supplemental
information  about  those  policies.  Certain  capitalized  terms  used  in this
Statement of Additional Information are defined in the Prospectus.

      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,  should 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. To a limited degree, the Trust may engage
in  short-term  trading  to  attempt  to take  advantage  of  short-term  market
variations,  or may dispose of a portfolio security prior to its maturity if, on
the basis of a revised credit evaluation of the issuer or other  considerations,
the Trust  believes such  disposition  advisable or it needs to generate cash to
satisfy  redemptions.  In such cases,  the Trust may  realize a capital  gain or
loss. The Trust will not engage in option activity.

   
      There are, of course,  variations in the quality of Municipal  Securities,
both within a particular  classification and between classifications,  depending
on numerous factors.  The yields of Municipal  Securities depend on, among other
things,  general money market  conditions,  general  conditions of the Municipal
Securities market, size of a particular offering, the maturity of the obligation
and rating of the issue. The market value of Municipal Securities will vary as a
result of changing  evaluations of the ability of their issuers to meet interest
and principal payments,  as well as changes in the interest rates payable on new
issues of Municipal Securities.
    

Municipal Bonds. The principal  classifications  of Municipal Bonds are "general
obligations"  (secured  by the  issuer's  pledge of its full  faith,  credit and
taxing power for the payment of principal and interest),  "revenue  obligations"
(payable only from the revenues  derived from a particular  facility or class of
facilities,  or specific  excise tax or other  revenue  source) and  "industrial
development bonds."

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

      o Revenue  Bonds.  The principal  security for a revenue bond is generally
the net revenues derived from a particular facility, group of facilities, or, in
some cases,  the proceeds of a special excise or other specific  revenue source.
Revenue  bonds  are  issued  to  finance  a wide  variety  of  capital  projects
including:  electric,  gas,  water and sewer  systems;  highways,  bridges,  and
tunnels; port and airport facilities;  colleges and universities; and hospitals.
Although  the  principal  security  behind  these bonds may vary,  many  provide
additional  security in the form of a debt service  reserve fund whose money may
be used to make  principal  and interest  payments on the issuer's  obligations.
Housing finance  authorities have a wide range of security,  including partially
or fully insured  mortgages,  rent subsidized and/or  collateralized  mortgages,
and/or the net revenues from housing or other public projects.  Some authorities
provide further security in the form of a state's ability  (without  obligation)
to make up deficiencies in the debt service reserve fund.

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

Municipal Notes. Municipal Securities having a maturity when issued of less than
one year are generally known as Municipal  Notes.  Municipal Notes generally are
used to provide for short-term working capital needs and include:

      o Tax Anticipation  Notes.  Tax  anticipation  notes are issued to finance
working  capital  needs  of  municipalities.   Generally,  they  are  issued  in
anticipation  of seasonal tax revenue,  such as income,  sales,  use or business
taxes, and are payable from these specific future taxes.

     o Revenue  Anticipation  Notes.  Revenue  anticipation  notes are issued in
expectation  of  receipt of other  types of  revenue,  such as Federal  revenues
available under Federal revenue sharing programs.

     o Bond Anticipation  Notes.  Bond anticipation  notes are issued to provide
interim financing until long-term financing can be arranged.  In most cases, the
long-term bonds then
provide the money for the repayment of the notes.

     o  Construction  Loan  Notes.  Construction  loan notes are sold to provide
construction  financing.  After  successful  completion  and  acceptance,   many
projects receive permanent financing through the Federal Housing Administration.

      o Tax-Exempt Commercial Paper. Tax-exempt commercial paper is a short-term
obligation  issued by state and local  governments  or their agencies to finance
seasonal  working  capital needs or as short-term  financing in  anticipation of
longer-term financing.

Municipal Lease Obligations. From time to time the Trust may invest more than 5%
of its  net  assets  in  municipal  lease  obligations,  generally  through  the
acquisition of certificates of participation, that the Manager has determined to
be liquid  under  guidelines  set by the Board of  Directors.  Those  guidelines
require  the  Manager  to  evaluate:  (1) the  frequency  of  trades  and  price
quotations  for such  securities;  (2) the number of dealers or other  potential
buyers  willing to purchase or sell such  securities;  (3) the  availability  of
market-makers; and (4) the nature of the trades for such securities. The Manager
will also  evaluate the  likelihood of a continuing  market for such  securities
throughout  the time they are held by the Trust and the  credit  quality  of the
instrument.  Municipal  leases  may take  the form of a lease or an  installment
purchase  contract  issued by a state or local  government  authority  to obtain
funds to acquire a wide  variety of equipment  and  facilities.  Although  lease
obligations do not constitute general  obligations of the municipality for which
the  municipality's  taxing power is pledged,  a lease  obligation is ordinarily
backed by the  municipality's  covenant to budget for,  appropriate and make the
payments due under the lease  obligation.  However,  certain  lease  obligations
contain  "non-appropriation"  clauses which provide that the municipality has no
obligation to make lease or installment purchase payments in future years unless
money is appropriated for such purpose on a yearly basis. Projects financed with
certificates of participation  generally are not subject to state constitutional
debt  limitations  or other  statutory  requirements  that may be  applicable to
Municipal Securities. Payments by the public entity on the obligation underlying
the certificates are derived from available revenue sources; such revenue may be
diverted  to the  funding  of other  municipal  service  projects.  Payments  of
interest and/or  principal with respect to the  certificates  are not guaranteed
and do not constitute an obligation of the municipality.

      In addition to the risk of "non-appropriation," municipal lease securities
do not yet have a highly  developed market to provide the degree of liquidity of
conventional  municipal  bonds.  Municipal  leases,  like other  municipal  debt
obligations,  are subject to the risk of non-payment.  The ability of issuers of
municipal  leases to make timely lease  payments  may be  adversely  affected in
general  economic  downturns  and as  relative  governmental  cost  burdens  are
reallocated among federal,  state and local governmental units. Such non-payment
would  result  in a  reduction  of income to the  Trust,  and could  result in a
reduction in the value of the municipal  lease  experiencing  non-payment  and a
potential  decrease  in the  net  asset  value  of the  Trust.  Municipal  lease
obligations purchased by the Trust must meet the requirements of Rule 2a-7.

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

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

      Interest on certain  private  activity  bonds issued after August 7, 1986,
which  continues  to be  tax-exempt  will be  treated as a tax  preference  item
subject  to the  Federal  alternative  minimum  tax  (discussed  below) to which
certain  taxpayers  are subject.  Further,  a private  activity bond which would
otherwise  be a  qualified  tax-exempt  private  activity  bond will not,  under
Internal Revenue Code Section 147(a),  be a qualified bond for any period during
which it is held by a person who is a "substantial user" of the facilities or by
a "related person" of such a substantial user. This "substantial user" provision
is  applicable   primarily  to  exempt  facility  bonds,   including  industrial
development  bonds. The Trust may not be an appropriate  investment for entities
which are  "substantial  users" (or  persons  related  thereto)  of such  exempt
facilities,  and such  persons  should  consult  their own tax  advisors  before
purchasing  shares. A "substantial user" of such facilities is defined generally
as a "non-exempt person who regularly uses part of a facility" financed from the
proceeds  of exempt  facility  bonds.  Generally,  an  individual  will not be a
"related  person"  under the Internal  Revenue Code unless such  investor or the
investor's   immediate   family   (spouse,   brothers,   sisters  and  immediate
descendants)  own directly or indirectly in the aggregate more than 50% in value
of the equity of a corporation or partnership which is a "substantial user" of a
facility  financed  from the  proceeds of exempt  facility  bonds.  In addition,
limitations on the dollar amount of private  activity bonds which each state may
issue were revised  downward by the Tax Reform Act, which will reduce the supply
of such bonds. The value of the Trust's  portfolio could be affected if there is
a reduction in the  availability of such bonds.  That value may also be affected
by a 1988 U.S.  Supreme Court decision  upholding the  constitutionality  of the
imposition  of a Federal  tax on the  interest  earned on  Municipal  Securities
issued in bearer form.

     A Municipal  Security is treated as a taxable private activity bond under a
test for (a) a trade or business  use and  security  interest,  or (b) a private
loan restriction. Under the trade or business use and security interest test, an
obligation is a private  activity bond if (i) more than 10% of bond proceeds are
used for  private  business  purposes  and (ii)  10% or more of the  payment  of
principal or interest on the issue is directly or  indirectly  derived from such
private use or is secured by the privately used property or the payments related
to the use of the  property.  For  certain  types of  uses,  a 5%  threshold  is
substituted for this 10% threshold.  (The term "private  business use" means any
direct or indirect  use in a trade or business  carried on by an  individual  or
entity  other than a state or  municipal  governmental  unit.) Under the private
loan restriction,  the amount of bond proceeds which may be used to make private
loans is  limited to the lesser of 5% or $5.0  million  of the  proceeds.  Thus,
certain  issues of  Municipal  Securities  could  lose their  tax-exempt  status
retroactively  if the  issuer  fails  to  meet  certain  requirements  as to the
expenditure of the proceeds of that issue or use of the bond-financed  facility.
The Trust makes no independent investigation of the users of such bonds or their
use of  proceeds.  If the Trust  holds a bond that loses its  tax-exempt  status
retroactively,  an  adjustment  to the  tax-exempt  income  previously  paid  to
shareholders may result.

      The  Federal  alternative  minimum  tax is  designed  to  ensure  that all
taxpayers pay some tax, even if they have no other income tax  obligation.  This
is  accomplished  in part by including in taxable  income certain tax preference
items in arriving at alternative minimum taxable income. The Tax Reform Act made
tax-exempt  interest from certain  private  activity bonds a tax preference item
for purposes of the alternative minimum tax on individuals and corporations. Any
exempt-interest  dividend paid by a regulated investment company will be treated
as  interest  on  a  specific  private  activity  bond  to  the  extent  of  its
proportionate  share of the  interest on such bonds  received  by the  regulated
investment  company.  The U.S.  Treasury  is  authorized  to  issue  regulations
implementing  this provision.  In addition,  corporate  taxpayers subject to the
alternative  minimum  tax  may,  under  some  circumstances,   have  to  include
exempt-interest  dividends in  calculating  their  alternative  minimum  taxable
income in situations  where the "adjusted  current  earnings" of the corporation
exceeds its alternative  minimum  taxable  income.  The Trust may hold Municipal
Securities  the  interest  on  which  (and  thus a  proportionate  share  of the
exempt-interest  dividends  paid by the Trust)  will be  subject to the  Federal
alternative  minimum tax. For calendar  year 1996,  approximately  10.50% of the
Trust dividends paid to shareholders were a tax preference item for shareholders
subject to the Federal alternative minimum tax. The Trust anticipates that under
normal  circumstances  it will not  purchase  any such  securities  in an amount
greater than 20% of the Trust's total assets.

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

         o Quality.  Eligible  securities  are  securities  that have received a
rating  in one of the two  highest  short-term  rating  categories  by a  rating
organizations.   Rating   organization  are  designated  by  the  SEC.  Eligible
securities may be First Tier or Second Tier  securities.  First Tier  securities
are those that have  received a rating in the  highest  category  for short term
debt  obligations  by at least  two  rating  organizations.  If only one  Rating
Organization  has rated the security,  it must be rated in the highest  category
for that Rating Organization.  U.S. government  securities and securities issued
by a registered money market mutual fund are also First Tier Securities.
      The Trust may also buy Second  Tier  Conduit  Securities.  These  Eligible
Securities are securities rated by rating  organizations  but are not First tier
Securities.  Conduit  Securities  are  Municipal  Securities  such as industrial
development  or revenue  bonds issued to finance  non-government  projects.  The
payment  of the  principal  and  interest  on a  Conduit  Security  is  not  the
obligation of the municipal issuer, but is the obligation of another person such
as the user of the facility.  The Trust may not invest more than 5% of its total
assets in Second Tier Conduit Securities.

      The Trust may also buy unrated  securities that the Manager determines are
comparable  in quality to a First or Second Tier  security  by applying  certain
criteria  established  by the Board to  determine  its  creditworthiness.  These
criteria require a high quality short term or long-term rating (depending on the
security)  from a Rating  Organization.  Unrated  securities  the  Trust may buy
include asset backed  securities  and securities  subject to Demand  Features or
Guarantees.

      The Trust may purchase a security  subject to a Guarantee if the Guarantee
is an Eligible Security or a first Tier Security.  The Trust may also purchase a
security  subject to a Conditional  Demand  Feature if the demand  feature is an
Eligible  Security  and the  Manager  has decided  that the  Conditional  Demand
Feature meets the requirements imposed by Rule 2a-7.

     o  Diversification.  With respect to 75% of its total assets, the Trust may
not invest more than 55% of its total assets in securities issued by one issuer.
It must not invest more than 5% of its total assets in  securities of one issuer
unless the  security  is a First Tier  Security.  The Trust also must not invest
more than 1% of its total  assets or $1.0  million,  whichever  is  greater,  in
Second Tier Securities of one issuer. For diversification purposes, the Trust is
considered to have purchased the security  underlying a repurchase  agreement if
the repurchase agreement is fully collateralized.  For a refunded security,  the
Trust is  considered  to have  the U.S.  government  securities  underlying  the
refunded security. For Conduit Securities,  the Trust considers the issuer to be
the person  ultimately  responsible for payment of the obligation.  If the Trust
buys an asset  backed  security,  the issuer of the security is deemed to be the
Special Purpose Entity which issued the security. A special purpose entity is an
entity  which is  organized  solely  for the  purpose of  issuing  asset  backed
securities.  If the asset backed securities issued by the special purpose entity
include the  obligations of another person or another special purpose entity and
those obligations amount to 10% or more of the asset backed securities the Trust
buys,  that other person or entity is  considered to be the issuer of a pro rata
percentage of the asset backed security.

      For  diversification  purposes,  the Trust may buy a  security  subject to
Demand  Feature or  Guarantee.  In this case,  with  respect to 75% of its total
assets, the Trust may not invest more than 10% of its total assets in securities
issued by or subject to Demand Features or Guarantees issued by the same issuer.
If the Demand Feature or Guarantee is a Second Tier security,  the Trust may not
invest more than 5% of its total assets in securities subject to Demand Features
or Guarantees from the same issuer.  And, the Trust may not invest more than 10%
of its total  assets in  securities  issued by or subject to Demand  Features or
Guarantees from the same issuer.  However, if the Demand Feature or Guarantee is
issued by a person who is a  non-controlled  person,  the Trust does not have to
limit its  investments  to no more than 10% of its  total  assets in  securities
issued by or subject to Demand Features or Guarantees from the same issuer.

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

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

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

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

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

   
Repurchase  Agreements.  In a  repurchase  transaction,  the  Trust  acquires  a
security,  from,  and  simultaneously  resells it to, an approved  vendor  which
satisfies the requirements of Rule 2a-7 and procedures adopted by the Board. The
resale  price  exceeds  the  purchase  price  by  an  amount  that  reflects  an
agreed-upon  interest rate  effective for the period during which the repurchase
agreement is in effect.  The majority of these transactions run from day to day,
and delivery pursuant to the resale typically will occur within one to five days
of the purchase. Repurchase agreements are considered loans under the Investment
Company Act,  collateralized by the underlying security.  The Trust's repurchase
agreements  require  that at all times  while  the  repurchase  agreement  is in
effect, the value of the collateral must equal or exceed the repurchase price to
fully  collateralize the repayment  obligation.  Additionally,  the Manager will
impose  creditworthiness  requirements to confirm that the vendor is financially
sound and will continuously monitor the collateral's value.
    

Loans of Portfolio Securities.  To attempt to increase its income, the Trust may
lend its portfolio  securities to qualified  borrowers (other than in repurchase
transactions)  if the  loan is  collateralized  in  accordance  with  applicable
regulatory  requirement  and if,  after  any loan,  the value of the  securities
loaned do not  exceed 25% of the value of its total  assets.  The Trust does not
intend to engage in securities loan transactions during the current fiscal year.
The income from such loans, when distributed by the Trust, will be taxable.

       Under applicable  regulatory  requirements (which are subject to change),
the loan  collateral  must, on each business day, be at least equal to the value
of the loaned  securities  and must  consist of cash,  bank letters of credit or
securities  of the U.S.  Government  (or its agencies or  instrumentalities)  or
other  cash  equivalents  in which  the  Trust is  permitted  to  invest.  To be
acceptable as collateral,  letters of credit must obligate a bank to pay amounts
demanded by the Trust if the demand  meets the terms of the  letter.  Such terms
and the issuing bank must be  satisfactory  to the Trust.  The Trust receives an
amount equal to the dividends or interest on loaned securities and also receives
one or more of: (a)  negotiated  loan fees,  (b) interest on securities  used as
collateral,  or (c) interest on short-term debt  securities  purchased with such
loan  collateral;  either type of interest may be shared with the borrower.  The
Trust may also pay reasonable  finder's,  custodian and administrative  fees and
will not lend its  portfolio  securities  to any officer,  trustee,  employee or
affiliate of the Trust or the Manager.  The terms of the Trust's loans must meet
applicable  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.  Income from securities loans
is not included in the exempt-interest dividends paid by the Trust.

Special Investment Considerations - California Municipal Securities

As stated in the  Prospectus,  the values of the  Trust's  California  Municipal
Securities  are highly  sensitive to the fiscal  stability of California and its
subdivisions,  agencies,  instrumentalities  or  authorities,  which  issue  the
Municipal  Securities in which the Trust  concentrates its investments.  Certain
amendments to the California State constitution, legislative measures, executive
orders, civil actions and voter initiatives in recent years that could adversely
affect the  ability of  California  issuers to pay  interest  and  principal  on
Municipal Securities are described below. The following constitutes only a brief
summary,  and is based on  information  drawn  from the  relevant  statutes  and
certain other publicly  available  information.  The Trust has not independently
verified such information.

   
      Changes  in  California  constitutional  and other  laws  during  the last
several years have caused  concerns  about the ability of  California  state and
municipal  issuers to obtain  sufficient  revenue to pay their bond obligations.
California  County  and other  local  government  budgets  may be  significantly
affected by State budget decisions beyond their control.
    

       In 1978,  California  voters  approved  an  amendment  to the  California
Constitution  known  as  Proposition  13,  which  added  Article  XIIIA  to  the
California Constitution.  Article XIIIA limits ad valorem taxes on real property
and  restricts the ability of taxing  entities to increase real property  taxes.
However,  legislation  passed  subsequent  to  Proposition  13 provided  for the
redistribution  of  California's  General  Fund surplus to local  agencies,  the
reallocation  of revenues to local  agencies and the assumption of certain local
obligations  by the  state  so as to help  California  municipal  issuers  raise
revenue to pay their bond obligations.  It is unknown whether additional revenue
redistribution  legislation  will be  enacted  in the  future  and  whether,  if
enacted,  such legislation will provide  sufficient  revenue for such California
issuers to pay their obligations.

      The state is also  subject to another  constitutional  amendment,  Article
XIIIB,  which may have an  adverse  impact  on  California  state and  municipal
issuers.  Article XIIIB restricts the state from spending certain appropriations
in excess of an appropriations limit imposed for each state and local government
entity.  If revenues  exceed such  appropriations  limit,  such revenues must be
returned  either  as  revisions  in the tax  rates  or fee  schedules.  In 1988,
California  voters  approved an  initiative  known as  Proposition  98, which in
addition to amending  Article  XIIIB,  amended  Article XVI to require a minimum
level of funding for public schools and community colleges.

      In 1986, California voters approved an initiative known as Proposition 62,
which,  among  other  things,  requires  that any tax for  general  governmental
purposes  imposed by a local  government be approved by  two-thirds  vote of the
governmental  entity's  legislative body and by a majority of its electorate and
that any special tax imposed by a local  government  be approved by a two-thirds
vote of the  electorate.  In September 1995 the California  Supreme Court upheld
the constitutionality of Proposition 62, creating uncertainty as to the legality
of certain local taxes enacted by non-charter cities in California without voter
approval. It is not possible to predict the impact of the decision.

     In  November  1996,   California  voters  approved   Proposition  218.  The
initiative  applied the provisions of Proposition 62 to all entities,  including
charter cities.  It requires that all taxes for general purposes obtain a simple
majority  popular vote and that taxes for special  purposes  obtain a two-thirds
majority vote.  Prior to the  effectiveness  of Proposition  218, charter cities
could levy certain taxes such as transient  occupancy  taxes and utility  user's
taxes without a popular vote.  Proposition  218 will also limit the authority of
local  governments  to impose  property-related  assessments,  fees and charges,
requiring that such assessments be limited to the special benefit  conferred and
prohibiting their use for general  governmental  services.  Proposition 218 also
allows   voters   to  use   their   initiative   power  to   reduce   or  repeal
previously-authorized taxes, assessments, fees and charges.

   
      Proposition 9 on the November,  1998,  State ballot would overturn certain
aspects of  legislation  enacted  in 1996 and 1997 to  deregulate  the  electric
industry in California.  As part of this deregulation,  the three investor owned
utilities  in  California  issued  about $6  billion in  aggregate  of the "rate
reduction bonds" to finance the stranded costs of certain uneconomic facilities.
These  bonds are repaid  through a  surcharge  placed on  residential  and small
business customers' bills. the legislation  authorizing  issuance of these bonds
included a pledge that the State would not  interfere  with the levying of these
surcharges  without  providing  other  means to  repay  the  bonds.  One part of
Proposition 9 would be the  cancellation of the utilities'  authority to collect
these  surcharges.  If proposition 9 would be the cancellation of the utilities'
authority  to collect  these  surcharges.  If  proposition  9 is approved by the
voters.  it is  anticipated  that  litigation  will  be  filed  to  declare  the
initiative whether any State General Fund moneys eventually might be required to
repay the rate reduction  bonds. It is also not possible to predict what effect,
if any,  passage of Proposition 9 will have on the  marketability of outstanding
California State and local obligations or on the availability of capital for, or
cost of, future State and local borrowing.
    

      Because of the uncertain  impact of the  aforementioned  legislation,  the
possible  inconsistencies  in the  respective  terms  of the  statutes  and  the
impossibility of predicting the level of future appropriations and applicability
of related  statutes to such questions,  it is not currently  possible to assess
the impact of such  legislation  and  policies  on the long term  ability of the
State of California  and California  municipal  issuers to pay interest or repay
principal on their obligations.

      In addition,  certain tax-exempt  securities in which the Trust may invest
may be obligations payable solely from the revenues of specific institutions, or
may be secured by  specific  properties,  which are  subject  to  provisions  of
California law that could adversely affect the holders of such obligations.  For
example,  the revenues of California  health care institutions may be subject to
state laws, and  California  law limits the remedies of a creditor  secured by a
mortgage or deed of trust on real property.

   
     California's economic recovery from the recent recession is continuing at a
strong pace. The rate of economic  growth in California in 1997, in terms of job
gains,  exceeded that of the rest of the United  States.  The State added nearly
430,000   non-farm   jobs  during  1997.  In  1996   California   surpassed  its
pre-recession employment peak of 12.7 million jobs. The unemployment rate, while
still  higher  than the  national  average,  fell to 5.8  percent  in June 1998,
compared  to over 10  percent  during the  recession.  Many of the new jobs were
created  in such  industries  as  computer  services,  software  design,  motion
pictures and high technology manufacturing.  Business services, export trade and
other  manufacturing also experienced  growth. All major economic regions of the
State grew. The rate of employment  growth for the Los Angeles region  indicates
that its growth has almost  caught up with that in the San  Francisco bay region
on a population  share basis.  The unsettled  financial  situation  occurring in
certain  Asian  economies  may  adversely  affect  the  State's   export-related
industries and, therefore, the State's rate of economic growth.

      On August 21,  1998,  the  Governor  signed the 1998-99  Budget act which,
along with various implementing measures, authorizes total State spending of $72
billion.  This  total  includes  $57.3  billion  from the  General  Fund (a 7.3%
increase from  1997-98) and $14.7 billion from special funds (a 1.7%  increase).
Before signing the Budget Act, the Governor used his line-item veto authority to
delete  $1.5  billion in  1998-99  appropriations  adopted  by the  Legislature,
including  $1.4 billion in General Fund  spending.  The Governor  indicated that
$250 million of the cuts he made to K-12  education were being set aside pending
legislation involving various school reforms.

      Continued State economic expansion and large revenue increases enabled the
Governor and the Legislature to provide both  significant tax relief and program
spending increases in the 1998-99 budget. These include an initial 25% reduction
in the vehicle  license fee, large increases in education  funding,  and cost of
living adjustments and grant restorations for social services programs.  Because
of the State of California's  continuing  budget  problems,  the state's General
Obligation bonds were downgraded in July 1994 from Aa to A1 by Moody's,  from A+
to A by Standard & Poor's and from AA to A by Fitch.  All three rating  agencies
expressed  uncertainty  in the  state's  ability to balance  its budget by 1996.
However,  in 1996, citing  California's  improving economy and budget situation,
both Fitch and S&P raised  their  ratings  from A to A+ and in 1997 Fitch raised
its rating to AA-.

      In October  1998,  Moody's  raised  its  rating  from A1 to Aa3 citing the
State's  continuing  economic  recovery and a number of actions taken to improve
the  State's  credit  condition,  including  the  rebuilding  of cash and budget
reserves.

      On  December  6, 1994,  Orange  County  (California)  became  the  largest
municipality  in the  United  States to file for  protection  under the  Federal
bankruptcy  laws. The filing stemmed from  approximately  $1.7 billion in losses
suffered  by the  county's  investment  pool  due to  investment  in  high  risk
"derivative"  securities.  In  September  1995 the  state  legislature  approved
legislation permitting Orange County to use for bankruptcy recovery $820 million
over 20 years in sales  taxes  previously  earmarked  for  highway,  transit and
development.  In June 1996 the County  completed an $880  million bond  offering
secured by real  property  owned by the  County.  On June 12,  1996,  the County
emerged  from  bankruptcy.  On January 7, 1997,  Orange  County  returned to the
municipal  bond market with a $136 million bond issue maturing in 13 years at an
insured  yield of 7.23 percent.  In December 1997 Moody's  raised its ratings on
$325  million  of Orange  County  pension  obligation  bonds to Baa3 from Ba. In
February 1998 Fitch assigned  outstanding Orange County pension obligation bonds
a BBB rating.

     Los Angeles  County,  the nation's  largest  county,  has also  experienced
financial difficulty. In August 1995 the credit rating of the county's long-term
bonds was  downgraded  for the third time since 1992 as a result of, among other
things,  severe  operating  deficits  for the county's  health care  system.  In
addition,  the County was affected by an ongoing loss of revenue caused by state
property  tax  shift  initiatives  in 1993  through  1995.  In June 1998 the Los
Angeles  County Board of  Supervisors  approved an  approximately  $13.6 billion
1990-99 budget, which was more than 5% larger than the 1997-98 budget, and which
did not require cuts in services and jobs to balance.  The Board of  Supervisors
reserved  the  right to make  further  changes  to  reflect  revenue  allocation
decisions in the final State budget.

      In October 1997 the Governor issued  Executive Order W-163-97 stating that
Year 2000  solutions  would be a State priority and requiring each agency of the
State,  no later than  December 31, 1998, to address year 2000 problems in their
essential  systems and protect  those systems from  corruption by  non-compliant
systems,   in  accordance  with  the  Department  of  Information   Technology's
California  2000  Program.  There can be no assurance  that steps being taken by
state or local government agencies with respect to the Year 2000 problem will be
sufficient  to avoid any adverse  impact upon the budgets or operations of those
agencies or upon the Fund.
    

Other Investment Restrictions

The  Trust's  most  significant  investment  restrictions  are set  forth in the
Prospectus.   The  following   investment   restrictions  are  also  fundamental
investment policies of the Trust and, together with the fundamental policies and
investment objective described in the Prospectus,  cannot be changed without the
vote of a majority  of the  Trust's  outstanding  shares.  Under the  Investment
Company Act,  such a majority  vote is defined as the vote of the holders of the
lesser of (i) 67% or more of the  shares  present or  represented  by proxy at a
shareholder's meeting, if the holders of more than 50% of the outstanding shares
are present or  represented by proxy,  or (ii) more than 50% of the  outstanding
shares. Under these additional restrictions, the Trust cannot:

      o invest in commodities or commodity contracts,  or invest in interests in
oil, gas, or other mineral exploration or development programs;

      o invest in real estate;  however,  the Trust may purchase Municipal Bonds
or Notes secured by interests in real estate;

     o make short sales of securities or purchase  securities on margin,  except
for  short-term  credits  necessary  for the clearance of purchases and sales of
portfolio securities;

      o  invest  in or hold  securities  of any  issuer  if those  officers  and
Trustees of the Trust or the Manager  individually  owning more than 0.5% of the
securities  of such issuer  together own more than 5% of the  securities of such
issuer;

      o  underwrite securities of other companies; or

      o invest in securities of other investment companies except as they may be
acquired as part of a merger, consolidation or acquisition of assets.

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

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

      Unless the Prospectus or this Statement of Additional  Information  states
that a percentage  restriction  applies on an ongoing basis,  it applies only at
the time the Trust makes an investment and the Trust need not sell securities to
meet  the  percentage  limits  if the  value  of  the  investment  increased  in
proportion to the size of the Trust.  For purposes of the Trust's  policy not to
concentrate its assets,  described under the fourth restriction number listed in
the Prospectus,  the Trust has adopted the industry classifications set forth in
Appendix  B  to  this  Statement  of  Additional  Information.  This  is  not  a
fundamental policy.

Organization and History of the Trust

The Trust's  Declaration of Trust contains an express  disclaimer of shareholder
or  Trustee   liability   for  the  Trust's   obligations,   and   provides  for
indemnification  and  reimbursement  of  expenses  out of its  property  for any
shareholder held personally liable for its obligations. The Declaration of Trust
also provides that the Trust shall, upon request,  assume a defense of any claim
made against any  shareholder for any act or obligation of the Trust and satisfy
any judgment thereon.  Thus, while  Massachusetts law permits a shareholder of a
trust (such as the Trust) to be held  personally  liable as a "partner"  for the
Trust's obligations under certain circumstances, the risk of a Trust shareholder
incurring any financial loss on account of such shareholder liability is limited
to the relatively remote  circumstance in which the Trust itself would be unable
to meet its  obligations.  Any person  doing  business  with the Trust,  and any
shareholder of the Trust,  agrees under the Trust's Declaration of Trust to look
solely to the assets of the Trust for  satisfaction of any claim or demand which
may arise out of any dealings  with the Trust,  and the  Trustees  shall have no
personal liability to any such person, to the extent permitted by law. It is not
contemplated  that regular  annual  meetings of  shareholders  will be held. The
Trust will hold meetings when required to do so by the Investment Company Act or
other  applicable law, or when a shareholder  meeting is called by the Trustees.
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 its outstanding shares.
In  addition,  if the Trustees  receive a request from at least 10  shareholders
(who have been  shareholders  for at least six months)  holding in the aggregate
shares  of the Trust  valued at  $25,000  or more or  holding  1% or more of the
Trust's  outstanding  shares,  whichever is less,  that they wish to communicate
with other  shareholders to request a meeting to remove a Trustee,  the Trustees
will then either make the Trust's  shareholder  list available to the applicants
or  mail  their  communication  to all  other  shareholders  at the  applicants'
expense,  or the  Trustees may take such other action as set forth in Section 16
of the Investment Company Act.

with each of the Denver  Oppenheimer funds. As of October 16, 1998, the Trustees

an employees benefit plan for employees of OppenheimerFunds, Inc., the parent of
the Manager (for which two of the officers listed below,  Ms.  Macaskill and Mr.

(1) For the 1997 calendar year. (2) Committee positions effective July 1, 1997.
    
(3) Prior to July 1, 1997, Messrs.  Conrad and Kirchner were also members of the
Audit and Review Committee.

   
Deferred  Compensation  Plan.  The Board of  Trustees  has  adopted  a  Deferred
Compensation Plan for  disinterested  Trustees that enables Trustees 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 the Plan will be vary based upon the  performance  of the
selected  funds.  Deferral of Trustees'  fees under the Plan will not materially
affect the Trust's assets,  liabilities and net income per share.  The Plan will
not  obligate  the Trust to retain  the  services  of any  Trustee or to pay any
particular amount of compensation to the Trustee. Pursuant to an Order issued by
the  Securities  and  Exchange   Commission,   the  Trust  may  invest  [without
shareholder  approval and not  withstanding its fundamental  policy  restricting
investments in other open-end investment companies,  as described in the Trust's
Statement of Additional  Information] in the funds selected by the Trustee under
the Plan,  for the  limited  purpose of  determining  the value of the  Trustees
deferred fee account.

Major Shareholders. As of October 16,1998 A.G. Edwards & Sons, Inc. ("Edwards"),
1 North  Jefferson  Avenue,  St.  Louis,  MO  63103,  was the  record  owner  of
172,877,342.360 shares of the Trust (99.6% of outstanding shares). The Trust has
been informed that the shares held of record by Edwards were beneficially  owned
by its  brokerage  clients.  As of that date, no other person owned of record or
was known by the Trust to own beneficially 5% or more of the Trust's outstanding
shares.
    

The Manager and Its Affiliates

   
The  Manager is  wholly-owned  by OFI,  which is a  wholly-owned  subsidiary  of
Oppenheimer   Acquisition  Corp.   ("OAC"),  a  holding  company  controlled  by
Massachusetts  Mutual Life Insurance  Company.  OAC is owned by certain of OFI's
directors  and  officers,  some of whom may serve as officers of the Trust,  and
three of whom (Messrs.  Swain and Bowen and Ms.  Macaskill) serve as Trustees of
the Trust.
    

Investment  Advisory  Agreement.  A  management  fee is  payable  monthly to the
Manager under the terms of the investment advisory agreement between the Manager
and the Trust (the "Agreement"),  and is computed on the aggregate net assets of
the Trust as of the close of  business  each day.  The  Agreement  requires  the
Manager,  at its  expense,  to provide  the Trust with  adequate  office  space,
facilities  and  equipment,  and to provide and supervise the  activities of all
administrative   and   clerical   personnel   required   to  provide   effective
administration  for the Trust,  including the  compilation  and  maintenance  of
records with respect to its operations,  the preparation and filing of specified
reports, and the 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  Agreement  or by the  Distributor  of the shares of the
Trust,  are paid by the Trust.  A description of examples of such expenses is in
the Prospectus. The Agreement contains no expense limitation.

   
      The Manager has undertaken  that the total  expenses of the Trust,  in any
fiscal year of the Trust,  exclusive of taxes,  interest,  brokerage commissions
(if any) and  non-recurring  expenses,  including  litigation,  shall not exceed
0.80% of the  average  annual  net  assets  of the  Trust.  The  payment  of the
management fee at the end of any month will be reduced so that there will not be
any accrued but unpaid liability under those expense limitations. Any assumption
of the  Trust's  expenses  under this  arrangement  lowers the  Trust's  overall
expense  ratio and  increases  its yield and total  return  during the time such
expenses  are  assumed.  The  Manager  reserves  the right to vary the amount of
expenses  assumed or eliminate the  assumption of expenses  altogether.  For the
fiscal  years  ended  June 30,  1996,  June 30,  1997  and  June 30,  1998,  the
management  fees  payable by the Trust would have been  $565,052,  $644,397  and
$801,264, respectively without the Manager's voluntary expense assumption. Those
amounts do not reflect the effect of the expense assumptions of $16,016,  $7,679
and $2,862 respectively, in those periods by the Manager.
    

      The  Agreement  provides that in the absence of willful  misfeasance,  bad
faith,  or  gross  negligence  in the  performance  of its  duties  or  reckless
disregard of its  obligations and duties  thereunder,  the Manager is not liable
for any loss  sustained  by reason of any good  faith  errors  or  omissions  in
connection with any matters covered by the Agreement.  The Agreement permits the
Manager to act as investment  advisor for any other person,  firm or corporation
and to use the name  "Centennial"  in  connection  with  one or more  additional
companies for which it may act as investment advisor or general distributor.  If
the Manager shall no longer act as investment advisor to the Trust, the right of
the Trust to use the name "Centennial" as part of its name may be withdrawn.

The  Custodian.  The  Custodian's   responsibilities  include  safeguarding  and
controlling  the Trust's  portfolio  securities  and  handling  the  delivery of
portfolio  securities to and from the Trust.  The Manager has represented to the
Trust  that its  banking  relationship  with the  Custodian  have  been and will
continue to be  unrelated to and  unaffected  by the  relationships  between the
Trust and the  Custodian.  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 or its affiliates.

The  Transfer  Agent.  The  Transfer  Agent  (Shareholder  Services,   Inc.)  is
responsible  for maintaining  the Trust's  shareholder  registry and shareholder
accounting records, and for shareholder servicing and administrative functions.

The Distributor. Under the General Distributor's Agreement between the Trust and
the Distributor,  the Distributor acts as the Trust's  principal  underwriter in
the continuous  public  offering of its shares.  The General  Distributor is not
obligated to sell a specific number of shares. Expenses normally attributable to
sales (other than those paid under the Service Plan),  including advertising and
the cost of printing  and mailing  prospectuses  other than those  furnished  to
existing shareholders, are borne by the Distributor.

Independent Auditors and Financial  Statements.  The independent auditors of the
Trust audit the Trust's  financial  statements  and perform  other related audit
services.  They also act as  auditors  for the Manager  and OFI,  the  Manager's
immediate  parent, as well as for certain other funds advised by the Manager and
OFI.

Portfolio  Transactions.  Portfolio decisions are based upon the recommendations
and  judgment of the Manager  subject to the overall  authority  of the Board of
Trustees. As most purchases made by the Trust are principal  transactions at net
prices,  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 it is determined  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 and  reliable  execution of orders at the
most  favorable  net price.  If  brokers  are used for  portfolio  transactions,
transactions  may be  directed  to brokers  furnishing  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,
and 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.  Such
research,  which may be supplied  by a third party at the  instance of a broker,
includes 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 for in commission  dollars.
The research  services  provided by brokers broaden the scope and supplement the
research  activities  of the Manager by making  available  additional  views for
consideration  and  comparisons,  and  enabling  the  Manager  to obtain  market
information  for the  valuation of securities  held in the Trust's  portfolio or
being  considered  for  purchase.  The Trust  does not direct  the  handling  of
purchases  or sales of  portfolio  securities,  whether on a principal or agency
basis, to brokers for selling shares of the Trust. No portfolio transactions are
handled by brokers  which are  affiliated  with the Trust or the Manager if that
broker is acting as  principal.  The Trust's  policy of investing in  short-term
debt  securities with maturities of less than one year results in high portfolio
turnover. However, since brokerage commissions, if any, are small and securities
are usually held to maturity, high turnover does not have an appreciable adverse
effect upon the net asset value or income of the Trust.

      Other funds advised by the Manager have investment objectives and policies
similar to that of the Trust.  Such other  funds may  purchase  or sell the same
securities at the same time as the Trust, which could affect the supply or price
of such  securities.  If two or more of such funds purchase the same security on
the same day from the same  dealer,  the  Manager  may  average the price of the
transactions and allocate the cost among such funds.

Service Plan

   
The Trust has  adopted a service  plan  (the  "Plan")  under  Rule  12b-1 of the
Investment Company Act, as described in the Prospectus.  No payment will be made
by the  Distributor  to any  Recipient if the  aggregate  net asset value of the
Trust  shares held by it or its  customers  at the end of a calendar  quarter is
less than the minimum level of qualified holdings, if any, established under the
Plan from time to time by the  "Independent  Trustees".  Currently,  no  minimum
level of qualified  holdings has been established by the Board of Trustees.  The
Board of Trustees has set the fee or the maximum although the Trustees may lower
the fee.  For the Trust's  fiscal year ended June 30, 1998,  payments  under the
Plan totaled $320,662 all of which was paid by the Distributor to Recipients.
    

      The  Distributor  has entered into  Supplemental  Distribution  Assistance
Agreements  ("Supplemental  Agreements")  under the Plan with  selected  dealers
distributing  shares of Centennial  America Fund,  L.P.,  Centennial  Government
Trust,  Centennial New York Tax Exempt Trust,  Oppenheimer Cash Reserves and the
Trust.  Quarterly payments by the Distributor for distribution- related services
will range from 0.10% to 0.30%,  annually,  of the  average  net asset  value of
shares of the above-mentioned  funds owned during the quarter beneficially or of
record by the dealer or its customers.  However, no payment shall be made to any
dealer for any quarter during which the average net asset value of shares of the
above-mentioned  funds owned during that quarter by the dealer or its  customers
is less than $5 million.  Payments made pursuant to Supplemental  Agreements are
not a Trust expense, but are made by the Distributor out of its own resources or
out of the resources of the Manager which may include  profits  derived from the
advisory  fee  it  receives  from  the  Trust.  Payments  to  affiliates  of the
Distributor are not permitted under the Supplemental Agreements.

     The Plan shall,  unless  terminated as described below,  continue in effect
from year to year but only so long as such continuance is specifically  approved
at least  annually by the Trust's Board of Trustees  including  its  Independent
Trustees  by a vote cast in person at a meeting  called  for that  purpose.  The
Supplemental  Agreements are subject to the same renewal  requirement.  The Plan
and the  Supplemental  Agreements may be terminated at any time by the vote of a
majority  of the  Independent  Trustees  or by the  vote  of  the  holders  of a
"majority  of the  Trust's  outstanding  voting  securities"  (as defined in the
Investment   Company  Act).  The  Supplemental   Agreements  will  automatically
terminate  in the event of their  "assignment"  (as  defined  in the  Investment
Company Act),  and each may be terminated by the  Distributor:  (i) in the event
the  Trust  amends  the Plan,  or (ii) if the net  asset  value of shares of the
above-mentioned  funds covered by Supplemental  Agreements held by the dealer or
its customers is less than $5 million for two or more  consecutive  quarters.  A
dealer may terminate a  Supplemental  Agreement at any time upon giving 30 days'
notice. The Plan may not be amended without shareholder  approval,  as set forth
above,  to  increase  materially  the  amount of  payments  to be made,  and all
material amendments must be approved by the Board and the Independent Trustees.

      Under the Plan, no payment will be made to any Recipient in any quarter if
the  aggregate  net asset value of all Trust  shares held by the  Recipient  for
itself and its  customers did not exceed a minimum  amount,  if any, that may be
determined from time to time by a majority of the Trust's Independent  Trustees.
The Board of  Trustees  has set the fee at the  maximum  rate and set no minimum
amount.  The Plan  permits the  Distributor  and the Manager to make  additional
distribution  payments to Recipients from their own resources (including profits
from advisory  fees) at no cost to the Trust.  The  Distributor  and the Manager
may, in their sole  discretion,  increase or decrease the amount of distribution
assistance payments they make to Recipients from their own assets.

      While the Plan is in effect,  the  Treasurer of the Trust shall  provide a
report to the Board of Trustees in writing at least  quarterly  on the amount of
all payments made pursuant to the Plan and the identity of each  Recipient  that
received any such payment and the purposes for which the payments were made. The
Plan further  provides that while it is in effect,  the selection and nomination
of those Trustees of the Trust who are not "interested  persons" of the Trust is
committed to the discretion of the Independent  Trustees.  This does not prevent
the involvement of others in such selection and nomination if the final decision
as to the selection or  nomination is approved by a majority of the  Independent
Trustees.

Performance of the Trust

   
Yield  Information.  The Trust's  current  yield is  calculated  for a seven-day
period of time in  accordance  with  regulations  adopted  under the  Investment
Company Act. 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 (a) adding 1 to the base
period  return  (obtained  as described  above),  (b) raising the sum to a power
equal  to 365  divided  by 7 and (c)  subtracting  1 from  the  result.  For the
seven-day  period ended June 30, 1998,  the Trust's  current yield was 2.76% and
its compounded effective yield was 2.79%.
    

      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.  Since 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,  the return on dividends declared during a period may not be the same
on an annualized basis as the yield for that period.

   
      The Trust's "tax  equivalent  yield" adjusts the Trust's current yield, as
calculated  above, by a stated combined Federal and California tax rate. The tax
equivalent  yield is computed by dividing the tax-exempt  portion of the Trust's
current yield by one minus a stated income tax rate and adding the result to the
portion (if any) of the Trust's  current yield that is not  tax-exempt.  The tax
equivalent  yield may be compounded  as described  above to provide a compounded
effective tax equivalent  yield. The tax equivalent yield may be used to compare
the tax  effects of income  derived  from the Trust  with  income  from  taxable
investments at the tax rates stated.  Appendix C includes a tax equivalent yield
table,  based on various effective tax brackets for individual  taxpayers.  Such
tax brackets are  determined by a taxpayer's  Federal and state  taxable  income
(the net amount  subject to Federal and state  income tax after  deductions  and
exemptions).  The tax equivalent  yield table assumes that the investor is taxed
at  the  highest  bracket,   regardless  of  whether  a  switch  to  non-taxable
investments  would  cause a lower  bracket to apply,  and that state  income tax
payments are fully deductible for income tax purposes. For taxpayers with income
above certain levels,  otherwise allowable itemized deductions are limited.  For
the seven-day period ended June 30, 1998, the Trust's  tax-equivalent  yield was
2.76%  and its  tax-equivalent  compounded  effective  yield  was  2.79%  for an
investment subject to a ___% combined effective tax rate.
    

      Yield  information  may be useful to investors  in  reviewing  the Trust's
performance.  The Trust's yield may be compared to that of other investments, by
citing various indices. However, a number of factors should be considered before
using yield  information as a basis for comparison  with other  investments.  An
investment in the Trust is not insured. Its yield is not guaranteed and normally
will  fluctuate on a daily basis.  The yield for any given past period is not an
indication or representation by the Trust of future yields or rates of return on
its shares.  The  Trust's  yield is affected  by  portfolio  quality,  portfolio
maturity,   type  of  instruments  held  and  operating  expenses.  The  Trust's
performance reflects the voluntary assumption of expenses by the Manager, absent
which such figures would have been lower than those shown above.  When comparing
the Trust's yield and investment risk 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 or yields that may vary above a stated
minimum, and also that bank accounts may be insured or guaranteed. Certain types
of bank  accounts may not pay interest  when the balance falls below a specified
level and may limit the number of  withdrawals  by check per month.  In order to
compare  the  Trust's  dividends  to the rate of return on taxable  investments,
federal and state income taxes on such investments should be considered.

ABOUT YOUR ACCOUNT

Purchase, Redemption and Pricing of Shares

   
Determination of Net Asset Value Per Share. The net asset value per share of the
Trust is  determined  twice each day, as of 12:00 Noon (all  references  to time
mean New York time) and 4:00 P.M., each day the The New York Stock Exchange (the
"Exchange")  is open (a  "regular  business  day") by  dividing  the Trust's net
assets  (the total  value of the Trust's  portfolio  securities,  cash and other
assets less all liabilities) by the total number of shares  outstanding.  Shares
of the Trust are sold at their offering price (net asset value,  without a sales
charge) as  described  in the  Prospectus.  The  Exchange's  most recent  annual
holiday  schedule  states that it will close New Year's Day,  Martin Luther King
Jr. Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence  Day, Labor
Day,  Thanksgiving  Day and Christmas  Day. The Exchange may also close on other
days.  Dealers  other than  Exchange  members may conduct  trading in  Municipal
Securities on certain days on which the Exchange is closed (e.g.,  Good Friday),
so that securities of the same type held by the Trust may be traded, and its net
asset  value  per  share  may be  significantly  affected,  on  such  days  when
shareholders may not purchase or redeem shares.

       The Trust's Board of Trustees has  established  procedures to comply with
Rule 2a-7 for the valuation of the Trust's securities,  which provide that money
market debt securities that have a
    

remaining  maturity of less than 397 days shall be valued at cost,  adjusted for
amortization of premiums and accretion of discounts;  and securities  (including
restricted securities) not having readily-available market quotations are valued
at fair value  determined under the Board's  procedures.  The Trust will seek to
maintain a net asset  value of $1.00 per share for  purchases  and  redemptions.
There can be no assurance  that the Trust will do so. The Trust  operates  under
Rule 2a-7 under which a trust may use the  amortized  cost method of valuing its
shares.  The amortized  cost method values a security  initially at its cost and
thereafter  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 account unrealized capital
gains or losses.

      The  Trust's  Board of Trustees  has  established  procedures  intended to
stabilize  the Trust's  net asset  value at $1.00 per share.  If the Trust's net
asset  value per share were to deviate  from $1.00 by more than 0.5%,  Rule 2a-7
requires the Board promptly to consider what action, if any, should be taken. If
the Trustees  find that the extent of any such  deviation may result in material
dilution or other unfair effects on  shareholders,  the Board will take whatever
steps it considers  appropriate  to eliminate or reduce such  dilution or unfair
effects,  including,  without limitation,  selling portfolio securities prior to
maturity,  shortening the average  portfolio  maturity,  withholding or reducing
dividends,  reducing the  outstanding  number of Trust shares  without  monetary
consideration,  or  calculating  net asset  value  per share by using  available
market quotations.

      As long as the Trust  uses Rule  2a-7,  the Trust  must  abide by  certain
conditions  described  in the  Prospectus.  Under Rule 2a-7,  the maturity of an
instrument is generally  considered to be its stated maturity (or in the case of
an instrument  called for redemption,  the date on which the redemption  payment
must be made),  with special  exceptions  for certain  variable  rate demand and
floating rate instruments.  Repurchase agreements and securities loan agreements
are,  in  general,  treated as having a maturity  equal to the period  scheduled
until repurchase or return, or if subject to demand, equal to the notice period.

   
     While the amortized cost method provides certainty in valuation,  there may
be periods during which the value of an  instrument,  as determined by amortized
cost,  is higher or lower than the price the Trust would  receive if it sold the
instrument.  During  periods of  declining  interest  rates,  the daily yield on
shares of the Trust may tend to be lower  (and net  investment  income and daily
dividends  higher)  than market  prices or  estimates  of market  prices for its
portfolio.  Thus, if the use of amortized  cost by the Trust resulted in a lower
aggregate  portfolio  value on a particular  day, a prospective  investor in the
Trusts  would be able to obtain a somewhat  higher  yield than would result from
investment in a fund utilizing solely market values,  and existing  investors in
the Trust would receive less investment  income than if the Trust were priced at
market value.  Conversely,  during periods of rising interest  rates,  the daily
yield on Trust shares will tend to be higher and its aggregate  value lower than
that of a portfolio priced at market value. A prospective investor would receive
a lower yield than from an  investment  in a portfolio  priced at market  value,
while existing  investors in the Trust would receive more investment income than
if the Trust were priced at market value.
    

Redemption of Shares. Information on how to redeem shares of the Trust is stated
in the  Prospectus.  The Prospectus  states that payment for shares tendered for
redemption  is  ordinarily  made in cash.  If,  however,  the Board of  Trustees
determines  that it would be  detrimental to the best interests of the remaining
shareholders  of the Trust to make payment wholly in cash, the redemption  price
may be paid in whole or in part by a distribution in kind of securities from the
portfolio  of the  Trust  in  lieu  of cash  or in  conformity  with  applicable
Securities and Exchange  Commission  rules. The Trust has elected to be governed
by Rule 18f-1 under the Investment  Company Act,  pursuant to which the Trust is
obligated to redeem  shares solely in cash up to the lesser of $250,000 or 1% of
the net assets of the Trust during any 90-day period for any one shareholder. If
shares are redeemed in kind, the redeeming  shareholder  might incur transaction
or other  costs  in  converting  the  assets  to cash.  The  method  of  valuing
securities  used to make  redemptions  in kind will be the same as the method of
valuing securities described under "Determination of Net Asset Value" above, and
such  valuation  will  be made as of the  same  time  the  redemption  price  is
determined.

      The Trust's Board of Trustees has the right, in conformity with applicable
law, to cause the  involuntary  redemption  of shares held in any account if the
aggregate net asset value of such shares is less than $200 or such lesser amount
as the Board may fix. Should the Board elect to exercise this right, it may also
fix, in accordance with the applicable law, the  requirements  for any notice to
be given to the  shareholder(s)  in question  (not less than 30 days) or may set
requirements  for permission to allow the shareholder to increase the investment
so that the shares would not be involuntarily redeemed.

Expedited  Redemption  Procedures.  Under  the  Expedited  Redemption  Procedure
discussed in the Prospectus, the wiring of redemption proceeds may be delayed if
the  Trust's  Custodian  bank is not open for  business  on a day that the Trust
would normally  authorize the wire to be made, which is usually the same day for
redemptions  prior to 12:00 Noon and the Trust's next  regular  business day for
redemptions between 12:00 Noon and the close of the Exchange,  which is normally
4:00 P.M.,  but may be earlier on some days.  In those  circumstances,  the wire
will not be  transmitted  until the next bank business day on which the Trust is
open for  business  and no  dividends  will be paid on the  proceeds of redeemed
shares awaiting transfer by wire.

Dividend  Reinvestment  in Another Fund.  Direct  shareholders  of the Trust may
elect to reinvest all dividends and/or distributions in Class A shares of any of
the other funds  listed  below as  "Eligible  Funds" at net asset value  without
sales charge. To elect this option, a shareholder must notify the Transfer Agent
in writing,  and either must have an existing  account in the fund  selected for
reinvestment or must obtain a prospectus for that fund and application  from the
Transfer Agent to establish an account.  The investment  will be made at the net
asset value per share next  determined  on the payable  date of the  dividend or
distribution.

   
Checkwriting.  Checkwriting  procedures  are  described  in the  Prospectus.  By
choosing  the  Checkwriting  privilege,  whether  done by  signing  the  Account
Application or by completing a Checkwriting  card, the  individuals  signing (1)
represent  that they are either  the  registered  owner(s)  of the shares of the
Trust, or are an officer,  general partner, trustee or other fiduciary or agent,
as applicable, duly authorized to act on behalf of such registered owner(s); (2)
authorize the Trust,  its Transfer  Agent and any bank through which the Trust's
drafts ("checks") are payable (the "Bank"), to pay all checks drawn on the Trust
account of such person(s) and to effect a redemption of sufficient shares in the
account to cover payment of such checks; (3) specifically acknowledge(s) that if
you choose to permit a single  signature on checks drawn against joint accounts,
or  accounts  for  corporations,  partnerships,  trusts or other  entities,  the
signature  of any one  signatory  on a check  will be  sufficient  to  authorize
payment of that check and  redemption  from an account  even if that  account is
registered  in the  names  of more  than  one  person  or even if more  than one
authorized  signature  appears on the Checkwriting  card or the Application,  as
applicable;  and  (4)  understand(s)  that  the  Checkwriting  privilege  may be
terminated or amended at any time by the Trust and/or the Bank and neither shall
incur  any  liability  for  such  amendment  or  termination  or  for  effecting
redemptions to pay checks reasonably believed to be genuine, or for returning or
not paying checks which have not been accepted for any reason.

Dividends, Distributions and Taxes

Tax  Status  of  the  Trust's  Dividends  and  Distributions.  The  Federal  and
California  tax  treatment  of  the  Trust's   dividends  and  distributions  to
shareholders  is explained in the  Prospectus  under the caption  "Dividends and
Taxes." Under the Internal Revenue Code, by December 31 each year the Trust must
distribute  (i) 98% of its  taxable  investment  income  earned  from  January 1
through  December 31 of that year, (ii) 98% of its capital gains realized in the
period from November 1 of the prior year through October 31 of the current year,
and (iii) the sum of any untaxed,  undistributed  net investment  income and net
capital gains from prior periods or else the Trust must pay a  nondeductible  4%
excise tax on the amounts not  distributed.  While it is  currently  anticipated
that the Trust's  distributions will meet those requirements,  the Trust's Board
and Manager might  determine in a particular  year that is in the best interests
of the Trust not to distribute  income or capital  gains at the mandated  levels
and to pay the excise tax on the undistributed amounts.

NOTES TO FINANCIAL STATEMENTS
Centennial California Tax Exempt Trust


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

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

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

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 Trust  concentrates its investments in California and,
therefore,  may have more credit  risks  related to the economic  conditions  of
California than a portfolio with a broader geographical diversification.

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

2.  SHARES OF BENEFICIAL INTEREST
The  Trust  has  authorized  an  unlimited  number  of no par  value  shares  of
beneficial  interest.  Transactions  in shares of  beneficial  interest  were as
follows:

</TABLE>




3.  MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES
Management  fees paid to the  Manager  were in  accordance  with the  investment
advisory agreement with the Trust which provides for a fee of 0.50% of the first
$250 million of net assets; 0.475% of the next $250 million of net assets; 0.45%
of the next $250  million of net assets;  0.425% of the next $250 million of net
assets  and  0.40% of net  assets  in  excess of $1  billion.  The  Manager  has
voluntarily  undertaken  to assume Trust  expenses in excess of 0.80% of average
annual net assets.

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

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

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

                                  APPENDIX A

                      DESCRIPTION OF SECURITIES RATINGS

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

Short Term Debt Ratings.

Moody's Investors Service, Inc.  ("Moody's"):  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 broadbased
               access to the market for refinancing.

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

Standard  &  Poor's  Corporation  ("S&P"):  The  following  ratings  by S&P  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+").

   
IBCA Fitch  ("Fitch"):  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. ("Duff & Phelps"):  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.  ("TBW"):  The following  short-term  ratings apply to
commercial paper, certificates of deposit, unsecured notes, and other securities
having a maturity of one year or less. 

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

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

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

Moody's:  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:  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.

Duff & Phelps: 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.

IBCA:  Long-term  obligations (with maturities of more than 12 months) are rated
as follows:

AAA:    The lowest expectation of investment risk. Capacity for timely repayment
        of principal and interest is  substantial  such that adverse  changes in
        business,  economic,  or financial  conditions  are unlikely to increase
        investment risk significantly.

AA: A very low expectation for investment risk. Capacity for timely repayment of
principal and interest is substantial. Adverse changes in business, economic, or
financial conditions may increase investment risk albeit not very significantly.

A plus (+) or minus (-) sign may be  appended  to a long  term  rating to denote
relative status within a rating category.

TBW: 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 category.

                                   TAX-EQUIVALENT YIELDS

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

                                  APPENDIX D


                     AUTOMATIC WITHDRAWAL PLAN PROVISIONS

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

      Trust shares will be redeemed as necessary  to meet  withdrawal  payments.
Shares  acquired  without a sales charge will be redeemed  first and  thereafter
shares acquired with reinvested  dividends and distributions  followed by shares
acquired  with a sales  charge will be redeemed to the extent  necessary to make
withdrawal  payments.  Depending  upon  the  amount  withdrawn,  the  investor's
principal may be depleted. Payments made to shareholders under such plans should
not be considered as a yield or income on an 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  approximately  three business
days prior to the date selected for receipt of the monthly or quarterly  payment
(the date of receipt is  approximate),  according  to the  choice  specified  in
writing by the Planholder.

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

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

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

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

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

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

Item 27.    Indemnification
- - --------    ---------------

      Reference is made to  paragraphs  (c) through (f) of Section 12 of Article
SEVENTH of Registrant's  Declaration of Trust, filed as Exhibit 24(b)(1) to this
registration statement.

      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.

2.    TAX  EQUIVALENT  CURRENT AND  EFFECTIVE  YIELDS FOR THE 7-DAY PERIOD ENDED
      06/30/97:

      The Fund's current tax equivalent  yield is calculated using the following
      formula:

                  a
               -----  +  b  =  Tax Equivalent Yield
               1 - c

      The symbols above represent the following factors:

      a   =  7-day  current  yield  of  tax-exempt  security  positions  in  the
          portfolio.
      b   = 7-day current yield of taxable security positions in the portfolio.
      c   = Combined  stated tax rate (e.g.,  federal and state income tax rates
          for an individual in the 39.6% federal tax bracket filing singly).


      Example:           .0324
                        ----------  +  0  =   5.91%
                        1  - .4522




      The  Fund's  effective  tax  equivalent  yield  is  calculated  using  the
      following formula:

                  a
               -----  +  b  =  Tax Equivalent Yield
               1 - c

      The symbols above represent the following factors:

      a   = 7-day  effective  yield  of  tax-exempt  security  positions  in the
          portfolio.
      b   =  7-day  effective  yield  of  taxable  security   positions  in  the
          portfolio.
      c   = Combined  stated tax rate (e.g.,  federal and state income tax rates
          for an individual in the 39.6% federal tax bracket filing singly).

      Example:            .0330
                        ----------  +  0  =   6.02%

3.    TAX  EQUIVALENT  CURRENT AND EFFECTIVE  YIELDS FOR THE 30-DAY PERIOD ENDED
      06/30/97:

      The Fund's current tax equivalent  yield is calculated using the following
      formula:

                  a
               -----  +  b  =  Tax Equivalent Yield
               1 - c

      The symbols above represent the following factors:

      a   =  30-day  current  yield  of  tax-exempt  security  positions  in the
          portfolio.
      b   = 30-day current yield of taxable security positions in the portfolio.
      c   = Combined  stated tax rate (e.g.,  federal and state income tax rates
          for an individual in the 39.6% federal tax bracket filing singly).

      Example:            .0305
                        ----------  +  0  =   5.57%
                        1  - .4522


      The  Fund's  effective  tax  equivalent  yield  is  calculated  using  the
      following formula:

                  a
               -----  +  b  =  Tax Equivalent Yield
               1 - c

      The symbols above represent the following factors:

      a   = 30-day  effective  yield of  tax-exempt  security  positions  in the
          portfolio.
      b = 30-day effective yield of taxable security positions in the

          portfolio.
      c   = Combined  stated tax rate (e.g.,  federal and state income tax rates
          for an individual in the 39.6% federal tax bracket filing singly).


      Example:            .0309
                        ----------  +  0  =   5.64%
                        1  - .4522



      Combined Stated Tax Rate Formula

            1 - {(1-d)(1-e)} = Combined Stated Tax Rate

      The symbols above represent the following factors:

      d   =  Stated  federal  tax rate  (e.g.,  federal  income  tax rate for an
          individual in the 39.6% federal tax bracket filing singly).
      e   = Stated  California  State tax rate (e.g.,  for an  individual in the
          39.6% federal and 9.30% state tax bracket filing singly).


      Example:   1 - {(1 - .3960)(1 - .0930)} =  45.22%
