The Trust's Investment Objective and Strategies

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

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

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

Main Risks of Investing in the Trust

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

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

The Trust's Past Performance

The bar chart and table below show how the Trust's returns may vary over time, by showing
changes in the Trust's performance from year to year for the last 10 calendar years and its
average annual total returns for the 1-, 5- and 10- year periods. Variability of returns is
one measure of the risks of investing in a money market fund. The Trust's past investment
performance does not predict how the Trust will perform in the future.

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

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

For the period from 1/1/06 through 6/30/06 the cumulative total return (not annualized) was
2.06%.
During the period shown in the bar chart, the highest return (not annualized) for a
calendar quarter was 1.54% (4th Q `00) and the lowest return (not annualized) for a
calendar quarter was 0.11% (1st Q'04 & 2ndQ `04).

Fees and Expenses of the Trust

The Trust pays a variety of expenses directly for management of its assets, administration
and other services. Those expenses are subtracted from the Trust's assets to calculate the
Trust's net asset value per share. All shareholders therefore pay those expenses
indirectly. The following tables are meant to help you understand the fees and expenses you
may pay if you buy and hold shares of the Trust. The numbers below are based upon the
Trust's expenses during its fiscal year ended June 30, 2006.

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

Annual Trust Operating Expenses (deducted from Trust assets):

------------------------------------------------------------------------------
Total Annual Operating Expenses 0.67%
------------------------------------------------------------------------------
Expenses may vary in future years. "Other Expenses" include transfer agent fees, custodial
expenses, and accounting and legal expenses the Trust pays. The Transfer Agent has
voluntarily undertaken to the Trust to limit the transfer agent fees to 0.35% of average
daily net assets per fiscal year. That undertaking may be amended or withdrawn at any time.
For the Trust's fiscal year ended June 30, 2006, the transfer agent fees did not exceed the
expense limitation described above.

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

About the Trust's Investments

THE TRUST'S PRINCIPAL INVESTMENT POLICIES AND RISKS. The Trust invests in money market
instruments meeting quality, maturity and diversification standards established by its
Board of Trustees as well as rules that apply to money market funds under the Investment
Company Act of 1940 ("Investment Company Act"). The Statement of Additional Information
("SAI") contains more detailed information about the Trust's investment policies and risks.

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

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

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

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

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

o Corporate Debt Obligations. The Trust can invest in other short-term corporate debt
obligations. Please see "What Standards Apply to the Trust's Investments?" below for
more details.

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

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

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

What Standards Apply to the Trust's Investments? Money market instruments are subject to
credit risk, the risk that the issuer might not make timely payments of interest on
the security or repay principal when it is due. The Trust can buy only those
instruments that meet standards set by the Investment Company Act for money market
funds and procedures adopted by the Board of Trustees. The Trust's 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, the Trust buys only high-quality investments that the Manager believes
present minimal credit risk at the time of purchase. "High-quality" investments are:

o rated in one of the two highest short-term rating categories of two national rating
organizations, or
o rated by one rating organization in one of its two highest rating categories (if only
one rating organization has rated the investment), or
o unrated investments that the Manager determines are comparable in quality to the two
highest rating categories.

The procedures also limit the amount of the Trust's assets that can be invested in
the securities of any one issuer (other than the U.S. government, its agencies and
instrumentalities), to spread the Trust's investment risks. No security's maturity
will exceed the maximum time permitted under Rule 2a-7 (currently 397 days).
Finally, the Trust must maintain a dollar-weighted average portfolio maturity of not
more than 90 days, to reduce interest rate risks.

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

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

Floating Rate/Variable Rate Notes. The Trust can purchase investments with floating or
variable interest rates. Variable rates are adjustable at stated periodic
intervals. Floating rates are adjusted automatically according to a specified market
rate or benchmark for such investments, such as the prime rate of a bank. If the
maturity of an investment is greater than the maximum time permitted under Rule 2a-7
(currently 397 days), it can be purchased if it has a demand feature. That feature
must permit the Trust to recover the principal amount of the investment on not more
than 30 days' notice at any time, or at specified times not exceeding the maximum
time permitted under Rule 2a-7.

Asset-Backed Securities. The Trust can invest in asset-backed securities. These are
fractional interests in pools of consumer loans and other trade receivables, which
are the obligations of a number of different parties. The income from the underlying
pool is passed through to investors, such as the Trust. These investments might be
supported by a credit enhancement, such as a letter of credit, a guarantee or a
preference right. However, the credit enhancement generally applies only to a
fraction of the security's value. If the issuer of the security has no security
interest in the related collateral, there is the risk that the Trust could lose money
if the issuer defaults.

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

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

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

Illiquid and Restricted Securities. Investments may be illiquid because they do not have
an active trading market, making it difficult to value them or dispose of them
promptly at an acceptable price. Restricted securities may have terms that limit
their resale to other investors or may require registration under applicable
securities laws before they may be sold publicly. The Trust will not invest more
than 10% of its net assets in illiquid securities. The Trust may invest up to 25% of
its net assets in restricted securities, subject to the 10% limit on illiquid
securities and restricted securities other than those sold to qualified institutional
purchasers. That limit does not apply to certain restricted securities that are
eligible for resale to qualified institutional purchasers or purchases of commercial
paper that may be sold without registration under the federal securities laws. The
Manager monitors holdings of illiquid securities on an ongoing basis to determine
whether to sell any holdings to maintain adequate liquidity. Difficulty in selling a
security may result in a loss to the Trust or additional costs.

PORTFOLIO HOLDINGS. The Trust's portfolio holdings are included in semi-annual and annual
reports that are distributed to shareholders of the Trust within 60 days after the
close of the period for which such report is being made. The Trust discloses its
portfolio holdings in its Statement of Investments on Form N-Q, which are filed with
the Securities and Exchange Commission (the "SEC") no later than 60 days after the
close of its first and third fiscal quarters. These required filings are publicly
available at the SEC. Therefore, portfolio holdings of the Trust are made publicly
available no later than 60 days after the close of the Trust's fiscal quarters.

A description of the Trust's policies and procedures with respect to the disclosure
of the Trust's portfolio securities is available in the Trust's SAI.

The Trust's Investment Objective and Strategies

WHAT IS THE TRUST'S INVESTMENT OBJECTIVE? The Trust seeks the maximum short-term interest
income exempt from federal income taxes that is consistent with low capital risk and the
maintenance of liquidity.

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

The Trust normally invests 100% of its assets in municipal securities. As a
fundamental policy, the Trust will invest under normal circumstances at least 80% of its
net assets (plus any borrowings for investment purposes) in securities investments the
income from which is exempt from federal income taxes. Securities that generate income that
is subject to alternative minimum taxes will not count towards that 80% threshold. The
balance of the Trust's assets can be invested in investments the income from which may be
taxable. The Trust will not invest more than 20% of its net assets in municipal securities
the income on which may be a tax preference item that would increase an individual
investor's alternative minimum tax.

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

Main Risks of Investing in the Trust

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

The Trust's Past Performance

The bar chart and table below show how the Trust's returns may vary over time, by showing
changes in the Trust's performance from year to year for the last 10 calendar years and
average annual total returns for the 1-, 5- and 10- year periods. Variability of returns is
one measure of the risks of investing in a money market fund. The Trust's past investment
performance does not predict how the Trust will perform in the future.

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

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

For the period from 1/1/06 through 6/30/06 the cumulative total return (not annualized) was
1.37%.
During the period shown in the bar chart, the highest return (not annualized) for a
calendar quarter was 0.91% (4th Q '00) and the lowest return for a calendar quarter (not
annualized) was 0.08% (3rd Q '03 & 1st Q `04).

About the Trust's Investments

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

o Municipal Securities. The Trust buys municipal bonds and notes, tax-exempt
commercial paper, certificates of participation in municipal leases and other debt
obligations. These are debt obligations issued by the governments of states, their
political subdivisions (such as cities, towns and counties), or the District of
Columbia, their political subdivisions (such as cities, towns and counties, or any
commonwealth or territory of the United States, or by their agencies,
instrumentalities and authorities, if the interest paid on the security is not
subject to federal individual income tax in the opinion of bond counsel to the
issuer. All of these types of debt obligations are referred to as "municipal
securities" in this Prospectus.

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

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

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

The procedures also limit the amount of the Trust's assets that can be invested in
the securities of any one issuer (other than the U.S. government, its agencies and
instrumentalities), to spread the Trust's investment risks. The Trust must also maintain a
dollar-weighted average portfolio maturity of not more than 90 days, to reduce interest
rate risks. Additionally, the remaining maturity of any single portfolio investment may
not exceed the maximum time permitted under Rule 2a-7 (currently 397 days).

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

Floating Rate/Variable Rate Notes. The Trust can purchase investments with floating or
variable interest rates. Variable rates are adjustable at stated periodic
intervals. Floating rates are adjusted automatically according to a specified market
rate or benchmark for such investment, such as the prime rate of a bank. If the
maturity of an investment is greater than the maximum time permitted under Rule 2a-7
(currently 397 days), it can be purchased if it has a demand feature. That feature
must permit the Trust to recover the principal amount of the investment on not more
than 30 days' notice at any time, or at specified times not exceeding the maximum
time permitted under Rule 2a-7 (currently 397 days) from the date of purchase.

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

Municipal Lease Obligations. Municipal leases are used by state and local governments to
obtain funds to acquire land, equipment or facilities. The Trust can invest in
certificates of participation that represent a proportionate interest in payments
made under municipal lease obligations. Most municipal leases, while secured by the
leased property, are not general obligations of the issuing municipality. They often
contain "non-appropriation" clauses under which the municipal government has no
obligation to make lease or installment payments in future years unless money is
appropriated on a yearly basis. If the government stops making payments or transfers
its payment obligations to a private entity, the obligation could lose value or
become taxable. Some of these obligations might not have an active trading market
and would be subject to the Trust's limits on "illiquid" securities described below.
From time to time the Trust can 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.

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

Illiquid and Restricted Securities. Investments may be illiquid because they do not have
an active trading market, making it difficult to value them or dispose of them
promptly at an acceptable price. Restricted securities may have terms that limit
their resale to other investors or may require registration under applicable
securities laws before they may be sold publicly. The Trust will not invest more
than 10% of its net assets in illiquid securities. That limit does not apply to
certain restricted securities that are eligible for resale to qualified institutional
purchasers or purchases of commercial paper that may be sold without registration
under the federal securities laws. The Manager monitors holdings of illiquid
securities on an ongoing basis to determine whether to sell any holdings to maintain
adequate liquidity. Difficulty in selling a security may result in a loss to the
Trust or additional costs.

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

Temporary Defensive and Interim Investments. In times of unstable adverse market,
political or economic conditions, the Trust can invest up to 100% of its assets in
temporary or interim investments that are inconsistent with the Trust's principal
investment strategies. These temporary investments can include:
o obligations issued or guaranteed by the U.S. government or its agencies or
instrumentalities,
o bankers' acceptances; taxable commercial paper rated in the highest category by a
rating organization,
o short-term taxable debt obligations rated in one of the two highest rating categories
of a rating organization,
o certificates of deposit of domestic banks, and
o repurchase agreements.

To the extent the Trust assumes a temporary defensive position; a significant portion
of the Trust's distributions may be taxable.

PORTFOLIO HOLDINGS. The Trust's portfolio holdings are included in semi-annual and annual
reports that are distributed to shareholders of the Trusts within 60 days after the close
of the period for which such report is being made. The Trust also discloses its portfolio
holdings in its Statements of Investments on Form N-Q, which are filed with the SEC no
later than 60 days after the close of its first and third fiscal quarters. These required
filings are publicly available at the Securities and Exchange Commission (the "SEC").
Therefore, portfolio holdings of the Trust are made publicly available no later than 60
days after the close of the Trust's fiscal quarters.

A description of the Trust's policies and procedures with respect to the disclosure of the
Trust's portfolio securities is available in the Trust's Statements of Additional
Information.

Centennial Government Trust

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

Prospectus dated August 23 ,2006
Centennial Government Trust is a money
market mutual fund. It seeks a high
level of current income consistent
with preserving capital and
maintaining liquidity. The Trust
invests in short-term, high-quality
"money market" investments.

A B O U T T H E T R U S T

The Trust's Investment Objective and Strategies

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

WHAT DOES THE TRUST MAINLY INVEST IN? The Trust is a money market fund. It invests in a
variety of high-quality money market instruments to seek income. The Trust invests
principally in short-term, U.S. dollar denominated debt instruments issued by the U.S.
government, its agencies and instrumentalities. To be considered "high-quality," generally
they must be rated in one of the two highest credit-quality categories for short-term
securities by nationally recognized rating services. If unrated, a security must be
determined by the Trust's investment manager to be of comparable quality to rated
securities. Many of the securities issued by the U.S. government are not rated, but the
Trust may purchase them because they meet the "high quality" standards of the Trust.

The Trust will invest under normal circumstances at least 80% of its net assets (plus
any borrowings for investment purposes) in debt instruments issued by the U.S. government,
its agencies and instrumentalities. Although this is not a fundamental policy, the amount
so invested will not be changed by the Board without providing shareholders at least 60
days prior notice of the change.

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

Main Risks of Investing in the Trust

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

The Trust's Past Performance

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

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

For the period from 1/1/06 through 6/30/06 the cumulative total return (not annualized) was
1.98%.
During the period shown in the bar chart, the highest return (not annualized) for a
calendar quarter was 1.48%
(4th Q'00) and the lowest return (not annualized) for a calendar quarter was 0.09% (2nd Q
'04)).

Fees and Expenses of the Trust

The Trust pays a variety of expenses directly for management of its assets, administration
and other services. Those expenses are subtracted from the Trust's assets to calculate the
Trust's net asset value per share. All shareholders therefore pay those expenses
indirectly. The following tables are meant to help you understand the fees and expenses
you may pay if you buy and hold shares of the Trust. The numbers below are based upon the
Trust's expenses during its fiscal year ended June 30, 2006.

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

------------------------------------------------------------------------------
Management Fees 0.45%

Other Expenses 0.09%

------------------------------------------------------------------------------
Total Annual Operating Expenses 0.74%
------------------------------------------------------------------------------
Expenses may very in future years. "Other Expenses" include transfer agent fees, custodial
expenses, and accounting and legal expenses the Trust pays. The Transfer Agent has
voluntarily undertaken to the Trust to limit the transfer agent fees to 0.35% of average
daily net assets per fiscal year. That undertaking may be amended or withdrawn at any
time. For the Trust's fiscal year ended June 30, 2006, the transfer agent fees did not
exceed the expense limitation described above.

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

About the Trust's Investments

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

o U.S. Government Securities. The Trust invests mainly in obligations issued or
guaranteed by the U.S. government or any of its agencies or instrumentalities. Some
are direct obligations of the U.S. Treasury, such as Treasury bills, notes and bonds,
and are supported by the full faith and credit of the United States. Although these
U.S. Government Securities are not rated, they are "high quality" investments under
the rules that apply to money market funds. Other U.S. government securities, such
as pass-through certificates issued by the Government National Mortgage Association
(Ginnie Mae), are also supported by the full faith and credit of the U.S.
government. Some government securities, agencies or instrumentalities of the U.S.
government are supported by the right of the issuer to borrow from the U.S. Treasury,
such as securities of the Federal National Mortgage Association (Fannie Mae). Others
may be supported only by the credit of the instrumentality, such as obligations of
the Federal Home Loan Mortgage Corporation (Freddie Mac).

o Other Money Market Instruments. The Trust can invest in variable or floating rate
notes, variable rate master demand notes or in master demand notes. The Trust can
also purchase other debt obligations with a length of permitted maturity up to the
maximum permitted under Rule 2a-7 (currently 397 days) from the date of purchase. It
may purchase debt obligations that have been called for redemption by the issuer if
the redemption will occur within the length of permitted maturity up to the maximum
permitted under Rule 2a-7 (currently 397 days). Please refer to "What Standards Apply
to the Trust's Investments?" below for more details.

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

In general, the Trust buys only high-quality investments that the Manager believes present
minimal credit risk at the time of purchase. The Trust invests mainly in obligations issued
or guaranteed by the U.S. Government and any of its agencies or instrumentalities.
"High-quality" investments are:

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. According to the standards,
the Trust can invest without limit in U.S. government securities because of their limited
investment risks. No security's maturity will exceed the maximum time permitted under Rule
2a-7 (currently 397 days). Finally, the Trust must maintain a dollar-weighted average
portfolio maturity of not more than 90 days, to reduce interest rate risks.

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

Floating Rate/Variable Rate Notes. The Trust can purchase investments with floating or
variable interest rates. Variable rates are adjustable at stated periodic
intervals. Floating rates are adjusted automatically according to a specified market
rate or benchmark for such investment, such as the prime rate of a bank. If the
maturity of an investment is greater than the maximum time permitted under Rule 2a-7
(currently 397 days), it can be purchased if it has a demand feature. That feature
must permit the Trust to recover the principal amount of the investment on not more
than 30 days' notice at any time, or at specified times not exceeding the maximum
time permitted under Rule 2a-7 (currently 397 days).

Illiquid and Restricted Securities. Investments may be illiquid because they do not have an
active trading market, making it difficult to value them or dispose of them promptly
at an acceptable price. Restricted securities may have terms that limit their
resale to other investors or may require registration under applicable securities
laws before they may be sold publicly. The Trust will not invest more than 10% of its
net assets in illiquid securities. That limit does not apply to certain restricted
securities that are eligible for resale to qualified institutional purchasers or
purchases of commercial paper that may be sold without registration under the federal
securities laws. The Manager monitors holdings of illiquid securities on an ongoing
basis to determine whether to sell any holdings to maintain adequate liquidity.
Difficulty in selling a security may result in a loss to the Trust or additional
costs.

PORTFOLIO HOLDINGS. The Trust's portfolio holdings are included in semi-annual and annual
reports that are distributed to shareholders of the Trust within 60 days after the
close of the period for which such report is being made. The Trust discloses its
portfolio holdings in its Statement of Investment on Form N-Q, which is filed with
the SEC no later than 60 days after the close of their first and third fiscal
quarters. These required filings are publicly available at the Securities and
Exchange Commission (the "SEC"). Therefore, portfolio holdings of the Trust are made
publicly available no later than 60 days after the close of the Trust's fiscal
quarters.

A description of the Trust's policies and procedures with respect to the disclosure
of the Trust's portfolio securities is available in the Trust's SAI.

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

How the Trusts are Managed

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

The Manager has been an investment advisor since 1978. The Manager and its parent
company and controlled affiliates managed more than $215 billion in assets as of June 30,
2006, including other Oppenheimer and Centennial funds with more than 6 million shareholder
accounts. The Manager is located at 6803 South Tucson Way, Centennial, Colorado 80112.

Advisory Fees. Under each investment advisory agreement, a Trust pays the Manager an
advisory fee at an annual rate that declines on additional assets as the Trust
grows. That fee is computed on the net assets of the respective Trust as of the
close of each business day.

o Centennial Money Market Trust. The annual management fee rates are: 0.500% of the
first $250 million of the Trust's net assets, 0.475% of the next $250 million, 0.450%
of the next $250 million, 0.425% of the next $250 million, 0.400% of the next $250
million, 0.375% of the next $250 million, 0.350% of the next $500 million, and 0.325%
of net assets in excess of $2 billion. The Trust's management fees for its fiscal
year ended June 30, 2006, were 0.33% of the Trust's average annual net assets.

o Centennial Government Trust. The annual management fee rates are: 0.500% of the
first $250 million of the Trust's net assets, 0.475% of the next $250 million, 0.450%
of the next $250 million, 0.425% of the next $250 million, 0.400% of the next $250
million, 0.375% of the next $250 million, 0.350% of net assets in excess of $1.5
billion. The Trust's management fees for its fiscal year ended June 30, 2006 were
0.45% of the Trust's average annual net assets.

o Centennial Tax-Exempt Trust. The annual management fee rates are: 0.500% of the
first $250 million of the Trust's net assets, 0.475% of the next $250 million, 0.450%
of the next $250 million, 0.425% of the next $250 million, 0.400% of the next $250
million, 0.375% of the next $250 million, 0.350% of the next $500 million, and 0.325%
of net assets in excess of $2 billion. Under the agreement, when the value of the
Trust's net assets is less than $1.5 billion, the annual fee payable to the Manager
shall be reduced by $100,000 based on average net assets computed daily and paid
monthly at the annual rates. However, the annual fee cannot be less than $0. The
Trust's management fees for its fiscal year ended June 30, 2006, were 0.43% of the
Trust's average annual net assets.

A discussion of the matters considered by the Trusts' Independent Trustees, in
approving the Trusts' Investment Advisory Agreements, is included in the Trusts'
annual report to shareholders for the period ended June 30, 2006.

Portfolio Managers. The portfolio managers of the Trusts are the persons principally
responsible for the day-to-day management of the Trusts' portfolios. The portfolio
managers of Centennial Money Market Trust and Centennial Government Trust are Carol
E. Wolf and Barry D. Weiss. Ms. Wolf has had this responsibility since November 1988
for Centennial Government Trust and October 1990 for Centennial Money Market Trust
and Mr. Weiss, since August 2001. Each is an officer of Centennial Money Market Trust
and Centennial Government Trust. Ms. Wolf is a Senior Vice President and Mr. Weiss
is a Vice President of the Manager, and each is an officer and portfolio manager of
other funds for which the Manager or an affiliate serves as investment advisor.
Prior to joining the Manager as Senior Credit Analyst in February, 2000, Mr. Weiss
was an Associate Director, Fitch IBCA Inc. (April 1998 - February 2000). The
portfolio manager of Centennial Tax Exempt Trust is Cameron T. Ullyatt (since July
2006). Mr. Ullyatt, CFA, has been a portfolio manager of the Trust since July 2006.
He has been a Vice President of the Manager and OppenheimerFunds, Inc. since July
2006. Mr. Ullyatt previously worked as an Assistant Vice President since December
2000 and analyst for the Manager and OppenheimerFunds, Inc. since January 1999.

The SAI provides additional information about the portfolio managers' compensation,
other accounts they manage and their ownership of Trust shares.

How to Buy Shares

AT WHAT PRICE ARE SHARES SOLD? Shares of each Trust are sold at their offering price,
which is the net asset value per share without any sales charge. The net asset value per
share will normally remain fixed at $1.00 per share. However, there is no guarantee that a
Trust will maintain a stable net asset value of $1.00 per share.

The offering price that applies to a purchase order is based on the next calculation
of the net asset value per share that is made after the Distributor (Centennial Asset
Management Corporation) or the Sub-Distributor (OppenheimerFunds Distributor, Inc.)
receives the purchase order at its offices in Colorado, or after any agent appointed by the
Sub-Distributor receives the order and sends it to the Sub-Distributor as described below.
Your financial adviser can provide you with more information regarding the time you must
submit your purchase order and whether the adviser is an authorized agent for the receipt
of purchase orders.

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

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

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

If, after the close of the principal market on which a security held by the Trusts is
traded, and before the time the Trusts' securities are priced that day, an event occurs
that the Manager deems likely to cause a material change in the value of such security, the
Trusts' Board of Trustees has authorized the Manager, subject to the Board's review, to
ascertain a fair value for such security. A security's valuation may differ depending on
the method used for determining value.

HOW MUCH MUST YOU INVEST? You can open an account with a minimum initial investment
described below, depending on how you buy and pay for your shares. You can make additional
purchases at any time with as little as $25. The minimum investment requirements do not
apply to reinvesting distributions from a Trust or other eligible funds (a list of them
appears in the SAI, or you can ask your broker/dealer or call the Transfer Agent) or
reinvesting distributions from unit investment trusts that have made arrangements with the
Distributor.

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

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

Buying Shares Through Your Broker/Dealer. If you do not participate in an Automatic
Purchase and Redemption Program, you can buy shares of a Trust through any
broker/dealer that has a sales agreement with the Distributor or Sub-Distributor.
Your broker/dealer will place your order with the Distributor on your behalf. A
broker/dealer may charge for that service.

Buying Shares Directly Through the Sub-Distributor. You can also purchase shares directly
through the Trusts' Sub-Distributor. Shareholders who make purchases directly and
hold shares in their own names, or who purchase shares through a broker/dealer and
hold shares in their own names are referred to as "direct shareholders" in this
Prospectus.

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

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

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

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

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

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

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

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

Payment by Check. Direct shareholders may pay for purchases of shares of a Trust by check.
Send your check, payable to "OppenheimerFunds Distributor, Inc.," along with your
application and other documents to the address listed above. Your check must be
payable in U.S. dollars and drawn on a U.S. bank. Distributions will begin to accrue
on the next regular business day after the Sub-Distributor accepts your purchase
order. The minimum initial investment for direct shareholders by check is $500.

Payment by Federal Funds Wire. Direct shareholders may pay for purchases of shares of a
Trust by Federal Funds wire. You must also forward your application and other
documents to the address listed above. Before sending a wire, call the
Sub-Distributor's Wire Department at 1.800.525.9310 (toll-free from within the U.S.)
or 303.768.3200 (from outside the U.S.) to notify the Sub-Distributor of the wire,
and to receive further instructions.

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

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

Service (12b-1) Plans. Each Trust has adopted a service plan. It reimburses the
Distributor for a portion of its costs incurred for services provided to accounts
that hold shares of a Trust. Reimbursement is made periodically depending on asset
size, at an annual rate of up to 0.20% of the average annual net assets of the Trust.
The Distributor currently uses all of those fees (together with significant amounts
from the Manager's own resources) to pay dealers, brokers, banks and other financial
institutions periodically for providing personal services and maintenance of accounts
of their customers that hold shares of the Trust.

OTHER PAYMENTS TO FINANCIAL INTERMEDIARIES AND SERVICE PROVIDERS. The Manager, the
Distributor and the Sub-Distributor in their discretion, also may pay dealers or other
financial intermediaries and service providers for distribution and/or shareholder
servicing activities. These payments are made out of the Manager's and/or the Distributor's
and/or the Sub-Distributor's own resources, including from the profits derived from the
advisory fees the Manager receives from the Trusts. These cash payments, which may be
substantial, are paid to many firms having business relationships with the Manager, the
Distributor and the Sub-Distributor. These payments are in addition to any distribution
fees, servicing fees, or transfer agency fees paid directly or indirectly by the Trusts to
these financial intermediaries. These payments by the Manager, the Distributor or the
Sub-Distributor from their own resources are not reflected in the tables in the section
called "Fees and Expenses of the Trust" in this Prospectus because they are not paid by the
Trusts.

"Financial intermediaries" are firms that offer and sell Trust shares to their
clients, or provide shareholder services to the Trusts, or both, and receive compensation
for doing so. Your securities dealer or financial adviser, for example, is a financial
intermediary, and there are other types of financial intermediaries that receive payments
relating to the sale or servicing of the Trusts' shares. In addition to dealers, the
financial intermediaries that may receive payments include sponsors of fund "supermarkets,"
sponsors of fee-based advisory or wrap fee programs, sponsors of college and retirement
savings programs, banks and trust companies offering products that hold Trust shares, and
insurance companies that offer variable annuity or variable life insurance products.

In general, these payments to financial intermediaries can be categorized as
"distribution-related" or "servicing" payments. Payments for distribution-related expenses,
such as marketing or promotional expenses, are often referred to as "revenue sharing."
Revenue sharing payments may be made on the basis of the sales of shares attributable to
that dealer, the average net assets of the Trusts and other Oppenheimer funds attributable
to the accounts of that dealer and its clients, negotiated lump sum payments for
distribution services provided, or sales support fees. In some circumstances, revenue
sharing payments may create an incentive for a dealer or financial intermediary or its
representatives to recommend or offer shares of the Trusts or other Oppenheimer funds to
its customers. These payments also may give an intermediary an incentive to cooperate with
the Distributor's or the Sub-Distributor's marketing efforts. A revenue sharing payment
may, for example, qualify the Trusts for preferred status with the intermediary receiving
the payment or provide representatives of the Distributor or the Sub-Distributor with
access to representatives of the intermediary's sales force, in some cases on a
preferential basis over funds of competitors. Additionally, as firm support, the Manager,
the Distributor or the Sub-Distributor may reimburse expenses related to educational
seminars and "due diligence" or training meetings (to the extent permitted by applicable
laws or the rules of the NASD) designed to increase sales representatives' awareness about
the Trusts and Oppenheimer funds, including travel and lodging expenditures. However, the
Manager does not consider a financial intermediary's sale of shares of the Trusts or other
Oppenheimer funds when selecting brokers or dealers to effect portfolio transactions for
the funds.

Various factors are used to determine whether to make revenue sharing payments.
Possible considerations include, without limitation, the types of services provided by the
intermediary, sales of a Trust's shares, the redemption rates on accounts of clients of the
intermediary or overall asset levels of the Trusts or Oppenheimer funds held for or by
clients of the intermediary, the willingness of the intermediary to allow the Distributor
or the Sub-Distributor to provide educational and training support for the intermediary's
sales personnel relating to the Trusts or the Oppenheimer funds, the availability of the
Trusts or the Oppenheimer funds on the intermediary's sales system, as well as the overall
quality of the services provided by the intermediary and the Manager, the Distributor or
the Sub-Distributor's relationship with the intermediary. The Manager, the Distributor and
the Sub-Distributor have adopted guidelines for assessing and implementing each prospective
revenue sharing arrangement. To the extent that financial intermediaries receiving
distribution-related payments from the Manager, the Distributor or the Sub-Distributor sell
more shares of the Trusts or the Oppenheimer funds or retain more shares of the funds in
their client accounts, the Manager, the Distributor, and the Sub-Distributor benefit from
the incremental management and other fees they receive with respect to those assets.

Payments may also be made by the Manager, the Distributor and the Sub-Distributor or
the Transfer Agent to financial intermediaries to compensate or reimburse them for
administrative or other client services provided such as sub-transfer agency services for
shareholders or retirement plan participants, omnibus accounting or sub-accounting,
participation in networking arrangements, account set-up, recordkeeping and other
shareholder services. Payments may also be made for administrative services related to the
distribution of Trust shares through the intermediary. Firms that may receive servicing
fees include retirement plan administrators, qualified tuition program sponsors, banks and
trust companies, and others. These fees may be used by the service provider to offset or
reduce fees that would otherwise be paid directly to them by certain account holders, such
as retirement plans.

The SAI contains more information about revenue sharing and service payments made by
the Manager, the Distributor or the Sub-Distributor. Your dealer may charge you fees or
commissions in addition to those disclosed in this Prospectus. You should ask your dealer
or financial intermediary for details about any such payments it receives from the Manager,
the Distributor or the Sub-Distributor and their affiliates, or any other fees or expenses
it charges.

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

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

How to Sell Shares

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

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

HOW CAN DIRECT SHAREHOLDERS REDEEM SHARES? Direct shareholders can redeem their shares by
writing a letter to the Transfer Agent, by wire, by using a Trust's checkwriting privilege,
or by telephone. You can also set up Automatic Withdrawal Plans to redeem shares on a
regular basis. If you have questions about any of these procedures, and especially if you
are redeeming shares in a special situation, such as due to the death of the owner or from
a retirement plan account, please call the Transfer Agent first, at 1.800.525.9310 for
assistance.

Certain Requests Require a Signature Guarantee. To protect you and the Trusts from fraud,
the following redemption requests for accounts of direct shareholders must be in
writing and must include a signature guarantee (although there may be other
situations that also require a signature guarantee):
o You wish to redeem more than $100,000 and receive a check.
o The redemption check is not payable to all shareholders listed on the account
statement.
o The redemption check is not sent to the address of record on your account statement.
o Shares are being transferred to an account with a different owner or name.
o Shares are being redeemed by someone (such as an Executor) other than the owners
listed in the account registration.

Where Can Direct Shareholders Have Their Signatures Guaranteed? The Transfer Agent will
accept a guarantee of your signature by a number of financial institutions,
including:
o a U.S. bank, trust company, credit union or savings association,
o a foreign bank that has a U.S. correspondent bank,
o a U.S. registered dealer or broker in securities, municipal securities or government
securities, or
o a U.S. national securities exchange, a registered securities association or a
clearing agency.

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

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

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

How Can Direct Shareholders Sell Shares by Telephone? Direct shareholders and their
broker/dealer representative of record may also sell shares by telephone. To receive
the redemption price calculated on a particular regular business day, the Transfer
Agent or its designated agent must receive the request by 4:00 p.m. on that day. You
may not redeem shares held under a share certificate or in certain retirement
accounts by telephone. To redeem shares through a service representative, call
1.800.525.9310. Proceeds of telephone redemptions will be paid by check payable to
the shareholder(s) of record and will be sent to the address of record for the
account. Up to $100,000 may be redeemed by telephone in any seven-day period. This
service is not available within 30 days of changing the address on an account.

Retirement Plan Accounts. There are special procedures to sell shares held in a retirement
plan account. Call the Transfer Agent for a distribution request form. Special income
tax withholding requirements apply to distributions from retirement plans. You must
submit a withholding form with your redemption request to avoid delay in getting your
money and if you do not want tax withheld. If your employer holds your retirement
plan account for you in the name of the plan, you must ask the plan trustee or
administrator to request the sale of the Trust shares in your plan account.

Sending Redemption Proceeds By Wire. While the Transfer Agent normally sends direct
shareholders their money by check, you can arrange to have the proceeds of the shares
you sell sent by Federal Funds wire to a bank account you designate. It must be a
commercial bank that is a member of the Federal Reserve wire system. The minimum
redemption you can have sent by wire is $2,500. There is a $10 fee for each request.
To find out how to set up this feature on an account or to arrange a wire, direct
shareholders should call the Transfer Agent at 1.800.525.9310. If you hold your
shares through your broker/dealer's Automatic Purchase and Redemption Program, you
must contact your broker/dealer to arrange a Federal Funds wire.

Can Direct Shareholders Submit Requests by Fax? Direct shareholders may send requests for
certain types of account transactions to the Transfer Agent by fax (telecopier).
Please call 1.800.525.9310 for information about which transactions may be handled
this way. Transaction requests submitted by fax are subject to the same rules and
restrictions as written and telephone requests described in this Prospectus.

HOW DO I WRITE CHECKS AGAINST MY ACCOUNT? Automatic Purchase and Redemption Program
participants may write checks against an account held under their Program, but must arrange
for checkwriting privileges through their broker/dealers. Direct shareholders may write
checks against their account by requesting that privilege on the account application or by
contacting the Transfer Agent for signature cards. They must be signed (with a signature
guarantee) by all owners of the account and returned to the Transfer Agent so that checks
can be sent to you to use. Shareholders with joint accounts can elect in writing to have
checks paid over the signature of one owner. If checkwriting is established after November
1, 2000, only one signature is required for shareholders with joint accounts, unless you
elect otherwise.

o Checks can be written to the order of whomever you wish, but may not be cashed at the
bank the checks are payable through or the Trusts' custodian bank.
o Checkwriting privileges are not available for accounts holding shares that are
subject to a contingent deferred sales charge.
o Checks must be written for at least $250.
o Checks cannot be paid if they are written for more than your account value.
o You may not write a check that would require the Trusts to redeem shares that were
purchased by check or Automatic Investment Plan payments within the prior 10 days.
o Don't use your checks if you changed your account number, until you receive new
checks.

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

o if you acquired shares of a Trust by exchanging Class A shares of another eligible
fund that you bought subject to the Class A contingent deferred sales charge, and
o those shares are still subject to the Class A contingent deferred sales charge when
you exchange them into the Trust, then
o you will pay the contingent deferred sales charge if you redeem those shares from the
Trust within 18 months of the purchase date of the shares of the fund you exchanged.

How to Exchange Shares

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

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

HOW CAN DIRECT SHAREHOLDERS EXCHANGE SHARES? Direct shareholders can exchange shares of a
Trust for Class A shares of certain eligible funds listed in the SAI. Shares of a
particular class of an eligible fund may be exchanged only for shares of the same class in
other eligible funds. For example, you can exchange shares of the Trust only for Class A
shares of another fund, and you can exchange only Class A shares of another eligible fund
for shares of the Trust. To exchange shares, you must meet several conditions:

o Shares of the fund selected for exchange must be available for sale in your state of
residence.
o The prospectuses of the selected fund must offer the exchange privilege.
o When you establish an account, you must hold the shares you buy for at least seven
days before you can exchange them. After your account is open for seven days, you can
exchange shares on any regular business day, subject to the limitations below.
o You must meet the minimum purchase requirements for the selected fund.
o Generally, exchanges may be made only between identically registered accounts, unless
all account owners send written exchange instructions with a signature guarantee.
o Before exchanging into a fund, you must obtain its prospectus and should read it
carefully.

For tax purposes, an exchange of shares of a Trust is considered a sale of those
shares and a purchase of the shares of the fund to which you are exchanging. An exchange
may result in a capital gain or loss. Since shares of a Trust normally maintain a $1.00
net asset value, in most cases you should not realize a capital gain or loss when you sell
or exchange your shares.

Direct shareholders can find a list of eligible funds currently available for
exchanges in the SAI or you can obtain one by calling a service representative at
1.800.525.9310. The list of eligible funds can change from time to time.

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

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

o Written Exchange Requests. Send an Exchange Authorization Form, signed by all owners
of the account to the Transfer Agent at the address on the back cover. Exchanges of
shares for which share certificates have been issued cannot be processed unless the
Transfer Agent receives the certificates with the request.

o Telephone Exchange Requests. Telephone exchange requests may be made by calling a
service representative at 1.800.525.9310. Telephone exchanges may be made only
between accounts that are registered with the same name(s) and address. Shares for
which share certificates have been issued may not be exchanged by telephone.

Please refer to "How to Exchange Shares" in the SAI for more details.

ARE THERE LIMITATIONS ON FREQUENT PURCHASES, REDEMPTIONS AND EXCHANGES?

Risks from Excessive Purchase, Redemption and Short-Term Exchange Activity. The exchange
privilege affords investors the ability to switch their investments among eligible funds if
their investment needs change. However, there are limits on that privilege. Frequent
purchases, redemptions and exchanges of the Trusts' shares may interfere with the Manager's
ability to manage the Trusts' investments efficiently, increase the Trusts' transaction and
administrative costs and/or affect the Trusts' performance, depending on various factors,
such as the size of the Trusts, the nature of its investments, the amount of the Trusts
assets the portfolio manager maintains in cash or cash equivalents, the aggregate dollar
amount and the number and frequency of trades. If large dollar amounts are involved in
exchange and/or redemption transactions, the Trusts might be required to sell portfolio
securities at unfavorable times to meet redemption or exchange requests, and the Trusts'
brokerage or administrative expenses might be increased.

Therefore, the Manager and the Trusts' Board of Trustees have adopted the following
policies and procedures to detect and prevent frequent and/or excessive exchanges, and/or
purchase and redemption activity, while balancing the needs of investors who seek liquidity
from their investment and the ability to exchange shares as investment needs change. There
is no guarantee that the policies and procedures described below will be sufficient to
identify and deter excessive short-term trading.

o Timing of Exchanges. Exchanged shares are normally redeemed from one fund and the
proceeds are reinvested in the fund selected for exchange on the same regular
business day on which the Transfer Agent or its agent (such as a financial
intermediary holding the investor's shares in an "omnibus" or "street name" account)
receives an exchange request that conforms to these policies. The request must be
received by the close of the NYSE that day, which is normally 4:00 p.m. Eastern time,
but may be earlier on some days, in order to receive that day's net asset value on
the exchanged shares. Exchange requests received after the close of the NYSE will
receive the next net asset value calculated after the request is received. However,
the Transfer Agent may delay the reinvestment of proceeds from an exchange for up to
five business days if it determines, in its discretion, that an earlier transmittal
of the redemption proceeds to the receiving fund would be detrimental to either the
fund from which the exchange is being made or the fund into which the exchange is
being made. The proceeds will be invested in the fund into which the exchange is
being made at the next net asset value calculated after the proceeds are received.
In the event that such delay in the reinvestment of proceeds occurs, the Transfer
Agent will notify you or your financial representative.

o Limits on Disruptive Activity. The Transfer Agent may, in its discretion, limit or
terminate trading activity by any person, group or account that it believes would be
disruptive, even if the activity has not exceeded the policy outlined in this
Prospectus. The Transfer Agent may review and consider the history of frequent
trading activity in all accounts in the Oppenheimer or Centennial funds known to be
under common ownership or control as part of the Transfer Agent's procedures to
detect and deter excessive trading activity.

o Exchanges of Client Accounts by Financial Advisers. The Trusts and the Transfer
Agent permit dealers and financial intermediaries to submit exchange requests on
behalf of their customers (unless the customer has revoked that authority). The
Distributor and/or the Transfer Agent have agreements with a number of financial
intermediaries that permit them to submit exchange orders in bulk on behalf of their
clients. Those intermediaries are required to follow the exchange policies stated in
this Prospectus and to comply with additional, more stringent restrictions. Those
additional restrictions include limitations on the funds available for exchanges, the
requirement to give advance notice of exchanges to the Transfer Agent, and limits on
the amount of client assets that may be invested in a particular fund. A fund or the
Transfer Agent may limit or refuse bulk exchange requests submitted by such financial
intermediaries if, in the Transfer Agent's judgment, exercised in its discretion, the
exchanges would be disruptive to any of the funds involved in the transaction.
o Redemptions of Shares. These exchange policy limits do not apply to redemptions of
shares. Shareholders are permitted to redeem their shares on any regular business
day, subject to the terms of this Prospectus. Further details are provided under "How
to Sell Shares."

o Right to Refuse Exchange and Purchase Orders. The Distributor and/or the Transfer
Agent may refuse any purchase or exchange order in their discretion and are not
obligated to provide notice before rejecting an order. The Trusts may amend, suspend
or terminate the exchange privilege at any time. You will receive 60 days' notice of
any material change in the exchange privilege unless applicable law allows otherwise.

o Right to Terminate or Suspend Account Privileges. The Transfer Agent may send a
written warning to direct shareholders that the Transfer Agent believes may be
engaging in excessive purchases, redemptions and/or exchange activity and reserves
the right to suspend or terminate the ability to purchase shares and/or exchange
privileges for any account that the Transfer Agent determines, in carrying out these
policies and in the exercise of its discretion, has engaged in disruptive or
excessive trading activity, with or without such warning.

o Omnibus Accounts. If you hold your shares of the Trusts through a financial
intermediary such as a broker/dealer, a bank, an insurance company separate account,
an investment adviser, an administrator or trustee of a retirement plan or 529 plan
that holds your shares in an account under its name (these are sometimes referred to
as "omnibus" or "street name" accounts), that financial intermediary may impose its
own restrictions or limitations to discourage short-term or excessive trading. You
should consult your financial intermediary to find out what trading restrictions,
including limitations on exchanges, they may apply.

While the Trusts, the Distributor, the Manager and the Transfer Agent encourage financial
intermediaries to apply the Trusts' policies to their customers who invest indirectly in
the Trusts, the Transfer Agent may not be able to detect excessive short term trading
activity facilitated by, or in accounts maintained in, the "omnibus" or "street name"
accounts of a financial intermediary. Therefore the Transfer Agent might not be able to
apply this policy to accounts such as (a) accounts held in omnibus form in the name of a
broker/dealer or other financial institution, or (b) omnibus accounts held in the name of a
retirement plan or 529 plan trustee or administrator, or (c) accounts held in the name of
an insurance company for its separate account(s), or (d) other accounts having multiple
underlying owners but registered in a manner such that the underlying beneficial owners are
not identified to the Transfer Agent.

However, the Transfer Agent will attempt to monitor overall purchase and redemption
activity in those accounts to seek to identify patterns that may suggest excessive trading
by the underlying owners. If evidence of possible excessive trading activity is observed
by the Transfer Agent, the financial intermediary that is the registered owner will be
asked to review account activity, and to confirm to the Transfer Agent and the Trusts that
appropriate action has been taken to curtail any excessive trading activity. However, the
Transfer Agent's ability to monitor and deter excessive short-term trading in omnibus or
street name accounts ultimately depends on the capability and cooperation of the financial
intermediaries controlling those accounts.

Additional Policies and Procedures. The Trusts' Board has adopted the following additional
policies and procedures to detect and prevent frequent and/or excessive exchanges and
purchase and redemption activity:

o 30-Day Limit. A direct shareholder may exchange all or some of the shares of the
selected Trust held in his or her account to another eligible Oppenheimer fund once
in a 30 calendar-day period. When shares are exchanged into another fund account,
that account will be "blocked" from further exchanges into another fund for a period
of 30 calendar days from the date of the exchange. The block will apply to the full
account balance and not just to the amount exchanged into the account. For example,
if a shareholder exchanged $1,000 from one fund into another fund in which the
shareholder already owned shares worth $10,000, then, following the exchange, the
full account balance ($11,000 in this example) would be blocked from further
exchanges into another fund for a period of 30 calendar days. A "direct shareholder"
is one whose account is registered on a Trust's books showing the name, address and
tax ID number of the beneficial owner.

o Exchanges Into Money Market Funds. A direct shareholder will be permitted to
exchange shares of a stock or bond fund for shares of any money market fund that
offers an exchange privilege at any time, even if the shareholder has exchanged
shares into the stock or bond fund during the prior 30 days. However, all of the
shares held in that money market fund would then be blocked from further exchanges
into another fund for 30 calendar days.

o Dividend Reinvestments. Reinvestment of dividends or distributions from one fund to
purchase shares of another fund will not be considered exchanges for purposes of
imposing the 30-day limit.

o Asset Allocation. Third-party asset allocation and rebalancing programs will be
subject to the 30-day limit described above. Asset allocation firms that want to
exchange shares held in accounts on behalf of their customers must identify
themselves to the Transfer Agent and execute an acknowledgement and agreement to
abide by these policies with respect to their customers' accounts. "On-demand"
exchanges outside the parameters of portfolio rebalancing programs will be subject to
the 30-day limit. However, investment programs by other Oppenheimer "funds-of-funds"
that entail rebalancing of investments in underlying Oppenheimer funds will not be
subject to these limits.

o Automatic Exchange Plans. Accounts that receive exchange proceeds through automatic
or systematic exchange plans that are established through the Transfer Agent will not
be subject to the 30-day block as a result of those automatic or systematic exchanges
(but may be blocked from exchanges, under the 30-day limit, if they receive proceeds
from other exchanges).

Shareholder Account Rules and Policies

More information about the Trusts' policies and procedures for buying, selling and
exchanging shares is contained in the SAI.

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

Telephone transaction privileges for purchases, redemptions or exchanges may be modified,
suspended or terminated by the Trusts at any time. The Trusts will provide you
notice whenever they are required to do so by applicable law. If an account has more
than one owner, the Trusts and the Transfer Agent may rely on the instructions of any
one owner. Telephone privileges apply to each owner of the account and the
broker/dealer representative of record for the account unless the Transfer Agent
receives cancellation instructions from an owner of the account.

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

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

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

The Transfer Agent may delay processing any type of redemption payment as described under
"How to Sell Shares" for recently purchased shares, but only until the purchase
payment has cleared. That delay may be as much as 10 days from the date the shares
were purchased. That delay may be avoided if you purchase shares by Federal Funds
wire or certified check.

Involuntary redemptions of small accounts may be made by the Trusts if the account value
has fallen below $250 for reasons other than the fact that the market value of shares
has dropped. In some cases involuntary redemptions may be made to repay the
Distributor or Sub-Distributor for losses from the cancellation of share purchase
orders.

Federal regulations may require the Trusts to obtain your name, your date of birth (for a
natural person), your residential street address or principal place of business and
your Social Security Number, Employer Identification Number or other government
issued identification when you open an account. Additional information may be
required in certain circumstances or to open corporate accounts. The Trusts or the
Transfer Agent may use this information to attempt to verify your identity. The
Trusts may not be able to establish an account if the necessary information is not
received. The Trusts may also place limits on account transactions while it is in
the process of attempting to verify your identity. Additionally, if the Trusts are
unable to verify your identity after your account is established, the Trusts may be
required to redeem your shares and close your account.

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

To avoid sending duplicate copies of materials to households, the Trusts will mail only one
copy of each prospectus, annual and semi-annual report and annual notice of the
Trusts' privacy policy to shareholders having the same last name and address on the
Trusts' records. The consolidation of these mailings, called householding, benefits
the Trusts through reduced mailing expense.

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

Dividends, Capital Gains and Taxes

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

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

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

o Reinvest All Distributions in the Trust. You can elect to reinvest all dividends and
capital gains distributions in the selected Trust.
o Reinvest Dividends or Capital Gains. You can elect to reinvest some distributions
(dividends, short-term capital gains or long-term capital gains distributions) in the
selected Trust while receiving other types of distributions by check or having them
sent to your bank account.
o Receive All Distributions in Cash. You can elect to receive a check for all
dividends and capital gains distributions or have them sent to your bank.
o Reinvest Your Distributions in Another Account. You can reinvest all distributions
in the same class of shares of another eligible fund account you have established,
provided that the selected fund is available for exchange.

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

TAXES.

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

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

Each Trust intends each year to qualify as a "regulated investment company" under the
Internal Revenue Code, but reserves the right not to qualify. Each Trust qualified during
its last fiscal year. The Trusts, as regulated investment companies, will not be subject
to Federal income taxes on any of its income, provided that it satisfies certain income,
diversification and distribution requirements.

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

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

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

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

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

Financial Highlights

The Financial Highlights Table is presented to help you understand the Trusts' financial
performance for the past five fiscal years. Certain information reflects financial results
for a single Trust share. The total returns in the table represent the rate that an
investor would have earned (or lost) on an investment in the Trusts (assuming reinvestment
of all dividends and distributions). This information has been audited by Deloitte &
Touche LLP, the Trusts' independent registered public accounting firm, whose report, along
with the Trusts' financial statements, are included in the SAI, which is available on
request.

ABOUT THE TRUST
- ------------------------------------------------------------------------------

Additional Information About the Trust's Investment Policies and Risks


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


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

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

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

Ratings of Securities - Portfolio Quality, Maturity and Diversification.
Under Rule 2a-7 of the Investment Company Act of 1940 ("Investment Company
Act"), the Trust uses the amortized cost method to value its portfolio
securities to determine the Trust's net asset value per share.  Rule 2a-7
imposes requirements for the maturity, quality and diversification of the
securities which the Trust buys.  The Trust may purchase only those
securities that the Manager, under procedures approved by the Board of
Trustees, has determined have minimal credit risk and, as such, are "eligible
securities."


|X|   Quality.  Eligible securities are securities that have received a
rating in one of the two highest short-term rating categories by a rating
organization.  Rating organizations are designated by the SEC.  Eligible
securities may be "first tier" or "second tier" securities.  First tier
securities are those that have received a rating in the highest category for
short term debt obligations by at least two rating organizations.  If only
one rating organization has rated the security, it must be rated in the
highest category for that rating organization.  U.S. government securities
and securities issued by a registered money market mutual fund are also first
tier securities.  A second tier security is any eligible security that is not
a first tier security.


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

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

      If a security's rating is downgraded, the Manager or the Board of
Trustees may have to reassess the security's credit risk.  If a security is
downgraded, the Manager or the Board of Trustees will promptly reassess
whether the security continues to present minimal credit risk, reassess the
status of the security as an "eligible security," and take such actions as is
appropriate. If the Trust disposes of the security within five days of the
Manager learning of the downgrade, the Manager will provide the Board of
Trustees with subsequent notice of such downgrade.  If a security is in
default, or ceases to be an eligible security, or is determined no longer to
present minimal credit risks, the Board of Trustees must determine whether it
would be in the best interests of the Trust to dispose of the security.

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


      The Trust may buy a security subject to a demand feature or guarantee.
In this case, with respect to 75% of its total assets, the Trust may not
invest more than 10% of its total assets in securities issued by or subject
to demand features or guarantees issued by the same issuer.  If the security
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.

|X|   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 the maximum permitted maturity under Rule 2a-7 (or
any other applicable rule) which is currently 397 days from the date of
purchase.  The Trust also may buy adjustable and floating rate securities,
enter into repurchase agreements and lend portfolio securities.  Rule 2a-7
defines how the maturities of these securities are determined.

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


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

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

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

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

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

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

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

      Repurchase agreements are considered "loans" under the Investment
Company Act, collateralized by the underlying security.  The Trust's
repurchase agreements require that at all times while the repurchase
agreement is in effect, the collateral's value must equal or exceed the
repurchase price to fully collateralize the repayment obligation.
Additionally, the Manager will monitor the vendor's creditworthiness to
confirm that the vendor is financially sound and will continuously monitor
the collateral's value.  However, if the vendor fails to pay the resale price
on the delivery date, the Trust may incur costs in disposing of the
collateral and may experience losses if there is any delay in its ability to
do so.

      Pursuant to an Exemptive Order issued by the Securities and Exchange
Commission, the Trust, along with other affiliated entities managed by the
Manager, may transfer uninvested cash balances into one or more joint
repurchase accounts. These balances are invested in one or more repurchase
agreements, secured by U.S. government securities. Securities that are
pledged as collateral for repurchase agreements are held by a custodian bank
until the agreements mature. Each joint repurchase arrangement requires that
the market value of the collateral be sufficient to cover payments of
interest and principal; however, in the event of default by the other party
to the agreement, retention or sale of the collateral may be subject to legal
proceedings.

Other Investment Strategies

|X|   Floating Rate/Variable Rate Obligations.  The Trust may invest in
instruments with floating or variable interest rates.  The interest rate on a
floating rate obligation is based on a stated prevailing market rate, such as
a bank's prime rate, the 90-day U.S. Treasury Bill rate, the rate of return
on commercial paper or bank certificates of deposit, or some other standard.
The rate on the investment is adjusted automatically each time the market
rate is adjusted.  The interest rate on a variable rate obligation is also
based on a stated prevailing market rate but is adjusted automatically at a
specified interval.  Some variable rate or floating rate obligations in which
the Trust may invest have a demand feature entitling the holder to demand
payment of an amount approximately equal to the amortized cost of the
instrument or the principal amount of the instrument plus accrued interest at
any time, or at specified intervals not exceeding the maximum time permitted
under Rule 2a-7 (which is currently 397 days).  These notes may or may not be
backed by bank letters of credit.

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


      Because these types of obligations are direct lending arrangements
between the note purchaser and issuer of the note, these instruments
generally will not be traded.  Generally, there is no established secondary
market for these types of obligations, although they are redeemable from the
issuer at face value.  Accordingly, where these obligations are not secured
by letters of credit or other credit support arrangements, the Trust's right
to redeem them is dependent on the ability of the note issuer to pay
principal and interest on demand.  These types of obligations usually are not
rated by credit rating agencies.  The Trust may invest in obligations that
are not rated only if the Manager determines at the time of investment that
they are eligible securities.  The Manager, on behalf of the Trust, will
monitor the creditworthiness of the issuers of the floating and variable rate
obligations in the Trust's portfolio on an ongoing basis.  There is no limit
on the amount of the Trust's assets that may be invested in floating rate and
variable rate obligations that meet the requirements of Rule 2a-7.

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

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

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


|X|   Loans of Portfolio Securities.  To attempt to increase its income, the
Trust may lend its portfolio securities to brokers, dealers and other
financial institutions.  These loans are limited to not more than 25% of the
value of the Trust's total assets and are subject to other conditions
described below. The Trust will not enter into any securities lending
agreements having a maturity of greater than the maximum time permitted under
Rule 2a-7. The Trust presently does not intend to lend its portfolio
securities, but if it does the value of securities loaned will not exceed 5%
of the value of the Trust's total assets in the coming year. There are some
risks in lending securities.  The Trust could experience a delay in receiving
additional collateral to secure a loan, or a delay in recovering the loaned
securities.

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

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

      The Trust will not lend its portfolio securities to any officer,
Trustee, employee or affiliate of the Trust or its Manager.  The terms of the
Trust's loans must meet certain tests under the Internal Revenue Code and
permit the Trust to reacquire loaned securities on five business days notice
or in time to vote on any important matter.

|X|   Bank Loan Participation Agreements.  The Fund may invest in bank loan
participation agreements, subject to the investment limitation set forth in
the Prospectus as to investments in illiquid securities.  Participation
agreements provide an undivided interest in a loan made by the bank issuing
the participation interest in the proportion that the buyer's investment
bears to the total principal amount of the loan.  Under this type of
arrangement, the issuing bank may have no obligation to the buyer other than
to pay principal and interest on the loan if and when received by the bank.
Thus, the Trust must look to the creditworthiness of the borrower, which is
obligated to make payments of principal and interest on the loan.  If the
borrower fails to pay scheduled principal or interest payments, the Trust may
experience a reduction in income.

Other Investment Restrictions

      |X|   What Are "Fundamental Policies?" Fundamental policies are those
policies that the Trust has adopted to govern its investments that can be
changed only by the vote of a "majority" of the Trust's outstanding voting
securities.  Under the Investment Company Act, a "majority" vote is defined
as the vote of the holders of the lesser of:
o     67% or more of the shares present or represented by proxy at a
            shareholder meeting, if the holders of more than 50% of the
            outstanding shares are present or represented by proxy, or
o     more than 50% of the outstanding shares.

      The Trust's investment objective is a fundamental policy. Other
policies described in the Prospectus or this Statement of Additional
Information are "fundamental" only if they are identified as such.  The
Trust's Board of Trustees can change non-fundamental policies without
shareholder approval.  However, significant changes to investment policies
will be described in supplements or updates to the Prospectus or this
Statement of Additional Information, as appropriate. The Trust's most
significant investment policies are described in the Prospectus.

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

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

o     The Trust cannot borrow money in excess of 10% of the value of its
            total assets, and then only as a temporary measure for
            extraordinary or emergency purposes; provided that the Trust will
            not make any investment at a time during which such borrowing
            exceeds 5% of the value of its assets; no assets of the Trust may
            be pledged, mortgaged or assigned to secure a debt.

o     The Trust cannot make loans, except through (i) the purchase of debt
            securities listed in the Prospectus under "Investment Objective
            and Policies," (ii) the purchase of such debt securities subject
            to repurchase agreements, or (iii) loans of securities as
            described under "Other Investment Strategies - Loans of Portfolio
            Securities," in this Statement of Additional Information.

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

o     The Trust cannot invest in real estate.

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

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

o     The Trust cannot underwrite securities of other companies.

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

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

o     The Trust cannot invest in any debt instrument having a remaining
            maturity in excess of the maturity limitation in Rule 2a-7 of the
            Investment Company Act, as it may be amended from time to time,
            or any other applicable rule, unless it is a debt instrument that
            is (1) subject to a repurchase agreement, (2) called for
            redemption, or (3) purchased subject to a demand feature such
            that the security is due and payable within the remaining
            maturity limitation in Rule 2a-7.

o     The Trust cannot concentrate investment in any particular industry.
            Therefore the Trust will not purchase the securities of issuers
            in any one industry if as a result of that purchase 25% or more
            of the value of the Trust's total assets would consist of
            securities of issuers in that industry.  The Trust's investments
            in U.S. government securities and bank obligations located in the
            United States (other than obligations of foreign branches of
            domestic banks and obligations issued or guaranteed by foreign
            banks) are not subject to this limitation.


Disclosure of Portfolio Holdings.  The Trust has adopted policies and
procedures concerning the dissemination of information about its portfolio
holdings by employees, officers and/or trustees of the Manager, Distributor,
Sub-Distributor and Transfer Agent.  These policies are designed to assure
that non-public information about portfolio securities is distributed only
for a legitimate business purpose, and is done in a manner that (a) conforms
to applicable laws and regulations and (b) is designed to prevent that
information from being used in a way that could negatively affect the Trust's
investment program or enable third parties to use that information in a
manner that is harmful to the Trust.

o     Public Disclosure. The Trust's portfolio holdings are made publicly
      available no later than 60 days after the close of each of the Trust's
      fiscal quarters in semi-annual and annual reports to shareholders, or
      in its Statements of Investments on Form N-Q, which are publicly
      available at the Securities and Exchange Commission (the "SEC").

Until publicly disclosed the Trust's portfolio holdings are proprietary,
confidential business information.  While recognizing the importance of
providing the Trust's shareholders with information about their Trust's
investments and providing portfolio information to a variety of third parties
to assist with the management, distribution and administrative process, the
need for transparency must be balanced against the risk that third parties
who gain access to the Trust's portfolio holdings information could attempt
to use that information to trade ahead of or against the Trust, which could
negatively affect the prices the Trust is able to obtain in portfolio
transactions or the availability of the securities that portfolio managers
are trading on the Trust's behalf.


The Manager and its subsidiaries and affiliates, employees, officers, and
directors, shall neither solicit, nor accept any compensation or other
consideration (including any agreement to maintain assets in the Trust or in
other investment companies or accounts managed by the Manager or any
affiliated person of the Manager) in connection with the disclosure the
Trust's non-public portfolio holdings.  The receipt of investment advisory
fees or other fees and compensation paid to the Manager and its subsidiaries
pursuant to agreements approved by the Trust's Board shall not be deemed to
be "compensation" or "consideration" for these purposes.  It is a violation
of the Code of Ethics for any covered person to release holdings in
contravention of portfolio holdings disclosure policies and procedures
adopted by the Trust.


A list of the top 10 or more portfolio securities holdings (based on invested
assets), listed by security or by issuer, as of the end of each month may be
disclosed to third parties (subject to the procedures below) no sooner than
15 days after month-end.

      Except under special limited circumstances discussed below, month-end
lists of the Trust's complete portfolio holdings may be disclosed no sooner
than 30-days after the relevant month-end, subject to the procedures below.
If the Trust's complete portfolio holdings have not been disclosed publicly,
they may be disclosed pursuant to special requests for legitimate business
reasons, provided that:

o     The third-party recipient must first submit a request for release of
            Trust portfolio holdings, explaining the business reason for the
            request;
o     Senior officers (a Senior Vice President or above) in the Manager's
            Portfolio and Legal departments must approve the completed
            request for release of Trust portfolio holdings; and
o     The third-party recipient must sign the Manager's portfolio holdings
            non-disclosure agreement before receiving the data, agreeing to
            keep information that is not publicly available regarding the
            Trust's holdings confidential and agreeing not to trade directly
            or indirectly based on the information.


    The Trust's complete portfolio holdings positions may be released to the
    following categories of entities or individuals on an ongoing basis,
    provided that such entity or individual either (1) has signed an
    agreement to keep such information confidential and not trade on the
    basis of such information or (2) is subject to fiduciary obligations, as
    a member of the Trust's Board, or as an employee, officer and/or director
    of the Manager, Distributor, Sub-Distributor or Transfer Agent, or their
    respective legal counsel, not to disclose such information except in
    conformity with these policies and procedures and not to trade for
    his/her personal account on the basis of such information:

o     Employees of the Trust's Manager, Sub-Distributor, Distributor and
            Transfer Agent who need to have access to such information (as
            determined by senior officers of such entity),
o     The Trust's independent registered public accounting firm,
o     Members of the Trust's Board and the Board's legal counsel,
o     The Trust's custodian bank,
o     A proxy voting service designated by the Trust and its Board,
o     Rating/ranking organizations (such as Lipper and Morningstar),
o     Portfolio pricing services retained by the Manager to provide portfolio
            security prices, and
o     Dealers, to obtain bids (price quotations if securities are not priced
            by the Trust's regular pricing services).



      Portfolio holdings information of the Trust may be provided, under
    limited circumstances, to brokers and/or dealers with whom the Trust
    trades and/or entities that provide investment coverage and/or analytical
    information regarding the Trust's portfolio, provided that there is a
    legitimate investment reason for providing the information to the broker,
    dealer or other entity. Month-end portfolio holdings information may,
    under this procedure, be provided to vendors providing research
    information and/or analytics to the fund, with at least a 15-day delay
    after the month end, but in certain cases may be provided to a broker or
    analytical vendor with a 1-2 day lag to facilitate the provision of
    requested investment information to the Manager to facilitate a
    particular trade or the portfolio manager's investment process for the
    Trust. Any third party receiving such information must first sign the
    Manager's portfolio holdings non-disclosure agreement as a pre-condition
    to receiving this information.


      Portfolio holdings information (which may include information on
    individual securities positions or multiple securities) may be provided
    to the entities listed below (1) by portfolio traders employed by the
    Manager in connection with portfolio trading, and (2) by the members of
    the Manager's Security Valuation Group and Accounting Departments in
    connection with portfolio pricing or other portfolio evaluation purposes:
o     Brokers and dealers in connection with portfolio transactions
            (purchases and sales)

o     Brokers and dealers to obtain bids or bid and asked prices (if
            securities held by  the Trust are not priced by the Trust's
            regular pricing services)
o     Dealers to obtain price quotations where the Trust is not identified as
            the owner


      Portfolio holdings information (which may include information on the
    Trust's entire portfolio or individual securities therein) may be
    provided by senior officers of the Manager or attorneys on the legal
    staff of the Manager, Distributor, or Transfer Agent, in the following
    circumstances:

o     Response to legal process in litigation matters, such as responses to
            subpoenas or in class action matters where the Trust may be part
            of the plaintiff class (and seeks recovery for losses on a
            security) or a defendant,
o     Response to regulatory requests for information (the SEC, NASD, state
            securities regulators, and/or foreign securities authorities,
            including without limitation requests for information in
            inspections or for position reporting purposes),
o     To potential sub-advisers of portfolios (pursuant to confidentiality
            agreements),
o     To consultants for retirement plans for plan sponsors/discussions at
            due diligence meetings (pursuant to confidentiality agreements),
o     Investment bankers in connection with merger discussions (pursuant to
            confidentiality agreements)

      Portfolio managers and analysts may, subject to the Manager's policies
on communications with the press and other media, discuss portfolio
information in interviews with members of the media, or in due diligence or
similar meetings with clients or prospective purchasers of Trust shares or
their financial intermediary representatives.

      The Trust's shareholders may, under unusual circumstances (such as a
lack of liquidity in the Trust's portfolio to meet redemptions), receive
redemption proceeds of their Trust shares paid as pro rata shares of
securities held in the Trust's portfolio. In such circumstances, disclosure
of the Trust's portfolio holdings may be made to such shareholders.

      The Chief Compliance Officer of the Trust and the Manager,
Sub-Distributor, Distributor, and Transfer Agent (the "CCO") shall oversee
the compliance by the Manager, Sub-Distributor, Distributor, Transfer Agent,
and their personnel with these policies and procedures. At least annually,
the CCO shall report to the Trust's Board on such compliance oversight and on
the categories of entities and individuals to which disclosure of portfolio
holdings of the Trust has been made during the preceding year pursuant to
these policies. The CCO shall report to the Trust's Board any material
violation of these policies and procedures during the previous calendar
quarter and shall make recommendations to the Boards as to any amendments
that the CCO believes are necessary and desirable to carry out or improve
these policies and procedure.

The Manager and/or the Trust have entered into ongoing arrangements to make
available information about the Trust's portfolio holdings. One or more of
the Oppenheimer funds may currently disclose portfolio holdings information
based on ongoing arrangements to the following parties:

How the Trust is Managed

Organization and History.  The Trust is an open-end, diversified management
investment company organized as a Massachusetts business trust in 1981, with
an unlimited number of authorized shares of beneficial interest.

|X|   Classes  of  Shares.  The Trust  has a single  class of shares of stock.
While  that class has no  designation,  it is deemed to be the  equivalent  of
Class A for purposes of the shareholder  account  policies that apply to Class
A shares of the Oppenheimer funds.

      Shares of the Trust are freely transferable.  Each share has one vote
at shareholder meetings, with fractional shares voting proportionally on
matters submitted to a vote of shareholders.  There are no preemptive or
conversion rights and shares participate equally in the assets of the Trust
upon liquidation.


|X|   Meetings of Shareholders.  As a Massachusetts  business trust, the Trust
is not required to hold, and does not plan to hold,  regular  annual  meetings
of shareholders,  but may hold meetings from time to time on important matters
or when required to do so by the  Investment  Company Act or other  applicable
law.  Shareholders  have the right,  upon a vote or  declaration in writing of
two-thirds  of the  outstanding  shares of the Trust to remove a Trustee or to
take other action described in the Trust's Declaration of Trust.


      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.  If the Trustees receive a request from at least 10
shareholders stating that they wish to communicate with other shareholders to
request a meeting to remove a Trustee, the Trustees will then either make the
Trust's shareholder list available to the applicants or mail their
communication to all other shareholders at the applicants' expense. The
shareholders making the request must have been shareholders for at least six
months and must hold shares of the Trust valued at $25,000 or more or
constituting at least 1% of the Trust's outstanding shares, whichever is
less. The Trustees may also take other action as permitted by the Investment
Company Act.


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









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


Board of Trustees and Oversight Committees. The Trust is governed by a Board
of Trustees, which is responsible for protecting the interests of
shareholders under Massachusetts law. The Trustees meet periodically
throughout the year to oversee the Trust's activities, review its
performance, and review the actions of the Manager.


      The Board of Trustees has an Audit Committee, a Review Committee and a
Governance Committee. The Audit Committee and Governance Committee are
comprised solely of Trustees who are not "interested persons" under the
Investment Company Act (the "Independent Trustees"). The members of the Audit
Committee are Edward L. Cameron (Chairman), George C. Bowen, Robert J. Malone
and F. William Marshall, Jr. The Audit Committee held 8 meetings during the
Trust's fiscal year ended June 30, 2006. The Audit Committee furnishes the
Board with recommendations regarding the selection of the Fund's independent
registered public accounting firm (also referred to as the "independent
Auditors"). Other main functions of the Audit Committee, outlined in the
Audit Committee Charter, include, but are not limited to: (i) reviewing the
scope and results of financial statement audits and the audit fees charged;
(ii) reviewing reports from the Trust's independent Auditors regarding the

Governance Committee held 5 meetings during the Trust's fiscal year ended
June 30, 2006.  The Governance Committee has adopted a charter setting forth
its duties and responsibilities. Among other duties, the Governance Committee
reviews and oversees the Trust's governance guidelines, the adequacy of the
Trust's Codes of Ethics and the nomination of Trustees, including Independent
Trustees. The Governance Committee has adopted a process for shareholder
submission of nominees for board positions. Shareholders may submit names of
individuals, accompanied by complete and properly supported resumes, for the
Governance Committee's consideration by mailing such information to the
Governance Committee in care of the Trust. The Governance Committee may
consider such persons at such time as it meets to consider possible nominees.
The Governance Committee, however, reserves sole discretion to determine
which candidates for Trustees and Independent Trustees it will recommend to
the Board and/or shareholders and it may identify candidates other than those
submitted by Shareholders. The Governance Committee may, but need not,
consider the advice and recommendation of the Manager and/or its affiliates
in selecting nominees. The full Board elects new Trustees except for those
instances when a shareholder vote is required.

      Shareholders who desire to communicate with the Board should address
correspondence to the Board or an individual Board member and may submit
their correspondence electronically at www.oppenheimerfunds.com under the

      Present or former officers, directors, trustees and employees (and
their immediate family members) of the Trust, the Manager and its affiliates,
and retirement plans established by them for their employees are permitted to
purchase Class A shares of the Trust and the other Oppenheimer funds at net
asset value without sales charge. The sales charge on Class A shares is
waived for that group because of the reduced sales efforts realized by the
Distributor.

and Zack and Mss. Wolf, Bloomberg, and Ives who are officers of the Trust,
hold the same offices with one or more of the other Board II Funds. As of

beneficially owned under that plan by the officers of the Board II Funds. In
addition, none of the Independent Trustees (nor any of their immediate family
members) owns securities of either the Manager, Distributor or the
Sub-Distributor, or of any entity directly or indirectly controlling,

1.    "Aggregate Compensation From the Trust" includes fees and deferred
   compensation, if any.
2.    In accordance with SEC regulations, for purposes of this section only,
   "Fund Complex" includes the Oppenheimer funds, the MassMutual
   Institutional Funds, the Massmutual Select Funds and the MML Series
   Investment Fund, the investment adviser for which is the indirect parent
   company of OppenheimerFunds, Inc. OppenheimerFunds, Inc. also serves as
   the Sub-Advisor to the following: MassMutual Premier International Equity
   Fund, MassMutual Premier Main Street Fund, MassMutual Premier Strategic
   Income Fund, MassMutual Premier Capital Appreciation Fund, and MassMutual
   Premier Global Fund. OppenheimerFunds, Inc. does not consider MassMutual
   Institutional Funds, MassMutual Select Funds and MML Series Investment
   Fund to be part of the OppenheimerFunds' "Fund Complex" as that term may
   be otherwise interpreted.

3.    Mr. Grabish serves as a Trustee for only  the following funds:
   Centennial California Tax Exempt Trust, Centennial Government Trust,
   Centennial Money Market Trust, Centennial New York Tax Exempt Trust and
   Centennial Tax Exempt Trust.

4.    Includes $945 deferred by Ms. Hamilton under the "Deferred Compensation

5. Includes $547 deferred by Mr. Malone under the "Deferred Compensation
   Plan" described below.
6.    Includes $51,000 compensation paid to Mr. Marshall for serving as a
   Trustee for MassMutual Select Funds and MML Series Investment Fund.


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


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

      |X|               Major Shareholders.  As of August 14, 2006 the only
person who owned of record or was known by the Trust to own beneficially 5%
or more of the Trust's outstanding shares was A.G. Edwards & Sons,
Inc.("Edwards"), for the Sole Benefit of its Customers, Attn. Money Fund
Dept., 1 North Jefferson Avenue, St. Louis, Missouri 63103, which owned
1,122,946,412.380 shares of the Trust which was 94.35% of the outstanding
shares of the Trust on that date, for accounts of its customers none of whom
individually owned more than 5% of the outstanding shares.  A.G. Edwards,
Inc. is a minority owner of Oppenheimer Acquisition Corporation, the parent
company of the Manager, Distributor, and the Transfer Agent.


The Manager.  The Manager, Centennial Asset Management Corporation, is
wholly-owned by OppenheimerFunds, Inc., which is a wholly-owned subsidiary of
Oppenheimer Acquisition Corp., a holding company controlled by Massachusetts
Mutual Life Insurance Company, a global, diversified insurance and financial
services organization.

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


|X|   Code of Ethics.  The Manager and the Distributor have a Code of
Ethics.  It is designed to detect and prevent improper personal trading by
certain employees, including portfolio managers, have access to information
that could permit them to compete with or take advantage of the Trust's
portfolio transactions.  Covered persons include persons with knowledge of
the investments and investment intentions of the Trust and other funds
advised by the Manager.  The Code of Ethics does permit personnel subject to
the Code to invest in securities, including securities that may be purchased
or held by the Trust, subject to a number of restrictions and controls.
Compliance with the Code of Ethics is carefully monitored and enforced by the
Manager.  The Trust does not have a Code of Ethics since it is a money market
fund.


      |X|               The Investment Advisory Agreement.  The Manager
provides investment advisory and management services to the Trust under an
investment advisory agreement between the Manager and the Trust.  The Manager
selects securities for the Trust's portfolio and handles its day-to-day
business.  The agreement requires the Manager, at its expense, to provide the
Trust with adequate office space, facilities and equipment.  It also requires
the Manager to provide and supervise the activities of all administrative and
clerical personnel required to provide effective administration for the
Trust.  Those responsibilities include the compilation and maintenance of
records with respect to its operations, the preparation and filing of
specified reports, and composition of proxy materials and registration
statements for continuous public sale of shares of the Trust.


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


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

      2004                                 $7,022,839

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

      2005                                 $6,029,326

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

      2006                                 $5,392,083

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


      Prior to the Shareholder vote held on September 19, 2003, when this
limitation was removed, the investment advisory agreement required the
Manager to reimburse the Trust to the extent that the Trust's total expenses
(including the management fee but excluding interest, taxes, brokerage
commissions, and extraordinary expenses such as litigation costs) exceed in
any fiscal year the lesser of: (i) 1.5% of average annual net assets of the
Trust up to $30 million plus 1% of the average annual net assets in excess of
$30 million or; (ii) 25% of the total annual investment income of the Trust.
For the 2004 fiscal year the Manager reimbursed $1,698,577 to the Trust.


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

 Portfolio Managers. The Trust's portfolio is managed by Barry D. Weiss and
Carol E. Wolf (each is referred to as a "Portfolio Manager" and collectively
they are referred to as the "Portfolio Managers"). They are the persons who
are responsible for the day-to-day management of the Trust's investments.


      Other Accounts Managed.  In addition to managing the Trust's investment
portfolio, each Portfolio Manager also manages other investment portfolios
and other accounts on behalf of the Manager or its affiliates.  The following
table provides information regarding the other portfolios and accounts
managed by each Portfolio Manager as of June 30, 2006. No account has a
performance-based advisory fee:

     -----------------
        *  In millions.

       (1) Does not include personal account of portfolio managers and their
       families, which are subject to the Code of   Ethics.

     As indicated above, the Portfolio Managers also manage other funds and
     accounts.  Potentially, at times, those responsibilities could conflict
     with the interests of the Trust.  That may occur whether the investment
     strategies of the other fund or account are the same as, or different
     from, the Trust's investment objectives and strategies.  For example,
     the Portfolio Managers may need to allocate investment opportunities
     between the Trust and another fund or account having similar objectives
     or strategies, or he may need to execute transactions for another fund
     or account that could have a negative impact on the value of securities
     held by the Trust.  Not all funds and accounts advised by the Manager
     have the same management fee.  If the management fee structure of
     another fund or account is more advantageous to the Manager than the fee
     structure of the Trust, the Manager could have an incentive to favor the
     other fund or account.  However, the Manager's compliance procedures and
     Code of Ethics recognize the Manager's fiduciary obligations to treat
     all of its clients, including the Trust, fairly and equitably, and are
     designed to preclude the Portfolio Manager from favoring one client over
     another. It is possible, of course, that those compliance procedures and
     the Code of Ethics may not always be adequate to do so.  At different
     times, the Trust's Portfolio Managers may manage other funds or accounts
     with investment objectives and strategies that are similar to those of
     the Trust, or may manage funds or accounts with investment objectives
     and strategies that are different from those of the Fund.

      Compensation of the Portfolio Managers.  The Trust's Portfolio Managers
      are employed and compensated by the Manager, not the Trust. Under the
      Manager's compensation program for its portfolio managers and portfolio
      analysts, their compensation is based primarily on the investment
      performance results of the funds and accounts they manage, rather than
      on the financial success of the Manager. This is intended to align the
      portfolio managers' and analysts' interests with the success of the
      funds and accounts and their shareholders. The Manager's compensation
      structure is designed to attract and retain highly qualified investment
      management professionals and to reward individual and team
      contributions toward creating shareholder value. As of June 30, 2006
      the Portfolio Managers' compensation consisted of three elements: a
      base salary, an annual discretionary bonus and eligibility to
      participate in long-term awards of options and appreciation rights in
      regard to the common stock of the Manager's holding company parent.
      Senior portfolio managers may also be eligible to participate in the
      Manager's deferred compensation plan.


      To help the Manager attract and retain talent, the base pay component
      of each portfolio manager is reviewed regularly to ensure that it
      reflects the performance of the individual, is commensurate with the
      requirements of the particular portfolio, reflects any specific
      competence or specialty of the individual manager, and is competitive
      with other comparable positions. The annual discretionary bonus is
      determined by senior management of the Manager and is based on a number
      of factors, including a fund's pre-tax performance for periods of up to
      five years, measured against an appropriate Lipper benchmark selected
      by management. The Lipper benchmark with respect to the Trust is Lipper
      - U.S. Government Money Market Funds. Other factors considered include
      management quality (such as style consistency, risk management, sector
      coverage, team leadership and coaching) and organizational development.
      The Portfolio Managers' compensation is not based on the total value of
      the Trust's portfolio assets, although the Trust's investment
      performance may increase those assets. The compensation structure is
      also intended to be internally equitable and serve to reduce potential
      conflicts of interest between the Trust and other funds and accounts
      managed by the Portfolio Managers. The compensation structure of the
      other funds and accounts managed by the Portfolio Managers is the same
      as the compensation structure of the Trust, described above.

     Ownership of Trust Shares.  As of June 30, 2006 the Portfolio  Managers did
not beneficially own any shares of the Trust.



|X| The Distributor.  Under its General Distributor's  Agreement with the Trust,
Centennial   Asset  Management   Corporation  acts  as  the  Trust's   principal
underwriter  and  Distributor in the continuous  public  offering of the Trust's
shares.  The  Distributor is not obligated to sell a specific  number of shares.
The Distributor  bears the expenses  normally  attributable to sales,  including
advertising and the cost of printing and mailing prospectuses,  other than those
furnished to existing shareholders.  For other distribution expenses paid by the
Trust,   see  the  section   entitled   "Service   Plan"   below.   The  Trust's
Sub-Distributor is OppenheimerFunds Distributor, Inc.


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

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

     The research  services provided by brokers broaden the scope and supplement
the research activities of the Manager.  That research provides additional views
and  comparisons  for  consideration,   and  helps  the  Manager  obtain  market
information  for the  valuation of securities  held in the Trust's  portfolio or
being considered for purchase. No portfolio  transactions will be handled by any
securities dealer affiliated with the Manager.

     The Trust may  experience  high  portfolio  turnover  that may increase the
Trust's transaction costs.  However,  since brokerage  commissions,  if any, are
small, high turnover does not have an appreciable adverse effect upon the income
of the Trust.

            Service Plan

The Trust has adopted a Service Plan for the shares.  The plan has been approved
by a vote of the Board of  Trustees,  including  a majority  of the  Independent
Trustees(1),  cast in person at a meeting  called  for the  purpose of voting on
that plan.

     Under the plan,  the  Manager  and the  Distributor  may make  payments  to
affiliates.  In their  sole  discretion,  they may also  from  time to time make
substantial  payments  from their own  resources,  which include the profits the
Manager derives from the advisory fees it receives from the Trust, to compensate
brokers, dealers,  financial institutions and other intermediaries for providing
distribution assistance and/or administrative services or that otherwise promote
sales of the Trust's shares. These payments, some of which may be referred to as
"revenue   sharing,"  may  relate  to  the  Fund's   inclusion  on  a  financial
intermediary's preferred list of funds offered to its clients.

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

     The  Board of  Trustees  and the  Independent  Trustees  must  approve  all
material  amendments to the plan. An amendment to increase materially the amount
of payments to be made under the plan must be  approved by  shareholders  of the
class  affected  by the  amendment.  The  approval  must be by a majority of the
shares.

     While the plan is in  effect,  the  Treasurer  of the Trust  shall  provide
separate written reports on the plan to the Board of Trustees at least quarterly
for its review.  The reports  shall detail the amount of all payments made under
the plan and the purpose for which the  payments  were made.  Those  reports are
subject to the review and approval of the Independent Trustees.

     The plan states that while it is in effect, the selection and nomination of
those  Trustees  of the Trust who are not  "interested  persons" of the Trust is
committed to the discretion of the Independent  Trustees.  This does not prevent
the involvement of others in the selection and nomination process as long as the
final  decision as to selection or  nomination  is approved by a majority of the
Independent Trustees.


     Under the plan,  no payment will be made to any  recipient in any period in
which the  aggregate  net asset value of all Trust shares held by the  recipient
for itself and its customers does not exceed a minimum amount,  if any, that may
be set from time to time by a majority of the Independent Trustees. The Board of
Trustees has set no minimum  amount of assets to qualify for payments  under the
plan.

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

     For the fiscal year ended June 30,  2006  payments  under the plan  totaled
$2,381,973,  all of  which  was  paid  by the  Distributor  to  recipients.  The
Distributor  retained  nothing  and the  remaining  balance  was paid out by the
Distributor to recipients,  which included  $179,206 paid to an affiliate of the
Distributor's parent company.  Any unreimbursed  expenses the Distributor incurs
with  respect  to the  shares  in any  fiscal  quarter  cannot be  recovered  in
subsequent  quarters.  The Distributor  may not use payments  received under the
plan to pay any of its interest expenses,  carrying charges,  or other financial
costs, or allocation of overhead.

For the fiscal year ended June 30, 2006,  the Manager  paid,  in the  aggregate,
$2,547,982 in fees out of its own resources for distribution  assistance to A.G.
Edwards & Sons, Inc. Those distribution  assistance payments were paid based
on annual  rates  applied to the  average net asset  value  during the  calendar
quarter of qualified assets of the Centennial funds.

Payments to Trust Intermediaries

     Financial  intermediaries  may receive  various  forms of  compensation  or
reimbursement  from the Trust in the form of 12b-1 plan payments as described in
the preceding section of this SAI.  Additionally,  the Manager,  the Distributor
and/or the  Sub-Distributor  (including  their  affiliates) may make payments to
financial intermediaries in connection with their offering and selling shares of
the Trust and other  Oppenheimer  or Centennial  funds,  providing  marketing or
promotional  support,  transaction  processing and/or  administrative  services.
Among the financial  intermediaries  that may receive these payments are brokers
and dealers who sell and/or  hold  shares of the Trust,  banks  (including  bank
trust  departments),   registered  investment  advisers,   insurance  companies,
retirement  plan and  qualified  tuition  program  administrators,  third  party
administrators,  and other institutions that have selling,  servicing or similar
arrangements with the Manager,  Distributor or Sub-Distributor.  The payments to
intermediaries  vary by the types of product sold, the features of the Trust and
the role played by the intermediary.

     Possible  types of payments to financial  intermediaries  include,  without
limitation, those discussed below.

o    Payments made by the Trust,  or by an investor  buying or selling shares of
     the Trust may include:

o    ongoing  asset-based  payments  attributable  to the share class  selected,
     including  fees payable  under the Trust's  service plan adopted under Rule
     12b-1 under the  Investment  Company  Act,  which are paid from the Trust's
     assets (see " Service Plan" above);

o    shareholder   servicing   payments  for   providing   omnibus   accounting,
     recordkeeping,  networking,  sub-transfer agency or other administrative or
     shareholder services, including retirement plan and 529 plan administrative
     services fees,  which are paid from the assets of a Trust as  reimbursement
     to the Manager,  Distributor or Sub-Distributor  for expenses they incur on
     behalf of the Trust.

o    Payments made by the Manager,  Distributor or Sub-Distirbutor  out of their
     respective  resources  and assets,  which may  include  profits the Manager
     derives from investment advisory fees paid by the Trust. These payments are
     made  at  the  discretion  of  the  Manager,  the  Distributor  and/or  the
     Sub-Distributor.  These  payments,  often referred to as "revenue  sharing"
     payments, may be in addition to the payments by the Trust listed above.

o    These types of payments may reflect  compensation  for  marketing  support,
     support  provided in offering the Trust or other  Oppenheimer or Centennial
     funds  through   certain  trading   platforms  and  programs,   transaction
     processing or other services;

o    The  Manager,  Distributor  and  Sub-Distributor  each may  also pay  other
     compensation  to the extent the payment is not  prohibited by law or by any
     self-regulatory  agency,  such as the NASD.  Payments are made based on the
     guidelines  established by the Manager,  Distributor  and  Sub-Distributor,
     subject to applicable law.

     These  payments may provide an incentive  to  financial  intermediaries  to
actively market or promote the sale of shares of the Trust or other  Oppenheimer
or Centennial  funds, or to support the marketing or promotional  efforts of the
Distributor  or  Sub-Distributor  in  offering  shares  of the  Trust  or  other
Oppenheimer or Centennial funds. In addition, some types of payments may provide
a financial  intermediary  with an incentive to recommend  the Trust.  Financial
intermediaries  may earn  profits  on these  payments,  since the  amount of the
payment may exceed the cost of providing the service.  Certain of these payments
are subject to limitations under applicable law.  Financial  intermediaries  may
categorize  and disclose these  arrangements  to their clients and to members of
the public in a manner different from the disclosures in the Trust's  prospectus
and this SAI. You should ask your financial  intermediary for information  about
any payments it receives from the Trust,  the Manager,  the  Distributor  or the
Sub-Distributor  and  any  services  it  provides,  as  well  as  the  fees  and
commissions it charges.

     Although brokers or dealers that sell Trust shares may also act as a broker
or dealer in connection  with the execution of the purchase or sale of portfolio
securities by the Trust or other  Oppenheimer  or Centennial  funds, a financial
intermediary's  sales of  shares  of the  Trust  or such  other  Oppenheimer  or
Centennial funds is not a consideration for the Manager when choosing brokers or
dealers to effect portfolio transactions for the Trust or such funds.

     Revenue  sharing  payments  can  pay  for   distribution-related  or  asset
retention items including, without limitation,

     o    transactional support,  one-time charges for setting up access for the
          Trust or other Oppenheimer and Centennial funds on particular  trading
          systems, and paying the intermediary's networking fees;

     o    program support, such as expenses related to including the Oppenheimer
          and  Centennial  funds in retirement  plans,  college  savings  plans,
          fee-based advisory or wrap fee programs, fund "supermarkets",  bank or
          trust company  products or insurance  companies'  variable  annuity or
          variable life insurance products;

     o    placement  on  the  dealer's  list  of  offered  funds  and  providing
          representatives   of  the  Distributor  with  access  to  a  financial
          intermediary's

            ------------------------------=======================================

sales   meetings,    ADVEST,   INC.   sales   representatives   and   management
representatives.

     Additionally, the Manager, Distributor or Sub-Distributor may make payments
for  firm  support,  such as  business  planning  assistance,  advertising,  and
educating a financial  intermediary's  sales personnel about the Oppenheimer and
Centennial funds and shareholder financial planning needs.

     For  the  year  ended   December  31,   2005,   the   following   financial
intermediaries  that are  broker-dealers  offering shares of the Oppenheimer and
Centennial funds, and/or their respective  affiliates,  received revenue sharing
or  similar  distribution-related  payments  from the  Manager,  Distributor  or
Sub-Dsitributor for marketing or program support:

Performance of the Trust

Explanation of Performance Terminology.  The Trust uses a variety of terms to
illustrate its performance. These terms include "yield," "compounded
effective yield" and "average annual total return."  An explanation of how
yields and total returns are calculated is set forth below.  The charts below
show the Trust's performance as of the Trust's most recent fiscal year end.
You can obtain current performance information by calling the Trust's
Transfer Agent at 1.800.525.9310.

      The Trust's illustrations of its performance data in advertisements
must comply with rules of the Securities and Exchange Commission.  Those
rules describe the types of performance data that may be used and how it is
to be calculated.  If the Trust shows total returns in addition to its
yields, the returns must be for the 1-, 5- and 10-year periods ending as of
the most recent calendar quarter prior to the publication of the
advertisement (or its submission for publication).

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

o     Yields and total returns measure the performance of a hypothetical
         account in the Trust over various periods and do not show the
         performance of each shareholder's account. Your account's
         performance will vary from the model performance data if your
         dividends are received in cash, or you buy or sell shares during the
         period, or you bought your shares at a different time than the
         shares used in the model.
o     An investment in the Trust is not insured by the FDIC or any other
         government agency.
o     The Trust's yield is not fixed or guaranteed and will fluctuate.
o     Yields and total returns for any given past period represent historical
         performance information and are not, and should not be considered, a
         prediction of future yields or returns.

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

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

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

|X|   Total Return Information.  There are different types of "total returns"
to measure the Trust's performance. Total return is the change in value of a
hypothetical investment in the Trust over a given period, assuming that all
dividends and capital gains distributions are reinvested in additional shares
and that the investment is redeemed at the end of the period.  The cumulative
total return measures the change in value over the entire period (for
example, ten years).  An average annual total return shows the average rate
of return for each year in a period that would produce the cumulative total
return over the entire period.  However, average annual total returns do not
show actual year-by-year performance.  The Trust uses standardized
calculations for its total returns as prescribed by the SEC.  The methodology
is discussed below.

o     Average Annual Total Return.  The "average annual total return" of each
class is an average annual compounded rate of return for each year in a
specified number of years.  It is the rate of return based on the change in
value of a hypothetical initial investment of $1,000 ("P" in the formula
below) held for a number of years ("n") to achieve an Ending Redeemable Value
("ERV" in the formula) of that investment, according to the following formula:

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

- ------------------------------------------------------------------------------
o     Cumulative Total Return.  The "cumulative total return" calculation
measures the change in value of a hypothetical investment of $1,000 over an
entire period of years.  Its calculation uses some of the same factors as
average annual total return, but it does not average the rate of return on an
annual basis.  Cumulative total return is determined as follows:

 ERV - P   = Total Return
- -----------

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

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

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

      From time to time the Trust may include in its advertisements and sales
literature the total return performance of a hypothetical investment account
that includes shares of the Trust and other Oppenheimer funds. The combined
account may be part of an illustration of an asset allocation model or
similar presentation. The account performance may combine total return
performance of the Trust and the total return performance of other
Oppenheimer funds included in the account. Additionally, from time to time,
the Trust's advertisements and sales literature may include, for illustrative
or comparative purposes, statistical data or other information about general
or specific market and economic conditions. That may include, for example,
o     information about the performance of certain securities or commodities
            markets or segments of those markets,
o     information about the performance of the economies of particular
            countries or regions,
o     the earnings of companies included in segments of particular
            industries, sectors, securities markets, countries or
            regions,
o     the availability of different types of securities or offerings of
            securities,
o     information relating to the gross national or gross domestic product of
            the United States or other countries or regions,
o     comparisons of various market sectors or indices to demonstrate
            performance, risk, or other characteristics of the Trust.

ABOUT YOUR ACCOUNT

How to Buy Shares

Determination of Net Asset Value Per Share. The net asset value per share of
the Trust is determined twice each day that the New York Stock Exchange (the
"NYSE") is open, at 12:00 Noon and at 4:00 p.m., on each day that the NYSE is
open, by dividing the value of the Trust's net assets by the total number of
shares outstanding. All references to time in this SAI mean "Eastern time."
The NYSE's most recent annual announcement regarding holidays and days when
the market may close early is available on the NYSE's website at www.nyse.com.

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

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


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


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

How to Sell Shares

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

Checkwriting.  When a check is presented to the Bank for clearance, the Bank
will ask the Trust to redeem a sufficient number of full and fractional
shares in the shareholder's account to cover the amount of the check.  This
enables the shareholder to continue receiving dividends on those shares until
the check is presented to the Trust.  Checks may not be presented for payment
at the offices of the Bank or the Trust's custodian.  This limitation does
not affect the use of checks for the payment of bills or to obtain cash at
other banks.  The Trust reserves the right to amend, suspend or discontinue
offering checkwriting privileges at any time.  The Fund will provide you with
notice whenever it is required to do so by applicable law.

      In choosing to take advantage of the checkwriting privilege, by signing
the account application or by completing a checkwriting card, each individual
who signs:
(1)   for individual accounts, represents that they are the registered
         owner(s) of the shares of the Trust in that account;
(2)   for accounts for corporations, partnerships, trusts and other entities,
         represents that they are an officer, general partner, trustee or
         other fiduciary or agent, as applicable, duly authorized to act on
         behalf of the registered owner(s);
(3)   authorizes the Trust, its Transfer Agent and any bank through which the
         Trust's drafts (checks) are payable to pay all checks drawn on the
         Trust account of such person(s) and to redeem a sufficient amount of
         shares from that account to cover payment of each check;
      (4)               specifically acknowledges that if they choose to
         permit checks to be honored if there is a single signature on checks
         drawn against joint accounts, or accounts for corporations,
         partnerships, trusts or other entities, the signature of any one
         signatory on a check will be sufficient to authorize payment of that
         check and redemption from the account, even if that account is
         registered in the names of more than one person or more than one
         authorized signature appears on the checkwriting card or the
         application, as applicable;
(5)   understands that the checkwriting privilege may be terminated or
         amended at any time by the Trust and/or the Trust's bank; and
(6)   acknowledges and agrees that neither the Trust nor its bank shall incur
         any liability for that amendment or termination of checkwriting
         privileges or for redeeming shares to pay checks reasonably believed
         by them to be genuine, or for returning or not paying checks that
         have not been accepted for any reason.


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


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

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

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

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

And the following money market funds:


Oppenheimer Cash Reserves                 Centennial Money Market Trust
Oppenheimer Money Market Fund, Inc.       Centennial New York Tax Exempt Trust
Centennial California Tax Exempt Trust    Centennial Tax Exempt Trust
Centennial Government Trust



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

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

|X| Telephone Exchange Requests.  When exchanging shares by telephone,  a direct
shareholder  must have an existing  account in the fund to which the exchange is
to be made. Otherwise, the investor must obtain a prospectus of that fund before
the exchange  request may be submitted.  If all telephone  lines are busy (which
might occur, for example,  during periods of substantial  market  fluctuations),
shareholders  might not be able to request exchanges by telephone and would have
to submit written exchange requests.

|X|  Processing  Exchange  Requests.  Shares to be exchanged are redeemed on the
regular  business day the Transfer Agent receives an exchange  request in proper
form (the "Redemption  Date").  Normally,  shares of the fund to be acquired are
purchased on the  Redemption  Date,  but such purchases may be delayed by either
fund up to five business days if it determines that it would be disadvantaged by
an immediate transfer of the redemption proceeds.  The Trust reserves the right,
in its discretion,  to refuse any exchange request that may disadvantage it. For
example,  if the  receipt of  multiple  exchange  requests  from a dealer  might
require the  disposition  of portfolio  securities  at a time or at a price that
might be disadvantageous to the Trust, the Trust may refuse the request.

     In connection with any exchange request, the number of shares exchanged may
be less than the number  requested if the exchange or the number requested would
include shares  subject to a restriction  cited in the Prospectus or this SAI or
would include  shares covered by a share  certificate  that is not tendered with
the request.  In those cases,  only the shares  available  for exchange  without
restriction will be exchanged.

     The  different   eligible  funds  available  for  exchange  have  different
investment objectives,  policies and risks. A shareholder should assure that the
fund selected is  appropriate  for his or her  investment and should be aware of
the tax  consequences  of an  exchange.  For  federal  income tax  purposes,  an
exchange  transaction  is  treated as a  redemption  of shares of one fund and a
purchase of shares of another. The Trust, the Distributor,  the Sub-Distributor,
and the Transfer Agent are unable to provide investment,  tax or legal advice to
a shareholder  in connection  with an exchange  request or any other  investment
transaction.

     The Trust may amend,  suspend or terminate  the  exchange  privilege at any
time. Although,  the Trust may impose these changes at any time, it will provide
you with notice of those changes  whenever it is required to do so by applicable
law. It may be required to provide 60 days notice prior to  materially  amending
or  terminating  the exchange  privilege.  That 60-day notice is not required in
extraordinary circumstances.

Dividends and Taxes

Tax Status of the Trust's  Dividends,  Distributions  and Redemptions of Shares.
The  federal  tax   treatment  of  the  Trust's   dividends  and  capital  gains
distributions is briefly highlighted in the Prospectus.  The following is only a
summary of certain additional tax considerations  generally  affecting the Trust
and its shareholders.

     The tax  discussion in the  Prospectus  and this SAI is based on tax law in
effect on the date of the Prospectus  and this SAI.  Those laws and  regulations
may be changed by legislative,  judicial,  or administrative  action,  sometimes
with  retroactive  effect.  State and local tax  treatment  of  ordinary  income
dividends and capital gain  dividends from  regulated  investment  companies may
differ from the  treatment  under the  Internal  Revenue Code  described  below.
Potential  purchasers  of shares of the  Trust  are urged to  consult  their tax
advisers with specific  reference to their own tax  circumstances as well as the
consequences  of federal,  state and local tax rules  affecting an investment in
the Trust.

|X| Qualification as a Regulated Investment Company. The Trust has elected to be
taxed as a regulated  investment  company  under  Subchapter  M of the  Internal
Revenue Code of 1986, as amended. As a regulated  investment company,  the Trust
is not subject to federal income tax on the portion of its net investment income
(that is, taxable interest, dividends, and other taxable ordinary income, net of
expenses)  and  capital  gain net income  (that is, the excess of net  long-term
capital  gains  over net  short-term  capital  losses)  that it  distributes  to
shareholders.  That qualification enables the Trust to "pass through" its income
and realized  capital gains to  shareholders  without having to pay tax on them.
This avoids a "double tax" on that income and capital gains,  since shareholders
normally  will be taxed on the dividends and capital gains they receive from the
Trust  (unless  their  Trust  shares  are held in a  retirement  account  or the
shareholder is otherwise exempt from tax).

     The Internal  Revenue Code contains a number of complex  tests  relating to
qualification  that the Trust might not meet in a particular year. If it did not
qualify as a regulated  investment  company,  the Trust would be treated for tax
purposes as an  ordinary  corporation  and would  receive no tax  deduction  for
payments made to shareholders.

     To qualify as a regulated  investment company, the Trust must distribute at
least 90% of its investment  company  taxable  income (in brief,  net investment
income and the excess of net short-term  capital gain over net long-term capital
loss)  for  the  taxable  year.  The  Trust  must  also  satisfy  certain  other
requirements of the Internal  Revenue Code,  some of which are described  below.
Distributions  by the Trust made during the  taxable  year or,  under  specified
circumstances,  within 12 months  after the close of the taxable  year,  will be
considered  distributions  of income  and gains  for the  taxable  year and will
therefore count toward satisfaction of the above-mentioned requirement.

     To qualify as a  regulated  investment  company,  the Trust must  derive at
least 90% of its gross income from dividends,  interest,  certain  payments with
respect to securities  loans,  gains from the sale or other disposition of stock
or  securities  or foreign  currencies  (to the extent such  currency  gains are
directly related to the regulated  investment  company's  principal  business of
investing in stock or securities) and certain other income.

     In addition to satisfying the requirements  described above, the Trust must
satisfy  an  asset  diversification  test in  order to  qualify  as a  regulated
investment company. Under that test, at the close of each quarter of the Trust's
taxable  year,  at least 50% of the value of the Trust's  assets must consist of
cash  and  cash  items  (including  receivables),  U.S.  government  securities,
securities of other  regulated  investment  companies,  and  securities of other
issuers. As to each of those issuers, the Trust must not have invested more than
5% of the value of the Trust's  total assets in  securities  of each such issuer
and the Trust must not hold more than 10% of the outstanding  voting  securities
of each such  issuer.  No more than 25% of the value of its total  assets may be
invested  in the  securities  of any one  issuer  (other  than  U.S.  government
securities and securities of other regulated investment companies), or in two or
more  issuers  which the Trust  controls  and which are  engaged  in the same or
similar trades or businesses.  For purposes of this test,  obligations issued or
guaranteed by certain agencies or  instrumentalities  of the U.S. government are
treated as U.S. government securities.

|X| Excise Tax on Regulated  Investment  Companies.  Under the Internal  Revenue
Code,  by December 31 each year,  the Trust must  distribute  98% of its taxable
investment income earned from January 1 through December 31 of that year and 98%
of its capital  gains  realized in the period from  November 1 of the prior year
through  October 31 of the current  year.  If it does not, the Trust must pay an
excise tax on the amounts not distributed.  It is presently anticipated that the
Trust  will meet  those  requirements.  To meet  this  requirement,  in  certain
circumstances the Trust might be required to liquidate portfolio  investments to
make sufficient distributions to avoid excise tax liability.  However, the Board
of Trustees and the Manager might  determine in a particular  year that it would
be in the  best  interests  of  shareholders  for the  Trust  not to  make  such
distributions  at  the  required  levels  and  to  pay  the  excise  tax  on the
undistributed  amounts.  That would reduce the amount of income or capital gains
available for distribution to shareholders.

|X|  Taxation  of  Trust  Distributions.   The  Trust  anticipates  distributing
substantially  all of its  investment  company  taxable  income for each taxable
year. Those distributions will be taxable to shareholders as ordinary income and
treated as dividends for federal income tax purposes.

     Special  provisions of the Internal  Revenue Code govern the eligibility of
the  Trust's  dividends  for  the  dividends-received  deduction  for  corporate
shareholders.  Long-term  capital gains  distributions  are not eligible for the
deduction.  The amount of  dividends  paid by the Trust that may qualify for the
deduction is limited to the aggregate  amount of qualifying  dividends  that the
Trust derives from portfolio  investments  that the Trust has held for a minimum
period,  usually 46 days. A corporate  shareholder  will not be eligible for the
deduction  on dividends  paid on Trust  shares held for 45 days or less.  To the
extent the Trust's dividends are derived from gross income from option premiums,
interest  income or  short-term  gains from the sale of  securities or dividends
from foreign  corporations,  those dividends will not qualify for the deduction.
Since it is  anticipated  that most of the Trust's  income will be derived  from
interest it receives on its investments,  the Trust does not anticipate that its
distributions will qualify for this deduction.

     The Trust may either retain or distribute to  shareholders  its net capital
gain for each taxable year. The Trust  currently  intends to distribute any such
amounts.  If net long term capital  gains are  distributed  and  designated as a
capital gain  distribution,  it will be taxable to  shareholders  as a long-term
capital gain and will be properly  identified in reports sent to shareholders in
January  of each  year.  Such  treatment  will  apply  no  matter  how  long the
shareholder  has held his or her shares or whether that gain was  recognized  by
the Trust before the shareholder acquired his or her shares.

     If the Trust  elects to retain  its net  capital  gain,  the Trust  will be
subject  to tax on it at the 35%  corporate  tax rate.  If the  Trust  elects to
retain its net capital gain, the Trust will provide to shareholders of record on
the last day of its taxable year  information  regarding their pro rata share of
the gain and tax paid. As a result,  each shareholder will be required to report
his or her pro rata share of such gain on their tax return as long-term  capital
gain,  will  receive a  refundable  tax credit for his/her pro rata share of tax
paid by the  Trust on the gain,  and will  increase  the tax  basis for  his/her
shares by an amount equal to the deemed distribution less the tax credit.

     Investment  income that may be received  by the Trust from  sources  within
foreign  countries may be subject to foreign taxes  withheld at the source.  The
United  States has entered into tax treaties with many foreign  countries  which
entitle the Trust to a reduced rate of, or exemption from, taxes on such income.

     Distributions by the Trust that do not constitute ordinary income dividends
or  capital  gain  distributions  will be  treated as a return of capital to the
extent  of the  shareholder's  tax basis in their  shares.  Any  excess  will be
treated as gain from the sale of those shares, as discussed below.  Shareholders
will be advised  annually  as to the U.S.  federal  income tax  consequences  of
distributions made (or deemed made) during the year. If prior distributions made
by the Trust must be  re-characterized as a non-taxable return of capital at the
end of the  fiscal  year as a result  of the  effect of the  Trust's  investment
policies, they will be identified as such in notices sent to shareholders.

     Distributions  by the Trust will be treated in the manner  described  above
regardless  of  whether  the  distributions  are paid in cash or  reinvested  in
additional  shares of the Trust (or of another fund).  Shareholders  receiving a
distribution  in the form of  additional  shares will be treated as  receiving a
distribution in an amount equal to the fair market value of the shares received,
determined as of the reinvestment date.

     The Trust will be  required in certain  cases to  withhold  28% of ordinary
income dividends, capital gains distributions and the proceeds of the redemption
of  shares,  paid to any  shareholder  (1) who has  failed to  provide a correct
taxpayer identification number or to properly certify that number when required,
(2) who is subject to backup  withholding  for  failure to report the receipt of
interest or dividend  income  properly,  or (3) who has failed to certify to the
Trust that the shareholder is not subject to backup withholding or is an "exempt
recipient" (such as a corporation). Any tax withheld by the Trust is remitted by
the  Trust  to the  U.S.  Treasury  and  is  identified  in  reports  mailed  to
shareholders in January of each year with a copy sent to the IRS.

|X| Tax Effects of  Redemptions  of Shares.  If a  shareholder  redeems all or a
portion of his/her shares,  the shareholder will recognize a gain or loss on the
redeemed shares in an amount equal to the difference between the proceeds of the
redeemed shares and the shareholder's adjusted tax basis in the shares. All or a
portion  of  any  loss  recognized  in  that  manner  may be  disallowed  if the
shareholder  purchases  other shares of the Trust within 30 days before or after
the redemption.

     In general,  any gain or loss arising from the  redemption of shares of the
Trust will be  considered  capital  gain or loss,  if the shares  were held as a
capital asset. It will be long-term capital gain or loss if the shares were held
for more than one year. However, any capital loss arising from the redemption of
shares held for six months or less will be treated as a long-term  capital  loss
to the extent of the amount of capital gain dividends  received on those shares.
Special holding period rules under the Internal  Revenue Code apply in this case
to  determine  the  holding  period  of  shares  and  there  are  limits  on the
deductibility of capital losses in any year.

|X| Foreign Shareholders. Under U.S. tax law, taxation of a shareholder who is a
foreign person (including, but not limited to, a nonresident alien individual, a
foreign  trust,  a  foreign  estate,  a  foreign   corporation,   or  a  foreign
partnership)  primarily  depends on whether the foreign person's income from the
Trust is  effectively  connected  with the conduct of a U.S.  trade or business.
Typically,   ordinary  income  dividends  paid  (not  including  exempt-interest
dividends paid by the Trust) from a mutual fund are not considered  "effectively
connected" income.

     Ordinary  income  dividends  that are paid by the Trust (and are deemed not
"effectively connected income") to foreign persons will be subject to a U.S. tax
withheld by the Trust at a rate of 30%,  provided  the Trust  obtains a properly
completed and signed  Certificate of Foreign Status. The tax rate may be reduced
if the  foreign  person's  country of  residence  has a tax treaty with the U.S.
allowing for a reduced tax rate on ordinary income  dividends paid by the Trust.
Any tax withheld by the Trust is remitted by the Trust to the U.S.  Treasury and
is identified  in reports  mailed to  shareholders  in March of each year with a
copy sent to the IRS.

     If the ordinary income  dividends from the Trust are effectively  connected
with the conduct of a U.S. trade or business,  then the foreign person may claim
an exemption  from the U.S. tax  described  above  provided the Trust  obtains a
properly completed and signed Certificate of Foreign Status.

     If the foreign person fails to provide a  certification  of his/her foreign
status,  the Trust will be  required to  withhold  U.S.  tax at a rate of 28% on
ordinary income dividends,  capital gains  distributions and the proceeds of the
redemption  of shares,  paid to any foreign  person.  Any tax  withheld (in this
situation)  by the Trust is  remitted by the Trust to the U.S.  Treasury  and is
identified in reports mailed to shareholders in January of each year with a copy
sent to the IRS.

     The tax  consequences to foreign persons  entitled to claim the benefits of
an applicable tax treaty may be different from those described  herein.  Foreign
shareholders  are urged to consult  their own tax advisors or the U.S.  Internal
Revenue  Service with respect to the particular tax  consequences  to them of an
investment in the Trust,  including the  applicability  of the U.S.  withholding
taxes described above.

Dividend  Reinvestment  in Another Trust.  Direct  shareholders of the Trust may
elect to reinvest all dividends  and/or capital gains  distributions  in Class A
shares of any eligible fund listed above. To elect this option,  the shareholder
must notify the Transfer  Agent in writing and must have an existing  account in
the fund selected for reinvestment. Otherwise, the shareholder first must obtain
a prospectus for that fund and an application  from the Distributor to establish
an account.  The investment will be made at the close of business on the payable
date of the dividend or distribution.

Additional Information About the Trust

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

The Transfer Agent.  Shareholder Services,  Inc., the Trust's Transfer Agent, is
responsible  for maintaining  the Trust's  shareholder  registry and shareholder
accounting  records,  and for paying dividends and distributions to shareholders
of  the  Trust.  It  also  handles  shareholder   servicing  and  administrative
functions. It serves as the Transfer Agent for an annual per account fee.

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF CENTENNIAL GOVERNMENT TRUST:

We have audited the accompanying statement of assets and liabilities of
Centennial Government Trust, including the statement of investments, as of June
30, 2006, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the five years in the periods
presented. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

      We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Trust is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. Our audit includes consideration
of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Trust's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of June 30, 2006, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audits provide a reasonable basis for
our opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Centennial Government Trust as of June 30, 2006, the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for each of the five
years in the periods presented, in conformity with accounting principles
generally accepted in the United States of America.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES

Centennial Government Trust (the Trust) is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
The Trust's investment objective is to seek a high level of current income that
is consistent with the preservation of capital and the maintenance of liquidity.
The Trust's investment advisor is Centennial Asset Management Corporation (the
Manager), a wholly owned subsidiary of OppenheimerFunds, Inc. (OFI).

      The following is a summary of significant accounting policies consistently
followed by the Trust.

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The net asset value of shares of the Trust is normally
determined twice each day, at 12:00 Noon Eastern time and at 4:00 P.M. Eastern
time on each day the New York Stock Exchange (the "Exchange") is open for
trading. Portfolio securities are valued on the basis of amortized cost, which
approximates market value.

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

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

The tax components of capital shown in the table below represent distribution
requirements the Trust must satisfy under the income tax regulations, losses the
Trust may be able to offset against income and gains realized in future years
for federal income tax purposes.

             UNDISTRIBUTED NET        UNDISTRIBUTED         ACCUMULATED LOSS

                    $1,658,516                  $--                   $4,521

1. As of June 30, 2006, the Trust had $4,372 of net capital loss carryforwards
available to offset future realized capital gains, if any, and thereby reduce
future taxable gain distributions. As of June 30, 2006, details of the capital
loss carryforwards were as follows:

                                 EXPIRING
                                 ------------------------

                                 Total             $4,372
                                                   ======

2. As of June 30, 2006, the Trust had $149 of post-October losses available to
offset future realized capital gains, if any. Such losses, if unutilized, will
expire in 2015.


                        12 | CENTENNIAL GOVERNMENT TRUST

3. During the fiscal year ended June 30, 2006, the Trust did not utilize any
capital loss carryforward.

4. During the fiscal year ended June 30, 2005, the Trust did not utilize any
capital loss carryforward.

Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Trust.

The tax character of distributions paid during the years ended June 30, 2006 and
June 30, 2005 was as follows:

                                      YEAR ENDED      YEAR ENDED
                                   JUNE 30, 2006   JUNE 30, 2005
     -----------------------------------------------------------
     Distributions paid from:
     Ordinary income                 $41,036,525     $19,140,213

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Board of Trustees has adopted a deferred
compensation plan for independent trustees that enables trustees to elect to
defer receipt of all or a portion of the annual compensation they are entitled
to receive from the Trust. For purposes of determining the amount owed to the
Trustee under the plan, deferred amounts are treated as though equal dollar
amounts had been invested in shares of the Trust or in other Oppenheimer funds
selected by the Trustee. The Trust purchases shares of the funds selected for
deferral by the Trustee in amounts equal to his or her deemed investment,
resulting in a Trust asset equal to the deferred compensation liability. Such
assets are included as a component of "Other" within the asset section of the
Statement of Assets and Liabilities. Deferral of trustees' fees under the plan
will not affect the net assets of the Trust, and will not materially affect the
Trust's assets, liabilities or net investment income per share. Amounts will be
deferred until distributed in accordance to the Plan.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date. Income distributions, if any, are declared
daily and paid monthly. Capital gain distributions, if any, are declared and
paid annually but may be paid at other times to maintain the net asset value per
share at $1.00.

- --------------------------------------------------------------------------------
CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may
include interest expense incurred by the Trust on any cash overdrafts of its
custodian account during the period. Such cash overdrafts may result from the
effects of failed trades in portfolio securities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Trust pays
interest to its custodian on such cash overdrafts, to the extent they are not
offset by positive cash balances maintained by the Trust, at a rate equal to the
Federal Funds Rate plus 0.50%. The "Reduction to custodian expenses" line item,
if applicable, represents earnings on cash balances maintained by the Trust
during the period. At June 30, 2006, the Trust had $118 of such earnings on cash

balances available to offset future custodian fees or interest expenses incurred
during the next fiscal year.

- --------------------------------------------------------------------------------
SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
Realized gains and losses on securities sold are determined on the basis of
identified cost.

- --------------------------------------------------------------------------------
INDEMNIFICATIONS. The Trust's organizational documents provide current and
former trustees and officers with a limited indemnification against liabilities
arising in connection with the performance of their duties to the Trust. In the
normal course of business, the Trust may also enter into contracts that provide
general indemnifications. The Trust's maximum exposure under these arrangements
is unknown as this would be dependent on future claims that may be made against
the Trust. The risk of material loss from such claims is considered remote.

- --------------------------------------------------------------------------------
OTHER. The preparation of financial statements in conformity with U.S. 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:

ADMINISTRATION SERVICE FEES. The Trust pays the Manager a fee of $1,500 per year
for preparing and filing the Trust's tax returns.

- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. Shareholder Services, Inc. (SSI) acts as the transfer and
shareholder servicing agent for the Trust and for other registered investment
companies. The Trust pays SSI a per account fee. For the year ended June 30,
2006, the Trust paid $771,218 to SSI for services to the Trust.

- --------------------------------------------------------------------------------
SERVICE PLAN (12B-1) FEES. The Trust has adopted a service plan. It reimburses
Centennial Asset Management Corporation, the Distributor, for a portion of its
costs incurred for services provided to accounts that hold shares of the Trust.
Reimbursement is made periodically, depending on asset size, at an annual rate
of up to 0.20% of the average annual net assets of the Trust. The Distributor
currently uses all of those fees to pay dealers, brokers, banks and other
financial institutions periodically for providing personal services and
maintenance of accounts of their customers that hold shares of the Trust. Fees
incurred by the Trust under the Plan are detailed in the Statement of

4. ILLIQUID SECURITIES

As of June 30, 2006, investments in securities included issues that are
illiquid. A security may be considered illiquid if it lacks a readily available
market or if its valuation has not changed for a certain period of time. The
Trust will not invest more than 10% of its net assets (determined at the time of
purchase and reviewed periodically) in illiquid securities. Securities that are
illiquid are marked with the applicable footnote on the Statement of
Investments.






               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) leading market positions in well-established
industries;  (b)  high  rates of  return  on funds  employed;  (c)  conservative
capitalization  structure  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:

MIG 1/VMIG 1: Denotes superior credit quality.  Excellent protection is afforded
by established  cash flows,  highly reliable  liquidity  support or demonstrated
broad-based access to the market for refinancing.

MIG 2/VMIG 2: Denotes  strong credit  quality.  Margins of protection  are ample
although not as large as in the preceding group.







Standard & Poor's Ratings Services, a division of The McGraw-Hill Companies,
Inc. ("Standard and Poor's")

The following  ratings by Standard and Poor's for  commercial  paper (defined by
Standard  and Poor's as debt  having an  original  maturity  of no more than 365
days) assess the likelihood of payment:  A-1: Obligation is rated in the highest
category.  The  obligor's  capacity  to meet  its  financial  commitment  on the
obligation  is  strong.  Within  this  category,  a plus  (+)  sign  designation
indicates the obligor's  capacity to meet its financial  obligation is extremely
strong.

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

Standard and Poor's ratings for Municipal Notes due in 3 years or less:

SP-1:  Strong  capacity to pay principal and  interest.  An issue  determined to
possess a very strong capacity to pay debt service is given a (+) designation.

SP-2:   Satisfactory   capacity  to  pay  principal  and  interest,   with  some
vulnerability  to adverse  financial  and economic  changes over the term of the
notes.

Standard and Poor's  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,
Standard  and Poor's note  rating  symbols  are used with the  commercial  paper
symbols (for example, "SP-1+/A-1+").


Fitch, Inc. ("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:

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

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

- -----------------------------------------
Dominion Bond Rating Service Limited
("DBRS")
- -----------------------------------------

R-1:  Short term debt rated "R-1 (high)" is of the highest credit  quality,  and
indicates  an entity  which  possesses  unquestioned  ability  to repay  current
liabilities as they fall due.  Entities rated in this category normally maintain
strong liquidity positions,  conservative debt levels and profitability which is
both stable and above  average.  Companies  achieving an "R-1 (high)" rating are
normally  leaders in  structurally  sound  industry  segments  with proven track
records,  sustainable  positive  future  results and no  substantial  qualifying
negative   factors.   Given  the  extremely  tough  definition  which  DBRS  has
established for an "R-1 (high)",  few entities are strong enough to achieve this
rating.  Short term debt rated "R-1 (middle)" is of superior credit quality and,
in most cases, ratings in this category differ from "R-1 (high)" credits to only
a small degree. Given the extremely tough definition which DBRS has for the "R-1
(high)" category (which few companies are able to achieve),  entities rated "R-1
(middle)" are also  considered  strong credits which  typically  exemplify above
average strength in key areas of consideration  for debt protection.  Short term
debt rated "R-1 (low)" is of satisfactory  credit quality.  The overall strength
and outlook for key liquidity,  debt and profitability ratios is not normally as
favorable as with higher rating categories,  but these  considerations are still
respectable.   Any  qualifying  negative  factors  which  exist  are  considered
manageable, and the entity is normally of sufficient size to have some influence
in its industry.

R-2:  Short term debt rated "R-2" is of adequate  credit  quality and within the
three subset grades (high,  middle,  low),  debt  protection  ranges from having
reasonable ability for timely repayment to a level which is considered only just
adequate.  The liquidity and debt ratios of entities in the "R-2" classification
are not as strong as those in the "R-1" category,  and the past and future trend
may suggest some risk of maintaining  the strength of key ratios in these areas.
Alternative sources of liquidity support are considered  satisfactory;  however,
even the  strongest  liquidity  support  will not improve the  commercial  paper
rating of the issuer.  The size of the entity may restrict its flexibility,  and
its  relative  position in the  industry is not  typically as strong as the "R-1
credit".  Profitability trends, past and future, may be less favorable, earnings
not as stable,  and there are often negative  qualifying  factors  present which
could also make the entity more  vulnerable to adverse  changes in financial and
economic conditions.

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  edged."  Interest  payments  are
protected  by a large or by an  exceptionally  stable  margin and  principal  is
secure.  While the various protective elements are likely to change, the changes
that can be  expected  are most  unlikely  to impair  the  fundamentally  strong
position of such issues.

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

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


Standard and Poor's

Bonds (including municipal bonds maturing beyond 3 years) are rated as follows:

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

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


Fitch

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

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

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